1 2001-10-03 Ravi Pratap <ravi@ximian.com>
3 * expression.cs (Binary::DoNumericPromotions): Fix the case when
4 we do a forcible conversion regardless of type, to check if
5 ForceConversion returns a null.
7 (Binary::error19): Use location to report error.
9 (Unary::error23): Use location here too.
11 * ../errors/cs0019.cs : Check in.
13 * ../errors/cs0023.cs : Check in.
15 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
16 case of a non-null MethodInfo object with a length of 0 !
18 (Binary::ResolveOperator): Flag error if overload resolution fails to find
19 an applicable member - according to the spec :-)
20 Also fix logic to find members in base types.
22 (Unary::ResolveOperator): Same here.
24 (Unary::report23): Change name to error23 and make first argument a TypeContainer
25 as I was getting thoroughly confused between this and error19 :-)
27 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
28 (::FindMostEncompassedType): Implement.
29 (::FindMostEncompassingType): Implement.
30 (::StandardConversionExists): Implement.
32 (UserImplicitCast): Re-vamp. We now need info about most specific
33 source and target types so that we can do the necessary conversions.
35 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
36 mathematical union with no duplicates.
38 2001-10-03 Miguel de Icaza <miguel@ximian.com>
40 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
41 in order from base classes to child classes, so that we can in
42 child classes look up in our parent for method names and
43 attributes (required for handling abstract, virtual, new, override
44 constructs: we need to instrospect our base class, and if we dont
45 populate the classes in order, the introspection might be
46 incorrect. For example, a method could query its parent before
47 the parent has any methods and would determine that the parent has
48 no abstract methods (while it could have had them)).
50 (RootContext::CreateType): Record the order in which we define the
53 2001-10-02 Miguel de Icaza <miguel@ximian.com>
55 * class.cs (TypeContainer::Populate): Also method definitions can
56 fail now, keep track of this.
58 (TypeContainer::FindMembers): Implement support for
59 DeclaredOnly/noDeclaredOnly flag.
61 (Constructor::Emit) Return the ConstructorBuilder.
63 (Method::Emit) Return the MethodBuilder.
64 Check for abstract or virtual methods to be public.
66 * rootcontext.cs (RootContext::CreateType): Register all the
67 abstract methods required for the class to be complete and the
68 interface methods that must be implemented.
70 * cs-parser.jay: Report error 501 (method requires body if it is
71 not marked abstract or extern).
73 * expression.cs (TypeOf::Emit): Implement.
75 * typemanager.cs: runtime_handle_type, new global type.
77 * class.cs (Property::Emit): Generate code for properties.
79 2001-10-02 Ravi Pratap <ravi@ximian.com>
81 * expression.cs (Unary::ResolveOperator): Find operators on base type
82 too - we now conform exactly to the spec.
84 (Binary::ResolveOperator): Same here.
86 * class.cs (Operator::Define): Fix minor quirk in the tests.
88 * ../errors/cs0215.cs : Added.
90 * ../errors/cs0556.cs : Added.
92 * ../errors/cs0555.cs : Added.
94 2001-10-01 Miguel de Icaza <miguel@ximian.com>
96 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
97 single integer which is really efficient
99 2001-10-01 Ravi Pratap <ravi@ximian.com>
101 * expression.cs (Expression::ImplicitUserConversion): Use location
102 even in the case when we are examining True operators.
104 * class.cs (Operator::Define): Perform extensive checks to conform
105 with the rules for operator overloading in the spec.
107 * expression.cs (Expression::ImplicitReferenceConversion): Implement
108 some of the other conversions mentioned in the spec.
110 * typemanager.cs (array_type): New static member for the System.Array built-in
113 (cloneable_interface): For System.ICloneable interface.
115 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
116 we start resolving the tree and populating types.
118 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
120 2001-10-01 Miguel de Icaza <miguel@ximian.com>
122 * expression.cs (Expression::ExprClassFromMemberInfo,
123 Expression::Literalize): Create literal expressions from
124 FieldInfos which are literals.
126 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
127 type casts, because they were wrong. The test suite in tests
130 (ImplicitNumericConversion): ushort to ulong requires a widening
133 Int32 constant to long requires widening cast as well.
135 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
136 for integers because the type on the stack is not i4.
138 2001-09-30 Miguel de Icaza <miguel@ximian.com>
140 * expression.cs (report118): require location argument.
142 * parameter.cs: Do not dereference potential null value.
144 * class.cs: Catch methods that lack the `new' keyword when
145 overriding a name. Report warnings when `new' is used without
146 anything being there to override.
148 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
150 * class.cs: Only add constructor to hashtable if it is non-null
151 (as now constructors can fail on define).
153 (TypeManager, Class, Struct): Take location arguments.
155 Catch field instance initialization in structs as errors.
157 accepting_filter: a new filter for FindMembers that is static so
158 that we dont create an instance per invocation.
160 (Constructor::Define): Catch errors where a struct constructor is
163 * cs-parser.jay: Pass location information for various new
166 * delegate.cs (Delegate): take a location argument.
168 * driver.cs: Do not call EmitCode if there were problesm in the
169 Definition of the types, as many Builders wont be there.
171 * decl.cs (Decl::Decl): Require a location argument.
173 * cs-tokenizer.cs: Handle properly hex constants that can not fit
174 into integers, and find the most appropiate integer for it.
176 * literal.cs: Implement ULongLiteral.
178 * rootcontext.cs: Provide better information about the location of
179 failure when CreateType fails.
181 2001-09-29 Miguel de Icaza <miguel@ximian.com>
183 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
186 * expression.cs (Binary::CheckShiftArguments): Add missing type
188 (Binary::ResolveOperator): Add type to the logical and and logical
189 or, Bitwise And/Or and Exclusive Or code paths, it was missing
192 (Binary::DoNumericPromotions): In the case where either argument
193 is ulong (and most signed types combined with ulong cause an
194 error) perform implicit integer constant conversions as well.
196 2001-09-28 Miguel de Icaza <miguel@ximian.com>
198 * expression.cs (UserImplicitCast): Method should always be
200 (Invocation::BetterConversion): Simplified test for IntLiteral.
202 (Expression::ImplicitNumericConversion): Split this routine out.
203 Put the code that performs implicit constant integer conversions
206 (Expression::Resolve): Become a wrapper around DoResolve so we can
207 check eclass and type being set after resolve.
209 (Invocation::Badness): Remove this dead function
211 (Binary::ResolveOperator): Do not compute the expensive argumnets
212 unless we have a union for it.
214 (Probe::Emit): Is needs to do an isinst and then
215 compare against null.
217 (::CanConvert): Added Location argument. If the Location argument
218 is null (Location.Null), then we do not report errors. This is
219 used by the `probe' mechanism of the Explicit conversion. We do
220 not want to generate an error for something that the user
221 explicitly requested to be casted. But the pipeline for an
222 explicit cast first tests for potential implicit casts.
224 So for now, if the Location is null, it means `Probe only' to
225 avoid adding another argument. Might have to revise this
228 (ClassCast): New class used to type cast objects into arbitrary
229 classes (used in Explicit Reference Conversions).
231 Implement `as' as well.
233 Reverted all the patches from Ravi below: they were broken:
235 * The use of `level' as a mechanism to stop recursive
236 invocations is wrong. That was there just to catch the
237 bug with a strack trace but not as a way of addressing
240 To fix the problem we have to *understand* what is going
241 on and the interactions and come up with a plan, not
242 just get things going.
244 * The use of the type conversion cache that I proposed
245 last night had an open topic: How does this work across
246 protection domains. A user defined conversion might not
247 be public in the location where we are applying the
248 conversion, a different conversion might be selected
249 (ie, private A->B (better) but public B->A (worse),
250 inside A, A->B applies, but outside it, B->A will
253 * On top of that (ie, even if the above is solved),
254 conversions in a cache need to be abstract. Ie, `To
255 convert from an Int to a Short use an OpcodeCast', not
256 `To convert from an Int to a Short use the OpcodeCast on
257 the variable 5' (which is what this patch was doing).
259 2001-09-28 Ravi Pratap <ravi@ximian.com>
261 * expression.cs (Invocation::ConversionExists): Re-write to use
264 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
265 cache all conversions done, not just user-defined ones.
267 (Invocation::BetterConversion): The real culprit. Use ConversionExists
268 to determine if a conversion exists instead of acutually trying to
269 perform the conversion. It's faster too.
271 (Expression::ConvertExplicit): Modify to use ConversionExists to check
272 and only then attempt the implicit conversion.
274 2001-09-28 Ravi Pratap <ravi@ximian.com>
276 * expression.cs (ConvertImplicit): Use a cache for conversions
277 already found. Check level of recursion and bail out if necessary.
279 2001-09-28 Miguel de Icaza <miguel@ximian.com>
281 * typemanager.cs (string_concat_string_string, string_concat_object_object):
282 Export standard methods that we expect for string operations.
284 * statement.cs (Block::UsageWarning): Track usage of variables and
285 report the errors for not used variables.
287 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
290 2001-09-27 Miguel de Icaza <miguel@ximian.com>
292 * codegen.cs: remove unnneded code
294 * expression.cs: Removed BuiltinTypeAccess class
296 Fix the order in which implicit conversions are
299 The previous fixed dropped support for boxed conversions (adding a
300 test to the test suite now)
302 (UserImplicitCast::CanConvert): Remove test for source being null,
303 that code is broken. We should not feed a null to begin with, if
304 we do, then we should track the bug where the problem originates
305 and not try to cover it up here.
307 Return a resolved expression of type UserImplicitCast on success
308 rather than true/false. Ravi: this is what I was talking about,
309 the pattern is to use a static method as a "constructor" for
312 Also, do not create arguments until the very last minute,
313 otherwise we always create the arguments even for lookups that
314 will never be performed.
316 (UserImplicitCast::Resolve): Eliminate, objects of type
317 UserImplicitCast are born in a fully resolved state.
319 * typemanager.cs (InitCoreTypes): Init also value_type
322 * expression.cs (Cast::Resolve): First resolve the child expression.
324 (LValue): Add new method AddressOf to be used by
327 Change the argument of Store to take an EmitContext instead of an
328 ILGenerator, because things like FieldExpr need to be able to call
329 their children expression to generate the instance code.
331 (Expression::Error, Expression::Warning): Sugar functions for
334 (Expression::MemberLookup): Accept a TypeContainer instead of a
335 Report as the first argument.
337 (Expression::ResolvePrimary): Killed. I still want to improve
338 this as currently the code is just not right.
340 (Expression::ResolveMemberAccess): Simplify, but it is still
343 (Unary::Resolve): Catch errors in AddressOf operators.
345 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
346 index to a byte for the short-version, or the compiler will choose
347 the wrong Emit call, which generates the wrong data.
349 (ParameterReference::Emit, ::Store): same.
351 (FieldExpr::AddressOf): Implement.
353 * typemanager.cs: TypeManager: made public variable instead of
356 * driver.cs: document --fatal.
358 * report.cs (ErrorMessage, WarningMessage): new names for the old
359 Error and Warning classes.
361 * cs-parser.jay (member_access): Turn built-in access to types
362 into a normal simplename
364 2001-09-27 Ravi Pratap <ravi@ximian.com>

377 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
378 I had introduced long ago (what's new ?).
380 * expression.cs (UserImplicitCast::CanConvert): Static method to do
381 the work of all the checking.
382 (ConvertImplicit): Call CanConvert and only then create object if necessary.
383 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
385 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
386 that is the right way.
388 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
389 overloading resolution. Use everywhere instead of cutting and pasting code.
391 (Binary::ResolveOperator): Use MakeUnionSet.
393 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
394 we have to convert to bool types. Not complete yet.
396 2001-09-27 Miguel de Icaza <miguel@ximian.com>
398 * typemanager.cs (TypeManager::CSharpName): support ushort.
400 * expression.cs (Expression::TryImplicitIntConversion): Attempts
401 to provide an expression that performsn an implicit constant int
402 conversion (section 6.1.6).
403 (Expression::ConvertImplicitRequired): Reworked to include
404 implicit constant expression conversions.
406 (Expression::ConvertNumericExplicit): Finished.
408 (Invocation::Emit): If InstanceExpression is null, then it means
409 that we perform a call on this.
411 2001-09-26 Miguel de Icaza <miguel@ximian.com>
413 * expression.cs (Unary::Emit): Remove some dead code.
414 (Probe): Implement Resolve and Emit for `is'.
415 (Expression::ConvertImplicitRequired): Attempt to do constant
416 expression conversions here. Maybe should be moved to
417 ConvertImplicit, but I am not sure.
418 (Expression::ImplicitLongConstantConversionPossible,
419 Expression::ImplicitIntConstantConversionPossible): New functions
420 that tell whether is it possible to apply an implicit constant
421 expression conversion.
423 (ConvertNumericExplicit): Started work on explicit numeric
426 * cs-parser.jay: Update operator constants.
428 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
429 (Parameters::GetSignature): Hook up VerifyArgs here.
430 (Parameters::VerifyArgs): Verifies that no two arguments have the
433 * class.cs (Operator): Update the operator names to reflect the
434 ones that the spec expects (as we are just stringizing the
437 * expression.cs (Unary::ResolveOperator): Fix bug: Use
438 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
439 previous usage did only work for our methods.
440 (Expression::ConvertImplicit): Handle decimal implicit numeric
442 (Expression::InternalTypeConstructor): Used to invoke constructors
443 on internal types for default promotions.
445 (Unary::Emit): Implement special handling for the pre/post
446 increment/decrement for overloaded operators, as they need to have
447 the same semantics as the other operators.
449 (Binary::ResolveOperator): ditto.
450 (Invocation::ConversionExists): ditto.
451 (UserImplicitCast::Resolve): ditto.
453 2001-09-26 Ravi Pratap <ravi@ximian.com>

467 * assign.cs (Assign): Make it inherit from ExpressionStatement.
469 * expression.cs (ExpressionStatement): New base class used for
470 expressions that can appear in statements, so that we can provide
471 an alternate path to generate expression that do not leave a value
474 (Expression::Emit, and all the derivatives): We no longer return
475 whether a value is left on the stack or not. Every expression
476 after being emitted leaves a single value on the stack.
478 * codegen.cs (EmitContext::EmitStatementExpression): Use the
479 facilties of ExpressionStatement if possible.
481 * cs-parser.jay: Update statement_expression.

506 * assign.cs: track location.
507 (Resolve): Use implicit conversions on assignment.
509 * literal.cs: Oops. Not good, Emit of short access values should
510 pass (Bytes) or the wrong argument will be selected.
512 * expression.cs (Unary::Emit): Emit code for -expr.
514 (Unary::ResolveOperator): Handle `Substract' for non-constants
515 (substract from zero from the non-constants).

519 error if no implicit conversion exists.
521 (Invocation::OverloadResolve): Store the converted implicit
522 expressions if we make them

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

572 * typemanager.cs: declare and load enum_type, delegate_type and
575 * expression.cs (Expression::Emit): Now emit returns a value that
576 tells whether a value is left on the stack or not. This strategy
577 might be reveted tomorrow with a mechanism that would address
578 multiple assignments.
579 (Expression::report118): Utility routine to report mismatches on
582 (Unary::Report23): Report impossible type/operator combination
585 (Unary::IsIncrementableNumber): Whether the type can be
586 incremented or decremented with add.
587 (Unary::ResolveOperator): Also allow enumerations to be bitwise
589 (Unary::ResolveOperator): Implement ++, !, ~, ++ and --.
591 (Invocation::Emit): Deal with new Emit convetion.
593 * All Expression derivatives: Updated their Emit method to return
594 whether they leave values on the stack or not.
596 * codegen.cs (CodeGen::EmitStatement): Pop values left on the
597 stack for expressions that are statements.
599 2001-09-20 Miguel de Icaza <miguel@ximian.com>
601 * expression.cs (LValue): New interface. Must be implemented by
603 (LocalVariableReference, ParameterReference, FieldExpr): Implement
606 * assign.cs (Assign::Emit, Assign::Resolve): Use new LValue

626 otherwise nested blocks end up with the same index.
628 * codegen.cs (CodeGen::EmitTopBlock): Pass initial sequence
630 * expression.cs: Instead of having FIXMEs in the Resolve
631 functions, throw exceptions so it is obvious that we are facing a
634 * cs-parser.jay (invocation_expression): Pass Location information.
636 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
637 Use a basename for those routines because .NET does not like paths

649 * expression.cs (Unary::ResolveOperator): return the child
650 expression for expressions which are just +expr.

675 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
676 operators are found instead of making noise ;-)
677 (Unary::ResolveOperator): New method to do precisely the same thing which
678 Binary::ResolveOperator does for Binary expressions.
679 (Unary.method, .Arguments): Add.
680 (Unary::OperName): Implement.
681 (Unary::ForceConversion): Copy and Paste !
683 * class.cs (Operator::Define): Fix a small bug for the case when we have
686 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
687 for the inbuilt operators. Only overloading works for now ;-)
689 2001-09-18 Miguel de Icaza <miguel@ximian.com>

705 (FieldExpr::Emit): Implement.
707 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
708 the last instruction contains a return opcode to avoid generating
709 the last `ret' instruction (this generates correct code, and it is
710 nice to pass the peverify output).
712 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
713 initializer for static and instance variables.
714 (Constructor::Emit): Allow initializer to be null in the case of
715 static constructors. Only emit initializer for instance
718 (TypeContainer::FindMembers): Return a null array if there are no
721 Also fix the code for the MemberTypes.Method branch, as it was not
722 scanning that for operators (or tried to access null variables before).
724 * assign.cs (Assign::Emit): Handle instance and static fields.
728 * driver.cs: Stop compilation if there are parse errors.
730 * cs-parser.jay (constructor_declaration): Provide default base
731 initializer for non-static constructors.

733 initializers if none was specified.
734 Catch the fact that constructors should not have parameters.
736 * class.cs: Do not emit parent class initializers for static
737 constructors, that should be flagged as an error.

766 2001-09-17 Miguel de Icaza <miguel@ximian.com>
768 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
771 (Expression::MemberLookup): Provide a version that allows to
772 specify the MemberTypes and BindingFlags.
774 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
775 so it was not fetching variable information from outer blocks.

784 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
785 deal with this by semantically definining it as if the user had
788 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
789 constructors as we now "emit" them at a higher level.
791 (TypeContainer::DefineDefaultConstructor): Used to define the
792 default constructors if none was provided.

809 2001-09-17 Ravi Pratap <ravi@ximian.com>
811 * rootcontext.cs (IsNameSpace): Compare against null.

827 (TypeContainer::Emit): Emit the operators we have too.
829 * expression.cs (Binary::Emit): Update to emit the appropriate code for
830 the case when we have a user-defined operator.
832 2001-09-17 Miguel de Icaza <miguel@ximian.com>
834 * rootcontext.cs: Fix bug: tree.Namespaces might be null.
836 2001-09-16 Ravi Pratap <ravi@ximian.com>
838 * class.cs (EmitStaticFieldInitializers, EmitFieldInitializers): Make public.

859 * cs-parser.jay (namespace_declaration): Call RecordNamespace to
862 * rootcontext.cs (IsNamespace): Fixed it :-)
864 2001-09-14 Miguel de Icaza <miguel@ximian.com>

877 * modifiers.cs: Do not use `parent', instead use the real type
878 container to evaluate permission settings.
880 * class.cs: Put Ravi's patch back in. He is right, and we will
881 have to cope with the
883 2001-09-14 Ravi Pratap <ravi@ximian.com>
885 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
886 FamORAssem, not FamANDAssem.

890 * driver.cs: Added --parse option that only parses its input files
893 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
894 incorrect. IsTopLevel is not used to tell whether an object is
895 root_types or not (that can be achieved by testing this ==
896 root_types). But to see if this is a top-level *class* (not
897 necessarly our "toplevel" container).
899 2001-09-14 Ravi Pratap <ravi@ximian.com>
901 * enum.cs (Enum::Define): Modify to call the Lookup method on the
902 parent instead of a direct call to GetType.
904 2001-09-14 Ravi Pratap <ravi@ximian.com>
906 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
907 Modifiers.TypeAttr. This should just be a call to that method.
909 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
910 object so that we can determine if we are top-level or not.
912 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the

920 (TypeContainer::HaveStaticConstructor): New property to provide access
921 to precisely that info.
923 * modifiers.cs (MethodAttr): Re-write.
924 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
926 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
927 of top-level types as claimed.
929 2001-09-13 Miguel de Icaza <miguel@ximian.com>
931 * expression.cs (MemberLookup): Fruitless attempt to lookup
932 constructors. Maybe I need to emit default constructors? That
933 might be it (currently .NET emits this for me automatically).
934 (Invocation::OverloadResolve): Cope with Arguments == null.
935 (Invocation::EmitArguments): new function, shared by the new

949 SimpleLookup): Auxiliary routines to help parse a qualifier
952 Update qualifier_identifier rule.
954 * codegen.cs: Removed debugging messages.

957 objects that we might have around.
959 (Populate): Only initialize method_builders_to_methods once.
961 * expression.cs (PropertyExpr): Initialize type from the
964 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
965 Resolve pattern. Attempt to implicitly convert value to boolean.
968 * expression.cs: Set the type for the int32/int32 argument case.
969 (Binary::ResolveOperator): Set the return type to boolean for
970 comparission operators
972 * typemanager.cs: Remove debugging print code.
974 (Invocation::Resolve): resolve type.
976 * class.cs: Allocate a MemberInfo of the correct size, as the code
977 elsewhere depends on the test to reflect the correct contents.
979 (Method::) Keep track of parameters, due to System.Reflection holes
981 (TypeContainer::Populate): Keep track of MethodBuilders to Method
984 (TypeContainer::FindMembers): Use ArrayList and then copy an array
985 of the exact size and return that.
987 (Class::LookupMethodByBuilder): New function that maps
988 MethodBuilders to its methods. Required to locate the information
989 on methods because System.Reflection bit us again.
991 * support.cs: New file, contains an interface ParameterData and
992 two implementations: ReflectionParameters and InternalParameters
993 used to access Parameter information. We will need to grow this
996 * expression.cs (Invocation::GetParameterData): implement a cache
997 and a wrapper around the ParameterData creation for methods.
998 (Invocation::OverloadResolve): Use new code.
1000 2001-09-13 Ravi Pratap <ravi@ximian.com>

1011 initialized with the full type once it is resolved.
1013 2001-09-12 Miguel de Icaza <miguel@ximian.com>
1015 * parameter.cs (GetParameterInfo): Use a type cache to compute
1016 things only once, and to reuse this information

1054 2001-09-12 Ravi Pratap <ravi@ximian.com>
1056 * class.cs (TypeContainer::FindMembers): Method which does exactly
1057 what Type.FindMembers does, only we don't have to use reflection. No
1060 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
1061 typecontainer objects as we need to get at them.
1062 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

1065 typecontainer object.

1103 * class.cs (Event::Define): Make the prefixes of the accessor methods
1104 addOn_ and removeOn_
1106 * genericparser.cs (GenericParser::error): Overloaded method to handle the case

1108 error reporting should be done through the Report object.
1110 * class.cs (TypeContainer.Indexers): New property to access the list of indexers.
1111 (Populate): Iterate thru the indexers we have and define them too.

1309 will is used during the tree rewriting as we resolve them during

1364 (fixed_parameter): Ditto.
1365 (parameter_array): Ditto.
1366 (property_declaration): Ditto.
1368 * constant.cs (Constant::Constant): Update constructor similarly.

1376 (TypeContainer.delegates): New member to hold list of delegates.
1378 * cs-parser.jay (delegate_declaration): Implement the action correctly
1379 this time as I seem to be on crack ;-)
1381 2001-09-02 Miguel de Icaza <miguel@ximian.com>
1383 * rootcontext.cs (RootContext::IsNamespace): new function, used to
1384 tell whether an identifier represents a namespace.

1409 * cs-parser.jay : Clean out commented cruft.
1410 (dimension_separators, dimension_separator): Comment out. Ostensibly not
1411 used anywhere - non-reducing rule.
1412 (namespace_declarations): Non-reducing rule - comment out.
1414 * enum.cs (Enum::AddEnum): Rename to AddEnumMember as I was getting confused
1415 with TypeContainer::AddEnum.

1418 (Delegate): Class for declaring delegates.
1420 * makefile : Update.

1427 (Event.EventBuilder): New member.
1429 * class.cs (TypeContainer::Populate): Update to define all enums and events
1431 (Events): New property for the events arraylist we hold. Shouldn't we move to using
1432 readonly fields for all these cases ?
1434 2001-08-31 Ravi Pratap <ravi@che.iitm.ac.in>
1436 * class.cs (Property): Revamp to use the convention of making fields readonly.
1437 Accordingly modify code elsewhere.
1439 * class.cs : Apply patch from Mr. Mandar <go_mono@hotmail.com> for implementing
1440 the Define method of the Property class.
1442 * class.cs : Clean up applied patch and update references to variables etc. Fix
1444 (TypeContainer::Populate): Update to define all the properties we have. Also

1449 2001-08-31 Ravi Pratap <ravi@che.iitm.ac.in>
1451 * cs-parser.jay (overloadable_operator): The semantic value is an
1452 enum of the Operator class.
1453 (operator_declarator): Implement actions.
1454 (operator_declaration): Implement.

1459 (TypeContainer::AddOperator): New method to add an operator to a type.
1461 * cs-parser.jay (indexer_declaration): Added line to actually call the
1462 AddIndexer method so it gets added ;-)
1464 * ../errors/errors.txt : Update to include new error numbers. Are these numbers
1465 already taken care of by the MS compiler ?
1467 2001-08-29 Ravi Pratap <ravi@che.iitm.ac.in>
1469 * class.cs (Operator): New class for operator declarations.

1482 (catch_clauses): Modify accordingly.
1483 (opt_catch_clauses): New production to use in try_statement
1484 (try_statement): Revamp. Basically, we get rid of one unnecessary rule
1485 and re-write the code in the actions to extract the specific and
1486 general catch clauses by being a little smart ;-)
1488 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
1489 Hooray, try and catch statements parse fine !
1491 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1493 * statement.cs (Block::GetVariableType): Fix logic to extract the type
1494 string from the hashtable of variables.
1496 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did
1497 I end up making that mistake ;-)
1498 (catch_clauses): Fixed gross error which made Key and Value of the
1499 DictionaryEntry the same : $1 !!
1501 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1503 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
1505 * cs-parser.jay (event_declaration): Correct to remove the semicolon
1506 when the add and remove accessors are specified.
1508 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1510 * cs-parser.jay (IndexerDeclaration): New helper class to hold
1511 information about indexer_declarator.
1512 (indexer_declarator): Implement actions.
1513 (parsing_indexer): New local boolean used to keep track of whether
1514 we are parsing indexers or properties. This is necessary because
1515 implicit_parameters come into picture even for the get accessor in the
1517 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
1519 * class.cs (Indexer): New class for indexer declarations.
1520 (TypeContainer::AddIndexer): New method to add an indexer to a type.
1521 (TypeContainer::indexers): New member to hold list of indexers for the
1524 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
1526 * cs-parser.jay (add_accessor_declaration): Implement action.
1527 (remove_accessor_declaration): Implement action.

1541 concatenating all the commas together, just as they appear.
1542 (opt_dim_separators): Modify accordingly
1543 (rank_specifiers): Update accordingly. Basically do the same
1544 thing - instead, collect the brackets here.
1545 (opt_rank_sepcifiers): Modify accordingly.
1546 (array_type): Modify to actually return the complete type string
1547 instead of ignoring the rank_specifiers.
1548 (expression_list): Implement to collect the expressions
1549 (variable_initializer): Implement. We make it a list of expressions
1550 essentially so that we can handle the array_initializer case neatly too.

1552 (array_initializer): Make it a list of variable_initializers
1553 (opt_array_initializer): Modify accordingly.
1555 * expression.cs (New::NType): Add enumeration to help us
1556 keep track of whether we have an object/delegate creation
1557 or an array creation.
1558 (New:NewType, New::Rank, New::Indices, New::Initializers): New
1559 members to hold data about array creation.
1560 (New:New): Modify to update NewType
1561 (New:New): New Overloaded contructor for the array creation
1564 * cs-parser.jay (array_creation_expression): Implement to call

1567 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
1569 * class.cs (TypeContainer::Constructors): Return member
1570 constructors instead of returning null.
1572 2001-08-26 Miguel de Icaza <miguel@ximian.com>
1574 * typemanager.cs (InitCoreTypes): Initialize the various core
1575 types after we have populated the type manager with the user
1576 defined types (this distinction will be important later while
1577 compiling corlib.dll)
1579 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
1580 on Expression Classification. Now all expressions have a method
1581 `Resolve' and a method `Emit'.
1583 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
1584 generation from working. Also add some temporary debugging
1587 2001-08-24 Miguel de Icaza <miguel@ximian.com>
1589 * codegen.cs: Lots of code generation pieces. This is only the
1590 beginning, will continue tomorrow with more touches of polish. We
1591 handle the fundamentals of if, while, do, for, return. Others are
1592 trickier and I need to start working on invocations soon.
1594 * gen-treedump.cs: Bug fix, use s.Increment here instead of
1597 * codegen.cs (EmitContext): New struct, used during code
1598 emission to keep a context. Most of the code generation will be
1601 * cs-parser.jay: Add embedded blocks to the list of statements of
1602 this block. So code generation proceeds in a top down fashion.
1604 2001-08-23 Miguel de Icaza <miguel@ximian.com>
1606 * statement.cs: Add support for multiple child blocks.
1608 2001-08-22 Miguel de Icaza <miguel@ximian.com>
1610 * codegen.cs (EmitCode): New function, will emit the code for a
1611 Block of code given a TypeContainer and its ILGenerator.
1613 * statement.cs (Block): Standard public readonly optimization.
1614 (Block::Block constructors): Link children.
1615 (Block::Child): Child Linker.
1616 (Block::EmitVariables): Emits IL variable declarations.
1618 * class.cs: Drop support for MethodGroups here, delay until
1620 (Method::): Applied the same simplification that I did before, and
1621 move from Properties to public readonly fields.
1622 (Method::ParameterTypes): Returns the parameter types for the
1623 function, and implements a cache that will be useful later when I
1624 do error checking and the semantic analysis on the methods is
1626 (Constructor::GetCallingConvention): Renamed from CallingConvetion
1627 and made a method, optional argument tells whether this is a class
1628 or a structure to apply the `has-this' bit.
1629 (Method::GetCallingConvention): Implement, returns the calling
1631 (Method::Define): Defines the type, a second pass is performed
1632 later to populate the methods.
1634 (Constructor::ParameterTypes): implement a cache similar to the
1635 one on Method::ParameterTypes, useful later when we do semantic
1638 (TypeContainer::EmitMethod): New method. Emits methods.
1640 * expression.cs: Removed MethodGroup class from here.
1642 * parameter.cs (Parameters::GetCallingConvention): new method.

1646 * class.cs (TypeContainer::Populate): Drop RootContext from the
1649 (Constructor::CallingConvention): Returns the calling convention.
1650 (Constructor::ParameterTypes): Returns the constructor parameter
1653 (TypeContainer::AddConstructor): Keep track of default constructor
1654 and the default static constructor.
1656 (Constructor::) Another class that starts using `public readonly'
1657 instead of properties.
1659 (Constructor::IsDefault): Whether this is a default constructor.
1661 (Field::) use readonly public fields instead of properties also.
1663 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
1664 track of static constructors; If none is used, turn on
1665 BeforeFieldInit in the TypeAttributes.
1667 * cs-parser.jay (opt_argument_list): now the return can be null
1668 for the cases where there are no arguments.
1670 (constructor_declarator): If there is no implicit `base' or
1671 `this', then invoke the default parent constructor.
1673 * modifiers.cs (MethodAttr): New static function maps a set of
1674 modifiers flags into a MethodAttributes enum
1675 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
1676 MethodAttr, TypeAttr to represent the various mappings where the
1678 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
1680 2001-08-19 Miguel de Icaza <miguel@ximian.com>
1682 * parameter.cs (GetParameterInfo): Fix bug where there would be no
1685 * interface.cs (PopulateIndexer): Implemented the code generator
1686 for interface indexers.
1688 2001-08-17 Miguel de Icaza <miguel@ximian.com>
1690 * interface.cs (InterfaceMemberBase): Now we track the new status
1693 (PopulateProperty): Implement property population. Woohoo! Got
1694 Methods and Properties going today.
1696 Removed all the properties for interfaces, and replaced them with
1697 `public readonly' fields.
1699 2001-08-16 Miguel de Icaza <miguel@ximian.com>
1701 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
1702 initialize their hashtables/arraylists only when they are needed
1703 instead of doing this always.
1705 * parameter.cs: Handle refs and out parameters.
1707 * cs-parser.jay: Use an ArrayList to construct the arguments
1708 instead of the ParameterCollection, and then cast that to a
1711 * parameter.cs: Drop the use of ParameterCollection and use
1712 instead arrays of Parameters.
1714 (GetParameterInfo): Use the Type, not the Name when resolving
1717 2001-08-13 Miguel de Icaza <miguel@ximian.com>
1719 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
1720 and instead use public readonly fields.
1722 * class.cs: Put back walking code for type containers.
1724 2001-08-11 Miguel de Icaza <miguel@ximian.com>
1726 * class.cs (MakeConstant): Code to define constants.
1728 * rootcontext.cs (LookupType): New function. Used to locate types
1731 2001-08-08 Miguel de Icaza <miguel@ximian.com>
1733 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
1734 this System.Reflection code is. Kudos to Microsoft
1736 * typemanager.cs: Implement a type cache and avoid loading all
1737 types at boot time. Wrap in LookupType the internals. This made
1738 the compiler so much faster. Wow. I rule!
1740 * driver.cs: Make sure we always load mscorlib first (for
1741 debugging purposes, nothing really important).
1743 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1744 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
1746 * rootcontext.cs: Lookup types on their namespace; Lookup types
1747 on namespaces that have been imported using the `using' keyword.
1749 * class.cs (TypeContainer::TypeAttr): Virtualize.
1750 (Class::TypeAttr): Return attributes suitable for this bad boy.
1751 (Struct::TypeAttr): ditto.
1752 Handle nested classes.
1753 (TypeContainer::) Remove all the type visiting code, it is now
1754 replaced with the rootcontext.cs code
1756 * rootcontext.cs (GetClassBases): Added support for structs.
1758 2001-08-06 Miguel de Icaza <miguel@ximian.com>
1760 * interface.cs, statement.cs, class.cs, parameter.cs,
1761 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
1762 Drop use of TypeRefs, and use strings instead.
1764 2001-08-04 Miguel de Icaza <miguel@ximian.com>
1768 * class.cs (Struct::Struct): set the SEALED flags after
1769 checking the modifiers.
1770 (TypeContainer::TypeAttr): new property, returns the
1771 TypeAttributes for a class.
1773 * cs-parser.jay (type_list): Oops, list production was creating a
1774 new list of base types.
1776 * rootcontext.cs (StdLib): New property.
1777 (GetInterfaceTypeByName): returns an interface by type name, and
1778 encapsulates error handling here.
1779 (GetInterfaces): simplified.
1780 (ResolveTree): Encapsulated all the tree resolution here.
1781 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
1784 * driver.cs: Add support for --nostdlib, to avoid loading the
1786 (Main): Do not put tree resolution here.
1788 * rootcontext.cs: Beginning of the class resolution.
1790 2001-08-03 Miguel de Icaza <miguel@ximian.com>
1792 * rootcontext.cs: Provide better error reporting.
1794 * cs-parser.jay (interface_base): set our $$ to be interfaces.
1796 * rootcontext.cs (CreateInterface): Handle the case where there
1797 are no parent interfaces.
1799 (CloseTypes): Routine to flush types at the end.
1800 (CreateInterface): Track types.
1801 (GetInterfaces): Returns an array of Types from the list of
1804 * typemanager.c (AddUserType): Mechanism to track user types (puts
1805 the type on the global type hash, and allows us to close it at the
1808 2001-08-02 Miguel de Icaza <miguel@ximian.com>
1810 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
1811 RecordInterface instead.
1813 * cs-parser.jay: Updated to reflect changes above.
1815 * decl.cs (Definition): Keep track of the TypeBuilder type that
1816 represents this type here. Not sure we will use it in the long
1817 run, but wont hurt for now.
1819 * driver.cs: Smaller changes to accomodate the new code.
1821 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
1824 * rootcontext.cs (CreateInterface): New method, used to create
1825 the System.TypeBuilder type for interfaces.
1826 (ResolveInterfaces): new entry point to resolve the interface
1828 (CodeGen): Property, used to keep track of the code generator.
1830 2001-07-26 Miguel de Icaza <miguel@ximian.com>
1832 * cs-parser.jay: Add a second production for delegate_declaration
1835 (enum_body): Put an opt_comma here instead of putting it on
1836 enum_body or enum_member_declarations so we can handle trailing
1837 commas on enumeration members. Gets rid of a shift/reduce.
1839 (type_list): Need a COMMA in the middle.
1841 (indexer_declaration): Tell tokenizer to recognize get/set
1843 * Remove old targets.
1845 * Re-add the parser target.
1847 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1849 * cs-parser.jay: Add precendence rules for a number of operators
1850 ot reduce the number of shift/reduce conflicts in the grammar.
1852 2001-07-17 Miguel de Icaza <miguel@ximian.com>
1854 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
1857 Get rid of old crufty code.
1859 * rootcontext.cs: Use this to keep track of the parsed
1860 representation and the defined types available to the program.
1862 * gen-treedump.cs: adjust for new convention.
1864 * type.cs: Split out the type manager, and the assembly builder
1867 * typemanager.cs: the type manager will live here now.
1869 * cil-codegen.cs: And the code generator here.

1873 * makefile: Fixed up for easy making.
1875 2001-07-13 Simon Cozens <simon@simon-cozens.org>
1877 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
1880 (unary_expression): Expand pre_increment_expression and
1881 post_decrement_expression to reduce a shift/reduce.
1883 2001-07-11 Simon Cozens
1885 * cs-tokenizer.cs: Hex numbers should begin with a 0.
1887 Improve allow_keyword_as_indent name.
1889 2001-06-19 Miguel de Icaza <miguel@ximian.com>
1891 * Adjustments for Beta2.
1893 2001-06-13 Miguel de Icaza <miguel@ximian.com>
1895 * decl.cs: Added `Define' abstract method.
1896 (InTransit): new property, used to catch recursive definitions.
1898 * interface.cs: Implement `Define'.
1900 * modifiers.cs: Map Modifiers.constants to
1901 System.Reflection.TypeAttribute flags.
1903 * class.cs: Keep track of types and user-defined types.
1904 (BuilderInit): New method for creating an assembly
1905 (ResolveType): New function to launch the resolution process, only
1906 used by interfaces for now.
1908 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
1909 that are inserted into the name space.
1911 2001-06-08 Miguel de Icaza <miguel@ximian.com>
1913 * ARGH. I have screwed up my tree so many times due to the use of
1914 rsync rather than using CVS. Going to fix this at once.
1916 * driver.cs: Objetify driver. Load assemblies, use assemblies to
1919 2001-06-07 Miguel de Icaza <miguel@ximian.com>
1921 * Experiment successful: Use System.Type rather that our own
1924 2001-05-25 Miguel de Icaza <miguel@ximian.com>
1926 * cs-parser.jay: Removed nsAliases from here.
1928 Use new namespaces, handle `using XXX;'
1930 * namespace.cs: Reimplemented namespace handling, use a recursive
1931 definition of the class. Now we can keep track of using clauses
1932 and catch invalid using clauses.
1934 2001-05-24 Miguel de Icaza <miguel@ximian.com>
1936 * gen-treedump.cs: Adapted for all the renaming.
1938 * expression.cs (Expression): this class now has a Type property
1939 which returns an expression Type.
1941 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
1942 `Type', as this has a different meaning now in the base
1944 2001-05-22 Miguel de Icaza <miguel@ximian.com>
1946 * interface.cs, class.cs: Removed from all the sources the
1947 references to signature computation, as we can not do method
1948 signature computation during the parsing time, as we are not
1949 trying to solve at that point distinguishing:
1953 void a (NS.Blah x) {}
1956 Which depending on the context might be valid or not, as we do not
1957 know if Blah is the same thing as NS.Blah at that point.
1959 * Redid everything so the code uses TypeRefs now instead of
1960 Types. TypeRefs are just temporary type placeholders, that need
1961 to be resolved. They initially have a pointer to a string and the
1962 current scope in which they are used. This is used later by the
1963 compiler to resolve the reference to an actual Type.
1965 * DeclSpace is no longer a CIR.Type, and neither are
1966 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
1967 are all DeclSpaces, but no Types.
1969 * type.cs (TypeRefManager): This implements the TypeRef manager,
1970 which keeps track of all the types that need to be resolved after
1971 the parsing has finished.
1973 2001-05-13 Miguel de Icaza <miguel@ximian.com>
1975 * ARGH. We are going to have to store `foreach' as a class rather
1976 than resolving it, as we need to verify error 1579 after name
1977 resolution. *OR* we could keep a flag that says `This request to
1978 IEnumerator comes from a foreach statement' which we can then use
1979 to generate the error.
1981 2001-05-10 Miguel de Icaza <miguel@ximian.com>
1983 * class.cs (TypeContainer.AddMethod): we now add methods to the
1984 MethodGroup instead of the method hashtable.
1986 * expression.cs: Add MethodGroup abstraction, which gets us one
1987 step closer to the specification in the way we handle method
1990 * cs-parser.jay (primary_expression): qualified_identifier now
