1 2003-03-28 Miguel de Icaza <miguel@ximian.com>
3 * expression.cs (Unary.ResolveOperator): In LogicalNot, do an
4 implicit conversion to boolean.
6 * statement.cs (Statement.ResolveBoolean): A boolean expression is
7 also one where the type implements `operator true'.
9 * ecore.cs (Expression.GetOperatorTrue): New helper routine to
10 get an expression that will invoke operator true based on an
13 (GetConversionOperators): Removed the hack that called op_True
16 (Expression.ResolveBoolean): Move this from Statement.
18 2003-03-17 Miguel de Icaza <miguel@ximian.com>
20 * ecore.cs (FieldExpr): do not allow initialization of initonly
21 fields on derived classes
23 2003-03-13 Martin Baulig <martin@ximian.com>
25 * statement.cs (Block.Emit): Call ig.BeginScope() and
26 ig.EndScope() when compiling with debugging info; call
27 LocalBuilder.SetLocalSymInfo _after_ opening the scope.
29 2003-03-08 Miguel de Icaza <miguel@ximian.com>
31 * expression.cs (Indexers): Do not construct immediately, allow
32 for new members to be appended as we go. Fixes 38143
34 2003-03-07 Gonzalo Paniagua Javier <gonzalo@ximian.com>
36 * expression.cs: save/restore context when resolving an unchecked
39 2003-03-05 Miguel de Icaza <miguel@ximian.com>
41 * cfold.cs: Catch division by zero in modulus operator during
44 2003-03-03 Miguel de Icaza <miguel@ximian.com>
46 * interface.cs (Interface.DefineMembers): Avoid defining members
49 2003-02-27 Miguel de Icaza <miguel@ximian.com>
51 * driver.cs: handle the +/- options for -noconfig
53 * statement.cs (Unckeched.Resolve): Also track the state of
54 unchecked in the Resolve phase.
56 2003-02-27 Martin Baulig <martin@ximian.com>
58 * ecore.cs (Expression.MemberLookup): Don't create a
59 MethodGroupExpr for something which is not a method. Fixes #38291.
61 2003-02-25 Miguel de Icaza <miguel@ximian.com>
63 * class.cs (MemberBase.CheckParameters): Also check that the type
64 is unmanaged if it is a pointer.
66 * expression.cs (SizeOf.Resolve): Add location information.
68 * statement.cs (Block.EmitMeta): Flag error (208) if a pointer to
69 a managed type is declared.
71 * expression.cs (Invocation.VerifyArgumentsCompat): Check for the
72 parameter modifiers as well. Fixes bug 38606
74 * class.cs: Very sad. Am backing out the speed up changes
75 introduced by the ArrayList -> Array in the TypeContainer, as they
76 were not actually that much faster, and introduced a bug (no error
77 reports on duplicated methods).
79 * assign.cs (CompoundAssign.DoLResolve): Resolve the original
80 source first, this will guarantee that we have a valid expression
81 before calling in lower levels functions that will require a
82 resolved object. Then use this original_source in the
83 target.ResolveLValue instead of the original source that was
86 Another change. Use target.Resolve instead of LValueResolve.
87 Although we are resolving for LValues, we will let the Assign code
88 take care of that (it will be called again from Resolve). This
89 basically allows code like this:
91 class X { X operator + (X x, object o) {} X this [int idx] { get; set; } }
92 class Y { void A (X x) { x [0] += o; }
94 The problem was that the indexer was trying to resolve for
95 set_Item (idx, object o) and never finding one. The real set_Item
96 was set_Item (idx, X). By delaying the process we get the right
101 2003-02-23 Martin Baulig <martin@ximian.com>
103 * statement.cs (Block.Emit): Override this and set ec.CurrentBlock
104 while calling DoEmit ().
106 * codegen.cs (EmitContext.Mark): Don't mark locations in other
107 source files; if you use the #line directive inside a method, the
108 compiler stops emitting line numbers for the debugger until it
109 reaches the end of the method or another #line directive which
110 restores the original file.
112 2003-02-23 Martin Baulig <martin@ximian.com>
114 * statement.cs (FlowBranching.UsageVector.MergeChildren): Fix bug #37708.
116 2003-02-23 Martin Baulig <martin@ximian.com>
118 * statement.cs (Block.AddChildVariableNames): We need to call this
119 recursively, not just for our immediate children.
121 2003-02-23 Martin Baulig <martin@ximian.com>
123 * class.cs (Event.Define): Always make the field private, like csc does.
125 * typemanager.cs (TypeManager.RealMemberLookup): Make events
126 actually work, fixes bug #37521.
128 2003-02-23 Miguel de Icaza <miguel@ximian.com>
130 * delegate.cs: When creating the various temporary "Parameters"
131 classes, make sure that we call the ComputeAndDefineParameterTypes
132 on those new parameters (just like we do with the formal ones), to
133 allow them to be resolved in the context of the DeclSpace.
135 This fixes the bug that Dick observed in Bugzilla #38530.
137 2003-02-22 Miguel de Icaza <miguel@ximian.com>
139 * expression.cs (ResolveMemberAccess): When resolving a constant,
140 do not attempt to pull a constant if the value was not able to
141 generate a valid constant.
143 * const.cs (LookupConstantValue): Do not report more errors than required.
145 2003-02-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
147 * expression.cs: fixes bug #38328.
149 2003-02-18 Miguel de Icaza <miguel@ximian.com>
151 * class.cs: Changed all the various members that can be part of a
152 class from being an ArrayList to be an Array of the right type.
153 During the DefineType type_list, interface_list, delegate_list and
154 enum_list are turned into types, interfaces, delegates and enums
157 And during the member population, indexer_list, event_list,
158 constant_list, field_list, instance_constructor_list, method_list,
159 operator_list and property_list are turned into their real arrays.
161 Although we could probably perform this operation earlier, for
162 good error reporting we need to keep the lists and remove the
163 lists for longer than required.
165 This optimization was triggered by Paolo profiling the compiler
166 speed on the output of `gen-sample-program.pl' perl script.
168 * decl.cs (DeclSpace.ResolveType): Set the ContainerType, so we do
169 not crash in methods like MemberLookupFailed that use this field.
171 This problem arises when the compiler fails to resolve a type
172 during interface type definition for example.
174 2003-02-18 Miguel de Icaza <miguel@ximian.com>
176 * expression.cs (Indexers.GetIndexersForType): Interfaces do not
177 inherit from System.Object, so we have to stop at null, not only
178 when reaching System.Object.
180 2003-02-17 Miguel de Icaza <miguel@ximian.com>
182 * expression.cs: (Indexers.GetIndexersForType): Martin's fix used
183 DeclaredOnly because the parent indexer might have had a different
184 name, but did not loop until the top of the hierarchy was reached.
186 The problem this one fixes is 35492: when a class implemented an
187 indexer from an interface, we were getting the interface method
188 (which was abstract) and we were flagging an error (can not invoke
191 This also keeps bug 33089 functioning, and test-148 functioning.
193 * typemanager.cs (IsSpecialMethod): The correct way of figuring
194 out if a method is special is to see if it is declared in a
195 property or event, or whether it is one of the predefined operator
196 names. This should fix correctly #36804.
198 2003-02-15 Miguel de Icaza <miguel@ximian.com>
200 The goal here is to remove the dependency on EmptyCast.Peel ().
201 Killing it completely.
203 The problem is that currently in a number of places where
204 constants are expected, we have to "probe" for an EmptyCast, and
205 Peel, which is not the correct thing to do, as this will be
206 repetitive and will likely lead to errors.
208 The idea is to remove any EmptyCasts that are used in casts that
209 can be reduced to constants, so we only have to cope with
212 This bug hunt was triggered by Bug 37363 and the desire to remove
213 the duplicate pattern where we were "peeling" emptycasts to check
214 whether they were constants. Now constants will always be
217 * ecore.cs: Use an enumconstant here instead of wrapping with
220 * expression.cs (Cast.TryReduce): Ah, the tricky EnumConstant was
221 throwing me off. By handling this we can get rid of a few hacks.
223 * statement.cs (Switch): Removed Peel() code.
225 2003-02-14 Miguel de Icaza <miguel@ximian.com>
227 * class.cs: Location information for error 508
229 * expression.cs (New.DoResolve): Add a guard against double
230 resolution of an expression.
232 The New DoResolve might be called twice when initializing field
233 expressions (see EmitFieldInitializers, the call to
234 GetInitializerExpression will perform a resolve on the expression,
235 and later the assign will trigger another resolution
237 This leads to bugs (#37014)
239 * delegate.cs: The signature for EndInvoke should contain any ref
240 or out parameters as well. We were not doing this in the past.
242 * class.cs (Field.Define): Do not overwrite the type definition
243 inside the `volatile' group. Turns out that volatile enumerations
244 were changing the type here to perform a validity test, which
247 2003-02-12 Miguel de Icaza <miguel@ximian.com>
249 * ecore.cs (FieldExpr.AddressOf): In the particular case of This
250 and structs, we do not want to load the instance variable
252 (ImplicitReferenceConversion, ImplicitReferenceConversionExists):
253 enum_type has to be handled like an object reference (implicit
254 conversions exists from this to object), but the regular IsClass
255 and IsValueType tests will never return true for this one.
257 Also we use TypeManager.IsValueType instead of type.IsValueType,
258 just for consistency with the rest of the code (this is only
259 needed if we ever use the construct exposed by test-180.cs inside
260 corlib, which we dont today).
262 2003-02-12 Zoltan Varga <vargaz@freemail.hu>
264 * attribute.cs (ApplyAttributes): apply all MethodImplAttributes, not
267 2003-02-09 Martin Baulig <martin@ximian.com>
269 * namespace.cs (Namespace..ctor): Added SourceFile argument.
270 (Namespace.DefineNamespaces): New static public method; this is
271 called when we're compiling with debugging to add all namespaces
274 * tree.cs (Tree.RecordNamespace): Added SourceFile argument and
275 pass it to the Namespace's .ctor.
277 * symbolwriter.cs (SymbolWriter.OpenMethod): Added TypeContainer
278 and MethodBase arguments; pass the namespace ID to the symwriter;
279 pass the MethodBase instead of the token to the symwriter.
280 (SymbolWriter.DefineNamespace): New method to add a namespace to
283 2003-02-09 Martin Baulig <martin@ximian.com>
285 * symbolwriter.cs: New file. This is a wrapper around
286 ISymbolWriter with a cleaner API. We'll dynamically Invoke()
287 methods here in near future.
289 2003-02-09 Martin Baulig <martin@ximian.com>
291 * codegen.cs (EmitContext.Mark): Just pass the arguments to
292 ILGenerator.MarkSequencePoint() which are actually used by the
295 2003-02-09 Martin Baulig <martin@ximian.com>
297 * location.cs (SourceFile): New public sealed class. This
298 contains the name and an index which is used in the location's token.
299 (Location): Reserve an appropriate number of bits in the token for
300 the source file instead of walking over that list, this gives us a
301 really huge performance improvement when compiling with debugging.
303 * driver.cs (Driver.parse, Driver.tokenize_file): Take a
304 `SourceFile' argument instead of a string.
305 (Driver.ProcessFile): Add all the files via Location.AddFile(),
306 but don't parse/tokenize here, we need to generate the list of all
307 source files before we do that.
308 (Driver.ProcessFiles): New static function. Parses/tokenizes all
311 * cs-parser.jay (CSharpParser): Take a `SourceFile' argument
314 * cs-tokenizer.cs (Tokenizer): Take `SourceFile' argument instead
317 2003-02-09 Martin Baulig <martin@ximian.com>
319 * cs-tokenizer.cs (Tokenizer.PreProcessLine): Also reset the
320 filename on `#line default'.
322 Sat Feb 8 17:03:16 CET 2003 Paolo Molaro <lupus@ximian.com>
324 * statement.cs: don't clear the pinned var when the fixed statement
325 returns from the method (fixes bug#37752).
327 Sat Feb 8 12:58:06 CET 2003 Paolo Molaro <lupus@ximian.com>
329 * typemanager.cs: fix from mathpup@mylinuxisp.com (Marcus Urban)
332 2003-02-07 Martin Baulig <martin@ximian.com>
334 * driver.cs: Removed the `--debug-args' command line argument.
336 * codegen.cs (CodeGen.SaveSymbols): Removed, this is now done
337 automatically by the AsssemblyBuilder.
338 (CodeGen.InitializeSymbolWriter): We don't need to call any
339 initialization function on the symbol writer anymore. This method
340 doesn't take any arguments.
342 2003-02-03 Miguel de Icaza <miguel@ximian.com>
344 * driver.cs: (AddAssemblyAndDeps, LoadAssembly): Enter the types
345 from referenced assemblies as well.
347 2003-02-02 Martin Baulig <martin@ximian.com>
349 * class.cs (MethodData.Emit): Generate debugging info for external methods.
351 2003-02-02 Martin Baulig <martin@ximian.com>
353 * class.cs (Constructor.Emit): Open the symbol writer before
354 emitting the constructor initializer.
355 (ConstructorInitializer.Emit): Call ec.Mark() to allow
356 single-stepping through constructor initializers.
358 2003-01-30 Miguel de Icaza <miguel@ximian.com>
360 * class.cs: Handle error 549: do not allow virtual methods in
363 2003-02-01 Jackson Harper <jackson@latitudegeo.com>
365 * decl.cs: Check access levels when resolving types
367 2003-01-31 Jackson Harper <jackson@latitudegeo.com>
369 * statement.cs: Add parameters and locals set in catch blocks that might
372 2003-01-29 Miguel de Icaza <miguel@ximian.com>
374 * class.cs (Operator): Set the SpecialName flags for operators.
376 * expression.cs (Invocation.DoResolve): Only block calls to
377 accessors and operators on SpecialName methods.
379 (Cast.TryReduce): Handle conversions from char constants.
382 Tue Jan 28 17:30:57 CET 2003 Paolo Molaro <lupus@ximian.com>
384 * statement.cs: small memory and time optimization in FlowBranching.
386 2003-01-28 Pedro Mart <yoros@wanadoo.es>
388 * expression.cs (IndexerAccess.DoResolveLValue): Resolve the same
389 problem that the last fix but in the other sid (Set).
391 * expression.cs (IndexerAccess.DoResolve): Fix a problem with a null
392 access when there is no indexer in the hierarchy.
394 2003-01-27 Jackson Harper <jackson@latitudegeo.com>
396 * class.cs: Combine some if statements.
398 2003-01-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
400 * driver.cs: fixed bug #37187.
402 2003-01-27 Pedro Martinez Juliá <yoros@wanadoo.es>
404 * expression.cs (IndexerAccess.DoResolve): Before trying to resolve
405 any indexer, it's needed to build a list with all the indexers in the
406 hierarchy (AllGetters), else we have problems. Fixes #35653.
408 2003-01-23 Miguel de Icaza <miguel@ximian.com>
410 * class.cs (MethodData.Define): It is wrong for an interface
411 implementation to be static in both cases: explicit and implicit.
412 We were only handling this in one case.
414 Improve the if situation there to not have negations.
416 * class.cs (Field.Define): Turns out that we do not need to check
417 the unsafe bit on field definition, only on usage. Remove the test.
419 2003-01-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
421 * driver.cs: use assembly.Location instead of Codebase (the latest
422 patch made mcs fail when using MS assemblies).
424 2003-01-21 Tim Haynes <thaynes@openlinksw.com>
426 * driver.cs: use DirectorySeparatorChar instead of a hardcoded "/" to
427 get the path to *corlib.dll.
429 2003-01-21 Nick Drochak <ndrochak@gol.com>
433 * typemanager.cs: Remove compiler warnings
435 2003-01-20 Duncan Mak <duncan@ximian.com>
437 * AssemblyInfo.cs: Bump the version number to 0.19.
439 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
441 * cs-tokenizer.cs: little fixes to line numbering when #line is used.
443 2003-01-18 Zoltan Varga <vargaz@freemail.hu>
445 * class.cs (Constructor::Emit): Emit debugging info for constructors.
447 2003-01-17 Miguel de Icaza <miguel@ximian.com>
449 * cs-parser.jay: Small fix: we were not comparing the constructor
450 name correctly. Thanks to Zoltan for the initial pointer.
452 2003-01-16 Jackson Harper <jackson@latitudegeo.com>
454 * cs-tokenizer.cs: Set file name when specified with #line
456 2003-01-15 Miguel de Icaza <miguel@ximian.com>
458 * cs-parser.jay: Only perform the constructor checks here if we
459 are named like the class; This will help provider a better
460 error. The constructor path is taken when a type definition is
461 not found, but most likely the user forgot to add the type, so
462 report that rather than the constructor error.
464 Tue Jan 14 10:36:49 CET 2003 Paolo Molaro <lupus@ximian.com>
466 * class.cs, rootcontext.cs: small changes to avoid unnecessary memory
469 2003-01-13 Jackson Harper <jackson@latitudegeo.com>
471 * cs-parser.jay: Add cleanup call.
473 2003-01-13 Duncan Mak <duncan@ximian.com>
475 * cs-tokenizer.cs (Cleanup): Rename to 'cleanup' to make it more
476 consistent with other methods.
478 2003-01-13 Jackson Harper <jackson@latitudegeo.com>
480 * cs-tokenizer.cs: Add Cleanup method, also fix #region error messages.
482 Sun Jan 12 19:58:42 CET 2003 Paolo Molaro <lupus@ximian.com>
484 * attribute.cs: only set GuidAttr to true when we have a
487 2003-01-09 Gonzalo Paniagua Javier <gonzalo@ximian.com>
491 * typemanager.cs: fixes to allow mcs compile corlib with the new
492 Type.IsSubclassOf fix.
494 2003-01-08 Miguel de Icaza <miguel@ximian.com>
496 * expression.cs (LocalVariableReference.DoResolve): Classify a
497 constant as a value, not as a variable. Also, set the type for
500 * cs-parser.jay (fixed_statement): take a type instead of a
501 pointer_type, so we can produce a better error message later.
503 * statement.cs (Fixed.Resolve): Flag types that are not pointers
506 (For.DoEmit): Make inifinite loops have a
507 non-conditional branch back.
509 (Fixed.DoEmit): First populate the pinned variables, then emit the
510 statement, then clear the variables. Before I was emitting the
511 code once for each fixed piece.
514 2003-01-08 Martin Baulig <martin@ximian.com>
516 * statement.cs (FlowBranching.MergeChild): A break in a
517 SWITCH_SECTION does not leave a loop. Fixes #36155.
519 2003-01-08 Martin Baulig <martin@ximian.com>
521 * statement.cs (FlowBranching.CheckOutParameters): `struct_params'
522 lives in the same number space than `param_map'. Fixes #36154.
524 2003-01-07 Miguel de Icaza <miguel@ximian.com>
526 * cs-parser.jay (constructor_declaration): Set the
527 Constructor.ModFlags before probing for it. This makes the
528 compiler report 514, 515 and 132 (the code was there, but got
531 * statement.cs (Goto.Resolve): Set `Returns' to ALWAYS.
532 (GotoDefault.Resolve): Set `Returns' to ALWAYS.
533 (GotoCase.Resolve): Set `Returns' to ALWAYS.
535 Tue Jan 7 18:32:24 CET 2003 Paolo Molaro <lupus@ximian.com>
537 * enum.cs: create the enum static fields using the enum type.
539 Tue Jan 7 18:23:44 CET 2003 Paolo Molaro <lupus@ximian.com>
541 * class.cs: don't try to create the ParamBuilder for the return
542 type if it's not needed (and handle it breaking for the ms runtime
545 2003-01-06 Jackson Harper <jackson@latitudegeo.com>
547 * cs-tokenizer.cs: Add REGION flag to #region directives, and add checks to make sure that regions are being poped correctly
549 2002-12-29 Miguel de Icaza <miguel@ximian.com>
551 * cs-tokenizer.cs (get_cmd_arg): Fixups to allow \r to terminate
552 the command. This showed up while compiling the JANET source
553 code, which used \r as its only newline separator.
555 2002-12-28 Miguel de Icaza <miguel@ximian.com>
557 * class.cs (Method.Define): If we are an operator (because it
558 reuses our code), then set the SpecialName and HideBySig. #36128
560 2002-12-22 Miguel de Icaza <miguel@ximian.com>
562 * ecore.cs (FieldExpr.DoResolve): Instead of throwing an
563 exception, report error 120 `object reference required'.
565 * driver.cs: Add --pause option, used during to measure the size
566 of the process as it goes with --timestamp.
568 * expression.cs (Invocation.DoResolve): Do not allow methods with
569 SpecialName to be invoked.
571 2002-12-21 Miguel de Icaza <miguel@ximian.com>
573 * cs-tokenizer.cs: Small fix to the parser: compute the ascii
574 number before adding it.
576 2002-12-21 Ravi Pratap <ravi@ximian.com>
578 * ecore.cs (StandardImplicitConversion): When in an unsafe
579 context, we allow conversion between void * to any other pointer
580 type. This fixes bug #35973.
582 2002-12-20 Jackson Harper <jackson@latitudegeo.com>
584 * codegen.cs: Use Path.GetFileNameWithoutExtension so an exception
585 is not thrown when extensionless outputs are used
587 2002-12-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
589 * rootcontext.cs: fixed compilation of corlib.
591 2002-12-19 Miguel de Icaza <miguel@ximian.com>
593 * attribute.cs (Attributes.Contains): Add new method.
595 * class.cs (MethodCore.LabelParameters): if the parameter is an
596 `out' parameter, check that no attribute `[In]' has been passed.
598 * enum.cs: Handle the `value__' name in an enumeration.
600 2002-12-14 Jaroslaw Kowalski <jarek@atm.com.pl>
602 * decl.cs: Added special case to allow overrides on "protected
605 2002-12-18 Ravi Pratap <ravi@ximian.com>
607 * attribute.cs (Attributes.AddAttributeSection): Rename to this
608 since it makes much more sense.
610 (Attributes.ctor): Don't require a Location parameter.
612 * rootcontext.cs (AddGlobalAttributeSection): Rename again.
614 * attribute.cs (ApplyAttributes): Remove extra Location parameters
615 since we already have that information per attribute.
617 * everywhere : make appropriate changes.
619 * class.cs (LabelParameters): Write the code which actually
620 applies attributes to the return type. We can't do this on the MS
621 .NET runtime so we flag a warning in the case an exception is
624 2002-12-18 Miguel de Icaza <miguel@ximian.com>
626 * const.cs: Handle implicit null conversions here too.
628 2002-12-17 Ravi Pratap <ravi@ximian.com>
630 * class.cs (MethodCore.LabelParameters): Remove the extra
631 Type [] parameter since it is completely unnecessary. Instead
632 pass in the method's attributes so that we can extract
633 the "return" attribute.
635 2002-12-17 Miguel de Icaza <miguel@ximian.com>
637 * cs-parser.jay (parse): Use Report.Error to flag errors instead
638 of ignoring it and letting the compile continue.
640 * typemanager.cs (ChangeType): use an extra argument to return an
641 error condition instead of throwing an exception.
643 2002-12-15 Miguel de Icaza <miguel@ximian.com>
645 * expression.cs (Unary.TryReduce): mimic the code for the regular
646 code path. Perform an implicit cast in the cases where we can
647 implicitly convert to one of the integral types, and then reduce
648 based on that constant. This fixes bug #35483.
650 2002-12-14 Gonzalo Paniagua Javier <gonzalo@ximian.com>
652 * typemanager.cs: fixed cut & paste error in GetRemoveMethod.
654 2002-12-13 Gonzalo Paniagua Javier <gonzalo@ximian.com>
656 * namespace.cs: fixed bug #35489.
658 2002-12-12 Miguel de Icaza <miguel@ximian.com>
660 * class.cs: Remove some dead code.
662 * cs-parser.jay: Estimate the number of methods needed
663 (RootContext.MethodCount);
665 * cs-tokenizer.cs: Use char arrays for parsing identifiers and
666 numbers instead of StringBuilders.
668 * support.cs (PtrHashtable): Add constructor with initial size;
669 We can now reduce reallocations of the method table.
671 2002-12-10 Ravi Pratap <ravi@ximian.com>
673 * attribute.cs (ApplyAttributes): Keep track of the emitted
674 attributes on a per-target basis. This fixes bug #35413.
676 2002-12-10 Miguel de Icaza <miguel@ximian.com>
678 * driver.cs (MainDriver): On rotor encoding 28591 does not exist,
679 default to the Windows 1252 encoding.
681 (UnixParseOption): Support version, thanks to Alp for the missing
684 * AssemblyInfo.cs: Add nice assembly information.
686 * cs-tokenizer.cs: Add fix from Felix to the #if/#else handler
689 * cs-parser.jay: Allow a trailing comma before the close bracked
690 in the attribute_section production.
692 * ecore.cs (FieldExpr.AddressOf): Until I figure out why the
693 address of the instance was being taken, I will take this out,
694 because we take the address of the object immediately here.
696 2002-12-09 Ravi Pratap <ravi@ximian.com>
698 * typemanager.cs (AreMultipleAllowed): Take care of the most
699 obvious case where attribute type is not in the current assembly -
702 2002-12-08 Miguel de Icaza <miguel@ximian.com>
704 * ecore.cs (SimpleName.DoResolve): First perform lookups on using
705 definitions, instead of doing that afterwards.
707 Also we use a nice little hack, depending on the constructor, we
708 know if we are a "composed" name or a simple name. Hence, we
709 avoid the IndexOf test, and we avoid
711 * codegen.cs: Add code to assist in a bug reporter to track down
712 the source of a compiler crash.
714 2002-12-07 Ravi Pratap <ravi@ximian.com>
716 * attribute.cs (Attribute.ApplyAttributes) : Keep track of which attribute
717 types have been emitted for a given element and flag an error
718 if something which does not have AllowMultiple set is used more
721 * typemanager.cs (RegisterAttributeAllowMultiple): Keep track of
722 attribute types and their corresponding AllowMultiple properties
724 (AreMultipleAllowed): Check the property for a given type.
726 * attribute.cs (Attribute.ApplyAttributes): Register the AllowMultiple
727 property in the case we have a TypeContainer.
729 (Attributes.AddAttribute): Detect duplicates and just skip on
730 adding them. This trivial fix catches a pretty gross error in our
731 attribute emission - global attributes were being emitted twice!
733 Bugzilla bug #33187 is now fixed.
735 2002-12-06 Miguel de Icaza <miguel@ximian.com>
737 * cs-tokenizer.cs (pp_expr): Properly recurse here (use pp_expr
740 * expression.cs (Binary.ResolveOperator): I can only use the
741 Concat (string, string, string) and Concat (string, string,
742 string, string) if the child is actually a concatenation of
745 2002-12-04 Miguel de Icaza <miguel@ximian.com>
747 * cs-tokenizer.cs: Small fix, because decimal_digits is used in a
748 context where we need a 2-character lookahead.
750 * pending.cs (PendingImplementation): Rework so we can keep track
751 of interface types all the time, and flag those which were
752 implemented by parents as optional.
754 2002-12-03 Miguel de Icaza <miguel@ximian.com>
756 * expression.cs (Binary.ResolveOperator): Use
757 String.Concat(string,string,string) or
758 String.Concat(string,string,string,string) when possible.
760 * typemanager: More helper methods.
763 Tue Dec 3 19:32:04 CET 2002 Paolo Molaro <lupus@ximian.com>
765 * pending.cs: remove the bogus return from GetMissingInterfaces()
766 (see the 2002-11-06 entry: the mono runtime is now fixed in cvs).
768 2002-12-02 Gonzalo Paniagua Javier <gonzalo@ximian.com>
770 * namespace.cs: avoid duplicated 'using xxx' being added to
771 using_clauses. This prevents mcs from issuing and 'ambiguous type' error
772 when we get more than one 'using' statement for the same namespace.
773 Report a CS0105 warning for it.
775 2002-11-30 Miguel de Icaza <miguel@ximian.com>
777 * cs-tokenizer.cs (consume_identifier): use read directly, instead
778 of calling getChar/putback, uses internal knowledge of it.
780 (xtoken): Reorder tokenizer so most common patterns are checked
781 first. This reduces the compilation time in another 5% (from 8.11s
782 average to 7.73s for bootstrapping mcs on my Mobile p4/1.8ghz).
784 The parsing time is 22% of the compilation in mcs, and from that
785 64% is spent on the tokenization process.
787 I tried using a binary search for keywords, but this is slower
788 than the hashtable. Another option would be to do a couple of
791 * Not use a StringBuilder, instead use an array of chars,
792 with a set value. Notice that this way we could catch
793 the 645 error without having to do it *afterwards*.
795 * We could write a hand-parser to avoid the hashtable
798 The identifier consumption process takes 37% of the tokenization
799 time. Another 15% is spent on is_number. 56% of the time spent
800 on is_number is spent on Int64.Parse:
802 * We could probably choose based on the string length to
803 use Int32.Parse or Int64.Parse and avoid all the 64-bit
806 Another 3% is spend on wrapping `xtoken' in the `token' function.
808 Handle 0xa0 as whitespace (#34752)
810 2002-11-26 Miguel de Icaza <miguel@ximian.com>
812 * typemanager.cs (IsCLRType): New routine to tell whether a type
813 is one of the builtin types.
815 Maybe it needs to use TypeCodes to be faster. Maybe we could use
816 typecode in more places instead of doing pointer comparissions.
817 We could leverage some knowledge about the way the typecodes are
820 New code to cache namespaces in assemblies, it is currently not
821 invoked, to be used soon.
823 * decl.cs (DeclSpace.MakeFQN): Simple optimization.
825 * expression.cs (Binary.ResolveOperator): specially handle
826 strings, and do not perform user-defined operator overloading for
829 2002-11-24 Miguel de Icaza <miguel@ximian.com>
831 * cs-tokenizer.cs: Avoid calling Char.IsDigit which is an
832 internalcall as it is a pretty simple operation; Avoid whenever
833 possible to call Char.IsLetter.
835 (consume_identifier): Cut by half the number of
836 hashtable calls by merging the is_keyword and GetKeyword behavior.
838 Do not short-circuit, because if we do, we
839 report errors (ie, #if false && true would produce an invalid
843 2002-11-24 Martin Baulig <martin@ximian.com>
845 * expression.cs (Cast.TryReduce): If we're in checked syntax,
846 check constant ranges and report a CS0221. Fixes #33186.
848 2002-11-24 Martin Baulig <martin@ximian.com>
850 * cs-parser.jay: Make this work for uninitialized variable
851 declarations in the `for' initializer. Fixes #32416.
853 2002-11-24 Martin Baulig <martin@ximian.com>
855 * ecore.cs (Expression.ConvertExplicit): Make casting from/to
856 System.Enum actually work. Fixes bug #32269, added verify-6.cs.
858 2002-11-24 Martin Baulig <martin@ximian.com>
860 * expression.cs (Binary.DoNumericPromotions): Added `check_user_conv'
861 argument; if true, we also check for user-defined conversions.
862 This is only needed if both arguments are of a user-defined type.
863 Fixes #30443, added test-175.cs.
864 (Binary.ForceConversion): Pass the location argument to ConvertImplicit.
866 * ecore.cs (Expression.ImplicitUserConversionExists): New method.
868 2002-11-24 Martin Baulig <martin@ximian.com>
870 * expression.cs (ArrayAccess.GetStoreOpcode): New public static
871 function to get the store opcode.
872 (Invocation.EmitParams): Call ArrayAccess.GetStoreOpcode() and
873 only emit the Ldelema if the store opcode is Stobj. You must run
874 both test-34 and test-167 to test this. Fixes #34529.
876 2002-11-23 Martin Baulig <martin@ximian.com>
878 * ecore.cs (Expression.MemberLookup): Added additional
879 `qualifier_type' argument which is used when we're being called
880 from MemberAccess.DoResolve() and null if we're called from a
882 (Expression.MemberLookupFailed): New method to report errors; this
883 does the CS1540 check and reports the correct error message.
885 * typemanager.cs (MemberLookup): Added additional `qualifier_type'
886 argument for the CS1540 check and redone the way how we're dealing
887 with private members. See the comment in the source code for details.
888 (FilterWithClosure): Reverted this back to revision 1.197; renamed
889 `closure_start_type' to `closure_qualifier_type' and check whether
890 it's not null. It was not this filter being broken, it was just
891 being called with the wrong arguments.
893 * expression.cs (MemberAccess.DoResolve): use MemberLookupFinal()
894 and pass it the correct `qualifier_type'; this also does the error
897 2002-11-22 Miguel de Icaza <miguel@ximian.com>
899 * expression.cs (Invocation.EmitParams): If the we are dealing
900 with a non-built-in value type, load its address as well.
902 (ArrayCreation): Use a a pretty constant instead
903 of the hardcoded value 2. Use 6 instead of 2 for the number of
906 (ArrayCreation.EmitDynamicInitializers): Peel enumerations,
907 because they are not really value types, just glorified integers.
909 * driver.cs: Do not append .exe, the CSC compiler does not do it.
911 * ecore.cs: Remove redundant code for enumerations, make them use
912 the same code path as everything else, fixes the casting issue
913 with enumerations in Windows.Forms.
915 * attribute.cs: Do only cast to string if it is a string, the
916 validation happens later.
918 * typemanager.cs: Temproary hack to avoid a bootstrap issue until
919 people upgrade their corlibs.
921 * ecore.cs: Oops, enumerations were not following the entire code path
923 2002-11-21 Miguel de Icaza <miguel@ximian.com>
925 * typemanager.cs (FilterWithClosure): Commented out the test for
926 1540 in typemanager.cs, as it has problems when accessing
927 protected methods from a parent class (see test-174.cs).
929 * attribute.cs (Attribute.ValidateGuid): new method.
930 (Attribute.Resolve): Use above.
932 2002-11-19 Miguel de Icaza <miguel@ximian.com>
934 * enum.cs: In FindMembers, perform a recursive lookup for values. (34308)
936 * ecore.cs (SimpleName.SimpleNameResolve): Remove the special
937 handling for enumerations, as we only needed the TypeContainer
938 functionality to begin with (this is required for the fix below to
939 work for enums that reference constants in a container class for
942 * codegen.cs (EmitContext): Make TypeContainer a DeclSpace.
944 * enum.cs (Enum.Define): Use `this' instead of parent, so we have
945 a valid TypeBuilder to perform lookups on.o
947 * class.cs (InheritableMemberSignatureCompare): Use true in the
948 call to GetGetMethod and GetSetMethod, because we are comparing
949 the signature, and we need to get the methods *even* if they are
952 (PropertyBase.CheckBase): ditto.
954 * statement.cs (Switch.ResolveAndReduce, Block.EmitMeta,
955 GotoCase.Resolve): Use Peel on EmpytCasts.
957 * ecore.cs (EmptyCast): drop child, add Peel method.
959 2002-11-17 Martin Baulig <martin@ximian.com>
961 * ecore.cs (EmptyCast.Child): New public property.
963 * statement.cs (SwitchLabel.ResolveAndReduce): Check whether the
964 label resolved to an EmptyCast. Fixes #34162.
965 (GotoCase.Resolve): Likewise.
966 (Block.EmitMeta): Likewise.
968 2002-11-17 Martin Baulig <martin@ximian.com>
970 * expression.cs (Invocation.BetterConversion): Prefer int over
971 uint; short over ushort; long over ulong for integer literals.
972 Use ImplicitConversionExists instead of StandardConversionExists
973 since we also need to check for user-defined implicit conversions.
974 Fixes #34165. Added test-173.cs.
976 2002-11-16 Martin Baulig <martin@ximian.com>
978 * expression.cs (Binary.EmitBranchable): Eliminate comparisions
979 with the `true' and `false' literals. Fixes #33151.
981 2002-11-16 Martin Baulig <martin@ximian.com>
983 * typemanager.cs (RealMemberLookup): Reverted Miguel's patch from
984 October 22nd; don't do the cs1540 check for static members.
986 * ecore.cs (PropertyExpr.ResolveAccessors): Rewrote this; we're
987 now using our own filter here and doing the cs1540 check again.
989 2002-11-16 Martin Baulig <martin@ximian.com>
991 * support.cs (InternalParameters): Don't crash if we don't have
992 any fixed parameters. Fixes #33532.
994 2002-11-16 Martin Baulig <martin@ximian.com>
996 * decl.cs (MemberCache.AddMethods): Use BindingFlags.FlattenHierarchy
997 when looking up static methods to make this work on Windows.
1000 2002-11-16 Martin Baulig <martin@ximian.com>
1002 * ecore.cs (PropertyExpr.VerifyAssignable): Check whether we have
1003 a setter rather than using PropertyInfo.CanWrite.
1005 2002-11-15 Nick Drochak <ndrochak@gol.com>
1007 * class.cs: Allow acces to block member by subclasses. Fixes build
1010 2002-11-14 Martin Baulig <martin@ximian.com>
1012 * class.cs (Constructor.Emit): Added the extern/block check.
1015 2002-11-14 Martin Baulig <martin@ximian.com>
1017 * expression.cs (IndexerAccess.DoResolve): Do a DeclaredOnly
1018 iteration while looking for indexers, this is needed because the
1019 indexer may have a different name in our base classes. Fixed the
1020 error reporting (no indexers at all, not get accessor, no
1021 overloaded match). Fixes bug #33089.
1022 (IndexerAccess.DoResolveLValue): Likewise.
1024 2002-11-14 Martin Baulig <martin@ximian.com>
1026 * class.cs (PropertyBase.CheckBase): Make this work for multiple
1027 indexers. Fixes the first part of bug #33089.
1028 (MethodSignature.InheritableMemberSignatureCompare): Added support
1031 2002-11-13 Ravi Pratap <ravi@ximian.com>
1033 * attribute.cs (Attribute.Resolve): Catch the
1034 NullReferenceException and report it since it isn't supposed to
1037 2002-11-12 Miguel de Icaza <miguel@ximian.com>
1039 * expression.cs (Binary.EmitBranchable): Also handle the cases for
1040 LogicalOr and LogicalAnd that can benefit from recursively
1041 handling EmitBranchable. The code now should be nice for Paolo.
1043 2002-11-08 Miguel de Icaza <miguel@ximian.com>
1045 * typemanager.cs (LookupType): Added a negative-hit hashtable for
1046 the Type lookups, as we perform quite a number of lookups on
1047 non-Types. This can be removed once we can deterministically tell
1048 whether we have a type or a namespace in advance.
1050 But this might require special hacks from our corlib.
1054 * ecore.cs (TryImplicitIntConversion): Handle conversions to float
1055 and double which avoids a conversion from an integer to a double.
1057 * expression.cs: tiny optimization, avoid calling IsConstant,
1058 because it effectively performs the lookup twice.
1060 2002-11-06 Miguel de Icaza <miguel@ximian.com>
1062 But a bogus return here to keep the semantics of the old code
1063 until the Mono runtime is fixed.
1065 * pending.cs (GetMissingInterfaces): New method used to remove all
1066 the interfaces that are already implemented by our parent
1067 classes from the list of pending methods.
1069 * interface.cs: Add checks for calls after ResolveTypeExpr.
1071 2002-11-05 Miguel de Icaza <miguel@ximian.com>
1073 * class.cs (Class.Emit): Report warning 67: event not used if the
1074 warning level is beyond 3.
1076 * ecore.cs (Expression.ConvertExplicit): Missed a check for expr
1077 being a NullLiteral.
1079 * cs-parser.jay: Fix, Gonzalo reverted the order of the rank
1082 * class.cs (TypeContainer.GetClassBases): Cover a missing code
1083 path that might fail if a type can not be resolved.
1085 * expression.cs (Binary.Emit): Emit unsigned versions of the
1088 * driver.cs: use error 5.
1090 2002-11-02 Gonzalo Paniagua Javier <gonzalo@gnome-db.org>
1092 * cs-parser.jay: simplified a rule and 5 SR conflicts dissapeared.
1094 2002-11-01 Miguel de Icaza <miguel@ximian.com>
1096 * cs-parser.jay (switch_section): A beautiful patch from Martin
1097 Baulig that fixed 33094.
1099 2002-10-31 Miguel de Icaza <miguel@ximian.com>
1101 * ecore.cs (PropertyExpr.DoResolveLValue, PropertyExpr.DoResolve):
1102 Check whether the base is abstract and report an error if so.
1104 * expression.cs (IndexerAccess.DoResolveLValue,
1105 IndexerAccess.DoResolve): ditto.
1107 (Invocation.DoResolve): ditto.
1109 (Invocation.FullMethodDesc): Improve the report string.
1111 * statement.cs (Block): Eliminate IsVariableDefined as it is
1112 basically just a wrapper for GetVariableInfo.
1114 * ecore.cs (SimpleName): Use new
1116 * support.cs (ReflectionParamter.ParameterType): We unwrap the
1117 type, as we return the actual parameter ref/unref state on a
1120 2002-10-30 Miguel de Icaza <miguel@ximian.com>
1122 * support.cs: Return proper flags REF/OUT fixing the previous
1125 * expression.cs: Reverted last patch, that was wrong. Is_ref is
1126 not used to mean `ref' but `ref or out' in ParameterReference
1128 * delegate.cs (FullDelegateDesc): use ParameterDesc to get the
1129 full type signature instead of calling TypeManger.CSharpName
1132 * support.cs (InternalParameters.ParameterDesc): Do not compare
1133 directly to the modflags, because REF/OUT will actually be bitsets
1136 * delegate.cs (VerifyMethod): Check also the modifiers.
1138 * cs-tokenizer.cs: Fix bug where floating point values with an
1139 exponent where a sign was missing was ignored.
1141 * driver.cs: Allow multiple assemblies to be specified in a single
1144 2002-10-28 Miguel de Icaza <miguel@ximian.com>
1146 * cs-parser.jay: Ugly. We had to add a multiplicative_expression,
1147 because identifiers after a parenthesis would end up in this kind
1148 of production, and we needed to desamiguate it for having casts
1151 (UserDefinedType *) xxx
1153 2002-10-24 Miguel de Icaza <miguel@ximian.com>
1155 * typemanager.cs (RealMemberLookup): when we deal with a subclass,
1156 we should set on the Bindingflags.NonPublic, but not turn on
1157 private_ok. private_ok controls whether a Private member is
1158 returned (this is chekced on the filter routine), while the
1159 BindingFlags.NonPublic just controls whether private/protected
1160 will be allowed. This fixes the problem part of the problem of
1161 private properties being allowed to be used in derived classes.
1163 * expression.cs (BaseAccess): Provide an DoResolveLValue method,
1164 so we can call the children DoResolveLValue method (this will
1165 properly signal errors on lvalue assignments to base properties)
1167 * ecore.cs (PropertyExpr.ResolveAccessors): If both setter and
1168 getter are null, and we have a property info, we know that this
1169 happened because the lookup failed, so we report an error 122 for
1170 protection level violation.
1172 We also silently return if setter and getter are null in the
1173 resolve functions, this condition only happens if we have flagged
1174 the error before. This is the other half of the problem.
1176 (PropertyExpr.ResolveAccessors): Turns out that PropertyInfo does
1177 not have accessibility information, that is why we were returning
1178 true in the filter function in typemanager.cs.
1180 To properly report 122 (property is inaccessible because of its
1181 protection level) correctly, we report this error in ResolveAccess
1182 by failing if both the setter and the getter are lacking (ie, the
1185 DoResolve and DoLResolve have been modified to check for both
1186 setter/getter being null and returning silently, the reason being
1187 that I did not want to put the knowledge about this error in upper
1190 int old = Report.Errors;
1191 x = new PropertyExpr (...);
1192 if (old != Report.Errors)
1197 So the property expr is returned, but it is invalid, so the error
1198 will be flagged during the resolve process.
1200 * class.cs: Remove InheritablePropertySignatureCompare from the
1201 class, as we no longer depend on the property signature to compute
1202 whether it is possible to implement a method or not.
1204 The reason is that calling PropertyInfo.GetGetMethod will return
1205 null (in .NET, in Mono it works, and we should change this), in
1206 cases where the Get Method does not exist in that particular
1211 class X { public virtual int A { get { return 1; } } }
1213 class Z : Y { public override int A { get { return 2; } } }
1215 Would fail in Z because the parent (Y) would not have the property
1216 defined. So we avoid this completely now (because the alternative
1217 fix was ugly and slow), and we now depend exclusively on the
1220 (PropertyBase.CheckBase): Use a method-base mechanism to find our
1221 reference method, instead of using the property.
1223 * typemanager.cs (GetPropertyGetter, GetPropertySetter): These
1224 routines are gone now.
1226 * typemanager.cs (GetPropertyGetter, GetPropertySetter): swap the
1227 names, they were incorrectly named.
1229 * cs-tokenizer.cs: Return are more gentle token on failure.
1231 * pending.cs (PendingImplementation.InterfaceMethod): This routine
1232 had an out-of-sync index variable, which caused it to remove from
1233 the list of pending methods the wrong method sometimes.
1235 2002-10-22 Miguel de Icaza <miguel@ximian.com>
1237 * ecore.cs (PropertyExpr): Do not use PropertyInfo.CanRead,
1238 CanWrite, because those refer to this particular instance of the
1239 property, and do not take into account the fact that we can
1240 override single members of a property.
1242 Constructor requires an EmitContext. The resolution process does
1243 not happen here, but we need to compute the accessors before,
1244 because the resolution does not always happen for properties.
1246 * typemanager.cs (RealMemberLookup): Set private_ok if we are a
1247 subclass, before we did not update this flag, but we did update
1250 (GetAccessors): Drop this routine, as it did not work in the
1251 presence of partially overwritten set/get methods.
1253 Notice that this broke the cs1540 detection, but that will require
1256 2002-10-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1260 * driver.cs: issue a warning instead of an error if we don't support
1261 debugging for the platform. Also ignore a couple of errors that may
1262 arise when trying to write the symbols. Undo my previous patch.
1264 2002-10-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1266 * driver.cs: ignore /debug switch except for Unix platforms.
1268 2002-10-23 Nick Drochak <ndrochak@gol.com>
1270 * makefile: Remove mcs2.exe and mcs3.exe on 'make clean'
1272 2002-10-21 Miguel de Icaza <miguel@ximian.com>
1274 * driver.cs: Do not make mcs-debug conditional, so we do not break
1277 * statement.cs (UsageVector.MergeChildren): I would like Martin to
1278 review this patch. But basically after all the children variables
1279 have been merged, the value of "Breaks" was not being set to
1280 new_breaks for Switch blocks. I think that it should be set after
1281 it has executed. Currently I set this to the value of new_breaks,
1282 but only if new_breaks is FlowReturn.ALWAYS, which is a bit
1283 conservative, but I do not understand this code very well.
1285 I did not break anything in the build, so that is good ;-)
1287 * cs-tokenizer.cs: Also allow \r in comments as a line separator.
1289 2002-10-20 Mark Crichton <crichton@gimp.org>
1291 * cfold.cs: Fixed compile blocker. Really fixed it this time.
1293 2002-10-20 Nick Drochak <ndrochak@gol.com>
1295 * cfold.cs: Fixed compile blocker.
1297 2002-10-20 Miguel de Icaza <miguel@ximian.com>
1299 * driver.cs: I was chekcing the key, not the file.
1301 2002-10-19 Ravi Pratap <ravi@ximian.com>
1303 * ecore.cs (UserDefinedConversion): Get rid of the bogus error
1304 message that we were generating - we just need to silently return
1307 2002-10-19 Miguel de Icaza <miguel@ximian.com>
1309 * class.cs (Event.Define): Change my previous commit, as this
1310 breaks the debugger. This is a temporary hack, as it seems like
1311 the compiler is generating events incorrectly to begin with.
1313 * expression.cs (Binary.ResolveOperator): Added support for
1314 "U operator - (E x, E y)"
1316 * cfold.cs (BinaryFold): Added support for "U operator - (E x, E
1319 * ecore.cs (FieldExpr.AddressOf): We had a special code path for
1320 init-only variables, but this path did not take into account that
1321 there might be also instance readonly variables. Correct this
1324 This fixes bug 32253
1326 * delegate.cs (NewDelegate.DoResolve): Catch creation of unsafe
1329 * driver.cs: Change the extension for modules to `netmodule'
1331 * cs-parser.jay: Improved slightly the location tracking for
1332 the debugger symbols.
1334 * class.cs (Event.Define): Use Modifiers.FieldAttr on the
1335 modifiers that were specified instead of the hardcoded value
1336 (FamAndAssem). This was basically ignoring the static modifier,
1337 and others. Fixes 32429.
1339 * statement.cs (Switch.SimpleSwitchEmit): Simplified the code, and
1340 fixed a bug in the process (32476)
1342 * expression.cs (ArrayAccess.EmitAssign): Patch from
1343 hwang_rob@yahoo.ca that fixes bug 31834.3
1345 2002-10-18 Miguel de Icaza <miguel@ximian.com>
1347 * driver.cs: Make the module extension .netmodule.
1349 2002-10-16 Miguel de Icaza <miguel@ximian.com>
1351 * driver.cs: Report an error if the resource file is not found
1352 instead of crashing.
1354 * ecore.cs (PropertyExpr.EmitAssign): Pass IsBase instead of
1355 false, like Emit does.
1357 2002-10-16 Nick Drochak <ndrochak@gol.com>
1359 * typemanager.cs: Remove unused private member. Also reported mcs
1360 bug to report this as a warning like csc.
1362 2002-10-15 Martin Baulig <martin@gnome.org>
1364 * statement.cs (Statement.Emit): Made this a virtual method; emits
1365 the line number info and calls DoEmit().
1366 (Statement.DoEmit): New protected abstract method, formerly knows
1367 as Statement.Emit().
1369 * codegen.cs (EmitContext.Mark): Check whether we have a symbol writer.
1371 2002-10-11 Miguel de Icaza <miguel@ximian.com>
1373 * class.cs: Following the comment from 2002-09-26 to AddMethod, I
1374 have fixed a remaining problem: not every AddXXXX was adding a
1375 fully qualified name.
1377 Now everyone registers a fully qualified name in the DeclSpace as
1378 being defined instead of the partial name.
1380 Downsides: we are slower than we need to be due to the excess
1381 copies and the names being registered this way.
1383 The reason for this is that we currently depend (on the corlib
1384 bootstrap for instance) that types are fully qualified, because
1385 we dump all the types in the namespace, and we should really have
1386 types inserted into the proper namespace, so we can only store the
1387 basenames in the defined_names array.
1389 2002-10-10 Martin Baulig <martin@gnome.org>
1391 * expression.cs (ArrayAccess.EmitStoreOpcode): Reverted the patch
1392 from bug #31834, see the bug report for a testcase which is
1395 2002-10-10 Martin Baulig <martin@gnome.org>
1397 * codegen.cs (EmitContext.Breaks): Removed, we're now using the
1398 flow analysis code for this.
1400 * statement.cs (Do, While, For): Tell the flow analysis code about
1402 (FlowBranching.UsageVector): Added support for infinite loops.
1403 (Block.Resolve): Moved the dead code elimination here and use flow
1406 2002-10-09 Miguel de Icaza <miguel@ximian.com>
1408 * class.cs (Field.Define): Catch cycles on struct type
1411 * typemanager.cs (IsUnmanagedtype): Do not recursively check
1412 fields if the fields are static. We only need to check instance
1415 * expression.cs (As.DoResolve): Test for reference type.
1417 * statement.cs (Using.ResolveExpression): Use
1418 ConvertImplicitRequired, not ConvertImplicit which reports an
1420 (Using.ResolveLocalVariableDecls): ditto.
1422 * expression.cs (Binary.ResolveOperator): Report errors in a few
1423 places where we had to.
1425 * typemanager.cs (IsUnmanagedtype): Finish implementation.
1427 2002-10-08 Miguel de Icaza <miguel@ximian.com>
1429 * expression.cs: Use StoreFromPtr instead of extracting the type
1430 and then trying to use Stelem. Patch is from hwang_rob@yahoo.ca
1432 * ecore.cs (ImplicitReferenceConversion): It is possible to assign
1433 an enumeration value to a System.Enum, but System.Enum is not a
1434 value type, but an class type, so we need to box.
1436 (Expression.ConvertExplicit): One codepath could return
1437 errors but not flag them. Fix this. Fixes #31853
1439 * parameter.cs (Resolve): Do not allow void as a parameter type.
1441 2002-10-06 Martin Baulig <martin@gnome.org>
1443 * statemenc.cs (FlowBranching.SetParameterAssigned): Don't crash
1444 if it's a class type and not a struct. Fixes #31815.
1446 2002-10-06 Martin Baulig <martin@gnome.org>
1448 * statement.cs: Reworked the flow analysis code a bit to make it
1449 usable for dead code elimination.
1451 2002-10-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1453 * cs-parser.jay: allow empty source files. Fixes bug #31781.
1455 2002-10-04 Miguel de Icaza <miguel@ximian.com>
1457 * expression.cs (ComposedCast.DoResolveType): A quick workaround
1458 to fix the test 165, will investigate deeper.
1460 2002-10-04 Martin Baulig <martin@gnome.org>
1462 * statement.cs (FlowBranching.UsageVector.MergeChildren): Make
1463 finally blocks actually work.
1464 (Try.Resolve): We don't need to create a sibling for `finally' if
1465 there is no finally block.
1467 2002-10-04 Martin Baulig <martin@gnome.org>
1469 * class.cs (Constructor.Define): The default accessibility for a
1470 non-default constructor is private, not public.
1472 2002-10-04 Miguel de Icaza <miguel@ximian.com>
1474 * class.cs (Constructor): Make AllowedModifiers public, add
1477 * cs-parser.jay: Perform the modifiers test here, as the
1478 constructor for the Constructor class usually receives a zero
1479 because of the way we create it (first we create, later we
1480 customize, and we were never checking the modifiers).
1482 * typemanager.cs (Typemanager.LookupTypeDirect): This new function
1483 is a version of LookupTypeReflection that includes the type-name
1484 cache. This can be used as a fast path for functions that know
1485 the fully qualified name and are only calling into *.GetType() to
1486 obtain a composed type.
1488 This is also used by TypeManager.LookupType during its type
1491 (LookupType): We now also track the real type name, as sometimes
1492 we can get a quey for the real type name from things like
1493 ComposedCast. This fixes bug 31422.
1495 * expression.cs (ComposedCast.Resolve): Since we are obtaining a
1496 complete type fullname, it does not have to go through the type
1497 resolution system to obtain the composed version of the type (for
1498 obtaining arrays or pointers).
1500 (Conditional.Emit): Use the EmitBoolExpression to
1501 generate nicer code, as requested by Paolo.
1503 (ArrayCreation.CheckIndices): Use the patch from
1504 hwang_rob@yahoo.ca to validate the array initializers.
1506 2002-10-03 Miguel de Icaza <miguel@ximian.com>
1508 * class.cs (ConstructorInitializer.Emit): simplify code by using
1509 Invocation.EmitCall, and at the same time, fix the bugs in calling
1510 parent constructors that took variable arguments.
1512 * ecore.cs (Expression.ConvertNumericExplicit,
1513 Expression.ImplicitNumericConversion): Remove the code that
1514 manually wrapped decimal (InternalTypeConstructor call is now gone
1517 * expression.cs (Cast.TryReduce): Also handle decimal types when
1518 trying to perform a constant fold on the type.
1520 * typemanager.cs (IsUnmanagedtype): Partially implemented.
1522 * parameter.cs: Removed ResolveAndDefine, as it was not needed, as
1523 that only turned off an error report, and did nothing else.
1525 2002-10-02 Miguel de Icaza <miguel@ximian.com>
1527 * driver.cs: Handle and ignore /fullpaths
1529 2002-10-01 Miguel de Icaza <miguel@ximian.com>
1531 * expression.cs (Binary.ResolveOperator): Catch the case where
1532 DoNumericPromotions returns true,
1534 (Binary.DoNumericPromotions): Simplify the code, and the tests.
1536 2002-09-27 Miguel de Icaza <miguel@ximian.com>
1538 * ecore.cs (EventExpr.Emit): Instead of emitting an exception,
1541 2002-09-26 Miguel de Icaza <miguel@ximian.com>
1543 * ecore.cs (ConvertNumericExplicit): It is not enough that the
1544 conversion exists, but it is also required that the conversion be
1545 performed. This manifested in "(Type64Enum) 2".
1547 * class.cs (TypeManager.AddMethod): The fix is not to change
1548 AddEnum, because that one was using a fully qualified name (every
1549 DeclSpace derivative does), but to change the AddMethod routine
1550 that was using an un-namespaced name. This now correctly reports
1551 the duplicated name.
1553 Revert patch until I can properly fix it. The issue
1554 is that we have a shared Type space across all namespaces
1555 currently, which is wrong.
1557 Options include making the Namespace a DeclSpace, and merge
1558 current_namespace/current_container in the parser.
1560 2002-09-25 Miguel de Icaza <miguel@ximian.com>
1562 * cs-parser.jay: Improve error reporting when we get a different
1563 kind of expression in local_variable_type and
1564 local_variable_pointer_type.
1566 Propagate this to avoid missleading errors being reported.
1568 * ecore.cs (ImplicitReferenceConversion): treat
1569 TypeManager.value_type as a target just like object_type. As
1574 Is valid, and needs to result in the int 1 being boxed before it
1575 is assigned to the value type v.
1577 * class.cs (TypeContainer.AddEnum): Use the basename, not the name
1578 to validate the enumeration name.
1580 * expression.cs (ArrayAccess.EmitAssign): Mimic the same test from
1581 EmitDynamicInitializers for the criteria to use Ldelema. Thanks
1582 to hwang_rob@yahoo.ca for finding the bug and providing a patch.
1584 * ecore.cs (TryImplicitIntConversion): When doing an
1585 implicit-enumeration-conversion, check if the type is 64-bits and
1586 perform a conversion before passing to EnumConstant.
1588 2002-09-23 Miguel de Icaza <miguel@ximian.com>
1590 * decl.cs (Error_AmbiguousTypeReference); New routine used to
1591 report ambiguous type references. Unlike the MS version, we
1592 report what the ambiguity is. Innovation at work ;-)
1594 (DeclSpace.FindType): Require a location argument to
1595 display when we display an ambiguous error.
1597 * ecore.cs: (SimpleName.DoResolveType): Pass location to FindType.
1599 * interface.cs (GetInterfaceTypeByName): Pass location to FindType.
1601 * expression.cs (EmitDynamicInitializers): Apply patch from
1602 hwang_rob@yahoo.ca that fixes the order in which we emit our
1605 2002-09-21 Martin Baulig <martin@gnome.org>
1607 * delegate.cs (Delegate.VerifyApplicability): Make this work if the
1608 delegate takes no arguments.
1610 2002-09-20 Miguel de Icaza <miguel@ximian.com>
1612 * constant.cs: Use Conv_U8 instead of Conv_I8 when loading longs
1615 * expression.cs: Extract the underlying type.
1617 * ecore.cs (StoreFromPtr): Use TypeManager.IsEnumType instad of IsEnum
1619 * decl.cs (FindType): Sorry about this, fixed the type lookup bug.
1621 2002-09-19 Miguel de Icaza <miguel@ximian.com>
1623 * class.cs (TypeContainer.DefineType): We can not use the nice
1624 PackingSize with the size set to 1 DefineType method, because it
1625 will not allow us to define the interfaces that the struct
1628 This completes the fixing of bug 27287
1630 * ecore.cs (Expresion.ImplicitReferenceConversion): `class-type S'
1631 means also structs. This fixes part of the problem.
1632 (Expresion.ImplicitReferenceConversionExists): ditto.
1634 * decl.cs (DeclSparce.ResolveType): Only report the type-not-found
1635 error if there were no errors reported during the type lookup
1636 process, to avoid duplicates or redundant errors. Without this
1637 you would get an ambiguous errors plus a type not found. We have
1638 beaten the user enough with the first error.
1640 (DeclSparce.FindType): Emit a warning if we have an ambiguous
1643 * ecore.cs (SimpleName.DoResolveType): If an error is emitted
1644 during the resolution process, stop the lookup, this avoids
1645 repeated error reports (same error twice).
1647 * rootcontext.cs: Emit a warning if we have an ambiguous reference.
1649 * typemanager.cs (LookupType): Redo the type lookup code to match
1650 the needs of System.Reflection.
1652 The issue is that System.Reflection requires references to nested
1653 types to begin with a "+" sign instead of a dot. So toplevel
1654 types look like: "NameSpace.TopLevelClass", and nested ones look
1655 like "Namespace.TopLevelClass+Nested", with arbitrary nesting
1658 2002-09-19 Martin Baulig <martin@gnome.org>
1660 * codegen.cs (EmitContext.EmitTopBlock): If control flow analysis
1661 says that a method always returns or always throws an exception,
1662 don't report the CS0161.
1664 * statement.cs (FlowBranching.UsageVector.MergeChildren): Always
1665 set `Returns = new_returns'.
1667 2002-09-19 Martin Baulig <martin@gnome.org>
1669 * expression.cs (MemberAccess.ResolveMemberAccess): When resolving
1670 to an enum constant, check for a CS0176.
1672 2002-09-18 Miguel de Icaza <miguel@ximian.com>
1674 * class.cs (TypeContainer.CheckPairedOperators): Now we check
1675 for operators that must be in pairs and report errors.
1677 * ecore.cs (SimpleName.DoResolveType): During the initial type
1678 resolution process, when we define types recursively, we must
1679 check first for types in our current scope before we perform
1680 lookups in the enclosing scopes.
1682 * expression.cs (MakeByteBlob): Handle Decimal blobs.
1684 (Invocation.VerifyArgumentsCompat): Call
1685 TypeManager.TypeToCoreType on the parameter_type.GetElementType.
1686 I thought we were supposed to always call this, but there are a
1687 few places in the code where we dont do it.
1689 2002-09-17 Miguel de Icaza <miguel@ximian.com>
1691 * driver.cs: Add support in -linkres and -resource to specify the
1692 name of the identifier.
1694 2002-09-16 Miguel de Icaza <miguel@ximian.com>
1696 * ecore.cs (StandardConversionExists): Sync with the conversion
1697 code: allow anything-* to void* conversions.
1699 (FindMostSpecificSource): Use an Expression argument
1700 instead of a Type, because we might be handed over a Literal which
1701 gets a few more implicit conversions that plain types do not. So
1702 this information was being lost.
1704 Also, we drop the temporary type-holder expression when not
1707 2002-09-17 Martin Baulig <martin@gnome.org>
1709 * class.cs (PropertyBase.CheckBase): Don't check the base class if
1710 this is an explicit interface implementation.
1712 2002-09-17 Martin Baulig <martin@gnome.org>
1714 * class.cs (PropertyBase.CheckBase): Make this work for indexers with
1715 different `IndexerName' attributes.
1717 * expression.cs (BaseIndexerAccess): Rewrote this class to use IndexerAccess.
1718 (IndexerAccess): Added special protected ctor for BaseIndexerAccess and
1719 virtual CommonResolve().
1721 2002-09-16 Miguel de Icaza <miguel@ximian.com>
1723 * enum.cs (LookupEnumValue): Use the EnumConstant declared type,
1724 and convert that to the UnderlyingType.
1726 * statement.cs (Foreach.Resolve): Indexers are just like variables
1727 or PropertyAccesses.
1729 * cs-tokenizer.cs (consume_string): Track line numbers and columns
1730 inside quoted strings, we were not doing this before.
1732 2002-09-16 Martin Baulig <martin@gnome.org>
1734 * ecore.cs (MethodGroupExpr.DoResolve): If we have an instance expression,
1735 resolve it. This is needed for the definite assignment check of the
1736 instance expression, fixes bug #29846.
1737 (PropertyExpr.DoResolve, EventExpr.DoResolve): Likewise.
1739 2002-09-16 Nick Drochak <ndrochak@gol.com>
1741 * parameter.cs: Fix compile error. Cannot reference static member
1742 from an instance object. Is this an mcs bug?
1744 2002-09-14 Martin Baulig <martin@gnome.org>
1746 * decl.cs (MemberCache.SetupCacheForInterface): Don't add an interface
1747 multiple times. Fixes bug #30295, added test-166.cs.
1749 2002-09-14 Martin Baulig <martin@gnome.org>
1751 * statement.cs (Block.Emit): Don't emit unreachable code.
1752 (Switch.SimpleSwitchEmit, Switch.TableSwitchEmit): Check for missing
1754 (Goto.Emit, Continue.Emit): Set ec.Breaks = true.
1756 2002-09-14 Martin Baulig <martin@gnome.org>
1758 * parameter.cs (Parameter.Attributes): Make this work if Modifier.ISBYREF
1761 2002-09-14 Martin Baulig <martin@gnome.org>
1763 * typemanager.cs (TypeManager.IsNestedChildOf): This must return false
1764 if `type == parent' since in this case `type.IsSubclassOf (parent)' will
1765 be false on the ms runtime.
1767 2002-09-13 Martin Baulig <martin@gnome.org>
1769 * ecore.cs (SimpleName.SimpleNameResolve): Include the member name in
1770 the CS0038 error message.
1772 2002-09-12 Miguel de Icaza <miguel@ximian.com>
1774 * expression.cs (CheckedExpr, UnCheckedExpr): If we have a
1775 constant inside, return it.
1777 2002-09-12 Martin Baulig <martin@gnome.org>
1779 * cfold.cs (ConstantFold.DoConstantNumericPromotions): Check whether an
1780 implicit conversion can be done between enum types.
1782 * enum.cs (Enum.LookupEnumValue): If the value is an EnumConstant,
1783 check whether an implicit conversion to the current enum's UnderlyingType
1784 exists and report an error if not.
1786 * codegen.cs (CodeGen.Init): Delete the symbol file when compiling
1787 without debugging support.
1789 * delegate.cs (Delegate.CloseDelegate): Removed, use CloseType instead.
1790 Fixes bug #30235. Thanks to Ricardo Fernández Pascual.
1792 2002-09-12 Martin Baulig <martin@gnome.org>
1794 * typemanager.cs (TypeManager.IsNestedChildOf): New method.
1796 * ecore.cs (IMemberExpr.DeclaringType): New property.
1797 (SimpleName.SimpleNameResolve): Check whether we're accessing a
1798 nonstatic member of an outer type (CS0038).
1800 2002-09-11 Miguel de Icaza <miguel@ximian.com>
1802 * driver.cs: Activate the using-error detector at warning level
1803 4 (at least for MS-compatible APIs).
1805 * namespace.cs (VerifyUsing): Small buglett fix.
1807 * pending.cs (PendingImplementation): pass the container pointer.
1809 * interface.cs (GetMethods): Allow for recursive definition. Long
1810 term, I would like to move every type to support recursive
1811 definitions, not the current ordering mechanism that we have right
1814 The situation is this: Attributes are handled before interfaces,
1815 so we can apply attributes to interfaces. But some attributes
1816 implement interfaces, we will now handle the simple cases
1817 (recursive definitions will just get an error).
1819 * parameter.cs: Only invalidate types at the end if we fail to
1822 2002-09-09 Martin Baulig <martin@gnome.org>
1824 * ecore.cs (PropertyExpr.Emit): Also check for
1825 TypeManager.system_int_array_get_length so this'll also work when
1826 compiling corlib. Fixes #30003.
1828 2002-09-09 Martin Baulig <martin@gnome.org>
1830 * expression.cs (ArrayCreation.MakeByteBlob): Added support for enums
1831 and throw an exception if we can't get the type's size. Fixed #30040,
1834 2002-09-09 Martin Baulig <martin@gnome.org>
1836 * ecore.cs (PropertyExpr.DoResolve): Added check for static properies.
1838 * expression.cs (SizeOf.DoResolve): Sizeof is only allowed in unsafe
1839 context. Fixes bug #30027.
1841 * delegate.cs (NewDelegate.Emit): Use OpCodes.Ldvirtftn for
1842 virtual functions. Fixes bug #30043, added test-164.cs.
1844 2002-09-08 Ravi Pratap <ravi@ximian.com>
1846 * attribute.cs : Fix a small NullRef crash thanks to my stupidity.
1848 2002-09-08 Nick Drochak <ndrochak@gol.com>
1850 * driver.cs: Use an object to get the windows codepage since it's not a
1853 2002-09-08 Miguel de Icaza <miguel@ximian.com>
1855 * statement.cs (For.Emit): for infinite loops (test == null)
1856 return whether there is a break inside, not always "true".
1858 * namespace.cs (UsingEntry): New struct to hold the name of the
1859 using definition, the location where it is defined, and whether it
1860 has been used in a successful type lookup.
1862 * rootcontext.cs (NamespaceLookup): Use UsingEntries instead of
1867 2002-09-06 Ravi Pratap <ravi@ximian.com>
1869 * attribute.cs : Fix incorrect code which relied on catching
1870 a NullReferenceException to detect a null being passed in
1871 where an object was expected.
1873 2002-09-06 Miguel de Icaza <miguel@ximian.com>
1875 * statement.cs (Try): flag the catch variable as assigned
1877 * expression.cs (Cast): Simplified by using ResolveType instead of
1880 * statement.cs (Catch): Fix bug by using ResolveType.
1882 2002-09-06 Ravi Pratap <ravi@ximian.com>
1884 * expression.cs (BetterConversion): Special case for when we have
1885 a NullLiteral as the argument and we have to choose between string
1886 and object types - we choose string the way csc does.
1888 * attribute.cs (Attribute.Resolve): Catch the
1889 NullReferenceException and report error #182 since the Mono
1890 runtime no more has the bug and having this exception raised means
1891 we tried to select a constructor which takes an object and is
1894 2002-09-05 Ravi Pratap <ravi@ximian.com>
1896 * expression.cs (Invocation.OverloadResolve): Flag a nicer error
1897 message (1502, 1503) when we can't locate a method after overload
1898 resolution. This is much more informative and closes the bug
1901 * interface.cs (PopulateMethod): Return if there are no argument
1902 types. Fixes a NullReferenceException bug.
1904 * attribute.cs (Attribute.Resolve): Ensure we allow TypeOf
1905 expressions too. Previously we were checking only in one place for
1906 positional arguments leaving out named arguments.
1908 * ecore.cs (ImplicitNumericConversion): Conversion from underlying
1909 type to the enum type is not allowed. Remove code corresponding to
1912 (ConvertNumericExplicit): Allow explicit conversions from
1913 the underlying type to enum type. This precisely follows the spec
1914 and closes a bug filed by Gonzalo.
1916 2002-09-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1919 * compiler.csproj.user: patch from Adam Chester (achester@bigpond.com).
1921 2002-09-03 Miguel de Icaza <miguel@ximian.com>
1923 * statement.cs (SwitchLabel.ResolveAndReduce): In the string case,
1924 it was important that we stored the right value after the
1925 reduction in `converted'.
1927 2002-09-04 Martin Baulig <martin@gnome.org>
1929 * location.cs (Location.SymbolDocument): Use full pathnames for the
1932 2002-08-30 Miguel de Icaza <miguel@ximian.com>
1934 * expression.cs (ComposedCast): Use DeclSparce.ResolveType instead
1935 of the expression resolve mechanism, because that will catch the
1936 SimpleName error failures.
1938 (Conditional): If we can not resolve the
1939 expression, return, do not crash.
1941 2002-08-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1944 (location): display token name instead of its number.
1946 2002-08-28 Martin Baulig <martin@gnome.org>
1948 * expression.cs (Binary.ResolveOperator): Don't silently return
1949 but return an error if an operator cannot be applied between two
1952 2002-08-28 Martin Baulig <martin@gnome.org>
1954 * class.cs (Constructor.Define): Set the permission attributes
1955 correctly instead of making all constructors public.
1957 2002-08-28 Martin Baulig <martin@gnome.org>
1959 * ecore.cs (Expression.DoResolve): Do a TypeManager.MemberLook
1960 for private members before reporting a CS0103; if we find anything,
1963 2002-08-28 Martin Baulig <martin@gnome.org>
1965 * typemanager.cs (TypeManager.FilterWithClosure): It's not enough
1966 to check whether `closure_start_type == closure_invocation_type',
1967 we also need to check whether `m.DeclaringType == closure_invocation_type'
1968 before bypassing the permission checks. We might be accessing
1969 protected/private members from the base class.
1970 (TypeManager.RealMemberLookup): Only set private_ok if private
1971 members were requested via BindingFlags.NonPublic.
1973 * ecore.cs (MethodGroupExpr.IsExplicitImpl): New property.
1975 * expression.cs (MemberAccess.ResolveMemberAccess): Set
1976 MethodGroupExpr.IsExplicitImpl if appropriate.
1977 (Invocation.DoResolve): Don't report the CS0120 for explicit
1978 interface implementations.
1980 2002-08-27 Martin Baulig <martin@gnome.org>
1982 * expression.cs (Invocation.DoResolve): If this is a static
1983 method and we don't have an InstanceExpression, we must report
1986 2002-08-25 Martin Baulig <martin@gnome.org>
1988 * expression.cs (Binary.ResolveOperator): Don't allow `!=' and
1989 `==' between a valuetype and an object.
1991 2002-08-25 Miguel de Icaza <miguel@ximian.com>
1993 * ecore.cs (TypeExpr): Provide a ToString method.
1995 2002-08-24 Martin Baulig <martin@gnome.org>
1997 * codegen.cs (CodeGen.InitMonoSymbolWriter): The symbol file is
1998 now called proggie.dbg and it's a binary file.
2000 2002-08-23 Martin Baulig <martin@gnome.org>
2002 * decl.cs (MemberCache.AddMethods): Ignore varargs methods.
2004 2002-08-23 Martin Baulig <martin@gnome.org>
2006 * struct.cs (MyStructInfo.ctor): Make this work with empty
2007 structs; it's not allowed to use foreach() on null.
2009 2002-08-23 Martin Baulig <martin@gnome.org>
2011 * codegen.cs (CodeGen.InitMonoSymbolWriter): Tell the symbol
2012 writer the full pathname of the generated assembly.
2014 2002-08-23 Martin Baulig <martin@gnome.org>
2016 * statements.cs (FlowBranching.UsageVector.MergeChildren):
2017 A `finally' block never returns or breaks; improved handling of
2020 2002-08-23 Martin Baulig <martin@gnome.org>
2022 * statement.cs (Throw.Resolve): Allow `throw null'.
2024 2002-08-23 Martin Baulig <martin@gnome.org>
2026 * expression.cs (MemberAccess.ResolveMemberAccess): If this is an
2027 EventExpr, don't do a DeclaredOnly MemberLookup, but check whether
2028 `ee.EventInfo.DeclaringType == ec.ContainerType'. The
2029 MemberLookup would return a wrong event if this is an explicit
2030 interface implementation and the class has an event with the same
2033 2002-08-23 Martin Baulig <martin@gnome.org>
2035 * statement.cs (Block.AddChildVariableNames): New public method.
2036 (Block.AddChildVariableName): Likewise.
2037 (Block.IsVariableNameUsedInChildBlock): Likewise.
2038 (Block.AddVariable): Check whether a variable name has already
2039 been used in a child block.
2041 * cs-parser.jay (declare_local_variables): Mark all variable names
2042 from the current block as being used in a child block in the
2045 2002-08-23 Martin Baulig <martin@gnome.org>
2047 * codegen.cs (CodeGen.InitializeSymbolWriter): Abort if we can't
2048 find the symbol writer.
2050 * driver.cs: csc also allows the arguments to /define being
2051 separated by commas, not only by semicolons.
2053 2002-08-23 Martin Baulig <martin@gnome.org>
2055 * interface.cs (Interface.GetMembers): Added static check for events.
2057 2002-08-15 Martin Baulig <martin@gnome.org>
2059 * class.cs (MethodData.EmitDestructor): In the Expression.MemberLookup
2060 call, use ec.ContainerType.BaseType as queried_type and invocation_type.
2062 * ecore.cs (Expression.MemberLookup): Added documentation and explained
2063 why the MethodData.EmitDestructor() change was necessary.
2065 2002-08-20 Martin Baulig <martin@gnome.org>
2067 * class.cs (TypeContainer.FindMembers): Added static check for events.
2069 * decl.cs (MemberCache.AddMembers): Handle events like normal members.
2071 * typemanager.cs (TypeHandle.GetMembers): When queried for events only,
2072 use Type.GetEvents(), not Type.FindMembers().
2074 2002-08-20 Martin Baulig <martin@gnome.org>
2076 * decl.cs (MemberCache): Added a special method cache which will
2077 be used for method-only searched. This ensures that a method
2078 search will return a MethodInfo with the correct ReflectedType for
2081 2002-08-20 Martin Baulig <martin@gnome.org>
2083 * decl.cs (DeclSpace.FindMembers): Made this public.
2085 2002-08-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2087 * delegate.cs: fixed build on windows.
2088 [FIXME: Filed as bug #29150: MCS must report these errors.]
2090 2002-08-19 Ravi Pratap <ravi@ximian.com>
2092 * ecore.cs (StandardConversionExists): Return a false
2093 if we are trying to convert the void type to anything else
2094 since that is not allowed.
2096 * delegate.cs (DelegateInvocation.DoResolve): Ensure that
2097 we flag error 70 in the event an event is trying to be accessed
2098 directly from outside the declaring type.
2100 2002-08-20 Martin Baulig <martin@gnome.org>
2102 * typemanager.cs, decl.cs: Moved MemberList, IMemberContainer and
2103 MemberCache from typemanager.cs to decl.cs.
2105 2002-08-19 Martin Baulig <martin@gnome.org>
2107 * class.cs (TypeContainer): Implement IMemberContainer.
2108 (TypeContainer.DefineMembers): Create the MemberCache.
2109 (TypeContainer.FindMembers): Do better BindingFlags checking; only
2110 return public members if BindingFlags.Public was given, check
2111 whether members are static.
2113 2002-08-16 Martin Baulig <martin@gnome.org>
2115 * decl.cs (DeclSpace.Define): Splitted this in Define and
2116 DefineMembers. DefineMembers is called first and initializes the
2119 * rootcontext.cs (RootContext.DefineMembers): New function. Calls
2120 DefineMembers() on all our DeclSpaces.
2122 * class.cs (TypeContainer.Define): Moved all code to DefineMembers(),
2123 but call DefineMembers() on all nested interfaces. We call their
2124 Define() in our new Define() function.
2126 * interface.cs (Interface): Implement IMemberContainer.
2127 (Interface.Define): Moved all code except the attribute stuf to
2129 (Interface.DefineMembers): Initialize the member cache.
2131 * typemanager.cs (IMemberFinder): Removed this interface, we don't
2132 need this anymore since we can use MemberCache.FindMembers directly.
2134 2002-08-19 Martin Baulig <martin@gnome.org>
2136 * typemanager.cs (MemberCache): When creating the cache for an
2137 interface type, add all inherited members.
2138 (TypeManager.MemberLookup_FindMembers): Changed `ref bool searching'
2139 to `out bool used_cache' and documented it.
2140 (TypeManager.MemberLookup): If we already used the cache in the first
2141 iteration, we don't need to do the interfaces check.
2143 2002-08-19 Martin Baulig <martin@gnome.org>
2145 * decl.cs (DeclSpace.FindMembers): New abstract method. Moved this
2146 here from IMemberFinder and don't implement this interface anymore.
2147 (DeclSpace.MemberCache): Moved here from IMemberFinder.
2149 * typemanager.cs (IMemberFinder): This interface is now only used by
2150 classes which actually support the member cache.
2151 (TypeManager.builder_to_member_finder): Renamed to builder_to_declspace
2152 since we only put DeclSpaces into this Hashtable.
2153 (MemberLookup_FindMembers): Use `builder_to_declspace' if the type is
2154 a dynamic type and TypeHandle.GetTypeHandle() otherwise.
2156 2002-08-16 Martin Baulig <martin@gnome.org>
2158 * typemanager.cs (ICachingMemberFinder): Removed.
2159 (IMemberFinder.MemberCache): New property.
2160 (TypeManager.FindMembers): Merged this with RealFindMembers().
2161 This function will never be called from TypeManager.MemberLookup()
2162 so we can't use the cache here, just the IMemberFinder.
2163 (TypeManager.MemberLookup_FindMembers): Check whether the
2164 IMemberFinder has a MemberCache and call the cache's FindMembers
2166 (MemberCache): Rewrote larger parts of this yet another time and
2167 cleaned it up a bit.
2169 2002-08-15 Miguel de Icaza <miguel@ximian.com>
2171 * driver.cs (LoadArgs): Support quoting.
2173 (Usage): Show the CSC-like command line arguments.
2175 Improved a few error messages.
2177 2002-08-15 Martin Baulig <martin@gnome.org>
2179 * typemanager.cs (IMemberContainer.Type): New property.
2180 (IMemberContainer.IsInterface): New property.
2182 The following changes are conditional to BROKEN_RUNTIME, which is
2183 defined at the top of the file.
2185 * typemanager.cs (MemberCache.MemberCache): Don't add the base
2186 class'es members, but add all members from TypeHandle.ObjectType
2187 if we're an interface.
2188 (MemberCache.AddMembers): Set the Declared flag if member.DeclaringType
2189 is the current type.
2190 (MemberCache.CacheEntry.Container): Removed this field.
2191 (TypeHandle.GetMembers): Include inherited members.
2193 2002-08-14 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2195 * typemanager.cs: fixed compilation and added a comment on a field that
2198 2002-08-15 Martin Baulig <martin@gnome.org>
2200 * class.cs (ConstructorInitializer.Resolve): In the
2201 Expression.MemberLookup call, use the queried_type as
2204 * typemanager.cs (IMemberContainer.GetMembers): Removed the `bool
2205 declared' attribute, it's always true.
2206 (IMemberContainer.Parent, IMemberContainer.Name): New properties.
2207 (TypeManager.MemberLookup_FindMembers): [FIXME FIXME FIXME] Added
2208 temporary wrapper for FindMembers which tells MemberLookup whether
2209 members from the base classes are included in the return value.
2210 This will go away soon.
2211 (TypeManager.MemberLookup): Use this temporary hack here; once the
2212 new MemberCache is completed, we don't need to do the DeclaredOnly
2213 looping here anymore since the MemberCache will take care of this.
2214 (TypeManager.IsSubclassOrNestedChildOf): Allow `type == parent'.
2215 (MemberCache): When creating the MemberCache for a class, get
2216 members from the current class and all its base classes.
2217 (MemberCache.CacheEntry.Container): New field. This is a
2218 temporary hack until the Mono runtime is fixed to distinguish
2219 between ReflectedType and DeclaringType. It allows us to use MCS
2220 with both the MS runtime and the unfixed Mono runtime without
2221 problems and without accecting performance.
2222 (MemberCache.SearchMembers): The DeclaredOnly looping from
2223 TypeManager.MemberLookup is now done here.
2225 2002-08-14 Martin Baulig <martin@gnome.org>
2227 * statement.cs (MyStructInfo.MyStructInfo): Don't call
2228 Type.GetFields on dynamic types but get the fields from the
2229 corresponding TypeContainer.
2230 (MyStructInfo.GetStructInfo): Added check for enum types.
2232 * typemanager.cs (MemberList.IsSynchronized): Implemented.
2233 (MemberList.SyncRoot): Implemented.
2234 (TypeManager.FilterWithClosure): No need to check permissions if
2235 closure_start_type == closure_invocation_type, don't crash if
2236 closure_invocation_type is null.
2238 2002-08-13 Martin Baulig <martin@gnome.org>
2240 Rewrote TypeContainer.FindMembers to use a member cache. This
2241 gives us a speed increase of about 35% for the self-hosting MCS
2242 build and of about 15-20% for the class libs (both on GNU/Linux).
2244 * report.cs (Timer): New class to get enhanced profiling. This
2245 whole class is "TIMER" conditional since it remarkably slows down
2248 * class.cs (MemberList): New class. This is an IList wrapper
2249 which we're now using instead of passing MemberInfo[]'s around to
2250 avoid copying this array unnecessarily.
2251 (IMemberFinder.FindMember): Return a MemberList, not a MemberInfo [].
2252 (ICachingMemberFinder, IMemberContainer): New interface.
2253 (TypeManager.FilterWithClosure): If `criteria' is null, the name
2254 has already been checked, otherwise use it for the name comparision.
2255 (TypeManager.FindMembers): Renamed to RealMemberFinder and
2256 provided wrapper which tries to use ICachingMemberFinder.FindMembers
2257 if possible. Returns a MemberList, not a MemberInfo [].
2258 (TypeHandle): New class, implements IMemberContainer. We create
2259 one instance of this class per type, it contains a MemberCache
2260 which is used to do the member lookups.
2261 (MemberCache): New class. Each instance of this class contains
2262 all members of a type and a name-based hash table.
2263 (MemberCache.FindMembers): This is our new member lookup
2264 function. First, it looks up all members of the requested name in
2265 the hash table. Then, it walks this list and sorts out all
2266 applicable members and returns them.
2268 2002-08-13 Martin Baulig <martin@gnome.org>
2270 In addition to a nice code cleanup, this gives us a performance
2271 increase of about 1.4% on GNU/Linux - not much, but it's already
2272 half a second for the self-hosting MCS compilation.
2274 * typemanager.cs (IMemberFinder): New interface. It is used by
2275 TypeManager.FindMembers to call FindMembers on a TypeContainer,
2276 Enum, Delegate or Interface.
2277 (TypeManager.finder_to_member_finder): New PtrHashtable.
2278 (TypeManager.finder_to_container): Removed.
2279 (TypeManager.finder_to_delegate): Removed.
2280 (TypeManager.finder_to_interface): Removed.
2281 (TypeManager.finder_to_enum): Removed.
2283 * interface.cs (Interface): Implement IMemberFinder.
2285 * delegate.cs (Delegate): Implement IMemberFinder.
2287 * enum.cs (Enum): Implement IMemberFinder.
2289 * class.cs (TypeContainer): Implement IMemberFinder.
2291 2002-08-12 Martin Baulig <martin@gnome.org>
2293 * ecore.cs (TypeExpr.DoResolveType): Mark this as virtual.
2295 2002-08-12 Martin Baulig <martin@gnome.org>
2297 * ecore.cs (ITypeExpression): New interface for expressions which
2299 (TypeExpression): Renamed to TypeLookupExpression.
2300 (Expression.DoResolve): If we're doing a types-only lookup, the
2301 expression must implement the ITypeExpression interface and we
2302 call DoResolveType() on it.
2303 (SimpleName): Implement the new ITypeExpression interface.
2304 (SimpleName.SimpleNameResolve): Removed the ec.OnlyLookupTypes
2305 hack, the situation that we're only looking up types can't happen
2306 anymore when this method is called. Moved the type lookup code to
2307 DoResolveType() and call it.
2308 (SimpleName.DoResolveType): This ITypeExpression interface method
2309 is now doing the types-only lookup.
2310 (TypeExpr, TypeLookupExpression): Implement ITypeExpression.
2311 (ResolveFlags): Added MaskExprClass.
2313 * expression.cs (MemberAccess): Implement the ITypeExpression
2315 (MemberAccess.DoResolve): Added support for a types-only lookup
2316 when we're called via ITypeExpression.DoResolveType().
2317 (ComposedCast): Implement the ITypeExpression interface.
2319 * codegen.cs (EmitContext.OnlyLookupTypes): Removed. Call
2320 Expression.Resolve() with ResolveFlags.Type instead.
2322 2002-08-12 Martin Baulig <martin@gnome.org>
2324 * interface.cs (Interface.Define): Apply attributes.
2326 * attribute.cs (Attribute.ApplyAttributes): Added support for
2327 interface attributes.
2329 2002-08-11 Martin Baulig <martin@gnome.org>
2331 * statement.cs (Block.Emit): Only check the "this" variable if we
2332 do not always throw an exception.
2334 * ecore.cs (PropertyExpr.DoResolveLValue): Implemented, check
2335 whether the property has a set accessor.
2337 2002-08-11 Martin Baulig <martin@gnome.org>
2339 Added control flow analysis support for structs.
2341 * ecore.cs (ResolveFlags): Added `DisableFlowAnalysis' to resolve
2342 with control flow analysis turned off.
2343 (IVariable): New interface.
2344 (SimpleName.SimpleNameResolve): If MemberAccess.ResolveMemberAccess
2345 returns an IMemberExpr, call DoResolve/DoResolveLValue on it.
2346 (FieldExpr.DoResolve): Resolve the instance expression with flow
2347 analysis turned off and do the definite assignment check after the
2348 resolving when we know what the expression will resolve to.
2350 * expression.cs (LocalVariableReference, ParameterReference):
2351 Implement the new IVariable interface, only call the flow analysis
2352 code if ec.DoFlowAnalysis is true.
2353 (This): Added constructor which takes a Block argument. Implement
2354 the new IVariable interface.
2355 (MemberAccess.DoResolve, MemberAccess.DoResolveLValue): Call
2356 DoResolve/DoResolveLValue on the result of ResolveMemberLookup().
2357 This does the definite assignment checks for struct members.
2359 * class.cs (Constructor.Emit): If this is a non-static `struct'
2360 constructor which doesn't have any initializer, call
2361 Block.AddThisVariable() to tell the flow analysis code that all
2362 struct elements must be initialized before control returns from
2365 * statement.cs (MyStructInfo): New public class.
2366 (UsageVector.this [VariableInfo vi]): Added `int field_idx'
2367 argument to this indexer. If non-zero, check an individual struct
2368 member, not the whole struct.
2369 (FlowBranching.CheckOutParameters): Check struct members.
2370 (FlowBranching.IsVariableAssigned, SetVariableAssigned): Added
2371 overloaded versions of these methods which take an additional
2372 `int field_idx' argument to check struct members.
2373 (FlowBranching.IsParameterAssigned, SetParameterAssigned): Added
2374 overloaded versions of these methods which take an additional
2375 `string field_name' argument to check struct member.s
2376 (VariableInfo): Implement the IVariable interface.
2377 (VariableInfo.StructInfo): New public property. Returns the
2378 MyStructInfo instance of the variable if it's a struct or null.
2379 (Block.AddThisVariable): New public method. This is called from
2380 Constructor.Emit() for non-static `struct' constructor which do
2381 not have any initializer. It creates a special variable for the
2382 "this" instance variable which will be checked by the flow
2383 analysis code to ensure that all of the struct's fields are
2384 initialized before control returns from the constructor.
2385 (UsageVector): Added support for struct members. If a
2386 variable/parameter is a struct with N members, we reserve a slot
2387 in the usage vector for each member. A struct is considered fully
2388 initialized if either the struct itself (slot 0) or all its
2389 members are initialized.
2391 2002-08-08 Martin Baulig <martin@gnome.org>
2393 * driver.cs (Driver.MainDriver): Only report an error CS5001
2394 if there were no compilation errors.
2396 * codegen.cs (EmitContext.EmitContext): Use the DeclSpace's
2397 `UnsafeContext' property to determine whether the parent is in
2398 unsafe context rather than checking the parent's ModFlags:
2399 classes nested in an unsafe class are unsafe as well.
2401 2002-08-08 Martin Baulig <martin@gnome.org>
2403 * statement.cs (UsageVector.MergeChildren): Distinguish between
2404 `Breaks' and `Returns' everywhere, don't set `Breaks' anymore if
2405 we return. Added test17() and test18() to test-154.cs.
2407 2002-08-08 Martin Baulig <martin@gnome.org>
2409 * typemanager.cs (TypeManager.FilterWithClosure): If we have
2410 Family access, make sure the invoking type isn't a subclass of the
2411 queried type (that'd be a CS1540).
2413 * ecore.cs (Expression.MemberLookup): Added overloaded version of
2414 this method which takes an additional `Type invocation_type'.
2416 * expression.cs (BaseAccess.DoResolve): Use the base type as
2417 invocation and query type.
2418 (MemberAccess.DoResolve): If the lookup failed and we're about to
2419 report a CS0122, try a lookup with the ec.ContainerType - if this
2420 succeeds, we must report a CS1540.
2422 2002-08-08 Martin Baulig <martin@gnome.org>
2424 * ecore.cs (IMemberExpr): Added `bool IsInstance' property.
2425 (MethodGroupExpr): Implement the IMemberExpr interface.
2427 * expression (MemberAccess.ResolveMemberAccess): No need to have
2428 any special code for MethodGroupExprs anymore, they're now
2431 2002-08-08 Martin Baulig <martin@gnome.org>
2433 * typemanager.cs (TypeManager.FilterWithClosure): Check Assembly,
2434 Family, FamANDAssem and FamORAssem permissions.
2435 (TypeManager.IsSubclassOrNestedChildOf): New public method.
2437 2002-08-08 Martin Baulig <martin@gnome.org>
2439 * statement.cs (FlowBranchingType): Added LOOP_BLOCK.
2440 (UsageVector.MergeChildren): `break' breaks unless we're in a switch
2443 Thu Aug 8 10:28:07 CEST 2002 Paolo Molaro <lupus@ximian.com>
2445 * driver.cs: implemented /resource option to embed managed resources.
2447 2002-08-07 Martin Baulig <martin@gnome.org>
2449 * class.cs (FieldBase.Initializer): Renamed to `init' and made private.
2450 (FieldBase.HasFieldInitializer): New public property.
2451 (FieldBase.GetInitializerExpression): New public method. Resolves and
2452 returns the field initializer and makes sure it is only resolved once.
2453 (TypeContainer.EmitFieldInitializers): Call
2454 FieldBase.GetInitializerExpression to get the initializer, this ensures
2455 that it isn't resolved multiple times.
2457 * codegen.cs (EmitContext): Added `bool IsFieldInitialier'. This tells
2458 the resolving process (SimpleName/MemberLookup) that we're currently
2459 emitting a field initializer (which must not access any instance members,
2460 this is an error CS0236).
2462 * ecore.cs (SimpleName.Error_ObjectRefRequired): Added EmitContext
2463 argument, if the `IsFieldInitializer' flag is set, we must report and
2464 error CS0236 and not an error CS0120.
2466 2002-08-07 Martin Baulig <martin@gnome.org>
2468 * ecore.cs (IMemberExpr): New public interface.
2469 (FieldExpr, PropertyExpr, EventExpr): Implement IMemberExpr.
2470 (SimpleName.SimpleNameResolve): Call MemberAccess.ResolveMemberAccess
2471 if the expression is an IMemberExpr.
2473 * expression.cs (MemberAccess.ResolveMemberAccess): Allow `left'
2474 to be null, implicitly default to `this' if we're non-static in
2475 this case. Simplified the code a lot by using the new IMemberExpr
2476 interface. Also fixed bug #28176 here.
2478 2002-08-06 Martin Baulig <martin@gnome.org>
2480 * cs-parser.jay (SimpleLookup): Removed. We need to create
2481 ParameterReferences during semantic analysis so that we can do a
2482 type-only search when resolving Cast, TypeOf and SizeOf.
2483 (block): Pass the `current_local_parameters' to the Block's
2486 * class.cs (ConstructorInitializer): Added `Parameters parameters'

2495 `Parameters parameters' argument.
2496 (Block.Parameters): New public property.
2498 * support.cs (InternalParameters.Parameters): Renamed `parameters'
2499 to `Parameters' and made it public readonly.

2503 * ecore.cs (Expression.Warning): Made this public as well.
2505 * report.cs (Report.Debug): Print the contents of collections.
2507 2002-08-06 Martin Baulig <martin@gnome.org>
2509 * ecore.cs (Expression.ResolveFlags): New [Flags] enum. This is
2510 used to tell Resolve() which kinds of expressions it may return.
2511 (Expression.Resolve): Added overloaded version of this method which
2512 takes a `ResolveFlags flags' argument. This can be used to tell
2513 Resolve() which kinds of expressions it may return. Reports a
2515 (Expression.ResolveWithSimpleName): Removed, use Resolve() with
2516 ResolveFlags.SimpleName.
2517 (Expression.Error118): Added overloaded version of this method which
2518 takes a `ResolveFlags flags' argument. It uses the flags to determine
2519 which kinds of expressions are allowed.
2521 * expression.cs (Argument.ResolveMethodGroup): New public method.
2522 Resolves an argument, but allows a MethodGroup to be returned.
2523 This is used when invoking a delegate.
2525 * TODO: Updated a bit.
2527 2002-08-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2529 Fixed compilation with csc.
2531 * ecore.cs: Expression.Error made public. Is this correct? Should
2532 Warning be made public too?
2534 * expression.cs: use ea.Location instead of ea.loc.
2535 [FIXME: Filed as bug #28607: MCS must report these errors.]
2537 2002-08-06 Martin Baulig <martin@gnome.org>
2539 * ecore.cs (Expression.loc): Moved the location here instead of
2540 duplicating it in all derived classes.
2541 (Expression.Location): New public property.
2542 (Expression.Error, Expression.Warning): Made them non-static and
2543 removed the location argument.
2544 (Expression.Warning): Added overloaded version which takes an
2545 `int level' argument.
2546 (Expression.Error118): Make this non-static and removed the
2547 expression and location arguments.
2548 (TypeExpr): Added location argument to the constructor.
2550 * expression.cs (StaticCallExpr): Added location argument to
2552 (Indirection, PointerArithmetic): Likewise.
2553 (CheckedExpr, UnCheckedExpr): Likewise.
2554 (ArrayAccess, IndexerAccess, UserCast, ArrayPtr): Likewise.
2555 (StringPtr): Likewise.
2558 2002-08-05 Martin Baulig <martin@gnome.org>
2560 * expression.cs (BaseAccess.DoResolve): Actually report errors.
2562 * assign.cs (Assign.DoResolve): Check whether the source
2563 expression is a value or variable.
2565 * statement.cs (Try.Resolve): Set ec.InTry/InCatch/InFinally
2566 while resolving the corresponding blocks.
2568 * interface.cs (Interface.GetInterfaceTypeByName): Actually report
2569 an error, don't silently return null.

2572 and distinguish between CS0128 and CS0136.
2573 (Block.DoResolve): Report all unused labels (warning CS0164).
2574 (LabeledStatement): Pass the location to the constructor.
2575 (LabeledStatement.HasBeenReferenced): New property.
2576 (LabeledStatement.Resolve): Set it to true here.
2578 * statement.cs (Return.Emit): Return success even after reporting
2579 a type mismatch error (CS0126 or CS0127), this is what csc does and
2580 it avoids confusing the users with any consecutive errors.
2582 2002-08-05 Martin Baulig <martin@gnome.org>
2584 * enum.cs (Enum.LookupEnumValue): Catch circular definitions.
2586 * const.cs (Const.LookupConstantValue): Catch circular definitions.
2588 * expression.cs (MemberAccess.DoResolve): Silently return if an
2589 error has already been reported.

2592 error has already been reported.
2594 2002-08-05 Martin Baulig <martin@gnome.org>
2596 * statement.cs (UsageVector): Only initialize the `parameters'
2597 vector if we actually have any "out" parameters.
2599 2002-08-05 Martin Baulig <martin@gnome.org>
2601 * expression.cs (Binary.ResolveOperator): When combining delegates,
2602 they must have the same type.
2604 2002-08-05 Martin Baulig <martin@gnome.org>
2606 * typemanager.cs (TypeManager.GetArgumentTypes): Don't call
2607 PropertyInfo.GetIndexParameters() on dynamic types, this doesn't
2608 work with the ms runtime and we also don't need it: if we're a
2609 PropertyBuilder and not in the `indexer_arguments' hash, then we
2610 are a property and not an indexer.
2612 * class.cs (TypeContainer.AsAccessible): Use Type.IsArray,
2613 Type.IsPointer and Type.IsByRef instead of Type.HasElementType
2614 since the latter one doesn't work with the ms runtime.
2616 2002-08-03 Martin Baulig <martin@gnome.org>
2618 Fixed bugs #27998 and #22735.
2620 * class.cs (Method.IsOperator): New public field.
2621 (Method.CheckBase): Report CS0111 if there's already a method
2622 with the same parameters in the current class. Report CS0508 when
2623 attempting to change the return type of an inherited method.
2624 (MethodData.Emit): Report CS0179 if a method doesn't have a body
2625 and it's not marked abstract or extern.
2626 (PropertyBase): New abstract base class for Property and Indexer.
2627 (PropertyBase.CheckBase): Moved here from Property and made it work
2629 (PropertyBase.Emit): Moved here from Property.Emit, Indexer.Emit is
2630 the same so we can reuse it there.
2631 (Property, Indexer): Derive from PropertyBase.
2632 (MethodSignature.inheritable_property_signature_filter): New delegate
2633 to find properties and indexers.
2635 * decl.cs (MemberCore.CheckMethodAgainstBase): Added `string name'
2636 argument and improved error reporting.
2638 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): Renamed to
2639 EmptyReadOnlyParameters and made it a property.
2641 * typemanager.cs (TypeManager.GetArgumentTypes): Added overloaded
2642 version of this method which takes a `PropertyInfo indexer'.
2643 (TypeManager.RegisterIndexer): New method.
2645 * class.cs: Added myself as author of this file :-)
2647 2002-08-03 Gonzalo Paniagua Javier <gonzalo@ximian.com>

2656 * class.cs (TypeContainer.GetClassBases): Check whether base types
2657 are at least as accessible than the current type.
2658 (TypeContainer.AsAccessible): Implemented and made non-static.
2659 (MemberBase.CheckParameters): Report errors if the accessibility
2662 * delegate.cs (Delegate.Delegate): The default visibility is
2663 internal for top-level types and private for nested types.
2664 (Delegate.Define): Report errors if the accessibility checks fail.
2666 * enum.cs (Enum.Enum): The default visibility is internal for
2667 top-level types and private for nested types.
2668 (Enum.DefineType): Compute the correct visibility.
2670 * modifiers.cs (Modifiers.TypeAttr): Added a version of this
2671 function which takes a `bool is_toplevel' instead of a TypeContainer.
2673 * typemanager.cs (TypeManager.IsBuiltinType): `void' is also a
2676 2002-08-02 Martin Baulig <martin@gnome.org>
2678 * expression.cs (LocalVariableReferenc): Added constructor which
2679 takes additional `VariableInfo vi' and `bool is_readonly' arguments.
2680 (LocalVariableReference.IsReadOnly): New property.
2681 (LocalVariableReference.DoResolveLValue): Report a CS1604 if the
2682 variable is readonly, use our own readonly flag to do this; you can
2683 use the new constructor to get a writable reference to a read-only
2686 * cs-parser.jay (foreach_statement, using_statement): Get a writable
2687 reference to the local variable.
2689 2002-08-01 Miguel de Icaza <miguel@ximian.com>

2706 * class.cs (TypeContainer.Define): Define all nested interfaces here.
2707 Fixes bug #28407, added test-155.cs.
2709 2002-08-01 Martin Baulig <martin@gnome.org>

2823 is a flag which specifies that it's either ref or out.
2824 (Parameter.GetParameterInfo (DeclSpace, int, out bool)): Changed
2825 the out parameter to `out Parameter.Modifier mod', also set the
2826 Parameter.Modifier.ISBYREF flag on it if it's either ref or out.

2899 (MethodData.GetMethodFlags): Moved here from MemberBase.
2900 (MethodData.ApplyAttributes): Likewise.
2901 (MethodData.ApplyObsoleteAttribute): Likewise.
2902 (MethodData.ApplyConditionalAttribute): Likewise.
2903 (MethodData.ApplyDllImportAttribute): Likewise.
2904 (MethodData.CheckAbstractAndExternal): Likewise.
2905 (MethodData.Define): Formerly knows as MemberBase.DefineMethod().
2906 (MethodData.Emit): Formerly known as Method.Emit().
2907 (MemberBase): Moved everything which was specific to a single
2908 accessor/method to MethodData.
2909 (Method): Create a new MethodData and call Define() and Emit() on it.
2910 (Property, Indexer, Event): Create a new MethodData objects for each
2911 accessor and call Define() and Emit() on them.
2913 2002-07-25 Martin Baulig <martin@gnome.org>
2915 Made MethodCore derive from MemberBase to reuse the code from there.
2916 MemberBase now also checks for attributes.

2942 ensure that abstract and external accessors don't declare a body.
2944 * attribute.cs (Attribute.GetValidPieces): Make this actually work:
2945 `System.Attribute.GetCustomAttributes (attr.Type)' does a recursive
2946 lookup in the attribute's parent classes, so we need to abort as soon
2947 as we found the first match.
2948 (Attribute.Obsolete_GetObsoleteMessage): Return the empty string if
2949 the attribute has no arguments.
2951 * typemanager.cs (TypeManager.AddMethod): Now takes a MemberBase instead

2981 if we're overriding a virtual function, set the new private variable
2982 `parent_method'; call the new TypeManager.AddMethod().
2984 * typemanager.cs (TypeManager.AddMethod): New static method. Stores
2985 the MethodBuilder and the Method in a PtrHashtable.
2986 (TypeManager.builder_to_method): Added for this purpose.
2987 (TypeManager.MethodFlags): Added IsObsoleteError.
2988 (TypeManager.GetMethodFlags): Added `Location loc' argument. Lookup
2989 Obsolete and Conditional arguments in MethodBuilders. If we discover
2990 an Obsolete attribute, emit an appropriate warning 618 / error 619 with
2991 the message from the attribute.
2993 2002-07-24 Martin Baulig <martin@gnome.org>
2995 * cs-tokenizer.cs: Eat up trailing whitespaces and one-line comments in
2996 preprocessor directives, ensure that the argument to #define/#undef is
2997 exactly one identifier and that it's actually an identifier.
2999 Some weeks ago I did a `#define DEBUG 1' myself and wondered why this
3002 2002-07-24 Martin Baulig <martin@gnome.org>
3004 * statement.cs (Foreach.ForeachHelperMethods): Added `Type element_type',
3005 initialize it to TypeManager.object_type in the constructor.
3006 (Foreach.GetEnumeratorFilter): Set `hm.element_type' to the return type
3007 of the `hm.get_current' method if we're using the collection pattern.
3008 (Foreach.EmitCollectionForeach): Use `hm.element_type' as the source type
3009 for the explicit conversion to make it work when we're using the collection
3010 pattern and the `Current' property has a different return type than `object'.
3013 2002-07-24 Martin Baulig <martin@gnome.org>
3015 * delegate.cs (Delegate.VerifyMethod): Simply return null if the method
3016 does not match, but don't report any errors. This method is called in
3017 order for all methods in a MethodGroupExpr until a matching method is
3018 found, so we don't want to bail out if the first method doesn't match.
3019 (NewDelegate.DoResolve): If none of the methods in the MethodGroupExpr
3020 matches, report the 123. Fixes #28070.
3022 2002-07-24 Martin Baulig <martin@gnome.org>
3024 * expression.cs (ArrayAccess.EmitStoreOpcode): Moved the
3025 TypeManager.TypeToCoreType() to the top of the method so the
3026 following equality checks will work. Fixes #28107.
3028 2002-07-24 Martin Baulig <martin@gnome.org>
3030 * cfold.cs (ConstantFold.DoConstantNumericPromotions): "If either
3031 operand is of type uint, and the other operand is of type sbyte,
3032 short or int, the operands are converted to type long." -
3033 Actually do what this comment already told us. Fixes bug #28106,
3036 2002-07-24 Martin Baulig <martin@gnome.org>
3038 * class.cs (MethodBase): New abstract class. This is now a base
3039 class for Property, Indexer and Event to avoid some code duplication
3040 in their Define() and DefineMethods() methods.
3041 (MethodBase.DoDefine, MethodBase.DefineAccessor): Provide virtual
3042 generic methods for Define() and DefineMethods().
3043 (FieldBase): Derive from MemberBase, not MemberCore.
3044 (Property): Derive from MemberBase, not MemberCore.
3045 (Property.DefineMethod): Moved all the code from this method to the
3046 new MethodBase.DefineAccessor(), just call it with appropriate
3048 (Property.Define): Call the new Property.DoDefine(), this does some
3049 sanity checks and we don't need to duplicate the code everywhere.
3050 (Event): Derive from MemberBase, not MemberCore.
3051 (Event.Define): Use the new MethodBase.DefineAccessor() to define the
3052 accessors, this will also make them work with interface events.
3053 (Indexer): Derive from MemberBase, not MemberCore.
3054 (Indexer.DefineMethod): Removed, call MethodBase.DefineAccessor() insstead.
3055 (Indexer.Define): Use the new MethodBase functions.
3057 * interface.cs (InterfaceEvent.InterfaceEvent): Added `Location loc'
3058 argument to the constructor.
3059 (Interface.FindMembers): Added support for interface events.
3060 (Interface.PopluateEvent): Implemented.
3062 Added test-149.cs for this. This also fixes bugs #26067 and #24256.
3064 2002-07-22 Miguel de Icaza <miguel@ximian.com>
3066 * class.cs (TypeContainer.AddMethod): Adding methods do not use IsValid,
3067 but this is required to check for a method name being the same as
3068 the containing class.
3072 2002-07-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3074 * interface.cs: initialize variable.
3076 2002-07-23 Martin Baulig <martin@gnome.org>
3078 Implemented the IndexerName attribute in interfaces.
3080 * class.cs (TypeContainer.DefineIndexers): Don't set the indexer
3081 name if this is an explicit interface implementation.
3082 (Indexer.InterfaceIndexerName): New public variable. If we're
3083 implementing an interface indexer, this is the IndexerName in that
3084 interface. Otherwise, it's the IndexerName.
3085 (Indexer.DefineMethod): If we're implementing interface indexer,
3086 set InterfaceIndexerName. Use the new Pending.IsInterfaceIndexer
3087 and Pending.ImplementIndexer methods.
3088 (Indexer.Define): Also define the PropertyBuilder if we're
3089 implementing an interface indexer and this is neither an explicit
3090 interface implementation nor do the IndexerName match the one in
3093 * pending.cs (TypeAndMethods): Added `MethodInfo [] need_proxy'.
3094 If a method is defined here, then we always need to create a proxy
3095 for it. This is used when implementing interface indexers.
3096 (Pending.IsInterfaceIndexer): New public method.
3097 (Pending.ImplementIndexer): New public method.
3098 (Pending.InterfaceMethod): Added `MethodInfo need_proxy' argument.
3099 This is used when implementing interface indexers to define a proxy
3101 (Pending.VerifyPendingMethods): Look in the `need_proxy' array and
3102 define a proxy if necessary.
3104 * interface.cs (Interface.IndexerName): New public variable.
3105 (Interface.PopulateIndexer): Set the IndexerName.
3106 (Interface.DefineIndexers): New private method. Populate all the
3107 indexers and make sure their IndexerNames match.
3109 * typemanager.cs (IndexerPropertyName): Added support for interface
3112 2002-07-22 Martin Baulig <martin@gnome.org>
3114 * codegen.cs (EmitContext.HasReturnLabel): New public variable.
3115 (EmitContext.EmitTopBlock): Always mark the ReturnLabel and emit a
3116 ret if HasReturnLabel.
3117 (EmitContext.TryCatchLevel, LoopBeginTryCatchLevel): New public
3120 * statement.cs (Do.Emit, While.Emit, For.Emit, Foreach.Emit): Save
3121 and set the ec.LoopBeginTryCatchLevel.
3122 (Try.Emit): Increment the ec.TryCatchLevel while emitting the block.
3123 (Continue.Emit): If the ec.LoopBeginTryCatchLevel is smaller than
3124 the current ec.TryCatchLevel, the branch goes out of an exception
3125 block. In this case, we need to use Leave and not Br.
3127 2002-07-22 Martin Baulig <martin@gnome.org>
3129 * statement.cs (Try.Emit): Emit an explicit ret after the end of the
3130 block unless the block does not always return or it is contained in
3131 another try { ... } catch { ... } block. Fixes bug #26506.
3132 Added verify-1.cs to the test suite.
3134 2002-07-22 Martin Baulig <martin@gnome.org>
3136 * statement.cs (Switch.TableSwitchEmit): If we don't have a default,
3137 then we do not always return. Fixes bug #24985.
3139 2002-07-22 Martin Baulig <martin@gnome.org>
3141 * expression.cs (Invocation.OverloadedResolve): Do the BetterFunction()
3142 lookup on a per-class level; ie. walk up the class hierarchy until we
3143 found at least one applicable method, then choose the best among them.
3144 Fixes bug #24463 and test-29.cs.
3146 2002-07-22 Martin Baulig <martin@gnome.org>
3148 * typemanager.cs (TypeManager.ArrayContainsMethod): Don't check the
3149 return types of the methods. The return type is not part of the
3150 signature and we must not check it to make the `new' modifier work.
3151 Fixes bug #27999, also added test-147.cs.
3152 (TypeManager.TypeToCoreType): Added TypeManager.type_type.
3154 * expression.cs (Invocation.DoResolve): Call TypeManager.TypeToCoreType()
3155 on the method's return type.
3157 2002-07-21 Martin Baulig <martin@gnome.org>
3159 * assign.cs: Make this work if the rightmost source is a constant and
3160 we need to do an implicit type conversion. Also adding a few more tests
3161 to test-38.cs which should have caught this.
3163 * makefile.gnu: Disable debugging, there's already the mcs-mono2.exe
3164 target in the makefile for this. The makefile.gnu is primarily intended
3165 for end-users who don't want to debug the compiler.
3167 2002-07-21 Martin Baulig <martin@gnome.org>
3169 * assign.cs: Improved the Assign class so it can now handle embedded
3170 assignments (X = Y = Z = something). As a side-effect this'll now also
3171 consume less local variables. test-38.cs now passes with MCS, added
3172 a few new test cases to that test.
3174 2002-07-20 Martin Baulig <martin@gnome.org>
3176 * expression.cs (Binary.EmitBranchable): Emit correct unsigned branch
3177 instructions. Fixes bug #27977, also added test-146.cs.
3179 2002-07-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3181 * cs-tokenizer.cs: fixed getHex ().
3183 2002-07-19 Martin Baulig <martin@gnome.org>
3185 * expression.cs (Invocation.EmitParams): Use TypeManager.LookupType(),
3186 not Type.GetType() to lookup the array type. This is needed when
3187 we're constructing an array of a user-defined type.
3188 (ArrayAccess.EmitDynamicInitializers): Only emit the Ldelema for
3189 single-dimensional arrays, but also for single-dimensial arrays of
3192 2002-07-19 Martin Baulig <martin@gnome.org>
3194 * expression.cs (New.DoEmit): Create a new LocalTemporary each time
3195 this function is called, it's not allowed to share LocalBuilders
3198 2002-07-19 Martin Baulig <martin@gnome.org>
3200 * expression.cs (Argument.Resolve): Report an error 118 when trying
3201 to pass a type as argument.
3203 2002-07-18 Martin Baulig <martin@gnome.org>
3205 * ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
3206 Conv_R_Un for the signed `long' type.
3208 2002-07-15 Miguel de Icaza <miguel@ximian.com>
3210 * expression.cs (MemberAccess.DoResolve): Do not reuse the field
3211 `expr' for the temporary result, as that will fail if we do
3212 multiple resolves on the same expression.
3214 2002-07-05 Miguel de Icaza <miguel@ximian.com>
3216 * ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
3217 ec.TypeContainer for looking up aliases.
3219 * class.cs (TypeContainer): Remove LookupAlias from here.
3221 * decl.cs (DeclSpace); Move here.
3223 2002-07-01 Miguel de Icaza <miguel@ximian.com>
3225 * class.cs (FindMembers): Only call filter if the constructor
3226 bulider is not null.
3228 Also handle delegates in `NestedTypes' now. Now we will perform
3229 type lookups using the standard resolution process. This also
3232 * decl.cs (DeclSpace.ResolveType): New type resolution routine.
3233 This uses Expressions (the limited kind that can be parsed by the
3234 tree) instead of strings.
3236 * expression.cs (ComposedCast.ToString): Implement, used to flag
3237 errors since now we have to render expressions.
3239 (ArrayCreation): Kill FormElementType. Use ComposedCasts in
3242 * ecore.cs (SimpleName.ToString): ditto.
3244 * cs-parser.jay: Instead of using strings to assemble types, use
3245 Expressions to assemble the type (using SimpleName, ComposedCast,
3246 MemberAccess). This should fix the type lookups in declarations,
3247 because we were using a different code path for this.
3249 * statement.cs (Block.Resolve): Continue processing statements
3250 even when there is an error.
3252 2002-07-17 Miguel de Icaza <miguel@ximian.com>
3254 * class.cs (Event.Define): Also remove the `remove' method from
3255 the list of pending items.
3257 * expression.cs (ParameterReference): Use ldarg.N (0..3) to
3258 generate more compact code.
3260 2002-07-17 Martin Baulig <martin@gnome.org>
3262 * const.cs (Const.LookupConstantValue): Add support for constant
3263 `unchecked' and `checked' expressions.
3264 Also adding test case test-140.cs for this.
3266 2002-07-17 Martin Baulig <martin@gnome.org>
3268 * statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
3269 check whether mi.ReturnType implements the IEnumerator interface; the
3270 `==' and the IsAssignableFrom() will fail in this situation.
3272 2002-07-16 Ravi Pratap <ravi@ximian.com>
3274 * ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix
3277 2002-07-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3279 * expression.cs: fixed bug #27811.
3281 2002-07-14 Miguel de Icaza <miguel@ximian.com>
3283 * expression.cs (ParameterReference.AddressOf): Patch from Paolo
3284 Molaro: when we are a ref, the value already contains a pointer
3285 value, do not take the address of it.
3287 2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
3288 * removed mb-parser.jay and mb-tokenizer.cs
3290 Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
3292 * expression.cs: check against the building corlib void type.
3294 Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
3296 * ecore.cs: fix for valuetype static readonly fields: when
3297 initializing them, we need their address, not the address of a copy.
3299 Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
3301 * typemanager.cs: register also enum_type in corlib.
3303 Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
3305 * class.cs: allow calling this (but not base) initializers in structs.
3307 Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
3309 * ecore.cs: make sure we compare against the building base types
3312 Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
3314 * typemanager.cs: fix TypeToCoreType() to handle void and object
3315 (corlib gets no more typerefs after this change).
3317 2002-07-12 Miguel de Icaza <miguel@ximian.com>
3319 * expression.cs (ArrayCreation.EmitArrayArguments): use
3320 Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
3322 (ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
3323 Conv_Ovf_I_Un for the array arguments. Even if C# allows longs as
3324 array indexes, the runtime actually forbids them.
3326 * ecore.cs (ExpressionToArrayArgument): Move the conversion code
3327 for array arguments here.
3329 * expression.cs (EmitLoadOpcode): System.Char is a U2, use that
3330 instead of the default for ValueTypes.
3332 (New.DoEmit): Use IsValueType instead of
3333 IsSubclassOf (value_type)
3334 (New.DoResolve): ditto.
3335 (Invocation.EmitCall): ditto.
3337 * assign.cs (Assign): ditto.
3339 * statement.cs (Unsafe): Ok, so I got the semantics wrong.
3340 Statements *are* currently doing part of their resolution during
3343 Expressions do always resolve during resolve, but statements are
3344 only required to propagate resolution to their children.
3346 2002-07-11 Miguel de Icaza <miguel@ximian.com>
3348 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
3350 (LoadAssembly): Do not add the dll if it is already specified
3352 (MainDriver): Add the System directory to the link path at the end,
3353 after all the other -L arguments.
3355 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
3356 wrong opcode for loading bytes and bools (ldelem.i1 instead of
3357 ldelem.u1) and using the opposite for sbytes.
3359 This fixes Digger, and we can finally run it.
3361 * driver.cs (UnixParseOption): Move the option parsing here.
3362 (CSCParseOption): Implement CSC-like parsing of options.
3364 We now support both modes of operation, the old Unix way, and the
3365 new CSC-like way. This should help those who wanted to make cross
3368 The only thing broken is that /r:, /reference: and /lib: are not
3369 implemented, because I want to make those have the same semantics
3370 as the CSC compiler has, and kill once and for all the confussion
3371 around this. Will be doing this tomorrow.
3373 * statement.cs (Unsafe.Resolve): The state is checked during
3374 resolve, not emit, so we have to set the flags for IsUnsfe here.
3376 2002-07-10 Miguel de Icaza <miguel@ximian.com>
3378 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
3379 not catch the Error_ObjectRefRequired in SimpleName (as it is
3380 possible to have a class/instance variable name that later gets
3381 deambiguated), we have to check this here.
3383 2002-07-10 Ravi Pratap <ravi@ximian.com>
3385 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
3386 make static and put into Expression.
3388 (Event.Define): Register the private field of the event with the
3389 TypeManager so that GetFieldFromEvent can get at it.
3391 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
3392 keep track of the private field associated with an event which
3395 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
3398 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
3400 2002-07-10 Miguel de Icaza <miguel@ximian.com>
3402 * expression.cs (Binary.EmitBranchable): this routine emits the
3403 Binary expression in a branchable context. This basically means:
3404 we need to branch somewhere, not just get the value on the stack.
3406 This works together with Statement.EmitBoolExpression.
3408 * statement.cs (Statement.EmitBoolExpression): Use
3411 2002-07-09 Miguel de Icaza <miguel@ximian.com>
3413 * statement.cs (For): Reduce the number of jumps in loops.
3415 (For): Implement loop inversion for the For statement.
3417 (Break): We can be breaking out of a Try/Catch controlled section
3418 (foreach might have an implicit try/catch clause), so we need to
3419 use Leave instead of Br.
3421 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
3422 now). If the instace expression supports IMemoryLocation, we use
3423 the AddressOf method from the IMemoryLocation to extract the
3424 address instead of emitting the instance.
3426 This showed up with `This', as we were emitting the instance
3427 always (Emit) instead of the Address of This. Particularly
3428 interesting when This is a value type, as we dont want the Emit
3429 effect (which was to load the object).
3431 2002-07-08 Miguel de Icaza <miguel@ximian.com>
3433 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
3435 * statement.cs (Checked): Set the CheckedState during the resolve
3436 process too, as the ConvCast operations track the checked state on
3437 the resolve process, and not emit.
3439 * cs-parser.jay (namespace_member_declaration): Flag that we have
3440 found a declaration when we do. This is used to flag error 1529
3442 * driver.cs: Report ok when we display the help only.
3444 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
3446 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
3448 2002-07-04 Miguel de Icaza <miguel@ximian.com>
3450 * cs-tokenizer.cs (define): We also have to track locally the
3451 defines. AllDefines is just used for the Conditional Attribute,
3452 but we also need the local defines for the current source code.
3454 2002-07-03 Miguel de Icaza <miguel@ximian.com>
3456 * statement.cs (While, For, Do): These loops can exit through a
3457 Break statement, use this information to tell whether the
3458 statement is the last piece of code.
3460 (Break): Flag that we break.
3462 * codegen.cs (EmitContexts): New `Breaks' state variable.
3464 2002-07-03 Martin Baulig <martin@gnome.org>
3466 * class.cs (TypeContainer.MethodModifiersValid): Allow override
3467 modifiers in method declarations in structs. Otherwise, you won't
3468 be able to override things like Object.Equals().
3470 2002-07-02 Miguel de Icaza <miguel@ximian.com>
3472 * class.cs (Method, Property, Indexer): Do not allow the public
3473 modifier to be used in explicit interface implementations.
3475 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
3476 override modifiers in method declarations in structs
3478 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
3480 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
3481 integer or real overflow, report an error
3483 2002-07-02 Martin Baulig <martin@gnome.org>
3485 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
3486 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
3487 to tell the runtime about our newly created System.Object and
3488 System.ValueType types.
3490 2002-07-02 Miguel de Icaza <miguel@ximian.com>
3492 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
3493 struct instead of Ldarg/Starg.
3495 2002-07-02 Martin Baulig <martin@gnome.org>
3497 * expression.cs (Indirection.Indirection): Call
3498 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
3500 2002-07-02 Martin Baulig <martin@gnome.org>
3502 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
3503 ValueType, call TypeManager.TypeToCoreType() on it.
3504 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
3505 the OpCodes.Newarr argument.
3507 2002-07-02 Martin Baulig <martin@gnome.org>
3509 * expression.cs (Invocation.EmitCall): When compiling corlib,
3510 replace all calls to the system's System.Array type to calls to
3511 the newly created one.
3513 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
3514 System.Array methods.
3515 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
3516 from the system's System.Array type which must be replaced.
3518 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
3520 * typemanager.cs: load unverifiable_code_ctor so we can build
3521 corlib using the correct type. Avoid using GetTypeCode() with
3523 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
3524 TypeManager.object_type to allow building corlib.
3526 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
3528 * ecore.cs: handle System.Enum separately in LoadFromPtr().
3530 2002-07-01 Martin Baulig <martin@gnome.org>
3532 * class.cs: Make the last change actually work, we need to check
3533 whether `ifaces != null' to avoid a crash.
3535 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
3537 * class.cs: when we build structs without fields that implement
3538 interfaces, we need to add the interfaces separately, since there is
3539 no API to both set the size and add the interfaces at type creation
3542 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
3544 * expression.cs: the dimension arguments to the array constructors
3545 need to be converted if they are a long.
3547 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
3549 * class.cs: don't emit ldarg.0 if there is no parent constructor
3550 (fixes showstopper for corlib).
3552 2002-06-29 Martin Baulig <martin@gnome.org>
3554 MCS now compiles corlib on GNU/Linux :-)
3556 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
3557 ie. check for MethodImplOptions.InternalCall.
3559 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
3560 and TypeManager.attribute_type are null, so we must explicitly check
3561 whether parent is not null to find out whether it's an attribute type.
3562 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
3563 and SetBuilder, not only if the property is neither abstract nor external.
3564 This is necessary to set the MethodImplOptions on the accessor methods.
3565 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
3566 SetBuilder, see Property.Emit().
3568 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
3569 populate "System.Object", "System.ValueType" and "System.Attribute" since
3570 they've already been populated from BootCorlib_PopulateCoreTypes().
3572 2002-06-29 Martin Baulig <martin@gnome.org>
3574 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
3575 is the NullLiteral, we also need to make sure that target_type is not
3578 2002-06-29 Martin Baulig <martin@gnome.org>
3580 * rootcontext.cs (RootContext.ResolveCore): We must initialize
3581 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
3582 before calling BootstrapCorlib_ResolveDelegate ().
3584 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3586 * statement.cs: fixed build-breaker. All tests passed ok.
3588 2002-06-27 Martin Baulig <martin@gnome.org>
3590 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
3591 for System.Decimal when compiling corlib.
3593 2002-06-27 Martin Baulig <martin@gnome.org>
3595 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
3596 switch blocks which contain nothing but a default clause.
3598 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
3600 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
3602 2002-06-27 Martin Baulig <martin@gnome.org>
3604 * ecore.cs (PropertyExpr.PropertyExpr): Call
3605 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
3607 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
3608 is already a TypeBuilder.
3610 2002-06-27 Martin Baulig <martin@gnome.org>
3612 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
3613 `target_type == TypeManager.array_type', not IsAssignableFrom() in
3614 the "from an array-type to System.Array" case. This makes it work
3615 when compiling corlib.
3617 2002-06-27 Martin Baulig <martin@gnome.org>
3619 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
3620 non-static PropertyExpr, set its InstanceExpression. This makes
3621 the `ICollection.Count' property work in System/Array.cs.
3623 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
3625 * driver.cs: Made error handling more consistent. Errors now
3626 tracked by Report class, so many methods which used to return int
3627 now return void. Main() now prints success/failure and
3628 errors/warnings message.
3630 Renamed '--probe' compiler argument to '--expect-error'. Removed
3631 the magic number return values (123 and 124). Now, if the
3632 expected error occurs, the compiler exits with success (exit value
3633 0). If the compilation completes without seeing that particular
3634 error, the compiler exits with failure (exit value 1). The
3635 makefile in mcs/errors has been changed to handle the new behaviour.
3637 * report.cs: Made 'expected error' number a property and renamed
3638 it from 'Probe' to 'ExpectedError'.
3640 * genericparser.cs: Removed error handling support, since it is
3641 now all done by Report class.
3643 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
3644 class, so parse() no longer returns an int.
3646 * namespace.cs: Use Report.Error instead of GenericParser.error
3648 2002-06-22 Miguel de Icaza <miguel@ximian.com>
3650 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
3651 TypeContainer.AddOperator): At the front of the list put the
3652 explicit implementations, so they get resolved/defined first.
3654 2002-06-21 Miguel de Icaza <miguel@ximian.com>
3656 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
3657 interface type is implemented by this TypeContainer. Used during
3658 explicit interface implementation.
3660 (Property.Define, Indexer.Define, Method.Define): Validate that
3661 the given interface in the explicit implementation is one of the
3662 base classes for the containing type.
3664 Also if we are explicitly implementing an interface, but there is
3665 no match in the pending implementation table, report an error.
3667 (Property.Define): Only define the property if we are
3668 not explicitly implementing a property from an interface. Use the
3669 correct name also for those properties (the same CSC uses,
3670 although that is really not needed).
3672 (Property.Emit): Do not emit attributes for explicitly implemented
3673 properties, as there is no TypeBuilder.
3675 (Indexer.Emit): ditto.
3677 Hiding then means that we do not really *implement* a pending
3678 implementation, which makes code fail.
3680 2002-06-22 Martin Baulig <martin@gnome.org>
3682 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
3683 the return value of Object.GetType(). [FIXME: we need to do this whenever
3684 we get a type back from the reflection library].
3686 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
3688 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
3690 2002-06-20 Miguel de Icaza <miguel@ximian.com>
3692 * attribute.cs: Return null if we can not look up the type.
3694 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
3695 the interface types found.
3697 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
3698 interface types found.
3700 * typemanager.cs (GetInterfaces): Make this routine returns alll
3701 the interfaces and work around the lame differences between
3702 System.Type and System.Reflection.Emit.TypeBuilder in the results
3703 result for GetInterfaces.
3705 (ExpandInterfaces): Given an array of interface types, expand and
3706 eliminate repeated ocurrences of an interface. This expands in
3707 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
3710 2002-06-21 Martin Baulig <martin@gnome.org>
3712 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
3715 2002-06-21 Martin Baulig <martin@gnome.org>
3717 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
3718 and called with one of the core types, return the corresponding typebuilder for
3721 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
3724 2002-06-21 Martin Baulig <martin@gnome.org>
3726 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
3727 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
3728 (Expression.ConvertReferenceExplicit): Likewise.
3730 * expression.cs (ElementAccess.DoResolve): Likewise.
3731 (ElementAccess.DoResolveLValue): Likewise.
3733 2002-06-10 Martin Baulig <martin@gnome.org>
3735 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
3736 add the "value" parameter to the parameter list.
3738 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
3741 2002-06-19 Miguel de Icaza <miguel@ximian.com>
3743 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
3744 the argument to an int, uint, long or ulong, per the spec. Also
3745 catch negative constants in array creation.
3747 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
3749 * class.cs: do not allow the same interface to appear twice in
3750 the definition list.
3752 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
3754 * ecore.cs: don't use ldlen with System.Array.
3756 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
3758 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
3760 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
3762 * modifiers.cs: produce correct field attributes for protected
3763 internal. Easy fix so miguel can work on ther harder stuff:-)
3765 2002-06-18 Miguel de Icaza <miguel@ximian.com>
3767 * pending.cs: New file. Move the code from class.cs here.
3768 Support clearning the pending flag for all methods (when not doing
3769 explicit interface implementation).
3771 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
3773 * rootcontext.cs: added a couple more types needed to bootstrap.
3775 2002-06-17 Miguel de Icaza <miguel@ximian.com>
3777 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
3778 constructor in the type, instead of any constructor in the type
3779 hierarchy. Thanks to Paolo for finding this bug (it showed up as
3780 a bug in the Mono runtime when applying the params attribute).
3782 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
3783 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
3785 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
3787 * expression.cs (Unary.ResolveOperator): Use TypeManager
3788 to resolve the type.
3790 2002-06-13 Ravi Pratap <ravi@ximian.com>
3792 * cs-parser.jay (enum_member_declaration): Pass in the attributes
3795 * enum.cs (AddEnumMember): Add support to store the attributes associated
3796 with each member too.
3798 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
3799 field builders too - this takes care of the enum member case.
3801 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
3803 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
3804 address-of operator on both value types and pointers.
3806 2002-06-10 Martin Baulig <martin@gnome.org>
3808 * interface.cs (Interface.PopulateIndexer): Add the indexer's
3809 PropertyBuilder to the `property_builders' list.
3811 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
3812 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
3813 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
3814 find any indexers which are inherited from an interface.
3816 2002-06-09 Martin Baulig <martin@gnome.org>
3818 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
3819 the same type as the constant if necessary. There's also a test-130.cs
3822 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
3824 * typemanager.cs (TypeManager.ChangeType): Previously known as
3825 Enum.ChangeEnumType().
3827 2002-06-09 Martin Baulig <martin@gnome.org>
3829 * expression.cs (Cast.TryReduce): Added support for consts.
3831 2002-06-08 Ravi Pratap <ravi@ximian.com>
3833 * class.cs (Accessor): Hold attributes information so we can pass
3836 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
3837 Modify to pass in attributes attached to the methods.
3839 (add_accessor_declaration, remove_accessor_declaration): Ditto.
3841 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
3842 to handle the Accessor kind :-)
3844 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
3846 2002-06-08 Martin Baulig <martin@gnome.org>
3848 * expression.cs (Unary.TryReduceNegative): Added support for
3851 2002-06-08 Martin Baulig <martin@gnome.org>
3853 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
3854 name can't be found in the `defined_names' - the caller will do a
3855 MemberLookup in this case and thus find methods in System.Enum
3856 such as Enum.IsDefined().
3858 2002-06-08 Martin Baulig <martin@gnome.org>
3860 * enum.cs (Enum.ChangeEnumType): This is a custom version of
3861 Convert.ChangeType() which works with TypeBuilder created types.
3862 (Enum.LookupEnumValue, Enum.Define): Use it here.
3864 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
3865 `TypeBuilder.BaseType != null' check.
3866 (TypeContainer.FindMembers): Only lookup parent members if we
3867 actually have a parent.
3868 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
3869 (ConstructorInitializer.Resolve): Likewise.
3871 * interface.cs (Interface.FindMembers): Added
3872 `TypeBuilder.BaseType != null' check.
3874 * rootcontext.cs (RootContext.ResolveCore): Added
3875 "System.Runtime.CompilerServices.IndexerNameAttribute" to
3876 classes_second_stage.
3878 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
3879 debug_type and trace_type when compiling with --nostdlib.
3881 2002-06-07 Martin Baulig <martin@gnome.org>
3883 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
3884 (AddField): Set it to true when adding a non-static field.
3885 (DefineType): Use `have_nonstatic_fields' to find out whether we
3886 have non-static fields, not `Fields != null'.
3888 2002-06-02 Miguel de Icaza <miguel@ximian.com>
3890 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
3891 dereferencing a null on the static-field code path)
3893 2002-05-30 Martin Baulig <martin@gnome.org>
3895 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
3896 to take command line arguments. Use reflection to call the new
3897 custom `Initialize' function on the symbol writer and pass it the
3898 command line arguments.
3900 * driver.cs (--debug-args): New command line argument to pass command
3901 line arguments to the symbol writer.
3903 2002-05-28 Miguel de Icaza <miguel@ximian.com>
3905 * assign.cs (DoResolve): Forgot to do the implicit conversion to
3906 the target type for indexers and properties. Thanks to Joe for
3909 2002-05-27 Miguel de Icaza <miguel@ximian.com>
3911 * typemanager.cs (MethodFlags): returns the method flags
3912 (Obsolete/ShouldIgnore) that control warning emission and whether
3913 the invocation should be made, or ignored.
3915 * expression.cs (Invocation.Emit): Remove previous hack, we should
3916 not do this on matching a base type, we should do this based on an attribute
3918 Only emit calls to System.Diagnostics.Debug and
3919 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
3920 on the command line.
3922 * rootcontext.cs: Global settings for tracing and debugging.
3924 * cs-tokenizer.cs (define): New utility function to track
3925 defines. Set the global settings for TRACE and DEBUG if found.
3927 2002-05-25 Ravi Pratap <ravi@ximian.com>
3929 * interface.cs (Populate*): Pass in the TypeContainer as well as
3930 the DeclSpace as parameters so that we can create EmitContexts and
3931 then use that to apply attributes etc.
3933 (PopulateMethod, PopulateEvent, PopulateProperty)
3934 (PopulateIndexer): Apply attributes everywhere.
3936 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
3939 (ApplyAttributes): Update accordingly.
3941 We now apply interface attributes for all members too.
3943 2002-05-26 Miguel de Icaza <miguel@ximian.com>
3945 * class.cs (Indexer.Define); Correctly check if we are explicit
3946 implementation (instead of checking the Name for a ".", we
3947 directly look up if the InterfaceType was specified).
3949 Delay the creation of the PropertyBuilder.
3951 Only create the PropertyBuilder if we are not an explicit
3952 interface implementation. This means that explicit interface
3953 implementation members do not participate in regular function
3954 lookups, and hence fixes another major ambiguity problem in
3955 overload resolution (that was the visible effect).
3957 (DefineMethod): Return whether we are doing an interface
3960 * typemanager.cs: Temporary hack until we get attributes in
3961 interfaces (Ravi is working on that) and we get IndexerName
3962 support in interfaces.
3964 * interface.cs: Register the indexers as properties.
3966 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
3967 warning, I have verified that this is a bug in the .NET runtime
3968 (JavaScript suffers of the same problem).
3970 * typemanager.cs (MemberLookup): When looking up members for
3971 interfaces, the parent of an interface is the implicit
3972 System.Object (so we succeed in searches of Object methods in an
3973 interface method invocation. Example: IEnumerable x; x.ToString
3976 2002-05-25 Miguel de Icaza <miguel@ximian.com>
3978 * class.cs (Event): Events should also register if they do
3979 implement the methods that an interface requires.
3981 * typemanager.cs (MemberLookup); use the new GetInterfaces
3984 (GetInterfaces): The code used to lookup interfaces for a type is
3985 used in more than one place, factor it here.
3987 * driver.cs: Track the errors at the bottom of the file, we kept
3990 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
3991 instance if the method we are calling is static!
3993 2002-05-24 Miguel de Icaza <miguel@ximian.com>
3995 * attribute.cs (ApplyAttributes): Make this function filter out
3996 the IndexerName attribute (as that attribute in reality is never
3997 applied) and return the string constant for the IndexerName
4000 * class.cs (TypeContainer.Emit): Validate that all the indexers
4001 have the same IndexerName attribute, and if so, set the
4002 DefaultName attribute on the class.
4004 * typemanager.cs: The return value might contain other stuff (not
4005 only methods). For instance, consider a method with an "Item"
4006 property and an Item method.
4008 * class.cs: If there is a problem with the parameter types,
4011 2002-05-24 Ravi Pratap <ravi@ximian.com>
4013 * ecore.cs (ImplicitConversionExists): Wrapper function which also
4014 looks at user defined conversion after making a call to
4015 StandardConversionExists - we need this for overload resolution.
4017 * expression.cs : Update accordingly the various method calls.
4019 This fixes 2 bugs filed against implicit user defined conversions
4021 2002-05-22 Miguel de Icaza <miguel@ximian.com>
4023 * statement.cs: Track the result of the assignment.
4025 2002-05-21 Miguel de Icaza <miguel@ximian.com>
4027 * expression.cs (MemberAccess): Improved error reporting for
4028 inaccessible members.
4030 2002-05-22 Martin Baulig <martin@gnome.org>
4032 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
4033 itself with debugging support.
4035 2002-05-22 Martin Baulig <martin@gnome.org>
4037 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
4038 Removed, this isn't needed anymore.
4040 2002-05-20 Martin Baulig <martin@gnome.org>
4042 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
4043 be underlying type for an enum.
4045 2002-05-20 Miguel de Icaza <miguel@ximian.com>
4047 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
4048 that splits out the loading of just the core types.
4050 * rootcontext.cs (ResolveCore): Split the struct resolution in
4051 two, so we can load the enumeration underlying types before any
4054 * expression.cs (Is): Bandaid until we fix properly Switch (see
4055 bug #24985 for details).
4057 * typemanager.cs (ImplementsInterface): The hashtable will contain
4058 a null if there are no interfaces implemented.
4060 2002-05-18 Miguel de Icaza <miguel@ximian.com>
4062 * cs-parser.jay (indexer_declarator): It is fine to have array
4065 2002-05-17 Miguel de Icaza <miguel@ximian.com>
4067 * typemanager.cs: (RegisterBuilder): New function used to register
4068 TypeBuilders that implement interfaces. Since
4069 TypeBuilder.GetInterfaces (as usual) does not work with lame
4071 (AddUserType): register interfaces.
4073 (ImplementsInterface): Use the builder_to_ifaces hash if we are
4074 dealing with TypeBuilder. Also, arrays are showing up as
4075 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
4076 methods can not be invoked on them!
4078 * ecore.cs (ExplicitReferenceConversionExists): Made public.
4079 (ImplicitReferenceConversionExists): Split out from
4080 StandardConversionExists.
4082 * expression.cs (As): We were only implementing one of the three
4083 cases for the as operator. We now implement them all.
4084 (Is): Implement the various other cases for Is as well.
4086 * typemanager.cs (CACHE): New define used to control if we want or
4087 not the FindMembers cache. Seems to have a negative impact on
4088 performance currently
4090 (MemberLookup): Nested types have full acess to
4091 enclosing type members
4093 Remove code that coped with instance/static returns for events, we
4094 now catch this in RealFindMembers.
4096 (RealFindMembers): only perform static lookup if the instance
4097 lookup did not return a type or an event.
4099 2002-05-17 Miguel de Icaza <miguel@ximian.com>
4101 * assign.cs (CompoundAssign): We pass more semantic information
4102 now to Compound Assignments than we did before: now we have all
4103 the information at hand, and now we resolve the target *before* we
4104 do the expression expansion, which allows the "CacheValue" method
4105 to have the effect we intended (before, a [x] += 1 would generate
4106 two differen ArrayAccess expressions from the ElementAccess,
4107 during the resolution process).
4109 (CompoundAssign.DoResolve): Resolve target and original_source here.
4111 2002-05-16 Miguel de Icaza <miguel@ximian.com>
4113 * expression.cs (ArrayAccess): dropped debugging information.
4115 * typemanager.cs: Small bug fix: I was always returning i_members,
4116 instead of one of i_members or s_members (depending on which had
4119 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
4120 method is invoked before any code generation takes place, and it
4121 is a mechanism to inform that the expression will be invoked more
4122 than once, and that the method should use temporary values to
4123 avoid having side effects
4125 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
4127 * ecore.cs (Expression.CacheTemporaries): Provide empty default
4130 * expression.cs (Indirection, ArrayAccess): Add support for
4131 CacheTemporaries in these two bad boys.
4133 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
4135 (StoreFromPtr): Handle stobj as well.
4137 * expression.cs (UnaryMutator): Share more code.
4139 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
4140 down: I was not tracking the Filter function as well, which
4141 was affecting the results of the cache.
4143 2002-05-15 Miguel de Icaza <miguel@ximian.com>
4145 * attribute.cs: Remove the hack to handle the CharSet property on
4148 2002-05-14 Miguel de Icaza <miguel@ximian.com>
4150 * attribute.cs (DoResolve): More uglyness, we now only try to
4151 resolve the attribute partially, to extract the CharSet
4152 information (only if we are a StructLayout attribute). Otherwise
4154 (GetExtraTypeInfo): Add some code to conditionally kill in the
4155 future this. I am more and more convinced that the .NET
4156 framework has special code to handle the attribute setting on
4159 * expression.cs (IsParamsMethodApplicable): Revert my previous
4160 foreach change here, it was wrong.
4162 2002-05-13 Miguel de Icaza <miguel@ximian.com>
4164 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
4165 (pp_expr): do not abort on unknown input, just return.
4166 (eval): abort if there are pending chars.
4168 * attribute.cs (Attribute.Resolve): Positional parameters are
4169 optional. Deal with that case.
4171 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
4172 the Ansi/Unicode/Auto information for the type.
4174 (TypeContainer.DefineType): instantiate the EmitContext here, as
4175 we will be using it during the type definition (to resolve
4176 attributes) and during the emit phase.
4178 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
4179 to pull type information out of the attributes
4181 (Attribute.Resolve): track the constructor builder, and allow for
4182 multiple invocations (structs and classes will use this).
4184 * ecore.cs (MemberLookupFinal): new version with all the
4185 parameters customizable.
4187 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
4188 constructors. Return if the result value is null (as the error
4189 would have been flagged already by MemberLookupFinal)
4191 Do not allow instances of abstract classes or interfaces to be
4194 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
4195 We have to compare the assembly property here when dealing with
4196 FamANDAssem and Assembly access modifiers, because we might be
4197 creating an assembly from *modules* (that means that we are not
4198 getting TypeBuilders for types defined in other modules that are
4199 part of this assembly).
4201 (Method.Emit): If the method is marked abstract and has a body,
4204 (TypeContainer.DefineMembers): If both the defined member and the
4205 parent name match are methods, then do not emit any warnings: let
4206 the Method.Define routine take care of flagging warnings. But if
4207 there is a mismatch (method overrides something else, or method is
4208 overriwritten by something, then emit warning).
4210 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
4211 set to null, this means `do not check for the return type on the
4214 (Method.Define): set the return type for the method signature to
4215 null, so that we get methods with the same name and parameters and
4216 different return types. This is used to flag warning 114 (you are
4217 hiding a method, and you probably want to use the new/override
4220 * typemanager.cs (MemberLookup): Implemented proper access
4221 control, closing a long standing set of bug reports. The problem
4222 was that the Framework only has two bits: Public and NonPublic,
4223 and NonPublic includes private and protected methods, but we need
4224 to enforce the FamANDAssem, FamOrAssem and Family.
4226 2002-05-11 Miguel de Icaza <miguel@ximian.com>
4228 * statement.cs (GotoCase): Return true: Ammounts to giving up
4229 knowledge on whether we return or not, and letting the other case
4230 be responsible for it.
4232 2002-05-10 Miguel de Icaza <miguel@ximian.com>
4234 * driver.cs: Do not load directories for each file processed, only
4235 do it if there is a pattern.
4237 * ecore.cs: Report readonly assigns here as well, as we might have
4238 been resolved only by MemberAccess.
4240 (SimpleName.SimpleNameResolve): Also be useful for LValue
4241 resolution. We need this to propagate assign to local readonly variables
4243 * typemanager.cs: Use a ptrhashtable for the criteria, because we
4244 do not want to reuse potential criteria memory.
4246 * class.cs (MyEventBuilder): Set reflected_type;
4248 * ecore.cs (Constantify): Added support for constifying bools.
4250 (RootContext.LookupType): Added a cache for values looked up in
4251 the declaration space.
4253 * typemanager.cs (FindMembers): Now is a front-end to
4254 RealFindMembers, and provides a two-level hashtable-based cache to
4257 15% performance improvement: from 22.5 to 19.2 seconds.
4259 * expression.cs (IsParamsMethodApplicable): use foreach.
4260 (Invocation.DoResolve): ditto.
4261 (New.DoResolve): ditto.
4262 (ArrayCreation.DoResolve): ditto.
4264 * ecore.cs (FindMostEncompassingType): use foreach.
4266 * delegate.cs (NewDelegate.DoResolve): Use foreach
4268 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
4269 (RemoveMethods): use foreach.
4271 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
4272 nested foreach statements instead of for, and also break out of
4273 the inner loop once a match is found.
4275 (Invocation.OverloadResolve): Use foreach, simplify the code.
4277 2002-05-08 Miguel de Icaza <miguel@ximian.com>
4279 * cfold.cs (BinaryFold): During an enumeration evaluation context,
4280 we actually unwrap the expression to allow for extra information
4283 * expression.cs: Use Shr_Un on unsigned operations.
4285 2002-05-08 Ravi Pratap <ravi@ximian.com>
4287 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
4288 applicable operators was not being considered correctly. This closes
4289 the bug Miguel reported.
4291 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
4293 * attribute.cs: check that the type derives from System.Attribute
4294 and report the correct error in that case (moved the duplicate code to
4295 its own method, too).
4297 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
4299 * attribute.cs: lookup attribute type name as the spec says: first the
4300 bare attribute name and then name + "Attribute" (nant compiles with
4301 mcs after this fix).
4303 2002-05-07 Miguel de Icaza <miguel@ximian.com>
4305 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
4306 Because of the way we parse things, we should try to see if a
4307 UIntConstant can fit in an integer.
4309 2002-05-07 Ravi Pratap <ravi@ximian.com>
4311 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
4312 when we are in an explicit context.
4314 (ConvertReferenceExplicit): When converting from Iface type S to Class
4315 T make sure the rules are implemented as an OR.
4317 * parameter.cs (ParameterType): Make it a property for now although the
4318 purpose really isn't anything immediate.
4320 * expression.cs (Is*Applicable): Do better checking on the parameter type
4321 of a ref/out parameter. The ones from the system assemblies are already
4322 marked with the correct type so we don't need to do any correction.
4324 * ecore.cs (StandardConversionExists): Conversion from Interface types to
4325 the object type is standard too so include that.
4327 2002-05-06 Miguel de Icaza <miguel@ximian.com>
4329 * ecore.cs (StandardConversionExists): Augment with missing code:
4330 deal with IntConstant, LongConstants and Enumerations.
4332 * assign.cs: Report the error, instead of failing silently
4334 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
4335 typecontainer that they are declared, because the
4336 typecontainer/namespace will have the list of using clauses that
4339 Assembly Attributes were escaping the normal registration
4342 (EmitCode): Apply attributes within an EmitContext that represents
4343 the container they were declared on.
4345 * cs-parser.jay: Track bases for structs. How did I get this wrong?
4347 2002-05-06 Ravi Pratap <ravi@ximian.com>
4349 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
4350 Revamp completely - make much cleaner as we now operate only
4353 (FindMostSpecificSource, FindMostSpecificTarget): New methods
4354 to implement the logic detailed in the spec more correctly.
4356 (UserDefinedConversion): Update accordingly.
4358 2002-05-06 Miguel de Icaza <miguel@ximian.com>
4360 * statement.cs: Return flow analysis information up.
4362 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
4365 (token): Do not consume an extra character before calling
4368 2002-05-06 Piers Haken <piersh@friskit.com>
4370 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
4372 2002-05-06 Miguel de Icaza <miguel@ximian.com>
4374 * class.cs (Constructor.Emit): Set the IsStatic flag in the
4375 EmitContext during the instance constructor initializer
4376 resolution, to stop access to instance variables.
4378 This is mandated by the spec, last paragraph of the `constructor
4379 initializers' section.
4381 2002-05-05 Miguel de Icaza <miguel@ximian.com>
4383 * cs-parser.jay, class.cs (Accessor): new class used to represent
4384 an accessor (get or set). In the past we used `null' to represent
4385 a missing accessor. But this is ambiguous because there was no
4386 way to tell in abstract indexers/properties if one of them was
4389 Now there is a way of addressing that.
4391 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
4392 instead of FindMembers.
4394 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
4395 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
4397 * attribute.cs: Treat indexers and properties as the same in terms
4398 of applying attributes
4400 * ecore.cs (FindMostEncompassedType): Use statically initialized
4401 EmptyExpressions()s like we do elsewhere to avoid creating useless
4402 objects (and we take this out of the tight loop).
4404 (GetConversionOperators): Move the code to extract the actual
4405 operators to a separate routine to clean things up.
4407 2002-05-04 Miguel de Icaza <miguel@ximian.com>
4409 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
4410 events are always registered FieldBuilders.
4412 * class.cs (FieldBase): New class shared by Fields
4414 * delegate.cs: If we are a toplevel delegate, use our full name.
4415 If we are a nested delegate, then only use our tail name.
4417 2002-05-02 Ravi Pratap <ravi@ximian.com>
4419 * expression.cs (IsApplicable): Ensure that we add the "&" to
4420 ref/out types before comparing it with the type of the argument.
4422 (IsParamsMethodApplicable): Ditto.
4424 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
4427 * delegate.cs : Handle the case when we have more than one applicable
4428 method. Flag an error only when we finish checking all.
4430 2002-05-02 Miguel de Icaza <miguel@ximian.com>
4432 * expression.cs: Add support for boolean static initializers.
4434 2002-05-01 Miguel de Icaza <miguel@ximian.com>
4436 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
4438 * parameter.cs (ComputeParameterTypes,
4439 ComputeAndDefineParameterTypes): Better error handling: now we
4440 clear the `types' cache if we fail during any of the type lookups.
4441 We also return the status code correctly to our caller
4443 * delegate.cs: If we fail to define a delegate, abort the extra
4446 * expression.cs (Binary.ResolveOperator): for
4447 operator==(object,object) and operator !=(object, object) we also
4448 have to verify that there is an implicit conversion from one to
4451 (ArrayAccess.DoResolve): Array Access can operate on
4454 2002-04-30 Miguel de Icaza <miguel@ximian.com>
4456 * assign.cs (CompoundAssign): A new class used as a "flag" that
4457 the assignment actually is happening as part of a compound
4458 assignment operator.
4460 During compound assignment, a few new rules exist to enable things
4467 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
4468 to the type of x) if y is implicitly convertible to the type of x,
4469 and the operator is a builtin operator and the return type of the
4470 operator is explicitly convertible to the type of x.
4472 * rootcontext.cs: Reset warning level to 2. 4 catches various
4473 "interesting" features in mcs, we must clean this up at some
4474 point, but currently am trying to kill other bugs ;-)
4476 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
4477 in container classes as well.
4479 * expression.cs (Binary.ResolveOperator): Handle string case
4480 before anything else (as operator overloading does emit an error
4481 before doing anything else).
4483 This code could go away when we move to a table driven model, but
4484 i could not come up with a good plan last night.
4486 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
4488 * typemanager.cs (CSharpName): reimplementation using regex.
4489 * class.cs: added null check for fields in Emit
4490 * rootcontext.cs: set warninglevel to 4
4492 2002-04-29 Miguel de Icaza <miguel@ximian.com>
4494 * typemanager.cs (CSharpName): reimplemented with Lupus
4497 2002-04-28 Miguel de Icaza <miguel@ximian.com>
4499 * statement.cs (If): correclty implement Resolve, because we were
4500 not catching sem errors in there. The same process is needed
4502 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
4505 (Statement.Warning_DeadCodeFound): Factorize code.
4506 (While): Report dead code here too.
4508 (Statement): Added Resolve virtual method to allow
4509 for resolution split from the emit code.
4511 2002-04-26 Miguel de Icaza <miguel@ximian.com>
4513 * statement.cs (EmitBoolExpression): No longer try to resolve the
4515 (MakeBoolean): New utility function that resolve, implicitly
4516 converts to boolean and tags the expression.
4519 (If, Do): Implement dead code elimination.
4520 (While): Implement loop inversion
4522 (Do, While, For, If): Resolve the expression prior to calling our
4525 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
4528 - added method Report28 (warning: program has more than one entry point)
4529 - added method IsEntryPoint, implements paragraph 10.1 of the spec
4530 - modified method Method.Define, the part at the end of the method
4532 * rootcontext.cs: added static public Location EntryPointLocation;
4534 * ../errors/cs0028.cs : Add test case for the above warning.
4537 - modified method CSharpName to allow arrays of primitive type to
4538 be printed nicely (e.g. instead of System.Int32[][] it now prints
4540 - added method CSharpSignature: returns the signature of a method
4541 in string format to be used in reporting errors, warnings, etc.
4543 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
4546 2002-04-26 Ravi Pratap <ravi@ximian.com>
4548 * delegate.cs (Define): Fix extremely silly bug where I was
4549 setting the type of the 'object' parameter of the BeginInvoke
4550 method to System.IAsyncResult instead of System.Object ;-)
4552 2002-04-26 Miguel de Icaza <miguel@ximian.com>
4554 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
4557 (Constructor.Emit): return if we fail to initialize the
4558 constructor. Another door closed!
4560 * expression.cs (New.DoResolve): Improve error message (from -6 to
4561 1501). Use DeclaredOnly lookup to find the exact constructor.
4563 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
4564 loop. This is useful.
4566 * cs-parser.jay: Adjust the default parameters so that destructors
4567 have the proper signature.
4569 2002-04-26 Martin Baulig <martin@gnome.org>
4571 * driver.cs (LoadAssembly): If `assembly' contains any characters
4572 which are only valid in path names and not in assembly names
4573 (currently slash, backslash and point), use Assembly.LoadFrom ()
4574 instead of Assembly.Load () on the `assembly' (before iteration
4575 over the link_paths).
4577 2002-04-26 Martin Baulig <martin@gnome.org>
4579 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
4581 2002-04-25 Miguel de Icaza <miguel@ximian.com>
4583 * class.cs (Property): use the new typemanager.MemberLookup
4585 (TypeContainer.MemberLookup): Implement using the
4586 TypeManager.MemberLookup now.
4588 * typemanager.cs: Make MemberLookup a function of the TypeManager,
4589 and return MemberInfos, so that these can be used without an
4590 EmitContext (what we had before).
4592 2002-04-24 Miguel de Icaza <miguel@ximian.com>
4594 * expression.cs: Fix the case where the argument to params if the
4595 type of the params. I omitted handling this before. Fixed
4597 2002-04-22 Miguel de Icaza <miguel@ximian.com>
4599 * driver.cs: Call BootCorlib_PopulateCoreType
4601 * class.cs (Property.CheckBase): Check for properties only, not
4604 * interface.cs: Temporary hack: try/catch around the
4605 CustomAttributeBuilder, because I am getting an exception that I
4608 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
4609 types whose definitions are required to be there (attributes are
4610 defined before standard types).
4612 Compute definitions as we boot the various types, as they are used
4613 immediately (value_type class will need object_type, but if we do
4614 not initialize object_type, we will pass a null, which will let
4615 the runtime pick the System.Object from the existing corlib, which
4616 is not what we want).
4618 2002-04-22 Patrik Torstensson <totte@labs2.com>
4620 * cs-tokenizer.cs: fixed a number of trim() issues.
4622 2002-04-22 Ravi Pratap <ravi@ximian.com>
4624 * expression.cs (Argument.Type): Ensure that we return the correct
4625 type when we have out or ref parameters [in which case we
4628 2002-04-22 Miguel de Icaza <miguel@ximian.com>
4630 * class.cs (Property, Indexer): Allow extern modifier in there.
4632 * typemanager.cs (InitBaseTypes): Initializes object_type and
4633 value_type, since those will be used early on during the bootstrap
4634 process to compile corlib.
4636 (InitCoreTypes): Move code from here to InitBaseTypes.
4638 2002-04-21 Miguel de Icaza <miguel@ximian.com>
4640 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
4641 single-dimension arrays as using the ldlen opcode.
4643 Daniel Lewis discovered this optimization.
4645 * typemanager.cs: Add signature for System.Array::get_Length
4647 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
4649 * statement.cs: report the error when the foreach does not apply to an
4650 array nor a collection.
4652 2002-04-19 Miguel de Icaza <miguel@ximian.com>
4654 * expression.cs: Add implicit conversions to the operator ~.
4656 * constant.cs (DecimalConstant.Emit): Emit decimal value.
4658 * typemanager.cs: Locate the decimal constructor.
4660 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
4662 * attribute.cs: use the new property of TypeOf.
4663 * expression.cs: added 'get' property around typearg.
4665 These changes fix a build breaker reported by NickD. Is this the
4666 correct way to fix? If not, please, revert my changes and make it
4669 2002-04-17 Miguel de Icaza <miguel@ximian.com>
4671 * attribute.cs: Add support for typeof in attribute invocations.
4672 I am not sure that this is right though.
4674 2002-04-14 Duncan Mak <duncan@ximian.com>
4676 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
4677 Binary.Operator.Division case.
4679 2002-04-13 Ravi Pratap <ravi@ximian.com>
4681 * class.cs (DefineType): Ensure that we do a proper check on
4682 attribute types and also register it with the TypeManager.
4684 (TypeContainer.Targets): The default for attribute types is
4685 AttributeTargets.All.
4687 * attribute.cs (ApplyAttributes): Registering the attribute type
4688 is done elsewhere, not when we discover we have a Usage attribute.
4690 2002-04-12 Ravi Pratap <ravi@ximian.com>
4692 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
4693 and get rid of is_delegate parameter.
4695 * everywhere : update.
4697 2002-04-12 Ravi Pratap <ravi@ximian.com>
4699 * cs-parser.jay (compilation_unit): Revamp completely to use
4700 some new ideas that I got from Rhys' grammar to solve the problems
4701 with assembly level attributes.
4703 (outer_declaration): New grammar production.
4705 (attribute_sections): Add.
4707 (opt_attributes): Base on attribute_sections
4709 (namespace_declaration): Allow opt_attributes to tackle the case
4710 when we have assembly level attributes - we are clever in this
4713 * attribute.cs (ApplyAttributes): Do not worry about assembly
4714 attributes in the non-global context.
4716 * rootcontext.cs (AddGlobalAttributes): Go back to using this
4717 instead of SetGlobalAttributes.
4719 * class.cs, rootcontext.cs : Ensure we define and generate
4720 attribute types before anything else.
4722 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
4723 and flag the new error -20 for the case when the attribute type
4724 does not have valid targets specified. csc does not catch this.
4726 * ../errors/errors.txt : update for error # -20
4728 2002-04-11 Ravi Pratap <ravi@ximian.com>
4730 * support.cs (InternalParameters.ParameterModifier): Do some null
4731 checking and return sane values.
4733 * class.cs (Method.Define): If we are a PInvoke method, ensure
4734 that we are static and extern. Report error # 601
4736 * ../errors/cs0601.cs : Add test case for the above error.
4738 2002-04-07 Ravi Pratap <ravi@ximian.com>
4740 * rootcontext.cs (attribute_types): We need to keep type of
4741 all attribute types separately and emit code for them first.
4743 (RegisterAttribute) : Implement.
4745 * class.cs (DefineType): Check if the current Type is a custom
4746 attribute type and register it accordingly.
4748 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
4749 adding the first attribute twice and rename to
4751 (SetGlobalAttributes): this.
4753 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
4756 * attribute.cs (ApplyAttributes): Take an additional argument telling us
4757 if we are processing global arguments. Hmm, I am unsure of this.
4759 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
4761 * expression.cs: added static array of strings to avoid calling
4762 Enum.ToString () for Operator in Binary. Significant recover of
4765 2002-04-10 Miguel de Icaza <miguel@ximian.com>
4767 * class.cs (FindMembers): Allow the Builders of the various
4768 members to be null. If they are skip them. This only happens
4769 during the PInvoke declaration.
4771 2002-04-09 Miguel de Icaza <miguel@ximian.com>
4773 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
4774 failure, so we do not keep going afterwards.
4776 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
4777 wanted to pass `false' as the `is_delegate' argument. If this is
4778 the case, why not use delegate_type == null to mean `is_delegate =
4779 false' and anything else as is_delegate = true.
4781 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
4783 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
4784 code for the section, not the beginning of the tests.
4786 2002-04-08 Miguel de Icaza <miguel@ximian.com>
4788 * cfold.cs: Handle operator + (Enum x, Underlying x)
4790 * expression.cs (Binary): same. Warn about errors where we have
4791 Enum/Enum in operator + as well.
4793 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
4796 - added support for switch(bool)
4797 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
4798 - add TableSwitchEmit() to handle table-based switch statements
4800 2002-04-05 Ravi Pratap <ravi@ximian.com>
4802 * expression.cs (Invocation.OverloadResolve): Factor out code which
4803 does parameter compatibility checking with arguments so that we can
4804 re-use the code even from Delegate.VerifyApplicability
4806 (VerifyArgumentsCompat): Move above code here.
4808 * delegate.cs (VerifyApplicability): Get rid of duplicate code
4809 and instead make a call to the above method.
4811 2002-03-31 Ravi Pratap <ravi@ximian.com>
4813 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
4814 We use it to keep track of classes which are attribute types.
4816 2002-04-02 Miguel de Icaza <miguel@ximian.com>
4818 * delegate.cs (Delegate.Define): Correctly define the types in the
4819 presence of fixed and array parameters.
4821 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
4824 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
4825 include NonPublic after the first iteration.
4827 * class.cs (Indexer.CheckBase): Only check if both parents are
4830 * cs-parser.jay (accessor_body): If empty, set to null.
4832 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
4833 same code path here to resolve constants names that we did have in
4834 MemberAccess.DoResolve. There is too much code duplicated here.
4836 2002-04-01 Miguel de Icaza <miguel@ximian.com>
4838 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
4840 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
4843 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
4844 tokens, numbers and strings.
4846 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
4849 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
4850 asyncronous parameters and the regular parameters.
4852 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
4853 specify the target directory.
4855 * expression.cs: (This.DoResolve): Simplify
4856 (As.Emit): Optimize, do not generate IsInst if the expression is
4857 always of the given type.
4859 (Is.DoResolve): Bug fix, we were reporting both always/never for
4862 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
4863 creating too many unnecessary arrays.
4865 2002-03-31 Miguel de Icaza <miguel@ximian.com>
4867 * class.cs (EmitFieldInitializer): Use Assign expression to assign
4868 fields instead of rolling our own initializer. Takes care of all
4869 implicit conversions, and drops unnecessary static checks/argument.
4871 2002-03-31 Dick Porter <dick@ximian.com>
4873 * driver.cs: use the GetDirectories() return values properly, and
4874 use "/" as path separator.
4876 2002-03-30 Miguel de Icaza <miguel@ximian.com>
4878 * expression.cs (Unary): Optimize - - expr into expr.
4879 (Binary): Optimize a + (-b) into a -b.
4881 * codegen.cs (CodeGen): Made all methods static.
4883 2002-03-29 Miguel de Icaza <miguel@ximian.com>
4887 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
4888 TypeBuilder property.
4890 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
4893 * tree.cs: Removed the various RecordXXXX, and replaced with a
4894 single RecordDecl. Removed all the accessor methods, and just
4895 left a single access point Type
4897 * enum.cs: Rename DefineEnum to DefineType.
4899 * decl.cs: New abstract method `DefineType' used to unify the
4900 Defines for Enumerations, Interfaces, TypeContainers and
4903 (FindType): Moved LookupInterfaceOrClass here. Moved the
4904 LookupBaseClasses method that used to live in class.cs and
4905 interface.cs here, and renamed to FindType.
4907 * delegate.cs: Implement DefineType. Take advantage of the
4908 refactored pattern for locating the parent builder without taking
4909 the parent_builder argument (which we know does not work if we are
4910 nested, and triggering a toplevel definition).
4912 2002-03-28 Miguel de Icaza <miguel@ximian.com>
4914 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
4915 accessibility of a member has changed during override and report
4918 * class.cs (Method.Define, Property.Define): Only complain on
4919 overrides if the method is private, any other accessibility is
4920 fine (and since we just checked the permission is the same, we are
4923 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
4924 and elif are processed always. The other pre-processing
4925 directives are only processed if we are "taking" the path
4927 2002-03-29 Martin Baulig <martin@gnome.org>
4929 * class.cs (Method.Emit): Only emit symbolic debugging info if the
4930 current location is not Null.
4932 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
4933 a separate method so we can profile it.
4935 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
4936 `span.Seconds' are just seconds, but no minutes or hours.
4937 (MainDriver): Profile the CodeGen.SaveSymbols calls.
4939 2002-03-28 Miguel de Icaza <miguel@ximian.com>
4941 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
4942 Remove the gratuitous set of Final:
4944 // If an interface implementation, then we can set Final.
4945 if (((flags & MethodAttributes.Abstract) == 0) &&
4946 implementing.DeclaringType.IsInterface)
4947 flags |= MethodAttributes.Final;
4949 I do not know what I was smoking when I used that.
4952 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
4953 step into fixing the name resolution issues for delegates and
4954 unifying the toplevel name resolution.
4956 2002-03-28 Martin Baulig <martin@gnome.org>
4958 * class.cs (Method.Emit): If we have a symbol writer, call its
4959 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
4960 tell it about the current method.
4962 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
4963 writer that we're going to emit the first byte of IL code for a new
4964 statement (a new source line).
4965 (EmitContext.EmitTopBlock): If we have a symbol writer, call
4966 EmitContext.Mark() before emitting any code.
4968 * location.cs (SymbolDocument): Return null when we're Null.
4970 * statement.cs (Statement): Moved the `Location loc' variable here.
4971 (Statement.EmitBoolExpression): If we have a symbol writer, call
4972 ec.Mark() before emitting any code to tell it that we're at the
4973 beginning of a new statement.
4974 (StatementExpression): Added `Location' argument to the constructor.
4975 (Block): Added public readonly variable `StartLocation' and public
4976 variable `EndLocation'. The latter is to be set using SetEndLocation().
4977 (Block): Added constructor which takes a start and end location.
4978 (Block.SetEndLocation): New method. This sets the end location.
4979 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
4980 local variables we create.
4981 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
4982 each statement and do also mark the begin and end of the block.
4984 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
4985 tell it the current lexer.Location, use Location.Null for the end of the
4987 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
4988 current block, set its end location using SetEndLocation().
4989 (statement_expression): StatementExpression constructor now takes the
4990 lexer.Location as additional argument.
4991 (for_statement, declare_local_variables): Likewise.
4992 (declare_local_variables): When creating a new implicit block, use the
4993 new Block constructor and pass it the lexer.Location.
4995 2002-03-28 Miguel de Icaza <miguel@ximian.com>
4997 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
4998 members also on the parent interfaces recursively.
5000 2002-03-27 Miguel de Icaza <miguel@ximian.com>
5002 * report.cs: Use new formats, since Gonzalo finished the missing
5005 * expression.cs (Binary.ResolveOperator): added missing operator|
5006 operator& and operator^ for bool/bool.
5008 * cs-parser.jay: CheckDef now takes a Location argument that is
5009 used to report errors more precisly (instead of reporting the end
5010 of a definition, we try to track something which is a lot closer
5011 to the source of the problem).
5013 * cs-tokenizer.cs: Track global token use, so we can properly flag
5014 the use of #define/#undef after the first token has been seen.
5016 Also, rename the reportXXXX to Error_DescriptiveName
5018 * decl.cs (DeclSpace.IsTopLevel): Move property here from
5019 TypeContainer, so that Enum and Interface can use this too.
5021 * class.cs (TypeContainer.LookupInterfaceOrClass,
5022 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
5023 `builder' argument. Typically this was used to pass the parent
5024 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
5027 The problem is that a nested class could trigger the definition of
5028 a toplevel class, and the builder would be obviously wrong in that
5031 So we drop this argument, and we compute dynamically the
5032 TypeBuilder/ModuleBuilder (the correct information was available
5033 to us anyways from DeclSpace.Parent)
5035 * interface.cs (Interface.DefineInterface): Drop builder
5036 parameter cleanup like class.cs
5038 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
5041 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
5044 (Try.Emit): Propagate the returns value from the statement.
5046 (Return.Emit): Even if we are leavning
5048 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
5050 * modifiers.cs: Fix the computation of MethodAttributes flags.
5052 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
5054 * driver.cs: allow compilation of files that start with '/'.
5055 Add a default case when checking the argument of --target.
5057 2002-03-25 Miguel de Icaza <miguel@ximian.com>
5059 * interface.cs: Implement the same search algorithm for types in
5062 * delegate.cs: Do not allow multiple definition.
5064 * Recovered ChangeLog that got accidentally amputated
5066 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
5068 * rootcontext.cs: Load manually enum to allow core classes to
5069 contain enumerations.
5071 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
5072 Update to new static methods in TypeManager.
5074 * typemanager.cs (GetMethod, GetConstructor): Use our
5075 implementation of FindMembers to find the members, since during
5076 corlib compilation, the types are TypeBuilders and GetMethod and
5077 GetConstructor do not work.
5079 Make all methods in TypeManager static.
5081 (InitCodeHelpers): Split the functionality from
5082 the InitCodeTypes function.
5084 * driver.cs: Call InitCodeHelpers after we have populated the
5087 * cs-parser.jay (delegate_declaration): we did not used to compute
5088 the delegate name correctly for void delegates.
5090 2002-03-24 Miguel de Icaza <miguel@ximian.com>
5092 * rootcontext.cs (RootContext): Init the interface_resolve_order
5093 and type_container_resolve_order always.
5095 (ResolveCore, BootstrapCorlib_ResolveClass,
5096 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
5097 compiler when compiling with --nostdlib
5099 * class.cs (TypeContainer.DefineType): Check that our parent is
5100 not null. This test is most important when we are bootstraping
5103 * codegen.cs: Split out the symbol writing code.
5105 2002-03-25 Martin Baulig <martin@gnome.org>
5107 * driver.cs (-g): Made -g an alias for --debug.
5109 2002-03-24 Martin Baulig <martin@gnome.org>
5111 * codegen.cs (SymbolWriter): New public variable. Returns the
5112 current symbol writer.
5113 (CodeGen): Added `bool want_debugging_support' argument to the
5114 constructor. If true, tell the ModuleBuild that we want debugging
5115 support and ask it for the ISymbolWriter.
5116 (Save): If we have a symbol writer, call it's Close() method after
5117 saving the assembly.
5119 * driver.c (--debug): New command line argument to create a
5120 debugger information file.
5122 * location.cs (SymbolDocument): New public property. Returns an
5123 ISymbolDocumentWriter object for the current source file or null
5124 if we don't have a symbol writer.
5126 2002-03-21 Miguel de Icaza <miguel@ximian.com>
5128 * driver.cs (LoadAssembly): Correctly return when all the paths
5129 have been tried and not before.
5131 * statement.cs (Switch.Emit): return the actual coverage for this
5132 statement (returns/not-returns)
5134 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
5135 switch of the statement if we are the last switch section. That
5136 kills two problems: try/catch problems (we used to emit an empty
5137 nop at the end) and switch statements where all branches would
5140 2002-03-19 Miguel de Icaza <miguel@ximian.com>
5142 * driver.cs: Add default assemblies (the equivalent to the
5143 Microsoft CSC.RSP file)
5145 * cs-tokenizer.cs: When updating `cols and setting it to zero,
5146 also update tokens_seen and set it to false.
5148 * driver.cs: Implement --recurse for Mike.
5150 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
5151 correctly splitting out the paths.
5153 2002-03-18 Miguel de Icaza <miguel@ximian.com>
5155 * interface.cs (Interface.PopulateProperty): Instead of using
5156 `parent' as the declaration space for the set parameters, use
5159 * support.cs (InternalParameters): InternalParameters constructor
5160 takes a DeclSpace instead of a TypeContainer.
5162 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
5163 types are being initialized, load the address of it before calling
5166 (New): Provide a mechanism to disable the generation of local
5167 value type temporaries when the caller will be providing us with
5168 an address to store it.
5170 (ArrayCreation.EmitDynamicInitializers): Use it.
5172 2002-03-17 Miguel de Icaza <miguel@ximian.com>
5174 * expression.cs (Invocation.EmitArguments): Only probe for array
5175 property if there is more than one argument. Sorry about that.
5177 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
5180 * class.cs (Method.LabelParameters): Fix incorrect code path that
5181 prevented the `ParamArrayAttribute' from being applied to the
5184 2002-03-16 Miguel de Icaza <miguel@ximian.com>
5186 * support.cs (ReflectionParameters): Correctly compute whether the
5187 last argument is a params array. Fixes the problem with
5190 * typemanager.cs: Make the assemblies array always be non-null
5191 (empty, but non-null)
5193 * tree.cs (RecordDecl): New function that abstracts the recording
5194 of names. This reports error 101, and provides a pointer to the
5195 previous declaration. Fixes a crash in the compiler.
5197 * cs-parser.jay (constructor_declaration): Update to new grammar,
5198 and provide a constructor_body that can be empty.
5200 2002-03-15 Miguel de Icaza <miguel@ximian.com>
5202 * driver.cs: Add support for --resources.
5204 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
5205 Make all types for the various array helper methods be integer.
5207 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
5208 CheckState to ConvCast.
5210 (ConvCast): Now it takes a `checked' state argument, to avoid
5211 depending on the emit context for the conversion, and just using
5212 the resolve time setting.
5214 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
5215 instead of Invocation.EmitArguments. We do not emit the original
5216 arguments, instead we emit those which have been converted to
5217 unsigned int expressions.
5219 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
5221 * codegen.cs: ditto.
5223 * expression.cs (LocalVariableReference): Drop the use of the
5224 Store function that depended on the variable index.
5226 * statement.cs (VariableInfo): Drop the `Idx' property from this
5227 class, as this is not taking into account the indexes for
5228 temporaries tat we generate during the execution, getting the
5231 * class.cs: First emit class initializers, then call the parent
5234 * expression.cs (Binary): Fix opcode emision.
5235 (UnaryMutator.EmitCode): Support checked code generation
5237 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
5238 matches for events for both the Static and Instance scans,
5239 pointing to the same element. Fix that.
5241 2002-03-14 Miguel de Icaza <miguel@ximian.com>
5243 * rootcontext.cs (ResolveTree): Always set the
5244 interface_resolve_order, because nested interfaces will be calling
5247 * class.cs (GetInterfaceOrClass): Track the same resolution
5248 process used by TypeManager.LookupType. This fixes the nested
5249 type lookups in class declarations (separate path from
5252 (TypeContainer.DefineType): Also define nested interfaces.
5253 (TypeContainer.RegisterOrder): New public function used to
5254 register the order in which child interfaces need to be closed.
5256 Nested interfaces need to be closed after their parents have been
5259 * interface.cs (InterfaceAttr): Put all the logic for computing
5260 the interface attribute here.
5262 (DefineInterface): Register our interface order with the
5263 RootContext or with the TypeContainer depending on the case.
5265 2002-03-12 Miguel de Icaza <miguel@ximian.com>
5267 * cs-parser.jay: rework foreach statement to work with the new
5268 changes to the policy on SimpleNames.
5270 * report.cs: support Stacktrace on warnings as well.
5272 * makefile: drop --unsafe and /unsafe from the compile.
5274 2002-03-13 Ravi Pratap <ravi@ximian.com>
5276 * ecore.cs (StandardConversionExists): Modify to take an Expression
5277 as the first parameter. Ensure we do null -> reference type conversion
5280 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
5281 temporary Expression objects.
5283 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
5285 * interface.cs: workaround bug in method overloading resolution
5286 (there is already a bugzilla bug for it).
5288 2002-03-12 Miguel de Icaza <miguel@ximian.com>
5290 We could also solve this problem by having a separate path for
5291 performing type lookups, instead of DoResolve, we could have a
5292 ResolveType entry point, and only participating pieces of the
5293 production (simplename, deref, array) would implement this.
5295 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
5296 signal SimpleName to only resolve type names and not attempt to
5297 resolve anything else.
5299 * expression.cs (Cast): Set the flag.
5301 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
5303 * class.cs: Only report 108 if there is no `new' modifier.
5305 * cs-parser.jay: rework foreach statement to work with the new
5306 changes to the policy on SimpleNames.
5308 * report.cs: support Stacktrace on warnings as well.
5310 * makefile: drop --unsafe and /unsafe from the compile.
5312 2002-03-11 Miguel de Icaza <miguel@ximian.com>
5314 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
5315 lookups here, instead of doing that at parse time. This means
5316 that our grammar will not introduce `LocalVariableReferences' as
5317 expressions at this point. That solves the problem of code like
5325 This is only half the fix. The full fix requires parameters to
5326 also be handled in this way.
5328 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
5329 makes the use more obvious of the DeclSpace. The
5330 ec.TypeContainer.TypeBuilder is now only used to pull the
5333 My theory is that I can get rid of the TypeBuilder completely from
5334 the EmitContext, and have typecasts where it is used (from
5335 DeclSpace to where it matters).
5337 The only pending problem is that the code that implements Aliases
5338 is on TypeContainer, and probably should go in DeclSpace.
5340 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
5341 lookups here, instead of doing that at parse time. This means
5342 that our grammar will not introduce `LocalVariableReferences' as
5343 expressions at this point. That solves the problem of code like
5351 This is only half the fix. The full fix requires parameters to
5352 also be handled in this way.
5354 * class.cs (Property.DefineMethod): When implementing an interface
5355 method, set newslot, when implementing an abstract method, do not
5356 set the flag (before we tried never setting it, or always setting
5357 it, which is the difference).
5358 (Indexer.DefineMethod): same.
5359 (Method.DefineMethod): same.
5361 * ecore.cs: Only set the status used flag if we get back a Field.
5363 * attribute.cs: Temporary hack, so Paolo can keep working.
5365 2002-03-08 Ravi Pratap <ravi@ximian.com>
5367 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
5368 the unmanaged type in the case we have a MarshalAs attribute.
5370 (Resolve): Handle the case when we are parsing the special MarshalAs
5371 attribute [we need to store the unmanaged type to use later]
5373 * typemanager.cs (marshal_as_attr_type): Built in type for the
5374 MarshalAs Attribute.
5376 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
5377 on parameters and accordingly set the marshalling info.
5379 2002-03-09 Miguel de Icaza <miguel@ximian.com>
5381 * class.cs: Optimizing slightly by removing redundant code after
5382 we switched to the `NoTypes' return value.
5383 (Property.DefineMethod): use NoTypes here too.
5385 This fixes the bug I introduced in my last batch of changes.
5387 2002-03-05 Ravi Pratap <ravi@ximian.com>
5389 * tree.cs (RecordEnum): Add. We now keep track of enums too.
5391 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
5392 Enums since those are types too.
5394 * cs-parser.jay (enum_declaration): Record enums as we parse them.
5396 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
5397 thanks to a call during the lookup process.
5399 2002-03-07 Miguel de Icaza <miguel@ximian.com>
5401 * statement.cs (Foreach): Lots of work to accomodate a particular
5402 kind of foreach statement that I had not kept in mind. It is
5403 possible to have foreachs on classes that provide a GetEnumerator
5404 method that return objects that implement the "pattern" for using
5405 a foreach, there is no need to support GetEnumerator
5408 This is needed to compile nant.
5410 * decl.cs: Only report 114 if the member is not `Finalize' and if
5411 the warning level is at least 2.
5413 * class.cs: Moved the compare function from Method to
5416 (MethodSignature.InheritableMemberSignatureCompare): Add new
5417 filter function that is used to extract inheritable methods from a
5420 (Method.Define): Use the new `inheritable_method_signature_filter'
5423 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
5426 2002-03-06 Miguel de Icaza <miguel@ximian.com>
5428 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
5430 * cs-parser.jay: Add opt_semicolon to the interface declaration.
5432 * expression.cs: Pass location information to
5433 ConvertImplicitStandard.
5435 * class.cs: Added debugging code to track return values from
5438 2002-03-05 Miguel de Icaza <miguel@ximian.com>
5440 * expression.cs (Is.DoResolve): If either side of the `is' is an
5441 interface, do not flag the warning.
5443 * ecore.cs (ImplicitReferenceConversion): We need a separate test
5446 * report.cs: Allow for --fatal to be used with --probe.
5448 * typemanager.cs (NoTypes): Move the definition for the empty Type
5451 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
5453 (TypeContainer.DefineProxy): New function used to proxy to parent
5454 implementations when implementing interfaces.
5455 (TypeContainer.ParentImplements): used to lookup if our parent
5456 implements a public function that is required by an interface.
5457 (TypeContainer.VerifyPendingMethods): Hook this up.
5459 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
5460 `modules' and `assemblies' arraylists into arrays. We only grow
5461 these are the very early start up of the program, so this improves
5462 the speedof LookupType (nicely measured).
5464 * expression.cs (MakeByteBlob): Replaced unsafe code with
5465 BitConverter, as suggested by Paolo.
5467 * cfold.cs (ConstantFold.Binary): Special case: perform constant
5468 folding of string concatenation, but if either side is a string,
5469 and the other is not, then return null, and let the runtime use
5470 the concatenation on the string plus the object (using
5473 2002-03-04 Miguel de Icaza <miguel@ximian.com>
5475 Constant Folding has been implemented now.

5478 the error instead on types that are not supported in one's
5481 * constant.cs (Constant and all children): New set of functions to
5482 perform implict and explicit conversions.
5484 * ecore.cs (EnumConstant): Implement the new functions to perform
5485 conversion by proxying to the child expression.
5487 * codegen.cs: (ConstantCheckState): Constant evaluation has its
5488 own separate setting that can not be turned off from the command
5489 line using --unchecked or --checked and is only controlled using
5490 the checked/unchecked statements and expressions. This setting is
5491 used by the constant folder to flag errors.
5493 * expression.cs (CheckedExpr, UncheckedExpr): Set the
5494 ConstantCheckState as well.
5496 During Resolve, they also have to flag the state, because the
5497 constant folder runs completely in the Resolve phase.
5499 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
5502 2002-03-01 Miguel de Icaza <miguel@ximian.com>
5504 * cfold.cs: New file, this file contains the constant folder.
5506 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
5507 argument to track whether we are using the resulting address to
5508 load or store a value and provide better error messages.
5510 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
5511 new AddressOf arguments.
5513 * statement.cs (Foreach.EmitCollectionForeach): Update
5515 * expression.cs (Argument.Emit): Call AddressOf with proper
5516 arguments to track usage.

5524 * cs-parser.jay (member_access): Change the case for pre-defined types
5525 to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
5528 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
5531 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
5532 essentially like methods and apply attributes like MethodImplOptions to them too.
5534 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
5537 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
5538 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
5541 * Update code everywhere accordingly.
5543 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
5545 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
5547 2002-02-28 Ravi Pratap <ravi@ximian.com>
5549 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
5550 try performing lookups against those instead of jumping straight into using
5551 the 'using' clauses.
5553 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
5555 (LookupType): Perform lookups in implicit parents too.
5557 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
5558 sequence as RootContext.LookupType.
5560 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
5561 the various cases of namespace lookups into this method.
5563 2002-03-01 Miguel de Icaza <miguel@ximian.com>
5565 * cs-parser.jay: Add support for [Attribute ()] (empty arguments
5566 in positional arguments)
5568 * class.cs (Operator): Update the AllowedModifiers to contain

5583 2002-02-26 Miguel de Icaza <miguel@ximian.com>
5585 * expression.cs: Special case the `null' object when trying to
5586 auto-compute the type, as anything can be explicitly converted to
5589 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
5590 spotting this Paolo.
5592 (Expression.ImplicitNumericConversion): Perform comparissions of
5593 the type using the underlying type in the case of an enumeration
5594 rather than using the enumeration type for the compare.
5596 Cope with the underlying == type case, which is not possible to
5599 (Expression.ConvertNumericExplicit): Perform comparissions of
5600 the type using the underlying type in the case of an enumeration
5601 rather than using the enumeration type for the compare.
5603 * driver.cs: If the user does not supply an extension, assume .exe
5605 * cs-parser.jay (if_statement): Rewrote so that we can track the
5606 location for the if statement.
5608 * expression.cs (Binary.ConstantFold): Only concat strings when
5609 the operation is "+", not everything ;-)
5611 * statement.cs (Statement.EmitBoolExpression): Take a location
5613 (If, While, Do): Track location.
5615 * expression.cs (Binary.ResolveOperator): In the object + string
5616 case, I was missing a call to ConvertImplicit
5618 2002-02-25 Ravi Pratap <ravi@ximian.com>
5620 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
5621 Location arguments. Ensure we use RootContext.LookupType to do our work
5622 and not try to do a direct Type.GetType and ModuleBuilder.GetType
5624 * interface.cs (PopulateMethod): Handle the type of the parameter being
5627 * expression.cs (Invocation.BetterFunction): Handle the case when we
5628 have a params method with no fixed arguments and a call is made with no

5642 (GetParameterByName): Fix bug where we were not looking up array
5643 paramters if they were the only present (thanks Paolo!).
5644 (GetParameterInfo): We only have an empty set of types if both
5645 fixed and array are set to null.
5646 (GetParameterInfo-idx): Handle FixedParameter == null
5648 * cs-parser.jay: Handle the case where there is no catch
5649 statements (missing null test).

5653 * driver.cs (MainDriver): Be conservative on our command line
5656 Catch DirectoryNotFoundException when calling GetFiles.
5658 (SplitPathAndPattern): Used to split the input specification into

5671 * expression.cs (Binary.ResolveOperator): Remove redundant
5672 MemberLookup pn parent type.
5673 Optimize union call, we do not need a union if the types are the same.
5674 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
5677 Specialize the use of MemberLookup everywhere, instead of using
5678 the default settings.
5680 (StackAlloc): Implement stackalloc keyword.
5682 * cs-parser.jay: Add rule to parse stackalloc.
5684 * driver.cs: Handle /h, /help, /?

5702 * statement.cs (Fixed): Implement fixed statement for arrays, we
5703 are missing one more case before we are done.
5705 * expression.cs (Indirection): Implement EmitAssign and set the
5706 ExprClass to Variable. This allows pointer dereferences to be
5707 treated as variables, and to have values assigned to them.
5709 * ecore.cs (Expression.StoreFromPtr): New utility function to
5710 store values dereferencing.
5712 2002-02-20 Ravi Pratap <ravi@ximian.com>
5714 * expression.cs (Binary.ResolveOperator): Ensure that we are
5715 not trying to operate on a void type - this fixes the reported
5718 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
5719 the parent implementation is sealed.
5721 * ../errors/cs0239.cs : Add.
5723 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
5725 * typemanager.cs (unverifiable_code_type): Corresponds to
5726 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
5727 which have unsafe code in them.
5729 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
5732 2002-02-19 Miguel de Icaza <miguel@ximian.com>

5757 statement for the &x case.
5759 2002-02-14 Miguel de Icaza <miguel@ximian.com>
5761 * class.cs (Property.Define, Method.Define): Remove newslot when
5764 * modifiers.cs: My use of NewSlot when `Abstract' was set was
5765 wrong. NewSlot should only be used if the `new' keyword is present.
5767 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
5768 locating our system dir. Sorry about this.
5770 2002-02-13 Miguel de Icaza <miguel@ximian.com>
5772 * driver.cs (GetSystemDir): Compute correctly the location of our
5773 system assemblies. I was using the compiler directory instead of
5774 the library directory.
5776 2002-02-13 Ravi Pratap <ravi@ximian.com>
5778 * expression.cs (BetterFunction): Put back in what Miguel commented out
5779 since it is the correct fix. The problem is elsewhere ;-)
5781 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
5782 parameters of the parms method are themselves compatible or not !
5784 (StandardConversionExists): Fix very dangerous bug where we were forgetting
5785 to check that a class implements an interface before saying that an implicit
5786 conversion was allowed. Use ImplementsInterface to do the checking.
5788 2002-02-13 Miguel de Icaza <miguel@ximian.com>
5790 * class.cs (Method.Define): Track whether we are an explicit
5791 implementation or not. And only call DefineMethodOverride if we
5792 are an explicit implementation.
5794 (Property.DefineMethod): Ditto.
5796 2002-02-11 Ravi Pratap <ravi@ximian.com>
5798 * expression.cs (BetterFunction): Catch hideous bug which was
5799 preventing us from detecting ambiguous calls due to implicit casts i.e
5802 2002-01-29 Miguel de Icaza <miguel@ximian.com>
5804 * support.cs (Pair): Remove un-needed method. I figured why I was
5805 getting the error in cs-parser.jay, the variable in a foreach loop
5806 is readonly, and the compiler does not really treat this as a variable.
5808 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
5809 instead of EQUALS in grammar.
5811 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
5813 * expression.cs (Unary.DoResolve): Check whether the argument is
5816 2002-01-28 Miguel de Icaza <miguel@ximian.com>
5818 * support.cs: Api for Pair to set a value. Despite the fact that
5819 the variables are public the MS C# compiler refuses to compile
5820 code that accesses the field if the variable is part of a foreach
5823 * statement.cs (Fixed): Begin implementation of the fixed
5826 (Block.AddVariable): Return the VariableInfo on success and null
5827 on failure instead of true/false.
5829 * cs-parser.jay (foreach): Catch errors on variables already
5830 defined (we were ignoring this value before) and properly unwind
5833 (fixed_statement): grammar for the fixed statement.

5857 (Expression.LoadFromPtr): Factor the load-indirect code in this
5858 function. This was duplicated in UnboxCast and ParameterReference
5860 2002-01-24 Miguel de Icaza <miguel@ximian.com>
5862 * expression.cs (ComposedCast): report an error if a pointer cast
5863 is used in a safe region.
5865 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
5866 pointer type casts in unsafe context.

5875 not virtual. Fixes bug in MIS
5877 * statement.cs (Do.Emit, While.Emit, For.Emit,
5878 Statement.EmitBoolExpression): Add support to Do and While to
5879 propagate infinite loop as `I do return' semantics.
5881 Improve the For case to also test for boolean constants.
5883 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
5884 to the list of attributes we can add.
5886 Remove `EmitContext' argument.
5888 * class.cs (Method.Define): Apply parameter attributes.
5889 (Constructor.Define): Apply parameter attributes.
5890 (MethodCore.LabelParameters): Move here the core of labeling
5893 * support.cs (ReflectionParameters.ParameterModifier,
5894 InternalParameters.ParameterModifier): Use IsByRef on the type and
5895 only return the OUT bit for these parameters instead of in/out/ref
5898 This is because I miss-understood things. The ParameterInfo.IsIn
5899 and IsOut represent whether the parameter has the [In] and [Out]
5902 2002-01-22 Miguel de Icaza <miguel@ximian.com>
5904 * ecore.cs (FieldExpr.Emit): Release temporaries.

5908 * codegen.cs (EmitContext.GetTemporaryStorage,
5909 EmitContext.FreeTemporaryStorage): Rework the way we deal with

5913 2002-01-21 Miguel de Icaza <miguel@ximian.com>
5915 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
5916 need to make a copy of the variable to generate verifiable code.
5918 2002-01-19 Miguel de Icaza <miguel@ximian.com>
5920 * driver.cs: Compute dynamically the system directory.
5922 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
5923 Slower, but more generally useful. Used by the abstract
5924 registering implementation.
5926 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
5927 the rules for the special rule on Type/instances. First check if
5928 we have the same name, and if so, try that special static path
5929 rather than the instance path.
5931 2002-01-18 Miguel de Icaza <miguel@ximian.com>
5933 * cs-parser.jay: Emit 642 (warning: possible empty statement) for

5941 * typemanager.cs (IndexerPropetyName): Ravi never tested this
5944 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
5945 fix, we were returning too early, so we were not registering
5946 pending methods from abstract classes.
5948 Do not register pending methods if the class is abstract.
5950 * expression.cs (Conditional.DoResolve): Report circular implicit
5951 conversions when we neecd to compute it for conditional
5954 (Is.DoResolve): If the expression is always of the provided type,
5955 flag warning 183. If the expression can not ever be of the
5956 provided type flag warning 184.
5958 * class.cs: Catch 169 as well.
5960 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and

5969 * interface.cs: (PopulateMethod): Check for pointers being defined
5970 only if the unsafe context is active.
5971 (PopulateProperty): ditto.
5972 (PopulateIndexer): ditto.
5974 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be

5983 hashtable if there are classes or structs defined.
5985 * expression.cs (LocalVariableReference.DoResolve): Simplify this
5986 code, as the constant resolution moved.
5988 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
5989 the metadata, so we can flag error 133.
5991 * decl.cs (MemberCore.UnsafeOK): New function to test that a
5992 pointer is being declared in an unsafe context.
5994 2002-01-16 Miguel de Icaza <miguel@ximian.com>
5996 * modifiers.cs (Modifiers.Check): Require a Location argument.
5997 Report error 227 for Unsafe use.
5999 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
6001 * statement.cs (For.Emit): If the test is null, then report that
6002 we do `return', as we wont reach anything afterwards.
6004 (Switch.SwitchGoverningType): Track the expression that matched
6007 * driver.cs: Allow negative numbers as an error code to flag.
6009 * cs-parser.jay: Handle 1551.

6029 access not allowed in static code)
6031 2002-01-11 Ravi Pratap <ravi@ximian.com>
6033 * typemanager.cs (IsPointerType): Utility method which we are going
6036 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
6037 the object type, so we take care of that.
6039 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
6041 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
6042 added to non-params parameters :-)
6044 * typemanager.cs (CSharpName): Include 'void' type too.
6046 (void_ptr_type): Include in the set of core types.
6048 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
6051 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
6054 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
6055 completely forgotten about it.
6057 2002-01-10 Ravi Pratap <ravi@ximian.com>
6059 * cs-parser.jay (pointer_type): Add. This begins our implementation
6060 of parsing rules for unsafe code.
6062 (unsafe_statement): Implement.
6064 (embedded_statement): Modify to include the above.
6066 * statement.cs (Unsafe): Implement new class for unsafe blocks.
6068 * codegen.cs (EmitContext.InUnsafe): Add. This determines
6069 if the current context is an unsafe one.
6071 * cs-parser.jay (local_variable_pointer_type): Since local variable types
6072 are handled differently, we need separate rules for them.
6074 (local_variable_declaration): Update to use local_variable_pointer_type
6075 to allow variable declarations of unmanaged pointer types.
6077 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
6080 * ../errors/cs0214.cs : Add.
6082 2002-01-16 Nick Drochak <ndrochak@gol.com>

6100 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
6103 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
6104 this routine and will wrap the call in a try/catch block. Deal
6107 2002-01-11 Miguel de Icaza <miguel@ximian.com>
6109 * ecore.cs (Expression.MemberLookup): instead of taking a
6110 parameter `same_type' that was used to tell whether we could
6111 access private members we compute our containing type from the
6114 (FieldExpr): Added partial support for volatile fields. This does
6115 not work for volatile fields exposed from assemblies, as I can not
6116 figure out how to extract the modreq from it.
6118 Updated all the source files to use this.
6120 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
6121 because it is referenced by MemberLookup very often.
6123 2002-01-09 Ravi Pratap <ravi@ximian.com>
6125 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
6126 TypeBuilder.GetCustomAttributes to retrieve what we need.
6128 Get rid of redundant default_member_attr_type as this is the same as
6129 default_member_type which already exists.
6131 * interface.cs, attribute.cs : Update accordingly.
6133 2002-01-08 Miguel de Icaza <miguel@ximian.com>
6135 * typemanager.cs: Enable IndexerPropertyName again. It does not
6136 work for TYpeBuilders though. Ravi, can you please fix this?
6138 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
6140 * expression.cs (Argument.Emit): Handle the case of ref objects
6141 being passed to ref functions;
6143 (ParameterReference.EmitLoad): Loads the content of the pointer
6144 without dereferencing.
6146 2002-01-07 Miguel de Icaza <miguel@ximian.com>
6148 * cs-tokenizer.cs: Implemented the pre-processing expressions.
6150 2002-01-08 Ravi Pratap <ravi@ximian.com>
6152 * class.cs (Indexer.DefineMethod): Incorporate the interface
6153 type in the name of the method if we are doing explicit interface
6156 * expression.cs (ConversionExists): Remove as it is completely obsolete.
6158 (BetterConversion): Fix extremely trivial bug where we were referring to
6159 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
6162 * ../errors/bug16.cs : Add although we have fixed it.
6164 2002-01-07 Miguel de Icaza <miguel@ximian.com>
6166 * expression.cs (BaseIndexer): Begin implementation.
6168 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
6170 * cs-parser.jay (indexer_declarator): Use qualified_identifier
6171 production directly to remove a shift/reduce, and implement
6172 explicit interface implementation.
6174 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
6175 after a floating point suffix.
6177 * expression.cs (DoNumericPromotions): Improved the conversion for
6178 uint/uint. If we have a constant, we avoid doing a typecast to a
6181 * class.cs (Indexer): Implement explicit interface implementation
6184 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
6186 * class.cs: make the default instance constructor public and hidebysig.
6188 2001-01-03 Ravi Pratap <ravi@ximian.com>
6190 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
6191 so we can call it from elsewhere.
6193 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
6194 we emit it internally if the class has a defined indexer; otherwise the user
6195 emits it by decorating the class definition with the DefaultMemberAttribute.
6197 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
6198 attribute is not used on a type which defines an indexer.
6200 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
6201 character when we skip whitespace.
6203 * ../errors/cs0646.cs : Add.
6205 2002-01-03 Miguel de Icaza <miguel@ximian.com>
6207 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
6210 * makefile: Add practical target `mcs3.exe' which builds the third
6211 generation compiler.
6213 * expression.cs (New): Fix structures constructor calling.
6215 * class.cs (Property, Method, Indexer): Emit Final flag on the
6216 method if we are an interface implementation and we are not
6219 * ecore.cs (PropertyExpr): New public field `IsBase', tells
6220 whether this property is referencing a `base' method.
6222 * expression.cs (Invocation.EmitCall): take an extra argument:
6223 is_base, this is used to determine whether the `call' or
6224 `callvirt' opcode should be used.
6227 * delegate.cs: update EmitCall.
6229 * class.cs (Method.Define): Set NewSlot for the cases where we are
6230 not implementing an interface method.
6232 (Property.Define): ditto.
6234 2002-01-02 Miguel de Icaza <miguel@ximian.com>
6236 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
6237 'r'. Allows mcs to parse itself fully.
6239 2002-01-02 Ravi Pratap <ravi@ximian.com>
6241 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
6242 of the number of initializers that require the InitializeArray method.
6244 (CheckIndices): Store the Expression in all cases - not the plain value. Also
6245 update the above field where necessary.
6247 (MakeByteBlob): Update accordingly.
6249 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
6252 (EmitDynamicInitializers): Update in accordance with the new optimization.
6254 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
6255 same OpCode applies.
6257 * cs-parser.jay : Fix some glaring errors I introduced.
6259 2002-01-01 Ravi Pratap <ravi@ximian.com>
6261 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
6262 so that we can check for name clashes there too.
6264 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
6265 for interface indexers.
6267 * interfaces.cs (Define): Emit the default member attribute.
6269 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
6270 variable was being referred to while setting the value ;-)
6272 2002-01-01 Miguel de Icaza <miguel@ximian.com>
6274 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
6275 byte-by-byte information when we know the data is zero.
6277 Make the block always a multiple of 4, because
6278 DefineInitializedData has a bug.
6280 * assign.cs: Fix, we should assign from the temporary, not from
6283 * expression.cs (MakeByteBlob): Fix my incorrect code.
6285 2001-12-31 Miguel de Icaza <miguel@ximian.com>
6287 * typemanager.cs (EnumToUnderlying): This function is used to get
6288 the underlying type from an enumeration, because it does not
6291 * constant.cs: Use the I4_S form for values between -128 and 127.
6293 * statement.cs (Block.LookupLabel): Looks up a label.
6294 (Block): Drop support for labeled blocks.
6296 (LabeledStatement): New kind of statement that represents a label
6299 (Goto): Finally implement this bad boy.
6301 * cs-parser.jay: Update to reflect new mechanism to implement
6304 2001-12-30 Miguel de Icaza <miguel@ximian.com>
6306 * codegen.cs (EmitContext.This): a codegen property that keeps the
6307 a single instance of this instead of creating many different this
6310 * delegate.cs (Delegate.DoResolve): Update to use the property;
6312 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
6314 * expression.cs (BaseAccess.DoResolve): Ditto.
6316 2001-12-29 Ravi Pratap <ravi@ximian.com>
6318 * typemanager.cs (methodimpl_attr_type): Add to hold the type
6319 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
6321 (InitCoreTypes): Update accordingly.
6323 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
6324 so we can quickly store the state.
6326 (ApplyAttributes): Set the correct implementation flags
6327 for InternalCall methods.
6329 2001-12-29 Miguel de Icaza <miguel@ximian.com>
6331 * expression.cs (EmitCall): if a method is not virtual, then do
6332 not use callvirt on it.
6334 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
6335 user defined stuff) requires the use of stobj, which takes an
6336 address on the stack instead of an array and an index. So emit
6337 the Ldelema operation for it.
6339 (EmitStoreOpcode): Use stobj for valuetypes.
6341 (UnaryMutator.EmitCode): Use the right 1 value depending on
6342 whether we are dealing with int64/uint64, float or doubles.
6344 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
6345 constructors that I implemented last night.
6347 (Constructor.IsDefault): Fix to work properly for static
6350 * cs-parser.jay (CheckDef): report method signature errors.
6351 Update error number 103 to be 132.
6353 * decl.cs: New AdditionResult enumeration value: MethodExists.
6354 Although we do this check for methods later on in the semantic
6355 analysis, catching repeated default constructors is so easy that
6356 we catch these here.
6358 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
6361 (ParameterReference.EmitAssign, Emit): handle
6364 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
6365 (ArrayAccess.EmitStoreOpcode): ditto.
6367 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
6369 * expression.cs (MakeByteBlob): Complete all the missing types
6370 (uint, short, ushort, byte, sbyte)
6372 * class.cs: Only init instance field initializers on instance
6375 Rename `constructors' to instance_constructors.
6377 (TypeContainer.AddConstructor): Only add constructors to the list
6378 if it is not static.
6380 Make sure that we handle default_static_constructor independently
6381 everywhere where we handle instance_constructors
6383 2001-12-28 Miguel de Icaza <miguel@ximian.com>
6385 * class.cs: Do not lookup or create a base initializer for a
6388 (ConstructorInitializer.Resolve): use the proper type to lookup
6391 * cs-parser.jay: Report error 1585 (modifiers between type and name).
6393 * enum.cs, interface.cs: Remove CloseType, this is taken care by
6396 * decl.cs: CloseType is now an virtual method, the default
6397 implementation just closes this type.
6399 2001-12-28 Ravi Pratap <ravi@ximian.com>
6401 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
6402 to PreserveSig by default. Also emit HideBySig on such methods.
6404 Basically, set the defaults to standard values.
6406 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
6407 argument, if candidate is better, it can't be worse than the best !
6409 (Invocation): Re-write bits to differentiate between methods being
6410 applicable in their expanded form and their normal form - for params
6413 Get rid of use_standard everywhere as only standard conversions are allowed
6414 in overload resolution.
6416 More spec conformance.
6418 2001-12-27 Miguel de Icaza <miguel@ximian.com>
6420 * driver.cs: Add --timestamp, to see where the compiler spends
6423 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
6424 `this' in static code.
6426 (SimpleName.DoResolve): Implement in terms of a helper function
6427 that allows static-references to be passed upstream to
6430 (Expression.ResolveWithSimpleName): Resolve specially simple
6431 names when called by MemberAccess to implement the special
6434 (Expression.ImplicitReferenceConversion): Handle conversions from
6435 Null to reference types before others, as Null's type is
6438 * expression.cs (Invocation.EmitCall): Handle the special case of
6439 calling methods declared on a reference type from a ValueType
6440 (Base classes System.Object and System.Enum)
6442 (MemberAccess.Resolve): Only perform lookups on Enumerations if
6443 the left hand side is a TypeExpr, not on every enumeration.
6445 (Binary.Resolve): If types are reference types, then do a cast to
6446 object on operators != and == of both arguments.
6448 * typemanager.cs (FindMembers): Extract instance and static
6449 members if requested.
6451 * interface.cs (PopulateProperty): Use void_type instead of null
6452 as the return type for the setter method.
6454 (PopulateIndexer): ditto.
6456 2001-12-27 Ravi Pratap <ravi@ximian.com>
6458 * support.cs (ReflectionParameters): Fix minor bug where we
6459 were examining the wrong parameter for the ParamArray attribute.
6461 Cope with requests for the type of the parameter at position
6462 greater than the params parameter's. We now return the element
6463 type of the params array as that makes more sense.
6465 * expression.cs (Invocation.IsParamsMethodApplicable): Update
6466 accordingly as we no longer have to extract the element type
6469 (Invocation.OverloadResolve): Update.
6471 2001-12-27 Miguel de Icaza <miguel@ximian.com>
6473 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
6474 against IEnumerator, test whether the return value is a descendant
6475 of the IEnumerator interface.
6477 * class.cs (Indexer.Define): Use an auxiliary method to implement
6478 the other bits of the method definition. Begin support for
6479 explicit interface implementation.
6481 (Property.DefineMethod): Use TypeManager.void_type instead of null
6482 for an empty return value.
6484 2001-12-26 Miguel de Icaza <miguel@ximian.com>
6486 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
6487 dealing with a FieldExpr which is composed of a FieldBuilder, in
6488 the code path we did extract the constant, but we should have
6489 obtained the underlying value to be able to cast it (otherwise we
6490 end up in an infinite loop, this is what Ravi was running into).
6492 (ArrayCreation.UpdateIndices): Arrays might be empty.
6494 (MemberAccess.ResolveMemberAccess): Add support for section
6495 14.5.4.1 that deals with the special case of E.I when E is a type
6496 and something else, that I can be a reference to a static member.
6498 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
6499 handle a particular array type to create byte blobs, it is just
6500 something we dont generate byteblobs for.
6502 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
6505 * location.cs (Push): remove the key from the hashtable that we
6506 are about to add. This happens for empty files.
6508 * driver.cs: Dispose files after we have parsed them.
6510 (tokenize): new function that only runs the tokenizer on its
6511 input, for speed testing.
6513 2001-12-26 Ravi Pratap <ravi@ximian.com>
6515 * class.cs (Event.Define): Define the private field only if there
6516 are no accessors defined.
6518 * expression.cs (ResolveMemberAccess): If there is no associated
6519 field with the event, that means we have an event defined with its
6520 own accessors and we should flag error cs0070 since transforming
6521 ourselves into a field is not valid in that case.
6523 * ecore.cs (SimpleName.DoResolve): Same as above.
6525 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
6526 and charset to sane values.
6528 2001-12-25 Ravi Pratap <ravi@ximian.com>
6530 * assign.cs (DoResolve): Perform check on events only if they
6531 are being accessed outside the declaring type.
6533 * cs-parser.jay (event_declarations): Update rules to correctly
6534 set the type of the implicit parameter etc.
6536 (add_accessor, remove_accessor): Set current local parameters.
6538 * expression.cs (Binary): For delegate addition and subtraction,
6539 cast the return value from the method into the appropriate delegate
6542 2001-12-24 Ravi Pratap <ravi@ximian.com>
6544 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
6545 of these as the workaround is unnecessary.
6547 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
6548 delegate data - none of that is needed at all.
6550 Re-write bits to extract the instance expression and the delegate method
6553 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
6556 * attribute.cs (ApplyAttributes): New method to take care of common tasks
6557 of attaching attributes instead of duplicating code everywhere.
6559 * everywhere : Update code to do attribute emission using the above method.
6561 2001-12-23 Miguel de Icaza <miguel@ximian.com>
6563 * expression.cs (IsParamsMethodApplicable): if there are not
6564 parameters, return immediately.
6566 * ecore.cs: The 0 literal can be implicity converted to an enum
6569 (SimpleName.DoResolve): First lookup the type, then lookup the
6572 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
6573 want to get its address. If the InstanceExpression is not
6574 addressable, store the result in a temporary variable, then get
6577 * codegen.cs: Only display 219 errors on warning level or above.
6579 * expression.cs (ArrayAccess): Make it implement the
6580 IMemoryLocation interface.
6582 (Binary.DoResolve): handle the operator == (object a, object b)
6583 and operator != (object a, object b) without incurring into a
6584 BoxedCast (because 5 != o should never be performed).
6586 Handle binary enumerator operators.
6588 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
6589 value type, otherwise use Ldelem_ref.
6591 Use precomputed names;
6593 (AddressOf): Implement address of
6595 * cs-parser.jay (labeled_statement): Fix recursive block
6596 addition by reworking the production.
6598 * expression.cs (New.DoEmit): New has a special case:
6600 If we are dealing with a ValueType, we have a few
6601 situations to deal with:
6603 * The target of New is a ValueType variable, that is
6604 easy, we just pass this as the variable reference
6606 * The target of New is being passed as an argument,
6607 to a boxing operation or a function that takes a
6610 In this case, we need to create a temporary variable
6611 that is the argument of New.
6614 2001-12-23 Ravi Pratap <ravi@ximian.com>
6616 * rootcontext.cs (LookupType): Check that current_type is not null before
6617 going about looking at nested types.
6619 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
6620 not implement the IAssignMethod interface any more.
6622 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
6623 where we tranform them into FieldExprs if they are being resolved from within
6626 * ecore.cs (SimpleName.DoResolve): Do the same here.
6628 * assign.cs (DoResolve, Emit): Clean up code considerably.
6630 * ../errors/bug10.cs : Add.
6632 * ../errors/cs0070.cs : Add.
6634 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
6636 * assign.cs : Get rid of EventIsLocal everywhere.
6638 2001-12-23 Miguel de Icaza <miguel@ximian.com>
6640 * ecore.cs (ConvertIntLiteral): finished the implementation.
6642 * statement.cs (SwitchLabel): Convert the value we are using as a
6643 key before looking up the table.
6645 2001-12-22 Miguel de Icaza <miguel@ximian.com>
6647 * codegen.cs (EmitTopBlock): Require a Location argument now.
6649 * cs-parser.jay (constructor_declarator): We need to setup
6650 current_local_parameters before we parse the
6651 opt_constructor_initializer, to allow the variables to be bound
6652 to the constructor arguments.
6654 * rootcontext.cs (LookupType): First lookup nested classes in our
6655 class and our parents before we go looking outside our class.
6657 * expression.cs (ConstantFold): Extract/debox the values at the
6660 * rootcontext.cs (EmitCode): Resolve the constants first before we
6661 resolve the types. This is not really needed, but it helps debugging.
6663 * statement.cs: report location.
6665 * cs-parser.jay: pass location to throw statement.
6667 * driver.cs: Small bug fix.
6669 * report.cs: Updated format to be 4-zero filled digits.
6671 2001-12-22 Ravi Pratap <ravi@ximian.com>
6673 * expression.cs (CheckIndices): Fix minor bug where the wrong
6674 variable was being referred to ;-)
6676 (DoEmit): Do not call EmitStaticInitializers when the
6677 underlying type is System.Object.
6679 2001-12-21 Ravi Pratap <ravi@ximian.com>
6681 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
6682 and do the usual workaround for SRE.
6684 * class.cs (MyEventBuilder.EventType): New member to get at the type
6685 of the event, quickly.
6687 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
6689 * assign.cs (Assign.DoResolve): Handle the case when the target
6690 is an EventExpr and perform the necessary checks.
6692 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
6695 (SimpleName.MemberStaticCheck): Include check for EventExpr.
6697 (EventExpr): Set the type in the constructor itself since we
6698 are meant to be born fully resolved.
6700 (EventExpr.Define): Revert code I wrote earlier.
6702 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
6703 instance expression is null. The instance expression is a This in that case
6704 or a null, depending on whether it is a static method or not.
6706 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
6707 refers to more than one method.
6709 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
6710 and accordingly flag errors.
6712 2001-12-21 Miguel de Icaza <miguel@ximian.com>
6714 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
6716 2001-12-22 Miguel de Icaza <miguel@ximian.com>
6718 * location.cs (ToString): Provide useful rutine.
6720 2001-12-21 Miguel de Icaza <miguel@ximian.com>
6722 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
6723 objects, return the actual integral boxed.
6725 * statement.cs (SwitchLabel): define an ILLabel for each
6728 (Switch.CheckSwitch): If the value is a Literal, extract
6729 the underlying literal.
6731 Also in the unused hashtable we had, add the SwitchLabel so we can
6732 quickly look this value up.
6734 * constant.cs: Implement a bunch of new constants. Rewrite
6735 Literal based on this. Made changes everywhere to adapt to this.
6737 * expression.cs (Expression.MakeByteBlob): Optimize routine by
6738 dereferencing array only once, and also copes with enumrations.
6740 bytes are two bytes wide, not one.
6742 (Cast): Perform constant conversions.
6744 * ecore.cs (TryImplicitIntConversion): Return literals instead of
6745 wrappers to the literals here.
6747 * expression.cs (DoNumericPromotions): long literals can converted
6748 to ulong implicity (this is taken care of elsewhere, but I was
6751 * ecore.cs (Expression.Literalize): Make the return type Literal,
6752 to improve type checking.
6754 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
6756 2001-12-20 Miguel de Icaza <miguel@ximian.com>
6758 * literal.cs: Revert code from ravi that checked the bounds. The
6759 bounds are sane by the definition of the type itself.
6761 * typemanager.cs: Fix implementation of ImplementsInterface. We
6762 need to actually look up in our parent hierarchy for interfaces
6765 * const.cs: Use the underlying type for enumerations
6767 * delegate.cs: Compute the basename for the delegate creation,
6768 that should fix the delegate test case, and restore the correct
6769 Type Lookup semantics in rootcontext
6771 * rootcontext.cs: Revert Ravi's last patch. The correct way of
6772 referencing a nested type with the Reflection API is using the "+"
6775 * cs-parser.jay: Do not require EOF token at the end.
6777 2001-12-20 Ravi Pratap <ravi@ximian.com>
6779 * rootcontext.cs (LookupType): Concatenate type names with
6780 a '.' instead of a '+' The test suite passes again.
6782 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
6783 field of the enumeration.
6785 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
6786 the case when the member is an EventExpr.
6788 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
6789 static has an associated instance expression.
6791 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
6793 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
6795 * class.cs (Event.Define): Register event and perform appropriate checks
6798 We define the Add and Remove methods even if the use provides none because
6799 in that case, we provide default implementations ourselves.
6801 Define a private field of the type of the event. This is done by the CSC compiler
6802 and we should be doing it too ;-)
6804 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
6805 More methods we use in code we generate.
6807 (multicast_delegate_type, delegate_type): Two separate types since the distinction
6810 (InitCoreTypes): Update accordingly for the above.
6812 * class.cs (Event.Emit): Generate code for default accessors that we provide
6814 (EmitDefaultMethod): Do the job in the above.
6816 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
6819 2001-12-20 Miguel de Icaza <miguel@ximian.com>
6821 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
6822 builders even if we were missing one.
6824 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
6825 pass the Basename as our class name instead of the Name. The
6826 basename will be correctly composed for us.
6828 * parameter.cs (Paramters): Now takes a Location argument.
6830 * decl.cs (DeclSpace.LookupType): Removed convenience function and
6831 make all the code call directly LookupType in RootContext and take
6832 this chance to pass the Location information everywhere.
6834 * Everywhere: pass Location information.
6836 2001-12-19 Miguel de Icaza <miguel@ximian.com>
6838 * class.cs (Constructor.Define): Updated way of detecting the
6839 length of the parameters.
6841 (TypeContainer.DefineType): Use basename as the type name for
6844 (TypeContainer.Define): Do not recursively define types here, as
6845 definition is taken care in order by the RootContext.
6847 * tree.cs: Keep track of namespaces in a per-file basis.
6849 * parameter.cs (Parameter.ComputeSignature): Update to use
6852 (Parameters.GetSignature): ditto.
6854 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
6855 instead of a TypeContainer.
6857 (Interface.SemanticAnalysis): Use `this' instead of our parent to
6858 resolve names. Because we need to be resolve in our context, not
6861 * driver.cs: Implement response files.
6863 * class.cs (TypeContainer.DefineType): If we are defined, do not
6866 (Event.Emit): Emit the code for add/remove handlers.
6867 (Event.Define): Save the MethodBuilders for add/remove.
6869 * typemanager.cs: Use pair here too.
6871 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
6872 DictionaryEntry requires the first argument to be non-null.
6874 (enum_declaration): Compute full name for registering the
6877 (delegate_declaration): Instead of using
6878 formal_parameter_list, use opt_formal_parameter_list as the list
6881 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
6882 (EventParsing): New property that controls whether `add' and
6883 `remove' are returned as tokens or identifiers (for events);
6885 2001-12-19 Ravi Pratap <ravi@ximian.com>
6887 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
6888 use MyEventBuilder only and let it wrap the real builder for us.
6890 (MyEventBuilder): Revamp constructor etc.
6892 Implement all operations that we perform on EventBuilder in precisely the same
6895 (FindMembers): Update to use the EventBuilder member.
6897 (Event.Emit): Update accordingly.
6899 2001-12-18 Ravi Pratap <ravi@ximian.com>
6901 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
6902 by calling the appropriate methods.
6904 (GetCustomAttributes): Make stubs as they cannot possibly do anything
6907 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
6909 2001-12-17 Ravi Pratap <ravi@ximian.com>
6911 * delegate.cs (Delegate.Populate): Check that the return type
6912 and various parameters types are indeed accessible.
6914 * class.cs (Constructor.Define): Same here.
6916 (Field.Define): Ditto.
6918 (Event.Define): Ditto.
6920 (Operator.Define): Check that the underlying Method defined itself
6921 correctly - so it's MethodBuilder should not be null.
6923 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
6924 expression happens to be null.
6926 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
6927 members but as of now we don't seem to be able to do anything really useful with it.
6929 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
6930 not the EventBuilder.
6932 2001-12-18 Miguel de Icaza <miguel@ximian.com>
6934 * cs-tokenizer.cs: Add support for defines.
6935 Add support for #if, #elif, #else, #endif
6937 (eval_var): evaluates a variable.
6938 (eval): stubbed for evaluating functions.
6940 * cs-parser.jay: Pass the defines information
6942 * driver.cs: Add --define command line option.
6944 * decl.cs: Move MemberCore here.
6946 Make it the base class for DeclSpace. This allows us to catch and
6947 report 108 and 109 for everything now.
6949 * class.cs (TypeContainer.Define): Extract all the members
6950 before populating and emit the warning 108 (new keyword required
6951 to override) instead of having each member implement this.
6953 (MemberCore.Define): New abstract method, we will be using this in
6954 the warning reporting engine in Populate.
6956 (Operator.Define): Adjust to new MemberCore protocol.
6958 * const.cs (Const): This does not derive from Expression, it is a
6959 temporary object we use to create fields, it is a MemberCore.
6961 * class.cs (Method.Define): Allow the entry point to be in a
6964 * driver.cs: Rewrite the argument handler to clean it up a bit.
6966 * rootcontext.cs: Made it just an auxiliary namespace feature by
6967 making everything static.
6969 * driver.cs: Adapt code to use RootContext type name instead of
6972 * delegate.cs: Remove RootContext argument.
6974 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
6977 * class.cs (Event.Define): The lookup can fail.
6979 * cs-tokenizer.cs: Begin implementation of pre-procesor.
6981 * expression.cs: Resolve the this instance before invoking the code.
6983 2001-12-17 Miguel de Icaza <miguel@ximian.com>
6985 * cs-parser.jay: Add a production in element_access that allows
6986 the thing to become a "type" reference. This way we can parse
6987 things like "(string [])" as a type.
6989 Note that this still does not handle the more complex rules of
6993 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
6995 * ecore.cs: (CopyNewMethods): new utility function used to
6996 assemble the list of methods from running FindMembers.
6998 (MemberLookup): Rework FindMembers so that
7000 2001-12-16 Miguel de Icaza <miguel@ximian.com>
7002 * class.cs (TypeContainer): Remove Delegates who fail to be
7005 * delegate.cs (Populate): Verify that we dont get null return
7006 values. TODO: Check for AsAccessible.
7008 * cs-parser.jay: Use basename to emit error 574 (destructor should
7009 have the same name as container class), not the full name.
7011 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
7012 possible representation.
7014 Also implements integer type suffixes U and L.
7016 2001-12-15 Miguel de Icaza <miguel@ximian.com>
7018 * expression.cs (ArrayCreation.DoResolve): We need to do the
7019 argument resolution *always*.
7021 * decl.cs: Make this hold the namespace. Hold the root context as
7023 (LookupType): Move here.
7025 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
7027 * location.cs (Row, Name): Fixed the code, it was always returning
7028 references to the first file.
7030 * interface.cs: Register properties defined through interfaces.
7032 * driver.cs: Add support for globbing on the command line
7034 * class.cs (Field): Make it derive from MemberCore as well.
7037 2001-12-15 Ravi Pratap <ravi@ximian.com>
7039 * class.cs (Event::Define): Check that the type of the event is a delegate
7040 type else flag error #66.
7042 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
7045 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
7046 values of EntryPoint, CharSet etc etc.
7048 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
7050 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
7051 be null and we should ignore this. I am not sure if this is really clean. Apparently,
7052 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
7053 which needs this to do its work.
7055 * ../errors/cs0066.cs : Add.
7057 2001-12-14 Miguel de Icaza <miguel@ximian.com>
7059 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
7062 * class.cs: (MethodSignature.MethodSignature): Removed hack that
7063 clears out the parameters field.
7064 (MemberSignatureCompare): Cleanup
7066 (MemberCore): New base class used to share code between MethodCore
7069 (RegisterRequiredImplementations) BindingFlags.Public requires
7070 either BindingFlags.Instace or Static. Use instance here.
7072 (Property): Refactored code to cope better with the full spec.
7074 * parameter.cs (GetParameterInfo): Return an empty array instead
7077 * class.cs (Property): Abstract or extern properties have no bodies.
7079 * parameter.cs (GetParameterInfo): return a zero-sized array.
7081 * class.cs (TypeContainer.MethodModifiersValid): Move all the
7082 method modifier validation to the typecontainer so we can reuse
7085 (MethodCore.ParameterTypes): return an empty sized array of types.
7087 (Property.Define): Test property modifier validity.
7089 Add tests for sealed/override too.
7091 (Method.Emit): abstract or extern methods have no bodies.
7093 2001-12-14 Ravi Pratap <ravi@ximian.com>
7095 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
7098 (Method::Define, ::Emit): Modify accordingly.
7100 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
7102 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
7104 * makefile: Pass in /unsafe.
7106 2001-12-13 Miguel de Icaza <miguel@ximian.com>
7108 * class.cs (MakeKey): Kill routine.
7110 * class.cs (TypeContainer.Define): Correctly define explicit
7111 method implementations (they require the full interface name plus
7114 * typemanager.cs: Deply the PtrHashtable here and stop using the
7115 lame keys. Things work so much better.
7117 This of course broke everyone who depended on `RegisterMethod' to
7118 do the `test for existance' test. This has to be done elsewhere.
7120 * support.cs (PtrHashtable): A hashtable that avoid comparing with
7121 the object stupid Equals method (because, that like fails all over
7122 the place). We still do not use it.
7124 * class.cs (TypeContainer.SetRequiredInterface,
7125 TypeContainer.RequireMethods): Killed these two routines and moved
7126 all the functionality to RegisterRequiredImplementations.
7128 (TypeContainer.RegisterRequiredImplementations): This routine now
7129 registers all the implementations required in an array for the
7130 interfaces and abstract methods. We use an array of structures
7131 which can be computed ahead of time to reduce memory usage and we
7132 also assume that lookups are cheap as most classes will not
7133 implement too many interfaces.
7135 We also avoid creating too many MethodSignatures.
7137 (TypeContainer.IsInterfaceMethod): Update and optionally does not
7138 clear the "pending" bit if we find that there are problems with
7141 (TypeContainer.VerifyPendingMethods): Update to report errors of
7142 methods that look like implementations but are not.
7144 (TypeContainer.Define): Add support for explicit interface method
7147 2001-12-12 Miguel de Icaza <miguel@ximian.com>
7149 * typemanager.cs: Keep track of the parameters here instead of
7150 being a feature of the TypeContainer.
7152 * class.cs: Drop the registration of parameters here, as
7153 InterfaceMethods are also interface declarations.
7155 * delegate.cs: Register methods with the TypeManager not only with
7156 the TypeContainer. This code was buggy.
7158 * interface.cs: Full registation here.
7160 2001-12-11 Miguel de Icaza <miguel@ximian.com>
7162 * expression.cs: Remove reducer for binary expressions, it can not
7165 * const.cs: Put here the code that used to go into constant.cs
7167 * constant.cs: Put here the code for constants, this is a new base
7170 * literal.cs: Make Literal derive from Constant.
7172 2001-12-09 Miguel de Icaza <miguel@ximian.com>
7174 * statement.cs (Return.Emit): Report error 157 if the user
7175 attempts to return from a finally block.
7177 (Return.Emit): Instead of emitting a return, jump to the end of
7180 * codegen.cs (EmitContext): ReturnValue, ReturnLabel: new
7181 LocalBuilder to store the result of the function. ReturnLabel is
7182 the target where we jump.
7185 2001-12-09 Radek Doulik <rodo@ximian.com>
7187 * cs-parser.jay: remember alias in current namespace

7192 * class.cs (LookupAlias): lookup alias in my_namespace
7194 * namespace.cs (UsingAlias): add alias, namespace_or_type pair to
7196 (LookupAlias): lookup alias in this and if needed in parent
7199 2001-12-08 Miguel de Icaza <miguel@ximian.com>
7203 * rootcontext.cs: (ModuleBuilder) Made static, first step into
7204 making things static. I need this to avoid passing the
7205 TypeContainer when calling ParameterType.
7207 * support.cs (InternalParameters.ParameterType): Remove ugly hack
7208 that did string manipulation to compute the type and then call
7209 GetType. Use Parameter.ParameterType instead.
7211 * cs-tokenizer.cs: Consume the suffix for floating values.
7213 * expression.cs (ParameterReference): figure out whether this is a
7214 reference parameter or not. Kill an extra variable by computing
7215 the arg_idx during emission.
7217 * parameter.cs (Parameters.GetParameterInfo): New overloaded
7218 function that returns whether a parameter is an out/ref value or not.
7220 (Parameter.ParameterType): The type of the parameter (base,
7221 without ref/out applied).
7223 (Parameter.Resolve): Perform resolution here.
7224 (Parameter.ExternalType): The full type (with ref/out applied).
7226 * statement.cs (Using.Emit, Using.EmitExpression): Implement
7227 support for expressions on the using statement.
7229 2001-12-07 Miguel de Icaza <miguel@ximian.com>
7231 * statement.cs (Using.EmitLocalVariableDecls): Split the
7232 localvariable handling of the using statement.
7234 (Block.EmitMeta): Keep track of variable count across blocks. We
7235 were reusing slots on separate branches of blocks.
7237 (Try.Emit): Emit the general code block, we were not emitting it.
7239 Check the type of the declaration to be an IDisposable or
7240 something that can be implicity converted to it.
7242 Emit conversions if required.
7244 * ecore.cs (EmptyExpression): New utility class.
7245 (Expression.ImplicitConversionExists): New utility function.
7247 2001-12-06 Miguel de Icaza <miguel@ximian.com>
7249 * statement.cs (Using): Implement.
7251 * expression.cs (LocalVariableReference): Support read only variables.
7253 * statement.cs: Remove the explicit emit for the Leave opcode.
7254 (VariableInfo): Add a readonly field.
7256 2001-12-05 Miguel de Icaza <miguel@ximian.com>
7258 * ecore.cs (ConvCast): new class used to encapsulate the various
7259 explicit integer conversions that works in both checked and
7262 (Expression.ConvertNumericExplicit): Use new ConvCast class to
7263 properly generate the overflow opcodes.
7265 2001-12-04 Miguel de Icaza <miguel@ximian.com>
7267 * statement.cs: The correct type for the EmptyExpression is the
7268 element_type, not the variable type. Ravi pointed this out.
7270 2001-12-04 Ravi Pratap <ravi@ximian.com>
7272 * class.cs (Method::Define): Handle PInvoke methods specially
7273 by using DefinePInvokeMethod instead of the usual one.
7275 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
7276 above to do the task of extracting information and defining the method.
7278 2001-12-04 Ravi Pratap <ravi@ximian.com>
7280 * expression.cs (ArrayCreation::EmitStaticInitializers): Get rid
7281 of the condition for string type.
7283 (Emit): Move that here.
7285 (ArrayCreation::CheckIndices): Keep string literals in their expression
7288 (EmitDynamicInitializers): Handle strings appropriately.
7290 2001-12-04 Miguel de Icaza <miguel@ximian.com>

7293 single pointer to the current Switch statement.
7295 * statement.cs (GotoDefault, Switch): Adjust to cleaned up
7298 2001-12-03 Miguel de Icaza <miguel@ximian.com>
7302 * statement.cs (GotoDefault), cs-parser.jay: Implement `goto
7305 (Foreach.Emit): Foreach on arrays was not setting
7306 up the loop variables (for break/continue).
7308 (GotoCase): Semi-implented.
7310 2001-12-03 Ravi Pratap <ravi@ximian.com>
7312 * attribute.cs (CheckAttribute): Handle system attributes by using

7359 * expression.cs (Probe, Is, As): Split Probe in two classes Is and
7360 As that share bits of the implementation. Is returns a boolean,
7361 while As returns the Type that is being probed.
7363 2001-12-01 Ravi Pratap <ravi@ximian.com>
7365 * enum.cs (LookupEnumValue): Re-write various bits, return an object value
7366 instead of a Literal - much easier.
7368 (EnumInTransit): Remove - utterly useless :-)
7370 (Populate): Re-write bits - remove duplicate code etc. The code is much neater now.
7372 * expression.cs (MemberLookup): Cope with user-defined enums when they are in transit.
7374 * enum.cs (LookupEnumValue): Auto-compute next values by going down the dependency
7375 chain when we have no associated expression.

7496 * typemanager.cs (IsDelegateType, IsEnumType): Fix logic to determine
7499 * expression.cs (ArrayCreation::CheckIndices): Get rid of the require_constant

7504 (CheckIndices): Fix some tricky bugs thanks to recursion.
7506 * delegate.cs (NewDelegate::DoResolve): Re-write large portions as
7507 I was being completely brain-dead.
7509 (VerifyMethod, VerifyApplicability, VerifyDelegate): Make static
7510 and re-write acordingly.
7512 (DelegateInvocation): Re-write accordingly.
7514 * expression.cs (ArrayCreation::Emit): Handle string initialization separately.
7516 (MakeByteBlob): Handle types more correctly.
7518 * expression.cs (ArrayCreation:Emit): Write preliminary code to do
7519 initialization from expressions but it is incomplete because I am a complete
7522 2001-11-22 Miguel de Icaza <miguel@ximian.com>
7524 * statement.cs (If.Emit): Fix a bug that generated incorrect code
7525 on If. Basically, we have to return `true' (ie, we do return to
7526 our caller) only if both branches of the if return.
7528 * expression.cs (Binary.Emit): LogicalOr and LogicalAnd are
7529 short-circuit operators, handle them as short circuit operators.
7531 (Cast.DoResolve): Resolve type.
7532 (Cast.Cast): Take an expression as the target type.
7534 * cs-parser.jay (cast_expression): Remove old hack that only
7535 allowed a limited set of types to be handled. Now we take a
7536 unary_expression and we resolve to a type during semantic
7539 Use the grammar productions from Rhys to handle casts (this is
7540 not complete like Rhys syntax yet, we fail to handle that corner
7541 case that C# has regarding (-x), but we will get there.
7543 2001-11-22 Ravi Pratap <ravi@ximian.com>
7545 * class.cs (EmitFieldInitializer): Take care of the case when we have a
7546 field which is an array type.

7552 (everywhere): Use the above appropriately.
7554 * cs-parser.jay (for_statement): Update for array initialization while
7555 declaring variables.
7557 * ecore.cs : The error message was correct, it's the variable's names that
7558 were misleading ;-) Make the code more readable.
7560 (MemberAccess::DoResolve): Fix the code which handles Enum literals to set
7561 the correct type etc.
7563 (ConvertExplicit): Handle Enum types by examining the underlying type.
7565 2001-11-21 Ravi Pratap <ravi@ximian.com>

7578 BindingFlags.Instance as well
7580 * ecore.cs (Expression.TryImplicitIntConversion): Wrap the result
7581 implicit int literal conversion in an empty cast so that we
7582 propagate the right type upstream.
7584 (UnboxCast): new class used to unbox value types.
7585 (Expression.ConvertExplicit): Add explicit type conversions done
7588 (Expression.ImplicitNumericConversion): Oops, forgot to test for
7589 the target type before applying the implicit LongLiterals to ULong
7592 2001-11-21 Miguel de Icaza <miguel@ximian.com>
7594 * cs-parser.jay (for_statement): Reworked the way For works: now
7595 we declare manually any variables that are introduced in
7596 for_initializer to solve the problem of having out-of-band code
7597 emition (that is what got for broken).
7599 (declaration_statement): Perform the actual variable declaration
7600 that used to be done in local_variable_declaration here.
7602 (local_variable_declaration): Do not declare anything, just pass
7603 the information on a DictionaryEntry
7605 2001-11-20 Ravi Pratap <ravi@ximian.com>
7607 * expression.cs (ArrayCreation::CheckIndices): The story continues :-) Complete
7608 re-write of the logic to now make it recursive.

7631 DictionaryEntry since we need location info too.
7633 (constant_declaration): Update accordingly.
7635 * expression.cs (ArrayCreation): Make ValidateInitializers simpler by factoring
7636 code into another method : UpdateIndices.

7670 we can use this elsewhere.
7672 * statement.cs: Finish implementation of foreach for single
7675 * cs-parser.jay: Use an out-of-band stack to pass information
7676 around, I wonder why I need this.
7678 foreach_block: Make the new foreach_block the current_block.
7680 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
7681 function used to return a static Parameters structure. Used for
7682 empty parameters, as those are created very frequently.
7684 * cs-parser.jay, class.cs: Use GetEmptyReadOnlyParameters
7686 2001-11-15 Ravi Pratap <ravi@ximian.com>
7688 * interface.cs : Default modifier is private, not public. The
7689 make verify test passes again.
7691 2001-11-15 Ravi Pratap <ravi@ximian.com>
7693 * support.cs (ReflectionParameters): Fix logic to determine
7694 whether the last parameter is a params one. Test 9 passes again.
7696 * delegate.cs (Populate): Register the builders we define with
7697 RegisterParameterForBuilder. Test 19 passes again.
7699 * cs-parser.jay (property_declaration): Reference $6 instead
7700 of $$ to get at the location.
7702 (indexer_declaration): Similar stuff.
7706 * class.cs (Property): Register parameters for the Get and Set methods
7707 if they exist. Test 23 passes again.
7709 * expression.cs (ArrayCreation::Emit): Pass null for the method in the
7710 call to EmitArguments as we are sure there aren't any params arguments.
7711 Test 32 passes again.
7713 * suppor.cs (ParameterDesc, ParameterModifier): Fix trivial bug causing
7714 IndexOutOfRangeException.
7716 * class.cs (Property::Define): Register property using TypeManager.RegisterProperty
7717 Test 33 now passes again.
7719 2001-11-15 Miguel de Icaza <miguel@ximian.com>
7721 * cs-parser.jay: Kill horrendous hack ($??? = lexer.Location) that
7722 broke a bunch of things. Will have to come up with a better way
7723 of tracking locations.

7727 2001-11-09 Miguel de Icaza <miguel@ximian.com>

7748 way we can report the error correctly for missing return values.
7750 * class.cs (Method.Emit): Clean up.
7752 * expression.cs (Argument.Resolve): Take another argument: the
7753 location where this argument is used. Notice that this is not
7754 part of the "Argument" class as to reduce the size of the
7755 structure (we know the approximate location anyways).
7757 Test if the argument is a variable-reference, if not, then
7758 complain with a 206.
7760 (Argument.Emit): Emit addresses of variables.
7762 (Argument.FullDesc): Simplify.
7764 (Invocation.DoResolve): Update for Argument.Resolve.
7766 (ElementAccess.DoResolve): ditto.

7791 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
7792 enumerations that are used in heavily used structures derive from
7793 byte in a laughable and pathetic attempt to reduce memory usage.
7794 This is the kind of pre-optimzations that you should not do at
7795 home without adult supervision.
7797 * expression.cs (UnaryMutator): New class, used to handle ++ and
7798 -- separatedly from the other unary operators. Cleans up the
7799 code, and kills the ExpressionStatement dependency in Unary.
7801 (Unary): Removed `method' and `Arguments' from this class, making
7802 it smaller, and moving it all to SimpleCall, so I can reuse this
7803 code in other locations and avoid creating a lot of transient data
7804 strucutres when not required.
7806 * cs-parser.jay: Adjust for new changes.
7808 2001-11-11 Miguel de Icaza <miguel@ximian.com>
7810 * enum.cs (Enum.Populate): If there is a failure during

7871 * class.cs, rootcontext.cs : Update accordingly.
7873 * typemanager.cs (RegisterField, GetValue): Workarounds for the fact that

7878 * expression.cs (MemberAccess.DoResolve): Adjust code to obtain the value
7879 of a fieldinfo using the above, when dealing with a FieldBuilder.

7926 2001-11-09 Miguel de Icaza <miguel@ximian.com>
7928 * cs-parser.jay: A for_initializer if is a
7929 local_variable_declaration really ammount to have an implicit
7930 block with the variable declaration and no initializer for for.

7965 Emit method everywhere.
7967 * enum.cs (Enum): Revamp to use the same definition semantics as delegates so
7968 we have a DefineEnum, CloseEnum etc. The previous way of doing things was not right
7969 as we had no way of defining nested enums !
7971 * rootcontext.cs : Adjust code accordingly.
7973 * typemanager.cs (AddEnumType): To keep track of enum types separately.
7975 2001-11-07 Ravi Pratap <ravi@ximian.com>

8042 IStackStore as the order in which arguments are passed reflects
8045 * assign.cs: Instead of using expr.ExprClass to select the way of
8046 assinging, probe for the IStackStore/IAssignMethod interfaces.
8048 * typemanager.cs: Load InitializeArray definition.
8050 * rootcontext.cs (RootContext.MakeStaticData): Used to define
8051 static data that can be used to initialize arrays.

8183 Parameter.Modifier and not a string.
8185 (ReflectionParameters, InternalParameters): Update accordingly.
8187 * expression.cs (Argument::GetParameterModifier): Same here.
8189 * support.cs (InternalParameters::ParameterType): Find a better way of determining
8190 if we are a ref/out parameter. Actually, the type shouldn't be holding the '&'
8191 symbol in it at all so maybe this is only for now.
8193 2001-10-30 Ravi Pratap <ravi@ximian.com>
8195 * support.cs (InternalParameters): Constructor now takes an extra argument
8196 which is the actual Parameters class.

8646 methods on value types. We need to pass the address to structure
8647 methods rather than the object itself. (The equivalent code to
8648 emit "this" for structures leaves the entire structure on the
8649 stack instead of a pointer to it).
8651 (ParameterReference::DoResolve): Compute the real index for the
8652 argument based on whether the method takes or not a `this' pointer
8653 (ie, the method is static).

8694 to TypeContainer mapping to see if a type is user-defined.
8696 * class.cs (TypeContainer::CloseType): Implement.

8726 expected return type.
8728 Validate use of return statement.
8730 * codegen.cs (EmitContext): Pass the expected return type here.

8816 * class.cs: Catch static methods having the flags override,
8817 virtual or abstract.
8819 * expression.cs (UserCast): This user cast was not really doing
8820 what it was supposed to do. Which is to be born in fully resolved
8821 state. Parts of the resolution were being performed at Emit time!
8825 2001-10-05 Miguel de Icaza <miguel@ximian.com>
8827 * expression.cs: Implicity convert the result from UserCast.

8852 * expression.cs (Expression::ImplicitUserConversion): Rename to
8853 UserDefinedConversion.

8895 instead of inside a tight loop.
8897 (::RequireMethods): Accept an object as the data to set into the
8898 hashtable so we can report interface vs abstract method mismatch.
8900 2001-10-03 Miguel de Icaza <miguel@ximian.com>
8902 * report.cs: Make all of it static.
8904 * rootcontext.cs: Drop object_type and value_type computations, as
8905 we have those in the TypeManager anyways.

8935 an applicable member - according to the spec :-)
8936 Also fix logic to find members in base types.
8938 (Unary::ResolveOperator): Same here.
8940 (Unary::report23): Change name to error23 and make first argument a TypeContainer
8941 as I was getting thoroughly confused between this and error19 :-)
8943 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
8944 (::FindMostEncompassedType): Implement.
8945 (::FindMostEncompassingType): Implement.
8946 (::StandardConversionExists): Implement.
8948 (UserImplicitCast): Re-vamp. We now need info about most specific
8949 source and target types so that we can do the necessary conversions.
8951 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
8952 mathematical union with no duplicates.
8954 2001-10-03 Miguel de Icaza <miguel@ximian.com>
8956 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
8957 in order from base classes to child classes, so that we can in
8958 child classes look up in our parent for method names and
8959 attributes (required for handling abstract, virtual, new, override
8960 constructs: we need to instrospect our base class, and if we dont
8961 populate the classes in order, the introspection might be
8962 incorrect. For example, a method could query its parent before
8963 the parent has any methods and would determine that the parent has
8964 no abstract methods (while it could have had them)).
8966 (RootContext::CreateType): Record the order in which we define the
8969 2001-10-02 Miguel de Icaza <miguel@ximian.com>
8971 * class.cs (TypeContainer::Populate): Also method definitions can
8972 fail now, keep track of this.

8975 DeclaredOnly/noDeclaredOnly flag.
8977 (Constructor::Emit) Return the ConstructorBuilder.

8987 not marked abstract or extern).
8989 * expression.cs (TypeOf::Emit): Implement.
8991 * typemanager.cs: runtime_handle_type, new global type.
8993 * class.cs (Property::Emit): Generate code for properties.
8995 2001-10-02 Ravi Pratap <ravi@ximian.com>
8997 * expression.cs (Unary::ResolveOperator): Find operators on base type
8998 too - we now conform exactly to the spec.
9000 (Binary::ResolveOperator): Same here.
9002 * class.cs (Operator::Define): Fix minor quirk in the tests.
9004 * ../errors/cs0215.cs : Added.
9006 * ../errors/cs0556.cs : Added.
9008 * ../errors/cs0555.cs : Added.
9010 2001-10-01 Miguel de Icaza <miguel@ximian.com>
9012 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
9013 single integer which is really efficient
9015 2001-10-01 Ravi Pratap <ravi@ximian.com>
9017 * expression.cs (Expression::ImplicitUserConversion): Use location
9018 even in the case when we are examining True operators.
9020 * class.cs (Operator::Define): Perform extensive checks to conform
9021 with the rules for operator overloading in the spec.
9023 * expression.cs (Expression::ImplicitReferenceConversion): Implement
9024 some of the other conversions mentioned in the spec.
9026 * typemanager.cs (array_type): New static member for the System.Array built-in
9029 (cloneable_interface): For System.ICloneable interface.
9031 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
9032 we start resolving the tree and populating types.
9034 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
9036 2001-10-01 Miguel de Icaza <miguel@ximian.com>
9038 * expression.cs (Expression::ExprClassFromMemberInfo,
9039 Expression::Literalize): Create literal expressions from
9040 FieldInfos which are literals.
9042 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
9043 type casts, because they were wrong. The test suite in tests
9046 (ImplicitNumericConversion): ushort to ulong requires a widening
9049 Int32 constant to long requires widening cast as well.
9051 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
9052 for integers because the type on the stack is not i4.
9054 2001-09-30 Miguel de Icaza <miguel@ximian.com>
9056 * expression.cs (report118): require location argument.
9058 * parameter.cs: Do not dereference potential null value.
9060 * class.cs: Catch methods that lack the `new' keyword when
9061 overriding a name. Report warnings when `new' is used without
9062 anything being there to override.
9064 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
9066 * class.cs: Only add constructor to hashtable if it is non-null
9067 (as now constructors can fail on define).
9069 (TypeManager, Class, Struct): Take location arguments.
9071 Catch field instance initialization in structs as errors.
9073 accepting_filter: a new filter for FindMembers that is static so
9074 that we dont create an instance per invocation.
9076 (Constructor::Define): Catch errors where a struct constructor is
9079 * cs-parser.jay: Pass location information for various new
9082 * delegate.cs (Delegate): take a location argument.
9084 * driver.cs: Do not call EmitCode if there were problesm in the
9085 Definition of the types, as many Builders wont be there.
9087 * decl.cs (Decl::Decl): Require a location argument.
9089 * cs-tokenizer.cs: Handle properly hex constants that can not fit
9090 into integers, and find the most appropiate integer for it.
9092 * literal.cs: Implement ULongLiteral.
9094 * rootcontext.cs: Provide better information about the location of
9095 failure when CreateType fails.
9097 2001-09-29 Miguel de Icaza <miguel@ximian.com>
9099 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
9102 * expression.cs (Binary::CheckShiftArguments): Add missing type
9104 (Binary::ResolveOperator): Add type to the logical and and logical
9105 or, Bitwise And/Or and Exclusive Or code paths, it was missing
9108 (Binary::DoNumericPromotions): In the case where either argument
9109 is ulong (and most signed types combined with ulong cause an
9110 error) perform implicit integer constant conversions as well.
9112 2001-09-28 Miguel de Icaza <miguel@ximian.com>
9114 * expression.cs (UserImplicitCast): Method should always be
9116 (Invocation::BetterConversion): Simplified test for IntLiteral.
9118 (Expression::ImplicitNumericConversion): Split this routine out.
9119 Put the code that performs implicit constant integer conversions
9122 (Expression::Resolve): Become a wrapper around DoResolve so we can
9123 check eclass and type being set after resolve.
9125 (Invocation::Badness): Remove this dead function
9127 (Binary::ResolveOperator): Do not compute the expensive argumnets
9128 unless we have a union for it.
9130 (Probe::Emit): Is needs to do an isinst and then
9131 compare against null.
9133 (::CanConvert): Added Location argument. If the Location argument
9134 is null (Location.Null), then we do not report errors. This is
9135 used by the `probe' mechanism of the Explicit conversion. We do
9136 not want to generate an error for something that the user
9137 explicitly requested to be casted. But the pipeline for an
9138 explicit cast first tests for potential implicit casts.
9140 So for now, if the Location is null, it means `Probe only' to
9141 avoid adding another argument. Might have to revise this
9144 (ClassCast): New class used to type cast objects into arbitrary
9145 classes (used in Explicit Reference Conversions).
9147 Implement `as' as well.
9149 Reverted all the patches from Ravi below: they were broken:
9151 * The use of `level' as a mechanism to stop recursive
9152 invocations is wrong. That was there just to catch the
9153 bug with a strack trace but not as a way of addressing
9156 To fix the problem we have to *understand* what is going
9157 on and the interactions and come up with a plan, not
9158 just get things going.
9160 * The use of the type conversion cache that I proposed
9161 last night had an open topic: How does this work across
9162 protection domains. A user defined conversion might not
9163 be public in the location where we are applying the
9164 conversion, a different conversion might be selected
9165 (ie, private A->B (better) but public B->A (worse),
9166 inside A, A->B applies, but outside it, B->A will
9169 * On top of that (ie, even if the above is solved),
9170 conversions in a cache need to be abstract. Ie, `To
9171 convert from an Int to a Short use an OpcodeCast', not
9172 `To convert from an Int to a Short use the OpcodeCast on
9173 the variable 5' (which is what this patch was doing).
9175 2001-09-28 Ravi Pratap <ravi@ximian.com>
9177 * expression.cs (Invocation::ConversionExists): Re-write to use
9178 the conversion cache
9180 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
9181 cache all conversions done, not just user-defined ones.
9183 (Invocation::BetterConversion): The real culprit. Use ConversionExists
9184 to determine if a conversion exists instead of acutually trying to
9185 perform the conversion. It's faster too.
9187 (Expression::ConvertExplicit): Modify to use ConversionExists to check
9188 and only then attempt the implicit conversion.
9190 2001-09-28 Ravi Pratap <ravi@ximian.com>
9192 * expression.cs (ConvertImplicit): Use a cache for conversions
9193 already found. Check level of recursion and bail out if necessary.
9195 2001-09-28 Miguel de Icaza <miguel@ximian.com>
9197 * typemanager.cs (string_concat_string_string, string_concat_object_object):
9198 Export standard methods that we expect for string operations.
9200 * statement.cs (Block::UsageWarning): Track usage of variables and
9201 report the errors for not used variables.
9203 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
9206 2001-09-27 Miguel de Icaza <miguel@ximian.com>
9208 * codegen.cs: remove unnneded code
9210 * expression.cs: Removed BuiltinTypeAccess class
9212 Fix the order in which implicit conversions are
9215 The previous fixed dropped support for boxed conversions (adding a
9216 test to the test suite now)
9218 (UserImplicitCast::CanConvert): Remove test for source being null,
9219 that code is broken. We should not feed a null to begin with, if
9220 we do, then we should track the bug where the problem originates
9221 and not try to cover it up here.
9223 Return a resolved expression of type UserImplicitCast on success
9224 rather than true/false. Ravi: this is what I was talking about,
9225 the pattern is to use a static method as a "constructor" for
9228 Also, do not create arguments until the very last minute,
9229 otherwise we always create the arguments even for lookups that
9230 will never be performed.
9232 (UserImplicitCast::Resolve): Eliminate, objects of type
9233 UserImplicitCast are born in a fully resolved state.
9235 * typemanager.cs (InitCoreTypes): Init also value_type
9238 * expression.cs (Cast::Resolve): First resolve the child expression.
9240 (LValue): Add new method AddressOf to be used by
9243 Change the argument of Store to take an EmitContext instead of an
9244 ILGenerator, because things like FieldExpr need to be able to call
9245 their children expression to generate the instance code.
9247 (Expression::Error, Expression::Warning): Sugar functions for
9250 (Expression::MemberLookup): Accept a TypeContainer instead of a
9251 Report as the first argument.
9253 (Expression::ResolvePrimary): Killed. I still want to improve
9254 this as currently the code is just not right.
9256 (Expression::ResolveMemberAccess): Simplify, but it is still
9259 (Unary::Resolve): Catch errors in AddressOf operators.
9261 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
9262 index to a byte for the short-version, or the compiler will choose
9263 the wrong Emit call, which generates the wrong data.
9265 (ParameterReference::Emit, ::Store): same.
9267 (FieldExpr::AddressOf): Implement.
9269 * typemanager.cs: TypeManager: made public variable instead of
9272 * driver.cs: document --fatal.
9274 * report.cs (ErrorMessage, WarningMessage): new names for the old
9275 Error and Warning classes.
9277 * cs-parser.jay (member_access): Turn built-in access to types
9278 into a normal simplename
9280 2001-09-27 Ravi Pratap <ravi@ximian.com>

9283 with q being null, since this was introducing a bug.
9285 * expression.cs (ConvertImplicit): Do built-in conversions first.
9287 2001-09-27 Ravi Pratap <ravi@ximian.com>
9289 * expression.cs (UserImplicitCast::Resolve): Fix bug.
9291 2001-09-27 Ravi Pratap <ravi@ximian.com>
9293 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
9294 I had introduced long ago (what's new ?).
9296 * expression.cs (UserImplicitCast::CanConvert): Static method to do
9297 the work of all the checking.
9298 (ConvertImplicit): Call CanConvert and only then create object if necessary.
9299 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
9301 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
9302 that is the right way.
9304 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
9305 overloading resolution. Use everywhere instead of cutting and pasting code.
9307 (Binary::ResolveOperator): Use MakeUnionSet.
9309 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
9310 we have to convert to bool types. Not complete yet.

9314 * typemanager.cs (TypeManager::CSharpName): support ushort.
9316 * expression.cs (Expression::TryImplicitIntConversion): Attempts
9317 to provide an expression that performsn an implicit constant int
9318 conversion (section 6.1.6).
9319 (Expression::ConvertImplicitRequired): Reworked to include
9320 implicit constant expression conversions.
9322 (Expression::ConvertNumericExplicit): Finished.
9324 (Invocation::Emit): If InstanceExpression is null, then it means
9325 that we perform a call on this.
9327 2001-09-26 Miguel de Icaza <miguel@ximian.com>
9329 * expression.cs (Unary::Emit): Remove some dead code.
9330 (Probe): Implement Resolve and Emit for `is'.
9331 (Expression::ConvertImplicitRequired): Attempt to do constant
9332 expression conversions here. Maybe should be moved to
9333 ConvertImplicit, but I am not sure.
9334 (Expression::ImplicitLongConstantConversionPossible,
9335 Expression::ImplicitIntConstantConversionPossible): New functions
9336 that tell whether is it possible to apply an implicit constant
9337 expression conversion.

9342 * cs-parser.jay: Update operator constants.
9344 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
9345 (Parameters::GetSignature): Hook up VerifyArgs here.
9346 (Parameters::VerifyArgs): Verifies that no two arguments have the
9349 * class.cs (Operator): Update the operator names to reflect the
9350 ones that the spec expects (as we are just stringizing the
9353 * expression.cs (Unary::ResolveOperator): Fix bug: Use
9354 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
9355 previous usage did only work for our methods.
9356 (Expression::ConvertImplicit): Handle decimal implicit numeric
9357 conversions as well.
9358 (Expression::InternalTypeConstructor): Used to invoke constructors
9359 on internal types for default promotions.
9361 (Unary::Emit): Implement special handling for the pre/post
9362 increment/decrement for overloaded operators, as they need to have
9363 the same semantics as the other operators.
9365 (Binary::ResolveOperator): ditto.
9366 (Invocation::ConversionExists): ditto.
9367 (UserImplicitCast::Resolve): ditto.
9369 2001-09-26 Ravi Pratap <ravi@ximian.com>
9371 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded
9372 operator, return after emitting body. Regression tests pass again !

9375 (Unary::ForceConversion, Binary::ForceConversion): Ditto.
9376 (Invocation::OverloadResolve): Ditto.
9377 (Invocation::BetterFunction, BetterConversion, ConversionExists): Ditto.
9379 * everywhere : update calls to the above methods accordingly.
9381 2001-09-26 Miguel de Icaza <miguel@ximian.com>
9383 * assign.cs (Assign): Make it inherit from ExpressionStatement.
9385 * expression.cs (ExpressionStatement): New base class used for
9386 expressions that can appear in statements, so that we can provide
9387 an alternate path to generate expression that do not leave a value
9390 (Expression::Emit, and all the derivatives): We no longer return
9391 whether a value is left on the stack or not. Every expression
9392 after being emitted leaves a single value on the stack.
9394 * codegen.cs (EmitContext::EmitStatementExpression): Use the
9395 facilties of ExpressionStatement if possible.
9397 * cs-parser.jay: Update statement_expression.

9405 * expression.cs (Binary::ResolveOperator): Had forgottten to set
9406 the type of the expression to the return type of the method if
9407 we have an overloaded operator match ! The regression tests pass again !
9408 (Unary::ResolveOperator): Ditto.
9410 * expression.cs (Invocation::ConversionExists): Correct the member lookup
9411 to find "op_Implicit", not "implicit" ;-)
9412 (UserImplicitCast): New class to take care of user-defined implicit conversions.

9415 * everywhere : Correct calls to the above accordingly.
9417 * expression.cs (UserImplicitCast::Resolve, ::Emit): Implement.
9418 (ConvertImplicit): Do user-defined conversion if it exists.
9420 2001-09-24 Miguel de Icaza <miguel@ximian.com>
9422 * assign.cs: track location.
9423 (Resolve): Use implicit conversions on assignment.
9425 * literal.cs: Oops. Not good, Emit of short access values should

9428 * expression.cs (Unary::Emit): Emit code for -expr.
9430 (Unary::ResolveOperator): Handle `Substract' for non-constants
9431 (substract from zero from the non-constants).

9466 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
9467 Also take an additional TypeContainer argument.

9471 * typemanager.cs (CSharpName): Update to check for the string type and return
9474 * expression.cs (Invocation::FullMethodDesc): New static method to return a string fully describing
9477 2001-09-21 Ravi Pratap <ravi@ximian.com>
9479 * expression.cs (Invocation::OverloadResolve): Re-write to conform more to the spec.
9480 (Invocation::BetterFunction): Implement.
9481 (Invocation::BetterConversion): Implement.
9482 (Invocation::ConversionExists): Skeleton, no implementation yet.
9484 Okay, things work fine !
9486 2001-09-21 Miguel de Icaza <miguel@ximian.com>
9488 * typemanager.cs: declare and load enum_type, delegate_type and
9491 * expression.cs (Expression::Emit): Now emit returns a value that
9492 tells whether a value is left on the stack or not. This strategy
9493 might be reveted tomorrow with a mechanism that would address
9494 multiple assignments.
9495 (Expression::report118): Utility routine to report mismatches on
9498 (Unary::Report23): Report impossible type/operator combination
9501 (Unary::IsIncrementableNumber): Whether the type can be

9535 * expression.cs (SimpleName::ResolveSimpleName): Error if we can
9538 * cs-parser.jay (QualifierIdentifier): Pass location to SimpleName
9541 * statement.cs (Block::EmitMeta): Reuse the count across all the variables,
9542 otherwise nested blocks end up with the same index.
9544 * codegen.cs (CodeGen::EmitTopBlock): Pass initial sequence
9546 * expression.cs: Instead of having FIXMEs in the Resolve
9547 functions, throw exceptions so it is obvious that we are facing a
9550 * cs-parser.jay (invocation_expression): Pass Location information.
9552 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
9553 Use a basename for those routines because .NET does not like paths

9559 2001-09-19 Miguel de Icaza <miguel@ximian.com>
9561 * typemanager.cs (TypeManager::CoreLookupType): A function to make sure that we

9565 * expression.cs (Unary::ResolveOperator): return the child
9566 expression for expressions which are just +expr.

9570 expression conversions'.
9572 * literal.cs (LongLiteral): Implement long literal class.
9573 (IntLiteral): export the `Value' of the intliteral.
9575 2001-09-19 Ravi Pratap <ravi@ximian.com>
9577 * expression.cs (Binary::Emit): Finally get the emission right ! Woo!
9579 * class.cs (Operator::Define): Change the methodname prefix to 'op_'
9580 instead of 'Operator'
9582 * expression.cs (Binary::ResolveOperator): Update accordingly.
9583 (Unary::Operator): Change names to 'Add' and 'Subtract' instead 'Plus'

9590 * expression.cs (Unary::Resolve): Implement.
9591 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
9592 operators are found instead of making noise ;-)

9594 Binary::ResolveOperator does for Binary expressions.
9595 (Unary.method, .Arguments): Add.
9596 (Unary::OperName): Implement.
9597 (Unary::ForceConversion): Copy and Paste !
9599 * class.cs (Operator::Define): Fix a small bug for the case when we have
9602 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
9603 for the inbuilt operators. Only overloading works for now ;-)
9605 2001-09-18 Miguel de Icaza <miguel@ximian.com>

9621 (FieldExpr::Emit): Implement.
9623 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
9624 the last instruction contains a return opcode to avoid generating
9625 the last `ret' instruction (this generates correct code, and it is
9626 nice to pass the peverify output).
9628 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
9629 initializer for static and instance variables.
9630 (Constructor::Emit): Allow initializer to be null in the case of
9631 static constructors. Only emit initializer for instance
9634 (TypeContainer::FindMembers): Return a null array if there are no
9637 Also fix the code for the MemberTypes.Method branch, as it was not
9638 scanning that for operators (or tried to access null variables before).
9640 * assign.cs (Assign::Emit): Handle instance and static fields.
9644 * driver.cs: Stop compilation if there are parse errors.
9646 * cs-parser.jay (constructor_declaration): Provide default base
9647 initializer for non-static constructors.
9648 (constructor_declarator): Do not provide a default base
9649 initializers if none was specified.
9650 Catch the fact that constructors should not have parameters.
9652 * class.cs: Do not emit parent class initializers for static
9653 constructors, that should be flagged as an error.
9655 2001-09-18 Ravi Pratap <ravi@ximian.com>
9657 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.

9687 (Expression::MemberLookup): Provide a version that allows to
9688 specify the MemberTypes and BindingFlags.
9690 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
9691 so it was not fetching variable information from outer blocks.
9693 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
9694 Beforefieldinit as it was buggy.
9696 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
9699 * class.cs (Constructor::Emit): Only emit if block is not null.
9700 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
9701 deal with this by semantically definining it as if the user had

9793 * modifiers.cs: Do not use `parent', instead use the real type
9794 container to evaluate permission settings.
9796 * class.cs: Put Ravi's patch back in. He is right, and we will
9797 have to cope with the
9799 2001-09-14 Ravi Pratap <ravi@ximian.com>
9801 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

9806 * driver.cs: Added --parse option that only parses its input files
9809 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
9810 incorrect. IsTopLevel is not used to tell whether an object is
9811 root_types or not (that can be achieved by testing this ==
9812 root_types). But to see if this is a top-level *class* (not
9813 necessarly our "toplevel" container).
9815 2001-09-14 Ravi Pratap <ravi@ximian.com>
9817 * enum.cs (Enum::Define): Modify to call the Lookup method on the

9823 Modifiers.TypeAttr. This should just be a call to that method.
9825 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
9826 object so that we can determine if we are top-level or not.
9828 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
9831 * enum.cs (Enum::Define): Ditto.
9833 * modifiers.cs (FieldAttr): Re-write.

9839 * modifiers.cs (MethodAttr): Re-write.
9840 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
9842 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent

9845 2001-09-13 Miguel de Icaza <miguel@ximian.com>
9847 * expression.cs (MemberLookup): Fruitless attempt to lookup
9848 constructors. Maybe I need to emit default constructors? That
9849 might be it (currently .NET emits this for me automatically).
9850 (Invocation::OverloadResolve): Cope with Arguments == null.
9851 (Invocation::EmitArguments): new function, shared by the new
9853 (Invocation::Emit): Handle static and instance methods. Emit

9873 objects that we might have around.
9875 (Populate): Only initialize method_builders_to_methods once.
9877 * expression.cs (PropertyExpr): Initialize type from the
9880 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

9885 (Binary::ResolveOperator): Set the return type to boolean for
9886 comparission operators
9888 * typemanager.cs: Remove debugging print code.
9890 (Invocation::Resolve): resolve type.
9892 * class.cs: Allocate a MemberInfo of the correct size, as the code
9893 elsewhere depends on the test to reflect the correct contents.
9895 (Method::) Keep track of parameters, due to System.Reflection holes
9897 (TypeContainer::Populate): Keep track of MethodBuilders to Method
9900 (TypeContainer::FindMembers): Use ArrayList and then copy an array
9901 of the exact size and return that.
9903 (Class::LookupMethodByBuilder): New function that maps
9904 MethodBuilders to its methods. Required to locate the information
9905 on methods because System.Reflection bit us again.
9907 * support.cs: New file, contains an interface ParameterData and
9908 two implementations: ReflectionParameters and InternalParameters
9909 used to access Parameter information. We will need to grow this
9912 * expression.cs (Invocation::GetParameterData): implement a cache
9913 and a wrapper around the ParameterData creation for methods.
9914 (Invocation::OverloadResolve): Use new code.

9970 2001-09-12 Ravi Pratap <ravi@ximian.com>
9972 * class.cs (TypeContainer::FindMembers): Method which does exactly
9973 what Type.FindMembers does, only we don't have to use reflection. No

9977 typecontainer objects as we need to get at them.
9978 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

10020 addOn_ and removeOn_

10343 (Event.EventBuilder): New member.
10345 * class.cs (TypeContainer::Populate): Update to define all enums and events

10352 * class.cs (Property): Revamp to use the convention of making fields readonly.

10402 general catch clauses by being a little smart ;-)
10404 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
10405 Hooray, try and catch statements parse fine !

10428 (indexer_declarator): Implement actions.
10429 (parsing_indexer): New local boolean used to keep track of whether
10430 we are parsing indexers or properties. This is necessary because
10431 implicit_parameters come into picture even for the get accessor in the
10432 case of an indexer.
10433 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
10435 * class.cs (Indexer): New class for indexer declarations.

10457 concatenating all the commas together, just as they appear.
10458 (opt_dim_separators): Modify accordingly

10460 thing - instead, collect the brackets here.
10461 (opt_rank_sepcifiers): Modify accordingly.

10463 instead of ignoring the rank_specifiers.
10464 (expression_list): Implement to collect the expressions

10468 (array_initializer): Make it a list of variable_initializers
10469 (opt_array_initializer): Modify accordingly.

10490 * typemanager.cs (InitCoreTypes): Initialize the various core
10491 types after we have populated the type manager with the user
10492 defined types (this distinction will be important later while
10493 compiling corlib.dll)
10495 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
10496 on Expression Classification. Now all expressions have a method
10497 `Resolve' and a method `Emit'.
10499 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
10500 generation from working. Also add some temporary debugging
10503 2001-08-24 Miguel de Icaza <miguel@ximian.com>
10505 * codegen.cs: Lots of code generation pieces. This is only the
10506 beginning, will continue tomorrow with more touches of polish. We
10507 handle the fundamentals of if, while, do, for, return. Others are
10508 trickier and I need to start working on invocations soon.
10510 * gen-treedump.cs: Bug fix, use s.Increment here instead of
10513 * codegen.cs (EmitContext): New struct, used during code
10514 emission to keep a context. Most of the code generation will be
10517 * cs-parser.jay: Add embedded blocks to the list of statements of
10518 this block. So code generation proceeds in a top down fashion.

10543 and made a method, optional argument tells whether this is a class
10544 or a structure to apply the `has-this' bit.

10573 instead of properties.
10575 (Constructor::IsDefault): Whether this is a default constructor.
10577 (Field::) use readonly public fields instead of properties also.
10579 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
10580 track of static constructors; If none is used, turn on
10581 BeforeFieldInit in the TypeAttributes.
10583 * cs-parser.jay (opt_argument_list): now the return can be null
10584 for the cases where there are no arguments.
10586 (constructor_declarator): If there is no implicit `base' or

10589 * modifiers.cs (MethodAttr): New static function maps a set of
10590 modifiers flags into a MethodAttributes enum
10591 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
10592 MethodAttr, TypeAttr to represent the various mappings where the
10593 modifiers are used.
10594 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'

10619 instead of doing this always.
10621 * parameter.cs: Handle refs and out parameters.
10623 * cs-parser.jay: Use an ArrayList to construct the arguments
10624 instead of the ParameterCollection, and then cast that to a

10650 this System.Reflection code is. Kudos to Microsoft
10652 * typemanager.cs: Implement a type cache and avoid loading all
10653 types at boot time. Wrap in LookupType the internals. This made
10654 the compiler so much faster. Wow. I rule!
10656 * driver.cs: Make sure we always load mscorlib first (for
10657 debugging purposes, nothing really important).
10659 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
10660 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
10662 * rootcontext.cs: Lookup types on their namespace; Lookup types
10663 on namespaces that have been imported using the `using' keyword.

10727 RecordInterface instead.
10729 * cs-parser.jay: Updated to reflect changes above.
10731 * decl.cs (Definition): Keep track of the TypeBuilder type that

10821 (ResolveType): New function to launch the resolution process, only
10822 used by interfaces for now.
10824 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
10825 that are inserted into the name space.
10827 2001-06-08 Miguel de Icaza <miguel@ximian.com>
10829 * ARGH. I have screwed up my tree so many times due to the use of
10830 rsync rather than using CVS. Going to fix this at once.
10832 * driver.cs: Objetify driver. Load assemblies, use assemblies to
10835 2001-06-07 Miguel de Icaza <miguel@ximian.com>
10837 * Experiment successful: Use System.Type rather that our own
10840 2001-05-25 Miguel de Icaza <miguel@ximian.com>
10842 * cs-parser.jay: Removed nsAliases from here.
10844 Use new namespaces, handle `using XXX;'
10846 * namespace.cs: Reimplemented namespace handling, use a recursive
10847 definition of the class. Now we can keep track of using clauses
10848 and catch invalid using clauses.
10850 2001-05-24 Miguel de Icaza <miguel@ximian.com>
10852 * gen-treedump.cs: Adapted for all the renaming.
10854 * expression.cs (Expression): this class now has a Type property
10855 which returns an expression Type.
10857 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
10858 `Type', as this has a different meaning now in the base
10860 2001-05-22 Miguel de Icaza <miguel@ximian.com>
10862 * interface.cs, class.cs: Removed from all the sources the
10863 references to signature computation, as we can not do method
10864 signature computation during the parsing time, as we are not
10865 trying to solve at that point distinguishing:
10869 void a (NS.Blah x) {}
10872 Which depending on the context might be valid or not, as we do not
10873 know if Blah is the same thing as NS.Blah at that point.
10875 * Redid everything so the code uses TypeRefs now instead of
10876 Types. TypeRefs are just temporary type placeholders, that need
10877 to be resolved. They initially have a pointer to a string and the
10878 current scope in which they are used. This is used later by the
10879 compiler to resolve the reference to an actual Type.
10881 * DeclSpace is no longer a CIR.Type, and neither are
10882 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
10883 are all DeclSpaces, but no Types.
10885 * type.cs (TypeRefManager): This implements the TypeRef manager,
10886 which keeps track of all the types that need to be resolved after
10887 the parsing has finished.
10889 2001-05-13 Miguel de Icaza <miguel@ximian.com>
10891 * ARGH. We are going to have to store `foreach' as a class rather
10892 than resolving it, as we need to verify error 1579 after name
10893 resolution. *OR* we could keep a flag that says `This request to
10894 IEnumerator comes from a foreach statement' which we can then use
10895 to generate the error.
10897 2001-05-10 Miguel de Icaza <miguel@ximian.com>
10899 * class.cs (TypeContainer.AddMethod): we now add methods to the
10900 MethodGroup instead of the method hashtable.
10902 * expression.cs: Add MethodGroup abstraction, which gets us one
10903 step closer to the specification in the way we handle method
10906 * cs-parser.jay (primary_expression): qualified_identifier now
10907 tried to match up an identifier to a local variable reference or
10908 to a parameter reference.
10910 current_local_parameters is now a parser global variable that
10911 points to the current parameters for the block, used during name
10914 (property_declaration): Now creates an implicit `value' argument to
10917 2001-05-09 Miguel de Icaza <miguel@ximian.com>
10919 * parameter.cs: Do not use `param' arguments as part of the
10920 signature, per the spec.
10922 2001-05-08 Miguel de Icaza <miguel@ximian.com>
10924 * decl.cs: Base class for classes, structs and interfaces. This
10925 is the "Declaration Space"
10927 * cs-parser.jay: Use CheckDef for checking declaration errors
10928 instead of having one on each function.
10930 * class.cs: Factor out some code for handling error handling in
10931 accordance to the "Declarations" section in the "Basic Concepts"
10932 chapter in the ECMA C# spec.
10934 * interface.cs: Make all interface member classes derive from
10935 InterfaceMemberBase.
10937 2001-05-07 Miguel de Icaza <miguel@ximian.com>
10939 * Many things: all interfaces are parsed and generated in
10940 gen-treedump. Support for member variables, constructors,
10941 destructors, properties, constants is there.
10943 Beginning of the IL backend, but very little done, just there for
10946 2001-04-29 Miguel de Icaza <miguel@ximian.com>
10948 * cs-parser.jay: Fix labeled statement.
10950 * cs-tokenizer.cs (escape): Escape " and ' always.
10951 ref_line, ref_name: keep track of the line/filename as instructed
10952 by #line by the compiler.
10955 2001-04-27 Miguel de Icaza <miguel@ximian.com>
10957 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
10958 to match the values in System.CodeDOM.
10960 Divid renamed to Divide.
10962 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
10964 (Statements.set): remove.
10966 * System.CodeDOM/CodeCatchClause.cs: always have a valid
10969 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
10970 falseStatements always have valid values.
10972 * cs-parser.jay: Use System.CodeDOM now.
