232 2002-07-27 Martin Baulig <martin@gnome.org>
234 * expression.cs (Invocation.EmitArguments): When calling a varargs
235 function with only its fixed arguments, we need to pass an empty
238 2002-07-27 Martin Baulig <martin@gnome.org>
240 Mono 0.13 has been released.
242 2002-07-25 Miguel de Icaza <miguel@ximian.com>
244 * driver.cs: Rename --resource to --linkres, because that is what
245 we do currently, we dont support --resource yet.
247 * cs-tokenizer.cs: Fix test for reporting endif mismatches.
249 2002-07-25 Martin Baulig <martin@gnome.org>
251 * class.cs (MethodData): New public class. This is a `method builder'
252 class for a method or one accessor of a Property/Indexer/Event.

262 accessor/method to MethodData.
263 (Method): Create a new MethodData and call Define() and Emit() on it.
264 (Property, Indexer, Event): Create a new MethodData objects for each
265 accessor and call Define() and Emit() on them.
267 2002-07-25 Martin Baulig <martin@gnome.org>
269 Made MethodCore derive from MemberBase to reuse the code from there.
270 MemberBase now also checks for attributes.
272 * class.cs (MethodCore): Derive from MemberBase, not MemberCore.
273 (MemberBase.GetMethodFlags): Moved here from class Method and marked
275 (MemberBase.DefineAccessor): Renamed to DefineMethod(), added

278 attributes to a method or accessor.
279 (MemberBase.ApplyObsoleteAttribute): New protected virtual method.
280 (MemberBase.ApplyConditionalAttribute): Likewise.
281 (MemberBase.ApplyDllImportAttribute): Likewise.
282 (MemberBase.CheckAbstractAndExternal): Likewise.

287 initialize ParameterTypes and ParameterInfo.
288 (Method.GetReturnType): We can now simply return the MemberType.
289 (Method.GetMethodFlags): Override the MemberBase version and add
290 the conditional flags.
291 (Method.CheckBase): Moved some code from Define() here, call
292 DoDefineParameters() here.

294 here to avoid some larger code duplication.
295 (Property.Emit, Indexer.Emit): Call CheckAbstractAndExternal() to
296 ensure that abstract and external accessors don't declare a body.
298 * attribute.cs (Attribute.GetValidPieces): Make this actually work:
299 `System.Attribute.GetCustomAttributes (attr.Type)' does a recursive
300 lookup in the attribute's parent classes, so we need to abort as soon
301 as we found the first match.
302 (Attribute.Obsolete_GetObsoleteMessage): Return the empty string if
303 the attribute has no arguments.
305 * typemanager.cs (TypeManager.AddMethod): Now takes a MemberBase instead
308 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
310 * cs-parser.jay: reverted previous patch.
312 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
314 * cs-parser.jay: fixed bug #22119.
316 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
318 * attribute.cs: fixed compilation. The error was:
319 "attribute.cs(571,17): error CS0177: The out parameter 'is_error' must
320 be assigned to before control leaves the current method."
321 [FIXME: Filed as bug #28186: MCS must report this error.]
323 2002-07-25 Martin Baulig <martin@gnome.org>
325 * attribute.cs (Attribute.Conditional_GetConditionName): New static
326 method to pull the condition name ouf of a Conditional attribute.
327 (Attribute.Obsolete_GetObsoleteMessage): New static method to pull
328 the obsolete message and error flag out of an Obsolete attribute.
330 * class.cs (Method.GetMethodFlags): New public method to get the
331 TypeManager.MethodFlags for this method.
332 (Method.ApplyConditionalAttribute, Method.ApplyObsoleteAttribute): New
334 (Method.Define): Get and apply the Obsolete and Conditional attributes;
335 if we're overriding a virtual function, set the new private variable
336 `parent_method'; call the new TypeManager.AddMethod().
338 * typemanager.cs (TypeManager.AddMethod): New static method. Stores
339 the MethodBuilder and the Method in a PtrHashtable.
340 (TypeManager.builder_to_method): Added for this purpose.
341 (TypeManager.MethodFlags): Added IsObsoleteError.
342 (TypeManager.GetMethodFlags): Added `Location loc' argument. Lookup
343 Obsolete and Conditional arguments in MethodBuilders. If we discover
344 an Obsolete attribute, emit an appropriate warning 618 / error 619 with
345 the message from the attribute.
347 2002-07-24 Martin Baulig <martin@gnome.org>
349 * cs-tokenizer.cs: Eat up trailing whitespaces and one-line comments in
350 preprocessor directives, ensure that the argument to #define/#undef is
351 exactly one identifier and that it's actually an identifier.
353 Some weeks ago I did a `#define DEBUG 1' myself and wondered why this
356 2002-07-24 Martin Baulig <martin@gnome.org>
358 * statement.cs (Foreach.ForeachHelperMethods): Added `Type element_type',
359 initialize it to TypeManager.object_type in the constructor.
360 (Foreach.GetEnumeratorFilter): Set `hm.element_type' to the return type
361 of the `hm.get_current' method if we're using the collection pattern.
362 (Foreach.EmitCollectionForeach): Use `hm.element_type' as the source type
363 for the explicit conversion to make it work when we're using the collection
364 pattern and the `Current' property has a different return type than `object'.
367 2002-07-24 Martin Baulig <martin@gnome.org>
369 * delegate.cs (Delegate.VerifyMethod): Simply return null if the method
370 does not match, but don't report any errors. This method is called in
371 order for all methods in a MethodGroupExpr until a matching method is
372 found, so we don't want to bail out if the first method doesn't match.
373 (NewDelegate.DoResolve): If none of the methods in the MethodGroupExpr
374 matches, report the 123. Fixes #28070.
376 2002-07-24 Martin Baulig <martin@gnome.org>
378 * expression.cs (ArrayAccess.EmitStoreOpcode): Moved the
379 TypeManager.TypeToCoreType() to the top of the method so the
380 following equality checks will work. Fixes #28107.
382 2002-07-24 Martin Baulig <martin@gnome.org>
384 * cfold.cs (ConstantFold.DoConstantNumericPromotions): "If either
385 operand is of type uint, and the other operand is of type sbyte,
386 short or int, the operands are converted to type long." -
387 Actually do what this comment already told us. Fixes bug #28106,
390 2002-07-24 Martin Baulig <martin@gnome.org>
392 * class.cs (MethodBase): New abstract class. This is now a base
393 class for Property, Indexer and Event to avoid some code duplication
394 in their Define() and DefineMethods() methods.
395 (MethodBase.DoDefine, MethodBase.DefineAccessor): Provide virtual
396 generic methods for Define() and DefineMethods().
397 (FieldBase): Derive from MemberBase, not MemberCore.
398 (Property): Derive from MemberBase, not MemberCore.
399 (Property.DefineMethod): Moved all the code from this method to the
400 new MethodBase.DefineAccessor(), just call it with appropriate
402 (Property.Define): Call the new Property.DoDefine(), this does some
403 sanity checks and we don't need to duplicate the code everywhere.
404 (Event): Derive from MemberBase, not MemberCore.
405 (Event.Define): Use the new MethodBase.DefineAccessor() to define the
406 accessors, this will also make them work with interface events.
407 (Indexer): Derive from MemberBase, not MemberCore.
408 (Indexer.DefineMethod): Removed, call MethodBase.DefineAccessor() insstead.
409 (Indexer.Define): Use the new MethodBase functions.

412 argument to the constructor.
413 (Interface.FindMembers): Added support for interface events.
414 (Interface.PopluateEvent): Implemented.
416 Added test-149.cs for this. This also fixes bugs #26067 and #24256.
418 2002-07-22 Miguel de Icaza <miguel@ximian.com>
420 * class.cs (TypeContainer.AddMethod): Adding methods do not use IsValid,
421 but this is required to check for a method name being the same as
422 the containing class.
426 2002-07-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
428 * interface.cs: initialize variable.
430 2002-07-23 Martin Baulig <martin@gnome.org>
432 Implemented the IndexerName attribute in interfaces.
434 * class.cs (TypeContainer.DefineIndexers): Don't set the indexer
435 name if this is an explicit interface implementation.
436 (Indexer.InterfaceIndexerName): New public variable. If we're
437 implementing an interface indexer, this is the IndexerName in that
438 interface. Otherwise, it's the IndexerName.
439 (Indexer.DefineMethod): If we're implementing interface indexer,
440 set InterfaceIndexerName. Use the new Pending.IsInterfaceIndexer
441 and Pending.ImplementIndexer methods.
442 (Indexer.Define): Also define the PropertyBuilder if we're
443 implementing an interface indexer and this is neither an explicit
444 interface implementation nor do the IndexerName match the one in
447 * pending.cs (TypeAndMethods): Added `MethodInfo [] need_proxy'.
448 If a method is defined here, then we always need to create a proxy
449 for it. This is used when implementing interface indexers.
450 (Pending.IsInterfaceIndexer): New public method.
451 (Pending.ImplementIndexer): New public method.
452 (Pending.InterfaceMethod): Added `MethodInfo need_proxy' argument.
453 This is used when implementing interface indexers to define a proxy
455 (Pending.VerifyPendingMethods): Look in the `need_proxy' array and
456 define a proxy if necessary.
458 * interface.cs (Interface.IndexerName): New public variable.
459 (Interface.PopulateIndexer): Set the IndexerName.
460 (Interface.DefineIndexers): New private method. Populate all the
461 indexers and make sure their IndexerNames match.
463 * typemanager.cs (IndexerPropertyName): Added support for interface
466 2002-07-22 Martin Baulig <martin@gnome.org>
468 * codegen.cs (EmitContext.HasReturnLabel): New public variable.
469 (EmitContext.EmitTopBlock): Always mark the ReturnLabel and emit a
470 ret if HasReturnLabel.
471 (EmitContext.TryCatchLevel, LoopBeginTryCatchLevel): New public
474 * statement.cs (Do.Emit, While.Emit, For.Emit, Foreach.Emit): Save
475 and set the ec.LoopBeginTryCatchLevel.
476 (Try.Emit): Increment the ec.TryCatchLevel while emitting the block.
477 (Continue.Emit): If the ec.LoopBeginTryCatchLevel is smaller than
478 the current ec.TryCatchLevel, the branch goes out of an exception
479 block. In this case, we need to use Leave and not Br.
481 2002-07-22 Martin Baulig <martin@gnome.org>
483 * statement.cs (Try.Emit): Emit an explicit ret after the end of the
484 block unless the block does not always return or it is contained in
485 another try { ... } catch { ... } block. Fixes bug #26506.
486 Added verify-1.cs to the test suite.
488 2002-07-22 Martin Baulig <martin@gnome.org>
490 * statement.cs (Switch.TableSwitchEmit): If we don't have a default,
491 then we do not always return. Fixes bug #24985.
493 2002-07-22 Martin Baulig <martin@gnome.org>
495 * expression.cs (Invocation.OverloadedResolve): Do the BetterFunction()
496 lookup on a per-class level; ie. walk up the class hierarchy until we
497 found at least one applicable method, then choose the best among them.
498 Fixes bug #24463 and test-29.cs.
500 2002-07-22 Martin Baulig <martin@gnome.org>
502 * typemanager.cs (TypeManager.ArrayContainsMethod): Don't check the
503 return types of the methods. The return type is not part of the
504 signature and we must not check it to make the `new' modifier work.
505 Fixes bug #27999, also added test-147.cs.
506 (TypeManager.TypeToCoreType): Added TypeManager.type_type.
508 * expression.cs (Invocation.DoResolve): Call TypeManager.TypeToCoreType()
509 on the method's return type.
511 2002-07-21 Martin Baulig <martin@gnome.org>
513 * assign.cs: Make this work if the rightmost source is a constant and
514 we need to do an implicit type conversion. Also adding a few more tests
515 to test-38.cs which should have caught this.
517 * makefile.gnu: Disable debugging, there's already the mcs-mono2.exe
518 target in the makefile for this. The makefile.gnu is primarily intended
519 for end-users who don't want to debug the compiler.
521 2002-07-21 Martin Baulig <martin@gnome.org>
523 * assign.cs: Improved the Assign class so it can now handle embedded
524 assignments (X = Y = Z = something). As a side-effect this'll now also
525 consume less local variables. test-38.cs now passes with MCS, added
526 a few new test cases to that test.
528 2002-07-20 Martin Baulig <martin@gnome.org>
530 * expression.cs (Binary.EmitBranchable): Emit correct unsigned branch
531 instructions. Fixes bug #27977, also added test-146.cs.
533 2002-07-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
535 * cs-tokenizer.cs: fixed getHex ().
537 2002-07-19 Martin Baulig <martin@gnome.org>
539 * expression.cs (Invocation.EmitParams): Use TypeManager.LookupType(),
540 not Type.GetType() to lookup the array type. This is needed when
541 we're constructing an array of a user-defined type.
542 (ArrayAccess.EmitDynamicInitializers): Only emit the Ldelema for
543 single-dimensional arrays, but also for single-dimensial arrays of
546 2002-07-19 Martin Baulig <martin@gnome.org>
548 * expression.cs (New.DoEmit): Create a new LocalTemporary each time
549 this function is called, it's not allowed to share LocalBuilders
552 2002-07-19 Martin Baulig <martin@gnome.org>
554 * expression.cs (Argument.Resolve): Report an error 118 when trying
555 to pass a type as argument.
557 2002-07-18 Martin Baulig <martin@gnome.org>
559 * ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
560 Conv_R_Un for the signed `long' type.
562 2002-07-15 Miguel de Icaza <miguel@ximian.com>
564 * expression.cs (MemberAccess.DoResolve): Do not reuse the field
565 `expr' for the temporary result, as that will fail if we do
566 multiple resolves on the same expression.
568 2002-07-05 Miguel de Icaza <miguel@ximian.com>
570 * ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
571 ec.TypeContainer for looking up aliases.
573 * class.cs (TypeContainer): Remove LookupAlias from here.
575 * decl.cs (DeclSpace); Move here.
577 2002-07-01 Miguel de Icaza <miguel@ximian.com>
579 * class.cs (FindMembers): Only call filter if the constructor
582 Also handle delegates in `NestedTypes' now. Now we will perform
583 type lookups using the standard resolution process. This also
586 * decl.cs (DeclSpace.ResolveType): New type resolution routine.
587 This uses Expressions (the limited kind that can be parsed by the
588 tree) instead of strings.
590 * expression.cs (ComposedCast.ToString): Implement, used to flag
591 errors since now we have to render expressions.
593 (ArrayCreation): Kill FormElementType. Use ComposedCasts in
596 * ecore.cs (SimpleName.ToString): ditto.
598 * cs-parser.jay: Instead of using strings to assemble types, use
599 Expressions to assemble the type (using SimpleName, ComposedCast,
600 MemberAccess). This should fix the type lookups in declarations,
601 because we were using a different code path for this.
603 * statement.cs (Block.Resolve): Continue processing statements
604 even when there is an error.
606 2002-07-17 Miguel de Icaza <miguel@ximian.com>
608 * class.cs (Event.Define): Also remove the `remove' method from
609 the list of pending items.
611 * expression.cs (ParameterReference): Use ldarg.N (0..3) to
612 generate more compact code.
614 2002-07-17 Martin Baulig <martin@gnome.org>
616 * const.cs (Const.LookupConstantValue): Add support for constant
617 `unchecked' and `checked' expressions.
618 Also adding test case test-140.cs for this.
620 2002-07-17 Martin Baulig <martin@gnome.org>
622 * statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
623 check whether mi.ReturnType implements the IEnumerator interface; the
624 `==' and the IsAssignableFrom() will fail in this situation.
626 2002-07-16 Ravi Pratap <ravi@ximian.com>
628 * ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix
631 2002-07-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
633 * expression.cs: fixed bug #27811.
635 2002-07-14 Miguel de Icaza <miguel@ximian.com>
637 * expression.cs (ParameterReference.AddressOf): Patch from Paolo
638 Molaro: when we are a ref, the value already contains a pointer
639 value, do not take the address of it.
641 2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
642 * removed mb-parser.jay and mb-tokenizer.cs
644 Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
646 * expression.cs: check against the building corlib void type.
648 Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
650 * ecore.cs: fix for valuetype static readonly fields: when
651 initializing them, we need their address, not the address of a copy.
653 Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
655 * typemanager.cs: register also enum_type in corlib.
657 Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
659 * class.cs: allow calling this (but not base) initializers in structs.
661 Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
663 * ecore.cs: make sure we compare against the building base types
666 Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
668 * typemanager.cs: fix TypeToCoreType() to handle void and object
669 (corlib gets no more typerefs after this change).
671 2002-07-12 Miguel de Icaza <miguel@ximian.com>
673 * expression.cs (ArrayCreation.EmitArrayArguments): use
674 Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
676 (ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
677 Conv_Ovf_I_Un for the array arguments. Even if C# allows longs as
678 array indexes, the runtime actually forbids them.
680 * ecore.cs (ExpressionToArrayArgument): Move the conversion code
681 for array arguments here.
683 * expression.cs (EmitLoadOpcode): System.Char is a U2, use that
684 instead of the default for ValueTypes.
686 (New.DoEmit): Use IsValueType instead of
687 IsSubclassOf (value_type)
688 (New.DoResolve): ditto.
689 (Invocation.EmitCall): ditto.
691 * assign.cs (Assign): ditto.
693 * statement.cs (Unsafe): Ok, so I got the semantics wrong.
694 Statements *are* currently doing part of their resolution during
697 Expressions do always resolve during resolve, but statements are
698 only required to propagate resolution to their children.
700 2002-07-11 Miguel de Icaza <miguel@ximian.com>
702 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
704 (LoadAssembly): Do not add the dll if it is already specified
706 (MainDriver): Add the System directory to the link path at the end,
707 after all the other -L arguments.
709 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
710 wrong opcode for loading bytes and bools (ldelem.i1 instead of
711 ldelem.u1) and using the opposite for sbytes.
713 This fixes Digger, and we can finally run it.
715 * driver.cs (UnixParseOption): Move the option parsing here.
716 (CSCParseOption): Implement CSC-like parsing of options.
718 We now support both modes of operation, the old Unix way, and the
719 new CSC-like way. This should help those who wanted to make cross
722 The only thing broken is that /r:, /reference: and /lib: are not
723 implemented, because I want to make those have the same semantics
724 as the CSC compiler has, and kill once and for all the confussion
725 around this. Will be doing this tomorrow.
727 * statement.cs (Unsafe.Resolve): The state is checked during
728 resolve, not emit, so we have to set the flags for IsUnsfe here.
730 2002-07-10 Miguel de Icaza <miguel@ximian.com>
732 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
733 not catch the Error_ObjectRefRequired in SimpleName (as it is
734 possible to have a class/instance variable name that later gets
735 deambiguated), we have to check this here.
737 2002-07-10 Ravi Pratap <ravi@ximian.com>
739 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
740 make static and put into Expression.
742 (Event.Define): Register the private field of the event with the
743 TypeManager so that GetFieldFromEvent can get at it.
745 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
746 keep track of the private field associated with an event which
749 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
752 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
754 2002-07-10 Miguel de Icaza <miguel@ximian.com>
756 * expression.cs (Binary.EmitBranchable): this routine emits the
757 Binary expression in a branchable context. This basically means:
758 we need to branch somewhere, not just get the value on the stack.
760 This works together with Statement.EmitBoolExpression.
762 * statement.cs (Statement.EmitBoolExpression): Use
765 2002-07-09 Miguel de Icaza <miguel@ximian.com>
767 * statement.cs (For): Reduce the number of jumps in loops.
769 (For): Implement loop inversion for the For statement.
771 (Break): We can be breaking out of a Try/Catch controlled section
772 (foreach might have an implicit try/catch clause), so we need to
773 use Leave instead of Br.
775 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
776 now). If the instace expression supports IMemoryLocation, we use
777 the AddressOf method from the IMemoryLocation to extract the
778 address instead of emitting the instance.
780 This showed up with `This', as we were emitting the instance
781 always (Emit) instead of the Address of This. Particularly
782 interesting when This is a value type, as we dont want the Emit
783 effect (which was to load the object).
785 2002-07-08 Miguel de Icaza <miguel@ximian.com>
787 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
789 * statement.cs (Checked): Set the CheckedState during the resolve
790 process too, as the ConvCast operations track the checked state on
791 the resolve process, and not emit.
793 * cs-parser.jay (namespace_member_declaration): Flag that we have
794 found a declaration when we do. This is used to flag error 1529
796 * driver.cs: Report ok when we display the help only.
798 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
800 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
802 2002-07-04 Miguel de Icaza <miguel@ximian.com>
804 * cs-tokenizer.cs (define): We also have to track locally the
805 defines. AllDefines is just used for the Conditional Attribute,
806 but we also need the local defines for the current source code.
808 2002-07-03 Miguel de Icaza <miguel@ximian.com>
810 * statement.cs (While, For, Do): These loops can exit through a
811 Break statement, use this information to tell whether the
812 statement is the last piece of code.
814 (Break): Flag that we break.
816 * codegen.cs (EmitContexts): New `Breaks' state variable.
818 2002-07-03 Martin Baulig <martin@gnome.org>
820 * class.cs (TypeContainer.MethodModifiersValid): Allow override
821 modifiers in method declarations in structs. Otherwise, you won't
822 be able to override things like Object.Equals().
824 2002-07-02 Miguel de Icaza <miguel@ximian.com>
826 * class.cs (Method, Property, Indexer): Do not allow the public
827 modifier to be used in explicit interface implementations.
829 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
830 override modifiers in method declarations in structs
832 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
834 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
835 integer or real overflow, report an error
837 2002-07-02 Martin Baulig <martin@gnome.org>
839 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
840 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
841 to tell the runtime about our newly created System.Object and
842 System.ValueType types.
844 2002-07-02 Miguel de Icaza <miguel@ximian.com>
846 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
847 struct instead of Ldarg/Starg.
849 2002-07-02 Martin Baulig <martin@gnome.org>
851 * expression.cs (Indirection.Indirection): Call
852 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
854 2002-07-02 Martin Baulig <martin@gnome.org>
856 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
857 ValueType, call TypeManager.TypeToCoreType() on it.
858 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
859 the OpCodes.Newarr argument.
861 2002-07-02 Martin Baulig <martin@gnome.org>
863 * expression.cs (Invocation.EmitCall): When compiling corlib,
864 replace all calls to the system's System.Array type to calls to
865 the newly created one.
867 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
868 System.Array methods.
869 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
870 from the system's System.Array type which must be replaced.
872 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
874 * typemanager.cs: load unverifiable_code_ctor so we can build
875 corlib using the correct type. Avoid using GetTypeCode() with
877 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
878 TypeManager.object_type to allow building corlib.
880 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
882 * ecore.cs: handle System.Enum separately in LoadFromPtr().
884 2002-07-01 Martin Baulig <martin@gnome.org>
886 * class.cs: Make the last change actually work, we need to check
887 whether `ifaces != null' to avoid a crash.
889 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
891 * class.cs: when we build structs without fields that implement
892 interfaces, we need to add the interfaces separately, since there is
893 no API to both set the size and add the interfaces at type creation
896 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
898 * expression.cs: the dimension arguments to the array constructors
899 need to be converted if they are a long.
901 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
903 * class.cs: don't emit ldarg.0 if there is no parent constructor
904 (fixes showstopper for corlib).
906 2002-06-29 Martin Baulig <martin@gnome.org>
908 MCS now compiles corlib on GNU/Linux :-)
910 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
911 ie. check for MethodImplOptions.InternalCall.
913 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
914 and TypeManager.attribute_type are null, so we must explicitly check
915 whether parent is not null to find out whether it's an attribute type.
916 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
917 and SetBuilder, not only if the property is neither abstract nor external.
918 This is necessary to set the MethodImplOptions on the accessor methods.
919 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
920 SetBuilder, see Property.Emit().
922 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
923 populate "System.Object", "System.ValueType" and "System.Attribute" since
924 they've already been populated from BootCorlib_PopulateCoreTypes().
926 2002-06-29 Martin Baulig <martin@gnome.org>
928 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
929 is the NullLiteral, we also need to make sure that target_type is not
932 2002-06-29 Martin Baulig <martin@gnome.org>
934 * rootcontext.cs (RootContext.ResolveCore): We must initialize
935 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
936 before calling BootstrapCorlib_ResolveDelegate ().
938 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
940 * statement.cs: fixed build-breaker. All tests passed ok.
942 2002-06-27 Martin Baulig <martin@gnome.org>
944 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
945 for System.Decimal when compiling corlib.
947 2002-06-27 Martin Baulig <martin@gnome.org>
949 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
950 switch blocks which contain nothing but a default clause.
952 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
954 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
956 2002-06-27 Martin Baulig <martin@gnome.org>
958 * ecore.cs (PropertyExpr.PropertyExpr): Call
959 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
961 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
962 is already a TypeBuilder.
964 2002-06-27 Martin Baulig <martin@gnome.org>
966 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
967 `target_type == TypeManager.array_type', not IsAssignableFrom() in
968 the "from an array-type to System.Array" case. This makes it work
969 when compiling corlib.
971 2002-06-27 Martin Baulig <martin@gnome.org>
973 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
974 non-static PropertyExpr, set its InstanceExpression. This makes
975 the `ICollection.Count' property work in System/Array.cs.
977 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
979 * driver.cs: Made error handling more consistent. Errors now
980 tracked by Report class, so many methods which used to return int
981 now return void. Main() now prints success/failure and
982 errors/warnings message.
984 Renamed '--probe' compiler argument to '--expect-error'. Removed
985 the magic number return values (123 and 124). Now, if the
986 expected error occurs, the compiler exits with success (exit value
987 0). If the compilation completes without seeing that particular
988 error, the compiler exits with failure (exit value 1). The
989 makefile in mcs/errors has been changed to handle the new behaviour.
991 * report.cs: Made 'expected error' number a property and renamed
992 it from 'Probe' to 'ExpectedError'.
994 * genericparser.cs: Removed error handling support, since it is
995 now all done by Report class.
997 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
998 class, so parse() no longer returns an int.
1000 * namespace.cs: Use Report.Error instead of GenericParser.error
1002 2002-06-22 Miguel de Icaza <miguel@ximian.com>
1004 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
1005 TypeContainer.AddOperator): At the front of the list put the
1006 explicit implementations, so they get resolved/defined first.
1008 2002-06-21 Miguel de Icaza <miguel@ximian.com>
1010 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
1011 interface type is implemented by this TypeContainer. Used during
1012 explicit interface implementation.
1014 (Property.Define, Indexer.Define, Method.Define): Validate that
1015 the given interface in the explicit implementation is one of the
1016 base classes for the containing type.
1018 Also if we are explicitly implementing an interface, but there is
1019 no match in the pending implementation table, report an error.
1021 (Property.Define): Only define the property if we are
1022 not explicitly implementing a property from an interface. Use the
1023 correct name also for those properties (the same CSC uses,
1024 although that is really not needed).
1026 (Property.Emit): Do not emit attributes for explicitly implemented
1027 properties, as there is no TypeBuilder.
1029 (Indexer.Emit): ditto.
1031 Hiding then means that we do not really *implement* a pending
1032 implementation, which makes code fail.
1034 2002-06-22 Martin Baulig <martin@gnome.org>
1036 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
1037 the return value of Object.GetType(). [FIXME: we need to do this whenever
1038 we get a type back from the reflection library].
1040 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
1042 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
1044 2002-06-20 Miguel de Icaza <miguel@ximian.com>
1046 * attribute.cs: Return null if we can not look up the type.
1048 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
1049 the interface types found.
1051 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
1052 interface types found.
1054 * typemanager.cs (GetInterfaces): Make this routine returns alll
1055 the interfaces and work around the lame differences between
1056 System.Type and System.Reflection.Emit.TypeBuilder in the results
1057 result for GetInterfaces.
1059 (ExpandInterfaces): Given an array of interface types, expand and
1060 eliminate repeated ocurrences of an interface. This expands in
1061 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
1064 2002-06-21 Martin Baulig <martin@gnome.org>
1066 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
1069 2002-06-21 Martin Baulig <martin@gnome.org>
1071 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
1072 and called with one of the core types, return the corresponding typebuilder for
1075 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
1078 2002-06-21 Martin Baulig <martin@gnome.org>
1080 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
1081 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
1082 (Expression.ConvertReferenceExplicit): Likewise.
1084 * expression.cs (ElementAccess.DoResolve): Likewise.
1085 (ElementAccess.DoResolveLValue): Likewise.
1087 2002-06-10 Martin Baulig <martin@gnome.org>
1089 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
1090 add the "value" parameter to the parameter list.
1092 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
1095 2002-06-19 Miguel de Icaza <miguel@ximian.com>
1097 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
1098 the argument to an int, uint, long or ulong, per the spec. Also
1099 catch negative constants in array creation.
1101 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
1103 * class.cs: do not allow the same interface to appear twice in
1104 the definition list.
1106 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
1108 * ecore.cs: don't use ldlen with System.Array.
1110 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
1112 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
1114 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
1116 * modifiers.cs: produce correct field attributes for protected
1117 internal. Easy fix so miguel can work on ther harder stuff:-)
1119 2002-06-18 Miguel de Icaza <miguel@ximian.com>
1121 * pending.cs: New file. Move the code from class.cs here.
1122 Support clearning the pending flag for all methods (when not doing
1123 explicit interface implementation).
1125 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
1127 * rootcontext.cs: added a couple more types needed to bootstrap.
1129 2002-06-17 Miguel de Icaza <miguel@ximian.com>
1131 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
1132 constructor in the type, instead of any constructor in the type
1133 hierarchy. Thanks to Paolo for finding this bug (it showed up as
1134 a bug in the Mono runtime when applying the params attribute).
1136 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1137 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
1139 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
1141 * expression.cs (Unary.ResolveOperator): Use TypeManager
1142 to resolve the type.
1144 2002-06-13 Ravi Pratap <ravi@ximian.com>
1146 * cs-parser.jay (enum_member_declaration): Pass in the attributes
1149 * enum.cs (AddEnumMember): Add support to store the attributes associated
1150 with each member too.
1152 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
1153 field builders too - this takes care of the enum member case.
1155 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
1157 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
1158 address-of operator on both value types and pointers.
1160 2002-06-10 Martin Baulig <martin@gnome.org>
1162 * interface.cs (Interface.PopulateIndexer): Add the indexer's
1163 PropertyBuilder to the `property_builders' list.
1165 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
1166 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
1167 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
1168 find any indexers which are inherited from an interface.
1170 2002-06-09 Martin Baulig <martin@gnome.org>
1172 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
1173 the same type as the constant if necessary. There's also a test-130.cs
1176 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
1178 * typemanager.cs (TypeManager.ChangeType): Previously known as
1179 Enum.ChangeEnumType().
1181 2002-06-09 Martin Baulig <martin@gnome.org>
1183 * expression.cs (Cast.TryReduce): Added support for consts.
1185 2002-06-08 Ravi Pratap <ravi@ximian.com>
1187 * class.cs (Accessor): Hold attributes information so we can pass
1190 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
1191 Modify to pass in attributes attached to the methods.
1193 (add_accessor_declaration, remove_accessor_declaration): Ditto.
1195 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
1196 to handle the Accessor kind :-)
1198 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
1200 2002-06-08 Martin Baulig <martin@gnome.org>
1202 * expression.cs (Unary.TryReduceNegative): Added support for
1205 2002-06-08 Martin Baulig <martin@gnome.org>
1207 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
1208 name can't be found in the `defined_names' - the caller will do a
1209 MemberLookup in this case and thus find methods in System.Enum
1210 such as Enum.IsDefined().
1212 2002-06-08 Martin Baulig <martin@gnome.org>
1214 * enum.cs (Enum.ChangeEnumType): This is a custom version of
1215 Convert.ChangeType() which works with TypeBuilder created types.
1216 (Enum.LookupEnumValue, Enum.Define): Use it here.
1218 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
1219 `TypeBuilder.BaseType != null' check.
1220 (TypeContainer.FindMembers): Only lookup parent members if we
1221 actually have a parent.
1222 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
1223 (ConstructorInitializer.Resolve): Likewise.
1225 * interface.cs (Interface.FindMembers): Added
1226 `TypeBuilder.BaseType != null' check.
1228 * rootcontext.cs (RootContext.ResolveCore): Added
1229 "System.Runtime.CompilerServices.IndexerNameAttribute" to
1230 classes_second_stage.
1232 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
1233 debug_type and trace_type when compiling with --nostdlib.
1235 2002-06-07 Martin Baulig <martin@gnome.org>
1237 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
1238 (AddField): Set it to true when adding a non-static field.
1239 (DefineType): Use `have_nonstatic_fields' to find out whether we
1240 have non-static fields, not `Fields != null'.
1242 2002-06-02 Miguel de Icaza <miguel@ximian.com>
1244 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
1245 dereferencing a null on the static-field code path)
1247 2002-05-30 Martin Baulig <martin@gnome.org>
1249 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
1250 to take command line arguments. Use reflection to call the new
1251 custom `Initialize' function on the symbol writer and pass it the
1252 command line arguments.
1254 * driver.cs (--debug-args): New command line argument to pass command
1255 line arguments to the symbol writer.
1257 2002-05-28 Miguel de Icaza <miguel@ximian.com>
1259 * assign.cs (DoResolve): Forgot to do the implicit conversion to
1260 the target type for indexers and properties. Thanks to Joe for
1263 2002-05-27 Miguel de Icaza <miguel@ximian.com>
1265 * typemanager.cs (MethodFlags): returns the method flags
1266 (Obsolete/ShouldIgnore) that control warning emission and whether
1267 the invocation should be made, or ignored.
1269 * expression.cs (Invocation.Emit): Remove previous hack, we should
1270 not do this on matching a base type, we should do this based on an attribute
1272 Only emit calls to System.Diagnostics.Debug and
1273 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
1274 on the command line.
1276 * rootcontext.cs: Global settings for tracing and debugging.
1278 * cs-tokenizer.cs (define): New utility function to track
1279 defines. Set the global settings for TRACE and DEBUG if found.
1281 2002-05-25 Ravi Pratap <ravi@ximian.com>
1283 * interface.cs (Populate*): Pass in the TypeContainer as well as
1284 the DeclSpace as parameters so that we can create EmitContexts and
1285 then use that to apply attributes etc.
1287 (PopulateMethod, PopulateEvent, PopulateProperty)
1288 (PopulateIndexer): Apply attributes everywhere.
1290 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
1293 (ApplyAttributes): Update accordingly.
1295 We now apply interface attributes for all members too.
1297 2002-05-26 Miguel de Icaza <miguel@ximian.com>
1299 * class.cs (Indexer.Define); Correctly check if we are explicit
1300 implementation (instead of checking the Name for a ".", we
1301 directly look up if the InterfaceType was specified).
1303 Delay the creation of the PropertyBuilder.
1305 Only create the PropertyBuilder if we are not an explicit
1306 interface implementation. This means that explicit interface
1307 implementation members do not participate in regular function
1308 lookups, and hence fixes another major ambiguity problem in
1309 overload resolution (that was the visible effect).
1311 (DefineMethod): Return whether we are doing an interface
1314 * typemanager.cs: Temporary hack until we get attributes in
1315 interfaces (Ravi is working on that) and we get IndexerName
1316 support in interfaces.
1318 * interface.cs: Register the indexers as properties.
1320 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
1321 warning, I have verified that this is a bug in the .NET runtime
1322 (JavaScript suffers of the same problem).
1324 * typemanager.cs (MemberLookup): When looking up members for
1325 interfaces, the parent of an interface is the implicit
1326 System.Object (so we succeed in searches of Object methods in an
1327 interface method invocation. Example: IEnumerable x; x.ToString
1330 2002-05-25 Miguel de Icaza <miguel@ximian.com>
1332 * class.cs (Event): Events should also register if they do
1333 implement the methods that an interface requires.
1335 * typemanager.cs (MemberLookup); use the new GetInterfaces
1338 (GetInterfaces): The code used to lookup interfaces for a type is
1339 used in more than one place, factor it here.
1341 * driver.cs: Track the errors at the bottom of the file, we kept
1344 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
1345 instance if the method we are calling is static!
1347 2002-05-24 Miguel de Icaza <miguel@ximian.com>
1349 * attribute.cs (ApplyAttributes): Make this function filter out
1350 the IndexerName attribute (as that attribute in reality is never
1351 applied) and return the string constant for the IndexerName
1354 * class.cs (TypeContainer.Emit): Validate that all the indexers
1355 have the same IndexerName attribute, and if so, set the
1356 DefaultName attribute on the class.
1358 * typemanager.cs: The return value might contain other stuff (not
1359 only methods). For instance, consider a method with an "Item"
1360 property and an Item method.
1362 * class.cs: If there is a problem with the parameter types,
1365 2002-05-24 Ravi Pratap <ravi@ximian.com>
1367 * ecore.cs (ImplicitConversionExists): Wrapper function which also
1368 looks at user defined conversion after making a call to
1369 StandardConversionExists - we need this for overload resolution.
1371 * expression.cs : Update accordingly the various method calls.
1373 This fixes 2 bugs filed against implicit user defined conversions
1375 2002-05-22 Miguel de Icaza <miguel@ximian.com>
1377 * statement.cs: Track the result of the assignment.
1379 2002-05-21 Miguel de Icaza <miguel@ximian.com>
1381 * expression.cs (MemberAccess): Improved error reporting for
1382 inaccessible members.
1384 2002-05-22 Martin Baulig <martin@gnome.org>
1386 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
1387 itself with debugging support.
1389 2002-05-22 Martin Baulig <martin@gnome.org>
1391 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
1392 Removed, this isn't needed anymore.
1394 2002-05-20 Martin Baulig <martin@gnome.org>
1396 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
1397 be underlying type for an enum.
1399 2002-05-20 Miguel de Icaza <miguel@ximian.com>
1401 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
1402 that splits out the loading of just the core types.
1404 * rootcontext.cs (ResolveCore): Split the struct resolution in
1405 two, so we can load the enumeration underlying types before any
1408 * expression.cs (Is): Bandaid until we fix properly Switch (see
1409 bug #24985 for details).
1411 * typemanager.cs (ImplementsInterface): The hashtable will contain
1412 a null if there are no interfaces implemented.
1414 2002-05-18 Miguel de Icaza <miguel@ximian.com>
1416 * cs-parser.jay (indexer_declarator): It is fine to have array
1419 2002-05-17 Miguel de Icaza <miguel@ximian.com>
1421 * typemanager.cs: (RegisterBuilder): New function used to register
1422 TypeBuilders that implement interfaces. Since
1423 TypeBuilder.GetInterfaces (as usual) does not work with lame
1425 (AddUserType): register interfaces.
1427 (ImplementsInterface): Use the builder_to_ifaces hash if we are
1428 dealing with TypeBuilder. Also, arrays are showing up as
1429 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
1430 methods can not be invoked on them!
1432 * ecore.cs (ExplicitReferenceConversionExists): Made public.
1433 (ImplicitReferenceConversionExists): Split out from
1434 StandardConversionExists.
1436 * expression.cs (As): We were only implementing one of the three
1437 cases for the as operator. We now implement them all.
1438 (Is): Implement the various other cases for Is as well.
1440 * typemanager.cs (CACHE): New define used to control if we want or
1441 not the FindMembers cache. Seems to have a negative impact on
1442 performance currently
1444 (MemberLookup): Nested types have full acess to
1445 enclosing type members
1447 Remove code that coped with instance/static returns for events, we
1448 now catch this in RealFindMembers.
1450 (RealFindMembers): only perform static lookup if the instance
1451 lookup did not return a type or an event.
1453 2002-05-17 Miguel de Icaza <miguel@ximian.com>
1455 * assign.cs (CompoundAssign): We pass more semantic information
1456 now to Compound Assignments than we did before: now we have all
1457 the information at hand, and now we resolve the target *before* we
1458 do the expression expansion, which allows the "CacheValue" method
1459 to have the effect we intended (before, a [x] += 1 would generate
1460 two differen ArrayAccess expressions from the ElementAccess,
1461 during the resolution process).
1463 (CompoundAssign.DoResolve): Resolve target and original_source here.
1465 2002-05-16 Miguel de Icaza <miguel@ximian.com>
1467 * expression.cs (ArrayAccess): dropped debugging information.
1469 * typemanager.cs: Small bug fix: I was always returning i_members,
1470 instead of one of i_members or s_members (depending on which had
1473 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
1474 method is invoked before any code generation takes place, and it
1475 is a mechanism to inform that the expression will be invoked more
1476 than once, and that the method should use temporary values to
1477 avoid having side effects
1479 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
1481 * ecore.cs (Expression.CacheTemporaries): Provide empty default
1484 * expression.cs (Indirection, ArrayAccess): Add support for
1485 CacheTemporaries in these two bad boys.
1487 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
1489 (StoreFromPtr): Handle stobj as well.
1491 * expression.cs (UnaryMutator): Share more code.
1493 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
1494 down: I was not tracking the Filter function as well, which
1495 was affecting the results of the cache.
1497 2002-05-15 Miguel de Icaza <miguel@ximian.com>
1499 * attribute.cs: Remove the hack to handle the CharSet property on
1502 2002-05-14 Miguel de Icaza <miguel@ximian.com>
1504 * attribute.cs (DoResolve): More uglyness, we now only try to
1505 resolve the attribute partially, to extract the CharSet
1506 information (only if we are a StructLayout attribute). Otherwise
1508 (GetExtraTypeInfo): Add some code to conditionally kill in the
1509 future this. I am more and more convinced that the .NET
1510 framework has special code to handle the attribute setting on
1513 * expression.cs (IsParamsMethodApplicable): Revert my previous
1514 foreach change here, it was wrong.
1516 2002-05-13 Miguel de Icaza <miguel@ximian.com>
1518 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
1519 (pp_expr): do not abort on unknown input, just return.
1520 (eval): abort if there are pending chars.
1522 * attribute.cs (Attribute.Resolve): Positional parameters are
1523 optional. Deal with that case.
1525 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
1526 the Ansi/Unicode/Auto information for the type.
1528 (TypeContainer.DefineType): instantiate the EmitContext here, as
1529 we will be using it during the type definition (to resolve
1530 attributes) and during the emit phase.
1532 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
1533 to pull type information out of the attributes
1535 (Attribute.Resolve): track the constructor builder, and allow for
1536 multiple invocations (structs and classes will use this).
1538 * ecore.cs (MemberLookupFinal): new version with all the
1539 parameters customizable.
1541 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
1542 constructors. Return if the result value is null (as the error
1543 would have been flagged already by MemberLookupFinal)
1545 Do not allow instances of abstract classes or interfaces to be
1548 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
1549 We have to compare the assembly property here when dealing with
1550 FamANDAssem and Assembly access modifiers, because we might be
1551 creating an assembly from *modules* (that means that we are not
1552 getting TypeBuilders for types defined in other modules that are
1553 part of this assembly).
1555 (Method.Emit): If the method is marked abstract and has a body,
1558 (TypeContainer.DefineMembers): If both the defined member and the
1559 parent name match are methods, then do not emit any warnings: let
1560 the Method.Define routine take care of flagging warnings. But if
1561 there is a mismatch (method overrides something else, or method is
1562 overriwritten by something, then emit warning).
1564 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
1565 set to null, this means `do not check for the return type on the
1568 (Method.Define): set the return type for the method signature to
1569 null, so that we get methods with the same name and parameters and
1570 different return types. This is used to flag warning 114 (you are
1571 hiding a method, and you probably want to use the new/override
1574 * typemanager.cs (MemberLookup): Implemented proper access
1575 control, closing a long standing set of bug reports. The problem
1576 was that the Framework only has two bits: Public and NonPublic,
1577 and NonPublic includes private and protected methods, but we need
1578 to enforce the FamANDAssem, FamOrAssem and Family.
1580 2002-05-11 Miguel de Icaza <miguel@ximian.com>
1582 * statement.cs (GotoCase): Return true: Ammounts to giving up
1583 knowledge on whether we return or not, and letting the other case
1584 be responsible for it.
1586 2002-05-10 Miguel de Icaza <miguel@ximian.com>
1588 * driver.cs: Do not load directories for each file processed, only
1589 do it if there is a pattern.
1591 * ecore.cs: Report readonly assigns here as well, as we might have
1592 been resolved only by MemberAccess.
1594 (SimpleName.SimpleNameResolve): Also be useful for LValue
1595 resolution. We need this to propagate assign to local readonly variables
1597 * typemanager.cs: Use a ptrhashtable for the criteria, because we
1598 do not want to reuse potential criteria memory.
1600 * class.cs (MyEventBuilder): Set reflected_type;
1602 * ecore.cs (Constantify): Added support for constifying bools.
1604 (RootContext.LookupType): Added a cache for values looked up in
1605 the declaration space.
1607 * typemanager.cs (FindMembers): Now is a front-end to
1608 RealFindMembers, and provides a two-level hashtable-based cache to
1611 15% performance improvement: from 22.5 to 19.2 seconds.
1613 * expression.cs (IsParamsMethodApplicable): use foreach.
1614 (Invocation.DoResolve): ditto.
1615 (New.DoResolve): ditto.
1616 (ArrayCreation.DoResolve): ditto.
1618 * ecore.cs (FindMostEncompassingType): use foreach.
1620 * delegate.cs (NewDelegate.DoResolve): Use foreach
1622 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
1623 (RemoveMethods): use foreach.
1625 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
1626 nested foreach statements instead of for, and also break out of
1627 the inner loop once a match is found.
1629 (Invocation.OverloadResolve): Use foreach, simplify the code.
1631 2002-05-08 Miguel de Icaza <miguel@ximian.com>
1633 * cfold.cs (BinaryFold): During an enumeration evaluation context,
1634 we actually unwrap the expression to allow for extra information
1637 * expression.cs: Use Shr_Un on unsigned operations.
1639 2002-05-08 Ravi Pratap <ravi@ximian.com>
1641 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
1642 applicable operators was not being considered correctly. This closes
1643 the bug Miguel reported.
1645 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
1647 * attribute.cs: check that the type derives from System.Attribute
1648 and report the correct error in that case (moved the duplicate code to
1649 its own method, too).
1651 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
1653 * attribute.cs: lookup attribute type name as the spec says: first the
1654 bare attribute name and then name + "Attribute" (nant compiles with
1655 mcs after this fix).
1657 2002-05-07 Miguel de Icaza <miguel@ximian.com>
1659 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
1660 Because of the way we parse things, we should try to see if a
1661 UIntConstant can fit in an integer.
1663 2002-05-07 Ravi Pratap <ravi@ximian.com>
1665 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
1666 when we are in an explicit context.
1668 (ConvertReferenceExplicit): When converting from Iface type S to Class
1669 T make sure the rules are implemented as an OR.
1671 * parameter.cs (ParameterType): Make it a property for now although the
1672 purpose really isn't anything immediate.
1674 * expression.cs (Is*Applicable): Do better checking on the parameter type
1675 of a ref/out parameter. The ones from the system assemblies are already
1676 marked with the correct type so we don't need to do any correction.
1678 * ecore.cs (StandardConversionExists): Conversion from Interface types to
1679 the object type is standard too so include that.
1681 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1683 * ecore.cs (StandardConversionExists): Augment with missing code:
1684 deal with IntConstant, LongConstants and Enumerations.
1686 * assign.cs: Report the error, instead of failing silently
1688 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
1689 typecontainer that they are declared, because the
1690 typecontainer/namespace will have the list of using clauses that
1693 Assembly Attributes were escaping the normal registration
1696 (EmitCode): Apply attributes within an EmitContext that represents
1697 the container they were declared on.
1699 * cs-parser.jay: Track bases for structs. How did I get this wrong?
1701 2002-05-06 Ravi Pratap <ravi@ximian.com>
1703 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
1704 Revamp completely - make much cleaner as we now operate only
1707 (FindMostSpecificSource, FindMostSpecificTarget): New methods
1708 to implement the logic detailed in the spec more correctly.
1710 (UserDefinedConversion): Update accordingly.
1712 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1714 * statement.cs: Return flow analysis information up.
1716 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
1719 (token): Do not consume an extra character before calling
1722 2002-05-06 Piers Haken <piersh@friskit.com>
1724 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
1726 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1728 * class.cs (Constructor.Emit): Set the IsStatic flag in the
1729 EmitContext during the instance constructor initializer
1730 resolution, to stop access to instance variables.
1732 This is mandated by the spec, last paragraph of the `constructor
1733 initializers' section.
1735 2002-05-05 Miguel de Icaza <miguel@ximian.com>
1737 * cs-parser.jay, class.cs (Accessor): new class used to represent
1738 an accessor (get or set). In the past we used `null' to represent
1739 a missing accessor. But this is ambiguous because there was no
1740 way to tell in abstract indexers/properties if one of them was
1743 Now there is a way of addressing that.
1745 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
1746 instead of FindMembers.
1748 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
1749 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
1751 * attribute.cs: Treat indexers and properties as the same in terms
1752 of applying attributes
1754 * ecore.cs (FindMostEncompassedType): Use statically initialized
1755 EmptyExpressions()s like we do elsewhere to avoid creating useless
1756 objects (and we take this out of the tight loop).
1758 (GetConversionOperators): Move the code to extract the actual
1759 operators to a separate routine to clean things up.
1761 2002-05-04 Miguel de Icaza <miguel@ximian.com>
1763 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
1764 events are always registered FieldBuilders.
1766 * class.cs (FieldBase): New class shared by Fields
1768 * delegate.cs: If we are a toplevel delegate, use our full name.
1769 If we are a nested delegate, then only use our tail name.
1771 2002-05-02 Ravi Pratap <ravi@ximian.com>
1773 * expression.cs (IsApplicable): Ensure that we add the "&" to
1774 ref/out types before comparing it with the type of the argument.
1776 (IsParamsMethodApplicable): Ditto.
1778 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
1781 * delegate.cs : Handle the case when we have more than one applicable
1782 method. Flag an error only when we finish checking all.
1784 2002-05-02 Miguel de Icaza <miguel@ximian.com>
1786 * expression.cs: Add support for boolean static initializers.
1788 2002-05-01 Miguel de Icaza <miguel@ximian.com>
1790 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
1792 * parameter.cs (ComputeParameterTypes,
1793 ComputeAndDefineParameterTypes): Better error handling: now we
1794 clear the `types' cache if we fail during any of the type lookups.
1795 We also return the status code correctly to our caller
1797 * delegate.cs: If we fail to define a delegate, abort the extra
1800 * expression.cs (Binary.ResolveOperator): for
1801 operator==(object,object) and operator !=(object, object) we also
1802 have to verify that there is an implicit conversion from one to
1805 (ArrayAccess.DoResolve): Array Access can operate on
1808 2002-04-30 Miguel de Icaza <miguel@ximian.com>
1810 * assign.cs (CompoundAssign): A new class used as a "flag" that
1811 the assignment actually is happening as part of a compound
1812 assignment operator.
1814 During compound assignment, a few new rules exist to enable things
1821 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
1822 to the type of x) if y is implicitly convertible to the type of x,
1823 and the operator is a builtin operator and the return type of the
1824 operator is explicitly convertible to the type of x.
1826 * rootcontext.cs: Reset warning level to 2. 4 catches various
1827 "interesting" features in mcs, we must clean this up at some
1828 point, but currently am trying to kill other bugs ;-)
1830 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
1831 in container classes as well.
1833 * expression.cs (Binary.ResolveOperator): Handle string case
1834 before anything else (as operator overloading does emit an error
1835 before doing anything else).
1837 This code could go away when we move to a table driven model, but
1838 i could not come up with a good plan last night.
1840 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
1842 * typemanager.cs (CSharpName): reimplementation using regex.
1843 * class.cs: added null check for fields in Emit
1844 * rootcontext.cs: set warninglevel to 4
1846 2002-04-29 Miguel de Icaza <miguel@ximian.com>
1848 * typemanager.cs (CSharpName): reimplemented with Lupus
1851 2002-04-28 Miguel de Icaza <miguel@ximian.com>
1853 * statement.cs (If): correclty implement Resolve, because we were
1854 not catching sem errors in there. The same process is needed
1856 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
1859 (Statement.Warning_DeadCodeFound): Factorize code.
1860 (While): Report dead code here too.
1862 (Statement): Added Resolve virtual method to allow
1863 for resolution split from the emit code.
1865 2002-04-26 Miguel de Icaza <miguel@ximian.com>
1867 * statement.cs (EmitBoolExpression): No longer try to resolve the
1869 (MakeBoolean): New utility function that resolve, implicitly
1870 converts to boolean and tags the expression.
1873 (If, Do): Implement dead code elimination.
1874 (While): Implement loop inversion
1876 (Do, While, For, If): Resolve the expression prior to calling our
1879 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
1882 - added method Report28 (warning: program has more than one entry point)
1883 - added method IsEntryPoint, implements paragraph 10.1 of the spec
1884 - modified method Method.Define, the part at the end of the method
1886 * rootcontext.cs: added static public Location EntryPointLocation;
1888 * ../errors/cs0028.cs : Add test case for the above warning.
1891 - modified method CSharpName to allow arrays of primitive type to
1892 be printed nicely (e.g. instead of System.Int32[][] it now prints
1894 - added method CSharpSignature: returns the signature of a method
1895 in string format to be used in reporting errors, warnings, etc.
1897 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
1900 2002-04-26 Ravi Pratap <ravi@ximian.com>
1902 * delegate.cs (Define): Fix extremely silly bug where I was
1903 setting the type of the 'object' parameter of the BeginInvoke
1904 method to System.IAsyncResult instead of System.Object ;-)
1906 2002-04-26 Miguel de Icaza <miguel@ximian.com>
1908 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
1911 (Constructor.Emit): return if we fail to initialize the
1912 constructor. Another door closed!
1914 * expression.cs (New.DoResolve): Improve error message (from -6 to
1915 1501). Use DeclaredOnly lookup to find the exact constructor.
1917 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
1918 loop. This is useful.
1920 * cs-parser.jay: Adjust the default parameters so that destructors
1921 have the proper signature.
1923 2002-04-26 Martin Baulig <martin@gnome.org>
1925 * driver.cs (LoadAssembly): If `assembly' contains any characters
1926 which are only valid in path names and not in assembly names
1927 (currently slash, backslash and point), use Assembly.LoadFrom ()
1928 instead of Assembly.Load () on the `assembly' (before iteration
1929 over the link_paths).
1931 2002-04-26 Martin Baulig <martin@gnome.org>
1933 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
1935 2002-04-25 Miguel de Icaza <miguel@ximian.com>
1937 * class.cs (Property): use the new typemanager.MemberLookup
1939 (TypeContainer.MemberLookup): Implement using the
1940 TypeManager.MemberLookup now.
1942 * typemanager.cs: Make MemberLookup a function of the TypeManager,
1943 and return MemberInfos, so that these can be used without an
1944 EmitContext (what we had before).
1946 2002-04-24 Miguel de Icaza <miguel@ximian.com>
1948 * expression.cs: Fix the case where the argument to params if the
1949 type of the params. I omitted handling this before. Fixed
1951 2002-04-22 Miguel de Icaza <miguel@ximian.com>
1953 * driver.cs: Call BootCorlib_PopulateCoreType
1955 * class.cs (Property.CheckBase): Check for properties only, not
1958 * interface.cs: Temporary hack: try/catch around the
1959 CustomAttributeBuilder, because I am getting an exception that I
1962 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
1963 types whose definitions are required to be there (attributes are
1964 defined before standard types).
1966 Compute definitions as we boot the various types, as they are used
1967 immediately (value_type class will need object_type, but if we do
1968 not initialize object_type, we will pass a null, which will let
1969 the runtime pick the System.Object from the existing corlib, which
1970 is not what we want).
1972 2002-04-22 Patrik Torstensson <totte@labs2.com>
1974 * cs-tokenizer.cs: fixed a number of trim() issues.
1976 2002-04-22 Ravi Pratap <ravi@ximian.com>
1978 * expression.cs (Argument.Type): Ensure that we return the correct
1979 type when we have out or ref parameters [in which case we
1982 2002-04-22 Miguel de Icaza <miguel@ximian.com>
1984 * class.cs (Property, Indexer): Allow extern modifier in there.
1986 * typemanager.cs (InitBaseTypes): Initializes object_type and
1987 value_type, since those will be used early on during the bootstrap
1988 process to compile corlib.
1990 (InitCoreTypes): Move code from here to InitBaseTypes.
1992 2002-04-21 Miguel de Icaza <miguel@ximian.com>
1994 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
1995 single-dimension arrays as using the ldlen opcode.
1997 Daniel Lewis discovered this optimization.
1999 * typemanager.cs: Add signature for System.Array::get_Length
2001 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2003 * statement.cs: report the error when the foreach does not apply to an
2004 array nor a collection.
2006 2002-04-19 Miguel de Icaza <miguel@ximian.com>
2008 * expression.cs: Add implicit conversions to the operator ~.
2010 * constant.cs (DecimalConstant.Emit): Emit decimal value.
2012 * typemanager.cs: Locate the decimal constructor.
2014 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2016 * attribute.cs: use the new property of TypeOf.
2017 * expression.cs: added 'get' property around typearg.
2019 These changes fix a build breaker reported by NickD. Is this the
2020 correct way to fix? If not, please, revert my changes and make it
2023 2002-04-17 Miguel de Icaza <miguel@ximian.com>
2025 * attribute.cs: Add support for typeof in attribute invocations.
2026 I am not sure that this is right though.
2028 2002-04-14 Duncan Mak <duncan@ximian.com>
2030 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
2031 Binary.Operator.Division case.
2033 2002-04-13 Ravi Pratap <ravi@ximian.com>
2035 * class.cs (DefineType): Ensure that we do a proper check on
2036 attribute types and also register it with the TypeManager.
2038 (TypeContainer.Targets): The default for attribute types is
2039 AttributeTargets.All.
2041 * attribute.cs (ApplyAttributes): Registering the attribute type
2042 is done elsewhere, not when we discover we have a Usage attribute.
2044 2002-04-12 Ravi Pratap <ravi@ximian.com>
2046 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
2047 and get rid of is_delegate parameter.
2049 * everywhere : update.
2051 2002-04-12 Ravi Pratap <ravi@ximian.com>
2053 * cs-parser.jay (compilation_unit): Revamp completely to use
2054 some new ideas that I got from Rhys' grammar to solve the problems
2055 with assembly level attributes.
2057 (outer_declaration): New grammar production.
2059 (attribute_sections): Add.
2061 (opt_attributes): Base on attribute_sections
2063 (namespace_declaration): Allow opt_attributes to tackle the case
2064 when we have assembly level attributes - we are clever in this
2067 * attribute.cs (ApplyAttributes): Do not worry about assembly
2068 attributes in the non-global context.
2070 * rootcontext.cs (AddGlobalAttributes): Go back to using this
2071 instead of SetGlobalAttributes.
2073 * class.cs, rootcontext.cs : Ensure we define and generate
2074 attribute types before anything else.
2076 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
2077 and flag the new error -20 for the case when the attribute type
2078 does not have valid targets specified. csc does not catch this.
2080 * ../errors/errors.txt : update for error # -20
2082 2002-04-11 Ravi Pratap <ravi@ximian.com>
2084 * support.cs (InternalParameters.ParameterModifier): Do some null
2085 checking and return sane values.
2087 * class.cs (Method.Define): If we are a PInvoke method, ensure
2088 that we are static and extern. Report error # 601
2090 * ../errors/cs0601.cs : Add test case for the above error.
2092 2002-04-07 Ravi Pratap <ravi@ximian.com>
2094 * rootcontext.cs (attribute_types): We need to keep type of
2095 all attribute types separately and emit code for them first.
2097 (RegisterAttribute) : Implement.
2099 * class.cs (DefineType): Check if the current Type is a custom
2100 attribute type and register it accordingly.
2102 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
2103 adding the first attribute twice and rename to
2105 (SetGlobalAttributes): this.
2107 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
2110 * attribute.cs (ApplyAttributes): Take an additional argument telling us
2111 if we are processing global arguments. Hmm, I am unsure of this.
2113 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2115 * expression.cs: added static array of strings to avoid calling
2116 Enum.ToString () for Operator in Binary. Significant recover of
2119 2002-04-10 Miguel de Icaza <miguel@ximian.com>
2121 * class.cs (FindMembers): Allow the Builders of the various
2122 members to be null. If they are skip them. This only happens
2123 during the PInvoke declaration.
2125 2002-04-09 Miguel de Icaza <miguel@ximian.com>
2127 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
2128 failure, so we do not keep going afterwards.
2130 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
2131 wanted to pass `false' as the `is_delegate' argument. If this is
2132 the case, why not use delegate_type == null to mean `is_delegate =
2133 false' and anything else as is_delegate = true.
2135 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
2137 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
2138 code for the section, not the beginning of the tests.
2140 2002-04-08 Miguel de Icaza <miguel@ximian.com>
2142 * cfold.cs: Handle operator + (Enum x, Underlying x)
2144 * expression.cs (Binary): same. Warn about errors where we have
2145 Enum/Enum in operator + as well.
2147 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
2150 - added support for switch(bool)
2151 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
2152 - add TableSwitchEmit() to handle table-based switch statements
2154 2002-04-05 Ravi Pratap <ravi@ximian.com>
2156 * expression.cs (Invocation.OverloadResolve): Factor out code which
2157 does parameter compatibility checking with arguments so that we can
2158 re-use the code even from Delegate.VerifyApplicability
2160 (VerifyArgumentsCompat): Move above code here.
2162 * delegate.cs (VerifyApplicability): Get rid of duplicate code
2163 and instead make a call to the above method.
2165 2002-03-31 Ravi Pratap <ravi@ximian.com>
2167 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
2168 We use it to keep track of classes which are attribute types.
2170 2002-04-02 Miguel de Icaza <miguel@ximian.com>
2172 * delegate.cs (Delegate.Define): Correctly define the types in the
2173 presence of fixed and array parameters.
2175 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
2178 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
2179 include NonPublic after the first iteration.
2181 * class.cs (Indexer.CheckBase): Only check if both parents are
2184 * cs-parser.jay (accessor_body): If empty, set to null.
2186 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
2187 same code path here to resolve constants names that we did have in
2188 MemberAccess.DoResolve. There is too much code duplicated here.
2190 2002-04-01 Miguel de Icaza <miguel@ximian.com>
2192 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
2194 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
2197 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
2198 tokens, numbers and strings.
2200 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
2203 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
2204 asyncronous parameters and the regular parameters.
2206 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
2207 specify the target directory.
2209 * expression.cs: (This.DoResolve): Simplify
2210 (As.Emit): Optimize, do not generate IsInst if the expression is
2211 always of the given type.
2213 (Is.DoResolve): Bug fix, we were reporting both always/never for
2216 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
2217 creating too many unnecessary arrays.
2219 2002-03-31 Miguel de Icaza <miguel@ximian.com>
2221 * class.cs (EmitFieldInitializer): Use Assign expression to assign
2222 fields instead of rolling our own initializer. Takes care of all
2223 implicit conversions, and drops unnecessary static checks/argument.
2225 2002-03-31 Dick Porter <dick@ximian.com>
2227 * driver.cs: use the GetDirectories() return values properly, and
2228 use "/" as path separator.
2230 2002-03-30 Miguel de Icaza <miguel@ximian.com>
2232 * expression.cs (Unary): Optimize - - expr into expr.
2233 (Binary): Optimize a + (-b) into a -b.
2235 * codegen.cs (CodeGen): Made all methods static.
2237 2002-03-29 Miguel de Icaza <miguel@ximian.com>
2241 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
2242 TypeBuilder property.
2244 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
2247 * tree.cs: Removed the various RecordXXXX, and replaced with a
2248 single RecordDecl. Removed all the accessor methods, and just
2249 left a single access point Type
2251 * enum.cs: Rename DefineEnum to DefineType.
2253 * decl.cs: New abstract method `DefineType' used to unify the
2254 Defines for Enumerations, Interfaces, TypeContainers and
2257 (FindType): Moved LookupInterfaceOrClass here. Moved the
2258 LookupBaseClasses method that used to live in class.cs and
2259 interface.cs here, and renamed to FindType.
2261 * delegate.cs: Implement DefineType. Take advantage of the
2262 refactored pattern for locating the parent builder without taking
2263 the parent_builder argument (which we know does not work if we are
2264 nested, and triggering a toplevel definition).
2266 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2268 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
2269 accessibility of a member has changed during override and report
2272 * class.cs (Method.Define, Property.Define): Only complain on
2273 overrides if the method is private, any other accessibility is
2274 fine (and since we just checked the permission is the same, we are
2277 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
2278 and elif are processed always. The other pre-processing
2279 directives are only processed if we are "taking" the path
2281 2002-03-29 Martin Baulig <martin@gnome.org>
2283 * class.cs (Method.Emit): Only emit symbolic debugging info if the
2284 current location is not Null.
2286 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
2287 a separate method so we can profile it.
2289 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
2290 `span.Seconds' are just seconds, but no minutes or hours.
2291 (MainDriver): Profile the CodeGen.SaveSymbols calls.
2293 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2295 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
2296 Remove the gratuitous set of Final:
2298 // If an interface implementation, then we can set Final.
2299 if (((flags & MethodAttributes.Abstract) == 0) &&
2300 implementing.DeclaringType.IsInterface)
2301 flags |= MethodAttributes.Final;
2303 I do not know what I was smoking when I used that.
2306 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
2307 step into fixing the name resolution issues for delegates and
2308 unifying the toplevel name resolution.
2310 2002-03-28 Martin Baulig <martin@gnome.org>
2312 * class.cs (Method.Emit): If we have a symbol writer, call its
2313 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
2314 tell it about the current method.
2316 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
2317 writer that we're going to emit the first byte of IL code for a new
2318 statement (a new source line).
2319 (EmitContext.EmitTopBlock): If we have a symbol writer, call
2320 EmitContext.Mark() before emitting any code.
2322 * location.cs (SymbolDocument): Return null when we're Null.
2324 * statement.cs (Statement): Moved the `Location loc' variable here.
2325 (Statement.EmitBoolExpression): If we have a symbol writer, call
2326 ec.Mark() before emitting any code to tell it that we're at the
2327 beginning of a new statement.
2328 (StatementExpression): Added `Location' argument to the constructor.
2329 (Block): Added public readonly variable `StartLocation' and public
2330 variable `EndLocation'. The latter is to be set using SetEndLocation().
2331 (Block): Added constructor which takes a start and end location.
2332 (Block.SetEndLocation): New method. This sets the end location.
2333 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
2334 local variables we create.
2335 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
2336 each statement and do also mark the begin and end of the block.
2338 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
2339 tell it the current lexer.Location, use Location.Null for the end of the
2341 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
2342 current block, set its end location using SetEndLocation().
2343 (statement_expression): StatementExpression constructor now takes the
2344 lexer.Location as additional argument.
2345 (for_statement, declare_local_variables): Likewise.
2346 (declare_local_variables): When creating a new implicit block, use the
2347 new Block constructor and pass it the lexer.Location.
2349 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2351 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
2352 members also on the parent interfaces recursively.
2354 2002-03-27 Miguel de Icaza <miguel@ximian.com>
2356 * report.cs: Use new formats, since Gonzalo finished the missing
2359 * expression.cs (Binary.ResolveOperator): added missing operator|
2360 operator& and operator^ for bool/bool.
2362 * cs-parser.jay: CheckDef now takes a Location argument that is
2363 used to report errors more precisly (instead of reporting the end
2364 of a definition, we try to track something which is a lot closer
2365 to the source of the problem).
2367 * cs-tokenizer.cs: Track global token use, so we can properly flag
2368 the use of #define/#undef after the first token has been seen.
2370 Also, rename the reportXXXX to Error_DescriptiveName
2372 * decl.cs (DeclSpace.IsTopLevel): Move property here from
2373 TypeContainer, so that Enum and Interface can use this too.
2375 * class.cs (TypeContainer.LookupInterfaceOrClass,
2376 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
2377 `builder' argument. Typically this was used to pass the parent
2378 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
2381 The problem is that a nested class could trigger the definition of
2382 a toplevel class, and the builder would be obviously wrong in that
2385 So we drop this argument, and we compute dynamically the
2386 TypeBuilder/ModuleBuilder (the correct information was available
2387 to us anyways from DeclSpace.Parent)
2389 * interface.cs (Interface.DefineInterface): Drop builder
2390 parameter cleanup like class.cs
2392 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
2395 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
2398 (Try.Emit): Propagate the returns value from the statement.
2400 (Return.Emit): Even if we are leavning
2402 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
2404 * modifiers.cs: Fix the computation of MethodAttributes flags.
2406 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
2408 * driver.cs: allow compilation of files that start with '/'.
2409 Add a default case when checking the argument of --target.
2411 2002-03-25 Miguel de Icaza <miguel@ximian.com>
2413 * interface.cs: Implement the same search algorithm for types in
2416 * delegate.cs: Do not allow multiple definition.
2418 * Recovered ChangeLog that got accidentally amputated
2420 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
2422 * rootcontext.cs: Load manually enum to allow core classes to
2423 contain enumerations.
2425 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
2426 Update to new static methods in TypeManager.
2428 * typemanager.cs (GetMethod, GetConstructor): Use our
2429 implementation of FindMembers to find the members, since during
2430 corlib compilation, the types are TypeBuilders and GetMethod and
2431 GetConstructor do not work.
2433 Make all methods in TypeManager static.
2435 (InitCodeHelpers): Split the functionality from
2436 the InitCodeTypes function.
2438 * driver.cs: Call InitCodeHelpers after we have populated the
2441 * cs-parser.jay (delegate_declaration): we did not used to compute
2442 the delegate name correctly for void delegates.
2444 2002-03-24 Miguel de Icaza <miguel@ximian.com>
2446 * rootcontext.cs (RootContext): Init the interface_resolve_order
2447 and type_container_resolve_order always.
2449 (ResolveCore, BootstrapCorlib_ResolveClass,
2450 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
2451 compiler when compiling with --nostdlib
2453 * class.cs (TypeContainer.DefineType): Check that our parent is
2454 not null. This test is most important when we are bootstraping
2457 * codegen.cs: Split out the symbol writing code.
2459 2002-03-25 Martin Baulig <martin@gnome.org>
2461 * driver.cs (-g): Made -g an alias for --debug.
2463 2002-03-24 Martin Baulig <martin@gnome.org>
2465 * codegen.cs (SymbolWriter): New public variable. Returns the
2466 current symbol writer.
2467 (CodeGen): Added `bool want_debugging_support' argument to the
2468 constructor. If true, tell the ModuleBuild that we want debugging
2469 support and ask it for the ISymbolWriter.
2470 (Save): If we have a symbol writer, call it's Close() method after
2471 saving the assembly.
2473 * driver.c (--debug): New command line argument to create a
2474 debugger information file.
2476 * location.cs (SymbolDocument): New public property. Returns an
2477 ISymbolDocumentWriter object for the current source file or null
2478 if we don't have a symbol writer.
2480 2002-03-21 Miguel de Icaza <miguel@ximian.com>
2482 * driver.cs (LoadAssembly): Correctly return when all the paths
2483 have been tried and not before.
2485 * statement.cs (Switch.Emit): return the actual coverage for this
2486 statement (returns/not-returns)
2488 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
2489 switch of the statement if we are the last switch section. That
2490 kills two problems: try/catch problems (we used to emit an empty
2491 nop at the end) and switch statements where all branches would
2494 2002-03-19 Miguel de Icaza <miguel@ximian.com>
2496 * driver.cs: Add default assemblies (the equivalent to the
2497 Microsoft CSC.RSP file)
2499 * cs-tokenizer.cs: When updating `cols and setting it to zero,
2500 also update tokens_seen and set it to false.
2502 * driver.cs: Implement --recurse for Mike.
2504 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
2505 correctly splitting out the paths.
2507 2002-03-18 Miguel de Icaza <miguel@ximian.com>
2509 * interface.cs (Interface.PopulateProperty): Instead of using
2510 `parent' as the declaration space for the set parameters, use
2513 * support.cs (InternalParameters): InternalParameters constructor
2514 takes a DeclSpace instead of a TypeContainer.
2516 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
2517 types are being initialized, load the address of it before calling
2520 (New): Provide a mechanism to disable the generation of local
2521 value type temporaries when the caller will be providing us with
2522 an address to store it.
2524 (ArrayCreation.EmitDynamicInitializers): Use it.
2526 2002-03-17 Miguel de Icaza <miguel@ximian.com>
2528 * expression.cs (Invocation.EmitArguments): Only probe for array
2529 property if there is more than one argument. Sorry about that.
2531 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
2534 * class.cs (Method.LabelParameters): Fix incorrect code path that
2535 prevented the `ParamArrayAttribute' from being applied to the
2538 2002-03-16 Miguel de Icaza <miguel@ximian.com>
2540 * support.cs (ReflectionParameters): Correctly compute whether the
2541 last argument is a params array. Fixes the problem with
2544 * typemanager.cs: Make the assemblies array always be non-null
2545 (empty, but non-null)
2547 * tree.cs (RecordDecl): New function that abstracts the recording
2548 of names. This reports error 101, and provides a pointer to the
2549 previous declaration. Fixes a crash in the compiler.
2551 * cs-parser.jay (constructor_declaration): Update to new grammar,
2552 and provide a constructor_body that can be empty.
2554 2002-03-15 Miguel de Icaza <miguel@ximian.com>
2556 * driver.cs: Add support for --resources.
2558 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
2559 Make all types for the various array helper methods be integer.
2561 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
2562 CheckState to ConvCast.
2564 (ConvCast): Now it takes a `checked' state argument, to avoid
2565 depending on the emit context for the conversion, and just using
2566 the resolve time setting.
2568 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
2569 instead of Invocation.EmitArguments. We do not emit the original
2570 arguments, instead we emit those which have been converted to
2571 unsigned int expressions.
2573 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
2575 * codegen.cs: ditto.
2577 * expression.cs (LocalVariableReference): Drop the use of the
2578 Store function that depended on the variable index.
2580 * statement.cs (VariableInfo): Drop the `Idx' property from this
2581 class, as this is not taking into account the indexes for
2582 temporaries tat we generate during the execution, getting the
2585 * class.cs: First emit class initializers, then call the parent
2588 * expression.cs (Binary): Fix opcode emision.
2589 (UnaryMutator.EmitCode): Support checked code generation
2591 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
2592 matches for events for both the Static and Instance scans,
2593 pointing to the same element. Fix that.
2595 2002-03-14 Miguel de Icaza <miguel@ximian.com>
2597 * rootcontext.cs (ResolveTree): Always set the
2598 interface_resolve_order, because nested interfaces will be calling
2601 * class.cs (GetInterfaceOrClass): Track the same resolution
2602 process used by TypeManager.LookupType. This fixes the nested
2603 type lookups in class declarations (separate path from
2606 (TypeContainer.DefineType): Also define nested interfaces.
2607 (TypeContainer.RegisterOrder): New public function used to
2608 register the order in which child interfaces need to be closed.
2610 Nested interfaces need to be closed after their parents have been
2613 * interface.cs (InterfaceAttr): Put all the logic for computing
2614 the interface attribute here.
2616 (DefineInterface): Register our interface order with the
2617 RootContext or with the TypeContainer depending on the case.
2619 2002-03-12 Miguel de Icaza <miguel@ximian.com>
2621 * cs-parser.jay: rework foreach statement to work with the new
2622 changes to the policy on SimpleNames.
2624 * report.cs: support Stacktrace on warnings as well.
2626 * makefile: drop --unsafe and /unsafe from the compile.
2628 2002-03-13 Ravi Pratap <ravi@ximian.com>
2630 * ecore.cs (StandardConversionExists): Modify to take an Expression
2631 as the first parameter. Ensure we do null -> reference type conversion
2634 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
2635 temporary Expression objects.
2637 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
2639 * interface.cs: workaround bug in method overloading resolution
2640 (there is already a bugzilla bug for it).
2642 2002-03-12 Miguel de Icaza <miguel@ximian.com>
2644 We could also solve this problem by having a separate path for
2645 performing type lookups, instead of DoResolve, we could have a
2646 ResolveType entry point, and only participating pieces of the
2647 production (simplename, deref, array) would implement this.
2649 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
2650 signal SimpleName to only resolve type names and not attempt to
2651 resolve anything else.
2653 * expression.cs (Cast): Set the flag.
2655 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
2657 * class.cs: Only report 108 if there is no `new' modifier.
2659 * cs-parser.jay: rework foreach statement to work with the new
2660 changes to the policy on SimpleNames.
2662 * report.cs: support Stacktrace on warnings as well.
2664 * makefile: drop --unsafe and /unsafe from the compile.
2666 2002-03-11 Miguel de Icaza <miguel@ximian.com>
2668 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
2669 lookups here, instead of doing that at parse time. This means
2670 that our grammar will not introduce `LocalVariableReferences' as
2671 expressions at this point. That solves the problem of code like
2679 This is only half the fix. The full fix requires parameters to
2680 also be handled in this way.
2682 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
2683 makes the use more obvious of the DeclSpace. The
2684 ec.TypeContainer.TypeBuilder is now only used to pull the
2687 My theory is that I can get rid of the TypeBuilder completely from
2688 the EmitContext, and have typecasts where it is used (from
2689 DeclSpace to where it matters).
2691 The only pending problem is that the code that implements Aliases
2692 is on TypeContainer, and probably should go in DeclSpace.
2694 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
2695 lookups here, instead of doing that at parse time. This means
2696 that our grammar will not introduce `LocalVariableReferences' as
2697 expressions at this point. That solves the problem of code like
2705 This is only half the fix. The full fix requires parameters to
2706 also be handled in this way.
2708 * class.cs (Property.DefineMethod): When implementing an interface
2709 method, set newslot, when implementing an abstract method, do not
2710 set the flag (before we tried never setting it, or always setting
2711 it, which is the difference).
2712 (Indexer.DefineMethod): same.
2713 (Method.DefineMethod): same.
2715 * ecore.cs: Only set the status used flag if we get back a Field.
2717 * attribute.cs: Temporary hack, so Paolo can keep working.
2719 2002-03-08 Ravi Pratap <ravi@ximian.com>
2721 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
2722 the unmanaged type in the case we have a MarshalAs attribute.
2724 (Resolve): Handle the case when we are parsing the special MarshalAs
2725 attribute [we need to store the unmanaged type to use later]
2727 * typemanager.cs (marshal_as_attr_type): Built in type for the
2728 MarshalAs Attribute.
2730 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
2731 on parameters and accordingly set the marshalling info.
2733 2002-03-09 Miguel de Icaza <miguel@ximian.com>
2735 * class.cs: Optimizing slightly by removing redundant code after
2736 we switched to the `NoTypes' return value.
2737 (Property.DefineMethod): use NoTypes here too.
2739 This fixes the bug I introduced in my last batch of changes.
2741 2002-03-05 Ravi Pratap <ravi@ximian.com>
2743 * tree.cs (RecordEnum): Add. We now keep track of enums too.
2745 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
2746 Enums since those are types too.
2748 * cs-parser.jay (enum_declaration): Record enums as we parse them.
2750 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
2751 thanks to a call during the lookup process.
2753 2002-03-07 Miguel de Icaza <miguel@ximian.com>
2755 * statement.cs (Foreach): Lots of work to accomodate a particular
2756 kind of foreach statement that I had not kept in mind. It is
2757 possible to have foreachs on classes that provide a GetEnumerator
2758 method that return objects that implement the "pattern" for using
2759 a foreach, there is no need to support GetEnumerator
2762 This is needed to compile nant.
2764 * decl.cs: Only report 114 if the member is not `Finalize' and if
2765 the warning level is at least 2.
2767 * class.cs: Moved the compare function from Method to
2770 (MethodSignature.InheritableMemberSignatureCompare): Add new
2771 filter function that is used to extract inheritable methods from a
2774 (Method.Define): Use the new `inheritable_method_signature_filter'
2777 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
2780 2002-03-06 Miguel de Icaza <miguel@ximian.com>
2782 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
2784 * cs-parser.jay: Add opt_semicolon to the interface declaration.
2786 * expression.cs: Pass location information to
2787 ConvertImplicitStandard.
2789 * class.cs: Added debugging code to track return values from
2792 2002-03-05 Miguel de Icaza <miguel@ximian.com>
2794 * expression.cs (Is.DoResolve): If either side of the `is' is an
2795 interface, do not flag the warning.
2797 * ecore.cs (ImplicitReferenceConversion): We need a separate test
2800 * report.cs: Allow for --fatal to be used with --probe.
2802 * typemanager.cs (NoTypes): Move the definition for the empty Type
2805 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
2807 (TypeContainer.DefineProxy): New function used to proxy to parent
2808 implementations when implementing interfaces.
2809 (TypeContainer.ParentImplements): used to lookup if our parent
2810 implements a public function that is required by an interface.
2811 (TypeContainer.VerifyPendingMethods): Hook this up.
2813 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
2814 `modules' and `assemblies' arraylists into arrays. We only grow
2815 these are the very early start up of the program, so this improves
2816 the speedof LookupType (nicely measured).
2818 * expression.cs (MakeByteBlob): Replaced unsafe code with
2819 BitConverter, as suggested by Paolo.
2821 * cfold.cs (ConstantFold.Binary): Special case: perform constant
2822 folding of string concatenation, but if either side is a string,
2823 and the other is not, then return null, and let the runtime use
2824 the concatenation on the string plus the object (using
2827 2002-03-04 Miguel de Icaza <miguel@ximian.com>
2829 Constant Folding has been implemented now.
2831 * expression.cs (Unary.Reduce): Do not throw an exception, catch
2832 the error instead on types that are not supported in one's
2835 * constant.cs (Constant and all children): New set of functions to
2836 perform implict and explicit conversions.
2838 * ecore.cs (EnumConstant): Implement the new functions to perform
2839 conversion by proxying to the child expression.
2841 * codegen.cs: (ConstantCheckState): Constant evaluation has its
2842 own separate setting that can not be turned off from the command
2843 line using --unchecked or --checked and is only controlled using
2844 the checked/unchecked statements and expressions. This setting is
2845 used by the constant folder to flag errors.
2847 * expression.cs (CheckedExpr, UncheckedExpr): Set the
2848 ConstantCheckState as well.
2850 During Resolve, they also have to flag the state, because the
2851 constant folder runs completely in the Resolve phase.
2853 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
2856 2002-03-01 Miguel de Icaza <miguel@ximian.com>
2858 * cfold.cs: New file, this file contains the constant folder.
2860 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
2861 argument to track whether we are using the resulting address to
2862 load or store a value and provide better error messages.
2864 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
2865 new AddressOf arguments.
2867 * statement.cs (Foreach.EmitCollectionForeach): Update
2869 * expression.cs (Argument.Emit): Call AddressOf with proper
2870 arguments to track usage.
2872 (New.DoEmit): Call AddressOf with new arguments.
2874 (Unary.Emit): Adjust AddressOf call.
2876 2002-03-01 Ravi Pratap <ravi@ximian.com>
2878 * cs-parser.jay (member_access): Change the case for pre-defined types
2879 to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
2882 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
2885 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
2886 essentially like methods and apply attributes like MethodImplOptions to them too.
2888 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
2891 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
2892 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
2895 * Update code everywhere accordingly.
2897 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
2899 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
2901 2002-02-28 Ravi Pratap <ravi@ximian.com>
2903 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
2904 try performing lookups against those instead of jumping straight into using
2905 the 'using' clauses.
2907 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
2909 (LookupType): Perform lookups in implicit parents too.
2911 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
2912 sequence as RootContext.LookupType.
2914 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
2915 the various cases of namespace lookups into this method.
2917 2002-03-01 Miguel de Icaza <miguel@ximian.com>
2919 * cs-parser.jay: Add support for [Attribute ()] (empty arguments
2920 in positional arguments)
2922 * class.cs (Operator): Update the AllowedModifiers to contain
2925 * cs-parser.jay: Update operator declaration to allow for the
2926 operator body to be empty.
2928 * cs-tokenizer.cs: Added '\u' unicode support in strings and hex
2931 2002-02-27 Miguel de Icaza <miguel@ximian.com>
2933 * class.cs (Method.Emit): Label parameters.
2935 * driver.cs: Return 1 or 0 as the program exit code.
2937 2002-02-26 Miguel de Icaza <miguel@ximian.com>
2939 * expression.cs: Special case the `null' object when trying to
2940 auto-compute the type, as anything can be explicitly converted to
2943 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
2944 spotting this Paolo.
2946 (Expression.ImplicitNumericConversion): Perform comparissions of
2947 the type using the underlying type in the case of an enumeration
2948 rather than using the enumeration type for the compare.
2950 Cope with the underlying == type case, which is not possible to
2953 (Expression.ConvertNumericExplicit): Perform comparissions of
2954 the type using the underlying type in the case of an enumeration
2955 rather than using the enumeration type for the compare.
2957 * driver.cs: If the user does not supply an extension, assume .exe
2959 * cs-parser.jay (if_statement): Rewrote so that we can track the
2960 location for the if statement.
2962 * expression.cs (Binary.ConstantFold): Only concat strings when
2963 the operation is "+", not everything ;-)
2965 * statement.cs (Statement.EmitBoolExpression): Take a location
2967 (If, While, Do): Track location.
2969 * expression.cs (Binary.ResolveOperator): In the object + string
2970 case, I was missing a call to ConvertImplicit
2972 2002-02-25 Ravi Pratap <ravi@ximian.com>
2974 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
2975 Location arguments. Ensure we use RootContext.LookupType to do our work
2976 and not try to do a direct Type.GetType and ModuleBuilder.GetType
2978 * interface.cs (PopulateMethod): Handle the type of the parameter being
2981 * expression.cs (Invocation.BetterFunction): Handle the case when we
2982 have a params method with no fixed arguments and a call is made with no
2985 2002-02-25 Miguel de Icaza <miguel@ximian.com>

2988 the verbatim-string-literal
2990 * support.cs (InternalParameters.ParameterModifier): handle null
2992 (InternalParameters.ParameterType): ditto.
2994 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
2995 duplicating the name of the variable parameter.
2996 (GetParameterByName): Fix bug where we were not looking up array
2997 paramters if they were the only present (thanks Paolo!).
2998 (GetParameterInfo): We only have an empty set of types if both
2999 fixed and array are set to null.
3000 (GetParameterInfo-idx): Handle FixedParameter == null
3002 * cs-parser.jay: Handle the case where there is no catch
3003 statements (missing null test).
3005 2002-02-22 Miguel de Icaza <miguel@ximian.com>
3007 * driver.cs (MainDriver): Be conservative on our command line
3010 Catch DirectoryNotFoundException when calling GetFiles.
3012 (SplitPathAndPattern): Used to split the input specification into
3013 a path and a pattern that we can feed to Directory.GetFiles.
3015 2002-02-21 Miguel de Icaza <miguel@ximian.com>
3017 * statement.cs (Fixed): Implement the last case of the Fixed
3018 statement (string handling).
3020 * expression.cs (StringPtr): New class used to return a char * to
3021 a string; Used by the Fixed statement.
3023 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
3025 * expression.cs (Binary.ResolveOperator): Remove redundant
3026 MemberLookup pn parent type.
3027 Optimize union call, we do not need a union if the types are the same.
3028 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
3031 Specialize the use of MemberLookup everywhere, instead of using
3032 the default settings.
3034 (StackAlloc): Implement stackalloc keyword.
3036 * cs-parser.jay: Add rule to parse stackalloc.
3038 * driver.cs: Handle /h, /help, /?
3040 * expression.cs (MakeByteBlob): Removed the hacks we had in place
3041 before we supported unsafe code.
3043 * makefile: add --unsafe to the self compilation of mcs.
3045 2002-02-20 Miguel de Icaza <miguel@ximian.com>
3047 * expression.cs (PointerArithmetic): New class that is used to
3048 perform pointer arithmetic.
3049 (Binary.Resolve): Handle pointer arithmetic
3050 Handle pointer comparission.
3051 (ArrayPtr): Utility expression class that is used to take the
3052 address of an array.
3054 (ElementAccess): Implement array access for pointers
3056 * statement.cs (Fixed): Implement fixed statement for arrays, we
3057 are missing one more case before we are done.
3059 * expression.cs (Indirection): Implement EmitAssign and set the
3060 ExprClass to Variable. This allows pointer dereferences to be
3061 treated as variables, and to have values assigned to them.
3063 * ecore.cs (Expression.StoreFromPtr): New utility function to
3064 store values dereferencing.
3066 2002-02-20 Ravi Pratap <ravi@ximian.com>
3068 * expression.cs (Binary.ResolveOperator): Ensure that we are
3069 not trying to operate on a void type - this fixes the reported
3072 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
3073 the parent implementation is sealed.
3075 * ../errors/cs0239.cs : Add.
3077 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
3079 * typemanager.cs (unverifiable_code_type): Corresponds to
3080 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
3081 which have unsafe code in them.
3083 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
3086 2002-02-19 Miguel de Icaza <miguel@ximian.com>
3088 * cs-tokenizer.cs: Add support for @"litreal strings"
3090 Make tokenizer accept pre-processor directives
3091 on any column (remove the old C-like limitation).
3093 * rootcontext.cs (EmitCode): Emit any global attributes.
3094 (AddGlobalAttributes): Used to keep track of assembly attributes.
3096 * attribute.cs (ApplyAttributes): Support AssemblyAttributes.

3100 2002-02-17 Miguel de Icaza <miguel@ximian.com>
3102 * expression.cs (Indirection): New helper class. Unary will
3103 create Indirection classes to be able to implement the
3104 IMemoryLocation interface on it.
3106 2002-02-16 Miguel de Icaza <miguel@ximian.com>
3108 * cs-parser.jay (fixed_statement): reference the right statement.
3110 * statement.cs (Fixed.Emit): Finish implementing the fixed
3111 statement for the &x case.
3113 2002-02-14 Miguel de Icaza <miguel@ximian.com>
3115 * class.cs (Property.Define, Method.Define): Remove newslot when
3118 * modifiers.cs: My use of NewSlot when `Abstract' was set was
3119 wrong. NewSlot should only be used if the `new' keyword is present.
3121 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
3122 locating our system dir. Sorry about this.
3124 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3126 * driver.cs (GetSystemDir): Compute correctly the location of our
3127 system assemblies. I was using the compiler directory instead of
3128 the library directory.
3130 2002-02-13 Ravi Pratap <ravi@ximian.com>
3132 * expression.cs (BetterFunction): Put back in what Miguel commented out
3133 since it is the correct fix. The problem is elsewhere ;-)
3135 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
3136 parameters of the parms method are themselves compatible or not !
3138 (StandardConversionExists): Fix very dangerous bug where we were forgetting
3139 to check that a class implements an interface before saying that an implicit
3140 conversion was allowed. Use ImplementsInterface to do the checking.
3142 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3144 * class.cs (Method.Define): Track whether we are an explicit
3145 implementation or not. And only call DefineMethodOverride if we
3146 are an explicit implementation.
3148 (Property.DefineMethod): Ditto.
3150 2002-02-11 Ravi Pratap <ravi@ximian.com>
3152 * expression.cs (BetterFunction): Catch hideous bug which was
3153 preventing us from detecting ambiguous calls due to implicit casts i.e
3156 2002-01-29 Miguel de Icaza <miguel@ximian.com>
3158 * support.cs (Pair): Remove un-needed method. I figured why I was
3159 getting the error in cs-parser.jay, the variable in a foreach loop
3160 is readonly, and the compiler does not really treat this as a variable.
3162 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
3163 instead of EQUALS in grammar.
3165 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
3167 * expression.cs (Unary.DoResolve): Check whether the argument is
3170 2002-01-28 Miguel de Icaza <miguel@ximian.com>
3172 * support.cs: Api for Pair to set a value. Despite the fact that
3173 the variables are public the MS C# compiler refuses to compile
3174 code that accesses the field if the variable is part of a foreach
3177 * statement.cs (Fixed): Begin implementation of the fixed
3180 (Block.AddVariable): Return the VariableInfo on success and null
3181 on failure instead of true/false.
3183 * cs-parser.jay (foreach): Catch errors on variables already
3184 defined (we were ignoring this value before) and properly unwind
3187 (fixed_statement): grammar for the fixed statement.
3189 2002-01-25 Miguel de Icaza <miguel@ximian.com>
3191 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
3192 pointer types to be incretemented.
3194 (SizeOf): Implement.
3196 * cs-parser.jay (pointer_member_access): Implement
3197 expr->IDENTIFIER production.
3199 * expression.cs (IndexerAccess.DoResolve, ArrayAccess.DoResolve,
3200 MemberAccess.DoResolve, Invocation.DoResolve): Check for pointers
3203 (Unary): Implement indirection.
3205 * ecore.cs (Expression.UnsafeError): Reports error 214 (pointer
3206 use in non-unsafe context).
3208 (SimpleName.DoResolve): Check for pointers in field access on safe
3211 (Expression.LoadFromPtr): Factor the load-indirect code in this
3212 function. This was duplicated in UnboxCast and ParameterReference
3214 2002-01-24 Miguel de Icaza <miguel@ximian.com>
3216 * expression.cs (ComposedCast): report an error if a pointer cast
3217 is used in a safe region.
3219 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
3220 pointer type casts in unsafe context.
3222 * codegen.cs (EmitContext): Set up IsUnsafe.
3224 * cs-parser.jay (non_expression_type): Add productions for pointer
3227 * expression.cs (Invocation.EmitCall): Remove chunk of buggy
3228 code. We should not use force into static mode if the method is
3229 not virtual. Fixes bug in MIS
3231 * statement.cs (Do.Emit, While.Emit, For.Emit,
3232 Statement.EmitBoolExpression): Add support to Do and While to
3233 propagate infinite loop as `I do return' semantics.
3235 Improve the For case to also test for boolean constants.
3237 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
3238 to the list of attributes we can add.
3240 Remove `EmitContext' argument.
3242 * class.cs (Method.Define): Apply parameter attributes.
3243 (Constructor.Define): Apply parameter attributes.
3244 (MethodCore.LabelParameters): Move here the core of labeling
3247 * support.cs (ReflectionParameters.ParameterModifier,
3248 InternalParameters.ParameterModifier): Use IsByRef on the type and
3249 only return the OUT bit for these parameters instead of in/out/ref
3252 This is because I miss-understood things. The ParameterInfo.IsIn
3253 and IsOut represent whether the parameter has the [In] and [Out]
3256 2002-01-22 Miguel de Icaza <miguel@ximian.com>
3258 * ecore.cs (FieldExpr.Emit): Release temporaries.
3260 * assign.cs (LocalTemporary.Release): new function.
3262 * codegen.cs (EmitContext.GetTemporaryStorage,
3263 EmitContext.FreeTemporaryStorage): Rework the way we deal with
3264 temporary storage. Now we can "put back" localbuilders when we
3267 2002-01-21 Miguel de Icaza <miguel@ximian.com>
3269 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
3270 need to make a copy of the variable to generate verifiable code.
3272 2002-01-19 Miguel de Icaza <miguel@ximian.com>
3274 * driver.cs: Compute dynamically the system directory.
3276 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
3277 Slower, but more generally useful. Used by the abstract
3278 registering implementation.
3280 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
3281 the rules for the special rule on Type/instances. First check if
3282 we have the same name, and if so, try that special static path
3283 rather than the instance path.
3285 2002-01-18 Miguel de Icaza <miguel@ximian.com>
3287 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
3290 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
3291 Enum, ValueType, Delegate or Array for non-corlib compiles.
3293 * cs-tokenizer.cs: Catch long identifiers (645)
3295 * typemanager.cs (IndexerPropetyName): Ravi never tested this
3298 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
3299 fix, we were returning too early, so we were not registering
3300 pending methods from abstract classes.
3302 Do not register pending methods if the class is abstract.
3304 * expression.cs (Conditional.DoResolve): Report circular implicit
3305 conversions when we neecd to compute it for conditional
3308 (Is.DoResolve): If the expression is always of the provided type,
3309 flag warning 183. If the expression can not ever be of the
3310 provided type flag warning 184.
3312 * class.cs: Catch 169 as well.
3314 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
3317 2002-01-18 Nick Drochak <ndrochak@gol.com>
3319 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.
3321 2002-01-17 Miguel de Icaza <miguel@ximian.com>
3323 * interface.cs: (PopulateMethod): Check for pointers being defined
3324 only if the unsafe context is active.
3325 (PopulateProperty): ditto.
3326 (PopulateIndexer): ditto.
3328 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
3329 specified. If pointers are present, make sure that they are
3330 present in an unsafe context.
3331 (Constructor, Constructor.Define): ditto.
3332 (Field, Field.Define): ditto.
3333 (Property, Property.Define): ditto.
3334 (Event, Event.Define): ditto.
3336 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
3337 hashtable if there are classes or structs defined.
3339 * expression.cs (LocalVariableReference.DoResolve): Simplify this
3340 code, as the constant resolution moved.
3342 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
3343 the metadata, so we can flag error 133.
3345 * decl.cs (MemberCore.UnsafeOK): New function to test that a
3346 pointer is being declared in an unsafe context.
3348 2002-01-16 Miguel de Icaza <miguel@ximian.com>
3350 * modifiers.cs (Modifiers.Check): Require a Location argument.
3351 Report error 227 for Unsafe use.
3353 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
3355 * statement.cs (For.Emit): If the test is null, then report that
3356 we do `return', as we wont reach anything afterwards.
3358 (Switch.SwitchGoverningType): Track the expression that matched
3361 * driver.cs: Allow negative numbers as an error code to flag.
3363 * cs-parser.jay: Handle 1551.
3365 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
3367 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3369 * cs-parser.jay: Report 1518 (type declaration can only contain
3370 class, struct, interface, enum or delegate)
3372 (switch_label): Report 1523 (keywords `case' or `default' must
3375 (opt_switch_sections): Report 1522 (empty switch)
3377 * driver.cs: Report 1515 (response file specified multiple times)
3378 Report 1516 (Source file specified multiple times).
3380 * expression.cs (Argument.Resolve): Signal 1510
3382 (BaseAccess.Resolve, BaseIndexer.Resolve): Signal 1511 (base
3383 access not allowed in static code)
3385 2002-01-11 Ravi Pratap <ravi@ximian.com>
3387 * typemanager.cs (IsPointerType): Utility method which we are going
3390 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
3391 the object type, so we take care of that.
3393 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
3395 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
3396 added to non-params parameters :-)
3398 * typemanager.cs (CSharpName): Include 'void' type too.
3400 (void_ptr_type): Include in the set of core types.
3402 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
3405 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
3408 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
3409 completely forgotten about it.
3411 2002-01-10 Ravi Pratap <ravi@ximian.com>
3413 * cs-parser.jay (pointer_type): Add. This begins our implementation
3414 of parsing rules for unsafe code.
3416 (unsafe_statement): Implement.
3418 (embedded_statement): Modify to include the above.
3420 * statement.cs (Unsafe): Implement new class for unsafe blocks.
3422 * codegen.cs (EmitContext.InUnsafe): Add. This determines
3423 if the current context is an unsafe one.
3425 * cs-parser.jay (local_variable_pointer_type): Since local variable types
3426 are handled differently, we need separate rules for them.
3428 (local_variable_declaration): Update to use local_variable_pointer_type
3429 to allow variable declarations of unmanaged pointer types.
3431 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
3434 * ../errors/cs0214.cs : Add.
3436 2002-01-16 Nick Drochak <ndrochak@gol.com>
3438 * makefile: remove 'response' file when cleaning.
3440 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3442 * cs-parser.jay: Report 1524.
3444 2002-01-14 Miguel de Icaza <miguel@ximian.com>
3446 * typemanager.cs (RegisterMethod): drop checking if we have
3447 registered this from here
3449 2002-01-12 Miguel de Icaza <miguel@ximian.com>
3451 * class.cs (Method.EmitDestructor): Implement calling our base
3454 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
3457 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
3458 this routine and will wrap the call in a try/catch block. Deal
3461 2002-01-11 Miguel de Icaza <miguel@ximian.com>
3463 * ecore.cs (Expression.MemberLookup): instead of taking a
3464 parameter `same_type' that was used to tell whether we could
3465 access private members we compute our containing type from the
3468 (FieldExpr): Added partial support for volatile fields. This does
3469 not work for volatile fields exposed from assemblies, as I can not
3470 figure out how to extract the modreq from it.
3472 Updated all the source files to use this.
3474 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
3475 because it is referenced by MemberLookup very often.
3477 2002-01-09 Ravi Pratap <ravi@ximian.com>
3479 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
3480 TypeBuilder.GetCustomAttributes to retrieve what we need.
3482 Get rid of redundant default_member_attr_type as this is the same as
3483 default_member_type which already exists.
3485 * interface.cs, attribute.cs : Update accordingly.
3487 2002-01-08 Miguel de Icaza <miguel@ximian.com>
3489 * typemanager.cs: Enable IndexerPropertyName again. It does not
3490 work for TYpeBuilders though. Ravi, can you please fix this?
3492 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
3494 * expression.cs (Argument.Emit): Handle the case of ref objects
3495 being passed to ref functions;
3497 (ParameterReference.EmitLoad): Loads the content of the pointer
3498 without dereferencing.
3500 2002-01-07 Miguel de Icaza <miguel@ximian.com>
3502 * cs-tokenizer.cs: Implemented the pre-processing expressions.
3504 2002-01-08 Ravi Pratap <ravi@ximian.com>
3506 * class.cs (Indexer.DefineMethod): Incorporate the interface
3507 type in the name of the method if we are doing explicit interface
3510 * expression.cs (ConversionExists): Remove as it is completely obsolete.
3512 (BetterConversion): Fix extremely trivial bug where we were referring to
3513 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
3516 * ../errors/bug16.cs : Add although we have fixed it.
3518 2002-01-07 Miguel de Icaza <miguel@ximian.com>
3520 * expression.cs (BaseIndexer): Begin implementation.
3522 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
3524 * cs-parser.jay (indexer_declarator): Use qualified_identifier
3525 production directly to remove a shift/reduce, and implement
3526 explicit interface implementation.
3528 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
3529 after a floating point suffix.
3531 * expression.cs (DoNumericPromotions): Improved the conversion for
3532 uint/uint. If we have a constant, we avoid doing a typecast to a
3535 * class.cs (Indexer): Implement explicit interface implementation
3538 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
3540 * class.cs: make the default instance constructor public and hidebysig.
3542 2001-01-03 Ravi Pratap <ravi@ximian.com>
3544 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
3545 so we can call it from elsewhere.
3547 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
3548 we emit it internally if the class has a defined indexer; otherwise the user
3549 emits it by decorating the class definition with the DefaultMemberAttribute.
3551 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
3552 attribute is not used on a type which defines an indexer.
3554 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
3555 character when we skip whitespace.
3557 * ../errors/cs0646.cs : Add.
3559 2002-01-03 Miguel de Icaza <miguel@ximian.com>
3561 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
3564 * makefile: Add practical target `mcs3.exe' which builds the third
3565 generation compiler.
3567 * expression.cs (New): Fix structures constructor calling.
3569 * class.cs (Property, Method, Indexer): Emit Final flag on the
3570 method if we are an interface implementation and we are not
3573 * ecore.cs (PropertyExpr): New public field `IsBase', tells
3574 whether this property is referencing a `base' method.
3576 * expression.cs (Invocation.EmitCall): take an extra argument:
3577 is_base, this is used to determine whether the `call' or
3578 `callvirt' opcode should be used.
3581 * delegate.cs: update EmitCall.
3583 * class.cs (Method.Define): Set NewSlot for the cases where we are
3584 not implementing an interface method.
3586 (Property.Define): ditto.
3588 2002-01-02 Miguel de Icaza <miguel@ximian.com>
3590 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
3591 'r'. Allows mcs to parse itself fully.
3593 2002-01-02 Ravi Pratap <ravi@ximian.com>
3595 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
3596 of the number of initializers that require the InitializeArray method.
3598 (CheckIndices): Store the Expression in all cases - not the plain value. Also
3599 update the above field where necessary.
3601 (MakeByteBlob): Update accordingly.
3603 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
3606 (EmitDynamicInitializers): Update in accordance with the new optimization.
3608 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
3609 same OpCode applies.
3611 * cs-parser.jay : Fix some glaring errors I introduced.
3613 2002-01-01 Ravi Pratap <ravi@ximian.com>
3615 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
3616 so that we can check for name clashes there too.
3618 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
3619 for interface indexers.
3621 * interfaces.cs (Define): Emit the default member attribute.
3623 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
3624 variable was being referred to while setting the value ;-)
3626 2002-01-01 Miguel de Icaza <miguel@ximian.com>
3628 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
3629 byte-by-byte information when we know the data is zero.
3631 Make the block always a multiple of 4, because
3632 DefineInitializedData has a bug.
3634 * assign.cs: Fix, we should assign from the temporary, not from
3637 * expression.cs (MakeByteBlob): Fix my incorrect code.
3639 2001-12-31 Miguel de Icaza <miguel@ximian.com>
3641 * typemanager.cs (EnumToUnderlying): This function is used to get
3642 the underlying type from an enumeration, because it does not
3645 * constant.cs: Use the I4_S form for values between -128 and 127.
3647 * statement.cs (Block.LookupLabel): Looks up a label.
3648 (Block): Drop support for labeled blocks.
3650 (LabeledStatement): New kind of statement that represents a label
3653 (Goto): Finally implement this bad boy.
3655 * cs-parser.jay: Update to reflect new mechanism to implement
3658 2001-12-30 Miguel de Icaza <miguel@ximian.com>
3660 * codegen.cs (EmitContext.This): a codegen property that keeps the
3661 a single instance of this instead of creating many different this
3664 * delegate.cs (Delegate.DoResolve): Update to use the property;
3666 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
3668 * expression.cs (BaseAccess.DoResolve): Ditto.
3670 2001-12-29 Ravi Pratap <ravi@ximian.com>
3672 * typemanager.cs (methodimpl_attr_type): Add to hold the type
3673 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
3675 (InitCoreTypes): Update accordingly.
3677 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
3678 so we can quickly store the state.
3680 (ApplyAttributes): Set the correct implementation flags
3681 for InternalCall methods.
3683 2001-12-29 Miguel de Icaza <miguel@ximian.com>
3685 * expression.cs (EmitCall): if a method is not virtual, then do
3686 not use callvirt on it.
3688 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
3689 user defined stuff) requires the use of stobj, which takes an
3690 address on the stack instead of an array and an index. So emit
3691 the Ldelema operation for it.
3693 (EmitStoreOpcode): Use stobj for valuetypes.
3695 (UnaryMutator.EmitCode): Use the right 1 value depending on
3696 whether we are dealing with int64/uint64, float or doubles.
3698 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
3699 constructors that I implemented last night.
3701 (Constructor.IsDefault): Fix to work properly for static
3704 * cs-parser.jay (CheckDef): report method signature errors.
3705 Update error number 103 to be 132.
3707 * decl.cs: New AdditionResult enumeration value: MethodExists.
3708 Although we do this check for methods later on in the semantic
3709 analysis, catching repeated default constructors is so easy that
3710 we catch these here.
3712 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
3715 (ParameterReference.EmitAssign, Emit): handle
3718 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
3719 (ArrayAccess.EmitStoreOpcode): ditto.
3721 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
3723 * expression.cs (MakeByteBlob): Complete all the missing types
3724 (uint, short, ushort, byte, sbyte)
3726 * class.cs: Only init instance field initializers on instance
3729 Rename `constructors' to instance_constructors.
3731 (TypeContainer.AddConstructor): Only add constructors to the list
3732 if it is not static.
3734 Make sure that we handle default_static_constructor independently
3735 everywhere where we handle instance_constructors
3737 2001-12-28 Miguel de Icaza <miguel@ximian.com>
3739 * class.cs: Do not lookup or create a base initializer for a
3742 (ConstructorInitializer.Resolve): use the proper type to lookup
3745 * cs-parser.jay: Report error 1585 (modifiers between type and name).
3747 * enum.cs, interface.cs: Remove CloseType, this is taken care by
3750 * decl.cs: CloseType is now an virtual method, the default
3751 implementation just closes this type.
3753 2001-12-28 Ravi Pratap <ravi@ximian.com>
3755 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
3756 to PreserveSig by default. Also emit HideBySig on such methods.
3758 Basically, set the defaults to standard values.
3760 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
3761 argument, if candidate is better, it can't be worse than the best !
3763 (Invocation): Re-write bits to differentiate between methods being
3764 applicable in their expanded form and their normal form - for params
3767 Get rid of use_standard everywhere as only standard conversions are allowed
3768 in overload resolution.
3770 More spec conformance.
3772 2001-12-27 Miguel de Icaza <miguel@ximian.com>
3774 * driver.cs: Add --timestamp, to see where the compiler spends
3777 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
3778 `this' in static code.
3780 (SimpleName.DoResolve): Implement in terms of a helper function
3781 that allows static-references to be passed upstream to
3784 (Expression.ResolveWithSimpleName): Resolve specially simple
3785 names when called by MemberAccess to implement the special
3788 (Expression.ImplicitReferenceConversion): Handle conversions from
3789 Null to reference types before others, as Null's type is
3792 * expression.cs (Invocation.EmitCall): Handle the special case of
3793 calling methods declared on a reference type from a ValueType
3794 (Base classes System.Object and System.Enum)
3796 (MemberAccess.Resolve): Only perform lookups on Enumerations if
3797 the left hand side is a TypeExpr, not on every enumeration.
3799 (Binary.Resolve): If types are reference types, then do a cast to
3800 object on operators != and == of both arguments.
3802 * typemanager.cs (FindMembers): Extract instance and static
3803 members if requested.
3805 * interface.cs (PopulateProperty): Use void_type instead of null
3806 as the return type for the setter method.
3808 (PopulateIndexer): ditto.
3810 2001-12-27 Ravi Pratap <ravi@ximian.com>
3812 * support.cs (ReflectionParameters): Fix minor bug where we
3813 were examining the wrong parameter for the ParamArray attribute.
3815 Cope with requests for the type of the parameter at position
3816 greater than the params parameter's. We now return the element
3817 type of the params array as that makes more sense.
3819 * expression.cs (Invocation.IsParamsMethodApplicable): Update
3820 accordingly as we no longer have to extract the element type
3823 (Invocation.OverloadResolve): Update.
3825 2001-12-27 Miguel de Icaza <miguel@ximian.com>
3827 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
3828 against IEnumerator, test whether the return value is a descendant
3829 of the IEnumerator interface.
3831 * class.cs (Indexer.Define): Use an auxiliary method to implement
3832 the other bits of the method definition. Begin support for
3833 explicit interface implementation.
3835 (Property.DefineMethod): Use TypeManager.void_type instead of null
3836 for an empty return value.
3838 2001-12-26 Miguel de Icaza <miguel@ximian.com>
3840 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
3841 dealing with a FieldExpr which is composed of a FieldBuilder, in
3842 the code path we did extract the constant, but we should have
3843 obtained the underlying value to be able to cast it (otherwise we
3844 end up in an infinite loop, this is what Ravi was running into).
3846 (ArrayCreation.UpdateIndices): Arrays might be empty.
3848 (MemberAccess.ResolveMemberAccess): Add support for section
3849 14.5.4.1 that deals with the special case of E.I when E is a type
3850 and something else, that I can be a reference to a static member.
3852 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
3853 handle a particular array type to create byte blobs, it is just
3854 something we dont generate byteblobs for.
3856 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
3859 * location.cs (Push): remove the key from the hashtable that we
3860 are about to add. This happens for empty files.
3862 * driver.cs: Dispose files after we have parsed them.
3864 (tokenize): new function that only runs the tokenizer on its
3865 input, for speed testing.
3867 2001-12-26 Ravi Pratap <ravi@ximian.com>
3869 * class.cs (Event.Define): Define the private field only if there
3870 are no accessors defined.
3872 * expression.cs (ResolveMemberAccess): If there is no associated
3873 field with the event, that means we have an event defined with its
3874 own accessors and we should flag error cs0070 since transforming
3875 ourselves into a field is not valid in that case.
3877 * ecore.cs (SimpleName.DoResolve): Same as above.
3879 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
3880 and charset to sane values.
3882 2001-12-25 Ravi Pratap <ravi@ximian.com>
3884 * assign.cs (DoResolve): Perform check on events only if they
3885 are being accessed outside the declaring type.
3887 * cs-parser.jay (event_declarations): Update rules to correctly
3888 set the type of the implicit parameter etc.
3890 (add_accessor, remove_accessor): Set current local parameters.
3892 * expression.cs (Binary): For delegate addition and subtraction,
3893 cast the return value from the method into the appropriate delegate
3896 2001-12-24 Ravi Pratap <ravi@ximian.com>
3898 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
3899 of these as the workaround is unnecessary.
3901 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
3902 delegate data - none of that is needed at all.
3904 Re-write bits to extract the instance expression and the delegate method
3907 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
3910 * attribute.cs (ApplyAttributes): New method to take care of common tasks
3911 of attaching attributes instead of duplicating code everywhere.
3913 * everywhere : Update code to do attribute emission using the above method.
3915 2001-12-23 Miguel de Icaza <miguel@ximian.com>
3917 * expression.cs (IsParamsMethodApplicable): if there are not
3918 parameters, return immediately.
3920 * ecore.cs: The 0 literal can be implicity converted to an enum
3923 (SimpleName.DoResolve): First lookup the type, then lookup the
3926 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
3927 want to get its address. If the InstanceExpression is not
3928 addressable, store the result in a temporary variable, then get
3931 * codegen.cs: Only display 219 errors on warning level or above.
3933 * expression.cs (ArrayAccess): Make it implement the
3934 IMemoryLocation interface.
3936 (Binary.DoResolve): handle the operator == (object a, object b)
3937 and operator != (object a, object b) without incurring into a
3938 BoxedCast (because 5 != o should never be performed).
3940 Handle binary enumerator operators.
3942 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
3943 value type, otherwise use Ldelem_ref.
3945 Use precomputed names;
3947 (AddressOf): Implement address of
3949 * cs-parser.jay (labeled_statement): Fix recursive block
3950 addition by reworking the production.
3952 * expression.cs (New.DoEmit): New has a special case:
3954 If we are dealing with a ValueType, we have a few
3955 situations to deal with:
3957 * The target of New is a ValueType variable, that is
3958 easy, we just pass this as the variable reference
3960 * The target of New is being passed as an argument,
3961 to a boxing operation or a function that takes a
3964 In this case, we need to create a temporary variable
3965 that is the argument of New.
3968 2001-12-23 Ravi Pratap <ravi@ximian.com>
3970 * rootcontext.cs (LookupType): Check that current_type is not null before
3971 going about looking at nested types.
3973 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
3974 not implement the IAssignMethod interface any more.
3976 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
3977 where we tranform them into FieldExprs if they are being resolved from within
3980 * ecore.cs (SimpleName.DoResolve): Do the same here.
3982 * assign.cs (DoResolve, Emit): Clean up code considerably.
3984 * ../errors/bug10.cs : Add.
3986 * ../errors/cs0070.cs : Add.
3988 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
3990 * assign.cs : Get rid of EventIsLocal everywhere.
3992 2001-12-23 Miguel de Icaza <miguel@ximian.com>
3994 * ecore.cs (ConvertIntLiteral): finished the implementation.
3996 * statement.cs (SwitchLabel): Convert the value we are using as a
3997 key before looking up the table.
3999 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4001 * codegen.cs (EmitTopBlock): Require a Location argument now.
4003 * cs-parser.jay (constructor_declarator): We need to setup
4004 current_local_parameters before we parse the
4005 opt_constructor_initializer, to allow the variables to be bound
4006 to the constructor arguments.
4008 * rootcontext.cs (LookupType): First lookup nested classes in our
4009 class and our parents before we go looking outside our class.
4011 * expression.cs (ConstantFold): Extract/debox the values at the
4014 * rootcontext.cs (EmitCode): Resolve the constants first before we
4015 resolve the types. This is not really needed, but it helps debugging.
4017 * statement.cs: report location.
4019 * cs-parser.jay: pass location to throw statement.
4021 * driver.cs: Small bug fix.
4023 * report.cs: Updated format to be 4-zero filled digits.
4025 2001-12-22 Ravi Pratap <ravi@ximian.com>
4027 * expression.cs (CheckIndices): Fix minor bug where the wrong
4028 variable was being referred to ;-)
4030 (DoEmit): Do not call EmitStaticInitializers when the
4031 underlying type is System.Object.
4033 2001-12-21 Ravi Pratap <ravi@ximian.com>
4035 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
4036 and do the usual workaround for SRE.
4038 * class.cs (MyEventBuilder.EventType): New member to get at the type
4039 of the event, quickly.
4041 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
4043 * assign.cs (Assign.DoResolve): Handle the case when the target
4044 is an EventExpr and perform the necessary checks.
4046 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
4049 (SimpleName.MemberStaticCheck): Include check for EventExpr.
4051 (EventExpr): Set the type in the constructor itself since we
4052 are meant to be born fully resolved.
4054 (EventExpr.Define): Revert code I wrote earlier.
4056 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
4057 instance expression is null. The instance expression is a This in that case
4058 or a null, depending on whether it is a static method or not.
4060 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
4061 refers to more than one method.
4063 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
4064 and accordingly flag errors.
4066 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4068 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
4070 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4072 * location.cs (ToString): Provide useful rutine.
4074 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4076 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
4077 objects, return the actual integral boxed.
4079 * statement.cs (SwitchLabel): define an ILLabel for each
4082 (Switch.CheckSwitch): If the value is a Literal, extract
4083 the underlying literal.
4085 Also in the unused hashtable we had, add the SwitchLabel so we can
4086 quickly look this value up.
4088 * constant.cs: Implement a bunch of new constants. Rewrite
4089 Literal based on this. Made changes everywhere to adapt to this.
4091 * expression.cs (Expression.MakeByteBlob): Optimize routine by
4092 dereferencing array only once, and also copes with enumrations.
4094 bytes are two bytes wide, not one.
4096 (Cast): Perform constant conversions.
4098 * ecore.cs (TryImplicitIntConversion): Return literals instead of
4099 wrappers to the literals here.
4101 * expression.cs (DoNumericPromotions): long literals can converted
4102 to ulong implicity (this is taken care of elsewhere, but I was
4105 * ecore.cs (Expression.Literalize): Make the return type Literal,
4106 to improve type checking.
4108 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
4110 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4112 * literal.cs: Revert code from ravi that checked the bounds. The
4113 bounds are sane by the definition of the type itself.
4115 * typemanager.cs: Fix implementation of ImplementsInterface. We
4116 need to actually look up in our parent hierarchy for interfaces
4119 * const.cs: Use the underlying type for enumerations
4121 * delegate.cs: Compute the basename for the delegate creation,
4122 that should fix the delegate test case, and restore the correct
4123 Type Lookup semantics in rootcontext
4125 * rootcontext.cs: Revert Ravi's last patch. The correct way of
4126 referencing a nested type with the Reflection API is using the "+"
4129 * cs-parser.jay: Do not require EOF token at the end.
4131 2001-12-20 Ravi Pratap <ravi@ximian.com>
4133 * rootcontext.cs (LookupType): Concatenate type names with
4134 a '.' instead of a '+' The test suite passes again.
4136 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
4137 field of the enumeration.
4139 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
4140 the case when the member is an EventExpr.
4142 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
4143 static has an associated instance expression.
4145 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
4147 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
4149 * class.cs (Event.Define): Register event and perform appropriate checks
4152 We define the Add and Remove methods even if the use provides none because
4153 in that case, we provide default implementations ourselves.
4155 Define a private field of the type of the event. This is done by the CSC compiler
4156 and we should be doing it too ;-)
4158 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
4159 More methods we use in code we generate.
4161 (multicast_delegate_type, delegate_type): Two separate types since the distinction
4164 (InitCoreTypes): Update accordingly for the above.
4166 * class.cs (Event.Emit): Generate code for default accessors that we provide
4168 (EmitDefaultMethod): Do the job in the above.
4170 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
4173 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4175 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
4176 builders even if we were missing one.
4178 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
4179 pass the Basename as our class name instead of the Name. The
4180 basename will be correctly composed for us.
4182 * parameter.cs (Paramters): Now takes a Location argument.
4184 * decl.cs (DeclSpace.LookupType): Removed convenience function and
4185 make all the code call directly LookupType in RootContext and take
4186 this chance to pass the Location information everywhere.
4188 * Everywhere: pass Location information.
4190 2001-12-19 Miguel de Icaza <miguel@ximian.com>
4192 * class.cs (Constructor.Define): Updated way of detecting the
4193 length of the parameters.
4195 (TypeContainer.DefineType): Use basename as the type name for
4198 (TypeContainer.Define): Do not recursively define types here, as
4199 definition is taken care in order by the RootContext.
4201 * tree.cs: Keep track of namespaces in a per-file basis.
4203 * parameter.cs (Parameter.ComputeSignature): Update to use
4206 (Parameters.GetSignature): ditto.
4208 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
4209 instead of a TypeContainer.
4211 (Interface.SemanticAnalysis): Use `this' instead of our parent to
4212 resolve names. Because we need to be resolve in our context, not
4215 * driver.cs: Implement response files.
4217 * class.cs (TypeContainer.DefineType): If we are defined, do not
4220 (Event.Emit): Emit the code for add/remove handlers.
4221 (Event.Define): Save the MethodBuilders for add/remove.
4223 * typemanager.cs: Use pair here too.
4225 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
4226 DictionaryEntry requires the first argument to be non-null.
4228 (enum_declaration): Compute full name for registering the
4231 (delegate_declaration): Instead of using
4232 formal_parameter_list, use opt_formal_parameter_list as the list
4235 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
4236 (EventParsing): New property that controls whether `add' and
4237 `remove' are returned as tokens or identifiers (for events);
4239 2001-12-19 Ravi Pratap <ravi@ximian.com>
4241 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
4242 use MyEventBuilder only and let it wrap the real builder for us.
4244 (MyEventBuilder): Revamp constructor etc.
4246 Implement all operations that we perform on EventBuilder in precisely the same
4249 (FindMembers): Update to use the EventBuilder member.
4251 (Event.Emit): Update accordingly.
4253 2001-12-18 Ravi Pratap <ravi@ximian.com>
4255 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
4256 by calling the appropriate methods.
4258 (GetCustomAttributes): Make stubs as they cannot possibly do anything
4261 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
4263 2001-12-17 Ravi Pratap <ravi@ximian.com>
4265 * delegate.cs (Delegate.Populate): Check that the return type
4266 and various parameters types are indeed accessible.
4268 * class.cs (Constructor.Define): Same here.
4270 (Field.Define): Ditto.
4272 (Event.Define): Ditto.
4274 (Operator.Define): Check that the underlying Method defined itself
4275 correctly - so it's MethodBuilder should not be null.
4277 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
4278 expression happens to be null.
4280 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
4281 members but as of now we don't seem to be able to do anything really useful with it.
4283 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
4284 not the EventBuilder.
4286 2001-12-18 Miguel de Icaza <miguel@ximian.com>
4288 * cs-tokenizer.cs: Add support for defines.
4289 Add support for #if, #elif, #else, #endif
4291 (eval_var): evaluates a variable.
4292 (eval): stubbed for evaluating functions.
4294 * cs-parser.jay: Pass the defines information
4296 * driver.cs: Add --define command line option.
4298 * decl.cs: Move MemberCore here.
4300 Make it the base class for DeclSpace. This allows us to catch and
4301 report 108 and 109 for everything now.
4303 * class.cs (TypeContainer.Define): Extract all the members
4304 before populating and emit the warning 108 (new keyword required
4305 to override) instead of having each member implement this.
4307 (MemberCore.Define): New abstract method, we will be using this in
4308 the warning reporting engine in Populate.
4310 (Operator.Define): Adjust to new MemberCore protocol.
4312 * const.cs (Const): This does not derive from Expression, it is a
4313 temporary object we use to create fields, it is a MemberCore.
4315 * class.cs (Method.Define): Allow the entry point to be in a
4318 * driver.cs: Rewrite the argument handler to clean it up a bit.
4320 * rootcontext.cs: Made it just an auxiliary namespace feature by
4321 making everything static.
4323 * driver.cs: Adapt code to use RootContext type name instead of
4326 * delegate.cs: Remove RootContext argument.
4328 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
4331 * class.cs (Event.Define): The lookup can fail.
4333 * cs-tokenizer.cs: Begin implementation of pre-procesor.
4335 * expression.cs: Resolve the this instance before invoking the code.
4337 2001-12-17 Miguel de Icaza <miguel@ximian.com>
4339 * cs-parser.jay: Add a production in element_access that allows
4340 the thing to become a "type" reference. This way we can parse
4341 things like "(string [])" as a type.
4343 Note that this still does not handle the more complex rules of
4347 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
4349 * ecore.cs: (CopyNewMethods): new utility function used to
4350 assemble the list of methods from running FindMembers.
4352 (MemberLookup): Rework FindMembers so that
4354 2001-12-16 Miguel de Icaza <miguel@ximian.com>
4356 * class.cs (TypeContainer): Remove Delegates who fail to be
4359 * delegate.cs (Populate): Verify that we dont get null return
4360 values. TODO: Check for AsAccessible.
4362 * cs-parser.jay: Use basename to emit error 574 (destructor should
4363 have the same name as container class), not the full name.
4365 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
4366 possible representation.
4368 Also implements integer type suffixes U and L.
4370 2001-12-15 Miguel de Icaza <miguel@ximian.com>
4372 * expression.cs (ArrayCreation.DoResolve): We need to do the
4373 argument resolution *always*.
4375 * decl.cs: Make this hold the namespace. Hold the root context as
4377 (LookupType): Move here.
4379 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
4381 * location.cs (Row, Name): Fixed the code, it was always returning
4382 references to the first file.
4384 * interface.cs: Register properties defined through interfaces.
4386 * driver.cs: Add support for globbing on the command line
4388 * class.cs (Field): Make it derive from MemberCore as well.
4391 2001-12-15 Ravi Pratap <ravi@ximian.com>
4393 * class.cs (Event::Define): Check that the type of the event is a delegate
4394 type else flag error #66.
4396 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
4399 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
4400 values of EntryPoint, CharSet etc etc.
4402 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
4404 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
4405 be null and we should ignore this. I am not sure if this is really clean. Apparently,
4406 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
4407 which needs this to do its work.
4409 * ../errors/cs0066.cs : Add.
4411 2001-12-14 Miguel de Icaza <miguel@ximian.com>
4413 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
4416 * class.cs: (MethodSignature.MethodSignature): Removed hack that
4417 clears out the parameters field.
4418 (MemberSignatureCompare): Cleanup
4420 (MemberCore): New base class used to share code between MethodCore
4423 (RegisterRequiredImplementations) BindingFlags.Public requires
4424 either BindingFlags.Instace or Static. Use instance here.
4426 (Property): Refactored code to cope better with the full spec.
4428 * parameter.cs (GetParameterInfo): Return an empty array instead
4431 * class.cs (Property): Abstract or extern properties have no bodies.
4433 * parameter.cs (GetParameterInfo): return a zero-sized array.
4435 * class.cs (TypeContainer.MethodModifiersValid): Move all the
4436 method modifier validation to the typecontainer so we can reuse
4439 (MethodCore.ParameterTypes): return an empty sized array of types.
4441 (Property.Define): Test property modifier validity.
4443 Add tests for sealed/override too.
4445 (Method.Emit): abstract or extern methods have no bodies.
4447 2001-12-14 Ravi Pratap <ravi@ximian.com>
4449 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
4452 (Method::Define, ::Emit): Modify accordingly.
4454 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
4456 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
4458 * makefile: Pass in /unsafe.
4460 2001-12-13 Miguel de Icaza <miguel@ximian.com>
4462 * class.cs (MakeKey): Kill routine.
4464 * class.cs (TypeContainer.Define): Correctly define explicit
4465 method implementations (they require the full interface name plus
4468 * typemanager.cs: Deply the PtrHashtable here and stop using the
4469 lame keys. Things work so much better.
4471 This of course broke everyone who depended on `RegisterMethod' to
4472 do the `test for existance' test. This has to be done elsewhere.
4474 * support.cs (PtrHashtable): A hashtable that avoid comparing with
4475 the object stupid Equals method (because, that like fails all over
4476 the place). We still do not use it.
4478 * class.cs (TypeContainer.SetRequiredInterface,
4479 TypeContainer.RequireMethods): Killed these two routines and moved
4480 all the functionality to RegisterRequiredImplementations.
4482 (TypeContainer.RegisterRequiredImplementations): This routine now
4483 registers all the implementations required in an array for the
4484 interfaces and abstract methods. We use an array of structures
4485 which can be computed ahead of time to reduce memory usage and we
4486 also assume that lookups are cheap as most classes will not
4487 implement too many interfaces.
4489 We also avoid creating too many MethodSignatures.
4491 (TypeContainer.IsInterfaceMethod): Update and optionally does not
4492 clear the "pending" bit if we find that there are problems with
4495 (TypeContainer.VerifyPendingMethods): Update to report errors of
4496 methods that look like implementations but are not.

4503 * typemanager.cs: Keep track of the parameters here instead of
4504 being a feature of the TypeContainer.
4506 * class.cs: Drop the registration of parameters here, as
4507 InterfaceMethods are also interface declarations.

4510 the TypeContainer. This code was buggy.
4512 * interface.cs: Full registation here.
4514 2001-12-11 Miguel de Icaza <miguel@ximian.com>
4516 * expression.cs: Remove reducer for binary expressions, it can not

4585 * statement.cs (Using.EmitLocalVariableDecls): Split the
4586 localvariable handling of the using statement.
4588 (Block.EmitMeta): Keep track of variable count across blocks. We
4589 were reusing slots on separate branches of blocks.
4591 (Try.Emit): Emit the general code block, we were not emitting it.
4593 Check the type of the declaration to be an IDisposable or
4594 something that can be implicity converted to it.

4617 properly generate the overflow opcodes.
4619 2001-12-04 Miguel de Icaza <miguel@ximian.com>
4621 * statement.cs: The correct type for the EmptyExpression is the
4622 element_type, not the variable type. Ravi pointed this out.
4624 2001-12-04 Ravi Pratap <ravi@ximian.com>
4626 * class.cs (Method::Define): Handle PInvoke methods specially
4627 by using DefinePInvokeMethod instead of the usual one.
4629 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
4630 above to do the task of extracting information and defining the method.
4632 2001-12-04 Ravi Pratap <ravi@ximian.com>

4719 * enum.cs (LookupEnumValue): Re-write various bits, return an object value
4720 instead of a Literal - much easier.
4722 (EnumInTransit): Remove - utterly useless :-)
4724 (Populate): Re-write bits - remove duplicate code etc. The code is much neater now.
4726 * expression.cs (MemberLookup): Cope with user-defined enums when they are in transit.

4826 (Bounds): Make it a hashtable to prevent the same dimension being
4827 recorded for every element in that dimension.

4876 2001-11-22 Miguel de Icaza <miguel@ximian.com>
4878 * statement.cs (If.Emit): Fix a bug that generated incorrect code
4879 on If. Basically, we have to return `true' (ie, we do return to

4883 short-circuit operators, handle them as short circuit operators.

4886 (Cast.Cast): Take an expression as the target type.
4888 * cs-parser.jay (cast_expression): Remove old hack that only
4889 allowed a limited set of types to be handled. Now we take a
4890 unary_expression and we resolve to a type during semantic
4893 Use the grammar productions from Rhys to handle casts (this is
4894 not complete like Rhys syntax yet, we fail to handle that corner
4895 case that C# has regarding (-x), but we will get there.
4897 2001-11-22 Ravi Pratap <ravi@ximian.com>
4899 * class.cs (EmitFieldInitializer): Take care of the case when we have a
4900 field which is an array type.

4906 (everywhere): Use the above appropriately.
4908 * cs-parser.jay (for_statement): Update for array initialization while
4909 declaring variables.
4911 * ecore.cs : The error message was correct, it's the variable's names that

4914 (MemberAccess::DoResolve): Fix the code which handles Enum literals to set
4915 the correct type etc.
4917 (ConvertExplicit): Handle Enum types by examining the underlying type.
4919 2001-11-21 Ravi Pratap <ravi@ximian.com>

4932 BindingFlags.Instance as well
4934 * ecore.cs (Expression.TryImplicitIntConversion): Wrap the result
4935 implicit int literal conversion in an empty cast so that we
4936 propagate the right type upstream.
4938 (UnboxCast): new class used to unbox value types.
4939 (Expression.ConvertExplicit): Add explicit type conversions done
4942 (Expression.ImplicitNumericConversion): Oops, forgot to test for
4943 the target type before applying the implicit LongLiterals to ULong
4946 2001-11-21 Miguel de Icaza <miguel@ximian.com>
4948 * cs-parser.jay (for_statement): Reworked the way For works: now
4949 we declare manually any variables that are introduced in
4950 for_initializer to solve the problem of having out-of-band code
4951 emition (that is what got for broken).
4953 (declaration_statement): Perform the actual variable declaration
4954 that used to be done in local_variable_declaration here.
4956 (local_variable_declaration): Do not declare anything, just pass
4957 the information on a DictionaryEntry
4959 2001-11-20 Ravi Pratap <ravi@ximian.com>
4961 * expression.cs (ArrayCreation::CheckIndices): The story continues :-) Complete

5024 we can use this elsewhere.
5026 * statement.cs: Finish implementation of foreach for single
5029 * cs-parser.jay: Use an out-of-band stack to pass information
5030 around, I wonder why I need this.
5032 foreach_block: Make the new foreach_block the current_block.
5034 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
5035 function used to return a static Parameters structure. Used for
5036 empty parameters, as those are created very frequently.
5038 * cs-parser.jay, class.cs: Use GetEmptyReadOnlyParameters
5040 2001-11-15 Ravi Pratap <ravi@ximian.com>
5042 * interface.cs : Default modifier is private, not public. The
5043 make verify test passes again.
5045 2001-11-15 Ravi Pratap <ravi@ximian.com>
5047 * support.cs (ReflectionParameters): Fix logic to determine
5048 whether the last parameter is a params one. Test 9 passes again.

5054 of $$ to get at the location.
5056 (indexer_declaration): Similar stuff.
5060 * class.cs (Property): Register parameters for the Get and Set methods

5081 2001-11-09 Miguel de Icaza <miguel@ximian.com>
5083 * enum.cs (Enum.Emit): Delay the lookup of loc until we run into

5102 way we can report the error correctly for missing return values.
5104 * class.cs (Method.Emit): Clean up.
5106 * expression.cs (Argument.Resolve): Take another argument: the
5107 location where this argument is used. Notice that this is not
5108 part of the "Argument" class as to reduce the size of the
5109 structure (we know the approximate location anyways).
5111 Test if the argument is a variable-reference, if not, then
5112 complain with a 206.
5114 (Argument.Emit): Emit addresses of variables.
5116 (Argument.FullDesc): Simplify.
5118 (Invocation.DoResolve): Update for Argument.Resolve.
5120 (ElementAccess.DoResolve): ditto.

5143 2001-11-13 Miguel de Icaza <miguel@ximian.com>
5145 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
5146 enumerations that are used in heavily used structures derive from
5147 byte in a laughable and pathetic attempt to reduce memory usage.
5148 This is the kind of pre-optimzations that you should not do at
5149 home without adult supervision.
5151 * expression.cs (UnaryMutator): New class, used to handle ++ and
5152 -- separatedly from the other unary operators. Cleans up the
5153 code, and kills the ExpressionStatement dependency in Unary.
5155 (Unary): Removed `method' and `Arguments' from this class, making
5156 it smaller, and moving it all to SimpleCall, so I can reuse this
5157 code in other locations and avoid creating a lot of transient data
5158 strucutres when not required.
5160 * cs-parser.jay: Adjust for new changes.
5162 2001-11-11 Miguel de Icaza <miguel@ximian.com>
5164 * enum.cs (Enum.Populate): If there is a failure during
5167 * cs-parser.jay (opt_enum_base): we used to catch type errors

5910 (IsDelegateType): Implement helper method.
5912 * delegate.cs (DefineDelegate): Use AddDelegateType instead of AddUserType.
5914 * expression.cs (New::DoResolve): Check if we are trying to instantiate a delegate type
5915 and accordingly handle it.
5917 * delegate.cs (Populate): Take TypeContainer argument.
5918 Implement bits to define the Invoke method. However, I still haven't figured out
5919 how to take care of the native int bit :-(
5921 * cs-parser.jay (delegate_declaration): Fixed the bug that I had introduced :-)
5922 Qualify the name of the delegate, not its return type !
5924 * expression.cs (ImplicitReferenceConversion): Implement guts of implicit array
5927 (StandardConversionExists): Checking for array types turns out to be recursive.
5929 (ConvertReferenceExplicit): Implement array conversion.
5931 (ExplicitReferenceConversionExists): New method to determine precisely that :-)
5933 2001-10-12 Ravi Pratap <ravi@ximian.com>
5935 * cs-parser.jay (delegate_declaration): Store the fully qualified
5936 name as it is a type declaration.
5938 * delegate.cs (ReturnType, Name): Rename members to these. Make them
5941 (DefineDelegate): Renamed from Define. Does the same thing essentially,
5942 as TypeContainer::DefineType.
5944 (Populate): Method in which all the definition of the various methods (Invoke)
5947 (Emit): Emit any code, if necessary. I am not sure about this really, but let's
5950 (CloseDelegate): Finally creates the delegate.
5952 * class.cs (TypeContainer::DefineType): Update to define delegates.
5953 (Populate, Emit and CloseType): Do the same thing here too.
5955 * rootcontext.cs (ResolveTree, PopulateTypes, EmitCode, CloseTypes): Include
5956 delegates in all these operations.
5958 2001-10-14 Miguel de Icaza <miguel@ximian.com>
5960 * expression.cs: LocalTemporary: a new expression used to
5961 reference a temporary that has been created.
5963 * assign.cs: Handle PropertyAccess back here, so that we can
5964 provide the proper semantic access to properties.
5966 * expression.cs (Expression::ConvertReferenceExplicit): Implement
5967 a few more explicit conversions.
5969 * modifiers.cs: `NEW' modifier maps to HideBySig.
5971 * expression.cs (PropertyExpr): Make this into an
5972 ExpressionStatement, and support the EmitStatement code path.
5974 Perform get/set error checking, clean up the interface.
5976 * assign.cs: recognize PropertyExprs as targets, and if so, turn
5977 them into toplevel access objects.

5981 * expression.cs: PropertyExpr::PropertyExpr: use work around the
5984 * typemanager.cs: Keep track here of our PropertyBuilders again to
5985 work around lameness in SRE.
5987 2001-10-11 Miguel de Icaza <miguel@ximian.com>
5989 * expression.cs (LValue::LValueResolve): New method in the
5990 interface, used to perform a second resolution pass for LValues.
5992 (This::DoResolve): Catch the use of this in static methods.
5994 (This::LValueResolve): Implement.
5996 (This::Store): Remove warning, assigning to `this' in structures
5999 (Invocation::Emit): Deal with invocation of
6000 methods on value types. We need to pass the address to structure
6001 methods rather than the object itself. (The equivalent code to
6002 emit "this" for structures leaves the entire structure on the
6003 stack instead of a pointer to it).
6005 (ParameterReference::DoResolve): Compute the real index for the
6006 argument based on whether the method takes or not a `this' pointer
6007 (ie, the method is static).
6009 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store
6010 value types returned from functions when we need to invoke a
6011 method on the sturcture.
6014 2001-10-11 Ravi Pratap <ravi@ximian.com>
6016 * class.cs (TypeContainer::DefineType): Method to actually do the business of
6017 defining the type in the Modulebuilder or Typebuilder. This is to take
6018 care of nested types which need to be defined on the TypeBuilder using
6021 (TypeContainer::GetClassBases): Implement. Essentially the code from the
6022 methods in RootContext, only ported to be part of TypeContainer.
6024 (TypeContainer::GetInterfaceOrClass): Ditto.
6026 (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
6028 * interface.cs (Interface::DefineInterface): New method. Does exactly
6029 what RootContext.CreateInterface did earlier, only it takes care of nested types
6032 (Interface::GetInterfaces): Move from RootContext here and port.
6034 (Interface::GetInterfaceByName): Same here.
6036 * rootcontext.cs (ResolveTree): Re-write.

6040 * class.cs (TypeContainer::Populate): Populate nested types too.
6041 (TypeContainer::Emit): Emit nested members too.
6043 * typemanager.cs (AddUserType): Do not make use of the FullName property,
6044 instead just use the name argument passed in as it is already fully
6047 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
6048 to TypeContainer mapping to see if a type is user-defined.
6050 * class.cs (TypeContainer::CloseType): Implement.
6052 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
6053 the default constructor.
6055 (TypeContainer::Populate): Fix minor bug which led to creating default constructors
6058 (Constructor::IsDefault): Fix up logic to determine if it is the default constructor
6060 * interface.cs (CloseType): Create the type here.
6062 * rootcontext.cs (CloseTypes): Re-write to recursively close types by running through
6065 Remove all the methods which are now in TypeContainer.
6067 2001-10-10 Ravi Pratap <ravi@ximian.com>
6069 * delegate.cs (Define): Re-write bits to define the delegate
6072 2001-10-10 Miguel de Icaza <miguel@ximian.com>
6074 * makefile: Renamed the compiler to `mcs.exe' instead of compiler.exe
6076 * expression.cs (ImplicitReferenceConversion): handle null as well
6077 as a source to convert to any reference type.
6079 * statement.cs (Return): Perform any implicit conversions to
6080 expected return type.
6082 Validate use of return statement.
6084 * codegen.cs (EmitContext): Pass the expected return type here.
6086 * class.cs (Method, Constructor, Property): Pass expected return
6087 type to EmitContext.
6089 2001-10-09 Miguel de Icaza <miguel@ximian.com>
6091 * expression.cs: Make DoResolve take an EmitContext instead of a
6094 Replaced `l' and `location' for `loc', for consistency.
6096 (Error, Warning): Remove unneeded Tc argument.
6098 * assign.cs, literal.cs, constant.cs: Update to new calling
6101 * codegen.cs: EmitContext now contains a flag indicating whether
6102 code is being generated in a static method or not.
6104 * cs-parser.jay: DecomposeQI, new function that replaces the old
6105 QualifiedIdentifier. Now we always decompose the assembled
6106 strings from qualified_identifier productions into a group of
6109 2001-10-08 Miguel de Icaza <miguel@ximian.com>
6111 * rootcontext.cs: Deal with field-less struct types correctly now
6112 by passing the size option to Define Type.
6114 * class.cs: Removed hack that created one static field.
6116 2001-10-07 Miguel de Icaza <miguel@ximian.com>
6118 * statement.cs: Moved most of the code generation here.
6120 2001-10-09 Ravi Pratap <ravi@ximian.com>
6122 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
6125 (ElementAccess): Remove useless bits for now - keep checks as the spec
6128 2001-10-08 Ravi Pratap <ravi@ximian.com>
6130 * expression.cs (ElementAccess::DoResolve): Remove my crap code
6131 and start performing checks according to the spec.
6133 2001-10-07 Ravi Pratap <ravi@ximian.com>
6135 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
6136 rank_specifiers instead.
6138 (rank_specifiers): Change the order in which the rank specifiers are stored
6140 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
6142 * expression.cs (ElementAccess): Implement the LValue interface too.
6144 2001-10-06 Ravi Pratap <ravi@ximian.com>
6146 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
6147 except that user defined conversions are not included.
6149 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
6150 perform the conversion of the return type, if necessary.
6152 (New::DoResolve): Check whether we are creating an array or an object
6153 and accordingly do the needful.
6155 (New::Emit): Same here.
6157 (New::DoResolve): Implement guts of array creation.
6159 (New::FormLookupType): Helper function.
6161 2001-10-07 Miguel de Icaza <miguel@ximian.com>
6163 * codegen.cs: Removed most of the code generation here, and move the
6164 corresponding code generation bits to the statement classes.
6166 Added support for try/catch/finalize and throw.
6168 * cs-parser.jay: Added support for try/catch/finalize.
6170 * class.cs: Catch static methods having the flags override,
6171 virtual or abstract.
6173 * expression.cs (UserCast): This user cast was not really doing
6174 what it was supposed to do. Which is to be born in fully resolved
6175 state. Parts of the resolution were being performed at Emit time!
6179 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6181 * expression.cs: Implicity convert the result from UserCast.
6183 2001-10-05 Ravi Pratap <ravi@ximian.com>
6185 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
6186 prevented it from working correctly.
6188 (ConvertExplicit): Make the first try, a call to ConvertImplicitStandard, not
6189 merely ConvertImplicit.
6191 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6193 * typemanager.cs: Make the LookupTypeContainer function static,
6194 and not per-instance.
6196 * class.cs: Make static FindMembers (the one that takes a Type
6199 * codegen.cs: Add EmitForeach here.
6201 * cs-parser.jay: Make foreach a toplevel object instead of the
6202 inline expansion, as we need to perform semantic analysis on it.
6204 2001-10-05 Ravi Pratap <ravi@ximian.com>
6206 * expression.cs (Expression::ImplicitUserConversion): Rename to
6207 UserDefinedConversion.
6209 (Expression::UserDefinedConversion): Take an extra argument specifying
6210 whether we look for explicit user conversions too.
6212 (Expression::ImplicitUserConversion): Make it a call to UserDefinedConversion.

6221 * expression.cs (Cast): Record location info.
6223 (Expression::ConvertExplicit): Take location argument.
6225 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
6226 to determine if we are doing explicit conversions.
6228 (UserCast::Emit): Update accordingly.
6230 (Expression::ConvertExplicit): Report an error if everything fails.
6232 * ../errors/cs0030.cs : Add.
6234 2001-10-04 Miguel de Icaza <miguel@ximian.com>
6236 * modifiers.cs: If the ABSTRACT keyword is present, also set the
6237 virtual and newslot bits.
6239 * class.cs (TypeContainer::RegisterRequiredImplementations):
6240 Record methods we need.
6242 (TypeContainer::MakeKey): Helper function to make keys for
6243 MethodBases, since the Methodbase key is useless.
6245 (TypeContainer::Populate): Call RegisterRequiredImplementations
6246 before defining the methods.
6248 Create a mapping for method_builders_to_methods ahead of time
6249 instead of inside a tight loop.
6251 (::RequireMethods): Accept an object as the data to set into the
6252 hashtable so we can report interface vs abstract method mismatch.
6254 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6256 * report.cs: Make all of it static.
6258 * rootcontext.cs: Drop object_type and value_type computations, as
6259 we have those in the TypeManager anyways.
6261 Drop report instance variable too, now it is a global.
6263 * driver.cs: Use try/catch on command line handling.
6265 Add --probe option to debug the error reporting system with a test
6268 * report.cs: Add support for exiting program when a probe
6269 condition is reached.
6271 2001-10-03 Ravi Pratap <ravi@ximian.com>
6273 * expression.cs (Binary::DoNumericPromotions): Fix the case when
6274 we do a forcible conversion regardless of type, to check if
6275 ForceConversion returns a null.
6277 (Binary::error19): Use location to report error.
6279 (Unary::error23): Use location here too.
6281 * ../errors/cs0019.cs : Check in.
6283 * ../errors/cs0023.cs : Check in.
6285 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
6286 case of a non-null MethodInfo object with a length of 0 !
6288 (Binary::ResolveOperator): Flag error if overload resolution fails to find
6289 an applicable member - according to the spec :-)
6290 Also fix logic to find members in base types.
6292 (Unary::ResolveOperator): Same here.
6294 (Unary::report23): Change name to error23 and make first argument a TypeContainer
6295 as I was getting thoroughly confused between this and error19 :-)
6297 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
6298 (::FindMostEncompassedType): Implement.
6299 (::FindMostEncompassingType): Implement.
6300 (::StandardConversionExists): Implement.
6302 (UserImplicitCast): Re-vamp. We now need info about most specific
6303 source and target types so that we can do the necessary conversions.
6305 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
6306 mathematical union with no duplicates.
6308 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6310 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
6311 in order from base classes to child classes, so that we can in
6312 child classes look up in our parent for method names and
6313 attributes (required for handling abstract, virtual, new, override
6314 constructs: we need to instrospect our base class, and if we dont
6315 populate the classes in order, the introspection might be
6316 incorrect. For example, a method could query its parent before
6317 the parent has any methods and would determine that the parent has
6318 no abstract methods (while it could have had them)).
6320 (RootContext::CreateType): Record the order in which we define the
6323 2001-10-02 Miguel de Icaza <miguel@ximian.com>
6325 * class.cs (TypeContainer::Populate): Also method definitions can
6326 fail now, keep track of this.
6328 (TypeContainer::FindMembers): Implement support for
6329 DeclaredOnly/noDeclaredOnly flag.
6331 (Constructor::Emit) Return the ConstructorBuilder.
6333 (Method::Emit) Return the MethodBuilder.
6334 Check for abstract or virtual methods to be public.
6336 * rootcontext.cs (RootContext::CreateType): Register all the
6337 abstract methods required for the class to be complete and the
6338 interface methods that must be implemented.
6340 * cs-parser.jay: Report error 501 (method requires body if it is
6341 not marked abstract or extern).
6343 * expression.cs (TypeOf::Emit): Implement.
6345 * typemanager.cs: runtime_handle_type, new global type.
6347 * class.cs (Property::Emit): Generate code for properties.
6349 2001-10-02 Ravi Pratap <ravi@ximian.com>
6351 * expression.cs (Unary::ResolveOperator): Find operators on base type
6352 too - we now conform exactly to the spec.
6354 (Binary::ResolveOperator): Same here.
6356 * class.cs (Operator::Define): Fix minor quirk in the tests.
6358 * ../errors/cs0215.cs : Added.
6360 * ../errors/cs0556.cs : Added.
6362 * ../errors/cs0555.cs : Added.
6364 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6366 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
6367 single integer which is really efficient
6369 2001-10-01 Ravi Pratap <ravi@ximian.com>
6371 * expression.cs (Expression::ImplicitUserConversion): Use location
6372 even in the case when we are examining True operators.
6374 * class.cs (Operator::Define): Perform extensive checks to conform
6375 with the rules for operator overloading in the spec.
6377 * expression.cs (Expression::ImplicitReferenceConversion): Implement
6378 some of the other conversions mentioned in the spec.
6380 * typemanager.cs (array_type): New static member for the System.Array built-in
6383 (cloneable_interface): For System.ICloneable interface.
6385 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
6386 we start resolving the tree and populating types.
6388 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
6390 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6392 * expression.cs (Expression::ExprClassFromMemberInfo,
6393 Expression::Literalize): Create literal expressions from
6394 FieldInfos which are literals.
6396 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
6397 type casts, because they were wrong. The test suite in tests
6400 (ImplicitNumericConversion): ushort to ulong requires a widening
6403 Int32 constant to long requires widening cast as well.
6405 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
6406 for integers because the type on the stack is not i4.
6408 2001-09-30 Miguel de Icaza <miguel@ximian.com>
6410 * expression.cs (report118): require location argument.
6412 * parameter.cs: Do not dereference potential null value.
6414 * class.cs: Catch methods that lack the `new' keyword when
6415 overriding a name. Report warnings when `new' is used without
6416 anything being there to override.
6418 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
6420 * class.cs: Only add constructor to hashtable if it is non-null
6421 (as now constructors can fail on define).
6423 (TypeManager, Class, Struct): Take location arguments.
6425 Catch field instance initialization in structs as errors.
6427 accepting_filter: a new filter for FindMembers that is static so
6428 that we dont create an instance per invocation.
6430 (Constructor::Define): Catch errors where a struct constructor is
6433 * cs-parser.jay: Pass location information for various new
6436 * delegate.cs (Delegate): take a location argument.
6438 * driver.cs: Do not call EmitCode if there were problesm in the
6439 Definition of the types, as many Builders wont be there.
6441 * decl.cs (Decl::Decl): Require a location argument.
6443 * cs-tokenizer.cs: Handle properly hex constants that can not fit
6444 into integers, and find the most appropiate integer for it.
6446 * literal.cs: Implement ULongLiteral.
6448 * rootcontext.cs: Provide better information about the location of
6449 failure when CreateType fails.
6451 2001-09-29 Miguel de Icaza <miguel@ximian.com>
6453 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
6456 * expression.cs (Binary::CheckShiftArguments): Add missing type
6458 (Binary::ResolveOperator): Add type to the logical and and logical
6459 or, Bitwise And/Or and Exclusive Or code paths, it was missing
6462 (Binary::DoNumericPromotions): In the case where either argument
6463 is ulong (and most signed types combined with ulong cause an
6464 error) perform implicit integer constant conversions as well.
6466 2001-09-28 Miguel de Icaza <miguel@ximian.com>
6468 * expression.cs (UserImplicitCast): Method should always be
6470 (Invocation::BetterConversion): Simplified test for IntLiteral.
6472 (Expression::ImplicitNumericConversion): Split this routine out.
6473 Put the code that performs implicit constant integer conversions
6476 (Expression::Resolve): Become a wrapper around DoResolve so we can
6477 check eclass and type being set after resolve.
6479 (Invocation::Badness): Remove this dead function
6481 (Binary::ResolveOperator): Do not compute the expensive argumnets
6482 unless we have a union for it.
6484 (Probe::Emit): Is needs to do an isinst and then
6485 compare against null.
6487 (::CanConvert): Added Location argument. If the Location argument
6488 is null (Location.Null), then we do not report errors. This is
6489 used by the `probe' mechanism of the Explicit conversion. We do
6490 not want to generate an error for something that the user
6491 explicitly requested to be casted. But the pipeline for an
6492 explicit cast first tests for potential implicit casts.
6494 So for now, if the Location is null, it means `Probe only' to
6495 avoid adding another argument. Might have to revise this
6498 (ClassCast): New class used to type cast objects into arbitrary
6499 classes (used in Explicit Reference Conversions).
6501 Implement `as' as well.
6503 Reverted all the patches from Ravi below: they were broken:
6505 * The use of `level' as a mechanism to stop recursive
6506 invocations is wrong. That was there just to catch the
6507 bug with a strack trace but not as a way of addressing
6510 To fix the problem we have to *understand* what is going
6511 on and the interactions and come up with a plan, not
6512 just get things going.
6514 * The use of the type conversion cache that I proposed
6515 last night had an open topic: How does this work across
6516 protection domains. A user defined conversion might not
6517 be public in the location where we are applying the
6518 conversion, a different conversion might be selected
6519 (ie, private A->B (better) but public B->A (worse),
6520 inside A, A->B applies, but outside it, B->A will
6523 * On top of that (ie, even if the above is solved),
6524 conversions in a cache need to be abstract. Ie, `To
6525 convert from an Int to a Short use an OpcodeCast', not
6526 `To convert from an Int to a Short use the OpcodeCast on
6527 the variable 5' (which is what this patch was doing).
6529 2001-09-28 Ravi Pratap <ravi@ximian.com>
6531 * expression.cs (Invocation::ConversionExists): Re-write to use
6532 the conversion cache
6534 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
6535 cache all conversions done, not just user-defined ones.
6537 (Invocation::BetterConversion): The real culprit. Use ConversionExists
6538 to determine if a conversion exists instead of acutually trying to
6539 perform the conversion. It's faster too.
6541 (Expression::ConvertExplicit): Modify to use ConversionExists to check
6542 and only then attempt the implicit conversion.
6544 2001-09-28 Ravi Pratap <ravi@ximian.com>
6546 * expression.cs (ConvertImplicit): Use a cache for conversions
6547 already found. Check level of recursion and bail out if necessary.
6549 2001-09-28 Miguel de Icaza <miguel@ximian.com>
6551 * typemanager.cs (string_concat_string_string, string_concat_object_object):
6552 Export standard methods that we expect for string operations.
6554 * statement.cs (Block::UsageWarning): Track usage of variables and
6555 report the errors for not used variables.
6557 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
6560 2001-09-27 Miguel de Icaza <miguel@ximian.com>
6562 * codegen.cs: remove unnneded code
6564 * expression.cs: Removed BuiltinTypeAccess class
6566 Fix the order in which implicit conversions are
6569 The previous fixed dropped support for boxed conversions (adding a
6570 test to the test suite now)
6572 (UserImplicitCast::CanConvert): Remove test for source being null,
6573 that code is broken. We should not feed a null to begin with, if
6574 we do, then we should track the bug where the problem originates
6575 and not try to cover it up here.
6577 Return a resolved expression of type UserImplicitCast on success
6578 rather than true/false. Ravi: this is what I was talking about,
6579 the pattern is to use a static method as a "constructor" for
6582 Also, do not create arguments until the very last minute,
6583 otherwise we always create the arguments even for lookups that
6584 will never be performed.
6586 (UserImplicitCast::Resolve): Eliminate, objects of type
6587 UserImplicitCast are born in a fully resolved state.
6589 * typemanager.cs (InitCoreTypes): Init also value_type
6592 * expression.cs (Cast::Resolve): First resolve the child expression.
6594 (LValue): Add new method AddressOf to be used by
6597 Change the argument of Store to take an EmitContext instead of an
6598 ILGenerator, because things like FieldExpr need to be able to call
6599 their children expression to generate the instance code.
6601 (Expression::Error, Expression::Warning): Sugar functions for
6604 (Expression::MemberLookup): Accept a TypeContainer instead of a
6605 Report as the first argument.
6607 (Expression::ResolvePrimary): Killed. I still want to improve
6608 this as currently the code is just not right.
6610 (Expression::ResolveMemberAccess): Simplify, but it is still
6613 (Unary::Resolve): Catch errors in AddressOf operators.
6615 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
6616 index to a byte for the short-version, or the compiler will choose

6629 Error and Warning classes.
6631 * cs-parser.jay (member_access): Turn built-in access to types

6639 * expression.cs (ConvertImplicit): Do built-in conversions first.
6641 2001-09-27 Ravi Pratap <ravi@ximian.com>
6643 * expression.cs (UserImplicitCast::Resolve): Fix bug.
6645 2001-09-27 Ravi Pratap <ravi@ximian.com>

6659 overloading resolution. Use everywhere instead of cutting and pasting code.
6661 (Binary::ResolveOperator): Use MakeUnionSet.
6663 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
6664 we have to convert to bool types. Not complete yet.

6668 * typemanager.cs (TypeManager::CSharpName): support ushort.
6670 * expression.cs (Expression::TryImplicitIntConversion): Attempts
6671 to provide an expression that performsn an implicit constant int
6672 conversion (section 6.1.6).
6673 (Expression::ConvertImplicitRequired): Reworked to include
6674 implicit constant expression conversions.
6676 (Expression::ConvertNumericExplicit): Finished.
6678 (Invocation::Emit): If InstanceExpression is null, then it means
6679 that we perform a call on this.
6681 2001-09-26 Miguel de Icaza <miguel@ximian.com>
6683 * expression.cs (Unary::Emit): Remove some dead code.
6684 (Probe): Implement Resolve and Emit for `is'.
6685 (Expression::ConvertImplicitRequired): Attempt to do constant
6686 expression conversions here. Maybe should be moved to
6687 ConvertImplicit, but I am not sure.
6688 (Expression::ImplicitLongConstantConversionPossible,
6689 Expression::ImplicitIntConstantConversionPossible): New functions
6690 that tell whether is it possible to apply an implicit constant

6704 ones that the spec expects (as we are just stringizing the
6707 * expression.cs (Unary::ResolveOperator): Fix bug: Use
6708 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
6709 previous usage did only work for our methods.
6710 (Expression::ConvertImplicit): Handle decimal implicit numeric
6711 conversions as well.
6712 (Expression::InternalTypeConstructor): Used to invoke constructors
6713 on internal types for default promotions.
6715 (Unary::Emit): Implement special handling for the pre/post
6716 increment/decrement for overloaded operators, as they need to have
6717 the same semantics as the other operators.
6719 (Binary::ResolveOperator): ditto.

6721 (UserImplicitCast::Resolve): ditto.
6723 2001-09-26 Ravi Pratap <ravi@ximian.com>
6725 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded

6740 expressions that can appear in statements, so that we can provide
6741 an alternate path to generate expression that do not leave a value
6744 (Expression::Emit, and all the derivatives): We no longer return
6745 whether a value is left on the stack or not. Every expression
6746 after being emitted leaves a single value on the stack.

6776 * assign.cs: track location.
6777 (Resolve): Use implicit conversions on assignment.

6820 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
6821 Also take an additional TypeContainer argument.
6823 * All over : Pass in TypeContainer as argument to OverloadResolve.
6825 * typemanager.cs (CSharpName): Update to check for the string type and return

6842 * typemanager.cs: declare and load enum_type, delegate_type and
6845 * expression.cs (Expression::Emit): Now emit returns a value that
6846 tells whether a value is left on the stack or not. This strategy
6847 might be reveted tomorrow with a mechanism that would address
6848 multiple assignments.
6849 (Expression::report118): Utility routine to report mismatches on
6852 (Unary::Report23): Report impossible type/operator combination

6906 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
6907 Use a basename for those routines because .NET does not like paths

6927 (IntLiteral): export the `Value' of the intliteral.

6945 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
6946 operators are found instead of making noise ;-)
6947 (Unary::ResolveOperator): New method to do precisely the same thing which
6948 Binary::ResolveOperator does for Binary expressions.
6949 (Unary.method, .Arguments): Add.
6950 (Unary::OperName): Implement.
6951 (Unary::ForceConversion): Copy and Paste !
6953 * class.cs (Operator::Define): Fix a small bug for the case when we have
6956 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
6957 for the inbuilt operators. Only overloading works for now ;-)
6959 2001-09-18 Miguel de Icaza <miguel@ximian.com>
6961 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
6962 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

6975 (FieldExpr::Emit): Implement.
6977 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
6978 the last instruction contains a return opcode to avoid generating
6979 the last `ret' instruction (this generates correct code, and it is
6980 nice to pass the peverify output).
6982 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
6983 initializer for static and instance variables.
6984 (Constructor::Emit): Allow initializer to be null in the case of
6985 static constructors. Only emit initializer for instance
6988 (TypeContainer::FindMembers): Return a null array if there are no

6998 * driver.cs: Stop compilation if there are parse errors.
7000 * cs-parser.jay (constructor_declaration): Provide default base

7003 initializers if none was specified.
7004 Catch the fact that constructors should not have parameters.
7006 * class.cs: Do not emit parent class initializers for static
7007 constructors, that should be flagged as an error.
7009 2001-09-18 Ravi Pratap <ravi@ximian.com>
7011 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
7012 Move back code into TypeContainer::Populate.

7041 (Expression::MemberLookup): Provide a version that allows to
7042 specify the MemberTypes and BindingFlags.
7044 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
7045 so it was not fetching variable information from outer blocks.
7047 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
7048 Beforefieldinit as it was buggy.
7050 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
7053 * class.cs (Constructor::Emit): Only emit if block is not null.
7054 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
7055 deal with this by semantically definining it as if the user had
7058 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
7059 constructors as we now "emit" them at a higher level.

7062 default constructors if none was provided.
7064 (ConstructorInitializer): Add methods Resolve and Emit.
7066 * expression.cs: Cast to ConstructorInfo instead of MethodInfo

7086 and Unary::Operator.
7088 * cs-parser.jay (operator_declaration, CheckBinaryOperator, CheckUnaryOperator): Update

7092 we have overloaded operators.
7093 (Binary::ResolveOperator): Implement the part which does the operator overload
7096 * class.cs (Operator::Emit): Implement.
7097 (TypeContainer::Emit): Emit the operators we have too.
7099 * expression.cs (Binary::Emit): Update to emit the appropriate code for
7100 the case when we have a user-defined operator.

7134 2001-09-14 Miguel de Icaza <miguel@ximian.com>
7136 * class.cs (TypeContainer::FindMembers): Add support for

7139 of a Constructor and a Method.

7143 Load System assembly as well as part of the standard library.
7145 * report.cs: Allow throwing exceptions on errors for debugging.
7147 * modifiers.cs: Do not use `parent', instead use the real type
7148 container to evaluate permission settings.
7150 * class.cs: Put Ravi's patch back in. He is right, and we will
7151 have to cope with the
7153 2001-09-14 Ravi Pratap <ravi@ximian.com>
7155 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

7160 * driver.cs: Added --parse option that only parses its input files
7163 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
7164 incorrect. IsTopLevel is not used to tell whether an object is
7165 root_types or not (that can be achieved by testing this ==
7166 root_types). But to see if this is a top-level *class* (not
7167 necessarly our "toplevel" container).
7169 2001-09-14 Ravi Pratap <ravi@ximian.com>
7171 * enum.cs (Enum::Define): Modify to call the Lookup method on the
7172 parent instead of a direct call to GetType.
7174 2001-09-14 Ravi Pratap <ravi@ximian.com>
7176 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
7177 Modifiers.TypeAttr. This should just be a call to that method.
7179 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
7180 object so that we can determine if we are top-level or not.
7182 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
7185 * enum.cs (Enum::Define): Ditto.
7187 * modifiers.cs (FieldAttr): Re-write.
7189 * class.cs (TypeContainer::IsTopLevel): Change accessibility to public.
7190 (TypeContainer::HaveStaticConstructor): New property to provide access
7191 to precisely that info.
7193 * modifiers.cs (MethodAttr): Re-write.
7194 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
7196 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
7197 of top-level types as claimed.
7199 2001-09-13 Miguel de Icaza <miguel@ximian.com>
7201 * expression.cs (MemberLookup): Fruitless attempt to lookup
7202 constructors. Maybe I need to emit default constructors? That
7203 might be it (currently .NET emits this for me automatically).
7204 (Invocation::OverloadResolve): Cope with Arguments == null.
7205 (Invocation::EmitArguments): new function, shared by the new
7207 (Invocation::Emit): Handle static and instance methods. Emit
7208 proper call instruction for virtual or non-virtual invocations.

7219 SimpleLookup): Auxiliary routines to help parse a qualifier
7222 Update qualifier_identifier rule.
7224 * codegen.cs: Removed debugging messages.
7226 * class.cs: Make this a global thing, this acts just as a "key" to
7227 objects that we might have around.
7229 (Populate): Only initialize method_builders_to_methods once.
7231 * expression.cs (PropertyExpr): Initialize type from the
7234 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
7235 Resolve pattern. Attempt to implicitly convert value to boolean.
7238 * expression.cs: Set the type for the int32/int32 argument case.
7239 (Binary::ResolveOperator): Set the return type to boolean for
7240 comparission operators
7242 * typemanager.cs: Remove debugging print code.

7259 on methods because System.Reflection bit us again.
7261 * support.cs: New file, contains an interface ParameterData and
7262 two implementations: ReflectionParameters and InternalParameters

7579 will is used during the tree rewriting as we resolve them during

7706 * class.cs (Property): Revamp to use the convention of making fields readonly.

7755 and re-write the code in the actions to extract the specific and
7756 general catch clauses by being a little smart ;-)
7758 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
7759 Hooray, try and catch statements parse fine !

7763 * statement.cs (Block::GetVariableType): Fix logic to extract the type
7764 string from the hashtable of variables.

7817 instead of ignoring the rank_specifiers.
7818 (expression_list): Implement to collect the expressions

7822 (array_initializer): Make it a list of variable_initializers
7823 (opt_array_initializer): Modify accordingly.

7845 types after we have populated the type manager with the user

7850 on Expression Classification. Now all expressions have a method
7851 `Resolve' and a method `Emit'.

7854 generation from working. Also add some temporary debugging
7857 2001-08-24 Miguel de Icaza <miguel@ximian.com>
7859 * codegen.cs: Lots of code generation pieces. This is only the
7860 beginning, will continue tomorrow with more touches of polish. We
7861 handle the fundamentals of if, while, do, for, return. Others are
7862 trickier and I need to start working on invocations soon.
7864 * gen-treedump.cs: Bug fix, use s.Increment here instead of
7867 * codegen.cs (EmitContext): New struct, used during code
7868 emission to keep a context. Most of the code generation will be
7871 * cs-parser.jay: Add embedded blocks to the list of statements of
7872 this block. So code generation proceeds in a top down fashion.
7874 2001-08-23 Miguel de Icaza <miguel@ximian.com>
7876 * statement.cs: Add support for multiple child blocks.
7878 2001-08-22 Miguel de Icaza <miguel@ximian.com>
7880 * codegen.cs (EmitCode): New function, will emit the code for a
7881 Block of code given a TypeContainer and its ILGenerator.
7883 * statement.cs (Block): Standard public readonly optimization.
7884 (Block::Block constructors): Link children.
7885 (Block::Child): Child Linker.
7886 (Block::EmitVariables): Emits IL variable declarations.
7888 * class.cs: Drop support for MethodGroups here, delay until
7890 (Method::): Applied the same simplification that I did before, and
7891 move from Properties to public readonly fields.
7892 (Method::ParameterTypes): Returns the parameter types for the
7893 function, and implements a cache that will be useful later when I
7894 do error checking and the semantic analysis on the methods is
7896 (Constructor::GetCallingConvention): Renamed from CallingConvetion
7897 and made a method, optional argument tells whether this is a class
7898 or a structure to apply the `has-this' bit.
7899 (Method::GetCallingConvention): Implement, returns the calling
7901 (Method::Define): Defines the type, a second pass is performed
7902 later to populate the methods.
7904 (Constructor::ParameterTypes): implement a cache similar to the
7905 one on Method::ParameterTypes, useful later when we do semantic
7908 (TypeContainer::EmitMethod): New method. Emits methods.
7910 * expression.cs: Removed MethodGroup class from here.
7912 * parameter.cs (Parameters::GetCallingConvention): new method.
7914 2001-08-21 Miguel de Icaza <miguel@ximian.com>
7916 * class.cs (TypeContainer::Populate): Drop RootContext from the
7919 (Constructor::CallingConvention): Returns the calling convention.
7920 (Constructor::ParameterTypes): Returns the constructor parameter
7923 (TypeContainer::AddConstructor): Keep track of default constructor
7924 and the default static constructor.
7926 (Constructor::) Another class that starts using `public readonly'
7927 instead of properties.
7929 (Constructor::IsDefault): Whether this is a default constructor.
7931 (Field::) use readonly public fields instead of properties also.
7933 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
7934 track of static constructors; If none is used, turn on
7935 BeforeFieldInit in the TypeAttributes.
7937 * cs-parser.jay (opt_argument_list): now the return can be null
7938 for the cases where there are no arguments.
7940 (constructor_declarator): If there is no implicit `base' or
7941 `this', then invoke the default parent constructor.
7943 * modifiers.cs (MethodAttr): New static function maps a set of
7944 modifiers flags into a MethodAttributes enum
7945 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
7946 MethodAttr, TypeAttr to represent the various mappings where the
7948 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
7950 2001-08-19 Miguel de Icaza <miguel@ximian.com>
7952 * parameter.cs (GetParameterInfo): Fix bug where there would be no
7955 * interface.cs (PopulateIndexer): Implemented the code generator
7956 for interface indexers.
7958 2001-08-17 Miguel de Icaza <miguel@ximian.com>
7960 * interface.cs (InterfaceMemberBase): Now we track the new status
7963 (PopulateProperty): Implement property population. Woohoo! Got
7964 Methods and Properties going today.
7966 Removed all the properties for interfaces, and replaced them with
7967 `public readonly' fields.
7969 2001-08-16 Miguel de Icaza <miguel@ximian.com>
7971 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
7972 initialize their hashtables/arraylists only when they are needed
7973 instead of doing this always.
7975 * parameter.cs: Handle refs and out parameters.
7977 * cs-parser.jay: Use an ArrayList to construct the arguments
7978 instead of the ParameterCollection, and then cast that to a
7981 * parameter.cs: Drop the use of ParameterCollection and use
7982 instead arrays of Parameters.
7984 (GetParameterInfo): Use the Type, not the Name when resolving
7987 2001-08-13 Miguel de Icaza <miguel@ximian.com>
7989 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
7990 and instead use public readonly fields.
7992 * class.cs: Put back walking code for type containers.
7994 2001-08-11 Miguel de Icaza <miguel@ximian.com>
7996 * class.cs (MakeConstant): Code to define constants.
7998 * rootcontext.cs (LookupType): New function. Used to locate types
8001 2001-08-08 Miguel de Icaza <miguel@ximian.com>
8003 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
8004 this System.Reflection code is. Kudos to Microsoft
8006 * typemanager.cs: Implement a type cache and avoid loading all
8007 types at boot time. Wrap in LookupType the internals. This made
8008 the compiler so much faster. Wow. I rule!
8010 * driver.cs: Make sure we always load mscorlib first (for
8011 debugging purposes, nothing really important).
8013 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
8014 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
8016 * rootcontext.cs: Lookup types on their namespace; Lookup types
8017 on namespaces that have been imported using the `using' keyword.
8019 * class.cs (TypeContainer::TypeAttr): Virtualize.
8020 (Class::TypeAttr): Return attributes suitable for this bad boy.
8021 (Struct::TypeAttr): ditto.
8022 Handle nested classes.
8023 (TypeContainer::) Remove all the type visiting code, it is now
8024 replaced with the rootcontext.cs code
8026 * rootcontext.cs (GetClassBases): Added support for structs.
8028 2001-08-06 Miguel de Icaza <miguel@ximian.com>
8030 * interface.cs, statement.cs, class.cs, parameter.cs,
8031 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
8032 Drop use of TypeRefs, and use strings instead.
8034 2001-08-04 Miguel de Icaza <miguel@ximian.com>
8038 * class.cs (Struct::Struct): set the SEALED flags after
8039 checking the modifiers.
8040 (TypeContainer::TypeAttr): new property, returns the
8041 TypeAttributes for a class.
8043 * cs-parser.jay (type_list): Oops, list production was creating a
8044 new list of base types.
8046 * rootcontext.cs (StdLib): New property.
8047 (GetInterfaceTypeByName): returns an interface by type name, and
8048 encapsulates error handling here.
8049 (GetInterfaces): simplified.
8050 (ResolveTree): Encapsulated all the tree resolution here.
8051 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
8054 * driver.cs: Add support for --nostdlib, to avoid loading the
8056 (Main): Do not put tree resolution here.
8058 * rootcontext.cs: Beginning of the class resolution.
8060 2001-08-03 Miguel de Icaza <miguel@ximian.com>
8062 * rootcontext.cs: Provide better error reporting.
8064 * cs-parser.jay (interface_base): set our $$ to be interfaces.
8066 * rootcontext.cs (CreateInterface): Handle the case where there
8067 are no parent interfaces.
8069 (CloseTypes): Routine to flush types at the end.
8070 (CreateInterface): Track types.
8071 (GetInterfaces): Returns an array of Types from the list of
8074 * typemanager.c (AddUserType): Mechanism to track user types (puts
8075 the type on the global type hash, and allows us to close it at the
8078 2001-08-02 Miguel de Icaza <miguel@ximian.com>
8080 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
8081 RecordInterface instead.
8083 * cs-parser.jay: Updated to reflect changes above.
8085 * decl.cs (Definition): Keep track of the TypeBuilder type that
8086 represents this type here. Not sure we will use it in the long
8087 run, but wont hurt for now.
8089 * driver.cs: Smaller changes to accomodate the new code.
8091 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
8094 * rootcontext.cs (CreateInterface): New method, used to create
8095 the System.TypeBuilder type for interfaces.
8096 (ResolveInterfaces): new entry point to resolve the interface
8098 (CodeGen): Property, used to keep track of the code generator.
8100 2001-07-26 Miguel de Icaza <miguel@ximian.com>
8102 * cs-parser.jay: Add a second production for delegate_declaration
8105 (enum_body): Put an opt_comma here instead of putting it on
8106 enum_body or enum_member_declarations so we can handle trailing
8107 commas on enumeration members. Gets rid of a shift/reduce.
8109 (type_list): Need a COMMA in the middle.
8111 (indexer_declaration): Tell tokenizer to recognize get/set
8113 * Remove old targets.
8115 * Re-add the parser target.
8117 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8119 * cs-parser.jay: Add precendence rules for a number of operators
8120 ot reduce the number of shift/reduce conflicts in the grammar.
8122 2001-07-17 Miguel de Icaza <miguel@ximian.com>
8124 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
8127 Get rid of old crufty code.
8129 * rootcontext.cs: Use this to keep track of the parsed
8130 representation and the defined types available to the program.
8132 * gen-treedump.cs: adjust for new convention.
8134 * type.cs: Split out the type manager, and the assembly builder
8137 * typemanager.cs: the type manager will live here now.
8139 * cil-codegen.cs: And the code generator here.
8141 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
8143 * makefile: Fixed up for easy making.
8145 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8147 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
8150 (unary_expression): Expand pre_increment_expression and
8151 post_decrement_expression to reduce a shift/reduce.
8153 2001-07-11 Simon Cozens
8155 * cs-tokenizer.cs: Hex numbers should begin with a 0.
8157 Improve allow_keyword_as_indent name.
8159 2001-06-19 Miguel de Icaza <miguel@ximian.com>
8161 * Adjustments for Beta2.
8163 2001-06-13 Miguel de Icaza <miguel@ximian.com>
8165 * decl.cs: Added `Define' abstract method.
8166 (InTransit): new property, used to catch recursive definitions.
8168 * interface.cs: Implement `Define'.
8170 * modifiers.cs: Map Modifiers.constants to
8171 System.Reflection.TypeAttribute flags.
8173 * class.cs: Keep track of types and user-defined types.
8174 (BuilderInit): New method for creating an assembly
8175 (ResolveType): New function to launch the resolution process, only
8176 used by interfaces for now.
8178 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
8179 that are inserted into the name space.
8181 2001-06-08 Miguel de Icaza <miguel@ximian.com>
8183 * ARGH. I have screwed up my tree so many times due to the use of
8184 rsync rather than using CVS. Going to fix this at once.
8186 * driver.cs: Objetify driver. Load assemblies, use assemblies to
8189 2001-06-07 Miguel de Icaza <miguel@ximian.com>
8191 * Experiment successful: Use System.Type rather that our own
8194 2001-05-25 Miguel de Icaza <miguel@ximian.com>
8196 * cs-parser.jay: Removed nsAliases from here.
8198 Use new namespaces, handle `using XXX;'
8200 * namespace.cs: Reimplemented namespace handling, use a recursive
8201 definition of the class. Now we can keep track of using clauses
8202 and catch invalid using clauses.
8204 2001-05-24 Miguel de Icaza <miguel@ximian.com>
8206 * gen-treedump.cs: Adapted for all the renaming.
8208 * expression.cs (Expression): this class now has a Type property
8209 which returns an expression Type.
8211 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
8212 `Type', as this has a different meaning now in the base
8214 2001-05-22 Miguel de Icaza <miguel@ximian.com>
8216 * interface.cs, class.cs: Removed from all the sources the
8217 references to signature computation, as we can not do method
8218 signature computation during the parsing time, as we are not
8219 trying to solve at that point distinguishing:
8223 void a (NS.Blah x) {}
8226 Which depending on the context might be valid or not, as we do not
8227 know if Blah is the same thing as NS.Blah at that point.
8229 * Redid everything so the code uses TypeRefs now instead of
8230 Types. TypeRefs are just temporary type placeholders, that need
8231 to be resolved. They initially have a pointer to a string and the
8232 current scope in which they are used. This is used later by the
8233 compiler to resolve the reference to an actual Type.
8235 * DeclSpace is no longer a CIR.Type, and neither are
8236 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
8237 are all DeclSpaces, but no Types.
8239 * type.cs (TypeRefManager): This implements the TypeRef manager,
8240 which keeps track of all the types that need to be resolved after
8241 the parsing has finished.
8243 2001-05-13 Miguel de Icaza <miguel@ximian.com>
8245 * ARGH. We are going to have to store `foreach' as a class rather
8246 than resolving it, as we need to verify error 1579 after name
8247 resolution. *OR* we could keep a flag that says `This request to
8248 IEnumerator comes from a foreach statement' which we can then use
8249 to generate the error.
8251 2001-05-10 Miguel de Icaza <miguel@ximian.com>
8253 * class.cs (TypeContainer.AddMethod): we now add methods to the
8254 MethodGroup instead of the method hashtable.
8256 * expression.cs: Add MethodGroup abstraction, which gets us one
8257 step closer to the specification in the way we handle method
8260 * cs-parser.jay (primary_expression): qualified_identifier now
8261 tried to match up an identifier to a local variable reference or
8262 to a parameter reference.
8264 current_local_parameters is now a parser global variable that
8265 points to the current parameters for the block, used during name
8268 (property_declaration): Now creates an implicit `value' argument to
8271 2001-05-09 Miguel de Icaza <miguel@ximian.com>
8273 * parameter.cs: Do not use `param' arguments as part of the
8274 signature, per the spec.
8276 2001-05-08 Miguel de Icaza <miguel@ximian.com>
8278 * decl.cs: Base class for classes, structs and interfaces. This
8279 is the "Declaration Space"
8281 * cs-parser.jay: Use CheckDef for checking declaration errors
8282 instead of having one on each function.
8284 * class.cs: Factor out some code for handling error handling in
8285 accordance to the "Declarations" section in the "Basic Concepts"
8286 chapter in the ECMA C# spec.
8288 * interface.cs: Make all interface member classes derive from
8289 InterfaceMemberBase.
8291 2001-05-07 Miguel de Icaza <miguel@ximian.com>
8293 * Many things: all interfaces are parsed and generated in
8294 gen-treedump. Support for member variables, constructors,
8295 destructors, properties, constants is there.
8297 Beginning of the IL backend, but very little done, just there for
8300 2001-04-29 Miguel de Icaza <miguel@ximian.com>
8302 * cs-parser.jay: Fix labeled statement.
8304 * cs-tokenizer.cs (escape): Escape " and ' always.
8305 ref_line, ref_name: keep track of the line/filename as instructed
8306 by #line by the compiler.
8309 2001-04-27 Miguel de Icaza <miguel@ximian.com>
8311 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
8312 to match the values in System.CodeDOM.
8314 Divid renamed to Divide.
8316 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
8318 (Statements.set): remove.
8320 * System.CodeDOM/CodeCatchClause.cs: always have a valid
8323 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
8324 falseStatements always have valid values.
8326 * cs-parser.jay: Use System.CodeDOM now.
