1 2001-10-11 Miguel de Icaza <miguel@ximian.com>
3 * expression.cs (Invocation::Emit): Deal with invocation of
4 methods on value types. We need to pass the address to structure
5 methods rather than the object itself. (The equivalent code to
6 emit "this" for structures leaves the entire structure on the
7 stack instead of a pointer to it).
9 (ParameterReference::DoResolve): Compute the real index for the
10 argument based on whether the method takes or not a `this' pointer
11 (ie, the method is static).
13 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store
14 value types returned from functions when we need to invoke a
15 method on the sturcture.
18 2001-10-11 Ravi Pratap <ravi@ximian.com>
20 * class.cs (TypeContainer::DefineType): Method to actually do the business of
21 defining the type in the Modulebuilder or Typebuilder. This is to take
22 care of nested types which need to be defined on the TypeBuilder using
25 (TypeContainer::GetClassBases): Implement. Essentially the code from the
26 methods in RootContext, only ported to be part of TypeContainer.
28 (TypeContainer::GetInterfaceOrClass): Ditto.
30 (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
32 * interface.cs (Interface::DefineInterface): New method. Does exactly
33 what RootContext.CreateInterface did earlier, only it takes care of nested types
36 (Interface::GetInterfaces): Move from RootContext here and port.
38 (Interface::GetInterfaceByName): Same here.
40 * rootcontext.cs (ResolveTree): Re-write.
42 (PopulateTypes): Re-write.
44 * class.cs (TypeContainer::Populate): Populate nested types too.
45 (TypeContainer::Emit): Emit nested members too.
47 * typemanager.cs (AddUserType): Do not make use of the FullName property,
48 instead just use the name argument passed in as it is already fully
51 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
52 to TypeContainer mapping to see if a type is user-defined.
54 * class.cs (TypeContainer::CloseType): Implement.
56 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
57 the default constructor.
59 (TypeContainer::Populate): Fix minor bug which led to creating default constructors
62 (Constructor::IsDefault): Fix up logic to determine if it is the default constructor
64 * interface.cs (CloseType): Create the type here.
66 * rootcontext.cs (CloseTypes): Re-write to recursively close types by running through
69 Remove all the methods which are now in TypeContainer.
71 2001-10-10 Ravi Pratap <ravi@ximian.com>
73 * delegate.cs (Define): Re-write bits to define the delegate
76 2001-10-10 Miguel de Icaza <miguel@ximian.com>
78 * makefile: Renamed the compiler to `mcs.exe' instead of compiler.exe
80 * expression.cs (ImplicitReferenceConversion): handle null as well
81 as a source to convert to any reference type.
83 * statement.cs (Return): Perform any implicit conversions to
86 Validate use of return statement.
88 * codegen.cs (EmitContext): Pass the expected return type here.
90 * class.cs (Method, Constructor, Property): Pass expected return
93 2001-10-09 Miguel de Icaza <miguel@ximian.com>
95 * expression.cs: Make DoResolve take an EmitContext instead of a
98 Replaced `l' and `location' for `loc', for consistency.
100 (Error, Warning): Remove unneeded Tc argument.
102 * assign.cs, literal.cs, constant.cs: Update to new calling
105 * codegen.cs: EmitContext now contains a flag indicating whether
106 code is being generated in a static method or not.
108 * cs-parser.jay: DecomposeQI, new function that replaces the old
109 QualifiedIdentifier. Now we always decompose the assembled
110 strings from qualified_identifier productions into a group of
113 2001-10-08 Miguel de Icaza <miguel@ximian.com>
115 * rootcontext.cs: Deal with field-less struct types correctly now
116 by passing the size option to Define Type.
118 * class.cs: Removed hack that created one static field.
120 2001-10-07 Miguel de Icaza <miguel@ximian.com>
122 * statement.cs: Moved most of the code generation here.
124 2001-10-09 Ravi Pratap <ravi@ximian.com>
126 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
129 (ElementAccess): Remove useless bits for now - keep checks as the spec
132 2001-10-08 Ravi Pratap <ravi@ximian.com>
134 * expression.cs (ElementAccess::DoResolve): Remove my crap code
135 and start performing checks according to the spec.
137 2001-10-07 Ravi Pratap <ravi@ximian.com>
139 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
140 rank_specifiers instead.
142 (rank_specifiers): Change the order in which the rank specifiers are stored
144 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
146 * expression.cs (ElementAccess): Implement the LValue interface too.
148 2001-10-06 Ravi Pratap <ravi@ximian.com>
150 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
151 except that user defined conversions are not included.
153 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
154 perform the conversion of the return type, if necessary.
156 (New::DoResolve): Check whether we are creating an array or an object
157 and accordingly do the needful.
159 (New::Emit): Same here.
161 (New::DoResolve): Implement guts of array creation.
163 (New::FormLookupType): Helper function.
165 2001-10-07 Miguel de Icaza <miguel@ximian.com>
167 * codegen.cs: Removed most of the code generation here, and move the
168 corresponding code generation bits to the statement classes.
170 Added support for try/catch/finalize and throw.
172 * cs-parser.jay: Added support for try/catch/finalize.
174 * class.cs: Catch static methods having the flags override,
177 * expression.cs (UserCast): This user cast was not really doing
178 what it was supposed to do. Which is to be born in fully resolved
179 state. Parts of the resolution were being performed at Emit time!
183 2001-10-05 Miguel de Icaza <miguel@ximian.com>
185 * expression.cs: Implicity convert the result from UserCast.
187 2001-10-05 Ravi Pratap <ravi@ximian.com>
189 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
190 prevented it from working correctly.
192 (ConvertExplicit): Make the first try, a call to ConvertImplicitStandard, not
193 merely ConvertImplicit.
195 2001-10-05 Miguel de Icaza <miguel@ximian.com>
197 * typemanager.cs: Make the LookupTypeContainer function static,
198 and not per-instance.
200 * class.cs: Make static FindMembers (the one that takes a Type
203 * codegen.cs: Add EmitForeach here.
205 * cs-parser.jay: Make foreach a toplevel object instead of the
206 inline expansion, as we need to perform semantic analysis on it.
208 2001-10-05 Ravi Pratap <ravi@ximian.com>
210 * expression.cs (Expression::ImplicitUserConversion): Rename to
211 UserDefinedConversion.
213 (Expression::UserDefinedConversion): Take an extra argument specifying
214 whether we look for explicit user conversions too.
216 (Expression::ImplicitUserConversion): Make it a call to UserDefinedConversion.
218 (UserDefinedConversion): Incorporate support for user defined explicit conversions.
220 (ExplicitUserConversion): Make it a call to UserDefinedConversion
221 with the appropriate arguments.
223 * cs-parser.jay (cast_expression): Record location too.
225 * expression.cs (Cast): Record location info.
227 (Expression::ConvertExplicit): Take location argument.
229 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
230 to determine if we are doing explicit conversions.
232 (UserCast::Emit): Update accordingly.
234 (Expression::ConvertExplicit): Report an error if everything fails.
236 * ../errors/cs0030.cs : Add.
238 2001-10-04 Miguel de Icaza <miguel@ximian.com>
240 * modifiers.cs: If the ABSTRACT keyword is present, also set the
241 virtual and newslot bits.
243 * class.cs (TypeContainer::RegisterRequiredImplementations):
244 Record methods we need.
246 (TypeContainer::MakeKey): Helper function to make keys for
247 MethodBases, since the Methodbase key is useless.
249 (TypeContainer::Populate): Call RegisterRequiredImplementations
250 before defining the methods.
252 Create a mapping for method_builders_to_methods ahead of time
253 instead of inside a tight loop.
255 (::RequireMethods): Accept an object as the data to set into the
256 hashtable so we can report interface vs abstract method mismatch.
258 2001-10-03 Miguel de Icaza <miguel@ximian.com>
260 * report.cs: Make all of it static.
262 * rootcontext.cs: Drop object_type and value_type computations, as
263 we have those in the TypeManager anyways.
265 Drop report instance variable too, now it is a global.
267 * driver.cs: Use try/catch on command line handling.
269 Add --probe option to debug the error reporting system with a test
272 * report.cs: Add support for exiting program when a probe
273 condition is reached.
275 2001-10-03 Ravi Pratap <ravi@ximian.com>
277 * expression.cs (Binary::DoNumericPromotions): Fix the case when
278 we do a forcible conversion regardless of type, to check if
279 ForceConversion returns a null.
281 (Binary::error19): Use location to report error.
283 (Unary::error23): Use location here too.
285 * ../errors/cs0019.cs : Check in.
287 * ../errors/cs0023.cs : Check in.
289 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
290 case of a non-null MethodInfo object with a length of 0 !
292 (Binary::ResolveOperator): Flag error if overload resolution fails to find
293 an applicable member - according to the spec :-)
294 Also fix logic to find members in base types.
296 (Unary::ResolveOperator): Same here.
298 (Unary::report23): Change name to error23 and make first argument a TypeContainer
299 as I was getting thoroughly confused between this and error19 :-)
301 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
302 (::FindMostEncompassedType): Implement.
303 (::FindMostEncompassingType): Implement.
304 (::StandardConversionExists): Implement.
306 (UserImplicitCast): Re-vamp. We now need info about most specific
307 source and target types so that we can do the necessary conversions.
309 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
310 mathematical union with no duplicates.
312 2001-10-03 Miguel de Icaza <miguel@ximian.com>
314 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
315 in order from base classes to child classes, so that we can in
316 child classes look up in our parent for method names and
317 attributes (required for handling abstract, virtual, new, override
318 constructs: we need to instrospect our base class, and if we dont
319 populate the classes in order, the introspection might be
320 incorrect. For example, a method could query its parent before
321 the parent has any methods and would determine that the parent has
322 no abstract methods (while it could have had them)).
324 (RootContext::CreateType): Record the order in which we define the
327 2001-10-02 Miguel de Icaza <miguel@ximian.com>
329 * class.cs (TypeContainer::Populate): Also method definitions can
330 fail now, keep track of this.
332 (TypeContainer::FindMembers): Implement support for
333 DeclaredOnly/noDeclaredOnly flag.
335 (Constructor::Emit) Return the ConstructorBuilder.
337 (Method::Emit) Return the MethodBuilder.
338 Check for abstract or virtual methods to be public.
340 * rootcontext.cs (RootContext::CreateType): Register all the
341 abstract methods required for the class to be complete and the
342 interface methods that must be implemented.
344 * cs-parser.jay: Report error 501 (method requires body if it is
345 not marked abstract or extern).
347 * expression.cs (TypeOf::Emit): Implement.
349 * typemanager.cs: runtime_handle_type, new global type.
351 * class.cs (Property::Emit): Generate code for properties.
353 2001-10-02 Ravi Pratap <ravi@ximian.com>
355 * expression.cs (Unary::ResolveOperator): Find operators on base type
356 too - we now conform exactly to the spec.
358 (Binary::ResolveOperator): Same here.
360 * class.cs (Operator::Define): Fix minor quirk in the tests.
362 * ../errors/cs0215.cs : Added.
364 * ../errors/cs0556.cs : Added.
366 * ../errors/cs0555.cs : Added.
368 2001-10-01 Miguel de Icaza <miguel@ximian.com>
370 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
371 single integer which is really efficient
373 2001-10-01 Ravi Pratap <ravi@ximian.com>
375 * expression.cs (Expression::ImplicitUserConversion): Use location
376 even in the case when we are examining True operators.
378 * class.cs (Operator::Define): Perform extensive checks to conform
379 with the rules for operator overloading in the spec.
381 * expression.cs (Expression::ImplicitReferenceConversion): Implement
382 some of the other conversions mentioned in the spec.
384 * typemanager.cs (array_type): New static member for the System.Array built-in
387 (cloneable_interface): For System.ICloneable interface.
389 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
390 we start resolving the tree and populating types.
392 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
394 2001-10-01 Miguel de Icaza <miguel@ximian.com>
396 * expression.cs (Expression::ExprClassFromMemberInfo,
397 Expression::Literalize): Create literal expressions from
398 FieldInfos which are literals.
400 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
401 type casts, because they were wrong. The test suite in tests
404 (ImplicitNumericConversion): ushort to ulong requires a widening
407 Int32 constant to long requires widening cast as well.
409 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
410 for integers because the type on the stack is not i4.
412 2001-09-30 Miguel de Icaza <miguel@ximian.com>
414 * expression.cs (report118): require location argument.
416 * parameter.cs: Do not dereference potential null value.
418 * class.cs: Catch methods that lack the `new' keyword when
419 overriding a name. Report warnings when `new' is used without
420 anything being there to override.
422 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
424 * class.cs: Only add constructor to hashtable if it is non-null
425 (as now constructors can fail on define).
427 (TypeManager, Class, Struct): Take location arguments.
429 Catch field instance initialization in structs as errors.
431 accepting_filter: a new filter for FindMembers that is static so
432 that we dont create an instance per invocation.
434 (Constructor::Define): Catch errors where a struct constructor is
437 * cs-parser.jay: Pass location information for various new
440 * delegate.cs (Delegate): take a location argument.
442 * driver.cs: Do not call EmitCode if there were problesm in the
443 Definition of the types, as many Builders wont be there.
445 * decl.cs (Decl::Decl): Require a location argument.
447 * cs-tokenizer.cs: Handle properly hex constants that can not fit
448 into integers, and find the most appropiate integer for it.
450 * literal.cs: Implement ULongLiteral.
452 * rootcontext.cs: Provide better information about the location of
453 failure when CreateType fails.
455 2001-09-29 Miguel de Icaza <miguel@ximian.com>
457 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
460 * expression.cs (Binary::CheckShiftArguments): Add missing type
462 (Binary::ResolveOperator): Add type to the logical and and logical
463 or, Bitwise And/Or and Exclusive Or code paths, it was missing
466 (Binary::DoNumericPromotions): In the case where either argument
467 is ulong (and most signed types combined with ulong cause an
468 error) perform implicit integer constant conversions as well.
470 2001-09-28 Miguel de Icaza <miguel@ximian.com>
472 * expression.cs (UserImplicitCast): Method should always be
474 (Invocation::BetterConversion): Simplified test for IntLiteral.
476 (Expression::ImplicitNumericConversion): Split this routine out.
477 Put the code that performs implicit constant integer conversions
480 (Expression::Resolve): Become a wrapper around DoResolve so we can
481 check eclass and type being set after resolve.
483 (Invocation::Badness): Remove this dead function
485 (Binary::ResolveOperator): Do not compute the expensive argumnets
486 unless we have a union for it.
488 (Probe::Emit): Is needs to do an isinst and then
489 compare against null.
491 (::CanConvert): Added Location argument. If the Location argument
492 is null (Location.Null), then we do not report errors. This is
493 used by the `probe' mechanism of the Explicit conversion. We do
494 not want to generate an error for something that the user
495 explicitly requested to be casted. But the pipeline for an
496 explicit cast first tests for potential implicit casts.
498 So for now, if the Location is null, it means `Probe only' to
499 avoid adding another argument. Might have to revise this
502 (ClassCast): New class used to type cast objects into arbitrary
503 classes (used in Explicit Reference Conversions).
505 Implement `as' as well.
507 Reverted all the patches from Ravi below: they were broken:
509 * The use of `level' as a mechanism to stop recursive
510 invocations is wrong. That was there just to catch the
511 bug with a strack trace but not as a way of addressing
514 To fix the problem we have to *understand* what is going
515 on and the interactions and come up with a plan, not
516 just get things going.
518 * The use of the type conversion cache that I proposed
519 last night had an open topic: How does this work across
520 protection domains. A user defined conversion might not
521 be public in the location where we are applying the
522 conversion, a different conversion might be selected
523 (ie, private A->B (better) but public B->A (worse),
524 inside A, A->B applies, but outside it, B->A will
527 * On top of that (ie, even if the above is solved),
528 conversions in a cache need to be abstract. Ie, `To
529 convert from an Int to a Short use an OpcodeCast', not
530 `To convert from an Int to a Short use the OpcodeCast on
531 the variable 5' (which is what this patch was doing).
533 2001-09-28 Ravi Pratap <ravi@ximian.com>
535 * expression.cs (Invocation::ConversionExists): Re-write to use
538 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
539 cache all conversions done, not just user-defined ones.
541 (Invocation::BetterConversion): The real culprit. Use ConversionExists
542 to determine if a conversion exists instead of acutually trying to
543 perform the conversion. It's faster too.
545 (Expression::ConvertExplicit): Modify to use ConversionExists to check
546 and only then attempt the implicit conversion.
548 2001-09-28 Ravi Pratap <ravi@ximian.com>
550 * expression.cs (ConvertImplicit): Use a cache for conversions
551 already found. Check level of recursion and bail out if necessary.
553 2001-09-28 Miguel de Icaza <miguel@ximian.com>
555 * typemanager.cs (string_concat_string_string, string_concat_object_object):
556 Export standard methods that we expect for string operations.
558 * statement.cs (Block::UsageWarning): Track usage of variables and
559 report the errors for not used variables.
561 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
564 2001-09-27 Miguel de Icaza <miguel@ximian.com>
566 * codegen.cs: remove unnneded code
568 * expression.cs: Removed BuiltinTypeAccess class
570 Fix the order in which implicit conversions are
573 The previous fixed dropped support for boxed conversions (adding a
574 test to the test suite now)
576 (UserImplicitCast::CanConvert): Remove test for source being null,
577 that code is broken. We should not feed a null to begin with, if
578 we do, then we should track the bug where the problem originates
579 and not try to cover it up here.
581 Return a resolved expression of type UserImplicitCast on success
582 rather than true/false. Ravi: this is what I was talking about,
583 the pattern is to use a static method as a "constructor" for
586 Also, do not create arguments until the very last minute,
587 otherwise we always create the arguments even for lookups that
588 will never be performed.
590 (UserImplicitCast::Resolve): Eliminate, objects of type
591 UserImplicitCast are born in a fully resolved state.
593 * typemanager.cs (InitCoreTypes): Init also value_type
596 * expression.cs (Cast::Resolve): First resolve the child expression.
598 (LValue): Add new method AddressOf to be used by
601 Change the argument of Store to take an EmitContext instead of an
602 ILGenerator, because things like FieldExpr need to be able to call
603 their children expression to generate the instance code.
605 (Expression::Error, Expression::Warning): Sugar functions for
608 (Expression::MemberLookup): Accept a TypeContainer instead of a
609 Report as the first argument.
611 (Expression::ResolvePrimary): Killed. I still want to improve
612 this as currently the code is just not right.
614 (Expression::ResolveMemberAccess): Simplify, but it is still
617 (Unary::Resolve): Catch errors in AddressOf operators.
619 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
620 index to a byte for the short-version, or the compiler will choose
621 the wrong Emit call, which generates the wrong data.
623 (ParameterReference::Emit, ::Store): same.
625 (FieldExpr::AddressOf): Implement.
627 * typemanager.cs: TypeManager: made public variable instead of
630 * driver.cs: document --fatal.
632 * report.cs (ErrorMessage, WarningMessage): new names for the old
633 Error and Warning classes.
635 * cs-parser.jay (member_access): Turn built-in access to types
636 into a normal simplename
638 2001-09-27 Ravi Pratap <ravi@ximian.com>
640 * expression.cs (Invocation::BetterConversion): Fix to cope
641 with q being null, since this was introducing a bug.
643 * expression.cs (ConvertImplicit): Do built-in conversions first.
645 2001-09-27 Ravi Pratap <ravi@ximian.com>
647 * expression.cs (UserImplicitCast::Resolve): Fix bug.
649 2001-09-27 Ravi Pratap <ravi@ximian.com>
651 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
652 I had introduced long ago (what's new ?).
654 * expression.cs (UserImplicitCast::CanConvert): Static method to do
655 the work of all the checking.
656 (ConvertImplicit): Call CanConvert and only then create object if necessary.
657 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
659 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
660 that is the right way.
662 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
663 overloading resolution. Use everywhere instead of cutting and pasting code.
665 (Binary::ResolveOperator): Use MakeUnionSet.
667 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
668 we have to convert to bool types. Not complete yet.
670 2001-09-27 Miguel de Icaza <miguel@ximian.com>
672 * typemanager.cs (TypeManager::CSharpName): support ushort.
674 * expression.cs (Expression::TryImplicitIntConversion): Attempts
675 to provide an expression that performsn an implicit constant int
676 conversion (section 6.1.6).
677 (Expression::ConvertImplicitRequired): Reworked to include
678 implicit constant expression conversions.
680 (Expression::ConvertNumericExplicit): Finished.
682 (Invocation::Emit): If InstanceExpression is null, then it means
683 that we perform a call on this.
685 2001-09-26 Miguel de Icaza <miguel@ximian.com>
687 * expression.cs (Unary::Emit): Remove some dead code.
688 (Probe): Implement Resolve and Emit for `is'.
689 (Expression::ConvertImplicitRequired): Attempt to do constant
690 expression conversions here. Maybe should be moved to
691 ConvertImplicit, but I am not sure.
692 (Expression::ImplicitLongConstantConversionPossible,
693 Expression::ImplicitIntConstantConversionPossible): New functions
694 that tell whether is it possible to apply an implicit constant
695 expression conversion.
697 (ConvertNumericExplicit): Started work on explicit numeric
700 * cs-parser.jay: Update operator constants.
702 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
703 (Parameters::GetSignature): Hook up VerifyArgs here.
704 (Parameters::VerifyArgs): Verifies that no two arguments have the
707 * class.cs (Operator): Update the operator names to reflect the
708 ones that the spec expects (as we are just stringizing the
711 * expression.cs (Unary::ResolveOperator): Fix bug: Use
712 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
713 previous usage did only work for our methods.
714 (Expression::ConvertImplicit): Handle decimal implicit numeric
716 (Expression::InternalTypeConstructor): Used to invoke constructors
717 on internal types for default promotions.
719 (Unary::Emit): Implement special handling for the pre/post
720 increment/decrement for overloaded operators, as they need to have
721 the same semantics as the other operators.
723 (Binary::ResolveOperator): ditto.
724 (Invocation::ConversionExists): ditto.

744 expressions that can appear in statements, so that we can provide
745 an alternate path to generate expression that do not leave a value

789 (substract from zero from the non-constants).

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

924 expression for expressions which are just +expr.

957 * class.cs (Operator::Define): Fix a small bug for the case when we have

961 for the inbuilt operators. Only overloading works for now ;-)
963 2001-09-18 Miguel de Icaza <miguel@ximian.com>
965 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
966 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

979 (FieldExpr::Emit): Implement.
981 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
982 the last instruction contains a return opcode to avoid generating
983 the last `ret' instruction (this generates correct code, and it is
984 nice to pass the peverify output).
986 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
987 initializer for static and instance variables.
988 (Constructor::Emit): Allow initializer to be null in the case of
989 static constructors. Only emit initializer for instance

1045 (Expression::MemberLookup): Provide a version that allows to
1046 specify the MemberTypes and BindingFlags.

1049 so it was not fetching variable information from outer blocks.
1051 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
1052 Beforefieldinit as it was buggy.
1054 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
1057 * class.cs (Constructor::Emit): Only emit if block is not null.

1164 * driver.cs: Added --parse option that only parses its input files
1167 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
1168 incorrect. IsTopLevel is not used to tell whether an object is

1170 root_types). But to see if this is a top-level *class* (not
1171 necessarly our "toplevel" container).
1173 2001-09-14 Ravi Pratap <ravi@ximian.com>
1175 * enum.cs (Enum::Define): Modify to call the Lookup method on the

1191 * modifiers.cs (FieldAttr): Re-write.

1197 * modifiers.cs (MethodAttr): Re-write.
1198 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
1200 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent

1203 2001-09-13 Miguel de Icaza <miguel@ximian.com>
1205 * expression.cs (MemberLookup): Fruitless attempt to lookup
1206 constructors. Maybe I need to emit default constructors? That

1209 (Invocation::EmitArguments): new function, shared by the new

1233 (Populate): Only initialize method_builders_to_methods once.
1235 * expression.cs (PropertyExpr): Initialize type from the
1238 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

1243 (Binary::ResolveOperator): Set the return type to boolean for
1244 comparission operators
1246 * typemanager.cs: Remove debugging print code.
1248 (Invocation::Resolve): resolve type.
1250 * class.cs: Allocate a MemberInfo of the correct size, as the code
1251 elsewhere depends on the test to reflect the correct contents.
1253 (Method::) Keep track of parameters, due to System.Reflection holes
1255 (TypeContainer::Populate): Keep track of MethodBuilders to Method
1258 (TypeContainer::FindMembers): Use ArrayList and then copy an array
1259 of the exact size and return that.
1261 (Class::LookupMethodByBuilder): New function that maps
1262 MethodBuilders to its methods. Required to locate the information
1263 on methods because System.Reflection bit us again.
1265 * support.cs: New file, contains an interface ParameterData and
1266 two implementations: ReflectionParameters and InternalParameters
1267 used to access Parameter information. We will need to grow this
1270 * expression.cs (Invocation::GetParameterData): implement a cache
1271 and a wrapper around the ParameterData creation for methods.
1272 (Invocation::OverloadResolve): Use new code.
1274 2001-09-13 Ravi Pratap <ravi@ximian.com>

1328 2001-09-12 Ravi Pratap <ravi@ximian.com>
1330 * class.cs (TypeContainer::FindMembers): Method which does exactly
1331 what Type.FindMembers does, only we don't have to use reflection. No

1335 typecontainer objects as we need to get at them.
1336 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

1364 (Property::Define): Ditto.
1366 2001-09-10 Ravi Pratap <ravi@ximian.com>

1371 (Operator.OperatorMethodBuilder): New member to hold the method builder
1372 for the operator we are defining.

1378 addOn_ and removeOn_
1380 * genericparser.cs (GenericParser::error): Overloaded method to handle the case

1583 will is used during the tree rewriting as we resolve them during
1586 (Expression::MemberLookup): Implements the MemberLookup (7.3) from

1759 and re-write the code in the actions to extract the specific and
1760 general catch clauses by being a little smart ;-)
1762 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
1763 Hooray, try and catch statements parse fine !

1767 * statement.cs (Block::GetVariableType): Fix logic to extract the type
1768 string from the hashtable of variables.

1821 instead of ignoring the rank_specifiers.
1822 (expression_list): Implement to collect the expressions

1858 generation from working. Also add some temporary debugging
1861 2001-08-24 Miguel de Icaza <miguel@ximian.com>

1872 emission to keep a context. Most of the code generation will be

1897 function, and implements a cache that will be useful later when I
1898 do error checking and the semantic analysis on the methods is

1901 and made a method, optional argument tells whether this is a class
1902 or a structure to apply the `has-this' bit.

1938 track of static constructors; If none is used, turn on
1939 BeforeFieldInit in the TypeAttributes.

1942 for the cases where there are no arguments.
1944 (constructor_declarator): If there is no implicit `base' or

1947 * modifiers.cs (MethodAttr): New static function maps a set of
1948 modifiers flags into a MethodAttributes enum
1949 (FieldAttr): renamed from `Map'. So now we have FieldAttr,

1975 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):

1977 instead of doing this always.
1979 * parameter.cs: Handle refs and out parameters.
1981 * cs-parser.jay: Use an ArrayList to construct the arguments
1982 instead of the ParameterCollection, and then cast that to a
1985 * parameter.cs: Drop the use of ParameterCollection and use
1986 instead arrays of Parameters.

2007 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
2008 this System.Reflection code is. Kudos to Microsoft
2010 * typemanager.cs: Implement a type cache and avoid loading all
2011 types at boot time. Wrap in LookupType the internals. This made
2012 the compiler so much faster. Wow. I rule!
2014 * driver.cs: Make sure we always load mscorlib first (for
2015 debugging purposes, nothing really important).
2017 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
2018 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
2020 * rootcontext.cs: Lookup types on their namespace; Lookup types
2021 on namespaces that have been imported using the `using' keyword.
2023 * class.cs (TypeContainer::TypeAttr): Virtualize.
2024 (Class::TypeAttr): Return attributes suitable for this bad boy.
2025 (Struct::TypeAttr): ditto.
2026 Handle nested classes.
2027 (TypeContainer::) Remove all the type visiting code, it is now
2028 replaced with the rootcontext.cs code
2030 * rootcontext.cs (GetClassBases): Added support for structs.
2032 2001-08-06 Miguel de Icaza <miguel@ximian.com>
2034 * interface.cs, statement.cs, class.cs, parameter.cs,
2035 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
2036 Drop use of TypeRefs, and use strings instead.
2038 2001-08-04 Miguel de Icaza <miguel@ximian.com>
2042 * class.cs (Struct::Struct): set the SEALED flags after
2043 checking the modifiers.
2044 (TypeContainer::TypeAttr): new property, returns the
2045 TypeAttributes for a class.
2047 * cs-parser.jay (type_list): Oops, list production was creating a
2048 new list of base types.
2050 * rootcontext.cs (StdLib): New property.
2051 (GetInterfaceTypeByName): returns an interface by type name, and
2052 encapsulates error handling here.
2053 (GetInterfaces): simplified.
2054 (ResolveTree): Encapsulated all the tree resolution here.
2055 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
2058 * driver.cs: Add support for --nostdlib, to avoid loading the
2060 (Main): Do not put tree resolution here.
2062 * rootcontext.cs: Beginning of the class resolution.
2064 2001-08-03 Miguel de Icaza <miguel@ximian.com>
2066 * rootcontext.cs: Provide better error reporting.
2068 * cs-parser.jay (interface_base): set our $$ to be interfaces.
2070 * rootcontext.cs (CreateInterface): Handle the case where there
2071 are no parent interfaces.
2073 (CloseTypes): Routine to flush types at the end.
2074 (CreateInterface): Track types.
2075 (GetInterfaces): Returns an array of Types from the list of
2078 * typemanager.c (AddUserType): Mechanism to track user types (puts
2079 the type on the global type hash, and allows us to close it at the
2082 2001-08-02 Miguel de Icaza <miguel@ximian.com>
2084 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
2085 RecordInterface instead.
2087 * cs-parser.jay: Updated to reflect changes above.
2089 * decl.cs (Definition): Keep track of the TypeBuilder type that
2090 represents this type here. Not sure we will use it in the long
2091 run, but wont hurt for now.
2093 * driver.cs: Smaller changes to accomodate the new code.
2095 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
2098 * rootcontext.cs (CreateInterface): New method, used to create
2099 the System.TypeBuilder type for interfaces.
2100 (ResolveInterfaces): new entry point to resolve the interface
2102 (CodeGen): Property, used to keep track of the code generator.
2104 2001-07-26 Miguel de Icaza <miguel@ximian.com>
2106 * cs-parser.jay: Add a second production for delegate_declaration
2109 (enum_body): Put an opt_comma here instead of putting it on
2110 enum_body or enum_member_declarations so we can handle trailing
2111 commas on enumeration members. Gets rid of a shift/reduce.
2113 (type_list): Need a COMMA in the middle.
2115 (indexer_declaration): Tell tokenizer to recognize get/set
2117 * Remove old targets.
2119 * Re-add the parser target.
2121 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2123 * cs-parser.jay: Add precendence rules for a number of operators
2124 ot reduce the number of shift/reduce conflicts in the grammar.
2126 2001-07-17 Miguel de Icaza <miguel@ximian.com>
2128 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
2131 Get rid of old crufty code.
2133 * rootcontext.cs: Use this to keep track of the parsed
2134 representation and the defined types available to the program.
2136 * gen-treedump.cs: adjust for new convention.
2138 * type.cs: Split out the type manager, and the assembly builder
2141 * typemanager.cs: the type manager will live here now.
2143 * cil-codegen.cs: And the code generator here.
2145 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
2147 * makefile: Fixed up for easy making.
2149 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2151 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
2154 (unary_expression): Expand pre_increment_expression and
2155 post_decrement_expression to reduce a shift/reduce.
2157 2001-07-11 Simon Cozens
2159 * cs-tokenizer.cs: Hex numbers should begin with a 0.
2161 Improve allow_keyword_as_indent name.
2163 2001-06-19 Miguel de Icaza <miguel@ximian.com>
2165 * Adjustments for Beta2.
2167 2001-06-13 Miguel de Icaza <miguel@ximian.com>
2169 * decl.cs: Added `Define' abstract method.
2170 (InTransit): new property, used to catch recursive definitions.
2172 * interface.cs: Implement `Define'.
2174 * modifiers.cs: Map Modifiers.constants to
2175 System.Reflection.TypeAttribute flags.
2177 * class.cs: Keep track of types and user-defined types.
2178 (BuilderInit): New method for creating an assembly
2179 (ResolveType): New function to launch the resolution process, only
2180 used by interfaces for now.
2182 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
2183 that are inserted into the name space.
2185 2001-06-08 Miguel de Icaza <miguel@ximian.com>
2187 * ARGH. I have screwed up my tree so many times due to the use of
2188 rsync rather than using CVS. Going to fix this at once.
2190 * driver.cs: Objetify driver. Load assemblies, use assemblies to
2193 2001-06-07 Miguel de Icaza <miguel@ximian.com>
2195 * Experiment successful: Use System.Type rather that our own
2198 2001-05-25 Miguel de Icaza <miguel@ximian.com>
2200 * cs-parser.jay: Removed nsAliases from here.
2202 Use new namespaces, handle `using XXX;'
2204 * namespace.cs: Reimplemented namespace handling, use a recursive
2205 definition of the class. Now we can keep track of using clauses
2206 and catch invalid using clauses.
2208 2001-05-24 Miguel de Icaza <miguel@ximian.com>
2210 * gen-treedump.cs: Adapted for all the renaming.
2212 * expression.cs (Expression): this class now has a Type property
2213 which returns an expression Type.
2215 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
2216 `Type', as this has a different meaning now in the base
2218 2001-05-22 Miguel de Icaza <miguel@ximian.com>
2220 * interface.cs, class.cs: Removed from all the sources the
2221 references to signature computation, as we can not do method
2222 signature computation during the parsing time, as we are not
2223 trying to solve at that point distinguishing:
2227 void a (NS.Blah x) {}
2230 Which depending on the context might be valid or not, as we do not
2231 know if Blah is the same thing as NS.Blah at that point.
2233 * Redid everything so the code uses TypeRefs now instead of
2234 Types. TypeRefs are just temporary type placeholders, that need
2235 to be resolved. They initially have a pointer to a string and the
2236 current scope in which they are used. This is used later by the
2237 compiler to resolve the reference to an actual Type.
2239 * DeclSpace is no longer a CIR.Type, and neither are
2240 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
2241 are all DeclSpaces, but no Types.
2243 * type.cs (TypeRefManager): This implements the TypeRef manager,
2244 which keeps track of all the types that need to be resolved after
2245 the parsing has finished.
2247 2001-05-13 Miguel de Icaza <miguel@ximian.com>
2249 * ARGH. We are going to have to store `foreach' as a class rather
2250 than resolving it, as we need to verify error 1579 after name
2251 resolution. *OR* we could keep a flag that says `This request to
2252 IEnumerator comes from a foreach statement' which we can then use
2253 to generate the error.
2255 2001-05-10 Miguel de Icaza <miguel@ximian.com>
2257 * class.cs (TypeContainer.AddMethod): we now add methods to the
2258 MethodGroup instead of the method hashtable.
2260 * expression.cs: Add MethodGroup abstraction, which gets us one
2261 step closer to the specification in the way we handle method
2264 * cs-parser.jay (primary_expression): qualified_identifier now
2265 tried to match up an identifier to a local variable reference or
2266 to a parameter reference.
2268 current_local_parameters is now a parser global variable that
2269 points to the current parameters for the block, used during name
2272 (property_declaration): Now creates an implicit `value' argument to
2275 2001-05-09 Miguel de Icaza <miguel@ximian.com>
2277 * parameter.cs: Do not use `param' arguments as part of the
2278 signature, per the spec.
2280 2001-05-08 Miguel de Icaza <miguel@ximian.com>
2282 * decl.cs: Base class for classes, structs and interfaces. This
2283 is the "Declaration Space"
2285 * cs-parser.jay: Use CheckDef for checking declaration errors
2286 instead of having one on each function.
2288 * class.cs: Factor out some code for handling error handling in
2289 accordance to the "Declarations" section in the "Basic Concepts"
2290 chapter in the ECMA C# spec.
2292 * interface.cs: Make all interface member classes derive from
2293 InterfaceMemberBase.
2295 2001-05-07 Miguel de Icaza <miguel@ximian.com>
2297 * Many things: all interfaces are parsed and generated in
2298 gen-treedump. Support for member variables, constructors,
2299 destructors, properties, constants is there.
2301 Beginning of the IL backend, but very little done, just there for
2304 2001-04-29 Miguel de Icaza <miguel@ximian.com>
2306 * cs-parser.jay: Fix labeled statement.
2308 * cs-tokenizer.cs (escape): Escape " and ' always.
2309 ref_line, ref_name: keep track of the line/filename as instructed
2310 by #line by the compiler.
2313 2001-04-27 Miguel de Icaza <miguel@ximian.com>
2315 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
2316 to match the values in System.CodeDOM.
2318 Divid renamed to Divide.
2320 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
2322 (Statements.set): remove.
2324 * System.CodeDOM/CodeCatchClause.cs: always have a valid
2327 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
2328 falseStatements always have valid values.
2330 * cs-parser.jay: Use System.CodeDOM now.
