3 * expression.cs (Binary.ResolveOperator): In the object + string
4 case, I was missing a call to ConvertImplicit
6 2002-02-25 Ravi Pratap <ravi@ximian.com>
8 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
9 Location arguments. Ensure we use RootContext.LookupType to do our work
10 and not try to do a direct Type.GetType and ModuleBuilder.GetType
12 * interface.cs (PopulateMethod): Handle the type of the parameter being
15 * expression.cs (Invocation.BetterFunction): Handle the case when we
16 have a params method with no fixed arguments and a call is made with no

26 (InternalParameters.ParameterType): ditto.
28 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
29 duplicating the name of the variable parameter.
30 (GetParameterByName): Fix bug where we were not looking up array
31 paramters if they were the only present (thanks Paolo!).
32 (GetParameterInfo): We only have an empty set of types if both
33 fixed and array are set to null.
34 (GetParameterInfo-idx): Handle FixedParameter == null
36 * cs-parser.jay: Handle the case where there is no catch
37 statements (missing null test).
39 2002-02-22 Miguel de Icaza <miguel@ximian.com>
41 * driver.cs (MainDriver): Be conservative on our command line
44 Catch DirectoryNotFoundException when calling GetFiles.
46 (SplitPathAndPattern): Used to split the input specification into
47 a path and a pattern that we can feed to Directory.GetFiles.
49 2002-02-21 Miguel de Icaza <miguel@ximian.com>
51 * statement.cs (Fixed): Implement the last case of the Fixed
52 statement (string handling).
54 * expression.cs (StringPtr): New class used to return a char * to
55 a string; Used by the Fixed statement.
57 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
59 * expression.cs (Binary.ResolveOperator): Remove redundant
60 MemberLookup pn parent type.
61 Optimize union call, we do not need a union if the types are the same.
62 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
65 Specialize the use of MemberLookup everywhere, instead of using
68 (StackAlloc): Implement stackalloc keyword.
70 * cs-parser.jay: Add rule to parse stackalloc.

84 Handle pointer comparission.
85 (ArrayPtr): Utility expression class that is used to take the
88 (ElementAccess): Implement array access for pointers
90 * statement.cs (Fixed): Implement fixed statement for arrays, we
91 are missing one more case before we are done.
93 * expression.cs (Indirection): Implement EmitAssign and set the
94 ExprClass to Variable. This allows pointer dereferences to be
95 treated as variables, and to have values assigned to them.
97 * ecore.cs (Expression.StoreFromPtr): New utility function to
98 store values dereferencing.
100 2002-02-20 Ravi Pratap <ravi@ximian.com>
102 * expression.cs (Binary.ResolveOperator): Ensure that we are
103 not trying to operate on a void type - this fixes the reported
106 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
107 the parent implementation is sealed.

111 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
113 * typemanager.cs (unverifiable_code_type): Corresponds to
114 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
115 which have unsafe code in them.
117 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
120 2002-02-19 Miguel de Icaza <miguel@ximian.com>
122 * cs-tokenizer.cs: Add support for @"litreal strings"
124 Make tokenizer accept pre-processor directives
125 on any column (remove the old C-like limitation).

145 statement for the &x case.
147 2002-02-14 Miguel de Icaza <miguel@ximian.com>
149 * class.cs (Property.Define, Method.Define): Remove newslot when
152 * modifiers.cs: My use of NewSlot when `Abstract' was set was
153 wrong. NewSlot should only be used if the `new' keyword is present.
155 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
156 locating our system dir. Sorry about this.
158 2002-02-13 Miguel de Icaza <miguel@ximian.com>
160 * driver.cs (GetSystemDir): Compute correctly the location of our
161 system assemblies. I was using the compiler directory instead of
162 the library directory.
164 2002-02-13 Ravi Pratap <ravi@ximian.com>
166 * expression.cs (BetterFunction): Put back in what Miguel commented out
167 since it is the correct fix. The problem is elsewhere ;-)
169 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
170 parameters of the parms method are themselves compatible or not !
172 (StandardConversionExists): Fix very dangerous bug where we were forgetting
173 to check that a class implements an interface before saying that an implicit
174 conversion was allowed. Use ImplementsInterface to do the checking.
176 2002-02-13 Miguel de Icaza <miguel@ximian.com>
178 * class.cs (Method.Define): Track whether we are an explicit
179 implementation or not. And only call DefineMethodOverride if we
180 are an explicit implementation.
182 (Property.DefineMethod): Ditto.
184 2002-02-11 Ravi Pratap <ravi@ximian.com>
186 * expression.cs (BetterFunction): Catch hideous bug which was
187 preventing us from detecting ambiguous calls due to implicit casts i.e
190 2002-01-29 Miguel de Icaza <miguel@ximian.com>
192 * support.cs (Pair): Remove un-needed method. I figured why I was
193 getting the error in cs-parser.jay, the variable in a foreach loop
194 is readonly, and the compiler does not really treat this as a variable.
196 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
197 instead of EQUALS in grammar.
199 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
201 * expression.cs (Unary.DoResolve): Check whether the argument is
204 2002-01-28 Miguel de Icaza <miguel@ximian.com>
206 * support.cs: Api for Pair to set a value. Despite the fact that
207 the variables are public the MS C# compiler refuses to compile
208 code that accesses the field if the variable is part of a foreach
211 * statement.cs (Fixed): Begin implementation of the fixed
214 (Block.AddVariable): Return the VariableInfo on success and null
215 on failure instead of true/false.
217 * cs-parser.jay (foreach): Catch errors on variables already
218 defined (we were ignoring this value before) and properly unwind
221 (fixed_statement): grammar for the fixed statement.

225 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
226 pointer types to be incretemented.
230 * cs-parser.jay (pointer_member_access): Implement
231 expr->IDENTIFIER production.

240 use in non-unsafe context).
242 (SimpleName.DoResolve): Check for pointers in field access on safe
245 (Expression.LoadFromPtr): Factor the load-indirect code in this

258 * cs-parser.jay (non_expression_type): Add productions for pointer
261 * expression.cs (Invocation.EmitCall): Remove chunk of buggy
262 code. We should not use force into static mode if the method is
263 not virtual. Fixes bug in MIS
265 * statement.cs (Do.Emit, While.Emit, For.Emit,
266 Statement.EmitBoolExpression): Add support to Do and While to
267 propagate infinite loop as `I do return' semantics.
269 Improve the For case to also test for boolean constants.
271 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
272 to the list of attributes we can add.
274 Remove `EmitContext' argument.
276 * class.cs (Method.Define): Apply parameter attributes.
277 (Constructor.Define): Apply parameter attributes.
278 (MethodCore.LabelParameters): Move here the core of labeling
281 * support.cs (ReflectionParameters.ParameterModifier,
282 InternalParameters.ParameterModifier): Use IsByRef on the type and
283 only return the OUT bit for these parameters instead of in/out/ref
286 This is because I miss-understood things. The ParameterInfo.IsIn
287 and IsOut represent whether the parameter has the [In] and [Out]
290 2002-01-22 Miguel de Icaza <miguel@ximian.com>
292 * ecore.cs (FieldExpr.Emit): Release temporaries.
294 * assign.cs (LocalTemporary.Release): new function.
296 * codegen.cs (EmitContext.GetTemporaryStorage,
297 EmitContext.FreeTemporaryStorage): Rework the way we deal with

301 2002-01-21 Miguel de Icaza <miguel@ximian.com>
303 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we

306 2002-01-19 Miguel de Icaza <miguel@ximian.com>
308 * driver.cs: Compute dynamically the system directory.
310 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
311 Slower, but more generally useful. Used by the abstract
312 registering implementation.
314 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
315 the rules for the special rule on Type/instances. First check if
316 we have the same name, and if so, try that special static path
317 rather than the instance path.
319 2002-01-18 Miguel de Icaza <miguel@ximian.com>
321 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
324 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
325 Enum, ValueType, Delegate or Array for non-corlib compiles.
327 * cs-tokenizer.cs: Catch long identifiers (645)
329 * typemanager.cs (IndexerPropetyName): Ravi never tested this
332 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
333 fix, we were returning too early, so we were not registering
334 pending methods from abstract classes.
336 Do not register pending methods if the class is abstract.
338 * expression.cs (Conditional.DoResolve): Report circular implicit
339 conversions when we neecd to compute it for conditional
342 (Is.DoResolve): If the expression is always of the provided type,
343 flag warning 183. If the expression can not ever be of the
344 provided type flag warning 184.
346 * class.cs: Catch 169 as well.
348 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
351 2002-01-18 Nick Drochak <ndrochak@gol.com>
353 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.

357 * interface.cs: (PopulateMethod): Check for pointers being defined
358 only if the unsafe context is active.
359 (PopulateProperty): ditto.
360 (PopulateIndexer): ditto.
362 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
363 specified. If pointers are present, make sure that they are
364 present in an unsafe context.
365 (Constructor, Constructor.Define): ditto.
366 (Field, Field.Define): ditto.
367 (Property, Property.Define): ditto.
368 (Event, Event.Define): ditto.
370 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
371 hashtable if there are classes or structs defined.
373 * expression.cs (LocalVariableReference.DoResolve): Simplify this
374 code, as the constant resolution moved.
376 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
377 the metadata, so we can flag error 133.
379 * decl.cs (MemberCore.UnsafeOK): New function to test that a
380 pointer is being declared in an unsafe context.
382 2002-01-16 Miguel de Icaza <miguel@ximian.com>
384 * modifiers.cs (Modifiers.Check): Require a Location argument.
385 Report error 227 for Unsafe use.
387 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
389 * statement.cs (For.Emit): If the test is null, then report that
390 we do `return', as we wont reach anything afterwards.
392 (Switch.SwitchGoverningType): Track the expression that matched
395 * driver.cs: Allow negative numbers as an error code to flag.
397 * cs-parser.jay: Handle 1551.
399 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
401 2002-01-15 Miguel de Icaza <miguel@ximian.com>
403 * cs-parser.jay: Report 1518 (type declaration can only contain
404 class, struct, interface, enum or delegate)
406 (switch_label): Report 1523 (keywords `case' or `default' must
409 (opt_switch_sections): Report 1522 (empty switch)

417 access not allowed in static code)
419 2002-01-11 Ravi Pratap <ravi@ximian.com>
421 * typemanager.cs (IsPointerType): Utility method which we are going
424 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
425 the object type, so we take care of that.
427 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
429 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
430 added to non-params parameters :-)
432 * typemanager.cs (CSharpName): Include 'void' type too.
434 (void_ptr_type): Include in the set of core types.
436 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
439 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
442 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
443 completely forgotten about it.
445 2002-01-10 Ravi Pratap <ravi@ximian.com>
447 * cs-parser.jay (pointer_type): Add. This begins our implementation
448 of parsing rules for unsafe code.
450 (unsafe_statement): Implement.
452 (embedded_statement): Modify to include the above.
454 * statement.cs (Unsafe): Implement new class for unsafe blocks.
456 * codegen.cs (EmitContext.InUnsafe): Add. This determines
457 if the current context is an unsafe one.
459 * cs-parser.jay (local_variable_pointer_type): Since local variable types
460 are handled differently, we need separate rules for them.
462 (local_variable_declaration): Update to use local_variable_pointer_type
463 to allow variable declarations of unmanaged pointer types.
465 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
468 * ../errors/cs0214.cs : Add.
470 2002-01-16 Nick Drochak <ndrochak@gol.com>

488 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
491 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
492 this routine and will wrap the call in a try/catch block. Deal
495 2002-01-11 Miguel de Icaza <miguel@ximian.com>
497 * ecore.cs (Expression.MemberLookup): instead of taking a
498 parameter `same_type' that was used to tell whether we could
499 access private members we compute our containing type from the
502 (FieldExpr): Added partial support for volatile fields. This does
503 not work for volatile fields exposed from assemblies, as I can not
504 figure out how to extract the modreq from it.
506 Updated all the source files to use this.
508 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
509 because it is referenced by MemberLookup very often.
511 2002-01-09 Ravi Pratap <ravi@ximian.com>
513 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
514 TypeBuilder.GetCustomAttributes to retrieve what we need.
516 Get rid of redundant default_member_attr_type as this is the same as
517 default_member_type which already exists.
519 * interface.cs, attribute.cs : Update accordingly.
521 2002-01-08 Miguel de Icaza <miguel@ximian.com>
523 * typemanager.cs: Enable IndexerPropertyName again. It does not
524 work for TYpeBuilders though. Ravi, can you please fix this?
526 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
528 * expression.cs (Argument.Emit): Handle the case of ref objects
529 being passed to ref functions;
531 (ParameterReference.EmitLoad): Loads the content of the pointer
532 without dereferencing.
534 2002-01-07 Miguel de Icaza <miguel@ximian.com>
536 * cs-tokenizer.cs: Implemented the pre-processing expressions.
538 2002-01-08 Ravi Pratap <ravi@ximian.com>

544 * expression.cs (ConversionExists): Remove as it is completely obsolete.
546 (BetterConversion): Fix extremely trivial bug where we were referring to
547 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
550 * ../errors/bug16.cs : Add although we have fixed it.
552 2002-01-07 Miguel de Icaza <miguel@ximian.com>
554 * expression.cs (BaseIndexer): Begin implementation.
556 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
558 * cs-parser.jay (indexer_declarator): Use qualified_identifier
559 production directly to remove a shift/reduce, and implement
560 explicit interface implementation.
562 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
563 after a floating point suffix.
565 * expression.cs (DoNumericPromotions): Improved the conversion for
566 uint/uint. If we have a constant, we avoid doing a typecast to a
569 * class.cs (Indexer): Implement explicit interface implementation
572 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
574 * class.cs: make the default instance constructor public and hidebysig.
576 2001-01-03 Ravi Pratap <ravi@ximian.com>
578 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
579 so we can call it from elsewhere.
581 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
582 we emit it internally if the class has a defined indexer; otherwise the user
583 emits it by decorating the class definition with the DefaultMemberAttribute.
585 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
586 attribute is not used on a type which defines an indexer.
588 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
589 character when we skip whitespace.
591 * ../errors/cs0646.cs : Add.
593 2002-01-03 Miguel de Icaza <miguel@ximian.com>
595 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120

603 * class.cs (Property, Method, Indexer): Emit Final flag on the
604 method if we are an interface implementation and we are not
607 * ecore.cs (PropertyExpr): New public field `IsBase', tells
608 whether this property is referencing a `base' method.
610 * expression.cs (Invocation.EmitCall): take an extra argument:
611 is_base, this is used to determine whether the `call' or
612 `callvirt' opcode should be used.
615 * delegate.cs: update EmitCall.
617 * class.cs (Method.Define): Set NewSlot for the cases where we are
618 not implementing an interface method.
620 (Property.Define): ditto.
622 2002-01-02 Miguel de Icaza <miguel@ximian.com>
624 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
625 'r'. Allows mcs to parse itself fully.
627 2002-01-02 Ravi Pratap <ravi@ximian.com>
629 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
630 of the number of initializers that require the InitializeArray method.
632 (CheckIndices): Store the Expression in all cases - not the plain value. Also
633 update the above field where necessary.
635 (MakeByteBlob): Update accordingly.
637 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
640 (EmitDynamicInitializers): Update in accordance with the new optimization.
642 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
645 * cs-parser.jay : Fix some glaring errors I introduced.
647 2002-01-01 Ravi Pratap <ravi@ximian.com>
649 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
650 so that we can check for name clashes there too.
652 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
653 for interface indexers.
655 * interfaces.cs (Define): Emit the default member attribute.
657 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
658 variable was being referred to while setting the value ;-)
660 2002-01-01 Miguel de Icaza <miguel@ximian.com>
662 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
663 byte-by-byte information when we know the data is zero.
665 Make the block always a multiple of 4, because
666 DefineInitializedData has a bug.
668 * assign.cs: Fix, we should assign from the temporary, not from
671 * expression.cs (MakeByteBlob): Fix my incorrect code.
673 2001-12-31 Miguel de Icaza <miguel@ximian.com>
675 * typemanager.cs (EnumToUnderlying): This function is used to get
676 the underlying type from an enumeration, because it does not
679 * constant.cs: Use the I4_S form for values between -128 and 127.
681 * statement.cs (Block.LookupLabel): Looks up a label.
682 (Block): Drop support for labeled blocks.
684 (LabeledStatement): New kind of statement that represents a label
687 (Goto): Finally implement this bad boy.
689 * cs-parser.jay: Update to reflect new mechanism to implement
692 2001-12-30 Miguel de Icaza <miguel@ximian.com>
694 * codegen.cs (EmitContext.This): a codegen property that keeps the
695 a single instance of this instead of creating many different this
698 * delegate.cs (Delegate.DoResolve): Update to use the property;
700 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
702 * expression.cs (BaseAccess.DoResolve): Ditto.
704 2001-12-29 Ravi Pratap <ravi@ximian.com>
706 * typemanager.cs (methodimpl_attr_type): Add to hold the type
707 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
709 (InitCoreTypes): Update accordingly.
711 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
712 so we can quickly store the state.
714 (ApplyAttributes): Set the correct implementation flags
715 for InternalCall methods.
717 2001-12-29 Miguel de Icaza <miguel@ximian.com>
719 * expression.cs (EmitCall): if a method is not virtual, then do
720 not use callvirt on it.
722 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
723 user defined stuff) requires the use of stobj, which takes an
724 address on the stack instead of an array and an index. So emit
725 the Ldelema operation for it.
727 (EmitStoreOpcode): Use stobj for valuetypes.
729 (UnaryMutator.EmitCode): Use the right 1 value depending on
730 whether we are dealing with int64/uint64, float or doubles.
732 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
733 constructors that I implemented last night.
735 (Constructor.IsDefault): Fix to work properly for static
738 * cs-parser.jay (CheckDef): report method signature errors.
739 Update error number 103 to be 132.
741 * decl.cs: New AdditionResult enumeration value: MethodExists.
742 Although we do this check for methods later on in the semantic
743 analysis, catching repeated default constructors is so easy that
746 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
749 (ParameterReference.EmitAssign, Emit): handle
752 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
753 (ArrayAccess.EmitStoreOpcode): ditto.
755 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
757 * expression.cs (MakeByteBlob): Complete all the missing types
758 (uint, short, ushort, byte, sbyte)
760 * class.cs: Only init instance field initializers on instance
763 Rename `constructors' to instance_constructors.
765 (TypeContainer.AddConstructor): Only add constructors to the list
768 Make sure that we handle default_static_constructor independently
769 everywhere where we handle instance_constructors
771 2001-12-28 Miguel de Icaza <miguel@ximian.com>
773 * class.cs: Do not lookup or create a base initializer for a
776 (ConstructorInitializer.Resolve): use the proper type to lookup
779 * cs-parser.jay: Report error 1585 (modifiers between type and name).
781 * enum.cs, interface.cs: Remove CloseType, this is taken care by
784 * decl.cs: CloseType is now an virtual method, the default
785 implementation just closes this type.
787 2001-12-28 Ravi Pratap <ravi@ximian.com>
789 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
790 to PreserveSig by default. Also emit HideBySig on such methods.
792 Basically, set the defaults to standard values.
794 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
795 argument, if candidate is better, it can't be worse than the best !
797 (Invocation): Re-write bits to differentiate between methods being
798 applicable in their expanded form and their normal form - for params
801 Get rid of use_standard everywhere as only standard conversions are allowed
802 in overload resolution.
804 More spec conformance.
806 2001-12-27 Miguel de Icaza <miguel@ximian.com>
808 * driver.cs: Add --timestamp, to see where the compiler spends
811 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
812 `this' in static code.
814 (SimpleName.DoResolve): Implement in terms of a helper function
815 that allows static-references to be passed upstream to
818 (Expression.ResolveWithSimpleName): Resolve specially simple
819 names when called by MemberAccess to implement the special
822 (Expression.ImplicitReferenceConversion): Handle conversions from
823 Null to reference types before others, as Null's type is
826 * expression.cs (Invocation.EmitCall): Handle the special case of
827 calling methods declared on a reference type from a ValueType
828 (Base classes System.Object and System.Enum)
830 (MemberAccess.Resolve): Only perform lookups on Enumerations if
831 the left hand side is a TypeExpr, not on every enumeration.
833 (Binary.Resolve): If types are reference types, then do a cast to
834 object on operators != and == of both arguments.
836 * typemanager.cs (FindMembers): Extract instance and static
837 members if requested.
839 * interface.cs (PopulateProperty): Use void_type instead of null
840 as the return type for the setter method.
842 (PopulateIndexer): ditto.
844 2001-12-27 Ravi Pratap <ravi@ximian.com>
846 * support.cs (ReflectionParameters): Fix minor bug where we
847 were examining the wrong parameter for the ParamArray attribute.
849 Cope with requests for the type of the parameter at position
850 greater than the params parameter's. We now return the element
851 type of the params array as that makes more sense.
853 * expression.cs (Invocation.IsParamsMethodApplicable): Update
854 accordingly as we no longer have to extract the element type
857 (Invocation.OverloadResolve): Update.
859 2001-12-27 Miguel de Icaza <miguel@ximian.com>
861 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
862 against IEnumerator, test whether the return value is a descendant
863 of the IEnumerator interface.
865 * class.cs (Indexer.Define): Use an auxiliary method to implement
866 the other bits of the method definition. Begin support for
867 explicit interface implementation.
869 (Property.DefineMethod): Use TypeManager.void_type instead of null
870 for an empty return value.
872 2001-12-26 Miguel de Icaza <miguel@ximian.com>
874 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
875 dealing with a FieldExpr which is composed of a FieldBuilder, in
876 the code path we did extract the constant, but we should have
877 obtained the underlying value to be able to cast it (otherwise we
878 end up in an infinite loop, this is what Ravi was running into).
880 (ArrayCreation.UpdateIndices): Arrays might be empty.
882 (MemberAccess.ResolveMemberAccess): Add support for section
883 14.5.4.1 that deals with the special case of E.I when E is a type
884 and something else, that I can be a reference to a static member.
886 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
887 handle a particular array type to create byte blobs, it is just
888 something we dont generate byteblobs for.
890 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
893 * location.cs (Push): remove the key from the hashtable that we
894 are about to add. This happens for empty files.
896 * driver.cs: Dispose files after we have parsed them.
898 (tokenize): new function that only runs the tokenizer on its
899 input, for speed testing.
901 2001-12-26 Ravi Pratap <ravi@ximian.com>
903 * class.cs (Event.Define): Define the private field only if there
904 are no accessors defined.
906 * expression.cs (ResolveMemberAccess): If there is no associated
907 field with the event, that means we have an event defined with its
908 own accessors and we should flag error cs0070 since transforming
909 ourselves into a field is not valid in that case.
911 * ecore.cs (SimpleName.DoResolve): Same as above.
913 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
914 and charset to sane values.
916 2001-12-25 Ravi Pratap <ravi@ximian.com>
918 * assign.cs (DoResolve): Perform check on events only if they
919 are being accessed outside the declaring type.
921 * cs-parser.jay (event_declarations): Update rules to correctly
922 set the type of the implicit parameter etc.
924 (add_accessor, remove_accessor): Set current local parameters.
926 * expression.cs (Binary): For delegate addition and subtraction,
927 cast the return value from the method into the appropriate delegate
930 2001-12-24 Ravi Pratap <ravi@ximian.com>
932 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
933 of these as the workaround is unnecessary.
935 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
936 delegate data - none of that is needed at all.
938 Re-write bits to extract the instance expression and the delegate method
941 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
944 * attribute.cs (ApplyAttributes): New method to take care of common tasks
945 of attaching attributes instead of duplicating code everywhere.
947 * everywhere : Update code to do attribute emission using the above method.
949 2001-12-23 Miguel de Icaza <miguel@ximian.com>
951 * expression.cs (IsParamsMethodApplicable): if there are not
952 parameters, return immediately.
954 * ecore.cs: The 0 literal can be implicity converted to an enum
957 (SimpleName.DoResolve): First lookup the type, then lookup the
960 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
961 want to get its address. If the InstanceExpression is not
962 addressable, store the result in a temporary variable, then get
965 * codegen.cs: Only display 219 errors on warning level or above.
967 * expression.cs (ArrayAccess): Make it implement the
968 IMemoryLocation interface.
970 (Binary.DoResolve): handle the operator == (object a, object b)
971 and operator != (object a, object b) without incurring into a
972 BoxedCast (because 5 != o should never be performed).
974 Handle binary enumerator operators.
976 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
977 value type, otherwise use Ldelem_ref.
979 Use precomputed names;
981 (AddressOf): Implement address of
983 * cs-parser.jay (labeled_statement): Fix recursive block
984 addition by reworking the production.
986 * expression.cs (New.DoEmit): New has a special case:
988 If we are dealing with a ValueType, we have a few
989 situations to deal with:
991 * The target of New is a ValueType variable, that is
992 easy, we just pass this as the variable reference
994 * The target of New is being passed as an argument,
995 to a boxing operation or a function that takes a
998 In this case, we need to create a temporary variable
999 that is the argument of New.
1002 2001-12-23 Ravi Pratap <ravi@ximian.com>
1004 * rootcontext.cs (LookupType): Check that current_type is not null before
1005 going about looking at nested types.
1007 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
1008 not implement the IAssignMethod interface any more.
1010 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
1011 where we tranform them into FieldExprs if they are being resolved from within
1014 * ecore.cs (SimpleName.DoResolve): Do the same here.
1016 * assign.cs (DoResolve, Emit): Clean up code considerably.
1018 * ../errors/bug10.cs : Add.
1020 * ../errors/cs0070.cs : Add.
1022 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
1024 * assign.cs : Get rid of EventIsLocal everywhere.
1026 2001-12-23 Miguel de Icaza <miguel@ximian.com>
1028 * ecore.cs (ConvertIntLiteral): finished the implementation.
1030 * statement.cs (SwitchLabel): Convert the value we are using as a
1031 key before looking up the table.
1033 2001-12-22 Miguel de Icaza <miguel@ximian.com>
1035 * codegen.cs (EmitTopBlock): Require a Location argument now.
1037 * cs-parser.jay (constructor_declarator): We need to setup
1038 current_local_parameters before we parse the
1039 opt_constructor_initializer, to allow the variables to be bound
1040 to the constructor arguments.
1042 * rootcontext.cs (LookupType): First lookup nested classes in our
1043 class and our parents before we go looking outside our class.
1045 * expression.cs (ConstantFold): Extract/debox the values at the
1048 * rootcontext.cs (EmitCode): Resolve the constants first before we
1049 resolve the types. This is not really needed, but it helps debugging.
1051 * statement.cs: report location.
1053 * cs-parser.jay: pass location to throw statement.
1055 * driver.cs: Small bug fix.
1057 * report.cs: Updated format to be 4-zero filled digits.
1059 2001-12-22 Ravi Pratap <ravi@ximian.com>
1061 * expression.cs (CheckIndices): Fix minor bug where the wrong
1062 variable was being referred to ;-)
1064 (DoEmit): Do not call EmitStaticInitializers when the
1065 underlying type is System.Object.
1067 2001-12-21 Ravi Pratap <ravi@ximian.com>
1069 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
1070 and do the usual workaround for SRE.
1072 * class.cs (MyEventBuilder.EventType): New member to get at the type
1073 of the event, quickly.
1075 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
1077 * assign.cs (Assign.DoResolve): Handle the case when the target
1078 is an EventExpr and perform the necessary checks.
1080 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
1083 (SimpleName.MemberStaticCheck): Include check for EventExpr.
1085 (EventExpr): Set the type in the constructor itself since we
1086 are meant to be born fully resolved.
1088 (EventExpr.Define): Revert code I wrote earlier.
1090 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
1091 instance expression is null. The instance expression is a This in that case
1092 or a null, depending on whether it is a static method or not.
1094 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
1095 refers to more than one method.
1097 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
1098 and accordingly flag errors.
1100 2001-12-21 Miguel de Icaza <miguel@ximian.com>
1102 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
1104 2001-12-22 Miguel de Icaza <miguel@ximian.com>
1106 * location.cs (ToString): Provide useful rutine.
1108 2001-12-21 Miguel de Icaza <miguel@ximian.com>
1110 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
1111 objects, return the actual integral boxed.
1113 * statement.cs (SwitchLabel): define an ILLabel for each
1116 (Switch.CheckSwitch): If the value is a Literal, extract
1117 the underlying literal.
1119 Also in the unused hashtable we had, add the SwitchLabel so we can
1120 quickly look this value up.
1122 * constant.cs: Implement a bunch of new constants. Rewrite
1123 Literal based on this. Made changes everywhere to adapt to this.
1125 * expression.cs (Expression.MakeByteBlob): Optimize routine by
1126 dereferencing array only once, and also copes with enumrations.
1128 bytes are two bytes wide, not one.
1130 (Cast): Perform constant conversions.
1132 * ecore.cs (TryImplicitIntConversion): Return literals instead of
1133 wrappers to the literals here.
1135 * expression.cs (DoNumericPromotions): long literals can converted
1136 to ulong implicity (this is taken care of elsewhere, but I was
1139 * ecore.cs (Expression.Literalize): Make the return type Literal,
1140 to improve type checking.
1142 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
1144 2001-12-20 Miguel de Icaza <miguel@ximian.com>
1146 * literal.cs: Revert code from ravi that checked the bounds. The
1147 bounds are sane by the definition of the type itself.
1149 * typemanager.cs: Fix implementation of ImplementsInterface. We
1150 need to actually look up in our parent hierarchy for interfaces
1153 * const.cs: Use the underlying type for enumerations
1155 * delegate.cs: Compute the basename for the delegate creation,
1156 that should fix the delegate test case, and restore the correct
1157 Type Lookup semantics in rootcontext
1159 * rootcontext.cs: Revert Ravi's last patch. The correct way of
1160 referencing a nested type with the Reflection API is using the "+"
1163 * cs-parser.jay: Do not require EOF token at the end.
1165 2001-12-20 Ravi Pratap <ravi@ximian.com>
1167 * rootcontext.cs (LookupType): Concatenate type names with
1168 a '.' instead of a '+' The test suite passes again.
1170 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
1171 field of the enumeration.
1173 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
1174 the case when the member is an EventExpr.
1176 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
1177 static has an associated instance expression.
1179 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
1181 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
1183 * class.cs (Event.Define): Register event and perform appropriate checks
1186 We define the Add and Remove methods even if the use provides none because
1187 in that case, we provide default implementations ourselves.
1189 Define a private field of the type of the event. This is done by the CSC compiler
1190 and we should be doing it too ;-)
1192 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
1193 More methods we use in code we generate.
1195 (multicast_delegate_type, delegate_type): Two separate types since the distinction
1198 (InitCoreTypes): Update accordingly for the above.
1200 * class.cs (Event.Emit): Generate code for default accessors that we provide
1202 (EmitDefaultMethod): Do the job in the above.
1204 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
1207 2001-12-20 Miguel de Icaza <miguel@ximian.com>
1209 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
1210 builders even if we were missing one.
1212 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
1213 pass the Basename as our class name instead of the Name. The
1214 basename will be correctly composed for us.
1216 * parameter.cs (Paramters): Now takes a Location argument.
1218 * decl.cs (DeclSpace.LookupType): Removed convenience function and
1219 make all the code call directly LookupType in RootContext and take
1220 this chance to pass the Location information everywhere.
1222 * Everywhere: pass Location information.
1224 2001-12-19 Miguel de Icaza <miguel@ximian.com>
1226 * class.cs (Constructor.Define): Updated way of detecting the
1227 length of the parameters.
1229 (TypeContainer.DefineType): Use basename as the type name for
1232 (TypeContainer.Define): Do not recursively define types here, as
1233 definition is taken care in order by the RootContext.
1235 * tree.cs: Keep track of namespaces in a per-file basis.
1237 * parameter.cs (Parameter.ComputeSignature): Update to use
1240 (Parameters.GetSignature): ditto.
1242 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
1243 instead of a TypeContainer.
1245 (Interface.SemanticAnalysis): Use `this' instead of our parent to
1246 resolve names. Because we need to be resolve in our context, not
1249 * driver.cs: Implement response files.
1251 * class.cs (TypeContainer.DefineType): If we are defined, do not
1254 (Event.Emit): Emit the code for add/remove handlers.
1255 (Event.Define): Save the MethodBuilders for add/remove.
1257 * typemanager.cs: Use pair here too.
1259 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
1260 DictionaryEntry requires the first argument to be non-null.
1262 (enum_declaration): Compute full name for registering the
1265 (delegate_declaration): Instead of using
1266 formal_parameter_list, use opt_formal_parameter_list as the list
1269 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
1270 (EventParsing): New property that controls whether `add' and
1271 `remove' are returned as tokens or identifiers (for events);
1273 2001-12-19 Ravi Pratap <ravi@ximian.com>
1275 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
1276 use MyEventBuilder only and let it wrap the real builder for us.
1278 (MyEventBuilder): Revamp constructor etc.
1280 Implement all operations that we perform on EventBuilder in precisely the same
1283 (FindMembers): Update to use the EventBuilder member.
1285 (Event.Emit): Update accordingly.
1287 2001-12-18 Ravi Pratap <ravi@ximian.com>
1289 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
1290 by calling the appropriate methods.
1292 (GetCustomAttributes): Make stubs as they cannot possibly do anything
1295 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
1297 2001-12-17 Ravi Pratap <ravi@ximian.com>
1299 * delegate.cs (Delegate.Populate): Check that the return type
1300 and various parameters types are indeed accessible.
1302 * class.cs (Constructor.Define): Same here.
1304 (Field.Define): Ditto.
1306 (Event.Define): Ditto.
1308 (Operator.Define): Check that the underlying Method defined itself
1309 correctly - so it's MethodBuilder should not be null.
1311 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
1312 expression happens to be null.
1314 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
1315 members but as of now we don't seem to be able to do anything really useful with it.
1317 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
1318 not the EventBuilder.
1320 2001-12-18 Miguel de Icaza <miguel@ximian.com>
1322 * cs-tokenizer.cs: Add support for defines.
1323 Add support for #if, #elif, #else, #endif
1325 (eval_var): evaluates a variable.
1326 (eval): stubbed for evaluating functions.
1328 * cs-parser.jay: Pass the defines information
1330 * driver.cs: Add --define command line option.
1332 * decl.cs: Move MemberCore here.
1334 Make it the base class for DeclSpace. This allows us to catch and
1335 report 108 and 109 for everything now.
1337 * class.cs (TypeContainer.Define): Extract all the members
1338 before populating and emit the warning 108 (new keyword required
1339 to override) instead of having each member implement this.
1341 (MemberCore.Define): New abstract method, we will be using this in
1342 the warning reporting engine in Populate.
1344 (Operator.Define): Adjust to new MemberCore protocol.
1346 * const.cs (Const): This does not derive from Expression, it is a
1347 temporary object we use to create fields, it is a MemberCore.
1349 * class.cs (Method.Define): Allow the entry point to be in a
1352 * driver.cs: Rewrite the argument handler to clean it up a bit.
1354 * rootcontext.cs: Made it just an auxiliary namespace feature by
1355 making everything static.
1357 * driver.cs: Adapt code to use RootContext type name instead of
1360 * delegate.cs: Remove RootContext argument.
1362 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
1365 * class.cs (Event.Define): The lookup can fail.
1367 * cs-tokenizer.cs: Begin implementation of pre-procesor.
1369 * expression.cs: Resolve the this instance before invoking the code.
1371 2001-12-17 Miguel de Icaza <miguel@ximian.com>
1373 * cs-parser.jay: Add a production in element_access that allows
1374 the thing to become a "type" reference. This way we can parse
1375 things like "(string [])" as a type.
1377 Note that this still does not handle the more complex rules of
1381 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
1383 * ecore.cs: (CopyNewMethods): new utility function used to
1384 assemble the list of methods from running FindMembers.
1386 (MemberLookup): Rework FindMembers so that
1388 2001-12-16 Miguel de Icaza <miguel@ximian.com>
1390 * class.cs (TypeContainer): Remove Delegates who fail to be
1393 * delegate.cs (Populate): Verify that we dont get null return
1394 values. TODO: Check for AsAccessible.
1396 * cs-parser.jay: Use basename to emit error 574 (destructor should
1397 have the same name as container class), not the full name.
1399 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
1400 possible representation.
1402 Also implements integer type suffixes U and L.
1404 2001-12-15 Miguel de Icaza <miguel@ximian.com>
1406 * expression.cs (ArrayCreation.DoResolve): We need to do the
1407 argument resolution *always*.
1409 * decl.cs: Make this hold the namespace. Hold the root context as
1411 (LookupType): Move here.
1413 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
1415 * location.cs (Row, Name): Fixed the code, it was always returning
1416 references to the first file.
1418 * interface.cs: Register properties defined through interfaces.
1420 * driver.cs: Add support for globbing on the command line
1422 * class.cs (Field): Make it derive from MemberCore as well.
1425 2001-12-15 Ravi Pratap <ravi@ximian.com>
1427 * class.cs (Event::Define): Check that the type of the event is a delegate
1428 type else flag error #66.
1430 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
1433 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
1434 values of EntryPoint, CharSet etc etc.
1436 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
1438 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
1439 be null and we should ignore this. I am not sure if this is really clean. Apparently,
1440 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
1441 which needs this to do its work.
1443 * ../errors/cs0066.cs : Add.
1445 2001-12-14 Miguel de Icaza <miguel@ximian.com>
1447 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
1450 * class.cs: (MethodSignature.MethodSignature): Removed hack that
1451 clears out the parameters field.
1452 (MemberSignatureCompare): Cleanup
1454 (MemberCore): New base class used to share code between MethodCore
1457 (RegisterRequiredImplementations) BindingFlags.Public requires
1458 either BindingFlags.Instace or Static. Use instance here.
1460 (Property): Refactored code to cope better with the full spec.
1462 * parameter.cs (GetParameterInfo): Return an empty array instead
1465 * class.cs (Property): Abstract or extern properties have no bodies.
1467 * parameter.cs (GetParameterInfo): return a zero-sized array.
1469 * class.cs (TypeContainer.MethodModifiersValid): Move all the
1470 method modifier validation to the typecontainer so we can reuse
1473 (MethodCore.ParameterTypes): return an empty sized array of types.
1475 (Property.Define): Test property modifier validity.
1477 Add tests for sealed/override too.
1479 (Method.Emit): abstract or extern methods have no bodies.
1481 2001-12-14 Ravi Pratap <ravi@ximian.com>
1483 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
1486 (Method::Define, ::Emit): Modify accordingly.
1488 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
1490 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
1492 * makefile: Pass in /unsafe.

1496 * class.cs (MakeKey): Kill routine.
1498 * class.cs (TypeContainer.Define): Correctly define explicit
1499 method implementations (they require the full interface name plus
1502 * typemanager.cs: Deply the PtrHashtable here and stop using the
1503 lame keys. Things work so much better.
1505 This of course broke everyone who depended on `RegisterMethod' to
1506 do the `test for existance' test. This has to be done elsewhere.
1508 * support.cs (PtrHashtable): A hashtable that avoid comparing with
1509 the object stupid Equals method (because, that like fails all over
1510 the place). We still do not use it.
1512 * class.cs (TypeContainer.SetRequiredInterface,
1513 TypeContainer.RequireMethods): Killed these two routines and moved
1514 all the functionality to RegisterRequiredImplementations.
1516 (TypeContainer.RegisterRequiredImplementations): This routine now
1517 registers all the implementations required in an array for the
1518 interfaces and abstract methods. We use an array of structures
1519 which can be computed ahead of time to reduce memory usage and we
1520 also assume that lookups are cheap as most classes will not
1521 implement too many interfaces.
1523 We also avoid creating too many MethodSignatures.
1525 (TypeContainer.IsInterfaceMethod): Update and optionally does not
1526 clear the "pending" bit if we find that there are problems with
1529 (TypeContainer.VerifyPendingMethods): Update to report errors of
1530 methods that look like implementations but are not.
1532 (TypeContainer.Define): Add support for explicit interface method
1535 2001-12-12 Miguel de Icaza <miguel@ximian.com>
1537 * typemanager.cs: Keep track of the parameters here instead of
1538 being a feature of the TypeContainer.
1540 * class.cs: Drop the registration of parameters here, as
1541 InterfaceMethods are also interface declarations.
1543 * delegate.cs: Register methods with the TypeManager not only with
1544 the TypeContainer. This code was buggy.
1546 * interface.cs: Full registation here.
1548 2001-12-11 Miguel de Icaza <miguel@ximian.com>
1550 * expression.cs: Remove reducer for binary expressions, it can not
1553 * const.cs: Put here the code that used to go into constant.cs
1555 * constant.cs: Put here the code for constants, this is a new base
1558 * literal.cs: Make Literal derive from Constant.
1560 2001-12-09 Miguel de Icaza <miguel@ximian.com>
1562 * statement.cs (Return.Emit): Report error 157 if the user
1563 attempts to return from a finally block.
1565 (Return.Emit): Instead of emitting a return, jump to the end of
1568 * codegen.cs (EmitContext): ReturnValue, ReturnLabel: new
1569 LocalBuilder to store the result of the function. ReturnLabel is
1570 the target where we jump.
1573 2001-12-09 Radek Doulik <rodo@ximian.com>
1575 * cs-parser.jay: remember alias in current namespace
1577 * ecore.cs (SimpleName::DoResolve): use aliases for types or
1580 * class.cs (LookupAlias): lookup alias in my_namespace
1582 * namespace.cs (UsingAlias): add alias, namespace_or_type pair to
1584 (LookupAlias): lookup alias in this and if needed in parent
1587 2001-12-08 Miguel de Icaza <miguel@ximian.com>
1591 * rootcontext.cs: (ModuleBuilder) Made static, first step into
1592 making things static. I need this to avoid passing the
1593 TypeContainer when calling ParameterType.
1595 * support.cs (InternalParameters.ParameterType): Remove ugly hack
1596 that did string manipulation to compute the type and then call
1597 GetType. Use Parameter.ParameterType instead.
1599 * cs-tokenizer.cs: Consume the suffix for floating values.
1601 * expression.cs (ParameterReference): figure out whether this is a
1602 reference parameter or not. Kill an extra variable by computing
1603 the arg_idx during emission.
1605 * parameter.cs (Parameters.GetParameterInfo): New overloaded
1606 function that returns whether a parameter is an out/ref value or not.
1608 (Parameter.ParameterType): The type of the parameter (base,
1609 without ref/out applied).
1611 (Parameter.Resolve): Perform resolution here.
1612 (Parameter.ExternalType): The full type (with ref/out applied).
1614 * statement.cs (Using.Emit, Using.EmitExpression): Implement
1615 support for expressions on the using statement.
1617 2001-12-07 Miguel de Icaza <miguel@ximian.com>
1619 * statement.cs (Using.EmitLocalVariableDecls): Split the
1620 localvariable handling of the using statement.
1622 (Block.EmitMeta): Keep track of variable count across blocks. We
1623 were reusing slots on separate branches of blocks.
1625 (Try.Emit): Emit the general code block, we were not emitting it.
1627 Check the type of the declaration to be an IDisposable or
1628 something that can be implicity converted to it.
1630 Emit conversions if required.
1632 * ecore.cs (EmptyExpression): New utility class.
1633 (Expression.ImplicitConversionExists): New utility function.
1635 2001-12-06 Miguel de Icaza <miguel@ximian.com>
1637 * statement.cs (Using): Implement.
1639 * expression.cs (LocalVariableReference): Support read only variables.
1641 * statement.cs: Remove the explicit emit for the Leave opcode.
1642 (VariableInfo): Add a readonly field.
1644 2001-12-05 Miguel de Icaza <miguel@ximian.com>
1646 * ecore.cs (ConvCast): new class used to encapsulate the various
1647 explicit integer conversions that works in both checked and
1650 (Expression.ConvertNumericExplicit): Use new ConvCast class to
1651 properly generate the overflow opcodes.
1653 2001-12-04 Miguel de Icaza <miguel@ximian.com>
1655 * statement.cs: The correct type for the EmptyExpression is the
1656 element_type, not the variable type. Ravi pointed this out.
1658 2001-12-04 Ravi Pratap <ravi@ximian.com>
1660 * class.cs (Method::Define): Handle PInvoke methods specially
1661 by using DefinePInvokeMethod instead of the usual one.
1663 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
1664 above to do the task of extracting information and defining the method.
1666 2001-12-04 Ravi Pratap <ravi@ximian.com>
1668 * expression.cs (ArrayCreation::EmitStaticInitializers): Get rid
1669 of the condition for string type.

1686 2001-12-03 Miguel de Icaza <miguel@ximian.com>
1690 * statement.cs (GotoDefault), cs-parser.jay: Implement `goto
1693 (Foreach.Emit): Foreach on arrays was not setting
1694 up the loop variables (for break/continue).
1696 (GotoCase): Semi-implented.
1698 2001-12-03 Ravi Pratap <ravi@ximian.com>

1748 As that share bits of the implementation. Is returns a boolean,
1749 while As returns the Type that is being probed.
1751 2001-12-01 Ravi Pratap <ravi@ximian.com>
1753 * enum.cs (LookupEnumValue): Re-write various bits, return an object value
1754 instead of a Literal - much easier.
1756 (EnumInTransit): Remove - utterly useless :-)
1758 (Populate): Re-write bits - remove duplicate code etc. The code is much neater now.
1760 * expression.cs (MemberLookup): Cope with user-defined enums when they are in transit.

1855 directly from ArrayData now.
1857 (ExpectInitializers): Keep track of whether initializers are mandatory
1860 (Bounds): Make it a hashtable to prevent the same dimension being
1861 recorded for every element in that dimension.

1906 * expression.cs (ArrayCreation:Emit): Write preliminary code to do
1907 initialization from expressions but it is incomplete because I am a complete
1910 2001-11-22 Miguel de Icaza <miguel@ximian.com>
1912 * statement.cs (If.Emit): Fix a bug that generated incorrect code
1913 on If. Basically, we have to return `true' (ie, we do return to
1914 our caller) only if both branches of the if return.
1916 * expression.cs (Binary.Emit): LogicalOr and LogicalAnd are
1917 short-circuit operators, handle them as short circuit operators.

1920 (Cast.Cast): Take an expression as the target type.
1922 * cs-parser.jay (cast_expression): Remove old hack that only
1923 allowed a limited set of types to be handled. Now we take a
1924 unary_expression and we resolve to a type during semantic
1927 Use the grammar productions from Rhys to handle casts (this is
1928 not complete like Rhys syntax yet, we fail to handle that corner
1929 case that C# has regarding (-x), but we will get there.

1966 BindingFlags.Instance as well
1968 * ecore.cs (Expression.TryImplicitIntConversion): Wrap the result

1973 (Expression.ConvertExplicit): Add explicit type conversions done
1976 (Expression.ImplicitNumericConversion): Oops, forgot to test for

1980 2001-11-21 Miguel de Icaza <miguel@ximian.com>
1982 * cs-parser.jay (for_statement): Reworked the way For works: now
1983 we declare manually any variables that are introduced in
1984 for_initializer to solve the problem of having out-of-band code
1985 emition (that is what got for broken).
1987 (declaration_statement): Perform the actual variable declaration
1988 that used to be done in local_variable_declaration here.
1990 (local_variable_declaration): Do not declare anything, just pass
1991 the information on a DictionaryEntry
1993 2001-11-20 Ravi Pratap <ravi@ximian.com>
1995 * expression.cs (ArrayCreation::CheckIndices): The story continues :-) Complete

2058 we can use this elsewhere.
2060 * statement.cs: Finish implementation of foreach for single
2063 * cs-parser.jay: Use an out-of-band stack to pass information
2064 around, I wonder why I need this.
2066 foreach_block: Make the new foreach_block the current_block.
2068 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
2069 function used to return a static Parameters structure. Used for
2070 empty parameters, as those are created very frequently.
2072 * cs-parser.jay, class.cs: Use GetEmptyReadOnlyParameters
2074 2001-11-15 Ravi Pratap <ravi@ximian.com>
2076 * interface.cs : Default modifier is private, not public. The
2077 make verify test passes again.
2079 2001-11-15 Ravi Pratap <ravi@ximian.com>
2081 * support.cs (ReflectionParameters): Fix logic to determine

2115 2001-11-09 Miguel de Icaza <miguel@ximian.com>
2117 * enum.cs (Enum.Emit): Delay the lookup of loc until we run into

2138 * class.cs (Method.Emit): Clean up.
2140 * expression.cs (Argument.Resolve): Take another argument: the
2141 location where this argument is used. Notice that this is not
2142 part of the "Argument" class as to reduce the size of the
2143 structure (we know the approximate location anyways).

2146 complain with a 206.

2179 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
2180 enumerations that are used in heavily used structures derive from
2181 byte in a laughable and pathetic attempt to reduce memory usage.
2182 This is the kind of pre-optimzations that you should not do at
2183 home without adult supervision.
2185 * expression.cs (UnaryMutator): New class, used to handle ++ and
2186 -- separatedly from the other unary operators. Cleans up the
2187 code, and kills the ExpressionStatement dependency in Unary.
2189 (Unary): Removed `method' and `Arguments' from this class, making
2190 it smaller, and moving it all to SimpleCall, so I can reuse this
2191 code in other locations and avoid creating a lot of transient data
2192 strucutres when not required.

2259 * class.cs, rootcontext.cs : Update accordingly.
2261 * typemanager.cs (RegisterField, GetValue): Workarounds for the fact that

2267 of a fieldinfo using the above, when dealing with a FieldBuilder.

2357 as we had no way of defining nested enums !
2359 * rootcontext.cs : Adjust code accordingly.
2361 * typemanager.cs (AddEnumType): To keep track of enum types separately.
2363 2001-11-07 Ravi Pratap <ravi@ximian.com>

2655 * typemanager.cs (ImplementsInterface): interface might be null;
2656 Deal with this problem;
2658 Also, we do store negative hits on the cache (null values), so use
2659 this instead of calling t.GetInterfaces on the type everytime.

2844 of Delegate types for now.
2846 2001-10-18 Ravi Pratap <ravi@ximian.com>
2848 * delegate.cs (NewDelegate): New class to take care of delegate
2851 * expression.cs (New): Split the delegate related code out into
2852 the NewDelegate class.
2854 * delegate.cs (DelegateInvocation): New class to handle delegate
2857 * expression.cs (Invocation): Split out delegate related code into
2858 the DelegateInvocation class.
2860 2001-10-17 Ravi Pratap <ravi@ximian.com>
2862 * expression.cs (New::DoResolve): Implement delegate creation fully
2863 and according to the spec.
2865 (New::DoEmit): Update to handle delegates differently.
2867 (Invocation::FullMethodDesc): Fix major stupid bug thanks to me
2868 because of which we were printing out arguments in reverse order !
2870 * delegate.cs (VerifyMethod): Implement to check if the given method
2871 matches the delegate.

2925 loop and end of the loop).
2927 2001-10-15 Ravi Pratap <ravi@ximian.com>

2944 (IsDelegateType): Implement helper method.
2946 * delegate.cs (DefineDelegate): Use AddDelegateType instead of AddUserType.
2948 * expression.cs (New::DoResolve): Check if we are trying to instantiate a delegate type
2949 and accordingly handle it.
2951 * delegate.cs (Populate): Take TypeContainer argument.
2952 Implement bits to define the Invoke method. However, I still haven't figured out
2953 how to take care of the native int bit :-(
2955 * cs-parser.jay (delegate_declaration): Fixed the bug that I had introduced :-)
2956 Qualify the name of the delegate, not its return type !
2958 * expression.cs (ImplicitReferenceConversion): Implement guts of implicit array
2961 (StandardConversionExists): Checking for array types turns out to be recursive.
2963 (ConvertReferenceExplicit): Implement array conversion.

2969 * cs-parser.jay (delegate_declaration): Store the fully qualified
2970 name as it is a type declaration.
2972 * delegate.cs (ReturnType, Name): Rename members to these. Make them
2975 (DefineDelegate): Renamed from Define. Does the same thing essentially,
2976 as TypeContainer::DefineType.
2978 (Populate): Method in which all the definition of the various methods (Invoke)
2981 (Emit): Emit any code, if necessary. I am not sure about this really, but let's
2984 (CloseDelegate): Finally creates the delegate.

2998 provide the proper semantic access to properties.
3000 * expression.cs (Expression::ConvertReferenceExplicit): Implement
3001 a few more explicit conversions.
3003 * modifiers.cs: `NEW' modifier maps to HideBySig.

3006 ExpressionStatement, and support the EmitStatement code path.
3008 Perform get/set error checking, clean up the interface.

3028 (This::LValueResolve): Implement.
3030 (This::Store): Remove warning, assigning to `this' in structures
3033 (Invocation::Emit): Deal with invocation of
3034 methods on value types. We need to pass the address to structure
3035 methods rather than the object itself. (The equivalent code to
3036 emit "this" for structures leaves the entire structure on the
3037 stack instead of a pointer to it).
3039 (ParameterReference::DoResolve): Compute the real index for the
3040 argument based on whether the method takes or not a `this' pointer
3041 (ie, the method is static).
3043 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store
3044 value types returned from functions when we need to invoke a
3045 method on the sturcture.
3048 2001-10-11 Ravi Pratap <ravi@ximian.com>
3050 * class.cs (TypeContainer::DefineType): Method to actually do the business of
3051 defining the type in the Modulebuilder or Typebuilder. This is to take
3052 care of nested types which need to be defined on the TypeBuilder using
3055 (TypeContainer::GetClassBases): Implement. Essentially the code from the
3056 methods in RootContext, only ported to be part of TypeContainer.
3058 (TypeContainer::GetInterfaceOrClass): Ditto.
3060 (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
3062 * interface.cs (Interface::DefineInterface): New method. Does exactly
3063 what RootContext.CreateInterface did earlier, only it takes care of nested types
3066 (Interface::GetInterfaces): Move from RootContext here and port.
3068 (Interface::GetInterfaceByName): Same here.
3070 * rootcontext.cs (ResolveTree): Re-write.

3078 instead just use the name argument passed in as it is already fully
3081 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
3082 to TypeContainer mapping to see if a type is user-defined.
3084 * class.cs (TypeContainer::CloseType): Implement.
3086 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
3087 the default constructor.
3089 (TypeContainer::Populate): Fix minor bug which led to creating default constructors
3092 (Constructor::IsDefault): Fix up logic to determine if it is the default constructor
3094 * interface.cs (CloseType): Create the type here.
3096 * rootcontext.cs (CloseTypes): Re-write to recursively close types by running through
3099 Remove all the methods which are now in TypeContainer.

3110 * expression.cs (ImplicitReferenceConversion): handle null as well
3111 as a source to convert to any reference type.
3113 * statement.cs (Return): Perform any implicit conversions to
3114 expected return type.
3116 Validate use of return statement.
3118 * codegen.cs (EmitContext): Pass the expected return type here.
3120 * class.cs (Method, Constructor, Property): Pass expected return
3121 type to EmitContext.
3123 2001-10-09 Miguel de Icaza <miguel@ximian.com>
3125 * expression.cs: Make DoResolve take an EmitContext instead of a
3128 Replaced `l' and `location' for `loc', for consistency.
3130 (Error, Warning): Remove unneeded Tc argument.
3132 * assign.cs, literal.cs, constant.cs: Update to new calling
3135 * codegen.cs: EmitContext now contains a flag indicating whether
3136 code is being generated in a static method or not.
3138 * cs-parser.jay: DecomposeQI, new function that replaces the old
3139 QualifiedIdentifier. Now we always decompose the assembled
3140 strings from qualified_identifier productions into a group of
3143 2001-10-08 Miguel de Icaza <miguel@ximian.com>
3145 * rootcontext.cs: Deal with field-less struct types correctly now
3146 by passing the size option to Define Type.
3148 * class.cs: Removed hack that created one static field.
3150 2001-10-07 Miguel de Icaza <miguel@ximian.com>
3152 * statement.cs: Moved most of the code generation here.
3154 2001-10-09 Ravi Pratap <ravi@ximian.com>
3156 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
3159 (ElementAccess): Remove useless bits for now - keep checks as the spec
3162 2001-10-08 Ravi Pratap <ravi@ximian.com>
3164 * expression.cs (ElementAccess::DoResolve): Remove my crap code
3165 and start performing checks according to the spec.
3167 2001-10-07 Ravi Pratap <ravi@ximian.com>
3169 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use

3178 2001-10-06 Ravi Pratap <ravi@ximian.com>
3180 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
3181 except that user defined conversions are not included.
3183 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
3184 perform the conversion of the return type, if necessary.
3186 (New::DoResolve): Check whether we are creating an array or an object
3187 and accordingly do the needful.
3189 (New::Emit): Same here.
3191 (New::DoResolve): Implement guts of array creation.
3193 (New::FormLookupType): Helper function.
3195 2001-10-07 Miguel de Icaza <miguel@ximian.com>

3198 corresponding code generation bits to the statement classes.
3200 Added support for try/catch/finalize and throw.
3202 * cs-parser.jay: Added support for try/catch/finalize.
3204 * class.cs: Catch static methods having the flags override,
3205 virtual or abstract.
3207 * expression.cs (UserCast): This user cast was not really doing
3208 what it was supposed to do. Which is to be born in fully resolved
3209 state. Parts of the resolution were being performed at Emit time!
3213 2001-10-05 Miguel de Icaza <miguel@ximian.com>
3215 * expression.cs: Implicity convert the result from UserCast.
3217 2001-10-05 Ravi Pratap <ravi@ximian.com>
3219 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
3220 prevented it from working correctly.

3227 * typemanager.cs: Make the LookupTypeContainer function static,
3228 and not per-instance.
3230 * class.cs: Make static FindMembers (the one that takes a Type
3233 * codegen.cs: Add EmitForeach here.
3235 * cs-parser.jay: Make foreach a toplevel object instead of the
3236 inline expansion, as we need to perform semantic analysis on it.

3240 * expression.cs (Expression::ImplicitUserConversion): Rename to
3241 UserDefinedConversion.

3255 * expression.cs (Cast): Record location info.
3257 (Expression::ConvertExplicit): Take location argument.
3259 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
3260 to determine if we are doing explicit conversions.
3262 (UserCast::Emit): Update accordingly.
3264 (Expression::ConvertExplicit): Report an error if everything fails.
3266 * ../errors/cs0030.cs : Add.
3268 2001-10-04 Miguel de Icaza <miguel@ximian.com>
3270 * modifiers.cs: If the ABSTRACT keyword is present, also set the
3271 virtual and newslot bits.
3273 * class.cs (TypeContainer::RegisterRequiredImplementations):
3274 Record methods we need.
3276 (TypeContainer::MakeKey): Helper function to make keys for
3277 MethodBases, since the Methodbase key is useless.
3279 (TypeContainer::Populate): Call RegisterRequiredImplementations
3280 before defining the methods.
3282 Create a mapping for method_builders_to_methods ahead of time
3283 instead of inside a tight loop.
3285 (::RequireMethods): Accept an object as the data to set into the
3286 hashtable so we can report interface vs abstract method mismatch.
3288 2001-10-03 Miguel de Icaza <miguel@ximian.com>
3290 * report.cs: Make all of it static.
3292 * rootcontext.cs: Drop object_type and value_type computations, as
3293 we have those in the TypeManager anyways.
3295 Drop report instance variable too, now it is a global.
3297 * driver.cs: Use try/catch on command line handling.
3299 Add --probe option to debug the error reporting system with a test
3302 * report.cs: Add support for exiting program when a probe
3303 condition is reached.
3305 2001-10-03 Ravi Pratap <ravi@ximian.com>
3307 * expression.cs (Binary::DoNumericPromotions): Fix the case when
3308 we do a forcible conversion regardless of type, to check if
3309 ForceConversion returns a null.
3311 (Binary::error19): Use location to report error.
3313 (Unary::error23): Use location here too.
3315 * ../errors/cs0019.cs : Check in.
3317 * ../errors/cs0023.cs : Check in.
3319 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
3320 case of a non-null MethodInfo object with a length of 0 !
3322 (Binary::ResolveOperator): Flag error if overload resolution fails to find
3323 an applicable member - according to the spec :-)
3324 Also fix logic to find members in base types.
3326 (Unary::ResolveOperator): Same here.
3328 (Unary::report23): Change name to error23 and make first argument a TypeContainer
3329 as I was getting thoroughly confused between this and error19 :-)
3331 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
3332 (::FindMostEncompassedType): Implement.
3333 (::FindMostEncompassingType): Implement.
3334 (::StandardConversionExists): Implement.
3336 (UserImplicitCast): Re-vamp. We now need info about most specific
3337 source and target types so that we can do the necessary conversions.
3339 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
3340 mathematical union with no duplicates.
3342 2001-10-03 Miguel de Icaza <miguel@ximian.com>
3344 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
3345 in order from base classes to child classes, so that we can in
3346 child classes look up in our parent for method names and
3347 attributes (required for handling abstract, virtual, new, override
3348 constructs: we need to instrospect our base class, and if we dont
3349 populate the classes in order, the introspection might be
3350 incorrect. For example, a method could query its parent before
3351 the parent has any methods and would determine that the parent has
3352 no abstract methods (while it could have had them)).
3354 (RootContext::CreateType): Record the order in which we define the
3357 2001-10-02 Miguel de Icaza <miguel@ximian.com>
3359 * class.cs (TypeContainer::Populate): Also method definitions can
3360 fail now, keep track of this.
3362 (TypeContainer::FindMembers): Implement support for
3363 DeclaredOnly/noDeclaredOnly flag.
3365 (Constructor::Emit) Return the ConstructorBuilder.
3367 (Method::Emit) Return the MethodBuilder.
3368 Check for abstract or virtual methods to be public.
3370 * rootcontext.cs (RootContext::CreateType): Register all the
3371 abstract methods required for the class to be complete and the
3372 interface methods that must be implemented.
3374 * cs-parser.jay: Report error 501 (method requires body if it is
3375 not marked abstract or extern).
3377 * expression.cs (TypeOf::Emit): Implement.
3379 * typemanager.cs: runtime_handle_type, new global type.
3381 * class.cs (Property::Emit): Generate code for properties.
3383 2001-10-02 Ravi Pratap <ravi@ximian.com>
3385 * expression.cs (Unary::ResolveOperator): Find operators on base type
3386 too - we now conform exactly to the spec.
3388 (Binary::ResolveOperator): Same here.
3390 * class.cs (Operator::Define): Fix minor quirk in the tests.
3392 * ../errors/cs0215.cs : Added.
3394 * ../errors/cs0556.cs : Added.
3396 * ../errors/cs0555.cs : Added.
3398 2001-10-01 Miguel de Icaza <miguel@ximian.com>
3400 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
3401 single integer which is really efficient
3403 2001-10-01 Ravi Pratap <ravi@ximian.com>
3405 * expression.cs (Expression::ImplicitUserConversion): Use location
3406 even in the case when we are examining True operators.
3408 * class.cs (Operator::Define): Perform extensive checks to conform
3409 with the rules for operator overloading in the spec.

3412 some of the other conversions mentioned in the spec.
3414 * typemanager.cs (array_type): New static member for the System.Array built-in
3417 (cloneable_interface): For System.ICloneable interface.
3419 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
3420 we start resolving the tree and populating types.
3422 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
3424 2001-10-01 Miguel de Icaza <miguel@ximian.com>
3426 * expression.cs (Expression::ExprClassFromMemberInfo,
3427 Expression::Literalize): Create literal expressions from
3428 FieldInfos which are literals.
3430 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
3431 type casts, because they were wrong. The test suite in tests
3434 (ImplicitNumericConversion): ushort to ulong requires a widening
3437 Int32 constant to long requires widening cast as well.
3439 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
3440 for integers because the type on the stack is not i4.
3442 2001-09-30 Miguel de Icaza <miguel@ximian.com>
3444 * expression.cs (report118): require location argument.
3446 * parameter.cs: Do not dereference potential null value.
3448 * class.cs: Catch methods that lack the `new' keyword when
3449 overriding a name. Report warnings when `new' is used without
3450 anything being there to override.
3452 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
3454 * class.cs: Only add constructor to hashtable if it is non-null
3455 (as now constructors can fail on define).
3457 (TypeManager, Class, Struct): Take location arguments.
3459 Catch field instance initialization in structs as errors.
3461 accepting_filter: a new filter for FindMembers that is static so
3462 that we dont create an instance per invocation.
3464 (Constructor::Define): Catch errors where a struct constructor is
3467 * cs-parser.jay: Pass location information for various new
3470 * delegate.cs (Delegate): take a location argument.
3472 * driver.cs: Do not call EmitCode if there were problesm in the
3473 Definition of the types, as many Builders wont be there.
3475 * decl.cs (Decl::Decl): Require a location argument.
3477 * cs-tokenizer.cs: Handle properly hex constants that can not fit
3478 into integers, and find the most appropiate integer for it.
3480 * literal.cs: Implement ULongLiteral.
3482 * rootcontext.cs: Provide better information about the location of
3483 failure when CreateType fails.
3485 2001-09-29 Miguel de Icaza <miguel@ximian.com>
3487 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
3490 * expression.cs (Binary::CheckShiftArguments): Add missing type
3492 (Binary::ResolveOperator): Add type to the logical and and logical
3493 or, Bitwise And/Or and Exclusive Or code paths, it was missing
3496 (Binary::DoNumericPromotions): In the case where either argument
3497 is ulong (and most signed types combined with ulong cause an
3498 error) perform implicit integer constant conversions as well.
3500 2001-09-28 Miguel de Icaza <miguel@ximian.com>
3502 * expression.cs (UserImplicitCast): Method should always be
3504 (Invocation::BetterConversion): Simplified test for IntLiteral.
3506 (Expression::ImplicitNumericConversion): Split this routine out.
3507 Put the code that performs implicit constant integer conversions
3510 (Expression::Resolve): Become a wrapper around DoResolve so we can
3511 check eclass and type being set after resolve.
3513 (Invocation::Badness): Remove this dead function
3515 (Binary::ResolveOperator): Do not compute the expensive argumnets
3516 unless we have a union for it.
3518 (Probe::Emit): Is needs to do an isinst and then
3519 compare against null.
3521 (::CanConvert): Added Location argument. If the Location argument
3522 is null (Location.Null), then we do not report errors. This is
3523 used by the `probe' mechanism of the Explicit conversion. We do
3524 not want to generate an error for something that the user
3525 explicitly requested to be casted. But the pipeline for an
3526 explicit cast first tests for potential implicit casts.
3528 So for now, if the Location is null, it means `Probe only' to
3529 avoid adding another argument. Might have to revise this
3532 (ClassCast): New class used to type cast objects into arbitrary
3533 classes (used in Explicit Reference Conversions).
3535 Implement `as' as well.
3537 Reverted all the patches from Ravi below: they were broken:
3539 * The use of `level' as a mechanism to stop recursive
3540 invocations is wrong. That was there just to catch the
3541 bug with a strack trace but not as a way of addressing
3544 To fix the problem we have to *understand* what is going
3545 on and the interactions and come up with a plan, not
3546 just get things going.
3548 * The use of the type conversion cache that I proposed
3549 last night had an open topic: How does this work across
3550 protection domains. A user defined conversion might not
3551 be public in the location where we are applying the
3552 conversion, a different conversion might be selected
3553 (ie, private A->B (better) but public B->A (worse),
3554 inside A, A->B applies, but outside it, B->A will
3557 * On top of that (ie, even if the above is solved),
3558 conversions in a cache need to be abstract. Ie, `To
3559 convert from an Int to a Short use an OpcodeCast', not
3560 `To convert from an Int to a Short use the OpcodeCast on
3561 the variable 5' (which is what this patch was doing).
3563 2001-09-28 Ravi Pratap <ravi@ximian.com>
3565 * expression.cs (Invocation::ConversionExists): Re-write to use
3566 the conversion cache
3568 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
3569 cache all conversions done, not just user-defined ones.
3571 (Invocation::BetterConversion): The real culprit. Use ConversionExists
3572 to determine if a conversion exists instead of acutually trying to
3573 perform the conversion. It's faster too.
3575 (Expression::ConvertExplicit): Modify to use ConversionExists to check
3576 and only then attempt the implicit conversion.
3578 2001-09-28 Ravi Pratap <ravi@ximian.com>
3580 * expression.cs (ConvertImplicit): Use a cache for conversions
3581 already found. Check level of recursion and bail out if necessary.
3583 2001-09-28 Miguel de Icaza <miguel@ximian.com>

3596 * codegen.cs: remove unnneded code
3598 * expression.cs: Removed BuiltinTypeAccess class
3600 Fix the order in which implicit conversions are
3603 The previous fixed dropped support for boxed conversions (adding a
3604 test to the test suite now)
3606 (UserImplicitCast::CanConvert): Remove test for source being null,
3607 that code is broken. We should not feed a null to begin with, if
3608 we do, then we should track the bug where the problem originates
3609 and not try to cover it up here.
3611 Return a resolved expression of type UserImplicitCast on success
3612 rather than true/false. Ravi: this is what I was talking about,
3613 the pattern is to use a static method as a "constructor" for
3616 Also, do not create arguments until the very last minute,
3617 otherwise we always create the arguments even for lookups that
3618 will never be performed.
3620 (UserImplicitCast::Resolve): Eliminate, objects of type
3621 UserImplicitCast are born in a fully resolved state.
3623 * typemanager.cs (InitCoreTypes): Init also value_type
3626 * expression.cs (Cast::Resolve): First resolve the child expression.
3628 (LValue): Add new method AddressOf to be used by
3631 Change the argument of Store to take an EmitContext instead of an
3632 ILGenerator, because things like FieldExpr need to be able to call
3633 their children expression to generate the instance code.
3635 (Expression::Error, Expression::Warning): Sugar functions for
3638 (Expression::MemberLookup): Accept a TypeContainer instead of a
3639 Report as the first argument.
3641 (Expression::ResolvePrimary): Killed. I still want to improve
3642 this as currently the code is just not right.
3644 (Expression::ResolveMemberAccess): Simplify, but it is still
3647 (Unary::Resolve): Catch errors in AddressOf operators.
3649 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
3650 index to a byte for the short-version, or the compiler will choose
3651 the wrong Emit call, which generates the wrong data.
3653 (ParameterReference::Emit, ::Store): same.
3655 (FieldExpr::AddressOf): Implement.
3657 * typemanager.cs: TypeManager: made public variable instead of
3660 * driver.cs: document --fatal.
3662 * report.cs (ErrorMessage, WarningMessage): new names for the old
3663 Error and Warning classes.
3665 * cs-parser.jay (member_access): Turn built-in access to types
3666 into a normal simplename
3668 2001-09-27 Ravi Pratap <ravi@ximian.com>

3682 I had introduced long ago (what's new ?).
3684 * expression.cs (UserImplicitCast::CanConvert): Static method to do
3685 the work of all the checking.
3686 (ConvertImplicit): Call CanConvert and only then create object if necessary.
3687 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
3689 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
3690 that is the right way.
3692 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
3693 overloading resolution. Use everywhere instead of cutting and pasting code.
3695 (Binary::ResolveOperator): Use MakeUnionSet.
3697 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
3698 we have to convert to bool types. Not complete yet.

3702 * typemanager.cs (TypeManager::CSharpName): support ushort.
3704 * expression.cs (Expression::TryImplicitIntConversion): Attempts
3705 to provide an expression that performsn an implicit constant int
3706 conversion (section 6.1.6).
3707 (Expression::ConvertImplicitRequired): Reworked to include
3708 implicit constant expression conversions.
3710 (Expression::ConvertNumericExplicit): Finished.
3712 (Invocation::Emit): If InstanceExpression is null, then it means
3713 that we perform a call on this.
3715 2001-09-26 Miguel de Icaza <miguel@ximian.com>
3717 * expression.cs (Unary::Emit): Remove some dead code.
3718 (Probe): Implement Resolve and Emit for `is'.
3719 (Expression::ConvertImplicitRequired): Attempt to do constant
3720 expression conversions here. Maybe should be moved to
3721 ConvertImplicit, but I am not sure.
3722 (Expression::ImplicitLongConstantConversionPossible,
3723 Expression::ImplicitIntConstantConversionPossible): New functions
3724 that tell whether is it possible to apply an implicit constant
3725 expression conversion.

3734 (Parameters::VerifyArgs): Verifies that no two arguments have the
3737 * class.cs (Operator): Update the operator names to reflect the
3738 ones that the spec expects (as we are just stringizing the
3741 * expression.cs (Unary::ResolveOperator): Fix bug: Use
3742 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
3743 previous usage did only work for our methods.
3744 (Expression::ConvertImplicit): Handle decimal implicit numeric
3745 conversions as well.
3746 (Expression::InternalTypeConstructor): Used to invoke constructors
3747 on internal types for default promotions.
3749 (Unary::Emit): Implement special handling for the pre/post
3750 increment/decrement for overloaded operators, as they need to have
3751 the same semantics as the other operators.
3753 (Binary::ResolveOperator): ditto.

3771 * assign.cs (Assign): Make it inherit from ExpressionStatement.
3773 * expression.cs (ExpressionStatement): New base class used for
3774 expressions that can appear in statements, so that we can provide
3775 an alternate path to generate expression that do not leave a value
3778 (Expression::Emit, and all the derivatives): We no longer return
3779 whether a value is left on the stack or not. Every expression
3780 after being emitted leaves a single value on the stack.
3782 * codegen.cs (EmitContext::EmitStatementExpression): Use the
3783 facilties of ExpressionStatement if possible.
3785 * cs-parser.jay: Update statement_expression.

3806 (ConvertImplicit): Do user-defined conversion if it exists.
3808 2001-09-24 Miguel de Icaza <miguel@ximian.com>
3810 * assign.cs: track location.
3811 (Resolve): Use implicit conversions on assignment.

3876 * typemanager.cs: declare and load enum_type, delegate_type and
3879 * expression.cs (Expression::Emit): Now emit returns a value that
3880 tells whether a value is left on the stack or not. This strategy
3881 might be reveted tomorrow with a mechanism that would address
3882 multiple assignments.
3883 (Expression::report118): Utility routine to report mismatches on

3940 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
3941 Use a basename for those routines because .NET does not like paths

4011 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
4012 the last instruction contains a return opcode to avoid generating
4013 the last `ret' instruction (this generates correct code, and it is
4014 nice to pass the peverify output).
4016 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
4017 initializer for static and instance variables.
4018 (Constructor::Emit): Allow initializer to be null in the case of
4019 static constructors. Only emit initializer for instance

4075 (Expression::MemberLookup): Provide a version that allows to
4076 specify the MemberTypes and BindingFlags.

4079 so it was not fetching variable information from outer blocks.
4081 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
4082 Beforefieldinit as it was buggy.
4084 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
4087 * class.cs (Constructor::Emit): Only emit if block is not null.
4088 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
4089 deal with this by semantically definining it as if the user had
4092 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
4093 constructors as we now "emit" them at a higher level.

4197 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
4198 incorrect. IsTopLevel is not used to tell whether an object is
4199 root_types or not (that can be achieved by testing this ==
4200 root_types). But to see if this is a top-level *class* (not
4201 necessarly our "toplevel" container).
4203 2001-09-14 Ravi Pratap <ravi@ximian.com>
4205 * enum.cs (Enum::Define): Modify to call the Lookup method on the
4206 parent instead of a direct call to GetType.
4208 2001-09-14 Ravi Pratap <ravi@ximian.com>
4210 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
4211 Modifiers.TypeAttr. This should just be a call to that method.
4213 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
4214 object so that we can determine if we are top-level or not.
4216 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
4219 * enum.cs (Enum::Define): Ditto.
4221 * modifiers.cs (FieldAttr): Re-write.

4224 (TypeContainer::HaveStaticConstructor): New property to provide access
4225 to precisely that info.
4227 * modifiers.cs (MethodAttr): Re-write.
4228 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
4230 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
4231 of top-level types as claimed.
4233 2001-09-13 Miguel de Icaza <miguel@ximian.com>
4235 * expression.cs (MemberLookup): Fruitless attempt to lookup
4236 constructors. Maybe I need to emit default constructors? That

4239 (Invocation::EmitArguments): new function, shared by the new

4261 objects that we might have around.
4263 (Populate): Only initialize method_builders_to_methods once.
4265 * expression.cs (PropertyExpr): Initialize type from the
4268 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

4273 (Binary::ResolveOperator): Set the return type to boolean for
4274 comparission operators

4281 elsewhere depends on the test to reflect the correct contents.
4283 (Method::) Keep track of parameters, due to System.Reflection holes
4285 (TypeContainer::Populate): Keep track of MethodBuilders to Method
4288 (TypeContainer::FindMembers): Use ArrayList and then copy an array
4289 of the exact size and return that.
4291 (Class::LookupMethodByBuilder): New function that maps
4292 MethodBuilders to its methods. Required to locate the information
4293 on methods because System.Reflection bit us again.
4295 * support.cs: New file, contains an interface ParameterData and
4296 two implementations: ReflectionParameters and InternalParameters
4297 used to access Parameter information. We will need to grow this
4300 * expression.cs (Invocation::GetParameterData): implement a cache
4301 and a wrapper around the ParameterData creation for methods.
4302 (Invocation::OverloadResolve): Use new code.
4304 2001-09-13 Ravi Pratap <ravi@ximian.com>

4358 2001-09-12 Ravi Pratap <ravi@ximian.com>
4360 * class.cs (TypeContainer::FindMembers): Method which does exactly
4361 what Type.FindMembers does, only we don't have to use reflection. No
4364 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
4365 typecontainer objects as we need to get at them.
4366 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

4393 (Event::Define): Ditto.
4394 (Property::Define): Ditto.
4396 2001-09-10 Ravi Pratap <ravi@ximian.com>
4398 * class.cs (TypeContainer::Populate): Now define operators too.
4399 (TypeContainer.Operators): New property to access the list of operators
4401 (Operator.OperatorMethodBuilder): New member to hold the method builder
4402 for the operator we are defining.

4407 * class.cs (Event::Define): Make the prefixes of the accessor methods
4408 addOn_ and removeOn_
4410 * genericparser.cs (GenericParser::error): Overloaded method to handle the case

4412 error reporting should be done through the Report object.
4414 * class.cs (TypeContainer.Indexers): New property to access the list of indexers.
4415 (Populate): Iterate thru the indexers we have and define them too.

4457 (CheckBinaryOperator): Same here.
4459 * rootcontext.cs (LookupType): Add an extra lookup which simply does a lookup
4460 on the name without any prefixes of namespace names etc. This is because we
4461 already might have something already fully qualified like
4462 'System.Console.WriteLine'

4613 will is used during the tree rewriting as we resolve them during
4616 (Expression::MemberLookup): Implements the MemberLookup (7.3) from

4622 a MemberInfo that is one of Eventinfo, FieldINfo, PropertyInfo or

4688 tell whether an identifier represents a namespace.

4733 * class.cs (TypeContainer::Populate): Update to define all enums and events

4740 * class.cs (Property): Revamp to use the convention of making fields readonly.

4789 and re-write the code in the actions to extract the specific and
4790 general catch clauses by being a little smart ;-)
4792 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
4793 Hooray, try and catch statements parse fine !
4795 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
4797 * statement.cs (Block::GetVariableType): Fix logic to extract the type
4798 string from the hashtable of variables.
4800 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did

4802 (catch_clauses): Fixed gross error which made Key and Value of the

4819 implicit_parameters come into picture even for the get accessor in the
4821 (get_accessor_declaration, set_accessor_declaration): Correspondingly modified.
4823 * class.cs (Indexer): New class for indexer declarations.
4824 (TypeContainer::AddIndexer): New method to add an indexer to a type.
4825 (TypeContainer::indexers): New member to hold list of indexers for the
4828 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
4830 * cs-parser.jay (add_accessor_declaration): Implement action.
4831 (remove_accessor_declaration): Implement action.
4832 (event_accessors_declaration): Implement
4833 (variable_declarators): swap statements for first rule - trivial.
4835 * class.cs (Event): New class to hold information about event
4837 (TypeContainer::AddEvent): New method to add an event to a type
4838 (TypeContainer::events): New member to hold list of events.
4840 * cs-parser.jay (event_declaration): Implement actions.
4842 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
4844 * cs-parser.jay (dim_separators): Implement. Make it a string
4845 concatenating all the commas together, just as they appear.
4846 (opt_dim_separators): Modify accordingly
4847 (rank_specifiers): Update accordingly. Basically do the same
4848 thing - instead, collect the brackets here.
4849 (opt_rank_sepcifiers): Modify accordingly.
4850 (array_type): Modify to actually return the complete type string
4851 instead of ignoring the rank_specifiers.
4852 (expression_list): Implement to collect the expressions
4853 (variable_initializer): Implement. We make it a list of expressions
4854 essentially so that we can handle the array_initializer case neatly too.
4855 (variable_initializer_list): Implement.
4856 (array_initializer): Make it a list of variable_initializers
4857 (opt_array_initializer): Modify accordingly.
4859 * expression.cs (New::NType): Add enumeration to help us
4860 keep track of whether we have an object/delegate creation
4861 or an array creation.
4862 (New:NewType, New::Rank, New::Indices, New::Initializers): New
4863 members to hold data about array creation.
4864 (New:New): Modify to update NewType
4865 (New:New): New Overloaded contructor for the array creation
4868 * cs-parser.jay (array_creation_expression): Implement to call
4869 the overloaded New constructor.
4871 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
4873 * class.cs (TypeContainer::Constructors): Return member
4874 constructors instead of returning null.
4876 2001-08-26 Miguel de Icaza <miguel@ximian.com>
4878 * typemanager.cs (InitCoreTypes): Initialize the various core
4879 types after we have populated the type manager with the user
4880 defined types (this distinction will be important later while
4881 compiling corlib.dll)
4883 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
4884 on Expression Classification. Now all expressions have a method
4885 `Resolve' and a method `Emit'.
4887 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
4888 generation from working. Also add some temporary debugging
4891 2001-08-24 Miguel de Icaza <miguel@ximian.com>
4893 * codegen.cs: Lots of code generation pieces. This is only the
4894 beginning, will continue tomorrow with more touches of polish. We
4895 handle the fundamentals of if, while, do, for, return. Others are
4896 trickier and I need to start working on invocations soon.
4898 * gen-treedump.cs: Bug fix, use s.Increment here instead of
4901 * codegen.cs (EmitContext): New struct, used during code
4902 emission to keep a context. Most of the code generation will be
4905 * cs-parser.jay: Add embedded blocks to the list of statements of
4906 this block. So code generation proceeds in a top down fashion.
4908 2001-08-23 Miguel de Icaza <miguel@ximian.com>
4910 * statement.cs: Add support for multiple child blocks.
4912 2001-08-22 Miguel de Icaza <miguel@ximian.com>
4914 * codegen.cs (EmitCode): New function, will emit the code for a
4915 Block of code given a TypeContainer and its ILGenerator.
4917 * statement.cs (Block): Standard public readonly optimization.
4918 (Block::Block constructors): Link children.
4919 (Block::Child): Child Linker.
4920 (Block::EmitVariables): Emits IL variable declarations.
4922 * class.cs: Drop support for MethodGroups here, delay until
4924 (Method::): Applied the same simplification that I did before, and
4925 move from Properties to public readonly fields.
4926 (Method::ParameterTypes): Returns the parameter types for the
4927 function, and implements a cache that will be useful later when I
4928 do error checking and the semantic analysis on the methods is
4930 (Constructor::GetCallingConvention): Renamed from CallingConvetion
4931 and made a method, optional argument tells whether this is a class
4932 or a structure to apply the `has-this' bit.
4933 (Method::GetCallingConvention): Implement, returns the calling
4935 (Method::Define): Defines the type, a second pass is performed
4936 later to populate the methods.
4938 (Constructor::ParameterTypes): implement a cache similar to the
4939 one on Method::ParameterTypes, useful later when we do semantic
4942 (TypeContainer::EmitMethod): New method. Emits methods.
4944 * expression.cs: Removed MethodGroup class from here.
4946 * parameter.cs (Parameters::GetCallingConvention): new method.
4948 2001-08-21 Miguel de Icaza <miguel@ximian.com>
4950 * class.cs (TypeContainer::Populate): Drop RootContext from the
4953 (Constructor::CallingConvention): Returns the calling convention.
4954 (Constructor::ParameterTypes): Returns the constructor parameter
4957 (TypeContainer::AddConstructor): Keep track of default constructor
4958 and the default static constructor.
4960 (Constructor::) Another class that starts using `public readonly'
4961 instead of properties.
4963 (Constructor::IsDefault): Whether this is a default constructor.
4965 (Field::) use readonly public fields instead of properties also.
4967 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
4968 track of static constructors; If none is used, turn on
4969 BeforeFieldInit in the TypeAttributes.
4971 * cs-parser.jay (opt_argument_list): now the return can be null
4972 for the cases where there are no arguments.
4974 (constructor_declarator): If there is no implicit `base' or
4975 `this', then invoke the default parent constructor.
4977 * modifiers.cs (MethodAttr): New static function maps a set of
4978 modifiers flags into a MethodAttributes enum
4979 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
4980 MethodAttr, TypeAttr to represent the various mappings where the
4982 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
4984 2001-08-19 Miguel de Icaza <miguel@ximian.com>
4986 * parameter.cs (GetParameterInfo): Fix bug where there would be no
4989 * interface.cs (PopulateIndexer): Implemented the code generator
4990 for interface indexers.
4992 2001-08-17 Miguel de Icaza <miguel@ximian.com>
4994 * interface.cs (InterfaceMemberBase): Now we track the new status
4997 (PopulateProperty): Implement property population. Woohoo! Got
4998 Methods and Properties going today.
5000 Removed all the properties for interfaces, and replaced them with
5001 `public readonly' fields.
5003 2001-08-16 Miguel de Icaza <miguel@ximian.com>
5005 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
5006 initialize their hashtables/arraylists only when they are needed
5007 instead of doing this always.
5009 * parameter.cs: Handle refs and out parameters.
5011 * cs-parser.jay: Use an ArrayList to construct the arguments
5012 instead of the ParameterCollection, and then cast that to a
5015 * parameter.cs: Drop the use of ParameterCollection and use
5016 instead arrays of Parameters.
5018 (GetParameterInfo): Use the Type, not the Name when resolving
5021 2001-08-13 Miguel de Icaza <miguel@ximian.com>
5023 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
5024 and instead use public readonly fields.
5026 * class.cs: Put back walking code for type containers.
5028 2001-08-11 Miguel de Icaza <miguel@ximian.com>
5030 * class.cs (MakeConstant): Code to define constants.
5032 * rootcontext.cs (LookupType): New function. Used to locate types
5035 2001-08-08 Miguel de Icaza <miguel@ximian.com>
5037 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
5038 this System.Reflection code is. Kudos to Microsoft
5040 * typemanager.cs: Implement a type cache and avoid loading all
5041 types at boot time. Wrap in LookupType the internals. This made
5042 the compiler so much faster. Wow. I rule!
5044 * driver.cs: Make sure we always load mscorlib first (for
5045 debugging purposes, nothing really important).
5047 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
5048 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
5050 * rootcontext.cs: Lookup types on their namespace; Lookup types
5051 on namespaces that have been imported using the `using' keyword.
5053 * class.cs (TypeContainer::TypeAttr): Virtualize.
5054 (Class::TypeAttr): Return attributes suitable for this bad boy.
5055 (Struct::TypeAttr): ditto.
5056 Handle nested classes.
5057 (TypeContainer::) Remove all the type visiting code, it is now
5058 replaced with the rootcontext.cs code
5060 * rootcontext.cs (GetClassBases): Added support for structs.
5062 2001-08-06 Miguel de Icaza <miguel@ximian.com>
5064 * interface.cs, statement.cs, class.cs, parameter.cs,
5065 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
5066 Drop use of TypeRefs, and use strings instead.
5068 2001-08-04 Miguel de Icaza <miguel@ximian.com>
5072 * class.cs (Struct::Struct): set the SEALED flags after
5073 checking the modifiers.
5074 (TypeContainer::TypeAttr): new property, returns the
5075 TypeAttributes for a class.
5077 * cs-parser.jay (type_list): Oops, list production was creating a
5078 new list of base types.
5080 * rootcontext.cs (StdLib): New property.
5081 (GetInterfaceTypeByName): returns an interface by type name, and
5082 encapsulates error handling here.
5083 (GetInterfaces): simplified.
5084 (ResolveTree): Encapsulated all the tree resolution here.
5085 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
5088 * driver.cs: Add support for --nostdlib, to avoid loading the
5090 (Main): Do not put tree resolution here.
5092 * rootcontext.cs: Beginning of the class resolution.
5094 2001-08-03 Miguel de Icaza <miguel@ximian.com>
5096 * rootcontext.cs: Provide better error reporting.
5098 * cs-parser.jay (interface_base): set our $$ to be interfaces.
5100 * rootcontext.cs (CreateInterface): Handle the case where there
5101 are no parent interfaces.
5103 (CloseTypes): Routine to flush types at the end.
5104 (CreateInterface): Track types.
5105 (GetInterfaces): Returns an array of Types from the list of
5108 * typemanager.c (AddUserType): Mechanism to track user types (puts
5109 the type on the global type hash, and allows us to close it at the
5112 2001-08-02 Miguel de Icaza <miguel@ximian.com>
5114 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
5115 RecordInterface instead.
5117 * cs-parser.jay: Updated to reflect changes above.
5119 * decl.cs (Definition): Keep track of the TypeBuilder type that
5120 represents this type here. Not sure we will use it in the long
5121 run, but wont hurt for now.
5123 * driver.cs: Smaller changes to accomodate the new code.
5125 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
5128 * rootcontext.cs (CreateInterface): New method, used to create
5129 the System.TypeBuilder type for interfaces.
5130 (ResolveInterfaces): new entry point to resolve the interface
5132 (CodeGen): Property, used to keep track of the code generator.
5134 2001-07-26 Miguel de Icaza <miguel@ximian.com>
5136 * cs-parser.jay: Add a second production for delegate_declaration
5139 (enum_body): Put an opt_comma here instead of putting it on
5140 enum_body or enum_member_declarations so we can handle trailing
5141 commas on enumeration members. Gets rid of a shift/reduce.
5143 (type_list): Need a COMMA in the middle.
5145 (indexer_declaration): Tell tokenizer to recognize get/set
5147 * Remove old targets.
5149 * Re-add the parser target.
5151 2001-07-13 Simon Cozens <simon@simon-cozens.org>
5153 * cs-parser.jay: Add precendence rules for a number of operators
5154 ot reduce the number of shift/reduce conflicts in the grammar.
5156 2001-07-17 Miguel de Icaza <miguel@ximian.com>
5158 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
5161 Get rid of old crufty code.
5163 * rootcontext.cs: Use this to keep track of the parsed
5164 representation and the defined types available to the program.
5166 * gen-treedump.cs: adjust for new convention.
5168 * type.cs: Split out the type manager, and the assembly builder
5171 * typemanager.cs: the type manager will live here now.
5173 * cil-codegen.cs: And the code generator here.
5175 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
5177 * makefile: Fixed up for easy making.
5179 2001-07-13 Simon Cozens <simon@simon-cozens.org>
5181 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
5184 (unary_expression): Expand pre_increment_expression and
5185 post_decrement_expression to reduce a shift/reduce.
5187 2001-07-11 Simon Cozens
5189 * cs-tokenizer.cs: Hex numbers should begin with a 0.
5191 Improve allow_keyword_as_indent name.
5193 2001-06-19 Miguel de Icaza <miguel@ximian.com>
5195 * Adjustments for Beta2.
5197 2001-06-13 Miguel de Icaza <miguel@ximian.com>
5199 * decl.cs: Added `Define' abstract method.
5200 (InTransit): new property, used to catch recursive definitions.
5202 * interface.cs: Implement `Define'.
5204 * modifiers.cs: Map Modifiers.constants to
5205 System.Reflection.TypeAttribute flags.
5207 * class.cs: Keep track of types and user-defined types.
5208 (BuilderInit): New method for creating an assembly
5209 (ResolveType): New function to launch the resolution process, only
5210 used by interfaces for now.
5212 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
5213 that are inserted into the name space.
5215 2001-06-08 Miguel de Icaza <miguel@ximian.com>
5217 * ARGH. I have screwed up my tree so many times due to the use of
5218 rsync rather than using CVS. Going to fix this at once.
5220 * driver.cs: Objetify driver. Load assemblies, use assemblies to
5223 2001-06-07 Miguel de Icaza <miguel@ximian.com>
5225 * Experiment successful: Use System.Type rather that our own
5228 2001-05-25 Miguel de Icaza <miguel@ximian.com>
5230 * cs-parser.jay: Removed nsAliases from here.
5232 Use new namespaces, handle `using XXX;'
5234 * namespace.cs: Reimplemented namespace handling, use a recursive
5235 definition of the class. Now we can keep track of using clauses
5236 and catch invalid using clauses.
5238 2001-05-24 Miguel de Icaza <miguel@ximian.com>
5240 * gen-treedump.cs: Adapted for all the renaming.
5242 * expression.cs (Expression): this class now has a Type property
5243 which returns an expression Type.
5245 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
5246 `Type', as this has a different meaning now in the base
5248 2001-05-22 Miguel de Icaza <miguel@ximian.com>
5250 * interface.cs, class.cs: Removed from all the sources the
5251 references to signature computation, as we can not do method
5252 signature computation during the parsing time, as we are not
5253 trying to solve at that point distinguishing:
5257 void a (NS.Blah x) {}
5260 Which depending on the context might be valid or not, as we do not
5261 know if Blah is the same thing as NS.Blah at that point.
5263 * Redid everything so the code uses TypeRefs now instead of
5264 Types. TypeRefs are just temporary type placeholders, that need
5265 to be resolved. They initially have a pointer to a string and the
5266 current scope in which they are used. This is used later by the
5267 compiler to resolve the reference to an actual Type.
5269 * DeclSpace is no longer a CIR.Type, and neither are
5270 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
5271 are all DeclSpaces, but no Types.
5273 * type.cs (TypeRefManager): This implements the TypeRef manager,
5274 which keeps track of all the types that need to be resolved after
5275 the parsing has finished.
5277 2001-05-13 Miguel de Icaza <miguel@ximian.com>
5279 * ARGH. We are going to have to store `foreach' as a class rather
5280 than resolving it, as we need to verify error 1579 after name
5281 resolution. *OR* we could keep a flag that says `This request to
5282 IEnumerator comes from a foreach statement' which we can then use
5283 to generate the error.
5285 2001-05-10 Miguel de Icaza <miguel@ximian.com>
5287 * class.cs (TypeContainer.AddMethod): we now add methods to the
5288 MethodGroup instead of the method hashtable.
5290 * expression.cs: Add MethodGroup abstraction, which gets us one
5291 step closer to the specification in the way we handle method
5294 * cs-parser.jay (primary_expression): qualified_identifier now
5295 tried to match up an identifier to a local variable reference or
5296 to a parameter reference.
5298 current_local_parameters is now a parser global variable that
5299 points to the current parameters for the block, used during name
5302 (property_declaration): Now creates an implicit `value' argument to
5305 2001-05-09 Miguel de Icaza <miguel@ximian.com>
5307 * parameter.cs: Do not use `param' arguments as part of the
5308 signature, per the spec.
5310 2001-05-08 Miguel de Icaza <miguel@ximian.com>
5312 * decl.cs: Base class for classes, structs and interfaces. This
5313 is the "Declaration Space"
5315 * cs-parser.jay: Use CheckDef for checking declaration errors
5316 instead of having one on each function.
5318 * class.cs: Factor out some code for handling error handling in
5319 accordance to the "Declarations" section in the "Basic Concepts"
5320 chapter in the ECMA C# spec.
5322 * interface.cs: Make all interface member classes derive from
5323 InterfaceMemberBase.
5325 2001-05-07 Miguel de Icaza <miguel@ximian.com>
5327 * Many things: all interfaces are parsed and generated in
5328 gen-treedump. Support for member variables, constructors,
5329 destructors, properties, constants is there.
5331 Beginning of the IL backend, but very little done, just there for
5334 2001-04-29 Miguel de Icaza <miguel@ximian.com>
5336 * cs-parser.jay: Fix labeled statement.
5338 * cs-tokenizer.cs (escape): Escape " and ' always.
5339 ref_line, ref_name: keep track of the line/filename as instructed
5340 by #line by the compiler.
5343 2001-04-27 Miguel de Icaza <miguel@ximian.com>
5345 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
5346 to match the values in System.CodeDOM.
5348 Divid renamed to Divide.
5350 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
5352 (Statements.set): remove.
5354 * System.CodeDOM/CodeCatchClause.cs: always have a valid
5357 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
5358 falseStatements always have valid values.
5360 * cs-parser.jay: Use System.CodeDOM now.
