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

464 2001-10-05 Miguel de Icaza <miguel@ximian.com>
466 * expression.cs: Implicity convert the result from UserCast.

534 instead of inside a tight loop.

541 * report.cs: Make all of it static.
543 * rootcontext.cs: Drop object_type and value_type computations, as
544 we have those in the TypeManager anyways.
546 Drop report instance variable too, now it is a global.
548 * driver.cs: Use try/catch on command line handling.
550 Add --probe option to debug the error reporting system with a test

593 2001-10-03 Miguel de Icaza <miguel@ximian.com>
595 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
596 in order from base classes to child classes, so that we can in
597 child classes look up in our parent for method names and
598 attributes (required for handling abstract, virtual, new, override
599 constructs: we need to instrospect our base class, and if we dont
600 populate the classes in order, the introspection might be
601 incorrect. For example, a method could query its parent before
602 the parent has any methods and would determine that the parent has
603 no abstract methods (while it could have had them)).

678 Expression::Literalize): Create literal expressions from
679 FieldInfos which are literals.
681 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
682 type casts, because they were wrong. The test suite in tests

748 is ulong (and most signed types combined with ulong cause an
749 error) perform implicit integer constant conversions as well.
751 2001-09-28 Miguel de Icaza <miguel@ximian.com>
753 * expression.cs (UserImplicitCast): Method should always be
755 (Invocation::BetterConversion): Simplified test for IntLiteral.
757 (Expression::ImplicitNumericConversion): Split this routine out.
758 Put the code that performs implicit constant integer conversions
761 (Expression::Resolve): Become a wrapper around DoResolve so we can
762 check eclass and type being set after resolve.
764 (Invocation::Badness): Remove this dead function
766 (Binary::ResolveOperator): Do not compute the expensive argumnets
767 unless we have a union for it.
769 (Probe::Emit): Is needs to do an isinst and then
770 compare against null.
772 (::CanConvert): Added Location argument. If the Location argument
773 is null (Location.Null), then we do not report errors. This is
774 used by the `probe' mechanism of the Explicit conversion. We do
775 not want to generate an error for something that the user
776 explicitly requested to be casted. But the pipeline for an
777 explicit cast first tests for potential implicit casts.
779 So for now, if the Location is null, it means `Probe only' to
780 avoid adding another argument. Might have to revise this
783 (ClassCast): New class used to type cast objects into arbitrary
784 classes (used in Explicit Reference Conversions).
786 Implement `as' as well.
788 Reverted all the patches from Ravi below: they were broken:
790 * The use of `level' as a mechanism to stop recursive
791 invocations is wrong. That was there just to catch the
792 bug with a strack trace but not as a way of addressing
795 To fix the problem we have to *understand* what is going
796 on and the interactions and come up with a plan, not
797 just get things going.
799 * The use of the type conversion cache that I proposed
800 last night had an open topic: How does this work across
801 protection domains. A user defined conversion might not
802 be public in the location where we are applying the
803 conversion, a different conversion might be selected
804 (ie, private A->B (better) but public B->A (worse),
805 inside A, A->B applies, but outside it, B->A will
808 * On top of that (ie, even if the above is solved),
809 conversions in a cache need to be abstract. Ie, `To
810 convert from an Int to a Short use an OpcodeCast', not
811 `To convert from an Int to a Short use the OpcodeCast on
812 the variable 5' (which is what this patch was doing).
814 2001-09-28 Ravi Pratap <ravi@ximian.com>
816 * expression.cs (Invocation::ConversionExists): Re-write to use
819 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
820 cache all conversions done, not just user-defined ones.
822 (Invocation::BetterConversion): The real culprit. Use ConversionExists
823 to determine if a conversion exists instead of acutually trying to
824 perform the conversion. It's faster too.
826 (Expression::ConvertExplicit): Modify to use ConversionExists to check
827 and only then attempt the implicit conversion.
829 2001-09-28 Ravi Pratap <ravi@ximian.com>
831 * expression.cs (ConvertImplicit): Use a cache for conversions
832 already found. Check level of recursion and bail out if necessary.
834 2001-09-28 Miguel de Icaza <miguel@ximian.com>
836 * typemanager.cs (string_concat_string_string, string_concat_object_object):
837 Export standard methods that we expect for string operations.
839 * statement.cs (Block::UsageWarning): Track usage of variables and
840 report the errors for not used variables.
842 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
845 2001-09-27 Miguel de Icaza <miguel@ximian.com>
847 * codegen.cs: remove unnneded code
849 * expression.cs: Removed BuiltinTypeAccess class
851 Fix the order in which implicit conversions are
854 The previous fixed dropped support for boxed conversions (adding a
855 test to the test suite now)
857 (UserImplicitCast::CanConvert): Remove test for source being null,
858 that code is broken. We should not feed a null to begin with, if
859 we do, then we should track the bug where the problem originates
860 and not try to cover it up here.
862 Return a resolved expression of type UserImplicitCast on success
863 rather than true/false. Ravi: this is what I was talking about,
864 the pattern is to use a static method as a "constructor" for
867 Also, do not create arguments until the very last minute,
868 otherwise we always create the arguments even for lookups that
869 will never be performed.
871 (UserImplicitCast::Resolve): Eliminate, objects of type
872 UserImplicitCast are born in a fully resolved state.
874 * typemanager.cs (InitCoreTypes): Init also value_type
877 * expression.cs (Cast::Resolve): First resolve the child expression.
879 (LValue): Add new method AddressOf to be used by
882 Change the argument of Store to take an EmitContext instead of an
883 ILGenerator, because things like FieldExpr need to be able to call
884 their children expression to generate the instance code.
886 (Expression::Error, Expression::Warning): Sugar functions for
889 (Expression::MemberLookup): Accept a TypeContainer instead of a
890 Report as the first argument.
892 (Expression::ResolvePrimary): Killed. I still want to improve
893 this as currently the code is just not right.
895 (Expression::ResolveMemberAccess): Simplify, but it is still
898 (Unary::Resolve): Catch errors in AddressOf operators.
900 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
901 index to a byte for the short-version, or the compiler will choose
902 the wrong Emit call, which generates the wrong data.
904 (ParameterReference::Emit, ::Store): same.
906 (FieldExpr::AddressOf): Implement.
908 * typemanager.cs: TypeManager: made public variable instead of
911 * driver.cs: document --fatal.
913 * report.cs (ErrorMessage, WarningMessage): new names for the old
914 Error and Warning classes.
916 * cs-parser.jay (member_access): Turn built-in access to types
917 into a normal simplename
919 2001-09-27 Ravi Pratap <ravi@ximian.com>

935 * expression.cs (UserImplicitCast::CanConvert): Static method to do
936 the work of all the checking.
937 (ConvertImplicit): Call CanConvert and only then create object if necessary.
938 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
940 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
941 that is the right way.
943 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
944 overloading resolution. Use everywhere instead of cutting and pasting code.
946 (Binary::ResolveOperator): Use MakeUnionSet.
948 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
949 we have to convert to bool types. Not complete yet.
951 2001-09-27 Miguel de Icaza <miguel@ximian.com>
953 * typemanager.cs (TypeManager::CSharpName): support ushort.
955 * expression.cs (Expression::TryImplicitIntConversion): Attempts
956 to provide an expression that performsn an implicit constant int
957 conversion (section 6.1.6).
958 (Expression::ConvertImplicitRequired): Reworked to include
959 implicit constant expression conversions.
961 (Expression::ConvertNumericExplicit): Finished.
963 (Invocation::Emit): If InstanceExpression is null, then it means
964 that we perform a call on this.
966 2001-09-26 Miguel de Icaza <miguel@ximian.com>
968 * expression.cs (Unary::Emit): Remove some dead code.
969 (Probe): Implement Resolve and Emit for `is'.
970 (Expression::ConvertImplicitRequired): Attempt to do constant
971 expression conversions here. Maybe should be moved to
972 ConvertImplicit, but I am not sure.
973 (Expression::ImplicitLongConstantConversionPossible,
974 Expression::ImplicitIntConstantConversionPossible): New functions
975 that tell whether is it possible to apply an implicit constant
976 expression conversion.

988 * class.cs (Operator): Update the operator names to reflect the
989 ones that the spec expects (as we are just stringizing the
992 * expression.cs (Unary::ResolveOperator): Fix bug: Use
993 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
994 previous usage did only work for our methods.
995 (Expression::ConvertImplicit): Handle decimal implicit numeric
997 (Expression::InternalTypeConstructor): Used to invoke constructors
998 on internal types for default promotions.
1000 (Unary::Emit): Implement special handling for the pre/post
1001 increment/decrement for overloaded operators, as they need to have
1002 the same semantics as the other operators.
1004 (Binary::ResolveOperator): ditto.
1005 (Invocation::ConversionExists): ditto.
1006 (UserImplicitCast::Resolve): ditto.

1025 expressions that can appear in statements, so that we can provide
1026 an alternate path to generate expression that do not leave a value
1029 (Expression::Emit, and all the derivatives): We no longer return
1030 whether a value is left on the stack or not. Every expression
1031 after being emitted leaves a single value on the stack.
1033 * codegen.cs (EmitContext::EmitStatementExpression): Use the
1034 facilties of ExpressionStatement if possible.
1036 * cs-parser.jay: Update statement_expression.

1061 * assign.cs: track location.
1062 (Resolve): Use implicit conversions on assignment.
1064 * literal.cs: Oops. Not good, Emit of short access values should

1067 * expression.cs (Unary::Emit): Emit code for -expr.
1069 (Unary::ResolveOperator): Handle `Substract' for non-constants

1127 * typemanager.cs: declare and load enum_type, delegate_type and
1130 * expression.cs (Expression::Emit): Now emit returns a value that
1131 tells whether a value is left on the stack or not. This strategy
1132 might be reveted tomorrow with a mechanism that would address
1133 multiple assignments.
1134 (Expression::report118): Utility routine to report mismatches on
1137 (Unary::Report23): Report impossible type/operator combination

1191 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
1192 Use a basename for those routines because .NET does not like paths

1225 * cs-parser.jay (unary_expression): Update to use the new names.
1227 * gen-treedump.cs (GetUnary): Same here.
1229 * expression.cs (Unary::Resolve): Implement.
1230 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
1231 operators are found instead of making noise ;-)

1263 the last instruction contains a return opcode to avoid generating
1264 the last `ret' instruction (this generates correct code, and it is

1268 initializer for static and instance variables.
1269 (Constructor::Emit): Allow initializer to be null in the case of

1273 (TypeContainer::FindMembers): Return a null array if there are no

1326 (Expression::MemberLookup): Provide a version that allows to
1327 specify the MemberTypes and BindingFlags.

1332 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
1333 Beforefieldinit as it was buggy.
1335 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
1338 * class.cs (Constructor::Emit): Only emit if block is not null.
1339 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
1340 deal with this by semantically definining it as if the user had

1423 (MethodCore): New class that encapsulates both the shared aspects
1424 of a Constructor and a Method.
1425 (Method, Constructor): Factored pieces into MethodCore.
1427 * driver.cs: Added --fatal which makes errors throw exceptions.
1428 Load System assembly as well as part of the standard library.
1430 * report.cs: Allow throwing exceptions on errors for debugging.
1432 * modifiers.cs: Do not use `parent', instead use the real type
1433 container to evaluate permission settings.
1435 * class.cs: Put Ravi's patch back in. He is right, and we will
1436 have to cope with the
1438 2001-09-14 Ravi Pratap <ravi@ximian.com>
1440 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
1441 FamORAssem, not FamANDAssem.
1443 2001-09-14 Miguel de Icaza <miguel@ximian.com>
1445 * driver.cs: Added --parse option that only parses its input files
1448 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
1449 incorrect. IsTopLevel is not used to tell whether an object is
1450 root_types or not (that can be achieved by testing this ==
1451 root_types). But to see if this is a top-level *class* (not
1452 necessarly our "toplevel" container).
1454 2001-09-14 Ravi Pratap <ravi@ximian.com>
1456 * enum.cs (Enum::Define): Modify to call the Lookup method on the
1457 parent instead of a direct call to GetType.
1459 2001-09-14 Ravi Pratap <ravi@ximian.com>
1461 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
1462 Modifiers.TypeAttr. This should just be a call to that method.
1464 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
1465 object so that we can determine if we are top-level or not.
1467 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
1470 * enum.cs (Enum::Define): Ditto.
1472 * modifiers.cs (FieldAttr): Re-write.

1475 (TypeContainer::HaveStaticConstructor): New property to provide access
1476 to precisely that info.
1478 * modifiers.cs (MethodAttr): Re-write.
1479 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
1481 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
1482 of top-level types as claimed.
1484 2001-09-13 Miguel de Icaza <miguel@ximian.com>
1486 * expression.cs (MemberLookup): Fruitless attempt to lookup
1487 constructors. Maybe I need to emit default constructors? That
1488 might be it (currently .NET emits this for me automatically).
1489 (Invocation::OverloadResolve): Cope with Arguments == null.
1490 (Invocation::EmitArguments): new function, shared by the new
1492 (Invocation::Emit): Handle static and instance methods. Emit

1504 SimpleLookup): Auxiliary routines to help parse a qualifier
1507 Update qualifier_identifier rule.
1509 * codegen.cs: Removed debugging messages.
1511 * class.cs: Make this a global thing, this acts just as a "key" to
1512 objects that we might have around.
1514 (Populate): Only initialize method_builders_to_methods once.
1516 * expression.cs (PropertyExpr): Initialize type from the
1519 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
1520 Resolve pattern. Attempt to implicitly convert value to boolean.
1523 * expression.cs: Set the type for the int32/int32 argument case.
1524 (Binary::ResolveOperator): Set the return type to boolean for
1525 comparission operators
1527 * typemanager.cs: Remove debugging print code.
1529 (Invocation::Resolve): resolve type.
1531 * class.cs: Allocate a MemberInfo of the correct size, as the code
1532 elsewhere depends on the test to reflect the correct contents.
1534 (Method::) Keep track of parameters, due to System.Reflection holes
1536 (TypeContainer::Populate): Keep track of MethodBuilders to Method
1539 (TypeContainer::FindMembers): Use ArrayList and then copy an array
1540 of the exact size and return that.
1542 (Class::LookupMethodByBuilder): New function that maps
1543 MethodBuilders to its methods. Required to locate the information
1544 on methods because System.Reflection bit us again.
1546 * support.cs: New file, contains an interface ParameterData and
1547 two implementations: ReflectionParameters and InternalParameters
1548 used to access Parameter information. We will need to grow this
1551 * expression.cs (Invocation::GetParameterData): implement a cache
1552 and a wrapper around the ParameterData creation for methods.
1553 (Invocation::OverloadResolve): Use new code.
1555 2001-09-13 Ravi Pratap <ravi@ximian.com>

1559 (Field.FieldBuilder): New member.
1560 (TypeContainer::Populate): Update accordingly.
1561 (TypeContainer::FindMembers): Implement.

1577 (ParameterReference::Emit): Implement.
1579 * cs-parser.jay: Fix bug introduced by Ravi, variable initializers

1582 * typemanager.cs (CSharpName): Returns the C# name of a type if
1585 * expression.cs (Expression::ConvertImplicit): New function that

1609 2001-09-12 Ravi Pratap <ravi@ximian.com>
1611 * class.cs (TypeContainer::FindMembers): Method which does exactly
1612 what Type.FindMembers does, only we don't have to use reflection. No
1615 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
1616 typecontainer objects as we need to get at them.
1617 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

1644 (Event::Define): Ditto.
1645 (Property::Define): Ditto.
1647 2001-09-10 Ravi Pratap <ravi@ximian.com>

1650 (TypeContainer.Operators): New property to access the list of operators
1652 (Operator.OperatorMethodBuilder): New member to hold the method builder
1653 for the operator we are defining.

1659 addOn_ and removeOn_
1661 * genericparser.cs (GenericParser::error): Overloaded method to handle the case

1663 error reporting should be done through the Report object.
1665 * class.cs (TypeContainer.Indexers): New property to access the list of indexers.
1666 (Populate): Iterate thru the indexers we have and define them too.

1708 (CheckBinaryOperator): Same here.
1710 * rootcontext.cs (LookupType): Add an extra lookup which simply does a lookup
1711 on the name without any prefixes of namespace names etc. This is because we
1712 already might have something already fully qualified like
1713 'System.Console.WriteLine'

1864 will is used during the tree rewriting as we resolve them during
1867 (Expression::MemberLookup): Implements the MemberLookup (7.3) from

1991 * class.cs (Property): Revamp to use the convention of making fields readonly.

2039 (try_statement): Revamp. Basically, we get rid of one unnecessary rule
2040 and re-write the code in the actions to extract the specific and
2041 general catch clauses by being a little smart ;-)
2043 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
2044 Hooray, try and catch statements parse fine !
2046 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2048 * statement.cs (Block::GetVariableType): Fix logic to extract the type
2049 string from the hashtable of variables.
2051 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did
2052 I end up making that mistake ;-)
2053 (catch_clauses): Fixed gross error which made Key and Value of the
2054 DictionaryEntry the same : $1 !!
2056 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2058 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
2060 * cs-parser.jay (event_declaration): Correct to remove the semicolon
2061 when the add and remove accessors are specified.
2063 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2065 * cs-parser.jay (IndexerDeclaration): New helper class to hold
2066 information about indexer_declarator.
2067 (indexer_declarator): Implement actions.
2068 (parsing_indexer): New local boolean used to keep track of whether
2069 we are parsing indexers or properties. This is necessary because
2070 implicit_parameters come into picture even for the get accessor in the
2072 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
2074 * class.cs (Indexer): New class for indexer declarations.
2075 (TypeContainer::AddIndexer): New method to add an indexer to a type.
2076 (TypeContainer::indexers): New member to hold list of indexers for the
2079 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
2081 * cs-parser.jay (add_accessor_declaration): Implement action.
2082 (remove_accessor_declaration): Implement action.
2083 (event_accessors_declaration): Implement
2084 (variable_declarators): swap statements for first rule - trivial.
2086 * class.cs (Event): New class to hold information about event
2088 (TypeContainer::AddEvent): New method to add an event to a type
2089 (TypeContainer::events): New member to hold list of events.
2091 * cs-parser.jay (event_declaration): Implement actions.
2093 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
2095 * cs-parser.jay (dim_separators): Implement. Make it a string
2096 concatenating all the commas together, just as they appear.
2097 (opt_dim_separators): Modify accordingly
2098 (rank_specifiers): Update accordingly. Basically do the same
2099 thing - instead, collect the brackets here.
2100 (opt_rank_sepcifiers): Modify accordingly.
2101 (array_type): Modify to actually return the complete type string
2102 instead of ignoring the rank_specifiers.
2103 (expression_list): Implement to collect the expressions
2104 (variable_initializer): Implement. We make it a list of expressions
2105 essentially so that we can handle the array_initializer case neatly too.
2106 (variable_initializer_list): Implement.
2107 (array_initializer): Make it a list of variable_initializers
2108 (opt_array_initializer): Modify accordingly.
2110 * expression.cs (New::NType): Add enumeration to help us
2111 keep track of whether we have an object/delegate creation
2112 or an array creation.
2113 (New:NewType, New::Rank, New::Indices, New::Initializers): New
2114 members to hold data about array creation.
2115 (New:New): Modify to update NewType
2116 (New:New): New Overloaded contructor for the array creation
2119 * cs-parser.jay (array_creation_expression): Implement to call
2120 the overloaded New constructor.
2122 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
2124 * class.cs (TypeContainer::Constructors): Return member
2125 constructors instead of returning null.
2127 2001-08-26 Miguel de Icaza <miguel@ximian.com>
2129 * typemanager.cs (InitCoreTypes): Initialize the various core
2130 types after we have populated the type manager with the user
2131 defined types (this distinction will be important later while
2132 compiling corlib.dll)
2134 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
2135 on Expression Classification. Now all expressions have a method
2136 `Resolve' and a method `Emit'.
2138 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
2139 generation from working. Also add some temporary debugging
2142 2001-08-24 Miguel de Icaza <miguel@ximian.com>
2144 * codegen.cs: Lots of code generation pieces. This is only the
2145 beginning, will continue tomorrow with more touches of polish. We
2146 handle the fundamentals of if, while, do, for, return. Others are
2147 trickier and I need to start working on invocations soon.
2149 * gen-treedump.cs: Bug fix, use s.Increment here instead of
2152 * codegen.cs (EmitContext): New struct, used during code
2153 emission to keep a context. Most of the code generation will be
2156 * cs-parser.jay: Add embedded blocks to the list of statements of
2157 this block. So code generation proceeds in a top down fashion.
2159 2001-08-23 Miguel de Icaza <miguel@ximian.com>
2161 * statement.cs: Add support for multiple child blocks.
2163 2001-08-22 Miguel de Icaza <miguel@ximian.com>
2165 * codegen.cs (EmitCode): New function, will emit the code for a
2166 Block of code given a TypeContainer and its ILGenerator.
2168 * statement.cs (Block): Standard public readonly optimization.
2169 (Block::Block constructors): Link children.
2170 (Block::Child): Child Linker.
2171 (Block::EmitVariables): Emits IL variable declarations.
2173 * class.cs: Drop support for MethodGroups here, delay until
2175 (Method::): Applied the same simplification that I did before, and
2176 move from Properties to public readonly fields.
2177 (Method::ParameterTypes): Returns the parameter types for the
2178 function, and implements a cache that will be useful later when I
2179 do error checking and the semantic analysis on the methods is
2181 (Constructor::GetCallingConvention): Renamed from CallingConvetion
2182 and made a method, optional argument tells whether this is a class
2183 or a structure to apply the `has-this' bit.
2184 (Method::GetCallingConvention): Implement, returns the calling
2186 (Method::Define): Defines the type, a second pass is performed
2187 later to populate the methods.
2189 (Constructor::ParameterTypes): implement a cache similar to the
2190 one on Method::ParameterTypes, useful later when we do semantic
2193 (TypeContainer::EmitMethod): New method. Emits methods.
2195 * expression.cs: Removed MethodGroup class from here.
2197 * parameter.cs (Parameters::GetCallingConvention): new method.
2199 2001-08-21 Miguel de Icaza <miguel@ximian.com>
2201 * class.cs (TypeContainer::Populate): Drop RootContext from the
2204 (Constructor::CallingConvention): Returns the calling convention.
2205 (Constructor::ParameterTypes): Returns the constructor parameter
2208 (TypeContainer::AddConstructor): Keep track of default constructor
2209 and the default static constructor.
2211 (Constructor::) Another class that starts using `public readonly'
2212 instead of properties.
2214 (Constructor::IsDefault): Whether this is a default constructor.
2216 (Field::) use readonly public fields instead of properties also.
2218 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
2219 track of static constructors; If none is used, turn on
2220 BeforeFieldInit in the TypeAttributes.
2222 * cs-parser.jay (opt_argument_list): now the return can be null
2223 for the cases where there are no arguments.
2225 (constructor_declarator): If there is no implicit `base' or
2226 `this', then invoke the default parent constructor.
2228 * modifiers.cs (MethodAttr): New static function maps a set of
2229 modifiers flags into a MethodAttributes enum
2230 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
2231 MethodAttr, TypeAttr to represent the various mappings where the
2233 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
2235 2001-08-19 Miguel de Icaza <miguel@ximian.com>
2237 * parameter.cs (GetParameterInfo): Fix bug where there would be no
2240 * interface.cs (PopulateIndexer): Implemented the code generator
2241 for interface indexers.
2243 2001-08-17 Miguel de Icaza <miguel@ximian.com>
2245 * interface.cs (InterfaceMemberBase): Now we track the new status
2248 (PopulateProperty): Implement property population. Woohoo! Got
2249 Methods and Properties going today.
2251 Removed all the properties for interfaces, and replaced them with
2252 `public readonly' fields.
2254 2001-08-16 Miguel de Icaza <miguel@ximian.com>
2256 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
2257 initialize their hashtables/arraylists only when they are needed
2258 instead of doing this always.
2260 * parameter.cs: Handle refs and out parameters.
2262 * cs-parser.jay: Use an ArrayList to construct the arguments
2263 instead of the ParameterCollection, and then cast that to a
2266 * parameter.cs: Drop the use of ParameterCollection and use
2267 instead arrays of Parameters.
2269 (GetParameterInfo): Use the Type, not the Name when resolving
2272 2001-08-13 Miguel de Icaza <miguel@ximian.com>
2274 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
2275 and instead use public readonly fields.
2277 * class.cs: Put back walking code for type containers.
2279 2001-08-11 Miguel de Icaza <miguel@ximian.com>
2281 * class.cs (MakeConstant): Code to define constants.
2283 * rootcontext.cs (LookupType): New function. Used to locate types
2286 2001-08-08 Miguel de Icaza <miguel@ximian.com>
2288 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
2289 this System.Reflection code is. Kudos to Microsoft
2291 * typemanager.cs: Implement a type cache and avoid loading all
2292 types at boot time. Wrap in LookupType the internals. This made
2293 the compiler so much faster. Wow. I rule!
2295 * driver.cs: Make sure we always load mscorlib first (for
2296 debugging purposes, nothing really important).
2298 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
2299 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
2301 * rootcontext.cs: Lookup types on their namespace; Lookup types
2302 on namespaces that have been imported using the `using' keyword.
2304 * class.cs (TypeContainer::TypeAttr): Virtualize.
2305 (Class::TypeAttr): Return attributes suitable for this bad boy.
2306 (Struct::TypeAttr): ditto.
2307 Handle nested classes.
2308 (TypeContainer::) Remove all the type visiting code, it is now
2309 replaced with the rootcontext.cs code
2311 * rootcontext.cs (GetClassBases): Added support for structs.
2313 2001-08-06 Miguel de Icaza <miguel@ximian.com>
2315 * interface.cs, statement.cs, class.cs, parameter.cs,
2316 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
2317 Drop use of TypeRefs, and use strings instead.
2319 2001-08-04 Miguel de Icaza <miguel@ximian.com>
2323 * class.cs (Struct::Struct): set the SEALED flags after
2324 checking the modifiers.
2325 (TypeContainer::TypeAttr): new property, returns the
2326 TypeAttributes for a class.
2328 * cs-parser.jay (type_list): Oops, list production was creating a
2329 new list of base types.
2331 * rootcontext.cs (StdLib): New property.
2332 (GetInterfaceTypeByName): returns an interface by type name, and
2333 encapsulates error handling here.
2334 (GetInterfaces): simplified.
2335 (ResolveTree): Encapsulated all the tree resolution here.
2336 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
2339 * driver.cs: Add support for --nostdlib, to avoid loading the
2341 (Main): Do not put tree resolution here.
2343 * rootcontext.cs: Beginning of the class resolution.
2345 2001-08-03 Miguel de Icaza <miguel@ximian.com>
2347 * rootcontext.cs: Provide better error reporting.
2349 * cs-parser.jay (interface_base): set our $$ to be interfaces.
2351 * rootcontext.cs (CreateInterface): Handle the case where there
2352 are no parent interfaces.
2354 (CloseTypes): Routine to flush types at the end.
2355 (CreateInterface): Track types.
2356 (GetInterfaces): Returns an array of Types from the list of
2359 * typemanager.c (AddUserType): Mechanism to track user types (puts
2360 the type on the global type hash, and allows us to close it at the
2363 2001-08-02 Miguel de Icaza <miguel@ximian.com>
2365 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
2366 RecordInterface instead.
2368 * cs-parser.jay: Updated to reflect changes above.
2370 * decl.cs (Definition): Keep track of the TypeBuilder type that
2371 represents this type here. Not sure we will use it in the long
2372 run, but wont hurt for now.
2374 * driver.cs: Smaller changes to accomodate the new code.
2376 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
2379 * rootcontext.cs (CreateInterface): New method, used to create
2380 the System.TypeBuilder type for interfaces.
2381 (ResolveInterfaces): new entry point to resolve the interface
2383 (CodeGen): Property, used to keep track of the code generator.
2385 2001-07-26 Miguel de Icaza <miguel@ximian.com>
2387 * cs-parser.jay: Add a second production for delegate_declaration
2390 (enum_body): Put an opt_comma here instead of putting it on
2391 enum_body or enum_member_declarations so we can handle trailing
2392 commas on enumeration members. Gets rid of a shift/reduce.
2394 (type_list): Need a COMMA in the middle.
2396 (indexer_declaration): Tell tokenizer to recognize get/set
2398 * Remove old targets.
2400 * Re-add the parser target.
2402 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2404 * cs-parser.jay: Add precendence rules for a number of operators
2405 ot reduce the number of shift/reduce conflicts in the grammar.
2407 2001-07-17 Miguel de Icaza <miguel@ximian.com>
2409 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
2412 Get rid of old crufty code.
2414 * rootcontext.cs: Use this to keep track of the parsed
2415 representation and the defined types available to the program.
2417 * gen-treedump.cs: adjust for new convention.
2419 * type.cs: Split out the type manager, and the assembly builder
2422 * typemanager.cs: the type manager will live here now.
2424 * cil-codegen.cs: And the code generator here.
2426 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
2428 * makefile: Fixed up for easy making.
2430 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2432 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
2435 (unary_expression): Expand pre_increment_expression and
2436 post_decrement_expression to reduce a shift/reduce.
2438 2001-07-11 Simon Cozens
2440 * cs-tokenizer.cs: Hex numbers should begin with a 0.
2442 Improve allow_keyword_as_indent name.
2444 2001-06-19 Miguel de Icaza <miguel@ximian.com>
2446 * Adjustments for Beta2.
2448 2001-06-13 Miguel de Icaza <miguel@ximian.com>
2450 * decl.cs: Added `Define' abstract method.
2451 (InTransit): new property, used to catch recursive definitions.
2453 * interface.cs: Implement `Define'.
2455 * modifiers.cs: Map Modifiers.constants to
2456 System.Reflection.TypeAttribute flags.
2458 * class.cs: Keep track of types and user-defined types.
2459 (BuilderInit): New method for creating an assembly
2460 (ResolveType): New function to launch the resolution process, only
2461 used by interfaces for now.
2463 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
2464 that are inserted into the name space.
2466 2001-06-08 Miguel de Icaza <miguel@ximian.com>
2468 * ARGH. I have screwed up my tree so many times due to the use of
2469 rsync rather than using CVS. Going to fix this at once.
2471 * driver.cs: Objetify driver. Load assemblies, use assemblies to
2474 2001-06-07 Miguel de Icaza <miguel@ximian.com>
2476 * Experiment successful: Use System.Type rather that our own
2479 2001-05-25 Miguel de Icaza <miguel@ximian.com>
2481 * cs-parser.jay: Removed nsAliases from here.
2483 Use new namespaces, handle `using XXX;'
2485 * namespace.cs: Reimplemented namespace handling, use a recursive
2486 definition of the class. Now we can keep track of using clauses
2487 and catch invalid using clauses.
2489 2001-05-24 Miguel de Icaza <miguel@ximian.com>
2491 * gen-treedump.cs: Adapted for all the renaming.
2493 * expression.cs (Expression): this class now has a Type property
2494 which returns an expression Type.
2496 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
2497 `Type', as this has a different meaning now in the base
2499 2001-05-22 Miguel de Icaza <miguel@ximian.com>
2501 * interface.cs, class.cs: Removed from all the sources the
2502 references to signature computation, as we can not do method
2503 signature computation during the parsing time, as we are not
2504 trying to solve at that point distinguishing:
2508 void a (NS.Blah x) {}
2511 Which depending on the context might be valid or not, as we do not
2512 know if Blah is the same thing as NS.Blah at that point.
2514 * Redid everything so the code uses TypeRefs now instead of
2515 Types. TypeRefs are just temporary type placeholders, that need
2516 to be resolved. They initially have a pointer to a string and the
2517 current scope in which they are used. This is used later by the
2518 compiler to resolve the reference to an actual Type.
2520 * DeclSpace is no longer a CIR.Type, and neither are
2521 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
2522 are all DeclSpaces, but no Types.
2524 * type.cs (TypeRefManager): This implements the TypeRef manager,
2525 which keeps track of all the types that need to be resolved after
2526 the parsing has finished.
2528 2001-05-13 Miguel de Icaza <miguel@ximian.com>
2530 * ARGH. We are going to have to store `foreach' as a class rather
2531 than resolving it, as we need to verify error 1579 after name
2532 resolution. *OR* we could keep a flag that says `This request to
2533 IEnumerator comes from a foreach statement' which we can then use
2534 to generate the error.
2536 2001-05-10 Miguel de Icaza <miguel@ximian.com>
2538 * class.cs (TypeContainer.AddMethod): we now add methods to the
2539 MethodGroup instead of the method hashtable.
2541 * expression.cs: Add MethodGroup abstraction, which gets us one
2542 step closer to the specification in the way we handle method
2545 * cs-parser.jay (primary_expression): qualified_identifier now
2546 tried to match up an identifier to a local variable reference or
2547 to a parameter reference.
2549 current_local_parameters is now a parser global variable that
2550 points to the current parameters for the block, used during name
2553 (property_declaration): Now creates an implicit `value' argument to
2556 2001-05-09 Miguel de Icaza <miguel@ximian.com>
2558 * parameter.cs: Do not use `param' arguments as part of the
2559 signature, per the spec.
2561 2001-05-08 Miguel de Icaza <miguel@ximian.com>
2563 * decl.cs: Base class for classes, structs and interfaces. This
2564 is the "Declaration Space"
2566 * cs-parser.jay: Use CheckDef for checking declaration errors
2567 instead of having one on each function.
2569 * class.cs: Factor out some code for handling error handling in
2570 accordance to the "Declarations" section in the "Basic Concepts"
2571 chapter in the ECMA C# spec.
2573 * interface.cs: Make all interface member classes derive from
2574 InterfaceMemberBase.
2576 2001-05-07 Miguel de Icaza <miguel@ximian.com>
2578 * Many things: all interfaces are parsed and generated in
2579 gen-treedump. Support for member variables, constructors,
2580 destructors, properties, constants is there.
2582 Beginning of the IL backend, but very little done, just there for
2585 2001-04-29 Miguel de Icaza <miguel@ximian.com>
2587 * cs-parser.jay: Fix labeled statement.
2589 * cs-tokenizer.cs (escape): Escape " and ' always.
2590 ref_line, ref_name: keep track of the line/filename as instructed
2591 by #line by the compiler.
2594 2001-04-27 Miguel de Icaza <miguel@ximian.com>
2596 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
2597 to match the values in System.CodeDOM.
2599 Divid renamed to Divide.
2601 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
2603 (Statements.set): remove.
2605 * System.CodeDOM/CodeCatchClause.cs: always have a valid
2608 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
2609 falseStatements always have valid values.
2611 * cs-parser.jay: Use System.CodeDOM now.
