3 In addition to a nice code cleanup, this gives us a performance
4 increase of about 1.4% on GNU/Linux - not much, but it's already
5 half a second for the self-hosting MCS compilation.
7 * typemanager.cs (IMemberFinder): New interface. It is used by
8 TypeManager.FindMembers to call FindMembers on a TypeContainer,
9 Enum, Delegate or Interface.
10 (TypeManager.finder_to_member_finder): New PtrHashtable.
11 (TypeManager.finder_to_container): Removed.
12 (TypeManager.finder_to_delegate): Removed.
13 (TypeManager.finder_to_interface): Removed.
14 (TypeManager.finder_to_enum): Removed.

18 * delegate.cs (Delegate): Implement IMemberFinder.
20 * enum.cs (Enum): Implement IMemberFinder.
22 * class.cs (TypeContainer): Implement IMemberFinder.
24 2002-08-12 Martin Baulig <martin@gnome.org>
26 * ecore.cs (TypeExpr.DoResolveType): Mark this as virtual.
28 2002-08-12 Martin Baulig <martin@gnome.org>
30 * ecore.cs (ITypeExpression): New interface for expressions which
32 (TypeExpression): Renamed to TypeLookupExpression.
33 (Expression.DoResolve): If we're doing a types-only lookup, the
34 expression must implement the ITypeExpression interface and we
35 call DoResolveType() on it.
36 (SimpleName): Implement the new ITypeExpression interface.
37 (SimpleName.SimpleNameResolve): Removed the ec.OnlyLookupTypes
38 hack, the situation that we're only looking up types can't happen
39 anymore when this method is called. Moved the type lookup code to
40 DoResolveType() and call it.
41 (SimpleName.DoResolveType): This ITypeExpression interface method
42 is now doing the types-only lookup.
43 (TypeExpr, TypeLookupExpression): Implement ITypeExpression.
44 (ResolveFlags): Added MaskExprClass.
46 * expression.cs (MemberAccess): Implement the ITypeExpression
48 (MemberAccess.DoResolve): Added support for a types-only lookup
49 when we're called via ITypeExpression.DoResolveType().
50 (ComposedCast): Implement the ITypeExpression interface.
52 * codegen.cs (EmitContext.OnlyLookupTypes): Removed. Call
53 Expression.Resolve() with ResolveFlags.Type instead.
55 2002-08-12 Martin Baulig <martin@gnome.org>
57 * interface.cs (Interface.Define): Apply attributes.
59 * attribute.cs (Attribute.ApplyAttributes): Added support for
62 2002-08-11 Martin Baulig <martin@gnome.org>
64 * statement.cs (Block.Emit): Only check the "this" variable if we
65 do not always throw an exception.
67 * ecore.cs (PropertyExpr.DoResolveLValue): Implemented, check
68 whether the property has a set accessor.
70 2002-08-11 Martin Baulig <martin@gnome.org>
72 Added control flow analysis support for structs.
74 * ecore.cs (ResolveFlags): Added `DisableFlowAnalysis' to resolve
75 with control flow analysis turned off.
76 (IVariable): New interface.
77 (SimpleName.SimpleNameResolve): If MemberAccess.ResolveMemberAccess
78 returns an IMemberExpr, call DoResolve/DoResolveLValue on it.
79 (FieldExpr.DoResolve): Resolve the instance expression with flow
80 analysis turned off and do the definite assignment check after the
81 resolving when we know what the expression will resolve to.
83 * expression.cs (LocalVariableReference, ParameterReference):
84 Implement the new IVariable interface, only call the flow analysis
85 code if ec.DoFlowAnalysis is true.
86 (This): Added constructor which takes a Block argument. Implement
87 the new IVariable interface.
88 (MemberAccess.DoResolve, MemberAccess.DoResolveLValue): Call
89 DoResolve/DoResolveLValue on the result of ResolveMemberLookup().
90 This does the definite assignment checks for struct members.
92 * class.cs (Constructor.Emit): If this is a non-static `struct'
93 constructor which doesn't have any initializer, call
94 Block.AddThisVariable() to tell the flow analysis code that all
95 struct elements must be initialized before control returns from
98 * statement.cs (MyStructInfo): New public class.
99 (UsageVector.this [VariableInfo vi]): Added `int field_idx'
100 argument to this indexer. If non-zero, check an individual struct
101 member, not the whole struct.
102 (FlowBranching.CheckOutParameters): Check struct members.
103 (FlowBranching.IsVariableAssigned, SetVariableAssigned): Added
104 overloaded versions of these methods which take an additional
105 `int field_idx' argument to check struct members.
106 (FlowBranching.IsParameterAssigned, SetParameterAssigned): Added
107 overloaded versions of these methods which take an additional
108 `string field_name' argument to check struct member.s
109 (VariableInfo): Implement the IVariable interface.
110 (VariableInfo.StructInfo): New public property. Returns the
111 MyStructInfo instance of the variable if it's a struct or null.
112 (Block.AddThisVariable): New public method. This is called from
113 Constructor.Emit() for non-static `struct' constructor which do
114 not have any initializer. It creates a special variable for the
115 "this" instance variable which will be checked by the flow
116 analysis code to ensure that all of the struct's fields are
117 initialized before control returns from the constructor.
118 (UsageVector): Added support for struct members. If a
119 variable/parameter is a struct with N members, we reserve a slot
120 in the usage vector for each member. A struct is considered fully
121 initialized if either the struct itself (slot 0) or all its
122 members are initialized.
124 2002-08-08 Martin Baulig <martin@gnome.org>
126 * driver.cs (Driver.MainDriver): Only report an error CS5001
127 if there were no compilation errors.
129 * codegen.cs (EmitContext.EmitContext): Use the DeclSpace's
130 `UnsafeContext' property to determine whether the parent is in
131 unsafe context rather than checking the parent's ModFlags:
132 classes nested in an unsafe class are unsafe as well.
134 2002-08-08 Martin Baulig <martin@gnome.org>
136 * statement.cs (UsageVector.MergeChildren): Distinguish between
137 `Breaks' and `Returns' everywhere, don't set `Breaks' anymore if
138 we return. Added test17() and test18() to test-154.cs.
140 2002-08-08 Martin Baulig <martin@gnome.org>
142 * typemanager.cs (TypeManager.FilterWithClosure): If we have
143 Family access, make sure the invoking type isn't a subclass of the
144 queried type (that'd be a CS1540).
146 * ecore.cs (Expression.MemberLookup): Added overloaded version of
147 this method which takes an additional `Type invocation_type'.
149 * expression.cs (BaseAccess.DoResolve): Use the base type as
150 invocation and query type.
151 (MemberAccess.DoResolve): If the lookup failed and we're about to
152 report a CS0122, try a lookup with the ec.ContainerType - if this
153 succeeds, we must report a CS1540.
155 2002-08-08 Martin Baulig <martin@gnome.org>
157 * ecore.cs (IMemberExpr): Added `bool IsInstance' property.
158 (MethodGroupExpr): Implement the IMemberExpr interface.
160 * expression (MemberAccess.ResolveMemberAccess): No need to have
161 any special code for MethodGroupExprs anymore, they're now
164 2002-08-08 Martin Baulig <martin@gnome.org>
166 * typemanager.cs (TypeManager.FilterWithClosure): Check Assembly,
167 Family, FamANDAssem and FamORAssem permissions.
168 (TypeManager.IsSubclassOrNestedChildOf): New public method.
170 2002-08-08 Martin Baulig <martin@gnome.org>
172 * statement.cs (FlowBranchingType): Added LOOP_BLOCK.
173 (UsageVector.MergeChildren): `break' breaks unless we're in a switch
176 Thu Aug 8 10:28:07 CEST 2002 Paolo Molaro <lupus@ximian.com>
178 * driver.cs: implemented /resource option to embed managed resources.
180 2002-08-07 Martin Baulig <martin@gnome.org>
182 * class.cs (FieldBase.Initializer): Renamed to `init' and made private.
183 (FieldBase.HasFieldInitializer): New public property.
184 (FieldBase.GetInitializerExpression): New public method. Resolves and
185 returns the field initializer and makes sure it is only resolved once.
186 (TypeContainer.EmitFieldInitializers): Call
187 FieldBase.GetInitializerExpression to get the initializer, this ensures
188 that it isn't resolved multiple times.
190 * codegen.cs (EmitContext): Added `bool IsFieldInitialier'. This tells
191 the resolving process (SimpleName/MemberLookup) that we're currently
192 emitting a field initializer (which must not access any instance members,
193 this is an error CS0236).
195 * ecore.cs (SimpleName.Error_ObjectRefRequired): Added EmitContext
196 argument, if the `IsFieldInitializer' flag is set, we must report and
197 error CS0236 and not an error CS0120.
199 2002-08-07 Martin Baulig <martin@gnome.org>
201 * ecore.cs (IMemberExpr): New public interface.
202 (FieldExpr, PropertyExpr, EventExpr): Implement IMemberExpr.
203 (SimpleName.SimpleNameResolve): Call MemberAccess.ResolveMemberAccess
204 if the expression is an IMemberExpr.
206 * expression.cs (MemberAccess.ResolveMemberAccess): Allow `left'
207 to be null, implicitly default to `this' if we're non-static in
208 this case. Simplified the code a lot by using the new IMemberExpr
209 interface. Also fixed bug #28176 here.
211 2002-08-06 Martin Baulig <martin@gnome.org>
213 * cs-parser.jay (SimpleLookup): Removed. We need to create
214 ParameterReferences during semantic analysis so that we can do a
215 type-only search when resolving Cast, TypeOf and SizeOf.
216 (block): Pass the `current_local_parameters' to the Block's
219 * class.cs (ConstructorInitializer): Added `Parameters parameters'
220 argument to the constructor.
221 (ConstructorInitializer.Resolve): Create a temporary implicit
222 block with the parameters.
224 * ecore.cs (SimpleName.SimpleNameResolve): Resolve parameter
225 references here if we aren't doing a type-only search.
227 * statement.cs (Block): Added constructor which takes a
228 `Parameters parameters' argument.
229 (Block.Parameters): New public property.
231 * support.cs (InternalParameters.Parameters): Renamed `parameters'
232 to `Parameters' and made it public readonly.

236 * ecore.cs (Expression.Warning): Made this public as well.
238 * report.cs (Report.Debug): Print the contents of collections.
240 2002-08-06 Martin Baulig <martin@gnome.org>
242 * ecore.cs (Expression.ResolveFlags): New [Flags] enum. This is
243 used to tell Resolve() which kinds of expressions it may return.
244 (Expression.Resolve): Added overloaded version of this method which
245 takes a `ResolveFlags flags' argument. This can be used to tell
246 Resolve() which kinds of expressions it may return. Reports a
248 (Expression.ResolveWithSimpleName): Removed, use Resolve() with
249 ResolveFlags.SimpleName.
250 (Expression.Error118): Added overloaded version of this method which
251 takes a `ResolveFlags flags' argument. It uses the flags to determine
252 which kinds of expressions are allowed.
254 * expression.cs (Argument.ResolveMethodGroup): New public method.
255 Resolves an argument, but allows a MethodGroup to be returned.
256 This is used when invoking a delegate.
258 * TODO: Updated a bit.
260 2002-08-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
262 Fixed compilation with csc.
264 * ecore.cs: Expression.Error made public. Is this correct? Should
265 Warning be made public too?
267 * expression.cs: use ea.Location instead of ea.loc.
268 [FIXME: Filed as bug #28607: MCS must report these errors.]
270 2002-08-06 Martin Baulig <martin@gnome.org>
272 * ecore.cs (Expression.loc): Moved the location here instead of
273 duplicating it in all derived classes.
274 (Expression.Location): New public property.
275 (Expression.Error, Expression.Warning): Made them non-static and
276 removed the location argument.
277 (Expression.Warning): Added overloaded version which takes an
278 `int level' argument.
279 (Expression.Error118): Make this non-static and removed the
280 expression and location arguments.
281 (TypeExpr): Added location argument to the constructor.
283 * expression.cs (StaticCallExpr): Added location argument to
285 (Indirection, PointerArithmetic): Likewise.

299 while resolving the corresponding blocks.
301 * interface.cs (Interface.GetInterfaceTypeByName): Actually report
302 an error, don't silently return null.

307 (LabeledStatement): Pass the location to the constructor.
308 (LabeledStatement.HasBeenReferenced): New property.
309 (LabeledStatement.Resolve): Set it to true here.
311 * statement.cs (Return.Emit): Return success even after reporting
312 a type mismatch error (CS0126 or CS0127), this is what csc does and
313 it avoids confusing the users with any consecutive errors.
315 2002-08-05 Martin Baulig <martin@gnome.org>
317 * enum.cs (Enum.LookupEnumValue): Catch circular definitions.
319 * const.cs (Const.LookupConstantValue): Catch circular definitions.
321 * expression.cs (MemberAccess.DoResolve): Silently return if an
322 error has already been reported.

334 * expression.cs (Binary.ResolveOperator): When combining delegates,
335 they must have the same type.
337 2002-08-05 Martin Baulig <martin@gnome.org>
339 * typemanager.cs (TypeManager.GetArgumentTypes): Don't call
340 PropertyInfo.GetIndexParameters() on dynamic types, this doesn't
341 work with the ms runtime and we also don't need it: if we're a
342 PropertyBuilder and not in the `indexer_arguments' hash, then we
343 are a property and not an indexer.
345 * class.cs (TypeContainer.AsAccessible): Use Type.IsArray,
346 Type.IsPointer and Type.IsByRef instead of Type.HasElementType
347 since the latter one doesn't work with the ms runtime.

358 and it's not marked abstract or extern.
359 (PropertyBase): New abstract base class for Property and Indexer.
360 (PropertyBase.CheckBase): Moved here from Property and made it work
362 (PropertyBase.Emit): Moved here from Property.Emit, Indexer.Emit is
363 the same so we can reuse it there.
364 (Property, Indexer): Derive from PropertyBase.
365 (MethodSignature.inheritable_property_signature_filter): New delegate
366 to find properties and indexers.
368 * decl.cs (MemberCore.CheckMethodAgainstBase): Added `string name'
369 argument and improved error reporting.

400 top-level types and private for nested types.
401 (Enum.DefineType): Compute the correct visibility.
403 * modifiers.cs (Modifiers.TypeAttr): Added a version of this
404 function which takes a `bool is_toplevel' instead of a TypeContainer.
406 * typemanager.cs (TypeManager.IsBuiltinType): `void' is also a
409 2002-08-02 Martin Baulig <martin@gnome.org>
411 * expression.cs (LocalVariableReferenc): Added constructor which
412 takes additional `VariableInfo vi' and `bool is_readonly' arguments.
413 (LocalVariableReference.IsReadOnly): New property.
414 (LocalVariableReference.DoResolveLValue): Report a CS1604 if the
415 variable is readonly, use our own readonly flag to do this; you can
416 use the new constructor to get a writable reference to a read-only
419 * cs-parser.jay (foreach_statement, using_statement): Get a writable
420 reference to the local variable.
422 2002-08-01 Miguel de Icaza <miguel@ximian.com>
424 * rootcontext.cs (ResolveCore): Also include System.Exception
426 * statement.cs (Block.Emit): Do not emit the dead-code warnings if
427 we reach an EmptyStatement.
429 (Catch.DoResolve, Throw.DoResolve): Throwing the System.Exception
432 * expression.cs (Binary.ResolveOperator): Check error result in
435 use brtrue/brfalse directly and avoid compares to null.
437 2002-08-02 Martin Baulig <martin@gnome.org>
439 * class.cs (TypeContainer.Define): Define all nested interfaces here.
440 Fixes bug #28407, added test-155.cs.
442 2002-08-01 Martin Baulig <martin@gnome.org>

521 To get debugging messages, compile mcs with /define:MCS_DEBUG and
522 then use this argument.
524 * report.cs (Report.Debug): Renamed to conditional to "MCS_DEBUG".
526 * makefile.gnu (MCS_FLAGS): Include $(MCS_DEFINES), the user may
527 use this to specify /define options.

595 2002-07-27 Martin Baulig <martin@gnome.org>
597 * class.cs (MethodData.Define): Put back call to
598 TypeManager.AddMethod(), accidentally commented this out.
600 * report.cs (Debug): New public method to print debugging information,
601 this is `[Conditional ("DEBUG")]'.
603 2002-07-26 Martin Baulig <martin@gnome.org>
605 * cs-parser.jay (CSharpParser): Added `Stack switch_stack'.
606 (switch_statement): Push the current_block to the switch_stack and
607 pop it again when we're done with the switch.
608 (switch_section): The new block is a child of the current_block.
609 Fixes bug #24007, added test-152.cs.
611 2002-07-27 Martin Baulig <martin@gnome.org>
613 * expression.cs (Invocation.EmitArguments): When calling a varargs
614 function with only its fixed arguments, we need to pass an empty
617 2002-07-27 Martin Baulig <martin@gnome.org>
619 Mono 0.13 has been released.
621 2002-07-25 Miguel de Icaza <miguel@ximian.com>
623 * driver.cs: Rename --resource to --linkres, because that is what
624 we do currently, we dont support --resource yet.
626 * cs-tokenizer.cs: Fix test for reporting endif mismatches.
628 2002-07-25 Martin Baulig <martin@gnome.org>
630 * class.cs (MethodData): New public class. This is a `method builder'
631 class for a method or one accessor of a Property/Indexer/Event.
632 (MethodData.GetMethodFlags): Moved here from MemberBase.
633 (MethodData.ApplyAttributes): Likewise.
634 (MethodData.ApplyObsoleteAttribute): Likewise.
635 (MethodData.ApplyConditionalAttribute): Likewise.
636 (MethodData.ApplyDllImportAttribute): Likewise.
637 (MethodData.CheckAbstractAndExternal): Likewise.
638 (MethodData.Define): Formerly knows as MemberBase.DefineMethod().
639 (MethodData.Emit): Formerly known as Method.Emit().
640 (MemberBase): Moved everything which was specific to a single
641 accessor/method to MethodData.
642 (Method): Create a new MethodData and call Define() and Emit() on it.
643 (Property, Indexer, Event): Create a new MethodData objects for each
644 accessor and call Define() and Emit() on them.
646 2002-07-25 Martin Baulig <martin@gnome.org>
648 Made MethodCore derive from MemberBase to reuse the code from there.
649 MemberBase now also checks for attributes.
651 * class.cs (MethodCore): Derive from MemberBase, not MemberCore.
652 (MemberBase.GetMethodFlags): Moved here from class Method and marked
654 (MemberBase.DefineAccessor): Renamed to DefineMethod(), added
655 `CallingConventions cc' and `Attributes opt_attrs' arguments.
656 (MemberBase.ApplyAttributes): New virtual method; applies the
657 attributes to a method or accessor.
658 (MemberBase.ApplyObsoleteAttribute): New protected virtual method.
659 (MemberBase.ApplyConditionalAttribute): Likewise.
660 (MemberBase.ApplyDllImportAttribute): Likewise.
661 (MemberBase.CheckAbstractAndExternal): Likewise.
662 (MethodCore.ParameterTypes): This is now a property instead of a
663 method, it's initialized from DoDefineParameters().
664 (MethodCore.ParameterInfo): Removed the set accessor.
665 (MethodCore.DoDefineParameters): New protected virtual method to
666 initialize ParameterTypes and ParameterInfo.
667 (Method.GetReturnType): We can now simply return the MemberType.
668 (Method.GetMethodFlags): Override the MemberBase version and add
669 the conditional flags.
670 (Method.CheckBase): Moved some code from Define() here, call
671 DoDefineParameters() here.
672 (Method.Define): Use DoDefine() and DefineMethod() from MemberBase
673 here to avoid some larger code duplication.
674 (Property.Emit, Indexer.Emit): Call CheckAbstractAndExternal() to
675 ensure that abstract and external accessors don't declare a body.
677 * attribute.cs (Attribute.GetValidPieces): Make this actually work:
678 `System.Attribute.GetCustomAttributes (attr.Type)' does a recursive
679 lookup in the attribute's parent classes, so we need to abort as soon
680 as we found the first match.
681 (Attribute.Obsolete_GetObsoleteMessage): Return the empty string if
682 the attribute has no arguments.
684 * typemanager.cs (TypeManager.AddMethod): Now takes a MemberBase instead
687 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
689 * cs-parser.jay: reverted previous patch.
691 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
693 * cs-parser.jay: fixed bug #22119.
695 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
697 * attribute.cs: fixed compilation. The error was:
698 "attribute.cs(571,17): error CS0177: The out parameter 'is_error' must
699 be assigned to before control leaves the current method."
700 [FIXME: Filed as bug #28186: MCS must report this error.]
702 2002-07-25 Martin Baulig <martin@gnome.org>
704 * attribute.cs (Attribute.Conditional_GetConditionName): New static
705 method to pull the condition name ouf of a Conditional attribute.
706 (Attribute.Obsolete_GetObsoleteMessage): New static method to pull
707 the obsolete message and error flag out of an Obsolete attribute.
709 * class.cs (Method.GetMethodFlags): New public method to get the
710 TypeManager.MethodFlags for this method.
711 (Method.ApplyConditionalAttribute, Method.ApplyObsoleteAttribute): New
713 (Method.Define): Get and apply the Obsolete and Conditional attributes;
714 if we're overriding a virtual function, set the new private variable
715 `parent_method'; call the new TypeManager.AddMethod().
717 * typemanager.cs (TypeManager.AddMethod): New static method. Stores
718 the MethodBuilder and the Method in a PtrHashtable.
719 (TypeManager.builder_to_method): Added for this purpose.
720 (TypeManager.MethodFlags): Added IsObsoleteError.
721 (TypeManager.GetMethodFlags): Added `Location loc' argument. Lookup
722 Obsolete and Conditional arguments in MethodBuilders. If we discover
723 an Obsolete attribute, emit an appropriate warning 618 / error 619 with
724 the message from the attribute.
726 2002-07-24 Martin Baulig <martin@gnome.org>
728 * cs-tokenizer.cs: Eat up trailing whitespaces and one-line comments in
729 preprocessor directives, ensure that the argument to #define/#undef is
730 exactly one identifier and that it's actually an identifier.
732 Some weeks ago I did a `#define DEBUG 1' myself and wondered why this
735 2002-07-24 Martin Baulig <martin@gnome.org>
737 * statement.cs (Foreach.ForeachHelperMethods): Added `Type element_type',
738 initialize it to TypeManager.object_type in the constructor.
739 (Foreach.GetEnumeratorFilter): Set `hm.element_type' to the return type
740 of the `hm.get_current' method if we're using the collection pattern.
741 (Foreach.EmitCollectionForeach): Use `hm.element_type' as the source type
742 for the explicit conversion to make it work when we're using the collection
743 pattern and the `Current' property has a different return type than `object'.
746 2002-07-24 Martin Baulig <martin@gnome.org>
748 * delegate.cs (Delegate.VerifyMethod): Simply return null if the method
749 does not match, but don't report any errors. This method is called in
750 order for all methods in a MethodGroupExpr until a matching method is
751 found, so we don't want to bail out if the first method doesn't match.
752 (NewDelegate.DoResolve): If none of the methods in the MethodGroupExpr
753 matches, report the 123. Fixes #28070.
755 2002-07-24 Martin Baulig <martin@gnome.org>
757 * expression.cs (ArrayAccess.EmitStoreOpcode): Moved the
758 TypeManager.TypeToCoreType() to the top of the method so the
759 following equality checks will work. Fixes #28107.
761 2002-07-24 Martin Baulig <martin@gnome.org>
763 * cfold.cs (ConstantFold.DoConstantNumericPromotions): "If either
764 operand is of type uint, and the other operand is of type sbyte,
765 short or int, the operands are converted to type long." -
766 Actually do what this comment already told us. Fixes bug #28106,
769 2002-07-24 Martin Baulig <martin@gnome.org>
771 * class.cs (MethodBase): New abstract class. This is now a base
772 class for Property, Indexer and Event to avoid some code duplication
773 in their Define() and DefineMethods() methods.
774 (MethodBase.DoDefine, MethodBase.DefineAccessor): Provide virtual
775 generic methods for Define() and DefineMethods().
776 (FieldBase): Derive from MemberBase, not MemberCore.
777 (Property): Derive from MemberBase, not MemberCore.
778 (Property.DefineMethod): Moved all the code from this method to the
779 new MethodBase.DefineAccessor(), just call it with appropriate
781 (Property.Define): Call the new Property.DoDefine(), this does some
782 sanity checks and we don't need to duplicate the code everywhere.
783 (Event): Derive from MemberBase, not MemberCore.
784 (Event.Define): Use the new MethodBase.DefineAccessor() to define the
785 accessors, this will also make them work with interface events.
786 (Indexer): Derive from MemberBase, not MemberCore.
787 (Indexer.DefineMethod): Removed, call MethodBase.DefineAccessor() insstead.
788 (Indexer.Define): Use the new MethodBase functions.
790 * interface.cs (InterfaceEvent.InterfaceEvent): Added `Location loc'
791 argument to the constructor.
792 (Interface.FindMembers): Added support for interface events.
793 (Interface.PopluateEvent): Implemented.
795 Added test-149.cs for this. This also fixes bugs #26067 and #24256.
797 2002-07-22 Miguel de Icaza <miguel@ximian.com>
799 * class.cs (TypeContainer.AddMethod): Adding methods do not use IsValid,
800 but this is required to check for a method name being the same as
801 the containing class.
805 2002-07-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
807 * interface.cs: initialize variable.
809 2002-07-23 Martin Baulig <martin@gnome.org>
811 Implemented the IndexerName attribute in interfaces.
813 * class.cs (TypeContainer.DefineIndexers): Don't set the indexer
814 name if this is an explicit interface implementation.
815 (Indexer.InterfaceIndexerName): New public variable. If we're
816 implementing an interface indexer, this is the IndexerName in that
817 interface. Otherwise, it's the IndexerName.
818 (Indexer.DefineMethod): If we're implementing interface indexer,
819 set InterfaceIndexerName. Use the new Pending.IsInterfaceIndexer
820 and Pending.ImplementIndexer methods.
821 (Indexer.Define): Also define the PropertyBuilder if we're
822 implementing an interface indexer and this is neither an explicit
823 interface implementation nor do the IndexerName match the one in
826 * pending.cs (TypeAndMethods): Added `MethodInfo [] need_proxy'.
827 If a method is defined here, then we always need to create a proxy
828 for it. This is used when implementing interface indexers.
829 (Pending.IsInterfaceIndexer): New public method.
830 (Pending.ImplementIndexer): New public method.
831 (Pending.InterfaceMethod): Added `MethodInfo need_proxy' argument.
832 This is used when implementing interface indexers to define a proxy
834 (Pending.VerifyPendingMethods): Look in the `need_proxy' array and
835 define a proxy if necessary.
837 * interface.cs (Interface.IndexerName): New public variable.
838 (Interface.PopulateIndexer): Set the IndexerName.
839 (Interface.DefineIndexers): New private method. Populate all the
840 indexers and make sure their IndexerNames match.
842 * typemanager.cs (IndexerPropertyName): Added support for interface
845 2002-07-22 Martin Baulig <martin@gnome.org>
847 * codegen.cs (EmitContext.HasReturnLabel): New public variable.
848 (EmitContext.EmitTopBlock): Always mark the ReturnLabel and emit a
849 ret if HasReturnLabel.
850 (EmitContext.TryCatchLevel, LoopBeginTryCatchLevel): New public
853 * statement.cs (Do.Emit, While.Emit, For.Emit, Foreach.Emit): Save
854 and set the ec.LoopBeginTryCatchLevel.
855 (Try.Emit): Increment the ec.TryCatchLevel while emitting the block.
856 (Continue.Emit): If the ec.LoopBeginTryCatchLevel is smaller than
857 the current ec.TryCatchLevel, the branch goes out of an exception
858 block. In this case, we need to use Leave and not Br.
860 2002-07-22 Martin Baulig <martin@gnome.org>
862 * statement.cs (Try.Emit): Emit an explicit ret after the end of the
863 block unless the block does not always return or it is contained in
864 another try { ... } catch { ... } block. Fixes bug #26506.
865 Added verify-1.cs to the test suite.
867 2002-07-22 Martin Baulig <martin@gnome.org>
869 * statement.cs (Switch.TableSwitchEmit): If we don't have a default,
870 then we do not always return. Fixes bug #24985.
872 2002-07-22 Martin Baulig <martin@gnome.org>
874 * expression.cs (Invocation.OverloadedResolve): Do the BetterFunction()
875 lookup on a per-class level; ie. walk up the class hierarchy until we
876 found at least one applicable method, then choose the best among them.
877 Fixes bug #24463 and test-29.cs.
879 2002-07-22 Martin Baulig <martin@gnome.org>
881 * typemanager.cs (TypeManager.ArrayContainsMethod): Don't check the
882 return types of the methods. The return type is not part of the
883 signature and we must not check it to make the `new' modifier work.
884 Fixes bug #27999, also added test-147.cs.
885 (TypeManager.TypeToCoreType): Added TypeManager.type_type.
887 * expression.cs (Invocation.DoResolve): Call TypeManager.TypeToCoreType()
888 on the method's return type.
890 2002-07-21 Martin Baulig <martin@gnome.org>
892 * assign.cs: Make this work if the rightmost source is a constant and
893 we need to do an implicit type conversion. Also adding a few more tests
894 to test-38.cs which should have caught this.
896 * makefile.gnu: Disable debugging, there's already the mcs-mono2.exe
897 target in the makefile for this. The makefile.gnu is primarily intended
898 for end-users who don't want to debug the compiler.
900 2002-07-21 Martin Baulig <martin@gnome.org>
902 * assign.cs: Improved the Assign class so it can now handle embedded
903 assignments (X = Y = Z = something). As a side-effect this'll now also
904 consume less local variables. test-38.cs now passes with MCS, added
905 a few new test cases to that test.
907 2002-07-20 Martin Baulig <martin@gnome.org>
909 * expression.cs (Binary.EmitBranchable): Emit correct unsigned branch
910 instructions. Fixes bug #27977, also added test-146.cs.
912 2002-07-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
914 * cs-tokenizer.cs: fixed getHex ().
916 2002-07-19 Martin Baulig <martin@gnome.org>
918 * expression.cs (Invocation.EmitParams): Use TypeManager.LookupType(),
919 not Type.GetType() to lookup the array type. This is needed when
920 we're constructing an array of a user-defined type.
921 (ArrayAccess.EmitDynamicInitializers): Only emit the Ldelema for
922 single-dimensional arrays, but also for single-dimensial arrays of
925 2002-07-19 Martin Baulig <martin@gnome.org>
927 * expression.cs (New.DoEmit): Create a new LocalTemporary each time
928 this function is called, it's not allowed to share LocalBuilders
931 2002-07-19 Martin Baulig <martin@gnome.org>
933 * expression.cs (Argument.Resolve): Report an error 118 when trying
934 to pass a type as argument.
936 2002-07-18 Martin Baulig <martin@gnome.org>
938 * ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
939 Conv_R_Un for the signed `long' type.
941 2002-07-15 Miguel de Icaza <miguel@ximian.com>
943 * expression.cs (MemberAccess.DoResolve): Do not reuse the field
944 `expr' for the temporary result, as that will fail if we do
945 multiple resolves on the same expression.
947 2002-07-05 Miguel de Icaza <miguel@ximian.com>
949 * ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
950 ec.TypeContainer for looking up aliases.
952 * class.cs (TypeContainer): Remove LookupAlias from here.
954 * decl.cs (DeclSpace); Move here.
956 2002-07-01 Miguel de Icaza <miguel@ximian.com>
958 * class.cs (FindMembers): Only call filter if the constructor
961 Also handle delegates in `NestedTypes' now. Now we will perform
962 type lookups using the standard resolution process. This also
965 * decl.cs (DeclSpace.ResolveType): New type resolution routine.
966 This uses Expressions (the limited kind that can be parsed by the
967 tree) instead of strings.
969 * expression.cs (ComposedCast.ToString): Implement, used to flag
970 errors since now we have to render expressions.
972 (ArrayCreation): Kill FormElementType. Use ComposedCasts in
975 * ecore.cs (SimpleName.ToString): ditto.
977 * cs-parser.jay: Instead of using strings to assemble types, use
978 Expressions to assemble the type (using SimpleName, ComposedCast,
979 MemberAccess). This should fix the type lookups in declarations,
980 because we were using a different code path for this.
982 * statement.cs (Block.Resolve): Continue processing statements
983 even when there is an error.
985 2002-07-17 Miguel de Icaza <miguel@ximian.com>
987 * class.cs (Event.Define): Also remove the `remove' method from
988 the list of pending items.
990 * expression.cs (ParameterReference): Use ldarg.N (0..3) to
991 generate more compact code.
993 2002-07-17 Martin Baulig <martin@gnome.org>
995 * const.cs (Const.LookupConstantValue): Add support for constant
996 `unchecked' and `checked' expressions.
997 Also adding test case test-140.cs for this.
999 2002-07-17 Martin Baulig <martin@gnome.org>
1001 * statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
1002 check whether mi.ReturnType implements the IEnumerator interface; the
1003 `==' and the IsAssignableFrom() will fail in this situation.
1005 2002-07-16 Ravi Pratap <ravi@ximian.com>
1007 * ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix
1010 2002-07-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1012 * expression.cs: fixed bug #27811.
1014 2002-07-14 Miguel de Icaza <miguel@ximian.com>
1016 * expression.cs (ParameterReference.AddressOf): Patch from Paolo
1017 Molaro: when we are a ref, the value already contains a pointer
1018 value, do not take the address of it.
1020 2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1021 * removed mb-parser.jay and mb-tokenizer.cs
1023 Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
1025 * expression.cs: check against the building corlib void type.
1027 Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
1029 * ecore.cs: fix for valuetype static readonly fields: when
1030 initializing them, we need their address, not the address of a copy.
1032 Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
1034 * typemanager.cs: register also enum_type in corlib.
1036 Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
1038 * class.cs: allow calling this (but not base) initializers in structs.
1040 Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
1042 * ecore.cs: make sure we compare against the building base types
1045 Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
1047 * typemanager.cs: fix TypeToCoreType() to handle void and object
1048 (corlib gets no more typerefs after this change).
1050 2002-07-12 Miguel de Icaza <miguel@ximian.com>
1052 * expression.cs (ArrayCreation.EmitArrayArguments): use
1053 Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
1055 (ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
1056 Conv_Ovf_I_Un for the array arguments. Even if C# allows longs as
1057 array indexes, the runtime actually forbids them.
1059 * ecore.cs (ExpressionToArrayArgument): Move the conversion code
1060 for array arguments here.
1062 * expression.cs (EmitLoadOpcode): System.Char is a U2, use that
1063 instead of the default for ValueTypes.
1065 (New.DoEmit): Use IsValueType instead of
1066 IsSubclassOf (value_type)
1067 (New.DoResolve): ditto.
1068 (Invocation.EmitCall): ditto.
1070 * assign.cs (Assign): ditto.
1072 * statement.cs (Unsafe): Ok, so I got the semantics wrong.
1073 Statements *are* currently doing part of their resolution during
1076 Expressions do always resolve during resolve, but statements are
1077 only required to propagate resolution to their children.
1079 2002-07-11 Miguel de Icaza <miguel@ximian.com>
1081 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
1083 (LoadAssembly): Do not add the dll if it is already specified
1085 (MainDriver): Add the System directory to the link path at the end,
1086 after all the other -L arguments.
1088 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
1089 wrong opcode for loading bytes and bools (ldelem.i1 instead of
1090 ldelem.u1) and using the opposite for sbytes.
1092 This fixes Digger, and we can finally run it.
1094 * driver.cs (UnixParseOption): Move the option parsing here.
1095 (CSCParseOption): Implement CSC-like parsing of options.
1097 We now support both modes of operation, the old Unix way, and the
1098 new CSC-like way. This should help those who wanted to make cross
1101 The only thing broken is that /r:, /reference: and /lib: are not
1102 implemented, because I want to make those have the same semantics
1103 as the CSC compiler has, and kill once and for all the confussion
1104 around this. Will be doing this tomorrow.
1106 * statement.cs (Unsafe.Resolve): The state is checked during
1107 resolve, not emit, so we have to set the flags for IsUnsfe here.
1109 2002-07-10 Miguel de Icaza <miguel@ximian.com>
1111 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
1112 not catch the Error_ObjectRefRequired in SimpleName (as it is
1113 possible to have a class/instance variable name that later gets
1114 deambiguated), we have to check this here.
1116 2002-07-10 Ravi Pratap <ravi@ximian.com>
1118 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
1119 make static and put into Expression.
1121 (Event.Define): Register the private field of the event with the
1122 TypeManager so that GetFieldFromEvent can get at it.
1124 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
1125 keep track of the private field associated with an event which
1128 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
1131 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
1133 2002-07-10 Miguel de Icaza <miguel@ximian.com>
1135 * expression.cs (Binary.EmitBranchable): this routine emits the
1136 Binary expression in a branchable context. This basically means:
1137 we need to branch somewhere, not just get the value on the stack.
1139 This works together with Statement.EmitBoolExpression.
1141 * statement.cs (Statement.EmitBoolExpression): Use
1144 2002-07-09 Miguel de Icaza <miguel@ximian.com>
1146 * statement.cs (For): Reduce the number of jumps in loops.
1148 (For): Implement loop inversion for the For statement.
1150 (Break): We can be breaking out of a Try/Catch controlled section
1151 (foreach might have an implicit try/catch clause), so we need to
1152 use Leave instead of Br.
1154 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
1155 now). If the instace expression supports IMemoryLocation, we use
1156 the AddressOf method from the IMemoryLocation to extract the
1157 address instead of emitting the instance.
1159 This showed up with `This', as we were emitting the instance
1160 always (Emit) instead of the Address of This. Particularly
1161 interesting when This is a value type, as we dont want the Emit
1162 effect (which was to load the object).
1164 2002-07-08 Miguel de Icaza <miguel@ximian.com>
1166 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
1168 * statement.cs (Checked): Set the CheckedState during the resolve
1169 process too, as the ConvCast operations track the checked state on
1170 the resolve process, and not emit.
1172 * cs-parser.jay (namespace_member_declaration): Flag that we have
1173 found a declaration when we do. This is used to flag error 1529
1175 * driver.cs: Report ok when we display the help only.
1177 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
1179 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
1181 2002-07-04 Miguel de Icaza <miguel@ximian.com>
1183 * cs-tokenizer.cs (define): We also have to track locally the
1184 defines. AllDefines is just used for the Conditional Attribute,
1185 but we also need the local defines for the current source code.
1187 2002-07-03 Miguel de Icaza <miguel@ximian.com>
1189 * statement.cs (While, For, Do): These loops can exit through a
1190 Break statement, use this information to tell whether the
1191 statement is the last piece of code.
1193 (Break): Flag that we break.
1195 * codegen.cs (EmitContexts): New `Breaks' state variable.
1197 2002-07-03 Martin Baulig <martin@gnome.org>
1199 * class.cs (TypeContainer.MethodModifiersValid): Allow override
1200 modifiers in method declarations in structs. Otherwise, you won't
1201 be able to override things like Object.Equals().
1203 2002-07-02 Miguel de Icaza <miguel@ximian.com>
1205 * class.cs (Method, Property, Indexer): Do not allow the public
1206 modifier to be used in explicit interface implementations.
1208 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
1209 override modifiers in method declarations in structs
1211 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
1213 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
1214 integer or real overflow, report an error
1216 2002-07-02 Martin Baulig <martin@gnome.org>
1218 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
1219 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
1220 to tell the runtime about our newly created System.Object and
1221 System.ValueType types.
1223 2002-07-02 Miguel de Icaza <miguel@ximian.com>
1225 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
1226 struct instead of Ldarg/Starg.
1228 2002-07-02 Martin Baulig <martin@gnome.org>
1230 * expression.cs (Indirection.Indirection): Call
1231 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
1233 2002-07-02 Martin Baulig <martin@gnome.org>
1235 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
1236 ValueType, call TypeManager.TypeToCoreType() on it.
1237 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
1238 the OpCodes.Newarr argument.
1240 2002-07-02 Martin Baulig <martin@gnome.org>
1242 * expression.cs (Invocation.EmitCall): When compiling corlib,
1243 replace all calls to the system's System.Array type to calls to
1244 the newly created one.
1246 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
1247 System.Array methods.
1248 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
1249 from the system's System.Array type which must be replaced.
1251 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
1253 * typemanager.cs: load unverifiable_code_ctor so we can build
1254 corlib using the correct type. Avoid using GetTypeCode() with
1256 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
1257 TypeManager.object_type to allow building corlib.
1259 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
1261 * ecore.cs: handle System.Enum separately in LoadFromPtr().
1263 2002-07-01 Martin Baulig <martin@gnome.org>
1265 * class.cs: Make the last change actually work, we need to check
1266 whether `ifaces != null' to avoid a crash.
1268 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
1270 * class.cs: when we build structs without fields that implement
1271 interfaces, we need to add the interfaces separately, since there is
1272 no API to both set the size and add the interfaces at type creation
1275 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
1277 * expression.cs: the dimension arguments to the array constructors
1278 need to be converted if they are a long.
1280 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
1282 * class.cs: don't emit ldarg.0 if there is no parent constructor
1283 (fixes showstopper for corlib).
1285 2002-06-29 Martin Baulig <martin@gnome.org>
1287 MCS now compiles corlib on GNU/Linux :-)
1289 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
1290 ie. check for MethodImplOptions.InternalCall.
1292 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
1293 and TypeManager.attribute_type are null, so we must explicitly check
1294 whether parent is not null to find out whether it's an attribute type.
1295 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
1296 and SetBuilder, not only if the property is neither abstract nor external.
1297 This is necessary to set the MethodImplOptions on the accessor methods.
1298 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
1299 SetBuilder, see Property.Emit().
1301 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
1302 populate "System.Object", "System.ValueType" and "System.Attribute" since
1303 they've already been populated from BootCorlib_PopulateCoreTypes().
1305 2002-06-29 Martin Baulig <martin@gnome.org>
1307 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
1308 is the NullLiteral, we also need to make sure that target_type is not
1311 2002-06-29 Martin Baulig <martin@gnome.org>
1313 * rootcontext.cs (RootContext.ResolveCore): We must initialize
1314 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
1315 before calling BootstrapCorlib_ResolveDelegate ().
1317 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1319 * statement.cs: fixed build-breaker. All tests passed ok.
1321 2002-06-27 Martin Baulig <martin@gnome.org>
1323 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
1324 for System.Decimal when compiling corlib.
1326 2002-06-27 Martin Baulig <martin@gnome.org>
1328 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
1329 switch blocks which contain nothing but a default clause.
1331 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
1333 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
1335 2002-06-27 Martin Baulig <martin@gnome.org>
1337 * ecore.cs (PropertyExpr.PropertyExpr): Call
1338 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
1340 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
1341 is already a TypeBuilder.
1343 2002-06-27 Martin Baulig <martin@gnome.org>
1345 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
1346 `target_type == TypeManager.array_type', not IsAssignableFrom() in
1347 the "from an array-type to System.Array" case. This makes it work
1348 when compiling corlib.
1350 2002-06-27 Martin Baulig <martin@gnome.org>
1352 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
1353 non-static PropertyExpr, set its InstanceExpression. This makes
1354 the `ICollection.Count' property work in System/Array.cs.
1356 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
1358 * driver.cs: Made error handling more consistent. Errors now
1359 tracked by Report class, so many methods which used to return int
1360 now return void. Main() now prints success/failure and
1361 errors/warnings message.
1363 Renamed '--probe' compiler argument to '--expect-error'. Removed
1364 the magic number return values (123 and 124). Now, if the
1365 expected error occurs, the compiler exits with success (exit value
1366 0). If the compilation completes without seeing that particular
1367 error, the compiler exits with failure (exit value 1). The
1368 makefile in mcs/errors has been changed to handle the new behaviour.
1370 * report.cs: Made 'expected error' number a property and renamed
1371 it from 'Probe' to 'ExpectedError'.
1373 * genericparser.cs: Removed error handling support, since it is
1374 now all done by Report class.
1376 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
1377 class, so parse() no longer returns an int.
1379 * namespace.cs: Use Report.Error instead of GenericParser.error
1381 2002-06-22 Miguel de Icaza <miguel@ximian.com>
1383 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
1384 TypeContainer.AddOperator): At the front of the list put the
1385 explicit implementations, so they get resolved/defined first.
1387 2002-06-21 Miguel de Icaza <miguel@ximian.com>
1389 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
1390 interface type is implemented by this TypeContainer. Used during
1391 explicit interface implementation.
1393 (Property.Define, Indexer.Define, Method.Define): Validate that
1394 the given interface in the explicit implementation is one of the
1395 base classes for the containing type.
1397 Also if we are explicitly implementing an interface, but there is
1398 no match in the pending implementation table, report an error.
1400 (Property.Define): Only define the property if we are
1401 not explicitly implementing a property from an interface. Use the
1402 correct name also for those properties (the same CSC uses,
1403 although that is really not needed).
1405 (Property.Emit): Do not emit attributes for explicitly implemented
1406 properties, as there is no TypeBuilder.
1408 (Indexer.Emit): ditto.
1410 Hiding then means that we do not really *implement* a pending
1411 implementation, which makes code fail.
1413 2002-06-22 Martin Baulig <martin@gnome.org>
1415 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
1416 the return value of Object.GetType(). [FIXME: we need to do this whenever
1417 we get a type back from the reflection library].
1419 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
1421 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
1423 2002-06-20 Miguel de Icaza <miguel@ximian.com>
1425 * attribute.cs: Return null if we can not look up the type.
1427 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
1428 the interface types found.
1430 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
1431 interface types found.
1433 * typemanager.cs (GetInterfaces): Make this routine returns alll
1434 the interfaces and work around the lame differences between
1435 System.Type and System.Reflection.Emit.TypeBuilder in the results
1436 result for GetInterfaces.
1438 (ExpandInterfaces): Given an array of interface types, expand and
1439 eliminate repeated ocurrences of an interface. This expands in
1440 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
1443 2002-06-21 Martin Baulig <martin@gnome.org>
1445 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
1448 2002-06-21 Martin Baulig <martin@gnome.org>
1450 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
1451 and called with one of the core types, return the corresponding typebuilder for
1454 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
1457 2002-06-21 Martin Baulig <martin@gnome.org>
1459 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
1460 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
1461 (Expression.ConvertReferenceExplicit): Likewise.
1463 * expression.cs (ElementAccess.DoResolve): Likewise.
1464 (ElementAccess.DoResolveLValue): Likewise.
1466 2002-06-10 Martin Baulig <martin@gnome.org>
1468 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
1469 add the "value" parameter to the parameter list.
1471 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
1474 2002-06-19 Miguel de Icaza <miguel@ximian.com>
1476 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
1477 the argument to an int, uint, long or ulong, per the spec. Also
1478 catch negative constants in array creation.
1480 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
1482 * class.cs: do not allow the same interface to appear twice in
1483 the definition list.
1485 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
1487 * ecore.cs: don't use ldlen with System.Array.
1489 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
1491 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
1493 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
1495 * modifiers.cs: produce correct field attributes for protected
1496 internal. Easy fix so miguel can work on ther harder stuff:-)
1498 2002-06-18 Miguel de Icaza <miguel@ximian.com>
1500 * pending.cs: New file. Move the code from class.cs here.
1501 Support clearning the pending flag for all methods (when not doing
1502 explicit interface implementation).
1504 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
1506 * rootcontext.cs: added a couple more types needed to bootstrap.
1508 2002-06-17 Miguel de Icaza <miguel@ximian.com>
1510 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
1511 constructor in the type, instead of any constructor in the type
1512 hierarchy. Thanks to Paolo for finding this bug (it showed up as
1513 a bug in the Mono runtime when applying the params attribute).
1515 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1516 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
1518 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
1520 * expression.cs (Unary.ResolveOperator): Use TypeManager
1521 to resolve the type.
1523 2002-06-13 Ravi Pratap <ravi@ximian.com>
1525 * cs-parser.jay (enum_member_declaration): Pass in the attributes
1528 * enum.cs (AddEnumMember): Add support to store the attributes associated
1529 with each member too.
1531 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
1532 field builders too - this takes care of the enum member case.
1534 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
1536 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
1537 address-of operator on both value types and pointers.
1539 2002-06-10 Martin Baulig <martin@gnome.org>
1541 * interface.cs (Interface.PopulateIndexer): Add the indexer's
1542 PropertyBuilder to the `property_builders' list.
1544 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
1545 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
1546 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
1547 find any indexers which are inherited from an interface.
1549 2002-06-09 Martin Baulig <martin@gnome.org>
1551 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
1552 the same type as the constant if necessary. There's also a test-130.cs
1555 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
1557 * typemanager.cs (TypeManager.ChangeType): Previously known as
1558 Enum.ChangeEnumType().
1560 2002-06-09 Martin Baulig <martin@gnome.org>
1562 * expression.cs (Cast.TryReduce): Added support for consts.
1564 2002-06-08 Ravi Pratap <ravi@ximian.com>
1566 * class.cs (Accessor): Hold attributes information so we can pass
1569 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
1570 Modify to pass in attributes attached to the methods.
1572 (add_accessor_declaration, remove_accessor_declaration): Ditto.
1574 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
1575 to handle the Accessor kind :-)
1577 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
1579 2002-06-08 Martin Baulig <martin@gnome.org>
1581 * expression.cs (Unary.TryReduceNegative): Added support for
1584 2002-06-08 Martin Baulig <martin@gnome.org>
1586 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
1587 name can't be found in the `defined_names' - the caller will do a
1588 MemberLookup in this case and thus find methods in System.Enum
1589 such as Enum.IsDefined().
1591 2002-06-08 Martin Baulig <martin@gnome.org>
1593 * enum.cs (Enum.ChangeEnumType): This is a custom version of
1594 Convert.ChangeType() which works with TypeBuilder created types.
1595 (Enum.LookupEnumValue, Enum.Define): Use it here.
1597 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
1598 `TypeBuilder.BaseType != null' check.
1599 (TypeContainer.FindMembers): Only lookup parent members if we
1600 actually have a parent.
1601 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
1602 (ConstructorInitializer.Resolve): Likewise.
1604 * interface.cs (Interface.FindMembers): Added
1605 `TypeBuilder.BaseType != null' check.
1607 * rootcontext.cs (RootContext.ResolveCore): Added
1608 "System.Runtime.CompilerServices.IndexerNameAttribute" to
1609 classes_second_stage.
1611 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
1612 debug_type and trace_type when compiling with --nostdlib.
1614 2002-06-07 Martin Baulig <martin@gnome.org>
1616 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
1617 (AddField): Set it to true when adding a non-static field.
1618 (DefineType): Use `have_nonstatic_fields' to find out whether we
1619 have non-static fields, not `Fields != null'.
1621 2002-06-02 Miguel de Icaza <miguel@ximian.com>
1623 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
1624 dereferencing a null on the static-field code path)
1626 2002-05-30 Martin Baulig <martin@gnome.org>
1628 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
1629 to take command line arguments. Use reflection to call the new
1630 custom `Initialize' function on the symbol writer and pass it the
1631 command line arguments.
1633 * driver.cs (--debug-args): New command line argument to pass command
1634 line arguments to the symbol writer.
1636 2002-05-28 Miguel de Icaza <miguel@ximian.com>
1638 * assign.cs (DoResolve): Forgot to do the implicit conversion to
1639 the target type for indexers and properties. Thanks to Joe for
1642 2002-05-27 Miguel de Icaza <miguel@ximian.com>
1644 * typemanager.cs (MethodFlags): returns the method flags
1645 (Obsolete/ShouldIgnore) that control warning emission and whether
1646 the invocation should be made, or ignored.
1648 * expression.cs (Invocation.Emit): Remove previous hack, we should
1649 not do this on matching a base type, we should do this based on an attribute
1651 Only emit calls to System.Diagnostics.Debug and
1652 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
1653 on the command line.
1655 * rootcontext.cs: Global settings for tracing and debugging.
1657 * cs-tokenizer.cs (define): New utility function to track
1658 defines. Set the global settings for TRACE and DEBUG if found.
1660 2002-05-25 Ravi Pratap <ravi@ximian.com>
1662 * interface.cs (Populate*): Pass in the TypeContainer as well as
1663 the DeclSpace as parameters so that we can create EmitContexts and
1664 then use that to apply attributes etc.
1666 (PopulateMethod, PopulateEvent, PopulateProperty)
1667 (PopulateIndexer): Apply attributes everywhere.
1669 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
1672 (ApplyAttributes): Update accordingly.
1674 We now apply interface attributes for all members too.
1676 2002-05-26 Miguel de Icaza <miguel@ximian.com>
1678 * class.cs (Indexer.Define); Correctly check if we are explicit
1679 implementation (instead of checking the Name for a ".", we
1680 directly look up if the InterfaceType was specified).
1682 Delay the creation of the PropertyBuilder.
1684 Only create the PropertyBuilder if we are not an explicit
1685 interface implementation. This means that explicit interface
1686 implementation members do not participate in regular function
1687 lookups, and hence fixes another major ambiguity problem in
1688 overload resolution (that was the visible effect).
1690 (DefineMethod): Return whether we are doing an interface
1693 * typemanager.cs: Temporary hack until we get attributes in
1694 interfaces (Ravi is working on that) and we get IndexerName
1695 support in interfaces.
1697 * interface.cs: Register the indexers as properties.
1699 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
1700 warning, I have verified that this is a bug in the .NET runtime
1701 (JavaScript suffers of the same problem).
1703 * typemanager.cs (MemberLookup): When looking up members for
1704 interfaces, the parent of an interface is the implicit
1705 System.Object (so we succeed in searches of Object methods in an
1706 interface method invocation. Example: IEnumerable x; x.ToString
1709 2002-05-25 Miguel de Icaza <miguel@ximian.com>
1711 * class.cs (Event): Events should also register if they do
1712 implement the methods that an interface requires.
1714 * typemanager.cs (MemberLookup); use the new GetInterfaces
1717 (GetInterfaces): The code used to lookup interfaces for a type is
1718 used in more than one place, factor it here.
1720 * driver.cs: Track the errors at the bottom of the file, we kept
1723 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
1724 instance if the method we are calling is static!
1726 2002-05-24 Miguel de Icaza <miguel@ximian.com>
1728 * attribute.cs (ApplyAttributes): Make this function filter out
1729 the IndexerName attribute (as that attribute in reality is never
1730 applied) and return the string constant for the IndexerName
1733 * class.cs (TypeContainer.Emit): Validate that all the indexers
1734 have the same IndexerName attribute, and if so, set the
1735 DefaultName attribute on the class.
1737 * typemanager.cs: The return value might contain other stuff (not
1738 only methods). For instance, consider a method with an "Item"
1739 property and an Item method.
1741 * class.cs: If there is a problem with the parameter types,
1744 2002-05-24 Ravi Pratap <ravi@ximian.com>
1746 * ecore.cs (ImplicitConversionExists): Wrapper function which also
1747 looks at user defined conversion after making a call to
1748 StandardConversionExists - we need this for overload resolution.
1750 * expression.cs : Update accordingly the various method calls.
1752 This fixes 2 bugs filed against implicit user defined conversions
1754 2002-05-22 Miguel de Icaza <miguel@ximian.com>
1756 * statement.cs: Track the result of the assignment.
1758 2002-05-21 Miguel de Icaza <miguel@ximian.com>
1760 * expression.cs (MemberAccess): Improved error reporting for
1761 inaccessible members.
1763 2002-05-22 Martin Baulig <martin@gnome.org>
1765 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
1766 itself with debugging support.
1768 2002-05-22 Martin Baulig <martin@gnome.org>
1770 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
1771 Removed, this isn't needed anymore.
1773 2002-05-20 Martin Baulig <martin@gnome.org>
1775 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
1776 be underlying type for an enum.
1778 2002-05-20 Miguel de Icaza <miguel@ximian.com>
1780 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
1781 that splits out the loading of just the core types.
1783 * rootcontext.cs (ResolveCore): Split the struct resolution in
1784 two, so we can load the enumeration underlying types before any
1787 * expression.cs (Is): Bandaid until we fix properly Switch (see
1788 bug #24985 for details).
1790 * typemanager.cs (ImplementsInterface): The hashtable will contain
1791 a null if there are no interfaces implemented.
1793 2002-05-18 Miguel de Icaza <miguel@ximian.com>
1795 * cs-parser.jay (indexer_declarator): It is fine to have array
1798 2002-05-17 Miguel de Icaza <miguel@ximian.com>
1800 * typemanager.cs: (RegisterBuilder): New function used to register
1801 TypeBuilders that implement interfaces. Since
1802 TypeBuilder.GetInterfaces (as usual) does not work with lame
1804 (AddUserType): register interfaces.
1806 (ImplementsInterface): Use the builder_to_ifaces hash if we are
1807 dealing with TypeBuilder. Also, arrays are showing up as
1808 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
1809 methods can not be invoked on them!
1811 * ecore.cs (ExplicitReferenceConversionExists): Made public.
1812 (ImplicitReferenceConversionExists): Split out from
1813 StandardConversionExists.
1815 * expression.cs (As): We were only implementing one of the three
1816 cases for the as operator. We now implement them all.
1817 (Is): Implement the various other cases for Is as well.
1819 * typemanager.cs (CACHE): New define used to control if we want or
1820 not the FindMembers cache. Seems to have a negative impact on
1821 performance currently
1823 (MemberLookup): Nested types have full acess to
1824 enclosing type members
1826 Remove code that coped with instance/static returns for events, we
1827 now catch this in RealFindMembers.
1829 (RealFindMembers): only perform static lookup if the instance
1830 lookup did not return a type or an event.
1832 2002-05-17 Miguel de Icaza <miguel@ximian.com>
1834 * assign.cs (CompoundAssign): We pass more semantic information
1835 now to Compound Assignments than we did before: now we have all
1836 the information at hand, and now we resolve the target *before* we
1837 do the expression expansion, which allows the "CacheValue" method
1838 to have the effect we intended (before, a [x] += 1 would generate
1839 two differen ArrayAccess expressions from the ElementAccess,
1840 during the resolution process).
1842 (CompoundAssign.DoResolve): Resolve target and original_source here.
1844 2002-05-16 Miguel de Icaza <miguel@ximian.com>
1846 * expression.cs (ArrayAccess): dropped debugging information.
1848 * typemanager.cs: Small bug fix: I was always returning i_members,
1849 instead of one of i_members or s_members (depending on which had
1852 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
1853 method is invoked before any code generation takes place, and it
1854 is a mechanism to inform that the expression will be invoked more
1855 than once, and that the method should use temporary values to
1856 avoid having side effects
1858 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
1860 * ecore.cs (Expression.CacheTemporaries): Provide empty default
1863 * expression.cs (Indirection, ArrayAccess): Add support for
1864 CacheTemporaries in these two bad boys.
1866 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
1868 (StoreFromPtr): Handle stobj as well.
1870 * expression.cs (UnaryMutator): Share more code.
1872 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
1873 down: I was not tracking the Filter function as well, which
1874 was affecting the results of the cache.
1876 2002-05-15 Miguel de Icaza <miguel@ximian.com>
1878 * attribute.cs: Remove the hack to handle the CharSet property on
1881 2002-05-14 Miguel de Icaza <miguel@ximian.com>
1883 * attribute.cs (DoResolve): More uglyness, we now only try to
1884 resolve the attribute partially, to extract the CharSet
1885 information (only if we are a StructLayout attribute). Otherwise
1887 (GetExtraTypeInfo): Add some code to conditionally kill in the
1888 future this. I am more and more convinced that the .NET
1889 framework has special code to handle the attribute setting on
1892 * expression.cs (IsParamsMethodApplicable): Revert my previous
1893 foreach change here, it was wrong.
1895 2002-05-13 Miguel de Icaza <miguel@ximian.com>
1897 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
1898 (pp_expr): do not abort on unknown input, just return.
1899 (eval): abort if there are pending chars.
1901 * attribute.cs (Attribute.Resolve): Positional parameters are
1902 optional. Deal with that case.
1904 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
1905 the Ansi/Unicode/Auto information for the type.
1907 (TypeContainer.DefineType): instantiate the EmitContext here, as
1908 we will be using it during the type definition (to resolve
1909 attributes) and during the emit phase.
1911 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
1912 to pull type information out of the attributes
1914 (Attribute.Resolve): track the constructor builder, and allow for
1915 multiple invocations (structs and classes will use this).
1917 * ecore.cs (MemberLookupFinal): new version with all the
1918 parameters customizable.
1920 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
1921 constructors. Return if the result value is null (as the error
1922 would have been flagged already by MemberLookupFinal)
1924 Do not allow instances of abstract classes or interfaces to be
1927 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
1928 We have to compare the assembly property here when dealing with
1929 FamANDAssem and Assembly access modifiers, because we might be
1930 creating an assembly from *modules* (that means that we are not
1931 getting TypeBuilders for types defined in other modules that are
1932 part of this assembly).
1934 (Method.Emit): If the method is marked abstract and has a body,
1937 (TypeContainer.DefineMembers): If both the defined member and the
1938 parent name match are methods, then do not emit any warnings: let
1939 the Method.Define routine take care of flagging warnings. But if
1940 there is a mismatch (method overrides something else, or method is
1941 overriwritten by something, then emit warning).
1943 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
1944 set to null, this means `do not check for the return type on the
1947 (Method.Define): set the return type for the method signature to
1948 null, so that we get methods with the same name and parameters and
1949 different return types. This is used to flag warning 114 (you are
1950 hiding a method, and you probably want to use the new/override
1953 * typemanager.cs (MemberLookup): Implemented proper access
1954 control, closing a long standing set of bug reports. The problem
1955 was that the Framework only has two bits: Public and NonPublic,
1956 and NonPublic includes private and protected methods, but we need
1957 to enforce the FamANDAssem, FamOrAssem and Family.
1959 2002-05-11 Miguel de Icaza <miguel@ximian.com>
1961 * statement.cs (GotoCase): Return true: Ammounts to giving up
1962 knowledge on whether we return or not, and letting the other case
1963 be responsible for it.
1965 2002-05-10 Miguel de Icaza <miguel@ximian.com>
1967 * driver.cs: Do not load directories for each file processed, only
1968 do it if there is a pattern.
1970 * ecore.cs: Report readonly assigns here as well, as we might have
1971 been resolved only by MemberAccess.
1973 (SimpleName.SimpleNameResolve): Also be useful for LValue
1974 resolution. We need this to propagate assign to local readonly variables
1976 * typemanager.cs: Use a ptrhashtable for the criteria, because we
1977 do not want to reuse potential criteria memory.
1979 * class.cs (MyEventBuilder): Set reflected_type;
1981 * ecore.cs (Constantify): Added support for constifying bools.
1983 (RootContext.LookupType): Added a cache for values looked up in
1984 the declaration space.
1986 * typemanager.cs (FindMembers): Now is a front-end to
1987 RealFindMembers, and provides a two-level hashtable-based cache to
1990 15% performance improvement: from 22.5 to 19.2 seconds.
1992 * expression.cs (IsParamsMethodApplicable): use foreach.
1993 (Invocation.DoResolve): ditto.
1994 (New.DoResolve): ditto.
1995 (ArrayCreation.DoResolve): ditto.
1997 * ecore.cs (FindMostEncompassingType): use foreach.
1999 * delegate.cs (NewDelegate.DoResolve): Use foreach
2001 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
2002 (RemoveMethods): use foreach.
2004 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
2005 nested foreach statements instead of for, and also break out of
2006 the inner loop once a match is found.
2008 (Invocation.OverloadResolve): Use foreach, simplify the code.
2010 2002-05-08 Miguel de Icaza <miguel@ximian.com>
2012 * cfold.cs (BinaryFold): During an enumeration evaluation context,
2013 we actually unwrap the expression to allow for extra information
2016 * expression.cs: Use Shr_Un on unsigned operations.
2018 2002-05-08 Ravi Pratap <ravi@ximian.com>
2020 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
2021 applicable operators was not being considered correctly. This closes
2022 the bug Miguel reported.
2024 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
2026 * attribute.cs: check that the type derives from System.Attribute
2027 and report the correct error in that case (moved the duplicate code to
2028 its own method, too).
2030 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
2032 * attribute.cs: lookup attribute type name as the spec says: first the
2033 bare attribute name and then name + "Attribute" (nant compiles with
2034 mcs after this fix).
2036 2002-05-07 Miguel de Icaza <miguel@ximian.com>
2038 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
2039 Because of the way we parse things, we should try to see if a
2040 UIntConstant can fit in an integer.
2042 2002-05-07 Ravi Pratap <ravi@ximian.com>
2044 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
2045 when we are in an explicit context.
2047 (ConvertReferenceExplicit): When converting from Iface type S to Class
2048 T make sure the rules are implemented as an OR.
2050 * parameter.cs (ParameterType): Make it a property for now although the
2051 purpose really isn't anything immediate.
2053 * expression.cs (Is*Applicable): Do better checking on the parameter type
2054 of a ref/out parameter. The ones from the system assemblies are already
2055 marked with the correct type so we don't need to do any correction.
2057 * ecore.cs (StandardConversionExists): Conversion from Interface types to
2058 the object type is standard too so include that.
2060 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2062 * ecore.cs (StandardConversionExists): Augment with missing code:
2063 deal with IntConstant, LongConstants and Enumerations.
2065 * assign.cs: Report the error, instead of failing silently
2067 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
2068 typecontainer that they are declared, because the
2069 typecontainer/namespace will have the list of using clauses that
2072 Assembly Attributes were escaping the normal registration
2075 (EmitCode): Apply attributes within an EmitContext that represents
2076 the container they were declared on.
2078 * cs-parser.jay: Track bases for structs. How did I get this wrong?
2080 2002-05-06 Ravi Pratap <ravi@ximian.com>
2082 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
2083 Revamp completely - make much cleaner as we now operate only
2086 (FindMostSpecificSource, FindMostSpecificTarget): New methods
2087 to implement the logic detailed in the spec more correctly.
2089 (UserDefinedConversion): Update accordingly.
2091 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2093 * statement.cs: Return flow analysis information up.
2095 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
2098 (token): Do not consume an extra character before calling
2101 2002-05-06 Piers Haken <piersh@friskit.com>
2103 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
2105 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2107 * class.cs (Constructor.Emit): Set the IsStatic flag in the
2108 EmitContext during the instance constructor initializer
2109 resolution, to stop access to instance variables.
2111 This is mandated by the spec, last paragraph of the `constructor
2112 initializers' section.
2114 2002-05-05 Miguel de Icaza <miguel@ximian.com>
2116 * cs-parser.jay, class.cs (Accessor): new class used to represent
2117 an accessor (get or set). In the past we used `null' to represent
2118 a missing accessor. But this is ambiguous because there was no
2119 way to tell in abstract indexers/properties if one of them was
2122 Now there is a way of addressing that.
2124 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
2125 instead of FindMembers.
2127 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
2128 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
2130 * attribute.cs: Treat indexers and properties as the same in terms
2131 of applying attributes
2133 * ecore.cs (FindMostEncompassedType): Use statically initialized
2134 EmptyExpressions()s like we do elsewhere to avoid creating useless
2135 objects (and we take this out of the tight loop).
2137 (GetConversionOperators): Move the code to extract the actual
2138 operators to a separate routine to clean things up.
2140 2002-05-04 Miguel de Icaza <miguel@ximian.com>
2142 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
2143 events are always registered FieldBuilders.
2145 * class.cs (FieldBase): New class shared by Fields
2147 * delegate.cs: If we are a toplevel delegate, use our full name.
2148 If we are a nested delegate, then only use our tail name.
2150 2002-05-02 Ravi Pratap <ravi@ximian.com>
2152 * expression.cs (IsApplicable): Ensure that we add the "&" to
2153 ref/out types before comparing it with the type of the argument.
2155 (IsParamsMethodApplicable): Ditto.
2157 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
2160 * delegate.cs : Handle the case when we have more than one applicable
2161 method. Flag an error only when we finish checking all.
2163 2002-05-02 Miguel de Icaza <miguel@ximian.com>
2165 * expression.cs: Add support for boolean static initializers.
2167 2002-05-01 Miguel de Icaza <miguel@ximian.com>
2169 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
2171 * parameter.cs (ComputeParameterTypes,
2172 ComputeAndDefineParameterTypes): Better error handling: now we
2173 clear the `types' cache if we fail during any of the type lookups.
2174 We also return the status code correctly to our caller
2176 * delegate.cs: If we fail to define a delegate, abort the extra
2179 * expression.cs (Binary.ResolveOperator): for
2180 operator==(object,object) and operator !=(object, object) we also
2181 have to verify that there is an implicit conversion from one to
2184 (ArrayAccess.DoResolve): Array Access can operate on
2187 2002-04-30 Miguel de Icaza <miguel@ximian.com>
2189 * assign.cs (CompoundAssign): A new class used as a "flag" that
2190 the assignment actually is happening as part of a compound
2191 assignment operator.
2193 During compound assignment, a few new rules exist to enable things
2200 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
2201 to the type of x) if y is implicitly convertible to the type of x,
2202 and the operator is a builtin operator and the return type of the
2203 operator is explicitly convertible to the type of x.
2205 * rootcontext.cs: Reset warning level to 2. 4 catches various
2206 "interesting" features in mcs, we must clean this up at some
2207 point, but currently am trying to kill other bugs ;-)
2209 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
2210 in container classes as well.
2212 * expression.cs (Binary.ResolveOperator): Handle string case
2213 before anything else (as operator overloading does emit an error
2214 before doing anything else).
2216 This code could go away when we move to a table driven model, but
2217 i could not come up with a good plan last night.
2219 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
2221 * typemanager.cs (CSharpName): reimplementation using regex.
2222 * class.cs: added null check for fields in Emit
2223 * rootcontext.cs: set warninglevel to 4
2225 2002-04-29 Miguel de Icaza <miguel@ximian.com>
2227 * typemanager.cs (CSharpName): reimplemented with Lupus
2230 2002-04-28 Miguel de Icaza <miguel@ximian.com>
2232 * statement.cs (If): correclty implement Resolve, because we were
2233 not catching sem errors in there. The same process is needed
2235 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
2238 (Statement.Warning_DeadCodeFound): Factorize code.
2239 (While): Report dead code here too.
2241 (Statement): Added Resolve virtual method to allow
2242 for resolution split from the emit code.
2244 2002-04-26 Miguel de Icaza <miguel@ximian.com>
2246 * statement.cs (EmitBoolExpression): No longer try to resolve the
2248 (MakeBoolean): New utility function that resolve, implicitly
2249 converts to boolean and tags the expression.
2252 (If, Do): Implement dead code elimination.
2253 (While): Implement loop inversion
2255 (Do, While, For, If): Resolve the expression prior to calling our
2258 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
2261 - added method Report28 (warning: program has more than one entry point)
2262 - added method IsEntryPoint, implements paragraph 10.1 of the spec
2263 - modified method Method.Define, the part at the end of the method
2265 * rootcontext.cs: added static public Location EntryPointLocation;
2267 * ../errors/cs0028.cs : Add test case for the above warning.
2270 - modified method CSharpName to allow arrays of primitive type to
2271 be printed nicely (e.g. instead of System.Int32[][] it now prints
2273 - added method CSharpSignature: returns the signature of a method
2274 in string format to be used in reporting errors, warnings, etc.
2276 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
2279 2002-04-26 Ravi Pratap <ravi@ximian.com>
2281 * delegate.cs (Define): Fix extremely silly bug where I was
2282 setting the type of the 'object' parameter of the BeginInvoke
2283 method to System.IAsyncResult instead of System.Object ;-)
2285 2002-04-26 Miguel de Icaza <miguel@ximian.com>
2287 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
2290 (Constructor.Emit): return if we fail to initialize the
2291 constructor. Another door closed!
2293 * expression.cs (New.DoResolve): Improve error message (from -6 to
2294 1501). Use DeclaredOnly lookup to find the exact constructor.
2296 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
2297 loop. This is useful.
2299 * cs-parser.jay: Adjust the default parameters so that destructors
2300 have the proper signature.
2302 2002-04-26 Martin Baulig <martin@gnome.org>
2304 * driver.cs (LoadAssembly): If `assembly' contains any characters
2305 which are only valid in path names and not in assembly names
2306 (currently slash, backslash and point), use Assembly.LoadFrom ()
2307 instead of Assembly.Load () on the `assembly' (before iteration
2308 over the link_paths).
2310 2002-04-26 Martin Baulig <martin@gnome.org>
2312 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
2314 2002-04-25 Miguel de Icaza <miguel@ximian.com>
2316 * class.cs (Property): use the new typemanager.MemberLookup
2318 (TypeContainer.MemberLookup): Implement using the
2319 TypeManager.MemberLookup now.
2321 * typemanager.cs: Make MemberLookup a function of the TypeManager,
2322 and return MemberInfos, so that these can be used without an
2323 EmitContext (what we had before).
2325 2002-04-24 Miguel de Icaza <miguel@ximian.com>
2327 * expression.cs: Fix the case where the argument to params if the
2328 type of the params. I omitted handling this before. Fixed
2330 2002-04-22 Miguel de Icaza <miguel@ximian.com>
2332 * driver.cs: Call BootCorlib_PopulateCoreType
2334 * class.cs (Property.CheckBase): Check for properties only, not
2337 * interface.cs: Temporary hack: try/catch around the
2338 CustomAttributeBuilder, because I am getting an exception that I
2341 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
2342 types whose definitions are required to be there (attributes are
2343 defined before standard types).
2345 Compute definitions as we boot the various types, as they are used
2346 immediately (value_type class will need object_type, but if we do
2347 not initialize object_type, we will pass a null, which will let
2348 the runtime pick the System.Object from the existing corlib, which
2349 is not what we want).
2351 2002-04-22 Patrik Torstensson <totte@labs2.com>
2353 * cs-tokenizer.cs: fixed a number of trim() issues.
2355 2002-04-22 Ravi Pratap <ravi@ximian.com>
2357 * expression.cs (Argument.Type): Ensure that we return the correct
2358 type when we have out or ref parameters [in which case we
2361 2002-04-22 Miguel de Icaza <miguel@ximian.com>
2363 * class.cs (Property, Indexer): Allow extern modifier in there.
2365 * typemanager.cs (InitBaseTypes): Initializes object_type and
2366 value_type, since those will be used early on during the bootstrap
2367 process to compile corlib.
2369 (InitCoreTypes): Move code from here to InitBaseTypes.
2371 2002-04-21 Miguel de Icaza <miguel@ximian.com>
2373 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
2374 single-dimension arrays as using the ldlen opcode.
2376 Daniel Lewis discovered this optimization.
2378 * typemanager.cs: Add signature for System.Array::get_Length
2380 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2382 * statement.cs: report the error when the foreach does not apply to an
2383 array nor a collection.
2385 2002-04-19 Miguel de Icaza <miguel@ximian.com>
2387 * expression.cs: Add implicit conversions to the operator ~.
2389 * constant.cs (DecimalConstant.Emit): Emit decimal value.
2391 * typemanager.cs: Locate the decimal constructor.
2393 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2395 * attribute.cs: use the new property of TypeOf.
2396 * expression.cs: added 'get' property around typearg.
2398 These changes fix a build breaker reported by NickD. Is this the
2399 correct way to fix? If not, please, revert my changes and make it
2402 2002-04-17 Miguel de Icaza <miguel@ximian.com>
2404 * attribute.cs: Add support for typeof in attribute invocations.
2405 I am not sure that this is right though.
2407 2002-04-14 Duncan Mak <duncan@ximian.com>
2409 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
2410 Binary.Operator.Division case.
2412 2002-04-13 Ravi Pratap <ravi@ximian.com>
2414 * class.cs (DefineType): Ensure that we do a proper check on
2415 attribute types and also register it with the TypeManager.
2417 (TypeContainer.Targets): The default for attribute types is
2418 AttributeTargets.All.
2420 * attribute.cs (ApplyAttributes): Registering the attribute type
2421 is done elsewhere, not when we discover we have a Usage attribute.
2423 2002-04-12 Ravi Pratap <ravi@ximian.com>
2425 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
2426 and get rid of is_delegate parameter.
2428 * everywhere : update.
2430 2002-04-12 Ravi Pratap <ravi@ximian.com>
2432 * cs-parser.jay (compilation_unit): Revamp completely to use
2433 some new ideas that I got from Rhys' grammar to solve the problems
2434 with assembly level attributes.
2436 (outer_declaration): New grammar production.
2438 (attribute_sections): Add.
2440 (opt_attributes): Base on attribute_sections
2442 (namespace_declaration): Allow opt_attributes to tackle the case
2443 when we have assembly level attributes - we are clever in this
2446 * attribute.cs (ApplyAttributes): Do not worry about assembly
2447 attributes in the non-global context.
2449 * rootcontext.cs (AddGlobalAttributes): Go back to using this
2450 instead of SetGlobalAttributes.
2452 * class.cs, rootcontext.cs : Ensure we define and generate
2453 attribute types before anything else.
2455 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
2456 and flag the new error -20 for the case when the attribute type
2457 does not have valid targets specified. csc does not catch this.
2459 * ../errors/errors.txt : update for error # -20
2461 2002-04-11 Ravi Pratap <ravi@ximian.com>
2463 * support.cs (InternalParameters.ParameterModifier): Do some null
2464 checking and return sane values.
2466 * class.cs (Method.Define): If we are a PInvoke method, ensure
2467 that we are static and extern. Report error # 601
2469 * ../errors/cs0601.cs : Add test case for the above error.
2471 2002-04-07 Ravi Pratap <ravi@ximian.com>
2473 * rootcontext.cs (attribute_types): We need to keep type of
2474 all attribute types separately and emit code for them first.
2476 (RegisterAttribute) : Implement.
2478 * class.cs (DefineType): Check if the current Type is a custom
2479 attribute type and register it accordingly.
2481 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
2482 adding the first attribute twice and rename to
2484 (SetGlobalAttributes): this.
2486 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
2489 * attribute.cs (ApplyAttributes): Take an additional argument telling us
2490 if we are processing global arguments. Hmm, I am unsure of this.
2492 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2494 * expression.cs: added static array of strings to avoid calling
2495 Enum.ToString () for Operator in Binary. Significant recover of
2498 2002-04-10 Miguel de Icaza <miguel@ximian.com>
2500 * class.cs (FindMembers): Allow the Builders of the various
2501 members to be null. If they are skip them. This only happens
2502 during the PInvoke declaration.
2504 2002-04-09 Miguel de Icaza <miguel@ximian.com>
2506 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
2507 failure, so we do not keep going afterwards.
2509 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
2510 wanted to pass `false' as the `is_delegate' argument. If this is
2511 the case, why not use delegate_type == null to mean `is_delegate =
2512 false' and anything else as is_delegate = true.
2514 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
2516 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
2517 code for the section, not the beginning of the tests.
2519 2002-04-08 Miguel de Icaza <miguel@ximian.com>
2521 * cfold.cs: Handle operator + (Enum x, Underlying x)
2523 * expression.cs (Binary): same. Warn about errors where we have
2524 Enum/Enum in operator + as well.
2526 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
2529 - added support for switch(bool)
2530 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
2531 - add TableSwitchEmit() to handle table-based switch statements
2533 2002-04-05 Ravi Pratap <ravi@ximian.com>
2535 * expression.cs (Invocation.OverloadResolve): Factor out code which
2536 does parameter compatibility checking with arguments so that we can
2537 re-use the code even from Delegate.VerifyApplicability
2539 (VerifyArgumentsCompat): Move above code here.
2541 * delegate.cs (VerifyApplicability): Get rid of duplicate code
2542 and instead make a call to the above method.
2544 2002-03-31 Ravi Pratap <ravi@ximian.com>
2546 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
2547 We use it to keep track of classes which are attribute types.
2549 2002-04-02 Miguel de Icaza <miguel@ximian.com>
2551 * delegate.cs (Delegate.Define): Correctly define the types in the
2552 presence of fixed and array parameters.
2554 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
2557 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
2558 include NonPublic after the first iteration.
2560 * class.cs (Indexer.CheckBase): Only check if both parents are
2563 * cs-parser.jay (accessor_body): If empty, set to null.
2565 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
2566 same code path here to resolve constants names that we did have in
2567 MemberAccess.DoResolve. There is too much code duplicated here.
2569 2002-04-01 Miguel de Icaza <miguel@ximian.com>
2571 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
2573 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
2576 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
2577 tokens, numbers and strings.
2579 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
2582 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
2583 asyncronous parameters and the regular parameters.
2585 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
2586 specify the target directory.
2588 * expression.cs: (This.DoResolve): Simplify
2589 (As.Emit): Optimize, do not generate IsInst if the expression is
2590 always of the given type.
2592 (Is.DoResolve): Bug fix, we were reporting both always/never for
2595 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
2596 creating too many unnecessary arrays.
2598 2002-03-31 Miguel de Icaza <miguel@ximian.com>
2600 * class.cs (EmitFieldInitializer): Use Assign expression to assign
2601 fields instead of rolling our own initializer. Takes care of all
2602 implicit conversions, and drops unnecessary static checks/argument.
2604 2002-03-31 Dick Porter <dick@ximian.com>
2606 * driver.cs: use the GetDirectories() return values properly, and
2607 use "/" as path separator.
2609 2002-03-30 Miguel de Icaza <miguel@ximian.com>
2611 * expression.cs (Unary): Optimize - - expr into expr.
2612 (Binary): Optimize a + (-b) into a -b.
2614 * codegen.cs (CodeGen): Made all methods static.
2616 2002-03-29 Miguel de Icaza <miguel@ximian.com>
2620 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
2621 TypeBuilder property.
2623 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
2626 * tree.cs: Removed the various RecordXXXX, and replaced with a
2627 single RecordDecl. Removed all the accessor methods, and just
2628 left a single access point Type
2630 * enum.cs: Rename DefineEnum to DefineType.
2632 * decl.cs: New abstract method `DefineType' used to unify the
2633 Defines for Enumerations, Interfaces, TypeContainers and
2636 (FindType): Moved LookupInterfaceOrClass here. Moved the
2637 LookupBaseClasses method that used to live in class.cs and
2638 interface.cs here, and renamed to FindType.
2640 * delegate.cs: Implement DefineType. Take advantage of the
2641 refactored pattern for locating the parent builder without taking
2642 the parent_builder argument (which we know does not work if we are
2643 nested, and triggering a toplevel definition).
2645 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2647 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
2648 accessibility of a member has changed during override and report
2651 * class.cs (Method.Define, Property.Define): Only complain on
2652 overrides if the method is private, any other accessibility is
2653 fine (and since we just checked the permission is the same, we are
2656 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
2657 and elif are processed always. The other pre-processing
2658 directives are only processed if we are "taking" the path
2660 2002-03-29 Martin Baulig <martin@gnome.org>
2662 * class.cs (Method.Emit): Only emit symbolic debugging info if the
2663 current location is not Null.
2665 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
2666 a separate method so we can profile it.
2668 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
2669 `span.Seconds' are just seconds, but no minutes or hours.
2670 (MainDriver): Profile the CodeGen.SaveSymbols calls.
2672 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2674 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
2675 Remove the gratuitous set of Final:
2677 // If an interface implementation, then we can set Final.
2678 if (((flags & MethodAttributes.Abstract) == 0) &&
2679 implementing.DeclaringType.IsInterface)
2680 flags |= MethodAttributes.Final;
2682 I do not know what I was smoking when I used that.
2685 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
2686 step into fixing the name resolution issues for delegates and
2687 unifying the toplevel name resolution.
2689 2002-03-28 Martin Baulig <martin@gnome.org>
2691 * class.cs (Method.Emit): If we have a symbol writer, call its
2692 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
2693 tell it about the current method.
2695 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
2696 writer that we're going to emit the first byte of IL code for a new
2697 statement (a new source line).
2698 (EmitContext.EmitTopBlock): If we have a symbol writer, call
2699 EmitContext.Mark() before emitting any code.
2701 * location.cs (SymbolDocument): Return null when we're Null.
2703 * statement.cs (Statement): Moved the `Location loc' variable here.
2704 (Statement.EmitBoolExpression): If we have a symbol writer, call
2705 ec.Mark() before emitting any code to tell it that we're at the
2706 beginning of a new statement.
2707 (StatementExpression): Added `Location' argument to the constructor.
2708 (Block): Added public readonly variable `StartLocation' and public
2709 variable `EndLocation'. The latter is to be set using SetEndLocation().
2710 (Block): Added constructor which takes a start and end location.
2711 (Block.SetEndLocation): New method. This sets the end location.
2712 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
2713 local variables we create.
2714 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
2715 each statement and do also mark the begin and end of the block.
2717 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
2718 tell it the current lexer.Location, use Location.Null for the end of the
2720 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
2721 current block, set its end location using SetEndLocation().
2722 (statement_expression): StatementExpression constructor now takes the
2723 lexer.Location as additional argument.
2724 (for_statement, declare_local_variables): Likewise.
2725 (declare_local_variables): When creating a new implicit block, use the
2726 new Block constructor and pass it the lexer.Location.
2728 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2730 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
2731 members also on the parent interfaces recursively.
2733 2002-03-27 Miguel de Icaza <miguel@ximian.com>
2735 * report.cs: Use new formats, since Gonzalo finished the missing
2738 * expression.cs (Binary.ResolveOperator): added missing operator|
2739 operator& and operator^ for bool/bool.
2741 * cs-parser.jay: CheckDef now takes a Location argument that is
2742 used to report errors more precisly (instead of reporting the end
2743 of a definition, we try to track something which is a lot closer
2744 to the source of the problem).
2746 * cs-tokenizer.cs: Track global token use, so we can properly flag
2747 the use of #define/#undef after the first token has been seen.
2749 Also, rename the reportXXXX to Error_DescriptiveName
2751 * decl.cs (DeclSpace.IsTopLevel): Move property here from
2752 TypeContainer, so that Enum and Interface can use this too.
2754 * class.cs (TypeContainer.LookupInterfaceOrClass,
2755 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
2756 `builder' argument. Typically this was used to pass the parent
2757 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
2760 The problem is that a nested class could trigger the definition of
2761 a toplevel class, and the builder would be obviously wrong in that
2764 So we drop this argument, and we compute dynamically the
2765 TypeBuilder/ModuleBuilder (the correct information was available
2766 to us anyways from DeclSpace.Parent)
2768 * interface.cs (Interface.DefineInterface): Drop builder
2769 parameter cleanup like class.cs
2771 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
2774 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
2777 (Try.Emit): Propagate the returns value from the statement.
2779 (Return.Emit): Even if we are leavning
2781 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
2783 * modifiers.cs: Fix the computation of MethodAttributes flags.
2785 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
2787 * driver.cs: allow compilation of files that start with '/'.
2788 Add a default case when checking the argument of --target.
2790 2002-03-25 Miguel de Icaza <miguel@ximian.com>
2792 * interface.cs: Implement the same search algorithm for types in
2795 * delegate.cs: Do not allow multiple definition.
2797 * Recovered ChangeLog that got accidentally amputated
2799 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
2801 * rootcontext.cs: Load manually enum to allow core classes to
2802 contain enumerations.
2804 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
2805 Update to new static methods in TypeManager.
2807 * typemanager.cs (GetMethod, GetConstructor): Use our
2808 implementation of FindMembers to find the members, since during
2809 corlib compilation, the types are TypeBuilders and GetMethod and
2810 GetConstructor do not work.
2812 Make all methods in TypeManager static.
2814 (InitCodeHelpers): Split the functionality from
2815 the InitCodeTypes function.
2817 * driver.cs: Call InitCodeHelpers after we have populated the
2820 * cs-parser.jay (delegate_declaration): we did not used to compute
2821 the delegate name correctly for void delegates.
2823 2002-03-24 Miguel de Icaza <miguel@ximian.com>
2825 * rootcontext.cs (RootContext): Init the interface_resolve_order
2826 and type_container_resolve_order always.
2828 (ResolveCore, BootstrapCorlib_ResolveClass,
2829 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
2830 compiler when compiling with --nostdlib
2832 * class.cs (TypeContainer.DefineType): Check that our parent is
2833 not null. This test is most important when we are bootstraping
2836 * codegen.cs: Split out the symbol writing code.
2838 2002-03-25 Martin Baulig <martin@gnome.org>
2840 * driver.cs (-g): Made -g an alias for --debug.
2842 2002-03-24 Martin Baulig <martin@gnome.org>
2844 * codegen.cs (SymbolWriter): New public variable. Returns the
2845 current symbol writer.
2846 (CodeGen): Added `bool want_debugging_support' argument to the
2847 constructor. If true, tell the ModuleBuild that we want debugging
2848 support and ask it for the ISymbolWriter.
2849 (Save): If we have a symbol writer, call it's Close() method after
2850 saving the assembly.
2852 * driver.c (--debug): New command line argument to create a
2853 debugger information file.
2855 * location.cs (SymbolDocument): New public property. Returns an
2856 ISymbolDocumentWriter object for the current source file or null
2857 if we don't have a symbol writer.
2859 2002-03-21 Miguel de Icaza <miguel@ximian.com>
2861 * driver.cs (LoadAssembly): Correctly return when all the paths
2862 have been tried and not before.
2864 * statement.cs (Switch.Emit): return the actual coverage for this
2865 statement (returns/not-returns)
2867 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
2868 switch of the statement if we are the last switch section. That
2869 kills two problems: try/catch problems (we used to emit an empty
2870 nop at the end) and switch statements where all branches would
2873 2002-03-19 Miguel de Icaza <miguel@ximian.com>
2875 * driver.cs: Add default assemblies (the equivalent to the
2876 Microsoft CSC.RSP file)
2878 * cs-tokenizer.cs: When updating `cols and setting it to zero,
2879 also update tokens_seen and set it to false.
2881 * driver.cs: Implement --recurse for Mike.
2883 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
2884 correctly splitting out the paths.
2886 2002-03-18 Miguel de Icaza <miguel@ximian.com>
2888 * interface.cs (Interface.PopulateProperty): Instead of using
2889 `parent' as the declaration space for the set parameters, use
2892 * support.cs (InternalParameters): InternalParameters constructor
2893 takes a DeclSpace instead of a TypeContainer.
2895 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
2896 types are being initialized, load the address of it before calling
2899 (New): Provide a mechanism to disable the generation of local
2900 value type temporaries when the caller will be providing us with
2901 an address to store it.
2903 (ArrayCreation.EmitDynamicInitializers): Use it.
2905 2002-03-17 Miguel de Icaza <miguel@ximian.com>
2907 * expression.cs (Invocation.EmitArguments): Only probe for array
2908 property if there is more than one argument. Sorry about that.
2910 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
2913 * class.cs (Method.LabelParameters): Fix incorrect code path that
2914 prevented the `ParamArrayAttribute' from being applied to the
2917 2002-03-16 Miguel de Icaza <miguel@ximian.com>
2919 * support.cs (ReflectionParameters): Correctly compute whether the
2920 last argument is a params array. Fixes the problem with
2923 * typemanager.cs: Make the assemblies array always be non-null
2924 (empty, but non-null)
2926 * tree.cs (RecordDecl): New function that abstracts the recording
2927 of names. This reports error 101, and provides a pointer to the
2928 previous declaration. Fixes a crash in the compiler.
2930 * cs-parser.jay (constructor_declaration): Update to new grammar,
2931 and provide a constructor_body that can be empty.
2933 2002-03-15 Miguel de Icaza <miguel@ximian.com>
2935 * driver.cs: Add support for --resources.
2937 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
2938 Make all types for the various array helper methods be integer.
2940 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
2941 CheckState to ConvCast.
2943 (ConvCast): Now it takes a `checked' state argument, to avoid
2944 depending on the emit context for the conversion, and just using
2945 the resolve time setting.
2947 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
2948 instead of Invocation.EmitArguments. We do not emit the original
2949 arguments, instead we emit those which have been converted to
2950 unsigned int expressions.
2952 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
2954 * codegen.cs: ditto.
2956 * expression.cs (LocalVariableReference): Drop the use of the
2957 Store function that depended on the variable index.
2959 * statement.cs (VariableInfo): Drop the `Idx' property from this
2960 class, as this is not taking into account the indexes for
2961 temporaries tat we generate during the execution, getting the
2964 * class.cs: First emit class initializers, then call the parent
2967 * expression.cs (Binary): Fix opcode emision.
2968 (UnaryMutator.EmitCode): Support checked code generation
2970 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
2971 matches for events for both the Static and Instance scans,
2972 pointing to the same element. Fix that.
2974 2002-03-14 Miguel de Icaza <miguel@ximian.com>
2976 * rootcontext.cs (ResolveTree): Always set the
2977 interface_resolve_order, because nested interfaces will be calling
2980 * class.cs (GetInterfaceOrClass): Track the same resolution
2981 process used by TypeManager.LookupType. This fixes the nested
2982 type lookups in class declarations (separate path from
2985 (TypeContainer.DefineType): Also define nested interfaces.
2986 (TypeContainer.RegisterOrder): New public function used to
2987 register the order in which child interfaces need to be closed.
2989 Nested interfaces need to be closed after their parents have been
2992 * interface.cs (InterfaceAttr): Put all the logic for computing
2993 the interface attribute here.
2995 (DefineInterface): Register our interface order with the
2996 RootContext or with the TypeContainer depending on the case.
2998 2002-03-12 Miguel de Icaza <miguel@ximian.com>
3000 * cs-parser.jay: rework foreach statement to work with the new
3001 changes to the policy on SimpleNames.
3003 * report.cs: support Stacktrace on warnings as well.
3005 * makefile: drop --unsafe and /unsafe from the compile.
3007 2002-03-13 Ravi Pratap <ravi@ximian.com>
3009 * ecore.cs (StandardConversionExists): Modify to take an Expression
3010 as the first parameter. Ensure we do null -> reference type conversion
3013 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
3014 temporary Expression objects.
3016 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
3018 * interface.cs: workaround bug in method overloading resolution
3019 (there is already a bugzilla bug for it).
3021 2002-03-12 Miguel de Icaza <miguel@ximian.com>
3023 We could also solve this problem by having a separate path for
3024 performing type lookups, instead of DoResolve, we could have a
3025 ResolveType entry point, and only participating pieces of the
3026 production (simplename, deref, array) would implement this.
3028 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
3029 signal SimpleName to only resolve type names and not attempt to
3030 resolve anything else.
3032 * expression.cs (Cast): Set the flag.
3034 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
3036 * class.cs: Only report 108 if there is no `new' modifier.
3038 * cs-parser.jay: rework foreach statement to work with the new
3039 changes to the policy on SimpleNames.
3041 * report.cs: support Stacktrace on warnings as well.
3043 * makefile: drop --unsafe and /unsafe from the compile.
3045 2002-03-11 Miguel de Icaza <miguel@ximian.com>
3047 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
3048 lookups here, instead of doing that at parse time. This means
3049 that our grammar will not introduce `LocalVariableReferences' as
3050 expressions at this point. That solves the problem of code like
3058 This is only half the fix. The full fix requires parameters to
3059 also be handled in this way.
3061 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
3062 makes the use more obvious of the DeclSpace. The
3063 ec.TypeContainer.TypeBuilder is now only used to pull the
3066 My theory is that I can get rid of the TypeBuilder completely from
3067 the EmitContext, and have typecasts where it is used (from
3068 DeclSpace to where it matters).
3070 The only pending problem is that the code that implements Aliases
3071 is on TypeContainer, and probably should go in DeclSpace.
3073 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
3074 lookups here, instead of doing that at parse time. This means
3075 that our grammar will not introduce `LocalVariableReferences' as
3076 expressions at this point. That solves the problem of code like
3084 This is only half the fix. The full fix requires parameters to
3085 also be handled in this way.
3087 * class.cs (Property.DefineMethod): When implementing an interface
3088 method, set newslot, when implementing an abstract method, do not
3089 set the flag (before we tried never setting it, or always setting
3090 it, which is the difference).
3091 (Indexer.DefineMethod): same.
3092 (Method.DefineMethod): same.
3094 * ecore.cs: Only set the status used flag if we get back a Field.
3096 * attribute.cs: Temporary hack, so Paolo can keep working.
3098 2002-03-08 Ravi Pratap <ravi@ximian.com>
3100 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
3101 the unmanaged type in the case we have a MarshalAs attribute.
3103 (Resolve): Handle the case when we are parsing the special MarshalAs
3104 attribute [we need to store the unmanaged type to use later]
3106 * typemanager.cs (marshal_as_attr_type): Built in type for the
3107 MarshalAs Attribute.
3109 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
3110 on parameters and accordingly set the marshalling info.
3112 2002-03-09 Miguel de Icaza <miguel@ximian.com>
3114 * class.cs: Optimizing slightly by removing redundant code after
3115 we switched to the `NoTypes' return value.
3116 (Property.DefineMethod): use NoTypes here too.
3118 This fixes the bug I introduced in my last batch of changes.
3120 2002-03-05 Ravi Pratap <ravi@ximian.com>
3122 * tree.cs (RecordEnum): Add. We now keep track of enums too.
3124 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
3125 Enums since those are types too.
3127 * cs-parser.jay (enum_declaration): Record enums as we parse them.
3129 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
3130 thanks to a call during the lookup process.
3132 2002-03-07 Miguel de Icaza <miguel@ximian.com>
3134 * statement.cs (Foreach): Lots of work to accomodate a particular
3135 kind of foreach statement that I had not kept in mind. It is
3136 possible to have foreachs on classes that provide a GetEnumerator
3137 method that return objects that implement the "pattern" for using
3138 a foreach, there is no need to support GetEnumerator
3141 This is needed to compile nant.
3143 * decl.cs: Only report 114 if the member is not `Finalize' and if
3144 the warning level is at least 2.
3146 * class.cs: Moved the compare function from Method to
3149 (MethodSignature.InheritableMemberSignatureCompare): Add new
3150 filter function that is used to extract inheritable methods from a
3153 (Method.Define): Use the new `inheritable_method_signature_filter'
3156 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
3159 2002-03-06 Miguel de Icaza <miguel@ximian.com>
3161 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
3163 * cs-parser.jay: Add opt_semicolon to the interface declaration.
3165 * expression.cs: Pass location information to
3166 ConvertImplicitStandard.
3168 * class.cs: Added debugging code to track return values from
3171 2002-03-05 Miguel de Icaza <miguel@ximian.com>
3173 * expression.cs (Is.DoResolve): If either side of the `is' is an
3174 interface, do not flag the warning.
3176 * ecore.cs (ImplicitReferenceConversion): We need a separate test
3179 * report.cs: Allow for --fatal to be used with --probe.
3181 * typemanager.cs (NoTypes): Move the definition for the empty Type
3184 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
3186 (TypeContainer.DefineProxy): New function used to proxy to parent
3187 implementations when implementing interfaces.
3188 (TypeContainer.ParentImplements): used to lookup if our parent
3189 implements a public function that is required by an interface.
3190 (TypeContainer.VerifyPendingMethods): Hook this up.
3192 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
3193 `modules' and `assemblies' arraylists into arrays. We only grow
3194 these are the very early start up of the program, so this improves
3195 the speedof LookupType (nicely measured).
3197 * expression.cs (MakeByteBlob): Replaced unsafe code with
3198 BitConverter, as suggested by Paolo.
3200 * cfold.cs (ConstantFold.Binary): Special case: perform constant
3201 folding of string concatenation, but if either side is a string,
3202 and the other is not, then return null, and let the runtime use
3203 the concatenation on the string plus the object (using
3206 2002-03-04 Miguel de Icaza <miguel@ximian.com>
3208 Constant Folding has been implemented now.
3210 * expression.cs (Unary.Reduce): Do not throw an exception, catch
3211 the error instead on types that are not supported in one's
3214 * constant.cs (Constant and all children): New set of functions to
3215 perform implict and explicit conversions.
3217 * ecore.cs (EnumConstant): Implement the new functions to perform
3218 conversion by proxying to the child expression.
3220 * codegen.cs: (ConstantCheckState): Constant evaluation has its
3221 own separate setting that can not be turned off from the command
3222 line using --unchecked or --checked and is only controlled using
3223 the checked/unchecked statements and expressions. This setting is
3224 used by the constant folder to flag errors.
3226 * expression.cs (CheckedExpr, UncheckedExpr): Set the
3227 ConstantCheckState as well.
3229 During Resolve, they also have to flag the state, because the
3230 constant folder runs completely in the Resolve phase.
3232 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
3235 2002-03-01 Miguel de Icaza <miguel@ximian.com>
3237 * cfold.cs: New file, this file contains the constant folder.
3239 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
3240 argument to track whether we are using the resulting address to
3241 load or store a value and provide better error messages.
3243 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
3244 new AddressOf arguments.
3246 * statement.cs (Foreach.EmitCollectionForeach): Update
3248 * expression.cs (Argument.Emit): Call AddressOf with proper
3249 arguments to track usage.
3251 (New.DoEmit): Call AddressOf with new arguments.
3253 (Unary.Emit): Adjust AddressOf call.
3255 2002-03-01 Ravi Pratap <ravi@ximian.com>
3257 * cs-parser.jay (member_access): Change the case for pre-defined types
3258 to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
3261 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
3264 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
3265 essentially like methods and apply attributes like MethodImplOptions to them too.
3267 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
3270 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
3271 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
3274 * Update code everywhere accordingly.
3276 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
3278 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
3280 2002-02-28 Ravi Pratap <ravi@ximian.com>
3282 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
3283 try performing lookups against those instead of jumping straight into using
3284 the 'using' clauses.
3286 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
3288 (LookupType): Perform lookups in implicit parents too.
3290 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
3291 sequence as RootContext.LookupType.
3293 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
3294 the various cases of namespace lookups into this method.
3296 2002-03-01 Miguel de Icaza <miguel@ximian.com>
3298 * cs-parser.jay: Add support for [Attribute ()] (empty arguments
3299 in positional arguments)
3301 * class.cs (Operator): Update the AllowedModifiers to contain
3304 * cs-parser.jay: Update operator declaration to allow for the
3305 operator body to be empty.
3307 * cs-tokenizer.cs: Added '\u' unicode support in strings and hex
3310 2002-02-27 Miguel de Icaza <miguel@ximian.com>
3312 * class.cs (Method.Emit): Label parameters.
3314 * driver.cs: Return 1 or 0 as the program exit code.
3316 2002-02-26 Miguel de Icaza <miguel@ximian.com>
3318 * expression.cs: Special case the `null' object when trying to
3319 auto-compute the type, as anything can be explicitly converted to
3322 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
3323 spotting this Paolo.
3325 (Expression.ImplicitNumericConversion): Perform comparissions of
3326 the type using the underlying type in the case of an enumeration
3327 rather than using the enumeration type for the compare.
3329 Cope with the underlying == type case, which is not possible to
3332 (Expression.ConvertNumericExplicit): Perform comparissions of
3333 the type using the underlying type in the case of an enumeration
3334 rather than using the enumeration type for the compare.
3336 * driver.cs: If the user does not supply an extension, assume .exe
3338 * cs-parser.jay (if_statement): Rewrote so that we can track the
3339 location for the if statement.
3341 * expression.cs (Binary.ConstantFold): Only concat strings when
3342 the operation is "+", not everything ;-)
3344 * statement.cs (Statement.EmitBoolExpression): Take a location
3346 (If, While, Do): Track location.
3348 * expression.cs (Binary.ResolveOperator): In the object + string
3349 case, I was missing a call to ConvertImplicit
3351 2002-02-25 Ravi Pratap <ravi@ximian.com>
3353 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
3354 Location arguments. Ensure we use RootContext.LookupType to do our work
3355 and not try to do a direct Type.GetType and ModuleBuilder.GetType
3357 * interface.cs (PopulateMethod): Handle the type of the parameter being
3360 * expression.cs (Invocation.BetterFunction): Handle the case when we
3361 have a params method with no fixed arguments and a call is made with no
3364 2002-02-25 Miguel de Icaza <miguel@ximian.com>
3366 * cs-tokenizer.cs: Add support for the quote-escape-sequence in
3367 the verbatim-string-literal
3369 * support.cs (InternalParameters.ParameterModifier): handle null
3371 (InternalParameters.ParameterType): ditto.
3373 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
3374 duplicating the name of the variable parameter.
3375 (GetParameterByName): Fix bug where we were not looking up array
3376 paramters if they were the only present (thanks Paolo!).
3377 (GetParameterInfo): We only have an empty set of types if both
3378 fixed and array are set to null.
3379 (GetParameterInfo-idx): Handle FixedParameter == null
3381 * cs-parser.jay: Handle the case where there is no catch
3382 statements (missing null test).
3384 2002-02-22 Miguel de Icaza <miguel@ximian.com>
3386 * driver.cs (MainDriver): Be conservative on our command line
3389 Catch DirectoryNotFoundException when calling GetFiles.
3391 (SplitPathAndPattern): Used to split the input specification into
3392 a path and a pattern that we can feed to Directory.GetFiles.
3394 2002-02-21 Miguel de Icaza <miguel@ximian.com>
3396 * statement.cs (Fixed): Implement the last case of the Fixed
3397 statement (string handling).
3399 * expression.cs (StringPtr): New class used to return a char * to
3400 a string; Used by the Fixed statement.
3402 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
3404 * expression.cs (Binary.ResolveOperator): Remove redundant
3405 MemberLookup pn parent type.
3406 Optimize union call, we do not need a union if the types are the same.
3407 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
3410 Specialize the use of MemberLookup everywhere, instead of using
3411 the default settings.
3413 (StackAlloc): Implement stackalloc keyword.
3415 * cs-parser.jay: Add rule to parse stackalloc.
3417 * driver.cs: Handle /h, /help, /?
3419 * expression.cs (MakeByteBlob): Removed the hacks we had in place
3420 before we supported unsafe code.
3422 * makefile: add --unsafe to the self compilation of mcs.
3424 2002-02-20 Miguel de Icaza <miguel@ximian.com>
3426 * expression.cs (PointerArithmetic): New class that is used to
3427 perform pointer arithmetic.
3428 (Binary.Resolve): Handle pointer arithmetic
3429 Handle pointer comparission.
3430 (ArrayPtr): Utility expression class that is used to take the
3431 address of an array.
3433 (ElementAccess): Implement array access for pointers
3435 * statement.cs (Fixed): Implement fixed statement for arrays, we
3436 are missing one more case before we are done.
3438 * expression.cs (Indirection): Implement EmitAssign and set the
3439 ExprClass to Variable. This allows pointer dereferences to be
3440 treated as variables, and to have values assigned to them.
3442 * ecore.cs (Expression.StoreFromPtr): New utility function to
3443 store values dereferencing.
3445 2002-02-20 Ravi Pratap <ravi@ximian.com>
3447 * expression.cs (Binary.ResolveOperator): Ensure that we are
3448 not trying to operate on a void type - this fixes the reported
3451 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
3452 the parent implementation is sealed.
3454 * ../errors/cs0239.cs : Add.
3456 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
3458 * typemanager.cs (unverifiable_code_type): Corresponds to
3459 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
3460 which have unsafe code in them.
3462 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
3465 2002-02-19 Miguel de Icaza <miguel@ximian.com>
3467 * cs-tokenizer.cs: Add support for @"litreal strings"
3469 Make tokenizer accept pre-processor directives
3470 on any column (remove the old C-like limitation).
3472 * rootcontext.cs (EmitCode): Emit any global attributes.
3473 (AddGlobalAttributes): Used to keep track of assembly attributes.
3475 * attribute.cs (ApplyAttributes): Support AssemblyAttributes.
3477 * cs-parser.jay: Add support for global attributes.
3479 2002-02-17 Miguel de Icaza <miguel@ximian.com>
3481 * expression.cs (Indirection): New helper class. Unary will
3482 create Indirection classes to be able to implement the
3483 IMemoryLocation interface on it.
3485 2002-02-16 Miguel de Icaza <miguel@ximian.com>
3487 * cs-parser.jay (fixed_statement): reference the right statement.
3489 * statement.cs (Fixed.Emit): Finish implementing the fixed
3490 statement for the &x case.
3492 2002-02-14 Miguel de Icaza <miguel@ximian.com>
3494 * class.cs (Property.Define, Method.Define): Remove newslot when
3497 * modifiers.cs: My use of NewSlot when `Abstract' was set was
3498 wrong. NewSlot should only be used if the `new' keyword is present.
3500 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
3501 locating our system dir. Sorry about this.
3503 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3505 * driver.cs (GetSystemDir): Compute correctly the location of our
3506 system assemblies. I was using the compiler directory instead of
3507 the library directory.
3509 2002-02-13 Ravi Pratap <ravi@ximian.com>
3511 * expression.cs (BetterFunction): Put back in what Miguel commented out
3512 since it is the correct fix. The problem is elsewhere ;-)
3514 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
3515 parameters of the parms method are themselves compatible or not !
3517 (StandardConversionExists): Fix very dangerous bug where we were forgetting
3518 to check that a class implements an interface before saying that an implicit
3519 conversion was allowed. Use ImplementsInterface to do the checking.
3521 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3523 * class.cs (Method.Define): Track whether we are an explicit
3524 implementation or not. And only call DefineMethodOverride if we
3525 are an explicit implementation.
3527 (Property.DefineMethod): Ditto.
3529 2002-02-11 Ravi Pratap <ravi@ximian.com>
3531 * expression.cs (BetterFunction): Catch hideous bug which was
3532 preventing us from detecting ambiguous calls due to implicit casts i.e
3535 2002-01-29 Miguel de Icaza <miguel@ximian.com>
3537 * support.cs (Pair): Remove un-needed method. I figured why I was
3538 getting the error in cs-parser.jay, the variable in a foreach loop
3539 is readonly, and the compiler does not really treat this as a variable.
3541 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
3542 instead of EQUALS in grammar.
3544 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
3546 * expression.cs (Unary.DoResolve): Check whether the argument is
3549 2002-01-28 Miguel de Icaza <miguel@ximian.com>
3551 * support.cs: Api for Pair to set a value. Despite the fact that
3552 the variables are public the MS C# compiler refuses to compile
3553 code that accesses the field if the variable is part of a foreach
3556 * statement.cs (Fixed): Begin implementation of the fixed
3559 (Block.AddVariable): Return the VariableInfo on success and null
3560 on failure instead of true/false.
3562 * cs-parser.jay (foreach): Catch errors on variables already
3563 defined (we were ignoring this value before) and properly unwind
3566 (fixed_statement): grammar for the fixed statement.
3568 2002-01-25 Miguel de Icaza <miguel@ximian.com>
3570 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
3571 pointer types to be incretemented.
3573 (SizeOf): Implement.
3575 * cs-parser.jay (pointer_member_access): Implement
3576 expr->IDENTIFIER production.
3578 * expression.cs (IndexerAccess.DoResolve, ArrayAccess.DoResolve,
3579 MemberAccess.DoResolve, Invocation.DoResolve): Check for pointers
3582 (Unary): Implement indirection.
3584 * ecore.cs (Expression.UnsafeError): Reports error 214 (pointer
3585 use in non-unsafe context).
3587 (SimpleName.DoResolve): Check for pointers in field access on safe
3590 (Expression.LoadFromPtr): Factor the load-indirect code in this
3591 function. This was duplicated in UnboxCast and ParameterReference
3593 2002-01-24 Miguel de Icaza <miguel@ximian.com>
3595 * expression.cs (ComposedCast): report an error if a pointer cast
3596 is used in a safe region.
3598 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
3599 pointer type casts in unsafe context.
3601 * codegen.cs (EmitContext): Set up IsUnsafe.
3603 * cs-parser.jay (non_expression_type): Add productions for pointer
3606 * expression.cs (Invocation.EmitCall): Remove chunk of buggy
3607 code. We should not use force into static mode if the method is
3608 not virtual. Fixes bug in MIS
3610 * statement.cs (Do.Emit, While.Emit, For.Emit,
3611 Statement.EmitBoolExpression): Add support to Do and While to
3612 propagate infinite loop as `I do return' semantics.
3614 Improve the For case to also test for boolean constants.
3616 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
3617 to the list of attributes we can add.
3619 Remove `EmitContext' argument.
3621 * class.cs (Method.Define): Apply parameter attributes.
3622 (Constructor.Define): Apply parameter attributes.
3623 (MethodCore.LabelParameters): Move here the core of labeling
3626 * support.cs (ReflectionParameters.ParameterModifier,
3627 InternalParameters.ParameterModifier): Use IsByRef on the type and
3628 only return the OUT bit for these parameters instead of in/out/ref
3631 This is because I miss-understood things. The ParameterInfo.IsIn
3632 and IsOut represent whether the parameter has the [In] and [Out]
3635 2002-01-22 Miguel de Icaza <miguel@ximian.com>
3637 * ecore.cs (FieldExpr.Emit): Release temporaries.
3639 * assign.cs (LocalTemporary.Release): new function.
3641 * codegen.cs (EmitContext.GetTemporaryStorage,
3642 EmitContext.FreeTemporaryStorage): Rework the way we deal with
3643 temporary storage. Now we can "put back" localbuilders when we
3646 2002-01-21 Miguel de Icaza <miguel@ximian.com>
3648 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
3649 need to make a copy of the variable to generate verifiable code.
3651 2002-01-19 Miguel de Icaza <miguel@ximian.com>
3653 * driver.cs: Compute dynamically the system directory.
3655 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
3656 Slower, but more generally useful. Used by the abstract
3657 registering implementation.
3659 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
3660 the rules for the special rule on Type/instances. First check if
3661 we have the same name, and if so, try that special static path
3662 rather than the instance path.
3664 2002-01-18 Miguel de Icaza <miguel@ximian.com>
3666 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
3669 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
3670 Enum, ValueType, Delegate or Array for non-corlib compiles.
3672 * cs-tokenizer.cs: Catch long identifiers (645)
3674 * typemanager.cs (IndexerPropetyName): Ravi never tested this
3677 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
3678 fix, we were returning too early, so we were not registering
3679 pending methods from abstract classes.
3681 Do not register pending methods if the class is abstract.
3683 * expression.cs (Conditional.DoResolve): Report circular implicit
3684 conversions when we neecd to compute it for conditional
3687 (Is.DoResolve): If the expression is always of the provided type,
3688 flag warning 183. If the expression can not ever be of the
3689 provided type flag warning 184.
3691 * class.cs: Catch 169 as well.
3693 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
3696 2002-01-18 Nick Drochak <ndrochak@gol.com>
3698 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.

3702 * interface.cs: (PopulateMethod): Check for pointers being defined
3703 only if the unsafe context is active.
3704 (PopulateProperty): ditto.
3705 (PopulateIndexer): ditto.
3707 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
3708 specified. If pointers are present, make sure that they are
3709 present in an unsafe context.
3710 (Constructor, Constructor.Define): ditto.
3711 (Field, Field.Define): ditto.
3712 (Property, Property.Define): ditto.
3713 (Event, Event.Define): ditto.
3715 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
3716 hashtable if there are classes or structs defined.
3718 * expression.cs (LocalVariableReference.DoResolve): Simplify this
3719 code, as the constant resolution moved.
3721 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
3722 the metadata, so we can flag error 133.
3724 * decl.cs (MemberCore.UnsafeOK): New function to test that a
3725 pointer is being declared in an unsafe context.
3727 2002-01-16 Miguel de Icaza <miguel@ximian.com>
3729 * modifiers.cs (Modifiers.Check): Require a Location argument.
3730 Report error 227 for Unsafe use.
3732 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
3734 * statement.cs (For.Emit): If the test is null, then report that
3735 we do `return', as we wont reach anything afterwards.
3737 (Switch.SwitchGoverningType): Track the expression that matched
3740 * driver.cs: Allow negative numbers as an error code to flag.
3742 * cs-parser.jay: Handle 1551.
3744 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
3746 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3748 * cs-parser.jay: Report 1518 (type declaration can only contain
3749 class, struct, interface, enum or delegate)
3751 (switch_label): Report 1523 (keywords `case' or `default' must
3754 (opt_switch_sections): Report 1522 (empty switch)
3756 * driver.cs: Report 1515 (response file specified multiple times)
3757 Report 1516 (Source file specified multiple times).
3759 * expression.cs (Argument.Resolve): Signal 1510
3761 (BaseAccess.Resolve, BaseIndexer.Resolve): Signal 1511 (base
3762 access not allowed in static code)
3764 2002-01-11 Ravi Pratap <ravi@ximian.com>
3766 * typemanager.cs (IsPointerType): Utility method which we are going
3769 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
3770 the object type, so we take care of that.
3772 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
3774 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
3775 added to non-params parameters :-)
3777 * typemanager.cs (CSharpName): Include 'void' type too.
3779 (void_ptr_type): Include in the set of core types.
3781 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
3784 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
3787 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
3788 completely forgotten about it.
3790 2002-01-10 Ravi Pratap <ravi@ximian.com>
3792 * cs-parser.jay (pointer_type): Add. This begins our implementation
3793 of parsing rules for unsafe code.
3795 (unsafe_statement): Implement.
3797 (embedded_statement): Modify to include the above.
3799 * statement.cs (Unsafe): Implement new class for unsafe blocks.
3801 * codegen.cs (EmitContext.InUnsafe): Add. This determines
3802 if the current context is an unsafe one.
3804 * cs-parser.jay (local_variable_pointer_type): Since local variable types
3805 are handled differently, we need separate rules for them.
3807 (local_variable_declaration): Update to use local_variable_pointer_type
3808 to allow variable declarations of unmanaged pointer types.
3810 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
3813 * ../errors/cs0214.cs : Add.
3815 2002-01-16 Nick Drochak <ndrochak@gol.com>
3817 * makefile: remove 'response' file when cleaning.
3819 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3821 * cs-parser.jay: Report 1524.
3823 2002-01-14 Miguel de Icaza <miguel@ximian.com>
3825 * typemanager.cs (RegisterMethod): drop checking if we have
3826 registered this from here
3828 2002-01-12 Miguel de Icaza <miguel@ximian.com>
3830 * class.cs (Method.EmitDestructor): Implement calling our base
3833 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
3836 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
3837 this routine and will wrap the call in a try/catch block. Deal
3840 2002-01-11 Miguel de Icaza <miguel@ximian.com>
3842 * ecore.cs (Expression.MemberLookup): instead of taking a
3843 parameter `same_type' that was used to tell whether we could
3844 access private members we compute our containing type from the
3847 (FieldExpr): Added partial support for volatile fields. This does
3848 not work for volatile fields exposed from assemblies, as I can not
3849 figure out how to extract the modreq from it.
3851 Updated all the source files to use this.
3853 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
3854 because it is referenced by MemberLookup very often.
3856 2002-01-09 Ravi Pratap <ravi@ximian.com>
3858 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
3859 TypeBuilder.GetCustomAttributes to retrieve what we need.
3861 Get rid of redundant default_member_attr_type as this is the same as
3862 default_member_type which already exists.
3864 * interface.cs, attribute.cs : Update accordingly.
3866 2002-01-08 Miguel de Icaza <miguel@ximian.com>
3868 * typemanager.cs: Enable IndexerPropertyName again. It does not
3869 work for TYpeBuilders though. Ravi, can you please fix this?
3871 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
3873 * expression.cs (Argument.Emit): Handle the case of ref objects
3874 being passed to ref functions;
3876 (ParameterReference.EmitLoad): Loads the content of the pointer
3877 without dereferencing.
3879 2002-01-07 Miguel de Icaza <miguel@ximian.com>
3881 * cs-tokenizer.cs: Implemented the pre-processing expressions.
3883 2002-01-08 Ravi Pratap <ravi@ximian.com>
3885 * class.cs (Indexer.DefineMethod): Incorporate the interface
3886 type in the name of the method if we are doing explicit interface
3889 * expression.cs (ConversionExists): Remove as it is completely obsolete.
3891 (BetterConversion): Fix extremely trivial bug where we were referring to
3892 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
3895 * ../errors/bug16.cs : Add although we have fixed it.
3897 2002-01-07 Miguel de Icaza <miguel@ximian.com>
3899 * expression.cs (BaseIndexer): Begin implementation.
3901 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
3903 * cs-parser.jay (indexer_declarator): Use qualified_identifier
3904 production directly to remove a shift/reduce, and implement
3905 explicit interface implementation.
3907 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
3908 after a floating point suffix.
3910 * expression.cs (DoNumericPromotions): Improved the conversion for
3911 uint/uint. If we have a constant, we avoid doing a typecast to a
3914 * class.cs (Indexer): Implement explicit interface implementation
3917 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
3919 * class.cs: make the default instance constructor public and hidebysig.
3921 2001-01-03 Ravi Pratap <ravi@ximian.com>
3923 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
3924 so we can call it from elsewhere.
3926 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
3927 we emit it internally if the class has a defined indexer; otherwise the user
3928 emits it by decorating the class definition with the DefaultMemberAttribute.
3930 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
3931 attribute is not used on a type which defines an indexer.
3933 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
3934 character when we skip whitespace.
3936 * ../errors/cs0646.cs : Add.
3938 2002-01-03 Miguel de Icaza <miguel@ximian.com>
3940 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
3943 * makefile: Add practical target `mcs3.exe' which builds the third
3944 generation compiler.
3946 * expression.cs (New): Fix structures constructor calling.
3948 * class.cs (Property, Method, Indexer): Emit Final flag on the
3949 method if we are an interface implementation and we are not
3952 * ecore.cs (PropertyExpr): New public field `IsBase', tells
3953 whether this property is referencing a `base' method.
3955 * expression.cs (Invocation.EmitCall): take an extra argument:
3956 is_base, this is used to determine whether the `call' or
3957 `callvirt' opcode should be used.
3960 * delegate.cs: update EmitCall.
3962 * class.cs (Method.Define): Set NewSlot for the cases where we are
3963 not implementing an interface method.
3965 (Property.Define): ditto.
3967 2002-01-02 Miguel de Icaza <miguel@ximian.com>
3969 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
3970 'r'. Allows mcs to parse itself fully.
3972 2002-01-02 Ravi Pratap <ravi@ximian.com>
3974 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
3975 of the number of initializers that require the InitializeArray method.
3977 (CheckIndices): Store the Expression in all cases - not the plain value. Also
3978 update the above field where necessary.
3980 (MakeByteBlob): Update accordingly.
3982 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
3985 (EmitDynamicInitializers): Update in accordance with the new optimization.
3987 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
3988 same OpCode applies.
3990 * cs-parser.jay : Fix some glaring errors I introduced.
3992 2002-01-01 Ravi Pratap <ravi@ximian.com>
3994 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
3995 so that we can check for name clashes there too.
3997 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
3998 for interface indexers.
4000 * interfaces.cs (Define): Emit the default member attribute.
4002 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
4003 variable was being referred to while setting the value ;-)
4005 2002-01-01 Miguel de Icaza <miguel@ximian.com>
4007 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
4008 byte-by-byte information when we know the data is zero.
4010 Make the block always a multiple of 4, because
4011 DefineInitializedData has a bug.
4013 * assign.cs: Fix, we should assign from the temporary, not from
4016 * expression.cs (MakeByteBlob): Fix my incorrect code.
4018 2001-12-31 Miguel de Icaza <miguel@ximian.com>
4020 * typemanager.cs (EnumToUnderlying): This function is used to get
4021 the underlying type from an enumeration, because it does not
4024 * constant.cs: Use the I4_S form for values between -128 and 127.
4026 * statement.cs (Block.LookupLabel): Looks up a label.
4027 (Block): Drop support for labeled blocks.
4029 (LabeledStatement): New kind of statement that represents a label
4032 (Goto): Finally implement this bad boy.
4034 * cs-parser.jay: Update to reflect new mechanism to implement
4037 2001-12-30 Miguel de Icaza <miguel@ximian.com>
4039 * codegen.cs (EmitContext.This): a codegen property that keeps the
4040 a single instance of this instead of creating many different this
4043 * delegate.cs (Delegate.DoResolve): Update to use the property;
4045 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
4047 * expression.cs (BaseAccess.DoResolve): Ditto.
4049 2001-12-29 Ravi Pratap <ravi@ximian.com>
4051 * typemanager.cs (methodimpl_attr_type): Add to hold the type
4052 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
4054 (InitCoreTypes): Update accordingly.
4056 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
4057 so we can quickly store the state.
4059 (ApplyAttributes): Set the correct implementation flags
4060 for InternalCall methods.
4062 2001-12-29 Miguel de Icaza <miguel@ximian.com>
4064 * expression.cs (EmitCall): if a method is not virtual, then do
4065 not use callvirt on it.
4067 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
4068 user defined stuff) requires the use of stobj, which takes an
4069 address on the stack instead of an array and an index. So emit
4070 the Ldelema operation for it.
4072 (EmitStoreOpcode): Use stobj for valuetypes.
4074 (UnaryMutator.EmitCode): Use the right 1 value depending on
4075 whether we are dealing with int64/uint64, float or doubles.
4077 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
4078 constructors that I implemented last night.
4080 (Constructor.IsDefault): Fix to work properly for static
4083 * cs-parser.jay (CheckDef): report method signature errors.
4084 Update error number 103 to be 132.
4086 * decl.cs: New AdditionResult enumeration value: MethodExists.
4087 Although we do this check for methods later on in the semantic
4088 analysis, catching repeated default constructors is so easy that
4089 we catch these here.
4091 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
4094 (ParameterReference.EmitAssign, Emit): handle
4097 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
4098 (ArrayAccess.EmitStoreOpcode): ditto.
4100 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
4102 * expression.cs (MakeByteBlob): Complete all the missing types
4103 (uint, short, ushort, byte, sbyte)
4105 * class.cs: Only init instance field initializers on instance
4108 Rename `constructors' to instance_constructors.
4110 (TypeContainer.AddConstructor): Only add constructors to the list
4111 if it is not static.
4113 Make sure that we handle default_static_constructor independently
4114 everywhere where we handle instance_constructors
4116 2001-12-28 Miguel de Icaza <miguel@ximian.com>
4118 * class.cs: Do not lookup or create a base initializer for a
4121 (ConstructorInitializer.Resolve): use the proper type to lookup
4124 * cs-parser.jay: Report error 1585 (modifiers between type and name).
4126 * enum.cs, interface.cs: Remove CloseType, this is taken care by
4129 * decl.cs: CloseType is now an virtual method, the default
4130 implementation just closes this type.
4132 2001-12-28 Ravi Pratap <ravi@ximian.com>
4134 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
4135 to PreserveSig by default. Also emit HideBySig on such methods.
4137 Basically, set the defaults to standard values.
4139 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
4140 argument, if candidate is better, it can't be worse than the best !
4142 (Invocation): Re-write bits to differentiate between methods being
4143 applicable in their expanded form and their normal form - for params
4146 Get rid of use_standard everywhere as only standard conversions are allowed
4147 in overload resolution.
4149 More spec conformance.
4151 2001-12-27 Miguel de Icaza <miguel@ximian.com>
4153 * driver.cs: Add --timestamp, to see where the compiler spends
4156 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
4157 `this' in static code.
4159 (SimpleName.DoResolve): Implement in terms of a helper function
4160 that allows static-references to be passed upstream to
4163 (Expression.ResolveWithSimpleName): Resolve specially simple
4164 names when called by MemberAccess to implement the special
4167 (Expression.ImplicitReferenceConversion): Handle conversions from
4168 Null to reference types before others, as Null's type is
4171 * expression.cs (Invocation.EmitCall): Handle the special case of
4172 calling methods declared on a reference type from a ValueType
4173 (Base classes System.Object and System.Enum)
4175 (MemberAccess.Resolve): Only perform lookups on Enumerations if
4176 the left hand side is a TypeExpr, not on every enumeration.
4178 (Binary.Resolve): If types are reference types, then do a cast to
4179 object on operators != and == of both arguments.
4181 * typemanager.cs (FindMembers): Extract instance and static
4182 members if requested.
4184 * interface.cs (PopulateProperty): Use void_type instead of null
4185 as the return type for the setter method.
4187 (PopulateIndexer): ditto.
4189 2001-12-27 Ravi Pratap <ravi@ximian.com>
4191 * support.cs (ReflectionParameters): Fix minor bug where we
4192 were examining the wrong parameter for the ParamArray attribute.
4194 Cope with requests for the type of the parameter at position
4195 greater than the params parameter's. We now return the element
4196 type of the params array as that makes more sense.
4198 * expression.cs (Invocation.IsParamsMethodApplicable): Update
4199 accordingly as we no longer have to extract the element type
4202 (Invocation.OverloadResolve): Update.
4204 2001-12-27 Miguel de Icaza <miguel@ximian.com>
4206 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
4207 against IEnumerator, test whether the return value is a descendant
4208 of the IEnumerator interface.
4210 * class.cs (Indexer.Define): Use an auxiliary method to implement
4211 the other bits of the method definition. Begin support for
4212 explicit interface implementation.
4214 (Property.DefineMethod): Use TypeManager.void_type instead of null
4215 for an empty return value.
4217 2001-12-26 Miguel de Icaza <miguel@ximian.com>
4219 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
4220 dealing with a FieldExpr which is composed of a FieldBuilder, in
4221 the code path we did extract the constant, but we should have
4222 obtained the underlying value to be able to cast it (otherwise we
4223 end up in an infinite loop, this is what Ravi was running into).
4225 (ArrayCreation.UpdateIndices): Arrays might be empty.
4227 (MemberAccess.ResolveMemberAccess): Add support for section
4228 14.5.4.1 that deals with the special case of E.I when E is a type
4229 and something else, that I can be a reference to a static member.
4231 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
4232 handle a particular array type to create byte blobs, it is just
4233 something we dont generate byteblobs for.
4235 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
4238 * location.cs (Push): remove the key from the hashtable that we
4239 are about to add. This happens for empty files.
4241 * driver.cs: Dispose files after we have parsed them.
4243 (tokenize): new function that only runs the tokenizer on its
4244 input, for speed testing.
4246 2001-12-26 Ravi Pratap <ravi@ximian.com>
4248 * class.cs (Event.Define): Define the private field only if there
4249 are no accessors defined.
4251 * expression.cs (ResolveMemberAccess): If there is no associated
4252 field with the event, that means we have an event defined with its
4253 own accessors and we should flag error cs0070 since transforming
4254 ourselves into a field is not valid in that case.
4256 * ecore.cs (SimpleName.DoResolve): Same as above.
4258 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
4259 and charset to sane values.
4261 2001-12-25 Ravi Pratap <ravi@ximian.com>
4263 * assign.cs (DoResolve): Perform check on events only if they
4264 are being accessed outside the declaring type.
4266 * cs-parser.jay (event_declarations): Update rules to correctly
4267 set the type of the implicit parameter etc.
4269 (add_accessor, remove_accessor): Set current local parameters.
4271 * expression.cs (Binary): For delegate addition and subtraction,
4272 cast the return value from the method into the appropriate delegate
4275 2001-12-24 Ravi Pratap <ravi@ximian.com>
4277 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
4278 of these as the workaround is unnecessary.
4280 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
4281 delegate data - none of that is needed at all.
4283 Re-write bits to extract the instance expression and the delegate method
4286 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
4289 * attribute.cs (ApplyAttributes): New method to take care of common tasks
4290 of attaching attributes instead of duplicating code everywhere.
4292 * everywhere : Update code to do attribute emission using the above method.
4294 2001-12-23 Miguel de Icaza <miguel@ximian.com>
4296 * expression.cs (IsParamsMethodApplicable): if there are not
4297 parameters, return immediately.
4299 * ecore.cs: The 0 literal can be implicity converted to an enum
4302 (SimpleName.DoResolve): First lookup the type, then lookup the
4305 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
4306 want to get its address. If the InstanceExpression is not
4307 addressable, store the result in a temporary variable, then get
4310 * codegen.cs: Only display 219 errors on warning level or above.
4312 * expression.cs (ArrayAccess): Make it implement the
4313 IMemoryLocation interface.
4315 (Binary.DoResolve): handle the operator == (object a, object b)
4316 and operator != (object a, object b) without incurring into a
4317 BoxedCast (because 5 != o should never be performed).
4319 Handle binary enumerator operators.
4321 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
4322 value type, otherwise use Ldelem_ref.
4324 Use precomputed names;
4326 (AddressOf): Implement address of
4328 * cs-parser.jay (labeled_statement): Fix recursive block
4329 addition by reworking the production.
4331 * expression.cs (New.DoEmit): New has a special case:
4333 If we are dealing with a ValueType, we have a few
4334 situations to deal with:
4336 * The target of New is a ValueType variable, that is
4337 easy, we just pass this as the variable reference
4339 * The target of New is being passed as an argument,
4340 to a boxing operation or a function that takes a
4343 In this case, we need to create a temporary variable
4344 that is the argument of New.
4347 2001-12-23 Ravi Pratap <ravi@ximian.com>
4349 * rootcontext.cs (LookupType): Check that current_type is not null before
4350 going about looking at nested types.
4352 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
4353 not implement the IAssignMethod interface any more.
4355 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
4356 where we tranform them into FieldExprs if they are being resolved from within
4359 * ecore.cs (SimpleName.DoResolve): Do the same here.
4361 * assign.cs (DoResolve, Emit): Clean up code considerably.
4363 * ../errors/bug10.cs : Add.
4365 * ../errors/cs0070.cs : Add.
4367 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
4369 * assign.cs : Get rid of EventIsLocal everywhere.
4371 2001-12-23 Miguel de Icaza <miguel@ximian.com>
4373 * ecore.cs (ConvertIntLiteral): finished the implementation.
4375 * statement.cs (SwitchLabel): Convert the value we are using as a
4376 key before looking up the table.
4378 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4380 * codegen.cs (EmitTopBlock): Require a Location argument now.
4382 * cs-parser.jay (constructor_declarator): We need to setup
4383 current_local_parameters before we parse the
4384 opt_constructor_initializer, to allow the variables to be bound
4385 to the constructor arguments.
4387 * rootcontext.cs (LookupType): First lookup nested classes in our
4388 class and our parents before we go looking outside our class.
4390 * expression.cs (ConstantFold): Extract/debox the values at the
4393 * rootcontext.cs (EmitCode): Resolve the constants first before we
4394 resolve the types. This is not really needed, but it helps debugging.
4396 * statement.cs: report location.
4398 * cs-parser.jay: pass location to throw statement.
4400 * driver.cs: Small bug fix.
4402 * report.cs: Updated format to be 4-zero filled digits.
4404 2001-12-22 Ravi Pratap <ravi@ximian.com>
4406 * expression.cs (CheckIndices): Fix minor bug where the wrong
4407 variable was being referred to ;-)
4409 (DoEmit): Do not call EmitStaticInitializers when the
4410 underlying type is System.Object.
4412 2001-12-21 Ravi Pratap <ravi@ximian.com>
4414 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
4415 and do the usual workaround for SRE.
4417 * class.cs (MyEventBuilder.EventType): New member to get at the type
4418 of the event, quickly.
4420 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
4422 * assign.cs (Assign.DoResolve): Handle the case when the target
4423 is an EventExpr and perform the necessary checks.
4425 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
4428 (SimpleName.MemberStaticCheck): Include check for EventExpr.
4430 (EventExpr): Set the type in the constructor itself since we
4431 are meant to be born fully resolved.
4433 (EventExpr.Define): Revert code I wrote earlier.
4435 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
4436 instance expression is null. The instance expression is a This in that case
4437 or a null, depending on whether it is a static method or not.
4439 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
4440 refers to more than one method.
4442 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
4443 and accordingly flag errors.
4445 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4447 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
4449 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4451 * location.cs (ToString): Provide useful rutine.
4453 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4455 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
4456 objects, return the actual integral boxed.
4458 * statement.cs (SwitchLabel): define an ILLabel for each
4461 (Switch.CheckSwitch): If the value is a Literal, extract
4462 the underlying literal.
4464 Also in the unused hashtable we had, add the SwitchLabel so we can
4465 quickly look this value up.
4467 * constant.cs: Implement a bunch of new constants. Rewrite
4468 Literal based on this. Made changes everywhere to adapt to this.
4470 * expression.cs (Expression.MakeByteBlob): Optimize routine by
4471 dereferencing array only once, and also copes with enumrations.
4473 bytes are two bytes wide, not one.
4475 (Cast): Perform constant conversions.
4477 * ecore.cs (TryImplicitIntConversion): Return literals instead of
4478 wrappers to the literals here.
4480 * expression.cs (DoNumericPromotions): long literals can converted
4481 to ulong implicity (this is taken care of elsewhere, but I was
4484 * ecore.cs (Expression.Literalize): Make the return type Literal,
4485 to improve type checking.
4487 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
4489 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4491 * literal.cs: Revert code from ravi that checked the bounds. The
4492 bounds are sane by the definition of the type itself.
4494 * typemanager.cs: Fix implementation of ImplementsInterface. We
4495 need to actually look up in our parent hierarchy for interfaces
4498 * const.cs: Use the underlying type for enumerations
4500 * delegate.cs: Compute the basename for the delegate creation,
4501 that should fix the delegate test case, and restore the correct
4502 Type Lookup semantics in rootcontext
4504 * rootcontext.cs: Revert Ravi's last patch. The correct way of
4505 referencing a nested type with the Reflection API is using the "+"
4508 * cs-parser.jay: Do not require EOF token at the end.
4510 2001-12-20 Ravi Pratap <ravi@ximian.com>
4512 * rootcontext.cs (LookupType): Concatenate type names with
4513 a '.' instead of a '+' The test suite passes again.
4515 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
4516 field of the enumeration.
4518 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
4519 the case when the member is an EventExpr.
4521 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
4522 static has an associated instance expression.
4524 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
4526 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
4528 * class.cs (Event.Define): Register event and perform appropriate checks
4531 We define the Add and Remove methods even if the use provides none because
4532 in that case, we provide default implementations ourselves.
4534 Define a private field of the type of the event. This is done by the CSC compiler
4535 and we should be doing it too ;-)
4537 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
4538 More methods we use in code we generate.
4540 (multicast_delegate_type, delegate_type): Two separate types since the distinction
4543 (InitCoreTypes): Update accordingly for the above.
4545 * class.cs (Event.Emit): Generate code for default accessors that we provide
4547 (EmitDefaultMethod): Do the job in the above.
4549 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
4552 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4554 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
4555 builders even if we were missing one.
4557 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
4558 pass the Basename as our class name instead of the Name. The
4559 basename will be correctly composed for us.
4561 * parameter.cs (Paramters): Now takes a Location argument.
4563 * decl.cs (DeclSpace.LookupType): Removed convenience function and
4564 make all the code call directly LookupType in RootContext and take
4565 this chance to pass the Location information everywhere.
4567 * Everywhere: pass Location information.
4569 2001-12-19 Miguel de Icaza <miguel@ximian.com>
4571 * class.cs (Constructor.Define): Updated way of detecting the
4572 length of the parameters.
4574 (TypeContainer.DefineType): Use basename as the type name for
4577 (TypeContainer.Define): Do not recursively define types here, as
4578 definition is taken care in order by the RootContext.
4580 * tree.cs: Keep track of namespaces in a per-file basis.
4582 * parameter.cs (Parameter.ComputeSignature): Update to use
4585 (Parameters.GetSignature): ditto.
4587 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
4588 instead of a TypeContainer.
4590 (Interface.SemanticAnalysis): Use `this' instead of our parent to
4591 resolve names. Because we need to be resolve in our context, not
4594 * driver.cs: Implement response files.
4596 * class.cs (TypeContainer.DefineType): If we are defined, do not
4599 (Event.Emit): Emit the code for add/remove handlers.
4600 (Event.Define): Save the MethodBuilders for add/remove.
4602 * typemanager.cs: Use pair here too.
4604 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
4605 DictionaryEntry requires the first argument to be non-null.
4607 (enum_declaration): Compute full name for registering the
4610 (delegate_declaration): Instead of using
4611 formal_parameter_list, use opt_formal_parameter_list as the list
4614 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
4615 (EventParsing): New property that controls whether `add' and
4616 `remove' are returned as tokens or identifiers (for events);
4618 2001-12-19 Ravi Pratap <ravi@ximian.com>
4620 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
4621 use MyEventBuilder only and let it wrap the real builder for us.
4623 (MyEventBuilder): Revamp constructor etc.
4625 Implement all operations that we perform on EventBuilder in precisely the same
4628 (FindMembers): Update to use the EventBuilder member.
4630 (Event.Emit): Update accordingly.
4632 2001-12-18 Ravi Pratap <ravi@ximian.com>
4634 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
4635 by calling the appropriate methods.
4637 (GetCustomAttributes): Make stubs as they cannot possibly do anything
4640 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
4642 2001-12-17 Ravi Pratap <ravi@ximian.com>
4644 * delegate.cs (Delegate.Populate): Check that the return type
4645 and various parameters types are indeed accessible.
4647 * class.cs (Constructor.Define): Same here.
4649 (Field.Define): Ditto.
4651 (Event.Define): Ditto.
4653 (Operator.Define): Check that the underlying Method defined itself
4654 correctly - so it's MethodBuilder should not be null.
4656 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
4657 expression happens to be null.
4659 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
4660 members but as of now we don't seem to be able to do anything really useful with it.
4662 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
4663 not the EventBuilder.
4665 2001-12-18 Miguel de Icaza <miguel@ximian.com>
4667 * cs-tokenizer.cs: Add support for defines.
4668 Add support for #if, #elif, #else, #endif
4670 (eval_var): evaluates a variable.
4671 (eval): stubbed for evaluating functions.
4673 * cs-parser.jay: Pass the defines information
4675 * driver.cs: Add --define command line option.
4677 * decl.cs: Move MemberCore here.
4679 Make it the base class for DeclSpace. This allows us to catch and
4680 report 108 and 109 for everything now.
4682 * class.cs (TypeContainer.Define): Extract all the members
4683 before populating and emit the warning 108 (new keyword required
4684 to override) instead of having each member implement this.
4686 (MemberCore.Define): New abstract method, we will be using this in
4687 the warning reporting engine in Populate.
4689 (Operator.Define): Adjust to new MemberCore protocol.
4691 * const.cs (Const): This does not derive from Expression, it is a
4692 temporary object we use to create fields, it is a MemberCore.
4694 * class.cs (Method.Define): Allow the entry point to be in a
4697 * driver.cs: Rewrite the argument handler to clean it up a bit.
4699 * rootcontext.cs: Made it just an auxiliary namespace feature by
4700 making everything static.
4702 * driver.cs: Adapt code to use RootContext type name instead of
4705 * delegate.cs: Remove RootContext argument.
4707 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
4710 * class.cs (Event.Define): The lookup can fail.
4712 * cs-tokenizer.cs: Begin implementation of pre-procesor.
4714 * expression.cs: Resolve the this instance before invoking the code.
4716 2001-12-17 Miguel de Icaza <miguel@ximian.com>
4718 * cs-parser.jay: Add a production in element_access that allows
4719 the thing to become a "type" reference. This way we can parse
4720 things like "(string [])" as a type.
4722 Note that this still does not handle the more complex rules of
4726 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
4728 * ecore.cs: (CopyNewMethods): new utility function used to
4729 assemble the list of methods from running FindMembers.
4731 (MemberLookup): Rework FindMembers so that
4733 2001-12-16 Miguel de Icaza <miguel@ximian.com>
4735 * class.cs (TypeContainer): Remove Delegates who fail to be
4738 * delegate.cs (Populate): Verify that we dont get null return
4739 values. TODO: Check for AsAccessible.
4741 * cs-parser.jay: Use basename to emit error 574 (destructor should
4742 have the same name as container class), not the full name.
4744 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
4745 possible representation.
4747 Also implements integer type suffixes U and L.
4749 2001-12-15 Miguel de Icaza <miguel@ximian.com>
4751 * expression.cs (ArrayCreation.DoResolve): We need to do the
4752 argument resolution *always*.
4754 * decl.cs: Make this hold the namespace. Hold the root context as
4756 (LookupType): Move here.
4758 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
4760 * location.cs (Row, Name): Fixed the code, it was always returning
4761 references to the first file.
4763 * interface.cs: Register properties defined through interfaces.
4765 * driver.cs: Add support for globbing on the command line
4767 * class.cs (Field): Make it derive from MemberCore as well.
4770 2001-12-15 Ravi Pratap <ravi@ximian.com>
4772 * class.cs (Event::Define): Check that the type of the event is a delegate
4773 type else flag error #66.
4775 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
4778 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
4779 values of EntryPoint, CharSet etc etc.
4781 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
4783 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
4784 be null and we should ignore this. I am not sure if this is really clean. Apparently,
4785 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
4786 which needs this to do its work.
4788 * ../errors/cs0066.cs : Add.
4790 2001-12-14 Miguel de Icaza <miguel@ximian.com>
4792 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
4795 * class.cs: (MethodSignature.MethodSignature): Removed hack that
4796 clears out the parameters field.
4797 (MemberSignatureCompare): Cleanup
4799 (MemberCore): New base class used to share code between MethodCore
4802 (RegisterRequiredImplementations) BindingFlags.Public requires
4803 either BindingFlags.Instace or Static. Use instance here.
4805 (Property): Refactored code to cope better with the full spec.
4807 * parameter.cs (GetParameterInfo): Return an empty array instead
4810 * class.cs (Property): Abstract or extern properties have no bodies.
4812 * parameter.cs (GetParameterInfo): return a zero-sized array.
4814 * class.cs (TypeContainer.MethodModifiersValid): Move all the
4815 method modifier validation to the typecontainer so we can reuse
4818 (MethodCore.ParameterTypes): return an empty sized array of types.
4820 (Property.Define): Test property modifier validity.
4822 Add tests for sealed/override too.
4824 (Method.Emit): abstract or extern methods have no bodies.
4826 2001-12-14 Ravi Pratap <ravi@ximian.com>
4828 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
4831 (Method::Define, ::Emit): Modify accordingly.
4833 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
4835 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
4837 * makefile: Pass in /unsafe.
4839 2001-12-13 Miguel de Icaza <miguel@ximian.com>
4841 * class.cs (MakeKey): Kill routine.
4843 * class.cs (TypeContainer.Define): Correctly define explicit
4844 method implementations (they require the full interface name plus
4847 * typemanager.cs: Deply the PtrHashtable here and stop using the
4848 lame keys. Things work so much better.
4850 This of course broke everyone who depended on `RegisterMethod' to
4851 do the `test for existance' test. This has to be done elsewhere.
4853 * support.cs (PtrHashtable): A hashtable that avoid comparing with
4854 the object stupid Equals method (because, that like fails all over
4855 the place). We still do not use it.
4857 * class.cs (TypeContainer.SetRequiredInterface,
4858 TypeContainer.RequireMethods): Killed these two routines and moved
4859 all the functionality to RegisterRequiredImplementations.
4861 (TypeContainer.RegisterRequiredImplementations): This routine now
4862 registers all the implementations required in an array for the
4863 interfaces and abstract methods. We use an array of structures
4864 which can be computed ahead of time to reduce memory usage and we
4865 also assume that lookups are cheap as most classes will not
4866 implement too many interfaces.
4868 We also avoid creating too many MethodSignatures.
4870 (TypeContainer.IsInterfaceMethod): Update and optionally does not
4871 clear the "pending" bit if we find that there are problems with
4874 (TypeContainer.VerifyPendingMethods): Update to report errors of
4875 methods that look like implementations but are not.
4877 (TypeContainer.Define): Add support for explicit interface method
4880 2001-12-12 Miguel de Icaza <miguel@ximian.com>
4882 * typemanager.cs: Keep track of the parameters here instead of
4883 being a feature of the TypeContainer.
4885 * class.cs: Drop the registration of parameters here, as
4886 InterfaceMethods are also interface declarations.
4888 * delegate.cs: Register methods with the TypeManager not only with
4889 the TypeContainer. This code was buggy.
4891 * interface.cs: Full registation here.
4893 2001-12-11 Miguel de Icaza <miguel@ximian.com>
4895 * expression.cs: Remove reducer for binary expressions, it can not
4898 * const.cs: Put here the code that used to go into constant.cs
4900 * constant.cs: Put here the code for constants, this is a new base
4903 * literal.cs: Make Literal derive from Constant.
4905 2001-12-09 Miguel de Icaza <miguel@ximian.com>
4907 * statement.cs (Return.Emit): Report error 157 if the user
4908 attempts to return from a finally block.
4910 (Return.Emit): Instead of emitting a return, jump to the end of
4913 * codegen.cs (EmitContext): ReturnValue, ReturnLabel: new
4914 LocalBuilder to store the result of the function. ReturnLabel is
4915 the target where we jump.
4918 2001-12-09 Radek Doulik <rodo@ximian.com>
4920 * cs-parser.jay: remember alias in current namespace
4922 * ecore.cs (SimpleName::DoResolve): use aliases for types or
4925 * class.cs (LookupAlias): lookup alias in my_namespace
4927 * namespace.cs (UsingAlias): add alias, namespace_or_type pair to
4929 (LookupAlias): lookup alias in this and if needed in parent
4932 2001-12-08 Miguel de Icaza <miguel@ximian.com>
4936 * rootcontext.cs: (ModuleBuilder) Made static, first step into
4937 making things static. I need this to avoid passing the
4938 TypeContainer when calling ParameterType.
4940 * support.cs (InternalParameters.ParameterType): Remove ugly hack
4941 that did string manipulation to compute the type and then call
4942 GetType. Use Parameter.ParameterType instead.
4944 * cs-tokenizer.cs: Consume the suffix for floating values.
4946 * expression.cs (ParameterReference): figure out whether this is a
4947 reference parameter or not. Kill an extra variable by computing
4948 the arg_idx during emission.
4950 * parameter.cs (Parameters.GetParameterInfo): New overloaded
4951 function that returns whether a parameter is an out/ref value or not.
4953 (Parameter.ParameterType): The type of the parameter (base,
4954 without ref/out applied).
4956 (Parameter.Resolve): Perform resolution here.
4957 (Parameter.ExternalType): The full type (with ref/out applied).
4959 * statement.cs (Using.Emit, Using.EmitExpression): Implement
4960 support for expressions on the using statement.
4962 2001-12-07 Miguel de Icaza <miguel@ximian.com>
4964 * statement.cs (Using.EmitLocalVariableDecls): Split the
4965 localvariable handling of the using statement.
4967 (Block.EmitMeta): Keep track of variable count across blocks. We
4968 were reusing slots on separate branches of blocks.
4970 (Try.Emit): Emit the general code block, we were not emitting it.
4972 Check the type of the declaration to be an IDisposable or
4973 something that can be implicity converted to it.
4975 Emit conversions if required.
4977 * ecore.cs (EmptyExpression): New utility class.
4978 (Expression.ImplicitConversionExists): New utility function.
4980 2001-12-06 Miguel de Icaza <miguel@ximian.com>
4982 * statement.cs (Using): Implement.
4984 * expression.cs (LocalVariableReference): Support read only variables.
4986 * statement.cs: Remove the explicit emit for the Leave opcode.
4987 (VariableInfo): Add a readonly field.
4989 2001-12-05 Miguel de Icaza <miguel@ximian.com>
4991 * ecore.cs (ConvCast): new class used to encapsulate the various
4992 explicit integer conversions that works in both checked and
4995 (Expression.ConvertNumericExplicit): Use new ConvCast class to
4996 properly generate the overflow opcodes.
4998 2001-12-04 Miguel de Icaza <miguel@ximian.com>
5000 * statement.cs: The correct type for the EmptyExpression is the
5001 element_type, not the variable type. Ravi pointed this out.
5003 2001-12-04 Ravi Pratap <ravi@ximian.com>
5005 * class.cs (Method::Define): Handle PInvoke methods specially
5006 by using DefinePInvokeMethod instead of the usual one.
5008 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
5009 above to do the task of extracting information and defining the method.
5011 2001-12-04 Ravi Pratap <ravi@ximian.com>
5013 * expression.cs (ArrayCreation::EmitStaticInitializers): Get rid
5014 of the condition for string type.
5016 (Emit): Move that here.
5018 (ArrayCreation::CheckIndices): Keep string literals in their expression
5021 (EmitDynamicInitializers): Handle strings appropriately.
5023 2001-12-04 Miguel de Icaza <miguel@ximian.com>
5025 * codegen.cs (EmitContext): Replace multiple variables with a
5026 single pointer to the current Switch statement.
5028 * statement.cs (GotoDefault, Switch): Adjust to cleaned up
5031 2001-12-03 Miguel de Icaza <miguel@ximian.com>
5035 * statement.cs (GotoDefault), cs-parser.jay: Implement `goto
5038 (Foreach.Emit): Foreach on arrays was not setting
5039 up the loop variables (for break/continue).
5041 (GotoCase): Semi-implented.
5043 2001-12-03 Ravi Pratap <ravi@ximian.com>
5045 * attribute.cs (CheckAttribute): Handle system attributes by using
5046 Attribute.GetAttributes to examine information we need.
5048 (GetValidPlaces): Same here.
5050 * class.cs (Method::Define): Catch invalid use of extern and abstract together.
5052 * typemanager.cs (dllimport_type): Core type for System.DllImportAttribute.
5054 * class.cs (Method.IsPinvoke): Used to determine if we are a PInvoke method.
5056 (Method::Define): Set appropriate flags if we have a DllImport attribute.
5058 (Method::Emit): Handle the case when we are a PInvoke method.
5060 2001-12-03 Miguel de Icaza <miguel@ximian.com>
5062 * expression.cs: Use ResolveWithSimpleName on compound names.
5064 2001-12-02 Ravi Pratap <ravi@ximian.com>
5066 * constant.cs (EmitConstant): Make sure we resolve the associated expression
5067 before trying to reduce it.
5069 * typemanager.cs (RegisterConstant, LookupConstant): Implement.
5071 * constant.cs (LookupConstantValue): Implement.
5073 (EmitConstant): Use the above in emitting the constant.
5075 * expression.cs (MemberAccess::ResolveMemberAccess): Handle constants
5076 that are user-defined by doing a LookupConstantValue on them.
5078 (SimpleName::DoResolve): When we have a FieldExpr, cope with constants
5081 2001-11-29 Miguel de Icaza <miguel@ximian.com>
5083 * expression.cs (BaseAccess, BaseIndexer): Also split this out.
5085 (BaseAccess.DoResolve): Implement.

5255 2001-11-22 Miguel de Icaza <miguel@ximian.com>
5257 * statement.cs (If.Emit): Fix a bug that generated incorrect code
5258 on If. Basically, we have to return `true' (ie, we do return to

5262 short-circuit operators, handle them as short circuit operators.

5265 (Cast.Cast): Take an expression as the target type.
5267 * cs-parser.jay (cast_expression): Remove old hack that only
5268 allowed a limited set of types to be handled. Now we take a
5269 unary_expression and we resolve to a type during semantic
5272 Use the grammar productions from Rhys to handle casts (this is
5273 not complete like Rhys syntax yet, we fail to handle that corner
5274 case that C# has regarding (-x), but we will get there.
5276 2001-11-22 Ravi Pratap <ravi@ximian.com>
5278 * class.cs (EmitFieldInitializer): Take care of the case when we have a
5279 field which is an array type.

5287 * cs-parser.jay (for_statement): Update for array initialization while
5288 declaring variables.
5290 * ecore.cs : The error message was correct, it's the variable's names that

5293 (MemberAccess::DoResolve): Fix the code which handles Enum literals to set
5294 the correct type etc.
5296 (ConvertExplicit): Handle Enum types by examining the underlying type.

5311 BindingFlags.Instance as well
5313 * ecore.cs (Expression.TryImplicitIntConversion): Wrap the result

5318 (Expression.ConvertExplicit): Add explicit type conversions done
5321 (Expression.ImplicitNumericConversion): Oops, forgot to test for
5322 the target type before applying the implicit LongLiterals to ULong
5325 2001-11-21 Miguel de Icaza <miguel@ximian.com>
5327 * cs-parser.jay (for_statement): Reworked the way For works: now
5328 we declare manually any variables that are introduced in
5329 for_initializer to solve the problem of having out-of-band code
5330 emition (that is what got for broken).
5332 (declaration_statement): Perform the actual variable declaration
5333 that used to be done in local_variable_declaration here.
5335 (local_variable_declaration): Do not declare anything, just pass
5336 the information on a DictionaryEntry

5413 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
5414 function used to return a static Parameters structure. Used for
5415 empty parameters, as those are created very frequently.
5417 * cs-parser.jay, class.cs: Use GetEmptyReadOnlyParameters
5419 2001-11-15 Ravi Pratap <ravi@ximian.com>
5421 * interface.cs : Default modifier is private, not public. The

5424 2001-11-15 Ravi Pratap <ravi@ximian.com>
5426 * support.cs (ReflectionParameters): Fix logic to determine
5427 whether the last parameter is a params one. Test 9 passes again.

5433 of $$ to get at the location.
5435 (indexer_declaration): Similar stuff.
5439 * class.cs (Property): Register parameters for the Get and Set methods
5440 if they exist. Test 23 passes again.

5447 IndexOutOfRangeException.
5449 * class.cs (Property::Define): Register property using TypeManager.RegisterProperty

5460 2001-11-09 Miguel de Icaza <miguel@ximian.com>

5486 location where this argument is used. Notice that this is not
5487 part of the "Argument" class as to reduce the size of the
5488 structure (we know the approximate location anyways).

5491 complain with a 206.
5493 (Argument.Emit): Emit addresses of variables.

5524 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
5525 enumerations that are used in heavily used structures derive from

5528 home without adult supervision.
5530 * expression.cs (UnaryMutator): New class, used to handle ++ and
5531 -- separatedly from the other unary operators. Cleans up the
5532 code, and kills the ExpressionStatement dependency in Unary.
5534 (Unary): Removed `method' and `Arguments' from this class, making
5535 it smaller, and moving it all to SimpleCall, so I can reuse this
5536 code in other locations and avoid creating a lot of transient data
5537 strucutres when not required.
5539 * cs-parser.jay: Adjust for new changes.

5612 of a fieldinfo using the above, when dealing with a FieldBuilder.

5775 IStackStore as the order in which arguments are passed reflects
5778 * assign.cs: Instead of using expr.ExprClass to select the way of
5779 assinging, probe for the IStackStore/IAssignMethod interfaces.
5781 * typemanager.cs: Load InitializeArray definition.
5783 * rootcontext.cs (RootContext.MakeStaticData): Used to define

6510 and start performing checks according to the spec.
6512 2001-10-07 Ravi Pratap <ravi@ximian.com>
6514 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
6515 rank_specifiers instead.
6517 (rank_specifiers): Change the order in which the rank specifiers are stored
6519 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
6521 * expression.cs (ElementAccess): Implement the LValue interface too.
6523 2001-10-06 Ravi Pratap <ravi@ximian.com>
6525 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
6526 except that user defined conversions are not included.
6528 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
6529 perform the conversion of the return type, if necessary.
6531 (New::DoResolve): Check whether we are creating an array or an object
6532 and accordingly do the needful.
6534 (New::Emit): Same here.
6536 (New::DoResolve): Implement guts of array creation.

6549 * class.cs: Catch static methods having the flags override,
6550 virtual or abstract.
6552 * expression.cs (UserCast): This user cast was not really doing
6553 what it was supposed to do. Which is to be born in fully resolved
6554 state. Parts of the resolution were being performed at Emit time!
6558 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6560 * expression.cs: Implicity convert the result from UserCast.
6562 2001-10-05 Ravi Pratap <ravi@ximian.com>
6564 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
6565 prevented it from working correctly.

6568 merely ConvertImplicit.
6570 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6572 * typemanager.cs: Make the LookupTypeContainer function static,
6573 and not per-instance.
6575 * class.cs: Make static FindMembers (the one that takes a Type
6578 * codegen.cs: Add EmitForeach here.
6580 * cs-parser.jay: Make foreach a toplevel object instead of the
6581 inline expansion, as we need to perform semantic analysis on it.
6583 2001-10-05 Ravi Pratap <ravi@ximian.com>
6585 * expression.cs (Expression::ImplicitUserConversion): Rename to
6586 UserDefinedConversion.
6588 (Expression::UserDefinedConversion): Take an extra argument specifying
6589 whether we look for explicit user conversions too.

6600 * expression.cs (Cast): Record location info.
6602 (Expression::ConvertExplicit): Take location argument.
6604 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
6605 to determine if we are doing explicit conversions.
6607 (UserCast::Emit): Update accordingly.
6609 (Expression::ConvertExplicit): Report an error if everything fails.
6611 * ../errors/cs0030.cs : Add.
6613 2001-10-04 Miguel de Icaza <miguel@ximian.com>
6615 * modifiers.cs: If the ABSTRACT keyword is present, also set the
6616 virtual and newslot bits.
6618 * class.cs (TypeContainer::RegisterRequiredImplementations):
6619 Record methods we need.
6621 (TypeContainer::MakeKey): Helper function to make keys for
6622 MethodBases, since the Methodbase key is useless.
6624 (TypeContainer::Populate): Call RegisterRequiredImplementations
6625 before defining the methods.
6627 Create a mapping for method_builders_to_methods ahead of time
6628 instead of inside a tight loop.
6630 (::RequireMethods): Accept an object as the data to set into the
6631 hashtable so we can report interface vs abstract method mismatch.
6633 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6635 * report.cs: Make all of it static.
6637 * rootcontext.cs: Drop object_type and value_type computations, as
6638 we have those in the TypeManager anyways.
6640 Drop report instance variable too, now it is a global.
6642 * driver.cs: Use try/catch on command line handling.
6644 Add --probe option to debug the error reporting system with a test
6647 * report.cs: Add support for exiting program when a probe
6648 condition is reached.
6650 2001-10-03 Ravi Pratap <ravi@ximian.com>
6652 * expression.cs (Binary::DoNumericPromotions): Fix the case when
6653 we do a forcible conversion regardless of type, to check if
6654 ForceConversion returns a null.
6656 (Binary::error19): Use location to report error.
6658 (Unary::error23): Use location here too.
6660 * ../errors/cs0019.cs : Check in.
6662 * ../errors/cs0023.cs : Check in.
6664 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
6665 case of a non-null MethodInfo object with a length of 0 !
6667 (Binary::ResolveOperator): Flag error if overload resolution fails to find
6668 an applicable member - according to the spec :-)
6669 Also fix logic to find members in base types.
6671 (Unary::ResolveOperator): Same here.
6673 (Unary::report23): Change name to error23 and make first argument a TypeContainer
6674 as I was getting thoroughly confused between this and error19 :-)
6676 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
6677 (::FindMostEncompassedType): Implement.
6678 (::FindMostEncompassingType): Implement.
6679 (::StandardConversionExists): Implement.
6681 (UserImplicitCast): Re-vamp. We now need info about most specific
6682 source and target types so that we can do the necessary conversions.
6684 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
6685 mathematical union with no duplicates.
6687 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6689 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
6690 in order from base classes to child classes, so that we can in
6691 child classes look up in our parent for method names and
6692 attributes (required for handling abstract, virtual, new, override
6693 constructs: we need to instrospect our base class, and if we dont
6694 populate the classes in order, the introspection might be
6695 incorrect. For example, a method could query its parent before
6696 the parent has any methods and would determine that the parent has
6697 no abstract methods (while it could have had them)).
6699 (RootContext::CreateType): Record the order in which we define the
6702 2001-10-02 Miguel de Icaza <miguel@ximian.com>
6704 * class.cs (TypeContainer::Populate): Also method definitions can
6705 fail now, keep track of this.
6707 (TypeContainer::FindMembers): Implement support for
6708 DeclaredOnly/noDeclaredOnly flag.
6710 (Constructor::Emit) Return the ConstructorBuilder.
6712 (Method::Emit) Return the MethodBuilder.
6713 Check for abstract or virtual methods to be public.
6715 * rootcontext.cs (RootContext::CreateType): Register all the
6716 abstract methods required for the class to be complete and the
6717 interface methods that must be implemented.
6719 * cs-parser.jay: Report error 501 (method requires body if it is
6720 not marked abstract or extern).
6722 * expression.cs (TypeOf::Emit): Implement.
6724 * typemanager.cs: runtime_handle_type, new global type.
6726 * class.cs (Property::Emit): Generate code for properties.
6728 2001-10-02 Ravi Pratap <ravi@ximian.com>
6730 * expression.cs (Unary::ResolveOperator): Find operators on base type
6731 too - we now conform exactly to the spec.
6733 (Binary::ResolveOperator): Same here.
6735 * class.cs (Operator::Define): Fix minor quirk in the tests.
6737 * ../errors/cs0215.cs : Added.
6739 * ../errors/cs0556.cs : Added.
6741 * ../errors/cs0555.cs : Added.
6743 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6745 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
6746 single integer which is really efficient
6748 2001-10-01 Ravi Pratap <ravi@ximian.com>
6750 * expression.cs (Expression::ImplicitUserConversion): Use location
6751 even in the case when we are examining True operators.
6753 * class.cs (Operator::Define): Perform extensive checks to conform
6754 with the rules for operator overloading in the spec.
6756 * expression.cs (Expression::ImplicitReferenceConversion): Implement
6757 some of the other conversions mentioned in the spec.
6759 * typemanager.cs (array_type): New static member for the System.Array built-in
6762 (cloneable_interface): For System.ICloneable interface.
6764 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
6765 we start resolving the tree and populating types.
6767 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
6769 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6771 * expression.cs (Expression::ExprClassFromMemberInfo,
6772 Expression::Literalize): Create literal expressions from
6773 FieldInfos which are literals.
6775 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
6776 type casts, because they were wrong. The test suite in tests
6779 (ImplicitNumericConversion): ushort to ulong requires a widening
6782 Int32 constant to long requires widening cast as well.
6784 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
6785 for integers because the type on the stack is not i4.
6787 2001-09-30 Miguel de Icaza <miguel@ximian.com>
6789 * expression.cs (report118): require location argument.
6791 * parameter.cs: Do not dereference potential null value.
6793 * class.cs: Catch methods that lack the `new' keyword when
6794 overriding a name. Report warnings when `new' is used without
6795 anything being there to override.
6797 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
6799 * class.cs: Only add constructor to hashtable if it is non-null
6800 (as now constructors can fail on define).
6802 (TypeManager, Class, Struct): Take location arguments.
6804 Catch field instance initialization in structs as errors.
6806 accepting_filter: a new filter for FindMembers that is static so
6807 that we dont create an instance per invocation.
6809 (Constructor::Define): Catch errors where a struct constructor is
6812 * cs-parser.jay: Pass location information for various new
6815 * delegate.cs (Delegate): take a location argument.
6817 * driver.cs: Do not call EmitCode if there were problesm in the
6818 Definition of the types, as many Builders wont be there.
6820 * decl.cs (Decl::Decl): Require a location argument.
6822 * cs-tokenizer.cs: Handle properly hex constants that can not fit
6823 into integers, and find the most appropiate integer for it.
6825 * literal.cs: Implement ULongLiteral.
6827 * rootcontext.cs: Provide better information about the location of
6828 failure when CreateType fails.
6830 2001-09-29 Miguel de Icaza <miguel@ximian.com>
6832 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
6835 * expression.cs (Binary::CheckShiftArguments): Add missing type
6837 (Binary::ResolveOperator): Add type to the logical and and logical
6838 or, Bitwise And/Or and Exclusive Or code paths, it was missing
6841 (Binary::DoNumericPromotions): In the case where either argument
6842 is ulong (and most signed types combined with ulong cause an
6843 error) perform implicit integer constant conversions as well.
6845 2001-09-28 Miguel de Icaza <miguel@ximian.com>
6847 * expression.cs (UserImplicitCast): Method should always be
6849 (Invocation::BetterConversion): Simplified test for IntLiteral.
6851 (Expression::ImplicitNumericConversion): Split this routine out.
6852 Put the code that performs implicit constant integer conversions
6855 (Expression::Resolve): Become a wrapper around DoResolve so we can
6856 check eclass and type being set after resolve.
6858 (Invocation::Badness): Remove this dead function
6860 (Binary::ResolveOperator): Do not compute the expensive argumnets
6861 unless we have a union for it.
6863 (Probe::Emit): Is needs to do an isinst and then
6864 compare against null.
6866 (::CanConvert): Added Location argument. If the Location argument
6867 is null (Location.Null), then we do not report errors. This is
6868 used by the `probe' mechanism of the Explicit conversion. We do
6869 not want to generate an error for something that the user
6870 explicitly requested to be casted. But the pipeline for an
6871 explicit cast first tests for potential implicit casts.
6873 So for now, if the Location is null, it means `Probe only' to
6874 avoid adding another argument. Might have to revise this
6877 (ClassCast): New class used to type cast objects into arbitrary
6878 classes (used in Explicit Reference Conversions).
6880 Implement `as' as well.
6882 Reverted all the patches from Ravi below: they were broken:
6884 * The use of `level' as a mechanism to stop recursive
6885 invocations is wrong. That was there just to catch the
6886 bug with a strack trace but not as a way of addressing
6889 To fix the problem we have to *understand* what is going
6890 on and the interactions and come up with a plan, not
6891 just get things going.
6893 * The use of the type conversion cache that I proposed
6894 last night had an open topic: How does this work across
6895 protection domains. A user defined conversion might not
6896 be public in the location where we are applying the
6897 conversion, a different conversion might be selected
6898 (ie, private A->B (better) but public B->A (worse),
6899 inside A, A->B applies, but outside it, B->A will
6902 * On top of that (ie, even if the above is solved),
6903 conversions in a cache need to be abstract. Ie, `To
6904 convert from an Int to a Short use an OpcodeCast', not
6905 `To convert from an Int to a Short use the OpcodeCast on
6906 the variable 5' (which is what this patch was doing).
6908 2001-09-28 Ravi Pratap <ravi@ximian.com>
6910 * expression.cs (Invocation::ConversionExists): Re-write to use
6911 the conversion cache
6913 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
6914 cache all conversions done, not just user-defined ones.
6916 (Invocation::BetterConversion): The real culprit. Use ConversionExists
6917 to determine if a conversion exists instead of acutually trying to
6918 perform the conversion. It's faster too.
6920 (Expression::ConvertExplicit): Modify to use ConversionExists to check
6921 and only then attempt the implicit conversion.
6923 2001-09-28 Ravi Pratap <ravi@ximian.com>
6925 * expression.cs (ConvertImplicit): Use a cache for conversions
6926 already found. Check level of recursion and bail out if necessary.
6928 2001-09-28 Miguel de Icaza <miguel@ximian.com>
6930 * typemanager.cs (string_concat_string_string, string_concat_object_object):
6931 Export standard methods that we expect for string operations.
6933 * statement.cs (Block::UsageWarning): Track usage of variables and
6934 report the errors for not used variables.
6936 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
6939 2001-09-27 Miguel de Icaza <miguel@ximian.com>
6941 * codegen.cs: remove unnneded code
6943 * expression.cs: Removed BuiltinTypeAccess class
6945 Fix the order in which implicit conversions are
6948 The previous fixed dropped support for boxed conversions (adding a
6949 test to the test suite now)
6951 (UserImplicitCast::CanConvert): Remove test for source being null,
6952 that code is broken. We should not feed a null to begin with, if
6953 we do, then we should track the bug where the problem originates
6954 and not try to cover it up here.
6956 Return a resolved expression of type UserImplicitCast on success
6957 rather than true/false. Ravi: this is what I was talking about,
6958 the pattern is to use a static method as a "constructor" for
6961 Also, do not create arguments until the very last minute,
6962 otherwise we always create the arguments even for lookups that
6963 will never be performed.
6965 (UserImplicitCast::Resolve): Eliminate, objects of type
6966 UserImplicitCast are born in a fully resolved state.
6968 * typemanager.cs (InitCoreTypes): Init also value_type
6971 * expression.cs (Cast::Resolve): First resolve the child expression.
6973 (LValue): Add new method AddressOf to be used by
6976 Change the argument of Store to take an EmitContext instead of an
6977 ILGenerator, because things like FieldExpr need to be able to call
6978 their children expression to generate the instance code.
6980 (Expression::Error, Expression::Warning): Sugar functions for
6983 (Expression::MemberLookup): Accept a TypeContainer instead of a
6984 Report as the first argument.
6986 (Expression::ResolvePrimary): Killed. I still want to improve
6987 this as currently the code is just not right.
6989 (Expression::ResolveMemberAccess): Simplify, but it is still
6992 (Unary::Resolve): Catch errors in AddressOf operators.
6994 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
6995 index to a byte for the short-version, or the compiler will choose
6996 the wrong Emit call, which generates the wrong data.
6998 (ParameterReference::Emit, ::Store): same.
7000 (FieldExpr::AddressOf): Implement.
7002 * typemanager.cs: TypeManager: made public variable instead of
7005 * driver.cs: document --fatal.
7007 * report.cs (ErrorMessage, WarningMessage): new names for the old
7008 Error and Warning classes.
7010 * cs-parser.jay (member_access): Turn built-in access to types
7011 into a normal simplename
7013 2001-09-27 Ravi Pratap <ravi@ximian.com>
7015 * expression.cs (Invocation::BetterConversion): Fix to cope
7016 with q being null, since this was introducing a bug.
7018 * expression.cs (ConvertImplicit): Do built-in conversions first.
7020 2001-09-27 Ravi Pratap <ravi@ximian.com>
7022 * expression.cs (UserImplicitCast::Resolve): Fix bug.
7024 2001-09-27 Ravi Pratap <ravi@ximian.com>
7026 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
7027 I had introduced long ago (what's new ?).
7029 * expression.cs (UserImplicitCast::CanConvert): Static method to do
7030 the work of all the checking.
7031 (ConvertImplicit): Call CanConvert and only then create object if necessary.
7032 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
7034 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
7035 that is the right way.
7037 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
7038 overloading resolution. Use everywhere instead of cutting and pasting code.
7040 (Binary::ResolveOperator): Use MakeUnionSet.
7042 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
7043 we have to convert to bool types. Not complete yet.
7045 2001-09-27 Miguel de Icaza <miguel@ximian.com>
7047 * typemanager.cs (TypeManager::CSharpName): support ushort.
7049 * expression.cs (Expression::TryImplicitIntConversion): Attempts
7050 to provide an expression that performsn an implicit constant int
7051 conversion (section 6.1.6).
7052 (Expression::ConvertImplicitRequired): Reworked to include
7053 implicit constant expression conversions.
7055 (Expression::ConvertNumericExplicit): Finished.
7057 (Invocation::Emit): If InstanceExpression is null, then it means
7058 that we perform a call on this.
7060 2001-09-26 Miguel de Icaza <miguel@ximian.com>
7062 * expression.cs (Unary::Emit): Remove some dead code.
7063 (Probe): Implement Resolve and Emit for `is'.
7064 (Expression::ConvertImplicitRequired): Attempt to do constant
7065 expression conversions here. Maybe should be moved to
7066 ConvertImplicit, but I am not sure.
7067 (Expression::ImplicitLongConstantConversionPossible,
7068 Expression::ImplicitIntConstantConversionPossible): New functions
7069 that tell whether is it possible to apply an implicit constant
7070 expression conversion.
7072 (ConvertNumericExplicit): Started work on explicit numeric
7075 * cs-parser.jay: Update operator constants.
7077 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
7078 (Parameters::GetSignature): Hook up VerifyArgs here.
7079 (Parameters::VerifyArgs): Verifies that no two arguments have the
7082 * class.cs (Operator): Update the operator names to reflect the
7083 ones that the spec expects (as we are just stringizing the
7086 * expression.cs (Unary::ResolveOperator): Fix bug: Use
7087 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
7088 previous usage did only work for our methods.
7089 (Expression::ConvertImplicit): Handle decimal implicit numeric
7090 conversions as well.
7091 (Expression::InternalTypeConstructor): Used to invoke constructors
7092 on internal types for default promotions.
7094 (Unary::Emit): Implement special handling for the pre/post
7095 increment/decrement for overloaded operators, as they need to have
7096 the same semantics as the other operators.
7098 (Binary::ResolveOperator): ditto.
7099 (Invocation::ConversionExists): ditto.
7100 (UserImplicitCast::Resolve): ditto.
7102 2001-09-26 Ravi Pratap <ravi@ximian.com>
7104 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded
7105 operator, return after emitting body. Regression tests pass again !
7107 * expression.cs (ConvertImplicit): Take TypeContainer as first argument
7108 (Unary::ForceConversion, Binary::ForceConversion): Ditto.
7109 (Invocation::OverloadResolve): Ditto.
7110 (Invocation::BetterFunction, BetterConversion, ConversionExists): Ditto.
7112 * everywhere : update calls to the above methods accordingly.
7114 2001-09-26 Miguel de Icaza <miguel@ximian.com>
7116 * assign.cs (Assign): Make it inherit from ExpressionStatement.
7118 * expression.cs (ExpressionStatement): New base class used for
7119 expressions that can appear in statements, so that we can provide
7120 an alternate path to generate expression that do not leave a value
7123 (Expression::Emit, and all the derivatives): We no longer return
7124 whether a value is left on the stack or not. Every expression
7125 after being emitted leaves a single value on the stack.
7127 * codegen.cs (EmitContext::EmitStatementExpression): Use the
7128 facilties of ExpressionStatement if possible.
7130 * cs-parser.jay: Update statement_expression.

7134 * driver.cs: Change the wording of message
7136 2001-09-25 Ravi Pratap <ravi@ximian.com>
7138 * expression.cs (Binary::ResolveOperator): Had forgottten to set
7139 the type of the expression to the return type of the method if
7140 we have an overloaded operator match ! The regression tests pass again !
7141 (Unary::ResolveOperator): Ditto.
7143 * expression.cs (Invocation::ConversionExists): Correct the member lookup
7144 to find "op_Implicit", not "implicit" ;-)
7145 (UserImplicitCast): New class to take care of user-defined implicit conversions.
7146 (ConvertImplicit, ForceConversion): Take TypeContainer argument
7148 * everywhere : Correct calls to the above accordingly.
7150 * expression.cs (UserImplicitCast::Resolve, ::Emit): Implement.
7151 (ConvertImplicit): Do user-defined conversion if it exists.
7153 2001-09-24 Miguel de Icaza <miguel@ximian.com>
7155 * assign.cs: track location.
7156 (Resolve): Use implicit conversions on assignment.
7158 * literal.cs: Oops. Not good, Emit of short access values should
7159 pass (Bytes) or the wrong argument will be selected.
7161 * expression.cs (Unary::Emit): Emit code for -expr.
7163 (Unary::ResolveOperator): Handle `Substract' for non-constants
7164 (substract from zero from the non-constants).
7165 Deal with Doubles as well.
7167 (Expression::ConvertImplicitRequired): New routine that reports an
7168 error if no implicit conversion exists.

7221 * typemanager.cs: declare and load enum_type, delegate_type and
7224 * expression.cs (Expression::Emit): Now emit returns a value that
7225 tells whether a value is left on the stack or not. This strategy
7226 might be reveted tomorrow with a mechanism that would address
7227 multiple assignments.

7279 * expression.cs: Instead of having FIXMEs in the Resolve
7280 functions, throw exceptions so it is obvious that we are facing a
7283 * cs-parser.jay (invocation_expression): Pass Location information.
7285 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
7286 Use a basename for those routines because .NET does not like paths

7301 expressions (otherwise they are Unary {Literal}).
7302 (Invocation::Badness): Take into account `Implicit constant
7303 expression conversions'.
7305 * literal.cs (LongLiteral): Implement long literal class.
7306 (IntLiteral): export the `Value' of the intliteral.
7308 2001-09-19 Ravi Pratap <ravi@ximian.com>

7323 * expression.cs (Unary::Resolve): Implement.
7324 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
7325 operators are found instead of making noise ;-)
7326 (Unary::ResolveOperator): New method to do precisely the same thing which
7327 Binary::ResolveOperator does for Binary expressions.
7328 (Unary.method, .Arguments): Add.
7329 (Unary::OperName): Implement.
7330 (Unary::ForceConversion): Copy and Paste !
7332 * class.cs (Operator::Define): Fix a small bug for the case when we have
7335 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
7336 for the inbuilt operators. Only overloading works for now ;-)
7338 2001-09-18 Miguel de Icaza <miguel@ximian.com>
7340 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
7341 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

7354 (FieldExpr::Emit): Implement.
7356 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
7357 the last instruction contains a return opcode to avoid generating
7358 the last `ret' instruction (this generates correct code, and it is
7359 nice to pass the peverify output).
7361 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
7362 initializer for static and instance variables.
7363 (Constructor::Emit): Allow initializer to be null in the case of
7364 static constructors. Only emit initializer for instance
7367 (TypeContainer::FindMembers): Return a null array if there are no
7370 Also fix the code for the MemberTypes.Method branch, as it was not
7371 scanning that for operators (or tried to access null variables before).
7373 * assign.cs (Assign::Emit): Handle instance and static fields.
7377 * driver.cs: Stop compilation if there are parse errors.
7379 * cs-parser.jay (constructor_declaration): Provide default base
7380 initializer for non-static constructors.
7381 (constructor_declarator): Do not provide a default base
7382 initializers if none was specified.
7383 Catch the fact that constructors should not have parameters.
7385 * class.cs: Do not emit parent class initializers for static
7386 constructors, that should be flagged as an error.
7388 2001-09-18 Ravi Pratap <ravi@ximian.com>
7390 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
7391 Move back code into TypeContainer::Populate.

7417 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
7420 (Expression::MemberLookup): Provide a version that allows to
7421 specify the MemberTypes and BindingFlags.
7423 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
7424 so it was not fetching variable information from outer blocks.
7426 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
7427 Beforefieldinit as it was buggy.
7429 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
7432 * class.cs (Constructor::Emit): Only emit if block is not null.
7433 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
7434 deal with this by semantically definining it as if the user had
7437 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
7438 constructors as we now "emit" them at a higher level.

7445 * expression.cs: Cast to ConstructorInfo instead of MethodInfo

7465 and Unary::Operator.
7467 * cs-parser.jay (operator_declaration, CheckBinaryOperator, CheckUnaryOperator): Update

7476 (TypeContainer::Emit): Emit the operators we have too.
7478 * expression.cs (Binary::Emit): Update to emit the appropriate code for

7485 2001-09-16 Ravi Pratap <ravi@ximian.com>

7508 * cs-parser.jay (namespace_declaration): Call RecordNamespace to
7511 * rootcontext.cs (IsNamespace): Fixed it :-)
7513 2001-09-14 Miguel de Icaza <miguel@ximian.com>
7515 * class.cs (TypeContainer::FindMembers): Add support for
7517 (MethodCore): New class that encapsulates both the shared aspects
7518 of a Constructor and a Method.

7522 Load System assembly as well as part of the standard library.
7524 * report.cs: Allow throwing exceptions on errors for debugging.
7526 * modifiers.cs: Do not use `parent', instead use the real type
7527 container to evaluate permission settings.
7529 * class.cs: Put Ravi's patch back in. He is right, and we will
7530 have to cope with the
7532 2001-09-14 Ravi Pratap <ravi@ximian.com>
7534 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
7535 FamORAssem, not FamANDAssem.

7539 * driver.cs: Added --parse option that only parses its input files
7542 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
7543 incorrect. IsTopLevel is not used to tell whether an object is
7544 root_types or not (that can be achieved by testing this ==
7545 root_types). But to see if this is a top-level *class* (not
7546 necessarly our "toplevel" container).
7548 2001-09-14 Ravi Pratap <ravi@ximian.com>
7550 * enum.cs (Enum::Define): Modify to call the Lookup method on the
7551 parent instead of a direct call to GetType.
7553 2001-09-14 Ravi Pratap <ravi@ximian.com>
7555 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
7556 Modifiers.TypeAttr. This should just be a call to that method.
7558 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
7559 object so that we can determine if we are top-level or not.
7561 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
7564 * enum.cs (Enum::Define): Ditto.
7566 * modifiers.cs (FieldAttr): Re-write.
7568 * class.cs (TypeContainer::IsTopLevel): Change accessibility to public.
7569 (TypeContainer::HaveStaticConstructor): New property to provide access
7570 to precisely that info.
7572 * modifiers.cs (MethodAttr): Re-write.
7573 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
7575 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
7576 of top-level types as claimed.
7578 2001-09-13 Miguel de Icaza <miguel@ximian.com>
7580 * expression.cs (MemberLookup): Fruitless attempt to lookup
7581 constructors. Maybe I need to emit default constructors? That
7582 might be it (currently .NET emits this for me automatically).
7583 (Invocation::OverloadResolve): Cope with Arguments == null.
7584 (Invocation::EmitArguments): new function, shared by the new
7586 (Invocation::Emit): Handle static and instance methods. Emit
7587 proper call instruction for virtual or non-virtual invocations.

7598 SimpleLookup): Auxiliary routines to help parse a qualifier
7601 Update qualifier_identifier rule.
7603 * codegen.cs: Removed debugging messages.
7605 * class.cs: Make this a global thing, this acts just as a "key" to
7606 objects that we might have around.
7608 (Populate): Only initialize method_builders_to_methods once.
7610 * expression.cs (PropertyExpr): Initialize type from the
7613 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
7614 Resolve pattern. Attempt to implicitly convert value to boolean.
7617 * expression.cs: Set the type for the int32/int32 argument case.
7618 (Binary::ResolveOperator): Set the return type to boolean for
7619 comparission operators
7621 * typemanager.cs: Remove debugging print code.
7623 (Invocation::Resolve): resolve type.
7625 * class.cs: Allocate a MemberInfo of the correct size, as the code
7626 elsewhere depends on the test to reflect the correct contents.
7628 (Method::) Keep track of parameters, due to System.Reflection holes
7630 (TypeContainer::Populate): Keep track of MethodBuilders to Method
7633 (TypeContainer::FindMembers): Use ArrayList and then copy an array
7634 of the exact size and return that.
7636 (Class::LookupMethodByBuilder): New function that maps
7637 MethodBuilders to its methods. Required to locate the information
7638 on methods because System.Reflection bit us again.
7640 * support.cs: New file, contains an interface ParameterData and
7641 two implementations: ReflectionParameters and InternalParameters
7642 used to access Parameter information. We will need to grow this
7645 * expression.cs (Invocation::GetParameterData): implement a cache
7646 and a wrapper around the ParameterData creation for methods.
7647 (Invocation::OverloadResolve): Use new code.
7649 2001-09-13 Ravi Pratap <ravi@ximian.com>
7651 * class.cs (TypeContainer::EmitField): Remove and move into
7652 (Field::Define): here and modify accordingly.
7653 (Field.FieldBuilder): New member.
7654 (TypeContainer::Populate): Update accordingly.
7655 (TypeContainer::FindMembers): Implement.
7657 2001-09-13 Miguel de Icaza <miguel@ximian.com>
7659 * statement.cs: (VariableInfo::VariableType): New field to be
7660 initialized with the full type once it is resolved.
7662 2001-09-12 Miguel de Icaza <miguel@ximian.com>
7664 * parameter.cs (GetParameterInfo): Use a type cache to compute
7665 things only once, and to reuse this information

7668 (OpcodeCast::Emit): fix.
7670 (ParameterReference::Resolve): Implement.
7671 (ParameterReference::Emit): Implement.
7673 * cs-parser.jay: Fix bug introduced by Ravi, variable initializers

7703 2001-09-12 Ravi Pratap <ravi@ximian.com>
7705 * class.cs (TypeContainer::FindMembers): Method which does exactly
7706 what Type.FindMembers does, only we don't have to use reflection. No
7709 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
7710 typecontainer objects as we need to get at them.
7711 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.
7713 * rootcontext.cs : Correspondingly modify called to AddUserType to pass the
7714 typecontainer object.
7716 * expression.cs (MemberLookup): Modify signature to take a RootContext object instead
7717 of just a Report object.
7719 2001-09-11 Ravi Pratap <ravi@ximian.com>

7738 (Event::Define): Ditto.
7739 (Property::Define): Ditto.
7741 2001-09-10 Ravi Pratap <ravi@ximian.com>
7743 * class.cs (TypeContainer::Populate): Now define operators too.
7744 (TypeContainer.Operators): New property to access the list of operators
7746 (Operator.OperatorMethodBuilder): New member to hold the method builder
7747 for the operator we are defining.
7748 (Operator::Define): Implement.
7750 2001-09-10 Ravi Pratap <ravi@ximian.com>
7752 * class.cs (Event::Define): Make the prefixes of the accessor methods
7753 addOn_ and removeOn_
7755 * genericparser.cs (GenericParser::error): Overloaded method to handle the case
7756 of the location being passed in too. Ideally, this should go later since all
7757 error reporting should be done through the Report object.

7768 my previous implementation, did not work.
7770 * typemanager.cs: Add a couple of missing types (the longs).
7772 * literal.cs: Use TypeManager.bool_type instead of getting it.

7802 (CheckBinaryOperator): Same here.
7804 * rootcontext.cs (LookupType): Add an extra lookup which simply does a lookup
7805 on the name without any prefixes of namespace names etc. This is because we
7806 already might have something already fully qualified like
7807 'System.Console.WriteLine'

7811 2001-09-07 Ravi Pratap <ravi@ximian.com>

8134 and re-write the code in the actions to extract the specific and
8135 general catch clauses by being a little smart ;-)
8137 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
8138 Hooray, try and catch statements parse fine !

8142 * statement.cs (Block::GetVariableType): Fix logic to extract the type
8143 string from the hashtable of variables.
8145 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did

8147 (catch_clauses): Fixed gross error which made Key and Value of the
8148 DictionaryEntry the same : $1 !!
8150 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
8152 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
8154 * cs-parser.jay (event_declaration): Correct to remove the semicolon

8161 (indexer_declarator): Implement actions.
8162 (parsing_indexer): New local boolean used to keep track of whether

8190 concatenating all the commas together, just as they appear.
8191 (opt_dim_separators): Modify accordingly

8196 instead of ignoring the rank_specifiers.
8197 (expression_list): Implement to collect the expressions

8223 * typemanager.cs (InitCoreTypes): Initialize the various core
8224 types after we have populated the type manager with the user
8225 defined types (this distinction will be important later while
8226 compiling corlib.dll)
8228 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
8229 on Expression Classification. Now all expressions have a method
8230 `Resolve' and a method `Emit'.
8232 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
8233 generation from working. Also add some temporary debugging
8236 2001-08-24 Miguel de Icaza <miguel@ximian.com>
8238 * codegen.cs: Lots of code generation pieces. This is only the
8239 beginning, will continue tomorrow with more touches of polish. We

8247 emission to keep a context. Most of the code generation will be

8270 move from Properties to public readonly fields.
8271 (Method::ParameterTypes): Returns the parameter types for the
8272 function, and implements a cache that will be useful later when I
8273 do error checking and the semantic analysis on the methods is
8275 (Constructor::GetCallingConvention): Renamed from CallingConvetion
8276 and made a method, optional argument tells whether this is a class
8277 or a structure to apply the `has-this' bit.

8280 (Method::Define): Defines the type, a second pass is performed
8281 later to populate the methods.

8303 and the default static constructor.
8305 (Constructor::) Another class that starts using `public readonly'
8306 instead of properties.

8310 (Field::) use readonly public fields instead of properties also.
8312 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
8313 track of static constructors; If none is used, turn on
8314 BeforeFieldInit in the TypeAttributes.
8316 * cs-parser.jay (opt_argument_list): now the return can be null
8317 for the cases where there are no arguments.
8319 (constructor_declarator): If there is no implicit `base' or

8322 * modifiers.cs (MethodAttr): New static function maps a set of
8323 modifiers flags into a MethodAttributes enum
8324 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
8325 MethodAttr, TypeAttr to represent the various mappings where the
8327 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
8329 2001-08-19 Miguel de Icaza <miguel@ximian.com>

8350 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
8351 initialize their hashtables/arraylists only when they are needed
8352 instead of doing this always.
8354 * parameter.cs: Handle refs and out parameters.
8356 * cs-parser.jay: Use an ArrayList to construct the arguments
8357 instead of the ParameterCollection, and then cast that to a
8360 * parameter.cs: Drop the use of ParameterCollection and use
8361 instead arrays of Parameters.
8363 (GetParameterInfo): Use the Type, not the Name when resolving
8366 2001-08-13 Miguel de Icaza <miguel@ximian.com>

8383 this System.Reflection code is. Kudos to Microsoft
8385 * typemanager.cs: Implement a type cache and avoid loading all
8386 types at boot time. Wrap in LookupType the internals. This made
8387 the compiler so much faster. Wow. I rule!
8389 * driver.cs: Make sure we always load mscorlib first (for
8390 debugging purposes, nothing really important).
8392 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
8393 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
8395 * rootcontext.cs: Lookup types on their namespace; Lookup types
8396 on namespaces that have been imported using the `using' keyword.
8398 * class.cs (TypeContainer::TypeAttr): Virtualize.
8399 (Class::TypeAttr): Return attributes suitable for this bad boy.
8400 (Struct::TypeAttr): ditto.

8439 2001-08-03 Miguel de Icaza <miguel@ximian.com>
8441 * rootcontext.cs: Provide better error reporting.
8443 * cs-parser.jay (interface_base): set our $$ to be interfaces.
8445 * rootcontext.cs (CreateInterface): Handle the case where there
8446 are no parent interfaces.
8448 (CloseTypes): Routine to flush types at the end.
8449 (CreateInterface): Track types.
8450 (GetInterfaces): Returns an array of Types from the list of
8453 * typemanager.c (AddUserType): Mechanism to track user types (puts
8454 the type on the global type hash, and allows us to close it at the
8457 2001-08-02 Miguel de Icaza <miguel@ximian.com>
8459 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
8460 RecordInterface instead.
8462 * cs-parser.jay: Updated to reflect changes above.
8464 * decl.cs (Definition): Keep track of the TypeBuilder type that
8465 represents this type here. Not sure we will use it in the long
8466 run, but wont hurt for now.
8468 * driver.cs: Smaller changes to accomodate the new code.
8470 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
8473 * rootcontext.cs (CreateInterface): New method, used to create
8474 the System.TypeBuilder type for interfaces.
8475 (ResolveInterfaces): new entry point to resolve the interface
8477 (CodeGen): Property, used to keep track of the code generator.
8479 2001-07-26 Miguel de Icaza <miguel@ximian.com>
8481 * cs-parser.jay: Add a second production for delegate_declaration
8484 (enum_body): Put an opt_comma here instead of putting it on
8485 enum_body or enum_member_declarations so we can handle trailing
8486 commas on enumeration members. Gets rid of a shift/reduce.
8488 (type_list): Need a COMMA in the middle.
8490 (indexer_declaration): Tell tokenizer to recognize get/set
8492 * Remove old targets.
8494 * Re-add the parser target.
8496 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8498 * cs-parser.jay: Add precendence rules for a number of operators
8499 ot reduce the number of shift/reduce conflicts in the grammar.
8501 2001-07-17 Miguel de Icaza <miguel@ximian.com>
8503 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
8506 Get rid of old crufty code.
8508 * rootcontext.cs: Use this to keep track of the parsed
8509 representation and the defined types available to the program.
8511 * gen-treedump.cs: adjust for new convention.
8513 * type.cs: Split out the type manager, and the assembly builder
8516 * typemanager.cs: the type manager will live here now.
8518 * cil-codegen.cs: And the code generator here.
8520 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
8522 * makefile: Fixed up for easy making.
8524 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8526 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
8529 (unary_expression): Expand pre_increment_expression and
8530 post_decrement_expression to reduce a shift/reduce.
8532 2001-07-11 Simon Cozens
8534 * cs-tokenizer.cs: Hex numbers should begin with a 0.
8536 Improve allow_keyword_as_indent name.
8538 2001-06-19 Miguel de Icaza <miguel@ximian.com>
8540 * Adjustments for Beta2.
8542 2001-06-13 Miguel de Icaza <miguel@ximian.com>
8544 * decl.cs: Added `Define' abstract method.
8545 (InTransit): new property, used to catch recursive definitions.
8547 * interface.cs: Implement `Define'.
8549 * modifiers.cs: Map Modifiers.constants to
8550 System.Reflection.TypeAttribute flags.
8552 * class.cs: Keep track of types and user-defined types.
8553 (BuilderInit): New method for creating an assembly
8554 (ResolveType): New function to launch the resolution process, only
8555 used by interfaces for now.
8557 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
8558 that are inserted into the name space.
8560 2001-06-08 Miguel de Icaza <miguel@ximian.com>
8562 * ARGH. I have screwed up my tree so many times due to the use of
8563 rsync rather than using CVS. Going to fix this at once.
8565 * driver.cs: Objetify driver. Load assemblies, use assemblies to
8568 2001-06-07 Miguel de Icaza <miguel@ximian.com>
8570 * Experiment successful: Use System.Type rather that our own
8573 2001-05-25 Miguel de Icaza <miguel@ximian.com>
8575 * cs-parser.jay: Removed nsAliases from here.
8577 Use new namespaces, handle `using XXX;'
8579 * namespace.cs: Reimplemented namespace handling, use a recursive
8580 definition of the class. Now we can keep track of using clauses
8581 and catch invalid using clauses.
8583 2001-05-24 Miguel de Icaza <miguel@ximian.com>
8585 * gen-treedump.cs: Adapted for all the renaming.
8587 * expression.cs (Expression): this class now has a Type property
8588 which returns an expression Type.
8590 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
8591 `Type', as this has a different meaning now in the base
8593 2001-05-22 Miguel de Icaza <miguel@ximian.com>
8595 * interface.cs, class.cs: Removed from all the sources the
8596 references to signature computation, as we can not do method
8597 signature computation during the parsing time, as we are not
8598 trying to solve at that point distinguishing:
8602 void a (NS.Blah x) {}
8605 Which depending on the context might be valid or not, as we do not
8606 know if Blah is the same thing as NS.Blah at that point.
8608 * Redid everything so the code uses TypeRefs now instead of
8609 Types. TypeRefs are just temporary type placeholders, that need
8610 to be resolved. They initially have a pointer to a string and the
8611 current scope in which they are used. This is used later by the
8612 compiler to resolve the reference to an actual Type.
8614 * DeclSpace is no longer a CIR.Type, and neither are
8615 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
8616 are all DeclSpaces, but no Types.
8618 * type.cs (TypeRefManager): This implements the TypeRef manager,
8619 which keeps track of all the types that need to be resolved after
8620 the parsing has finished.
8622 2001-05-13 Miguel de Icaza <miguel@ximian.com>
8624 * ARGH. We are going to have to store `foreach' as a class rather
8625 than resolving it, as we need to verify error 1579 after name
8626 resolution. *OR* we could keep a flag that says `This request to
8627 IEnumerator comes from a foreach statement' which we can then use
8628 to generate the error.
8630 2001-05-10 Miguel de Icaza <miguel@ximian.com>
8632 * class.cs (TypeContainer.AddMethod): we now add methods to the
8633 MethodGroup instead of the method hashtable.
8635 * expression.cs: Add MethodGroup abstraction, which gets us one
8636 step closer to the specification in the way we handle method
8639 * cs-parser.jay (primary_expression): qualified_identifier now
8640 tried to match up an identifier to a local variable reference or
8641 to a parameter reference.
8643 current_local_parameters is now a parser global variable that
8644 points to the current parameters for the block, used during name
8647 (property_declaration): Now creates an implicit `value' argument to
8650 2001-05-09 Miguel de Icaza <miguel@ximian.com>
8652 * parameter.cs: Do not use `param' arguments as part of the
8653 signature, per the spec.
8655 2001-05-08 Miguel de Icaza <miguel@ximian.com>
8657 * decl.cs: Base class for classes, structs and interfaces. This
8658 is the "Declaration Space"
8660 * cs-parser.jay: Use CheckDef for checking declaration errors
8661 instead of having one on each function.
8663 * class.cs: Factor out some code for handling error handling in
8664 accordance to the "Declarations" section in the "Basic Concepts"
8665 chapter in the ECMA C# spec.
8667 * interface.cs: Make all interface member classes derive from
8668 InterfaceMemberBase.
8670 2001-05-07 Miguel de Icaza <miguel@ximian.com>
8672 * Many things: all interfaces are parsed and generated in
8673 gen-treedump. Support for member variables, constructors,
8674 destructors, properties, constants is there.
8676 Beginning of the IL backend, but very little done, just there for
8679 2001-04-29 Miguel de Icaza <miguel@ximian.com>
8681 * cs-parser.jay: Fix labeled statement.
8683 * cs-tokenizer.cs (escape): Escape " and ' always.
8684 ref_line, ref_name: keep track of the line/filename as instructed
8685 by #line by the compiler.
8688 2001-04-27 Miguel de Icaza <miguel@ximian.com>
8690 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
8691 to match the values in System.CodeDOM.
8693 Divid renamed to Divide.
8695 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
8697 (Statements.set): remove.
8699 * System.CodeDOM/CodeCatchClause.cs: always have a valid
8702 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
8703 falseStatements always have valid values.
8705 * cs-parser.jay: Use System.CodeDOM now.
