497 * class.cs: Catch static methods having the flags override,
500 * expression.cs (UserCast): This user cast was not really doing
501 what it was supposed to do. Which is to be born in fully resolved

506 2001-10-05 Miguel de Icaza <miguel@ximian.com>
508 * expression.cs: Implicity convert the result from UserCast.

576 instead of inside a tight loop.

583 * report.cs: Make all of it static.
585 * rootcontext.cs: Drop object_type and value_type computations, as
586 we have those in the TypeManager anyways.

592 Add --probe option to debug the error reporting system with a test

638 in order from base classes to child classes, so that we can in
639 child classes look up in our parent for method names and
640 attributes (required for handling abstract, virtual, new, override
641 constructs: we need to instrospect our base class, and if we dont
642 populate the classes in order, the introspection might be
643 incorrect. For example, a method could query its parent before
644 the parent has any methods and would determine that the parent has
645 no abstract methods (while it could have had them)).

720 Expression::Literalize): Create literal expressions from
721 FieldInfos which are literals.
723 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
724 type casts, because they were wrong. The test suite in tests

747 * class.cs: Only add constructor to hashtable if it is non-null
748 (as now constructors can fail on define).
750 (TypeManager, Class, Struct): Take location arguments.
752 Catch field instance initialization in structs as errors.
754 accepting_filter: a new filter for FindMembers that is static so
755 that we dont create an instance per invocation.
757 (Constructor::Define): Catch errors where a struct constructor is
760 * cs-parser.jay: Pass location information for various new
763 * delegate.cs (Delegate): take a location argument.
765 * driver.cs: Do not call EmitCode if there were problesm in the
766 Definition of the types, as many Builders wont be there.
768 * decl.cs (Decl::Decl): Require a location argument.
770 * cs-tokenizer.cs: Handle properly hex constants that can not fit
771 into integers, and find the most appropiate integer for it.
773 * literal.cs: Implement ULongLiteral.
775 * rootcontext.cs: Provide better information about the location of
776 failure when CreateType fails.
778 2001-09-29 Miguel de Icaza <miguel@ximian.com>
780 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
783 * expression.cs (Binary::CheckShiftArguments): Add missing type
785 (Binary::ResolveOperator): Add type to the logical and and logical
786 or, Bitwise And/Or and Exclusive Or code paths, it was missing
789 (Binary::DoNumericPromotions): In the case where either argument
790 is ulong (and most signed types combined with ulong cause an
791 error) perform implicit integer constant conversions as well.
793 2001-09-28 Miguel de Icaza <miguel@ximian.com>
795 * expression.cs (UserImplicitCast): Method should always be
797 (Invocation::BetterConversion): Simplified test for IntLiteral.
799 (Expression::ImplicitNumericConversion): Split this routine out.
800 Put the code that performs implicit constant integer conversions
803 (Expression::Resolve): Become a wrapper around DoResolve so we can
804 check eclass and type being set after resolve.
806 (Invocation::Badness): Remove this dead function
808 (Binary::ResolveOperator): Do not compute the expensive argumnets
809 unless we have a union for it.
811 (Probe::Emit): Is needs to do an isinst and then
812 compare against null.
814 (::CanConvert): Added Location argument. If the Location argument
815 is null (Location.Null), then we do not report errors. This is
816 used by the `probe' mechanism of the Explicit conversion. We do
817 not want to generate an error for something that the user
818 explicitly requested to be casted. But the pipeline for an
819 explicit cast first tests for potential implicit casts.
821 So for now, if the Location is null, it means `Probe only' to
822 avoid adding another argument. Might have to revise this
825 (ClassCast): New class used to type cast objects into arbitrary
826 classes (used in Explicit Reference Conversions).
828 Implement `as' as well.
830 Reverted all the patches from Ravi below: they were broken:
832 * The use of `level' as a mechanism to stop recursive
833 invocations is wrong. That was there just to catch the
834 bug with a strack trace but not as a way of addressing
837 To fix the problem we have to *understand* what is going
838 on and the interactions and come up with a plan, not
839 just get things going.
841 * The use of the type conversion cache that I proposed
842 last night had an open topic: How does this work across
843 protection domains. A user defined conversion might not
844 be public in the location where we are applying the
845 conversion, a different conversion might be selected
846 (ie, private A->B (better) but public B->A (worse),
847 inside A, A->B applies, but outside it, B->A will
850 * On top of that (ie, even if the above is solved),
851 conversions in a cache need to be abstract. Ie, `To
852 convert from an Int to a Short use an OpcodeCast', not
853 `To convert from an Int to a Short use the OpcodeCast on
854 the variable 5' (which is what this patch was doing).
856 2001-09-28 Ravi Pratap <ravi@ximian.com>
858 * expression.cs (Invocation::ConversionExists): Re-write to use
861 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
862 cache all conversions done, not just user-defined ones.
864 (Invocation::BetterConversion): The real culprit. Use ConversionExists
865 to determine if a conversion exists instead of acutually trying to
866 perform the conversion. It's faster too.
868 (Expression::ConvertExplicit): Modify to use ConversionExists to check
869 and only then attempt the implicit conversion.
871 2001-09-28 Ravi Pratap <ravi@ximian.com>
873 * expression.cs (ConvertImplicit): Use a cache for conversions
874 already found. Check level of recursion and bail out if necessary.
876 2001-09-28 Miguel de Icaza <miguel@ximian.com>
878 * typemanager.cs (string_concat_string_string, string_concat_object_object):
879 Export standard methods that we expect for string operations.
881 * statement.cs (Block::UsageWarning): Track usage of variables and
882 report the errors for not used variables.
884 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
887 2001-09-27 Miguel de Icaza <miguel@ximian.com>
889 * codegen.cs: remove unnneded code
891 * expression.cs: Removed BuiltinTypeAccess class
893 Fix the order in which implicit conversions are
896 The previous fixed dropped support for boxed conversions (adding a
897 test to the test suite now)
899 (UserImplicitCast::CanConvert): Remove test for source being null,
900 that code is broken. We should not feed a null to begin with, if
901 we do, then we should track the bug where the problem originates
902 and not try to cover it up here.
904 Return a resolved expression of type UserImplicitCast on success
905 rather than true/false. Ravi: this is what I was talking about,
906 the pattern is to use a static method as a "constructor" for
909 Also, do not create arguments until the very last minute,
910 otherwise we always create the arguments even for lookups that
911 will never be performed.
913 (UserImplicitCast::Resolve): Eliminate, objects of type
914 UserImplicitCast are born in a fully resolved state.
916 * typemanager.cs (InitCoreTypes): Init also value_type
919 * expression.cs (Cast::Resolve): First resolve the child expression.
921 (LValue): Add new method AddressOf to be used by
924 Change the argument of Store to take an EmitContext instead of an
925 ILGenerator, because things like FieldExpr need to be able to call
926 their children expression to generate the instance code.
928 (Expression::Error, Expression::Warning): Sugar functions for
931 (Expression::MemberLookup): Accept a TypeContainer instead of a
932 Report as the first argument.
934 (Expression::ResolvePrimary): Killed. I still want to improve
935 this as currently the code is just not right.
937 (Expression::ResolveMemberAccess): Simplify, but it is still
940 (Unary::Resolve): Catch errors in AddressOf operators.
942 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
943 index to a byte for the short-version, or the compiler will choose
944 the wrong Emit call, which generates the wrong data.
946 (ParameterReference::Emit, ::Store): same.
948 (FieldExpr::AddressOf): Implement.
950 * typemanager.cs: TypeManager: made public variable instead of
953 * driver.cs: document --fatal.
955 * report.cs (ErrorMessage, WarningMessage): new names for the old
956 Error and Warning classes.
958 * cs-parser.jay (member_access): Turn built-in access to types
959 into a normal simplename
961 2001-09-27 Ravi Pratap <ravi@ximian.com>
963 * expression.cs (Invocation::BetterConversion): Fix to cope
964 with q being null, since this was introducing a bug.
966 * expression.cs (ConvertImplicit): Do built-in conversions first.
968 2001-09-27 Ravi Pratap <ravi@ximian.com>

974 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
975 I had introduced long ago (what's new ?).
977 * expression.cs (UserImplicitCast::CanConvert): Static method to do
978 the work of all the checking.
979 (ConvertImplicit): Call CanConvert and only then create object if necessary.
980 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
982 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
983 that is the right way.
985 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
986 overloading resolution. Use everywhere instead of cutting and pasting code.
988 (Binary::ResolveOperator): Use MakeUnionSet.
990 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
991 we have to convert to bool types. Not complete yet.
993 2001-09-27 Miguel de Icaza <miguel@ximian.com>
995 * typemanager.cs (TypeManager::CSharpName): support ushort.
997 * expression.cs (Expression::TryImplicitIntConversion): Attempts
998 to provide an expression that performsn an implicit constant int
999 conversion (section 6.1.6).
1000 (Expression::ConvertImplicitRequired): Reworked to include
1001 implicit constant expression conversions.
1003 (Expression::ConvertNumericExplicit): Finished.
1005 (Invocation::Emit): If InstanceExpression is null, then it means
1006 that we perform a call on this.
1008 2001-09-26 Miguel de Icaza <miguel@ximian.com>
1010 * expression.cs (Unary::Emit): Remove some dead code.
1011 (Probe): Implement Resolve and Emit for `is'.
1012 (Expression::ConvertImplicitRequired): Attempt to do constant
1013 expression conversions here. Maybe should be moved to
1014 ConvertImplicit, but I am not sure.
1015 (Expression::ImplicitLongConstantConversionPossible,
1016 Expression::ImplicitIntConstantConversionPossible): New functions
1017 that tell whether is it possible to apply an implicit constant
1018 expression conversion.

1027 (Parameters::VerifyArgs): Verifies that no two arguments have the
1030 * class.cs (Operator): Update the operator names to reflect the
1031 ones that the spec expects (as we are just stringizing the
1034 * expression.cs (Unary::ResolveOperator): Fix bug: Use
1035 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
1036 previous usage did only work for our methods.
1037 (Expression::ConvertImplicit): Handle decimal implicit numeric
1038 conversions as well.
1039 (Expression::InternalTypeConstructor): Used to invoke constructors
1040 on internal types for default promotions.
1042 (Unary::Emit): Implement special handling for the pre/post
1043 increment/decrement for overloaded operators, as they need to have
1044 the same semantics as the other operators.
1046 (Binary::ResolveOperator): ditto.
1047 (Invocation::ConversionExists): ditto.
1048 (UserImplicitCast::Resolve): ditto.
1050 2001-09-26 Ravi Pratap <ravi@ximian.com>

1064 * assign.cs (Assign): Make it inherit from ExpressionStatement.
1066 * expression.cs (ExpressionStatement): New base class used for
1067 expressions that can appear in statements, so that we can provide
1068 an alternate path to generate expression that do not leave a value
1071 (Expression::Emit, and all the derivatives): We no longer return
1072 whether a value is left on the stack or not. Every expression
1073 after being emitted leaves a single value on the stack.
1075 * codegen.cs (EmitContext::EmitStatementExpression): Use the
1076 facilties of ExpressionStatement if possible.
1078 * cs-parser.jay: Update statement_expression.

1099 (ConvertImplicit): Do user-defined conversion if it exists.
1101 2001-09-24 Miguel de Icaza <miguel@ximian.com>
1103 * assign.cs: track location.
1104 (Resolve): Use implicit conversions on assignment.
1106 * literal.cs: Oops. Not good, Emit of short access values should

1109 * expression.cs (Unary::Emit): Emit code for -expr.
1111 (Unary::ResolveOperator): Handle `Substract' for non-constants

1169 * typemanager.cs: declare and load enum_type, delegate_type and
1172 * expression.cs (Expression::Emit): Now emit returns a value that
1173 tells whether a value is left on the stack or not. This strategy
1174 might be reveted tomorrow with a mechanism that would address
1175 multiple assignments.
1176 (Expression::report118): Utility routine to report mismatches on
1179 (Unary::Report23): Report impossible type/operator combination
1182 (Unary::IsIncrementableNumber): Whether the type can be

1228 functions, throw exceptions so it is obvious that we are facing a

1233 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
1234 Use a basename for those routines because .NET does not like paths

1271 * expression.cs (Unary::Resolve): Implement.
1272 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
1273 operators are found instead of making noise ;-)

1278 (Unary::ForceConversion): Copy and Paste !
1280 * class.cs (Operator::Define): Fix a small bug for the case when we have

1304 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
1305 the last instruction contains a return opcode to avoid generating
1306 the last `ret' instruction (this generates correct code, and it is
1307 nice to pass the peverify output).
1309 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
1310 initializer for static and instance variables.
1311 (Constructor::Emit): Allow initializer to be null in the case of
1312 static constructors. Only emit initializer for instance
1315 (TypeContainer::FindMembers): Return a null array if there are no

1325 * driver.cs: Stop compilation if there are parse errors.

1365 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
1368 (Expression::MemberLookup): Provide a version that allows to
1369 specify the MemberTypes and BindingFlags.
1371 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
1372 so it was not fetching variable information from outer blocks.
1374 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
1375 Beforefieldinit as it was buggy.
1377 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
1380 * class.cs (Constructor::Emit): Only emit if block is not null.
1381 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
1382 deal with this by semantically definining it as if the user had
1385 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
1386 constructors as we now "emit" them at a higher level.

1389 default constructors if none was provided.
1391 (ConstructorInitializer): Add methods Resolve and Emit.
1393 * expression.cs: Cast to ConstructorInfo instead of MethodInfo

1398 the default constructor builder with our hashtable for methodbuilders
1401 * expression.cs (Invocation::OverloadResolve): Add a check for pd == null
1402 and argument_count is 0 in which case we have a match.

1431 * rootcontext.cs: Fix bug: tree.Namespaces might be null.
1433 2001-09-16 Ravi Pratap <ravi@ximian.com>
1435 * class.cs (EmitStaticFieldInitializers, EmitFieldInitializers): Make public.
1436 (TypeContainer::EmitConstructor): Remove and move code into Contructor::Emit.

1459 * rootcontext.cs (IsNamespace): Fixed it :-)
1461 2001-09-14 Miguel de Icaza <miguel@ximian.com>
1463 * class.cs (TypeContainer::FindMembers): Add support for

1474 * modifiers.cs: Do not use `parent', instead use the real type
1475 container to evaluate permission settings.
1477 * class.cs: Put Ravi's patch back in. He is right, and we will
1478 have to cope with the
1480 2001-09-14 Ravi Pratap <ravi@ximian.com>
1482 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

1487 * driver.cs: Added --parse option that only parses its input files
1490 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
1491 incorrect. IsTopLevel is not used to tell whether an object is
1492 root_types or not (that can be achieved by testing this ==
1493 root_types). But to see if this is a top-level *class* (not
1494 necessarly our "toplevel" container).
1496 2001-09-14 Ravi Pratap <ravi@ximian.com>
1498 * enum.cs (Enum::Define): Modify to call the Lookup method on the

1503 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
1504 Modifiers.TypeAttr. This should just be a call to that method.
1506 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
1507 object so that we can determine if we are top-level or not.
1509 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the

1520 * modifiers.cs (MethodAttr): Re-write.
1521 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
1523 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
1524 of top-level types as claimed.
1526 2001-09-13 Miguel de Icaza <miguel@ximian.com>
1528 * expression.cs (MemberLookup): Fruitless attempt to lookup
1529 constructors. Maybe I need to emit default constructors? That

1532 (Invocation::EmitArguments): new function, shared by the new

1554 objects that we might have around.
1556 (Populate): Only initialize method_builders_to_methods once.
1558 * expression.cs (PropertyExpr): Initialize type from the
1561 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

1566 (Binary::ResolveOperator): Set the return type to boolean for
1567 comparission operators
1569 * typemanager.cs: Remove debugging print code.
1571 (Invocation::Resolve): resolve type.
1573 * class.cs: Allocate a MemberInfo of the correct size, as the code
1574 elsewhere depends on the test to reflect the correct contents.
1576 (Method::) Keep track of parameters, due to System.Reflection holes
1578 (TypeContainer::Populate): Keep track of MethodBuilders to Method
1581 (TypeContainer::FindMembers): Use ArrayList and then copy an array
1582 of the exact size and return that.
1584 (Class::LookupMethodByBuilder): New function that maps
1585 MethodBuilders to its methods. Required to locate the information
1586 on methods because System.Reflection bit us again.
1588 * support.cs: New file, contains an interface ParameterData and
1589 two implementations: ReflectionParameters and InternalParameters
1590 used to access Parameter information. We will need to grow this
1593 * expression.cs (Invocation::GetParameterData): implement a cache
1594 and a wrapper around the ParameterData creation for methods.
1595 (Invocation::OverloadResolve): Use new code.

1651 2001-09-12 Ravi Pratap <ravi@ximian.com>
1653 * class.cs (TypeContainer::FindMembers): Method which does exactly
1654 what Type.FindMembers does, only we don't have to use reflection. No

2059 AddIndexer method so it gets added ;-)
2061 * ../errors/errors.txt : Update to include new error numbers. Are these numbers
2062 already taken care of by the MS compiler ?
2064 2001-08-29 Ravi Pratap <ravi@che.iitm.ac.in>
2066 * class.cs (Operator): New class for operator declarations.
2067 (Operator::OpType): Enum for the various operators.
2069 2001-08-29 Ravi Pratap <ravi@che.iitm.ac.in>
2071 * class.cs (TypeContainer::AddIndexer): Remove FIXME comment. We
2072 ostensibly handle this in semantic analysis.
2074 * cs-parser.jay (general_catch_clause): Comment out
2075 (specific_catch_clauses, specific_catch_clause): Ditto.
2076 (opt_general_catch_clause, opt_specific_catch_clauses): Ditto
2077 (catch_args, opt_catch_args): New productions.
2078 (catch_clause): Rewrite to use the new productions above
2079 (catch_clauses): Modify accordingly.
2080 (opt_catch_clauses): New production to use in try_statement
2081 (try_statement): Revamp. Basically, we get rid of one unnecessary rule
2082 and re-write the code in the actions to extract the specific and
2083 general catch clauses by being a little smart ;-)
2085 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
2086 Hooray, try and catch statements parse fine !
2088 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2090 * statement.cs (Block::GetVariableType): Fix logic to extract the type
2091 string from the hashtable of variables.
2093 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did
2094 I end up making that mistake ;-)
2095 (catch_clauses): Fixed gross error which made Key and Value of the
2096 DictionaryEntry the same : $1 !!
2098 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2100 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
2102 * cs-parser.jay (event_declaration): Correct to remove the semicolon
2103 when the add and remove accessors are specified.
2105 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2107 * cs-parser.jay (IndexerDeclaration): New helper class to hold
2108 information about indexer_declarator.
2109 (indexer_declarator): Implement actions.
2110 (parsing_indexer): New local boolean used to keep track of whether
2111 we are parsing indexers or properties. This is necessary because
2112 implicit_parameters come into picture even for the get accessor in the
2114 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
2116 * class.cs (Indexer): New class for indexer declarations.
2117 (TypeContainer::AddIndexer): New method to add an indexer to a type.
2118 (TypeContainer::indexers): New member to hold list of indexers for the
2121 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
2123 * cs-parser.jay (add_accessor_declaration): Implement action.
2124 (remove_accessor_declaration): Implement action.
2125 (event_accessors_declaration): Implement
2126 (variable_declarators): swap statements for first rule - trivial.
2128 * class.cs (Event): New class to hold information about event
2130 (TypeContainer::AddEvent): New method to add an event to a type
2131 (TypeContainer::events): New member to hold list of events.
2133 * cs-parser.jay (event_declaration): Implement actions.
2135 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
2137 * cs-parser.jay (dim_separators): Implement. Make it a string
2138 concatenating all the commas together, just as they appear.
2139 (opt_dim_separators): Modify accordingly
2140 (rank_specifiers): Update accordingly. Basically do the same
2141 thing - instead, collect the brackets here.
2142 (opt_rank_sepcifiers): Modify accordingly.
2143 (array_type): Modify to actually return the complete type string
2144 instead of ignoring the rank_specifiers.
2145 (expression_list): Implement to collect the expressions
2146 (variable_initializer): Implement. We make it a list of expressions
2147 essentially so that we can handle the array_initializer case neatly too.
2148 (variable_initializer_list): Implement.
2149 (array_initializer): Make it a list of variable_initializers
2150 (opt_array_initializer): Modify accordingly.
2152 * expression.cs (New::NType): Add enumeration to help us
2153 keep track of whether we have an object/delegate creation
2154 or an array creation.
2155 (New:NewType, New::Rank, New::Indices, New::Initializers): New
2156 members to hold data about array creation.
2157 (New:New): Modify to update NewType
2158 (New:New): New Overloaded contructor for the array creation
2161 * cs-parser.jay (array_creation_expression): Implement to call
2162 the overloaded New constructor.
2164 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
2166 * class.cs (TypeContainer::Constructors): Return member
2167 constructors instead of returning null.
2169 2001-08-26 Miguel de Icaza <miguel@ximian.com>
2171 * typemanager.cs (InitCoreTypes): Initialize the various core
2172 types after we have populated the type manager with the user
2173 defined types (this distinction will be important later while
2174 compiling corlib.dll)
2176 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
2177 on Expression Classification. Now all expressions have a method
2178 `Resolve' and a method `Emit'.
2180 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
2181 generation from working. Also add some temporary debugging
2184 2001-08-24 Miguel de Icaza <miguel@ximian.com>
2186 * codegen.cs: Lots of code generation pieces. This is only the
2187 beginning, will continue tomorrow with more touches of polish. We
2188 handle the fundamentals of if, while, do, for, return. Others are
2189 trickier and I need to start working on invocations soon.
2191 * gen-treedump.cs: Bug fix, use s.Increment here instead of
2194 * codegen.cs (EmitContext): New struct, used during code
2195 emission to keep a context. Most of the code generation will be
2198 * cs-parser.jay: Add embedded blocks to the list of statements of
2199 this block. So code generation proceeds in a top down fashion.
2201 2001-08-23 Miguel de Icaza <miguel@ximian.com>
2203 * statement.cs: Add support for multiple child blocks.
2205 2001-08-22 Miguel de Icaza <miguel@ximian.com>
2207 * codegen.cs (EmitCode): New function, will emit the code for a
2208 Block of code given a TypeContainer and its ILGenerator.
2210 * statement.cs (Block): Standard public readonly optimization.
2211 (Block::Block constructors): Link children.
2212 (Block::Child): Child Linker.
2213 (Block::EmitVariables): Emits IL variable declarations.
2215 * class.cs: Drop support for MethodGroups here, delay until
2217 (Method::): Applied the same simplification that I did before, and
2218 move from Properties to public readonly fields.
2219 (Method::ParameterTypes): Returns the parameter types for the
2220 function, and implements a cache that will be useful later when I
2221 do error checking and the semantic analysis on the methods is
2223 (Constructor::GetCallingConvention): Renamed from CallingConvetion
2224 and made a method, optional argument tells whether this is a class
2225 or a structure to apply the `has-this' bit.
2226 (Method::GetCallingConvention): Implement, returns the calling
2228 (Method::Define): Defines the type, a second pass is performed
2229 later to populate the methods.
2231 (Constructor::ParameterTypes): implement a cache similar to the
2232 one on Method::ParameterTypes, useful later when we do semantic
2235 (TypeContainer::EmitMethod): New method. Emits methods.
2237 * expression.cs: Removed MethodGroup class from here.
2239 * parameter.cs (Parameters::GetCallingConvention): new method.
2241 2001-08-21 Miguel de Icaza <miguel@ximian.com>
2243 * class.cs (TypeContainer::Populate): Drop RootContext from the
2246 (Constructor::CallingConvention): Returns the calling convention.
2247 (Constructor::ParameterTypes): Returns the constructor parameter
2250 (TypeContainer::AddConstructor): Keep track of default constructor
2251 and the default static constructor.
2253 (Constructor::) Another class that starts using `public readonly'
2254 instead of properties.
2256 (Constructor::IsDefault): Whether this is a default constructor.
2258 (Field::) use readonly public fields instead of properties also.
2260 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
2261 track of static constructors; If none is used, turn on
2262 BeforeFieldInit in the TypeAttributes.
2264 * cs-parser.jay (opt_argument_list): now the return can be null
2265 for the cases where there are no arguments.
2267 (constructor_declarator): If there is no implicit `base' or
2268 `this', then invoke the default parent constructor.
2270 * modifiers.cs (MethodAttr): New static function maps a set of
2271 modifiers flags into a MethodAttributes enum
2272 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
2273 MethodAttr, TypeAttr to represent the various mappings where the
2275 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
2277 2001-08-19 Miguel de Icaza <miguel@ximian.com>
2279 * parameter.cs (GetParameterInfo): Fix bug where there would be no
2282 * interface.cs (PopulateIndexer): Implemented the code generator
2283 for interface indexers.
2285 2001-08-17 Miguel de Icaza <miguel@ximian.com>
2287 * interface.cs (InterfaceMemberBase): Now we track the new status
2290 (PopulateProperty): Implement property population. Woohoo! Got
2291 Methods and Properties going today.
2293 Removed all the properties for interfaces, and replaced them with
2294 `public readonly' fields.
2296 2001-08-16 Miguel de Icaza <miguel@ximian.com>
2298 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
2299 initialize their hashtables/arraylists only when they are needed
2300 instead of doing this always.
2302 * parameter.cs: Handle refs and out parameters.
2304 * cs-parser.jay: Use an ArrayList to construct the arguments
2305 instead of the ParameterCollection, and then cast that to a
2308 * parameter.cs: Drop the use of ParameterCollection and use
2309 instead arrays of Parameters.
2311 (GetParameterInfo): Use the Type, not the Name when resolving
2314 2001-08-13 Miguel de Icaza <miguel@ximian.com>
2316 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
2317 and instead use public readonly fields.
2319 * class.cs: Put back walking code for type containers.
2321 2001-08-11 Miguel de Icaza <miguel@ximian.com>
2323 * class.cs (MakeConstant): Code to define constants.
2325 * rootcontext.cs (LookupType): New function. Used to locate types
2328 2001-08-08 Miguel de Icaza <miguel@ximian.com>
2330 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
2331 this System.Reflection code is. Kudos to Microsoft
2333 * typemanager.cs: Implement a type cache and avoid loading all
2334 types at boot time. Wrap in LookupType the internals. This made
2335 the compiler so much faster. Wow. I rule!
2337 * driver.cs: Make sure we always load mscorlib first (for
2338 debugging purposes, nothing really important).
2340 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
2341 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
2343 * rootcontext.cs: Lookup types on their namespace; Lookup types
2344 on namespaces that have been imported using the `using' keyword.
2346 * class.cs (TypeContainer::TypeAttr): Virtualize.
2347 (Class::TypeAttr): Return attributes suitable for this bad boy.
2348 (Struct::TypeAttr): ditto.
2349 Handle nested classes.
2350 (TypeContainer::) Remove all the type visiting code, it is now
2351 replaced with the rootcontext.cs code
2353 * rootcontext.cs (GetClassBases): Added support for structs.
2355 2001-08-06 Miguel de Icaza <miguel@ximian.com>
2357 * interface.cs, statement.cs, class.cs, parameter.cs,
2358 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
2359 Drop use of TypeRefs, and use strings instead.
2361 2001-08-04 Miguel de Icaza <miguel@ximian.com>
2365 * class.cs (Struct::Struct): set the SEALED flags after
2366 checking the modifiers.
2367 (TypeContainer::TypeAttr): new property, returns the
2368 TypeAttributes for a class.
2370 * cs-parser.jay (type_list): Oops, list production was creating a
2371 new list of base types.
2373 * rootcontext.cs (StdLib): New property.
2374 (GetInterfaceTypeByName): returns an interface by type name, and
2375 encapsulates error handling here.
2376 (GetInterfaces): simplified.
2377 (ResolveTree): Encapsulated all the tree resolution here.
2378 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
2381 * driver.cs: Add support for --nostdlib, to avoid loading the
2383 (Main): Do not put tree resolution here.
2385 * rootcontext.cs: Beginning of the class resolution.
2387 2001-08-03 Miguel de Icaza <miguel@ximian.com>
2389 * rootcontext.cs: Provide better error reporting.
2391 * cs-parser.jay (interface_base): set our $$ to be interfaces.
2393 * rootcontext.cs (CreateInterface): Handle the case where there
2394 are no parent interfaces.
2396 (CloseTypes): Routine to flush types at the end.
2397 (CreateInterface): Track types.
2398 (GetInterfaces): Returns an array of Types from the list of
2401 * typemanager.c (AddUserType): Mechanism to track user types (puts
2402 the type on the global type hash, and allows us to close it at the
2405 2001-08-02 Miguel de Icaza <miguel@ximian.com>
2407 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
2408 RecordInterface instead.
2410 * cs-parser.jay: Updated to reflect changes above.
2412 * decl.cs (Definition): Keep track of the TypeBuilder type that
2413 represents this type here. Not sure we will use it in the long
2414 run, but wont hurt for now.
2416 * driver.cs: Smaller changes to accomodate the new code.
2418 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
2421 * rootcontext.cs (CreateInterface): New method, used to create
2422 the System.TypeBuilder type for interfaces.
2423 (ResolveInterfaces): new entry point to resolve the interface
2425 (CodeGen): Property, used to keep track of the code generator.
2427 2001-07-26 Miguel de Icaza <miguel@ximian.com>
2429 * cs-parser.jay: Add a second production for delegate_declaration
2432 (enum_body): Put an opt_comma here instead of putting it on
2433 enum_body or enum_member_declarations so we can handle trailing
2434 commas on enumeration members. Gets rid of a shift/reduce.
2436 (type_list): Need a COMMA in the middle.
2438 (indexer_declaration): Tell tokenizer to recognize get/set
2440 * Remove old targets.
2442 * Re-add the parser target.
2444 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2446 * cs-parser.jay: Add precendence rules for a number of operators
2447 ot reduce the number of shift/reduce conflicts in the grammar.
2449 2001-07-17 Miguel de Icaza <miguel@ximian.com>
2451 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
2454 Get rid of old crufty code.
2456 * rootcontext.cs: Use this to keep track of the parsed
2457 representation and the defined types available to the program.
2459 * gen-treedump.cs: adjust for new convention.
2461 * type.cs: Split out the type manager, and the assembly builder
2464 * typemanager.cs: the type manager will live here now.
2466 * cil-codegen.cs: And the code generator here.
2468 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
2470 * makefile: Fixed up for easy making.
2472 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2474 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
2477 (unary_expression): Expand pre_increment_expression and
2478 post_decrement_expression to reduce a shift/reduce.
2480 2001-07-11 Simon Cozens
2482 * cs-tokenizer.cs: Hex numbers should begin with a 0.
2484 Improve allow_keyword_as_indent name.
2486 2001-06-19 Miguel de Icaza <miguel@ximian.com>
2488 * Adjustments for Beta2.
2490 2001-06-13 Miguel de Icaza <miguel@ximian.com>
2492 * decl.cs: Added `Define' abstract method.
2493 (InTransit): new property, used to catch recursive definitions.
2495 * interface.cs: Implement `Define'.
2497 * modifiers.cs: Map Modifiers.constants to
2498 System.Reflection.TypeAttribute flags.
2500 * class.cs: Keep track of types and user-defined types.
2501 (BuilderInit): New method for creating an assembly
2502 (ResolveType): New function to launch the resolution process, only
2503 used by interfaces for now.
2505 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
2506 that are inserted into the name space.
2508 2001-06-08 Miguel de Icaza <miguel@ximian.com>
2510 * ARGH. I have screwed up my tree so many times due to the use of
2511 rsync rather than using CVS. Going to fix this at once.
2513 * driver.cs: Objetify driver. Load assemblies, use assemblies to
2516 2001-06-07 Miguel de Icaza <miguel@ximian.com>
2518 * Experiment successful: Use System.Type rather that our own
2521 2001-05-25 Miguel de Icaza <miguel@ximian.com>
2523 * cs-parser.jay: Removed nsAliases from here.
2525 Use new namespaces, handle `using XXX;'
2527 * namespace.cs: Reimplemented namespace handling, use a recursive
2528 definition of the class. Now we can keep track of using clauses
2529 and catch invalid using clauses.
2531 2001-05-24 Miguel de Icaza <miguel@ximian.com>
2533 * gen-treedump.cs: Adapted for all the renaming.
2535 * expression.cs (Expression): this class now has a Type property
2536 which returns an expression Type.
2538 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
2539 `Type', as this has a different meaning now in the base
2541 2001-05-22 Miguel de Icaza <miguel@ximian.com>
2543 * interface.cs, class.cs: Removed from all the sources the
2544 references to signature computation, as we can not do method
2545 signature computation during the parsing time, as we are not
2546 trying to solve at that point distinguishing:
2550 void a (NS.Blah x) {}
2553 Which depending on the context might be valid or not, as we do not
2554 know if Blah is the same thing as NS.Blah at that point.
2556 * Redid everything so the code uses TypeRefs now instead of
2557 Types. TypeRefs are just temporary type placeholders, that need
2558 to be resolved. They initially have a pointer to a string and the
2559 current scope in which they are used. This is used later by the
2560 compiler to resolve the reference to an actual Type.
2562 * DeclSpace is no longer a CIR.Type, and neither are
2563 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
2564 are all DeclSpaces, but no Types.
2566 * type.cs (TypeRefManager): This implements the TypeRef manager,
2567 which keeps track of all the types that need to be resolved after
2568 the parsing has finished.
2570 2001-05-13 Miguel de Icaza <miguel@ximian.com>
2572 * ARGH. We are going to have to store `foreach' as a class rather
2573 than resolving it, as we need to verify error 1579 after name
2574 resolution. *OR* we could keep a flag that says `This request to
2575 IEnumerator comes from a foreach statement' which we can then use
2576 to generate the error.
2578 2001-05-10 Miguel de Icaza <miguel@ximian.com>
2580 * class.cs (TypeContainer.AddMethod): we now add methods to the
2581 MethodGroup instead of the method hashtable.
2583 * expression.cs: Add MethodGroup abstraction, which gets us one
2584 step closer to the specification in the way we handle method
2587 * cs-parser.jay (primary_expression): qualified_identifier now
2588 tried to match up an identifier to a local variable reference or
2589 to a parameter reference.
2591 current_local_parameters is now a parser global variable that
2592 points to the current parameters for the block, used during name
2595 (property_declaration): Now creates an implicit `value' argument to
2598 2001-05-09 Miguel de Icaza <miguel@ximian.com>
2600 * parameter.cs: Do not use `param' arguments as part of the
2601 signature, per the spec.
2603 2001-05-08 Miguel de Icaza <miguel@ximian.com>
2605 * decl.cs: Base class for classes, structs and interfaces. This
2606 is the "Declaration Space"
2608 * cs-parser.jay: Use CheckDef for checking declaration errors
2609 instead of having one on each function.
2611 * class.cs: Factor out some code for handling error handling in
2612 accordance to the "Declarations" section in the "Basic Concepts"
2613 chapter in the ECMA C# spec.
2615 * interface.cs: Make all interface member classes derive from
2616 InterfaceMemberBase.
2618 2001-05-07 Miguel de Icaza <miguel@ximian.com>
2620 * Many things: all interfaces are parsed and generated in
2621 gen-treedump. Support for member variables, constructors,
2622 destructors, properties, constants is there.
2624 Beginning of the IL backend, but very little done, just there for
2627 2001-04-29 Miguel de Icaza <miguel@ximian.com>
2629 * cs-parser.jay: Fix labeled statement.
2631 * cs-tokenizer.cs (escape): Escape " and ' always.
2632 ref_line, ref_name: keep track of the line/filename as instructed
2633 by #line by the compiler.
2636 2001-04-27 Miguel de Icaza <miguel@ximian.com>
2638 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
2639 to match the values in System.CodeDOM.
2641 Divid renamed to Divide.
2643 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
2645 (Statements.set): remove.
2647 * System.CodeDOM/CodeCatchClause.cs: always have a valid
2650 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
2651 falseStatements always have valid values.
2653 * cs-parser.jay: Use System.CodeDOM now.
