1 2001-10-07 Miguel de Icaza <miguel@ximian.com>
3 * expression.cs (UserCast): This user cast was not really doing
4 what it was supposed to do. Which is to be born in fully resolved
5 state. Parts of the resolution were being performed at Emit time!
9 2001-10-05 Miguel de Icaza <miguel@ximian.com>
11 * expression.cs: Implicity convert the result from UserCast.
13 2001-10-05 Ravi Pratap <ravi@ximian.com>
15 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
16 prevented it from working correctly.

19 merely ConvertImplicit.
21 2001-10-05 Miguel de Icaza <miguel@ximian.com>
23 * typemanager.cs: Make the LookupTypeContainer function static,
26 * class.cs: Make static FindMembers (the one that takes a Type
29 * codegen.cs: Add EmitForeach here.
31 * cs-parser.jay: Make foreach a toplevel object instead of the
32 inline expansion, as we need to perform semantic analysis on it.
34 2001-10-05 Ravi Pratap <ravi@ximian.com>
36 * expression.cs (Expression::ImplicitUserConversion): Rename to
37 UserDefinedConversion.
39 (Expression::UserDefinedConversion): Take an extra argument specifying
40 whether we look for explicit user conversions too.
42 (Expression::ImplicitUserConversion): Make it a call to UserDefinedConversion.
44 (UserDefinedConversion): Incorporate support for user defined explicit conversions.
46 (ExplicitUserConversion): Make it a call to UserDefinedConversion
47 with the appropriate arguments.

51 * expression.cs (Cast): Record location info.
53 (Expression::ConvertExplicit): Take location argument.
55 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
56 to determine if we are doing explicit conversions.

60 (Expression::ConvertExplicit): Report an error if everything fails.
62 * ../errors/cs0030.cs : Add.
64 2001-10-04 Miguel de Icaza <miguel@ximian.com>
66 * modifiers.cs: If the ABSTRACT keyword is present, also set the
67 virtual and newslot bits.
69 * class.cs (TypeContainer::RegisterRequiredImplementations):
70 Record methods we need.
72 (TypeContainer::MakeKey): Helper function to make keys for
73 MethodBases, since the Methodbase key is useless.
75 (TypeContainer::Populate): Call RegisterRequiredImplementations
76 before defining the methods.
78 Create a mapping for method_builders_to_methods ahead of time
79 instead of inside a tight loop.
81 (::RequireMethods): Accept an object as the data to set into the
82 hashtable so we can report interface vs abstract method mismatch.
84 2001-10-03 Miguel de Icaza <miguel@ximian.com>
86 * report.cs: Make all of it static.
88 * rootcontext.cs: Drop object_type and value_type computations, as
89 we have those in the TypeManager anyways.
91 Drop report instance variable too, now it is a global.
93 * driver.cs: Use try/catch on command line handling.
95 Add --probe option to debug the error reporting system with a test
98 * report.cs: Add support for exiting program when a probe
101 2001-10-03 Ravi Pratap <ravi@ximian.com>
103 * expression.cs (Binary::DoNumericPromotions): Fix the case when
104 we do a forcible conversion regardless of type, to check if
105 ForceConversion returns a null.
107 (Binary::error19): Use location to report error.
109 (Unary::error23): Use location here too.
111 * ../errors/cs0019.cs : Check in.
113 * ../errors/cs0023.cs : Check in.
115 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
116 case of a non-null MethodInfo object with a length of 0 !
118 (Binary::ResolveOperator): Flag error if overload resolution fails to find
119 an applicable member - according to the spec :-)
120 Also fix logic to find members in base types.
122 (Unary::ResolveOperator): Same here.
124 (Unary::report23): Change name to error23 and make first argument a TypeContainer
125 as I was getting thoroughly confused between this and error19 :-)
127 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
128 (::FindMostEncompassedType): Implement.
129 (::FindMostEncompassingType): Implement.
130 (::StandardConversionExists): Implement.
132 (UserImplicitCast): Re-vamp. We now need info about most specific
133 source and target types so that we can do the necessary conversions.
135 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
136 mathematical union with no duplicates.
138 2001-10-03 Miguel de Icaza <miguel@ximian.com>
140 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
141 in order from base classes to child classes, so that we can in
142 child classes look up in our parent for method names and
143 attributes (required for handling abstract, virtual, new, override
144 constructs: we need to instrospect our base class, and if we dont
145 populate the classes in order, the introspection might be
146 incorrect. For example, a method could query its parent before
147 the parent has any methods and would determine that the parent has
148 no abstract methods (while it could have had them)).
150 (RootContext::CreateType): Record the order in which we define the
153 2001-10-02 Miguel de Icaza <miguel@ximian.com>
155 * class.cs (TypeContainer::Populate): Also method definitions can
156 fail now, keep track of this.

159 DeclaredOnly/noDeclaredOnly flag.
161 (Constructor::Emit) Return the ConstructorBuilder.
163 (Method::Emit) Return the MethodBuilder.
164 Check for abstract or virtual methods to be public.
166 * rootcontext.cs (RootContext::CreateType): Register all the
167 abstract methods required for the class to be complete and the
168 interface methods that must be implemented.
170 * cs-parser.jay: Report error 501 (method requires body if it is
171 not marked abstract or extern).
173 * expression.cs (TypeOf::Emit): Implement.
175 * typemanager.cs: runtime_handle_type, new global type.
177 * class.cs (Property::Emit): Generate code for properties.
179 2001-10-02 Ravi Pratap <ravi@ximian.com>
181 * expression.cs (Unary::ResolveOperator): Find operators on base type
182 too - we now conform exactly to the spec.
184 (Binary::ResolveOperator): Same here.
186 * class.cs (Operator::Define): Fix minor quirk in the tests.
188 * ../errors/cs0215.cs : Added.
190 * ../errors/cs0556.cs : Added.
192 * ../errors/cs0555.cs : Added.
194 2001-10-01 Miguel de Icaza <miguel@ximian.com>
196 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
197 single integer which is really efficient
199 2001-10-01 Ravi Pratap <ravi@ximian.com>
201 * expression.cs (Expression::ImplicitUserConversion): Use location
202 even in the case when we are examining True operators.
204 * class.cs (Operator::Define): Perform extensive checks to conform
205 with the rules for operator overloading in the spec.
207 * expression.cs (Expression::ImplicitReferenceConversion): Implement
208 some of the other conversions mentioned in the spec.

216 we start resolving the tree and populating types.
218 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
220 2001-10-01 Miguel de Icaza <miguel@ximian.com>
222 * expression.cs (Expression::ExprClassFromMemberInfo,
223 Expression::Literalize): Create literal expressions from
224 FieldInfos which are literals.
226 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
227 type casts, because they were wrong. The test suite in tests
230 (ImplicitNumericConversion): ushort to ulong requires a widening
233 Int32 constant to long requires widening cast as well.
235 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
236 for integers because the type on the stack is not i4.
238 2001-09-30 Miguel de Icaza <miguel@ximian.com>
240 * expression.cs (report118): require location argument.
242 * parameter.cs: Do not dereference potential null value.
244 * class.cs: Catch methods that lack the `new' keyword when
245 overriding a name. Report warnings when `new' is used without
246 anything being there to override.
248 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
250 * class.cs: Only add constructor to hashtable if it is non-null
251 (as now constructors can fail on define).
253 (TypeManager, Class, Struct): Take location arguments.
255 Catch field instance initialization in structs as errors.
257 accepting_filter: a new filter for FindMembers that is static so
258 that we dont create an instance per invocation.
260 (Constructor::Define): Catch errors where a struct constructor is
263 * cs-parser.jay: Pass location information for various new
266 * delegate.cs (Delegate): take a location argument.
268 * driver.cs: Do not call EmitCode if there were problesm in the
269 Definition of the types, as many Builders wont be there.
271 * decl.cs (Decl::Decl): Require a location argument.
273 * cs-tokenizer.cs: Handle properly hex constants that can not fit
274 into integers, and find the most appropiate integer for it.
276 * literal.cs: Implement ULongLiteral.
278 * rootcontext.cs: Provide better information about the location of
279 failure when CreateType fails.
281 2001-09-29 Miguel de Icaza <miguel@ximian.com>
283 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
286 * expression.cs (Binary::CheckShiftArguments): Add missing type
288 (Binary::ResolveOperator): Add type to the logical and and logical
289 or, Bitwise And/Or and Exclusive Or code paths, it was missing
292 (Binary::DoNumericPromotions): In the case where either argument
293 is ulong (and most signed types combined with ulong cause an
294 error) perform implicit integer constant conversions as well.
296 2001-09-28 Miguel de Icaza <miguel@ximian.com>
298 * expression.cs (UserImplicitCast): Method should always be
300 (Invocation::BetterConversion): Simplified test for IntLiteral.
302 (Expression::ImplicitNumericConversion): Split this routine out.
303 Put the code that performs implicit constant integer conversions
306 (Expression::Resolve): Become a wrapper around DoResolve so we can
307 check eclass and type being set after resolve.
309 (Invocation::Badness): Remove this dead function
311 (Binary::ResolveOperator): Do not compute the expensive argumnets
312 unless we have a union for it.
314 (Probe::Emit): Is needs to do an isinst and then
315 compare against null.
317 (::CanConvert): Added Location argument. If the Location argument
318 is null (Location.Null), then we do not report errors. This is
319 used by the `probe' mechanism of the Explicit conversion. We do
320 not want to generate an error for something that the user
321 explicitly requested to be casted. But the pipeline for an
322 explicit cast first tests for potential implicit casts.
324 So for now, if the Location is null, it means `Probe only' to
325 avoid adding another argument. Might have to revise this
328 (ClassCast): New class used to type cast objects into arbitrary
329 classes (used in Explicit Reference Conversions).
331 Implement `as' as well.
333 Reverted all the patches from Ravi below: they were broken:
335 * The use of `level' as a mechanism to stop recursive
336 invocations is wrong. That was there just to catch the
337 bug with a strack trace but not as a way of addressing
340 To fix the problem we have to *understand* what is going
341 on and the interactions and come up with a plan, not
342 just get things going.
344 * The use of the type conversion cache that I proposed
345 last night had an open topic: How does this work across
346 protection domains. A user defined conversion might not
347 be public in the location where we are applying the
348 conversion, a different conversion might be selected
349 (ie, private A->B (better) but public B->A (worse),
350 inside A, A->B applies, but outside it, B->A will
353 * On top of that (ie, even if the above is solved),
354 conversions in a cache need to be abstract. Ie, `To
355 convert from an Int to a Short use an OpcodeCast', not
356 `To convert from an Int to a Short use the OpcodeCast on
357 the variable 5' (which is what this patch was doing).
359 2001-09-28 Ravi Pratap <ravi@ximian.com>
361 * expression.cs (Invocation::ConversionExists): Re-write to use
364 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
365 cache all conversions done, not just user-defined ones.
367 (Invocation::BetterConversion): The real culprit. Use ConversionExists
368 to determine if a conversion exists instead of acutually trying to
369 perform the conversion. It's faster too.
371 (Expression::ConvertExplicit): Modify to use ConversionExists to check
372 and only then attempt the implicit conversion.
374 2001-09-28 Ravi Pratap <ravi@ximian.com>
376 * expression.cs (ConvertImplicit): Use a cache for conversions
377 already found. Check level of recursion and bail out if necessary.
379 2001-09-28 Miguel de Icaza <miguel@ximian.com>
381 * typemanager.cs (string_concat_string_string, string_concat_object_object):
382 Export standard methods that we expect for string operations.
384 * statement.cs (Block::UsageWarning): Track usage of variables and
385 report the errors for not used variables.
387 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
390 2001-09-27 Miguel de Icaza <miguel@ximian.com>
392 * codegen.cs: remove unnneded code
394 * expression.cs: Removed BuiltinTypeAccess class
396 Fix the order in which implicit conversions are
399 The previous fixed dropped support for boxed conversions (adding a
400 test to the test suite now)
402 (UserImplicitCast::CanConvert): Remove test for source being null,
403 that code is broken. We should not feed a null to begin with, if
404 we do, then we should track the bug where the problem originates
405 and not try to cover it up here.
407 Return a resolved expression of type UserImplicitCast on success
408 rather than true/false. Ravi: this is what I was talking about,
409 the pattern is to use a static method as a "constructor" for
412 Also, do not create arguments until the very last minute,
413 otherwise we always create the arguments even for lookups that
414 will never be performed.
416 (UserImplicitCast::Resolve): Eliminate, objects of type
417 UserImplicitCast are born in a fully resolved state.
419 * typemanager.cs (InitCoreTypes): Init also value_type
422 * expression.cs (Cast::Resolve): First resolve the child expression.
424 (LValue): Add new method AddressOf to be used by
427 Change the argument of Store to take an EmitContext instead of an
428 ILGenerator, because things like FieldExpr need to be able to call
429 their children expression to generate the instance code.
431 (Expression::Error, Expression::Warning): Sugar functions for
434 (Expression::MemberLookup): Accept a TypeContainer instead of a
435 Report as the first argument.
437 (Expression::ResolvePrimary): Killed. I still want to improve
438 this as currently the code is just not right.
440 (Expression::ResolveMemberAccess): Simplify, but it is still
443 (Unary::Resolve): Catch errors in AddressOf operators.
445 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
446 index to a byte for the short-version, or the compiler will choose
447 the wrong Emit call, which generates the wrong data.
449 (ParameterReference::Emit, ::Store): same.
451 (FieldExpr::AddressOf): Implement.
453 * typemanager.cs: TypeManager: made public variable instead of
456 * driver.cs: document --fatal.
458 * report.cs (ErrorMessage, WarningMessage): new names for the old
459 Error and Warning classes.
461 * cs-parser.jay (member_access): Turn built-in access to types
462 into a normal simplename
464 2001-09-27 Ravi Pratap <ravi@ximian.com>
466 * expression.cs (Invocation::BetterConversion): Fix to cope
467 with q being null, since this was introducing a bug.
469 * expression.cs (ConvertImplicit): Do built-in conversions first.
471 2001-09-27 Ravi Pratap <ravi@ximian.com>
473 * expression.cs (UserImplicitCast::Resolve): Fix bug.

477 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
478 I had introduced long ago (what's new ?).
480 * expression.cs (UserImplicitCast::CanConvert): Static method to do
481 the work of all the checking.
482 (ConvertImplicit): Call CanConvert and only then create object if necessary.
483 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
485 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
486 that is the right way.
488 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
489 overloading resolution. Use everywhere instead of cutting and pasting code.
491 (Binary::ResolveOperator): Use MakeUnionSet.
493 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
494 we have to convert to bool types. Not complete yet.
496 2001-09-27 Miguel de Icaza <miguel@ximian.com>
498 * typemanager.cs (TypeManager::CSharpName): support ushort.
500 * expression.cs (Expression::TryImplicitIntConversion): Attempts
501 to provide an expression that performsn an implicit constant int
502 conversion (section 6.1.6).
503 (Expression::ConvertImplicitRequired): Reworked to include
504 implicit constant expression conversions.
506 (Expression::ConvertNumericExplicit): Finished.
508 (Invocation::Emit): If InstanceExpression is null, then it means
509 that we perform a call on this.
511 2001-09-26 Miguel de Icaza <miguel@ximian.com>
513 * expression.cs (Unary::Emit): Remove some dead code.
514 (Probe): Implement Resolve and Emit for `is'.
515 (Expression::ConvertImplicitRequired): Attempt to do constant
516 expression conversions here. Maybe should be moved to
517 ConvertImplicit, but I am not sure.
518 (Expression::ImplicitLongConstantConversionPossible,
519 Expression::ImplicitIntConstantConversionPossible): New functions
520 that tell whether is it possible to apply an implicit constant
521 expression conversion.
523 (ConvertNumericExplicit): Started work on explicit numeric
526 * cs-parser.jay: Update operator constants.
528 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
529 (Parameters::GetSignature): Hook up VerifyArgs here.
530 (Parameters::VerifyArgs): Verifies that no two arguments have the
533 * class.cs (Operator): Update the operator names to reflect the
534 ones that the spec expects (as we are just stringizing the
537 * expression.cs (Unary::ResolveOperator): Fix bug: Use
538 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
539 previous usage did only work for our methods.
540 (Expression::ConvertImplicit): Handle decimal implicit numeric
542 (Expression::InternalTypeConstructor): Used to invoke constructors
543 on internal types for default promotions.
545 (Unary::Emit): Implement special handling for the pre/post
546 increment/decrement for overloaded operators, as they need to have
547 the same semantics as the other operators.
549 (Binary::ResolveOperator): ditto.
550 (Invocation::ConversionExists): ditto.
551 (UserImplicitCast::Resolve): ditto.
553 2001-09-26 Ravi Pratap <ravi@ximian.com>

567 * assign.cs (Assign): Make it inherit from ExpressionStatement.
569 * expression.cs (ExpressionStatement): New base class used for
570 expressions that can appear in statements, so that we can provide
571 an alternate path to generate expression that do not leave a value
574 (Expression::Emit, and all the derivatives): We no longer return
575 whether a value is left on the stack or not. Every expression
576 after being emitted leaves a single value on the stack.
578 * codegen.cs (EmitContext::EmitStatementExpression): Use the
579 facilties of ExpressionStatement if possible.
581 * cs-parser.jay: Update statement_expression.
583 2001-09-25 Miguel de Icaza <miguel@ximian.com>

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

606 * assign.cs: track location.
607 (Resolve): Use implicit conversions on assignment.
609 * literal.cs: Oops. Not good, Emit of short access values should
610 pass (Bytes) or the wrong argument will be selected.
612 * expression.cs (Unary::Emit): Emit code for -expr.
614 (Unary::ResolveOperator): Handle `Substract' for non-constants
615 (substract from zero from the non-constants).
616 Deal with Doubles as well.
618 (Expression::ConvertImplicitRequired): New routine that reports an
619 error if no implicit conversion exists.
621 (Invocation::OverloadResolve): Store the converted implicit
622 expressions if we make them

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

672 * typemanager.cs: declare and load enum_type, delegate_type and
675 * expression.cs (Expression::Emit): Now emit returns a value that
676 tells whether a value is left on the stack or not. This strategy
677 might be reveted tomorrow with a mechanism that would address
678 multiple assignments.
679 (Expression::report118): Utility routine to report mismatches on
682 (Unary::Report23): Report impossible type/operator combination
685 (Unary::IsIncrementableNumber): Whether the type can be
686 incremented or decremented with add.
687 (Unary::ResolveOperator): Also allow enumerations to be bitwise
689 (Unary::ResolveOperator): Implement ++, !, ~, ++ and --.
691 (Invocation::Emit): Deal with new Emit convetion.
693 * All Expression derivatives: Updated their Emit method to return
694 whether they leave values on the stack or not.
696 * codegen.cs (CodeGen::EmitStatement): Pop values left on the
697 stack for expressions that are statements.
699 2001-09-20 Miguel de Icaza <miguel@ximian.com>
701 * expression.cs (LValue): New interface. Must be implemented by
703 (LocalVariableReference, ParameterReference, FieldExpr): Implement
706 * assign.cs (Assign::Emit, Assign::Resolve): Use new LValue
707 interface for generating code, simplifies the code.
709 2001-09-20 Ravi Pratap <ravi@ximian.com>

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

743 2001-09-19 Miguel de Icaza <miguel@ximian.com>

750 expression for expressions which are just +expr.

775 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
776 operators are found instead of making noise ;-)
777 (Unary::ResolveOperator): New method to do precisely the same thing which
778 Binary::ResolveOperator does for Binary expressions.
779 (Unary.method, .Arguments): Add.
780 (Unary::OperName): Implement.
781 (Unary::ForceConversion): Copy and Paste !
783 * class.cs (Operator::Define): Fix a small bug for the case when we have
786 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
787 for the inbuilt operators. Only overloading works for now ;-)

807 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
808 the last instruction contains a return opcode to avoid generating
809 the last `ret' instruction (this generates correct code, and it is
810 nice to pass the peverify output).
812 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
813 initializer for static and instance variables.
814 (Constructor::Emit): Allow initializer to be null in the case of
815 static constructors. Only emit initializer for instance
818 (TypeContainer::FindMembers): Return a null array if there are no
821 Also fix the code for the MemberTypes.Method branch, as it was not
822 scanning that for operators (or tried to access null variables before).

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

868 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
871 (Expression::MemberLookup): Provide a version that allows to
872 specify the MemberTypes and BindingFlags.
874 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,

885 deal with this by semantically definining it as if the user had
888 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
889 constructors as we now "emit" them at a higher level.
891 (TypeContainer::DefineDefaultConstructor): Used to define the

911 * rootcontext.cs (IsNameSpace): Compare against null.

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

981 have to cope with the

985 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
986 FamORAssem, not FamANDAssem.

990 * driver.cs: Added --parse option that only parses its input files
993 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
994 incorrect. IsTopLevel is not used to tell whether an object is
995 root_types or not (that can be achieved by testing this ==
996 root_types). But to see if this is a top-level *class* (not
997 necessarly our "toplevel" container).
999 2001-09-14 Ravi Pratap <ravi@ximian.com>
1001 * enum.cs (Enum::Define): Modify to call the Lookup method on the

1006 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
1007 Modifiers.TypeAttr. This should just be a call to that method.
1009 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
1010 object so that we can determine if we are top-level or not.
1012 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
1015 * enum.cs (Enum::Define): Ditto.
1017 * modifiers.cs (FieldAttr): Re-write.

1020 (TypeContainer::HaveStaticConstructor): New property to provide access
1021 to precisely that info.
1023 * modifiers.cs (MethodAttr): Re-write.
1024 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
1026 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent

1029 2001-09-13 Miguel de Icaza <miguel@ximian.com>
1031 * expression.cs (MemberLookup): Fruitless attempt to lookup
1032 constructors. Maybe I need to emit default constructors? That
1033 might be it (currently .NET emits this for me automatically).
1034 (Invocation::OverloadResolve): Cope with Arguments == null.
1035 (Invocation::EmitArguments): new function, shared by the new

1049 SimpleLookup): Auxiliary routines to help parse a qualifier
1052 Update qualifier_identifier rule.
1054 * codegen.cs: Removed debugging messages.

1057 objects that we might have around.
1059 (Populate): Only initialize method_builders_to_methods once.
1061 * expression.cs (PropertyExpr): Initialize type from the
1064 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

1069 (Binary::ResolveOperator): Set the return type to boolean for
1070 comparission operators
1072 * typemanager.cs: Remove debugging print code.
1074 (Invocation::Resolve): resolve type.
1076 * class.cs: Allocate a MemberInfo of the correct size, as the code
1077 elsewhere depends on the test to reflect the correct contents.
1079 (Method::) Keep track of parameters, due to System.Reflection holes
1081 (TypeContainer::Populate): Keep track of MethodBuilders to Method
1084 (TypeContainer::FindMembers): Use ArrayList and then copy an array
1085 of the exact size and return that.
1087 (Class::LookupMethodByBuilder): New function that maps
1088 MethodBuilders to its methods. Required to locate the information
1089 on methods because System.Reflection bit us again.
1091 * support.cs: New file, contains an interface ParameterData and
1092 two implementations: ReflectionParameters and InternalParameters
1093 used to access Parameter information. We will need to grow this
1096 * expression.cs (Invocation::GetParameterData): implement a cache
1097 and a wrapper around the ParameterData creation for methods.
1098 (Invocation::OverloadResolve): Use new code.
1100 2001-09-13 Ravi Pratap <ravi@ximian.com>

1105 (TypeContainer::Populate): Update accordingly.
1106 (TypeContainer::FindMembers): Implement.
1108 2001-09-13 Miguel de Icaza <miguel@ximian.com>

1154 2001-09-12 Ravi Pratap <ravi@ximian.com>
1156 * class.cs (TypeContainer::FindMembers): Method which does exactly
1157 what Type.FindMembers does, only we don't have to use reflection. No

1161 typecontainer objects as we need to get at them.
1162 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

1190 (Property::Define): Ditto.

1204 addOn_ and removeOn_
1206 * genericparser.cs (GenericParser::error): Overloaded method to handle the case

1257 already might have something already fully qualified like

1262 2001-09-07 Ravi Pratap <ravi@ximian.com>

1684 generation from working. Also add some temporary debugging
1687 2001-08-24 Miguel de Icaza <miguel@ximian.com>

1764 track of static constructors; If none is used, turn on
1765 BeforeFieldInit in the TypeAttributes.

1841 debugging purposes, nothing really important).
1843 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1844 have moved to `CSC' rather than `CIR'. Oh man! The confussion!

1911 RecordInterface instead.
1913 * cs-parser.jay: Updated to reflect changes above.
1915 * decl.cs (Definition): Keep track of the TypeBuilder type that
1916 represents this type here. Not sure we will use it in the long

2003 * class.cs: Keep track of types and user-defined types.
2004 (BuilderInit): New method for creating an assembly
2005 (ResolveType): New function to launch the resolution process, only
2006 used by interfaces for now.
2008 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
2009 that are inserted into the name space.
2011 2001-06-08 Miguel de Icaza <miguel@ximian.com>
2013 * ARGH. I have screwed up my tree so many times due to the use of
2014 rsync rather than using CVS. Going to fix this at once.
2016 * driver.cs: Objetify driver. Load assemblies, use assemblies to
2019 2001-06-07 Miguel de Icaza <miguel@ximian.com>
2021 * Experiment successful: Use System.Type rather that our own
2024 2001-05-25 Miguel de Icaza <miguel@ximian.com>
2026 * cs-parser.jay: Removed nsAliases from here.
2028 Use new namespaces, handle `using XXX;'
2030 * namespace.cs: Reimplemented namespace handling, use a recursive
2031 definition of the class. Now we can keep track of using clauses
2032 and catch invalid using clauses.
2034 2001-05-24 Miguel de Icaza <miguel@ximian.com>
2036 * gen-treedump.cs: Adapted for all the renaming.
2038 * expression.cs (Expression): this class now has a Type property
2039 which returns an expression Type.
2041 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
2042 `Type', as this has a different meaning now in the base
2044 2001-05-22 Miguel de Icaza <miguel@ximian.com>
2046 * interface.cs, class.cs: Removed from all the sources the
2047 references to signature computation, as we can not do method
2048 signature computation during the parsing time, as we are not
2049 trying to solve at that point distinguishing:
2053 void a (NS.Blah x) {}
2056 Which depending on the context might be valid or not, as we do not
2057 know if Blah is the same thing as NS.Blah at that point.
2059 * Redid everything so the code uses TypeRefs now instead of
2060 Types. TypeRefs are just temporary type placeholders, that need
2061 to be resolved. They initially have a pointer to a string and the
2062 current scope in which they are used. This is used later by the
2063 compiler to resolve the reference to an actual Type.
2065 * DeclSpace is no longer a CIR.Type, and neither are
2066 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
2067 are all DeclSpaces, but no Types.
2069 * type.cs (TypeRefManager): This implements the TypeRef manager,
2070 which keeps track of all the types that need to be resolved after
2071 the parsing has finished.
2073 2001-05-13 Miguel de Icaza <miguel@ximian.com>
2075 * ARGH. We are going to have to store `foreach' as a class rather
2076 than resolving it, as we need to verify error 1579 after name
2077 resolution. *OR* we could keep a flag that says `This request to
2078 IEnumerator comes from a foreach statement' which we can then use
2079 to generate the error.
2081 2001-05-10 Miguel de Icaza <miguel@ximian.com>
2083 * class.cs (TypeContainer.AddMethod): we now add methods to the
2084 MethodGroup instead of the method hashtable.
2086 * expression.cs: Add MethodGroup abstraction, which gets us one
2087 step closer to the specification in the way we handle method
2090 * cs-parser.jay (primary_expression): qualified_identifier now
2091 tried to match up an identifier to a local variable reference or
2092 to a parameter reference.
2094 current_local_parameters is now a parser global variable that
2095 points to the current parameters for the block, used during name
2098 (property_declaration): Now creates an implicit `value' argument to
2101 2001-05-09 Miguel de Icaza <miguel@ximian.com>
2103 * parameter.cs: Do not use `param' arguments as part of the
2104 signature, per the spec.
2106 2001-05-08 Miguel de Icaza <miguel@ximian.com>
2108 * decl.cs: Base class for classes, structs and interfaces. This
2109 is the "Declaration Space"
2111 * cs-parser.jay: Use CheckDef for checking declaration errors
2112 instead of having one on each function.
2114 * class.cs: Factor out some code for handling error handling in
2115 accordance to the "Declarations" section in the "Basic Concepts"
2116 chapter in the ECMA C# spec.
2118 * interface.cs: Make all interface member classes derive from
2119 InterfaceMemberBase.
2121 2001-05-07 Miguel de Icaza <miguel@ximian.com>
2123 * Many things: all interfaces are parsed and generated in
2124 gen-treedump. Support for member variables, constructors,
2125 destructors, properties, constants is there.
2127 Beginning of the IL backend, but very little done, just there for
2130 2001-04-29 Miguel de Icaza <miguel@ximian.com>
2132 * cs-parser.jay: Fix labeled statement.
2134 * cs-tokenizer.cs (escape): Escape " and ' always.
2135 ref_line, ref_name: keep track of the line/filename as instructed
2136 by #line by the compiler.
2139 2001-04-27 Miguel de Icaza <miguel@ximian.com>
2141 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
2142 to match the values in System.CodeDOM.
2144 Divid renamed to Divide.
2146 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
2148 (Statements.set): remove.
2150 * System.CodeDOM/CodeCatchClause.cs: always have a valid
2153 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
2154 falseStatements always have valid values.
2156 * cs-parser.jay: Use System.CodeDOM now.
