1 2001-09-13 Miguel de Icaza <miguel@ximian.com>
3 * class.cs: Allocate a MemberInfo of the correct size, as the code
4 elsewhere depends on the test to reflect the correct contents.
6 (Method::) Keep track of parameters, due to System.Reflection holes
8 (TypeContainer::Populate): Keep track of MethodBuilders to Method
11 (TypeContainer::FindMembers): Use ArrayList and then copy an array
12 of the exact size and return that.
14 (Class::LookupMethodByBuilder): New function that maps
15 MethodBuilders to its methods. Required to locate the information
16 on methods because System.Reflection bit us again.
18 * support.cs: New file, contains an interface ParameterData and
19 two implementations: ReflectionParameters and InternalParameters
20 used to access Parameter information. We will need to grow this
23 * expression.cs (Invocation::GetParameterData): implement a cache

183 on the name without any prefixes of namespace names etc. This is because we
184 already might have something already fully qualified like
185 'System.Console.WriteLine'

515 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
516 Hooray, try and catch statements parse fine !
518 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
520 * statement.cs (Block::GetVariableType): Fix logic to extract the type

538 information about indexer_declarator.
539 (indexer_declarator): Implement actions.

573 (array_type): Modify to actually return the complete type string
574 instead of ignoring the rank_specifiers.
575 (expression_list): Implement to collect the expressions

603 defined types (this distinction will be important later while
604 compiling corlib.dll)

607 on Expression Classification. Now all expressions have a method
608 `Resolve' and a method `Emit'.

611 generation from working. Also add some temporary debugging
614 2001-08-24 Miguel de Icaza <miguel@ximian.com>
616 * codegen.cs: Lots of code generation pieces. This is only the
617 beginning, will continue tomorrow with more touches of polish. We
618 handle the fundamentals of if, while, do, for, return. Others are

621 * gen-treedump.cs: Bug fix, use s.Increment here instead of
624 * codegen.cs (EmitContext): New struct, used during code
625 emission to keep a context. Most of the code generation will be

647 (Method::): Applied the same simplification that I did before, and
648 move from Properties to public readonly fields.
649 (Method::ParameterTypes): Returns the parameter types for the
650 function, and implements a cache that will be useful later when I
651 do error checking and the semantic analysis on the methods is
653 (Constructor::GetCallingConvention): Renamed from CallingConvetion
654 and made a method, optional argument tells whether this is a class
655 or a structure to apply the `has-this' bit.
656 (Method::GetCallingConvention): Implement, returns the calling
658 (Method::Define): Defines the type, a second pass is performed
659 later to populate the methods.
661 (Constructor::ParameterTypes): implement a cache similar to the
662 one on Method::ParameterTypes, useful later when we do semantic
665 (TypeContainer::EmitMethod): New method. Emits methods.
667 * expression.cs: Removed MethodGroup class from here.
669 * parameter.cs (Parameters::GetCallingConvention): new method.
671 2001-08-21 Miguel de Icaza <miguel@ximian.com>
673 * class.cs (TypeContainer::Populate): Drop RootContext from the
676 (Constructor::CallingConvention): Returns the calling convention.
677 (Constructor::ParameterTypes): Returns the constructor parameter
680 (TypeContainer::AddConstructor): Keep track of default constructor
681 and the default static constructor.
683 (Constructor::) Another class that starts using `public readonly'
684 instead of properties.
686 (Constructor::IsDefault): Whether this is a default constructor.
688 (Field::) use readonly public fields instead of properties also.
690 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
691 track of static constructors; If none is used, turn on
692 BeforeFieldInit in the TypeAttributes.
694 * cs-parser.jay (opt_argument_list): now the return can be null
695 for the cases where there are no arguments.
697 (constructor_declarator): If there is no implicit `base' or
698 `this', then invoke the default parent constructor.
700 * modifiers.cs (MethodAttr): New static function maps a set of
701 modifiers flags into a MethodAttributes enum
702 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
703 MethodAttr, TypeAttr to represent the various mappings where the
705 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
707 2001-08-19 Miguel de Icaza <miguel@ximian.com>
709 * parameter.cs (GetParameterInfo): Fix bug where there would be no
712 * interface.cs (PopulateIndexer): Implemented the code generator
713 for interface indexers.
715 2001-08-17 Miguel de Icaza <miguel@ximian.com>
717 * interface.cs (InterfaceMemberBase): Now we track the new status
720 (PopulateProperty): Implement property population. Woohoo! Got
721 Methods and Properties going today.
723 Removed all the properties for interfaces, and replaced them with
724 `public readonly' fields.
726 2001-08-16 Miguel de Icaza <miguel@ximian.com>
728 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
729 initialize their hashtables/arraylists only when they are needed
730 instead of doing this always.
732 * parameter.cs: Handle refs and out parameters.
734 * cs-parser.jay: Use an ArrayList to construct the arguments
735 instead of the ParameterCollection, and then cast that to a
738 * parameter.cs: Drop the use of ParameterCollection and use
739 instead arrays of Parameters.
741 (GetParameterInfo): Use the Type, not the Name when resolving
744 2001-08-13 Miguel de Icaza <miguel@ximian.com>
746 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
747 and instead use public readonly fields.
749 * class.cs: Put back walking code for type containers.
751 2001-08-11 Miguel de Icaza <miguel@ximian.com>
753 * class.cs (MakeConstant): Code to define constants.
755 * rootcontext.cs (LookupType): New function. Used to locate types
758 2001-08-08 Miguel de Icaza <miguel@ximian.com>
760 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
761 this System.Reflection code is. Kudos to Microsoft
763 * typemanager.cs: Implement a type cache and avoid loading all
764 types at boot time. Wrap in LookupType the internals. This made
765 the compiler so much faster. Wow. I rule!
767 * driver.cs: Make sure we always load mscorlib first (for
768 debugging purposes, nothing really important).
770 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
771 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
773 * rootcontext.cs: Lookup types on their namespace; Lookup types
774 on namespaces that have been imported using the `using' keyword.
776 * class.cs (TypeContainer::TypeAttr): Virtualize.
777 (Class::TypeAttr): Return attributes suitable for this bad boy.
778 (Struct::TypeAttr): ditto.
779 Handle nested classes.
780 (TypeContainer::) Remove all the type visiting code, it is now
781 replaced with the rootcontext.cs code
783 * rootcontext.cs (GetClassBases): Added support for structs.
785 2001-08-06 Miguel de Icaza <miguel@ximian.com>
787 * interface.cs, statement.cs, class.cs, parameter.cs,
788 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
789 Drop use of TypeRefs, and use strings instead.
791 2001-08-04 Miguel de Icaza <miguel@ximian.com>
795 * class.cs (Struct::Struct): set the SEALED flags after
796 checking the modifiers.
797 (TypeContainer::TypeAttr): new property, returns the
798 TypeAttributes for a class.
800 * cs-parser.jay (type_list): Oops, list production was creating a
801 new list of base types.
803 * rootcontext.cs (StdLib): New property.
804 (GetInterfaceTypeByName): returns an interface by type name, and
805 encapsulates error handling here.
806 (GetInterfaces): simplified.
807 (ResolveTree): Encapsulated all the tree resolution here.
808 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
811 * driver.cs: Add support for --nostdlib, to avoid loading the
813 (Main): Do not put tree resolution here.
815 * rootcontext.cs: Beginning of the class resolution.
817 2001-08-03 Miguel de Icaza <miguel@ximian.com>
819 * rootcontext.cs: Provide better error reporting.
821 * cs-parser.jay (interface_base): set our $$ to be interfaces.
823 * rootcontext.cs (CreateInterface): Handle the case where there
824 are no parent interfaces.
826 (CloseTypes): Routine to flush types at the end.
827 (CreateInterface): Track types.
828 (GetInterfaces): Returns an array of Types from the list of
831 * typemanager.c (AddUserType): Mechanism to track user types (puts
832 the type on the global type hash, and allows us to close it at the
835 2001-08-02 Miguel de Icaza <miguel@ximian.com>
837 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
838 RecordInterface instead.
840 * cs-parser.jay: Updated to reflect changes above.
842 * decl.cs (Definition): Keep track of the TypeBuilder type that
843 represents this type here. Not sure we will use it in the long
844 run, but wont hurt for now.
846 * driver.cs: Smaller changes to accomodate the new code.
848 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
851 * rootcontext.cs (CreateInterface): New method, used to create
852 the System.TypeBuilder type for interfaces.
853 (ResolveInterfaces): new entry point to resolve the interface
855 (CodeGen): Property, used to keep track of the code generator.
857 2001-07-26 Miguel de Icaza <miguel@ximian.com>
859 * cs-parser.jay: Add a second production for delegate_declaration
862 (enum_body): Put an opt_comma here instead of putting it on
863 enum_body or enum_member_declarations so we can handle trailing
864 commas on enumeration members. Gets rid of a shift/reduce.
866 (type_list): Need a COMMA in the middle.
868 (indexer_declaration): Tell tokenizer to recognize get/set
870 * Remove old targets.
872 * Re-add the parser target.
874 2001-07-13 Simon Cozens <simon@simon-cozens.org>
876 * cs-parser.jay: Add precendence rules for a number of operators
877 ot reduce the number of shift/reduce conflicts in the grammar.
879 2001-07-17 Miguel de Icaza <miguel@ximian.com>
881 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
884 Get rid of old crufty code.
886 * rootcontext.cs: Use this to keep track of the parsed
887 representation and the defined types available to the program.
889 * gen-treedump.cs: adjust for new convention.
891 * type.cs: Split out the type manager, and the assembly builder
894 * typemanager.cs: the type manager will live here now.
896 * cil-codegen.cs: And the code generator here.
898 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
900 * makefile: Fixed up for easy making.
902 2001-07-13 Simon Cozens <simon@simon-cozens.org>
904 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
907 (unary_expression): Expand pre_increment_expression and
908 post_decrement_expression to reduce a shift/reduce.
910 2001-07-11 Simon Cozens
912 * cs-tokenizer.cs: Hex numbers should begin with a 0.
914 Improve allow_keyword_as_indent name.
916 2001-06-19 Miguel de Icaza <miguel@ximian.com>
918 * Adjustments for Beta2.
920 2001-06-13 Miguel de Icaza <miguel@ximian.com>
922 * decl.cs: Added `Define' abstract method.
923 (InTransit): new property, used to catch recursive definitions.
925 * interface.cs: Implement `Define'.
927 * modifiers.cs: Map Modifiers.constants to
928 System.Reflection.TypeAttribute flags.
930 * class.cs: Keep track of types and user-defined types.
931 (BuilderInit): New method for creating an assembly
932 (ResolveType): New function to launch the resolution process, only
933 used by interfaces for now.
935 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
936 that are inserted into the name space.
938 2001-06-08 Miguel de Icaza <miguel@ximian.com>
940 * ARGH. I have screwed up my tree so many times due to the use of
941 rsync rather than using CVS. Going to fix this at once.
943 * driver.cs: Objetify driver. Load assemblies, use assemblies to
946 2001-06-07 Miguel de Icaza <miguel@ximian.com>
948 * Experiment successful: Use System.Type rather that our own
951 2001-05-25 Miguel de Icaza <miguel@ximian.com>
953 * cs-parser.jay: Removed nsAliases from here.
955 Use new namespaces, handle `using XXX;'
957 * namespace.cs: Reimplemented namespace handling, use a recursive
958 definition of the class. Now we can keep track of using clauses
959 and catch invalid using clauses.
961 2001-05-24 Miguel de Icaza <miguel@ximian.com>
963 * gen-treedump.cs: Adapted for all the renaming.
965 * expression.cs (Expression): this class now has a Type property
966 which returns an expression Type.
968 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
969 `Type', as this has a different meaning now in the base
971 2001-05-22 Miguel de Icaza <miguel@ximian.com>
973 * interface.cs, class.cs: Removed from all the sources the
974 references to signature computation, as we can not do method
975 signature computation during the parsing time, as we are not
976 trying to solve at that point distinguishing:
980 void a (NS.Blah x) {}
983 Which depending on the context might be valid or not, as we do not
984 know if Blah is the same thing as NS.Blah at that point.
986 * Redid everything so the code uses TypeRefs now instead of
987 Types. TypeRefs are just temporary type placeholders, that need
988 to be resolved. They initially have a pointer to a string and the
989 current scope in which they are used. This is used later by the
990 compiler to resolve the reference to an actual Type.
992 * DeclSpace is no longer a CIR.Type, and neither are
993 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
994 are all DeclSpaces, but no Types.
996 * type.cs (TypeRefManager): This implements the TypeRef manager,
997 which keeps track of all the types that need to be resolved after
998 the parsing has finished.
1000 2001-05-13 Miguel de Icaza <miguel@ximian.com>
1002 * ARGH. We are going to have to store `foreach' as a class rather
1003 than resolving it, as we need to verify error 1579 after name
1004 resolution. *OR* we could keep a flag that says `This request to
1005 IEnumerator comes from a foreach statement' which we can then use
1006 to generate the error.
1008 2001-05-10 Miguel de Icaza <miguel@ximian.com>
1010 * class.cs (TypeContainer.AddMethod): we now add methods to the
1011 MethodGroup instead of the method hashtable.
1013 * expression.cs: Add MethodGroup abstraction, which gets us one
1014 step closer to the specification in the way we handle method
1017 * cs-parser.jay (primary_expression): qualified_identifier now
1018 tried to match up an identifier to a local variable reference or
1019 to a parameter reference.
1021 current_local_parameters is now a parser global variable that
1022 points to the current parameters for the block, used during name
1025 (property_declaration): Now creates an implicit `value' argument to
1028 2001-05-09 Miguel de Icaza <miguel@ximian.com>
1030 * parameter.cs: Do not use `param' arguments as part of the
1031 signature, per the spec.
1033 2001-05-08 Miguel de Icaza <miguel@ximian.com>
1035 * decl.cs: Base class for classes, structs and interfaces. This
1036 is the "Declaration Space"
1038 * cs-parser.jay: Use CheckDef for checking declaration errors
1039 instead of having one on each function.
1041 * class.cs: Factor out some code for handling error handling in
1042 accordance to the "Declarations" section in the "Basic Concepts"
1043 chapter in the ECMA C# spec.
1045 * interface.cs: Make all interface member classes derive from
1046 InterfaceMemberBase.
1048 2001-05-07 Miguel de Icaza <miguel@ximian.com>
1050 * Many things: all interfaces are parsed and generated in
1051 gen-treedump. Support for member variables, constructors,
1052 destructors, properties, constants is there.
1054 Beginning of the IL backend, but very little done, just there for
1057 2001-04-29 Miguel de Icaza <miguel@ximian.com>
1059 * cs-parser.jay: Fix labeled statement.
1061 * cs-tokenizer.cs (escape): Escape " and ' always.
1062 ref_line, ref_name: keep track of the line/filename as instructed
1063 by #line by the compiler.
1066 2001-04-27 Miguel de Icaza <miguel@ximian.com>
1068 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
1069 to match the values in System.CodeDOM.
1071 Divid renamed to Divide.
1073 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
1075 (Statements.set): remove.
1077 * System.CodeDOM/CodeCatchClause.cs: always have a valid
1080 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
1081 falseStatements always have valid values.
1083 * cs-parser.jay: Use System.CodeDOM now.
