1 2002-06-21 Miguel de Icaza <miguel@ximian.com>
3 * class.cs (Property.Define): Only define the property if we are
4 not explicitly implementing a property from an interface. Use the
5 correct name also for those properties (the same CSC uses,
6 although that is really not needed).
8 (Property.Emit): Do not emit attributes for explicitly implemented
9 properties, as there is no TypeBuilder.
11 (Indexer.Emit): ditto.
13 Hiding then means that we do not really *implement* a pending
14 implementation, which makes code fail.
16 2002-06-22 Martin Baulig <martin@gnome.org>
18 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
19 the return value of Object.GetType(). [FIXME: we need to do this whenever
20 we get a type back from the reflection library].
22 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
24 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
26 2002-06-20 Miguel de Icaza <miguel@ximian.com>
28 * attribute.cs: Return null if we can not look up the type.
30 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
31 the interface types found.
33 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
34 interface types found.
36 * typemanager.cs (GetInterfaces): Make this routine returns alll
37 the interfaces and work around the lame differences between
38 System.Type and System.Reflection.Emit.TypeBuilder in the results
39 result for GetInterfaces.
41 (ExpandInterfaces): Given an array of interface types, expand and
42 eliminate repeated ocurrences of an interface. This expands in
43 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
46 2002-06-21 Martin Baulig <martin@gnome.org>
48 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
51 2002-06-21 Martin Baulig <martin@gnome.org>
53 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
54 and called with one of the core types, return the corresponding typebuilder for
57 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
60 2002-06-21 Martin Baulig <martin@gnome.org>
62 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
63 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
64 (Expression.ConvertReferenceExplicit): Likewise.
66 * expression.cs (ElementAccess.DoResolve): Likewise.
67 (ElementAccess.DoResolveLValue): Likewise.
69 2002-06-10 Martin Baulig <martin@gnome.org>
71 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
72 add the "value" parameter to the parameter list.
74 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
77 2002-06-19 Miguel de Icaza <miguel@ximian.com>
79 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
80 the argument to an int, uint, long or ulong, per the spec. Also
81 catch negative constants in array creation.
83 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
85 * class.cs: do not allow the same interface to appear twice in
88 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
90 * ecore.cs: don't use ldlen with System.Array.
92 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
94 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
96 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
98 * modifiers.cs: produce correct field attributes for protected
99 internal. Easy fix so miguel can work on ther harder stuff:-)
101 2002-06-18 Miguel de Icaza <miguel@ximian.com>
103 * pending.cs: New file. Move the code from class.cs here.
104 Support clearning the pending flag for all methods (when not doing
105 explicit interface implementation).
107 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
109 * rootcontext.cs: added a couple more types needed to bootstrap.
111 2002-06-17 Miguel de Icaza <miguel@ximian.com>
113 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
114 constructor in the type, instead of any constructor in the type
115 hierarchy. Thanks to Paolo for finding this bug (it showed up as
116 a bug in the Mono runtime when applying the params attribute).
118 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
119 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
121 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
123 * expression.cs (Unary.ResolveOperator): Use TypeManager
126 2002-06-13 Ravi Pratap <ravi@ximian.com>
128 * cs-parser.jay (enum_member_declaration): Pass in the attributes
131 * enum.cs (AddEnumMember): Add support to store the attributes associated
132 with each member too.
134 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
135 field builders too - this takes care of the enum member case.
137 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
139 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
140 address-of operator on both value types and pointers.
142 2002-06-10 Martin Baulig <martin@gnome.org>
144 * interface.cs (Interface.PopulateIndexer): Add the indexer's
145 PropertyBuilder to the `property_builders' list.
147 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
148 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
149 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
150 find any indexers which are inherited from an interface.
152 2002-06-09 Martin Baulig <martin@gnome.org>
154 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
155 the same type as the constant if necessary. There's also a test-130.cs
158 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
160 * typemanager.cs (TypeManager.ChangeType): Previously known as
161 Enum.ChangeEnumType().
163 2002-06-09 Martin Baulig <martin@gnome.org>
165 * expression.cs (Cast.TryReduce): Added support for consts.
167 2002-06-08 Ravi Pratap <ravi@ximian.com>
169 * class.cs (Accessor): Hold attributes information so we can pass
172 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
173 Modify to pass in attributes attached to the methods.
175 (add_accessor_declaration, remove_accessor_declaration): Ditto.
177 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
178 to handle the Accessor kind :-)
180 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
182 2002-06-08 Martin Baulig <martin@gnome.org>
184 * expression.cs (Unary.TryReduceNegative): Added support for
187 2002-06-08 Martin Baulig <martin@gnome.org>
189 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
190 name can't be found in the `defined_names' - the caller will do a
191 MemberLookup in this case and thus find methods in System.Enum
192 such as Enum.IsDefined().
194 2002-06-08 Martin Baulig <martin@gnome.org>
196 * enum.cs (Enum.ChangeEnumType): This is a custom version of
197 Convert.ChangeType() which works with TypeBuilder created types.
198 (Enum.LookupEnumValue, Enum.Define): Use it here.
200 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
201 `TypeBuilder.BaseType != null' check.
202 (TypeContainer.FindMembers): Only lookup parent members if we
203 actually have a parent.
204 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
205 (ConstructorInitializer.Resolve): Likewise.
207 * interface.cs (Interface.FindMembers): Added
208 `TypeBuilder.BaseType != null' check.
210 * rootcontext.cs (RootContext.ResolveCore): Added
211 "System.Runtime.CompilerServices.IndexerNameAttribute" to
212 classes_second_stage.
214 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
215 debug_type and trace_type when compiling with --nostdlib.
217 2002-06-07 Martin Baulig <martin@gnome.org>
219 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
220 (AddField): Set it to true when adding a non-static field.
221 (DefineType): Use `have_nonstatic_fields' to find out whether we
222 have non-static fields, not `Fields != null'.
224 2002-06-02 Miguel de Icaza <miguel@ximian.com>
226 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
227 dereferencing a null on the static-field code path)
229 2002-05-30 Martin Baulig <martin@gnome.org>
231 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
232 to take command line arguments. Use reflection to call the new
233 custom `Initialize' function on the symbol writer and pass it the
234 command line arguments.
236 * driver.cs (--debug-args): New command line argument to pass command
237 line arguments to the symbol writer.
239 2002-05-28 Miguel de Icaza <miguel@ximian.com>
241 * assign.cs (DoResolve): Forgot to do the implicit conversion to
242 the target type for indexers and properties. Thanks to Joe for
245 2002-05-27 Miguel de Icaza <miguel@ximian.com>
247 * typemanager.cs (MethodFlags): returns the method flags
248 (Obsolete/ShouldIgnore) that control warning emission and whether
249 the invocation should be made, or ignored.
251 * expression.cs (Invocation.Emit): Remove previous hack, we should
252 not do this on matching a base type, we should do this based on an attribute
254 Only emit calls to System.Diagnostics.Debug and
255 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
258 * rootcontext.cs: Global settings for tracing and debugging.
260 * cs-tokenizer.cs (define): New utility function to track
261 defines. Set the global settings for TRACE and DEBUG if found.
263 2002-05-25 Ravi Pratap <ravi@ximian.com>
265 * interface.cs (Populate*): Pass in the TypeContainer as well as
266 the DeclSpace as parameters so that we can create EmitContexts and
267 then use that to apply attributes etc.
269 (PopulateMethod, PopulateEvent, PopulateProperty)
270 (PopulateIndexer): Apply attributes everywhere.
272 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
275 (ApplyAttributes): Update accordingly.
277 We now apply interface attributes for all members too.
279 2002-05-26 Miguel de Icaza <miguel@ximian.com>
281 * class.cs (Indexer.Define); Correctly check if we are explicit
282 implementation (instead of checking the Name for a ".", we
283 directly look up if the InterfaceType was specified).
285 Delay the creation of the PropertyBuilder.
287 Only create the PropertyBuilder if we are not an explicit
288 interface implementation. This means that explicit interface
289 implementation members do not participate in regular function
290 lookups, and hence fixes another major ambiguity problem in
291 overload resolution (that was the visible effect).
293 (DefineMethod): Return whether we are doing an interface
296 * typemanager.cs: Temporary hack until we get attributes in
297 interfaces (Ravi is working on that) and we get IndexerName
298 support in interfaces.
300 * interface.cs: Register the indexers as properties.
302 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
303 warning, I have verified that this is a bug in the .NET runtime
304 (JavaScript suffers of the same problem).
306 * typemanager.cs (MemberLookup): When looking up members for
307 interfaces, the parent of an interface is the implicit
308 System.Object (so we succeed in searches of Object methods in an
309 interface method invocation. Example: IEnumerable x; x.ToString
312 2002-05-25 Miguel de Icaza <miguel@ximian.com>
314 * class.cs (Event): Events should also register if they do
315 implement the methods that an interface requires.
317 * typemanager.cs (MemberLookup); use the new GetInterfaces
320 (GetInterfaces): The code used to lookup interfaces for a type is
321 used in more than one place, factor it here.
323 * driver.cs: Track the errors at the bottom of the file, we kept
326 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
327 instance if the method we are calling is static!
329 2002-05-24 Miguel de Icaza <miguel@ximian.com>
331 * attribute.cs (ApplyAttributes): Make this function filter out
332 the IndexerName attribute (as that attribute in reality is never
333 applied) and return the string constant for the IndexerName
336 * class.cs (TypeContainer.Emit): Validate that all the indexers
337 have the same IndexerName attribute, and if so, set the
338 DefaultName attribute on the class.
340 * typemanager.cs: The return value might contain other stuff (not
341 only methods). For instance, consider a method with an "Item"
342 property and an Item method.
344 * class.cs: If there is a problem with the parameter types,
347 2002-05-24 Ravi Pratap <ravi@ximian.com>
349 * ecore.cs (ImplicitConversionExists): Wrapper function which also
350 looks at user defined conversion after making a call to
351 StandardConversionExists - we need this for overload resolution.
353 * expression.cs : Update accordingly the various method calls.
355 This fixes 2 bugs filed against implicit user defined conversions
357 2002-05-22 Miguel de Icaza <miguel@ximian.com>
359 * statement.cs: Track the result of the assignment.
361 2002-05-21 Miguel de Icaza <miguel@ximian.com>
363 * expression.cs (MemberAccess): Improved error reporting for
364 inaccessible members.
366 2002-05-22 Martin Baulig <martin@gnome.org>
368 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
369 itself with debugging support.
371 2002-05-22 Martin Baulig <martin@gnome.org>
373 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
374 Removed, this isn't needed anymore.
376 2002-05-20 Martin Baulig <martin@gnome.org>
378 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
379 be underlying type for an enum.
381 2002-05-20 Miguel de Icaza <miguel@ximian.com>
383 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
384 that splits out the loading of just the core types.
386 * rootcontext.cs (ResolveCore): Split the struct resolution in
387 two, so we can load the enumeration underlying types before any
390 * expression.cs (Is): Bandaid until we fix properly Switch (see
391 bug #24985 for details).
393 * typemanager.cs (ImplementsInterface): The hashtable will contain
394 a null if there are no interfaces implemented.
396 2002-05-18 Miguel de Icaza <miguel@ximian.com>
398 * cs-parser.jay (indexer_declarator): It is fine to have array
401 2002-05-17 Miguel de Icaza <miguel@ximian.com>
403 * typemanager.cs: (RegisterBuilder): New function used to register
404 TypeBuilders that implement interfaces. Since
405 TypeBuilder.GetInterfaces (as usual) does not work with lame
407 (AddUserType): register interfaces.
409 (ImplementsInterface): Use the builder_to_ifaces hash if we are
410 dealing with TypeBuilder. Also, arrays are showing up as
411 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
412 methods can not be invoked on them!
414 * ecore.cs (ExplicitReferenceConversionExists): Made public.
415 (ImplicitReferenceConversionExists): Split out from
416 StandardConversionExists.
418 * expression.cs (As): We were only implementing one of the three
419 cases for the as operator. We now implement them all.
420 (Is): Implement the various other cases for Is as well.
422 * typemanager.cs (CACHE): New define used to control if we want or
423 not the FindMembers cache. Seems to have a negative impact on
424 performance currently
426 (MemberLookup): Nested types have full acess to
427 enclosing type members
429 Remove code that coped with instance/static returns for events, we
430 now catch this in RealFindMembers.
432 (RealFindMembers): only perform static lookup if the instance
433 lookup did not return a type or an event.
435 2002-05-17 Miguel de Icaza <miguel@ximian.com>
437 * assign.cs (CompoundAssign): We pass more semantic information
438 now to Compound Assignments than we did before: now we have all
439 the information at hand, and now we resolve the target *before* we
440 do the expression expansion, which allows the "CacheValue" method
441 to have the effect we intended (before, a [x] += 1 would generate
442 two differen ArrayAccess expressions from the ElementAccess,
443 during the resolution process).
445 (CompoundAssign.DoResolve): Resolve target and original_source here.
447 2002-05-16 Miguel de Icaza <miguel@ximian.com>
449 * expression.cs (ArrayAccess): dropped debugging information.
451 * typemanager.cs: Small bug fix: I was always returning i_members,
452 instead of one of i_members or s_members (depending on which had
455 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
456 method is invoked before any code generation takes place, and it
457 is a mechanism to inform that the expression will be invoked more
458 than once, and that the method should use temporary values to
459 avoid having side effects
461 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
463 * ecore.cs (Expression.CacheTemporaries): Provide empty default
466 * expression.cs (Indirection, ArrayAccess): Add support for
467 CacheTemporaries in these two bad boys.
469 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
471 (StoreFromPtr): Handle stobj as well.
473 * expression.cs (UnaryMutator): Share more code.
475 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
476 down: I was not tracking the Filter function as well, which
477 was affecting the results of the cache.
479 2002-05-15 Miguel de Icaza <miguel@ximian.com>
481 * attribute.cs: Remove the hack to handle the CharSet property on
484 2002-05-14 Miguel de Icaza <miguel@ximian.com>
486 * attribute.cs (DoResolve): More uglyness, we now only try to
487 resolve the attribute partially, to extract the CharSet
488 information (only if we are a StructLayout attribute). Otherwise
490 (GetExtraTypeInfo): Add some code to conditionally kill in the
491 future this. I am more and more convinced that the .NET
492 framework has special code to handle the attribute setting on
495 * expression.cs (IsParamsMethodApplicable): Revert my previous
496 foreach change here, it was wrong.
498 2002-05-13 Miguel de Icaza <miguel@ximian.com>
500 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
501 (pp_expr): do not abort on unknown input, just return.
502 (eval): abort if there are pending chars.
504 * attribute.cs (Attribute.Resolve): Positional parameters are
505 optional. Deal with that case.
507 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
508 the Ansi/Unicode/Auto information for the type.
510 (TypeContainer.DefineType): instantiate the EmitContext here, as
511 we will be using it during the type definition (to resolve
512 attributes) and during the emit phase.
514 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
515 to pull type information out of the attributes
517 (Attribute.Resolve): track the constructor builder, and allow for
518 multiple invocations (structs and classes will use this).
520 * ecore.cs (MemberLookupFinal): new version with all the
521 parameters customizable.
523 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
524 constructors. Return if the result value is null (as the error
525 would have been flagged already by MemberLookupFinal)
527 Do not allow instances of abstract classes or interfaces to be
530 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
531 We have to compare the assembly property here when dealing with
532 FamANDAssem and Assembly access modifiers, because we might be
533 creating an assembly from *modules* (that means that we are not
534 getting TypeBuilders for types defined in other modules that are
535 part of this assembly).
537 (Method.Emit): If the method is marked abstract and has a body,
540 (TypeContainer.DefineMembers): If both the defined member and the
541 parent name match are methods, then do not emit any warnings: let
542 the Method.Define routine take care of flagging warnings. But if
543 there is a mismatch (method overrides something else, or method is
544 overriwritten by something, then emit warning).
546 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
547 set to null, this means `do not check for the return type on the
550 (Method.Define): set the return type for the method signature to
551 null, so that we get methods with the same name and parameters and
552 different return types. This is used to flag warning 114 (you are
553 hiding a method, and you probably want to use the new/override
556 * typemanager.cs (MemberLookup): Implemented proper access
557 control, closing a long standing set of bug reports. The problem
558 was that the Framework only has two bits: Public and NonPublic,
559 and NonPublic includes private and protected methods, but we need
560 to enforce the FamANDAssem, FamOrAssem and Family.
562 2002-05-11 Miguel de Icaza <miguel@ximian.com>
564 * statement.cs (GotoCase): Return true: Ammounts to giving up
565 knowledge on whether we return or not, and letting the other case
566 be responsible for it.
568 2002-05-10 Miguel de Icaza <miguel@ximian.com>
570 * driver.cs: Do not load directories for each file processed, only
571 do it if there is a pattern.
573 * ecore.cs: Report readonly assigns here as well, as we might have
574 been resolved only by MemberAccess.
576 (SimpleName.SimpleNameResolve): Also be useful for LValue
577 resolution. We need this to propagate assign to local readonly variables
579 * typemanager.cs: Use a ptrhashtable for the criteria, because we
580 do not want to reuse potential criteria memory.
582 * class.cs (MyEventBuilder): Set reflected_type;
584 * ecore.cs (Constantify): Added support for constifying bools.
586 (RootContext.LookupType): Added a cache for values looked up in
587 the declaration space.
589 * typemanager.cs (FindMembers): Now is a front-end to
590 RealFindMembers, and provides a two-level hashtable-based cache to
593 15% performance improvement: from 22.5 to 19.2 seconds.
595 * expression.cs (IsParamsMethodApplicable): use foreach.
596 (Invocation.DoResolve): ditto.
597 (New.DoResolve): ditto.
598 (ArrayCreation.DoResolve): ditto.
600 * ecore.cs (FindMostEncompassingType): use foreach.
602 * delegate.cs (NewDelegate.DoResolve): Use foreach
604 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
605 (RemoveMethods): use foreach.
607 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
608 nested foreach statements instead of for, and also break out of
609 the inner loop once a match is found.
611 (Invocation.OverloadResolve): Use foreach, simplify the code.
613 2002-05-08 Miguel de Icaza <miguel@ximian.com>
615 * cfold.cs (BinaryFold): During an enumeration evaluation context,
616 we actually unwrap the expression to allow for extra information
619 * expression.cs: Use Shr_Un on unsigned operations.
621 2002-05-08 Ravi Pratap <ravi@ximian.com>
623 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
624 applicable operators was not being considered correctly. This closes
625 the bug Miguel reported.
627 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
629 * attribute.cs: check that the type derives from System.Attribute
630 and report the correct error in that case (moved the duplicate code to
631 its own method, too).
633 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
635 * attribute.cs: lookup attribute type name as the spec says: first the
636 bare attribute name and then name + "Attribute" (nant compiles with
639 2002-05-07 Miguel de Icaza <miguel@ximian.com>
641 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
642 Because of the way we parse things, we should try to see if a
643 UIntConstant can fit in an integer.
645 2002-05-07 Ravi Pratap <ravi@ximian.com>
647 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
648 when we are in an explicit context.
650 (ConvertReferenceExplicit): When converting from Iface type S to Class
651 T make sure the rules are implemented as an OR.
653 * parameter.cs (ParameterType): Make it a property for now although the
654 purpose really isn't anything immediate.
656 * expression.cs (Is*Applicable): Do better checking on the parameter type
657 of a ref/out parameter. The ones from the system assemblies are already
658 marked with the correct type so we don't need to do any correction.
660 * ecore.cs (StandardConversionExists): Conversion from Interface types to
661 the object type is standard too so include that.
663 2002-05-06 Miguel de Icaza <miguel@ximian.com>
665 * ecore.cs (StandardConversionExists): Augment with missing code:
666 deal with IntConstant, LongConstants and Enumerations.
668 * assign.cs: Report the error, instead of failing silently
670 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
671 typecontainer that they are declared, because the
672 typecontainer/namespace will have the list of using clauses that
675 Assembly Attributes were escaping the normal registration
678 (EmitCode): Apply attributes within an EmitContext that represents
679 the container they were declared on.
681 * cs-parser.jay: Track bases for structs. How did I get this wrong?
683 2002-05-06 Ravi Pratap <ravi@ximian.com>
685 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
686 Revamp completely - make much cleaner as we now operate only
689 (FindMostSpecificSource, FindMostSpecificTarget): New methods
690 to implement the logic detailed in the spec more correctly.
692 (UserDefinedConversion): Update accordingly.
694 2002-05-06 Miguel de Icaza <miguel@ximian.com>
696 * statement.cs: Return flow analysis information up.
698 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
701 (token): Do not consume an extra character before calling
704 2002-05-06 Piers Haken <piersh@friskit.com>
706 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
708 2002-05-06 Miguel de Icaza <miguel@ximian.com>
710 * class.cs (Constructor.Emit): Set the IsStatic flag in the
711 EmitContext during the instance constructor initializer
712 resolution, to stop access to instance variables.
714 This is mandated by the spec, last paragraph of the `constructor
715 initializers' section.
717 2002-05-05 Miguel de Icaza <miguel@ximian.com>
719 * cs-parser.jay, class.cs (Accessor): new class used to represent
720 an accessor (get or set). In the past we used `null' to represent
721 a missing accessor. But this is ambiguous because there was no
722 way to tell in abstract indexers/properties if one of them was
725 Now there is a way of addressing that.
727 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
728 instead of FindMembers.
730 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
731 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
733 * attribute.cs: Treat indexers and properties as the same in terms
734 of applying attributes
736 * ecore.cs (FindMostEncompassedType): Use statically initialized
737 EmptyExpressions()s like we do elsewhere to avoid creating useless
738 objects (and we take this out of the tight loop).
740 (GetConversionOperators): Move the code to extract the actual
741 operators to a separate routine to clean things up.
743 2002-05-04 Miguel de Icaza <miguel@ximian.com>
745 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
746 events are always registered FieldBuilders.
748 * class.cs (FieldBase): New class shared by Fields
750 * delegate.cs: If we are a toplevel delegate, use our full name.
751 If we are a nested delegate, then only use our tail name.
753 2002-05-02 Ravi Pratap <ravi@ximian.com>
755 * expression.cs (IsApplicable): Ensure that we add the "&" to
756 ref/out types before comparing it with the type of the argument.
758 (IsParamsMethodApplicable): Ditto.
760 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
763 * delegate.cs : Handle the case when we have more than one applicable
764 method. Flag an error only when we finish checking all.
766 2002-05-02 Miguel de Icaza <miguel@ximian.com>
768 * expression.cs: Add support for boolean static initializers.
770 2002-05-01 Miguel de Icaza <miguel@ximian.com>
772 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
774 * parameter.cs (ComputeParameterTypes,
775 ComputeAndDefineParameterTypes): Better error handling: now we
776 clear the `types' cache if we fail during any of the type lookups.
777 We also return the status code correctly to our caller
779 * delegate.cs: If we fail to define a delegate, abort the extra
782 * expression.cs (Binary.ResolveOperator): for
783 operator==(object,object) and operator !=(object, object) we also
784 have to verify that there is an implicit conversion from one to
787 (ArrayAccess.DoResolve): Array Access can operate on
790 2002-04-30 Miguel de Icaza <miguel@ximian.com>
792 * assign.cs (CompoundAssign): A new class used as a "flag" that
793 the assignment actually is happening as part of a compound
796 During compound assignment, a few new rules exist to enable things
803 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
804 to the type of x) if y is implicitly convertible to the type of x,
805 and the operator is a builtin operator and the return type of the
806 operator is explicitly convertible to the type of x.
808 * rootcontext.cs: Reset warning level to 2. 4 catches various
809 "interesting" features in mcs, we must clean this up at some
810 point, but currently am trying to kill other bugs ;-)
812 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
813 in container classes as well.
815 * expression.cs (Binary.ResolveOperator): Handle string case
816 before anything else (as operator overloading does emit an error
817 before doing anything else).
819 This code could go away when we move to a table driven model, but
820 i could not come up with a good plan last night.
822 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
824 * typemanager.cs (CSharpName): reimplementation using regex.
825 * class.cs: added null check for fields in Emit
826 * rootcontext.cs: set warninglevel to 4
828 2002-04-29 Miguel de Icaza <miguel@ximian.com>
830 * typemanager.cs (CSharpName): reimplemented with Lupus
833 2002-04-28 Miguel de Icaza <miguel@ximian.com>
835 * statement.cs (If): correclty implement Resolve, because we were
836 not catching sem errors in there. The same process is needed
838 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
841 (Statement.Warning_DeadCodeFound): Factorize code.
842 (While): Report dead code here too.
844 (Statement): Added Resolve virtual method to allow
845 for resolution split from the emit code.
847 2002-04-26 Miguel de Icaza <miguel@ximian.com>
849 * statement.cs (EmitBoolExpression): No longer try to resolve the
851 (MakeBoolean): New utility function that resolve, implicitly
852 converts to boolean and tags the expression.
855 (If, Do): Implement dead code elimination.
856 (While): Implement loop inversion
858 (Do, While, For, If): Resolve the expression prior to calling our
861 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
864 - added method Report28 (warning: program has more than one entry point)
865 - added method IsEntryPoint, implements paragraph 10.1 of the spec
866 - modified method Method.Define, the part at the end of the method
868 * rootcontext.cs: added static public Location EntryPointLocation;
870 * ../errors/cs0028.cs : Add test case for the above warning.
873 - modified method CSharpName to allow arrays of primitive type to
874 be printed nicely (e.g. instead of System.Int32[][] it now prints
876 - added method CSharpSignature: returns the signature of a method
877 in string format to be used in reporting errors, warnings, etc.
879 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
882 2002-04-26 Ravi Pratap <ravi@ximian.com>
884 * delegate.cs (Define): Fix extremely silly bug where I was
885 setting the type of the 'object' parameter of the BeginInvoke
886 method to System.IAsyncResult instead of System.Object ;-)
888 2002-04-26 Miguel de Icaza <miguel@ximian.com>
890 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
893 (Constructor.Emit): return if we fail to initialize the
894 constructor. Another door closed!
896 * expression.cs (New.DoResolve): Improve error message (from -6 to
897 1501). Use DeclaredOnly lookup to find the exact constructor.
899 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
900 loop. This is useful.
902 * cs-parser.jay: Adjust the default parameters so that destructors
903 have the proper signature.
905 2002-04-26 Martin Baulig <martin@gnome.org>
907 * driver.cs (LoadAssembly): If `assembly' contains any characters
908 which are only valid in path names and not in assembly names
909 (currently slash, backslash and point), use Assembly.LoadFrom ()
910 instead of Assembly.Load () on the `assembly' (before iteration
911 over the link_paths).
913 2002-04-26 Martin Baulig <martin@gnome.org>
915 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
917 2002-04-25 Miguel de Icaza <miguel@ximian.com>
919 * class.cs (Property): use the new typemanager.MemberLookup
921 (TypeContainer.MemberLookup): Implement using the
922 TypeManager.MemberLookup now.
924 * typemanager.cs: Make MemberLookup a function of the TypeManager,
925 and return MemberInfos, so that these can be used without an
926 EmitContext (what we had before).
928 2002-04-24 Miguel de Icaza <miguel@ximian.com>
930 * expression.cs: Fix the case where the argument to params if the
931 type of the params. I omitted handling this before. Fixed
933 2002-04-22 Miguel de Icaza <miguel@ximian.com>
935 * driver.cs: Call BootCorlib_PopulateCoreType
937 * class.cs (Property.CheckBase): Check for properties only, not
940 * interface.cs: Temporary hack: try/catch around the
941 CustomAttributeBuilder, because I am getting an exception that I
944 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
945 types whose definitions are required to be there (attributes are
946 defined before standard types).
948 Compute definitions as we boot the various types, as they are used
949 immediately (value_type class will need object_type, but if we do
950 not initialize object_type, we will pass a null, which will let
951 the runtime pick the System.Object from the existing corlib, which
952 is not what we want).
954 2002-04-22 Patrik Torstensson <totte@labs2.com>
956 * cs-tokenizer.cs: fixed a number of trim() issues.
958 2002-04-22 Ravi Pratap <ravi@ximian.com>
960 * expression.cs (Argument.Type): Ensure that we return the correct
961 type when we have out or ref parameters [in which case we
964 2002-04-22 Miguel de Icaza <miguel@ximian.com>
966 * class.cs (Property, Indexer): Allow extern modifier in there.
968 * typemanager.cs (InitBaseTypes): Initializes object_type and
969 value_type, since those will be used early on during the bootstrap
970 process to compile corlib.
972 (InitCoreTypes): Move code from here to InitBaseTypes.
974 2002-04-21 Miguel de Icaza <miguel@ximian.com>
976 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
977 single-dimension arrays as using the ldlen opcode.
979 Daniel Lewis discovered this optimization.
981 * typemanager.cs: Add signature for System.Array::get_Length
983 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
985 * statement.cs: report the error when the foreach does not apply to an
986 array nor a collection.
988 2002-04-19 Miguel de Icaza <miguel@ximian.com>
990 * expression.cs: Add implicit conversions to the operator ~.
992 * constant.cs (DecimalConstant.Emit): Emit decimal value.
994 * typemanager.cs: Locate the decimal constructor.
996 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
998 * attribute.cs: use the new property of TypeOf.
999 * expression.cs: added 'get' property around typearg.
1001 These changes fix a build breaker reported by NickD. Is this the
1002 correct way to fix? If not, please, revert my changes and make it
1005 2002-04-17 Miguel de Icaza <miguel@ximian.com>
1007 * attribute.cs: Add support for typeof in attribute invocations.
1008 I am not sure that this is right though.
1010 2002-04-14 Duncan Mak <duncan@ximian.com>
1012 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
1013 Binary.Operator.Division case.
1015 2002-04-13 Ravi Pratap <ravi@ximian.com>
1017 * class.cs (DefineType): Ensure that we do a proper check on
1018 attribute types and also register it with the TypeManager.
1020 (TypeContainer.Targets): The default for attribute types is
1021 AttributeTargets.All.
1023 * attribute.cs (ApplyAttributes): Registering the attribute type
1024 is done elsewhere, not when we discover we have a Usage attribute.
1026 2002-04-12 Ravi Pratap <ravi@ximian.com>
1028 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
1029 and get rid of is_delegate parameter.
1031 * everywhere : update.
1033 2002-04-12 Ravi Pratap <ravi@ximian.com>
1035 * cs-parser.jay (compilation_unit): Revamp completely to use
1036 some new ideas that I got from Rhys' grammar to solve the problems
1037 with assembly level attributes.
1039 (outer_declaration): New grammar production.
1041 (attribute_sections): Add.
1043 (opt_attributes): Base on attribute_sections
1045 (namespace_declaration): Allow opt_attributes to tackle the case
1046 when we have assembly level attributes - we are clever in this
1049 * attribute.cs (ApplyAttributes): Do not worry about assembly
1050 attributes in the non-global context.
1052 * rootcontext.cs (AddGlobalAttributes): Go back to using this
1053 instead of SetGlobalAttributes.
1055 * class.cs, rootcontext.cs : Ensure we define and generate
1056 attribute types before anything else.
1058 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
1059 and flag the new error -20 for the case when the attribute type
1060 does not have valid targets specified. csc does not catch this.
1062 * ../errors/errors.txt : update for error # -20
1064 2002-04-11 Ravi Pratap <ravi@ximian.com>
1066 * support.cs (InternalParameters.ParameterModifier): Do some null
1067 checking and return sane values.
1069 * class.cs (Method.Define): If we are a PInvoke method, ensure
1070 that we are static and extern. Report error # 601
1072 * ../errors/cs0601.cs : Add test case for the above error.
1074 2002-04-07 Ravi Pratap <ravi@ximian.com>
1076 * rootcontext.cs (attribute_types): We need to keep type of
1077 all attribute types separately and emit code for them first.
1079 (RegisterAttribute) : Implement.
1081 * class.cs (DefineType): Check if the current Type is a custom
1082 attribute type and register it accordingly.
1084 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
1085 adding the first attribute twice and rename to
1087 (SetGlobalAttributes): this.
1089 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
1092 * attribute.cs (ApplyAttributes): Take an additional argument telling us
1093 if we are processing global arguments. Hmm, I am unsure of this.
1095 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1097 * expression.cs: added static array of strings to avoid calling
1098 Enum.ToString () for Operator in Binary. Significant recover of
1101 2002-04-10 Miguel de Icaza <miguel@ximian.com>
1103 * class.cs (FindMembers): Allow the Builders of the various
1104 members to be null. If they are skip them. This only happens
1105 during the PInvoke declaration.
1107 2002-04-09 Miguel de Icaza <miguel@ximian.com>
1109 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
1110 failure, so we do not keep going afterwards.
1112 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
1113 wanted to pass `false' as the `is_delegate' argument. If this is
1114 the case, why not use delegate_type == null to mean `is_delegate =
1115 false' and anything else as is_delegate = true.
1117 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
1119 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
1120 code for the section, not the beginning of the tests.
1122 2002-04-08 Miguel de Icaza <miguel@ximian.com>
1124 * cfold.cs: Handle operator + (Enum x, Underlying x)
1126 * expression.cs (Binary): same. Warn about errors where we have
1127 Enum/Enum in operator + as well.
1129 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
1132 - added support for switch(bool)
1133 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
1134 - add TableSwitchEmit() to handle table-based switch statements
1136 2002-04-05 Ravi Pratap <ravi@ximian.com>
1138 * expression.cs (Invocation.OverloadResolve): Factor out code which
1139 does parameter compatibility checking with arguments so that we can
1140 re-use the code even from Delegate.VerifyApplicability
1142 (VerifyArgumentsCompat): Move above code here.
1144 * delegate.cs (VerifyApplicability): Get rid of duplicate code
1145 and instead make a call to the above method.
1147 2002-03-31 Ravi Pratap <ravi@ximian.com>
1149 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
1150 We use it to keep track of classes which are attribute types.
1152 2002-04-02 Miguel de Icaza <miguel@ximian.com>
1154 * delegate.cs (Delegate.Define): Correctly define the types in the
1155 presence of fixed and array parameters.
1157 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
1160 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
1161 include NonPublic after the first iteration.
1163 * class.cs (Indexer.CheckBase): Only check if both parents are
1166 * cs-parser.jay (accessor_body): If empty, set to null.
1168 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
1169 same code path here to resolve constants names that we did have in
1170 MemberAccess.DoResolve. There is too much code duplicated here.
1172 2002-04-01 Miguel de Icaza <miguel@ximian.com>
1174 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
1176 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
1179 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
1180 tokens, numbers and strings.
1182 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
1185 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
1186 asyncronous parameters and the regular parameters.
1188 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
1189 specify the target directory.
1191 * expression.cs: (This.DoResolve): Simplify
1192 (As.Emit): Optimize, do not generate IsInst if the expression is
1193 always of the given type.
1195 (Is.DoResolve): Bug fix, we were reporting both always/never for
1198 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
1199 creating too many unnecessary arrays.
1201 2002-03-31 Miguel de Icaza <miguel@ximian.com>
1203 * class.cs (EmitFieldInitializer): Use Assign expression to assign
1204 fields instead of rolling our own initializer. Takes care of all
1205 implicit conversions, and drops unnecessary static checks/argument.
1207 2002-03-31 Dick Porter <dick@ximian.com>
1209 * driver.cs: use the GetDirectories() return values properly, and
1210 use "/" as path separator.
1212 2002-03-30 Miguel de Icaza <miguel@ximian.com>
1214 * expression.cs (Unary): Optimize - - expr into expr.
1215 (Binary): Optimize a + (-b) into a -b.
1217 * codegen.cs (CodeGen): Made all methods static.
1219 2002-03-29 Miguel de Icaza <miguel@ximian.com>
1223 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
1224 TypeBuilder property.
1226 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
1229 * tree.cs: Removed the various RecordXXXX, and replaced with a
1230 single RecordDecl. Removed all the accessor methods, and just
1231 left a single access point Type
1233 * enum.cs: Rename DefineEnum to DefineType.
1235 * decl.cs: New abstract method `DefineType' used to unify the
1236 Defines for Enumerations, Interfaces, TypeContainers and
1239 (FindType): Moved LookupInterfaceOrClass here. Moved the
1240 LookupBaseClasses method that used to live in class.cs and
1241 interface.cs here, and renamed to FindType.
1243 * delegate.cs: Implement DefineType. Take advantage of the
1244 refactored pattern for locating the parent builder without taking
1245 the parent_builder argument (which we know does not work if we are
1246 nested, and triggering a toplevel definition).
1248 2002-03-28 Miguel de Icaza <miguel@ximian.com>
1250 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
1251 accessibility of a member has changed during override and report
1254 * class.cs (Method.Define, Property.Define): Only complain on
1255 overrides if the method is private, any other accessibility is
1256 fine (and since we just checked the permission is the same, we are
1259 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
1260 and elif are processed always. The other pre-processing
1261 directives are only processed if we are "taking" the path
1263 2002-03-29 Martin Baulig <martin@gnome.org>
1265 * class.cs (Method.Emit): Only emit symbolic debugging info if the
1266 current location is not Null.
1268 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
1269 a separate method so we can profile it.
1271 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
1272 `span.Seconds' are just seconds, but no minutes or hours.
1273 (MainDriver): Profile the CodeGen.SaveSymbols calls.
1275 2002-03-28 Miguel de Icaza <miguel@ximian.com>
1277 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
1278 Remove the gratuitous set of Final:
1280 // If an interface implementation, then we can set Final.
1281 if (((flags & MethodAttributes.Abstract) == 0) &&
1282 implementing.DeclaringType.IsInterface)
1283 flags |= MethodAttributes.Final;
1285 I do not know what I was smoking when I used that.
1288 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
1289 step into fixing the name resolution issues for delegates and
1290 unifying the toplevel name resolution.
1292 2002-03-28 Martin Baulig <martin@gnome.org>
1294 * class.cs (Method.Emit): If we have a symbol writer, call its
1295 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
1296 tell it about the current method.
1298 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
1299 writer that we're going to emit the first byte of IL code for a new
1300 statement (a new source line).
1301 (EmitContext.EmitTopBlock): If we have a symbol writer, call
1302 EmitContext.Mark() before emitting any code.
1304 * location.cs (SymbolDocument): Return null when we're Null.
1306 * statement.cs (Statement): Moved the `Location loc' variable here.
1307 (Statement.EmitBoolExpression): If we have a symbol writer, call
1308 ec.Mark() before emitting any code to tell it that we're at the
1309 beginning of a new statement.
1310 (StatementExpression): Added `Location' argument to the constructor.
1311 (Block): Added public readonly variable `StartLocation' and public
1312 variable `EndLocation'. The latter is to be set using SetEndLocation().
1313 (Block): Added constructor which takes a start and end location.
1314 (Block.SetEndLocation): New method. This sets the end location.
1315 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
1316 local variables we create.
1317 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
1318 each statement and do also mark the begin and end of the block.
1320 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
1321 tell it the current lexer.Location, use Location.Null for the end of the
1323 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
1324 current block, set its end location using SetEndLocation().
1325 (statement_expression): StatementExpression constructor now takes the
1326 lexer.Location as additional argument.
1327 (for_statement, declare_local_variables): Likewise.
1328 (declare_local_variables): When creating a new implicit block, use the
1329 new Block constructor and pass it the lexer.Location.
1331 2002-03-28 Miguel de Icaza <miguel@ximian.com>
1333 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
1334 members also on the parent interfaces recursively.
1336 2002-03-27 Miguel de Icaza <miguel@ximian.com>
1338 * report.cs: Use new formats, since Gonzalo finished the missing
1341 * expression.cs (Binary.ResolveOperator): added missing operator|
1342 operator& and operator^ for bool/bool.
1344 * cs-parser.jay: CheckDef now takes a Location argument that is
1345 used to report errors more precisly (instead of reporting the end
1346 of a definition, we try to track something which is a lot closer
1347 to the source of the problem).
1349 * cs-tokenizer.cs: Track global token use, so we can properly flag
1350 the use of #define/#undef after the first token has been seen.
1352 Also, rename the reportXXXX to Error_DescriptiveName
1354 * decl.cs (DeclSpace.IsTopLevel): Move property here from
1355 TypeContainer, so that Enum and Interface can use this too.
1357 * class.cs (TypeContainer.LookupInterfaceOrClass,
1358 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
1359 `builder' argument. Typically this was used to pass the parent
1360 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
1363 The problem is that a nested class could trigger the definition of
1364 a toplevel class, and the builder would be obviously wrong in that
1367 So we drop this argument, and we compute dynamically the
1368 TypeBuilder/ModuleBuilder (the correct information was available
1369 to us anyways from DeclSpace.Parent)
1371 * interface.cs (Interface.DefineInterface): Drop builder
1372 parameter cleanup like class.cs
1374 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
1377 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
1380 (Try.Emit): Propagate the returns value from the statement.
1382 (Return.Emit): Even if we are leavning
1384 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
1386 * modifiers.cs: Fix the computation of MethodAttributes flags.
1388 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
1390 * driver.cs: allow compilation of files that start with '/'.
1391 Add a default case when checking the argument of --target.
1393 2002-03-25 Miguel de Icaza <miguel@ximian.com>
1395 * interface.cs: Implement the same search algorithm for types in
1398 * delegate.cs: Do not allow multiple definition.
1400 * Recovered ChangeLog that got accidentally amputated
1402 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
1404 * rootcontext.cs: Load manually enum to allow core classes to
1405 contain enumerations.
1407 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
1408 Update to new static methods in TypeManager.
1410 * typemanager.cs (GetMethod, GetConstructor): Use our
1411 implementation of FindMembers to find the members, since during
1412 corlib compilation, the types are TypeBuilders and GetMethod and
1413 GetConstructor do not work.
1415 Make all methods in TypeManager static.
1417 (InitCodeHelpers): Split the functionality from
1418 the InitCodeTypes function.
1420 * driver.cs: Call InitCodeHelpers after we have populated the
1423 * cs-parser.jay (delegate_declaration): we did not used to compute
1424 the delegate name correctly for void delegates.
1426 2002-03-24 Miguel de Icaza <miguel@ximian.com>
1428 * rootcontext.cs (RootContext): Init the interface_resolve_order
1429 and type_container_resolve_order always.
1431 (ResolveCore, BootstrapCorlib_ResolveClass,
1432 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
1433 compiler when compiling with --nostdlib
1435 * class.cs (TypeContainer.DefineType): Check that our parent is
1436 not null. This test is most important when we are bootstraping
1439 * codegen.cs: Split out the symbol writing code.
1441 2002-03-25 Martin Baulig <martin@gnome.org>
1443 * driver.cs (-g): Made -g an alias for --debug.
1445 2002-03-24 Martin Baulig <martin@gnome.org>
1447 * codegen.cs (SymbolWriter): New public variable. Returns the
1448 current symbol writer.
1449 (CodeGen): Added `bool want_debugging_support' argument to the
1450 constructor. If true, tell the ModuleBuild that we want debugging
1451 support and ask it for the ISymbolWriter.
1452 (Save): If we have a symbol writer, call it's Close() method after
1453 saving the assembly.
1455 * driver.c (--debug): New command line argument to create a
1456 debugger information file.
1458 * location.cs (SymbolDocument): New public property. Returns an
1459 ISymbolDocumentWriter object for the current source file or null
1460 if we don't have a symbol writer.
1462 2002-03-21 Miguel de Icaza <miguel@ximian.com>
1464 * driver.cs (LoadAssembly): Correctly return when all the paths
1465 have been tried and not before.
1467 * statement.cs (Switch.Emit): return the actual coverage for this
1468 statement (returns/not-returns)
1470 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
1471 switch of the statement if we are the last switch section. That
1472 kills two problems: try/catch problems (we used to emit an empty
1473 nop at the end) and switch statements where all branches would
1476 2002-03-19 Miguel de Icaza <miguel@ximian.com>
1478 * driver.cs: Add default assemblies (the equivalent to the
1479 Microsoft CSC.RSP file)
1481 * cs-tokenizer.cs: When updating `cols and setting it to zero,
1482 also update tokens_seen and set it to false.
1484 * driver.cs: Implement --recurse for Mike.
1486 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
1487 correctly splitting out the paths.
1489 2002-03-18 Miguel de Icaza <miguel@ximian.com>
1491 * interface.cs (Interface.PopulateProperty): Instead of using
1492 `parent' as the declaration space for the set parameters, use
1495 * support.cs (InternalParameters): InternalParameters constructor
1496 takes a DeclSpace instead of a TypeContainer.
1498 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
1499 types are being initialized, load the address of it before calling
1502 (New): Provide a mechanism to disable the generation of local
1503 value type temporaries when the caller will be providing us with
1504 an address to store it.
1506 (ArrayCreation.EmitDynamicInitializers): Use it.
1508 2002-03-17 Miguel de Icaza <miguel@ximian.com>
1510 * expression.cs (Invocation.EmitArguments): Only probe for array
1511 property if there is more than one argument. Sorry about that.
1513 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
1516 * class.cs (Method.LabelParameters): Fix incorrect code path that
1517 prevented the `ParamArrayAttribute' from being applied to the
1520 2002-03-16 Miguel de Icaza <miguel@ximian.com>
1522 * support.cs (ReflectionParameters): Correctly compute whether the
1523 last argument is a params array. Fixes the problem with
1526 * typemanager.cs: Make the assemblies array always be non-null
1527 (empty, but non-null)
1529 * tree.cs (RecordDecl): New function that abstracts the recording
1530 of names. This reports error 101, and provides a pointer to the
1531 previous declaration. Fixes a crash in the compiler.
1533 * cs-parser.jay (constructor_declaration): Update to new grammar,
1534 and provide a constructor_body that can be empty.
1536 2002-03-15 Miguel de Icaza <miguel@ximian.com>
1538 * driver.cs: Add support for --resources.
1540 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
1541 Make all types for the various array helper methods be integer.
1543 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
1544 CheckState to ConvCast.
1546 (ConvCast): Now it takes a `checked' state argument, to avoid
1547 depending on the emit context for the conversion, and just using
1548 the resolve time setting.
1550 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
1551 instead of Invocation.EmitArguments. We do not emit the original
1552 arguments, instead we emit those which have been converted to
1553 unsigned int expressions.
1555 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
1557 * codegen.cs: ditto.
1559 * expression.cs (LocalVariableReference): Drop the use of the
1560 Store function that depended on the variable index.
1562 * statement.cs (VariableInfo): Drop the `Idx' property from this
1563 class, as this is not taking into account the indexes for
1564 temporaries tat we generate during the execution, getting the
1567 * class.cs: First emit class initializers, then call the parent
1570 * expression.cs (Binary): Fix opcode emision.
1571 (UnaryMutator.EmitCode): Support checked code generation
1573 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
1574 matches for events for both the Static and Instance scans,
1575 pointing to the same element. Fix that.
1577 2002-03-14 Miguel de Icaza <miguel@ximian.com>
1579 * rootcontext.cs (ResolveTree): Always set the
1580 interface_resolve_order, because nested interfaces will be calling
1583 * class.cs (GetInterfaceOrClass): Track the same resolution
1584 process used by TypeManager.LookupType. This fixes the nested
1585 type lookups in class declarations (separate path from
1588 (TypeContainer.DefineType): Also define nested interfaces.
1589 (TypeContainer.RegisterOrder): New public function used to
1590 register the order in which child interfaces need to be closed.
1592 Nested interfaces need to be closed after their parents have been
1595 * interface.cs (InterfaceAttr): Put all the logic for computing
1596 the interface attribute here.
1598 (DefineInterface): Register our interface order with the
1599 RootContext or with the TypeContainer depending on the case.
1601 2002-03-12 Miguel de Icaza <miguel@ximian.com>
1603 * cs-parser.jay: rework foreach statement to work with the new
1604 changes to the policy on SimpleNames.
1606 * report.cs: support Stacktrace on warnings as well.
1608 * makefile: drop --unsafe and /unsafe from the compile.
1610 2002-03-13 Ravi Pratap <ravi@ximian.com>
1612 * ecore.cs (StandardConversionExists): Modify to take an Expression
1613 as the first parameter. Ensure we do null -> reference type conversion
1616 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
1617 temporary Expression objects.
1619 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
1621 * interface.cs: workaround bug in method overloading resolution
1622 (there is already a bugzilla bug for it).
1624 2002-03-12 Miguel de Icaza <miguel@ximian.com>
1626 We could also solve this problem by having a separate path for
1627 performing type lookups, instead of DoResolve, we could have a
1628 ResolveType entry point, and only participating pieces of the
1629 production (simplename, deref, array) would implement this.
1631 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
1632 signal SimpleName to only resolve type names and not attempt to
1633 resolve anything else.
1635 * expression.cs (Cast): Set the flag.
1637 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
1639 * class.cs: Only report 108 if there is no `new' modifier.
1641 * cs-parser.jay: rework foreach statement to work with the new
1642 changes to the policy on SimpleNames.
1644 * report.cs: support Stacktrace on warnings as well.
1646 * makefile: drop --unsafe and /unsafe from the compile.
1648 2002-03-11 Miguel de Icaza <miguel@ximian.com>
1650 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
1651 lookups here, instead of doing that at parse time. This means
1652 that our grammar will not introduce `LocalVariableReferences' as
1653 expressions at this point. That solves the problem of code like
1661 This is only half the fix. The full fix requires parameters to
1662 also be handled in this way.
1664 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
1665 makes the use more obvious of the DeclSpace. The
1666 ec.TypeContainer.TypeBuilder is now only used to pull the
1669 My theory is that I can get rid of the TypeBuilder completely from
1670 the EmitContext, and have typecasts where it is used (from
1671 DeclSpace to where it matters).
1673 The only pending problem is that the code that implements Aliases
1674 is on TypeContainer, and probably should go in DeclSpace.
1676 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
1677 lookups here, instead of doing that at parse time. This means
1678 that our grammar will not introduce `LocalVariableReferences' as
1679 expressions at this point. That solves the problem of code like
1687 This is only half the fix. The full fix requires parameters to
1688 also be handled in this way.
1690 * class.cs (Property.DefineMethod): When implementing an interface
1691 method, set newslot, when implementing an abstract method, do not
1692 set the flag (before we tried never setting it, or always setting
1693 it, which is the difference).
1694 (Indexer.DefineMethod): same.
1695 (Method.DefineMethod): same.
1697 * ecore.cs: Only set the status used flag if we get back a Field.
1699 * attribute.cs: Temporary hack, so Paolo can keep working.
1701 2002-03-08 Ravi Pratap <ravi@ximian.com>
1703 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
1704 the unmanaged type in the case we have a MarshalAs attribute.
1706 (Resolve): Handle the case when we are parsing the special MarshalAs
1707 attribute [we need to store the unmanaged type to use later]
1709 * typemanager.cs (marshal_as_attr_type): Built in type for the
1710 MarshalAs Attribute.
1712 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
1713 on parameters and accordingly set the marshalling info.
1715 2002-03-09 Miguel de Icaza <miguel@ximian.com>
1717 * class.cs: Optimizing slightly by removing redundant code after
1718 we switched to the `NoTypes' return value.
1719 (Property.DefineMethod): use NoTypes here too.
1721 This fixes the bug I introduced in my last batch of changes.
1723 2002-03-05 Ravi Pratap <ravi@ximian.com>
1725 * tree.cs (RecordEnum): Add. We now keep track of enums too.
1727 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
1728 Enums since those are types too.
1730 * cs-parser.jay (enum_declaration): Record enums as we parse them.
1732 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
1733 thanks to a call during the lookup process.
1735 2002-03-07 Miguel de Icaza <miguel@ximian.com>
1737 * statement.cs (Foreach): Lots of work to accomodate a particular
1738 kind of foreach statement that I had not kept in mind. It is
1739 possible to have foreachs on classes that provide a GetEnumerator
1740 method that return objects that implement the "pattern" for using
1741 a foreach, there is no need to support GetEnumerator
1744 This is needed to compile nant.
1746 * decl.cs: Only report 114 if the member is not `Finalize' and if
1747 the warning level is at least 2.
1749 * class.cs: Moved the compare function from Method to
1752 (MethodSignature.InheritableMemberSignatureCompare): Add new
1753 filter function that is used to extract inheritable methods from a
1756 (Method.Define): Use the new `inheritable_method_signature_filter'
1759 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
1762 2002-03-06 Miguel de Icaza <miguel@ximian.com>
1764 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
1766 * cs-parser.jay: Add opt_semicolon to the interface declaration.
1768 * expression.cs: Pass location information to
1769 ConvertImplicitStandard.
1771 * class.cs: Added debugging code to track return values from
1774 2002-03-05 Miguel de Icaza <miguel@ximian.com>
1776 * expression.cs (Is.DoResolve): If either side of the `is' is an
1777 interface, do not flag the warning.
1779 * ecore.cs (ImplicitReferenceConversion): We need a separate test
1782 * report.cs: Allow for --fatal to be used with --probe.
1784 * typemanager.cs (NoTypes): Move the definition for the empty Type
1787 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
1789 (TypeContainer.DefineProxy): New function used to proxy to parent
1790 implementations when implementing interfaces.
1791 (TypeContainer.ParentImplements): used to lookup if our parent
1792 implements a public function that is required by an interface.
1793 (TypeContainer.VerifyPendingMethods): Hook this up.
1795 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
1796 `modules' and `assemblies' arraylists into arrays. We only grow
1797 these are the very early start up of the program, so this improves
1798 the speedof LookupType (nicely measured).
1800 * expression.cs (MakeByteBlob): Replaced unsafe code with
1801 BitConverter, as suggested by Paolo.
1803 * cfold.cs (ConstantFold.Binary): Special case: perform constant
1804 folding of string concatenation, but if either side is a string,
1805 and the other is not, then return null, and let the runtime use
1806 the concatenation on the string plus the object (using
1809 2002-03-04 Miguel de Icaza <miguel@ximian.com>
1811 Constant Folding has been implemented now.
1813 * expression.cs (Unary.Reduce): Do not throw an exception, catch
1814 the error instead on types that are not supported in one's
1817 * constant.cs (Constant and all children): New set of functions to
1818 perform implict and explicit conversions.
1820 * ecore.cs (EnumConstant): Implement the new functions to perform
1821 conversion by proxying to the child expression.
1823 * codegen.cs: (ConstantCheckState): Constant evaluation has its
1824 own separate setting that can not be turned off from the command
1825 line using --unchecked or --checked and is only controlled using
1826 the checked/unchecked statements and expressions. This setting is
1827 used by the constant folder to flag errors.
1829 * expression.cs (CheckedExpr, UncheckedExpr): Set the
1830 ConstantCheckState as well.
1832 During Resolve, they also have to flag the state, because the
1833 constant folder runs completely in the Resolve phase.
1835 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
1838 2002-03-01 Miguel de Icaza <miguel@ximian.com>
1840 * cfold.cs: New file, this file contains the constant folder.
1842 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
1843 argument to track whether we are using the resulting address to
1844 load or store a value and provide better error messages.
1846 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
1847 new AddressOf arguments.
1849 * statement.cs (Foreach.EmitCollectionForeach): Update
1851 * expression.cs (Argument.Emit): Call AddressOf with proper
1852 arguments to track usage.
1854 (New.DoEmit): Call AddressOf with new arguments.
1856 (Unary.Emit): Adjust AddressOf call.
1858 2002-03-01 Ravi Pratap <ravi@ximian.com>
1860 * cs-parser.jay (member_access): Change the case for pre-defined types
1861 to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
1864 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
1867 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
1868 essentially like methods and apply attributes like MethodImplOptions to them too.
1870 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
1873 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
1874 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
1877 * Update code everywhere accordingly.
1879 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
1881 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
1883 2002-02-28 Ravi Pratap <ravi@ximian.com>
1885 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
1886 try performing lookups against those instead of jumping straight into using
1887 the 'using' clauses.
1889 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
1891 (LookupType): Perform lookups in implicit parents too.
1893 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
1894 sequence as RootContext.LookupType.
1896 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
1897 the various cases of namespace lookups into this method.
1899 2002-03-01 Miguel de Icaza <miguel@ximian.com>
1901 * cs-parser.jay: Add support for [Attribute ()] (empty arguments
1902 in positional arguments)
1904 * class.cs (Operator): Update the AllowedModifiers to contain
1907 * cs-parser.jay: Update operator declaration to allow for the
1908 operator body to be empty.
1910 * cs-tokenizer.cs: Added '\u' unicode support in strings and hex
1913 2002-02-27 Miguel de Icaza <miguel@ximian.com>
1915 * class.cs (Method.Emit): Label parameters.
1917 * driver.cs: Return 1 or 0 as the program exit code.
1919 2002-02-26 Miguel de Icaza <miguel@ximian.com>
1921 * expression.cs: Special case the `null' object when trying to
1922 auto-compute the type, as anything can be explicitly converted to
1925 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
1926 spotting this Paolo.
1928 (Expression.ImplicitNumericConversion): Perform comparissions of
1929 the type using the underlying type in the case of an enumeration
1930 rather than using the enumeration type for the compare.
1932 Cope with the underlying == type case, which is not possible to
1935 (Expression.ConvertNumericExplicit): Perform comparissions of
1936 the type using the underlying type in the case of an enumeration
1937 rather than using the enumeration type for the compare.
1939 * driver.cs: If the user does not supply an extension, assume .exe
1941 * cs-parser.jay (if_statement): Rewrote so that we can track the
1942 location for the if statement.
1944 * expression.cs (Binary.ConstantFold): Only concat strings when
1945 the operation is "+", not everything ;-)
1947 * statement.cs (Statement.EmitBoolExpression): Take a location
1949 (If, While, Do): Track location.
1951 * expression.cs (Binary.ResolveOperator): In the object + string
1952 case, I was missing a call to ConvertImplicit
1954 2002-02-25 Ravi Pratap <ravi@ximian.com>
1956 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
1957 Location arguments. Ensure we use RootContext.LookupType to do our work
1958 and not try to do a direct Type.GetType and ModuleBuilder.GetType
1960 * interface.cs (PopulateMethod): Handle the type of the parameter being
1963 * expression.cs (Invocation.BetterFunction): Handle the case when we
1964 have a params method with no fixed arguments and a call is made with no
1967 2002-02-25 Miguel de Icaza <miguel@ximian.com>
1969 * cs-tokenizer.cs: Add support for the quote-escape-sequence in
1970 the verbatim-string-literal
1972 * support.cs (InternalParameters.ParameterModifier): handle null
1974 (InternalParameters.ParameterType): ditto.
1976 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
1977 duplicating the name of the variable parameter.
1978 (GetParameterByName): Fix bug where we were not looking up array
1979 paramters if they were the only present (thanks Paolo!).
1980 (GetParameterInfo): We only have an empty set of types if both
1981 fixed and array are set to null.
1982 (GetParameterInfo-idx): Handle FixedParameter == null
1984 * cs-parser.jay: Handle the case where there is no catch
1985 statements (missing null test).

1989 * driver.cs (MainDriver): Be conservative on our command line
1992 Catch DirectoryNotFoundException when calling GetFiles.
1994 (SplitPathAndPattern): Used to split the input specification into
1995 a path and a pattern that we can feed to Directory.GetFiles.

1999 * statement.cs (Fixed): Implement the last case of the Fixed
2000 statement (string handling).

2003 a string; Used by the Fixed statement.
2005 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
2007 * expression.cs (Binary.ResolveOperator): Remove redundant
2008 MemberLookup pn parent type.
2009 Optimize union call, we do not need a union if the types are the same.
2010 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
2013 Specialize the use of MemberLookup everywhere, instead of using
2014 the default settings.
2016 (StackAlloc): Implement stackalloc keyword.
2018 * cs-parser.jay: Add rule to parse stackalloc.
2020 * driver.cs: Handle /h, /help, /?

2032 Handle pointer comparission.
2033 (ArrayPtr): Utility expression class that is used to take the
2034 address of an array.
2036 (ElementAccess): Implement array access for pointers
2038 * statement.cs (Fixed): Implement fixed statement for arrays, we
2039 are missing one more case before we are done.
2041 * expression.cs (Indirection): Implement EmitAssign and set the
2042 ExprClass to Variable. This allows pointer dereferences to be
2043 treated as variables, and to have values assigned to them.
2045 * ecore.cs (Expression.StoreFromPtr): New utility function to
2046 store values dereferencing.
2048 2002-02-20 Ravi Pratap <ravi@ximian.com>
2050 * expression.cs (Binary.ResolveOperator): Ensure that we are
2051 not trying to operate on a void type - this fixes the reported
2054 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
2055 the parent implementation is sealed.
2057 * ../errors/cs0239.cs : Add.
2059 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
2061 * typemanager.cs (unverifiable_code_type): Corresponds to
2062 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
2063 which have unsafe code in them.
2065 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
2068 2002-02-19 Miguel de Icaza <miguel@ximian.com>
2070 * cs-tokenizer.cs: Add support for @"litreal strings"

2084 * expression.cs (Indirection): New helper class. Unary will
2085 create Indirection classes to be able to implement the
2086 IMemoryLocation interface on it.

2093 statement for the &x case.
2095 2002-02-14 Miguel de Icaza <miguel@ximian.com>
2097 * class.cs (Property.Define, Method.Define): Remove newslot when
2100 * modifiers.cs: My use of NewSlot when `Abstract' was set was
2101 wrong. NewSlot should only be used if the `new' keyword is present.
2103 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
2104 locating our system dir. Sorry about this.
2106 2002-02-13 Miguel de Icaza <miguel@ximian.com>
2108 * driver.cs (GetSystemDir): Compute correctly the location of our
2109 system assemblies. I was using the compiler directory instead of
2110 the library directory.
2112 2002-02-13 Ravi Pratap <ravi@ximian.com>
2114 * expression.cs (BetterFunction): Put back in what Miguel commented out
2115 since it is the correct fix. The problem is elsewhere ;-)
2117 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
2118 parameters of the parms method are themselves compatible or not !
2120 (StandardConversionExists): Fix very dangerous bug where we were forgetting
2121 to check that a class implements an interface before saying that an implicit
2122 conversion was allowed. Use ImplementsInterface to do the checking.
2124 2002-02-13 Miguel de Icaza <miguel@ximian.com>
2126 * class.cs (Method.Define): Track whether we are an explicit
2127 implementation or not. And only call DefineMethodOverride if we
2128 are an explicit implementation.
2130 (Property.DefineMethod): Ditto.
2132 2002-02-11 Ravi Pratap <ravi@ximian.com>
2134 * expression.cs (BetterFunction): Catch hideous bug which was
2135 preventing us from detecting ambiguous calls due to implicit casts i.e
2138 2002-01-29 Miguel de Icaza <miguel@ximian.com>
2140 * support.cs (Pair): Remove un-needed method. I figured why I was
2141 getting the error in cs-parser.jay, the variable in a foreach loop
2142 is readonly, and the compiler does not really treat this as a variable.
2144 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
2145 instead of EQUALS in grammar.
2147 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
2149 * expression.cs (Unary.DoResolve): Check whether the argument is
2152 2002-01-28 Miguel de Icaza <miguel@ximian.com>
2154 * support.cs: Api for Pair to set a value. Despite the fact that
2155 the variables are public the MS C# compiler refuses to compile
2156 code that accesses the field if the variable is part of a foreach
2159 * statement.cs (Fixed): Begin implementation of the fixed
2162 (Block.AddVariable): Return the VariableInfo on success and null
2163 on failure instead of true/false.
2165 * cs-parser.jay (foreach): Catch errors on variables already
2166 defined (we were ignoring this value before) and properly unwind
2169 (fixed_statement): grammar for the fixed statement.
2171 2002-01-25 Miguel de Icaza <miguel@ximian.com>
2173 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
2174 pointer types to be incretemented.

2188 use in non-unsafe context).
2190 (SimpleName.DoResolve): Check for pointers in field access on safe
2193 (Expression.LoadFromPtr): Factor the load-indirect code in this
2194 function. This was duplicated in UnboxCast and ParameterReference
2196 2002-01-24 Miguel de Icaza <miguel@ximian.com>
2198 * expression.cs (ComposedCast): report an error if a pointer cast
2199 is used in a safe region.
2201 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
2202 pointer type casts in unsafe context.
2204 * codegen.cs (EmitContext): Set up IsUnsafe.
2206 * cs-parser.jay (non_expression_type): Add productions for pointer
2209 * expression.cs (Invocation.EmitCall): Remove chunk of buggy
2210 code. We should not use force into static mode if the method is
2211 not virtual. Fixes bug in MIS
2213 * statement.cs (Do.Emit, While.Emit, For.Emit,
2214 Statement.EmitBoolExpression): Add support to Do and While to
2215 propagate infinite loop as `I do return' semantics.
2217 Improve the For case to also test for boolean constants.
2219 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
2220 to the list of attributes we can add.
2222 Remove `EmitContext' argument.
2224 * class.cs (Method.Define): Apply parameter attributes.
2225 (Constructor.Define): Apply parameter attributes.
2226 (MethodCore.LabelParameters): Move here the core of labeling
2229 * support.cs (ReflectionParameters.ParameterModifier,
2230 InternalParameters.ParameterModifier): Use IsByRef on the type and
2231 only return the OUT bit for these parameters instead of in/out/ref
2234 This is because I miss-understood things. The ParameterInfo.IsIn
2235 and IsOut represent whether the parameter has the [In] and [Out]
2238 2002-01-22 Miguel de Icaza <miguel@ximian.com>
2240 * ecore.cs (FieldExpr.Emit): Release temporaries.
2242 * assign.cs (LocalTemporary.Release): new function.
2244 * codegen.cs (EmitContext.GetTemporaryStorage,
2245 EmitContext.FreeTemporaryStorage): Rework the way we deal with
2246 temporary storage. Now we can "put back" localbuilders when we
2249 2002-01-21 Miguel de Icaza <miguel@ximian.com>
2251 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
2252 need to make a copy of the variable to generate verifiable code.
2254 2002-01-19 Miguel de Icaza <miguel@ximian.com>
2256 * driver.cs: Compute dynamically the system directory.
2258 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
2259 Slower, but more generally useful. Used by the abstract
2260 registering implementation.
2262 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
2263 the rules for the special rule on Type/instances. First check if
2264 we have the same name, and if so, try that special static path
2265 rather than the instance path.
2267 2002-01-18 Miguel de Icaza <miguel@ximian.com>
2269 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
2272 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
2273 Enum, ValueType, Delegate or Array for non-corlib compiles.
2275 * cs-tokenizer.cs: Catch long identifiers (645)
2277 * typemanager.cs (IndexerPropetyName): Ravi never tested this
2280 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
2281 fix, we were returning too early, so we were not registering
2282 pending methods from abstract classes.
2284 Do not register pending methods if the class is abstract.
2286 * expression.cs (Conditional.DoResolve): Report circular implicit
2287 conversions when we neecd to compute it for conditional
2290 (Is.DoResolve): If the expression is always of the provided type,
2291 flag warning 183. If the expression can not ever be of the
2292 provided type flag warning 184.
2294 * class.cs: Catch 169 as well.
2296 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
2299 2002-01-18 Nick Drochak <ndrochak@gol.com>
2301 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.
2303 2002-01-17 Miguel de Icaza <miguel@ximian.com>
2305 * interface.cs: (PopulateMethod): Check for pointers being defined
2306 only if the unsafe context is active.
2307 (PopulateProperty): ditto.
2308 (PopulateIndexer): ditto.
2310 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
2311 specified. If pointers are present, make sure that they are
2312 present in an unsafe context.
2313 (Constructor, Constructor.Define): ditto.
2314 (Field, Field.Define): ditto.
2315 (Property, Property.Define): ditto.
2316 (Event, Event.Define): ditto.
2318 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
2319 hashtable if there are classes or structs defined.
2321 * expression.cs (LocalVariableReference.DoResolve): Simplify this
2322 code, as the constant resolution moved.
2324 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
2325 the metadata, so we can flag error 133.
2327 * decl.cs (MemberCore.UnsafeOK): New function to test that a
2328 pointer is being declared in an unsafe context.
2330 2002-01-16 Miguel de Icaza <miguel@ximian.com>
2332 * modifiers.cs (Modifiers.Check): Require a Location argument.
2333 Report error 227 for Unsafe use.
2335 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
2337 * statement.cs (For.Emit): If the test is null, then report that
2338 we do `return', as we wont reach anything afterwards.
2340 (Switch.SwitchGoverningType): Track the expression that matched
2343 * driver.cs: Allow negative numbers as an error code to flag.
2345 * cs-parser.jay: Handle 1551.
2347 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
2349 2002-01-15 Miguel de Icaza <miguel@ximian.com>
2351 * cs-parser.jay: Report 1518 (type declaration can only contain
2352 class, struct, interface, enum or delegate)
2354 (switch_label): Report 1523 (keywords `case' or `default' must
2357 (opt_switch_sections): Report 1522 (empty switch)
2359 * driver.cs: Report 1515 (response file specified multiple times)
2360 Report 1516 (Source file specified multiple times).
2362 * expression.cs (Argument.Resolve): Signal 1510
2364 (BaseAccess.Resolve, BaseIndexer.Resolve): Signal 1511 (base
2365 access not allowed in static code)
2367 2002-01-11 Ravi Pratap <ravi@ximian.com>
2369 * typemanager.cs (IsPointerType): Utility method which we are going
2372 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
2373 the object type, so we take care of that.
2375 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
2377 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
2378 added to non-params parameters :-)
2380 * typemanager.cs (CSharpName): Include 'void' type too.
2382 (void_ptr_type): Include in the set of core types.
2384 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
2387 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
2390 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
2391 completely forgotten about it.
2393 2002-01-10 Ravi Pratap <ravi@ximian.com>
2395 * cs-parser.jay (pointer_type): Add. This begins our implementation
2396 of parsing rules for unsafe code.
2398 (unsafe_statement): Implement.
2400 (embedded_statement): Modify to include the above.
2402 * statement.cs (Unsafe): Implement new class for unsafe blocks.
2404 * codegen.cs (EmitContext.InUnsafe): Add. This determines
2405 if the current context is an unsafe one.
2407 * cs-parser.jay (local_variable_pointer_type): Since local variable types
2408 are handled differently, we need separate rules for them.
2410 (local_variable_declaration): Update to use local_variable_pointer_type
2411 to allow variable declarations of unmanaged pointer types.
2413 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
2416 * ../errors/cs0214.cs : Add.
2418 2002-01-16 Nick Drochak <ndrochak@gol.com>

2428 * typemanager.cs (RegisterMethod): drop checking if we have
2429 registered this from here
2431 2002-01-12 Miguel de Icaza <miguel@ximian.com>
2433 * class.cs (Method.EmitDestructor): Implement calling our base
2436 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
2439 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
2440 this routine and will wrap the call in a try/catch block. Deal
2443 2002-01-11 Miguel de Icaza <miguel@ximian.com>
2445 * ecore.cs (Expression.MemberLookup): instead of taking a
2446 parameter `same_type' that was used to tell whether we could
2447 access private members we compute our containing type from the
2450 (FieldExpr): Added partial support for volatile fields. This does
2451 not work for volatile fields exposed from assemblies, as I can not
2452 figure out how to extract the modreq from it.
2454 Updated all the source files to use this.
2456 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
2457 because it is referenced by MemberLookup very often.
2459 2002-01-09 Ravi Pratap <ravi@ximian.com>
2461 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
2462 TypeBuilder.GetCustomAttributes to retrieve what we need.
2464 Get rid of redundant default_member_attr_type as this is the same as
2465 default_member_type which already exists.
2467 * interface.cs, attribute.cs : Update accordingly.
2469 2002-01-08 Miguel de Icaza <miguel@ximian.com>
2471 * typemanager.cs: Enable IndexerPropertyName again. It does not
2472 work for TYpeBuilders though. Ravi, can you please fix this?
2474 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
2476 * expression.cs (Argument.Emit): Handle the case of ref objects
2477 being passed to ref functions;
2479 (ParameterReference.EmitLoad): Loads the content of the pointer
2480 without dereferencing.
2482 2002-01-07 Miguel de Icaza <miguel@ximian.com>
2484 * cs-tokenizer.cs: Implemented the pre-processing expressions.
2486 2002-01-08 Ravi Pratap <ravi@ximian.com>
2488 * class.cs (Indexer.DefineMethod): Incorporate the interface
2489 type in the name of the method if we are doing explicit interface
2492 * expression.cs (ConversionExists): Remove as it is completely obsolete.
2494 (BetterConversion): Fix extremely trivial bug where we were referring to
2495 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
2498 * ../errors/bug16.cs : Add although we have fixed it.
2500 2002-01-07 Miguel de Icaza <miguel@ximian.com>
2502 * expression.cs (BaseIndexer): Begin implementation.
2504 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
2506 * cs-parser.jay (indexer_declarator): Use qualified_identifier
2507 production directly to remove a shift/reduce, and implement
2508 explicit interface implementation.
2510 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
2511 after a floating point suffix.
2513 * expression.cs (DoNumericPromotions): Improved the conversion for
2514 uint/uint. If we have a constant, we avoid doing a typecast to a
2517 * class.cs (Indexer): Implement explicit interface implementation
2520 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
2522 * class.cs: make the default instance constructor public and hidebysig.
2524 2001-01-03 Ravi Pratap <ravi@ximian.com>
2526 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
2527 so we can call it from elsewhere.
2529 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
2530 we emit it internally if the class has a defined indexer; otherwise the user
2531 emits it by decorating the class definition with the DefaultMemberAttribute.
2533 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
2534 attribute is not used on a type which defines an indexer.
2536 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
2537 character when we skip whitespace.
2539 * ../errors/cs0646.cs : Add.
2541 2002-01-03 Miguel de Icaza <miguel@ximian.com>
2543 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
2546 * makefile: Add practical target `mcs3.exe' which builds the third
2547 generation compiler.
2549 * expression.cs (New): Fix structures constructor calling.
2551 * class.cs (Property, Method, Indexer): Emit Final flag on the
2552 method if we are an interface implementation and we are not
2555 * ecore.cs (PropertyExpr): New public field `IsBase', tells
2556 whether this property is referencing a `base' method.
2558 * expression.cs (Invocation.EmitCall): take an extra argument:
2559 is_base, this is used to determine whether the `call' or
2560 `callvirt' opcode should be used.
2563 * delegate.cs: update EmitCall.
2565 * class.cs (Method.Define): Set NewSlot for the cases where we are
2566 not implementing an interface method.
2568 (Property.Define): ditto.
2570 2002-01-02 Miguel de Icaza <miguel@ximian.com>
2572 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
2573 'r'. Allows mcs to parse itself fully.
2575 2002-01-02 Ravi Pratap <ravi@ximian.com>
2577 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
2578 of the number of initializers that require the InitializeArray method.
2580 (CheckIndices): Store the Expression in all cases - not the plain value. Also
2581 update the above field where necessary.
2583 (MakeByteBlob): Update accordingly.
2585 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
2588 (EmitDynamicInitializers): Update in accordance with the new optimization.
2590 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
2591 same OpCode applies.
2593 * cs-parser.jay : Fix some glaring errors I introduced.
2595 2002-01-01 Ravi Pratap <ravi@ximian.com>
2597 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
2598 so that we can check for name clashes there too.
2600 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
2601 for interface indexers.
2603 * interfaces.cs (Define): Emit the default member attribute.
2605 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
2606 variable was being referred to while setting the value ;-)
2608 2002-01-01 Miguel de Icaza <miguel@ximian.com>
2610 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
2611 byte-by-byte information when we know the data is zero.
2613 Make the block always a multiple of 4, because
2614 DefineInitializedData has a bug.
2616 * assign.cs: Fix, we should assign from the temporary, not from
2619 * expression.cs (MakeByteBlob): Fix my incorrect code.
2621 2001-12-31 Miguel de Icaza <miguel@ximian.com>
2623 * typemanager.cs (EnumToUnderlying): This function is used to get
2624 the underlying type from an enumeration, because it does not
2627 * constant.cs: Use the I4_S form for values between -128 and 127.
2629 * statement.cs (Block.LookupLabel): Looks up a label.
2630 (Block): Drop support for labeled blocks.
2632 (LabeledStatement): New kind of statement that represents a label
2635 (Goto): Finally implement this bad boy.
2637 * cs-parser.jay: Update to reflect new mechanism to implement
2640 2001-12-30 Miguel de Icaza <miguel@ximian.com>
2642 * codegen.cs (EmitContext.This): a codegen property that keeps the
2643 a single instance of this instead of creating many different this
2646 * delegate.cs (Delegate.DoResolve): Update to use the property;
2648 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
2650 * expression.cs (BaseAccess.DoResolve): Ditto.
2652 2001-12-29 Ravi Pratap <ravi@ximian.com>
2654 * typemanager.cs (methodimpl_attr_type): Add to hold the type
2655 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
2657 (InitCoreTypes): Update accordingly.
2659 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
2660 so we can quickly store the state.
2662 (ApplyAttributes): Set the correct implementation flags
2663 for InternalCall methods.
2665 2001-12-29 Miguel de Icaza <miguel@ximian.com>
2667 * expression.cs (EmitCall): if a method is not virtual, then do
2668 not use callvirt on it.
2670 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
2671 user defined stuff) requires the use of stobj, which takes an
2672 address on the stack instead of an array and an index. So emit
2673 the Ldelema operation for it.
2675 (EmitStoreOpcode): Use stobj for valuetypes.
2677 (UnaryMutator.EmitCode): Use the right 1 value depending on
2678 whether we are dealing with int64/uint64, float or doubles.
2680 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
2681 constructors that I implemented last night.
2683 (Constructor.IsDefault): Fix to work properly for static
2686 * cs-parser.jay (CheckDef): report method signature errors.
2687 Update error number 103 to be 132.
2689 * decl.cs: New AdditionResult enumeration value: MethodExists.
2690 Although we do this check for methods later on in the semantic
2691 analysis, catching repeated default constructors is so easy that
2692 we catch these here.
2694 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
2697 (ParameterReference.EmitAssign, Emit): handle
2700 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
2701 (ArrayAccess.EmitStoreOpcode): ditto.
2703 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
2705 * expression.cs (MakeByteBlob): Complete all the missing types
2706 (uint, short, ushort, byte, sbyte)
2708 * class.cs: Only init instance field initializers on instance
2711 Rename `constructors' to instance_constructors.
2713 (TypeContainer.AddConstructor): Only add constructors to the list
2714 if it is not static.
2716 Make sure that we handle default_static_constructor independently
2717 everywhere where we handle instance_constructors
2719 2001-12-28 Miguel de Icaza <miguel@ximian.com>
2721 * class.cs: Do not lookup or create a base initializer for a
2724 (ConstructorInitializer.Resolve): use the proper type to lookup
2727 * cs-parser.jay: Report error 1585 (modifiers between type and name).
2729 * enum.cs, interface.cs: Remove CloseType, this is taken care by
2732 * decl.cs: CloseType is now an virtual method, the default
2733 implementation just closes this type.
2735 2001-12-28 Ravi Pratap <ravi@ximian.com>
2737 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
2738 to PreserveSig by default. Also emit HideBySig on such methods.
2740 Basically, set the defaults to standard values.
2742 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
2743 argument, if candidate is better, it can't be worse than the best !
2745 (Invocation): Re-write bits to differentiate between methods being
2746 applicable in their expanded form and their normal form - for params
2749 Get rid of use_standard everywhere as only standard conversions are allowed
2750 in overload resolution.
2752 More spec conformance.
2754 2001-12-27 Miguel de Icaza <miguel@ximian.com>
2756 * driver.cs: Add --timestamp, to see where the compiler spends
2759 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
2760 `this' in static code.
2762 (SimpleName.DoResolve): Implement in terms of a helper function
2763 that allows static-references to be passed upstream to
2766 (Expression.ResolveWithSimpleName): Resolve specially simple
2767 names when called by MemberAccess to implement the special
2770 (Expression.ImplicitReferenceConversion): Handle conversions from
2771 Null to reference types before others, as Null's type is
2774 * expression.cs (Invocation.EmitCall): Handle the special case of
2775 calling methods declared on a reference type from a ValueType
2776 (Base classes System.Object and System.Enum)
2778 (MemberAccess.Resolve): Only perform lookups on Enumerations if
2779 the left hand side is a TypeExpr, not on every enumeration.
2781 (Binary.Resolve): If types are reference types, then do a cast to
2782 object on operators != and == of both arguments.
2784 * typemanager.cs (FindMembers): Extract instance and static
2785 members if requested.
2787 * interface.cs (PopulateProperty): Use void_type instead of null
2788 as the return type for the setter method.
2790 (PopulateIndexer): ditto.
2792 2001-12-27 Ravi Pratap <ravi@ximian.com>
2794 * support.cs (ReflectionParameters): Fix minor bug where we
2795 were examining the wrong parameter for the ParamArray attribute.
2797 Cope with requests for the type of the parameter at position
2798 greater than the params parameter's. We now return the element
2799 type of the params array as that makes more sense.
2801 * expression.cs (Invocation.IsParamsMethodApplicable): Update
2802 accordingly as we no longer have to extract the element type
2805 (Invocation.OverloadResolve): Update.
2807 2001-12-27 Miguel de Icaza <miguel@ximian.com>
2809 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
2810 against IEnumerator, test whether the return value is a descendant
2811 of the IEnumerator interface.
2813 * class.cs (Indexer.Define): Use an auxiliary method to implement
2814 the other bits of the method definition. Begin support for
2815 explicit interface implementation.
2817 (Property.DefineMethod): Use TypeManager.void_type instead of null
2818 for an empty return value.
2820 2001-12-26 Miguel de Icaza <miguel@ximian.com>
2822 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
2823 dealing with a FieldExpr which is composed of a FieldBuilder, in
2824 the code path we did extract the constant, but we should have
2825 obtained the underlying value to be able to cast it (otherwise we
2826 end up in an infinite loop, this is what Ravi was running into).
2828 (ArrayCreation.UpdateIndices): Arrays might be empty.
2830 (MemberAccess.ResolveMemberAccess): Add support for section
2831 14.5.4.1 that deals with the special case of E.I when E is a type
2832 and something else, that I can be a reference to a static member.
2834 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
2835 handle a particular array type to create byte blobs, it is just
2836 something we dont generate byteblobs for.
2838 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
2841 * location.cs (Push): remove the key from the hashtable that we
2842 are about to add. This happens for empty files.
2844 * driver.cs: Dispose files after we have parsed them.
2846 (tokenize): new function that only runs the tokenizer on its
2847 input, for speed testing.
2849 2001-12-26 Ravi Pratap <ravi@ximian.com>
2851 * class.cs (Event.Define): Define the private field only if there
2852 are no accessors defined.
2854 * expression.cs (ResolveMemberAccess): If there is no associated
2855 field with the event, that means we have an event defined with its
2856 own accessors and we should flag error cs0070 since transforming
2857 ourselves into a field is not valid in that case.
2859 * ecore.cs (SimpleName.DoResolve): Same as above.
2861 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
2862 and charset to sane values.
2864 2001-12-25 Ravi Pratap <ravi@ximian.com>
2866 * assign.cs (DoResolve): Perform check on events only if they
2867 are being accessed outside the declaring type.
2869 * cs-parser.jay (event_declarations): Update rules to correctly
2870 set the type of the implicit parameter etc.
2872 (add_accessor, remove_accessor): Set current local parameters.
2874 * expression.cs (Binary): For delegate addition and subtraction,
2875 cast the return value from the method into the appropriate delegate
2878 2001-12-24 Ravi Pratap <ravi@ximian.com>
2880 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
2881 of these as the workaround is unnecessary.
2883 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
2884 delegate data - none of that is needed at all.
2886 Re-write bits to extract the instance expression and the delegate method
2889 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
2892 * attribute.cs (ApplyAttributes): New method to take care of common tasks
2893 of attaching attributes instead of duplicating code everywhere.
2895 * everywhere : Update code to do attribute emission using the above method.
2897 2001-12-23 Miguel de Icaza <miguel@ximian.com>
2899 * expression.cs (IsParamsMethodApplicable): if there are not
2900 parameters, return immediately.
2902 * ecore.cs: The 0 literal can be implicity converted to an enum
2905 (SimpleName.DoResolve): First lookup the type, then lookup the
2908 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
2909 want to get its address. If the InstanceExpression is not
2910 addressable, store the result in a temporary variable, then get
2913 * codegen.cs: Only display 219 errors on warning level or above.
2915 * expression.cs (ArrayAccess): Make it implement the
2916 IMemoryLocation interface.
2918 (Binary.DoResolve): handle the operator == (object a, object b)
2919 and operator != (object a, object b) without incurring into a
2920 BoxedCast (because 5 != o should never be performed).
2922 Handle binary enumerator operators.
2924 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
2925 value type, otherwise use Ldelem_ref.
2927 Use precomputed names;
2929 (AddressOf): Implement address of
2931 * cs-parser.jay (labeled_statement): Fix recursive block
2932 addition by reworking the production.
2934 * expression.cs (New.DoEmit): New has a special case:
2936 If we are dealing with a ValueType, we have a few
2937 situations to deal with:
2939 * The target of New is a ValueType variable, that is
2940 easy, we just pass this as the variable reference
2942 * The target of New is being passed as an argument,
2943 to a boxing operation or a function that takes a
2946 In this case, we need to create a temporary variable
2947 that is the argument of New.
2950 2001-12-23 Ravi Pratap <ravi@ximian.com>
2952 * rootcontext.cs (LookupType): Check that current_type is not null before
2953 going about looking at nested types.
2955 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
2956 not implement the IAssignMethod interface any more.
2958 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
2959 where we tranform them into FieldExprs if they are being resolved from within
2962 * ecore.cs (SimpleName.DoResolve): Do the same here.
2964 * assign.cs (DoResolve, Emit): Clean up code considerably.
2966 * ../errors/bug10.cs : Add.
2968 * ../errors/cs0070.cs : Add.
2970 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
2972 * assign.cs : Get rid of EventIsLocal everywhere.
2974 2001-12-23 Miguel de Icaza <miguel@ximian.com>
2976 * ecore.cs (ConvertIntLiteral): finished the implementation.
2978 * statement.cs (SwitchLabel): Convert the value we are using as a
2979 key before looking up the table.
2981 2001-12-22 Miguel de Icaza <miguel@ximian.com>
2983 * codegen.cs (EmitTopBlock): Require a Location argument now.
2985 * cs-parser.jay (constructor_declarator): We need to setup
2986 current_local_parameters before we parse the
2987 opt_constructor_initializer, to allow the variables to be bound
2988 to the constructor arguments.
2990 * rootcontext.cs (LookupType): First lookup nested classes in our
2991 class and our parents before we go looking outside our class.
2993 * expression.cs (ConstantFold): Extract/debox the values at the
2996 * rootcontext.cs (EmitCode): Resolve the constants first before we
2997 resolve the types. This is not really needed, but it helps debugging.
2999 * statement.cs: report location.
3001 * cs-parser.jay: pass location to throw statement.
3003 * driver.cs: Small bug fix.
3005 * report.cs: Updated format to be 4-zero filled digits.
3007 2001-12-22 Ravi Pratap <ravi@ximian.com>
3009 * expression.cs (CheckIndices): Fix minor bug where the wrong
3010 variable was being referred to ;-)
3012 (DoEmit): Do not call EmitStaticInitializers when the
3013 underlying type is System.Object.
3015 2001-12-21 Ravi Pratap <ravi@ximian.com>
3017 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
3018 and do the usual workaround for SRE.
3020 * class.cs (MyEventBuilder.EventType): New member to get at the type
3021 of the event, quickly.
3023 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
3025 * assign.cs (Assign.DoResolve): Handle the case when the target
3026 is an EventExpr and perform the necessary checks.
3028 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
3031 (SimpleName.MemberStaticCheck): Include check for EventExpr.
3033 (EventExpr): Set the type in the constructor itself since we
3034 are meant to be born fully resolved.
3036 (EventExpr.Define): Revert code I wrote earlier.
3038 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
3039 instance expression is null. The instance expression is a This in that case
3040 or a null, depending on whether it is a static method or not.
3042 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
3043 refers to more than one method.
3045 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
3046 and accordingly flag errors.
3048 2001-12-21 Miguel de Icaza <miguel@ximian.com>
3050 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
3052 2001-12-22 Miguel de Icaza <miguel@ximian.com>
3054 * location.cs (ToString): Provide useful rutine.
3056 2001-12-21 Miguel de Icaza <miguel@ximian.com>
3058 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
3059 objects, return the actual integral boxed.
3061 * statement.cs (SwitchLabel): define an ILLabel for each
3064 (Switch.CheckSwitch): If the value is a Literal, extract
3065 the underlying literal.
3067 Also in the unused hashtable we had, add the SwitchLabel so we can
3068 quickly look this value up.
3070 * constant.cs: Implement a bunch of new constants. Rewrite
3071 Literal based on this. Made changes everywhere to adapt to this.
3073 * expression.cs (Expression.MakeByteBlob): Optimize routine by
3074 dereferencing array only once, and also copes with enumrations.
3076 bytes are two bytes wide, not one.
3078 (Cast): Perform constant conversions.
3080 * ecore.cs (TryImplicitIntConversion): Return literals instead of
3081 wrappers to the literals here.
3083 * expression.cs (DoNumericPromotions): long literals can converted
3084 to ulong implicity (this is taken care of elsewhere, but I was
3087 * ecore.cs (Expression.Literalize): Make the return type Literal,
3088 to improve type checking.
3090 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
3092 2001-12-20 Miguel de Icaza <miguel@ximian.com>
3094 * literal.cs: Revert code from ravi that checked the bounds. The
3095 bounds are sane by the definition of the type itself.
3097 * typemanager.cs: Fix implementation of ImplementsInterface. We
3098 need to actually look up in our parent hierarchy for interfaces
3101 * const.cs: Use the underlying type for enumerations
3103 * delegate.cs: Compute the basename for the delegate creation,
3104 that should fix the delegate test case, and restore the correct
3105 Type Lookup semantics in rootcontext
3107 * rootcontext.cs: Revert Ravi's last patch. The correct way of
3108 referencing a nested type with the Reflection API is using the "+"
3111 * cs-parser.jay: Do not require EOF token at the end.
3113 2001-12-20 Ravi Pratap <ravi@ximian.com>
3115 * rootcontext.cs (LookupType): Concatenate type names with
3116 a '.' instead of a '+' The test suite passes again.
3118 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
3119 field of the enumeration.
3121 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
3122 the case when the member is an EventExpr.
3124 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
3125 static has an associated instance expression.
3127 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
3129 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
3131 * class.cs (Event.Define): Register event and perform appropriate checks
3134 We define the Add and Remove methods even if the use provides none because
3135 in that case, we provide default implementations ourselves.
3137 Define a private field of the type of the event. This is done by the CSC compiler
3138 and we should be doing it too ;-)
3140 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
3141 More methods we use in code we generate.
3143 (multicast_delegate_type, delegate_type): Two separate types since the distinction
3146 (InitCoreTypes): Update accordingly for the above.
3148 * class.cs (Event.Emit): Generate code for default accessors that we provide
3150 (EmitDefaultMethod): Do the job in the above.
3152 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
3155 2001-12-20 Miguel de Icaza <miguel@ximian.com>
3157 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
3158 builders even if we were missing one.
3160 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
3161 pass the Basename as our class name instead of the Name. The
3162 basename will be correctly composed for us.
3164 * parameter.cs (Paramters): Now takes a Location argument.
3166 * decl.cs (DeclSpace.LookupType): Removed convenience function and
3167 make all the code call directly LookupType in RootContext and take
3168 this chance to pass the Location information everywhere.
3170 * Everywhere: pass Location information.
3172 2001-12-19 Miguel de Icaza <miguel@ximian.com>
3174 * class.cs (Constructor.Define): Updated way of detecting the
3175 length of the parameters.
3177 (TypeContainer.DefineType): Use basename as the type name for
3180 (TypeContainer.Define): Do not recursively define types here, as
3181 definition is taken care in order by the RootContext.
3183 * tree.cs: Keep track of namespaces in a per-file basis.
3185 * parameter.cs (Parameter.ComputeSignature): Update to use
3188 (Parameters.GetSignature): ditto.
3190 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
3191 instead of a TypeContainer.
3193 (Interface.SemanticAnalysis): Use `this' instead of our parent to
3194 resolve names. Because we need to be resolve in our context, not
3197 * driver.cs: Implement response files.
3199 * class.cs (TypeContainer.DefineType): If we are defined, do not
3202 (Event.Emit): Emit the code for add/remove handlers.
3203 (Event.Define): Save the MethodBuilders for add/remove.
3205 * typemanager.cs: Use pair here too.
3207 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
3208 DictionaryEntry requires the first argument to be non-null.
3210 (enum_declaration): Compute full name for registering the
3213 (delegate_declaration): Instead of using
3214 formal_parameter_list, use opt_formal_parameter_list as the list
3217 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
3218 (EventParsing): New property that controls whether `add' and
3219 `remove' are returned as tokens or identifiers (for events);
3221 2001-12-19 Ravi Pratap <ravi@ximian.com>
3223 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
3224 use MyEventBuilder only and let it wrap the real builder for us.
3226 (MyEventBuilder): Revamp constructor etc.
3228 Implement all operations that we perform on EventBuilder in precisely the same
3231 (FindMembers): Update to use the EventBuilder member.
3233 (Event.Emit): Update accordingly.
3235 2001-12-18 Ravi Pratap <ravi@ximian.com>
3237 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
3238 by calling the appropriate methods.
3240 (GetCustomAttributes): Make stubs as they cannot possibly do anything
3243 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
3245 2001-12-17 Ravi Pratap <ravi@ximian.com>
3247 * delegate.cs (Delegate.Populate): Check that the return type
3248 and various parameters types are indeed accessible.
3250 * class.cs (Constructor.Define): Same here.
3252 (Field.Define): Ditto.
3254 (Event.Define): Ditto.
3256 (Operator.Define): Check that the underlying Method defined itself
3257 correctly - so it's MethodBuilder should not be null.
3259 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
3260 expression happens to be null.
3262 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
3263 members but as of now we don't seem to be able to do anything really useful with it.
3265 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
3266 not the EventBuilder.
3268 2001-12-18 Miguel de Icaza <miguel@ximian.com>
3270 * cs-tokenizer.cs: Add support for defines.
3271 Add support for #if, #elif, #else, #endif
3273 (eval_var): evaluates a variable.
3274 (eval): stubbed for evaluating functions.
3276 * cs-parser.jay: Pass the defines information
3278 * driver.cs: Add --define command line option.
3280 * decl.cs: Move MemberCore here.
3282 Make it the base class for DeclSpace. This allows us to catch and
3283 report 108 and 109 for everything now.
3285 * class.cs (TypeContainer.Define): Extract all the members
3286 before populating and emit the warning 108 (new keyword required
3287 to override) instead of having each member implement this.
3289 (MemberCore.Define): New abstract method, we will be using this in
3290 the warning reporting engine in Populate.
3292 (Operator.Define): Adjust to new MemberCore protocol.
3294 * const.cs (Const): This does not derive from Expression, it is a
3295 temporary object we use to create fields, it is a MemberCore.
3297 * class.cs (Method.Define): Allow the entry point to be in a
3300 * driver.cs: Rewrite the argument handler to clean it up a bit.
3302 * rootcontext.cs: Made it just an auxiliary namespace feature by
3303 making everything static.
3305 * driver.cs: Adapt code to use RootContext type name instead of
3308 * delegate.cs: Remove RootContext argument.
3310 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
3313 * class.cs (Event.Define): The lookup can fail.
3315 * cs-tokenizer.cs: Begin implementation of pre-procesor.
3317 * expression.cs: Resolve the this instance before invoking the code.
3319 2001-12-17 Miguel de Icaza <miguel@ximian.com>
3321 * cs-parser.jay: Add a production in element_access that allows
3322 the thing to become a "type" reference. This way we can parse
3323 things like "(string [])" as a type.
3325 Note that this still does not handle the more complex rules of
3329 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
3331 * ecore.cs: (CopyNewMethods): new utility function used to
3332 assemble the list of methods from running FindMembers.
3334 (MemberLookup): Rework FindMembers so that
3336 2001-12-16 Miguel de Icaza <miguel@ximian.com>
3338 * class.cs (TypeContainer): Remove Delegates who fail to be
3341 * delegate.cs (Populate): Verify that we dont get null return
3342 values. TODO: Check for AsAccessible.
3344 * cs-parser.jay: Use basename to emit error 574 (destructor should
3345 have the same name as container class), not the full name.
3347 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
3348 possible representation.
3350 Also implements integer type suffixes U and L.
3352 2001-12-15 Miguel de Icaza <miguel@ximian.com>
3354 * expression.cs (ArrayCreation.DoResolve): We need to do the
3355 argument resolution *always*.
3357 * decl.cs: Make this hold the namespace. Hold the root context as
3359 (LookupType): Move here.
3361 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
3363 * location.cs (Row, Name): Fixed the code, it was always returning
3364 references to the first file.
3366 * interface.cs: Register properties defined through interfaces.
3368 * driver.cs: Add support for globbing on the command line
3370 * class.cs (Field): Make it derive from MemberCore as well.
3373 2001-12-15 Ravi Pratap <ravi@ximian.com>
3375 * class.cs (Event::Define): Check that the type of the event is a delegate
3376 type else flag error #66.
3378 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
3381 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
3382 values of EntryPoint, CharSet etc etc.
3384 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
3386 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
3387 be null and we should ignore this. I am not sure if this is really clean. Apparently,
3388 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
3389 which needs this to do its work.
3391 * ../errors/cs0066.cs : Add.
3393 2001-12-14 Miguel de Icaza <miguel@ximian.com>
3395 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
3398 * class.cs: (MethodSignature.MethodSignature): Removed hack that
3399 clears out the parameters field.
3400 (MemberSignatureCompare): Cleanup
3402 (MemberCore): New base class used to share code between MethodCore
3405 (RegisterRequiredImplementations) BindingFlags.Public requires
3406 either BindingFlags.Instace or Static. Use instance here.
3408 (Property): Refactored code to cope better with the full spec.
3410 * parameter.cs (GetParameterInfo): Return an empty array instead
3413 * class.cs (Property): Abstract or extern properties have no bodies.
3415 * parameter.cs (GetParameterInfo): return a zero-sized array.
3417 * class.cs (TypeContainer.MethodModifiersValid): Move all the
3418 method modifier validation to the typecontainer so we can reuse
3421 (MethodCore.ParameterTypes): return an empty sized array of types.
3423 (Property.Define): Test property modifier validity.
3425 Add tests for sealed/override too.
3427 (Method.Emit): abstract or extern methods have no bodies.
3429 2001-12-14 Ravi Pratap <ravi@ximian.com>
3431 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
3434 (Method::Define, ::Emit): Modify accordingly.
3436 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
3438 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
3440 * makefile: Pass in /unsafe.

3444 * class.cs (MakeKey): Kill routine.
3446 * class.cs (TypeContainer.Define): Correctly define explicit
3447 method implementations (they require the full interface name plus
3450 * typemanager.cs: Deply the PtrHashtable here and stop using the
3451 lame keys. Things work so much better.
3453 This of course broke everyone who depended on `RegisterMethod' to
3454 do the `test for existance' test. This has to be done elsewhere.
3456 * support.cs (PtrHashtable): A hashtable that avoid comparing with
3457 the object stupid Equals method (because, that like fails all over
3458 the place). We still do not use it.
3460 * class.cs (TypeContainer.SetRequiredInterface,
3461 TypeContainer.RequireMethods): Killed these two routines and moved
3462 all the functionality to RegisterRequiredImplementations.
3464 (TypeContainer.RegisterRequiredImplementations): This routine now
3465 registers all the implementations required in an array for the
3466 interfaces and abstract methods. We use an array of structures
3467 which can be computed ahead of time to reduce memory usage and we
3468 also assume that lookups are cheap as most classes will not
3469 implement too many interfaces.
3471 We also avoid creating too many MethodSignatures.
3473 (TypeContainer.IsInterfaceMethod): Update and optionally does not
3474 clear the "pending" bit if we find that there are problems with
3477 (TypeContainer.VerifyPendingMethods): Update to report errors of
3478 methods that look like implementations but are not.
3480 (TypeContainer.Define): Add support for explicit interface method
3483 2001-12-12 Miguel de Icaza <miguel@ximian.com>
3485 * typemanager.cs: Keep track of the parameters here instead of
3486 being a feature of the TypeContainer.
3488 * class.cs: Drop the registration of parameters here, as
3489 InterfaceMethods are also interface declarations.
3491 * delegate.cs: Register methods with the TypeManager not only with
3492 the TypeContainer. This code was buggy.
3494 * interface.cs: Full registation here.
3496 2001-12-11 Miguel de Icaza <miguel@ximian.com>
3498 * expression.cs: Remove reducer for binary expressions, it can not
3501 * const.cs: Put here the code that used to go into constant.cs
3503 * constant.cs: Put here the code for constants, this is a new base
3506 * literal.cs: Make Literal derive from Constant.
3508 2001-12-09 Miguel de Icaza <miguel@ximian.com>
3510 * statement.cs (Return.Emit): Report error 157 if the user
3511 attempts to return from a finally block.
3513 (Return.Emit): Instead of emitting a return, jump to the end of
3516 * codegen.cs (EmitContext): ReturnValue, ReturnLabel: new
3517 LocalBuilder to store the result of the function. ReturnLabel is
3518 the target where we jump.
3521 2001-12-09 Radek Doulik <rodo@ximian.com>
3523 * cs-parser.jay: remember alias in current namespace
3525 * ecore.cs (SimpleName::DoResolve): use aliases for types or
3528 * class.cs (LookupAlias): lookup alias in my_namespace
3530 * namespace.cs (UsingAlias): add alias, namespace_or_type pair to
3532 (LookupAlias): lookup alias in this and if needed in parent
3535 2001-12-08 Miguel de Icaza <miguel@ximian.com>
3539 * rootcontext.cs: (ModuleBuilder) Made static, first step into
3540 making things static. I need this to avoid passing the
3541 TypeContainer when calling ParameterType.
3543 * support.cs (InternalParameters.ParameterType): Remove ugly hack
3544 that did string manipulation to compute the type and then call
3545 GetType. Use Parameter.ParameterType instead.
3547 * cs-tokenizer.cs: Consume the suffix for floating values.
3549 * expression.cs (ParameterReference): figure out whether this is a
3550 reference parameter or not. Kill an extra variable by computing
3551 the arg_idx during emission.
3553 * parameter.cs (Parameters.GetParameterInfo): New overloaded
3554 function that returns whether a parameter is an out/ref value or not.
3556 (Parameter.ParameterType): The type of the parameter (base,
3557 without ref/out applied).
3559 (Parameter.Resolve): Perform resolution here.
3560 (Parameter.ExternalType): The full type (with ref/out applied).
3562 * statement.cs (Using.Emit, Using.EmitExpression): Implement
3563 support for expressions on the using statement.
3565 2001-12-07 Miguel de Icaza <miguel@ximian.com>
3567 * statement.cs (Using.EmitLocalVariableDecls): Split the
3568 localvariable handling of the using statement.
3570 (Block.EmitMeta): Keep track of variable count across blocks. We
3571 were reusing slots on separate branches of blocks.
3573 (Try.Emit): Emit the general code block, we were not emitting it.
3575 Check the type of the declaration to be an IDisposable or
3576 something that can be implicity converted to it.
3578 Emit conversions if required.
3580 * ecore.cs (EmptyExpression): New utility class.
3581 (Expression.ImplicitConversionExists): New utility function.
3583 2001-12-06 Miguel de Icaza <miguel@ximian.com>
3585 * statement.cs (Using): Implement.
3587 * expression.cs (LocalVariableReference): Support read only variables.
3589 * statement.cs: Remove the explicit emit for the Leave opcode.
3590 (VariableInfo): Add a readonly field.
3592 2001-12-05 Miguel de Icaza <miguel@ximian.com>
3594 * ecore.cs (ConvCast): new class used to encapsulate the various
3595 explicit integer conversions that works in both checked and
3598 (Expression.ConvertNumericExplicit): Use new ConvCast class to
3599 properly generate the overflow opcodes.
3601 2001-12-04 Miguel de Icaza <miguel@ximian.com>
3603 * statement.cs: The correct type for the EmptyExpression is the
3604 element_type, not the variable type. Ravi pointed this out.
3606 2001-12-04 Ravi Pratap <ravi@ximian.com>
3608 * class.cs (Method::Define): Handle PInvoke methods specially
3609 by using DefinePInvokeMethod instead of the usual one.
3611 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
3612 above to do the task of extracting information and defining the method.
3614 2001-12-04 Ravi Pratap <ravi@ximian.com>
3616 * expression.cs (ArrayCreation::EmitStaticInitializers): Get rid
3617 of the condition for string type.

3638 * statement.cs (GotoDefault), cs-parser.jay: Implement `goto
3641 (Foreach.Emit): Foreach on arrays was not setting
3642 up the loop variables (for break/continue).
3644 (GotoCase): Semi-implented.
3646 2001-12-03 Ravi Pratap <ravi@ximian.com>

3696 As that share bits of the implementation. Is returns a boolean,
3697 while As returns the Type that is being probed.
3699 2001-12-01 Ravi Pratap <ravi@ximian.com>
3701 * enum.cs (LookupEnumValue): Re-write various bits, return an object value
3702 instead of a Literal - much easier.
3704 (EnumInTransit): Remove - utterly useless :-)
3706 (Populate): Re-write bits - remove duplicate code etc. The code is much neater now.
3708 * expression.cs (MemberLookup): Cope with user-defined enums when they are in transit.

3852 (MakeByteBlob): Handle types more correctly.
3854 * expression.cs (ArrayCreation:Emit): Write preliminary code to do
3855 initialization from expressions but it is incomplete because I am a complete
3858 2001-11-22 Miguel de Icaza <miguel@ximian.com>
3860 * statement.cs (If.Emit): Fix a bug that generated incorrect code
3861 on If. Basically, we have to return `true' (ie, we do return to
3862 our caller) only if both branches of the if return.
3864 * expression.cs (Binary.Emit): LogicalOr and LogicalAnd are
3865 short-circuit operators, handle them as short circuit operators.

3868 (Cast.Cast): Take an expression as the target type.
3870 * cs-parser.jay (cast_expression): Remove old hack that only

3875 Use the grammar productions from Rhys to handle casts (this is
3876 not complete like Rhys syntax yet, we fail to handle that corner
3877 case that C# has regarding (-x), but we will get there.

3924 (Expression.ImplicitNumericConversion): Oops, forgot to test for

3928 2001-11-21 Miguel de Icaza <miguel@ximian.com>
3930 * cs-parser.jay (for_statement): Reworked the way For works: now
3931 we declare manually any variables that are introduced in
3932 for_initializer to solve the problem of having out-of-band code
3933 emition (that is what got for broken).
3935 (declaration_statement): Perform the actual variable declaration
3936 that used to be done in local_variable_declaration here.
3938 (local_variable_declaration): Do not declare anything, just pass
3939 the information on a DictionaryEntry
3941 2001-11-20 Ravi Pratap <ravi@ximian.com>
3943 * expression.cs (ArrayCreation::CheckIndices): The story continues :-) Complete

4006 we can use this elsewhere.
4008 * statement.cs: Finish implementation of foreach for single
4011 * cs-parser.jay: Use an out-of-band stack to pass information
4012 around, I wonder why I need this.
4014 foreach_block: Make the new foreach_block the current_block.
4016 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
4017 function used to return a static Parameters structure. Used for
4018 empty parameters, as those are created very frequently.
4020 * cs-parser.jay, class.cs: Use GetEmptyReadOnlyParameters
4022 2001-11-15 Ravi Pratap <ravi@ximian.com>
4024 * interface.cs : Default modifier is private, not public. The
4025 make verify test passes again.
4027 2001-11-15 Ravi Pratap <ravi@ximian.com>
4029 * support.cs (ReflectionParameters): Fix logic to determine

4063 2001-11-09 Miguel de Icaza <miguel@ximian.com>

4073 * support.cs (ReflectionParameters.ParameterModifier): Report
4074 whether the argument is a PARAMS argument or not.
4076 * class.cs: Set the attribute `ParamArrayAttribute' on the
4079 * typemanager.cs: Define param_array_type (ParamArrayAttribute)
4080 and cons_param_array_attribute (ConstructorInfo for
4081 ParamArrayAttribute).,
4083 * codegen.cs: Emit the return using the `Return' statement, that
4084 way we can report the error correctly for missing return values.
4086 * class.cs (Method.Emit): Clean up.
4088 * expression.cs (Argument.Resolve): Take another argument: the
4089 location where this argument is used. Notice that this is not
4090 part of the "Argument" class as to reduce the size of the
4091 structure (we know the approximate location anyways).
4093 Test if the argument is a variable-reference, if not, then
4094 complain with a 206.
4096 (Argument.Emit): Emit addresses of variables.

4127 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
4128 enumerations that are used in heavily used structures derive from
4129 byte in a laughable and pathetic attempt to reduce memory usage.
4130 This is the kind of pre-optimzations that you should not do at
4131 home without adult supervision.
4133 * expression.cs (UnaryMutator): New class, used to handle ++ and
4134 -- separatedly from the other unary operators. Cleans up the
4135 code, and kills the ExpressionStatement dependency in Unary.
4137 (Unary): Removed `method' and `Arguments' from this class, making
4138 it smaller, and moving it all to SimpleCall, so I can reuse this
4139 code in other locations and avoid creating a lot of transient data
4140 strucutres when not required.
4142 * cs-parser.jay: Adjust for new changes.
4144 2001-11-11 Miguel de Icaza <miguel@ximian.com>

4207 * class.cs, rootcontext.cs : Update accordingly.
4209 * typemanager.cs (RegisterField, GetValue): Workarounds for the fact that

4215 of a fieldinfo using the above, when dealing with a FieldBuilder.

4305 as we had no way of defining nested enums !
4307 * rootcontext.cs : Adjust code accordingly.
4309 * typemanager.cs (AddEnumType): To keep track of enum types separately.
4311 2001-11-07 Ravi Pratap <ravi@ximian.com>

4603 * typemanager.cs (ImplementsInterface): interface might be null;
4604 Deal with this problem;
4606 Also, we do store negative hits on the cache (null values), so use
4607 this instead of calling t.GetInterfaces on the type everytime.

4897 and accordingly handle it.
4899 * delegate.cs (Populate): Take TypeContainer argument.

4906 * expression.cs (ImplicitReferenceConversion): Implement guts of implicit array

4918 name as it is a type declaration.
4920 * delegate.cs (ReturnType, Name): Rename members to these. Make them

4982 methods on value types. We need to pass the address to structure
4983 methods rather than the object itself. (The equivalent code to
4984 emit "this" for structures leaves the entire structure on the
4985 stack instead of a pointer to it).
4987 (ParameterReference::DoResolve): Compute the real index for the
4988 argument based on whether the method takes or not a `this' pointer
4989 (ie, the method is static).
4991 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store

5029 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
5030 to TypeContainer mapping to see if a type is user-defined.
5032 * class.cs (TypeContainer::CloseType): Implement.
5034 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
5035 the default constructor.
5037 (TypeContainer::Populate): Fix minor bug which led to creating default constructors
5040 (Constructor::IsDefault): Fix up logic to determine if it is the default constructor
5042 * interface.cs (CloseType): Create the type here.

5058 * expression.cs (ImplicitReferenceConversion): handle null as well
5059 as a source to convert to any reference type.
5061 * statement.cs (Return): Perform any implicit conversions to
5062 expected return type.
5064 Validate use of return statement.
5066 * codegen.cs (EmitContext): Pass the expected return type here.
5068 * class.cs (Method, Constructor, Property): Pass expected return
5069 type to EmitContext.
5071 2001-10-09 Miguel de Icaza <miguel@ximian.com>

5083 * codegen.cs: EmitContext now contains a flag indicating whether
5084 code is being generated in a static method or not.
5086 * cs-parser.jay: DecomposeQI, new function that replaces the old
5087 QualifiedIdentifier. Now we always decompose the assembled
5088 strings from qualified_identifier productions into a group of

5152 * class.cs: Catch static methods having the flags override,
5153 virtual or abstract.
5155 * expression.cs (UserCast): This user cast was not really doing
5156 what it was supposed to do. Which is to be born in fully resolved
5157 state. Parts of the resolution were being performed at Emit time!
5161 2001-10-05 Miguel de Icaza <miguel@ximian.com>
5163 * expression.cs: Implicity convert the result from UserCast.

5189 UserDefinedConversion.

5228 before defining the methods.

5231 instead of inside a tight loop.
5233 (::RequireMethods): Accept an object as the data to set into the
5234 hashtable so we can report interface vs abstract method mismatch.
5236 2001-10-03 Miguel de Icaza <miguel@ximian.com>
5238 * report.cs: Make all of it static.
5240 * rootcontext.cs: Drop object_type and value_type computations, as
5241 we have those in the TypeManager anyways.
5243 Drop report instance variable too, now it is a global.
5245 * driver.cs: Use try/catch on command line handling.
5247 Add --probe option to debug the error reporting system with a test
5250 * report.cs: Add support for exiting program when a probe

5272 Also fix logic to find members in base types.

5293 in order from base classes to child classes, so that we can in
5294 child classes look up in our parent for method names and
5295 attributes (required for handling abstract, virtual, new, override
5296 constructs: we need to instrospect our base class, and if we dont
5297 populate the classes in order, the introspection might be
5298 incorrect. For example, a method could query its parent before
5299 the parent has any methods and would determine that the parent has
5300 no abstract methods (while it could have had them)).
5302 (RootContext::CreateType): Record the order in which we define the

5323 not marked abstract or extern).
5325 * expression.cs (TypeOf::Emit): Implement.

5329 * class.cs (Property::Emit): Generate code for properties.
5331 2001-10-02 Ravi Pratap <ravi@ximian.com>

5370 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
5372 2001-10-01 Miguel de Icaza <miguel@ximian.com>
5374 * expression.cs (Expression::ExprClassFromMemberInfo,
5375 Expression::Literalize): Create literal expressions from
5376 FieldInfos which are literals.

5394 * parameter.cs: Do not dereference potential null value.

5400 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
5402 * class.cs: Only add constructor to hashtable if it is non-null

5444 (Binary::DoNumericPromotions): In the case where either argument
5445 is ulong (and most signed types combined with ulong cause an
5446 error) perform implicit integer constant conversions as well.

5463 (Binary::ResolveOperator): Do not compute the expensive argumnets
5464 unless we have a union for it.
5466 (Probe::Emit): Is needs to do an isinst and then
5467 compare against null.
5469 (::CanConvert): Added Location argument. If the Location argument
5470 is null (Location.Null), then we do not report errors. This is
5471 used by the `probe' mechanism of the Explicit conversion. We do
5472 not want to generate an error for something that the user
5473 explicitly requested to be casted. But the pipeline for an
5474 explicit cast first tests for potential implicit casts.
5476 So for now, if the Location is null, it means `Probe only' to
5477 avoid adding another argument. Might have to revise this
5480 (ClassCast): New class used to type cast objects into arbitrary
5481 classes (used in Explicit Reference Conversions).
5483 Implement `as' as well.
5485 Reverted all the patches from Ravi below: they were broken:
5487 * The use of `level' as a mechanism to stop recursive
5488 invocations is wrong. That was there just to catch the
5489 bug with a strack trace but not as a way of addressing
5492 To fix the problem we have to *understand* what is going
5493 on and the interactions and come up with a plan, not
5494 just get things going.
5496 * The use of the type conversion cache that I proposed
5497 last night had an open topic: How does this work across
5498 protection domains. A user defined conversion might not
5499 be public in the location where we are applying the
5500 conversion, a different conversion might be selected
5501 (ie, private A->B (better) but public B->A (worse),
5502 inside A, A->B applies, but outside it, B->A will
5505 * On top of that (ie, even if the above is solved),
5506 conversions in a cache need to be abstract. Ie, `To
5507 convert from an Int to a Short use an OpcodeCast', not
5508 `To convert from an Int to a Short use the OpcodeCast on
5509 the variable 5' (which is what this patch was doing).
5511 2001-09-28 Ravi Pratap <ravi@ximian.com>
5513 * expression.cs (Invocation::ConversionExists): Re-write to use
5514 the conversion cache
5516 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
5517 cache all conversions done, not just user-defined ones.
5519 (Invocation::BetterConversion): The real culprit. Use ConversionExists
5520 to determine if a conversion exists instead of acutually trying to
5521 perform the conversion. It's faster too.
5523 (Expression::ConvertExplicit): Modify to use ConversionExists to check
5524 and only then attempt the implicit conversion.
5526 2001-09-28 Ravi Pratap <ravi@ximian.com>
5528 * expression.cs (ConvertImplicit): Use a cache for conversions
5529 already found. Check level of recursion and bail out if necessary.

5544 * codegen.cs: remove unnneded code
5546 * expression.cs: Removed BuiltinTypeAccess class
5548 Fix the order in which implicit conversions are
5551 The previous fixed dropped support for boxed conversions (adding a
5552 test to the test suite now)
5554 (UserImplicitCast::CanConvert): Remove test for source being null,
5555 that code is broken. We should not feed a null to begin with, if
5556 we do, then we should track the bug where the problem originates
5557 and not try to cover it up here.
5559 Return a resolved expression of type UserImplicitCast on success
5560 rather than true/false. Ravi: this is what I was talking about,
5561 the pattern is to use a static method as a "constructor" for
5564 Also, do not create arguments until the very last minute,
5565 otherwise we always create the arguments even for lookups that
5566 will never be performed.
5568 (UserImplicitCast::Resolve): Eliminate, objects of type
5569 UserImplicitCast are born in a fully resolved state.
5571 * typemanager.cs (InitCoreTypes): Init also value_type
5574 * expression.cs (Cast::Resolve): First resolve the child expression.
5576 (LValue): Add new method AddressOf to be used by
5579 Change the argument of Store to take an EmitContext instead of an
5580 ILGenerator, because things like FieldExpr need to be able to call
5581 their children expression to generate the instance code.
5583 (Expression::Error, Expression::Warning): Sugar functions for
5586 (Expression::MemberLookup): Accept a TypeContainer instead of a
5587 Report as the first argument.
5589 (Expression::ResolvePrimary): Killed. I still want to improve
5590 this as currently the code is just not right.
5592 (Expression::ResolveMemberAccess): Simplify, but it is still
5595 (Unary::Resolve): Catch errors in AddressOf operators.
5597 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
5598 index to a byte for the short-version, or the compiler will choose
5599 the wrong Emit call, which generates the wrong data.
5601 (ParameterReference::Emit, ::Store): same.
5603 (FieldExpr::AddressOf): Implement.
5605 * typemanager.cs: TypeManager: made public variable instead of
5608 * driver.cs: document --fatal.
5610 * report.cs (ErrorMessage, WarningMessage): new names for the old
5611 Error and Warning classes.
5613 * cs-parser.jay (member_access): Turn built-in access to types
5614 into a normal simplename

5632 * expression.cs (UserImplicitCast::CanConvert): Static method to do
5633 the work of all the checking.
5634 (ConvertImplicit): Call CanConvert and only then create object if necessary.
5635 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
5637 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
5638 that is the right way.
5640 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
5641 overloading resolution. Use everywhere instead of cutting and pasting code.
5643 (Binary::ResolveOperator): Use MakeUnionSet.
5645 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
5646 we have to convert to bool types. Not complete yet.

5652 * expression.cs (Expression::TryImplicitIntConversion): Attempts
5653 to provide an expression that performsn an implicit constant int
5654 conversion (section 6.1.6).

5656 implicit constant expression conversions.
5658 (Expression::ConvertNumericExplicit): Finished.
5660 (Invocation::Emit): If InstanceExpression is null, then it means
5661 that we perform a call on this.
5663 2001-09-26 Miguel de Icaza <miguel@ximian.com>
5665 * expression.cs (Unary::Emit): Remove some dead code.
5666 (Probe): Implement Resolve and Emit for `is'.
5667 (Expression::ConvertImplicitRequired): Attempt to do constant
5668 expression conversions here. Maybe should be moved to
5669 ConvertImplicit, but I am not sure.
5670 (Expression::ImplicitLongConstantConversionPossible,
5671 Expression::ImplicitIntConstantConversionPossible): New functions
5672 that tell whether is it possible to apply an implicit constant
5673 expression conversion.

5678 * cs-parser.jay: Update operator constants.
5680 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs

5685 * class.cs (Operator): Update the operator names to reflect the
5686 ones that the spec expects (as we are just stringizing the
5689 * expression.cs (Unary::ResolveOperator): Fix bug: Use
5690 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
5691 previous usage did only work for our methods.
5692 (Expression::ConvertImplicit): Handle decimal implicit numeric
5693 conversions as well.
5694 (Expression::InternalTypeConstructor): Used to invoke constructors
5695 on internal types for default promotions.
5697 (Unary::Emit): Implement special handling for the pre/post
5698 increment/decrement for overloaded operators, as they need to have
5699 the same semantics as the other operators.
5701 (Binary::ResolveOperator): ditto.

5719 * assign.cs (Assign): Make it inherit from ExpressionStatement.
5721 * expression.cs (ExpressionStatement): New base class used for
5722 expressions that can appear in statements, so that we can provide
5723 an alternate path to generate expression that do not leave a value
5726 (Expression::Emit, and all the derivatives): We no longer return
5727 whether a value is left on the stack or not. Every expression
5728 after being emitted leaves a single value on the stack.
5730 * codegen.cs (EmitContext::EmitStatementExpression): Use the

5758 * assign.cs: track location.
5759 (Resolve): Use implicit conversions on assignment.

5824 * typemanager.cs: declare and load enum_type, delegate_type and
5827 * expression.cs (Expression::Emit): Now emit returns a value that
5828 tells whether a value is left on the stack or not. This strategy
5829 might be reveted tomorrow with a mechanism that would address
5830 multiple assignments.
5831 (Expression::report118): Utility routine to report mismatches on
5834 (Unary::Report23): Report impossible type/operator combination

5883 functions, throw exceptions so it is obvious that we are facing a
5886 * cs-parser.jay (invocation_expression): Pass Location information.
5888 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
5889 Use a basename for those routines because .NET does not like paths

5909 (IntLiteral): export the `Value' of the intliteral.

5960 the last instruction contains a return opcode to avoid generating
5961 the last `ret' instruction (this generates correct code, and it is
5962 nice to pass the peverify output).
5964 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
5965 initializer for static and instance variables.

6023 (Expression::MemberLookup): Provide a version that allows to
6024 specify the MemberTypes and BindingFlags.

6029 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
6030 Beforefieldinit as it was buggy.
6032 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
6035 * class.cs (Constructor::Emit): Only emit if block is not null.
6036 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
6037 deal with this by semantically definining it as if the user had

6041 constructors as we now "emit" them at a higher level.

6121 of a Constructor and a Method.
6122 (Method, Constructor): Factored pieces into MethodCore.

6125 Load System assembly as well as part of the standard library.
6127 * report.cs: Allow throwing exceptions on errors for debugging.
6129 * modifiers.cs: Do not use `parent', instead use the real type
6130 container to evaluate permission settings.
6132 * class.cs: Put Ravi's patch back in. He is right, and we will
6133 have to cope with the
6135 2001-09-14 Ravi Pratap <ravi@ximian.com>
6137 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

6142 * driver.cs: Added --parse option that only parses its input files
6145 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
6146 incorrect. IsTopLevel is not used to tell whether an object is
6147 root_types or not (that can be achieved by testing this ==
6148 root_types). But to see if this is a top-level *class* (not
6149 necessarly our "toplevel" container).
6151 2001-09-14 Ravi Pratap <ravi@ximian.com>
6153 * enum.cs (Enum::Define): Modify to call the Lookup method on the
6154 parent instead of a direct call to GetType.
6156 2001-09-14 Ravi Pratap <ravi@ximian.com>
6158 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
6159 Modifiers.TypeAttr. This should just be a call to that method.
6161 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
6162 object so that we can determine if we are top-level or not.
6164 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the

6173 to precisely that info.
6175 * modifiers.cs (MethodAttr): Re-write.
6176 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
6178 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
6179 of top-level types as claimed.
6181 2001-09-13 Miguel de Icaza <miguel@ximian.com>
6183 * expression.cs (MemberLookup): Fruitless attempt to lookup
6184 constructors. Maybe I need to emit default constructors? That
6185 might be it (currently .NET emits this for me automatically).
6186 (Invocation::OverloadResolve): Cope with Arguments == null.
6187 (Invocation::EmitArguments): new function, shared by the new

6209 objects that we might have around.
6211 (Populate): Only initialize method_builders_to_methods once.
6213 * expression.cs (PropertyExpr): Initialize type from the
6216 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

6220 * expression.cs: Set the type for the int32/int32 argument case.
6221 (Binary::ResolveOperator): Set the return type to boolean for
6222 comparission operators
6224 * typemanager.cs: Remove debugging print code.
6226 (Invocation::Resolve): resolve type.
6228 * class.cs: Allocate a MemberInfo of the correct size, as the code
6229 elsewhere depends on the test to reflect the correct contents.
6231 (Method::) Keep track of parameters, due to System.Reflection holes
6233 (TypeContainer::Populate): Keep track of MethodBuilders to Method
6236 (TypeContainer::FindMembers): Use ArrayList and then copy an array
6237 of the exact size and return that.
6239 (Class::LookupMethodByBuilder): New function that maps
6240 MethodBuilders to its methods. Required to locate the information
6241 on methods because System.Reflection bit us again.
6243 * support.cs: New file, contains an interface ParameterData and
6244 two implementations: ReflectionParameters and InternalParameters
6245 used to access Parameter information. We will need to grow this
6248 * expression.cs (Invocation::GetParameterData): implement a cache
6249 and a wrapper around the ParameterData creation for methods.
6250 (Invocation::OverloadResolve): Use new code.
6252 2001-09-13 Ravi Pratap <ravi@ximian.com>

6274 (ParameterReference::Emit): Implement.
6276 * cs-parser.jay: Fix bug introduced by Ravi, variable initializers

6306 2001-09-12 Ravi Pratap <ravi@ximian.com>
6308 * class.cs (TypeContainer::FindMembers): Method which does exactly
6309 what Type.FindMembers does, only we don't have to use reflection. No
6312 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
6313 typecontainer objects as we need to get at them.
6314 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

6342 (Property::Define): Ditto.

6363 (Populate): Iterate thru the indexers we have and define them too.

6408 on the name without any prefixes of namespace names etc. This is because we
6409 already might have something already fully qualified like
6410 'System.Console.WriteLine'

6561 will is used during the tree rewriting as we resolve them during
6564 (Expression::MemberLookup): Implements the MemberLookup (7.3) from

6688 * class.cs (Property): Revamp to use the convention of making fields readonly.

6737 and re-write the code in the actions to extract the specific and
6738 general catch clauses by being a little smart ;-)
6740 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
6741 Hooray, try and catch statements parse fine !
6743 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
6745 * statement.cs (Block::GetVariableType): Fix logic to extract the type
6746 string from the hashtable of variables.
6748 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did
6749 I end up making that mistake ;-)
6750 (catch_clauses): Fixed gross error which made Key and Value of the
6751 DictionaryEntry the same : $1 !!
6753 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
6755 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
6757 * cs-parser.jay (event_declaration): Correct to remove the semicolon
6758 when the add and remove accessors are specified.
6760 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
6762 * cs-parser.jay (IndexerDeclaration): New helper class to hold
6763 information about indexer_declarator.
6764 (indexer_declarator): Implement actions.
6765 (parsing_indexer): New local boolean used to keep track of whether
6766 we are parsing indexers or properties. This is necessary because
6767 implicit_parameters come into picture even for the get accessor in the
6769 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
6771 * class.cs (Indexer): New class for indexer declarations.
6772 (TypeContainer::AddIndexer): New method to add an indexer to a type.
6773 (TypeContainer::indexers): New member to hold list of indexers for the
6776 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
6778 * cs-parser.jay (add_accessor_declaration): Implement action.
6779 (remove_accessor_declaration): Implement action.
6780 (event_accessors_declaration): Implement
6781 (variable_declarators): swap statements for first rule - trivial.
6783 * class.cs (Event): New class to hold information about event
6785 (TypeContainer::AddEvent): New method to add an event to a type
6786 (TypeContainer::events): New member to hold list of events.
6788 * cs-parser.jay (event_declaration): Implement actions.
6790 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
6792 * cs-parser.jay (dim_separators): Implement. Make it a string
6793 concatenating all the commas together, just as they appear.
6794 (opt_dim_separators): Modify accordingly
6795 (rank_specifiers): Update accordingly. Basically do the same
6796 thing - instead, collect the brackets here.
6797 (opt_rank_sepcifiers): Modify accordingly.
6798 (array_type): Modify to actually return the complete type string
6799 instead of ignoring the rank_specifiers.
6800 (expression_list): Implement to collect the expressions
6801 (variable_initializer): Implement. We make it a list of expressions
6802 essentially so that we can handle the array_initializer case neatly too.
6803 (variable_initializer_list): Implement.
6804 (array_initializer): Make it a list of variable_initializers
6805 (opt_array_initializer): Modify accordingly.
6807 * expression.cs (New::NType): Add enumeration to help us
6808 keep track of whether we have an object/delegate creation
6809 or an array creation.
6810 (New:NewType, New::Rank, New::Indices, New::Initializers): New
6811 members to hold data about array creation.
6812 (New:New): Modify to update NewType
6813 (New:New): New Overloaded contructor for the array creation
6816 * cs-parser.jay (array_creation_expression): Implement to call
6817 the overloaded New constructor.
6819 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
6821 * class.cs (TypeContainer::Constructors): Return member
6822 constructors instead of returning null.
6824 2001-08-26 Miguel de Icaza <miguel@ximian.com>
6826 * typemanager.cs (InitCoreTypes): Initialize the various core
6827 types after we have populated the type manager with the user
6828 defined types (this distinction will be important later while
6829 compiling corlib.dll)
6831 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
6832 on Expression Classification. Now all expressions have a method
6833 `Resolve' and a method `Emit'.
6835 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
6836 generation from working. Also add some temporary debugging
6839 2001-08-24 Miguel de Icaza <miguel@ximian.com>
6841 * codegen.cs: Lots of code generation pieces. This is only the
6842 beginning, will continue tomorrow with more touches of polish. We
6843 handle the fundamentals of if, while, do, for, return. Others are
6844 trickier and I need to start working on invocations soon.
6846 * gen-treedump.cs: Bug fix, use s.Increment here instead of
6849 * codegen.cs (EmitContext): New struct, used during code
6850 emission to keep a context. Most of the code generation will be
6853 * cs-parser.jay: Add embedded blocks to the list of statements of
6854 this block. So code generation proceeds in a top down fashion.
6856 2001-08-23 Miguel de Icaza <miguel@ximian.com>
6858 * statement.cs: Add support for multiple child blocks.
6860 2001-08-22 Miguel de Icaza <miguel@ximian.com>
6862 * codegen.cs (EmitCode): New function, will emit the code for a
6863 Block of code given a TypeContainer and its ILGenerator.
6865 * statement.cs (Block): Standard public readonly optimization.
6866 (Block::Block constructors): Link children.
6867 (Block::Child): Child Linker.
6868 (Block::EmitVariables): Emits IL variable declarations.
6870 * class.cs: Drop support for MethodGroups here, delay until
6872 (Method::): Applied the same simplification that I did before, and
6873 move from Properties to public readonly fields.
6874 (Method::ParameterTypes): Returns the parameter types for the
6875 function, and implements a cache that will be useful later when I
6876 do error checking and the semantic analysis on the methods is
6878 (Constructor::GetCallingConvention): Renamed from CallingConvetion
6879 and made a method, optional argument tells whether this is a class
6880 or a structure to apply the `has-this' bit.
6881 (Method::GetCallingConvention): Implement, returns the calling
6883 (Method::Define): Defines the type, a second pass is performed
6884 later to populate the methods.
6886 (Constructor::ParameterTypes): implement a cache similar to the
6887 one on Method::ParameterTypes, useful later when we do semantic
6890 (TypeContainer::EmitMethod): New method. Emits methods.
6892 * expression.cs: Removed MethodGroup class from here.
6894 * parameter.cs (Parameters::GetCallingConvention): new method.
6896 2001-08-21 Miguel de Icaza <miguel@ximian.com>
6898 * class.cs (TypeContainer::Populate): Drop RootContext from the
6901 (Constructor::CallingConvention): Returns the calling convention.
6902 (Constructor::ParameterTypes): Returns the constructor parameter
6905 (TypeContainer::AddConstructor): Keep track of default constructor
6906 and the default static constructor.
6908 (Constructor::) Another class that starts using `public readonly'
6909 instead of properties.
6911 (Constructor::IsDefault): Whether this is a default constructor.
6913 (Field::) use readonly public fields instead of properties also.
6915 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
6916 track of static constructors; If none is used, turn on
6917 BeforeFieldInit in the TypeAttributes.
6919 * cs-parser.jay (opt_argument_list): now the return can be null
6920 for the cases where there are no arguments.
6922 (constructor_declarator): If there is no implicit `base' or
6923 `this', then invoke the default parent constructor.
6925 * modifiers.cs (MethodAttr): New static function maps a set of
6926 modifiers flags into a MethodAttributes enum
6927 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
6928 MethodAttr, TypeAttr to represent the various mappings where the
6930 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
6932 2001-08-19 Miguel de Icaza <miguel@ximian.com>
6934 * parameter.cs (GetParameterInfo): Fix bug where there would be no
6937 * interface.cs (PopulateIndexer): Implemented the code generator
6938 for interface indexers.
6940 2001-08-17 Miguel de Icaza <miguel@ximian.com>
6942 * interface.cs (InterfaceMemberBase): Now we track the new status
6945 (PopulateProperty): Implement property population. Woohoo! Got
6946 Methods and Properties going today.
6948 Removed all the properties for interfaces, and replaced them with
6949 `public readonly' fields.
6951 2001-08-16 Miguel de Icaza <miguel@ximian.com>
6953 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
6954 initialize their hashtables/arraylists only when they are needed
6955 instead of doing this always.
6957 * parameter.cs: Handle refs and out parameters.
6959 * cs-parser.jay: Use an ArrayList to construct the arguments
6960 instead of the ParameterCollection, and then cast that to a
6963 * parameter.cs: Drop the use of ParameterCollection and use
6964 instead arrays of Parameters.
6966 (GetParameterInfo): Use the Type, not the Name when resolving
6969 2001-08-13 Miguel de Icaza <miguel@ximian.com>
6971 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
6972 and instead use public readonly fields.
6974 * class.cs: Put back walking code for type containers.
6976 2001-08-11 Miguel de Icaza <miguel@ximian.com>
6978 * class.cs (MakeConstant): Code to define constants.
6980 * rootcontext.cs (LookupType): New function. Used to locate types
6983 2001-08-08 Miguel de Icaza <miguel@ximian.com>
6985 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
6986 this System.Reflection code is. Kudos to Microsoft
6988 * typemanager.cs: Implement a type cache and avoid loading all
6989 types at boot time. Wrap in LookupType the internals. This made
6990 the compiler so much faster. Wow. I rule!
6992 * driver.cs: Make sure we always load mscorlib first (for
6993 debugging purposes, nothing really important).
6995 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
6996 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
6998 * rootcontext.cs: Lookup types on their namespace; Lookup types
6999 on namespaces that have been imported using the `using' keyword.
7001 * class.cs (TypeContainer::TypeAttr): Virtualize.
7002 (Class::TypeAttr): Return attributes suitable for this bad boy.
7003 (Struct::TypeAttr): ditto.
7004 Handle nested classes.
7005 (TypeContainer::) Remove all the type visiting code, it is now
7006 replaced with the rootcontext.cs code
7008 * rootcontext.cs (GetClassBases): Added support for structs.
7010 2001-08-06 Miguel de Icaza <miguel@ximian.com>
7012 * interface.cs, statement.cs, class.cs, parameter.cs,
7013 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
7014 Drop use of TypeRefs, and use strings instead.
7016 2001-08-04 Miguel de Icaza <miguel@ximian.com>
7020 * class.cs (Struct::Struct): set the SEALED flags after
7021 checking the modifiers.
7022 (TypeContainer::TypeAttr): new property, returns the
7023 TypeAttributes for a class.
7025 * cs-parser.jay (type_list): Oops, list production was creating a
7026 new list of base types.
7028 * rootcontext.cs (StdLib): New property.
7029 (GetInterfaceTypeByName): returns an interface by type name, and
7030 encapsulates error handling here.
7031 (GetInterfaces): simplified.
7032 (ResolveTree): Encapsulated all the tree resolution here.
7033 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
7036 * driver.cs: Add support for --nostdlib, to avoid loading the
7038 (Main): Do not put tree resolution here.
7040 * rootcontext.cs: Beginning of the class resolution.
7042 2001-08-03 Miguel de Icaza <miguel@ximian.com>
7044 * rootcontext.cs: Provide better error reporting.
7046 * cs-parser.jay (interface_base): set our $$ to be interfaces.
7048 * rootcontext.cs (CreateInterface): Handle the case where there
7049 are no parent interfaces.
7051 (CloseTypes): Routine to flush types at the end.
7052 (CreateInterface): Track types.
7053 (GetInterfaces): Returns an array of Types from the list of
7056 * typemanager.c (AddUserType): Mechanism to track user types (puts
7057 the type on the global type hash, and allows us to close it at the
7060 2001-08-02 Miguel de Icaza <miguel@ximian.com>
7062 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
7063 RecordInterface instead.
7065 * cs-parser.jay: Updated to reflect changes above.
7067 * decl.cs (Definition): Keep track of the TypeBuilder type that
7068 represents this type here. Not sure we will use it in the long
7069 run, but wont hurt for now.
7071 * driver.cs: Smaller changes to accomodate the new code.
7073 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
7076 * rootcontext.cs (CreateInterface): New method, used to create
7077 the System.TypeBuilder type for interfaces.
7078 (ResolveInterfaces): new entry point to resolve the interface
7080 (CodeGen): Property, used to keep track of the code generator.
7082 2001-07-26 Miguel de Icaza <miguel@ximian.com>
7084 * cs-parser.jay: Add a second production for delegate_declaration
7087 (enum_body): Put an opt_comma here instead of putting it on
7088 enum_body or enum_member_declarations so we can handle trailing
7089 commas on enumeration members. Gets rid of a shift/reduce.
7091 (type_list): Need a COMMA in the middle.
7093 (indexer_declaration): Tell tokenizer to recognize get/set
7095 * Remove old targets.
7097 * Re-add the parser target.
7099 2001-07-13 Simon Cozens <simon@simon-cozens.org>
7101 * cs-parser.jay: Add precendence rules for a number of operators
7102 ot reduce the number of shift/reduce conflicts in the grammar.
7104 2001-07-17 Miguel de Icaza <miguel@ximian.com>
7106 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
7109 Get rid of old crufty code.
7111 * rootcontext.cs: Use this to keep track of the parsed
7112 representation and the defined types available to the program.
7114 * gen-treedump.cs: adjust for new convention.
7116 * type.cs: Split out the type manager, and the assembly builder
7119 * typemanager.cs: the type manager will live here now.
7121 * cil-codegen.cs: And the code generator here.
7123 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
7125 * makefile: Fixed up for easy making.
7127 2001-07-13 Simon Cozens <simon@simon-cozens.org>
7129 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
7132 (unary_expression): Expand pre_increment_expression and
7133 post_decrement_expression to reduce a shift/reduce.
7135 2001-07-11 Simon Cozens
7137 * cs-tokenizer.cs: Hex numbers should begin with a 0.
7139 Improve allow_keyword_as_indent name.
7141 2001-06-19 Miguel de Icaza <miguel@ximian.com>
7143 * Adjustments for Beta2.
7145 2001-06-13 Miguel de Icaza <miguel@ximian.com>
7147 * decl.cs: Added `Define' abstract method.
7148 (InTransit): new property, used to catch recursive definitions.
7150 * interface.cs: Implement `Define'.
7152 * modifiers.cs: Map Modifiers.constants to
7153 System.Reflection.TypeAttribute flags.
7155 * class.cs: Keep track of types and user-defined types.
7156 (BuilderInit): New method for creating an assembly
7157 (ResolveType): New function to launch the resolution process, only
7158 used by interfaces for now.
7160 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
7161 that are inserted into the name space.
7163 2001-06-08 Miguel de Icaza <miguel@ximian.com>
7165 * ARGH. I have screwed up my tree so many times due to the use of
7166 rsync rather than using CVS. Going to fix this at once.
7168 * driver.cs: Objetify driver. Load assemblies, use assemblies to
7171 2001-06-07 Miguel de Icaza <miguel@ximian.com>
7173 * Experiment successful: Use System.Type rather that our own
7176 2001-05-25 Miguel de Icaza <miguel@ximian.com>
7178 * cs-parser.jay: Removed nsAliases from here.
7180 Use new namespaces, handle `using XXX;'
7182 * namespace.cs: Reimplemented namespace handling, use a recursive
7183 definition of the class. Now we can keep track of using clauses
7184 and catch invalid using clauses.
7186 2001-05-24 Miguel de Icaza <miguel@ximian.com>
7188 * gen-treedump.cs: Adapted for all the renaming.
7190 * expression.cs (Expression): this class now has a Type property
7191 which returns an expression Type.
7193 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
7194 `Type', as this has a different meaning now in the base
7196 2001-05-22 Miguel de Icaza <miguel@ximian.com>
7198 * interface.cs, class.cs: Removed from all the sources the
7199 references to signature computation, as we can not do method
7200 signature computation during the parsing time, as we are not
7201 trying to solve at that point distinguishing:
7205 void a (NS.Blah x) {}
7208 Which depending on the context might be valid or not, as we do not
7209 know if Blah is the same thing as NS.Blah at that point.
7211 * Redid everything so the code uses TypeRefs now instead of
7212 Types. TypeRefs are just temporary type placeholders, that need
7213 to be resolved. They initially have a pointer to a string and the
7214 current scope in which they are used. This is used later by the
7215 compiler to resolve the reference to an actual Type.
7217 * DeclSpace is no longer a CIR.Type, and neither are
7218 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
7219 are all DeclSpaces, but no Types.
7221 * type.cs (TypeRefManager): This implements the TypeRef manager,
7222 which keeps track of all the types that need to be resolved after
7223 the parsing has finished.
7225 2001-05-13 Miguel de Icaza <miguel@ximian.com>
7227 * ARGH. We are going to have to store `foreach' as a class rather
7228 than resolving it, as we need to verify error 1579 after name
7229 resolution. *OR* we could keep a flag that says `This request to
7230 IEnumerator comes from a foreach statement' which we can then use
7231 to generate the error.
7233 2001-05-10 Miguel de Icaza <miguel@ximian.com>
7235 * class.cs (TypeContainer.AddMethod): we now add methods to the
7236 MethodGroup instead of the method hashtable.
7238 * expression.cs: Add MethodGroup abstraction, which gets us one
7239 step closer to the specification in the way we handle method
7242 * cs-parser.jay (primary_expression): qualified_identifier now
7243 tried to match up an identifier to a local variable reference or
7244 to a parameter reference.
7246 current_local_parameters is now a parser global variable that
7247 points to the current parameters for the block, used during name
7250 (property_declaration): Now creates an implicit `value' argument to
7253 2001-05-09 Miguel de Icaza <miguel@ximian.com>
7255 * parameter.cs: Do not use `param' arguments as part of the
7256 signature, per the spec.
7258 2001-05-08 Miguel de Icaza <miguel@ximian.com>
7260 * decl.cs: Base class for classes, structs and interfaces. This
7261 is the "Declaration Space"
7263 * cs-parser.jay: Use CheckDef for checking declaration errors
7264 instead of having one on each function.
7266 * class.cs: Factor out some code for handling error handling in
7267 accordance to the "Declarations" section in the "Basic Concepts"
7268 chapter in the ECMA C# spec.
7270 * interface.cs: Make all interface member classes derive from
7271 InterfaceMemberBase.
7273 2001-05-07 Miguel de Icaza <miguel@ximian.com>
7275 * Many things: all interfaces are parsed and generated in
7276 gen-treedump. Support for member variables, constructors,
7277 destructors, properties, constants is there.
7279 Beginning of the IL backend, but very little done, just there for
7282 2001-04-29 Miguel de Icaza <miguel@ximian.com>
7284 * cs-parser.jay: Fix labeled statement.
7286 * cs-tokenizer.cs (escape): Escape " and ' always.
7287 ref_line, ref_name: keep track of the line/filename as instructed
7288 by #line by the compiler.
7291 2001-04-27 Miguel de Icaza <miguel@ximian.com>
7293 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
7294 to match the values in System.CodeDOM.
7296 Divid renamed to Divide.
7298 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
7300 (Statements.set): remove.
7302 * System.CodeDOM/CodeCatchClause.cs: always have a valid
7305 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
7306 falseStatements always have valid values.
7308 * cs-parser.jay: Use System.CodeDOM now.
