766 name as it is a type declaration.
768 * delegate.cs (ReturnType, Name): Rename members to these. Make them
771 (DefineDelegate): Renamed from Define. Does the same thing essentially,
772 as TypeContainer::DefineType.
774 (Populate): Method in which all the definition of the various methods (Invoke)
777 (Emit): Emit any code, if necessary. I am not sure about this really, but let's
780 (CloseDelegate): Finally creates the delegate.
782 * class.cs (TypeContainer::DefineType): Update to define delegates.
783 (Populate, Emit and CloseType): Do the same thing here too.
785 * rootcontext.cs (ResolveTree, PopulateTypes, EmitCode, CloseTypes): Include
786 delegates in all these operations.
788 2001-10-14 Miguel de Icaza <miguel@ximian.com>
790 * expression.cs: LocalTemporary: a new expression used to
791 reference a temporary that has been created.
793 * assign.cs: Handle PropertyAccess back here, so that we can
794 provide the proper semantic access to properties.
796 * expression.cs (Expression::ConvertReferenceExplicit): Implement
797 a few more explicit conversions.
799 * modifiers.cs: `NEW' modifier maps to HideBySig.
801 * expression.cs (PropertyExpr): Make this into an
802 ExpressionStatement, and support the EmitStatement code path.
804 Perform get/set error checking, clean up the interface.
806 * assign.cs: recognize PropertyExprs as targets, and if so, turn
807 them into toplevel access objects.
809 2001-10-12 Miguel de Icaza <miguel@ximian.com>
811 * expression.cs: PropertyExpr::PropertyExpr: use work around the
814 * typemanager.cs: Keep track here of our PropertyBuilders again to
815 work around lameness in SRE.
817 2001-10-11 Miguel de Icaza <miguel@ximian.com>
819 * expression.cs (LValue::LValueResolve): New method in the
820 interface, used to perform a second resolution pass for LValues.
822 (This::DoResolve): Catch the use of this in static methods.
824 (This::LValueResolve): Implement.
826 (This::Store): Remove warning, assigning to `this' in structures
829 (Invocation::Emit): Deal with invocation of
830 methods on value types. We need to pass the address to structure
831 methods rather than the object itself. (The equivalent code to
832 emit "this" for structures leaves the entire structure on the
833 stack instead of a pointer to it).
835 (ParameterReference::DoResolve): Compute the real index for the
836 argument based on whether the method takes or not a `this' pointer
837 (ie, the method is static).
839 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store
840 value types returned from functions when we need to invoke a
841 method on the sturcture.
844 2001-10-11 Ravi Pratap <ravi@ximian.com>
846 * class.cs (TypeContainer::DefineType): Method to actually do the business of
847 defining the type in the Modulebuilder or Typebuilder. This is to take
848 care of nested types which need to be defined on the TypeBuilder using
851 (TypeContainer::GetClassBases): Implement. Essentially the code from the
852 methods in RootContext, only ported to be part of TypeContainer.
854 (TypeContainer::GetInterfaceOrClass): Ditto.
856 (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
858 * interface.cs (Interface::DefineInterface): New method. Does exactly
859 what RootContext.CreateInterface did earlier, only it takes care of nested types
862 (Interface::GetInterfaces): Move from RootContext here and port.
864 (Interface::GetInterfaceByName): Same here.
866 * rootcontext.cs (ResolveTree): Re-write.
868 (PopulateTypes): Re-write.
870 * class.cs (TypeContainer::Populate): Populate nested types too.
871 (TypeContainer::Emit): Emit nested members too.
873 * typemanager.cs (AddUserType): Do not make use of the FullName property,
874 instead just use the name argument passed in as it is already fully
877 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
878 to TypeContainer mapping to see if a type is user-defined.
880 * class.cs (TypeContainer::CloseType): Implement.
882 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
883 the default constructor.
885 (TypeContainer::Populate): Fix minor bug which led to creating default constructors
888 (Constructor::IsDefault): Fix up logic to determine if it is the default constructor
890 * interface.cs (CloseType): Create the type here.
892 * rootcontext.cs (CloseTypes): Re-write to recursively close types by running through
895 Remove all the methods which are now in TypeContainer.
897 2001-10-10 Ravi Pratap <ravi@ximian.com>
899 * delegate.cs (Define): Re-write bits to define the delegate
902 2001-10-10 Miguel de Icaza <miguel@ximian.com>
904 * makefile: Renamed the compiler to `mcs.exe' instead of compiler.exe

907 as a source to convert to any reference type.
909 * statement.cs (Return): Perform any implicit conversions to
910 expected return type.
912 Validate use of return statement.
914 * codegen.cs (EmitContext): Pass the expected return type here.
916 * class.cs (Method, Constructor, Property): Pass expected return
919 2001-10-09 Miguel de Icaza <miguel@ximian.com>
921 * expression.cs: Make DoResolve take an EmitContext instead of a
924 Replaced `l' and `location' for `loc', for consistency.
926 (Error, Warning): Remove unneeded Tc argument.
928 * assign.cs, literal.cs, constant.cs: Update to new calling
931 * codegen.cs: EmitContext now contains a flag indicating whether
932 code is being generated in a static method or not.
934 * cs-parser.jay: DecomposeQI, new function that replaces the old
935 QualifiedIdentifier. Now we always decompose the assembled
936 strings from qualified_identifier productions into a group of
939 2001-10-08 Miguel de Icaza <miguel@ximian.com>
941 * rootcontext.cs: Deal with field-less struct types correctly now
942 by passing the size option to Define Type.
944 * class.cs: Removed hack that created one static field.
946 2001-10-07 Miguel de Icaza <miguel@ximian.com>
948 * statement.cs: Moved most of the code generation here.
950 2001-10-09 Ravi Pratap <ravi@ximian.com>
952 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
955 (ElementAccess): Remove useless bits for now - keep checks as the spec
958 2001-10-08 Ravi Pratap <ravi@ximian.com>
960 * expression.cs (ElementAccess::DoResolve): Remove my crap code
961 and start performing checks according to the spec.
963 2001-10-07 Ravi Pratap <ravi@ximian.com>
965 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
966 rank_specifiers instead.
968 (rank_specifiers): Change the order in which the rank specifiers are stored
970 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
972 * expression.cs (ElementAccess): Implement the LValue interface too.
974 2001-10-06 Ravi Pratap <ravi@ximian.com>
976 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
977 except that user defined conversions are not included.
979 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
980 perform the conversion of the return type, if necessary.
982 (New::DoResolve): Check whether we are creating an array or an object
983 and accordingly do the needful.
985 (New::Emit): Same here.
987 (New::DoResolve): Implement guts of array creation.
989 (New::FormLookupType): Helper function.
991 2001-10-07 Miguel de Icaza <miguel@ximian.com>
993 * codegen.cs: Removed most of the code generation here, and move the
994 corresponding code generation bits to the statement classes.
996 Added support for try/catch/finalize and throw.
998 * cs-parser.jay: Added support for try/catch/finalize.
1000 * class.cs: Catch static methods having the flags override,
1001 virtual or abstract.
1003 * expression.cs (UserCast): This user cast was not really doing
1004 what it was supposed to do. Which is to be born in fully resolved
1005 state. Parts of the resolution were being performed at Emit time!
1009 2001-10-05 Miguel de Icaza <miguel@ximian.com>
1011 * expression.cs: Implicity convert the result from UserCast.
1013 2001-10-05 Ravi Pratap <ravi@ximian.com>
1015 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
1016 prevented it from working correctly.
1018 (ConvertExplicit): Make the first try, a call to ConvertImplicitStandard, not
1019 merely ConvertImplicit.
1021 2001-10-05 Miguel de Icaza <miguel@ximian.com>
1023 * typemanager.cs: Make the LookupTypeContainer function static,
1024 and not per-instance.
1026 * class.cs: Make static FindMembers (the one that takes a Type
1029 * codegen.cs: Add EmitForeach here.
1031 * cs-parser.jay: Make foreach a toplevel object instead of the
1032 inline expansion, as we need to perform semantic analysis on it.
1034 2001-10-05 Ravi Pratap <ravi@ximian.com>
1036 * expression.cs (Expression::ImplicitUserConversion): Rename to
1037 UserDefinedConversion.
1039 (Expression::UserDefinedConversion): Take an extra argument specifying
1040 whether we look for explicit user conversions too.

1051 * expression.cs (Cast): Record location info.
1053 (Expression::ConvertExplicit): Take location argument.
1055 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
1056 to determine if we are doing explicit conversions.
1058 (UserCast::Emit): Update accordingly.
1060 (Expression::ConvertExplicit): Report an error if everything fails.
1062 * ../errors/cs0030.cs : Add.
1064 2001-10-04 Miguel de Icaza <miguel@ximian.com>
1066 * modifiers.cs: If the ABSTRACT keyword is present, also set the
1067 virtual and newslot bits.
1069 * class.cs (TypeContainer::RegisterRequiredImplementations):
1070 Record methods we need.
1072 (TypeContainer::MakeKey): Helper function to make keys for
1073 MethodBases, since the Methodbase key is useless.
1075 (TypeContainer::Populate): Call RegisterRequiredImplementations
1076 before defining the methods.
1078 Create a mapping for method_builders_to_methods ahead of time
1079 instead of inside a tight loop.
1081 (::RequireMethods): Accept an object as the data to set into the
1082 hashtable so we can report interface vs abstract method mismatch.
1084 2001-10-03 Miguel de Icaza <miguel@ximian.com>
1086 * report.cs: Make all of it static.
1088 * rootcontext.cs: Drop object_type and value_type computations, as
1089 we have those in the TypeManager anyways.
1091 Drop report instance variable too, now it is a global.
1093 * driver.cs: Use try/catch on command line handling.
1095 Add --probe option to debug the error reporting system with a test
1098 * report.cs: Add support for exiting program when a probe
1099 condition is reached.
1101 2001-10-03 Ravi Pratap <ravi@ximian.com>
1103 * expression.cs (Binary::DoNumericPromotions): Fix the case when
1104 we do a forcible conversion regardless of type, to check if
1105 ForceConversion returns a null.
1107 (Binary::error19): Use location to report error.
1109 (Unary::error23): Use location here too.
1111 * ../errors/cs0019.cs : Check in.
1113 * ../errors/cs0023.cs : Check in.
1115 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
1116 case of a non-null MethodInfo object with a length of 0 !
1118 (Binary::ResolveOperator): Flag error if overload resolution fails to find
1119 an applicable member - according to the spec :-)
1120 Also fix logic to find members in base types.
1122 (Unary::ResolveOperator): Same here.
1124 (Unary::report23): Change name to error23 and make first argument a TypeContainer
1125 as I was getting thoroughly confused between this and error19 :-)
1127 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
1128 (::FindMostEncompassedType): Implement.
1129 (::FindMostEncompassingType): Implement.
1130 (::StandardConversionExists): Implement.
1132 (UserImplicitCast): Re-vamp. We now need info about most specific
1133 source and target types so that we can do the necessary conversions.
1135 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
1136 mathematical union with no duplicates.
1138 2001-10-03 Miguel de Icaza <miguel@ximian.com>
1140 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
1141 in order from base classes to child classes, so that we can in
1142 child classes look up in our parent for method names and
1143 attributes (required for handling abstract, virtual, new, override
1144 constructs: we need to instrospect our base class, and if we dont
1145 populate the classes in order, the introspection might be
1146 incorrect. For example, a method could query its parent before
1147 the parent has any methods and would determine that the parent has
1148 no abstract methods (while it could have had them)).
1150 (RootContext::CreateType): Record the order in which we define the
1153 2001-10-02 Miguel de Icaza <miguel@ximian.com>
1155 * class.cs (TypeContainer::Populate): Also method definitions can
1156 fail now, keep track of this.
1158 (TypeContainer::FindMembers): Implement support for
1159 DeclaredOnly/noDeclaredOnly flag.
1161 (Constructor::Emit) Return the ConstructorBuilder.
1163 (Method::Emit) Return the MethodBuilder.
1164 Check for abstract or virtual methods to be public.
1166 * rootcontext.cs (RootContext::CreateType): Register all the
1167 abstract methods required for the class to be complete and the
1168 interface methods that must be implemented.
1170 * cs-parser.jay: Report error 501 (method requires body if it is
1171 not marked abstract or extern).
1173 * expression.cs (TypeOf::Emit): Implement.
1175 * typemanager.cs: runtime_handle_type, new global type.
1177 * class.cs (Property::Emit): Generate code for properties.
1179 2001-10-02 Ravi Pratap <ravi@ximian.com>
1181 * expression.cs (Unary::ResolveOperator): Find operators on base type
1182 too - we now conform exactly to the spec.
1184 (Binary::ResolveOperator): Same here.
1186 * class.cs (Operator::Define): Fix minor quirk in the tests.
1188 * ../errors/cs0215.cs : Added.
1190 * ../errors/cs0556.cs : Added.
1192 * ../errors/cs0555.cs : Added.
1194 2001-10-01 Miguel de Icaza <miguel@ximian.com>
1196 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
1197 single integer which is really efficient
1199 2001-10-01 Ravi Pratap <ravi@ximian.com>
1201 * expression.cs (Expression::ImplicitUserConversion): Use location
1202 even in the case when we are examining True operators.
1204 * class.cs (Operator::Define): Perform extensive checks to conform
1205 with the rules for operator overloading in the spec.
1207 * expression.cs (Expression::ImplicitReferenceConversion): Implement
1208 some of the other conversions mentioned in the spec.
1210 * typemanager.cs (array_type): New static member for the System.Array built-in
1213 (cloneable_interface): For System.ICloneable interface.
1215 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
1216 we start resolving the tree and populating types.
1218 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
1220 2001-10-01 Miguel de Icaza <miguel@ximian.com>
1222 * expression.cs (Expression::ExprClassFromMemberInfo,
1223 Expression::Literalize): Create literal expressions from
1224 FieldInfos which are literals.
1226 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
1227 type casts, because they were wrong. The test suite in tests
1230 (ImplicitNumericConversion): ushort to ulong requires a widening
1233 Int32 constant to long requires widening cast as well.
1235 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
1236 for integers because the type on the stack is not i4.
1238 2001-09-30 Miguel de Icaza <miguel@ximian.com>
1240 * expression.cs (report118): require location argument.
1242 * parameter.cs: Do not dereference potential null value.
1244 * class.cs: Catch methods that lack the `new' keyword when
1245 overriding a name. Report warnings when `new' is used without
1246 anything being there to override.
1248 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
1250 * class.cs: Only add constructor to hashtable if it is non-null
1251 (as now constructors can fail on define).
1253 (TypeManager, Class, Struct): Take location arguments.
1255 Catch field instance initialization in structs as errors.
1257 accepting_filter: a new filter for FindMembers that is static so
1258 that we dont create an instance per invocation.
1260 (Constructor::Define): Catch errors where a struct constructor is
1263 * cs-parser.jay: Pass location information for various new
1266 * delegate.cs (Delegate): take a location argument.
1268 * driver.cs: Do not call EmitCode if there were problesm in the
1269 Definition of the types, as many Builders wont be there.
1271 * decl.cs (Decl::Decl): Require a location argument.
1273 * cs-tokenizer.cs: Handle properly hex constants that can not fit
1274 into integers, and find the most appropiate integer for it.
1276 * literal.cs: Implement ULongLiteral.
1278 * rootcontext.cs: Provide better information about the location of
1279 failure when CreateType fails.
1281 2001-09-29 Miguel de Icaza <miguel@ximian.com>
1283 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
1286 * expression.cs (Binary::CheckShiftArguments): Add missing type
1288 (Binary::ResolveOperator): Add type to the logical and and logical
1289 or, Bitwise And/Or and Exclusive Or code paths, it was missing
1292 (Binary::DoNumericPromotions): In the case where either argument
1293 is ulong (and most signed types combined with ulong cause an
1294 error) perform implicit integer constant conversions as well.
1296 2001-09-28 Miguel de Icaza <miguel@ximian.com>
1298 * expression.cs (UserImplicitCast): Method should always be
1300 (Invocation::BetterConversion): Simplified test for IntLiteral.
1302 (Expression::ImplicitNumericConversion): Split this routine out.
1303 Put the code that performs implicit constant integer conversions
1306 (Expression::Resolve): Become a wrapper around DoResolve so we can
1307 check eclass and type being set after resolve.
1309 (Invocation::Badness): Remove this dead function
1311 (Binary::ResolveOperator): Do not compute the expensive argumnets
1312 unless we have a union for it.
1314 (Probe::Emit): Is needs to do an isinst and then
1315 compare against null.
1317 (::CanConvert): Added Location argument. If the Location argument
1318 is null (Location.Null), then we do not report errors. This is
1319 used by the `probe' mechanism of the Explicit conversion. We do
1320 not want to generate an error for something that the user
1321 explicitly requested to be casted. But the pipeline for an
1322 explicit cast first tests for potential implicit casts.
1324 So for now, if the Location is null, it means `Probe only' to
1325 avoid adding another argument. Might have to revise this
1328 (ClassCast): New class used to type cast objects into arbitrary
1329 classes (used in Explicit Reference Conversions).
1331 Implement `as' as well.
1333 Reverted all the patches from Ravi below: they were broken:
1335 * The use of `level' as a mechanism to stop recursive
1336 invocations is wrong. That was there just to catch the
1337 bug with a strack trace but not as a way of addressing
1340 To fix the problem we have to *understand* what is going
1341 on and the interactions and come up with a plan, not
1342 just get things going.
1344 * The use of the type conversion cache that I proposed
1345 last night had an open topic: How does this work across
1346 protection domains. A user defined conversion might not
1347 be public in the location where we are applying the
1348 conversion, a different conversion might be selected
1349 (ie, private A->B (better) but public B->A (worse),
1350 inside A, A->B applies, but outside it, B->A will
1353 * On top of that (ie, even if the above is solved),
1354 conversions in a cache need to be abstract. Ie, `To
1355 convert from an Int to a Short use an OpcodeCast', not
1356 `To convert from an Int to a Short use the OpcodeCast on
1357 the variable 5' (which is what this patch was doing).
1359 2001-09-28 Ravi Pratap <ravi@ximian.com>
1361 * expression.cs (Invocation::ConversionExists): Re-write to use
1362 the conversion cache
1364 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
1365 cache all conversions done, not just user-defined ones.
1367 (Invocation::BetterConversion): The real culprit. Use ConversionExists
1368 to determine if a conversion exists instead of acutually trying to
1369 perform the conversion. It's faster too.
1371 (Expression::ConvertExplicit): Modify to use ConversionExists to check
1372 and only then attempt the implicit conversion.
1374 2001-09-28 Ravi Pratap <ravi@ximian.com>
1376 * expression.cs (ConvertImplicit): Use a cache for conversions
1377 already found. Check level of recursion and bail out if necessary.
1379 2001-09-28 Miguel de Icaza <miguel@ximian.com>
1381 * typemanager.cs (string_concat_string_string, string_concat_object_object):
1382 Export standard methods that we expect for string operations.
1384 * statement.cs (Block::UsageWarning): Track usage of variables and
1385 report the errors for not used variables.
1387 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
1390 2001-09-27 Miguel de Icaza <miguel@ximian.com>
1392 * codegen.cs: remove unnneded code
1394 * expression.cs: Removed BuiltinTypeAccess class
1396 Fix the order in which implicit conversions are
1399 The previous fixed dropped support for boxed conversions (adding a
1400 test to the test suite now)
1402 (UserImplicitCast::CanConvert): Remove test for source being null,
1403 that code is broken. We should not feed a null to begin with, if
1404 we do, then we should track the bug where the problem originates
1405 and not try to cover it up here.
1407 Return a resolved expression of type UserImplicitCast on success
1408 rather than true/false. Ravi: this is what I was talking about,
1409 the pattern is to use a static method as a "constructor" for
1412 Also, do not create arguments until the very last minute,
1413 otherwise we always create the arguments even for lookups that
1414 will never be performed.
1416 (UserImplicitCast::Resolve): Eliminate, objects of type
1417 UserImplicitCast are born in a fully resolved state.
1419 * typemanager.cs (InitCoreTypes): Init also value_type
1422 * expression.cs (Cast::Resolve): First resolve the child expression.
1424 (LValue): Add new method AddressOf to be used by
1427 Change the argument of Store to take an EmitContext instead of an
1428 ILGenerator, because things like FieldExpr need to be able to call
1429 their children expression to generate the instance code.
1431 (Expression::Error, Expression::Warning): Sugar functions for
1434 (Expression::MemberLookup): Accept a TypeContainer instead of a
1435 Report as the first argument.
1437 (Expression::ResolvePrimary): Killed. I still want to improve
1438 this as currently the code is just not right.
1440 (Expression::ResolveMemberAccess): Simplify, but it is still
1443 (Unary::Resolve): Catch errors in AddressOf operators.
1445 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
1446 index to a byte for the short-version, or the compiler will choose
1447 the wrong Emit call, which generates the wrong data.
1449 (ParameterReference::Emit, ::Store): same.
1451 (FieldExpr::AddressOf): Implement.
1453 * typemanager.cs: TypeManager: made public variable instead of
1456 * driver.cs: document --fatal.
1458 * report.cs (ErrorMessage, WarningMessage): new names for the old
1459 Error and Warning classes.
1461 * cs-parser.jay (member_access): Turn built-in access to types
1462 into a normal simplename
1464 2001-09-27 Ravi Pratap <ravi@ximian.com>

1471 2001-09-27 Ravi Pratap <ravi@ximian.com>
1473 * expression.cs (UserImplicitCast::Resolve): Fix bug.
1475 2001-09-27 Ravi Pratap <ravi@ximian.com>
1477 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug

1480 * expression.cs (UserImplicitCast::CanConvert): Static method to do
1481 the work of all the checking.
1482 (ConvertImplicit): Call CanConvert and only then create object if necessary.
1483 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
1485 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
1486 that is the right way.
1488 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
1489 overloading resolution. Use everywhere instead of cutting and pasting code.
1491 (Binary::ResolveOperator): Use MakeUnionSet.
1493 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
1494 we have to convert to bool types. Not complete yet.
1496 2001-09-27 Miguel de Icaza <miguel@ximian.com>
1498 * typemanager.cs (TypeManager::CSharpName): support ushort.
1500 * expression.cs (Expression::TryImplicitIntConversion): Attempts
1501 to provide an expression that performsn an implicit constant int
1502 conversion (section 6.1.6).
1503 (Expression::ConvertImplicitRequired): Reworked to include
1504 implicit constant expression conversions.
1506 (Expression::ConvertNumericExplicit): Finished.
1508 (Invocation::Emit): If InstanceExpression is null, then it means
1509 that we perform a call on this.
1511 2001-09-26 Miguel de Icaza <miguel@ximian.com>
1513 * expression.cs (Unary::Emit): Remove some dead code.
1514 (Probe): Implement Resolve and Emit for `is'.
1515 (Expression::ConvertImplicitRequired): Attempt to do constant
1516 expression conversions here. Maybe should be moved to
1517 ConvertImplicit, but I am not sure.
1518 (Expression::ImplicitLongConstantConversionPossible,
1519 Expression::ImplicitIntConstantConversionPossible): New functions
1520 that tell whether is it possible to apply an implicit constant
1521 expression conversion.

1534 ones that the spec expects (as we are just stringizing the
1537 * expression.cs (Unary::ResolveOperator): Fix bug: Use
1538 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
1539 previous usage did only work for our methods.
1540 (Expression::ConvertImplicit): Handle decimal implicit numeric
1541 conversions as well.
1542 (Expression::InternalTypeConstructor): Used to invoke constructors
1543 on internal types for default promotions.
1545 (Unary::Emit): Implement special handling for the pre/post
1546 increment/decrement for overloaded operators, as they need to have
1547 the same semantics as the other operators.
1549 (Binary::ResolveOperator): ditto.
1550 (Invocation::ConversionExists): ditto.
1551 (UserImplicitCast::Resolve): ditto.
1553 2001-09-26 Ravi Pratap <ravi@ximian.com>
1555 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded

1570 expressions that can appear in statements, so that we can provide
1571 an alternate path to generate expression that do not leave a value
1574 (Expression::Emit, and all the derivatives): We no longer return
1575 whether a value is left on the stack or not. Every expression
1576 after being emitted leaves a single value on the stack.
1578 * codegen.cs (EmitContext::EmitStatementExpression): Use the
1579 facilties of ExpressionStatement if possible.
1581 * cs-parser.jay: Update statement_expression.

1602 (ConvertImplicit): Do user-defined conversion if it exists.
1604 2001-09-24 Miguel de Icaza <miguel@ximian.com>
1606 * assign.cs: track location.
1607 (Resolve): Use implicit conversions on assignment.
1609 * literal.cs: Oops. Not good, Emit of short access values should

1650 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
1651 Also take an additional TypeContainer argument.

1672 * typemanager.cs: declare and load enum_type, delegate_type and
1675 * expression.cs (Expression::Emit): Now emit returns a value that
1676 tells whether a value is left on the stack or not. This strategy
1677 might be reveted tomorrow with a mechanism that would address
1678 multiple assignments.
1679 (Expression::report118): Utility routine to report mismatches on
1682 (Unary::Report23): Report impossible type/operator combination
1685 (Unary::IsIncrementableNumber): Whether the type can be

1731 functions, throw exceptions so it is obvious that we are facing a
1734 * cs-parser.jay (invocation_expression): Pass Location information.
1736 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
1737 Use a basename for those routines because .NET does not like paths

1749 * expression.cs (Unary::ResolveOperator): return the child
1750 expression for expressions which are just +expr.
1751 (Unary::ResolveOperator): Return negative literals for -LITERAL
1752 expressions (otherwise they are Unary {Literal}).
1753 (Invocation::Badness): Take into account `Implicit constant
1754 expression conversions'.
1756 * literal.cs (LongLiteral): Implement long literal class.
1757 (IntLiteral): export the `Value' of the intliteral.
1759 2001-09-19 Ravi Pratap <ravi@ximian.com>

1774 * expression.cs (Unary::Resolve): Implement.
1775 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
1776 operators are found instead of making noise ;-)
1777 (Unary::ResolveOperator): New method to do precisely the same thing which
1778 Binary::ResolveOperator does for Binary expressions.
1779 (Unary.method, .Arguments): Add.
1780 (Unary::OperName): Implement.
1781 (Unary::ForceConversion): Copy and Paste !
1783 * class.cs (Operator::Define): Fix a small bug for the case when we have
1786 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
1787 for the inbuilt operators. Only overloading works for now ;-)
1789 2001-09-18 Miguel de Icaza <miguel@ximian.com>
1791 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
1792 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

1805 (FieldExpr::Emit): Implement.
1807 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
1808 the last instruction contains a return opcode to avoid generating
1809 the last `ret' instruction (this generates correct code, and it is
1810 nice to pass the peverify output).
1812 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
1813 initializer for static and instance variables.
1814 (Constructor::Emit): Allow initializer to be null in the case of
1815 static constructors. Only emit initializer for instance
1818 (TypeContainer::FindMembers): Return a null array if there are no

1828 * driver.cs: Stop compilation if there are parse errors.
1830 * cs-parser.jay (constructor_declaration): Provide default base

1833 initializers if none was specified.
1834 Catch the fact that constructors should not have parameters.
1836 * class.cs: Do not emit parent class initializers for static
1837 constructors, that should be flagged as an error.
1839 2001-09-18 Ravi Pratap <ravi@ximian.com>
1841 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
1842 Move back code into TypeContainer::Populate.

1871 (Expression::MemberLookup): Provide a version that allows to
1872 specify the MemberTypes and BindingFlags.
1874 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
1875 so it was not fetching variable information from outer blocks.
1877 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
1878 Beforefieldinit as it was buggy.
1880 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
1883 * class.cs (Constructor::Emit): Only emit if block is not null.
1884 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
1885 deal with this by semantically definining it as if the user had
1888 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
1889 constructors as we now "emit" them at a higher level.

1892 default constructors if none was provided.
1894 (ConstructorInitializer): Add methods Resolve and Emit.
1896 * expression.cs: Cast to ConstructorInfo instead of MethodInfo

1916 and Unary::Operator.
1918 * cs-parser.jay (operator_declaration, CheckBinaryOperator, CheckUnaryOperator): Update

1922 we have overloaded operators.
1923 (Binary::ResolveOperator): Implement the part which does the operator overload
1926 * class.cs (Operator::Emit): Implement.
1927 (TypeContainer::Emit): Emit the operators we have too.
1929 * expression.cs (Binary::Emit): Update to emit the appropriate code for
1930 the case when we have a user-defined operator.

1936 2001-09-16 Ravi Pratap <ravi@ximian.com>

1973 Load System assembly as well as part of the standard library.
1975 * report.cs: Allow throwing exceptions on errors for debugging.
1977 * modifiers.cs: Do not use `parent', instead use the real type
1978 container to evaluate permission settings.
1980 * class.cs: Put Ravi's patch back in. He is right, and we will
1981 have to cope with the
1983 2001-09-14 Ravi Pratap <ravi@ximian.com>
1985 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

1990 * driver.cs: Added --parse option that only parses its input files
1993 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
1994 incorrect. IsTopLevel is not used to tell whether an object is
1995 root_types or not (that can be achieved by testing this ==
1996 root_types). But to see if this is a top-level *class* (not
1997 necessarly our "toplevel" container).
1999 2001-09-14 Ravi Pratap <ravi@ximian.com>
2001 * enum.cs (Enum::Define): Modify to call the Lookup method on the
2002 parent instead of a direct call to GetType.
2004 2001-09-14 Ravi Pratap <ravi@ximian.com>
2006 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
2007 Modifiers.TypeAttr. This should just be a call to that method.
2009 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
2010 object so that we can determine if we are top-level or not.
2012 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
2015 * enum.cs (Enum::Define): Ditto.
2017 * modifiers.cs (FieldAttr): Re-write.
2019 * class.cs (TypeContainer::IsTopLevel): Change accessibility to public.
2020 (TypeContainer::HaveStaticConstructor): New property to provide access
2021 to precisely that info.
2023 * modifiers.cs (MethodAttr): Re-write.
2024 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
2026 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
2027 of top-level types as claimed.
2029 2001-09-13 Miguel de Icaza <miguel@ximian.com>
2031 * expression.cs (MemberLookup): Fruitless attempt to lookup
2032 constructors. Maybe I need to emit default constructors? That
2033 might be it (currently .NET emits this for me automatically).
2034 (Invocation::OverloadResolve): Cope with Arguments == null.
2035 (Invocation::EmitArguments): new function, shared by the new
2037 (Invocation::Emit): Handle static and instance methods. Emit
2038 proper call instruction for virtual or non-virtual invocations.
2039 (New::Emit): Implement.
2040 (New::Resolve): Implement.
2041 (MemberAccess:Resolve): Implement.

2049 SimpleLookup): Auxiliary routines to help parse a qualifier
2052 Update qualifier_identifier rule.
2054 * codegen.cs: Removed debugging messages.
2056 * class.cs: Make this a global thing, this acts just as a "key" to
2057 objects that we might have around.
2059 (Populate): Only initialize method_builders_to_methods once.
2061 * expression.cs (PropertyExpr): Initialize type from the
2064 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
2065 Resolve pattern. Attempt to implicitly convert value to boolean.
2068 * expression.cs: Set the type for the int32/int32 argument case.
2069 (Binary::ResolveOperator): Set the return type to boolean for
2070 comparission operators
2072 * typemanager.cs: Remove debugging print code.
2074 (Invocation::Resolve): resolve type.
2076 * class.cs: Allocate a MemberInfo of the correct size, as the code
2077 elsewhere depends on the test to reflect the correct contents.
2079 (Method::) Keep track of parameters, due to System.Reflection holes
2081 (TypeContainer::Populate): Keep track of MethodBuilders to Method
2084 (TypeContainer::FindMembers): Use ArrayList and then copy an array
2085 of the exact size and return that.
2087 (Class::LookupMethodByBuilder): New function that maps
2088 MethodBuilders to its methods. Required to locate the information
2089 on methods because System.Reflection bit us again.
2091 * support.cs: New file, contains an interface ParameterData and
2092 two implementations: ReflectionParameters and InternalParameters
2093 used to access Parameter information. We will need to grow this
2096 * expression.cs (Invocation::GetParameterData): implement a cache
2097 and a wrapper around the ParameterData creation for methods.
2098 (Invocation::OverloadResolve): Use new code.
2100 2001-09-13 Ravi Pratap <ravi@ximian.com>
2102 * class.cs (TypeContainer::EmitField): Remove and move into
2103 (Field::Define): here and modify accordingly.
2104 (Field.FieldBuilder): New member.
2105 (TypeContainer::Populate): Update accordingly.
2106 (TypeContainer::FindMembers): Implement.
2108 2001-09-13 Miguel de Icaza <miguel@ximian.com>
2110 * statement.cs: (VariableInfo::VariableType): New field to be
2111 initialized with the full type once it is resolved.

2409 will is used during the tree rewriting as we resolve them during

2585 and re-write the code in the actions to extract the specific and
2586 general catch clauses by being a little smart ;-)
2588 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
2589 Hooray, try and catch statements parse fine !

2647 instead of ignoring the rank_specifiers.
2648 (expression_list): Implement to collect the expressions

2653 (opt_array_initializer): Modify accordingly.

2684 generation from working. Also add some temporary debugging
2687 2001-08-24 Miguel de Icaza <miguel@ximian.com>
2689 * codegen.cs: Lots of code generation pieces. This is only the
2690 beginning, will continue tomorrow with more touches of polish. We

2698 emission to keep a context. Most of the code generation will be

2721 move from Properties to public readonly fields.
2722 (Method::ParameterTypes): Returns the parameter types for the
2723 function, and implements a cache that will be useful later when I
2724 do error checking and the semantic analysis on the methods is
2726 (Constructor::GetCallingConvention): Renamed from CallingConvetion
2727 and made a method, optional argument tells whether this is a class
2728 or a structure to apply the `has-this' bit.
2729 (Method::GetCallingConvention): Implement, returns the calling
2731 (Method::Define): Defines the type, a second pass is performed
2732 later to populate the methods.
2734 (Constructor::ParameterTypes): implement a cache similar to the
2735 one on Method::ParameterTypes, useful later when we do semantic
2738 (TypeContainer::EmitMethod): New method. Emits methods.
2740 * expression.cs: Removed MethodGroup class from here.
2742 * parameter.cs (Parameters::GetCallingConvention): new method.

2749 (Constructor::CallingConvention): Returns the calling convention.
2750 (Constructor::ParameterTypes): Returns the constructor parameter
2753 (TypeContainer::AddConstructor): Keep track of default constructor
2754 and the default static constructor.
2756 (Constructor::) Another class that starts using `public readonly'
2757 instead of properties.
2759 (Constructor::IsDefault): Whether this is a default constructor.
2761 (Field::) use readonly public fields instead of properties also.
2763 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
2764 track of static constructors; If none is used, turn on
2765 BeforeFieldInit in the TypeAttributes.
2767 * cs-parser.jay (opt_argument_list): now the return can be null
2768 for the cases where there are no arguments.
2770 (constructor_declarator): If there is no implicit `base' or
2771 `this', then invoke the default parent constructor.
2773 * modifiers.cs (MethodAttr): New static function maps a set of
2774 modifiers flags into a MethodAttributes enum
2775 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
2776 MethodAttr, TypeAttr to represent the various mappings where the
2778 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
2780 2001-08-19 Miguel de Icaza <miguel@ximian.com>
2782 * parameter.cs (GetParameterInfo): Fix bug where there would be no
2785 * interface.cs (PopulateIndexer): Implemented the code generator
2786 for interface indexers.
2788 2001-08-17 Miguel de Icaza <miguel@ximian.com>
2790 * interface.cs (InterfaceMemberBase): Now we track the new status
2793 (PopulateProperty): Implement property population. Woohoo! Got
2794 Methods and Properties going today.
2796 Removed all the properties for interfaces, and replaced them with
2797 `public readonly' fields.
2799 2001-08-16 Miguel de Icaza <miguel@ximian.com>
2801 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
2802 initialize their hashtables/arraylists only when they are needed
2803 instead of doing this always.
2805 * parameter.cs: Handle refs and out parameters.
2807 * cs-parser.jay: Use an ArrayList to construct the arguments
2808 instead of the ParameterCollection, and then cast that to a
2811 * parameter.cs: Drop the use of ParameterCollection and use
2812 instead arrays of Parameters.
2814 (GetParameterInfo): Use the Type, not the Name when resolving
2817 2001-08-13 Miguel de Icaza <miguel@ximian.com>
2819 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
2820 and instead use public readonly fields.
2822 * class.cs: Put back walking code for type containers.
2824 2001-08-11 Miguel de Icaza <miguel@ximian.com>
2826 * class.cs (MakeConstant): Code to define constants.
2828 * rootcontext.cs (LookupType): New function. Used to locate types
2831 2001-08-08 Miguel de Icaza <miguel@ximian.com>
2833 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
2834 this System.Reflection code is. Kudos to Microsoft
2836 * typemanager.cs: Implement a type cache and avoid loading all
2837 types at boot time. Wrap in LookupType the internals. This made
2838 the compiler so much faster. Wow. I rule!
2840 * driver.cs: Make sure we always load mscorlib first (for
2841 debugging purposes, nothing really important).
2843 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
2844 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
2846 * rootcontext.cs: Lookup types on their namespace; Lookup types
2847 on namespaces that have been imported using the `using' keyword.
2849 * class.cs (TypeContainer::TypeAttr): Virtualize.
2850 (Class::TypeAttr): Return attributes suitable for this bad boy.
2851 (Struct::TypeAttr): ditto.
2852 Handle nested classes.
2853 (TypeContainer::) Remove all the type visiting code, it is now
2854 replaced with the rootcontext.cs code
2856 * rootcontext.cs (GetClassBases): Added support for structs.
2858 2001-08-06 Miguel de Icaza <miguel@ximian.com>
2860 * interface.cs, statement.cs, class.cs, parameter.cs,
2861 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
2862 Drop use of TypeRefs, and use strings instead.
2864 2001-08-04 Miguel de Icaza <miguel@ximian.com>
2868 * class.cs (Struct::Struct): set the SEALED flags after
2869 checking the modifiers.
2870 (TypeContainer::TypeAttr): new property, returns the
2871 TypeAttributes for a class.
2873 * cs-parser.jay (type_list): Oops, list production was creating a
2874 new list of base types.
2876 * rootcontext.cs (StdLib): New property.
2877 (GetInterfaceTypeByName): returns an interface by type name, and
2878 encapsulates error handling here.
2879 (GetInterfaces): simplified.
2880 (ResolveTree): Encapsulated all the tree resolution here.
2881 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
2884 * driver.cs: Add support for --nostdlib, to avoid loading the
2886 (Main): Do not put tree resolution here.
2888 * rootcontext.cs: Beginning of the class resolution.
2890 2001-08-03 Miguel de Icaza <miguel@ximian.com>
2892 * rootcontext.cs: Provide better error reporting.
2894 * cs-parser.jay (interface_base): set our $$ to be interfaces.
2896 * rootcontext.cs (CreateInterface): Handle the case where there
2897 are no parent interfaces.
2899 (CloseTypes): Routine to flush types at the end.
2900 (CreateInterface): Track types.
2901 (GetInterfaces): Returns an array of Types from the list of
2904 * typemanager.c (AddUserType): Mechanism to track user types (puts
2905 the type on the global type hash, and allows us to close it at the
2908 2001-08-02 Miguel de Icaza <miguel@ximian.com>
2910 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
2911 RecordInterface instead.
2913 * cs-parser.jay: Updated to reflect changes above.
2915 * decl.cs (Definition): Keep track of the TypeBuilder type that
2916 represents this type here. Not sure we will use it in the long
2917 run, but wont hurt for now.
2919 * driver.cs: Smaller changes to accomodate the new code.
2921 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
2924 * rootcontext.cs (CreateInterface): New method, used to create
2925 the System.TypeBuilder type for interfaces.
2926 (ResolveInterfaces): new entry point to resolve the interface
2928 (CodeGen): Property, used to keep track of the code generator.
2930 2001-07-26 Miguel de Icaza <miguel@ximian.com>
2932 * cs-parser.jay: Add a second production for delegate_declaration
2935 (enum_body): Put an opt_comma here instead of putting it on
2936 enum_body or enum_member_declarations so we can handle trailing
2937 commas on enumeration members. Gets rid of a shift/reduce.
2939 (type_list): Need a COMMA in the middle.
2941 (indexer_declaration): Tell tokenizer to recognize get/set
2943 * Remove old targets.
2945 * Re-add the parser target.
2947 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2949 * cs-parser.jay: Add precendence rules for a number of operators
2950 ot reduce the number of shift/reduce conflicts in the grammar.
2952 2001-07-17 Miguel de Icaza <miguel@ximian.com>
2954 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
2957 Get rid of old crufty code.
2959 * rootcontext.cs: Use this to keep track of the parsed
2960 representation and the defined types available to the program.
2962 * gen-treedump.cs: adjust for new convention.
2964 * type.cs: Split out the type manager, and the assembly builder
2967 * typemanager.cs: the type manager will live here now.
2969 * cil-codegen.cs: And the code generator here.
2971 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
2973 * makefile: Fixed up for easy making.
2975 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2977 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
2980 (unary_expression): Expand pre_increment_expression and
2981 post_decrement_expression to reduce a shift/reduce.
2983 2001-07-11 Simon Cozens
2985 * cs-tokenizer.cs: Hex numbers should begin with a 0.
2987 Improve allow_keyword_as_indent name.
2989 2001-06-19 Miguel de Icaza <miguel@ximian.com>
2991 * Adjustments for Beta2.
2993 2001-06-13 Miguel de Icaza <miguel@ximian.com>
2995 * decl.cs: Added `Define' abstract method.
2996 (InTransit): new property, used to catch recursive definitions.
2998 * interface.cs: Implement `Define'.
3000 * modifiers.cs: Map Modifiers.constants to
3001 System.Reflection.TypeAttribute flags.
3003 * class.cs: Keep track of types and user-defined types.
3004 (BuilderInit): New method for creating an assembly
3005 (ResolveType): New function to launch the resolution process, only
3006 used by interfaces for now.
3008 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
3009 that are inserted into the name space.
3011 2001-06-08 Miguel de Icaza <miguel@ximian.com>
3013 * ARGH. I have screwed up my tree so many times due to the use of
3014 rsync rather than using CVS. Going to fix this at once.
3016 * driver.cs: Objetify driver. Load assemblies, use assemblies to
3019 2001-06-07 Miguel de Icaza <miguel@ximian.com>
3021 * Experiment successful: Use System.Type rather that our own
3024 2001-05-25 Miguel de Icaza <miguel@ximian.com>
3026 * cs-parser.jay: Removed nsAliases from here.
3028 Use new namespaces, handle `using XXX;'
3030 * namespace.cs: Reimplemented namespace handling, use a recursive
3031 definition of the class. Now we can keep track of using clauses
3032 and catch invalid using clauses.
3034 2001-05-24 Miguel de Icaza <miguel@ximian.com>
3036 * gen-treedump.cs: Adapted for all the renaming.
3038 * expression.cs (Expression): this class now has a Type property
3039 which returns an expression Type.
3041 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
3042 `Type', as this has a different meaning now in the base
3044 2001-05-22 Miguel de Icaza <miguel@ximian.com>
3046 * interface.cs, class.cs: Removed from all the sources the
3047 references to signature computation, as we can not do method
3048 signature computation during the parsing time, as we are not
3049 trying to solve at that point distinguishing:
3053 void a (NS.Blah x) {}
3056 Which depending on the context might be valid or not, as we do not
3057 know if Blah is the same thing as NS.Blah at that point.
3059 * Redid everything so the code uses TypeRefs now instead of
3060 Types. TypeRefs are just temporary type placeholders, that need
3061 to be resolved. They initially have a pointer to a string and the
3062 current scope in which they are used. This is used later by the
3063 compiler to resolve the reference to an actual Type.
3065 * DeclSpace is no longer a CIR.Type, and neither are
3066 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
3067 are all DeclSpaces, but no Types.
3069 * type.cs (TypeRefManager): This implements the TypeRef manager,
3070 which keeps track of all the types that need to be resolved after
3071 the parsing has finished.
3073 2001-05-13 Miguel de Icaza <miguel@ximian.com>
3075 * ARGH. We are going to have to store `foreach' as a class rather
3076 than resolving it, as we need to verify error 1579 after name
3077 resolution. *OR* we could keep a flag that says `This request to
3078 IEnumerator comes from a foreach statement' which we can then use
3079 to generate the error.
3081 2001-05-10 Miguel de Icaza <miguel@ximian.com>
3083 * class.cs (TypeContainer.AddMethod): we now add methods to the
3084 MethodGroup instead of the method hashtable.
3086 * expression.cs: Add MethodGroup abstraction, which gets us one
3087 step closer to the specification in the way we handle method
3090 * cs-parser.jay (primary_expression): qualified_identifier now
3091 tried to match up an identifier to a local variable reference or
3092 to a parameter reference.
3094 current_local_parameters is now a parser global variable that
3095 points to the current parameters for the block, used during name
3098 (property_declaration): Now creates an implicit `value' argument to
3101 2001-05-09 Miguel de Icaza <miguel@ximian.com>
3103 * parameter.cs: Do not use `param' arguments as part of the
3104 signature, per the spec.
3106 2001-05-08 Miguel de Icaza <miguel@ximian.com>
3108 * decl.cs: Base class for classes, structs and interfaces. This
3109 is the "Declaration Space"
3111 * cs-parser.jay: Use CheckDef for checking declaration errors
3112 instead of having one on each function.
3114 * class.cs: Factor out some code for handling error handling in
3115 accordance to the "Declarations" section in the "Basic Concepts"
3116 chapter in the ECMA C# spec.
3118 * interface.cs: Make all interface member classes derive from
3119 InterfaceMemberBase.
3121 2001-05-07 Miguel de Icaza <miguel@ximian.com>
3123 * Many things: all interfaces are parsed and generated in
3124 gen-treedump. Support for member variables, constructors,
3125 destructors, properties, constants is there.
3127 Beginning of the IL backend, but very little done, just there for
3130 2001-04-29 Miguel de Icaza <miguel@ximian.com>
3132 * cs-parser.jay: Fix labeled statement.
3134 * cs-tokenizer.cs (escape): Escape " and ' always.
3135 ref_line, ref_name: keep track of the line/filename as instructed
3136 by #line by the compiler.
3139 2001-04-27 Miguel de Icaza <miguel@ximian.com>
3141 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
3142 to match the values in System.CodeDOM.
3144 Divid renamed to Divide.
3146 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
3148 (Statements.set): remove.
3150 * System.CodeDOM/CodeCatchClause.cs: always have a valid
3153 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
3154 falseStatements always have valid values.
3156 * cs-parser.jay: Use System.CodeDOM now.
