3 * delegate.cs (Delegate::VerifyDelegate): New method to verify
4 if two delegates are compatible.

7 we instantiate a delegate from another delegate.
9 * typemanager.cs (FindMembers): Don't even try to look up members
10 of Delegate types for now.
12 2001-10-18 Ravi Pratap <ravi@ximian.com>
14 * delegate.cs (NewDelegate): New class to take care of delegate

65 * typemanager.cs (AddDelegateType): Store a pointer to the Delegate class
68 * delegate.cs (ConstructorBuilder, InvokeBuilder, ...): New members to hold

91 loop and end of the loop).
93 2001-10-15 Ravi Pratap <ravi@ximian.com>
95 * delegate.cs (Emit): Get rid of it as there doesn't seem to be any ostensible

119 how to take care of the native int bit :-(
121 * cs-parser.jay (delegate_declaration): Fixed the bug that I had introduced :-)
122 Qualify the name of the delegate, not its return type !
124 * expression.cs (ImplicitReferenceConversion): Implement guts of implicit array
127 (StandardConversionExists): Checking for array types turns out to be recursive.
129 (ConvertReferenceExplicit): Implement array conversion.
131 (ExplicitReferenceConversionExists): New method to determine precisely that :-)
133 2001-10-12 Ravi Pratap <ravi@ximian.com>
135 * cs-parser.jay (delegate_declaration): Store the fully qualified
136 name as it is a type declaration.
138 * delegate.cs (ReturnType, Name): Rename members to these. Make them

142 as TypeContainer::DefineType.
144 (Populate): Method in which all the definition of the various methods (Invoke)
147 (Emit): Emit any code, if necessary. I am not sure about this really, but let's

167 a few more explicit conversions.
169 * modifiers.cs: `NEW' modifier maps to HideBySig.

194 (This::LValueResolve): Implement.
196 (This::Store): Remove warning, assigning to `this' in structures
199 (Invocation::Emit): Deal with invocation of
200 methods on value types. We need to pass the address to structure
201 methods rather than the object itself. (The equivalent code to
202 emit "this" for structures leaves the entire structure on the
203 stack instead of a pointer to it).
205 (ParameterReference::DoResolve): Compute the real index for the
206 argument based on whether the method takes or not a `this' pointer
207 (ie, the method is static).
209 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store

216 * class.cs (TypeContainer::DefineType): Method to actually do the business of
217 defining the type in the Modulebuilder or Typebuilder. This is to take
218 care of nested types which need to be defined on the TypeBuilder using
221 (TypeContainer::GetClassBases): Implement. Essentially the code from the
222 methods in RootContext, only ported to be part of TypeContainer.
224 (TypeContainer::GetInterfaceOrClass): Ditto.
226 (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
228 * interface.cs (Interface::DefineInterface): New method. Does exactly
229 what RootContext.CreateInterface did earlier, only it takes care of nested types
232 (Interface::GetInterfaces): Move from RootContext here and port.
234 (Interface::GetInterfaceByName): Same here.
236 * rootcontext.cs (ResolveTree): Re-write.

240 * class.cs (TypeContainer::Populate): Populate nested types too.
241 (TypeContainer::Emit): Emit nested members too.
243 * typemanager.cs (AddUserType): Do not make use of the FullName property,
244 instead just use the name argument passed in as it is already fully
247 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
248 to TypeContainer mapping to see if a type is user-defined.
250 * class.cs (TypeContainer::CloseType): Implement.
252 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
253 the default constructor.
255 (TypeContainer::Populate): Fix minor bug which led to creating default constructors

277 as a source to convert to any reference type.
279 * statement.cs (Return): Perform any implicit conversions to
280 expected return type.
282 Validate use of return statement.
284 * codegen.cs (EmitContext): Pass the expected return type here.
286 * class.cs (Method, Constructor, Property): Pass expected return
289 2001-10-09 Miguel de Icaza <miguel@ximian.com>
291 * expression.cs: Make DoResolve take an EmitContext instead of a
294 Replaced `l' and `location' for `loc', for consistency.
296 (Error, Warning): Remove unneeded Tc argument.
298 * assign.cs, literal.cs, constant.cs: Update to new calling
301 * codegen.cs: EmitContext now contains a flag indicating whether
302 code is being generated in a static method or not.
304 * cs-parser.jay: DecomposeQI, new function that replaces the old
305 QualifiedIdentifier. Now we always decompose the assembled
306 strings from qualified_identifier productions into a group of
309 2001-10-08 Miguel de Icaza <miguel@ximian.com>
311 * rootcontext.cs: Deal with field-less struct types correctly now
312 by passing the size option to Define Type.
314 * class.cs: Removed hack that created one static field.
316 2001-10-07 Miguel de Icaza <miguel@ximian.com>
318 * statement.cs: Moved most of the code generation here.
320 2001-10-09 Ravi Pratap <ravi@ximian.com>
322 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
325 (ElementAccess): Remove useless bits for now - keep checks as the spec
328 2001-10-08 Ravi Pratap <ravi@ximian.com>
330 * expression.cs (ElementAccess::DoResolve): Remove my crap code
331 and start performing checks according to the spec.
333 2001-10-07 Ravi Pratap <ravi@ximian.com>
335 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
336 rank_specifiers instead.
338 (rank_specifiers): Change the order in which the rank specifiers are stored
340 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
342 * expression.cs (ElementAccess): Implement the LValue interface too.
344 2001-10-06 Ravi Pratap <ravi@ximian.com>
346 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit

349 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
350 perform the conversion of the return type, if necessary.
352 (New::DoResolve): Check whether we are creating an array or an object
353 and accordingly do the needful.

368 * cs-parser.jay: Added support for try/catch/finalize.
370 * class.cs: Catch static methods having the flags override,
373 * expression.cs (UserCast): This user cast was not really doing
374 what it was supposed to do. Which is to be born in fully resolved
375 state. Parts of the resolution were being performed at Emit time!
379 2001-10-05 Miguel de Icaza <miguel@ximian.com>
381 * expression.cs: Implicity convert the result from UserCast.
383 2001-10-05 Ravi Pratap <ravi@ximian.com>
385 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
386 prevented it from working correctly.

399 * codegen.cs: Add EmitForeach here.
401 * cs-parser.jay: Make foreach a toplevel object instead of the

412 (Expression::ImplicitUserConversion): Make it a call to UserDefinedConversion.
414 (UserDefinedConversion): Incorporate support for user defined explicit conversions.
416 (ExplicitUserConversion): Make it a call to UserDefinedConversion
417 with the appropriate arguments.
419 * cs-parser.jay (cast_expression): Record location too.
421 * expression.cs (Cast): Record location info.
423 (Expression::ConvertExplicit): Take location argument.
425 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
426 to determine if we are doing explicit conversions.
428 (UserCast::Emit): Update accordingly.
430 (Expression::ConvertExplicit): Report an error if everything fails.
432 * ../errors/cs0030.cs : Add.
434 2001-10-04 Miguel de Icaza <miguel@ximian.com>
436 * modifiers.cs: If the ABSTRACT keyword is present, also set the
437 virtual and newslot bits.
439 * class.cs (TypeContainer::RegisterRequiredImplementations):
440 Record methods we need.
442 (TypeContainer::MakeKey): Helper function to make keys for
443 MethodBases, since the Methodbase key is useless.
445 (TypeContainer::Populate): Call RegisterRequiredImplementations
446 before defining the methods.
448 Create a mapping for method_builders_to_methods ahead of time
449 instead of inside a tight loop.
451 (::RequireMethods): Accept an object as the data to set into the
452 hashtable so we can report interface vs abstract method mismatch.
454 2001-10-03 Miguel de Icaza <miguel@ximian.com>
456 * report.cs: Make all of it static.
458 * rootcontext.cs: Drop object_type and value_type computations, as
459 we have those in the TypeManager anyways.
461 Drop report instance variable too, now it is a global.
463 * driver.cs: Use try/catch on command line handling.
465 Add --probe option to debug the error reporting system with a test
468 * report.cs: Add support for exiting program when a probe
469 condition is reached.
471 2001-10-03 Ravi Pratap <ravi@ximian.com>
473 * expression.cs (Binary::DoNumericPromotions): Fix the case when
474 we do a forcible conversion regardless of type, to check if
475 ForceConversion returns a null.
477 (Binary::error19): Use location to report error.
479 (Unary::error23): Use location here too.
481 * ../errors/cs0019.cs : Check in.
483 * ../errors/cs0023.cs : Check in.
485 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
486 case of a non-null MethodInfo object with a length of 0 !
488 (Binary::ResolveOperator): Flag error if overload resolution fails to find
489 an applicable member - according to the spec :-)
490 Also fix logic to find members in base types.
492 (Unary::ResolveOperator): Same here.
494 (Unary::report23): Change name to error23 and make first argument a TypeContainer
495 as I was getting thoroughly confused between this and error19 :-)
497 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
498 (::FindMostEncompassedType): Implement.
499 (::FindMostEncompassingType): Implement.
500 (::StandardConversionExists): Implement.
502 (UserImplicitCast): Re-vamp. We now need info about most specific
503 source and target types so that we can do the necessary conversions.
505 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
506 mathematical union with no duplicates.
508 2001-10-03 Miguel de Icaza <miguel@ximian.com>
510 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
511 in order from base classes to child classes, so that we can in
512 child classes look up in our parent for method names and
513 attributes (required for handling abstract, virtual, new, override
514 constructs: we need to instrospect our base class, and if we dont
515 populate the classes in order, the introspection might be
516 incorrect. For example, a method could query its parent before
517 the parent has any methods and would determine that the parent has
518 no abstract methods (while it could have had them)).
520 (RootContext::CreateType): Record the order in which we define the
523 2001-10-02 Miguel de Icaza <miguel@ximian.com>

536 * rootcontext.cs (RootContext::CreateType): Register all the
537 abstract methods required for the class to be complete and the
538 interface methods that must be implemented.
540 * cs-parser.jay: Report error 501 (method requires body if it is
541 not marked abstract or extern).
543 * expression.cs (TypeOf::Emit): Implement.

547 * class.cs (Property::Emit): Generate code for properties.
549 2001-10-02 Ravi Pratap <ravi@ximian.com>
551 * expression.cs (Unary::ResolveOperator): Find operators on base type
552 too - we now conform exactly to the spec.
554 (Binary::ResolveOperator): Same here.
556 * class.cs (Operator::Define): Fix minor quirk in the tests.
558 * ../errors/cs0215.cs : Added.
560 * ../errors/cs0556.cs : Added.
562 * ../errors/cs0555.cs : Added.
564 2001-10-01 Miguel de Icaza <miguel@ximian.com>
566 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
567 single integer which is really efficient
569 2001-10-01 Ravi Pratap <ravi@ximian.com>
571 * expression.cs (Expression::ImplicitUserConversion): Use location
572 even in the case when we are examining True operators.

575 with the rules for operator overloading in the spec.
577 * expression.cs (Expression::ImplicitReferenceConversion): Implement

583 (cloneable_interface): For System.ICloneable interface.
585 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
586 we start resolving the tree and populating types.
588 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
590 2001-10-01 Miguel de Icaza <miguel@ximian.com>
592 * expression.cs (Expression::ExprClassFromMemberInfo,
593 Expression::Literalize): Create literal expressions from
594 FieldInfos which are literals.
596 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
597 type casts, because they were wrong. The test suite in tests
600 (ImplicitNumericConversion): ushort to ulong requires a widening
603 Int32 constant to long requires widening cast as well.
605 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
606 for integers because the type on the stack is not i4.
608 2001-09-30 Miguel de Icaza <miguel@ximian.com>
610 * expression.cs (report118): require location argument.
612 * parameter.cs: Do not dereference potential null value.
614 * class.cs: Catch methods that lack the `new' keyword when
615 overriding a name. Report warnings when `new' is used without
616 anything being there to override.
618 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
620 * class.cs: Only add constructor to hashtable if it is non-null
621 (as now constructors can fail on define).
623 (TypeManager, Class, Struct): Take location arguments.
625 Catch field instance initialization in structs as errors.
627 accepting_filter: a new filter for FindMembers that is static so
628 that we dont create an instance per invocation.
630 (Constructor::Define): Catch errors where a struct constructor is
633 * cs-parser.jay: Pass location information for various new
636 * delegate.cs (Delegate): take a location argument.
638 * driver.cs: Do not call EmitCode if there were problesm in the
639 Definition of the types, as many Builders wont be there.
641 * decl.cs (Decl::Decl): Require a location argument.
643 * cs-tokenizer.cs: Handle properly hex constants that can not fit
644 into integers, and find the most appropiate integer for it.
646 * literal.cs: Implement ULongLiteral.
648 * rootcontext.cs: Provide better information about the location of
649 failure when CreateType fails.
651 2001-09-29 Miguel de Icaza <miguel@ximian.com>
653 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
656 * expression.cs (Binary::CheckShiftArguments): Add missing type
658 (Binary::ResolveOperator): Add type to the logical and and logical
659 or, Bitwise And/Or and Exclusive Or code paths, it was missing
662 (Binary::DoNumericPromotions): In the case where either argument
663 is ulong (and most signed types combined with ulong cause an
664 error) perform implicit integer constant conversions as well.
666 2001-09-28 Miguel de Icaza <miguel@ximian.com>
668 * expression.cs (UserImplicitCast): Method should always be
670 (Invocation::BetterConversion): Simplified test for IntLiteral.
672 (Expression::ImplicitNumericConversion): Split this routine out.
673 Put the code that performs implicit constant integer conversions
676 (Expression::Resolve): Become a wrapper around DoResolve so we can
677 check eclass and type being set after resolve.
679 (Invocation::Badness): Remove this dead function
681 (Binary::ResolveOperator): Do not compute the expensive argumnets
682 unless we have a union for it.
684 (Probe::Emit): Is needs to do an isinst and then
685 compare against null.
687 (::CanConvert): Added Location argument. If the Location argument
688 is null (Location.Null), then we do not report errors. This is
689 used by the `probe' mechanism of the Explicit conversion. We do
690 not want to generate an error for something that the user
691 explicitly requested to be casted. But the pipeline for an
692 explicit cast first tests for potential implicit casts.
694 So for now, if the Location is null, it means `Probe only' to
695 avoid adding another argument. Might have to revise this
698 (ClassCast): New class used to type cast objects into arbitrary
699 classes (used in Explicit Reference Conversions).
701 Implement `as' as well.
703 Reverted all the patches from Ravi below: they were broken:
705 * The use of `level' as a mechanism to stop recursive
706 invocations is wrong. That was there just to catch the
707 bug with a strack trace but not as a way of addressing
710 To fix the problem we have to *understand* what is going
711 on and the interactions and come up with a plan, not
712 just get things going.
714 * The use of the type conversion cache that I proposed
715 last night had an open topic: How does this work across
716 protection domains. A user defined conversion might not
717 be public in the location where we are applying the
718 conversion, a different conversion might be selected
719 (ie, private A->B (better) but public B->A (worse),
720 inside A, A->B applies, but outside it, B->A will
723 * On top of that (ie, even if the above is solved),
724 conversions in a cache need to be abstract. Ie, `To
725 convert from an Int to a Short use an OpcodeCast', not
726 `To convert from an Int to a Short use the OpcodeCast on
727 the variable 5' (which is what this patch was doing).
729 2001-09-28 Ravi Pratap <ravi@ximian.com>
731 * expression.cs (Invocation::ConversionExists): Re-write to use
734 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
735 cache all conversions done, not just user-defined ones.
737 (Invocation::BetterConversion): The real culprit. Use ConversionExists
738 to determine if a conversion exists instead of acutually trying to
739 perform the conversion. It's faster too.
741 (Expression::ConvertExplicit): Modify to use ConversionExists to check
742 and only then attempt the implicit conversion.
744 2001-09-28 Ravi Pratap <ravi@ximian.com>
746 * expression.cs (ConvertImplicit): Use a cache for conversions
747 already found. Check level of recursion and bail out if necessary.

766 Fix the order in which implicit conversions are
769 The previous fixed dropped support for boxed conversions (adding a
770 test to the test suite now)
772 (UserImplicitCast::CanConvert): Remove test for source being null,
773 that code is broken. We should not feed a null to begin with, if
774 we do, then we should track the bug where the problem originates
775 and not try to cover it up here.
777 Return a resolved expression of type UserImplicitCast on success
778 rather than true/false. Ravi: this is what I was talking about,
779 the pattern is to use a static method as a "constructor" for
782 Also, do not create arguments until the very last minute,
783 otherwise we always create the arguments even for lookups that
784 will never be performed.
786 (UserImplicitCast::Resolve): Eliminate, objects of type
787 UserImplicitCast are born in a fully resolved state.
789 * typemanager.cs (InitCoreTypes): Init also value_type
792 * expression.cs (Cast::Resolve): First resolve the child expression.
794 (LValue): Add new method AddressOf to be used by
797 Change the argument of Store to take an EmitContext instead of an
798 ILGenerator, because things like FieldExpr need to be able to call
799 their children expression to generate the instance code.
801 (Expression::Error, Expression::Warning): Sugar functions for
804 (Expression::MemberLookup): Accept a TypeContainer instead of a
805 Report as the first argument.
807 (Expression::ResolvePrimary): Killed. I still want to improve
808 this as currently the code is just not right.
810 (Expression::ResolveMemberAccess): Simplify, but it is still
813 (Unary::Resolve): Catch errors in AddressOf operators.
815 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
816 index to a byte for the short-version, or the compiler will choose
817 the wrong Emit call, which generates the wrong data.
819 (ParameterReference::Emit, ::Store): same.
821 (FieldExpr::AddressOf): Implement.
823 * typemanager.cs: TypeManager: made public variable instead of
826 * driver.cs: document --fatal.
828 * report.cs (ErrorMessage, WarningMessage): new names for the old
829 Error and Warning classes.
831 * cs-parser.jay (member_access): Turn built-in access to types
832 into a normal simplename
834 2001-09-27 Ravi Pratap <ravi@ximian.com>
836 * expression.cs (Invocation::BetterConversion): Fix to cope
837 with q being null, since this was introducing a bug.
839 * expression.cs (ConvertImplicit): Do built-in conversions first.
841 2001-09-27 Ravi Pratap <ravi@ximian.com>
843 * expression.cs (UserImplicitCast::Resolve): Fix bug.

847 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
848 I had introduced long ago (what's new ?).
850 * expression.cs (UserImplicitCast::CanConvert): Static method to do
851 the work of all the checking.
852 (ConvertImplicit): Call CanConvert and only then create object if necessary.
853 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
855 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
856 that is the right way.
858 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
859 overloading resolution. Use everywhere instead of cutting and pasting code.
861 (Binary::ResolveOperator): Use MakeUnionSet.
863 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
864 we have to convert to bool types. Not complete yet.

868 * typemanager.cs (TypeManager::CSharpName): support ushort.
870 * expression.cs (Expression::TryImplicitIntConversion): Attempts
871 to provide an expression that performsn an implicit constant int
872 conversion (section 6.1.6).
873 (Expression::ConvertImplicitRequired): Reworked to include
874 implicit constant expression conversions.
876 (Expression::ConvertNumericExplicit): Finished.
878 (Invocation::Emit): If InstanceExpression is null, then it means
879 that we perform a call on this.
881 2001-09-26 Miguel de Icaza <miguel@ximian.com>
883 * expression.cs (Unary::Emit): Remove some dead code.
884 (Probe): Implement Resolve and Emit for `is'.
885 (Expression::ConvertImplicitRequired): Attempt to do constant
886 expression conversions here. Maybe should be moved to
887 ConvertImplicit, but I am not sure.
888 (Expression::ImplicitLongConstantConversionPossible,
889 Expression::ImplicitIntConstantConversionPossible): New functions
890 that tell whether is it possible to apply an implicit constant
891 expression conversion.
893 (ConvertNumericExplicit): Started work on explicit numeric
896 * cs-parser.jay: Update operator constants.
898 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs

903 * class.cs (Operator): Update the operator names to reflect the
904 ones that the spec expects (as we are just stringizing the
907 * expression.cs (Unary::ResolveOperator): Fix bug: Use
908 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
909 previous usage did only work for our methods.
910 (Expression::ConvertImplicit): Handle decimal implicit numeric
912 (Expression::InternalTypeConstructor): Used to invoke constructors
913 on internal types for default promotions.
915 (Unary::Emit): Implement special handling for the pre/post
916 increment/decrement for overloaded operators, as they need to have
917 the same semantics as the other operators.
919 (Binary::ResolveOperator): ditto.
920 (Invocation::ConversionExists): ditto.
921 (UserImplicitCast::Resolve): ditto.
923 2001-09-26 Ravi Pratap <ravi@ximian.com>
925 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded

930 (Invocation::OverloadResolve): Ditto.
931 (Invocation::BetterFunction, BetterConversion, ConversionExists): Ditto.

937 * assign.cs (Assign): Make it inherit from ExpressionStatement.
939 * expression.cs (ExpressionStatement): New base class used for
940 expressions that can appear in statements, so that we can provide
941 an alternate path to generate expression that do not leave a value
944 (Expression::Emit, and all the derivatives): We no longer return
945 whether a value is left on the stack or not. Every expression
946 after being emitted leaves a single value on the stack.
948 * codegen.cs (EmitContext::EmitStatementExpression): Use the
949 facilties of ExpressionStatement if possible.
951 * cs-parser.jay: Update statement_expression.

964 * expression.cs (Invocation::ConversionExists): Correct the member lookup
965 to find "op_Implicit", not "implicit" ;-)
966 (UserImplicitCast): New class to take care of user-defined implicit conversions.

976 * assign.cs: track location.
977 (Resolve): Use implicit conversions on assignment.
979 * literal.cs: Oops. Not good, Emit of short access values should

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

1020 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
1021 Also take an additional TypeContainer argument.
1023 * All over : Pass in TypeContainer as argument to OverloadResolve.
1025 * typemanager.cs (CSharpName): Update to check for the string type and return
1028 * expression.cs (Invocation::FullMethodDesc): New static method to return a string fully describing

1042 * typemanager.cs: declare and load enum_type, delegate_type and
1045 * expression.cs (Expression::Emit): Now emit returns a value that
1046 tells whether a value is left on the stack or not. This strategy
1047 might be reveted tomorrow with a mechanism that would address
1048 multiple assignments.
1049 (Expression::report118): Utility routine to report mismatches on
1052 (Unary::Report23): Report impossible type/operator combination
1055 (Unary::IsIncrementableNumber): Whether the type can be

1100 * expression.cs: Instead of having FIXMEs in the Resolve
1101 functions, throw exceptions so it is obvious that we are facing a

1106 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
1107 Use a basename for those routines because .NET does not like paths

1119 * expression.cs (Unary::ResolveOperator): return the child
1120 expression for expressions which are just +expr.
1121 (Unary::ResolveOperator): Return negative literals for -LITERAL
1122 expressions (otherwise they are Unary {Literal}).
1123 (Invocation::Badness): Take into account `Implicit constant
1124 expression conversions'.
1126 * literal.cs (LongLiteral): Implement long literal class.
1127 (IntLiteral): export the `Value' of the intliteral.
1129 2001-09-19 Ravi Pratap <ravi@ximian.com>

1144 * expression.cs (Unary::Resolve): Implement.
1145 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
1146 operators are found instead of making noise ;-)
1147 (Unary::ResolveOperator): New method to do precisely the same thing which
1148 Binary::ResolveOperator does for Binary expressions.
1149 (Unary.method, .Arguments): Add.
1150 (Unary::OperName): Implement.
1151 (Unary::ForceConversion): Copy and Paste !
1153 * class.cs (Operator::Define): Fix a small bug for the case when we have
1156 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
1157 for the inbuilt operators. Only overloading works for now ;-)
1159 2001-09-18 Miguel de Icaza <miguel@ximian.com>
1161 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
1162 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.
1164 * expression.cs (This::Emit): Implement.
1165 (This::Resolve): Implement.

1175 (FieldExpr::Emit): Implement.
1177 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
1178 the last instruction contains a return opcode to avoid generating
1179 the last `ret' instruction (this generates correct code, and it is
1180 nice to pass the peverify output).
1182 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
1183 initializer for static and instance variables.
1184 (Constructor::Emit): Allow initializer to be null in the case of
1185 static constructors. Only emit initializer for instance
1188 (TypeContainer::FindMembers): Return a null array if there are no
1191 Also fix the code for the MemberTypes.Method branch, as it was not
1192 scanning that for operators (or tried to access null variables before).
1194 * assign.cs (Assign::Emit): Handle instance and static fields.
1198 * driver.cs: Stop compilation if there are parse errors.
1200 * cs-parser.jay (constructor_declaration): Provide default base
1201 initializer for non-static constructors.

1203 initializers if none was specified.
1204 Catch the fact that constructors should not have parameters.
1206 * class.cs: Do not emit parent class initializers for static
1207 constructors, that should be flagged as an error.
1209 2001-09-18 Ravi Pratap <ravi@ximian.com>
1211 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
1212 Move back code into TypeContainer::Populate.

1238 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
1241 (Expression::MemberLookup): Provide a version that allows to
1242 specify the MemberTypes and BindingFlags.
1244 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
1245 so it was not fetching variable information from outer blocks.
1247 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
1248 Beforefieldinit as it was buggy.
1250 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
1253 * class.cs (Constructor::Emit): Only emit if block is not null.
1254 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
1255 deal with this by semantically definining it as if the user had
1258 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
1259 constructors as we now "emit" them at a higher level.
1261 (TypeContainer::DefineDefaultConstructor): Used to define the
1262 default constructors if none was provided.
1264 (ConstructorInitializer): Add methods Resolve and Emit.
1266 * expression.cs: Cast to ConstructorInfo instead of MethodInfo
1268 2001-09-17 Ravi Pratap <ravi@ximian.com>

1285 * class.cs (Operator::OpType): Change names to match the ones in Binary::Operator
1286 and Unary::Operator.
1288 * cs-parser.jay (operator_declaration, CheckBinaryOperator, CheckUnaryOperator): Update
1291 * expression.cs (Binary::method): New member to hold the MethodBase for the case when
1292 we have overloaded operators.
1293 (Binary::ResolveOperator): Implement the part which does the operator overload
1296 * class.cs (Operator::Emit): Implement.
1297 (TypeContainer::Emit): Emit the operators we have too.
1299 * expression.cs (Binary::Emit): Update to emit the appropriate code for
1300 the case when we have a user-defined operator.
1302 2001-09-17 Miguel de Icaza <miguel@ximian.com>
1304 * rootcontext.cs: Fix bug: tree.Namespaces might be null.
1306 2001-09-16 Ravi Pratap <ravi@ximian.com>
1308 * class.cs (EmitStaticFieldInitializers, EmitFieldInitializers): Make public.
1309 (TypeContainer::EmitConstructor): Remove and move code into Contructor::Emit.
1310 (Constructor::Emit): Implement.
1311 (EmitStaticFieldInitializers, EmitFieldInitializers): Ensure we return immediately
1312 if we have no work to do.
1313 (TypeContainer::Emit): Pass in TypeContainer as argument to the constructor's

1324 * tree.cs (Tree::namespaces): New hashtable to keep track of namespaces

1332 * rootcontext.cs (IsNamespace): Fixed it :-)
1334 2001-09-14 Miguel de Icaza <miguel@ximian.com>
1336 * class.cs (TypeContainer::FindMembers): Add support for
1338 (MethodCore): New class that encapsulates both the shared aspects
1339 of a Constructor and a Method.
1340 (Method, Constructor): Factored pieces into MethodCore.
1342 * driver.cs: Added --fatal which makes errors throw exceptions.
1343 Load System assembly as well as part of the standard library.
1345 * report.cs: Allow throwing exceptions on errors for debugging.
1347 * modifiers.cs: Do not use `parent', instead use the real type
1348 container to evaluate permission settings.
1350 * class.cs: Put Ravi's patch back in. He is right, and we will
1351 have to cope with the
1353 2001-09-14 Ravi Pratap <ravi@ximian.com>
1355 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
1356 FamORAssem, not FamANDAssem.

1360 * driver.cs: Added --parse option that only parses its input files
1363 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
1364 incorrect. IsTopLevel is not used to tell whether an object is
1365 root_types or not (that can be achieved by testing this ==
1366 root_types). But to see if this is a top-level *class* (not
1367 necessarly our "toplevel" container).
1369 2001-09-14 Ravi Pratap <ravi@ximian.com>
1371 * enum.cs (Enum::Define): Modify to call the Lookup method on the
1372 parent instead of a direct call to GetType.
1374 2001-09-14 Ravi Pratap <ravi@ximian.com>
1376 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
1377 Modifiers.TypeAttr. This should just be a call to that method.
1379 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
1380 object so that we can determine if we are top-level or not.
1382 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
1385 * enum.cs (Enum::Define): Ditto.
1387 * modifiers.cs (FieldAttr): Re-write.
1389 * class.cs (TypeContainer::IsTopLevel): Change accessibility to public.
1390 (TypeContainer::HaveStaticConstructor): New property to provide access
1391 to precisely that info.
1393 * modifiers.cs (MethodAttr): Re-write.
1394 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
1396 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
1397 of top-level types as claimed.
1399 2001-09-13 Miguel de Icaza <miguel@ximian.com>
1401 * expression.cs (MemberLookup): Fruitless attempt to lookup
1402 constructors. Maybe I need to emit default constructors? That
1403 might be it (currently .NET emits this for me automatically).

2017 instead of ignoring the rank_specifiers.
2018 (expression_list): Implement to collect the expressions

2023 (opt_array_initializer): Modify accordingly.
2025 * expression.cs (New::NType): Add enumeration to help us
2026 keep track of whether we have an object/delegate creation
2027 or an array creation.
2028 (New:NewType, New::Rank, New::Indices, New::Initializers): New
2029 members to hold data about array creation.
2030 (New:New): Modify to update NewType
2031 (New:New): New Overloaded contructor for the array creation
2034 * cs-parser.jay (array_creation_expression): Implement to call
2035 the overloaded New constructor.
2037 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
2039 * class.cs (TypeContainer::Constructors): Return member
2040 constructors instead of returning null.
2042 2001-08-26 Miguel de Icaza <miguel@ximian.com>
2044 * typemanager.cs (InitCoreTypes): Initialize the various core
2045 types after we have populated the type manager with the user
2046 defined types (this distinction will be important later while
2047 compiling corlib.dll)
2049 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
2050 on Expression Classification. Now all expressions have a method
2051 `Resolve' and a method `Emit'.
2053 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
2054 generation from working. Also add some temporary debugging
2057 2001-08-24 Miguel de Icaza <miguel@ximian.com>
2059 * codegen.cs: Lots of code generation pieces. This is only the
2060 beginning, will continue tomorrow with more touches of polish. We
2061 handle the fundamentals of if, while, do, for, return. Others are
2062 trickier and I need to start working on invocations soon.
2064 * gen-treedump.cs: Bug fix, use s.Increment here instead of
2067 * codegen.cs (EmitContext): New struct, used during code
2068 emission to keep a context. Most of the code generation will be
2071 * cs-parser.jay: Add embedded blocks to the list of statements of
2072 this block. So code generation proceeds in a top down fashion.
2074 2001-08-23 Miguel de Icaza <miguel@ximian.com>
2076 * statement.cs: Add support for multiple child blocks.
2078 2001-08-22 Miguel de Icaza <miguel@ximian.com>
2080 * codegen.cs (EmitCode): New function, will emit the code for a
2081 Block of code given a TypeContainer and its ILGenerator.
2083 * statement.cs (Block): Standard public readonly optimization.
2084 (Block::Block constructors): Link children.
2085 (Block::Child): Child Linker.
2086 (Block::EmitVariables): Emits IL variable declarations.
2088 * class.cs: Drop support for MethodGroups here, delay until
2090 (Method::): Applied the same simplification that I did before, and
2091 move from Properties to public readonly fields.
2092 (Method::ParameterTypes): Returns the parameter types for the
2093 function, and implements a cache that will be useful later when I
2094 do error checking and the semantic analysis on the methods is
2096 (Constructor::GetCallingConvention): Renamed from CallingConvetion
2097 and made a method, optional argument tells whether this is a class
2098 or a structure to apply the `has-this' bit.
2099 (Method::GetCallingConvention): Implement, returns the calling
2101 (Method::Define): Defines the type, a second pass is performed
2102 later to populate the methods.
2104 (Constructor::ParameterTypes): implement a cache similar to the
2105 one on Method::ParameterTypes, useful later when we do semantic
2108 (TypeContainer::EmitMethod): New method. Emits methods.
2110 * expression.cs: Removed MethodGroup class from here.
2112 * parameter.cs (Parameters::GetCallingConvention): new method.
2114 2001-08-21 Miguel de Icaza <miguel@ximian.com>
2116 * class.cs (TypeContainer::Populate): Drop RootContext from the
2119 (Constructor::CallingConvention): Returns the calling convention.
2120 (Constructor::ParameterTypes): Returns the constructor parameter
2123 (TypeContainer::AddConstructor): Keep track of default constructor
2124 and the default static constructor.
2126 (Constructor::) Another class that starts using `public readonly'
2127 instead of properties.
2129 (Constructor::IsDefault): Whether this is a default constructor.
2131 (Field::) use readonly public fields instead of properties also.
2133 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
2134 track of static constructors; If none is used, turn on
2135 BeforeFieldInit in the TypeAttributes.
2137 * cs-parser.jay (opt_argument_list): now the return can be null
2138 for the cases where there are no arguments.
2140 (constructor_declarator): If there is no implicit `base' or
2141 `this', then invoke the default parent constructor.
2143 * modifiers.cs (MethodAttr): New static function maps a set of
2144 modifiers flags into a MethodAttributes enum
2145 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
2146 MethodAttr, TypeAttr to represent the various mappings where the
2148 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
2150 2001-08-19 Miguel de Icaza <miguel@ximian.com>
2152 * parameter.cs (GetParameterInfo): Fix bug where there would be no
2155 * interface.cs (PopulateIndexer): Implemented the code generator
2156 for interface indexers.
2158 2001-08-17 Miguel de Icaza <miguel@ximian.com>
2160 * interface.cs (InterfaceMemberBase): Now we track the new status
2163 (PopulateProperty): Implement property population. Woohoo! Got
2164 Methods and Properties going today.
2166 Removed all the properties for interfaces, and replaced them with
2167 `public readonly' fields.
2169 2001-08-16 Miguel de Icaza <miguel@ximian.com>
2171 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
2172 initialize their hashtables/arraylists only when they are needed
2173 instead of doing this always.
2175 * parameter.cs: Handle refs and out parameters.
2177 * cs-parser.jay: Use an ArrayList to construct the arguments
2178 instead of the ParameterCollection, and then cast that to a
2181 * parameter.cs: Drop the use of ParameterCollection and use
2182 instead arrays of Parameters.
2184 (GetParameterInfo): Use the Type, not the Name when resolving
2187 2001-08-13 Miguel de Icaza <miguel@ximian.com>
2189 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
2190 and instead use public readonly fields.
2192 * class.cs: Put back walking code for type containers.
2194 2001-08-11 Miguel de Icaza <miguel@ximian.com>
2196 * class.cs (MakeConstant): Code to define constants.
2198 * rootcontext.cs (LookupType): New function. Used to locate types
2201 2001-08-08 Miguel de Icaza <miguel@ximian.com>
2203 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
2204 this System.Reflection code is. Kudos to Microsoft
2206 * typemanager.cs: Implement a type cache and avoid loading all
2207 types at boot time. Wrap in LookupType the internals. This made
2208 the compiler so much faster. Wow. I rule!
2210 * driver.cs: Make sure we always load mscorlib first (for
2211 debugging purposes, nothing really important).
2213 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
2214 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
2216 * rootcontext.cs: Lookup types on their namespace; Lookup types
2217 on namespaces that have been imported using the `using' keyword.
2219 * class.cs (TypeContainer::TypeAttr): Virtualize.
2220 (Class::TypeAttr): Return attributes suitable for this bad boy.
2221 (Struct::TypeAttr): ditto.
2222 Handle nested classes.
2223 (TypeContainer::) Remove all the type visiting code, it is now
2224 replaced with the rootcontext.cs code
2226 * rootcontext.cs (GetClassBases): Added support for structs.
2228 2001-08-06 Miguel de Icaza <miguel@ximian.com>
2230 * interface.cs, statement.cs, class.cs, parameter.cs,
2231 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
2232 Drop use of TypeRefs, and use strings instead.
2234 2001-08-04 Miguel de Icaza <miguel@ximian.com>
2238 * class.cs (Struct::Struct): set the SEALED flags after
2239 checking the modifiers.
2240 (TypeContainer::TypeAttr): new property, returns the
2241 TypeAttributes for a class.
2243 * cs-parser.jay (type_list): Oops, list production was creating a
2244 new list of base types.
2246 * rootcontext.cs (StdLib): New property.
2247 (GetInterfaceTypeByName): returns an interface by type name, and
2248 encapsulates error handling here.
2249 (GetInterfaces): simplified.
2250 (ResolveTree): Encapsulated all the tree resolution here.
2251 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
2254 * driver.cs: Add support for --nostdlib, to avoid loading the
2256 (Main): Do not put tree resolution here.
2258 * rootcontext.cs: Beginning of the class resolution.
2260 2001-08-03 Miguel de Icaza <miguel@ximian.com>
2262 * rootcontext.cs: Provide better error reporting.
2264 * cs-parser.jay (interface_base): set our $$ to be interfaces.
2266 * rootcontext.cs (CreateInterface): Handle the case where there
2267 are no parent interfaces.
2269 (CloseTypes): Routine to flush types at the end.
2270 (CreateInterface): Track types.
2271 (GetInterfaces): Returns an array of Types from the list of
2274 * typemanager.c (AddUserType): Mechanism to track user types (puts
2275 the type on the global type hash, and allows us to close it at the
2278 2001-08-02 Miguel de Icaza <miguel@ximian.com>
2280 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
2281 RecordInterface instead.
2283 * cs-parser.jay: Updated to reflect changes above.
2285 * decl.cs (Definition): Keep track of the TypeBuilder type that
2286 represents this type here. Not sure we will use it in the long
2287 run, but wont hurt for now.
2289 * driver.cs: Smaller changes to accomodate the new code.
2291 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
2294 * rootcontext.cs (CreateInterface): New method, used to create
2295 the System.TypeBuilder type for interfaces.
2296 (ResolveInterfaces): new entry point to resolve the interface
2298 (CodeGen): Property, used to keep track of the code generator.
2300 2001-07-26 Miguel de Icaza <miguel@ximian.com>
2302 * cs-parser.jay: Add a second production for delegate_declaration
2305 (enum_body): Put an opt_comma here instead of putting it on
2306 enum_body or enum_member_declarations so we can handle trailing
2307 commas on enumeration members. Gets rid of a shift/reduce.
2309 (type_list): Need a COMMA in the middle.
2311 (indexer_declaration): Tell tokenizer to recognize get/set
2313 * Remove old targets.
2315 * Re-add the parser target.
2317 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2319 * cs-parser.jay: Add precendence rules for a number of operators
2320 ot reduce the number of shift/reduce conflicts in the grammar.
2322 2001-07-17 Miguel de Icaza <miguel@ximian.com>
2324 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
2327 Get rid of old crufty code.
2329 * rootcontext.cs: Use this to keep track of the parsed
2330 representation and the defined types available to the program.
2332 * gen-treedump.cs: adjust for new convention.
2334 * type.cs: Split out the type manager, and the assembly builder
2337 * typemanager.cs: the type manager will live here now.
2339 * cil-codegen.cs: And the code generator here.
2341 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
2343 * makefile: Fixed up for easy making.
2345 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2347 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
2350 (unary_expression): Expand pre_increment_expression and
2351 post_decrement_expression to reduce a shift/reduce.
2353 2001-07-11 Simon Cozens
2355 * cs-tokenizer.cs: Hex numbers should begin with a 0.
2357 Improve allow_keyword_as_indent name.
2359 2001-06-19 Miguel de Icaza <miguel@ximian.com>
2361 * Adjustments for Beta2.
2363 2001-06-13 Miguel de Icaza <miguel@ximian.com>
2365 * decl.cs: Added `Define' abstract method.
2366 (InTransit): new property, used to catch recursive definitions.
2368 * interface.cs: Implement `Define'.
2370 * modifiers.cs: Map Modifiers.constants to
2371 System.Reflection.TypeAttribute flags.
2373 * class.cs: Keep track of types and user-defined types.
2374 (BuilderInit): New method for creating an assembly
2375 (ResolveType): New function to launch the resolution process, only
2376 used by interfaces for now.
2378 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
2379 that are inserted into the name space.
2381 2001-06-08 Miguel de Icaza <miguel@ximian.com>
2383 * ARGH. I have screwed up my tree so many times due to the use of
2384 rsync rather than using CVS. Going to fix this at once.
2386 * driver.cs: Objetify driver. Load assemblies, use assemblies to
2389 2001-06-07 Miguel de Icaza <miguel@ximian.com>
2391 * Experiment successful: Use System.Type rather that our own
2394 2001-05-25 Miguel de Icaza <miguel@ximian.com>
2396 * cs-parser.jay: Removed nsAliases from here.
2398 Use new namespaces, handle `using XXX;'
2400 * namespace.cs: Reimplemented namespace handling, use a recursive
2401 definition of the class. Now we can keep track of using clauses
2402 and catch invalid using clauses.
2404 2001-05-24 Miguel de Icaza <miguel@ximian.com>
2406 * gen-treedump.cs: Adapted for all the renaming.
2408 * expression.cs (Expression): this class now has a Type property
2409 which returns an expression Type.
2411 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
2412 `Type', as this has a different meaning now in the base
2414 2001-05-22 Miguel de Icaza <miguel@ximian.com>
2416 * interface.cs, class.cs: Removed from all the sources the
2417 references to signature computation, as we can not do method
2418 signature computation during the parsing time, as we are not
2419 trying to solve at that point distinguishing:
2423 void a (NS.Blah x) {}
2426 Which depending on the context might be valid or not, as we do not
2427 know if Blah is the same thing as NS.Blah at that point.
2429 * Redid everything so the code uses TypeRefs now instead of
2430 Types. TypeRefs are just temporary type placeholders, that need
2431 to be resolved. They initially have a pointer to a string and the
2432 current scope in which they are used. This is used later by the
2433 compiler to resolve the reference to an actual Type.
2435 * DeclSpace is no longer a CIR.Type, and neither are
2436 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
2437 are all DeclSpaces, but no Types.
2439 * type.cs (TypeRefManager): This implements the TypeRef manager,
2440 which keeps track of all the types that need to be resolved after
2441 the parsing has finished.
2443 2001-05-13 Miguel de Icaza <miguel@ximian.com>
2445 * ARGH. We are going to have to store `foreach' as a class rather
2446 than resolving it, as we need to verify error 1579 after name
2447 resolution. *OR* we could keep a flag that says `This request to
2448 IEnumerator comes from a foreach statement' which we can then use
2449 to generate the error.
2451 2001-05-10 Miguel de Icaza <miguel@ximian.com>
2453 * class.cs (TypeContainer.AddMethod): we now add methods to the
2454 MethodGroup instead of the method hashtable.
2456 * expression.cs: Add MethodGroup abstraction, which gets us one
2457 step closer to the specification in the way we handle method
2460 * cs-parser.jay (primary_expression): qualified_identifier now
2461 tried to match up an identifier to a local variable reference or
2462 to a parameter reference.
2464 current_local_parameters is now a parser global variable that
2465 points to the current parameters for the block, used during name
2468 (property_declaration): Now creates an implicit `value' argument to
2471 2001-05-09 Miguel de Icaza <miguel@ximian.com>
2473 * parameter.cs: Do not use `param' arguments as part of the
2474 signature, per the spec.
2476 2001-05-08 Miguel de Icaza <miguel@ximian.com>
2478 * decl.cs: Base class for classes, structs and interfaces. This
2479 is the "Declaration Space"
2481 * cs-parser.jay: Use CheckDef for checking declaration errors
2482 instead of having one on each function.
2484 * class.cs: Factor out some code for handling error handling in
2485 accordance to the "Declarations" section in the "Basic Concepts"
2486 chapter in the ECMA C# spec.
2488 * interface.cs: Make all interface member classes derive from
2489 InterfaceMemberBase.
2491 2001-05-07 Miguel de Icaza <miguel@ximian.com>
2493 * Many things: all interfaces are parsed and generated in
2494 gen-treedump. Support for member variables, constructors,
2495 destructors, properties, constants is there.
2497 Beginning of the IL backend, but very little done, just there for
2500 2001-04-29 Miguel de Icaza <miguel@ximian.com>
2502 * cs-parser.jay: Fix labeled statement.
2504 * cs-tokenizer.cs (escape): Escape " and ' always.
2505 ref_line, ref_name: keep track of the line/filename as instructed
2506 by #line by the compiler.
2509 2001-04-27 Miguel de Icaza <miguel@ximian.com>
2511 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
2512 to match the values in System.CodeDOM.
2514 Divid renamed to Divide.
2516 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
2518 (Statements.set): remove.
2520 * System.CodeDOM/CodeCatchClause.cs: always have a valid
2523 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
2524 falseStatements always have valid values.
2526 * cs-parser.jay: Use System.CodeDOM now.
