47 necessary (fixes #27713).
49 2002-08-01 Martin Baulig <martin@gnome.org>
51 * ecore.cs (Expression.report118): Renamed to Error118 and made

124 and resolvings from Emit to Resolve.
126 * statement.cs (For): Moved all code that does variable lookups
127 and resolvings from Emit to Resolve.
129 * statement.cs (Using): Moved all code that does variable lookups
130 and resolvings from Emit to Resolve.
132 2002-07-29 Martin Baulig <martin@gnome.org>
134 * attribute.cs (Attribute.Resolve): Explicitly catch a
135 System.NullReferenceException when creating the

201 Fixes bug #24007, added test-152.cs.
203 2002-07-27 Martin Baulig <martin@gnome.org>
205 * expression.cs (Invocation.EmitArguments): When calling a varargs
206 function with only its fixed arguments, we need to pass an empty
209 2002-07-27 Martin Baulig <martin@gnome.org>
211 Mono 0.13 has been released.
213 2002-07-25 Miguel de Icaza <miguel@ximian.com>
215 * driver.cs: Rename --resource to --linkres, because that is what
216 we do currently, we dont support --resource yet.
218 * cs-tokenizer.cs: Fix test for reporting endif mismatches.
220 2002-07-25 Martin Baulig <martin@gnome.org>
222 * class.cs (MethodData): New public class. This is a `method builder'
223 class for a method or one accessor of a Property/Indexer/Event.
224 (MethodData.GetMethodFlags): Moved here from MemberBase.

226 (MethodData.ApplyObsoleteAttribute): Likewise.
227 (MethodData.ApplyConditionalAttribute): Likewise.
228 (MethodData.ApplyDllImportAttribute): Likewise.
229 (MethodData.CheckAbstractAndExternal): Likewise.
230 (MethodData.Define): Formerly knows as MemberBase.DefineMethod().
231 (MethodData.Emit): Formerly known as Method.Emit().
232 (MemberBase): Moved everything which was specific to a single
233 accessor/method to MethodData.
234 (Method): Create a new MethodData and call Define() and Emit() on it.
235 (Property, Indexer, Event): Create a new MethodData objects for each
236 accessor and call Define() and Emit() on them.
238 2002-07-25 Martin Baulig <martin@gnome.org>
240 Made MethodCore derive from MemberBase to reuse the code from there.
241 MemberBase now also checks for attributes.
243 * class.cs (MethodCore): Derive from MemberBase, not MemberCore.
244 (MemberBase.GetMethodFlags): Moved here from class Method and marked
246 (MemberBase.DefineAccessor): Renamed to DefineMethod(), added
247 `CallingConventions cc' and `Attributes opt_attrs' arguments.
248 (MemberBase.ApplyAttributes): New virtual method; applies the
249 attributes to a method or accessor.
250 (MemberBase.ApplyObsoleteAttribute): New protected virtual method.
251 (MemberBase.ApplyConditionalAttribute): Likewise.
252 (MemberBase.ApplyDllImportAttribute): Likewise.
253 (MemberBase.CheckAbstractAndExternal): Likewise.

258 initialize ParameterTypes and ParameterInfo.
259 (Method.GetReturnType): We can now simply return the MemberType.
260 (Method.GetMethodFlags): Override the MemberBase version and add
261 the conditional flags.
262 (Method.CheckBase): Moved some code from Define() here, call
263 DoDefineParameters() here.
264 (Method.Define): Use DoDefine() and DefineMethod() from MemberBase
265 here to avoid some larger code duplication.
266 (Property.Emit, Indexer.Emit): Call CheckAbstractAndExternal() to
267 ensure that abstract and external accessors don't declare a body.
269 * attribute.cs (Attribute.GetValidPieces): Make this actually work:
270 `System.Attribute.GetCustomAttributes (attr.Type)' does a recursive
271 lookup in the attribute's parent classes, so we need to abort as soon
272 as we found the first match.
273 (Attribute.Obsolete_GetObsoleteMessage): Return the empty string if
274 the attribute has no arguments.
276 * typemanager.cs (TypeManager.AddMethod): Now takes a MemberBase instead
279 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
281 * cs-parser.jay: reverted previous patch.
283 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
285 * cs-parser.jay: fixed bug #22119.
287 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
289 * attribute.cs: fixed compilation. The error was:
290 "attribute.cs(571,17): error CS0177: The out parameter 'is_error' must
291 be assigned to before control leaves the current method."
292 [FIXME: Filed as bug #28186: MCS must report this error.]
294 2002-07-25 Martin Baulig <martin@gnome.org>
296 * attribute.cs (Attribute.Conditional_GetConditionName): New static
297 method to pull the condition name ouf of a Conditional attribute.
298 (Attribute.Obsolete_GetObsoleteMessage): New static method to pull
299 the obsolete message and error flag out of an Obsolete attribute.
301 * class.cs (Method.GetMethodFlags): New public method to get the
302 TypeManager.MethodFlags for this method.
303 (Method.ApplyConditionalAttribute, Method.ApplyObsoleteAttribute): New
305 (Method.Define): Get and apply the Obsolete and Conditional attributes;
306 if we're overriding a virtual function, set the new private variable
307 `parent_method'; call the new TypeManager.AddMethod().
309 * typemanager.cs (TypeManager.AddMethod): New static method. Stores
310 the MethodBuilder and the Method in a PtrHashtable.
311 (TypeManager.builder_to_method): Added for this purpose.
312 (TypeManager.MethodFlags): Added IsObsoleteError.
313 (TypeManager.GetMethodFlags): Added `Location loc' argument. Lookup
314 Obsolete and Conditional arguments in MethodBuilders. If we discover
315 an Obsolete attribute, emit an appropriate warning 618 / error 619 with
316 the message from the attribute.
318 2002-07-24 Martin Baulig <martin@gnome.org>
320 * cs-tokenizer.cs: Eat up trailing whitespaces and one-line comments in
321 preprocessor directives, ensure that the argument to #define/#undef is
322 exactly one identifier and that it's actually an identifier.
324 Some weeks ago I did a `#define DEBUG 1' myself and wondered why this
327 2002-07-24 Martin Baulig <martin@gnome.org>
329 * statement.cs (Foreach.ForeachHelperMethods): Added `Type element_type',
330 initialize it to TypeManager.object_type in the constructor.
331 (Foreach.GetEnumeratorFilter): Set `hm.element_type' to the return type
332 of the `hm.get_current' method if we're using the collection pattern.
333 (Foreach.EmitCollectionForeach): Use `hm.element_type' as the source type
334 for the explicit conversion to make it work when we're using the collection
335 pattern and the `Current' property has a different return type than `object'.
338 2002-07-24 Martin Baulig <martin@gnome.org>
340 * delegate.cs (Delegate.VerifyMethod): Simply return null if the method
341 does not match, but don't report any errors. This method is called in
342 order for all methods in a MethodGroupExpr until a matching method is
343 found, so we don't want to bail out if the first method doesn't match.
344 (NewDelegate.DoResolve): If none of the methods in the MethodGroupExpr
345 matches, report the 123. Fixes #28070.
347 2002-07-24 Martin Baulig <martin@gnome.org>
349 * expression.cs (ArrayAccess.EmitStoreOpcode): Moved the
350 TypeManager.TypeToCoreType() to the top of the method so the
351 following equality checks will work. Fixes #28107.
353 2002-07-24 Martin Baulig <martin@gnome.org>
355 * cfold.cs (ConstantFold.DoConstantNumericPromotions): "If either
356 operand is of type uint, and the other operand is of type sbyte,
357 short or int, the operands are converted to type long." -
358 Actually do what this comment already told us. Fixes bug #28106,
361 2002-07-24 Martin Baulig <martin@gnome.org>
363 * class.cs (MethodBase): New abstract class. This is now a base
364 class for Property, Indexer and Event to avoid some code duplication
365 in their Define() and DefineMethods() methods.
366 (MethodBase.DoDefine, MethodBase.DefineAccessor): Provide virtual
367 generic methods for Define() and DefineMethods().
368 (FieldBase): Derive from MemberBase, not MemberCore.
369 (Property): Derive from MemberBase, not MemberCore.
370 (Property.DefineMethod): Moved all the code from this method to the
371 new MethodBase.DefineAccessor(), just call it with appropriate
373 (Property.Define): Call the new Property.DoDefine(), this does some
374 sanity checks and we don't need to duplicate the code everywhere.
375 (Event): Derive from MemberBase, not MemberCore.
376 (Event.Define): Use the new MethodBase.DefineAccessor() to define the
377 accessors, this will also make them work with interface events.
378 (Indexer): Derive from MemberBase, not MemberCore.
379 (Indexer.DefineMethod): Removed, call MethodBase.DefineAccessor() insstead.
380 (Indexer.Define): Use the new MethodBase functions.
382 * interface.cs (InterfaceEvent.InterfaceEvent): Added `Location loc'
383 argument to the constructor.
384 (Interface.FindMembers): Added support for interface events.
385 (Interface.PopluateEvent): Implemented.
387 Added test-149.cs for this. This also fixes bugs #26067 and #24256.
389 2002-07-22 Miguel de Icaza <miguel@ximian.com>
391 * class.cs (TypeContainer.AddMethod): Adding methods do not use IsValid,
392 but this is required to check for a method name being the same as
393 the containing class.
397 2002-07-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
399 * interface.cs: initialize variable.
401 2002-07-23 Martin Baulig <martin@gnome.org>
403 Implemented the IndexerName attribute in interfaces.
405 * class.cs (TypeContainer.DefineIndexers): Don't set the indexer
406 name if this is an explicit interface implementation.
407 (Indexer.InterfaceIndexerName): New public variable. If we're
408 implementing an interface indexer, this is the IndexerName in that
409 interface. Otherwise, it's the IndexerName.
410 (Indexer.DefineMethod): If we're implementing interface indexer,
411 set InterfaceIndexerName. Use the new Pending.IsInterfaceIndexer
412 and Pending.ImplementIndexer methods.
413 (Indexer.Define): Also define the PropertyBuilder if we're
414 implementing an interface indexer and this is neither an explicit
415 interface implementation nor do the IndexerName match the one in
418 * pending.cs (TypeAndMethods): Added `MethodInfo [] need_proxy'.
419 If a method is defined here, then we always need to create a proxy
420 for it. This is used when implementing interface indexers.
421 (Pending.IsInterfaceIndexer): New public method.
422 (Pending.ImplementIndexer): New public method.
423 (Pending.InterfaceMethod): Added `MethodInfo need_proxy' argument.
424 This is used when implementing interface indexers to define a proxy
426 (Pending.VerifyPendingMethods): Look in the `need_proxy' array and
427 define a proxy if necessary.
429 * interface.cs (Interface.IndexerName): New public variable.
430 (Interface.PopulateIndexer): Set the IndexerName.
431 (Interface.DefineIndexers): New private method. Populate all the
432 indexers and make sure their IndexerNames match.
434 * typemanager.cs (IndexerPropertyName): Added support for interface
437 2002-07-22 Martin Baulig <martin@gnome.org>
439 * codegen.cs (EmitContext.HasReturnLabel): New public variable.
440 (EmitContext.EmitTopBlock): Always mark the ReturnLabel and emit a
441 ret if HasReturnLabel.
442 (EmitContext.TryCatchLevel, LoopBeginTryCatchLevel): New public
445 * statement.cs (Do.Emit, While.Emit, For.Emit, Foreach.Emit): Save
446 and set the ec.LoopBeginTryCatchLevel.
447 (Try.Emit): Increment the ec.TryCatchLevel while emitting the block.
448 (Continue.Emit): If the ec.LoopBeginTryCatchLevel is smaller than
449 the current ec.TryCatchLevel, the branch goes out of an exception
450 block. In this case, we need to use Leave and not Br.
452 2002-07-22 Martin Baulig <martin@gnome.org>
454 * statement.cs (Try.Emit): Emit an explicit ret after the end of the
455 block unless the block does not always return or it is contained in
456 another try { ... } catch { ... } block. Fixes bug #26506.
457 Added verify-1.cs to the test suite.
459 2002-07-22 Martin Baulig <martin@gnome.org>
461 * statement.cs (Switch.TableSwitchEmit): If we don't have a default,
462 then we do not always return. Fixes bug #24985.
464 2002-07-22 Martin Baulig <martin@gnome.org>
466 * expression.cs (Invocation.OverloadedResolve): Do the BetterFunction()
467 lookup on a per-class level; ie. walk up the class hierarchy until we
468 found at least one applicable method, then choose the best among them.
469 Fixes bug #24463 and test-29.cs.
471 2002-07-22 Martin Baulig <martin@gnome.org>
473 * typemanager.cs (TypeManager.ArrayContainsMethod): Don't check the
474 return types of the methods. The return type is not part of the
475 signature and we must not check it to make the `new' modifier work.
476 Fixes bug #27999, also added test-147.cs.
477 (TypeManager.TypeToCoreType): Added TypeManager.type_type.
479 * expression.cs (Invocation.DoResolve): Call TypeManager.TypeToCoreType()
480 on the method's return type.
482 2002-07-21 Martin Baulig <martin@gnome.org>
484 * assign.cs: Make this work if the rightmost source is a constant and
485 we need to do an implicit type conversion. Also adding a few more tests
486 to test-38.cs which should have caught this.
488 * makefile.gnu: Disable debugging, there's already the mcs-mono2.exe
489 target in the makefile for this. The makefile.gnu is primarily intended
490 for end-users who don't want to debug the compiler.
492 2002-07-21 Martin Baulig <martin@gnome.org>
494 * assign.cs: Improved the Assign class so it can now handle embedded
495 assignments (X = Y = Z = something). As a side-effect this'll now also
496 consume less local variables. test-38.cs now passes with MCS, added
497 a few new test cases to that test.
499 2002-07-20 Martin Baulig <martin@gnome.org>
501 * expression.cs (Binary.EmitBranchable): Emit correct unsigned branch
502 instructions. Fixes bug #27977, also added test-146.cs.
504 2002-07-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
506 * cs-tokenizer.cs: fixed getHex ().
508 2002-07-19 Martin Baulig <martin@gnome.org>
510 * expression.cs (Invocation.EmitParams): Use TypeManager.LookupType(),
511 not Type.GetType() to lookup the array type. This is needed when
512 we're constructing an array of a user-defined type.
513 (ArrayAccess.EmitDynamicInitializers): Only emit the Ldelema for
514 single-dimensional arrays, but also for single-dimensial arrays of
517 2002-07-19 Martin Baulig <martin@gnome.org>
519 * expression.cs (New.DoEmit): Create a new LocalTemporary each time
520 this function is called, it's not allowed to share LocalBuilders
523 2002-07-19 Martin Baulig <martin@gnome.org>
525 * expression.cs (Argument.Resolve): Report an error 118 when trying
526 to pass a type as argument.
528 2002-07-18 Martin Baulig <martin@gnome.org>
530 * ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
531 Conv_R_Un for the signed `long' type.
533 2002-07-15 Miguel de Icaza <miguel@ximian.com>
535 * expression.cs (MemberAccess.DoResolve): Do not reuse the field
536 `expr' for the temporary result, as that will fail if we do
537 multiple resolves on the same expression.
539 2002-07-05 Miguel de Icaza <miguel@ximian.com>
541 * ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
542 ec.TypeContainer for looking up aliases.
544 * class.cs (TypeContainer): Remove LookupAlias from here.
546 * decl.cs (DeclSpace); Move here.
548 2002-07-01 Miguel de Icaza <miguel@ximian.com>
550 * class.cs (FindMembers): Only call filter if the constructor
553 Also handle delegates in `NestedTypes' now. Now we will perform
554 type lookups using the standard resolution process. This also
557 * decl.cs (DeclSpace.ResolveType): New type resolution routine.
558 This uses Expressions (the limited kind that can be parsed by the
559 tree) instead of strings.
561 * expression.cs (ComposedCast.ToString): Implement, used to flag
562 errors since now we have to render expressions.
564 (ArrayCreation): Kill FormElementType. Use ComposedCasts in
567 * ecore.cs (SimpleName.ToString): ditto.
569 * cs-parser.jay: Instead of using strings to assemble types, use
570 Expressions to assemble the type (using SimpleName, ComposedCast,
571 MemberAccess). This should fix the type lookups in declarations,
572 because we were using a different code path for this.
574 * statement.cs (Block.Resolve): Continue processing statements
575 even when there is an error.
577 2002-07-17 Miguel de Icaza <miguel@ximian.com>
579 * class.cs (Event.Define): Also remove the `remove' method from
580 the list of pending items.
582 * expression.cs (ParameterReference): Use ldarg.N (0..3) to
583 generate more compact code.
585 2002-07-17 Martin Baulig <martin@gnome.org>
587 * const.cs (Const.LookupConstantValue): Add support for constant
588 `unchecked' and `checked' expressions.
589 Also adding test case test-140.cs for this.
591 2002-07-17 Martin Baulig <martin@gnome.org>
593 * statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
594 check whether mi.ReturnType implements the IEnumerator interface; the
595 `==' and the IsAssignableFrom() will fail in this situation.
597 2002-07-16 Ravi Pratap <ravi@ximian.com>
599 * ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix
602 2002-07-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
604 * expression.cs: fixed bug #27811.
606 2002-07-14 Miguel de Icaza <miguel@ximian.com>
608 * expression.cs (ParameterReference.AddressOf): Patch from Paolo
609 Molaro: when we are a ref, the value already contains a pointer
610 value, do not take the address of it.
612 2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
613 * removed mb-parser.jay and mb-tokenizer.cs
615 Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
617 * expression.cs: check against the building corlib void type.
619 Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
621 * ecore.cs: fix for valuetype static readonly fields: when
622 initializing them, we need their address, not the address of a copy.
624 Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
626 * typemanager.cs: register also enum_type in corlib.
628 Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
630 * class.cs: allow calling this (but not base) initializers in structs.
632 Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
634 * ecore.cs: make sure we compare against the building base types
637 Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
639 * typemanager.cs: fix TypeToCoreType() to handle void and object
640 (corlib gets no more typerefs after this change).
642 2002-07-12 Miguel de Icaza <miguel@ximian.com>
644 * expression.cs (ArrayCreation.EmitArrayArguments): use
645 Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
647 (ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
648 Conv_Ovf_I_Un for the array arguments. Even if C# allows longs as
649 array indexes, the runtime actually forbids them.
651 * ecore.cs (ExpressionToArrayArgument): Move the conversion code
652 for array arguments here.
654 * expression.cs (EmitLoadOpcode): System.Char is a U2, use that
655 instead of the default for ValueTypes.
657 (New.DoEmit): Use IsValueType instead of
658 IsSubclassOf (value_type)
659 (New.DoResolve): ditto.
660 (Invocation.EmitCall): ditto.
662 * assign.cs (Assign): ditto.
664 * statement.cs (Unsafe): Ok, so I got the semantics wrong.
665 Statements *are* currently doing part of their resolution during
668 Expressions do always resolve during resolve, but statements are
669 only required to propagate resolution to their children.
671 2002-07-11 Miguel de Icaza <miguel@ximian.com>
673 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
675 (LoadAssembly): Do not add the dll if it is already specified
677 (MainDriver): Add the System directory to the link path at the end,
678 after all the other -L arguments.
680 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
681 wrong opcode for loading bytes and bools (ldelem.i1 instead of
682 ldelem.u1) and using the opposite for sbytes.
684 This fixes Digger, and we can finally run it.
686 * driver.cs (UnixParseOption): Move the option parsing here.
687 (CSCParseOption): Implement CSC-like parsing of options.
689 We now support both modes of operation, the old Unix way, and the
690 new CSC-like way. This should help those who wanted to make cross
693 The only thing broken is that /r:, /reference: and /lib: are not
694 implemented, because I want to make those have the same semantics
695 as the CSC compiler has, and kill once and for all the confussion
696 around this. Will be doing this tomorrow.
698 * statement.cs (Unsafe.Resolve): The state is checked during
699 resolve, not emit, so we have to set the flags for IsUnsfe here.
701 2002-07-10 Miguel de Icaza <miguel@ximian.com>
703 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
704 not catch the Error_ObjectRefRequired in SimpleName (as it is
705 possible to have a class/instance variable name that later gets
706 deambiguated), we have to check this here.
708 2002-07-10 Ravi Pratap <ravi@ximian.com>
710 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
711 make static and put into Expression.
713 (Event.Define): Register the private field of the event with the
714 TypeManager so that GetFieldFromEvent can get at it.
716 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
717 keep track of the private field associated with an event which
720 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
723 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
725 2002-07-10 Miguel de Icaza <miguel@ximian.com>
727 * expression.cs (Binary.EmitBranchable): this routine emits the
728 Binary expression in a branchable context. This basically means:
729 we need to branch somewhere, not just get the value on the stack.
731 This works together with Statement.EmitBoolExpression.
733 * statement.cs (Statement.EmitBoolExpression): Use
736 2002-07-09 Miguel de Icaza <miguel@ximian.com>
738 * statement.cs (For): Reduce the number of jumps in loops.
740 (For): Implement loop inversion for the For statement.
742 (Break): We can be breaking out of a Try/Catch controlled section
743 (foreach might have an implicit try/catch clause), so we need to
744 use Leave instead of Br.
746 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
747 now). If the instace expression supports IMemoryLocation, we use
748 the AddressOf method from the IMemoryLocation to extract the
749 address instead of emitting the instance.
751 This showed up with `This', as we were emitting the instance
752 always (Emit) instead of the Address of This. Particularly
753 interesting when This is a value type, as we dont want the Emit
754 effect (which was to load the object).
756 2002-07-08 Miguel de Icaza <miguel@ximian.com>
758 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
760 * statement.cs (Checked): Set the CheckedState during the resolve
761 process too, as the ConvCast operations track the checked state on
762 the resolve process, and not emit.
764 * cs-parser.jay (namespace_member_declaration): Flag that we have
765 found a declaration when we do. This is used to flag error 1529
767 * driver.cs: Report ok when we display the help only.
769 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
771 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
773 2002-07-04 Miguel de Icaza <miguel@ximian.com>
775 * cs-tokenizer.cs (define): We also have to track locally the
776 defines. AllDefines is just used for the Conditional Attribute,
777 but we also need the local defines for the current source code.
779 2002-07-03 Miguel de Icaza <miguel@ximian.com>
781 * statement.cs (While, For, Do): These loops can exit through a
782 Break statement, use this information to tell whether the
783 statement is the last piece of code.
785 (Break): Flag that we break.
787 * codegen.cs (EmitContexts): New `Breaks' state variable.
789 2002-07-03 Martin Baulig <martin@gnome.org>
791 * class.cs (TypeContainer.MethodModifiersValid): Allow override
792 modifiers in method declarations in structs. Otherwise, you won't
793 be able to override things like Object.Equals().
795 2002-07-02 Miguel de Icaza <miguel@ximian.com>
797 * class.cs (Method, Property, Indexer): Do not allow the public
798 modifier to be used in explicit interface implementations.
800 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
801 override modifiers in method declarations in structs
803 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
805 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
806 integer or real overflow, report an error
808 2002-07-02 Martin Baulig <martin@gnome.org>
810 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
811 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
812 to tell the runtime about our newly created System.Object and
813 System.ValueType types.
815 2002-07-02 Miguel de Icaza <miguel@ximian.com>
817 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
818 struct instead of Ldarg/Starg.
820 2002-07-02 Martin Baulig <martin@gnome.org>
822 * expression.cs (Indirection.Indirection): Call
823 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
825 2002-07-02 Martin Baulig <martin@gnome.org>
827 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
828 ValueType, call TypeManager.TypeToCoreType() on it.
829 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
830 the OpCodes.Newarr argument.
832 2002-07-02 Martin Baulig <martin@gnome.org>
834 * expression.cs (Invocation.EmitCall): When compiling corlib,
835 replace all calls to the system's System.Array type to calls to
836 the newly created one.
838 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
839 System.Array methods.
840 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
841 from the system's System.Array type which must be replaced.
843 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
845 * typemanager.cs: load unverifiable_code_ctor so we can build
846 corlib using the correct type. Avoid using GetTypeCode() with
848 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
849 TypeManager.object_type to allow building corlib.
851 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
853 * ecore.cs: handle System.Enum separately in LoadFromPtr().
855 2002-07-01 Martin Baulig <martin@gnome.org>
857 * class.cs: Make the last change actually work, we need to check
858 whether `ifaces != null' to avoid a crash.
860 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
862 * class.cs: when we build structs without fields that implement
863 interfaces, we need to add the interfaces separately, since there is
864 no API to both set the size and add the interfaces at type creation
867 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
869 * expression.cs: the dimension arguments to the array constructors
870 need to be converted if they are a long.
872 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
874 * class.cs: don't emit ldarg.0 if there is no parent constructor
875 (fixes showstopper for corlib).
877 2002-06-29 Martin Baulig <martin@gnome.org>
879 MCS now compiles corlib on GNU/Linux :-)
881 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
882 ie. check for MethodImplOptions.InternalCall.
884 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
885 and TypeManager.attribute_type are null, so we must explicitly check
886 whether parent is not null to find out whether it's an attribute type.
887 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
888 and SetBuilder, not only if the property is neither abstract nor external.
889 This is necessary to set the MethodImplOptions on the accessor methods.
890 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
891 SetBuilder, see Property.Emit().
893 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
894 populate "System.Object", "System.ValueType" and "System.Attribute" since
895 they've already been populated from BootCorlib_PopulateCoreTypes().
897 2002-06-29 Martin Baulig <martin@gnome.org>
899 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
900 is the NullLiteral, we also need to make sure that target_type is not
903 2002-06-29 Martin Baulig <martin@gnome.org>
905 * rootcontext.cs (RootContext.ResolveCore): We must initialize
906 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
907 before calling BootstrapCorlib_ResolveDelegate ().
909 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
911 * statement.cs: fixed build-breaker. All tests passed ok.
913 2002-06-27 Martin Baulig <martin@gnome.org>
915 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
916 for System.Decimal when compiling corlib.
918 2002-06-27 Martin Baulig <martin@gnome.org>
920 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
921 switch blocks which contain nothing but a default clause.
923 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
925 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
927 2002-06-27 Martin Baulig <martin@gnome.org>
929 * ecore.cs (PropertyExpr.PropertyExpr): Call
930 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
932 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
933 is already a TypeBuilder.
935 2002-06-27 Martin Baulig <martin@gnome.org>
937 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
938 `target_type == TypeManager.array_type', not IsAssignableFrom() in
939 the "from an array-type to System.Array" case. This makes it work
940 when compiling corlib.
942 2002-06-27 Martin Baulig <martin@gnome.org>
944 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
945 non-static PropertyExpr, set its InstanceExpression. This makes
946 the `ICollection.Count' property work in System/Array.cs.
948 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
950 * driver.cs: Made error handling more consistent. Errors now
951 tracked by Report class, so many methods which used to return int
952 now return void. Main() now prints success/failure and
953 errors/warnings message.
955 Renamed '--probe' compiler argument to '--expect-error'. Removed
956 the magic number return values (123 and 124). Now, if the
957 expected error occurs, the compiler exits with success (exit value
958 0). If the compilation completes without seeing that particular
959 error, the compiler exits with failure (exit value 1). The
960 makefile in mcs/errors has been changed to handle the new behaviour.
962 * report.cs: Made 'expected error' number a property and renamed
963 it from 'Probe' to 'ExpectedError'.
965 * genericparser.cs: Removed error handling support, since it is
966 now all done by Report class.
968 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
969 class, so parse() no longer returns an int.
971 * namespace.cs: Use Report.Error instead of GenericParser.error
973 2002-06-22 Miguel de Icaza <miguel@ximian.com>
975 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
976 TypeContainer.AddOperator): At the front of the list put the
977 explicit implementations, so they get resolved/defined first.
979 2002-06-21 Miguel de Icaza <miguel@ximian.com>
981 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
982 interface type is implemented by this TypeContainer. Used during
983 explicit interface implementation.
985 (Property.Define, Indexer.Define, Method.Define): Validate that
986 the given interface in the explicit implementation is one of the
987 base classes for the containing type.
989 Also if we are explicitly implementing an interface, but there is
990 no match in the pending implementation table, report an error.
992 (Property.Define): Only define the property if we are
993 not explicitly implementing a property from an interface. Use the
994 correct name also for those properties (the same CSC uses,
995 although that is really not needed).
997 (Property.Emit): Do not emit attributes for explicitly implemented
998 properties, as there is no TypeBuilder.
1000 (Indexer.Emit): ditto.
1002 Hiding then means that we do not really *implement* a pending
1003 implementation, which makes code fail.
1005 2002-06-22 Martin Baulig <martin@gnome.org>
1007 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
1008 the return value of Object.GetType(). [FIXME: we need to do this whenever
1009 we get a type back from the reflection library].
1011 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
1013 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
1015 2002-06-20 Miguel de Icaza <miguel@ximian.com>
1017 * attribute.cs: Return null if we can not look up the type.
1019 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
1020 the interface types found.
1022 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
1023 interface types found.
1025 * typemanager.cs (GetInterfaces): Make this routine returns alll
1026 the interfaces and work around the lame differences between
1027 System.Type and System.Reflection.Emit.TypeBuilder in the results
1028 result for GetInterfaces.
1030 (ExpandInterfaces): Given an array of interface types, expand and
1031 eliminate repeated ocurrences of an interface. This expands in
1032 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
1035 2002-06-21 Martin Baulig <martin@gnome.org>
1037 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
1040 2002-06-21 Martin Baulig <martin@gnome.org>
1042 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
1043 and called with one of the core types, return the corresponding typebuilder for
1046 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
1049 2002-06-21 Martin Baulig <martin@gnome.org>
1051 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
1052 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
1053 (Expression.ConvertReferenceExplicit): Likewise.
1055 * expression.cs (ElementAccess.DoResolve): Likewise.
1056 (ElementAccess.DoResolveLValue): Likewise.
1058 2002-06-10 Martin Baulig <martin@gnome.org>
1060 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
1061 add the "value" parameter to the parameter list.
1063 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
1066 2002-06-19 Miguel de Icaza <miguel@ximian.com>
1068 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
1069 the argument to an int, uint, long or ulong, per the spec. Also
1070 catch negative constants in array creation.
1072 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
1074 * class.cs: do not allow the same interface to appear twice in
1075 the definition list.
1077 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
1079 * ecore.cs: don't use ldlen with System.Array.
1081 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
1083 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
1085 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
1087 * modifiers.cs: produce correct field attributes for protected
1088 internal. Easy fix so miguel can work on ther harder stuff:-)
1090 2002-06-18 Miguel de Icaza <miguel@ximian.com>
1092 * pending.cs: New file. Move the code from class.cs here.
1093 Support clearning the pending flag for all methods (when not doing
1094 explicit interface implementation).
1096 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
1098 * rootcontext.cs: added a couple more types needed to bootstrap.
1100 2002-06-17 Miguel de Icaza <miguel@ximian.com>
1102 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
1103 constructor in the type, instead of any constructor in the type
1104 hierarchy. Thanks to Paolo for finding this bug (it showed up as
1105 a bug in the Mono runtime when applying the params attribute).
1107 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1108 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
1110 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
1112 * expression.cs (Unary.ResolveOperator): Use TypeManager
1113 to resolve the type.
1115 2002-06-13 Ravi Pratap <ravi@ximian.com>
1117 * cs-parser.jay (enum_member_declaration): Pass in the attributes
1120 * enum.cs (AddEnumMember): Add support to store the attributes associated
1121 with each member too.
1123 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
1124 field builders too - this takes care of the enum member case.
1126 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
1128 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
1129 address-of operator on both value types and pointers.
1131 2002-06-10 Martin Baulig <martin@gnome.org>
1133 * interface.cs (Interface.PopulateIndexer): Add the indexer's
1134 PropertyBuilder to the `property_builders' list.
1136 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
1137 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
1138 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
1139 find any indexers which are inherited from an interface.
1141 2002-06-09 Martin Baulig <martin@gnome.org>
1143 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
1144 the same type as the constant if necessary. There's also a test-130.cs
1147 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
1149 * typemanager.cs (TypeManager.ChangeType): Previously known as
1150 Enum.ChangeEnumType().
1152 2002-06-09 Martin Baulig <martin@gnome.org>
1154 * expression.cs (Cast.TryReduce): Added support for consts.
1156 2002-06-08 Ravi Pratap <ravi@ximian.com>
1158 * class.cs (Accessor): Hold attributes information so we can pass
1161 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
1162 Modify to pass in attributes attached to the methods.
1164 (add_accessor_declaration, remove_accessor_declaration): Ditto.
1166 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
1167 to handle the Accessor kind :-)
1169 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
1171 2002-06-08 Martin Baulig <martin@gnome.org>
1173 * expression.cs (Unary.TryReduceNegative): Added support for
1176 2002-06-08 Martin Baulig <martin@gnome.org>
1178 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
1179 name can't be found in the `defined_names' - the caller will do a
1180 MemberLookup in this case and thus find methods in System.Enum
1181 such as Enum.IsDefined().
1183 2002-06-08 Martin Baulig <martin@gnome.org>
1185 * enum.cs (Enum.ChangeEnumType): This is a custom version of
1186 Convert.ChangeType() which works with TypeBuilder created types.
1187 (Enum.LookupEnumValue, Enum.Define): Use it here.
1189 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
1190 `TypeBuilder.BaseType != null' check.
1191 (TypeContainer.FindMembers): Only lookup parent members if we
1192 actually have a parent.
1193 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
1194 (ConstructorInitializer.Resolve): Likewise.
1196 * interface.cs (Interface.FindMembers): Added
1197 `TypeBuilder.BaseType != null' check.
1199 * rootcontext.cs (RootContext.ResolveCore): Added
1200 "System.Runtime.CompilerServices.IndexerNameAttribute" to
1201 classes_second_stage.
1203 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
1204 debug_type and trace_type when compiling with --nostdlib.
1206 2002-06-07 Martin Baulig <martin@gnome.org>
1208 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
1209 (AddField): Set it to true when adding a non-static field.
1210 (DefineType): Use `have_nonstatic_fields' to find out whether we
1211 have non-static fields, not `Fields != null'.
1213 2002-06-02 Miguel de Icaza <miguel@ximian.com>
1215 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
1216 dereferencing a null on the static-field code path)
1218 2002-05-30 Martin Baulig <martin@gnome.org>
1220 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
1221 to take command line arguments. Use reflection to call the new
1222 custom `Initialize' function on the symbol writer and pass it the
1223 command line arguments.
1225 * driver.cs (--debug-args): New command line argument to pass command
1226 line arguments to the symbol writer.
1228 2002-05-28 Miguel de Icaza <miguel@ximian.com>
1230 * assign.cs (DoResolve): Forgot to do the implicit conversion to
1231 the target type for indexers and properties. Thanks to Joe for
1234 2002-05-27 Miguel de Icaza <miguel@ximian.com>
1236 * typemanager.cs (MethodFlags): returns the method flags
1237 (Obsolete/ShouldIgnore) that control warning emission and whether
1238 the invocation should be made, or ignored.
1240 * expression.cs (Invocation.Emit): Remove previous hack, we should
1241 not do this on matching a base type, we should do this based on an attribute
1243 Only emit calls to System.Diagnostics.Debug and
1244 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
1245 on the command line.
1247 * rootcontext.cs: Global settings for tracing and debugging.
1249 * cs-tokenizer.cs (define): New utility function to track
1250 defines. Set the global settings for TRACE and DEBUG if found.
1252 2002-05-25 Ravi Pratap <ravi@ximian.com>
1254 * interface.cs (Populate*): Pass in the TypeContainer as well as
1255 the DeclSpace as parameters so that we can create EmitContexts and
1256 then use that to apply attributes etc.
1258 (PopulateMethod, PopulateEvent, PopulateProperty)
1259 (PopulateIndexer): Apply attributes everywhere.
1261 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
1264 (ApplyAttributes): Update accordingly.
1266 We now apply interface attributes for all members too.
1268 2002-05-26 Miguel de Icaza <miguel@ximian.com>
1270 * class.cs (Indexer.Define); Correctly check if we are explicit
1271 implementation (instead of checking the Name for a ".", we
1272 directly look up if the InterfaceType was specified).
1274 Delay the creation of the PropertyBuilder.
1276 Only create the PropertyBuilder if we are not an explicit
1277 interface implementation. This means that explicit interface
1278 implementation members do not participate in regular function
1279 lookups, and hence fixes another major ambiguity problem in
1280 overload resolution (that was the visible effect).
1282 (DefineMethod): Return whether we are doing an interface
1285 * typemanager.cs: Temporary hack until we get attributes in
1286 interfaces (Ravi is working on that) and we get IndexerName
1287 support in interfaces.
1289 * interface.cs: Register the indexers as properties.
1291 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
1292 warning, I have verified that this is a bug in the .NET runtime
1293 (JavaScript suffers of the same problem).
1295 * typemanager.cs (MemberLookup): When looking up members for
1296 interfaces, the parent of an interface is the implicit
1297 System.Object (so we succeed in searches of Object methods in an
1298 interface method invocation. Example: IEnumerable x; x.ToString
1301 2002-05-25 Miguel de Icaza <miguel@ximian.com>
1303 * class.cs (Event): Events should also register if they do
1304 implement the methods that an interface requires.
1306 * typemanager.cs (MemberLookup); use the new GetInterfaces
1309 (GetInterfaces): The code used to lookup interfaces for a type is
1310 used in more than one place, factor it here.
1312 * driver.cs: Track the errors at the bottom of the file, we kept
1315 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
1316 instance if the method we are calling is static!
1318 2002-05-24 Miguel de Icaza <miguel@ximian.com>
1320 * attribute.cs (ApplyAttributes): Make this function filter out
1321 the IndexerName attribute (as that attribute in reality is never
1322 applied) and return the string constant for the IndexerName
1325 * class.cs (TypeContainer.Emit): Validate that all the indexers
1326 have the same IndexerName attribute, and if so, set the
1327 DefaultName attribute on the class.
1329 * typemanager.cs: The return value might contain other stuff (not
1330 only methods). For instance, consider a method with an "Item"
1331 property and an Item method.
1333 * class.cs: If there is a problem with the parameter types,
1336 2002-05-24 Ravi Pratap <ravi@ximian.com>
1338 * ecore.cs (ImplicitConversionExists): Wrapper function which also
1339 looks at user defined conversion after making a call to
1340 StandardConversionExists - we need this for overload resolution.
1342 * expression.cs : Update accordingly the various method calls.
1344 This fixes 2 bugs filed against implicit user defined conversions
1346 2002-05-22 Miguel de Icaza <miguel@ximian.com>
1348 * statement.cs: Track the result of the assignment.
1350 2002-05-21 Miguel de Icaza <miguel@ximian.com>
1352 * expression.cs (MemberAccess): Improved error reporting for
1353 inaccessible members.
1355 2002-05-22 Martin Baulig <martin@gnome.org>
1357 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
1358 itself with debugging support.
1360 2002-05-22 Martin Baulig <martin@gnome.org>
1362 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
1363 Removed, this isn't needed anymore.
1365 2002-05-20 Martin Baulig <martin@gnome.org>
1367 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
1368 be underlying type for an enum.
1370 2002-05-20 Miguel de Icaza <miguel@ximian.com>
1372 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
1373 that splits out the loading of just the core types.
1375 * rootcontext.cs (ResolveCore): Split the struct resolution in
1376 two, so we can load the enumeration underlying types before any
1379 * expression.cs (Is): Bandaid until we fix properly Switch (see
1380 bug #24985 for details).
1382 * typemanager.cs (ImplementsInterface): The hashtable will contain
1383 a null if there are no interfaces implemented.
1385 2002-05-18 Miguel de Icaza <miguel@ximian.com>
1387 * cs-parser.jay (indexer_declarator): It is fine to have array
1390 2002-05-17 Miguel de Icaza <miguel@ximian.com>
1392 * typemanager.cs: (RegisterBuilder): New function used to register
1393 TypeBuilders that implement interfaces. Since
1394 TypeBuilder.GetInterfaces (as usual) does not work with lame
1396 (AddUserType): register interfaces.
1398 (ImplementsInterface): Use the builder_to_ifaces hash if we are
1399 dealing with TypeBuilder. Also, arrays are showing up as
1400 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
1401 methods can not be invoked on them!
1403 * ecore.cs (ExplicitReferenceConversionExists): Made public.
1404 (ImplicitReferenceConversionExists): Split out from
1405 StandardConversionExists.
1407 * expression.cs (As): We were only implementing one of the three
1408 cases for the as operator. We now implement them all.
1409 (Is): Implement the various other cases for Is as well.
1411 * typemanager.cs (CACHE): New define used to control if we want or
1412 not the FindMembers cache. Seems to have a negative impact on
1413 performance currently
1415 (MemberLookup): Nested types have full acess to
1416 enclosing type members
1418 Remove code that coped with instance/static returns for events, we
1419 now catch this in RealFindMembers.
1421 (RealFindMembers): only perform static lookup if the instance
1422 lookup did not return a type or an event.
1424 2002-05-17 Miguel de Icaza <miguel@ximian.com>
1426 * assign.cs (CompoundAssign): We pass more semantic information
1427 now to Compound Assignments than we did before: now we have all
1428 the information at hand, and now we resolve the target *before* we
1429 do the expression expansion, which allows the "CacheValue" method
1430 to have the effect we intended (before, a [x] += 1 would generate
1431 two differen ArrayAccess expressions from the ElementAccess,
1432 during the resolution process).
1434 (CompoundAssign.DoResolve): Resolve target and original_source here.
1436 2002-05-16 Miguel de Icaza <miguel@ximian.com>
1438 * expression.cs (ArrayAccess): dropped debugging information.
1440 * typemanager.cs: Small bug fix: I was always returning i_members,
1441 instead of one of i_members or s_members (depending on which had
1444 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
1445 method is invoked before any code generation takes place, and it
1446 is a mechanism to inform that the expression will be invoked more
1447 than once, and that the method should use temporary values to
1448 avoid having side effects
1450 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
1452 * ecore.cs (Expression.CacheTemporaries): Provide empty default
1455 * expression.cs (Indirection, ArrayAccess): Add support for
1456 CacheTemporaries in these two bad boys.
1458 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
1460 (StoreFromPtr): Handle stobj as well.
1462 * expression.cs (UnaryMutator): Share more code.
1464 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
1465 down: I was not tracking the Filter function as well, which
1466 was affecting the results of the cache.
1468 2002-05-15 Miguel de Icaza <miguel@ximian.com>
1470 * attribute.cs: Remove the hack to handle the CharSet property on
1473 2002-05-14 Miguel de Icaza <miguel@ximian.com>
1475 * attribute.cs (DoResolve): More uglyness, we now only try to
1476 resolve the attribute partially, to extract the CharSet
1477 information (only if we are a StructLayout attribute). Otherwise
1479 (GetExtraTypeInfo): Add some code to conditionally kill in the
1480 future this. I am more and more convinced that the .NET
1481 framework has special code to handle the attribute setting on
1484 * expression.cs (IsParamsMethodApplicable): Revert my previous
1485 foreach change here, it was wrong.
1487 2002-05-13 Miguel de Icaza <miguel@ximian.com>
1489 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
1490 (pp_expr): do not abort on unknown input, just return.
1491 (eval): abort if there are pending chars.
1493 * attribute.cs (Attribute.Resolve): Positional parameters are
1494 optional. Deal with that case.
1496 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
1497 the Ansi/Unicode/Auto information for the type.
1499 (TypeContainer.DefineType): instantiate the EmitContext here, as
1500 we will be using it during the type definition (to resolve
1501 attributes) and during the emit phase.
1503 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
1504 to pull type information out of the attributes
1506 (Attribute.Resolve): track the constructor builder, and allow for
1507 multiple invocations (structs and classes will use this).
1509 * ecore.cs (MemberLookupFinal): new version with all the
1510 parameters customizable.
1512 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
1513 constructors. Return if the result value is null (as the error
1514 would have been flagged already by MemberLookupFinal)
1516 Do not allow instances of abstract classes or interfaces to be
1519 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
1520 We have to compare the assembly property here when dealing with
1521 FamANDAssem and Assembly access modifiers, because we might be
1522 creating an assembly from *modules* (that means that we are not
1523 getting TypeBuilders for types defined in other modules that are
1524 part of this assembly).
1526 (Method.Emit): If the method is marked abstract and has a body,
1529 (TypeContainer.DefineMembers): If both the defined member and the
1530 parent name match are methods, then do not emit any warnings: let
1531 the Method.Define routine take care of flagging warnings. But if
1532 there is a mismatch (method overrides something else, or method is
1533 overriwritten by something, then emit warning).
1535 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
1536 set to null, this means `do not check for the return type on the
1539 (Method.Define): set the return type for the method signature to
1540 null, so that we get methods with the same name and parameters and
1541 different return types. This is used to flag warning 114 (you are
1542 hiding a method, and you probably want to use the new/override
1545 * typemanager.cs (MemberLookup): Implemented proper access
1546 control, closing a long standing set of bug reports. The problem
1547 was that the Framework only has two bits: Public and NonPublic,
1548 and NonPublic includes private and protected methods, but we need
1549 to enforce the FamANDAssem, FamOrAssem and Family.
1551 2002-05-11 Miguel de Icaza <miguel@ximian.com>
1553 * statement.cs (GotoCase): Return true: Ammounts to giving up
1554 knowledge on whether we return or not, and letting the other case
1555 be responsible for it.
1557 2002-05-10 Miguel de Icaza <miguel@ximian.com>
1559 * driver.cs: Do not load directories for each file processed, only
1560 do it if there is a pattern.
1562 * ecore.cs: Report readonly assigns here as well, as we might have
1563 been resolved only by MemberAccess.
1565 (SimpleName.SimpleNameResolve): Also be useful for LValue
1566 resolution. We need this to propagate assign to local readonly variables
1568 * typemanager.cs: Use a ptrhashtable for the criteria, because we
1569 do not want to reuse potential criteria memory.
1571 * class.cs (MyEventBuilder): Set reflected_type;
1573 * ecore.cs (Constantify): Added support for constifying bools.
1575 (RootContext.LookupType): Added a cache for values looked up in
1576 the declaration space.
1578 * typemanager.cs (FindMembers): Now is a front-end to
1579 RealFindMembers, and provides a two-level hashtable-based cache to
1582 15% performance improvement: from 22.5 to 19.2 seconds.
1584 * expression.cs (IsParamsMethodApplicable): use foreach.
1585 (Invocation.DoResolve): ditto.
1586 (New.DoResolve): ditto.
1587 (ArrayCreation.DoResolve): ditto.
1589 * ecore.cs (FindMostEncompassingType): use foreach.
1591 * delegate.cs (NewDelegate.DoResolve): Use foreach
1593 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
1594 (RemoveMethods): use foreach.
1596 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
1597 nested foreach statements instead of for, and also break out of
1598 the inner loop once a match is found.
1600 (Invocation.OverloadResolve): Use foreach, simplify the code.
1602 2002-05-08 Miguel de Icaza <miguel@ximian.com>
1604 * cfold.cs (BinaryFold): During an enumeration evaluation context,
1605 we actually unwrap the expression to allow for extra information
1608 * expression.cs: Use Shr_Un on unsigned operations.
1610 2002-05-08 Ravi Pratap <ravi@ximian.com>
1612 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
1613 applicable operators was not being considered correctly. This closes
1614 the bug Miguel reported.
1616 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
1618 * attribute.cs: check that the type derives from System.Attribute
1619 and report the correct error in that case (moved the duplicate code to
1620 its own method, too).
1622 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
1624 * attribute.cs: lookup attribute type name as the spec says: first the
1625 bare attribute name and then name + "Attribute" (nant compiles with
1626 mcs after this fix).
1628 2002-05-07 Miguel de Icaza <miguel@ximian.com>
1630 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
1631 Because of the way we parse things, we should try to see if a
1632 UIntConstant can fit in an integer.
1634 2002-05-07 Ravi Pratap <ravi@ximian.com>
1636 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
1637 when we are in an explicit context.
1639 (ConvertReferenceExplicit): When converting from Iface type S to Class
1640 T make sure the rules are implemented as an OR.
1642 * parameter.cs (ParameterType): Make it a property for now although the
1643 purpose really isn't anything immediate.
1645 * expression.cs (Is*Applicable): Do better checking on the parameter type
1646 of a ref/out parameter. The ones from the system assemblies are already
1647 marked with the correct type so we don't need to do any correction.
1649 * ecore.cs (StandardConversionExists): Conversion from Interface types to
1650 the object type is standard too so include that.
1652 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1654 * ecore.cs (StandardConversionExists): Augment with missing code:
1655 deal with IntConstant, LongConstants and Enumerations.
1657 * assign.cs: Report the error, instead of failing silently
1659 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
1660 typecontainer that they are declared, because the
1661 typecontainer/namespace will have the list of using clauses that
1664 Assembly Attributes were escaping the normal registration
1667 (EmitCode): Apply attributes within an EmitContext that represents
1668 the container they were declared on.
1670 * cs-parser.jay: Track bases for structs. How did I get this wrong?
1672 2002-05-06 Ravi Pratap <ravi@ximian.com>
1674 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
1675 Revamp completely - make much cleaner as we now operate only
1678 (FindMostSpecificSource, FindMostSpecificTarget): New methods
1679 to implement the logic detailed in the spec more correctly.
1681 (UserDefinedConversion): Update accordingly.
1683 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1685 * statement.cs: Return flow analysis information up.
1687 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
1690 (token): Do not consume an extra character before calling
1693 2002-05-06 Piers Haken <piersh@friskit.com>
1695 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
1697 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1699 * class.cs (Constructor.Emit): Set the IsStatic flag in the
1700 EmitContext during the instance constructor initializer
1701 resolution, to stop access to instance variables.
1703 This is mandated by the spec, last paragraph of the `constructor
1704 initializers' section.
1706 2002-05-05 Miguel de Icaza <miguel@ximian.com>
1708 * cs-parser.jay, class.cs (Accessor): new class used to represent
1709 an accessor (get or set). In the past we used `null' to represent
1710 a missing accessor. But this is ambiguous because there was no
1711 way to tell in abstract indexers/properties if one of them was
1714 Now there is a way of addressing that.
1716 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
1717 instead of FindMembers.
1719 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
1720 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
1722 * attribute.cs: Treat indexers and properties as the same in terms
1723 of applying attributes
1725 * ecore.cs (FindMostEncompassedType): Use statically initialized
1726 EmptyExpressions()s like we do elsewhere to avoid creating useless
1727 objects (and we take this out of the tight loop).
1729 (GetConversionOperators): Move the code to extract the actual
1730 operators to a separate routine to clean things up.
1732 2002-05-04 Miguel de Icaza <miguel@ximian.com>
1734 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
1735 events are always registered FieldBuilders.
1737 * class.cs (FieldBase): New class shared by Fields
1739 * delegate.cs: If we are a toplevel delegate, use our full name.
1740 If we are a nested delegate, then only use our tail name.
1742 2002-05-02 Ravi Pratap <ravi@ximian.com>
1744 * expression.cs (IsApplicable): Ensure that we add the "&" to
1745 ref/out types before comparing it with the type of the argument.
1747 (IsParamsMethodApplicable): Ditto.
1749 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
1752 * delegate.cs : Handle the case when we have more than one applicable
1753 method. Flag an error only when we finish checking all.
1755 2002-05-02 Miguel de Icaza <miguel@ximian.com>
1757 * expression.cs: Add support for boolean static initializers.
1759 2002-05-01 Miguel de Icaza <miguel@ximian.com>
1761 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
1763 * parameter.cs (ComputeParameterTypes,
1764 ComputeAndDefineParameterTypes): Better error handling: now we
1765 clear the `types' cache if we fail during any of the type lookups.
1766 We also return the status code correctly to our caller
1768 * delegate.cs: If we fail to define a delegate, abort the extra
1771 * expression.cs (Binary.ResolveOperator): for
1772 operator==(object,object) and operator !=(object, object) we also
1773 have to verify that there is an implicit conversion from one to
1776 (ArrayAccess.DoResolve): Array Access can operate on
1779 2002-04-30 Miguel de Icaza <miguel@ximian.com>
1781 * assign.cs (CompoundAssign): A new class used as a "flag" that
1782 the assignment actually is happening as part of a compound
1783 assignment operator.
1785 During compound assignment, a few new rules exist to enable things
1792 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
1793 to the type of x) if y is implicitly convertible to the type of x,
1794 and the operator is a builtin operator and the return type of the
1795 operator is explicitly convertible to the type of x.
1797 * rootcontext.cs: Reset warning level to 2. 4 catches various
1798 "interesting" features in mcs, we must clean this up at some
1799 point, but currently am trying to kill other bugs ;-)
1801 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
1802 in container classes as well.
1804 * expression.cs (Binary.ResolveOperator): Handle string case
1805 before anything else (as operator overloading does emit an error
1806 before doing anything else).
1808 This code could go away when we move to a table driven model, but
1809 i could not come up with a good plan last night.
1811 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
1813 * typemanager.cs (CSharpName): reimplementation using regex.
1814 * class.cs: added null check for fields in Emit
1815 * rootcontext.cs: set warninglevel to 4
1817 2002-04-29 Miguel de Icaza <miguel@ximian.com>
1819 * typemanager.cs (CSharpName): reimplemented with Lupus
1822 2002-04-28 Miguel de Icaza <miguel@ximian.com>
1824 * statement.cs (If): correclty implement Resolve, because we were
1825 not catching sem errors in there. The same process is needed
1827 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
1830 (Statement.Warning_DeadCodeFound): Factorize code.
1831 (While): Report dead code here too.
1833 (Statement): Added Resolve virtual method to allow
1834 for resolution split from the emit code.
1836 2002-04-26 Miguel de Icaza <miguel@ximian.com>
1838 * statement.cs (EmitBoolExpression): No longer try to resolve the
1840 (MakeBoolean): New utility function that resolve, implicitly
1841 converts to boolean and tags the expression.
1844 (If, Do): Implement dead code elimination.
1845 (While): Implement loop inversion
1847 (Do, While, For, If): Resolve the expression prior to calling our
1850 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
1853 - added method Report28 (warning: program has more than one entry point)
1854 - added method IsEntryPoint, implements paragraph 10.1 of the spec
1855 - modified method Method.Define, the part at the end of the method
1857 * rootcontext.cs: added static public Location EntryPointLocation;
1859 * ../errors/cs0028.cs : Add test case for the above warning.
1862 - modified method CSharpName to allow arrays of primitive type to
1863 be printed nicely (e.g. instead of System.Int32[][] it now prints
1865 - added method CSharpSignature: returns the signature of a method
1866 in string format to be used in reporting errors, warnings, etc.
1868 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
1871 2002-04-26 Ravi Pratap <ravi@ximian.com>
1873 * delegate.cs (Define): Fix extremely silly bug where I was
1874 setting the type of the 'object' parameter of the BeginInvoke
1875 method to System.IAsyncResult instead of System.Object ;-)
1877 2002-04-26 Miguel de Icaza <miguel@ximian.com>
1879 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
1882 (Constructor.Emit): return if we fail to initialize the
1883 constructor. Another door closed!
1885 * expression.cs (New.DoResolve): Improve error message (from -6 to
1886 1501). Use DeclaredOnly lookup to find the exact constructor.
1888 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
1889 loop. This is useful.
1891 * cs-parser.jay: Adjust the default parameters so that destructors
1892 have the proper signature.
1894 2002-04-26 Martin Baulig <martin@gnome.org>
1896 * driver.cs (LoadAssembly): If `assembly' contains any characters
1897 which are only valid in path names and not in assembly names
1898 (currently slash, backslash and point), use Assembly.LoadFrom ()
1899 instead of Assembly.Load () on the `assembly' (before iteration
1900 over the link_paths).
1902 2002-04-26 Martin Baulig <martin@gnome.org>
1904 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
1906 2002-04-25 Miguel de Icaza <miguel@ximian.com>
1908 * class.cs (Property): use the new typemanager.MemberLookup
1910 (TypeContainer.MemberLookup): Implement using the
1911 TypeManager.MemberLookup now.
1913 * typemanager.cs: Make MemberLookup a function of the TypeManager,
1914 and return MemberInfos, so that these can be used without an
1915 EmitContext (what we had before).
1917 2002-04-24 Miguel de Icaza <miguel@ximian.com>
1919 * expression.cs: Fix the case where the argument to params if the
1920 type of the params. I omitted handling this before. Fixed
1922 2002-04-22 Miguel de Icaza <miguel@ximian.com>
1924 * driver.cs: Call BootCorlib_PopulateCoreType
1926 * class.cs (Property.CheckBase): Check for properties only, not
1929 * interface.cs: Temporary hack: try/catch around the
1930 CustomAttributeBuilder, because I am getting an exception that I
1933 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
1934 types whose definitions are required to be there (attributes are
1935 defined before standard types).
1937 Compute definitions as we boot the various types, as they are used
1938 immediately (value_type class will need object_type, but if we do
1939 not initialize object_type, we will pass a null, which will let
1940 the runtime pick the System.Object from the existing corlib, which
1941 is not what we want).
1943 2002-04-22 Patrik Torstensson <totte@labs2.com>
1945 * cs-tokenizer.cs: fixed a number of trim() issues.
1947 2002-04-22 Ravi Pratap <ravi@ximian.com>
1949 * expression.cs (Argument.Type): Ensure that we return the correct
1950 type when we have out or ref parameters [in which case we
1953 2002-04-22 Miguel de Icaza <miguel@ximian.com>
1955 * class.cs (Property, Indexer): Allow extern modifier in there.
1957 * typemanager.cs (InitBaseTypes): Initializes object_type and
1958 value_type, since those will be used early on during the bootstrap
1959 process to compile corlib.
1961 (InitCoreTypes): Move code from here to InitBaseTypes.
1963 2002-04-21 Miguel de Icaza <miguel@ximian.com>
1965 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
1966 single-dimension arrays as using the ldlen opcode.
1968 Daniel Lewis discovered this optimization.
1970 * typemanager.cs: Add signature for System.Array::get_Length
1972 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1974 * statement.cs: report the error when the foreach does not apply to an
1975 array nor a collection.
1977 2002-04-19 Miguel de Icaza <miguel@ximian.com>
1979 * expression.cs: Add implicit conversions to the operator ~.
1981 * constant.cs (DecimalConstant.Emit): Emit decimal value.
1983 * typemanager.cs: Locate the decimal constructor.
1985 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1987 * attribute.cs: use the new property of TypeOf.
1988 * expression.cs: added 'get' property around typearg.
1990 These changes fix a build breaker reported by NickD. Is this the
1991 correct way to fix? If not, please, revert my changes and make it
1994 2002-04-17 Miguel de Icaza <miguel@ximian.com>
1996 * attribute.cs: Add support for typeof in attribute invocations.
1997 I am not sure that this is right though.
1999 2002-04-14 Duncan Mak <duncan@ximian.com>
2001 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
2002 Binary.Operator.Division case.
2004 2002-04-13 Ravi Pratap <ravi@ximian.com>
2006 * class.cs (DefineType): Ensure that we do a proper check on
2007 attribute types and also register it with the TypeManager.
2009 (TypeContainer.Targets): The default for attribute types is
2010 AttributeTargets.All.
2012 * attribute.cs (ApplyAttributes): Registering the attribute type
2013 is done elsewhere, not when we discover we have a Usage attribute.
2015 2002-04-12 Ravi Pratap <ravi@ximian.com>
2017 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
2018 and get rid of is_delegate parameter.
2020 * everywhere : update.
2022 2002-04-12 Ravi Pratap <ravi@ximian.com>
2024 * cs-parser.jay (compilation_unit): Revamp completely to use
2025 some new ideas that I got from Rhys' grammar to solve the problems
2026 with assembly level attributes.
2028 (outer_declaration): New grammar production.
2030 (attribute_sections): Add.
2032 (opt_attributes): Base on attribute_sections
2034 (namespace_declaration): Allow opt_attributes to tackle the case
2035 when we have assembly level attributes - we are clever in this
2038 * attribute.cs (ApplyAttributes): Do not worry about assembly
2039 attributes in the non-global context.
2041 * rootcontext.cs (AddGlobalAttributes): Go back to using this
2042 instead of SetGlobalAttributes.
2044 * class.cs, rootcontext.cs : Ensure we define and generate
2045 attribute types before anything else.
2047 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
2048 and flag the new error -20 for the case when the attribute type
2049 does not have valid targets specified. csc does not catch this.
2051 * ../errors/errors.txt : update for error # -20
2053 2002-04-11 Ravi Pratap <ravi@ximian.com>
2055 * support.cs (InternalParameters.ParameterModifier): Do some null
2056 checking and return sane values.
2058 * class.cs (Method.Define): If we are a PInvoke method, ensure
2059 that we are static and extern. Report error # 601
2061 * ../errors/cs0601.cs : Add test case for the above error.
2063 2002-04-07 Ravi Pratap <ravi@ximian.com>
2065 * rootcontext.cs (attribute_types): We need to keep type of
2066 all attribute types separately and emit code for them first.
2068 (RegisterAttribute) : Implement.
2070 * class.cs (DefineType): Check if the current Type is a custom
2071 attribute type and register it accordingly.
2073 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
2074 adding the first attribute twice and rename to
2076 (SetGlobalAttributes): this.
2078 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
2081 * attribute.cs (ApplyAttributes): Take an additional argument telling us
2082 if we are processing global arguments. Hmm, I am unsure of this.
2084 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2086 * expression.cs: added static array of strings to avoid calling
2087 Enum.ToString () for Operator in Binary. Significant recover of
2090 2002-04-10 Miguel de Icaza <miguel@ximian.com>
2092 * class.cs (FindMembers): Allow the Builders of the various
2093 members to be null. If they are skip them. This only happens
2094 during the PInvoke declaration.
2096 2002-04-09 Miguel de Icaza <miguel@ximian.com>
2098 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
2099 failure, so we do not keep going afterwards.
2101 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
2102 wanted to pass `false' as the `is_delegate' argument. If this is
2103 the case, why not use delegate_type == null to mean `is_delegate =
2104 false' and anything else as is_delegate = true.
2106 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
2108 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
2109 code for the section, not the beginning of the tests.
2111 2002-04-08 Miguel de Icaza <miguel@ximian.com>
2113 * cfold.cs: Handle operator + (Enum x, Underlying x)
2115 * expression.cs (Binary): same. Warn about errors where we have
2116 Enum/Enum in operator + as well.
2118 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
2121 - added support for switch(bool)
2122 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
2123 - add TableSwitchEmit() to handle table-based switch statements
2125 2002-04-05 Ravi Pratap <ravi@ximian.com>
2127 * expression.cs (Invocation.OverloadResolve): Factor out code which
2128 does parameter compatibility checking with arguments so that we can
2129 re-use the code even from Delegate.VerifyApplicability
2131 (VerifyArgumentsCompat): Move above code here.
2133 * delegate.cs (VerifyApplicability): Get rid of duplicate code
2134 and instead make a call to the above method.
2136 2002-03-31 Ravi Pratap <ravi@ximian.com>
2138 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
2139 We use it to keep track of classes which are attribute types.
2141 2002-04-02 Miguel de Icaza <miguel@ximian.com>
2143 * delegate.cs (Delegate.Define): Correctly define the types in the
2144 presence of fixed and array parameters.
2146 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
2149 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
2150 include NonPublic after the first iteration.
2152 * class.cs (Indexer.CheckBase): Only check if both parents are
2155 * cs-parser.jay (accessor_body): If empty, set to null.
2157 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
2158 same code path here to resolve constants names that we did have in
2159 MemberAccess.DoResolve. There is too much code duplicated here.
2161 2002-04-01 Miguel de Icaza <miguel@ximian.com>
2163 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
2165 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
2168 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
2169 tokens, numbers and strings.
2171 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
2174 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
2175 asyncronous parameters and the regular parameters.
2177 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
2178 specify the target directory.
2180 * expression.cs: (This.DoResolve): Simplify
2181 (As.Emit): Optimize, do not generate IsInst if the expression is
2182 always of the given type.
2184 (Is.DoResolve): Bug fix, we were reporting both always/never for
2187 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
2188 creating too many unnecessary arrays.
2190 2002-03-31 Miguel de Icaza <miguel@ximian.com>
2192 * class.cs (EmitFieldInitializer): Use Assign expression to assign
2193 fields instead of rolling our own initializer. Takes care of all
2194 implicit conversions, and drops unnecessary static checks/argument.
2196 2002-03-31 Dick Porter <dick@ximian.com>
2198 * driver.cs: use the GetDirectories() return values properly, and
2199 use "/" as path separator.
2201 2002-03-30 Miguel de Icaza <miguel@ximian.com>
2203 * expression.cs (Unary): Optimize - - expr into expr.
2204 (Binary): Optimize a + (-b) into a -b.
2206 * codegen.cs (CodeGen): Made all methods static.
2208 2002-03-29 Miguel de Icaza <miguel@ximian.com>
2212 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
2213 TypeBuilder property.
2215 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
2218 * tree.cs: Removed the various RecordXXXX, and replaced with a
2219 single RecordDecl. Removed all the accessor methods, and just
2220 left a single access point Type
2222 * enum.cs: Rename DefineEnum to DefineType.
2224 * decl.cs: New abstract method `DefineType' used to unify the
2225 Defines for Enumerations, Interfaces, TypeContainers and
2228 (FindType): Moved LookupInterfaceOrClass here. Moved the
2229 LookupBaseClasses method that used to live in class.cs and
2230 interface.cs here, and renamed to FindType.
2232 * delegate.cs: Implement DefineType. Take advantage of the
2233 refactored pattern for locating the parent builder without taking
2234 the parent_builder argument (which we know does not work if we are
2235 nested, and triggering a toplevel definition).
2237 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2239 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
2240 accessibility of a member has changed during override and report
2243 * class.cs (Method.Define, Property.Define): Only complain on
2244 overrides if the method is private, any other accessibility is
2245 fine (and since we just checked the permission is the same, we are
2248 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
2249 and elif are processed always. The other pre-processing
2250 directives are only processed if we are "taking" the path
2252 2002-03-29 Martin Baulig <martin@gnome.org>
2254 * class.cs (Method.Emit): Only emit symbolic debugging info if the
2255 current location is not Null.
2257 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
2258 a separate method so we can profile it.
2260 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
2261 `span.Seconds' are just seconds, but no minutes or hours.
2262 (MainDriver): Profile the CodeGen.SaveSymbols calls.
2264 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2266 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
2267 Remove the gratuitous set of Final:
2269 // If an interface implementation, then we can set Final.
2270 if (((flags & MethodAttributes.Abstract) == 0) &&
2271 implementing.DeclaringType.IsInterface)
2272 flags |= MethodAttributes.Final;
2274 I do not know what I was smoking when I used that.
2277 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
2278 step into fixing the name resolution issues for delegates and
2279 unifying the toplevel name resolution.
2281 2002-03-28 Martin Baulig <martin@gnome.org>
2283 * class.cs (Method.Emit): If we have a symbol writer, call its
2284 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
2285 tell it about the current method.
2287 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
2288 writer that we're going to emit the first byte of IL code for a new
2289 statement (a new source line).
2290 (EmitContext.EmitTopBlock): If we have a symbol writer, call
2291 EmitContext.Mark() before emitting any code.
2293 * location.cs (SymbolDocument): Return null when we're Null.
2295 * statement.cs (Statement): Moved the `Location loc' variable here.
2296 (Statement.EmitBoolExpression): If we have a symbol writer, call
2297 ec.Mark() before emitting any code to tell it that we're at the
2298 beginning of a new statement.
2299 (StatementExpression): Added `Location' argument to the constructor.
2300 (Block): Added public readonly variable `StartLocation' and public
2301 variable `EndLocation'. The latter is to be set using SetEndLocation().
2302 (Block): Added constructor which takes a start and end location.
2303 (Block.SetEndLocation): New method. This sets the end location.
2304 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
2305 local variables we create.
2306 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
2307 each statement and do also mark the begin and end of the block.
2309 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
2310 tell it the current lexer.Location, use Location.Null for the end of the
2312 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
2313 current block, set its end location using SetEndLocation().
2314 (statement_expression): StatementExpression constructor now takes the
2315 lexer.Location as additional argument.
2316 (for_statement, declare_local_variables): Likewise.
2317 (declare_local_variables): When creating a new implicit block, use the
2318 new Block constructor and pass it the lexer.Location.
2320 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2322 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
2323 members also on the parent interfaces recursively.
2325 2002-03-27 Miguel de Icaza <miguel@ximian.com>
2327 * report.cs: Use new formats, since Gonzalo finished the missing
2330 * expression.cs (Binary.ResolveOperator): added missing operator|
2331 operator& and operator^ for bool/bool.
2333 * cs-parser.jay: CheckDef now takes a Location argument that is
2334 used to report errors more precisly (instead of reporting the end
2335 of a definition, we try to track something which is a lot closer
2336 to the source of the problem).
2338 * cs-tokenizer.cs: Track global token use, so we can properly flag
2339 the use of #define/#undef after the first token has been seen.
2341 Also, rename the reportXXXX to Error_DescriptiveName
2343 * decl.cs (DeclSpace.IsTopLevel): Move property here from
2344 TypeContainer, so that Enum and Interface can use this too.
2346 * class.cs (TypeContainer.LookupInterfaceOrClass,
2347 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
2348 `builder' argument. Typically this was used to pass the parent
2349 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
2352 The problem is that a nested class could trigger the definition of
2353 a toplevel class, and the builder would be obviously wrong in that
2356 So we drop this argument, and we compute dynamically the
2357 TypeBuilder/ModuleBuilder (the correct information was available
2358 to us anyways from DeclSpace.Parent)
2360 * interface.cs (Interface.DefineInterface): Drop builder
2361 parameter cleanup like class.cs
2363 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
2366 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
2369 (Try.Emit): Propagate the returns value from the statement.
2371 (Return.Emit): Even if we are leavning
2373 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
2375 * modifiers.cs: Fix the computation of MethodAttributes flags.
2377 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
2379 * driver.cs: allow compilation of files that start with '/'.
2380 Add a default case when checking the argument of --target.
2382 2002-03-25 Miguel de Icaza <miguel@ximian.com>
2384 * interface.cs: Implement the same search algorithm for types in
2387 * delegate.cs: Do not allow multiple definition.
2389 * Recovered ChangeLog that got accidentally amputated
2391 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
2393 * rootcontext.cs: Load manually enum to allow core classes to
2394 contain enumerations.
2396 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
2397 Update to new static methods in TypeManager.
2399 * typemanager.cs (GetMethod, GetConstructor): Use our
2400 implementation of FindMembers to find the members, since during
2401 corlib compilation, the types are TypeBuilders and GetMethod and
2402 GetConstructor do not work.
2404 Make all methods in TypeManager static.
2406 (InitCodeHelpers): Split the functionality from
2407 the InitCodeTypes function.
2409 * driver.cs: Call InitCodeHelpers after we have populated the
2412 * cs-parser.jay (delegate_declaration): we did not used to compute
2413 the delegate name correctly for void delegates.
2415 2002-03-24 Miguel de Icaza <miguel@ximian.com>
2417 * rootcontext.cs (RootContext): Init the interface_resolve_order
2418 and type_container_resolve_order always.
2420 (ResolveCore, BootstrapCorlib_ResolveClass,
2421 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
2422 compiler when compiling with --nostdlib
2424 * class.cs (TypeContainer.DefineType): Check that our parent is
2425 not null. This test is most important when we are bootstraping
2428 * codegen.cs: Split out the symbol writing code.
2430 2002-03-25 Martin Baulig <martin@gnome.org>
2432 * driver.cs (-g): Made -g an alias for --debug.
2434 2002-03-24 Martin Baulig <martin@gnome.org>
2436 * codegen.cs (SymbolWriter): New public variable. Returns the
2437 current symbol writer.
2438 (CodeGen): Added `bool want_debugging_support' argument to the
2439 constructor. If true, tell the ModuleBuild that we want debugging
2440 support and ask it for the ISymbolWriter.
2441 (Save): If we have a symbol writer, call it's Close() method after
2442 saving the assembly.
2444 * driver.c (--debug): New command line argument to create a
2445 debugger information file.
2447 * location.cs (SymbolDocument): New public property. Returns an
2448 ISymbolDocumentWriter object for the current source file or null
2449 if we don't have a symbol writer.
2451 2002-03-21 Miguel de Icaza <miguel@ximian.com>
2453 * driver.cs (LoadAssembly): Correctly return when all the paths
2454 have been tried and not before.
2456 * statement.cs (Switch.Emit): return the actual coverage for this
2457 statement (returns/not-returns)
2459 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
2460 switch of the statement if we are the last switch section. That
2461 kills two problems: try/catch problems (we used to emit an empty
2462 nop at the end) and switch statements where all branches would
2465 2002-03-19 Miguel de Icaza <miguel@ximian.com>
2467 * driver.cs: Add default assemblies (the equivalent to the
2468 Microsoft CSC.RSP file)
2470 * cs-tokenizer.cs: When updating `cols and setting it to zero,
2471 also update tokens_seen and set it to false.
2473 * driver.cs: Implement --recurse for Mike.
2475 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
2476 correctly splitting out the paths.
2478 2002-03-18 Miguel de Icaza <miguel@ximian.com>
2480 * interface.cs (Interface.PopulateProperty): Instead of using
2481 `parent' as the declaration space for the set parameters, use
2484 * support.cs (InternalParameters): InternalParameters constructor
2485 takes a DeclSpace instead of a TypeContainer.
2487 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
2488 types are being initialized, load the address of it before calling
2491 (New): Provide a mechanism to disable the generation of local
2492 value type temporaries when the caller will be providing us with
2493 an address to store it.
2495 (ArrayCreation.EmitDynamicInitializers): Use it.
2497 2002-03-17 Miguel de Icaza <miguel@ximian.com>
2499 * expression.cs (Invocation.EmitArguments): Only probe for array
2500 property if there is more than one argument. Sorry about that.
2502 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
2505 * class.cs (Method.LabelParameters): Fix incorrect code path that
2506 prevented the `ParamArrayAttribute' from being applied to the
2509 2002-03-16 Miguel de Icaza <miguel@ximian.com>
2511 * support.cs (ReflectionParameters): Correctly compute whether the
2512 last argument is a params array. Fixes the problem with
2515 * typemanager.cs: Make the assemblies array always be non-null
2516 (empty, but non-null)
2518 * tree.cs (RecordDecl): New function that abstracts the recording
2519 of names. This reports error 101, and provides a pointer to the
2520 previous declaration. Fixes a crash in the compiler.
2522 * cs-parser.jay (constructor_declaration): Update to new grammar,
2523 and provide a constructor_body that can be empty.
2525 2002-03-15 Miguel de Icaza <miguel@ximian.com>
2527 * driver.cs: Add support for --resources.
2529 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
2530 Make all types for the various array helper methods be integer.
2532 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
2533 CheckState to ConvCast.
2535 (ConvCast): Now it takes a `checked' state argument, to avoid
2536 depending on the emit context for the conversion, and just using
2537 the resolve time setting.
2539 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
2540 instead of Invocation.EmitArguments. We do not emit the original
2541 arguments, instead we emit those which have been converted to
2542 unsigned int expressions.
2544 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
2546 * codegen.cs: ditto.
2548 * expression.cs (LocalVariableReference): Drop the use of the
2549 Store function that depended on the variable index.
2551 * statement.cs (VariableInfo): Drop the `Idx' property from this
2552 class, as this is not taking into account the indexes for
2553 temporaries tat we generate during the execution, getting the
2556 * class.cs: First emit class initializers, then call the parent
2559 * expression.cs (Binary): Fix opcode emision.
2560 (UnaryMutator.EmitCode): Support checked code generation
2562 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
2563 matches for events for both the Static and Instance scans,
2564 pointing to the same element. Fix that.
2566 2002-03-14 Miguel de Icaza <miguel@ximian.com>
2568 * rootcontext.cs (ResolveTree): Always set the
2569 interface_resolve_order, because nested interfaces will be calling
2572 * class.cs (GetInterfaceOrClass): Track the same resolution
2573 process used by TypeManager.LookupType. This fixes the nested
2574 type lookups in class declarations (separate path from
2577 (TypeContainer.DefineType): Also define nested interfaces.
2578 (TypeContainer.RegisterOrder): New public function used to
2579 register the order in which child interfaces need to be closed.
2581 Nested interfaces need to be closed after their parents have been
2584 * interface.cs (InterfaceAttr): Put all the logic for computing
2585 the interface attribute here.
2587 (DefineInterface): Register our interface order with the
2588 RootContext or with the TypeContainer depending on the case.
2590 2002-03-12 Miguel de Icaza <miguel@ximian.com>
2592 * cs-parser.jay: rework foreach statement to work with the new
2593 changes to the policy on SimpleNames.
2595 * report.cs: support Stacktrace on warnings as well.
2597 * makefile: drop --unsafe and /unsafe from the compile.
2599 2002-03-13 Ravi Pratap <ravi@ximian.com>
2601 * ecore.cs (StandardConversionExists): Modify to take an Expression
2602 as the first parameter. Ensure we do null -> reference type conversion
2605 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
2606 temporary Expression objects.
2608 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
2610 * interface.cs: workaround bug in method overloading resolution
2611 (there is already a bugzilla bug for it).
2613 2002-03-12 Miguel de Icaza <miguel@ximian.com>
2615 We could also solve this problem by having a separate path for
2616 performing type lookups, instead of DoResolve, we could have a
2617 ResolveType entry point, and only participating pieces of the
2618 production (simplename, deref, array) would implement this.
2620 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
2621 signal SimpleName to only resolve type names and not attempt to
2622 resolve anything else.
2624 * expression.cs (Cast): Set the flag.
2626 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
2628 * class.cs: Only report 108 if there is no `new' modifier.
2630 * cs-parser.jay: rework foreach statement to work with the new
2631 changes to the policy on SimpleNames.
2633 * report.cs: support Stacktrace on warnings as well.
2635 * makefile: drop --unsafe and /unsafe from the compile.
2637 2002-03-11 Miguel de Icaza <miguel@ximian.com>
2639 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
2640 lookups here, instead of doing that at parse time. This means
2641 that our grammar will not introduce `LocalVariableReferences' as
2642 expressions at this point. That solves the problem of code like
2650 This is only half the fix. The full fix requires parameters to
2651 also be handled in this way.
2653 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
2654 makes the use more obvious of the DeclSpace. The
2655 ec.TypeContainer.TypeBuilder is now only used to pull the
2658 My theory is that I can get rid of the TypeBuilder completely from
2659 the EmitContext, and have typecasts where it is used (from
2660 DeclSpace to where it matters).
2662 The only pending problem is that the code that implements Aliases
2663 is on TypeContainer, and probably should go in DeclSpace.
2665 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
2666 lookups here, instead of doing that at parse time. This means
2667 that our grammar will not introduce `LocalVariableReferences' as
2668 expressions at this point. That solves the problem of code like
2676 This is only half the fix. The full fix requires parameters to
2677 also be handled in this way.
2679 * class.cs (Property.DefineMethod): When implementing an interface
2680 method, set newslot, when implementing an abstract method, do not
2681 set the flag (before we tried never setting it, or always setting
2682 it, which is the difference).
2683 (Indexer.DefineMethod): same.
2684 (Method.DefineMethod): same.
2686 * ecore.cs: Only set the status used flag if we get back a Field.
2688 * attribute.cs: Temporary hack, so Paolo can keep working.
2690 2002-03-08 Ravi Pratap <ravi@ximian.com>
2692 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
2693 the unmanaged type in the case we have a MarshalAs attribute.
2695 (Resolve): Handle the case when we are parsing the special MarshalAs
2696 attribute [we need to store the unmanaged type to use later]
2698 * typemanager.cs (marshal_as_attr_type): Built in type for the
2699 MarshalAs Attribute.
2701 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
2702 on parameters and accordingly set the marshalling info.
2704 2002-03-09 Miguel de Icaza <miguel@ximian.com>
2706 * class.cs: Optimizing slightly by removing redundant code after
2707 we switched to the `NoTypes' return value.
2708 (Property.DefineMethod): use NoTypes here too.
2710 This fixes the bug I introduced in my last batch of changes.
2712 2002-03-05 Ravi Pratap <ravi@ximian.com>
2714 * tree.cs (RecordEnum): Add. We now keep track of enums too.
2716 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
2717 Enums since those are types too.
2719 * cs-parser.jay (enum_declaration): Record enums as we parse them.
2721 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
2722 thanks to a call during the lookup process.
2724 2002-03-07 Miguel de Icaza <miguel@ximian.com>
2726 * statement.cs (Foreach): Lots of work to accomodate a particular
2727 kind of foreach statement that I had not kept in mind. It is
2728 possible to have foreachs on classes that provide a GetEnumerator
2729 method that return objects that implement the "pattern" for using
2730 a foreach, there is no need to support GetEnumerator
2733 This is needed to compile nant.
2735 * decl.cs: Only report 114 if the member is not `Finalize' and if
2736 the warning level is at least 2.
2738 * class.cs: Moved the compare function from Method to
2741 (MethodSignature.InheritableMemberSignatureCompare): Add new
2742 filter function that is used to extract inheritable methods from a
2745 (Method.Define): Use the new `inheritable_method_signature_filter'
2748 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
2751 2002-03-06 Miguel de Icaza <miguel@ximian.com>
2753 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
2755 * cs-parser.jay: Add opt_semicolon to the interface declaration.
2757 * expression.cs: Pass location information to
2758 ConvertImplicitStandard.
2760 * class.cs: Added debugging code to track return values from
2763 2002-03-05 Miguel de Icaza <miguel@ximian.com>
2765 * expression.cs (Is.DoResolve): If either side of the `is' is an
2766 interface, do not flag the warning.
2768 * ecore.cs (ImplicitReferenceConversion): We need a separate test
2771 * report.cs: Allow for --fatal to be used with --probe.
2773 * typemanager.cs (NoTypes): Move the definition for the empty Type
2776 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
2778 (TypeContainer.DefineProxy): New function used to proxy to parent
2779 implementations when implementing interfaces.
2780 (TypeContainer.ParentImplements): used to lookup if our parent
2781 implements a public function that is required by an interface.
2782 (TypeContainer.VerifyPendingMethods): Hook this up.
2784 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
2785 `modules' and `assemblies' arraylists into arrays. We only grow
2786 these are the very early start up of the program, so this improves
2787 the speedof LookupType (nicely measured).
2789 * expression.cs (MakeByteBlob): Replaced unsafe code with
2790 BitConverter, as suggested by Paolo.
2792 * cfold.cs (ConstantFold.Binary): Special case: perform constant
2793 folding of string concatenation, but if either side is a string,
2794 and the other is not, then return null, and let the runtime use
2795 the concatenation on the string plus the object (using
2798 2002-03-04 Miguel de Icaza <miguel@ximian.com>
2800 Constant Folding has been implemented now.
2802 * expression.cs (Unary.Reduce): Do not throw an exception, catch
2803 the error instead on types that are not supported in one's
2806 * constant.cs (Constant and all children): New set of functions to
2807 perform implict and explicit conversions.
2809 * ecore.cs (EnumConstant): Implement the new functions to perform
2810 conversion by proxying to the child expression.
2812 * codegen.cs: (ConstantCheckState): Constant evaluation has its
2813 own separate setting that can not be turned off from the command
2814 line using --unchecked or --checked and is only controlled using
2815 the checked/unchecked statements and expressions. This setting is
2816 used by the constant folder to flag errors.
2818 * expression.cs (CheckedExpr, UncheckedExpr): Set the
2819 ConstantCheckState as well.
2821 During Resolve, they also have to flag the state, because the
2822 constant folder runs completely in the Resolve phase.
2824 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
2827 2002-03-01 Miguel de Icaza <miguel@ximian.com>
2829 * cfold.cs: New file, this file contains the constant folder.
2831 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
2832 argument to track whether we are using the resulting address to
2833 load or store a value and provide better error messages.
2835 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
2836 new AddressOf arguments.
2838 * statement.cs (Foreach.EmitCollectionForeach): Update
2840 * expression.cs (Argument.Emit): Call AddressOf with proper
2841 arguments to track usage.
2843 (New.DoEmit): Call AddressOf with new arguments.
2845 (Unary.Emit): Adjust AddressOf call.
2847 2002-03-01 Ravi Pratap <ravi@ximian.com>
2849 * cs-parser.jay (member_access): Change the case for pre-defined types
2850 to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
2853 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
2856 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
2857 essentially like methods and apply attributes like MethodImplOptions to them too.
2859 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
2862 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
2863 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
2866 * Update code everywhere accordingly.
2868 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
2870 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
2872 2002-02-28 Ravi Pratap <ravi@ximian.com>
2874 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
2875 try performing lookups against those instead of jumping straight into using
2876 the 'using' clauses.
2878 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
2880 (LookupType): Perform lookups in implicit parents too.
2882 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
2883 sequence as RootContext.LookupType.
2885 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
2886 the various cases of namespace lookups into this method.
2888 2002-03-01 Miguel de Icaza <miguel@ximian.com>
2890 * cs-parser.jay: Add support for [Attribute ()] (empty arguments
2891 in positional arguments)
2893 * class.cs (Operator): Update the AllowedModifiers to contain
2896 * cs-parser.jay: Update operator declaration to allow for the
2897 operator body to be empty.
2899 * cs-tokenizer.cs: Added '\u' unicode support in strings and hex
2902 2002-02-27 Miguel de Icaza <miguel@ximian.com>
2904 * class.cs (Method.Emit): Label parameters.
2906 * driver.cs: Return 1 or 0 as the program exit code.
2908 2002-02-26 Miguel de Icaza <miguel@ximian.com>
2910 * expression.cs: Special case the `null' object when trying to
2911 auto-compute the type, as anything can be explicitly converted to
2914 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
2915 spotting this Paolo.
2917 (Expression.ImplicitNumericConversion): Perform comparissions of
2918 the type using the underlying type in the case of an enumeration
2919 rather than using the enumeration type for the compare.
2921 Cope with the underlying == type case, which is not possible to
2924 (Expression.ConvertNumericExplicit): Perform comparissions of
2925 the type using the underlying type in the case of an enumeration
2926 rather than using the enumeration type for the compare.
2928 * driver.cs: If the user does not supply an extension, assume .exe
2930 * cs-parser.jay (if_statement): Rewrote so that we can track the
2931 location for the if statement.
2933 * expression.cs (Binary.ConstantFold): Only concat strings when
2934 the operation is "+", not everything ;-)
2936 * statement.cs (Statement.EmitBoolExpression): Take a location
2938 (If, While, Do): Track location.
2940 * expression.cs (Binary.ResolveOperator): In the object + string
2941 case, I was missing a call to ConvertImplicit
2943 2002-02-25 Ravi Pratap <ravi@ximian.com>
2945 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
2946 Location arguments. Ensure we use RootContext.LookupType to do our work
2947 and not try to do a direct Type.GetType and ModuleBuilder.GetType
2949 * interface.cs (PopulateMethod): Handle the type of the parameter being
2952 * expression.cs (Invocation.BetterFunction): Handle the case when we
2953 have a params method with no fixed arguments and a call is made with no
2956 2002-02-25 Miguel de Icaza <miguel@ximian.com>
2958 * cs-tokenizer.cs: Add support for the quote-escape-sequence in
2959 the verbatim-string-literal
2961 * support.cs (InternalParameters.ParameterModifier): handle null
2963 (InternalParameters.ParameterType): ditto.
2965 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
2966 duplicating the name of the variable parameter.
2967 (GetParameterByName): Fix bug where we were not looking up array
2968 paramters if they were the only present (thanks Paolo!).
2969 (GetParameterInfo): We only have an empty set of types if both
2970 fixed and array are set to null.
2971 (GetParameterInfo-idx): Handle FixedParameter == null
2973 * cs-parser.jay: Handle the case where there is no catch
2974 statements (missing null test).
2976 2002-02-22 Miguel de Icaza <miguel@ximian.com>
2978 * driver.cs (MainDriver): Be conservative on our command line
2981 Catch DirectoryNotFoundException when calling GetFiles.
2983 (SplitPathAndPattern): Used to split the input specification into
2984 a path and a pattern that we can feed to Directory.GetFiles.
2986 2002-02-21 Miguel de Icaza <miguel@ximian.com>
2988 * statement.cs (Fixed): Implement the last case of the Fixed
2989 statement (string handling).
2991 * expression.cs (StringPtr): New class used to return a char * to
2992 a string; Used by the Fixed statement.
2994 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
2996 * expression.cs (Binary.ResolveOperator): Remove redundant
2997 MemberLookup pn parent type.
2998 Optimize union call, we do not need a union if the types are the same.
2999 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
3002 Specialize the use of MemberLookup everywhere, instead of using
3003 the default settings.
3005 (StackAlloc): Implement stackalloc keyword.
3007 * cs-parser.jay: Add rule to parse stackalloc.
3009 * driver.cs: Handle /h, /help, /?
3011 * expression.cs (MakeByteBlob): Removed the hacks we had in place
3012 before we supported unsafe code.
3014 * makefile: add --unsafe to the self compilation of mcs.
3016 2002-02-20 Miguel de Icaza <miguel@ximian.com>
3018 * expression.cs (PointerArithmetic): New class that is used to
3019 perform pointer arithmetic.
3020 (Binary.Resolve): Handle pointer arithmetic
3021 Handle pointer comparission.
3022 (ArrayPtr): Utility expression class that is used to take the
3023 address of an array.
3025 (ElementAccess): Implement array access for pointers
3027 * statement.cs (Fixed): Implement fixed statement for arrays, we
3028 are missing one more case before we are done.
3030 * expression.cs (Indirection): Implement EmitAssign and set the
3031 ExprClass to Variable. This allows pointer dereferences to be
3032 treated as variables, and to have values assigned to them.
3034 * ecore.cs (Expression.StoreFromPtr): New utility function to
3035 store values dereferencing.
3037 2002-02-20 Ravi Pratap <ravi@ximian.com>
3039 * expression.cs (Binary.ResolveOperator): Ensure that we are
3040 not trying to operate on a void type - this fixes the reported
3043 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
3044 the parent implementation is sealed.
3046 * ../errors/cs0239.cs : Add.
3048 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
3050 * typemanager.cs (unverifiable_code_type): Corresponds to
3051 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
3052 which have unsafe code in them.
3054 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
3057 2002-02-19 Miguel de Icaza <miguel@ximian.com>
3059 * cs-tokenizer.cs: Add support for @"litreal strings"
3061 Make tokenizer accept pre-processor directives
3062 on any column (remove the old C-like limitation).
3064 * rootcontext.cs (EmitCode): Emit any global attributes.
3065 (AddGlobalAttributes): Used to keep track of assembly attributes.
3067 * attribute.cs (ApplyAttributes): Support AssemblyAttributes.
3069 * cs-parser.jay: Add support for global attributes.
3071 2002-02-17 Miguel de Icaza <miguel@ximian.com>
3073 * expression.cs (Indirection): New helper class. Unary will
3074 create Indirection classes to be able to implement the
3075 IMemoryLocation interface on it.
3077 2002-02-16 Miguel de Icaza <miguel@ximian.com>
3079 * cs-parser.jay (fixed_statement): reference the right statement.
3081 * statement.cs (Fixed.Emit): Finish implementing the fixed
3082 statement for the &x case.
3084 2002-02-14 Miguel de Icaza <miguel@ximian.com>
3086 * class.cs (Property.Define, Method.Define): Remove newslot when
3089 * modifiers.cs: My use of NewSlot when `Abstract' was set was
3090 wrong. NewSlot should only be used if the `new' keyword is present.
3092 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
3093 locating our system dir. Sorry about this.
3095 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3097 * driver.cs (GetSystemDir): Compute correctly the location of our
3098 system assemblies. I was using the compiler directory instead of
3099 the library directory.
3101 2002-02-13 Ravi Pratap <ravi@ximian.com>
3103 * expression.cs (BetterFunction): Put back in what Miguel commented out
3104 since it is the correct fix. The problem is elsewhere ;-)
3106 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
3107 parameters of the parms method are themselves compatible or not !
3109 (StandardConversionExists): Fix very dangerous bug where we were forgetting
3110 to check that a class implements an interface before saying that an implicit
3111 conversion was allowed. Use ImplementsInterface to do the checking.
3113 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3115 * class.cs (Method.Define): Track whether we are an explicit
3116 implementation or not. And only call DefineMethodOverride if we
3117 are an explicit implementation.
3119 (Property.DefineMethod): Ditto.
3121 2002-02-11 Ravi Pratap <ravi@ximian.com>
3123 * expression.cs (BetterFunction): Catch hideous bug which was
3124 preventing us from detecting ambiguous calls due to implicit casts i.e
3127 2002-01-29 Miguel de Icaza <miguel@ximian.com>
3129 * support.cs (Pair): Remove un-needed method. I figured why I was
3130 getting the error in cs-parser.jay, the variable in a foreach loop
3131 is readonly, and the compiler does not really treat this as a variable.
3133 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
3134 instead of EQUALS in grammar.
3136 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
3138 * expression.cs (Unary.DoResolve): Check whether the argument is
3141 2002-01-28 Miguel de Icaza <miguel@ximian.com>
3143 * support.cs: Api for Pair to set a value. Despite the fact that
3144 the variables are public the MS C# compiler refuses to compile
3145 code that accesses the field if the variable is part of a foreach
3148 * statement.cs (Fixed): Begin implementation of the fixed
3151 (Block.AddVariable): Return the VariableInfo on success and null
3152 on failure instead of true/false.
3154 * cs-parser.jay (foreach): Catch errors on variables already
3155 defined (we were ignoring this value before) and properly unwind
3158 (fixed_statement): grammar for the fixed statement.
3160 2002-01-25 Miguel de Icaza <miguel@ximian.com>
3162 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
3163 pointer types to be incretemented.
3165 (SizeOf): Implement.
3167 * cs-parser.jay (pointer_member_access): Implement
3168 expr->IDENTIFIER production.
3170 * expression.cs (IndexerAccess.DoResolve, ArrayAccess.DoResolve,
3171 MemberAccess.DoResolve, Invocation.DoResolve): Check for pointers
3174 (Unary): Implement indirection.
3176 * ecore.cs (Expression.UnsafeError): Reports error 214 (pointer
3177 use in non-unsafe context).
3179 (SimpleName.DoResolve): Check for pointers in field access on safe
3182 (Expression.LoadFromPtr): Factor the load-indirect code in this
3183 function. This was duplicated in UnboxCast and ParameterReference
3185 2002-01-24 Miguel de Icaza <miguel@ximian.com>
3187 * expression.cs (ComposedCast): report an error if a pointer cast
3188 is used in a safe region.
3190 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
3191 pointer type casts in unsafe context.
3193 * codegen.cs (EmitContext): Set up IsUnsafe.
3195 * cs-parser.jay (non_expression_type): Add productions for pointer
3198 * expression.cs (Invocation.EmitCall): Remove chunk of buggy
3199 code. We should not use force into static mode if the method is
3200 not virtual. Fixes bug in MIS
3202 * statement.cs (Do.Emit, While.Emit, For.Emit,
3203 Statement.EmitBoolExpression): Add support to Do and While to
3204 propagate infinite loop as `I do return' semantics.
3206 Improve the For case to also test for boolean constants.
3208 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
3209 to the list of attributes we can add.
3211 Remove `EmitContext' argument.
3213 * class.cs (Method.Define): Apply parameter attributes.
3214 (Constructor.Define): Apply parameter attributes.
3215 (MethodCore.LabelParameters): Move here the core of labeling
3218 * support.cs (ReflectionParameters.ParameterModifier,
3219 InternalParameters.ParameterModifier): Use IsByRef on the type and
3220 only return the OUT bit for these parameters instead of in/out/ref
3223 This is because I miss-understood things. The ParameterInfo.IsIn
3224 and IsOut represent whether the parameter has the [In] and [Out]
3227 2002-01-22 Miguel de Icaza <miguel@ximian.com>
3229 * ecore.cs (FieldExpr.Emit): Release temporaries.
3231 * assign.cs (LocalTemporary.Release): new function.
3233 * codegen.cs (EmitContext.GetTemporaryStorage,
3234 EmitContext.FreeTemporaryStorage): Rework the way we deal with
3235 temporary storage. Now we can "put back" localbuilders when we
3238 2002-01-21 Miguel de Icaza <miguel@ximian.com>
3240 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
3241 need to make a copy of the variable to generate verifiable code.
3243 2002-01-19 Miguel de Icaza <miguel@ximian.com>
3245 * driver.cs: Compute dynamically the system directory.
3247 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
3248 Slower, but more generally useful. Used by the abstract
3249 registering implementation.
3251 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
3252 the rules for the special rule on Type/instances. First check if
3253 we have the same name, and if so, try that special static path
3254 rather than the instance path.
3256 2002-01-18 Miguel de Icaza <miguel@ximian.com>
3258 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
3261 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
3262 Enum, ValueType, Delegate or Array for non-corlib compiles.
3264 * cs-tokenizer.cs: Catch long identifiers (645)
3266 * typemanager.cs (IndexerPropetyName): Ravi never tested this
3269 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
3270 fix, we were returning too early, so we were not registering
3271 pending methods from abstract classes.
3273 Do not register pending methods if the class is abstract.
3275 * expression.cs (Conditional.DoResolve): Report circular implicit
3276 conversions when we neecd to compute it for conditional
3279 (Is.DoResolve): If the expression is always of the provided type,
3280 flag warning 183. If the expression can not ever be of the
3281 provided type flag warning 184.
3283 * class.cs: Catch 169 as well.
3285 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
3288 2002-01-18 Nick Drochak <ndrochak@gol.com>
3290 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.
3292 2002-01-17 Miguel de Icaza <miguel@ximian.com>
3294 * interface.cs: (PopulateMethod): Check for pointers being defined
3295 only if the unsafe context is active.
3296 (PopulateProperty): ditto.
3297 (PopulateIndexer): ditto.
3299 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
3300 specified. If pointers are present, make sure that they are
3301 present in an unsafe context.
3302 (Constructor, Constructor.Define): ditto.
3303 (Field, Field.Define): ditto.
3304 (Property, Property.Define): ditto.
3305 (Event, Event.Define): ditto.
3307 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
3308 hashtable if there are classes or structs defined.
3310 * expression.cs (LocalVariableReference.DoResolve): Simplify this
3311 code, as the constant resolution moved.
3313 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
3314 the metadata, so we can flag error 133.
3316 * decl.cs (MemberCore.UnsafeOK): New function to test that a
3317 pointer is being declared in an unsafe context.
3319 2002-01-16 Miguel de Icaza <miguel@ximian.com>
3321 * modifiers.cs (Modifiers.Check): Require a Location argument.
3322 Report error 227 for Unsafe use.
3324 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
3326 * statement.cs (For.Emit): If the test is null, then report that
3327 we do `return', as we wont reach anything afterwards.
3329 (Switch.SwitchGoverningType): Track the expression that matched
3332 * driver.cs: Allow negative numbers as an error code to flag.
3334 * cs-parser.jay: Handle 1551.
3336 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
3338 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3340 * cs-parser.jay: Report 1518 (type declaration can only contain
3341 class, struct, interface, enum or delegate)
3343 (switch_label): Report 1523 (keywords `case' or `default' must
3346 (opt_switch_sections): Report 1522 (empty switch)
3348 * driver.cs: Report 1515 (response file specified multiple times)
3349 Report 1516 (Source file specified multiple times).
3351 * expression.cs (Argument.Resolve): Signal 1510
3353 (BaseAccess.Resolve, BaseIndexer.Resolve): Signal 1511 (base
3354 access not allowed in static code)
3356 2002-01-11 Ravi Pratap <ravi@ximian.com>
3358 * typemanager.cs (IsPointerType): Utility method which we are going
3361 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
3362 the object type, so we take care of that.
3364 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
3366 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
3367 added to non-params parameters :-)
3369 * typemanager.cs (CSharpName): Include 'void' type too.
3371 (void_ptr_type): Include in the set of core types.
3373 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
3376 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
3379 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
3380 completely forgotten about it.
3382 2002-01-10 Ravi Pratap <ravi@ximian.com>
3384 * cs-parser.jay (pointer_type): Add. This begins our implementation
3385 of parsing rules for unsafe code.
3387 (unsafe_statement): Implement.
3389 (embedded_statement): Modify to include the above.
3391 * statement.cs (Unsafe): Implement new class for unsafe blocks.
3393 * codegen.cs (EmitContext.InUnsafe): Add. This determines
3394 if the current context is an unsafe one.
3396 * cs-parser.jay (local_variable_pointer_type): Since local variable types
3397 are handled differently, we need separate rules for them.
3399 (local_variable_declaration): Update to use local_variable_pointer_type
3400 to allow variable declarations of unmanaged pointer types.
3402 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
3405 * ../errors/cs0214.cs : Add.
3407 2002-01-16 Nick Drochak <ndrochak@gol.com>
3409 * makefile: remove 'response' file when cleaning.
3411 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3413 * cs-parser.jay: Report 1524.
3415 2002-01-14 Miguel de Icaza <miguel@ximian.com>
3417 * typemanager.cs (RegisterMethod): drop checking if we have
3418 registered this from here
3420 2002-01-12 Miguel de Icaza <miguel@ximian.com>
3422 * class.cs (Method.EmitDestructor): Implement calling our base
3425 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
3428 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
3429 this routine and will wrap the call in a try/catch block. Deal
3432 2002-01-11 Miguel de Icaza <miguel@ximian.com>
3434 * ecore.cs (Expression.MemberLookup): instead of taking a
3435 parameter `same_type' that was used to tell whether we could
3436 access private members we compute our containing type from the
3439 (FieldExpr): Added partial support for volatile fields. This does
3440 not work for volatile fields exposed from assemblies, as I can not
3441 figure out how to extract the modreq from it.
3443 Updated all the source files to use this.
3445 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
3446 because it is referenced by MemberLookup very often.
3448 2002-01-09 Ravi Pratap <ravi@ximian.com>
3450 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
3451 TypeBuilder.GetCustomAttributes to retrieve what we need.
3453 Get rid of redundant default_member_attr_type as this is the same as
3454 default_member_type which already exists.
3456 * interface.cs, attribute.cs : Update accordingly.
3458 2002-01-08 Miguel de Icaza <miguel@ximian.com>
3460 * typemanager.cs: Enable IndexerPropertyName again. It does not
3461 work for TYpeBuilders though. Ravi, can you please fix this?
3463 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
3465 * expression.cs (Argument.Emit): Handle the case of ref objects
3466 being passed to ref functions;
3468 (ParameterReference.EmitLoad): Loads the content of the pointer
3469 without dereferencing.
3471 2002-01-07 Miguel de Icaza <miguel@ximian.com>
3473 * cs-tokenizer.cs: Implemented the pre-processing expressions.
3475 2002-01-08 Ravi Pratap <ravi@ximian.com>
3477 * class.cs (Indexer.DefineMethod): Incorporate the interface
3478 type in the name of the method if we are doing explicit interface
3481 * expression.cs (ConversionExists): Remove as it is completely obsolete.
3483 (BetterConversion): Fix extremely trivial bug where we were referring to
3484 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
3487 * ../errors/bug16.cs : Add although we have fixed it.
3489 2002-01-07 Miguel de Icaza <miguel@ximian.com>
3491 * expression.cs (BaseIndexer): Begin implementation.
3493 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
3495 * cs-parser.jay (indexer_declarator): Use qualified_identifier
3496 production directly to remove a shift/reduce, and implement
3497 explicit interface implementation.
3499 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
3500 after a floating point suffix.
3502 * expression.cs (DoNumericPromotions): Improved the conversion for
3503 uint/uint. If we have a constant, we avoid doing a typecast to a
3506 * class.cs (Indexer): Implement explicit interface implementation
3509 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
3511 * class.cs: make the default instance constructor public and hidebysig.
3513 2001-01-03 Ravi Pratap <ravi@ximian.com>
3515 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
3516 so we can call it from elsewhere.
3518 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
3519 we emit it internally if the class has a defined indexer; otherwise the user
3520 emits it by decorating the class definition with the DefaultMemberAttribute.
3522 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
3523 attribute is not used on a type which defines an indexer.
3525 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
3526 character when we skip whitespace.
3528 * ../errors/cs0646.cs : Add.
3530 2002-01-03 Miguel de Icaza <miguel@ximian.com>
3532 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
3535 * makefile: Add practical target `mcs3.exe' which builds the third
3536 generation compiler.
3538 * expression.cs (New): Fix structures constructor calling.
3540 * class.cs (Property, Method, Indexer): Emit Final flag on the
3541 method if we are an interface implementation and we are not
3544 * ecore.cs (PropertyExpr): New public field `IsBase', tells
3545 whether this property is referencing a `base' method.
3547 * expression.cs (Invocation.EmitCall): take an extra argument:
3548 is_base, this is used to determine whether the `call' or
3549 `callvirt' opcode should be used.
3552 * delegate.cs: update EmitCall.
3554 * class.cs (Method.Define): Set NewSlot for the cases where we are
3555 not implementing an interface method.
3557 (Property.Define): ditto.
3559 2002-01-02 Miguel de Icaza <miguel@ximian.com>
3561 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
3562 'r'. Allows mcs to parse itself fully.
3564 2002-01-02 Ravi Pratap <ravi@ximian.com>
3566 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
3567 of the number of initializers that require the InitializeArray method.
3569 (CheckIndices): Store the Expression in all cases - not the plain value. Also
3570 update the above field where necessary.
3572 (MakeByteBlob): Update accordingly.
3574 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
3577 (EmitDynamicInitializers): Update in accordance with the new optimization.
3579 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
3580 same OpCode applies.
3582 * cs-parser.jay : Fix some glaring errors I introduced.
3584 2002-01-01 Ravi Pratap <ravi@ximian.com>
3586 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
3587 so that we can check for name clashes there too.
3589 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
3590 for interface indexers.
3592 * interfaces.cs (Define): Emit the default member attribute.
3594 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
3595 variable was being referred to while setting the value ;-)
3597 2002-01-01 Miguel de Icaza <miguel@ximian.com>
3599 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
3600 byte-by-byte information when we know the data is zero.
3602 Make the block always a multiple of 4, because
3603 DefineInitializedData has a bug.
3605 * assign.cs: Fix, we should assign from the temporary, not from
3608 * expression.cs (MakeByteBlob): Fix my incorrect code.
3610 2001-12-31 Miguel de Icaza <miguel@ximian.com>
3612 * typemanager.cs (EnumToUnderlying): This function is used to get
3613 the underlying type from an enumeration, because it does not
3616 * constant.cs: Use the I4_S form for values between -128 and 127.
3618 * statement.cs (Block.LookupLabel): Looks up a label.
3619 (Block): Drop support for labeled blocks.
3621 (LabeledStatement): New kind of statement that represents a label
3624 (Goto): Finally implement this bad boy.
3626 * cs-parser.jay: Update to reflect new mechanism to implement
3629 2001-12-30 Miguel de Icaza <miguel@ximian.com>
3631 * codegen.cs (EmitContext.This): a codegen property that keeps the
3632 a single instance of this instead of creating many different this
3635 * delegate.cs (Delegate.DoResolve): Update to use the property;
3637 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
3639 * expression.cs (BaseAccess.DoResolve): Ditto.
3641 2001-12-29 Ravi Pratap <ravi@ximian.com>
3643 * typemanager.cs (methodimpl_attr_type): Add to hold the type
3644 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
3646 (InitCoreTypes): Update accordingly.
3648 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
3649 so we can quickly store the state.
3651 (ApplyAttributes): Set the correct implementation flags
3652 for InternalCall methods.
3654 2001-12-29 Miguel de Icaza <miguel@ximian.com>
3656 * expression.cs (EmitCall): if a method is not virtual, then do
3657 not use callvirt on it.
3659 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
3660 user defined stuff) requires the use of stobj, which takes an
3661 address on the stack instead of an array and an index. So emit
3662 the Ldelema operation for it.
3664 (EmitStoreOpcode): Use stobj for valuetypes.
3666 (UnaryMutator.EmitCode): Use the right 1 value depending on
3667 whether we are dealing with int64/uint64, float or doubles.
3669 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
3670 constructors that I implemented last night.
3672 (Constructor.IsDefault): Fix to work properly for static
3675 * cs-parser.jay (CheckDef): report method signature errors.
3676 Update error number 103 to be 132.
3678 * decl.cs: New AdditionResult enumeration value: MethodExists.
3679 Although we do this check for methods later on in the semantic
3680 analysis, catching repeated default constructors is so easy that
3681 we catch these here.
3683 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
3686 (ParameterReference.EmitAssign, Emit): handle
3689 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
3690 (ArrayAccess.EmitStoreOpcode): ditto.
3692 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
3694 * expression.cs (MakeByteBlob): Complete all the missing types
3695 (uint, short, ushort, byte, sbyte)
3697 * class.cs: Only init instance field initializers on instance
3700 Rename `constructors' to instance_constructors.
3702 (TypeContainer.AddConstructor): Only add constructors to the list
3703 if it is not static.
3705 Make sure that we handle default_static_constructor independently
3706 everywhere where we handle instance_constructors
3708 2001-12-28 Miguel de Icaza <miguel@ximian.com>
3710 * class.cs: Do not lookup or create a base initializer for a
3713 (ConstructorInitializer.Resolve): use the proper type to lookup
3716 * cs-parser.jay: Report error 1585 (modifiers between type and name).
3718 * enum.cs, interface.cs: Remove CloseType, this is taken care by
3721 * decl.cs: CloseType is now an virtual method, the default
3722 implementation just closes this type.
3724 2001-12-28 Ravi Pratap <ravi@ximian.com>
3726 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
3727 to PreserveSig by default. Also emit HideBySig on such methods.
3729 Basically, set the defaults to standard values.
3731 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
3732 argument, if candidate is better, it can't be worse than the best !
3734 (Invocation): Re-write bits to differentiate between methods being
3735 applicable in their expanded form and their normal form - for params
3738 Get rid of use_standard everywhere as only standard conversions are allowed
3739 in overload resolution.
3741 More spec conformance.
3743 2001-12-27 Miguel de Icaza <miguel@ximian.com>
3745 * driver.cs: Add --timestamp, to see where the compiler spends
3748 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
3749 `this' in static code.
3751 (SimpleName.DoResolve): Implement in terms of a helper function
3752 that allows static-references to be passed upstream to
3755 (Expression.ResolveWithSimpleName): Resolve specially simple
3756 names when called by MemberAccess to implement the special
3759 (Expression.ImplicitReferenceConversion): Handle conversions from
3760 Null to reference types before others, as Null's type is
3763 * expression.cs (Invocation.EmitCall): Handle the special case of
3764 calling methods declared on a reference type from a ValueType
3765 (Base classes System.Object and System.Enum)
3767 (MemberAccess.Resolve): Only perform lookups on Enumerations if
3768 the left hand side is a TypeExpr, not on every enumeration.
3770 (Binary.Resolve): If types are reference types, then do a cast to
3771 object on operators != and == of both arguments.
3773 * typemanager.cs (FindMembers): Extract instance and static
3774 members if requested.
3776 * interface.cs (PopulateProperty): Use void_type instead of null
3777 as the return type for the setter method.
3779 (PopulateIndexer): ditto.
3781 2001-12-27 Ravi Pratap <ravi@ximian.com>
3783 * support.cs (ReflectionParameters): Fix minor bug where we
3784 were examining the wrong parameter for the ParamArray attribute.
3786 Cope with requests for the type of the parameter at position
3787 greater than the params parameter's. We now return the element
3788 type of the params array as that makes more sense.
3790 * expression.cs (Invocation.IsParamsMethodApplicable): Update
3791 accordingly as we no longer have to extract the element type
3794 (Invocation.OverloadResolve): Update.
3796 2001-12-27 Miguel de Icaza <miguel@ximian.com>
3798 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
3799 against IEnumerator, test whether the return value is a descendant
3800 of the IEnumerator interface.
3802 * class.cs (Indexer.Define): Use an auxiliary method to implement
3803 the other bits of the method definition. Begin support for
3804 explicit interface implementation.
3806 (Property.DefineMethod): Use TypeManager.void_type instead of null
3807 for an empty return value.
3809 2001-12-26 Miguel de Icaza <miguel@ximian.com>
3811 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
3812 dealing with a FieldExpr which is composed of a FieldBuilder, in
3813 the code path we did extract the constant, but we should have
3814 obtained the underlying value to be able to cast it (otherwise we
3815 end up in an infinite loop, this is what Ravi was running into).
3817 (ArrayCreation.UpdateIndices): Arrays might be empty.
3819 (MemberAccess.ResolveMemberAccess): Add support for section
3820 14.5.4.1 that deals with the special case of E.I when E is a type
3821 and something else, that I can be a reference to a static member.
3823 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
3824 handle a particular array type to create byte blobs, it is just
3825 something we dont generate byteblobs for.
3827 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
3830 * location.cs (Push): remove the key from the hashtable that we
3831 are about to add. This happens for empty files.
3833 * driver.cs: Dispose files after we have parsed them.
3835 (tokenize): new function that only runs the tokenizer on its
3836 input, for speed testing.
3838 2001-12-26 Ravi Pratap <ravi@ximian.com>
3840 * class.cs (Event.Define): Define the private field only if there
3841 are no accessors defined.
3843 * expression.cs (ResolveMemberAccess): If there is no associated
3844 field with the event, that means we have an event defined with its
3845 own accessors and we should flag error cs0070 since transforming
3846 ourselves into a field is not valid in that case.
3848 * ecore.cs (SimpleName.DoResolve): Same as above.
3850 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
3851 and charset to sane values.
3853 2001-12-25 Ravi Pratap <ravi@ximian.com>
3855 * assign.cs (DoResolve): Perform check on events only if they
3856 are being accessed outside the declaring type.
3858 * cs-parser.jay (event_declarations): Update rules to correctly
3859 set the type of the implicit parameter etc.
3861 (add_accessor, remove_accessor): Set current local parameters.
3863 * expression.cs (Binary): For delegate addition and subtraction,
3864 cast the return value from the method into the appropriate delegate
3867 2001-12-24 Ravi Pratap <ravi@ximian.com>
3869 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
3870 of these as the workaround is unnecessary.
3872 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
3873 delegate data - none of that is needed at all.
3875 Re-write bits to extract the instance expression and the delegate method
3878 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
3881 * attribute.cs (ApplyAttributes): New method to take care of common tasks
3882 of attaching attributes instead of duplicating code everywhere.
3884 * everywhere : Update code to do attribute emission using the above method.
3886 2001-12-23 Miguel de Icaza <miguel@ximian.com>
3888 * expression.cs (IsParamsMethodApplicable): if there are not
3889 parameters, return immediately.
3891 * ecore.cs: The 0 literal can be implicity converted to an enum
3894 (SimpleName.DoResolve): First lookup the type, then lookup the
3897 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
3898 want to get its address. If the InstanceExpression is not
3899 addressable, store the result in a temporary variable, then get
3902 * codegen.cs: Only display 219 errors on warning level or above.
3904 * expression.cs (ArrayAccess): Make it implement the
3905 IMemoryLocation interface.
3907 (Binary.DoResolve): handle the operator == (object a, object b)
3908 and operator != (object a, object b) without incurring into a
3909 BoxedCast (because 5 != o should never be performed).
3911 Handle binary enumerator operators.
3913 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
3914 value type, otherwise use Ldelem_ref.
3916 Use precomputed names;
3918 (AddressOf): Implement address of
3920 * cs-parser.jay (labeled_statement): Fix recursive block
3921 addition by reworking the production.
3923 * expression.cs (New.DoEmit): New has a special case:
3925 If we are dealing with a ValueType, we have a few
3926 situations to deal with:
3928 * The target of New is a ValueType variable, that is
3929 easy, we just pass this as the variable reference
3931 * The target of New is being passed as an argument,
3932 to a boxing operation or a function that takes a
3935 In this case, we need to create a temporary variable
3936 that is the argument of New.
3939 2001-12-23 Ravi Pratap <ravi@ximian.com>
3941 * rootcontext.cs (LookupType): Check that current_type is not null before
3942 going about looking at nested types.
3944 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
3945 not implement the IAssignMethod interface any more.
3947 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
3948 where we tranform them into FieldExprs if they are being resolved from within
3951 * ecore.cs (SimpleName.DoResolve): Do the same here.
3953 * assign.cs (DoResolve, Emit): Clean up code considerably.
3955 * ../errors/bug10.cs : Add.
3957 * ../errors/cs0070.cs : Add.
3959 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
3961 * assign.cs : Get rid of EventIsLocal everywhere.
3963 2001-12-23 Miguel de Icaza <miguel@ximian.com>
3965 * ecore.cs (ConvertIntLiteral): finished the implementation.
3967 * statement.cs (SwitchLabel): Convert the value we are using as a
3968 key before looking up the table.
3970 2001-12-22 Miguel de Icaza <miguel@ximian.com>
3972 * codegen.cs (EmitTopBlock): Require a Location argument now.
3974 * cs-parser.jay (constructor_declarator): We need to setup
3975 current_local_parameters before we parse the
3976 opt_constructor_initializer, to allow the variables to be bound
3977 to the constructor arguments.
3979 * rootcontext.cs (LookupType): First lookup nested classes in our
3980 class and our parents before we go looking outside our class.
3982 * expression.cs (ConstantFold): Extract/debox the values at the
3985 * rootcontext.cs (EmitCode): Resolve the constants first before we
3986 resolve the types. This is not really needed, but it helps debugging.
3988 * statement.cs: report location.
3990 * cs-parser.jay: pass location to throw statement.
3992 * driver.cs: Small bug fix.
3994 * report.cs: Updated format to be 4-zero filled digits.
3996 2001-12-22 Ravi Pratap <ravi@ximian.com>
3998 * expression.cs (CheckIndices): Fix minor bug where the wrong
3999 variable was being referred to ;-)
4001 (DoEmit): Do not call EmitStaticInitializers when the
4002 underlying type is System.Object.
4004 2001-12-21 Ravi Pratap <ravi@ximian.com>
4006 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
4007 and do the usual workaround for SRE.
4009 * class.cs (MyEventBuilder.EventType): New member to get at the type
4010 of the event, quickly.
4012 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
4014 * assign.cs (Assign.DoResolve): Handle the case when the target
4015 is an EventExpr and perform the necessary checks.
4017 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
4020 (SimpleName.MemberStaticCheck): Include check for EventExpr.
4022 (EventExpr): Set the type in the constructor itself since we
4023 are meant to be born fully resolved.
4025 (EventExpr.Define): Revert code I wrote earlier.
4027 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
4028 instance expression is null. The instance expression is a This in that case
4029 or a null, depending on whether it is a static method or not.
4031 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
4032 refers to more than one method.
4034 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
4035 and accordingly flag errors.
4037 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4039 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
4041 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4043 * location.cs (ToString): Provide useful rutine.
4045 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4047 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
4048 objects, return the actual integral boxed.
4050 * statement.cs (SwitchLabel): define an ILLabel for each
4053 (Switch.CheckSwitch): If the value is a Literal, extract
4054 the underlying literal.
4056 Also in the unused hashtable we had, add the SwitchLabel so we can
4057 quickly look this value up.
4059 * constant.cs: Implement a bunch of new constants. Rewrite
4060 Literal based on this. Made changes everywhere to adapt to this.
4062 * expression.cs (Expression.MakeByteBlob): Optimize routine by
4063 dereferencing array only once, and also copes with enumrations.
4065 bytes are two bytes wide, not one.
4067 (Cast): Perform constant conversions.
4069 * ecore.cs (TryImplicitIntConversion): Return literals instead of
4070 wrappers to the literals here.
4072 * expression.cs (DoNumericPromotions): long literals can converted
4073 to ulong implicity (this is taken care of elsewhere, but I was
4076 * ecore.cs (Expression.Literalize): Make the return type Literal,
4077 to improve type checking.
4079 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
4081 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4083 * literal.cs: Revert code from ravi that checked the bounds. The
4084 bounds are sane by the definition of the type itself.
4086 * typemanager.cs: Fix implementation of ImplementsInterface. We
4087 need to actually look up in our parent hierarchy for interfaces
4090 * const.cs: Use the underlying type for enumerations
4092 * delegate.cs: Compute the basename for the delegate creation,
4093 that should fix the delegate test case, and restore the correct
4094 Type Lookup semantics in rootcontext
4096 * rootcontext.cs: Revert Ravi's last patch. The correct way of
4097 referencing a nested type with the Reflection API is using the "+"
4100 * cs-parser.jay: Do not require EOF token at the end.
4102 2001-12-20 Ravi Pratap <ravi@ximian.com>
4104 * rootcontext.cs (LookupType): Concatenate type names with
4105 a '.' instead of a '+' The test suite passes again.
4107 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
4108 field of the enumeration.
4110 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
4111 the case when the member is an EventExpr.
4113 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
4114 static has an associated instance expression.
4116 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
4118 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
4120 * class.cs (Event.Define): Register event and perform appropriate checks
4123 We define the Add and Remove methods even if the use provides none because
4124 in that case, we provide default implementations ourselves.
4126 Define a private field of the type of the event. This is done by the CSC compiler
4127 and we should be doing it too ;-)
4129 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
4130 More methods we use in code we generate.
4132 (multicast_delegate_type, delegate_type): Two separate types since the distinction
4135 (InitCoreTypes): Update accordingly for the above.
4137 * class.cs (Event.Emit): Generate code for default accessors that we provide
4139 (EmitDefaultMethod): Do the job in the above.
4141 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
4144 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4146 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
4147 builders even if we were missing one.
4149 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
4150 pass the Basename as our class name instead of the Name. The
4151 basename will be correctly composed for us.
4153 * parameter.cs (Paramters): Now takes a Location argument.
4155 * decl.cs (DeclSpace.LookupType): Removed convenience function and
4156 make all the code call directly LookupType in RootContext and take
4157 this chance to pass the Location information everywhere.
4159 * Everywhere: pass Location information.
4161 2001-12-19 Miguel de Icaza <miguel@ximian.com>
4163 * class.cs (Constructor.Define): Updated way of detecting the
4164 length of the parameters.
4166 (TypeContainer.DefineType): Use basename as the type name for
4169 (TypeContainer.Define): Do not recursively define types here, as
4170 definition is taken care in order by the RootContext.
4172 * tree.cs: Keep track of namespaces in a per-file basis.
4174 * parameter.cs (Parameter.ComputeSignature): Update to use
4177 (Parameters.GetSignature): ditto.
4179 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
4180 instead of a TypeContainer.
4182 (Interface.SemanticAnalysis): Use `this' instead of our parent to
4183 resolve names. Because we need to be resolve in our context, not
4186 * driver.cs: Implement response files.
4188 * class.cs (TypeContainer.DefineType): If we are defined, do not
4191 (Event.Emit): Emit the code for add/remove handlers.
4192 (Event.Define): Save the MethodBuilders for add/remove.
4194 * typemanager.cs: Use pair here too.
4196 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
4197 DictionaryEntry requires the first argument to be non-null.
4199 (enum_declaration): Compute full name for registering the
4202 (delegate_declaration): Instead of using
4203 formal_parameter_list, use opt_formal_parameter_list as the list
4206 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
4207 (EventParsing): New property that controls whether `add' and
4208 `remove' are returned as tokens or identifiers (for events);
4210 2001-12-19 Ravi Pratap <ravi@ximian.com>
4212 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
4213 use MyEventBuilder only and let it wrap the real builder for us.
4215 (MyEventBuilder): Revamp constructor etc.
4217 Implement all operations that we perform on EventBuilder in precisely the same
4220 (FindMembers): Update to use the EventBuilder member.
4222 (Event.Emit): Update accordingly.
4224 2001-12-18 Ravi Pratap <ravi@ximian.com>
4226 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
4227 by calling the appropriate methods.
4229 (GetCustomAttributes): Make stubs as they cannot possibly do anything
4232 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
4234 2001-12-17 Ravi Pratap <ravi@ximian.com>
4236 * delegate.cs (Delegate.Populate): Check that the return type
4237 and various parameters types are indeed accessible.
4239 * class.cs (Constructor.Define): Same here.
4241 (Field.Define): Ditto.
4243 (Event.Define): Ditto.
4245 (Operator.Define): Check that the underlying Method defined itself
4246 correctly - so it's MethodBuilder should not be null.
4248 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
4249 expression happens to be null.
4251 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
4252 members but as of now we don't seem to be able to do anything really useful with it.
4254 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
4255 not the EventBuilder.
4257 2001-12-18 Miguel de Icaza <miguel@ximian.com>
4259 * cs-tokenizer.cs: Add support for defines.
4260 Add support for #if, #elif, #else, #endif
4262 (eval_var): evaluates a variable.
4263 (eval): stubbed for evaluating functions.
4265 * cs-parser.jay: Pass the defines information
4267 * driver.cs: Add --define command line option.
4269 * decl.cs: Move MemberCore here.
4271 Make it the base class for DeclSpace. This allows us to catch and
4272 report 108 and 109 for everything now.
4274 * class.cs (TypeContainer.Define): Extract all the members
4275 before populating and emit the warning 108 (new keyword required
4276 to override) instead of having each member implement this.
4278 (MemberCore.Define): New abstract method, we will be using this in
4279 the warning reporting engine in Populate.
4281 (Operator.Define): Adjust to new MemberCore protocol.
4283 * const.cs (Const): This does not derive from Expression, it is a
4284 temporary object we use to create fields, it is a MemberCore.
4286 * class.cs (Method.Define): Allow the entry point to be in a
4289 * driver.cs: Rewrite the argument handler to clean it up a bit.
4291 * rootcontext.cs: Made it just an auxiliary namespace feature by
4292 making everything static.
4294 * driver.cs: Adapt code to use RootContext type name instead of
4297 * delegate.cs: Remove RootContext argument.
4299 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
4302 * class.cs (Event.Define): The lookup can fail.
4304 * cs-tokenizer.cs: Begin implementation of pre-procesor.
4306 * expression.cs: Resolve the this instance before invoking the code.
4308 2001-12-17 Miguel de Icaza <miguel@ximian.com>
4310 * cs-parser.jay: Add a production in element_access that allows
4311 the thing to become a "type" reference. This way we can parse
4312 things like "(string [])" as a type.
4314 Note that this still does not handle the more complex rules of
4318 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
4320 * ecore.cs: (CopyNewMethods): new utility function used to
4321 assemble the list of methods from running FindMembers.
4323 (MemberLookup): Rework FindMembers so that
4325 2001-12-16 Miguel de Icaza <miguel@ximian.com>
4327 * class.cs (TypeContainer): Remove Delegates who fail to be
4330 * delegate.cs (Populate): Verify that we dont get null return
4331 values. TODO: Check for AsAccessible.
4333 * cs-parser.jay: Use basename to emit error 574 (destructor should
4334 have the same name as container class), not the full name.
4336 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
4337 possible representation.
4339 Also implements integer type suffixes U and L.
4341 2001-12-15 Miguel de Icaza <miguel@ximian.com>
4343 * expression.cs (ArrayCreation.DoResolve): We need to do the
4344 argument resolution *always*.
4346 * decl.cs: Make this hold the namespace. Hold the root context as
4348 (LookupType): Move here.
4350 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
4352 * location.cs (Row, Name): Fixed the code, it was always returning
4353 references to the first file.
4355 * interface.cs: Register properties defined through interfaces.
4357 * driver.cs: Add support for globbing on the command line
4359 * class.cs (Field): Make it derive from MemberCore as well.
4362 2001-12-15 Ravi Pratap <ravi@ximian.com>
4364 * class.cs (Event::Define): Check that the type of the event is a delegate
4365 type else flag error #66.
4367 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
4370 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
4371 values of EntryPoint, CharSet etc etc.
4373 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
4375 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
4376 be null and we should ignore this. I am not sure if this is really clean. Apparently,
4377 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
4378 which needs this to do its work.
4380 * ../errors/cs0066.cs : Add.
4382 2001-12-14 Miguel de Icaza <miguel@ximian.com>
4384 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
4387 * class.cs: (MethodSignature.MethodSignature): Removed hack that
4388 clears out the parameters field.
4389 (MemberSignatureCompare): Cleanup
4391 (MemberCore): New base class used to share code between MethodCore
4394 (RegisterRequiredImplementations) BindingFlags.Public requires
4395 either BindingFlags.Instace or Static. Use instance here.
4397 (Property): Refactored code to cope better with the full spec.
4399 * parameter.cs (GetParameterInfo): Return an empty array instead
4402 * class.cs (Property): Abstract or extern properties have no bodies.
4404 * parameter.cs (GetParameterInfo): return a zero-sized array.
4406 * class.cs (TypeContainer.MethodModifiersValid): Move all the
4407 method modifier validation to the typecontainer so we can reuse
4410 (MethodCore.ParameterTypes): return an empty sized array of types.
4412 (Property.Define): Test property modifier validity.
4414 Add tests for sealed/override too.
4416 (Method.Emit): abstract or extern methods have no bodies.
4418 2001-12-14 Ravi Pratap <ravi@ximian.com>
4420 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
4423 (Method::Define, ::Emit): Modify accordingly.
4425 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
4427 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
4429 * makefile: Pass in /unsafe.
4431 2001-12-13 Miguel de Icaza <miguel@ximian.com>
4433 * class.cs (MakeKey): Kill routine.
4435 * class.cs (TypeContainer.Define): Correctly define explicit
4436 method implementations (they require the full interface name plus
4439 * typemanager.cs: Deply the PtrHashtable here and stop using the
4440 lame keys. Things work so much better.
4442 This of course broke everyone who depended on `RegisterMethod' to
4443 do the `test for existance' test. This has to be done elsewhere.
4445 * support.cs (PtrHashtable): A hashtable that avoid comparing with
4446 the object stupid Equals method (because, that like fails all over
4447 the place). We still do not use it.
4449 * class.cs (TypeContainer.SetRequiredInterface,
4450 TypeContainer.RequireMethods): Killed these two routines and moved
4451 all the functionality to RegisterRequiredImplementations.
4453 (TypeContainer.RegisterRequiredImplementations): This routine now
4454 registers all the implementations required in an array for the
4455 interfaces and abstract methods. We use an array of structures
4456 which can be computed ahead of time to reduce memory usage and we
4457 also assume that lookups are cheap as most classes will not
4458 implement too many interfaces.
4460 We also avoid creating too many MethodSignatures.
4462 (TypeContainer.IsInterfaceMethod): Update and optionally does not
4463 clear the "pending" bit if we find that there are problems with
4466 (TypeContainer.VerifyPendingMethods): Update to report errors of
4467 methods that look like implementations but are not.
4469 (TypeContainer.Define): Add support for explicit interface method
4472 2001-12-12 Miguel de Icaza <miguel@ximian.com>
4474 * typemanager.cs: Keep track of the parameters here instead of
4475 being a feature of the TypeContainer.
4477 * class.cs: Drop the registration of parameters here, as
4478 InterfaceMethods are also interface declarations.
4480 * delegate.cs: Register methods with the TypeManager not only with
4481 the TypeContainer. This code was buggy.
4483 * interface.cs: Full registation here.
4485 2001-12-11 Miguel de Icaza <miguel@ximian.com>
4487 * expression.cs: Remove reducer for binary expressions, it can not
4490 * const.cs: Put here the code that used to go into constant.cs

4590 2001-12-04 Miguel de Icaza <miguel@ximian.com>
4592 * statement.cs: The correct type for the EmptyExpression is the
4593 element_type, not the variable type. Ravi pointed this out.
4595 2001-12-04 Ravi Pratap <ravi@ximian.com>
4597 * class.cs (Method::Define): Handle PInvoke methods specially
4598 by using DefinePInvokeMethod instead of the usual one.

4690 * enum.cs (LookupEnumValue): Re-write various bits, return an object value
4691 instead of a Literal - much easier.

4857 (Cast.Cast): Take an expression as the target type.
4859 * cs-parser.jay (cast_expression): Remove old hack that only
4860 allowed a limited set of types to be handled. Now we take a
4861 unary_expression and we resolve to a type during semantic
4864 Use the grammar productions from Rhys to handle casts (this is
4865 not complete like Rhys syntax yet, we fail to handle that corner
4866 case that C# has regarding (-x), but we will get there.
4868 2001-11-22 Ravi Pratap <ravi@ximian.com>
4870 * class.cs (EmitFieldInitializer): Take care of the case when we have a
4871 field which is an array type.

4885 (MemberAccess::DoResolve): Fix the code which handles Enum literals to set
4886 the correct type etc.
4888 (ConvertExplicit): Handle Enum types by examining the underlying type.
4890 2001-11-21 Ravi Pratap <ravi@ximian.com>

4903 BindingFlags.Instance as well
4905 * ecore.cs (Expression.TryImplicitIntConversion): Wrap the result

4910 (Expression.ConvertExplicit): Add explicit type conversions done
4913 (Expression.ImplicitNumericConversion): Oops, forgot to test for

4917 2001-11-21 Miguel de Icaza <miguel@ximian.com>
4919 * cs-parser.jay (for_statement): Reworked the way For works: now
4920 we declare manually any variables that are introduced in
4921 for_initializer to solve the problem of having out-of-band code
4922 emition (that is what got for broken).
4924 (declaration_statement): Perform the actual variable declaration
4925 that used to be done in local_variable_declaration here.
4927 (local_variable_declaration): Do not declare anything, just pass

4995 we can use this elsewhere.
4997 * statement.cs: Finish implementation of foreach for single
5000 * cs-parser.jay: Use an out-of-band stack to pass information
5001 around, I wonder why I need this.

5005 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
5006 function used to return a static Parameters structure. Used for
5007 empty parameters, as those are created very frequently.

5011 2001-11-15 Ravi Pratap <ravi@ximian.com>
5013 * interface.cs : Default modifier is private, not public. The

5016 2001-11-15 Ravi Pratap <ravi@ximian.com>
5018 * support.cs (ReflectionParameters): Fix logic to determine
5019 whether the last parameter is a params one. Test 9 passes again.

5052 2001-11-09 Miguel de Icaza <miguel@ximian.com>

5073 way we can report the error correctly for missing return values.
5075 * class.cs (Method.Emit): Clean up.
5077 * expression.cs (Argument.Resolve): Take another argument: the
5078 location where this argument is used. Notice that this is not
5079 part of the "Argument" class as to reduce the size of the
5080 structure (we know the approximate location anyways).
5082 Test if the argument is a variable-reference, if not, then
5083 complain with a 206.
5085 (Argument.Emit): Emit addresses of variables.
5087 (Argument.FullDesc): Simplify.
5089 (Invocation.DoResolve): Update for Argument.Resolve.

5116 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
5117 enumerations that are used in heavily used structures derive from
5118 byte in a laughable and pathetic attempt to reduce memory usage.
5119 This is the kind of pre-optimzations that you should not do at
5120 home without adult supervision.
5122 * expression.cs (UnaryMutator): New class, used to handle ++ and
5123 -- separatedly from the other unary operators. Cleans up the
5124 code, and kills the ExpressionStatement dependency in Unary.
5126 (Unary): Removed `method' and `Arguments' from this class, making
5127 it smaller, and moving it all to SimpleCall, so I can reuse this
5128 code in other locations and avoid creating a lot of transient data
5129 strucutres when not required.
5131 * cs-parser.jay: Adjust for new changes.
5133 2001-11-11 Miguel de Icaza <miguel@ximian.com>

5907 name as it is a type declaration.
5909 * delegate.cs (ReturnType, Name): Rename members to these. Make them
5912 (DefineDelegate): Renamed from Define. Does the same thing essentially,
5913 as TypeContainer::DefineType.
5915 (Populate): Method in which all the definition of the various methods (Invoke)
5918 (Emit): Emit any code, if necessary. I am not sure about this really, but let's
5921 (CloseDelegate): Finally creates the delegate.
5923 * class.cs (TypeContainer::DefineType): Update to define delegates.
5924 (Populate, Emit and CloseType): Do the same thing here too.
5926 * rootcontext.cs (ResolveTree, PopulateTypes, EmitCode, CloseTypes): Include
5927 delegates in all these operations.
5929 2001-10-14 Miguel de Icaza <miguel@ximian.com>
5931 * expression.cs: LocalTemporary: a new expression used to
5932 reference a temporary that has been created.
5934 * assign.cs: Handle PropertyAccess back here, so that we can
5935 provide the proper semantic access to properties.
5937 * expression.cs (Expression::ConvertReferenceExplicit): Implement
5938 a few more explicit conversions.
5940 * modifiers.cs: `NEW' modifier maps to HideBySig.
5942 * expression.cs (PropertyExpr): Make this into an
5943 ExpressionStatement, and support the EmitStatement code path.
5945 Perform get/set error checking, clean up the interface.
5947 * assign.cs: recognize PropertyExprs as targets, and if so, turn
5948 them into toplevel access objects.
5950 2001-10-12 Miguel de Icaza <miguel@ximian.com>
5952 * expression.cs: PropertyExpr::PropertyExpr: use work around the
5955 * typemanager.cs: Keep track here of our PropertyBuilders again to
5956 work around lameness in SRE.
5958 2001-10-11 Miguel de Icaza <miguel@ximian.com>
5960 * expression.cs (LValue::LValueResolve): New method in the
5961 interface, used to perform a second resolution pass for LValues.
5963 (This::DoResolve): Catch the use of this in static methods.
5965 (This::LValueResolve): Implement.
5967 (This::Store): Remove warning, assigning to `this' in structures
5970 (Invocation::Emit): Deal with invocation of
5971 methods on value types. We need to pass the address to structure
5972 methods rather than the object itself. (The equivalent code to
5973 emit "this" for structures leaves the entire structure on the
5974 stack instead of a pointer to it).
5976 (ParameterReference::DoResolve): Compute the real index for the
5977 argument based on whether the method takes or not a `this' pointer
5978 (ie, the method is static).
5980 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store
5981 value types returned from functions when we need to invoke a
5982 method on the sturcture.
5985 2001-10-11 Ravi Pratap <ravi@ximian.com>
5987 * class.cs (TypeContainer::DefineType): Method to actually do the business of
5988 defining the type in the Modulebuilder or Typebuilder. This is to take
5989 care of nested types which need to be defined on the TypeBuilder using
5992 (TypeContainer::GetClassBases): Implement. Essentially the code from the
5993 methods in RootContext, only ported to be part of TypeContainer.
5995 (TypeContainer::GetInterfaceOrClass): Ditto.
5997 (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
5999 * interface.cs (Interface::DefineInterface): New method. Does exactly
6000 what RootContext.CreateInterface did earlier, only it takes care of nested types
6003 (Interface::GetInterfaces): Move from RootContext here and port.
6005 (Interface::GetInterfaceByName): Same here.
6007 * rootcontext.cs (ResolveTree): Re-write.

6011 * class.cs (TypeContainer::Populate): Populate nested types too.
6012 (TypeContainer::Emit): Emit nested members too.
6014 * typemanager.cs (AddUserType): Do not make use of the FullName property,
6015 instead just use the name argument passed in as it is already fully
6018 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
6019 to TypeContainer mapping to see if a type is user-defined.
6021 * class.cs (TypeContainer::CloseType): Implement.
6023 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
6024 the default constructor.
6026 (TypeContainer::Populate): Fix minor bug which led to creating default constructors
6029 (Constructor::IsDefault): Fix up logic to determine if it is the default constructor
6031 * interface.cs (CloseType): Create the type here.
6033 * rootcontext.cs (CloseTypes): Re-write to recursively close types by running through
6036 Remove all the methods which are now in TypeContainer.
6038 2001-10-10 Ravi Pratap <ravi@ximian.com>
6040 * delegate.cs (Define): Re-write bits to define the delegate
6043 2001-10-10 Miguel de Icaza <miguel@ximian.com>
6045 * makefile: Renamed the compiler to `mcs.exe' instead of compiler.exe
6047 * expression.cs (ImplicitReferenceConversion): handle null as well
6048 as a source to convert to any reference type.
6050 * statement.cs (Return): Perform any implicit conversions to
6051 expected return type.
6053 Validate use of return statement.
6055 * codegen.cs (EmitContext): Pass the expected return type here.
6057 * class.cs (Method, Constructor, Property): Pass expected return
6058 type to EmitContext.
6060 2001-10-09 Miguel de Icaza <miguel@ximian.com>
6062 * expression.cs: Make DoResolve take an EmitContext instead of a
6065 Replaced `l' and `location' for `loc', for consistency.
6067 (Error, Warning): Remove unneeded Tc argument.
6069 * assign.cs, literal.cs, constant.cs: Update to new calling
6072 * codegen.cs: EmitContext now contains a flag indicating whether
6073 code is being generated in a static method or not.
6075 * cs-parser.jay: DecomposeQI, new function that replaces the old
6076 QualifiedIdentifier. Now we always decompose the assembled
6077 strings from qualified_identifier productions into a group of
6080 2001-10-08 Miguel de Icaza <miguel@ximian.com>
6082 * rootcontext.cs: Deal with field-less struct types correctly now
6083 by passing the size option to Define Type.
6085 * class.cs: Removed hack that created one static field.
6087 2001-10-07 Miguel de Icaza <miguel@ximian.com>
6089 * statement.cs: Moved most of the code generation here.
6091 2001-10-09 Ravi Pratap <ravi@ximian.com>
6093 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
6096 (ElementAccess): Remove useless bits for now - keep checks as the spec
6099 2001-10-08 Ravi Pratap <ravi@ximian.com>
6101 * expression.cs (ElementAccess::DoResolve): Remove my crap code
6102 and start performing checks according to the spec.
6104 2001-10-07 Ravi Pratap <ravi@ximian.com>
6106 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
6107 rank_specifiers instead.
6109 (rank_specifiers): Change the order in which the rank specifiers are stored
6111 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
6113 * expression.cs (ElementAccess): Implement the LValue interface too.
6115 2001-10-06 Ravi Pratap <ravi@ximian.com>
6117 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
6118 except that user defined conversions are not included.
6120 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
6121 perform the conversion of the return type, if necessary.
6123 (New::DoResolve): Check whether we are creating an array or an object
6124 and accordingly do the needful.
6126 (New::Emit): Same here.
6128 (New::DoResolve): Implement guts of array creation.
6130 (New::FormLookupType): Helper function.
6132 2001-10-07 Miguel de Icaza <miguel@ximian.com>
6134 * codegen.cs: Removed most of the code generation here, and move the
6135 corresponding code generation bits to the statement classes.
6137 Added support for try/catch/finalize and throw.
6139 * cs-parser.jay: Added support for try/catch/finalize.
6141 * class.cs: Catch static methods having the flags override,
6142 virtual or abstract.
6144 * expression.cs (UserCast): This user cast was not really doing
6145 what it was supposed to do. Which is to be born in fully resolved
6146 state. Parts of the resolution were being performed at Emit time!
6150 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6152 * expression.cs: Implicity convert the result from UserCast.
6154 2001-10-05 Ravi Pratap <ravi@ximian.com>
6156 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
6157 prevented it from working correctly.
6159 (ConvertExplicit): Make the first try, a call to ConvertImplicitStandard, not
6160 merely ConvertImplicit.
6162 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6164 * typemanager.cs: Make the LookupTypeContainer function static,
6165 and not per-instance.
6167 * class.cs: Make static FindMembers (the one that takes a Type
6170 * codegen.cs: Add EmitForeach here.
6172 * cs-parser.jay: Make foreach a toplevel object instead of the
6173 inline expansion, as we need to perform semantic analysis on it.
6175 2001-10-05 Ravi Pratap <ravi@ximian.com>
6177 * expression.cs (Expression::ImplicitUserConversion): Rename to
6178 UserDefinedConversion.
6180 (Expression::UserDefinedConversion): Take an extra argument specifying
6181 whether we look for explicit user conversions too.
6183 (Expression::ImplicitUserConversion): Make it a call to UserDefinedConversion.

6192 * expression.cs (Cast): Record location info.
6194 (Expression::ConvertExplicit): Take location argument.
6196 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
6197 to determine if we are doing explicit conversions.
6199 (UserCast::Emit): Update accordingly.
6201 (Expression::ConvertExplicit): Report an error if everything fails.
6203 * ../errors/cs0030.cs : Add.
6205 2001-10-04 Miguel de Icaza <miguel@ximian.com>
6207 * modifiers.cs: If the ABSTRACT keyword is present, also set the
6208 virtual and newslot bits.
6210 * class.cs (TypeContainer::RegisterRequiredImplementations):
6211 Record methods we need.
6213 (TypeContainer::MakeKey): Helper function to make keys for
6214 MethodBases, since the Methodbase key is useless.
6216 (TypeContainer::Populate): Call RegisterRequiredImplementations
6217 before defining the methods.
6219 Create a mapping for method_builders_to_methods ahead of time
6220 instead of inside a tight loop.
6222 (::RequireMethods): Accept an object as the data to set into the
6223 hashtable so we can report interface vs abstract method mismatch.
6225 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6227 * report.cs: Make all of it static.
6229 * rootcontext.cs: Drop object_type and value_type computations, as
6230 we have those in the TypeManager anyways.
6232 Drop report instance variable too, now it is a global.
6234 * driver.cs: Use try/catch on command line handling.
6236 Add --probe option to debug the error reporting system with a test
6239 * report.cs: Add support for exiting program when a probe
6240 condition is reached.
6242 2001-10-03 Ravi Pratap <ravi@ximian.com>
6244 * expression.cs (Binary::DoNumericPromotions): Fix the case when
6245 we do a forcible conversion regardless of type, to check if
6246 ForceConversion returns a null.
6248 (Binary::error19): Use location to report error.
6250 (Unary::error23): Use location here too.
6252 * ../errors/cs0019.cs : Check in.
6254 * ../errors/cs0023.cs : Check in.
6256 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
6257 case of a non-null MethodInfo object with a length of 0 !
6259 (Binary::ResolveOperator): Flag error if overload resolution fails to find
6260 an applicable member - according to the spec :-)
6261 Also fix logic to find members in base types.
6263 (Unary::ResolveOperator): Same here.
6265 (Unary::report23): Change name to error23 and make first argument a TypeContainer
6266 as I was getting thoroughly confused between this and error19 :-)
6268 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
6269 (::FindMostEncompassedType): Implement.
6270 (::FindMostEncompassingType): Implement.
6271 (::StandardConversionExists): Implement.
6273 (UserImplicitCast): Re-vamp. We now need info about most specific
6274 source and target types so that we can do the necessary conversions.
6276 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
6277 mathematical union with no duplicates.
6279 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6281 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
6282 in order from base classes to child classes, so that we can in
6283 child classes look up in our parent for method names and
6284 attributes (required for handling abstract, virtual, new, override
6285 constructs: we need to instrospect our base class, and if we dont
6286 populate the classes in order, the introspection might be
6287 incorrect. For example, a method could query its parent before
6288 the parent has any methods and would determine that the parent has
6289 no abstract methods (while it could have had them)).
6291 (RootContext::CreateType): Record the order in which we define the
6294 2001-10-02 Miguel de Icaza <miguel@ximian.com>
6296 * class.cs (TypeContainer::Populate): Also method definitions can
6297 fail now, keep track of this.
6299 (TypeContainer::FindMembers): Implement support for
6300 DeclaredOnly/noDeclaredOnly flag.
6302 (Constructor::Emit) Return the ConstructorBuilder.
6304 (Method::Emit) Return the MethodBuilder.
6305 Check for abstract or virtual methods to be public.
6307 * rootcontext.cs (RootContext::CreateType): Register all the
6308 abstract methods required for the class to be complete and the
6309 interface methods that must be implemented.
6311 * cs-parser.jay: Report error 501 (method requires body if it is
6312 not marked abstract or extern).
6314 * expression.cs (TypeOf::Emit): Implement.
6316 * typemanager.cs: runtime_handle_type, new global type.
6318 * class.cs (Property::Emit): Generate code for properties.
6320 2001-10-02 Ravi Pratap <ravi@ximian.com>
6322 * expression.cs (Unary::ResolveOperator): Find operators on base type
6323 too - we now conform exactly to the spec.
6325 (Binary::ResolveOperator): Same here.
6327 * class.cs (Operator::Define): Fix minor quirk in the tests.
6329 * ../errors/cs0215.cs : Added.
6331 * ../errors/cs0556.cs : Added.
6333 * ../errors/cs0555.cs : Added.
6335 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6337 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
6338 single integer which is really efficient
6340 2001-10-01 Ravi Pratap <ravi@ximian.com>
6342 * expression.cs (Expression::ImplicitUserConversion): Use location
6343 even in the case when we are examining True operators.
6345 * class.cs (Operator::Define): Perform extensive checks to conform
6346 with the rules for operator overloading in the spec.
6348 * expression.cs (Expression::ImplicitReferenceConversion): Implement
6349 some of the other conversions mentioned in the spec.
6351 * typemanager.cs (array_type): New static member for the System.Array built-in
6354 (cloneable_interface): For System.ICloneable interface.
6356 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
6357 we start resolving the tree and populating types.
6359 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
6361 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6363 * expression.cs (Expression::ExprClassFromMemberInfo,
6364 Expression::Literalize): Create literal expressions from
6365 FieldInfos which are literals.
6367 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
6368 type casts, because they were wrong. The test suite in tests
6371 (ImplicitNumericConversion): ushort to ulong requires a widening
6374 Int32 constant to long requires widening cast as well.
6376 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
6377 for integers because the type on the stack is not i4.
6379 2001-09-30 Miguel de Icaza <miguel@ximian.com>
6381 * expression.cs (report118): require location argument.
6383 * parameter.cs: Do not dereference potential null value.
6385 * class.cs: Catch methods that lack the `new' keyword when
6386 overriding a name. Report warnings when `new' is used without
6387 anything being there to override.
6389 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
6391 * class.cs: Only add constructor to hashtable if it is non-null
6392 (as now constructors can fail on define).
6394 (TypeManager, Class, Struct): Take location arguments.
6396 Catch field instance initialization in structs as errors.
6398 accepting_filter: a new filter for FindMembers that is static so
6399 that we dont create an instance per invocation.
6401 (Constructor::Define): Catch errors where a struct constructor is
6404 * cs-parser.jay: Pass location information for various new
6407 * delegate.cs (Delegate): take a location argument.
6409 * driver.cs: Do not call EmitCode if there were problesm in the
6410 Definition of the types, as many Builders wont be there.
6412 * decl.cs (Decl::Decl): Require a location argument.
6414 * cs-tokenizer.cs: Handle properly hex constants that can not fit
6415 into integers, and find the most appropiate integer for it.
6417 * literal.cs: Implement ULongLiteral.
6419 * rootcontext.cs: Provide better information about the location of
6420 failure when CreateType fails.
6422 2001-09-29 Miguel de Icaza <miguel@ximian.com>
6424 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
6427 * expression.cs (Binary::CheckShiftArguments): Add missing type
6429 (Binary::ResolveOperator): Add type to the logical and and logical
6430 or, Bitwise And/Or and Exclusive Or code paths, it was missing
6433 (Binary::DoNumericPromotions): In the case where either argument
6434 is ulong (and most signed types combined with ulong cause an
6435 error) perform implicit integer constant conversions as well.
6437 2001-09-28 Miguel de Icaza <miguel@ximian.com>
6439 * expression.cs (UserImplicitCast): Method should always be
6441 (Invocation::BetterConversion): Simplified test for IntLiteral.
6443 (Expression::ImplicitNumericConversion): Split this routine out.
6444 Put the code that performs implicit constant integer conversions
6447 (Expression::Resolve): Become a wrapper around DoResolve so we can
6448 check eclass and type being set after resolve.
6450 (Invocation::Badness): Remove this dead function
6452 (Binary::ResolveOperator): Do not compute the expensive argumnets
6453 unless we have a union for it.
6455 (Probe::Emit): Is needs to do an isinst and then
6456 compare against null.
6458 (::CanConvert): Added Location argument. If the Location argument
6459 is null (Location.Null), then we do not report errors. This is
6460 used by the `probe' mechanism of the Explicit conversion. We do
6461 not want to generate an error for something that the user
6462 explicitly requested to be casted. But the pipeline for an
6463 explicit cast first tests for potential implicit casts.
6465 So for now, if the Location is null, it means `Probe only' to
6466 avoid adding another argument. Might have to revise this
6469 (ClassCast): New class used to type cast objects into arbitrary
6470 classes (used in Explicit Reference Conversions).
6472 Implement `as' as well.
6474 Reverted all the patches from Ravi below: they were broken:
6476 * The use of `level' as a mechanism to stop recursive
6477 invocations is wrong. That was there just to catch the
6478 bug with a strack trace but not as a way of addressing
6481 To fix the problem we have to *understand* what is going
6482 on and the interactions and come up with a plan, not
6483 just get things going.
6485 * The use of the type conversion cache that I proposed
6486 last night had an open topic: How does this work across
6487 protection domains. A user defined conversion might not
6488 be public in the location where we are applying the
6489 conversion, a different conversion might be selected
6490 (ie, private A->B (better) but public B->A (worse),
6491 inside A, A->B applies, but outside it, B->A will
6494 * On top of that (ie, even if the above is solved),
6495 conversions in a cache need to be abstract. Ie, `To
6496 convert from an Int to a Short use an OpcodeCast', not
6497 `To convert from an Int to a Short use the OpcodeCast on
6498 the variable 5' (which is what this patch was doing).
6500 2001-09-28 Ravi Pratap <ravi@ximian.com>
6502 * expression.cs (Invocation::ConversionExists): Re-write to use
6503 the conversion cache
6505 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
6506 cache all conversions done, not just user-defined ones.
6508 (Invocation::BetterConversion): The real culprit. Use ConversionExists
6509 to determine if a conversion exists instead of acutually trying to
6510 perform the conversion. It's faster too.
6512 (Expression::ConvertExplicit): Modify to use ConversionExists to check
6513 and only then attempt the implicit conversion.
6515 2001-09-28 Ravi Pratap <ravi@ximian.com>
6517 * expression.cs (ConvertImplicit): Use a cache for conversions
6518 already found. Check level of recursion and bail out if necessary.
6520 2001-09-28 Miguel de Icaza <miguel@ximian.com>
6522 * typemanager.cs (string_concat_string_string, string_concat_object_object):
6523 Export standard methods that we expect for string operations.
6525 * statement.cs (Block::UsageWarning): Track usage of variables and
6526 report the errors for not used variables.
6528 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
6531 2001-09-27 Miguel de Icaza <miguel@ximian.com>
6533 * codegen.cs: remove unnneded code
6535 * expression.cs: Removed BuiltinTypeAccess class
6537 Fix the order in which implicit conversions are
6540 The previous fixed dropped support for boxed conversions (adding a
6541 test to the test suite now)
6543 (UserImplicitCast::CanConvert): Remove test for source being null,
6544 that code is broken. We should not feed a null to begin with, if
6545 we do, then we should track the bug where the problem originates
6546 and not try to cover it up here.
6548 Return a resolved expression of type UserImplicitCast on success
6549 rather than true/false. Ravi: this is what I was talking about,
6550 the pattern is to use a static method as a "constructor" for
6553 Also, do not create arguments until the very last minute,
6554 otherwise we always create the arguments even for lookups that
6555 will never be performed.
6557 (UserImplicitCast::Resolve): Eliminate, objects of type
6558 UserImplicitCast are born in a fully resolved state.
6560 * typemanager.cs (InitCoreTypes): Init also value_type
6563 * expression.cs (Cast::Resolve): First resolve the child expression.
6565 (LValue): Add new method AddressOf to be used by
6568 Change the argument of Store to take an EmitContext instead of an
6569 ILGenerator, because things like FieldExpr need to be able to call
6570 their children expression to generate the instance code.
6572 (Expression::Error, Expression::Warning): Sugar functions for
6575 (Expression::MemberLookup): Accept a TypeContainer instead of a
6576 Report as the first argument.
6578 (Expression::ResolvePrimary): Killed. I still want to improve
6579 this as currently the code is just not right.
6581 (Expression::ResolveMemberAccess): Simplify, but it is still
6584 (Unary::Resolve): Catch errors in AddressOf operators.
6586 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
6587 index to a byte for the short-version, or the compiler will choose
6588 the wrong Emit call, which generates the wrong data.
6590 (ParameterReference::Emit, ::Store): same.
6592 (FieldExpr::AddressOf): Implement.
6594 * typemanager.cs: TypeManager: made public variable instead of
6597 * driver.cs: document --fatal.

6608 with q being null, since this was introducing a bug.
6610 * expression.cs (ConvertImplicit): Do built-in conversions first.
6612 2001-09-27 Ravi Pratap <ravi@ximian.com>
6614 * expression.cs (UserImplicitCast::Resolve): Fix bug.
6616 2001-09-27 Ravi Pratap <ravi@ximian.com>
6618 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
6619 I had introduced long ago (what's new ?).
6621 * expression.cs (UserImplicitCast::CanConvert): Static method to do
6622 the work of all the checking.
6623 (ConvertImplicit): Call CanConvert and only then create object if necessary.
6624 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
6626 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
6627 that is the right way.

6630 overloading resolution. Use everywhere instead of cutting and pasting code.
6632 (Binary::ResolveOperator): Use MakeUnionSet.
6634 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
6635 we have to convert to bool types. Not complete yet.
6637 2001-09-27 Miguel de Icaza <miguel@ximian.com>
6639 * typemanager.cs (TypeManager::CSharpName): support ushort.
6641 * expression.cs (Expression::TryImplicitIntConversion): Attempts
6642 to provide an expression that performsn an implicit constant int
6643 conversion (section 6.1.6).
6644 (Expression::ConvertImplicitRequired): Reworked to include
6645 implicit constant expression conversions.
6647 (Expression::ConvertNumericExplicit): Finished.
6649 (Invocation::Emit): If InstanceExpression is null, then it means
6650 that we perform a call on this.
6652 2001-09-26 Miguel de Icaza <miguel@ximian.com>
6654 * expression.cs (Unary::Emit): Remove some dead code.
6655 (Probe): Implement Resolve and Emit for `is'.
6656 (Expression::ConvertImplicitRequired): Attempt to do constant
6657 expression conversions here. Maybe should be moved to
6658 ConvertImplicit, but I am not sure.
6659 (Expression::ImplicitLongConstantConversionPossible,
6660 Expression::ImplicitIntConstantConversionPossible): New functions
6661 that tell whether is it possible to apply an implicit constant
6662 expression conversion.

6675 ones that the spec expects (as we are just stringizing the
6678 * expression.cs (Unary::ResolveOperator): Fix bug: Use
6679 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
6680 previous usage did only work for our methods.
6681 (Expression::ConvertImplicit): Handle decimal implicit numeric
6682 conversions as well.
6683 (Expression::InternalTypeConstructor): Used to invoke constructors
6684 on internal types for default promotions.
6686 (Unary::Emit): Implement special handling for the pre/post
6687 increment/decrement for overloaded operators, as they need to have
6688 the same semantics as the other operators.
6690 (Binary::ResolveOperator): ditto.

6692 (UserImplicitCast::Resolve): ditto.
6694 2001-09-26 Ravi Pratap <ravi@ximian.com>
6696 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded

6711 expressions that can appear in statements, so that we can provide
6712 an alternate path to generate expression that do not leave a value
6715 (Expression::Emit, and all the derivatives): We no longer return
6716 whether a value is left on the stack or not. Every expression
6717 after being emitted leaves a single value on the stack.

6743 (ConvertImplicit): Do user-defined conversion if it exists.
6745 2001-09-24 Miguel de Icaza <miguel@ximian.com>
6747 * assign.cs: track location.
6748 (Resolve): Use implicit conversions on assignment.
6750 * literal.cs: Oops. Not good, Emit of short access values should

6791 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
6792 Also take an additional TypeContainer argument.
6794 * All over : Pass in TypeContainer as argument to OverloadResolve.
6796 * typemanager.cs (CSharpName): Update to check for the string type and return

6813 * typemanager.cs: declare and load enum_type, delegate_type and
6816 * expression.cs (Expression::Emit): Now emit returns a value that
6817 tells whether a value is left on the stack or not. This strategy
6818 might be reveted tomorrow with a mechanism that would address
6819 multiple assignments.
6820 (Expression::report118): Utility routine to report mismatches on
6823 (Unary::Report23): Report impossible type/operator combination
6826 (Unary::IsIncrementableNumber): Whether the type can be

6871 * expression.cs: Instead of having FIXMEs in the Resolve
6872 functions, throw exceptions so it is obvious that we are facing a
6875 * cs-parser.jay (invocation_expression): Pass Location information.
6877 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
6878 Use a basename for those routines because .NET does not like paths

6890 * expression.cs (Unary::ResolveOperator): return the child
6891 expression for expressions which are just +expr.
6892 (Unary::ResolveOperator): Return negative literals for -LITERAL
6893 expressions (otherwise they are Unary {Literal}).
6894 (Invocation::Badness): Take into account `Implicit constant
6895 expression conversions'.
6897 * literal.cs (LongLiteral): Implement long literal class.
6898 (IntLiteral): export the `Value' of the intliteral.
6900 2001-09-19 Ravi Pratap <ravi@ximian.com>

6915 * expression.cs (Unary::Resolve): Implement.
6916 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
6917 operators are found instead of making noise ;-)
6918 (Unary::ResolveOperator): New method to do precisely the same thing which
6919 Binary::ResolveOperator does for Binary expressions.
6920 (Unary.method, .Arguments): Add.
6921 (Unary::OperName): Implement.
6922 (Unary::ForceConversion): Copy and Paste !
6924 * class.cs (Operator::Define): Fix a small bug for the case when we have
6927 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
6928 for the inbuilt operators. Only overloading works for now ;-)
6930 2001-09-18 Miguel de Icaza <miguel@ximian.com>
6932 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
6933 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

6946 (FieldExpr::Emit): Implement.
6948 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
6949 the last instruction contains a return opcode to avoid generating
6950 the last `ret' instruction (this generates correct code, and it is
6951 nice to pass the peverify output).
6953 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
6954 initializer for static and instance variables.
6955 (Constructor::Emit): Allow initializer to be null in the case of
6956 static constructors. Only emit initializer for instance
6959 (TypeContainer::FindMembers): Return a null array if there are no

6969 * driver.cs: Stop compilation if there are parse errors.
6971 * cs-parser.jay (constructor_declaration): Provide default base

6974 initializers if none was specified.
6975 Catch the fact that constructors should not have parameters.
6977 * class.cs: Do not emit parent class initializers for static
6978 constructors, that should be flagged as an error.
6980 2001-09-18 Ravi Pratap <ravi@ximian.com>
6982 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
6983 Move back code into TypeContainer::Populate.

7012 (Expression::MemberLookup): Provide a version that allows to
7013 specify the MemberTypes and BindingFlags.
7015 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
7016 so it was not fetching variable information from outer blocks.
7018 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
7019 Beforefieldinit as it was buggy.
7021 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
7024 * class.cs (Constructor::Emit): Only emit if block is not null.
7025 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
7026 deal with this by semantically definining it as if the user had
7029 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
7030 constructors as we now "emit" them at a higher level.

7033 default constructors if none was provided.
7035 (ConstructorInitializer): Add methods Resolve and Emit.
7037 * expression.cs: Cast to ConstructorInfo instead of MethodInfo

7056 * class.cs (Operator::OpType): Change names to match the ones in Binary::Operator
7057 and Unary::Operator.
7059 * cs-parser.jay (operator_declaration, CheckBinaryOperator, CheckUnaryOperator): Update
7062 * expression.cs (Binary::method): New member to hold the MethodBase for the case when
7063 we have overloaded operators.
7064 (Binary::ResolveOperator): Implement the part which does the operator overload
7067 * class.cs (Operator::Emit): Implement.
7068 (TypeContainer::Emit): Emit the operators we have too.
7070 * expression.cs (Binary::Emit): Update to emit the appropriate code for
7071 the case when we have a user-defined operator.
7073 2001-09-17 Miguel de Icaza <miguel@ximian.com>

7077 2001-09-16 Ravi Pratap <ravi@ximian.com>

7105 2001-09-14 Miguel de Icaza <miguel@ximian.com>
7107 * class.cs (TypeContainer::FindMembers): Add support for

7110 of a Constructor and a Method.

7114 Load System assembly as well as part of the standard library.
7116 * report.cs: Allow throwing exceptions on errors for debugging.
7118 * modifiers.cs: Do not use `parent', instead use the real type
7119 container to evaluate permission settings.
7121 * class.cs: Put Ravi's patch back in. He is right, and we will
7122 have to cope with the
7124 2001-09-14 Ravi Pratap <ravi@ximian.com>
7126 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

7131 * driver.cs: Added --parse option that only parses its input files
7134 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
7135 incorrect. IsTopLevel is not used to tell whether an object is
7136 root_types or not (that can be achieved by testing this ==
7137 root_types). But to see if this is a top-level *class* (not
7138 necessarly our "toplevel" container).
7140 2001-09-14 Ravi Pratap <ravi@ximian.com>
7142 * enum.cs (Enum::Define): Modify to call the Lookup method on the
7143 parent instead of a direct call to GetType.
7145 2001-09-14 Ravi Pratap <ravi@ximian.com>
7147 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
7148 Modifiers.TypeAttr. This should just be a call to that method.
7150 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
7151 object so that we can determine if we are top-level or not.
7153 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
7156 * enum.cs (Enum::Define): Ditto.
7158 * modifiers.cs (FieldAttr): Re-write.
7160 * class.cs (TypeContainer::IsTopLevel): Change accessibility to public.
7161 (TypeContainer::HaveStaticConstructor): New property to provide access
7162 to precisely that info.
7164 * modifiers.cs (MethodAttr): Re-write.
7165 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
7167 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
7168 of top-level types as claimed.
7170 2001-09-13 Miguel de Icaza <miguel@ximian.com>
7172 * expression.cs (MemberLookup): Fruitless attempt to lookup
7173 constructors. Maybe I need to emit default constructors? That
7174 might be it (currently .NET emits this for me automatically).
7175 (Invocation::OverloadResolve): Cope with Arguments == null.
7176 (Invocation::EmitArguments): new function, shared by the new
7178 (Invocation::Emit): Handle static and instance methods. Emit
7179 proper call instruction for virtual or non-virtual invocations.
7180 (New::Emit): Implement.
7181 (New::Resolve): Implement.
7182 (MemberAccess:Resolve): Implement.

7185 (FieldExpr::Resolve): Set type.
7187 * support.cs: Handle empty arguments.

7190 SimpleLookup): Auxiliary routines to help parse a qualifier
7193 Update qualifier_identifier rule.
7195 * codegen.cs: Removed debugging messages.
7197 * class.cs: Make this a global thing, this acts just as a "key" to
7198 objects that we might have around.
7200 (Populate): Only initialize method_builders_to_methods once.
7202 * expression.cs (PropertyExpr): Initialize type from the
7205 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
7206 Resolve pattern. Attempt to implicitly convert value to boolean.
7209 * expression.cs: Set the type for the int32/int32 argument case.
7210 (Binary::ResolveOperator): Set the return type to boolean for
7211 comparission operators
7213 * typemanager.cs: Remove debugging print code.
7215 (Invocation::Resolve): resolve type.
7217 * class.cs: Allocate a MemberInfo of the correct size, as the code
7218 elsewhere depends on the test to reflect the correct contents.
7220 (Method::) Keep track of parameters, due to System.Reflection holes
7222 (TypeContainer::Populate): Keep track of MethodBuilders to Method
7225 (TypeContainer::FindMembers): Use ArrayList and then copy an array
7226 of the exact size and return that.
7228 (Class::LookupMethodByBuilder): New function that maps
7229 MethodBuilders to its methods. Required to locate the information
7230 on methods because System.Reflection bit us again.
7232 * support.cs: New file, contains an interface ParameterData and
7233 two implementations: ReflectionParameters and InternalParameters
7234 used to access Parameter information. We will need to grow this
7237 * expression.cs (Invocation::GetParameterData): implement a cache
7238 and a wrapper around the ParameterData creation for methods.
7239 (Invocation::OverloadResolve): Use new code.
7241 2001-09-13 Ravi Pratap <ravi@ximian.com>
7243 * class.cs (TypeContainer::EmitField): Remove and move into
7244 (Field::Define): here and modify accordingly.

7726 and re-write the code in the actions to extract the specific and
7727 general catch clauses by being a little smart ;-)
7729 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
7730 Hooray, try and catch statements parse fine !

7788 instead of ignoring the rank_specifiers.
7789 (expression_list): Implement to collect the expressions

7794 (opt_array_initializer): Modify accordingly.

7831 beginning, will continue tomorrow with more touches of polish. We

7839 emission to keep a context. Most of the code generation will be

7855 (Block::Block constructors): Link children.
7856 (Block::Child): Child Linker.
7857 (Block::EmitVariables): Emits IL variable declarations.
7859 * class.cs: Drop support for MethodGroups here, delay until
7861 (Method::): Applied the same simplification that I did before, and
7862 move from Properties to public readonly fields.
7863 (Method::ParameterTypes): Returns the parameter types for the
7864 function, and implements a cache that will be useful later when I
7865 do error checking and the semantic analysis on the methods is
7867 (Constructor::GetCallingConvention): Renamed from CallingConvetion
7868 and made a method, optional argument tells whether this is a class
7869 or a structure to apply the `has-this' bit.
7870 (Method::GetCallingConvention): Implement, returns the calling
7872 (Method::Define): Defines the type, a second pass is performed
7873 later to populate the methods.
7875 (Constructor::ParameterTypes): implement a cache similar to the
7876 one on Method::ParameterTypes, useful later when we do semantic
7879 (TypeContainer::EmitMethod): New method. Emits methods.
7881 * expression.cs: Removed MethodGroup class from here.
7883 * parameter.cs (Parameters::GetCallingConvention): new method.

7890 (Constructor::CallingConvention): Returns the calling convention.
7891 (Constructor::ParameterTypes): Returns the constructor parameter
7894 (TypeContainer::AddConstructor): Keep track of default constructor
7895 and the default static constructor.
7897 (Constructor::) Another class that starts using `public readonly'
7898 instead of properties.
7900 (Constructor::IsDefault): Whether this is a default constructor.
7902 (Field::) use readonly public fields instead of properties also.
7904 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
7905 track of static constructors; If none is used, turn on
7906 BeforeFieldInit in the TypeAttributes.
7908 * cs-parser.jay (opt_argument_list): now the return can be null
7909 for the cases where there are no arguments.
7911 (constructor_declarator): If there is no implicit `base' or
7912 `this', then invoke the default parent constructor.
7914 * modifiers.cs (MethodAttr): New static function maps a set of
7915 modifiers flags into a MethodAttributes enum
7916 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
7917 MethodAttr, TypeAttr to represent the various mappings where the
7919 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
7921 2001-08-19 Miguel de Icaza <miguel@ximian.com>

7927 for interface indexers.
7929 2001-08-17 Miguel de Icaza <miguel@ximian.com>
7931 * interface.cs (InterfaceMemberBase): Now we track the new status
7934 (PopulateProperty): Implement property population. Woohoo! Got
7935 Methods and Properties going today.
7937 Removed all the properties for interfaces, and replaced them with
7938 `public readonly' fields.
7940 2001-08-16 Miguel de Icaza <miguel@ximian.com>
7942 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
7943 initialize their hashtables/arraylists only when they are needed
7944 instead of doing this always.
7946 * parameter.cs: Handle refs and out parameters.
7948 * cs-parser.jay: Use an ArrayList to construct the arguments
7949 instead of the ParameterCollection, and then cast that to a
7952 * parameter.cs: Drop the use of ParameterCollection and use
7953 instead arrays of Parameters.
7955 (GetParameterInfo): Use the Type, not the Name when resolving
7958 2001-08-13 Miguel de Icaza <miguel@ximian.com>
7960 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
7961 and instead use public readonly fields.
7963 * class.cs: Put back walking code for type containers.
7965 2001-08-11 Miguel de Icaza <miguel@ximian.com>
7967 * class.cs (MakeConstant): Code to define constants.
7969 * rootcontext.cs (LookupType): New function. Used to locate types
7972 2001-08-08 Miguel de Icaza <miguel@ximian.com>
7974 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
7975 this System.Reflection code is. Kudos to Microsoft
7977 * typemanager.cs: Implement a type cache and avoid loading all
7978 types at boot time. Wrap in LookupType the internals. This made
7979 the compiler so much faster. Wow. I rule!
7981 * driver.cs: Make sure we always load mscorlib first (for
7982 debugging purposes, nothing really important).
7984 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
7985 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
7987 * rootcontext.cs: Lookup types on their namespace; Lookup types
7988 on namespaces that have been imported using the `using' keyword.
7990 * class.cs (TypeContainer::TypeAttr): Virtualize.
7991 (Class::TypeAttr): Return attributes suitable for this bad boy.
7992 (Struct::TypeAttr): ditto.
7993 Handle nested classes.
7994 (TypeContainer::) Remove all the type visiting code, it is now
7995 replaced with the rootcontext.cs code
7997 * rootcontext.cs (GetClassBases): Added support for structs.
7999 2001-08-06 Miguel de Icaza <miguel@ximian.com>
8001 * interface.cs, statement.cs, class.cs, parameter.cs,
8002 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
8003 Drop use of TypeRefs, and use strings instead.
8005 2001-08-04 Miguel de Icaza <miguel@ximian.com>
8009 * class.cs (Struct::Struct): set the SEALED flags after
8010 checking the modifiers.
8011 (TypeContainer::TypeAttr): new property, returns the
8012 TypeAttributes for a class.
8014 * cs-parser.jay (type_list): Oops, list production was creating a
8015 new list of base types.
8017 * rootcontext.cs (StdLib): New property.
8018 (GetInterfaceTypeByName): returns an interface by type name, and
8019 encapsulates error handling here.
8020 (GetInterfaces): simplified.
8021 (ResolveTree): Encapsulated all the tree resolution here.
8022 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
8025 * driver.cs: Add support for --nostdlib, to avoid loading the
8027 (Main): Do not put tree resolution here.
8029 * rootcontext.cs: Beginning of the class resolution.
8031 2001-08-03 Miguel de Icaza <miguel@ximian.com>
8033 * rootcontext.cs: Provide better error reporting.
8035 * cs-parser.jay (interface_base): set our $$ to be interfaces.
8037 * rootcontext.cs (CreateInterface): Handle the case where there
8038 are no parent interfaces.
8040 (CloseTypes): Routine to flush types at the end.
8041 (CreateInterface): Track types.
8042 (GetInterfaces): Returns an array of Types from the list of
8045 * typemanager.c (AddUserType): Mechanism to track user types (puts
8046 the type on the global type hash, and allows us to close it at the
8049 2001-08-02 Miguel de Icaza <miguel@ximian.com>
8051 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
8052 RecordInterface instead.
8054 * cs-parser.jay: Updated to reflect changes above.
8056 * decl.cs (Definition): Keep track of the TypeBuilder type that
8057 represents this type here. Not sure we will use it in the long
8058 run, but wont hurt for now.
8060 * driver.cs: Smaller changes to accomodate the new code.
8062 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
8065 * rootcontext.cs (CreateInterface): New method, used to create
8066 the System.TypeBuilder type for interfaces.
8067 (ResolveInterfaces): new entry point to resolve the interface
8069 (CodeGen): Property, used to keep track of the code generator.
8071 2001-07-26 Miguel de Icaza <miguel@ximian.com>
8073 * cs-parser.jay: Add a second production for delegate_declaration
8076 (enum_body): Put an opt_comma here instead of putting it on
8077 enum_body or enum_member_declarations so we can handle trailing
8078 commas on enumeration members. Gets rid of a shift/reduce.
8080 (type_list): Need a COMMA in the middle.
8082 (indexer_declaration): Tell tokenizer to recognize get/set
8084 * Remove old targets.
8086 * Re-add the parser target.
8088 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8090 * cs-parser.jay: Add precendence rules for a number of operators
8091 ot reduce the number of shift/reduce conflicts in the grammar.
8093 2001-07-17 Miguel de Icaza <miguel@ximian.com>
8095 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
8098 Get rid of old crufty code.
8100 * rootcontext.cs: Use this to keep track of the parsed
8101 representation and the defined types available to the program.
8103 * gen-treedump.cs: adjust for new convention.
8105 * type.cs: Split out the type manager, and the assembly builder
8108 * typemanager.cs: the type manager will live here now.
8110 * cil-codegen.cs: And the code generator here.
8112 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
8114 * makefile: Fixed up for easy making.
8116 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8118 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
8121 (unary_expression): Expand pre_increment_expression and
8122 post_decrement_expression to reduce a shift/reduce.
8124 2001-07-11 Simon Cozens
8126 * cs-tokenizer.cs: Hex numbers should begin with a 0.
8128 Improve allow_keyword_as_indent name.
8130 2001-06-19 Miguel de Icaza <miguel@ximian.com>
8132 * Adjustments for Beta2.
8134 2001-06-13 Miguel de Icaza <miguel@ximian.com>
8136 * decl.cs: Added `Define' abstract method.
8137 (InTransit): new property, used to catch recursive definitions.
8139 * interface.cs: Implement `Define'.
8141 * modifiers.cs: Map Modifiers.constants to
8142 System.Reflection.TypeAttribute flags.
8144 * class.cs: Keep track of types and user-defined types.
8145 (BuilderInit): New method for creating an assembly
8146 (ResolveType): New function to launch the resolution process, only
8147 used by interfaces for now.
8149 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
8150 that are inserted into the name space.
8152 2001-06-08 Miguel de Icaza <miguel@ximian.com>
8154 * ARGH. I have screwed up my tree so many times due to the use of
8155 rsync rather than using CVS. Going to fix this at once.
8157 * driver.cs: Objetify driver. Load assemblies, use assemblies to
8160 2001-06-07 Miguel de Icaza <miguel@ximian.com>
8162 * Experiment successful: Use System.Type rather that our own
8165 2001-05-25 Miguel de Icaza <miguel@ximian.com>
8167 * cs-parser.jay: Removed nsAliases from here.
8169 Use new namespaces, handle `using XXX;'
8171 * namespace.cs: Reimplemented namespace handling, use a recursive
8172 definition of the class. Now we can keep track of using clauses
8173 and catch invalid using clauses.
8175 2001-05-24 Miguel de Icaza <miguel@ximian.com>
8177 * gen-treedump.cs: Adapted for all the renaming.
8179 * expression.cs (Expression): this class now has a Type property
8180 which returns an expression Type.
8182 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
8183 `Type', as this has a different meaning now in the base
8185 2001-05-22 Miguel de Icaza <miguel@ximian.com>
8187 * interface.cs, class.cs: Removed from all the sources the
8188 references to signature computation, as we can not do method
8189 signature computation during the parsing time, as we are not
8190 trying to solve at that point distinguishing:
8194 void a (NS.Blah x) {}
8197 Which depending on the context might be valid or not, as we do not
8198 know if Blah is the same thing as NS.Blah at that point.
8200 * Redid everything so the code uses TypeRefs now instead of
8201 Types. TypeRefs are just temporary type placeholders, that need
8202 to be resolved. They initially have a pointer to a string and the
8203 current scope in which they are used. This is used later by the
8204 compiler to resolve the reference to an actual Type.
8206 * DeclSpace is no longer a CIR.Type, and neither are
8207 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
8208 are all DeclSpaces, but no Types.
8210 * type.cs (TypeRefManager): This implements the TypeRef manager,
8211 which keeps track of all the types that need to be resolved after
8212 the parsing has finished.
8214 2001-05-13 Miguel de Icaza <miguel@ximian.com>
8216 * ARGH. We are going to have to store `foreach' as a class rather
8217 than resolving it, as we need to verify error 1579 after name
8218 resolution. *OR* we could keep a flag that says `This request to
8219 IEnumerator comes from a foreach statement' which we can then use
8220 to generate the error.
8222 2001-05-10 Miguel de Icaza <miguel@ximian.com>
8224 * class.cs (TypeContainer.AddMethod): we now add methods to the
8225 MethodGroup instead of the method hashtable.
8227 * expression.cs: Add MethodGroup abstraction, which gets us one
8228 step closer to the specification in the way we handle method
8231 * cs-parser.jay (primary_expression): qualified_identifier now
8232 tried to match up an identifier to a local variable reference or
8233 to a parameter reference.
8235 current_local_parameters is now a parser global variable that
8236 points to the current parameters for the block, used during name
8239 (property_declaration): Now creates an implicit `value' argument to
8242 2001-05-09 Miguel de Icaza <miguel@ximian.com>
8244 * parameter.cs: Do not use `param' arguments as part of the
8245 signature, per the spec.
8247 2001-05-08 Miguel de Icaza <miguel@ximian.com>
8249 * decl.cs: Base class for classes, structs and interfaces. This
8250 is the "Declaration Space"
8252 * cs-parser.jay: Use CheckDef for checking declaration errors
8253 instead of having one on each function.
8255 * class.cs: Factor out some code for handling error handling in
8256 accordance to the "Declarations" section in the "Basic Concepts"
8257 chapter in the ECMA C# spec.
8259 * interface.cs: Make all interface member classes derive from
8260 InterfaceMemberBase.
8262 2001-05-07 Miguel de Icaza <miguel@ximian.com>
8264 * Many things: all interfaces are parsed and generated in
8265 gen-treedump. Support for member variables, constructors,
8266 destructors, properties, constants is there.
8268 Beginning of the IL backend, but very little done, just there for
8271 2001-04-29 Miguel de Icaza <miguel@ximian.com>
8273 * cs-parser.jay: Fix labeled statement.
8275 * cs-tokenizer.cs (escape): Escape " and ' always.
8276 ref_line, ref_name: keep track of the line/filename as instructed
8277 by #line by the compiler.
8280 2001-04-27 Miguel de Icaza <miguel@ximian.com>
8282 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
8283 to match the values in System.CodeDOM.
8285 Divid renamed to Divide.
8287 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
8289 (Statements.set): remove.
8291 * System.CodeDOM/CodeCatchClause.cs: always have a valid
8294 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
8295 falseStatements always have valid values.
8297 * cs-parser.jay: Use System.CodeDOM now.
