129 * typemanager.cs (ImplementsInterface): interface might be null;
130 Deal with this problem;
132 Also, we do store negative hits on the cache (null values), so use
133 this instead of calling t.GetInterfaces on the type everytime.

687 2001-10-05 Miguel de Icaza <miguel@ximian.com>
689 * expression.cs: Implicity convert the result from UserCast.

756 Create a mapping for method_builders_to_methods ahead of time
757 instead of inside a tight loop.
759 (::RequireMethods): Accept an object as the data to set into the
760 hashtable so we can report interface vs abstract method mismatch.
762 2001-10-03 Miguel de Icaza <miguel@ximian.com>
764 * report.cs: Make all of it static.
766 * rootcontext.cs: Drop object_type and value_type computations, as
767 we have those in the TypeManager anyways.
769 Drop report instance variable too, now it is a global.
771 * driver.cs: Use try/catch on command line handling.
773 Add --probe option to debug the error reporting system with a test
776 * report.cs: Add support for exiting program when a probe
777 condition is reached.
779 2001-10-03 Ravi Pratap <ravi@ximian.com>
781 * expression.cs (Binary::DoNumericPromotions): Fix the case when
782 we do a forcible conversion regardless of type, to check if
783 ForceConversion returns a null.
785 (Binary::error19): Use location to report error.
787 (Unary::error23): Use location here too.
789 * ../errors/cs0019.cs : Check in.
791 * ../errors/cs0023.cs : Check in.
793 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
794 case of a non-null MethodInfo object with a length of 0 !
796 (Binary::ResolveOperator): Flag error if overload resolution fails to find
797 an applicable member - according to the spec :-)
798 Also fix logic to find members in base types.
800 (Unary::ResolveOperator): Same here.
802 (Unary::report23): Change name to error23 and make first argument a TypeContainer
803 as I was getting thoroughly confused between this and error19 :-)
805 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
806 (::FindMostEncompassedType): Implement.
807 (::FindMostEncompassingType): Implement.
808 (::StandardConversionExists): Implement.
810 (UserImplicitCast): Re-vamp. We now need info about most specific
811 source and target types so that we can do the necessary conversions.
813 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
814 mathematical union with no duplicates.
816 2001-10-03 Miguel de Icaza <miguel@ximian.com>
818 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
819 in order from base classes to child classes, so that we can in
820 child classes look up in our parent for method names and
821 attributes (required for handling abstract, virtual, new, override
822 constructs: we need to instrospect our base class, and if we dont
823 populate the classes in order, the introspection might be
824 incorrect. For example, a method could query its parent before
825 the parent has any methods and would determine that the parent has
826 no abstract methods (while it could have had them)).
828 (RootContext::CreateType): Record the order in which we define the
831 2001-10-02 Miguel de Icaza <miguel@ximian.com>
833 * class.cs (TypeContainer::Populate): Also method definitions can
834 fail now, keep track of this.
836 (TypeContainer::FindMembers): Implement support for
837 DeclaredOnly/noDeclaredOnly flag.
839 (Constructor::Emit) Return the ConstructorBuilder.
841 (Method::Emit) Return the MethodBuilder.
842 Check for abstract or virtual methods to be public.
844 * rootcontext.cs (RootContext::CreateType): Register all the
845 abstract methods required for the class to be complete and the
846 interface methods that must be implemented.
848 * cs-parser.jay: Report error 501 (method requires body if it is
849 not marked abstract or extern).
851 * expression.cs (TypeOf::Emit): Implement.
853 * typemanager.cs: runtime_handle_type, new global type.
855 * class.cs (Property::Emit): Generate code for properties.
857 2001-10-02 Ravi Pratap <ravi@ximian.com>
859 * expression.cs (Unary::ResolveOperator): Find operators on base type
860 too - we now conform exactly to the spec.
862 (Binary::ResolveOperator): Same here.
864 * class.cs (Operator::Define): Fix minor quirk in the tests.
866 * ../errors/cs0215.cs : Added.
868 * ../errors/cs0556.cs : Added.
870 * ../errors/cs0555.cs : Added.
872 2001-10-01 Miguel de Icaza <miguel@ximian.com>
874 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
875 single integer which is really efficient
877 2001-10-01 Ravi Pratap <ravi@ximian.com>
879 * expression.cs (Expression::ImplicitUserConversion): Use location
880 even in the case when we are examining True operators.
882 * class.cs (Operator::Define): Perform extensive checks to conform
883 with the rules for operator overloading in the spec.
885 * expression.cs (Expression::ImplicitReferenceConversion): Implement
886 some of the other conversions mentioned in the spec.
888 * typemanager.cs (array_type): New static member for the System.Array built-in
891 (cloneable_interface): For System.ICloneable interface.
893 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
894 we start resolving the tree and populating types.
896 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
898 2001-10-01 Miguel de Icaza <miguel@ximian.com>
900 * expression.cs (Expression::ExprClassFromMemberInfo,
901 Expression::Literalize): Create literal expressions from
902 FieldInfos which are literals.
904 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
905 type casts, because they were wrong. The test suite in tests
908 (ImplicitNumericConversion): ushort to ulong requires a widening
911 Int32 constant to long requires widening cast as well.
913 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
914 for integers because the type on the stack is not i4.
916 2001-09-30 Miguel de Icaza <miguel@ximian.com>
918 * expression.cs (report118): require location argument.
920 * parameter.cs: Do not dereference potential null value.
922 * class.cs: Catch methods that lack the `new' keyword when
923 overriding a name. Report warnings when `new' is used without
924 anything being there to override.
926 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
928 * class.cs: Only add constructor to hashtable if it is non-null
929 (as now constructors can fail on define).
931 (TypeManager, Class, Struct): Take location arguments.
933 Catch field instance initialization in structs as errors.
935 accepting_filter: a new filter for FindMembers that is static so
936 that we dont create an instance per invocation.
938 (Constructor::Define): Catch errors where a struct constructor is
941 * cs-parser.jay: Pass location information for various new
944 * delegate.cs (Delegate): take a location argument.
946 * driver.cs: Do not call EmitCode if there were problesm in the
947 Definition of the types, as many Builders wont be there.
949 * decl.cs (Decl::Decl): Require a location argument.
951 * cs-tokenizer.cs: Handle properly hex constants that can not fit
952 into integers, and find the most appropiate integer for it.
954 * literal.cs: Implement ULongLiteral.
956 * rootcontext.cs: Provide better information about the location of
957 failure when CreateType fails.
959 2001-09-29 Miguel de Icaza <miguel@ximian.com>
961 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
964 * expression.cs (Binary::CheckShiftArguments): Add missing type
966 (Binary::ResolveOperator): Add type to the logical and and logical
967 or, Bitwise And/Or and Exclusive Or code paths, it was missing
970 (Binary::DoNumericPromotions): In the case where either argument
971 is ulong (and most signed types combined with ulong cause an
972 error) perform implicit integer constant conversions as well.
974 2001-09-28 Miguel de Icaza <miguel@ximian.com>
976 * expression.cs (UserImplicitCast): Method should always be
978 (Invocation::BetterConversion): Simplified test for IntLiteral.
980 (Expression::ImplicitNumericConversion): Split this routine out.
981 Put the code that performs implicit constant integer conversions
984 (Expression::Resolve): Become a wrapper around DoResolve so we can
985 check eclass and type being set after resolve.
987 (Invocation::Badness): Remove this dead function
989 (Binary::ResolveOperator): Do not compute the expensive argumnets
990 unless we have a union for it.
992 (Probe::Emit): Is needs to do an isinst and then
993 compare against null.
995 (::CanConvert): Added Location argument. If the Location argument
996 is null (Location.Null), then we do not report errors. This is
997 used by the `probe' mechanism of the Explicit conversion. We do
998 not want to generate an error for something that the user
999 explicitly requested to be casted. But the pipeline for an
1000 explicit cast first tests for potential implicit casts.
1002 So for now, if the Location is null, it means `Probe only' to
1003 avoid adding another argument. Might have to revise this
1006 (ClassCast): New class used to type cast objects into arbitrary
1007 classes (used in Explicit Reference Conversions).
1009 Implement `as' as well.
1011 Reverted all the patches from Ravi below: they were broken:
1013 * The use of `level' as a mechanism to stop recursive
1014 invocations is wrong. That was there just to catch the
1015 bug with a strack trace but not as a way of addressing
1018 To fix the problem we have to *understand* what is going
1019 on and the interactions and come up with a plan, not
1020 just get things going.
1022 * The use of the type conversion cache that I proposed
1023 last night had an open topic: How does this work across
1024 protection domains. A user defined conversion might not
1025 be public in the location where we are applying the
1026 conversion, a different conversion might be selected
1027 (ie, private A->B (better) but public B->A (worse),
1028 inside A, A->B applies, but outside it, B->A will
1031 * On top of that (ie, even if the above is solved),
1032 conversions in a cache need to be abstract. Ie, `To
1033 convert from an Int to a Short use an OpcodeCast', not
1034 `To convert from an Int to a Short use the OpcodeCast on
1035 the variable 5' (which is what this patch was doing).
1037 2001-09-28 Ravi Pratap <ravi@ximian.com>
1039 * expression.cs (Invocation::ConversionExists): Re-write to use
1040 the conversion cache
1042 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
1043 cache all conversions done, not just user-defined ones.
1045 (Invocation::BetterConversion): The real culprit. Use ConversionExists
1046 to determine if a conversion exists instead of acutually trying to
1047 perform the conversion. It's faster too.
1049 (Expression::ConvertExplicit): Modify to use ConversionExists to check
1050 and only then attempt the implicit conversion.
1052 2001-09-28 Ravi Pratap <ravi@ximian.com>
1054 * expression.cs (ConvertImplicit): Use a cache for conversions
1055 already found. Check level of recursion and bail out if necessary.
1057 2001-09-28 Miguel de Icaza <miguel@ximian.com>
1059 * typemanager.cs (string_concat_string_string, string_concat_object_object):
1060 Export standard methods that we expect for string operations.
1062 * statement.cs (Block::UsageWarning): Track usage of variables and
1063 report the errors for not used variables.
1065 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
1068 2001-09-27 Miguel de Icaza <miguel@ximian.com>
1070 * codegen.cs: remove unnneded code
1072 * expression.cs: Removed BuiltinTypeAccess class
1074 Fix the order in which implicit conversions are
1077 The previous fixed dropped support for boxed conversions (adding a
1078 test to the test suite now)
1080 (UserImplicitCast::CanConvert): Remove test for source being null,
1081 that code is broken. We should not feed a null to begin with, if
1082 we do, then we should track the bug where the problem originates
1083 and not try to cover it up here.
1085 Return a resolved expression of type UserImplicitCast on success
1086 rather than true/false. Ravi: this is what I was talking about,
1087 the pattern is to use a static method as a "constructor" for
1090 Also, do not create arguments until the very last minute,
1091 otherwise we always create the arguments even for lookups that
1092 will never be performed.
1094 (UserImplicitCast::Resolve): Eliminate, objects of type
1095 UserImplicitCast are born in a fully resolved state.
1097 * typemanager.cs (InitCoreTypes): Init also value_type
1100 * expression.cs (Cast::Resolve): First resolve the child expression.
1102 (LValue): Add new method AddressOf to be used by
1105 Change the argument of Store to take an EmitContext instead of an
1106 ILGenerator, because things like FieldExpr need to be able to call
1107 their children expression to generate the instance code.
1109 (Expression::Error, Expression::Warning): Sugar functions for
1112 (Expression::MemberLookup): Accept a TypeContainer instead of a
1113 Report as the first argument.
1115 (Expression::ResolvePrimary): Killed. I still want to improve
1116 this as currently the code is just not right.
1118 (Expression::ResolveMemberAccess): Simplify, but it is still
1121 (Unary::Resolve): Catch errors in AddressOf operators.
1123 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
1124 index to a byte for the short-version, or the compiler will choose
1125 the wrong Emit call, which generates the wrong data.
1127 (ParameterReference::Emit, ::Store): same.
1129 (FieldExpr::AddressOf): Implement.
1131 * typemanager.cs: TypeManager: made public variable instead of
1134 * driver.cs: document --fatal.
1136 * report.cs (ErrorMessage, WarningMessage): new names for the old
1137 Error and Warning classes.
1139 * cs-parser.jay (member_access): Turn built-in access to types
1140 into a normal simplename
1142 2001-09-27 Ravi Pratap <ravi@ximian.com>

1145 with q being null, since this was introducing a bug.
1147 * expression.cs (ConvertImplicit): Do built-in conversions first.
1149 2001-09-27 Ravi Pratap <ravi@ximian.com>
1151 * expression.cs (UserImplicitCast::Resolve): Fix bug.
1153 2001-09-27 Ravi Pratap <ravi@ximian.com>
1155 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
1156 I had introduced long ago (what's new ?).
1158 * expression.cs (UserImplicitCast::CanConvert): Static method to do
1159 the work of all the checking.
1160 (ConvertImplicit): Call CanConvert and only then create object if necessary.
1161 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
1163 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
1164 that is the right way.
1166 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
1167 overloading resolution. Use everywhere instead of cutting and pasting code.
1169 (Binary::ResolveOperator): Use MakeUnionSet.
1171 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
1172 we have to convert to bool types. Not complete yet.

1176 * typemanager.cs (TypeManager::CSharpName): support ushort.
1178 * expression.cs (Expression::TryImplicitIntConversion): Attempts
1179 to provide an expression that performsn an implicit constant int
1180 conversion (section 6.1.6).
1181 (Expression::ConvertImplicitRequired): Reworked to include
1182 implicit constant expression conversions.
1184 (Expression::ConvertNumericExplicit): Finished.
1186 (Invocation::Emit): If InstanceExpression is null, then it means
1187 that we perform a call on this.
1189 2001-09-26 Miguel de Icaza <miguel@ximian.com>
1191 * expression.cs (Unary::Emit): Remove some dead code.
1192 (Probe): Implement Resolve and Emit for `is'.
1193 (Expression::ConvertImplicitRequired): Attempt to do constant
1194 expression conversions here. Maybe should be moved to
1195 ConvertImplicit, but I am not sure.
1196 (Expression::ImplicitLongConstantConversionPossible,
1197 Expression::ImplicitIntConstantConversionPossible): New functions
1198 that tell whether is it possible to apply an implicit constant
1199 expression conversion.
1201 (ConvertNumericExplicit): Started work on explicit numeric
1204 * cs-parser.jay: Update operator constants.
1206 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
1207 (Parameters::GetSignature): Hook up VerifyArgs here.
1208 (Parameters::VerifyArgs): Verifies that no two arguments have the
1211 * class.cs (Operator): Update the operator names to reflect the
1212 ones that the spec expects (as we are just stringizing the
1215 * expression.cs (Unary::ResolveOperator): Fix bug: Use
1216 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
1217 previous usage did only work for our methods.
1218 (Expression::ConvertImplicit): Handle decimal implicit numeric
1219 conversions as well.
1220 (Expression::InternalTypeConstructor): Used to invoke constructors
1221 on internal types for default promotions.
1223 (Unary::Emit): Implement special handling for the pre/post
1224 increment/decrement for overloaded operators, as they need to have
1225 the same semantics as the other operators.
1227 (Binary::ResolveOperator): ditto.
1228 (Invocation::ConversionExists): ditto.
1229 (UserImplicitCast::Resolve): ditto.
1231 2001-09-26 Ravi Pratap <ravi@ximian.com>
1233 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded
1234 operator, return after emitting body. Regression tests pass again !
1236 * expression.cs (ConvertImplicit): Take TypeContainer as first argument
1237 (Unary::ForceConversion, Binary::ForceConversion): Ditto.
1238 (Invocation::OverloadResolve): Ditto.
1239 (Invocation::BetterFunction, BetterConversion, ConversionExists): Ditto.
1241 * everywhere : update calls to the above methods accordingly.
1243 2001-09-26 Miguel de Icaza <miguel@ximian.com>
1245 * assign.cs (Assign): Make it inherit from ExpressionStatement.
1247 * expression.cs (ExpressionStatement): New base class used for
1248 expressions that can appear in statements, so that we can provide
1249 an alternate path to generate expression that do not leave a value
1252 (Expression::Emit, and all the derivatives): We no longer return
1253 whether a value is left on the stack or not. Every expression
1254 after being emitted leaves a single value on the stack.
1256 * codegen.cs (EmitContext::EmitStatementExpression): Use the
1257 facilties of ExpressionStatement if possible.
1259 * cs-parser.jay: Update statement_expression.

1270 (Unary::ResolveOperator): Ditto.
1272 * expression.cs (Invocation::ConversionExists): Correct the member lookup
1273 to find "op_Implicit", not "implicit" ;-)
1274 (UserImplicitCast): New class to take care of user-defined implicit conversions.

1280 (ConvertImplicit): Do user-defined conversion if it exists.
1282 2001-09-24 Miguel de Icaza <miguel@ximian.com>
1284 * assign.cs: track location.
1285 (Resolve): Use implicit conversions on assignment.
1287 * literal.cs: Oops. Not good, Emit of short access values should

1290 * expression.cs (Unary::Emit): Emit code for -expr.
1292 (Unary::ResolveOperator): Handle `Substract' for non-constants
1293 (substract from zero from the non-constants).

1328 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
1329 Also take an additional TypeContainer argument.
1331 * All over : Pass in TypeContainer as argument to OverloadResolve.
1333 * typemanager.cs (CSharpName): Update to check for the string type and return
1336 * expression.cs (Invocation::FullMethodDesc): New static method to return a string fully describing
1339 2001-09-21 Ravi Pratap <ravi@ximian.com>
1341 * expression.cs (Invocation::OverloadResolve): Re-write to conform more to the spec.
1342 (Invocation::BetterFunction): Implement.
1343 (Invocation::BetterConversion): Implement.
1344 (Invocation::ConversionExists): Skeleton, no implementation yet.
1346 Okay, things work fine !
1348 2001-09-21 Miguel de Icaza <miguel@ximian.com>
1350 * typemanager.cs: declare and load enum_type, delegate_type and
1353 * expression.cs (Expression::Emit): Now emit returns a value that
1354 tells whether a value is left on the stack or not. This strategy
1355 might be reveted tomorrow with a mechanism that would address
1356 multiple assignments.
1357 (Expression::report118): Utility routine to report mismatches on
1360 (Unary::Report23): Report impossible type/operator combination
1363 (Unary::IsIncrementableNumber): Whether the type can be
1364 incremented or decremented with add.

1397 * expression.cs (SimpleName::ResolveSimpleName): Error if we can
1400 * cs-parser.jay (QualifierIdentifier): Pass location to SimpleName
1403 * statement.cs (Block::EmitMeta): Reuse the count across all the variables,
1404 otherwise nested blocks end up with the same index.
1406 * codegen.cs (CodeGen::EmitTopBlock): Pass initial sequence
1408 * expression.cs: Instead of having FIXMEs in the Resolve
1409 functions, throw exceptions so it is obvious that we are facing a
1412 * cs-parser.jay (invocation_expression): Pass Location information.
1414 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
1415 Use a basename for those routines because .NET does not like paths

1427 * expression.cs (Unary::ResolveOperator): return the child
1428 expression for expressions which are just +expr.

1432 expression conversions'.

1461 * class.cs (Operator::Define): Fix a small bug for the case when we have
1464 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
1465 for the inbuilt operators. Only overloading works for now ;-)
1467 2001-09-18 Miguel de Icaza <miguel@ximian.com>
1469 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
1470 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

1485 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
1486 the last instruction contains a return opcode to avoid generating
1487 the last `ret' instruction (this generates correct code, and it is
1488 nice to pass the peverify output).
1490 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
1491 initializer for static and instance variables.
1492 (Constructor::Emit): Allow initializer to be null in the case of
1493 static constructors. Only emit initializer for instance
1496 (TypeContainer::FindMembers): Return a null array if there are no

1500 scanning that for operators (or tried to access null variables before).
1502 * assign.cs (Assign::Emit): Handle instance and static fields.
1506 * driver.cs: Stop compilation if there are parse errors.
1508 * cs-parser.jay (constructor_declaration): Provide default base

1511 initializers if none was specified.
1512 Catch the fact that constructors should not have parameters.
1514 * class.cs: Do not emit parent class initializers for static
1515 constructors, that should be flagged as an error.
1517 2001-09-18 Ravi Pratap <ravi@ximian.com>
1519 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
1520 Move back code into TypeContainer::Populate.

1549 (Expression::MemberLookup): Provide a version that allows to
1550 specify the MemberTypes and BindingFlags.
1552 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
1553 so it was not fetching variable information from outer blocks.
1555 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
1556 Beforefieldinit as it was buggy.
1558 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200

1655 * modifiers.cs: Do not use `parent', instead use the real type
1656 container to evaluate permission settings.

1659 have to cope with the
1661 2001-09-14 Ravi Pratap <ravi@ximian.com>
1663 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
1664 FamORAssem, not FamANDAssem.

1668 * driver.cs: Added --parse option that only parses its input files
1671 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
1672 incorrect. IsTopLevel is not used to tell whether an object is
1673 root_types or not (that can be achieved by testing this ==
1674 root_types). But to see if this is a top-level *class* (not
1675 necessarly our "toplevel" container).
1677 2001-09-14 Ravi Pratap <ravi@ximian.com>
1679 * enum.cs (Enum::Define): Modify to call the Lookup method on the
1680 parent instead of a direct call to GetType.

1684 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
1685 Modifiers.TypeAttr. This should just be a call to that method.
1687 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
1688 object so that we can determine if we are top-level or not.
1690 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
1693 * enum.cs (Enum::Define): Ditto.
1695 * modifiers.cs (FieldAttr): Re-write.

1698 (TypeContainer::HaveStaticConstructor): New property to provide access
1699 to precisely that info.
1701 * modifiers.cs (MethodAttr): Re-write.
1702 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
1704 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent

1707 2001-09-13 Miguel de Icaza <miguel@ximian.com>
1709 * expression.cs (MemberLookup): Fruitless attempt to lookup
1710 constructors. Maybe I need to emit default constructors? That
1711 might be it (currently .NET emits this for me automatically).
1712 (Invocation::OverloadResolve): Cope with Arguments == null.
1713 (Invocation::EmitArguments): new function, shared by the new

1735 objects that we might have around.
1737 (Populate): Only initialize method_builders_to_methods once.
1739 * expression.cs (PropertyExpr): Initialize type from the
1742 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

1747 (Binary::ResolveOperator): Set the return type to boolean for
1748 comparission operators
1750 * typemanager.cs: Remove debugging print code.
1752 (Invocation::Resolve): resolve type.
1754 * class.cs: Allocate a MemberInfo of the correct size, as the code
1755 elsewhere depends on the test to reflect the correct contents.
1757 (Method::) Keep track of parameters, due to System.Reflection holes
1759 (TypeContainer::Populate): Keep track of MethodBuilders to Method
1762 (TypeContainer::FindMembers): Use ArrayList and then copy an array
1763 of the exact size and return that.
1765 (Class::LookupMethodByBuilder): New function that maps
1766 MethodBuilders to its methods. Required to locate the information
1767 on methods because System.Reflection bit us again.
1769 * support.cs: New file, contains an interface ParameterData and
1770 two implementations: ReflectionParameters and InternalParameters
1771 used to access Parameter information. We will need to grow this
1774 * expression.cs (Invocation::GetParameterData): implement a cache
1775 and a wrapper around the ParameterData creation for methods.
1776 (Invocation::OverloadResolve): Use new code.
1778 2001-09-13 Ravi Pratap <ravi@ximian.com>

1832 2001-09-12 Ravi Pratap <ravi@ximian.com>
1834 * class.cs (TypeContainer::FindMembers): Method which does exactly
1835 what Type.FindMembers does, only we don't have to use reflection. No

1839 typecontainer objects as we need to get at them.
1840 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

1868 (Property::Define): Ditto.

1882 addOn_ and removeOn_
1884 * genericparser.cs (GenericParser::error): Overloaded method to handle the case

2290 (indexer_declarator): Implement actions.
2291 (parsing_indexer): New local boolean used to keep track of whether

2355 compiling corlib.dll)
2357 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
2358 on Expression Classification. Now all expressions have a method
2359 `Resolve' and a method `Emit'.
2361 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
2362 generation from working. Also add some temporary debugging
2365 2001-08-24 Miguel de Icaza <miguel@ximian.com>
2367 * codegen.cs: Lots of code generation pieces. This is only the
2368 beginning, will continue tomorrow with more touches of polish. We

2405 and made a method, optional argument tells whether this is a class
2406 or a structure to apply the `has-this' bit.

2439 (Field::) use readonly public fields instead of properties also.
2441 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
2442 track of static constructors; If none is used, turn on
2443 BeforeFieldInit in the TypeAttributes.
2445 * cs-parser.jay (opt_argument_list): now the return can be null
2446 for the cases where there are no arguments.
2448 (constructor_declarator): If there is no implicit `base' or

2451 * modifiers.cs (MethodAttr): New static function maps a set of
2452 modifiers flags into a MethodAttributes enum
2453 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
2454 MethodAttr, TypeAttr to represent the various mappings where the
2456 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'

2518 * driver.cs: Make sure we always load mscorlib first (for
2519 debugging purposes, nothing really important).
2521 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
2522 have moved to `CSC' rather than `CIR'. Oh man! The confussion!

2589 RecordInterface instead.
2591 * cs-parser.jay: Updated to reflect changes above.
2593 * decl.cs (Definition): Keep track of the TypeBuilder type that
2594 represents this type here. Not sure we will use it in the long

2704 * cs-parser.jay: Removed nsAliases from here.
2706 Use new namespaces, handle `using XXX;'
2708 * namespace.cs: Reimplemented namespace handling, use a recursive
2709 definition of the class. Now we can keep track of using clauses
2710 and catch invalid using clauses.
2712 2001-05-24 Miguel de Icaza <miguel@ximian.com>
2714 * gen-treedump.cs: Adapted for all the renaming.
2716 * expression.cs (Expression): this class now has a Type property
2717 which returns an expression Type.
2719 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
2720 `Type', as this has a different meaning now in the base
2722 2001-05-22 Miguel de Icaza <miguel@ximian.com>
2724 * interface.cs, class.cs: Removed from all the sources the
2725 references to signature computation, as we can not do method
2726 signature computation during the parsing time, as we are not
2727 trying to solve at that point distinguishing:
2731 void a (NS.Blah x) {}
2734 Which depending on the context might be valid or not, as we do not
2735 know if Blah is the same thing as NS.Blah at that point.
2737 * Redid everything so the code uses TypeRefs now instead of
2738 Types. TypeRefs are just temporary type placeholders, that need
2739 to be resolved. They initially have a pointer to a string and the
2740 current scope in which they are used. This is used later by the
2741 compiler to resolve the reference to an actual Type.
2743 * DeclSpace is no longer a CIR.Type, and neither are
2744 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
2745 are all DeclSpaces, but no Types.
2747 * type.cs (TypeRefManager): This implements the TypeRef manager,
2748 which keeps track of all the types that need to be resolved after
2749 the parsing has finished.
2751 2001-05-13 Miguel de Icaza <miguel@ximian.com>
2753 * ARGH. We are going to have to store `foreach' as a class rather
2754 than resolving it, as we need to verify error 1579 after name
2755 resolution. *OR* we could keep a flag that says `This request to
2756 IEnumerator comes from a foreach statement' which we can then use
2757 to generate the error.
2759 2001-05-10 Miguel de Icaza <miguel@ximian.com>
2761 * class.cs (TypeContainer.AddMethod): we now add methods to the
2762 MethodGroup instead of the method hashtable.
2764 * expression.cs: Add MethodGroup abstraction, which gets us one
2765 step closer to the specification in the way we handle method
2768 * cs-parser.jay (primary_expression): qualified_identifier now
2769 tried to match up an identifier to a local variable reference or
2770 to a parameter reference.
2772 current_local_parameters is now a parser global variable that
2773 points to the current parameters for the block, used during name
2776 (property_declaration): Now creates an implicit `value' argument to
2779 2001-05-09 Miguel de Icaza <miguel@ximian.com>
2781 * parameter.cs: Do not use `param' arguments as part of the
2782 signature, per the spec.
2784 2001-05-08 Miguel de Icaza <miguel@ximian.com>
2786 * decl.cs: Base class for classes, structs and interfaces. This
2787 is the "Declaration Space"
2789 * cs-parser.jay: Use CheckDef for checking declaration errors
2790 instead of having one on each function.
2792 * class.cs: Factor out some code for handling error handling in
2793 accordance to the "Declarations" section in the "Basic Concepts"
2794 chapter in the ECMA C# spec.
2796 * interface.cs: Make all interface member classes derive from
2797 InterfaceMemberBase.
2799 2001-05-07 Miguel de Icaza <miguel@ximian.com>
2801 * Many things: all interfaces are parsed and generated in
2802 gen-treedump. Support for member variables, constructors,
2803 destructors, properties, constants is there.
2805 Beginning of the IL backend, but very little done, just there for
2808 2001-04-29 Miguel de Icaza <miguel@ximian.com>
2810 * cs-parser.jay: Fix labeled statement.
2812 * cs-tokenizer.cs (escape): Escape " and ' always.
2813 ref_line, ref_name: keep track of the line/filename as instructed
2814 by #line by the compiler.
2817 2001-04-27 Miguel de Icaza <miguel@ximian.com>
2819 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
2820 to match the values in System.CodeDOM.
2822 Divid renamed to Divide.
2824 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
2826 (Statements.set): remove.
2828 * System.CodeDOM/CodeCatchClause.cs: always have a valid
2831 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
2832 falseStatements always have valid values.
2834 * cs-parser.jay: Use System.CodeDOM now.
