555 * expression.cs: Implicity convert the result from UserCast.

630 * report.cs: Make all of it static.
632 * rootcontext.cs: Drop object_type and value_type computations, as

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

685 in order from base classes to child classes, so that we can in
686 child classes look up in our parent for method names and
687 attributes (required for handling abstract, virtual, new, override
688 constructs: we need to instrospect our base class, and if we dont
689 populate the classes in order, the introspection might be
690 incorrect. For example, a method could query its parent before
691 the parent has any methods and would determine that the parent has
692 no abstract methods (while it could have had them)).

748 * class.cs (Operator::Define): Perform extensive checks to conform
749 with the rules for operator overloading in the spec.
751 * expression.cs (Expression::ImplicitReferenceConversion): Implement
752 some of the other conversions mentioned in the spec.
754 * typemanager.cs (array_type): New static member for the System.Array built-in
757 (cloneable_interface): For System.ICloneable interface.
759 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
760 we start resolving the tree and populating types.
762 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
764 2001-10-01 Miguel de Icaza <miguel@ximian.com>
766 * expression.cs (Expression::ExprClassFromMemberInfo,
767 Expression::Literalize): Create literal expressions from
768 FieldInfos which are literals.
770 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
771 type casts, because they were wrong. The test suite in tests
774 (ImplicitNumericConversion): ushort to ulong requires a widening
777 Int32 constant to long requires widening cast as well.
779 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
780 for integers because the type on the stack is not i4.
782 2001-09-30 Miguel de Icaza <miguel@ximian.com>
784 * expression.cs (report118): require location argument.
786 * parameter.cs: Do not dereference potential null value.
788 * class.cs: Catch methods that lack the `new' keyword when
789 overriding a name. Report warnings when `new' is used without
790 anything being there to override.
792 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
794 * class.cs: Only add constructor to hashtable if it is non-null
795 (as now constructors can fail on define).
797 (TypeManager, Class, Struct): Take location arguments.
799 Catch field instance initialization in structs as errors.
801 accepting_filter: a new filter for FindMembers that is static so
802 that we dont create an instance per invocation.
804 (Constructor::Define): Catch errors where a struct constructor is
807 * cs-parser.jay: Pass location information for various new
810 * delegate.cs (Delegate): take a location argument.
812 * driver.cs: Do not call EmitCode if there were problesm in the
813 Definition of the types, as many Builders wont be there.
815 * decl.cs (Decl::Decl): Require a location argument.
817 * cs-tokenizer.cs: Handle properly hex constants that can not fit
818 into integers, and find the most appropiate integer for it.
820 * literal.cs: Implement ULongLiteral.
822 * rootcontext.cs: Provide better information about the location of
823 failure when CreateType fails.
825 2001-09-29 Miguel de Icaza <miguel@ximian.com>
827 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
830 * expression.cs (Binary::CheckShiftArguments): Add missing type
832 (Binary::ResolveOperator): Add type to the logical and and logical
833 or, Bitwise And/Or and Exclusive Or code paths, it was missing
836 (Binary::DoNumericPromotions): In the case where either argument
837 is ulong (and most signed types combined with ulong cause an
838 error) perform implicit integer constant conversions as well.
840 2001-09-28 Miguel de Icaza <miguel@ximian.com>
842 * expression.cs (UserImplicitCast): Method should always be
844 (Invocation::BetterConversion): Simplified test for IntLiteral.
846 (Expression::ImplicitNumericConversion): Split this routine out.
847 Put the code that performs implicit constant integer conversions
850 (Expression::Resolve): Become a wrapper around DoResolve so we can
851 check eclass and type being set after resolve.
853 (Invocation::Badness): Remove this dead function
855 (Binary::ResolveOperator): Do not compute the expensive argumnets
856 unless we have a union for it.
858 (Probe::Emit): Is needs to do an isinst and then
859 compare against null.
861 (::CanConvert): Added Location argument. If the Location argument
862 is null (Location.Null), then we do not report errors. This is
863 used by the `probe' mechanism of the Explicit conversion. We do
864 not want to generate an error for something that the user
865 explicitly requested to be casted. But the pipeline for an
866 explicit cast first tests for potential implicit casts.
868 So for now, if the Location is null, it means `Probe only' to
869 avoid adding another argument. Might have to revise this
872 (ClassCast): New class used to type cast objects into arbitrary
873 classes (used in Explicit Reference Conversions).
875 Implement `as' as well.
877 Reverted all the patches from Ravi below: they were broken:
879 * The use of `level' as a mechanism to stop recursive
880 invocations is wrong. That was there just to catch the
881 bug with a strack trace but not as a way of addressing
884 To fix the problem we have to *understand* what is going
885 on and the interactions and come up with a plan, not
886 just get things going.
888 * The use of the type conversion cache that I proposed
889 last night had an open topic: How does this work across
890 protection domains. A user defined conversion might not
891 be public in the location where we are applying the
892 conversion, a different conversion might be selected
893 (ie, private A->B (better) but public B->A (worse),
894 inside A, A->B applies, but outside it, B->A will
897 * On top of that (ie, even if the above is solved),
898 conversions in a cache need to be abstract. Ie, `To
899 convert from an Int to a Short use an OpcodeCast', not
900 `To convert from an Int to a Short use the OpcodeCast on
901 the variable 5' (which is what this patch was doing).
903 2001-09-28 Ravi Pratap <ravi@ximian.com>
905 * expression.cs (Invocation::ConversionExists): Re-write to use
908 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
909 cache all conversions done, not just user-defined ones.
911 (Invocation::BetterConversion): The real culprit. Use ConversionExists
912 to determine if a conversion exists instead of acutually trying to
913 perform the conversion. It's faster too.
915 (Expression::ConvertExplicit): Modify to use ConversionExists to check
916 and only then attempt the implicit conversion.
918 2001-09-28 Ravi Pratap <ravi@ximian.com>
920 * expression.cs (ConvertImplicit): Use a cache for conversions
921 already found. Check level of recursion and bail out if necessary.
923 2001-09-28 Miguel de Icaza <miguel@ximian.com>
925 * typemanager.cs (string_concat_string_string, string_concat_object_object):
926 Export standard methods that we expect for string operations.
928 * statement.cs (Block::UsageWarning): Track usage of variables and
929 report the errors for not used variables.
931 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
934 2001-09-27 Miguel de Icaza <miguel@ximian.com>
936 * codegen.cs: remove unnneded code
938 * expression.cs: Removed BuiltinTypeAccess class
940 Fix the order in which implicit conversions are
943 The previous fixed dropped support for boxed conversions (adding a
944 test to the test suite now)
946 (UserImplicitCast::CanConvert): Remove test for source being null,
947 that code is broken. We should not feed a null to begin with, if
948 we do, then we should track the bug where the problem originates
949 and not try to cover it up here.
951 Return a resolved expression of type UserImplicitCast on success
952 rather than true/false. Ravi: this is what I was talking about,
953 the pattern is to use a static method as a "constructor" for
956 Also, do not create arguments until the very last minute,
957 otherwise we always create the arguments even for lookups that
958 will never be performed.
960 (UserImplicitCast::Resolve): Eliminate, objects of type
961 UserImplicitCast are born in a fully resolved state.
963 * typemanager.cs (InitCoreTypes): Init also value_type
966 * expression.cs (Cast::Resolve): First resolve the child expression.
968 (LValue): Add new method AddressOf to be used by
971 Change the argument of Store to take an EmitContext instead of an
972 ILGenerator, because things like FieldExpr need to be able to call
973 their children expression to generate the instance code.
975 (Expression::Error, Expression::Warning): Sugar functions for
978 (Expression::MemberLookup): Accept a TypeContainer instead of a
979 Report as the first argument.
981 (Expression::ResolvePrimary): Killed. I still want to improve
982 this as currently the code is just not right.
984 (Expression::ResolveMemberAccess): Simplify, but it is still
987 (Unary::Resolve): Catch errors in AddressOf operators.
989 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
990 index to a byte for the short-version, or the compiler will choose
991 the wrong Emit call, which generates the wrong data.
993 (ParameterReference::Emit, ::Store): same.
995 (FieldExpr::AddressOf): Implement.
997 * typemanager.cs: TypeManager: made public variable instead of
1000 * driver.cs: document --fatal.
1002 * report.cs (ErrorMessage, WarningMessage): new names for the old
1003 Error and Warning classes.
1005 * cs-parser.jay (member_access): Turn built-in access to types
1006 into a normal simplename
1008 2001-09-27 Ravi Pratap <ravi@ximian.com>
1010 * expression.cs (Invocation::BetterConversion): Fix to cope
1011 with q being null, since this was introducing a bug.

1024 * expression.cs (UserImplicitCast::CanConvert): Static method to do
1025 the work of all the checking.
1026 (ConvertImplicit): Call CanConvert and only then create object if necessary.
1027 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
1029 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
1030 that is the right way.
1032 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
1033 overloading resolution. Use everywhere instead of cutting and pasting code.
1035 (Binary::ResolveOperator): Use MakeUnionSet.
1037 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
1038 we have to convert to bool types. Not complete yet.
1040 2001-09-27 Miguel de Icaza <miguel@ximian.com>
1042 * typemanager.cs (TypeManager::CSharpName): support ushort.
1044 * expression.cs (Expression::TryImplicitIntConversion): Attempts
1045 to provide an expression that performsn an implicit constant int
1046 conversion (section 6.1.6).
1047 (Expression::ConvertImplicitRequired): Reworked to include
1048 implicit constant expression conversions.
1050 (Expression::ConvertNumericExplicit): Finished.
1052 (Invocation::Emit): If InstanceExpression is null, then it means
1053 that we perform a call on this.

1057 * expression.cs (Unary::Emit): Remove some dead code.
1058 (Probe): Implement Resolve and Emit for `is'.
1059 (Expression::ConvertImplicitRequired): Attempt to do constant
1060 expression conversions here. Maybe should be moved to
1061 ConvertImplicit, but I am not sure.
1062 (Expression::ImplicitLongConstantConversionPossible,
1063 Expression::ImplicitIntConstantConversionPossible): New functions
1064 that tell whether is it possible to apply an implicit constant
1065 expression conversion.

1077 * class.cs (Operator): Update the operator names to reflect the
1078 ones that the spec expects (as we are just stringizing the
1081 * expression.cs (Unary::ResolveOperator): Fix bug: Use
1082 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
1083 previous usage did only work for our methods.
1084 (Expression::ConvertImplicit): Handle decimal implicit numeric
1085 conversions as well.
1086 (Expression::InternalTypeConstructor): Used to invoke constructors
1087 on internal types for default promotions.
1089 (Unary::Emit): Implement special handling for the pre/post
1090 increment/decrement for overloaded operators, as they need to have
1091 the same semantics as the other operators.
1093 (Binary::ResolveOperator): ditto.
1094 (Invocation::ConversionExists): ditto.
1095 (UserImplicitCast::Resolve): ditto.

1111 * assign.cs (Assign): Make it inherit from ExpressionStatement.
1113 * expression.cs (ExpressionStatement): New base class used for
1114 expressions that can appear in statements, so that we can provide
1115 an alternate path to generate expression that do not leave a value
1118 (Expression::Emit, and all the derivatives): We no longer return
1119 whether a value is left on the stack or not. Every expression
1120 after being emitted leaves a single value on the stack.
1122 * codegen.cs (EmitContext::EmitStatementExpression): Use the
1123 facilties of ExpressionStatement if possible.
1125 * cs-parser.jay: Update statement_expression.

1146 (ConvertImplicit): Do user-defined conversion if it exists.
1148 2001-09-24 Miguel de Icaza <miguel@ximian.com>
1150 * assign.cs: track location.
1151 (Resolve): Use implicit conversions on assignment.
1153 * literal.cs: Oops. Not good, Emit of short access values should

1194 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
1195 Also take an additional TypeContainer argument.

1214 2001-09-21 Miguel de Icaza <miguel@ximian.com>
1216 * typemanager.cs: declare and load enum_type, delegate_type and
1219 * expression.cs (Expression::Emit): Now emit returns a value that
1220 tells whether a value is left on the stack or not. This strategy
1221 might be reveted tomorrow with a mechanism that would address
1222 multiple assignments.
1223 (Expression::report118): Utility routine to report mismatches on
1226 (Unary::Report23): Report impossible type/operator combination
1229 (Unary::IsIncrementableNumber): Whether the type can be

1275 functions, throw exceptions so it is obvious that we are facing a
1278 * cs-parser.jay (invocation_expression): Pass Location information.
1280 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
1281 Use a basename for those routines because .NET does not like paths

1287 2001-09-19 Miguel de Icaza <miguel@ximian.com>

1293 * expression.cs (Unary::ResolveOperator): return the child
1294 expression for expressions which are just +expr.

1301 (IntLiteral): export the `Value' of the intliteral.

1307 * class.cs (Operator::Define): Change the methodname prefix to 'op_'
1308 instead of 'Operator'
1310 * expression.cs (Binary::ResolveOperator): Update accordingly.
1311 (Unary::Operator): Change names to 'Add' and 'Subtract' instead 'Plus'
1314 * cs-parser.jay (unary_expression): Update to use the new names.

1318 * expression.cs (Unary::Resolve): Implement.
1319 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded

1324 (Unary::OperName): Implement.
1325 (Unary::ForceConversion): Copy and Paste !
1327 * class.cs (Operator::Define): Fix a small bug for the case when we have
1330 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
1331 for the inbuilt operators. Only overloading works for now ;-)

1349 (FieldExpr::Emit): Implement.
1351 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
1352 the last instruction contains a return opcode to avoid generating
1353 the last `ret' instruction (this generates correct code, and it is
1354 nice to pass the peverify output).
1356 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
1357 initializer for static and instance variables.
1358 (Constructor::Emit): Allow initializer to be null in the case of
1359 static constructors. Only emit initializer for instance
1362 (TypeContainer::FindMembers): Return a null array if there are no

1372 * driver.cs: Stop compilation if there are parse errors.
1374 * cs-parser.jay (constructor_declaration): Provide default base

1380 * class.cs: Do not emit parent class initializers for static
1381 constructors, that should be flagged as an error.
1383 2001-09-18 Ravi Pratap <ravi@ximian.com>
1385 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
1386 Move back code into TypeContainer::Populate.
1388 2001-09-18 Ravi Pratap <ravi@ximian.com>
1390 * class.cs (TypeContainer::AddConstructor): Fix the check to

1392 (Operator::OpType): Change Plus and Minus to Add and Subtract.
1394 * cs-parser.jay : Update accordingly.
1396 * class.cs (TypeContainer::FindMembers): For the case where we are searching
1397 for methods, don't forget to look into the operators too.

1399 methods, constructors and operators.
1400 (Operator::Define): Completely revamp.

1412 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
1415 (Expression::MemberLookup): Provide a version that allows to
1416 specify the MemberTypes and BindingFlags.
1418 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
1419 so it was not fetching variable information from outer blocks.
1421 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
1422 Beforefieldinit as it was buggy.

1460 and Unary::Operator.
1462 * cs-parser.jay (operator_declaration, CheckBinaryOperator, CheckUnaryOperator): Update
1465 * expression.cs (Binary::method): New member to hold the MethodBase for the case when
1466 we have overloaded operators.
1467 (Binary::ResolveOperator): Implement the part which does the operator overload

1471 (TypeContainer::Emit): Emit the operators we have too.

1478 * rootcontext.cs: Fix bug: tree.Namespaces might be null.
1480 2001-09-16 Ravi Pratap <ravi@ximian.com>
1482 * class.cs (EmitStaticFieldInitializers, EmitFieldInitializers): Make public.
1483 (TypeContainer::EmitConstructor): Remove and move code into Contructor::Emit.

1525 have to cope with the
1527 2001-09-14 Ravi Pratap <ravi@ximian.com>
1529 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

1534 * driver.cs: Added --parse option that only parses its input files
1537 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
1538 incorrect. IsTopLevel is not used to tell whether an object is
1539 root_types or not (that can be achieved by testing this ==
1540 root_types). But to see if this is a top-level *class* (not
1541 necessarly our "toplevel" container).
1543 2001-09-14 Ravi Pratap <ravi@ximian.com>
1545 * enum.cs (Enum::Define): Modify to call the Lookup method on the

1550 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
1551 Modifiers.TypeAttr. This should just be a call to that method.
1553 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
1554 object so that we can determine if we are top-level or not.
1556 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the

1567 * modifiers.cs (MethodAttr): Re-write.
1568 (EventAttr): Remove altogether as there seems to be no ostensible use for it.

1571 of top-level types as claimed.
1573 2001-09-13 Miguel de Icaza <miguel@ximian.com>
1575 * expression.cs (MemberLookup): Fruitless attempt to lookup
1576 constructors. Maybe I need to emit default constructors? That
1577 might be it (currently .NET emits this for me automatically).

1579 (Invocation::EmitArguments): new function, shared by the new

1601 objects that we might have around.
1603 (Populate): Only initialize method_builders_to_methods once.
1605 * expression.cs (PropertyExpr): Initialize type from the
1608 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

1613 (Binary::ResolveOperator): Set the return type to boolean for
1614 comparission operators
1616 * typemanager.cs: Remove debugging print code.
1618 (Invocation::Resolve): resolve type.
1620 * class.cs: Allocate a MemberInfo of the correct size, as the code
1621 elsewhere depends on the test to reflect the correct contents.
1623 (Method::) Keep track of parameters, due to System.Reflection holes
1625 (TypeContainer::Populate): Keep track of MethodBuilders to Method
1628 (TypeContainer::FindMembers): Use ArrayList and then copy an array
1629 of the exact size and return that.
1631 (Class::LookupMethodByBuilder): New function that maps
1632 MethodBuilders to its methods. Required to locate the information
1633 on methods because System.Reflection bit us again.
1635 * support.cs: New file, contains an interface ParameterData and
1636 two implementations: ReflectionParameters and InternalParameters
1637 used to access Parameter information. We will need to grow this
1640 * expression.cs (Invocation::GetParameterData): implement a cache
1641 and a wrapper around the ParameterData creation for methods.
1642 (Invocation::OverloadResolve): Use new code.
1644 2001-09-13 Ravi Pratap <ravi@ximian.com>

2068 2001-09-01 Ravi Pratap <ravi@che.iitm.ac.in>
2070 * class.cs (Event::Define): Implement.
2071 (Event.EventBuilder): New member.
2073 * class.cs (TypeContainer::Populate): Update to define all enums and events
2075 (Events): New property for the events arraylist we hold. Shouldn't we move to using
2076 readonly fields for all these cases ?
2078 2001-08-31 Ravi Pratap <ravi@che.iitm.ac.in>
2080 * class.cs (Property): Revamp to use the convention of making fields readonly.
2081 Accordingly modify code elsewhere.
2083 * class.cs : Apply patch from Mr. Mandar <go_mono@hotmail.com> for implementing
2084 the Define method of the Property class.
2086 * class.cs : Clean up applied patch and update references to variables etc. Fix
2088 (TypeContainer::Populate): Update to define all the properties we have. Also
2089 define all enumerations.
2091 * enum.cs (Define): Implement.
2093 2001-08-31 Ravi Pratap <ravi@che.iitm.ac.in>
2095 * cs-parser.jay (overloadable_operator): The semantic value is an
2096 enum of the Operator class.
2097 (operator_declarator): Implement actions.
2098 (operator_declaration): Implement.
2100 * class.cs (Operator::CheckUnaryOperator): New static method to help in checking
2101 validity of definitions.
2102 (Operator::CheckBinaryOperator): Static method to check for binary operators
2103 (TypeContainer::AddOperator): New method to add an operator to a type.
2105 * cs-parser.jay (indexer_declaration): Added line to actually call the
2106 AddIndexer method so it gets added ;-)
2108 * ../errors/errors.txt : Update to include new error numbers. Are these numbers
2109 already taken care of by the MS compiler ?
2111 2001-08-29 Ravi Pratap <ravi@che.iitm.ac.in>
2113 * class.cs (Operator): New class for operator declarations.
2114 (Operator::OpType): Enum for the various operators.
2116 2001-08-29 Ravi Pratap <ravi@che.iitm.ac.in>
2118 * class.cs (TypeContainer::AddIndexer): Remove FIXME comment. We

2121 * cs-parser.jay (general_catch_clause): Comment out
2122 (specific_catch_clauses, specific_catch_clause): Ditto.
2123 (opt_general_catch_clause, opt_specific_catch_clauses): Ditto

2125 (catch_clause): Rewrite to use the new productions above
2126 (catch_clauses): Modify accordingly.
2127 (opt_catch_clauses): New production to use in try_statement
2128 (try_statement): Revamp. Basically, we get rid of one unnecessary rule
2129 and re-write the code in the actions to extract the specific and
2130 general catch clauses by being a little smart ;-)
2132 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
2133 Hooray, try and catch statements parse fine !
2135 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2137 * statement.cs (Block::GetVariableType): Fix logic to extract the type
2138 string from the hashtable of variables.
2140 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did
2141 I end up making that mistake ;-)
2142 (catch_clauses): Fixed gross error which made Key and Value of the
2143 DictionaryEntry the same : $1 !!
2145 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2147 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
2149 * cs-parser.jay (event_declaration): Correct to remove the semicolon
2150 when the add and remove accessors are specified.
2152 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2154 * cs-parser.jay (IndexerDeclaration): New helper class to hold
2155 information about indexer_declarator.
2156 (indexer_declarator): Implement actions.
2157 (parsing_indexer): New local boolean used to keep track of whether
2158 we are parsing indexers or properties. This is necessary because
2159 implicit_parameters come into picture even for the get accessor in the
2161 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
2163 * class.cs (Indexer): New class for indexer declarations.
2164 (TypeContainer::AddIndexer): New method to add an indexer to a type.
2165 (TypeContainer::indexers): New member to hold list of indexers for the
2168 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
2170 * cs-parser.jay (add_accessor_declaration): Implement action.
2171 (remove_accessor_declaration): Implement action.
2172 (event_accessors_declaration): Implement

2177 (TypeContainer::AddEvent): New method to add an event to a type
2178 (TypeContainer::events): New member to hold list of events.

2182 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
2184 * cs-parser.jay (dim_separators): Implement. Make it a string
2185 concatenating all the commas together, just as they appear.
2186 (opt_dim_separators): Modify accordingly
2187 (rank_specifiers): Update accordingly. Basically do the same
2188 thing - instead, collect the brackets here.
2189 (opt_rank_sepcifiers): Modify accordingly.
2190 (array_type): Modify to actually return the complete type string
2191 instead of ignoring the rank_specifiers.
2192 (expression_list): Implement to collect the expressions
2193 (variable_initializer): Implement. We make it a list of expressions
2194 essentially so that we can handle the array_initializer case neatly too.
2195 (variable_initializer_list): Implement.
2196 (array_initializer): Make it a list of variable_initializers
2197 (opt_array_initializer): Modify accordingly.
2199 * expression.cs (New::NType): Add enumeration to help us
2200 keep track of whether we have an object/delegate creation
2201 or an array creation.
2202 (New:NewType, New::Rank, New::Indices, New::Initializers): New
2203 members to hold data about array creation.
2204 (New:New): Modify to update NewType
2205 (New:New): New Overloaded contructor for the array creation
2208 * cs-parser.jay (array_creation_expression): Implement to call
2209 the overloaded New constructor.
2211 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
2213 * class.cs (TypeContainer::Constructors): Return member
2214 constructors instead of returning null.
2216 2001-08-26 Miguel de Icaza <miguel@ximian.com>
2218 * typemanager.cs (InitCoreTypes): Initialize the various core
2219 types after we have populated the type manager with the user
2220 defined types (this distinction will be important later while
2221 compiling corlib.dll)
2223 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
2224 on Expression Classification. Now all expressions have a method
2225 `Resolve' and a method `Emit'.
2227 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
2228 generation from working. Also add some temporary debugging
2231 2001-08-24 Miguel de Icaza <miguel@ximian.com>
2233 * codegen.cs: Lots of code generation pieces. This is only the
2234 beginning, will continue tomorrow with more touches of polish. We
2235 handle the fundamentals of if, while, do, for, return. Others are
2236 trickier and I need to start working on invocations soon.
2238 * gen-treedump.cs: Bug fix, use s.Increment here instead of
2241 * codegen.cs (EmitContext): New struct, used during code
2242 emission to keep a context. Most of the code generation will be
2245 * cs-parser.jay: Add embedded blocks to the list of statements of
2246 this block. So code generation proceeds in a top down fashion.
2248 2001-08-23 Miguel de Icaza <miguel@ximian.com>
2250 * statement.cs: Add support for multiple child blocks.
2252 2001-08-22 Miguel de Icaza <miguel@ximian.com>
2254 * codegen.cs (EmitCode): New function, will emit the code for a
2255 Block of code given a TypeContainer and its ILGenerator.
2257 * statement.cs (Block): Standard public readonly optimization.
2258 (Block::Block constructors): Link children.
2259 (Block::Child): Child Linker.
2260 (Block::EmitVariables): Emits IL variable declarations.
2262 * class.cs: Drop support for MethodGroups here, delay until
2264 (Method::): Applied the same simplification that I did before, and
2265 move from Properties to public readonly fields.
2266 (Method::ParameterTypes): Returns the parameter types for the
2267 function, and implements a cache that will be useful later when I
2268 do error checking and the semantic analysis on the methods is
2270 (Constructor::GetCallingConvention): Renamed from CallingConvetion
2271 and made a method, optional argument tells whether this is a class
2272 or a structure to apply the `has-this' bit.
2273 (Method::GetCallingConvention): Implement, returns the calling
2275 (Method::Define): Defines the type, a second pass is performed
2276 later to populate the methods.
2278 (Constructor::ParameterTypes): implement a cache similar to the
2279 one on Method::ParameterTypes, useful later when we do semantic
2282 (TypeContainer::EmitMethod): New method. Emits methods.
2284 * expression.cs: Removed MethodGroup class from here.
2286 * parameter.cs (Parameters::GetCallingConvention): new method.

2293 (Constructor::CallingConvention): Returns the calling convention.
2294 (Constructor::ParameterTypes): Returns the constructor parameter
2297 (TypeContainer::AddConstructor): Keep track of default constructor
2298 and the default static constructor.
2300 (Constructor::) Another class that starts using `public readonly'
2301 instead of properties.
2303 (Constructor::IsDefault): Whether this is a default constructor.
2305 (Field::) use readonly public fields instead of properties also.
2307 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
2308 track of static constructors; If none is used, turn on
2309 BeforeFieldInit in the TypeAttributes.
2311 * cs-parser.jay (opt_argument_list): now the return can be null
2312 for the cases where there are no arguments.
2314 (constructor_declarator): If there is no implicit `base' or
2315 `this', then invoke the default parent constructor.
2317 * modifiers.cs (MethodAttr): New static function maps a set of
2318 modifiers flags into a MethodAttributes enum
2319 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
2320 MethodAttr, TypeAttr to represent the various mappings where the
2322 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
2324 2001-08-19 Miguel de Icaza <miguel@ximian.com>
2326 * parameter.cs (GetParameterInfo): Fix bug where there would be no
2329 * interface.cs (PopulateIndexer): Implemented the code generator
2330 for interface indexers.
2332 2001-08-17 Miguel de Icaza <miguel@ximian.com>
2334 * interface.cs (InterfaceMemberBase): Now we track the new status
2337 (PopulateProperty): Implement property population. Woohoo! Got
2338 Methods and Properties going today.
2340 Removed all the properties for interfaces, and replaced them with
2341 `public readonly' fields.
2343 2001-08-16 Miguel de Icaza <miguel@ximian.com>
2345 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
2346 initialize their hashtables/arraylists only when they are needed
2347 instead of doing this always.
2349 * parameter.cs: Handle refs and out parameters.
2351 * cs-parser.jay: Use an ArrayList to construct the arguments
2352 instead of the ParameterCollection, and then cast that to a
2355 * parameter.cs: Drop the use of ParameterCollection and use
2356 instead arrays of Parameters.
2358 (GetParameterInfo): Use the Type, not the Name when resolving
2361 2001-08-13 Miguel de Icaza <miguel@ximian.com>
2363 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
2364 and instead use public readonly fields.
2366 * class.cs: Put back walking code for type containers.
2368 2001-08-11 Miguel de Icaza <miguel@ximian.com>
2370 * class.cs (MakeConstant): Code to define constants.
2372 * rootcontext.cs (LookupType): New function. Used to locate types
2375 2001-08-08 Miguel de Icaza <miguel@ximian.com>
2377 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
2378 this System.Reflection code is. Kudos to Microsoft
2380 * typemanager.cs: Implement a type cache and avoid loading all
2381 types at boot time. Wrap in LookupType the internals. This made
2382 the compiler so much faster. Wow. I rule!
2384 * driver.cs: Make sure we always load mscorlib first (for
2385 debugging purposes, nothing really important).
2387 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
2388 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
2390 * rootcontext.cs: Lookup types on their namespace; Lookup types
2391 on namespaces that have been imported using the `using' keyword.
2393 * class.cs (TypeContainer::TypeAttr): Virtualize.
2394 (Class::TypeAttr): Return attributes suitable for this bad boy.
2395 (Struct::TypeAttr): ditto.
2396 Handle nested classes.
2397 (TypeContainer::) Remove all the type visiting code, it is now
2398 replaced with the rootcontext.cs code
2400 * rootcontext.cs (GetClassBases): Added support for structs.
2402 2001-08-06 Miguel de Icaza <miguel@ximian.com>
2404 * interface.cs, statement.cs, class.cs, parameter.cs,
2405 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
2406 Drop use of TypeRefs, and use strings instead.
2408 2001-08-04 Miguel de Icaza <miguel@ximian.com>
2412 * class.cs (Struct::Struct): set the SEALED flags after
2413 checking the modifiers.
2414 (TypeContainer::TypeAttr): new property, returns the
2415 TypeAttributes for a class.
2417 * cs-parser.jay (type_list): Oops, list production was creating a
2418 new list of base types.
2420 * rootcontext.cs (StdLib): New property.
2421 (GetInterfaceTypeByName): returns an interface by type name, and
2422 encapsulates error handling here.
2423 (GetInterfaces): simplified.
2424 (ResolveTree): Encapsulated all the tree resolution here.
2425 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
2428 * driver.cs: Add support for --nostdlib, to avoid loading the
2430 (Main): Do not put tree resolution here.
2432 * rootcontext.cs: Beginning of the class resolution.
2434 2001-08-03 Miguel de Icaza <miguel@ximian.com>
2436 * rootcontext.cs: Provide better error reporting.
2438 * cs-parser.jay (interface_base): set our $$ to be interfaces.
2440 * rootcontext.cs (CreateInterface): Handle the case where there
2441 are no parent interfaces.
2443 (CloseTypes): Routine to flush types at the end.
2444 (CreateInterface): Track types.
2445 (GetInterfaces): Returns an array of Types from the list of
2448 * typemanager.c (AddUserType): Mechanism to track user types (puts
2449 the type on the global type hash, and allows us to close it at the
2452 2001-08-02 Miguel de Icaza <miguel@ximian.com>
2454 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
2455 RecordInterface instead.
2457 * cs-parser.jay: Updated to reflect changes above.
2459 * decl.cs (Definition): Keep track of the TypeBuilder type that
2460 represents this type here. Not sure we will use it in the long
2461 run, but wont hurt for now.
2463 * driver.cs: Smaller changes to accomodate the new code.
2465 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
2468 * rootcontext.cs (CreateInterface): New method, used to create
2469 the System.TypeBuilder type for interfaces.
2470 (ResolveInterfaces): new entry point to resolve the interface
2472 (CodeGen): Property, used to keep track of the code generator.
2474 2001-07-26 Miguel de Icaza <miguel@ximian.com>
2476 * cs-parser.jay: Add a second production for delegate_declaration
2479 (enum_body): Put an opt_comma here instead of putting it on
2480 enum_body or enum_member_declarations so we can handle trailing
2481 commas on enumeration members. Gets rid of a shift/reduce.
2483 (type_list): Need a COMMA in the middle.
2485 (indexer_declaration): Tell tokenizer to recognize get/set
2487 * Remove old targets.
2489 * Re-add the parser target.
2491 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2493 * cs-parser.jay: Add precendence rules for a number of operators
2494 ot reduce the number of shift/reduce conflicts in the grammar.
2496 2001-07-17 Miguel de Icaza <miguel@ximian.com>
2498 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
2501 Get rid of old crufty code.
2503 * rootcontext.cs: Use this to keep track of the parsed
2504 representation and the defined types available to the program.
2506 * gen-treedump.cs: adjust for new convention.
2508 * type.cs: Split out the type manager, and the assembly builder
2511 * typemanager.cs: the type manager will live here now.
2513 * cil-codegen.cs: And the code generator here.

2521 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
2524 (unary_expression): Expand pre_increment_expression and
2525 post_decrement_expression to reduce a shift/reduce.

2529 * cs-tokenizer.cs: Hex numbers should begin with a 0.
2531 Improve allow_keyword_as_indent name.
2533 2001-06-19 Miguel de Icaza <miguel@ximian.com>
2535 * Adjustments for Beta2.
2537 2001-06-13 Miguel de Icaza <miguel@ximian.com>
2539 * decl.cs: Added `Define' abstract method.
2540 (InTransit): new property, used to catch recursive definitions.
2542 * interface.cs: Implement `Define'.
2544 * modifiers.cs: Map Modifiers.constants to
2545 System.Reflection.TypeAttribute flags.
2547 * class.cs: Keep track of types and user-defined types.
2548 (BuilderInit): New method for creating an assembly
2549 (ResolveType): New function to launch the resolution process, only
2550 used by interfaces for now.
2552 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
2553 that are inserted into the name space.
2555 2001-06-08 Miguel de Icaza <miguel@ximian.com>
2557 * ARGH. I have screwed up my tree so many times due to the use of
2558 rsync rather than using CVS. Going to fix this at once.
2560 * driver.cs: Objetify driver. Load assemblies, use assemblies to
2563 2001-06-07 Miguel de Icaza <miguel@ximian.com>
2565 * Experiment successful: Use System.Type rather that our own
2568 2001-05-25 Miguel de Icaza <miguel@ximian.com>
2570 * cs-parser.jay: Removed nsAliases from here.
2572 Use new namespaces, handle `using XXX;'
2574 * namespace.cs: Reimplemented namespace handling, use a recursive
2575 definition of the class. Now we can keep track of using clauses
2576 and catch invalid using clauses.
2578 2001-05-24 Miguel de Icaza <miguel@ximian.com>
2580 * gen-treedump.cs: Adapted for all the renaming.
2582 * expression.cs (Expression): this class now has a Type property
2583 which returns an expression Type.
2585 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
2586 `Type', as this has a different meaning now in the base
2588 2001-05-22 Miguel de Icaza <miguel@ximian.com>
2590 * interface.cs, class.cs: Removed from all the sources the
2591 references to signature computation, as we can not do method
2592 signature computation during the parsing time, as we are not
2593 trying to solve at that point distinguishing:
2597 void a (NS.Blah x) {}
2600 Which depending on the context might be valid or not, as we do not
2601 know if Blah is the same thing as NS.Blah at that point.
2603 * Redid everything so the code uses TypeRefs now instead of
2604 Types. TypeRefs are just temporary type placeholders, that need
2605 to be resolved. They initially have a pointer to a string and the
2606 current scope in which they are used. This is used later by the
2607 compiler to resolve the reference to an actual Type.
2609 * DeclSpace is no longer a CIR.Type, and neither are
2610 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
2611 are all DeclSpaces, but no Types.
2613 * type.cs (TypeRefManager): This implements the TypeRef manager,
2614 which keeps track of all the types that need to be resolved after
2615 the parsing has finished.
2617 2001-05-13 Miguel de Icaza <miguel@ximian.com>
2619 * ARGH. We are going to have to store `foreach' as a class rather
2620 than resolving it, as we need to verify error 1579 after name
2621 resolution. *OR* we could keep a flag that says `This request to
2622 IEnumerator comes from a foreach statement' which we can then use
2623 to generate the error.
2625 2001-05-10 Miguel de Icaza <miguel@ximian.com>
2627 * class.cs (TypeContainer.AddMethod): we now add methods to the
2628 MethodGroup instead of the method hashtable.
2630 * expression.cs: Add MethodGroup abstraction, which gets us one
2631 step closer to the specification in the way we handle method
2634 * cs-parser.jay (primary_expression): qualified_identifier now
2635 tried to match up an identifier to a local variable reference or
2636 to a parameter reference.
2638 current_local_parameters is now a parser global variable that
2639 points to the current parameters for the block, used during name
2642 (property_declaration): Now creates an implicit `value' argument to
2645 2001-05-09 Miguel de Icaza <miguel@ximian.com>
2647 * parameter.cs: Do not use `param' arguments as part of the
2648 signature, per the spec.
2650 2001-05-08 Miguel de Icaza <miguel@ximian.com>
2652 * decl.cs: Base class for classes, structs and interfaces. This
2653 is the "Declaration Space"
2655 * cs-parser.jay: Use CheckDef for checking declaration errors
2656 instead of having one on each function.
2658 * class.cs: Factor out some code for handling error handling in
2659 accordance to the "Declarations" section in the "Basic Concepts"
2660 chapter in the ECMA C# spec.
2662 * interface.cs: Make all interface member classes derive from
2663 InterfaceMemberBase.
2665 2001-05-07 Miguel de Icaza <miguel@ximian.com>
2667 * Many things: all interfaces are parsed and generated in
2668 gen-treedump. Support for member variables, constructors,
2669 destructors, properties, constants is there.
2671 Beginning of the IL backend, but very little done, just there for
2674 2001-04-29 Miguel de Icaza <miguel@ximian.com>
2676 * cs-parser.jay: Fix labeled statement.
2678 * cs-tokenizer.cs (escape): Escape " and ' always.
2679 ref_line, ref_name: keep track of the line/filename as instructed
2680 by #line by the compiler.
2683 2001-04-27 Miguel de Icaza <miguel@ximian.com>
2685 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
2686 to match the values in System.CodeDOM.
2688 Divid renamed to Divide.
2690 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
2692 (Statements.set): remove.
2694 * System.CodeDOM/CodeCatchClause.cs: always have a valid
2697 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
2698 falseStatements always have valid values.
2700 * cs-parser.jay: Use System.CodeDOM now.
