224 2002-07-27 Martin Baulig <martin@gnome.org>
226 * expression.cs (Invocation.EmitArguments): When calling a varargs
227 function with only its fixed arguments, we need to pass an empty
230 2002-07-27 Martin Baulig <martin@gnome.org>
232 Mono 0.13 has been released.
234 2002-07-25 Miguel de Icaza <miguel@ximian.com>
236 * driver.cs: Rename --resource to --linkres, because that is what
237 we do currently, we dont support --resource yet.
239 * cs-tokenizer.cs: Fix test for reporting endif mismatches.
241 2002-07-25 Martin Baulig <martin@gnome.org>
243 * class.cs (MethodData): New public class. This is a `method builder'
244 class for a method or one accessor of a Property/Indexer/Event.

254 accessor/method to MethodData.
255 (Method): Create a new MethodData and call Define() and Emit() on it.
256 (Property, Indexer, Event): Create a new MethodData objects for each
257 accessor and call Define() and Emit() on them.
259 2002-07-25 Martin Baulig <martin@gnome.org>
261 Made MethodCore derive from MemberBase to reuse the code from there.
262 MemberBase now also checks for attributes.
264 * class.cs (MethodCore): Derive from MemberBase, not MemberCore.
265 (MemberBase.GetMethodFlags): Moved here from class Method and marked
267 (MemberBase.DefineAccessor): Renamed to DefineMethod(), added

279 initialize ParameterTypes and ParameterInfo.
280 (Method.GetReturnType): We can now simply return the MemberType.
281 (Method.GetMethodFlags): Override the MemberBase version and add
282 the conditional flags.
283 (Method.CheckBase): Moved some code from Define() here, call
284 DoDefineParameters() here.

286 here to avoid some larger code duplication.
287 (Property.Emit, Indexer.Emit): Call CheckAbstractAndExternal() to
288 ensure that abstract and external accessors don't declare a body.
290 * attribute.cs (Attribute.GetValidPieces): Make this actually work:
291 `System.Attribute.GetCustomAttributes (attr.Type)' does a recursive
292 lookup in the attribute's parent classes, so we need to abort as soon
293 as we found the first match.
294 (Attribute.Obsolete_GetObsoleteMessage): Return the empty string if
295 the attribute has no arguments.
297 * typemanager.cs (TypeManager.AddMethod): Now takes a MemberBase instead
300 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
302 * cs-parser.jay: reverted previous patch.
304 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
306 * cs-parser.jay: fixed bug #22119.
308 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
310 * attribute.cs: fixed compilation. The error was:
311 "attribute.cs(571,17): error CS0177: The out parameter 'is_error' must
312 be assigned to before control leaves the current method."
313 [FIXME: Filed as bug #28186: MCS must report this error.]
315 2002-07-25 Martin Baulig <martin@gnome.org>
317 * attribute.cs (Attribute.Conditional_GetConditionName): New static
318 method to pull the condition name ouf of a Conditional attribute.
319 (Attribute.Obsolete_GetObsoleteMessage): New static method to pull
320 the obsolete message and error flag out of an Obsolete attribute.
322 * class.cs (Method.GetMethodFlags): New public method to get the
323 TypeManager.MethodFlags for this method.
324 (Method.ApplyConditionalAttribute, Method.ApplyObsoleteAttribute): New
326 (Method.Define): Get and apply the Obsolete and Conditional attributes;
327 if we're overriding a virtual function, set the new private variable
328 `parent_method'; call the new TypeManager.AddMethod().
330 * typemanager.cs (TypeManager.AddMethod): New static method. Stores
331 the MethodBuilder and the Method in a PtrHashtable.
332 (TypeManager.builder_to_method): Added for this purpose.
333 (TypeManager.MethodFlags): Added IsObsoleteError.
334 (TypeManager.GetMethodFlags): Added `Location loc' argument. Lookup
335 Obsolete and Conditional arguments in MethodBuilders. If we discover
336 an Obsolete attribute, emit an appropriate warning 618 / error 619 with
337 the message from the attribute.
339 2002-07-24 Martin Baulig <martin@gnome.org>
341 * cs-tokenizer.cs: Eat up trailing whitespaces and one-line comments in
342 preprocessor directives, ensure that the argument to #define/#undef is
343 exactly one identifier and that it's actually an identifier.
345 Some weeks ago I did a `#define DEBUG 1' myself and wondered why this
348 2002-07-24 Martin Baulig <martin@gnome.org>
350 * statement.cs (Foreach.ForeachHelperMethods): Added `Type element_type',
351 initialize it to TypeManager.object_type in the constructor.
352 (Foreach.GetEnumeratorFilter): Set `hm.element_type' to the return type
353 of the `hm.get_current' method if we're using the collection pattern.
354 (Foreach.EmitCollectionForeach): Use `hm.element_type' as the source type
355 for the explicit conversion to make it work when we're using the collection
356 pattern and the `Current' property has a different return type than `object'.
359 2002-07-24 Martin Baulig <martin@gnome.org>
361 * delegate.cs (Delegate.VerifyMethod): Simply return null if the method
362 does not match, but don't report any errors. This method is called in
363 order for all methods in a MethodGroupExpr until a matching method is
364 found, so we don't want to bail out if the first method doesn't match.
365 (NewDelegate.DoResolve): If none of the methods in the MethodGroupExpr
366 matches, report the 123. Fixes #28070.
368 2002-07-24 Martin Baulig <martin@gnome.org>
370 * expression.cs (ArrayAccess.EmitStoreOpcode): Moved the
371 TypeManager.TypeToCoreType() to the top of the method so the
372 following equality checks will work. Fixes #28107.
374 2002-07-24 Martin Baulig <martin@gnome.org>
376 * cfold.cs (ConstantFold.DoConstantNumericPromotions): "If either
377 operand is of type uint, and the other operand is of type sbyte,
378 short or int, the operands are converted to type long." -
379 Actually do what this comment already told us. Fixes bug #28106,
382 2002-07-24 Martin Baulig <martin@gnome.org>
384 * class.cs (MethodBase): New abstract class. This is now a base
385 class for Property, Indexer and Event to avoid some code duplication
386 in their Define() and DefineMethods() methods.
387 (MethodBase.DoDefine, MethodBase.DefineAccessor): Provide virtual
388 generic methods for Define() and DefineMethods().
389 (FieldBase): Derive from MemberBase, not MemberCore.
390 (Property): Derive from MemberBase, not MemberCore.
391 (Property.DefineMethod): Moved all the code from this method to the
392 new MethodBase.DefineAccessor(), just call it with appropriate
394 (Property.Define): Call the new Property.DoDefine(), this does some
395 sanity checks and we don't need to duplicate the code everywhere.
396 (Event): Derive from MemberBase, not MemberCore.
397 (Event.Define): Use the new MethodBase.DefineAccessor() to define the
398 accessors, this will also make them work with interface events.
399 (Indexer): Derive from MemberBase, not MemberCore.
400 (Indexer.DefineMethod): Removed, call MethodBase.DefineAccessor() insstead.
401 (Indexer.Define): Use the new MethodBase functions.

404 argument to the constructor.
405 (Interface.FindMembers): Added support for interface events.
406 (Interface.PopluateEvent): Implemented.
408 Added test-149.cs for this. This also fixes bugs #26067 and #24256.
410 2002-07-22 Miguel de Icaza <miguel@ximian.com>
412 * class.cs (TypeContainer.AddMethod): Adding methods do not use IsValid,
413 but this is required to check for a method name being the same as
414 the containing class.
418 2002-07-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
420 * interface.cs: initialize variable.
422 2002-07-23 Martin Baulig <martin@gnome.org>
424 Implemented the IndexerName attribute in interfaces.
426 * class.cs (TypeContainer.DefineIndexers): Don't set the indexer
427 name if this is an explicit interface implementation.
428 (Indexer.InterfaceIndexerName): New public variable. If we're
429 implementing an interface indexer, this is the IndexerName in that
430 interface. Otherwise, it's the IndexerName.
431 (Indexer.DefineMethod): If we're implementing interface indexer,
432 set InterfaceIndexerName. Use the new Pending.IsInterfaceIndexer
433 and Pending.ImplementIndexer methods.
434 (Indexer.Define): Also define the PropertyBuilder if we're
435 implementing an interface indexer and this is neither an explicit
436 interface implementation nor do the IndexerName match the one in
439 * pending.cs (TypeAndMethods): Added `MethodInfo [] need_proxy'.
440 If a method is defined here, then we always need to create a proxy
441 for it. This is used when implementing interface indexers.
442 (Pending.IsInterfaceIndexer): New public method.
443 (Pending.ImplementIndexer): New public method.
444 (Pending.InterfaceMethod): Added `MethodInfo need_proxy' argument.
445 This is used when implementing interface indexers to define a proxy
447 (Pending.VerifyPendingMethods): Look in the `need_proxy' array and
448 define a proxy if necessary.
450 * interface.cs (Interface.IndexerName): New public variable.
451 (Interface.PopulateIndexer): Set the IndexerName.
452 (Interface.DefineIndexers): New private method. Populate all the
453 indexers and make sure their IndexerNames match.
455 * typemanager.cs (IndexerPropertyName): Added support for interface
458 2002-07-22 Martin Baulig <martin@gnome.org>
460 * codegen.cs (EmitContext.HasReturnLabel): New public variable.
461 (EmitContext.EmitTopBlock): Always mark the ReturnLabel and emit a
462 ret if HasReturnLabel.
463 (EmitContext.TryCatchLevel, LoopBeginTryCatchLevel): New public
466 * statement.cs (Do.Emit, While.Emit, For.Emit, Foreach.Emit): Save
467 and set the ec.LoopBeginTryCatchLevel.
468 (Try.Emit): Increment the ec.TryCatchLevel while emitting the block.
469 (Continue.Emit): If the ec.LoopBeginTryCatchLevel is smaller than
470 the current ec.TryCatchLevel, the branch goes out of an exception
471 block. In this case, we need to use Leave and not Br.
473 2002-07-22 Martin Baulig <martin@gnome.org>
475 * statement.cs (Try.Emit): Emit an explicit ret after the end of the
476 block unless the block does not always return or it is contained in
477 another try { ... } catch { ... } block. Fixes bug #26506.
478 Added verify-1.cs to the test suite.
480 2002-07-22 Martin Baulig <martin@gnome.org>
482 * statement.cs (Switch.TableSwitchEmit): If we don't have a default,
483 then we do not always return. Fixes bug #24985.
485 2002-07-22 Martin Baulig <martin@gnome.org>
487 * expression.cs (Invocation.OverloadedResolve): Do the BetterFunction()
488 lookup on a per-class level; ie. walk up the class hierarchy until we
489 found at least one applicable method, then choose the best among them.
490 Fixes bug #24463 and test-29.cs.
492 2002-07-22 Martin Baulig <martin@gnome.org>
494 * typemanager.cs (TypeManager.ArrayContainsMethod): Don't check the
495 return types of the methods. The return type is not part of the
496 signature and we must not check it to make the `new' modifier work.
497 Fixes bug #27999, also added test-147.cs.
498 (TypeManager.TypeToCoreType): Added TypeManager.type_type.
500 * expression.cs (Invocation.DoResolve): Call TypeManager.TypeToCoreType()
501 on the method's return type.
503 2002-07-21 Martin Baulig <martin@gnome.org>
505 * assign.cs: Make this work if the rightmost source is a constant and
506 we need to do an implicit type conversion. Also adding a few more tests
507 to test-38.cs which should have caught this.
509 * makefile.gnu: Disable debugging, there's already the mcs-mono2.exe
510 target in the makefile for this. The makefile.gnu is primarily intended
511 for end-users who don't want to debug the compiler.
513 2002-07-21 Martin Baulig <martin@gnome.org>
515 * assign.cs: Improved the Assign class so it can now handle embedded
516 assignments (X = Y = Z = something). As a side-effect this'll now also
517 consume less local variables. test-38.cs now passes with MCS, added
518 a few new test cases to that test.
520 2002-07-20 Martin Baulig <martin@gnome.org>
522 * expression.cs (Binary.EmitBranchable): Emit correct unsigned branch
523 instructions. Fixes bug #27977, also added test-146.cs.
525 2002-07-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
527 * cs-tokenizer.cs: fixed getHex ().
529 2002-07-19 Martin Baulig <martin@gnome.org>
531 * expression.cs (Invocation.EmitParams): Use TypeManager.LookupType(),
532 not Type.GetType() to lookup the array type. This is needed when
533 we're constructing an array of a user-defined type.
534 (ArrayAccess.EmitDynamicInitializers): Only emit the Ldelema for
535 single-dimensional arrays, but also for single-dimensial arrays of
538 2002-07-19 Martin Baulig <martin@gnome.org>
540 * expression.cs (New.DoEmit): Create a new LocalTemporary each time
541 this function is called, it's not allowed to share LocalBuilders
544 2002-07-19 Martin Baulig <martin@gnome.org>
546 * expression.cs (Argument.Resolve): Report an error 118 when trying
547 to pass a type as argument.
549 2002-07-18 Martin Baulig <martin@gnome.org>
551 * ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
552 Conv_R_Un for the signed `long' type.
554 2002-07-15 Miguel de Icaza <miguel@ximian.com>
556 * expression.cs (MemberAccess.DoResolve): Do not reuse the field
557 `expr' for the temporary result, as that will fail if we do
558 multiple resolves on the same expression.
560 2002-07-05 Miguel de Icaza <miguel@ximian.com>
562 * ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
563 ec.TypeContainer for looking up aliases.
565 * class.cs (TypeContainer): Remove LookupAlias from here.
567 * decl.cs (DeclSpace); Move here.
569 2002-07-01 Miguel de Icaza <miguel@ximian.com>
571 * class.cs (FindMembers): Only call filter if the constructor
574 Also handle delegates in `NestedTypes' now. Now we will perform
575 type lookups using the standard resolution process. This also
578 * decl.cs (DeclSpace.ResolveType): New type resolution routine.
579 This uses Expressions (the limited kind that can be parsed by the
580 tree) instead of strings.
582 * expression.cs (ComposedCast.ToString): Implement, used to flag
583 errors since now we have to render expressions.
585 (ArrayCreation): Kill FormElementType. Use ComposedCasts in
588 * ecore.cs (SimpleName.ToString): ditto.
590 * cs-parser.jay: Instead of using strings to assemble types, use
591 Expressions to assemble the type (using SimpleName, ComposedCast,
592 MemberAccess). This should fix the type lookups in declarations,
593 because we were using a different code path for this.
595 * statement.cs (Block.Resolve): Continue processing statements
596 even when there is an error.
598 2002-07-17 Miguel de Icaza <miguel@ximian.com>
600 * class.cs (Event.Define): Also remove the `remove' method from
601 the list of pending items.
603 * expression.cs (ParameterReference): Use ldarg.N (0..3) to
604 generate more compact code.
606 2002-07-17 Martin Baulig <martin@gnome.org>
608 * const.cs (Const.LookupConstantValue): Add support for constant
609 `unchecked' and `checked' expressions.
610 Also adding test case test-140.cs for this.
612 2002-07-17 Martin Baulig <martin@gnome.org>
614 * statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
615 check whether mi.ReturnType implements the IEnumerator interface; the
616 `==' and the IsAssignableFrom() will fail in this situation.
618 2002-07-16 Ravi Pratap <ravi@ximian.com>
620 * ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix
623 2002-07-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
625 * expression.cs: fixed bug #27811.
627 2002-07-14 Miguel de Icaza <miguel@ximian.com>
629 * expression.cs (ParameterReference.AddressOf): Patch from Paolo
630 Molaro: when we are a ref, the value already contains a pointer
631 value, do not take the address of it.
633 2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
634 * removed mb-parser.jay and mb-tokenizer.cs
636 Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
638 * expression.cs: check against the building corlib void type.
640 Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
642 * ecore.cs: fix for valuetype static readonly fields: when
643 initializing them, we need their address, not the address of a copy.
645 Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
647 * typemanager.cs: register also enum_type in corlib.
649 Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
651 * class.cs: allow calling this (but not base) initializers in structs.
653 Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
655 * ecore.cs: make sure we compare against the building base types
658 Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
660 * typemanager.cs: fix TypeToCoreType() to handle void and object
661 (corlib gets no more typerefs after this change).
663 2002-07-12 Miguel de Icaza <miguel@ximian.com>
665 * expression.cs (ArrayCreation.EmitArrayArguments): use
666 Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
668 (ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
669 Conv_Ovf_I_Un for the array arguments. Even if C# allows longs as
670 array indexes, the runtime actually forbids them.
672 * ecore.cs (ExpressionToArrayArgument): Move the conversion code
673 for array arguments here.
675 * expression.cs (EmitLoadOpcode): System.Char is a U2, use that
676 instead of the default for ValueTypes.
678 (New.DoEmit): Use IsValueType instead of
679 IsSubclassOf (value_type)
680 (New.DoResolve): ditto.
681 (Invocation.EmitCall): ditto.
683 * assign.cs (Assign): ditto.
685 * statement.cs (Unsafe): Ok, so I got the semantics wrong.
686 Statements *are* currently doing part of their resolution during
689 Expressions do always resolve during resolve, but statements are
690 only required to propagate resolution to their children.
692 2002-07-11 Miguel de Icaza <miguel@ximian.com>
694 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
696 (LoadAssembly): Do not add the dll if it is already specified
698 (MainDriver): Add the System directory to the link path at the end,
699 after all the other -L arguments.
701 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
702 wrong opcode for loading bytes and bools (ldelem.i1 instead of
703 ldelem.u1) and using the opposite for sbytes.
705 This fixes Digger, and we can finally run it.
707 * driver.cs (UnixParseOption): Move the option parsing here.
708 (CSCParseOption): Implement CSC-like parsing of options.
710 We now support both modes of operation, the old Unix way, and the
711 new CSC-like way. This should help those who wanted to make cross
714 The only thing broken is that /r:, /reference: and /lib: are not
715 implemented, because I want to make those have the same semantics
716 as the CSC compiler has, and kill once and for all the confussion
717 around this. Will be doing this tomorrow.
719 * statement.cs (Unsafe.Resolve): The state is checked during
720 resolve, not emit, so we have to set the flags for IsUnsfe here.
722 2002-07-10 Miguel de Icaza <miguel@ximian.com>
724 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
725 not catch the Error_ObjectRefRequired in SimpleName (as it is
726 possible to have a class/instance variable name that later gets
727 deambiguated), we have to check this here.
729 2002-07-10 Ravi Pratap <ravi@ximian.com>
731 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
732 make static and put into Expression.
734 (Event.Define): Register the private field of the event with the
735 TypeManager so that GetFieldFromEvent can get at it.
737 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
738 keep track of the private field associated with an event which
741 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
744 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
746 2002-07-10 Miguel de Icaza <miguel@ximian.com>
748 * expression.cs (Binary.EmitBranchable): this routine emits the
749 Binary expression in a branchable context. This basically means:
750 we need to branch somewhere, not just get the value on the stack.
752 This works together with Statement.EmitBoolExpression.
754 * statement.cs (Statement.EmitBoolExpression): Use
757 2002-07-09 Miguel de Icaza <miguel@ximian.com>
759 * statement.cs (For): Reduce the number of jumps in loops.
761 (For): Implement loop inversion for the For statement.
763 (Break): We can be breaking out of a Try/Catch controlled section
764 (foreach might have an implicit try/catch clause), so we need to
765 use Leave instead of Br.
767 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
768 now). If the instace expression supports IMemoryLocation, we use
769 the AddressOf method from the IMemoryLocation to extract the
770 address instead of emitting the instance.
772 This showed up with `This', as we were emitting the instance
773 always (Emit) instead of the Address of This. Particularly
774 interesting when This is a value type, as we dont want the Emit
775 effect (which was to load the object).
777 2002-07-08 Miguel de Icaza <miguel@ximian.com>
779 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
781 * statement.cs (Checked): Set the CheckedState during the resolve
782 process too, as the ConvCast operations track the checked state on
783 the resolve process, and not emit.
785 * cs-parser.jay (namespace_member_declaration): Flag that we have
786 found a declaration when we do. This is used to flag error 1529
788 * driver.cs: Report ok when we display the help only.
790 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
792 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
794 2002-07-04 Miguel de Icaza <miguel@ximian.com>
796 * cs-tokenizer.cs (define): We also have to track locally the
797 defines. AllDefines is just used for the Conditional Attribute,
798 but we also need the local defines for the current source code.
800 2002-07-03 Miguel de Icaza <miguel@ximian.com>
802 * statement.cs (While, For, Do): These loops can exit through a
803 Break statement, use this information to tell whether the
804 statement is the last piece of code.
806 (Break): Flag that we break.
808 * codegen.cs (EmitContexts): New `Breaks' state variable.
810 2002-07-03 Martin Baulig <martin@gnome.org>
812 * class.cs (TypeContainer.MethodModifiersValid): Allow override
813 modifiers in method declarations in structs. Otherwise, you won't
814 be able to override things like Object.Equals().
816 2002-07-02 Miguel de Icaza <miguel@ximian.com>
818 * class.cs (Method, Property, Indexer): Do not allow the public
819 modifier to be used in explicit interface implementations.
821 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
822 override modifiers in method declarations in structs
824 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
826 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
827 integer or real overflow, report an error
829 2002-07-02 Martin Baulig <martin@gnome.org>
831 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
832 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
833 to tell the runtime about our newly created System.Object and
834 System.ValueType types.
836 2002-07-02 Miguel de Icaza <miguel@ximian.com>
838 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
839 struct instead of Ldarg/Starg.
841 2002-07-02 Martin Baulig <martin@gnome.org>
843 * expression.cs (Indirection.Indirection): Call
844 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
846 2002-07-02 Martin Baulig <martin@gnome.org>
848 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
849 ValueType, call TypeManager.TypeToCoreType() on it.
850 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
851 the OpCodes.Newarr argument.
853 2002-07-02 Martin Baulig <martin@gnome.org>
855 * expression.cs (Invocation.EmitCall): When compiling corlib,
856 replace all calls to the system's System.Array type to calls to
857 the newly created one.
859 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
860 System.Array methods.
861 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
862 from the system's System.Array type which must be replaced.
864 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
866 * typemanager.cs: load unverifiable_code_ctor so we can build
867 corlib using the correct type. Avoid using GetTypeCode() with
869 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
870 TypeManager.object_type to allow building corlib.
872 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
874 * ecore.cs: handle System.Enum separately in LoadFromPtr().
876 2002-07-01 Martin Baulig <martin@gnome.org>
878 * class.cs: Make the last change actually work, we need to check
879 whether `ifaces != null' to avoid a crash.
881 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
883 * class.cs: when we build structs without fields that implement
884 interfaces, we need to add the interfaces separately, since there is
885 no API to both set the size and add the interfaces at type creation
888 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
890 * expression.cs: the dimension arguments to the array constructors
891 need to be converted if they are a long.
893 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
895 * class.cs: don't emit ldarg.0 if there is no parent constructor
896 (fixes showstopper for corlib).
898 2002-06-29 Martin Baulig <martin@gnome.org>
900 MCS now compiles corlib on GNU/Linux :-)
902 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
903 ie. check for MethodImplOptions.InternalCall.
905 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
906 and TypeManager.attribute_type are null, so we must explicitly check
907 whether parent is not null to find out whether it's an attribute type.
908 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
909 and SetBuilder, not only if the property is neither abstract nor external.
910 This is necessary to set the MethodImplOptions on the accessor methods.
911 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
912 SetBuilder, see Property.Emit().
914 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
915 populate "System.Object", "System.ValueType" and "System.Attribute" since
916 they've already been populated from BootCorlib_PopulateCoreTypes().
918 2002-06-29 Martin Baulig <martin@gnome.org>
920 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
921 is the NullLiteral, we also need to make sure that target_type is not
924 2002-06-29 Martin Baulig <martin@gnome.org>
926 * rootcontext.cs (RootContext.ResolveCore): We must initialize
927 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
928 before calling BootstrapCorlib_ResolveDelegate ().
930 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
932 * statement.cs: fixed build-breaker. All tests passed ok.
934 2002-06-27 Martin Baulig <martin@gnome.org>
936 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
937 for System.Decimal when compiling corlib.
939 2002-06-27 Martin Baulig <martin@gnome.org>
941 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
942 switch blocks which contain nothing but a default clause.
944 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
946 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
948 2002-06-27 Martin Baulig <martin@gnome.org>
950 * ecore.cs (PropertyExpr.PropertyExpr): Call
951 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
953 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
954 is already a TypeBuilder.
956 2002-06-27 Martin Baulig <martin@gnome.org>
958 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
959 `target_type == TypeManager.array_type', not IsAssignableFrom() in
960 the "from an array-type to System.Array" case. This makes it work
961 when compiling corlib.
963 2002-06-27 Martin Baulig <martin@gnome.org>
965 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
966 non-static PropertyExpr, set its InstanceExpression. This makes
967 the `ICollection.Count' property work in System/Array.cs.
969 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
971 * driver.cs: Made error handling more consistent. Errors now
972 tracked by Report class, so many methods which used to return int
973 now return void. Main() now prints success/failure and
974 errors/warnings message.
976 Renamed '--probe' compiler argument to '--expect-error'. Removed
977 the magic number return values (123 and 124). Now, if the
978 expected error occurs, the compiler exits with success (exit value
979 0). If the compilation completes without seeing that particular
980 error, the compiler exits with failure (exit value 1). The
981 makefile in mcs/errors has been changed to handle the new behaviour.
983 * report.cs: Made 'expected error' number a property and renamed
984 it from 'Probe' to 'ExpectedError'.
986 * genericparser.cs: Removed error handling support, since it is
987 now all done by Report class.
989 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
990 class, so parse() no longer returns an int.
992 * namespace.cs: Use Report.Error instead of GenericParser.error
994 2002-06-22 Miguel de Icaza <miguel@ximian.com>
996 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
997 TypeContainer.AddOperator): At the front of the list put the
998 explicit implementations, so they get resolved/defined first.
1000 2002-06-21 Miguel de Icaza <miguel@ximian.com>
1002 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
1003 interface type is implemented by this TypeContainer. Used during
1004 explicit interface implementation.
1006 (Property.Define, Indexer.Define, Method.Define): Validate that
1007 the given interface in the explicit implementation is one of the
1008 base classes for the containing type.
1010 Also if we are explicitly implementing an interface, but there is
1011 no match in the pending implementation table, report an error.
1013 (Property.Define): Only define the property if we are
1014 not explicitly implementing a property from an interface. Use the
1015 correct name also for those properties (the same CSC uses,
1016 although that is really not needed).
1018 (Property.Emit): Do not emit attributes for explicitly implemented
1019 properties, as there is no TypeBuilder.
1021 (Indexer.Emit): ditto.
1023 Hiding then means that we do not really *implement* a pending
1024 implementation, which makes code fail.
1026 2002-06-22 Martin Baulig <martin@gnome.org>
1028 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
1029 the return value of Object.GetType(). [FIXME: we need to do this whenever
1030 we get a type back from the reflection library].
1032 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
1034 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
1036 2002-06-20 Miguel de Icaza <miguel@ximian.com>
1038 * attribute.cs: Return null if we can not look up the type.
1040 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
1041 the interface types found.
1043 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
1044 interface types found.
1046 * typemanager.cs (GetInterfaces): Make this routine returns alll
1047 the interfaces and work around the lame differences between
1048 System.Type and System.Reflection.Emit.TypeBuilder in the results
1049 result for GetInterfaces.
1051 (ExpandInterfaces): Given an array of interface types, expand and
1052 eliminate repeated ocurrences of an interface. This expands in
1053 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
1056 2002-06-21 Martin Baulig <martin@gnome.org>
1058 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
1061 2002-06-21 Martin Baulig <martin@gnome.org>
1063 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
1064 and called with one of the core types, return the corresponding typebuilder for
1067 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
1070 2002-06-21 Martin Baulig <martin@gnome.org>
1072 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
1073 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
1074 (Expression.ConvertReferenceExplicit): Likewise.
1076 * expression.cs (ElementAccess.DoResolve): Likewise.
1077 (ElementAccess.DoResolveLValue): Likewise.
1079 2002-06-10 Martin Baulig <martin@gnome.org>
1081 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
1082 add the "value" parameter to the parameter list.
1084 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
1087 2002-06-19 Miguel de Icaza <miguel@ximian.com>
1089 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
1090 the argument to an int, uint, long or ulong, per the spec. Also
1091 catch negative constants in array creation.
1093 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
1095 * class.cs: do not allow the same interface to appear twice in
1096 the definition list.
1098 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
1100 * ecore.cs: don't use ldlen with System.Array.
1102 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
1104 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
1106 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
1108 * modifiers.cs: produce correct field attributes for protected
1109 internal. Easy fix so miguel can work on ther harder stuff:-)
1111 2002-06-18 Miguel de Icaza <miguel@ximian.com>
1113 * pending.cs: New file. Move the code from class.cs here.
1114 Support clearning the pending flag for all methods (when not doing
1115 explicit interface implementation).
1117 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
1119 * rootcontext.cs: added a couple more types needed to bootstrap.
1121 2002-06-17 Miguel de Icaza <miguel@ximian.com>
1123 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
1124 constructor in the type, instead of any constructor in the type
1125 hierarchy. Thanks to Paolo for finding this bug (it showed up as
1126 a bug in the Mono runtime when applying the params attribute).
1128 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1129 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
1131 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
1133 * expression.cs (Unary.ResolveOperator): Use TypeManager
1134 to resolve the type.
1136 2002-06-13 Ravi Pratap <ravi@ximian.com>
1138 * cs-parser.jay (enum_member_declaration): Pass in the attributes
1141 * enum.cs (AddEnumMember): Add support to store the attributes associated
1142 with each member too.
1144 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
1145 field builders too - this takes care of the enum member case.
1147 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
1149 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
1150 address-of operator on both value types and pointers.
1152 2002-06-10 Martin Baulig <martin@gnome.org>
1154 * interface.cs (Interface.PopulateIndexer): Add the indexer's
1155 PropertyBuilder to the `property_builders' list.
1157 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
1158 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
1159 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
1160 find any indexers which are inherited from an interface.
1162 2002-06-09 Martin Baulig <martin@gnome.org>
1164 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
1165 the same type as the constant if necessary. There's also a test-130.cs
1168 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
1170 * typemanager.cs (TypeManager.ChangeType): Previously known as
1171 Enum.ChangeEnumType().
1173 2002-06-09 Martin Baulig <martin@gnome.org>
1175 * expression.cs (Cast.TryReduce): Added support for consts.
1177 2002-06-08 Ravi Pratap <ravi@ximian.com>
1179 * class.cs (Accessor): Hold attributes information so we can pass
1182 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
1183 Modify to pass in attributes attached to the methods.
1185 (add_accessor_declaration, remove_accessor_declaration): Ditto.
1187 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
1188 to handle the Accessor kind :-)
1190 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
1192 2002-06-08 Martin Baulig <martin@gnome.org>
1194 * expression.cs (Unary.TryReduceNegative): Added support for
1197 2002-06-08 Martin Baulig <martin@gnome.org>
1199 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
1200 name can't be found in the `defined_names' - the caller will do a
1201 MemberLookup in this case and thus find methods in System.Enum
1202 such as Enum.IsDefined().
1204 2002-06-08 Martin Baulig <martin@gnome.org>
1206 * enum.cs (Enum.ChangeEnumType): This is a custom version of
1207 Convert.ChangeType() which works with TypeBuilder created types.
1208 (Enum.LookupEnumValue, Enum.Define): Use it here.
1210 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
1211 `TypeBuilder.BaseType != null' check.
1212 (TypeContainer.FindMembers): Only lookup parent members if we
1213 actually have a parent.
1214 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
1215 (ConstructorInitializer.Resolve): Likewise.
1217 * interface.cs (Interface.FindMembers): Added
1218 `TypeBuilder.BaseType != null' check.
1220 * rootcontext.cs (RootContext.ResolveCore): Added
1221 "System.Runtime.CompilerServices.IndexerNameAttribute" to
1222 classes_second_stage.
1224 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
1225 debug_type and trace_type when compiling with --nostdlib.
1227 2002-06-07 Martin Baulig <martin@gnome.org>
1229 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
1230 (AddField): Set it to true when adding a non-static field.
1231 (DefineType): Use `have_nonstatic_fields' to find out whether we
1232 have non-static fields, not `Fields != null'.
1234 2002-06-02 Miguel de Icaza <miguel@ximian.com>
1236 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
1237 dereferencing a null on the static-field code path)
1239 2002-05-30 Martin Baulig <martin@gnome.org>
1241 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
1242 to take command line arguments. Use reflection to call the new
1243 custom `Initialize' function on the symbol writer and pass it the
1244 command line arguments.
1246 * driver.cs (--debug-args): New command line argument to pass command
1247 line arguments to the symbol writer.
1249 2002-05-28 Miguel de Icaza <miguel@ximian.com>
1251 * assign.cs (DoResolve): Forgot to do the implicit conversion to
1252 the target type for indexers and properties. Thanks to Joe for
1255 2002-05-27 Miguel de Icaza <miguel@ximian.com>
1257 * typemanager.cs (MethodFlags): returns the method flags
1258 (Obsolete/ShouldIgnore) that control warning emission and whether
1259 the invocation should be made, or ignored.
1261 * expression.cs (Invocation.Emit): Remove previous hack, we should
1262 not do this on matching a base type, we should do this based on an attribute
1264 Only emit calls to System.Diagnostics.Debug and
1265 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
1266 on the command line.
1268 * rootcontext.cs: Global settings for tracing and debugging.
1270 * cs-tokenizer.cs (define): New utility function to track
1271 defines. Set the global settings for TRACE and DEBUG if found.
1273 2002-05-25 Ravi Pratap <ravi@ximian.com>
1275 * interface.cs (Populate*): Pass in the TypeContainer as well as
1276 the DeclSpace as parameters so that we can create EmitContexts and
1277 then use that to apply attributes etc.
1279 (PopulateMethod, PopulateEvent, PopulateProperty)
1280 (PopulateIndexer): Apply attributes everywhere.
1282 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
1285 (ApplyAttributes): Update accordingly.
1287 We now apply interface attributes for all members too.
1289 2002-05-26 Miguel de Icaza <miguel@ximian.com>
1291 * class.cs (Indexer.Define); Correctly check if we are explicit
1292 implementation (instead of checking the Name for a ".", we
1293 directly look up if the InterfaceType was specified).
1295 Delay the creation of the PropertyBuilder.
1297 Only create the PropertyBuilder if we are not an explicit
1298 interface implementation. This means that explicit interface
1299 implementation members do not participate in regular function
1300 lookups, and hence fixes another major ambiguity problem in
1301 overload resolution (that was the visible effect).
1303 (DefineMethod): Return whether we are doing an interface
1306 * typemanager.cs: Temporary hack until we get attributes in
1307 interfaces (Ravi is working on that) and we get IndexerName
1308 support in interfaces.
1310 * interface.cs: Register the indexers as properties.
1312 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
1313 warning, I have verified that this is a bug in the .NET runtime
1314 (JavaScript suffers of the same problem).
1316 * typemanager.cs (MemberLookup): When looking up members for
1317 interfaces, the parent of an interface is the implicit
1318 System.Object (so we succeed in searches of Object methods in an
1319 interface method invocation. Example: IEnumerable x; x.ToString
1322 2002-05-25 Miguel de Icaza <miguel@ximian.com>
1324 * class.cs (Event): Events should also register if they do
1325 implement the methods that an interface requires.
1327 * typemanager.cs (MemberLookup); use the new GetInterfaces
1330 (GetInterfaces): The code used to lookup interfaces for a type is
1331 used in more than one place, factor it here.
1333 * driver.cs: Track the errors at the bottom of the file, we kept
1336 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
1337 instance if the method we are calling is static!
1339 2002-05-24 Miguel de Icaza <miguel@ximian.com>
1341 * attribute.cs (ApplyAttributes): Make this function filter out
1342 the IndexerName attribute (as that attribute in reality is never
1343 applied) and return the string constant for the IndexerName
1346 * class.cs (TypeContainer.Emit): Validate that all the indexers
1347 have the same IndexerName attribute, and if so, set the
1348 DefaultName attribute on the class.
1350 * typemanager.cs: The return value might contain other stuff (not
1351 only methods). For instance, consider a method with an "Item"
1352 property and an Item method.
1354 * class.cs: If there is a problem with the parameter types,
1357 2002-05-24 Ravi Pratap <ravi@ximian.com>
1359 * ecore.cs (ImplicitConversionExists): Wrapper function which also
1360 looks at user defined conversion after making a call to
1361 StandardConversionExists - we need this for overload resolution.
1363 * expression.cs : Update accordingly the various method calls.
1365 This fixes 2 bugs filed against implicit user defined conversions
1367 2002-05-22 Miguel de Icaza <miguel@ximian.com>
1369 * statement.cs: Track the result of the assignment.
1371 2002-05-21 Miguel de Icaza <miguel@ximian.com>
1373 * expression.cs (MemberAccess): Improved error reporting for
1374 inaccessible members.
1376 2002-05-22 Martin Baulig <martin@gnome.org>
1378 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
1379 itself with debugging support.
1381 2002-05-22 Martin Baulig <martin@gnome.org>
1383 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
1384 Removed, this isn't needed anymore.
1386 2002-05-20 Martin Baulig <martin@gnome.org>
1388 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
1389 be underlying type for an enum.
1391 2002-05-20 Miguel de Icaza <miguel@ximian.com>
1393 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
1394 that splits out the loading of just the core types.
1396 * rootcontext.cs (ResolveCore): Split the struct resolution in
1397 two, so we can load the enumeration underlying types before any
1400 * expression.cs (Is): Bandaid until we fix properly Switch (see
1401 bug #24985 for details).
1403 * typemanager.cs (ImplementsInterface): The hashtable will contain
1404 a null if there are no interfaces implemented.
1406 2002-05-18 Miguel de Icaza <miguel@ximian.com>
1408 * cs-parser.jay (indexer_declarator): It is fine to have array
1411 2002-05-17 Miguel de Icaza <miguel@ximian.com>
1413 * typemanager.cs: (RegisterBuilder): New function used to register
1414 TypeBuilders that implement interfaces. Since
1415 TypeBuilder.GetInterfaces (as usual) does not work with lame
1417 (AddUserType): register interfaces.
1419 (ImplementsInterface): Use the builder_to_ifaces hash if we are
1420 dealing with TypeBuilder. Also, arrays are showing up as
1421 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
1422 methods can not be invoked on them!
1424 * ecore.cs (ExplicitReferenceConversionExists): Made public.
1425 (ImplicitReferenceConversionExists): Split out from
1426 StandardConversionExists.
1428 * expression.cs (As): We were only implementing one of the three
1429 cases for the as operator. We now implement them all.
1430 (Is): Implement the various other cases for Is as well.
1432 * typemanager.cs (CACHE): New define used to control if we want or
1433 not the FindMembers cache. Seems to have a negative impact on
1434 performance currently
1436 (MemberLookup): Nested types have full acess to
1437 enclosing type members
1439 Remove code that coped with instance/static returns for events, we
1440 now catch this in RealFindMembers.
1442 (RealFindMembers): only perform static lookup if the instance
1443 lookup did not return a type or an event.
1445 2002-05-17 Miguel de Icaza <miguel@ximian.com>
1447 * assign.cs (CompoundAssign): We pass more semantic information
1448 now to Compound Assignments than we did before: now we have all
1449 the information at hand, and now we resolve the target *before* we
1450 do the expression expansion, which allows the "CacheValue" method
1451 to have the effect we intended (before, a [x] += 1 would generate
1452 two differen ArrayAccess expressions from the ElementAccess,
1453 during the resolution process).
1455 (CompoundAssign.DoResolve): Resolve target and original_source here.
1457 2002-05-16 Miguel de Icaza <miguel@ximian.com>
1459 * expression.cs (ArrayAccess): dropped debugging information.
1461 * typemanager.cs: Small bug fix: I was always returning i_members,
1462 instead of one of i_members or s_members (depending on which had
1465 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
1466 method is invoked before any code generation takes place, and it
1467 is a mechanism to inform that the expression will be invoked more
1468 than once, and that the method should use temporary values to
1469 avoid having side effects
1471 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
1473 * ecore.cs (Expression.CacheTemporaries): Provide empty default
1476 * expression.cs (Indirection, ArrayAccess): Add support for
1477 CacheTemporaries in these two bad boys.
1479 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
1481 (StoreFromPtr): Handle stobj as well.
1483 * expression.cs (UnaryMutator): Share more code.
1485 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
1486 down: I was not tracking the Filter function as well, which
1487 was affecting the results of the cache.
1489 2002-05-15 Miguel de Icaza <miguel@ximian.com>
1491 * attribute.cs: Remove the hack to handle the CharSet property on
1494 2002-05-14 Miguel de Icaza <miguel@ximian.com>
1496 * attribute.cs (DoResolve): More uglyness, we now only try to
1497 resolve the attribute partially, to extract the CharSet
1498 information (only if we are a StructLayout attribute). Otherwise
1500 (GetExtraTypeInfo): Add some code to conditionally kill in the
1501 future this. I am more and more convinced that the .NET
1502 framework has special code to handle the attribute setting on
1505 * expression.cs (IsParamsMethodApplicable): Revert my previous
1506 foreach change here, it was wrong.
1508 2002-05-13 Miguel de Icaza <miguel@ximian.com>
1510 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
1511 (pp_expr): do not abort on unknown input, just return.
1512 (eval): abort if there are pending chars.
1514 * attribute.cs (Attribute.Resolve): Positional parameters are
1515 optional. Deal with that case.
1517 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
1518 the Ansi/Unicode/Auto information for the type.
1520 (TypeContainer.DefineType): instantiate the EmitContext here, as
1521 we will be using it during the type definition (to resolve
1522 attributes) and during the emit phase.
1524 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
1525 to pull type information out of the attributes
1527 (Attribute.Resolve): track the constructor builder, and allow for
1528 multiple invocations (structs and classes will use this).
1530 * ecore.cs (MemberLookupFinal): new version with all the
1531 parameters customizable.
1533 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
1534 constructors. Return if the result value is null (as the error
1535 would have been flagged already by MemberLookupFinal)
1537 Do not allow instances of abstract classes or interfaces to be
1540 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
1541 We have to compare the assembly property here when dealing with
1542 FamANDAssem and Assembly access modifiers, because we might be
1543 creating an assembly from *modules* (that means that we are not
1544 getting TypeBuilders for types defined in other modules that are
1545 part of this assembly).
1547 (Method.Emit): If the method is marked abstract and has a body,
1550 (TypeContainer.DefineMembers): If both the defined member and the
1551 parent name match are methods, then do not emit any warnings: let
1552 the Method.Define routine take care of flagging warnings. But if
1553 there is a mismatch (method overrides something else, or method is
1554 overriwritten by something, then emit warning).
1556 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
1557 set to null, this means `do not check for the return type on the
1560 (Method.Define): set the return type for the method signature to
1561 null, so that we get methods with the same name and parameters and
1562 different return types. This is used to flag warning 114 (you are
1563 hiding a method, and you probably want to use the new/override
1566 * typemanager.cs (MemberLookup): Implemented proper access
1567 control, closing a long standing set of bug reports. The problem
1568 was that the Framework only has two bits: Public and NonPublic,
1569 and NonPublic includes private and protected methods, but we need
1570 to enforce the FamANDAssem, FamOrAssem and Family.
1572 2002-05-11 Miguel de Icaza <miguel@ximian.com>
1574 * statement.cs (GotoCase): Return true: Ammounts to giving up
1575 knowledge on whether we return or not, and letting the other case
1576 be responsible for it.
1578 2002-05-10 Miguel de Icaza <miguel@ximian.com>
1580 * driver.cs: Do not load directories for each file processed, only
1581 do it if there is a pattern.
1583 * ecore.cs: Report readonly assigns here as well, as we might have
1584 been resolved only by MemberAccess.
1586 (SimpleName.SimpleNameResolve): Also be useful for LValue
1587 resolution. We need this to propagate assign to local readonly variables
1589 * typemanager.cs: Use a ptrhashtable for the criteria, because we
1590 do not want to reuse potential criteria memory.
1592 * class.cs (MyEventBuilder): Set reflected_type;
1594 * ecore.cs (Constantify): Added support for constifying bools.
1596 (RootContext.LookupType): Added a cache for values looked up in
1597 the declaration space.
1599 * typemanager.cs (FindMembers): Now is a front-end to
1600 RealFindMembers, and provides a two-level hashtable-based cache to
1603 15% performance improvement: from 22.5 to 19.2 seconds.
1605 * expression.cs (IsParamsMethodApplicable): use foreach.
1606 (Invocation.DoResolve): ditto.
1607 (New.DoResolve): ditto.
1608 (ArrayCreation.DoResolve): ditto.
1610 * ecore.cs (FindMostEncompassingType): use foreach.
1612 * delegate.cs (NewDelegate.DoResolve): Use foreach
1614 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
1615 (RemoveMethods): use foreach.
1617 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
1618 nested foreach statements instead of for, and also break out of
1619 the inner loop once a match is found.
1621 (Invocation.OverloadResolve): Use foreach, simplify the code.
1623 2002-05-08 Miguel de Icaza <miguel@ximian.com>
1625 * cfold.cs (BinaryFold): During an enumeration evaluation context,
1626 we actually unwrap the expression to allow for extra information
1629 * expression.cs: Use Shr_Un on unsigned operations.
1631 2002-05-08 Ravi Pratap <ravi@ximian.com>
1633 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
1634 applicable operators was not being considered correctly. This closes
1635 the bug Miguel reported.
1637 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
1639 * attribute.cs: check that the type derives from System.Attribute
1640 and report the correct error in that case (moved the duplicate code to
1641 its own method, too).
1643 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
1645 * attribute.cs: lookup attribute type name as the spec says: first the
1646 bare attribute name and then name + "Attribute" (nant compiles with
1647 mcs after this fix).
1649 2002-05-07 Miguel de Icaza <miguel@ximian.com>
1651 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
1652 Because of the way we parse things, we should try to see if a
1653 UIntConstant can fit in an integer.
1655 2002-05-07 Ravi Pratap <ravi@ximian.com>
1657 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
1658 when we are in an explicit context.
1660 (ConvertReferenceExplicit): When converting from Iface type S to Class
1661 T make sure the rules are implemented as an OR.
1663 * parameter.cs (ParameterType): Make it a property for now although the
1664 purpose really isn't anything immediate.
1666 * expression.cs (Is*Applicable): Do better checking on the parameter type
1667 of a ref/out parameter. The ones from the system assemblies are already
1668 marked with the correct type so we don't need to do any correction.
1670 * ecore.cs (StandardConversionExists): Conversion from Interface types to
1671 the object type is standard too so include that.
1673 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1675 * ecore.cs (StandardConversionExists): Augment with missing code:
1676 deal with IntConstant, LongConstants and Enumerations.
1678 * assign.cs: Report the error, instead of failing silently
1680 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
1681 typecontainer that they are declared, because the
1682 typecontainer/namespace will have the list of using clauses that
1685 Assembly Attributes were escaping the normal registration
1688 (EmitCode): Apply attributes within an EmitContext that represents
1689 the container they were declared on.
1691 * cs-parser.jay: Track bases for structs. How did I get this wrong?
1693 2002-05-06 Ravi Pratap <ravi@ximian.com>
1695 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
1696 Revamp completely - make much cleaner as we now operate only
1699 (FindMostSpecificSource, FindMostSpecificTarget): New methods
1700 to implement the logic detailed in the spec more correctly.
1702 (UserDefinedConversion): Update accordingly.
1704 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1706 * statement.cs: Return flow analysis information up.
1708 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
1711 (token): Do not consume an extra character before calling
1714 2002-05-06 Piers Haken <piersh@friskit.com>
1716 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
1718 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1720 * class.cs (Constructor.Emit): Set the IsStatic flag in the
1721 EmitContext during the instance constructor initializer
1722 resolution, to stop access to instance variables.
1724 This is mandated by the spec, last paragraph of the `constructor
1725 initializers' section.
1727 2002-05-05 Miguel de Icaza <miguel@ximian.com>
1729 * cs-parser.jay, class.cs (Accessor): new class used to represent
1730 an accessor (get or set). In the past we used `null' to represent
1731 a missing accessor. But this is ambiguous because there was no
1732 way to tell in abstract indexers/properties if one of them was
1735 Now there is a way of addressing that.
1737 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
1738 instead of FindMembers.
1740 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
1741 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
1743 * attribute.cs: Treat indexers and properties as the same in terms
1744 of applying attributes
1746 * ecore.cs (FindMostEncompassedType): Use statically initialized
1747 EmptyExpressions()s like we do elsewhere to avoid creating useless
1748 objects (and we take this out of the tight loop).
1750 (GetConversionOperators): Move the code to extract the actual
1751 operators to a separate routine to clean things up.
1753 2002-05-04 Miguel de Icaza <miguel@ximian.com>
1755 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
1756 events are always registered FieldBuilders.
1758 * class.cs (FieldBase): New class shared by Fields
1760 * delegate.cs: If we are a toplevel delegate, use our full name.
1761 If we are a nested delegate, then only use our tail name.
1763 2002-05-02 Ravi Pratap <ravi@ximian.com>
1765 * expression.cs (IsApplicable): Ensure that we add the "&" to
1766 ref/out types before comparing it with the type of the argument.
1768 (IsParamsMethodApplicable): Ditto.
1770 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
1773 * delegate.cs : Handle the case when we have more than one applicable
1774 method. Flag an error only when we finish checking all.
1776 2002-05-02 Miguel de Icaza <miguel@ximian.com>
1778 * expression.cs: Add support for boolean static initializers.
1780 2002-05-01 Miguel de Icaza <miguel@ximian.com>
1782 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
1784 * parameter.cs (ComputeParameterTypes,
1785 ComputeAndDefineParameterTypes): Better error handling: now we
1786 clear the `types' cache if we fail during any of the type lookups.
1787 We also return the status code correctly to our caller
1789 * delegate.cs: If we fail to define a delegate, abort the extra
1792 * expression.cs (Binary.ResolveOperator): for
1793 operator==(object,object) and operator !=(object, object) we also
1794 have to verify that there is an implicit conversion from one to
1797 (ArrayAccess.DoResolve): Array Access can operate on
1800 2002-04-30 Miguel de Icaza <miguel@ximian.com>
1802 * assign.cs (CompoundAssign): A new class used as a "flag" that
1803 the assignment actually is happening as part of a compound
1804 assignment operator.
1806 During compound assignment, a few new rules exist to enable things
1813 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
1814 to the type of x) if y is implicitly convertible to the type of x,
1815 and the operator is a builtin operator and the return type of the
1816 operator is explicitly convertible to the type of x.
1818 * rootcontext.cs: Reset warning level to 2. 4 catches various
1819 "interesting" features in mcs, we must clean this up at some
1820 point, but currently am trying to kill other bugs ;-)
1822 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
1823 in container classes as well.
1825 * expression.cs (Binary.ResolveOperator): Handle string case
1826 before anything else (as operator overloading does emit an error
1827 before doing anything else).
1829 This code could go away when we move to a table driven model, but
1830 i could not come up with a good plan last night.
1832 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
1834 * typemanager.cs (CSharpName): reimplementation using regex.
1835 * class.cs: added null check for fields in Emit
1836 * rootcontext.cs: set warninglevel to 4
1838 2002-04-29 Miguel de Icaza <miguel@ximian.com>
1840 * typemanager.cs (CSharpName): reimplemented with Lupus
1843 2002-04-28 Miguel de Icaza <miguel@ximian.com>
1845 * statement.cs (If): correclty implement Resolve, because we were
1846 not catching sem errors in there. The same process is needed
1848 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
1851 (Statement.Warning_DeadCodeFound): Factorize code.
1852 (While): Report dead code here too.
1854 (Statement): Added Resolve virtual method to allow
1855 for resolution split from the emit code.
1857 2002-04-26 Miguel de Icaza <miguel@ximian.com>
1859 * statement.cs (EmitBoolExpression): No longer try to resolve the
1861 (MakeBoolean): New utility function that resolve, implicitly
1862 converts to boolean and tags the expression.
1865 (If, Do): Implement dead code elimination.
1866 (While): Implement loop inversion
1868 (Do, While, For, If): Resolve the expression prior to calling our
1871 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
1874 - added method Report28 (warning: program has more than one entry point)
1875 - added method IsEntryPoint, implements paragraph 10.1 of the spec
1876 - modified method Method.Define, the part at the end of the method
1878 * rootcontext.cs: added static public Location EntryPointLocation;
1880 * ../errors/cs0028.cs : Add test case for the above warning.
1883 - modified method CSharpName to allow arrays of primitive type to
1884 be printed nicely (e.g. instead of System.Int32[][] it now prints
1886 - added method CSharpSignature: returns the signature of a method
1887 in string format to be used in reporting errors, warnings, etc.
1889 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
1892 2002-04-26 Ravi Pratap <ravi@ximian.com>
1894 * delegate.cs (Define): Fix extremely silly bug where I was
1895 setting the type of the 'object' parameter of the BeginInvoke
1896 method to System.IAsyncResult instead of System.Object ;-)
1898 2002-04-26 Miguel de Icaza <miguel@ximian.com>
1900 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
1903 (Constructor.Emit): return if we fail to initialize the
1904 constructor. Another door closed!
1906 * expression.cs (New.DoResolve): Improve error message (from -6 to
1907 1501). Use DeclaredOnly lookup to find the exact constructor.
1909 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
1910 loop. This is useful.
1912 * cs-parser.jay: Adjust the default parameters so that destructors
1913 have the proper signature.
1915 2002-04-26 Martin Baulig <martin@gnome.org>
1917 * driver.cs (LoadAssembly): If `assembly' contains any characters
1918 which are only valid in path names and not in assembly names
1919 (currently slash, backslash and point), use Assembly.LoadFrom ()
1920 instead of Assembly.Load () on the `assembly' (before iteration
1921 over the link_paths).
1923 2002-04-26 Martin Baulig <martin@gnome.org>
1925 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
1927 2002-04-25 Miguel de Icaza <miguel@ximian.com>
1929 * class.cs (Property): use the new typemanager.MemberLookup
1931 (TypeContainer.MemberLookup): Implement using the
1932 TypeManager.MemberLookup now.
1934 * typemanager.cs: Make MemberLookup a function of the TypeManager,
1935 and return MemberInfos, so that these can be used without an
1936 EmitContext (what we had before).
1938 2002-04-24 Miguel de Icaza <miguel@ximian.com>
1940 * expression.cs: Fix the case where the argument to params if the
1941 type of the params. I omitted handling this before. Fixed
1943 2002-04-22 Miguel de Icaza <miguel@ximian.com>
1945 * driver.cs: Call BootCorlib_PopulateCoreType
1947 * class.cs (Property.CheckBase): Check for properties only, not
1950 * interface.cs: Temporary hack: try/catch around the
1951 CustomAttributeBuilder, because I am getting an exception that I
1954 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
1955 types whose definitions are required to be there (attributes are
1956 defined before standard types).
1958 Compute definitions as we boot the various types, as they are used
1959 immediately (value_type class will need object_type, but if we do
1960 not initialize object_type, we will pass a null, which will let
1961 the runtime pick the System.Object from the existing corlib, which
1962 is not what we want).
1964 2002-04-22 Patrik Torstensson <totte@labs2.com>
1966 * cs-tokenizer.cs: fixed a number of trim() issues.
1968 2002-04-22 Ravi Pratap <ravi@ximian.com>
1970 * expression.cs (Argument.Type): Ensure that we return the correct
1971 type when we have out or ref parameters [in which case we
1974 2002-04-22 Miguel de Icaza <miguel@ximian.com>
1976 * class.cs (Property, Indexer): Allow extern modifier in there.
1978 * typemanager.cs (InitBaseTypes): Initializes object_type and
1979 value_type, since those will be used early on during the bootstrap
1980 process to compile corlib.
1982 (InitCoreTypes): Move code from here to InitBaseTypes.
1984 2002-04-21 Miguel de Icaza <miguel@ximian.com>
1986 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
1987 single-dimension arrays as using the ldlen opcode.
1989 Daniel Lewis discovered this optimization.
1991 * typemanager.cs: Add signature for System.Array::get_Length
1993 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1995 * statement.cs: report the error when the foreach does not apply to an
1996 array nor a collection.
1998 2002-04-19 Miguel de Icaza <miguel@ximian.com>
2000 * expression.cs: Add implicit conversions to the operator ~.
2002 * constant.cs (DecimalConstant.Emit): Emit decimal value.
2004 * typemanager.cs: Locate the decimal constructor.
2006 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2008 * attribute.cs: use the new property of TypeOf.
2009 * expression.cs: added 'get' property around typearg.
2011 These changes fix a build breaker reported by NickD. Is this the
2012 correct way to fix? If not, please, revert my changes and make it
2015 2002-04-17 Miguel de Icaza <miguel@ximian.com>
2017 * attribute.cs: Add support for typeof in attribute invocations.
2018 I am not sure that this is right though.
2020 2002-04-14 Duncan Mak <duncan@ximian.com>
2022 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
2023 Binary.Operator.Division case.
2025 2002-04-13 Ravi Pratap <ravi@ximian.com>
2027 * class.cs (DefineType): Ensure that we do a proper check on
2028 attribute types and also register it with the TypeManager.
2030 (TypeContainer.Targets): The default for attribute types is
2031 AttributeTargets.All.
2033 * attribute.cs (ApplyAttributes): Registering the attribute type
2034 is done elsewhere, not when we discover we have a Usage attribute.
2036 2002-04-12 Ravi Pratap <ravi@ximian.com>
2038 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
2039 and get rid of is_delegate parameter.
2041 * everywhere : update.
2043 2002-04-12 Ravi Pratap <ravi@ximian.com>
2045 * cs-parser.jay (compilation_unit): Revamp completely to use
2046 some new ideas that I got from Rhys' grammar to solve the problems
2047 with assembly level attributes.
2049 (outer_declaration): New grammar production.
2051 (attribute_sections): Add.
2053 (opt_attributes): Base on attribute_sections
2055 (namespace_declaration): Allow opt_attributes to tackle the case
2056 when we have assembly level attributes - we are clever in this
2059 * attribute.cs (ApplyAttributes): Do not worry about assembly
2060 attributes in the non-global context.
2062 * rootcontext.cs (AddGlobalAttributes): Go back to using this
2063 instead of SetGlobalAttributes.
2065 * class.cs, rootcontext.cs : Ensure we define and generate
2066 attribute types before anything else.
2068 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
2069 and flag the new error -20 for the case when the attribute type
2070 does not have valid targets specified. csc does not catch this.
2072 * ../errors/errors.txt : update for error # -20
2074 2002-04-11 Ravi Pratap <ravi@ximian.com>
2076 * support.cs (InternalParameters.ParameterModifier): Do some null
2077 checking and return sane values.
2079 * class.cs (Method.Define): If we are a PInvoke method, ensure
2080 that we are static and extern. Report error # 601
2082 * ../errors/cs0601.cs : Add test case for the above error.
2084 2002-04-07 Ravi Pratap <ravi@ximian.com>
2086 * rootcontext.cs (attribute_types): We need to keep type of
2087 all attribute types separately and emit code for them first.
2089 (RegisterAttribute) : Implement.
2091 * class.cs (DefineType): Check if the current Type is a custom
2092 attribute type and register it accordingly.
2094 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
2095 adding the first attribute twice and rename to
2097 (SetGlobalAttributes): this.
2099 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
2102 * attribute.cs (ApplyAttributes): Take an additional argument telling us
2103 if we are processing global arguments. Hmm, I am unsure of this.
2105 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2107 * expression.cs: added static array of strings to avoid calling
2108 Enum.ToString () for Operator in Binary. Significant recover of
2111 2002-04-10 Miguel de Icaza <miguel@ximian.com>
2113 * class.cs (FindMembers): Allow the Builders of the various
2114 members to be null. If they are skip them. This only happens
2115 during the PInvoke declaration.
2117 2002-04-09 Miguel de Icaza <miguel@ximian.com>
2119 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
2120 failure, so we do not keep going afterwards.
2122 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
2123 wanted to pass `false' as the `is_delegate' argument. If this is
2124 the case, why not use delegate_type == null to mean `is_delegate =
2125 false' and anything else as is_delegate = true.
2127 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
2129 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
2130 code for the section, not the beginning of the tests.
2132 2002-04-08 Miguel de Icaza <miguel@ximian.com>
2134 * cfold.cs: Handle operator + (Enum x, Underlying x)
2136 * expression.cs (Binary): same. Warn about errors where we have
2137 Enum/Enum in operator + as well.
2139 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
2142 - added support for switch(bool)
2143 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
2144 - add TableSwitchEmit() to handle table-based switch statements
2146 2002-04-05 Ravi Pratap <ravi@ximian.com>
2148 * expression.cs (Invocation.OverloadResolve): Factor out code which
2149 does parameter compatibility checking with arguments so that we can
2150 re-use the code even from Delegate.VerifyApplicability
2152 (VerifyArgumentsCompat): Move above code here.
2154 * delegate.cs (VerifyApplicability): Get rid of duplicate code
2155 and instead make a call to the above method.
2157 2002-03-31 Ravi Pratap <ravi@ximian.com>
2159 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
2160 We use it to keep track of classes which are attribute types.
2162 2002-04-02 Miguel de Icaza <miguel@ximian.com>
2164 * delegate.cs (Delegate.Define): Correctly define the types in the
2165 presence of fixed and array parameters.
2167 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
2170 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
2171 include NonPublic after the first iteration.
2173 * class.cs (Indexer.CheckBase): Only check if both parents are
2176 * cs-parser.jay (accessor_body): If empty, set to null.
2178 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
2179 same code path here to resolve constants names that we did have in
2180 MemberAccess.DoResolve. There is too much code duplicated here.
2182 2002-04-01 Miguel de Icaza <miguel@ximian.com>
2184 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
2186 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
2189 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
2190 tokens, numbers and strings.
2192 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
2195 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
2196 asyncronous parameters and the regular parameters.
2198 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
2199 specify the target directory.
2201 * expression.cs: (This.DoResolve): Simplify
2202 (As.Emit): Optimize, do not generate IsInst if the expression is
2203 always of the given type.
2205 (Is.DoResolve): Bug fix, we were reporting both always/never for
2208 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
2209 creating too many unnecessary arrays.
2211 2002-03-31 Miguel de Icaza <miguel@ximian.com>
2213 * class.cs (EmitFieldInitializer): Use Assign expression to assign
2214 fields instead of rolling our own initializer. Takes care of all
2215 implicit conversions, and drops unnecessary static checks/argument.
2217 2002-03-31 Dick Porter <dick@ximian.com>
2219 * driver.cs: use the GetDirectories() return values properly, and
2220 use "/" as path separator.
2222 2002-03-30 Miguel de Icaza <miguel@ximian.com>
2224 * expression.cs (Unary): Optimize - - expr into expr.
2225 (Binary): Optimize a + (-b) into a -b.
2227 * codegen.cs (CodeGen): Made all methods static.
2229 2002-03-29 Miguel de Icaza <miguel@ximian.com>
2233 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
2234 TypeBuilder property.
2236 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
2239 * tree.cs: Removed the various RecordXXXX, and replaced with a
2240 single RecordDecl. Removed all the accessor methods, and just
2241 left a single access point Type
2243 * enum.cs: Rename DefineEnum to DefineType.
2245 * decl.cs: New abstract method `DefineType' used to unify the
2246 Defines for Enumerations, Interfaces, TypeContainers and
2249 (FindType): Moved LookupInterfaceOrClass here. Moved the
2250 LookupBaseClasses method that used to live in class.cs and
2251 interface.cs here, and renamed to FindType.
2253 * delegate.cs: Implement DefineType. Take advantage of the
2254 refactored pattern for locating the parent builder without taking
2255 the parent_builder argument (which we know does not work if we are
2256 nested, and triggering a toplevel definition).
2258 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2260 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
2261 accessibility of a member has changed during override and report
2264 * class.cs (Method.Define, Property.Define): Only complain on
2265 overrides if the method is private, any other accessibility is
2266 fine (and since we just checked the permission is the same, we are
2269 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
2270 and elif are processed always. The other pre-processing
2271 directives are only processed if we are "taking" the path
2273 2002-03-29 Martin Baulig <martin@gnome.org>
2275 * class.cs (Method.Emit): Only emit symbolic debugging info if the
2276 current location is not Null.
2278 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
2279 a separate method so we can profile it.
2281 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
2282 `span.Seconds' are just seconds, but no minutes or hours.
2283 (MainDriver): Profile the CodeGen.SaveSymbols calls.
2285 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2287 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
2288 Remove the gratuitous set of Final:
2290 // If an interface implementation, then we can set Final.
2291 if (((flags & MethodAttributes.Abstract) == 0) &&
2292 implementing.DeclaringType.IsInterface)
2293 flags |= MethodAttributes.Final;
2295 I do not know what I was smoking when I used that.
2298 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
2299 step into fixing the name resolution issues for delegates and
2300 unifying the toplevel name resolution.
2302 2002-03-28 Martin Baulig <martin@gnome.org>
2304 * class.cs (Method.Emit): If we have a symbol writer, call its
2305 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
2306 tell it about the current method.
2308 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
2309 writer that we're going to emit the first byte of IL code for a new
2310 statement (a new source line).
2311 (EmitContext.EmitTopBlock): If we have a symbol writer, call
2312 EmitContext.Mark() before emitting any code.
2314 * location.cs (SymbolDocument): Return null when we're Null.
2316 * statement.cs (Statement): Moved the `Location loc' variable here.
2317 (Statement.EmitBoolExpression): If we have a symbol writer, call
2318 ec.Mark() before emitting any code to tell it that we're at the
2319 beginning of a new statement.
2320 (StatementExpression): Added `Location' argument to the constructor.
2321 (Block): Added public readonly variable `StartLocation' and public
2322 variable `EndLocation'. The latter is to be set using SetEndLocation().
2323 (Block): Added constructor which takes a start and end location.
2324 (Block.SetEndLocation): New method. This sets the end location.
2325 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
2326 local variables we create.
2327 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
2328 each statement and do also mark the begin and end of the block.
2330 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
2331 tell it the current lexer.Location, use Location.Null for the end of the
2333 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
2334 current block, set its end location using SetEndLocation().
2335 (statement_expression): StatementExpression constructor now takes the
2336 lexer.Location as additional argument.
2337 (for_statement, declare_local_variables): Likewise.
2338 (declare_local_variables): When creating a new implicit block, use the
2339 new Block constructor and pass it the lexer.Location.
2341 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2343 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
2344 members also on the parent interfaces recursively.
2346 2002-03-27 Miguel de Icaza <miguel@ximian.com>
2348 * report.cs: Use new formats, since Gonzalo finished the missing
2351 * expression.cs (Binary.ResolveOperator): added missing operator|
2352 operator& and operator^ for bool/bool.
2354 * cs-parser.jay: CheckDef now takes a Location argument that is
2355 used to report errors more precisly (instead of reporting the end
2356 of a definition, we try to track something which is a lot closer
2357 to the source of the problem).
2359 * cs-tokenizer.cs: Track global token use, so we can properly flag
2360 the use of #define/#undef after the first token has been seen.
2362 Also, rename the reportXXXX to Error_DescriptiveName
2364 * decl.cs (DeclSpace.IsTopLevel): Move property here from
2365 TypeContainer, so that Enum and Interface can use this too.
2367 * class.cs (TypeContainer.LookupInterfaceOrClass,
2368 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
2369 `builder' argument. Typically this was used to pass the parent
2370 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
2373 The problem is that a nested class could trigger the definition of
2374 a toplevel class, and the builder would be obviously wrong in that
2377 So we drop this argument, and we compute dynamically the
2378 TypeBuilder/ModuleBuilder (the correct information was available
2379 to us anyways from DeclSpace.Parent)
2381 * interface.cs (Interface.DefineInterface): Drop builder
2382 parameter cleanup like class.cs
2384 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
2387 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
2390 (Try.Emit): Propagate the returns value from the statement.
2392 (Return.Emit): Even if we are leavning
2394 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
2396 * modifiers.cs: Fix the computation of MethodAttributes flags.
2398 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
2400 * driver.cs: allow compilation of files that start with '/'.
2401 Add a default case when checking the argument of --target.
2403 2002-03-25 Miguel de Icaza <miguel@ximian.com>
2405 * interface.cs: Implement the same search algorithm for types in
2408 * delegate.cs: Do not allow multiple definition.
2410 * Recovered ChangeLog that got accidentally amputated
2412 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
2414 * rootcontext.cs: Load manually enum to allow core classes to
2415 contain enumerations.
2417 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
2418 Update to new static methods in TypeManager.
2420 * typemanager.cs (GetMethod, GetConstructor): Use our
2421 implementation of FindMembers to find the members, since during
2422 corlib compilation, the types are TypeBuilders and GetMethod and
2423 GetConstructor do not work.
2425 Make all methods in TypeManager static.
2427 (InitCodeHelpers): Split the functionality from
2428 the InitCodeTypes function.
2430 * driver.cs: Call InitCodeHelpers after we have populated the
2433 * cs-parser.jay (delegate_declaration): we did not used to compute
2434 the delegate name correctly for void delegates.
2436 2002-03-24 Miguel de Icaza <miguel@ximian.com>
2438 * rootcontext.cs (RootContext): Init the interface_resolve_order
2439 and type_container_resolve_order always.
2441 (ResolveCore, BootstrapCorlib_ResolveClass,
2442 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
2443 compiler when compiling with --nostdlib
2445 * class.cs (TypeContainer.DefineType): Check that our parent is
2446 not null. This test is most important when we are bootstraping
2449 * codegen.cs: Split out the symbol writing code.
2451 2002-03-25 Martin Baulig <martin@gnome.org>
2453 * driver.cs (-g): Made -g an alias for --debug.
2455 2002-03-24 Martin Baulig <martin@gnome.org>
2457 * codegen.cs (SymbolWriter): New public variable. Returns the
2458 current symbol writer.
2459 (CodeGen): Added `bool want_debugging_support' argument to the
2460 constructor. If true, tell the ModuleBuild that we want debugging
2461 support and ask it for the ISymbolWriter.
2462 (Save): If we have a symbol writer, call it's Close() method after
2463 saving the assembly.
2465 * driver.c (--debug): New command line argument to create a
2466 debugger information file.
2468 * location.cs (SymbolDocument): New public property. Returns an
2469 ISymbolDocumentWriter object for the current source file or null
2470 if we don't have a symbol writer.
2472 2002-03-21 Miguel de Icaza <miguel@ximian.com>
2474 * driver.cs (LoadAssembly): Correctly return when all the paths
2475 have been tried and not before.
2477 * statement.cs (Switch.Emit): return the actual coverage for this
2478 statement (returns/not-returns)
2480 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
2481 switch of the statement if we are the last switch section. That
2482 kills two problems: try/catch problems (we used to emit an empty
2483 nop at the end) and switch statements where all branches would
2486 2002-03-19 Miguel de Icaza <miguel@ximian.com>
2488 * driver.cs: Add default assemblies (the equivalent to the
2489 Microsoft CSC.RSP file)
2491 * cs-tokenizer.cs: When updating `cols and setting it to zero,
2492 also update tokens_seen and set it to false.
2494 * driver.cs: Implement --recurse for Mike.
2496 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
2497 correctly splitting out the paths.
2499 2002-03-18 Miguel de Icaza <miguel@ximian.com>
2501 * interface.cs (Interface.PopulateProperty): Instead of using
2502 `parent' as the declaration space for the set parameters, use
2505 * support.cs (InternalParameters): InternalParameters constructor
2506 takes a DeclSpace instead of a TypeContainer.
2508 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
2509 types are being initialized, load the address of it before calling
2512 (New): Provide a mechanism to disable the generation of local
2513 value type temporaries when the caller will be providing us with
2514 an address to store it.
2516 (ArrayCreation.EmitDynamicInitializers): Use it.
2518 2002-03-17 Miguel de Icaza <miguel@ximian.com>
2520 * expression.cs (Invocation.EmitArguments): Only probe for array
2521 property if there is more than one argument. Sorry about that.
2523 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
2526 * class.cs (Method.LabelParameters): Fix incorrect code path that
2527 prevented the `ParamArrayAttribute' from being applied to the
2530 2002-03-16 Miguel de Icaza <miguel@ximian.com>
2532 * support.cs (ReflectionParameters): Correctly compute whether the
2533 last argument is a params array. Fixes the problem with
2536 * typemanager.cs: Make the assemblies array always be non-null
2537 (empty, but non-null)
2539 * tree.cs (RecordDecl): New function that abstracts the recording
2540 of names. This reports error 101, and provides a pointer to the
2541 previous declaration. Fixes a crash in the compiler.
2543 * cs-parser.jay (constructor_declaration): Update to new grammar,
2544 and provide a constructor_body that can be empty.
2546 2002-03-15 Miguel de Icaza <miguel@ximian.com>
2548 * driver.cs: Add support for --resources.
2550 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
2551 Make all types for the various array helper methods be integer.
2553 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
2554 CheckState to ConvCast.
2556 (ConvCast): Now it takes a `checked' state argument, to avoid
2557 depending on the emit context for the conversion, and just using
2558 the resolve time setting.
2560 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
2561 instead of Invocation.EmitArguments. We do not emit the original
2562 arguments, instead we emit those which have been converted to
2563 unsigned int expressions.
2565 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
2567 * codegen.cs: ditto.
2569 * expression.cs (LocalVariableReference): Drop the use of the
2570 Store function that depended on the variable index.
2572 * statement.cs (VariableInfo): Drop the `Idx' property from this
2573 class, as this is not taking into account the indexes for
2574 temporaries tat we generate during the execution, getting the
2577 * class.cs: First emit class initializers, then call the parent
2580 * expression.cs (Binary): Fix opcode emision.
2581 (UnaryMutator.EmitCode): Support checked code generation
2583 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
2584 matches for events for both the Static and Instance scans,
2585 pointing to the same element. Fix that.
2587 2002-03-14 Miguel de Icaza <miguel@ximian.com>
2589 * rootcontext.cs (ResolveTree): Always set the
2590 interface_resolve_order, because nested interfaces will be calling
2593 * class.cs (GetInterfaceOrClass): Track the same resolution
2594 process used by TypeManager.LookupType. This fixes the nested
2595 type lookups in class declarations (separate path from
2598 (TypeContainer.DefineType): Also define nested interfaces.
2599 (TypeContainer.RegisterOrder): New public function used to
2600 register the order in which child interfaces need to be closed.
2602 Nested interfaces need to be closed after their parents have been
2605 * interface.cs (InterfaceAttr): Put all the logic for computing
2606 the interface attribute here.
2608 (DefineInterface): Register our interface order with the
2609 RootContext or with the TypeContainer depending on the case.
2611 2002-03-12 Miguel de Icaza <miguel@ximian.com>
2613 * cs-parser.jay: rework foreach statement to work with the new
2614 changes to the policy on SimpleNames.
2616 * report.cs: support Stacktrace on warnings as well.
2618 * makefile: drop --unsafe and /unsafe from the compile.
2620 2002-03-13 Ravi Pratap <ravi@ximian.com>
2622 * ecore.cs (StandardConversionExists): Modify to take an Expression
2623 as the first parameter. Ensure we do null -> reference type conversion
2626 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
2627 temporary Expression objects.
2629 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
2631 * interface.cs: workaround bug in method overloading resolution
2632 (there is already a bugzilla bug for it).
2634 2002-03-12 Miguel de Icaza <miguel@ximian.com>
2636 We could also solve this problem by having a separate path for
2637 performing type lookups, instead of DoResolve, we could have a
2638 ResolveType entry point, and only participating pieces of the
2639 production (simplename, deref, array) would implement this.
2641 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
2642 signal SimpleName to only resolve type names and not attempt to
2643 resolve anything else.
2645 * expression.cs (Cast): Set the flag.
2647 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
2649 * class.cs: Only report 108 if there is no `new' modifier.
2651 * cs-parser.jay: rework foreach statement to work with the new
2652 changes to the policy on SimpleNames.
2654 * report.cs: support Stacktrace on warnings as well.
2656 * makefile: drop --unsafe and /unsafe from the compile.
2658 2002-03-11 Miguel de Icaza <miguel@ximian.com>
2660 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
2661 lookups here, instead of doing that at parse time. This means
2662 that our grammar will not introduce `LocalVariableReferences' as
2663 expressions at this point. That solves the problem of code like
2671 This is only half the fix. The full fix requires parameters to
2672 also be handled in this way.
2674 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
2675 makes the use more obvious of the DeclSpace. The
2676 ec.TypeContainer.TypeBuilder is now only used to pull the
2679 My theory is that I can get rid of the TypeBuilder completely from
2680 the EmitContext, and have typecasts where it is used (from
2681 DeclSpace to where it matters).
2683 The only pending problem is that the code that implements Aliases
2684 is on TypeContainer, and probably should go in DeclSpace.
2686 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
2687 lookups here, instead of doing that at parse time. This means
2688 that our grammar will not introduce `LocalVariableReferences' as
2689 expressions at this point. That solves the problem of code like
2697 This is only half the fix. The full fix requires parameters to
2698 also be handled in this way.
2700 * class.cs (Property.DefineMethod): When implementing an interface
2701 method, set newslot, when implementing an abstract method, do not
2702 set the flag (before we tried never setting it, or always setting
2703 it, which is the difference).
2704 (Indexer.DefineMethod): same.
2705 (Method.DefineMethod): same.
2707 * ecore.cs: Only set the status used flag if we get back a Field.
2709 * attribute.cs: Temporary hack, so Paolo can keep working.
2711 2002-03-08 Ravi Pratap <ravi@ximian.com>
2713 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
2714 the unmanaged type in the case we have a MarshalAs attribute.
2716 (Resolve): Handle the case when we are parsing the special MarshalAs
2717 attribute [we need to store the unmanaged type to use later]
2719 * typemanager.cs (marshal_as_attr_type): Built in type for the
2720 MarshalAs Attribute.
2722 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
2723 on parameters and accordingly set the marshalling info.
2725 2002-03-09 Miguel de Icaza <miguel@ximian.com>
2727 * class.cs: Optimizing slightly by removing redundant code after
2728 we switched to the `NoTypes' return value.
2729 (Property.DefineMethod): use NoTypes here too.
2731 This fixes the bug I introduced in my last batch of changes.
2733 2002-03-05 Ravi Pratap <ravi@ximian.com>
2735 * tree.cs (RecordEnum): Add. We now keep track of enums too.
2737 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
2738 Enums since those are types too.
2740 * cs-parser.jay (enum_declaration): Record enums as we parse them.
2742 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
2743 thanks to a call during the lookup process.
2745 2002-03-07 Miguel de Icaza <miguel@ximian.com>
2747 * statement.cs (Foreach): Lots of work to accomodate a particular
2748 kind of foreach statement that I had not kept in mind. It is
2749 possible to have foreachs on classes that provide a GetEnumerator
2750 method that return objects that implement the "pattern" for using
2751 a foreach, there is no need to support GetEnumerator
2754 This is needed to compile nant.
2756 * decl.cs: Only report 114 if the member is not `Finalize' and if
2757 the warning level is at least 2.
2759 * class.cs: Moved the compare function from Method to
2762 (MethodSignature.InheritableMemberSignatureCompare): Add new
2763 filter function that is used to extract inheritable methods from a
2766 (Method.Define): Use the new `inheritable_method_signature_filter'
2769 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
2772 2002-03-06 Miguel de Icaza <miguel@ximian.com>
2774 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
2776 * cs-parser.jay: Add opt_semicolon to the interface declaration.
2778 * expression.cs: Pass location information to
2779 ConvertImplicitStandard.
2781 * class.cs: Added debugging code to track return values from
2784 2002-03-05 Miguel de Icaza <miguel@ximian.com>
2786 * expression.cs (Is.DoResolve): If either side of the `is' is an
2787 interface, do not flag the warning.
2789 * ecore.cs (ImplicitReferenceConversion): We need a separate test
2792 * report.cs: Allow for --fatal to be used with --probe.
2794 * typemanager.cs (NoTypes): Move the definition for the empty Type
2797 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
2799 (TypeContainer.DefineProxy): New function used to proxy to parent
2800 implementations when implementing interfaces.
2801 (TypeContainer.ParentImplements): used to lookup if our parent
2802 implements a public function that is required by an interface.
2803 (TypeContainer.VerifyPendingMethods): Hook this up.
2805 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
2806 `modules' and `assemblies' arraylists into arrays. We only grow
2807 these are the very early start up of the program, so this improves
2808 the speedof LookupType (nicely measured).
2810 * expression.cs (MakeByteBlob): Replaced unsafe code with
2811 BitConverter, as suggested by Paolo.
2813 * cfold.cs (ConstantFold.Binary): Special case: perform constant
2814 folding of string concatenation, but if either side is a string,
2815 and the other is not, then return null, and let the runtime use
2816 the concatenation on the string plus the object (using
2819 2002-03-04 Miguel de Icaza <miguel@ximian.com>
2821 Constant Folding has been implemented now.
2823 * expression.cs (Unary.Reduce): Do not throw an exception, catch
2824 the error instead on types that are not supported in one's
2827 * constant.cs (Constant and all children): New set of functions to
2828 perform implict and explicit conversions.
2830 * ecore.cs (EnumConstant): Implement the new functions to perform
2831 conversion by proxying to the child expression.
2833 * codegen.cs: (ConstantCheckState): Constant evaluation has its
2834 own separate setting that can not be turned off from the command
2835 line using --unchecked or --checked and is only controlled using
2836 the checked/unchecked statements and expressions. This setting is
2837 used by the constant folder to flag errors.
2839 * expression.cs (CheckedExpr, UncheckedExpr): Set the
2840 ConstantCheckState as well.
2842 During Resolve, they also have to flag the state, because the
2843 constant folder runs completely in the Resolve phase.
2845 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
2848 2002-03-01 Miguel de Icaza <miguel@ximian.com>
2850 * cfold.cs: New file, this file contains the constant folder.
2852 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
2853 argument to track whether we are using the resulting address to
2854 load or store a value and provide better error messages.
2856 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
2857 new AddressOf arguments.
2859 * statement.cs (Foreach.EmitCollectionForeach): Update
2861 * expression.cs (Argument.Emit): Call AddressOf with proper
2862 arguments to track usage.
2864 (New.DoEmit): Call AddressOf with new arguments.
2866 (Unary.Emit): Adjust AddressOf call.
2868 2002-03-01 Ravi Pratap <ravi@ximian.com>
2870 * cs-parser.jay (member_access): Change the case for pre-defined types
2871 to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
2874 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
2877 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
2878 essentially like methods and apply attributes like MethodImplOptions to them too.
2880 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
2883 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
2884 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
2887 * Update code everywhere accordingly.
2889 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
2891 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
2893 2002-02-28 Ravi Pratap <ravi@ximian.com>
2895 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
2896 try performing lookups against those instead of jumping straight into using
2897 the 'using' clauses.
2899 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
2901 (LookupType): Perform lookups in implicit parents too.
2903 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
2904 sequence as RootContext.LookupType.
2906 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
2907 the various cases of namespace lookups into this method.
2909 2002-03-01 Miguel de Icaza <miguel@ximian.com>
2911 * cs-parser.jay: Add support for [Attribute ()] (empty arguments
2912 in positional arguments)
2914 * class.cs (Operator): Update the AllowedModifiers to contain
2917 * cs-parser.jay: Update operator declaration to allow for the
2918 operator body to be empty.
2920 * cs-tokenizer.cs: Added '\u' unicode support in strings and hex
2923 2002-02-27 Miguel de Icaza <miguel@ximian.com>
2925 * class.cs (Method.Emit): Label parameters.
2927 * driver.cs: Return 1 or 0 as the program exit code.
2929 2002-02-26 Miguel de Icaza <miguel@ximian.com>
2931 * expression.cs: Special case the `null' object when trying to
2932 auto-compute the type, as anything can be explicitly converted to
2935 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
2936 spotting this Paolo.
2938 (Expression.ImplicitNumericConversion): Perform comparissions of
2939 the type using the underlying type in the case of an enumeration
2940 rather than using the enumeration type for the compare.
2942 Cope with the underlying == type case, which is not possible to
2945 (Expression.ConvertNumericExplicit): Perform comparissions of
2946 the type using the underlying type in the case of an enumeration
2947 rather than using the enumeration type for the compare.
2949 * driver.cs: If the user does not supply an extension, assume .exe
2951 * cs-parser.jay (if_statement): Rewrote so that we can track the
2952 location for the if statement.
2954 * expression.cs (Binary.ConstantFold): Only concat strings when
2955 the operation is "+", not everything ;-)
2957 * statement.cs (Statement.EmitBoolExpression): Take a location
2959 (If, While, Do): Track location.
2961 * expression.cs (Binary.ResolveOperator): In the object + string
2962 case, I was missing a call to ConvertImplicit
2964 2002-02-25 Ravi Pratap <ravi@ximian.com>
2966 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
2967 Location arguments. Ensure we use RootContext.LookupType to do our work
2968 and not try to do a direct Type.GetType and ModuleBuilder.GetType
2970 * interface.cs (PopulateMethod): Handle the type of the parameter being
2973 * expression.cs (Invocation.BetterFunction): Handle the case when we
2974 have a params method with no fixed arguments and a call is made with no
2977 2002-02-25 Miguel de Icaza <miguel@ximian.com>

2980 the verbatim-string-literal
2982 * support.cs (InternalParameters.ParameterModifier): handle null
2984 (InternalParameters.ParameterType): ditto.
2986 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
2987 duplicating the name of the variable parameter.
2988 (GetParameterByName): Fix bug where we were not looking up array
2989 paramters if they were the only present (thanks Paolo!).
2990 (GetParameterInfo): We only have an empty set of types if both
2991 fixed and array are set to null.
2992 (GetParameterInfo-idx): Handle FixedParameter == null
2994 * cs-parser.jay: Handle the case where there is no catch
2995 statements (missing null test).
2997 2002-02-22 Miguel de Icaza <miguel@ximian.com>
2999 * driver.cs (MainDriver): Be conservative on our command line
3002 Catch DirectoryNotFoundException when calling GetFiles.
3004 (SplitPathAndPattern): Used to split the input specification into
3005 a path and a pattern that we can feed to Directory.GetFiles.
3007 2002-02-21 Miguel de Icaza <miguel@ximian.com>
3009 * statement.cs (Fixed): Implement the last case of the Fixed
3010 statement (string handling).
3012 * expression.cs (StringPtr): New class used to return a char * to
3013 a string; Used by the Fixed statement.
3015 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
3017 * expression.cs (Binary.ResolveOperator): Remove redundant
3018 MemberLookup pn parent type.
3019 Optimize union call, we do not need a union if the types are the same.
3020 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
3023 Specialize the use of MemberLookup everywhere, instead of using
3024 the default settings.
3026 (StackAlloc): Implement stackalloc keyword.
3028 * cs-parser.jay: Add rule to parse stackalloc.
3030 * driver.cs: Handle /h, /help, /?
3032 * expression.cs (MakeByteBlob): Removed the hacks we had in place
3033 before we supported unsafe code.
3035 * makefile: add --unsafe to the self compilation of mcs.
3037 2002-02-20 Miguel de Icaza <miguel@ximian.com>
3039 * expression.cs (PointerArithmetic): New class that is used to
3040 perform pointer arithmetic.
3041 (Binary.Resolve): Handle pointer arithmetic
3042 Handle pointer comparission.
3043 (ArrayPtr): Utility expression class that is used to take the
3044 address of an array.
3046 (ElementAccess): Implement array access for pointers
3048 * statement.cs (Fixed): Implement fixed statement for arrays, we
3049 are missing one more case before we are done.
3051 * expression.cs (Indirection): Implement EmitAssign and set the
3052 ExprClass to Variable. This allows pointer dereferences to be
3053 treated as variables, and to have values assigned to them.
3055 * ecore.cs (Expression.StoreFromPtr): New utility function to
3056 store values dereferencing.
3058 2002-02-20 Ravi Pratap <ravi@ximian.com>
3060 * expression.cs (Binary.ResolveOperator): Ensure that we are
3061 not trying to operate on a void type - this fixes the reported
3064 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
3065 the parent implementation is sealed.
3067 * ../errors/cs0239.cs : Add.
3069 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
3071 * typemanager.cs (unverifiable_code_type): Corresponds to
3072 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
3073 which have unsafe code in them.
3075 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
3078 2002-02-19 Miguel de Icaza <miguel@ximian.com>
3080 * cs-tokenizer.cs: Add support for @"litreal strings"
3082 Make tokenizer accept pre-processor directives
3083 on any column (remove the old C-like limitation).
3085 * rootcontext.cs (EmitCode): Emit any global attributes.
3086 (AddGlobalAttributes): Used to keep track of assembly attributes.
3088 * attribute.cs (ApplyAttributes): Support AssemblyAttributes.

3092 2002-02-17 Miguel de Icaza <miguel@ximian.com>
3094 * expression.cs (Indirection): New helper class. Unary will
3095 create Indirection classes to be able to implement the
3096 IMemoryLocation interface on it.
3098 2002-02-16 Miguel de Icaza <miguel@ximian.com>
3100 * cs-parser.jay (fixed_statement): reference the right statement.
3102 * statement.cs (Fixed.Emit): Finish implementing the fixed
3103 statement for the &x case.
3105 2002-02-14 Miguel de Icaza <miguel@ximian.com>
3107 * class.cs (Property.Define, Method.Define): Remove newslot when
3110 * modifiers.cs: My use of NewSlot when `Abstract' was set was
3111 wrong. NewSlot should only be used if the `new' keyword is present.
3113 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
3114 locating our system dir. Sorry about this.
3116 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3118 * driver.cs (GetSystemDir): Compute correctly the location of our
3119 system assemblies. I was using the compiler directory instead of
3120 the library directory.
3122 2002-02-13 Ravi Pratap <ravi@ximian.com>
3124 * expression.cs (BetterFunction): Put back in what Miguel commented out
3125 since it is the correct fix. The problem is elsewhere ;-)
3127 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
3128 parameters of the parms method are themselves compatible or not !
3130 (StandardConversionExists): Fix very dangerous bug where we were forgetting
3131 to check that a class implements an interface before saying that an implicit
3132 conversion was allowed. Use ImplementsInterface to do the checking.
3134 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3136 * class.cs (Method.Define): Track whether we are an explicit
3137 implementation or not. And only call DefineMethodOverride if we
3138 are an explicit implementation.
3140 (Property.DefineMethod): Ditto.
3142 2002-02-11 Ravi Pratap <ravi@ximian.com>
3144 * expression.cs (BetterFunction): Catch hideous bug which was
3145 preventing us from detecting ambiguous calls due to implicit casts i.e
3148 2002-01-29 Miguel de Icaza <miguel@ximian.com>
3150 * support.cs (Pair): Remove un-needed method. I figured why I was
3151 getting the error in cs-parser.jay, the variable in a foreach loop
3152 is readonly, and the compiler does not really treat this as a variable.
3154 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
3155 instead of EQUALS in grammar.
3157 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
3159 * expression.cs (Unary.DoResolve): Check whether the argument is
3162 2002-01-28 Miguel de Icaza <miguel@ximian.com>
3164 * support.cs: Api for Pair to set a value. Despite the fact that
3165 the variables are public the MS C# compiler refuses to compile
3166 code that accesses the field if the variable is part of a foreach
3169 * statement.cs (Fixed): Begin implementation of the fixed
3172 (Block.AddVariable): Return the VariableInfo on success and null
3173 on failure instead of true/false.
3175 * cs-parser.jay (foreach): Catch errors on variables already
3176 defined (we were ignoring this value before) and properly unwind
3179 (fixed_statement): grammar for the fixed statement.
3181 2002-01-25 Miguel de Icaza <miguel@ximian.com>
3183 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
3184 pointer types to be incretemented.
3186 (SizeOf): Implement.
3188 * cs-parser.jay (pointer_member_access): Implement
3189 expr->IDENTIFIER production.
3191 * expression.cs (IndexerAccess.DoResolve, ArrayAccess.DoResolve,
3192 MemberAccess.DoResolve, Invocation.DoResolve): Check for pointers
3195 (Unary): Implement indirection.
3197 * ecore.cs (Expression.UnsafeError): Reports error 214 (pointer
3198 use in non-unsafe context).
3200 (SimpleName.DoResolve): Check for pointers in field access on safe
3203 (Expression.LoadFromPtr): Factor the load-indirect code in this
3204 function. This was duplicated in UnboxCast and ParameterReference
3206 2002-01-24 Miguel de Icaza <miguel@ximian.com>
3208 * expression.cs (ComposedCast): report an error if a pointer cast
3209 is used in a safe region.
3211 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
3212 pointer type casts in unsafe context.
3214 * codegen.cs (EmitContext): Set up IsUnsafe.
3216 * cs-parser.jay (non_expression_type): Add productions for pointer
3219 * expression.cs (Invocation.EmitCall): Remove chunk of buggy
3220 code. We should not use force into static mode if the method is
3221 not virtual. Fixes bug in MIS
3223 * statement.cs (Do.Emit, While.Emit, For.Emit,
3224 Statement.EmitBoolExpression): Add support to Do and While to
3225 propagate infinite loop as `I do return' semantics.
3227 Improve the For case to also test for boolean constants.
3229 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
3230 to the list of attributes we can add.
3232 Remove `EmitContext' argument.
3234 * class.cs (Method.Define): Apply parameter attributes.
3235 (Constructor.Define): Apply parameter attributes.
3236 (MethodCore.LabelParameters): Move here the core of labeling
3239 * support.cs (ReflectionParameters.ParameterModifier,
3240 InternalParameters.ParameterModifier): Use IsByRef on the type and
3241 only return the OUT bit for these parameters instead of in/out/ref
3244 This is because I miss-understood things. The ParameterInfo.IsIn
3245 and IsOut represent whether the parameter has the [In] and [Out]
3248 2002-01-22 Miguel de Icaza <miguel@ximian.com>
3250 * ecore.cs (FieldExpr.Emit): Release temporaries.
3252 * assign.cs (LocalTemporary.Release): new function.
3254 * codegen.cs (EmitContext.GetTemporaryStorage,
3255 EmitContext.FreeTemporaryStorage): Rework the way we deal with
3256 temporary storage. Now we can "put back" localbuilders when we
3259 2002-01-21 Miguel de Icaza <miguel@ximian.com>
3261 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
3262 need to make a copy of the variable to generate verifiable code.
3264 2002-01-19 Miguel de Icaza <miguel@ximian.com>
3266 * driver.cs: Compute dynamically the system directory.
3268 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
3269 Slower, but more generally useful. Used by the abstract
3270 registering implementation.
3272 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
3273 the rules for the special rule on Type/instances. First check if
3274 we have the same name, and if so, try that special static path
3275 rather than the instance path.
3277 2002-01-18 Miguel de Icaza <miguel@ximian.com>
3279 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
3282 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
3283 Enum, ValueType, Delegate or Array for non-corlib compiles.
3285 * cs-tokenizer.cs: Catch long identifiers (645)
3287 * typemanager.cs (IndexerPropetyName): Ravi never tested this
3290 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
3291 fix, we were returning too early, so we were not registering
3292 pending methods from abstract classes.
3294 Do not register pending methods if the class is abstract.
3296 * expression.cs (Conditional.DoResolve): Report circular implicit
3297 conversions when we neecd to compute it for conditional
3300 (Is.DoResolve): If the expression is always of the provided type,
3301 flag warning 183. If the expression can not ever be of the
3302 provided type flag warning 184.
3304 * class.cs: Catch 169 as well.
3306 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
3309 2002-01-18 Nick Drochak <ndrochak@gol.com>
3311 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.
3313 2002-01-17 Miguel de Icaza <miguel@ximian.com>
3315 * interface.cs: (PopulateMethod): Check for pointers being defined
3316 only if the unsafe context is active.
3317 (PopulateProperty): ditto.
3318 (PopulateIndexer): ditto.
3320 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
3321 specified. If pointers are present, make sure that they are
3322 present in an unsafe context.
3323 (Constructor, Constructor.Define): ditto.
3324 (Field, Field.Define): ditto.
3325 (Property, Property.Define): ditto.
3326 (Event, Event.Define): ditto.
3328 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
3329 hashtable if there are classes or structs defined.
3331 * expression.cs (LocalVariableReference.DoResolve): Simplify this
3332 code, as the constant resolution moved.
3334 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
3335 the metadata, so we can flag error 133.
3337 * decl.cs (MemberCore.UnsafeOK): New function to test that a
3338 pointer is being declared in an unsafe context.
3340 2002-01-16 Miguel de Icaza <miguel@ximian.com>
3342 * modifiers.cs (Modifiers.Check): Require a Location argument.
3343 Report error 227 for Unsafe use.
3345 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
3347 * statement.cs (For.Emit): If the test is null, then report that
3348 we do `return', as we wont reach anything afterwards.
3350 (Switch.SwitchGoverningType): Track the expression that matched
3353 * driver.cs: Allow negative numbers as an error code to flag.
3355 * cs-parser.jay: Handle 1551.
3357 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
3359 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3361 * cs-parser.jay: Report 1518 (type declaration can only contain
3362 class, struct, interface, enum or delegate)
3364 (switch_label): Report 1523 (keywords `case' or `default' must
3367 (opt_switch_sections): Report 1522 (empty switch)
3369 * driver.cs: Report 1515 (response file specified multiple times)
3370 Report 1516 (Source file specified multiple times).
3372 * expression.cs (Argument.Resolve): Signal 1510
3374 (BaseAccess.Resolve, BaseIndexer.Resolve): Signal 1511 (base
3375 access not allowed in static code)
3377 2002-01-11 Ravi Pratap <ravi@ximian.com>
3379 * typemanager.cs (IsPointerType): Utility method which we are going
3382 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
3383 the object type, so we take care of that.
3385 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
3387 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
3388 added to non-params parameters :-)
3390 * typemanager.cs (CSharpName): Include 'void' type too.
3392 (void_ptr_type): Include in the set of core types.
3394 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
3397 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
3400 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
3401 completely forgotten about it.
3403 2002-01-10 Ravi Pratap <ravi@ximian.com>
3405 * cs-parser.jay (pointer_type): Add. This begins our implementation
3406 of parsing rules for unsafe code.
3408 (unsafe_statement): Implement.
3410 (embedded_statement): Modify to include the above.
3412 * statement.cs (Unsafe): Implement new class for unsafe blocks.
3414 * codegen.cs (EmitContext.InUnsafe): Add. This determines
3415 if the current context is an unsafe one.
3417 * cs-parser.jay (local_variable_pointer_type): Since local variable types
3418 are handled differently, we need separate rules for them.
3420 (local_variable_declaration): Update to use local_variable_pointer_type
3421 to allow variable declarations of unmanaged pointer types.
3423 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
3426 * ../errors/cs0214.cs : Add.
3428 2002-01-16 Nick Drochak <ndrochak@gol.com>
3430 * makefile: remove 'response' file when cleaning.
3432 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3434 * cs-parser.jay: Report 1524.
3436 2002-01-14 Miguel de Icaza <miguel@ximian.com>
3438 * typemanager.cs (RegisterMethod): drop checking if we have
3439 registered this from here
3441 2002-01-12 Miguel de Icaza <miguel@ximian.com>
3443 * class.cs (Method.EmitDestructor): Implement calling our base
3446 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
3449 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
3450 this routine and will wrap the call in a try/catch block. Deal
3453 2002-01-11 Miguel de Icaza <miguel@ximian.com>
3455 * ecore.cs (Expression.MemberLookup): instead of taking a
3456 parameter `same_type' that was used to tell whether we could
3457 access private members we compute our containing type from the
3460 (FieldExpr): Added partial support for volatile fields. This does
3461 not work for volatile fields exposed from assemblies, as I can not
3462 figure out how to extract the modreq from it.
3464 Updated all the source files to use this.
3466 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
3467 because it is referenced by MemberLookup very often.
3469 2002-01-09 Ravi Pratap <ravi@ximian.com>
3471 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
3472 TypeBuilder.GetCustomAttributes to retrieve what we need.
3474 Get rid of redundant default_member_attr_type as this is the same as
3475 default_member_type which already exists.
3477 * interface.cs, attribute.cs : Update accordingly.
3479 2002-01-08 Miguel de Icaza <miguel@ximian.com>
3481 * typemanager.cs: Enable IndexerPropertyName again. It does not
3482 work for TYpeBuilders though. Ravi, can you please fix this?
3484 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
3486 * expression.cs (Argument.Emit): Handle the case of ref objects
3487 being passed to ref functions;
3489 (ParameterReference.EmitLoad): Loads the content of the pointer
3490 without dereferencing.
3492 2002-01-07 Miguel de Icaza <miguel@ximian.com>
3494 * cs-tokenizer.cs: Implemented the pre-processing expressions.
3496 2002-01-08 Ravi Pratap <ravi@ximian.com>
3498 * class.cs (Indexer.DefineMethod): Incorporate the interface
3499 type in the name of the method if we are doing explicit interface
3502 * expression.cs (ConversionExists): Remove as it is completely obsolete.
3504 (BetterConversion): Fix extremely trivial bug where we were referring to
3505 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
3508 * ../errors/bug16.cs : Add although we have fixed it.
3510 2002-01-07 Miguel de Icaza <miguel@ximian.com>
3512 * expression.cs (BaseIndexer): Begin implementation.
3514 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
3516 * cs-parser.jay (indexer_declarator): Use qualified_identifier
3517 production directly to remove a shift/reduce, and implement
3518 explicit interface implementation.
3520 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
3521 after a floating point suffix.
3523 * expression.cs (DoNumericPromotions): Improved the conversion for
3524 uint/uint. If we have a constant, we avoid doing a typecast to a
3527 * class.cs (Indexer): Implement explicit interface implementation
3530 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
3532 * class.cs: make the default instance constructor public and hidebysig.
3534 2001-01-03 Ravi Pratap <ravi@ximian.com>
3536 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
3537 so we can call it from elsewhere.
3539 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
3540 we emit it internally if the class has a defined indexer; otherwise the user
3541 emits it by decorating the class definition with the DefaultMemberAttribute.
3543 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
3544 attribute is not used on a type which defines an indexer.
3546 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
3547 character when we skip whitespace.
3549 * ../errors/cs0646.cs : Add.
3551 2002-01-03 Miguel de Icaza <miguel@ximian.com>
3553 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
3556 * makefile: Add practical target `mcs3.exe' which builds the third
3557 generation compiler.
3559 * expression.cs (New): Fix structures constructor calling.
3561 * class.cs (Property, Method, Indexer): Emit Final flag on the
3562 method if we are an interface implementation and we are not
3565 * ecore.cs (PropertyExpr): New public field `IsBase', tells
3566 whether this property is referencing a `base' method.
3568 * expression.cs (Invocation.EmitCall): take an extra argument:
3569 is_base, this is used to determine whether the `call' or
3570 `callvirt' opcode should be used.
3573 * delegate.cs: update EmitCall.
3575 * class.cs (Method.Define): Set NewSlot for the cases where we are
3576 not implementing an interface method.
3578 (Property.Define): ditto.
3580 2002-01-02 Miguel de Icaza <miguel@ximian.com>
3582 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
3583 'r'. Allows mcs to parse itself fully.
3585 2002-01-02 Ravi Pratap <ravi@ximian.com>
3587 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
3588 of the number of initializers that require the InitializeArray method.
3590 (CheckIndices): Store the Expression in all cases - not the plain value. Also
3591 update the above field where necessary.
3593 (MakeByteBlob): Update accordingly.
3595 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
3598 (EmitDynamicInitializers): Update in accordance with the new optimization.
3600 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
3601 same OpCode applies.
3603 * cs-parser.jay : Fix some glaring errors I introduced.
3605 2002-01-01 Ravi Pratap <ravi@ximian.com>
3607 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
3608 so that we can check for name clashes there too.
3610 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
3611 for interface indexers.
3613 * interfaces.cs (Define): Emit the default member attribute.
3615 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
3616 variable was being referred to while setting the value ;-)
3618 2002-01-01 Miguel de Icaza <miguel@ximian.com>
3620 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
3621 byte-by-byte information when we know the data is zero.
3623 Make the block always a multiple of 4, because
3624 DefineInitializedData has a bug.
3626 * assign.cs: Fix, we should assign from the temporary, not from
3629 * expression.cs (MakeByteBlob): Fix my incorrect code.
3631 2001-12-31 Miguel de Icaza <miguel@ximian.com>
3633 * typemanager.cs (EnumToUnderlying): This function is used to get
3634 the underlying type from an enumeration, because it does not
3637 * constant.cs: Use the I4_S form for values between -128 and 127.
3639 * statement.cs (Block.LookupLabel): Looks up a label.
3640 (Block): Drop support for labeled blocks.
3642 (LabeledStatement): New kind of statement that represents a label
3645 (Goto): Finally implement this bad boy.
3647 * cs-parser.jay: Update to reflect new mechanism to implement
3650 2001-12-30 Miguel de Icaza <miguel@ximian.com>
3652 * codegen.cs (EmitContext.This): a codegen property that keeps the
3653 a single instance of this instead of creating many different this
3656 * delegate.cs (Delegate.DoResolve): Update to use the property;
3658 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
3660 * expression.cs (BaseAccess.DoResolve): Ditto.
3662 2001-12-29 Ravi Pratap <ravi@ximian.com>
3664 * typemanager.cs (methodimpl_attr_type): Add to hold the type
3665 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
3667 (InitCoreTypes): Update accordingly.
3669 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
3670 so we can quickly store the state.
3672 (ApplyAttributes): Set the correct implementation flags
3673 for InternalCall methods.
3675 2001-12-29 Miguel de Icaza <miguel@ximian.com>
3677 * expression.cs (EmitCall): if a method is not virtual, then do
3678 not use callvirt on it.
3680 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
3681 user defined stuff) requires the use of stobj, which takes an
3682 address on the stack instead of an array and an index. So emit
3683 the Ldelema operation for it.
3685 (EmitStoreOpcode): Use stobj for valuetypes.
3687 (UnaryMutator.EmitCode): Use the right 1 value depending on
3688 whether we are dealing with int64/uint64, float or doubles.
3690 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
3691 constructors that I implemented last night.
3693 (Constructor.IsDefault): Fix to work properly for static
3696 * cs-parser.jay (CheckDef): report method signature errors.
3697 Update error number 103 to be 132.
3699 * decl.cs: New AdditionResult enumeration value: MethodExists.
3700 Although we do this check for methods later on in the semantic
3701 analysis, catching repeated default constructors is so easy that
3702 we catch these here.
3704 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
3707 (ParameterReference.EmitAssign, Emit): handle
3710 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
3711 (ArrayAccess.EmitStoreOpcode): ditto.
3713 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
3715 * expression.cs (MakeByteBlob): Complete all the missing types
3716 (uint, short, ushort, byte, sbyte)
3718 * class.cs: Only init instance field initializers on instance
3721 Rename `constructors' to instance_constructors.
3723 (TypeContainer.AddConstructor): Only add constructors to the list
3724 if it is not static.
3726 Make sure that we handle default_static_constructor independently
3727 everywhere where we handle instance_constructors
3729 2001-12-28 Miguel de Icaza <miguel@ximian.com>
3731 * class.cs: Do not lookup or create a base initializer for a
3734 (ConstructorInitializer.Resolve): use the proper type to lookup
3737 * cs-parser.jay: Report error 1585 (modifiers between type and name).
3739 * enum.cs, interface.cs: Remove CloseType, this is taken care by
3742 * decl.cs: CloseType is now an virtual method, the default
3743 implementation just closes this type.
3745 2001-12-28 Ravi Pratap <ravi@ximian.com>
3747 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
3748 to PreserveSig by default. Also emit HideBySig on such methods.
3750 Basically, set the defaults to standard values.
3752 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
3753 argument, if candidate is better, it can't be worse than the best !
3755 (Invocation): Re-write bits to differentiate between methods being
3756 applicable in their expanded form and their normal form - for params
3759 Get rid of use_standard everywhere as only standard conversions are allowed
3760 in overload resolution.
3762 More spec conformance.
3764 2001-12-27 Miguel de Icaza <miguel@ximian.com>
3766 * driver.cs: Add --timestamp, to see where the compiler spends
3769 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
3770 `this' in static code.
3772 (SimpleName.DoResolve): Implement in terms of a helper function
3773 that allows static-references to be passed upstream to
3776 (Expression.ResolveWithSimpleName): Resolve specially simple
3777 names when called by MemberAccess to implement the special
3780 (Expression.ImplicitReferenceConversion): Handle conversions from
3781 Null to reference types before others, as Null's type is
3784 * expression.cs (Invocation.EmitCall): Handle the special case of
3785 calling methods declared on a reference type from a ValueType
3786 (Base classes System.Object and System.Enum)
3788 (MemberAccess.Resolve): Only perform lookups on Enumerations if
3789 the left hand side is a TypeExpr, not on every enumeration.
3791 (Binary.Resolve): If types are reference types, then do a cast to
3792 object on operators != and == of both arguments.
3794 * typemanager.cs (FindMembers): Extract instance and static
3795 members if requested.
3797 * interface.cs (PopulateProperty): Use void_type instead of null
3798 as the return type for the setter method.
3800 (PopulateIndexer): ditto.
3802 2001-12-27 Ravi Pratap <ravi@ximian.com>
3804 * support.cs (ReflectionParameters): Fix minor bug where we
3805 were examining the wrong parameter for the ParamArray attribute.
3807 Cope with requests for the type of the parameter at position
3808 greater than the params parameter's. We now return the element
3809 type of the params array as that makes more sense.
3811 * expression.cs (Invocation.IsParamsMethodApplicable): Update
3812 accordingly as we no longer have to extract the element type
3815 (Invocation.OverloadResolve): Update.
3817 2001-12-27 Miguel de Icaza <miguel@ximian.com>
3819 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
3820 against IEnumerator, test whether the return value is a descendant
3821 of the IEnumerator interface.
3823 * class.cs (Indexer.Define): Use an auxiliary method to implement
3824 the other bits of the method definition. Begin support for
3825 explicit interface implementation.
3827 (Property.DefineMethod): Use TypeManager.void_type instead of null
3828 for an empty return value.
3830 2001-12-26 Miguel de Icaza <miguel@ximian.com>
3832 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
3833 dealing with a FieldExpr which is composed of a FieldBuilder, in
3834 the code path we did extract the constant, but we should have
3835 obtained the underlying value to be able to cast it (otherwise we
3836 end up in an infinite loop, this is what Ravi was running into).
3838 (ArrayCreation.UpdateIndices): Arrays might be empty.
3840 (MemberAccess.ResolveMemberAccess): Add support for section
3841 14.5.4.1 that deals with the special case of E.I when E is a type
3842 and something else, that I can be a reference to a static member.
3844 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
3845 handle a particular array type to create byte blobs, it is just
3846 something we dont generate byteblobs for.
3848 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
3851 * location.cs (Push): remove the key from the hashtable that we
3852 are about to add. This happens for empty files.
3854 * driver.cs: Dispose files after we have parsed them.
3856 (tokenize): new function that only runs the tokenizer on its
3857 input, for speed testing.
3859 2001-12-26 Ravi Pratap <ravi@ximian.com>
3861 * class.cs (Event.Define): Define the private field only if there
3862 are no accessors defined.
3864 * expression.cs (ResolveMemberAccess): If there is no associated
3865 field with the event, that means we have an event defined with its
3866 own accessors and we should flag error cs0070 since transforming
3867 ourselves into a field is not valid in that case.
3869 * ecore.cs (SimpleName.DoResolve): Same as above.
3871 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
3872 and charset to sane values.
3874 2001-12-25 Ravi Pratap <ravi@ximian.com>
3876 * assign.cs (DoResolve): Perform check on events only if they
3877 are being accessed outside the declaring type.
3879 * cs-parser.jay (event_declarations): Update rules to correctly
3880 set the type of the implicit parameter etc.
3882 (add_accessor, remove_accessor): Set current local parameters.
3884 * expression.cs (Binary): For delegate addition and subtraction,
3885 cast the return value from the method into the appropriate delegate
3888 2001-12-24 Ravi Pratap <ravi@ximian.com>
3890 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
3891 of these as the workaround is unnecessary.
3893 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
3894 delegate data - none of that is needed at all.
3896 Re-write bits to extract the instance expression and the delegate method
3899 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
3902 * attribute.cs (ApplyAttributes): New method to take care of common tasks
3903 of attaching attributes instead of duplicating code everywhere.
3905 * everywhere : Update code to do attribute emission using the above method.
3907 2001-12-23 Miguel de Icaza <miguel@ximian.com>
3909 * expression.cs (IsParamsMethodApplicable): if there are not
3910 parameters, return immediately.
3912 * ecore.cs: The 0 literal can be implicity converted to an enum
3915 (SimpleName.DoResolve): First lookup the type, then lookup the
3918 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
3919 want to get its address. If the InstanceExpression is not
3920 addressable, store the result in a temporary variable, then get
3923 * codegen.cs: Only display 219 errors on warning level or above.
3925 * expression.cs (ArrayAccess): Make it implement the
3926 IMemoryLocation interface.
3928 (Binary.DoResolve): handle the operator == (object a, object b)
3929 and operator != (object a, object b) without incurring into a
3930 BoxedCast (because 5 != o should never be performed).
3932 Handle binary enumerator operators.
3934 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
3935 value type, otherwise use Ldelem_ref.
3937 Use precomputed names;
3939 (AddressOf): Implement address of
3941 * cs-parser.jay (labeled_statement): Fix recursive block
3942 addition by reworking the production.
3944 * expression.cs (New.DoEmit): New has a special case:
3946 If we are dealing with a ValueType, we have a few
3947 situations to deal with:
3949 * The target of New is a ValueType variable, that is
3950 easy, we just pass this as the variable reference
3952 * The target of New is being passed as an argument,
3953 to a boxing operation or a function that takes a
3956 In this case, we need to create a temporary variable
3957 that is the argument of New.
3960 2001-12-23 Ravi Pratap <ravi@ximian.com>
3962 * rootcontext.cs (LookupType): Check that current_type is not null before
3963 going about looking at nested types.
3965 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
3966 not implement the IAssignMethod interface any more.
3968 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
3969 where we tranform them into FieldExprs if they are being resolved from within
3972 * ecore.cs (SimpleName.DoResolve): Do the same here.
3974 * assign.cs (DoResolve, Emit): Clean up code considerably.
3976 * ../errors/bug10.cs : Add.
3978 * ../errors/cs0070.cs : Add.
3980 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
3982 * assign.cs : Get rid of EventIsLocal everywhere.
3984 2001-12-23 Miguel de Icaza <miguel@ximian.com>
3986 * ecore.cs (ConvertIntLiteral): finished the implementation.
3988 * statement.cs (SwitchLabel): Convert the value we are using as a
3989 key before looking up the table.
3991 2001-12-22 Miguel de Icaza <miguel@ximian.com>
3993 * codegen.cs (EmitTopBlock): Require a Location argument now.
3995 * cs-parser.jay (constructor_declarator): We need to setup
3996 current_local_parameters before we parse the
3997 opt_constructor_initializer, to allow the variables to be bound
3998 to the constructor arguments.
4000 * rootcontext.cs (LookupType): First lookup nested classes in our
4001 class and our parents before we go looking outside our class.
4003 * expression.cs (ConstantFold): Extract/debox the values at the
4006 * rootcontext.cs (EmitCode): Resolve the constants first before we
4007 resolve the types. This is not really needed, but it helps debugging.
4009 * statement.cs: report location.
4011 * cs-parser.jay: pass location to throw statement.
4013 * driver.cs: Small bug fix.
4015 * report.cs: Updated format to be 4-zero filled digits.
4017 2001-12-22 Ravi Pratap <ravi@ximian.com>
4019 * expression.cs (CheckIndices): Fix minor bug where the wrong
4020 variable was being referred to ;-)
4022 (DoEmit): Do not call EmitStaticInitializers when the
4023 underlying type is System.Object.
4025 2001-12-21 Ravi Pratap <ravi@ximian.com>
4027 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
4028 and do the usual workaround for SRE.
4030 * class.cs (MyEventBuilder.EventType): New member to get at the type
4031 of the event, quickly.
4033 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
4035 * assign.cs (Assign.DoResolve): Handle the case when the target
4036 is an EventExpr and perform the necessary checks.
4038 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
4041 (SimpleName.MemberStaticCheck): Include check for EventExpr.
4043 (EventExpr): Set the type in the constructor itself since we
4044 are meant to be born fully resolved.
4046 (EventExpr.Define): Revert code I wrote earlier.
4048 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
4049 instance expression is null. The instance expression is a This in that case
4050 or a null, depending on whether it is a static method or not.
4052 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
4053 refers to more than one method.
4055 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
4056 and accordingly flag errors.
4058 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4060 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
4062 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4064 * location.cs (ToString): Provide useful rutine.
4066 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4068 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
4069 objects, return the actual integral boxed.
4071 * statement.cs (SwitchLabel): define an ILLabel for each
4074 (Switch.CheckSwitch): If the value is a Literal, extract
4075 the underlying literal.
4077 Also in the unused hashtable we had, add the SwitchLabel so we can
4078 quickly look this value up.
4080 * constant.cs: Implement a bunch of new constants. Rewrite
4081 Literal based on this. Made changes everywhere to adapt to this.
4083 * expression.cs (Expression.MakeByteBlob): Optimize routine by
4084 dereferencing array only once, and also copes with enumrations.
4086 bytes are two bytes wide, not one.
4088 (Cast): Perform constant conversions.
4090 * ecore.cs (TryImplicitIntConversion): Return literals instead of
4091 wrappers to the literals here.
4093 * expression.cs (DoNumericPromotions): long literals can converted
4094 to ulong implicity (this is taken care of elsewhere, but I was
4097 * ecore.cs (Expression.Literalize): Make the return type Literal,
4098 to improve type checking.
4100 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
4102 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4104 * literal.cs: Revert code from ravi that checked the bounds. The
4105 bounds are sane by the definition of the type itself.
4107 * typemanager.cs: Fix implementation of ImplementsInterface. We
4108 need to actually look up in our parent hierarchy for interfaces
4111 * const.cs: Use the underlying type for enumerations
4113 * delegate.cs: Compute the basename for the delegate creation,
4114 that should fix the delegate test case, and restore the correct
4115 Type Lookup semantics in rootcontext
4117 * rootcontext.cs: Revert Ravi's last patch. The correct way of
4118 referencing a nested type with the Reflection API is using the "+"
4121 * cs-parser.jay: Do not require EOF token at the end.
4123 2001-12-20 Ravi Pratap <ravi@ximian.com>
4125 * rootcontext.cs (LookupType): Concatenate type names with
4126 a '.' instead of a '+' The test suite passes again.
4128 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
4129 field of the enumeration.
4131 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
4132 the case when the member is an EventExpr.
4134 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
4135 static has an associated instance expression.
4137 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
4139 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
4141 * class.cs (Event.Define): Register event and perform appropriate checks
4144 We define the Add and Remove methods even if the use provides none because
4145 in that case, we provide default implementations ourselves.
4147 Define a private field of the type of the event. This is done by the CSC compiler
4148 and we should be doing it too ;-)
4150 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
4151 More methods we use in code we generate.
4153 (multicast_delegate_type, delegate_type): Two separate types since the distinction
4156 (InitCoreTypes): Update accordingly for the above.
4158 * class.cs (Event.Emit): Generate code for default accessors that we provide
4160 (EmitDefaultMethod): Do the job in the above.
4162 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
4165 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4167 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
4168 builders even if we were missing one.
4170 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
4171 pass the Basename as our class name instead of the Name. The
4172 basename will be correctly composed for us.
4174 * parameter.cs (Paramters): Now takes a Location argument.
4176 * decl.cs (DeclSpace.LookupType): Removed convenience function and
4177 make all the code call directly LookupType in RootContext and take
4178 this chance to pass the Location information everywhere.
4180 * Everywhere: pass Location information.
4182 2001-12-19 Miguel de Icaza <miguel@ximian.com>
4184 * class.cs (Constructor.Define): Updated way of detecting the
4185 length of the parameters.
4187 (TypeContainer.DefineType): Use basename as the type name for
4190 (TypeContainer.Define): Do not recursively define types here, as
4191 definition is taken care in order by the RootContext.
4193 * tree.cs: Keep track of namespaces in a per-file basis.
4195 * parameter.cs (Parameter.ComputeSignature): Update to use
4198 (Parameters.GetSignature): ditto.
4200 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
4201 instead of a TypeContainer.
4203 (Interface.SemanticAnalysis): Use `this' instead of our parent to
4204 resolve names. Because we need to be resolve in our context, not
4207 * driver.cs: Implement response files.
4209 * class.cs (TypeContainer.DefineType): If we are defined, do not
4212 (Event.Emit): Emit the code for add/remove handlers.
4213 (Event.Define): Save the MethodBuilders for add/remove.
4215 * typemanager.cs: Use pair here too.
4217 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
4218 DictionaryEntry requires the first argument to be non-null.
4220 (enum_declaration): Compute full name for registering the
4223 (delegate_declaration): Instead of using
4224 formal_parameter_list, use opt_formal_parameter_list as the list
4227 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
4228 (EventParsing): New property that controls whether `add' and
4229 `remove' are returned as tokens or identifiers (for events);
4231 2001-12-19 Ravi Pratap <ravi@ximian.com>
4233 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
4234 use MyEventBuilder only and let it wrap the real builder for us.
4236 (MyEventBuilder): Revamp constructor etc.
4238 Implement all operations that we perform on EventBuilder in precisely the same
4241 (FindMembers): Update to use the EventBuilder member.
4243 (Event.Emit): Update accordingly.
4245 2001-12-18 Ravi Pratap <ravi@ximian.com>
4247 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
4248 by calling the appropriate methods.
4250 (GetCustomAttributes): Make stubs as they cannot possibly do anything
4253 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
4255 2001-12-17 Ravi Pratap <ravi@ximian.com>
4257 * delegate.cs (Delegate.Populate): Check that the return type
4258 and various parameters types are indeed accessible.
4260 * class.cs (Constructor.Define): Same here.
4262 (Field.Define): Ditto.
4264 (Event.Define): Ditto.
4266 (Operator.Define): Check that the underlying Method defined itself
4267 correctly - so it's MethodBuilder should not be null.
4269 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
4270 expression happens to be null.
4272 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
4273 members but as of now we don't seem to be able to do anything really useful with it.
4275 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
4276 not the EventBuilder.
4278 2001-12-18 Miguel de Icaza <miguel@ximian.com>
4280 * cs-tokenizer.cs: Add support for defines.
4281 Add support for #if, #elif, #else, #endif
4283 (eval_var): evaluates a variable.
4284 (eval): stubbed for evaluating functions.
4286 * cs-parser.jay: Pass the defines information
4288 * driver.cs: Add --define command line option.
4290 * decl.cs: Move MemberCore here.
4292 Make it the base class for DeclSpace. This allows us to catch and
4293 report 108 and 109 for everything now.
4295 * class.cs (TypeContainer.Define): Extract all the members
4296 before populating and emit the warning 108 (new keyword required
4297 to override) instead of having each member implement this.
4299 (MemberCore.Define): New abstract method, we will be using this in
4300 the warning reporting engine in Populate.
4302 (Operator.Define): Adjust to new MemberCore protocol.
4304 * const.cs (Const): This does not derive from Expression, it is a
4305 temporary object we use to create fields, it is a MemberCore.
4307 * class.cs (Method.Define): Allow the entry point to be in a
4310 * driver.cs: Rewrite the argument handler to clean it up a bit.
4312 * rootcontext.cs: Made it just an auxiliary namespace feature by
4313 making everything static.
4315 * driver.cs: Adapt code to use RootContext type name instead of
4318 * delegate.cs: Remove RootContext argument.
4320 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
4323 * class.cs (Event.Define): The lookup can fail.
4325 * cs-tokenizer.cs: Begin implementation of pre-procesor.
4327 * expression.cs: Resolve the this instance before invoking the code.
4329 2001-12-17 Miguel de Icaza <miguel@ximian.com>
4331 * cs-parser.jay: Add a production in element_access that allows
4332 the thing to become a "type" reference. This way we can parse
4333 things like "(string [])" as a type.
4335 Note that this still does not handle the more complex rules of
4339 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
4341 * ecore.cs: (CopyNewMethods): new utility function used to
4342 assemble the list of methods from running FindMembers.
4344 (MemberLookup): Rework FindMembers so that
4346 2001-12-16 Miguel de Icaza <miguel@ximian.com>
4348 * class.cs (TypeContainer): Remove Delegates who fail to be
4351 * delegate.cs (Populate): Verify that we dont get null return
4352 values. TODO: Check for AsAccessible.
4354 * cs-parser.jay: Use basename to emit error 574 (destructor should
4355 have the same name as container class), not the full name.
4357 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
4358 possible representation.
4360 Also implements integer type suffixes U and L.
4362 2001-12-15 Miguel de Icaza <miguel@ximian.com>
4364 * expression.cs (ArrayCreation.DoResolve): We need to do the
4365 argument resolution *always*.
4367 * decl.cs: Make this hold the namespace. Hold the root context as
4369 (LookupType): Move here.
4371 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
4373 * location.cs (Row, Name): Fixed the code, it was always returning
4374 references to the first file.
4376 * interface.cs: Register properties defined through interfaces.
4378 * driver.cs: Add support for globbing on the command line
4380 * class.cs (Field): Make it derive from MemberCore as well.
4383 2001-12-15 Ravi Pratap <ravi@ximian.com>
4385 * class.cs (Event::Define): Check that the type of the event is a delegate
4386 type else flag error #66.
4388 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
4391 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
4392 values of EntryPoint, CharSet etc etc.
4394 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
4396 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
4397 be null and we should ignore this. I am not sure if this is really clean. Apparently,
4398 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
4399 which needs this to do its work.
4401 * ../errors/cs0066.cs : Add.
4403 2001-12-14 Miguel de Icaza <miguel@ximian.com>
4405 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
4408 * class.cs: (MethodSignature.MethodSignature): Removed hack that
4409 clears out the parameters field.
4410 (MemberSignatureCompare): Cleanup
4412 (MemberCore): New base class used to share code between MethodCore
4415 (RegisterRequiredImplementations) BindingFlags.Public requires
4416 either BindingFlags.Instace or Static. Use instance here.
4418 (Property): Refactored code to cope better with the full spec.
4420 * parameter.cs (GetParameterInfo): Return an empty array instead
4423 * class.cs (Property): Abstract or extern properties have no bodies.
4425 * parameter.cs (GetParameterInfo): return a zero-sized array.
4427 * class.cs (TypeContainer.MethodModifiersValid): Move all the
4428 method modifier validation to the typecontainer so we can reuse
4431 (MethodCore.ParameterTypes): return an empty sized array of types.
4433 (Property.Define): Test property modifier validity.
4435 Add tests for sealed/override too.
4437 (Method.Emit): abstract or extern methods have no bodies.
4439 2001-12-14 Ravi Pratap <ravi@ximian.com>
4441 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
4444 (Method::Define, ::Emit): Modify accordingly.
4446 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
4448 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
4450 * makefile: Pass in /unsafe.
4452 2001-12-13 Miguel de Icaza <miguel@ximian.com>
4454 * class.cs (MakeKey): Kill routine.
4456 * class.cs (TypeContainer.Define): Correctly define explicit
4457 method implementations (they require the full interface name plus
4460 * typemanager.cs: Deply the PtrHashtable here and stop using the
4461 lame keys. Things work so much better.
4463 This of course broke everyone who depended on `RegisterMethod' to
4464 do the `test for existance' test. This has to be done elsewhere.
4466 * support.cs (PtrHashtable): A hashtable that avoid comparing with
4467 the object stupid Equals method (because, that like fails all over
4468 the place). We still do not use it.
4470 * class.cs (TypeContainer.SetRequiredInterface,
4471 TypeContainer.RequireMethods): Killed these two routines and moved
4472 all the functionality to RegisterRequiredImplementations.
4474 (TypeContainer.RegisterRequiredImplementations): This routine now
4475 registers all the implementations required in an array for the
4476 interfaces and abstract methods. We use an array of structures
4477 which can be computed ahead of time to reduce memory usage and we
4478 also assume that lookups are cheap as most classes will not
4479 implement too many interfaces.
4481 We also avoid creating too many MethodSignatures.
4483 (TypeContainer.IsInterfaceMethod): Update and optionally does not
4484 clear the "pending" bit if we find that there are problems with

4502 the TypeContainer. This code was buggy.
4504 * interface.cs: Full registation here.

4577 * statement.cs (Using.EmitLocalVariableDecls): Split the
4578 localvariable handling of the using statement.
4580 (Block.EmitMeta): Keep track of variable count across blocks. We
4581 were reusing slots on separate branches of blocks.
4583 (Try.Emit): Emit the general code block, we were not emitting it.
4585 Check the type of the declaration to be an IDisposable or
4586 something that can be implicity converted to it.

4609 properly generate the overflow opcodes.
4611 2001-12-04 Miguel de Icaza <miguel@ximian.com>
4613 * statement.cs: The correct type for the EmptyExpression is the
4614 element_type, not the variable type. Ravi pointed this out.
4616 2001-12-04 Ravi Pratap <ravi@ximian.com>
4618 * class.cs (Method::Define): Handle PInvoke methods specially
4619 by using DefinePInvokeMethod instead of the usual one.
4621 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
4622 above to do the task of extracting information and defining the method.
4624 2001-12-04 Ravi Pratap <ravi@ximian.com>

4711 * enum.cs (LookupEnumValue): Re-write various bits, return an object value
4712 instead of a Literal - much easier.
4714 (EnumInTransit): Remove - utterly useless :-)
4716 (Populate): Re-write bits - remove duplicate code etc. The code is much neater now.

4868 2001-11-22 Miguel de Icaza <miguel@ximian.com>
4870 * statement.cs (If.Emit): Fix a bug that generated incorrect code
4871 on If. Basically, we have to return `true' (ie, we do return to

4875 short-circuit operators, handle them as short circuit operators.

4878 (Cast.Cast): Take an expression as the target type.
4880 * cs-parser.jay (cast_expression): Remove old hack that only
4881 allowed a limited set of types to be handled. Now we take a
4882 unary_expression and we resolve to a type during semantic
4885 Use the grammar productions from Rhys to handle casts (this is
4886 not complete like Rhys syntax yet, we fail to handle that corner
4887 case that C# has regarding (-x), but we will get there.
4889 2001-11-22 Ravi Pratap <ravi@ximian.com>
4891 * class.cs (EmitFieldInitializer): Take care of the case when we have a
4892 field which is an array type.

4898 (everywhere): Use the above appropriately.
4900 * cs-parser.jay (for_statement): Update for array initialization while
4901 declaring variables.
4903 * ecore.cs : The error message was correct, it's the variable's names that

4906 (MemberAccess::DoResolve): Fix the code which handles Enum literals to set
4907 the correct type etc.
4909 (ConvertExplicit): Handle Enum types by examining the underlying type.
4911 2001-11-21 Ravi Pratap <ravi@ximian.com>

4924 BindingFlags.Instance as well
4926 * ecore.cs (Expression.TryImplicitIntConversion): Wrap the result
4927 implicit int literal conversion in an empty cast so that we
4928 propagate the right type upstream.
4930 (UnboxCast): new class used to unbox value types.
4931 (Expression.ConvertExplicit): Add explicit type conversions done
4934 (Expression.ImplicitNumericConversion): Oops, forgot to test for
4935 the target type before applying the implicit LongLiterals to ULong
4938 2001-11-21 Miguel de Icaza <miguel@ximian.com>
4940 * cs-parser.jay (for_statement): Reworked the way For works: now
4941 we declare manually any variables that are introduced in
4942 for_initializer to solve the problem of having out-of-band code
4943 emition (that is what got for broken).
4945 (declaration_statement): Perform the actual variable declaration
4946 that used to be done in local_variable_declaration here.
4948 (local_variable_declaration): Do not declare anything, just pass
4949 the information on a DictionaryEntry
4951 2001-11-20 Ravi Pratap <ravi@ximian.com>
4953 * expression.cs (ArrayCreation::CheckIndices): The story continues :-) Complete

5016 we can use this elsewhere.
5018 * statement.cs: Finish implementation of foreach for single
5021 * cs-parser.jay: Use an out-of-band stack to pass information
5022 around, I wonder why I need this.
5024 foreach_block: Make the new foreach_block the current_block.
5026 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
5027 function used to return a static Parameters structure. Used for
5028 empty parameters, as those are created very frequently.
5030 * cs-parser.jay, class.cs: Use GetEmptyReadOnlyParameters
5032 2001-11-15 Ravi Pratap <ravi@ximian.com>
5034 * interface.cs : Default modifier is private, not public. The
5035 make verify test passes again.
5037 2001-11-15 Ravi Pratap <ravi@ximian.com>
5039 * support.cs (ReflectionParameters): Fix logic to determine
5040 whether the last parameter is a params one. Test 9 passes again.

5046 of $$ to get at the location.
5048 (indexer_declaration): Similar stuff.
5052 * class.cs (Property): Register parameters for the Get and Set methods

5073 2001-11-09 Miguel de Icaza <miguel@ximian.com>
5075 * enum.cs (Enum.Emit): Delay the lookup of loc until we run into
5076 an error. This removes the lookup from the critical path.

5094 way we can report the error correctly for missing return values.
5096 * class.cs (Method.Emit): Clean up.
5098 * expression.cs (Argument.Resolve): Take another argument: the
5099 location where this argument is used. Notice that this is not
5100 part of the "Argument" class as to reduce the size of the
5101 structure (we know the approximate location anyways).
5103 Test if the argument is a variable-reference, if not, then
5104 complain with a 206.
5106 (Argument.Emit): Emit addresses of variables.
5108 (Argument.FullDesc): Simplify.
5110 (Invocation.DoResolve): Update for Argument.Resolve.
5112 (ElementAccess.DoResolve): ditto.

5135 2001-11-13 Miguel de Icaza <miguel@ximian.com>
5137 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
5138 enumerations that are used in heavily used structures derive from
5139 byte in a laughable and pathetic attempt to reduce memory usage.
5140 This is the kind of pre-optimzations that you should not do at
5141 home without adult supervision.
5143 * expression.cs (UnaryMutator): New class, used to handle ++ and
5144 -- separatedly from the other unary operators. Cleans up the
5145 code, and kills the ExpressionStatement dependency in Unary.
5147 (Unary): Removed `method' and `Arguments' from this class, making
5148 it smaller, and moving it all to SimpleCall, so I can reuse this
5149 code in other locations and avoid creating a lot of transient data
5150 strucutres when not required.
5152 * cs-parser.jay: Adjust for new changes.
5154 2001-11-11 Miguel de Icaza <miguel@ximian.com>
5156 * enum.cs (Enum.Populate): If there is a failure during
5159 * cs-parser.jay (opt_enum_base): we used to catch type errors

5165 * cs-parser.jay (operator_declarator, conversion_operator_declarator): Set

5900 (AddDelegateType): Implement.
5902 (IsDelegateType): Implement helper method.
5904 * delegate.cs (DefineDelegate): Use AddDelegateType instead of AddUserType.
5906 * expression.cs (New::DoResolve): Check if we are trying to instantiate a delegate type
5907 and accordingly handle it.
5909 * delegate.cs (Populate): Take TypeContainer argument.
5910 Implement bits to define the Invoke method. However, I still haven't figured out
5911 how to take care of the native int bit :-(
5913 * cs-parser.jay (delegate_declaration): Fixed the bug that I had introduced :-)
5914 Qualify the name of the delegate, not its return type !
5916 * expression.cs (ImplicitReferenceConversion): Implement guts of implicit array
5919 (StandardConversionExists): Checking for array types turns out to be recursive.
5921 (ConvertReferenceExplicit): Implement array conversion.
5923 (ExplicitReferenceConversionExists): New method to determine precisely that :-)
5925 2001-10-12 Ravi Pratap <ravi@ximian.com>
5927 * cs-parser.jay (delegate_declaration): Store the fully qualified
5928 name as it is a type declaration.
5930 * delegate.cs (ReturnType, Name): Rename members to these. Make them
5933 (DefineDelegate): Renamed from Define. Does the same thing essentially,
5934 as TypeContainer::DefineType.
5936 (Populate): Method in which all the definition of the various methods (Invoke)
5939 (Emit): Emit any code, if necessary. I am not sure about this really, but let's
5942 (CloseDelegate): Finally creates the delegate.
5944 * class.cs (TypeContainer::DefineType): Update to define delegates.
5945 (Populate, Emit and CloseType): Do the same thing here too.
5947 * rootcontext.cs (ResolveTree, PopulateTypes, EmitCode, CloseTypes): Include
5948 delegates in all these operations.
5950 2001-10-14 Miguel de Icaza <miguel@ximian.com>
5952 * expression.cs: LocalTemporary: a new expression used to
5953 reference a temporary that has been created.
5955 * assign.cs: Handle PropertyAccess back here, so that we can
5956 provide the proper semantic access to properties.
5958 * expression.cs (Expression::ConvertReferenceExplicit): Implement
5959 a few more explicit conversions.
5961 * modifiers.cs: `NEW' modifier maps to HideBySig.
5963 * expression.cs (PropertyExpr): Make this into an
5964 ExpressionStatement, and support the EmitStatement code path.
5966 Perform get/set error checking, clean up the interface.
5968 * assign.cs: recognize PropertyExprs as targets, and if so, turn
5969 them into toplevel access objects.

5973 * expression.cs: PropertyExpr::PropertyExpr: use work around the
5976 * typemanager.cs: Keep track here of our PropertyBuilders again to
5977 work around lameness in SRE.
5979 2001-10-11 Miguel de Icaza <miguel@ximian.com>
5981 * expression.cs (LValue::LValueResolve): New method in the
5982 interface, used to perform a second resolution pass for LValues.
5984 (This::DoResolve): Catch the use of this in static methods.
5986 (This::LValueResolve): Implement.
5988 (This::Store): Remove warning, assigning to `this' in structures
5991 (Invocation::Emit): Deal with invocation of
5992 methods on value types. We need to pass the address to structure
5993 methods rather than the object itself. (The equivalent code to
5994 emit "this" for structures leaves the entire structure on the
5995 stack instead of a pointer to it).
5997 (ParameterReference::DoResolve): Compute the real index for the
5998 argument based on whether the method takes or not a `this' pointer
5999 (ie, the method is static).
6001 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store
6002 value types returned from functions when we need to invoke a
6003 method on the sturcture.
6006 2001-10-11 Ravi Pratap <ravi@ximian.com>
6008 * class.cs (TypeContainer::DefineType): Method to actually do the business of
6009 defining the type in the Modulebuilder or Typebuilder. This is to take
6010 care of nested types which need to be defined on the TypeBuilder using
6013 (TypeContainer::GetClassBases): Implement. Essentially the code from the
6014 methods in RootContext, only ported to be part of TypeContainer.
6016 (TypeContainer::GetInterfaceOrClass): Ditto.
6018 (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
6020 * interface.cs (Interface::DefineInterface): New method. Does exactly
6021 what RootContext.CreateInterface did earlier, only it takes care of nested types
6024 (Interface::GetInterfaces): Move from RootContext here and port.
6026 (Interface::GetInterfaceByName): Same here.
6028 * rootcontext.cs (ResolveTree): Re-write.

6032 * class.cs (TypeContainer::Populate): Populate nested types too.
6033 (TypeContainer::Emit): Emit nested members too.
6035 * typemanager.cs (AddUserType): Do not make use of the FullName property,
6036 instead just use the name argument passed in as it is already fully
6039 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
6040 to TypeContainer mapping to see if a type is user-defined.
6042 * class.cs (TypeContainer::CloseType): Implement.
6044 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
6045 the default constructor.
6047 (TypeContainer::Populate): Fix minor bug which led to creating default constructors
6050 (Constructor::IsDefault): Fix up logic to determine if it is the default constructor
6052 * interface.cs (CloseType): Create the type here.
6054 * rootcontext.cs (CloseTypes): Re-write to recursively close types by running through
6057 Remove all the methods which are now in TypeContainer.
6059 2001-10-10 Ravi Pratap <ravi@ximian.com>
6061 * delegate.cs (Define): Re-write bits to define the delegate
6064 2001-10-10 Miguel de Icaza <miguel@ximian.com>
6066 * makefile: Renamed the compiler to `mcs.exe' instead of compiler.exe
6068 * expression.cs (ImplicitReferenceConversion): handle null as well
6069 as a source to convert to any reference type.
6071 * statement.cs (Return): Perform any implicit conversions to
6072 expected return type.
6074 Validate use of return statement.
6076 * codegen.cs (EmitContext): Pass the expected return type here.
6078 * class.cs (Method, Constructor, Property): Pass expected return
6079 type to EmitContext.
6081 2001-10-09 Miguel de Icaza <miguel@ximian.com>
6083 * expression.cs: Make DoResolve take an EmitContext instead of a
6086 Replaced `l' and `location' for `loc', for consistency.
6088 (Error, Warning): Remove unneeded Tc argument.
6090 * assign.cs, literal.cs, constant.cs: Update to new calling
6093 * codegen.cs: EmitContext now contains a flag indicating whether
6094 code is being generated in a static method or not.
6096 * cs-parser.jay: DecomposeQI, new function that replaces the old
6097 QualifiedIdentifier. Now we always decompose the assembled
6098 strings from qualified_identifier productions into a group of
6101 2001-10-08 Miguel de Icaza <miguel@ximian.com>
6103 * rootcontext.cs: Deal with field-less struct types correctly now
6104 by passing the size option to Define Type.
6106 * class.cs: Removed hack that created one static field.
6108 2001-10-07 Miguel de Icaza <miguel@ximian.com>
6110 * statement.cs: Moved most of the code generation here.
6112 2001-10-09 Ravi Pratap <ravi@ximian.com>
6114 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
6117 (ElementAccess): Remove useless bits for now - keep checks as the spec
6120 2001-10-08 Ravi Pratap <ravi@ximian.com>
6122 * expression.cs (ElementAccess::DoResolve): Remove my crap code
6123 and start performing checks according to the spec.
6125 2001-10-07 Ravi Pratap <ravi@ximian.com>
6127 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
6128 rank_specifiers instead.
6130 (rank_specifiers): Change the order in which the rank specifiers are stored
6132 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
6134 * expression.cs (ElementAccess): Implement the LValue interface too.
6136 2001-10-06 Ravi Pratap <ravi@ximian.com>
6138 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
6139 except that user defined conversions are not included.
6141 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
6142 perform the conversion of the return type, if necessary.
6144 (New::DoResolve): Check whether we are creating an array or an object
6145 and accordingly do the needful.
6147 (New::Emit): Same here.
6149 (New::DoResolve): Implement guts of array creation.
6151 (New::FormLookupType): Helper function.
6153 2001-10-07 Miguel de Icaza <miguel@ximian.com>
6155 * codegen.cs: Removed most of the code generation here, and move the
6156 corresponding code generation bits to the statement classes.
6158 Added support for try/catch/finalize and throw.
6160 * cs-parser.jay: Added support for try/catch/finalize.
6162 * class.cs: Catch static methods having the flags override,
6163 virtual or abstract.
6165 * expression.cs (UserCast): This user cast was not really doing
6166 what it was supposed to do. Which is to be born in fully resolved
6167 state. Parts of the resolution were being performed at Emit time!
6171 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6173 * expression.cs: Implicity convert the result from UserCast.
6175 2001-10-05 Ravi Pratap <ravi@ximian.com>
6177 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
6178 prevented it from working correctly.
6180 (ConvertExplicit): Make the first try, a call to ConvertImplicitStandard, not
6181 merely ConvertImplicit.
6183 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6185 * typemanager.cs: Make the LookupTypeContainer function static,
6186 and not per-instance.
6188 * class.cs: Make static FindMembers (the one that takes a Type
6191 * codegen.cs: Add EmitForeach here.
6193 * cs-parser.jay: Make foreach a toplevel object instead of the
6194 inline expansion, as we need to perform semantic analysis on it.
6196 2001-10-05 Ravi Pratap <ravi@ximian.com>
6198 * expression.cs (Expression::ImplicitUserConversion): Rename to
6199 UserDefinedConversion.
6201 (Expression::UserDefinedConversion): Take an extra argument specifying
6202 whether we look for explicit user conversions too.
6204 (Expression::ImplicitUserConversion): Make it a call to UserDefinedConversion.

6213 * expression.cs (Cast): Record location info.
6215 (Expression::ConvertExplicit): Take location argument.
6217 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
6218 to determine if we are doing explicit conversions.
6220 (UserCast::Emit): Update accordingly.
6222 (Expression::ConvertExplicit): Report an error if everything fails.
6224 * ../errors/cs0030.cs : Add.
6226 2001-10-04 Miguel de Icaza <miguel@ximian.com>
6228 * modifiers.cs: If the ABSTRACT keyword is present, also set the
6229 virtual and newslot bits.
6231 * class.cs (TypeContainer::RegisterRequiredImplementations):
6232 Record methods we need.
6234 (TypeContainer::MakeKey): Helper function to make keys for
6235 MethodBases, since the Methodbase key is useless.
6237 (TypeContainer::Populate): Call RegisterRequiredImplementations
6238 before defining the methods.
6240 Create a mapping for method_builders_to_methods ahead of time
6241 instead of inside a tight loop.
6243 (::RequireMethods): Accept an object as the data to set into the
6244 hashtable so we can report interface vs abstract method mismatch.
6246 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6248 * report.cs: Make all of it static.
6250 * rootcontext.cs: Drop object_type and value_type computations, as
6251 we have those in the TypeManager anyways.
6253 Drop report instance variable too, now it is a global.
6255 * driver.cs: Use try/catch on command line handling.
6257 Add --probe option to debug the error reporting system with a test
6260 * report.cs: Add support for exiting program when a probe
6261 condition is reached.
6263 2001-10-03 Ravi Pratap <ravi@ximian.com>
6265 * expression.cs (Binary::DoNumericPromotions): Fix the case when
6266 we do a forcible conversion regardless of type, to check if
6267 ForceConversion returns a null.
6269 (Binary::error19): Use location to report error.
6271 (Unary::error23): Use location here too.
6273 * ../errors/cs0019.cs : Check in.
6275 * ../errors/cs0023.cs : Check in.
6277 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
6278 case of a non-null MethodInfo object with a length of 0 !
6280 (Binary::ResolveOperator): Flag error if overload resolution fails to find
6281 an applicable member - according to the spec :-)
6282 Also fix logic to find members in base types.
6284 (Unary::ResolveOperator): Same here.
6286 (Unary::report23): Change name to error23 and make first argument a TypeContainer
6287 as I was getting thoroughly confused between this and error19 :-)
6289 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
6290 (::FindMostEncompassedType): Implement.
6291 (::FindMostEncompassingType): Implement.
6292 (::StandardConversionExists): Implement.
6294 (UserImplicitCast): Re-vamp. We now need info about most specific
6295 source and target types so that we can do the necessary conversions.
6297 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
6298 mathematical union with no duplicates.
6300 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6302 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
6303 in order from base classes to child classes, so that we can in
6304 child classes look up in our parent for method names and
6305 attributes (required for handling abstract, virtual, new, override
6306 constructs: we need to instrospect our base class, and if we dont
6307 populate the classes in order, the introspection might be
6308 incorrect. For example, a method could query its parent before
6309 the parent has any methods and would determine that the parent has
6310 no abstract methods (while it could have had them)).
6312 (RootContext::CreateType): Record the order in which we define the
6315 2001-10-02 Miguel de Icaza <miguel@ximian.com>
6317 * class.cs (TypeContainer::Populate): Also method definitions can
6318 fail now, keep track of this.
6320 (TypeContainer::FindMembers): Implement support for
6321 DeclaredOnly/noDeclaredOnly flag.
6323 (Constructor::Emit) Return the ConstructorBuilder.
6325 (Method::Emit) Return the MethodBuilder.
6326 Check for abstract or virtual methods to be public.
6328 * rootcontext.cs (RootContext::CreateType): Register all the
6329 abstract methods required for the class to be complete and the
6330 interface methods that must be implemented.
6332 * cs-parser.jay: Report error 501 (method requires body if it is
6333 not marked abstract or extern).
6335 * expression.cs (TypeOf::Emit): Implement.
6337 * typemanager.cs: runtime_handle_type, new global type.
6339 * class.cs (Property::Emit): Generate code for properties.
6341 2001-10-02 Ravi Pratap <ravi@ximian.com>
6343 * expression.cs (Unary::ResolveOperator): Find operators on base type
6344 too - we now conform exactly to the spec.
6346 (Binary::ResolveOperator): Same here.
6348 * class.cs (Operator::Define): Fix minor quirk in the tests.
6350 * ../errors/cs0215.cs : Added.
6352 * ../errors/cs0556.cs : Added.
6354 * ../errors/cs0555.cs : Added.
6356 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6358 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
6359 single integer which is really efficient
6361 2001-10-01 Ravi Pratap <ravi@ximian.com>
6363 * expression.cs (Expression::ImplicitUserConversion): Use location
6364 even in the case when we are examining True operators.
6366 * class.cs (Operator::Define): Perform extensive checks to conform
6367 with the rules for operator overloading in the spec.
6369 * expression.cs (Expression::ImplicitReferenceConversion): Implement
6370 some of the other conversions mentioned in the spec.
6372 * typemanager.cs (array_type): New static member for the System.Array built-in
6375 (cloneable_interface): For System.ICloneable interface.
6377 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
6378 we start resolving the tree and populating types.
6380 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
6382 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6384 * expression.cs (Expression::ExprClassFromMemberInfo,
6385 Expression::Literalize): Create literal expressions from
6386 FieldInfos which are literals.
6388 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
6389 type casts, because they were wrong. The test suite in tests
6392 (ImplicitNumericConversion): ushort to ulong requires a widening
6395 Int32 constant to long requires widening cast as well.
6397 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
6398 for integers because the type on the stack is not i4.
6400 2001-09-30 Miguel de Icaza <miguel@ximian.com>
6402 * expression.cs (report118): require location argument.
6404 * parameter.cs: Do not dereference potential null value.
6406 * class.cs: Catch methods that lack the `new' keyword when
6407 overriding a name. Report warnings when `new' is used without
6408 anything being there to override.
6410 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
6412 * class.cs: Only add constructor to hashtable if it is non-null
6413 (as now constructors can fail on define).
6415 (TypeManager, Class, Struct): Take location arguments.
6417 Catch field instance initialization in structs as errors.
6419 accepting_filter: a new filter for FindMembers that is static so
6420 that we dont create an instance per invocation.
6422 (Constructor::Define): Catch errors where a struct constructor is
6425 * cs-parser.jay: Pass location information for various new
6428 * delegate.cs (Delegate): take a location argument.
6430 * driver.cs: Do not call EmitCode if there were problesm in the
6431 Definition of the types, as many Builders wont be there.
6433 * decl.cs (Decl::Decl): Require a location argument.
6435 * cs-tokenizer.cs: Handle properly hex constants that can not fit
6436 into integers, and find the most appropiate integer for it.
6438 * literal.cs: Implement ULongLiteral.
6440 * rootcontext.cs: Provide better information about the location of
6441 failure when CreateType fails.
6443 2001-09-29 Miguel de Icaza <miguel@ximian.com>
6445 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
6448 * expression.cs (Binary::CheckShiftArguments): Add missing type
6450 (Binary::ResolveOperator): Add type to the logical and and logical
6451 or, Bitwise And/Or and Exclusive Or code paths, it was missing
6454 (Binary::DoNumericPromotions): In the case where either argument
6455 is ulong (and most signed types combined with ulong cause an
6456 error) perform implicit integer constant conversions as well.
6458 2001-09-28 Miguel de Icaza <miguel@ximian.com>
6460 * expression.cs (UserImplicitCast): Method should always be
6462 (Invocation::BetterConversion): Simplified test for IntLiteral.
6464 (Expression::ImplicitNumericConversion): Split this routine out.
6465 Put the code that performs implicit constant integer conversions
6468 (Expression::Resolve): Become a wrapper around DoResolve so we can
6469 check eclass and type being set after resolve.
6471 (Invocation::Badness): Remove this dead function
6473 (Binary::ResolveOperator): Do not compute the expensive argumnets
6474 unless we have a union for it.
6476 (Probe::Emit): Is needs to do an isinst and then
6477 compare against null.
6479 (::CanConvert): Added Location argument. If the Location argument
6480 is null (Location.Null), then we do not report errors. This is
6481 used by the `probe' mechanism of the Explicit conversion. We do
6482 not want to generate an error for something that the user
6483 explicitly requested to be casted. But the pipeline for an
6484 explicit cast first tests for potential implicit casts.
6486 So for now, if the Location is null, it means `Probe only' to
6487 avoid adding another argument. Might have to revise this
6490 (ClassCast): New class used to type cast objects into arbitrary
6491 classes (used in Explicit Reference Conversions).
6493 Implement `as' as well.
6495 Reverted all the patches from Ravi below: they were broken:
6497 * The use of `level' as a mechanism to stop recursive
6498 invocations is wrong. That was there just to catch the
6499 bug with a strack trace but not as a way of addressing
6502 To fix the problem we have to *understand* what is going
6503 on and the interactions and come up with a plan, not
6504 just get things going.
6506 * The use of the type conversion cache that I proposed
6507 last night had an open topic: How does this work across
6508 protection domains. A user defined conversion might not
6509 be public in the location where we are applying the
6510 conversion, a different conversion might be selected
6511 (ie, private A->B (better) but public B->A (worse),
6512 inside A, A->B applies, but outside it, B->A will
6515 * On top of that (ie, even if the above is solved),
6516 conversions in a cache need to be abstract. Ie, `To
6517 convert from an Int to a Short use an OpcodeCast', not
6518 `To convert from an Int to a Short use the OpcodeCast on
6519 the variable 5' (which is what this patch was doing).
6521 2001-09-28 Ravi Pratap <ravi@ximian.com>
6523 * expression.cs (Invocation::ConversionExists): Re-write to use
6524 the conversion cache
6526 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
6527 cache all conversions done, not just user-defined ones.
6529 (Invocation::BetterConversion): The real culprit. Use ConversionExists
6530 to determine if a conversion exists instead of acutually trying to
6531 perform the conversion. It's faster too.
6533 (Expression::ConvertExplicit): Modify to use ConversionExists to check
6534 and only then attempt the implicit conversion.
6536 2001-09-28 Ravi Pratap <ravi@ximian.com>
6538 * expression.cs (ConvertImplicit): Use a cache for conversions
6539 already found. Check level of recursion and bail out if necessary.
6541 2001-09-28 Miguel de Icaza <miguel@ximian.com>
6543 * typemanager.cs (string_concat_string_string, string_concat_object_object):
6544 Export standard methods that we expect for string operations.
6546 * statement.cs (Block::UsageWarning): Track usage of variables and
6547 report the errors for not used variables.
6549 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
6552 2001-09-27 Miguel de Icaza <miguel@ximian.com>
6554 * codegen.cs: remove unnneded code
6556 * expression.cs: Removed BuiltinTypeAccess class
6558 Fix the order in which implicit conversions are
6561 The previous fixed dropped support for boxed conversions (adding a
6562 test to the test suite now)
6564 (UserImplicitCast::CanConvert): Remove test for source being null,
6565 that code is broken. We should not feed a null to begin with, if
6566 we do, then we should track the bug where the problem originates
6567 and not try to cover it up here.
6569 Return a resolved expression of type UserImplicitCast on success
6570 rather than true/false. Ravi: this is what I was talking about,
6571 the pattern is to use a static method as a "constructor" for
6574 Also, do not create arguments until the very last minute,
6575 otherwise we always create the arguments even for lookups that
6576 will never be performed.
6578 (UserImplicitCast::Resolve): Eliminate, objects of type
6579 UserImplicitCast are born in a fully resolved state.
6581 * typemanager.cs (InitCoreTypes): Init also value_type
6584 * expression.cs (Cast::Resolve): First resolve the child expression.
6586 (LValue): Add new method AddressOf to be used by
6589 Change the argument of Store to take an EmitContext instead of an
6590 ILGenerator, because things like FieldExpr need to be able to call
6591 their children expression to generate the instance code.
6593 (Expression::Error, Expression::Warning): Sugar functions for
6596 (Expression::MemberLookup): Accept a TypeContainer instead of a
6597 Report as the first argument.
6599 (Expression::ResolvePrimary): Killed. I still want to improve
6600 this as currently the code is just not right.
6602 (Expression::ResolveMemberAccess): Simplify, but it is still
6605 (Unary::Resolve): Catch errors in AddressOf operators.
6607 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
6608 index to a byte for the short-version, or the compiler will choose
6609 the wrong Emit call, which generates the wrong data.

6615 * typemanager.cs: TypeManager: made public variable instead of
6618 * driver.cs: document --fatal.

6621 Error and Warning classes.
6623 * cs-parser.jay (member_access): Turn built-in access to types
6624 into a normal simplename
6626 2001-09-27 Ravi Pratap <ravi@ximian.com>

6629 with q being null, since this was introducing a bug.
6631 * expression.cs (ConvertImplicit): Do built-in conversions first.
6633 2001-09-27 Ravi Pratap <ravi@ximian.com>
6635 * expression.cs (UserImplicitCast::Resolve): Fix bug.
6637 2001-09-27 Ravi Pratap <ravi@ximian.com>
6639 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug

6642 * expression.cs (UserImplicitCast::CanConvert): Static method to do
6643 the work of all the checking.
6644 (ConvertImplicit): Call CanConvert and only then create object if necessary.

6647 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
6648 that is the right way.
6650 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
6651 overloading resolution. Use everywhere instead of cutting and pasting code.
6653 (Binary::ResolveOperator): Use MakeUnionSet.
6655 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
6656 we have to convert to bool types. Not complete yet.
6658 2001-09-27 Miguel de Icaza <miguel@ximian.com>
6660 * typemanager.cs (TypeManager::CSharpName): support ushort.
6662 * expression.cs (Expression::TryImplicitIntConversion): Attempts
6663 to provide an expression that performsn an implicit constant int
6664 conversion (section 6.1.6).
6665 (Expression::ConvertImplicitRequired): Reworked to include
6666 implicit constant expression conversions.
6668 (Expression::ConvertNumericExplicit): Finished.
6670 (Invocation::Emit): If InstanceExpression is null, then it means
6671 that we perform a call on this.
6673 2001-09-26 Miguel de Icaza <miguel@ximian.com>
6675 * expression.cs (Unary::Emit): Remove some dead code.
6676 (Probe): Implement Resolve and Emit for `is'.
6677 (Expression::ConvertImplicitRequired): Attempt to do constant
6678 expression conversions here. Maybe should be moved to
6679 ConvertImplicit, but I am not sure.
6680 (Expression::ImplicitLongConstantConversionPossible,
6681 Expression::ImplicitIntConstantConversionPossible): New functions
6682 that tell whether is it possible to apply an implicit constant
6683 expression conversion.

6696 ones that the spec expects (as we are just stringizing the
6699 * expression.cs (Unary::ResolveOperator): Fix bug: Use
6700 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
6701 previous usage did only work for our methods.
6702 (Expression::ConvertImplicit): Handle decimal implicit numeric
6703 conversions as well.
6704 (Expression::InternalTypeConstructor): Used to invoke constructors
6705 on internal types for default promotions.
6707 (Unary::Emit): Implement special handling for the pre/post
6708 increment/decrement for overloaded operators, as they need to have
6709 the same semantics as the other operators.
6711 (Binary::ResolveOperator): ditto.
6712 (Invocation::ConversionExists): ditto.
6713 (UserImplicitCast::Resolve): ditto.
6715 2001-09-26 Ravi Pratap <ravi@ximian.com>
6717 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded

6732 expressions that can appear in statements, so that we can provide
6733 an alternate path to generate expression that do not leave a value
6736 (Expression::Emit, and all the derivatives): We no longer return
6737 whether a value is left on the stack or not. Every expression
6738 after being emitted leaves a single value on the stack.

6741 facilties of ExpressionStatement if possible.
6743 * cs-parser.jay: Update statement_expression.

6768 * assign.cs: track location.
6769 (Resolve): Use implicit conversions on assignment.

6812 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
6813 Also take an additional TypeContainer argument.
6815 * All over : Pass in TypeContainer as argument to OverloadResolve.
6817 * typemanager.cs (CSharpName): Update to check for the string type and return

6834 * typemanager.cs: declare and load enum_type, delegate_type and
6837 * expression.cs (Expression::Emit): Now emit returns a value that
6838 tells whether a value is left on the stack or not. This strategy
6839 might be reveted tomorrow with a mechanism that would address
6840 multiple assignments.
6841 (Expression::report118): Utility routine to report mismatches on
6844 (Unary::Report23): Report impossible type/operator combination
6847 (Unary::IsIncrementableNumber): Whether the type can be

6892 * expression.cs: Instead of having FIXMEs in the Resolve
6893 functions, throw exceptions so it is obvious that we are facing a

6898 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
6899 Use a basename for those routines because .NET does not like paths

6911 * expression.cs (Unary::ResolveOperator): return the child
6912 expression for expressions which are just +expr.
6913 (Unary::ResolveOperator): Return negative literals for -LITERAL
6914 expressions (otherwise they are Unary {Literal}).
6915 (Invocation::Badness): Take into account `Implicit constant
6916 expression conversions'.
6918 * literal.cs (LongLiteral): Implement long literal class.
6919 (IntLiteral): export the `Value' of the intliteral.
6921 2001-09-19 Ravi Pratap <ravi@ximian.com>

6936 * expression.cs (Unary::Resolve): Implement.
6937 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
6938 operators are found instead of making noise ;-)
6939 (Unary::ResolveOperator): New method to do precisely the same thing which
6940 Binary::ResolveOperator does for Binary expressions.
6941 (Unary.method, .Arguments): Add.
6942 (Unary::OperName): Implement.
6943 (Unary::ForceConversion): Copy and Paste !
6945 * class.cs (Operator::Define): Fix a small bug for the case when we have
6948 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
6949 for the inbuilt operators. Only overloading works for now ;-)
6951 2001-09-18 Miguel de Icaza <miguel@ximian.com>
6953 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
6954 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

6967 (FieldExpr::Emit): Implement.
6969 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
6970 the last instruction contains a return opcode to avoid generating
6971 the last `ret' instruction (this generates correct code, and it is
6972 nice to pass the peverify output).
6974 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
6975 initializer for static and instance variables.
6976 (Constructor::Emit): Allow initializer to be null in the case of
6977 static constructors. Only emit initializer for instance
6980 (TypeContainer::FindMembers): Return a null array if there are no
6983 Also fix the code for the MemberTypes.Method branch, as it was not
6984 scanning that for operators (or tried to access null variables before).
6986 * assign.cs (Assign::Emit): Handle instance and static fields.
6990 * driver.cs: Stop compilation if there are parse errors.
6992 * cs-parser.jay (constructor_declaration): Provide default base

6995 initializers if none was specified.
6996 Catch the fact that constructors should not have parameters.
6998 * class.cs: Do not emit parent class initializers for static
6999 constructors, that should be flagged as an error.
7001 2001-09-18 Ravi Pratap <ravi@ximian.com>
7003 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
7004 Move back code into TypeContainer::Populate.

7030 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
7033 (Expression::MemberLookup): Provide a version that allows to
7034 specify the MemberTypes and BindingFlags.
7036 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
7037 so it was not fetching variable information from outer blocks.
7039 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
7040 Beforefieldinit as it was buggy.
7042 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
7045 * class.cs (Constructor::Emit): Only emit if block is not null.
7046 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
7047 deal with this by semantically definining it as if the user had
7050 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
7051 constructors as we now "emit" them at a higher level.

7054 default constructors if none was provided.
7056 (ConstructorInitializer): Add methods Resolve and Emit.
7058 * expression.cs: Cast to ConstructorInfo instead of MethodInfo

7077 * class.cs (Operator::OpType): Change names to match the ones in Binary::Operator
7078 and Unary::Operator.
7080 * cs-parser.jay (operator_declaration, CheckBinaryOperator, CheckUnaryOperator): Update
7083 * expression.cs (Binary::method): New member to hold the MethodBase for the case when
7084 we have overloaded operators.
7085 (Binary::ResolveOperator): Implement the part which does the operator overload
7088 * class.cs (Operator::Emit): Implement.
7089 (TypeContainer::Emit): Emit the operators we have too.
7091 * expression.cs (Binary::Emit): Update to emit the appropriate code for
7092 the case when we have a user-defined operator.
7094 2001-09-17 Miguel de Icaza <miguel@ximian.com>
7096 * rootcontext.cs: Fix bug: tree.Namespaces might be null.
7098 2001-09-16 Ravi Pratap <ravi@ximian.com>
7100 * class.cs (EmitStaticFieldInitializers, EmitFieldInitializers): Make public.
7101 (TypeContainer::EmitConstructor): Remove and move code into Contructor::Emit.

7124 * rootcontext.cs (IsNamespace): Fixed it :-)
7126 2001-09-14 Miguel de Icaza <miguel@ximian.com>
7128 * class.cs (TypeContainer::FindMembers): Add support for
7130 (MethodCore): New class that encapsulates both the shared aspects
7131 of a Constructor and a Method.

7135 Load System assembly as well as part of the standard library.
7137 * report.cs: Allow throwing exceptions on errors for debugging.
7139 * modifiers.cs: Do not use `parent', instead use the real type
7140 container to evaluate permission settings.
7142 * class.cs: Put Ravi's patch back in. He is right, and we will
7143 have to cope with the
7145 2001-09-14 Ravi Pratap <ravi@ximian.com>
7147 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
7148 FamORAssem, not FamANDAssem.

7152 * driver.cs: Added --parse option that only parses its input files
7155 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
7156 incorrect. IsTopLevel is not used to tell whether an object is
7157 root_types or not (that can be achieved by testing this ==
7158 root_types). But to see if this is a top-level *class* (not
7159 necessarly our "toplevel" container).
7161 2001-09-14 Ravi Pratap <ravi@ximian.com>
7163 * enum.cs (Enum::Define): Modify to call the Lookup method on the
7164 parent instead of a direct call to GetType.
7166 2001-09-14 Ravi Pratap <ravi@ximian.com>
7168 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
7169 Modifiers.TypeAttr. This should just be a call to that method.
7171 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
7172 object so that we can determine if we are top-level or not.
7174 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
7177 * enum.cs (Enum::Define): Ditto.
7179 * modifiers.cs (FieldAttr): Re-write.
7181 * class.cs (TypeContainer::IsTopLevel): Change accessibility to public.
7182 (TypeContainer::HaveStaticConstructor): New property to provide access
7183 to precisely that info.
7185 * modifiers.cs (MethodAttr): Re-write.
7186 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
7188 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
7189 of top-level types as claimed.
7191 2001-09-13 Miguel de Icaza <miguel@ximian.com>
7193 * expression.cs (MemberLookup): Fruitless attempt to lookup
7194 constructors. Maybe I need to emit default constructors? That
7195 might be it (currently .NET emits this for me automatically).
7196 (Invocation::OverloadResolve): Cope with Arguments == null.
7197 (Invocation::EmitArguments): new function, shared by the new
7199 (Invocation::Emit): Handle static and instance methods. Emit
7200 proper call instruction for virtual or non-virtual invocations.
7201 (New::Emit): Implement.
7202 (New::Resolve): Implement.
7203 (MemberAccess:Resolve): Implement.

7206 (FieldExpr::Resolve): Set type.
7208 * support.cs: Handle empty arguments.

7211 SimpleLookup): Auxiliary routines to help parse a qualifier
7214 Update qualifier_identifier rule.
7216 * codegen.cs: Removed debugging messages.
7218 * class.cs: Make this a global thing, this acts just as a "key" to
7219 objects that we might have around.
7221 (Populate): Only initialize method_builders_to_methods once.
7223 * expression.cs (PropertyExpr): Initialize type from the
7226 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
7227 Resolve pattern. Attempt to implicitly convert value to boolean.
7230 * expression.cs: Set the type for the int32/int32 argument case.
7231 (Binary::ResolveOperator): Set the return type to boolean for
7232 comparission operators
7234 * typemanager.cs: Remove debugging print code.
7236 (Invocation::Resolve): resolve type.
7238 * class.cs: Allocate a MemberInfo of the correct size, as the code
7239 elsewhere depends on the test to reflect the correct contents.

7251 on methods because System.Reflection bit us again.
7253 * support.cs: New file, contains an interface ParameterData and
7254 two implementations: ReflectionParameters and InternalParameters

7571 will is used during the tree rewriting as we resolve them during

7747 and re-write the code in the actions to extract the specific and
7748 general catch clauses by being a little smart ;-)
7750 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
7751 Hooray, try and catch statements parse fine !

7809 instead of ignoring the rank_specifiers.
7810 (expression_list): Implement to collect the expressions

7815 (opt_array_initializer): Modify accordingly.

7852 beginning, will continue tomorrow with more touches of polish. We
7853 handle the fundamentals of if, while, do, for, return. Others are
7854 trickier and I need to start working on invocations soon.
7856 * gen-treedump.cs: Bug fix, use s.Increment here instead of
7859 * codegen.cs (EmitContext): New struct, used during code
7860 emission to keep a context. Most of the code generation will be
7863 * cs-parser.jay: Add embedded blocks to the list of statements of
7864 this block. So code generation proceeds in a top down fashion.
7866 2001-08-23 Miguel de Icaza <miguel@ximian.com>
7868 * statement.cs: Add support for multiple child blocks.
7870 2001-08-22 Miguel de Icaza <miguel@ximian.com>
7872 * codegen.cs (EmitCode): New function, will emit the code for a
7873 Block of code given a TypeContainer and its ILGenerator.
7875 * statement.cs (Block): Standard public readonly optimization.
7876 (Block::Block constructors): Link children.
7877 (Block::Child): Child Linker.
7878 (Block::EmitVariables): Emits IL variable declarations.
7880 * class.cs: Drop support for MethodGroups here, delay until
7882 (Method::): Applied the same simplification that I did before, and
7883 move from Properties to public readonly fields.
7884 (Method::ParameterTypes): Returns the parameter types for the
7885 function, and implements a cache that will be useful later when I
7886 do error checking and the semantic analysis on the methods is
7888 (Constructor::GetCallingConvention): Renamed from CallingConvetion
7889 and made a method, optional argument tells whether this is a class
7890 or a structure to apply the `has-this' bit.
7891 (Method::GetCallingConvention): Implement, returns the calling
7893 (Method::Define): Defines the type, a second pass is performed
7894 later to populate the methods.
7896 (Constructor::ParameterTypes): implement a cache similar to the
7897 one on Method::ParameterTypes, useful later when we do semantic
7900 (TypeContainer::EmitMethod): New method. Emits methods.
7902 * expression.cs: Removed MethodGroup class from here.
7904 * parameter.cs (Parameters::GetCallingConvention): new method.
7906 2001-08-21 Miguel de Icaza <miguel@ximian.com>
7908 * class.cs (TypeContainer::Populate): Drop RootContext from the
7911 (Constructor::CallingConvention): Returns the calling convention.
7912 (Constructor::ParameterTypes): Returns the constructor parameter
7915 (TypeContainer::AddConstructor): Keep track of default constructor
7916 and the default static constructor.
7918 (Constructor::) Another class that starts using `public readonly'
7919 instead of properties.
7921 (Constructor::IsDefault): Whether this is a default constructor.
7923 (Field::) use readonly public fields instead of properties also.
7925 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
7926 track of static constructors; If none is used, turn on
7927 BeforeFieldInit in the TypeAttributes.
7929 * cs-parser.jay (opt_argument_list): now the return can be null
7930 for the cases where there are no arguments.
7932 (constructor_declarator): If there is no implicit `base' or
7933 `this', then invoke the default parent constructor.
7935 * modifiers.cs (MethodAttr): New static function maps a set of
7936 modifiers flags into a MethodAttributes enum
7937 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
7938 MethodAttr, TypeAttr to represent the various mappings where the
7940 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
7942 2001-08-19 Miguel de Icaza <miguel@ximian.com>
7944 * parameter.cs (GetParameterInfo): Fix bug where there would be no
7947 * interface.cs (PopulateIndexer): Implemented the code generator
7948 for interface indexers.
7950 2001-08-17 Miguel de Icaza <miguel@ximian.com>
7952 * interface.cs (InterfaceMemberBase): Now we track the new status
7955 (PopulateProperty): Implement property population. Woohoo! Got
7956 Methods and Properties going today.
7958 Removed all the properties for interfaces, and replaced them with
7959 `public readonly' fields.
7961 2001-08-16 Miguel de Icaza <miguel@ximian.com>
7963 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
7964 initialize their hashtables/arraylists only when they are needed
7965 instead of doing this always.
7967 * parameter.cs: Handle refs and out parameters.
7969 * cs-parser.jay: Use an ArrayList to construct the arguments
7970 instead of the ParameterCollection, and then cast that to a
7973 * parameter.cs: Drop the use of ParameterCollection and use
7974 instead arrays of Parameters.
7976 (GetParameterInfo): Use the Type, not the Name when resolving
7979 2001-08-13 Miguel de Icaza <miguel@ximian.com>
7981 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
7982 and instead use public readonly fields.
7984 * class.cs: Put back walking code for type containers.
7986 2001-08-11 Miguel de Icaza <miguel@ximian.com>
7988 * class.cs (MakeConstant): Code to define constants.
7990 * rootcontext.cs (LookupType): New function. Used to locate types
7993 2001-08-08 Miguel de Icaza <miguel@ximian.com>
7995 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
7996 this System.Reflection code is. Kudos to Microsoft
7998 * typemanager.cs: Implement a type cache and avoid loading all
7999 types at boot time. Wrap in LookupType the internals. This made
8000 the compiler so much faster. Wow. I rule!
8002 * driver.cs: Make sure we always load mscorlib first (for
8003 debugging purposes, nothing really important).
8005 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
8006 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
8008 * rootcontext.cs: Lookup types on their namespace; Lookup types
8009 on namespaces that have been imported using the `using' keyword.
8011 * class.cs (TypeContainer::TypeAttr): Virtualize.
8012 (Class::TypeAttr): Return attributes suitable for this bad boy.
8013 (Struct::TypeAttr): ditto.
8014 Handle nested classes.
8015 (TypeContainer::) Remove all the type visiting code, it is now
8016 replaced with the rootcontext.cs code
8018 * rootcontext.cs (GetClassBases): Added support for structs.
8020 2001-08-06 Miguel de Icaza <miguel@ximian.com>
8022 * interface.cs, statement.cs, class.cs, parameter.cs,
8023 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
8024 Drop use of TypeRefs, and use strings instead.
8026 2001-08-04 Miguel de Icaza <miguel@ximian.com>
8030 * class.cs (Struct::Struct): set the SEALED flags after
8031 checking the modifiers.
8032 (TypeContainer::TypeAttr): new property, returns the
8033 TypeAttributes for a class.
8035 * cs-parser.jay (type_list): Oops, list production was creating a
8036 new list of base types.
8038 * rootcontext.cs (StdLib): New property.
8039 (GetInterfaceTypeByName): returns an interface by type name, and
8040 encapsulates error handling here.
8041 (GetInterfaces): simplified.
8042 (ResolveTree): Encapsulated all the tree resolution here.
8043 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
8046 * driver.cs: Add support for --nostdlib, to avoid loading the
8048 (Main): Do not put tree resolution here.
8050 * rootcontext.cs: Beginning of the class resolution.
8052 2001-08-03 Miguel de Icaza <miguel@ximian.com>
8054 * rootcontext.cs: Provide better error reporting.
8056 * cs-parser.jay (interface_base): set our $$ to be interfaces.
8058 * rootcontext.cs (CreateInterface): Handle the case where there
8059 are no parent interfaces.
8061 (CloseTypes): Routine to flush types at the end.
8062 (CreateInterface): Track types.
8063 (GetInterfaces): Returns an array of Types from the list of
8066 * typemanager.c (AddUserType): Mechanism to track user types (puts
8067 the type on the global type hash, and allows us to close it at the
8070 2001-08-02 Miguel de Icaza <miguel@ximian.com>
8072 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
8073 RecordInterface instead.
8075 * cs-parser.jay: Updated to reflect changes above.
8077 * decl.cs (Definition): Keep track of the TypeBuilder type that
8078 represents this type here. Not sure we will use it in the long
8079 run, but wont hurt for now.
8081 * driver.cs: Smaller changes to accomodate the new code.
8083 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
8086 * rootcontext.cs (CreateInterface): New method, used to create
8087 the System.TypeBuilder type for interfaces.
8088 (ResolveInterfaces): new entry point to resolve the interface
8090 (CodeGen): Property, used to keep track of the code generator.
8092 2001-07-26 Miguel de Icaza <miguel@ximian.com>
8094 * cs-parser.jay: Add a second production for delegate_declaration
8097 (enum_body): Put an opt_comma here instead of putting it on
8098 enum_body or enum_member_declarations so we can handle trailing
8099 commas on enumeration members. Gets rid of a shift/reduce.
8101 (type_list): Need a COMMA in the middle.
8103 (indexer_declaration): Tell tokenizer to recognize get/set
8105 * Remove old targets.
8107 * Re-add the parser target.
8109 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8111 * cs-parser.jay: Add precendence rules for a number of operators
8112 ot reduce the number of shift/reduce conflicts in the grammar.
8114 2001-07-17 Miguel de Icaza <miguel@ximian.com>
8116 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
8119 Get rid of old crufty code.
8121 * rootcontext.cs: Use this to keep track of the parsed
8122 representation and the defined types available to the program.
8124 * gen-treedump.cs: adjust for new convention.
8126 * type.cs: Split out the type manager, and the assembly builder
8129 * typemanager.cs: the type manager will live here now.
8131 * cil-codegen.cs: And the code generator here.
8133 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
8135 * makefile: Fixed up for easy making.
8137 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8139 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
8142 (unary_expression): Expand pre_increment_expression and
8143 post_decrement_expression to reduce a shift/reduce.
8145 2001-07-11 Simon Cozens
8147 * cs-tokenizer.cs: Hex numbers should begin with a 0.
8149 Improve allow_keyword_as_indent name.
8151 2001-06-19 Miguel de Icaza <miguel@ximian.com>
8153 * Adjustments for Beta2.
8155 2001-06-13 Miguel de Icaza <miguel@ximian.com>
8157 * decl.cs: Added `Define' abstract method.
8158 (InTransit): new property, used to catch recursive definitions.
8160 * interface.cs: Implement `Define'.
8162 * modifiers.cs: Map Modifiers.constants to
8163 System.Reflection.TypeAttribute flags.
8165 * class.cs: Keep track of types and user-defined types.
8166 (BuilderInit): New method for creating an assembly
8167 (ResolveType): New function to launch the resolution process, only
8168 used by interfaces for now.
8170 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
8171 that are inserted into the name space.
8173 2001-06-08 Miguel de Icaza <miguel@ximian.com>
8175 * ARGH. I have screwed up my tree so many times due to the use of
8176 rsync rather than using CVS. Going to fix this at once.
8178 * driver.cs: Objetify driver. Load assemblies, use assemblies to
8181 2001-06-07 Miguel de Icaza <miguel@ximian.com>
8183 * Experiment successful: Use System.Type rather that our own
8186 2001-05-25 Miguel de Icaza <miguel@ximian.com>
8188 * cs-parser.jay: Removed nsAliases from here.
8190 Use new namespaces, handle `using XXX;'
8192 * namespace.cs: Reimplemented namespace handling, use a recursive
8193 definition of the class. Now we can keep track of using clauses
8194 and catch invalid using clauses.
8196 2001-05-24 Miguel de Icaza <miguel@ximian.com>
8198 * gen-treedump.cs: Adapted for all the renaming.
8200 * expression.cs (Expression): this class now has a Type property
8201 which returns an expression Type.
8203 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
8204 `Type', as this has a different meaning now in the base
8206 2001-05-22 Miguel de Icaza <miguel@ximian.com>
8208 * interface.cs, class.cs: Removed from all the sources the
8209 references to signature computation, as we can not do method
8210 signature computation during the parsing time, as we are not
8211 trying to solve at that point distinguishing:
8215 void a (NS.Blah x) {}
8218 Which depending on the context might be valid or not, as we do not
8219 know if Blah is the same thing as NS.Blah at that point.
8221 * Redid everything so the code uses TypeRefs now instead of
8222 Types. TypeRefs are just temporary type placeholders, that need
8223 to be resolved. They initially have a pointer to a string and the
8224 current scope in which they are used. This is used later by the
8225 compiler to resolve the reference to an actual Type.
8227 * DeclSpace is no longer a CIR.Type, and neither are
8228 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
8229 are all DeclSpaces, but no Types.
8231 * type.cs (TypeRefManager): This implements the TypeRef manager,
8232 which keeps track of all the types that need to be resolved after
8233 the parsing has finished.
8235 2001-05-13 Miguel de Icaza <miguel@ximian.com>
8237 * ARGH. We are going to have to store `foreach' as a class rather
8238 than resolving it, as we need to verify error 1579 after name
8239 resolution. *OR* we could keep a flag that says `This request to
8240 IEnumerator comes from a foreach statement' which we can then use
8241 to generate the error.
8243 2001-05-10 Miguel de Icaza <miguel@ximian.com>
8245 * class.cs (TypeContainer.AddMethod): we now add methods to the
8246 MethodGroup instead of the method hashtable.
8248 * expression.cs: Add MethodGroup abstraction, which gets us one
8249 step closer to the specification in the way we handle method
8252 * cs-parser.jay (primary_expression): qualified_identifier now
8253 tried to match up an identifier to a local variable reference or
8254 to a parameter reference.
8256 current_local_parameters is now a parser global variable that
8257 points to the current parameters for the block, used during name
8260 (property_declaration): Now creates an implicit `value' argument to
8263 2001-05-09 Miguel de Icaza <miguel@ximian.com>
8265 * parameter.cs: Do not use `param' arguments as part of the
8266 signature, per the spec.
8268 2001-05-08 Miguel de Icaza <miguel@ximian.com>
8270 * decl.cs: Base class for classes, structs and interfaces. This
8271 is the "Declaration Space"
8273 * cs-parser.jay: Use CheckDef for checking declaration errors
8274 instead of having one on each function.
8276 * class.cs: Factor out some code for handling error handling in
8277 accordance to the "Declarations" section in the "Basic Concepts"
8278 chapter in the ECMA C# spec.
8280 * interface.cs: Make all interface member classes derive from
8281 InterfaceMemberBase.
8283 2001-05-07 Miguel de Icaza <miguel@ximian.com>
8285 * Many things: all interfaces are parsed and generated in
8286 gen-treedump. Support for member variables, constructors,
8287 destructors, properties, constants is there.
8289 Beginning of the IL backend, but very little done, just there for
8292 2001-04-29 Miguel de Icaza <miguel@ximian.com>
8294 * cs-parser.jay: Fix labeled statement.
8296 * cs-tokenizer.cs (escape): Escape " and ' always.
8297 ref_line, ref_name: keep track of the line/filename as instructed
8298 by #line by the compiler.
8301 2001-04-27 Miguel de Icaza <miguel@ximian.com>
8303 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
8304 to match the values in System.CodeDOM.
8306 Divid renamed to Divide.
8308 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
8310 (Statements.set): remove.
8312 * System.CodeDOM/CodeCatchClause.cs: always have a valid
8315 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
8316 falseStatements always have valid values.
8318 * cs-parser.jay: Use System.CodeDOM now.
