3 * typemanager.cs (TypeManager.GetArgumentTypes): Don't call
4 PropertyInfo.GetIndexParameters() on dynamic types, this doesn't
5 work with the ms runtime and we also don't need it: if we're a
6 PropertyBuilder and not in the `indexer_arguments' hash, then we
7 are a property and not an indexer.
9 * class.cs (TypeContainer.AsAccessible): Use Type.IsArray,
10 Type.IsPointer and Type.IsByRef instead of Type.HasElementType
11 since the latter one doesn't work with the ms runtime.
13 2002-08-03 Martin Baulig <martin@gnome.org>

73 2002-08-02 Martin Baulig <martin@gnome.org>
75 * expression.cs (LocalVariableReferenc): Added constructor which
76 takes additional `VariableInfo vi' and `bool is_readonly' arguments.
77 (LocalVariableReference.IsReadOnly): New property.

116 `hm.is_disposable' if we're using the collection pattern.
117 (Foreach.EmitCollectionForeach): Use the correct type for the
118 enumerator's local variable, only emit the try/finally block if
119 necessary (fixes #27713).
121 2002-08-01 Martin Baulig <martin@gnome.org>
123 * ecore.cs (Expression.report118): Renamed to Error118 and made
126 * statement.cs (Throw.Resolve): Check whether the expression is of
127 the correct type (CS0118) and whether the type derives from
128 System.Exception (CS0155).
129 (Catch.Resolve): New method. Do the type lookup here and check
130 whether it derives from System.Exception (CS0155).
131 (Catch.CatchType, Catch.IsGeneral): New public properties.

195 * statement.cs (Fixed): Moved all code that does variable lookups
196 and resolvings from Emit to Resolve.
198 * statement.cs (For): Moved all code that does variable lookups
199 and resolvings from Emit to Resolve.
201 * statement.cs (Using): Moved all code that does variable lookups
202 and resolvings from Emit to Resolve.
204 2002-07-29 Martin Baulig <martin@gnome.org>
206 * attribute.cs (Attribute.Resolve): Explicitly catch a

273 Fixes bug #24007, added test-152.cs.
275 2002-07-27 Martin Baulig <martin@gnome.org>
277 * expression.cs (Invocation.EmitArguments): When calling a varargs
278 function with only its fixed arguments, we need to pass an empty
281 2002-07-27 Martin Baulig <martin@gnome.org>
283 Mono 0.13 has been released.
285 2002-07-25 Miguel de Icaza <miguel@ximian.com>
287 * driver.cs: Rename --resource to --linkres, because that is what
288 we do currently, we dont support --resource yet.
290 * cs-tokenizer.cs: Fix test for reporting endif mismatches.
292 2002-07-25 Martin Baulig <martin@gnome.org>
294 * class.cs (MethodData): New public class. This is a `method builder'
295 class for a method or one accessor of a Property/Indexer/Event.
296 (MethodData.GetMethodFlags): Moved here from MemberBase.
297 (MethodData.ApplyAttributes): Likewise.
298 (MethodData.ApplyObsoleteAttribute): Likewise.
299 (MethodData.ApplyConditionalAttribute): Likewise.
300 (MethodData.ApplyDllImportAttribute): Likewise.
301 (MethodData.CheckAbstractAndExternal): Likewise.
302 (MethodData.Define): Formerly knows as MemberBase.DefineMethod().
303 (MethodData.Emit): Formerly known as Method.Emit().
304 (MemberBase): Moved everything which was specific to a single
305 accessor/method to MethodData.
306 (Method): Create a new MethodData and call Define() and Emit() on it.
307 (Property, Indexer, Event): Create a new MethodData objects for each
308 accessor and call Define() and Emit() on them.
310 2002-07-25 Martin Baulig <martin@gnome.org>
312 Made MethodCore derive from MemberBase to reuse the code from there.
313 MemberBase now also checks for attributes.
315 * class.cs (MethodCore): Derive from MemberBase, not MemberCore.
316 (MemberBase.GetMethodFlags): Moved here from class Method and marked
318 (MemberBase.DefineAccessor): Renamed to DefineMethod(), added
319 `CallingConventions cc' and `Attributes opt_attrs' arguments.
320 (MemberBase.ApplyAttributes): New virtual method; applies the
321 attributes to a method or accessor.
322 (MemberBase.ApplyObsoleteAttribute): New protected virtual method.
323 (MemberBase.ApplyConditionalAttribute): Likewise.
324 (MemberBase.ApplyDllImportAttribute): Likewise.
325 (MemberBase.CheckAbstractAndExternal): Likewise.

330 initialize ParameterTypes and ParameterInfo.
331 (Method.GetReturnType): We can now simply return the MemberType.
332 (Method.GetMethodFlags): Override the MemberBase version and add
333 the conditional flags.
334 (Method.CheckBase): Moved some code from Define() here, call
335 DoDefineParameters() here.
336 (Method.Define): Use DoDefine() and DefineMethod() from MemberBase
337 here to avoid some larger code duplication.
338 (Property.Emit, Indexer.Emit): Call CheckAbstractAndExternal() to
339 ensure that abstract and external accessors don't declare a body.
341 * attribute.cs (Attribute.GetValidPieces): Make this actually work:
342 `System.Attribute.GetCustomAttributes (attr.Type)' does a recursive
343 lookup in the attribute's parent classes, so we need to abort as soon
344 as we found the first match.
345 (Attribute.Obsolete_GetObsoleteMessage): Return the empty string if
346 the attribute has no arguments.
348 * typemanager.cs (TypeManager.AddMethod): Now takes a MemberBase instead
351 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
353 * cs-parser.jay: reverted previous patch.
355 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
357 * cs-parser.jay: fixed bug #22119.
359 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
361 * attribute.cs: fixed compilation. The error was:
362 "attribute.cs(571,17): error CS0177: The out parameter 'is_error' must
363 be assigned to before control leaves the current method."
364 [FIXME: Filed as bug #28186: MCS must report this error.]
366 2002-07-25 Martin Baulig <martin@gnome.org>
368 * attribute.cs (Attribute.Conditional_GetConditionName): New static
369 method to pull the condition name ouf of a Conditional attribute.
370 (Attribute.Obsolete_GetObsoleteMessage): New static method to pull
371 the obsolete message and error flag out of an Obsolete attribute.
373 * class.cs (Method.GetMethodFlags): New public method to get the
374 TypeManager.MethodFlags for this method.
375 (Method.ApplyConditionalAttribute, Method.ApplyObsoleteAttribute): New
377 (Method.Define): Get and apply the Obsolete and Conditional attributes;
378 if we're overriding a virtual function, set the new private variable
379 `parent_method'; call the new TypeManager.AddMethod().
381 * typemanager.cs (TypeManager.AddMethod): New static method. Stores
382 the MethodBuilder and the Method in a PtrHashtable.
383 (TypeManager.builder_to_method): Added for this purpose.
384 (TypeManager.MethodFlags): Added IsObsoleteError.
385 (TypeManager.GetMethodFlags): Added `Location loc' argument. Lookup
386 Obsolete and Conditional arguments in MethodBuilders. If we discover
387 an Obsolete attribute, emit an appropriate warning 618 / error 619 with
388 the message from the attribute.
390 2002-07-24 Martin Baulig <martin@gnome.org>
392 * cs-tokenizer.cs: Eat up trailing whitespaces and one-line comments in
393 preprocessor directives, ensure that the argument to #define/#undef is
394 exactly one identifier and that it's actually an identifier.
396 Some weeks ago I did a `#define DEBUG 1' myself and wondered why this
399 2002-07-24 Martin Baulig <martin@gnome.org>
401 * statement.cs (Foreach.ForeachHelperMethods): Added `Type element_type',
402 initialize it to TypeManager.object_type in the constructor.
403 (Foreach.GetEnumeratorFilter): Set `hm.element_type' to the return type
404 of the `hm.get_current' method if we're using the collection pattern.
405 (Foreach.EmitCollectionForeach): Use `hm.element_type' as the source type
406 for the explicit conversion to make it work when we're using the collection
407 pattern and the `Current' property has a different return type than `object'.
410 2002-07-24 Martin Baulig <martin@gnome.org>
412 * delegate.cs (Delegate.VerifyMethod): Simply return null if the method
413 does not match, but don't report any errors. This method is called in
414 order for all methods in a MethodGroupExpr until a matching method is
415 found, so we don't want to bail out if the first method doesn't match.
416 (NewDelegate.DoResolve): If none of the methods in the MethodGroupExpr
417 matches, report the 123. Fixes #28070.
419 2002-07-24 Martin Baulig <martin@gnome.org>
421 * expression.cs (ArrayAccess.EmitStoreOpcode): Moved the
422 TypeManager.TypeToCoreType() to the top of the method so the
423 following equality checks will work. Fixes #28107.
425 2002-07-24 Martin Baulig <martin@gnome.org>
427 * cfold.cs (ConstantFold.DoConstantNumericPromotions): "If either
428 operand is of type uint, and the other operand is of type sbyte,
429 short or int, the operands are converted to type long." -
430 Actually do what this comment already told us. Fixes bug #28106,
433 2002-07-24 Martin Baulig <martin@gnome.org>
435 * class.cs (MethodBase): New abstract class. This is now a base
436 class for Property, Indexer and Event to avoid some code duplication
437 in their Define() and DefineMethods() methods.
438 (MethodBase.DoDefine, MethodBase.DefineAccessor): Provide virtual
439 generic methods for Define() and DefineMethods().
440 (FieldBase): Derive from MemberBase, not MemberCore.
441 (Property): Derive from MemberBase, not MemberCore.
442 (Property.DefineMethod): Moved all the code from this method to the
443 new MethodBase.DefineAccessor(), just call it with appropriate
445 (Property.Define): Call the new Property.DoDefine(), this does some
446 sanity checks and we don't need to duplicate the code everywhere.
447 (Event): Derive from MemberBase, not MemberCore.
448 (Event.Define): Use the new MethodBase.DefineAccessor() to define the
449 accessors, this will also make them work with interface events.
450 (Indexer): Derive from MemberBase, not MemberCore.
451 (Indexer.DefineMethod): Removed, call MethodBase.DefineAccessor() insstead.
452 (Indexer.Define): Use the new MethodBase functions.
454 * interface.cs (InterfaceEvent.InterfaceEvent): Added `Location loc'
455 argument to the constructor.
456 (Interface.FindMembers): Added support for interface events.
457 (Interface.PopluateEvent): Implemented.
459 Added test-149.cs for this. This also fixes bugs #26067 and #24256.
461 2002-07-22 Miguel de Icaza <miguel@ximian.com>
463 * class.cs (TypeContainer.AddMethod): Adding methods do not use IsValid,
464 but this is required to check for a method name being the same as
465 the containing class.
469 2002-07-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
471 * interface.cs: initialize variable.
473 2002-07-23 Martin Baulig <martin@gnome.org>
475 Implemented the IndexerName attribute in interfaces.
477 * class.cs (TypeContainer.DefineIndexers): Don't set the indexer
478 name if this is an explicit interface implementation.
479 (Indexer.InterfaceIndexerName): New public variable. If we're
480 implementing an interface indexer, this is the IndexerName in that
481 interface. Otherwise, it's the IndexerName.
482 (Indexer.DefineMethod): If we're implementing interface indexer,
483 set InterfaceIndexerName. Use the new Pending.IsInterfaceIndexer
484 and Pending.ImplementIndexer methods.
485 (Indexer.Define): Also define the PropertyBuilder if we're
486 implementing an interface indexer and this is neither an explicit
487 interface implementation nor do the IndexerName match the one in
490 * pending.cs (TypeAndMethods): Added `MethodInfo [] need_proxy'.
491 If a method is defined here, then we always need to create a proxy
492 for it. This is used when implementing interface indexers.
493 (Pending.IsInterfaceIndexer): New public method.
494 (Pending.ImplementIndexer): New public method.
495 (Pending.InterfaceMethod): Added `MethodInfo need_proxy' argument.
496 This is used when implementing interface indexers to define a proxy
498 (Pending.VerifyPendingMethods): Look in the `need_proxy' array and
499 define a proxy if necessary.
501 * interface.cs (Interface.IndexerName): New public variable.
502 (Interface.PopulateIndexer): Set the IndexerName.
503 (Interface.DefineIndexers): New private method. Populate all the
504 indexers and make sure their IndexerNames match.
506 * typemanager.cs (IndexerPropertyName): Added support for interface
509 2002-07-22 Martin Baulig <martin@gnome.org>
511 * codegen.cs (EmitContext.HasReturnLabel): New public variable.
512 (EmitContext.EmitTopBlock): Always mark the ReturnLabel and emit a
513 ret if HasReturnLabel.
514 (EmitContext.TryCatchLevel, LoopBeginTryCatchLevel): New public
517 * statement.cs (Do.Emit, While.Emit, For.Emit, Foreach.Emit): Save
518 and set the ec.LoopBeginTryCatchLevel.
519 (Try.Emit): Increment the ec.TryCatchLevel while emitting the block.
520 (Continue.Emit): If the ec.LoopBeginTryCatchLevel is smaller than
521 the current ec.TryCatchLevel, the branch goes out of an exception
522 block. In this case, we need to use Leave and not Br.
524 2002-07-22 Martin Baulig <martin@gnome.org>
526 * statement.cs (Try.Emit): Emit an explicit ret after the end of the
527 block unless the block does not always return or it is contained in
528 another try { ... } catch { ... } block. Fixes bug #26506.
529 Added verify-1.cs to the test suite.
531 2002-07-22 Martin Baulig <martin@gnome.org>
533 * statement.cs (Switch.TableSwitchEmit): If we don't have a default,
534 then we do not always return. Fixes bug #24985.
536 2002-07-22 Martin Baulig <martin@gnome.org>
538 * expression.cs (Invocation.OverloadedResolve): Do the BetterFunction()
539 lookup on a per-class level; ie. walk up the class hierarchy until we
540 found at least one applicable method, then choose the best among them.
541 Fixes bug #24463 and test-29.cs.
543 2002-07-22 Martin Baulig <martin@gnome.org>
545 * typemanager.cs (TypeManager.ArrayContainsMethod): Don't check the
546 return types of the methods. The return type is not part of the
547 signature and we must not check it to make the `new' modifier work.
548 Fixes bug #27999, also added test-147.cs.
549 (TypeManager.TypeToCoreType): Added TypeManager.type_type.
551 * expression.cs (Invocation.DoResolve): Call TypeManager.TypeToCoreType()
552 on the method's return type.
554 2002-07-21 Martin Baulig <martin@gnome.org>
556 * assign.cs: Make this work if the rightmost source is a constant and
557 we need to do an implicit type conversion. Also adding a few more tests
558 to test-38.cs which should have caught this.
560 * makefile.gnu: Disable debugging, there's already the mcs-mono2.exe
561 target in the makefile for this. The makefile.gnu is primarily intended
562 for end-users who don't want to debug the compiler.
564 2002-07-21 Martin Baulig <martin@gnome.org>
566 * assign.cs: Improved the Assign class so it can now handle embedded
567 assignments (X = Y = Z = something). As a side-effect this'll now also
568 consume less local variables. test-38.cs now passes with MCS, added
569 a few new test cases to that test.
571 2002-07-20 Martin Baulig <martin@gnome.org>
573 * expression.cs (Binary.EmitBranchable): Emit correct unsigned branch
574 instructions. Fixes bug #27977, also added test-146.cs.
576 2002-07-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
578 * cs-tokenizer.cs: fixed getHex ().
580 2002-07-19 Martin Baulig <martin@gnome.org>
582 * expression.cs (Invocation.EmitParams): Use TypeManager.LookupType(),
583 not Type.GetType() to lookup the array type. This is needed when
584 we're constructing an array of a user-defined type.
585 (ArrayAccess.EmitDynamicInitializers): Only emit the Ldelema for
586 single-dimensional arrays, but also for single-dimensial arrays of
589 2002-07-19 Martin Baulig <martin@gnome.org>
591 * expression.cs (New.DoEmit): Create a new LocalTemporary each time
592 this function is called, it's not allowed to share LocalBuilders
595 2002-07-19 Martin Baulig <martin@gnome.org>
597 * expression.cs (Argument.Resolve): Report an error 118 when trying
598 to pass a type as argument.
600 2002-07-18 Martin Baulig <martin@gnome.org>
602 * ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
603 Conv_R_Un for the signed `long' type.
605 2002-07-15 Miguel de Icaza <miguel@ximian.com>
607 * expression.cs (MemberAccess.DoResolve): Do not reuse the field
608 `expr' for the temporary result, as that will fail if we do
609 multiple resolves on the same expression.
611 2002-07-05 Miguel de Icaza <miguel@ximian.com>
613 * ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
614 ec.TypeContainer for looking up aliases.
616 * class.cs (TypeContainer): Remove LookupAlias from here.
618 * decl.cs (DeclSpace); Move here.
620 2002-07-01 Miguel de Icaza <miguel@ximian.com>
622 * class.cs (FindMembers): Only call filter if the constructor
625 Also handle delegates in `NestedTypes' now. Now we will perform
626 type lookups using the standard resolution process. This also
629 * decl.cs (DeclSpace.ResolveType): New type resolution routine.
630 This uses Expressions (the limited kind that can be parsed by the
631 tree) instead of strings.
633 * expression.cs (ComposedCast.ToString): Implement, used to flag
634 errors since now we have to render expressions.
636 (ArrayCreation): Kill FormElementType. Use ComposedCasts in
639 * ecore.cs (SimpleName.ToString): ditto.
641 * cs-parser.jay: Instead of using strings to assemble types, use
642 Expressions to assemble the type (using SimpleName, ComposedCast,
643 MemberAccess). This should fix the type lookups in declarations,
644 because we were using a different code path for this.
646 * statement.cs (Block.Resolve): Continue processing statements
647 even when there is an error.
649 2002-07-17 Miguel de Icaza <miguel@ximian.com>
651 * class.cs (Event.Define): Also remove the `remove' method from
652 the list of pending items.
654 * expression.cs (ParameterReference): Use ldarg.N (0..3) to
655 generate more compact code.
657 2002-07-17 Martin Baulig <martin@gnome.org>
659 * const.cs (Const.LookupConstantValue): Add support for constant
660 `unchecked' and `checked' expressions.
661 Also adding test case test-140.cs for this.
663 2002-07-17 Martin Baulig <martin@gnome.org>
665 * statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
666 check whether mi.ReturnType implements the IEnumerator interface; the
667 `==' and the IsAssignableFrom() will fail in this situation.
669 2002-07-16 Ravi Pratap <ravi@ximian.com>
671 * ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix
674 2002-07-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
676 * expression.cs: fixed bug #27811.
678 2002-07-14 Miguel de Icaza <miguel@ximian.com>
680 * expression.cs (ParameterReference.AddressOf): Patch from Paolo
681 Molaro: when we are a ref, the value already contains a pointer
682 value, do not take the address of it.
684 2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
685 * removed mb-parser.jay and mb-tokenizer.cs
687 Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
689 * expression.cs: check against the building corlib void type.
691 Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
693 * ecore.cs: fix for valuetype static readonly fields: when
694 initializing them, we need their address, not the address of a copy.
696 Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
698 * typemanager.cs: register also enum_type in corlib.
700 Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
702 * class.cs: allow calling this (but not base) initializers in structs.
704 Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
706 * ecore.cs: make sure we compare against the building base types
709 Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
711 * typemanager.cs: fix TypeToCoreType() to handle void and object
712 (corlib gets no more typerefs after this change).
714 2002-07-12 Miguel de Icaza <miguel@ximian.com>
716 * expression.cs (ArrayCreation.EmitArrayArguments): use
717 Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
719 (ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
720 Conv_Ovf_I_Un for the array arguments. Even if C# allows longs as
721 array indexes, the runtime actually forbids them.
723 * ecore.cs (ExpressionToArrayArgument): Move the conversion code
724 for array arguments here.
726 * expression.cs (EmitLoadOpcode): System.Char is a U2, use that
727 instead of the default for ValueTypes.
729 (New.DoEmit): Use IsValueType instead of
730 IsSubclassOf (value_type)
731 (New.DoResolve): ditto.
732 (Invocation.EmitCall): ditto.
734 * assign.cs (Assign): ditto.
736 * statement.cs (Unsafe): Ok, so I got the semantics wrong.
737 Statements *are* currently doing part of their resolution during
740 Expressions do always resolve during resolve, but statements are
741 only required to propagate resolution to their children.
743 2002-07-11 Miguel de Icaza <miguel@ximian.com>
745 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
747 (LoadAssembly): Do not add the dll if it is already specified
749 (MainDriver): Add the System directory to the link path at the end,
750 after all the other -L arguments.
752 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
753 wrong opcode for loading bytes and bools (ldelem.i1 instead of
754 ldelem.u1) and using the opposite for sbytes.
756 This fixes Digger, and we can finally run it.
758 * driver.cs (UnixParseOption): Move the option parsing here.
759 (CSCParseOption): Implement CSC-like parsing of options.
761 We now support both modes of operation, the old Unix way, and the
762 new CSC-like way. This should help those who wanted to make cross
765 The only thing broken is that /r:, /reference: and /lib: are not
766 implemented, because I want to make those have the same semantics
767 as the CSC compiler has, and kill once and for all the confussion
768 around this. Will be doing this tomorrow.
770 * statement.cs (Unsafe.Resolve): The state is checked during
771 resolve, not emit, so we have to set the flags for IsUnsfe here.
773 2002-07-10 Miguel de Icaza <miguel@ximian.com>
775 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
776 not catch the Error_ObjectRefRequired in SimpleName (as it is
777 possible to have a class/instance variable name that later gets
778 deambiguated), we have to check this here.
780 2002-07-10 Ravi Pratap <ravi@ximian.com>
782 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
783 make static and put into Expression.
785 (Event.Define): Register the private field of the event with the
786 TypeManager so that GetFieldFromEvent can get at it.
788 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
789 keep track of the private field associated with an event which
792 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
795 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
797 2002-07-10 Miguel de Icaza <miguel@ximian.com>
799 * expression.cs (Binary.EmitBranchable): this routine emits the
800 Binary expression in a branchable context. This basically means:
801 we need to branch somewhere, not just get the value on the stack.
803 This works together with Statement.EmitBoolExpression.
805 * statement.cs (Statement.EmitBoolExpression): Use
808 2002-07-09 Miguel de Icaza <miguel@ximian.com>
810 * statement.cs (For): Reduce the number of jumps in loops.
812 (For): Implement loop inversion for the For statement.
814 (Break): We can be breaking out of a Try/Catch controlled section
815 (foreach might have an implicit try/catch clause), so we need to
816 use Leave instead of Br.
818 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
819 now). If the instace expression supports IMemoryLocation, we use
820 the AddressOf method from the IMemoryLocation to extract the
821 address instead of emitting the instance.
823 This showed up with `This', as we were emitting the instance
824 always (Emit) instead of the Address of This. Particularly
825 interesting when This is a value type, as we dont want the Emit
826 effect (which was to load the object).
828 2002-07-08 Miguel de Icaza <miguel@ximian.com>
830 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
832 * statement.cs (Checked): Set the CheckedState during the resolve
833 process too, as the ConvCast operations track the checked state on
834 the resolve process, and not emit.
836 * cs-parser.jay (namespace_member_declaration): Flag that we have
837 found a declaration when we do. This is used to flag error 1529
839 * driver.cs: Report ok when we display the help only.
841 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
843 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
845 2002-07-04 Miguel de Icaza <miguel@ximian.com>
847 * cs-tokenizer.cs (define): We also have to track locally the
848 defines. AllDefines is just used for the Conditional Attribute,
849 but we also need the local defines for the current source code.
851 2002-07-03 Miguel de Icaza <miguel@ximian.com>
853 * statement.cs (While, For, Do): These loops can exit through a
854 Break statement, use this information to tell whether the
855 statement is the last piece of code.
857 (Break): Flag that we break.
859 * codegen.cs (EmitContexts): New `Breaks' state variable.
861 2002-07-03 Martin Baulig <martin@gnome.org>
863 * class.cs (TypeContainer.MethodModifiersValid): Allow override
864 modifiers in method declarations in structs. Otherwise, you won't
865 be able to override things like Object.Equals().
867 2002-07-02 Miguel de Icaza <miguel@ximian.com>
869 * class.cs (Method, Property, Indexer): Do not allow the public
870 modifier to be used in explicit interface implementations.
872 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
873 override modifiers in method declarations in structs
875 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
877 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
878 integer or real overflow, report an error
880 2002-07-02 Martin Baulig <martin@gnome.org>
882 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
883 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
884 to tell the runtime about our newly created System.Object and
885 System.ValueType types.
887 2002-07-02 Miguel de Icaza <miguel@ximian.com>
889 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
890 struct instead of Ldarg/Starg.
892 2002-07-02 Martin Baulig <martin@gnome.org>
894 * expression.cs (Indirection.Indirection): Call
895 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
897 2002-07-02 Martin Baulig <martin@gnome.org>
899 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
900 ValueType, call TypeManager.TypeToCoreType() on it.
901 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
902 the OpCodes.Newarr argument.
904 2002-07-02 Martin Baulig <martin@gnome.org>
906 * expression.cs (Invocation.EmitCall): When compiling corlib,
907 replace all calls to the system's System.Array type to calls to
908 the newly created one.
910 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
911 System.Array methods.
912 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
913 from the system's System.Array type which must be replaced.
915 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
917 * typemanager.cs: load unverifiable_code_ctor so we can build
918 corlib using the correct type. Avoid using GetTypeCode() with
920 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
921 TypeManager.object_type to allow building corlib.
923 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
925 * ecore.cs: handle System.Enum separately in LoadFromPtr().
927 2002-07-01 Martin Baulig <martin@gnome.org>
929 * class.cs: Make the last change actually work, we need to check
930 whether `ifaces != null' to avoid a crash.
932 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
934 * class.cs: when we build structs without fields that implement
935 interfaces, we need to add the interfaces separately, since there is
936 no API to both set the size and add the interfaces at type creation
939 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
941 * expression.cs: the dimension arguments to the array constructors
942 need to be converted if they are a long.
944 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
946 * class.cs: don't emit ldarg.0 if there is no parent constructor
947 (fixes showstopper for corlib).
949 2002-06-29 Martin Baulig <martin@gnome.org>
951 MCS now compiles corlib on GNU/Linux :-)
953 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
954 ie. check for MethodImplOptions.InternalCall.
956 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
957 and TypeManager.attribute_type are null, so we must explicitly check
958 whether parent is not null to find out whether it's an attribute type.
959 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
960 and SetBuilder, not only if the property is neither abstract nor external.
961 This is necessary to set the MethodImplOptions on the accessor methods.
962 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
963 SetBuilder, see Property.Emit().
965 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
966 populate "System.Object", "System.ValueType" and "System.Attribute" since
967 they've already been populated from BootCorlib_PopulateCoreTypes().
969 2002-06-29 Martin Baulig <martin@gnome.org>
971 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
972 is the NullLiteral, we also need to make sure that target_type is not
975 2002-06-29 Martin Baulig <martin@gnome.org>
977 * rootcontext.cs (RootContext.ResolveCore): We must initialize
978 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
979 before calling BootstrapCorlib_ResolveDelegate ().
981 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
983 * statement.cs: fixed build-breaker. All tests passed ok.
985 2002-06-27 Martin Baulig <martin@gnome.org>
987 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
988 for System.Decimal when compiling corlib.
990 2002-06-27 Martin Baulig <martin@gnome.org>
992 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
993 switch blocks which contain nothing but a default clause.
995 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
997 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
999 2002-06-27 Martin Baulig <martin@gnome.org>
1001 * ecore.cs (PropertyExpr.PropertyExpr): Call
1002 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
1004 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
1005 is already a TypeBuilder.
1007 2002-06-27 Martin Baulig <martin@gnome.org>
1009 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
1010 `target_type == TypeManager.array_type', not IsAssignableFrom() in
1011 the "from an array-type to System.Array" case. This makes it work
1012 when compiling corlib.
1014 2002-06-27 Martin Baulig <martin@gnome.org>
1016 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
1017 non-static PropertyExpr, set its InstanceExpression. This makes
1018 the `ICollection.Count' property work in System/Array.cs.
1020 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
1022 * driver.cs: Made error handling more consistent. Errors now
1023 tracked by Report class, so many methods which used to return int
1024 now return void. Main() now prints success/failure and
1025 errors/warnings message.
1027 Renamed '--probe' compiler argument to '--expect-error'. Removed
1028 the magic number return values (123 and 124). Now, if the
1029 expected error occurs, the compiler exits with success (exit value
1030 0). If the compilation completes without seeing that particular
1031 error, the compiler exits with failure (exit value 1). The
1032 makefile in mcs/errors has been changed to handle the new behaviour.
1034 * report.cs: Made 'expected error' number a property and renamed
1035 it from 'Probe' to 'ExpectedError'.
1037 * genericparser.cs: Removed error handling support, since it is
1038 now all done by Report class.
1040 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
1041 class, so parse() no longer returns an int.
1043 * namespace.cs: Use Report.Error instead of GenericParser.error
1045 2002-06-22 Miguel de Icaza <miguel@ximian.com>
1047 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
1048 TypeContainer.AddOperator): At the front of the list put the
1049 explicit implementations, so they get resolved/defined first.
1051 2002-06-21 Miguel de Icaza <miguel@ximian.com>
1053 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
1054 interface type is implemented by this TypeContainer. Used during
1055 explicit interface implementation.
1057 (Property.Define, Indexer.Define, Method.Define): Validate that
1058 the given interface in the explicit implementation is one of the
1059 base classes for the containing type.
1061 Also if we are explicitly implementing an interface, but there is
1062 no match in the pending implementation table, report an error.
1064 (Property.Define): Only define the property if we are
1065 not explicitly implementing a property from an interface. Use the
1066 correct name also for those properties (the same CSC uses,
1067 although that is really not needed).
1069 (Property.Emit): Do not emit attributes for explicitly implemented
1070 properties, as there is no TypeBuilder.
1072 (Indexer.Emit): ditto.
1074 Hiding then means that we do not really *implement* a pending
1075 implementation, which makes code fail.
1077 2002-06-22 Martin Baulig <martin@gnome.org>
1079 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
1080 the return value of Object.GetType(). [FIXME: we need to do this whenever
1081 we get a type back from the reflection library].
1083 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
1085 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
1087 2002-06-20 Miguel de Icaza <miguel@ximian.com>
1089 * attribute.cs: Return null if we can not look up the type.
1091 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
1092 the interface types found.
1094 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
1095 interface types found.
1097 * typemanager.cs (GetInterfaces): Make this routine returns alll
1098 the interfaces and work around the lame differences between
1099 System.Type and System.Reflection.Emit.TypeBuilder in the results
1100 result for GetInterfaces.
1102 (ExpandInterfaces): Given an array of interface types, expand and
1103 eliminate repeated ocurrences of an interface. This expands in
1104 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
1107 2002-06-21 Martin Baulig <martin@gnome.org>
1109 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
1112 2002-06-21 Martin Baulig <martin@gnome.org>
1114 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
1115 and called with one of the core types, return the corresponding typebuilder for
1118 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
1121 2002-06-21 Martin Baulig <martin@gnome.org>
1123 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
1124 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
1125 (Expression.ConvertReferenceExplicit): Likewise.
1127 * expression.cs (ElementAccess.DoResolve): Likewise.
1128 (ElementAccess.DoResolveLValue): Likewise.
1130 2002-06-10 Martin Baulig <martin@gnome.org>
1132 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
1133 add the "value" parameter to the parameter list.
1135 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
1138 2002-06-19 Miguel de Icaza <miguel@ximian.com>
1140 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
1141 the argument to an int, uint, long or ulong, per the spec. Also
1142 catch negative constants in array creation.
1144 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
1146 * class.cs: do not allow the same interface to appear twice in
1147 the definition list.
1149 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
1151 * ecore.cs: don't use ldlen with System.Array.
1153 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
1155 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
1157 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
1159 * modifiers.cs: produce correct field attributes for protected
1160 internal. Easy fix so miguel can work on ther harder stuff:-)
1162 2002-06-18 Miguel de Icaza <miguel@ximian.com>
1164 * pending.cs: New file. Move the code from class.cs here.
1165 Support clearning the pending flag for all methods (when not doing
1166 explicit interface implementation).
1168 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
1170 * rootcontext.cs: added a couple more types needed to bootstrap.
1172 2002-06-17 Miguel de Icaza <miguel@ximian.com>
1174 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
1175 constructor in the type, instead of any constructor in the type
1176 hierarchy. Thanks to Paolo for finding this bug (it showed up as
1177 a bug in the Mono runtime when applying the params attribute).
1179 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1180 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
1182 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
1184 * expression.cs (Unary.ResolveOperator): Use TypeManager
1185 to resolve the type.
1187 2002-06-13 Ravi Pratap <ravi@ximian.com>
1189 * cs-parser.jay (enum_member_declaration): Pass in the attributes
1192 * enum.cs (AddEnumMember): Add support to store the attributes associated
1193 with each member too.
1195 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
1196 field builders too - this takes care of the enum member case.
1198 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
1200 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
1201 address-of operator on both value types and pointers.
1203 2002-06-10 Martin Baulig <martin@gnome.org>
1205 * interface.cs (Interface.PopulateIndexer): Add the indexer's
1206 PropertyBuilder to the `property_builders' list.
1208 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
1209 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
1210 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
1211 find any indexers which are inherited from an interface.
1213 2002-06-09 Martin Baulig <martin@gnome.org>
1215 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
1216 the same type as the constant if necessary. There's also a test-130.cs
1219 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
1221 * typemanager.cs (TypeManager.ChangeType): Previously known as
1222 Enum.ChangeEnumType().
1224 2002-06-09 Martin Baulig <martin@gnome.org>
1226 * expression.cs (Cast.TryReduce): Added support for consts.
1228 2002-06-08 Ravi Pratap <ravi@ximian.com>
1230 * class.cs (Accessor): Hold attributes information so we can pass
1233 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
1234 Modify to pass in attributes attached to the methods.
1236 (add_accessor_declaration, remove_accessor_declaration): Ditto.
1238 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
1239 to handle the Accessor kind :-)
1241 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
1243 2002-06-08 Martin Baulig <martin@gnome.org>
1245 * expression.cs (Unary.TryReduceNegative): Added support for
1248 2002-06-08 Martin Baulig <martin@gnome.org>
1250 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
1251 name can't be found in the `defined_names' - the caller will do a
1252 MemberLookup in this case and thus find methods in System.Enum
1253 such as Enum.IsDefined().
1255 2002-06-08 Martin Baulig <martin@gnome.org>
1257 * enum.cs (Enum.ChangeEnumType): This is a custom version of
1258 Convert.ChangeType() which works with TypeBuilder created types.
1259 (Enum.LookupEnumValue, Enum.Define): Use it here.
1261 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
1262 `TypeBuilder.BaseType != null' check.
1263 (TypeContainer.FindMembers): Only lookup parent members if we
1264 actually have a parent.
1265 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
1266 (ConstructorInitializer.Resolve): Likewise.
1268 * interface.cs (Interface.FindMembers): Added
1269 `TypeBuilder.BaseType != null' check.
1271 * rootcontext.cs (RootContext.ResolveCore): Added
1272 "System.Runtime.CompilerServices.IndexerNameAttribute" to
1273 classes_second_stage.
1275 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
1276 debug_type and trace_type when compiling with --nostdlib.
1278 2002-06-07 Martin Baulig <martin@gnome.org>
1280 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
1281 (AddField): Set it to true when adding a non-static field.
1282 (DefineType): Use `have_nonstatic_fields' to find out whether we
1283 have non-static fields, not `Fields != null'.
1285 2002-06-02 Miguel de Icaza <miguel@ximian.com>
1287 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
1288 dereferencing a null on the static-field code path)
1290 2002-05-30 Martin Baulig <martin@gnome.org>
1292 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
1293 to take command line arguments. Use reflection to call the new
1294 custom `Initialize' function on the symbol writer and pass it the
1295 command line arguments.
1297 * driver.cs (--debug-args): New command line argument to pass command
1298 line arguments to the symbol writer.
1300 2002-05-28 Miguel de Icaza <miguel@ximian.com>
1302 * assign.cs (DoResolve): Forgot to do the implicit conversion to
1303 the target type for indexers and properties. Thanks to Joe for
1306 2002-05-27 Miguel de Icaza <miguel@ximian.com>
1308 * typemanager.cs (MethodFlags): returns the method flags
1309 (Obsolete/ShouldIgnore) that control warning emission and whether
1310 the invocation should be made, or ignored.
1312 * expression.cs (Invocation.Emit): Remove previous hack, we should
1313 not do this on matching a base type, we should do this based on an attribute
1315 Only emit calls to System.Diagnostics.Debug and
1316 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
1317 on the command line.
1319 * rootcontext.cs: Global settings for tracing and debugging.
1321 * cs-tokenizer.cs (define): New utility function to track
1322 defines. Set the global settings for TRACE and DEBUG if found.
1324 2002-05-25 Ravi Pratap <ravi@ximian.com>
1326 * interface.cs (Populate*): Pass in the TypeContainer as well as
1327 the DeclSpace as parameters so that we can create EmitContexts and
1328 then use that to apply attributes etc.
1330 (PopulateMethod, PopulateEvent, PopulateProperty)
1331 (PopulateIndexer): Apply attributes everywhere.
1333 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
1336 (ApplyAttributes): Update accordingly.
1338 We now apply interface attributes for all members too.
1340 2002-05-26 Miguel de Icaza <miguel@ximian.com>
1342 * class.cs (Indexer.Define); Correctly check if we are explicit
1343 implementation (instead of checking the Name for a ".", we
1344 directly look up if the InterfaceType was specified).
1346 Delay the creation of the PropertyBuilder.
1348 Only create the PropertyBuilder if we are not an explicit
1349 interface implementation. This means that explicit interface
1350 implementation members do not participate in regular function
1351 lookups, and hence fixes another major ambiguity problem in
1352 overload resolution (that was the visible effect).
1354 (DefineMethod): Return whether we are doing an interface
1357 * typemanager.cs: Temporary hack until we get attributes in
1358 interfaces (Ravi is working on that) and we get IndexerName
1359 support in interfaces.
1361 * interface.cs: Register the indexers as properties.
1363 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
1364 warning, I have verified that this is a bug in the .NET runtime
1365 (JavaScript suffers of the same problem).
1367 * typemanager.cs (MemberLookup): When looking up members for
1368 interfaces, the parent of an interface is the implicit
1369 System.Object (so we succeed in searches of Object methods in an
1370 interface method invocation. Example: IEnumerable x; x.ToString
1373 2002-05-25 Miguel de Icaza <miguel@ximian.com>
1375 * class.cs (Event): Events should also register if they do
1376 implement the methods that an interface requires.
1378 * typemanager.cs (MemberLookup); use the new GetInterfaces
1381 (GetInterfaces): The code used to lookup interfaces for a type is
1382 used in more than one place, factor it here.
1384 * driver.cs: Track the errors at the bottom of the file, we kept
1387 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
1388 instance if the method we are calling is static!
1390 2002-05-24 Miguel de Icaza <miguel@ximian.com>
1392 * attribute.cs (ApplyAttributes): Make this function filter out
1393 the IndexerName attribute (as that attribute in reality is never
1394 applied) and return the string constant for the IndexerName
1397 * class.cs (TypeContainer.Emit): Validate that all the indexers
1398 have the same IndexerName attribute, and if so, set the
1399 DefaultName attribute on the class.
1401 * typemanager.cs: The return value might contain other stuff (not
1402 only methods). For instance, consider a method with an "Item"
1403 property and an Item method.
1405 * class.cs: If there is a problem with the parameter types,
1408 2002-05-24 Ravi Pratap <ravi@ximian.com>
1410 * ecore.cs (ImplicitConversionExists): Wrapper function which also
1411 looks at user defined conversion after making a call to
1412 StandardConversionExists - we need this for overload resolution.
1414 * expression.cs : Update accordingly the various method calls.
1416 This fixes 2 bugs filed against implicit user defined conversions
1418 2002-05-22 Miguel de Icaza <miguel@ximian.com>
1420 * statement.cs: Track the result of the assignment.
1422 2002-05-21 Miguel de Icaza <miguel@ximian.com>
1424 * expression.cs (MemberAccess): Improved error reporting for
1425 inaccessible members.
1427 2002-05-22 Martin Baulig <martin@gnome.org>
1429 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
1430 itself with debugging support.
1432 2002-05-22 Martin Baulig <martin@gnome.org>
1434 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
1435 Removed, this isn't needed anymore.
1437 2002-05-20 Martin Baulig <martin@gnome.org>
1439 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
1440 be underlying type for an enum.
1442 2002-05-20 Miguel de Icaza <miguel@ximian.com>
1444 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
1445 that splits out the loading of just the core types.
1447 * rootcontext.cs (ResolveCore): Split the struct resolution in
1448 two, so we can load the enumeration underlying types before any
1451 * expression.cs (Is): Bandaid until we fix properly Switch (see
1452 bug #24985 for details).
1454 * typemanager.cs (ImplementsInterface): The hashtable will contain
1455 a null if there are no interfaces implemented.
1457 2002-05-18 Miguel de Icaza <miguel@ximian.com>
1459 * cs-parser.jay (indexer_declarator): It is fine to have array
1462 2002-05-17 Miguel de Icaza <miguel@ximian.com>
1464 * typemanager.cs: (RegisterBuilder): New function used to register
1465 TypeBuilders that implement interfaces. Since
1466 TypeBuilder.GetInterfaces (as usual) does not work with lame
1468 (AddUserType): register interfaces.
1470 (ImplementsInterface): Use the builder_to_ifaces hash if we are
1471 dealing with TypeBuilder. Also, arrays are showing up as
1472 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
1473 methods can not be invoked on them!
1475 * ecore.cs (ExplicitReferenceConversionExists): Made public.
1476 (ImplicitReferenceConversionExists): Split out from
1477 StandardConversionExists.
1479 * expression.cs (As): We were only implementing one of the three
1480 cases for the as operator. We now implement them all.
1481 (Is): Implement the various other cases for Is as well.
1483 * typemanager.cs (CACHE): New define used to control if we want or
1484 not the FindMembers cache. Seems to have a negative impact on
1485 performance currently
1487 (MemberLookup): Nested types have full acess to
1488 enclosing type members
1490 Remove code that coped with instance/static returns for events, we
1491 now catch this in RealFindMembers.
1493 (RealFindMembers): only perform static lookup if the instance
1494 lookup did not return a type or an event.
1496 2002-05-17 Miguel de Icaza <miguel@ximian.com>
1498 * assign.cs (CompoundAssign): We pass more semantic information
1499 now to Compound Assignments than we did before: now we have all
1500 the information at hand, and now we resolve the target *before* we
1501 do the expression expansion, which allows the "CacheValue" method
1502 to have the effect we intended (before, a [x] += 1 would generate
1503 two differen ArrayAccess expressions from the ElementAccess,
1504 during the resolution process).
1506 (CompoundAssign.DoResolve): Resolve target and original_source here.
1508 2002-05-16 Miguel de Icaza <miguel@ximian.com>
1510 * expression.cs (ArrayAccess): dropped debugging information.
1512 * typemanager.cs: Small bug fix: I was always returning i_members,
1513 instead of one of i_members or s_members (depending on which had
1516 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
1517 method is invoked before any code generation takes place, and it
1518 is a mechanism to inform that the expression will be invoked more
1519 than once, and that the method should use temporary values to
1520 avoid having side effects
1522 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
1524 * ecore.cs (Expression.CacheTemporaries): Provide empty default
1527 * expression.cs (Indirection, ArrayAccess): Add support for
1528 CacheTemporaries in these two bad boys.
1530 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
1532 (StoreFromPtr): Handle stobj as well.
1534 * expression.cs (UnaryMutator): Share more code.
1536 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
1537 down: I was not tracking the Filter function as well, which
1538 was affecting the results of the cache.
1540 2002-05-15 Miguel de Icaza <miguel@ximian.com>
1542 * attribute.cs: Remove the hack to handle the CharSet property on
1545 2002-05-14 Miguel de Icaza <miguel@ximian.com>
1547 * attribute.cs (DoResolve): More uglyness, we now only try to
1548 resolve the attribute partially, to extract the CharSet
1549 information (only if we are a StructLayout attribute). Otherwise
1551 (GetExtraTypeInfo): Add some code to conditionally kill in the
1552 future this. I am more and more convinced that the .NET
1553 framework has special code to handle the attribute setting on
1556 * expression.cs (IsParamsMethodApplicable): Revert my previous
1557 foreach change here, it was wrong.
1559 2002-05-13 Miguel de Icaza <miguel@ximian.com>
1561 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
1562 (pp_expr): do not abort on unknown input, just return.
1563 (eval): abort if there are pending chars.
1565 * attribute.cs (Attribute.Resolve): Positional parameters are
1566 optional. Deal with that case.
1568 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
1569 the Ansi/Unicode/Auto information for the type.
1571 (TypeContainer.DefineType): instantiate the EmitContext here, as
1572 we will be using it during the type definition (to resolve
1573 attributes) and during the emit phase.
1575 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
1576 to pull type information out of the attributes
1578 (Attribute.Resolve): track the constructor builder, and allow for
1579 multiple invocations (structs and classes will use this).
1581 * ecore.cs (MemberLookupFinal): new version with all the
1582 parameters customizable.
1584 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
1585 constructors. Return if the result value is null (as the error
1586 would have been flagged already by MemberLookupFinal)
1588 Do not allow instances of abstract classes or interfaces to be
1591 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
1592 We have to compare the assembly property here when dealing with
1593 FamANDAssem and Assembly access modifiers, because we might be
1594 creating an assembly from *modules* (that means that we are not
1595 getting TypeBuilders for types defined in other modules that are
1596 part of this assembly).
1598 (Method.Emit): If the method is marked abstract and has a body,
1601 (TypeContainer.DefineMembers): If both the defined member and the
1602 parent name match are methods, then do not emit any warnings: let
1603 the Method.Define routine take care of flagging warnings. But if
1604 there is a mismatch (method overrides something else, or method is
1605 overriwritten by something, then emit warning).
1607 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
1608 set to null, this means `do not check for the return type on the
1611 (Method.Define): set the return type for the method signature to
1612 null, so that we get methods with the same name and parameters and
1613 different return types. This is used to flag warning 114 (you are
1614 hiding a method, and you probably want to use the new/override
1617 * typemanager.cs (MemberLookup): Implemented proper access
1618 control, closing a long standing set of bug reports. The problem
1619 was that the Framework only has two bits: Public and NonPublic,
1620 and NonPublic includes private and protected methods, but we need
1621 to enforce the FamANDAssem, FamOrAssem and Family.
1623 2002-05-11 Miguel de Icaza <miguel@ximian.com>
1625 * statement.cs (GotoCase): Return true: Ammounts to giving up
1626 knowledge on whether we return or not, and letting the other case
1627 be responsible for it.
1629 2002-05-10 Miguel de Icaza <miguel@ximian.com>
1631 * driver.cs: Do not load directories for each file processed, only
1632 do it if there is a pattern.
1634 * ecore.cs: Report readonly assigns here as well, as we might have
1635 been resolved only by MemberAccess.
1637 (SimpleName.SimpleNameResolve): Also be useful for LValue
1638 resolution. We need this to propagate assign to local readonly variables
1640 * typemanager.cs: Use a ptrhashtable for the criteria, because we
1641 do not want to reuse potential criteria memory.
1643 * class.cs (MyEventBuilder): Set reflected_type;
1645 * ecore.cs (Constantify): Added support for constifying bools.
1647 (RootContext.LookupType): Added a cache for values looked up in
1648 the declaration space.
1650 * typemanager.cs (FindMembers): Now is a front-end to
1651 RealFindMembers, and provides a two-level hashtable-based cache to
1654 15% performance improvement: from 22.5 to 19.2 seconds.
1656 * expression.cs (IsParamsMethodApplicable): use foreach.
1657 (Invocation.DoResolve): ditto.
1658 (New.DoResolve): ditto.
1659 (ArrayCreation.DoResolve): ditto.
1661 * ecore.cs (FindMostEncompassingType): use foreach.
1663 * delegate.cs (NewDelegate.DoResolve): Use foreach
1665 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
1666 (RemoveMethods): use foreach.
1668 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
1669 nested foreach statements instead of for, and also break out of
1670 the inner loop once a match is found.
1672 (Invocation.OverloadResolve): Use foreach, simplify the code.
1674 2002-05-08 Miguel de Icaza <miguel@ximian.com>
1676 * cfold.cs (BinaryFold): During an enumeration evaluation context,
1677 we actually unwrap the expression to allow for extra information
1680 * expression.cs: Use Shr_Un on unsigned operations.
1682 2002-05-08 Ravi Pratap <ravi@ximian.com>
1684 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
1685 applicable operators was not being considered correctly. This closes
1686 the bug Miguel reported.
1688 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
1690 * attribute.cs: check that the type derives from System.Attribute
1691 and report the correct error in that case (moved the duplicate code to
1692 its own method, too).
1694 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
1696 * attribute.cs: lookup attribute type name as the spec says: first the
1697 bare attribute name and then name + "Attribute" (nant compiles with
1698 mcs after this fix).
1700 2002-05-07 Miguel de Icaza <miguel@ximian.com>
1702 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
1703 Because of the way we parse things, we should try to see if a
1704 UIntConstant can fit in an integer.
1706 2002-05-07 Ravi Pratap <ravi@ximian.com>
1708 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
1709 when we are in an explicit context.
1711 (ConvertReferenceExplicit): When converting from Iface type S to Class
1712 T make sure the rules are implemented as an OR.
1714 * parameter.cs (ParameterType): Make it a property for now although the
1715 purpose really isn't anything immediate.
1717 * expression.cs (Is*Applicable): Do better checking on the parameter type
1718 of a ref/out parameter. The ones from the system assemblies are already
1719 marked with the correct type so we don't need to do any correction.
1721 * ecore.cs (StandardConversionExists): Conversion from Interface types to
1722 the object type is standard too so include that.
1724 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1726 * ecore.cs (StandardConversionExists): Augment with missing code:
1727 deal with IntConstant, LongConstants and Enumerations.
1729 * assign.cs: Report the error, instead of failing silently
1731 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
1732 typecontainer that they are declared, because the
1733 typecontainer/namespace will have the list of using clauses that
1736 Assembly Attributes were escaping the normal registration
1739 (EmitCode): Apply attributes within an EmitContext that represents
1740 the container they were declared on.
1742 * cs-parser.jay: Track bases for structs. How did I get this wrong?
1744 2002-05-06 Ravi Pratap <ravi@ximian.com>
1746 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
1747 Revamp completely - make much cleaner as we now operate only
1750 (FindMostSpecificSource, FindMostSpecificTarget): New methods
1751 to implement the logic detailed in the spec more correctly.
1753 (UserDefinedConversion): Update accordingly.
1755 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1757 * statement.cs: Return flow analysis information up.
1759 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
1762 (token): Do not consume an extra character before calling
1765 2002-05-06 Piers Haken <piersh@friskit.com>
1767 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
1769 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1771 * class.cs (Constructor.Emit): Set the IsStatic flag in the
1772 EmitContext during the instance constructor initializer
1773 resolution, to stop access to instance variables.
1775 This is mandated by the spec, last paragraph of the `constructor
1776 initializers' section.
1778 2002-05-05 Miguel de Icaza <miguel@ximian.com>
1780 * cs-parser.jay, class.cs (Accessor): new class used to represent
1781 an accessor (get or set). In the past we used `null' to represent
1782 a missing accessor. But this is ambiguous because there was no
1783 way to tell in abstract indexers/properties if one of them was
1786 Now there is a way of addressing that.
1788 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
1789 instead of FindMembers.
1791 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
1792 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
1794 * attribute.cs: Treat indexers and properties as the same in terms
1795 of applying attributes
1797 * ecore.cs (FindMostEncompassedType): Use statically initialized
1798 EmptyExpressions()s like we do elsewhere to avoid creating useless
1799 objects (and we take this out of the tight loop).
1801 (GetConversionOperators): Move the code to extract the actual
1802 operators to a separate routine to clean things up.
1804 2002-05-04 Miguel de Icaza <miguel@ximian.com>
1806 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
1807 events are always registered FieldBuilders.
1809 * class.cs (FieldBase): New class shared by Fields
1811 * delegate.cs: If we are a toplevel delegate, use our full name.
1812 If we are a nested delegate, then only use our tail name.
1814 2002-05-02 Ravi Pratap <ravi@ximian.com>
1816 * expression.cs (IsApplicable): Ensure that we add the "&" to
1817 ref/out types before comparing it with the type of the argument.
1819 (IsParamsMethodApplicable): Ditto.
1821 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
1824 * delegate.cs : Handle the case when we have more than one applicable
1825 method. Flag an error only when we finish checking all.
1827 2002-05-02 Miguel de Icaza <miguel@ximian.com>
1829 * expression.cs: Add support for boolean static initializers.
1831 2002-05-01 Miguel de Icaza <miguel@ximian.com>
1833 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
1835 * parameter.cs (ComputeParameterTypes,
1836 ComputeAndDefineParameterTypes): Better error handling: now we
1837 clear the `types' cache if we fail during any of the type lookups.
1838 We also return the status code correctly to our caller
1840 * delegate.cs: If we fail to define a delegate, abort the extra
1843 * expression.cs (Binary.ResolveOperator): for
1844 operator==(object,object) and operator !=(object, object) we also
1845 have to verify that there is an implicit conversion from one to
1848 (ArrayAccess.DoResolve): Array Access can operate on
1851 2002-04-30 Miguel de Icaza <miguel@ximian.com>
1853 * assign.cs (CompoundAssign): A new class used as a "flag" that
1854 the assignment actually is happening as part of a compound
1855 assignment operator.
1857 During compound assignment, a few new rules exist to enable things
1864 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
1865 to the type of x) if y is implicitly convertible to the type of x,
1866 and the operator is a builtin operator and the return type of the
1867 operator is explicitly convertible to the type of x.
1869 * rootcontext.cs: Reset warning level to 2. 4 catches various
1870 "interesting" features in mcs, we must clean this up at some
1871 point, but currently am trying to kill other bugs ;-)
1873 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
1874 in container classes as well.
1876 * expression.cs (Binary.ResolveOperator): Handle string case
1877 before anything else (as operator overloading does emit an error
1878 before doing anything else).
1880 This code could go away when we move to a table driven model, but
1881 i could not come up with a good plan last night.
1883 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
1885 * typemanager.cs (CSharpName): reimplementation using regex.
1886 * class.cs: added null check for fields in Emit
1887 * rootcontext.cs: set warninglevel to 4
1889 2002-04-29 Miguel de Icaza <miguel@ximian.com>
1891 * typemanager.cs (CSharpName): reimplemented with Lupus
1894 2002-04-28 Miguel de Icaza <miguel@ximian.com>
1896 * statement.cs (If): correclty implement Resolve, because we were
1897 not catching sem errors in there. The same process is needed
1899 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
1902 (Statement.Warning_DeadCodeFound): Factorize code.
1903 (While): Report dead code here too.
1905 (Statement): Added Resolve virtual method to allow
1906 for resolution split from the emit code.
1908 2002-04-26 Miguel de Icaza <miguel@ximian.com>
1910 * statement.cs (EmitBoolExpression): No longer try to resolve the
1912 (MakeBoolean): New utility function that resolve, implicitly
1913 converts to boolean and tags the expression.
1916 (If, Do): Implement dead code elimination.
1917 (While): Implement loop inversion
1919 (Do, While, For, If): Resolve the expression prior to calling our
1922 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
1925 - added method Report28 (warning: program has more than one entry point)
1926 - added method IsEntryPoint, implements paragraph 10.1 of the spec
1927 - modified method Method.Define, the part at the end of the method
1929 * rootcontext.cs: added static public Location EntryPointLocation;
1931 * ../errors/cs0028.cs : Add test case for the above warning.
1934 - modified method CSharpName to allow arrays of primitive type to
1935 be printed nicely (e.g. instead of System.Int32[][] it now prints
1937 - added method CSharpSignature: returns the signature of a method
1938 in string format to be used in reporting errors, warnings, etc.
1940 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
1943 2002-04-26 Ravi Pratap <ravi@ximian.com>
1945 * delegate.cs (Define): Fix extremely silly bug where I was
1946 setting the type of the 'object' parameter of the BeginInvoke
1947 method to System.IAsyncResult instead of System.Object ;-)
1949 2002-04-26 Miguel de Icaza <miguel@ximian.com>
1951 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
1954 (Constructor.Emit): return if we fail to initialize the
1955 constructor. Another door closed!
1957 * expression.cs (New.DoResolve): Improve error message (from -6 to
1958 1501). Use DeclaredOnly lookup to find the exact constructor.
1960 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
1961 loop. This is useful.
1963 * cs-parser.jay: Adjust the default parameters so that destructors
1964 have the proper signature.
1966 2002-04-26 Martin Baulig <martin@gnome.org>
1968 * driver.cs (LoadAssembly): If `assembly' contains any characters
1969 which are only valid in path names and not in assembly names
1970 (currently slash, backslash and point), use Assembly.LoadFrom ()
1971 instead of Assembly.Load () on the `assembly' (before iteration
1972 over the link_paths).
1974 2002-04-26 Martin Baulig <martin@gnome.org>
1976 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
1978 2002-04-25 Miguel de Icaza <miguel@ximian.com>
1980 * class.cs (Property): use the new typemanager.MemberLookup
1982 (TypeContainer.MemberLookup): Implement using the
1983 TypeManager.MemberLookup now.
1985 * typemanager.cs: Make MemberLookup a function of the TypeManager,
1986 and return MemberInfos, so that these can be used without an
1987 EmitContext (what we had before).
1989 2002-04-24 Miguel de Icaza <miguel@ximian.com>
1991 * expression.cs: Fix the case where the argument to params if the
1992 type of the params. I omitted handling this before. Fixed
1994 2002-04-22 Miguel de Icaza <miguel@ximian.com>
1996 * driver.cs: Call BootCorlib_PopulateCoreType
1998 * class.cs (Property.CheckBase): Check for properties only, not
2001 * interface.cs: Temporary hack: try/catch around the
2002 CustomAttributeBuilder, because I am getting an exception that I
2005 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
2006 types whose definitions are required to be there (attributes are
2007 defined before standard types).
2009 Compute definitions as we boot the various types, as they are used
2010 immediately (value_type class will need object_type, but if we do
2011 not initialize object_type, we will pass a null, which will let
2012 the runtime pick the System.Object from the existing corlib, which
2013 is not what we want).
2015 2002-04-22 Patrik Torstensson <totte@labs2.com>
2017 * cs-tokenizer.cs: fixed a number of trim() issues.
2019 2002-04-22 Ravi Pratap <ravi@ximian.com>
2021 * expression.cs (Argument.Type): Ensure that we return the correct
2022 type when we have out or ref parameters [in which case we
2025 2002-04-22 Miguel de Icaza <miguel@ximian.com>
2027 * class.cs (Property, Indexer): Allow extern modifier in there.
2029 * typemanager.cs (InitBaseTypes): Initializes object_type and
2030 value_type, since those will be used early on during the bootstrap
2031 process to compile corlib.
2033 (InitCoreTypes): Move code from here to InitBaseTypes.
2035 2002-04-21 Miguel de Icaza <miguel@ximian.com>
2037 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
2038 single-dimension arrays as using the ldlen opcode.
2040 Daniel Lewis discovered this optimization.
2042 * typemanager.cs: Add signature for System.Array::get_Length
2044 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2046 * statement.cs: report the error when the foreach does not apply to an
2047 array nor a collection.
2049 2002-04-19 Miguel de Icaza <miguel@ximian.com>
2051 * expression.cs: Add implicit conversions to the operator ~.
2053 * constant.cs (DecimalConstant.Emit): Emit decimal value.
2055 * typemanager.cs: Locate the decimal constructor.
2057 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2059 * attribute.cs: use the new property of TypeOf.
2060 * expression.cs: added 'get' property around typearg.
2062 These changes fix a build breaker reported by NickD. Is this the
2063 correct way to fix? If not, please, revert my changes and make it
2066 2002-04-17 Miguel de Icaza <miguel@ximian.com>
2068 * attribute.cs: Add support for typeof in attribute invocations.
2069 I am not sure that this is right though.
2071 2002-04-14 Duncan Mak <duncan@ximian.com>
2073 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
2074 Binary.Operator.Division case.
2076 2002-04-13 Ravi Pratap <ravi@ximian.com>
2078 * class.cs (DefineType): Ensure that we do a proper check on
2079 attribute types and also register it with the TypeManager.
2081 (TypeContainer.Targets): The default for attribute types is
2082 AttributeTargets.All.
2084 * attribute.cs (ApplyAttributes): Registering the attribute type
2085 is done elsewhere, not when we discover we have a Usage attribute.
2087 2002-04-12 Ravi Pratap <ravi@ximian.com>
2089 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
2090 and get rid of is_delegate parameter.
2092 * everywhere : update.
2094 2002-04-12 Ravi Pratap <ravi@ximian.com>
2096 * cs-parser.jay (compilation_unit): Revamp completely to use
2097 some new ideas that I got from Rhys' grammar to solve the problems
2098 with assembly level attributes.
2100 (outer_declaration): New grammar production.
2102 (attribute_sections): Add.
2104 (opt_attributes): Base on attribute_sections
2106 (namespace_declaration): Allow opt_attributes to tackle the case
2107 when we have assembly level attributes - we are clever in this
2110 * attribute.cs (ApplyAttributes): Do not worry about assembly
2111 attributes in the non-global context.
2113 * rootcontext.cs (AddGlobalAttributes): Go back to using this
2114 instead of SetGlobalAttributes.
2116 * class.cs, rootcontext.cs : Ensure we define and generate
2117 attribute types before anything else.
2119 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
2120 and flag the new error -20 for the case when the attribute type
2121 does not have valid targets specified. csc does not catch this.
2123 * ../errors/errors.txt : update for error # -20
2125 2002-04-11 Ravi Pratap <ravi@ximian.com>
2127 * support.cs (InternalParameters.ParameterModifier): Do some null
2128 checking and return sane values.
2130 * class.cs (Method.Define): If we are a PInvoke method, ensure
2131 that we are static and extern. Report error # 601
2133 * ../errors/cs0601.cs : Add test case for the above error.
2135 2002-04-07 Ravi Pratap <ravi@ximian.com>
2137 * rootcontext.cs (attribute_types): We need to keep type of
2138 all attribute types separately and emit code for them first.
2140 (RegisterAttribute) : Implement.
2142 * class.cs (DefineType): Check if the current Type is a custom
2143 attribute type and register it accordingly.
2145 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
2146 adding the first attribute twice and rename to
2148 (SetGlobalAttributes): this.
2150 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
2153 * attribute.cs (ApplyAttributes): Take an additional argument telling us
2154 if we are processing global arguments. Hmm, I am unsure of this.
2156 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2158 * expression.cs: added static array of strings to avoid calling
2159 Enum.ToString () for Operator in Binary. Significant recover of
2162 2002-04-10 Miguel de Icaza <miguel@ximian.com>
2164 * class.cs (FindMembers): Allow the Builders of the various
2165 members to be null. If they are skip them. This only happens
2166 during the PInvoke declaration.
2168 2002-04-09 Miguel de Icaza <miguel@ximian.com>
2170 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
2171 failure, so we do not keep going afterwards.
2173 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
2174 wanted to pass `false' as the `is_delegate' argument. If this is
2175 the case, why not use delegate_type == null to mean `is_delegate =
2176 false' and anything else as is_delegate = true.
2178 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
2180 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
2181 code for the section, not the beginning of the tests.
2183 2002-04-08 Miguel de Icaza <miguel@ximian.com>
2185 * cfold.cs: Handle operator + (Enum x, Underlying x)
2187 * expression.cs (Binary): same. Warn about errors where we have
2188 Enum/Enum in operator + as well.
2190 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
2193 - added support for switch(bool)
2194 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
2195 - add TableSwitchEmit() to handle table-based switch statements
2197 2002-04-05 Ravi Pratap <ravi@ximian.com>
2199 * expression.cs (Invocation.OverloadResolve): Factor out code which
2200 does parameter compatibility checking with arguments so that we can
2201 re-use the code even from Delegate.VerifyApplicability
2203 (VerifyArgumentsCompat): Move above code here.
2205 * delegate.cs (VerifyApplicability): Get rid of duplicate code
2206 and instead make a call to the above method.
2208 2002-03-31 Ravi Pratap <ravi@ximian.com>
2210 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
2211 We use it to keep track of classes which are attribute types.
2213 2002-04-02 Miguel de Icaza <miguel@ximian.com>
2215 * delegate.cs (Delegate.Define): Correctly define the types in the
2216 presence of fixed and array parameters.
2218 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
2221 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
2222 include NonPublic after the first iteration.
2224 * class.cs (Indexer.CheckBase): Only check if both parents are
2227 * cs-parser.jay (accessor_body): If empty, set to null.
2229 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
2230 same code path here to resolve constants names that we did have in
2231 MemberAccess.DoResolve. There is too much code duplicated here.
2233 2002-04-01 Miguel de Icaza <miguel@ximian.com>
2235 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
2237 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
2240 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
2241 tokens, numbers and strings.
2243 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
2246 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
2247 asyncronous parameters and the regular parameters.
2249 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
2250 specify the target directory.
2252 * expression.cs: (This.DoResolve): Simplify
2253 (As.Emit): Optimize, do not generate IsInst if the expression is
2254 always of the given type.
2256 (Is.DoResolve): Bug fix, we were reporting both always/never for
2259 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
2260 creating too many unnecessary arrays.
2262 2002-03-31 Miguel de Icaza <miguel@ximian.com>
2264 * class.cs (EmitFieldInitializer): Use Assign expression to assign
2265 fields instead of rolling our own initializer. Takes care of all
2266 implicit conversions, and drops unnecessary static checks/argument.
2268 2002-03-31 Dick Porter <dick@ximian.com>
2270 * driver.cs: use the GetDirectories() return values properly, and
2271 use "/" as path separator.
2273 2002-03-30 Miguel de Icaza <miguel@ximian.com>
2275 * expression.cs (Unary): Optimize - - expr into expr.
2276 (Binary): Optimize a + (-b) into a -b.
2278 * codegen.cs (CodeGen): Made all methods static.
2280 2002-03-29 Miguel de Icaza <miguel@ximian.com>
2284 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
2285 TypeBuilder property.
2287 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
2290 * tree.cs: Removed the various RecordXXXX, and replaced with a
2291 single RecordDecl. Removed all the accessor methods, and just
2292 left a single access point Type
2294 * enum.cs: Rename DefineEnum to DefineType.
2296 * decl.cs: New abstract method `DefineType' used to unify the
2297 Defines for Enumerations, Interfaces, TypeContainers and
2300 (FindType): Moved LookupInterfaceOrClass here. Moved the
2301 LookupBaseClasses method that used to live in class.cs and
2302 interface.cs here, and renamed to FindType.
2304 * delegate.cs: Implement DefineType. Take advantage of the
2305 refactored pattern for locating the parent builder without taking
2306 the parent_builder argument (which we know does not work if we are
2307 nested, and triggering a toplevel definition).
2309 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2311 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
2312 accessibility of a member has changed during override and report
2315 * class.cs (Method.Define, Property.Define): Only complain on
2316 overrides if the method is private, any other accessibility is
2317 fine (and since we just checked the permission is the same, we are
2320 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
2321 and elif are processed always. The other pre-processing
2322 directives are only processed if we are "taking" the path
2324 2002-03-29 Martin Baulig <martin@gnome.org>
2326 * class.cs (Method.Emit): Only emit symbolic debugging info if the
2327 current location is not Null.
2329 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
2330 a separate method so we can profile it.
2332 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
2333 `span.Seconds' are just seconds, but no minutes or hours.
2334 (MainDriver): Profile the CodeGen.SaveSymbols calls.
2336 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2338 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
2339 Remove the gratuitous set of Final:
2341 // If an interface implementation, then we can set Final.
2342 if (((flags & MethodAttributes.Abstract) == 0) &&
2343 implementing.DeclaringType.IsInterface)
2344 flags |= MethodAttributes.Final;
2346 I do not know what I was smoking when I used that.
2349 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
2350 step into fixing the name resolution issues for delegates and
2351 unifying the toplevel name resolution.
2353 2002-03-28 Martin Baulig <martin@gnome.org>
2355 * class.cs (Method.Emit): If we have a symbol writer, call its
2356 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
2357 tell it about the current method.
2359 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
2360 writer that we're going to emit the first byte of IL code for a new
2361 statement (a new source line).
2362 (EmitContext.EmitTopBlock): If we have a symbol writer, call
2363 EmitContext.Mark() before emitting any code.
2365 * location.cs (SymbolDocument): Return null when we're Null.
2367 * statement.cs (Statement): Moved the `Location loc' variable here.
2368 (Statement.EmitBoolExpression): If we have a symbol writer, call
2369 ec.Mark() before emitting any code to tell it that we're at the
2370 beginning of a new statement.
2371 (StatementExpression): Added `Location' argument to the constructor.
2372 (Block): Added public readonly variable `StartLocation' and public
2373 variable `EndLocation'. The latter is to be set using SetEndLocation().
2374 (Block): Added constructor which takes a start and end location.
2375 (Block.SetEndLocation): New method. This sets the end location.
2376 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
2377 local variables we create.
2378 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
2379 each statement and do also mark the begin and end of the block.
2381 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
2382 tell it the current lexer.Location, use Location.Null for the end of the
2384 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
2385 current block, set its end location using SetEndLocation().
2386 (statement_expression): StatementExpression constructor now takes the
2387 lexer.Location as additional argument.
2388 (for_statement, declare_local_variables): Likewise.
2389 (declare_local_variables): When creating a new implicit block, use the
2390 new Block constructor and pass it the lexer.Location.
2392 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2394 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
2395 members also on the parent interfaces recursively.
2397 2002-03-27 Miguel de Icaza <miguel@ximian.com>
2399 * report.cs: Use new formats, since Gonzalo finished the missing
2402 * expression.cs (Binary.ResolveOperator): added missing operator|
2403 operator& and operator^ for bool/bool.
2405 * cs-parser.jay: CheckDef now takes a Location argument that is
2406 used to report errors more precisly (instead of reporting the end
2407 of a definition, we try to track something which is a lot closer
2408 to the source of the problem).
2410 * cs-tokenizer.cs: Track global token use, so we can properly flag
2411 the use of #define/#undef after the first token has been seen.
2413 Also, rename the reportXXXX to Error_DescriptiveName
2415 * decl.cs (DeclSpace.IsTopLevel): Move property here from
2416 TypeContainer, so that Enum and Interface can use this too.
2418 * class.cs (TypeContainer.LookupInterfaceOrClass,
2419 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
2420 `builder' argument. Typically this was used to pass the parent
2421 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
2424 The problem is that a nested class could trigger the definition of
2425 a toplevel class, and the builder would be obviously wrong in that
2428 So we drop this argument, and we compute dynamically the
2429 TypeBuilder/ModuleBuilder (the correct information was available
2430 to us anyways from DeclSpace.Parent)
2432 * interface.cs (Interface.DefineInterface): Drop builder
2433 parameter cleanup like class.cs
2435 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
2438 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
2441 (Try.Emit): Propagate the returns value from the statement.
2443 (Return.Emit): Even if we are leavning
2445 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
2447 * modifiers.cs: Fix the computation of MethodAttributes flags.
2449 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
2451 * driver.cs: allow compilation of files that start with '/'.
2452 Add a default case when checking the argument of --target.
2454 2002-03-25 Miguel de Icaza <miguel@ximian.com>
2456 * interface.cs: Implement the same search algorithm for types in
2459 * delegate.cs: Do not allow multiple definition.
2461 * Recovered ChangeLog that got accidentally amputated
2463 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
2465 * rootcontext.cs: Load manually enum to allow core classes to
2466 contain enumerations.
2468 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
2469 Update to new static methods in TypeManager.
2471 * typemanager.cs (GetMethod, GetConstructor): Use our
2472 implementation of FindMembers to find the members, since during
2473 corlib compilation, the types are TypeBuilders and GetMethod and
2474 GetConstructor do not work.
2476 Make all methods in TypeManager static.
2478 (InitCodeHelpers): Split the functionality from
2479 the InitCodeTypes function.
2481 * driver.cs: Call InitCodeHelpers after we have populated the
2484 * cs-parser.jay (delegate_declaration): we did not used to compute
2485 the delegate name correctly for void delegates.
2487 2002-03-24 Miguel de Icaza <miguel@ximian.com>
2489 * rootcontext.cs (RootContext): Init the interface_resolve_order
2490 and type_container_resolve_order always.
2492 (ResolveCore, BootstrapCorlib_ResolveClass,
2493 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
2494 compiler when compiling with --nostdlib
2496 * class.cs (TypeContainer.DefineType): Check that our parent is
2497 not null. This test is most important when we are bootstraping
2500 * codegen.cs: Split out the symbol writing code.
2502 2002-03-25 Martin Baulig <martin@gnome.org>
2504 * driver.cs (-g): Made -g an alias for --debug.
2506 2002-03-24 Martin Baulig <martin@gnome.org>
2508 * codegen.cs (SymbolWriter): New public variable. Returns the
2509 current symbol writer.
2510 (CodeGen): Added `bool want_debugging_support' argument to the
2511 constructor. If true, tell the ModuleBuild that we want debugging
2512 support and ask it for the ISymbolWriter.
2513 (Save): If we have a symbol writer, call it's Close() method after
2514 saving the assembly.
2516 * driver.c (--debug): New command line argument to create a
2517 debugger information file.
2519 * location.cs (SymbolDocument): New public property. Returns an
2520 ISymbolDocumentWriter object for the current source file or null
2521 if we don't have a symbol writer.
2523 2002-03-21 Miguel de Icaza <miguel@ximian.com>
2525 * driver.cs (LoadAssembly): Correctly return when all the paths
2526 have been tried and not before.
2528 * statement.cs (Switch.Emit): return the actual coverage for this
2529 statement (returns/not-returns)
2531 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
2532 switch of the statement if we are the last switch section. That
2533 kills two problems: try/catch problems (we used to emit an empty
2534 nop at the end) and switch statements where all branches would
2537 2002-03-19 Miguel de Icaza <miguel@ximian.com>
2539 * driver.cs: Add default assemblies (the equivalent to the
2540 Microsoft CSC.RSP file)
2542 * cs-tokenizer.cs: When updating `cols and setting it to zero,
2543 also update tokens_seen and set it to false.
2545 * driver.cs: Implement --recurse for Mike.
2547 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
2548 correctly splitting out the paths.
2550 2002-03-18 Miguel de Icaza <miguel@ximian.com>
2552 * interface.cs (Interface.PopulateProperty): Instead of using
2553 `parent' as the declaration space for the set parameters, use
2556 * support.cs (InternalParameters): InternalParameters constructor
2557 takes a DeclSpace instead of a TypeContainer.
2559 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
2560 types are being initialized, load the address of it before calling
2563 (New): Provide a mechanism to disable the generation of local
2564 value type temporaries when the caller will be providing us with
2565 an address to store it.
2567 (ArrayCreation.EmitDynamicInitializers): Use it.
2569 2002-03-17 Miguel de Icaza <miguel@ximian.com>
2571 * expression.cs (Invocation.EmitArguments): Only probe for array
2572 property if there is more than one argument. Sorry about that.
2574 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
2577 * class.cs (Method.LabelParameters): Fix incorrect code path that
2578 prevented the `ParamArrayAttribute' from being applied to the
2581 2002-03-16 Miguel de Icaza <miguel@ximian.com>
2583 * support.cs (ReflectionParameters): Correctly compute whether the
2584 last argument is a params array. Fixes the problem with
2587 * typemanager.cs: Make the assemblies array always be non-null
2588 (empty, but non-null)
2590 * tree.cs (RecordDecl): New function that abstracts the recording
2591 of names. This reports error 101, and provides a pointer to the
2592 previous declaration. Fixes a crash in the compiler.
2594 * cs-parser.jay (constructor_declaration): Update to new grammar,
2595 and provide a constructor_body that can be empty.
2597 2002-03-15 Miguel de Icaza <miguel@ximian.com>
2599 * driver.cs: Add support for --resources.
2601 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
2602 Make all types for the various array helper methods be integer.
2604 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
2605 CheckState to ConvCast.
2607 (ConvCast): Now it takes a `checked' state argument, to avoid
2608 depending on the emit context for the conversion, and just using
2609 the resolve time setting.
2611 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
2612 instead of Invocation.EmitArguments. We do not emit the original
2613 arguments, instead we emit those which have been converted to
2614 unsigned int expressions.
2616 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
2618 * codegen.cs: ditto.
2620 * expression.cs (LocalVariableReference): Drop the use of the
2621 Store function that depended on the variable index.
2623 * statement.cs (VariableInfo): Drop the `Idx' property from this
2624 class, as this is not taking into account the indexes for
2625 temporaries tat we generate during the execution, getting the
2628 * class.cs: First emit class initializers, then call the parent
2631 * expression.cs (Binary): Fix opcode emision.
2632 (UnaryMutator.EmitCode): Support checked code generation
2634 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
2635 matches for events for both the Static and Instance scans,
2636 pointing to the same element. Fix that.
2638 2002-03-14 Miguel de Icaza <miguel@ximian.com>
2640 * rootcontext.cs (ResolveTree): Always set the
2641 interface_resolve_order, because nested interfaces will be calling
2644 * class.cs (GetInterfaceOrClass): Track the same resolution
2645 process used by TypeManager.LookupType. This fixes the nested
2646 type lookups in class declarations (separate path from
2649 (TypeContainer.DefineType): Also define nested interfaces.
2650 (TypeContainer.RegisterOrder): New public function used to
2651 register the order in which child interfaces need to be closed.
2653 Nested interfaces need to be closed after their parents have been
2656 * interface.cs (InterfaceAttr): Put all the logic for computing
2657 the interface attribute here.
2659 (DefineInterface): Register our interface order with the
2660 RootContext or with the TypeContainer depending on the case.
2662 2002-03-12 Miguel de Icaza <miguel@ximian.com>
2664 * cs-parser.jay: rework foreach statement to work with the new
2665 changes to the policy on SimpleNames.
2667 * report.cs: support Stacktrace on warnings as well.
2669 * makefile: drop --unsafe and /unsafe from the compile.
2671 2002-03-13 Ravi Pratap <ravi@ximian.com>
2673 * ecore.cs (StandardConversionExists): Modify to take an Expression
2674 as the first parameter. Ensure we do null -> reference type conversion
2677 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
2678 temporary Expression objects.
2680 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
2682 * interface.cs: workaround bug in method overloading resolution
2683 (there is already a bugzilla bug for it).
2685 2002-03-12 Miguel de Icaza <miguel@ximian.com>
2687 We could also solve this problem by having a separate path for
2688 performing type lookups, instead of DoResolve, we could have a
2689 ResolveType entry point, and only participating pieces of the
2690 production (simplename, deref, array) would implement this.
2692 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
2693 signal SimpleName to only resolve type names and not attempt to
2694 resolve anything else.
2696 * expression.cs (Cast): Set the flag.
2698 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
2700 * class.cs: Only report 108 if there is no `new' modifier.
2702 * cs-parser.jay: rework foreach statement to work with the new
2703 changes to the policy on SimpleNames.
2705 * report.cs: support Stacktrace on warnings as well.
2707 * makefile: drop --unsafe and /unsafe from the compile.
2709 2002-03-11 Miguel de Icaza <miguel@ximian.com>
2711 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
2712 lookups here, instead of doing that at parse time. This means
2713 that our grammar will not introduce `LocalVariableReferences' as
2714 expressions at this point. That solves the problem of code like
2722 This is only half the fix. The full fix requires parameters to
2723 also be handled in this way.
2725 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
2726 makes the use more obvious of the DeclSpace. The
2727 ec.TypeContainer.TypeBuilder is now only used to pull the
2730 My theory is that I can get rid of the TypeBuilder completely from
2731 the EmitContext, and have typecasts where it is used (from
2732 DeclSpace to where it matters).
2734 The only pending problem is that the code that implements Aliases
2735 is on TypeContainer, and probably should go in DeclSpace.
2737 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
2738 lookups here, instead of doing that at parse time. This means
2739 that our grammar will not introduce `LocalVariableReferences' as
2740 expressions at this point. That solves the problem of code like
2748 This is only half the fix. The full fix requires parameters to
2749 also be handled in this way.
2751 * class.cs (Property.DefineMethod): When implementing an interface
2752 method, set newslot, when implementing an abstract method, do not
2753 set the flag (before we tried never setting it, or always setting
2754 it, which is the difference).
2755 (Indexer.DefineMethod): same.
2756 (Method.DefineMethod): same.
2758 * ecore.cs: Only set the status used flag if we get back a Field.
2760 * attribute.cs: Temporary hack, so Paolo can keep working.
2762 2002-03-08 Ravi Pratap <ravi@ximian.com>
2764 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
2765 the unmanaged type in the case we have a MarshalAs attribute.
2767 (Resolve): Handle the case when we are parsing the special MarshalAs
2768 attribute [we need to store the unmanaged type to use later]
2770 * typemanager.cs (marshal_as_attr_type): Built in type for the
2771 MarshalAs Attribute.
2773 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
2774 on parameters and accordingly set the marshalling info.
2776 2002-03-09 Miguel de Icaza <miguel@ximian.com>
2778 * class.cs: Optimizing slightly by removing redundant code after
2779 we switched to the `NoTypes' return value.
2780 (Property.DefineMethod): use NoTypes here too.
2782 This fixes the bug I introduced in my last batch of changes.
2784 2002-03-05 Ravi Pratap <ravi@ximian.com>
2786 * tree.cs (RecordEnum): Add. We now keep track of enums too.
2788 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
2789 Enums since those are types too.
2791 * cs-parser.jay (enum_declaration): Record enums as we parse them.
2793 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
2794 thanks to a call during the lookup process.
2796 2002-03-07 Miguel de Icaza <miguel@ximian.com>
2798 * statement.cs (Foreach): Lots of work to accomodate a particular
2799 kind of foreach statement that I had not kept in mind. It is
2800 possible to have foreachs on classes that provide a GetEnumerator
2801 method that return objects that implement the "pattern" for using
2802 a foreach, there is no need to support GetEnumerator
2805 This is needed to compile nant.
2807 * decl.cs: Only report 114 if the member is not `Finalize' and if
2808 the warning level is at least 2.
2810 * class.cs: Moved the compare function from Method to
2813 (MethodSignature.InheritableMemberSignatureCompare): Add new
2814 filter function that is used to extract inheritable methods from a
2817 (Method.Define): Use the new `inheritable_method_signature_filter'
2820 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
2823 2002-03-06 Miguel de Icaza <miguel@ximian.com>
2825 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
2827 * cs-parser.jay: Add opt_semicolon to the interface declaration.
2829 * expression.cs: Pass location information to
2830 ConvertImplicitStandard.
2832 * class.cs: Added debugging code to track return values from
2835 2002-03-05 Miguel de Icaza <miguel@ximian.com>
2837 * expression.cs (Is.DoResolve): If either side of the `is' is an
2838 interface, do not flag the warning.
2840 * ecore.cs (ImplicitReferenceConversion): We need a separate test
2843 * report.cs: Allow for --fatal to be used with --probe.
2845 * typemanager.cs (NoTypes): Move the definition for the empty Type
2848 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
2850 (TypeContainer.DefineProxy): New function used to proxy to parent
2851 implementations when implementing interfaces.
2852 (TypeContainer.ParentImplements): used to lookup if our parent
2853 implements a public function that is required by an interface.
2854 (TypeContainer.VerifyPendingMethods): Hook this up.
2856 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
2857 `modules' and `assemblies' arraylists into arrays. We only grow
2858 these are the very early start up of the program, so this improves
2859 the speedof LookupType (nicely measured).
2861 * expression.cs (MakeByteBlob): Replaced unsafe code with
2862 BitConverter, as suggested by Paolo.
2864 * cfold.cs (ConstantFold.Binary): Special case: perform constant
2865 folding of string concatenation, but if either side is a string,
2866 and the other is not, then return null, and let the runtime use
2867 the concatenation on the string plus the object (using
2870 2002-03-04 Miguel de Icaza <miguel@ximian.com>
2872 Constant Folding has been implemented now.
2874 * expression.cs (Unary.Reduce): Do not throw an exception, catch
2875 the error instead on types that are not supported in one's
2878 * constant.cs (Constant and all children): New set of functions to
2879 perform implict and explicit conversions.
2881 * ecore.cs (EnumConstant): Implement the new functions to perform
2882 conversion by proxying to the child expression.
2884 * codegen.cs: (ConstantCheckState): Constant evaluation has its
2885 own separate setting that can not be turned off from the command
2886 line using --unchecked or --checked and is only controlled using
2887 the checked/unchecked statements and expressions. This setting is
2888 used by the constant folder to flag errors.
2890 * expression.cs (CheckedExpr, UncheckedExpr): Set the
2891 ConstantCheckState as well.
2893 During Resolve, they also have to flag the state, because the
2894 constant folder runs completely in the Resolve phase.
2896 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
2899 2002-03-01 Miguel de Icaza <miguel@ximian.com>
2901 * cfold.cs: New file, this file contains the constant folder.
2903 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
2904 argument to track whether we are using the resulting address to
2905 load or store a value and provide better error messages.
2907 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
2908 new AddressOf arguments.
2910 * statement.cs (Foreach.EmitCollectionForeach): Update
2912 * expression.cs (Argument.Emit): Call AddressOf with proper
2913 arguments to track usage.
2915 (New.DoEmit): Call AddressOf with new arguments.
2917 (Unary.Emit): Adjust AddressOf call.
2919 2002-03-01 Ravi Pratap <ravi@ximian.com>
2921 * cs-parser.jay (member_access): Change the case for pre-defined types
2922 to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
2925 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
2928 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
2929 essentially like methods and apply attributes like MethodImplOptions to them too.
2931 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
2934 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
2935 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
2938 * Update code everywhere accordingly.
2940 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
2942 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
2944 2002-02-28 Ravi Pratap <ravi@ximian.com>
2946 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
2947 try performing lookups against those instead of jumping straight into using
2948 the 'using' clauses.
2950 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
2952 (LookupType): Perform lookups in implicit parents too.
2954 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
2955 sequence as RootContext.LookupType.
2957 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
2958 the various cases of namespace lookups into this method.
2960 2002-03-01 Miguel de Icaza <miguel@ximian.com>
2962 * cs-parser.jay: Add support for [Attribute ()] (empty arguments
2963 in positional arguments)
2965 * class.cs (Operator): Update the AllowedModifiers to contain
2968 * cs-parser.jay: Update operator declaration to allow for the
2969 operator body to be empty.
2971 * cs-tokenizer.cs: Added '\u' unicode support in strings and hex
2974 2002-02-27 Miguel de Icaza <miguel@ximian.com>
2976 * class.cs (Method.Emit): Label parameters.
2978 * driver.cs: Return 1 or 0 as the program exit code.
2980 2002-02-26 Miguel de Icaza <miguel@ximian.com>
2982 * expression.cs: Special case the `null' object when trying to
2983 auto-compute the type, as anything can be explicitly converted to
2986 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
2987 spotting this Paolo.
2989 (Expression.ImplicitNumericConversion): Perform comparissions of
2990 the type using the underlying type in the case of an enumeration
2991 rather than using the enumeration type for the compare.
2993 Cope with the underlying == type case, which is not possible to
2996 (Expression.ConvertNumericExplicit): Perform comparissions of
2997 the type using the underlying type in the case of an enumeration
2998 rather than using the enumeration type for the compare.
3000 * driver.cs: If the user does not supply an extension, assume .exe
3002 * cs-parser.jay (if_statement): Rewrote so that we can track the
3003 location for the if statement.
3005 * expression.cs (Binary.ConstantFold): Only concat strings when
3006 the operation is "+", not everything ;-)
3008 * statement.cs (Statement.EmitBoolExpression): Take a location
3010 (If, While, Do): Track location.
3012 * expression.cs (Binary.ResolveOperator): In the object + string
3013 case, I was missing a call to ConvertImplicit
3015 2002-02-25 Ravi Pratap <ravi@ximian.com>
3017 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
3018 Location arguments. Ensure we use RootContext.LookupType to do our work
3019 and not try to do a direct Type.GetType and ModuleBuilder.GetType
3021 * interface.cs (PopulateMethod): Handle the type of the parameter being
3024 * expression.cs (Invocation.BetterFunction): Handle the case when we
3025 have a params method with no fixed arguments and a call is made with no
3028 2002-02-25 Miguel de Icaza <miguel@ximian.com>
3030 * cs-tokenizer.cs: Add support for the quote-escape-sequence in
3031 the verbatim-string-literal
3033 * support.cs (InternalParameters.ParameterModifier): handle null
3035 (InternalParameters.ParameterType): ditto.
3037 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
3038 duplicating the name of the variable parameter.
3039 (GetParameterByName): Fix bug where we were not looking up array
3040 paramters if they were the only present (thanks Paolo!).
3041 (GetParameterInfo): We only have an empty set of types if both
3042 fixed and array are set to null.
3043 (GetParameterInfo-idx): Handle FixedParameter == null
3045 * cs-parser.jay: Handle the case where there is no catch
3046 statements (missing null test).
3048 2002-02-22 Miguel de Icaza <miguel@ximian.com>
3050 * driver.cs (MainDriver): Be conservative on our command line
3053 Catch DirectoryNotFoundException when calling GetFiles.
3055 (SplitPathAndPattern): Used to split the input specification into
3056 a path and a pattern that we can feed to Directory.GetFiles.
3058 2002-02-21 Miguel de Icaza <miguel@ximian.com>
3060 * statement.cs (Fixed): Implement the last case of the Fixed
3061 statement (string handling).
3063 * expression.cs (StringPtr): New class used to return a char * to
3064 a string; Used by the Fixed statement.
3066 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
3068 * expression.cs (Binary.ResolveOperator): Remove redundant
3069 MemberLookup pn parent type.
3070 Optimize union call, we do not need a union if the types are the same.
3071 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
3074 Specialize the use of MemberLookup everywhere, instead of using
3075 the default settings.
3077 (StackAlloc): Implement stackalloc keyword.
3079 * cs-parser.jay: Add rule to parse stackalloc.
3081 * driver.cs: Handle /h, /help, /?
3083 * expression.cs (MakeByteBlob): Removed the hacks we had in place
3084 before we supported unsafe code.
3086 * makefile: add --unsafe to the self compilation of mcs.
3088 2002-02-20 Miguel de Icaza <miguel@ximian.com>
3090 * expression.cs (PointerArithmetic): New class that is used to
3091 perform pointer arithmetic.
3092 (Binary.Resolve): Handle pointer arithmetic
3093 Handle pointer comparission.
3094 (ArrayPtr): Utility expression class that is used to take the
3095 address of an array.
3097 (ElementAccess): Implement array access for pointers
3099 * statement.cs (Fixed): Implement fixed statement for arrays, we
3100 are missing one more case before we are done.
3102 * expression.cs (Indirection): Implement EmitAssign and set the
3103 ExprClass to Variable. This allows pointer dereferences to be
3104 treated as variables, and to have values assigned to them.
3106 * ecore.cs (Expression.StoreFromPtr): New utility function to
3107 store values dereferencing.
3109 2002-02-20 Ravi Pratap <ravi@ximian.com>
3111 * expression.cs (Binary.ResolveOperator): Ensure that we are
3112 not trying to operate on a void type - this fixes the reported
3115 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
3116 the parent implementation is sealed.
3118 * ../errors/cs0239.cs : Add.
3120 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
3122 * typemanager.cs (unverifiable_code_type): Corresponds to
3123 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
3124 which have unsafe code in them.
3126 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
3129 2002-02-19 Miguel de Icaza <miguel@ximian.com>
3131 * cs-tokenizer.cs: Add support for @"litreal strings"
3133 Make tokenizer accept pre-processor directives
3134 on any column (remove the old C-like limitation).
3136 * rootcontext.cs (EmitCode): Emit any global attributes.
3137 (AddGlobalAttributes): Used to keep track of assembly attributes.
3139 * attribute.cs (ApplyAttributes): Support AssemblyAttributes.

3143 2002-02-17 Miguel de Icaza <miguel@ximian.com>
3145 * expression.cs (Indirection): New helper class. Unary will
3146 create Indirection classes to be able to implement the
3147 IMemoryLocation interface on it.
3149 2002-02-16 Miguel de Icaza <miguel@ximian.com>
3151 * cs-parser.jay (fixed_statement): reference the right statement.
3153 * statement.cs (Fixed.Emit): Finish implementing the fixed
3154 statement for the &x case.
3156 2002-02-14 Miguel de Icaza <miguel@ximian.com>
3158 * class.cs (Property.Define, Method.Define): Remove newslot when
3161 * modifiers.cs: My use of NewSlot when `Abstract' was set was
3162 wrong. NewSlot should only be used if the `new' keyword is present.
3164 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
3165 locating our system dir. Sorry about this.
3167 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3169 * driver.cs (GetSystemDir): Compute correctly the location of our
3170 system assemblies. I was using the compiler directory instead of
3171 the library directory.
3173 2002-02-13 Ravi Pratap <ravi@ximian.com>
3175 * expression.cs (BetterFunction): Put back in what Miguel commented out
3176 since it is the correct fix. The problem is elsewhere ;-)
3178 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
3179 parameters of the parms method are themselves compatible or not !
3181 (StandardConversionExists): Fix very dangerous bug where we were forgetting
3182 to check that a class implements an interface before saying that an implicit
3183 conversion was allowed. Use ImplementsInterface to do the checking.
3185 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3187 * class.cs (Method.Define): Track whether we are an explicit
3188 implementation or not. And only call DefineMethodOverride if we
3189 are an explicit implementation.
3191 (Property.DefineMethod): Ditto.
3193 2002-02-11 Ravi Pratap <ravi@ximian.com>
3195 * expression.cs (BetterFunction): Catch hideous bug which was
3196 preventing us from detecting ambiguous calls due to implicit casts i.e
3199 2002-01-29 Miguel de Icaza <miguel@ximian.com>
3201 * support.cs (Pair): Remove un-needed method. I figured why I was
3202 getting the error in cs-parser.jay, the variable in a foreach loop
3203 is readonly, and the compiler does not really treat this as a variable.
3205 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
3206 instead of EQUALS in grammar.
3208 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
3210 * expression.cs (Unary.DoResolve): Check whether the argument is
3213 2002-01-28 Miguel de Icaza <miguel@ximian.com>
3215 * support.cs: Api for Pair to set a value. Despite the fact that
3216 the variables are public the MS C# compiler refuses to compile
3217 code that accesses the field if the variable is part of a foreach
3220 * statement.cs (Fixed): Begin implementation of the fixed
3223 (Block.AddVariable): Return the VariableInfo on success and null
3224 on failure instead of true/false.
3226 * cs-parser.jay (foreach): Catch errors on variables already
3227 defined (we were ignoring this value before) and properly unwind
3230 (fixed_statement): grammar for the fixed statement.
3232 2002-01-25 Miguel de Icaza <miguel@ximian.com>
3234 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
3235 pointer types to be incretemented.

3246 (Unary): Implement indirection.
3248 * ecore.cs (Expression.UnsafeError): Reports error 214 (pointer
3249 use in non-unsafe context).
3251 (SimpleName.DoResolve): Check for pointers in field access on safe
3254 (Expression.LoadFromPtr): Factor the load-indirect code in this
3255 function. This was duplicated in UnboxCast and ParameterReference
3257 2002-01-24 Miguel de Icaza <miguel@ximian.com>
3259 * expression.cs (ComposedCast): report an error if a pointer cast
3260 is used in a safe region.
3262 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
3263 pointer type casts in unsafe context.
3265 * codegen.cs (EmitContext): Set up IsUnsafe.
3267 * cs-parser.jay (non_expression_type): Add productions for pointer
3270 * expression.cs (Invocation.EmitCall): Remove chunk of buggy
3271 code. We should not use force into static mode if the method is
3272 not virtual. Fixes bug in MIS
3274 * statement.cs (Do.Emit, While.Emit, For.Emit,
3275 Statement.EmitBoolExpression): Add support to Do and While to
3276 propagate infinite loop as `I do return' semantics.
3278 Improve the For case to also test for boolean constants.
3280 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
3281 to the list of attributes we can add.
3283 Remove `EmitContext' argument.
3285 * class.cs (Method.Define): Apply parameter attributes.
3286 (Constructor.Define): Apply parameter attributes.
3287 (MethodCore.LabelParameters): Move here the core of labeling
3290 * support.cs (ReflectionParameters.ParameterModifier,
3291 InternalParameters.ParameterModifier): Use IsByRef on the type and
3292 only return the OUT bit for these parameters instead of in/out/ref
3295 This is because I miss-understood things. The ParameterInfo.IsIn
3296 and IsOut represent whether the parameter has the [In] and [Out]
3299 2002-01-22 Miguel de Icaza <miguel@ximian.com>
3301 * ecore.cs (FieldExpr.Emit): Release temporaries.
3303 * assign.cs (LocalTemporary.Release): new function.
3305 * codegen.cs (EmitContext.GetTemporaryStorage,
3306 EmitContext.FreeTemporaryStorage): Rework the way we deal with
3307 temporary storage. Now we can "put back" localbuilders when we
3310 2002-01-21 Miguel de Icaza <miguel@ximian.com>
3312 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
3313 need to make a copy of the variable to generate verifiable code.
3315 2002-01-19 Miguel de Icaza <miguel@ximian.com>
3317 * driver.cs: Compute dynamically the system directory.
3319 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
3320 Slower, but more generally useful. Used by the abstract
3321 registering implementation.
3323 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
3324 the rules for the special rule on Type/instances. First check if
3325 we have the same name, and if so, try that special static path
3326 rather than the instance path.
3328 2002-01-18 Miguel de Icaza <miguel@ximian.com>
3330 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
3333 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
3334 Enum, ValueType, Delegate or Array for non-corlib compiles.
3336 * cs-tokenizer.cs: Catch long identifiers (645)
3338 * typemanager.cs (IndexerPropetyName): Ravi never tested this
3341 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
3342 fix, we were returning too early, so we were not registering
3343 pending methods from abstract classes.
3345 Do not register pending methods if the class is abstract.
3347 * expression.cs (Conditional.DoResolve): Report circular implicit
3348 conversions when we neecd to compute it for conditional
3351 (Is.DoResolve): If the expression is always of the provided type,
3352 flag warning 183. If the expression can not ever be of the
3353 provided type flag warning 184.
3355 * class.cs: Catch 169 as well.
3357 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
3360 2002-01-18 Nick Drochak <ndrochak@gol.com>
3362 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.
3364 2002-01-17 Miguel de Icaza <miguel@ximian.com>
3366 * interface.cs: (PopulateMethod): Check for pointers being defined
3367 only if the unsafe context is active.
3368 (PopulateProperty): ditto.
3369 (PopulateIndexer): ditto.
3371 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
3372 specified. If pointers are present, make sure that they are
3373 present in an unsafe context.
3374 (Constructor, Constructor.Define): ditto.
3375 (Field, Field.Define): ditto.
3376 (Property, Property.Define): ditto.
3377 (Event, Event.Define): ditto.
3379 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
3380 hashtable if there are classes or structs defined.
3382 * expression.cs (LocalVariableReference.DoResolve): Simplify this
3383 code, as the constant resolution moved.
3385 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
3386 the metadata, so we can flag error 133.
3388 * decl.cs (MemberCore.UnsafeOK): New function to test that a
3389 pointer is being declared in an unsafe context.
3391 2002-01-16 Miguel de Icaza <miguel@ximian.com>
3393 * modifiers.cs (Modifiers.Check): Require a Location argument.
3394 Report error 227 for Unsafe use.
3396 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
3398 * statement.cs (For.Emit): If the test is null, then report that
3399 we do `return', as we wont reach anything afterwards.
3401 (Switch.SwitchGoverningType): Track the expression that matched
3404 * driver.cs: Allow negative numbers as an error code to flag.
3406 * cs-parser.jay: Handle 1551.
3408 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
3410 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3412 * cs-parser.jay: Report 1518 (type declaration can only contain
3413 class, struct, interface, enum or delegate)
3415 (switch_label): Report 1523 (keywords `case' or `default' must
3418 (opt_switch_sections): Report 1522 (empty switch)
3420 * driver.cs: Report 1515 (response file specified multiple times)
3421 Report 1516 (Source file specified multiple times).
3423 * expression.cs (Argument.Resolve): Signal 1510
3425 (BaseAccess.Resolve, BaseIndexer.Resolve): Signal 1511 (base
3426 access not allowed in static code)
3428 2002-01-11 Ravi Pratap <ravi@ximian.com>
3430 * typemanager.cs (IsPointerType): Utility method which we are going
3433 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
3434 the object type, so we take care of that.
3436 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
3438 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
3439 added to non-params parameters :-)
3441 * typemanager.cs (CSharpName): Include 'void' type too.
3443 (void_ptr_type): Include in the set of core types.
3445 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
3448 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
3451 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
3452 completely forgotten about it.
3454 2002-01-10 Ravi Pratap <ravi@ximian.com>
3456 * cs-parser.jay (pointer_type): Add. This begins our implementation
3457 of parsing rules for unsafe code.
3459 (unsafe_statement): Implement.
3461 (embedded_statement): Modify to include the above.
3463 * statement.cs (Unsafe): Implement new class for unsafe blocks.
3465 * codegen.cs (EmitContext.InUnsafe): Add. This determines
3466 if the current context is an unsafe one.
3468 * cs-parser.jay (local_variable_pointer_type): Since local variable types
3469 are handled differently, we need separate rules for them.
3471 (local_variable_declaration): Update to use local_variable_pointer_type
3472 to allow variable declarations of unmanaged pointer types.
3474 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
3477 * ../errors/cs0214.cs : Add.
3479 2002-01-16 Nick Drochak <ndrochak@gol.com>
3481 * makefile: remove 'response' file when cleaning.
3483 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3485 * cs-parser.jay: Report 1524.
3487 2002-01-14 Miguel de Icaza <miguel@ximian.com>
3489 * typemanager.cs (RegisterMethod): drop checking if we have
3490 registered this from here
3492 2002-01-12 Miguel de Icaza <miguel@ximian.com>
3494 * class.cs (Method.EmitDestructor): Implement calling our base
3497 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
3500 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
3501 this routine and will wrap the call in a try/catch block. Deal
3504 2002-01-11 Miguel de Icaza <miguel@ximian.com>
3506 * ecore.cs (Expression.MemberLookup): instead of taking a
3507 parameter `same_type' that was used to tell whether we could
3508 access private members we compute our containing type from the
3511 (FieldExpr): Added partial support for volatile fields. This does
3512 not work for volatile fields exposed from assemblies, as I can not
3513 figure out how to extract the modreq from it.
3515 Updated all the source files to use this.
3517 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
3518 because it is referenced by MemberLookup very often.
3520 2002-01-09 Ravi Pratap <ravi@ximian.com>
3522 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
3523 TypeBuilder.GetCustomAttributes to retrieve what we need.
3525 Get rid of redundant default_member_attr_type as this is the same as
3526 default_member_type which already exists.
3528 * interface.cs, attribute.cs : Update accordingly.
3530 2002-01-08 Miguel de Icaza <miguel@ximian.com>
3532 * typemanager.cs: Enable IndexerPropertyName again. It does not
3533 work for TYpeBuilders though. Ravi, can you please fix this?
3535 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
3537 * expression.cs (Argument.Emit): Handle the case of ref objects
3538 being passed to ref functions;
3540 (ParameterReference.EmitLoad): Loads the content of the pointer
3541 without dereferencing.
3543 2002-01-07 Miguel de Icaza <miguel@ximian.com>
3545 * cs-tokenizer.cs: Implemented the pre-processing expressions.
3547 2002-01-08 Ravi Pratap <ravi@ximian.com>
3549 * class.cs (Indexer.DefineMethod): Incorporate the interface
3550 type in the name of the method if we are doing explicit interface
3553 * expression.cs (ConversionExists): Remove as it is completely obsolete.
3555 (BetterConversion): Fix extremely trivial bug where we were referring to
3556 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
3559 * ../errors/bug16.cs : Add although we have fixed it.
3561 2002-01-07 Miguel de Icaza <miguel@ximian.com>
3563 * expression.cs (BaseIndexer): Begin implementation.
3565 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
3567 * cs-parser.jay (indexer_declarator): Use qualified_identifier
3568 production directly to remove a shift/reduce, and implement
3569 explicit interface implementation.
3571 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
3572 after a floating point suffix.
3574 * expression.cs (DoNumericPromotions): Improved the conversion for
3575 uint/uint. If we have a constant, we avoid doing a typecast to a
3578 * class.cs (Indexer): Implement explicit interface implementation
3581 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
3583 * class.cs: make the default instance constructor public and hidebysig.
3585 2001-01-03 Ravi Pratap <ravi@ximian.com>
3587 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
3588 so we can call it from elsewhere.
3590 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
3591 we emit it internally if the class has a defined indexer; otherwise the user
3592 emits it by decorating the class definition with the DefaultMemberAttribute.
3594 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
3595 attribute is not used on a type which defines an indexer.
3597 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
3598 character when we skip whitespace.
3600 * ../errors/cs0646.cs : Add.
3602 2002-01-03 Miguel de Icaza <miguel@ximian.com>
3604 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
3607 * makefile: Add practical target `mcs3.exe' which builds the third
3608 generation compiler.
3610 * expression.cs (New): Fix structures constructor calling.
3612 * class.cs (Property, Method, Indexer): Emit Final flag on the
3613 method if we are an interface implementation and we are not
3616 * ecore.cs (PropertyExpr): New public field `IsBase', tells
3617 whether this property is referencing a `base' method.
3619 * expression.cs (Invocation.EmitCall): take an extra argument:
3620 is_base, this is used to determine whether the `call' or
3621 `callvirt' opcode should be used.
3624 * delegate.cs: update EmitCall.
3626 * class.cs (Method.Define): Set NewSlot for the cases where we are
3627 not implementing an interface method.
3629 (Property.Define): ditto.
3631 2002-01-02 Miguel de Icaza <miguel@ximian.com>
3633 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
3634 'r'. Allows mcs to parse itself fully.
3636 2002-01-02 Ravi Pratap <ravi@ximian.com>
3638 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
3639 of the number of initializers that require the InitializeArray method.
3641 (CheckIndices): Store the Expression in all cases - not the plain value. Also
3642 update the above field where necessary.
3644 (MakeByteBlob): Update accordingly.
3646 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
3649 (EmitDynamicInitializers): Update in accordance with the new optimization.
3651 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
3652 same OpCode applies.
3654 * cs-parser.jay : Fix some glaring errors I introduced.
3656 2002-01-01 Ravi Pratap <ravi@ximian.com>
3658 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
3659 so that we can check for name clashes there too.
3661 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
3662 for interface indexers.
3664 * interfaces.cs (Define): Emit the default member attribute.
3666 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
3667 variable was being referred to while setting the value ;-)
3669 2002-01-01 Miguel de Icaza <miguel@ximian.com>
3671 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
3672 byte-by-byte information when we know the data is zero.
3674 Make the block always a multiple of 4, because
3675 DefineInitializedData has a bug.
3677 * assign.cs: Fix, we should assign from the temporary, not from
3680 * expression.cs (MakeByteBlob): Fix my incorrect code.
3682 2001-12-31 Miguel de Icaza <miguel@ximian.com>
3684 * typemanager.cs (EnumToUnderlying): This function is used to get
3685 the underlying type from an enumeration, because it does not
3688 * constant.cs: Use the I4_S form for values between -128 and 127.
3690 * statement.cs (Block.LookupLabel): Looks up a label.
3691 (Block): Drop support for labeled blocks.
3693 (LabeledStatement): New kind of statement that represents a label
3696 (Goto): Finally implement this bad boy.
3698 * cs-parser.jay: Update to reflect new mechanism to implement
3701 2001-12-30 Miguel de Icaza <miguel@ximian.com>
3703 * codegen.cs (EmitContext.This): a codegen property that keeps the
3704 a single instance of this instead of creating many different this
3707 * delegate.cs (Delegate.DoResolve): Update to use the property;
3709 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
3711 * expression.cs (BaseAccess.DoResolve): Ditto.
3713 2001-12-29 Ravi Pratap <ravi@ximian.com>
3715 * typemanager.cs (methodimpl_attr_type): Add to hold the type
3716 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
3718 (InitCoreTypes): Update accordingly.
3720 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
3721 so we can quickly store the state.
3723 (ApplyAttributes): Set the correct implementation flags
3724 for InternalCall methods.
3726 2001-12-29 Miguel de Icaza <miguel@ximian.com>
3728 * expression.cs (EmitCall): if a method is not virtual, then do
3729 not use callvirt on it.
3731 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
3732 user defined stuff) requires the use of stobj, which takes an
3733 address on the stack instead of an array and an index. So emit
3734 the Ldelema operation for it.
3736 (EmitStoreOpcode): Use stobj for valuetypes.
3738 (UnaryMutator.EmitCode): Use the right 1 value depending on
3739 whether we are dealing with int64/uint64, float or doubles.
3741 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
3742 constructors that I implemented last night.
3744 (Constructor.IsDefault): Fix to work properly for static
3747 * cs-parser.jay (CheckDef): report method signature errors.
3748 Update error number 103 to be 132.
3750 * decl.cs: New AdditionResult enumeration value: MethodExists.
3751 Although we do this check for methods later on in the semantic
3752 analysis, catching repeated default constructors is so easy that
3753 we catch these here.
3755 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
3758 (ParameterReference.EmitAssign, Emit): handle
3761 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
3762 (ArrayAccess.EmitStoreOpcode): ditto.
3764 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
3766 * expression.cs (MakeByteBlob): Complete all the missing types
3767 (uint, short, ushort, byte, sbyte)
3769 * class.cs: Only init instance field initializers on instance
3772 Rename `constructors' to instance_constructors.
3774 (TypeContainer.AddConstructor): Only add constructors to the list
3775 if it is not static.
3777 Make sure that we handle default_static_constructor independently
3778 everywhere where we handle instance_constructors
3780 2001-12-28 Miguel de Icaza <miguel@ximian.com>
3782 * class.cs: Do not lookup or create a base initializer for a
3785 (ConstructorInitializer.Resolve): use the proper type to lookup
3788 * cs-parser.jay: Report error 1585 (modifiers between type and name).
3790 * enum.cs, interface.cs: Remove CloseType, this is taken care by
3793 * decl.cs: CloseType is now an virtual method, the default
3794 implementation just closes this type.
3796 2001-12-28 Ravi Pratap <ravi@ximian.com>
3798 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
3799 to PreserveSig by default. Also emit HideBySig on such methods.
3801 Basically, set the defaults to standard values.
3803 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
3804 argument, if candidate is better, it can't be worse than the best !
3806 (Invocation): Re-write bits to differentiate between methods being
3807 applicable in their expanded form and their normal form - for params
3810 Get rid of use_standard everywhere as only standard conversions are allowed
3811 in overload resolution.
3813 More spec conformance.
3815 2001-12-27 Miguel de Icaza <miguel@ximian.com>
3817 * driver.cs: Add --timestamp, to see where the compiler spends
3820 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
3821 `this' in static code.
3823 (SimpleName.DoResolve): Implement in terms of a helper function
3824 that allows static-references to be passed upstream to
3827 (Expression.ResolveWithSimpleName): Resolve specially simple
3828 names when called by MemberAccess to implement the special
3831 (Expression.ImplicitReferenceConversion): Handle conversions from
3832 Null to reference types before others, as Null's type is
3835 * expression.cs (Invocation.EmitCall): Handle the special case of
3836 calling methods declared on a reference type from a ValueType
3837 (Base classes System.Object and System.Enum)
3839 (MemberAccess.Resolve): Only perform lookups on Enumerations if
3840 the left hand side is a TypeExpr, not on every enumeration.
3842 (Binary.Resolve): If types are reference types, then do a cast to
3843 object on operators != and == of both arguments.
3845 * typemanager.cs (FindMembers): Extract instance and static
3846 members if requested.
3848 * interface.cs (PopulateProperty): Use void_type instead of null
3849 as the return type for the setter method.
3851 (PopulateIndexer): ditto.
3853 2001-12-27 Ravi Pratap <ravi@ximian.com>
3855 * support.cs (ReflectionParameters): Fix minor bug where we
3856 were examining the wrong parameter for the ParamArray attribute.
3858 Cope with requests for the type of the parameter at position
3859 greater than the params parameter's. We now return the element
3860 type of the params array as that makes more sense.
3862 * expression.cs (Invocation.IsParamsMethodApplicable): Update
3863 accordingly as we no longer have to extract the element type
3866 (Invocation.OverloadResolve): Update.
3868 2001-12-27 Miguel de Icaza <miguel@ximian.com>
3870 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
3871 against IEnumerator, test whether the return value is a descendant
3872 of the IEnumerator interface.
3874 * class.cs (Indexer.Define): Use an auxiliary method to implement
3875 the other bits of the method definition. Begin support for
3876 explicit interface implementation.
3878 (Property.DefineMethod): Use TypeManager.void_type instead of null
3879 for an empty return value.
3881 2001-12-26 Miguel de Icaza <miguel@ximian.com>
3883 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
3884 dealing with a FieldExpr which is composed of a FieldBuilder, in
3885 the code path we did extract the constant, but we should have
3886 obtained the underlying value to be able to cast it (otherwise we
3887 end up in an infinite loop, this is what Ravi was running into).
3889 (ArrayCreation.UpdateIndices): Arrays might be empty.
3891 (MemberAccess.ResolveMemberAccess): Add support for section
3892 14.5.4.1 that deals with the special case of E.I when E is a type
3893 and something else, that I can be a reference to a static member.
3895 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
3896 handle a particular array type to create byte blobs, it is just
3897 something we dont generate byteblobs for.
3899 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
3902 * location.cs (Push): remove the key from the hashtable that we
3903 are about to add. This happens for empty files.
3905 * driver.cs: Dispose files after we have parsed them.
3907 (tokenize): new function that only runs the tokenizer on its
3908 input, for speed testing.
3910 2001-12-26 Ravi Pratap <ravi@ximian.com>
3912 * class.cs (Event.Define): Define the private field only if there
3913 are no accessors defined.
3915 * expression.cs (ResolveMemberAccess): If there is no associated
3916 field with the event, that means we have an event defined with its
3917 own accessors and we should flag error cs0070 since transforming
3918 ourselves into a field is not valid in that case.
3920 * ecore.cs (SimpleName.DoResolve): Same as above.
3922 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
3923 and charset to sane values.
3925 2001-12-25 Ravi Pratap <ravi@ximian.com>
3927 * assign.cs (DoResolve): Perform check on events only if they
3928 are being accessed outside the declaring type.
3930 * cs-parser.jay (event_declarations): Update rules to correctly
3931 set the type of the implicit parameter etc.
3933 (add_accessor, remove_accessor): Set current local parameters.
3935 * expression.cs (Binary): For delegate addition and subtraction,
3936 cast the return value from the method into the appropriate delegate
3939 2001-12-24 Ravi Pratap <ravi@ximian.com>
3941 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
3942 of these as the workaround is unnecessary.
3944 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
3945 delegate data - none of that is needed at all.
3947 Re-write bits to extract the instance expression and the delegate method
3950 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
3953 * attribute.cs (ApplyAttributes): New method to take care of common tasks
3954 of attaching attributes instead of duplicating code everywhere.
3956 * everywhere : Update code to do attribute emission using the above method.
3958 2001-12-23 Miguel de Icaza <miguel@ximian.com>
3960 * expression.cs (IsParamsMethodApplicable): if there are not
3961 parameters, return immediately.
3963 * ecore.cs: The 0 literal can be implicity converted to an enum
3966 (SimpleName.DoResolve): First lookup the type, then lookup the
3969 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
3970 want to get its address. If the InstanceExpression is not
3971 addressable, store the result in a temporary variable, then get
3974 * codegen.cs: Only display 219 errors on warning level or above.
3976 * expression.cs (ArrayAccess): Make it implement the
3977 IMemoryLocation interface.
3979 (Binary.DoResolve): handle the operator == (object a, object b)
3980 and operator != (object a, object b) without incurring into a
3981 BoxedCast (because 5 != o should never be performed).
3983 Handle binary enumerator operators.
3985 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
3986 value type, otherwise use Ldelem_ref.
3988 Use precomputed names;
3990 (AddressOf): Implement address of
3992 * cs-parser.jay (labeled_statement): Fix recursive block
3993 addition by reworking the production.
3995 * expression.cs (New.DoEmit): New has a special case:
3997 If we are dealing with a ValueType, we have a few
3998 situations to deal with:
4000 * The target of New is a ValueType variable, that is
4001 easy, we just pass this as the variable reference
4003 * The target of New is being passed as an argument,
4004 to a boxing operation or a function that takes a
4007 In this case, we need to create a temporary variable
4008 that is the argument of New.
4011 2001-12-23 Ravi Pratap <ravi@ximian.com>
4013 * rootcontext.cs (LookupType): Check that current_type is not null before
4014 going about looking at nested types.
4016 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
4017 not implement the IAssignMethod interface any more.
4019 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
4020 where we tranform them into FieldExprs if they are being resolved from within
4023 * ecore.cs (SimpleName.DoResolve): Do the same here.
4025 * assign.cs (DoResolve, Emit): Clean up code considerably.
4027 * ../errors/bug10.cs : Add.
4029 * ../errors/cs0070.cs : Add.
4031 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
4033 * assign.cs : Get rid of EventIsLocal everywhere.
4035 2001-12-23 Miguel de Icaza <miguel@ximian.com>
4037 * ecore.cs (ConvertIntLiteral): finished the implementation.
4039 * statement.cs (SwitchLabel): Convert the value we are using as a
4040 key before looking up the table.
4042 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4044 * codegen.cs (EmitTopBlock): Require a Location argument now.
4046 * cs-parser.jay (constructor_declarator): We need to setup
4047 current_local_parameters before we parse the
4048 opt_constructor_initializer, to allow the variables to be bound
4049 to the constructor arguments.
4051 * rootcontext.cs (LookupType): First lookup nested classes in our
4052 class and our parents before we go looking outside our class.
4054 * expression.cs (ConstantFold): Extract/debox the values at the
4057 * rootcontext.cs (EmitCode): Resolve the constants first before we
4058 resolve the types. This is not really needed, but it helps debugging.
4060 * statement.cs: report location.
4062 * cs-parser.jay: pass location to throw statement.
4064 * driver.cs: Small bug fix.
4066 * report.cs: Updated format to be 4-zero filled digits.
4068 2001-12-22 Ravi Pratap <ravi@ximian.com>
4070 * expression.cs (CheckIndices): Fix minor bug where the wrong
4071 variable was being referred to ;-)
4073 (DoEmit): Do not call EmitStaticInitializers when the
4074 underlying type is System.Object.
4076 2001-12-21 Ravi Pratap <ravi@ximian.com>
4078 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
4079 and do the usual workaround for SRE.
4081 * class.cs (MyEventBuilder.EventType): New member to get at the type
4082 of the event, quickly.
4084 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
4086 * assign.cs (Assign.DoResolve): Handle the case when the target
4087 is an EventExpr and perform the necessary checks.
4089 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
4092 (SimpleName.MemberStaticCheck): Include check for EventExpr.
4094 (EventExpr): Set the type in the constructor itself since we
4095 are meant to be born fully resolved.
4097 (EventExpr.Define): Revert code I wrote earlier.
4099 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
4100 instance expression is null. The instance expression is a This in that case
4101 or a null, depending on whether it is a static method or not.
4103 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
4104 refers to more than one method.
4106 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
4107 and accordingly flag errors.
4109 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4111 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
4113 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4115 * location.cs (ToString): Provide useful rutine.
4117 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4119 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
4120 objects, return the actual integral boxed.
4122 * statement.cs (SwitchLabel): define an ILLabel for each
4125 (Switch.CheckSwitch): If the value is a Literal, extract
4126 the underlying literal.
4128 Also in the unused hashtable we had, add the SwitchLabel so we can
4129 quickly look this value up.
4131 * constant.cs: Implement a bunch of new constants. Rewrite
4132 Literal based on this. Made changes everywhere to adapt to this.
4134 * expression.cs (Expression.MakeByteBlob): Optimize routine by
4135 dereferencing array only once, and also copes with enumrations.
4137 bytes are two bytes wide, not one.
4139 (Cast): Perform constant conversions.
4141 * ecore.cs (TryImplicitIntConversion): Return literals instead of
4142 wrappers to the literals here.
4144 * expression.cs (DoNumericPromotions): long literals can converted
4145 to ulong implicity (this is taken care of elsewhere, but I was
4148 * ecore.cs (Expression.Literalize): Make the return type Literal,
4149 to improve type checking.
4151 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
4153 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4155 * literal.cs: Revert code from ravi that checked the bounds. The
4156 bounds are sane by the definition of the type itself.
4158 * typemanager.cs: Fix implementation of ImplementsInterface. We
4159 need to actually look up in our parent hierarchy for interfaces
4162 * const.cs: Use the underlying type for enumerations
4164 * delegate.cs: Compute the basename for the delegate creation,
4165 that should fix the delegate test case, and restore the correct
4166 Type Lookup semantics in rootcontext
4168 * rootcontext.cs: Revert Ravi's last patch. The correct way of
4169 referencing a nested type with the Reflection API is using the "+"
4172 * cs-parser.jay: Do not require EOF token at the end.
4174 2001-12-20 Ravi Pratap <ravi@ximian.com>
4176 * rootcontext.cs (LookupType): Concatenate type names with
4177 a '.' instead of a '+' The test suite passes again.
4179 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
4180 field of the enumeration.
4182 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
4183 the case when the member is an EventExpr.
4185 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
4186 static has an associated instance expression.
4188 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
4190 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
4192 * class.cs (Event.Define): Register event and perform appropriate checks
4195 We define the Add and Remove methods even if the use provides none because
4196 in that case, we provide default implementations ourselves.
4198 Define a private field of the type of the event. This is done by the CSC compiler
4199 and we should be doing it too ;-)
4201 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
4202 More methods we use in code we generate.
4204 (multicast_delegate_type, delegate_type): Two separate types since the distinction
4207 (InitCoreTypes): Update accordingly for the above.
4209 * class.cs (Event.Emit): Generate code for default accessors that we provide
4211 (EmitDefaultMethod): Do the job in the above.
4213 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
4216 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4218 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
4219 builders even if we were missing one.
4221 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
4222 pass the Basename as our class name instead of the Name. The
4223 basename will be correctly composed for us.
4225 * parameter.cs (Paramters): Now takes a Location argument.
4227 * decl.cs (DeclSpace.LookupType): Removed convenience function and
4228 make all the code call directly LookupType in RootContext and take
4229 this chance to pass the Location information everywhere.
4231 * Everywhere: pass Location information.
4233 2001-12-19 Miguel de Icaza <miguel@ximian.com>
4235 * class.cs (Constructor.Define): Updated way of detecting the
4236 length of the parameters.
4238 (TypeContainer.DefineType): Use basename as the type name for
4241 (TypeContainer.Define): Do not recursively define types here, as
4242 definition is taken care in order by the RootContext.
4244 * tree.cs: Keep track of namespaces in a per-file basis.
4246 * parameter.cs (Parameter.ComputeSignature): Update to use
4249 (Parameters.GetSignature): ditto.
4251 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
4252 instead of a TypeContainer.
4254 (Interface.SemanticAnalysis): Use `this' instead of our parent to
4255 resolve names. Because we need to be resolve in our context, not
4258 * driver.cs: Implement response files.
4260 * class.cs (TypeContainer.DefineType): If we are defined, do not
4263 (Event.Emit): Emit the code for add/remove handlers.
4264 (Event.Define): Save the MethodBuilders for add/remove.
4266 * typemanager.cs: Use pair here too.
4268 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
4269 DictionaryEntry requires the first argument to be non-null.
4271 (enum_declaration): Compute full name for registering the
4274 (delegate_declaration): Instead of using
4275 formal_parameter_list, use opt_formal_parameter_list as the list
4278 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
4279 (EventParsing): New property that controls whether `add' and
4280 `remove' are returned as tokens or identifiers (for events);
4282 2001-12-19 Ravi Pratap <ravi@ximian.com>
4284 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
4285 use MyEventBuilder only and let it wrap the real builder for us.
4287 (MyEventBuilder): Revamp constructor etc.
4289 Implement all operations that we perform on EventBuilder in precisely the same
4292 (FindMembers): Update to use the EventBuilder member.
4294 (Event.Emit): Update accordingly.
4296 2001-12-18 Ravi Pratap <ravi@ximian.com>
4298 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
4299 by calling the appropriate methods.
4301 (GetCustomAttributes): Make stubs as they cannot possibly do anything
4304 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
4306 2001-12-17 Ravi Pratap <ravi@ximian.com>
4308 * delegate.cs (Delegate.Populate): Check that the return type
4309 and various parameters types are indeed accessible.
4311 * class.cs (Constructor.Define): Same here.
4313 (Field.Define): Ditto.
4315 (Event.Define): Ditto.
4317 (Operator.Define): Check that the underlying Method defined itself
4318 correctly - so it's MethodBuilder should not be null.
4320 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
4321 expression happens to be null.
4323 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
4324 members but as of now we don't seem to be able to do anything really useful with it.
4326 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
4327 not the EventBuilder.
4329 2001-12-18 Miguel de Icaza <miguel@ximian.com>
4331 * cs-tokenizer.cs: Add support for defines.
4332 Add support for #if, #elif, #else, #endif
4334 (eval_var): evaluates a variable.
4335 (eval): stubbed for evaluating functions.
4337 * cs-parser.jay: Pass the defines information
4339 * driver.cs: Add --define command line option.
4341 * decl.cs: Move MemberCore here.
4343 Make it the base class for DeclSpace. This allows us to catch and
4344 report 108 and 109 for everything now.
4346 * class.cs (TypeContainer.Define): Extract all the members
4347 before populating and emit the warning 108 (new keyword required
4348 to override) instead of having each member implement this.
4350 (MemberCore.Define): New abstract method, we will be using this in
4351 the warning reporting engine in Populate.
4353 (Operator.Define): Adjust to new MemberCore protocol.
4355 * const.cs (Const): This does not derive from Expression, it is a
4356 temporary object we use to create fields, it is a MemberCore.
4358 * class.cs (Method.Define): Allow the entry point to be in a
4361 * driver.cs: Rewrite the argument handler to clean it up a bit.
4363 * rootcontext.cs: Made it just an auxiliary namespace feature by
4364 making everything static.
4366 * driver.cs: Adapt code to use RootContext type name instead of
4369 * delegate.cs: Remove RootContext argument.
4371 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
4374 * class.cs (Event.Define): The lookup can fail.
4376 * cs-tokenizer.cs: Begin implementation of pre-procesor.
4378 * expression.cs: Resolve the this instance before invoking the code.
4380 2001-12-17 Miguel de Icaza <miguel@ximian.com>
4382 * cs-parser.jay: Add a production in element_access that allows
4383 the thing to become a "type" reference. This way we can parse
4384 things like "(string [])" as a type.
4386 Note that this still does not handle the more complex rules of
4390 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
4392 * ecore.cs: (CopyNewMethods): new utility function used to
4393 assemble the list of methods from running FindMembers.
4395 (MemberLookup): Rework FindMembers so that
4397 2001-12-16 Miguel de Icaza <miguel@ximian.com>
4399 * class.cs (TypeContainer): Remove Delegates who fail to be
4402 * delegate.cs (Populate): Verify that we dont get null return
4403 values. TODO: Check for AsAccessible.
4405 * cs-parser.jay: Use basename to emit error 574 (destructor should
4406 have the same name as container class), not the full name.
4408 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
4409 possible representation.
4411 Also implements integer type suffixes U and L.
4413 2001-12-15 Miguel de Icaza <miguel@ximian.com>
4415 * expression.cs (ArrayCreation.DoResolve): We need to do the
4416 argument resolution *always*.
4418 * decl.cs: Make this hold the namespace. Hold the root context as
4420 (LookupType): Move here.
4422 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
4424 * location.cs (Row, Name): Fixed the code, it was always returning
4425 references to the first file.
4427 * interface.cs: Register properties defined through interfaces.
4429 * driver.cs: Add support for globbing on the command line
4431 * class.cs (Field): Make it derive from MemberCore as well.
4434 2001-12-15 Ravi Pratap <ravi@ximian.com>
4436 * class.cs (Event::Define): Check that the type of the event is a delegate
4437 type else flag error #66.
4439 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
4442 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
4443 values of EntryPoint, CharSet etc etc.
4445 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
4447 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
4448 be null and we should ignore this. I am not sure if this is really clean. Apparently,
4449 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
4450 which needs this to do its work.
4452 * ../errors/cs0066.cs : Add.
4454 2001-12-14 Miguel de Icaza <miguel@ximian.com>
4456 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
4459 * class.cs: (MethodSignature.MethodSignature): Removed hack that
4460 clears out the parameters field.
4461 (MemberSignatureCompare): Cleanup
4463 (MemberCore): New base class used to share code between MethodCore
4466 (RegisterRequiredImplementations) BindingFlags.Public requires
4467 either BindingFlags.Instace or Static. Use instance here.
4469 (Property): Refactored code to cope better with the full spec.
4471 * parameter.cs (GetParameterInfo): Return an empty array instead
4474 * class.cs (Property): Abstract or extern properties have no bodies.
4476 * parameter.cs (GetParameterInfo): return a zero-sized array.
4478 * class.cs (TypeContainer.MethodModifiersValid): Move all the
4479 method modifier validation to the typecontainer so we can reuse
4482 (MethodCore.ParameterTypes): return an empty sized array of types.
4484 (Property.Define): Test property modifier validity.
4486 Add tests for sealed/override too.
4488 (Method.Emit): abstract or extern methods have no bodies.
4490 2001-12-14 Ravi Pratap <ravi@ximian.com>
4492 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive

4497 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
4499 (ArrayCreation::MakeByteBlob): Handle floats and doubles.

4505 * class.cs (MakeKey): Kill routine.
4507 * class.cs (TypeContainer.Define): Correctly define explicit
4508 method implementations (they require the full interface name plus
4511 * typemanager.cs: Deply the PtrHashtable here and stop using the
4512 lame keys. Things work so much better.
4514 This of course broke everyone who depended on `RegisterMethod' to
4515 do the `test for existance' test. This has to be done elsewhere.
4517 * support.cs (PtrHashtable): A hashtable that avoid comparing with
4518 the object stupid Equals method (because, that like fails all over
4519 the place). We still do not use it.
4521 * class.cs (TypeContainer.SetRequiredInterface,
4522 TypeContainer.RequireMethods): Killed these two routines and moved
4523 all the functionality to RegisterRequiredImplementations.
4525 (TypeContainer.RegisterRequiredImplementations): This routine now
4526 registers all the implementations required in an array for the
4527 interfaces and abstract methods. We use an array of structures
4528 which can be computed ahead of time to reduce memory usage and we
4529 also assume that lookups are cheap as most classes will not
4530 implement too many interfaces.
4532 We also avoid creating too many MethodSignatures.
4534 (TypeContainer.IsInterfaceMethod): Update and optionally does not
4535 clear the "pending" bit if we find that there are problems with
4538 (TypeContainer.VerifyPendingMethods): Update to report errors of
4539 methods that look like implementations but are not.
4541 (TypeContainer.Define): Add support for explicit interface method
4544 2001-12-12 Miguel de Icaza <miguel@ximian.com>
4546 * typemanager.cs: Keep track of the parameters here instead of
4547 being a feature of the TypeContainer.
4549 * class.cs: Drop the registration of parameters here, as
4550 InterfaceMethods are also interface declarations.
4552 * delegate.cs: Register methods with the TypeManager not only with
4553 the TypeContainer. This code was buggy.
4555 * interface.cs: Full registation here.
4557 2001-12-11 Miguel de Icaza <miguel@ximian.com>
4559 * expression.cs: Remove reducer for binary expressions, it can not
4562 * const.cs: Put here the code that used to go into constant.cs
4564 * constant.cs: Put here the code for constants, this is a new base

4574 (Return.Emit): Instead of emitting a return, jump to the end of
4577 * codegen.cs (EmitContext): ReturnValue, ReturnLabel: new
4578 LocalBuilder to store the result of the function. ReturnLabel is
4579 the target where we jump.
4582 2001-12-09 Radek Doulik <rodo@ximian.com>
4584 * cs-parser.jay: remember alias in current namespace

4589 * class.cs (LookupAlias): lookup alias in my_namespace
4591 * namespace.cs (UsingAlias): add alias, namespace_or_type pair to
4593 (LookupAlias): lookup alias in this and if needed in parent
4596 2001-12-08 Miguel de Icaza <miguel@ximian.com>
4600 * rootcontext.cs: (ModuleBuilder) Made static, first step into
4601 making things static. I need this to avoid passing the
4602 TypeContainer when calling ParameterType.
4604 * support.cs (InternalParameters.ParameterType): Remove ugly hack
4605 that did string manipulation to compute the type and then call
4606 GetType. Use Parameter.ParameterType instead.
4608 * cs-tokenizer.cs: Consume the suffix for floating values.
4610 * expression.cs (ParameterReference): figure out whether this is a
4611 reference parameter or not. Kill an extra variable by computing
4612 the arg_idx during emission.
4614 * parameter.cs (Parameters.GetParameterInfo): New overloaded
4615 function that returns whether a parameter is an out/ref value or not.
4617 (Parameter.ParameterType): The type of the parameter (base,

4628 * statement.cs (Using.EmitLocalVariableDecls): Split the
4629 localvariable handling of the using statement.
4631 (Block.EmitMeta): Keep track of variable count across blocks. We
4632 were reusing slots on separate branches of blocks.
4634 (Try.Emit): Emit the general code block, we were not emitting it.
4636 Check the type of the declaration to be an IDisposable or
4637 something that can be implicity converted to it.
4639 Emit conversions if required.
4641 * ecore.cs (EmptyExpression): New utility class.
4642 (Expression.ImplicitConversionExists): New utility function.
4644 2001-12-06 Miguel de Icaza <miguel@ximian.com>
4646 * statement.cs (Using): Implement.
4648 * expression.cs (LocalVariableReference): Support read only variables.
4650 * statement.cs: Remove the explicit emit for the Leave opcode.

4655 * ecore.cs (ConvCast): new class used to encapsulate the various
4656 explicit integer conversions that works in both checked and
4659 (Expression.ConvertNumericExplicit): Use new ConvCast class to
4660 properly generate the overflow opcodes.
4662 2001-12-04 Miguel de Icaza <miguel@ximian.com>
4664 * statement.cs: The correct type for the EmptyExpression is the
4665 element_type, not the variable type. Ravi pointed this out.
4667 2001-12-04 Ravi Pratap <ravi@ximian.com>
4669 * class.cs (Method::Define): Handle PInvoke methods specially
4670 by using DefinePInvokeMethod instead of the usual one.
4672 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
4673 above to do the task of extracting information and defining the method.
4675 2001-12-04 Ravi Pratap <ravi@ximian.com>
4677 * expression.cs (ArrayCreation::EmitStaticInitializers): Get rid

4699 * statement.cs (GotoDefault), cs-parser.jay: Implement `goto
4702 (Foreach.Emit): Foreach on arrays was not setting
4703 up the loop variables (for break/continue).
4705 (GotoCase): Semi-implented.
4707 2001-12-03 Ravi Pratap <ravi@ximian.com>

4757 As that share bits of the implementation. Is returns a boolean,
4758 while As returns the Type that is being probed.
4760 2001-12-01 Ravi Pratap <ravi@ximian.com>
4762 * enum.cs (LookupEnumValue): Re-write various bits, return an object value
4763 instead of a Literal - much easier.
4765 (EnumInTransit): Remove - utterly useless :-)
4767 (Populate): Re-write bits - remove duplicate code etc. The code is much neater now.
4769 * expression.cs (MemberLookup): Cope with user-defined enums when they are in transit.

4864 directly from ArrayData now.
4866 (ExpectInitializers): Keep track of whether initializers are mandatory
4869 (Bounds): Make it a hashtable to prevent the same dimension being
4870 recorded for every element in that dimension.

4919 2001-11-22 Miguel de Icaza <miguel@ximian.com>
4921 * statement.cs (If.Emit): Fix a bug that generated incorrect code

4932 allowed a limited set of types to be handled. Now we take a
4933 unary_expression and we resolve to a type during semantic
4936 Use the grammar productions from Rhys to handle casts (this is
4937 not complete like Rhys syntax yet, we fail to handle that corner
4938 case that C# has regarding (-x), but we will get there.

4985 (Expression.ImplicitNumericConversion): Oops, forgot to test for

4989 2001-11-21 Miguel de Icaza <miguel@ximian.com>
4991 * cs-parser.jay (for_statement): Reworked the way For works: now
4992 we declare manually any variables that are introduced in
4993 for_initializer to solve the problem of having out-of-band code
4994 emition (that is what got for broken).
4996 (declaration_statement): Perform the actual variable declaration
4997 that used to be done in local_variable_declaration here.
4999 (local_variable_declaration): Do not declare anything, just pass
5000 the information on a DictionaryEntry

5067 we can use this elsewhere.
5069 * statement.cs: Finish implementation of foreach for single
5072 * cs-parser.jay: Use an out-of-band stack to pass information
5073 around, I wonder why I need this.
5075 foreach_block: Make the new foreach_block the current_block.
5077 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
5078 function used to return a static Parameters structure. Used for
5079 empty parameters, as those are created very frequently.
5081 * cs-parser.jay, class.cs: Use GetEmptyReadOnlyParameters
5083 2001-11-15 Ravi Pratap <ravi@ximian.com>
5085 * interface.cs : Default modifier is private, not public. The

5088 2001-11-15 Ravi Pratap <ravi@ximian.com>
5090 * support.cs (ReflectionParameters): Fix logic to determine

5147 * class.cs (Method.Emit): Clean up.
5149 * expression.cs (Argument.Resolve): Take another argument: the
5150 location where this argument is used. Notice that this is not
5151 part of the "Argument" class as to reduce the size of the
5152 structure (we know the approximate location anyways).
5154 Test if the argument is a variable-reference, if not, then
5155 complain with a 206.
5157 (Argument.Emit): Emit addresses of variables.
5159 (Argument.FullDesc): Simplify.
5161 (Invocation.DoResolve): Update for Argument.Resolve.

5194 * expression.cs (UnaryMutator): New class, used to handle ++ and
5195 -- separatedly from the other unary operators. Cleans up the
5196 code, and kills the ExpressionStatement dependency in Unary.

5912 the builders for the 4 members of a delegate type :-)
5914 (Populate): Define the BeginInvoke and EndInvoke methods on the delegate
5917 * expression.cs (New::DoResolve): Implement guts for delegate creation.
5919 * ../errors/errors.txt : Update for an error (-11) which only we catch :-)
5921 2001-10-15 Miguel de Icaza <miguel@ximian.com>

5932 * codegen.cs (EmitContext::LoopEnd, EmitContext::LoopBegin): New
5933 properties that track the label for the current loop (begin of the
5934 loop and end of the loop).
5936 2001-10-15 Ravi Pratap <ravi@ximian.com>
5938 * delegate.cs (Emit): Get rid of it as there doesn't seem to be any ostensible
5939 use of emitting anything at all.
5941 * class.cs, rootcontext.cs : Get rid of calls to the same.
5943 * delegate.cs (DefineDelegate): Make sure the class we define is also sealed.
5945 (Populate): Define the constructor correctly and set the implementation
5948 * typemanager.cs (delegate_types): New hashtable to hold delegates that

5953 (IsDelegateType): Implement helper method.
5955 * delegate.cs (DefineDelegate): Use AddDelegateType instead of AddUserType.
5957 * expression.cs (New::DoResolve): Check if we are trying to instantiate a delegate type
5958 and accordingly handle it.
5960 * delegate.cs (Populate): Take TypeContainer argument.
5961 Implement bits to define the Invoke method. However, I still haven't figured out
5962 how to take care of the native int bit :-(
5964 * cs-parser.jay (delegate_declaration): Fixed the bug that I had introduced :-)
5965 Qualify the name of the delegate, not its return type !
5967 * expression.cs (ImplicitReferenceConversion): Implement guts of implicit array
5970 (StandardConversionExists): Checking for array types turns out to be recursive.
5972 (ConvertReferenceExplicit): Implement array conversion.
5974 (ExplicitReferenceConversionExists): New method to determine precisely that :-)
5976 2001-10-12 Ravi Pratap <ravi@ximian.com>
5978 * cs-parser.jay (delegate_declaration): Store the fully qualified
5979 name as it is a type declaration.
5981 * delegate.cs (ReturnType, Name): Rename members to these. Make them
5984 (DefineDelegate): Renamed from Define. Does the same thing essentially,
5985 as TypeContainer::DefineType.
5987 (Populate): Method in which all the definition of the various methods (Invoke)
5990 (Emit): Emit any code, if necessary. I am not sure about this really, but let's
5993 (CloseDelegate): Finally creates the delegate.
5995 * class.cs (TypeContainer::DefineType): Update to define delegates.
5996 (Populate, Emit and CloseType): Do the same thing here too.
5998 * rootcontext.cs (ResolveTree, PopulateTypes, EmitCode, CloseTypes): Include
5999 delegates in all these operations.
6001 2001-10-14 Miguel de Icaza <miguel@ximian.com>
6003 * expression.cs: LocalTemporary: a new expression used to
6004 reference a temporary that has been created.
6006 * assign.cs: Handle PropertyAccess back here, so that we can
6007 provide the proper semantic access to properties.
6009 * expression.cs (Expression::ConvertReferenceExplicit): Implement
6010 a few more explicit conversions.
6012 * modifiers.cs: `NEW' modifier maps to HideBySig.
6014 * expression.cs (PropertyExpr): Make this into an
6015 ExpressionStatement, and support the EmitStatement code path.
6017 Perform get/set error checking, clean up the interface.
6019 * assign.cs: recognize PropertyExprs as targets, and if so, turn
6020 them into toplevel access objects.

6024 * expression.cs: PropertyExpr::PropertyExpr: use work around the
6027 * typemanager.cs: Keep track here of our PropertyBuilders again to
6028 work around lameness in SRE.
6030 2001-10-11 Miguel de Icaza <miguel@ximian.com>
6032 * expression.cs (LValue::LValueResolve): New method in the
6033 interface, used to perform a second resolution pass for LValues.
6035 (This::DoResolve): Catch the use of this in static methods.
6037 (This::LValueResolve): Implement.
6039 (This::Store): Remove warning, assigning to `this' in structures
6042 (Invocation::Emit): Deal with invocation of
6043 methods on value types. We need to pass the address to structure
6044 methods rather than the object itself. (The equivalent code to
6045 emit "this" for structures leaves the entire structure on the
6046 stack instead of a pointer to it).
6048 (ParameterReference::DoResolve): Compute the real index for the
6049 argument based on whether the method takes or not a `this' pointer
6050 (ie, the method is static).
6052 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store
6053 value types returned from functions when we need to invoke a
6054 method on the sturcture.
6057 2001-10-11 Ravi Pratap <ravi@ximian.com>
6059 * class.cs (TypeContainer::DefineType): Method to actually do the business of
6060 defining the type in the Modulebuilder or Typebuilder. This is to take
6061 care of nested types which need to be defined on the TypeBuilder using
6064 (TypeContainer::GetClassBases): Implement. Essentially the code from the
6065 methods in RootContext, only ported to be part of TypeContainer.
6067 (TypeContainer::GetInterfaceOrClass): Ditto.
6069 (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
6071 * interface.cs (Interface::DefineInterface): New method. Does exactly
6072 what RootContext.CreateInterface did earlier, only it takes care of nested types
6075 (Interface::GetInterfaces): Move from RootContext here and port.
6077 (Interface::GetInterfaceByName): Same here.
6079 * rootcontext.cs (ResolveTree): Re-write.

6083 * class.cs (TypeContainer::Populate): Populate nested types too.
6084 (TypeContainer::Emit): Emit nested members too.
6086 * typemanager.cs (AddUserType): Do not make use of the FullName property,
6087 instead just use the name argument passed in as it is already fully
6090 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
6091 to TypeContainer mapping to see if a type is user-defined.
6093 * class.cs (TypeContainer::CloseType): Implement.
6095 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
6096 the default constructor.
6098 (TypeContainer::Populate): Fix minor bug which led to creating default constructors
6101 (Constructor::IsDefault): Fix up logic to determine if it is the default constructor
6103 * interface.cs (CloseType): Create the type here.
6105 * rootcontext.cs (CloseTypes): Re-write to recursively close types by running through
6108 Remove all the methods which are now in TypeContainer.
6110 2001-10-10 Ravi Pratap <ravi@ximian.com>
6112 * delegate.cs (Define): Re-write bits to define the delegate
6115 2001-10-10 Miguel de Icaza <miguel@ximian.com>
6117 * makefile: Renamed the compiler to `mcs.exe' instead of compiler.exe
6119 * expression.cs (ImplicitReferenceConversion): handle null as well
6120 as a source to convert to any reference type.
6122 * statement.cs (Return): Perform any implicit conversions to
6123 expected return type.
6125 Validate use of return statement.
6127 * codegen.cs (EmitContext): Pass the expected return type here.
6129 * class.cs (Method, Constructor, Property): Pass expected return
6130 type to EmitContext.
6132 2001-10-09 Miguel de Icaza <miguel@ximian.com>
6134 * expression.cs: Make DoResolve take an EmitContext instead of a
6137 Replaced `l' and `location' for `loc', for consistency.
6139 (Error, Warning): Remove unneeded Tc argument.
6141 * assign.cs, literal.cs, constant.cs: Update to new calling
6144 * codegen.cs: EmitContext now contains a flag indicating whether
6145 code is being generated in a static method or not.
6147 * cs-parser.jay: DecomposeQI, new function that replaces the old
6148 QualifiedIdentifier. Now we always decompose the assembled
6149 strings from qualified_identifier productions into a group of
6152 2001-10-08 Miguel de Icaza <miguel@ximian.com>
6154 * rootcontext.cs: Deal with field-less struct types correctly now
6155 by passing the size option to Define Type.
6157 * class.cs: Removed hack that created one static field.
6159 2001-10-07 Miguel de Icaza <miguel@ximian.com>
6161 * statement.cs: Moved most of the code generation here.
6163 2001-10-09 Ravi Pratap <ravi@ximian.com>
6165 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
6168 (ElementAccess): Remove useless bits for now - keep checks as the spec
6171 2001-10-08 Ravi Pratap <ravi@ximian.com>
6173 * expression.cs (ElementAccess::DoResolve): Remove my crap code
6174 and start performing checks according to the spec.
6176 2001-10-07 Ravi Pratap <ravi@ximian.com>
6178 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
6179 rank_specifiers instead.
6181 (rank_specifiers): Change the order in which the rank specifiers are stored
6183 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
6185 * expression.cs (ElementAccess): Implement the LValue interface too.
6187 2001-10-06 Ravi Pratap <ravi@ximian.com>
6189 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
6190 except that user defined conversions are not included.
6192 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
6193 perform the conversion of the return type, if necessary.
6195 (New::DoResolve): Check whether we are creating an array or an object
6196 and accordingly do the needful.
6198 (New::Emit): Same here.
6200 (New::DoResolve): Implement guts of array creation.
6202 (New::FormLookupType): Helper function.
6204 2001-10-07 Miguel de Icaza <miguel@ximian.com>
6206 * codegen.cs: Removed most of the code generation here, and move the
6207 corresponding code generation bits to the statement classes.
6209 Added support for try/catch/finalize and throw.
6211 * cs-parser.jay: Added support for try/catch/finalize.
6213 * class.cs: Catch static methods having the flags override,
6214 virtual or abstract.
6216 * expression.cs (UserCast): This user cast was not really doing
6217 what it was supposed to do. Which is to be born in fully resolved
6218 state. Parts of the resolution were being performed at Emit time!
6222 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6224 * expression.cs: Implicity convert the result from UserCast.
6226 2001-10-05 Ravi Pratap <ravi@ximian.com>
6228 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
6229 prevented it from working correctly.
6231 (ConvertExplicit): Make the first try, a call to ConvertImplicitStandard, not
6232 merely ConvertImplicit.
6234 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6236 * typemanager.cs: Make the LookupTypeContainer function static,
6237 and not per-instance.
6239 * class.cs: Make static FindMembers (the one that takes a Type
6242 * codegen.cs: Add EmitForeach here.
6244 * cs-parser.jay: Make foreach a toplevel object instead of the
6245 inline expansion, as we need to perform semantic analysis on it.
6247 2001-10-05 Ravi Pratap <ravi@ximian.com>
6249 * expression.cs (Expression::ImplicitUserConversion): Rename to
6250 UserDefinedConversion.
6252 (Expression::UserDefinedConversion): Take an extra argument specifying
6253 whether we look for explicit user conversions too.
6255 (Expression::ImplicitUserConversion): Make it a call to UserDefinedConversion.

6264 * expression.cs (Cast): Record location info.
6266 (Expression::ConvertExplicit): Take location argument.
6268 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
6269 to determine if we are doing explicit conversions.
6271 (UserCast::Emit): Update accordingly.
6273 (Expression::ConvertExplicit): Report an error if everything fails.
6275 * ../errors/cs0030.cs : Add.
6277 2001-10-04 Miguel de Icaza <miguel@ximian.com>
6279 * modifiers.cs: If the ABSTRACT keyword is present, also set the
6280 virtual and newslot bits.
6282 * class.cs (TypeContainer::RegisterRequiredImplementations):
6283 Record methods we need.
6285 (TypeContainer::MakeKey): Helper function to make keys for
6286 MethodBases, since the Methodbase key is useless.
6288 (TypeContainer::Populate): Call RegisterRequiredImplementations
6289 before defining the methods.
6291 Create a mapping for method_builders_to_methods ahead of time
6292 instead of inside a tight loop.
6294 (::RequireMethods): Accept an object as the data to set into the
6295 hashtable so we can report interface vs abstract method mismatch.
6297 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6299 * report.cs: Make all of it static.
6301 * rootcontext.cs: Drop object_type and value_type computations, as
6302 we have those in the TypeManager anyways.
6304 Drop report instance variable too, now it is a global.
6306 * driver.cs: Use try/catch on command line handling.
6308 Add --probe option to debug the error reporting system with a test
6311 * report.cs: Add support for exiting program when a probe
6312 condition is reached.
6314 2001-10-03 Ravi Pratap <ravi@ximian.com>
6316 * expression.cs (Binary::DoNumericPromotions): Fix the case when
6317 we do a forcible conversion regardless of type, to check if
6318 ForceConversion returns a null.
6320 (Binary::error19): Use location to report error.
6322 (Unary::error23): Use location here too.
6324 * ../errors/cs0019.cs : Check in.
6326 * ../errors/cs0023.cs : Check in.
6328 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
6329 case of a non-null MethodInfo object with a length of 0 !
6331 (Binary::ResolveOperator): Flag error if overload resolution fails to find
6332 an applicable member - according to the spec :-)
6333 Also fix logic to find members in base types.
6335 (Unary::ResolveOperator): Same here.
6337 (Unary::report23): Change name to error23 and make first argument a TypeContainer
6338 as I was getting thoroughly confused between this and error19 :-)
6340 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
6341 (::FindMostEncompassedType): Implement.
6342 (::FindMostEncompassingType): Implement.
6343 (::StandardConversionExists): Implement.
6345 (UserImplicitCast): Re-vamp. We now need info about most specific
6346 source and target types so that we can do the necessary conversions.
6348 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
6349 mathematical union with no duplicates.
6351 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6353 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
6354 in order from base classes to child classes, so that we can in
6355 child classes look up in our parent for method names and
6356 attributes (required for handling abstract, virtual, new, override
6357 constructs: we need to instrospect our base class, and if we dont
6358 populate the classes in order, the introspection might be
6359 incorrect. For example, a method could query its parent before
6360 the parent has any methods and would determine that the parent has
6361 no abstract methods (while it could have had them)).
6363 (RootContext::CreateType): Record the order in which we define the
6366 2001-10-02 Miguel de Icaza <miguel@ximian.com>
6368 * class.cs (TypeContainer::Populate): Also method definitions can
6369 fail now, keep track of this.
6371 (TypeContainer::FindMembers): Implement support for
6372 DeclaredOnly/noDeclaredOnly flag.
6374 (Constructor::Emit) Return the ConstructorBuilder.
6376 (Method::Emit) Return the MethodBuilder.
6377 Check for abstract or virtual methods to be public.
6379 * rootcontext.cs (RootContext::CreateType): Register all the
6380 abstract methods required for the class to be complete and the
6381 interface methods that must be implemented.
6383 * cs-parser.jay: Report error 501 (method requires body if it is
6384 not marked abstract or extern).
6386 * expression.cs (TypeOf::Emit): Implement.
6388 * typemanager.cs: runtime_handle_type, new global type.
6390 * class.cs (Property::Emit): Generate code for properties.
6392 2001-10-02 Ravi Pratap <ravi@ximian.com>
6394 * expression.cs (Unary::ResolveOperator): Find operators on base type
6395 too - we now conform exactly to the spec.
6397 (Binary::ResolveOperator): Same here.
6399 * class.cs (Operator::Define): Fix minor quirk in the tests.
6401 * ../errors/cs0215.cs : Added.
6403 * ../errors/cs0556.cs : Added.
6405 * ../errors/cs0555.cs : Added.
6407 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6409 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
6410 single integer which is really efficient
6412 2001-10-01 Ravi Pratap <ravi@ximian.com>
6414 * expression.cs (Expression::ImplicitUserConversion): Use location
6415 even in the case when we are examining True operators.
6417 * class.cs (Operator::Define): Perform extensive checks to conform
6418 with the rules for operator overloading in the spec.
6420 * expression.cs (Expression::ImplicitReferenceConversion): Implement
6421 some of the other conversions mentioned in the spec.
6423 * typemanager.cs (array_type): New static member for the System.Array built-in
6426 (cloneable_interface): For System.ICloneable interface.
6428 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
6429 we start resolving the tree and populating types.
6431 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
6433 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6435 * expression.cs (Expression::ExprClassFromMemberInfo,
6436 Expression::Literalize): Create literal expressions from
6437 FieldInfos which are literals.
6439 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
6440 type casts, because they were wrong. The test suite in tests
6443 (ImplicitNumericConversion): ushort to ulong requires a widening
6446 Int32 constant to long requires widening cast as well.
6448 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
6449 for integers because the type on the stack is not i4.
6451 2001-09-30 Miguel de Icaza <miguel@ximian.com>
6453 * expression.cs (report118): require location argument.
6455 * parameter.cs: Do not dereference potential null value.
6457 * class.cs: Catch methods that lack the `new' keyword when
6458 overriding a name. Report warnings when `new' is used without
6459 anything being there to override.
6461 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
6463 * class.cs: Only add constructor to hashtable if it is non-null
6464 (as now constructors can fail on define).
6466 (TypeManager, Class, Struct): Take location arguments.
6468 Catch field instance initialization in structs as errors.
6470 accepting_filter: a new filter for FindMembers that is static so
6471 that we dont create an instance per invocation.
6473 (Constructor::Define): Catch errors where a struct constructor is
6476 * cs-parser.jay: Pass location information for various new
6479 * delegate.cs (Delegate): take a location argument.
6481 * driver.cs: Do not call EmitCode if there were problesm in the
6482 Definition of the types, as many Builders wont be there.
6484 * decl.cs (Decl::Decl): Require a location argument.
6486 * cs-tokenizer.cs: Handle properly hex constants that can not fit
6487 into integers, and find the most appropiate integer for it.
6489 * literal.cs: Implement ULongLiteral.
6491 * rootcontext.cs: Provide better information about the location of
6492 failure when CreateType fails.
6494 2001-09-29 Miguel de Icaza <miguel@ximian.com>
6496 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
6499 * expression.cs (Binary::CheckShiftArguments): Add missing type
6501 (Binary::ResolveOperator): Add type to the logical and and logical
6502 or, Bitwise And/Or and Exclusive Or code paths, it was missing
6505 (Binary::DoNumericPromotions): In the case where either argument
6506 is ulong (and most signed types combined with ulong cause an
6507 error) perform implicit integer constant conversions as well.
6509 2001-09-28 Miguel de Icaza <miguel@ximian.com>
6511 * expression.cs (UserImplicitCast): Method should always be
6513 (Invocation::BetterConversion): Simplified test for IntLiteral.
6515 (Expression::ImplicitNumericConversion): Split this routine out.
6516 Put the code that performs implicit constant integer conversions
6519 (Expression::Resolve): Become a wrapper around DoResolve so we can
6520 check eclass and type being set after resolve.
6522 (Invocation::Badness): Remove this dead function
6524 (Binary::ResolveOperator): Do not compute the expensive argumnets
6525 unless we have a union for it.
6527 (Probe::Emit): Is needs to do an isinst and then
6528 compare against null.
6530 (::CanConvert): Added Location argument. If the Location argument
6531 is null (Location.Null), then we do not report errors. This is
6532 used by the `probe' mechanism of the Explicit conversion. We do
6533 not want to generate an error for something that the user
6534 explicitly requested to be casted. But the pipeline for an
6535 explicit cast first tests for potential implicit casts.
6537 So for now, if the Location is null, it means `Probe only' to
6538 avoid adding another argument. Might have to revise this
6541 (ClassCast): New class used to type cast objects into arbitrary
6542 classes (used in Explicit Reference Conversions).
6544 Implement `as' as well.
6546 Reverted all the patches from Ravi below: they were broken:
6548 * The use of `level' as a mechanism to stop recursive
6549 invocations is wrong. That was there just to catch the
6550 bug with a strack trace but not as a way of addressing
6553 To fix the problem we have to *understand* what is going
6554 on and the interactions and come up with a plan, not
6555 just get things going.
6557 * The use of the type conversion cache that I proposed
6558 last night had an open topic: How does this work across
6559 protection domains. A user defined conversion might not
6560 be public in the location where we are applying the
6561 conversion, a different conversion might be selected
6562 (ie, private A->B (better) but public B->A (worse),
6563 inside A, A->B applies, but outside it, B->A will
6566 * On top of that (ie, even if the above is solved),
6567 conversions in a cache need to be abstract. Ie, `To
6568 convert from an Int to a Short use an OpcodeCast', not
6569 `To convert from an Int to a Short use the OpcodeCast on
6570 the variable 5' (which is what this patch was doing).
6572 2001-09-28 Ravi Pratap <ravi@ximian.com>
6574 * expression.cs (Invocation::ConversionExists): Re-write to use
6575 the conversion cache
6577 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
6578 cache all conversions done, not just user-defined ones.
6580 (Invocation::BetterConversion): The real culprit. Use ConversionExists
6581 to determine if a conversion exists instead of acutually trying to
6582 perform the conversion. It's faster too.
6584 (Expression::ConvertExplicit): Modify to use ConversionExists to check
6585 and only then attempt the implicit conversion.
6587 2001-09-28 Ravi Pratap <ravi@ximian.com>
6589 * expression.cs (ConvertImplicit): Use a cache for conversions
6590 already found. Check level of recursion and bail out if necessary.

6609 Fix the order in which implicit conversions are
6612 The previous fixed dropped support for boxed conversions (adding a
6613 test to the test suite now)
6615 (UserImplicitCast::CanConvert): Remove test for source being null,
6616 that code is broken. We should not feed a null to begin with, if
6617 we do, then we should track the bug where the problem originates
6618 and not try to cover it up here.
6620 Return a resolved expression of type UserImplicitCast on success
6621 rather than true/false. Ravi: this is what I was talking about,
6622 the pattern is to use a static method as a "constructor" for
6625 Also, do not create arguments until the very last minute,
6626 otherwise we always create the arguments even for lookups that
6627 will never be performed.
6629 (UserImplicitCast::Resolve): Eliminate, objects of type
6630 UserImplicitCast are born in a fully resolved state.
6632 * typemanager.cs (InitCoreTypes): Init also value_type
6635 * expression.cs (Cast::Resolve): First resolve the child expression.
6637 (LValue): Add new method AddressOf to be used by
6640 Change the argument of Store to take an EmitContext instead of an
6641 ILGenerator, because things like FieldExpr need to be able to call
6642 their children expression to generate the instance code.
6644 (Expression::Error, Expression::Warning): Sugar functions for
6647 (Expression::MemberLookup): Accept a TypeContainer instead of a
6648 Report as the first argument.
6650 (Expression::ResolvePrimary): Killed. I still want to improve
6651 this as currently the code is just not right.
6653 (Expression::ResolveMemberAccess): Simplify, but it is still
6656 (Unary::Resolve): Catch errors in AddressOf operators.
6658 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
6659 index to a byte for the short-version, or the compiler will choose
6660 the wrong Emit call, which generates the wrong data.
6662 (ParameterReference::Emit, ::Store): same.
6664 (FieldExpr::AddressOf): Implement.
6666 * typemanager.cs: TypeManager: made public variable instead of
6669 * driver.cs: document --fatal.

6672 Error and Warning classes.
6674 * cs-parser.jay (member_access): Turn built-in access to types
6675 into a normal simplename
6677 2001-09-27 Ravi Pratap <ravi@ximian.com>

6680 with q being null, since this was introducing a bug.
6682 * expression.cs (ConvertImplicit): Do built-in conversions first.
6684 2001-09-27 Ravi Pratap <ravi@ximian.com>
6686 * expression.cs (UserImplicitCast::Resolve): Fix bug.
6688 2001-09-27 Ravi Pratap <ravi@ximian.com>
6690 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
6691 I had introduced long ago (what's new ?).
6693 * expression.cs (UserImplicitCast::CanConvert): Static method to do
6694 the work of all the checking.
6695 (ConvertImplicit): Call CanConvert and only then create object if necessary.
6696 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
6698 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
6699 that is the right way.
6701 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
6702 overloading resolution. Use everywhere instead of cutting and pasting code.
6704 (Binary::ResolveOperator): Use MakeUnionSet.
6706 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
6707 we have to convert to bool types. Not complete yet.
6709 2001-09-27 Miguel de Icaza <miguel@ximian.com>
6711 * typemanager.cs (TypeManager::CSharpName): support ushort.
6713 * expression.cs (Expression::TryImplicitIntConversion): Attempts
6714 to provide an expression that performsn an implicit constant int
6715 conversion (section 6.1.6).

6717 implicit constant expression conversions.
6719 (Expression::ConvertNumericExplicit): Finished.
6721 (Invocation::Emit): If InstanceExpression is null, then it means
6722 that we perform a call on this.
6724 2001-09-26 Miguel de Icaza <miguel@ximian.com>
6726 * expression.cs (Unary::Emit): Remove some dead code.
6727 (Probe): Implement Resolve and Emit for `is'.
6728 (Expression::ConvertImplicitRequired): Attempt to do constant
6729 expression conversions here. Maybe should be moved to
6730 ConvertImplicit, but I am not sure.
6731 (Expression::ImplicitLongConstantConversionPossible,
6732 Expression::ImplicitIntConstantConversionPossible): New functions
6733 that tell whether is it possible to apply an implicit constant
6734 expression conversion.

6747 ones that the spec expects (as we are just stringizing the
6750 * expression.cs (Unary::ResolveOperator): Fix bug: Use
6751 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
6752 previous usage did only work for our methods.
6753 (Expression::ConvertImplicit): Handle decimal implicit numeric
6754 conversions as well.
6755 (Expression::InternalTypeConstructor): Used to invoke constructors
6756 on internal types for default promotions.
6758 (Unary::Emit): Implement special handling for the pre/post
6759 increment/decrement for overloaded operators, as they need to have
6760 the same semantics as the other operators.
6762 (Binary::ResolveOperator): ditto.

6780 * assign.cs (Assign): Make it inherit from ExpressionStatement.
6782 * expression.cs (ExpressionStatement): New base class used for
6783 expressions that can appear in statements, so that we can provide
6784 an alternate path to generate expression that do not leave a value
6787 (Expression::Emit, and all the derivatives): We no longer return
6788 whether a value is left on the stack or not. Every expression
6789 after being emitted leaves a single value on the stack.

6792 facilties of ExpressionStatement if possible.
6794 * cs-parser.jay: Update statement_expression.

6819 * assign.cs: track location.
6820 (Resolve): Use implicit conversions on assignment.

6863 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
6864 Also take an additional TypeContainer argument.

6885 * typemanager.cs: declare and load enum_type, delegate_type and
6888 * expression.cs (Expression::Emit): Now emit returns a value that
6889 tells whether a value is left on the stack or not. This strategy
6890 might be reveted tomorrow with a mechanism that would address
6891 multiple assignments.
6892 (Expression::report118): Utility routine to report mismatches on
6895 (Unary::Report23): Report impossible type/operator combination

6949 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
6950 Use a basename for those routines because .NET does not like paths

6965 expressions (otherwise they are Unary {Literal}).
6966 (Invocation::Badness): Take into account `Implicit constant
6967 expression conversions'.

6970 (IntLiteral): export the `Value' of the intliteral.

6987 * expression.cs (Unary::Resolve): Implement.
6988 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
6989 operators are found instead of making noise ;-)
6990 (Unary::ResolveOperator): New method to do precisely the same thing which
6991 Binary::ResolveOperator does for Binary expressions.

7004 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
7005 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

7018 (FieldExpr::Emit): Implement.
7020 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
7021 the last instruction contains a return opcode to avoid generating
7022 the last `ret' instruction (this generates correct code, and it is
7023 nice to pass the peverify output).
7025 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
7026 initializer for static and instance variables.
7027 (Constructor::Emit): Allow initializer to be null in the case of
7028 static constructors. Only emit initializer for instance

7049 * class.cs: Do not emit parent class initializers for static
7050 constructors, that should be flagged as an error.
7052 2001-09-18 Ravi Pratap <ravi@ximian.com>
7054 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
7055 Move back code into TypeContainer::Populate.

7084 (Expression::MemberLookup): Provide a version that allows to
7085 specify the MemberTypes and BindingFlags.
7087 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
7088 so it was not fetching variable information from outer blocks.
7090 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
7091 Beforefieldinit as it was buggy.
7093 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
7096 * class.cs (Constructor::Emit): Only emit if block is not null.
7097 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
7098 deal with this by semantically definining it as if the user had
7101 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
7102 constructors as we now "emit" them at a higher level.

7105 default constructors if none was provided.
7107 (ConstructorInitializer): Add methods Resolve and Emit.
7109 * expression.cs: Cast to ConstructorInfo instead of MethodInfo

7139 * class.cs (Operator::Emit): Implement.
7140 (TypeContainer::Emit): Emit the operators we have too.
7142 * expression.cs (Binary::Emit): Update to emit the appropriate code for
7143 the case when we have a user-defined operator.
7145 2001-09-17 Miguel de Icaza <miguel@ximian.com>
7147 * rootcontext.cs: Fix bug: tree.Namespaces might be null.
7149 2001-09-16 Ravi Pratap <ravi@ximian.com>

7177 2001-09-14 Miguel de Icaza <miguel@ximian.com>
7179 * class.cs (TypeContainer::FindMembers): Add support for

7190 * modifiers.cs: Do not use `parent', instead use the real type
7191 container to evaluate permission settings.

7206 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
7207 incorrect. IsTopLevel is not used to tell whether an object is
7208 root_types or not (that can be achieved by testing this ==
7209 root_types). But to see if this is a top-level *class* (not
7210 necessarly our "toplevel" container).
7212 2001-09-14 Ravi Pratap <ravi@ximian.com>
7214 * enum.cs (Enum::Define): Modify to call the Lookup method on the
7215 parent instead of a direct call to GetType.
7217 2001-09-14 Ravi Pratap <ravi@ximian.com>
7219 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
7220 Modifiers.TypeAttr. This should just be a call to that method.
7222 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
7223 object so that we can determine if we are top-level or not.
7225 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
7228 * enum.cs (Enum::Define): Ditto.
7230 * modifiers.cs (FieldAttr): Re-write.
7232 * class.cs (TypeContainer::IsTopLevel): Change accessibility to public.
7233 (TypeContainer::HaveStaticConstructor): New property to provide access
7234 to precisely that info.
7236 * modifiers.cs (MethodAttr): Re-write.
7237 (EventAttr): Remove altogether as there seems to be no ostensible use for it.

7242 2001-09-13 Miguel de Icaza <miguel@ximian.com>
7244 * expression.cs (MemberLookup): Fruitless attempt to lookup

7300 (Class::LookupMethodByBuilder): New function that maps
7301 MethodBuilders to its methods. Required to locate the information
7302 on methods because System.Reflection bit us again.
7304 * support.cs: New file, contains an interface ParameterData and
7305 two implementations: ReflectionParameters and InternalParameters
7306 used to access Parameter information. We will need to grow this
7309 * expression.cs (Invocation::GetParameterData): implement a cache
7310 and a wrapper around the ParameterData creation for methods.

7466 (CheckBinaryOperator): Same here.
7468 * rootcontext.cs (LookupType): Add an extra lookup which simply does a lookup
7469 on the name without any prefixes of namespace names etc. This is because we
7470 already might have something already fully qualified like
7471 'System.Console.WriteLine'

7622 will is used during the tree rewriting as we resolve them during

7749 * class.cs (Property): Revamp to use the convention of making fields readonly.

7799 general catch clauses by being a little smart ;-)
7801 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
7802 Hooray, try and catch statements parse fine !

7857 thing - instead, collect the brackets here.
7858 (opt_rank_sepcifiers): Modify accordingly.
7859 (array_type): Modify to actually return the complete type string
7860 instead of ignoring the rank_specifiers.
7861 (expression_list): Implement to collect the expressions
7862 (variable_initializer): Implement. We make it a list of expressions
7863 essentially so that we can handle the array_initializer case neatly too.
7864 (variable_initializer_list): Implement.
7865 (array_initializer): Make it a list of variable_initializers
7866 (opt_array_initializer): Modify accordingly.
7868 * expression.cs (New::NType): Add enumeration to help us
7869 keep track of whether we have an object/delegate creation
7870 or an array creation.
7871 (New:NewType, New::Rank, New::Indices, New::Initializers): New
7872 members to hold data about array creation.
7873 (New:New): Modify to update NewType
7874 (New:New): New Overloaded contructor for the array creation
7877 * cs-parser.jay (array_creation_expression): Implement to call
7878 the overloaded New constructor.
7880 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
7882 * class.cs (TypeContainer::Constructors): Return member
7883 constructors instead of returning null.
7885 2001-08-26 Miguel de Icaza <miguel@ximian.com>
7887 * typemanager.cs (InitCoreTypes): Initialize the various core
7888 types after we have populated the type manager with the user
7889 defined types (this distinction will be important later while
7890 compiling corlib.dll)
7892 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
7893 on Expression Classification. Now all expressions have a method
7894 `Resolve' and a method `Emit'.
7896 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
7897 generation from working. Also add some temporary debugging
7900 2001-08-24 Miguel de Icaza <miguel@ximian.com>
7902 * codegen.cs: Lots of code generation pieces. This is only the
7903 beginning, will continue tomorrow with more touches of polish. We
7904 handle the fundamentals of if, while, do, for, return. Others are
7905 trickier and I need to start working on invocations soon.
7907 * gen-treedump.cs: Bug fix, use s.Increment here instead of
7910 * codegen.cs (EmitContext): New struct, used during code
7911 emission to keep a context. Most of the code generation will be
7914 * cs-parser.jay: Add embedded blocks to the list of statements of
7915 this block. So code generation proceeds in a top down fashion.
7917 2001-08-23 Miguel de Icaza <miguel@ximian.com>
7919 * statement.cs: Add support for multiple child blocks.
7921 2001-08-22 Miguel de Icaza <miguel@ximian.com>
7923 * codegen.cs (EmitCode): New function, will emit the code for a
7924 Block of code given a TypeContainer and its ILGenerator.
7926 * statement.cs (Block): Standard public readonly optimization.
7927 (Block::Block constructors): Link children.
7928 (Block::Child): Child Linker.
7929 (Block::EmitVariables): Emits IL variable declarations.
7931 * class.cs: Drop support for MethodGroups here, delay until
7933 (Method::): Applied the same simplification that I did before, and
7934 move from Properties to public readonly fields.
7935 (Method::ParameterTypes): Returns the parameter types for the
7936 function, and implements a cache that will be useful later when I
7937 do error checking and the semantic analysis on the methods is
7939 (Constructor::GetCallingConvention): Renamed from CallingConvetion
7940 and made a method, optional argument tells whether this is a class
7941 or a structure to apply the `has-this' bit.
7942 (Method::GetCallingConvention): Implement, returns the calling
7944 (Method::Define): Defines the type, a second pass is performed
7945 later to populate the methods.
7947 (Constructor::ParameterTypes): implement a cache similar to the
7948 one on Method::ParameterTypes, useful later when we do semantic
7951 (TypeContainer::EmitMethod): New method. Emits methods.
7953 * expression.cs: Removed MethodGroup class from here.
7955 * parameter.cs (Parameters::GetCallingConvention): new method.
7957 2001-08-21 Miguel de Icaza <miguel@ximian.com>
7959 * class.cs (TypeContainer::Populate): Drop RootContext from the
7962 (Constructor::CallingConvention): Returns the calling convention.
7963 (Constructor::ParameterTypes): Returns the constructor parameter
7966 (TypeContainer::AddConstructor): Keep track of default constructor
7967 and the default static constructor.
7969 (Constructor::) Another class that starts using `public readonly'
7970 instead of properties.
7972 (Constructor::IsDefault): Whether this is a default constructor.
7974 (Field::) use readonly public fields instead of properties also.
7976 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
7977 track of static constructors; If none is used, turn on
7978 BeforeFieldInit in the TypeAttributes.
7980 * cs-parser.jay (opt_argument_list): now the return can be null
7981 for the cases where there are no arguments.
7983 (constructor_declarator): If there is no implicit `base' or
7984 `this', then invoke the default parent constructor.
7986 * modifiers.cs (MethodAttr): New static function maps a set of
7987 modifiers flags into a MethodAttributes enum
7988 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
7989 MethodAttr, TypeAttr to represent the various mappings where the
7991 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
7993 2001-08-19 Miguel de Icaza <miguel@ximian.com>
7995 * parameter.cs (GetParameterInfo): Fix bug where there would be no
7998 * interface.cs (PopulateIndexer): Implemented the code generator
7999 for interface indexers.
8001 2001-08-17 Miguel de Icaza <miguel@ximian.com>
8003 * interface.cs (InterfaceMemberBase): Now we track the new status
8006 (PopulateProperty): Implement property population. Woohoo! Got
8007 Methods and Properties going today.
8009 Removed all the properties for interfaces, and replaced them with
8010 `public readonly' fields.
8012 2001-08-16 Miguel de Icaza <miguel@ximian.com>
8014 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
8015 initialize their hashtables/arraylists only when they are needed
8016 instead of doing this always.
8018 * parameter.cs: Handle refs and out parameters.
8020 * cs-parser.jay: Use an ArrayList to construct the arguments
8021 instead of the ParameterCollection, and then cast that to a
8024 * parameter.cs: Drop the use of ParameterCollection and use
8025 instead arrays of Parameters.
8027 (GetParameterInfo): Use the Type, not the Name when resolving
8030 2001-08-13 Miguel de Icaza <miguel@ximian.com>
8032 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
8033 and instead use public readonly fields.
8035 * class.cs: Put back walking code for type containers.
8037 2001-08-11 Miguel de Icaza <miguel@ximian.com>
8039 * class.cs (MakeConstant): Code to define constants.
8041 * rootcontext.cs (LookupType): New function. Used to locate types
8044 2001-08-08 Miguel de Icaza <miguel@ximian.com>
8046 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
8047 this System.Reflection code is. Kudos to Microsoft
8049 * typemanager.cs: Implement a type cache and avoid loading all
8050 types at boot time. Wrap in LookupType the internals. This made
8051 the compiler so much faster. Wow. I rule!
8053 * driver.cs: Make sure we always load mscorlib first (for
8054 debugging purposes, nothing really important).
8056 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
8057 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
8059 * rootcontext.cs: Lookup types on their namespace; Lookup types
8060 on namespaces that have been imported using the `using' keyword.
8062 * class.cs (TypeContainer::TypeAttr): Virtualize.
8063 (Class::TypeAttr): Return attributes suitable for this bad boy.
8064 (Struct::TypeAttr): ditto.
8065 Handle nested classes.
8066 (TypeContainer::) Remove all the type visiting code, it is now
8067 replaced with the rootcontext.cs code
8069 * rootcontext.cs (GetClassBases): Added support for structs.
8071 2001-08-06 Miguel de Icaza <miguel@ximian.com>
8073 * interface.cs, statement.cs, class.cs, parameter.cs,
8074 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
8075 Drop use of TypeRefs, and use strings instead.
8077 2001-08-04 Miguel de Icaza <miguel@ximian.com>
8081 * class.cs (Struct::Struct): set the SEALED flags after
8082 checking the modifiers.
8083 (TypeContainer::TypeAttr): new property, returns the
8084 TypeAttributes for a class.
8086 * cs-parser.jay (type_list): Oops, list production was creating a
8087 new list of base types.
8089 * rootcontext.cs (StdLib): New property.
8090 (GetInterfaceTypeByName): returns an interface by type name, and
8091 encapsulates error handling here.
8092 (GetInterfaces): simplified.
8093 (ResolveTree): Encapsulated all the tree resolution here.
8094 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
8097 * driver.cs: Add support for --nostdlib, to avoid loading the
8099 (Main): Do not put tree resolution here.
8101 * rootcontext.cs: Beginning of the class resolution.
8103 2001-08-03 Miguel de Icaza <miguel@ximian.com>
8105 * rootcontext.cs: Provide better error reporting.
8107 * cs-parser.jay (interface_base): set our $$ to be interfaces.
8109 * rootcontext.cs (CreateInterface): Handle the case where there
8110 are no parent interfaces.
8112 (CloseTypes): Routine to flush types at the end.
8113 (CreateInterface): Track types.
8114 (GetInterfaces): Returns an array of Types from the list of
8117 * typemanager.c (AddUserType): Mechanism to track user types (puts
8118 the type on the global type hash, and allows us to close it at the
8121 2001-08-02 Miguel de Icaza <miguel@ximian.com>
8123 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
8124 RecordInterface instead.
8126 * cs-parser.jay: Updated to reflect changes above.
8128 * decl.cs (Definition): Keep track of the TypeBuilder type that
8129 represents this type here. Not sure we will use it in the long
8130 run, but wont hurt for now.
8132 * driver.cs: Smaller changes to accomodate the new code.
8134 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
8137 * rootcontext.cs (CreateInterface): New method, used to create
8138 the System.TypeBuilder type for interfaces.
8139 (ResolveInterfaces): new entry point to resolve the interface
8141 (CodeGen): Property, used to keep track of the code generator.
8143 2001-07-26 Miguel de Icaza <miguel@ximian.com>
8145 * cs-parser.jay: Add a second production for delegate_declaration
8148 (enum_body): Put an opt_comma here instead of putting it on
8149 enum_body or enum_member_declarations so we can handle trailing
8150 commas on enumeration members. Gets rid of a shift/reduce.
8152 (type_list): Need a COMMA in the middle.
8154 (indexer_declaration): Tell tokenizer to recognize get/set
8156 * Remove old targets.
8158 * Re-add the parser target.
8160 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8162 * cs-parser.jay: Add precendence rules for a number of operators
8163 ot reduce the number of shift/reduce conflicts in the grammar.
8165 2001-07-17 Miguel de Icaza <miguel@ximian.com>
8167 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
8170 Get rid of old crufty code.
8172 * rootcontext.cs: Use this to keep track of the parsed
8173 representation and the defined types available to the program.
8175 * gen-treedump.cs: adjust for new convention.
8177 * type.cs: Split out the type manager, and the assembly builder
8180 * typemanager.cs: the type manager will live here now.
8182 * cil-codegen.cs: And the code generator here.
8184 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
8186 * makefile: Fixed up for easy making.
8188 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8190 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
8193 (unary_expression): Expand pre_increment_expression and
8194 post_decrement_expression to reduce a shift/reduce.
8196 2001-07-11 Simon Cozens
8198 * cs-tokenizer.cs: Hex numbers should begin with a 0.
8200 Improve allow_keyword_as_indent name.
8202 2001-06-19 Miguel de Icaza <miguel@ximian.com>
8204 * Adjustments for Beta2.
8206 2001-06-13 Miguel de Icaza <miguel@ximian.com>
8208 * decl.cs: Added `Define' abstract method.
8209 (InTransit): new property, used to catch recursive definitions.
8211 * interface.cs: Implement `Define'.
8213 * modifiers.cs: Map Modifiers.constants to
8214 System.Reflection.TypeAttribute flags.
8216 * class.cs: Keep track of types and user-defined types.
8217 (BuilderInit): New method for creating an assembly
8218 (ResolveType): New function to launch the resolution process, only
8219 used by interfaces for now.
8221 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
8222 that are inserted into the name space.
8224 2001-06-08 Miguel de Icaza <miguel@ximian.com>
8226 * ARGH. I have screwed up my tree so many times due to the use of
8227 rsync rather than using CVS. Going to fix this at once.
8229 * driver.cs: Objetify driver. Load assemblies, use assemblies to
8232 2001-06-07 Miguel de Icaza <miguel@ximian.com>
8234 * Experiment successful: Use System.Type rather that our own
8237 2001-05-25 Miguel de Icaza <miguel@ximian.com>
8239 * cs-parser.jay: Removed nsAliases from here.
8241 Use new namespaces, handle `using XXX;'
8243 * namespace.cs: Reimplemented namespace handling, use a recursive
8244 definition of the class. Now we can keep track of using clauses
8245 and catch invalid using clauses.
8247 2001-05-24 Miguel de Icaza <miguel@ximian.com>
8249 * gen-treedump.cs: Adapted for all the renaming.
8251 * expression.cs (Expression): this class now has a Type property
8252 which returns an expression Type.
8254 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
8255 `Type', as this has a different meaning now in the base
8257 2001-05-22 Miguel de Icaza <miguel@ximian.com>
8259 * interface.cs, class.cs: Removed from all the sources the
8260 references to signature computation, as we can not do method
8261 signature computation during the parsing time, as we are not
8262 trying to solve at that point distinguishing:
8266 void a (NS.Blah x) {}
8269 Which depending on the context might be valid or not, as we do not
8270 know if Blah is the same thing as NS.Blah at that point.
8272 * Redid everything so the code uses TypeRefs now instead of
8273 Types. TypeRefs are just temporary type placeholders, that need
8274 to be resolved. They initially have a pointer to a string and the
8275 current scope in which they are used. This is used later by the
8276 compiler to resolve the reference to an actual Type.
8278 * DeclSpace is no longer a CIR.Type, and neither are
8279 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
8280 are all DeclSpaces, but no Types.
8282 * type.cs (TypeRefManager): This implements the TypeRef manager,
8283 which keeps track of all the types that need to be resolved after
8284 the parsing has finished.
8286 2001-05-13 Miguel de Icaza <miguel@ximian.com>
8288 * ARGH. We are going to have to store `foreach' as a class rather
8289 than resolving it, as we need to verify error 1579 after name
8290 resolution. *OR* we could keep a flag that says `This request to
8291 IEnumerator comes from a foreach statement' which we can then use
8292 to generate the error.
8294 2001-05-10 Miguel de Icaza <miguel@ximian.com>
8296 * class.cs (TypeContainer.AddMethod): we now add methods to the
8297 MethodGroup instead of the method hashtable.
8299 * expression.cs: Add MethodGroup abstraction, which gets us one
8300 step closer to the specification in the way we handle method
8303 * cs-parser.jay (primary_expression): qualified_identifier now
8304 tried to match up an identifier to a local variable reference or
8305 to a parameter reference.
8307 current_local_parameters is now a parser global variable that
8308 points to the current parameters for the block, used during name
8311 (property_declaration): Now creates an implicit `value' argument to
8314 2001-05-09 Miguel de Icaza <miguel@ximian.com>
8316 * parameter.cs: Do not use `param' arguments as part of the
8317 signature, per the spec.
8319 2001-05-08 Miguel de Icaza <miguel@ximian.com>
8321 * decl.cs: Base class for classes, structs and interfaces. This
8322 is the "Declaration Space"
8324 * cs-parser.jay: Use CheckDef for checking declaration errors
8325 instead of having one on each function.
8327 * class.cs: Factor out some code for handling error handling in
8328 accordance to the "Declarations" section in the "Basic Concepts"
8329 chapter in the ECMA C# spec.
8331 * interface.cs: Make all interface member classes derive from
8332 InterfaceMemberBase.
8334 2001-05-07 Miguel de Icaza <miguel@ximian.com>
8336 * Many things: all interfaces are parsed and generated in
8337 gen-treedump. Support for member variables, constructors,
8338 destructors, properties, constants is there.
8340 Beginning of the IL backend, but very little done, just there for
8343 2001-04-29 Miguel de Icaza <miguel@ximian.com>
8345 * cs-parser.jay: Fix labeled statement.
8347 * cs-tokenizer.cs (escape): Escape " and ' always.
8348 ref_line, ref_name: keep track of the line/filename as instructed
8349 by #line by the compiler.
8352 2001-04-27 Miguel de Icaza <miguel@ximian.com>
8354 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
8355 to match the values in System.CodeDOM.
8357 Divid renamed to Divide.
8359 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
8361 (Statements.set): remove.
8363 * System.CodeDOM/CodeCatchClause.cs: always have a valid
8366 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
8367 falseStatements always have valid values.
8369 * cs-parser.jay: Use System.CodeDOM now.
