786 * class.cs (Method, Constructor, Property): Pass expected return
789 2001-10-09 Miguel de Icaza <miguel@ximian.com>
791 * expression.cs: Make DoResolve take an EmitContext instead of a
794 Replaced `l' and `location' for `loc', for consistency.
796 (Error, Warning): Remove unneeded Tc argument.
798 * assign.cs, literal.cs, constant.cs: Update to new calling
801 * codegen.cs: EmitContext now contains a flag indicating whether
802 code is being generated in a static method or not.
804 * cs-parser.jay: DecomposeQI, new function that replaces the old
805 QualifiedIdentifier. Now we always decompose the assembled
806 strings from qualified_identifier productions into a group of
809 2001-10-08 Miguel de Icaza <miguel@ximian.com>
811 * rootcontext.cs: Deal with field-less struct types correctly now
812 by passing the size option to Define Type.
814 * class.cs: Removed hack that created one static field.
816 2001-10-07 Miguel de Icaza <miguel@ximian.com>
818 * statement.cs: Moved most of the code generation here.

831 and start performing checks according to the spec.
833 2001-10-07 Ravi Pratap <ravi@ximian.com>

836 rank_specifiers instead.
838 (rank_specifiers): Change the order in which the rank specifiers are stored
840 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
842 * expression.cs (ElementAccess): Implement the LValue interface too.
844 2001-10-06 Ravi Pratap <ravi@ximian.com>
846 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
847 except that user defined conversions are not included.
849 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
850 perform the conversion of the return type, if necessary.
852 (New::DoResolve): Check whether we are creating an array or an object
853 and accordingly do the needful.
855 (New::Emit): Same here.

868 * cs-parser.jay: Added support for try/catch/finalize.
870 * class.cs: Catch static methods having the flags override,
873 * expression.cs (UserCast): This user cast was not really doing
874 what it was supposed to do. Which is to be born in fully resolved
875 state. Parts of the resolution were being performed at Emit time!
879 2001-10-05 Miguel de Icaza <miguel@ximian.com>
881 * expression.cs: Implicity convert the result from UserCast.
883 2001-10-05 Ravi Pratap <ravi@ximian.com>
885 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
886 prevented it from working correctly.

889 merely ConvertImplicit.
891 2001-10-05 Miguel de Icaza <miguel@ximian.com>
893 * typemanager.cs: Make the LookupTypeContainer function static,
894 and not per-instance.
896 * class.cs: Make static FindMembers (the one that takes a Type
899 * codegen.cs: Add EmitForeach here.
901 * cs-parser.jay: Make foreach a toplevel object instead of the
902 inline expansion, as we need to perform semantic analysis on it.
904 2001-10-05 Ravi Pratap <ravi@ximian.com>
906 * expression.cs (Expression::ImplicitUserConversion): Rename to
907 UserDefinedConversion.

921 * expression.cs (Cast): Record location info.
923 (Expression::ConvertExplicit): Take location argument.
925 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
926 to determine if we are doing explicit conversions.
928 (UserCast::Emit): Update accordingly.
930 (Expression::ConvertExplicit): Report an error if everything fails.
932 * ../errors/cs0030.cs : Add.
934 2001-10-04 Miguel de Icaza <miguel@ximian.com>
936 * modifiers.cs: If the ABSTRACT keyword is present, also set the
937 virtual and newslot bits.
939 * class.cs (TypeContainer::RegisterRequiredImplementations):
940 Record methods we need.
942 (TypeContainer::MakeKey): Helper function to make keys for
943 MethodBases, since the Methodbase key is useless.
945 (TypeContainer::Populate): Call RegisterRequiredImplementations
946 before defining the methods.
948 Create a mapping for method_builders_to_methods ahead of time
949 instead of inside a tight loop.
951 (::RequireMethods): Accept an object as the data to set into the
952 hashtable so we can report interface vs abstract method mismatch.
954 2001-10-03 Miguel de Icaza <miguel@ximian.com>
956 * report.cs: Make all of it static.
958 * rootcontext.cs: Drop object_type and value_type computations, as
959 we have those in the TypeManager anyways.
961 Drop report instance variable too, now it is a global.
963 * driver.cs: Use try/catch on command line handling.
965 Add --probe option to debug the error reporting system with a test
968 * report.cs: Add support for exiting program when a probe
969 condition is reached.
971 2001-10-03 Ravi Pratap <ravi@ximian.com>
973 * expression.cs (Binary::DoNumericPromotions): Fix the case when
974 we do a forcible conversion regardless of type, to check if
975 ForceConversion returns a null.
977 (Binary::error19): Use location to report error.
979 (Unary::error23): Use location here too.
981 * ../errors/cs0019.cs : Check in.
983 * ../errors/cs0023.cs : Check in.
985 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
986 case of a non-null MethodInfo object with a length of 0 !
988 (Binary::ResolveOperator): Flag error if overload resolution fails to find
989 an applicable member - according to the spec :-)
990 Also fix logic to find members in base types.
992 (Unary::ResolveOperator): Same here.
994 (Unary::report23): Change name to error23 and make first argument a TypeContainer
995 as I was getting thoroughly confused between this and error19 :-)
997 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
998 (::FindMostEncompassedType): Implement.
999 (::FindMostEncompassingType): Implement.
1000 (::StandardConversionExists): Implement.
1002 (UserImplicitCast): Re-vamp. We now need info about most specific
1003 source and target types so that we can do the necessary conversions.
1005 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
1006 mathematical union with no duplicates.
1008 2001-10-03 Miguel de Icaza <miguel@ximian.com>
1010 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
1011 in order from base classes to child classes, so that we can in
1012 child classes look up in our parent for method names and
1013 attributes (required for handling abstract, virtual, new, override
1014 constructs: we need to instrospect our base class, and if we dont
1015 populate the classes in order, the introspection might be
1016 incorrect. For example, a method could query its parent before
1017 the parent has any methods and would determine that the parent has
1018 no abstract methods (while it could have had them)).
1020 (RootContext::CreateType): Record the order in which we define the
1023 2001-10-02 Miguel de Icaza <miguel@ximian.com>
1025 * class.cs (TypeContainer::Populate): Also method definitions can
1026 fail now, keep track of this.
1028 (TypeContainer::FindMembers): Implement support for
1029 DeclaredOnly/noDeclaredOnly flag.
1031 (Constructor::Emit) Return the ConstructorBuilder.

1041 not marked abstract or extern).
1043 * expression.cs (TypeOf::Emit): Implement.
1045 * typemanager.cs: runtime_handle_type, new global type.
1047 * class.cs (Property::Emit): Generate code for properties.
1049 2001-10-02 Ravi Pratap <ravi@ximian.com>
1051 * expression.cs (Unary::ResolveOperator): Find operators on base type
1052 too - we now conform exactly to the spec.
1054 (Binary::ResolveOperator): Same here.
1056 * class.cs (Operator::Define): Fix minor quirk in the tests.
1058 * ../errors/cs0215.cs : Added.
1060 * ../errors/cs0556.cs : Added.
1062 * ../errors/cs0555.cs : Added.
1064 2001-10-01 Miguel de Icaza <miguel@ximian.com>
1066 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
1067 single integer which is really efficient
1069 2001-10-01 Ravi Pratap <ravi@ximian.com>
1071 * expression.cs (Expression::ImplicitUserConversion): Use location
1072 even in the case when we are examining True operators.
1074 * class.cs (Operator::Define): Perform extensive checks to conform
1075 with the rules for operator overloading in the spec.
1077 * expression.cs (Expression::ImplicitReferenceConversion): Implement
1078 some of the other conversions mentioned in the spec.

1083 (cloneable_interface): For System.ICloneable interface.
1085 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
1086 we start resolving the tree and populating types.
1088 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
1090 2001-10-01 Miguel de Icaza <miguel@ximian.com>
1092 * expression.cs (Expression::ExprClassFromMemberInfo,
1093 Expression::Literalize): Create literal expressions from
1094 FieldInfos which are literals.
1096 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
1097 type casts, because they were wrong. The test suite in tests
1100 (ImplicitNumericConversion): ushort to ulong requires a widening
1103 Int32 constant to long requires widening cast as well.
1105 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
1106 for integers because the type on the stack is not i4.
1108 2001-09-30 Miguel de Icaza <miguel@ximian.com>
1110 * expression.cs (report118): require location argument.
1112 * parameter.cs: Do not dereference potential null value.
1114 * class.cs: Catch methods that lack the `new' keyword when
1115 overriding a name. Report warnings when `new' is used without
1116 anything being there to override.
1118 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
1120 * class.cs: Only add constructor to hashtable if it is non-null
1121 (as now constructors can fail on define).
1123 (TypeManager, Class, Struct): Take location arguments.
1125 Catch field instance initialization in structs as errors.
1127 accepting_filter: a new filter for FindMembers that is static so
1128 that we dont create an instance per invocation.
1130 (Constructor::Define): Catch errors where a struct constructor is
1133 * cs-parser.jay: Pass location information for various new
1136 * delegate.cs (Delegate): take a location argument.
1138 * driver.cs: Do not call EmitCode if there were problesm in the
1139 Definition of the types, as many Builders wont be there.
1141 * decl.cs (Decl::Decl): Require a location argument.
1143 * cs-tokenizer.cs: Handle properly hex constants that can not fit
1144 into integers, and find the most appropiate integer for it.
1146 * literal.cs: Implement ULongLiteral.
1148 * rootcontext.cs: Provide better information about the location of
1149 failure when CreateType fails.
1151 2001-09-29 Miguel de Icaza <miguel@ximian.com>
1153 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
1156 * expression.cs (Binary::CheckShiftArguments): Add missing type
1158 (Binary::ResolveOperator): Add type to the logical and and logical
1159 or, Bitwise And/Or and Exclusive Or code paths, it was missing
1162 (Binary::DoNumericPromotions): In the case where either argument
1163 is ulong (and most signed types combined with ulong cause an
1164 error) perform implicit integer constant conversions as well.
1166 2001-09-28 Miguel de Icaza <miguel@ximian.com>
1168 * expression.cs (UserImplicitCast): Method should always be
1170 (Invocation::BetterConversion): Simplified test for IntLiteral.
1172 (Expression::ImplicitNumericConversion): Split this routine out.
1173 Put the code that performs implicit constant integer conversions
1176 (Expression::Resolve): Become a wrapper around DoResolve so we can
1177 check eclass and type being set after resolve.
1179 (Invocation::Badness): Remove this dead function
1181 (Binary::ResolveOperator): Do not compute the expensive argumnets
1182 unless we have a union for it.
1184 (Probe::Emit): Is needs to do an isinst and then
1185 compare against null.
1187 (::CanConvert): Added Location argument. If the Location argument
1188 is null (Location.Null), then we do not report errors. This is
1189 used by the `probe' mechanism of the Explicit conversion. We do
1190 not want to generate an error for something that the user
1191 explicitly requested to be casted. But the pipeline for an
1192 explicit cast first tests for potential implicit casts.
1194 So for now, if the Location is null, it means `Probe only' to
1195 avoid adding another argument. Might have to revise this
1198 (ClassCast): New class used to type cast objects into arbitrary
1199 classes (used in Explicit Reference Conversions).
1201 Implement `as' as well.
1203 Reverted all the patches from Ravi below: they were broken:
1205 * The use of `level' as a mechanism to stop recursive
1206 invocations is wrong. That was there just to catch the
1207 bug with a strack trace but not as a way of addressing
1210 To fix the problem we have to *understand* what is going
1211 on and the interactions and come up with a plan, not
1212 just get things going.
1214 * The use of the type conversion cache that I proposed
1215 last night had an open topic: How does this work across
1216 protection domains. A user defined conversion might not
1217 be public in the location where we are applying the
1218 conversion, a different conversion might be selected
1219 (ie, private A->B (better) but public B->A (worse),
1220 inside A, A->B applies, but outside it, B->A will
1223 * On top of that (ie, even if the above is solved),
1224 conversions in a cache need to be abstract. Ie, `To
1225 convert from an Int to a Short use an OpcodeCast', not
1226 `To convert from an Int to a Short use the OpcodeCast on
1227 the variable 5' (which is what this patch was doing).
1229 2001-09-28 Ravi Pratap <ravi@ximian.com>
1231 * expression.cs (Invocation::ConversionExists): Re-write to use
1232 the conversion cache
1234 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
1235 cache all conversions done, not just user-defined ones.
1237 (Invocation::BetterConversion): The real culprit. Use ConversionExists
1238 to determine if a conversion exists instead of acutually trying to
1239 perform the conversion. It's faster too.
1241 (Expression::ConvertExplicit): Modify to use ConversionExists to check
1242 and only then attempt the implicit conversion.
1244 2001-09-28 Ravi Pratap <ravi@ximian.com>
1246 * expression.cs (ConvertImplicit): Use a cache for conversions
1247 already found. Check level of recursion and bail out if necessary.
1249 2001-09-28 Miguel de Icaza <miguel@ximian.com>
1251 * typemanager.cs (string_concat_string_string, string_concat_object_object):
1252 Export standard methods that we expect for string operations.
1254 * statement.cs (Block::UsageWarning): Track usage of variables and
1255 report the errors for not used variables.
1257 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
1260 2001-09-27 Miguel de Icaza <miguel@ximian.com>
1262 * codegen.cs: remove unnneded code
1264 * expression.cs: Removed BuiltinTypeAccess class
1266 Fix the order in which implicit conversions are
1269 The previous fixed dropped support for boxed conversions (adding a
1270 test to the test suite now)
1272 (UserImplicitCast::CanConvert): Remove test for source being null,
1273 that code is broken. We should not feed a null to begin with, if
1274 we do, then we should track the bug where the problem originates
1275 and not try to cover it up here.
1277 Return a resolved expression of type UserImplicitCast on success
1278 rather than true/false. Ravi: this is what I was talking about,
1279 the pattern is to use a static method as a "constructor" for
1282 Also, do not create arguments until the very last minute,
1283 otherwise we always create the arguments even for lookups that
1284 will never be performed.
1286 (UserImplicitCast::Resolve): Eliminate, objects of type
1287 UserImplicitCast are born in a fully resolved state.
1289 * typemanager.cs (InitCoreTypes): Init also value_type
1292 * expression.cs (Cast::Resolve): First resolve the child expression.
1294 (LValue): Add new method AddressOf to be used by
1297 Change the argument of Store to take an EmitContext instead of an
1298 ILGenerator, because things like FieldExpr need to be able to call
1299 their children expression to generate the instance code.
1301 (Expression::Error, Expression::Warning): Sugar functions for
1304 (Expression::MemberLookup): Accept a TypeContainer instead of a
1305 Report as the first argument.
1307 (Expression::ResolvePrimary): Killed. I still want to improve
1308 this as currently the code is just not right.
1310 (Expression::ResolveMemberAccess): Simplify, but it is still
1313 (Unary::Resolve): Catch errors in AddressOf operators.
1315 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
1316 index to a byte for the short-version, or the compiler will choose
1317 the wrong Emit call, which generates the wrong data.
1319 (ParameterReference::Emit, ::Store): same.
1321 (FieldExpr::AddressOf): Implement.
1323 * typemanager.cs: TypeManager: made public variable instead of
1326 * driver.cs: document --fatal.
1328 * report.cs (ErrorMessage, WarningMessage): new names for the old
1329 Error and Warning classes.
1331 * cs-parser.jay (member_access): Turn built-in access to types
1332 into a normal simplename
1334 2001-09-27 Ravi Pratap <ravi@ximian.com>
1336 * expression.cs (Invocation::BetterConversion): Fix to cope
1337 with q being null, since this was introducing a bug.
1339 * expression.cs (ConvertImplicit): Do built-in conversions first.
1341 2001-09-27 Ravi Pratap <ravi@ximian.com>
1343 * expression.cs (UserImplicitCast::Resolve): Fix bug.
1345 2001-09-27 Ravi Pratap <ravi@ximian.com>
1347 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
1348 I had introduced long ago (what's new ?).
1350 * expression.cs (UserImplicitCast::CanConvert): Static method to do
1351 the work of all the checking.
1352 (ConvertImplicit): Call CanConvert and only then create object if necessary.
1353 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
1355 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
1356 that is the right way.
1358 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
1359 overloading resolution. Use everywhere instead of cutting and pasting code.
1361 (Binary::ResolveOperator): Use MakeUnionSet.
1363 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
1364 we have to convert to bool types. Not complete yet.
1366 2001-09-27 Miguel de Icaza <miguel@ximian.com>
1368 * typemanager.cs (TypeManager::CSharpName): support ushort.
1370 * expression.cs (Expression::TryImplicitIntConversion): Attempts
1371 to provide an expression that performsn an implicit constant int
1372 conversion (section 6.1.6).
1373 (Expression::ConvertImplicitRequired): Reworked to include
1374 implicit constant expression conversions.
1376 (Expression::ConvertNumericExplicit): Finished.
1378 (Invocation::Emit): If InstanceExpression is null, then it means
1379 that we perform a call on this.
1381 2001-09-26 Miguel de Icaza <miguel@ximian.com>
1383 * expression.cs (Unary::Emit): Remove some dead code.
1384 (Probe): Implement Resolve and Emit for `is'.
1385 (Expression::ConvertImplicitRequired): Attempt to do constant
1386 expression conversions here. Maybe should be moved to
1387 ConvertImplicit, but I am not sure.
1388 (Expression::ImplicitLongConstantConversionPossible,
1389 Expression::ImplicitIntConstantConversionPossible): New functions
1390 that tell whether is it possible to apply an implicit constant
1391 expression conversion.
1393 (ConvertNumericExplicit): Started work on explicit numeric
1396 * cs-parser.jay: Update operator constants.
1398 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
1399 (Parameters::GetSignature): Hook up VerifyArgs here.
1400 (Parameters::VerifyArgs): Verifies that no two arguments have the
1403 * class.cs (Operator): Update the operator names to reflect the
1404 ones that the spec expects (as we are just stringizing the
1407 * expression.cs (Unary::ResolveOperator): Fix bug: Use
1408 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
1409 previous usage did only work for our methods.
1410 (Expression::ConvertImplicit): Handle decimal implicit numeric
1411 conversions as well.
1412 (Expression::InternalTypeConstructor): Used to invoke constructors
1413 on internal types for default promotions.
1415 (Unary::Emit): Implement special handling for the pre/post
1416 increment/decrement for overloaded operators, as they need to have
1417 the same semantics as the other operators.
1419 (Binary::ResolveOperator): ditto.
1420 (Invocation::ConversionExists): ditto.
1421 (UserImplicitCast::Resolve): ditto.
1423 2001-09-26 Ravi Pratap <ravi@ximian.com>
1425 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded
1426 operator, return after emitting body. Regression tests pass again !
1428 * expression.cs (ConvertImplicit): Take TypeContainer as first argument
1429 (Unary::ForceConversion, Binary::ForceConversion): Ditto.
1430 (Invocation::OverloadResolve): Ditto.
1431 (Invocation::BetterFunction, BetterConversion, ConversionExists): Ditto.
1433 * everywhere : update calls to the above methods accordingly.
1435 2001-09-26 Miguel de Icaza <miguel@ximian.com>
1437 * assign.cs (Assign): Make it inherit from ExpressionStatement.
1439 * expression.cs (ExpressionStatement): New base class used for
1440 expressions that can appear in statements, so that we can provide
1441 an alternate path to generate expression that do not leave a value
1444 (Expression::Emit, and all the derivatives): We no longer return
1445 whether a value is left on the stack or not. Every expression

1465 to find "op_Implicit", not "implicit" ;-)
1466 (UserImplicitCast): New class to take care of user-defined implicit conversions.

1542 * typemanager.cs: declare and load enum_type, delegate_type and
1545 * expression.cs (Expression::Emit): Now emit returns a value that

1651 (Unary::ForceConversion): Copy and Paste !
1653 * class.cs (Operator::Define): Fix a small bug for the case when we have
1656 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
1657 for the inbuilt operators. Only overloading works for now ;-)
1659 2001-09-18 Miguel de Icaza <miguel@ximian.com>
1661 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
1662 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

1677 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
1678 the last instruction contains a return opcode to avoid generating

1683 initializer for static and instance variables.
1684 (Constructor::Emit): Allow initializer to be null in the case of
1685 static constructors. Only emit initializer for instance

1703 initializers if none was specified.
1704 Catch the fact that constructors should not have parameters.
1706 * class.cs: Do not emit parent class initializers for static
1707 constructors, that should be flagged as an error.
1709 2001-09-18 Ravi Pratap <ravi@ximian.com>
1711 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.

1741 (Expression::MemberLookup): Provide a version that allows to
1742 specify the MemberTypes and BindingFlags.
1744 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
1745 so it was not fetching variable information from outer blocks.
1747 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
1748 Beforefieldinit as it was buggy.
1750 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
1753 * class.cs (Constructor::Emit): Only emit if block is not null.

1860 * driver.cs: Added --parse option that only parses its input files
1863 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
1864 incorrect. IsTopLevel is not used to tell whether an object is

1866 root_types). But to see if this is a top-level *class* (not
1867 necessarly our "toplevel" container).
1869 2001-09-14 Ravi Pratap <ravi@ximian.com>
1871 * enum.cs (Enum::Define): Modify to call the Lookup method on the

1877 Modifiers.TypeAttr. This should just be a call to that method.

1887 * modifiers.cs (FieldAttr): Re-write.

1893 * modifiers.cs (MethodAttr): Re-write.
1894 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
1896 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent

1899 2001-09-13 Miguel de Icaza <miguel@ximian.com>
1901 * expression.cs (MemberLookup): Fruitless attempt to lookup
1902 constructors. Maybe I need to emit default constructors? That

1904 (Invocation::OverloadResolve): Cope with Arguments == null.
1905 (Invocation::EmitArguments): new function, shared by the new
1907 (Invocation::Emit): Handle static and instance methods. Emit

1929 (Populate): Only initialize method_builders_to_methods once.
1931 * expression.cs (PropertyExpr): Initialize type from the
1934 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

1939 (Binary::ResolveOperator): Set the return type to boolean for
1940 comparission operators
1942 * typemanager.cs: Remove debugging print code.
1944 (Invocation::Resolve): resolve type.
1946 * class.cs: Allocate a MemberInfo of the correct size, as the code
1947 elsewhere depends on the test to reflect the correct contents.
1949 (Method::) Keep track of parameters, due to System.Reflection holes
1951 (TypeContainer::Populate): Keep track of MethodBuilders to Method
1954 (TypeContainer::FindMembers): Use ArrayList and then copy an array
1955 of the exact size and return that.
1957 (Class::LookupMethodByBuilder): New function that maps
1958 MethodBuilders to its methods. Required to locate the information
1959 on methods because System.Reflection bit us again.
1961 * support.cs: New file, contains an interface ParameterData and
1962 two implementations: ReflectionParameters and InternalParameters
1963 used to access Parameter information. We will need to grow this
1966 * expression.cs (Invocation::GetParameterData): implement a cache
1967 and a wrapper around the ParameterData creation for methods.
1968 (Invocation::OverloadResolve): Use new code.
1970 2001-09-13 Ravi Pratap <ravi@ximian.com>

2024 2001-09-12 Ravi Pratap <ravi@ximian.com>
2026 * class.cs (TypeContainer::FindMembers): Method which does exactly
2027 what Type.FindMembers does, only we don't have to use reflection. No
2030 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
2031 typecontainer objects as we need to get at them.
2032 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.
2034 * rootcontext.cs : Correspondingly modify called to AddUserType to pass the
2035 typecontainer object.
2037 * expression.cs (MemberLookup): Modify signature to take a RootContext object instead
2038 of just a Report object.

2059 (Event::Define): Ditto.
2060 (Property::Define): Ditto.
2062 2001-09-10 Ravi Pratap <ravi@ximian.com>

2067 (Operator.OperatorMethodBuilder): New member to hold the method builder
2068 for the operator we are defining.

2074 addOn_ and removeOn_
2076 * genericparser.cs (GenericParser::error): Overloaded method to handle the case

2127 already might have something already fully qualified like
2128 'System.Console.WriteLine'

2277 * expression.cs, literal.cs, assign.cs, constant.cs: All `Resolve'
2278 methods inherited from Expression return now an Expression. This
2279 will is used during the tree rewriting as we resolve them during
2282 (Expression::MemberLookup): Implements the MemberLookup (7.3) from
2283 the spec. Missing entirely is the information about
2284 accessability of elements of it.

2455 and re-write the code in the actions to extract the specific and
2456 general catch clauses by being a little smart ;-)
2458 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
2459 Hooray, try and catch statements parse fine !
2461 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2463 * statement.cs (Block::GetVariableType): Fix logic to extract the type
2464 string from the hashtable of variables.
2466 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did

2468 (catch_clauses): Fixed gross error which made Key and Value of the
2469 DictionaryEntry the same : $1 !!
2471 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
2473 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
2475 * cs-parser.jay (event_declaration): Correct to remove the semicolon

2482 (indexer_declarator): Implement actions.
2483 (parsing_indexer): New local boolean used to keep track of whether

2511 concatenating all the commas together, just as they appear.
2512 (opt_dim_separators): Modify accordingly
2513 (rank_specifiers): Update accordingly. Basically do the same
2514 thing - instead, collect the brackets here.
2515 (opt_rank_sepcifiers): Modify accordingly.

2517 instead of ignoring the rank_specifiers.
2518 (expression_list): Implement to collect the expressions

2523 (opt_array_initializer): Modify accordingly.

2544 * typemanager.cs (InitCoreTypes): Initialize the various core
2545 types after we have populated the type manager with the user
2546 defined types (this distinction will be important later while
2547 compiling corlib.dll)
2549 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
2550 on Expression Classification. Now all expressions have a method
2551 `Resolve' and a method `Emit'.

2554 generation from working. Also add some temporary debugging
2557 2001-08-24 Miguel de Icaza <miguel@ximian.com>
2559 * codegen.cs: Lots of code generation pieces. This is only the
2560 beginning, will continue tomorrow with more touches of polish. We
2561 handle the fundamentals of if, while, do, for, return. Others are
2562 trickier and I need to start working on invocations soon.
2564 * gen-treedump.cs: Bug fix, use s.Increment here instead of
2567 * codegen.cs (EmitContext): New struct, used during code
2568 emission to keep a context. Most of the code generation will be

2588 * class.cs: Drop support for MethodGroups here, delay until
2590 (Method::): Applied the same simplification that I did before, and
2591 move from Properties to public readonly fields.
2592 (Method::ParameterTypes): Returns the parameter types for the
2593 function, and implements a cache that will be useful later when I
2594 do error checking and the semantic analysis on the methods is
2596 (Constructor::GetCallingConvention): Renamed from CallingConvetion
2597 and made a method, optional argument tells whether this is a class
2598 or a structure to apply the `has-this' bit.
2599 (Method::GetCallingConvention): Implement, returns the calling
2601 (Method::Define): Defines the type, a second pass is performed
2602 later to populate the methods.

2623 (TypeContainer::AddConstructor): Keep track of default constructor
2624 and the default static constructor.
2626 (Constructor::) Another class that starts using `public readonly'
2627 instead of properties.
2629 (Constructor::IsDefault): Whether this is a default constructor.
2631 (Field::) use readonly public fields instead of properties also.
2633 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
2634 track of static constructors; If none is used, turn on
2635 BeforeFieldInit in the TypeAttributes.
2637 * cs-parser.jay (opt_argument_list): now the return can be null
2638 for the cases where there are no arguments.
2640 (constructor_declarator): If there is no implicit `base' or
2641 `this', then invoke the default parent constructor.
2643 * modifiers.cs (MethodAttr): New static function maps a set of
2644 modifiers flags into a MethodAttributes enum
2645 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
2646 MethodAttr, TypeAttr to represent the various mappings where the
2648 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
2650 2001-08-19 Miguel de Icaza <miguel@ximian.com>

2667 `public readonly' fields.
2669 2001-08-16 Miguel de Icaza <miguel@ximian.com>
2671 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
2672 initialize their hashtables/arraylists only when they are needed
2673 instead of doing this always.
2675 * parameter.cs: Handle refs and out parameters.
2677 * cs-parser.jay: Use an ArrayList to construct the arguments
2678 instead of the ParameterCollection, and then cast that to a
2681 * parameter.cs: Drop the use of ParameterCollection and use
2682 instead arrays of Parameters.
2684 (GetParameterInfo): Use the Type, not the Name when resolving
2687 2001-08-13 Miguel de Icaza <miguel@ximian.com>

2704 this System.Reflection code is. Kudos to Microsoft
2706 * typemanager.cs: Implement a type cache and avoid loading all
2707 types at boot time. Wrap in LookupType the internals. This made
2708 the compiler so much faster. Wow. I rule!
2710 * driver.cs: Make sure we always load mscorlib first (for
2711 debugging purposes, nothing really important).
2713 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
2714 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
2716 * rootcontext.cs: Lookup types on their namespace; Lookup types
2717 on namespaces that have been imported using the `using' keyword.
2719 * class.cs (TypeContainer::TypeAttr): Virtualize.
2720 (Class::TypeAttr): Return attributes suitable for this bad boy.
2721 (Struct::TypeAttr): ditto.
2722 Handle nested classes.
2723 (TypeContainer::) Remove all the type visiting code, it is now
2724 replaced with the rootcontext.cs code
2726 * rootcontext.cs (GetClassBases): Added support for structs.
2728 2001-08-06 Miguel de Icaza <miguel@ximian.com>
2730 * interface.cs, statement.cs, class.cs, parameter.cs,
2731 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
2732 Drop use of TypeRefs, and use strings instead.
2734 2001-08-04 Miguel de Icaza <miguel@ximian.com>
2738 * class.cs (Struct::Struct): set the SEALED flags after
2739 checking the modifiers.
2740 (TypeContainer::TypeAttr): new property, returns the
2741 TypeAttributes for a class.
2743 * cs-parser.jay (type_list): Oops, list production was creating a
2744 new list of base types.
2746 * rootcontext.cs (StdLib): New property.
2747 (GetInterfaceTypeByName): returns an interface by type name, and
2748 encapsulates error handling here.
2749 (GetInterfaces): simplified.
2750 (ResolveTree): Encapsulated all the tree resolution here.
2751 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
2754 * driver.cs: Add support for --nostdlib, to avoid loading the
2756 (Main): Do not put tree resolution here.
2758 * rootcontext.cs: Beginning of the class resolution.
2760 2001-08-03 Miguel de Icaza <miguel@ximian.com>
2762 * rootcontext.cs: Provide better error reporting.
2764 * cs-parser.jay (interface_base): set our $$ to be interfaces.
2766 * rootcontext.cs (CreateInterface): Handle the case where there
2767 are no parent interfaces.
2769 (CloseTypes): Routine to flush types at the end.
2770 (CreateInterface): Track types.
2771 (GetInterfaces): Returns an array of Types from the list of
2774 * typemanager.c (AddUserType): Mechanism to track user types (puts
2775 the type on the global type hash, and allows us to close it at the
2778 2001-08-02 Miguel de Icaza <miguel@ximian.com>
2780 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
2781 RecordInterface instead.
2783 * cs-parser.jay: Updated to reflect changes above.
2785 * decl.cs (Definition): Keep track of the TypeBuilder type that
2786 represents this type here. Not sure we will use it in the long
2787 run, but wont hurt for now.
2789 * driver.cs: Smaller changes to accomodate the new code.
2791 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
2794 * rootcontext.cs (CreateInterface): New method, used to create
2795 the System.TypeBuilder type for interfaces.
2796 (ResolveInterfaces): new entry point to resolve the interface
2798 (CodeGen): Property, used to keep track of the code generator.
2800 2001-07-26 Miguel de Icaza <miguel@ximian.com>
2802 * cs-parser.jay: Add a second production for delegate_declaration
2805 (enum_body): Put an opt_comma here instead of putting it on
2806 enum_body or enum_member_declarations so we can handle trailing
2807 commas on enumeration members. Gets rid of a shift/reduce.
2809 (type_list): Need a COMMA in the middle.
2811 (indexer_declaration): Tell tokenizer to recognize get/set
2813 * Remove old targets.
2815 * Re-add the parser target.
2817 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2819 * cs-parser.jay: Add precendence rules for a number of operators
2820 ot reduce the number of shift/reduce conflicts in the grammar.
2822 2001-07-17 Miguel de Icaza <miguel@ximian.com>
2824 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
2827 Get rid of old crufty code.
2829 * rootcontext.cs: Use this to keep track of the parsed
2830 representation and the defined types available to the program.
2832 * gen-treedump.cs: adjust for new convention.
2834 * type.cs: Split out the type manager, and the assembly builder
2837 * typemanager.cs: the type manager will live here now.
2839 * cil-codegen.cs: And the code generator here.
2841 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
2843 * makefile: Fixed up for easy making.
2845 2001-07-13 Simon Cozens <simon@simon-cozens.org>
2847 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
2850 (unary_expression): Expand pre_increment_expression and
2851 post_decrement_expression to reduce a shift/reduce.
2853 2001-07-11 Simon Cozens
2855 * cs-tokenizer.cs: Hex numbers should begin with a 0.
2857 Improve allow_keyword_as_indent name.
2859 2001-06-19 Miguel de Icaza <miguel@ximian.com>
2861 * Adjustments for Beta2.
2863 2001-06-13 Miguel de Icaza <miguel@ximian.com>
2865 * decl.cs: Added `Define' abstract method.
2866 (InTransit): new property, used to catch recursive definitions.
2868 * interface.cs: Implement `Define'.
2870 * modifiers.cs: Map Modifiers.constants to
2871 System.Reflection.TypeAttribute flags.
2873 * class.cs: Keep track of types and user-defined types.
2874 (BuilderInit): New method for creating an assembly
2875 (ResolveType): New function to launch the resolution process, only
2876 used by interfaces for now.
2878 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
2879 that are inserted into the name space.
2881 2001-06-08 Miguel de Icaza <miguel@ximian.com>
2883 * ARGH. I have screwed up my tree so many times due to the use of
2884 rsync rather than using CVS. Going to fix this at once.
2886 * driver.cs: Objetify driver. Load assemblies, use assemblies to
2889 2001-06-07 Miguel de Icaza <miguel@ximian.com>
2891 * Experiment successful: Use System.Type rather that our own
2894 2001-05-25 Miguel de Icaza <miguel@ximian.com>
2896 * cs-parser.jay: Removed nsAliases from here.
2898 Use new namespaces, handle `using XXX;'
2900 * namespace.cs: Reimplemented namespace handling, use a recursive
2901 definition of the class. Now we can keep track of using clauses
2902 and catch invalid using clauses.
2904 2001-05-24 Miguel de Icaza <miguel@ximian.com>
2906 * gen-treedump.cs: Adapted for all the renaming.
2908 * expression.cs (Expression): this class now has a Type property
2909 which returns an expression Type.
2911 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
2912 `Type', as this has a different meaning now in the base
2914 2001-05-22 Miguel de Icaza <miguel@ximian.com>
2916 * interface.cs, class.cs: Removed from all the sources the
2917 references to signature computation, as we can not do method
2918 signature computation during the parsing time, as we are not
2919 trying to solve at that point distinguishing:
2923 void a (NS.Blah x) {}
2926 Which depending on the context might be valid or not, as we do not
2927 know if Blah is the same thing as NS.Blah at that point.
2929 * Redid everything so the code uses TypeRefs now instead of
2930 Types. TypeRefs are just temporary type placeholders, that need
2931 to be resolved. They initially have a pointer to a string and the
2932 current scope in which they are used. This is used later by the
2933 compiler to resolve the reference to an actual Type.
2935 * DeclSpace is no longer a CIR.Type, and neither are
2936 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
2937 are all DeclSpaces, but no Types.
2939 * type.cs (TypeRefManager): This implements the TypeRef manager,
2940 which keeps track of all the types that need to be resolved after
2941 the parsing has finished.
2943 2001-05-13 Miguel de Icaza <miguel@ximian.com>
2945 * ARGH. We are going to have to store `foreach' as a class rather
2946 than resolving it, as we need to verify error 1579 after name
2947 resolution. *OR* we could keep a flag that says `This request to
2948 IEnumerator comes from a foreach statement' which we can then use
2949 to generate the error.
2951 2001-05-10 Miguel de Icaza <miguel@ximian.com>
2953 * class.cs (TypeContainer.AddMethod): we now add methods to the
2954 MethodGroup instead of the method hashtable.
2956 * expression.cs: Add MethodGroup abstraction, which gets us one
2957 step closer to the specification in the way we handle method
2960 * cs-parser.jay (primary_expression): qualified_identifier now
2961 tried to match up an identifier to a local variable reference or
2962 to a parameter reference.
2964 current_local_parameters is now a parser global variable that
2965 points to the current parameters for the block, used during name
2968 (property_declaration): Now creates an implicit `value' argument to
2971 2001-05-09 Miguel de Icaza <miguel@ximian.com>
2973 * parameter.cs: Do not use `param' arguments as part of the
2974 signature, per the spec.
2976 2001-05-08 Miguel de Icaza <miguel@ximian.com>
2978 * decl.cs: Base class for classes, structs and interfaces. This
2979 is the "Declaration Space"
2981 * cs-parser.jay: Use CheckDef for checking declaration errors
2982 instead of having one on each function.
2984 * class.cs: Factor out some code for handling error handling in
2985 accordance to the "Declarations" section in the "Basic Concepts"
2986 chapter in the ECMA C# spec.
2988 * interface.cs: Make all interface member classes derive from
2989 InterfaceMemberBase.
2991 2001-05-07 Miguel de Icaza <miguel@ximian.com>
2993 * Many things: all interfaces are parsed and generated in
2994 gen-treedump. Support for member variables, constructors,
2995 destructors, properties, constants is there.
2997 Beginning of the IL backend, but very little done, just there for
3000 2001-04-29 Miguel de Icaza <miguel@ximian.com>
3002 * cs-parser.jay: Fix labeled statement.
3004 * cs-tokenizer.cs (escape): Escape " and ' always.
3005 ref_line, ref_name: keep track of the line/filename as instructed
3006 by #line by the compiler.
3009 2001-04-27 Miguel de Icaza <miguel@ximian.com>
3011 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
3012 to match the values in System.CodeDOM.
3014 Divid renamed to Divide.
3016 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
3018 (Statements.set): remove.
3020 * System.CodeDOM/CodeCatchClause.cs: always have a valid
3023 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
3024 falseStatements always have valid values.
3026 * cs-parser.jay: Use System.CodeDOM now.
