3 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
4 FamORAssem, not FamANDAssem.
6 2001-09-14 Miguel de Icaza <miguel@ximian.com>
8 * driver.cs: Added --parse option that only parses its input files
11 * class.cs: Reveted lsat change from Ravi to IsTopLevel. That is
12 incorrect. IsTopLevel is not used to tell whether an object is
13 root_types or not (that can be achieved by testing this ==
14 root_types). But to see if this is a top-level *class* (not
15 necessarly our "toplevel" container).
17 2001-09-14 Ravi Pratap <ravi@ximian.com>
19 * enum.cs (Enum::Define): Modify to call the Lookup method on the
20 parent instead of a direct call to GetType.
22 2001-09-14 Ravi Pratap <ravi@ximian.com>

28 object so that we can determine if we are top-level or not.
30 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the

38 (TypeContainer::HaveStaticConstructor): New property to provide access
39 to precisely that info.
41 * modifiers.cs (MethodAttr): Re-write.
42 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
44 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
45 of top-level types as claimed.
47 2001-09-13 Miguel de Icaza <miguel@ximian.com>
49 * expression.cs (MemberLookup): Fruitless attempt to lookup
50 constructors. Maybe I need to emit default constructors? That
51 might be it (currently .NET emits this for me automatically).
52 (Invocation::OverloadResolve): Cope with Arguments == null.
53 (Invocation::EmitArguments): new function, shared by the new

87 (Binary::ResolveOperator): Set the return type to boolean for
88 comparission operators
90 * typemanager.cs: Remove debugging print code.
92 (Invocation::Resolve): resolve type.
94 * class.cs: Allocate a MemberInfo of the correct size, as the code
95 elsewhere depends on the test to reflect the correct contents.
97 (Method::) Keep track of parameters, due to System.Reflection holes
99 (TypeContainer::Populate): Keep track of MethodBuilders to Method
102 (TypeContainer::FindMembers): Use ArrayList and then copy an array
103 of the exact size and return that.
105 (Class::LookupMethodByBuilder): New function that maps
106 MethodBuilders to its methods. Required to locate the information
107 on methods because System.Reflection bit us again.
109 * support.cs: New file, contains an interface ParameterData and
110 two implementations: ReflectionParameters and InternalParameters
111 used to access Parameter information. We will need to grow this
114 * expression.cs (Invocation::GetParameterData): implement a cache
115 and a wrapper around the ParameterData creation for methods.
116 (Invocation::OverloadResolve): Use new code.
118 2001-09-13 Ravi Pratap <ravi@ximian.com>

129 initialized with the full type once it is resolved.
131 2001-09-12 Miguel de Icaza <miguel@ximian.com>
133 * parameter.cs (GetParameterInfo): Use a type cache to compute
134 things only once, and to reuse this information
136 * expression.cs (LocalVariableReference::Emit): Implement.
137 (OpcodeCast::Emit): fix.
139 (ParameterReference::Resolve): Implement.
140 (ParameterReference::Emit): Implement.
142 * cs-parser.jay: Fix bug introduced by Ravi, variable initializers

178 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
179 typecontainer objects as we need to get at them.
180 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

186 of just a Report object.
188 2001-09-11 Ravi Pratap <ravi@ximian.com>

202 * class.cs (Indexer::Define): Fix for loop iteration condition to be just <
204 (Operator::Define): Re-write logic to get types by using the LookupType method

221 * class.cs (Event::Define): Make the prefixes of the accessor methods
224 * genericparser.cs (GenericParser::error): Overloaded method to handle the case
225 of the location being passed in too. Ideally, this should go later since all
226 error reporting should be done through the Report object.
228 * class.cs (TypeContainer.Indexers): New property to access the list of indexers.
229 (Populate): Iterate thru the indexers we have and define them too.
230 (Indexer.GetMethodBuilder, .SetMethodBuilder): New members to hold the method builders

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

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

432 accessability of elements of it.

435 Expressions that creates a fully initialized Expression based on
436 a MemberInfo that is one of Eventinfo, FieldINfo, PropertyInfo or

604 general catch clauses by being a little smart ;-)
606 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
607 Hooray, try and catch statements parse fine !
609 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
611 * statement.cs (Block::GetVariableType): Fix logic to extract the type
612 string from the hashtable of variables.

629 information about indexer_declarator.
630 (indexer_declarator): Implement actions.

661 (rank_specifiers): Update accordingly. Basically do the same
662 thing - instead, collect the brackets here.
663 (opt_rank_sepcifiers): Modify accordingly.
664 (array_type): Modify to actually return the complete type string
665 instead of ignoring the rank_specifiers.
666 (expression_list): Implement to collect the expressions
667 (variable_initializer): Implement. We make it a list of expressions
668 essentially so that we can handle the array_initializer case neatly too.
669 (variable_initializer_list): Implement.
670 (array_initializer): Make it a list of variable_initializers
671 (opt_array_initializer): Modify accordingly.
673 * expression.cs (New::NType): Add enumeration to help us
674 keep track of whether we have an object/delegate creation
675 or an array creation.
676 (New:NewType, New::Rank, New::Indices, New::Initializers): New
677 members to hold data about array creation.
678 (New:New): Modify to update NewType
679 (New:New): New Overloaded contructor for the array creation
682 * cs-parser.jay (array_creation_expression): Implement to call
683 the overloaded New constructor.

688 constructors instead of returning null.
690 2001-08-26 Miguel de Icaza <miguel@ximian.com>
692 * typemanager.cs (InitCoreTypes): Initialize the various core
693 types after we have populated the type manager with the user
694 defined types (this distinction will be important later while
695 compiling corlib.dll)
697 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
698 on Expression Classification. Now all expressions have a method
699 `Resolve' and a method `Emit'.
701 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
702 generation from working. Also add some temporary debugging
705 2001-08-24 Miguel de Icaza <miguel@ximian.com>
707 * codegen.cs: Lots of code generation pieces. This is only the
708 beginning, will continue tomorrow with more touches of polish. We
709 handle the fundamentals of if, while, do, for, return. Others are
710 trickier and I need to start working on invocations soon.
712 * gen-treedump.cs: Bug fix, use s.Increment here instead of
715 * codegen.cs (EmitContext): New struct, used during code
716 emission to keep a context. Most of the code generation will be
719 * cs-parser.jay: Add embedded blocks to the list of statements of
720 this block. So code generation proceeds in a top down fashion.
722 2001-08-23 Miguel de Icaza <miguel@ximian.com>
724 * statement.cs: Add support for multiple child blocks.
726 2001-08-22 Miguel de Icaza <miguel@ximian.com>
728 * codegen.cs (EmitCode): New function, will emit the code for a
729 Block of code given a TypeContainer and its ILGenerator.
731 * statement.cs (Block): Standard public readonly optimization.
732 (Block::Block constructors): Link children.
733 (Block::Child): Child Linker.
734 (Block::EmitVariables): Emits IL variable declarations.
736 * class.cs: Drop support for MethodGroups here, delay until
738 (Method::): Applied the same simplification that I did before, and
739 move from Properties to public readonly fields.
740 (Method::ParameterTypes): Returns the parameter types for the
741 function, and implements a cache that will be useful later when I
742 do error checking and the semantic analysis on the methods is
744 (Constructor::GetCallingConvention): Renamed from CallingConvetion
745 and made a method, optional argument tells whether this is a class
746 or a structure to apply the `has-this' bit.
747 (Method::GetCallingConvention): Implement, returns the calling
749 (Method::Define): Defines the type, a second pass is performed
750 later to populate the methods.
752 (Constructor::ParameterTypes): implement a cache similar to the
753 one on Method::ParameterTypes, useful later when we do semantic
756 (TypeContainer::EmitMethod): New method. Emits methods.
758 * expression.cs: Removed MethodGroup class from here.
760 * parameter.cs (Parameters::GetCallingConvention): new method.
762 2001-08-21 Miguel de Icaza <miguel@ximian.com>
764 * class.cs (TypeContainer::Populate): Drop RootContext from the
767 (Constructor::CallingConvention): Returns the calling convention.
768 (Constructor::ParameterTypes): Returns the constructor parameter
771 (TypeContainer::AddConstructor): Keep track of default constructor
772 and the default static constructor.
774 (Constructor::) Another class that starts using `public readonly'
775 instead of properties.
777 (Constructor::IsDefault): Whether this is a default constructor.
779 (Field::) use readonly public fields instead of properties also.
781 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
782 track of static constructors; If none is used, turn on
783 BeforeFieldInit in the TypeAttributes.
785 * cs-parser.jay (opt_argument_list): now the return can be null
786 for the cases where there are no arguments.
788 (constructor_declarator): If there is no implicit `base' or
789 `this', then invoke the default parent constructor.
791 * modifiers.cs (MethodAttr): New static function maps a set of
792 modifiers flags into a MethodAttributes enum
793 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
794 MethodAttr, TypeAttr to represent the various mappings where the
796 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
798 2001-08-19 Miguel de Icaza <miguel@ximian.com>
800 * parameter.cs (GetParameterInfo): Fix bug where there would be no
803 * interface.cs (PopulateIndexer): Implemented the code generator
804 for interface indexers.
806 2001-08-17 Miguel de Icaza <miguel@ximian.com>
808 * interface.cs (InterfaceMemberBase): Now we track the new status
811 (PopulateProperty): Implement property population. Woohoo! Got
812 Methods and Properties going today.
814 Removed all the properties for interfaces, and replaced them with
815 `public readonly' fields.
817 2001-08-16 Miguel de Icaza <miguel@ximian.com>
819 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
820 initialize their hashtables/arraylists only when they are needed
821 instead of doing this always.
823 * parameter.cs: Handle refs and out parameters.
825 * cs-parser.jay: Use an ArrayList to construct the arguments
826 instead of the ParameterCollection, and then cast that to a
829 * parameter.cs: Drop the use of ParameterCollection and use
830 instead arrays of Parameters.
832 (GetParameterInfo): Use the Type, not the Name when resolving
835 2001-08-13 Miguel de Icaza <miguel@ximian.com>
837 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
838 and instead use public readonly fields.
840 * class.cs: Put back walking code for type containers.
842 2001-08-11 Miguel de Icaza <miguel@ximian.com>
844 * class.cs (MakeConstant): Code to define constants.
846 * rootcontext.cs (LookupType): New function. Used to locate types
849 2001-08-08 Miguel de Icaza <miguel@ximian.com>
851 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
852 this System.Reflection code is. Kudos to Microsoft
854 * typemanager.cs: Implement a type cache and avoid loading all
855 types at boot time. Wrap in LookupType the internals. This made
856 the compiler so much faster. Wow. I rule!
858 * driver.cs: Make sure we always load mscorlib first (for
859 debugging purposes, nothing really important).
861 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
862 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
864 * rootcontext.cs: Lookup types on their namespace; Lookup types
865 on namespaces that have been imported using the `using' keyword.
867 * class.cs (TypeContainer::TypeAttr): Virtualize.
868 (Class::TypeAttr): Return attributes suitable for this bad boy.
869 (Struct::TypeAttr): ditto.
870 Handle nested classes.
871 (TypeContainer::) Remove all the type visiting code, it is now
872 replaced with the rootcontext.cs code
874 * rootcontext.cs (GetClassBases): Added support for structs.
876 2001-08-06 Miguel de Icaza <miguel@ximian.com>
878 * interface.cs, statement.cs, class.cs, parameter.cs,
879 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
880 Drop use of TypeRefs, and use strings instead.
882 2001-08-04 Miguel de Icaza <miguel@ximian.com>
886 * class.cs (Struct::Struct): set the SEALED flags after
887 checking the modifiers.
888 (TypeContainer::TypeAttr): new property, returns the
889 TypeAttributes for a class.
891 * cs-parser.jay (type_list): Oops, list production was creating a
892 new list of base types.
894 * rootcontext.cs (StdLib): New property.
895 (GetInterfaceTypeByName): returns an interface by type name, and
896 encapsulates error handling here.
897 (GetInterfaces): simplified.
898 (ResolveTree): Encapsulated all the tree resolution here.
899 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
902 * driver.cs: Add support for --nostdlib, to avoid loading the
904 (Main): Do not put tree resolution here.
906 * rootcontext.cs: Beginning of the class resolution.
908 2001-08-03 Miguel de Icaza <miguel@ximian.com>
910 * rootcontext.cs: Provide better error reporting.
912 * cs-parser.jay (interface_base): set our $$ to be interfaces.
914 * rootcontext.cs (CreateInterface): Handle the case where there
915 are no parent interfaces.
917 (CloseTypes): Routine to flush types at the end.
918 (CreateInterface): Track types.
919 (GetInterfaces): Returns an array of Types from the list of
922 * typemanager.c (AddUserType): Mechanism to track user types (puts
923 the type on the global type hash, and allows us to close it at the
926 2001-08-02 Miguel de Icaza <miguel@ximian.com>
928 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
929 RecordInterface instead.
931 * cs-parser.jay: Updated to reflect changes above.
933 * decl.cs (Definition): Keep track of the TypeBuilder type that
934 represents this type here. Not sure we will use it in the long
935 run, but wont hurt for now.
937 * driver.cs: Smaller changes to accomodate the new code.
939 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
942 * rootcontext.cs (CreateInterface): New method, used to create
943 the System.TypeBuilder type for interfaces.
944 (ResolveInterfaces): new entry point to resolve the interface
946 (CodeGen): Property, used to keep track of the code generator.
948 2001-07-26 Miguel de Icaza <miguel@ximian.com>
950 * cs-parser.jay: Add a second production for delegate_declaration
953 (enum_body): Put an opt_comma here instead of putting it on
954 enum_body or enum_member_declarations so we can handle trailing
955 commas on enumeration members. Gets rid of a shift/reduce.
957 (type_list): Need a COMMA in the middle.
959 (indexer_declaration): Tell tokenizer to recognize get/set
961 * Remove old targets.
963 * Re-add the parser target.
965 2001-07-13 Simon Cozens <simon@simon-cozens.org>
967 * cs-parser.jay: Add precendence rules for a number of operators
968 ot reduce the number of shift/reduce conflicts in the grammar.
970 2001-07-17 Miguel de Icaza <miguel@ximian.com>
972 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
975 Get rid of old crufty code.
977 * rootcontext.cs: Use this to keep track of the parsed
978 representation and the defined types available to the program.
980 * gen-treedump.cs: adjust for new convention.
982 * type.cs: Split out the type manager, and the assembly builder
985 * typemanager.cs: the type manager will live here now.
987 * cil-codegen.cs: And the code generator here.
989 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
991 * makefile: Fixed up for easy making.
993 2001-07-13 Simon Cozens <simon@simon-cozens.org>
995 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
998 (unary_expression): Expand pre_increment_expression and
999 post_decrement_expression to reduce a shift/reduce.
1001 2001-07-11 Simon Cozens
1003 * cs-tokenizer.cs: Hex numbers should begin with a 0.
1005 Improve allow_keyword_as_indent name.
1007 2001-06-19 Miguel de Icaza <miguel@ximian.com>
1009 * Adjustments for Beta2.
1011 2001-06-13 Miguel de Icaza <miguel@ximian.com>
1013 * decl.cs: Added `Define' abstract method.
1014 (InTransit): new property, used to catch recursive definitions.
1016 * interface.cs: Implement `Define'.
1018 * modifiers.cs: Map Modifiers.constants to
1019 System.Reflection.TypeAttribute flags.
1021 * class.cs: Keep track of types and user-defined types.
1022 (BuilderInit): New method for creating an assembly
1023 (ResolveType): New function to launch the resolution process, only
1024 used by interfaces for now.
1026 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
1027 that are inserted into the name space.
1029 2001-06-08 Miguel de Icaza <miguel@ximian.com>
1031 * ARGH. I have screwed up my tree so many times due to the use of
1032 rsync rather than using CVS. Going to fix this at once.
1034 * driver.cs: Objetify driver. Load assemblies, use assemblies to
1037 2001-06-07 Miguel de Icaza <miguel@ximian.com>
1039 * Experiment successful: Use System.Type rather that our own
1042 2001-05-25 Miguel de Icaza <miguel@ximian.com>
1044 * cs-parser.jay: Removed nsAliases from here.
1046 Use new namespaces, handle `using XXX;'
1048 * namespace.cs: Reimplemented namespace handling, use a recursive
1049 definition of the class. Now we can keep track of using clauses
1050 and catch invalid using clauses.
1052 2001-05-24 Miguel de Icaza <miguel@ximian.com>
1054 * gen-treedump.cs: Adapted for all the renaming.
1056 * expression.cs (Expression): this class now has a Type property
1057 which returns an expression Type.
1059 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
1060 `Type', as this has a different meaning now in the base
1062 2001-05-22 Miguel de Icaza <miguel@ximian.com>
1064 * interface.cs, class.cs: Removed from all the sources the
1065 references to signature computation, as we can not do method
1066 signature computation during the parsing time, as we are not
1067 trying to solve at that point distinguishing:
1071 void a (NS.Blah x) {}
1074 Which depending on the context might be valid or not, as we do not
1075 know if Blah is the same thing as NS.Blah at that point.
1077 * Redid everything so the code uses TypeRefs now instead of
1078 Types. TypeRefs are just temporary type placeholders, that need
1079 to be resolved. They initially have a pointer to a string and the
1080 current scope in which they are used. This is used later by the
1081 compiler to resolve the reference to an actual Type.
1083 * DeclSpace is no longer a CIR.Type, and neither are
1084 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
1085 are all DeclSpaces, but no Types.
1087 * type.cs (TypeRefManager): This implements the TypeRef manager,
1088 which keeps track of all the types that need to be resolved after
1089 the parsing has finished.
1091 2001-05-13 Miguel de Icaza <miguel@ximian.com>
1093 * ARGH. We are going to have to store `foreach' as a class rather
1094 than resolving it, as we need to verify error 1579 after name
1095 resolution. *OR* we could keep a flag that says `This request to
1096 IEnumerator comes from a foreach statement' which we can then use
1097 to generate the error.
1099 2001-05-10 Miguel de Icaza <miguel@ximian.com>
1101 * class.cs (TypeContainer.AddMethod): we now add methods to the
1102 MethodGroup instead of the method hashtable.
1104 * expression.cs: Add MethodGroup abstraction, which gets us one
1105 step closer to the specification in the way we handle method
1108 * cs-parser.jay (primary_expression): qualified_identifier now
1109 tried to match up an identifier to a local variable reference or
1110 to a parameter reference.
1112 current_local_parameters is now a parser global variable that
1113 points to the current parameters for the block, used during name
1116 (property_declaration): Now creates an implicit `value' argument to
1119 2001-05-09 Miguel de Icaza <miguel@ximian.com>
1121 * parameter.cs: Do not use `param' arguments as part of the
1122 signature, per the spec.
1124 2001-05-08 Miguel de Icaza <miguel@ximian.com>
1126 * decl.cs: Base class for classes, structs and interfaces. This
1127 is the "Declaration Space"
1129 * cs-parser.jay: Use CheckDef for checking declaration errors
1130 instead of having one on each function.
1132 * class.cs: Factor out some code for handling error handling in
1133 accordance to the "Declarations" section in the "Basic Concepts"
1134 chapter in the ECMA C# spec.
1136 * interface.cs: Make all interface member classes derive from
1137 InterfaceMemberBase.
1139 2001-05-07 Miguel de Icaza <miguel@ximian.com>
1141 * Many things: all interfaces are parsed and generated in
1142 gen-treedump. Support for member variables, constructors,
1143 destructors, properties, constants is there.
1145 Beginning of the IL backend, but very little done, just there for
1148 2001-04-29 Miguel de Icaza <miguel@ximian.com>
1150 * cs-parser.jay: Fix labeled statement.
1152 * cs-tokenizer.cs (escape): Escape " and ' always.
1153 ref_line, ref_name: keep track of the line/filename as instructed
1154 by #line by the compiler.
1157 2001-04-27 Miguel de Icaza <miguel@ximian.com>
1159 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
1160 to match the values in System.CodeDOM.
1162 Divid renamed to Divide.
1164 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
1166 (Statements.set): remove.
1168 * System.CodeDOM/CodeCatchClause.cs: always have a valid
1171 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
1172 falseStatements always have valid values.
1174 * cs-parser.jay: Use System.CodeDOM now.
