6 * typemanager.cs (IsInterfaceType): Implement.
8 (FindMembers): Update to handle interface types too.
10 * expression.cs (ImplicitReferenceConversion): Re-write bits which
11 use IsAssignableFrom as that is not correct - it doesn't work.

17 using the correct logic :-)

147 2001-10-15 Ravi Pratap <ravi@ximian.com>
149 * delegate.cs (Emit): Get rid of it as there doesn't seem to be any ostensible

175 * cs-parser.jay (delegate_declaration): Fixed the bug that I had introduced :-)
176 Qualify the name of the delegate, not its return type !
178 * expression.cs (ImplicitReferenceConversion): Implement guts of implicit array

189 * cs-parser.jay (delegate_declaration): Store the fully qualified
190 name as it is a type declaration.
192 * delegate.cs (ReturnType, Name): Rename members to these. Make them

196 as TypeContainer::DefineType.
198 (Populate): Method in which all the definition of the various methods (Invoke)

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

233 2001-10-12 Miguel de Icaza <miguel@ximian.com>
235 * expression.cs: PropertyExpr::PropertyExpr: use work around the

248 (This::LValueResolve): Implement.
250 (This::Store): Remove warning, assigning to `this' in structures
253 (Invocation::Emit): Deal with invocation of
254 methods on value types. We need to pass the address to structure
255 methods rather than the object itself. (The equivalent code to
256 emit "this" for structures leaves the entire structure on the
257 stack instead of a pointer to it).
259 (ParameterReference::DoResolve): Compute the real index for the
260 argument based on whether the method takes or not a `this' pointer
261 (ie, the method is static).

270 * class.cs (TypeContainer::DefineType): Method to actually do the business of
271 defining the type in the Modulebuilder or Typebuilder. This is to take
272 care of nested types which need to be defined on the TypeBuilder using
275 (TypeContainer::GetClassBases): Implement. Essentially the code from the
276 methods in RootContext, only ported to be part of TypeContainer.
278 (TypeContainer::GetInterfaceOrClass): Ditto.
280 (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
282 * interface.cs (Interface::DefineInterface): New method. Does exactly

294 * class.cs (TypeContainer::Populate): Populate nested types too.
295 (TypeContainer::Emit): Emit nested members too.
297 * typemanager.cs (AddUserType): Do not make use of the FullName property,
298 instead just use the name argument passed in as it is already fully
301 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
302 to TypeContainer mapping to see if a type is user-defined.
304 * class.cs (TypeContainer::CloseType): Implement.

307 the default constructor.
309 (TypeContainer::Populate): Fix minor bug which led to creating default constructors

334 expected return type.
336 Validate use of return statement.
338 * codegen.cs (EmitContext): Pass the expected return type here.
340 * class.cs (Method, Constructor, Property): Pass expected return
343 2001-10-09 Miguel de Icaza <miguel@ximian.com>
345 * expression.cs: Make DoResolve take an EmitContext instead of a
348 Replaced `l' and `location' for `loc', for consistency.
350 (Error, Warning): Remove unneeded Tc argument.
352 * assign.cs, literal.cs, constant.cs: Update to new calling
355 * codegen.cs: EmitContext now contains a flag indicating whether
356 code is being generated in a static method or not.
358 * cs-parser.jay: DecomposeQI, new function that replaces the old
359 QualifiedIdentifier. Now we always decompose the assembled
360 strings from qualified_identifier productions into a group of
363 2001-10-08 Miguel de Icaza <miguel@ximian.com>
365 * rootcontext.cs: Deal with field-less struct types correctly now
366 by passing the size option to Define Type.
368 * class.cs: Removed hack that created one static field.
370 2001-10-07 Miguel de Icaza <miguel@ximian.com>
372 * statement.cs: Moved most of the code generation here.

384 * expression.cs (ElementAccess::DoResolve): Remove my crap code
385 and start performing checks according to the spec.
387 2001-10-07 Ravi Pratap <ravi@ximian.com>
389 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
390 rank_specifiers instead.
392 (rank_specifiers): Change the order in which the rank specifiers are stored
394 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
396 * expression.cs (ElementAccess): Implement the LValue interface too.

422 * cs-parser.jay: Added support for try/catch/finalize.
424 * class.cs: Catch static methods having the flags override,
427 * expression.cs (UserCast): This user cast was not really doing
428 what it was supposed to do. Which is to be born in fully resolved
429 state. Parts of the resolution were being performed at Emit time!
433 2001-10-05 Miguel de Icaza <miguel@ximian.com>
435 * expression.cs: Implicity convert the result from UserCast.
437 2001-10-05 Ravi Pratap <ravi@ximian.com>
439 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
440 prevented it from working correctly.

468 (UserDefinedConversion): Incorporate support for user defined explicit conversions.
470 (ExplicitUserConversion): Make it a call to UserDefinedConversion
471 with the appropriate arguments.
473 * cs-parser.jay (cast_expression): Record location too.
475 * expression.cs (Cast): Record location info.
477 (Expression::ConvertExplicit): Take location argument.
479 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
480 to determine if we are doing explicit conversions.
482 (UserCast::Emit): Update accordingly.
484 (Expression::ConvertExplicit): Report an error if everything fails.
486 * ../errors/cs0030.cs : Add.
488 2001-10-04 Miguel de Icaza <miguel@ximian.com>
490 * modifiers.cs: If the ABSTRACT keyword is present, also set the
491 virtual and newslot bits.
493 * class.cs (TypeContainer::RegisterRequiredImplementations):
494 Record methods we need.
496 (TypeContainer::MakeKey): Helper function to make keys for
497 MethodBases, since the Methodbase key is useless.
499 (TypeContainer::Populate): Call RegisterRequiredImplementations
500 before defining the methods.
502 Create a mapping for method_builders_to_methods ahead of time
503 instead of inside a tight loop.
505 (::RequireMethods): Accept an object as the data to set into the
506 hashtable so we can report interface vs abstract method mismatch.
508 2001-10-03 Miguel de Icaza <miguel@ximian.com>
510 * report.cs: Make all of it static.
512 * rootcontext.cs: Drop object_type and value_type computations, as
513 we have those in the TypeManager anyways.
515 Drop report instance variable too, now it is a global.
517 * driver.cs: Use try/catch on command line handling.
519 Add --probe option to debug the error reporting system with a test
522 * report.cs: Add support for exiting program when a probe
523 condition is reached.
525 2001-10-03 Ravi Pratap <ravi@ximian.com>
527 * expression.cs (Binary::DoNumericPromotions): Fix the case when

539 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
540 case of a non-null MethodInfo object with a length of 0 !

543 an applicable member - according to the spec :-)
544 Also fix logic to find members in base types.
546 (Unary::ResolveOperator): Same here.
548 (Unary::report23): Change name to error23 and make first argument a TypeContainer
549 as I was getting thoroughly confused between this and error19 :-)

552 (::FindMostEncompassedType): Implement.
553 (::FindMostEncompassingType): Implement.
554 (::StandardConversionExists): Implement.

557 source and target types so that we can do the necessary conversions.
559 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
560 mathematical union with no duplicates.
562 2001-10-03 Miguel de Icaza <miguel@ximian.com>
564 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
565 in order from base classes to child classes, so that we can in
566 child classes look up in our parent for method names and
567 attributes (required for handling abstract, virtual, new, override
568 constructs: we need to instrospect our base class, and if we dont
569 populate the classes in order, the introspection might be
570 incorrect. For example, a method could query its parent before
571 the parent has any methods and would determine that the parent has
572 no abstract methods (while it could have had them)).
574 (RootContext::CreateType): Record the order in which we define the
577 2001-10-02 Miguel de Icaza <miguel@ximian.com>

601 * class.cs (Property::Emit): Generate code for properties.
603 2001-10-02 Ravi Pratap <ravi@ximian.com>
605 * expression.cs (Unary::ResolveOperator): Find operators on base type
606 too - we now conform exactly to the spec.
608 (Binary::ResolveOperator): Same here.
610 * class.cs (Operator::Define): Fix minor quirk in the tests.
612 * ../errors/cs0215.cs : Added.

626 even in the case when we are examining True operators.

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

637 (cloneable_interface): For System.ICloneable interface.
639 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
640 we start resolving the tree and populating types.
642 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
644 2001-10-01 Miguel de Icaza <miguel@ximian.com>
646 * expression.cs (Expression::ExprClassFromMemberInfo,
647 Expression::Literalize): Create literal expressions from
648 FieldInfos which are literals.
650 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
651 type casts, because they were wrong. The test suite in tests
654 (ImplicitNumericConversion): ushort to ulong requires a widening
657 Int32 constant to long requires widening cast as well.
659 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
660 for integers because the type on the stack is not i4.
662 2001-09-30 Miguel de Icaza <miguel@ximian.com>
664 * expression.cs (report118): require location argument.
666 * parameter.cs: Do not dereference potential null value.
668 * class.cs: Catch methods that lack the `new' keyword when
669 overriding a name. Report warnings when `new' is used without
670 anything being there to override.
672 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
674 * class.cs: Only add constructor to hashtable if it is non-null
675 (as now constructors can fail on define).
677 (TypeManager, Class, Struct): Take location arguments.
679 Catch field instance initialization in structs as errors.
681 accepting_filter: a new filter for FindMembers that is static so
682 that we dont create an instance per invocation.
684 (Constructor::Define): Catch errors where a struct constructor is
687 * cs-parser.jay: Pass location information for various new
690 * delegate.cs (Delegate): take a location argument.
692 * driver.cs: Do not call EmitCode if there were problesm in the
693 Definition of the types, as many Builders wont be there.
695 * decl.cs (Decl::Decl): Require a location argument.
697 * cs-tokenizer.cs: Handle properly hex constants that can not fit
698 into integers, and find the most appropiate integer for it.
700 * literal.cs: Implement ULongLiteral.
702 * rootcontext.cs: Provide better information about the location of
703 failure when CreateType fails.
705 2001-09-29 Miguel de Icaza <miguel@ximian.com>
707 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
710 * expression.cs (Binary::CheckShiftArguments): Add missing type
712 (Binary::ResolveOperator): Add type to the logical and and logical
713 or, Bitwise And/Or and Exclusive Or code paths, it was missing
716 (Binary::DoNumericPromotions): In the case where either argument
717 is ulong (and most signed types combined with ulong cause an
718 error) perform implicit integer constant conversions as well.
720 2001-09-28 Miguel de Icaza <miguel@ximian.com>
722 * expression.cs (UserImplicitCast): Method should always be
724 (Invocation::BetterConversion): Simplified test for IntLiteral.
726 (Expression::ImplicitNumericConversion): Split this routine out.
727 Put the code that performs implicit constant integer conversions
730 (Expression::Resolve): Become a wrapper around DoResolve so we can
731 check eclass and type being set after resolve.
733 (Invocation::Badness): Remove this dead function
735 (Binary::ResolveOperator): Do not compute the expensive argumnets
736 unless we have a union for it.
738 (Probe::Emit): Is needs to do an isinst and then
739 compare against null.
741 (::CanConvert): Added Location argument. If the Location argument
742 is null (Location.Null), then we do not report errors. This is
743 used by the `probe' mechanism of the Explicit conversion. We do
744 not want to generate an error for something that the user
745 explicitly requested to be casted. But the pipeline for an
746 explicit cast first tests for potential implicit casts.
748 So for now, if the Location is null, it means `Probe only' to
749 avoid adding another argument. Might have to revise this
752 (ClassCast): New class used to type cast objects into arbitrary
753 classes (used in Explicit Reference Conversions).
755 Implement `as' as well.
757 Reverted all the patches from Ravi below: they were broken:
759 * The use of `level' as a mechanism to stop recursive
760 invocations is wrong. That was there just to catch the
761 bug with a strack trace but not as a way of addressing
764 To fix the problem we have to *understand* what is going
765 on and the interactions and come up with a plan, not
766 just get things going.
768 * The use of the type conversion cache that I proposed
769 last night had an open topic: How does this work across
770 protection domains. A user defined conversion might not
771 be public in the location where we are applying the
772 conversion, a different conversion might be selected
773 (ie, private A->B (better) but public B->A (worse),
774 inside A, A->B applies, but outside it, B->A will
777 * On top of that (ie, even if the above is solved),
778 conversions in a cache need to be abstract. Ie, `To
779 convert from an Int to a Short use an OpcodeCast', not
780 `To convert from an Int to a Short use the OpcodeCast on
781 the variable 5' (which is what this patch was doing).
783 2001-09-28 Ravi Pratap <ravi@ximian.com>
785 * expression.cs (Invocation::ConversionExists): Re-write to use
788 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
789 cache all conversions done, not just user-defined ones.
791 (Invocation::BetterConversion): The real culprit. Use ConversionExists
792 to determine if a conversion exists instead of acutually trying to
793 perform the conversion. It's faster too.
795 (Expression::ConvertExplicit): Modify to use ConversionExists to check
796 and only then attempt the implicit conversion.
798 2001-09-28 Ravi Pratap <ravi@ximian.com>
800 * expression.cs (ConvertImplicit): Use a cache for conversions
801 already found. Check level of recursion and bail out if necessary.

820 Fix the order in which implicit conversions are
823 The previous fixed dropped support for boxed conversions (adding a
824 test to the test suite now)
826 (UserImplicitCast::CanConvert): Remove test for source being null,
827 that code is broken. We should not feed a null to begin with, if
828 we do, then we should track the bug where the problem originates
829 and not try to cover it up here.
831 Return a resolved expression of type UserImplicitCast on success
832 rather than true/false. Ravi: this is what I was talking about,
833 the pattern is to use a static method as a "constructor" for
836 Also, do not create arguments until the very last minute,
837 otherwise we always create the arguments even for lookups that
838 will never be performed.
840 (UserImplicitCast::Resolve): Eliminate, objects of type
841 UserImplicitCast are born in a fully resolved state.
843 * typemanager.cs (InitCoreTypes): Init also value_type
846 * expression.cs (Cast::Resolve): First resolve the child expression.
848 (LValue): Add new method AddressOf to be used by
851 Change the argument of Store to take an EmitContext instead of an
852 ILGenerator, because things like FieldExpr need to be able to call
853 their children expression to generate the instance code.
855 (Expression::Error, Expression::Warning): Sugar functions for
858 (Expression::MemberLookup): Accept a TypeContainer instead of a
859 Report as the first argument.
861 (Expression::ResolvePrimary): Killed. I still want to improve
862 this as currently the code is just not right.
864 (Expression::ResolveMemberAccess): Simplify, but it is still
867 (Unary::Resolve): Catch errors in AddressOf operators.
869 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
870 index to a byte for the short-version, or the compiler will choose
871 the wrong Emit call, which generates the wrong data.
873 (ParameterReference::Emit, ::Store): same.
875 (FieldExpr::AddressOf): Implement.
877 * typemanager.cs: TypeManager: made public variable instead of
880 * driver.cs: document --fatal.
882 * report.cs (ErrorMessage, WarningMessage): new names for the old
883 Error and Warning classes.

906 (ConvertImplicit): Call CanConvert and only then create object if necessary.
907 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
909 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
910 that is the right way.
912 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
913 overloading resolution. Use everywhere instead of cutting and pasting code.
915 (Binary::ResolveOperator): Use MakeUnionSet.
917 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
918 we have to convert to bool types. Not complete yet.

927 (Expression::ConvertImplicitRequired): Reworked to include
928 implicit constant expression conversions.
930 (Expression::ConvertNumericExplicit): Finished.
932 (Invocation::Emit): If InstanceExpression is null, then it means

937 * expression.cs (Unary::Emit): Remove some dead code.
938 (Probe): Implement Resolve and Emit for `is'.
939 (Expression::ConvertImplicitRequired): Attempt to do constant
940 expression conversions here. Maybe should be moved to
941 ConvertImplicit, but I am not sure.

943 Expression::ImplicitIntConstantConversionPossible): New functions
944 that tell whether is it possible to apply an implicit constant
945 expression conversion.

958 ones that the spec expects (as we are just stringizing the
961 * expression.cs (Unary::ResolveOperator): Fix bug: Use
962 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
963 previous usage did only work for our methods.
964 (Expression::ConvertImplicit): Handle decimal implicit numeric
966 (Expression::InternalTypeConstructor): Used to invoke constructors
967 on internal types for default promotions.
969 (Unary::Emit): Implement special handling for the pre/post
970 increment/decrement for overloaded operators, as they need to have
971 the same semantics as the other operators.

994 expressions that can appear in statements, so that we can provide
995 an alternate path to generate expression that do not leave a value
998 (Expression::Emit, and all the derivatives): We no longer return
999 whether a value is left on the stack or not. Every expression
1000 after being emitted leaves a single value on the stack.
1002 * codegen.cs (EmitContext::EmitStatementExpression): Use the
1003 facilties of ExpressionStatement if possible.

1030 * assign.cs: track location.
1031 (Resolve): Use implicit conversions on assignment.

1096 * typemanager.cs: declare and load enum_type, delegate_type and
1099 * expression.cs (Expression::Emit): Now emit returns a value that

1237 initializer for static and instance variables.

1295 (Expression::MemberLookup): Provide a version that allows to
1296 specify the MemberTypes and BindingFlags.

1302 Beforefieldinit as it was buggy.
1304 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
1307 * class.cs (Constructor::Emit): Only emit if block is not null.
1308 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
1309 deal with this by semantically definining it as if the user had

1417 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
1418 incorrect. IsTopLevel is not used to tell whether an object is
1419 root_types or not (that can be achieved by testing this ==
1420 root_types). But to see if this is a top-level *class* (not
1421 necessarly our "toplevel" container).
1423 2001-09-14 Ravi Pratap <ravi@ximian.com>
1425 * enum.cs (Enum::Define): Modify to call the Lookup method on the
1426 parent instead of a direct call to GetType.
1428 2001-09-14 Ravi Pratap <ravi@ximian.com>
1430 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
1431 Modifiers.TypeAttr. This should just be a call to that method.
1433 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
1434 object so that we can determine if we are top-level or not.
1436 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
1439 * enum.cs (Enum::Define): Ditto.
1441 * modifiers.cs (FieldAttr): Re-write.

1444 (TypeContainer::HaveStaticConstructor): New property to provide access
1445 to precisely that info.
1447 * modifiers.cs (MethodAttr): Re-write.
1448 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
1450 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
1451 of top-level types as claimed.
1453 2001-09-13 Miguel de Icaza <miguel@ximian.com>
1455 * expression.cs (MemberLookup): Fruitless attempt to lookup
1456 constructors. Maybe I need to emit default constructors? That

1459 (Invocation::EmitArguments): new function, shared by the new

1481 objects that we might have around.
1483 (Populate): Only initialize method_builders_to_methods once.
1485 * expression.cs (PropertyExpr): Initialize type from the
1488 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

1493 (Binary::ResolveOperator): Set the return type to boolean for
1494 comparission operators

1501 elsewhere depends on the test to reflect the correct contents.
1503 (Method::) Keep track of parameters, due to System.Reflection holes
1505 (TypeContainer::Populate): Keep track of MethodBuilders to Method
1508 (TypeContainer::FindMembers): Use ArrayList and then copy an array
1509 of the exact size and return that.
1511 (Class::LookupMethodByBuilder): New function that maps
1512 MethodBuilders to its methods. Required to locate the information
1513 on methods because System.Reflection bit us again.
1515 * support.cs: New file, contains an interface ParameterData and
1516 two implementations: ReflectionParameters and InternalParameters
1517 used to access Parameter information. We will need to grow this
1520 * expression.cs (Invocation::GetParameterData): implement a cache
1521 and a wrapper around the ParameterData creation for methods.
1522 (Invocation::OverloadResolve): Use new code.
1524 2001-09-13 Ravi Pratap <ravi@ximian.com>

1578 2001-09-12 Ravi Pratap <ravi@ximian.com>
1580 * class.cs (TypeContainer::FindMembers): Method which does exactly
1581 what Type.FindMembers does, only we don't have to use reflection. No
1584 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
1585 typecontainer objects as we need to get at them.
1586 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

1613 (Event::Define): Ditto.
1614 (Property::Define): Ditto.
1616 2001-09-10 Ravi Pratap <ravi@ximian.com>
1618 * class.cs (TypeContainer::Populate): Now define operators too.
1619 (TypeContainer.Operators): New property to access the list of operators
1621 (Operator.OperatorMethodBuilder): New member to hold the method builder
1622 for the operator we are defining.

1627 * class.cs (Event::Define): Make the prefixes of the accessor methods
1628 addOn_ and removeOn_
1630 * genericparser.cs (GenericParser::error): Overloaded method to handle the case

1632 error reporting should be done through the Report object.
1634 * class.cs (TypeContainer.Indexers): New property to access the list of indexers.
1635 (Populate): Iterate thru the indexers we have and define them too.

1677 (CheckBinaryOperator): Same here.
1679 * rootcontext.cs (LookupType): Add an extra lookup which simply does a lookup
1680 on the name without any prefixes of namespace names etc. This is because we
1681 already might have something already fully qualified like
1682 'System.Console.WriteLine'

1833 will is used during the tree rewriting as we resolve them during
1836 (Expression::MemberLookup): Implements the MemberLookup (7.3) from

1842 a MemberInfo that is one of Eventinfo, FieldINfo, PropertyInfo or

1960 * class.cs (Property): Revamp to use the convention of making fields readonly.

2009 and re-write the code in the actions to extract the specific and
2010 general catch clauses by being a little smart ;-)
2012 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
2013 Hooray, try and catch statements parse fine !
2015 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2017 * statement.cs (Block::GetVariableType): Fix logic to extract the type
2018 string from the hashtable of variables.
2020 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did

2022 (catch_clauses): Fixed gross error which made Key and Value of the

2039 implicit_parameters come into picture even for the get accessor in the
2041 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
2043 * class.cs (Indexer): New class for indexer declarations.
2044 (TypeContainer::AddIndexer): New method to add an indexer to a type.
2045 (TypeContainer::indexers): New member to hold list of indexers for the
2048 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
2050 * cs-parser.jay (add_accessor_declaration): Implement action.
2051 (remove_accessor_declaration): Implement action.
2052 (event_accessors_declaration): Implement
2053 (variable_declarators): swap statements for first rule - trivial.
2055 * class.cs (Event): New class to hold information about event
2057 (TypeContainer::AddEvent): New method to add an event to a type
2058 (TypeContainer::events): New member to hold list of events.
2060 * cs-parser.jay (event_declaration): Implement actions.
2062 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
2064 * cs-parser.jay (dim_separators): Implement. Make it a string
2065 concatenating all the commas together, just as they appear.
2066 (opt_dim_separators): Modify accordingly
2067 (rank_specifiers): Update accordingly. Basically do the same
2068 thing - instead, collect the brackets here.
2069 (opt_rank_sepcifiers): Modify accordingly.
2070 (array_type): Modify to actually return the complete type string
2071 instead of ignoring the rank_specifiers.
2072 (expression_list): Implement to collect the expressions
2073 (variable_initializer): Implement. We make it a list of expressions
2074 essentially so that we can handle the array_initializer case neatly too.
2075 (variable_initializer_list): Implement.
2076 (array_initializer): Make it a list of variable_initializers
2077 (opt_array_initializer): Modify accordingly.
2079 * expression.cs (New::NType): Add enumeration to help us
2080 keep track of whether we have an object/delegate creation
2081 or an array creation.
2082 (New:NewType, New::Rank, New::Indices, New::Initializers): New
2083 members to hold data about array creation.
2084 (New:New): Modify to update NewType
2085 (New:New): New Overloaded contructor for the array creation
2088 * cs-parser.jay (array_creation_expression): Implement to call
2089 the overloaded New constructor.
2091 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
2093 * class.cs (TypeContainer::Constructors): Return member
2094 constructors instead of returning null.
2096 2001-08-26 Miguel de Icaza <miguel@ximian.com>
2098 * typemanager.cs (InitCoreTypes): Initialize the various core
2099 types after we have populated the type manager with the user
2100 defined types (this distinction will be important later while
2101 compiling corlib.dll)
2103 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
2104 on Expression Classification. Now all expressions have a method
2105 `Resolve' and a method `Emit'.
2107 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
2108 generation from working. Also add some temporary debugging
2111 2001-08-24 Miguel de Icaza <miguel@ximian.com>
2113 * codegen.cs: Lots of code generation pieces. This is only the
2114 beginning, will continue tomorrow with more touches of polish. We
2115 handle the fundamentals of if, while, do, for, return. Others are
2116 trickier and I need to start working on invocations soon.
2118 * gen-treedump.cs: Bug fix, use s.Increment here instead of
2121 * codegen.cs (EmitContext): New struct, used during code
2122 emission to keep a context. Most of the code generation will be
2125 * cs-parser.jay: Add embedded blocks to the list of statements of
2126 this block. So code generation proceeds in a top down fashion.
2128 2001-08-23 Miguel de Icaza <miguel@ximian.com>
2130 * statement.cs: Add support for multiple child blocks.
2132 2001-08-22 Miguel de Icaza <miguel@ximian.com>
2134 * codegen.cs (EmitCode): New function, will emit the code for a
2135 Block of code given a TypeContainer and its ILGenerator.
2137 * statement.cs (Block): Standard public readonly optimization.
2138 (Block::Block constructors): Link children.
2139 (Block::Child): Child Linker.
2140 (Block::EmitVariables): Emits IL variable declarations.
2142 * class.cs: Drop support for MethodGroups here, delay until
2144 (Method::): Applied the same simplification that I did before, and
2145 move from Properties to public readonly fields.
2146 (Method::ParameterTypes): Returns the parameter types for the
2147 function, and implements a cache that will be useful later when I
2148 do error checking and the semantic analysis on the methods is
2150 (Constructor::GetCallingConvention): Renamed from CallingConvetion
2151 and made a method, optional argument tells whether this is a class
2152 or a structure to apply the `has-this' bit.
2153 (Method::GetCallingConvention): Implement, returns the calling
2155 (Method::Define): Defines the type, a second pass is performed
2156 later to populate the methods.
2158 (Constructor::ParameterTypes): implement a cache similar to the
2159 one on Method::ParameterTypes, useful later when we do semantic
2162 (TypeContainer::EmitMethod): New method. Emits methods.
2164 * expression.cs: Removed MethodGroup class from here.
2166 * parameter.cs (Parameters::GetCallingConvention): new method.
2168 2001-08-21 Miguel de Icaza <miguel@ximian.com>
2170 * class.cs (TypeContainer::Populate): Drop RootContext from the
2173 (Constructor::CallingConvention): Returns the calling convention.
2174 (Constructor::ParameterTypes): Returns the constructor parameter
2177 (TypeContainer::AddConstructor): Keep track of default constructor
2178 and the default static constructor.
2180 (Constructor::) Another class that starts using `public readonly'
2181 instead of properties.
2183 (Constructor::IsDefault): Whether this is a default constructor.
2185 (Field::) use readonly public fields instead of properties also.
2187 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
2188 track of static constructors; If none is used, turn on
2189 BeforeFieldInit in the TypeAttributes.
2191 * cs-parser.jay (opt_argument_list): now the return can be null
2192 for the cases where there are no arguments.
2194 (constructor_declarator): If there is no implicit `base' or
2195 `this', then invoke the default parent constructor.
2197 * modifiers.cs (MethodAttr): New static function maps a set of
2198 modifiers flags into a MethodAttributes enum
2199 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
2200 MethodAttr, TypeAttr to represent the various mappings where the
2202 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
2204 2001-08-19 Miguel de Icaza <miguel@ximian.com>
2206 * parameter.cs (GetParameterInfo): Fix bug where there would be no
2209 * interface.cs (PopulateIndexer): Implemented the code generator
2210 for interface indexers.
2212 2001-08-17 Miguel de Icaza <miguel@ximian.com>
2214 * interface.cs (InterfaceMemberBase): Now we track the new status
2217 (PopulateProperty): Implement property population. Woohoo! Got
2218 Methods and Properties going today.
2220 Removed all the properties for interfaces, and replaced them with
2221 `public readonly' fields.
2223 2001-08-16 Miguel de Icaza <miguel@ximian.com>
2225 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
2226 initialize their hashtables/arraylists only when they are needed
2227 instead of doing this always.
2229 * parameter.cs: Handle refs and out parameters.
2231 * cs-parser.jay: Use an ArrayList to construct the arguments
2232 instead of the ParameterCollection, and then cast that to a
2235 * parameter.cs: Drop the use of ParameterCollection and use
2236 instead arrays of Parameters.
2238 (GetParameterInfo): Use the Type, not the Name when resolving
2241 2001-08-13 Miguel de Icaza <miguel@ximian.com>
2243 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
2244 and instead use public readonly fields.
2246 * class.cs: Put back walking code for type containers.
2248 2001-08-11 Miguel de Icaza <miguel@ximian.com>
2250 * class.cs (MakeConstant): Code to define constants.
2252 * rootcontext.cs (LookupType): New function. Used to locate types
2255 2001-08-08 Miguel de Icaza <miguel@ximian.com>
2257 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
2258 this System.Reflection code is. Kudos to Microsoft
2260 * typemanager.cs: Implement a type cache and avoid loading all
2261 types at boot time. Wrap in LookupType the internals. This made
2262 the compiler so much faster. Wow. I rule!
2264 * driver.cs: Make sure we always load mscorlib first (for
2265 debugging purposes, nothing really important).
2267 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
2268 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
2270 * rootcontext.cs: Lookup types on their namespace; Lookup types
2271 on namespaces that have been imported using the `using' keyword.
2273 * class.cs (TypeContainer::TypeAttr): Virtualize.
2274 (Class::TypeAttr): Return attributes suitable for this bad boy.
2275 (Struct::TypeAttr): ditto.
2276 Handle nested classes.
2277 (TypeContainer::) Remove all the type visiting code, it is now
2278 replaced with the rootcontext.cs code
2280 * rootcontext.cs (GetClassBases): Added support for structs.
2282 2001-08-06 Miguel de Icaza <miguel@ximian.com>
2284 * interface.cs, statement.cs, class.cs, parameter.cs,
2285 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
2286 Drop use of TypeRefs, and use strings instead.
2288 2001-08-04 Miguel de Icaza <miguel@ximian.com>
2292 * class.cs (Struct::Struct): set the SEALED flags after
2293 checking the modifiers.
2294 (TypeContainer::TypeAttr): new property, returns the
2295 TypeAttributes for a class.
2297 * cs-parser.jay (type_list): Oops, list production was creating a
2298 new list of base types.
2300 * rootcontext.cs (StdLib): New property.
2301 (GetInterfaceTypeByName): returns an interface by type name, and
2302 encapsulates error handling here.
2303 (GetInterfaces): simplified.
2304 (ResolveTree): Encapsulated all the tree resolution here.
2305 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
2308 * driver.cs: Add support for --nostdlib, to avoid loading the
2310 (Main): Do not put tree resolution here.
2312 * rootcontext.cs: Beginning of the class resolution.
2314 2001-08-03 Miguel de Icaza <miguel@ximian.com>
2316 * rootcontext.cs: Provide better error reporting.
2318 * cs-parser.jay (interface_base): set our $$ to be interfaces.
2320 * rootcontext.cs (CreateInterface): Handle the case where there
2321 are no parent interfaces.
2323 (CloseTypes): Routine to flush types at the end.
2324 (CreateInterface): Track types.
2325 (GetInterfaces): Returns an array of Types from the list of
2328 * typemanager.c (AddUserType): Mechanism to track user types (puts
2329 the type on the global type hash, and allows us to close it at the
2332 2001-08-02 Miguel de Icaza <miguel@ximian.com>
2334 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
2335 RecordInterface instead.
2337 * cs-parser.jay: Updated to reflect changes above.
2339 * decl.cs (Definition): Keep track of the TypeBuilder type that
2340 represents this type here. Not sure we will use it in the long
2341 run, but wont hurt for now.
2343 * driver.cs: Smaller changes to accomodate the new code.
2345 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
2348 * rootcontext.cs (CreateInterface): New method, used to create
2349 the System.TypeBuilder type for interfaces.
2350 (ResolveInterfaces): new entry point to resolve the interface
2352 (CodeGen): Property, used to keep track of the code generator.
2354 2001-07-26 Miguel de Icaza <miguel@ximian.com>
2356 * cs-parser.jay: Add a second production for delegate_declaration
2359 (enum_body): Put an opt_comma here instead of putting it on
2360 enum_body or enum_member_declarations so we can handle trailing
2361 commas on enumeration members. Gets rid of a shift/reduce.
2363 (type_list): Need a COMMA in the middle.
2365 (indexer_declaration): Tell tokenizer to recognize get/set
2367 * Remove old targets.
2369 * Re-add the parser target.
2371 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2373 * cs-parser.jay: Add precendence rules for a number of operators
2374 ot reduce the number of shift/reduce conflicts in the grammar.
2376 2001-07-17 Miguel de Icaza <miguel@ximian.com>
2378 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
2381 Get rid of old crufty code.
2383 * rootcontext.cs: Use this to keep track of the parsed
2384 representation and the defined types available to the program.
2386 * gen-treedump.cs: adjust for new convention.
2388 * type.cs: Split out the type manager, and the assembly builder
2391 * typemanager.cs: the type manager will live here now.
2393 * cil-codegen.cs: And the code generator here.
2395 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
2397 * makefile: Fixed up for easy making.
2399 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2401 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
2404 (unary_expression): Expand pre_increment_expression and
2405 post_decrement_expression to reduce a shift/reduce.
2407 2001-07-11 Simon Cozens
2409 * cs-tokenizer.cs: Hex numbers should begin with a 0.
2411 Improve allow_keyword_as_indent name.
2413 2001-06-19 Miguel de Icaza <miguel@ximian.com>
2415 * Adjustments for Beta2.
2417 2001-06-13 Miguel de Icaza <miguel@ximian.com>
2419 * decl.cs: Added `Define' abstract method.
2420 (InTransit): new property, used to catch recursive definitions.
2422 * interface.cs: Implement `Define'.
2424 * modifiers.cs: Map Modifiers.constants to
2425 System.Reflection.TypeAttribute flags.
2427 * class.cs: Keep track of types and user-defined types.
2428 (BuilderInit): New method for creating an assembly
2429 (ResolveType): New function to launch the resolution process, only
2430 used by interfaces for now.
2432 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
2433 that are inserted into the name space.
2435 2001-06-08 Miguel de Icaza <miguel@ximian.com>
2437 * ARGH. I have screwed up my tree so many times due to the use of
2438 rsync rather than using CVS. Going to fix this at once.
2440 * driver.cs: Objetify driver. Load assemblies, use assemblies to
2443 2001-06-07 Miguel de Icaza <miguel@ximian.com>
2445 * Experiment successful: Use System.Type rather that our own
2448 2001-05-25 Miguel de Icaza <miguel@ximian.com>
2450 * cs-parser.jay: Removed nsAliases from here.
2452 Use new namespaces, handle `using XXX;'
2454 * namespace.cs: Reimplemented namespace handling, use a recursive
2455 definition of the class. Now we can keep track of using clauses
2456 and catch invalid using clauses.
2458 2001-05-24 Miguel de Icaza <miguel@ximian.com>
2460 * gen-treedump.cs: Adapted for all the renaming.
2462 * expression.cs (Expression): this class now has a Type property
2463 which returns an expression Type.
2465 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
2466 `Type', as this has a different meaning now in the base
2468 2001-05-22 Miguel de Icaza <miguel@ximian.com>
2470 * interface.cs, class.cs: Removed from all the sources the
2471 references to signature computation, as we can not do method
2472 signature computation during the parsing time, as we are not
2473 trying to solve at that point distinguishing:
2477 void a (NS.Blah x) {}
2480 Which depending on the context might be valid or not, as we do not
2481 know if Blah is the same thing as NS.Blah at that point.
2483 * Redid everything so the code uses TypeRefs now instead of
2484 Types. TypeRefs are just temporary type placeholders, that need
2485 to be resolved. They initially have a pointer to a string and the
2486 current scope in which they are used. This is used later by the
2487 compiler to resolve the reference to an actual Type.
2489 * DeclSpace is no longer a CIR.Type, and neither are
2490 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
2491 are all DeclSpaces, but no Types.
2493 * type.cs (TypeRefManager): This implements the TypeRef manager,
2494 which keeps track of all the types that need to be resolved after
2495 the parsing has finished.
2497 2001-05-13 Miguel de Icaza <miguel@ximian.com>
2499 * ARGH. We are going to have to store `foreach' as a class rather
2500 than resolving it, as we need to verify error 1579 after name
2501 resolution. *OR* we could keep a flag that says `This request to
2502 IEnumerator comes from a foreach statement' which we can then use
2503 to generate the error.
2505 2001-05-10 Miguel de Icaza <miguel@ximian.com>
2507 * class.cs (TypeContainer.AddMethod): we now add methods to the
2508 MethodGroup instead of the method hashtable.
2510 * expression.cs: Add MethodGroup abstraction, which gets us one
2511 step closer to the specification in the way we handle method
2514 * cs-parser.jay (primary_expression): qualified_identifier now
2515 tried to match up an identifier to a local variable reference or
2516 to a parameter reference.
2518 current_local_parameters is now a parser global variable that
2519 points to the current parameters for the block, used during name
2522 (property_declaration): Now creates an implicit `value' argument to
2525 2001-05-09 Miguel de Icaza <miguel@ximian.com>
2527 * parameter.cs: Do not use `param' arguments as part of the
2528 signature, per the spec.
2530 2001-05-08 Miguel de Icaza <miguel@ximian.com>
2532 * decl.cs: Base class for classes, structs and interfaces. This
2533 is the "Declaration Space"
2535 * cs-parser.jay: Use CheckDef for checking declaration errors
2536 instead of having one on each function.
2538 * class.cs: Factor out some code for handling error handling in
2539 accordance to the "Declarations" section in the "Basic Concepts"
2540 chapter in the ECMA C# spec.
2542 * interface.cs: Make all interface member classes derive from
2543 InterfaceMemberBase.
2545 2001-05-07 Miguel de Icaza <miguel@ximian.com>
2547 * Many things: all interfaces are parsed and generated in
2548 gen-treedump. Support for member variables, constructors,
2549 destructors, properties, constants is there.
2551 Beginning of the IL backend, but very little done, just there for
2554 2001-04-29 Miguel de Icaza <miguel@ximian.com>
2556 * cs-parser.jay: Fix labeled statement.
2558 * cs-tokenizer.cs (escape): Escape " and ' always.
2559 ref_line, ref_name: keep track of the line/filename as instructed
2560 by #line by the compiler.
2563 2001-04-27 Miguel de Icaza <miguel@ximian.com>
2565 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
2566 to match the values in System.CodeDOM.
2568 Divid renamed to Divide.
2570 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
2572 (Statements.set): remove.
2574 * System.CodeDOM/CodeCatchClause.cs: always have a valid
2577 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
2578 falseStatements always have valid values.
2580 * cs-parser.jay: Use System.CodeDOM now.
