3 * class.cs (TypeContainer::RegisterRequiredImplementations):
4 Record methods we need.
6 (TypeContainer::MakeKey): Helper function to make keys for
7 MethodBases, since the Methodbase key is useless.
9 (TypeContainer::Populate): Call RegisterRequiredImplementations
10 before defining the methods.
12 Create a mapping for method_builders_to_methods ahead of time
13 instead of inside a tight loop.
15 (::RequireMethods): Accept an object as the data to set into the
16 hashtable so we can report interface vs abstract method mismatch.
18 2001-10-03 Miguel de Icaza <miguel@ximian.com>
20 * report.cs: Make all of it static.
22 * rootcontext.cs: Drop object_type and value_type computations, as
23 we have those in the TypeManager anyways.
25 Drop report instance variable too, now it is a global.
27 * driver.cs: Use try/catch on command line handling.
29 Add --probe option to debug the error reporting system with a test
32 * report.cs: Add support for exiting program when a probe
35 2001-10-03 Ravi Pratap <ravi@ximian.com>
37 * expression.cs (Binary::DoNumericPromotions): Fix the case when

43 (Unary::error23): Use location here too.
45 * ../errors/cs0019.cs : Check in.
47 * ../errors/cs0023.cs : Check in.
49 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
50 case of a non-null MethodInfo object with a length of 0 !
52 (Binary::ResolveOperator): Flag error if overload resolution fails to find
53 an applicable member - according to the spec :-)
54 Also fix logic to find members in base types.
56 (Unary::ResolveOperator): Same here.
58 (Unary::report23): Change name to error23 and make first argument a TypeContainer
59 as I was getting thoroughly confused between this and error19 :-)
61 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
62 (::FindMostEncompassedType): Implement.
63 (::FindMostEncompassingType): Implement.
64 (::StandardConversionExists): Implement.
66 (UserImplicitCast): Re-vamp. We now need info about most specific
67 source and target types so that we can do the necessary conversions.
69 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
70 mathematical union with no duplicates.
72 2001-10-03 Miguel de Icaza <miguel@ximian.com>
74 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
75 in order from base classes to child classes, so that we can in
76 child classes look up in our parent for method names and
77 attributes (required for handling abstract, virtual, new, override
78 constructs: we need to instrospect our base class, and if we dont
79 populate the classes in order, the introspection might be
80 incorrect. For example, a method could query its parent before
81 the parent has any methods and would determine that the parent has
82 no abstract methods (while it could have had them)).
84 (RootContext::CreateType): Record the order in which we define the
87 2001-10-02 Miguel de Icaza <miguel@ximian.com>

97 (Method::Emit) Return the MethodBuilder.
98 Check for abstract or virtual methods to be public.
100 * rootcontext.cs (RootContext::CreateType): Register all the
101 abstract methods required for the class to be complete and the
102 interface methods that must be implemented.
104 * cs-parser.jay: Report error 501 (method requires body if it is
105 not marked abstract or extern).
107 * expression.cs (TypeOf::Emit): Implement.
109 * typemanager.cs: runtime_handle_type, new global type.
111 * class.cs (Property::Emit): Generate code for properties.
113 2001-10-02 Ravi Pratap <ravi@ximian.com>
115 * expression.cs (Unary::ResolveOperator): Find operators on base type
116 too - we now conform exactly to the spec.
118 (Binary::ResolveOperator): Same here.
120 * class.cs (Operator::Define): Fix minor quirk in the tests.
122 * ../errors/cs0215.cs : Added.
124 * ../errors/cs0556.cs : Added.
126 * ../errors/cs0555.cs : Added.
128 2001-10-01 Miguel de Icaza <miguel@ximian.com>
130 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
131 single integer which is really efficient
133 2001-10-01 Ravi Pratap <ravi@ximian.com>
135 * expression.cs (Expression::ImplicitUserConversion): Use location
136 even in the case when we are examining True operators.
138 * class.cs (Operator::Define): Perform extensive checks to conform
139 with the rules for operator overloading in the spec.
141 * expression.cs (Expression::ImplicitReferenceConversion): Implement
142 some of the other conversions mentioned in the spec.
144 * typemanager.cs (array_type): New static member for the System.Array built-in
147 (cloneable_interface): For System.ICloneable interface.
149 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
150 we start resolving the tree and populating types.
152 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
154 2001-10-01 Miguel de Icaza <miguel@ximian.com>
156 * expression.cs (Expression::ExprClassFromMemberInfo,
157 Expression::Literalize): Create literal expressions from
158 FieldInfos which are literals.
160 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
161 type casts, because they were wrong. The test suite in tests
164 (ImplicitNumericConversion): ushort to ulong requires a widening
167 Int32 constant to long requires widening cast as well.
169 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
170 for integers because the type on the stack is not i4.
172 2001-09-30 Miguel de Icaza <miguel@ximian.com>
174 * expression.cs (report118): require location argument.
176 * parameter.cs: Do not dereference potential null value.
178 * class.cs: Catch methods that lack the `new' keyword when
179 overriding a name. Report warnings when `new' is used without
180 anything being there to override.
182 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
184 * class.cs: Only add constructor to hashtable if it is non-null
185 (as now constructors can fail on define).
187 (TypeManager, Class, Struct): Take location arguments.
189 Catch field instance initialization in structs as errors.
191 accepting_filter: a new filter for FindMembers that is static so
192 that we dont create an instance per invocation.
194 (Constructor::Define): Catch errors where a struct constructor is
197 * cs-parser.jay: Pass location information for various new
200 * delegate.cs (Delegate): take a location argument.
202 * driver.cs: Do not call EmitCode if there were problesm in the
203 Definition of the types, as many Builders wont be there.
205 * decl.cs (Decl::Decl): Require a location argument.
207 * cs-tokenizer.cs: Handle properly hex constants that can not fit
208 into integers, and find the most appropiate integer for it.
210 * literal.cs: Implement ULongLiteral.
212 * rootcontext.cs: Provide better information about the location of
213 failure when CreateType fails.
215 2001-09-29 Miguel de Icaza <miguel@ximian.com>
217 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
220 * expression.cs (Binary::CheckShiftArguments): Add missing type
222 (Binary::ResolveOperator): Add type to the logical and and logical
223 or, Bitwise And/Or and Exclusive Or code paths, it was missing
226 (Binary::DoNumericPromotions): In the case where either argument
227 is ulong (and most signed types combined with ulong cause an
228 error) perform implicit integer constant conversions as well.
230 2001-09-28 Miguel de Icaza <miguel@ximian.com>
232 * expression.cs (UserImplicitCast): Method should always be
234 (Invocation::BetterConversion): Simplified test for IntLiteral.
236 (Expression::ImplicitNumericConversion): Split this routine out.
237 Put the code that performs implicit constant integer conversions
240 (Expression::Resolve): Become a wrapper around DoResolve so we can
241 check eclass and type being set after resolve.
243 (Invocation::Badness): Remove this dead function
245 (Binary::ResolveOperator): Do not compute the expensive argumnets
246 unless we have a union for it.
248 (Probe::Emit): Is needs to do an isinst and then
249 compare against null.
251 (::CanConvert): Added Location argument. If the Location argument
252 is null (Location.Null), then we do not report errors. This is
253 used by the `probe' mechanism of the Explicit conversion. We do
254 not want to generate an error for something that the user
255 explicitly requested to be casted. But the pipeline for an
256 explicit cast first tests for potential implicit casts.
258 So for now, if the Location is null, it means `Probe only' to
259 avoid adding another argument. Might have to revise this
262 (ClassCast): New class used to type cast objects into arbitrary
263 classes (used in Explicit Reference Conversions).
265 Implement `as' as well.
267 Reverted all the patches from Ravi below: they were broken:
269 * The use of `level' as a mechanism to stop recursive
270 invocations is wrong. That was there just to catch the
271 bug with a strack trace but not as a way of addressing
274 To fix the problem we have to *understand* what is going
275 on and the interactions and come up with a plan, not
276 just get things going.
278 * The use of the type conversion cache that I proposed
279 last night had an open topic: How does this work across
280 protection domains. A user defined conversion might not
281 be public in the location where we are applying the
282 conversion, a different conversion might be selected
283 (ie, private A->B (better) but public B->A (worse),
284 inside A, A->B applies, but outside it, B->A will
287 * On top of that (ie, even if the above is solved),
288 conversions in a cache need to be abstract. Ie, `To
289 convert from an Int to a Short use an OpcodeCast', not
290 `To convert from an Int to a Short use the OpcodeCast on
291 the variable 5' (which is what this patch was doing).
293 2001-09-28 Ravi Pratap <ravi@ximian.com>
295 * expression.cs (Invocation::ConversionExists): Re-write to use
298 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
299 cache all conversions done, not just user-defined ones.
301 (Invocation::BetterConversion): The real culprit. Use ConversionExists
302 to determine if a conversion exists instead of acutually trying to
303 perform the conversion. It's faster too.
305 (Expression::ConvertExplicit): Modify to use ConversionExists to check
306 and only then attempt the implicit conversion.
308 2001-09-28 Ravi Pratap <ravi@ximian.com>
310 * expression.cs (ConvertImplicit): Use a cache for conversions
311 already found. Check level of recursion and bail out if necessary.
313 2001-09-28 Miguel de Icaza <miguel@ximian.com>
315 * typemanager.cs (string_concat_string_string, string_concat_object_object):
316 Export standard methods that we expect for string operations.
318 * statement.cs (Block::UsageWarning): Track usage of variables and
319 report the errors for not used variables.
321 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
324 2001-09-27 Miguel de Icaza <miguel@ximian.com>
326 * codegen.cs: remove unnneded code
328 * expression.cs: Removed BuiltinTypeAccess class
330 Fix the order in which implicit conversions are
333 The previous fixed dropped support for boxed conversions (adding a
334 test to the test suite now)
336 (UserImplicitCast::CanConvert): Remove test for source being null,
337 that code is broken. We should not feed a null to begin with, if
338 we do, then we should track the bug where the problem originates
339 and not try to cover it up here.
341 Return a resolved expression of type UserImplicitCast on success
342 rather than true/false. Ravi: this is what I was talking about,
343 the pattern is to use a static method as a "constructor" for
346 Also, do not create arguments until the very last minute,
347 otherwise we always create the arguments even for lookups that
348 will never be performed.
350 (UserImplicitCast::Resolve): Eliminate, objects of type
351 UserImplicitCast are born in a fully resolved state.
353 * typemanager.cs (InitCoreTypes): Init also value_type
356 * expression.cs (Cast::Resolve): First resolve the child expression.
358 (LValue): Add new method AddressOf to be used by
361 Change the argument of Store to take an EmitContext instead of an
362 ILGenerator, because things like FieldExpr need to be able to call
363 their children expression to generate the instance code.
365 (Expression::Error, Expression::Warning): Sugar functions for
368 (Expression::MemberLookup): Accept a TypeContainer instead of a
369 Report as the first argument.
371 (Expression::ResolvePrimary): Killed. I still want to improve
372 this as currently the code is just not right.
374 (Expression::ResolveMemberAccess): Simplify, but it is still
377 (Unary::Resolve): Catch errors in AddressOf operators.
379 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
380 index to a byte for the short-version, or the compiler will choose
381 the wrong Emit call, which generates the wrong data.
383 (ParameterReference::Emit, ::Store): same.
385 (FieldExpr::AddressOf): Implement.
387 * typemanager.cs: TypeManager: made public variable instead of
390 * driver.cs: document --fatal.
392 * report.cs (ErrorMessage, WarningMessage): new names for the old
393 Error and Warning classes.
395 * cs-parser.jay (member_access): Turn built-in access to types
396 into a normal simplename
398 2001-09-27 Ravi Pratap <ravi@ximian.com>
400 * expression.cs (Invocation::BetterConversion): Fix to cope
401 with q being null, since this was introducing a bug.

411 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
412 I had introduced long ago (what's new ?).
414 * expression.cs (UserImplicitCast::CanConvert): Static method to do
415 the work of all the checking.
416 (ConvertImplicit): Call CanConvert and only then create object if necessary.
417 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
419 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
420 that is the right way.
422 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
423 overloading resolution. Use everywhere instead of cutting and pasting code.
425 (Binary::ResolveOperator): Use MakeUnionSet.
427 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
428 we have to convert to bool types. Not complete yet.
430 2001-09-27 Miguel de Icaza <miguel@ximian.com>
432 * typemanager.cs (TypeManager::CSharpName): support ushort.
434 * expression.cs (Expression::TryImplicitIntConversion): Attempts
435 to provide an expression that performsn an implicit constant int
436 conversion (section 6.1.6).
437 (Expression::ConvertImplicitRequired): Reworked to include
438 implicit constant expression conversions.
440 (Expression::ConvertNumericExplicit): Finished.
442 (Invocation::Emit): If InstanceExpression is null, then it means
443 that we perform a call on this.
445 2001-09-26 Miguel de Icaza <miguel@ximian.com>
447 * expression.cs (Unary::Emit): Remove some dead code.
448 (Probe): Implement Resolve and Emit for `is'.
449 (Expression::ConvertImplicitRequired): Attempt to do constant
450 expression conversions here. Maybe should be moved to
451 ConvertImplicit, but I am not sure.
452 (Expression::ImplicitLongConstantConversionPossible,
453 Expression::ImplicitIntConstantConversionPossible): New functions
454 that tell whether is it possible to apply an implicit constant
455 expression conversion.
457 (ConvertNumericExplicit): Started work on explicit numeric
460 * cs-parser.jay: Update operator constants.
462 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
463 (Parameters::GetSignature): Hook up VerifyArgs here.
464 (Parameters::VerifyArgs): Verifies that no two arguments have the
467 * class.cs (Operator): Update the operator names to reflect the
468 ones that the spec expects (as we are just stringizing the
471 * expression.cs (Unary::ResolveOperator): Fix bug: Use
472 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
473 previous usage did only work for our methods.
474 (Expression::ConvertImplicit): Handle decimal implicit numeric
476 (Expression::InternalTypeConstructor): Used to invoke constructors
477 on internal types for default promotions.
479 (Unary::Emit): Implement special handling for the pre/post
480 increment/decrement for overloaded operators, as they need to have
481 the same semantics as the other operators.
483 (Binary::ResolveOperator): ditto.
484 (Invocation::ConversionExists): ditto.
485 (UserImplicitCast::Resolve): ditto.
487 2001-09-26 Ravi Pratap <ravi@ximian.com>

501 * assign.cs (Assign): Make it inherit from ExpressionStatement.
503 * expression.cs (ExpressionStatement): New base class used for
504 expressions that can appear in statements, so that we can provide
505 an alternate path to generate expression that do not leave a value
508 (Expression::Emit, and all the derivatives): We no longer return
509 whether a value is left on the stack or not. Every expression
510 after being emitted leaves a single value on the stack.
512 * codegen.cs (EmitContext::EmitStatementExpression): Use the
513 facilties of ExpressionStatement if possible.
515 * cs-parser.jay: Update statement_expression.

528 * expression.cs (Invocation::ConversionExists): Correct the member lookup
529 to find "op_Implicit", not "implicit" ;-)

540 * assign.cs: track location.
541 (Resolve): Use implicit conversions on assignment.
543 * literal.cs: Oops. Not good, Emit of short access values should
544 pass (Bytes) or the wrong argument will be selected.
546 * expression.cs (Unary::Emit): Emit code for -expr.
548 (Unary::ResolveOperator): Handle `Substract' for non-constants
549 (substract from zero from the non-constants).

553 error if no implicit conversion exists.
555 (Invocation::OverloadResolve): Store the converted implicit
556 expressions if we make them

585 Also take an additional TypeContainer argument.
587 * All over : Pass in TypeContainer as argument to OverloadResolve.
589 * typemanager.cs (CSharpName): Update to check for the string type and return
592 * expression.cs (Invocation::FullMethodDesc): New static method to return a string fully describing

606 * typemanager.cs: declare and load enum_type, delegate_type and
609 * expression.cs (Expression::Emit): Now emit returns a value that
610 tells whether a value is left on the stack or not. This strategy
611 might be reveted tomorrow with a mechanism that would address
612 multiple assignments.
613 (Expression::report118): Utility routine to report mismatches on
616 (Unary::Report23): Report impossible type/operator combination
619 (Unary::IsIncrementableNumber): Whether the type can be
620 incremented or decremented with add.
621 (Unary::ResolveOperator): Also allow enumerations to be bitwise
623 (Unary::ResolveOperator): Implement ++, !, ~, ++ and --.
625 (Invocation::Emit): Deal with new Emit convetion.
627 * All Expression derivatives: Updated their Emit method to return
628 whether they leave values on the stack or not.
630 * codegen.cs (CodeGen::EmitStatement): Pop values left on the
631 stack for expressions that are statements.
633 2001-09-20 Miguel de Icaza <miguel@ximian.com>
635 * expression.cs (LValue): New interface. Must be implemented by
637 (LocalVariableReference, ParameterReference, FieldExpr): Implement
640 * assign.cs (Assign::Emit, Assign::Resolve): Use new LValue
641 interface for generating code, simplifies the code.

656 * cs-parser.jay (QualifierIdentifier): Pass location to SimpleName
659 * statement.cs (Block::EmitMeta): Reuse the count across all the variables,
660 otherwise nested blocks end up with the same index.
662 * codegen.cs (CodeGen::EmitTopBlock): Pass initial sequence
664 * expression.cs: Instead of having FIXMEs in the Resolve
665 functions, throw exceptions so it is obvious that we are facing a
668 * cs-parser.jay (invocation_expression): Pass Location information.
670 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
671 Use a basename for those routines because .NET does not like paths

683 * expression.cs (Unary::ResolveOperator): return the child
684 expression for expressions which are just +expr.
685 (Unary::ResolveOperator): Return negative literals for -LITERAL
686 expressions (otherwise they are Unary {Literal}).

688 expression conversions'.

709 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
710 operators are found instead of making noise ;-)
711 (Unary::ResolveOperator): New method to do precisely the same thing which
712 Binary::ResolveOperator does for Binary expressions.
713 (Unary.method, .Arguments): Add.

741 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
742 the last instruction contains a return opcode to avoid generating
743 the last `ret' instruction (this generates correct code, and it is
744 nice to pass the peverify output).
746 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
747 initializer for static and instance variables.
748 (Constructor::Emit): Allow initializer to be null in the case of
749 static constructors. Only emit initializer for instance
752 (TypeContainer::FindMembers): Return a null array if there are no

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

802 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
805 (Expression::MemberLookup): Provide a version that allows to
806 specify the MemberTypes and BindingFlags.

823 constructors as we now "emit" them at a higher level.
825 (TypeContainer::DefineDefaultConstructor): Used to define the
826 default constructors if none was provided.

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

915 have to cope with the

919 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

924 * driver.cs: Added --parse option that only parses its input files
927 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
928 incorrect. IsTopLevel is not used to tell whether an object is
929 root_types or not (that can be achieved by testing this ==
930 root_types). But to see if this is a top-level *class* (not
931 necessarly our "toplevel" container).
933 2001-09-14 Ravi Pratap <ravi@ximian.com>
935 * enum.cs (Enum::Define): Modify to call the Lookup method on the

938 2001-09-14 Ravi Pratap <ravi@ximian.com>
940 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
941 Modifiers.TypeAttr. This should just be a call to that method.
943 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
944 object so that we can determine if we are top-level or not.
946 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the

957 * modifiers.cs (MethodAttr): Re-write.
958 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
960 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
961 of top-level types as claimed.
963 2001-09-13 Miguel de Icaza <miguel@ximian.com>
965 * expression.cs (MemberLookup): Fruitless attempt to lookup
966 constructors. Maybe I need to emit default constructors? That
967 might be it (currently .NET emits this for me automatically).
968 (Invocation::OverloadResolve): Cope with Arguments == null.
969 (Invocation::EmitArguments): new function, shared by the new

995 * expression.cs (PropertyExpr): Initialize type from the
998 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

1003 (Binary::ResolveOperator): Set the return type to boolean for
1004 comparission operators
1006 * typemanager.cs: Remove debugging print code.
1008 (Invocation::Resolve): resolve type.
1010 * class.cs: Allocate a MemberInfo of the correct size, as the code
1011 elsewhere depends on the test to reflect the correct contents.
1013 (Method::) Keep track of parameters, due to System.Reflection holes
1015 (TypeContainer::Populate): Keep track of MethodBuilders to Method
1018 (TypeContainer::FindMembers): Use ArrayList and then copy an array
1019 of the exact size and return that.
1021 (Class::LookupMethodByBuilder): New function that maps
1022 MethodBuilders to its methods. Required to locate the information
1023 on methods because System.Reflection bit us again.
1025 * support.cs: New file, contains an interface ParameterData and
1026 two implementations: ReflectionParameters and InternalParameters
1027 used to access Parameter information. We will need to grow this
1030 * expression.cs (Invocation::GetParameterData): implement a cache
1031 and a wrapper around the ParameterData creation for methods.
1032 (Invocation::OverloadResolve): Use new code.
1034 2001-09-13 Ravi Pratap <ravi@ximian.com>

1095 typecontainer objects as we need to get at them.
1096 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

1138 addOn_ and removeOn_
1140 * genericparser.cs (GenericParser::error): Overloaded method to handle the case

1191 already might have something already fully qualified like
1192 'System.Console.WriteLine'

1343 will is used during the tree rewriting as we resolve them during

1445 used anywhere - non-reducing rule.
1446 (namespace_declarations): Non-reducing rule - comment out.
1448 * enum.cs (Enum::AddEnum): Rename to AddEnumMember as I was getting confused
1449 with TypeContainer::AddEnum.

1461 (Event.EventBuilder): New member.
1463 * class.cs (TypeContainer::Populate): Update to define all enums and events
1465 (Events): New property for the events arraylist we hold. Shouldn't we move to using

1468 2001-08-31 Ravi Pratap <ravi@che.iitm.ac.in>
1470 * class.cs (Property): Revamp to use the convention of making fields readonly.
1471 Accordingly modify code elsewhere.

1516 (catch_clauses): Modify accordingly.
1517 (opt_catch_clauses): New production to use in try_statement
1518 (try_statement): Revamp. Basically, we get rid of one unnecessary rule
1519 and re-write the code in the actions to extract the specific and
1520 general catch clauses by being a little smart ;-)
1522 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
1523 Hooray, try and catch statements parse fine !
1525 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1527 * statement.cs (Block::GetVariableType): Fix logic to extract the type
1528 string from the hashtable of variables.
1530 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did
1531 I end up making that mistake ;-)
1532 (catch_clauses): Fixed gross error which made Key and Value of the
1533 DictionaryEntry the same : $1 !!
1535 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
1537 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
1539 * cs-parser.jay (event_declaration): Correct to remove the semicolon
1540 when the add and remove accessors are specified.

1545 information about indexer_declarator.
1546 (indexer_declarator): Implement actions.
1547 (parsing_indexer): New local boolean used to keep track of whether

1575 concatenating all the commas together, just as they appear.
1576 (opt_dim_separators): Modify accordingly
1577 (rank_specifiers): Update accordingly. Basically do the same
1578 thing - instead, collect the brackets here.
1579 (opt_rank_sepcifiers): Modify accordingly.

1581 instead of ignoring the rank_specifiers.
1582 (expression_list): Implement to collect the expressions

1604 constructors instead of returning null.
1606 2001-08-26 Miguel de Icaza <miguel@ximian.com>
1608 * typemanager.cs (InitCoreTypes): Initialize the various core
1609 types after we have populated the type manager with the user
1610 defined types (this distinction will be important later while
1611 compiling corlib.dll)
1613 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
1614 on Expression Classification. Now all expressions have a method
1615 `Resolve' and a method `Emit'.
1617 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
1618 generation from working. Also add some temporary debugging
1621 2001-08-24 Miguel de Icaza <miguel@ximian.com>
1623 * codegen.cs: Lots of code generation pieces. This is only the
1624 beginning, will continue tomorrow with more touches of polish. We
1625 handle the fundamentals of if, while, do, for, return. Others are
1626 trickier and I need to start working on invocations soon.
1628 * gen-treedump.cs: Bug fix, use s.Increment here instead of
1631 * codegen.cs (EmitContext): New struct, used during code
1632 emission to keep a context. Most of the code generation will be
1635 * cs-parser.jay: Add embedded blocks to the list of statements of
1636 this block. So code generation proceeds in a top down fashion.
1638 2001-08-23 Miguel de Icaza <miguel@ximian.com>

1652 * class.cs: Drop support for MethodGroups here, delay until
1654 (Method::): Applied the same simplification that I did before, and
1655 move from Properties to public readonly fields.
1656 (Method::ParameterTypes): Returns the parameter types for the
1657 function, and implements a cache that will be useful later when I
1658 do error checking and the semantic analysis on the methods is
1660 (Constructor::GetCallingConvention): Renamed from CallingConvetion
1661 and made a method, optional argument tells whether this is a class
1662 or a structure to apply the `has-this' bit.
1663 (Method::GetCallingConvention): Implement, returns the calling
1665 (Method::Define): Defines the type, a second pass is performed
1666 later to populate the methods.

1687 (TypeContainer::AddConstructor): Keep track of default constructor
1688 and the default static constructor.
1690 (Constructor::) Another class that starts using `public readonly'
1691 instead of properties.
1693 (Constructor::IsDefault): Whether this is a default constructor.
1695 (Field::) use readonly public fields instead of properties also.
1697 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
1698 track of static constructors; If none is used, turn on
1699 BeforeFieldInit in the TypeAttributes.
1701 * cs-parser.jay (opt_argument_list): now the return can be null
1702 for the cases where there are no arguments.
1704 (constructor_declarator): If there is no implicit `base' or
1705 `this', then invoke the default parent constructor.
1707 * modifiers.cs (MethodAttr): New static function maps a set of
1708 modifiers flags into a MethodAttributes enum
1709 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
1710 MethodAttr, TypeAttr to represent the various mappings where the
1712 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
1714 2001-08-19 Miguel de Icaza <miguel@ximian.com>

1720 for interface indexers.
1722 2001-08-17 Miguel de Icaza <miguel@ximian.com>
1724 * interface.cs (InterfaceMemberBase): Now we track the new status
1727 (PopulateProperty): Implement property population. Woohoo! Got
1728 Methods and Properties going today.
1730 Removed all the properties for interfaces, and replaced them with
1731 `public readonly' fields.
1733 2001-08-16 Miguel de Icaza <miguel@ximian.com>
1735 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
1736 initialize their hashtables/arraylists only when they are needed
1737 instead of doing this always.
1739 * parameter.cs: Handle refs and out parameters.
1741 * cs-parser.jay: Use an ArrayList to construct the arguments
1742 instead of the ParameterCollection, and then cast that to a
1745 * parameter.cs: Drop the use of ParameterCollection and use
1746 instead arrays of Parameters.
1748 (GetParameterInfo): Use the Type, not the Name when resolving
1751 2001-08-13 Miguel de Icaza <miguel@ximian.com>
1753 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
1754 and instead use public readonly fields.

1760 * class.cs (MakeConstant): Code to define constants.
1762 * rootcontext.cs (LookupType): New function. Used to locate types
1765 2001-08-08 Miguel de Icaza <miguel@ximian.com>
1767 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
1768 this System.Reflection code is. Kudos to Microsoft
1770 * typemanager.cs: Implement a type cache and avoid loading all
1771 types at boot time. Wrap in LookupType the internals. This made
1772 the compiler so much faster. Wow. I rule!
1774 * driver.cs: Make sure we always load mscorlib first (for
1775 debugging purposes, nothing really important).
1777 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
1778 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
1780 * rootcontext.cs: Lookup types on their namespace; Lookup types
1781 on namespaces that have been imported using the `using' keyword.
1783 * class.cs (TypeContainer::TypeAttr): Virtualize.
1784 (Class::TypeAttr): Return attributes suitable for this bad boy.
1785 (Struct::TypeAttr): ditto.
1786 Handle nested classes.
1787 (TypeContainer::) Remove all the type visiting code, it is now
1788 replaced with the rootcontext.cs code

1798 2001-08-04 Miguel de Icaza <miguel@ximian.com>
1802 * class.cs (Struct::Struct): set the SEALED flags after
1803 checking the modifiers.
1804 (TypeContainer::TypeAttr): new property, returns the
1805 TypeAttributes for a class.
1807 * cs-parser.jay (type_list): Oops, list production was creating a
1808 new list of base types.
1810 * rootcontext.cs (StdLib): New property.
1811 (GetInterfaceTypeByName): returns an interface by type name, and
1812 encapsulates error handling here.
1813 (GetInterfaces): simplified.
1814 (ResolveTree): Encapsulated all the tree resolution here.
1815 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
1818 * driver.cs: Add support for --nostdlib, to avoid loading the
1820 (Main): Do not put tree resolution here.
1822 * rootcontext.cs: Beginning of the class resolution.
1824 2001-08-03 Miguel de Icaza <miguel@ximian.com>
1826 * rootcontext.cs: Provide better error reporting.
1828 * cs-parser.jay (interface_base): set our $$ to be interfaces.

1839 the type on the global type hash, and allows us to close it at the
1842 2001-08-02 Miguel de Icaza <miguel@ximian.com>
1844 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
1845 RecordInterface instead.
1847 * cs-parser.jay: Updated to reflect changes above.
1849 * decl.cs (Definition): Keep track of the TypeBuilder type that
1850 represents this type here. Not sure we will use it in the long
1851 run, but wont hurt for now.
1853 * driver.cs: Smaller changes to accomodate the new code.
1855 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly

1866 * cs-parser.jay: Add a second production for delegate_declaration
1869 (enum_body): Put an opt_comma here instead of putting it on
1870 enum_body or enum_member_declarations so we can handle trailing
1871 commas on enumeration members. Gets rid of a shift/reduce.
1873 (type_list): Need a COMMA in the middle.
1875 (indexer_declaration): Tell tokenizer to recognize get/set
1877 * Remove old targets.

1894 representation and the defined types available to the program.
1896 * gen-treedump.cs: adjust for new convention.
1898 * type.cs: Split out the type manager, and the assembly builder

1929 * decl.cs: Added `Define' abstract method.
1930 (InTransit): new property, used to catch recursive definitions.
1932 * interface.cs: Implement `Define'.
1934 * modifiers.cs: Map Modifiers.constants to
1935 System.Reflection.TypeAttribute flags.
1937 * class.cs: Keep track of types and user-defined types.
1938 (BuilderInit): New method for creating an assembly
1939 (ResolveType): New function to launch the resolution process, only
1940 used by interfaces for now.
1942 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
1943 that are inserted into the name space.
1945 2001-06-08 Miguel de Icaza <miguel@ximian.com>
1947 * ARGH. I have screwed up my tree so many times due to the use of
1948 rsync rather than using CVS. Going to fix this at once.
1950 * driver.cs: Objetify driver. Load assemblies, use assemblies to
1953 2001-06-07 Miguel de Icaza <miguel@ximian.com>
1955 * Experiment successful: Use System.Type rather that our own
1958 2001-05-25 Miguel de Icaza <miguel@ximian.com>
1960 * cs-parser.jay: Removed nsAliases from here.
1962 Use new namespaces, handle `using XXX;'
1964 * namespace.cs: Reimplemented namespace handling, use a recursive
1965 definition of the class. Now we can keep track of using clauses
1966 and catch invalid using clauses.
1968 2001-05-24 Miguel de Icaza <miguel@ximian.com>
1970 * gen-treedump.cs: Adapted for all the renaming.
1972 * expression.cs (Expression): this class now has a Type property
1973 which returns an expression Type.
1975 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
1976 `Type', as this has a different meaning now in the base
1978 2001-05-22 Miguel de Icaza <miguel@ximian.com>
1980 * interface.cs, class.cs: Removed from all the sources the
1981 references to signature computation, as we can not do method
1982 signature computation during the parsing time, as we are not
1983 trying to solve at that point distinguishing:
1987 void a (NS.Blah x) {}
1990 Which depending on the context might be valid or not, as we do not
1991 know if Blah is the same thing as NS.Blah at that point.
1993 * Redid everything so the code uses TypeRefs now instead of
1994 Types. TypeRefs are just temporary type placeholders, that need
1995 to be resolved. They initially have a pointer to a string and the
1996 current scope in which they are used. This is used later by the
1997 compiler to resolve the reference to an actual Type.
1999 * DeclSpace is no longer a CIR.Type, and neither are
2000 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
2001 are all DeclSpaces, but no Types.
2003 * type.cs (TypeRefManager): This implements the TypeRef manager,
2004 which keeps track of all the types that need to be resolved after
2005 the parsing has finished.
2007 2001-05-13 Miguel de Icaza <miguel@ximian.com>
2009 * ARGH. We are going to have to store `foreach' as a class rather
2010 than resolving it, as we need to verify error 1579 after name
2011 resolution. *OR* we could keep a flag that says `This request to
2012 IEnumerator comes from a foreach statement' which we can then use
2013 to generate the error.
2015 2001-05-10 Miguel de Icaza <miguel@ximian.com>
2017 * class.cs (TypeContainer.AddMethod): we now add methods to the
2018 MethodGroup instead of the method hashtable.
2020 * expression.cs: Add MethodGroup abstraction, which gets us one
2021 step closer to the specification in the way we handle method
2024 * cs-parser.jay (primary_expression): qualified_identifier now
2025 tried to match up an identifier to a local variable reference or
2026 to a parameter reference.
2028 current_local_parameters is now a parser global variable that
2029 points to the current parameters for the block, used during name
2032 (property_declaration): Now creates an implicit `value' argument to
2035 2001-05-09 Miguel de Icaza <miguel@ximian.com>
2037 * parameter.cs: Do not use `param' arguments as part of the
2038 signature, per the spec.
2040 2001-05-08 Miguel de Icaza <miguel@ximian.com>
2042 * decl.cs: Base class for classes, structs and interfaces. This
2043 is the "Declaration Space"
2045 * cs-parser.jay: Use CheckDef for checking declaration errors
2046 instead of having one on each function.
2048 * class.cs: Factor out some code for handling error handling in
2049 accordance to the "Declarations" section in the "Basic Concepts"
2050 chapter in the ECMA C# spec.
2052 * interface.cs: Make all interface member classes derive from
2053 InterfaceMemberBase.
2055 2001-05-07 Miguel de Icaza <miguel@ximian.com>
2057 * Many things: all interfaces are parsed and generated in
2058 gen-treedump. Support for member variables, constructors,
2059 destructors, properties, constants is there.
2061 Beginning of the IL backend, but very little done, just there for
2064 2001-04-29 Miguel de Icaza <miguel@ximian.com>
2066 * cs-parser.jay: Fix labeled statement.
2068 * cs-tokenizer.cs (escape): Escape " and ' always.
2069 ref_line, ref_name: keep track of the line/filename as instructed
2070 by #line by the compiler.
2073 2001-04-27 Miguel de Icaza <miguel@ximian.com>
2075 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
2076 to match the values in System.CodeDOM.
2078 Divid renamed to Divide.
2080 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
2082 (Statements.set): remove.
2084 * System.CodeDOM/CodeCatchClause.cs: always have a valid
2087 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
2088 falseStatements always have valid values.
2090 * cs-parser.jay: Use System.CodeDOM now.
