487 information about indexer_declarator.
488 (indexer_declarator): Implement actions.

556 on Expression Classification. Now all expressions have a method
557 `Resolve' and a method `Emit'.

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

597 move from Properties to public readonly fields.
598 (Method::ParameterTypes): Returns the parameter types for the
599 function, and implements a cache that will be useful later when I
600 do error checking and the semantic analysis on the methods is

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

607 (Method::Define): Defines the type, a second pass is performed
608 later to populate the methods.

637 (Field::) use readonly public fields instead of properties also.
639 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
640 track of static constructors; If none is used, turn on
641 BeforeFieldInit in the TypeAttributes.
643 * cs-parser.jay (opt_argument_list): now the return can be null
644 for the cases where there are no arguments.
646 (constructor_declarator): If there is no implicit `base' or
647 `this', then invoke the default parent constructor.
649 * modifiers.cs (MethodAttr): New static function maps a set of

652 MethodAttr, TypeAttr to represent the various mappings where the
654 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
656 2001-08-19 Miguel de Icaza <miguel@ximian.com>
658 * parameter.cs (GetParameterInfo): Fix bug where there would be no
661 * interface.cs (PopulateIndexer): Implemented the code generator
662 for interface indexers.
664 2001-08-17 Miguel de Icaza <miguel@ximian.com>
666 * interface.cs (InterfaceMemberBase): Now we track the new status
669 (PopulateProperty): Implement property population. Woohoo! Got
670 Methods and Properties going today.
672 Removed all the properties for interfaces, and replaced them with
673 `public readonly' fields.
675 2001-08-16 Miguel de Icaza <miguel@ximian.com>
677 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
678 initialize their hashtables/arraylists only when they are needed
679 instead of doing this always.
681 * parameter.cs: Handle refs and out parameters.
683 * cs-parser.jay: Use an ArrayList to construct the arguments
684 instead of the ParameterCollection, and then cast that to a
687 * parameter.cs: Drop the use of ParameterCollection and use
688 instead arrays of Parameters.
690 (GetParameterInfo): Use the Type, not the Name when resolving
693 2001-08-13 Miguel de Icaza <miguel@ximian.com>
695 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
696 and instead use public readonly fields.
698 * class.cs: Put back walking code for type containers.
700 2001-08-11 Miguel de Icaza <miguel@ximian.com>
702 * class.cs (MakeConstant): Code to define constants.
704 * rootcontext.cs (LookupType): New function. Used to locate types
707 2001-08-08 Miguel de Icaza <miguel@ximian.com>
709 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
710 this System.Reflection code is. Kudos to Microsoft
712 * typemanager.cs: Implement a type cache and avoid loading all
713 types at boot time. Wrap in LookupType the internals. This made
714 the compiler so much faster. Wow. I rule!
716 * driver.cs: Make sure we always load mscorlib first (for
717 debugging purposes, nothing really important).
719 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
720 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
722 * rootcontext.cs: Lookup types on their namespace; Lookup types
723 on namespaces that have been imported using the `using' keyword.
725 * class.cs (TypeContainer::TypeAttr): Virtualize.
726 (Class::TypeAttr): Return attributes suitable for this bad boy.
727 (Struct::TypeAttr): ditto.
728 Handle nested classes.
729 (TypeContainer::) Remove all the type visiting code, it is now
730 replaced with the rootcontext.cs code
732 * rootcontext.cs (GetClassBases): Added support for structs.
734 2001-08-06 Miguel de Icaza <miguel@ximian.com>
736 * interface.cs, statement.cs, class.cs, parameter.cs,
737 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
738 Drop use of TypeRefs, and use strings instead.
740 2001-08-04 Miguel de Icaza <miguel@ximian.com>
744 * class.cs (Struct::Struct): set the SEALED flags after
745 checking the modifiers.
746 (TypeContainer::TypeAttr): new property, returns the
747 TypeAttributes for a class.
749 * cs-parser.jay (type_list): Oops, list production was creating a
750 new list of base types.
752 * rootcontext.cs (StdLib): New property.
753 (GetInterfaceTypeByName): returns an interface by type name, and
754 encapsulates error handling here.
755 (GetInterfaces): simplified.
756 (ResolveTree): Encapsulated all the tree resolution here.
757 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
760 * driver.cs: Add support for --nostdlib, to avoid loading the
762 (Main): Do not put tree resolution here.
764 * rootcontext.cs: Beginning of the class resolution.
766 2001-08-03 Miguel de Icaza <miguel@ximian.com>
768 * rootcontext.cs: Provide better error reporting.
770 * cs-parser.jay (interface_base): set our $$ to be interfaces.
772 * rootcontext.cs (CreateInterface): Handle the case where there
773 are no parent interfaces.
775 (CloseTypes): Routine to flush types at the end.
776 (CreateInterface): Track types.
777 (GetInterfaces): Returns an array of Types from the list of
780 * typemanager.c (AddUserType): Mechanism to track user types (puts
781 the type on the global type hash, and allows us to close it at the
784 2001-08-02 Miguel de Icaza <miguel@ximian.com>
786 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
787 RecordInterface instead.
789 * cs-parser.jay: Updated to reflect changes above.
791 * decl.cs (Definition): Keep track of the TypeBuilder type that
792 represents this type here. Not sure we will use it in the long
793 run, but wont hurt for now.
795 * driver.cs: Smaller changes to accomodate the new code.
797 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
800 * rootcontext.cs (CreateInterface): New method, used to create
801 the System.TypeBuilder type for interfaces.
802 (ResolveInterfaces): new entry point to resolve the interface
804 (CodeGen): Property, used to keep track of the code generator.
806 2001-07-26 Miguel de Icaza <miguel@ximian.com>
808 * cs-parser.jay: Add a second production for delegate_declaration
811 (enum_body): Put an opt_comma here instead of putting it on
812 enum_body or enum_member_declarations so we can handle trailing
813 commas on enumeration members. Gets rid of a shift/reduce.
815 (type_list): Need a COMMA in the middle.
817 (indexer_declaration): Tell tokenizer to recognize get/set
819 * Remove old targets.
821 * Re-add the parser target.
823 2001-07-13 Simon Cozens <simon@simon-cozens.org>
825 * cs-parser.jay: Add precendence rules for a number of operators
826 ot reduce the number of shift/reduce conflicts in the grammar.
828 2001-07-17 Miguel de Icaza <miguel@ximian.com>
830 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
833 Get rid of old crufty code.
835 * rootcontext.cs: Use this to keep track of the parsed
836 representation and the defined types available to the program.
838 * gen-treedump.cs: adjust for new convention.
840 * type.cs: Split out the type manager, and the assembly builder
843 * typemanager.cs: the type manager will live here now.
845 * cil-codegen.cs: And the code generator here.
847 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
849 * makefile: Fixed up for easy making.
851 2001-07-13 Simon Cozens <simon@simon-cozens.org>
853 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
856 (unary_expression): Expand pre_increment_expression and
857 post_decrement_expression to reduce a shift/reduce.
859 2001-07-11 Simon Cozens
861 * cs-tokenizer.cs: Hex numbers should begin with a 0.
863 Improve allow_keyword_as_indent name.
865 2001-06-19 Miguel de Icaza <miguel@ximian.com>
867 * Adjustments for Beta2.
869 2001-06-13 Miguel de Icaza <miguel@ximian.com>
871 * decl.cs: Added `Define' abstract method.
872 (InTransit): new property, used to catch recursive definitions.
874 * interface.cs: Implement `Define'.
876 * modifiers.cs: Map Modifiers.constants to
877 System.Reflection.TypeAttribute flags.
879 * class.cs: Keep track of types and user-defined types.
880 (BuilderInit): New method for creating an assembly
881 (ResolveType): New function to launch the resolution process, only
882 used by interfaces for now.
884 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
885 that are inserted into the name space.
887 2001-06-08 Miguel de Icaza <miguel@ximian.com>
889 * ARGH. I have screwed up my tree so many times due to the use of
890 rsync rather than using CVS. Going to fix this at once.
892 * driver.cs: Objetify driver. Load assemblies, use assemblies to
895 2001-06-07 Miguel de Icaza <miguel@ximian.com>
897 * Experiment successful: Use System.Type rather that our own
900 2001-05-25 Miguel de Icaza <miguel@ximian.com>
902 * cs-parser.jay: Removed nsAliases from here.
904 Use new namespaces, handle `using XXX;'
906 * namespace.cs: Reimplemented namespace handling, use a recursive
907 definition of the class. Now we can keep track of using clauses
908 and catch invalid using clauses.
910 2001-05-24 Miguel de Icaza <miguel@ximian.com>
912 * gen-treedump.cs: Adapted for all the renaming.
914 * expression.cs (Expression): this class now has a Type property
915 which returns an expression Type.
917 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
918 `Type', as this has a different meaning now in the base
920 2001-05-22 Miguel de Icaza <miguel@ximian.com>
922 * interface.cs, class.cs: Removed from all the sources the
923 references to signature computation, as we can not do method
924 signature computation during the parsing time, as we are not
925 trying to solve at that point distinguishing:
929 void a (NS.Blah x) {}
932 Which depending on the context might be valid or not, as we do not
933 know if Blah is the same thing as NS.Blah at that point.
935 * Redid everything so the code uses TypeRefs now instead of
936 Types. TypeRefs are just temporary type placeholders, that need
937 to be resolved. They initially have a pointer to a string and the
938 current scope in which they are used. This is used later by the
939 compiler to resolve the reference to an actual Type.
941 * DeclSpace is no longer a CIR.Type, and neither are
942 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
943 are all DeclSpaces, but no Types.
945 * type.cs (TypeRefManager): This implements the TypeRef manager,
946 which keeps track of all the types that need to be resolved after
947 the parsing has finished.
949 2001-05-13 Miguel de Icaza <miguel@ximian.com>
951 * ARGH. We are going to have to store `foreach' as a class rather
952 than resolving it, as we need to verify error 1579 after name
953 resolution. *OR* we could keep a flag that says `This request to
954 IEnumerator comes from a foreach statement' which we can then use
955 to generate the error.
957 2001-05-10 Miguel de Icaza <miguel@ximian.com>
959 * class.cs (TypeContainer.AddMethod): we now add methods to the
960 MethodGroup instead of the method hashtable.
962 * expression.cs: Add MethodGroup abstraction, which gets us one
963 step closer to the specification in the way we handle method
966 * cs-parser.jay (primary_expression): qualified_identifier now
967 tried to match up an identifier to a local variable reference or
968 to a parameter reference.
970 current_local_parameters is now a parser global variable that
971 points to the current parameters for the block, used during name
974 (property_declaration): Now creates an implicit `value' argument to
977 2001-05-09 Miguel de Icaza <miguel@ximian.com>
979 * parameter.cs: Do not use `param' arguments as part of the
980 signature, per the spec.
982 2001-05-08 Miguel de Icaza <miguel@ximian.com>
984 * decl.cs: Base class for classes, structs and interfaces. This
985 is the "Declaration Space"
987 * cs-parser.jay: Use CheckDef for checking declaration errors
988 instead of having one on each function.
990 * class.cs: Factor out some code for handling error handling in
991 accordance to the "Declarations" section in the "Basic Concepts"
992 chapter in the ECMA C# spec.
994 * interface.cs: Make all interface member classes derive from
997 2001-05-07 Miguel de Icaza <miguel@ximian.com>
999 * Many things: all interfaces are parsed and generated in
1000 gen-treedump. Support for member variables, constructors,
1001 destructors, properties, constants is there.
1003 Beginning of the IL backend, but very little done, just there for
1006 2001-04-29 Miguel de Icaza <miguel@ximian.com>
1008 * cs-parser.jay: Fix labeled statement.
1010 * cs-tokenizer.cs (escape): Escape " and ' always.
1011 ref_line, ref_name: keep track of the line/filename as instructed
1012 by #line by the compiler.
1015 2001-04-27 Miguel de Icaza <miguel@ximian.com>
1017 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
1018 to match the values in System.CodeDOM.
1020 Divid renamed to Divide.
1022 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
1024 (Statements.set): remove.
1026 * System.CodeDOM/CodeCatchClause.cs: always have a valid
1029 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
1030 falseStatements always have valid values.
1032 * cs-parser.jay: Use System.CodeDOM now.
