11 * expression.cs (ElementAccess::DoResolve): Remove my crap code
12 and start performing checks according to the spec.
14 2001-10-07 Ravi Pratap <ravi@ximian.com>
16 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
17 rank_specifiers instead.
19 (rank_specifiers): Change the order in which the rank specifiers are stored
21 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
23 * expression.cs (ElementAccess): Implement the LValue interface too.

30 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
31 perform the conversion of the return type, if necessary.

46 * cs-parser.jay: Added support for try/catch/finalize.
48 * class.cs: Catch static methods having the flags override,
51 * expression.cs (UserCast): This user cast was not really doing
52 what it was supposed to do. Which is to be born in fully resolved
53 state. Parts of the resolution were being performed at Emit time!
57 2001-10-05 Miguel de Icaza <miguel@ximian.com>
59 * expression.cs: Implicity convert the result from UserCast.
61 2001-10-05 Ravi Pratap <ravi@ximian.com>
63 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
64 prevented it from working correctly.

71 * typemanager.cs: Make the LookupTypeContainer function static,
74 * class.cs: Make static FindMembers (the one that takes a Type
77 * codegen.cs: Add EmitForeach here.
79 * cs-parser.jay: Make foreach a toplevel object instead of the
80 inline expansion, as we need to perform semantic analysis on it.

84 * expression.cs (Expression::ImplicitUserConversion): Rename to
85 UserDefinedConversion.
87 (Expression::UserDefinedConversion): Take an extra argument specifying
88 whether we look for explicit user conversions too.
90 (Expression::ImplicitUserConversion): Make it a call to UserDefinedConversion.
92 (UserDefinedConversion): Incorporate support for user defined explicit conversions.
94 (ExplicitUserConversion): Make it a call to UserDefinedConversion
95 with the appropriate arguments.
97 * cs-parser.jay (cast_expression): Record location too.
99 * expression.cs (Cast): Record location info.
101 (Expression::ConvertExplicit): Take location argument.
103 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
104 to determine if we are doing explicit conversions.
106 (UserCast::Emit): Update accordingly.
108 (Expression::ConvertExplicit): Report an error if everything fails.
110 * ../errors/cs0030.cs : Add.
112 2001-10-04 Miguel de Icaza <miguel@ximian.com>
114 * modifiers.cs: If the ABSTRACT keyword is present, also set the
115 virtual and newslot bits.
117 * class.cs (TypeContainer::RegisterRequiredImplementations):
118 Record methods we need.
120 (TypeContainer::MakeKey): Helper function to make keys for
121 MethodBases, since the Methodbase key is useless.
123 (TypeContainer::Populate): Call RegisterRequiredImplementations
124 before defining the methods.
126 Create a mapping for method_builders_to_methods ahead of time
127 instead of inside a tight loop.
129 (::RequireMethods): Accept an object as the data to set into the
130 hashtable so we can report interface vs abstract method mismatch.
132 2001-10-03 Miguel de Icaza <miguel@ximian.com>
134 * report.cs: Make all of it static.
136 * rootcontext.cs: Drop object_type and value_type computations, as
137 we have those in the TypeManager anyways.
139 Drop report instance variable too, now it is a global.
141 * driver.cs: Use try/catch on command line handling.
143 Add --probe option to debug the error reporting system with a test
146 * report.cs: Add support for exiting program when a probe
147 condition is reached.
149 2001-10-03 Ravi Pratap <ravi@ximian.com>
151 * expression.cs (Binary::DoNumericPromotions): Fix the case when
152 we do a forcible conversion regardless of type, to check if
153 ForceConversion returns a null.
155 (Binary::error19): Use location to report error.
157 (Unary::error23): Use location here too.
159 * ../errors/cs0019.cs : Check in.
161 * ../errors/cs0023.cs : Check in.
163 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
164 case of a non-null MethodInfo object with a length of 0 !
166 (Binary::ResolveOperator): Flag error if overload resolution fails to find
167 an applicable member - according to the spec :-)
168 Also fix logic to find members in base types.
170 (Unary::ResolveOperator): Same here.
172 (Unary::report23): Change name to error23 and make first argument a TypeContainer
173 as I was getting thoroughly confused between this and error19 :-)
175 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
176 (::FindMostEncompassedType): Implement.
177 (::FindMostEncompassingType): Implement.
178 (::StandardConversionExists): Implement.
180 (UserImplicitCast): Re-vamp. We now need info about most specific
181 source and target types so that we can do the necessary conversions.
183 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
184 mathematical union with no duplicates.
186 2001-10-03 Miguel de Icaza <miguel@ximian.com>
188 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
189 in order from base classes to child classes, so that we can in
190 child classes look up in our parent for method names and
191 attributes (required for handling abstract, virtual, new, override
192 constructs: we need to instrospect our base class, and if we dont
193 populate the classes in order, the introspection might be
194 incorrect. For example, a method could query its parent before
195 the parent has any methods and would determine that the parent has
196 no abstract methods (while it could have had them)).
198 (RootContext::CreateType): Record the order in which we define the
201 2001-10-02 Miguel de Icaza <miguel@ximian.com>
203 * class.cs (TypeContainer::Populate): Also method definitions can
204 fail now, keep track of this.

214 * rootcontext.cs (RootContext::CreateType): Register all the
215 abstract methods required for the class to be complete and the
216 interface methods that must be implemented.
218 * cs-parser.jay: Report error 501 (method requires body if it is
219 not marked abstract or extern).
221 * expression.cs (TypeOf::Emit): Implement.
223 * typemanager.cs: runtime_handle_type, new global type.
225 * class.cs (Property::Emit): Generate code for properties.
227 2001-10-02 Ravi Pratap <ravi@ximian.com>
229 * expression.cs (Unary::ResolveOperator): Find operators on base type
230 too - we now conform exactly to the spec.
232 (Binary::ResolveOperator): Same here.
234 * class.cs (Operator::Define): Fix minor quirk in the tests.
236 * ../errors/cs0215.cs : Added.
238 * ../errors/cs0556.cs : Added.
240 * ../errors/cs0555.cs : Added.
242 2001-10-01 Miguel de Icaza <miguel@ximian.com>
244 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
245 single integer which is really efficient
247 2001-10-01 Ravi Pratap <ravi@ximian.com>
249 * expression.cs (Expression::ImplicitUserConversion): Use location
250 even in the case when we are examining True operators.
252 * class.cs (Operator::Define): Perform extensive checks to conform
253 with the rules for operator overloading in the spec.
255 * expression.cs (Expression::ImplicitReferenceConversion): Implement
256 some of the other conversions mentioned in the spec.

266 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
268 2001-10-01 Miguel de Icaza <miguel@ximian.com>
270 * expression.cs (Expression::ExprClassFromMemberInfo,
271 Expression::Literalize): Create literal expressions from
272 FieldInfos which are literals.
274 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
275 type casts, because they were wrong. The test suite in tests
278 (ImplicitNumericConversion): ushort to ulong requires a widening
281 Int32 constant to long requires widening cast as well.
283 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
284 for integers because the type on the stack is not i4.
286 2001-09-30 Miguel de Icaza <miguel@ximian.com>
288 * expression.cs (report118): require location argument.
290 * parameter.cs: Do not dereference potential null value.
292 * class.cs: Catch methods that lack the `new' keyword when
293 overriding a name. Report warnings when `new' is used without
294 anything being there to override.
296 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
298 * class.cs: Only add constructor to hashtable if it is non-null
299 (as now constructors can fail on define).
301 (TypeManager, Class, Struct): Take location arguments.
303 Catch field instance initialization in structs as errors.
305 accepting_filter: a new filter for FindMembers that is static so
306 that we dont create an instance per invocation.
308 (Constructor::Define): Catch errors where a struct constructor is
311 * cs-parser.jay: Pass location information for various new
314 * delegate.cs (Delegate): take a location argument.
316 * driver.cs: Do not call EmitCode if there were problesm in the
317 Definition of the types, as many Builders wont be there.
319 * decl.cs (Decl::Decl): Require a location argument.
321 * cs-tokenizer.cs: Handle properly hex constants that can not fit
322 into integers, and find the most appropiate integer for it.
324 * literal.cs: Implement ULongLiteral.
326 * rootcontext.cs: Provide better information about the location of
327 failure when CreateType fails.
329 2001-09-29 Miguel de Icaza <miguel@ximian.com>
331 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
334 * expression.cs (Binary::CheckShiftArguments): Add missing type
336 (Binary::ResolveOperator): Add type to the logical and and logical
337 or, Bitwise And/Or and Exclusive Or code paths, it was missing
340 (Binary::DoNumericPromotions): In the case where either argument
341 is ulong (and most signed types combined with ulong cause an
342 error) perform implicit integer constant conversions as well.
344 2001-09-28 Miguel de Icaza <miguel@ximian.com>
346 * expression.cs (UserImplicitCast): Method should always be
348 (Invocation::BetterConversion): Simplified test for IntLiteral.
350 (Expression::ImplicitNumericConversion): Split this routine out.
351 Put the code that performs implicit constant integer conversions
354 (Expression::Resolve): Become a wrapper around DoResolve so we can
355 check eclass and type being set after resolve.
357 (Invocation::Badness): Remove this dead function
359 (Binary::ResolveOperator): Do not compute the expensive argumnets
360 unless we have a union for it.
362 (Probe::Emit): Is needs to do an isinst and then
363 compare against null.
365 (::CanConvert): Added Location argument. If the Location argument
366 is null (Location.Null), then we do not report errors. This is
367 used by the `probe' mechanism of the Explicit conversion. We do
368 not want to generate an error for something that the user
369 explicitly requested to be casted. But the pipeline for an
370 explicit cast first tests for potential implicit casts.
372 So for now, if the Location is null, it means `Probe only' to
373 avoid adding another argument. Might have to revise this
376 (ClassCast): New class used to type cast objects into arbitrary
377 classes (used in Explicit Reference Conversions).
379 Implement `as' as well.
381 Reverted all the patches from Ravi below: they were broken:
383 * The use of `level' as a mechanism to stop recursive
384 invocations is wrong. That was there just to catch the
385 bug with a strack trace but not as a way of addressing
388 To fix the problem we have to *understand* what is going
389 on and the interactions and come up with a plan, not
390 just get things going.
392 * The use of the type conversion cache that I proposed
393 last night had an open topic: How does this work across
394 protection domains. A user defined conversion might not
395 be public in the location where we are applying the
396 conversion, a different conversion might be selected
397 (ie, private A->B (better) but public B->A (worse),
398 inside A, A->B applies, but outside it, B->A will
401 * On top of that (ie, even if the above is solved),
402 conversions in a cache need to be abstract. Ie, `To
403 convert from an Int to a Short use an OpcodeCast', not
404 `To convert from an Int to a Short use the OpcodeCast on
405 the variable 5' (which is what this patch was doing).
407 2001-09-28 Ravi Pratap <ravi@ximian.com>
409 * expression.cs (Invocation::ConversionExists): Re-write to use
412 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
413 cache all conversions done, not just user-defined ones.
415 (Invocation::BetterConversion): The real culprit. Use ConversionExists
416 to determine if a conversion exists instead of acutually trying to
417 perform the conversion. It's faster too.
419 (Expression::ConvertExplicit): Modify to use ConversionExists to check
420 and only then attempt the implicit conversion.
422 2001-09-28 Ravi Pratap <ravi@ximian.com>
424 * expression.cs (ConvertImplicit): Use a cache for conversions
425 already found. Check level of recursion and bail out if necessary.
427 2001-09-28 Miguel de Icaza <miguel@ximian.com>
429 * typemanager.cs (string_concat_string_string, string_concat_object_object):
430 Export standard methods that we expect for string operations.
432 * statement.cs (Block::UsageWarning): Track usage of variables and
433 report the errors for not used variables.
435 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
438 2001-09-27 Miguel de Icaza <miguel@ximian.com>
440 * codegen.cs: remove unnneded code
442 * expression.cs: Removed BuiltinTypeAccess class
444 Fix the order in which implicit conversions are
447 The previous fixed dropped support for boxed conversions (adding a
448 test to the test suite now)
450 (UserImplicitCast::CanConvert): Remove test for source being null,
451 that code is broken. We should not feed a null to begin with, if
452 we do, then we should track the bug where the problem originates
453 and not try to cover it up here.
455 Return a resolved expression of type UserImplicitCast on success
456 rather than true/false. Ravi: this is what I was talking about,
457 the pattern is to use a static method as a "constructor" for
460 Also, do not create arguments until the very last minute,
461 otherwise we always create the arguments even for lookups that
462 will never be performed.
464 (UserImplicitCast::Resolve): Eliminate, objects of type
465 UserImplicitCast are born in a fully resolved state.
467 * typemanager.cs (InitCoreTypes): Init also value_type
470 * expression.cs (Cast::Resolve): First resolve the child expression.
472 (LValue): Add new method AddressOf to be used by
475 Change the argument of Store to take an EmitContext instead of an
476 ILGenerator, because things like FieldExpr need to be able to call
477 their children expression to generate the instance code.
479 (Expression::Error, Expression::Warning): Sugar functions for
482 (Expression::MemberLookup): Accept a TypeContainer instead of a
483 Report as the first argument.
485 (Expression::ResolvePrimary): Killed. I still want to improve
486 this as currently the code is just not right.
488 (Expression::ResolveMemberAccess): Simplify, but it is still
491 (Unary::Resolve): Catch errors in AddressOf operators.
493 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
494 index to a byte for the short-version, or the compiler will choose
495 the wrong Emit call, which generates the wrong data.
497 (ParameterReference::Emit, ::Store): same.
499 (FieldExpr::AddressOf): Implement.
501 * typemanager.cs: TypeManager: made public variable instead of
504 * driver.cs: document --fatal.
506 * report.cs (ErrorMessage, WarningMessage): new names for the old
507 Error and Warning classes.
509 * cs-parser.jay (member_access): Turn built-in access to types
510 into a normal simplename
512 2001-09-27 Ravi Pratap <ravi@ximian.com>
514 * expression.cs (Invocation::BetterConversion): Fix to cope
515 with q being null, since this was introducing a bug.

526 I had introduced long ago (what's new ?).
528 * expression.cs (UserImplicitCast::CanConvert): Static method to do
529 the work of all the checking.
530 (ConvertImplicit): Call CanConvert and only then create object if necessary.
531 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
533 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
534 that is the right way.
536 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
537 overloading resolution. Use everywhere instead of cutting and pasting code.
539 (Binary::ResolveOperator): Use MakeUnionSet.
541 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
542 we have to convert to bool types. Not complete yet.
544 2001-09-27 Miguel de Icaza <miguel@ximian.com>
546 * typemanager.cs (TypeManager::CSharpName): support ushort.
548 * expression.cs (Expression::TryImplicitIntConversion): Attempts
549 to provide an expression that performsn an implicit constant int
550 conversion (section 6.1.6).
551 (Expression::ConvertImplicitRequired): Reworked to include
552 implicit constant expression conversions.
554 (Expression::ConvertNumericExplicit): Finished.
556 (Invocation::Emit): If InstanceExpression is null, then it means
557 that we perform a call on this.
559 2001-09-26 Miguel de Icaza <miguel@ximian.com>
561 * expression.cs (Unary::Emit): Remove some dead code.
562 (Probe): Implement Resolve and Emit for `is'.
563 (Expression::ConvertImplicitRequired): Attempt to do constant
564 expression conversions here. Maybe should be moved to
565 ConvertImplicit, but I am not sure.
566 (Expression::ImplicitLongConstantConversionPossible,
567 Expression::ImplicitIntConstantConversionPossible): New functions
568 that tell whether is it possible to apply an implicit constant
569 expression conversion.
571 (ConvertNumericExplicit): Started work on explicit numeric
574 * cs-parser.jay: Update operator constants.
576 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
577 (Parameters::GetSignature): Hook up VerifyArgs here.
578 (Parameters::VerifyArgs): Verifies that no two arguments have the
581 * class.cs (Operator): Update the operator names to reflect the
582 ones that the spec expects (as we are just stringizing the
585 * expression.cs (Unary::ResolveOperator): Fix bug: Use
586 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
587 previous usage did only work for our methods.
588 (Expression::ConvertImplicit): Handle decimal implicit numeric
590 (Expression::InternalTypeConstructor): Used to invoke constructors
591 on internal types for default promotions.
593 (Unary::Emit): Implement special handling for the pre/post
594 increment/decrement for overloaded operators, as they need to have
595 the same semantics as the other operators.
597 (Binary::ResolveOperator): ditto.
598 (Invocation::ConversionExists): ditto.
599 (UserImplicitCast::Resolve): ditto.
601 2001-09-26 Ravi Pratap <ravi@ximian.com>

613 2001-09-26 Miguel de Icaza <miguel@ximian.com>
615 * assign.cs (Assign): Make it inherit from ExpressionStatement.
617 * expression.cs (ExpressionStatement): New base class used for
618 expressions that can appear in statements, so that we can provide
619 an alternate path to generate expression that do not leave a value
622 (Expression::Emit, and all the derivatives): We no longer return
623 whether a value is left on the stack or not. Every expression
624 after being emitted leaves a single value on the stack.
626 * codegen.cs (EmitContext::EmitStatementExpression): Use the
627 facilties of ExpressionStatement if possible.
629 * cs-parser.jay: Update statement_expression.

639 we have an overloaded operator match ! The regression tests pass again !
640 (Unary::ResolveOperator): Ditto.
642 * expression.cs (Invocation::ConversionExists): Correct the member lookup
643 to find "op_Implicit", not "implicit" ;-)
644 (UserImplicitCast): New class to take care of user-defined implicit conversions.

654 * assign.cs: track location.
655 (Resolve): Use implicit conversions on assignment.
657 * literal.cs: Oops. Not good, Emit of short access values should
658 pass (Bytes) or the wrong argument will be selected.
660 * expression.cs (Unary::Emit): Emit code for -expr.
662 (Unary::ResolveOperator): Handle `Substract' for non-constants
663 (substract from zero from the non-constants).
664 Deal with Doubles as well.
666 (Expression::ConvertImplicitRequired): New routine that reports an
667 error if no implicit conversion exists.
669 (Invocation::OverloadResolve): Store the converted implicit
670 expressions if we make them

699 Also take an additional TypeContainer argument.
701 * All over : Pass in TypeContainer as argument to OverloadResolve.
703 * typemanager.cs (CSharpName): Update to check for the string type and return
706 * expression.cs (Invocation::FullMethodDesc): New static method to return a string fully describing

720 * typemanager.cs: declare and load enum_type, delegate_type and
723 * expression.cs (Expression::Emit): Now emit returns a value that
724 tells whether a value is left on the stack or not. This strategy

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

791 2001-09-19 Miguel de Icaza <miguel@ximian.com>
793 * typemanager.cs (TypeManager::CoreLookupType): A function to make sure that we

797 * expression.cs (Unary::ResolveOperator): return the child
798 expression for expressions which are just +expr.
799 (Unary::ResolveOperator): Return negative literals for -LITERAL
800 expressions (otherwise they are Unary {Literal}).

802 expression conversions'.
804 * literal.cs (LongLiteral): Implement long literal class.
805 (IntLiteral): export the `Value' of the intliteral.
807 2001-09-19 Ravi Pratap <ravi@ximian.com>
809 * expression.cs (Binary::Emit): Finally get the emission right ! Woo!

825 (Unary::ResolveOperator): New method to do precisely the same thing which
826 Binary::ResolveOperator does for Binary expressions.
827 (Unary.method, .Arguments): Add.
828 (Unary::OperName): Implement.
829 (Unary::ForceConversion): Copy and Paste !
831 * class.cs (Operator::Define): Fix a small bug for the case when we have
834 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
835 for the inbuilt operators. Only overloading works for now ;-)
837 2001-09-18 Miguel de Icaza <miguel@ximian.com>

853 (FieldExpr::Emit): Implement.
855 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
856 the last instruction contains a return opcode to avoid generating
857 the last `ret' instruction (this generates correct code, and it is
858 nice to pass the peverify output).
860 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
861 initializer for static and instance variables.
862 (Constructor::Emit): Allow initializer to be null in the case of
863 static constructors. Only emit initializer for instance
866 (TypeContainer::FindMembers): Return a null array if there are no
869 Also fix the code for the MemberTypes.Method branch, as it was not
870 scanning that for operators (or tried to access null variables before).
872 * assign.cs (Assign::Emit): Handle instance and static fields.
876 * driver.cs: Stop compilation if there are parse errors.
878 * cs-parser.jay (constructor_declaration): Provide default base
879 initializer for non-static constructors.

881 initializers if none was specified.
882 Catch the fact that constructors should not have parameters.
884 * class.cs: Do not emit parent class initializers for static
885 constructors, that should be flagged as an error.
887 2001-09-18 Ravi Pratap <ravi@ximian.com>

916 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
919 (Expression::MemberLookup): Provide a version that allows to
920 specify the MemberTypes and BindingFlags.
922 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
923 so it was not fetching variable information from outer blocks.

926 Beforefieldinit as it was buggy.
928 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200

932 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
933 deal with this by semantically definining it as if the user had
936 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
937 constructors as we now "emit" them at a higher level.
939 (TypeContainer::DefineDefaultConstructor): Used to define the

1025 * modifiers.cs: Do not use `parent', instead use the real type
1026 container to evaluate permission settings.

1029 have to cope with the
1031 2001-09-14 Ravi Pratap <ravi@ximian.com>
1033 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
1034 FamORAssem, not FamANDAssem.

1038 * driver.cs: Added --parse option that only parses its input files
1041 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
1042 incorrect. IsTopLevel is not used to tell whether an object is
1043 root_types or not (that can be achieved by testing this ==
1044 root_types). But to see if this is a top-level *class* (not
1045 necessarly our "toplevel" container).
1047 2001-09-14 Ravi Pratap <ravi@ximian.com>
1049 * enum.cs (Enum::Define): Modify to call the Lookup method on the

1054 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
1055 Modifiers.TypeAttr. This should just be a call to that method.
1057 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
1058 object so that we can determine if we are top-level or not.
1060 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
1063 * enum.cs (Enum::Define): Ditto.
1065 * modifiers.cs (FieldAttr): Re-write.
1067 * class.cs (TypeContainer::IsTopLevel): Change accessibility to public.
1068 (TypeContainer::HaveStaticConstructor): New property to provide access
1069 to precisely that info.
1071 * modifiers.cs (MethodAttr): Re-write.
1072 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
1074 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
1075 of top-level types as claimed.
1077 2001-09-13 Miguel de Icaza <miguel@ximian.com>
1079 * expression.cs (MemberLookup): Fruitless attempt to lookup
1080 constructors. Maybe I need to emit default constructors? That
1081 might be it (currently .NET emits this for me automatically).
1082 (Invocation::OverloadResolve): Cope with Arguments == null.
1083 (Invocation::EmitArguments): new function, shared by the new
1085 (Invocation::Emit): Handle static and instance methods. Emit

1097 SimpleLookup): Auxiliary routines to help parse a qualifier
1100 Update qualifier_identifier rule.
1102 * codegen.cs: Removed debugging messages.

1105 objects that we might have around.
1107 (Populate): Only initialize method_builders_to_methods once.
1109 * expression.cs (PropertyExpr): Initialize type from the
1112 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
1113 Resolve pattern. Attempt to implicitly convert value to boolean.
1116 * expression.cs: Set the type for the int32/int32 argument case.
1117 (Binary::ResolveOperator): Set the return type to boolean for
1118 comparission operators
1120 * typemanager.cs: Remove debugging print code.
1122 (Invocation::Resolve): resolve type.
1124 * class.cs: Allocate a MemberInfo of the correct size, as the code
1125 elsewhere depends on the test to reflect the correct contents.
1127 (Method::) Keep track of parameters, due to System.Reflection holes
1129 (TypeContainer::Populate): Keep track of MethodBuilders to Method
1132 (TypeContainer::FindMembers): Use ArrayList and then copy an array
1133 of the exact size and return that.
1135 (Class::LookupMethodByBuilder): New function that maps
1136 MethodBuilders to its methods. Required to locate the information
1137 on methods because System.Reflection bit us again.
1139 * support.cs: New file, contains an interface ParameterData and
1140 two implementations: ReflectionParameters and InternalParameters
1141 used to access Parameter information. We will need to grow this
1144 * expression.cs (Invocation::GetParameterData): implement a cache
1145 and a wrapper around the ParameterData creation for methods.
1146 (Invocation::OverloadResolve): Use new code.
1148 2001-09-13 Ravi Pratap <ravi@ximian.com>
1150 * class.cs (TypeContainer::EmitField): Remove and move into
1151 (Field::Define): here and modify accordingly.
1152 (Field.FieldBuilder): New member.
1153 (TypeContainer::Populate): Update accordingly.
1154 (TypeContainer::FindMembers): Implement.
1156 2001-09-13 Miguel de Icaza <miguel@ximian.com>
1158 * statement.cs: (VariableInfo::VariableType): New field to be
1159 initialized with the full type once it is resolved.
1161 2001-09-12 Miguel de Icaza <miguel@ximian.com>

1170 (ParameterReference::Emit): Implement.
1172 * cs-parser.jay: Fix bug introduced by Ravi, variable initializers

1202 2001-09-12 Ravi Pratap <ravi@ximian.com>
1204 * class.cs (TypeContainer::FindMembers): Method which does exactly
1205 what Type.FindMembers does, only we don't have to use reflection. No
1208 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
1209 typecontainer objects as we need to get at them.
1210 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.
1212 * rootcontext.cs : Correspondingly modify called to AddUserType to pass the
1213 typecontainer object.

1237 (Event::Define): Ditto.
1238 (Property::Define): Ditto.

1251 * class.cs (Event::Define): Make the prefixes of the accessor methods
1252 addOn_ and removeOn_
1254 * genericparser.cs (GenericParser::error): Overloaded method to handle the case

1256 error reporting should be done through the Report object.
1258 * class.cs (TypeContainer.Indexers): New property to access the list of indexers.
1259 (Populate): Iterate thru the indexers we have and define them too.
1260 (Indexer.GetMethodBuilder, .SetMethodBuilder): New members to hold the method builders

1301 (CheckBinaryOperator): Same here.
1303 * rootcontext.cs (LookupType): Add an extra lookup which simply does a lookup
1304 on the name without any prefixes of namespace names etc. This is because we
1305 already might have something already fully qualified like
1306 'System.Console.WriteLine'

1310 2001-09-07 Ravi Pratap <ravi@ximian.com>

1732 generation from working. Also add some temporary debugging
1735 2001-08-24 Miguel de Icaza <miguel@ximian.com>
1737 * codegen.cs: Lots of code generation pieces. This is only the
1738 beginning, will continue tomorrow with more touches of polish. We

1812 track of static constructors; If none is used, turn on
1813 BeforeFieldInit in the TypeAttributes.

1816 for the cases where there are no arguments.
1818 (constructor_declarator): If there is no implicit `base' or

1888 * driver.cs: Make sure we always load mscorlib first (for
1889 debugging purposes, nothing really important).
1891 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1892 have moved to `CSC' rather than `CIR'. Oh man! The confussion!

1959 RecordInterface instead.
1961 * cs-parser.jay: Updated to reflect changes above.
1963 * decl.cs (Definition): Keep track of the TypeBuilder type that
1964 represents this type here. Not sure we will use it in the long
1965 run, but wont hurt for now.

2002 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
2005 Get rid of old crufty code.
2007 * rootcontext.cs: Use this to keep track of the parsed
2008 representation and the defined types available to the program.
2010 * gen-treedump.cs: adjust for new convention.
2012 * type.cs: Split out the type manager, and the assembly builder
2015 * typemanager.cs: the type manager will live here now.
2017 * cil-codegen.cs: And the code generator here.
2019 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
2021 * makefile: Fixed up for easy making.
2023 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2025 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
2028 (unary_expression): Expand pre_increment_expression and
2029 post_decrement_expression to reduce a shift/reduce.
2031 2001-07-11 Simon Cozens
2033 * cs-tokenizer.cs: Hex numbers should begin with a 0.
2035 Improve allow_keyword_as_indent name.
2037 2001-06-19 Miguel de Icaza <miguel@ximian.com>
2039 * Adjustments for Beta2.
2041 2001-06-13 Miguel de Icaza <miguel@ximian.com>
2043 * decl.cs: Added `Define' abstract method.
2044 (InTransit): new property, used to catch recursive definitions.
2046 * interface.cs: Implement `Define'.
2048 * modifiers.cs: Map Modifiers.constants to
2049 System.Reflection.TypeAttribute flags.
2051 * class.cs: Keep track of types and user-defined types.
2052 (BuilderInit): New method for creating an assembly
2053 (ResolveType): New function to launch the resolution process, only
2054 used by interfaces for now.
2056 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
2057 that are inserted into the name space.
2059 2001-06-08 Miguel de Icaza <miguel@ximian.com>
2061 * ARGH. I have screwed up my tree so many times due to the use of
2062 rsync rather than using CVS. Going to fix this at once.
2064 * driver.cs: Objetify driver. Load assemblies, use assemblies to
2067 2001-06-07 Miguel de Icaza <miguel@ximian.com>
2069 * Experiment successful: Use System.Type rather that our own
2072 2001-05-25 Miguel de Icaza <miguel@ximian.com>
2074 * cs-parser.jay: Removed nsAliases from here.
2076 Use new namespaces, handle `using XXX;'
2078 * namespace.cs: Reimplemented namespace handling, use a recursive
2079 definition of the class. Now we can keep track of using clauses
2080 and catch invalid using clauses.
2082 2001-05-24 Miguel de Icaza <miguel@ximian.com>
2084 * gen-treedump.cs: Adapted for all the renaming.
2086 * expression.cs (Expression): this class now has a Type property
2087 which returns an expression Type.
2089 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
2090 `Type', as this has a different meaning now in the base
2092 2001-05-22 Miguel de Icaza <miguel@ximian.com>
2094 * interface.cs, class.cs: Removed from all the sources the
2095 references to signature computation, as we can not do method
2096 signature computation during the parsing time, as we are not
2097 trying to solve at that point distinguishing:
2101 void a (NS.Blah x) {}
2104 Which depending on the context might be valid or not, as we do not
2105 know if Blah is the same thing as NS.Blah at that point.
2107 * Redid everything so the code uses TypeRefs now instead of
2108 Types. TypeRefs are just temporary type placeholders, that need
2109 to be resolved. They initially have a pointer to a string and the
2110 current scope in which they are used. This is used later by the
2111 compiler to resolve the reference to an actual Type.
2113 * DeclSpace is no longer a CIR.Type, and neither are
2114 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
2115 are all DeclSpaces, but no Types.
2117 * type.cs (TypeRefManager): This implements the TypeRef manager,
2118 which keeps track of all the types that need to be resolved after
2119 the parsing has finished.
2121 2001-05-13 Miguel de Icaza <miguel@ximian.com>
2123 * ARGH. We are going to have to store `foreach' as a class rather
2124 than resolving it, as we need to verify error 1579 after name
2125 resolution. *OR* we could keep a flag that says `This request to
2126 IEnumerator comes from a foreach statement' which we can then use
2127 to generate the error.
2129 2001-05-10 Miguel de Icaza <miguel@ximian.com>
2131 * class.cs (TypeContainer.AddMethod): we now add methods to the
2132 MethodGroup instead of the method hashtable.
2134 * expression.cs: Add MethodGroup abstraction, which gets us one
2135 step closer to the specification in the way we handle method
2138 * cs-parser.jay (primary_expression): qualified_identifier now
2139 tried to match up an identifier to a local variable reference or
2140 to a parameter reference.
2142 current_local_parameters is now a parser global variable that
2143 points to the current parameters for the block, used during name
2146 (property_declaration): Now creates an implicit `value' argument to
2149 2001-05-09 Miguel de Icaza <miguel@ximian.com>
2151 * parameter.cs: Do not use `param' arguments as part of the
2152 signature, per the spec.
2154 2001-05-08 Miguel de Icaza <miguel@ximian.com>
2156 * decl.cs: Base class for classes, structs and interfaces. This
2157 is the "Declaration Space"
2159 * cs-parser.jay: Use CheckDef for checking declaration errors
2160 instead of having one on each function.
2162 * class.cs: Factor out some code for handling error handling in
2163 accordance to the "Declarations" section in the "Basic Concepts"
2164 chapter in the ECMA C# spec.
2166 * interface.cs: Make all interface member classes derive from
2167 InterfaceMemberBase.
2169 2001-05-07 Miguel de Icaza <miguel@ximian.com>
2171 * Many things: all interfaces are parsed and generated in
2172 gen-treedump. Support for member variables, constructors,
2173 destructors, properties, constants is there.
2175 Beginning of the IL backend, but very little done, just there for
2178 2001-04-29 Miguel de Icaza <miguel@ximian.com>
2180 * cs-parser.jay: Fix labeled statement.
2182 * cs-tokenizer.cs (escape): Escape " and ' always.
2183 ref_line, ref_name: keep track of the line/filename as instructed
2184 by #line by the compiler.
2187 2001-04-27 Miguel de Icaza <miguel@ximian.com>
2189 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
2190 to match the values in System.CodeDOM.
2192 Divid renamed to Divide.
2194 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
2196 (Statements.set): remove.
2198 * System.CodeDOM/CodeCatchClause.cs: always have a valid
2201 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
2202 falseStatements always have valid values.
2204 * cs-parser.jay: Use System.CodeDOM now.
