3 * support.cs (InternalParameters.ParameterModifier): handle null
5 (InternalParameters.ParameterType): ditto.
7 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
8 duplicating the name of the variable parameter.
9 (GetParameterByName): Fix bug where we were not looking up array
10 paramters if they were the only present (thanks Paolo!).
11 (GetParameterInfo): We only have an empty set of types if both
12 fixed and array are set to null.
13 (GetParameterInfo-idx): Handle FixedParameter == null
15 * cs-parser.jay: Handle the case where there is no catch
16 statements (missing null test).
18 2002-02-22 Miguel de Icaza <miguel@ximian.com>
20 * driver.cs (MainDriver): Be conservative on our command line
23 Catch DirectoryNotFoundException when calling GetFiles.
25 (SplitPathAndPattern): Used to split the input specification into
26 a path and a pattern that we can feed to Directory.GetFiles.
28 2002-02-21 Miguel de Icaza <miguel@ximian.com>
30 * statement.cs (Fixed): Implement the last case of the Fixed
31 statement (string handling).
33 * expression.cs (StringPtr): New class used to return a char * to
34 a string; Used by the Fixed statement.
36 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
38 * expression.cs (Binary.ResolveOperator): Remove redundant
39 MemberLookup pn parent type.
40 Optimize union call, we do not need a union if the types are the same.
41 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
44 Specialize the use of MemberLookup everywhere, instead of using
47 (StackAlloc): Implement stackalloc keyword.
49 * cs-parser.jay: Add rule to parse stackalloc.
51 * driver.cs: Handle /h, /help, /?
53 * expression.cs (MakeByteBlob): Removed the hacks we had in place
54 before we supported unsafe code.

63 Handle pointer comparission.
64 (ArrayPtr): Utility expression class that is used to take the
67 (ElementAccess): Implement array access for pointers
69 * statement.cs (Fixed): Implement fixed statement for arrays, we
70 are missing one more case before we are done.
72 * expression.cs (Indirection): Implement EmitAssign and set the
73 ExprClass to Variable. This allows pointer dereferences to be
74 treated as variables, and to have values assigned to them.
76 * ecore.cs (Expression.StoreFromPtr): New utility function to
77 store values dereferencing.
79 2002-02-20 Ravi Pratap <ravi@ximian.com>
81 * expression.cs (Binary.ResolveOperator): Ensure that we are
82 not trying to operate on a void type - this fixes the reported

90 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
92 * typemanager.cs (unverifiable_code_type): Corresponds to
93 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
94 which have unsafe code in them.
96 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
99 2002-02-19 Miguel de Icaza <miguel@ximian.com>
101 * cs-tokenizer.cs: Add support for @"litreal strings"
103 Make tokenizer accept pre-processor directives
104 on any column (remove the old C-like limitation).

107 (AddGlobalAttributes): Used to keep track of assembly attributes.
109 * attribute.cs (ApplyAttributes): Support AssemblyAttributes.

121 * cs-parser.jay (fixed_statement): reference the right statement.
123 * statement.cs (Fixed.Emit): Finish implementing the fixed
124 statement for the &x case.
126 2002-02-14 Miguel de Icaza <miguel@ximian.com>
128 * class.cs (Property.Define, Method.Define): Remove newslot when
131 * modifiers.cs: My use of NewSlot when `Abstract' was set was
132 wrong. NewSlot should only be used if the `new' keyword is present.
134 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
135 locating our system dir. Sorry about this.
137 2002-02-13 Miguel de Icaza <miguel@ximian.com>
139 * driver.cs (GetSystemDir): Compute correctly the location of our
140 system assemblies. I was using the compiler directory instead of
141 the library directory.
143 2002-02-13 Ravi Pratap <ravi@ximian.com>
145 * expression.cs (BetterFunction): Put back in what Miguel commented out
146 since it is the correct fix. The problem is elsewhere ;-)
148 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
149 parameters of the parms method are themselves compatible or not !
151 (StandardConversionExists): Fix very dangerous bug where we were forgetting
152 to check that a class implements an interface before saying that an implicit
153 conversion was allowed. Use ImplementsInterface to do the checking.
155 2002-02-13 Miguel de Icaza <miguel@ximian.com>
157 * class.cs (Method.Define): Track whether we are an explicit
158 implementation or not. And only call DefineMethodOverride if we
159 are an explicit implementation.
161 (Property.DefineMethod): Ditto.
163 2002-02-11 Ravi Pratap <ravi@ximian.com>
165 * expression.cs (BetterFunction): Catch hideous bug which was
166 preventing us from detecting ambiguous calls due to implicit casts i.e
169 2002-01-29 Miguel de Icaza <miguel@ximian.com>
171 * support.cs (Pair): Remove un-needed method. I figured why I was
172 getting the error in cs-parser.jay, the variable in a foreach loop
173 is readonly, and the compiler does not really treat this as a variable.
175 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
176 instead of EQUALS in grammar.
178 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
180 * expression.cs (Unary.DoResolve): Check whether the argument is
183 2002-01-28 Miguel de Icaza <miguel@ximian.com>
185 * support.cs: Api for Pair to set a value. Despite the fact that
186 the variables are public the MS C# compiler refuses to compile
187 code that accesses the field if the variable is part of a foreach
190 * statement.cs (Fixed): Begin implementation of the fixed
193 (Block.AddVariable): Return the VariableInfo on success and null
194 on failure instead of true/false.
196 * cs-parser.jay (foreach): Catch errors on variables already
197 defined (we were ignoring this value before) and properly unwind
200 (fixed_statement): grammar for the fixed statement.
202 2002-01-25 Miguel de Icaza <miguel@ximian.com>
204 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
205 pointer types to be incretemented.
209 * cs-parser.jay (pointer_member_access): Implement
210 expr->IDENTIFIER production.
212 * expression.cs (IndexerAccess.DoResolve, ArrayAccess.DoResolve,
213 MemberAccess.DoResolve, Invocation.DoResolve): Check for pointers
216 (Unary): Implement indirection.
218 * ecore.cs (Expression.UnsafeError): Reports error 214 (pointer
219 use in non-unsafe context).
221 (SimpleName.DoResolve): Check for pointers in field access on safe
224 (Expression.LoadFromPtr): Factor the load-indirect code in this

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

280 2002-01-21 Miguel de Icaza <miguel@ximian.com>
282 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
283 need to make a copy of the variable to generate verifiable code.
285 2002-01-19 Miguel de Icaza <miguel@ximian.com>
287 * driver.cs: Compute dynamically the system directory.
289 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
290 Slower, but more generally useful. Used by the abstract
291 registering implementation.
293 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
294 the rules for the special rule on Type/instances. First check if
295 we have the same name, and if so, try that special static path
296 rather than the instance path.
298 2002-01-18 Miguel de Icaza <miguel@ximian.com>
300 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
303 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
304 Enum, ValueType, Delegate or Array for non-corlib compiles.
306 * cs-tokenizer.cs: Catch long identifiers (645)
308 * typemanager.cs (IndexerPropetyName): Ravi never tested this
311 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
312 fix, we were returning too early, so we were not registering
313 pending methods from abstract classes.
315 Do not register pending methods if the class is abstract.
317 * expression.cs (Conditional.DoResolve): Report circular implicit
318 conversions when we neecd to compute it for conditional
321 (Is.DoResolve): If the expression is always of the provided type,
322 flag warning 183. If the expression can not ever be of the
323 provided type flag warning 184.
325 * class.cs: Catch 169 as well.
327 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
330 2002-01-18 Nick Drochak <ndrochak@gol.com>
332 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.
334 2002-01-17 Miguel de Icaza <miguel@ximian.com>
336 * interface.cs: (PopulateMethod): Check for pointers being defined
337 only if the unsafe context is active.
338 (PopulateProperty): ditto.
339 (PopulateIndexer): ditto.
341 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
342 specified. If pointers are present, make sure that they are
343 present in an unsafe context.
344 (Constructor, Constructor.Define): ditto.
345 (Field, Field.Define): ditto.
346 (Property, Property.Define): ditto.
347 (Event, Event.Define): ditto.
349 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
350 hashtable if there are classes or structs defined.
352 * expression.cs (LocalVariableReference.DoResolve): Simplify this
353 code, as the constant resolution moved.
355 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
356 the metadata, so we can flag error 133.
358 * decl.cs (MemberCore.UnsafeOK): New function to test that a
359 pointer is being declared in an unsafe context.
361 2002-01-16 Miguel de Icaza <miguel@ximian.com>
363 * modifiers.cs (Modifiers.Check): Require a Location argument.
364 Report error 227 for Unsafe use.
366 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
368 * statement.cs (For.Emit): If the test is null, then report that
369 we do `return', as we wont reach anything afterwards.
371 (Switch.SwitchGoverningType): Track the expression that matched
374 * driver.cs: Allow negative numbers as an error code to flag.
376 * cs-parser.jay: Handle 1551.
378 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
380 2002-01-15 Miguel de Icaza <miguel@ximian.com>
382 * cs-parser.jay: Report 1518 (type declaration can only contain
383 class, struct, interface, enum or delegate)
385 (switch_label): Report 1523 (keywords `case' or `default' must
388 (opt_switch_sections): Report 1522 (empty switch)
390 * driver.cs: Report 1515 (response file specified multiple times)
391 Report 1516 (Source file specified multiple times).
393 * expression.cs (Argument.Resolve): Signal 1510

396 access not allowed in static code)
398 2002-01-11 Ravi Pratap <ravi@ximian.com>
400 * typemanager.cs (IsPointerType): Utility method which we are going
403 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
404 the object type, so we take care of that.
406 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
408 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
409 added to non-params parameters :-)
411 * typemanager.cs (CSharpName): Include 'void' type too.
413 (void_ptr_type): Include in the set of core types.
415 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
418 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
421 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
422 completely forgotten about it.
424 2002-01-10 Ravi Pratap <ravi@ximian.com>
426 * cs-parser.jay (pointer_type): Add. This begins our implementation
427 of parsing rules for unsafe code.
429 (unsafe_statement): Implement.
431 (embedded_statement): Modify to include the above.
433 * statement.cs (Unsafe): Implement new class for unsafe blocks.
435 * codegen.cs (EmitContext.InUnsafe): Add. This determines
436 if the current context is an unsafe one.
438 * cs-parser.jay (local_variable_pointer_type): Since local variable types
439 are handled differently, we need separate rules for them.
441 (local_variable_declaration): Update to use local_variable_pointer_type
442 to allow variable declarations of unmanaged pointer types.
444 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
447 * ../errors/cs0214.cs : Add.
449 2002-01-16 Nick Drochak <ndrochak@gol.com>
451 * makefile: remove 'response' file when cleaning.
453 2002-01-15 Miguel de Icaza <miguel@ximian.com>
455 * cs-parser.jay: Report 1524.
457 2002-01-14 Miguel de Icaza <miguel@ximian.com>
459 * typemanager.cs (RegisterMethod): drop checking if we have
460 registered this from here
462 2002-01-12 Miguel de Icaza <miguel@ximian.com>
464 * class.cs (Method.EmitDestructor): Implement calling our base
467 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
470 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
471 this routine and will wrap the call in a try/catch block. Deal
474 2002-01-11 Miguel de Icaza <miguel@ximian.com>
476 * ecore.cs (Expression.MemberLookup): instead of taking a
477 parameter `same_type' that was used to tell whether we could
478 access private members we compute our containing type from the
481 (FieldExpr): Added partial support for volatile fields. This does
482 not work for volatile fields exposed from assemblies, as I can not
483 figure out how to extract the modreq from it.
485 Updated all the source files to use this.
487 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
488 because it is referenced by MemberLookup very often.
490 2002-01-09 Ravi Pratap <ravi@ximian.com>
492 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
493 TypeBuilder.GetCustomAttributes to retrieve what we need.
495 Get rid of redundant default_member_attr_type as this is the same as
496 default_member_type which already exists.
498 * interface.cs, attribute.cs : Update accordingly.
500 2002-01-08 Miguel de Icaza <miguel@ximian.com>
502 * typemanager.cs: Enable IndexerPropertyName again. It does not
503 work for TYpeBuilders though. Ravi, can you please fix this?
505 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
507 * expression.cs (Argument.Emit): Handle the case of ref objects
508 being passed to ref functions;
510 (ParameterReference.EmitLoad): Loads the content of the pointer
511 without dereferencing.
513 2002-01-07 Miguel de Icaza <miguel@ximian.com>
515 * cs-tokenizer.cs: Implemented the pre-processing expressions.
517 2002-01-08 Ravi Pratap <ravi@ximian.com>
519 * class.cs (Indexer.DefineMethod): Incorporate the interface
520 type in the name of the method if we are doing explicit interface
523 * expression.cs (ConversionExists): Remove as it is completely obsolete.
525 (BetterConversion): Fix extremely trivial bug where we were referring to
526 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
529 * ../errors/bug16.cs : Add although we have fixed it.
531 2002-01-07 Miguel de Icaza <miguel@ximian.com>
533 * expression.cs (BaseIndexer): Begin implementation.
535 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
537 * cs-parser.jay (indexer_declarator): Use qualified_identifier
538 production directly to remove a shift/reduce, and implement
539 explicit interface implementation.
541 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
542 after a floating point suffix.
544 * expression.cs (DoNumericPromotions): Improved the conversion for
545 uint/uint. If we have a constant, we avoid doing a typecast to a
548 * class.cs (Indexer): Implement explicit interface implementation
551 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
553 * class.cs: make the default instance constructor public and hidebysig.
555 2001-01-03 Ravi Pratap <ravi@ximian.com>
557 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
558 so we can call it from elsewhere.
560 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
561 we emit it internally if the class has a defined indexer; otherwise the user
562 emits it by decorating the class definition with the DefaultMemberAttribute.
564 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
565 attribute is not used on a type which defines an indexer.
567 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
568 character when we skip whitespace.
570 * ../errors/cs0646.cs : Add.
572 2002-01-03 Miguel de Icaza <miguel@ximian.com>
574 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
577 * makefile: Add practical target `mcs3.exe' which builds the third
580 * expression.cs (New): Fix structures constructor calling.
582 * class.cs (Property, Method, Indexer): Emit Final flag on the
583 method if we are an interface implementation and we are not
586 * ecore.cs (PropertyExpr): New public field `IsBase', tells
587 whether this property is referencing a `base' method.
589 * expression.cs (Invocation.EmitCall): take an extra argument:
590 is_base, this is used to determine whether the `call' or
591 `callvirt' opcode should be used.
594 * delegate.cs: update EmitCall.
596 * class.cs (Method.Define): Set NewSlot for the cases where we are
597 not implementing an interface method.
599 (Property.Define): ditto.
601 2002-01-02 Miguel de Icaza <miguel@ximian.com>
603 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
604 'r'. Allows mcs to parse itself fully.
606 2002-01-02 Ravi Pratap <ravi@ximian.com>
608 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
609 of the number of initializers that require the InitializeArray method.
611 (CheckIndices): Store the Expression in all cases - not the plain value. Also
612 update the above field where necessary.
614 (MakeByteBlob): Update accordingly.
616 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
619 (EmitDynamicInitializers): Update in accordance with the new optimization.
621 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
624 * cs-parser.jay : Fix some glaring errors I introduced.
626 2002-01-01 Ravi Pratap <ravi@ximian.com>
628 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
629 so that we can check for name clashes there too.
631 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
632 for interface indexers.
634 * interfaces.cs (Define): Emit the default member attribute.
636 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
637 variable was being referred to while setting the value ;-)
639 2002-01-01 Miguel de Icaza <miguel@ximian.com>
641 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
642 byte-by-byte information when we know the data is zero.
644 Make the block always a multiple of 4, because
645 DefineInitializedData has a bug.
647 * assign.cs: Fix, we should assign from the temporary, not from
650 * expression.cs (MakeByteBlob): Fix my incorrect code.
652 2001-12-31 Miguel de Icaza <miguel@ximian.com>
654 * typemanager.cs (EnumToUnderlying): This function is used to get
655 the underlying type from an enumeration, because it does not
658 * constant.cs: Use the I4_S form for values between -128 and 127.
660 * statement.cs (Block.LookupLabel): Looks up a label.
661 (Block): Drop support for labeled blocks.
663 (LabeledStatement): New kind of statement that represents a label
666 (Goto): Finally implement this bad boy.
668 * cs-parser.jay: Update to reflect new mechanism to implement
671 2001-12-30 Miguel de Icaza <miguel@ximian.com>
673 * codegen.cs (EmitContext.This): a codegen property that keeps the
674 a single instance of this instead of creating many different this
677 * delegate.cs (Delegate.DoResolve): Update to use the property;
679 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
681 * expression.cs (BaseAccess.DoResolve): Ditto.
683 2001-12-29 Ravi Pratap <ravi@ximian.com>
685 * typemanager.cs (methodimpl_attr_type): Add to hold the type
686 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
688 (InitCoreTypes): Update accordingly.
690 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
691 so we can quickly store the state.
693 (ApplyAttributes): Set the correct implementation flags
694 for InternalCall methods.
696 2001-12-29 Miguel de Icaza <miguel@ximian.com>
698 * expression.cs (EmitCall): if a method is not virtual, then do
699 not use callvirt on it.
701 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
702 user defined stuff) requires the use of stobj, which takes an
703 address on the stack instead of an array and an index. So emit
704 the Ldelema operation for it.
706 (EmitStoreOpcode): Use stobj for valuetypes.
708 (UnaryMutator.EmitCode): Use the right 1 value depending on
709 whether we are dealing with int64/uint64, float or doubles.
711 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
712 constructors that I implemented last night.
714 (Constructor.IsDefault): Fix to work properly for static
717 * cs-parser.jay (CheckDef): report method signature errors.
718 Update error number 103 to be 132.
720 * decl.cs: New AdditionResult enumeration value: MethodExists.
721 Although we do this check for methods later on in the semantic
722 analysis, catching repeated default constructors is so easy that
725 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
728 (ParameterReference.EmitAssign, Emit): handle
731 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
732 (ArrayAccess.EmitStoreOpcode): ditto.
734 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
736 * expression.cs (MakeByteBlob): Complete all the missing types
737 (uint, short, ushort, byte, sbyte)
739 * class.cs: Only init instance field initializers on instance
742 Rename `constructors' to instance_constructors.
744 (TypeContainer.AddConstructor): Only add constructors to the list
747 Make sure that we handle default_static_constructor independently
748 everywhere where we handle instance_constructors
750 2001-12-28 Miguel de Icaza <miguel@ximian.com>
752 * class.cs: Do not lookup or create a base initializer for a
755 (ConstructorInitializer.Resolve): use the proper type to lookup
758 * cs-parser.jay: Report error 1585 (modifiers between type and name).
760 * enum.cs, interface.cs: Remove CloseType, this is taken care by
763 * decl.cs: CloseType is now an virtual method, the default
764 implementation just closes this type.
766 2001-12-28 Ravi Pratap <ravi@ximian.com>
768 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
769 to PreserveSig by default. Also emit HideBySig on such methods.
771 Basically, set the defaults to standard values.
773 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
774 argument, if candidate is better, it can't be worse than the best !
776 (Invocation): Re-write bits to differentiate between methods being
777 applicable in their expanded form and their normal form - for params
780 Get rid of use_standard everywhere as only standard conversions are allowed
781 in overload resolution.
783 More spec conformance.
785 2001-12-27 Miguel de Icaza <miguel@ximian.com>
787 * driver.cs: Add --timestamp, to see where the compiler spends
790 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
791 `this' in static code.
793 (SimpleName.DoResolve): Implement in terms of a helper function
794 that allows static-references to be passed upstream to
797 (Expression.ResolveWithSimpleName): Resolve specially simple
798 names when called by MemberAccess to implement the special
801 (Expression.ImplicitReferenceConversion): Handle conversions from
802 Null to reference types before others, as Null's type is
805 * expression.cs (Invocation.EmitCall): Handle the special case of
806 calling methods declared on a reference type from a ValueType
807 (Base classes System.Object and System.Enum)
809 (MemberAccess.Resolve): Only perform lookups on Enumerations if
810 the left hand side is a TypeExpr, not on every enumeration.
812 (Binary.Resolve): If types are reference types, then do a cast to
813 object on operators != and == of both arguments.
815 * typemanager.cs (FindMembers): Extract instance and static
816 members if requested.
818 * interface.cs (PopulateProperty): Use void_type instead of null
819 as the return type for the setter method.
821 (PopulateIndexer): ditto.
823 2001-12-27 Ravi Pratap <ravi@ximian.com>
825 * support.cs (ReflectionParameters): Fix minor bug where we
826 were examining the wrong parameter for the ParamArray attribute.
828 Cope with requests for the type of the parameter at position
829 greater than the params parameter's. We now return the element
830 type of the params array as that makes more sense.
832 * expression.cs (Invocation.IsParamsMethodApplicable): Update
833 accordingly as we no longer have to extract the element type
836 (Invocation.OverloadResolve): Update.
838 2001-12-27 Miguel de Icaza <miguel@ximian.com>
840 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
841 against IEnumerator, test whether the return value is a descendant
842 of the IEnumerator interface.
844 * class.cs (Indexer.Define): Use an auxiliary method to implement
845 the other bits of the method definition. Begin support for
846 explicit interface implementation.
848 (Property.DefineMethod): Use TypeManager.void_type instead of null
849 for an empty return value.
851 2001-12-26 Miguel de Icaza <miguel@ximian.com>
853 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
854 dealing with a FieldExpr which is composed of a FieldBuilder, in
855 the code path we did extract the constant, but we should have
856 obtained the underlying value to be able to cast it (otherwise we
857 end up in an infinite loop, this is what Ravi was running into).
859 (ArrayCreation.UpdateIndices): Arrays might be empty.
861 (MemberAccess.ResolveMemberAccess): Add support for section
862 14.5.4.1 that deals with the special case of E.I when E is a type
863 and something else, that I can be a reference to a static member.
865 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
866 handle a particular array type to create byte blobs, it is just
867 something we dont generate byteblobs for.
869 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
872 * location.cs (Push): remove the key from the hashtable that we
873 are about to add. This happens for empty files.
875 * driver.cs: Dispose files after we have parsed them.
877 (tokenize): new function that only runs the tokenizer on its
878 input, for speed testing.
880 2001-12-26 Ravi Pratap <ravi@ximian.com>
882 * class.cs (Event.Define): Define the private field only if there
883 are no accessors defined.
885 * expression.cs (ResolveMemberAccess): If there is no associated
886 field with the event, that means we have an event defined with its
887 own accessors and we should flag error cs0070 since transforming
888 ourselves into a field is not valid in that case.
890 * ecore.cs (SimpleName.DoResolve): Same as above.
892 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
893 and charset to sane values.
895 2001-12-25 Ravi Pratap <ravi@ximian.com>
897 * assign.cs (DoResolve): Perform check on events only if they
898 are being accessed outside the declaring type.
900 * cs-parser.jay (event_declarations): Update rules to correctly
901 set the type of the implicit parameter etc.
903 (add_accessor, remove_accessor): Set current local parameters.
905 * expression.cs (Binary): For delegate addition and subtraction,
906 cast the return value from the method into the appropriate delegate
909 2001-12-24 Ravi Pratap <ravi@ximian.com>
911 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
912 of these as the workaround is unnecessary.
914 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
915 delegate data - none of that is needed at all.
917 Re-write bits to extract the instance expression and the delegate method
920 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
923 * attribute.cs (ApplyAttributes): New method to take care of common tasks
924 of attaching attributes instead of duplicating code everywhere.
926 * everywhere : Update code to do attribute emission using the above method.
928 2001-12-23 Miguel de Icaza <miguel@ximian.com>
930 * expression.cs (IsParamsMethodApplicable): if there are not
931 parameters, return immediately.
933 * ecore.cs: The 0 literal can be implicity converted to an enum
936 (SimpleName.DoResolve): First lookup the type, then lookup the
939 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
940 want to get its address. If the InstanceExpression is not
941 addressable, store the result in a temporary variable, then get
944 * codegen.cs: Only display 219 errors on warning level or above.
946 * expression.cs (ArrayAccess): Make it implement the
947 IMemoryLocation interface.
949 (Binary.DoResolve): handle the operator == (object a, object b)
950 and operator != (object a, object b) without incurring into a
951 BoxedCast (because 5 != o should never be performed).
953 Handle binary enumerator operators.
955 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
956 value type, otherwise use Ldelem_ref.
958 Use precomputed names;
960 (AddressOf): Implement address of
962 * cs-parser.jay (labeled_statement): Fix recursive block
963 addition by reworking the production.
965 * expression.cs (New.DoEmit): New has a special case:
967 If we are dealing with a ValueType, we have a few
968 situations to deal with:
970 * The target of New is a ValueType variable, that is
971 easy, we just pass this as the variable reference
973 * The target of New is being passed as an argument,
974 to a boxing operation or a function that takes a
977 In this case, we need to create a temporary variable
978 that is the argument of New.
981 2001-12-23 Ravi Pratap <ravi@ximian.com>
983 * rootcontext.cs (LookupType): Check that current_type is not null before
984 going about looking at nested types.
986 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
987 not implement the IAssignMethod interface any more.
989 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
990 where we tranform them into FieldExprs if they are being resolved from within
993 * ecore.cs (SimpleName.DoResolve): Do the same here.
995 * assign.cs (DoResolve, Emit): Clean up code considerably.
997 * ../errors/bug10.cs : Add.
999 * ../errors/cs0070.cs : Add.
1001 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
1003 * assign.cs : Get rid of EventIsLocal everywhere.
1005 2001-12-23 Miguel de Icaza <miguel@ximian.com>
1007 * ecore.cs (ConvertIntLiteral): finished the implementation.
1009 * statement.cs (SwitchLabel): Convert the value we are using as a
1010 key before looking up the table.
1012 2001-12-22 Miguel de Icaza <miguel@ximian.com>
1014 * codegen.cs (EmitTopBlock): Require a Location argument now.
1016 * cs-parser.jay (constructor_declarator): We need to setup
1017 current_local_parameters before we parse the
1018 opt_constructor_initializer, to allow the variables to be bound
1019 to the constructor arguments.
1021 * rootcontext.cs (LookupType): First lookup nested classes in our
1022 class and our parents before we go looking outside our class.
1024 * expression.cs (ConstantFold): Extract/debox the values at the
1027 * rootcontext.cs (EmitCode): Resolve the constants first before we
1028 resolve the types. This is not really needed, but it helps debugging.
1030 * statement.cs: report location.
1032 * cs-parser.jay: pass location to throw statement.
1034 * driver.cs: Small bug fix.
1036 * report.cs: Updated format to be 4-zero filled digits.
1038 2001-12-22 Ravi Pratap <ravi@ximian.com>
1040 * expression.cs (CheckIndices): Fix minor bug where the wrong
1041 variable was being referred to ;-)
1043 (DoEmit): Do not call EmitStaticInitializers when the
1044 underlying type is System.Object.
1046 2001-12-21 Ravi Pratap <ravi@ximian.com>
1048 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
1049 and do the usual workaround for SRE.
1051 * class.cs (MyEventBuilder.EventType): New member to get at the type
1052 of the event, quickly.
1054 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
1056 * assign.cs (Assign.DoResolve): Handle the case when the target
1057 is an EventExpr and perform the necessary checks.
1059 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
1062 (SimpleName.MemberStaticCheck): Include check for EventExpr.
1064 (EventExpr): Set the type in the constructor itself since we
1065 are meant to be born fully resolved.
1067 (EventExpr.Define): Revert code I wrote earlier.
1069 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
1070 instance expression is null. The instance expression is a This in that case
1071 or a null, depending on whether it is a static method or not.
1073 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
1074 refers to more than one method.
1076 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
1077 and accordingly flag errors.
1079 2001-12-21 Miguel de Icaza <miguel@ximian.com>
1081 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
1083 2001-12-22 Miguel de Icaza <miguel@ximian.com>
1085 * location.cs (ToString): Provide useful rutine.
1087 2001-12-21 Miguel de Icaza <miguel@ximian.com>
1089 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
1090 objects, return the actual integral boxed.
1092 * statement.cs (SwitchLabel): define an ILLabel for each
1095 (Switch.CheckSwitch): If the value is a Literal, extract
1096 the underlying literal.
1098 Also in the unused hashtable we had, add the SwitchLabel so we can
1099 quickly look this value up.
1101 * constant.cs: Implement a bunch of new constants. Rewrite
1102 Literal based on this. Made changes everywhere to adapt to this.
1104 * expression.cs (Expression.MakeByteBlob): Optimize routine by
1105 dereferencing array only once, and also copes with enumrations.
1107 bytes are two bytes wide, not one.
1109 (Cast): Perform constant conversions.
1111 * ecore.cs (TryImplicitIntConversion): Return literals instead of
1112 wrappers to the literals here.
1114 * expression.cs (DoNumericPromotions): long literals can converted
1115 to ulong implicity (this is taken care of elsewhere, but I was
1118 * ecore.cs (Expression.Literalize): Make the return type Literal,
1119 to improve type checking.
1121 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
1123 2001-12-20 Miguel de Icaza <miguel@ximian.com>
1125 * literal.cs: Revert code from ravi that checked the bounds. The
1126 bounds are sane by the definition of the type itself.
1128 * typemanager.cs: Fix implementation of ImplementsInterface. We
1129 need to actually look up in our parent hierarchy for interfaces
1132 * const.cs: Use the underlying type for enumerations
1134 * delegate.cs: Compute the basename for the delegate creation,
1135 that should fix the delegate test case, and restore the correct
1136 Type Lookup semantics in rootcontext
1138 * rootcontext.cs: Revert Ravi's last patch. The correct way of
1139 referencing a nested type with the Reflection API is using the "+"
1142 * cs-parser.jay: Do not require EOF token at the end.
1144 2001-12-20 Ravi Pratap <ravi@ximian.com>
1146 * rootcontext.cs (LookupType): Concatenate type names with
1147 a '.' instead of a '+' The test suite passes again.
1149 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
1150 field of the enumeration.
1152 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
1153 the case when the member is an EventExpr.
1155 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
1156 static has an associated instance expression.
1158 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
1160 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
1162 * class.cs (Event.Define): Register event and perform appropriate checks
1165 We define the Add and Remove methods even if the use provides none because
1166 in that case, we provide default implementations ourselves.
1168 Define a private field of the type of the event. This is done by the CSC compiler
1169 and we should be doing it too ;-)
1171 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
1172 More methods we use in code we generate.
1174 (multicast_delegate_type, delegate_type): Two separate types since the distinction
1177 (InitCoreTypes): Update accordingly for the above.
1179 * class.cs (Event.Emit): Generate code for default accessors that we provide
1181 (EmitDefaultMethod): Do the job in the above.
1183 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
1186 2001-12-20 Miguel de Icaza <miguel@ximian.com>
1188 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
1189 builders even if we were missing one.
1191 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
1192 pass the Basename as our class name instead of the Name. The
1193 basename will be correctly composed for us.
1195 * parameter.cs (Paramters): Now takes a Location argument.
1197 * decl.cs (DeclSpace.LookupType): Removed convenience function and
1198 make all the code call directly LookupType in RootContext and take
1199 this chance to pass the Location information everywhere.
1201 * Everywhere: pass Location information.
1203 2001-12-19 Miguel de Icaza <miguel@ximian.com>
1205 * class.cs (Constructor.Define): Updated way of detecting the
1206 length of the parameters.
1208 (TypeContainer.DefineType): Use basename as the type name for
1211 (TypeContainer.Define): Do not recursively define types here, as
1212 definition is taken care in order by the RootContext.
1214 * tree.cs: Keep track of namespaces in a per-file basis.
1216 * parameter.cs (Parameter.ComputeSignature): Update to use
1219 (Parameters.GetSignature): ditto.
1221 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
1222 instead of a TypeContainer.
1224 (Interface.SemanticAnalysis): Use `this' instead of our parent to
1225 resolve names. Because we need to be resolve in our context, not
1228 * driver.cs: Implement response files.
1230 * class.cs (TypeContainer.DefineType): If we are defined, do not
1233 (Event.Emit): Emit the code for add/remove handlers.
1234 (Event.Define): Save the MethodBuilders for add/remove.
1236 * typemanager.cs: Use pair here too.
1238 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
1239 DictionaryEntry requires the first argument to be non-null.
1241 (enum_declaration): Compute full name for registering the
1244 (delegate_declaration): Instead of using
1245 formal_parameter_list, use opt_formal_parameter_list as the list
1248 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
1249 (EventParsing): New property that controls whether `add' and
1250 `remove' are returned as tokens or identifiers (for events);
1252 2001-12-19 Ravi Pratap <ravi@ximian.com>
1254 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
1255 use MyEventBuilder only and let it wrap the real builder for us.
1257 (MyEventBuilder): Revamp constructor etc.
1259 Implement all operations that we perform on EventBuilder in precisely the same
1262 (FindMembers): Update to use the EventBuilder member.
1264 (Event.Emit): Update accordingly.
1266 2001-12-18 Ravi Pratap <ravi@ximian.com>
1268 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
1269 by calling the appropriate methods.
1271 (GetCustomAttributes): Make stubs as they cannot possibly do anything
1274 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
1276 2001-12-17 Ravi Pratap <ravi@ximian.com>
1278 * delegate.cs (Delegate.Populate): Check that the return type
1279 and various parameters types are indeed accessible.
1281 * class.cs (Constructor.Define): Same here.
1283 (Field.Define): Ditto.
1285 (Event.Define): Ditto.
1287 (Operator.Define): Check that the underlying Method defined itself
1288 correctly - so it's MethodBuilder should not be null.
1290 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
1291 expression happens to be null.
1293 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
1294 members but as of now we don't seem to be able to do anything really useful with it.
1296 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
1297 not the EventBuilder.
1299 2001-12-18 Miguel de Icaza <miguel@ximian.com>
1301 * cs-tokenizer.cs: Add support for defines.
1302 Add support for #if, #elif, #else, #endif
1304 (eval_var): evaluates a variable.
1305 (eval): stubbed for evaluating functions.
1307 * cs-parser.jay: Pass the defines information
1309 * driver.cs: Add --define command line option.
1311 * decl.cs: Move MemberCore here.
1313 Make it the base class for DeclSpace. This allows us to catch and
1314 report 108 and 109 for everything now.
1316 * class.cs (TypeContainer.Define): Extract all the members
1317 before populating and emit the warning 108 (new keyword required
1318 to override) instead of having each member implement this.
1320 (MemberCore.Define): New abstract method, we will be using this in
1321 the warning reporting engine in Populate.
1323 (Operator.Define): Adjust to new MemberCore protocol.
1325 * const.cs (Const): This does not derive from Expression, it is a
1326 temporary object we use to create fields, it is a MemberCore.
1328 * class.cs (Method.Define): Allow the entry point to be in a
1331 * driver.cs: Rewrite the argument handler to clean it up a bit.
1333 * rootcontext.cs: Made it just an auxiliary namespace feature by
1334 making everything static.
1336 * driver.cs: Adapt code to use RootContext type name instead of
1339 * delegate.cs: Remove RootContext argument.
1341 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
1344 * class.cs (Event.Define): The lookup can fail.
1346 * cs-tokenizer.cs: Begin implementation of pre-procesor.
1348 * expression.cs: Resolve the this instance before invoking the code.
1350 2001-12-17 Miguel de Icaza <miguel@ximian.com>
1352 * cs-parser.jay: Add a production in element_access that allows
1353 the thing to become a "type" reference. This way we can parse
1354 things like "(string [])" as a type.
1356 Note that this still does not handle the more complex rules of
1360 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
1362 * ecore.cs: (CopyNewMethods): new utility function used to
1363 assemble the list of methods from running FindMembers.
1365 (MemberLookup): Rework FindMembers so that
1367 2001-12-16 Miguel de Icaza <miguel@ximian.com>
1369 * class.cs (TypeContainer): Remove Delegates who fail to be
1372 * delegate.cs (Populate): Verify that we dont get null return
1373 values. TODO: Check for AsAccessible.
1375 * cs-parser.jay: Use basename to emit error 574 (destructor should
1376 have the same name as container class), not the full name.
1378 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
1379 possible representation.
1381 Also implements integer type suffixes U and L.
1383 2001-12-15 Miguel de Icaza <miguel@ximian.com>
1385 * expression.cs (ArrayCreation.DoResolve): We need to do the
1386 argument resolution *always*.
1388 * decl.cs: Make this hold the namespace. Hold the root context as
1390 (LookupType): Move here.
1392 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
1394 * location.cs (Row, Name): Fixed the code, it was always returning
1395 references to the first file.
1397 * interface.cs: Register properties defined through interfaces.
1399 * driver.cs: Add support for globbing on the command line
1401 * class.cs (Field): Make it derive from MemberCore as well.
1404 2001-12-15 Ravi Pratap <ravi@ximian.com>
1406 * class.cs (Event::Define): Check that the type of the event is a delegate
1407 type else flag error #66.
1409 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
1412 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
1413 values of EntryPoint, CharSet etc etc.
1415 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
1417 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
1418 be null and we should ignore this. I am not sure if this is really clean. Apparently,
1419 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
1420 which needs this to do its work.
1422 * ../errors/cs0066.cs : Add.
1424 2001-12-14 Miguel de Icaza <miguel@ximian.com>
1426 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
1429 * class.cs: (MethodSignature.MethodSignature): Removed hack that
1430 clears out the parameters field.
1431 (MemberSignatureCompare): Cleanup
1433 (MemberCore): New base class used to share code between MethodCore
1436 (RegisterRequiredImplementations) BindingFlags.Public requires
1437 either BindingFlags.Instace or Static. Use instance here.
1439 (Property): Refactored code to cope better with the full spec.
1441 * parameter.cs (GetParameterInfo): Return an empty array instead
1444 * class.cs (Property): Abstract or extern properties have no bodies.
1446 * parameter.cs (GetParameterInfo): return a zero-sized array.
1448 * class.cs (TypeContainer.MethodModifiersValid): Move all the
1449 method modifier validation to the typecontainer so we can reuse
1452 (MethodCore.ParameterTypes): return an empty sized array of types.
1454 (Property.Define): Test property modifier validity.

1467 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
1469 (ArrayCreation::MakeByteBlob): Handle floats and doubles.

1477 * class.cs (TypeContainer.Define): Correctly define explicit
1478 method implementations (they require the full interface name plus
1481 * typemanager.cs: Deply the PtrHashtable here and stop using the
1482 lame keys. Things work so much better.
1484 This of course broke everyone who depended on `RegisterMethod' to
1485 do the `test for existance' test. This has to be done elsewhere.
1487 * support.cs (PtrHashtable): A hashtable that avoid comparing with
1488 the object stupid Equals method (because, that like fails all over
1489 the place). We still do not use it.
1491 * class.cs (TypeContainer.SetRequiredInterface,
1492 TypeContainer.RequireMethods): Killed these two routines and moved
1493 all the functionality to RegisterRequiredImplementations.
1495 (TypeContainer.RegisterRequiredImplementations): This routine now
1496 registers all the implementations required in an array for the
1497 interfaces and abstract methods. We use an array of structures
1498 which can be computed ahead of time to reduce memory usage and we
1499 also assume that lookups are cheap as most classes will not
1500 implement too many interfaces.
1502 We also avoid creating too many MethodSignatures.
1504 (TypeContainer.IsInterfaceMethod): Update and optionally does not
1505 clear the "pending" bit if we find that there are problems with
1508 (TypeContainer.VerifyPendingMethods): Update to report errors of
1509 methods that look like implementations but are not.
1511 (TypeContainer.Define): Add support for explicit interface method
1514 2001-12-12 Miguel de Icaza <miguel@ximian.com>
1516 * typemanager.cs: Keep track of the parameters here instead of
1517 being a feature of the TypeContainer.
1519 * class.cs: Drop the registration of parameters here, as
1520 InterfaceMethods are also interface declarations.
1522 * delegate.cs: Register methods with the TypeManager not only with
1523 the TypeContainer. This code was buggy.
1525 * interface.cs: Full registation here.
1527 2001-12-11 Miguel de Icaza <miguel@ximian.com>
1529 * expression.cs: Remove reducer for binary expressions, it can not
1532 * const.cs: Put here the code that used to go into constant.cs
1534 * constant.cs: Put here the code for constants, this is a new base

1544 (Return.Emit): Instead of emitting a return, jump to the end of
1547 * codegen.cs (EmitContext): ReturnValue, ReturnLabel: new
1548 LocalBuilder to store the result of the function. ReturnLabel is
1549 the target where we jump.
1552 2001-12-09 Radek Doulik <rodo@ximian.com>
1554 * cs-parser.jay: remember alias in current namespace

1559 * class.cs (LookupAlias): lookup alias in my_namespace
1561 * namespace.cs (UsingAlias): add alias, namespace_or_type pair to
1563 (LookupAlias): lookup alias in this and if needed in parent
1566 2001-12-08 Miguel de Icaza <miguel@ximian.com>
1570 * rootcontext.cs: (ModuleBuilder) Made static, first step into
1571 making things static. I need this to avoid passing the
1572 TypeContainer when calling ParameterType.
1574 * support.cs (InternalParameters.ParameterType): Remove ugly hack
1575 that did string manipulation to compute the type and then call
1576 GetType. Use Parameter.ParameterType instead.
1578 * cs-tokenizer.cs: Consume the suffix for floating values.
1580 * expression.cs (ParameterReference): figure out whether this is a
1581 reference parameter or not. Kill an extra variable by computing
1582 the arg_idx during emission.
1584 * parameter.cs (Parameters.GetParameterInfo): New overloaded
1585 function that returns whether a parameter is an out/ref value or not.
1587 (Parameter.ParameterType): The type of the parameter (base,

1598 * statement.cs (Using.EmitLocalVariableDecls): Split the
1599 localvariable handling of the using statement.
1601 (Block.EmitMeta): Keep track of variable count across blocks. We
1602 were reusing slots on separate branches of blocks.
1604 (Try.Emit): Emit the general code block, we were not emitting it.
1606 Check the type of the declaration to be an IDisposable or
1607 something that can be implicity converted to it.
1609 Emit conversions if required.
1611 * ecore.cs (EmptyExpression): New utility class.
1612 (Expression.ImplicitConversionExists): New utility function.
1614 2001-12-06 Miguel de Icaza <miguel@ximian.com>
1616 * statement.cs (Using): Implement.

1620 * statement.cs: Remove the explicit emit for the Leave opcode.
1621 (VariableInfo): Add a readonly field.
1623 2001-12-05 Miguel de Icaza <miguel@ximian.com>
1625 * ecore.cs (ConvCast): new class used to encapsulate the various
1626 explicit integer conversions that works in both checked and
1629 (Expression.ConvertNumericExplicit): Use new ConvCast class to
1630 properly generate the overflow opcodes.
1632 2001-12-04 Miguel de Icaza <miguel@ximian.com>
1634 * statement.cs: The correct type for the EmptyExpression is the
1635 element_type, not the variable type. Ravi pointed this out.
1637 2001-12-04 Ravi Pratap <ravi@ximian.com>
1639 * class.cs (Method::Define): Handle PInvoke methods specially
1640 by using DefinePInvokeMethod instead of the usual one.
1642 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
1643 above to do the task of extracting information and defining the method.
1645 2001-12-04 Ravi Pratap <ravi@ximian.com>
1647 * expression.cs (ArrayCreation::EmitStaticInitializers): Get rid
1648 of the condition for string type.

1669 * statement.cs (GotoDefault), cs-parser.jay: Implement `goto
1672 (Foreach.Emit): Foreach on arrays was not setting
1673 up the loop variables (for break/continue).
1675 (GotoCase): Semi-implented.
1677 2001-12-03 Ravi Pratap <ravi@ximian.com>

1727 As that share bits of the implementation. Is returns a boolean,
1728 while As returns the Type that is being probed.
1730 2001-12-01 Ravi Pratap <ravi@ximian.com>
1732 * enum.cs (LookupEnumValue): Re-write various bits, return an object value
1733 instead of a Literal - much easier.
1735 (EnumInTransit): Remove - utterly useless :-)
1737 (Populate): Re-write bits - remove duplicate code etc. The code is much neater now.
1739 * expression.cs (MemberLookup): Cope with user-defined enums when they are in transit.

1834 directly from ArrayData now.
1836 (ExpectInitializers): Keep track of whether initializers are mandatory
1839 (Bounds): Make it a hashtable to prevent the same dimension being
1840 recorded for every element in that dimension.

1889 2001-11-22 Miguel de Icaza <miguel@ximian.com>
1891 * statement.cs (If.Emit): Fix a bug that generated incorrect code
1892 on If. Basically, we have to return `true' (ie, we do return to
1893 our caller) only if both branches of the if return.

1902 allowed a limited set of types to be handled. Now we take a
1903 unary_expression and we resolve to a type during semantic
1906 Use the grammar productions from Rhys to handle casts (this is
1907 not complete like Rhys syntax yet, we fail to handle that corner
1908 case that C# has regarding (-x), but we will get there.

1955 (Expression.ImplicitNumericConversion): Oops, forgot to test for

1959 2001-11-21 Miguel de Icaza <miguel@ximian.com>
1961 * cs-parser.jay (for_statement): Reworked the way For works: now
1962 we declare manually any variables that are introduced in
1963 for_initializer to solve the problem of having out-of-band code
1964 emition (that is what got for broken).
1966 (declaration_statement): Perform the actual variable declaration
1967 that used to be done in local_variable_declaration here.
1969 (local_variable_declaration): Do not declare anything, just pass
1970 the information on a DictionaryEntry
1972 2001-11-20 Ravi Pratap <ravi@ximian.com>

2037 we can use this elsewhere.
2039 * statement.cs: Finish implementation of foreach for single
2042 * cs-parser.jay: Use an out-of-band stack to pass information
2043 around, I wonder why I need this.
2045 foreach_block: Make the new foreach_block the current_block.
2047 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
2048 function used to return a static Parameters structure. Used for
2049 empty parameters, as those are created very frequently.
2051 * cs-parser.jay, class.cs: Use GetEmptyReadOnlyParameters
2053 2001-11-15 Ravi Pratap <ravi@ximian.com>
2055 * interface.cs : Default modifier is private, not public. The

2058 2001-11-15 Ravi Pratap <ravi@ximian.com>
2060 * support.cs (ReflectionParameters): Fix logic to determine
2061 whether the last parameter is a params one. Test 9 passes again.

2115 way we can report the error correctly for missing return values.
2117 * class.cs (Method.Emit): Clean up.
2119 * expression.cs (Argument.Resolve): Take another argument: the
2120 location where this argument is used. Notice that this is not
2121 part of the "Argument" class as to reduce the size of the
2122 structure (we know the approximate location anyways).
2124 Test if the argument is a variable-reference, if not, then
2125 complain with a 206.
2127 (Argument.Emit): Emit addresses of variables.
2129 (Argument.FullDesc): Simplify.
2131 (Invocation.DoResolve): Update for Argument.Resolve.
2133 (ElementAccess.DoResolve): ditto.

2164 * expression.cs (UnaryMutator): New class, used to handle ++ and
2165 -- separatedly from the other unary operators. Cleans up the
2166 code, and kills the ExpressionStatement dependency in Unary.

2849 * delegate.cs (VerifyMethod): Implement to check if the given method
2850 matches the delegate.

2861 * ../errors/cs1593.cs : Added.
2863 * ../errors/cs1594.cs : Added.

2904 loop and end of the loop).
2906 2001-10-15 Ravi Pratap <ravi@ximian.com>
2908 * delegate.cs (Emit): Get rid of it as there doesn't seem to be any ostensible
2909 use of emitting anything at all.
2911 * class.cs, rootcontext.cs : Get rid of calls to the same.
2913 * delegate.cs (DefineDelegate): Make sure the class we define is also sealed.

2923 (IsDelegateType): Implement helper method.
2925 * delegate.cs (DefineDelegate): Use AddDelegateType instead of AddUserType.
2927 * expression.cs (New::DoResolve): Check if we are trying to instantiate a delegate type
2928 and accordingly handle it.
2930 * delegate.cs (Populate): Take TypeContainer argument.
2931 Implement bits to define the Invoke method. However, I still haven't figured out
2932 how to take care of the native int bit :-(
2934 * cs-parser.jay (delegate_declaration): Fixed the bug that I had introduced :-)
2935 Qualify the name of the delegate, not its return type !
2937 * expression.cs (ImplicitReferenceConversion): Implement guts of implicit array
2940 (StandardConversionExists): Checking for array types turns out to be recursive.
2942 (ConvertReferenceExplicit): Implement array conversion.

2948 * cs-parser.jay (delegate_declaration): Store the fully qualified
2949 name as it is a type declaration.
2951 * delegate.cs (ReturnType, Name): Rename members to these. Make them
2954 (DefineDelegate): Renamed from Define. Does the same thing essentially,
2955 as TypeContainer::DefineType.
2957 (Populate): Method in which all the definition of the various methods (Invoke)
2960 (Emit): Emit any code, if necessary. I am not sure about this really, but let's
2963 (CloseDelegate): Finally creates the delegate.
2965 * class.cs (TypeContainer::DefineType): Update to define delegates.
2966 (Populate, Emit and CloseType): Do the same thing here too.

2977 provide the proper semantic access to properties.
2979 * expression.cs (Expression::ConvertReferenceExplicit): Implement
2980 a few more explicit conversions.
2982 * modifiers.cs: `NEW' modifier maps to HideBySig.

2985 ExpressionStatement, and support the EmitStatement code path.
2987 Perform get/set error checking, clean up the interface.

2990 them into toplevel access objects.

3007 (This::LValueResolve): Implement.
3009 (This::Store): Remove warning, assigning to `this' in structures
3012 (Invocation::Emit): Deal with invocation of
3013 methods on value types. We need to pass the address to structure
3014 methods rather than the object itself. (The equivalent code to
3015 emit "this" for structures leaves the entire structure on the
3016 stack instead of a pointer to it).
3018 (ParameterReference::DoResolve): Compute the real index for the
3019 argument based on whether the method takes or not a `this' pointer
3020 (ie, the method is static).
3022 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store
3023 value types returned from functions when we need to invoke a
3024 method on the sturcture.
3027 2001-10-11 Ravi Pratap <ravi@ximian.com>
3029 * class.cs (TypeContainer::DefineType): Method to actually do the business of
3030 defining the type in the Modulebuilder or Typebuilder. This is to take
3031 care of nested types which need to be defined on the TypeBuilder using
3034 (TypeContainer::GetClassBases): Implement. Essentially the code from the
3035 methods in RootContext, only ported to be part of TypeContainer.
3037 (TypeContainer::GetInterfaceOrClass): Ditto.
3039 (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
3041 * interface.cs (Interface::DefineInterface): New method. Does exactly
3042 what RootContext.CreateInterface did earlier, only it takes care of nested types
3045 (Interface::GetInterfaces): Move from RootContext here and port.
3047 (Interface::GetInterfaceByName): Same here.
3049 * rootcontext.cs (ResolveTree): Re-write.

3057 instead just use the name argument passed in as it is already fully
3060 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
3061 to TypeContainer mapping to see if a type is user-defined.
3063 * class.cs (TypeContainer::CloseType): Implement.
3065 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
3066 the default constructor.
3068 (TypeContainer::Populate): Fix minor bug which led to creating default constructors
3071 (Constructor::IsDefault): Fix up logic to determine if it is the default constructor
3073 * interface.cs (CloseType): Create the type here.
3075 * rootcontext.cs (CloseTypes): Re-write to recursively close types by running through
3078 Remove all the methods which are now in TypeContainer.

3085 2001-10-10 Miguel de Icaza <miguel@ximian.com>
3087 * makefile: Renamed the compiler to `mcs.exe' instead of compiler.exe
3089 * expression.cs (ImplicitReferenceConversion): handle null as well
3090 as a source to convert to any reference type.
3092 * statement.cs (Return): Perform any implicit conversions to
3093 expected return type.
3095 Validate use of return statement.
3097 * codegen.cs (EmitContext): Pass the expected return type here.
3099 * class.cs (Method, Constructor, Property): Pass expected return
3100 type to EmitContext.
3102 2001-10-09 Miguel de Icaza <miguel@ximian.com>
3104 * expression.cs: Make DoResolve take an EmitContext instead of a
3107 Replaced `l' and `location' for `loc', for consistency.
3109 (Error, Warning): Remove unneeded Tc argument.
3111 * assign.cs, literal.cs, constant.cs: Update to new calling
3114 * codegen.cs: EmitContext now contains a flag indicating whether
3115 code is being generated in a static method or not.
3117 * cs-parser.jay: DecomposeQI, new function that replaces the old
3118 QualifiedIdentifier. Now we always decompose the assembled
3119 strings from qualified_identifier productions into a group of
3122 2001-10-08 Miguel de Icaza <miguel@ximian.com>
3124 * rootcontext.cs: Deal with field-less struct types correctly now
3125 by passing the size option to Define Type.
3127 * class.cs: Removed hack that created one static field.
3129 2001-10-07 Miguel de Icaza <miguel@ximian.com>
3131 * statement.cs: Moved most of the code generation here.
3133 2001-10-09 Ravi Pratap <ravi@ximian.com>
3135 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
3138 (ElementAccess): Remove useless bits for now - keep checks as the spec
3141 2001-10-08 Ravi Pratap <ravi@ximian.com>
3143 * expression.cs (ElementAccess::DoResolve): Remove my crap code
3144 and start performing checks according to the spec.
3146 2001-10-07 Ravi Pratap <ravi@ximian.com>
3148 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
3149 rank_specifiers instead.

3157 2001-10-06 Ravi Pratap <ravi@ximian.com>
3159 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
3160 except that user defined conversions are not included.
3162 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
3163 perform the conversion of the return type, if necessary.
3165 (New::DoResolve): Check whether we are creating an array or an object
3166 and accordingly do the needful.
3168 (New::Emit): Same here.
3170 (New::DoResolve): Implement guts of array creation.
3172 (New::FormLookupType): Helper function.
3174 2001-10-07 Miguel de Icaza <miguel@ximian.com>

3177 corresponding code generation bits to the statement classes.
3179 Added support for try/catch/finalize and throw.
3181 * cs-parser.jay: Added support for try/catch/finalize.
3183 * class.cs: Catch static methods having the flags override,
3184 virtual or abstract.
3186 * expression.cs (UserCast): This user cast was not really doing
3187 what it was supposed to do. Which is to be born in fully resolved
3188 state. Parts of the resolution were being performed at Emit time!
3192 2001-10-05 Miguel de Icaza <miguel@ximian.com>
3194 * expression.cs: Implicity convert the result from UserCast.
3196 2001-10-05 Ravi Pratap <ravi@ximian.com>
3198 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
3199 prevented it from working correctly.
3201 (ConvertExplicit): Make the first try, a call to ConvertImplicitStandard, not
3202 merely ConvertImplicit.

3206 * typemanager.cs: Make the LookupTypeContainer function static,
3207 and not per-instance.
3209 * class.cs: Make static FindMembers (the one that takes a Type
3212 * codegen.cs: Add EmitForeach here.
3214 * cs-parser.jay: Make foreach a toplevel object instead of the
3215 inline expansion, as we need to perform semantic analysis on it.

3219 * expression.cs (Expression::ImplicitUserConversion): Rename to
3220 UserDefinedConversion.
3222 (Expression::UserDefinedConversion): Take an extra argument specifying
3223 whether we look for explicit user conversions too.

3234 * expression.cs (Cast): Record location info.
3236 (Expression::ConvertExplicit): Take location argument.
3238 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
3239 to determine if we are doing explicit conversions.
3241 (UserCast::Emit): Update accordingly.
3243 (Expression::ConvertExplicit): Report an error if everything fails.
3245 * ../errors/cs0030.cs : Add.
3247 2001-10-04 Miguel de Icaza <miguel@ximian.com>
3249 * modifiers.cs: If the ABSTRACT keyword is present, also set the
3250 virtual and newslot bits.
3252 * class.cs (TypeContainer::RegisterRequiredImplementations):
3253 Record methods we need.
3255 (TypeContainer::MakeKey): Helper function to make keys for
3256 MethodBases, since the Methodbase key is useless.
3258 (TypeContainer::Populate): Call RegisterRequiredImplementations
3259 before defining the methods.
3261 Create a mapping for method_builders_to_methods ahead of time
3262 instead of inside a tight loop.
3264 (::RequireMethods): Accept an object as the data to set into the
3265 hashtable so we can report interface vs abstract method mismatch.
3267 2001-10-03 Miguel de Icaza <miguel@ximian.com>
3269 * report.cs: Make all of it static.
3271 * rootcontext.cs: Drop object_type and value_type computations, as
3272 we have those in the TypeManager anyways.
3274 Drop report instance variable too, now it is a global.
3276 * driver.cs: Use try/catch on command line handling.
3278 Add --probe option to debug the error reporting system with a test
3281 * report.cs: Add support for exiting program when a probe
3282 condition is reached.
3284 2001-10-03 Ravi Pratap <ravi@ximian.com>
3286 * expression.cs (Binary::DoNumericPromotions): Fix the case when
3287 we do a forcible conversion regardless of type, to check if
3288 ForceConversion returns a null.
3290 (Binary::error19): Use location to report error.
3292 (Unary::error23): Use location here too.
3294 * ../errors/cs0019.cs : Check in.
3296 * ../errors/cs0023.cs : Check in.
3298 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
3299 case of a non-null MethodInfo object with a length of 0 !
3301 (Binary::ResolveOperator): Flag error if overload resolution fails to find
3302 an applicable member - according to the spec :-)
3303 Also fix logic to find members in base types.
3305 (Unary::ResolveOperator): Same here.
3307 (Unary::report23): Change name to error23 and make first argument a TypeContainer
3308 as I was getting thoroughly confused between this and error19 :-)
3310 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
3311 (::FindMostEncompassedType): Implement.
3312 (::FindMostEncompassingType): Implement.
3313 (::StandardConversionExists): Implement.
3315 (UserImplicitCast): Re-vamp. We now need info about most specific
3316 source and target types so that we can do the necessary conversions.
3318 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
3319 mathematical union with no duplicates.
3321 2001-10-03 Miguel de Icaza <miguel@ximian.com>
3323 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
3324 in order from base classes to child classes, so that we can in
3325 child classes look up in our parent for method names and
3326 attributes (required for handling abstract, virtual, new, override
3327 constructs: we need to instrospect our base class, and if we dont
3328 populate the classes in order, the introspection might be
3329 incorrect. For example, a method could query its parent before
3330 the parent has any methods and would determine that the parent has
3331 no abstract methods (while it could have had them)).
3333 (RootContext::CreateType): Record the order in which we define the
3336 2001-10-02 Miguel de Icaza <miguel@ximian.com>
3338 * class.cs (TypeContainer::Populate): Also method definitions can
3339 fail now, keep track of this.
3341 (TypeContainer::FindMembers): Implement support for
3342 DeclaredOnly/noDeclaredOnly flag.
3344 (Constructor::Emit) Return the ConstructorBuilder.
3346 (Method::Emit) Return the MethodBuilder.
3347 Check for abstract or virtual methods to be public.
3349 * rootcontext.cs (RootContext::CreateType): Register all the
3350 abstract methods required for the class to be complete and the
3351 interface methods that must be implemented.
3353 * cs-parser.jay: Report error 501 (method requires body if it is
3354 not marked abstract or extern).
3356 * expression.cs (TypeOf::Emit): Implement.
3358 * typemanager.cs: runtime_handle_type, new global type.
3360 * class.cs (Property::Emit): Generate code for properties.
3362 2001-10-02 Ravi Pratap <ravi@ximian.com>
3364 * expression.cs (Unary::ResolveOperator): Find operators on base type
3365 too - we now conform exactly to the spec.
3367 (Binary::ResolveOperator): Same here.
3369 * class.cs (Operator::Define): Fix minor quirk in the tests.
3371 * ../errors/cs0215.cs : Added.
3373 * ../errors/cs0556.cs : Added.
3375 * ../errors/cs0555.cs : Added.
3377 2001-10-01 Miguel de Icaza <miguel@ximian.com>
3379 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
3380 single integer which is really efficient
3382 2001-10-01 Ravi Pratap <ravi@ximian.com>
3384 * expression.cs (Expression::ImplicitUserConversion): Use location
3385 even in the case when we are examining True operators.
3387 * class.cs (Operator::Define): Perform extensive checks to conform
3388 with the rules for operator overloading in the spec.

3391 some of the other conversions mentioned in the spec.

3396 (cloneable_interface): For System.ICloneable interface.
3398 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
3399 we start resolving the tree and populating types.
3401 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
3403 2001-10-01 Miguel de Icaza <miguel@ximian.com>
3405 * expression.cs (Expression::ExprClassFromMemberInfo,
3406 Expression::Literalize): Create literal expressions from
3407 FieldInfos which are literals.
3409 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
3410 type casts, because they were wrong. The test suite in tests
3413 (ImplicitNumericConversion): ushort to ulong requires a widening
3416 Int32 constant to long requires widening cast as well.
3418 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
3419 for integers because the type on the stack is not i4.
3421 2001-09-30 Miguel de Icaza <miguel@ximian.com>
3423 * expression.cs (report118): require location argument.
3425 * parameter.cs: Do not dereference potential null value.
3427 * class.cs: Catch methods that lack the `new' keyword when
3428 overriding a name. Report warnings when `new' is used without
3429 anything being there to override.
3431 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
3433 * class.cs: Only add constructor to hashtable if it is non-null
3434 (as now constructors can fail on define).
3436 (TypeManager, Class, Struct): Take location arguments.
3438 Catch field instance initialization in structs as errors.
3440 accepting_filter: a new filter for FindMembers that is static so
3441 that we dont create an instance per invocation.
3443 (Constructor::Define): Catch errors where a struct constructor is
3446 * cs-parser.jay: Pass location information for various new
3449 * delegate.cs (Delegate): take a location argument.
3451 * driver.cs: Do not call EmitCode if there were problesm in the
3452 Definition of the types, as many Builders wont be there.
3454 * decl.cs (Decl::Decl): Require a location argument.
3456 * cs-tokenizer.cs: Handle properly hex constants that can not fit
3457 into integers, and find the most appropiate integer for it.
3459 * literal.cs: Implement ULongLiteral.
3461 * rootcontext.cs: Provide better information about the location of
3462 failure when CreateType fails.
3464 2001-09-29 Miguel de Icaza <miguel@ximian.com>
3466 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
3469 * expression.cs (Binary::CheckShiftArguments): Add missing type
3471 (Binary::ResolveOperator): Add type to the logical and and logical
3472 or, Bitwise And/Or and Exclusive Or code paths, it was missing
3475 (Binary::DoNumericPromotions): In the case where either argument
3476 is ulong (and most signed types combined with ulong cause an
3477 error) perform implicit integer constant conversions as well.
3479 2001-09-28 Miguel de Icaza <miguel@ximian.com>
3481 * expression.cs (UserImplicitCast): Method should always be
3483 (Invocation::BetterConversion): Simplified test for IntLiteral.
3485 (Expression::ImplicitNumericConversion): Split this routine out.
3486 Put the code that performs implicit constant integer conversions
3489 (Expression::Resolve): Become a wrapper around DoResolve so we can
3490 check eclass and type being set after resolve.
3492 (Invocation::Badness): Remove this dead function
3494 (Binary::ResolveOperator): Do not compute the expensive argumnets
3495 unless we have a union for it.
3497 (Probe::Emit): Is needs to do an isinst and then
3498 compare against null.
3500 (::CanConvert): Added Location argument. If the Location argument
3501 is null (Location.Null), then we do not report errors. This is
3502 used by the `probe' mechanism of the Explicit conversion. We do
3503 not want to generate an error for something that the user
3504 explicitly requested to be casted. But the pipeline for an
3505 explicit cast first tests for potential implicit casts.
3507 So for now, if the Location is null, it means `Probe only' to
3508 avoid adding another argument. Might have to revise this
3511 (ClassCast): New class used to type cast objects into arbitrary
3512 classes (used in Explicit Reference Conversions).
3514 Implement `as' as well.
3516 Reverted all the patches from Ravi below: they were broken:
3518 * The use of `level' as a mechanism to stop recursive
3519 invocations is wrong. That was there just to catch the
3520 bug with a strack trace but not as a way of addressing
3523 To fix the problem we have to *understand* what is going
3524 on and the interactions and come up with a plan, not
3525 just get things going.
3527 * The use of the type conversion cache that I proposed
3528 last night had an open topic: How does this work across
3529 protection domains. A user defined conversion might not
3530 be public in the location where we are applying the
3531 conversion, a different conversion might be selected
3532 (ie, private A->B (better) but public B->A (worse),
3533 inside A, A->B applies, but outside it, B->A will
3536 * On top of that (ie, even if the above is solved),
3537 conversions in a cache need to be abstract. Ie, `To
3538 convert from an Int to a Short use an OpcodeCast', not
3539 `To convert from an Int to a Short use the OpcodeCast on
3540 the variable 5' (which is what this patch was doing).
3542 2001-09-28 Ravi Pratap <ravi@ximian.com>
3544 * expression.cs (Invocation::ConversionExists): Re-write to use
3545 the conversion cache
3547 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
3548 cache all conversions done, not just user-defined ones.
3550 (Invocation::BetterConversion): The real culprit. Use ConversionExists
3551 to determine if a conversion exists instead of acutually trying to
3552 perform the conversion. It's faster too.
3554 (Expression::ConvertExplicit): Modify to use ConversionExists to check
3555 and only then attempt the implicit conversion.
3557 2001-09-28 Ravi Pratap <ravi@ximian.com>
3559 * expression.cs (ConvertImplicit): Use a cache for conversions
3560 already found. Check level of recursion and bail out if necessary.

3575 * codegen.cs: remove unnneded code
3577 * expression.cs: Removed BuiltinTypeAccess class
3579 Fix the order in which implicit conversions are
3582 The previous fixed dropped support for boxed conversions (adding a
3583 test to the test suite now)
3585 (UserImplicitCast::CanConvert): Remove test for source being null,
3586 that code is broken. We should not feed a null to begin with, if
3587 we do, then we should track the bug where the problem originates
3588 and not try to cover it up here.
3590 Return a resolved expression of type UserImplicitCast on success
3591 rather than true/false. Ravi: this is what I was talking about,
3592 the pattern is to use a static method as a "constructor" for
3595 Also, do not create arguments until the very last minute,
3596 otherwise we always create the arguments even for lookups that
3597 will never be performed.
3599 (UserImplicitCast::Resolve): Eliminate, objects of type
3600 UserImplicitCast are born in a fully resolved state.
3602 * typemanager.cs (InitCoreTypes): Init also value_type
3605 * expression.cs (Cast::Resolve): First resolve the child expression.
3607 (LValue): Add new method AddressOf to be used by
3610 Change the argument of Store to take an EmitContext instead of an
3611 ILGenerator, because things like FieldExpr need to be able to call
3612 their children expression to generate the instance code.
3614 (Expression::Error, Expression::Warning): Sugar functions for
3617 (Expression::MemberLookup): Accept a TypeContainer instead of a
3618 Report as the first argument.
3620 (Expression::ResolvePrimary): Killed. I still want to improve
3621 this as currently the code is just not right.
3623 (Expression::ResolveMemberAccess): Simplify, but it is still
3626 (Unary::Resolve): Catch errors in AddressOf operators.
3628 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
3629 index to a byte for the short-version, or the compiler will choose
3630 the wrong Emit call, which generates the wrong data.
3632 (ParameterReference::Emit, ::Store): same.
3634 (FieldExpr::AddressOf): Implement.
3636 * typemanager.cs: TypeManager: made public variable instead of
3639 * driver.cs: document --fatal.
3641 * report.cs (ErrorMessage, WarningMessage): new names for the old
3642 Error and Warning classes.
3644 * cs-parser.jay (member_access): Turn built-in access to types
3645 into a normal simplename
3647 2001-09-27 Ravi Pratap <ravi@ximian.com>

3650 with q being null, since this was introducing a bug.
3652 * expression.cs (ConvertImplicit): Do built-in conversions first.
3654 2001-09-27 Ravi Pratap <ravi@ximian.com>
3656 * expression.cs (UserImplicitCast::Resolve): Fix bug.
3658 2001-09-27 Ravi Pratap <ravi@ximian.com>
3660 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
3661 I had introduced long ago (what's new ?).
3663 * expression.cs (UserImplicitCast::CanConvert): Static method to do
3664 the work of all the checking.
3665 (ConvertImplicit): Call CanConvert and only then create object if necessary.
3666 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
3668 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
3669 that is the right way.
3671 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
3672 overloading resolution. Use everywhere instead of cutting and pasting code.
3674 (Binary::ResolveOperator): Use MakeUnionSet.
3676 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
3677 we have to convert to bool types. Not complete yet.
3679 2001-09-27 Miguel de Icaza <miguel@ximian.com>
3681 * typemanager.cs (TypeManager::CSharpName): support ushort.
3683 * expression.cs (Expression::TryImplicitIntConversion): Attempts
3684 to provide an expression that performsn an implicit constant int
3685 conversion (section 6.1.6).
3686 (Expression::ConvertImplicitRequired): Reworked to include
3687 implicit constant expression conversions.
3689 (Expression::ConvertNumericExplicit): Finished.
3691 (Invocation::Emit): If InstanceExpression is null, then it means
3692 that we perform a call on this.
3694 2001-09-26 Miguel de Icaza <miguel@ximian.com>
3696 * expression.cs (Unary::Emit): Remove some dead code.
3697 (Probe): Implement Resolve and Emit for `is'.
3698 (Expression::ConvertImplicitRequired): Attempt to do constant
3699 expression conversions here. Maybe should be moved to
3700 ConvertImplicit, but I am not sure.
3701 (Expression::ImplicitLongConstantConversionPossible,
3702 Expression::ImplicitIntConstantConversionPossible): New functions
3703 that tell whether is it possible to apply an implicit constant
3704 expression conversion.

3713 (Parameters::VerifyArgs): Verifies that no two arguments have the
3716 * class.cs (Operator): Update the operator names to reflect the
3717 ones that the spec expects (as we are just stringizing the
3720 * expression.cs (Unary::ResolveOperator): Fix bug: Use
3721 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
3722 previous usage did only work for our methods.
3723 (Expression::ConvertImplicit): Handle decimal implicit numeric
3724 conversions as well.
3725 (Expression::InternalTypeConstructor): Used to invoke constructors
3726 on internal types for default promotions.
3728 (Unary::Emit): Implement special handling for the pre/post
3729 increment/decrement for overloaded operators, as they need to have
3730 the same semantics as the other operators.
3732 (Binary::ResolveOperator): ditto.

3743 (Invocation::OverloadResolve): Ditto.
3744 (Invocation::BetterFunction, BetterConversion, ConversionExists): Ditto.

3750 * assign.cs (Assign): Make it inherit from ExpressionStatement.
3752 * expression.cs (ExpressionStatement): New base class used for
3753 expressions that can appear in statements, so that we can provide
3754 an alternate path to generate expression that do not leave a value
3757 (Expression::Emit, and all the derivatives): We no longer return
3758 whether a value is left on the stack or not. Every expression
3759 after being emitted leaves a single value on the stack.
3761 * codegen.cs (EmitContext::EmitStatementExpression): Use the
3762 facilties of ExpressionStatement if possible.
3764 * cs-parser.jay: Update statement_expression.

3785 (ConvertImplicit): Do user-defined conversion if it exists.
3787 2001-09-24 Miguel de Icaza <miguel@ximian.com>
3789 * assign.cs: track location.
3790 (Resolve): Use implicit conversions on assignment.

3833 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
3834 Also take an additional TypeContainer argument.

3855 * typemanager.cs: declare and load enum_type, delegate_type and
3858 * expression.cs (Expression::Emit): Now emit returns a value that
3859 tells whether a value is left on the stack or not. This strategy
3860 might be reveted tomorrow with a mechanism that would address
3861 multiple assignments.
3862 (Expression::report118): Utility routine to report mismatches on
3865 (Unary::Report23): Report impossible type/operator combination

3914 functions, throw exceptions so it is obvious that we are facing a
3917 * cs-parser.jay (invocation_expression): Pass Location information.
3919 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
3920 Use a basename for those routines because .NET does not like paths

3935 expressions (otherwise they are Unary {Literal}).
3936 (Invocation::Badness): Take into account `Implicit constant
3937 expression conversions'.

3940 (IntLiteral): export the `Value' of the intliteral.
3942 2001-09-19 Ravi Pratap <ravi@ximian.com>

3957 * expression.cs (Unary::Resolve): Implement.
3958 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
3959 operators are found instead of making noise ;-)
3960 (Unary::ResolveOperator): New method to do precisely the same thing which
3961 Binary::ResolveOperator does for Binary expressions.
3962 (Unary.method, .Arguments): Add.
3963 (Unary::OperName): Implement.
3964 (Unary::ForceConversion): Copy and Paste !
3966 * class.cs (Operator::Define): Fix a small bug for the case when we have
3969 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes

3972 2001-09-18 Miguel de Icaza <miguel@ximian.com>
3974 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
3975 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

3988 (FieldExpr::Emit): Implement.
3990 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
3991 the last instruction contains a return opcode to avoid generating
3992 the last `ret' instruction (this generates correct code, and it is
3993 nice to pass the peverify output).
3995 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
3996 initializer for static and instance variables.
3997 (Constructor::Emit): Allow initializer to be null in the case of
3998 static constructors. Only emit initializer for instance
4001 (TypeContainer::FindMembers): Return a null array if there are no

4011 * driver.cs: Stop compilation if there are parse errors.
4013 * cs-parser.jay (constructor_declaration): Provide default base

4019 * class.cs: Do not emit parent class initializers for static
4020 constructors, that should be flagged as an error.
4022 2001-09-18 Ravi Pratap <ravi@ximian.com>
4024 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
4025 Move back code into TypeContainer::Populate.

4051 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
4054 (Expression::MemberLookup): Provide a version that allows to
4055 specify the MemberTypes and BindingFlags.
4057 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
4058 so it was not fetching variable information from outer blocks.
4060 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
4061 Beforefieldinit as it was buggy.
4063 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
4066 * class.cs (Constructor::Emit): Only emit if block is not null.
4067 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
4068 deal with this by semantically definining it as if the user had
4071 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
4072 constructors as we now "emit" them at a higher level.

4075 default constructors if none was provided.
4077 (ConstructorInitializer): Add methods Resolve and Emit.
4079 * expression.cs: Cast to ConstructorInfo instead of MethodInfo
4081 2001-09-17 Ravi Pratap <ravi@ximian.com>

4105 we have overloaded operators.
4106 (Binary::ResolveOperator): Implement the part which does the operator overload
4109 * class.cs (Operator::Emit): Implement.
4110 (TypeContainer::Emit): Emit the operators we have too.
4112 * expression.cs (Binary::Emit): Update to emit the appropriate code for
4113 the case when we have a user-defined operator.
4115 2001-09-17 Miguel de Icaza <miguel@ximian.com>
4117 * rootcontext.cs: Fix bug: tree.Namespaces might be null.
4119 2001-09-16 Ravi Pratap <ravi@ximian.com>
4121 * class.cs (EmitStaticFieldInitializers, EmitFieldInitializers): Make public.
4122 (TypeContainer::EmitConstructor): Remove and move code into Contructor::Emit.
4123 (Constructor::Emit): Implement.
4124 (EmitStaticFieldInitializers, EmitFieldInitializers): Ensure we return immediately

4145 * rootcontext.cs (IsNamespace): Fixed it :-)
4147 2001-09-14 Miguel de Icaza <miguel@ximian.com>
4149 * class.cs (TypeContainer::FindMembers): Add support for
4151 (MethodCore): New class that encapsulates both the shared aspects
4152 of a Constructor and a Method.

4156 Load System assembly as well as part of the standard library.
4158 * report.cs: Allow throwing exceptions on errors for debugging.
4160 * modifiers.cs: Do not use `parent', instead use the real type
4161 container to evaluate permission settings.
4163 * class.cs: Put Ravi's patch back in. He is right, and we will
4164 have to cope with the
4166 2001-09-14 Ravi Pratap <ravi@ximian.com>
4168 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

4176 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
4177 incorrect. IsTopLevel is not used to tell whether an object is
4178 root_types or not (that can be achieved by testing this ==
4179 root_types). But to see if this is a top-level *class* (not
4180 necessarly our "toplevel" container).
4182 2001-09-14 Ravi Pratap <ravi@ximian.com>
4184 * enum.cs (Enum::Define): Modify to call the Lookup method on the
4185 parent instead of a direct call to GetType.
4187 2001-09-14 Ravi Pratap <ravi@ximian.com>
4189 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
4190 Modifiers.TypeAttr. This should just be a call to that method.
4192 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer

4212 2001-09-13 Miguel de Icaza <miguel@ximian.com>
4214 * expression.cs (MemberLookup): Fruitless attempt to lookup

4270 (Class::LookupMethodByBuilder): New function that maps
4271 MethodBuilders to its methods. Required to locate the information
4272 on methods because System.Reflection bit us again.
4274 * support.cs: New file, contains an interface ParameterData and
4275 two implementations: ReflectionParameters and InternalParameters
4276 used to access Parameter information. We will need to grow this
4279 * expression.cs (Invocation::GetParameterData): implement a cache
4280 and a wrapper around the ParameterData creation for methods.

4439 on the name without any prefixes of namespace names etc. This is because we
4440 already might have something already fully qualified like
4441 'System.Console.WriteLine'

4592 will is used during the tree rewriting as we resolve them during

4719 * class.cs (Property): Revamp to use the convention of making fields readonly.

4768 and re-write the code in the actions to extract the specific and
4769 general catch clauses by being a little smart ;-)
4771 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
4772 Hooray, try and catch statements parse fine !

4817 (TypeContainer::events): New member to hold list of events.
4819 * cs-parser.jay (event_declaration): Implement actions.
4821 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
4823 * cs-parser.jay (dim_separators): Implement. Make it a string
4824 concatenating all the commas together, just as they appear.
4825 (opt_dim_separators): Modify accordingly
4826 (rank_specifiers): Update accordingly. Basically do the same
4827 thing - instead, collect the brackets here.
4828 (opt_rank_sepcifiers): Modify accordingly.
4829 (array_type): Modify to actually return the complete type string
4830 instead of ignoring the rank_specifiers.
4831 (expression_list): Implement to collect the expressions
4832 (variable_initializer): Implement. We make it a list of expressions
4833 essentially so that we can handle the array_initializer case neatly too.
4834 (variable_initializer_list): Implement.
4835 (array_initializer): Make it a list of variable_initializers
4836 (opt_array_initializer): Modify accordingly.
4838 * expression.cs (New::NType): Add enumeration to help us
4839 keep track of whether we have an object/delegate creation
4840 or an array creation.
4841 (New:NewType, New::Rank, New::Indices, New::Initializers): New
4842 members to hold data about array creation.
4843 (New:New): Modify to update NewType
4844 (New:New): New Overloaded contructor for the array creation
4847 * cs-parser.jay (array_creation_expression): Implement to call
4848 the overloaded New constructor.
4850 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
4852 * class.cs (TypeContainer::Constructors): Return member
4853 constructors instead of returning null.
4855 2001-08-26 Miguel de Icaza <miguel@ximian.com>
4857 * typemanager.cs (InitCoreTypes): Initialize the various core
4858 types after we have populated the type manager with the user
4859 defined types (this distinction will be important later while
4860 compiling corlib.dll)
4862 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
4863 on Expression Classification. Now all expressions have a method
4864 `Resolve' and a method `Emit'.
4866 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
4867 generation from working. Also add some temporary debugging
4870 2001-08-24 Miguel de Icaza <miguel@ximian.com>
4872 * codegen.cs: Lots of code generation pieces. This is only the
4873 beginning, will continue tomorrow with more touches of polish. We
4874 handle the fundamentals of if, while, do, for, return. Others are
4875 trickier and I need to start working on invocations soon.
4877 * gen-treedump.cs: Bug fix, use s.Increment here instead of
4880 * codegen.cs (EmitContext): New struct, used during code
4881 emission to keep a context. Most of the code generation will be
4884 * cs-parser.jay: Add embedded blocks to the list of statements of
4885 this block. So code generation proceeds in a top down fashion.
4887 2001-08-23 Miguel de Icaza <miguel@ximian.com>
4889 * statement.cs: Add support for multiple child blocks.
4891 2001-08-22 Miguel de Icaza <miguel@ximian.com>
4893 * codegen.cs (EmitCode): New function, will emit the code for a
4894 Block of code given a TypeContainer and its ILGenerator.
4896 * statement.cs (Block): Standard public readonly optimization.
4897 (Block::Block constructors): Link children.
4898 (Block::Child): Child Linker.
4899 (Block::EmitVariables): Emits IL variable declarations.
4901 * class.cs: Drop support for MethodGroups here, delay until
4903 (Method::): Applied the same simplification that I did before, and
4904 move from Properties to public readonly fields.
4905 (Method::ParameterTypes): Returns the parameter types for the
4906 function, and implements a cache that will be useful later when I
4907 do error checking and the semantic analysis on the methods is
4909 (Constructor::GetCallingConvention): Renamed from CallingConvetion
4910 and made a method, optional argument tells whether this is a class
4911 or a structure to apply the `has-this' bit.
4912 (Method::GetCallingConvention): Implement, returns the calling
4914 (Method::Define): Defines the type, a second pass is performed
4915 later to populate the methods.
4917 (Constructor::ParameterTypes): implement a cache similar to the
4918 one on Method::ParameterTypes, useful later when we do semantic
4921 (TypeContainer::EmitMethod): New method. Emits methods.
4923 * expression.cs: Removed MethodGroup class from here.
4925 * parameter.cs (Parameters::GetCallingConvention): new method.
4927 2001-08-21 Miguel de Icaza <miguel@ximian.com>
4929 * class.cs (TypeContainer::Populate): Drop RootContext from the
4932 (Constructor::CallingConvention): Returns the calling convention.
4933 (Constructor::ParameterTypes): Returns the constructor parameter
4936 (TypeContainer::AddConstructor): Keep track of default constructor
4937 and the default static constructor.
4939 (Constructor::) Another class that starts using `public readonly'
4940 instead of properties.
4942 (Constructor::IsDefault): Whether this is a default constructor.
4944 (Field::) use readonly public fields instead of properties also.
4946 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
4947 track of static constructors; If none is used, turn on
4948 BeforeFieldInit in the TypeAttributes.
4950 * cs-parser.jay (opt_argument_list): now the return can be null
4951 for the cases where there are no arguments.
4953 (constructor_declarator): If there is no implicit `base' or
4954 `this', then invoke the default parent constructor.
4956 * modifiers.cs (MethodAttr): New static function maps a set of
4957 modifiers flags into a MethodAttributes enum
4958 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
4959 MethodAttr, TypeAttr to represent the various mappings where the
4961 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
4963 2001-08-19 Miguel de Icaza <miguel@ximian.com>
4965 * parameter.cs (GetParameterInfo): Fix bug where there would be no
4968 * interface.cs (PopulateIndexer): Implemented the code generator
4969 for interface indexers.
4971 2001-08-17 Miguel de Icaza <miguel@ximian.com>
4973 * interface.cs (InterfaceMemberBase): Now we track the new status
4976 (PopulateProperty): Implement property population. Woohoo! Got
4977 Methods and Properties going today.
4979 Removed all the properties for interfaces, and replaced them with
4980 `public readonly' fields.
4982 2001-08-16 Miguel de Icaza <miguel@ximian.com>
4984 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
4985 initialize their hashtables/arraylists only when they are needed
4986 instead of doing this always.
4988 * parameter.cs: Handle refs and out parameters.
4990 * cs-parser.jay: Use an ArrayList to construct the arguments
4991 instead of the ParameterCollection, and then cast that to a
4994 * parameter.cs: Drop the use of ParameterCollection and use
4995 instead arrays of Parameters.
4997 (GetParameterInfo): Use the Type, not the Name when resolving
5000 2001-08-13 Miguel de Icaza <miguel@ximian.com>
5002 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
5003 and instead use public readonly fields.
5005 * class.cs: Put back walking code for type containers.
5007 2001-08-11 Miguel de Icaza <miguel@ximian.com>
5009 * class.cs (MakeConstant): Code to define constants.
5011 * rootcontext.cs (LookupType): New function. Used to locate types
5014 2001-08-08 Miguel de Icaza <miguel@ximian.com>
5016 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
5017 this System.Reflection code is. Kudos to Microsoft
5019 * typemanager.cs: Implement a type cache and avoid loading all
5020 types at boot time. Wrap in LookupType the internals. This made
5021 the compiler so much faster. Wow. I rule!
5023 * driver.cs: Make sure we always load mscorlib first (for
5024 debugging purposes, nothing really important).
5026 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
5027 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
5029 * rootcontext.cs: Lookup types on their namespace; Lookup types
5030 on namespaces that have been imported using the `using' keyword.
5032 * class.cs (TypeContainer::TypeAttr): Virtualize.
5033 (Class::TypeAttr): Return attributes suitable for this bad boy.
5034 (Struct::TypeAttr): ditto.
5035 Handle nested classes.
5036 (TypeContainer::) Remove all the type visiting code, it is now
5037 replaced with the rootcontext.cs code
5039 * rootcontext.cs (GetClassBases): Added support for structs.
5041 2001-08-06 Miguel de Icaza <miguel@ximian.com>
5043 * interface.cs, statement.cs, class.cs, parameter.cs,
5044 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
5045 Drop use of TypeRefs, and use strings instead.
5047 2001-08-04 Miguel de Icaza <miguel@ximian.com>
5051 * class.cs (Struct::Struct): set the SEALED flags after
5052 checking the modifiers.
5053 (TypeContainer::TypeAttr): new property, returns the
5054 TypeAttributes for a class.
5056 * cs-parser.jay (type_list): Oops, list production was creating a
5057 new list of base types.
5059 * rootcontext.cs (StdLib): New property.
5060 (GetInterfaceTypeByName): returns an interface by type name, and
5061 encapsulates error handling here.
5062 (GetInterfaces): simplified.
5063 (ResolveTree): Encapsulated all the tree resolution here.
5064 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
5067 * driver.cs: Add support for --nostdlib, to avoid loading the
5069 (Main): Do not put tree resolution here.
5071 * rootcontext.cs: Beginning of the class resolution.
5073 2001-08-03 Miguel de Icaza <miguel@ximian.com>
5075 * rootcontext.cs: Provide better error reporting.
5077 * cs-parser.jay (interface_base): set our $$ to be interfaces.
5079 * rootcontext.cs (CreateInterface): Handle the case where there
5080 are no parent interfaces.
5082 (CloseTypes): Routine to flush types at the end.
5083 (CreateInterface): Track types.
5084 (GetInterfaces): Returns an array of Types from the list of
5087 * typemanager.c (AddUserType): Mechanism to track user types (puts
5088 the type on the global type hash, and allows us to close it at the
5091 2001-08-02 Miguel de Icaza <miguel@ximian.com>
5093 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
5094 RecordInterface instead.
5096 * cs-parser.jay: Updated to reflect changes above.
5098 * decl.cs (Definition): Keep track of the TypeBuilder type that
5099 represents this type here. Not sure we will use it in the long
5100 run, but wont hurt for now.
5102 * driver.cs: Smaller changes to accomodate the new code.
5104 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
5107 * rootcontext.cs (CreateInterface): New method, used to create
5108 the System.TypeBuilder type for interfaces.
5109 (ResolveInterfaces): new entry point to resolve the interface
5111 (CodeGen): Property, used to keep track of the code generator.
5113 2001-07-26 Miguel de Icaza <miguel@ximian.com>
5115 * cs-parser.jay: Add a second production for delegate_declaration
5118 (enum_body): Put an opt_comma here instead of putting it on
5119 enum_body or enum_member_declarations so we can handle trailing
5120 commas on enumeration members. Gets rid of a shift/reduce.
5122 (type_list): Need a COMMA in the middle.
5124 (indexer_declaration): Tell tokenizer to recognize get/set
5126 * Remove old targets.
5128 * Re-add the parser target.
5130 2001-07-13 Simon Cozens <simon@simon-cozens.org>
5132 * cs-parser.jay: Add precendence rules for a number of operators
5133 ot reduce the number of shift/reduce conflicts in the grammar.
5135 2001-07-17 Miguel de Icaza <miguel@ximian.com>
5137 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
5140 Get rid of old crufty code.
5142 * rootcontext.cs: Use this to keep track of the parsed
5143 representation and the defined types available to the program.
5145 * gen-treedump.cs: adjust for new convention.
5147 * type.cs: Split out the type manager, and the assembly builder
5150 * typemanager.cs: the type manager will live here now.
5152 * cil-codegen.cs: And the code generator here.
5154 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
5156 * makefile: Fixed up for easy making.
5158 2001-07-13 Simon Cozens <simon@simon-cozens.org>
5160 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
5163 (unary_expression): Expand pre_increment_expression and
5164 post_decrement_expression to reduce a shift/reduce.
5166 2001-07-11 Simon Cozens
5168 * cs-tokenizer.cs: Hex numbers should begin with a 0.
5170 Improve allow_keyword_as_indent name.
5172 2001-06-19 Miguel de Icaza <miguel@ximian.com>
5174 * Adjustments for Beta2.
5176 2001-06-13 Miguel de Icaza <miguel@ximian.com>
5178 * decl.cs: Added `Define' abstract method.
5179 (InTransit): new property, used to catch recursive definitions.
5181 * interface.cs: Implement `Define'.
5183 * modifiers.cs: Map Modifiers.constants to
5184 System.Reflection.TypeAttribute flags.
5186 * class.cs: Keep track of types and user-defined types.
5187 (BuilderInit): New method for creating an assembly
5188 (ResolveType): New function to launch the resolution process, only
5189 used by interfaces for now.
5191 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
5192 that are inserted into the name space.
5194 2001-06-08 Miguel de Icaza <miguel@ximian.com>
5196 * ARGH. I have screwed up my tree so many times due to the use of
5197 rsync rather than using CVS. Going to fix this at once.
5199 * driver.cs: Objetify driver. Load assemblies, use assemblies to
5202 2001-06-07 Miguel de Icaza <miguel@ximian.com>
5204 * Experiment successful: Use System.Type rather that our own
5207 2001-05-25 Miguel de Icaza <miguel@ximian.com>
5209 * cs-parser.jay: Removed nsAliases from here.
5211 Use new namespaces, handle `using XXX;'
5213 * namespace.cs: Reimplemented namespace handling, use a recursive
5214 definition of the class. Now we can keep track of using clauses
5215 and catch invalid using clauses.
5217 2001-05-24 Miguel de Icaza <miguel@ximian.com>
5219 * gen-treedump.cs: Adapted for all the renaming.
5221 * expression.cs (Expression): this class now has a Type property
5222 which returns an expression Type.
5224 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
5225 `Type', as this has a different meaning now in the base
5227 2001-05-22 Miguel de Icaza <miguel@ximian.com>
5229 * interface.cs, class.cs: Removed from all the sources the
5230 references to signature computation, as we can not do method
5231 signature computation during the parsing time, as we are not
5232 trying to solve at that point distinguishing:
5236 void a (NS.Blah x) {}
5239 Which depending on the context might be valid or not, as we do not
5240 know if Blah is the same thing as NS.Blah at that point.
5242 * Redid everything so the code uses TypeRefs now instead of
5243 Types. TypeRefs are just temporary type placeholders, that need
5244 to be resolved. They initially have a pointer to a string and the
5245 current scope in which they are used. This is used later by the
5246 compiler to resolve the reference to an actual Type.
5248 * DeclSpace is no longer a CIR.Type, and neither are
5249 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
5250 are all DeclSpaces, but no Types.
5252 * type.cs (TypeRefManager): This implements the TypeRef manager,
5253 which keeps track of all the types that need to be resolved after
5254 the parsing has finished.
5256 2001-05-13 Miguel de Icaza <miguel@ximian.com>
5258 * ARGH. We are going to have to store `foreach' as a class rather
5259 than resolving it, as we need to verify error 1579 after name
5260 resolution. *OR* we could keep a flag that says `This request to
5261 IEnumerator comes from a foreach statement' which we can then use
5262 to generate the error.
5264 2001-05-10 Miguel de Icaza <miguel@ximian.com>
5266 * class.cs (TypeContainer.AddMethod): we now add methods to the
5267 MethodGroup instead of the method hashtable.
5269 * expression.cs: Add MethodGroup abstraction, which gets us one
5270 step closer to the specification in the way we handle method
5273 * cs-parser.jay (primary_expression): qualified_identifier now
5274 tried to match up an identifier to a local variable reference or
5275 to a parameter reference.
5277 current_local_parameters is now a parser global variable that
5278 points to the current parameters for the block, used during name
5281 (property_declaration): Now creates an implicit `value' argument to
5284 2001-05-09 Miguel de Icaza <miguel@ximian.com>
5286 * parameter.cs: Do not use `param' arguments as part of the
5287 signature, per the spec.
5289 2001-05-08 Miguel de Icaza <miguel@ximian.com>
5291 * decl.cs: Base class for classes, structs and interfaces. This
5292 is the "Declaration Space"
5294 * cs-parser.jay: Use CheckDef for checking declaration errors
5295 instead of having one on each function.
5297 * class.cs: Factor out some code for handling error handling in
5298 accordance to the "Declarations" section in the "Basic Concepts"
5299 chapter in the ECMA C# spec.
5301 * interface.cs: Make all interface member classes derive from
5302 InterfaceMemberBase.
5304 2001-05-07 Miguel de Icaza <miguel@ximian.com>
5306 * Many things: all interfaces are parsed and generated in
5307 gen-treedump. Support for member variables, constructors,
5308 destructors, properties, constants is there.
5310 Beginning of the IL backend, but very little done, just there for
5313 2001-04-29 Miguel de Icaza <miguel@ximian.com>
5315 * cs-parser.jay: Fix labeled statement.
5317 * cs-tokenizer.cs (escape): Escape " and ' always.
5318 ref_line, ref_name: keep track of the line/filename as instructed
5319 by #line by the compiler.
5322 2001-04-27 Miguel de Icaza <miguel@ximian.com>
5324 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
5325 to match the values in System.CodeDOM.
5327 Divid renamed to Divide.
5329 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
5331 (Statements.set): remove.
5333 * System.CodeDOM/CodeCatchClause.cs: always have a valid
5336 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
5337 falseStatements always have valid values.
5339 * cs-parser.jay: Use System.CodeDOM now.
