1 2003-05-27 Miguel de Icaza <miguel@ximian.com>
3 * class.cs (Field.Define): Add missing test for pointers and
6 2003-05-27 Ravi Pratap <ravi@ximian.com>
8 * expression.cs (ArrayAccess.GetStoreOpCode): For System.IntPtr,
9 we use the stobj opcode.
11 (ArrayCreation.EmitDynamicInitializers): Revert Miguel's patch
12 since it wasn't the correct fix.
14 It still is puzzling that we are required to use stobj for IntPtr
15 which seems to be a ValueType.
17 2003-05-26 Miguel de Icaza <miguel@ximian.com>
19 * ecore.cs (SimpleName.SimpleNameResolve): Consider using aliases
20 during regular simple name resolution. Now, the trick is that
21 instead of returning for processing the simplename, we do a
22 TypeManager.LookupType (ie, a rooted lookup as opposed to a
23 contextual lookup type). If a match is found, return that, if
24 not, return for further composition.
26 This fixes long-standing 30485.
28 * expression.cs (ArrayCreation.EmitDynamicInitializers): When
29 using the address to initialize an object, do an Stobj instead of
30 using the regular Stelem.
32 (IndexerAccess.Emit, IndexerAccess.EmitAssign):
33 Pass `is_base_indexer' to Invocation.EmitCall instead of false.
34 Because if we are a BaseIndexerAccess that value will be true.
37 * statement.cs (GotoCase.Resolve): Return after reporting an
38 error, do not attempt to continue.
40 * expression.cs (PointerArithmetic.Emit): If our operand is a
41 long, convert our constants to match the operand before
42 multiplying. Convert to I type before adding. Fixes 43670.
44 2003-05-14 Ravi Pratap <ravi@ximian.com>
46 * enum.cs (ImplicitConversionExists) : Rename to
47 ImplicitEnumConversionExists to remove ambiguity.
49 * ecore.cs (NullCast): New type of cast expression class which
50 basically is very similar to EmptyCast with the difference being
51 it still is a constant since it is used only to cast a null to
55 * convert.cs (ImplicitReferenceConversion): When casting a null
56 literal, we return a NullCast.
58 * literal.cs (NullLiteralTyped): Remove - I don't see why this
59 should be around anymore.
61 The renaming (reported was slightly wrong). Corrections:
63 ConvertImplicitStandard -> ImplicitConversionStandard
64 ConvertExplicitStandard -> ExplicitConversionStandard
66 * expression.cs (StaticCallExpr.MakeSimpleCall): Resolve arguments
67 before passing them in !
69 * convert.cs (ImplicitConversionStandard): When comparing for
70 equal expr and target types, ensure that expr is not a
73 In general, we must not be checking (expr_type ==
74 target_type) in the top level conversion methods
75 (ImplicitConversion, ExplicitConversion etc). This checking is
76 done in the methods that they delegate to.
78 2003-05-20 Miguel de Icaza <miguel@ximian.com>
80 * convert.cs: Move Error_CannotConvertType,
81 ImplicitReferenceConversion, ImplicitReferenceConversionExists,
82 ImplicitNumericConversion, ImplicitConversionExists,
83 ImplicitUserConversionExists, StandardConversionExists,
84 FindMostEncompassedType, FindMostSpecificSource,
85 FindMostSpecificTarget, ImplicitUserConversion,
86 ExplicitUserConversion, GetConversionOperators,
87 UserDefinedConversion, ConvertImplicit, ConvertImplicitStandard,
88 TryImplicitIntConversion, Error_CannotConvertImplicit,
89 ConvertImplicitRequired, ConvertNumericExplicit,
90 ExplicitReferenceConversionExists, ConvertReferenceExplicit,
91 ConvertExplicit, ConvertExplicitStandard from the ecore.cs into
94 Perform the following renames:
96 StandardConversionExists -> ImplicitStandardConversionExists
97 ConvertImplicit -> ImplicitConversion
98 ConvertImplicitStandard -> ImplicitStandardConversion
99 TryImplicitIntConversion -> ImplicitIntConversion
100 ConvertImplicitRequired -> ImplicitConversionRequired
101 ConvertNumericExplicit -> ExplicitNumericConversion
102 ConvertReferenceExplicit -> ExplicitReferenceConversion
103 ConvertExplicit -> ExplicitConversion
104 ConvertExplicitStandard -> ExplicitStandardConversion
106 2003-05-19 Martin Baulig <martin@ximian.com>
108 * statement.cs (TypeInfo.StructInfo): Made this type protected.
109 (TypeInfo): Added support for structs having structs as fields.
111 * ecore.cs (FieldExpr): Implement IVariable.
112 (FieldExpr.DoResolve): Call VariableInfo.GetSubStruct() to get the
113 VariableInfo for the field.
115 2003-05-18 Martin Baulig <martin@ximian.com>
117 * expression.cs (This.DoResolve): Report a CS0027 if we're
118 emitting a field initializer.
120 2003-05-18 Martin Baulig <martin@ximian.com>
122 * expression.cs (This.ResolveBase): New public function.
123 (This.DoResolve): Check for CS0188.
125 * codegen.cs (EmitContext.This): Just call This.ResolveBase(), not
128 * ecore.cs (MethodGroupExpr.DoResolve): Set the
129 `instance_expression' to null if we don't have any non-static
132 2003-05-18 Martin Baulig <martin@ximian.com>
134 Reworked the way how local variables and parameters are handled by
135 the flow analysis code.
137 * statement.cs (TypeInfo, VariableMap): New public classes.
138 (VariableInfo): New public class. This is now responsible for
139 checking whether a variable has been assigned. It is used for
140 parameters and local variables.
141 (Block.EmitMeta): Take the InternalParameters as argument; compute
142 the layout of the flow vectors here.
143 (Block.LocalMap, Block.ParameterMap): New public properties.
144 (FlowBranching): The .ctor doesn't get the InternalParameters
145 anymore since Block.EmitMeta() now computes the layout of the flow
147 (MyStructInfo): This class is now known as `StructInfo' and nested
148 in `TypeInfo'; we don't access this directly anymore.
150 * ecore.cs (IVariable): Added `VariableInfo VariableInfo'
151 property and removed IsAssigned(), IsFieldAssigned(),
152 SetAssigned() and SetFieldAssigned(); we now call them on the
153 VariableInfo so we don't need to duplicate this code everywhere.
155 * expression.cs (ParameterReference): Added `Block block' argument
157 (LocalVariableReference, ParameterReference, This): The new
158 VariableInfo class is now responsible for all the definite
161 * codegen.cs (EmitContext.IsVariableAssigned, SetVariableAssigned,
162 IsParameterAssigned, SetParameterAssigned): Removed.
164 2003-05-18 Martin Baulig <martin@ximian.com>
166 * typemanager.cs (InitCoreTypes): Try calling
167 SetCorlibTypeBuilders() with 4 args; if that fails, fall back to
168 the 3-args-version. Corlib now also needs our `void_type'.
169 (GetMethod): Added overloaded version which takes an optional
170 `bool report_errors' to allow lookups of optional methods.
172 2003-05-12 Martin Baulig <martin@ximian.com>
174 * statement.cs (VariableInfo): Renamed to LocalInfo since it's
175 only used for locals and not for parameters.
177 2003-05-12 Miguel de Icaza <miguel@ximian.com>
179 * support.cs (InternalParameters.ParameterType): Return the
180 ExternalType of the parameter.
182 * parameter.cs (Parameter.ExternalType): drop the two arguments,
185 2003-05-11 Miguel de Icaza <miguel@ximian.com>
187 * class.cs (MethodData.Define): Do not set the `newslot' on
188 interface members, if they are also flagged as "override".
190 * expression.cs (UnaryMutator.EmitCode): Simple workaround to emit
191 better code for ++i and i++. This only works for static fields
194 * typemanager.cs (LookupDeclSpace): Add new method, sometimes we
195 want to pull the DeclSpace out of the builder_to_declspace instead
196 of the TypeBuilder (like in TypeContainer.FindMembers).
198 * class.cs (TypeContainer.FindMembers): Use LookupDeclSpace
199 instead of LookupTypeContainer. Fixes the crash on .NET for
200 looking up interface members.
202 * const.cs: Create our own emit context during the Definition
203 stage, so that constants are evaluated in the proper context, when
204 a recursive definition happens.
206 2003-05-11 Martin Baulig <martin@ximian.com>
208 * statement.cs (Block.CreateSwitchBlock): New method. Creates a
209 new block for a switch section.
210 (Block.AddLabel, Block.LookupLabel): If we're a switch section, do
211 the adding/lookup in the switch block. Fixes #39828.
213 2003-05-09 Miguel de Icaza <miguel@ximian.com>
215 * expression.cs (UnaryMutator.LoadOneAndEmitOp): Missing
216 functionality: I needed to convert the data after I had performed
217 the add/sub operation into the operands type size.
219 * ecore.cs (ImplicitReferenceConversion): When boxing an interface
220 pass the type for the box operation, otherwise the resulting
221 object would have been of type object.
223 (BoxedCast): Add constructor to specify the type to box as.
225 2003-05-07 Miguel de Icaza <miguel@ximian.com>
227 * iterators.cs: I was reusing the `count' variable inadvertently,
228 take steps to not allow this to happen.
230 2003-05-06 Miguel de Icaza <miguel@ximian.com>
232 * attribute.cs (Attribute.Resolve): Params attributes are encoded
233 by creating an array at the point where the params starts and
234 putting all those arguments there, then adjusting the size of the
237 2003-05-05 Miguel de Icaza <miguel@ximian.com>
239 * expression.cs (New.AddressOf): Implement interface
240 IMemoryLocation. This is used when the `new' operator is used in
241 the context of an invocation to a method on a value type.
243 See http://bugzilla.ximian.com/show_bug.cgi?id=#42390 for an
246 * namespace.cs: Also check the using aliases here.
248 * driver.cs: Move the test for using validity after the types have
249 been entered, so we do a single pass that also includes the using
252 * statement.cs (Try.Resolve): Avoid crashing if there is a failure
253 in the regular case. CreateSiblingForFinally is doing extra
256 * attribute.cs (GetAttributeArgumentExpression): Store the result
257 on an out value, and use the return value to indicate failure
258 instead of using null (which is a valid return for Constant.GetValue).
260 * statement.cs: Perform the analysis flow for the increment
261 portion after the statement, because this will be the real flow of
262 execution. Fixes #42385
264 * codegen.cs (EmitContext.EmitArgument,
265 EmitContext.EmitStoreArgument): New helper functions when the
266 RemapToProxy flag is set.
268 * expression.cs (ParameterReference.EmitLdarg): Expose this useful
271 Add support for remapping parameters.
273 * iterators.cs: Propagate parameter values; Store parameter
274 values in the proxy classes.
276 2003-05-04 Miguel de Icaza <miguel@ximian.com>
278 * ecore.cs (FieldExpr): Fix an obvious bug. static fields do not
279 need a proxy reference; I do not know what I was thinking
281 * cs-parser.jay (constructor_initializer): catch another error,
282 and display nice message.
284 (field_declaration): catch void field declaration
285 to flag a better error.
287 * class.cs (MemberBase.CheckBase): Report an error instead of a
288 warning if a new protected member is declared in a struct.
289 (Field.Define): catch the error of readonly/volatile.
291 * ecore.cs (FieldExpr.EmitAssign): reuse the field lookup.
293 (FieldExpr.AddressOf): ditto. Catch error where the address of a
294 volatile variable is taken
296 2003-05-02 Miguel de Icaza <miguel@ximian.com>
298 * statement.cs (Fixed.Resolve): Report an error if we are not in
301 2003-05-01 Miguel de Icaza <miguel@ximian.com>
303 * typemanager.cs: reuse the code that handles type clashes for
304 delegates and enumerations.
306 * class.cs (Report28): Always report.
308 * expression.cs (EncodeAsAttribute): Allow nulls here.
310 2003-04-28 Miguel de Icaza <miguel@ximian.com>
312 * attribute.cs (Attribute.GetAttributeArgumentExpression): Moved
313 the functionality for testing whether an expression is valid for
314 an attribute here. Also handle the case of arrays of elements
317 * expression.cs (ArrayCreation.EncodeAsAttribute): Add support for
318 encoding a linear array into an array of objects that are suitable
319 to be passed to an CustomAttributeBuilder.
321 * delegate.cs: Check unsafe types being used outside of an Unsafe context.
323 * ecore.cs: (FieldExpr): Handle field remapping here.
325 * iteratators.cs: Pass the instance variable (if the method is an
326 instance method) to the constructors, so we can access the field
327 variables on the class.
329 TODO: Test this with structs. I think the THIS variable on
330 structs might have to be a pointer, and not a refenrece
332 2003-04-27 Miguel de Icaza <miguel@ximian.com>
334 * codegen.cs (EmitContext.Mapvariable): Adds a mechanism to map
335 local variables to fields in a proxy class.
337 * iterators.cs (PopulateProxy): Rename our internal fields to
339 Create a <THIS> field if we are an instance method, so we can
340 reference our parent container variables.
341 (MapVariable): Called back from the EmitContext code to enter a
342 new variable to field mapping into the proxy class (we just create
346 (LocalVariableReference.{Emit,EmitAssign,AddressOf}): Add support
347 for using the remapped locals to fields.
349 I placed the code here, because that gives the same semantics to
350 local variables, and only changes the Emit code.
352 * statement.cs (Fixed.Resolve): it is not allowed to have fixed
353 statements inside iterators.
354 (VariableInfo): Add a FieldBuilder for the cases when we are
355 remapping local variables to fields in a proxy class
357 * ecore.cs (SimpleNameResolve): Avoid testing two times for
358 current_block != null.
360 * statement.cs (Swithc.SimpleSwitchEmit): Removed code that did
361 not cope with strings, as it has been moved to the
362 TableSwitchEmit. Fixed bug in switch generation.
364 * expression.cs (New.DoResolve): Provide more context for the user
365 when reporting an error.
367 * ecore.cs (Expression.LoadFromPtr): Use ldind_i when loading
370 * expression.cs (MemberAccess.DoResolve): When we get a type back,
371 check the permissions for it. Note than in a type-resolution
372 context the check was already present in DeclSpace.ResolveType,
373 but was missing from the MemberAccess.
375 (ArrayCreation.CheckIndices): warn if the user has
376 more nested levels of expressions, but there are no more
377 dimensions specified. Avoids crash on bug 41906.
379 2003-04-26 Miguel de Icaza <miguel@ximian.com>
381 * statement.cs (Block): replace Implicit bool, for a generic
383 New flag: `Unchecked'. This is used during the EmitMeta phase
384 (which is out-of-line with the regular Resolve/Emit process for a
385 statement, as this is done ahead of time, but still gets a chance
386 to call constant resolve).
388 (Block.Flags): new enum for adding a new flag.
390 (Block.EmitMeta): track the state of unchecked.
392 (Unchecked): Set the "UnChecked" flags on any blocks we enclose,
393 to enable constant resolution to work there as well.
395 2003-04-22 Miguel de Icaza <miguel@ximian.com>
397 * typemanager.cs (ienumerable_type): Also look up
398 System.Collections.IEnumerable.
400 2003-04-21 Miguel de Icaza <miguel@ximian.com>
402 TODO: Test more than one conditional per method.
404 * class.cs (Indexer.Define): Report the location where the user is
405 referencing the unsupported feature.
407 (MethodData): Overload the use of `conditionals' to
408 minimize the creation of needless ArrayLists. This saves roughly
411 (Method): Implement the new IIteratorContainer interface.
412 (Method.SetYields): Implement the method by setting the ModFlags
413 to contain METHOD_YIELDS.
415 * expression.cs (Unary.ResolveOperator): Use expr_type, not Expr,
416 which just got set to null.
418 * iterators.cs: New file.
420 (Yield, YieldBreak): New statements.
422 * statement.cs (Return.Resolve): Flag an error if we are used in
425 * codegen.cs (InIterator): New flag set if the code is being
426 compiled in an iterator method.
428 * modifiers.cs: New flag METHOD_YIELDS. This modifier is an
429 internal modifier, and we just use it to avoid adding extra
430 fields, as this is seldom used.
432 * cs-parser.jay: Add yield_statement (yield and yield break).
434 * driver.cs: New flag -v2 to turn on version 2 features.
436 * cs-tokenizer.cs (Tokenizer): Add yield and __yield to the
437 hashtable when v2 is enabled.
439 2003-04-20 Miguel de Icaza <miguel@ximian.com>
441 * typemanager.cs (TypeManager.NamespaceClash): Use to check if
442 there is already a namespace defined with this name.
444 (TypeManager.InitCoreTypes): Remove the temporary workaround, as
445 people upgraded their corlibs.
447 (TypeManager.CoreLookupType): Use LookupTypeDirect, as we
448 always use fully qualified types, no need to use the compiler
451 (TypeManager.IsNamespace): Use binarysearch.
453 * class.cs (AddClass, AddStruct, AddInterface, AddEvent,
454 AddDelegate): I did not quite use the new IsValid API properly: I
455 have to pass the short-name and the fullname. I was passing only
456 the basename instead of the fullname sometimes.
458 (TypeContainer.DefineType): call NamespaceClash.
460 * interface.cs (Interface.DefineType): use NamespaceClash before
463 * delegate.cs (Delegate.DefineType): use NamespaceClash before
466 * enum.cs: (Enum.DefineType): use NamespaceClash before
469 * typemanager.cs (: 3-line patch that gives us some tasty 11%
470 speed increase. First, use the negative_hits cache when we get a
471 negative. Second, add the type with its full original name
472 instead of the new . and + encoded name (reflection uses + to
473 separate type from a nested type). Use LookupTypeReflection
474 directly which bypasses the type->name hashtable (that we already
475 know does not contain the type.
477 * decl.cs (DeclSpace.ResolveTypeExpr): track the
478 location/container type.
480 * driver.cs: When passing utf8, use directly the UTF8Encoding.
482 2003-04-19 Miguel de Icaza <miguel@ximian.com>
484 * decl.cs (ResolveTypeExpr): Mirror check acess here too.
486 * delegate.cs (NewDelegate.Resolve): Test whether an instance
487 method is being referenced in the method group from a static
488 context, and report error 120 if so.
490 * expression.cs, ecore.cs (Error_UnexpectedKind): New name for
493 * typemanager.cs: Add intermediate namespaces (if a namespace A.B
494 is created, we create the A namespace).
496 * cs-parser.jay: A namespace also introduces a DeclarationFound.
499 2003-04-18 Miguel de Icaza <miguel@ximian.com>
501 * typemanager.cs (GetReferenceType, GetPointerType): In .NET each
502 invocation to ModuleBuilder.GetType with the same values will
503 return a new type instance, so we need to cache its return
506 * expression.cs (Binary.ResolveOperator): Only allow the compare
507 operators on enums if they are of the same type.
509 * ecore.cs (Expression.ImplicitReferenceConversion): handle target
510 types of ValueType on their own case. Before we were giving them
511 the same treatment as objects.
513 * decl.cs (DeclSpace.IsValid): IsValid takes the short name and
514 fullname. Short name is used to compare against container name.
515 Fullname is used to check against defined namespace names.
517 * class.cs (AddProperty, AddField, AddClass, AddStruct, AddEnum,
518 AddDelegate, AddEvent): Pass new parameter to DeclSpace.IsValid
520 (Method.CheckBase): Call parent.
521 (MemberBase.CheckBase): Check for protected members on sealed
523 (PropertyBase.CheckBase): Call parent.
524 (Field.Define): Call parent.
526 * report.cs: Negative error codes are now mapped to 8000 - code,
527 so that the display is render more nicely.
529 * typemanager.cs: Do not use try/catch, instead report a regular
532 (GetPointerType, GetReferenceType): These methods provide
533 mechanisms to obtain the T* and T& from a T. We had the code
534 previously scattered around the code base, and it also used
535 TypeManager.LookupType that would go through plenty of caches.
536 This one goes directly to the type source.
538 In some places we did the Type.GetType followed by
539 ModuleBuilder.GetType, but not in others, so this unifies the
542 * namespace.cs (VerifyUsing): Perform a non-lazy approach to using
543 statements now that we have namespace information.
545 * typemanager.cs (IsNamespace): New method, returns whether the
546 string presented is a namespace or not.
548 (ComputeNamespaces): New public entry point, computes the list of
549 available namespaces, using the GetNamespaces API call in Mono, or
550 the slower version in MS.NET.
552 Now before we start the semantic analysis phase, we have a
553 complete list of namespaces including everything that the user has
556 Deleted old code to cache namespaces in .nsc files.
558 2003-04-17 Miguel de Icaza <miguel@ximian.com>
560 * class.cs: (TypeContainer.DefineDefaultConstructor): Use the
561 class/struct location definition Location for the implicit
562 constructor location.
564 (Operator.Define): Use the location of the operator for the
565 implicit Method definition.
567 (Constructor.Emit): use the constructor location for the implicit
568 base initializer constructor.
570 * ecore.cs: Remove ITypeExpression. This interface is now gone,
571 and the Expression class now contains two new methods:
573 ResolveAsTypeStep and ResolveAsTypeTerminal. This is used to
574 isolate type lookup from the rest of the resolution process.
576 Since we use Expressions to hold type definitions due to the way
577 we parse the input we have historically overloaded Resolve to
578 perform the Type lookups if a special flag is passed. Now this is
579 eliminated and two methods take their place.
581 The differences in the two methods between xStep and xTerminal is
582 that xStep is involved in our current lookup system that uses
583 SimpleNames to compose a name, while xTerminal is used just to
584 catch the case where the simplename lookup failed.
586 2003-04-16 Miguel de Icaza <miguel@ximian.com>
588 * expression.cs (ResolveMemberAccess): Remove redundant code.
589 TypeExpr expressions are always born fully resolved.
591 * interface.cs (PopulateMethod): Do not lookup the types twice.
592 We were doing it once during SemanticAnalysis and once during
595 * cs-parser.jay: Due to our hack in the grammar, things like A.B[]
596 in local variable type definitions, were being returned as a
597 SimpleName (we decomposed everything into a string), that is
598 because primary_expression was being used instead of a type in the
599 grammar (reduce/reduce conflicts).
601 The part that was wrong is that we converted the expression into a
602 string (an oversimplification in one hand, compounded with primary
603 expressions doing string concatenation).
609 Would return "A.B.C[]" as a SimpleName. This stopped things like
610 using clauses from working on this particular context. And a type
611 was being matched directly against "A.B.C[]".
613 We now use the correct approach, and allow for ComposedCast to be
614 part of the unary expression. So the "A.B.C []" become a composed
615 cast of "A.B.C" (as a nested group of MemberAccess with a
616 SimpleName at the end) plus the rank composition "[]".
620 2003-04-10 Miguel de Icaza <miguel@ximian.com>
622 * decl.cs (CheckAccessLevel): Implement the NestedPrivate rules
623 for the access level checking.
625 * class.cs: Cosmetic changes. Renamed `TypeContainer parent' to
626 `TypeContainer container', because I kept getting confused when I
627 was debugging this code.
629 * expression.cs (Indexers): Instead of tracking getters/setters,
630 we now track them in parallel. We create one arraylist less, but
631 most importantly it is possible now for the LValue code to find a
632 matching get for a set.
634 (IndexerAccess.DoResolveLValue): Update the code.
635 GetIndexersForType has been modified already to extract all the
636 indexers from a type. The code assumed it did not.
638 Also make the code set the correct return type for the indexer.
639 This was fixed a long time ago for properties, but was missing for
640 indexers. It used to be void_type.
642 (Binary.Emit): Test first for doubles instead of
643 floats, as they are more common.
645 (Binary.EmitBranchable): Use the .un version of the branch opcodes
646 when dealing with floats and the <=, >= operators. This fixes bug
649 * statement.cs (Foreach.EmitArrayForeach): bug fix: The code used
650 to load the array value by emitting a load on the foreach variable
651 type. This was incorrect.
653 We now emit the code to load an element using the the array
654 variable type, and then we emit the conversion operator.
658 2003-04-10 Zoltan Varga <vargaz@freemail.hu>
660 * attribute.cs: Avoid allocation of ArrayLists in the common case.
662 2003-04-09 Miguel de Icaza <miguel@ximian.com>
664 * class.cs (MethodSignature.InheritableMemberSignatureCompare):
665 test for protection before we test for signatures.
667 (MethodSignature.ToString): implement.
669 * expression.cs (Unary.TryReduceNegative): Add missing minus sign
670 to the case where we reduced into a LongConstant.
672 * decl.cs (CheckAccessLevel): If the type is an array, we can not
673 depend on whether the information is acurrate, because the
674 Microsoft runtime will always claim that the array type is public,
675 regardless of the real state.
677 If the type is a pointer, another problem happens: the type is
678 reported as non-public in Microsoft.
680 In both cases we have to call CheckAccessLevel recursively with
681 the underlying type as the argument to be tested.
683 2003-04-08 Miguel de Icaza <miguel@ximian.com>
685 * assign.cs (Assign.Emit): If we are dealing with a compound
686 assignment expression, we should use the code path that stores the
687 intermediate result in a temporary value. This fixes #40903.
689 *expression.cs (Indirection.ToString): Provide ToString method for
692 2003-04-08 Zoltan Varga <vargaz@freemail.hu>
694 * class.cs: Null out fields holding references to Block objects so
695 they can be garbage collected.
697 * expression.cs (OverloadResolve): Remove unused local.
699 2003-04-07 Martin Baulig <martin@ximian.com>
701 * codegen.cs (EmitContext.CurrentFile): New public field.
702 (EmitContext.Mark): Use the CurrentFile to check whether the
703 location is in the correct file.
704 (EmitContext.EmitTopBlock): Initialize CurrentFile here.
706 2003-04-07 Martin Baulig <martin@ximian.com>
708 * ecore.cs (Expression.ResolveBoolean): Don't call ec.Mark().
710 * codegen.cs (EmitContext.EmitTopBlock): Don't call Mark() on the
711 location. [FIXME: The location argument which gets passed to this
712 method is sometimes wrong!]
714 2003-04-07 Nick Drochak <ndrochak@gol.com>
716 * codegen.cs: Be more verbose when we can't find the symbol writer dll.
718 2003-04-07 Miguel de Icaza <miguel@ximian.com>
720 * expression.cs (Indirection.EmitAssign): We were using the
721 temporary, but returning immediately instead of continuing the
724 2003-04-06 Martin Baulig <martin@ximian.com>
726 * ecore.cs (SimpleName.SimpleNameResolve): Don't report an error
727 if it's a nested child, but also deriving from the outer class.
730 * typemanager.cs (IsNestedChildOf): Make this work if it's a
731 nested child, but also deriving from the outer class. See
733 (FilterWithClosure): We may access private members of the outer
734 class if we're a nested child and deriving from the outer class.
735 (RealMemberLookup): Only set `closure_private_ok' if the
736 `original_bf' contained BindingFlags.NonPublic.
738 2003-04-05 Martin Baulig <martin@ximian.com>
740 * statement.cs (FlowBranching.UsageVector.MergeChildren): Fix bug #40670.
742 2003-04-02 Miguel de Icaza <miguel@ximian.com>
744 * class.cs (Event.Define): Do not allow abstract events to have
747 2003-04-01 Miguel de Icaza <miguel@ximian.com>
749 * cs-parser.jay: Add error productions for ADD/REMOVE missing a
750 block in event declarations.
752 * ecore.cs (FieldExpr.AddressOf): If our instance expression is a
753 value type, get its address.
755 * expression.cs (Is.Emit): For action `LeaveOnStack' we were
756 leaving a class on the stack instead of a boolean value (int
757 0/1). Change the code so we compare against null, and then the
760 * class.cs (TypeContainer.GetClassBases): We were checking for the
761 parent class being sealed too late.
763 * expression.cs (Binary.Emit): For <= and >= when dealing with
764 floating point values, use cgt.un and clt.un instead of cgt and
767 2003-04-01 Zoltan Varga <vargaz@freemail.hu>
769 * statement.cs: Apply the same optimization as MS: skip the
770 GetEnumerator returning an IEnumerator, and use the one returning a
771 CharEnumerator instead. This allows us to avoid the try-finally block
774 2003-03-31 Gaurav Vaish <gvaish_mono@lycos.com>
776 * cs-parser.jay: Attributes cannot be applied to
777 namespaces. Fixes #40473
779 2003-03-31 Gonzalo Paniagua Javier <gonzalo@ximian.com>
782 (Add*): check if the name is valid using the full name for constants,
783 fields, properties and events.
785 2003-03-28 Miguel de Icaza <miguel@ximian.com>
787 * enum.cs (Enum.DefineType, Enum.IsValidEnumConstant): Also allow
788 char constants to be part of the enumeration.
790 * expression.cs (Conditional.DoResolve): Add support for operator
791 true. Implements the missing functionality from 14.12
793 * class.cs (TypeContainer.CheckPairedOperators): Report error for missmatch on
794 operator true/false as required by the spec.
796 * expression.cs (Unary.ResolveOperator): In LogicalNot, do an
797 implicit conversion to boolean.
799 * statement.cs (Statement.ResolveBoolean): A boolean expression is
800 also one where the type implements `operator true'.
802 * ecore.cs (Expression.GetOperatorTrue): New helper routine to
803 get an expression that will invoke operator true based on an
806 (GetConversionOperators): Removed the hack that called op_True
809 (Expression.ResolveBoolean): Move this from Statement.
811 2003-03-17 Miguel de Icaza <miguel@ximian.com>
813 * ecore.cs (FieldExpr): do not allow initialization of initonly
814 fields on derived classes
816 2003-03-13 Martin Baulig <martin@ximian.com>
818 * statement.cs (Block.Emit): Call ig.BeginScope() and
819 ig.EndScope() when compiling with debugging info; call
820 LocalBuilder.SetLocalSymInfo _after_ opening the scope.
822 2003-03-08 Miguel de Icaza <miguel@ximian.com>
824 * expression.cs (Indexers): Do not construct immediately, allow
825 for new members to be appended as we go. Fixes 38143
827 2003-03-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
829 * expression.cs: save/restore context when resolving an unchecked
832 2003-03-05 Miguel de Icaza <miguel@ximian.com>
834 * cfold.cs: Catch division by zero in modulus operator during
837 2003-03-03 Miguel de Icaza <miguel@ximian.com>
839 * interface.cs (Interface.DefineMembers): Avoid defining members
842 2003-02-27 Miguel de Icaza <miguel@ximian.com>
844 * driver.cs: handle the +/- options for -noconfig
846 * statement.cs (Unckeched.Resolve): Also track the state of
847 unchecked in the Resolve phase.
849 2003-02-27 Martin Baulig <martin@ximian.com>
851 * ecore.cs (Expression.MemberLookup): Don't create a
852 MethodGroupExpr for something which is not a method. Fixes #38291.
854 2003-02-25 Miguel de Icaza <miguel@ximian.com>
856 * class.cs (MemberBase.CheckParameters): Also check that the type
857 is unmanaged if it is a pointer.
859 * expression.cs (SizeOf.Resolve): Add location information.
861 * statement.cs (Block.EmitMeta): Flag error (208) if a pointer to
862 a managed type is declared.
864 * expression.cs (Invocation.VerifyArgumentsCompat): Check for the
865 parameter modifiers as well. Fixes bug 38606
867 * class.cs: Very sad. Am backing out the speed up changes
868 introduced by the ArrayList -> Array in the TypeContainer, as they
869 were not actually that much faster, and introduced a bug (no error
870 reports on duplicated methods).
872 * assign.cs (CompoundAssign.DoLResolve): Resolve the original
873 source first, this will guarantee that we have a valid expression
874 before calling in lower levels functions that will require a
875 resolved object. Then use this original_source in the
876 target.ResolveLValue instead of the original source that was
879 Another change. Use target.Resolve instead of LValueResolve.
880 Although we are resolving for LValues, we will let the Assign code
881 take care of that (it will be called again from Resolve). This
882 basically allows code like this:
884 class X { X operator + (X x, object o) {} X this [int idx] { get; set; } }
885 class Y { void A (X x) { x [0] += o; }
887 The problem was that the indexer was trying to resolve for
888 set_Item (idx, object o) and never finding one. The real set_Item
889 was set_Item (idx, X). By delaying the process we get the right
894 2003-02-23 Martin Baulig <martin@ximian.com>
896 * statement.cs (Block.Emit): Override this and set ec.CurrentBlock
897 while calling DoEmit ().
899 * codegen.cs (EmitContext.Mark): Don't mark locations in other
900 source files; if you use the #line directive inside a method, the
901 compiler stops emitting line numbers for the debugger until it
902 reaches the end of the method or another #line directive which
903 restores the original file.
905 2003-02-23 Martin Baulig <martin@ximian.com>
907 * statement.cs (FlowBranching.UsageVector.MergeChildren): Fix bug #37708.
909 2003-02-23 Martin Baulig <martin@ximian.com>
911 * statement.cs (Block.AddChildVariableNames): We need to call this
912 recursively, not just for our immediate children.
914 2003-02-23 Martin Baulig <martin@ximian.com>
916 * class.cs (Event.Define): Always make the field private, like csc does.
918 * typemanager.cs (TypeManager.RealMemberLookup): Make events
919 actually work, fixes bug #37521.
921 2003-02-23 Miguel de Icaza <miguel@ximian.com>
923 * delegate.cs: When creating the various temporary "Parameters"
924 classes, make sure that we call the ComputeAndDefineParameterTypes
925 on those new parameters (just like we do with the formal ones), to
926 allow them to be resolved in the context of the DeclSpace.
928 This fixes the bug that Dick observed in Bugzilla #38530.
930 2003-02-22 Miguel de Icaza <miguel@ximian.com>
932 * expression.cs (ResolveMemberAccess): When resolving a constant,
933 do not attempt to pull a constant if the value was not able to
934 generate a valid constant.
936 * const.cs (LookupConstantValue): Do not report more errors than required.
938 2003-02-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
940 * expression.cs: fixes bug #38328.
942 2003-02-18 Miguel de Icaza <miguel@ximian.com>
944 * class.cs: Changed all the various members that can be part of a
945 class from being an ArrayList to be an Array of the right type.
946 During the DefineType type_list, interface_list, delegate_list and
947 enum_list are turned into types, interfaces, delegates and enums
950 And during the member population, indexer_list, event_list,
951 constant_list, field_list, instance_constructor_list, method_list,
952 operator_list and property_list are turned into their real arrays.
954 Although we could probably perform this operation earlier, for
955 good error reporting we need to keep the lists and remove the
956 lists for longer than required.
958 This optimization was triggered by Paolo profiling the compiler
959 speed on the output of `gen-sample-program.pl' perl script.
961 * decl.cs (DeclSpace.ResolveType): Set the ContainerType, so we do
962 not crash in methods like MemberLookupFailed that use this field.
964 This problem arises when the compiler fails to resolve a type
965 during interface type definition for example.
967 2003-02-18 Miguel de Icaza <miguel@ximian.com>
969 * expression.cs (Indexers.GetIndexersForType): Interfaces do not
970 inherit from System.Object, so we have to stop at null, not only
971 when reaching System.Object.
973 2003-02-17 Miguel de Icaza <miguel@ximian.com>
975 * expression.cs: (Indexers.GetIndexersForType): Martin's fix used
976 DeclaredOnly because the parent indexer might have had a different
977 name, but did not loop until the top of the hierarchy was reached.
979 The problem this one fixes is 35492: when a class implemented an
980 indexer from an interface, we were getting the interface method
981 (which was abstract) and we were flagging an error (can not invoke
984 This also keeps bug 33089 functioning, and test-148 functioning.
986 * typemanager.cs (IsSpecialMethod): The correct way of figuring
987 out if a method is special is to see if it is declared in a
988 property or event, or whether it is one of the predefined operator
989 names. This should fix correctly #36804.
991 2003-02-15 Miguel de Icaza <miguel@ximian.com>
993 The goal here is to remove the dependency on EmptyCast.Peel ().
994 Killing it completely.
996 The problem is that currently in a number of places where
997 constants are expected, we have to "probe" for an EmptyCast, and
998 Peel, which is not the correct thing to do, as this will be
999 repetitive and will likely lead to errors.
1001 The idea is to remove any EmptyCasts that are used in casts that
1002 can be reduced to constants, so we only have to cope with
1005 This bug hunt was triggered by Bug 37363 and the desire to remove
1006 the duplicate pattern where we were "peeling" emptycasts to check
1007 whether they were constants. Now constants will always be
1010 * ecore.cs: Use an enumconstant here instead of wrapping with
1013 * expression.cs (Cast.TryReduce): Ah, the tricky EnumConstant was
1014 throwing me off. By handling this we can get rid of a few hacks.
1016 * statement.cs (Switch): Removed Peel() code.
1018 2003-02-14 Miguel de Icaza <miguel@ximian.com>
1020 * class.cs: Location information for error 508
1022 * expression.cs (New.DoResolve): Add a guard against double
1023 resolution of an expression.
1025 The New DoResolve might be called twice when initializing field
1026 expressions (see EmitFieldInitializers, the call to
1027 GetInitializerExpression will perform a resolve on the expression,
1028 and later the assign will trigger another resolution
1030 This leads to bugs (#37014)
1032 * delegate.cs: The signature for EndInvoke should contain any ref
1033 or out parameters as well. We were not doing this in the past.
1035 * class.cs (Field.Define): Do not overwrite the type definition
1036 inside the `volatile' group. Turns out that volatile enumerations
1037 were changing the type here to perform a validity test, which
1040 2003-02-12 Miguel de Icaza <miguel@ximian.com>
1042 * ecore.cs (FieldExpr.AddressOf): In the particular case of This
1043 and structs, we do not want to load the instance variable
1045 (ImplicitReferenceConversion, ImplicitReferenceConversionExists):
1046 enum_type has to be handled like an object reference (implicit
1047 conversions exists from this to object), but the regular IsClass
1048 and IsValueType tests will never return true for this one.
1050 Also we use TypeManager.IsValueType instead of type.IsValueType,
1051 just for consistency with the rest of the code (this is only
1052 needed if we ever use the construct exposed by test-180.cs inside
1053 corlib, which we dont today).
1055 2003-02-12 Zoltan Varga <vargaz@freemail.hu>
1057 * attribute.cs (ApplyAttributes): apply all MethodImplAttributes, not
1060 2003-02-09 Martin Baulig <martin@ximian.com>
1062 * namespace.cs (Namespace..ctor): Added SourceFile argument.
1063 (Namespace.DefineNamespaces): New static public method; this is
1064 called when we're compiling with debugging to add all namespaces
1067 * tree.cs (Tree.RecordNamespace): Added SourceFile argument and
1068 pass it to the Namespace's .ctor.
1070 * symbolwriter.cs (SymbolWriter.OpenMethod): Added TypeContainer
1071 and MethodBase arguments; pass the namespace ID to the symwriter;
1072 pass the MethodBase instead of the token to the symwriter.
1073 (SymbolWriter.DefineNamespace): New method to add a namespace to
1076 2003-02-09 Martin Baulig <martin@ximian.com>
1078 * symbolwriter.cs: New file. This is a wrapper around
1079 ISymbolWriter with a cleaner API. We'll dynamically Invoke()
1080 methods here in near future.
1082 2003-02-09 Martin Baulig <martin@ximian.com>
1084 * codegen.cs (EmitContext.Mark): Just pass the arguments to
1085 ILGenerator.MarkSequencePoint() which are actually used by the
1088 2003-02-09 Martin Baulig <martin@ximian.com>
1090 * location.cs (SourceFile): New public sealed class. This
1091 contains the name and an index which is used in the location's token.
1092 (Location): Reserve an appropriate number of bits in the token for
1093 the source file instead of walking over that list, this gives us a
1094 really huge performance improvement when compiling with debugging.
1096 * driver.cs (Driver.parse, Driver.tokenize_file): Take a
1097 `SourceFile' argument instead of a string.
1098 (Driver.ProcessFile): Add all the files via Location.AddFile(),
1099 but don't parse/tokenize here, we need to generate the list of all
1100 source files before we do that.
1101 (Driver.ProcessFiles): New static function. Parses/tokenizes all
1104 * cs-parser.jay (CSharpParser): Take a `SourceFile' argument
1105 instead of a string.
1107 * cs-tokenizer.cs (Tokenizer): Take `SourceFile' argument instead
1110 2003-02-09 Martin Baulig <martin@ximian.com>
1112 * cs-tokenizer.cs (Tokenizer.PreProcessLine): Also reset the
1113 filename on `#line default'.
1115 Sat Feb 8 17:03:16 CET 2003 Paolo Molaro <lupus@ximian.com>
1117 * statement.cs: don't clear the pinned var when the fixed statement
1118 returns from the method (fixes bug#37752).
1120 Sat Feb 8 12:58:06 CET 2003 Paolo Molaro <lupus@ximian.com>
1122 * typemanager.cs: fix from mathpup@mylinuxisp.com (Marcus Urban)
1125 2003-02-07 Martin Baulig <martin@ximian.com>
1127 * driver.cs: Removed the `--debug-args' command line argument.
1129 * codegen.cs (CodeGen.SaveSymbols): Removed, this is now done
1130 automatically by the AsssemblyBuilder.
1131 (CodeGen.InitializeSymbolWriter): We don't need to call any
1132 initialization function on the symbol writer anymore. This method
1133 doesn't take any arguments.
1135 2003-02-03 Miguel de Icaza <miguel@ximian.com>
1137 * driver.cs: (AddAssemblyAndDeps, LoadAssembly): Enter the types
1138 from referenced assemblies as well.
1140 2003-02-02 Martin Baulig <martin@ximian.com>
1142 * class.cs (MethodData.Emit): Generate debugging info for external methods.
1144 2003-02-02 Martin Baulig <martin@ximian.com>
1146 * class.cs (Constructor.Emit): Open the symbol writer before
1147 emitting the constructor initializer.
1148 (ConstructorInitializer.Emit): Call ec.Mark() to allow
1149 single-stepping through constructor initializers.
1151 2003-01-30 Miguel de Icaza <miguel@ximian.com>
1153 * class.cs: Handle error 549: do not allow virtual methods in
1156 2003-02-01 Jackson Harper <jackson@latitudegeo.com>
1158 * decl.cs: Check access levels when resolving types
1160 2003-01-31 Jackson Harper <jackson@latitudegeo.com>
1162 * statement.cs: Add parameters and locals set in catch blocks that might
1163 return to set vector
1165 2003-01-29 Miguel de Icaza <miguel@ximian.com>
1167 * class.cs (Operator): Set the SpecialName flags for operators.
1169 * expression.cs (Invocation.DoResolve): Only block calls to
1170 accessors and operators on SpecialName methods.
1172 (Cast.TryReduce): Handle conversions from char constants.
1175 Tue Jan 28 17:30:57 CET 2003 Paolo Molaro <lupus@ximian.com>
1177 * statement.cs: small memory and time optimization in FlowBranching.
1179 2003-01-28 Pedro Mart <yoros@wanadoo.es>
1181 * expression.cs (IndexerAccess.DoResolveLValue): Resolve the same
1182 problem that the last fix but in the other sid (Set).
1184 * expression.cs (IndexerAccess.DoResolve): Fix a problem with a null
1185 access when there is no indexer in the hierarchy.
1187 2003-01-27 Jackson Harper <jackson@latitudegeo.com>
1189 * class.cs: Combine some if statements.
1191 2003-01-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1193 * driver.cs: fixed bug #37187.
1195 2003-01-27 Pedro Martinez Juliá <yoros@wanadoo.es>
1197 * expression.cs (IndexerAccess.DoResolve): Before trying to resolve
1198 any indexer, it's needed to build a list with all the indexers in the
1199 hierarchy (AllGetters), else we have problems. Fixes #35653.
1201 2003-01-23 Miguel de Icaza <miguel@ximian.com>
1203 * class.cs (MethodData.Define): It is wrong for an interface
1204 implementation to be static in both cases: explicit and implicit.
1205 We were only handling this in one case.
1207 Improve the if situation there to not have negations.
1209 * class.cs (Field.Define): Turns out that we do not need to check
1210 the unsafe bit on field definition, only on usage. Remove the test.
1212 2003-01-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1214 * driver.cs: use assembly.Location instead of Codebase (the latest
1215 patch made mcs fail when using MS assemblies).
1217 2003-01-21 Tim Haynes <thaynes@openlinksw.com>
1219 * driver.cs: use DirectorySeparatorChar instead of a hardcoded "/" to
1220 get the path to *corlib.dll.
1222 2003-01-21 Nick Drochak <ndrochak@gol.com>
1226 * typemanager.cs: Remove compiler warnings
1228 2003-01-20 Duncan Mak <duncan@ximian.com>
1230 * AssemblyInfo.cs: Bump the version number to 0.19.
1232 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1234 * cs-tokenizer.cs: little fixes to line numbering when #line is used.
1236 2003-01-18 Zoltan Varga <vargaz@freemail.hu>
1238 * class.cs (Constructor::Emit): Emit debugging info for constructors.
1240 2003-01-17 Miguel de Icaza <miguel@ximian.com>
1242 * cs-parser.jay: Small fix: we were not comparing the constructor
1243 name correctly. Thanks to Zoltan for the initial pointer.
1245 2003-01-16 Jackson Harper <jackson@latitudegeo.com>
1247 * cs-tokenizer.cs: Set file name when specified with #line
1249 2003-01-15 Miguel de Icaza <miguel@ximian.com>
1251 * cs-parser.jay: Only perform the constructor checks here if we
1252 are named like the class; This will help provider a better
1253 error. The constructor path is taken when a type definition is
1254 not found, but most likely the user forgot to add the type, so
1255 report that rather than the constructor error.
1257 Tue Jan 14 10:36:49 CET 2003 Paolo Molaro <lupus@ximian.com>
1259 * class.cs, rootcontext.cs: small changes to avoid unnecessary memory
1262 2003-01-13 Jackson Harper <jackson@latitudegeo.com>
1264 * cs-parser.jay: Add cleanup call.
1266 2003-01-13 Duncan Mak <duncan@ximian.com>
1268 * cs-tokenizer.cs (Cleanup): Rename to 'cleanup' to make it more
1269 consistent with other methods.
1271 2003-01-13 Jackson Harper <jackson@latitudegeo.com>
1273 * cs-tokenizer.cs: Add Cleanup method, also fix #region error messages.
1275 Sun Jan 12 19:58:42 CET 2003 Paolo Molaro <lupus@ximian.com>
1277 * attribute.cs: only set GuidAttr to true when we have a
1280 2003-01-09 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1284 * typemanager.cs: fixes to allow mcs compile corlib with the new
1285 Type.IsSubclassOf fix.
1287 2003-01-08 Miguel de Icaza <miguel@ximian.com>
1289 * expression.cs (LocalVariableReference.DoResolve): Classify a
1290 constant as a value, not as a variable. Also, set the type for
1293 * cs-parser.jay (fixed_statement): take a type instead of a
1294 pointer_type, so we can produce a better error message later.
1296 * statement.cs (Fixed.Resolve): Flag types that are not pointers
1299 (For.DoEmit): Make inifinite loops have a
1300 non-conditional branch back.
1302 (Fixed.DoEmit): First populate the pinned variables, then emit the
1303 statement, then clear the variables. Before I was emitting the
1304 code once for each fixed piece.
1307 2003-01-08 Martin Baulig <martin@ximian.com>
1309 * statement.cs (FlowBranching.MergeChild): A break in a
1310 SWITCH_SECTION does not leave a loop. Fixes #36155.
1312 2003-01-08 Martin Baulig <martin@ximian.com>
1314 * statement.cs (FlowBranching.CheckOutParameters): `struct_params'
1315 lives in the same number space than `param_map'. Fixes #36154.
1317 2003-01-07 Miguel de Icaza <miguel@ximian.com>
1319 * cs-parser.jay (constructor_declaration): Set the
1320 Constructor.ModFlags before probing for it. This makes the
1321 compiler report 514, 515 and 132 (the code was there, but got
1324 * statement.cs (Goto.Resolve): Set `Returns' to ALWAYS.
1325 (GotoDefault.Resolve): Set `Returns' to ALWAYS.
1326 (GotoCase.Resolve): Set `Returns' to ALWAYS.
1328 Tue Jan 7 18:32:24 CET 2003 Paolo Molaro <lupus@ximian.com>
1330 * enum.cs: create the enum static fields using the enum type.
1332 Tue Jan 7 18:23:44 CET 2003 Paolo Molaro <lupus@ximian.com>
1334 * class.cs: don't try to create the ParamBuilder for the return
1335 type if it's not needed (and handle it breaking for the ms runtime
1338 2003-01-06 Jackson Harper <jackson@latitudegeo.com>
1340 * cs-tokenizer.cs: Add REGION flag to #region directives, and add checks to make sure that regions are being poped correctly
1342 2002-12-29 Miguel de Icaza <miguel@ximian.com>
1344 * cs-tokenizer.cs (get_cmd_arg): Fixups to allow \r to terminate
1345 the command. This showed up while compiling the JANET source
1346 code, which used \r as its only newline separator.
1348 2002-12-28 Miguel de Icaza <miguel@ximian.com>
1350 * class.cs (Method.Define): If we are an operator (because it
1351 reuses our code), then set the SpecialName and HideBySig. #36128
1353 2002-12-22 Miguel de Icaza <miguel@ximian.com>
1355 * ecore.cs (FieldExpr.DoResolve): Instead of throwing an
1356 exception, report error 120 `object reference required'.
1358 * driver.cs: Add --pause option, used during to measure the size
1359 of the process as it goes with --timestamp.
1361 * expression.cs (Invocation.DoResolve): Do not allow methods with
1362 SpecialName to be invoked.
1364 2002-12-21 Miguel de Icaza <miguel@ximian.com>
1366 * cs-tokenizer.cs: Small fix to the parser: compute the ascii
1367 number before adding it.
1369 2002-12-21 Ravi Pratap <ravi@ximian.com>
1371 * ecore.cs (StandardImplicitConversion): When in an unsafe
1372 context, we allow conversion between void * to any other pointer
1373 type. This fixes bug #35973.
1375 2002-12-20 Jackson Harper <jackson@latitudegeo.com>
1377 * codegen.cs: Use Path.GetFileNameWithoutExtension so an exception
1378 is not thrown when extensionless outputs are used
1380 2002-12-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1382 * rootcontext.cs: fixed compilation of corlib.
1384 2002-12-19 Miguel de Icaza <miguel@ximian.com>
1386 * attribute.cs (Attributes.Contains): Add new method.
1388 * class.cs (MethodCore.LabelParameters): if the parameter is an
1389 `out' parameter, check that no attribute `[In]' has been passed.
1391 * enum.cs: Handle the `value__' name in an enumeration.
1393 2002-12-14 Jaroslaw Kowalski <jarek@atm.com.pl>
1395 * decl.cs: Added special case to allow overrides on "protected
1398 2002-12-18 Ravi Pratap <ravi@ximian.com>
1400 * attribute.cs (Attributes.AddAttributeSection): Rename to this
1401 since it makes much more sense.
1403 (Attributes.ctor): Don't require a Location parameter.
1405 * rootcontext.cs (AddGlobalAttributeSection): Rename again.
1407 * attribute.cs (ApplyAttributes): Remove extra Location parameters
1408 since we already have that information per attribute.
1410 * everywhere : make appropriate changes.
1412 * class.cs (LabelParameters): Write the code which actually
1413 applies attributes to the return type. We can't do this on the MS
1414 .NET runtime so we flag a warning in the case an exception is
1417 2002-12-18 Miguel de Icaza <miguel@ximian.com>
1419 * const.cs: Handle implicit null conversions here too.
1421 2002-12-17 Ravi Pratap <ravi@ximian.com>
1423 * class.cs (MethodCore.LabelParameters): Remove the extra
1424 Type [] parameter since it is completely unnecessary. Instead
1425 pass in the method's attributes so that we can extract
1426 the "return" attribute.
1428 2002-12-17 Miguel de Icaza <miguel@ximian.com>
1430 * cs-parser.jay (parse): Use Report.Error to flag errors instead
1431 of ignoring it and letting the compile continue.
1433 * typemanager.cs (ChangeType): use an extra argument to return an
1434 error condition instead of throwing an exception.
1436 2002-12-15 Miguel de Icaza <miguel@ximian.com>
1438 * expression.cs (Unary.TryReduce): mimic the code for the regular
1439 code path. Perform an implicit cast in the cases where we can
1440 implicitly convert to one of the integral types, and then reduce
1441 based on that constant. This fixes bug #35483.
1443 2002-12-14 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1445 * typemanager.cs: fixed cut & paste error in GetRemoveMethod.
1447 2002-12-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1449 * namespace.cs: fixed bug #35489.
1451 2002-12-12 Miguel de Icaza <miguel@ximian.com>
1453 * class.cs: Remove some dead code.
1455 * cs-parser.jay: Estimate the number of methods needed
1456 (RootContext.MethodCount);
1458 * cs-tokenizer.cs: Use char arrays for parsing identifiers and
1459 numbers instead of StringBuilders.
1461 * support.cs (PtrHashtable): Add constructor with initial size;
1462 We can now reduce reallocations of the method table.
1464 2002-12-10 Ravi Pratap <ravi@ximian.com>
1466 * attribute.cs (ApplyAttributes): Keep track of the emitted
1467 attributes on a per-target basis. This fixes bug #35413.
1469 2002-12-10 Miguel de Icaza <miguel@ximian.com>
1471 * driver.cs (MainDriver): On rotor encoding 28591 does not exist,
1472 default to the Windows 1252 encoding.
1474 (UnixParseOption): Support version, thanks to Alp for the missing
1477 * AssemblyInfo.cs: Add nice assembly information.
1479 * cs-tokenizer.cs: Add fix from Felix to the #if/#else handler
1482 * cs-parser.jay: Allow a trailing comma before the close bracked
1483 in the attribute_section production.
1485 * ecore.cs (FieldExpr.AddressOf): Until I figure out why the
1486 address of the instance was being taken, I will take this out,
1487 because we take the address of the object immediately here.
1489 2002-12-09 Ravi Pratap <ravi@ximian.com>
1491 * typemanager.cs (AreMultipleAllowed): Take care of the most
1492 obvious case where attribute type is not in the current assembly -
1495 2002-12-08 Miguel de Icaza <miguel@ximian.com>
1497 * ecore.cs (SimpleName.DoResolve): First perform lookups on using
1498 definitions, instead of doing that afterwards.
1500 Also we use a nice little hack, depending on the constructor, we
1501 know if we are a "composed" name or a simple name. Hence, we
1502 avoid the IndexOf test, and we avoid
1504 * codegen.cs: Add code to assist in a bug reporter to track down
1505 the source of a compiler crash.
1507 2002-12-07 Ravi Pratap <ravi@ximian.com>
1509 * attribute.cs (Attribute.ApplyAttributes) : Keep track of which attribute
1510 types have been emitted for a given element and flag an error
1511 if something which does not have AllowMultiple set is used more
1514 * typemanager.cs (RegisterAttributeAllowMultiple): Keep track of
1515 attribute types and their corresponding AllowMultiple properties
1517 (AreMultipleAllowed): Check the property for a given type.
1519 * attribute.cs (Attribute.ApplyAttributes): Register the AllowMultiple
1520 property in the case we have a TypeContainer.
1522 (Attributes.AddAttribute): Detect duplicates and just skip on
1523 adding them. This trivial fix catches a pretty gross error in our
1524 attribute emission - global attributes were being emitted twice!
1526 Bugzilla bug #33187 is now fixed.
1528 2002-12-06 Miguel de Icaza <miguel@ximian.com>
1530 * cs-tokenizer.cs (pp_expr): Properly recurse here (use pp_expr
1533 * expression.cs (Binary.ResolveOperator): I can only use the
1534 Concat (string, string, string) and Concat (string, string,
1535 string, string) if the child is actually a concatenation of
1538 2002-12-04 Miguel de Icaza <miguel@ximian.com>
1540 * cs-tokenizer.cs: Small fix, because decimal_digits is used in a
1541 context where we need a 2-character lookahead.
1543 * pending.cs (PendingImplementation): Rework so we can keep track
1544 of interface types all the time, and flag those which were
1545 implemented by parents as optional.
1547 2002-12-03 Miguel de Icaza <miguel@ximian.com>
1549 * expression.cs (Binary.ResolveOperator): Use
1550 String.Concat(string,string,string) or
1551 String.Concat(string,string,string,string) when possible.
1553 * typemanager: More helper methods.
1556 Tue Dec 3 19:32:04 CET 2002 Paolo Molaro <lupus@ximian.com>
1558 * pending.cs: remove the bogus return from GetMissingInterfaces()
1559 (see the 2002-11-06 entry: the mono runtime is now fixed in cvs).
1561 2002-12-02 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1563 * namespace.cs: avoid duplicated 'using xxx' being added to
1564 using_clauses. This prevents mcs from issuing and 'ambiguous type' error
1565 when we get more than one 'using' statement for the same namespace.
1566 Report a CS0105 warning for it.
1568 2002-11-30 Miguel de Icaza <miguel@ximian.com>
1570 * cs-tokenizer.cs (consume_identifier): use read directly, instead
1571 of calling getChar/putback, uses internal knowledge of it.
1573 (xtoken): Reorder tokenizer so most common patterns are checked
1574 first. This reduces the compilation time in another 5% (from 8.11s
1575 average to 7.73s for bootstrapping mcs on my Mobile p4/1.8ghz).
1577 The parsing time is 22% of the compilation in mcs, and from that
1578 64% is spent on the tokenization process.
1580 I tried using a binary search for keywords, but this is slower
1581 than the hashtable. Another option would be to do a couple of
1584 * Not use a StringBuilder, instead use an array of chars,
1585 with a set value. Notice that this way we could catch
1586 the 645 error without having to do it *afterwards*.
1588 * We could write a hand-parser to avoid the hashtable
1589 compares altogether.
1591 The identifier consumption process takes 37% of the tokenization
1592 time. Another 15% is spent on is_number. 56% of the time spent
1593 on is_number is spent on Int64.Parse:
1595 * We could probably choose based on the string length to
1596 use Int32.Parse or Int64.Parse and avoid all the 64-bit
1599 Another 3% is spend on wrapping `xtoken' in the `token' function.
1601 Handle 0xa0 as whitespace (#34752)
1603 2002-11-26 Miguel de Icaza <miguel@ximian.com>
1605 * typemanager.cs (IsCLRType): New routine to tell whether a type
1606 is one of the builtin types.
1608 Maybe it needs to use TypeCodes to be faster. Maybe we could use
1609 typecode in more places instead of doing pointer comparissions.
1610 We could leverage some knowledge about the way the typecodes are
1613 New code to cache namespaces in assemblies, it is currently not
1614 invoked, to be used soon.
1616 * decl.cs (DeclSpace.MakeFQN): Simple optimization.
1618 * expression.cs (Binary.ResolveOperator): specially handle
1619 strings, and do not perform user-defined operator overloading for
1622 2002-11-24 Miguel de Icaza <miguel@ximian.com>
1624 * cs-tokenizer.cs: Avoid calling Char.IsDigit which is an
1625 internalcall as it is a pretty simple operation; Avoid whenever
1626 possible to call Char.IsLetter.
1628 (consume_identifier): Cut by half the number of
1629 hashtable calls by merging the is_keyword and GetKeyword behavior.
1631 Do not short-circuit, because if we do, we
1632 report errors (ie, #if false && true would produce an invalid
1636 2002-11-24 Martin Baulig <martin@ximian.com>
1638 * expression.cs (Cast.TryReduce): If we're in checked syntax,
1639 check constant ranges and report a CS0221. Fixes #33186.
1641 2002-11-24 Martin Baulig <martin@ximian.com>
1643 * cs-parser.jay: Make this work for uninitialized variable
1644 declarations in the `for' initializer. Fixes #32416.
1646 2002-11-24 Martin Baulig <martin@ximian.com>
1648 * ecore.cs (Expression.ConvertExplicit): Make casting from/to
1649 System.Enum actually work. Fixes bug #32269, added verify-6.cs.
1651 2002-11-24 Martin Baulig <martin@ximian.com>
1653 * expression.cs (Binary.DoNumericPromotions): Added `check_user_conv'
1654 argument; if true, we also check for user-defined conversions.
1655 This is only needed if both arguments are of a user-defined type.
1656 Fixes #30443, added test-175.cs.
1657 (Binary.ForceConversion): Pass the location argument to ConvertImplicit.
1659 * ecore.cs (Expression.ImplicitUserConversionExists): New method.
1661 2002-11-24 Martin Baulig <martin@ximian.com>
1663 * expression.cs (ArrayAccess.GetStoreOpcode): New public static
1664 function to get the store opcode.
1665 (Invocation.EmitParams): Call ArrayAccess.GetStoreOpcode() and
1666 only emit the Ldelema if the store opcode is Stobj. You must run
1667 both test-34 and test-167 to test this. Fixes #34529.
1669 2002-11-23 Martin Baulig <martin@ximian.com>
1671 * ecore.cs (Expression.MemberLookup): Added additional
1672 `qualifier_type' argument which is used when we're being called
1673 from MemberAccess.DoResolve() and null if we're called from a
1675 (Expression.MemberLookupFailed): New method to report errors; this
1676 does the CS1540 check and reports the correct error message.
1678 * typemanager.cs (MemberLookup): Added additional `qualifier_type'
1679 argument for the CS1540 check and redone the way how we're dealing
1680 with private members. See the comment in the source code for details.
1681 (FilterWithClosure): Reverted this back to revision 1.197; renamed
1682 `closure_start_type' to `closure_qualifier_type' and check whether
1683 it's not null. It was not this filter being broken, it was just
1684 being called with the wrong arguments.
1686 * expression.cs (MemberAccess.DoResolve): use MemberLookupFinal()
1687 and pass it the correct `qualifier_type'; this also does the error
1690 2002-11-22 Miguel de Icaza <miguel@ximian.com>
1692 * expression.cs (Invocation.EmitParams): If the we are dealing
1693 with a non-built-in value type, load its address as well.
1695 (ArrayCreation): Use a a pretty constant instead
1696 of the hardcoded value 2. Use 6 instead of 2 for the number of
1697 static initializers.
1699 (ArrayCreation.EmitDynamicInitializers): Peel enumerations,
1700 because they are not really value types, just glorified integers.
1702 * driver.cs: Do not append .exe, the CSC compiler does not do it.
1704 * ecore.cs: Remove redundant code for enumerations, make them use
1705 the same code path as everything else, fixes the casting issue
1706 with enumerations in Windows.Forms.
1708 * attribute.cs: Do only cast to string if it is a string, the
1709 validation happens later.
1711 * typemanager.cs: Temproary hack to avoid a bootstrap issue until
1712 people upgrade their corlibs.
1714 * ecore.cs: Oops, enumerations were not following the entire code path
1716 2002-11-21 Miguel de Icaza <miguel@ximian.com>
1718 * typemanager.cs (FilterWithClosure): Commented out the test for
1719 1540 in typemanager.cs, as it has problems when accessing
1720 protected methods from a parent class (see test-174.cs).
1722 * attribute.cs (Attribute.ValidateGuid): new method.
1723 (Attribute.Resolve): Use above.
1725 2002-11-19 Miguel de Icaza <miguel@ximian.com>
1727 * enum.cs: In FindMembers, perform a recursive lookup for values. (34308)
1729 * ecore.cs (SimpleName.SimpleNameResolve): Remove the special
1730 handling for enumerations, as we only needed the TypeContainer
1731 functionality to begin with (this is required for the fix below to
1732 work for enums that reference constants in a container class for
1735 * codegen.cs (EmitContext): Make TypeContainer a DeclSpace.
1737 * enum.cs (Enum.Define): Use `this' instead of parent, so we have
1738 a valid TypeBuilder to perform lookups on.o
1740 * class.cs (InheritableMemberSignatureCompare): Use true in the
1741 call to GetGetMethod and GetSetMethod, because we are comparing
1742 the signature, and we need to get the methods *even* if they are
1745 (PropertyBase.CheckBase): ditto.
1747 * statement.cs (Switch.ResolveAndReduce, Block.EmitMeta,
1748 GotoCase.Resolve): Use Peel on EmpytCasts.
1750 * ecore.cs (EmptyCast): drop child, add Peel method.
1752 2002-11-17 Martin Baulig <martin@ximian.com>
1754 * ecore.cs (EmptyCast.Child): New public property.
1756 * statement.cs (SwitchLabel.ResolveAndReduce): Check whether the
1757 label resolved to an EmptyCast. Fixes #34162.
1758 (GotoCase.Resolve): Likewise.
1759 (Block.EmitMeta): Likewise.
1761 2002-11-17 Martin Baulig <martin@ximian.com>
1763 * expression.cs (Invocation.BetterConversion): Prefer int over
1764 uint; short over ushort; long over ulong for integer literals.
1765 Use ImplicitConversionExists instead of StandardConversionExists
1766 since we also need to check for user-defined implicit conversions.
1767 Fixes #34165. Added test-173.cs.
1769 2002-11-16 Martin Baulig <martin@ximian.com>
1771 * expression.cs (Binary.EmitBranchable): Eliminate comparisions
1772 with the `true' and `false' literals. Fixes #33151.
1774 2002-11-16 Martin Baulig <martin@ximian.com>
1776 * typemanager.cs (RealMemberLookup): Reverted Miguel's patch from
1777 October 22nd; don't do the cs1540 check for static members.
1779 * ecore.cs (PropertyExpr.ResolveAccessors): Rewrote this; we're
1780 now using our own filter here and doing the cs1540 check again.
1782 2002-11-16 Martin Baulig <martin@ximian.com>
1784 * support.cs (InternalParameters): Don't crash if we don't have
1785 any fixed parameters. Fixes #33532.
1787 2002-11-16 Martin Baulig <martin@ximian.com>
1789 * decl.cs (MemberCache.AddMethods): Use BindingFlags.FlattenHierarchy
1790 when looking up static methods to make this work on Windows.
1793 2002-11-16 Martin Baulig <martin@ximian.com>
1795 * ecore.cs (PropertyExpr.VerifyAssignable): Check whether we have
1796 a setter rather than using PropertyInfo.CanWrite.
1798 2002-11-15 Nick Drochak <ndrochak@gol.com>
1800 * class.cs: Allow acces to block member by subclasses. Fixes build
1803 2002-11-14 Martin Baulig <martin@ximian.com>
1805 * class.cs (Constructor.Emit): Added the extern/block check.
1808 2002-11-14 Martin Baulig <martin@ximian.com>
1810 * expression.cs (IndexerAccess.DoResolve): Do a DeclaredOnly
1811 iteration while looking for indexers, this is needed because the
1812 indexer may have a different name in our base classes. Fixed the
1813 error reporting (no indexers at all, not get accessor, no
1814 overloaded match). Fixes bug #33089.
1815 (IndexerAccess.DoResolveLValue): Likewise.
1817 2002-11-14 Martin Baulig <martin@ximian.com>
1819 * class.cs (PropertyBase.CheckBase): Make this work for multiple
1820 indexers. Fixes the first part of bug #33089.
1821 (MethodSignature.InheritableMemberSignatureCompare): Added support
1824 2002-11-13 Ravi Pratap <ravi@ximian.com>
1826 * attribute.cs (Attribute.Resolve): Catch the
1827 NullReferenceException and report it since it isn't supposed to
1830 2002-11-12 Miguel de Icaza <miguel@ximian.com>
1832 * expression.cs (Binary.EmitBranchable): Also handle the cases for
1833 LogicalOr and LogicalAnd that can benefit from recursively
1834 handling EmitBranchable. The code now should be nice for Paolo.
1836 2002-11-08 Miguel de Icaza <miguel@ximian.com>
1838 * typemanager.cs (LookupType): Added a negative-hit hashtable for
1839 the Type lookups, as we perform quite a number of lookups on
1840 non-Types. This can be removed once we can deterministically tell
1841 whether we have a type or a namespace in advance.
1843 But this might require special hacks from our corlib.
1847 * ecore.cs (TryImplicitIntConversion): Handle conversions to float
1848 and double which avoids a conversion from an integer to a double.
1850 * expression.cs: tiny optimization, avoid calling IsConstant,
1851 because it effectively performs the lookup twice.
1853 2002-11-06 Miguel de Icaza <miguel@ximian.com>
1855 But a bogus return here to keep the semantics of the old code
1856 until the Mono runtime is fixed.
1858 * pending.cs (GetMissingInterfaces): New method used to remove all
1859 the interfaces that are already implemented by our parent
1860 classes from the list of pending methods.
1862 * interface.cs: Add checks for calls after ResolveTypeExpr.
1864 2002-11-05 Miguel de Icaza <miguel@ximian.com>
1866 * class.cs (Class.Emit): Report warning 67: event not used if the
1867 warning level is beyond 3.
1869 * ecore.cs (Expression.ConvertExplicit): Missed a check for expr
1870 being a NullLiteral.
1872 * cs-parser.jay: Fix, Gonzalo reverted the order of the rank
1875 * class.cs (TypeContainer.GetClassBases): Cover a missing code
1876 path that might fail if a type can not be resolved.
1878 * expression.cs (Binary.Emit): Emit unsigned versions of the
1881 * driver.cs: use error 5.
1883 2002-11-02 Gonzalo Paniagua Javier <gonzalo@gnome-db.org>
1885 * cs-parser.jay: simplified a rule and 5 SR conflicts dissapeared.
1887 2002-11-01 Miguel de Icaza <miguel@ximian.com>
1889 * cs-parser.jay (switch_section): A beautiful patch from Martin
1890 Baulig that fixed 33094.
1892 2002-10-31 Miguel de Icaza <miguel@ximian.com>
1894 * ecore.cs (PropertyExpr.DoResolveLValue, PropertyExpr.DoResolve):
1895 Check whether the base is abstract and report an error if so.
1897 * expression.cs (IndexerAccess.DoResolveLValue,
1898 IndexerAccess.DoResolve): ditto.
1900 (Invocation.DoResolve): ditto.
1902 (Invocation.FullMethodDesc): Improve the report string.
1904 * statement.cs (Block): Eliminate IsVariableDefined as it is
1905 basically just a wrapper for GetVariableInfo.
1907 * ecore.cs (SimpleName): Use new
1909 * support.cs (ReflectionParamter.ParameterType): We unwrap the
1910 type, as we return the actual parameter ref/unref state on a
1913 2002-10-30 Miguel de Icaza <miguel@ximian.com>
1915 * support.cs: Return proper flags REF/OUT fixing the previous
1918 * expression.cs: Reverted last patch, that was wrong. Is_ref is
1919 not used to mean `ref' but `ref or out' in ParameterReference
1921 * delegate.cs (FullDelegateDesc): use ParameterDesc to get the
1922 full type signature instead of calling TypeManger.CSharpName
1925 * support.cs (InternalParameters.ParameterDesc): Do not compare
1926 directly to the modflags, because REF/OUT will actually be bitsets
1929 * delegate.cs (VerifyMethod): Check also the modifiers.
1931 * cs-tokenizer.cs: Fix bug where floating point values with an
1932 exponent where a sign was missing was ignored.
1934 * driver.cs: Allow multiple assemblies to be specified in a single
1937 2002-10-28 Miguel de Icaza <miguel@ximian.com>
1939 * cs-parser.jay: Ugly. We had to add a multiplicative_expression,
1940 because identifiers after a parenthesis would end up in this kind
1941 of production, and we needed to desamiguate it for having casts
1944 (UserDefinedType *) xxx
1946 2002-10-24 Miguel de Icaza <miguel@ximian.com>
1948 * typemanager.cs (RealMemberLookup): when we deal with a subclass,
1949 we should set on the Bindingflags.NonPublic, but not turn on
1950 private_ok. private_ok controls whether a Private member is
1951 returned (this is chekced on the filter routine), while the
1952 BindingFlags.NonPublic just controls whether private/protected
1953 will be allowed. This fixes the problem part of the problem of
1954 private properties being allowed to be used in derived classes.
1956 * expression.cs (BaseAccess): Provide an DoResolveLValue method,
1957 so we can call the children DoResolveLValue method (this will
1958 properly signal errors on lvalue assignments to base properties)
1960 * ecore.cs (PropertyExpr.ResolveAccessors): If both setter and
1961 getter are null, and we have a property info, we know that this
1962 happened because the lookup failed, so we report an error 122 for
1963 protection level violation.
1965 We also silently return if setter and getter are null in the
1966 resolve functions, this condition only happens if we have flagged
1967 the error before. This is the other half of the problem.
1969 (PropertyExpr.ResolveAccessors): Turns out that PropertyInfo does
1970 not have accessibility information, that is why we were returning
1971 true in the filter function in typemanager.cs.
1973 To properly report 122 (property is inaccessible because of its
1974 protection level) correctly, we report this error in ResolveAccess
1975 by failing if both the setter and the getter are lacking (ie, the
1978 DoResolve and DoLResolve have been modified to check for both
1979 setter/getter being null and returning silently, the reason being
1980 that I did not want to put the knowledge about this error in upper
1983 int old = Report.Errors;
1984 x = new PropertyExpr (...);
1985 if (old != Report.Errors)
1990 So the property expr is returned, but it is invalid, so the error
1991 will be flagged during the resolve process.
1993 * class.cs: Remove InheritablePropertySignatureCompare from the
1994 class, as we no longer depend on the property signature to compute
1995 whether it is possible to implement a method or not.
1997 The reason is that calling PropertyInfo.GetGetMethod will return
1998 null (in .NET, in Mono it works, and we should change this), in
1999 cases where the Get Method does not exist in that particular
2004 class X { public virtual int A { get { return 1; } } }
2006 class Z : Y { public override int A { get { return 2; } } }
2008 Would fail in Z because the parent (Y) would not have the property
2009 defined. So we avoid this completely now (because the alternative
2010 fix was ugly and slow), and we now depend exclusively on the
2013 (PropertyBase.CheckBase): Use a method-base mechanism to find our
2014 reference method, instead of using the property.
2016 * typemanager.cs (GetPropertyGetter, GetPropertySetter): These
2017 routines are gone now.
2019 * typemanager.cs (GetPropertyGetter, GetPropertySetter): swap the
2020 names, they were incorrectly named.
2022 * cs-tokenizer.cs: Return are more gentle token on failure.
2024 * pending.cs (PendingImplementation.InterfaceMethod): This routine
2025 had an out-of-sync index variable, which caused it to remove from
2026 the list of pending methods the wrong method sometimes.
2028 2002-10-22 Miguel de Icaza <miguel@ximian.com>
2030 * ecore.cs (PropertyExpr): Do not use PropertyInfo.CanRead,
2031 CanWrite, because those refer to this particular instance of the
2032 property, and do not take into account the fact that we can
2033 override single members of a property.
2035 Constructor requires an EmitContext. The resolution process does
2036 not happen here, but we need to compute the accessors before,
2037 because the resolution does not always happen for properties.
2039 * typemanager.cs (RealMemberLookup): Set private_ok if we are a
2040 subclass, before we did not update this flag, but we did update
2043 (GetAccessors): Drop this routine, as it did not work in the
2044 presence of partially overwritten set/get methods.
2046 Notice that this broke the cs1540 detection, but that will require
2049 2002-10-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2053 * driver.cs: issue a warning instead of an error if we don't support
2054 debugging for the platform. Also ignore a couple of errors that may
2055 arise when trying to write the symbols. Undo my previous patch.
2057 2002-10-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2059 * driver.cs: ignore /debug switch except for Unix platforms.
2061 2002-10-23 Nick Drochak <ndrochak@gol.com>
2063 * makefile: Remove mcs2.exe and mcs3.exe on 'make clean'
2065 2002-10-21 Miguel de Icaza <miguel@ximian.com>
2067 * driver.cs: Do not make mcs-debug conditional, so we do not break
2070 * statement.cs (UsageVector.MergeChildren): I would like Martin to
2071 review this patch. But basically after all the children variables
2072 have been merged, the value of "Breaks" was not being set to
2073 new_breaks for Switch blocks. I think that it should be set after
2074 it has executed. Currently I set this to the value of new_breaks,
2075 but only if new_breaks is FlowReturn.ALWAYS, which is a bit
2076 conservative, but I do not understand this code very well.
2078 I did not break anything in the build, so that is good ;-)
2080 * cs-tokenizer.cs: Also allow \r in comments as a line separator.
2082 2002-10-20 Mark Crichton <crichton@gimp.org>
2084 * cfold.cs: Fixed compile blocker. Really fixed it this time.
2086 2002-10-20 Nick Drochak <ndrochak@gol.com>
2088 * cfold.cs: Fixed compile blocker.
2090 2002-10-20 Miguel de Icaza <miguel@ximian.com>
2092 * driver.cs: I was chekcing the key, not the file.
2094 2002-10-19 Ravi Pratap <ravi@ximian.com>
2096 * ecore.cs (UserDefinedConversion): Get rid of the bogus error
2097 message that we were generating - we just need to silently return
2100 2002-10-19 Miguel de Icaza <miguel@ximian.com>
2102 * class.cs (Event.Define): Change my previous commit, as this
2103 breaks the debugger. This is a temporary hack, as it seems like
2104 the compiler is generating events incorrectly to begin with.
2106 * expression.cs (Binary.ResolveOperator): Added support for
2107 "U operator - (E x, E y)"
2109 * cfold.cs (BinaryFold): Added support for "U operator - (E x, E
2112 * ecore.cs (FieldExpr.AddressOf): We had a special code path for
2113 init-only variables, but this path did not take into account that
2114 there might be also instance readonly variables. Correct this
2117 This fixes bug 32253
2119 * delegate.cs (NewDelegate.DoResolve): Catch creation of unsafe
2122 * driver.cs: Change the extension for modules to `netmodule'
2124 * cs-parser.jay: Improved slightly the location tracking for
2125 the debugger symbols.
2127 * class.cs (Event.Define): Use Modifiers.FieldAttr on the
2128 modifiers that were specified instead of the hardcoded value
2129 (FamAndAssem). This was basically ignoring the static modifier,
2130 and others. Fixes 32429.
2132 * statement.cs (Switch.SimpleSwitchEmit): Simplified the code, and
2133 fixed a bug in the process (32476)
2135 * expression.cs (ArrayAccess.EmitAssign): Patch from
2136 hwang_rob@yahoo.ca that fixes bug 31834.3
2138 2002-10-18 Miguel de Icaza <miguel@ximian.com>
2140 * driver.cs: Make the module extension .netmodule.
2142 2002-10-16 Miguel de Icaza <miguel@ximian.com>
2144 * driver.cs: Report an error if the resource file is not found
2145 instead of crashing.
2147 * ecore.cs (PropertyExpr.EmitAssign): Pass IsBase instead of
2148 false, like Emit does.
2150 2002-10-16 Nick Drochak <ndrochak@gol.com>
2152 * typemanager.cs: Remove unused private member. Also reported mcs
2153 bug to report this as a warning like csc.
2155 2002-10-15 Martin Baulig <martin@gnome.org>
2157 * statement.cs (Statement.Emit): Made this a virtual method; emits
2158 the line number info and calls DoEmit().
2159 (Statement.DoEmit): New protected abstract method, formerly knows
2160 as Statement.Emit().
2162 * codegen.cs (EmitContext.Mark): Check whether we have a symbol writer.
2164 2002-10-11 Miguel de Icaza <miguel@ximian.com>
2166 * class.cs: Following the comment from 2002-09-26 to AddMethod, I
2167 have fixed a remaining problem: not every AddXXXX was adding a
2168 fully qualified name.
2170 Now everyone registers a fully qualified name in the DeclSpace as
2171 being defined instead of the partial name.
2173 Downsides: we are slower than we need to be due to the excess
2174 copies and the names being registered this way.
2176 The reason for this is that we currently depend (on the corlib
2177 bootstrap for instance) that types are fully qualified, because
2178 we dump all the types in the namespace, and we should really have
2179 types inserted into the proper namespace, so we can only store the
2180 basenames in the defined_names array.
2182 2002-10-10 Martin Baulig <martin@gnome.org>
2184 * expression.cs (ArrayAccess.EmitStoreOpcode): Reverted the patch
2185 from bug #31834, see the bug report for a testcase which is
2188 2002-10-10 Martin Baulig <martin@gnome.org>
2190 * codegen.cs (EmitContext.Breaks): Removed, we're now using the
2191 flow analysis code for this.
2193 * statement.cs (Do, While, For): Tell the flow analysis code about
2195 (FlowBranching.UsageVector): Added support for infinite loops.
2196 (Block.Resolve): Moved the dead code elimination here and use flow
2199 2002-10-09 Miguel de Icaza <miguel@ximian.com>
2201 * class.cs (Field.Define): Catch cycles on struct type
2204 * typemanager.cs (IsUnmanagedtype): Do not recursively check
2205 fields if the fields are static. We only need to check instance
2208 * expression.cs (As.DoResolve): Test for reference type.
2210 * statement.cs (Using.ResolveExpression): Use
2211 ConvertImplicitRequired, not ConvertImplicit which reports an
2213 (Using.ResolveLocalVariableDecls): ditto.
2215 * expression.cs (Binary.ResolveOperator): Report errors in a few
2216 places where we had to.
2218 * typemanager.cs (IsUnmanagedtype): Finish implementation.
2220 2002-10-08 Miguel de Icaza <miguel@ximian.com>
2222 * expression.cs: Use StoreFromPtr instead of extracting the type
2223 and then trying to use Stelem. Patch is from hwang_rob@yahoo.ca
2225 * ecore.cs (ImplicitReferenceConversion): It is possible to assign
2226 an enumeration value to a System.Enum, but System.Enum is not a
2227 value type, but an class type, so we need to box.
2229 (Expression.ConvertExplicit): One codepath could return
2230 errors but not flag them. Fix this. Fixes #31853
2232 * parameter.cs (Resolve): Do not allow void as a parameter type.
2234 2002-10-06 Martin Baulig <martin@gnome.org>
2236 * statemenc.cs (FlowBranching.SetParameterAssigned): Don't crash
2237 if it's a class type and not a struct. Fixes #31815.
2239 2002-10-06 Martin Baulig <martin@gnome.org>
2241 * statement.cs: Reworked the flow analysis code a bit to make it
2242 usable for dead code elimination.
2244 2002-10-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2246 * cs-parser.jay: allow empty source files. Fixes bug #31781.
2248 2002-10-04 Miguel de Icaza <miguel@ximian.com>
2250 * expression.cs (ComposedCast.DoResolveType): A quick workaround
2251 to fix the test 165, will investigate deeper.
2253 2002-10-04 Martin Baulig <martin@gnome.org>
2255 * statement.cs (FlowBranching.UsageVector.MergeChildren): Make
2256 finally blocks actually work.
2257 (Try.Resolve): We don't need to create a sibling for `finally' if
2258 there is no finally block.
2260 2002-10-04 Martin Baulig <martin@gnome.org>
2262 * class.cs (Constructor.Define): The default accessibility for a
2263 non-default constructor is private, not public.
2265 2002-10-04 Miguel de Icaza <miguel@ximian.com>
2267 * class.cs (Constructor): Make AllowedModifiers public, add
2270 * cs-parser.jay: Perform the modifiers test here, as the
2271 constructor for the Constructor class usually receives a zero
2272 because of the way we create it (first we create, later we
2273 customize, and we were never checking the modifiers).
2275 * typemanager.cs (Typemanager.LookupTypeDirect): This new function
2276 is a version of LookupTypeReflection that includes the type-name
2277 cache. This can be used as a fast path for functions that know
2278 the fully qualified name and are only calling into *.GetType() to
2279 obtain a composed type.
2281 This is also used by TypeManager.LookupType during its type
2284 (LookupType): We now also track the real type name, as sometimes
2285 we can get a quey for the real type name from things like
2286 ComposedCast. This fixes bug 31422.
2288 * expression.cs (ComposedCast.Resolve): Since we are obtaining a
2289 complete type fullname, it does not have to go through the type
2290 resolution system to obtain the composed version of the type (for
2291 obtaining arrays or pointers).
2293 (Conditional.Emit): Use the EmitBoolExpression to
2294 generate nicer code, as requested by Paolo.
2296 (ArrayCreation.CheckIndices): Use the patch from
2297 hwang_rob@yahoo.ca to validate the array initializers.
2299 2002-10-03 Miguel de Icaza <miguel@ximian.com>
2301 * class.cs (ConstructorInitializer.Emit): simplify code by using
2302 Invocation.EmitCall, and at the same time, fix the bugs in calling
2303 parent constructors that took variable arguments.
2305 * ecore.cs (Expression.ConvertNumericExplicit,
2306 Expression.ImplicitNumericConversion): Remove the code that
2307 manually wrapped decimal (InternalTypeConstructor call is now gone
2310 * expression.cs (Cast.TryReduce): Also handle decimal types when
2311 trying to perform a constant fold on the type.
2313 * typemanager.cs (IsUnmanagedtype): Partially implemented.
2315 * parameter.cs: Removed ResolveAndDefine, as it was not needed, as
2316 that only turned off an error report, and did nothing else.
2318 2002-10-02 Miguel de Icaza <miguel@ximian.com>
2320 * driver.cs: Handle and ignore /fullpaths
2322 2002-10-01 Miguel de Icaza <miguel@ximian.com>
2324 * expression.cs (Binary.ResolveOperator): Catch the case where
2325 DoNumericPromotions returns true,
2327 (Binary.DoNumericPromotions): Simplify the code, and the tests.
2329 2002-09-27 Miguel de Icaza <miguel@ximian.com>
2331 * ecore.cs (EventExpr.Emit): Instead of emitting an exception,
2334 2002-09-26 Miguel de Icaza <miguel@ximian.com>
2336 * ecore.cs (ConvertNumericExplicit): It is not enough that the
2337 conversion exists, but it is also required that the conversion be
2338 performed. This manifested in "(Type64Enum) 2".
2340 * class.cs (TypeManager.AddMethod): The fix is not to change
2341 AddEnum, because that one was using a fully qualified name (every
2342 DeclSpace derivative does), but to change the AddMethod routine
2343 that was using an un-namespaced name. This now correctly reports
2344 the duplicated name.
2346 Revert patch until I can properly fix it. The issue
2347 is that we have a shared Type space across all namespaces
2348 currently, which is wrong.
2350 Options include making the Namespace a DeclSpace, and merge
2351 current_namespace/current_container in the parser.
2353 2002-09-25 Miguel de Icaza <miguel@ximian.com>
2355 * cs-parser.jay: Improve error reporting when we get a different
2356 kind of expression in local_variable_type and
2357 local_variable_pointer_type.
2359 Propagate this to avoid missleading errors being reported.
2361 * ecore.cs (ImplicitReferenceConversion): treat
2362 TypeManager.value_type as a target just like object_type. As
2367 Is valid, and needs to result in the int 1 being boxed before it
2368 is assigned to the value type v.
2370 * class.cs (TypeContainer.AddEnum): Use the basename, not the name
2371 to validate the enumeration name.
2373 * expression.cs (ArrayAccess.EmitAssign): Mimic the same test from
2374 EmitDynamicInitializers for the criteria to use Ldelema. Thanks
2375 to hwang_rob@yahoo.ca for finding the bug and providing a patch.
2377 * ecore.cs (TryImplicitIntConversion): When doing an
2378 implicit-enumeration-conversion, check if the type is 64-bits and
2379 perform a conversion before passing to EnumConstant.
2381 2002-09-23 Miguel de Icaza <miguel@ximian.com>
2383 * decl.cs (Error_AmbiguousTypeReference); New routine used to
2384 report ambiguous type references. Unlike the MS version, we
2385 report what the ambiguity is. Innovation at work ;-)
2387 (DeclSpace.FindType): Require a location argument to
2388 display when we display an ambiguous error.
2390 * ecore.cs: (SimpleName.DoResolveType): Pass location to FindType.
2392 * interface.cs (GetInterfaceTypeByName): Pass location to FindType.
2394 * expression.cs (EmitDynamicInitializers): Apply patch from
2395 hwang_rob@yahoo.ca that fixes the order in which we emit our
2398 2002-09-21 Martin Baulig <martin@gnome.org>
2400 * delegate.cs (Delegate.VerifyApplicability): Make this work if the
2401 delegate takes no arguments.
2403 2002-09-20 Miguel de Icaza <miguel@ximian.com>
2405 * constant.cs: Use Conv_U8 instead of Conv_I8 when loading longs
2408 * expression.cs: Extract the underlying type.
2410 * ecore.cs (StoreFromPtr): Use TypeManager.IsEnumType instad of IsEnum
2412 * decl.cs (FindType): Sorry about this, fixed the type lookup bug.
2414 2002-09-19 Miguel de Icaza <miguel@ximian.com>
2416 * class.cs (TypeContainer.DefineType): We can not use the nice
2417 PackingSize with the size set to 1 DefineType method, because it
2418 will not allow us to define the interfaces that the struct
2421 This completes the fixing of bug 27287
2423 * ecore.cs (Expresion.ImplicitReferenceConversion): `class-type S'
2424 means also structs. This fixes part of the problem.
2425 (Expresion.ImplicitReferenceConversionExists): ditto.
2427 * decl.cs (DeclSparce.ResolveType): Only report the type-not-found
2428 error if there were no errors reported during the type lookup
2429 process, to avoid duplicates or redundant errors. Without this
2430 you would get an ambiguous errors plus a type not found. We have
2431 beaten the user enough with the first error.
2433 (DeclSparce.FindType): Emit a warning if we have an ambiguous
2436 * ecore.cs (SimpleName.DoResolveType): If an error is emitted
2437 during the resolution process, stop the lookup, this avoids
2438 repeated error reports (same error twice).
2440 * rootcontext.cs: Emit a warning if we have an ambiguous reference.
2442 * typemanager.cs (LookupType): Redo the type lookup code to match
2443 the needs of System.Reflection.
2445 The issue is that System.Reflection requires references to nested
2446 types to begin with a "+" sign instead of a dot. So toplevel
2447 types look like: "NameSpace.TopLevelClass", and nested ones look
2448 like "Namespace.TopLevelClass+Nested", with arbitrary nesting
2451 2002-09-19 Martin Baulig <martin@gnome.org>
2453 * codegen.cs (EmitContext.EmitTopBlock): If control flow analysis
2454 says that a method always returns or always throws an exception,
2455 don't report the CS0161.
2457 * statement.cs (FlowBranching.UsageVector.MergeChildren): Always
2458 set `Returns = new_returns'.
2460 2002-09-19 Martin Baulig <martin@gnome.org>
2462 * expression.cs (MemberAccess.ResolveMemberAccess): When resolving
2463 to an enum constant, check for a CS0176.
2465 2002-09-18 Miguel de Icaza <miguel@ximian.com>
2467 * class.cs (TypeContainer.CheckPairedOperators): Now we check
2468 for operators that must be in pairs and report errors.
2470 * ecore.cs (SimpleName.DoResolveType): During the initial type
2471 resolution process, when we define types recursively, we must
2472 check first for types in our current scope before we perform
2473 lookups in the enclosing scopes.
2475 * expression.cs (MakeByteBlob): Handle Decimal blobs.
2477 (Invocation.VerifyArgumentsCompat): Call
2478 TypeManager.TypeToCoreType on the parameter_type.GetElementType.
2479 I thought we were supposed to always call this, but there are a
2480 few places in the code where we dont do it.
2482 2002-09-17 Miguel de Icaza <miguel@ximian.com>
2484 * driver.cs: Add support in -linkres and -resource to specify the
2485 name of the identifier.
2487 2002-09-16 Miguel de Icaza <miguel@ximian.com>
2489 * ecore.cs (StandardConversionExists): Sync with the conversion
2490 code: allow anything-* to void* conversions.
2492 (FindMostSpecificSource): Use an Expression argument
2493 instead of a Type, because we might be handed over a Literal which
2494 gets a few more implicit conversions that plain types do not. So
2495 this information was being lost.
2497 Also, we drop the temporary type-holder expression when not
2500 2002-09-17 Martin Baulig <martin@gnome.org>
2502 * class.cs (PropertyBase.CheckBase): Don't check the base class if
2503 this is an explicit interface implementation.
2505 2002-09-17 Martin Baulig <martin@gnome.org>
2507 * class.cs (PropertyBase.CheckBase): Make this work for indexers with
2508 different `IndexerName' attributes.
2510 * expression.cs (BaseIndexerAccess): Rewrote this class to use IndexerAccess.
2511 (IndexerAccess): Added special protected ctor for BaseIndexerAccess and
2512 virtual CommonResolve().
2514 2002-09-16 Miguel de Icaza <miguel@ximian.com>
2516 * enum.cs (LookupEnumValue): Use the EnumConstant declared type,
2517 and convert that to the UnderlyingType.
2519 * statement.cs (Foreach.Resolve): Indexers are just like variables
2520 or PropertyAccesses.
2522 * cs-tokenizer.cs (consume_string): Track line numbers and columns
2523 inside quoted strings, we were not doing this before.
2525 2002-09-16 Martin Baulig <martin@gnome.org>
2527 * ecore.cs (MethodGroupExpr.DoResolve): If we have an instance expression,
2528 resolve it. This is needed for the definite assignment check of the
2529 instance expression, fixes bug #29846.
2530 (PropertyExpr.DoResolve, EventExpr.DoResolve): Likewise.
2532 2002-09-16 Nick Drochak <ndrochak@gol.com>
2534 * parameter.cs: Fix compile error. Cannot reference static member
2535 from an instance object. Is this an mcs bug?
2537 2002-09-14 Martin Baulig <martin@gnome.org>
2539 * decl.cs (MemberCache.SetupCacheForInterface): Don't add an interface
2540 multiple times. Fixes bug #30295, added test-166.cs.
2542 2002-09-14 Martin Baulig <martin@gnome.org>
2544 * statement.cs (Block.Emit): Don't emit unreachable code.
2545 (Switch.SimpleSwitchEmit, Switch.TableSwitchEmit): Check for missing
2547 (Goto.Emit, Continue.Emit): Set ec.Breaks = true.
2549 2002-09-14 Martin Baulig <martin@gnome.org>
2551 * parameter.cs (Parameter.Attributes): Make this work if Modifier.ISBYREF
2554 2002-09-14 Martin Baulig <martin@gnome.org>
2556 * typemanager.cs (TypeManager.IsNestedChildOf): This must return false
2557 if `type == parent' since in this case `type.IsSubclassOf (parent)' will
2558 be false on the ms runtime.
2560 2002-09-13 Martin Baulig <martin@gnome.org>
2562 * ecore.cs (SimpleName.SimpleNameResolve): Include the member name in
2563 the CS0038 error message.
2565 2002-09-12 Miguel de Icaza <miguel@ximian.com>
2567 * expression.cs (CheckedExpr, UnCheckedExpr): If we have a
2568 constant inside, return it.
2570 2002-09-12 Martin Baulig <martin@gnome.org>
2572 * cfold.cs (ConstantFold.DoConstantNumericPromotions): Check whether an
2573 implicit conversion can be done between enum types.
2575 * enum.cs (Enum.LookupEnumValue): If the value is an EnumConstant,
2576 check whether an implicit conversion to the current enum's UnderlyingType
2577 exists and report an error if not.
2579 * codegen.cs (CodeGen.Init): Delete the symbol file when compiling
2580 without debugging support.
2582 * delegate.cs (Delegate.CloseDelegate): Removed, use CloseType instead.
2583 Fixes bug #30235. Thanks to Ricardo Fernández Pascual.
2585 2002-09-12 Martin Baulig <martin@gnome.org>
2587 * typemanager.cs (TypeManager.IsNestedChildOf): New method.
2589 * ecore.cs (IMemberExpr.DeclaringType): New property.
2590 (SimpleName.SimpleNameResolve): Check whether we're accessing a
2591 nonstatic member of an outer type (CS0038).
2593 2002-09-11 Miguel de Icaza <miguel@ximian.com>
2595 * driver.cs: Activate the using-error detector at warning level
2596 4 (at least for MS-compatible APIs).
2598 * namespace.cs (VerifyUsing): Small buglett fix.
2600 * pending.cs (PendingImplementation): pass the container pointer.
2602 * interface.cs (GetMethods): Allow for recursive definition. Long
2603 term, I would like to move every type to support recursive
2604 definitions, not the current ordering mechanism that we have right
2607 The situation is this: Attributes are handled before interfaces,
2608 so we can apply attributes to interfaces. But some attributes
2609 implement interfaces, we will now handle the simple cases
2610 (recursive definitions will just get an error).
2612 * parameter.cs: Only invalidate types at the end if we fail to
2615 2002-09-09 Martin Baulig <martin@gnome.org>
2617 * ecore.cs (PropertyExpr.Emit): Also check for
2618 TypeManager.system_int_array_get_length so this'll also work when
2619 compiling corlib. Fixes #30003.
2621 2002-09-09 Martin Baulig <martin@gnome.org>
2623 * expression.cs (ArrayCreation.MakeByteBlob): Added support for enums
2624 and throw an exception if we can't get the type's size. Fixed #30040,
2627 2002-09-09 Martin Baulig <martin@gnome.org>
2629 * ecore.cs (PropertyExpr.DoResolve): Added check for static properies.
2631 * expression.cs (SizeOf.DoResolve): Sizeof is only allowed in unsafe
2632 context. Fixes bug #30027.
2634 * delegate.cs (NewDelegate.Emit): Use OpCodes.Ldvirtftn for
2635 virtual functions. Fixes bug #30043, added test-164.cs.
2637 2002-09-08 Ravi Pratap <ravi@ximian.com>
2639 * attribute.cs : Fix a small NullRef crash thanks to my stupidity.
2641 2002-09-08 Nick Drochak <ndrochak@gol.com>
2643 * driver.cs: Use an object to get the windows codepage since it's not a
2646 2002-09-08 Miguel de Icaza <miguel@ximian.com>
2648 * statement.cs (For.Emit): for infinite loops (test == null)
2649 return whether there is a break inside, not always "true".
2651 * namespace.cs (UsingEntry): New struct to hold the name of the
2652 using definition, the location where it is defined, and whether it
2653 has been used in a successful type lookup.
2655 * rootcontext.cs (NamespaceLookup): Use UsingEntries instead of
2660 2002-09-06 Ravi Pratap <ravi@ximian.com>
2662 * attribute.cs : Fix incorrect code which relied on catching
2663 a NullReferenceException to detect a null being passed in
2664 where an object was expected.
2666 2002-09-06 Miguel de Icaza <miguel@ximian.com>
2668 * statement.cs (Try): flag the catch variable as assigned
2670 * expression.cs (Cast): Simplified by using ResolveType instead of
2673 * statement.cs (Catch): Fix bug by using ResolveType.
2675 2002-09-06 Ravi Pratap <ravi@ximian.com>
2677 * expression.cs (BetterConversion): Special case for when we have
2678 a NullLiteral as the argument and we have to choose between string
2679 and object types - we choose string the way csc does.
2681 * attribute.cs (Attribute.Resolve): Catch the
2682 NullReferenceException and report error #182 since the Mono
2683 runtime no more has the bug and having this exception raised means
2684 we tried to select a constructor which takes an object and is
2687 2002-09-05 Ravi Pratap <ravi@ximian.com>
2689 * expression.cs (Invocation.OverloadResolve): Flag a nicer error
2690 message (1502, 1503) when we can't locate a method after overload
2691 resolution. This is much more informative and closes the bug
2694 * interface.cs (PopulateMethod): Return if there are no argument
2695 types. Fixes a NullReferenceException bug.
2697 * attribute.cs (Attribute.Resolve): Ensure we allow TypeOf
2698 expressions too. Previously we were checking only in one place for
2699 positional arguments leaving out named arguments.
2701 * ecore.cs (ImplicitNumericConversion): Conversion from underlying
2702 type to the enum type is not allowed. Remove code corresponding to
2705 (ConvertNumericExplicit): Allow explicit conversions from
2706 the underlying type to enum type. This precisely follows the spec
2707 and closes a bug filed by Gonzalo.
2709 2002-09-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2712 * compiler.csproj.user: patch from Adam Chester (achester@bigpond.com).
2714 2002-09-03 Miguel de Icaza <miguel@ximian.com>
2716 * statement.cs (SwitchLabel.ResolveAndReduce): In the string case,
2717 it was important that we stored the right value after the
2718 reduction in `converted'.
2720 2002-09-04 Martin Baulig <martin@gnome.org>
2722 * location.cs (Location.SymbolDocument): Use full pathnames for the
2725 2002-08-30 Miguel de Icaza <miguel@ximian.com>
2727 * expression.cs (ComposedCast): Use DeclSparce.ResolveType instead
2728 of the expression resolve mechanism, because that will catch the
2729 SimpleName error failures.
2731 (Conditional): If we can not resolve the
2732 expression, return, do not crash.
2734 2002-08-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2737 (location): display token name instead of its number.
2739 2002-08-28 Martin Baulig <martin@gnome.org>
2741 * expression.cs (Binary.ResolveOperator): Don't silently return
2742 but return an error if an operator cannot be applied between two
2745 2002-08-28 Martin Baulig <martin@gnome.org>
2747 * class.cs (Constructor.Define): Set the permission attributes
2748 correctly instead of making all constructors public.
2750 2002-08-28 Martin Baulig <martin@gnome.org>
2752 * ecore.cs (Expression.DoResolve): Do a TypeManager.MemberLook
2753 for private members before reporting a CS0103; if we find anything,
2756 2002-08-28 Martin Baulig <martin@gnome.org>
2758 * typemanager.cs (TypeManager.FilterWithClosure): It's not enough
2759 to check whether `closure_start_type == closure_invocation_type',
2760 we also need to check whether `m.DeclaringType == closure_invocation_type'
2761 before bypassing the permission checks. We might be accessing
2762 protected/private members from the base class.
2763 (TypeManager.RealMemberLookup): Only set private_ok if private
2764 members were requested via BindingFlags.NonPublic.
2766 * ecore.cs (MethodGroupExpr.IsExplicitImpl): New property.
2768 * expression.cs (MemberAccess.ResolveMemberAccess): Set
2769 MethodGroupExpr.IsExplicitImpl if appropriate.
2770 (Invocation.DoResolve): Don't report the CS0120 for explicit
2771 interface implementations.
2773 2002-08-27 Martin Baulig <martin@gnome.org>
2775 * expression.cs (Invocation.DoResolve): If this is a static
2776 method and we don't have an InstanceExpression, we must report
2779 2002-08-25 Martin Baulig <martin@gnome.org>
2781 * expression.cs (Binary.ResolveOperator): Don't allow `!=' and
2782 `==' between a valuetype and an object.
2784 2002-08-25 Miguel de Icaza <miguel@ximian.com>
2786 * ecore.cs (TypeExpr): Provide a ToString method.
2788 2002-08-24 Martin Baulig <martin@gnome.org>
2790 * codegen.cs (CodeGen.InitMonoSymbolWriter): The symbol file is
2791 now called proggie.dbg and it's a binary file.
2793 2002-08-23 Martin Baulig <martin@gnome.org>
2795 * decl.cs (MemberCache.AddMethods): Ignore varargs methods.
2797 2002-08-23 Martin Baulig <martin@gnome.org>
2799 * struct.cs (MyStructInfo.ctor): Make this work with empty
2800 structs; it's not allowed to use foreach() on null.
2802 2002-08-23 Martin Baulig <martin@gnome.org>
2804 * codegen.cs (CodeGen.InitMonoSymbolWriter): Tell the symbol
2805 writer the full pathname of the generated assembly.
2807 2002-08-23 Martin Baulig <martin@gnome.org>
2809 * statements.cs (FlowBranching.UsageVector.MergeChildren):
2810 A `finally' block never returns or breaks; improved handling of
2813 2002-08-23 Martin Baulig <martin@gnome.org>
2815 * statement.cs (Throw.Resolve): Allow `throw null'.
2817 2002-08-23 Martin Baulig <martin@gnome.org>
2819 * expression.cs (MemberAccess.ResolveMemberAccess): If this is an
2820 EventExpr, don't do a DeclaredOnly MemberLookup, but check whether
2821 `ee.EventInfo.DeclaringType == ec.ContainerType'. The
2822 MemberLookup would return a wrong event if this is an explicit
2823 interface implementation and the class has an event with the same
2826 2002-08-23 Martin Baulig <martin@gnome.org>
2828 * statement.cs (Block.AddChildVariableNames): New public method.
2829 (Block.AddChildVariableName): Likewise.
2830 (Block.IsVariableNameUsedInChildBlock): Likewise.
2831 (Block.AddVariable): Check whether a variable name has already
2832 been used in a child block.
2834 * cs-parser.jay (declare_local_variables): Mark all variable names
2835 from the current block as being used in a child block in the
2838 2002-08-23 Martin Baulig <martin@gnome.org>
2840 * codegen.cs (CodeGen.InitializeSymbolWriter): Abort if we can't
2841 find the symbol writer.
2843 * driver.cs: csc also allows the arguments to /define being
2844 separated by commas, not only by semicolons.
2846 2002-08-23 Martin Baulig <martin@gnome.org>
2848 * interface.cs (Interface.GetMembers): Added static check for events.
2850 2002-08-15 Martin Baulig <martin@gnome.org>
2852 * class.cs (MethodData.EmitDestructor): In the Expression.MemberLookup
2853 call, use ec.ContainerType.BaseType as queried_type and invocation_type.
2855 * ecore.cs (Expression.MemberLookup): Added documentation and explained
2856 why the MethodData.EmitDestructor() change was necessary.
2858 2002-08-20 Martin Baulig <martin@gnome.org>
2860 * class.cs (TypeContainer.FindMembers): Added static check for events.
2862 * decl.cs (MemberCache.AddMembers): Handle events like normal members.
2864 * typemanager.cs (TypeHandle.GetMembers): When queried for events only,
2865 use Type.GetEvents(), not Type.FindMembers().
2867 2002-08-20 Martin Baulig <martin@gnome.org>
2869 * decl.cs (MemberCache): Added a special method cache which will
2870 be used for method-only searched. This ensures that a method
2871 search will return a MethodInfo with the correct ReflectedType for
2874 2002-08-20 Martin Baulig <martin@gnome.org>
2876 * decl.cs (DeclSpace.FindMembers): Made this public.
2878 2002-08-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2880 * delegate.cs: fixed build on windows.
2881 [FIXME: Filed as bug #29150: MCS must report these errors.]
2883 2002-08-19 Ravi Pratap <ravi@ximian.com>
2885 * ecore.cs (StandardConversionExists): Return a false
2886 if we are trying to convert the void type to anything else
2887 since that is not allowed.
2889 * delegate.cs (DelegateInvocation.DoResolve): Ensure that
2890 we flag error 70 in the event an event is trying to be accessed
2891 directly from outside the declaring type.
2893 2002-08-20 Martin Baulig <martin@gnome.org>
2895 * typemanager.cs, decl.cs: Moved MemberList, IMemberContainer and
2896 MemberCache from typemanager.cs to decl.cs.
2898 2002-08-19 Martin Baulig <martin@gnome.org>
2900 * class.cs (TypeContainer): Implement IMemberContainer.
2901 (TypeContainer.DefineMembers): Create the MemberCache.
2902 (TypeContainer.FindMembers): Do better BindingFlags checking; only
2903 return public members if BindingFlags.Public was given, check
2904 whether members are static.
2906 2002-08-16 Martin Baulig <martin@gnome.org>
2908 * decl.cs (DeclSpace.Define): Splitted this in Define and
2909 DefineMembers. DefineMembers is called first and initializes the
2912 * rootcontext.cs (RootContext.DefineMembers): New function. Calls
2913 DefineMembers() on all our DeclSpaces.
2915 * class.cs (TypeContainer.Define): Moved all code to DefineMembers(),
2916 but call DefineMembers() on all nested interfaces. We call their
2917 Define() in our new Define() function.
2919 * interface.cs (Interface): Implement IMemberContainer.
2920 (Interface.Define): Moved all code except the attribute stuf to
2922 (Interface.DefineMembers): Initialize the member cache.
2924 * typemanager.cs (IMemberFinder): Removed this interface, we don't
2925 need this anymore since we can use MemberCache.FindMembers directly.
2927 2002-08-19 Martin Baulig <martin@gnome.org>
2929 * typemanager.cs (MemberCache): When creating the cache for an
2930 interface type, add all inherited members.
2931 (TypeManager.MemberLookup_FindMembers): Changed `ref bool searching'
2932 to `out bool used_cache' and documented it.
2933 (TypeManager.MemberLookup): If we already used the cache in the first
2934 iteration, we don't need to do the interfaces check.
2936 2002-08-19 Martin Baulig <martin@gnome.org>
2938 * decl.cs (DeclSpace.FindMembers): New abstract method. Moved this
2939 here from IMemberFinder and don't implement this interface anymore.
2940 (DeclSpace.MemberCache): Moved here from IMemberFinder.
2942 * typemanager.cs (IMemberFinder): This interface is now only used by
2943 classes which actually support the member cache.
2944 (TypeManager.builder_to_member_finder): Renamed to builder_to_declspace
2945 since we only put DeclSpaces into this Hashtable.
2946 (MemberLookup_FindMembers): Use `builder_to_declspace' if the type is
2947 a dynamic type and TypeHandle.GetTypeHandle() otherwise.
2949 2002-08-16 Martin Baulig <martin@gnome.org>
2951 * typemanager.cs (ICachingMemberFinder): Removed.
2952 (IMemberFinder.MemberCache): New property.
2953 (TypeManager.FindMembers): Merged this with RealFindMembers().
2954 This function will never be called from TypeManager.MemberLookup()
2955 so we can't use the cache here, just the IMemberFinder.
2956 (TypeManager.MemberLookup_FindMembers): Check whether the
2957 IMemberFinder has a MemberCache and call the cache's FindMembers
2959 (MemberCache): Rewrote larger parts of this yet another time and
2960 cleaned it up a bit.
2962 2002-08-15 Miguel de Icaza <miguel@ximian.com>
2964 * driver.cs (LoadArgs): Support quoting.
2966 (Usage): Show the CSC-like command line arguments.
2968 Improved a few error messages.
2970 2002-08-15 Martin Baulig <martin@gnome.org>
2972 * typemanager.cs (IMemberContainer.Type): New property.
2973 (IMemberContainer.IsInterface): New property.
2975 The following changes are conditional to BROKEN_RUNTIME, which is
2976 defined at the top of the file.
2978 * typemanager.cs (MemberCache.MemberCache): Don't add the base
2979 class'es members, but add all members from TypeHandle.ObjectType
2980 if we're an interface.
2981 (MemberCache.AddMembers): Set the Declared flag if member.DeclaringType
2982 is the current type.
2983 (MemberCache.CacheEntry.Container): Removed this field.
2984 (TypeHandle.GetMembers): Include inherited members.
2986 2002-08-14 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2988 * typemanager.cs: fixed compilation and added a comment on a field that
2991 2002-08-15 Martin Baulig <martin@gnome.org>
2993 * class.cs (ConstructorInitializer.Resolve): In the
2994 Expression.MemberLookup call, use the queried_type as
2997 * typemanager.cs (IMemberContainer.GetMembers): Removed the `bool
2998 declared' attribute, it's always true.
2999 (IMemberContainer.Parent, IMemberContainer.Name): New properties.
3000 (TypeManager.MemberLookup_FindMembers): [FIXME FIXME FIXME] Added
3001 temporary wrapper for FindMembers which tells MemberLookup whether
3002 members from the base classes are included in the return value.
3003 This will go away soon.
3004 (TypeManager.MemberLookup): Use this temporary hack here; once the
3005 new MemberCache is completed, we don't need to do the DeclaredOnly
3006 looping here anymore since the MemberCache will take care of this.
3007 (TypeManager.IsSubclassOrNestedChildOf): Allow `type == parent'.
3008 (MemberCache): When creating the MemberCache for a class, get
3009 members from the current class and all its base classes.
3010 (MemberCache.CacheEntry.Container): New field. This is a
3011 temporary hack until the Mono runtime is fixed to distinguish
3012 between ReflectedType and DeclaringType. It allows us to use MCS
3013 with both the MS runtime and the unfixed Mono runtime without
3014 problems and without accecting performance.
3015 (MemberCache.SearchMembers): The DeclaredOnly looping from
3016 TypeManager.MemberLookup is now done here.
3018 2002-08-14 Martin Baulig <martin@gnome.org>
3020 * statement.cs (MyStructInfo.MyStructInfo): Don't call
3021 Type.GetFields on dynamic types but get the fields from the
3022 corresponding TypeContainer.
3023 (MyStructInfo.GetStructInfo): Added check for enum types.
3025 * typemanager.cs (MemberList.IsSynchronized): Implemented.
3026 (MemberList.SyncRoot): Implemented.
3027 (TypeManager.FilterWithClosure): No need to check permissions if
3028 closure_start_type == closure_invocation_type, don't crash if
3029 closure_invocation_type is null.
3031 2002-08-13 Martin Baulig <martin@gnome.org>
3033 Rewrote TypeContainer.FindMembers to use a member cache. This
3034 gives us a speed increase of about 35% for the self-hosting MCS
3035 build and of about 15-20% for the class libs (both on GNU/Linux).
3037 * report.cs (Timer): New class to get enhanced profiling. This
3038 whole class is "TIMER" conditional since it remarkably slows down
3041 * class.cs (MemberList): New class. This is an IList wrapper
3042 which we're now using instead of passing MemberInfo[]'s around to
3043 avoid copying this array unnecessarily.
3044 (IMemberFinder.FindMember): Return a MemberList, not a MemberInfo [].
3045 (ICachingMemberFinder, IMemberContainer): New interface.
3046 (TypeManager.FilterWithClosure): If `criteria' is null, the name
3047 has already been checked, otherwise use it for the name comparision.
3048 (TypeManager.FindMembers): Renamed to RealMemberFinder and
3049 provided wrapper which tries to use ICachingMemberFinder.FindMembers
3050 if possible. Returns a MemberList, not a MemberInfo [].
3051 (TypeHandle): New class, implements IMemberContainer. We create
3052 one instance of this class per type, it contains a MemberCache
3053 which is used to do the member lookups.
3054 (MemberCache): New class. Each instance of this class contains
3055 all members of a type and a name-based hash table.
3056 (MemberCache.FindMembers): This is our new member lookup
3057 function. First, it looks up all members of the requested name in
3058 the hash table. Then, it walks this list and sorts out all
3059 applicable members and returns them.
3061 2002-08-13 Martin Baulig <martin@gnome.org>
3063 In addition to a nice code cleanup, this gives us a performance
3064 increase of about 1.4% on GNU/Linux - not much, but it's already
3065 half a second for the self-hosting MCS compilation.
3067 * typemanager.cs (IMemberFinder): New interface. It is used by
3068 TypeManager.FindMembers to call FindMembers on a TypeContainer,
3069 Enum, Delegate or Interface.
3070 (TypeManager.finder_to_member_finder): New PtrHashtable.
3071 (TypeManager.finder_to_container): Removed.
3072 (TypeManager.finder_to_delegate): Removed.
3073 (TypeManager.finder_to_interface): Removed.
3074 (TypeManager.finder_to_enum): Removed.
3076 * interface.cs (Interface): Implement IMemberFinder.
3078 * delegate.cs (Delegate): Implement IMemberFinder.
3080 * enum.cs (Enum): Implement IMemberFinder.
3082 * class.cs (TypeContainer): Implement IMemberFinder.
3084 2002-08-12 Martin Baulig <martin@gnome.org>
3086 * ecore.cs (TypeExpr.DoResolveType): Mark this as virtual.
3088 2002-08-12 Martin Baulig <martin@gnome.org>
3090 * ecore.cs (ITypeExpression): New interface for expressions which
3092 (TypeExpression): Renamed to TypeLookupExpression.
3093 (Expression.DoResolve): If we're doing a types-only lookup, the
3094 expression must implement the ITypeExpression interface and we
3095 call DoResolveType() on it.
3096 (SimpleName): Implement the new ITypeExpression interface.
3097 (SimpleName.SimpleNameResolve): Removed the ec.OnlyLookupTypes
3098 hack, the situation that we're only looking up types can't happen
3099 anymore when this method is called. Moved the type lookup code to
3100 DoResolveType() and call it.
3101 (SimpleName.DoResolveType): This ITypeExpression interface method
3102 is now doing the types-only lookup.
3103 (TypeExpr, TypeLookupExpression): Implement ITypeExpression.
3104 (ResolveFlags): Added MaskExprClass.
3106 * expression.cs (MemberAccess): Implement the ITypeExpression
3108 (MemberAccess.DoResolve): Added support for a types-only lookup
3109 when we're called via ITypeExpression.DoResolveType().
3110 (ComposedCast): Implement the ITypeExpression interface.
3112 * codegen.cs (EmitContext.OnlyLookupTypes): Removed. Call
3113 Expression.Resolve() with ResolveFlags.Type instead.
3115 2002-08-12 Martin Baulig <martin@gnome.org>
3117 * interface.cs (Interface.Define): Apply attributes.
3119 * attribute.cs (Attribute.ApplyAttributes): Added support for
3120 interface attributes.
3122 2002-08-11 Martin Baulig <martin@gnome.org>
3124 * statement.cs (Block.Emit): Only check the "this" variable if we
3125 do not always throw an exception.
3127 * ecore.cs (PropertyExpr.DoResolveLValue): Implemented, check
3128 whether the property has a set accessor.
3130 2002-08-11 Martin Baulig <martin@gnome.org>
3132 Added control flow analysis support for structs.
3134 * ecore.cs (ResolveFlags): Added `DisableFlowAnalysis' to resolve
3135 with control flow analysis turned off.
3136 (IVariable): New interface.
3137 (SimpleName.SimpleNameResolve): If MemberAccess.ResolveMemberAccess
3138 returns an IMemberExpr, call DoResolve/DoResolveLValue on it.
3139 (FieldExpr.DoResolve): Resolve the instance expression with flow
3140 analysis turned off and do the definite assignment check after the
3141 resolving when we know what the expression will resolve to.
3143 * expression.cs (LocalVariableReference, ParameterReference):
3144 Implement the new IVariable interface, only call the flow analysis
3145 code if ec.DoFlowAnalysis is true.
3146 (This): Added constructor which takes a Block argument. Implement
3147 the new IVariable interface.
3148 (MemberAccess.DoResolve, MemberAccess.DoResolveLValue): Call
3149 DoResolve/DoResolveLValue on the result of ResolveMemberLookup().
3150 This does the definite assignment checks for struct members.
3152 * class.cs (Constructor.Emit): If this is a non-static `struct'
3153 constructor which doesn't have any initializer, call
3154 Block.AddThisVariable() to tell the flow analysis code that all
3155 struct elements must be initialized before control returns from
3158 * statement.cs (MyStructInfo): New public class.
3159 (UsageVector.this [VariableInfo vi]): Added `int field_idx'
3160 argument to this indexer. If non-zero, check an individual struct
3161 member, not the whole struct.
3162 (FlowBranching.CheckOutParameters): Check struct members.
3163 (FlowBranching.IsVariableAssigned, SetVariableAssigned): Added
3164 overloaded versions of these methods which take an additional
3165 `int field_idx' argument to check struct members.
3166 (FlowBranching.IsParameterAssigned, SetParameterAssigned): Added
3167 overloaded versions of these methods which take an additional
3168 `string field_name' argument to check struct member.s
3169 (VariableInfo): Implement the IVariable interface.
3170 (VariableInfo.StructInfo): New public property. Returns the
3171 MyStructInfo instance of the variable if it's a struct or null.
3172 (Block.AddThisVariable): New public method. This is called from
3173 Constructor.Emit() for non-static `struct' constructor which do
3174 not have any initializer. It creates a special variable for the
3175 "this" instance variable which will be checked by the flow
3176 analysis code to ensure that all of the struct's fields are
3177 initialized before control returns from the constructor.
3178 (UsageVector): Added support for struct members. If a
3179 variable/parameter is a struct with N members, we reserve a slot
3180 in the usage vector for each member. A struct is considered fully
3181 initialized if either the struct itself (slot 0) or all its
3182 members are initialized.
3184 2002-08-08 Martin Baulig <martin@gnome.org>
3186 * driver.cs (Driver.MainDriver): Only report an error CS5001
3187 if there were no compilation errors.
3189 * codegen.cs (EmitContext.EmitContext): Use the DeclSpace's
3190 `UnsafeContext' property to determine whether the parent is in
3191 unsafe context rather than checking the parent's ModFlags:
3192 classes nested in an unsafe class are unsafe as well.
3194 2002-08-08 Martin Baulig <martin@gnome.org>
3196 * statement.cs (UsageVector.MergeChildren): Distinguish between
3197 `Breaks' and `Returns' everywhere, don't set `Breaks' anymore if
3198 we return. Added test17() and test18() to test-154.cs.
3200 2002-08-08 Martin Baulig <martin@gnome.org>
3202 * typemanager.cs (TypeManager.FilterWithClosure): If we have
3203 Family access, make sure the invoking type isn't a subclass of the
3204 queried type (that'd be a CS1540).
3206 * ecore.cs (Expression.MemberLookup): Added overloaded version of
3207 this method which takes an additional `Type invocation_type'.
3209 * expression.cs (BaseAccess.DoResolve): Use the base type as
3210 invocation and query type.
3211 (MemberAccess.DoResolve): If the lookup failed and we're about to
3212 report a CS0122, try a lookup with the ec.ContainerType - if this
3213 succeeds, we must report a CS1540.
3215 2002-08-08 Martin Baulig <martin@gnome.org>
3217 * ecore.cs (IMemberExpr): Added `bool IsInstance' property.
3218 (MethodGroupExpr): Implement the IMemberExpr interface.
3220 * expression (MemberAccess.ResolveMemberAccess): No need to have
3221 any special code for MethodGroupExprs anymore, they're now
3224 2002-08-08 Martin Baulig <martin@gnome.org>
3226 * typemanager.cs (TypeManager.FilterWithClosure): Check Assembly,
3227 Family, FamANDAssem and FamORAssem permissions.
3228 (TypeManager.IsSubclassOrNestedChildOf): New public method.
3230 2002-08-08 Martin Baulig <martin@gnome.org>
3232 * statement.cs (FlowBranchingType): Added LOOP_BLOCK.
3233 (UsageVector.MergeChildren): `break' breaks unless we're in a switch
3236 Thu Aug 8 10:28:07 CEST 2002 Paolo Molaro <lupus@ximian.com>
3238 * driver.cs: implemented /resource option to embed managed resources.
3240 2002-08-07 Martin Baulig <martin@gnome.org>
3242 * class.cs (FieldBase.Initializer): Renamed to `init' and made private.
3243 (FieldBase.HasFieldInitializer): New public property.
3244 (FieldBase.GetInitializerExpression): New public method. Resolves and
3245 returns the field initializer and makes sure it is only resolved once.
3246 (TypeContainer.EmitFieldInitializers): Call
3247 FieldBase.GetInitializerExpression to get the initializer, this ensures
3248 that it isn't resolved multiple times.
3250 * codegen.cs (EmitContext): Added `bool IsFieldInitialier'. This tells
3251 the resolving process (SimpleName/MemberLookup) that we're currently
3252 emitting a field initializer (which must not access any instance members,
3253 this is an error CS0236).
3255 * ecore.cs (SimpleName.Error_ObjectRefRequired): Added EmitContext
3256 argument, if the `IsFieldInitializer' flag is set, we must report and
3257 error CS0236 and not an error CS0120.
3259 2002-08-07 Martin Baulig <martin@gnome.org>
3261 * ecore.cs (IMemberExpr): New public interface.
3262 (FieldExpr, PropertyExpr, EventExpr): Implement IMemberExpr.
3263 (SimpleName.SimpleNameResolve): Call MemberAccess.ResolveMemberAccess
3264 if the expression is an IMemberExpr.
3266 * expression.cs (MemberAccess.ResolveMemberAccess): Allow `left'
3267 to be null, implicitly default to `this' if we're non-static in
3268 this case. Simplified the code a lot by using the new IMemberExpr
3269 interface. Also fixed bug #28176 here.
3271 2002-08-06 Martin Baulig <martin@gnome.org>
3273 * cs-parser.jay (SimpleLookup): Removed. We need to create
3274 ParameterReferences during semantic analysis so that we can do a
3275 type-only search when resolving Cast, TypeOf and SizeOf.
3276 (block): Pass the `current_local_parameters' to the Block's
3279 * class.cs (ConstructorInitializer): Added `Parameters parameters'
3280 argument to the constructor.
3281 (ConstructorInitializer.Resolve): Create a temporary implicit
3282 block with the parameters.
3284 * ecore.cs (SimpleName.SimpleNameResolve): Resolve parameter
3285 references here if we aren't doing a type-only search.
3287 * statement.cs (Block): Added constructor which takes a
3288 `Parameters parameters' argument.
3289 (Block.Parameters): New public property.
3291 * support.cs (InternalParameters.Parameters): Renamed `parameters'
3292 to `Parameters' and made it public readonly.

3296 * ecore.cs (Expression.Warning): Made this public as well.
3298 * report.cs (Report.Debug): Print the contents of collections.
3300 2002-08-06 Martin Baulig <martin@gnome.org>
3302 * ecore.cs (Expression.ResolveFlags): New [Flags] enum. This is
3303 used to tell Resolve() which kinds of expressions it may return.
3304 (Expression.Resolve): Added overloaded version of this method which
3305 takes a `ResolveFlags flags' argument. This can be used to tell
3306 Resolve() which kinds of expressions it may return. Reports a
3308 (Expression.ResolveWithSimpleName): Removed, use Resolve() with
3309 ResolveFlags.SimpleName.
3310 (Expression.Error118): Added overloaded version of this method which
3311 takes a `ResolveFlags flags' argument. It uses the flags to determine
3312 which kinds of expressions are allowed.
3314 * expression.cs (Argument.ResolveMethodGroup): New public method.
3315 Resolves an argument, but allows a MethodGroup to be returned.
3316 This is used when invoking a delegate.
3318 * TODO: Updated a bit.
3320 2002-08-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3322 Fixed compilation with csc.
3324 * ecore.cs: Expression.Error made public. Is this correct? Should
3325 Warning be made public too?
3327 * expression.cs: use ea.Location instead of ea.loc.
3328 [FIXME: Filed as bug #28607: MCS must report these errors.]
3330 2002-08-06 Martin Baulig <martin@gnome.org>
3332 * ecore.cs (Expression.loc): Moved the location here instead of
3333 duplicating it in all derived classes.
3334 (Expression.Location): New public property.
3335 (Expression.Error, Expression.Warning): Made them non-static and
3336 removed the location argument.
3337 (Expression.Warning): Added overloaded version which takes an
3338 `int level' argument.
3339 (Expression.Error118): Make this non-static and removed the
3340 expression and location arguments.
3341 (TypeExpr): Added location argument to the constructor.
3343 * expression.cs (StaticCallExpr): Added location argument to
3345 (Indirection, PointerArithmetic): Likewise.
3346 (CheckedExpr, UnCheckedExpr): Likewise.
3347 (ArrayAccess, IndexerAccess, UserCast, ArrayPtr): Likewise.
3348 (StringPtr): Likewise.
3351 2002-08-05 Martin Baulig <martin@gnome.org>
3353 * expression.cs (BaseAccess.DoResolve): Actually report errors.
3355 * assign.cs (Assign.DoResolve): Check whether the source
3356 expression is a value or variable.
3358 * statement.cs (Try.Resolve): Set ec.InTry/InCatch/InFinally
3359 while resolving the corresponding blocks.
3361 * interface.cs (Interface.GetInterfaceTypeByName): Actually report
3362 an error, don't silently return null.
3364 * statement.cs (Block.AddVariable): Do the error reporting here
3365 and distinguish between CS0128 and CS0136.
3366 (Block.DoResolve): Report all unused labels (warning CS0164).
3367 (LabeledStatement): Pass the location to the constructor.
3368 (LabeledStatement.HasBeenReferenced): New property.
3369 (LabeledStatement.Resolve): Set it to true here.
3371 * statement.cs (Return.Emit): Return success even after reporting
3372 a type mismatch error (CS0126 or CS0127), this is what csc does and
3373 it avoids confusing the users with any consecutive errors.
3375 2002-08-05 Martin Baulig <martin@gnome.org>
3377 * enum.cs (Enum.LookupEnumValue): Catch circular definitions.
3379 * const.cs (Const.LookupConstantValue): Catch circular definitions.
3381 * expression.cs (MemberAccess.DoResolve): Silently return if an
3382 error has already been reported.

3390 vector if we actually have any "out" parameters.
3392 2002-08-05 Martin Baulig <martin@gnome.org>
3394 * expression.cs (Binary.ResolveOperator): When combining delegates,
3395 they must have the same type.
3397 2002-08-05 Martin Baulig <martin@gnome.org>
3399 * typemanager.cs (TypeManager.GetArgumentTypes): Don't call
3400 PropertyInfo.GetIndexParameters() on dynamic types, this doesn't
3401 work with the ms runtime and we also don't need it: if we're a
3402 PropertyBuilder and not in the `indexer_arguments' hash, then we
3403 are a property and not an indexer.
3405 * class.cs (TypeContainer.AsAccessible): Use Type.IsArray,
3406 Type.IsPointer and Type.IsByRef instead of Type.HasElementType
3407 since the latter one doesn't work with the ms runtime.
3409 2002-08-03 Martin Baulig <martin@gnome.org>
3411 Fixed bugs #27998 and #22735.
3413 * class.cs (Method.IsOperator): New public field.
3414 (Method.CheckBase): Report CS0111 if there's already a method
3415 with the same parameters in the current class. Report CS0508 when
3416 attempting to change the return type of an inherited method.
3417 (MethodData.Emit): Report CS0179 if a method doesn't have a body
3418 and it's not marked abstract or extern.
3419 (PropertyBase): New abstract base class for Property and Indexer.
3420 (PropertyBase.CheckBase): Moved here from Property and made it work
3422 (PropertyBase.Emit): Moved here from Property.Emit, Indexer.Emit is
3423 the same so we can reuse it there.
3424 (Property, Indexer): Derive from PropertyBase.
3425 (MethodSignature.inheritable_property_signature_filter): New delegate
3426 to find properties and indexers.
3428 * decl.cs (MemberCore.CheckMethodAgainstBase): Added `string name'
3429 argument and improved error reporting.
3431 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): Renamed to
3432 EmptyReadOnlyParameters and made it a property.
3434 * typemanager.cs (TypeManager.GetArgumentTypes): Added overloaded
3435 version of this method which takes a `PropertyInfo indexer'.
3436 (TypeManager.RegisterIndexer): New method.

3456 internal for top-level types and private for nested types.
3457 (Delegate.Define): Report errors if the accessibility checks fail.
3459 * enum.cs (Enum.Enum): The default visibility is internal for
3460 top-level types and private for nested types.
3461 (Enum.DefineType): Compute the correct visibility.
3463 * modifiers.cs (Modifiers.TypeAttr): Added a version of this
3464 function which takes a `bool is_toplevel' instead of a TypeContainer.
3466 * typemanager.cs (TypeManager.IsBuiltinType): `void' is also a
3469 2002-08-02 Martin Baulig <martin@gnome.org>
3471 * expression.cs (LocalVariableReferenc): Added constructor which
3472 takes additional `VariableInfo vi' and `bool is_readonly' arguments.
3473 (LocalVariableReference.IsReadOnly): New property.
3474 (LocalVariableReference.DoResolveLValue): Report a CS1604 if the
3475 variable is readonly, use our own readonly flag to do this; you can
3476 use the new constructor to get a writable reference to a read-only
3479 * cs-parser.jay (foreach_statement, using_statement): Get a writable
3480 reference to the local variable.
3482 2002-08-01 Miguel de Icaza <miguel@ximian.com>

3572 local variables in this block (including the locals from all parent
3574 (Block.EmitMeta): Number all the variables.

3616 is a flag which specifies that it's either ref or out.
3617 (Parameter.GetParameterInfo (DeclSpace, int, out bool)): Changed
3618 the out parameter to `out Parameter.Modifier mod', also set the
3619 Parameter.Modifier.ISBYREF flag on it if it's either ref or out.

3668 (switch_section): The new block is a child of the current_block.
3669 Fixes bug #24007, added test-152.cs.
3671 2002-07-27 Martin Baulig <martin@gnome.org>
3673 * expression.cs (Invocation.EmitArguments): When calling a varargs
3674 function with only its fixed arguments, we need to pass an empty
3677 2002-07-27 Martin Baulig <martin@gnome.org>
3679 Mono 0.13 has been released.
3681 2002-07-25 Miguel de Icaza <miguel@ximian.com>
3683 * driver.cs: Rename --resource to --linkres, because that is what
3684 we do currently, we dont support --resource yet.
3686 * cs-tokenizer.cs: Fix test for reporting endif mismatches.
3688 2002-07-25 Martin Baulig <martin@gnome.org>
3690 * class.cs (MethodData): New public class. This is a `method builder'
3691 class for a method or one accessor of a Property/Indexer/Event.
3692 (MethodData.GetMethodFlags): Moved here from MemberBase.
3693 (MethodData.ApplyAttributes): Likewise.
3694 (MethodData.ApplyObsoleteAttribute): Likewise.
3695 (MethodData.ApplyConditionalAttribute): Likewise.
3696 (MethodData.ApplyDllImportAttribute): Likewise.
3697 (MethodData.CheckAbstractAndExternal): Likewise.
3698 (MethodData.Define): Formerly knows as MemberBase.DefineMethod().
3699 (MethodData.Emit): Formerly known as Method.Emit().
3700 (MemberBase): Moved everything which was specific to a single
3701 accessor/method to MethodData.
3702 (Method): Create a new MethodData and call Define() and Emit() on it.
3703 (Property, Indexer, Event): Create a new MethodData objects for each
3704 accessor and call Define() and Emit() on them.
3706 2002-07-25 Martin Baulig <martin@gnome.org>
3708 Made MethodCore derive from MemberBase to reuse the code from there.
3709 MemberBase now also checks for attributes.
3711 * class.cs (MethodCore): Derive from MemberBase, not MemberCore.
3712 (MemberBase.GetMethodFlags): Moved here from class Method and marked
3714 (MemberBase.DefineAccessor): Renamed to DefineMethod(), added
3715 `CallingConventions cc' and `Attributes opt_attrs' arguments.
3716 (MemberBase.ApplyAttributes): New virtual method; applies the
3717 attributes to a method or accessor.
3718 (MemberBase.ApplyObsoleteAttribute): New protected virtual method.
3719 (MemberBase.ApplyConditionalAttribute): Likewise.
3720 (MemberBase.ApplyDllImportAttribute): Likewise.
3721 (MemberBase.CheckAbstractAndExternal): Likewise.
3722 (MethodCore.ParameterTypes): This is now a property instead of a
3723 method, it's initialized from DoDefineParameters().
3724 (MethodCore.ParameterInfo): Removed the set accessor.
3725 (MethodCore.DoDefineParameters): New protected virtual method to
3726 initialize ParameterTypes and ParameterInfo.
3727 (Method.GetReturnType): We can now simply return the MemberType.
3728 (Method.GetMethodFlags): Override the MemberBase version and add
3729 the conditional flags.
3730 (Method.CheckBase): Moved some code from Define() here, call
3731 DoDefineParameters() here.
3732 (Method.Define): Use DoDefine() and DefineMethod() from MemberBase
3733 here to avoid some larger code duplication.
3734 (Property.Emit, Indexer.Emit): Call CheckAbstractAndExternal() to
3735 ensure that abstract and external accessors don't declare a body.
3737 * attribute.cs (Attribute.GetValidPieces): Make this actually work:
3738 `System.Attribute.GetCustomAttributes (attr.Type)' does a recursive
3739 lookup in the attribute's parent classes, so we need to abort as soon
3740 as we found the first match.
3741 (Attribute.Obsolete_GetObsoleteMessage): Return the empty string if
3742 the attribute has no arguments.
3744 * typemanager.cs (TypeManager.AddMethod): Now takes a MemberBase instead
3747 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3749 * cs-parser.jay: reverted previous patch.
3751 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3753 * cs-parser.jay: fixed bug #22119.
3755 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3757 * attribute.cs: fixed compilation. The error was:
3758 "attribute.cs(571,17): error CS0177: The out parameter 'is_error' must
3759 be assigned to before control leaves the current method."
3760 [FIXME: Filed as bug #28186: MCS must report this error.]
3762 2002-07-25 Martin Baulig <martin@gnome.org>
3764 * attribute.cs (Attribute.Conditional_GetConditionName): New static
3765 method to pull the condition name ouf of a Conditional attribute.
3766 (Attribute.Obsolete_GetObsoleteMessage): New static method to pull
3767 the obsolete message and error flag out of an Obsolete attribute.
3769 * class.cs (Method.GetMethodFlags): New public method to get the
3770 TypeManager.MethodFlags for this method.
3771 (Method.ApplyConditionalAttribute, Method.ApplyObsoleteAttribute): New
3773 (Method.Define): Get and apply the Obsolete and Conditional attributes;
3774 if we're overriding a virtual function, set the new private variable
3775 `parent_method'; call the new TypeManager.AddMethod().
3777 * typemanager.cs (TypeManager.AddMethod): New static method. Stores
3778 the MethodBuilder and the Method in a PtrHashtable.
3779 (TypeManager.builder_to_method): Added for this purpose.
3780 (TypeManager.MethodFlags): Added IsObsoleteError.
3781 (TypeManager.GetMethodFlags): Added `Location loc' argument. Lookup
3782 Obsolete and Conditional arguments in MethodBuilders. If we discover
3783 an Obsolete attribute, emit an appropriate warning 618 / error 619 with
3784 the message from the attribute.
3786 2002-07-24 Martin Baulig <martin@gnome.org>
3788 * cs-tokenizer.cs: Eat up trailing whitespaces and one-line comments in
3789 preprocessor directives, ensure that the argument to #define/#undef is
3790 exactly one identifier and that it's actually an identifier.
3792 Some weeks ago I did a `#define DEBUG 1' myself and wondered why this
3795 2002-07-24 Martin Baulig <martin@gnome.org>
3797 * statement.cs (Foreach.ForeachHelperMethods): Added `Type element_type',
3798 initialize it to TypeManager.object_type in the constructor.
3799 (Foreach.GetEnumeratorFilter): Set `hm.element_type' to the return type
3800 of the `hm.get_current' method if we're using the collection pattern.
3801 (Foreach.EmitCollectionForeach): Use `hm.element_type' as the source type
3802 for the explicit conversion to make it work when we're using the collection
3803 pattern and the `Current' property has a different return type than `object'.
3806 2002-07-24 Martin Baulig <martin@gnome.org>
3808 * delegate.cs (Delegate.VerifyMethod): Simply return null if the method
3809 does not match, but don't report any errors. This method is called in
3810 order for all methods in a MethodGroupExpr until a matching method is
3811 found, so we don't want to bail out if the first method doesn't match.
3812 (NewDelegate.DoResolve): If none of the methods in the MethodGroupExpr
3813 matches, report the 123. Fixes #28070.
3815 2002-07-24 Martin Baulig <martin@gnome.org>
3817 * expression.cs (ArrayAccess.EmitStoreOpcode): Moved the
3818 TypeManager.TypeToCoreType() to the top of the method so the
3819 following equality checks will work. Fixes #28107.
3821 2002-07-24 Martin Baulig <martin@gnome.org>
3823 * cfold.cs (ConstantFold.DoConstantNumericPromotions): "If either
3824 operand is of type uint, and the other operand is of type sbyte,
3825 short or int, the operands are converted to type long." -
3826 Actually do what this comment already told us. Fixes bug #28106,
3829 2002-07-24 Martin Baulig <martin@gnome.org>
3831 * class.cs (MethodBase): New abstract class. This is now a base
3832 class for Property, Indexer and Event to avoid some code duplication
3833 in their Define() and DefineMethods() methods.
3834 (MethodBase.DoDefine, MethodBase.DefineAccessor): Provide virtual
3835 generic methods for Define() and DefineMethods().
3836 (FieldBase): Derive from MemberBase, not MemberCore.
3837 (Property): Derive from MemberBase, not MemberCore.
3838 (Property.DefineMethod): Moved all the code from this method to the
3839 new MethodBase.DefineAccessor(), just call it with appropriate
3841 (Property.Define): Call the new Property.DoDefine(), this does some
3842 sanity checks and we don't need to duplicate the code everywhere.
3843 (Event): Derive from MemberBase, not MemberCore.
3844 (Event.Define): Use the new MethodBase.DefineAccessor() to define the
3845 accessors, this will also make them work with interface events.
3846 (Indexer): Derive from MemberBase, not MemberCore.
3847 (Indexer.DefineMethod): Removed, call MethodBase.DefineAccessor() insstead.
3848 (Indexer.Define): Use the new MethodBase functions.
3850 * interface.cs (InterfaceEvent.InterfaceEvent): Added `Location loc'
3851 argument to the constructor.
3852 (Interface.FindMembers): Added support for interface events.
3853 (Interface.PopluateEvent): Implemented.
3855 Added test-149.cs for this. This also fixes bugs #26067 and #24256.
3857 2002-07-22 Miguel de Icaza <miguel@ximian.com>
3859 * class.cs (TypeContainer.AddMethod): Adding methods do not use IsValid,
3860 but this is required to check for a method name being the same as
3861 the containing class.
3865 2002-07-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3867 * interface.cs: initialize variable.
3869 2002-07-23 Martin Baulig <martin@gnome.org>
3871 Implemented the IndexerName attribute in interfaces.
3873 * class.cs (TypeContainer.DefineIndexers): Don't set the indexer
3874 name if this is an explicit interface implementation.
3875 (Indexer.InterfaceIndexerName): New public variable. If we're
3876 implementing an interface indexer, this is the IndexerName in that
3877 interface. Otherwise, it's the IndexerName.
3878 (Indexer.DefineMethod): If we're implementing interface indexer,
3879 set InterfaceIndexerName. Use the new Pending.IsInterfaceIndexer
3880 and Pending.ImplementIndexer methods.
3881 (Indexer.Define): Also define the PropertyBuilder if we're
3882 implementing an interface indexer and this is neither an explicit
3883 interface implementation nor do the IndexerName match the one in
3886 * pending.cs (TypeAndMethods): Added `MethodInfo [] need_proxy'.
3887 If a method is defined here, then we always need to create a proxy
3888 for it. This is used when implementing interface indexers.
3889 (Pending.IsInterfaceIndexer): New public method.
3890 (Pending.ImplementIndexer): New public method.
3891 (Pending.InterfaceMethod): Added `MethodInfo need_proxy' argument.
3892 This is used when implementing interface indexers to define a proxy
3894 (Pending.VerifyPendingMethods): Look in the `need_proxy' array and
3895 define a proxy if necessary.
3897 * interface.cs (Interface.IndexerName): New public variable.
3898 (Interface.PopulateIndexer): Set the IndexerName.
3899 (Interface.DefineIndexers): New private method. Populate all the
3900 indexers and make sure their IndexerNames match.
3902 * typemanager.cs (IndexerPropertyName): Added support for interface
3905 2002-07-22 Martin Baulig <martin@gnome.org>
3907 * codegen.cs (EmitContext.HasReturnLabel): New public variable.
3908 (EmitContext.EmitTopBlock): Always mark the ReturnLabel and emit a
3909 ret if HasReturnLabel.
3910 (EmitContext.TryCatchLevel, LoopBeginTryCatchLevel): New public
3913 * statement.cs (Do.Emit, While.Emit, For.Emit, Foreach.Emit): Save
3914 and set the ec.LoopBeginTryCatchLevel.
3915 (Try.Emit): Increment the ec.TryCatchLevel while emitting the block.
3916 (Continue.Emit): If the ec.LoopBeginTryCatchLevel is smaller than
3917 the current ec.TryCatchLevel, the branch goes out of an exception
3918 block. In this case, we need to use Leave and not Br.
3920 2002-07-22 Martin Baulig <martin@gnome.org>
3922 * statement.cs (Try.Emit): Emit an explicit ret after the end of the
3923 block unless the block does not always return or it is contained in
3924 another try { ... } catch { ... } block. Fixes bug #26506.
3925 Added verify-1.cs to the test suite.
3927 2002-07-22 Martin Baulig <martin@gnome.org>
3929 * statement.cs (Switch.TableSwitchEmit): If we don't have a default,
3930 then we do not always return. Fixes bug #24985.
3932 2002-07-22 Martin Baulig <martin@gnome.org>
3934 * expression.cs (Invocation.OverloadedResolve): Do the BetterFunction()
3935 lookup on a per-class level; ie. walk up the class hierarchy until we
3936 found at least one applicable method, then choose the best among them.
3937 Fixes bug #24463 and test-29.cs.
3939 2002-07-22 Martin Baulig <martin@gnome.org>
3941 * typemanager.cs (TypeManager.ArrayContainsMethod): Don't check the
3942 return types of the methods. The return type is not part of the
3943 signature and we must not check it to make the `new' modifier work.
3944 Fixes bug #27999, also added test-147.cs.
3945 (TypeManager.TypeToCoreType): Added TypeManager.type_type.
3947 * expression.cs (Invocation.DoResolve): Call TypeManager.TypeToCoreType()
3948 on the method's return type.
3950 2002-07-21 Martin Baulig <martin@gnome.org>
3952 * assign.cs: Make this work if the rightmost source is a constant and
3953 we need to do an implicit type conversion. Also adding a few more tests
3954 to test-38.cs which should have caught this.
3956 * makefile.gnu: Disable debugging, there's already the mcs-mono2.exe
3957 target in the makefile for this. The makefile.gnu is primarily intended
3958 for end-users who don't want to debug the compiler.
3960 2002-07-21 Martin Baulig <martin@gnome.org>
3962 * assign.cs: Improved the Assign class so it can now handle embedded
3963 assignments (X = Y = Z = something). As a side-effect this'll now also
3964 consume less local variables. test-38.cs now passes with MCS, added
3965 a few new test cases to that test.
3967 2002-07-20 Martin Baulig <martin@gnome.org>
3969 * expression.cs (Binary.EmitBranchable): Emit correct unsigned branch
3970 instructions. Fixes bug #27977, also added test-146.cs.
3972 2002-07-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3974 * cs-tokenizer.cs: fixed getHex ().
3976 2002-07-19 Martin Baulig <martin@gnome.org>
3978 * expression.cs (Invocation.EmitParams): Use TypeManager.LookupType(),
3979 not Type.GetType() to lookup the array type. This is needed when
3980 we're constructing an array of a user-defined type.
3981 (ArrayAccess.EmitDynamicInitializers): Only emit the Ldelema for
3982 single-dimensional arrays, but also for single-dimensial arrays of
3985 2002-07-19 Martin Baulig <martin@gnome.org>
3987 * expression.cs (New.DoEmit): Create a new LocalTemporary each time
3988 this function is called, it's not allowed to share LocalBuilders
3991 2002-07-19 Martin Baulig <martin@gnome.org>
3993 * expression.cs (Argument.Resolve): Report an error 118 when trying
3994 to pass a type as argument.
3996 2002-07-18 Martin Baulig <martin@gnome.org>
3998 * ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
3999 Conv_R_Un for the signed `long' type.
4001 2002-07-15 Miguel de Icaza <miguel@ximian.com>
4003 * expression.cs (MemberAccess.DoResolve): Do not reuse the field
4004 `expr' for the temporary result, as that will fail if we do
4005 multiple resolves on the same expression.
4007 2002-07-05 Miguel de Icaza <miguel@ximian.com>
4009 * ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
4010 ec.TypeContainer for looking up aliases.
4012 * class.cs (TypeContainer): Remove LookupAlias from here.
4014 * decl.cs (DeclSpace); Move here.
4016 2002-07-01 Miguel de Icaza <miguel@ximian.com>
4018 * class.cs (FindMembers): Only call filter if the constructor
4019 bulider is not null.
4021 Also handle delegates in `NestedTypes' now. Now we will perform
4022 type lookups using the standard resolution process. This also
4025 * decl.cs (DeclSpace.ResolveType): New type resolution routine.
4026 This uses Expressions (the limited kind that can be parsed by the
4027 tree) instead of strings.
4029 * expression.cs (ComposedCast.ToString): Implement, used to flag
4030 errors since now we have to render expressions.
4032 (ArrayCreation): Kill FormElementType. Use ComposedCasts in
4035 * ecore.cs (SimpleName.ToString): ditto.
4037 * cs-parser.jay: Instead of using strings to assemble types, use
4038 Expressions to assemble the type (using SimpleName, ComposedCast,
4039 MemberAccess). This should fix the type lookups in declarations,
4040 because we were using a different code path for this.
4042 * statement.cs (Block.Resolve): Continue processing statements
4043 even when there is an error.
4045 2002-07-17 Miguel de Icaza <miguel@ximian.com>
4047 * class.cs (Event.Define): Also remove the `remove' method from
4048 the list of pending items.
4050 * expression.cs (ParameterReference): Use ldarg.N (0..3) to
4051 generate more compact code.
4053 2002-07-17 Martin Baulig <martin@gnome.org>
4055 * const.cs (Const.LookupConstantValue): Add support for constant
4056 `unchecked' and `checked' expressions.
4057 Also adding test case test-140.cs for this.
4059 2002-07-17 Martin Baulig <martin@gnome.org>
4061 * statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
4062 check whether mi.ReturnType implements the IEnumerator interface; the
4063 `==' and the IsAssignableFrom() will fail in this situation.
4065 2002-07-16 Ravi Pratap <ravi@ximian.com>
4067 * ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix
4070 2002-07-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
4072 * expression.cs: fixed bug #27811.
4074 2002-07-14 Miguel de Icaza <miguel@ximian.com>
4076 * expression.cs (ParameterReference.AddressOf): Patch from Paolo
4077 Molaro: when we are a ref, the value already contains a pointer
4078 value, do not take the address of it.
4080 2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
4081 * removed mb-parser.jay and mb-tokenizer.cs
4083 Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
4085 * expression.cs: check against the building corlib void type.
4087 Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
4089 * ecore.cs: fix for valuetype static readonly fields: when
4090 initializing them, we need their address, not the address of a copy.
4092 Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
4094 * typemanager.cs: register also enum_type in corlib.
4096 Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
4098 * class.cs: allow calling this (but not base) initializers in structs.
4100 Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
4102 * ecore.cs: make sure we compare against the building base types
4105 Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
4107 * typemanager.cs: fix TypeToCoreType() to handle void and object
4108 (corlib gets no more typerefs after this change).
4110 2002-07-12 Miguel de Icaza <miguel@ximian.com>
4112 * expression.cs (ArrayCreation.EmitArrayArguments): use
4113 Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
4115 (ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
4116 Conv_Ovf_I_Un for the array arguments. Even if C# allows longs as
4117 array indexes, the runtime actually forbids them.
4119 * ecore.cs (ExpressionToArrayArgument): Move the conversion code
4120 for array arguments here.
4122 * expression.cs (EmitLoadOpcode): System.Char is a U2, use that
4123 instead of the default for ValueTypes.
4125 (New.DoEmit): Use IsValueType instead of
4126 IsSubclassOf (value_type)
4127 (New.DoResolve): ditto.
4128 (Invocation.EmitCall): ditto.
4130 * assign.cs (Assign): ditto.
4132 * statement.cs (Unsafe): Ok, so I got the semantics wrong.
4133 Statements *are* currently doing part of their resolution during
4136 Expressions do always resolve during resolve, but statements are
4137 only required to propagate resolution to their children.
4139 2002-07-11 Miguel de Icaza <miguel@ximian.com>
4141 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
4143 (LoadAssembly): Do not add the dll if it is already specified
4145 (MainDriver): Add the System directory to the link path at the end,
4146 after all the other -L arguments.
4148 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
4149 wrong opcode for loading bytes and bools (ldelem.i1 instead of
4150 ldelem.u1) and using the opposite for sbytes.
4152 This fixes Digger, and we can finally run it.
4154 * driver.cs (UnixParseOption): Move the option parsing here.
4155 (CSCParseOption): Implement CSC-like parsing of options.
4157 We now support both modes of operation, the old Unix way, and the
4158 new CSC-like way. This should help those who wanted to make cross
4161 The only thing broken is that /r:, /reference: and /lib: are not
4162 implemented, because I want to make those have the same semantics
4163 as the CSC compiler has, and kill once and for all the confussion
4164 around this. Will be doing this tomorrow.
4166 * statement.cs (Unsafe.Resolve): The state is checked during
4167 resolve, not emit, so we have to set the flags for IsUnsfe here.
4169 2002-07-10 Miguel de Icaza <miguel@ximian.com>
4171 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
4172 not catch the Error_ObjectRefRequired in SimpleName (as it is
4173 possible to have a class/instance variable name that later gets
4174 deambiguated), we have to check this here.
4176 2002-07-10 Ravi Pratap <ravi@ximian.com>
4178 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
4179 make static and put into Expression.
4181 (Event.Define): Register the private field of the event with the
4182 TypeManager so that GetFieldFromEvent can get at it.
4184 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
4185 keep track of the private field associated with an event which
4188 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
4191 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
4193 2002-07-10 Miguel de Icaza <miguel@ximian.com>
4195 * expression.cs (Binary.EmitBranchable): this routine emits the
4196 Binary expression in a branchable context. This basically means:
4197 we need to branch somewhere, not just get the value on the stack.
4199 This works together with Statement.EmitBoolExpression.
4201 * statement.cs (Statement.EmitBoolExpression): Use
4204 2002-07-09 Miguel de Icaza <miguel@ximian.com>
4206 * statement.cs (For): Reduce the number of jumps in loops.
4208 (For): Implement loop inversion for the For statement.
4210 (Break): We can be breaking out of a Try/Catch controlled section
4211 (foreach might have an implicit try/catch clause), so we need to
4212 use Leave instead of Br.
4214 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
4215 now). If the instace expression supports IMemoryLocation, we use
4216 the AddressOf method from the IMemoryLocation to extract the
4217 address instead of emitting the instance.
4219 This showed up with `This', as we were emitting the instance
4220 always (Emit) instead of the Address of This. Particularly
4221 interesting when This is a value type, as we dont want the Emit
4222 effect (which was to load the object).
4224 2002-07-08 Miguel de Icaza <miguel@ximian.com>
4226 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
4228 * statement.cs (Checked): Set the CheckedState during the resolve
4229 process too, as the ConvCast operations track the checked state on
4230 the resolve process, and not emit.
4232 * cs-parser.jay (namespace_member_declaration): Flag that we have
4233 found a declaration when we do. This is used to flag error 1529
4235 * driver.cs: Report ok when we display the help only.
4237 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
4239 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
4241 2002-07-04 Miguel de Icaza <miguel@ximian.com>
4243 * cs-tokenizer.cs (define): We also have to track locally the
4244 defines. AllDefines is just used for the Conditional Attribute,
4245 but we also need the local defines for the current source code.
4247 2002-07-03 Miguel de Icaza <miguel@ximian.com>
4249 * statement.cs (While, For, Do): These loops can exit through a
4250 Break statement, use this information to tell whether the
4251 statement is the last piece of code.
4253 (Break): Flag that we break.
4255 * codegen.cs (EmitContexts): New `Breaks' state variable.
4257 2002-07-03 Martin Baulig <martin@gnome.org>
4259 * class.cs (TypeContainer.MethodModifiersValid): Allow override
4260 modifiers in method declarations in structs. Otherwise, you won't
4261 be able to override things like Object.Equals().
4263 2002-07-02 Miguel de Icaza <miguel@ximian.com>
4265 * class.cs (Method, Property, Indexer): Do not allow the public
4266 modifier to be used in explicit interface implementations.
4268 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
4269 override modifiers in method declarations in structs
4271 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
4273 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
4274 integer or real overflow, report an error
4276 2002-07-02 Martin Baulig <martin@gnome.org>
4278 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
4279 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
4280 to tell the runtime about our newly created System.Object and
4281 System.ValueType types.
4283 2002-07-02 Miguel de Icaza <miguel@ximian.com>
4285 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
4286 struct instead of Ldarg/Starg.
4288 2002-07-02 Martin Baulig <martin@gnome.org>
4290 * expression.cs (Indirection.Indirection): Call
4291 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
4293 2002-07-02 Martin Baulig <martin@gnome.org>
4295 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
4296 ValueType, call TypeManager.TypeToCoreType() on it.
4297 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
4298 the OpCodes.Newarr argument.
4300 2002-07-02 Martin Baulig <martin@gnome.org>
4302 * expression.cs (Invocation.EmitCall): When compiling corlib,
4303 replace all calls to the system's System.Array type to calls to
4304 the newly created one.
4306 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
4307 System.Array methods.
4308 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
4309 from the system's System.Array type which must be replaced.
4311 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
4313 * typemanager.cs: load unverifiable_code_ctor so we can build
4314 corlib using the correct type. Avoid using GetTypeCode() with
4316 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
4317 TypeManager.object_type to allow building corlib.
4319 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
4321 * ecore.cs: handle System.Enum separately in LoadFromPtr().
4323 2002-07-01 Martin Baulig <martin@gnome.org>
4325 * class.cs: Make the last change actually work, we need to check
4326 whether `ifaces != null' to avoid a crash.
4328 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
4330 * class.cs: when we build structs without fields that implement
4331 interfaces, we need to add the interfaces separately, since there is
4332 no API to both set the size and add the interfaces at type creation
4335 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
4337 * expression.cs: the dimension arguments to the array constructors
4338 need to be converted if they are a long.
4340 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
4342 * class.cs: don't emit ldarg.0 if there is no parent constructor
4343 (fixes showstopper for corlib).
4345 2002-06-29 Martin Baulig <martin@gnome.org>
4347 MCS now compiles corlib on GNU/Linux :-)
4349 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
4350 ie. check for MethodImplOptions.InternalCall.
4352 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
4353 and TypeManager.attribute_type are null, so we must explicitly check
4354 whether parent is not null to find out whether it's an attribute type.
4355 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
4356 and SetBuilder, not only if the property is neither abstract nor external.
4357 This is necessary to set the MethodImplOptions on the accessor methods.
4358 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
4359 SetBuilder, see Property.Emit().
4361 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
4362 populate "System.Object", "System.ValueType" and "System.Attribute" since
4363 they've already been populated from BootCorlib_PopulateCoreTypes().
4365 2002-06-29 Martin Baulig <martin@gnome.org>
4367 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
4368 is the NullLiteral, we also need to make sure that target_type is not
4371 2002-06-29 Martin Baulig <martin@gnome.org>
4373 * rootcontext.cs (RootContext.ResolveCore): We must initialize
4374 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
4375 before calling BootstrapCorlib_ResolveDelegate ().
4377 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
4379 * statement.cs: fixed build-breaker. All tests passed ok.
4381 2002-06-27 Martin Baulig <martin@gnome.org>
4383 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
4384 for System.Decimal when compiling corlib.
4386 2002-06-27 Martin Baulig <martin@gnome.org>
4388 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
4389 switch blocks which contain nothing but a default clause.
4391 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
4393 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
4395 2002-06-27 Martin Baulig <martin@gnome.org>
4397 * ecore.cs (PropertyExpr.PropertyExpr): Call
4398 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
4400 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
4401 is already a TypeBuilder.
4403 2002-06-27 Martin Baulig <martin@gnome.org>
4405 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
4406 `target_type == TypeManager.array_type', not IsAssignableFrom() in
4407 the "from an array-type to System.Array" case. This makes it work
4408 when compiling corlib.
4410 2002-06-27 Martin Baulig <martin@gnome.org>
4412 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
4413 non-static PropertyExpr, set its InstanceExpression. This makes
4414 the `ICollection.Count' property work in System/Array.cs.
4416 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
4418 * driver.cs: Made error handling more consistent. Errors now
4419 tracked by Report class, so many methods which used to return int
4420 now return void. Main() now prints success/failure and
4421 errors/warnings message.
4423 Renamed '--probe' compiler argument to '--expect-error'. Removed
4424 the magic number return values (123 and 124). Now, if the
4425 expected error occurs, the compiler exits with success (exit value
4426 0). If the compilation completes without seeing that particular
4427 error, the compiler exits with failure (exit value 1). The
4428 makefile in mcs/errors has been changed to handle the new behaviour.
4430 * report.cs: Made 'expected error' number a property and renamed
4431 it from 'Probe' to 'ExpectedError'.
4433 * genericparser.cs: Removed error handling support, since it is
4434 now all done by Report class.
4436 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
4437 class, so parse() no longer returns an int.
4439 * namespace.cs: Use Report.Error instead of GenericParser.error
4441 2002-06-22 Miguel de Icaza <miguel@ximian.com>
4443 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
4444 TypeContainer.AddOperator): At the front of the list put the
4445 explicit implementations, so they get resolved/defined first.
4447 2002-06-21 Miguel de Icaza <miguel@ximian.com>
4449 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
4450 interface type is implemented by this TypeContainer. Used during
4451 explicit interface implementation.
4453 (Property.Define, Indexer.Define, Method.Define): Validate that
4454 the given interface in the explicit implementation is one of the
4455 base classes for the containing type.
4457 Also if we are explicitly implementing an interface, but there is
4458 no match in the pending implementation table, report an error.
4460 (Property.Define): Only define the property if we are
4461 not explicitly implementing a property from an interface. Use the
4462 correct name also for those properties (the same CSC uses,
4463 although that is really not needed).
4465 (Property.Emit): Do not emit attributes for explicitly implemented
4466 properties, as there is no TypeBuilder.
4468 (Indexer.Emit): ditto.
4470 Hiding then means that we do not really *implement* a pending
4471 implementation, which makes code fail.
4473 2002-06-22 Martin Baulig <martin@gnome.org>
4475 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
4476 the return value of Object.GetType(). [FIXME: we need to do this whenever
4477 we get a type back from the reflection library].
4479 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
4481 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
4483 2002-06-20 Miguel de Icaza <miguel@ximian.com>
4485 * attribute.cs: Return null if we can not look up the type.
4487 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
4488 the interface types found.
4490 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
4491 interface types found.
4493 * typemanager.cs (GetInterfaces): Make this routine returns alll
4494 the interfaces and work around the lame differences between
4495 System.Type and System.Reflection.Emit.TypeBuilder in the results
4496 result for GetInterfaces.
4498 (ExpandInterfaces): Given an array of interface types, expand and
4499 eliminate repeated ocurrences of an interface. This expands in
4500 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
4503 2002-06-21 Martin Baulig <martin@gnome.org>
4505 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
4508 2002-06-21 Martin Baulig <martin@gnome.org>
4510 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
4511 and called with one of the core types, return the corresponding typebuilder for
4514 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
4517 2002-06-21 Martin Baulig <martin@gnome.org>
4519 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
4520 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
4521 (Expression.ConvertReferenceExplicit): Likewise.
4523 * expression.cs (ElementAccess.DoResolve): Likewise.
4524 (ElementAccess.DoResolveLValue): Likewise.
4526 2002-06-10 Martin Baulig <martin@gnome.org>
4528 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
4529 add the "value" parameter to the parameter list.
4531 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
4534 2002-06-19 Miguel de Icaza <miguel@ximian.com>
4536 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
4537 the argument to an int, uint, long or ulong, per the spec. Also
4538 catch negative constants in array creation.
4540 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
4542 * class.cs: do not allow the same interface to appear twice in
4543 the definition list.
4545 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
4547 * ecore.cs: don't use ldlen with System.Array.
4549 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
4551 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
4553 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
4555 * modifiers.cs: produce correct field attributes for protected
4556 internal. Easy fix so miguel can work on ther harder stuff:-)
4558 2002-06-18 Miguel de Icaza <miguel@ximian.com>
4560 * pending.cs: New file. Move the code from class.cs here.
4561 Support clearning the pending flag for all methods (when not doing
4562 explicit interface implementation).
4564 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
4566 * rootcontext.cs: added a couple more types needed to bootstrap.
4568 2002-06-17 Miguel de Icaza <miguel@ximian.com>
4570 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
4571 constructor in the type, instead of any constructor in the type
4572 hierarchy. Thanks to Paolo for finding this bug (it showed up as
4573 a bug in the Mono runtime when applying the params attribute).
4575 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
4576 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
4578 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
4580 * expression.cs (Unary.ResolveOperator): Use TypeManager
4581 to resolve the type.
4583 2002-06-13 Ravi Pratap <ravi@ximian.com>
4585 * cs-parser.jay (enum_member_declaration): Pass in the attributes
4588 * enum.cs (AddEnumMember): Add support to store the attributes associated
4589 with each member too.
4591 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
4592 field builders too - this takes care of the enum member case.
4594 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
4596 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
4597 address-of operator on both value types and pointers.
4599 2002-06-10 Martin Baulig <martin@gnome.org>
4601 * interface.cs (Interface.PopulateIndexer): Add the indexer's
4602 PropertyBuilder to the `property_builders' list.
4604 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
4605 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
4606 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
4607 find any indexers which are inherited from an interface.
4609 2002-06-09 Martin Baulig <martin@gnome.org>
4611 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
4612 the same type as the constant if necessary. There's also a test-130.cs
4615 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
4617 * typemanager.cs (TypeManager.ChangeType): Previously known as
4618 Enum.ChangeEnumType().
4620 2002-06-09 Martin Baulig <martin@gnome.org>
4622 * expression.cs (Cast.TryReduce): Added support for consts.
4624 2002-06-08 Ravi Pratap <ravi@ximian.com>
4626 * class.cs (Accessor): Hold attributes information so we can pass
4629 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
4630 Modify to pass in attributes attached to the methods.
4632 (add_accessor_declaration, remove_accessor_declaration): Ditto.
4634 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
4635 to handle the Accessor kind :-)
4637 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
4639 2002-06-08 Martin Baulig <martin@gnome.org>
4641 * expression.cs (Unary.TryReduceNegative): Added support for
4644 2002-06-08 Martin Baulig <martin@gnome.org>
4646 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
4647 name can't be found in the `defined_names' - the caller will do a
4648 MemberLookup in this case and thus find methods in System.Enum
4649 such as Enum.IsDefined().
4651 2002-06-08 Martin Baulig <martin@gnome.org>
4653 * enum.cs (Enum.ChangeEnumType): This is a custom version of
4654 Convert.ChangeType() which works with TypeBuilder created types.
4655 (Enum.LookupEnumValue, Enum.Define): Use it here.
4657 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
4658 `TypeBuilder.BaseType != null' check.
4659 (TypeContainer.FindMembers): Only lookup parent members if we
4660 actually have a parent.
4661 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
4662 (ConstructorInitializer.Resolve): Likewise.
4664 * interface.cs (Interface.FindMembers): Added
4665 `TypeBuilder.BaseType != null' check.
4667 * rootcontext.cs (RootContext.ResolveCore): Added
4668 "System.Runtime.CompilerServices.IndexerNameAttribute" to
4669 classes_second_stage.
4671 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
4672 debug_type and trace_type when compiling with --nostdlib.
4674 2002-06-07 Martin Baulig <martin@gnome.org>
4676 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
4677 (AddField): Set it to true when adding a non-static field.
4678 (DefineType): Use `have_nonstatic_fields' to find out whether we
4679 have non-static fields, not `Fields != null'.
4681 2002-06-02 Miguel de Icaza <miguel@ximian.com>
4683 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
4684 dereferencing a null on the static-field code path)
4686 2002-05-30 Martin Baulig <martin@gnome.org>
4688 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
4689 to take command line arguments. Use reflection to call the new
4690 custom `Initialize' function on the symbol writer and pass it the
4691 command line arguments.
4693 * driver.cs (--debug-args): New command line argument to pass command
4694 line arguments to the symbol writer.
4696 2002-05-28 Miguel de Icaza <miguel@ximian.com>
4698 * assign.cs (DoResolve): Forgot to do the implicit conversion to
4699 the target type for indexers and properties. Thanks to Joe for
4702 2002-05-27 Miguel de Icaza <miguel@ximian.com>
4704 * typemanager.cs (MethodFlags): returns the method flags
4705 (Obsolete/ShouldIgnore) that control warning emission and whether
4706 the invocation should be made, or ignored.
4708 * expression.cs (Invocation.Emit): Remove previous hack, we should
4709 not do this on matching a base type, we should do this based on an attribute
4711 Only emit calls to System.Diagnostics.Debug and
4712 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
4713 on the command line.
4715 * rootcontext.cs: Global settings for tracing and debugging.
4717 * cs-tokenizer.cs (define): New utility function to track
4718 defines. Set the global settings for TRACE and DEBUG if found.
4720 2002-05-25 Ravi Pratap <ravi@ximian.com>
4722 * interface.cs (Populate*): Pass in the TypeContainer as well as
4723 the DeclSpace as parameters so that we can create EmitContexts and
4724 then use that to apply attributes etc.
4726 (PopulateMethod, PopulateEvent, PopulateProperty)
4727 (PopulateIndexer): Apply attributes everywhere.
4729 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
4732 (ApplyAttributes): Update accordingly.
4734 We now apply interface attributes for all members too.
4736 2002-05-26 Miguel de Icaza <miguel@ximian.com>
4738 * class.cs (Indexer.Define); Correctly check if we are explicit
4739 implementation (instead of checking the Name for a ".", we
4740 directly look up if the InterfaceType was specified).
4742 Delay the creation of the PropertyBuilder.
4744 Only create the PropertyBuilder if we are not an explicit
4745 interface implementation. This means that explicit interface
4746 implementation members do not participate in regular function
4747 lookups, and hence fixes another major ambiguity problem in
4748 overload resolution (that was the visible effect).
4750 (DefineMethod): Return whether we are doing an interface
4753 * typemanager.cs: Temporary hack until we get attributes in
4754 interfaces (Ravi is working on that) and we get IndexerName
4755 support in interfaces.
4757 * interface.cs: Register the indexers as properties.
4759 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
4760 warning, I have verified that this is a bug in the .NET runtime
4761 (JavaScript suffers of the same problem).
4763 * typemanager.cs (MemberLookup): When looking up members for
4764 interfaces, the parent of an interface is the implicit
4765 System.Object (so we succeed in searches of Object methods in an
4766 interface method invocation. Example: IEnumerable x; x.ToString
4769 2002-05-25 Miguel de Icaza <miguel@ximian.com>
4771 * class.cs (Event): Events should also register if they do
4772 implement the methods that an interface requires.
4774 * typemanager.cs (MemberLookup); use the new GetInterfaces
4777 (GetInterfaces): The code used to lookup interfaces for a type is
4778 used in more than one place, factor it here.
4780 * driver.cs: Track the errors at the bottom of the file, we kept
4783 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
4784 instance if the method we are calling is static!
4786 2002-05-24 Miguel de Icaza <miguel@ximian.com>
4788 * attribute.cs (ApplyAttributes): Make this function filter out
4789 the IndexerName attribute (as that attribute in reality is never
4790 applied) and return the string constant for the IndexerName
4793 * class.cs (TypeContainer.Emit): Validate that all the indexers
4794 have the same IndexerName attribute, and if so, set the
4795 DefaultName attribute on the class.
4797 * typemanager.cs: The return value might contain other stuff (not
4798 only methods). For instance, consider a method with an "Item"
4799 property and an Item method.
4801 * class.cs: If there is a problem with the parameter types,
4804 2002-05-24 Ravi Pratap <ravi@ximian.com>
4806 * ecore.cs (ImplicitConversionExists): Wrapper function which also
4807 looks at user defined conversion after making a call to
4808 StandardConversionExists - we need this for overload resolution.
4810 * expression.cs : Update accordingly the various method calls.
4812 This fixes 2 bugs filed against implicit user defined conversions
4814 2002-05-22 Miguel de Icaza <miguel@ximian.com>
4816 * statement.cs: Track the result of the assignment.
4818 2002-05-21 Miguel de Icaza <miguel@ximian.com>
4820 * expression.cs (MemberAccess): Improved error reporting for
4821 inaccessible members.
4823 2002-05-22 Martin Baulig <martin@gnome.org>
4825 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
4826 itself with debugging support.
4828 2002-05-22 Martin Baulig <martin@gnome.org>
4830 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
4831 Removed, this isn't needed anymore.
4833 2002-05-20 Martin Baulig <martin@gnome.org>
4835 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
4836 be underlying type for an enum.
4838 2002-05-20 Miguel de Icaza <miguel@ximian.com>
4840 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
4841 that splits out the loading of just the core types.
4843 * rootcontext.cs (ResolveCore): Split the struct resolution in
4844 two, so we can load the enumeration underlying types before any
4847 * expression.cs (Is): Bandaid until we fix properly Switch (see
4848 bug #24985 for details).
4850 * typemanager.cs (ImplementsInterface): The hashtable will contain
4851 a null if there are no interfaces implemented.
4853 2002-05-18 Miguel de Icaza <miguel@ximian.com>
4855 * cs-parser.jay (indexer_declarator): It is fine to have array
4858 2002-05-17 Miguel de Icaza <miguel@ximian.com>
4860 * typemanager.cs: (RegisterBuilder): New function used to register
4861 TypeBuilders that implement interfaces. Since
4862 TypeBuilder.GetInterfaces (as usual) does not work with lame
4864 (AddUserType): register interfaces.
4866 (ImplementsInterface): Use the builder_to_ifaces hash if we are
4867 dealing with TypeBuilder. Also, arrays are showing up as
4868 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
4869 methods can not be invoked on them!
4871 * ecore.cs (ExplicitReferenceConversionExists): Made public.
4872 (ImplicitReferenceConversionExists): Split out from
4873 StandardConversionExists.
4875 * expression.cs (As): We were only implementing one of the three
4876 cases for the as operator. We now implement them all.
4877 (Is): Implement the various other cases for Is as well.
4879 * typemanager.cs (CACHE): New define used to control if we want or
4880 not the FindMembers cache. Seems to have a negative impact on
4881 performance currently
4883 (MemberLookup): Nested types have full acess to
4884 enclosing type members
4886 Remove code that coped with instance/static returns for events, we
4887 now catch this in RealFindMembers.
4889 (RealFindMembers): only perform static lookup if the instance
4890 lookup did not return a type or an event.
4892 2002-05-17 Miguel de Icaza <miguel@ximian.com>
4894 * assign.cs (CompoundAssign): We pass more semantic information
4895 now to Compound Assignments than we did before: now we have all
4896 the information at hand, and now we resolve the target *before* we
4897 do the expression expansion, which allows the "CacheValue" method
4898 to have the effect we intended (before, a [x] += 1 would generate
4899 two differen ArrayAccess expressions from the ElementAccess,
4900 during the resolution process).
4902 (CompoundAssign.DoResolve): Resolve target and original_source here.
4904 2002-05-16 Miguel de Icaza <miguel@ximian.com>
4906 * expression.cs (ArrayAccess): dropped debugging information.
4908 * typemanager.cs: Small bug fix: I was always returning i_members,
4909 instead of one of i_members or s_members (depending on which had
4912 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
4913 method is invoked before any code generation takes place, and it
4914 is a mechanism to inform that the expression will be invoked more
4915 than once, and that the method should use temporary values to
4916 avoid having side effects
4918 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
4920 * ecore.cs (Expression.CacheTemporaries): Provide empty default
4923 * expression.cs (Indirection, ArrayAccess): Add support for
4924 CacheTemporaries in these two bad boys.
4926 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
4928 (StoreFromPtr): Handle stobj as well.
4930 * expression.cs (UnaryMutator): Share more code.
4932 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
4933 down: I was not tracking the Filter function as well, which
4934 was affecting the results of the cache.
4936 2002-05-15 Miguel de Icaza <miguel@ximian.com>
4938 * attribute.cs: Remove the hack to handle the CharSet property on
4941 2002-05-14 Miguel de Icaza <miguel@ximian.com>
4943 * attribute.cs (DoResolve): More uglyness, we now only try to
4944 resolve the attribute partially, to extract the CharSet
4945 information (only if we are a StructLayout attribute). Otherwise
4947 (GetExtraTypeInfo): Add some code to conditionally kill in the
4948 future this. I am more and more convinced that the .NET
4949 framework has special code to handle the attribute setting on
4952 * expression.cs (IsParamsMethodApplicable): Revert my previous
4953 foreach change here, it was wrong.
4955 2002-05-13 Miguel de Icaza <miguel@ximian.com>
4957 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
4958 (pp_expr): do not abort on unknown input, just return.
4959 (eval): abort if there are pending chars.
4961 * attribute.cs (Attribute.Resolve): Positional parameters are
4962 optional. Deal with that case.
4964 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
4965 the Ansi/Unicode/Auto information for the type.
4967 (TypeContainer.DefineType): instantiate the EmitContext here, as
4968 we will be using it during the type definition (to resolve
4969 attributes) and during the emit phase.
4971 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
4972 to pull type information out of the attributes
4974 (Attribute.Resolve): track the constructor builder, and allow for
4975 multiple invocations (structs and classes will use this).
4977 * ecore.cs (MemberLookupFinal): new version with all the
4978 parameters customizable.
4980 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
4981 constructors. Return if the result value is null (as the error
4982 would have been flagged already by MemberLookupFinal)
4984 Do not allow instances of abstract classes or interfaces to be
4987 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
4988 We have to compare the assembly property here when dealing with
4989 FamANDAssem and Assembly access modifiers, because we might be
4990 creating an assembly from *modules* (that means that we are not
4991 getting TypeBuilders for types defined in other modules that are
4992 part of this assembly).
4994 (Method.Emit): If the method is marked abstract and has a body,
4997 (TypeContainer.DefineMembers): If both the defined member and the
4998 parent name match are methods, then do not emit any warnings: let
4999 the Method.Define routine take care of flagging warnings. But if
5000 there is a mismatch (method overrides something else, or method is
5001 overriwritten by something, then emit warning).
5003 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
5004 set to null, this means `do not check for the return type on the
5007 (Method.Define): set the return type for the method signature to
5008 null, so that we get methods with the same name and parameters and
5009 different return types. This is used to flag warning 114 (you are
5010 hiding a method, and you probably want to use the new/override
5013 * typemanager.cs (MemberLookup): Implemented proper access
5014 control, closing a long standing set of bug reports. The problem
5015 was that the Framework only has two bits: Public and NonPublic,
5016 and NonPublic includes private and protected methods, but we need
5017 to enforce the FamANDAssem, FamOrAssem and Family.
5019 2002-05-11 Miguel de Icaza <miguel@ximian.com>
5021 * statement.cs (GotoCase): Return true: Ammounts to giving up
5022 knowledge on whether we return or not, and letting the other case
5023 be responsible for it.
5025 2002-05-10 Miguel de Icaza <miguel@ximian.com>
5027 * driver.cs: Do not load directories for each file processed, only
5028 do it if there is a pattern.
5030 * ecore.cs: Report readonly assigns here as well, as we might have
5031 been resolved only by MemberAccess.
5033 (SimpleName.SimpleNameResolve): Also be useful for LValue
5034 resolution. We need this to propagate assign to local readonly variables
5036 * typemanager.cs: Use a ptrhashtable for the criteria, because we
5037 do not want to reuse potential criteria memory.
5039 * class.cs (MyEventBuilder): Set reflected_type;
5041 * ecore.cs (Constantify): Added support for constifying bools.
5043 (RootContext.LookupType): Added a cache for values looked up in
5044 the declaration space.
5046 * typemanager.cs (FindMembers): Now is a front-end to
5047 RealFindMembers, and provides a two-level hashtable-based cache to
5050 15% performance improvement: from 22.5 to 19.2 seconds.
5052 * expression.cs (IsParamsMethodApplicable): use foreach.
5053 (Invocation.DoResolve): ditto.
5054 (New.DoResolve): ditto.
5055 (ArrayCreation.DoResolve): ditto.
5057 * ecore.cs (FindMostEncompassingType): use foreach.
5059 * delegate.cs (NewDelegate.DoResolve): Use foreach
5061 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
5062 (RemoveMethods): use foreach.
5064 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
5065 nested foreach statements instead of for, and also break out of
5066 the inner loop once a match is found.
5068 (Invocation.OverloadResolve): Use foreach, simplify the code.
5070 2002-05-08 Miguel de Icaza <miguel@ximian.com>
5072 * cfold.cs (BinaryFold): During an enumeration evaluation context,
5073 we actually unwrap the expression to allow for extra information
5076 * expression.cs: Use Shr_Un on unsigned operations.
5078 2002-05-08 Ravi Pratap <ravi@ximian.com>
5080 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
5081 applicable operators was not being considered correctly. This closes
5082 the bug Miguel reported.
5084 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
5086 * attribute.cs: check that the type derives from System.Attribute
5087 and report the correct error in that case (moved the duplicate code to
5088 its own method, too).
5090 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
5092 * attribute.cs: lookup attribute type name as the spec says: first the
5093 bare attribute name and then name + "Attribute" (nant compiles with
5094 mcs after this fix).
5096 2002-05-07 Miguel de Icaza <miguel@ximian.com>
5098 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
5099 Because of the way we parse things, we should try to see if a
5100 UIntConstant can fit in an integer.
5102 2002-05-07 Ravi Pratap <ravi@ximian.com>
5104 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
5105 when we are in an explicit context.
5107 (ConvertReferenceExplicit): When converting from Iface type S to Class
5108 T make sure the rules are implemented as an OR.
5110 * parameter.cs (ParameterType): Make it a property for now although the
5111 purpose really isn't anything immediate.
5113 * expression.cs (Is*Applicable): Do better checking on the parameter type
5114 of a ref/out parameter. The ones from the system assemblies are already
5115 marked with the correct type so we don't need to do any correction.
5117 * ecore.cs (StandardConversionExists): Conversion from Interface types to
5118 the object type is standard too so include that.
5120 2002-05-06 Miguel de Icaza <miguel@ximian.com>
5122 * ecore.cs (StandardConversionExists): Augment with missing code:
5123 deal with IntConstant, LongConstants and Enumerations.
5125 * assign.cs: Report the error, instead of failing silently
5127 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
5128 typecontainer that they are declared, because the
5129 typecontainer/namespace will have the list of using clauses that
5132 Assembly Attributes were escaping the normal registration
5135 (EmitCode): Apply attributes within an EmitContext that represents
5136 the container they were declared on.
5138 * cs-parser.jay: Track bases for structs. How did I get this wrong?
5140 2002-05-06 Ravi Pratap <ravi@ximian.com>
5142 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
5143 Revamp completely - make much cleaner as we now operate only
5146 (FindMostSpecificSource, FindMostSpecificTarget): New methods
5147 to implement the logic detailed in the spec more correctly.
5149 (UserDefinedConversion): Update accordingly.
5151 2002-05-06 Miguel de Icaza <miguel@ximian.com>
5153 * statement.cs: Return flow analysis information up.
5155 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
5158 (token): Do not consume an extra character before calling
5161 2002-05-06 Piers Haken <piersh@friskit.com>
5163 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
5165 2002-05-06 Miguel de Icaza <miguel@ximian.com>
5167 * class.cs (Constructor.Emit): Set the IsStatic flag in the
5168 EmitContext during the instance constructor initializer
5169 resolution, to stop access to instance variables.
5171 This is mandated by the spec, last paragraph of the `constructor
5172 initializers' section.
5174 2002-05-05 Miguel de Icaza <miguel@ximian.com>
5176 * cs-parser.jay, class.cs (Accessor): new class used to represent
5177 an accessor (get or set). In the past we used `null' to represent
5178 a missing accessor. But this is ambiguous because there was no
5179 way to tell in abstract indexers/properties if one of them was
5182 Now there is a way of addressing that.
5184 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
5185 instead of FindMembers.
5187 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
5188 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
5190 * attribute.cs: Treat indexers and properties as the same in terms
5191 of applying attributes
5193 * ecore.cs (FindMostEncompassedType): Use statically initialized
5194 EmptyExpressions()s like we do elsewhere to avoid creating useless
5195 objects (and we take this out of the tight loop).
5197 (GetConversionOperators): Move the code to extract the actual
5198 operators to a separate routine to clean things up.
5200 2002-05-04 Miguel de Icaza <miguel@ximian.com>
5202 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
5203 events are always registered FieldBuilders.
5205 * class.cs (FieldBase): New class shared by Fields
5207 * delegate.cs: If we are a toplevel delegate, use our full name.
5208 If we are a nested delegate, then only use our tail name.
5210 2002-05-02 Ravi Pratap <ravi@ximian.com>
5212 * expression.cs (IsApplicable): Ensure that we add the "&" to
5213 ref/out types before comparing it with the type of the argument.
5215 (IsParamsMethodApplicable): Ditto.
5217 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
5220 * delegate.cs : Handle the case when we have more than one applicable
5221 method. Flag an error only when we finish checking all.
5223 2002-05-02 Miguel de Icaza <miguel@ximian.com>
5225 * expression.cs: Add support for boolean static initializers.
5227 2002-05-01 Miguel de Icaza <miguel@ximian.com>
5229 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
5231 * parameter.cs (ComputeParameterTypes,
5232 ComputeAndDefineParameterTypes): Better error handling: now we
5233 clear the `types' cache if we fail during any of the type lookups.
5234 We also return the status code correctly to our caller
5236 * delegate.cs: If we fail to define a delegate, abort the extra
5239 * expression.cs (Binary.ResolveOperator): for
5240 operator==(object,object) and operator !=(object, object) we also
5241 have to verify that there is an implicit conversion from one to
5244 (ArrayAccess.DoResolve): Array Access can operate on
5247 2002-04-30 Miguel de Icaza <miguel@ximian.com>
5249 * assign.cs (CompoundAssign): A new class used as a "flag" that
5250 the assignment actually is happening as part of a compound
5251 assignment operator.
5253 During compound assignment, a few new rules exist to enable things
5260 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
5261 to the type of x) if y is implicitly convertible to the type of x,
5262 and the operator is a builtin operator and the return type of the
5263 operator is explicitly convertible to the type of x.
5265 * rootcontext.cs: Reset warning level to 2. 4 catches various
5266 "interesting" features in mcs, we must clean this up at some
5267 point, but currently am trying to kill other bugs ;-)
5269 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
5270 in container classes as well.
5272 * expression.cs (Binary.ResolveOperator): Handle string case
5273 before anything else (as operator overloading does emit an error
5274 before doing anything else).
5276 This code could go away when we move to a table driven model, but
5277 i could not come up with a good plan last night.
5279 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
5281 * typemanager.cs (CSharpName): reimplementation using regex.
5282 * class.cs: added null check for fields in Emit
5283 * rootcontext.cs: set warninglevel to 4
5285 2002-04-29 Miguel de Icaza <miguel@ximian.com>
5287 * typemanager.cs (CSharpName): reimplemented with Lupus
5290 2002-04-28 Miguel de Icaza <miguel@ximian.com>
5292 * statement.cs (If): correclty implement Resolve, because we were
5293 not catching sem errors in there. The same process is needed
5295 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
5298 (Statement.Warning_DeadCodeFound): Factorize code.
5299 (While): Report dead code here too.
5301 (Statement): Added Resolve virtual method to allow
5302 for resolution split from the emit code.
5304 2002-04-26 Miguel de Icaza <miguel@ximian.com>
5306 * statement.cs (EmitBoolExpression): No longer try to resolve the
5308 (MakeBoolean): New utility function that resolve, implicitly
5309 converts to boolean and tags the expression.
5312 (If, Do): Implement dead code elimination.
5313 (While): Implement loop inversion
5315 (Do, While, For, If): Resolve the expression prior to calling our
5318 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
5321 - added method Report28 (warning: program has more than one entry point)
5322 - added method IsEntryPoint, implements paragraph 10.1 of the spec
5323 - modified method Method.Define, the part at the end of the method
5325 * rootcontext.cs: added static public Location EntryPointLocation;
5327 * ../errors/cs0028.cs : Add test case for the above warning.
5330 - modified method CSharpName to allow arrays of primitive type to
5331 be printed nicely (e.g. instead of System.Int32[][] it now prints
5333 - added method CSharpSignature: returns the signature of a method
5334 in string format to be used in reporting errors, warnings, etc.
5336 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
5339 2002-04-26 Ravi Pratap <ravi@ximian.com>
5341 * delegate.cs (Define): Fix extremely silly bug where I was
5342 setting the type of the 'object' parameter of the BeginInvoke
5343 method to System.IAsyncResult instead of System.Object ;-)
5345 2002-04-26 Miguel de Icaza <miguel@ximian.com>
5347 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
5350 (Constructor.Emit): return if we fail to initialize the
5351 constructor. Another door closed!
5353 * expression.cs (New.DoResolve): Improve error message (from -6 to
5354 1501). Use DeclaredOnly lookup to find the exact constructor.
5356 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
5357 loop. This is useful.
5359 * cs-parser.jay: Adjust the default parameters so that destructors
5360 have the proper signature.
5362 2002-04-26 Martin Baulig <martin@gnome.org>
5364 * driver.cs (LoadAssembly): If `assembly' contains any characters
5365 which are only valid in path names and not in assembly names
5366 (currently slash, backslash and point), use Assembly.LoadFrom ()
5367 instead of Assembly.Load () on the `assembly' (before iteration
5368 over the link_paths).
5370 2002-04-26 Martin Baulig <martin@gnome.org>
5372 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
5374 2002-04-25 Miguel de Icaza <miguel@ximian.com>
5376 * class.cs (Property): use the new typemanager.MemberLookup
5378 (TypeContainer.MemberLookup): Implement using the
5379 TypeManager.MemberLookup now.
5381 * typemanager.cs: Make MemberLookup a function of the TypeManager,
5382 and return MemberInfos, so that these can be used without an
5383 EmitContext (what we had before).
5385 2002-04-24 Miguel de Icaza <miguel@ximian.com>
5387 * expression.cs: Fix the case where the argument to params if the
5388 type of the params. I omitted handling this before. Fixed
5390 2002-04-22 Miguel de Icaza <miguel@ximian.com>
5392 * driver.cs: Call BootCorlib_PopulateCoreType
5394 * class.cs (Property.CheckBase): Check for properties only, not
5397 * interface.cs: Temporary hack: try/catch around the
5398 CustomAttributeBuilder, because I am getting an exception that I
5401 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
5402 types whose definitions are required to be there (attributes are
5403 defined before standard types).
5405 Compute definitions as we boot the various types, as they are used
5406 immediately (value_type class will need object_type, but if we do
5407 not initialize object_type, we will pass a null, which will let
5408 the runtime pick the System.Object from the existing corlib, which
5409 is not what we want).
5411 2002-04-22 Patrik Torstensson <totte@labs2.com>
5413 * cs-tokenizer.cs: fixed a number of trim() issues.
5415 2002-04-22 Ravi Pratap <ravi@ximian.com>
5417 * expression.cs (Argument.Type): Ensure that we return the correct
5418 type when we have out or ref parameters [in which case we
5421 2002-04-22 Miguel de Icaza <miguel@ximian.com>
5423 * class.cs (Property, Indexer): Allow extern modifier in there.
5425 * typemanager.cs (InitBaseTypes): Initializes object_type and
5426 value_type, since those will be used early on during the bootstrap
5427 process to compile corlib.
5429 (InitCoreTypes): Move code from here to InitBaseTypes.
5431 2002-04-21 Miguel de Icaza <miguel@ximian.com>
5433 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
5434 single-dimension arrays as using the ldlen opcode.
5436 Daniel Lewis discovered this optimization.
5438 * typemanager.cs: Add signature for System.Array::get_Length
5440 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
5442 * statement.cs: report the error when the foreach does not apply to an
5443 array nor a collection.
5445 2002-04-19 Miguel de Icaza <miguel@ximian.com>
5447 * expression.cs: Add implicit conversions to the operator ~.
5449 * constant.cs (DecimalConstant.Emit): Emit decimal value.
5451 * typemanager.cs: Locate the decimal constructor.
5453 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
5455 * attribute.cs: use the new property of TypeOf.
5456 * expression.cs: added 'get' property around typearg.
5458 These changes fix a build breaker reported by NickD. Is this the
5459 correct way to fix? If not, please, revert my changes and make it
5462 2002-04-17 Miguel de Icaza <miguel@ximian.com>
5464 * attribute.cs: Add support for typeof in attribute invocations.
5465 I am not sure that this is right though.
5467 2002-04-14 Duncan Mak <duncan@ximian.com>
5469 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
5470 Binary.Operator.Division case.
5472 2002-04-13 Ravi Pratap <ravi@ximian.com>
5474 * class.cs (DefineType): Ensure that we do a proper check on
5475 attribute types and also register it with the TypeManager.
5477 (TypeContainer.Targets): The default for attribute types is
5478 AttributeTargets.All.
5480 * attribute.cs (ApplyAttributes): Registering the attribute type
5481 is done elsewhere, not when we discover we have a Usage attribute.
5483 2002-04-12 Ravi Pratap <ravi@ximian.com>
5485 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
5486 and get rid of is_delegate parameter.
5488 * everywhere : update.
5490 2002-04-12 Ravi Pratap <ravi@ximian.com>
5492 * cs-parser.jay (compilation_unit): Revamp completely to use
5493 some new ideas that I got from Rhys' grammar to solve the problems
5494 with assembly level attributes.
5496 (outer_declaration): New grammar production.
5498 (attribute_sections): Add.
5500 (opt_attributes): Base on attribute_sections
5502 (namespace_declaration): Allow opt_attributes to tackle the case
5503 when we have assembly level attributes - we are clever in this
5506 * attribute.cs (ApplyAttributes): Do not worry about assembly
5507 attributes in the non-global context.
5509 * rootcontext.cs (AddGlobalAttributes): Go back to using this
5510 instead of SetGlobalAttributes.
5512 * class.cs, rootcontext.cs : Ensure we define and generate
5513 attribute types before anything else.
5515 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
5516 and flag the new error -20 for the case when the attribute type
5517 does not have valid targets specified. csc does not catch this.
5519 * ../errors/errors.txt : update for error # -20
5521 2002-04-11 Ravi Pratap <ravi@ximian.com>
5523 * support.cs (InternalParameters.ParameterModifier): Do some null
5524 checking and return sane values.
5526 * class.cs (Method.Define): If we are a PInvoke method, ensure
5527 that we are static and extern. Report error # 601
5529 * ../errors/cs0601.cs : Add test case for the above error.
5531 2002-04-07 Ravi Pratap <ravi@ximian.com>
5533 * rootcontext.cs (attribute_types): We need to keep type of
5534 all attribute types separately and emit code for them first.
5536 (RegisterAttribute) : Implement.
5538 * class.cs (DefineType): Check if the current Type is a custom
5539 attribute type and register it accordingly.
5541 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
5542 adding the first attribute twice and rename to
5544 (SetGlobalAttributes): this.
5546 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
5549 * attribute.cs (ApplyAttributes): Take an additional argument telling us
5550 if we are processing global arguments. Hmm, I am unsure of this.
5552 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
5554 * expression.cs: added static array of strings to avoid calling
5555 Enum.ToString () for Operator in Binary. Significant recover of
5558 2002-04-10 Miguel de Icaza <miguel@ximian.com>
5560 * class.cs (FindMembers): Allow the Builders of the various
5561 members to be null. If they are skip them. This only happens
5562 during the PInvoke declaration.
5564 2002-04-09 Miguel de Icaza <miguel@ximian.com>
5566 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
5567 failure, so we do not keep going afterwards.
5569 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
5570 wanted to pass `false' as the `is_delegate' argument. If this is
5571 the case, why not use delegate_type == null to mean `is_delegate =
5572 false' and anything else as is_delegate = true.
5574 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
5576 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
5577 code for the section, not the beginning of the tests.
5579 2002-04-08 Miguel de Icaza <miguel@ximian.com>
5581 * cfold.cs: Handle operator + (Enum x, Underlying x)
5583 * expression.cs (Binary): same. Warn about errors where we have
5584 Enum/Enum in operator + as well.
5586 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
5589 - added support for switch(bool)
5590 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
5591 - add TableSwitchEmit() to handle table-based switch statements
5593 2002-04-05 Ravi Pratap <ravi@ximian.com>
5595 * expression.cs (Invocation.OverloadResolve): Factor out code which
5596 does parameter compatibility checking with arguments so that we can
5597 re-use the code even from Delegate.VerifyApplicability
5599 (VerifyArgumentsCompat): Move above code here.
5601 * delegate.cs (VerifyApplicability): Get rid of duplicate code
5602 and instead make a call to the above method.
5604 2002-03-31 Ravi Pratap <ravi@ximian.com>
5606 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
5607 We use it to keep track of classes which are attribute types.
5609 2002-04-02 Miguel de Icaza <miguel@ximian.com>
5611 * delegate.cs (Delegate.Define): Correctly define the types in the
5612 presence of fixed and array parameters.
5614 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
5617 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
5618 include NonPublic after the first iteration.
5620 * class.cs (Indexer.CheckBase): Only check if both parents are
5623 * cs-parser.jay (accessor_body): If empty, set to null.
5625 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
5626 same code path here to resolve constants names that we did have in
5627 MemberAccess.DoResolve. There is too much code duplicated here.
5629 2002-04-01 Miguel de Icaza <miguel@ximian.com>
5631 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
5633 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
5636 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
5637 tokens, numbers and strings.
5639 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
5642 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
5643 asyncronous parameters and the regular parameters.
5645 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
5646 specify the target directory.
5648 * expression.cs: (This.DoResolve): Simplify
5649 (As.Emit): Optimize, do not generate IsInst if the expression is
5650 always of the given type.
5652 (Is.DoResolve): Bug fix, we were reporting both always/never for
5655 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
5656 creating too many unnecessary arrays.
5658 2002-03-31 Miguel de Icaza <miguel@ximian.com>
5660 * class.cs (EmitFieldInitializer): Use Assign expression to assign
5661 fields instead of rolling our own initializer. Takes care of all
5662 implicit conversions, and drops unnecessary static checks/argument.
5664 2002-03-31 Dick Porter <dick@ximian.com>
5666 * driver.cs: use the GetDirectories() return values properly, and
5667 use "/" as path separator.
5669 2002-03-30 Miguel de Icaza <miguel@ximian.com>
5671 * expression.cs (Unary): Optimize - - expr into expr.
5672 (Binary): Optimize a + (-b) into a -b.
5674 * codegen.cs (CodeGen): Made all methods static.
5676 2002-03-29 Miguel de Icaza <miguel@ximian.com>
5680 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
5681 TypeBuilder property.
5683 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
5686 * tree.cs: Removed the various RecordXXXX, and replaced with a
5687 single RecordDecl. Removed all the accessor methods, and just
5688 left a single access point Type
5690 * enum.cs: Rename DefineEnum to DefineType.
5692 * decl.cs: New abstract method `DefineType' used to unify the
5693 Defines for Enumerations, Interfaces, TypeContainers and
5696 (FindType): Moved LookupInterfaceOrClass here. Moved the
5697 LookupBaseClasses method that used to live in class.cs and
5698 interface.cs here, and renamed to FindType.
5700 * delegate.cs: Implement DefineType. Take advantage of the
5701 refactored pattern for locating the parent builder without taking
5702 the parent_builder argument (which we know does not work if we are
5703 nested, and triggering a toplevel definition).
5705 2002-03-28 Miguel de Icaza <miguel@ximian.com>
5707 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
5708 accessibility of a member has changed during override and report
5711 * class.cs (Method.Define, Property.Define): Only complain on
5712 overrides if the method is private, any other accessibility is
5713 fine (and since we just checked the permission is the same, we are
5716 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
5717 and elif are processed always. The other pre-processing
5718 directives are only processed if we are "taking" the path
5720 2002-03-29 Martin Baulig <martin@gnome.org>
5722 * class.cs (Method.Emit): Only emit symbolic debugging info if the
5723 current location is not Null.
5725 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
5726 a separate method so we can profile it.
5728 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
5729 `span.Seconds' are just seconds, but no minutes or hours.
5730 (MainDriver): Profile the CodeGen.SaveSymbols calls.
5732 2002-03-28 Miguel de Icaza <miguel@ximian.com>
5734 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
5735 Remove the gratuitous set of Final:
5737 // If an interface implementation, then we can set Final.
5738 if (((flags & MethodAttributes.Abstract) == 0) &&
5739 implementing.DeclaringType.IsInterface)
5740 flags |= MethodAttributes.Final;
5742 I do not know what I was smoking when I used that.
5745 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
5746 step into fixing the name resolution issues for delegates and
5747 unifying the toplevel name resolution.
5749 2002-03-28 Martin Baulig <martin@gnome.org>
5751 * class.cs (Method.Emit): If we have a symbol writer, call its
5752 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
5753 tell it about the current method.
5755 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
5756 writer that we're going to emit the first byte of IL code for a new
5757 statement (a new source line).
5758 (EmitContext.EmitTopBlock): If we have a symbol writer, call
5759 EmitContext.Mark() before emitting any code.
5761 * location.cs (SymbolDocument): Return null when we're Null.
5763 * statement.cs (Statement): Moved the `Location loc' variable here.
5764 (Statement.EmitBoolExpression): If we have a symbol writer, call
5765 ec.Mark() before emitting any code to tell it that we're at the
5766 beginning of a new statement.
5767 (StatementExpression): Added `Location' argument to the constructor.
5768 (Block): Added public readonly variable `StartLocation' and public
5769 variable `EndLocation'. The latter is to be set using SetEndLocation().
5770 (Block): Added constructor which takes a start and end location.
5771 (Block.SetEndLocation): New method. This sets the end location.
5772 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
5773 local variables we create.
5774 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
5775 each statement and do also mark the begin and end of the block.
5777 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
5778 tell it the current lexer.Location, use Location.Null for the end of the
5780 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
5781 current block, set its end location using SetEndLocation().
5782 (statement_expression): StatementExpression constructor now takes the
5783 lexer.Location as additional argument.
5784 (for_statement, declare_local_variables): Likewise.
5785 (declare_local_variables): When creating a new implicit block, use the
5786 new Block constructor and pass it the lexer.Location.
5788 2002-03-28 Miguel de Icaza <miguel@ximian.com>
5790 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
5791 members also on the parent interfaces recursively.
5793 2002-03-27 Miguel de Icaza <miguel@ximian.com>
5795 * report.cs: Use new formats, since Gonzalo finished the missing
5798 * expression.cs (Binary.ResolveOperator): added missing operator|
5799 operator& and operator^ for bool/bool.
5801 * cs-parser.jay: CheckDef now takes a Location argument that is
5802 used to report errors more precisly (instead of reporting the end
5803 of a definition, we try to track something which is a lot closer
5804 to the source of the problem).
5806 * cs-tokenizer.cs: Track global token use, so we can properly flag
5807 the use of #define/#undef after the first token has been seen.
5809 Also, rename the reportXXXX to Error_DescriptiveName
5811 * decl.cs (DeclSpace.IsTopLevel): Move property here from
5812 TypeContainer, so that Enum and Interface can use this too.
5814 * class.cs (TypeContainer.LookupInterfaceOrClass,
5815 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
5816 `builder' argument. Typically this was used to pass the parent
5817 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
5820 The problem is that a nested class could trigger the definition of
5821 a toplevel class, and the builder would be obviously wrong in that
5824 So we drop this argument, and we compute dynamically the
5825 TypeBuilder/ModuleBuilder (the correct information was available
5826 to us anyways from DeclSpace.Parent)
5828 * interface.cs (Interface.DefineInterface): Drop builder
5829 parameter cleanup like class.cs
5831 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
5834 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
5837 (Try.Emit): Propagate the returns value from the statement.
5839 (Return.Emit): Even if we are leavning
5841 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
5843 * modifiers.cs: Fix the computation of MethodAttributes flags.
5845 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
5847 * driver.cs: allow compilation of files that start with '/'.
5848 Add a default case when checking the argument of --target.
5850 2002-03-25 Miguel de Icaza <miguel@ximian.com>
5852 * interface.cs: Implement the same search algorithm for types in
5855 * delegate.cs: Do not allow multiple definition.
5857 * Recovered ChangeLog that got accidentally amputated
5859 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
5861 * rootcontext.cs: Load manually enum to allow core classes to
5862 contain enumerations.
5864 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
5865 Update to new static methods in TypeManager.
5867 * typemanager.cs (GetMethod, GetConstructor): Use our
5868 implementation of FindMembers to find the members, since during
5869 corlib compilation, the types are TypeBuilders and GetMethod and
5870 GetConstructor do not work.
5872 Make all methods in TypeManager static.
5874 (InitCodeHelpers): Split the functionality from
5875 the InitCodeTypes function.
5877 * driver.cs: Call InitCodeHelpers after we have populated the
5880 * cs-parser.jay (delegate_declaration): we did not used to compute
5881 the delegate name correctly for void delegates.
5883 2002-03-24 Miguel de Icaza <miguel@ximian.com>
5885 * rootcontext.cs (RootContext): Init the interface_resolve_order
5886 and type_container_resolve_order always.
5888 (ResolveCore, BootstrapCorlib_ResolveClass,
5889 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
5890 compiler when compiling with --nostdlib
5892 * class.cs (TypeContainer.DefineType): Check that our parent is
5893 not null. This test is most important when we are bootstraping
5896 * codegen.cs: Split out the symbol writing code.
5898 2002-03-25 Martin Baulig <martin@gnome.org>
5900 * driver.cs (-g): Made -g an alias for --debug.
5902 2002-03-24 Martin Baulig <martin@gnome.org>
5904 * codegen.cs (SymbolWriter): New public variable. Returns the
5905 current symbol writer.
5906 (CodeGen): Added `bool want_debugging_support' argument to the
5907 constructor. If true, tell the ModuleBuild that we want debugging
5908 support and ask it for the ISymbolWriter.
5909 (Save): If we have a symbol writer, call it's Close() method after
5910 saving the assembly.
5912 * driver.c (--debug): New command line argument to create a
5913 debugger information file.
5915 * location.cs (SymbolDocument): New public property. Returns an
5916 ISymbolDocumentWriter object for the current source file or null
5917 if we don't have a symbol writer.
5919 2002-03-21 Miguel de Icaza <miguel@ximian.com>
5921 * driver.cs (LoadAssembly): Correctly return when all the paths
5922 have been tried and not before.
5924 * statement.cs (Switch.Emit): return the actual coverage for this
5925 statement (returns/not-returns)
5927 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
5928 switch of the statement if we are the last switch section. That
5929 kills two problems: try/catch problems (we used to emit an empty
5930 nop at the end) and switch statements where all branches would
5933 2002-03-19 Miguel de Icaza <miguel@ximian.com>
5935 * driver.cs: Add default assemblies (the equivalent to the
5936 Microsoft CSC.RSP file)
5938 * cs-tokenizer.cs: When updating `cols and setting it to zero,
5939 also update tokens_seen and set it to false.
5941 * driver.cs: Implement --recurse for Mike.
5943 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
5944 correctly splitting out the paths.
5946 2002-03-18 Miguel de Icaza <miguel@ximian.com>
5948 * interface.cs (Interface.PopulateProperty): Instead of using
5949 `parent' as the declaration space for the set parameters, use
5952 * support.cs (InternalParameters): InternalParameters constructor
5953 takes a DeclSpace instead of a TypeContainer.
5955 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
5956 types are being initialized, load the address of it before calling
5959 (New): Provide a mechanism to disable the generation of local
5960 value type temporaries when the caller will be providing us with
5961 an address to store it.
5963 (ArrayCreation.EmitDynamicInitializers): Use it.
5965 2002-03-17 Miguel de Icaza <miguel@ximian.com>
5967 * expression.cs (Invocation.EmitArguments): Only probe for array
5968 property if there is more than one argument. Sorry about that.
5970 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
5973 * class.cs (Method.LabelParameters): Fix incorrect code path that
5974 prevented the `ParamArrayAttribute' from being applied to the
5977 2002-03-16 Miguel de Icaza <miguel@ximian.com>
5979 * support.cs (ReflectionParameters): Correctly compute whether the
5980 last argument is a params array. Fixes the problem with
5983 * typemanager.cs: Make the assemblies array always be non-null
5984 (empty, but non-null)
5986 * tree.cs (RecordDecl): New function that abstracts the recording
5987 of names. This reports error 101, and provides a pointer to the
5988 previous declaration. Fixes a crash in the compiler.
5990 * cs-parser.jay (constructor_declaration): Update to new grammar,
5991 and provide a constructor_body that can be empty.
5993 2002-03-15 Miguel de Icaza <miguel@ximian.com>
5995 * driver.cs: Add support for --resources.
5997 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
5998 Make all types for the various array helper methods be integer.
6000 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
6001 CheckState to ConvCast.
6003 (ConvCast): Now it takes a `checked' state argument, to avoid
6004 depending on the emit context for the conversion, and just using
6005 the resolve time setting.
6007 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
6008 instead of Invocation.EmitArguments. We do not emit the original
6009 arguments, instead we emit those which have been converted to
6010 unsigned int expressions.
6012 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
6014 * codegen.cs: ditto.
6016 * expression.cs (LocalVariableReference): Drop the use of the
6017 Store function that depended on the variable index.
6019 * statement.cs (VariableInfo): Drop the `Idx' property from this
6020 class, as this is not taking into account the indexes for
6021 temporaries tat we generate during the execution, getting the
6024 * class.cs: First emit class initializers, then call the parent
6027 * expression.cs (Binary): Fix opcode emision.
6028 (UnaryMutator.EmitCode): Support checked code generation
6030 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
6031 matches for events for both the Static and Instance scans,
6032 pointing to the same element. Fix that.
6034 2002-03-14 Miguel de Icaza <miguel@ximian.com>
6036 * rootcontext.cs (ResolveTree): Always set the
6037 interface_resolve_order, because nested interfaces will be calling
6040 * class.cs (GetInterfaceOrClass): Track the same resolution
6041 process used by TypeManager.LookupType. This fixes the nested
6042 type lookups in class declarations (separate path from
6045 (TypeContainer.DefineType): Also define nested interfaces.
6046 (TypeContainer.RegisterOrder): New public function used to
6047 register the order in which child interfaces need to be closed.
6049 Nested interfaces need to be closed after their parents have been
6052 * interface.cs (InterfaceAttr): Put all the logic for computing
6053 the interface attribute here.
6055 (DefineInterface): Register our interface order with the
6056 RootContext or with the TypeContainer depending on the case.
6058 2002-03-12 Miguel de Icaza <miguel@ximian.com>
6060 * cs-parser.jay: rework foreach statement to work with the new
6061 changes to the policy on SimpleNames.
6063 * report.cs: support Stacktrace on warnings as well.
6065 * makefile: drop --unsafe and /unsafe from the compile.
6067 2002-03-13 Ravi Pratap <ravi@ximian.com>
6069 * ecore.cs (StandardConversionExists): Modify to take an Expression
6070 as the first parameter. Ensure we do null -> reference type conversion
6073 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
6074 temporary Expression objects.
6076 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
6078 * interface.cs: workaround bug in method overloading resolution
6079 (there is already a bugzilla bug for it).
6081 2002-03-12 Miguel de Icaza <miguel@ximian.com>
6083 We could also solve this problem by having a separate path for
6084 performing type lookups, instead of DoResolve, we could have a
6085 ResolveType entry point, and only participating pieces of the
6086 production (simplename, deref, array) would implement this.
6088 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
6089 signal SimpleName to only resolve type names and not attempt to
6090 resolve anything else.
6092 * expression.cs (Cast): Set the flag.
6094 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
6096 * class.cs: Only report 108 if there is no `new' modifier.
6098 * cs-parser.jay: rework foreach statement to work with the new
6099 changes to the policy on SimpleNames.
6101 * report.cs: support Stacktrace on warnings as well.
6103 * makefile: drop --unsafe and /unsafe from the compile.
6105 2002-03-11 Miguel de Icaza <miguel@ximian.com>
6107 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
6108 lookups here, instead of doing that at parse time. This means
6109 that our grammar will not introduce `LocalVariableReferences' as
6110 expressions at this point. That solves the problem of code like
6118 This is only half the fix. The full fix requires parameters to
6119 also be handled in this way.
6121 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
6122 makes the use more obvious of the DeclSpace. The
6123 ec.TypeContainer.TypeBuilder is now only used to pull the
6126 My theory is that I can get rid of the TypeBuilder completely from
6127 the EmitContext, and have typecasts where it is used (from
6128 DeclSpace to where it matters).
6130 The only pending problem is that the code that implements Aliases
6131 is on TypeContainer, and probably should go in DeclSpace.
6133 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
6134 lookups here, instead of doing that at parse time. This means
6135 that our grammar will not introduce `LocalVariableReferences' as
6136 expressions at this point. That solves the problem of code like
6144 This is only half the fix. The full fix requires parameters to
6145 also be handled in this way.
6147 * class.cs (Property.DefineMethod): When implementing an interface
6148 method, set newslot, when implementing an abstract method, do not
6149 set the flag (before we tried never setting it, or always setting
6150 it, which is the difference).
6151 (Indexer.DefineMethod): same.
6152 (Method.DefineMethod): same.
6154 * ecore.cs: Only set the status used flag if we get back a Field.
6156 * attribute.cs: Temporary hack, so Paolo can keep working.
6158 2002-03-08 Ravi Pratap <ravi@ximian.com>
6160 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
6161 the unmanaged type in the case we have a MarshalAs attribute.
6163 (Resolve): Handle the case when we are parsing the special MarshalAs
6164 attribute [we need to store the unmanaged type to use later]
6166 * typemanager.cs (marshal_as_attr_type): Built in type for the
6167 MarshalAs Attribute.
6169 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
6170 on parameters and accordingly set the marshalling info.
6172 2002-03-09 Miguel de Icaza <miguel@ximian.com>
6174 * class.cs: Optimizing slightly by removing redundant code after
6175 we switched to the `NoTypes' return value.
6176 (Property.DefineMethod): use NoTypes here too.
6178 This fixes the bug I introduced in my last batch of changes.
6180 2002-03-05 Ravi Pratap <ravi@ximian.com>
6182 * tree.cs (RecordEnum): Add. We now keep track of enums too.
6184 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
6185 Enums since those are types too.
6187 * cs-parser.jay (enum_declaration): Record enums as we parse them.
6189 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
6190 thanks to a call during the lookup process.
6192 2002-03-07 Miguel de Icaza <miguel@ximian.com>
6194 * statement.cs (Foreach): Lots of work to accomodate a particular
6195 kind of foreach statement that I had not kept in mind. It is
6196 possible to have foreachs on classes that provide a GetEnumerator
6197 method that return objects that implement the "pattern" for using
6198 a foreach, there is no need to support GetEnumerator
6201 This is needed to compile nant.
6203 * decl.cs: Only report 114 if the member is not `Finalize' and if
6204 the warning level is at least 2.
6206 * class.cs: Moved the compare function from Method to
6209 (MethodSignature.InheritableMemberSignatureCompare): Add new
6210 filter function that is used to extract inheritable methods from a
6213 (Method.Define): Use the new `inheritable_method_signature_filter'
6216 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
6219 2002-03-06 Miguel de Icaza <miguel@ximian.com>
6221 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
6223 * cs-parser.jay: Add opt_semicolon to the interface declaration.
6225 * expression.cs: Pass location information to
6226 ConvertImplicitStandard.
6228 * class.cs: Added debugging code to track return values from
6231 2002-03-05 Miguel de Icaza <miguel@ximian.com>
6233 * expression.cs (Is.DoResolve): If either side of the `is' is an
6234 interface, do not flag the warning.
6236 * ecore.cs (ImplicitReferenceConversion): We need a separate test
6239 * report.cs: Allow for --fatal to be used with --probe.
6241 * typemanager.cs (NoTypes): Move the definition for the empty Type
6244 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
6246 (TypeContainer.DefineProxy): New function used to proxy to parent
6247 implementations when implementing interfaces.
6248 (TypeContainer.ParentImplements): used to lookup if our parent
6249 implements a public function that is required by an interface.
6250 (TypeContainer.VerifyPendingMethods): Hook this up.
6252 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
6253 `modules' and `assemblies' arraylists into arrays. We only grow
6254 these are the very early start up of the program, so this improves
6255 the speedof LookupType (nicely measured).
6257 * expression.cs (MakeByteBlob): Replaced unsafe code with
6258 BitConverter, as suggested by Paolo.
6260 * cfold.cs (ConstantFold.Binary): Special case: perform constant
6261 folding of string concatenation, but if either side is a string,
6262 and the other is not, then return null, and let the runtime use
6263 the concatenation on the string plus the object (using
6266 2002-03-04 Miguel de Icaza <miguel@ximian.com>
6268 Constant Folding has been implemented now.
6270 * expression.cs (Unary.Reduce): Do not throw an exception, catch
6271 the error instead on types that are not supported in one's
6274 * constant.cs (Constant and all children): New set of functions to
6275 perform implict and explicit conversions.
6277 * ecore.cs (EnumConstant): Implement the new functions to perform
6278 conversion by proxying to the child expression.
6280 * codegen.cs: (ConstantCheckState): Constant evaluation has its
6281 own separate setting that can not be turned off from the command
6282 line using --unchecked or --checked and is only controlled using
6283 the checked/unchecked statements and expressions. This setting is
6284 used by the constant folder to flag errors.
6286 * expression.cs (CheckedExpr, UncheckedExpr): Set the
6287 ConstantCheckState as well.
6289 During Resolve, they also have to flag the state, because the
6290 constant folder runs completely in the Resolve phase.
6292 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
6295 2002-03-01 Miguel de Icaza <miguel@ximian.com>
6297 * cfold.cs: New file, this file contains the constant folder.
6299 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
6300 argument to track whether we are using the resulting address to
6301 load or store a value and provide better error messages.
6303 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
6304 new AddressOf arguments.
6306 * statement.cs (Foreach.EmitCollectionForeach): Update
6308 * expression.cs (Argument.Emit): Call AddressOf with proper
6309 arguments to track usage.
6311 (New.DoEmit): Call AddressOf with new arguments.
6313 (Unary.Emit): Adjust AddressOf call.
6315 2002-03-01 Ravi Pratap <ravi@ximian.com>
6317 * cs-parser.jay (member_access): Change the case for pre-defined types
6318 to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
6321 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
6324 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
6325 essentially like methods and apply attributes like MethodImplOptions to them too.
6327 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
6330 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
6331 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
6334 * Update code everywhere accordingly.
6336 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
6338 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
6340 2002-02-28 Ravi Pratap <ravi@ximian.com>
6342 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
6343 try performing lookups against those instead of jumping straight into using
6344 the 'using' clauses.
6346 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
6348 (LookupType): Perform lookups in implicit parents too.
6350 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
6351 sequence as RootContext.LookupType.
6353 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
6354 the various cases of namespace lookups into this method.
6356 2002-03-01 Miguel de Icaza <miguel@ximian.com>
6358 * cs-parser.jay: Add support for [Attribute ()] (empty arguments
6359 in positional arguments)
6361 * class.cs (Operator): Update the AllowedModifiers to contain
6364 * cs-parser.jay: Update operator declaration to allow for the
6365 operator body to be empty.
6367 * cs-tokenizer.cs: Added '\u' unicode support in strings and hex
6370 2002-02-27 Miguel de Icaza <miguel@ximian.com>
6372 * class.cs (Method.Emit): Label parameters.
6374 * driver.cs: Return 1 or 0 as the program exit code.
6376 2002-02-26 Miguel de Icaza <miguel@ximian.com>
6378 * expression.cs: Special case the `null' object when trying to
6379 auto-compute the type, as anything can be explicitly converted to
6382 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
6383 spotting this Paolo.
6385 (Expression.ImplicitNumericConversion): Perform comparissions of
6386 the type using the underlying type in the case of an enumeration
6387 rather than using the enumeration type for the compare.
6389 Cope with the underlying == type case, which is not possible to
6392 (Expression.ConvertNumericExplicit): Perform comparissions of
6393 the type using the underlying type in the case of an enumeration
6394 rather than using the enumeration type for the compare.
6396 * driver.cs: If the user does not supply an extension, assume .exe
6398 * cs-parser.jay (if_statement): Rewrote so that we can track the
6399 location for the if statement.
6401 * expression.cs (Binary.ConstantFold): Only concat strings when
6402 the operation is "+", not everything ;-)
6404 * statement.cs (Statement.EmitBoolExpression): Take a location
6406 (If, While, Do): Track location.
6408 * expression.cs (Binary.ResolveOperator): In the object + string
6409 case, I was missing a call to ConvertImplicit
6411 2002-02-25 Ravi Pratap <ravi@ximian.com>
6413 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
6414 Location arguments. Ensure we use RootContext.LookupType to do our work
6415 and not try to do a direct Type.GetType and ModuleBuilder.GetType
6417 * interface.cs (PopulateMethod): Handle the type of the parameter being
6420 * expression.cs (Invocation.BetterFunction): Handle the case when we
6421 have a params method with no fixed arguments and a call is made with no
6424 2002-02-25 Miguel de Icaza <miguel@ximian.com>
6426 * cs-tokenizer.cs: Add support for the quote-escape-sequence in
6427 the verbatim-string-literal
6429 * support.cs (InternalParameters.ParameterModifier): handle null
6431 (InternalParameters.ParameterType): ditto.
6433 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
6434 duplicating the name of the variable parameter.
6435 (GetParameterByName): Fix bug where we were not looking up array
6436 paramters if they were the only present (thanks Paolo!).
6437 (GetParameterInfo): We only have an empty set of types if both
6438 fixed and array are set to null.
6439 (GetParameterInfo-idx): Handle FixedParameter == null
6441 * cs-parser.jay: Handle the case where there is no catch
6442 statements (missing null test).
6444 2002-02-22 Miguel de Icaza <miguel@ximian.com>
6446 * driver.cs (MainDriver): Be conservative on our command line
6449 Catch DirectoryNotFoundException when calling GetFiles.
6451 (SplitPathAndPattern): Used to split the input specification into
6452 a path and a pattern that we can feed to Directory.GetFiles.
6454 2002-02-21 Miguel de Icaza <miguel@ximian.com>
6456 * statement.cs (Fixed): Implement the last case of the Fixed
6457 statement (string handling).
6459 * expression.cs (StringPtr): New class used to return a char * to
6460 a string; Used by the Fixed statement.
6462 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
6464 * expression.cs (Binary.ResolveOperator): Remove redundant
6465 MemberLookup pn parent type.
6466 Optimize union call, we do not need a union if the types are the same.
6467 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
6470 Specialize the use of MemberLookup everywhere, instead of using
6471 the default settings.
6473 (StackAlloc): Implement stackalloc keyword.
6475 * cs-parser.jay: Add rule to parse stackalloc.
6477 * driver.cs: Handle /h, /help, /?
6479 * expression.cs (MakeByteBlob): Removed the hacks we had in place
6480 before we supported unsafe code.
6482 * makefile: add --unsafe to the self compilation of mcs.
6484 2002-02-20 Miguel de Icaza <miguel@ximian.com>
6486 * expression.cs (PointerArithmetic): New class that is used to
6487 perform pointer arithmetic.
6488 (Binary.Resolve): Handle pointer arithmetic
6489 Handle pointer comparission.
6490 (ArrayPtr): Utility expression class that is used to take the
6491 address of an array.
6493 (ElementAccess): Implement array access for pointers
6495 * statement.cs (Fixed): Implement fixed statement for arrays, we
6496 are missing one more case before we are done.
6498 * expression.cs (Indirection): Implement EmitAssign and set the
6499 ExprClass to Variable. This allows pointer dereferences to be
6500 treated as variables, and to have values assigned to them.
6502 * ecore.cs (Expression.StoreFromPtr): New utility function to
6503 store values dereferencing.
6505 2002-02-20 Ravi Pratap <ravi@ximian.com>
6507 * expression.cs (Binary.ResolveOperator): Ensure that we are
6508 not trying to operate on a void type - this fixes the reported
6511 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
6512 the parent implementation is sealed.
6514 * ../errors/cs0239.cs : Add.
6516 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
6518 * typemanager.cs (unverifiable_code_type): Corresponds to
6519 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
6520 which have unsafe code in them.
6522 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
6525 2002-02-19 Miguel de Icaza <miguel@ximian.com>
6527 * cs-tokenizer.cs: Add support for @"litreal strings"
6529 Make tokenizer accept pre-processor directives
6530 on any column (remove the old C-like limitation).
6532 * rootcontext.cs (EmitCode): Emit any global attributes.
6533 (AddGlobalAttributes): Used to keep track of assembly attributes.
6535 * attribute.cs (ApplyAttributes): Support AssemblyAttributes.

6539 2002-02-17 Miguel de Icaza <miguel@ximian.com>
6541 * expression.cs (Indirection): New helper class. Unary will
6542 create Indirection classes to be able to implement the
6543 IMemoryLocation interface on it.
6545 2002-02-16 Miguel de Icaza <miguel@ximian.com>
6547 * cs-parser.jay (fixed_statement): reference the right statement.
6549 * statement.cs (Fixed.Emit): Finish implementing the fixed
6550 statement for the &x case.
6552 2002-02-14 Miguel de Icaza <miguel@ximian.com>
6554 * class.cs (Property.Define, Method.Define): Remove newslot when
6557 * modifiers.cs: My use of NewSlot when `Abstract' was set was
6558 wrong. NewSlot should only be used if the `new' keyword is present.
6560 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
6561 locating our system dir. Sorry about this.
6563 2002-02-13 Miguel de Icaza <miguel@ximian.com>
6565 * driver.cs (GetSystemDir): Compute correctly the location of our
6566 system assemblies. I was using the compiler directory instead of
6567 the library directory.
6569 2002-02-13 Ravi Pratap <ravi@ximian.com>
6571 * expression.cs (BetterFunction): Put back in what Miguel commented out
6572 since it is the correct fix. The problem is elsewhere ;-)
6574 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
6575 parameters of the parms method are themselves compatible or not !
6577 (StandardConversionExists): Fix very dangerous bug where we were forgetting
6578 to check that a class implements an interface before saying that an implicit
6579 conversion was allowed. Use ImplementsInterface to do the checking.
6581 2002-02-13 Miguel de Icaza <miguel@ximian.com>
6583 * class.cs (Method.Define): Track whether we are an explicit
6584 implementation or not. And only call DefineMethodOverride if we
6585 are an explicit implementation.
6587 (Property.DefineMethod): Ditto.
6589 2002-02-11 Ravi Pratap <ravi@ximian.com>
6591 * expression.cs (BetterFunction): Catch hideous bug which was
6592 preventing us from detecting ambiguous calls due to implicit casts i.e
6595 2002-01-29 Miguel de Icaza <miguel@ximian.com>
6597 * support.cs (Pair): Remove un-needed method. I figured why I was
6598 getting the error in cs-parser.jay, the variable in a foreach loop
6599 is readonly, and the compiler does not really treat this as a variable.
6601 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
6602 instead of EQUALS in grammar.
6604 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
6606 * expression.cs (Unary.DoResolve): Check whether the argument is
6609 2002-01-28 Miguel de Icaza <miguel@ximian.com>
6611 * support.cs: Api for Pair to set a value. Despite the fact that
6612 the variables are public the MS C# compiler refuses to compile
6613 code that accesses the field if the variable is part of a foreach
6616 * statement.cs (Fixed): Begin implementation of the fixed
6619 (Block.AddVariable): Return the VariableInfo on success and null
6620 on failure instead of true/false.
6622 * cs-parser.jay (foreach): Catch errors on variables already
6623 defined (we were ignoring this value before) and properly unwind
6626 (fixed_statement): grammar for the fixed statement.
6628 2002-01-25 Miguel de Icaza <miguel@ximian.com>
6630 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
6631 pointer types to be incretemented.
6633 (SizeOf): Implement.
6635 * cs-parser.jay (pointer_member_access): Implement
6636 expr->IDENTIFIER production.
6638 * expression.cs (IndexerAccess.DoResolve, ArrayAccess.DoResolve,
6639 MemberAccess.DoResolve, Invocation.DoResolve): Check for pointers
6642 (Unary): Implement indirection.
6644 * ecore.cs (Expression.UnsafeError): Reports error 214 (pointer
6645 use in non-unsafe context).
6647 (SimpleName.DoResolve): Check for pointers in field access on safe
6650 (Expression.LoadFromPtr): Factor the load-indirect code in this
6651 function. This was duplicated in UnboxCast and ParameterReference
6653 2002-01-24 Miguel de Icaza <miguel@ximian.com>
6655 * expression.cs (ComposedCast): report an error if a pointer cast
6656 is used in a safe region.
6658 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
6659 pointer type casts in unsafe context.
6661 * codegen.cs (EmitContext): Set up IsUnsafe.
6663 * cs-parser.jay (non_expression_type): Add productions for pointer
6666 * expression.cs (Invocation.EmitCall): Remove chunk of buggy
6667 code. We should not use force into static mode if the method is
6668 not virtual. Fixes bug in MIS
6670 * statement.cs (Do.Emit, While.Emit, For.Emit,
6671 Statement.EmitBoolExpression): Add support to Do and While to
6672 propagate infinite loop as `I do return' semantics.
6674 Improve the For case to also test for boolean constants.
6676 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
6677 to the list of attributes we can add.
6679 Remove `EmitContext' argument.
6681 * class.cs (Method.Define): Apply parameter attributes.
6682 (Constructor.Define): Apply parameter attributes.
6683 (MethodCore.LabelParameters): Move here the core of labeling
6686 * support.cs (ReflectionParameters.ParameterModifier,
6687 InternalParameters.ParameterModifier): Use IsByRef on the type and
6688 only return the OUT bit for these parameters instead of in/out/ref
6691 This is because I miss-understood things. The ParameterInfo.IsIn
6692 and IsOut represent whether the parameter has the [In] and [Out]
6695 2002-01-22 Miguel de Icaza <miguel@ximian.com>
6697 * ecore.cs (FieldExpr.Emit): Release temporaries.
6699 * assign.cs (LocalTemporary.Release): new function.
6701 * codegen.cs (EmitContext.GetTemporaryStorage,
6702 EmitContext.FreeTemporaryStorage): Rework the way we deal with
6703 temporary storage. Now we can "put back" localbuilders when we
6706 2002-01-21 Miguel de Icaza <miguel@ximian.com>
6708 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
6709 need to make a copy of the variable to generate verifiable code.
6711 2002-01-19 Miguel de Icaza <miguel@ximian.com>
6713 * driver.cs: Compute dynamically the system directory.
6715 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
6716 Slower, but more generally useful. Used by the abstract
6717 registering implementation.
6719 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
6720 the rules for the special rule on Type/instances. First check if
6721 we have the same name, and if so, try that special static path
6722 rather than the instance path.
6724 2002-01-18 Miguel de Icaza <miguel@ximian.com>
6726 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
6729 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
6730 Enum, ValueType, Delegate or Array for non-corlib compiles.
6732 * cs-tokenizer.cs: Catch long identifiers (645)
6734 * typemanager.cs (IndexerPropetyName): Ravi never tested this
6737 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
6738 fix, we were returning too early, so we were not registering
6739 pending methods from abstract classes.
6741 Do not register pending methods if the class is abstract.
6743 * expression.cs (Conditional.DoResolve): Report circular implicit
6744 conversions when we neecd to compute it for conditional
6747 (Is.DoResolve): If the expression is always of the provided type,
6748 flag warning 183. If the expression can not ever be of the
6749 provided type flag warning 184.
6751 * class.cs: Catch 169 as well.
6753 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
6756 2002-01-18 Nick Drochak <ndrochak@gol.com>
6758 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.
6760 2002-01-17 Miguel de Icaza <miguel@ximian.com>
6762 * interface.cs: (PopulateMethod): Check for pointers being defined
6763 only if the unsafe context is active.
6764 (PopulateProperty): ditto.
6765 (PopulateIndexer): ditto.
6767 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
6768 specified. If pointers are present, make sure that they are
6769 present in an unsafe context.
6770 (Constructor, Constructor.Define): ditto.
6771 (Field, Field.Define): ditto.
6772 (Property, Property.Define): ditto.
6773 (Event, Event.Define): ditto.
6775 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
6776 hashtable if there are classes or structs defined.
6778 * expression.cs (LocalVariableReference.DoResolve): Simplify this
6779 code, as the constant resolution moved.
6781 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
6782 the metadata, so we can flag error 133.
6784 * decl.cs (MemberCore.UnsafeOK): New function to test that a
6785 pointer is being declared in an unsafe context.
6787 2002-01-16 Miguel de Icaza <miguel@ximian.com>
6789 * modifiers.cs (Modifiers.Check): Require a Location argument.
6790 Report error 227 for Unsafe use.
6792 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
6794 * statement.cs (For.Emit): If the test is null, then report that
6795 we do `return', as we wont reach anything afterwards.
6797 (Switch.SwitchGoverningType): Track the expression that matched
6800 * driver.cs: Allow negative numbers as an error code to flag.
6802 * cs-parser.jay: Handle 1551.
6804 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
6806 2002-01-15 Miguel de Icaza <miguel@ximian.com>
6808 * cs-parser.jay: Report 1518 (type declaration can only contain
6809 class, struct, interface, enum or delegate)
6811 (switch_label): Report 1523 (keywords `case' or `default' must
6814 (opt_switch_sections): Report 1522 (empty switch)
6816 * driver.cs: Report 1515 (response file specified multiple times)
6817 Report 1516 (Source file specified multiple times).
6819 * expression.cs (Argument.Resolve): Signal 1510
6821 (BaseAccess.Resolve, BaseIndexer.Resolve): Signal 1511 (base
6822 access not allowed in static code)
6824 2002-01-11 Ravi Pratap <ravi@ximian.com>
6826 * typemanager.cs (IsPointerType): Utility method which we are going
6829 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
6830 the object type, so we take care of that.
6832 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
6834 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
6835 added to non-params parameters :-)
6837 * typemanager.cs (CSharpName): Include 'void' type too.
6839 (void_ptr_type): Include in the set of core types.
6841 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
6844 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
6847 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
6848 completely forgotten about it.
6850 2002-01-10 Ravi Pratap <ravi@ximian.com>
6852 * cs-parser.jay (pointer_type): Add. This begins our implementation
6853 of parsing rules for unsafe code.
6855 (unsafe_statement): Implement.
6857 (embedded_statement): Modify to include the above.
6859 * statement.cs (Unsafe): Implement new class for unsafe blocks.
6861 * codegen.cs (EmitContext.InUnsafe): Add. This determines
6862 if the current context is an unsafe one.
6864 * cs-parser.jay (local_variable_pointer_type): Since local variable types
6865 are handled differently, we need separate rules for them.
6867 (local_variable_declaration): Update to use local_variable_pointer_type
6868 to allow variable declarations of unmanaged pointer types.
6870 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
6873 * ../errors/cs0214.cs : Add.
6875 2002-01-16 Nick Drochak <ndrochak@gol.com>
6877 * makefile: remove 'response' file when cleaning.
6879 2002-01-15 Miguel de Icaza <miguel@ximian.com>
6881 * cs-parser.jay: Report 1524.
6883 2002-01-14 Miguel de Icaza <miguel@ximian.com>
6885 * typemanager.cs (RegisterMethod): drop checking if we have
6886 registered this from here
6888 2002-01-12 Miguel de Icaza <miguel@ximian.com>
6890 * class.cs (Method.EmitDestructor): Implement calling our base
6893 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
6896 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
6897 this routine and will wrap the call in a try/catch block. Deal
6900 2002-01-11 Miguel de Icaza <miguel@ximian.com>
6902 * ecore.cs (Expression.MemberLookup): instead of taking a
6903 parameter `same_type' that was used to tell whether we could
6904 access private members we compute our containing type from the
6907 (FieldExpr): Added partial support for volatile fields. This does
6908 not work for volatile fields exposed from assemblies, as I can not
6909 figure out how to extract the modreq from it.
6911 Updated all the source files to use this.
6913 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
6914 because it is referenced by MemberLookup very often.
6916 2002-01-09 Ravi Pratap <ravi@ximian.com>
6918 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
6919 TypeBuilder.GetCustomAttributes to retrieve what we need.
6921 Get rid of redundant default_member_attr_type as this is the same as
6922 default_member_type which already exists.
6924 * interface.cs, attribute.cs : Update accordingly.
6926 2002-01-08 Miguel de Icaza <miguel@ximian.com>
6928 * typemanager.cs: Enable IndexerPropertyName again. It does not
6929 work for TYpeBuilders though. Ravi, can you please fix this?
6931 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
6933 * expression.cs (Argument.Emit): Handle the case of ref objects
6934 being passed to ref functions;
6936 (ParameterReference.EmitLoad): Loads the content of the pointer
6937 without dereferencing.
6939 2002-01-07 Miguel de Icaza <miguel@ximian.com>
6941 * cs-tokenizer.cs: Implemented the pre-processing expressions.
6943 2002-01-08 Ravi Pratap <ravi@ximian.com>
6945 * class.cs (Indexer.DefineMethod): Incorporate the interface
6946 type in the name of the method if we are doing explicit interface
6949 * expression.cs (ConversionExists): Remove as it is completely obsolete.
6951 (BetterConversion): Fix extremely trivial bug where we were referring to
6952 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
6955 * ../errors/bug16.cs : Add although we have fixed it.
6957 2002-01-07 Miguel de Icaza <miguel@ximian.com>
6959 * expression.cs (BaseIndexer): Begin implementation.
6961 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
6963 * cs-parser.jay (indexer_declarator): Use qualified_identifier
6964 production directly to remove a shift/reduce, and implement
6965 explicit interface implementation.
6967 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
6968 after a floating point suffix.
6970 * expression.cs (DoNumericPromotions): Improved the conversion for
6971 uint/uint. If we have a constant, we avoid doing a typecast to a
6974 * class.cs (Indexer): Implement explicit interface implementation
6977 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
6979 * class.cs: make the default instance constructor public and hidebysig.
6981 2001-01-03 Ravi Pratap <ravi@ximian.com>
6983 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
6984 so we can call it from elsewhere.
6986 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
6987 we emit it internally if the class has a defined indexer; otherwise the user
6988 emits it by decorating the class definition with the DefaultMemberAttribute.
6990 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
6991 attribute is not used on a type which defines an indexer.
6993 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
6994 character when we skip whitespace.
6996 * ../errors/cs0646.cs : Add.
6998 2002-01-03 Miguel de Icaza <miguel@ximian.com>
7000 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
7003 * makefile: Add practical target `mcs3.exe' which builds the third
7004 generation compiler.
7006 * expression.cs (New): Fix structures constructor calling.
7008 * class.cs (Property, Method, Indexer): Emit Final flag on the
7009 method if we are an interface implementation and we are not
7012 * ecore.cs (PropertyExpr): New public field `IsBase', tells
7013 whether this property is referencing a `base' method.
7015 * expression.cs (Invocation.EmitCall): take an extra argument:
7016 is_base, this is used to determine whether the `call' or
7017 `callvirt' opcode should be used.
7020 * delegate.cs: update EmitCall.
7022 * class.cs (Method.Define): Set NewSlot for the cases where we are
7023 not implementing an interface method.
7025 (Property.Define): ditto.
7027 2002-01-02 Miguel de Icaza <miguel@ximian.com>
7029 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
7030 'r'. Allows mcs to parse itself fully.
7032 2002-01-02 Ravi Pratap <ravi@ximian.com>
7034 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
7035 of the number of initializers that require the InitializeArray method.
7037 (CheckIndices): Store the Expression in all cases - not the plain value. Also
7038 update the above field where necessary.
7040 (MakeByteBlob): Update accordingly.
7042 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
7045 (EmitDynamicInitializers): Update in accordance with the new optimization.
7047 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
7048 same OpCode applies.
7050 * cs-parser.jay : Fix some glaring errors I introduced.
7052 2002-01-01 Ravi Pratap <ravi@ximian.com>
7054 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
7055 so that we can check for name clashes there too.
7057 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
7058 for interface indexers.
7060 * interfaces.cs (Define): Emit the default member attribute.
7062 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
7063 variable was being referred to while setting the value ;-)
7065 2002-01-01 Miguel de Icaza <miguel@ximian.com>
7067 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
7068 byte-by-byte information when we know the data is zero.
7070 Make the block always a multiple of 4, because
7071 DefineInitializedData has a bug.
7073 * assign.cs: Fix, we should assign from the temporary, not from
7076 * expression.cs (MakeByteBlob): Fix my incorrect code.
7078 2001-12-31 Miguel de Icaza <miguel@ximian.com>
7080 * typemanager.cs (EnumToUnderlying): This function is used to get
7081 the underlying type from an enumeration, because it does not
7084 * constant.cs: Use the I4_S form for values between -128 and 127.
7086 * statement.cs (Block.LookupLabel): Looks up a label.
7087 (Block): Drop support for labeled blocks.
7089 (LabeledStatement): New kind of statement that represents a label
7092 (Goto): Finally implement this bad boy.
7094 * cs-parser.jay: Update to reflect new mechanism to implement
7097 2001-12-30 Miguel de Icaza <miguel@ximian.com>
7099 * codegen.cs (EmitContext.This): a codegen property that keeps the
7100 a single instance of this instead of creating many different this
7103 * delegate.cs (Delegate.DoResolve): Update to use the property;
7105 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
7107 * expression.cs (BaseAccess.DoResolve): Ditto.
7109 2001-12-29 Ravi Pratap <ravi@ximian.com>
7111 * typemanager.cs (methodimpl_attr_type): Add to hold the type
7112 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
7114 (InitCoreTypes): Update accordingly.
7116 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
7117 so we can quickly store the state.
7119 (ApplyAttributes): Set the correct implementation flags
7120 for InternalCall methods.
7122 2001-12-29 Miguel de Icaza <miguel@ximian.com>
7124 * expression.cs (EmitCall): if a method is not virtual, then do
7125 not use callvirt on it.
7127 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
7128 user defined stuff) requires the use of stobj, which takes an
7129 address on the stack instead of an array and an index. So emit
7130 the Ldelema operation for it.
7132 (EmitStoreOpcode): Use stobj for valuetypes.
7134 (UnaryMutator.EmitCode): Use the right 1 value depending on
7135 whether we are dealing with int64/uint64, float or doubles.
7137 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
7138 constructors that I implemented last night.
7140 (Constructor.IsDefault): Fix to work properly for static
7143 * cs-parser.jay (CheckDef): report method signature errors.
7144 Update error number 103 to be 132.
7146 * decl.cs: New AdditionResult enumeration value: MethodExists.
7147 Although we do this check for methods later on in the semantic
7148 analysis, catching repeated default constructors is so easy that
7149 we catch these here.
7151 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
7154 (ParameterReference.EmitAssign, Emit): handle
7157 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
7158 (ArrayAccess.EmitStoreOpcode): ditto.
7160 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
7162 * expression.cs (MakeByteBlob): Complete all the missing types
7163 (uint, short, ushort, byte, sbyte)
7165 * class.cs: Only init instance field initializers on instance
7168 Rename `constructors' to instance_constructors.
7170 (TypeContainer.AddConstructor): Only add constructors to the list
7171 if it is not static.
7173 Make sure that we handle default_static_constructor independently
7174 everywhere where we handle instance_constructors
7176 2001-12-28 Miguel de Icaza <miguel@ximian.com>
7178 * class.cs: Do not lookup or create a base initializer for a
7181 (ConstructorInitializer.Resolve): use the proper type to lookup
7184 * cs-parser.jay: Report error 1585 (modifiers between type and name).
7186 * enum.cs, interface.cs: Remove CloseType, this is taken care by
7189 * decl.cs: CloseType is now an virtual method, the default
7190 implementation just closes this type.
7192 2001-12-28 Ravi Pratap <ravi@ximian.com>
7194 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
7195 to PreserveSig by default. Also emit HideBySig on such methods.
7197 Basically, set the defaults to standard values.
7199 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
7200 argument, if candidate is better, it can't be worse than the best !
7202 (Invocation): Re-write bits to differentiate between methods being
7203 applicable in their expanded form and their normal form - for params
7206 Get rid of use_standard everywhere as only standard conversions are allowed
7207 in overload resolution.
7209 More spec conformance.
7211 2001-12-27 Miguel de Icaza <miguel@ximian.com>
7213 * driver.cs: Add --timestamp, to see where the compiler spends
7216 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
7217 `this' in static code.
7219 (SimpleName.DoResolve): Implement in terms of a helper function
7220 that allows static-references to be passed upstream to
7223 (Expression.ResolveWithSimpleName): Resolve specially simple
7224 names when called by MemberAccess to implement the special
7227 (Expression.ImplicitReferenceConversion): Handle conversions from
7228 Null to reference types before others, as Null's type is
7231 * expression.cs (Invocation.EmitCall): Handle the special case of
7232 calling methods declared on a reference type from a ValueType
7233 (Base classes System.Object and System.Enum)
7235 (MemberAccess.Resolve): Only perform lookups on Enumerations if
7236 the left hand side is a TypeExpr, not on every enumeration.
7238 (Binary.Resolve): If types are reference types, then do a cast to
7239 object on operators != and == of both arguments.
7241 * typemanager.cs (FindMembers): Extract instance and static
7242 members if requested.
7244 * interface.cs (PopulateProperty): Use void_type instead of null
7245 as the return type for the setter method.
7247 (PopulateIndexer): ditto.
7249 2001-12-27 Ravi Pratap <ravi@ximian.com>
7251 * support.cs (ReflectionParameters): Fix minor bug where we
7252 were examining the wrong parameter for the ParamArray attribute.
7254 Cope with requests for the type of the parameter at position
7255 greater than the params parameter's. We now return the element
7256 type of the params array as that makes more sense.
7258 * expression.cs (Invocation.IsParamsMethodApplicable): Update
7259 accordingly as we no longer have to extract the element type
7262 (Invocation.OverloadResolve): Update.
7264 2001-12-27 Miguel de Icaza <miguel@ximian.com>
7266 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
7267 against IEnumerator, test whether the return value is a descendant
7268 of the IEnumerator interface.
7270 * class.cs (Indexer.Define): Use an auxiliary method to implement
7271 the other bits of the method definition. Begin support for
7272 explicit interface implementation.
7274 (Property.DefineMethod): Use TypeManager.void_type instead of null
7275 for an empty return value.
7277 2001-12-26 Miguel de Icaza <miguel@ximian.com>
7279 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
7280 dealing with a FieldExpr which is composed of a FieldBuilder, in
7281 the code path we did extract the constant, but we should have
7282 obtained the underlying value to be able to cast it (otherwise we
7283 end up in an infinite loop, this is what Ravi was running into).
7285 (ArrayCreation.UpdateIndices): Arrays might be empty.
7287 (MemberAccess.ResolveMemberAccess): Add support for section
7288 14.5.4.1 that deals with the special case of E.I when E is a type
7289 and something else, that I can be a reference to a static member.
7291 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
7292 handle a particular array type to create byte blobs, it is just
7293 something we dont generate byteblobs for.
7295 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
7298 * location.cs (Push): remove the key from the hashtable that we
7299 are about to add. This happens for empty files.
7301 * driver.cs: Dispose files after we have parsed them.
7303 (tokenize): new function that only runs the tokenizer on its
7304 input, for speed testing.
7306 2001-12-26 Ravi Pratap <ravi@ximian.com>
7308 * class.cs (Event.Define): Define the private field only if there
7309 are no accessors defined.
7311 * expression.cs (ResolveMemberAccess): If there is no associated
7312 field with the event, that means we have an event defined with its
7313 own accessors and we should flag error cs0070 since transforming
7314 ourselves into a field is not valid in that case.
7316 * ecore.cs (SimpleName.DoResolve): Same as above.
7318 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
7319 and charset to sane values.
7321 2001-12-25 Ravi Pratap <ravi@ximian.com>
7323 * assign.cs (DoResolve): Perform check on events only if they
7324 are being accessed outside the declaring type.
7326 * cs-parser.jay (event_declarations): Update rules to correctly
7327 set the type of the implicit parameter etc.
7329 (add_accessor, remove_accessor): Set current local parameters.
7331 * expression.cs (Binary): For delegate addition and subtraction,
7332 cast the return value from the method into the appropriate delegate
7335 2001-12-24 Ravi Pratap <ravi@ximian.com>
7337 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
7338 of these as the workaround is unnecessary.
7340 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
7341 delegate data - none of that is needed at all.
7343 Re-write bits to extract the instance expression and the delegate method
7346 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
7349 * attribute.cs (ApplyAttributes): New method to take care of common tasks
7350 of attaching attributes instead of duplicating code everywhere.
7352 * everywhere : Update code to do attribute emission using the above method.
7354 2001-12-23 Miguel de Icaza <miguel@ximian.com>
7356 * expression.cs (IsParamsMethodApplicable): if there are not
7357 parameters, return immediately.
7359 * ecore.cs: The 0 literal can be implicity converted to an enum
7362 (SimpleName.DoResolve): First lookup the type, then lookup the
7365 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
7366 want to get its address. If the InstanceExpression is not
7367 addressable, store the result in a temporary variable, then get
7370 * codegen.cs: Only display 219 errors on warning level or above.
7372 * expression.cs (ArrayAccess): Make it implement the
7373 IMemoryLocation interface.
7375 (Binary.DoResolve): handle the operator == (object a, object b)
7376 and operator != (object a, object b) without incurring into a
7377 BoxedCast (because 5 != o should never be performed).
7379 Handle binary enumerator operators.
7381 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
7382 value type, otherwise use Ldelem_ref.
7384 Use precomputed names;
7386 (AddressOf): Implement address of
7388 * cs-parser.jay (labeled_statement): Fix recursive block
7389 addition by reworking the production.
7391 * expression.cs (New.DoEmit): New has a special case:
7393 If we are dealing with a ValueType, we have a few
7394 situations to deal with:
7396 * The target of New is a ValueType variable, that is
7397 easy, we just pass this as the variable reference
7399 * The target of New is being passed as an argument,
7400 to a boxing operation or a function that takes a
7403 In this case, we need to create a temporary variable
7404 that is the argument of New.
7407 2001-12-23 Ravi Pratap <ravi@ximian.com>
7409 * rootcontext.cs (LookupType): Check that current_type is not null before
7410 going about looking at nested types.
7412 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
7413 not implement the IAssignMethod interface any more.
7415 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
7416 where we tranform them into FieldExprs if they are being resolved from within
7419 * ecore.cs (SimpleName.DoResolve): Do the same here.
7421 * assign.cs (DoResolve, Emit): Clean up code considerably.
7423 * ../errors/bug10.cs : Add.
7425 * ../errors/cs0070.cs : Add.
7427 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
7429 * assign.cs : Get rid of EventIsLocal everywhere.
7431 2001-12-23 Miguel de Icaza <miguel@ximian.com>
7433 * ecore.cs (ConvertIntLiteral): finished the implementation.
7435 * statement.cs (SwitchLabel): Convert the value we are using as a
7436 key before looking up the table.
7438 2001-12-22 Miguel de Icaza <miguel@ximian.com>
7440 * codegen.cs (EmitTopBlock): Require a Location argument now.
7442 * cs-parser.jay (constructor_declarator): We need to setup
7443 current_local_parameters before we parse the
7444 opt_constructor_initializer, to allow the variables to be bound
7445 to the constructor arguments.
7447 * rootcontext.cs (LookupType): First lookup nested classes in our
7448 class and our parents before we go looking outside our class.
7450 * expression.cs (ConstantFold): Extract/debox the values at the
7453 * rootcontext.cs (EmitCode): Resolve the constants first before we
7454 resolve the types. This is not really needed, but it helps debugging.
7456 * statement.cs: report location.
7458 * cs-parser.jay: pass location to throw statement.
7460 * driver.cs: Small bug fix.
7462 * report.cs: Updated format to be 4-zero filled digits.
7464 2001-12-22 Ravi Pratap <ravi@ximian.com>
7466 * expression.cs (CheckIndices): Fix minor bug where the wrong
7467 variable was being referred to ;-)
7469 (DoEmit): Do not call EmitStaticInitializers when the
7470 underlying type is System.Object.
7472 2001-12-21 Ravi Pratap <ravi@ximian.com>
7474 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
7475 and do the usual workaround for SRE.
7477 * class.cs (MyEventBuilder.EventType): New member to get at the type
7478 of the event, quickly.
7480 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
7482 * assign.cs (Assign.DoResolve): Handle the case when the target
7483 is an EventExpr and perform the necessary checks.
7485 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
7488 (SimpleName.MemberStaticCheck): Include check for EventExpr.
7490 (EventExpr): Set the type in the constructor itself since we
7491 are meant to be born fully resolved.
7493 (EventExpr.Define): Revert code I wrote earlier.
7495 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
7496 instance expression is null. The instance expression is a This in that case
7497 or a null, depending on whether it is a static method or not.
7499 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
7500 refers to more than one method.
7502 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
7503 and accordingly flag errors.
7505 2001-12-21 Miguel de Icaza <miguel@ximian.com>
7507 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
7509 2001-12-22 Miguel de Icaza <miguel@ximian.com>
7511 * location.cs (ToString): Provide useful rutine.
7513 2001-12-21 Miguel de Icaza <miguel@ximian.com>
7515 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
7516 objects, return the actual integral boxed.
7518 * statement.cs (SwitchLabel): define an ILLabel for each
7521 (Switch.CheckSwitch): If the value is a Literal, extract
7522 the underlying literal.
7524 Also in the unused hashtable we had, add the SwitchLabel so we can
7525 quickly look this value up.
7527 * constant.cs: Implement a bunch of new constants. Rewrite
7528 Literal based on this. Made changes everywhere to adapt to this.
7530 * expression.cs (Expression.MakeByteBlob): Optimize routine by
7531 dereferencing array only once, and also copes with enumrations.
7533 bytes are two bytes wide, not one.
7535 (Cast): Perform constant conversions.
7537 * ecore.cs (TryImplicitIntConversion): Return literals instead of
7538 wrappers to the literals here.
7540 * expression.cs (DoNumericPromotions): long literals can converted
7541 to ulong implicity (this is taken care of elsewhere, but I was
7544 * ecore.cs (Expression.Literalize): Make the return type Literal,
7545 to improve type checking.
7547 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
7549 2001-12-20 Miguel de Icaza <miguel@ximian.com>
7551 * literal.cs: Revert code from ravi that checked the bounds. The
7552 bounds are sane by the definition of the type itself.
7554 * typemanager.cs: Fix implementation of ImplementsInterface. We
7555 need to actually look up in our parent hierarchy for interfaces
7558 * const.cs: Use the underlying type for enumerations
7560 * delegate.cs: Compute the basename for the delegate creation,
7561 that should fix the delegate test case, and restore the correct
7562 Type Lookup semantics in rootcontext
7564 * rootcontext.cs: Revert Ravi's last patch. The correct way of
7565 referencing a nested type with the Reflection API is using the "+"
7568 * cs-parser.jay: Do not require EOF token at the end.
7570 2001-12-20 Ravi Pratap <ravi@ximian.com>
7572 * rootcontext.cs (LookupType): Concatenate type names with
7573 a '.' instead of a '+' The test suite passes again.
7575 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
7576 field of the enumeration.
7578 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
7579 the case when the member is an EventExpr.
7581 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
7582 static has an associated instance expression.
7584 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
7586 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
7588 * class.cs (Event.Define): Register event and perform appropriate checks
7591 We define the Add and Remove methods even if the use provides none because
7592 in that case, we provide default implementations ourselves.
7594 Define a private field of the type of the event. This is done by the CSC compiler
7595 and we should be doing it too ;-)
7597 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
7598 More methods we use in code we generate.
7600 (multicast_delegate_type, delegate_type): Two separate types since the distinction
7603 (InitCoreTypes): Update accordingly for the above.
7605 * class.cs (Event.Emit): Generate code for default accessors that we provide
7607 (EmitDefaultMethod): Do the job in the above.
7609 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
7612 2001-12-20 Miguel de Icaza <miguel@ximian.com>
7614 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
7615 builders even if we were missing one.
7617 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
7618 pass the Basename as our class name instead of the Name. The
7619 basename will be correctly composed for us.
7621 * parameter.cs (Paramters): Now takes a Location argument.
7623 * decl.cs (DeclSpace.LookupType): Removed convenience function and
7624 make all the code call directly LookupType in RootContext and take
7625 this chance to pass the Location information everywhere.
7627 * Everywhere: pass Location information.
7629 2001-12-19 Miguel de Icaza <miguel@ximian.com>
7631 * class.cs (Constructor.Define): Updated way of detecting the
7632 length of the parameters.
7634 (TypeContainer.DefineType): Use basename as the type name for
7637 (TypeContainer.Define): Do not recursively define types here, as
7638 definition is taken care in order by the RootContext.
7640 * tree.cs: Keep track of namespaces in a per-file basis.
7642 * parameter.cs (Parameter.ComputeSignature): Update to use
7645 (Parameters.GetSignature): ditto.
7647 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
7648 instead of a TypeContainer.
7650 (Interface.SemanticAnalysis): Use `this' instead of our parent to
7651 resolve names. Because we need to be resolve in our context, not
7654 * driver.cs: Implement response files.
7656 * class.cs (TypeContainer.DefineType): If we are defined, do not
7659 (Event.Emit): Emit the code for add/remove handlers.
7660 (Event.Define): Save the MethodBuilders for add/remove.
7662 * typemanager.cs: Use pair here too.
7664 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
7665 DictionaryEntry requires the first argument to be non-null.
7667 (enum_declaration): Compute full name for registering the
7670 (delegate_declaration): Instead of using
7671 formal_parameter_list, use opt_formal_parameter_list as the list
7674 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
7675 (EventParsing): New property that controls whether `add' and
7676 `remove' are returned as tokens or identifiers (for events);
7678 2001-12-19 Ravi Pratap <ravi@ximian.com>
7680 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
7681 use MyEventBuilder only and let it wrap the real builder for us.
7683 (MyEventBuilder): Revamp constructor etc.
7685 Implement all operations that we perform on EventBuilder in precisely the same
7688 (FindMembers): Update to use the EventBuilder member.
7690 (Event.Emit): Update accordingly.
7692 2001-12-18 Ravi Pratap <ravi@ximian.com>
7694 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
7695 by calling the appropriate methods.
7697 (GetCustomAttributes): Make stubs as they cannot possibly do anything
7700 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
7702 2001-12-17 Ravi Pratap <ravi@ximian.com>
7704 * delegate.cs (Delegate.Populate): Check that the return type
7705 and various parameters types are indeed accessible.
7707 * class.cs (Constructor.Define): Same here.
7709 (Field.Define): Ditto.
7711 (Event.Define): Ditto.
7713 (Operator.Define): Check that the underlying Method defined itself
7714 correctly - so it's MethodBuilder should not be null.
7716 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
7717 expression happens to be null.
7719 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
7720 members but as of now we don't seem to be able to do anything really useful with it.
7722 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
7723 not the EventBuilder.
7725 2001-12-18 Miguel de Icaza <miguel@ximian.com>
7727 * cs-tokenizer.cs: Add support for defines.
7728 Add support for #if, #elif, #else, #endif
7730 (eval_var): evaluates a variable.
7731 (eval): stubbed for evaluating functions.
7733 * cs-parser.jay: Pass the defines information
7735 * driver.cs: Add --define command line option.
7737 * decl.cs: Move MemberCore here.
7739 Make it the base class for DeclSpace. This allows us to catch and
7740 report 108 and 109 for everything now.
7742 * class.cs (TypeContainer.Define): Extract all the members
7743 before populating and emit the warning 108 (new keyword required
7744 to override) instead of having each member implement this.
7746 (MemberCore.Define): New abstract method, we will be using this in
7747 the warning reporting engine in Populate.
7749 (Operator.Define): Adjust to new MemberCore protocol.
7751 * const.cs (Const): This does not derive from Expression, it is a
7752 temporary object we use to create fields, it is a MemberCore.
7754 * class.cs (Method.Define): Allow the entry point to be in a
7757 * driver.cs: Rewrite the argument handler to clean it up a bit.
7759 * rootcontext.cs: Made it just an auxiliary namespace feature by
7760 making everything static.
7762 * driver.cs: Adapt code to use RootContext type name instead of
7765 * delegate.cs: Remove RootContext argument.
7767 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
7770 * class.cs (Event.Define): The lookup can fail.
7772 * cs-tokenizer.cs: Begin implementation of pre-procesor.
7774 * expression.cs: Resolve the this instance before invoking the code.
7776 2001-12-17 Miguel de Icaza <miguel@ximian.com>
7778 * cs-parser.jay: Add a production in element_access that allows
7779 the thing to become a "type" reference. This way we can parse
7780 things like "(string [])" as a type.
7782 Note that this still does not handle the more complex rules of
7786 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
7788 * ecore.cs: (CopyNewMethods): new utility function used to
7789 assemble the list of methods from running FindMembers.
7791 (MemberLookup): Rework FindMembers so that
7793 2001-12-16 Miguel de Icaza <miguel@ximian.com>
7795 * class.cs (TypeContainer): Remove Delegates who fail to be
7798 * delegate.cs (Populate): Verify that we dont get null return
7799 values. TODO: Check for AsAccessible.
7801 * cs-parser.jay: Use basename to emit error 574 (destructor should
7802 have the same name as container class), not the full name.
7804 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
7805 possible representation.
7807 Also implements integer type suffixes U and L.
7809 2001-12-15 Miguel de Icaza <miguel@ximian.com>
7811 * expression.cs (ArrayCreation.DoResolve): We need to do the
7812 argument resolution *always*.
7814 * decl.cs: Make this hold the namespace. Hold the root context as
7816 (LookupType): Move here.
7818 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
7820 * location.cs (Row, Name): Fixed the code, it was always returning
7821 references to the first file.
7823 * interface.cs: Register properties defined through interfaces.
7825 * driver.cs: Add support for globbing on the command line
7827 * class.cs (Field): Make it derive from MemberCore as well.
7830 2001-12-15 Ravi Pratap <ravi@ximian.com>
7832 * class.cs (Event::Define): Check that the type of the event is a delegate
7833 type else flag error #66.
7835 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
7838 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
7839 values of EntryPoint, CharSet etc etc.
7841 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
7843 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
7844 be null and we should ignore this. I am not sure if this is really clean. Apparently,
7845 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
7846 which needs this to do its work.
7848 * ../errors/cs0066.cs : Add.
7850 2001-12-14 Miguel de Icaza <miguel@ximian.com>
7852 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
7855 * class.cs: (MethodSignature.MethodSignature): Removed hack that
7856 clears out the parameters field.
7857 (MemberSignatureCompare): Cleanup
7859 (MemberCore): New base class used to share code between MethodCore
7862 (RegisterRequiredImplementations) BindingFlags.Public requires
7863 either BindingFlags.Instace or Static. Use instance here.
7865 (Property): Refactored code to cope better with the full spec.
7867 * parameter.cs (GetParameterInfo): Return an empty array instead
7870 * class.cs (Property): Abstract or extern properties have no bodies.
7872 * parameter.cs (GetParameterInfo): return a zero-sized array.
7874 * class.cs (TypeContainer.MethodModifiersValid): Move all the
7875 method modifier validation to the typecontainer so we can reuse
7878 (MethodCore.ParameterTypes): return an empty sized array of types.
7880 (Property.Define): Test property modifier validity.
7882 Add tests for sealed/override too.
7884 (Method.Emit): abstract or extern methods have no bodies.
7886 2001-12-14 Ravi Pratap <ravi@ximian.com>
7888 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
7891 (Method::Define, ::Emit): Modify accordingly.
7893 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
7895 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
7897 * makefile: Pass in /unsafe.
7899 2001-12-13 Miguel de Icaza <miguel@ximian.com>
7901 * class.cs (MakeKey): Kill routine.
7903 * class.cs (TypeContainer.Define): Correctly define explicit
7904 method implementations (they require the full interface name plus
7907 * typemanager.cs: Deply the PtrHashtable here and stop using the
7908 lame keys. Things work so much better.
7910 This of course broke everyone who depended on `RegisterMethod' to
7911 do the `test for existance' test. This has to be done elsewhere.
7913 * support.cs (PtrHashtable): A hashtable that avoid comparing with
7914 the object stupid Equals method (because, that like fails all over
7915 the place). We still do not use it.
7917 * class.cs (TypeContainer.SetRequiredInterface,
7918 TypeContainer.RequireMethods): Killed these two routines and moved
7919 all the functionality to RegisterRequiredImplementations.
7921 (TypeContainer.RegisterRequiredImplementations): This routine now
7922 registers all the implementations required in an array for the
7923 interfaces and abstract methods. We use an array of structures
7924 which can be computed ahead of time to reduce memory usage and we
7925 also assume that lookups are cheap as most classes will not
7926 implement too many interfaces.
7928 We also avoid creating too many MethodSignatures.
7930 (TypeContainer.IsInterfaceMethod): Update and optionally does not
7931 clear the "pending" bit if we find that there are problems with
7934 (TypeContainer.VerifyPendingMethods): Update to report errors of
7935 methods that look like implementations but are not.
7937 (TypeContainer.Define): Add support for explicit interface method
7940 2001-12-12 Miguel de Icaza <miguel@ximian.com>
7942 * typemanager.cs: Keep track of the parameters here instead of
7943 being a feature of the TypeContainer.
7945 * class.cs: Drop the registration of parameters here, as
7946 InterfaceMethods are also interface declarations.
7948 * delegate.cs: Register methods with the TypeManager not only with
7949 the TypeContainer. This code was buggy.
7951 * interface.cs: Full registation here.
7953 2001-12-11 Miguel de Icaza <miguel@ximian.com>
7955 * expression.cs: Remove reducer for binary expressions, it can not
7958 * const.cs: Put here the code that used to go into constant.cs
7960 * constant.cs: Put here the code for constants, this is a new base
7963 * literal.cs: Make Literal derive from Constant.
7965 2001-12-09 Miguel de Icaza <miguel@ximian.com>
7967 * statement.cs (Return.Emit): Report error 157 if the user
7968 attempts to return from a finally block.
7970 (Return.Emit): Instead of emitting a return, jump to the end of
7973 * codegen.cs (EmitContext): ReturnValue, ReturnLabel: new
7974 LocalBuilder to store the result of the function. ReturnLabel is
7975 the target where we jump.
7978 2001-12-09 Radek Doulik <rodo@ximian.com>
7980 * cs-parser.jay: remember alias in current namespace
7982 * ecore.cs (SimpleName::DoResolve): use aliases for types or
7985 * class.cs (LookupAlias): lookup alias in my_namespace
7987 * namespace.cs (UsingAlias): add alias, namespace_or_type pair to
7989 (LookupAlias): lookup alias in this and if needed in parent
7992 2001-12-08 Miguel de Icaza <miguel@ximian.com>
7996 * rootcontext.cs: (ModuleBuilder) Made static, first step into
7997 making things static. I need this to avoid passing the
7998 TypeContainer when calling ParameterType.
8000 * support.cs (InternalParameters.ParameterType): Remove ugly hack
8001 that did string manipulation to compute the type and then call
8002 GetType. Use Parameter.ParameterType instead.
8004 * cs-tokenizer.cs: Consume the suffix for floating values.
8006 * expression.cs (ParameterReference): figure out whether this is a
8007 reference parameter or not. Kill an extra variable by computing
8008 the arg_idx during emission.
8010 * parameter.cs (Parameters.GetParameterInfo): New overloaded
8011 function that returns whether a parameter is an out/ref value or not.
8013 (Parameter.ParameterType): The type of the parameter (base,
8014 without ref/out applied).
8016 (Parameter.Resolve): Perform resolution here.
8017 (Parameter.ExternalType): The full type (with ref/out applied).
8019 * statement.cs (Using.Emit, Using.EmitExpression): Implement
8020 support for expressions on the using statement.
8022 2001-12-07 Miguel de Icaza <miguel@ximian.com>
8024 * statement.cs (Using.EmitLocalVariableDecls): Split the
8025 localvariable handling of the using statement.
8027 (Block.EmitMeta): Keep track of variable count across blocks. We
8028 were reusing slots on separate branches of blocks.
8030 (Try.Emit): Emit the general code block, we were not emitting it.
8032 Check the type of the declaration to be an IDisposable or
8033 something that can be implicity converted to it.
8035 Emit conversions if required.
8037 * ecore.cs (EmptyExpression): New utility class.
8038 (Expression.ImplicitConversionExists): New utility function.
8040 2001-12-06 Miguel de Icaza <miguel@ximian.com>
8042 * statement.cs (Using): Implement.
8044 * expression.cs (LocalVariableReference): Support read only variables.
8046 * statement.cs: Remove the explicit emit for the Leave opcode.
8047 (VariableInfo): Add a readonly field.
8049 2001-12-05 Miguel de Icaza <miguel@ximian.com>
8051 * ecore.cs (ConvCast): new class used to encapsulate the various
8052 explicit integer conversions that works in both checked and
8055 (Expression.ConvertNumericExplicit): Use new ConvCast class to
8056 properly generate the overflow opcodes.
8058 2001-12-04 Miguel de Icaza <miguel@ximian.com>
8060 * statement.cs: The correct type for the EmptyExpression is the
8061 element_type, not the variable type. Ravi pointed this out.
8063 2001-12-04 Ravi Pratap <ravi@ximian.com>
8065 * class.cs (Method::Define): Handle PInvoke methods specially
8066 by using DefinePInvokeMethod instead of the usual one.
8068 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
8069 above to do the task of extracting information and defining the method.
8071 2001-12-04 Ravi Pratap <ravi@ximian.com>
8073 * expression.cs (ArrayCreation::EmitStaticInitializers): Get rid
8074 of the condition for string type.
8076 (Emit): Move that here.
8078 (ArrayCreation::CheckIndices): Keep string literals in their expression
8081 (EmitDynamicInitializers): Handle strings appropriately.
8083 2001-12-04 Miguel de Icaza <miguel@ximian.com>
8085 * codegen.cs (EmitContext): Replace multiple variables with a
8086 single pointer to the current Switch statement.
8088 * statement.cs (GotoDefault, Switch): Adjust to cleaned up
8091 2001-12-03 Miguel de Icaza <miguel@ximian.com>
8095 * statement.cs (GotoDefault), cs-parser.jay: Implement `goto
8098 (Foreach.Emit): Foreach on arrays was not setting
8099 up the loop variables (for break/continue).
8101 (GotoCase): Semi-implented.
8103 2001-12-03 Ravi Pratap <ravi@ximian.com>
8105 * attribute.cs (CheckAttribute): Handle system attributes by using
8106 Attribute.GetAttributes to examine information we need.
8108 (GetValidPlaces): Same here.
8110 * class.cs (Method::Define): Catch invalid use of extern and abstract together.
8112 * typemanager.cs (dllimport_type): Core type for System.DllImportAttribute.
8114 * class.cs (Method.IsPinvoke): Used to determine if we are a PInvoke method.
8116 (Method::Define): Set appropriate flags if we have a DllImport attribute.
8118 (Method::Emit): Handle the case when we are a PInvoke method.
8120 2001-12-03 Miguel de Icaza <miguel@ximian.com>
8122 * expression.cs: Use ResolveWithSimpleName on compound names.
8124 2001-12-02 Ravi Pratap <ravi@ximian.com>
8126 * constant.cs (EmitConstant): Make sure we resolve the associated expression
8127 before trying to reduce it.
8129 * typemanager.cs (RegisterConstant, LookupConstant): Implement.
8131 * constant.cs (LookupConstantValue): Implement.
8133 (EmitConstant): Use the above in emitting the constant.
8135 * expression.cs (MemberAccess::ResolveMemberAccess): Handle constants
8136 that are user-defined by doing a LookupConstantValue on them.
8138 (SimpleName::DoResolve): When we have a FieldExpr, cope with constants

8315 2001-11-22 Miguel de Icaza <miguel@ximian.com>
8317 * statement.cs (If.Emit): Fix a bug that generated incorrect code
8318 on If. Basically, we have to return `true' (ie, we do return to
8319 our caller) only if both branches of the if return.

8325 (Cast.Cast): Take an expression as the target type.
8327 * cs-parser.jay (cast_expression): Remove old hack that only
8328 allowed a limited set of types to be handled. Now we take a
8329 unary_expression and we resolve to a type during semantic
8332 Use the grammar productions from Rhys to handle casts (this is
8333 not complete like Rhys syntax yet, we fail to handle that corner
8334 case that C# has regarding (-x), but we will get there.
8336 2001-11-22 Ravi Pratap <ravi@ximian.com>
8338 * class.cs (EmitFieldInitializer): Take care of the case when we have a
8339 field which is an array type.

8347 * cs-parser.jay (for_statement): Update for array initialization while
8348 declaring variables.
8350 * ecore.cs : The error message was correct, it's the variable's names that
8351 were misleading ;-) Make the code more readable.
8353 (MemberAccess::DoResolve): Fix the code which handles Enum literals to set
8354 the correct type etc.
8356 (ConvertExplicit): Handle Enum types by examining the underlying type.

8371 BindingFlags.Instance as well
8373 * ecore.cs (Expression.TryImplicitIntConversion): Wrap the result
8374 implicit int literal conversion in an empty cast so that we
8375 propagate the right type upstream.

8378 (Expression.ConvertExplicit): Add explicit type conversions done
8381 (Expression.ImplicitNumericConversion): Oops, forgot to test for
8382 the target type before applying the implicit LongLiterals to ULong
8385 2001-11-21 Miguel de Icaza <miguel@ximian.com>
8387 * cs-parser.jay (for_statement): Reworked the way For works: now
8388 we declare manually any variables that are introduced in
8389 for_initializer to solve the problem of having out-of-band code
8390 emition (that is what got for broken).
8392 (declaration_statement): Perform the actual variable declaration
8393 that used to be done in local_variable_declaration here.
8395 (local_variable_declaration): Do not declare anything, just pass
8396 the information on a DictionaryEntry
8398 2001-11-20 Ravi Pratap <ravi@ximian.com>

8468 * cs-parser.jay: Use an out-of-band stack to pass information
8469 around, I wonder why I need this.

8473 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
8474 function used to return a static Parameters structure. Used for
8475 empty parameters, as those are created very frequently.

8479 2001-11-15 Ravi Pratap <ravi@ximian.com>
8481 * interface.cs : Default modifier is private, not public. The
8482 make verify test passes again.
8484 2001-11-15 Ravi Pratap <ravi@ximian.com>
8486 * support.cs (ReflectionParameters): Fix logic to determine
8487 whether the last parameter is a params one. Test 9 passes again.
8489 * delegate.cs (Populate): Register the builders we define with

8493 of $$ to get at the location.
8495 (indexer_declaration): Similar stuff.
8499 * class.cs (Property): Register parameters for the Get and Set methods
8500 if they exist. Test 23 passes again.

8507 IndexOutOfRangeException.
8509 * class.cs (Property::Define): Register property using TypeManager.RegisterProperty

8514 * cs-parser.jay: Kill horrendous hack ($??? = lexer.Location) that
8515 broke a bunch of things. Will have to come up with a better way
8516 of tracking locations.

8520 2001-11-09 Miguel de Icaza <miguel@ximian.com>

8546 location where this argument is used. Notice that this is not
8547 part of the "Argument" class as to reduce the size of the
8548 structure (we know the approximate location anyways).

8551 complain with a 206.
8553 (Argument.Emit): Emit addresses of variables.
8555 (Argument.FullDesc): Simplify.

8584 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
8585 enumerations that are used in heavily used structures derive from
8586 byte in a laughable and pathetic attempt to reduce memory usage.

8588 home without adult supervision.
8590 * expression.cs (UnaryMutator): New class, used to handle ++ and
8591 -- separatedly from the other unary operators. Cleans up the
8592 code, and kills the ExpressionStatement dependency in Unary.
8594 (Unary): Removed `method' and `Arguments' from this class, making
8595 it smaller, and moving it all to SimpleCall, so I can reuse this
8596 code in other locations and avoid creating a lot of transient data
8597 strucutres when not required.
8599 * cs-parser.jay: Adjust for new changes.
8601 2001-11-11 Miguel de Icaza <miguel@ximian.com>
8603 * enum.cs (Enum.Populate): If there is a failure during

8672 of a fieldinfo using the above, when dealing with a FieldBuilder.

8719 2001-11-09 Miguel de Icaza <miguel@ximian.com>
8721 * cs-parser.jay: A for_initializer if is a
8722 local_variable_declaration really ammount to have an implicit
8723 block with the variable declaration and no initializer for for.

8758 Emit method everywhere.
8760 * enum.cs (Enum): Revamp to use the same definition semantics as delegates so

8835 IStackStore as the order in which arguments are passed reflects
8838 * assign.cs: Instead of using expr.ExprClass to select the way of
8839 assinging, probe for the IStackStore/IAssignMethod interfaces.
8841 * typemanager.cs: Load InitializeArray definition.
8843 * rootcontext.cs (RootContext.MakeStaticData): Used to define
8844 static data that can be used to initialize arrays.

9526 type to EmitContext.
9528 2001-10-09 Miguel de Icaza <miguel@ximian.com>

9540 * codegen.cs: EmitContext now contains a flag indicating whether
9541 code is being generated in a static method or not.
9543 * cs-parser.jay: DecomposeQI, new function that replaces the old
9544 QualifiedIdentifier. Now we always decompose the assembled
9545 strings from qualified_identifier productions into a group of
9548 2001-10-08 Miguel de Icaza <miguel@ximian.com>
9550 * rootcontext.cs: Deal with field-less struct types correctly now

9557 * statement.cs: Moved most of the code generation here.
9559 2001-10-09 Ravi Pratap <ravi@ximian.com>
9561 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
9564 (ElementAccess): Remove useless bits for now - keep checks as the spec
9567 2001-10-08 Ravi Pratap <ravi@ximian.com>
9569 * expression.cs (ElementAccess::DoResolve): Remove my crap code
9570 and start performing checks according to the spec.
9572 2001-10-07 Ravi Pratap <ravi@ximian.com>
9574 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
9575 rank_specifiers instead.
9577 (rank_specifiers): Change the order in which the rank specifiers are stored
9579 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
9581 * expression.cs (ElementAccess): Implement the LValue interface too.
9583 2001-10-06 Ravi Pratap <ravi@ximian.com>
9585 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
9586 except that user defined conversions are not included.
9588 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
9589 perform the conversion of the return type, if necessary.
9591 (New::DoResolve): Check whether we are creating an array or an object
9592 and accordingly do the needful.
9594 (New::Emit): Same here.
9596 (New::DoResolve): Implement guts of array creation.
9598 (New::FormLookupType): Helper function.
9600 2001-10-07 Miguel de Icaza <miguel@ximian.com>

9607 * cs-parser.jay: Added support for try/catch/finalize.
9609 * class.cs: Catch static methods having the flags override,
9610 virtual or abstract.
9612 * expression.cs (UserCast): This user cast was not really doing
9613 what it was supposed to do. Which is to be born in fully resolved
9614 state. Parts of the resolution were being performed at Emit time!
9618 2001-10-05 Miguel de Icaza <miguel@ximian.com>
9620 * expression.cs: Implicity convert the result from UserCast.
9622 2001-10-05 Ravi Pratap <ravi@ximian.com>
9624 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
9625 prevented it from working correctly.

9628 merely ConvertImplicit.
9630 2001-10-05 Miguel de Icaza <miguel@ximian.com>
9632 * typemanager.cs: Make the LookupTypeContainer function static,
9633 and not per-instance.
9635 * class.cs: Make static FindMembers (the one that takes a Type
9638 * codegen.cs: Add EmitForeach here.
9640 * cs-parser.jay: Make foreach a toplevel object instead of the
9641 inline expansion, as we need to perform semantic analysis on it.
9643 2001-10-05 Ravi Pratap <ravi@ximian.com>
9645 * expression.cs (Expression::ImplicitUserConversion): Rename to
9646 UserDefinedConversion.
9648 (Expression::UserDefinedConversion): Take an extra argument specifying
9649 whether we look for explicit user conversions too.
9651 (Expression::ImplicitUserConversion): Make it a call to UserDefinedConversion.

9660 * expression.cs (Cast): Record location info.
9662 (Expression::ConvertExplicit): Take location argument.
9664 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
9665 to determine if we are doing explicit conversions.
9667 (UserCast::Emit): Update accordingly.
9669 (Expression::ConvertExplicit): Report an error if everything fails.
9671 * ../errors/cs0030.cs : Add.
9673 2001-10-04 Miguel de Icaza <miguel@ximian.com>
9675 * modifiers.cs: If the ABSTRACT keyword is present, also set the
9676 virtual and newslot bits.
9678 * class.cs (TypeContainer::RegisterRequiredImplementations):
9679 Record methods we need.
9681 (TypeContainer::MakeKey): Helper function to make keys for
9682 MethodBases, since the Methodbase key is useless.
9684 (TypeContainer::Populate): Call RegisterRequiredImplementations
9685 before defining the methods.
9687 Create a mapping for method_builders_to_methods ahead of time
9688 instead of inside a tight loop.
9690 (::RequireMethods): Accept an object as the data to set into the
9691 hashtable so we can report interface vs abstract method mismatch.
9693 2001-10-03 Miguel de Icaza <miguel@ximian.com>
9695 * report.cs: Make all of it static.
9697 * rootcontext.cs: Drop object_type and value_type computations, as
9698 we have those in the TypeManager anyways.
9700 Drop report instance variable too, now it is a global.
9702 * driver.cs: Use try/catch on command line handling.
9704 Add --probe option to debug the error reporting system with a test
9707 * report.cs: Add support for exiting program when a probe
9708 condition is reached.
9710 2001-10-03 Ravi Pratap <ravi@ximian.com>
9712 * expression.cs (Binary::DoNumericPromotions): Fix the case when
9713 we do a forcible conversion regardless of type, to check if
9714 ForceConversion returns a null.
9716 (Binary::error19): Use location to report error.
9718 (Unary::error23): Use location here too.
9720 * ../errors/cs0019.cs : Check in.
9722 * ../errors/cs0023.cs : Check in.
9724 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
9725 case of a non-null MethodInfo object with a length of 0 !
9727 (Binary::ResolveOperator): Flag error if overload resolution fails to find
9728 an applicable member - according to the spec :-)
9729 Also fix logic to find members in base types.
9731 (Unary::ResolveOperator): Same here.
9733 (Unary::report23): Change name to error23 and make first argument a TypeContainer
9734 as I was getting thoroughly confused between this and error19 :-)
9736 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
9737 (::FindMostEncompassedType): Implement.
9738 (::FindMostEncompassingType): Implement.
9739 (::StandardConversionExists): Implement.
9741 (UserImplicitCast): Re-vamp. We now need info about most specific
9742 source and target types so that we can do the necessary conversions.
9744 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
9745 mathematical union with no duplicates.
9747 2001-10-03 Miguel de Icaza <miguel@ximian.com>
9749 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
9750 in order from base classes to child classes, so that we can in
9751 child classes look up in our parent for method names and
9752 attributes (required for handling abstract, virtual, new, override
9753 constructs: we need to instrospect our base class, and if we dont
9754 populate the classes in order, the introspection might be
9755 incorrect. For example, a method could query its parent before
9756 the parent has any methods and would determine that the parent has
9757 no abstract methods (while it could have had them)).
9759 (RootContext::CreateType): Record the order in which we define the
9762 2001-10-02 Miguel de Icaza <miguel@ximian.com>
9764 * class.cs (TypeContainer::Populate): Also method definitions can
9765 fail now, keep track of this.
9767 (TypeContainer::FindMembers): Implement support for
9768 DeclaredOnly/noDeclaredOnly flag.
9770 (Constructor::Emit) Return the ConstructorBuilder.
9772 (Method::Emit) Return the MethodBuilder.
9773 Check for abstract or virtual methods to be public.
9775 * rootcontext.cs (RootContext::CreateType): Register all the
9776 abstract methods required for the class to be complete and the
9777 interface methods that must be implemented.
9779 * cs-parser.jay: Report error 501 (method requires body if it is
9780 not marked abstract or extern).
9782 * expression.cs (TypeOf::Emit): Implement.
9784 * typemanager.cs: runtime_handle_type, new global type.
9786 * class.cs (Property::Emit): Generate code for properties.
9788 2001-10-02 Ravi Pratap <ravi@ximian.com>
9790 * expression.cs (Unary::ResolveOperator): Find operators on base type
9791 too - we now conform exactly to the spec.
9793 (Binary::ResolveOperator): Same here.
9795 * class.cs (Operator::Define): Fix minor quirk in the tests.
9797 * ../errors/cs0215.cs : Added.
9799 * ../errors/cs0556.cs : Added.
9801 * ../errors/cs0555.cs : Added.
9803 2001-10-01 Miguel de Icaza <miguel@ximian.com>
9805 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
9806 single integer which is really efficient
9808 2001-10-01 Ravi Pratap <ravi@ximian.com>
9810 * expression.cs (Expression::ImplicitUserConversion): Use location
9811 even in the case when we are examining True operators.
9813 * class.cs (Operator::Define): Perform extensive checks to conform
9814 with the rules for operator overloading in the spec.
9816 * expression.cs (Expression::ImplicitReferenceConversion): Implement
9817 some of the other conversions mentioned in the spec.
9819 * typemanager.cs (array_type): New static member for the System.Array built-in
9822 (cloneable_interface): For System.ICloneable interface.
9824 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
9825 we start resolving the tree and populating types.
9827 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
9829 2001-10-01 Miguel de Icaza <miguel@ximian.com>
9831 * expression.cs (Expression::ExprClassFromMemberInfo,
9832 Expression::Literalize): Create literal expressions from
9833 FieldInfos which are literals.
9835 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
9836 type casts, because they were wrong. The test suite in tests
9839 (ImplicitNumericConversion): ushort to ulong requires a widening
9842 Int32 constant to long requires widening cast as well.
9844 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
9845 for integers because the type on the stack is not i4.
9847 2001-09-30 Miguel de Icaza <miguel@ximian.com>
9849 * expression.cs (report118): require location argument.
9851 * parameter.cs: Do not dereference potential null value.
9853 * class.cs: Catch methods that lack the `new' keyword when
9854 overriding a name. Report warnings when `new' is used without
9855 anything being there to override.
9857 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
9859 * class.cs: Only add constructor to hashtable if it is non-null
9860 (as now constructors can fail on define).
9862 (TypeManager, Class, Struct): Take location arguments.
9864 Catch field instance initialization in structs as errors.
9866 accepting_filter: a new filter for FindMembers that is static so
9867 that we dont create an instance per invocation.
9869 (Constructor::Define): Catch errors where a struct constructor is
9872 * cs-parser.jay: Pass location information for various new
9875 * delegate.cs (Delegate): take a location argument.
9877 * driver.cs: Do not call EmitCode if there were problesm in the
9878 Definition of the types, as many Builders wont be there.
9880 * decl.cs (Decl::Decl): Require a location argument.
9882 * cs-tokenizer.cs: Handle properly hex constants that can not fit
9883 into integers, and find the most appropiate integer for it.
9885 * literal.cs: Implement ULongLiteral.
9887 * rootcontext.cs: Provide better information about the location of
9888 failure when CreateType fails.
9890 2001-09-29 Miguel de Icaza <miguel@ximian.com>
9892 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
9895 * expression.cs (Binary::CheckShiftArguments): Add missing type
9897 (Binary::ResolveOperator): Add type to the logical and and logical
9898 or, Bitwise And/Or and Exclusive Or code paths, it was missing
9901 (Binary::DoNumericPromotions): In the case where either argument
9902 is ulong (and most signed types combined with ulong cause an
9903 error) perform implicit integer constant conversions as well.
9905 2001-09-28 Miguel de Icaza <miguel@ximian.com>
9907 * expression.cs (UserImplicitCast): Method should always be
9909 (Invocation::BetterConversion): Simplified test for IntLiteral.
9911 (Expression::ImplicitNumericConversion): Split this routine out.
9912 Put the code that performs implicit constant integer conversions
9915 (Expression::Resolve): Become a wrapper around DoResolve so we can
9916 check eclass and type being set after resolve.
9918 (Invocation::Badness): Remove this dead function
9920 (Binary::ResolveOperator): Do not compute the expensive argumnets
9921 unless we have a union for it.
9923 (Probe::Emit): Is needs to do an isinst and then
9924 compare against null.
9926 (::CanConvert): Added Location argument. If the Location argument
9927 is null (Location.Null), then we do not report errors. This is
9928 used by the `probe' mechanism of the Explicit conversion. We do
9929 not want to generate an error for something that the user
9930 explicitly requested to be casted. But the pipeline for an
9931 explicit cast first tests for potential implicit casts.
9933 So for now, if the Location is null, it means `Probe only' to
9934 avoid adding another argument. Might have to revise this
9937 (ClassCast): New class used to type cast objects into arbitrary
9938 classes (used in Explicit Reference Conversions).
9940 Implement `as' as well.
9942 Reverted all the patches from Ravi below: they were broken:
9944 * The use of `level' as a mechanism to stop recursive
9945 invocations is wrong. That was there just to catch the
9946 bug with a strack trace but not as a way of addressing
9949 To fix the problem we have to *understand* what is going
9950 on and the interactions and come up with a plan, not
9951 just get things going.
9953 * The use of the type conversion cache that I proposed
9954 last night had an open topic: How does this work across
9955 protection domains. A user defined conversion might not
9956 be public in the location where we are applying the
9957 conversion, a different conversion might be selected
9958 (ie, private A->B (better) but public B->A (worse),
9959 inside A, A->B applies, but outside it, B->A will
9962 * On top of that (ie, even if the above is solved),
9963 conversions in a cache need to be abstract. Ie, `To
9964 convert from an Int to a Short use an OpcodeCast', not
9965 `To convert from an Int to a Short use the OpcodeCast on
9966 the variable 5' (which is what this patch was doing).
9968 2001-09-28 Ravi Pratap <ravi@ximian.com>
9970 * expression.cs (Invocation::ConversionExists): Re-write to use
9971 the conversion cache
9973 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
9974 cache all conversions done, not just user-defined ones.
9976 (Invocation::BetterConversion): The real culprit. Use ConversionExists
9977 to determine if a conversion exists instead of acutually trying to
9978 perform the conversion. It's faster too.
9980 (Expression::ConvertExplicit): Modify to use ConversionExists to check
9981 and only then attempt the implicit conversion.
9983 2001-09-28 Ravi Pratap <ravi@ximian.com>
9985 * expression.cs (ConvertImplicit): Use a cache for conversions
9986 already found. Check level of recursion and bail out if necessary.
9988 2001-09-28 Miguel de Icaza <miguel@ximian.com>
9990 * typemanager.cs (string_concat_string_string, string_concat_object_object):
9991 Export standard methods that we expect for string operations.
9993 * statement.cs (Block::UsageWarning): Track usage of variables and
9994 report the errors for not used variables.
9996 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
9999 2001-09-27 Miguel de Icaza <miguel@ximian.com>
10001 * codegen.cs: remove unnneded code
10003 * expression.cs: Removed BuiltinTypeAccess class
10005 Fix the order in which implicit conversions are
10008 The previous fixed dropped support for boxed conversions (adding a
10009 test to the test suite now)
10011 (UserImplicitCast::CanConvert): Remove test for source being null,
10012 that code is broken. We should not feed a null to begin with, if
10013 we do, then we should track the bug where the problem originates
10014 and not try to cover it up here.
10016 Return a resolved expression of type UserImplicitCast on success
10017 rather than true/false. Ravi: this is what I was talking about,
10018 the pattern is to use a static method as a "constructor" for
10021 Also, do not create arguments until the very last minute,
10022 otherwise we always create the arguments even for lookups that
10023 will never be performed.
10025 (UserImplicitCast::Resolve): Eliminate, objects of type
10026 UserImplicitCast are born in a fully resolved state.
10028 * typemanager.cs (InitCoreTypes): Init also value_type
10029 (System.ValueType).
10031 * expression.cs (Cast::Resolve): First resolve the child expression.
10033 (LValue): Add new method AddressOf to be used by
10036 Change the argument of Store to take an EmitContext instead of an
10037 ILGenerator, because things like FieldExpr need to be able to call
10038 their children expression to generate the instance code.
10040 (Expression::Error, Expression::Warning): Sugar functions for
10043 (Expression::MemberLookup): Accept a TypeContainer instead of a
10044 Report as the first argument.
10046 (Expression::ResolvePrimary): Killed. I still want to improve
10047 this as currently the code is just not right.
10049 (Expression::ResolveMemberAccess): Simplify, but it is still
10052 (Unary::Resolve): Catch errors in AddressOf operators.
10054 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
10055 index to a byte for the short-version, or the compiler will choose
10056 the wrong Emit call, which generates the wrong data.
10058 (ParameterReference::Emit, ::Store): same.
10060 (FieldExpr::AddressOf): Implement.
10062 * typemanager.cs: TypeManager: made public variable instead of
10065 * driver.cs: document --fatal.
10067 * report.cs (ErrorMessage, WarningMessage): new names for the old
10068 Error and Warning classes.
10070 * cs-parser.jay (member_access): Turn built-in access to types
10071 into a normal simplename
10073 2001-09-27 Ravi Pratap <ravi@ximian.com>
10075 * expression.cs (Invocation::BetterConversion): Fix to cope
10076 with q being null, since this was introducing a bug.
10078 * expression.cs (ConvertImplicit): Do built-in conversions first.
10080 2001-09-27 Ravi Pratap <ravi@ximian.com>
10082 * expression.cs (UserImplicitCast::Resolve): Fix bug.
10084 2001-09-27 Ravi Pratap <ravi@ximian.com>
10086 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
10087 I had introduced long ago (what's new ?).
10089 * expression.cs (UserImplicitCast::CanConvert): Static method to do
10090 the work of all the checking.
10091 (ConvertImplicit): Call CanConvert and only then create object if necessary.
10092 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
10094 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
10095 that is the right way.
10097 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
10098 overloading resolution. Use everywhere instead of cutting and pasting code.
10100 (Binary::ResolveOperator): Use MakeUnionSet.
10102 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
10103 we have to convert to bool types. Not complete yet.
10105 2001-09-27 Miguel de Icaza <miguel@ximian.com>
10107 * typemanager.cs (TypeManager::CSharpName): support ushort.
10109 * expression.cs (Expression::TryImplicitIntConversion): Attempts
10110 to provide an expression that performsn an implicit constant int
10111 conversion (section 6.1.6).
10112 (Expression::ConvertImplicitRequired): Reworked to include
10113 implicit constant expression conversions.
10115 (Expression::ConvertNumericExplicit): Finished.
10117 (Invocation::Emit): If InstanceExpression is null, then it means
10118 that we perform a call on this.
10120 2001-09-26 Miguel de Icaza <miguel@ximian.com>
10122 * expression.cs (Unary::Emit): Remove some dead code.
10123 (Probe): Implement Resolve and Emit for `is'.
10124 (Expression::ConvertImplicitRequired): Attempt to do constant
10125 expression conversions here. Maybe should be moved to
10126 ConvertImplicit, but I am not sure.
10127 (Expression::ImplicitLongConstantConversionPossible,
10128 Expression::ImplicitIntConstantConversionPossible): New functions
10129 that tell whether is it possible to apply an implicit constant
10130 expression conversion.
10132 (ConvertNumericExplicit): Started work on explicit numeric
10135 * cs-parser.jay: Update operator constants.
10137 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
10138 (Parameters::GetSignature): Hook up VerifyArgs here.
10139 (Parameters::VerifyArgs): Verifies that no two arguments have the
10142 * class.cs (Operator): Update the operator names to reflect the
10143 ones that the spec expects (as we are just stringizing the
10146 * expression.cs (Unary::ResolveOperator): Fix bug: Use
10147 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
10148 previous usage did only work for our methods.
10149 (Expression::ConvertImplicit): Handle decimal implicit numeric
10150 conversions as well.
10151 (Expression::InternalTypeConstructor): Used to invoke constructors
10152 on internal types for default promotions.
10154 (Unary::Emit): Implement special handling for the pre/post
10155 increment/decrement for overloaded operators, as they need to have
10156 the same semantics as the other operators.
10158 (Binary::ResolveOperator): ditto.
10159 (Invocation::ConversionExists): ditto.
10160 (UserImplicitCast::Resolve): ditto.
10162 2001-09-26 Ravi Pratap <ravi@ximian.com>
10164 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded
10165 operator, return after emitting body. Regression tests pass again !
10167 * expression.cs (ConvertImplicit): Take TypeContainer as first argument
10168 (Unary::ForceConversion, Binary::ForceConversion): Ditto.
10169 (Invocation::OverloadResolve): Ditto.
10170 (Invocation::BetterFunction, BetterConversion, ConversionExists): Ditto.
10172 * everywhere : update calls to the above methods accordingly.
10174 2001-09-26 Miguel de Icaza <miguel@ximian.com>
10176 * assign.cs (Assign): Make it inherit from ExpressionStatement.
10178 * expression.cs (ExpressionStatement): New base class used for
10179 expressions that can appear in statements, so that we can provide
10180 an alternate path to generate expression that do not leave a value
10183 (Expression::Emit, and all the derivatives): We no longer return
10184 whether a value is left on the stack or not. Every expression
10185 after being emitted leaves a single value on the stack.
10187 * codegen.cs (EmitContext::EmitStatementExpression): Use the
10188 facilties of ExpressionStatement if possible.
10190 * cs-parser.jay: Update statement_expression.
10192 2001-09-25 Miguel de Icaza <miguel@ximian.com>
10194 * driver.cs: Change the wording of message
10196 2001-09-25 Ravi Pratap <ravi@ximian.com>
10198 * expression.cs (Binary::ResolveOperator): Had forgottten to set
10199 the type of the expression to the return type of the method if
10200 we have an overloaded operator match ! The regression tests pass again !
10201 (Unary::ResolveOperator): Ditto.
10203 * expression.cs (Invocation::ConversionExists): Correct the member lookup
10204 to find "op_Implicit", not "implicit" ;-)
10205 (UserImplicitCast): New class to take care of user-defined implicit conversions.
10206 (ConvertImplicit, ForceConversion): Take TypeContainer argument
10208 * everywhere : Correct calls to the above accordingly.

10223 (Unary::ResolveOperator): Handle `Substract' for non-constants
10224 (substract from zero from the non-constants).

10281 * typemanager.cs: declare and load enum_type, delegate_type and
10284 * expression.cs (Expression::Emit): Now emit returns a value that
10285 tells whether a value is left on the stack or not. This strategy
10286 might be reveted tomorrow with a mechanism that would address
10287 multiple assignments.

10339 * expression.cs: Instead of having FIXMEs in the Resolve
10340 functions, throw exceptions so it is obvious that we are facing a

10345 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
10346 Use a basename for those routines because .NET does not like paths

10370 * expression.cs (Binary::Emit): Finally get the emission right ! Woo!
10372 * class.cs (Operator::Define): Change the methodname prefix to 'op_'
10373 instead of 'Operator'
10375 * expression.cs (Binary::ResolveOperator): Update accordingly.
10376 (Unary::Operator): Change names to 'Add' and 'Subtract' instead 'Plus'
10379 * cs-parser.jay (unary_expression): Update to use the new names.

10383 * expression.cs (Unary::Resolve): Implement.
10384 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
10385 operators are found instead of making noise ;-)
10386 (Unary::ResolveOperator): New method to do precisely the same thing which
10387 Binary::ResolveOperator does for Binary expressions.
10388 (Unary.method, .Arguments): Add.
10389 (Unary::OperName): Implement.
10390 (Unary::ForceConversion): Copy and Paste !
10392 * class.cs (Operator::Define): Fix a small bug for the case when we have
10395 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
10396 for the inbuilt operators. Only overloading works for now ;-)
10398 2001-09-18 Miguel de Icaza <miguel@ximian.com>

10411 represents the object instance.
10412 (FieldExpr::Resolve): Track potential errors from MemberLookup not
10414 (FieldExpr::Emit): Implement.
10416 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
10417 the last instruction contains a return opcode to avoid generating
10418 the last `ret' instruction (this generates correct code, and it is
10419 nice to pass the peverify output).
10421 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
10422 initializer for static and instance variables.
10423 (Constructor::Emit): Allow initializer to be null in the case of
10424 static constructors. Only emit initializer for instance
10427 (TypeContainer::FindMembers): Return a null array if there are no
10430 Also fix the code for the MemberTypes.Method branch, as it was not

10437 * driver.cs: Stop compilation if there are parse errors.
10439 * cs-parser.jay (constructor_declaration): Provide default base

10441 (constructor_declarator): Do not provide a default base
10442 initializers if none was specified.
10443 Catch the fact that constructors should not have parameters.
10445 * class.cs: Do not emit parent class initializers for static
10446 constructors, that should be flagged as an error.
10448 2001-09-18 Ravi Pratap <ravi@ximian.com>
10450 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
10451 Move back code into TypeContainer::Populate.
10453 2001-09-18 Ravi Pratap <ravi@ximian.com>
10455 * class.cs (TypeContainer::AddConstructor): Fix the check to

10469 (Operator::Emit): Re-write.
10471 * expression.cs (Binary::Emit): Comment out code path to emit method

10477 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
10480 (Expression::MemberLookup): Provide a version that allows to
10481 specify the MemberTypes and BindingFlags.
10483 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
10484 so it was not fetching variable information from outer blocks.
10486 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
10487 Beforefieldinit as it was buggy.
10489 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
10490 that Ravi put here.
10492 * class.cs (Constructor::Emit): Only emit if block is not null.
10493 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
10494 deal with this by semantically definining it as if the user had
10497 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
10498 constructors as we now "emit" them at a higher level.

10501 default constructors if none was provided.
10503 (ConstructorInitializer): Add methods Resolve and Emit.
10505 * expression.cs: Cast to ConstructorInfo instead of MethodInfo

10510 the default constructor builder with our hashtable for methodbuilders
10513 * expression.cs (Invocation::OverloadResolve): Add a check for pd == null

10527 * cs-parser.jay (operator_declaration, CheckBinaryOperator, CheckUnaryOperator): Update
10530 * expression.cs (Binary::method): New member to hold the MethodBase for the case when
10531 we have overloaded operators.
10532 (Binary::ResolveOperator): Implement the part which does the operator overload
10535 * class.cs (Operator::Emit): Implement.
10536 (TypeContainer::Emit): Emit the operators we have too.
10538 * expression.cs (Binary::Emit): Update to emit the appropriate code for
10539 the case when we have a user-defined operator.

10548 (TypeContainer::EmitConstructor): Remove and move code into Contructor::Emit.
10549 (Constructor::Emit): Implement.

10575 * class.cs (TypeContainer::FindMembers): Add support for
10577 (MethodCore): New class that encapsulates both the shared aspects
10578 of a Constructor and a Method.

10582 Load System assembly as well as part of the standard library.
10584 * report.cs: Allow throwing exceptions on errors for debugging.
10586 * modifiers.cs: Do not use `parent', instead use the real type
10587 container to evaluate permission settings.
10589 * class.cs: Put Ravi's patch back in. He is right, and we will
10590 have to cope with the
10592 2001-09-14 Ravi Pratap <ravi@ximian.com>
10594 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
10595 FamORAssem, not FamANDAssem.

10599 * driver.cs: Added --parse option that only parses its input files
10602 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
10603 incorrect. IsTopLevel is not used to tell whether an object is
10604 root_types or not (that can be achieved by testing this ==
10605 root_types). But to see if this is a top-level *class* (not
10606 necessarly our "toplevel" container).
10608 2001-09-14 Ravi Pratap <ravi@ximian.com>
10610 * enum.cs (Enum::Define): Modify to call the Lookup method on the
10611 parent instead of a direct call to GetType.

10615 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
10616 Modifiers.TypeAttr. This should just be a call to that method.
10618 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
10619 object so that we can determine if we are top-level or not.
10621 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
10624 * enum.cs (Enum::Define): Ditto.
10626 * modifiers.cs (FieldAttr): Re-write.
10628 * class.cs (TypeContainer::IsTopLevel): Change accessibility to public.
10629 (TypeContainer::HaveStaticConstructor): New property to provide access
10630 to precisely that info.
10632 * modifiers.cs (MethodAttr): Re-write.
10633 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
10635 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
10636 of top-level types as claimed.
10638 2001-09-13 Miguel de Icaza <miguel@ximian.com>
10640 * expression.cs (MemberLookup): Fruitless attempt to lookup
10641 constructors. Maybe I need to emit default constructors? That
10642 might be it (currently .NET emits this for me automatically).
10643 (Invocation::OverloadResolve): Cope with Arguments == null.
10644 (Invocation::EmitArguments): new function, shared by the new
10645 constructor and us.
10646 (Invocation::Emit): Handle static and instance methods. Emit

10658 SimpleLookup): Auxiliary routines to help parse a qualifier
10661 Update qualifier_identifier rule.
10663 * codegen.cs: Removed debugging messages.
10665 * class.cs: Make this a global thing, this acts just as a "key" to
10666 objects that we might have around.
10668 (Populate): Only initialize method_builders_to_methods once.
10670 * expression.cs (PropertyExpr): Initialize type from the
10673 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
10674 Resolve pattern. Attempt to implicitly convert value to boolean.
10677 * expression.cs: Set the type for the int32/int32 argument case.
10678 (Binary::ResolveOperator): Set the return type to boolean for
10679 comparission operators
10681 * typemanager.cs: Remove debugging print code.
10683 (Invocation::Resolve): resolve type.
10685 * class.cs: Allocate a MemberInfo of the correct size, as the code
10686 elsewhere depends on the test to reflect the correct contents.
10688 (Method::) Keep track of parameters, due to System.Reflection holes
10690 (TypeContainer::Populate): Keep track of MethodBuilders to Method
10693 (TypeContainer::FindMembers): Use ArrayList and then copy an array
10694 of the exact size and return that.
10696 (Class::LookupMethodByBuilder): New function that maps
10697 MethodBuilders to its methods. Required to locate the information
10698 on methods because System.Reflection bit us again.
10700 * support.cs: New file, contains an interface ParameterData and
10701 two implementations: ReflectionParameters and InternalParameters
10702 used to access Parameter information. We will need to grow this
10705 * expression.cs (Invocation::GetParameterData): implement a cache
10706 and a wrapper around the ParameterData creation for methods.
10707 (Invocation::OverloadResolve): Use new code.
10709 2001-09-13 Ravi Pratap <ravi@ximian.com>
10711 * class.cs (TypeContainer::EmitField): Remove and move into
10712 (Field::Define): here and modify accordingly.
10713 (Field.FieldBuilder): New member.
10714 (TypeContainer::Populate): Update accordingly.
10715 (TypeContainer::FindMembers): Implement.
10717 2001-09-13 Miguel de Icaza <miguel@ximian.com>

10730 (ParameterReference::Resolve): Implement.
10731 (ParameterReference::Emit): Implement.
10733 * cs-parser.jay: Fix bug introduced by Ravi, variable initializers

10751 types. Emits a box opcode.
10753 (Binary::DoNumericPromotions): Implements numeric promotions of
10754 and computation of the Binary::Type.
10756 (Binary::EmitBranchable): Optimization.
10758 (Binary::Emit): Implement code emission for expressions.
10760 * typemanager.cs (TypeManager): Added two new core types: sbyte
10763 2001-09-12 Ravi Pratap <ravi@ximian.com>
10765 * class.cs (TypeContainer::FindMembers): Method which does exactly
10766 what Type.FindMembers does, only we don't have to use reflection. No
10767 implementation yet.
10769 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
10770 typecontainer objects as we need to get at them.
10771 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.
10773 * rootcontext.cs : Correspondingly modify called to AddUserType to pass the
10774 typecontainer object.
10776 * expression.cs (MemberLookup): Modify signature to take a RootContext object instead

10793 * class.cs (Indexer::Define): Fix for loop iteration condition to be just <
10795 (Operator::Define): Re-write logic to get types by using the LookupType method
10796 instead of blindly doing a Type.GetType ! How stupid can I get ;-) ?
10797 (Indexer::Define): Ditto.
10798 (Event::Define): Ditto.
10799 (Property::Define): Ditto.
10801 2001-09-10 Ravi Pratap <ravi@ximian.com>

10813 addOn_ and removeOn_
10815 * genericparser.cs (GenericParser::error): Overloaded method to handle the case
10816 of the location being passed in too. Ideally, this should go later since all
10817 error reporting should be done through the Report object.
10819 * class.cs (TypeContainer.Indexers): New property to access the list of indexers.
10820 (Populate): Iterate thru the indexers we have and define them too.

10914 the parameter index.

11014 rename -t to --dumper.
11016 * expression.cs, literal.cs, assign.cs, constant.cs: All `Resolve'
11017 methods inherited from Expression return now an Expression. This
11018 will is used during the tree rewriting as we resolve them during

11136 (Event.EventBuilder): New member.
11138 * class.cs (TypeContainer::Populate): Update to define all enums and events

11143 2001-08-31 Ravi Pratap <ravi@che.iitm.ac.in>
11145 * class.cs (Property): Revamp to use the convention of making fields readonly.
11146 Accordingly modify code elsewhere.

11176 2001-08-29 Ravi Pratap <ravi@che.iitm.ac.in>
11178 * class.cs (Operator): New class for operator declarations.

11191 (catch_clauses): Modify accordingly.
11192 (opt_catch_clauses): New production to use in try_statement
11193 (try_statement): Revamp. Basically, we get rid of one unnecessary rule
11194 and re-write the code in the actions to extract the specific and
11195 general catch clauses by being a little smart ;-)
11197 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
11198 Hooray, try and catch statements parse fine !
11200 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
11202 * statement.cs (Block::GetVariableType): Fix logic to extract the type
11203 string from the hashtable of variables.
11205 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did
11206 I end up making that mistake ;-)
11207 (catch_clauses): Fixed gross error which made Key and Value of the
11208 DictionaryEntry the same : $1 !!

11221 (indexer_declarator): Implement actions.
11222 (parsing_indexer): New local boolean used to keep track of whether

11225 case of an indexer.
11226 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
11228 * class.cs (Indexer): New class for indexer declarations.

11250 concatenating all the commas together, just as they appear.
11251 (opt_dim_separators): Modify accordingly
11252 (rank_specifiers): Update accordingly. Basically do the same
11253 thing - instead, collect the brackets here.
11254 (opt_rank_sepcifiers): Modify accordingly.

11256 instead of ignoring the rank_specifiers.
11257 (expression_list): Implement to collect the expressions

11261 (array_initializer): Make it a list of variable_initializers
11262 (opt_array_initializer): Modify accordingly.

11268 members to hold data about array creation.

11283 * typemanager.cs (InitCoreTypes): Initialize the various core
11284 types after we have populated the type manager with the user
11285 defined types (this distinction will be important later while
11286 compiling corlib.dll)
11288 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
11289 on Expression Classification. Now all expressions have a method
11290 `Resolve' and a method `Emit'.
11292 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
11293 generation from working. Also add some temporary debugging
11296 2001-08-24 Miguel de Icaza <miguel@ximian.com>
11298 * codegen.cs: Lots of code generation pieces. This is only the
11299 beginning, will continue tomorrow with more touches of polish. We
11300 handle the fundamentals of if, while, do, for, return. Others are
11301 trickier and I need to start working on invocations soon.
11303 * gen-treedump.cs: Bug fix, use s.Increment here instead of
11306 * codegen.cs (EmitContext): New struct, used during code
11307 emission to keep a context. Most of the code generation will be
11310 * cs-parser.jay: Add embedded blocks to the list of statements of
11311 this block. So code generation proceeds in a top down fashion.
11313 2001-08-23 Miguel de Icaza <miguel@ximian.com>

11330 move from Properties to public readonly fields.
11331 (Method::ParameterTypes): Returns the parameter types for the
11332 function, and implements a cache that will be useful later when I
11333 do error checking and the semantic analysis on the methods is
11335 (Constructor::GetCallingConvention): Renamed from CallingConvetion
11336 and made a method, optional argument tells whether this is a class
11337 or a structure to apply the `has-this' bit.
11338 (Method::GetCallingConvention): Implement, returns the calling
11340 (Method::Define): Defines the type, a second pass is performed
11341 later to populate the methods.

11362 (TypeContainer::AddConstructor): Keep track of default constructor
11363 and the default static constructor.
11365 (Constructor::) Another class that starts using `public readonly'
11366 instead of properties.
11368 (Constructor::IsDefault): Whether this is a default constructor.
11370 (Field::) use readonly public fields instead of properties also.
11372 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
11373 track of static constructors; If none is used, turn on
11374 BeforeFieldInit in the TypeAttributes.
11376 * cs-parser.jay (opt_argument_list): now the return can be null
11377 for the cases where there are no arguments.
11379 (constructor_declarator): If there is no implicit `base' or
11380 `this', then invoke the default parent constructor.
11382 * modifiers.cs (MethodAttr): New static function maps a set of
11383 modifiers flags into a MethodAttributes enum
11384 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
11385 MethodAttr, TypeAttr to represent the various mappings where the
11386 modifiers are used.
11387 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
11389 2001-08-19 Miguel de Icaza <miguel@ximian.com>

11402 (PopulateProperty): Implement property population. Woohoo! Got
11403 Methods and Properties going today.
11405 Removed all the properties for interfaces, and replaced them with
11406 `public readonly' fields.
11408 2001-08-16 Miguel de Icaza <miguel@ximian.com>
11410 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
11411 initialize their hashtables/arraylists only when they are needed
11412 instead of doing this always.
11414 * parameter.cs: Handle refs and out parameters.
11416 * cs-parser.jay: Use an ArrayList to construct the arguments
11417 instead of the ParameterCollection, and then cast that to a
11420 * parameter.cs: Drop the use of ParameterCollection and use
11421 instead arrays of Parameters.
11423 (GetParameterInfo): Use the Type, not the Name when resolving
11426 2001-08-13 Miguel de Icaza <miguel@ximian.com>
11428 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
11429 and instead use public readonly fields.
11431 * class.cs: Put back walking code for type containers.
11433 2001-08-11 Miguel de Icaza <miguel@ximian.com>
11435 * class.cs (MakeConstant): Code to define constants.
11437 * rootcontext.cs (LookupType): New function. Used to locate types
11440 2001-08-08 Miguel de Icaza <miguel@ximian.com>
11442 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
11443 this System.Reflection code is. Kudos to Microsoft
11445 * typemanager.cs: Implement a type cache and avoid loading all
11446 types at boot time. Wrap in LookupType the internals. This made
11447 the compiler so much faster. Wow. I rule!
11449 * driver.cs: Make sure we always load mscorlib first (for
11450 debugging purposes, nothing really important).
11452 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
11453 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
11455 * rootcontext.cs: Lookup types on their namespace; Lookup types
11456 on namespaces that have been imported using the `using' keyword.
11458 * class.cs (TypeContainer::TypeAttr): Virtualize.
11459 (Class::TypeAttr): Return attributes suitable for this bad boy.
11460 (Struct::TypeAttr): ditto.
11461 Handle nested classes.
11462 (TypeContainer::) Remove all the type visiting code, it is now
11463 replaced with the rootcontext.cs code
11465 * rootcontext.cs (GetClassBases): Added support for structs.
11467 2001-08-06 Miguel de Icaza <miguel@ximian.com>
11469 * interface.cs, statement.cs, class.cs, parameter.cs,
11470 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
11471 Drop use of TypeRefs, and use strings instead.
11473 2001-08-04 Miguel de Icaza <miguel@ximian.com>
11477 * class.cs (Struct::Struct): set the SEALED flags after
11478 checking the modifiers.
11479 (TypeContainer::TypeAttr): new property, returns the
11480 TypeAttributes for a class.
11482 * cs-parser.jay (type_list): Oops, list production was creating a
11483 new list of base types.
11485 * rootcontext.cs (StdLib): New property.
11486 (GetInterfaceTypeByName): returns an interface by type name, and
11487 encapsulates error handling here.
11488 (GetInterfaces): simplified.
11489 (ResolveTree): Encapsulated all the tree resolution here.
11490 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
11493 * driver.cs: Add support for --nostdlib, to avoid loading the
11494 default assemblies.
11495 (Main): Do not put tree resolution here.
11497 * rootcontext.cs: Beginning of the class resolution.
11499 2001-08-03 Miguel de Icaza <miguel@ximian.com>
11501 * rootcontext.cs: Provide better error reporting.
11503 * cs-parser.jay (interface_base): set our $$ to be interfaces.
11505 * rootcontext.cs (CreateInterface): Handle the case where there
11506 are no parent interfaces.
11508 (CloseTypes): Routine to flush types at the end.
11509 (CreateInterface): Track types.
11510 (GetInterfaces): Returns an array of Types from the list of
11511 defined interfaces.
11513 * typemanager.c (AddUserType): Mechanism to track user types (puts
11514 the type on the global type hash, and allows us to close it at the
11517 2001-08-02 Miguel de Icaza <miguel@ximian.com>
11519 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
11520 RecordInterface instead.
11522 * cs-parser.jay: Updated to reflect changes above.
11524 * decl.cs (Definition): Keep track of the TypeBuilder type that
11525 represents this type here. Not sure we will use it in the long
11526 run, but wont hurt for now.
11528 * driver.cs: Smaller changes to accomodate the new code.
11530 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
11533 * rootcontext.cs (CreateInterface): New method, used to create
11534 the System.TypeBuilder type for interfaces.
11535 (ResolveInterfaces): new entry point to resolve the interface
11537 (CodeGen): Property, used to keep track of the code generator.
11539 2001-07-26 Miguel de Icaza <miguel@ximian.com>
11541 * cs-parser.jay: Add a second production for delegate_declaration
11544 (enum_body): Put an opt_comma here instead of putting it on
11545 enum_body or enum_member_declarations so we can handle trailing
11546 commas on enumeration members. Gets rid of a shift/reduce.
11548 (type_list): Need a COMMA in the middle.
11550 (indexer_declaration): Tell tokenizer to recognize get/set
11552 * Remove old targets.
11554 * Re-add the parser target.
11556 2001-07-13 Simon Cozens <simon@simon-cozens.org>
11558 * cs-parser.jay: Add precendence rules for a number of operators
11559 ot reduce the number of shift/reduce conflicts in the grammar.
11561 2001-07-17 Miguel de Icaza <miguel@ximian.com>
11563 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
11566 Get rid of old crufty code.
11568 * rootcontext.cs: Use this to keep track of the parsed
11569 representation and the defined types available to the program.
11571 * gen-treedump.cs: adjust for new convention.
11573 * type.cs: Split out the type manager, and the assembly builder
11576 * typemanager.cs: the type manager will live here now.
11578 * cil-codegen.cs: And the code generator here.
11580 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
11582 * makefile: Fixed up for easy making.
11584 2001-07-13 Simon Cozens <simon@simon-cozens.org>
11586 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
11589 (unary_expression): Expand pre_increment_expression and
11590 post_decrement_expression to reduce a shift/reduce.
11592 2001-07-11 Simon Cozens
11594 * cs-tokenizer.cs: Hex numbers should begin with a 0.
11596 Improve allow_keyword_as_indent name.
11598 2001-06-19 Miguel de Icaza <miguel@ximian.com>
11600 * Adjustments for Beta2.
11602 2001-06-13 Miguel de Icaza <miguel@ximian.com>
11604 * decl.cs: Added `Define' abstract method.
11605 (InTransit): new property, used to catch recursive definitions.
11607 * interface.cs: Implement `Define'.
11609 * modifiers.cs: Map Modifiers.constants to
11610 System.Reflection.TypeAttribute flags.
11612 * class.cs: Keep track of types and user-defined types.
11613 (BuilderInit): New method for creating an assembly
11614 (ResolveType): New function to launch the resolution process, only
11615 used by interfaces for now.
11617 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
11618 that are inserted into the name space.
11620 2001-06-08 Miguel de Icaza <miguel@ximian.com>
11622 * ARGH. I have screwed up my tree so many times due to the use of
11623 rsync rather than using CVS. Going to fix this at once.
11625 * driver.cs: Objetify driver. Load assemblies, use assemblies to
11628 2001-06-07 Miguel de Icaza <miguel@ximian.com>
11630 * Experiment successful: Use System.Type rather that our own
11633 2001-05-25 Miguel de Icaza <miguel@ximian.com>
11635 * cs-parser.jay: Removed nsAliases from here.
11637 Use new namespaces, handle `using XXX;'
11639 * namespace.cs: Reimplemented namespace handling, use a recursive
11640 definition of the class. Now we can keep track of using clauses
11641 and catch invalid using clauses.
11643 2001-05-24 Miguel de Icaza <miguel@ximian.com>
11645 * gen-treedump.cs: Adapted for all the renaming.
11647 * expression.cs (Expression): this class now has a Type property
11648 which returns an expression Type.
11650 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
11651 `Type', as this has a different meaning now in the base
11653 2001-05-22 Miguel de Icaza <miguel@ximian.com>
11655 * interface.cs, class.cs: Removed from all the sources the
11656 references to signature computation, as we can not do method
11657 signature computation during the parsing time, as we are not
11658 trying to solve at that point distinguishing:
11662 void a (NS.Blah x) {}
11665 Which depending on the context might be valid or not, as we do not
11666 know if Blah is the same thing as NS.Blah at that point.
11668 * Redid everything so the code uses TypeRefs now instead of
11669 Types. TypeRefs are just temporary type placeholders, that need
11670 to be resolved. They initially have a pointer to a string and the
11671 current scope in which they are used. This is used later by the
11672 compiler to resolve the reference to an actual Type.
11674 * DeclSpace is no longer a CIR.Type, and neither are
11675 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
11676 are all DeclSpaces, but no Types.
11678 * type.cs (TypeRefManager): This implements the TypeRef manager,
11679 which keeps track of all the types that need to be resolved after
11680 the parsing has finished.
11682 2001-05-13 Miguel de Icaza <miguel@ximian.com>
11684 * ARGH. We are going to have to store `foreach' as a class rather
11685 than resolving it, as we need to verify error 1579 after name
11686 resolution. *OR* we could keep a flag that says `This request to
11687 IEnumerator comes from a foreach statement' which we can then use
11688 to generate the error.
11690 2001-05-10 Miguel de Icaza <miguel@ximian.com>
11692 * class.cs (TypeContainer.AddMethod): we now add methods to the
11693 MethodGroup instead of the method hashtable.
11695 * expression.cs: Add MethodGroup abstraction, which gets us one
11696 step closer to the specification in the way we handle method
11699 * cs-parser.jay (primary_expression): qualified_identifier now
11700 tried to match up an identifier to a local variable reference or
11701 to a parameter reference.
11703 current_local_parameters is now a parser global variable that
11704 points to the current parameters for the block, used during name
11707 (property_declaration): Now creates an implicit `value' argument to
11710 2001-05-09 Miguel de Icaza <miguel@ximian.com>
11712 * parameter.cs: Do not use `param' arguments as part of the
11713 signature, per the spec.
11715 2001-05-08 Miguel de Icaza <miguel@ximian.com>
11717 * decl.cs: Base class for classes, structs and interfaces. This
11718 is the "Declaration Space"
11720 * cs-parser.jay: Use CheckDef for checking declaration errors
11721 instead of having one on each function.
11723 * class.cs: Factor out some code for handling error handling in
11724 accordance to the "Declarations" section in the "Basic Concepts"
11725 chapter in the ECMA C# spec.
11727 * interface.cs: Make all interface member classes derive from
11728 InterfaceMemberBase.
11730 2001-05-07 Miguel de Icaza <miguel@ximian.com>
11732 * Many things: all interfaces are parsed and generated in
11733 gen-treedump. Support for member variables, constructors,
11734 destructors, properties, constants is there.
11736 Beginning of the IL backend, but very little done, just there for
11739 2001-04-29 Miguel de Icaza <miguel@ximian.com>
11741 * cs-parser.jay: Fix labeled statement.
11743 * cs-tokenizer.cs (escape): Escape " and ' always.
11744 ref_line, ref_name: keep track of the line/filename as instructed
11745 by #line by the compiler.
11748 2001-04-27 Miguel de Icaza <miguel@ximian.com>
11750 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
11751 to match the values in System.CodeDOM.
11753 Divid renamed to Divide.
11755 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
11757 (Statements.set): remove.
11759 * System.CodeDOM/CodeCatchClause.cs: always have a valid
11762 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
11763 falseStatements always have valid values.
11765 * cs-parser.jay: Use System.CodeDOM now.
