109 and resolvings from Emit to Resolve.
111 * statement.cs (For): Moved all code that does variable lookups
112 and resolvings from Emit to Resolve.
114 * statement.cs (Using): Moved all code that does variable lookups
115 and resolvings from Emit to Resolve.
117 2002-07-29 Martin Baulig <martin@gnome.org>
119 * attribute.cs (Attribute.Resolve): Explicitly catch a
120 System.NullReferenceException when creating the

186 Fixes bug #24007, added test-152.cs.
188 2002-07-27 Martin Baulig <martin@gnome.org>
190 * expression.cs (Invocation.EmitArguments): When calling a varargs
191 function with only its fixed arguments, we need to pass an empty
194 2002-07-27 Martin Baulig <martin@gnome.org>
196 Mono 0.13 has been released.
198 2002-07-25 Miguel de Icaza <miguel@ximian.com>
200 * driver.cs: Rename --resource to --linkres, because that is what
201 we do currently, we dont support --resource yet.
203 * cs-tokenizer.cs: Fix test for reporting endif mismatches.
205 2002-07-25 Martin Baulig <martin@gnome.org>
207 * class.cs (MethodData): New public class. This is a `method builder'
208 class for a method or one accessor of a Property/Indexer/Event.
209 (MethodData.GetMethodFlags): Moved here from MemberBase.
210 (MethodData.ApplyAttributes): Likewise.
211 (MethodData.ApplyObsoleteAttribute): Likewise.
212 (MethodData.ApplyConditionalAttribute): Likewise.
213 (MethodData.ApplyDllImportAttribute): Likewise.
214 (MethodData.CheckAbstractAndExternal): Likewise.
215 (MethodData.Define): Formerly knows as MemberBase.DefineMethod().
216 (MethodData.Emit): Formerly known as Method.Emit().
217 (MemberBase): Moved everything which was specific to a single
218 accessor/method to MethodData.
219 (Method): Create a new MethodData and call Define() and Emit() on it.
220 (Property, Indexer, Event): Create a new MethodData objects for each
221 accessor and call Define() and Emit() on them.
223 2002-07-25 Martin Baulig <martin@gnome.org>
225 Made MethodCore derive from MemberBase to reuse the code from there.
226 MemberBase now also checks for attributes.
228 * class.cs (MethodCore): Derive from MemberBase, not MemberCore.
229 (MemberBase.GetMethodFlags): Moved here from class Method and marked
231 (MemberBase.DefineAccessor): Renamed to DefineMethod(), added

234 attributes to a method or accessor.
235 (MemberBase.ApplyObsoleteAttribute): New protected virtual method.
236 (MemberBase.ApplyConditionalAttribute): Likewise.
237 (MemberBase.ApplyDllImportAttribute): Likewise.
238 (MemberBase.CheckAbstractAndExternal): Likewise.

243 initialize ParameterTypes and ParameterInfo.
244 (Method.GetReturnType): We can now simply return the MemberType.
245 (Method.GetMethodFlags): Override the MemberBase version and add
246 the conditional flags.
247 (Method.CheckBase): Moved some code from Define() here, call
248 DoDefineParameters() here.
249 (Method.Define): Use DoDefine() and DefineMethod() from MemberBase
250 here to avoid some larger code duplication.
251 (Property.Emit, Indexer.Emit): Call CheckAbstractAndExternal() to
252 ensure that abstract and external accessors don't declare a body.
254 * attribute.cs (Attribute.GetValidPieces): Make this actually work:
255 `System.Attribute.GetCustomAttributes (attr.Type)' does a recursive
256 lookup in the attribute's parent classes, so we need to abort as soon
257 as we found the first match.
258 (Attribute.Obsolete_GetObsoleteMessage): Return the empty string if
259 the attribute has no arguments.
261 * typemanager.cs (TypeManager.AddMethod): Now takes a MemberBase instead
264 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
266 * cs-parser.jay: reverted previous patch.
268 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
270 * cs-parser.jay: fixed bug #22119.
272 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
274 * attribute.cs: fixed compilation. The error was:
275 "attribute.cs(571,17): error CS0177: The out parameter 'is_error' must
276 be assigned to before control leaves the current method."
277 [FIXME: Filed as bug #28186: MCS must report this error.]
279 2002-07-25 Martin Baulig <martin@gnome.org>
281 * attribute.cs (Attribute.Conditional_GetConditionName): New static
282 method to pull the condition name ouf of a Conditional attribute.
283 (Attribute.Obsolete_GetObsoleteMessage): New static method to pull
284 the obsolete message and error flag out of an Obsolete attribute.
286 * class.cs (Method.GetMethodFlags): New public method to get the
287 TypeManager.MethodFlags for this method.
288 (Method.ApplyConditionalAttribute, Method.ApplyObsoleteAttribute): New
290 (Method.Define): Get and apply the Obsolete and Conditional attributes;
291 if we're overriding a virtual function, set the new private variable
292 `parent_method'; call the new TypeManager.AddMethod().
294 * typemanager.cs (TypeManager.AddMethod): New static method. Stores
295 the MethodBuilder and the Method in a PtrHashtable.
296 (TypeManager.builder_to_method): Added for this purpose.
297 (TypeManager.MethodFlags): Added IsObsoleteError.
298 (TypeManager.GetMethodFlags): Added `Location loc' argument. Lookup
299 Obsolete and Conditional arguments in MethodBuilders. If we discover
300 an Obsolete attribute, emit an appropriate warning 618 / error 619 with
301 the message from the attribute.
303 2002-07-24 Martin Baulig <martin@gnome.org>
305 * cs-tokenizer.cs: Eat up trailing whitespaces and one-line comments in
306 preprocessor directives, ensure that the argument to #define/#undef is
307 exactly one identifier and that it's actually an identifier.
309 Some weeks ago I did a `#define DEBUG 1' myself and wondered why this
312 2002-07-24 Martin Baulig <martin@gnome.org>
314 * statement.cs (Foreach.ForeachHelperMethods): Added `Type element_type',
315 initialize it to TypeManager.object_type in the constructor.
316 (Foreach.GetEnumeratorFilter): Set `hm.element_type' to the return type
317 of the `hm.get_current' method if we're using the collection pattern.
318 (Foreach.EmitCollectionForeach): Use `hm.element_type' as the source type
319 for the explicit conversion to make it work when we're using the collection
320 pattern and the `Current' property has a different return type than `object'.
323 2002-07-24 Martin Baulig <martin@gnome.org>
325 * delegate.cs (Delegate.VerifyMethod): Simply return null if the method
326 does not match, but don't report any errors. This method is called in
327 order for all methods in a MethodGroupExpr until a matching method is
328 found, so we don't want to bail out if the first method doesn't match.
329 (NewDelegate.DoResolve): If none of the methods in the MethodGroupExpr
330 matches, report the 123. Fixes #28070.
332 2002-07-24 Martin Baulig <martin@gnome.org>
334 * expression.cs (ArrayAccess.EmitStoreOpcode): Moved the
335 TypeManager.TypeToCoreType() to the top of the method so the
336 following equality checks will work. Fixes #28107.
338 2002-07-24 Martin Baulig <martin@gnome.org>
340 * cfold.cs (ConstantFold.DoConstantNumericPromotions): "If either
341 operand is of type uint, and the other operand is of type sbyte,
342 short or int, the operands are converted to type long." -
343 Actually do what this comment already told us. Fixes bug #28106,
346 2002-07-24 Martin Baulig <martin@gnome.org>
348 * class.cs (MethodBase): New abstract class. This is now a base
349 class for Property, Indexer and Event to avoid some code duplication
350 in their Define() and DefineMethods() methods.
351 (MethodBase.DoDefine, MethodBase.DefineAccessor): Provide virtual
352 generic methods for Define() and DefineMethods().
353 (FieldBase): Derive from MemberBase, not MemberCore.
354 (Property): Derive from MemberBase, not MemberCore.
355 (Property.DefineMethod): Moved all the code from this method to the
356 new MethodBase.DefineAccessor(), just call it with appropriate
358 (Property.Define): Call the new Property.DoDefine(), this does some
359 sanity checks and we don't need to duplicate the code everywhere.
360 (Event): Derive from MemberBase, not MemberCore.
361 (Event.Define): Use the new MethodBase.DefineAccessor() to define the
362 accessors, this will also make them work with interface events.
363 (Indexer): Derive from MemberBase, not MemberCore.
364 (Indexer.DefineMethod): Removed, call MethodBase.DefineAccessor() insstead.
365 (Indexer.Define): Use the new MethodBase functions.
367 * interface.cs (InterfaceEvent.InterfaceEvent): Added `Location loc'
368 argument to the constructor.
369 (Interface.FindMembers): Added support for interface events.
370 (Interface.PopluateEvent): Implemented.
372 Added test-149.cs for this. This also fixes bugs #26067 and #24256.
374 2002-07-22 Miguel de Icaza <miguel@ximian.com>
376 * class.cs (TypeContainer.AddMethod): Adding methods do not use IsValid,
377 but this is required to check for a method name being the same as
378 the containing class.
382 2002-07-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
384 * interface.cs: initialize variable.
386 2002-07-23 Martin Baulig <martin@gnome.org>
388 Implemented the IndexerName attribute in interfaces.
390 * class.cs (TypeContainer.DefineIndexers): Don't set the indexer
391 name if this is an explicit interface implementation.
392 (Indexer.InterfaceIndexerName): New public variable. If we're
393 implementing an interface indexer, this is the IndexerName in that
394 interface. Otherwise, it's the IndexerName.
395 (Indexer.DefineMethod): If we're implementing interface indexer,
396 set InterfaceIndexerName. Use the new Pending.IsInterfaceIndexer
397 and Pending.ImplementIndexer methods.
398 (Indexer.Define): Also define the PropertyBuilder if we're
399 implementing an interface indexer and this is neither an explicit
400 interface implementation nor do the IndexerName match the one in
403 * pending.cs (TypeAndMethods): Added `MethodInfo [] need_proxy'.
404 If a method is defined here, then we always need to create a proxy
405 for it. This is used when implementing interface indexers.
406 (Pending.IsInterfaceIndexer): New public method.
407 (Pending.ImplementIndexer): New public method.
408 (Pending.InterfaceMethod): Added `MethodInfo need_proxy' argument.
409 This is used when implementing interface indexers to define a proxy
411 (Pending.VerifyPendingMethods): Look in the `need_proxy' array and
412 define a proxy if necessary.
414 * interface.cs (Interface.IndexerName): New public variable.
415 (Interface.PopulateIndexer): Set the IndexerName.
416 (Interface.DefineIndexers): New private method. Populate all the
417 indexers and make sure their IndexerNames match.
419 * typemanager.cs (IndexerPropertyName): Added support for interface
422 2002-07-22 Martin Baulig <martin@gnome.org>
424 * codegen.cs (EmitContext.HasReturnLabel): New public variable.
425 (EmitContext.EmitTopBlock): Always mark the ReturnLabel and emit a
426 ret if HasReturnLabel.
427 (EmitContext.TryCatchLevel, LoopBeginTryCatchLevel): New public
430 * statement.cs (Do.Emit, While.Emit, For.Emit, Foreach.Emit): Save
431 and set the ec.LoopBeginTryCatchLevel.
432 (Try.Emit): Increment the ec.TryCatchLevel while emitting the block.
433 (Continue.Emit): If the ec.LoopBeginTryCatchLevel is smaller than
434 the current ec.TryCatchLevel, the branch goes out of an exception
435 block. In this case, we need to use Leave and not Br.
437 2002-07-22 Martin Baulig <martin@gnome.org>
439 * statement.cs (Try.Emit): Emit an explicit ret after the end of the
440 block unless the block does not always return or it is contained in
441 another try { ... } catch { ... } block. Fixes bug #26506.
442 Added verify-1.cs to the test suite.
444 2002-07-22 Martin Baulig <martin@gnome.org>
446 * statement.cs (Switch.TableSwitchEmit): If we don't have a default,
447 then we do not always return. Fixes bug #24985.
449 2002-07-22 Martin Baulig <martin@gnome.org>
451 * expression.cs (Invocation.OverloadedResolve): Do the BetterFunction()
452 lookup on a per-class level; ie. walk up the class hierarchy until we
453 found at least one applicable method, then choose the best among them.
454 Fixes bug #24463 and test-29.cs.
456 2002-07-22 Martin Baulig <martin@gnome.org>
458 * typemanager.cs (TypeManager.ArrayContainsMethod): Don't check the
459 return types of the methods. The return type is not part of the
460 signature and we must not check it to make the `new' modifier work.
461 Fixes bug #27999, also added test-147.cs.
462 (TypeManager.TypeToCoreType): Added TypeManager.type_type.
464 * expression.cs (Invocation.DoResolve): Call TypeManager.TypeToCoreType()
465 on the method's return type.
467 2002-07-21 Martin Baulig <martin@gnome.org>
469 * assign.cs: Make this work if the rightmost source is a constant and
470 we need to do an implicit type conversion. Also adding a few more tests
471 to test-38.cs which should have caught this.
473 * makefile.gnu: Disable debugging, there's already the mcs-mono2.exe
474 target in the makefile for this. The makefile.gnu is primarily intended
475 for end-users who don't want to debug the compiler.
477 2002-07-21 Martin Baulig <martin@gnome.org>
479 * assign.cs: Improved the Assign class so it can now handle embedded
480 assignments (X = Y = Z = something). As a side-effect this'll now also
481 consume less local variables. test-38.cs now passes with MCS, added
482 a few new test cases to that test.
484 2002-07-20 Martin Baulig <martin@gnome.org>
486 * expression.cs (Binary.EmitBranchable): Emit correct unsigned branch
487 instructions. Fixes bug #27977, also added test-146.cs.
489 2002-07-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
491 * cs-tokenizer.cs: fixed getHex ().
493 2002-07-19 Martin Baulig <martin@gnome.org>
495 * expression.cs (Invocation.EmitParams): Use TypeManager.LookupType(),
496 not Type.GetType() to lookup the array type. This is needed when
497 we're constructing an array of a user-defined type.
498 (ArrayAccess.EmitDynamicInitializers): Only emit the Ldelema for
499 single-dimensional arrays, but also for single-dimensial arrays of
502 2002-07-19 Martin Baulig <martin@gnome.org>
504 * expression.cs (New.DoEmit): Create a new LocalTemporary each time
505 this function is called, it's not allowed to share LocalBuilders
508 2002-07-19 Martin Baulig <martin@gnome.org>
510 * expression.cs (Argument.Resolve): Report an error 118 when trying
511 to pass a type as argument.
513 2002-07-18 Martin Baulig <martin@gnome.org>
515 * ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
516 Conv_R_Un for the signed `long' type.
518 2002-07-15 Miguel de Icaza <miguel@ximian.com>
520 * expression.cs (MemberAccess.DoResolve): Do not reuse the field
521 `expr' for the temporary result, as that will fail if we do
522 multiple resolves on the same expression.
524 2002-07-05 Miguel de Icaza <miguel@ximian.com>
526 * ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
527 ec.TypeContainer for looking up aliases.
529 * class.cs (TypeContainer): Remove LookupAlias from here.
531 * decl.cs (DeclSpace); Move here.
533 2002-07-01 Miguel de Icaza <miguel@ximian.com>
535 * class.cs (FindMembers): Only call filter if the constructor
538 Also handle delegates in `NestedTypes' now. Now we will perform
539 type lookups using the standard resolution process. This also
542 * decl.cs (DeclSpace.ResolveType): New type resolution routine.
543 This uses Expressions (the limited kind that can be parsed by the
544 tree) instead of strings.
546 * expression.cs (ComposedCast.ToString): Implement, used to flag
547 errors since now we have to render expressions.
549 (ArrayCreation): Kill FormElementType. Use ComposedCasts in
552 * ecore.cs (SimpleName.ToString): ditto.
554 * cs-parser.jay: Instead of using strings to assemble types, use
555 Expressions to assemble the type (using SimpleName, ComposedCast,
556 MemberAccess). This should fix the type lookups in declarations,
557 because we were using a different code path for this.
559 * statement.cs (Block.Resolve): Continue processing statements
560 even when there is an error.
562 2002-07-17 Miguel de Icaza <miguel@ximian.com>
564 * class.cs (Event.Define): Also remove the `remove' method from
565 the list of pending items.
567 * expression.cs (ParameterReference): Use ldarg.N (0..3) to
568 generate more compact code.
570 2002-07-17 Martin Baulig <martin@gnome.org>
572 * const.cs (Const.LookupConstantValue): Add support for constant
573 `unchecked' and `checked' expressions.
574 Also adding test case test-140.cs for this.
576 2002-07-17 Martin Baulig <martin@gnome.org>
578 * statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
579 check whether mi.ReturnType implements the IEnumerator interface; the
580 `==' and the IsAssignableFrom() will fail in this situation.
582 2002-07-16 Ravi Pratap <ravi@ximian.com>
584 * ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix
587 2002-07-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
589 * expression.cs: fixed bug #27811.
591 2002-07-14 Miguel de Icaza <miguel@ximian.com>
593 * expression.cs (ParameterReference.AddressOf): Patch from Paolo
594 Molaro: when we are a ref, the value already contains a pointer
595 value, do not take the address of it.
597 2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
598 * removed mb-parser.jay and mb-tokenizer.cs
600 Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
602 * expression.cs: check against the building corlib void type.
604 Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
606 * ecore.cs: fix for valuetype static readonly fields: when
607 initializing them, we need their address, not the address of a copy.
609 Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
611 * typemanager.cs: register also enum_type in corlib.
613 Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
615 * class.cs: allow calling this (but not base) initializers in structs.
617 Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
619 * ecore.cs: make sure we compare against the building base types
622 Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
624 * typemanager.cs: fix TypeToCoreType() to handle void and object
625 (corlib gets no more typerefs after this change).
627 2002-07-12 Miguel de Icaza <miguel@ximian.com>
629 * expression.cs (ArrayCreation.EmitArrayArguments): use
630 Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
632 (ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
633 Conv_Ovf_I_Un for the array arguments. Even if C# allows longs as
634 array indexes, the runtime actually forbids them.
636 * ecore.cs (ExpressionToArrayArgument): Move the conversion code
637 for array arguments here.
639 * expression.cs (EmitLoadOpcode): System.Char is a U2, use that
640 instead of the default for ValueTypes.
642 (New.DoEmit): Use IsValueType instead of
643 IsSubclassOf (value_type)
644 (New.DoResolve): ditto.
645 (Invocation.EmitCall): ditto.
647 * assign.cs (Assign): ditto.
649 * statement.cs (Unsafe): Ok, so I got the semantics wrong.
650 Statements *are* currently doing part of their resolution during
653 Expressions do always resolve during resolve, but statements are
654 only required to propagate resolution to their children.
656 2002-07-11 Miguel de Icaza <miguel@ximian.com>
658 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
660 (LoadAssembly): Do not add the dll if it is already specified
662 (MainDriver): Add the System directory to the link path at the end,
663 after all the other -L arguments.
665 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
666 wrong opcode for loading bytes and bools (ldelem.i1 instead of
667 ldelem.u1) and using the opposite for sbytes.
669 This fixes Digger, and we can finally run it.
671 * driver.cs (UnixParseOption): Move the option parsing here.
672 (CSCParseOption): Implement CSC-like parsing of options.
674 We now support both modes of operation, the old Unix way, and the
675 new CSC-like way. This should help those who wanted to make cross
678 The only thing broken is that /r:, /reference: and /lib: are not
679 implemented, because I want to make those have the same semantics
680 as the CSC compiler has, and kill once and for all the confussion
681 around this. Will be doing this tomorrow.
683 * statement.cs (Unsafe.Resolve): The state is checked during
684 resolve, not emit, so we have to set the flags for IsUnsfe here.
686 2002-07-10 Miguel de Icaza <miguel@ximian.com>
688 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
689 not catch the Error_ObjectRefRequired in SimpleName (as it is
690 possible to have a class/instance variable name that later gets
691 deambiguated), we have to check this here.
693 2002-07-10 Ravi Pratap <ravi@ximian.com>
695 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
696 make static and put into Expression.
698 (Event.Define): Register the private field of the event with the
699 TypeManager so that GetFieldFromEvent can get at it.
701 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
702 keep track of the private field associated with an event which
705 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
708 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
710 2002-07-10 Miguel de Icaza <miguel@ximian.com>
712 * expression.cs (Binary.EmitBranchable): this routine emits the
713 Binary expression in a branchable context. This basically means:
714 we need to branch somewhere, not just get the value on the stack.
716 This works together with Statement.EmitBoolExpression.
718 * statement.cs (Statement.EmitBoolExpression): Use
721 2002-07-09 Miguel de Icaza <miguel@ximian.com>
723 * statement.cs (For): Reduce the number of jumps in loops.
725 (For): Implement loop inversion for the For statement.
727 (Break): We can be breaking out of a Try/Catch controlled section
728 (foreach might have an implicit try/catch clause), so we need to
729 use Leave instead of Br.
731 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
732 now). If the instace expression supports IMemoryLocation, we use
733 the AddressOf method from the IMemoryLocation to extract the
734 address instead of emitting the instance.
736 This showed up with `This', as we were emitting the instance
737 always (Emit) instead of the Address of This. Particularly
738 interesting when This is a value type, as we dont want the Emit
739 effect (which was to load the object).
741 2002-07-08 Miguel de Icaza <miguel@ximian.com>
743 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
745 * statement.cs (Checked): Set the CheckedState during the resolve
746 process too, as the ConvCast operations track the checked state on
747 the resolve process, and not emit.
749 * cs-parser.jay (namespace_member_declaration): Flag that we have
750 found a declaration when we do. This is used to flag error 1529
752 * driver.cs: Report ok when we display the help only.
754 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
756 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
758 2002-07-04 Miguel de Icaza <miguel@ximian.com>
760 * cs-tokenizer.cs (define): We also have to track locally the
761 defines. AllDefines is just used for the Conditional Attribute,
762 but we also need the local defines for the current source code.
764 2002-07-03 Miguel de Icaza <miguel@ximian.com>
766 * statement.cs (While, For, Do): These loops can exit through a
767 Break statement, use this information to tell whether the
768 statement is the last piece of code.
770 (Break): Flag that we break.
772 * codegen.cs (EmitContexts): New `Breaks' state variable.
774 2002-07-03 Martin Baulig <martin@gnome.org>
776 * class.cs (TypeContainer.MethodModifiersValid): Allow override
777 modifiers in method declarations in structs. Otherwise, you won't
778 be able to override things like Object.Equals().
780 2002-07-02 Miguel de Icaza <miguel@ximian.com>
782 * class.cs (Method, Property, Indexer): Do not allow the public
783 modifier to be used in explicit interface implementations.
785 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
786 override modifiers in method declarations in structs
788 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
790 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
791 integer or real overflow, report an error
793 2002-07-02 Martin Baulig <martin@gnome.org>
795 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
796 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
797 to tell the runtime about our newly created System.Object and
798 System.ValueType types.
800 2002-07-02 Miguel de Icaza <miguel@ximian.com>
802 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
803 struct instead of Ldarg/Starg.
805 2002-07-02 Martin Baulig <martin@gnome.org>
807 * expression.cs (Indirection.Indirection): Call
808 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
810 2002-07-02 Martin Baulig <martin@gnome.org>
812 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
813 ValueType, call TypeManager.TypeToCoreType() on it.
814 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
815 the OpCodes.Newarr argument.
817 2002-07-02 Martin Baulig <martin@gnome.org>
819 * expression.cs (Invocation.EmitCall): When compiling corlib,
820 replace all calls to the system's System.Array type to calls to
821 the newly created one.
823 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
824 System.Array methods.
825 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
826 from the system's System.Array type which must be replaced.
828 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
830 * typemanager.cs: load unverifiable_code_ctor so we can build
831 corlib using the correct type. Avoid using GetTypeCode() with
833 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
834 TypeManager.object_type to allow building corlib.
836 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
838 * ecore.cs: handle System.Enum separately in LoadFromPtr().
840 2002-07-01 Martin Baulig <martin@gnome.org>
842 * class.cs: Make the last change actually work, we need to check
843 whether `ifaces != null' to avoid a crash.
845 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
847 * class.cs: when we build structs without fields that implement
848 interfaces, we need to add the interfaces separately, since there is
849 no API to both set the size and add the interfaces at type creation
852 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
854 * expression.cs: the dimension arguments to the array constructors
855 need to be converted if they are a long.
857 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
859 * class.cs: don't emit ldarg.0 if there is no parent constructor
860 (fixes showstopper for corlib).
862 2002-06-29 Martin Baulig <martin@gnome.org>
864 MCS now compiles corlib on GNU/Linux :-)
866 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
867 ie. check for MethodImplOptions.InternalCall.
869 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
870 and TypeManager.attribute_type are null, so we must explicitly check
871 whether parent is not null to find out whether it's an attribute type.
872 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
873 and SetBuilder, not only if the property is neither abstract nor external.
874 This is necessary to set the MethodImplOptions on the accessor methods.
875 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
876 SetBuilder, see Property.Emit().
878 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
879 populate "System.Object", "System.ValueType" and "System.Attribute" since
880 they've already been populated from BootCorlib_PopulateCoreTypes().
882 2002-06-29 Martin Baulig <martin@gnome.org>
884 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
885 is the NullLiteral, we also need to make sure that target_type is not
888 2002-06-29 Martin Baulig <martin@gnome.org>
890 * rootcontext.cs (RootContext.ResolveCore): We must initialize
891 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
892 before calling BootstrapCorlib_ResolveDelegate ().
894 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
896 * statement.cs: fixed build-breaker. All tests passed ok.
898 2002-06-27 Martin Baulig <martin@gnome.org>
900 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
901 for System.Decimal when compiling corlib.
903 2002-06-27 Martin Baulig <martin@gnome.org>
905 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
906 switch blocks which contain nothing but a default clause.
908 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
910 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
912 2002-06-27 Martin Baulig <martin@gnome.org>
914 * ecore.cs (PropertyExpr.PropertyExpr): Call
915 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
917 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
918 is already a TypeBuilder.
920 2002-06-27 Martin Baulig <martin@gnome.org>
922 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
923 `target_type == TypeManager.array_type', not IsAssignableFrom() in
924 the "from an array-type to System.Array" case. This makes it work
925 when compiling corlib.
927 2002-06-27 Martin Baulig <martin@gnome.org>
929 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
930 non-static PropertyExpr, set its InstanceExpression. This makes
931 the `ICollection.Count' property work in System/Array.cs.
933 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
935 * driver.cs: Made error handling more consistent. Errors now
936 tracked by Report class, so many methods which used to return int
937 now return void. Main() now prints success/failure and
938 errors/warnings message.
940 Renamed '--probe' compiler argument to '--expect-error'. Removed
941 the magic number return values (123 and 124). Now, if the
942 expected error occurs, the compiler exits with success (exit value
943 0). If the compilation completes without seeing that particular
944 error, the compiler exits with failure (exit value 1). The
945 makefile in mcs/errors has been changed to handle the new behaviour.
947 * report.cs: Made 'expected error' number a property and renamed
948 it from 'Probe' to 'ExpectedError'.
950 * genericparser.cs: Removed error handling support, since it is
951 now all done by Report class.
953 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
954 class, so parse() no longer returns an int.
956 * namespace.cs: Use Report.Error instead of GenericParser.error
958 2002-06-22 Miguel de Icaza <miguel@ximian.com>
960 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
961 TypeContainer.AddOperator): At the front of the list put the
962 explicit implementations, so they get resolved/defined first.
964 2002-06-21 Miguel de Icaza <miguel@ximian.com>
966 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
967 interface type is implemented by this TypeContainer. Used during
968 explicit interface implementation.
970 (Property.Define, Indexer.Define, Method.Define): Validate that
971 the given interface in the explicit implementation is one of the
972 base classes for the containing type.
974 Also if we are explicitly implementing an interface, but there is
975 no match in the pending implementation table, report an error.
977 (Property.Define): Only define the property if we are
978 not explicitly implementing a property from an interface. Use the
979 correct name also for those properties (the same CSC uses,
980 although that is really not needed).
982 (Property.Emit): Do not emit attributes for explicitly implemented
983 properties, as there is no TypeBuilder.
985 (Indexer.Emit): ditto.
987 Hiding then means that we do not really *implement* a pending
988 implementation, which makes code fail.
990 2002-06-22 Martin Baulig <martin@gnome.org>
992 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
993 the return value of Object.GetType(). [FIXME: we need to do this whenever
994 we get a type back from the reflection library].
996 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
998 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
1000 2002-06-20 Miguel de Icaza <miguel@ximian.com>
1002 * attribute.cs: Return null if we can not look up the type.
1004 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
1005 the interface types found.
1007 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
1008 interface types found.
1010 * typemanager.cs (GetInterfaces): Make this routine returns alll
1011 the interfaces and work around the lame differences between
1012 System.Type and System.Reflection.Emit.TypeBuilder in the results
1013 result for GetInterfaces.
1015 (ExpandInterfaces): Given an array of interface types, expand and
1016 eliminate repeated ocurrences of an interface. This expands in
1017 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
1020 2002-06-21 Martin Baulig <martin@gnome.org>
1022 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
1025 2002-06-21 Martin Baulig <martin@gnome.org>
1027 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
1028 and called with one of the core types, return the corresponding typebuilder for
1031 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
1034 2002-06-21 Martin Baulig <martin@gnome.org>
1036 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
1037 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
1038 (Expression.ConvertReferenceExplicit): Likewise.
1040 * expression.cs (ElementAccess.DoResolve): Likewise.
1041 (ElementAccess.DoResolveLValue): Likewise.
1043 2002-06-10 Martin Baulig <martin@gnome.org>
1045 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
1046 add the "value" parameter to the parameter list.
1048 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
1051 2002-06-19 Miguel de Icaza <miguel@ximian.com>
1053 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
1054 the argument to an int, uint, long or ulong, per the spec. Also
1055 catch negative constants in array creation.
1057 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
1059 * class.cs: do not allow the same interface to appear twice in
1060 the definition list.
1062 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
1064 * ecore.cs: don't use ldlen with System.Array.
1066 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
1068 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
1070 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
1072 * modifiers.cs: produce correct field attributes for protected
1073 internal. Easy fix so miguel can work on ther harder stuff:-)
1075 2002-06-18 Miguel de Icaza <miguel@ximian.com>
1077 * pending.cs: New file. Move the code from class.cs here.
1078 Support clearning the pending flag for all methods (when not doing
1079 explicit interface implementation).
1081 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
1083 * rootcontext.cs: added a couple more types needed to bootstrap.
1085 2002-06-17 Miguel de Icaza <miguel@ximian.com>
1087 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
1088 constructor in the type, instead of any constructor in the type
1089 hierarchy. Thanks to Paolo for finding this bug (it showed up as
1090 a bug in the Mono runtime when applying the params attribute).
1092 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1093 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
1095 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
1097 * expression.cs (Unary.ResolveOperator): Use TypeManager
1098 to resolve the type.
1100 2002-06-13 Ravi Pratap <ravi@ximian.com>
1102 * cs-parser.jay (enum_member_declaration): Pass in the attributes
1105 * enum.cs (AddEnumMember): Add support to store the attributes associated
1106 with each member too.
1108 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
1109 field builders too - this takes care of the enum member case.
1111 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
1113 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
1114 address-of operator on both value types and pointers.
1116 2002-06-10 Martin Baulig <martin@gnome.org>
1118 * interface.cs (Interface.PopulateIndexer): Add the indexer's
1119 PropertyBuilder to the `property_builders' list.
1121 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
1122 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
1123 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
1124 find any indexers which are inherited from an interface.
1126 2002-06-09 Martin Baulig <martin@gnome.org>
1128 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
1129 the same type as the constant if necessary. There's also a test-130.cs
1132 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
1134 * typemanager.cs (TypeManager.ChangeType): Previously known as
1135 Enum.ChangeEnumType().
1137 2002-06-09 Martin Baulig <martin@gnome.org>
1139 * expression.cs (Cast.TryReduce): Added support for consts.
1141 2002-06-08 Ravi Pratap <ravi@ximian.com>
1143 * class.cs (Accessor): Hold attributes information so we can pass
1146 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
1147 Modify to pass in attributes attached to the methods.
1149 (add_accessor_declaration, remove_accessor_declaration): Ditto.
1151 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
1152 to handle the Accessor kind :-)
1154 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
1156 2002-06-08 Martin Baulig <martin@gnome.org>
1158 * expression.cs (Unary.TryReduceNegative): Added support for
1161 2002-06-08 Martin Baulig <martin@gnome.org>
1163 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
1164 name can't be found in the `defined_names' - the caller will do a
1165 MemberLookup in this case and thus find methods in System.Enum
1166 such as Enum.IsDefined().
1168 2002-06-08 Martin Baulig <martin@gnome.org>
1170 * enum.cs (Enum.ChangeEnumType): This is a custom version of
1171 Convert.ChangeType() which works with TypeBuilder created types.
1172 (Enum.LookupEnumValue, Enum.Define): Use it here.
1174 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
1175 `TypeBuilder.BaseType != null' check.
1176 (TypeContainer.FindMembers): Only lookup parent members if we
1177 actually have a parent.
1178 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
1179 (ConstructorInitializer.Resolve): Likewise.
1181 * interface.cs (Interface.FindMembers): Added
1182 `TypeBuilder.BaseType != null' check.
1184 * rootcontext.cs (RootContext.ResolveCore): Added
1185 "System.Runtime.CompilerServices.IndexerNameAttribute" to
1186 classes_second_stage.
1188 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
1189 debug_type and trace_type when compiling with --nostdlib.
1191 2002-06-07 Martin Baulig <martin@gnome.org>
1193 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
1194 (AddField): Set it to true when adding a non-static field.
1195 (DefineType): Use `have_nonstatic_fields' to find out whether we
1196 have non-static fields, not `Fields != null'.
1198 2002-06-02 Miguel de Icaza <miguel@ximian.com>
1200 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
1201 dereferencing a null on the static-field code path)
1203 2002-05-30 Martin Baulig <martin@gnome.org>
1205 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
1206 to take command line arguments. Use reflection to call the new
1207 custom `Initialize' function on the symbol writer and pass it the
1208 command line arguments.
1210 * driver.cs (--debug-args): New command line argument to pass command
1211 line arguments to the symbol writer.
1213 2002-05-28 Miguel de Icaza <miguel@ximian.com>
1215 * assign.cs (DoResolve): Forgot to do the implicit conversion to
1216 the target type for indexers and properties. Thanks to Joe for
1219 2002-05-27 Miguel de Icaza <miguel@ximian.com>
1221 * typemanager.cs (MethodFlags): returns the method flags
1222 (Obsolete/ShouldIgnore) that control warning emission and whether
1223 the invocation should be made, or ignored.
1225 * expression.cs (Invocation.Emit): Remove previous hack, we should
1226 not do this on matching a base type, we should do this based on an attribute
1228 Only emit calls to System.Diagnostics.Debug and
1229 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
1230 on the command line.
1232 * rootcontext.cs: Global settings for tracing and debugging.
1234 * cs-tokenizer.cs (define): New utility function to track
1235 defines. Set the global settings for TRACE and DEBUG if found.
1237 2002-05-25 Ravi Pratap <ravi@ximian.com>
1239 * interface.cs (Populate*): Pass in the TypeContainer as well as
1240 the DeclSpace as parameters so that we can create EmitContexts and
1241 then use that to apply attributes etc.
1243 (PopulateMethod, PopulateEvent, PopulateProperty)
1244 (PopulateIndexer): Apply attributes everywhere.
1246 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
1249 (ApplyAttributes): Update accordingly.
1251 We now apply interface attributes for all members too.
1253 2002-05-26 Miguel de Icaza <miguel@ximian.com>
1255 * class.cs (Indexer.Define); Correctly check if we are explicit
1256 implementation (instead of checking the Name for a ".", we
1257 directly look up if the InterfaceType was specified).
1259 Delay the creation of the PropertyBuilder.
1261 Only create the PropertyBuilder if we are not an explicit
1262 interface implementation. This means that explicit interface
1263 implementation members do not participate in regular function
1264 lookups, and hence fixes another major ambiguity problem in
1265 overload resolution (that was the visible effect).
1267 (DefineMethod): Return whether we are doing an interface
1270 * typemanager.cs: Temporary hack until we get attributes in
1271 interfaces (Ravi is working on that) and we get IndexerName
1272 support in interfaces.
1274 * interface.cs: Register the indexers as properties.
1276 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
1277 warning, I have verified that this is a bug in the .NET runtime
1278 (JavaScript suffers of the same problem).
1280 * typemanager.cs (MemberLookup): When looking up members for
1281 interfaces, the parent of an interface is the implicit
1282 System.Object (so we succeed in searches of Object methods in an
1283 interface method invocation. Example: IEnumerable x; x.ToString
1286 2002-05-25 Miguel de Icaza <miguel@ximian.com>
1288 * class.cs (Event): Events should also register if they do
1289 implement the methods that an interface requires.
1291 * typemanager.cs (MemberLookup); use the new GetInterfaces
1294 (GetInterfaces): The code used to lookup interfaces for a type is
1295 used in more than one place, factor it here.
1297 * driver.cs: Track the errors at the bottom of the file, we kept
1300 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
1301 instance if the method we are calling is static!
1303 2002-05-24 Miguel de Icaza <miguel@ximian.com>
1305 * attribute.cs (ApplyAttributes): Make this function filter out
1306 the IndexerName attribute (as that attribute in reality is never
1307 applied) and return the string constant for the IndexerName
1310 * class.cs (TypeContainer.Emit): Validate that all the indexers
1311 have the same IndexerName attribute, and if so, set the
1312 DefaultName attribute on the class.
1314 * typemanager.cs: The return value might contain other stuff (not
1315 only methods). For instance, consider a method with an "Item"
1316 property and an Item method.
1318 * class.cs: If there is a problem with the parameter types,
1321 2002-05-24 Ravi Pratap <ravi@ximian.com>
1323 * ecore.cs (ImplicitConversionExists): Wrapper function which also
1324 looks at user defined conversion after making a call to
1325 StandardConversionExists - we need this for overload resolution.
1327 * expression.cs : Update accordingly the various method calls.
1329 This fixes 2 bugs filed against implicit user defined conversions
1331 2002-05-22 Miguel de Icaza <miguel@ximian.com>
1333 * statement.cs: Track the result of the assignment.
1335 2002-05-21 Miguel de Icaza <miguel@ximian.com>
1337 * expression.cs (MemberAccess): Improved error reporting for
1338 inaccessible members.
1340 2002-05-22 Martin Baulig <martin@gnome.org>
1342 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
1343 itself with debugging support.
1345 2002-05-22 Martin Baulig <martin@gnome.org>
1347 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
1348 Removed, this isn't needed anymore.
1350 2002-05-20 Martin Baulig <martin@gnome.org>
1352 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
1353 be underlying type for an enum.
1355 2002-05-20 Miguel de Icaza <miguel@ximian.com>
1357 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
1358 that splits out the loading of just the core types.
1360 * rootcontext.cs (ResolveCore): Split the struct resolution in
1361 two, so we can load the enumeration underlying types before any
1364 * expression.cs (Is): Bandaid until we fix properly Switch (see
1365 bug #24985 for details).
1367 * typemanager.cs (ImplementsInterface): The hashtable will contain
1368 a null if there are no interfaces implemented.
1370 2002-05-18 Miguel de Icaza <miguel@ximian.com>
1372 * cs-parser.jay (indexer_declarator): It is fine to have array
1375 2002-05-17 Miguel de Icaza <miguel@ximian.com>
1377 * typemanager.cs: (RegisterBuilder): New function used to register
1378 TypeBuilders that implement interfaces. Since
1379 TypeBuilder.GetInterfaces (as usual) does not work with lame
1381 (AddUserType): register interfaces.
1383 (ImplementsInterface): Use the builder_to_ifaces hash if we are
1384 dealing with TypeBuilder. Also, arrays are showing up as
1385 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
1386 methods can not be invoked on them!
1388 * ecore.cs (ExplicitReferenceConversionExists): Made public.
1389 (ImplicitReferenceConversionExists): Split out from
1390 StandardConversionExists.
1392 * expression.cs (As): We were only implementing one of the three
1393 cases for the as operator. We now implement them all.
1394 (Is): Implement the various other cases for Is as well.
1396 * typemanager.cs (CACHE): New define used to control if we want or
1397 not the FindMembers cache. Seems to have a negative impact on
1398 performance currently
1400 (MemberLookup): Nested types have full acess to
1401 enclosing type members
1403 Remove code that coped with instance/static returns for events, we
1404 now catch this in RealFindMembers.
1406 (RealFindMembers): only perform static lookup if the instance
1407 lookup did not return a type or an event.
1409 2002-05-17 Miguel de Icaza <miguel@ximian.com>
1411 * assign.cs (CompoundAssign): We pass more semantic information
1412 now to Compound Assignments than we did before: now we have all
1413 the information at hand, and now we resolve the target *before* we
1414 do the expression expansion, which allows the "CacheValue" method
1415 to have the effect we intended (before, a [x] += 1 would generate
1416 two differen ArrayAccess expressions from the ElementAccess,
1417 during the resolution process).
1419 (CompoundAssign.DoResolve): Resolve target and original_source here.
1421 2002-05-16 Miguel de Icaza <miguel@ximian.com>
1423 * expression.cs (ArrayAccess): dropped debugging information.
1425 * typemanager.cs: Small bug fix: I was always returning i_members,
1426 instead of one of i_members or s_members (depending on which had
1429 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
1430 method is invoked before any code generation takes place, and it
1431 is a mechanism to inform that the expression will be invoked more
1432 than once, and that the method should use temporary values to
1433 avoid having side effects
1435 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
1437 * ecore.cs (Expression.CacheTemporaries): Provide empty default
1440 * expression.cs (Indirection, ArrayAccess): Add support for
1441 CacheTemporaries in these two bad boys.
1443 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
1445 (StoreFromPtr): Handle stobj as well.
1447 * expression.cs (UnaryMutator): Share more code.
1449 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
1450 down: I was not tracking the Filter function as well, which
1451 was affecting the results of the cache.
1453 2002-05-15 Miguel de Icaza <miguel@ximian.com>
1455 * attribute.cs: Remove the hack to handle the CharSet property on
1458 2002-05-14 Miguel de Icaza <miguel@ximian.com>
1460 * attribute.cs (DoResolve): More uglyness, we now only try to
1461 resolve the attribute partially, to extract the CharSet
1462 information (only if we are a StructLayout attribute). Otherwise
1464 (GetExtraTypeInfo): Add some code to conditionally kill in the
1465 future this. I am more and more convinced that the .NET
1466 framework has special code to handle the attribute setting on
1469 * expression.cs (IsParamsMethodApplicable): Revert my previous
1470 foreach change here, it was wrong.
1472 2002-05-13 Miguel de Icaza <miguel@ximian.com>
1474 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
1475 (pp_expr): do not abort on unknown input, just return.
1476 (eval): abort if there are pending chars.
1478 * attribute.cs (Attribute.Resolve): Positional parameters are
1479 optional. Deal with that case.
1481 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
1482 the Ansi/Unicode/Auto information for the type.
1484 (TypeContainer.DefineType): instantiate the EmitContext here, as
1485 we will be using it during the type definition (to resolve
1486 attributes) and during the emit phase.
1488 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
1489 to pull type information out of the attributes
1491 (Attribute.Resolve): track the constructor builder, and allow for
1492 multiple invocations (structs and classes will use this).
1494 * ecore.cs (MemberLookupFinal): new version with all the
1495 parameters customizable.
1497 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
1498 constructors. Return if the result value is null (as the error
1499 would have been flagged already by MemberLookupFinal)
1501 Do not allow instances of abstract classes or interfaces to be
1504 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
1505 We have to compare the assembly property here when dealing with
1506 FamANDAssem and Assembly access modifiers, because we might be
1507 creating an assembly from *modules* (that means that we are not
1508 getting TypeBuilders for types defined in other modules that are
1509 part of this assembly).
1511 (Method.Emit): If the method is marked abstract and has a body,
1514 (TypeContainer.DefineMembers): If both the defined member and the
1515 parent name match are methods, then do not emit any warnings: let
1516 the Method.Define routine take care of flagging warnings. But if
1517 there is a mismatch (method overrides something else, or method is
1518 overriwritten by something, then emit warning).
1520 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
1521 set to null, this means `do not check for the return type on the
1524 (Method.Define): set the return type for the method signature to
1525 null, so that we get methods with the same name and parameters and
1526 different return types. This is used to flag warning 114 (you are
1527 hiding a method, and you probably want to use the new/override
1530 * typemanager.cs (MemberLookup): Implemented proper access
1531 control, closing a long standing set of bug reports. The problem
1532 was that the Framework only has two bits: Public and NonPublic,
1533 and NonPublic includes private and protected methods, but we need
1534 to enforce the FamANDAssem, FamOrAssem and Family.
1536 2002-05-11 Miguel de Icaza <miguel@ximian.com>
1538 * statement.cs (GotoCase): Return true: Ammounts to giving up
1539 knowledge on whether we return or not, and letting the other case
1540 be responsible for it.
1542 2002-05-10 Miguel de Icaza <miguel@ximian.com>
1544 * driver.cs: Do not load directories for each file processed, only
1545 do it if there is a pattern.
1547 * ecore.cs: Report readonly assigns here as well, as we might have
1548 been resolved only by MemberAccess.
1550 (SimpleName.SimpleNameResolve): Also be useful for LValue
1551 resolution. We need this to propagate assign to local readonly variables
1553 * typemanager.cs: Use a ptrhashtable for the criteria, because we
1554 do not want to reuse potential criteria memory.
1556 * class.cs (MyEventBuilder): Set reflected_type;
1558 * ecore.cs (Constantify): Added support for constifying bools.
1560 (RootContext.LookupType): Added a cache for values looked up in
1561 the declaration space.
1563 * typemanager.cs (FindMembers): Now is a front-end to
1564 RealFindMembers, and provides a two-level hashtable-based cache to
1567 15% performance improvement: from 22.5 to 19.2 seconds.
1569 * expression.cs (IsParamsMethodApplicable): use foreach.
1570 (Invocation.DoResolve): ditto.
1571 (New.DoResolve): ditto.
1572 (ArrayCreation.DoResolve): ditto.
1574 * ecore.cs (FindMostEncompassingType): use foreach.
1576 * delegate.cs (NewDelegate.DoResolve): Use foreach
1578 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
1579 (RemoveMethods): use foreach.
1581 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
1582 nested foreach statements instead of for, and also break out of
1583 the inner loop once a match is found.
1585 (Invocation.OverloadResolve): Use foreach, simplify the code.
1587 2002-05-08 Miguel de Icaza <miguel@ximian.com>
1589 * cfold.cs (BinaryFold): During an enumeration evaluation context,
1590 we actually unwrap the expression to allow for extra information
1593 * expression.cs: Use Shr_Un on unsigned operations.
1595 2002-05-08 Ravi Pratap <ravi@ximian.com>
1597 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
1598 applicable operators was not being considered correctly. This closes
1599 the bug Miguel reported.
1601 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
1603 * attribute.cs: check that the type derives from System.Attribute
1604 and report the correct error in that case (moved the duplicate code to
1605 its own method, too).
1607 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
1609 * attribute.cs: lookup attribute type name as the spec says: first the
1610 bare attribute name and then name + "Attribute" (nant compiles with
1611 mcs after this fix).
1613 2002-05-07 Miguel de Icaza <miguel@ximian.com>
1615 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
1616 Because of the way we parse things, we should try to see if a
1617 UIntConstant can fit in an integer.
1619 2002-05-07 Ravi Pratap <ravi@ximian.com>
1621 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
1622 when we are in an explicit context.
1624 (ConvertReferenceExplicit): When converting from Iface type S to Class
1625 T make sure the rules are implemented as an OR.
1627 * parameter.cs (ParameterType): Make it a property for now although the
1628 purpose really isn't anything immediate.
1630 * expression.cs (Is*Applicable): Do better checking on the parameter type
1631 of a ref/out parameter. The ones from the system assemblies are already
1632 marked with the correct type so we don't need to do any correction.
1634 * ecore.cs (StandardConversionExists): Conversion from Interface types to
1635 the object type is standard too so include that.
1637 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1639 * ecore.cs (StandardConversionExists): Augment with missing code:
1640 deal with IntConstant, LongConstants and Enumerations.
1642 * assign.cs: Report the error, instead of failing silently
1644 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
1645 typecontainer that they are declared, because the
1646 typecontainer/namespace will have the list of using clauses that
1649 Assembly Attributes were escaping the normal registration
1652 (EmitCode): Apply attributes within an EmitContext that represents
1653 the container they were declared on.
1655 * cs-parser.jay: Track bases for structs. How did I get this wrong?
1657 2002-05-06 Ravi Pratap <ravi@ximian.com>
1659 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
1660 Revamp completely - make much cleaner as we now operate only
1663 (FindMostSpecificSource, FindMostSpecificTarget): New methods
1664 to implement the logic detailed in the spec more correctly.
1666 (UserDefinedConversion): Update accordingly.
1668 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1670 * statement.cs: Return flow analysis information up.
1672 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
1675 (token): Do not consume an extra character before calling
1678 2002-05-06 Piers Haken <piersh@friskit.com>
1680 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
1682 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1684 * class.cs (Constructor.Emit): Set the IsStatic flag in the
1685 EmitContext during the instance constructor initializer
1686 resolution, to stop access to instance variables.
1688 This is mandated by the spec, last paragraph of the `constructor
1689 initializers' section.
1691 2002-05-05 Miguel de Icaza <miguel@ximian.com>
1693 * cs-parser.jay, class.cs (Accessor): new class used to represent
1694 an accessor (get or set). In the past we used `null' to represent
1695 a missing accessor. But this is ambiguous because there was no
1696 way to tell in abstract indexers/properties if one of them was
1699 Now there is a way of addressing that.
1701 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
1702 instead of FindMembers.
1704 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
1705 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
1707 * attribute.cs: Treat indexers and properties as the same in terms
1708 of applying attributes
1710 * ecore.cs (FindMostEncompassedType): Use statically initialized
1711 EmptyExpressions()s like we do elsewhere to avoid creating useless
1712 objects (and we take this out of the tight loop).
1714 (GetConversionOperators): Move the code to extract the actual
1715 operators to a separate routine to clean things up.
1717 2002-05-04 Miguel de Icaza <miguel@ximian.com>
1719 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
1720 events are always registered FieldBuilders.
1722 * class.cs (FieldBase): New class shared by Fields
1724 * delegate.cs: If we are a toplevel delegate, use our full name.
1725 If we are a nested delegate, then only use our tail name.
1727 2002-05-02 Ravi Pratap <ravi@ximian.com>
1729 * expression.cs (IsApplicable): Ensure that we add the "&" to
1730 ref/out types before comparing it with the type of the argument.
1732 (IsParamsMethodApplicable): Ditto.
1734 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
1737 * delegate.cs : Handle the case when we have more than one applicable
1738 method. Flag an error only when we finish checking all.
1740 2002-05-02 Miguel de Icaza <miguel@ximian.com>
1742 * expression.cs: Add support for boolean static initializers.
1744 2002-05-01 Miguel de Icaza <miguel@ximian.com>
1746 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
1748 * parameter.cs (ComputeParameterTypes,
1749 ComputeAndDefineParameterTypes): Better error handling: now we
1750 clear the `types' cache if we fail during any of the type lookups.
1751 We also return the status code correctly to our caller
1753 * delegate.cs: If we fail to define a delegate, abort the extra
1756 * expression.cs (Binary.ResolveOperator): for
1757 operator==(object,object) and operator !=(object, object) we also
1758 have to verify that there is an implicit conversion from one to
1761 (ArrayAccess.DoResolve): Array Access can operate on
1764 2002-04-30 Miguel de Icaza <miguel@ximian.com>
1766 * assign.cs (CompoundAssign): A new class used as a "flag" that
1767 the assignment actually is happening as part of a compound
1768 assignment operator.
1770 During compound assignment, a few new rules exist to enable things
1777 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
1778 to the type of x) if y is implicitly convertible to the type of x,
1779 and the operator is a builtin operator and the return type of the
1780 operator is explicitly convertible to the type of x.
1782 * rootcontext.cs: Reset warning level to 2. 4 catches various
1783 "interesting" features in mcs, we must clean this up at some
1784 point, but currently am trying to kill other bugs ;-)
1786 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
1787 in container classes as well.
1789 * expression.cs (Binary.ResolveOperator): Handle string case
1790 before anything else (as operator overloading does emit an error
1791 before doing anything else).
1793 This code could go away when we move to a table driven model, but
1794 i could not come up with a good plan last night.
1796 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
1798 * typemanager.cs (CSharpName): reimplementation using regex.
1799 * class.cs: added null check for fields in Emit
1800 * rootcontext.cs: set warninglevel to 4
1802 2002-04-29 Miguel de Icaza <miguel@ximian.com>
1804 * typemanager.cs (CSharpName): reimplemented with Lupus
1807 2002-04-28 Miguel de Icaza <miguel@ximian.com>
1809 * statement.cs (If): correclty implement Resolve, because we were
1810 not catching sem errors in there. The same process is needed
1812 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
1815 (Statement.Warning_DeadCodeFound): Factorize code.
1816 (While): Report dead code here too.
1818 (Statement): Added Resolve virtual method to allow
1819 for resolution split from the emit code.
1821 2002-04-26 Miguel de Icaza <miguel@ximian.com>
1823 * statement.cs (EmitBoolExpression): No longer try to resolve the
1825 (MakeBoolean): New utility function that resolve, implicitly
1826 converts to boolean and tags the expression.
1829 (If, Do): Implement dead code elimination.
1830 (While): Implement loop inversion
1832 (Do, While, For, If): Resolve the expression prior to calling our
1835 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
1838 - added method Report28 (warning: program has more than one entry point)
1839 - added method IsEntryPoint, implements paragraph 10.1 of the spec
1840 - modified method Method.Define, the part at the end of the method
1842 * rootcontext.cs: added static public Location EntryPointLocation;
1844 * ../errors/cs0028.cs : Add test case for the above warning.
1847 - modified method CSharpName to allow arrays of primitive type to
1848 be printed nicely (e.g. instead of System.Int32[][] it now prints
1850 - added method CSharpSignature: returns the signature of a method
1851 in string format to be used in reporting errors, warnings, etc.
1853 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
1856 2002-04-26 Ravi Pratap <ravi@ximian.com>
1858 * delegate.cs (Define): Fix extremely silly bug where I was
1859 setting the type of the 'object' parameter of the BeginInvoke
1860 method to System.IAsyncResult instead of System.Object ;-)
1862 2002-04-26 Miguel de Icaza <miguel@ximian.com>
1864 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
1867 (Constructor.Emit): return if we fail to initialize the
1868 constructor. Another door closed!
1870 * expression.cs (New.DoResolve): Improve error message (from -6 to
1871 1501). Use DeclaredOnly lookup to find the exact constructor.
1873 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
1874 loop. This is useful.
1876 * cs-parser.jay: Adjust the default parameters so that destructors
1877 have the proper signature.
1879 2002-04-26 Martin Baulig <martin@gnome.org>
1881 * driver.cs (LoadAssembly): If `assembly' contains any characters
1882 which are only valid in path names and not in assembly names
1883 (currently slash, backslash and point), use Assembly.LoadFrom ()
1884 instead of Assembly.Load () on the `assembly' (before iteration
1885 over the link_paths).
1887 2002-04-26 Martin Baulig <martin@gnome.org>
1889 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
1891 2002-04-25 Miguel de Icaza <miguel@ximian.com>
1893 * class.cs (Property): use the new typemanager.MemberLookup
1895 (TypeContainer.MemberLookup): Implement using the
1896 TypeManager.MemberLookup now.
1898 * typemanager.cs: Make MemberLookup a function of the TypeManager,
1899 and return MemberInfos, so that these can be used without an
1900 EmitContext (what we had before).
1902 2002-04-24 Miguel de Icaza <miguel@ximian.com>
1904 * expression.cs: Fix the case where the argument to params if the
1905 type of the params. I omitted handling this before. Fixed
1907 2002-04-22 Miguel de Icaza <miguel@ximian.com>
1909 * driver.cs: Call BootCorlib_PopulateCoreType
1911 * class.cs (Property.CheckBase): Check for properties only, not
1914 * interface.cs: Temporary hack: try/catch around the
1915 CustomAttributeBuilder, because I am getting an exception that I
1918 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
1919 types whose definitions are required to be there (attributes are
1920 defined before standard types).
1922 Compute definitions as we boot the various types, as they are used
1923 immediately (value_type class will need object_type, but if we do
1924 not initialize object_type, we will pass a null, which will let
1925 the runtime pick the System.Object from the existing corlib, which
1926 is not what we want).
1928 2002-04-22 Patrik Torstensson <totte@labs2.com>
1930 * cs-tokenizer.cs: fixed a number of trim() issues.
1932 2002-04-22 Ravi Pratap <ravi@ximian.com>
1934 * expression.cs (Argument.Type): Ensure that we return the correct
1935 type when we have out or ref parameters [in which case we
1938 2002-04-22 Miguel de Icaza <miguel@ximian.com>
1940 * class.cs (Property, Indexer): Allow extern modifier in there.
1942 * typemanager.cs (InitBaseTypes): Initializes object_type and
1943 value_type, since those will be used early on during the bootstrap
1944 process to compile corlib.
1946 (InitCoreTypes): Move code from here to InitBaseTypes.
1948 2002-04-21 Miguel de Icaza <miguel@ximian.com>
1950 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
1951 single-dimension arrays as using the ldlen opcode.
1953 Daniel Lewis discovered this optimization.
1955 * typemanager.cs: Add signature for System.Array::get_Length
1957 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1959 * statement.cs: report the error when the foreach does not apply to an
1960 array nor a collection.
1962 2002-04-19 Miguel de Icaza <miguel@ximian.com>
1964 * expression.cs: Add implicit conversions to the operator ~.
1966 * constant.cs (DecimalConstant.Emit): Emit decimal value.
1968 * typemanager.cs: Locate the decimal constructor.
1970 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1972 * attribute.cs: use the new property of TypeOf.
1973 * expression.cs: added 'get' property around typearg.
1975 These changes fix a build breaker reported by NickD. Is this the
1976 correct way to fix? If not, please, revert my changes and make it
1979 2002-04-17 Miguel de Icaza <miguel@ximian.com>
1981 * attribute.cs: Add support for typeof in attribute invocations.
1982 I am not sure that this is right though.
1984 2002-04-14 Duncan Mak <duncan@ximian.com>
1986 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
1987 Binary.Operator.Division case.
1989 2002-04-13 Ravi Pratap <ravi@ximian.com>
1991 * class.cs (DefineType): Ensure that we do a proper check on
1992 attribute types and also register it with the TypeManager.
1994 (TypeContainer.Targets): The default for attribute types is
1995 AttributeTargets.All.
1997 * attribute.cs (ApplyAttributes): Registering the attribute type
1998 is done elsewhere, not when we discover we have a Usage attribute.
2000 2002-04-12 Ravi Pratap <ravi@ximian.com>
2002 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
2003 and get rid of is_delegate parameter.
2005 * everywhere : update.
2007 2002-04-12 Ravi Pratap <ravi@ximian.com>
2009 * cs-parser.jay (compilation_unit): Revamp completely to use
2010 some new ideas that I got from Rhys' grammar to solve the problems
2011 with assembly level attributes.
2013 (outer_declaration): New grammar production.
2015 (attribute_sections): Add.
2017 (opt_attributes): Base on attribute_sections
2019 (namespace_declaration): Allow opt_attributes to tackle the case
2020 when we have assembly level attributes - we are clever in this
2023 * attribute.cs (ApplyAttributes): Do not worry about assembly
2024 attributes in the non-global context.
2026 * rootcontext.cs (AddGlobalAttributes): Go back to using this
2027 instead of SetGlobalAttributes.
2029 * class.cs, rootcontext.cs : Ensure we define and generate
2030 attribute types before anything else.
2032 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
2033 and flag the new error -20 for the case when the attribute type
2034 does not have valid targets specified. csc does not catch this.
2036 * ../errors/errors.txt : update for error # -20
2038 2002-04-11 Ravi Pratap <ravi@ximian.com>
2040 * support.cs (InternalParameters.ParameterModifier): Do some null
2041 checking and return sane values.
2043 * class.cs (Method.Define): If we are a PInvoke method, ensure
2044 that we are static and extern. Report error # 601
2046 * ../errors/cs0601.cs : Add test case for the above error.
2048 2002-04-07 Ravi Pratap <ravi@ximian.com>
2050 * rootcontext.cs (attribute_types): We need to keep type of
2051 all attribute types separately and emit code for them first.
2053 (RegisterAttribute) : Implement.
2055 * class.cs (DefineType): Check if the current Type is a custom
2056 attribute type and register it accordingly.
2058 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
2059 adding the first attribute twice and rename to
2061 (SetGlobalAttributes): this.
2063 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
2066 * attribute.cs (ApplyAttributes): Take an additional argument telling us
2067 if we are processing global arguments. Hmm, I am unsure of this.
2069 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2071 * expression.cs: added static array of strings to avoid calling
2072 Enum.ToString () for Operator in Binary. Significant recover of
2075 2002-04-10 Miguel de Icaza <miguel@ximian.com>
2077 * class.cs (FindMembers): Allow the Builders of the various
2078 members to be null. If they are skip them. This only happens
2079 during the PInvoke declaration.
2081 2002-04-09 Miguel de Icaza <miguel@ximian.com>
2083 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
2084 failure, so we do not keep going afterwards.
2086 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
2087 wanted to pass `false' as the `is_delegate' argument. If this is
2088 the case, why not use delegate_type == null to mean `is_delegate =
2089 false' and anything else as is_delegate = true.
2091 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
2093 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
2094 code for the section, not the beginning of the tests.
2096 2002-04-08 Miguel de Icaza <miguel@ximian.com>
2098 * cfold.cs: Handle operator + (Enum x, Underlying x)
2100 * expression.cs (Binary): same. Warn about errors where we have
2101 Enum/Enum in operator + as well.
2103 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
2106 - added support for switch(bool)
2107 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
2108 - add TableSwitchEmit() to handle table-based switch statements
2110 2002-04-05 Ravi Pratap <ravi@ximian.com>
2112 * expression.cs (Invocation.OverloadResolve): Factor out code which
2113 does parameter compatibility checking with arguments so that we can
2114 re-use the code even from Delegate.VerifyApplicability
2116 (VerifyArgumentsCompat): Move above code here.
2118 * delegate.cs (VerifyApplicability): Get rid of duplicate code
2119 and instead make a call to the above method.
2121 2002-03-31 Ravi Pratap <ravi@ximian.com>
2123 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
2124 We use it to keep track of classes which are attribute types.
2126 2002-04-02 Miguel de Icaza <miguel@ximian.com>
2128 * delegate.cs (Delegate.Define): Correctly define the types in the
2129 presence of fixed and array parameters.
2131 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
2134 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
2135 include NonPublic after the first iteration.
2137 * class.cs (Indexer.CheckBase): Only check if both parents are
2140 * cs-parser.jay (accessor_body): If empty, set to null.
2142 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
2143 same code path here to resolve constants names that we did have in
2144 MemberAccess.DoResolve. There is too much code duplicated here.
2146 2002-04-01 Miguel de Icaza <miguel@ximian.com>
2148 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
2150 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
2153 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
2154 tokens, numbers and strings.
2156 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
2159 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
2160 asyncronous parameters and the regular parameters.
2162 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
2163 specify the target directory.
2165 * expression.cs: (This.DoResolve): Simplify
2166 (As.Emit): Optimize, do not generate IsInst if the expression is
2167 always of the given type.
2169 (Is.DoResolve): Bug fix, we were reporting both always/never for
2172 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
2173 creating too many unnecessary arrays.
2175 2002-03-31 Miguel de Icaza <miguel@ximian.com>
2177 * class.cs (EmitFieldInitializer): Use Assign expression to assign
2178 fields instead of rolling our own initializer. Takes care of all
2179 implicit conversions, and drops unnecessary static checks/argument.
2181 2002-03-31 Dick Porter <dick@ximian.com>
2183 * driver.cs: use the GetDirectories() return values properly, and
2184 use "/" as path separator.
2186 2002-03-30 Miguel de Icaza <miguel@ximian.com>
2188 * expression.cs (Unary): Optimize - - expr into expr.
2189 (Binary): Optimize a + (-b) into a -b.
2191 * codegen.cs (CodeGen): Made all methods static.
2193 2002-03-29 Miguel de Icaza <miguel@ximian.com>
2197 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
2198 TypeBuilder property.
2200 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
2203 * tree.cs: Removed the various RecordXXXX, and replaced with a
2204 single RecordDecl. Removed all the accessor methods, and just
2205 left a single access point Type
2207 * enum.cs: Rename DefineEnum to DefineType.
2209 * decl.cs: New abstract method `DefineType' used to unify the
2210 Defines for Enumerations, Interfaces, TypeContainers and
2213 (FindType): Moved LookupInterfaceOrClass here. Moved the
2214 LookupBaseClasses method that used to live in class.cs and
2215 interface.cs here, and renamed to FindType.
2217 * delegate.cs: Implement DefineType. Take advantage of the
2218 refactored pattern for locating the parent builder without taking
2219 the parent_builder argument (which we know does not work if we are
2220 nested, and triggering a toplevel definition).
2222 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2224 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
2225 accessibility of a member has changed during override and report
2228 * class.cs (Method.Define, Property.Define): Only complain on
2229 overrides if the method is private, any other accessibility is
2230 fine (and since we just checked the permission is the same, we are
2233 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
2234 and elif are processed always. The other pre-processing
2235 directives are only processed if we are "taking" the path
2237 2002-03-29 Martin Baulig <martin@gnome.org>
2239 * class.cs (Method.Emit): Only emit symbolic debugging info if the
2240 current location is not Null.
2242 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
2243 a separate method so we can profile it.
2245 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
2246 `span.Seconds' are just seconds, but no minutes or hours.
2247 (MainDriver): Profile the CodeGen.SaveSymbols calls.
2249 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2251 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
2252 Remove the gratuitous set of Final:
2254 // If an interface implementation, then we can set Final.
2255 if (((flags & MethodAttributes.Abstract) == 0) &&
2256 implementing.DeclaringType.IsInterface)
2257 flags |= MethodAttributes.Final;
2259 I do not know what I was smoking when I used that.
2262 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
2263 step into fixing the name resolution issues for delegates and
2264 unifying the toplevel name resolution.
2266 2002-03-28 Martin Baulig <martin@gnome.org>
2268 * class.cs (Method.Emit): If we have a symbol writer, call its
2269 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
2270 tell it about the current method.
2272 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
2273 writer that we're going to emit the first byte of IL code for a new
2274 statement (a new source line).
2275 (EmitContext.EmitTopBlock): If we have a symbol writer, call
2276 EmitContext.Mark() before emitting any code.
2278 * location.cs (SymbolDocument): Return null when we're Null.
2280 * statement.cs (Statement): Moved the `Location loc' variable here.
2281 (Statement.EmitBoolExpression): If we have a symbol writer, call
2282 ec.Mark() before emitting any code to tell it that we're at the
2283 beginning of a new statement.
2284 (StatementExpression): Added `Location' argument to the constructor.
2285 (Block): Added public readonly variable `StartLocation' and public
2286 variable `EndLocation'. The latter is to be set using SetEndLocation().
2287 (Block): Added constructor which takes a start and end location.
2288 (Block.SetEndLocation): New method. This sets the end location.
2289 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
2290 local variables we create.
2291 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
2292 each statement and do also mark the begin and end of the block.
2294 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
2295 tell it the current lexer.Location, use Location.Null for the end of the
2297 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
2298 current block, set its end location using SetEndLocation().
2299 (statement_expression): StatementExpression constructor now takes the
2300 lexer.Location as additional argument.
2301 (for_statement, declare_local_variables): Likewise.
2302 (declare_local_variables): When creating a new implicit block, use the
2303 new Block constructor and pass it the lexer.Location.
2305 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2307 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
2308 members also on the parent interfaces recursively.
2310 2002-03-27 Miguel de Icaza <miguel@ximian.com>
2312 * report.cs: Use new formats, since Gonzalo finished the missing
2315 * expression.cs (Binary.ResolveOperator): added missing operator|
2316 operator& and operator^ for bool/bool.
2318 * cs-parser.jay: CheckDef now takes a Location argument that is
2319 used to report errors more precisly (instead of reporting the end
2320 of a definition, we try to track something which is a lot closer
2321 to the source of the problem).
2323 * cs-tokenizer.cs: Track global token use, so we can properly flag
2324 the use of #define/#undef after the first token has been seen.
2326 Also, rename the reportXXXX to Error_DescriptiveName
2328 * decl.cs (DeclSpace.IsTopLevel): Move property here from
2329 TypeContainer, so that Enum and Interface can use this too.
2331 * class.cs (TypeContainer.LookupInterfaceOrClass,
2332 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
2333 `builder' argument. Typically this was used to pass the parent
2334 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
2337 The problem is that a nested class could trigger the definition of
2338 a toplevel class, and the builder would be obviously wrong in that
2341 So we drop this argument, and we compute dynamically the
2342 TypeBuilder/ModuleBuilder (the correct information was available
2343 to us anyways from DeclSpace.Parent)
2345 * interface.cs (Interface.DefineInterface): Drop builder
2346 parameter cleanup like class.cs
2348 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
2351 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
2354 (Try.Emit): Propagate the returns value from the statement.
2356 (Return.Emit): Even if we are leavning
2358 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
2360 * modifiers.cs: Fix the computation of MethodAttributes flags.
2362 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
2364 * driver.cs: allow compilation of files that start with '/'.
2365 Add a default case when checking the argument of --target.
2367 2002-03-25 Miguel de Icaza <miguel@ximian.com>
2369 * interface.cs: Implement the same search algorithm for types in
2372 * delegate.cs: Do not allow multiple definition.
2374 * Recovered ChangeLog that got accidentally amputated
2376 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
2378 * rootcontext.cs: Load manually enum to allow core classes to
2379 contain enumerations.
2381 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
2382 Update to new static methods in TypeManager.
2384 * typemanager.cs (GetMethod, GetConstructor): Use our
2385 implementation of FindMembers to find the members, since during
2386 corlib compilation, the types are TypeBuilders and GetMethod and
2387 GetConstructor do not work.
2389 Make all methods in TypeManager static.
2391 (InitCodeHelpers): Split the functionality from
2392 the InitCodeTypes function.
2394 * driver.cs: Call InitCodeHelpers after we have populated the
2397 * cs-parser.jay (delegate_declaration): we did not used to compute
2398 the delegate name correctly for void delegates.
2400 2002-03-24 Miguel de Icaza <miguel@ximian.com>
2402 * rootcontext.cs (RootContext): Init the interface_resolve_order
2403 and type_container_resolve_order always.
2405 (ResolveCore, BootstrapCorlib_ResolveClass,
2406 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
2407 compiler when compiling with --nostdlib
2409 * class.cs (TypeContainer.DefineType): Check that our parent is
2410 not null. This test is most important when we are bootstraping
2413 * codegen.cs: Split out the symbol writing code.
2415 2002-03-25 Martin Baulig <martin@gnome.org>
2417 * driver.cs (-g): Made -g an alias for --debug.
2419 2002-03-24 Martin Baulig <martin@gnome.org>
2421 * codegen.cs (SymbolWriter): New public variable. Returns the
2422 current symbol writer.
2423 (CodeGen): Added `bool want_debugging_support' argument to the
2424 constructor. If true, tell the ModuleBuild that we want debugging
2425 support and ask it for the ISymbolWriter.
2426 (Save): If we have a symbol writer, call it's Close() method after
2427 saving the assembly.
2429 * driver.c (--debug): New command line argument to create a
2430 debugger information file.
2432 * location.cs (SymbolDocument): New public property. Returns an
2433 ISymbolDocumentWriter object for the current source file or null
2434 if we don't have a symbol writer.
2436 2002-03-21 Miguel de Icaza <miguel@ximian.com>
2438 * driver.cs (LoadAssembly): Correctly return when all the paths
2439 have been tried and not before.
2441 * statement.cs (Switch.Emit): return the actual coverage for this
2442 statement (returns/not-returns)
2444 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
2445 switch of the statement if we are the last switch section. That
2446 kills two problems: try/catch problems (we used to emit an empty
2447 nop at the end) and switch statements where all branches would
2450 2002-03-19 Miguel de Icaza <miguel@ximian.com>
2452 * driver.cs: Add default assemblies (the equivalent to the
2453 Microsoft CSC.RSP file)
2455 * cs-tokenizer.cs: When updating `cols and setting it to zero,
2456 also update tokens_seen and set it to false.
2458 * driver.cs: Implement --recurse for Mike.
2460 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
2461 correctly splitting out the paths.
2463 2002-03-18 Miguel de Icaza <miguel@ximian.com>
2465 * interface.cs (Interface.PopulateProperty): Instead of using
2466 `parent' as the declaration space for the set parameters, use
2469 * support.cs (InternalParameters): InternalParameters constructor
2470 takes a DeclSpace instead of a TypeContainer.
2472 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
2473 types are being initialized, load the address of it before calling
2476 (New): Provide a mechanism to disable the generation of local
2477 value type temporaries when the caller will be providing us with
2478 an address to store it.
2480 (ArrayCreation.EmitDynamicInitializers): Use it.
2482 2002-03-17 Miguel de Icaza <miguel@ximian.com>
2484 * expression.cs (Invocation.EmitArguments): Only probe for array
2485 property if there is more than one argument. Sorry about that.
2487 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
2490 * class.cs (Method.LabelParameters): Fix incorrect code path that
2491 prevented the `ParamArrayAttribute' from being applied to the
2494 2002-03-16 Miguel de Icaza <miguel@ximian.com>
2496 * support.cs (ReflectionParameters): Correctly compute whether the
2497 last argument is a params array. Fixes the problem with
2500 * typemanager.cs: Make the assemblies array always be non-null
2501 (empty, but non-null)
2503 * tree.cs (RecordDecl): New function that abstracts the recording
2504 of names. This reports error 101, and provides a pointer to the
2505 previous declaration. Fixes a crash in the compiler.
2507 * cs-parser.jay (constructor_declaration): Update to new grammar,
2508 and provide a constructor_body that can be empty.
2510 2002-03-15 Miguel de Icaza <miguel@ximian.com>
2512 * driver.cs: Add support for --resources.
2514 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
2515 Make all types for the various array helper methods be integer.
2517 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
2518 CheckState to ConvCast.
2520 (ConvCast): Now it takes a `checked' state argument, to avoid
2521 depending on the emit context for the conversion, and just using
2522 the resolve time setting.
2524 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
2525 instead of Invocation.EmitArguments. We do not emit the original
2526 arguments, instead we emit those which have been converted to
2527 unsigned int expressions.
2529 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
2531 * codegen.cs: ditto.
2533 * expression.cs (LocalVariableReference): Drop the use of the
2534 Store function that depended on the variable index.
2536 * statement.cs (VariableInfo): Drop the `Idx' property from this
2537 class, as this is not taking into account the indexes for
2538 temporaries tat we generate during the execution, getting the
2541 * class.cs: First emit class initializers, then call the parent
2544 * expression.cs (Binary): Fix opcode emision.
2545 (UnaryMutator.EmitCode): Support checked code generation
2547 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
2548 matches for events for both the Static and Instance scans,
2549 pointing to the same element. Fix that.
2551 2002-03-14 Miguel de Icaza <miguel@ximian.com>
2553 * rootcontext.cs (ResolveTree): Always set the
2554 interface_resolve_order, because nested interfaces will be calling
2557 * class.cs (GetInterfaceOrClass): Track the same resolution
2558 process used by TypeManager.LookupType. This fixes the nested
2559 type lookups in class declarations (separate path from
2562 (TypeContainer.DefineType): Also define nested interfaces.
2563 (TypeContainer.RegisterOrder): New public function used to
2564 register the order in which child interfaces need to be closed.
2566 Nested interfaces need to be closed after their parents have been
2569 * interface.cs (InterfaceAttr): Put all the logic for computing
2570 the interface attribute here.
2572 (DefineInterface): Register our interface order with the
2573 RootContext or with the TypeContainer depending on the case.
2575 2002-03-12 Miguel de Icaza <miguel@ximian.com>
2577 * cs-parser.jay: rework foreach statement to work with the new
2578 changes to the policy on SimpleNames.
2580 * report.cs: support Stacktrace on warnings as well.
2582 * makefile: drop --unsafe and /unsafe from the compile.
2584 2002-03-13 Ravi Pratap <ravi@ximian.com>
2586 * ecore.cs (StandardConversionExists): Modify to take an Expression
2587 as the first parameter. Ensure we do null -> reference type conversion
2590 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
2591 temporary Expression objects.
2593 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
2595 * interface.cs: workaround bug in method overloading resolution
2596 (there is already a bugzilla bug for it).
2598 2002-03-12 Miguel de Icaza <miguel@ximian.com>
2600 We could also solve this problem by having a separate path for
2601 performing type lookups, instead of DoResolve, we could have a
2602 ResolveType entry point, and only participating pieces of the
2603 production (simplename, deref, array) would implement this.
2605 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
2606 signal SimpleName to only resolve type names and not attempt to
2607 resolve anything else.
2609 * expression.cs (Cast): Set the flag.
2611 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
2613 * class.cs: Only report 108 if there is no `new' modifier.
2615 * cs-parser.jay: rework foreach statement to work with the new
2616 changes to the policy on SimpleNames.
2618 * report.cs: support Stacktrace on warnings as well.
2620 * makefile: drop --unsafe and /unsafe from the compile.
2622 2002-03-11 Miguel de Icaza <miguel@ximian.com>
2624 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
2625 lookups here, instead of doing that at parse time. This means
2626 that our grammar will not introduce `LocalVariableReferences' as
2627 expressions at this point. That solves the problem of code like
2635 This is only half the fix. The full fix requires parameters to
2636 also be handled in this way.
2638 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
2639 makes the use more obvious of the DeclSpace. The
2640 ec.TypeContainer.TypeBuilder is now only used to pull the
2643 My theory is that I can get rid of the TypeBuilder completely from
2644 the EmitContext, and have typecasts where it is used (from
2645 DeclSpace to where it matters).
2647 The only pending problem is that the code that implements Aliases
2648 is on TypeContainer, and probably should go in DeclSpace.
2650 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
2651 lookups here, instead of doing that at parse time. This means
2652 that our grammar will not introduce `LocalVariableReferences' as
2653 expressions at this point. That solves the problem of code like
2661 This is only half the fix. The full fix requires parameters to
2662 also be handled in this way.
2664 * class.cs (Property.DefineMethod): When implementing an interface
2665 method, set newslot, when implementing an abstract method, do not
2666 set the flag (before we tried never setting it, or always setting
2667 it, which is the difference).
2668 (Indexer.DefineMethod): same.
2669 (Method.DefineMethod): same.
2671 * ecore.cs: Only set the status used flag if we get back a Field.
2673 * attribute.cs: Temporary hack, so Paolo can keep working.
2675 2002-03-08 Ravi Pratap <ravi@ximian.com>
2677 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
2678 the unmanaged type in the case we have a MarshalAs attribute.
2680 (Resolve): Handle the case when we are parsing the special MarshalAs
2681 attribute [we need to store the unmanaged type to use later]
2683 * typemanager.cs (marshal_as_attr_type): Built in type for the
2684 MarshalAs Attribute.
2686 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
2687 on parameters and accordingly set the marshalling info.
2689 2002-03-09 Miguel de Icaza <miguel@ximian.com>
2691 * class.cs: Optimizing slightly by removing redundant code after
2692 we switched to the `NoTypes' return value.
2693 (Property.DefineMethod): use NoTypes here too.
2695 This fixes the bug I introduced in my last batch of changes.
2697 2002-03-05 Ravi Pratap <ravi@ximian.com>
2699 * tree.cs (RecordEnum): Add. We now keep track of enums too.
2701 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
2702 Enums since those are types too.
2704 * cs-parser.jay (enum_declaration): Record enums as we parse them.
2706 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
2707 thanks to a call during the lookup process.
2709 2002-03-07 Miguel de Icaza <miguel@ximian.com>
2711 * statement.cs (Foreach): Lots of work to accomodate a particular
2712 kind of foreach statement that I had not kept in mind. It is
2713 possible to have foreachs on classes that provide a GetEnumerator
2714 method that return objects that implement the "pattern" for using
2715 a foreach, there is no need to support GetEnumerator
2718 This is needed to compile nant.
2720 * decl.cs: Only report 114 if the member is not `Finalize' and if
2721 the warning level is at least 2.
2723 * class.cs: Moved the compare function from Method to
2726 (MethodSignature.InheritableMemberSignatureCompare): Add new
2727 filter function that is used to extract inheritable methods from a
2730 (Method.Define): Use the new `inheritable_method_signature_filter'
2733 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
2736 2002-03-06 Miguel de Icaza <miguel@ximian.com>
2738 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
2740 * cs-parser.jay: Add opt_semicolon to the interface declaration.
2742 * expression.cs: Pass location information to
2743 ConvertImplicitStandard.
2745 * class.cs: Added debugging code to track return values from
2748 2002-03-05 Miguel de Icaza <miguel@ximian.com>
2750 * expression.cs (Is.DoResolve): If either side of the `is' is an
2751 interface, do not flag the warning.
2753 * ecore.cs (ImplicitReferenceConversion): We need a separate test
2756 * report.cs: Allow for --fatal to be used with --probe.
2758 * typemanager.cs (NoTypes): Move the definition for the empty Type
2761 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
2763 (TypeContainer.DefineProxy): New function used to proxy to parent
2764 implementations when implementing interfaces.
2765 (TypeContainer.ParentImplements): used to lookup if our parent
2766 implements a public function that is required by an interface.
2767 (TypeContainer.VerifyPendingMethods): Hook this up.
2769 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
2770 `modules' and `assemblies' arraylists into arrays. We only grow
2771 these are the very early start up of the program, so this improves
2772 the speedof LookupType (nicely measured).
2774 * expression.cs (MakeByteBlob): Replaced unsafe code with
2775 BitConverter, as suggested by Paolo.
2777 * cfold.cs (ConstantFold.Binary): Special case: perform constant
2778 folding of string concatenation, but if either side is a string,
2779 and the other is not, then return null, and let the runtime use
2780 the concatenation on the string plus the object (using
2783 2002-03-04 Miguel de Icaza <miguel@ximian.com>
2785 Constant Folding has been implemented now.
2787 * expression.cs (Unary.Reduce): Do not throw an exception, catch
2788 the error instead on types that are not supported in one's
2791 * constant.cs (Constant and all children): New set of functions to
2792 perform implict and explicit conversions.
2794 * ecore.cs (EnumConstant): Implement the new functions to perform
2795 conversion by proxying to the child expression.
2797 * codegen.cs: (ConstantCheckState): Constant evaluation has its
2798 own separate setting that can not be turned off from the command
2799 line using --unchecked or --checked and is only controlled using
2800 the checked/unchecked statements and expressions. This setting is
2801 used by the constant folder to flag errors.
2803 * expression.cs (CheckedExpr, UncheckedExpr): Set the
2804 ConstantCheckState as well.
2806 During Resolve, they also have to flag the state, because the
2807 constant folder runs completely in the Resolve phase.
2809 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
2812 2002-03-01 Miguel de Icaza <miguel@ximian.com>
2814 * cfold.cs: New file, this file contains the constant folder.
2816 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
2817 argument to track whether we are using the resulting address to
2818 load or store a value and provide better error messages.
2820 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
2821 new AddressOf arguments.
2823 * statement.cs (Foreach.EmitCollectionForeach): Update
2825 * expression.cs (Argument.Emit): Call AddressOf with proper
2826 arguments to track usage.
2828 (New.DoEmit): Call AddressOf with new arguments.
2830 (Unary.Emit): Adjust AddressOf call.
2832 2002-03-01 Ravi Pratap <ravi@ximian.com>
2834 * cs-parser.jay (member_access): Change the case for pre-defined types
2835 to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
2838 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
2841 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
2842 essentially like methods and apply attributes like MethodImplOptions to them too.
2844 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
2847 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
2848 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
2851 * Update code everywhere accordingly.
2853 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
2855 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
2857 2002-02-28 Ravi Pratap <ravi@ximian.com>
2859 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
2860 try performing lookups against those instead of jumping straight into using
2861 the 'using' clauses.
2863 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
2865 (LookupType): Perform lookups in implicit parents too.
2867 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
2868 sequence as RootContext.LookupType.
2870 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
2871 the various cases of namespace lookups into this method.
2873 2002-03-01 Miguel de Icaza <miguel@ximian.com>
2875 * cs-parser.jay: Add support for [Attribute ()] (empty arguments
2876 in positional arguments)
2878 * class.cs (Operator): Update the AllowedModifiers to contain
2881 * cs-parser.jay: Update operator declaration to allow for the
2882 operator body to be empty.
2884 * cs-tokenizer.cs: Added '\u' unicode support in strings and hex
2887 2002-02-27 Miguel de Icaza <miguel@ximian.com>
2889 * class.cs (Method.Emit): Label parameters.
2891 * driver.cs: Return 1 or 0 as the program exit code.
2893 2002-02-26 Miguel de Icaza <miguel@ximian.com>
2895 * expression.cs: Special case the `null' object when trying to
2896 auto-compute the type, as anything can be explicitly converted to
2899 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
2900 spotting this Paolo.
2902 (Expression.ImplicitNumericConversion): Perform comparissions of
2903 the type using the underlying type in the case of an enumeration
2904 rather than using the enumeration type for the compare.
2906 Cope with the underlying == type case, which is not possible to
2909 (Expression.ConvertNumericExplicit): Perform comparissions of
2910 the type using the underlying type in the case of an enumeration
2911 rather than using the enumeration type for the compare.
2913 * driver.cs: If the user does not supply an extension, assume .exe
2915 * cs-parser.jay (if_statement): Rewrote so that we can track the
2916 location for the if statement.
2918 * expression.cs (Binary.ConstantFold): Only concat strings when
2919 the operation is "+", not everything ;-)
2921 * statement.cs (Statement.EmitBoolExpression): Take a location
2923 (If, While, Do): Track location.
2925 * expression.cs (Binary.ResolveOperator): In the object + string
2926 case, I was missing a call to ConvertImplicit
2928 2002-02-25 Ravi Pratap <ravi@ximian.com>
2930 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
2931 Location arguments. Ensure we use RootContext.LookupType to do our work
2932 and not try to do a direct Type.GetType and ModuleBuilder.GetType
2934 * interface.cs (PopulateMethod): Handle the type of the parameter being
2937 * expression.cs (Invocation.BetterFunction): Handle the case when we
2938 have a params method with no fixed arguments and a call is made with no
2941 2002-02-25 Miguel de Icaza <miguel@ximian.com>
2943 * cs-tokenizer.cs: Add support for the quote-escape-sequence in
2944 the verbatim-string-literal
2946 * support.cs (InternalParameters.ParameterModifier): handle null
2948 (InternalParameters.ParameterType): ditto.
2950 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
2951 duplicating the name of the variable parameter.
2952 (GetParameterByName): Fix bug where we were not looking up array
2953 paramters if they were the only present (thanks Paolo!).
2954 (GetParameterInfo): We only have an empty set of types if both
2955 fixed and array are set to null.
2956 (GetParameterInfo-idx): Handle FixedParameter == null
2958 * cs-parser.jay: Handle the case where there is no catch
2959 statements (missing null test).
2961 2002-02-22 Miguel de Icaza <miguel@ximian.com>
2963 * driver.cs (MainDriver): Be conservative on our command line
2966 Catch DirectoryNotFoundException when calling GetFiles.
2968 (SplitPathAndPattern): Used to split the input specification into
2969 a path and a pattern that we can feed to Directory.GetFiles.
2971 2002-02-21 Miguel de Icaza <miguel@ximian.com>
2973 * statement.cs (Fixed): Implement the last case of the Fixed
2974 statement (string handling).
2976 * expression.cs (StringPtr): New class used to return a char * to
2977 a string; Used by the Fixed statement.
2979 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
2981 * expression.cs (Binary.ResolveOperator): Remove redundant
2982 MemberLookup pn parent type.
2983 Optimize union call, we do not need a union if the types are the same.
2984 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
2987 Specialize the use of MemberLookup everywhere, instead of using
2988 the default settings.
2990 (StackAlloc): Implement stackalloc keyword.
2992 * cs-parser.jay: Add rule to parse stackalloc.
2994 * driver.cs: Handle /h, /help, /?
2996 * expression.cs (MakeByteBlob): Removed the hacks we had in place
2997 before we supported unsafe code.
2999 * makefile: add --unsafe to the self compilation of mcs.
3001 2002-02-20 Miguel de Icaza <miguel@ximian.com>
3003 * expression.cs (PointerArithmetic): New class that is used to
3004 perform pointer arithmetic.
3005 (Binary.Resolve): Handle pointer arithmetic
3006 Handle pointer comparission.
3007 (ArrayPtr): Utility expression class that is used to take the
3008 address of an array.
3010 (ElementAccess): Implement array access for pointers
3012 * statement.cs (Fixed): Implement fixed statement for arrays, we
3013 are missing one more case before we are done.
3015 * expression.cs (Indirection): Implement EmitAssign and set the
3016 ExprClass to Variable. This allows pointer dereferences to be
3017 treated as variables, and to have values assigned to them.
3019 * ecore.cs (Expression.StoreFromPtr): New utility function to
3020 store values dereferencing.
3022 2002-02-20 Ravi Pratap <ravi@ximian.com>
3024 * expression.cs (Binary.ResolveOperator): Ensure that we are
3025 not trying to operate on a void type - this fixes the reported
3028 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
3029 the parent implementation is sealed.
3031 * ../errors/cs0239.cs : Add.
3033 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
3035 * typemanager.cs (unverifiable_code_type): Corresponds to
3036 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
3037 which have unsafe code in them.
3039 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
3042 2002-02-19 Miguel de Icaza <miguel@ximian.com>
3044 * cs-tokenizer.cs: Add support for @"litreal strings"
3046 Make tokenizer accept pre-processor directives
3047 on any column (remove the old C-like limitation).
3049 * rootcontext.cs (EmitCode): Emit any global attributes.
3050 (AddGlobalAttributes): Used to keep track of assembly attributes.
3052 * attribute.cs (ApplyAttributes): Support AssemblyAttributes.
3054 * cs-parser.jay: Add support for global attributes.
3056 2002-02-17 Miguel de Icaza <miguel@ximian.com>
3058 * expression.cs (Indirection): New helper class. Unary will
3059 create Indirection classes to be able to implement the
3060 IMemoryLocation interface on it.
3062 2002-02-16 Miguel de Icaza <miguel@ximian.com>
3064 * cs-parser.jay (fixed_statement): reference the right statement.
3066 * statement.cs (Fixed.Emit): Finish implementing the fixed
3067 statement for the &x case.
3069 2002-02-14 Miguel de Icaza <miguel@ximian.com>
3071 * class.cs (Property.Define, Method.Define): Remove newslot when
3074 * modifiers.cs: My use of NewSlot when `Abstract' was set was
3075 wrong. NewSlot should only be used if the `new' keyword is present.
3077 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
3078 locating our system dir. Sorry about this.
3080 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3082 * driver.cs (GetSystemDir): Compute correctly the location of our
3083 system assemblies. I was using the compiler directory instead of
3084 the library directory.
3086 2002-02-13 Ravi Pratap <ravi@ximian.com>
3088 * expression.cs (BetterFunction): Put back in what Miguel commented out
3089 since it is the correct fix. The problem is elsewhere ;-)
3091 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
3092 parameters of the parms method are themselves compatible or not !
3094 (StandardConversionExists): Fix very dangerous bug where we were forgetting
3095 to check that a class implements an interface before saying that an implicit
3096 conversion was allowed. Use ImplementsInterface to do the checking.
3098 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3100 * class.cs (Method.Define): Track whether we are an explicit
3101 implementation or not. And only call DefineMethodOverride if we
3102 are an explicit implementation.
3104 (Property.DefineMethod): Ditto.
3106 2002-02-11 Ravi Pratap <ravi@ximian.com>
3108 * expression.cs (BetterFunction): Catch hideous bug which was
3109 preventing us from detecting ambiguous calls due to implicit casts i.e
3112 2002-01-29 Miguel de Icaza <miguel@ximian.com>
3114 * support.cs (Pair): Remove un-needed method. I figured why I was
3115 getting the error in cs-parser.jay, the variable in a foreach loop
3116 is readonly, and the compiler does not really treat this as a variable.
3118 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
3119 instead of EQUALS in grammar.
3121 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
3123 * expression.cs (Unary.DoResolve): Check whether the argument is
3126 2002-01-28 Miguel de Icaza <miguel@ximian.com>
3128 * support.cs: Api for Pair to set a value. Despite the fact that
3129 the variables are public the MS C# compiler refuses to compile
3130 code that accesses the field if the variable is part of a foreach
3133 * statement.cs (Fixed): Begin implementation of the fixed
3136 (Block.AddVariable): Return the VariableInfo on success and null
3137 on failure instead of true/false.
3139 * cs-parser.jay (foreach): Catch errors on variables already
3140 defined (we were ignoring this value before) and properly unwind
3143 (fixed_statement): grammar for the fixed statement.
3145 2002-01-25 Miguel de Icaza <miguel@ximian.com>
3147 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
3148 pointer types to be incretemented.
3150 (SizeOf): Implement.
3152 * cs-parser.jay (pointer_member_access): Implement
3153 expr->IDENTIFIER production.
3155 * expression.cs (IndexerAccess.DoResolve, ArrayAccess.DoResolve,
3156 MemberAccess.DoResolve, Invocation.DoResolve): Check for pointers
3159 (Unary): Implement indirection.
3161 * ecore.cs (Expression.UnsafeError): Reports error 214 (pointer
3162 use in non-unsafe context).
3164 (SimpleName.DoResolve): Check for pointers in field access on safe
3167 (Expression.LoadFromPtr): Factor the load-indirect code in this
3168 function. This was duplicated in UnboxCast and ParameterReference
3170 2002-01-24 Miguel de Icaza <miguel@ximian.com>
3172 * expression.cs (ComposedCast): report an error if a pointer cast
3173 is used in a safe region.
3175 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
3176 pointer type casts in unsafe context.
3178 * codegen.cs (EmitContext): Set up IsUnsafe.
3180 * cs-parser.jay (non_expression_type): Add productions for pointer
3183 * expression.cs (Invocation.EmitCall): Remove chunk of buggy
3184 code. We should not use force into static mode if the method is
3185 not virtual. Fixes bug in MIS
3187 * statement.cs (Do.Emit, While.Emit, For.Emit,
3188 Statement.EmitBoolExpression): Add support to Do and While to
3189 propagate infinite loop as `I do return' semantics.
3191 Improve the For case to also test for boolean constants.
3193 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
3194 to the list of attributes we can add.
3196 Remove `EmitContext' argument.
3198 * class.cs (Method.Define): Apply parameter attributes.
3199 (Constructor.Define): Apply parameter attributes.
3200 (MethodCore.LabelParameters): Move here the core of labeling
3203 * support.cs (ReflectionParameters.ParameterModifier,
3204 InternalParameters.ParameterModifier): Use IsByRef on the type and
3205 only return the OUT bit for these parameters instead of in/out/ref
3208 This is because I miss-understood things. The ParameterInfo.IsIn
3209 and IsOut represent whether the parameter has the [In] and [Out]
3212 2002-01-22 Miguel de Icaza <miguel@ximian.com>
3214 * ecore.cs (FieldExpr.Emit): Release temporaries.
3216 * assign.cs (LocalTemporary.Release): new function.
3218 * codegen.cs (EmitContext.GetTemporaryStorage,
3219 EmitContext.FreeTemporaryStorage): Rework the way we deal with
3220 temporary storage. Now we can "put back" localbuilders when we
3223 2002-01-21 Miguel de Icaza <miguel@ximian.com>
3225 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
3226 need to make a copy of the variable to generate verifiable code.
3228 2002-01-19 Miguel de Icaza <miguel@ximian.com>
3230 * driver.cs: Compute dynamically the system directory.
3232 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
3233 Slower, but more generally useful. Used by the abstract
3234 registering implementation.
3236 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
3237 the rules for the special rule on Type/instances. First check if
3238 we have the same name, and if so, try that special static path
3239 rather than the instance path.
3241 2002-01-18 Miguel de Icaza <miguel@ximian.com>
3243 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
3246 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
3247 Enum, ValueType, Delegate or Array for non-corlib compiles.
3249 * cs-tokenizer.cs: Catch long identifiers (645)
3251 * typemanager.cs (IndexerPropetyName): Ravi never tested this
3254 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
3255 fix, we were returning too early, so we were not registering
3256 pending methods from abstract classes.
3258 Do not register pending methods if the class is abstract.
3260 * expression.cs (Conditional.DoResolve): Report circular implicit
3261 conversions when we neecd to compute it for conditional
3264 (Is.DoResolve): If the expression is always of the provided type,
3265 flag warning 183. If the expression can not ever be of the
3266 provided type flag warning 184.
3268 * class.cs: Catch 169 as well.
3270 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
3273 2002-01-18 Nick Drochak <ndrochak@gol.com>
3275 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.
3277 2002-01-17 Miguel de Icaza <miguel@ximian.com>
3279 * interface.cs: (PopulateMethod): Check for pointers being defined
3280 only if the unsafe context is active.
3281 (PopulateProperty): ditto.
3282 (PopulateIndexer): ditto.
3284 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
3285 specified. If pointers are present, make sure that they are
3286 present in an unsafe context.
3287 (Constructor, Constructor.Define): ditto.
3288 (Field, Field.Define): ditto.
3289 (Property, Property.Define): ditto.
3290 (Event, Event.Define): ditto.
3292 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
3293 hashtable if there are classes or structs defined.
3295 * expression.cs (LocalVariableReference.DoResolve): Simplify this
3296 code, as the constant resolution moved.
3298 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
3299 the metadata, so we can flag error 133.
3301 * decl.cs (MemberCore.UnsafeOK): New function to test that a
3302 pointer is being declared in an unsafe context.
3304 2002-01-16 Miguel de Icaza <miguel@ximian.com>
3306 * modifiers.cs (Modifiers.Check): Require a Location argument.
3307 Report error 227 for Unsafe use.
3309 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
3311 * statement.cs (For.Emit): If the test is null, then report that
3312 we do `return', as we wont reach anything afterwards.
3314 (Switch.SwitchGoverningType): Track the expression that matched
3317 * driver.cs: Allow negative numbers as an error code to flag.
3319 * cs-parser.jay: Handle 1551.
3321 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
3323 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3325 * cs-parser.jay: Report 1518 (type declaration can only contain
3326 class, struct, interface, enum or delegate)
3328 (switch_label): Report 1523 (keywords `case' or `default' must
3331 (opt_switch_sections): Report 1522 (empty switch)
3333 * driver.cs: Report 1515 (response file specified multiple times)
3334 Report 1516 (Source file specified multiple times).
3336 * expression.cs (Argument.Resolve): Signal 1510
3338 (BaseAccess.Resolve, BaseIndexer.Resolve): Signal 1511 (base
3339 access not allowed in static code)
3341 2002-01-11 Ravi Pratap <ravi@ximian.com>
3343 * typemanager.cs (IsPointerType): Utility method which we are going
3346 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
3347 the object type, so we take care of that.
3349 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
3351 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
3352 added to non-params parameters :-)
3354 * typemanager.cs (CSharpName): Include 'void' type too.
3356 (void_ptr_type): Include in the set of core types.
3358 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
3361 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
3364 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
3365 completely forgotten about it.
3367 2002-01-10 Ravi Pratap <ravi@ximian.com>
3369 * cs-parser.jay (pointer_type): Add. This begins our implementation
3370 of parsing rules for unsafe code.
3372 (unsafe_statement): Implement.
3374 (embedded_statement): Modify to include the above.
3376 * statement.cs (Unsafe): Implement new class for unsafe blocks.
3378 * codegen.cs (EmitContext.InUnsafe): Add. This determines
3379 if the current context is an unsafe one.
3381 * cs-parser.jay (local_variable_pointer_type): Since local variable types
3382 are handled differently, we need separate rules for them.
3384 (local_variable_declaration): Update to use local_variable_pointer_type
3385 to allow variable declarations of unmanaged pointer types.
3387 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
3390 * ../errors/cs0214.cs : Add.
3392 2002-01-16 Nick Drochak <ndrochak@gol.com>
3394 * makefile: remove 'response' file when cleaning.
3396 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3398 * cs-parser.jay: Report 1524.
3400 2002-01-14 Miguel de Icaza <miguel@ximian.com>
3402 * typemanager.cs (RegisterMethod): drop checking if we have
3403 registered this from here
3405 2002-01-12 Miguel de Icaza <miguel@ximian.com>
3407 * class.cs (Method.EmitDestructor): Implement calling our base
3410 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
3413 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
3414 this routine and will wrap the call in a try/catch block. Deal
3417 2002-01-11 Miguel de Icaza <miguel@ximian.com>
3419 * ecore.cs (Expression.MemberLookup): instead of taking a
3420 parameter `same_type' that was used to tell whether we could
3421 access private members we compute our containing type from the
3424 (FieldExpr): Added partial support for volatile fields. This does
3425 not work for volatile fields exposed from assemblies, as I can not
3426 figure out how to extract the modreq from it.
3428 Updated all the source files to use this.
3430 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
3431 because it is referenced by MemberLookup very often.
3433 2002-01-09 Ravi Pratap <ravi@ximian.com>
3435 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
3436 TypeBuilder.GetCustomAttributes to retrieve what we need.
3438 Get rid of redundant default_member_attr_type as this is the same as
3439 default_member_type which already exists.
3441 * interface.cs, attribute.cs : Update accordingly.
3443 2002-01-08 Miguel de Icaza <miguel@ximian.com>
3445 * typemanager.cs: Enable IndexerPropertyName again. It does not
3446 work for TYpeBuilders though. Ravi, can you please fix this?
3448 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
3450 * expression.cs (Argument.Emit): Handle the case of ref objects
3451 being passed to ref functions;
3453 (ParameterReference.EmitLoad): Loads the content of the pointer
3454 without dereferencing.
3456 2002-01-07 Miguel de Icaza <miguel@ximian.com>
3458 * cs-tokenizer.cs: Implemented the pre-processing expressions.
3460 2002-01-08 Ravi Pratap <ravi@ximian.com>
3462 * class.cs (Indexer.DefineMethod): Incorporate the interface
3463 type in the name of the method if we are doing explicit interface
3466 * expression.cs (ConversionExists): Remove as it is completely obsolete.
3468 (BetterConversion): Fix extremely trivial bug where we were referring to
3469 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
3472 * ../errors/bug16.cs : Add although we have fixed it.
3474 2002-01-07 Miguel de Icaza <miguel@ximian.com>
3476 * expression.cs (BaseIndexer): Begin implementation.
3478 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
3480 * cs-parser.jay (indexer_declarator): Use qualified_identifier
3481 production directly to remove a shift/reduce, and implement
3482 explicit interface implementation.
3484 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
3485 after a floating point suffix.
3487 * expression.cs (DoNumericPromotions): Improved the conversion for
3488 uint/uint. If we have a constant, we avoid doing a typecast to a
3491 * class.cs (Indexer): Implement explicit interface implementation
3494 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
3496 * class.cs: make the default instance constructor public and hidebysig.
3498 2001-01-03 Ravi Pratap <ravi@ximian.com>
3500 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
3501 so we can call it from elsewhere.
3503 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
3504 we emit it internally if the class has a defined indexer; otherwise the user
3505 emits it by decorating the class definition with the DefaultMemberAttribute.
3507 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
3508 attribute is not used on a type which defines an indexer.
3510 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
3511 character when we skip whitespace.
3513 * ../errors/cs0646.cs : Add.
3515 2002-01-03 Miguel de Icaza <miguel@ximian.com>
3517 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
3520 * makefile: Add practical target `mcs3.exe' which builds the third
3521 generation compiler.
3523 * expression.cs (New): Fix structures constructor calling.
3525 * class.cs (Property, Method, Indexer): Emit Final flag on the
3526 method if we are an interface implementation and we are not
3529 * ecore.cs (PropertyExpr): New public field `IsBase', tells
3530 whether this property is referencing a `base' method.
3532 * expression.cs (Invocation.EmitCall): take an extra argument:
3533 is_base, this is used to determine whether the `call' or
3534 `callvirt' opcode should be used.
3537 * delegate.cs: update EmitCall.
3539 * class.cs (Method.Define): Set NewSlot for the cases where we are
3540 not implementing an interface method.
3542 (Property.Define): ditto.
3544 2002-01-02 Miguel de Icaza <miguel@ximian.com>
3546 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
3547 'r'. Allows mcs to parse itself fully.
3549 2002-01-02 Ravi Pratap <ravi@ximian.com>
3551 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
3552 of the number of initializers that require the InitializeArray method.
3554 (CheckIndices): Store the Expression in all cases - not the plain value. Also
3555 update the above field where necessary.
3557 (MakeByteBlob): Update accordingly.
3559 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
3562 (EmitDynamicInitializers): Update in accordance with the new optimization.
3564 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
3565 same OpCode applies.
3567 * cs-parser.jay : Fix some glaring errors I introduced.
3569 2002-01-01 Ravi Pratap <ravi@ximian.com>
3571 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
3572 so that we can check for name clashes there too.
3574 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
3575 for interface indexers.
3577 * interfaces.cs (Define): Emit the default member attribute.
3579 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
3580 variable was being referred to while setting the value ;-)
3582 2002-01-01 Miguel de Icaza <miguel@ximian.com>
3584 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
3585 byte-by-byte information when we know the data is zero.
3587 Make the block always a multiple of 4, because
3588 DefineInitializedData has a bug.
3590 * assign.cs: Fix, we should assign from the temporary, not from
3593 * expression.cs (MakeByteBlob): Fix my incorrect code.
3595 2001-12-31 Miguel de Icaza <miguel@ximian.com>
3597 * typemanager.cs (EnumToUnderlying): This function is used to get
3598 the underlying type from an enumeration, because it does not
3601 * constant.cs: Use the I4_S form for values between -128 and 127.
3603 * statement.cs (Block.LookupLabel): Looks up a label.
3604 (Block): Drop support for labeled blocks.
3606 (LabeledStatement): New kind of statement that represents a label
3609 (Goto): Finally implement this bad boy.
3611 * cs-parser.jay: Update to reflect new mechanism to implement
3614 2001-12-30 Miguel de Icaza <miguel@ximian.com>
3616 * codegen.cs (EmitContext.This): a codegen property that keeps the
3617 a single instance of this instead of creating many different this
3620 * delegate.cs (Delegate.DoResolve): Update to use the property;
3622 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
3624 * expression.cs (BaseAccess.DoResolve): Ditto.
3626 2001-12-29 Ravi Pratap <ravi@ximian.com>
3628 * typemanager.cs (methodimpl_attr_type): Add to hold the type
3629 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
3631 (InitCoreTypes): Update accordingly.
3633 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
3634 so we can quickly store the state.
3636 (ApplyAttributes): Set the correct implementation flags
3637 for InternalCall methods.
3639 2001-12-29 Miguel de Icaza <miguel@ximian.com>
3641 * expression.cs (EmitCall): if a method is not virtual, then do
3642 not use callvirt on it.
3644 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
3645 user defined stuff) requires the use of stobj, which takes an
3646 address on the stack instead of an array and an index. So emit
3647 the Ldelema operation for it.
3649 (EmitStoreOpcode): Use stobj for valuetypes.
3651 (UnaryMutator.EmitCode): Use the right 1 value depending on
3652 whether we are dealing with int64/uint64, float or doubles.
3654 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
3655 constructors that I implemented last night.
3657 (Constructor.IsDefault): Fix to work properly for static
3660 * cs-parser.jay (CheckDef): report method signature errors.
3661 Update error number 103 to be 132.
3663 * decl.cs: New AdditionResult enumeration value: MethodExists.
3664 Although we do this check for methods later on in the semantic
3665 analysis, catching repeated default constructors is so easy that
3666 we catch these here.
3668 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
3671 (ParameterReference.EmitAssign, Emit): handle
3674 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
3675 (ArrayAccess.EmitStoreOpcode): ditto.
3677 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
3679 * expression.cs (MakeByteBlob): Complete all the missing types
3680 (uint, short, ushort, byte, sbyte)
3682 * class.cs: Only init instance field initializers on instance
3685 Rename `constructors' to instance_constructors.
3687 (TypeContainer.AddConstructor): Only add constructors to the list
3688 if it is not static.
3690 Make sure that we handle default_static_constructor independently
3691 everywhere where we handle instance_constructors
3693 2001-12-28 Miguel de Icaza <miguel@ximian.com>
3695 * class.cs: Do not lookup or create a base initializer for a
3698 (ConstructorInitializer.Resolve): use the proper type to lookup
3701 * cs-parser.jay: Report error 1585 (modifiers between type and name).
3703 * enum.cs, interface.cs: Remove CloseType, this is taken care by
3706 * decl.cs: CloseType is now an virtual method, the default
3707 implementation just closes this type.
3709 2001-12-28 Ravi Pratap <ravi@ximian.com>
3711 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
3712 to PreserveSig by default. Also emit HideBySig on such methods.
3714 Basically, set the defaults to standard values.
3716 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
3717 argument, if candidate is better, it can't be worse than the best !
3719 (Invocation): Re-write bits to differentiate between methods being
3720 applicable in their expanded form and their normal form - for params
3723 Get rid of use_standard everywhere as only standard conversions are allowed
3724 in overload resolution.
3726 More spec conformance.
3728 2001-12-27 Miguel de Icaza <miguel@ximian.com>
3730 * driver.cs: Add --timestamp, to see where the compiler spends
3733 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
3734 `this' in static code.
3736 (SimpleName.DoResolve): Implement in terms of a helper function
3737 that allows static-references to be passed upstream to
3740 (Expression.ResolveWithSimpleName): Resolve specially simple
3741 names when called by MemberAccess to implement the special
3744 (Expression.ImplicitReferenceConversion): Handle conversions from
3745 Null to reference types before others, as Null's type is
3748 * expression.cs (Invocation.EmitCall): Handle the special case of
3749 calling methods declared on a reference type from a ValueType
3750 (Base classes System.Object and System.Enum)
3752 (MemberAccess.Resolve): Only perform lookups on Enumerations if
3753 the left hand side is a TypeExpr, not on every enumeration.
3755 (Binary.Resolve): If types are reference types, then do a cast to
3756 object on operators != and == of both arguments.
3758 * typemanager.cs (FindMembers): Extract instance and static
3759 members if requested.
3761 * interface.cs (PopulateProperty): Use void_type instead of null
3762 as the return type for the setter method.
3764 (PopulateIndexer): ditto.
3766 2001-12-27 Ravi Pratap <ravi@ximian.com>
3768 * support.cs (ReflectionParameters): Fix minor bug where we
3769 were examining the wrong parameter for the ParamArray attribute.
3771 Cope with requests for the type of the parameter at position
3772 greater than the params parameter's. We now return the element
3773 type of the params array as that makes more sense.
3775 * expression.cs (Invocation.IsParamsMethodApplicable): Update
3776 accordingly as we no longer have to extract the element type
3779 (Invocation.OverloadResolve): Update.
3781 2001-12-27 Miguel de Icaza <miguel@ximian.com>
3783 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
3784 against IEnumerator, test whether the return value is a descendant
3785 of the IEnumerator interface.
3787 * class.cs (Indexer.Define): Use an auxiliary method to implement
3788 the other bits of the method definition. Begin support for
3789 explicit interface implementation.
3791 (Property.DefineMethod): Use TypeManager.void_type instead of null
3792 for an empty return value.
3794 2001-12-26 Miguel de Icaza <miguel@ximian.com>
3796 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
3797 dealing with a FieldExpr which is composed of a FieldBuilder, in
3798 the code path we did extract the constant, but we should have
3799 obtained the underlying value to be able to cast it (otherwise we
3800 end up in an infinite loop, this is what Ravi was running into).
3802 (ArrayCreation.UpdateIndices): Arrays might be empty.
3804 (MemberAccess.ResolveMemberAccess): Add support for section
3805 14.5.4.1 that deals with the special case of E.I when E is a type
3806 and something else, that I can be a reference to a static member.
3808 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
3809 handle a particular array type to create byte blobs, it is just
3810 something we dont generate byteblobs for.
3812 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
3815 * location.cs (Push): remove the key from the hashtable that we
3816 are about to add. This happens for empty files.
3818 * driver.cs: Dispose files after we have parsed them.
3820 (tokenize): new function that only runs the tokenizer on its
3821 input, for speed testing.
3823 2001-12-26 Ravi Pratap <ravi@ximian.com>
3825 * class.cs (Event.Define): Define the private field only if there
3826 are no accessors defined.
3828 * expression.cs (ResolveMemberAccess): If there is no associated
3829 field with the event, that means we have an event defined with its
3830 own accessors and we should flag error cs0070 since transforming
3831 ourselves into a field is not valid in that case.
3833 * ecore.cs (SimpleName.DoResolve): Same as above.
3835 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
3836 and charset to sane values.
3838 2001-12-25 Ravi Pratap <ravi@ximian.com>
3840 * assign.cs (DoResolve): Perform check on events only if they
3841 are being accessed outside the declaring type.
3843 * cs-parser.jay (event_declarations): Update rules to correctly
3844 set the type of the implicit parameter etc.
3846 (add_accessor, remove_accessor): Set current local parameters.
3848 * expression.cs (Binary): For delegate addition and subtraction,
3849 cast the return value from the method into the appropriate delegate
3852 2001-12-24 Ravi Pratap <ravi@ximian.com>
3854 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
3855 of these as the workaround is unnecessary.
3857 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
3858 delegate data - none of that is needed at all.
3860 Re-write bits to extract the instance expression and the delegate method
3863 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
3866 * attribute.cs (ApplyAttributes): New method to take care of common tasks
3867 of attaching attributes instead of duplicating code everywhere.
3869 * everywhere : Update code to do attribute emission using the above method.
3871 2001-12-23 Miguel de Icaza <miguel@ximian.com>
3873 * expression.cs (IsParamsMethodApplicable): if there are not
3874 parameters, return immediately.
3876 * ecore.cs: The 0 literal can be implicity converted to an enum
3879 (SimpleName.DoResolve): First lookup the type, then lookup the
3882 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
3883 want to get its address. If the InstanceExpression is not
3884 addressable, store the result in a temporary variable, then get
3887 * codegen.cs: Only display 219 errors on warning level or above.
3889 * expression.cs (ArrayAccess): Make it implement the
3890 IMemoryLocation interface.
3892 (Binary.DoResolve): handle the operator == (object a, object b)
3893 and operator != (object a, object b) without incurring into a
3894 BoxedCast (because 5 != o should never be performed).
3896 Handle binary enumerator operators.
3898 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
3899 value type, otherwise use Ldelem_ref.
3901 Use precomputed names;
3903 (AddressOf): Implement address of
3905 * cs-parser.jay (labeled_statement): Fix recursive block
3906 addition by reworking the production.
3908 * expression.cs (New.DoEmit): New has a special case:
3910 If we are dealing with a ValueType, we have a few
3911 situations to deal with:
3913 * The target of New is a ValueType variable, that is
3914 easy, we just pass this as the variable reference
3916 * The target of New is being passed as an argument,
3917 to a boxing operation or a function that takes a
3920 In this case, we need to create a temporary variable
3921 that is the argument of New.
3924 2001-12-23 Ravi Pratap <ravi@ximian.com>
3926 * rootcontext.cs (LookupType): Check that current_type is not null before
3927 going about looking at nested types.
3929 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
3930 not implement the IAssignMethod interface any more.
3932 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
3933 where we tranform them into FieldExprs if they are being resolved from within
3936 * ecore.cs (SimpleName.DoResolve): Do the same here.
3938 * assign.cs (DoResolve, Emit): Clean up code considerably.
3940 * ../errors/bug10.cs : Add.
3942 * ../errors/cs0070.cs : Add.
3944 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
3946 * assign.cs : Get rid of EventIsLocal everywhere.
3948 2001-12-23 Miguel de Icaza <miguel@ximian.com>
3950 * ecore.cs (ConvertIntLiteral): finished the implementation.
3952 * statement.cs (SwitchLabel): Convert the value we are using as a
3953 key before looking up the table.
3955 2001-12-22 Miguel de Icaza <miguel@ximian.com>
3957 * codegen.cs (EmitTopBlock): Require a Location argument now.
3959 * cs-parser.jay (constructor_declarator): We need to setup
3960 current_local_parameters before we parse the
3961 opt_constructor_initializer, to allow the variables to be bound
3962 to the constructor arguments.
3964 * rootcontext.cs (LookupType): First lookup nested classes in our
3965 class and our parents before we go looking outside our class.
3967 * expression.cs (ConstantFold): Extract/debox the values at the
3970 * rootcontext.cs (EmitCode): Resolve the constants first before we
3971 resolve the types. This is not really needed, but it helps debugging.
3973 * statement.cs: report location.
3975 * cs-parser.jay: pass location to throw statement.
3977 * driver.cs: Small bug fix.
3979 * report.cs: Updated format to be 4-zero filled digits.
3981 2001-12-22 Ravi Pratap <ravi@ximian.com>
3983 * expression.cs (CheckIndices): Fix minor bug where the wrong
3984 variable was being referred to ;-)
3986 (DoEmit): Do not call EmitStaticInitializers when the
3987 underlying type is System.Object.
3989 2001-12-21 Ravi Pratap <ravi@ximian.com>
3991 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
3992 and do the usual workaround for SRE.
3994 * class.cs (MyEventBuilder.EventType): New member to get at the type
3995 of the event, quickly.
3997 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
3999 * assign.cs (Assign.DoResolve): Handle the case when the target
4000 is an EventExpr and perform the necessary checks.
4002 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
4005 (SimpleName.MemberStaticCheck): Include check for EventExpr.
4007 (EventExpr): Set the type in the constructor itself since we
4008 are meant to be born fully resolved.
4010 (EventExpr.Define): Revert code I wrote earlier.
4012 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
4013 instance expression is null. The instance expression is a This in that case
4014 or a null, depending on whether it is a static method or not.
4016 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
4017 refers to more than one method.
4019 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
4020 and accordingly flag errors.
4022 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4024 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
4026 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4028 * location.cs (ToString): Provide useful rutine.
4030 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4032 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
4033 objects, return the actual integral boxed.
4035 * statement.cs (SwitchLabel): define an ILLabel for each
4038 (Switch.CheckSwitch): If the value is a Literal, extract
4039 the underlying literal.
4041 Also in the unused hashtable we had, add the SwitchLabel so we can
4042 quickly look this value up.
4044 * constant.cs: Implement a bunch of new constants. Rewrite
4045 Literal based on this. Made changes everywhere to adapt to this.
4047 * expression.cs (Expression.MakeByteBlob): Optimize routine by
4048 dereferencing array only once, and also copes with enumrations.
4050 bytes are two bytes wide, not one.
4052 (Cast): Perform constant conversions.
4054 * ecore.cs (TryImplicitIntConversion): Return literals instead of
4055 wrappers to the literals here.
4057 * expression.cs (DoNumericPromotions): long literals can converted
4058 to ulong implicity (this is taken care of elsewhere, but I was
4061 * ecore.cs (Expression.Literalize): Make the return type Literal,
4062 to improve type checking.
4064 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
4066 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4068 * literal.cs: Revert code from ravi that checked the bounds. The
4069 bounds are sane by the definition of the type itself.
4071 * typemanager.cs: Fix implementation of ImplementsInterface. We
4072 need to actually look up in our parent hierarchy for interfaces
4075 * const.cs: Use the underlying type for enumerations
4077 * delegate.cs: Compute the basename for the delegate creation,
4078 that should fix the delegate test case, and restore the correct
4079 Type Lookup semantics in rootcontext
4081 * rootcontext.cs: Revert Ravi's last patch. The correct way of
4082 referencing a nested type with the Reflection API is using the "+"
4085 * cs-parser.jay: Do not require EOF token at the end.
4087 2001-12-20 Ravi Pratap <ravi@ximian.com>
4089 * rootcontext.cs (LookupType): Concatenate type names with
4090 a '.' instead of a '+' The test suite passes again.
4092 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
4093 field of the enumeration.
4095 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
4096 the case when the member is an EventExpr.
4098 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
4099 static has an associated instance expression.
4101 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
4103 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
4105 * class.cs (Event.Define): Register event and perform appropriate checks
4108 We define the Add and Remove methods even if the use provides none because
4109 in that case, we provide default implementations ourselves.
4111 Define a private field of the type of the event. This is done by the CSC compiler
4112 and we should be doing it too ;-)
4114 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
4115 More methods we use in code we generate.
4117 (multicast_delegate_type, delegate_type): Two separate types since the distinction
4120 (InitCoreTypes): Update accordingly for the above.
4122 * class.cs (Event.Emit): Generate code for default accessors that we provide
4124 (EmitDefaultMethod): Do the job in the above.
4126 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
4129 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4131 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
4132 builders even if we were missing one.
4134 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
4135 pass the Basename as our class name instead of the Name. The
4136 basename will be correctly composed for us.
4138 * parameter.cs (Paramters): Now takes a Location argument.
4140 * decl.cs (DeclSpace.LookupType): Removed convenience function and
4141 make all the code call directly LookupType in RootContext and take
4142 this chance to pass the Location information everywhere.
4144 * Everywhere: pass Location information.
4146 2001-12-19 Miguel de Icaza <miguel@ximian.com>
4148 * class.cs (Constructor.Define): Updated way of detecting the
4149 length of the parameters.
4151 (TypeContainer.DefineType): Use basename as the type name for
4154 (TypeContainer.Define): Do not recursively define types here, as
4155 definition is taken care in order by the RootContext.
4157 * tree.cs: Keep track of namespaces in a per-file basis.
4159 * parameter.cs (Parameter.ComputeSignature): Update to use
4162 (Parameters.GetSignature): ditto.
4164 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
4165 instead of a TypeContainer.
4167 (Interface.SemanticAnalysis): Use `this' instead of our parent to
4168 resolve names. Because we need to be resolve in our context, not
4171 * driver.cs: Implement response files.
4173 * class.cs (TypeContainer.DefineType): If we are defined, do not
4176 (Event.Emit): Emit the code for add/remove handlers.
4177 (Event.Define): Save the MethodBuilders for add/remove.
4179 * typemanager.cs: Use pair here too.
4181 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
4182 DictionaryEntry requires the first argument to be non-null.
4184 (enum_declaration): Compute full name for registering the
4187 (delegate_declaration): Instead of using
4188 formal_parameter_list, use opt_formal_parameter_list as the list
4191 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
4192 (EventParsing): New property that controls whether `add' and
4193 `remove' are returned as tokens or identifiers (for events);
4195 2001-12-19 Ravi Pratap <ravi@ximian.com>
4197 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
4198 use MyEventBuilder only and let it wrap the real builder for us.
4200 (MyEventBuilder): Revamp constructor etc.
4202 Implement all operations that we perform on EventBuilder in precisely the same
4205 (FindMembers): Update to use the EventBuilder member.
4207 (Event.Emit): Update accordingly.
4209 2001-12-18 Ravi Pratap <ravi@ximian.com>
4211 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
4212 by calling the appropriate methods.
4214 (GetCustomAttributes): Make stubs as they cannot possibly do anything
4217 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
4219 2001-12-17 Ravi Pratap <ravi@ximian.com>
4221 * delegate.cs (Delegate.Populate): Check that the return type
4222 and various parameters types are indeed accessible.
4224 * class.cs (Constructor.Define): Same here.
4226 (Field.Define): Ditto.
4228 (Event.Define): Ditto.
4230 (Operator.Define): Check that the underlying Method defined itself
4231 correctly - so it's MethodBuilder should not be null.
4233 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
4234 expression happens to be null.
4236 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
4237 members but as of now we don't seem to be able to do anything really useful with it.
4239 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
4240 not the EventBuilder.
4242 2001-12-18 Miguel de Icaza <miguel@ximian.com>
4244 * cs-tokenizer.cs: Add support for defines.
4245 Add support for #if, #elif, #else, #endif
4247 (eval_var): evaluates a variable.
4248 (eval): stubbed for evaluating functions.
4250 * cs-parser.jay: Pass the defines information
4252 * driver.cs: Add --define command line option.
4254 * decl.cs: Move MemberCore here.
4256 Make it the base class for DeclSpace. This allows us to catch and
4257 report 108 and 109 for everything now.
4259 * class.cs (TypeContainer.Define): Extract all the members
4260 before populating and emit the warning 108 (new keyword required
4261 to override) instead of having each member implement this.
4263 (MemberCore.Define): New abstract method, we will be using this in
4264 the warning reporting engine in Populate.
4266 (Operator.Define): Adjust to new MemberCore protocol.
4268 * const.cs (Const): This does not derive from Expression, it is a
4269 temporary object we use to create fields, it is a MemberCore.
4271 * class.cs (Method.Define): Allow the entry point to be in a
4274 * driver.cs: Rewrite the argument handler to clean it up a bit.
4276 * rootcontext.cs: Made it just an auxiliary namespace feature by
4277 making everything static.
4279 * driver.cs: Adapt code to use RootContext type name instead of
4282 * delegate.cs: Remove RootContext argument.
4284 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
4287 * class.cs (Event.Define): The lookup can fail.
4289 * cs-tokenizer.cs: Begin implementation of pre-procesor.
4291 * expression.cs: Resolve the this instance before invoking the code.
4293 2001-12-17 Miguel de Icaza <miguel@ximian.com>
4295 * cs-parser.jay: Add a production in element_access that allows
4296 the thing to become a "type" reference. This way we can parse
4297 things like "(string [])" as a type.
4299 Note that this still does not handle the more complex rules of
4303 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
4305 * ecore.cs: (CopyNewMethods): new utility function used to
4306 assemble the list of methods from running FindMembers.
4308 (MemberLookup): Rework FindMembers so that
4310 2001-12-16 Miguel de Icaza <miguel@ximian.com>
4312 * class.cs (TypeContainer): Remove Delegates who fail to be
4315 * delegate.cs (Populate): Verify that we dont get null return
4316 values. TODO: Check for AsAccessible.
4318 * cs-parser.jay: Use basename to emit error 574 (destructor should
4319 have the same name as container class), not the full name.
4321 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
4322 possible representation.
4324 Also implements integer type suffixes U and L.
4326 2001-12-15 Miguel de Icaza <miguel@ximian.com>
4328 * expression.cs (ArrayCreation.DoResolve): We need to do the
4329 argument resolution *always*.
4331 * decl.cs: Make this hold the namespace. Hold the root context as
4333 (LookupType): Move here.
4335 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
4337 * location.cs (Row, Name): Fixed the code, it was always returning
4338 references to the first file.
4340 * interface.cs: Register properties defined through interfaces.
4342 * driver.cs: Add support for globbing on the command line
4344 * class.cs (Field): Make it derive from MemberCore as well.
4347 2001-12-15 Ravi Pratap <ravi@ximian.com>
4349 * class.cs (Event::Define): Check that the type of the event is a delegate
4350 type else flag error #66.
4352 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
4355 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
4356 values of EntryPoint, CharSet etc etc.
4358 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
4360 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
4361 be null and we should ignore this. I am not sure if this is really clean. Apparently,
4362 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
4363 which needs this to do its work.
4365 * ../errors/cs0066.cs : Add.
4367 2001-12-14 Miguel de Icaza <miguel@ximian.com>
4369 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
4372 * class.cs: (MethodSignature.MethodSignature): Removed hack that
4373 clears out the parameters field.
4374 (MemberSignatureCompare): Cleanup
4376 (MemberCore): New base class used to share code between MethodCore
4379 (RegisterRequiredImplementations) BindingFlags.Public requires
4380 either BindingFlags.Instace or Static. Use instance here.
4382 (Property): Refactored code to cope better with the full spec.
4384 * parameter.cs (GetParameterInfo): Return an empty array instead
4387 * class.cs (Property): Abstract or extern properties have no bodies.
4389 * parameter.cs (GetParameterInfo): return a zero-sized array.
4391 * class.cs (TypeContainer.MethodModifiersValid): Move all the
4392 method modifier validation to the typecontainer so we can reuse
4395 (MethodCore.ParameterTypes): return an empty sized array of types.
4397 (Property.Define): Test property modifier validity.
4399 Add tests for sealed/override too.
4401 (Method.Emit): abstract or extern methods have no bodies.
4403 2001-12-14 Ravi Pratap <ravi@ximian.com>
4405 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
4408 (Method::Define, ::Emit): Modify accordingly.
4410 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
4412 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
4414 * makefile: Pass in /unsafe.
4416 2001-12-13 Miguel de Icaza <miguel@ximian.com>
4418 * class.cs (MakeKey): Kill routine.
4420 * class.cs (TypeContainer.Define): Correctly define explicit
4421 method implementations (they require the full interface name plus
4424 * typemanager.cs: Deply the PtrHashtable here and stop using the
4425 lame keys. Things work so much better.
4427 This of course broke everyone who depended on `RegisterMethod' to
4428 do the `test for existance' test. This has to be done elsewhere.
4430 * support.cs (PtrHashtable): A hashtable that avoid comparing with
4431 the object stupid Equals method (because, that like fails all over
4432 the place). We still do not use it.
4434 * class.cs (TypeContainer.SetRequiredInterface,
4435 TypeContainer.RequireMethods): Killed these two routines and moved
4436 all the functionality to RegisterRequiredImplementations.
4438 (TypeContainer.RegisterRequiredImplementations): This routine now
4439 registers all the implementations required in an array for the
4440 interfaces and abstract methods. We use an array of structures
4441 which can be computed ahead of time to reduce memory usage and we
4442 also assume that lookups are cheap as most classes will not
4443 implement too many interfaces.
4445 We also avoid creating too many MethodSignatures.
4447 (TypeContainer.IsInterfaceMethod): Update and optionally does not
4448 clear the "pending" bit if we find that there are problems with
4451 (TypeContainer.VerifyPendingMethods): Update to report errors of
4452 methods that look like implementations but are not.
4454 (TypeContainer.Define): Add support for explicit interface method
4457 2001-12-12 Miguel de Icaza <miguel@ximian.com>
4459 * typemanager.cs: Keep track of the parameters here instead of
4460 being a feature of the TypeContainer.
4462 * class.cs: Drop the registration of parameters here, as
4463 InterfaceMethods are also interface declarations.
4465 * delegate.cs: Register methods with the TypeManager not only with
4466 the TypeContainer. This code was buggy.
4468 * interface.cs: Full registation here.
4470 2001-12-11 Miguel de Icaza <miguel@ximian.com>
4472 * expression.cs: Remove reducer for binary expressions, it can not
4475 * const.cs: Put here the code that used to go into constant.cs
4477 * constant.cs: Put here the code for constants, this is a new base
4480 * literal.cs: Make Literal derive from Constant.
4482 2001-12-09 Miguel de Icaza <miguel@ximian.com>
4484 * statement.cs (Return.Emit): Report error 157 if the user
4485 attempts to return from a finally block.
4487 (Return.Emit): Instead of emitting a return, jump to the end of
4490 * codegen.cs (EmitContext): ReturnValue, ReturnLabel: new
4491 LocalBuilder to store the result of the function. ReturnLabel is
4492 the target where we jump.
4495 2001-12-09 Radek Doulik <rodo@ximian.com>
4497 * cs-parser.jay: remember alias in current namespace

4575 2001-12-04 Miguel de Icaza <miguel@ximian.com>
4577 * statement.cs: The correct type for the EmptyExpression is the
4578 element_type, not the variable type. Ravi pointed this out.
4580 2001-12-04 Ravi Pratap <ravi@ximian.com>
4582 * class.cs (Method::Define): Handle PInvoke methods specially
4583 by using DefinePInvokeMethod instead of the usual one.

4842 (Cast.Cast): Take an expression as the target type.
4844 * cs-parser.jay (cast_expression): Remove old hack that only
4845 allowed a limited set of types to be handled. Now we take a
4846 unary_expression and we resolve to a type during semantic
4849 Use the grammar productions from Rhys to handle casts (this is
4850 not complete like Rhys syntax yet, we fail to handle that corner
4851 case that C# has regarding (-x), but we will get there.
4853 2001-11-22 Ravi Pratap <ravi@ximian.com>

4870 (MemberAccess::DoResolve): Fix the code which handles Enum literals to set
4871 the correct type etc.
4873 (ConvertExplicit): Handle Enum types by examining the underlying type.

4888 BindingFlags.Instance as well
4890 * ecore.cs (Expression.TryImplicitIntConversion): Wrap the result

4895 (Expression.ConvertExplicit): Add explicit type conversions done
4898 (Expression.ImplicitNumericConversion): Oops, forgot to test for

4902 2001-11-21 Miguel de Icaza <miguel@ximian.com>
4904 * cs-parser.jay (for_statement): Reworked the way For works: now
4905 we declare manually any variables that are introduced in
4906 for_initializer to solve the problem of having out-of-band code
4907 emition (that is what got for broken).
4909 (declaration_statement): Perform the actual variable declaration
4910 that used to be done in local_variable_declaration here.
4912 (local_variable_declaration): Do not declare anything, just pass

4980 we can use this elsewhere.
4982 * statement.cs: Finish implementation of foreach for single
4985 * cs-parser.jay: Use an out-of-band stack to pass information
4986 around, I wonder why I need this.

4990 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
4991 function used to return a static Parameters structure. Used for
4992 empty parameters, as those are created very frequently.

4996 2001-11-15 Ravi Pratap <ravi@ximian.com>
4998 * interface.cs : Default modifier is private, not public. The

5037 2001-11-09 Miguel de Icaza <miguel@ximian.com>

5060 * class.cs (Method.Emit): Clean up.
5062 * expression.cs (Argument.Resolve): Take another argument: the
5063 location where this argument is used. Notice that this is not
5064 part of the "Argument" class as to reduce the size of the
5065 structure (we know the approximate location anyways).
5067 Test if the argument is a variable-reference, if not, then
5068 complain with a 206.
5070 (Argument.Emit): Emit addresses of variables.
5072 (Argument.FullDesc): Simplify.
5074 (Invocation.DoResolve): Update for Argument.Resolve.

5101 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
5102 enumerations that are used in heavily used structures derive from

5105 home without adult supervision.
5107 * expression.cs (UnaryMutator): New class, used to handle ++ and
5108 -- separatedly from the other unary operators. Cleans up the
5109 code, and kills the ExpressionStatement dependency in Unary.
5111 (Unary): Removed `method' and `Arguments' from this class, making
5112 it smaller, and moving it all to SimpleCall, so I can reuse this
5113 code in other locations and avoid creating a lot of transient data
5114 strucutres when not required.
5116 * cs-parser.jay: Adjust for new changes.

5181 * class.cs, rootcontext.cs : Update accordingly.
5183 * typemanager.cs (RegisterField, GetValue): Workarounds for the fact that
5184 FieldInfo.GetValue does not work on dynamic types ! S.R.E lameness strikes again !
5186 * enum.cs (Populate): Register fields with TypeManager.RegisterField.
5188 * expression.cs (MemberAccess.DoResolve): Adjust code to obtain the value
5189 of a fieldinfo using the above, when dealing with a FieldBuilder.

5914 2001-10-14 Miguel de Icaza <miguel@ximian.com>
5916 * expression.cs: LocalTemporary: a new expression used to
5917 reference a temporary that has been created.
5919 * assign.cs: Handle PropertyAccess back here, so that we can
5920 provide the proper semantic access to properties.
5922 * expression.cs (Expression::ConvertReferenceExplicit): Implement
5923 a few more explicit conversions.
5925 * modifiers.cs: `NEW' modifier maps to HideBySig.
5927 * expression.cs (PropertyExpr): Make this into an
5928 ExpressionStatement, and support the EmitStatement code path.
5930 Perform get/set error checking, clean up the interface.
5932 * assign.cs: recognize PropertyExprs as targets, and if so, turn
5933 them into toplevel access objects.
5935 2001-10-12 Miguel de Icaza <miguel@ximian.com>
5937 * expression.cs: PropertyExpr::PropertyExpr: use work around the
5940 * typemanager.cs: Keep track here of our PropertyBuilders again to
5941 work around lameness in SRE.
5943 2001-10-11 Miguel de Icaza <miguel@ximian.com>
5945 * expression.cs (LValue::LValueResolve): New method in the
5946 interface, used to perform a second resolution pass for LValues.
5948 (This::DoResolve): Catch the use of this in static methods.
5950 (This::LValueResolve): Implement.
5952 (This::Store): Remove warning, assigning to `this' in structures
5955 (Invocation::Emit): Deal with invocation of
5956 methods on value types. We need to pass the address to structure
5957 methods rather than the object itself. (The equivalent code to
5958 emit "this" for structures leaves the entire structure on the
5959 stack instead of a pointer to it).
5961 (ParameterReference::DoResolve): Compute the real index for the
5962 argument based on whether the method takes or not a `this' pointer
5963 (ie, the method is static).
5965 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store
5966 value types returned from functions when we need to invoke a
5967 method on the sturcture.
5970 2001-10-11 Ravi Pratap <ravi@ximian.com>
5972 * class.cs (TypeContainer::DefineType): Method to actually do the business of
5973 defining the type in the Modulebuilder or Typebuilder. This is to take
5974 care of nested types which need to be defined on the TypeBuilder using
5977 (TypeContainer::GetClassBases): Implement. Essentially the code from the
5978 methods in RootContext, only ported to be part of TypeContainer.
5980 (TypeContainer::GetInterfaceOrClass): Ditto.
5982 (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
5984 * interface.cs (Interface::DefineInterface): New method. Does exactly
5985 what RootContext.CreateInterface did earlier, only it takes care of nested types
5988 (Interface::GetInterfaces): Move from RootContext here and port.
5990 (Interface::GetInterfaceByName): Same here.
5992 * rootcontext.cs (ResolveTree): Re-write.

5997 (TypeContainer::Emit): Emit nested members too.
5999 * typemanager.cs (AddUserType): Do not make use of the FullName property,
6000 instead just use the name argument passed in as it is already fully
6003 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
6004 to TypeContainer mapping to see if a type is user-defined.
6006 * class.cs (TypeContainer::CloseType): Implement.
6008 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
6009 the default constructor.
6011 (TypeContainer::Populate): Fix minor bug which led to creating default constructors
6014 (Constructor::IsDefault): Fix up logic to determine if it is the default constructor
6016 * interface.cs (CloseType): Create the type here.
6018 * rootcontext.cs (CloseTypes): Re-write to recursively close types by running through
6021 Remove all the methods which are now in TypeContainer.
6023 2001-10-10 Ravi Pratap <ravi@ximian.com>
6025 * delegate.cs (Define): Re-write bits to define the delegate
6028 2001-10-10 Miguel de Icaza <miguel@ximian.com>
6030 * makefile: Renamed the compiler to `mcs.exe' instead of compiler.exe
6032 * expression.cs (ImplicitReferenceConversion): handle null as well
6033 as a source to convert to any reference type.
6035 * statement.cs (Return): Perform any implicit conversions to
6036 expected return type.
6038 Validate use of return statement.
6040 * codegen.cs (EmitContext): Pass the expected return type here.
6042 * class.cs (Method, Constructor, Property): Pass expected return
6043 type to EmitContext.
6045 2001-10-09 Miguel de Icaza <miguel@ximian.com>
6047 * expression.cs: Make DoResolve take an EmitContext instead of a
6050 Replaced `l' and `location' for `loc', for consistency.
6052 (Error, Warning): Remove unneeded Tc argument.
6054 * assign.cs, literal.cs, constant.cs: Update to new calling
6057 * codegen.cs: EmitContext now contains a flag indicating whether
6058 code is being generated in a static method or not.
6060 * cs-parser.jay: DecomposeQI, new function that replaces the old
6061 QualifiedIdentifier. Now we always decompose the assembled
6062 strings from qualified_identifier productions into a group of
6065 2001-10-08 Miguel de Icaza <miguel@ximian.com>
6067 * rootcontext.cs: Deal with field-less struct types correctly now
6068 by passing the size option to Define Type.
6070 * class.cs: Removed hack that created one static field.
6072 2001-10-07 Miguel de Icaza <miguel@ximian.com>
6074 * statement.cs: Moved most of the code generation here.
6076 2001-10-09 Ravi Pratap <ravi@ximian.com>
6078 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
6081 (ElementAccess): Remove useless bits for now - keep checks as the spec
6084 2001-10-08 Ravi Pratap <ravi@ximian.com>
6086 * expression.cs (ElementAccess::DoResolve): Remove my crap code
6087 and start performing checks according to the spec.
6089 2001-10-07 Ravi Pratap <ravi@ximian.com>
6091 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
6092 rank_specifiers instead.
6094 (rank_specifiers): Change the order in which the rank specifiers are stored
6096 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
6098 * expression.cs (ElementAccess): Implement the LValue interface too.
6100 2001-10-06 Ravi Pratap <ravi@ximian.com>
6102 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
6103 except that user defined conversions are not included.
6105 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
6106 perform the conversion of the return type, if necessary.
6108 (New::DoResolve): Check whether we are creating an array or an object
6109 and accordingly do the needful.
6111 (New::Emit): Same here.
6113 (New::DoResolve): Implement guts of array creation.
6115 (New::FormLookupType): Helper function.
6117 2001-10-07 Miguel de Icaza <miguel@ximian.com>
6119 * codegen.cs: Removed most of the code generation here, and move the
6120 corresponding code generation bits to the statement classes.
6122 Added support for try/catch/finalize and throw.
6124 * cs-parser.jay: Added support for try/catch/finalize.
6126 * class.cs: Catch static methods having the flags override,
6127 virtual or abstract.
6129 * expression.cs (UserCast): This user cast was not really doing
6130 what it was supposed to do. Which is to be born in fully resolved
6131 state. Parts of the resolution were being performed at Emit time!
6135 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6137 * expression.cs: Implicity convert the result from UserCast.
6139 2001-10-05 Ravi Pratap <ravi@ximian.com>
6141 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
6142 prevented it from working correctly.
6144 (ConvertExplicit): Make the first try, a call to ConvertImplicitStandard, not
6145 merely ConvertImplicit.
6147 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6149 * typemanager.cs: Make the LookupTypeContainer function static,
6150 and not per-instance.
6152 * class.cs: Make static FindMembers (the one that takes a Type
6155 * codegen.cs: Add EmitForeach here.
6157 * cs-parser.jay: Make foreach a toplevel object instead of the
6158 inline expansion, as we need to perform semantic analysis on it.
6160 2001-10-05 Ravi Pratap <ravi@ximian.com>
6162 * expression.cs (Expression::ImplicitUserConversion): Rename to
6163 UserDefinedConversion.
6165 (Expression::UserDefinedConversion): Take an extra argument specifying
6166 whether we look for explicit user conversions too.
6168 (Expression::ImplicitUserConversion): Make it a call to UserDefinedConversion.

6177 * expression.cs (Cast): Record location info.
6179 (Expression::ConvertExplicit): Take location argument.
6181 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
6182 to determine if we are doing explicit conversions.
6184 (UserCast::Emit): Update accordingly.
6186 (Expression::ConvertExplicit): Report an error if everything fails.
6188 * ../errors/cs0030.cs : Add.
6190 2001-10-04 Miguel de Icaza <miguel@ximian.com>
6192 * modifiers.cs: If the ABSTRACT keyword is present, also set the
6193 virtual and newslot bits.
6195 * class.cs (TypeContainer::RegisterRequiredImplementations):
6196 Record methods we need.
6198 (TypeContainer::MakeKey): Helper function to make keys for
6199 MethodBases, since the Methodbase key is useless.
6201 (TypeContainer::Populate): Call RegisterRequiredImplementations
6202 before defining the methods.
6204 Create a mapping for method_builders_to_methods ahead of time
6205 instead of inside a tight loop.
6207 (::RequireMethods): Accept an object as the data to set into the
6208 hashtable so we can report interface vs abstract method mismatch.
6210 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6212 * report.cs: Make all of it static.
6214 * rootcontext.cs: Drop object_type and value_type computations, as
6215 we have those in the TypeManager anyways.
6217 Drop report instance variable too, now it is a global.
6219 * driver.cs: Use try/catch on command line handling.
6221 Add --probe option to debug the error reporting system with a test
6224 * report.cs: Add support for exiting program when a probe
6225 condition is reached.
6227 2001-10-03 Ravi Pratap <ravi@ximian.com>
6229 * expression.cs (Binary::DoNumericPromotions): Fix the case when
6230 we do a forcible conversion regardless of type, to check if
6231 ForceConversion returns a null.
6233 (Binary::error19): Use location to report error.
6235 (Unary::error23): Use location here too.
6237 * ../errors/cs0019.cs : Check in.
6239 * ../errors/cs0023.cs : Check in.
6241 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
6242 case of a non-null MethodInfo object with a length of 0 !
6244 (Binary::ResolveOperator): Flag error if overload resolution fails to find
6245 an applicable member - according to the spec :-)
6246 Also fix logic to find members in base types.
6248 (Unary::ResolveOperator): Same here.
6250 (Unary::report23): Change name to error23 and make first argument a TypeContainer
6251 as I was getting thoroughly confused between this and error19 :-)
6253 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
6254 (::FindMostEncompassedType): Implement.
6255 (::FindMostEncompassingType): Implement.
6256 (::StandardConversionExists): Implement.
6258 (UserImplicitCast): Re-vamp. We now need info about most specific
6259 source and target types so that we can do the necessary conversions.
6261 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
6262 mathematical union with no duplicates.
6264 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6266 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
6267 in order from base classes to child classes, so that we can in
6268 child classes look up in our parent for method names and
6269 attributes (required for handling abstract, virtual, new, override
6270 constructs: we need to instrospect our base class, and if we dont
6271 populate the classes in order, the introspection might be
6272 incorrect. For example, a method could query its parent before
6273 the parent has any methods and would determine that the parent has
6274 no abstract methods (while it could have had them)).
6276 (RootContext::CreateType): Record the order in which we define the
6279 2001-10-02 Miguel de Icaza <miguel@ximian.com>
6281 * class.cs (TypeContainer::Populate): Also method definitions can
6282 fail now, keep track of this.
6284 (TypeContainer::FindMembers): Implement support for
6285 DeclaredOnly/noDeclaredOnly flag.
6287 (Constructor::Emit) Return the ConstructorBuilder.
6289 (Method::Emit) Return the MethodBuilder.
6290 Check for abstract or virtual methods to be public.
6292 * rootcontext.cs (RootContext::CreateType): Register all the
6293 abstract methods required for the class to be complete and the
6294 interface methods that must be implemented.
6296 * cs-parser.jay: Report error 501 (method requires body if it is
6297 not marked abstract or extern).
6299 * expression.cs (TypeOf::Emit): Implement.
6301 * typemanager.cs: runtime_handle_type, new global type.
6303 * class.cs (Property::Emit): Generate code for properties.
6305 2001-10-02 Ravi Pratap <ravi@ximian.com>
6307 * expression.cs (Unary::ResolveOperator): Find operators on base type
6308 too - we now conform exactly to the spec.
6310 (Binary::ResolveOperator): Same here.
6312 * class.cs (Operator::Define): Fix minor quirk in the tests.
6314 * ../errors/cs0215.cs : Added.
6316 * ../errors/cs0556.cs : Added.
6318 * ../errors/cs0555.cs : Added.
6320 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6322 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
6323 single integer which is really efficient
6325 2001-10-01 Ravi Pratap <ravi@ximian.com>
6327 * expression.cs (Expression::ImplicitUserConversion): Use location
6328 even in the case when we are examining True operators.
6330 * class.cs (Operator::Define): Perform extensive checks to conform
6331 with the rules for operator overloading in the spec.
6333 * expression.cs (Expression::ImplicitReferenceConversion): Implement
6334 some of the other conversions mentioned in the spec.
6336 * typemanager.cs (array_type): New static member for the System.Array built-in
6339 (cloneable_interface): For System.ICloneable interface.
6341 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
6342 we start resolving the tree and populating types.
6344 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
6346 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6348 * expression.cs (Expression::ExprClassFromMemberInfo,
6349 Expression::Literalize): Create literal expressions from
6350 FieldInfos which are literals.
6352 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
6353 type casts, because they were wrong. The test suite in tests
6356 (ImplicitNumericConversion): ushort to ulong requires a widening
6359 Int32 constant to long requires widening cast as well.
6361 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
6362 for integers because the type on the stack is not i4.
6364 2001-09-30 Miguel de Icaza <miguel@ximian.com>
6366 * expression.cs (report118): require location argument.
6368 * parameter.cs: Do not dereference potential null value.
6370 * class.cs: Catch methods that lack the `new' keyword when
6371 overriding a name. Report warnings when `new' is used without
6372 anything being there to override.
6374 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
6376 * class.cs: Only add constructor to hashtable if it is non-null
6377 (as now constructors can fail on define).
6379 (TypeManager, Class, Struct): Take location arguments.
6381 Catch field instance initialization in structs as errors.
6383 accepting_filter: a new filter for FindMembers that is static so
6384 that we dont create an instance per invocation.
6386 (Constructor::Define): Catch errors where a struct constructor is
6389 * cs-parser.jay: Pass location information for various new
6392 * delegate.cs (Delegate): take a location argument.
6394 * driver.cs: Do not call EmitCode if there were problesm in the
6395 Definition of the types, as many Builders wont be there.
6397 * decl.cs (Decl::Decl): Require a location argument.
6399 * cs-tokenizer.cs: Handle properly hex constants that can not fit
6400 into integers, and find the most appropiate integer for it.
6402 * literal.cs: Implement ULongLiteral.
6404 * rootcontext.cs: Provide better information about the location of
6405 failure when CreateType fails.
6407 2001-09-29 Miguel de Icaza <miguel@ximian.com>
6409 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
6412 * expression.cs (Binary::CheckShiftArguments): Add missing type
6414 (Binary::ResolveOperator): Add type to the logical and and logical
6415 or, Bitwise And/Or and Exclusive Or code paths, it was missing
6418 (Binary::DoNumericPromotions): In the case where either argument
6419 is ulong (and most signed types combined with ulong cause an
6420 error) perform implicit integer constant conversions as well.
6422 2001-09-28 Miguel de Icaza <miguel@ximian.com>
6424 * expression.cs (UserImplicitCast): Method should always be
6426 (Invocation::BetterConversion): Simplified test for IntLiteral.
6428 (Expression::ImplicitNumericConversion): Split this routine out.
6429 Put the code that performs implicit constant integer conversions
6432 (Expression::Resolve): Become a wrapper around DoResolve so we can
6433 check eclass and type being set after resolve.
6435 (Invocation::Badness): Remove this dead function
6437 (Binary::ResolveOperator): Do not compute the expensive argumnets
6438 unless we have a union for it.
6440 (Probe::Emit): Is needs to do an isinst and then
6441 compare against null.
6443 (::CanConvert): Added Location argument. If the Location argument
6444 is null (Location.Null), then we do not report errors. This is
6445 used by the `probe' mechanism of the Explicit conversion. We do
6446 not want to generate an error for something that the user
6447 explicitly requested to be casted. But the pipeline for an
6448 explicit cast first tests for potential implicit casts.
6450 So for now, if the Location is null, it means `Probe only' to
6451 avoid adding another argument. Might have to revise this
6454 (ClassCast): New class used to type cast objects into arbitrary
6455 classes (used in Explicit Reference Conversions).
6457 Implement `as' as well.
6459 Reverted all the patches from Ravi below: they were broken:
6461 * The use of `level' as a mechanism to stop recursive
6462 invocations is wrong. That was there just to catch the
6463 bug with a strack trace but not as a way of addressing
6466 To fix the problem we have to *understand* what is going
6467 on and the interactions and come up with a plan, not
6468 just get things going.
6470 * The use of the type conversion cache that I proposed
6471 last night had an open topic: How does this work across
6472 protection domains. A user defined conversion might not
6473 be public in the location where we are applying the
6474 conversion, a different conversion might be selected
6475 (ie, private A->B (better) but public B->A (worse),
6476 inside A, A->B applies, but outside it, B->A will
6479 * On top of that (ie, even if the above is solved),
6480 conversions in a cache need to be abstract. Ie, `To
6481 convert from an Int to a Short use an OpcodeCast', not
6482 `To convert from an Int to a Short use the OpcodeCast on
6483 the variable 5' (which is what this patch was doing).
6485 2001-09-28 Ravi Pratap <ravi@ximian.com>
6487 * expression.cs (Invocation::ConversionExists): Re-write to use
6488 the conversion cache
6490 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
6491 cache all conversions done, not just user-defined ones.
6493 (Invocation::BetterConversion): The real culprit. Use ConversionExists
6494 to determine if a conversion exists instead of acutually trying to
6495 perform the conversion. It's faster too.
6497 (Expression::ConvertExplicit): Modify to use ConversionExists to check
6498 and only then attempt the implicit conversion.
6500 2001-09-28 Ravi Pratap <ravi@ximian.com>
6502 * expression.cs (ConvertImplicit): Use a cache for conversions
6503 already found. Check level of recursion and bail out if necessary.
6505 2001-09-28 Miguel de Icaza <miguel@ximian.com>
6507 * typemanager.cs (string_concat_string_string, string_concat_object_object):
6508 Export standard methods that we expect for string operations.
6510 * statement.cs (Block::UsageWarning): Track usage of variables and
6511 report the errors for not used variables.
6513 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
6516 2001-09-27 Miguel de Icaza <miguel@ximian.com>
6518 * codegen.cs: remove unnneded code
6520 * expression.cs: Removed BuiltinTypeAccess class
6522 Fix the order in which implicit conversions are
6525 The previous fixed dropped support for boxed conversions (adding a
6526 test to the test suite now)
6528 (UserImplicitCast::CanConvert): Remove test for source being null,
6529 that code is broken. We should not feed a null to begin with, if
6530 we do, then we should track the bug where the problem originates
6531 and not try to cover it up here.
6533 Return a resolved expression of type UserImplicitCast on success
6534 rather than true/false. Ravi: this is what I was talking about,
6535 the pattern is to use a static method as a "constructor" for
6538 Also, do not create arguments until the very last minute,
6539 otherwise we always create the arguments even for lookups that
6540 will never be performed.
6542 (UserImplicitCast::Resolve): Eliminate, objects of type
6543 UserImplicitCast are born in a fully resolved state.
6545 * typemanager.cs (InitCoreTypes): Init also value_type
6548 * expression.cs (Cast::Resolve): First resolve the child expression.
6550 (LValue): Add new method AddressOf to be used by
6553 Change the argument of Store to take an EmitContext instead of an
6554 ILGenerator, because things like FieldExpr need to be able to call
6555 their children expression to generate the instance code.
6557 (Expression::Error, Expression::Warning): Sugar functions for
6560 (Expression::MemberLookup): Accept a TypeContainer instead of a
6561 Report as the first argument.
6563 (Expression::ResolvePrimary): Killed. I still want to improve
6564 this as currently the code is just not right.
6566 (Expression::ResolveMemberAccess): Simplify, but it is still
6569 (Unary::Resolve): Catch errors in AddressOf operators.
6571 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
6572 index to a byte for the short-version, or the compiler will choose
6573 the wrong Emit call, which generates the wrong data.
6575 (ParameterReference::Emit, ::Store): same.
6577 (FieldExpr::AddressOf): Implement.
6579 * typemanager.cs: TypeManager: made public variable instead of
6582 * driver.cs: document --fatal.
6584 * report.cs (ErrorMessage, WarningMessage): new names for the old
6585 Error and Warning classes.
6587 * cs-parser.jay (member_access): Turn built-in access to types
6588 into a normal simplename
6590 2001-09-27 Ravi Pratap <ravi@ximian.com>
6592 * expression.cs (Invocation::BetterConversion): Fix to cope
6593 with q being null, since this was introducing a bug.
6595 * expression.cs (ConvertImplicit): Do built-in conversions first.
6597 2001-09-27 Ravi Pratap <ravi@ximian.com>
6599 * expression.cs (UserImplicitCast::Resolve): Fix bug.
6601 2001-09-27 Ravi Pratap <ravi@ximian.com>
6603 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
6604 I had introduced long ago (what's new ?).
6606 * expression.cs (UserImplicitCast::CanConvert): Static method to do
6607 the work of all the checking.
6608 (ConvertImplicit): Call CanConvert and only then create object if necessary.
6609 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
6611 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
6612 that is the right way.
6614 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
6615 overloading resolution. Use everywhere instead of cutting and pasting code.
6617 (Binary::ResolveOperator): Use MakeUnionSet.
6619 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
6620 we have to convert to bool types. Not complete yet.
6622 2001-09-27 Miguel de Icaza <miguel@ximian.com>
6624 * typemanager.cs (TypeManager::CSharpName): support ushort.
6626 * expression.cs (Expression::TryImplicitIntConversion): Attempts
6627 to provide an expression that performsn an implicit constant int
6628 conversion (section 6.1.6).
6629 (Expression::ConvertImplicitRequired): Reworked to include
6630 implicit constant expression conversions.
6632 (Expression::ConvertNumericExplicit): Finished.
6634 (Invocation::Emit): If InstanceExpression is null, then it means
6635 that we perform a call on this.
6637 2001-09-26 Miguel de Icaza <miguel@ximian.com>
6639 * expression.cs (Unary::Emit): Remove some dead code.
6640 (Probe): Implement Resolve and Emit for `is'.
6641 (Expression::ConvertImplicitRequired): Attempt to do constant
6642 expression conversions here. Maybe should be moved to
6643 ConvertImplicit, but I am not sure.
6644 (Expression::ImplicitLongConstantConversionPossible,
6645 Expression::ImplicitIntConstantConversionPossible): New functions
6646 that tell whether is it possible to apply an implicit constant
6647 expression conversion.

6652 * cs-parser.jay: Update operator constants.
6654 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs

6660 ones that the spec expects (as we are just stringizing the
6663 * expression.cs (Unary::ResolveOperator): Fix bug: Use
6664 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
6665 previous usage did only work for our methods.
6666 (Expression::ConvertImplicit): Handle decimal implicit numeric
6667 conversions as well.
6668 (Expression::InternalTypeConstructor): Used to invoke constructors
6669 on internal types for default promotions.
6671 (Unary::Emit): Implement special handling for the pre/post
6672 increment/decrement for overloaded operators, as they need to have
6673 the same semantics as the other operators.
6675 (Binary::ResolveOperator): ditto.
6676 (Invocation::ConversionExists): ditto.
6677 (UserImplicitCast::Resolve): ditto.
6679 2001-09-26 Ravi Pratap <ravi@ximian.com>
6681 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded

6686 (Invocation::OverloadResolve): Ditto.
6687 (Invocation::BetterFunction, BetterConversion, ConversionExists): Ditto.

6693 * assign.cs (Assign): Make it inherit from ExpressionStatement.
6695 * expression.cs (ExpressionStatement): New base class used for
6696 expressions that can appear in statements, so that we can provide
6697 an alternate path to generate expression that do not leave a value
6700 (Expression::Emit, and all the derivatives): We no longer return
6701 whether a value is left on the stack or not. Every expression
6702 after being emitted leaves a single value on the stack.
6704 * codegen.cs (EmitContext::EmitStatementExpression): Use the
6705 facilties of ExpressionStatement if possible.
6707 * cs-parser.jay: Update statement_expression.

6715 * expression.cs (Binary::ResolveOperator): Had forgottten to set
6716 the type of the expression to the return type of the method if

6728 (ConvertImplicit): Do user-defined conversion if it exists.
6730 2001-09-24 Miguel de Icaza <miguel@ximian.com>
6732 * assign.cs: track location.
6733 (Resolve): Use implicit conversions on assignment.
6735 * literal.cs: Oops. Not good, Emit of short access values should

6738 * expression.cs (Unary::Emit): Emit code for -expr.
6740 (Unary::ResolveOperator): Handle `Substract' for non-constants
6741 (substract from zero from the non-constants).

6776 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
6777 Also take an additional TypeContainer argument.
6779 * All over : Pass in TypeContainer as argument to OverloadResolve.
6781 * typemanager.cs (CSharpName): Update to check for the string type and return

6798 * typemanager.cs: declare and load enum_type, delegate_type and
6801 * expression.cs (Expression::Emit): Now emit returns a value that
6802 tells whether a value is left on the stack or not. This strategy
6803 might be reveted tomorrow with a mechanism that would address
6804 multiple assignments.
6805 (Expression::report118): Utility routine to report mismatches on
6808 (Unary::Report23): Report impossible type/operator combination
6811 (Unary::IsIncrementableNumber): Whether the type can be

6856 * expression.cs: Instead of having FIXMEs in the Resolve
6857 functions, throw exceptions so it is obvious that we are facing a
6860 * cs-parser.jay (invocation_expression): Pass Location information.
6862 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
6863 Use a basename for those routines because .NET does not like paths

6869 2001-09-19 Miguel de Icaza <miguel@ximian.com>
6871 * typemanager.cs (TypeManager::CoreLookupType): A function to make sure that we
6872 are loading the correct data types (throws an exception if not).

6875 * expression.cs (Unary::ResolveOperator): return the child
6876 expression for expressions which are just +expr.
6877 (Unary::ResolveOperator): Return negative literals for -LITERAL
6878 expressions (otherwise they are Unary {Literal}).
6879 (Invocation::Badness): Take into account `Implicit constant
6880 expression conversions'.
6882 * literal.cs (LongLiteral): Implement long literal class.
6883 (IntLiteral): export the `Value' of the intliteral.
6885 2001-09-19 Ravi Pratap <ravi@ximian.com>

6900 * expression.cs (Unary::Resolve): Implement.
6901 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
6902 operators are found instead of making noise ;-)
6903 (Unary::ResolveOperator): New method to do precisely the same thing which
6904 Binary::ResolveOperator does for Binary expressions.
6905 (Unary.method, .Arguments): Add.
6906 (Unary::OperName): Implement.
6907 (Unary::ForceConversion): Copy and Paste !
6909 * class.cs (Operator::Define): Fix a small bug for the case when we have
6912 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
6913 for the inbuilt operators. Only overloading works for now ;-)
6915 2001-09-18 Miguel de Icaza <miguel@ximian.com>
6917 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
6918 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

6931 (FieldExpr::Emit): Implement.
6933 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
6934 the last instruction contains a return opcode to avoid generating
6935 the last `ret' instruction (this generates correct code, and it is
6936 nice to pass the peverify output).
6938 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
6939 initializer for static and instance variables.
6940 (Constructor::Emit): Allow initializer to be null in the case of
6941 static constructors. Only emit initializer for instance
6944 (TypeContainer::FindMembers): Return a null array if there are no

6954 * driver.cs: Stop compilation if there are parse errors.
6956 * cs-parser.jay (constructor_declaration): Provide default base

6959 initializers if none was specified.
6960 Catch the fact that constructors should not have parameters.
6962 * class.cs: Do not emit parent class initializers for static
6963 constructors, that should be flagged as an error.
6965 2001-09-18 Ravi Pratap <ravi@ximian.com>
6967 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
6968 Move back code into TypeContainer::Populate.

6997 (Expression::MemberLookup): Provide a version that allows to
6998 specify the MemberTypes and BindingFlags.
7000 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
7001 so it was not fetching variable information from outer blocks.
7003 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
7004 Beforefieldinit as it was buggy.
7006 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
7009 * class.cs (Constructor::Emit): Only emit if block is not null.
7010 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
7011 deal with this by semantically definining it as if the user had
7014 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
7015 constructors as we now "emit" them at a higher level.

7018 default constructors if none was provided.
7020 (ConstructorInitializer): Add methods Resolve and Emit.
7022 * expression.cs: Cast to ConstructorInfo instead of MethodInfo

7042 and Unary::Operator.
7044 * cs-parser.jay (operator_declaration, CheckBinaryOperator, CheckUnaryOperator): Update

7048 we have overloaded operators.
7049 (Binary::ResolveOperator): Implement the part which does the operator overload
7052 * class.cs (Operator::Emit): Implement.
7053 (TypeContainer::Emit): Emit the operators we have too.
7055 * expression.cs (Binary::Emit): Update to emit the appropriate code for
7056 the case when we have a user-defined operator.

7099 Load System assembly as well as part of the standard library.
7101 * report.cs: Allow throwing exceptions on errors for debugging.
7103 * modifiers.cs: Do not use `parent', instead use the real type
7104 container to evaluate permission settings.
7106 * class.cs: Put Ravi's patch back in. He is right, and we will
7107 have to cope with the
7109 2001-09-14 Ravi Pratap <ravi@ximian.com>
7111 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

7116 * driver.cs: Added --parse option that only parses its input files
7119 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
7120 incorrect. IsTopLevel is not used to tell whether an object is
7121 root_types or not (that can be achieved by testing this ==
7122 root_types). But to see if this is a top-level *class* (not
7123 necessarly our "toplevel" container).
7125 2001-09-14 Ravi Pratap <ravi@ximian.com>
7127 * enum.cs (Enum::Define): Modify to call the Lookup method on the
7128 parent instead of a direct call to GetType.
7130 2001-09-14 Ravi Pratap <ravi@ximian.com>
7132 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
7133 Modifiers.TypeAttr. This should just be a call to that method.
7135 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
7136 object so that we can determine if we are top-level or not.
7138 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
7141 * enum.cs (Enum::Define): Ditto.
7143 * modifiers.cs (FieldAttr): Re-write.
7145 * class.cs (TypeContainer::IsTopLevel): Change accessibility to public.
7146 (TypeContainer::HaveStaticConstructor): New property to provide access
7147 to precisely that info.
7149 * modifiers.cs (MethodAttr): Re-write.
7150 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
7152 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
7153 of top-level types as claimed.
7155 2001-09-13 Miguel de Icaza <miguel@ximian.com>
7157 * expression.cs (MemberLookup): Fruitless attempt to lookup
7158 constructors. Maybe I need to emit default constructors? That
7159 might be it (currently .NET emits this for me automatically).
7160 (Invocation::OverloadResolve): Cope with Arguments == null.
7161 (Invocation::EmitArguments): new function, shared by the new
7163 (Invocation::Emit): Handle static and instance methods. Emit
7164 proper call instruction for virtual or non-virtual invocations.
7165 (New::Emit): Implement.
7166 (New::Resolve): Implement.
7167 (MemberAccess:Resolve): Implement.

7175 SimpleLookup): Auxiliary routines to help parse a qualifier
7178 Update qualifier_identifier rule.
7180 * codegen.cs: Removed debugging messages.
7182 * class.cs: Make this a global thing, this acts just as a "key" to
7183 objects that we might have around.
7185 (Populate): Only initialize method_builders_to_methods once.
7187 * expression.cs (PropertyExpr): Initialize type from the
7190 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
7191 Resolve pattern. Attempt to implicitly convert value to boolean.
7194 * expression.cs: Set the type for the int32/int32 argument case.
7195 (Binary::ResolveOperator): Set the return type to boolean for
7196 comparission operators
7198 * typemanager.cs: Remove debugging print code.
7200 (Invocation::Resolve): resolve type.
7202 * class.cs: Allocate a MemberInfo of the correct size, as the code
7203 elsewhere depends on the test to reflect the correct contents.
7205 (Method::) Keep track of parameters, due to System.Reflection holes
7207 (TypeContainer::Populate): Keep track of MethodBuilders to Method
7210 (TypeContainer::FindMembers): Use ArrayList and then copy an array
7211 of the exact size and return that.
7213 (Class::LookupMethodByBuilder): New function that maps
7214 MethodBuilders to its methods. Required to locate the information
7215 on methods because System.Reflection bit us again.
7217 * support.cs: New file, contains an interface ParameterData and
7218 two implementations: ReflectionParameters and InternalParameters
7219 used to access Parameter information. We will need to grow this
7222 * expression.cs (Invocation::GetParameterData): implement a cache
7223 and a wrapper around the ParameterData creation for methods.
7224 (Invocation::OverloadResolve): Use new code.
7226 2001-09-13 Ravi Pratap <ravi@ximian.com>
7228 * class.cs (TypeContainer::EmitField): Remove and move into
7229 (Field::Define): here and modify accordingly.
7230 (Field.FieldBuilder): New member.
7231 (TypeContainer::Populate): Update accordingly.
7232 (TypeContainer::FindMembers): Implement.
7234 2001-09-13 Miguel de Icaza <miguel@ximian.com>
7236 * statement.cs: (VariableInfo::VariableType): New field to be
7237 initialized with the full type once it is resolved.
7239 2001-09-12 Miguel de Icaza <miguel@ximian.com>
7241 * parameter.cs (GetParameterInfo): Use a type cache to compute
7242 things only once, and to reuse this information
7244 * expression.cs (LocalVariableReference::Emit): Implement.

7535 will is used during the tree rewriting as we resolve them during

7662 * class.cs (Property): Revamp to use the convention of making fields readonly.

7711 and re-write the code in the actions to extract the specific and
7712 general catch clauses by being a little smart ;-)
7714 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
7715 Hooray, try and catch statements parse fine !

7719 * statement.cs (Block::GetVariableType): Fix logic to extract the type
7720 string from the hashtable of variables.

7773 instead of ignoring the rank_specifiers.
7774 (expression_list): Implement to collect the expressions

7779 (opt_array_initializer): Modify accordingly.

7810 generation from working. Also add some temporary debugging
7813 2001-08-24 Miguel de Icaza <miguel@ximian.com>

7816 beginning, will continue tomorrow with more touches of polish. We

7824 emission to keep a context. Most of the code generation will be

7847 move from Properties to public readonly fields.
7848 (Method::ParameterTypes): Returns the parameter types for the
7849 function, and implements a cache that will be useful later when I
7850 do error checking and the semantic analysis on the methods is
7852 (Constructor::GetCallingConvention): Renamed from CallingConvetion
7853 and made a method, optional argument tells whether this is a class
7854 or a structure to apply the `has-this' bit.
7855 (Method::GetCallingConvention): Implement, returns the calling
7857 (Method::Define): Defines the type, a second pass is performed
7858 later to populate the methods.
7860 (Constructor::ParameterTypes): implement a cache similar to the
7861 one on Method::ParameterTypes, useful later when we do semantic
7864 (TypeContainer::EmitMethod): New method. Emits methods.
7866 * expression.cs: Removed MethodGroup class from here.
7868 * parameter.cs (Parameters::GetCallingConvention): new method.

7875 (Constructor::CallingConvention): Returns the calling convention.
7876 (Constructor::ParameterTypes): Returns the constructor parameter
7879 (TypeContainer::AddConstructor): Keep track of default constructor
7880 and the default static constructor.
7882 (Constructor::) Another class that starts using `public readonly'
7883 instead of properties.
7885 (Constructor::IsDefault): Whether this is a default constructor.
7887 (Field::) use readonly public fields instead of properties also.
7889 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
7890 track of static constructors; If none is used, turn on
7891 BeforeFieldInit in the TypeAttributes.
7893 * cs-parser.jay (opt_argument_list): now the return can be null
7894 for the cases where there are no arguments.
7896 (constructor_declarator): If there is no implicit `base' or
7897 `this', then invoke the default parent constructor.
7899 * modifiers.cs (MethodAttr): New static function maps a set of
7900 modifiers flags into a MethodAttributes enum
7901 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
7902 MethodAttr, TypeAttr to represent the various mappings where the
7904 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
7906 2001-08-19 Miguel de Icaza <miguel@ximian.com>
7908 * parameter.cs (GetParameterInfo): Fix bug where there would be no
7911 * interface.cs (PopulateIndexer): Implemented the code generator
7912 for interface indexers.
7914 2001-08-17 Miguel de Icaza <miguel@ximian.com>
7916 * interface.cs (InterfaceMemberBase): Now we track the new status
7919 (PopulateProperty): Implement property population. Woohoo! Got
7920 Methods and Properties going today.
7922 Removed all the properties for interfaces, and replaced them with
7923 `public readonly' fields.
7925 2001-08-16 Miguel de Icaza <miguel@ximian.com>
7927 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
7928 initialize their hashtables/arraylists only when they are needed
7929 instead of doing this always.
7931 * parameter.cs: Handle refs and out parameters.
7933 * cs-parser.jay: Use an ArrayList to construct the arguments
7934 instead of the ParameterCollection, and then cast that to a
7937 * parameter.cs: Drop the use of ParameterCollection and use
7938 instead arrays of Parameters.
7940 (GetParameterInfo): Use the Type, not the Name when resolving
7943 2001-08-13 Miguel de Icaza <miguel@ximian.com>
7945 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
7946 and instead use public readonly fields.
7948 * class.cs: Put back walking code for type containers.
7950 2001-08-11 Miguel de Icaza <miguel@ximian.com>
7952 * class.cs (MakeConstant): Code to define constants.
7954 * rootcontext.cs (LookupType): New function. Used to locate types
7957 2001-08-08 Miguel de Icaza <miguel@ximian.com>
7959 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
7960 this System.Reflection code is. Kudos to Microsoft
7962 * typemanager.cs: Implement a type cache and avoid loading all
7963 types at boot time. Wrap in LookupType the internals. This made
7964 the compiler so much faster. Wow. I rule!
7966 * driver.cs: Make sure we always load mscorlib first (for
7967 debugging purposes, nothing really important).
7969 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
7970 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
7972 * rootcontext.cs: Lookup types on their namespace; Lookup types
7973 on namespaces that have been imported using the `using' keyword.
7975 * class.cs (TypeContainer::TypeAttr): Virtualize.
7976 (Class::TypeAttr): Return attributes suitable for this bad boy.
7977 (Struct::TypeAttr): ditto.
7978 Handle nested classes.
7979 (TypeContainer::) Remove all the type visiting code, it is now
7980 replaced with the rootcontext.cs code
7982 * rootcontext.cs (GetClassBases): Added support for structs.
7984 2001-08-06 Miguel de Icaza <miguel@ximian.com>
7986 * interface.cs, statement.cs, class.cs, parameter.cs,
7987 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
7988 Drop use of TypeRefs, and use strings instead.
7990 2001-08-04 Miguel de Icaza <miguel@ximian.com>
7994 * class.cs (Struct::Struct): set the SEALED flags after
7995 checking the modifiers.
7996 (TypeContainer::TypeAttr): new property, returns the
7997 TypeAttributes for a class.
7999 * cs-parser.jay (type_list): Oops, list production was creating a
8000 new list of base types.
8002 * rootcontext.cs (StdLib): New property.
8003 (GetInterfaceTypeByName): returns an interface by type name, and
8004 encapsulates error handling here.
8005 (GetInterfaces): simplified.
8006 (ResolveTree): Encapsulated all the tree resolution here.
8007 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
8010 * driver.cs: Add support for --nostdlib, to avoid loading the
8012 (Main): Do not put tree resolution here.
8014 * rootcontext.cs: Beginning of the class resolution.
8016 2001-08-03 Miguel de Icaza <miguel@ximian.com>
8018 * rootcontext.cs: Provide better error reporting.
8020 * cs-parser.jay (interface_base): set our $$ to be interfaces.
8022 * rootcontext.cs (CreateInterface): Handle the case where there
8023 are no parent interfaces.
8025 (CloseTypes): Routine to flush types at the end.
8026 (CreateInterface): Track types.
8027 (GetInterfaces): Returns an array of Types from the list of
8030 * typemanager.c (AddUserType): Mechanism to track user types (puts
8031 the type on the global type hash, and allows us to close it at the
8034 2001-08-02 Miguel de Icaza <miguel@ximian.com>
8036 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
8037 RecordInterface instead.
8039 * cs-parser.jay: Updated to reflect changes above.
8041 * decl.cs (Definition): Keep track of the TypeBuilder type that
8042 represents this type here. Not sure we will use it in the long
8043 run, but wont hurt for now.
8045 * driver.cs: Smaller changes to accomodate the new code.
8047 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
8050 * rootcontext.cs (CreateInterface): New method, used to create
8051 the System.TypeBuilder type for interfaces.
8052 (ResolveInterfaces): new entry point to resolve the interface
8054 (CodeGen): Property, used to keep track of the code generator.
8056 2001-07-26 Miguel de Icaza <miguel@ximian.com>
8058 * cs-parser.jay: Add a second production for delegate_declaration
8061 (enum_body): Put an opt_comma here instead of putting it on
8062 enum_body or enum_member_declarations so we can handle trailing
8063 commas on enumeration members. Gets rid of a shift/reduce.
8065 (type_list): Need a COMMA in the middle.
8067 (indexer_declaration): Tell tokenizer to recognize get/set
8069 * Remove old targets.
8071 * Re-add the parser target.
8073 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8075 * cs-parser.jay: Add precendence rules for a number of operators
8076 ot reduce the number of shift/reduce conflicts in the grammar.
8078 2001-07-17 Miguel de Icaza <miguel@ximian.com>
8080 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
8083 Get rid of old crufty code.
8085 * rootcontext.cs: Use this to keep track of the parsed
8086 representation and the defined types available to the program.
8088 * gen-treedump.cs: adjust for new convention.
8090 * type.cs: Split out the type manager, and the assembly builder
8093 * typemanager.cs: the type manager will live here now.
8095 * cil-codegen.cs: And the code generator here.
8097 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
8099 * makefile: Fixed up for easy making.
8101 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8103 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
8106 (unary_expression): Expand pre_increment_expression and
8107 post_decrement_expression to reduce a shift/reduce.
8109 2001-07-11 Simon Cozens
8111 * cs-tokenizer.cs: Hex numbers should begin with a 0.
8113 Improve allow_keyword_as_indent name.
8115 2001-06-19 Miguel de Icaza <miguel@ximian.com>
8117 * Adjustments for Beta2.
8119 2001-06-13 Miguel de Icaza <miguel@ximian.com>
8121 * decl.cs: Added `Define' abstract method.
8122 (InTransit): new property, used to catch recursive definitions.
8124 * interface.cs: Implement `Define'.
8126 * modifiers.cs: Map Modifiers.constants to
8127 System.Reflection.TypeAttribute flags.
8129 * class.cs: Keep track of types and user-defined types.
8130 (BuilderInit): New method for creating an assembly
8131 (ResolveType): New function to launch the resolution process, only
8132 used by interfaces for now.
8134 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
8135 that are inserted into the name space.
8137 2001-06-08 Miguel de Icaza <miguel@ximian.com>
8139 * ARGH. I have screwed up my tree so many times due to the use of
8140 rsync rather than using CVS. Going to fix this at once.
8142 * driver.cs: Objetify driver. Load assemblies, use assemblies to
8145 2001-06-07 Miguel de Icaza <miguel@ximian.com>
8147 * Experiment successful: Use System.Type rather that our own
8150 2001-05-25 Miguel de Icaza <miguel@ximian.com>
8152 * cs-parser.jay: Removed nsAliases from here.
8154 Use new namespaces, handle `using XXX;'
8156 * namespace.cs: Reimplemented namespace handling, use a recursive
8157 definition of the class. Now we can keep track of using clauses
8158 and catch invalid using clauses.
8160 2001-05-24 Miguel de Icaza <miguel@ximian.com>
8162 * gen-treedump.cs: Adapted for all the renaming.
8164 * expression.cs (Expression): this class now has a Type property
8165 which returns an expression Type.
8167 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
8168 `Type', as this has a different meaning now in the base
8170 2001-05-22 Miguel de Icaza <miguel@ximian.com>
8172 * interface.cs, class.cs: Removed from all the sources the
8173 references to signature computation, as we can not do method
8174 signature computation during the parsing time, as we are not
8175 trying to solve at that point distinguishing:
8179 void a (NS.Blah x) {}
8182 Which depending on the context might be valid or not, as we do not
8183 know if Blah is the same thing as NS.Blah at that point.
8185 * Redid everything so the code uses TypeRefs now instead of
8186 Types. TypeRefs are just temporary type placeholders, that need
8187 to be resolved. They initially have a pointer to a string and the
8188 current scope in which they are used. This is used later by the
8189 compiler to resolve the reference to an actual Type.
8191 * DeclSpace is no longer a CIR.Type, and neither are
8192 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
8193 are all DeclSpaces, but no Types.
8195 * type.cs (TypeRefManager): This implements the TypeRef manager,
8196 which keeps track of all the types that need to be resolved after
8197 the parsing has finished.
8199 2001-05-13 Miguel de Icaza <miguel@ximian.com>
8201 * ARGH. We are going to have to store `foreach' as a class rather
8202 than resolving it, as we need to verify error 1579 after name
8203 resolution. *OR* we could keep a flag that says `This request to
8204 IEnumerator comes from a foreach statement' which we can then use
8205 to generate the error.
8207 2001-05-10 Miguel de Icaza <miguel@ximian.com>
8209 * class.cs (TypeContainer.AddMethod): we now add methods to the
8210 MethodGroup instead of the method hashtable.
8212 * expression.cs: Add MethodGroup abstraction, which gets us one
8213 step closer to the specification in the way we handle method
8216 * cs-parser.jay (primary_expression): qualified_identifier now
8217 tried to match up an identifier to a local variable reference or
8218 to a parameter reference.
8220 current_local_parameters is now a parser global variable that
8221 points to the current parameters for the block, used during name
8224 (property_declaration): Now creates an implicit `value' argument to
8227 2001-05-09 Miguel de Icaza <miguel@ximian.com>
8229 * parameter.cs: Do not use `param' arguments as part of the
8230 signature, per the spec.
8232 2001-05-08 Miguel de Icaza <miguel@ximian.com>
8234 * decl.cs: Base class for classes, structs and interfaces. This
8235 is the "Declaration Space"
8237 * cs-parser.jay: Use CheckDef for checking declaration errors
8238 instead of having one on each function.
8240 * class.cs: Factor out some code for handling error handling in
8241 accordance to the "Declarations" section in the "Basic Concepts"
8242 chapter in the ECMA C# spec.
8244 * interface.cs: Make all interface member classes derive from
8245 InterfaceMemberBase.
8247 2001-05-07 Miguel de Icaza <miguel@ximian.com>
8249 * Many things: all interfaces are parsed and generated in
8250 gen-treedump. Support for member variables, constructors,
8251 destructors, properties, constants is there.
8253 Beginning of the IL backend, but very little done, just there for
8256 2001-04-29 Miguel de Icaza <miguel@ximian.com>
8258 * cs-parser.jay: Fix labeled statement.
8260 * cs-tokenizer.cs (escape): Escape " and ' always.
8261 ref_line, ref_name: keep track of the line/filename as instructed
8262 by #line by the compiler.
8265 2001-04-27 Miguel de Icaza <miguel@ximian.com>
8267 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
8268 to match the values in System.CodeDOM.
8270 Divid renamed to Divide.
8272 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
8274 (Statements.set): remove.
8276 * System.CodeDOM/CodeCatchClause.cs: always have a valid
8279 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
8280 falseStatements always have valid values.
8282 * cs-parser.jay: Use System.CodeDOM now.
