1 2002-07-11 Miguel de Icaza <miguel@ximian.com>
3 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
5 (LoadAssembly): Do not add the dll if it is already specified
7 (MainDriver): Add the System directory to the link path at the end,
8 after all the other -L arguments.
10 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
11 wrong opcode for loading bytes and bools (ldelem.i1 instead of
12 ldelem.u1) and using the opposite for sbytes.
14 This fixes Digger, and we can finally run it.
16 * driver.cs (UnixParseOption): Move the option parsing here.
17 (CSCParseOption): Implement CSC-like parsing of options.
19 We now support both modes of operation, the old Unix way, and the
20 new CSC-like way. This should help those who wanted to make cross
23 The only thing broken is that /r:, /reference: and /lib: are not
24 implemented, because I want to make those have the same semantics
25 as the CSC compiler has, and kill once and for all the confussion
26 around this. Will be doing this tomorrow.
28 * statement.cs (Unsafe.Resolve): The state is checked during
29 resolve, not emit, so we have to set the flags for IsUnsfe here.
31 2002-07-10 Miguel de Icaza <miguel@ximian.com>
33 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
34 not catch the Error_ObjectRefRequired in SimpleName (as it is
35 possible to have a class/instance variable name that later gets
36 deambiguated), we have to check this here.
38 2002-07-10 Ravi Pratap <ravi@ximian.com>
40 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
41 make static and put into Expression.
43 (Event.Define): Register the private field of the event with the
44 TypeManager so that GetFieldFromEvent can get at it.
46 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
47 keep track of the private field associated with an event which
50 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
53 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
55 2002-07-10 Miguel de Icaza <miguel@ximian.com>
57 * expression.cs (Binary.EmitBranchable): this routine emits the
58 Binary expression in a branchable context. This basically means:
59 we need to branch somewhere, not just get the value on the stack.
61 This works together with Statement.EmitBoolExpression.
63 * statement.cs (Statement.EmitBoolExpression): Use
66 2002-07-09 Miguel de Icaza <miguel@ximian.com>
68 * statement.cs (For): Reduce the number of jumps in loops.
70 (For): Implement loop inversion for the For statement.
72 (Break): We can be breaking out of a Try/Catch controlled section
73 (foreach might have an implicit try/catch clause), so we need to
74 use Leave instead of Br.
76 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
77 now). If the instace expression supports IMemoryLocation, we use
78 the AddressOf method from the IMemoryLocation to extract the
79 address instead of emitting the instance.
81 This showed up with `This', as we were emitting the instance
82 always (Emit) instead of the Address of This. Particularly
83 interesting when This is a value type, as we dont want the Emit
84 effect (which was to load the object).
86 2002-07-08 Miguel de Icaza <miguel@ximian.com>
88 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
90 * statement.cs (Checked): Set the CheckedState during the resolve
91 process too, as the ConvCast operations track the checked state on
92 the resolve process, and not emit.
94 * cs-parser.jay (namespace_member_declaration): Flag that we have
95 found a declaration when we do. This is used to flag error 1529
97 * driver.cs: Report ok when we display the help only.
99 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
101 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
103 2002-07-04 Miguel de Icaza <miguel@ximian.com>
105 * cs-tokenizer.cs (define): We also have to track locally the
106 defines. AllDefines is just used for the Conditional Attribute,
107 but we also need the local defines for the current source code.
109 2002-07-03 Miguel de Icaza <miguel@ximian.com>
111 * statement.cs (While, For, Do): These loops can exit through a
112 Break statement, use this information to tell whether the
113 statement is the last piece of code.
115 (Break): Flag that we break.
117 * codegen.cs (EmitContexts): New `Breaks' state variable.
119 2002-07-03 Martin Baulig <martin@gnome.org>
121 * class.cs (TypeContainer.MethodModifiersValid): Allow override
122 modifiers in method declarations in structs. Otherwise, you won't
123 be able to override things like Object.Equals().
125 2002-07-02 Miguel de Icaza <miguel@ximian.com>
127 * class.cs (Method, Property, Indexer): Do not allow the public
128 modifier to be used in explicit interface implementations.
130 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
131 override modifiers in method declarations in structs
133 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
135 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
136 integer or real overflow, report an error
138 2002-07-02 Martin Baulig <martin@gnome.org>
140 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
141 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
142 to tell the runtime about our newly created System.Object and
143 System.ValueType types.
145 2002-07-02 Miguel de Icaza <miguel@ximian.com>
147 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
148 struct instead of Ldarg/Starg.
150 2002-07-02 Martin Baulig <martin@gnome.org>
152 * expression.cs (Indirection.Indirection): Call
153 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
155 2002-07-02 Martin Baulig <martin@gnome.org>
157 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
158 ValueType, call TypeManager.TypeToCoreType() on it.
159 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
160 the OpCodes.Newarr argument.
162 2002-07-02 Martin Baulig <martin@gnome.org>
164 * expression.cs (Invocation.EmitCall): When compiling corlib,
165 replace all calls to the system's System.Array type to calls to
166 the newly created one.
168 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
169 System.Array methods.
170 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
171 from the system's System.Array type which must be replaced.
173 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
175 * typemanager.cs: load unverifiable_code_ctor so we can build
176 corlib using the correct type. Avoid using GetTypeCode() with
178 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
179 TypeManager.object_type to allow building corlib.
181 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
183 * ecore.cs: handle System.Enum separately in LoadFromPtr().
185 2002-07-01 Martin Baulig <martin@gnome.org>
187 * class.cs: Make the last change actually work, we need to check
188 whether `ifaces != null' to avoid a crash.
190 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
192 * class.cs: when we build structs without fields that implement
193 interfaces, we need to add the interfaces separately, since there is
194 no API to both set the size and add the interfaces at type creation
197 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
199 * expression.cs: the dimension arguments to the array constructors
200 need to be converted if they are a long.
202 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
204 * class.cs: don't emit ldarg.0 if there is no parent constructor
205 (fixes showstopper for corlib).
207 2002-06-29 Martin Baulig <martin@gnome.org>
209 MCS now compiles corlib on GNU/Linux :-)
211 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
212 ie. check for MethodImplOptions.InternalCall.
214 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
215 and TypeManager.attribute_type are null, so we must explicitly check
216 whether parent is not null to find out whether it's an attribute type.
217 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
218 and SetBuilder, not only if the property is neither abstract nor external.
219 This is necessary to set the MethodImplOptions on the accessor methods.
220 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
221 SetBuilder, see Property.Emit().
223 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
224 populate "System.Object", "System.ValueType" and "System.Attribute" since
225 they've already been populated from BootCorlib_PopulateCoreTypes().
227 2002-06-29 Martin Baulig <martin@gnome.org>
229 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
230 is the NullLiteral, we also need to make sure that target_type is not
233 2002-06-29 Martin Baulig <martin@gnome.org>
235 * rootcontext.cs (RootContext.ResolveCore): We must initialize
236 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
237 before calling BootstrapCorlib_ResolveDelegate ().
239 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
241 * statement.cs: fixed build-breaker. All tests passed ok.
243 2002-06-27 Martin Baulig <martin@gnome.org>
245 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
246 for System.Decimal when compiling corlib.
248 2002-06-27 Martin Baulig <martin@gnome.org>
250 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
251 switch blocks which contain nothing but a default clause.
253 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
255 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
257 2002-06-27 Martin Baulig <martin@gnome.org>
259 * ecore.cs (PropertyExpr.PropertyExpr): Call
260 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
262 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
263 is already a TypeBuilder.
265 2002-06-27 Martin Baulig <martin@gnome.org>
267 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
268 `target_type == TypeManager.array_type', not IsAssignableFrom() in
269 the "from an array-type to System.Array" case. This makes it work
270 when compiling corlib.
272 2002-06-27 Martin Baulig <martin@gnome.org>
274 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
275 non-static PropertyExpr, set its InstanceExpression. This makes
276 the `ICollection.Count' property work in System/Array.cs.
278 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
280 * driver.cs: Made error handling more consistent. Errors now
281 tracked by Report class, so many methods which used to return int
282 now return void. Main() now prints success/failure and
283 errors/warnings message.
285 Renamed '--probe' compiler argument to '--expect-error'. Removed
286 the magic number return values (123 and 124). Now, if the
287 expected error occurs, the compiler exits with success (exit value
288 0). If the compilation completes without seeing that particular
289 error, the compiler exits with failure (exit value 1). The
290 makefile in mcs/errors has been changed to handle the new behaviour.
292 * report.cs: Made 'expected error' number a property and renamed
293 it from 'Probe' to 'ExpectedError'.
295 * genericparser.cs: Removed error handling support, since it is
296 now all done by Report class.
298 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
299 class, so parse() no longer returns an int.
301 * namespace.cs: Use Report.Error instead of GenericParser.error
303 2002-06-22 Miguel de Icaza <miguel@ximian.com>
305 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
306 TypeContainer.AddOperator): At the front of the list put the
307 explicit implementations, so they get resolved/defined first.
309 2002-06-21 Miguel de Icaza <miguel@ximian.com>
311 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
312 interface type is implemented by this TypeContainer. Used during
313 explicit interface implementation.
315 (Property.Define, Indexer.Define, Method.Define): Validate that
316 the given interface in the explicit implementation is one of the
317 base classes for the containing type.
319 Also if we are explicitly implementing an interface, but there is
320 no match in the pending implementation table, report an error.
322 (Property.Define): Only define the property if we are
323 not explicitly implementing a property from an interface. Use the
324 correct name also for those properties (the same CSC uses,
325 although that is really not needed).
327 (Property.Emit): Do not emit attributes for explicitly implemented
328 properties, as there is no TypeBuilder.
330 (Indexer.Emit): ditto.
332 Hiding then means that we do not really *implement* a pending
333 implementation, which makes code fail.
335 2002-06-22 Martin Baulig <martin@gnome.org>
337 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
338 the return value of Object.GetType(). [FIXME: we need to do this whenever
339 we get a type back from the reflection library].
341 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
343 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
345 2002-06-20 Miguel de Icaza <miguel@ximian.com>
347 * attribute.cs: Return null if we can not look up the type.
349 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
350 the interface types found.
352 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
353 interface types found.
355 * typemanager.cs (GetInterfaces): Make this routine returns alll
356 the interfaces and work around the lame differences between
357 System.Type and System.Reflection.Emit.TypeBuilder in the results
358 result for GetInterfaces.
360 (ExpandInterfaces): Given an array of interface types, expand and
361 eliminate repeated ocurrences of an interface. This expands in
362 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
365 2002-06-21 Martin Baulig <martin@gnome.org>
367 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
370 2002-06-21 Martin Baulig <martin@gnome.org>
372 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
373 and called with one of the core types, return the corresponding typebuilder for
376 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
379 2002-06-21 Martin Baulig <martin@gnome.org>
381 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
382 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
383 (Expression.ConvertReferenceExplicit): Likewise.
385 * expression.cs (ElementAccess.DoResolve): Likewise.
386 (ElementAccess.DoResolveLValue): Likewise.
388 2002-06-10 Martin Baulig <martin@gnome.org>
390 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
391 add the "value" parameter to the parameter list.
393 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
396 2002-06-19 Miguel de Icaza <miguel@ximian.com>
398 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
399 the argument to an int, uint, long or ulong, per the spec. Also
400 catch negative constants in array creation.
402 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
404 * class.cs: do not allow the same interface to appear twice in
407 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
409 * ecore.cs: don't use ldlen with System.Array.
411 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
413 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
415 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
417 * modifiers.cs: produce correct field attributes for protected
418 internal. Easy fix so miguel can work on ther harder stuff:-)
420 2002-06-18 Miguel de Icaza <miguel@ximian.com>
422 * pending.cs: New file. Move the code from class.cs here.
423 Support clearning the pending flag for all methods (when not doing
424 explicit interface implementation).
426 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
428 * rootcontext.cs: added a couple more types needed to bootstrap.
430 2002-06-17 Miguel de Icaza <miguel@ximian.com>
432 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
433 constructor in the type, instead of any constructor in the type
434 hierarchy. Thanks to Paolo for finding this bug (it showed up as
435 a bug in the Mono runtime when applying the params attribute).
437 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
438 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
440 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
442 * expression.cs (Unary.ResolveOperator): Use TypeManager
445 2002-06-13 Ravi Pratap <ravi@ximian.com>
447 * cs-parser.jay (enum_member_declaration): Pass in the attributes
450 * enum.cs (AddEnumMember): Add support to store the attributes associated
451 with each member too.
453 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
454 field builders too - this takes care of the enum member case.
456 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
458 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
459 address-of operator on both value types and pointers.
461 2002-06-10 Martin Baulig <martin@gnome.org>
463 * interface.cs (Interface.PopulateIndexer): Add the indexer's
464 PropertyBuilder to the `property_builders' list.
466 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
467 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
468 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
469 find any indexers which are inherited from an interface.
471 2002-06-09 Martin Baulig <martin@gnome.org>
473 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
474 the same type as the constant if necessary. There's also a test-130.cs
477 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
479 * typemanager.cs (TypeManager.ChangeType): Previously known as
480 Enum.ChangeEnumType().
482 2002-06-09 Martin Baulig <martin@gnome.org>
484 * expression.cs (Cast.TryReduce): Added support for consts.
486 2002-06-08 Ravi Pratap <ravi@ximian.com>
488 * class.cs (Accessor): Hold attributes information so we can pass
491 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
492 Modify to pass in attributes attached to the methods.
494 (add_accessor_declaration, remove_accessor_declaration): Ditto.
496 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
497 to handle the Accessor kind :-)
499 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
501 2002-06-08 Martin Baulig <martin@gnome.org>
503 * expression.cs (Unary.TryReduceNegative): Added support for
506 2002-06-08 Martin Baulig <martin@gnome.org>
508 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
509 name can't be found in the `defined_names' - the caller will do a
510 MemberLookup in this case and thus find methods in System.Enum
511 such as Enum.IsDefined().
513 2002-06-08 Martin Baulig <martin@gnome.org>
515 * enum.cs (Enum.ChangeEnumType): This is a custom version of
516 Convert.ChangeType() which works with TypeBuilder created types.
517 (Enum.LookupEnumValue, Enum.Define): Use it here.
519 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
520 `TypeBuilder.BaseType != null' check.
521 (TypeContainer.FindMembers): Only lookup parent members if we
522 actually have a parent.
523 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
524 (ConstructorInitializer.Resolve): Likewise.
526 * interface.cs (Interface.FindMembers): Added
527 `TypeBuilder.BaseType != null' check.
529 * rootcontext.cs (RootContext.ResolveCore): Added
530 "System.Runtime.CompilerServices.IndexerNameAttribute" to
531 classes_second_stage.
533 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
534 debug_type and trace_type when compiling with --nostdlib.
536 2002-06-07 Martin Baulig <martin@gnome.org>
538 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
539 (AddField): Set it to true when adding a non-static field.
540 (DefineType): Use `have_nonstatic_fields' to find out whether we
541 have non-static fields, not `Fields != null'.
543 2002-06-02 Miguel de Icaza <miguel@ximian.com>
545 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
546 dereferencing a null on the static-field code path)
548 2002-05-30 Martin Baulig <martin@gnome.org>
550 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
551 to take command line arguments. Use reflection to call the new
552 custom `Initialize' function on the symbol writer and pass it the
553 command line arguments.
555 * driver.cs (--debug-args): New command line argument to pass command
556 line arguments to the symbol writer.
558 2002-05-28 Miguel de Icaza <miguel@ximian.com>
560 * assign.cs (DoResolve): Forgot to do the implicit conversion to
561 the target type for indexers and properties. Thanks to Joe for
564 2002-05-27 Miguel de Icaza <miguel@ximian.com>
566 * typemanager.cs (MethodFlags): returns the method flags
567 (Obsolete/ShouldIgnore) that control warning emission and whether
568 the invocation should be made, or ignored.
570 * expression.cs (Invocation.Emit): Remove previous hack, we should
571 not do this on matching a base type, we should do this based on an attribute
573 Only emit calls to System.Diagnostics.Debug and
574 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
577 * rootcontext.cs: Global settings for tracing and debugging.
579 * cs-tokenizer.cs (define): New utility function to track
580 defines. Set the global settings for TRACE and DEBUG if found.
582 2002-05-25 Ravi Pratap <ravi@ximian.com>
584 * interface.cs (Populate*): Pass in the TypeContainer as well as
585 the DeclSpace as parameters so that we can create EmitContexts and
586 then use that to apply attributes etc.
588 (PopulateMethod, PopulateEvent, PopulateProperty)
589 (PopulateIndexer): Apply attributes everywhere.
591 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
594 (ApplyAttributes): Update accordingly.
596 We now apply interface attributes for all members too.
598 2002-05-26 Miguel de Icaza <miguel@ximian.com>
600 * class.cs (Indexer.Define); Correctly check if we are explicit
601 implementation (instead of checking the Name for a ".", we
602 directly look up if the InterfaceType was specified).
604 Delay the creation of the PropertyBuilder.
606 Only create the PropertyBuilder if we are not an explicit
607 interface implementation. This means that explicit interface
608 implementation members do not participate in regular function
609 lookups, and hence fixes another major ambiguity problem in
610 overload resolution (that was the visible effect).
612 (DefineMethod): Return whether we are doing an interface
615 * typemanager.cs: Temporary hack until we get attributes in
616 interfaces (Ravi is working on that) and we get IndexerName
617 support in interfaces.
619 * interface.cs: Register the indexers as properties.
621 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
622 warning, I have verified that this is a bug in the .NET runtime
623 (JavaScript suffers of the same problem).
625 * typemanager.cs (MemberLookup): When looking up members for
626 interfaces, the parent of an interface is the implicit
627 System.Object (so we succeed in searches of Object methods in an
628 interface method invocation. Example: IEnumerable x; x.ToString
631 2002-05-25 Miguel de Icaza <miguel@ximian.com>
633 * class.cs (Event): Events should also register if they do
634 implement the methods that an interface requires.
636 * typemanager.cs (MemberLookup); use the new GetInterfaces
639 (GetInterfaces): The code used to lookup interfaces for a type is
640 used in more than one place, factor it here.
642 * driver.cs: Track the errors at the bottom of the file, we kept
645 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
646 instance if the method we are calling is static!
648 2002-05-24 Miguel de Icaza <miguel@ximian.com>
650 * attribute.cs (ApplyAttributes): Make this function filter out
651 the IndexerName attribute (as that attribute in reality is never
652 applied) and return the string constant for the IndexerName
655 * class.cs (TypeContainer.Emit): Validate that all the indexers
656 have the same IndexerName attribute, and if so, set the
657 DefaultName attribute on the class.
659 * typemanager.cs: The return value might contain other stuff (not
660 only methods). For instance, consider a method with an "Item"
661 property and an Item method.
663 * class.cs: If there is a problem with the parameter types,
666 2002-05-24 Ravi Pratap <ravi@ximian.com>
668 * ecore.cs (ImplicitConversionExists): Wrapper function which also
669 looks at user defined conversion after making a call to
670 StandardConversionExists - we need this for overload resolution.
672 * expression.cs : Update accordingly the various method calls.
674 This fixes 2 bugs filed against implicit user defined conversions
676 2002-05-22 Miguel de Icaza <miguel@ximian.com>
678 * statement.cs: Track the result of the assignment.
680 2002-05-21 Miguel de Icaza <miguel@ximian.com>
682 * expression.cs (MemberAccess): Improved error reporting for
683 inaccessible members.
685 2002-05-22 Martin Baulig <martin@gnome.org>
687 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
688 itself with debugging support.
690 2002-05-22 Martin Baulig <martin@gnome.org>
692 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
693 Removed, this isn't needed anymore.
695 2002-05-20 Martin Baulig <martin@gnome.org>
697 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
698 be underlying type for an enum.
700 2002-05-20 Miguel de Icaza <miguel@ximian.com>
702 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
703 that splits out the loading of just the core types.
705 * rootcontext.cs (ResolveCore): Split the struct resolution in
706 two, so we can load the enumeration underlying types before any
709 * expression.cs (Is): Bandaid until we fix properly Switch (see
710 bug #24985 for details).
712 * typemanager.cs (ImplementsInterface): The hashtable will contain
713 a null if there are no interfaces implemented.
715 2002-05-18 Miguel de Icaza <miguel@ximian.com>
717 * cs-parser.jay (indexer_declarator): It is fine to have array
720 2002-05-17 Miguel de Icaza <miguel@ximian.com>
722 * typemanager.cs: (RegisterBuilder): New function used to register
723 TypeBuilders that implement interfaces. Since
724 TypeBuilder.GetInterfaces (as usual) does not work with lame
726 (AddUserType): register interfaces.
728 (ImplementsInterface): Use the builder_to_ifaces hash if we are
729 dealing with TypeBuilder. Also, arrays are showing up as
730 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
731 methods can not be invoked on them!
733 * ecore.cs (ExplicitReferenceConversionExists): Made public.
734 (ImplicitReferenceConversionExists): Split out from
735 StandardConversionExists.
737 * expression.cs (As): We were only implementing one of the three
738 cases for the as operator. We now implement them all.
739 (Is): Implement the various other cases for Is as well.
741 * typemanager.cs (CACHE): New define used to control if we want or
742 not the FindMembers cache. Seems to have a negative impact on
743 performance currently
745 (MemberLookup): Nested types have full acess to
746 enclosing type members
748 Remove code that coped with instance/static returns for events, we
749 now catch this in RealFindMembers.
751 (RealFindMembers): only perform static lookup if the instance
752 lookup did not return a type or an event.
754 2002-05-17 Miguel de Icaza <miguel@ximian.com>
756 * assign.cs (CompoundAssign): We pass more semantic information
757 now to Compound Assignments than we did before: now we have all
758 the information at hand, and now we resolve the target *before* we
759 do the expression expansion, which allows the "CacheValue" method
760 to have the effect we intended (before, a [x] += 1 would generate
761 two differen ArrayAccess expressions from the ElementAccess,
762 during the resolution process).
764 (CompoundAssign.DoResolve): Resolve target and original_source here.
766 2002-05-16 Miguel de Icaza <miguel@ximian.com>
768 * expression.cs (ArrayAccess): dropped debugging information.
770 * typemanager.cs: Small bug fix: I was always returning i_members,
771 instead of one of i_members or s_members (depending on which had
774 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
775 method is invoked before any code generation takes place, and it
776 is a mechanism to inform that the expression will be invoked more
777 than once, and that the method should use temporary values to
778 avoid having side effects
780 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
782 * ecore.cs (Expression.CacheTemporaries): Provide empty default
785 * expression.cs (Indirection, ArrayAccess): Add support for
786 CacheTemporaries in these two bad boys.
788 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
790 (StoreFromPtr): Handle stobj as well.
792 * expression.cs (UnaryMutator): Share more code.
794 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
795 down: I was not tracking the Filter function as well, which
796 was affecting the results of the cache.
798 2002-05-15 Miguel de Icaza <miguel@ximian.com>
800 * attribute.cs: Remove the hack to handle the CharSet property on
803 2002-05-14 Miguel de Icaza <miguel@ximian.com>
805 * attribute.cs (DoResolve): More uglyness, we now only try to
806 resolve the attribute partially, to extract the CharSet
807 information (only if we are a StructLayout attribute). Otherwise
809 (GetExtraTypeInfo): Add some code to conditionally kill in the
810 future this. I am more and more convinced that the .NET
811 framework has special code to handle the attribute setting on
814 * expression.cs (IsParamsMethodApplicable): Revert my previous
815 foreach change here, it was wrong.
817 2002-05-13 Miguel de Icaza <miguel@ximian.com>
819 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
820 (pp_expr): do not abort on unknown input, just return.
821 (eval): abort if there are pending chars.
823 * attribute.cs (Attribute.Resolve): Positional parameters are
824 optional. Deal with that case.
826 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
827 the Ansi/Unicode/Auto information for the type.
829 (TypeContainer.DefineType): instantiate the EmitContext here, as
830 we will be using it during the type definition (to resolve
831 attributes) and during the emit phase.
833 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
834 to pull type information out of the attributes
836 (Attribute.Resolve): track the constructor builder, and allow for
837 multiple invocations (structs and classes will use this).
839 * ecore.cs (MemberLookupFinal): new version with all the
840 parameters customizable.
842 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
843 constructors. Return if the result value is null (as the error
844 would have been flagged already by MemberLookupFinal)
846 Do not allow instances of abstract classes or interfaces to be
849 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
850 We have to compare the assembly property here when dealing with
851 FamANDAssem and Assembly access modifiers, because we might be
852 creating an assembly from *modules* (that means that we are not
853 getting TypeBuilders for types defined in other modules that are
854 part of this assembly).
856 (Method.Emit): If the method is marked abstract and has a body,
859 (TypeContainer.DefineMembers): If both the defined member and the
860 parent name match are methods, then do not emit any warnings: let
861 the Method.Define routine take care of flagging warnings. But if
862 there is a mismatch (method overrides something else, or method is
863 overriwritten by something, then emit warning).
865 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
866 set to null, this means `do not check for the return type on the
869 (Method.Define): set the return type for the method signature to
870 null, so that we get methods with the same name and parameters and
871 different return types. This is used to flag warning 114 (you are
872 hiding a method, and you probably want to use the new/override
875 * typemanager.cs (MemberLookup): Implemented proper access
876 control, closing a long standing set of bug reports. The problem
877 was that the Framework only has two bits: Public and NonPublic,
878 and NonPublic includes private and protected methods, but we need
879 to enforce the FamANDAssem, FamOrAssem and Family.
881 2002-05-11 Miguel de Icaza <miguel@ximian.com>
883 * statement.cs (GotoCase): Return true: Ammounts to giving up
884 knowledge on whether we return or not, and letting the other case
885 be responsible for it.
887 2002-05-10 Miguel de Icaza <miguel@ximian.com>
889 * driver.cs: Do not load directories for each file processed, only
890 do it if there is a pattern.
892 * ecore.cs: Report readonly assigns here as well, as we might have
893 been resolved only by MemberAccess.
895 (SimpleName.SimpleNameResolve): Also be useful for LValue
896 resolution. We need this to propagate assign to local readonly variables
898 * typemanager.cs: Use a ptrhashtable for the criteria, because we
899 do not want to reuse potential criteria memory.
901 * class.cs (MyEventBuilder): Set reflected_type;
903 * ecore.cs (Constantify): Added support for constifying bools.
905 (RootContext.LookupType): Added a cache for values looked up in
906 the declaration space.
908 * typemanager.cs (FindMembers): Now is a front-end to
909 RealFindMembers, and provides a two-level hashtable-based cache to
912 15% performance improvement: from 22.5 to 19.2 seconds.
914 * expression.cs (IsParamsMethodApplicable): use foreach.
915 (Invocation.DoResolve): ditto.
916 (New.DoResolve): ditto.
917 (ArrayCreation.DoResolve): ditto.
919 * ecore.cs (FindMostEncompassingType): use foreach.
921 * delegate.cs (NewDelegate.DoResolve): Use foreach
923 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
924 (RemoveMethods): use foreach.
926 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
927 nested foreach statements instead of for, and also break out of
928 the inner loop once a match is found.
930 (Invocation.OverloadResolve): Use foreach, simplify the code.
932 2002-05-08 Miguel de Icaza <miguel@ximian.com>
934 * cfold.cs (BinaryFold): During an enumeration evaluation context,
935 we actually unwrap the expression to allow for extra information
938 * expression.cs: Use Shr_Un on unsigned operations.
940 2002-05-08 Ravi Pratap <ravi@ximian.com>
942 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
943 applicable operators was not being considered correctly. This closes
944 the bug Miguel reported.
946 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
948 * attribute.cs: check that the type derives from System.Attribute
949 and report the correct error in that case (moved the duplicate code to
950 its own method, too).
952 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
954 * attribute.cs: lookup attribute type name as the spec says: first the
955 bare attribute name and then name + "Attribute" (nant compiles with
958 2002-05-07 Miguel de Icaza <miguel@ximian.com>
960 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
961 Because of the way we parse things, we should try to see if a
962 UIntConstant can fit in an integer.
964 2002-05-07 Ravi Pratap <ravi@ximian.com>
966 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
967 when we are in an explicit context.
969 (ConvertReferenceExplicit): When converting from Iface type S to Class
970 T make sure the rules are implemented as an OR.
972 * parameter.cs (ParameterType): Make it a property for now although the
973 purpose really isn't anything immediate.
975 * expression.cs (Is*Applicable): Do better checking on the parameter type
976 of a ref/out parameter. The ones from the system assemblies are already
977 marked with the correct type so we don't need to do any correction.
979 * ecore.cs (StandardConversionExists): Conversion from Interface types to
980 the object type is standard too so include that.
982 2002-05-06 Miguel de Icaza <miguel@ximian.com>
984 * ecore.cs (StandardConversionExists): Augment with missing code:
985 deal with IntConstant, LongConstants and Enumerations.
987 * assign.cs: Report the error, instead of failing silently
989 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
990 typecontainer that they are declared, because the
991 typecontainer/namespace will have the list of using clauses that
994 Assembly Attributes were escaping the normal registration
997 (EmitCode): Apply attributes within an EmitContext that represents
998 the container they were declared on.
1000 * cs-parser.jay: Track bases for structs. How did I get this wrong?
1002 2002-05-06 Ravi Pratap <ravi@ximian.com>
1004 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
1005 Revamp completely - make much cleaner as we now operate only
1008 (FindMostSpecificSource, FindMostSpecificTarget): New methods
1009 to implement the logic detailed in the spec more correctly.
1011 (UserDefinedConversion): Update accordingly.
1013 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1015 * statement.cs: Return flow analysis information up.
1017 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
1020 (token): Do not consume an extra character before calling
1023 2002-05-06 Piers Haken <piersh@friskit.com>
1025 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
1027 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1029 * class.cs (Constructor.Emit): Set the IsStatic flag in the
1030 EmitContext during the instance constructor initializer
1031 resolution, to stop access to instance variables.
1033 This is mandated by the spec, last paragraph of the `constructor
1034 initializers' section.
1036 2002-05-05 Miguel de Icaza <miguel@ximian.com>
1038 * cs-parser.jay, class.cs (Accessor): new class used to represent
1039 an accessor (get or set). In the past we used `null' to represent
1040 a missing accessor. But this is ambiguous because there was no
1041 way to tell in abstract indexers/properties if one of them was
1044 Now there is a way of addressing that.
1046 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
1047 instead of FindMembers.
1049 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
1050 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
1052 * attribute.cs: Treat indexers and properties as the same in terms
1053 of applying attributes
1055 * ecore.cs (FindMostEncompassedType): Use statically initialized
1056 EmptyExpressions()s like we do elsewhere to avoid creating useless
1057 objects (and we take this out of the tight loop).
1059 (GetConversionOperators): Move the code to extract the actual
1060 operators to a separate routine to clean things up.
1062 2002-05-04 Miguel de Icaza <miguel@ximian.com>
1064 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
1065 events are always registered FieldBuilders.
1067 * class.cs (FieldBase): New class shared by Fields
1069 * delegate.cs: If we are a toplevel delegate, use our full name.
1070 If we are a nested delegate, then only use our tail name.
1072 2002-05-02 Ravi Pratap <ravi@ximian.com>
1074 * expression.cs (IsApplicable): Ensure that we add the "&" to
1075 ref/out types before comparing it with the type of the argument.
1077 (IsParamsMethodApplicable): Ditto.
1079 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
1082 * delegate.cs : Handle the case when we have more than one applicable
1083 method. Flag an error only when we finish checking all.
1085 2002-05-02 Miguel de Icaza <miguel@ximian.com>
1087 * expression.cs: Add support for boolean static initializers.
1089 2002-05-01 Miguel de Icaza <miguel@ximian.com>
1091 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
1093 * parameter.cs (ComputeParameterTypes,
1094 ComputeAndDefineParameterTypes): Better error handling: now we
1095 clear the `types' cache if we fail during any of the type lookups.
1096 We also return the status code correctly to our caller
1098 * delegate.cs: If we fail to define a delegate, abort the extra
1101 * expression.cs (Binary.ResolveOperator): for
1102 operator==(object,object) and operator !=(object, object) we also
1103 have to verify that there is an implicit conversion from one to
1106 (ArrayAccess.DoResolve): Array Access can operate on
1109 2002-04-30 Miguel de Icaza <miguel@ximian.com>
1111 * assign.cs (CompoundAssign): A new class used as a "flag" that
1112 the assignment actually is happening as part of a compound
1113 assignment operator.
1115 During compound assignment, a few new rules exist to enable things
1122 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
1123 to the type of x) if y is implicitly convertible to the type of x,
1124 and the operator is a builtin operator and the return type of the
1125 operator is explicitly convertible to the type of x.
1127 * rootcontext.cs: Reset warning level to 2. 4 catches various
1128 "interesting" features in mcs, we must clean this up at some
1129 point, but currently am trying to kill other bugs ;-)
1131 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
1132 in container classes as well.
1134 * expression.cs (Binary.ResolveOperator): Handle string case
1135 before anything else (as operator overloading does emit an error
1136 before doing anything else).
1138 This code could go away when we move to a table driven model, but
1139 i could not come up with a good plan last night.
1141 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
1143 * typemanager.cs (CSharpName): reimplementation using regex.
1144 * class.cs: added null check for fields in Emit
1145 * rootcontext.cs: set warninglevel to 4
1147 2002-04-29 Miguel de Icaza <miguel@ximian.com>
1149 * typemanager.cs (CSharpName): reimplemented with Lupus
1152 2002-04-28 Miguel de Icaza <miguel@ximian.com>
1154 * statement.cs (If): correclty implement Resolve, because we were
1155 not catching sem errors in there. The same process is needed
1157 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
1160 (Statement.Warning_DeadCodeFound): Factorize code.
1161 (While): Report dead code here too.
1163 (Statement): Added Resolve virtual method to allow
1164 for resolution split from the emit code.
1166 2002-04-26 Miguel de Icaza <miguel@ximian.com>
1168 * statement.cs (EmitBoolExpression): No longer try to resolve the
1170 (MakeBoolean): New utility function that resolve, implicitly
1171 converts to boolean and tags the expression.
1174 (If, Do): Implement dead code elimination.
1175 (While): Implement loop inversion
1177 (Do, While, For, If): Resolve the expression prior to calling our
1180 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
1183 - added method Report28 (warning: program has more than one entry point)
1184 - added method IsEntryPoint, implements paragraph 10.1 of the spec
1185 - modified method Method.Define, the part at the end of the method
1187 * rootcontext.cs: added static public Location EntryPointLocation;
1189 * ../errors/cs0028.cs : Add test case for the above warning.
1192 - modified method CSharpName to allow arrays of primitive type to
1193 be printed nicely (e.g. instead of System.Int32[][] it now prints
1195 - added method CSharpSignature: returns the signature of a method
1196 in string format to be used in reporting errors, warnings, etc.
1198 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
1201 2002-04-26 Ravi Pratap <ravi@ximian.com>
1203 * delegate.cs (Define): Fix extremely silly bug where I was
1204 setting the type of the 'object' parameter of the BeginInvoke
1205 method to System.IAsyncResult instead of System.Object ;-)
1207 2002-04-26 Miguel de Icaza <miguel@ximian.com>
1209 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
1212 (Constructor.Emit): return if we fail to initialize the
1213 constructor. Another door closed!
1215 * expression.cs (New.DoResolve): Improve error message (from -6 to
1216 1501). Use DeclaredOnly lookup to find the exact constructor.
1218 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
1219 loop. This is useful.
1221 * cs-parser.jay: Adjust the default parameters so that destructors
1222 have the proper signature.
1224 2002-04-26 Martin Baulig <martin@gnome.org>
1226 * driver.cs (LoadAssembly): If `assembly' contains any characters
1227 which are only valid in path names and not in assembly names
1228 (currently slash, backslash and point), use Assembly.LoadFrom ()
1229 instead of Assembly.Load () on the `assembly' (before iteration
1230 over the link_paths).
1232 2002-04-26 Martin Baulig <martin@gnome.org>
1234 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
1236 2002-04-25 Miguel de Icaza <miguel@ximian.com>
1238 * class.cs (Property): use the new typemanager.MemberLookup
1240 (TypeContainer.MemberLookup): Implement using the
1241 TypeManager.MemberLookup now.
1243 * typemanager.cs: Make MemberLookup a function of the TypeManager,
1244 and return MemberInfos, so that these can be used without an
1245 EmitContext (what we had before).
1247 2002-04-24 Miguel de Icaza <miguel@ximian.com>
1249 * expression.cs: Fix the case where the argument to params if the
1250 type of the params. I omitted handling this before. Fixed
1252 2002-04-22 Miguel de Icaza <miguel@ximian.com>
1254 * driver.cs: Call BootCorlib_PopulateCoreType
1256 * class.cs (Property.CheckBase): Check for properties only, not
1259 * interface.cs: Temporary hack: try/catch around the
1260 CustomAttributeBuilder, because I am getting an exception that I
1263 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
1264 types whose definitions are required to be there (attributes are
1265 defined before standard types).
1267 Compute definitions as we boot the various types, as they are used
1268 immediately (value_type class will need object_type, but if we do
1269 not initialize object_type, we will pass a null, which will let
1270 the runtime pick the System.Object from the existing corlib, which
1271 is not what we want).
1273 2002-04-22 Patrik Torstensson <totte@labs2.com>
1275 * cs-tokenizer.cs: fixed a number of trim() issues.
1277 2002-04-22 Ravi Pratap <ravi@ximian.com>
1279 * expression.cs (Argument.Type): Ensure that we return the correct
1280 type when we have out or ref parameters [in which case we
1283 2002-04-22 Miguel de Icaza <miguel@ximian.com>
1285 * class.cs (Property, Indexer): Allow extern modifier in there.
1287 * typemanager.cs (InitBaseTypes): Initializes object_type and
1288 value_type, since those will be used early on during the bootstrap
1289 process to compile corlib.
1291 (InitCoreTypes): Move code from here to InitBaseTypes.
1293 2002-04-21 Miguel de Icaza <miguel@ximian.com>
1295 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
1296 single-dimension arrays as using the ldlen opcode.
1298 Daniel Lewis discovered this optimization.
1300 * typemanager.cs: Add signature for System.Array::get_Length
1302 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1304 * statement.cs: report the error when the foreach does not apply to an
1305 array nor a collection.
1307 2002-04-19 Miguel de Icaza <miguel@ximian.com>
1309 * expression.cs: Add implicit conversions to the operator ~.
1311 * constant.cs (DecimalConstant.Emit): Emit decimal value.
1313 * typemanager.cs: Locate the decimal constructor.
1315 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1317 * attribute.cs: use the new property of TypeOf.
1318 * expression.cs: added 'get' property around typearg.
1320 These changes fix a build breaker reported by NickD. Is this the
1321 correct way to fix? If not, please, revert my changes and make it
1324 2002-04-17 Miguel de Icaza <miguel@ximian.com>
1326 * attribute.cs: Add support for typeof in attribute invocations.
1327 I am not sure that this is right though.
1329 2002-04-14 Duncan Mak <duncan@ximian.com>
1331 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
1332 Binary.Operator.Division case.
1334 2002-04-13 Ravi Pratap <ravi@ximian.com>
1336 * class.cs (DefineType): Ensure that we do a proper check on
1337 attribute types and also register it with the TypeManager.
1339 (TypeContainer.Targets): The default for attribute types is
1340 AttributeTargets.All.
1342 * attribute.cs (ApplyAttributes): Registering the attribute type
1343 is done elsewhere, not when we discover we have a Usage attribute.
1345 2002-04-12 Ravi Pratap <ravi@ximian.com>
1347 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
1348 and get rid of is_delegate parameter.
1350 * everywhere : update.
1352 2002-04-12 Ravi Pratap <ravi@ximian.com>
1354 * cs-parser.jay (compilation_unit): Revamp completely to use
1355 some new ideas that I got from Rhys' grammar to solve the problems
1356 with assembly level attributes.
1358 (outer_declaration): New grammar production.
1360 (attribute_sections): Add.
1362 (opt_attributes): Base on attribute_sections
1364 (namespace_declaration): Allow opt_attributes to tackle the case
1365 when we have assembly level attributes - we are clever in this
1368 * attribute.cs (ApplyAttributes): Do not worry about assembly
1369 attributes in the non-global context.
1371 * rootcontext.cs (AddGlobalAttributes): Go back to using this
1372 instead of SetGlobalAttributes.
1374 * class.cs, rootcontext.cs : Ensure we define and generate
1375 attribute types before anything else.
1377 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
1378 and flag the new error -20 for the case when the attribute type
1379 does not have valid targets specified. csc does not catch this.
1381 * ../errors/errors.txt : update for error # -20
1383 2002-04-11 Ravi Pratap <ravi@ximian.com>
1385 * support.cs (InternalParameters.ParameterModifier): Do some null
1386 checking and return sane values.
1388 * class.cs (Method.Define): If we are a PInvoke method, ensure
1389 that we are static and extern. Report error # 601
1391 * ../errors/cs0601.cs : Add test case for the above error.
1393 2002-04-07 Ravi Pratap <ravi@ximian.com>
1395 * rootcontext.cs (attribute_types): We need to keep type of
1396 all attribute types separately and emit code for them first.
1398 (RegisterAttribute) : Implement.
1400 * class.cs (DefineType): Check if the current Type is a custom
1401 attribute type and register it accordingly.
1403 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
1404 adding the first attribute twice and rename to
1406 (SetGlobalAttributes): this.
1408 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
1411 * attribute.cs (ApplyAttributes): Take an additional argument telling us
1412 if we are processing global arguments. Hmm, I am unsure of this.
1414 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1416 * expression.cs: added static array of strings to avoid calling
1417 Enum.ToString () for Operator in Binary. Significant recover of
1420 2002-04-10 Miguel de Icaza <miguel@ximian.com>
1422 * class.cs (FindMembers): Allow the Builders of the various
1423 members to be null. If they are skip them. This only happens
1424 during the PInvoke declaration.
1426 2002-04-09 Miguel de Icaza <miguel@ximian.com>
1428 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
1429 failure, so we do not keep going afterwards.
1431 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
1432 wanted to pass `false' as the `is_delegate' argument. If this is
1433 the case, why not use delegate_type == null to mean `is_delegate =
1434 false' and anything else as is_delegate = true.
1436 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
1438 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
1439 code for the section, not the beginning of the tests.
1441 2002-04-08 Miguel de Icaza <miguel@ximian.com>
1443 * cfold.cs: Handle operator + (Enum x, Underlying x)
1445 * expression.cs (Binary): same. Warn about errors where we have
1446 Enum/Enum in operator + as well.
1448 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
1451 - added support for switch(bool)
1452 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
1453 - add TableSwitchEmit() to handle table-based switch statements
1455 2002-04-05 Ravi Pratap <ravi@ximian.com>
1457 * expression.cs (Invocation.OverloadResolve): Factor out code which
1458 does parameter compatibility checking with arguments so that we can
1459 re-use the code even from Delegate.VerifyApplicability
1461 (VerifyArgumentsCompat): Move above code here.
1463 * delegate.cs (VerifyApplicability): Get rid of duplicate code
1464 and instead make a call to the above method.
1466 2002-03-31 Ravi Pratap <ravi@ximian.com>
1468 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
1469 We use it to keep track of classes which are attribute types.
1471 2002-04-02 Miguel de Icaza <miguel@ximian.com>
1473 * delegate.cs (Delegate.Define): Correctly define the types in the
1474 presence of fixed and array parameters.
1476 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
1479 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
1480 include NonPublic after the first iteration.
1482 * class.cs (Indexer.CheckBase): Only check if both parents are
1485 * cs-parser.jay (accessor_body): If empty, set to null.
1487 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
1488 same code path here to resolve constants names that we did have in
1489 MemberAccess.DoResolve. There is too much code duplicated here.
1491 2002-04-01 Miguel de Icaza <miguel@ximian.com>
1493 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
1495 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
1498 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
1499 tokens, numbers and strings.
1501 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
1504 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
1505 asyncronous parameters and the regular parameters.
1507 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
1508 specify the target directory.
1510 * expression.cs: (This.DoResolve): Simplify
1511 (As.Emit): Optimize, do not generate IsInst if the expression is
1512 always of the given type.
1514 (Is.DoResolve): Bug fix, we were reporting both always/never for
1517 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
1518 creating too many unnecessary arrays.
1520 2002-03-31 Miguel de Icaza <miguel@ximian.com>
1522 * class.cs (EmitFieldInitializer): Use Assign expression to assign
1523 fields instead of rolling our own initializer. Takes care of all
1524 implicit conversions, and drops unnecessary static checks/argument.
1526 2002-03-31 Dick Porter <dick@ximian.com>
1528 * driver.cs: use the GetDirectories() return values properly, and
1529 use "/" as path separator.
1531 2002-03-30 Miguel de Icaza <miguel@ximian.com>
1533 * expression.cs (Unary): Optimize - - expr into expr.
1534 (Binary): Optimize a + (-b) into a -b.
1536 * codegen.cs (CodeGen): Made all methods static.
1538 2002-03-29 Miguel de Icaza <miguel@ximian.com>
1542 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
1543 TypeBuilder property.
1545 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
1548 * tree.cs: Removed the various RecordXXXX, and replaced with a
1549 single RecordDecl. Removed all the accessor methods, and just
1550 left a single access point Type
1552 * enum.cs: Rename DefineEnum to DefineType.
1554 * decl.cs: New abstract method `DefineType' used to unify the
1555 Defines for Enumerations, Interfaces, TypeContainers and
1558 (FindType): Moved LookupInterfaceOrClass here. Moved the
1559 LookupBaseClasses method that used to live in class.cs and
1560 interface.cs here, and renamed to FindType.
1562 * delegate.cs: Implement DefineType. Take advantage of the
1563 refactored pattern for locating the parent builder without taking
1564 the parent_builder argument (which we know does not work if we are
1565 nested, and triggering a toplevel definition).
1567 2002-03-28 Miguel de Icaza <miguel@ximian.com>
1569 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
1570 accessibility of a member has changed during override and report
1573 * class.cs (Method.Define, Property.Define): Only complain on
1574 overrides if the method is private, any other accessibility is
1575 fine (and since we just checked the permission is the same, we are
1578 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
1579 and elif are processed always. The other pre-processing
1580 directives are only processed if we are "taking" the path
1582 2002-03-29 Martin Baulig <martin@gnome.org>
1584 * class.cs (Method.Emit): Only emit symbolic debugging info if the
1585 current location is not Null.
1587 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
1588 a separate method so we can profile it.
1590 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
1591 `span.Seconds' are just seconds, but no minutes or hours.
1592 (MainDriver): Profile the CodeGen.SaveSymbols calls.
1594 2002-03-28 Miguel de Icaza <miguel@ximian.com>
1596 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
1597 Remove the gratuitous set of Final:
1599 // If an interface implementation, then we can set Final.
1600 if (((flags & MethodAttributes.Abstract) == 0) &&
1601 implementing.DeclaringType.IsInterface)
1602 flags |= MethodAttributes.Final;
1604 I do not know what I was smoking when I used that.
1607 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
1608 step into fixing the name resolution issues for delegates and
1609 unifying the toplevel name resolution.
1611 2002-03-28 Martin Baulig <martin@gnome.org>
1613 * class.cs (Method.Emit): If we have a symbol writer, call its
1614 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
1615 tell it about the current method.
1617 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
1618 writer that we're going to emit the first byte of IL code for a new
1619 statement (a new source line).
1620 (EmitContext.EmitTopBlock): If we have a symbol writer, call
1621 EmitContext.Mark() before emitting any code.
1623 * location.cs (SymbolDocument): Return null when we're Null.
1625 * statement.cs (Statement): Moved the `Location loc' variable here.
1626 (Statement.EmitBoolExpression): If we have a symbol writer, call
1627 ec.Mark() before emitting any code to tell it that we're at the
1628 beginning of a new statement.
1629 (StatementExpression): Added `Location' argument to the constructor.
1630 (Block): Added public readonly variable `StartLocation' and public
1631 variable `EndLocation'. The latter is to be set using SetEndLocation().
1632 (Block): Added constructor which takes a start and end location.
1633 (Block.SetEndLocation): New method. This sets the end location.
1634 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
1635 local variables we create.
1636 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
1637 each statement and do also mark the begin and end of the block.
1639 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
1640 tell it the current lexer.Location, use Location.Null for the end of the
1642 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
1643 current block, set its end location using SetEndLocation().
1644 (statement_expression): StatementExpression constructor now takes the
1645 lexer.Location as additional argument.
1646 (for_statement, declare_local_variables): Likewise.
1647 (declare_local_variables): When creating a new implicit block, use the
1648 new Block constructor and pass it the lexer.Location.
1650 2002-03-28 Miguel de Icaza <miguel@ximian.com>
1652 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
1653 members also on the parent interfaces recursively.
1655 2002-03-27 Miguel de Icaza <miguel@ximian.com>
1657 * report.cs: Use new formats, since Gonzalo finished the missing
1660 * expression.cs (Binary.ResolveOperator): added missing operator|
1661 operator& and operator^ for bool/bool.
1663 * cs-parser.jay: CheckDef now takes a Location argument that is
1664 used to report errors more precisly (instead of reporting the end
1665 of a definition, we try to track something which is a lot closer
1666 to the source of the problem).
1668 * cs-tokenizer.cs: Track global token use, so we can properly flag
1669 the use of #define/#undef after the first token has been seen.
1671 Also, rename the reportXXXX to Error_DescriptiveName
1673 * decl.cs (DeclSpace.IsTopLevel): Move property here from
1674 TypeContainer, so that Enum and Interface can use this too.
1676 * class.cs (TypeContainer.LookupInterfaceOrClass,
1677 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
1678 `builder' argument. Typically this was used to pass the parent
1679 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
1682 The problem is that a nested class could trigger the definition of
1683 a toplevel class, and the builder would be obviously wrong in that
1686 So we drop this argument, and we compute dynamically the
1687 TypeBuilder/ModuleBuilder (the correct information was available
1688 to us anyways from DeclSpace.Parent)
1690 * interface.cs (Interface.DefineInterface): Drop builder
1691 parameter cleanup like class.cs
1693 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
1696 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
1699 (Try.Emit): Propagate the returns value from the statement.
1701 (Return.Emit): Even if we are leavning
1703 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
1705 * modifiers.cs: Fix the computation of MethodAttributes flags.
1707 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
1709 * driver.cs: allow compilation of files that start with '/'.
1710 Add a default case when checking the argument of --target.
1712 2002-03-25 Miguel de Icaza <miguel@ximian.com>
1714 * interface.cs: Implement the same search algorithm for types in
1717 * delegate.cs: Do not allow multiple definition.
1719 * Recovered ChangeLog that got accidentally amputated
1721 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
1723 * rootcontext.cs: Load manually enum to allow core classes to
1724 contain enumerations.
1726 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
1727 Update to new static methods in TypeManager.
1729 * typemanager.cs (GetMethod, GetConstructor): Use our
1730 implementation of FindMembers to find the members, since during
1731 corlib compilation, the types are TypeBuilders and GetMethod and
1732 GetConstructor do not work.
1734 Make all methods in TypeManager static.
1736 (InitCodeHelpers): Split the functionality from
1737 the InitCodeTypes function.
1739 * driver.cs: Call InitCodeHelpers after we have populated the
1742 * cs-parser.jay (delegate_declaration): we did not used to compute
1743 the delegate name correctly for void delegates.
1745 2002-03-24 Miguel de Icaza <miguel@ximian.com>
1747 * rootcontext.cs (RootContext): Init the interface_resolve_order
1748 and type_container_resolve_order always.
1750 (ResolveCore, BootstrapCorlib_ResolveClass,
1751 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
1752 compiler when compiling with --nostdlib
1754 * class.cs (TypeContainer.DefineType): Check that our parent is
1755 not null. This test is most important when we are bootstraping
1758 * codegen.cs: Split out the symbol writing code.
1760 2002-03-25 Martin Baulig <martin@gnome.org>
1762 * driver.cs (-g): Made -g an alias for --debug.
1764 2002-03-24 Martin Baulig <martin@gnome.org>
1766 * codegen.cs (SymbolWriter): New public variable. Returns the
1767 current symbol writer.
1768 (CodeGen): Added `bool want_debugging_support' argument to the
1769 constructor. If true, tell the ModuleBuild that we want debugging
1770 support and ask it for the ISymbolWriter.
1771 (Save): If we have a symbol writer, call it's Close() method after
1772 saving the assembly.
1774 * driver.c (--debug): New command line argument to create a
1775 debugger information file.
1777 * location.cs (SymbolDocument): New public property. Returns an
1778 ISymbolDocumentWriter object for the current source file or null
1779 if we don't have a symbol writer.
1781 2002-03-21 Miguel de Icaza <miguel@ximian.com>
1783 * driver.cs (LoadAssembly): Correctly return when all the paths
1784 have been tried and not before.
1786 * statement.cs (Switch.Emit): return the actual coverage for this
1787 statement (returns/not-returns)
1789 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
1790 switch of the statement if we are the last switch section. That
1791 kills two problems: try/catch problems (we used to emit an empty
1792 nop at the end) and switch statements where all branches would
1795 2002-03-19 Miguel de Icaza <miguel@ximian.com>
1797 * driver.cs: Add default assemblies (the equivalent to the
1798 Microsoft CSC.RSP file)
1800 * cs-tokenizer.cs: When updating `cols and setting it to zero,
1801 also update tokens_seen and set it to false.
1803 * driver.cs: Implement --recurse for Mike.
1805 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
1806 correctly splitting out the paths.
1808 2002-03-18 Miguel de Icaza <miguel@ximian.com>
1810 * interface.cs (Interface.PopulateProperty): Instead of using
1811 `parent' as the declaration space for the set parameters, use
1814 * support.cs (InternalParameters): InternalParameters constructor
1815 takes a DeclSpace instead of a TypeContainer.
1817 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
1818 types are being initialized, load the address of it before calling
1821 (New): Provide a mechanism to disable the generation of local
1822 value type temporaries when the caller will be providing us with
1823 an address to store it.
1825 (ArrayCreation.EmitDynamicInitializers): Use it.
1827 2002-03-17 Miguel de Icaza <miguel@ximian.com>
1829 * expression.cs (Invocation.EmitArguments): Only probe for array
1830 property if there is more than one argument. Sorry about that.
1832 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
1835 * class.cs (Method.LabelParameters): Fix incorrect code path that
1836 prevented the `ParamArrayAttribute' from being applied to the
1839 2002-03-16 Miguel de Icaza <miguel@ximian.com>
1841 * support.cs (ReflectionParameters): Correctly compute whether the
1842 last argument is a params array. Fixes the problem with
1845 * typemanager.cs: Make the assemblies array always be non-null
1846 (empty, but non-null)
1848 * tree.cs (RecordDecl): New function that abstracts the recording
1849 of names. This reports error 101, and provides a pointer to the
1850 previous declaration. Fixes a crash in the compiler.
1852 * cs-parser.jay (constructor_declaration): Update to new grammar,
1853 and provide a constructor_body that can be empty.
1855 2002-03-15 Miguel de Icaza <miguel@ximian.com>
1857 * driver.cs: Add support for --resources.
1859 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
1860 Make all types for the various array helper methods be integer.
1862 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
1863 CheckState to ConvCast.
1865 (ConvCast): Now it takes a `checked' state argument, to avoid
1866 depending on the emit context for the conversion, and just using
1867 the resolve time setting.
1869 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
1870 instead of Invocation.EmitArguments. We do not emit the original
1871 arguments, instead we emit those which have been converted to
1872 unsigned int expressions.
1874 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
1876 * codegen.cs: ditto.
1878 * expression.cs (LocalVariableReference): Drop the use of the
1879 Store function that depended on the variable index.
1881 * statement.cs (VariableInfo): Drop the `Idx' property from this
1882 class, as this is not taking into account the indexes for
1883 temporaries tat we generate during the execution, getting the
1886 * class.cs: First emit class initializers, then call the parent
1889 * expression.cs (Binary): Fix opcode emision.
1890 (UnaryMutator.EmitCode): Support checked code generation
1892 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
1893 matches for events for both the Static and Instance scans,
1894 pointing to the same element. Fix that.
1896 2002-03-14 Miguel de Icaza <miguel@ximian.com>
1898 * rootcontext.cs (ResolveTree): Always set the
1899 interface_resolve_order, because nested interfaces will be calling
1902 * class.cs (GetInterfaceOrClass): Track the same resolution
1903 process used by TypeManager.LookupType. This fixes the nested
1904 type lookups in class declarations (separate path from
1907 (TypeContainer.DefineType): Also define nested interfaces.
1908 (TypeContainer.RegisterOrder): New public function used to
1909 register the order in which child interfaces need to be closed.
1911 Nested interfaces need to be closed after their parents have been
1914 * interface.cs (InterfaceAttr): Put all the logic for computing
1915 the interface attribute here.
1917 (DefineInterface): Register our interface order with the
1918 RootContext or with the TypeContainer depending on the case.
1920 2002-03-12 Miguel de Icaza <miguel@ximian.com>
1922 * cs-parser.jay: rework foreach statement to work with the new
1923 changes to the policy on SimpleNames.
1925 * report.cs: support Stacktrace on warnings as well.
1927 * makefile: drop --unsafe and /unsafe from the compile.
1929 2002-03-13 Ravi Pratap <ravi@ximian.com>
1931 * ecore.cs (StandardConversionExists): Modify to take an Expression
1932 as the first parameter. Ensure we do null -> reference type conversion
1935 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
1936 temporary Expression objects.
1938 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
1940 * interface.cs: workaround bug in method overloading resolution
1941 (there is already a bugzilla bug for it).
1943 2002-03-12 Miguel de Icaza <miguel@ximian.com>
1945 We could also solve this problem by having a separate path for
1946 performing type lookups, instead of DoResolve, we could have a
1947 ResolveType entry point, and only participating pieces of the
1948 production (simplename, deref, array) would implement this.
1950 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
1951 signal SimpleName to only resolve type names and not attempt to
1952 resolve anything else.
1954 * expression.cs (Cast): Set the flag.
1956 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
1958 * class.cs: Only report 108 if there is no `new' modifier.
1960 * cs-parser.jay: rework foreach statement to work with the new
1961 changes to the policy on SimpleNames.
1963 * report.cs: support Stacktrace on warnings as well.
1965 * makefile: drop --unsafe and /unsafe from the compile.
1967 2002-03-11 Miguel de Icaza <miguel@ximian.com>
1969 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
1970 lookups here, instead of doing that at parse time. This means
1971 that our grammar will not introduce `LocalVariableReferences' as
1972 expressions at this point. That solves the problem of code like
1980 This is only half the fix. The full fix requires parameters to
1981 also be handled in this way.
1983 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
1984 makes the use more obvious of the DeclSpace. The
1985 ec.TypeContainer.TypeBuilder is now only used to pull the
1988 My theory is that I can get rid of the TypeBuilder completely from
1989 the EmitContext, and have typecasts where it is used (from
1990 DeclSpace to where it matters).
1992 The only pending problem is that the code that implements Aliases
1993 is on TypeContainer, and probably should go in DeclSpace.
1995 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
1996 lookups here, instead of doing that at parse time. This means
1997 that our grammar will not introduce `LocalVariableReferences' as
1998 expressions at this point. That solves the problem of code like
2006 This is only half the fix. The full fix requires parameters to
2007 also be handled in this way.
2009 * class.cs (Property.DefineMethod): When implementing an interface
2010 method, set newslot, when implementing an abstract method, do not
2011 set the flag (before we tried never setting it, or always setting
2012 it, which is the difference).
2013 (Indexer.DefineMethod): same.
2014 (Method.DefineMethod): same.
2016 * ecore.cs: Only set the status used flag if we get back a Field.
2018 * attribute.cs: Temporary hack, so Paolo can keep working.
2020 2002-03-08 Ravi Pratap <ravi@ximian.com>
2022 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
2023 the unmanaged type in the case we have a MarshalAs attribute.
2025 (Resolve): Handle the case when we are parsing the special MarshalAs
2026 attribute [we need to store the unmanaged type to use later]
2028 * typemanager.cs (marshal_as_attr_type): Built in type for the
2029 MarshalAs Attribute.
2031 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
2032 on parameters and accordingly set the marshalling info.
2034 2002-03-09 Miguel de Icaza <miguel@ximian.com>
2036 * class.cs: Optimizing slightly by removing redundant code after
2037 we switched to the `NoTypes' return value.
2038 (Property.DefineMethod): use NoTypes here too.
2040 This fixes the bug I introduced in my last batch of changes.
2042 2002-03-05 Ravi Pratap <ravi@ximian.com>
2044 * tree.cs (RecordEnum): Add. We now keep track of enums too.
2046 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
2047 Enums since those are types too.
2049 * cs-parser.jay (enum_declaration): Record enums as we parse them.
2051 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
2052 thanks to a call during the lookup process.
2054 2002-03-07 Miguel de Icaza <miguel@ximian.com>
2056 * statement.cs (Foreach): Lots of work to accomodate a particular
2057 kind of foreach statement that I had not kept in mind. It is
2058 possible to have foreachs on classes that provide a GetEnumerator
2059 method that return objects that implement the "pattern" for using
2060 a foreach, there is no need to support GetEnumerator
2063 This is needed to compile nant.
2065 * decl.cs: Only report 114 if the member is not `Finalize' and if
2066 the warning level is at least 2.
2068 * class.cs: Moved the compare function from Method to
2071 (MethodSignature.InheritableMemberSignatureCompare): Add new
2072 filter function that is used to extract inheritable methods from a
2075 (Method.Define): Use the new `inheritable_method_signature_filter'
2078 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
2081 2002-03-06 Miguel de Icaza <miguel@ximian.com>
2083 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
2085 * cs-parser.jay: Add opt_semicolon to the interface declaration.
2087 * expression.cs: Pass location information to
2088 ConvertImplicitStandard.
2090 * class.cs: Added debugging code to track return values from
2093 2002-03-05 Miguel de Icaza <miguel@ximian.com>
2095 * expression.cs (Is.DoResolve): If either side of the `is' is an
2096 interface, do not flag the warning.
2098 * ecore.cs (ImplicitReferenceConversion): We need a separate test
2101 * report.cs: Allow for --fatal to be used with --probe.
2103 * typemanager.cs (NoTypes): Move the definition for the empty Type
2106 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
2108 (TypeContainer.DefineProxy): New function used to proxy to parent
2109 implementations when implementing interfaces.
2110 (TypeContainer.ParentImplements): used to lookup if our parent
2111 implements a public function that is required by an interface.
2112 (TypeContainer.VerifyPendingMethods): Hook this up.
2114 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
2115 `modules' and `assemblies' arraylists into arrays. We only grow
2116 these are the very early start up of the program, so this improves
2117 the speedof LookupType (nicely measured).
2119 * expression.cs (MakeByteBlob): Replaced unsafe code with
2120 BitConverter, as suggested by Paolo.
2122 * cfold.cs (ConstantFold.Binary): Special case: perform constant
2123 folding of string concatenation, but if either side is a string,
2124 and the other is not, then return null, and let the runtime use
2125 the concatenation on the string plus the object (using
2128 2002-03-04 Miguel de Icaza <miguel@ximian.com>
2130 Constant Folding has been implemented now.
2132 * expression.cs (Unary.Reduce): Do not throw an exception, catch
2133 the error instead on types that are not supported in one's
2136 * constant.cs (Constant and all children): New set of functions to
2137 perform implict and explicit conversions.
2139 * ecore.cs (EnumConstant): Implement the new functions to perform
2140 conversion by proxying to the child expression.
2142 * codegen.cs: (ConstantCheckState): Constant evaluation has its
2143 own separate setting that can not be turned off from the command
2144 line using --unchecked or --checked and is only controlled using
2145 the checked/unchecked statements and expressions. This setting is
2146 used by the constant folder to flag errors.
2148 * expression.cs (CheckedExpr, UncheckedExpr): Set the
2149 ConstantCheckState as well.
2151 During Resolve, they also have to flag the state, because the
2152 constant folder runs completely in the Resolve phase.
2154 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
2157 2002-03-01 Miguel de Icaza <miguel@ximian.com>
2159 * cfold.cs: New file, this file contains the constant folder.
2161 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
2162 argument to track whether we are using the resulting address to
2163 load or store a value and provide better error messages.
2165 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
2166 new AddressOf arguments.
2168 * statement.cs (Foreach.EmitCollectionForeach): Update
2170 * expression.cs (Argument.Emit): Call AddressOf with proper
2171 arguments to track usage.
2173 (New.DoEmit): Call AddressOf with new arguments.
2175 (Unary.Emit): Adjust AddressOf call.
2177 2002-03-01 Ravi Pratap <ravi@ximian.com>
2179 * cs-parser.jay (member_access): Change the case for pre-defined types
2180 to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
2183 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
2186 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
2187 essentially like methods and apply attributes like MethodImplOptions to them too.
2189 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
2192 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
2193 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
2196 * Update code everywhere accordingly.
2198 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
2200 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
2202 2002-02-28 Ravi Pratap <ravi@ximian.com>
2204 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
2205 try performing lookups against those instead of jumping straight into using
2206 the 'using' clauses.
2208 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
2210 (LookupType): Perform lookups in implicit parents too.
2212 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
2213 sequence as RootContext.LookupType.
2215 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
2216 the various cases of namespace lookups into this method.
2218 2002-03-01 Miguel de Icaza <miguel@ximian.com>
2220 * cs-parser.jay: Add support for [Attribute ()] (empty arguments
2221 in positional arguments)
2223 * class.cs (Operator): Update the AllowedModifiers to contain
2226 * cs-parser.jay: Update operator declaration to allow for the
2227 operator body to be empty.
2229 * cs-tokenizer.cs: Added '\u' unicode support in strings and hex
2232 2002-02-27 Miguel de Icaza <miguel@ximian.com>
2234 * class.cs (Method.Emit): Label parameters.
2236 * driver.cs: Return 1 or 0 as the program exit code.
2238 2002-02-26 Miguel de Icaza <miguel@ximian.com>
2240 * expression.cs: Special case the `null' object when trying to
2241 auto-compute the type, as anything can be explicitly converted to
2244 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
2245 spotting this Paolo.
2247 (Expression.ImplicitNumericConversion): Perform comparissions of
2248 the type using the underlying type in the case of an enumeration
2249 rather than using the enumeration type for the compare.
2251 Cope with the underlying == type case, which is not possible to
2254 (Expression.ConvertNumericExplicit): Perform comparissions of
2255 the type using the underlying type in the case of an enumeration
2256 rather than using the enumeration type for the compare.
2258 * driver.cs: If the user does not supply an extension, assume .exe
2260 * cs-parser.jay (if_statement): Rewrote so that we can track the
2261 location for the if statement.
2263 * expression.cs (Binary.ConstantFold): Only concat strings when
2264 the operation is "+", not everything ;-)
2266 * statement.cs (Statement.EmitBoolExpression): Take a location
2268 (If, While, Do): Track location.
2270 * expression.cs (Binary.ResolveOperator): In the object + string
2271 case, I was missing a call to ConvertImplicit
2273 2002-02-25 Ravi Pratap <ravi@ximian.com>
2275 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
2276 Location arguments. Ensure we use RootContext.LookupType to do our work
2277 and not try to do a direct Type.GetType and ModuleBuilder.GetType
2279 * interface.cs (PopulateMethod): Handle the type of the parameter being
2282 * expression.cs (Invocation.BetterFunction): Handle the case when we
2283 have a params method with no fixed arguments and a call is made with no
2286 2002-02-25 Miguel de Icaza <miguel@ximian.com>
2288 * cs-tokenizer.cs: Add support for the quote-escape-sequence in
2289 the verbatim-string-literal
2291 * support.cs (InternalParameters.ParameterModifier): handle null
2293 (InternalParameters.ParameterType): ditto.
2295 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
2296 duplicating the name of the variable parameter.
2297 (GetParameterByName): Fix bug where we were not looking up array
2298 paramters if they were the only present (thanks Paolo!).
2299 (GetParameterInfo): We only have an empty set of types if both
2300 fixed and array are set to null.
2301 (GetParameterInfo-idx): Handle FixedParameter == null
2303 * cs-parser.jay: Handle the case where there is no catch
2304 statements (missing null test).
2306 2002-02-22 Miguel de Icaza <miguel@ximian.com>
2308 * driver.cs (MainDriver): Be conservative on our command line
2311 Catch DirectoryNotFoundException when calling GetFiles.
2313 (SplitPathAndPattern): Used to split the input specification into
2314 a path and a pattern that we can feed to Directory.GetFiles.
2316 2002-02-21 Miguel de Icaza <miguel@ximian.com>
2318 * statement.cs (Fixed): Implement the last case of the Fixed
2319 statement (string handling).
2321 * expression.cs (StringPtr): New class used to return a char * to
2322 a string; Used by the Fixed statement.
2324 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
2326 * expression.cs (Binary.ResolveOperator): Remove redundant
2327 MemberLookup pn parent type.
2328 Optimize union call, we do not need a union if the types are the same.
2329 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
2332 Specialize the use of MemberLookup everywhere, instead of using
2333 the default settings.
2335 (StackAlloc): Implement stackalloc keyword.
2337 * cs-parser.jay: Add rule to parse stackalloc.
2339 * driver.cs: Handle /h, /help, /?
2341 * expression.cs (MakeByteBlob): Removed the hacks we had in place
2342 before we supported unsafe code.
2344 * makefile: add --unsafe to the self compilation of mcs.
2346 2002-02-20 Miguel de Icaza <miguel@ximian.com>
2348 * expression.cs (PointerArithmetic): New class that is used to
2349 perform pointer arithmetic.
2350 (Binary.Resolve): Handle pointer arithmetic
2351 Handle pointer comparission.
2352 (ArrayPtr): Utility expression class that is used to take the
2353 address of an array.
2355 (ElementAccess): Implement array access for pointers
2357 * statement.cs (Fixed): Implement fixed statement for arrays, we
2358 are missing one more case before we are done.
2360 * expression.cs (Indirection): Implement EmitAssign and set the
2361 ExprClass to Variable. This allows pointer dereferences to be
2362 treated as variables, and to have values assigned to them.
2364 * ecore.cs (Expression.StoreFromPtr): New utility function to
2365 store values dereferencing.
2367 2002-02-20 Ravi Pratap <ravi@ximian.com>
2369 * expression.cs (Binary.ResolveOperator): Ensure that we are
2370 not trying to operate on a void type - this fixes the reported
2373 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
2374 the parent implementation is sealed.
2376 * ../errors/cs0239.cs : Add.
2378 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
2380 * typemanager.cs (unverifiable_code_type): Corresponds to
2381 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
2382 which have unsafe code in them.
2384 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
2387 2002-02-19 Miguel de Icaza <miguel@ximian.com>
2389 * cs-tokenizer.cs: Add support for @"litreal strings"
2391 Make tokenizer accept pre-processor directives
2392 on any column (remove the old C-like limitation).
2394 * rootcontext.cs (EmitCode): Emit any global attributes.
2395 (AddGlobalAttributes): Used to keep track of assembly attributes.
2397 * attribute.cs (ApplyAttributes): Support AssemblyAttributes.
2399 * cs-parser.jay: Add support for global attributes.
2401 2002-02-17 Miguel de Icaza <miguel@ximian.com>
2403 * expression.cs (Indirection): New helper class. Unary will
2404 create Indirection classes to be able to implement the
2405 IMemoryLocation interface on it.
2407 2002-02-16 Miguel de Icaza <miguel@ximian.com>
2409 * cs-parser.jay (fixed_statement): reference the right statement.
2411 * statement.cs (Fixed.Emit): Finish implementing the fixed
2412 statement for the &x case.
2414 2002-02-14 Miguel de Icaza <miguel@ximian.com>
2416 * class.cs (Property.Define, Method.Define): Remove newslot when
2419 * modifiers.cs: My use of NewSlot when `Abstract' was set was
2420 wrong. NewSlot should only be used if the `new' keyword is present.
2422 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
2423 locating our system dir. Sorry about this.
2425 2002-02-13 Miguel de Icaza <miguel@ximian.com>
2427 * driver.cs (GetSystemDir): Compute correctly the location of our
2428 system assemblies. I was using the compiler directory instead of
2429 the library directory.
2431 2002-02-13 Ravi Pratap <ravi@ximian.com>
2433 * expression.cs (BetterFunction): Put back in what Miguel commented out
2434 since it is the correct fix. The problem is elsewhere ;-)
2436 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
2437 parameters of the parms method are themselves compatible or not !
2439 (StandardConversionExists): Fix very dangerous bug where we were forgetting
2440 to check that a class implements an interface before saying that an implicit
2441 conversion was allowed. Use ImplementsInterface to do the checking.
2443 2002-02-13 Miguel de Icaza <miguel@ximian.com>
2445 * class.cs (Method.Define): Track whether we are an explicit
2446 implementation or not. And only call DefineMethodOverride if we
2447 are an explicit implementation.
2449 (Property.DefineMethod): Ditto.
2451 2002-02-11 Ravi Pratap <ravi@ximian.com>
2453 * expression.cs (BetterFunction): Catch hideous bug which was
2454 preventing us from detecting ambiguous calls due to implicit casts i.e
2457 2002-01-29 Miguel de Icaza <miguel@ximian.com>
2459 * support.cs (Pair): Remove un-needed method. I figured why I was
2460 getting the error in cs-parser.jay, the variable in a foreach loop
2461 is readonly, and the compiler does not really treat this as a variable.
2463 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
2464 instead of EQUALS in grammar.
2466 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
2468 * expression.cs (Unary.DoResolve): Check whether the argument is
2471 2002-01-28 Miguel de Icaza <miguel@ximian.com>
2473 * support.cs: Api for Pair to set a value. Despite the fact that
2474 the variables are public the MS C# compiler refuses to compile
2475 code that accesses the field if the variable is part of a foreach
2478 * statement.cs (Fixed): Begin implementation of the fixed
2481 (Block.AddVariable): Return the VariableInfo on success and null
2482 on failure instead of true/false.
2484 * cs-parser.jay (foreach): Catch errors on variables already
2485 defined (we were ignoring this value before) and properly unwind
2488 (fixed_statement): grammar for the fixed statement.
2490 2002-01-25 Miguel de Icaza <miguel@ximian.com>
2492 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
2493 pointer types to be incretemented.
2495 (SizeOf): Implement.
2497 * cs-parser.jay (pointer_member_access): Implement
2498 expr->IDENTIFIER production.
2500 * expression.cs (IndexerAccess.DoResolve, ArrayAccess.DoResolve,
2501 MemberAccess.DoResolve, Invocation.DoResolve): Check for pointers
2504 (Unary): Implement indirection.
2506 * ecore.cs (Expression.UnsafeError): Reports error 214 (pointer
2507 use in non-unsafe context).
2509 (SimpleName.DoResolve): Check for pointers in field access on safe
2512 (Expression.LoadFromPtr): Factor the load-indirect code in this
2513 function. This was duplicated in UnboxCast and ParameterReference
2515 2002-01-24 Miguel de Icaza <miguel@ximian.com>
2517 * expression.cs (ComposedCast): report an error if a pointer cast
2518 is used in a safe region.
2520 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
2521 pointer type casts in unsafe context.
2523 * codegen.cs (EmitContext): Set up IsUnsafe.
2525 * cs-parser.jay (non_expression_type): Add productions for pointer
2528 * expression.cs (Invocation.EmitCall): Remove chunk of buggy
2529 code. We should not use force into static mode if the method is
2530 not virtual. Fixes bug in MIS
2532 * statement.cs (Do.Emit, While.Emit, For.Emit,
2533 Statement.EmitBoolExpression): Add support to Do and While to
2534 propagate infinite loop as `I do return' semantics.
2536 Improve the For case to also test for boolean constants.
2538 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
2539 to the list of attributes we can add.
2541 Remove `EmitContext' argument.
2543 * class.cs (Method.Define): Apply parameter attributes.
2544 (Constructor.Define): Apply parameter attributes.
2545 (MethodCore.LabelParameters): Move here the core of labeling
2548 * support.cs (ReflectionParameters.ParameterModifier,
2549 InternalParameters.ParameterModifier): Use IsByRef on the type and
2550 only return the OUT bit for these parameters instead of in/out/ref
2553 This is because I miss-understood things. The ParameterInfo.IsIn
2554 and IsOut represent whether the parameter has the [In] and [Out]
2557 2002-01-22 Miguel de Icaza <miguel@ximian.com>
2559 * ecore.cs (FieldExpr.Emit): Release temporaries.
2561 * assign.cs (LocalTemporary.Release): new function.
2563 * codegen.cs (EmitContext.GetTemporaryStorage,
2564 EmitContext.FreeTemporaryStorage): Rework the way we deal with
2565 temporary storage. Now we can "put back" localbuilders when we
2568 2002-01-21 Miguel de Icaza <miguel@ximian.com>
2570 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
2571 need to make a copy of the variable to generate verifiable code.
2573 2002-01-19 Miguel de Icaza <miguel@ximian.com>
2575 * driver.cs: Compute dynamically the system directory.
2577 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
2578 Slower, but more generally useful. Used by the abstract
2579 registering implementation.
2581 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
2582 the rules for the special rule on Type/instances. First check if
2583 we have the same name, and if so, try that special static path
2584 rather than the instance path.
2586 2002-01-18 Miguel de Icaza <miguel@ximian.com>
2588 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
2591 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
2592 Enum, ValueType, Delegate or Array for non-corlib compiles.
2594 * cs-tokenizer.cs: Catch long identifiers (645)
2596 * typemanager.cs (IndexerPropetyName): Ravi never tested this
2599 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
2600 fix, we were returning too early, so we were not registering
2601 pending methods from abstract classes.
2603 Do not register pending methods if the class is abstract.
2605 * expression.cs (Conditional.DoResolve): Report circular implicit
2606 conversions when we neecd to compute it for conditional
2609 (Is.DoResolve): If the expression is always of the provided type,
2610 flag warning 183. If the expression can not ever be of the
2611 provided type flag warning 184.
2613 * class.cs: Catch 169 as well.
2615 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
2618 2002-01-18 Nick Drochak <ndrochak@gol.com>
2620 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.
2622 2002-01-17 Miguel de Icaza <miguel@ximian.com>
2624 * interface.cs: (PopulateMethod): Check for pointers being defined
2625 only if the unsafe context is active.
2626 (PopulateProperty): ditto.
2627 (PopulateIndexer): ditto.
2629 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
2630 specified. If pointers are present, make sure that they are
2631 present in an unsafe context.
2632 (Constructor, Constructor.Define): ditto.
2633 (Field, Field.Define): ditto.
2634 (Property, Property.Define): ditto.
2635 (Event, Event.Define): ditto.
2637 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
2638 hashtable if there are classes or structs defined.
2640 * expression.cs (LocalVariableReference.DoResolve): Simplify this
2641 code, as the constant resolution moved.
2643 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
2644 the metadata, so we can flag error 133.
2646 * decl.cs (MemberCore.UnsafeOK): New function to test that a
2647 pointer is being declared in an unsafe context.
2649 2002-01-16 Miguel de Icaza <miguel@ximian.com>
2651 * modifiers.cs (Modifiers.Check): Require a Location argument.
2652 Report error 227 for Unsafe use.
2654 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
2656 * statement.cs (For.Emit): If the test is null, then report that
2657 we do `return', as we wont reach anything afterwards.
2659 (Switch.SwitchGoverningType): Track the expression that matched
2662 * driver.cs: Allow negative numbers as an error code to flag.
2664 * cs-parser.jay: Handle 1551.
2666 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
2668 2002-01-15 Miguel de Icaza <miguel@ximian.com>
2670 * cs-parser.jay: Report 1518 (type declaration can only contain
2671 class, struct, interface, enum or delegate)
2673 (switch_label): Report 1523 (keywords `case' or `default' must
2676 (opt_switch_sections): Report 1522 (empty switch)
2678 * driver.cs: Report 1515 (response file specified multiple times)
2679 Report 1516 (Source file specified multiple times).
2681 * expression.cs (Argument.Resolve): Signal 1510
2683 (BaseAccess.Resolve, BaseIndexer.Resolve): Signal 1511 (base
2684 access not allowed in static code)
2686 2002-01-11 Ravi Pratap <ravi@ximian.com>
2688 * typemanager.cs (IsPointerType): Utility method which we are going
2691 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
2692 the object type, so we take care of that.
2694 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
2696 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
2697 added to non-params parameters :-)
2699 * typemanager.cs (CSharpName): Include 'void' type too.
2701 (void_ptr_type): Include in the set of core types.
2703 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
2706 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
2709 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
2710 completely forgotten about it.
2712 2002-01-10 Ravi Pratap <ravi@ximian.com>
2714 * cs-parser.jay (pointer_type): Add. This begins our implementation
2715 of parsing rules for unsafe code.
2717 (unsafe_statement): Implement.
2719 (embedded_statement): Modify to include the above.
2721 * statement.cs (Unsafe): Implement new class for unsafe blocks.
2723 * codegen.cs (EmitContext.InUnsafe): Add. This determines
2724 if the current context is an unsafe one.
2726 * cs-parser.jay (local_variable_pointer_type): Since local variable types
2727 are handled differently, we need separate rules for them.
2729 (local_variable_declaration): Update to use local_variable_pointer_type
2730 to allow variable declarations of unmanaged pointer types.
2732 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
2735 * ../errors/cs0214.cs : Add.
2737 2002-01-16 Nick Drochak <ndrochak@gol.com>
2739 * makefile: remove 'response' file when cleaning.
2741 2002-01-15 Miguel de Icaza <miguel@ximian.com>
2743 * cs-parser.jay: Report 1524.
2745 2002-01-14 Miguel de Icaza <miguel@ximian.com>
2747 * typemanager.cs (RegisterMethod): drop checking if we have
2748 registered this from here
2750 2002-01-12 Miguel de Icaza <miguel@ximian.com>
2752 * class.cs (Method.EmitDestructor): Implement calling our base
2755 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
2758 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
2759 this routine and will wrap the call in a try/catch block. Deal
2762 2002-01-11 Miguel de Icaza <miguel@ximian.com>
2764 * ecore.cs (Expression.MemberLookup): instead of taking a
2765 parameter `same_type' that was used to tell whether we could
2766 access private members we compute our containing type from the
2769 (FieldExpr): Added partial support for volatile fields. This does
2770 not work for volatile fields exposed from assemblies, as I can not
2771 figure out how to extract the modreq from it.
2773 Updated all the source files to use this.
2775 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
2776 because it is referenced by MemberLookup very often.
2778 2002-01-09 Ravi Pratap <ravi@ximian.com>
2780 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
2781 TypeBuilder.GetCustomAttributes to retrieve what we need.
2783 Get rid of redundant default_member_attr_type as this is the same as
2784 default_member_type which already exists.
2786 * interface.cs, attribute.cs : Update accordingly.
2788 2002-01-08 Miguel de Icaza <miguel@ximian.com>
2790 * typemanager.cs: Enable IndexerPropertyName again. It does not
2791 work for TYpeBuilders though. Ravi, can you please fix this?
2793 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
2795 * expression.cs (Argument.Emit): Handle the case of ref objects
2796 being passed to ref functions;
2798 (ParameterReference.EmitLoad): Loads the content of the pointer
2799 without dereferencing.
2801 2002-01-07 Miguel de Icaza <miguel@ximian.com>
2803 * cs-tokenizer.cs: Implemented the pre-processing expressions.
2805 2002-01-08 Ravi Pratap <ravi@ximian.com>
2807 * class.cs (Indexer.DefineMethod): Incorporate the interface
2808 type in the name of the method if we are doing explicit interface
2811 * expression.cs (ConversionExists): Remove as it is completely obsolete.
2813 (BetterConversion): Fix extremely trivial bug where we were referring to
2814 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
2817 * ../errors/bug16.cs : Add although we have fixed it.
2819 2002-01-07 Miguel de Icaza <miguel@ximian.com>
2821 * expression.cs (BaseIndexer): Begin implementation.
2823 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
2825 * cs-parser.jay (indexer_declarator): Use qualified_identifier
2826 production directly to remove a shift/reduce, and implement
2827 explicit interface implementation.
2829 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
2830 after a floating point suffix.
2832 * expression.cs (DoNumericPromotions): Improved the conversion for
2833 uint/uint. If we have a constant, we avoid doing a typecast to a
2836 * class.cs (Indexer): Implement explicit interface implementation
2839 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
2841 * class.cs: make the default instance constructor public and hidebysig.
2843 2001-01-03 Ravi Pratap <ravi@ximian.com>
2845 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
2846 so we can call it from elsewhere.
2848 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
2849 we emit it internally if the class has a defined indexer; otherwise the user
2850 emits it by decorating the class definition with the DefaultMemberAttribute.
2852 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
2853 attribute is not used on a type which defines an indexer.
2855 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
2856 character when we skip whitespace.
2858 * ../errors/cs0646.cs : Add.
2860 2002-01-03 Miguel de Icaza <miguel@ximian.com>
2862 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
2865 * makefile: Add practical target `mcs3.exe' which builds the third
2866 generation compiler.
2868 * expression.cs (New): Fix structures constructor calling.
2870 * class.cs (Property, Method, Indexer): Emit Final flag on the
2871 method if we are an interface implementation and we are not
2874 * ecore.cs (PropertyExpr): New public field `IsBase', tells
2875 whether this property is referencing a `base' method.
2877 * expression.cs (Invocation.EmitCall): take an extra argument:
2878 is_base, this is used to determine whether the `call' or
2879 `callvirt' opcode should be used.
2882 * delegate.cs: update EmitCall.
2884 * class.cs (Method.Define): Set NewSlot for the cases where we are
2885 not implementing an interface method.
2887 (Property.Define): ditto.
2889 2002-01-02 Miguel de Icaza <miguel@ximian.com>
2891 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
2892 'r'. Allows mcs to parse itself fully.
2894 2002-01-02 Ravi Pratap <ravi@ximian.com>
2896 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
2897 of the number of initializers that require the InitializeArray method.
2899 (CheckIndices): Store the Expression in all cases - not the plain value. Also
2900 update the above field where necessary.
2902 (MakeByteBlob): Update accordingly.
2904 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
2907 (EmitDynamicInitializers): Update in accordance with the new optimization.
2909 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
2910 same OpCode applies.
2912 * cs-parser.jay : Fix some glaring errors I introduced.
2914 2002-01-01 Ravi Pratap <ravi@ximian.com>
2916 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
2917 so that we can check for name clashes there too.
2919 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
2920 for interface indexers.
2922 * interfaces.cs (Define): Emit the default member attribute.
2924 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
2925 variable was being referred to while setting the value ;-)
2927 2002-01-01 Miguel de Icaza <miguel@ximian.com>
2929 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
2930 byte-by-byte information when we know the data is zero.
2932 Make the block always a multiple of 4, because
2933 DefineInitializedData has a bug.
2935 * assign.cs: Fix, we should assign from the temporary, not from
2938 * expression.cs (MakeByteBlob): Fix my incorrect code.
2940 2001-12-31 Miguel de Icaza <miguel@ximian.com>
2942 * typemanager.cs (EnumToUnderlying): This function is used to get
2943 the underlying type from an enumeration, because it does not
2946 * constant.cs: Use the I4_S form for values between -128 and 127.
2948 * statement.cs (Block.LookupLabel): Looks up a label.
2949 (Block): Drop support for labeled blocks.
2951 (LabeledStatement): New kind of statement that represents a label
2954 (Goto): Finally implement this bad boy.
2956 * cs-parser.jay: Update to reflect new mechanism to implement
2959 2001-12-30 Miguel de Icaza <miguel@ximian.com>
2961 * codegen.cs (EmitContext.This): a codegen property that keeps the
2962 a single instance of this instead of creating many different this
2965 * delegate.cs (Delegate.DoResolve): Update to use the property;
2967 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
2969 * expression.cs (BaseAccess.DoResolve): Ditto.
2971 2001-12-29 Ravi Pratap <ravi@ximian.com>
2973 * typemanager.cs (methodimpl_attr_type): Add to hold the type
2974 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
2976 (InitCoreTypes): Update accordingly.
2978 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
2979 so we can quickly store the state.
2981 (ApplyAttributes): Set the correct implementation flags
2982 for InternalCall methods.
2984 2001-12-29 Miguel de Icaza <miguel@ximian.com>
2986 * expression.cs (EmitCall): if a method is not virtual, then do
2987 not use callvirt on it.
2989 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
2990 user defined stuff) requires the use of stobj, which takes an
2991 address on the stack instead of an array and an index. So emit
2992 the Ldelema operation for it.
2994 (EmitStoreOpcode): Use stobj for valuetypes.
2996 (UnaryMutator.EmitCode): Use the right 1 value depending on
2997 whether we are dealing with int64/uint64, float or doubles.
2999 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
3000 constructors that I implemented last night.
3002 (Constructor.IsDefault): Fix to work properly for static
3005 * cs-parser.jay (CheckDef): report method signature errors.
3006 Update error number 103 to be 132.
3008 * decl.cs: New AdditionResult enumeration value: MethodExists.
3009 Although we do this check for methods later on in the semantic
3010 analysis, catching repeated default constructors is so easy that
3011 we catch these here.
3013 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
3016 (ParameterReference.EmitAssign, Emit): handle
3019 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
3020 (ArrayAccess.EmitStoreOpcode): ditto.
3022 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
3024 * expression.cs (MakeByteBlob): Complete all the missing types
3025 (uint, short, ushort, byte, sbyte)
3027 * class.cs: Only init instance field initializers on instance
3030 Rename `constructors' to instance_constructors.
3032 (TypeContainer.AddConstructor): Only add constructors to the list
3033 if it is not static.
3035 Make sure that we handle default_static_constructor independently
3036 everywhere where we handle instance_constructors
3038 2001-12-28 Miguel de Icaza <miguel@ximian.com>
3040 * class.cs: Do not lookup or create a base initializer for a
3043 (ConstructorInitializer.Resolve): use the proper type to lookup
3046 * cs-parser.jay: Report error 1585 (modifiers between type and name).
3048 * enum.cs, interface.cs: Remove CloseType, this is taken care by
3051 * decl.cs: CloseType is now an virtual method, the default
3052 implementation just closes this type.
3054 2001-12-28 Ravi Pratap <ravi@ximian.com>
3056 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
3057 to PreserveSig by default. Also emit HideBySig on such methods.
3059 Basically, set the defaults to standard values.
3061 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
3062 argument, if candidate is better, it can't be worse than the best !
3064 (Invocation): Re-write bits to differentiate between methods being
3065 applicable in their expanded form and their normal form - for params
3068 Get rid of use_standard everywhere as only standard conversions are allowed
3069 in overload resolution.
3071 More spec conformance.
3073 2001-12-27 Miguel de Icaza <miguel@ximian.com>
3075 * driver.cs: Add --timestamp, to see where the compiler spends
3078 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
3079 `this' in static code.
3081 (SimpleName.DoResolve): Implement in terms of a helper function
3082 that allows static-references to be passed upstream to
3085 (Expression.ResolveWithSimpleName): Resolve specially simple
3086 names when called by MemberAccess to implement the special
3089 (Expression.ImplicitReferenceConversion): Handle conversions from
3090 Null to reference types before others, as Null's type is
3093 * expression.cs (Invocation.EmitCall): Handle the special case of
3094 calling methods declared on a reference type from a ValueType
3095 (Base classes System.Object and System.Enum)
3097 (MemberAccess.Resolve): Only perform lookups on Enumerations if
3098 the left hand side is a TypeExpr, not on every enumeration.
3100 (Binary.Resolve): If types are reference types, then do a cast to
3101 object on operators != and == of both arguments.
3103 * typemanager.cs (FindMembers): Extract instance and static
3104 members if requested.
3106 * interface.cs (PopulateProperty): Use void_type instead of null
3107 as the return type for the setter method.
3109 (PopulateIndexer): ditto.
3111 2001-12-27 Ravi Pratap <ravi@ximian.com>
3113 * support.cs (ReflectionParameters): Fix minor bug where we
3114 were examining the wrong parameter for the ParamArray attribute.
3116 Cope with requests for the type of the parameter at position
3117 greater than the params parameter's. We now return the element
3118 type of the params array as that makes more sense.
3120 * expression.cs (Invocation.IsParamsMethodApplicable): Update
3121 accordingly as we no longer have to extract the element type
3124 (Invocation.OverloadResolve): Update.
3126 2001-12-27 Miguel de Icaza <miguel@ximian.com>
3128 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
3129 against IEnumerator, test whether the return value is a descendant
3130 of the IEnumerator interface.
3132 * class.cs (Indexer.Define): Use an auxiliary method to implement
3133 the other bits of the method definition. Begin support for
3134 explicit interface implementation.
3136 (Property.DefineMethod): Use TypeManager.void_type instead of null
3137 for an empty return value.
3139 2001-12-26 Miguel de Icaza <miguel@ximian.com>
3141 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
3142 dealing with a FieldExpr which is composed of a FieldBuilder, in
3143 the code path we did extract the constant, but we should have
3144 obtained the underlying value to be able to cast it (otherwise we
3145 end up in an infinite loop, this is what Ravi was running into).
3147 (ArrayCreation.UpdateIndices): Arrays might be empty.
3149 (MemberAccess.ResolveMemberAccess): Add support for section
3150 14.5.4.1 that deals with the special case of E.I when E is a type
3151 and something else, that I can be a reference to a static member.
3153 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
3154 handle a particular array type to create byte blobs, it is just
3155 something we dont generate byteblobs for.
3157 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
3160 * location.cs (Push): remove the key from the hashtable that we
3161 are about to add. This happens for empty files.
3163 * driver.cs: Dispose files after we have parsed them.
3165 (tokenize): new function that only runs the tokenizer on its
3166 input, for speed testing.
3168 2001-12-26 Ravi Pratap <ravi@ximian.com>
3170 * class.cs (Event.Define): Define the private field only if there
3171 are no accessors defined.
3173 * expression.cs (ResolveMemberAccess): If there is no associated
3174 field with the event, that means we have an event defined with its
3175 own accessors and we should flag error cs0070 since transforming
3176 ourselves into a field is not valid in that case.
3178 * ecore.cs (SimpleName.DoResolve): Same as above.
3180 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
3181 and charset to sane values.
3183 2001-12-25 Ravi Pratap <ravi@ximian.com>
3185 * assign.cs (DoResolve): Perform check on events only if they
3186 are being accessed outside the declaring type.
3188 * cs-parser.jay (event_declarations): Update rules to correctly
3189 set the type of the implicit parameter etc.
3191 (add_accessor, remove_accessor): Set current local parameters.
3193 * expression.cs (Binary): For delegate addition and subtraction,
3194 cast the return value from the method into the appropriate delegate
3197 2001-12-24 Ravi Pratap <ravi@ximian.com>
3199 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
3200 of these as the workaround is unnecessary.
3202 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
3203 delegate data - none of that is needed at all.
3205 Re-write bits to extract the instance expression and the delegate method
3208 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
3211 * attribute.cs (ApplyAttributes): New method to take care of common tasks
3212 of attaching attributes instead of duplicating code everywhere.
3214 * everywhere : Update code to do attribute emission using the above method.
3216 2001-12-23 Miguel de Icaza <miguel@ximian.com>
3218 * expression.cs (IsParamsMethodApplicable): if there are not
3219 parameters, return immediately.
3221 * ecore.cs: The 0 literal can be implicity converted to an enum
3224 (SimpleName.DoResolve): First lookup the type, then lookup the
3227 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
3228 want to get its address. If the InstanceExpression is not
3229 addressable, store the result in a temporary variable, then get
3232 * codegen.cs: Only display 219 errors on warning level or above.
3234 * expression.cs (ArrayAccess): Make it implement the
3235 IMemoryLocation interface.
3237 (Binary.DoResolve): handle the operator == (object a, object b)
3238 and operator != (object a, object b) without incurring into a
3239 BoxedCast (because 5 != o should never be performed).
3241 Handle binary enumerator operators.
3243 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
3244 value type, otherwise use Ldelem_ref.
3246 Use precomputed names;
3248 (AddressOf): Implement address of
3250 * cs-parser.jay (labeled_statement): Fix recursive block
3251 addition by reworking the production.
3253 * expression.cs (New.DoEmit): New has a special case:
3255 If we are dealing with a ValueType, we have a few
3256 situations to deal with:
3258 * The target of New is a ValueType variable, that is
3259 easy, we just pass this as the variable reference
3261 * The target of New is being passed as an argument,
3262 to a boxing operation or a function that takes a
3265 In this case, we need to create a temporary variable
3266 that is the argument of New.
3269 2001-12-23 Ravi Pratap <ravi@ximian.com>
3271 * rootcontext.cs (LookupType): Check that current_type is not null before
3272 going about looking at nested types.
3274 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
3275 not implement the IAssignMethod interface any more.
3277 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
3278 where we tranform them into FieldExprs if they are being resolved from within
3281 * ecore.cs (SimpleName.DoResolve): Do the same here.
3283 * assign.cs (DoResolve, Emit): Clean up code considerably.
3285 * ../errors/bug10.cs : Add.
3287 * ../errors/cs0070.cs : Add.
3289 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
3291 * assign.cs : Get rid of EventIsLocal everywhere.
3293 2001-12-23 Miguel de Icaza <miguel@ximian.com>
3295 * ecore.cs (ConvertIntLiteral): finished the implementation.
3297 * statement.cs (SwitchLabel): Convert the value we are using as a
3298 key before looking up the table.
3300 2001-12-22 Miguel de Icaza <miguel@ximian.com>
3302 * codegen.cs (EmitTopBlock): Require a Location argument now.
3304 * cs-parser.jay (constructor_declarator): We need to setup
3305 current_local_parameters before we parse the
3306 opt_constructor_initializer, to allow the variables to be bound
3307 to the constructor arguments.
3309 * rootcontext.cs (LookupType): First lookup nested classes in our
3310 class and our parents before we go looking outside our class.
3312 * expression.cs (ConstantFold): Extract/debox the values at the
3315 * rootcontext.cs (EmitCode): Resolve the constants first before we
3316 resolve the types. This is not really needed, but it helps debugging.
3318 * statement.cs: report location.
3320 * cs-parser.jay: pass location to throw statement.
3322 * driver.cs: Small bug fix.
3324 * report.cs: Updated format to be 4-zero filled digits.
3326 2001-12-22 Ravi Pratap <ravi@ximian.com>
3328 * expression.cs (CheckIndices): Fix minor bug where the wrong
3329 variable was being referred to ;-)
3331 (DoEmit): Do not call EmitStaticInitializers when the
3332 underlying type is System.Object.
3334 2001-12-21 Ravi Pratap <ravi@ximian.com>
3336 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
3337 and do the usual workaround for SRE.
3339 * class.cs (MyEventBuilder.EventType): New member to get at the type
3340 of the event, quickly.
3342 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
3344 * assign.cs (Assign.DoResolve): Handle the case when the target
3345 is an EventExpr and perform the necessary checks.
3347 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
3350 (SimpleName.MemberStaticCheck): Include check for EventExpr.
3352 (EventExpr): Set the type in the constructor itself since we
3353 are meant to be born fully resolved.
3355 (EventExpr.Define): Revert code I wrote earlier.
3357 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
3358 instance expression is null. The instance expression is a This in that case
3359 or a null, depending on whether it is a static method or not.
3361 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
3362 refers to more than one method.
3364 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
3365 and accordingly flag errors.
3367 2001-12-21 Miguel de Icaza <miguel@ximian.com>
3369 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
3371 2001-12-22 Miguel de Icaza <miguel@ximian.com>
3373 * location.cs (ToString): Provide useful rutine.
3375 2001-12-21 Miguel de Icaza <miguel@ximian.com>
3377 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
3378 objects, return the actual integral boxed.
3380 * statement.cs (SwitchLabel): define an ILLabel for each
3383 (Switch.CheckSwitch): If the value is a Literal, extract
3384 the underlying literal.
3386 Also in the unused hashtable we had, add the SwitchLabel so we can
3387 quickly look this value up.
3389 * constant.cs: Implement a bunch of new constants. Rewrite
3390 Literal based on this. Made changes everywhere to adapt to this.
3392 * expression.cs (Expression.MakeByteBlob): Optimize routine by
3393 dereferencing array only once, and also copes with enumrations.
3395 bytes are two bytes wide, not one.
3397 (Cast): Perform constant conversions.
3399 * ecore.cs (TryImplicitIntConversion): Return literals instead of
3400 wrappers to the literals here.
3402 * expression.cs (DoNumericPromotions): long literals can converted
3403 to ulong implicity (this is taken care of elsewhere, but I was
3406 * ecore.cs (Expression.Literalize): Make the return type Literal,
3407 to improve type checking.
3409 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
3411 2001-12-20 Miguel de Icaza <miguel@ximian.com>
3413 * literal.cs: Revert code from ravi that checked the bounds. The
3414 bounds are sane by the definition of the type itself.
3416 * typemanager.cs: Fix implementation of ImplementsInterface. We
3417 need to actually look up in our parent hierarchy for interfaces
3420 * const.cs: Use the underlying type for enumerations
3422 * delegate.cs: Compute the basename for the delegate creation,
3423 that should fix the delegate test case, and restore the correct
3424 Type Lookup semantics in rootcontext
3426 * rootcontext.cs: Revert Ravi's last patch. The correct way of
3427 referencing a nested type with the Reflection API is using the "+"
3430 * cs-parser.jay: Do not require EOF token at the end.
3432 2001-12-20 Ravi Pratap <ravi@ximian.com>
3434 * rootcontext.cs (LookupType): Concatenate type names with
3435 a '.' instead of a '+' The test suite passes again.
3437 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
3438 field of the enumeration.
3440 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
3441 the case when the member is an EventExpr.
3443 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
3444 static has an associated instance expression.
3446 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
3448 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
3450 * class.cs (Event.Define): Register event and perform appropriate checks
3453 We define the Add and Remove methods even if the use provides none because
3454 in that case, we provide default implementations ourselves.
3456 Define a private field of the type of the event. This is done by the CSC compiler
3457 and we should be doing it too ;-)
3459 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
3460 More methods we use in code we generate.
3462 (multicast_delegate_type, delegate_type): Two separate types since the distinction
3465 (InitCoreTypes): Update accordingly for the above.
3467 * class.cs (Event.Emit): Generate code for default accessors that we provide
3469 (EmitDefaultMethod): Do the job in the above.
3471 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
3474 2001-12-20 Miguel de Icaza <miguel@ximian.com>
3476 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
3477 builders even if we were missing one.
3479 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
3480 pass the Basename as our class name instead of the Name. The
3481 basename will be correctly composed for us.
3483 * parameter.cs (Paramters): Now takes a Location argument.
3485 * decl.cs (DeclSpace.LookupType): Removed convenience function and
3486 make all the code call directly LookupType in RootContext and take
3487 this chance to pass the Location information everywhere.
3489 * Everywhere: pass Location information.
3491 2001-12-19 Miguel de Icaza <miguel@ximian.com>
3493 * class.cs (Constructor.Define): Updated way of detecting the
3494 length of the parameters.
3496 (TypeContainer.DefineType): Use basename as the type name for
3499 (TypeContainer.Define): Do not recursively define types here, as
3500 definition is taken care in order by the RootContext.
3502 * tree.cs: Keep track of namespaces in a per-file basis.
3504 * parameter.cs (Parameter.ComputeSignature): Update to use
3507 (Parameters.GetSignature): ditto.
3509 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
3510 instead of a TypeContainer.
3512 (Interface.SemanticAnalysis): Use `this' instead of our parent to
3513 resolve names. Because we need to be resolve in our context, not
3516 * driver.cs: Implement response files.
3518 * class.cs (TypeContainer.DefineType): If we are defined, do not
3521 (Event.Emit): Emit the code for add/remove handlers.
3522 (Event.Define): Save the MethodBuilders for add/remove.
3524 * typemanager.cs: Use pair here too.
3526 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
3527 DictionaryEntry requires the first argument to be non-null.
3529 (enum_declaration): Compute full name for registering the
3532 (delegate_declaration): Instead of using
3533 formal_parameter_list, use opt_formal_parameter_list as the list
3536 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
3537 (EventParsing): New property that controls whether `add' and
3538 `remove' are returned as tokens or identifiers (for events);
3540 2001-12-19 Ravi Pratap <ravi@ximian.com>
3542 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
3543 use MyEventBuilder only and let it wrap the real builder for us.
3545 (MyEventBuilder): Revamp constructor etc.
3547 Implement all operations that we perform on EventBuilder in precisely the same
3550 (FindMembers): Update to use the EventBuilder member.
3552 (Event.Emit): Update accordingly.
3554 2001-12-18 Ravi Pratap <ravi@ximian.com>
3556 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
3557 by calling the appropriate methods.
3559 (GetCustomAttributes): Make stubs as they cannot possibly do anything
3562 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
3564 2001-12-17 Ravi Pratap <ravi@ximian.com>
3566 * delegate.cs (Delegate.Populate): Check that the return type
3567 and various parameters types are indeed accessible.
3569 * class.cs (Constructor.Define): Same here.
3571 (Field.Define): Ditto.
3573 (Event.Define): Ditto.
3575 (Operator.Define): Check that the underlying Method defined itself
3576 correctly - so it's MethodBuilder should not be null.
3578 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
3579 expression happens to be null.
3581 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
3582 members but as of now we don't seem to be able to do anything really useful with it.
3584 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
3585 not the EventBuilder.
3587 2001-12-18 Miguel de Icaza <miguel@ximian.com>
3589 * cs-tokenizer.cs: Add support for defines.
3590 Add support for #if, #elif, #else, #endif
3592 (eval_var): evaluates a variable.
3593 (eval): stubbed for evaluating functions.
3595 * cs-parser.jay: Pass the defines information
3597 * driver.cs: Add --define command line option.
3599 * decl.cs: Move MemberCore here.
3601 Make it the base class for DeclSpace. This allows us to catch and
3602 report 108 and 109 for everything now.
3604 * class.cs (TypeContainer.Define): Extract all the members
3605 before populating and emit the warning 108 (new keyword required
3606 to override) instead of having each member implement this.
3608 (MemberCore.Define): New abstract method, we will be using this in
3609 the warning reporting engine in Populate.
3611 (Operator.Define): Adjust to new MemberCore protocol.
3613 * const.cs (Const): This does not derive from Expression, it is a
3614 temporary object we use to create fields, it is a MemberCore.
3616 * class.cs (Method.Define): Allow the entry point to be in a
3619 * driver.cs: Rewrite the argument handler to clean it up a bit.
3621 * rootcontext.cs: Made it just an auxiliary namespace feature by
3622 making everything static.
3624 * driver.cs: Adapt code to use RootContext type name instead of
3627 * delegate.cs: Remove RootContext argument.
3629 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
3632 * class.cs (Event.Define): The lookup can fail.
3634 * cs-tokenizer.cs: Begin implementation of pre-procesor.
3636 * expression.cs: Resolve the this instance before invoking the code.
3638 2001-12-17 Miguel de Icaza <miguel@ximian.com>
3640 * cs-parser.jay: Add a production in element_access that allows
3641 the thing to become a "type" reference. This way we can parse
3642 things like "(string [])" as a type.
3644 Note that this still does not handle the more complex rules of
3648 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
3650 * ecore.cs: (CopyNewMethods): new utility function used to
3651 assemble the list of methods from running FindMembers.
3653 (MemberLookup): Rework FindMembers so that
3655 2001-12-16 Miguel de Icaza <miguel@ximian.com>
3657 * class.cs (TypeContainer): Remove Delegates who fail to be
3660 * delegate.cs (Populate): Verify that we dont get null return
3661 values. TODO: Check for AsAccessible.
3663 * cs-parser.jay: Use basename to emit error 574 (destructor should
3664 have the same name as container class), not the full name.
3666 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
3667 possible representation.
3669 Also implements integer type suffixes U and L.
3671 2001-12-15 Miguel de Icaza <miguel@ximian.com>
3673 * expression.cs (ArrayCreation.DoResolve): We need to do the
3674 argument resolution *always*.
3676 * decl.cs: Make this hold the namespace. Hold the root context as
3678 (LookupType): Move here.
3680 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
3682 * location.cs (Row, Name): Fixed the code, it was always returning
3683 references to the first file.
3685 * interface.cs: Register properties defined through interfaces.
3687 * driver.cs: Add support for globbing on the command line
3689 * class.cs (Field): Make it derive from MemberCore as well.
3692 2001-12-15 Ravi Pratap <ravi@ximian.com>
3694 * class.cs (Event::Define): Check that the type of the event is a delegate
3695 type else flag error #66.
3697 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
3700 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
3701 values of EntryPoint, CharSet etc etc.
3703 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
3705 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
3706 be null and we should ignore this. I am not sure if this is really clean. Apparently,
3707 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
3708 which needs this to do its work.
3710 * ../errors/cs0066.cs : Add.
3712 2001-12-14 Miguel de Icaza <miguel@ximian.com>
3714 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
3717 * class.cs: (MethodSignature.MethodSignature): Removed hack that
3718 clears out the parameters field.
3719 (MemberSignatureCompare): Cleanup
3721 (MemberCore): New base class used to share code between MethodCore
3724 (RegisterRequiredImplementations) BindingFlags.Public requires
3725 either BindingFlags.Instace or Static. Use instance here.
3727 (Property): Refactored code to cope better with the full spec.
3729 * parameter.cs (GetParameterInfo): Return an empty array instead
3732 * class.cs (Property): Abstract or extern properties have no bodies.
3734 * parameter.cs (GetParameterInfo): return a zero-sized array.
3736 * class.cs (TypeContainer.MethodModifiersValid): Move all the
3737 method modifier validation to the typecontainer so we can reuse
3740 (MethodCore.ParameterTypes): return an empty sized array of types.
3742 (Property.Define): Test property modifier validity.
3744 Add tests for sealed/override too.
3746 (Method.Emit): abstract or extern methods have no bodies.
3748 2001-12-14 Ravi Pratap <ravi@ximian.com>
3750 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
3753 (Method::Define, ::Emit): Modify accordingly.
3755 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
3757 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
3759 * makefile: Pass in /unsafe.
3761 2001-12-13 Miguel de Icaza <miguel@ximian.com>
3763 * class.cs (MakeKey): Kill routine.
3765 * class.cs (TypeContainer.Define): Correctly define explicit
3766 method implementations (they require the full interface name plus
3769 * typemanager.cs: Deply the PtrHashtable here and stop using the
3770 lame keys. Things work so much better.
3772 This of course broke everyone who depended on `RegisterMethod' to
3773 do the `test for existance' test. This has to be done elsewhere.
3775 * support.cs (PtrHashtable): A hashtable that avoid comparing with
3776 the object stupid Equals method (because, that like fails all over
3777 the place). We still do not use it.
3779 * class.cs (TypeContainer.SetRequiredInterface,
3780 TypeContainer.RequireMethods): Killed these two routines and moved
3781 all the functionality to RegisterRequiredImplementations.
3783 (TypeContainer.RegisterRequiredImplementations): This routine now
3784 registers all the implementations required in an array for the
3785 interfaces and abstract methods. We use an array of structures
3786 which can be computed ahead of time to reduce memory usage and we
3787 also assume that lookups are cheap as most classes will not
3788 implement too many interfaces.
3790 We also avoid creating too many MethodSignatures.
3792 (TypeContainer.IsInterfaceMethod): Update and optionally does not
3793 clear the "pending" bit if we find that there are problems with
3796 (TypeContainer.VerifyPendingMethods): Update to report errors of
3797 methods that look like implementations but are not.
3799 (TypeContainer.Define): Add support for explicit interface method
3802 2001-12-12 Miguel de Icaza <miguel@ximian.com>
3804 * typemanager.cs: Keep track of the parameters here instead of
3805 being a feature of the TypeContainer.
3807 * class.cs: Drop the registration of parameters here, as
3808 InterfaceMethods are also interface declarations.
3810 * delegate.cs: Register methods with the TypeManager not only with
3811 the TypeContainer. This code was buggy.
3813 * interface.cs: Full registation here.
3815 2001-12-11 Miguel de Icaza <miguel@ximian.com>
3817 * expression.cs: Remove reducer for binary expressions, it can not
3820 * const.cs: Put here the code that used to go into constant.cs
3822 * constant.cs: Put here the code for constants, this is a new base
3825 * literal.cs: Make Literal derive from Constant.
3827 2001-12-09 Miguel de Icaza <miguel@ximian.com>
3829 * statement.cs (Return.Emit): Report error 157 if the user
3830 attempts to return from a finally block.
3832 (Return.Emit): Instead of emitting a return, jump to the end of
3835 * codegen.cs (EmitContext): ReturnValue, ReturnLabel: new
3836 LocalBuilder to store the result of the function. ReturnLabel is
3837 the target where we jump.
3840 2001-12-09 Radek Doulik <rodo@ximian.com>
3842 * cs-parser.jay: remember alias in current namespace
3844 * ecore.cs (SimpleName::DoResolve): use aliases for types or
3847 * class.cs (LookupAlias): lookup alias in my_namespace
3849 * namespace.cs (UsingAlias): add alias, namespace_or_type pair to
3851 (LookupAlias): lookup alias in this and if needed in parent
3854 2001-12-08 Miguel de Icaza <miguel@ximian.com>
3858 * rootcontext.cs: (ModuleBuilder) Made static, first step into
3859 making things static. I need this to avoid passing the
3860 TypeContainer when calling ParameterType.
3862 * support.cs (InternalParameters.ParameterType): Remove ugly hack
3863 that did string manipulation to compute the type and then call
3864 GetType. Use Parameter.ParameterType instead.
3866 * cs-tokenizer.cs: Consume the suffix for floating values.
3868 * expression.cs (ParameterReference): figure out whether this is a
3869 reference parameter or not. Kill an extra variable by computing
3870 the arg_idx during emission.
3872 * parameter.cs (Parameters.GetParameterInfo): New overloaded
3873 function that returns whether a parameter is an out/ref value or not.
3875 (Parameter.ParameterType): The type of the parameter (base,
3876 without ref/out applied).
3878 (Parameter.Resolve): Perform resolution here.
3879 (Parameter.ExternalType): The full type (with ref/out applied).
3881 * statement.cs (Using.Emit, Using.EmitExpression): Implement
3882 support for expressions on the using statement.
3884 2001-12-07 Miguel de Icaza <miguel@ximian.com>
3886 * statement.cs (Using.EmitLocalVariableDecls): Split the
3887 localvariable handling of the using statement.
3889 (Block.EmitMeta): Keep track of variable count across blocks. We
3890 were reusing slots on separate branches of blocks.
3892 (Try.Emit): Emit the general code block, we were not emitting it.
3894 Check the type of the declaration to be an IDisposable or
3895 something that can be implicity converted to it.
3897 Emit conversions if required.
3899 * ecore.cs (EmptyExpression): New utility class.
3900 (Expression.ImplicitConversionExists): New utility function.
3902 2001-12-06 Miguel de Icaza <miguel@ximian.com>
3904 * statement.cs (Using): Implement.
3906 * expression.cs (LocalVariableReference): Support read only variables.
3908 * statement.cs: Remove the explicit emit for the Leave opcode.
3909 (VariableInfo): Add a readonly field.
3911 2001-12-05 Miguel de Icaza <miguel@ximian.com>
3913 * ecore.cs (ConvCast): new class used to encapsulate the various
3914 explicit integer conversions that works in both checked and
3917 (Expression.ConvertNumericExplicit): Use new ConvCast class to
3918 properly generate the overflow opcodes.
3920 2001-12-04 Miguel de Icaza <miguel@ximian.com>
3922 * statement.cs: The correct type for the EmptyExpression is the
3923 element_type, not the variable type. Ravi pointed this out.
3925 2001-12-04 Ravi Pratap <ravi@ximian.com>
3927 * class.cs (Method::Define): Handle PInvoke methods specially
3928 by using DefinePInvokeMethod instead of the usual one.
3930 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
3931 above to do the task of extracting information and defining the method.
3933 2001-12-04 Ravi Pratap <ravi@ximian.com>
3935 * expression.cs (ArrayCreation::EmitStaticInitializers): Get rid
3936 of the condition for string type.
3938 (Emit): Move that here.
3940 (ArrayCreation::CheckIndices): Keep string literals in their expression
3943 (EmitDynamicInitializers): Handle strings appropriately.
3945 2001-12-04 Miguel de Icaza <miguel@ximian.com>
3947 * codegen.cs (EmitContext): Replace multiple variables with a
3948 single pointer to the current Switch statement.
3950 * statement.cs (GotoDefault, Switch): Adjust to cleaned up
3953 2001-12-03 Miguel de Icaza <miguel@ximian.com>
3957 * statement.cs (GotoDefault), cs-parser.jay: Implement `goto
3960 (Foreach.Emit): Foreach on arrays was not setting
3961 up the loop variables (for break/continue).
3963 (GotoCase): Semi-implented.
3965 2001-12-03 Ravi Pratap <ravi@ximian.com>
3967 * attribute.cs (CheckAttribute): Handle system attributes by using
3968 Attribute.GetAttributes to examine information we need.
3970 (GetValidPlaces): Same here.
3972 * class.cs (Method::Define): Catch invalid use of extern and abstract together.
3974 * typemanager.cs (dllimport_type): Core type for System.DllImportAttribute.
3976 * class.cs (Method.IsPinvoke): Used to determine if we are a PInvoke method.
3978 (Method::Define): Set appropriate flags if we have a DllImport attribute.
3980 (Method::Emit): Handle the case when we are a PInvoke method.

4177 2001-11-22 Miguel de Icaza <miguel@ximian.com>
4179 * statement.cs (If.Emit): Fix a bug that generated incorrect code

4190 allowed a limited set of types to be handled. Now we take a
4191 unary_expression and we resolve to a type during semantic
4194 Use the grammar productions from Rhys to handle casts (this is
4195 not complete like Rhys syntax yet, we fail to handle that corner
4196 case that C# has regarding (-x), but we will get there.
4198 2001-11-22 Ravi Pratap <ravi@ximian.com>

4215 (MemberAccess::DoResolve): Fix the code which handles Enum literals to set
4216 the correct type etc.

4240 (Expression.ConvertExplicit): Add explicit type conversions done
4243 (Expression.ImplicitNumericConversion): Oops, forgot to test for

4247 2001-11-21 Miguel de Icaza <miguel@ximian.com>
4249 * cs-parser.jay (for_statement): Reworked the way For works: now
4250 we declare manually any variables that are introduced in
4251 for_initializer to solve the problem of having out-of-band code
4252 emition (that is what got for broken).
4254 (declaration_statement): Perform the actual variable declaration
4255 that used to be done in local_variable_declaration here.
4257 (local_variable_declaration): Do not declare anything, just pass
4258 the information on a DictionaryEntry

4335 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
4336 function used to return a static Parameters structure. Used for
4337 empty parameters, as those are created very frequently.

4341 2001-11-15 Ravi Pratap <ravi@ximian.com>
4343 * interface.cs : Default modifier is private, not public. The

4346 2001-11-15 Ravi Pratap <ravi@ximian.com>
4348 * support.cs (ReflectionParameters): Fix logic to determine
4349 whether the last parameter is a params one. Test 9 passes again.

4355 of $$ to get at the location.
4357 (indexer_declaration): Similar stuff.
4361 * class.cs (Property): Register parameters for the Get and Set methods
4362 if they exist. Test 23 passes again.

4369 IndexOutOfRangeException.
4371 * class.cs (Property::Define): Register property using TypeManager.RegisterProperty

4382 2001-11-09 Miguel de Icaza <miguel@ximian.com>

4408 location where this argument is used. Notice that this is not
4409 part of the "Argument" class as to reduce the size of the
4410 structure (we know the approximate location anyways).

4413 complain with a 206.
4415 (Argument.Emit): Emit addresses of variables.
4417 (Argument.FullDesc): Simplify.

4446 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
4447 enumerations that are used in heavily used structures derive from

4450 home without adult supervision.
4452 * expression.cs (UnaryMutator): New class, used to handle ++ and
4453 -- separatedly from the other unary operators. Cleans up the
4454 code, and kills the ExpressionStatement dependency in Unary.
4456 (Unary): Removed `method' and `Arguments' from this class, making
4457 it smaller, and moving it all to SimpleCall, so I can reuse this
4458 code in other locations and avoid creating a lot of transient data
4459 strucutres when not required.
4461 * cs-parser.jay: Adjust for new changes.
4463 2001-11-11 Miguel de Icaza <miguel@ximian.com>
4465 * enum.cs (Enum.Populate): If there is a failure during

4533 * expression.cs (MemberAccess.DoResolve): Adjust code to obtain the value
4534 of a fieldinfo using the above, when dealing with a FieldBuilder.

4581 2001-11-09 Miguel de Icaza <miguel@ximian.com>
4583 * cs-parser.jay: A for_initializer if is a
4584 local_variable_declaration really ammount to have an implicit
4585 block with the variable declaration and no initializer for for.

5388 type to EmitContext.
5390 2001-10-09 Miguel de Icaza <miguel@ximian.com>

5399 * assign.cs, literal.cs, constant.cs: Update to new calling
5402 * codegen.cs: EmitContext now contains a flag indicating whether
5403 code is being generated in a static method or not.
5405 * cs-parser.jay: DecomposeQI, new function that replaces the old
5406 QualifiedIdentifier. Now we always decompose the assembled
5407 strings from qualified_identifier productions into a group of
5410 2001-10-08 Miguel de Icaza <miguel@ximian.com>
5412 * rootcontext.cs: Deal with field-less struct types correctly now
5413 by passing the size option to Define Type.
5415 * class.cs: Removed hack that created one static field.
5417 2001-10-07 Miguel de Icaza <miguel@ximian.com>
5419 * statement.cs: Moved most of the code generation here.
5421 2001-10-09 Ravi Pratap <ravi@ximian.com>
5423 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't

5432 and start performing checks according to the spec.
5434 2001-10-07 Ravi Pratap <ravi@ximian.com>
5436 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
5437 rank_specifiers instead.
5439 (rank_specifiers): Change the order in which the rank specifiers are stored
5441 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
5443 * expression.cs (ElementAccess): Implement the LValue interface too.
5445 2001-10-06 Ravi Pratap <ravi@ximian.com>
5447 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
5448 except that user defined conversions are not included.
5450 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
5451 perform the conversion of the return type, if necessary.
5453 (New::DoResolve): Check whether we are creating an array or an object
5454 and accordingly do the needful.
5456 (New::Emit): Same here.
5458 (New::DoResolve): Implement guts of array creation.

5471 * class.cs: Catch static methods having the flags override,
5472 virtual or abstract.
5474 * expression.cs (UserCast): This user cast was not really doing
5475 what it was supposed to do. Which is to be born in fully resolved
5476 state. Parts of the resolution were being performed at Emit time!
5480 2001-10-05 Miguel de Icaza <miguel@ximian.com>
5482 * expression.cs: Implicity convert the result from UserCast.
5484 2001-10-05 Ravi Pratap <ravi@ximian.com>
5486 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
5487 prevented it from working correctly.

5490 merely ConvertImplicit.
5492 2001-10-05 Miguel de Icaza <miguel@ximian.com>
5494 * typemanager.cs: Make the LookupTypeContainer function static,
5495 and not per-instance.
5497 * class.cs: Make static FindMembers (the one that takes a Type
5500 * codegen.cs: Add EmitForeach here.
5502 * cs-parser.jay: Make foreach a toplevel object instead of the
5503 inline expansion, as we need to perform semantic analysis on it.
5505 2001-10-05 Ravi Pratap <ravi@ximian.com>
5507 * expression.cs (Expression::ImplicitUserConversion): Rename to
5508 UserDefinedConversion.
5510 (Expression::UserDefinedConversion): Take an extra argument specifying
5511 whether we look for explicit user conversions too.

5522 * expression.cs (Cast): Record location info.
5524 (Expression::ConvertExplicit): Take location argument.
5526 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
5527 to determine if we are doing explicit conversions.
5529 (UserCast::Emit): Update accordingly.
5531 (Expression::ConvertExplicit): Report an error if everything fails.
5533 * ../errors/cs0030.cs : Add.
5535 2001-10-04 Miguel de Icaza <miguel@ximian.com>
5537 * modifiers.cs: If the ABSTRACT keyword is present, also set the
5538 virtual and newslot bits.
5540 * class.cs (TypeContainer::RegisterRequiredImplementations):
5541 Record methods we need.
5543 (TypeContainer::MakeKey): Helper function to make keys for
5544 MethodBases, since the Methodbase key is useless.
5546 (TypeContainer::Populate): Call RegisterRequiredImplementations
5547 before defining the methods.
5549 Create a mapping for method_builders_to_methods ahead of time
5550 instead of inside a tight loop.
5552 (::RequireMethods): Accept an object as the data to set into the
5553 hashtable so we can report interface vs abstract method mismatch.
5555 2001-10-03 Miguel de Icaza <miguel@ximian.com>
5557 * report.cs: Make all of it static.
5559 * rootcontext.cs: Drop object_type and value_type computations, as
5560 we have those in the TypeManager anyways.
5562 Drop report instance variable too, now it is a global.
5564 * driver.cs: Use try/catch on command line handling.
5566 Add --probe option to debug the error reporting system with a test
5569 * report.cs: Add support for exiting program when a probe
5570 condition is reached.
5572 2001-10-03 Ravi Pratap <ravi@ximian.com>
5574 * expression.cs (Binary::DoNumericPromotions): Fix the case when
5575 we do a forcible conversion regardless of type, to check if
5576 ForceConversion returns a null.
5578 (Binary::error19): Use location to report error.
5580 (Unary::error23): Use location here too.
5582 * ../errors/cs0019.cs : Check in.
5584 * ../errors/cs0023.cs : Check in.
5586 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
5587 case of a non-null MethodInfo object with a length of 0 !
5589 (Binary::ResolveOperator): Flag error if overload resolution fails to find
5590 an applicable member - according to the spec :-)
5591 Also fix logic to find members in base types.
5593 (Unary::ResolveOperator): Same here.
5595 (Unary::report23): Change name to error23 and make first argument a TypeContainer
5596 as I was getting thoroughly confused between this and error19 :-)
5598 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
5599 (::FindMostEncompassedType): Implement.
5600 (::FindMostEncompassingType): Implement.
5601 (::StandardConversionExists): Implement.
5603 (UserImplicitCast): Re-vamp. We now need info about most specific
5604 source and target types so that we can do the necessary conversions.
5606 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
5607 mathematical union with no duplicates.
5609 2001-10-03 Miguel de Icaza <miguel@ximian.com>
5611 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
5612 in order from base classes to child classes, so that we can in
5613 child classes look up in our parent for method names and
5614 attributes (required for handling abstract, virtual, new, override
5615 constructs: we need to instrospect our base class, and if we dont
5616 populate the classes in order, the introspection might be
5617 incorrect. For example, a method could query its parent before
5618 the parent has any methods and would determine that the parent has
5619 no abstract methods (while it could have had them)).
5621 (RootContext::CreateType): Record the order in which we define the
5624 2001-10-02 Miguel de Icaza <miguel@ximian.com>
5626 * class.cs (TypeContainer::Populate): Also method definitions can
5627 fail now, keep track of this.
5629 (TypeContainer::FindMembers): Implement support for
5630 DeclaredOnly/noDeclaredOnly flag.
5632 (Constructor::Emit) Return the ConstructorBuilder.
5634 (Method::Emit) Return the MethodBuilder.
5635 Check for abstract or virtual methods to be public.
5637 * rootcontext.cs (RootContext::CreateType): Register all the
5638 abstract methods required for the class to be complete and the
5639 interface methods that must be implemented.
5641 * cs-parser.jay: Report error 501 (method requires body if it is
5642 not marked abstract or extern).
5644 * expression.cs (TypeOf::Emit): Implement.
5646 * typemanager.cs: runtime_handle_type, new global type.
5648 * class.cs (Property::Emit): Generate code for properties.
5650 2001-10-02 Ravi Pratap <ravi@ximian.com>
5652 * expression.cs (Unary::ResolveOperator): Find operators on base type
5653 too - we now conform exactly to the spec.
5655 (Binary::ResolveOperator): Same here.
5657 * class.cs (Operator::Define): Fix minor quirk in the tests.
5659 * ../errors/cs0215.cs : Added.
5661 * ../errors/cs0556.cs : Added.
5663 * ../errors/cs0555.cs : Added.
5665 2001-10-01 Miguel de Icaza <miguel@ximian.com>
5667 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
5668 single integer which is really efficient
5670 2001-10-01 Ravi Pratap <ravi@ximian.com>
5672 * expression.cs (Expression::ImplicitUserConversion): Use location
5673 even in the case when we are examining True operators.
5675 * class.cs (Operator::Define): Perform extensive checks to conform
5676 with the rules for operator overloading in the spec.
5678 * expression.cs (Expression::ImplicitReferenceConversion): Implement
5679 some of the other conversions mentioned in the spec.
5681 * typemanager.cs (array_type): New static member for the System.Array built-in
5684 (cloneable_interface): For System.ICloneable interface.
5686 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
5687 we start resolving the tree and populating types.
5689 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
5691 2001-10-01 Miguel de Icaza <miguel@ximian.com>
5693 * expression.cs (Expression::ExprClassFromMemberInfo,
5694 Expression::Literalize): Create literal expressions from
5695 FieldInfos which are literals.
5697 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
5698 type casts, because they were wrong. The test suite in tests
5701 (ImplicitNumericConversion): ushort to ulong requires a widening
5704 Int32 constant to long requires widening cast as well.
5706 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
5707 for integers because the type on the stack is not i4.
5709 2001-09-30 Miguel de Icaza <miguel@ximian.com>
5711 * expression.cs (report118): require location argument.
5713 * parameter.cs: Do not dereference potential null value.
5715 * class.cs: Catch methods that lack the `new' keyword when
5716 overriding a name. Report warnings when `new' is used without
5717 anything being there to override.
5719 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
5721 * class.cs: Only add constructor to hashtable if it is non-null
5722 (as now constructors can fail on define).
5724 (TypeManager, Class, Struct): Take location arguments.
5726 Catch field instance initialization in structs as errors.
5728 accepting_filter: a new filter for FindMembers that is static so
5729 that we dont create an instance per invocation.
5731 (Constructor::Define): Catch errors where a struct constructor is
5734 * cs-parser.jay: Pass location information for various new
5737 * delegate.cs (Delegate): take a location argument.
5739 * driver.cs: Do not call EmitCode if there were problesm in the
5740 Definition of the types, as many Builders wont be there.
5742 * decl.cs (Decl::Decl): Require a location argument.
5744 * cs-tokenizer.cs: Handle properly hex constants that can not fit
5745 into integers, and find the most appropiate integer for it.
5747 * literal.cs: Implement ULongLiteral.
5749 * rootcontext.cs: Provide better information about the location of
5750 failure when CreateType fails.
5752 2001-09-29 Miguel de Icaza <miguel@ximian.com>
5754 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
5757 * expression.cs (Binary::CheckShiftArguments): Add missing type
5759 (Binary::ResolveOperator): Add type to the logical and and logical
5760 or, Bitwise And/Or and Exclusive Or code paths, it was missing
5763 (Binary::DoNumericPromotions): In the case where either argument
5764 is ulong (and most signed types combined with ulong cause an
5765 error) perform implicit integer constant conversions as well.
5767 2001-09-28 Miguel de Icaza <miguel@ximian.com>
5769 * expression.cs (UserImplicitCast): Method should always be
5771 (Invocation::BetterConversion): Simplified test for IntLiteral.
5773 (Expression::ImplicitNumericConversion): Split this routine out.
5774 Put the code that performs implicit constant integer conversions
5777 (Expression::Resolve): Become a wrapper around DoResolve so we can
5778 check eclass and type being set after resolve.
5780 (Invocation::Badness): Remove this dead function
5782 (Binary::ResolveOperator): Do not compute the expensive argumnets
5783 unless we have a union for it.
5785 (Probe::Emit): Is needs to do an isinst and then
5786 compare against null.
5788 (::CanConvert): Added Location argument. If the Location argument
5789 is null (Location.Null), then we do not report errors. This is
5790 used by the `probe' mechanism of the Explicit conversion. We do
5791 not want to generate an error for something that the user
5792 explicitly requested to be casted. But the pipeline for an
5793 explicit cast first tests for potential implicit casts.
5795 So for now, if the Location is null, it means `Probe only' to
5796 avoid adding another argument. Might have to revise this
5799 (ClassCast): New class used to type cast objects into arbitrary
5800 classes (used in Explicit Reference Conversions).
5802 Implement `as' as well.
5804 Reverted all the patches from Ravi below: they were broken:
5806 * The use of `level' as a mechanism to stop recursive
5807 invocations is wrong. That was there just to catch the
5808 bug with a strack trace but not as a way of addressing
5811 To fix the problem we have to *understand* what is going
5812 on and the interactions and come up with a plan, not
5813 just get things going.
5815 * The use of the type conversion cache that I proposed
5816 last night had an open topic: How does this work across
5817 protection domains. A user defined conversion might not
5818 be public in the location where we are applying the
5819 conversion, a different conversion might be selected
5820 (ie, private A->B (better) but public B->A (worse),
5821 inside A, A->B applies, but outside it, B->A will
5824 * On top of that (ie, even if the above is solved),
5825 conversions in a cache need to be abstract. Ie, `To
5826 convert from an Int to a Short use an OpcodeCast', not
5827 `To convert from an Int to a Short use the OpcodeCast on
5828 the variable 5' (which is what this patch was doing).
5830 2001-09-28 Ravi Pratap <ravi@ximian.com>
5832 * expression.cs (Invocation::ConversionExists): Re-write to use
5833 the conversion cache
5835 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
5836 cache all conversions done, not just user-defined ones.
5838 (Invocation::BetterConversion): The real culprit. Use ConversionExists
5839 to determine if a conversion exists instead of acutually trying to
5840 perform the conversion. It's faster too.
5842 (Expression::ConvertExplicit): Modify to use ConversionExists to check
5843 and only then attempt the implicit conversion.
5845 2001-09-28 Ravi Pratap <ravi@ximian.com>
5847 * expression.cs (ConvertImplicit): Use a cache for conversions
5848 already found. Check level of recursion and bail out if necessary.
5850 2001-09-28 Miguel de Icaza <miguel@ximian.com>
5852 * typemanager.cs (string_concat_string_string, string_concat_object_object):
5853 Export standard methods that we expect for string operations.
5855 * statement.cs (Block::UsageWarning): Track usage of variables and
5856 report the errors for not used variables.
5858 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
5861 2001-09-27 Miguel de Icaza <miguel@ximian.com>
5863 * codegen.cs: remove unnneded code
5865 * expression.cs: Removed BuiltinTypeAccess class
5867 Fix the order in which implicit conversions are
5870 The previous fixed dropped support for boxed conversions (adding a
5871 test to the test suite now)
5873 (UserImplicitCast::CanConvert): Remove test for source being null,
5874 that code is broken. We should not feed a null to begin with, if
5875 we do, then we should track the bug where the problem originates
5876 and not try to cover it up here.
5878 Return a resolved expression of type UserImplicitCast on success
5879 rather than true/false. Ravi: this is what I was talking about,
5880 the pattern is to use a static method as a "constructor" for
5883 Also, do not create arguments until the very last minute,
5884 otherwise we always create the arguments even for lookups that
5885 will never be performed.
5887 (UserImplicitCast::Resolve): Eliminate, objects of type
5888 UserImplicitCast are born in a fully resolved state.
5890 * typemanager.cs (InitCoreTypes): Init also value_type
5893 * expression.cs (Cast::Resolve): First resolve the child expression.
5895 (LValue): Add new method AddressOf to be used by
5898 Change the argument of Store to take an EmitContext instead of an
5899 ILGenerator, because things like FieldExpr need to be able to call
5900 their children expression to generate the instance code.
5902 (Expression::Error, Expression::Warning): Sugar functions for
5905 (Expression::MemberLookup): Accept a TypeContainer instead of a
5906 Report as the first argument.
5908 (Expression::ResolvePrimary): Killed. I still want to improve
5909 this as currently the code is just not right.
5911 (Expression::ResolveMemberAccess): Simplify, but it is still
5914 (Unary::Resolve): Catch errors in AddressOf operators.
5916 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
5917 index to a byte for the short-version, or the compiler will choose
5918 the wrong Emit call, which generates the wrong data.
5920 (ParameterReference::Emit, ::Store): same.
5922 (FieldExpr::AddressOf): Implement.
5924 * typemanager.cs: TypeManager: made public variable instead of
5927 * driver.cs: document --fatal.
5929 * report.cs (ErrorMessage, WarningMessage): new names for the old
5930 Error and Warning classes.
5932 * cs-parser.jay (member_access): Turn built-in access to types
5933 into a normal simplename
5935 2001-09-27 Ravi Pratap <ravi@ximian.com>
5937 * expression.cs (Invocation::BetterConversion): Fix to cope
5938 with q being null, since this was introducing a bug.
5940 * expression.cs (ConvertImplicit): Do built-in conversions first.
5942 2001-09-27 Ravi Pratap <ravi@ximian.com>
5944 * expression.cs (UserImplicitCast::Resolve): Fix bug.
5946 2001-09-27 Ravi Pratap <ravi@ximian.com>
5948 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
5949 I had introduced long ago (what's new ?).
5951 * expression.cs (UserImplicitCast::CanConvert): Static method to do
5952 the work of all the checking.
5953 (ConvertImplicit): Call CanConvert and only then create object if necessary.
5954 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
5956 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
5957 that is the right way.
5959 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
5960 overloading resolution. Use everywhere instead of cutting and pasting code.
5962 (Binary::ResolveOperator): Use MakeUnionSet.
5964 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
5965 we have to convert to bool types. Not complete yet.
5967 2001-09-27 Miguel de Icaza <miguel@ximian.com>
5969 * typemanager.cs (TypeManager::CSharpName): support ushort.
5971 * expression.cs (Expression::TryImplicitIntConversion): Attempts
5972 to provide an expression that performsn an implicit constant int
5973 conversion (section 6.1.6).
5974 (Expression::ConvertImplicitRequired): Reworked to include
5975 implicit constant expression conversions.
5977 (Expression::ConvertNumericExplicit): Finished.
5979 (Invocation::Emit): If InstanceExpression is null, then it means
5980 that we perform a call on this.
5982 2001-09-26 Miguel de Icaza <miguel@ximian.com>
5984 * expression.cs (Unary::Emit): Remove some dead code.
5985 (Probe): Implement Resolve and Emit for `is'.
5986 (Expression::ConvertImplicitRequired): Attempt to do constant
5987 expression conversions here. Maybe should be moved to
5988 ConvertImplicit, but I am not sure.
5989 (Expression::ImplicitLongConstantConversionPossible,
5990 Expression::ImplicitIntConstantConversionPossible): New functions
5991 that tell whether is it possible to apply an implicit constant
5992 expression conversion.
5994 (ConvertNumericExplicit): Started work on explicit numeric
5997 * cs-parser.jay: Update operator constants.
5999 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
6000 (Parameters::GetSignature): Hook up VerifyArgs here.
6001 (Parameters::VerifyArgs): Verifies that no two arguments have the
6004 * class.cs (Operator): Update the operator names to reflect the
6005 ones that the spec expects (as we are just stringizing the
6008 * expression.cs (Unary::ResolveOperator): Fix bug: Use
6009 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
6010 previous usage did only work for our methods.
6011 (Expression::ConvertImplicit): Handle decimal implicit numeric
6012 conversions as well.
6013 (Expression::InternalTypeConstructor): Used to invoke constructors
6014 on internal types for default promotions.
6016 (Unary::Emit): Implement special handling for the pre/post
6017 increment/decrement for overloaded operators, as they need to have
6018 the same semantics as the other operators.
6020 (Binary::ResolveOperator): ditto.
6021 (Invocation::ConversionExists): ditto.
6022 (UserImplicitCast::Resolve): ditto.
6024 2001-09-26 Ravi Pratap <ravi@ximian.com>
6026 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded
6027 operator, return after emitting body. Regression tests pass again !
6029 * expression.cs (ConvertImplicit): Take TypeContainer as first argument
6030 (Unary::ForceConversion, Binary::ForceConversion): Ditto.
6031 (Invocation::OverloadResolve): Ditto.
6032 (Invocation::BetterFunction, BetterConversion, ConversionExists): Ditto.
6034 * everywhere : update calls to the above methods accordingly.
6036 2001-09-26 Miguel de Icaza <miguel@ximian.com>
6038 * assign.cs (Assign): Make it inherit from ExpressionStatement.
6040 * expression.cs (ExpressionStatement): New base class used for
6041 expressions that can appear in statements, so that we can provide
6042 an alternate path to generate expression that do not leave a value
6045 (Expression::Emit, and all the derivatives): We no longer return
6046 whether a value is left on the stack or not. Every expression
6047 after being emitted leaves a single value on the stack.
6049 * codegen.cs (EmitContext::EmitStatementExpression): Use the
6050 facilties of ExpressionStatement if possible.
6052 * cs-parser.jay: Update statement_expression.
6054 2001-09-25 Miguel de Icaza <miguel@ximian.com>
6056 * driver.cs: Change the wording of message
6058 2001-09-25 Ravi Pratap <ravi@ximian.com>
6060 * expression.cs (Binary::ResolveOperator): Had forgottten to set
6061 the type of the expression to the return type of the method if
6062 we have an overloaded operator match ! The regression tests pass again !
6063 (Unary::ResolveOperator): Ditto.
6065 * expression.cs (Invocation::ConversionExists): Correct the member lookup
6066 to find "op_Implicit", not "implicit" ;-)

6143 * typemanager.cs: declare and load enum_type, delegate_type and
6146 * expression.cs (Expression::Emit): Now emit returns a value that

6252 (Unary::ForceConversion): Copy and Paste !
6254 * class.cs (Operator::Define): Fix a small bug for the case when we have
6257 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
6258 for the inbuilt operators. Only overloading works for now ;-)
6260 2001-09-18 Miguel de Icaza <miguel@ximian.com>
6262 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
6263 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

6276 (FieldExpr::Emit): Implement.
6278 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
6279 the last instruction contains a return opcode to avoid generating
6280 the last `ret' instruction (this generates correct code, and it is
6281 nice to pass the peverify output).
6283 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
6284 initializer for static and instance variables.
6285 (Constructor::Emit): Allow initializer to be null in the case of
6286 static constructors. Only emit initializer for instance

6299 * driver.cs: Stop compilation if there are parse errors.
6301 * cs-parser.jay (constructor_declaration): Provide default base

6304 initializers if none was specified.
6305 Catch the fact that constructors should not have parameters.
6307 * class.cs: Do not emit parent class initializers for static
6308 constructors, that should be flagged as an error.
6310 2001-09-18 Ravi Pratap <ravi@ximian.com>
6312 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.

6342 (Expression::MemberLookup): Provide a version that allows to
6343 specify the MemberTypes and BindingFlags.
6345 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
6346 so it was not fetching variable information from outer blocks.
6348 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
6349 Beforefieldinit as it was buggy.
6351 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
6354 * class.cs (Constructor::Emit): Only emit if block is not null.

6448 * modifiers.cs: Do not use `parent', instead use the real type
6449 container to evaluate permission settings.

6461 * driver.cs: Added --parse option that only parses its input files
6464 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
6465 incorrect. IsTopLevel is not used to tell whether an object is
6466 root_types or not (that can be achieved by testing this ==
6467 root_types). But to see if this is a top-level *class* (not
6468 necessarly our "toplevel" container).
6470 2001-09-14 Ravi Pratap <ravi@ximian.com>
6472 * enum.cs (Enum::Define): Modify to call the Lookup method on the

6478 Modifiers.TypeAttr. This should just be a call to that method.

6488 * modifiers.cs (FieldAttr): Re-write.

6491 (TypeContainer::HaveStaticConstructor): New property to provide access
6492 to precisely that info.
6494 * modifiers.cs (MethodAttr): Re-write.
6495 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
6497 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent

6500 2001-09-13 Miguel de Icaza <miguel@ximian.com>
6502 * expression.cs (MemberLookup): Fruitless attempt to lookup
6503 constructors. Maybe I need to emit default constructors? That

6505 (Invocation::OverloadResolve): Cope with Arguments == null.
6506 (Invocation::EmitArguments): new function, shared by the new
6508 (Invocation::Emit): Handle static and instance methods. Emit
6509 proper call instruction for virtual or non-virtual invocations.

6528 objects that we might have around.
6530 (Populate): Only initialize method_builders_to_methods once.
6532 * expression.cs (PropertyExpr): Initialize type from the
6535 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

6540 (Binary::ResolveOperator): Set the return type to boolean for
6541 comparission operators
6543 * typemanager.cs: Remove debugging print code.
6545 (Invocation::Resolve): resolve type.
6547 * class.cs: Allocate a MemberInfo of the correct size, as the code
6548 elsewhere depends on the test to reflect the correct contents.
6550 (Method::) Keep track of parameters, due to System.Reflection holes
6552 (TypeContainer::Populate): Keep track of MethodBuilders to Method
6555 (TypeContainer::FindMembers): Use ArrayList and then copy an array
6556 of the exact size and return that.
6558 (Class::LookupMethodByBuilder): New function that maps
6559 MethodBuilders to its methods. Required to locate the information
6560 on methods because System.Reflection bit us again.
6562 * support.cs: New file, contains an interface ParameterData and
6563 two implementations: ReflectionParameters and InternalParameters
6564 used to access Parameter information. We will need to grow this
6567 * expression.cs (Invocation::GetParameterData): implement a cache
6568 and a wrapper around the ParameterData creation for methods.
6569 (Invocation::OverloadResolve): Use new code.
6571 2001-09-13 Ravi Pratap <ravi@ximian.com>

6576 (TypeContainer::Populate): Update accordingly.
6577 (TypeContainer::FindMembers): Implement.
6579 2001-09-13 Miguel de Icaza <miguel@ximian.com>
6581 * statement.cs: (VariableInfo::VariableType): New field to be
6582 initialized with the full type once it is resolved.
6584 2001-09-12 Miguel de Icaza <miguel@ximian.com>

6625 2001-09-12 Ravi Pratap <ravi@ximian.com>
6627 * class.cs (TypeContainer::FindMembers): Method which does exactly
6628 what Type.FindMembers does, only we don't have to use reflection. No
6631 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
6632 typecontainer objects as we need to get at them.
6633 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.
6635 * rootcontext.cs : Correspondingly modify called to AddUserType to pass the
6636 typecontainer object.
6638 * expression.cs (MemberLookup): Modify signature to take a RootContext object instead
6639 of just a Report object.
6641 2001-09-11 Ravi Pratap <ravi@ximian.com>

6660 (Event::Define): Ditto.
6661 (Property::Define): Ditto.
6663 2001-09-10 Ravi Pratap <ravi@ximian.com>

6668 (Operator.OperatorMethodBuilder): New member to hold the method builder
6669 for the operator we are defining.

6675 addOn_ and removeOn_
6677 * genericparser.cs (GenericParser::error): Overloaded method to handle the case

6728 already might have something already fully qualified like
6729 'System.Console.WriteLine'

6880 will is used during the tree rewriting as we resolve them during
6883 (Expression::MemberLookup): Implements the MemberLookup (7.3) from
6884 the spec. Missing entirely is the information about
6885 accessability of elements of it.

7056 and re-write the code in the actions to extract the specific and
7057 general catch clauses by being a little smart ;-)
7059 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
7060 Hooray, try and catch statements parse fine !
7062 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
7064 * statement.cs (Block::GetVariableType): Fix logic to extract the type
7065 string from the hashtable of variables.
7067 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did

7069 (catch_clauses): Fixed gross error which made Key and Value of the
7070 DictionaryEntry the same : $1 !!
7072 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
7074 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
7076 * cs-parser.jay (event_declaration): Correct to remove the semicolon

7083 (indexer_declarator): Implement actions.
7084 (parsing_indexer): New local boolean used to keep track of whether

7112 concatenating all the commas together, just as they appear.
7113 (opt_dim_separators): Modify accordingly

7118 instead of ignoring the rank_specifiers.
7119 (expression_list): Implement to collect the expressions

7145 * typemanager.cs (InitCoreTypes): Initialize the various core
7146 types after we have populated the type manager with the user
7147 defined types (this distinction will be important later while
7148 compiling corlib.dll)
7150 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
7151 on Expression Classification. Now all expressions have a method
7152 `Resolve' and a method `Emit'.
7154 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
7155 generation from working. Also add some temporary debugging
7158 2001-08-24 Miguel de Icaza <miguel@ximian.com>
7160 * codegen.cs: Lots of code generation pieces. This is only the
7161 beginning, will continue tomorrow with more touches of polish. We
7162 handle the fundamentals of if, while, do, for, return. Others are

7165 * gen-treedump.cs: Bug fix, use s.Increment here instead of
7168 * codegen.cs (EmitContext): New struct, used during code
7169 emission to keep a context. Most of the code generation will be

7192 move from Properties to public readonly fields.
7193 (Method::ParameterTypes): Returns the parameter types for the
7194 function, and implements a cache that will be useful later when I
7195 do error checking and the semantic analysis on the methods is
7197 (Constructor::GetCallingConvention): Renamed from CallingConvetion
7198 and made a method, optional argument tells whether this is a class
7199 or a structure to apply the `has-this' bit.
7200 (Method::GetCallingConvention): Implement, returns the calling
7202 (Method::Define): Defines the type, a second pass is performed
7203 later to populate the methods.

7225 and the default static constructor.
7227 (Constructor::) Another class that starts using `public readonly'
7228 instead of properties.
7230 (Constructor::IsDefault): Whether this is a default constructor.
7232 (Field::) use readonly public fields instead of properties also.
7234 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
7235 track of static constructors; If none is used, turn on
7236 BeforeFieldInit in the TypeAttributes.
7238 * cs-parser.jay (opt_argument_list): now the return can be null
7239 for the cases where there are no arguments.
7241 (constructor_declarator): If there is no implicit `base' or
7242 `this', then invoke the default parent constructor.
7244 * modifiers.cs (MethodAttr): New static function maps a set of
7245 modifiers flags into a MethodAttributes enum
7246 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
7247 MethodAttr, TypeAttr to represent the various mappings where the
7249 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
7251 2001-08-19 Miguel de Icaza <miguel@ximian.com>

7268 `public readonly' fields.
7270 2001-08-16 Miguel de Icaza <miguel@ximian.com>
7272 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
7273 initialize their hashtables/arraylists only when they are needed
7274 instead of doing this always.
7276 * parameter.cs: Handle refs and out parameters.
7278 * cs-parser.jay: Use an ArrayList to construct the arguments
7279 instead of the ParameterCollection, and then cast that to a
7282 * parameter.cs: Drop the use of ParameterCollection and use
7283 instead arrays of Parameters.
7285 (GetParameterInfo): Use the Type, not the Name when resolving
7288 2001-08-13 Miguel de Icaza <miguel@ximian.com>

7305 this System.Reflection code is. Kudos to Microsoft
7307 * typemanager.cs: Implement a type cache and avoid loading all
7308 types at boot time. Wrap in LookupType the internals. This made
7309 the compiler so much faster. Wow. I rule!
7311 * driver.cs: Make sure we always load mscorlib first (for
7312 debugging purposes, nothing really important).
7314 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
7315 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
7317 * rootcontext.cs: Lookup types on their namespace; Lookup types
7318 on namespaces that have been imported using the `using' keyword.
7320 * class.cs (TypeContainer::TypeAttr): Virtualize.
7321 (Class::TypeAttr): Return attributes suitable for this bad boy.
7322 (Struct::TypeAttr): ditto.
7323 Handle nested classes.

7333 Drop use of TypeRefs, and use strings instead.
7335 2001-08-04 Miguel de Icaza <miguel@ximian.com>
7339 * class.cs (Struct::Struct): set the SEALED flags after
7340 checking the modifiers.
7341 (TypeContainer::TypeAttr): new property, returns the
7342 TypeAttributes for a class.
7344 * cs-parser.jay (type_list): Oops, list production was creating a
7345 new list of base types.
7347 * rootcontext.cs (StdLib): New property.
7348 (GetInterfaceTypeByName): returns an interface by type name, and
7349 encapsulates error handling here.
7350 (GetInterfaces): simplified.
7351 (ResolveTree): Encapsulated all the tree resolution here.
7352 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
7355 * driver.cs: Add support for --nostdlib, to avoid loading the
7357 (Main): Do not put tree resolution here.
7359 * rootcontext.cs: Beginning of the class resolution.
7361 2001-08-03 Miguel de Icaza <miguel@ximian.com>
7363 * rootcontext.cs: Provide better error reporting.
7365 * cs-parser.jay (interface_base): set our $$ to be interfaces.
7367 * rootcontext.cs (CreateInterface): Handle the case where there
7368 are no parent interfaces.
7370 (CloseTypes): Routine to flush types at the end.
7371 (CreateInterface): Track types.
7372 (GetInterfaces): Returns an array of Types from the list of
7375 * typemanager.c (AddUserType): Mechanism to track user types (puts
7376 the type on the global type hash, and allows us to close it at the
7379 2001-08-02 Miguel de Icaza <miguel@ximian.com>
7381 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
7382 RecordInterface instead.
7384 * cs-parser.jay: Updated to reflect changes above.
7386 * decl.cs (Definition): Keep track of the TypeBuilder type that
7387 represents this type here. Not sure we will use it in the long
7388 run, but wont hurt for now.
7390 * driver.cs: Smaller changes to accomodate the new code.
7392 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
7395 * rootcontext.cs (CreateInterface): New method, used to create
7396 the System.TypeBuilder type for interfaces.
7397 (ResolveInterfaces): new entry point to resolve the interface
7399 (CodeGen): Property, used to keep track of the code generator.
7401 2001-07-26 Miguel de Icaza <miguel@ximian.com>
7403 * cs-parser.jay: Add a second production for delegate_declaration
7406 (enum_body): Put an opt_comma here instead of putting it on
7407 enum_body or enum_member_declarations so we can handle trailing
7408 commas on enumeration members. Gets rid of a shift/reduce.
7410 (type_list): Need a COMMA in the middle.
7412 (indexer_declaration): Tell tokenizer to recognize get/set
7414 * Remove old targets.
7416 * Re-add the parser target.
7418 2001-07-13 Simon Cozens <simon@simon-cozens.org>
7420 * cs-parser.jay: Add precendence rules for a number of operators
7421 ot reduce the number of shift/reduce conflicts in the grammar.
7423 2001-07-17 Miguel de Icaza <miguel@ximian.com>
7425 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
7428 Get rid of old crufty code.
7430 * rootcontext.cs: Use this to keep track of the parsed
7431 representation and the defined types available to the program.
7433 * gen-treedump.cs: adjust for new convention.
7435 * type.cs: Split out the type manager, and the assembly builder
7438 * typemanager.cs: the type manager will live here now.

7442 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
7444 * makefile: Fixed up for easy making.
7446 2001-07-13 Simon Cozens <simon@simon-cozens.org>
7448 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
7451 (unary_expression): Expand pre_increment_expression and
7452 post_decrement_expression to reduce a shift/reduce.
7454 2001-07-11 Simon Cozens
7456 * cs-tokenizer.cs: Hex numbers should begin with a 0.
7458 Improve allow_keyword_as_indent name.
7460 2001-06-19 Miguel de Icaza <miguel@ximian.com>
7462 * Adjustments for Beta2.
7464 2001-06-13 Miguel de Icaza <miguel@ximian.com>
7466 * decl.cs: Added `Define' abstract method.
7467 (InTransit): new property, used to catch recursive definitions.
7469 * interface.cs: Implement `Define'.
7471 * modifiers.cs: Map Modifiers.constants to
7472 System.Reflection.TypeAttribute flags.
7474 * class.cs: Keep track of types and user-defined types.
7475 (BuilderInit): New method for creating an assembly
7476 (ResolveType): New function to launch the resolution process, only
7477 used by interfaces for now.
7479 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
7480 that are inserted into the name space.
7482 2001-06-08 Miguel de Icaza <miguel@ximian.com>
7484 * ARGH. I have screwed up my tree so many times due to the use of
7485 rsync rather than using CVS. Going to fix this at once.
7487 * driver.cs: Objetify driver. Load assemblies, use assemblies to
7490 2001-06-07 Miguel de Icaza <miguel@ximian.com>
7492 * Experiment successful: Use System.Type rather that our own
7495 2001-05-25 Miguel de Icaza <miguel@ximian.com>
7497 * cs-parser.jay: Removed nsAliases from here.
7499 Use new namespaces, handle `using XXX;'
7501 * namespace.cs: Reimplemented namespace handling, use a recursive
7502 definition of the class. Now we can keep track of using clauses
7503 and catch invalid using clauses.
7505 2001-05-24 Miguel de Icaza <miguel@ximian.com>
7507 * gen-treedump.cs: Adapted for all the renaming.
7509 * expression.cs (Expression): this class now has a Type property
7510 which returns an expression Type.
7512 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
7513 `Type', as this has a different meaning now in the base
7515 2001-05-22 Miguel de Icaza <miguel@ximian.com>
7517 * interface.cs, class.cs: Removed from all the sources the
7518 references to signature computation, as we can not do method
7519 signature computation during the parsing time, as we are not
7520 trying to solve at that point distinguishing:
7524 void a (NS.Blah x) {}
7527 Which depending on the context might be valid or not, as we do not
7528 know if Blah is the same thing as NS.Blah at that point.
7530 * Redid everything so the code uses TypeRefs now instead of
7531 Types. TypeRefs are just temporary type placeholders, that need
7532 to be resolved. They initially have a pointer to a string and the
7533 current scope in which they are used. This is used later by the
7534 compiler to resolve the reference to an actual Type.
7536 * DeclSpace is no longer a CIR.Type, and neither are
7537 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
7538 are all DeclSpaces, but no Types.
7540 * type.cs (TypeRefManager): This implements the TypeRef manager,
7541 which keeps track of all the types that need to be resolved after
7542 the parsing has finished.
7544 2001-05-13 Miguel de Icaza <miguel@ximian.com>
7546 * ARGH. We are going to have to store `foreach' as a class rather
7547 than resolving it, as we need to verify error 1579 after name
7548 resolution. *OR* we could keep a flag that says `This request to
7549 IEnumerator comes from a foreach statement' which we can then use
7550 to generate the error.
7552 2001-05-10 Miguel de Icaza <miguel@ximian.com>
7554 * class.cs (TypeContainer.AddMethod): we now add methods to the
7555 MethodGroup instead of the method hashtable.
7557 * expression.cs: Add MethodGroup abstraction, which gets us one
7558 step closer to the specification in the way we handle method
7561 * cs-parser.jay (primary_expression): qualified_identifier now
7562 tried to match up an identifier to a local variable reference or
7563 to a parameter reference.
7565 current_local_parameters is now a parser global variable that
7566 points to the current parameters for the block, used during name
7569 (property_declaration): Now creates an implicit `value' argument to
7572 2001-05-09 Miguel de Icaza <miguel@ximian.com>
7574 * parameter.cs: Do not use `param' arguments as part of the
7575 signature, per the spec.
7577 2001-05-08 Miguel de Icaza <miguel@ximian.com>
7579 * decl.cs: Base class for classes, structs and interfaces. This
7580 is the "Declaration Space"
7582 * cs-parser.jay: Use CheckDef for checking declaration errors
7583 instead of having one on each function.
7585 * class.cs: Factor out some code for handling error handling in
7586 accordance to the "Declarations" section in the "Basic Concepts"
7587 chapter in the ECMA C# spec.
7589 * interface.cs: Make all interface member classes derive from
7590 InterfaceMemberBase.
7592 2001-05-07 Miguel de Icaza <miguel@ximian.com>
7594 * Many things: all interfaces are parsed and generated in
7595 gen-treedump. Support for member variables, constructors,
7596 destructors, properties, constants is there.
7598 Beginning of the IL backend, but very little done, just there for
7601 2001-04-29 Miguel de Icaza <miguel@ximian.com>
7603 * cs-parser.jay: Fix labeled statement.
7605 * cs-tokenizer.cs (escape): Escape " and ' always.
7606 ref_line, ref_name: keep track of the line/filename as instructed
7607 by #line by the compiler.
7610 2001-04-27 Miguel de Icaza <miguel@ximian.com>
7612 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
7613 to match the values in System.CodeDOM.
7615 Divid renamed to Divide.
7617 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
7619 (Statements.set): remove.
7621 * System.CodeDOM/CodeCatchClause.cs: always have a valid
7624 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
7625 falseStatements always have valid values.
7627 * cs-parser.jay: Use System.CodeDOM now.
