1 2002-07-19 Martin Baulig <martin@gnome.org>
3 * expression.cs (New.DoEmit): Create a new LocalTemporary each time
4 this function is called, it's not allowed to share LocalBuilders
7 2002-07-19 Martin Baulig <martin@gnome.org>
9 * expression.cs (Argument.Resolve): Report an error 118 when trying
10 to pass a type as argument.
12 2002-07-18 Martin Baulig <martin@gnome.org>
14 * ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
15 Conv_R_Un for the signed `long' type.
17 2002-07-15 Miguel de Icaza <miguel@ximian.com>
19 * expression.cs (MemberAccess.DoResolve): Do not reuse the field
20 `expr' for the temporary result, as that will fail if we do
21 multiple resolves on the same expression.
23 2002-07-05 Miguel de Icaza <miguel@ximian.com>
25 * ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
26 ec.TypeContainer for looking up aliases.
28 * class.cs (TypeContainer): Remove LookupAlias from here.
30 * decl.cs (DeclSpace); Move here.
32 2002-07-01 Miguel de Icaza <miguel@ximian.com>
34 * class.cs (FindMembers): Only call filter if the constructor
37 Also handle delegates in `NestedTypes' now. Now we will perform
38 type lookups using the standard resolution process. This also
41 * decl.cs (DeclSpace.ResolveType): New type resolution routine.
42 This uses Expressions (the limited kind that can be parsed by the
43 tree) instead of strings.
45 * expression.cs (ComposedCast.ToString): Implement, used to flag
46 errors since now we have to render expressions.
48 (ArrayCreation): Kill FormElementType. Use ComposedCasts in
51 * ecore.cs (SimpleName.ToString): ditto.
53 * cs-parser.jay: Instead of using strings to assemble types, use
54 Expressions to assemble the type (using SimpleName, ComposedCast,
55 MemberAccess). This should fix the type lookups in declarations,
56 because we were using a different code path for this.
58 * statement.cs (Block.Resolve): Continue processing statements
59 even when there is an error.
61 2002-07-17 Miguel de Icaza <miguel@ximian.com>
63 * class.cs (Event.Define): Also remove the `remove' method from
64 the list of pending items.
66 * expression.cs (ParameterReference): Use ldarg.N (0..3) to
67 generate more compact code.
69 2002-07-17 Martin Baulig <martin@gnome.org>
71 * const.cs (Const.LookupConstantValue): Add support for constant
72 `unchecked' and `checked' expressions.
73 Also adding test case test-140.cs for this.
75 2002-07-17 Martin Baulig <martin@gnome.org>
77 * statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
78 check whether mi.ReturnType implements the IEnumerator interface; the
79 `==' and the IsAssignableFrom() will fail in this situation.
81 2002-07-16 Ravi Pratap <ravi@ximian.com>
83 * ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix
86 2002-07-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
88 * expression.cs: fixed bug #27811.
90 2002-07-14 Miguel de Icaza <miguel@ximian.com>
92 * expression.cs (ParameterReference.AddressOf): Patch from Paolo
93 Molaro: when we are a ref, the value already contains a pointer
94 value, do not take the address of it.
96 2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
97 * removed mb-parser.jay and mb-tokenizer.cs
99 Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
101 * expression.cs: check against the building corlib void type.
103 Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
105 * ecore.cs: fix for valuetype static readonly fields: when
106 initializing them, we need their address, not the address of a copy.
108 Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
110 * typemanager.cs: register also enum_type in corlib.
112 Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
114 * class.cs: allow calling this (but not base) initializers in structs.
116 Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
118 * ecore.cs: make sure we compare against the building base types
121 Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
123 * typemanager.cs: fix TypeToCoreType() to handle void and object
124 (corlib gets no more typerefs after this change).
126 2002-07-12 Miguel de Icaza <miguel@ximian.com>
128 * expression.cs (ArrayCreation.EmitArrayArguments): use
129 Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
131 (ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
132 Conv_Ovf_I_Un for the array arguments. Even if C# allows longs as
133 array indexes, the runtime actually forbids them.
135 * ecore.cs (ExpressionToArrayArgument): Move the conversion code
136 for array arguments here.
138 * expression.cs (EmitLoadOpcode): System.Char is a U2, use that
139 instead of the default for ValueTypes.
141 (New.DoEmit): Use IsValueType instead of
142 IsSubclassOf (value_type)
143 (New.DoResolve): ditto.
144 (Invocation.EmitCall): ditto.
146 * assign.cs (Assign): ditto.
148 * statement.cs (Unsafe): Ok, so I got the semantics wrong.
149 Statements *are* currently doing part of their resolution during
152 Expressions do always resolve during resolve, but statements are
153 only required to propagate resolution to their children.
155 2002-07-11 Miguel de Icaza <miguel@ximian.com>
157 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
159 (LoadAssembly): Do not add the dll if it is already specified
161 (MainDriver): Add the System directory to the link path at the end,
162 after all the other -L arguments.
164 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
165 wrong opcode for loading bytes and bools (ldelem.i1 instead of
166 ldelem.u1) and using the opposite for sbytes.
168 This fixes Digger, and we can finally run it.
170 * driver.cs (UnixParseOption): Move the option parsing here.
171 (CSCParseOption): Implement CSC-like parsing of options.
173 We now support both modes of operation, the old Unix way, and the
174 new CSC-like way. This should help those who wanted to make cross
177 The only thing broken is that /r:, /reference: and /lib: are not
178 implemented, because I want to make those have the same semantics
179 as the CSC compiler has, and kill once and for all the confussion
180 around this. Will be doing this tomorrow.
182 * statement.cs (Unsafe.Resolve): The state is checked during
183 resolve, not emit, so we have to set the flags for IsUnsfe here.
185 2002-07-10 Miguel de Icaza <miguel@ximian.com>
187 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
188 not catch the Error_ObjectRefRequired in SimpleName (as it is
189 possible to have a class/instance variable name that later gets
190 deambiguated), we have to check this here.
192 2002-07-10 Ravi Pratap <ravi@ximian.com>
194 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
195 make static and put into Expression.
197 (Event.Define): Register the private field of the event with the
198 TypeManager so that GetFieldFromEvent can get at it.
200 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
201 keep track of the private field associated with an event which
204 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
207 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
209 2002-07-10 Miguel de Icaza <miguel@ximian.com>
211 * expression.cs (Binary.EmitBranchable): this routine emits the
212 Binary expression in a branchable context. This basically means:
213 we need to branch somewhere, not just get the value on the stack.
215 This works together with Statement.EmitBoolExpression.
217 * statement.cs (Statement.EmitBoolExpression): Use
220 2002-07-09 Miguel de Icaza <miguel@ximian.com>
222 * statement.cs (For): Reduce the number of jumps in loops.
224 (For): Implement loop inversion for the For statement.
226 (Break): We can be breaking out of a Try/Catch controlled section
227 (foreach might have an implicit try/catch clause), so we need to
228 use Leave instead of Br.
230 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
231 now). If the instace expression supports IMemoryLocation, we use
232 the AddressOf method from the IMemoryLocation to extract the
233 address instead of emitting the instance.
235 This showed up with `This', as we were emitting the instance
236 always (Emit) instead of the Address of This. Particularly
237 interesting when This is a value type, as we dont want the Emit
238 effect (which was to load the object).
240 2002-07-08 Miguel de Icaza <miguel@ximian.com>
242 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
244 * statement.cs (Checked): Set the CheckedState during the resolve
245 process too, as the ConvCast operations track the checked state on
246 the resolve process, and not emit.
248 * cs-parser.jay (namespace_member_declaration): Flag that we have
249 found a declaration when we do. This is used to flag error 1529
251 * driver.cs: Report ok when we display the help only.
253 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
255 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
257 2002-07-04 Miguel de Icaza <miguel@ximian.com>
259 * cs-tokenizer.cs (define): We also have to track locally the
260 defines. AllDefines is just used for the Conditional Attribute,
261 but we also need the local defines for the current source code.
263 2002-07-03 Miguel de Icaza <miguel@ximian.com>
265 * statement.cs (While, For, Do): These loops can exit through a
266 Break statement, use this information to tell whether the
267 statement is the last piece of code.
269 (Break): Flag that we break.
271 * codegen.cs (EmitContexts): New `Breaks' state variable.
273 2002-07-03 Martin Baulig <martin@gnome.org>
275 * class.cs (TypeContainer.MethodModifiersValid): Allow override
276 modifiers in method declarations in structs. Otherwise, you won't
277 be able to override things like Object.Equals().
279 2002-07-02 Miguel de Icaza <miguel@ximian.com>
281 * class.cs (Method, Property, Indexer): Do not allow the public
282 modifier to be used in explicit interface implementations.
284 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
285 override modifiers in method declarations in structs
287 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
289 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
290 integer or real overflow, report an error
292 2002-07-02 Martin Baulig <martin@gnome.org>
294 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
295 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
296 to tell the runtime about our newly created System.Object and
297 System.ValueType types.
299 2002-07-02 Miguel de Icaza <miguel@ximian.com>
301 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
302 struct instead of Ldarg/Starg.
304 2002-07-02 Martin Baulig <martin@gnome.org>
306 * expression.cs (Indirection.Indirection): Call
307 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
309 2002-07-02 Martin Baulig <martin@gnome.org>
311 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
312 ValueType, call TypeManager.TypeToCoreType() on it.
313 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
314 the OpCodes.Newarr argument.
316 2002-07-02 Martin Baulig <martin@gnome.org>
318 * expression.cs (Invocation.EmitCall): When compiling corlib,
319 replace all calls to the system's System.Array type to calls to
320 the newly created one.
322 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
323 System.Array methods.
324 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
325 from the system's System.Array type which must be replaced.
327 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
329 * typemanager.cs: load unverifiable_code_ctor so we can build
330 corlib using the correct type. Avoid using GetTypeCode() with
332 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
333 TypeManager.object_type to allow building corlib.
335 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
337 * ecore.cs: handle System.Enum separately in LoadFromPtr().
339 2002-07-01 Martin Baulig <martin@gnome.org>
341 * class.cs: Make the last change actually work, we need to check
342 whether `ifaces != null' to avoid a crash.
344 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
346 * class.cs: when we build structs without fields that implement
347 interfaces, we need to add the interfaces separately, since there is
348 no API to both set the size and add the interfaces at type creation
351 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
353 * expression.cs: the dimension arguments to the array constructors
354 need to be converted if they are a long.
356 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
358 * class.cs: don't emit ldarg.0 if there is no parent constructor
359 (fixes showstopper for corlib).
361 2002-06-29 Martin Baulig <martin@gnome.org>
363 MCS now compiles corlib on GNU/Linux :-)
365 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
366 ie. check for MethodImplOptions.InternalCall.
368 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
369 and TypeManager.attribute_type are null, so we must explicitly check
370 whether parent is not null to find out whether it's an attribute type.
371 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
372 and SetBuilder, not only if the property is neither abstract nor external.
373 This is necessary to set the MethodImplOptions on the accessor methods.
374 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
375 SetBuilder, see Property.Emit().
377 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
378 populate "System.Object", "System.ValueType" and "System.Attribute" since
379 they've already been populated from BootCorlib_PopulateCoreTypes().
381 2002-06-29 Martin Baulig <martin@gnome.org>
383 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
384 is the NullLiteral, we also need to make sure that target_type is not
387 2002-06-29 Martin Baulig <martin@gnome.org>
389 * rootcontext.cs (RootContext.ResolveCore): We must initialize
390 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
391 before calling BootstrapCorlib_ResolveDelegate ().
393 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
395 * statement.cs: fixed build-breaker. All tests passed ok.
397 2002-06-27 Martin Baulig <martin@gnome.org>
399 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
400 for System.Decimal when compiling corlib.
402 2002-06-27 Martin Baulig <martin@gnome.org>
404 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
405 switch blocks which contain nothing but a default clause.
407 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
409 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
411 2002-06-27 Martin Baulig <martin@gnome.org>
413 * ecore.cs (PropertyExpr.PropertyExpr): Call
414 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
416 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
417 is already a TypeBuilder.
419 2002-06-27 Martin Baulig <martin@gnome.org>
421 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
422 `target_type == TypeManager.array_type', not IsAssignableFrom() in
423 the "from an array-type to System.Array" case. This makes it work
424 when compiling corlib.
426 2002-06-27 Martin Baulig <martin@gnome.org>
428 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
429 non-static PropertyExpr, set its InstanceExpression. This makes
430 the `ICollection.Count' property work in System/Array.cs.
432 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
434 * driver.cs: Made error handling more consistent. Errors now
435 tracked by Report class, so many methods which used to return int
436 now return void. Main() now prints success/failure and
437 errors/warnings message.
439 Renamed '--probe' compiler argument to '--expect-error'. Removed
440 the magic number return values (123 and 124). Now, if the
441 expected error occurs, the compiler exits with success (exit value
442 0). If the compilation completes without seeing that particular
443 error, the compiler exits with failure (exit value 1). The
444 makefile in mcs/errors has been changed to handle the new behaviour.
446 * report.cs: Made 'expected error' number a property and renamed
447 it from 'Probe' to 'ExpectedError'.
449 * genericparser.cs: Removed error handling support, since it is
450 now all done by Report class.
452 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
453 class, so parse() no longer returns an int.
455 * namespace.cs: Use Report.Error instead of GenericParser.error
457 2002-06-22 Miguel de Icaza <miguel@ximian.com>
459 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
460 TypeContainer.AddOperator): At the front of the list put the
461 explicit implementations, so they get resolved/defined first.
463 2002-06-21 Miguel de Icaza <miguel@ximian.com>
465 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
466 interface type is implemented by this TypeContainer. Used during
467 explicit interface implementation.
469 (Property.Define, Indexer.Define, Method.Define): Validate that
470 the given interface in the explicit implementation is one of the
471 base classes for the containing type.
473 Also if we are explicitly implementing an interface, but there is
474 no match in the pending implementation table, report an error.
476 (Property.Define): Only define the property if we are
477 not explicitly implementing a property from an interface. Use the
478 correct name also for those properties (the same CSC uses,
479 although that is really not needed).
481 (Property.Emit): Do not emit attributes for explicitly implemented
482 properties, as there is no TypeBuilder.
484 (Indexer.Emit): ditto.
486 Hiding then means that we do not really *implement* a pending
487 implementation, which makes code fail.
489 2002-06-22 Martin Baulig <martin@gnome.org>
491 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
492 the return value of Object.GetType(). [FIXME: we need to do this whenever
493 we get a type back from the reflection library].
495 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
497 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
499 2002-06-20 Miguel de Icaza <miguel@ximian.com>
501 * attribute.cs: Return null if we can not look up the type.
503 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
504 the interface types found.
506 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
507 interface types found.
509 * typemanager.cs (GetInterfaces): Make this routine returns alll
510 the interfaces and work around the lame differences between
511 System.Type and System.Reflection.Emit.TypeBuilder in the results
512 result for GetInterfaces.
514 (ExpandInterfaces): Given an array of interface types, expand and
515 eliminate repeated ocurrences of an interface. This expands in
516 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
519 2002-06-21 Martin Baulig <martin@gnome.org>
521 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
524 2002-06-21 Martin Baulig <martin@gnome.org>
526 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
527 and called with one of the core types, return the corresponding typebuilder for
530 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
533 2002-06-21 Martin Baulig <martin@gnome.org>
535 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
536 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
537 (Expression.ConvertReferenceExplicit): Likewise.
539 * expression.cs (ElementAccess.DoResolve): Likewise.
540 (ElementAccess.DoResolveLValue): Likewise.
542 2002-06-10 Martin Baulig <martin@gnome.org>
544 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
545 add the "value" parameter to the parameter list.
547 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
550 2002-06-19 Miguel de Icaza <miguel@ximian.com>
552 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
553 the argument to an int, uint, long or ulong, per the spec. Also
554 catch negative constants in array creation.
556 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
558 * class.cs: do not allow the same interface to appear twice in
561 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
563 * ecore.cs: don't use ldlen with System.Array.
565 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
567 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
569 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
571 * modifiers.cs: produce correct field attributes for protected
572 internal. Easy fix so miguel can work on ther harder stuff:-)
574 2002-06-18 Miguel de Icaza <miguel@ximian.com>
576 * pending.cs: New file. Move the code from class.cs here.
577 Support clearning the pending flag for all methods (when not doing
578 explicit interface implementation).
580 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
582 * rootcontext.cs: added a couple more types needed to bootstrap.
584 2002-06-17 Miguel de Icaza <miguel@ximian.com>
586 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
587 constructor in the type, instead of any constructor in the type
588 hierarchy. Thanks to Paolo for finding this bug (it showed up as
589 a bug in the Mono runtime when applying the params attribute).
591 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
592 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
594 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
596 * expression.cs (Unary.ResolveOperator): Use TypeManager
599 2002-06-13 Ravi Pratap <ravi@ximian.com>
601 * cs-parser.jay (enum_member_declaration): Pass in the attributes
604 * enum.cs (AddEnumMember): Add support to store the attributes associated
605 with each member too.
607 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
608 field builders too - this takes care of the enum member case.
610 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
612 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
613 address-of operator on both value types and pointers.
615 2002-06-10 Martin Baulig <martin@gnome.org>
617 * interface.cs (Interface.PopulateIndexer): Add the indexer's
618 PropertyBuilder to the `property_builders' list.
620 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
621 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
622 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
623 find any indexers which are inherited from an interface.
625 2002-06-09 Martin Baulig <martin@gnome.org>
627 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
628 the same type as the constant if necessary. There's also a test-130.cs
631 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
633 * typemanager.cs (TypeManager.ChangeType): Previously known as
634 Enum.ChangeEnumType().
636 2002-06-09 Martin Baulig <martin@gnome.org>
638 * expression.cs (Cast.TryReduce): Added support for consts.
640 2002-06-08 Ravi Pratap <ravi@ximian.com>
642 * class.cs (Accessor): Hold attributes information so we can pass
645 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
646 Modify to pass in attributes attached to the methods.
648 (add_accessor_declaration, remove_accessor_declaration): Ditto.
650 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
651 to handle the Accessor kind :-)
653 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
655 2002-06-08 Martin Baulig <martin@gnome.org>
657 * expression.cs (Unary.TryReduceNegative): Added support for
660 2002-06-08 Martin Baulig <martin@gnome.org>
662 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
663 name can't be found in the `defined_names' - the caller will do a
664 MemberLookup in this case and thus find methods in System.Enum
665 such as Enum.IsDefined().
667 2002-06-08 Martin Baulig <martin@gnome.org>
669 * enum.cs (Enum.ChangeEnumType): This is a custom version of
670 Convert.ChangeType() which works with TypeBuilder created types.
671 (Enum.LookupEnumValue, Enum.Define): Use it here.
673 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
674 `TypeBuilder.BaseType != null' check.
675 (TypeContainer.FindMembers): Only lookup parent members if we
676 actually have a parent.
677 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
678 (ConstructorInitializer.Resolve): Likewise.
680 * interface.cs (Interface.FindMembers): Added
681 `TypeBuilder.BaseType != null' check.
683 * rootcontext.cs (RootContext.ResolveCore): Added
684 "System.Runtime.CompilerServices.IndexerNameAttribute" to
685 classes_second_stage.
687 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
688 debug_type and trace_type when compiling with --nostdlib.
690 2002-06-07 Martin Baulig <martin@gnome.org>
692 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
693 (AddField): Set it to true when adding a non-static field.
694 (DefineType): Use `have_nonstatic_fields' to find out whether we
695 have non-static fields, not `Fields != null'.
697 2002-06-02 Miguel de Icaza <miguel@ximian.com>
699 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
700 dereferencing a null on the static-field code path)
702 2002-05-30 Martin Baulig <martin@gnome.org>
704 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
705 to take command line arguments. Use reflection to call the new
706 custom `Initialize' function on the symbol writer and pass it the
707 command line arguments.
709 * driver.cs (--debug-args): New command line argument to pass command
710 line arguments to the symbol writer.
712 2002-05-28 Miguel de Icaza <miguel@ximian.com>
714 * assign.cs (DoResolve): Forgot to do the implicit conversion to
715 the target type for indexers and properties. Thanks to Joe for
718 2002-05-27 Miguel de Icaza <miguel@ximian.com>
720 * typemanager.cs (MethodFlags): returns the method flags
721 (Obsolete/ShouldIgnore) that control warning emission and whether
722 the invocation should be made, or ignored.
724 * expression.cs (Invocation.Emit): Remove previous hack, we should
725 not do this on matching a base type, we should do this based on an attribute
727 Only emit calls to System.Diagnostics.Debug and
728 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
731 * rootcontext.cs: Global settings for tracing and debugging.
733 * cs-tokenizer.cs (define): New utility function to track
734 defines. Set the global settings for TRACE and DEBUG if found.
736 2002-05-25 Ravi Pratap <ravi@ximian.com>
738 * interface.cs (Populate*): Pass in the TypeContainer as well as
739 the DeclSpace as parameters so that we can create EmitContexts and
740 then use that to apply attributes etc.
742 (PopulateMethod, PopulateEvent, PopulateProperty)
743 (PopulateIndexer): Apply attributes everywhere.
745 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
748 (ApplyAttributes): Update accordingly.
750 We now apply interface attributes for all members too.
752 2002-05-26 Miguel de Icaza <miguel@ximian.com>
754 * class.cs (Indexer.Define); Correctly check if we are explicit
755 implementation (instead of checking the Name for a ".", we
756 directly look up if the InterfaceType was specified).
758 Delay the creation of the PropertyBuilder.
760 Only create the PropertyBuilder if we are not an explicit
761 interface implementation. This means that explicit interface
762 implementation members do not participate in regular function
763 lookups, and hence fixes another major ambiguity problem in
764 overload resolution (that was the visible effect).
766 (DefineMethod): Return whether we are doing an interface
769 * typemanager.cs: Temporary hack until we get attributes in
770 interfaces (Ravi is working on that) and we get IndexerName
771 support in interfaces.
773 * interface.cs: Register the indexers as properties.
775 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
776 warning, I have verified that this is a bug in the .NET runtime
777 (JavaScript suffers of the same problem).
779 * typemanager.cs (MemberLookup): When looking up members for
780 interfaces, the parent of an interface is the implicit
781 System.Object (so we succeed in searches of Object methods in an
782 interface method invocation. Example: IEnumerable x; x.ToString
785 2002-05-25 Miguel de Icaza <miguel@ximian.com>
787 * class.cs (Event): Events should also register if they do
788 implement the methods that an interface requires.
790 * typemanager.cs (MemberLookup); use the new GetInterfaces
793 (GetInterfaces): The code used to lookup interfaces for a type is
794 used in more than one place, factor it here.
796 * driver.cs: Track the errors at the bottom of the file, we kept
799 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
800 instance if the method we are calling is static!
802 2002-05-24 Miguel de Icaza <miguel@ximian.com>
804 * attribute.cs (ApplyAttributes): Make this function filter out
805 the IndexerName attribute (as that attribute in reality is never
806 applied) and return the string constant for the IndexerName
809 * class.cs (TypeContainer.Emit): Validate that all the indexers
810 have the same IndexerName attribute, and if so, set the
811 DefaultName attribute on the class.
813 * typemanager.cs: The return value might contain other stuff (not
814 only methods). For instance, consider a method with an "Item"
815 property and an Item method.
817 * class.cs: If there is a problem with the parameter types,
820 2002-05-24 Ravi Pratap <ravi@ximian.com>
822 * ecore.cs (ImplicitConversionExists): Wrapper function which also
823 looks at user defined conversion after making a call to
824 StandardConversionExists - we need this for overload resolution.
826 * expression.cs : Update accordingly the various method calls.
828 This fixes 2 bugs filed against implicit user defined conversions
830 2002-05-22 Miguel de Icaza <miguel@ximian.com>
832 * statement.cs: Track the result of the assignment.
834 2002-05-21 Miguel de Icaza <miguel@ximian.com>
836 * expression.cs (MemberAccess): Improved error reporting for
837 inaccessible members.
839 2002-05-22 Martin Baulig <martin@gnome.org>
841 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
842 itself with debugging support.
844 2002-05-22 Martin Baulig <martin@gnome.org>
846 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
847 Removed, this isn't needed anymore.
849 2002-05-20 Martin Baulig <martin@gnome.org>
851 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
852 be underlying type for an enum.
854 2002-05-20 Miguel de Icaza <miguel@ximian.com>
856 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
857 that splits out the loading of just the core types.
859 * rootcontext.cs (ResolveCore): Split the struct resolution in
860 two, so we can load the enumeration underlying types before any
863 * expression.cs (Is): Bandaid until we fix properly Switch (see
864 bug #24985 for details).
866 * typemanager.cs (ImplementsInterface): The hashtable will contain
867 a null if there are no interfaces implemented.
869 2002-05-18 Miguel de Icaza <miguel@ximian.com>
871 * cs-parser.jay (indexer_declarator): It is fine to have array
874 2002-05-17 Miguel de Icaza <miguel@ximian.com>
876 * typemanager.cs: (RegisterBuilder): New function used to register
877 TypeBuilders that implement interfaces. Since
878 TypeBuilder.GetInterfaces (as usual) does not work with lame
880 (AddUserType): register interfaces.
882 (ImplementsInterface): Use the builder_to_ifaces hash if we are
883 dealing with TypeBuilder. Also, arrays are showing up as
884 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
885 methods can not be invoked on them!
887 * ecore.cs (ExplicitReferenceConversionExists): Made public.
888 (ImplicitReferenceConversionExists): Split out from
889 StandardConversionExists.
891 * expression.cs (As): We were only implementing one of the three
892 cases for the as operator. We now implement them all.
893 (Is): Implement the various other cases for Is as well.
895 * typemanager.cs (CACHE): New define used to control if we want or
896 not the FindMembers cache. Seems to have a negative impact on
897 performance currently
899 (MemberLookup): Nested types have full acess to
900 enclosing type members
902 Remove code that coped with instance/static returns for events, we
903 now catch this in RealFindMembers.
905 (RealFindMembers): only perform static lookup if the instance
906 lookup did not return a type or an event.
908 2002-05-17 Miguel de Icaza <miguel@ximian.com>
910 * assign.cs (CompoundAssign): We pass more semantic information
911 now to Compound Assignments than we did before: now we have all
912 the information at hand, and now we resolve the target *before* we
913 do the expression expansion, which allows the "CacheValue" method
914 to have the effect we intended (before, a [x] += 1 would generate
915 two differen ArrayAccess expressions from the ElementAccess,
916 during the resolution process).
918 (CompoundAssign.DoResolve): Resolve target and original_source here.
920 2002-05-16 Miguel de Icaza <miguel@ximian.com>
922 * expression.cs (ArrayAccess): dropped debugging information.
924 * typemanager.cs: Small bug fix: I was always returning i_members,
925 instead of one of i_members or s_members (depending on which had
928 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
929 method is invoked before any code generation takes place, and it
930 is a mechanism to inform that the expression will be invoked more
931 than once, and that the method should use temporary values to
932 avoid having side effects
934 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
936 * ecore.cs (Expression.CacheTemporaries): Provide empty default
939 * expression.cs (Indirection, ArrayAccess): Add support for
940 CacheTemporaries in these two bad boys.
942 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
944 (StoreFromPtr): Handle stobj as well.
946 * expression.cs (UnaryMutator): Share more code.
948 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
949 down: I was not tracking the Filter function as well, which
950 was affecting the results of the cache.
952 2002-05-15 Miguel de Icaza <miguel@ximian.com>
954 * attribute.cs: Remove the hack to handle the CharSet property on
957 2002-05-14 Miguel de Icaza <miguel@ximian.com>
959 * attribute.cs (DoResolve): More uglyness, we now only try to
960 resolve the attribute partially, to extract the CharSet
961 information (only if we are a StructLayout attribute). Otherwise
963 (GetExtraTypeInfo): Add some code to conditionally kill in the
964 future this. I am more and more convinced that the .NET
965 framework has special code to handle the attribute setting on
968 * expression.cs (IsParamsMethodApplicable): Revert my previous
969 foreach change here, it was wrong.
971 2002-05-13 Miguel de Icaza <miguel@ximian.com>
973 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
974 (pp_expr): do not abort on unknown input, just return.
975 (eval): abort if there are pending chars.
977 * attribute.cs (Attribute.Resolve): Positional parameters are
978 optional. Deal with that case.
980 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
981 the Ansi/Unicode/Auto information for the type.
983 (TypeContainer.DefineType): instantiate the EmitContext here, as
984 we will be using it during the type definition (to resolve
985 attributes) and during the emit phase.
987 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
988 to pull type information out of the attributes
990 (Attribute.Resolve): track the constructor builder, and allow for
991 multiple invocations (structs and classes will use this).
993 * ecore.cs (MemberLookupFinal): new version with all the
994 parameters customizable.
996 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
997 constructors. Return if the result value is null (as the error
998 would have been flagged already by MemberLookupFinal)
1000 Do not allow instances of abstract classes or interfaces to be
1003 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
1004 We have to compare the assembly property here when dealing with
1005 FamANDAssem and Assembly access modifiers, because we might be
1006 creating an assembly from *modules* (that means that we are not
1007 getting TypeBuilders for types defined in other modules that are
1008 part of this assembly).
1010 (Method.Emit): If the method is marked abstract and has a body,
1013 (TypeContainer.DefineMembers): If both the defined member and the
1014 parent name match are methods, then do not emit any warnings: let
1015 the Method.Define routine take care of flagging warnings. But if
1016 there is a mismatch (method overrides something else, or method is
1017 overriwritten by something, then emit warning).
1019 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
1020 set to null, this means `do not check for the return type on the
1023 (Method.Define): set the return type for the method signature to
1024 null, so that we get methods with the same name and parameters and
1025 different return types. This is used to flag warning 114 (you are
1026 hiding a method, and you probably want to use the new/override
1029 * typemanager.cs (MemberLookup): Implemented proper access
1030 control, closing a long standing set of bug reports. The problem
1031 was that the Framework only has two bits: Public and NonPublic,
1032 and NonPublic includes private and protected methods, but we need
1033 to enforce the FamANDAssem, FamOrAssem and Family.
1035 2002-05-11 Miguel de Icaza <miguel@ximian.com>
1037 * statement.cs (GotoCase): Return true: Ammounts to giving up
1038 knowledge on whether we return or not, and letting the other case
1039 be responsible for it.
1041 2002-05-10 Miguel de Icaza <miguel@ximian.com>
1043 * driver.cs: Do not load directories for each file processed, only
1044 do it if there is a pattern.
1046 * ecore.cs: Report readonly assigns here as well, as we might have
1047 been resolved only by MemberAccess.
1049 (SimpleName.SimpleNameResolve): Also be useful for LValue
1050 resolution. We need this to propagate assign to local readonly variables
1052 * typemanager.cs: Use a ptrhashtable for the criteria, because we
1053 do not want to reuse potential criteria memory.
1055 * class.cs (MyEventBuilder): Set reflected_type;
1057 * ecore.cs (Constantify): Added support for constifying bools.
1059 (RootContext.LookupType): Added a cache for values looked up in
1060 the declaration space.
1062 * typemanager.cs (FindMembers): Now is a front-end to
1063 RealFindMembers, and provides a two-level hashtable-based cache to
1066 15% performance improvement: from 22.5 to 19.2 seconds.
1068 * expression.cs (IsParamsMethodApplicable): use foreach.
1069 (Invocation.DoResolve): ditto.
1070 (New.DoResolve): ditto.
1071 (ArrayCreation.DoResolve): ditto.
1073 * ecore.cs (FindMostEncompassingType): use foreach.
1075 * delegate.cs (NewDelegate.DoResolve): Use foreach
1077 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
1078 (RemoveMethods): use foreach.
1080 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
1081 nested foreach statements instead of for, and also break out of
1082 the inner loop once a match is found.
1084 (Invocation.OverloadResolve): Use foreach, simplify the code.
1086 2002-05-08 Miguel de Icaza <miguel@ximian.com>
1088 * cfold.cs (BinaryFold): During an enumeration evaluation context,
1089 we actually unwrap the expression to allow for extra information
1092 * expression.cs: Use Shr_Un on unsigned operations.
1094 2002-05-08 Ravi Pratap <ravi@ximian.com>
1096 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
1097 applicable operators was not being considered correctly. This closes
1098 the bug Miguel reported.
1100 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
1102 * attribute.cs: check that the type derives from System.Attribute
1103 and report the correct error in that case (moved the duplicate code to
1104 its own method, too).
1106 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
1108 * attribute.cs: lookup attribute type name as the spec says: first the
1109 bare attribute name and then name + "Attribute" (nant compiles with
1110 mcs after this fix).
1112 2002-05-07 Miguel de Icaza <miguel@ximian.com>
1114 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
1115 Because of the way we parse things, we should try to see if a
1116 UIntConstant can fit in an integer.
1118 2002-05-07 Ravi Pratap <ravi@ximian.com>
1120 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
1121 when we are in an explicit context.
1123 (ConvertReferenceExplicit): When converting from Iface type S to Class
1124 T make sure the rules are implemented as an OR.
1126 * parameter.cs (ParameterType): Make it a property for now although the
1127 purpose really isn't anything immediate.
1129 * expression.cs (Is*Applicable): Do better checking on the parameter type
1130 of a ref/out parameter. The ones from the system assemblies are already
1131 marked with the correct type so we don't need to do any correction.
1133 * ecore.cs (StandardConversionExists): Conversion from Interface types to
1134 the object type is standard too so include that.
1136 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1138 * ecore.cs (StandardConversionExists): Augment with missing code:
1139 deal with IntConstant, LongConstants and Enumerations.
1141 * assign.cs: Report the error, instead of failing silently
1143 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
1144 typecontainer that they are declared, because the
1145 typecontainer/namespace will have the list of using clauses that
1148 Assembly Attributes were escaping the normal registration
1151 (EmitCode): Apply attributes within an EmitContext that represents
1152 the container they were declared on.
1154 * cs-parser.jay: Track bases for structs. How did I get this wrong?
1156 2002-05-06 Ravi Pratap <ravi@ximian.com>
1158 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
1159 Revamp completely - make much cleaner as we now operate only
1162 (FindMostSpecificSource, FindMostSpecificTarget): New methods
1163 to implement the logic detailed in the spec more correctly.
1165 (UserDefinedConversion): Update accordingly.
1167 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1169 * statement.cs: Return flow analysis information up.
1171 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
1174 (token): Do not consume an extra character before calling
1177 2002-05-06 Piers Haken <piersh@friskit.com>
1179 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
1181 2002-05-06 Miguel de Icaza <miguel@ximian.com>
1183 * class.cs (Constructor.Emit): Set the IsStatic flag in the
1184 EmitContext during the instance constructor initializer
1185 resolution, to stop access to instance variables.
1187 This is mandated by the spec, last paragraph of the `constructor
1188 initializers' section.
1190 2002-05-05 Miguel de Icaza <miguel@ximian.com>
1192 * cs-parser.jay, class.cs (Accessor): new class used to represent
1193 an accessor (get or set). In the past we used `null' to represent
1194 a missing accessor. But this is ambiguous because there was no
1195 way to tell in abstract indexers/properties if one of them was
1198 Now there is a way of addressing that.
1200 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
1201 instead of FindMembers.
1203 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
1204 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
1206 * attribute.cs: Treat indexers and properties as the same in terms
1207 of applying attributes
1209 * ecore.cs (FindMostEncompassedType): Use statically initialized
1210 EmptyExpressions()s like we do elsewhere to avoid creating useless
1211 objects (and we take this out of the tight loop).
1213 (GetConversionOperators): Move the code to extract the actual
1214 operators to a separate routine to clean things up.
1216 2002-05-04 Miguel de Icaza <miguel@ximian.com>
1218 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
1219 events are always registered FieldBuilders.
1221 * class.cs (FieldBase): New class shared by Fields
1223 * delegate.cs: If we are a toplevel delegate, use our full name.
1224 If we are a nested delegate, then only use our tail name.
1226 2002-05-02 Ravi Pratap <ravi@ximian.com>
1228 * expression.cs (IsApplicable): Ensure that we add the "&" to
1229 ref/out types before comparing it with the type of the argument.
1231 (IsParamsMethodApplicable): Ditto.
1233 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
1236 * delegate.cs : Handle the case when we have more than one applicable
1237 method. Flag an error only when we finish checking all.
1239 2002-05-02 Miguel de Icaza <miguel@ximian.com>
1241 * expression.cs: Add support for boolean static initializers.
1243 2002-05-01 Miguel de Icaza <miguel@ximian.com>
1245 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
1247 * parameter.cs (ComputeParameterTypes,
1248 ComputeAndDefineParameterTypes): Better error handling: now we
1249 clear the `types' cache if we fail during any of the type lookups.
1250 We also return the status code correctly to our caller
1252 * delegate.cs: If we fail to define a delegate, abort the extra
1255 * expression.cs (Binary.ResolveOperator): for
1256 operator==(object,object) and operator !=(object, object) we also
1257 have to verify that there is an implicit conversion from one to
1260 (ArrayAccess.DoResolve): Array Access can operate on
1263 2002-04-30 Miguel de Icaza <miguel@ximian.com>
1265 * assign.cs (CompoundAssign): A new class used as a "flag" that
1266 the assignment actually is happening as part of a compound
1267 assignment operator.
1269 During compound assignment, a few new rules exist to enable things
1276 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
1277 to the type of x) if y is implicitly convertible to the type of x,
1278 and the operator is a builtin operator and the return type of the
1279 operator is explicitly convertible to the type of x.
1281 * rootcontext.cs: Reset warning level to 2. 4 catches various
1282 "interesting" features in mcs, we must clean this up at some
1283 point, but currently am trying to kill other bugs ;-)
1285 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
1286 in container classes as well.
1288 * expression.cs (Binary.ResolveOperator): Handle string case
1289 before anything else (as operator overloading does emit an error
1290 before doing anything else).
1292 This code could go away when we move to a table driven model, but
1293 i could not come up with a good plan last night.
1295 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
1297 * typemanager.cs (CSharpName): reimplementation using regex.
1298 * class.cs: added null check for fields in Emit
1299 * rootcontext.cs: set warninglevel to 4
1301 2002-04-29 Miguel de Icaza <miguel@ximian.com>
1303 * typemanager.cs (CSharpName): reimplemented with Lupus
1306 2002-04-28 Miguel de Icaza <miguel@ximian.com>
1308 * statement.cs (If): correclty implement Resolve, because we were
1309 not catching sem errors in there. The same process is needed
1311 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
1314 (Statement.Warning_DeadCodeFound): Factorize code.
1315 (While): Report dead code here too.
1317 (Statement): Added Resolve virtual method to allow
1318 for resolution split from the emit code.
1320 2002-04-26 Miguel de Icaza <miguel@ximian.com>
1322 * statement.cs (EmitBoolExpression): No longer try to resolve the
1324 (MakeBoolean): New utility function that resolve, implicitly
1325 converts to boolean and tags the expression.
1328 (If, Do): Implement dead code elimination.
1329 (While): Implement loop inversion
1331 (Do, While, For, If): Resolve the expression prior to calling our
1334 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
1337 - added method Report28 (warning: program has more than one entry point)
1338 - added method IsEntryPoint, implements paragraph 10.1 of the spec
1339 - modified method Method.Define, the part at the end of the method
1341 * rootcontext.cs: added static public Location EntryPointLocation;
1343 * ../errors/cs0028.cs : Add test case for the above warning.
1346 - modified method CSharpName to allow arrays of primitive type to
1347 be printed nicely (e.g. instead of System.Int32[][] it now prints
1349 - added method CSharpSignature: returns the signature of a method
1350 in string format to be used in reporting errors, warnings, etc.
1352 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
1355 2002-04-26 Ravi Pratap <ravi@ximian.com>
1357 * delegate.cs (Define): Fix extremely silly bug where I was
1358 setting the type of the 'object' parameter of the BeginInvoke
1359 method to System.IAsyncResult instead of System.Object ;-)
1361 2002-04-26 Miguel de Icaza <miguel@ximian.com>
1363 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
1366 (Constructor.Emit): return if we fail to initialize the
1367 constructor. Another door closed!
1369 * expression.cs (New.DoResolve): Improve error message (from -6 to
1370 1501). Use DeclaredOnly lookup to find the exact constructor.
1372 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
1373 loop. This is useful.
1375 * cs-parser.jay: Adjust the default parameters so that destructors
1376 have the proper signature.
1378 2002-04-26 Martin Baulig <martin@gnome.org>
1380 * driver.cs (LoadAssembly): If `assembly' contains any characters
1381 which are only valid in path names and not in assembly names
1382 (currently slash, backslash and point), use Assembly.LoadFrom ()
1383 instead of Assembly.Load () on the `assembly' (before iteration
1384 over the link_paths).
1386 2002-04-26 Martin Baulig <martin@gnome.org>
1388 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
1390 2002-04-25 Miguel de Icaza <miguel@ximian.com>
1392 * class.cs (Property): use the new typemanager.MemberLookup
1394 (TypeContainer.MemberLookup): Implement using the
1395 TypeManager.MemberLookup now.
1397 * typemanager.cs: Make MemberLookup a function of the TypeManager,
1398 and return MemberInfos, so that these can be used without an
1399 EmitContext (what we had before).
1401 2002-04-24 Miguel de Icaza <miguel@ximian.com>
1403 * expression.cs: Fix the case where the argument to params if the
1404 type of the params. I omitted handling this before. Fixed
1406 2002-04-22 Miguel de Icaza <miguel@ximian.com>
1408 * driver.cs: Call BootCorlib_PopulateCoreType
1410 * class.cs (Property.CheckBase): Check for properties only, not
1413 * interface.cs: Temporary hack: try/catch around the
1414 CustomAttributeBuilder, because I am getting an exception that I
1417 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
1418 types whose definitions are required to be there (attributes are
1419 defined before standard types).
1421 Compute definitions as we boot the various types, as they are used
1422 immediately (value_type class will need object_type, but if we do
1423 not initialize object_type, we will pass a null, which will let
1424 the runtime pick the System.Object from the existing corlib, which
1425 is not what we want).
1427 2002-04-22 Patrik Torstensson <totte@labs2.com>
1429 * cs-tokenizer.cs: fixed a number of trim() issues.
1431 2002-04-22 Ravi Pratap <ravi@ximian.com>
1433 * expression.cs (Argument.Type): Ensure that we return the correct
1434 type when we have out or ref parameters [in which case we
1437 2002-04-22 Miguel de Icaza <miguel@ximian.com>
1439 * class.cs (Property, Indexer): Allow extern modifier in there.
1441 * typemanager.cs (InitBaseTypes): Initializes object_type and
1442 value_type, since those will be used early on during the bootstrap
1443 process to compile corlib.
1445 (InitCoreTypes): Move code from here to InitBaseTypes.
1447 2002-04-21 Miguel de Icaza <miguel@ximian.com>
1449 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
1450 single-dimension arrays as using the ldlen opcode.
1452 Daniel Lewis discovered this optimization.
1454 * typemanager.cs: Add signature for System.Array::get_Length
1456 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1458 * statement.cs: report the error when the foreach does not apply to an
1459 array nor a collection.
1461 2002-04-19 Miguel de Icaza <miguel@ximian.com>
1463 * expression.cs: Add implicit conversions to the operator ~.
1465 * constant.cs (DecimalConstant.Emit): Emit decimal value.
1467 * typemanager.cs: Locate the decimal constructor.
1469 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1471 * attribute.cs: use the new property of TypeOf.
1472 * expression.cs: added 'get' property around typearg.
1474 These changes fix a build breaker reported by NickD. Is this the
1475 correct way to fix? If not, please, revert my changes and make it
1478 2002-04-17 Miguel de Icaza <miguel@ximian.com>
1480 * attribute.cs: Add support for typeof in attribute invocations.
1481 I am not sure that this is right though.
1483 2002-04-14 Duncan Mak <duncan@ximian.com>
1485 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
1486 Binary.Operator.Division case.
1488 2002-04-13 Ravi Pratap <ravi@ximian.com>
1490 * class.cs (DefineType): Ensure that we do a proper check on
1491 attribute types and also register it with the TypeManager.
1493 (TypeContainer.Targets): The default for attribute types is
1494 AttributeTargets.All.
1496 * attribute.cs (ApplyAttributes): Registering the attribute type
1497 is done elsewhere, not when we discover we have a Usage attribute.
1499 2002-04-12 Ravi Pratap <ravi@ximian.com>
1501 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
1502 and get rid of is_delegate parameter.
1504 * everywhere : update.
1506 2002-04-12 Ravi Pratap <ravi@ximian.com>
1508 * cs-parser.jay (compilation_unit): Revamp completely to use
1509 some new ideas that I got from Rhys' grammar to solve the problems
1510 with assembly level attributes.
1512 (outer_declaration): New grammar production.
1514 (attribute_sections): Add.
1516 (opt_attributes): Base on attribute_sections
1518 (namespace_declaration): Allow opt_attributes to tackle the case
1519 when we have assembly level attributes - we are clever in this
1522 * attribute.cs (ApplyAttributes): Do not worry about assembly
1523 attributes in the non-global context.
1525 * rootcontext.cs (AddGlobalAttributes): Go back to using this
1526 instead of SetGlobalAttributes.
1528 * class.cs, rootcontext.cs : Ensure we define and generate
1529 attribute types before anything else.
1531 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
1532 and flag the new error -20 for the case when the attribute type
1533 does not have valid targets specified. csc does not catch this.
1535 * ../errors/errors.txt : update for error # -20
1537 2002-04-11 Ravi Pratap <ravi@ximian.com>
1539 * support.cs (InternalParameters.ParameterModifier): Do some null
1540 checking and return sane values.
1542 * class.cs (Method.Define): If we are a PInvoke method, ensure
1543 that we are static and extern. Report error # 601
1545 * ../errors/cs0601.cs : Add test case for the above error.
1547 2002-04-07 Ravi Pratap <ravi@ximian.com>
1549 * rootcontext.cs (attribute_types): We need to keep type of
1550 all attribute types separately and emit code for them first.
1552 (RegisterAttribute) : Implement.
1554 * class.cs (DefineType): Check if the current Type is a custom
1555 attribute type and register it accordingly.
1557 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
1558 adding the first attribute twice and rename to
1560 (SetGlobalAttributes): this.
1562 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
1565 * attribute.cs (ApplyAttributes): Take an additional argument telling us
1566 if we are processing global arguments. Hmm, I am unsure of this.
1568 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1570 * expression.cs: added static array of strings to avoid calling
1571 Enum.ToString () for Operator in Binary. Significant recover of
1574 2002-04-10 Miguel de Icaza <miguel@ximian.com>
1576 * class.cs (FindMembers): Allow the Builders of the various
1577 members to be null. If they are skip them. This only happens
1578 during the PInvoke declaration.
1580 2002-04-09 Miguel de Icaza <miguel@ximian.com>
1582 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
1583 failure, so we do not keep going afterwards.
1585 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
1586 wanted to pass `false' as the `is_delegate' argument. If this is
1587 the case, why not use delegate_type == null to mean `is_delegate =
1588 false' and anything else as is_delegate = true.
1590 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
1592 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
1593 code for the section, not the beginning of the tests.
1595 2002-04-08 Miguel de Icaza <miguel@ximian.com>
1597 * cfold.cs: Handle operator + (Enum x, Underlying x)
1599 * expression.cs (Binary): same. Warn about errors where we have
1600 Enum/Enum in operator + as well.
1602 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
1605 - added support for switch(bool)
1606 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
1607 - add TableSwitchEmit() to handle table-based switch statements
1609 2002-04-05 Ravi Pratap <ravi@ximian.com>
1611 * expression.cs (Invocation.OverloadResolve): Factor out code which
1612 does parameter compatibility checking with arguments so that we can
1613 re-use the code even from Delegate.VerifyApplicability
1615 (VerifyArgumentsCompat): Move above code here.
1617 * delegate.cs (VerifyApplicability): Get rid of duplicate code
1618 and instead make a call to the above method.
1620 2002-03-31 Ravi Pratap <ravi@ximian.com>
1622 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
1623 We use it to keep track of classes which are attribute types.
1625 2002-04-02 Miguel de Icaza <miguel@ximian.com>
1627 * delegate.cs (Delegate.Define): Correctly define the types in the
1628 presence of fixed and array parameters.
1630 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
1633 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
1634 include NonPublic after the first iteration.
1636 * class.cs (Indexer.CheckBase): Only check if both parents are
1639 * cs-parser.jay (accessor_body): If empty, set to null.
1641 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
1642 same code path here to resolve constants names that we did have in
1643 MemberAccess.DoResolve. There is too much code duplicated here.
1645 2002-04-01 Miguel de Icaza <miguel@ximian.com>
1647 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
1649 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
1652 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
1653 tokens, numbers and strings.
1655 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
1658 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
1659 asyncronous parameters and the regular parameters.
1661 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
1662 specify the target directory.
1664 * expression.cs: (This.DoResolve): Simplify
1665 (As.Emit): Optimize, do not generate IsInst if the expression is
1666 always of the given type.
1668 (Is.DoResolve): Bug fix, we were reporting both always/never for
1671 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
1672 creating too many unnecessary arrays.
1674 2002-03-31 Miguel de Icaza <miguel@ximian.com>
1676 * class.cs (EmitFieldInitializer): Use Assign expression to assign
1677 fields instead of rolling our own initializer. Takes care of all
1678 implicit conversions, and drops unnecessary static checks/argument.
1680 2002-03-31 Dick Porter <dick@ximian.com>
1682 * driver.cs: use the GetDirectories() return values properly, and
1683 use "/" as path separator.
1685 2002-03-30 Miguel de Icaza <miguel@ximian.com>
1687 * expression.cs (Unary): Optimize - - expr into expr.
1688 (Binary): Optimize a + (-b) into a -b.
1690 * codegen.cs (CodeGen): Made all methods static.
1692 2002-03-29 Miguel de Icaza <miguel@ximian.com>
1696 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
1697 TypeBuilder property.
1699 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
1702 * tree.cs: Removed the various RecordXXXX, and replaced with a
1703 single RecordDecl. Removed all the accessor methods, and just
1704 left a single access point Type
1706 * enum.cs: Rename DefineEnum to DefineType.
1708 * decl.cs: New abstract method `DefineType' used to unify the
1709 Defines for Enumerations, Interfaces, TypeContainers and
1712 (FindType): Moved LookupInterfaceOrClass here. Moved the
1713 LookupBaseClasses method that used to live in class.cs and
1714 interface.cs here, and renamed to FindType.
1716 * delegate.cs: Implement DefineType. Take advantage of the
1717 refactored pattern for locating the parent builder without taking
1718 the parent_builder argument (which we know does not work if we are
1719 nested, and triggering a toplevel definition).
1721 2002-03-28 Miguel de Icaza <miguel@ximian.com>
1723 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
1724 accessibility of a member has changed during override and report
1727 * class.cs (Method.Define, Property.Define): Only complain on
1728 overrides if the method is private, any other accessibility is
1729 fine (and since we just checked the permission is the same, we are
1732 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
1733 and elif are processed always. The other pre-processing
1734 directives are only processed if we are "taking" the path
1736 2002-03-29 Martin Baulig <martin@gnome.org>
1738 * class.cs (Method.Emit): Only emit symbolic debugging info if the
1739 current location is not Null.
1741 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
1742 a separate method so we can profile it.
1744 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
1745 `span.Seconds' are just seconds, but no minutes or hours.
1746 (MainDriver): Profile the CodeGen.SaveSymbols calls.
1748 2002-03-28 Miguel de Icaza <miguel@ximian.com>
1750 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
1751 Remove the gratuitous set of Final:
1753 // If an interface implementation, then we can set Final.
1754 if (((flags & MethodAttributes.Abstract) == 0) &&
1755 implementing.DeclaringType.IsInterface)
1756 flags |= MethodAttributes.Final;
1758 I do not know what I was smoking when I used that.
1761 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
1762 step into fixing the name resolution issues for delegates and
1763 unifying the toplevel name resolution.
1765 2002-03-28 Martin Baulig <martin@gnome.org>
1767 * class.cs (Method.Emit): If we have a symbol writer, call its
1768 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
1769 tell it about the current method.
1771 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
1772 writer that we're going to emit the first byte of IL code for a new
1773 statement (a new source line).
1774 (EmitContext.EmitTopBlock): If we have a symbol writer, call
1775 EmitContext.Mark() before emitting any code.
1777 * location.cs (SymbolDocument): Return null when we're Null.
1779 * statement.cs (Statement): Moved the `Location loc' variable here.
1780 (Statement.EmitBoolExpression): If we have a symbol writer, call
1781 ec.Mark() before emitting any code to tell it that we're at the
1782 beginning of a new statement.
1783 (StatementExpression): Added `Location' argument to the constructor.
1784 (Block): Added public readonly variable `StartLocation' and public
1785 variable `EndLocation'. The latter is to be set using SetEndLocation().
1786 (Block): Added constructor which takes a start and end location.
1787 (Block.SetEndLocation): New method. This sets the end location.
1788 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
1789 local variables we create.
1790 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
1791 each statement and do also mark the begin and end of the block.
1793 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
1794 tell it the current lexer.Location, use Location.Null for the end of the
1796 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
1797 current block, set its end location using SetEndLocation().
1798 (statement_expression): StatementExpression constructor now takes the
1799 lexer.Location as additional argument.
1800 (for_statement, declare_local_variables): Likewise.
1801 (declare_local_variables): When creating a new implicit block, use the
1802 new Block constructor and pass it the lexer.Location.
1804 2002-03-28 Miguel de Icaza <miguel@ximian.com>
1806 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
1807 members also on the parent interfaces recursively.
1809 2002-03-27 Miguel de Icaza <miguel@ximian.com>
1811 * report.cs: Use new formats, since Gonzalo finished the missing
1814 * expression.cs (Binary.ResolveOperator): added missing operator|
1815 operator& and operator^ for bool/bool.
1817 * cs-parser.jay: CheckDef now takes a Location argument that is
1818 used to report errors more precisly (instead of reporting the end
1819 of a definition, we try to track something which is a lot closer
1820 to the source of the problem).
1822 * cs-tokenizer.cs: Track global token use, so we can properly flag
1823 the use of #define/#undef after the first token has been seen.
1825 Also, rename the reportXXXX to Error_DescriptiveName
1827 * decl.cs (DeclSpace.IsTopLevel): Move property here from
1828 TypeContainer, so that Enum and Interface can use this too.
1830 * class.cs (TypeContainer.LookupInterfaceOrClass,
1831 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
1832 `builder' argument. Typically this was used to pass the parent
1833 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
1836 The problem is that a nested class could trigger the definition of
1837 a toplevel class, and the builder would be obviously wrong in that
1840 So we drop this argument, and we compute dynamically the
1841 TypeBuilder/ModuleBuilder (the correct information was available
1842 to us anyways from DeclSpace.Parent)
1844 * interface.cs (Interface.DefineInterface): Drop builder
1845 parameter cleanup like class.cs
1847 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
1850 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
1853 (Try.Emit): Propagate the returns value from the statement.
1855 (Return.Emit): Even if we are leavning
1857 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
1859 * modifiers.cs: Fix the computation of MethodAttributes flags.
1861 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
1863 * driver.cs: allow compilation of files that start with '/'.
1864 Add a default case when checking the argument of --target.
1866 2002-03-25 Miguel de Icaza <miguel@ximian.com>
1868 * interface.cs: Implement the same search algorithm for types in
1871 * delegate.cs: Do not allow multiple definition.
1873 * Recovered ChangeLog that got accidentally amputated
1875 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
1877 * rootcontext.cs: Load manually enum to allow core classes to
1878 contain enumerations.
1880 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
1881 Update to new static methods in TypeManager.
1883 * typemanager.cs (GetMethod, GetConstructor): Use our
1884 implementation of FindMembers to find the members, since during
1885 corlib compilation, the types are TypeBuilders and GetMethod and
1886 GetConstructor do not work.
1888 Make all methods in TypeManager static.
1890 (InitCodeHelpers): Split the functionality from
1891 the InitCodeTypes function.
1893 * driver.cs: Call InitCodeHelpers after we have populated the
1896 * cs-parser.jay (delegate_declaration): we did not used to compute
1897 the delegate name correctly for void delegates.
1899 2002-03-24 Miguel de Icaza <miguel@ximian.com>
1901 * rootcontext.cs (RootContext): Init the interface_resolve_order
1902 and type_container_resolve_order always.
1904 (ResolveCore, BootstrapCorlib_ResolveClass,
1905 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
1906 compiler when compiling with --nostdlib
1908 * class.cs (TypeContainer.DefineType): Check that our parent is
1909 not null. This test is most important when we are bootstraping
1912 * codegen.cs: Split out the symbol writing code.
1914 2002-03-25 Martin Baulig <martin@gnome.org>
1916 * driver.cs (-g): Made -g an alias for --debug.
1918 2002-03-24 Martin Baulig <martin@gnome.org>
1920 * codegen.cs (SymbolWriter): New public variable. Returns the
1921 current symbol writer.
1922 (CodeGen): Added `bool want_debugging_support' argument to the
1923 constructor. If true, tell the ModuleBuild that we want debugging
1924 support and ask it for the ISymbolWriter.
1925 (Save): If we have a symbol writer, call it's Close() method after
1926 saving the assembly.
1928 * driver.c (--debug): New command line argument to create a
1929 debugger information file.
1931 * location.cs (SymbolDocument): New public property. Returns an
1932 ISymbolDocumentWriter object for the current source file or null
1933 if we don't have a symbol writer.
1935 2002-03-21 Miguel de Icaza <miguel@ximian.com>
1937 * driver.cs (LoadAssembly): Correctly return when all the paths
1938 have been tried and not before.
1940 * statement.cs (Switch.Emit): return the actual coverage for this
1941 statement (returns/not-returns)
1943 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
1944 switch of the statement if we are the last switch section. That
1945 kills two problems: try/catch problems (we used to emit an empty
1946 nop at the end) and switch statements where all branches would
1949 2002-03-19 Miguel de Icaza <miguel@ximian.com>
1951 * driver.cs: Add default assemblies (the equivalent to the
1952 Microsoft CSC.RSP file)
1954 * cs-tokenizer.cs: When updating `cols and setting it to zero,
1955 also update tokens_seen and set it to false.
1957 * driver.cs: Implement --recurse for Mike.
1959 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
1960 correctly splitting out the paths.
1962 2002-03-18 Miguel de Icaza <miguel@ximian.com>
1964 * interface.cs (Interface.PopulateProperty): Instead of using
1965 `parent' as the declaration space for the set parameters, use
1968 * support.cs (InternalParameters): InternalParameters constructor
1969 takes a DeclSpace instead of a TypeContainer.
1971 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
1972 types are being initialized, load the address of it before calling
1975 (New): Provide a mechanism to disable the generation of local
1976 value type temporaries when the caller will be providing us with
1977 an address to store it.
1979 (ArrayCreation.EmitDynamicInitializers): Use it.
1981 2002-03-17 Miguel de Icaza <miguel@ximian.com>
1983 * expression.cs (Invocation.EmitArguments): Only probe for array
1984 property if there is more than one argument. Sorry about that.
1986 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
1989 * class.cs (Method.LabelParameters): Fix incorrect code path that
1990 prevented the `ParamArrayAttribute' from being applied to the
1993 2002-03-16 Miguel de Icaza <miguel@ximian.com>
1995 * support.cs (ReflectionParameters): Correctly compute whether the
1996 last argument is a params array. Fixes the problem with
1999 * typemanager.cs: Make the assemblies array always be non-null
2000 (empty, but non-null)
2002 * tree.cs (RecordDecl): New function that abstracts the recording
2003 of names. This reports error 101, and provides a pointer to the
2004 previous declaration. Fixes a crash in the compiler.
2006 * cs-parser.jay (constructor_declaration): Update to new grammar,
2007 and provide a constructor_body that can be empty.
2009 2002-03-15 Miguel de Icaza <miguel@ximian.com>
2011 * driver.cs: Add support for --resources.
2013 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
2014 Make all types for the various array helper methods be integer.
2016 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
2017 CheckState to ConvCast.
2019 (ConvCast): Now it takes a `checked' state argument, to avoid
2020 depending on the emit context for the conversion, and just using
2021 the resolve time setting.
2023 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
2024 instead of Invocation.EmitArguments. We do not emit the original
2025 arguments, instead we emit those which have been converted to
2026 unsigned int expressions.
2028 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
2030 * codegen.cs: ditto.
2032 * expression.cs (LocalVariableReference): Drop the use of the
2033 Store function that depended on the variable index.
2035 * statement.cs (VariableInfo): Drop the `Idx' property from this
2036 class, as this is not taking into account the indexes for
2037 temporaries tat we generate during the execution, getting the
2040 * class.cs: First emit class initializers, then call the parent
2043 * expression.cs (Binary): Fix opcode emision.
2044 (UnaryMutator.EmitCode): Support checked code generation
2046 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
2047 matches for events for both the Static and Instance scans,
2048 pointing to the same element. Fix that.
2050 2002-03-14 Miguel de Icaza <miguel@ximian.com>
2052 * rootcontext.cs (ResolveTree): Always set the
2053 interface_resolve_order, because nested interfaces will be calling
2056 * class.cs (GetInterfaceOrClass): Track the same resolution
2057 process used by TypeManager.LookupType. This fixes the nested
2058 type lookups in class declarations (separate path from
2061 (TypeContainer.DefineType): Also define nested interfaces.
2062 (TypeContainer.RegisterOrder): New public function used to
2063 register the order in which child interfaces need to be closed.
2065 Nested interfaces need to be closed after their parents have been
2068 * interface.cs (InterfaceAttr): Put all the logic for computing
2069 the interface attribute here.
2071 (DefineInterface): Register our interface order with the
2072 RootContext or with the TypeContainer depending on the case.
2074 2002-03-12 Miguel de Icaza <miguel@ximian.com>
2076 * cs-parser.jay: rework foreach statement to work with the new
2077 changes to the policy on SimpleNames.
2079 * report.cs: support Stacktrace on warnings as well.
2081 * makefile: drop --unsafe and /unsafe from the compile.
2083 2002-03-13 Ravi Pratap <ravi@ximian.com>
2085 * ecore.cs (StandardConversionExists): Modify to take an Expression
2086 as the first parameter. Ensure we do null -> reference type conversion
2089 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
2090 temporary Expression objects.
2092 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
2094 * interface.cs: workaround bug in method overloading resolution
2095 (there is already a bugzilla bug for it).
2097 2002-03-12 Miguel de Icaza <miguel@ximian.com>
2099 We could also solve this problem by having a separate path for
2100 performing type lookups, instead of DoResolve, we could have a
2101 ResolveType entry point, and only participating pieces of the
2102 production (simplename, deref, array) would implement this.
2104 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
2105 signal SimpleName to only resolve type names and not attempt to
2106 resolve anything else.
2108 * expression.cs (Cast): Set the flag.
2110 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
2112 * class.cs: Only report 108 if there is no `new' modifier.
2114 * cs-parser.jay: rework foreach statement to work with the new
2115 changes to the policy on SimpleNames.
2117 * report.cs: support Stacktrace on warnings as well.
2119 * makefile: drop --unsafe and /unsafe from the compile.
2121 2002-03-11 Miguel de Icaza <miguel@ximian.com>
2123 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
2124 lookups here, instead of doing that at parse time. This means
2125 that our grammar will not introduce `LocalVariableReferences' as
2126 expressions at this point. That solves the problem of code like
2134 This is only half the fix. The full fix requires parameters to
2135 also be handled in this way.
2137 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
2138 makes the use more obvious of the DeclSpace. The
2139 ec.TypeContainer.TypeBuilder is now only used to pull the
2142 My theory is that I can get rid of the TypeBuilder completely from
2143 the EmitContext, and have typecasts where it is used (from
2144 DeclSpace to where it matters).
2146 The only pending problem is that the code that implements Aliases
2147 is on TypeContainer, and probably should go in DeclSpace.
2149 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
2150 lookups here, instead of doing that at parse time. This means
2151 that our grammar will not introduce `LocalVariableReferences' as
2152 expressions at this point. That solves the problem of code like
2160 This is only half the fix. The full fix requires parameters to
2161 also be handled in this way.
2163 * class.cs (Property.DefineMethod): When implementing an interface
2164 method, set newslot, when implementing an abstract method, do not
2165 set the flag (before we tried never setting it, or always setting
2166 it, which is the difference).
2167 (Indexer.DefineMethod): same.
2168 (Method.DefineMethod): same.
2170 * ecore.cs: Only set the status used flag if we get back a Field.
2172 * attribute.cs: Temporary hack, so Paolo can keep working.
2174 2002-03-08 Ravi Pratap <ravi@ximian.com>
2176 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
2177 the unmanaged type in the case we have a MarshalAs attribute.
2179 (Resolve): Handle the case when we are parsing the special MarshalAs
2180 attribute [we need to store the unmanaged type to use later]
2182 * typemanager.cs (marshal_as_attr_type): Built in type for the
2183 MarshalAs Attribute.
2185 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
2186 on parameters and accordingly set the marshalling info.
2188 2002-03-09 Miguel de Icaza <miguel@ximian.com>
2190 * class.cs: Optimizing slightly by removing redundant code after
2191 we switched to the `NoTypes' return value.
2192 (Property.DefineMethod): use NoTypes here too.
2194 This fixes the bug I introduced in my last batch of changes.
2196 2002-03-05 Ravi Pratap <ravi@ximian.com>
2198 * tree.cs (RecordEnum): Add. We now keep track of enums too.
2200 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
2201 Enums since those are types too.
2203 * cs-parser.jay (enum_declaration): Record enums as we parse them.
2205 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
2206 thanks to a call during the lookup process.
2208 2002-03-07 Miguel de Icaza <miguel@ximian.com>
2210 * statement.cs (Foreach): Lots of work to accomodate a particular
2211 kind of foreach statement that I had not kept in mind. It is
2212 possible to have foreachs on classes that provide a GetEnumerator
2213 method that return objects that implement the "pattern" for using
2214 a foreach, there is no need to support GetEnumerator
2217 This is needed to compile nant.
2219 * decl.cs: Only report 114 if the member is not `Finalize' and if
2220 the warning level is at least 2.
2222 * class.cs: Moved the compare function from Method to
2225 (MethodSignature.InheritableMemberSignatureCompare): Add new
2226 filter function that is used to extract inheritable methods from a
2229 (Method.Define): Use the new `inheritable_method_signature_filter'
2232 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
2235 2002-03-06 Miguel de Icaza <miguel@ximian.com>
2237 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
2239 * cs-parser.jay: Add opt_semicolon to the interface declaration.
2241 * expression.cs: Pass location information to
2242 ConvertImplicitStandard.
2244 * class.cs: Added debugging code to track return values from
2247 2002-03-05 Miguel de Icaza <miguel@ximian.com>
2249 * expression.cs (Is.DoResolve): If either side of the `is' is an
2250 interface, do not flag the warning.
2252 * ecore.cs (ImplicitReferenceConversion): We need a separate test
2255 * report.cs: Allow for --fatal to be used with --probe.
2257 * typemanager.cs (NoTypes): Move the definition for the empty Type
2260 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
2262 (TypeContainer.DefineProxy): New function used to proxy to parent
2263 implementations when implementing interfaces.
2264 (TypeContainer.ParentImplements): used to lookup if our parent
2265 implements a public function that is required by an interface.
2266 (TypeContainer.VerifyPendingMethods): Hook this up.
2268 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
2269 `modules' and `assemblies' arraylists into arrays. We only grow
2270 these are the very early start up of the program, so this improves
2271 the speedof LookupType (nicely measured).
2273 * expression.cs (MakeByteBlob): Replaced unsafe code with
2274 BitConverter, as suggested by Paolo.
2276 * cfold.cs (ConstantFold.Binary): Special case: perform constant
2277 folding of string concatenation, but if either side is a string,
2278 and the other is not, then return null, and let the runtime use
2279 the concatenation on the string plus the object (using
2282 2002-03-04 Miguel de Icaza <miguel@ximian.com>
2284 Constant Folding has been implemented now.
2286 * expression.cs (Unary.Reduce): Do not throw an exception, catch
2287 the error instead on types that are not supported in one's
2290 * constant.cs (Constant and all children): New set of functions to
2291 perform implict and explicit conversions.
2293 * ecore.cs (EnumConstant): Implement the new functions to perform
2294 conversion by proxying to the child expression.
2296 * codegen.cs: (ConstantCheckState): Constant evaluation has its
2297 own separate setting that can not be turned off from the command
2298 line using --unchecked or --checked and is only controlled using
2299 the checked/unchecked statements and expressions. This setting is
2300 used by the constant folder to flag errors.
2302 * expression.cs (CheckedExpr, UncheckedExpr): Set the
2303 ConstantCheckState as well.
2305 During Resolve, they also have to flag the state, because the
2306 constant folder runs completely in the Resolve phase.
2308 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
2311 2002-03-01 Miguel de Icaza <miguel@ximian.com>
2313 * cfold.cs: New file, this file contains the constant folder.
2315 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
2316 argument to track whether we are using the resulting address to
2317 load or store a value and provide better error messages.
2319 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
2320 new AddressOf arguments.
2322 * statement.cs (Foreach.EmitCollectionForeach): Update
2324 * expression.cs (Argument.Emit): Call AddressOf with proper
2325 arguments to track usage.
2327 (New.DoEmit): Call AddressOf with new arguments.
2329 (Unary.Emit): Adjust AddressOf call.
2331 2002-03-01 Ravi Pratap <ravi@ximian.com>
2333 * cs-parser.jay (member_access): Change the case for pre-defined types
2334 to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
2337 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
2340 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
2341 essentially like methods and apply attributes like MethodImplOptions to them too.
2343 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
2346 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
2347 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
2350 * Update code everywhere accordingly.
2352 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
2354 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
2356 2002-02-28 Ravi Pratap <ravi@ximian.com>
2358 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
2359 try performing lookups against those instead of jumping straight into using
2360 the 'using' clauses.
2362 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
2364 (LookupType): Perform lookups in implicit parents too.
2366 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
2367 sequence as RootContext.LookupType.
2369 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
2370 the various cases of namespace lookups into this method.
2372 2002-03-01 Miguel de Icaza <miguel@ximian.com>
2374 * cs-parser.jay: Add support for [Attribute ()] (empty arguments
2375 in positional arguments)
2377 * class.cs (Operator): Update the AllowedModifiers to contain
2380 * cs-parser.jay: Update operator declaration to allow for the
2381 operator body to be empty.
2383 * cs-tokenizer.cs: Added '\u' unicode support in strings and hex
2386 2002-02-27 Miguel de Icaza <miguel@ximian.com>
2388 * class.cs (Method.Emit): Label parameters.
2390 * driver.cs: Return 1 or 0 as the program exit code.
2392 2002-02-26 Miguel de Icaza <miguel@ximian.com>
2394 * expression.cs: Special case the `null' object when trying to
2395 auto-compute the type, as anything can be explicitly converted to
2398 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
2399 spotting this Paolo.
2401 (Expression.ImplicitNumericConversion): Perform comparissions of
2402 the type using the underlying type in the case of an enumeration
2403 rather than using the enumeration type for the compare.
2405 Cope with the underlying == type case, which is not possible to
2408 (Expression.ConvertNumericExplicit): Perform comparissions of
2409 the type using the underlying type in the case of an enumeration
2410 rather than using the enumeration type for the compare.
2412 * driver.cs: If the user does not supply an extension, assume .exe
2414 * cs-parser.jay (if_statement): Rewrote so that we can track the
2415 location for the if statement.
2417 * expression.cs (Binary.ConstantFold): Only concat strings when
2418 the operation is "+", not everything ;-)
2420 * statement.cs (Statement.EmitBoolExpression): Take a location
2422 (If, While, Do): Track location.
2424 * expression.cs (Binary.ResolveOperator): In the object + string
2425 case, I was missing a call to ConvertImplicit
2427 2002-02-25 Ravi Pratap <ravi@ximian.com>
2429 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
2430 Location arguments. Ensure we use RootContext.LookupType to do our work
2431 and not try to do a direct Type.GetType and ModuleBuilder.GetType
2433 * interface.cs (PopulateMethod): Handle the type of the parameter being
2436 * expression.cs (Invocation.BetterFunction): Handle the case when we
2437 have a params method with no fixed arguments and a call is made with no
2440 2002-02-25 Miguel de Icaza <miguel@ximian.com>

2443 the verbatim-string-literal
2445 * support.cs (InternalParameters.ParameterModifier): handle null
2447 (InternalParameters.ParameterType): ditto.
2449 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
2450 duplicating the name of the variable parameter.
2451 (GetParameterByName): Fix bug where we were not looking up array
2452 paramters if they were the only present (thanks Paolo!).
2453 (GetParameterInfo): We only have an empty set of types if both
2454 fixed and array are set to null.
2455 (GetParameterInfo-idx): Handle FixedParameter == null
2457 * cs-parser.jay: Handle the case where there is no catch
2458 statements (missing null test).
2460 2002-02-22 Miguel de Icaza <miguel@ximian.com>
2462 * driver.cs (MainDriver): Be conservative on our command line
2465 Catch DirectoryNotFoundException when calling GetFiles.
2467 (SplitPathAndPattern): Used to split the input specification into
2468 a path and a pattern that we can feed to Directory.GetFiles.
2470 2002-02-21 Miguel de Icaza <miguel@ximian.com>
2472 * statement.cs (Fixed): Implement the last case of the Fixed
2473 statement (string handling).
2475 * expression.cs (StringPtr): New class used to return a char * to
2476 a string; Used by the Fixed statement.
2478 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
2480 * expression.cs (Binary.ResolveOperator): Remove redundant
2481 MemberLookup pn parent type.
2482 Optimize union call, we do not need a union if the types are the same.
2483 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
2486 Specialize the use of MemberLookup everywhere, instead of using
2487 the default settings.
2489 (StackAlloc): Implement stackalloc keyword.
2491 * cs-parser.jay: Add rule to parse stackalloc.
2493 * driver.cs: Handle /h, /help, /?
2495 * expression.cs (MakeByteBlob): Removed the hacks we had in place
2496 before we supported unsafe code.
2498 * makefile: add --unsafe to the self compilation of mcs.
2500 2002-02-20 Miguel de Icaza <miguel@ximian.com>
2502 * expression.cs (PointerArithmetic): New class that is used to
2503 perform pointer arithmetic.
2504 (Binary.Resolve): Handle pointer arithmetic
2505 Handle pointer comparission.
2506 (ArrayPtr): Utility expression class that is used to take the
2507 address of an array.
2509 (ElementAccess): Implement array access for pointers
2511 * statement.cs (Fixed): Implement fixed statement for arrays, we
2512 are missing one more case before we are done.
2514 * expression.cs (Indirection): Implement EmitAssign and set the
2515 ExprClass to Variable. This allows pointer dereferences to be
2516 treated as variables, and to have values assigned to them.
2518 * ecore.cs (Expression.StoreFromPtr): New utility function to
2519 store values dereferencing.
2521 2002-02-20 Ravi Pratap <ravi@ximian.com>
2523 * expression.cs (Binary.ResolveOperator): Ensure that we are
2524 not trying to operate on a void type - this fixes the reported
2527 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
2528 the parent implementation is sealed.
2530 * ../errors/cs0239.cs : Add.
2532 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
2534 * typemanager.cs (unverifiable_code_type): Corresponds to
2535 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
2536 which have unsafe code in them.
2538 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
2541 2002-02-19 Miguel de Icaza <miguel@ximian.com>
2543 * cs-tokenizer.cs: Add support for @"litreal strings"
2545 Make tokenizer accept pre-processor directives
2546 on any column (remove the old C-like limitation).
2548 * rootcontext.cs (EmitCode): Emit any global attributes.
2549 (AddGlobalAttributes): Used to keep track of assembly attributes.
2551 * attribute.cs (ApplyAttributes): Support AssemblyAttributes.
2553 * cs-parser.jay: Add support for global attributes.
2555 2002-02-17 Miguel de Icaza <miguel@ximian.com>
2557 * expression.cs (Indirection): New helper class. Unary will
2558 create Indirection classes to be able to implement the
2559 IMemoryLocation interface on it.
2561 2002-02-16 Miguel de Icaza <miguel@ximian.com>
2563 * cs-parser.jay (fixed_statement): reference the right statement.
2565 * statement.cs (Fixed.Emit): Finish implementing the fixed
2566 statement for the &x case.
2568 2002-02-14 Miguel de Icaza <miguel@ximian.com>
2570 * class.cs (Property.Define, Method.Define): Remove newslot when
2573 * modifiers.cs: My use of NewSlot when `Abstract' was set was
2574 wrong. NewSlot should only be used if the `new' keyword is present.
2576 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
2577 locating our system dir. Sorry about this.
2579 2002-02-13 Miguel de Icaza <miguel@ximian.com>
2581 * driver.cs (GetSystemDir): Compute correctly the location of our
2582 system assemblies. I was using the compiler directory instead of
2583 the library directory.
2585 2002-02-13 Ravi Pratap <ravi@ximian.com>
2587 * expression.cs (BetterFunction): Put back in what Miguel commented out
2588 since it is the correct fix. The problem is elsewhere ;-)
2590 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
2591 parameters of the parms method are themselves compatible or not !
2593 (StandardConversionExists): Fix very dangerous bug where we were forgetting
2594 to check that a class implements an interface before saying that an implicit
2595 conversion was allowed. Use ImplementsInterface to do the checking.
2597 2002-02-13 Miguel de Icaza <miguel@ximian.com>
2599 * class.cs (Method.Define): Track whether we are an explicit
2600 implementation or not. And only call DefineMethodOverride if we
2601 are an explicit implementation.
2603 (Property.DefineMethod): Ditto.
2605 2002-02-11 Ravi Pratap <ravi@ximian.com>
2607 * expression.cs (BetterFunction): Catch hideous bug which was
2608 preventing us from detecting ambiguous calls due to implicit casts i.e
2611 2002-01-29 Miguel de Icaza <miguel@ximian.com>
2613 * support.cs (Pair): Remove un-needed method. I figured why I was
2614 getting the error in cs-parser.jay, the variable in a foreach loop
2615 is readonly, and the compiler does not really treat this as a variable.
2617 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
2618 instead of EQUALS in grammar.
2620 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
2622 * expression.cs (Unary.DoResolve): Check whether the argument is
2625 2002-01-28 Miguel de Icaza <miguel@ximian.com>
2627 * support.cs: Api for Pair to set a value. Despite the fact that
2628 the variables are public the MS C# compiler refuses to compile
2629 code that accesses the field if the variable is part of a foreach
2632 * statement.cs (Fixed): Begin implementation of the fixed
2635 (Block.AddVariable): Return the VariableInfo on success and null
2636 on failure instead of true/false.
2638 * cs-parser.jay (foreach): Catch errors on variables already
2639 defined (we were ignoring this value before) and properly unwind
2642 (fixed_statement): grammar for the fixed statement.
2644 2002-01-25 Miguel de Icaza <miguel@ximian.com>
2646 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
2647 pointer types to be incretemented.
2649 (SizeOf): Implement.
2651 * cs-parser.jay (pointer_member_access): Implement
2652 expr->IDENTIFIER production.
2654 * expression.cs (IndexerAccess.DoResolve, ArrayAccess.DoResolve,
2655 MemberAccess.DoResolve, Invocation.DoResolve): Check for pointers
2658 (Unary): Implement indirection.
2660 * ecore.cs (Expression.UnsafeError): Reports error 214 (pointer
2661 use in non-unsafe context).
2663 (SimpleName.DoResolve): Check for pointers in field access on safe
2666 (Expression.LoadFromPtr): Factor the load-indirect code in this
2667 function. This was duplicated in UnboxCast and ParameterReference
2669 2002-01-24 Miguel de Icaza <miguel@ximian.com>
2671 * expression.cs (ComposedCast): report an error if a pointer cast
2672 is used in a safe region.
2674 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
2675 pointer type casts in unsafe context.
2677 * codegen.cs (EmitContext): Set up IsUnsafe.
2679 * cs-parser.jay (non_expression_type): Add productions for pointer
2682 * expression.cs (Invocation.EmitCall): Remove chunk of buggy
2683 code. We should not use force into static mode if the method is
2684 not virtual. Fixes bug in MIS
2686 * statement.cs (Do.Emit, While.Emit, For.Emit,
2687 Statement.EmitBoolExpression): Add support to Do and While to
2688 propagate infinite loop as `I do return' semantics.
2690 Improve the For case to also test for boolean constants.
2692 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
2693 to the list of attributes we can add.
2695 Remove `EmitContext' argument.
2697 * class.cs (Method.Define): Apply parameter attributes.
2698 (Constructor.Define): Apply parameter attributes.
2699 (MethodCore.LabelParameters): Move here the core of labeling
2702 * support.cs (ReflectionParameters.ParameterModifier,
2703 InternalParameters.ParameterModifier): Use IsByRef on the type and
2704 only return the OUT bit for these parameters instead of in/out/ref
2707 This is because I miss-understood things. The ParameterInfo.IsIn
2708 and IsOut represent whether the parameter has the [In] and [Out]
2711 2002-01-22 Miguel de Icaza <miguel@ximian.com>
2713 * ecore.cs (FieldExpr.Emit): Release temporaries.
2715 * assign.cs (LocalTemporary.Release): new function.
2717 * codegen.cs (EmitContext.GetTemporaryStorage,
2718 EmitContext.FreeTemporaryStorage): Rework the way we deal with
2719 temporary storage. Now we can "put back" localbuilders when we
2722 2002-01-21 Miguel de Icaza <miguel@ximian.com>
2724 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
2725 need to make a copy of the variable to generate verifiable code.
2727 2002-01-19 Miguel de Icaza <miguel@ximian.com>
2729 * driver.cs: Compute dynamically the system directory.
2731 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
2732 Slower, but more generally useful. Used by the abstract
2733 registering implementation.
2735 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
2736 the rules for the special rule on Type/instances. First check if
2737 we have the same name, and if so, try that special static path
2738 rather than the instance path.
2740 2002-01-18 Miguel de Icaza <miguel@ximian.com>
2742 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
2745 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
2746 Enum, ValueType, Delegate or Array for non-corlib compiles.
2748 * cs-tokenizer.cs: Catch long identifiers (645)
2750 * typemanager.cs (IndexerPropetyName): Ravi never tested this
2753 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
2754 fix, we were returning too early, so we were not registering
2755 pending methods from abstract classes.
2757 Do not register pending methods if the class is abstract.
2759 * expression.cs (Conditional.DoResolve): Report circular implicit
2760 conversions when we neecd to compute it for conditional
2763 (Is.DoResolve): If the expression is always of the provided type,
2764 flag warning 183. If the expression can not ever be of the
2765 provided type flag warning 184.
2767 * class.cs: Catch 169 as well.
2769 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
2772 2002-01-18 Nick Drochak <ndrochak@gol.com>
2774 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.
2776 2002-01-17 Miguel de Icaza <miguel@ximian.com>
2778 * interface.cs: (PopulateMethod): Check for pointers being defined
2779 only if the unsafe context is active.
2780 (PopulateProperty): ditto.
2781 (PopulateIndexer): ditto.
2783 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
2784 specified. If pointers are present, make sure that they are
2785 present in an unsafe context.
2786 (Constructor, Constructor.Define): ditto.
2787 (Field, Field.Define): ditto.
2788 (Property, Property.Define): ditto.
2789 (Event, Event.Define): ditto.
2791 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
2792 hashtable if there are classes or structs defined.
2794 * expression.cs (LocalVariableReference.DoResolve): Simplify this
2795 code, as the constant resolution moved.
2797 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
2798 the metadata, so we can flag error 133.
2800 * decl.cs (MemberCore.UnsafeOK): New function to test that a
2801 pointer is being declared in an unsafe context.
2803 2002-01-16 Miguel de Icaza <miguel@ximian.com>
2805 * modifiers.cs (Modifiers.Check): Require a Location argument.
2806 Report error 227 for Unsafe use.
2808 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
2810 * statement.cs (For.Emit): If the test is null, then report that
2811 we do `return', as we wont reach anything afterwards.
2813 (Switch.SwitchGoverningType): Track the expression that matched
2816 * driver.cs: Allow negative numbers as an error code to flag.
2818 * cs-parser.jay: Handle 1551.
2820 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
2822 2002-01-15 Miguel de Icaza <miguel@ximian.com>
2824 * cs-parser.jay: Report 1518 (type declaration can only contain
2825 class, struct, interface, enum or delegate)
2827 (switch_label): Report 1523 (keywords `case' or `default' must
2830 (opt_switch_sections): Report 1522 (empty switch)
2832 * driver.cs: Report 1515 (response file specified multiple times)
2833 Report 1516 (Source file specified multiple times).
2835 * expression.cs (Argument.Resolve): Signal 1510
2837 (BaseAccess.Resolve, BaseIndexer.Resolve): Signal 1511 (base
2838 access not allowed in static code)
2840 2002-01-11 Ravi Pratap <ravi@ximian.com>
2842 * typemanager.cs (IsPointerType): Utility method which we are going
2845 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
2846 the object type, so we take care of that.
2848 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
2850 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
2851 added to non-params parameters :-)
2853 * typemanager.cs (CSharpName): Include 'void' type too.
2855 (void_ptr_type): Include in the set of core types.
2857 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
2860 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
2863 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
2864 completely forgotten about it.
2866 2002-01-10 Ravi Pratap <ravi@ximian.com>
2868 * cs-parser.jay (pointer_type): Add. This begins our implementation
2869 of parsing rules for unsafe code.
2871 (unsafe_statement): Implement.
2873 (embedded_statement): Modify to include the above.
2875 * statement.cs (Unsafe): Implement new class for unsafe blocks.
2877 * codegen.cs (EmitContext.InUnsafe): Add. This determines
2878 if the current context is an unsafe one.
2880 * cs-parser.jay (local_variable_pointer_type): Since local variable types
2881 are handled differently, we need separate rules for them.
2883 (local_variable_declaration): Update to use local_variable_pointer_type
2884 to allow variable declarations of unmanaged pointer types.
2886 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
2889 * ../errors/cs0214.cs : Add.
2891 2002-01-16 Nick Drochak <ndrochak@gol.com>
2893 * makefile: remove 'response' file when cleaning.
2895 2002-01-15 Miguel de Icaza <miguel@ximian.com>
2897 * cs-parser.jay: Report 1524.
2899 2002-01-14 Miguel de Icaza <miguel@ximian.com>
2901 * typemanager.cs (RegisterMethod): drop checking if we have
2902 registered this from here
2904 2002-01-12 Miguel de Icaza <miguel@ximian.com>
2906 * class.cs (Method.EmitDestructor): Implement calling our base
2909 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
2912 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
2913 this routine and will wrap the call in a try/catch block. Deal
2916 2002-01-11 Miguel de Icaza <miguel@ximian.com>
2918 * ecore.cs (Expression.MemberLookup): instead of taking a
2919 parameter `same_type' that was used to tell whether we could
2920 access private members we compute our containing type from the
2923 (FieldExpr): Added partial support for volatile fields. This does
2924 not work for volatile fields exposed from assemblies, as I can not
2925 figure out how to extract the modreq from it.
2927 Updated all the source files to use this.
2929 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
2930 because it is referenced by MemberLookup very often.
2932 2002-01-09 Ravi Pratap <ravi@ximian.com>
2934 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
2935 TypeBuilder.GetCustomAttributes to retrieve what we need.
2937 Get rid of redundant default_member_attr_type as this is the same as
2938 default_member_type which already exists.
2940 * interface.cs, attribute.cs : Update accordingly.
2942 2002-01-08 Miguel de Icaza <miguel@ximian.com>
2944 * typemanager.cs: Enable IndexerPropertyName again. It does not
2945 work for TYpeBuilders though. Ravi, can you please fix this?
2947 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
2949 * expression.cs (Argument.Emit): Handle the case of ref objects
2950 being passed to ref functions;
2952 (ParameterReference.EmitLoad): Loads the content of the pointer
2953 without dereferencing.
2955 2002-01-07 Miguel de Icaza <miguel@ximian.com>
2957 * cs-tokenizer.cs: Implemented the pre-processing expressions.
2959 2002-01-08 Ravi Pratap <ravi@ximian.com>
2961 * class.cs (Indexer.DefineMethod): Incorporate the interface
2962 type in the name of the method if we are doing explicit interface
2965 * expression.cs (ConversionExists): Remove as it is completely obsolete.
2967 (BetterConversion): Fix extremely trivial bug where we were referring to
2968 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
2971 * ../errors/bug16.cs : Add although we have fixed it.
2973 2002-01-07 Miguel de Icaza <miguel@ximian.com>
2975 * expression.cs (BaseIndexer): Begin implementation.
2977 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
2979 * cs-parser.jay (indexer_declarator): Use qualified_identifier
2980 production directly to remove a shift/reduce, and implement
2981 explicit interface implementation.
2983 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
2984 after a floating point suffix.
2986 * expression.cs (DoNumericPromotions): Improved the conversion for
2987 uint/uint. If we have a constant, we avoid doing a typecast to a
2990 * class.cs (Indexer): Implement explicit interface implementation
2993 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
2995 * class.cs: make the default instance constructor public and hidebysig.
2997 2001-01-03 Ravi Pratap <ravi@ximian.com>
2999 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
3000 so we can call it from elsewhere.
3002 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
3003 we emit it internally if the class has a defined indexer; otherwise the user
3004 emits it by decorating the class definition with the DefaultMemberAttribute.
3006 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
3007 attribute is not used on a type which defines an indexer.
3009 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
3010 character when we skip whitespace.
3012 * ../errors/cs0646.cs : Add.
3014 2002-01-03 Miguel de Icaza <miguel@ximian.com>
3016 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
3019 * makefile: Add practical target `mcs3.exe' which builds the third
3020 generation compiler.
3022 * expression.cs (New): Fix structures constructor calling.
3024 * class.cs (Property, Method, Indexer): Emit Final flag on the
3025 method if we are an interface implementation and we are not
3028 * ecore.cs (PropertyExpr): New public field `IsBase', tells
3029 whether this property is referencing a `base' method.
3031 * expression.cs (Invocation.EmitCall): take an extra argument:
3032 is_base, this is used to determine whether the `call' or
3033 `callvirt' opcode should be used.
3036 * delegate.cs: update EmitCall.
3038 * class.cs (Method.Define): Set NewSlot for the cases where we are
3039 not implementing an interface method.
3041 (Property.Define): ditto.
3043 2002-01-02 Miguel de Icaza <miguel@ximian.com>
3045 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
3046 'r'. Allows mcs to parse itself fully.
3048 2002-01-02 Ravi Pratap <ravi@ximian.com>
3050 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
3051 of the number of initializers that require the InitializeArray method.
3053 (CheckIndices): Store the Expression in all cases - not the plain value. Also
3054 update the above field where necessary.
3056 (MakeByteBlob): Update accordingly.
3058 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
3061 (EmitDynamicInitializers): Update in accordance with the new optimization.
3063 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
3064 same OpCode applies.
3066 * cs-parser.jay : Fix some glaring errors I introduced.
3068 2002-01-01 Ravi Pratap <ravi@ximian.com>
3070 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
3071 so that we can check for name clashes there too.
3073 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
3074 for interface indexers.
3076 * interfaces.cs (Define): Emit the default member attribute.
3078 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
3079 variable was being referred to while setting the value ;-)
3081 2002-01-01 Miguel de Icaza <miguel@ximian.com>
3083 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
3084 byte-by-byte information when we know the data is zero.
3086 Make the block always a multiple of 4, because
3087 DefineInitializedData has a bug.
3089 * assign.cs: Fix, we should assign from the temporary, not from
3092 * expression.cs (MakeByteBlob): Fix my incorrect code.
3094 2001-12-31 Miguel de Icaza <miguel@ximian.com>
3096 * typemanager.cs (EnumToUnderlying): This function is used to get
3097 the underlying type from an enumeration, because it does not
3100 * constant.cs: Use the I4_S form for values between -128 and 127.
3102 * statement.cs (Block.LookupLabel): Looks up a label.
3103 (Block): Drop support for labeled blocks.
3105 (LabeledStatement): New kind of statement that represents a label
3108 (Goto): Finally implement this bad boy.
3110 * cs-parser.jay: Update to reflect new mechanism to implement
3113 2001-12-30 Miguel de Icaza <miguel@ximian.com>
3115 * codegen.cs (EmitContext.This): a codegen property that keeps the
3116 a single instance of this instead of creating many different this
3119 * delegate.cs (Delegate.DoResolve): Update to use the property;
3121 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
3123 * expression.cs (BaseAccess.DoResolve): Ditto.
3125 2001-12-29 Ravi Pratap <ravi@ximian.com>
3127 * typemanager.cs (methodimpl_attr_type): Add to hold the type
3128 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
3130 (InitCoreTypes): Update accordingly.
3132 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
3133 so we can quickly store the state.
3135 (ApplyAttributes): Set the correct implementation flags
3136 for InternalCall methods.
3138 2001-12-29 Miguel de Icaza <miguel@ximian.com>
3140 * expression.cs (EmitCall): if a method is not virtual, then do
3141 not use callvirt on it.
3143 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
3144 user defined stuff) requires the use of stobj, which takes an
3145 address on the stack instead of an array and an index. So emit
3146 the Ldelema operation for it.
3148 (EmitStoreOpcode): Use stobj for valuetypes.
3150 (UnaryMutator.EmitCode): Use the right 1 value depending on
3151 whether we are dealing with int64/uint64, float or doubles.
3153 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
3154 constructors that I implemented last night.
3156 (Constructor.IsDefault): Fix to work properly for static
3159 * cs-parser.jay (CheckDef): report method signature errors.
3160 Update error number 103 to be 132.
3162 * decl.cs: New AdditionResult enumeration value: MethodExists.
3163 Although we do this check for methods later on in the semantic
3164 analysis, catching repeated default constructors is so easy that
3165 we catch these here.
3167 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
3170 (ParameterReference.EmitAssign, Emit): handle
3173 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
3174 (ArrayAccess.EmitStoreOpcode): ditto.
3176 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
3178 * expression.cs (MakeByteBlob): Complete all the missing types
3179 (uint, short, ushort, byte, sbyte)
3181 * class.cs: Only init instance field initializers on instance
3184 Rename `constructors' to instance_constructors.
3186 (TypeContainer.AddConstructor): Only add constructors to the list
3187 if it is not static.
3189 Make sure that we handle default_static_constructor independently
3190 everywhere where we handle instance_constructors
3192 2001-12-28 Miguel de Icaza <miguel@ximian.com>
3194 * class.cs: Do not lookup or create a base initializer for a
3197 (ConstructorInitializer.Resolve): use the proper type to lookup
3200 * cs-parser.jay: Report error 1585 (modifiers between type and name).
3202 * enum.cs, interface.cs: Remove CloseType, this is taken care by
3205 * decl.cs: CloseType is now an virtual method, the default
3206 implementation just closes this type.
3208 2001-12-28 Ravi Pratap <ravi@ximian.com>
3210 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
3211 to PreserveSig by default. Also emit HideBySig on such methods.
3213 Basically, set the defaults to standard values.
3215 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
3216 argument, if candidate is better, it can't be worse than the best !
3218 (Invocation): Re-write bits to differentiate between methods being
3219 applicable in their expanded form and their normal form - for params
3222 Get rid of use_standard everywhere as only standard conversions are allowed
3223 in overload resolution.
3225 More spec conformance.
3227 2001-12-27 Miguel de Icaza <miguel@ximian.com>
3229 * driver.cs: Add --timestamp, to see where the compiler spends
3232 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
3233 `this' in static code.
3235 (SimpleName.DoResolve): Implement in terms of a helper function
3236 that allows static-references to be passed upstream to
3239 (Expression.ResolveWithSimpleName): Resolve specially simple
3240 names when called by MemberAccess to implement the special
3243 (Expression.ImplicitReferenceConversion): Handle conversions from
3244 Null to reference types before others, as Null's type is
3247 * expression.cs (Invocation.EmitCall): Handle the special case of
3248 calling methods declared on a reference type from a ValueType
3249 (Base classes System.Object and System.Enum)
3251 (MemberAccess.Resolve): Only perform lookups on Enumerations if
3252 the left hand side is a TypeExpr, not on every enumeration.
3254 (Binary.Resolve): If types are reference types, then do a cast to
3255 object on operators != and == of both arguments.
3257 * typemanager.cs (FindMembers): Extract instance and static
3258 members if requested.
3260 * interface.cs (PopulateProperty): Use void_type instead of null
3261 as the return type for the setter method.
3263 (PopulateIndexer): ditto.
3265 2001-12-27 Ravi Pratap <ravi@ximian.com>
3267 * support.cs (ReflectionParameters): Fix minor bug where we
3268 were examining the wrong parameter for the ParamArray attribute.
3270 Cope with requests for the type of the parameter at position
3271 greater than the params parameter's. We now return the element
3272 type of the params array as that makes more sense.
3274 * expression.cs (Invocation.IsParamsMethodApplicable): Update
3275 accordingly as we no longer have to extract the element type
3278 (Invocation.OverloadResolve): Update.
3280 2001-12-27 Miguel de Icaza <miguel@ximian.com>
3282 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
3283 against IEnumerator, test whether the return value is a descendant
3284 of the IEnumerator interface.
3286 * class.cs (Indexer.Define): Use an auxiliary method to implement
3287 the other bits of the method definition. Begin support for
3288 explicit interface implementation.
3290 (Property.DefineMethod): Use TypeManager.void_type instead of null
3291 for an empty return value.
3293 2001-12-26 Miguel de Icaza <miguel@ximian.com>
3295 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
3296 dealing with a FieldExpr which is composed of a FieldBuilder, in
3297 the code path we did extract the constant, but we should have
3298 obtained the underlying value to be able to cast it (otherwise we
3299 end up in an infinite loop, this is what Ravi was running into).
3301 (ArrayCreation.UpdateIndices): Arrays might be empty.
3303 (MemberAccess.ResolveMemberAccess): Add support for section
3304 14.5.4.1 that deals with the special case of E.I when E is a type
3305 and something else, that I can be a reference to a static member.
3307 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
3308 handle a particular array type to create byte blobs, it is just
3309 something we dont generate byteblobs for.
3311 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
3314 * location.cs (Push): remove the key from the hashtable that we
3315 are about to add. This happens for empty files.
3317 * driver.cs: Dispose files after we have parsed them.
3319 (tokenize): new function that only runs the tokenizer on its
3320 input, for speed testing.
3322 2001-12-26 Ravi Pratap <ravi@ximian.com>
3324 * class.cs (Event.Define): Define the private field only if there
3325 are no accessors defined.
3327 * expression.cs (ResolveMemberAccess): If there is no associated
3328 field with the event, that means we have an event defined with its
3329 own accessors and we should flag error cs0070 since transforming
3330 ourselves into a field is not valid in that case.
3332 * ecore.cs (SimpleName.DoResolve): Same as above.
3334 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
3335 and charset to sane values.
3337 2001-12-25 Ravi Pratap <ravi@ximian.com>
3339 * assign.cs (DoResolve): Perform check on events only if they
3340 are being accessed outside the declaring type.
3342 * cs-parser.jay (event_declarations): Update rules to correctly
3343 set the type of the implicit parameter etc.
3345 (add_accessor, remove_accessor): Set current local parameters.
3347 * expression.cs (Binary): For delegate addition and subtraction,
3348 cast the return value from the method into the appropriate delegate
3351 2001-12-24 Ravi Pratap <ravi@ximian.com>
3353 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
3354 of these as the workaround is unnecessary.
3356 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
3357 delegate data - none of that is needed at all.
3359 Re-write bits to extract the instance expression and the delegate method
3362 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
3365 * attribute.cs (ApplyAttributes): New method to take care of common tasks
3366 of attaching attributes instead of duplicating code everywhere.
3368 * everywhere : Update code to do attribute emission using the above method.
3370 2001-12-23 Miguel de Icaza <miguel@ximian.com>
3372 * expression.cs (IsParamsMethodApplicable): if there are not
3373 parameters, return immediately.
3375 * ecore.cs: The 0 literal can be implicity converted to an enum
3378 (SimpleName.DoResolve): First lookup the type, then lookup the
3381 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
3382 want to get its address. If the InstanceExpression is not
3383 addressable, store the result in a temporary variable, then get
3386 * codegen.cs: Only display 219 errors on warning level or above.
3388 * expression.cs (ArrayAccess): Make it implement the
3389 IMemoryLocation interface.
3391 (Binary.DoResolve): handle the operator == (object a, object b)
3392 and operator != (object a, object b) without incurring into a
3393 BoxedCast (because 5 != o should never be performed).
3395 Handle binary enumerator operators.
3397 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
3398 value type, otherwise use Ldelem_ref.
3400 Use precomputed names;
3402 (AddressOf): Implement address of
3404 * cs-parser.jay (labeled_statement): Fix recursive block
3405 addition by reworking the production.
3407 * expression.cs (New.DoEmit): New has a special case:
3409 If we are dealing with a ValueType, we have a few
3410 situations to deal with:
3412 * The target of New is a ValueType variable, that is
3413 easy, we just pass this as the variable reference
3415 * The target of New is being passed as an argument,
3416 to a boxing operation or a function that takes a
3419 In this case, we need to create a temporary variable
3420 that is the argument of New.
3423 2001-12-23 Ravi Pratap <ravi@ximian.com>
3425 * rootcontext.cs (LookupType): Check that current_type is not null before
3426 going about looking at nested types.
3428 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
3429 not implement the IAssignMethod interface any more.
3431 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
3432 where we tranform them into FieldExprs if they are being resolved from within
3435 * ecore.cs (SimpleName.DoResolve): Do the same here.
3437 * assign.cs (DoResolve, Emit): Clean up code considerably.
3439 * ../errors/bug10.cs : Add.
3441 * ../errors/cs0070.cs : Add.
3443 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
3445 * assign.cs : Get rid of EventIsLocal everywhere.
3447 2001-12-23 Miguel de Icaza <miguel@ximian.com>
3449 * ecore.cs (ConvertIntLiteral): finished the implementation.
3451 * statement.cs (SwitchLabel): Convert the value we are using as a
3452 key before looking up the table.
3454 2001-12-22 Miguel de Icaza <miguel@ximian.com>
3456 * codegen.cs (EmitTopBlock): Require a Location argument now.
3458 * cs-parser.jay (constructor_declarator): We need to setup
3459 current_local_parameters before we parse the
3460 opt_constructor_initializer, to allow the variables to be bound
3461 to the constructor arguments.
3463 * rootcontext.cs (LookupType): First lookup nested classes in our
3464 class and our parents before we go looking outside our class.
3466 * expression.cs (ConstantFold): Extract/debox the values at the
3469 * rootcontext.cs (EmitCode): Resolve the constants first before we
3470 resolve the types. This is not really needed, but it helps debugging.
3472 * statement.cs: report location.
3474 * cs-parser.jay: pass location to throw statement.
3476 * driver.cs: Small bug fix.
3478 * report.cs: Updated format to be 4-zero filled digits.
3480 2001-12-22 Ravi Pratap <ravi@ximian.com>
3482 * expression.cs (CheckIndices): Fix minor bug where the wrong
3483 variable was being referred to ;-)
3485 (DoEmit): Do not call EmitStaticInitializers when the
3486 underlying type is System.Object.
3488 2001-12-21 Ravi Pratap <ravi@ximian.com>
3490 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
3491 and do the usual workaround for SRE.
3493 * class.cs (MyEventBuilder.EventType): New member to get at the type
3494 of the event, quickly.
3496 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
3498 * assign.cs (Assign.DoResolve): Handle the case when the target
3499 is an EventExpr and perform the necessary checks.
3501 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
3504 (SimpleName.MemberStaticCheck): Include check for EventExpr.
3506 (EventExpr): Set the type in the constructor itself since we
3507 are meant to be born fully resolved.
3509 (EventExpr.Define): Revert code I wrote earlier.
3511 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
3512 instance expression is null. The instance expression is a This in that case
3513 or a null, depending on whether it is a static method or not.
3515 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
3516 refers to more than one method.
3518 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
3519 and accordingly flag errors.
3521 2001-12-21 Miguel de Icaza <miguel@ximian.com>
3523 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
3525 2001-12-22 Miguel de Icaza <miguel@ximian.com>
3527 * location.cs (ToString): Provide useful rutine.
3529 2001-12-21 Miguel de Icaza <miguel@ximian.com>
3531 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
3532 objects, return the actual integral boxed.
3534 * statement.cs (SwitchLabel): define an ILLabel for each
3537 (Switch.CheckSwitch): If the value is a Literal, extract
3538 the underlying literal.
3540 Also in the unused hashtable we had, add the SwitchLabel so we can
3541 quickly look this value up.
3543 * constant.cs: Implement a bunch of new constants. Rewrite
3544 Literal based on this. Made changes everywhere to adapt to this.
3546 * expression.cs (Expression.MakeByteBlob): Optimize routine by
3547 dereferencing array only once, and also copes with enumrations.
3549 bytes are two bytes wide, not one.
3551 (Cast): Perform constant conversions.
3553 * ecore.cs (TryImplicitIntConversion): Return literals instead of
3554 wrappers to the literals here.
3556 * expression.cs (DoNumericPromotions): long literals can converted
3557 to ulong implicity (this is taken care of elsewhere, but I was
3560 * ecore.cs (Expression.Literalize): Make the return type Literal,
3561 to improve type checking.
3563 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
3565 2001-12-20 Miguel de Icaza <miguel@ximian.com>
3567 * literal.cs: Revert code from ravi that checked the bounds. The
3568 bounds are sane by the definition of the type itself.
3570 * typemanager.cs: Fix implementation of ImplementsInterface. We
3571 need to actually look up in our parent hierarchy for interfaces
3574 * const.cs: Use the underlying type for enumerations
3576 * delegate.cs: Compute the basename for the delegate creation,
3577 that should fix the delegate test case, and restore the correct
3578 Type Lookup semantics in rootcontext
3580 * rootcontext.cs: Revert Ravi's last patch. The correct way of
3581 referencing a nested type with the Reflection API is using the "+"
3584 * cs-parser.jay: Do not require EOF token at the end.
3586 2001-12-20 Ravi Pratap <ravi@ximian.com>
3588 * rootcontext.cs (LookupType): Concatenate type names with
3589 a '.' instead of a '+' The test suite passes again.
3591 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
3592 field of the enumeration.
3594 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
3595 the case when the member is an EventExpr.
3597 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
3598 static has an associated instance expression.
3600 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
3602 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
3604 * class.cs (Event.Define): Register event and perform appropriate checks
3607 We define the Add and Remove methods even if the use provides none because
3608 in that case, we provide default implementations ourselves.
3610 Define a private field of the type of the event. This is done by the CSC compiler
3611 and we should be doing it too ;-)
3613 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
3614 More methods we use in code we generate.
3616 (multicast_delegate_type, delegate_type): Two separate types since the distinction
3619 (InitCoreTypes): Update accordingly for the above.
3621 * class.cs (Event.Emit): Generate code for default accessors that we provide
3623 (EmitDefaultMethod): Do the job in the above.
3625 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
3628 2001-12-20 Miguel de Icaza <miguel@ximian.com>
3630 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
3631 builders even if we were missing one.
3633 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
3634 pass the Basename as our class name instead of the Name. The
3635 basename will be correctly composed for us.
3637 * parameter.cs (Paramters): Now takes a Location argument.
3639 * decl.cs (DeclSpace.LookupType): Removed convenience function and
3640 make all the code call directly LookupType in RootContext and take
3641 this chance to pass the Location information everywhere.
3643 * Everywhere: pass Location information.
3645 2001-12-19 Miguel de Icaza <miguel@ximian.com>
3647 * class.cs (Constructor.Define): Updated way of detecting the
3648 length of the parameters.
3650 (TypeContainer.DefineType): Use basename as the type name for
3653 (TypeContainer.Define): Do not recursively define types here, as
3654 definition is taken care in order by the RootContext.
3656 * tree.cs: Keep track of namespaces in a per-file basis.
3658 * parameter.cs (Parameter.ComputeSignature): Update to use
3661 (Parameters.GetSignature): ditto.
3663 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
3664 instead of a TypeContainer.
3666 (Interface.SemanticAnalysis): Use `this' instead of our parent to
3667 resolve names. Because we need to be resolve in our context, not
3670 * driver.cs: Implement response files.
3672 * class.cs (TypeContainer.DefineType): If we are defined, do not
3675 (Event.Emit): Emit the code for add/remove handlers.
3676 (Event.Define): Save the MethodBuilders for add/remove.
3678 * typemanager.cs: Use pair here too.
3680 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
3681 DictionaryEntry requires the first argument to be non-null.
3683 (enum_declaration): Compute full name for registering the
3686 (delegate_declaration): Instead of using
3687 formal_parameter_list, use opt_formal_parameter_list as the list
3690 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
3691 (EventParsing): New property that controls whether `add' and
3692 `remove' are returned as tokens or identifiers (for events);
3694 2001-12-19 Ravi Pratap <ravi@ximian.com>
3696 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
3697 use MyEventBuilder only and let it wrap the real builder for us.
3699 (MyEventBuilder): Revamp constructor etc.
3701 Implement all operations that we perform on EventBuilder in precisely the same
3704 (FindMembers): Update to use the EventBuilder member.
3706 (Event.Emit): Update accordingly.
3708 2001-12-18 Ravi Pratap <ravi@ximian.com>
3710 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
3711 by calling the appropriate methods.
3713 (GetCustomAttributes): Make stubs as they cannot possibly do anything
3716 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
3718 2001-12-17 Ravi Pratap <ravi@ximian.com>
3720 * delegate.cs (Delegate.Populate): Check that the return type
3721 and various parameters types are indeed accessible.
3723 * class.cs (Constructor.Define): Same here.
3725 (Field.Define): Ditto.
3727 (Event.Define): Ditto.
3729 (Operator.Define): Check that the underlying Method defined itself
3730 correctly - so it's MethodBuilder should not be null.
3732 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
3733 expression happens to be null.
3735 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
3736 members but as of now we don't seem to be able to do anything really useful with it.
3738 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
3739 not the EventBuilder.
3741 2001-12-18 Miguel de Icaza <miguel@ximian.com>
3743 * cs-tokenizer.cs: Add support for defines.
3744 Add support for #if, #elif, #else, #endif
3746 (eval_var): evaluates a variable.
3747 (eval): stubbed for evaluating functions.
3749 * cs-parser.jay: Pass the defines information
3751 * driver.cs: Add --define command line option.
3753 * decl.cs: Move MemberCore here.
3755 Make it the base class for DeclSpace. This allows us to catch and
3756 report 108 and 109 for everything now.
3758 * class.cs (TypeContainer.Define): Extract all the members
3759 before populating and emit the warning 108 (new keyword required
3760 to override) instead of having each member implement this.
3762 (MemberCore.Define): New abstract method, we will be using this in
3763 the warning reporting engine in Populate.
3765 (Operator.Define): Adjust to new MemberCore protocol.
3767 * const.cs (Const): This does not derive from Expression, it is a
3768 temporary object we use to create fields, it is a MemberCore.
3770 * class.cs (Method.Define): Allow the entry point to be in a
3773 * driver.cs: Rewrite the argument handler to clean it up a bit.
3775 * rootcontext.cs: Made it just an auxiliary namespace feature by
3776 making everything static.
3778 * driver.cs: Adapt code to use RootContext type name instead of
3781 * delegate.cs: Remove RootContext argument.
3783 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
3786 * class.cs (Event.Define): The lookup can fail.
3788 * cs-tokenizer.cs: Begin implementation of pre-procesor.
3790 * expression.cs: Resolve the this instance before invoking the code.
3792 2001-12-17 Miguel de Icaza <miguel@ximian.com>
3794 * cs-parser.jay: Add a production in element_access that allows
3795 the thing to become a "type" reference. This way we can parse
3796 things like "(string [])" as a type.
3798 Note that this still does not handle the more complex rules of
3802 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
3804 * ecore.cs: (CopyNewMethods): new utility function used to
3805 assemble the list of methods from running FindMembers.
3807 (MemberLookup): Rework FindMembers so that
3809 2001-12-16 Miguel de Icaza <miguel@ximian.com>
3811 * class.cs (TypeContainer): Remove Delegates who fail to be
3814 * delegate.cs (Populate): Verify that we dont get null return
3815 values. TODO: Check for AsAccessible.
3817 * cs-parser.jay: Use basename to emit error 574 (destructor should
3818 have the same name as container class), not the full name.
3820 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
3821 possible representation.
3823 Also implements integer type suffixes U and L.
3825 2001-12-15 Miguel de Icaza <miguel@ximian.com>
3827 * expression.cs (ArrayCreation.DoResolve): We need to do the
3828 argument resolution *always*.
3830 * decl.cs: Make this hold the namespace. Hold the root context as
3832 (LookupType): Move here.
3834 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
3836 * location.cs (Row, Name): Fixed the code, it was always returning
3837 references to the first file.
3839 * interface.cs: Register properties defined through interfaces.
3841 * driver.cs: Add support for globbing on the command line
3843 * class.cs (Field): Make it derive from MemberCore as well.
3846 2001-12-15 Ravi Pratap <ravi@ximian.com>
3848 * class.cs (Event::Define): Check that the type of the event is a delegate
3849 type else flag error #66.
3851 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
3854 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
3855 values of EntryPoint, CharSet etc etc.
3857 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
3859 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
3860 be null and we should ignore this. I am not sure if this is really clean. Apparently,
3861 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
3862 which needs this to do its work.
3864 * ../errors/cs0066.cs : Add.
3866 2001-12-14 Miguel de Icaza <miguel@ximian.com>
3868 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
3871 * class.cs: (MethodSignature.MethodSignature): Removed hack that
3872 clears out the parameters field.
3873 (MemberSignatureCompare): Cleanup
3875 (MemberCore): New base class used to share code between MethodCore
3878 (RegisterRequiredImplementations) BindingFlags.Public requires
3879 either BindingFlags.Instace or Static. Use instance here.
3881 (Property): Refactored code to cope better with the full spec.
3883 * parameter.cs (GetParameterInfo): Return an empty array instead
3886 * class.cs (Property): Abstract or extern properties have no bodies.
3888 * parameter.cs (GetParameterInfo): return a zero-sized array.
3890 * class.cs (TypeContainer.MethodModifiersValid): Move all the
3891 method modifier validation to the typecontainer so we can reuse
3894 (MethodCore.ParameterTypes): return an empty sized array of types.
3896 (Property.Define): Test property modifier validity.
3898 Add tests for sealed/override too.
3900 (Method.Emit): abstract or extern methods have no bodies.
3902 2001-12-14 Ravi Pratap <ravi@ximian.com>
3904 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
3907 (Method::Define, ::Emit): Modify accordingly.
3909 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
3911 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
3913 * makefile: Pass in /unsafe.
3915 2001-12-13 Miguel de Icaza <miguel@ximian.com>
3917 * class.cs (MakeKey): Kill routine.
3919 * class.cs (TypeContainer.Define): Correctly define explicit
3920 method implementations (they require the full interface name plus
3923 * typemanager.cs: Deply the PtrHashtable here and stop using the
3924 lame keys. Things work so much better.
3926 This of course broke everyone who depended on `RegisterMethod' to
3927 do the `test for existance' test. This has to be done elsewhere.
3929 * support.cs (PtrHashtable): A hashtable that avoid comparing with
3930 the object stupid Equals method (because, that like fails all over
3931 the place). We still do not use it.
3933 * class.cs (TypeContainer.SetRequiredInterface,
3934 TypeContainer.RequireMethods): Killed these two routines and moved
3935 all the functionality to RegisterRequiredImplementations.
3937 (TypeContainer.RegisterRequiredImplementations): This routine now
3938 registers all the implementations required in an array for the
3939 interfaces and abstract methods. We use an array of structures
3940 which can be computed ahead of time to reduce memory usage and we
3941 also assume that lookups are cheap as most classes will not
3942 implement too many interfaces.
3944 We also avoid creating too many MethodSignatures.
3946 (TypeContainer.IsInterfaceMethod): Update and optionally does not
3947 clear the "pending" bit if we find that there are problems with
3950 (TypeContainer.VerifyPendingMethods): Update to report errors of
3951 methods that look like implementations but are not.
3953 (TypeContainer.Define): Add support for explicit interface method
3956 2001-12-12 Miguel de Icaza <miguel@ximian.com>
3958 * typemanager.cs: Keep track of the parameters here instead of
3959 being a feature of the TypeContainer.
3961 * class.cs: Drop the registration of parameters here, as
3962 InterfaceMethods are also interface declarations.
3964 * delegate.cs: Register methods with the TypeManager not only with
3965 the TypeContainer. This code was buggy.
3967 * interface.cs: Full registation here.
3969 2001-12-11 Miguel de Icaza <miguel@ximian.com>
3971 * expression.cs: Remove reducer for binary expressions, it can not

4017 that did string manipulation to compute the type and then call
4018 GetType. Use Parameter.ParameterType instead.

4040 * statement.cs (Using.EmitLocalVariableDecls): Split the
4041 localvariable handling of the using statement.
4043 (Block.EmitMeta): Keep track of variable count across blocks. We
4044 were reusing slots on separate branches of blocks.
4046 (Try.Emit): Emit the general code block, we were not emitting it.
4048 Check the type of the declaration to be an IDisposable or
4049 something that can be implicity converted to it.

4072 properly generate the overflow opcodes.
4074 2001-12-04 Miguel de Icaza <miguel@ximian.com>
4076 * statement.cs: The correct type for the EmptyExpression is the
4077 element_type, not the variable type. Ravi pointed this out.
4079 2001-12-04 Ravi Pratap <ravi@ximian.com>
4081 * class.cs (Method::Define): Handle PInvoke methods specially
4082 by using DefinePInvokeMethod instead of the usual one.
4084 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
4085 above to do the task of extracting information and defining the method.
4087 2001-12-04 Ravi Pratap <ravi@ximian.com>

4174 * enum.cs (LookupEnumValue): Re-write various bits, return an object value
4175 instead of a Literal - much easier.
4177 (EnumInTransit): Remove - utterly useless :-)
4179 (Populate): Re-write bits - remove duplicate code etc. The code is much neater now.
4181 * expression.cs (MemberLookup): Cope with user-defined enums when they are in transit.

4281 (Bounds): Make it a hashtable to prevent the same dimension being
4282 recorded for every element in that dimension.

4331 2001-11-22 Miguel de Icaza <miguel@ximian.com>
4333 * statement.cs (If.Emit): Fix a bug that generated incorrect code
4334 on If. Basically, we have to return `true' (ie, we do return to

4338 short-circuit operators, handle them as short circuit operators.

4341 (Cast.Cast): Take an expression as the target type.
4343 * cs-parser.jay (cast_expression): Remove old hack that only
4344 allowed a limited set of types to be handled. Now we take a
4345 unary_expression and we resolve to a type during semantic
4348 Use the grammar productions from Rhys to handle casts (this is
4349 not complete like Rhys syntax yet, we fail to handle that corner
4350 case that C# has regarding (-x), but we will get there.
4352 2001-11-22 Ravi Pratap <ravi@ximian.com>
4354 * class.cs (EmitFieldInitializer): Take care of the case when we have a
4355 field which is an array type.

4361 (everywhere): Use the above appropriately.
4363 * cs-parser.jay (for_statement): Update for array initialization while
4364 declaring variables.
4366 * ecore.cs : The error message was correct, it's the variable's names that
4367 were misleading ;-) Make the code more readable.
4369 (MemberAccess::DoResolve): Fix the code which handles Enum literals to set
4370 the correct type etc.
4372 (ConvertExplicit): Handle Enum types by examining the underlying type.
4374 2001-11-21 Ravi Pratap <ravi@ximian.com>

4387 BindingFlags.Instance as well
4389 * ecore.cs (Expression.TryImplicitIntConversion): Wrap the result
4390 implicit int literal conversion in an empty cast so that we
4391 propagate the right type upstream.
4393 (UnboxCast): new class used to unbox value types.
4394 (Expression.ConvertExplicit): Add explicit type conversions done
4397 (Expression.ImplicitNumericConversion): Oops, forgot to test for
4398 the target type before applying the implicit LongLiterals to ULong
4401 2001-11-21 Miguel de Icaza <miguel@ximian.com>
4403 * cs-parser.jay (for_statement): Reworked the way For works: now
4404 we declare manually any variables that are introduced in
4405 for_initializer to solve the problem of having out-of-band code
4406 emition (that is what got for broken).
4408 (declaration_statement): Perform the actual variable declaration
4409 that used to be done in local_variable_declaration here.
4411 (local_variable_declaration): Do not declare anything, just pass
4412 the information on a DictionaryEntry
4414 2001-11-20 Ravi Pratap <ravi@ximian.com>
4416 * expression.cs (ArrayCreation::CheckIndices): The story continues :-) Complete

4442 (constant_declaration): Update accordingly.
4444 * expression.cs (ArrayCreation): Make ValidateInitializers simpler by factoring
4445 code into another method : UpdateIndices.
4447 2001-11-18 Ravi Pratap <ravi@ximian.com>

4479 we can use this elsewhere.
4481 * statement.cs: Finish implementation of foreach for single
4484 * cs-parser.jay: Use an out-of-band stack to pass information
4485 around, I wonder why I need this.
4487 foreach_block: Make the new foreach_block the current_block.
4489 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
4490 function used to return a static Parameters structure. Used for
4491 empty parameters, as those are created very frequently.
4493 * cs-parser.jay, class.cs: Use GetEmptyReadOnlyParameters
4495 2001-11-15 Ravi Pratap <ravi@ximian.com>
4497 * interface.cs : Default modifier is private, not public. The
4498 make verify test passes again.
4500 2001-11-15 Ravi Pratap <ravi@ximian.com>
4502 * support.cs (ReflectionParameters): Fix logic to determine
4503 whether the last parameter is a params one. Test 9 passes again.
4505 * delegate.cs (Populate): Register the builders we define with
4506 RegisterParameterForBuilder. Test 19 passes again.

4509 of $$ to get at the location.
4511 (indexer_declaration): Similar stuff.
4515 * class.cs (Property): Register parameters for the Get and Set methods

4536 2001-11-09 Miguel de Icaza <miguel@ximian.com>
4538 * enum.cs (Enum.Emit): Delay the lookup of loc until we run into
4539 an error. This removes the lookup from the critical path.

4553 and cons_param_array_attribute (ConstructorInfo for
4554 ParamArrayAttribute).,

4557 way we can report the error correctly for missing return values.
4559 * class.cs (Method.Emit): Clean up.
4561 * expression.cs (Argument.Resolve): Take another argument: the
4562 location where this argument is used. Notice that this is not
4563 part of the "Argument" class as to reduce the size of the
4564 structure (we know the approximate location anyways).
4566 Test if the argument is a variable-reference, if not, then
4567 complain with a 206.
4569 (Argument.Emit): Emit addresses of variables.
4571 (Argument.FullDesc): Simplify.
4573 (Invocation.DoResolve): Update for Argument.Resolve.
4575 (ElementAccess.DoResolve): ditto.

4598 2001-11-13 Miguel de Icaza <miguel@ximian.com>
4600 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
4601 enumerations that are used in heavily used structures derive from
4602 byte in a laughable and pathetic attempt to reduce memory usage.
4603 This is the kind of pre-optimzations that you should not do at
4604 home without adult supervision.
4606 * expression.cs (UnaryMutator): New class, used to handle ++ and
4607 -- separatedly from the other unary operators. Cleans up the
4608 code, and kills the ExpressionStatement dependency in Unary.
4610 (Unary): Removed `method' and `Arguments' from this class, making
4611 it smaller, and moving it all to SimpleCall, so I can reuse this
4612 code in other locations and avoid creating a lot of transient data
4613 strucutres when not required.
4615 * cs-parser.jay: Adjust for new changes.
4617 2001-11-11 Miguel de Icaza <miguel@ximian.com>
4619 * enum.cs (Enum.Populate): If there is a failure during
4622 * cs-parser.jay (opt_enum_base): we used to catch type errors

4628 * cs-parser.jay (operator_declarator, conversion_operator_declarator): Set

5373 Implement bits to define the Invoke method. However, I still haven't figured out
5374 how to take care of the native int bit :-(
5376 * cs-parser.jay (delegate_declaration): Fixed the bug that I had introduced :-)
5377 Qualify the name of the delegate, not its return type !
5379 * expression.cs (ImplicitReferenceConversion): Implement guts of implicit array
5382 (StandardConversionExists): Checking for array types turns out to be recursive.
5384 (ConvertReferenceExplicit): Implement array conversion.
5386 (ExplicitReferenceConversionExists): New method to determine precisely that :-)
5388 2001-10-12 Ravi Pratap <ravi@ximian.com>
5390 * cs-parser.jay (delegate_declaration): Store the fully qualified
5391 name as it is a type declaration.
5393 * delegate.cs (ReturnType, Name): Rename members to these. Make them
5396 (DefineDelegate): Renamed from Define. Does the same thing essentially,
5397 as TypeContainer::DefineType.
5399 (Populate): Method in which all the definition of the various methods (Invoke)
5402 (Emit): Emit any code, if necessary. I am not sure about this really, but let's
5405 (CloseDelegate): Finally creates the delegate.
5407 * class.cs (TypeContainer::DefineType): Update to define delegates.
5408 (Populate, Emit and CloseType): Do the same thing here too.
5410 * rootcontext.cs (ResolveTree, PopulateTypes, EmitCode, CloseTypes): Include
5411 delegates in all these operations.
5413 2001-10-14 Miguel de Icaza <miguel@ximian.com>
5415 * expression.cs: LocalTemporary: a new expression used to
5416 reference a temporary that has been created.
5418 * assign.cs: Handle PropertyAccess back here, so that we can
5419 provide the proper semantic access to properties.
5421 * expression.cs (Expression::ConvertReferenceExplicit): Implement
5422 a few more explicit conversions.
5424 * modifiers.cs: `NEW' modifier maps to HideBySig.
5426 * expression.cs (PropertyExpr): Make this into an
5427 ExpressionStatement, and support the EmitStatement code path.
5429 Perform get/set error checking, clean up the interface.
5431 * assign.cs: recognize PropertyExprs as targets, and if so, turn
5432 them into toplevel access objects.
5434 2001-10-12 Miguel de Icaza <miguel@ximian.com>
5436 * expression.cs: PropertyExpr::PropertyExpr: use work around the
5439 * typemanager.cs: Keep track here of our PropertyBuilders again to
5440 work around lameness in SRE.
5442 2001-10-11 Miguel de Icaza <miguel@ximian.com>
5444 * expression.cs (LValue::LValueResolve): New method in the
5445 interface, used to perform a second resolution pass for LValues.
5447 (This::DoResolve): Catch the use of this in static methods.
5449 (This::LValueResolve): Implement.
5451 (This::Store): Remove warning, assigning to `this' in structures
5454 (Invocation::Emit): Deal with invocation of
5455 methods on value types. We need to pass the address to structure
5456 methods rather than the object itself. (The equivalent code to
5457 emit "this" for structures leaves the entire structure on the
5458 stack instead of a pointer to it).
5460 (ParameterReference::DoResolve): Compute the real index for the
5461 argument based on whether the method takes or not a `this' pointer
5462 (ie, the method is static).
5464 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store
5465 value types returned from functions when we need to invoke a
5466 method on the sturcture.
5469 2001-10-11 Ravi Pratap <ravi@ximian.com>
5471 * class.cs (TypeContainer::DefineType): Method to actually do the business of
5472 defining the type in the Modulebuilder or Typebuilder. This is to take
5473 care of nested types which need to be defined on the TypeBuilder using
5476 (TypeContainer::GetClassBases): Implement. Essentially the code from the
5477 methods in RootContext, only ported to be part of TypeContainer.
5479 (TypeContainer::GetInterfaceOrClass): Ditto.
5481 (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
5483 * interface.cs (Interface::DefineInterface): New method. Does exactly
5484 what RootContext.CreateInterface did earlier, only it takes care of nested types
5487 (Interface::GetInterfaces): Move from RootContext here and port.
5489 (Interface::GetInterfaceByName): Same here.
5491 * rootcontext.cs (ResolveTree): Re-write.

5495 * class.cs (TypeContainer::Populate): Populate nested types too.
5496 (TypeContainer::Emit): Emit nested members too.
5498 * typemanager.cs (AddUserType): Do not make use of the FullName property,
5499 instead just use the name argument passed in as it is already fully
5502 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
5503 to TypeContainer mapping to see if a type is user-defined.
5505 * class.cs (TypeContainer::CloseType): Implement.
5507 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
5508 the default constructor.
5510 (TypeContainer::Populate): Fix minor bug which led to creating default constructors
5513 (Constructor::IsDefault): Fix up logic to determine if it is the default constructor
5515 * interface.cs (CloseType): Create the type here.
5517 * rootcontext.cs (CloseTypes): Re-write to recursively close types by running through
5520 Remove all the methods which are now in TypeContainer.
5522 2001-10-10 Ravi Pratap <ravi@ximian.com>
5524 * delegate.cs (Define): Re-write bits to define the delegate
5527 2001-10-10 Miguel de Icaza <miguel@ximian.com>
5529 * makefile: Renamed the compiler to `mcs.exe' instead of compiler.exe
5531 * expression.cs (ImplicitReferenceConversion): handle null as well
5532 as a source to convert to any reference type.
5534 * statement.cs (Return): Perform any implicit conversions to
5535 expected return type.
5537 Validate use of return statement.
5539 * codegen.cs (EmitContext): Pass the expected return type here.
5541 * class.cs (Method, Constructor, Property): Pass expected return
5542 type to EmitContext.
5544 2001-10-09 Miguel de Icaza <miguel@ximian.com>
5546 * expression.cs: Make DoResolve take an EmitContext instead of a
5549 Replaced `l' and `location' for `loc', for consistency.
5551 (Error, Warning): Remove unneeded Tc argument.
5553 * assign.cs, literal.cs, constant.cs: Update to new calling
5556 * codegen.cs: EmitContext now contains a flag indicating whether
5557 code is being generated in a static method or not.
5559 * cs-parser.jay: DecomposeQI, new function that replaces the old
5560 QualifiedIdentifier. Now we always decompose the assembled
5561 strings from qualified_identifier productions into a group of
5564 2001-10-08 Miguel de Icaza <miguel@ximian.com>
5566 * rootcontext.cs: Deal with field-less struct types correctly now
5567 by passing the size option to Define Type.
5569 * class.cs: Removed hack that created one static field.
5571 2001-10-07 Miguel de Icaza <miguel@ximian.com>
5573 * statement.cs: Moved most of the code generation here.
5575 2001-10-09 Ravi Pratap <ravi@ximian.com>
5577 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
5580 (ElementAccess): Remove useless bits for now - keep checks as the spec
5583 2001-10-08 Ravi Pratap <ravi@ximian.com>
5585 * expression.cs (ElementAccess::DoResolve): Remove my crap code
5586 and start performing checks according to the spec.
5588 2001-10-07 Ravi Pratap <ravi@ximian.com>
5590 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
5591 rank_specifiers instead.
5593 (rank_specifiers): Change the order in which the rank specifiers are stored
5595 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
5597 * expression.cs (ElementAccess): Implement the LValue interface too.
5599 2001-10-06 Ravi Pratap <ravi@ximian.com>
5601 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
5602 except that user defined conversions are not included.
5604 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
5605 perform the conversion of the return type, if necessary.
5607 (New::DoResolve): Check whether we are creating an array or an object
5608 and accordingly do the needful.
5610 (New::Emit): Same here.
5612 (New::DoResolve): Implement guts of array creation.
5614 (New::FormLookupType): Helper function.
5616 2001-10-07 Miguel de Icaza <miguel@ximian.com>
5618 * codegen.cs: Removed most of the code generation here, and move the
5619 corresponding code generation bits to the statement classes.
5621 Added support for try/catch/finalize and throw.
5623 * cs-parser.jay: Added support for try/catch/finalize.
5625 * class.cs: Catch static methods having the flags override,
5626 virtual or abstract.
5628 * expression.cs (UserCast): This user cast was not really doing
5629 what it was supposed to do. Which is to be born in fully resolved
5630 state. Parts of the resolution were being performed at Emit time!
5634 2001-10-05 Miguel de Icaza <miguel@ximian.com>
5636 * expression.cs: Implicity convert the result from UserCast.
5638 2001-10-05 Ravi Pratap <ravi@ximian.com>
5640 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
5641 prevented it from working correctly.
5643 (ConvertExplicit): Make the first try, a call to ConvertImplicitStandard, not
5644 merely ConvertImplicit.
5646 2001-10-05 Miguel de Icaza <miguel@ximian.com>
5648 * typemanager.cs: Make the LookupTypeContainer function static,
5649 and not per-instance.
5651 * class.cs: Make static FindMembers (the one that takes a Type
5654 * codegen.cs: Add EmitForeach here.
5656 * cs-parser.jay: Make foreach a toplevel object instead of the
5657 inline expansion, as we need to perform semantic analysis on it.
5659 2001-10-05 Ravi Pratap <ravi@ximian.com>
5661 * expression.cs (Expression::ImplicitUserConversion): Rename to
5662 UserDefinedConversion.
5664 (Expression::UserDefinedConversion): Take an extra argument specifying
5665 whether we look for explicit user conversions too.
5667 (Expression::ImplicitUserConversion): Make it a call to UserDefinedConversion.

5676 * expression.cs (Cast): Record location info.
5678 (Expression::ConvertExplicit): Take location argument.
5680 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
5681 to determine if we are doing explicit conversions.
5683 (UserCast::Emit): Update accordingly.
5685 (Expression::ConvertExplicit): Report an error if everything fails.
5687 * ../errors/cs0030.cs : Add.
5689 2001-10-04 Miguel de Icaza <miguel@ximian.com>
5691 * modifiers.cs: If the ABSTRACT keyword is present, also set the
5692 virtual and newslot bits.
5694 * class.cs (TypeContainer::RegisterRequiredImplementations):
5695 Record methods we need.
5697 (TypeContainer::MakeKey): Helper function to make keys for
5698 MethodBases, since the Methodbase key is useless.
5700 (TypeContainer::Populate): Call RegisterRequiredImplementations
5701 before defining the methods.
5703 Create a mapping for method_builders_to_methods ahead of time
5704 instead of inside a tight loop.
5706 (::RequireMethods): Accept an object as the data to set into the
5707 hashtable so we can report interface vs abstract method mismatch.
5709 2001-10-03 Miguel de Icaza <miguel@ximian.com>
5711 * report.cs: Make all of it static.
5713 * rootcontext.cs: Drop object_type and value_type computations, as
5714 we have those in the TypeManager anyways.
5716 Drop report instance variable too, now it is a global.
5718 * driver.cs: Use try/catch on command line handling.
5720 Add --probe option to debug the error reporting system with a test
5723 * report.cs: Add support for exiting program when a probe
5724 condition is reached.
5726 2001-10-03 Ravi Pratap <ravi@ximian.com>
5728 * expression.cs (Binary::DoNumericPromotions): Fix the case when
5729 we do a forcible conversion regardless of type, to check if
5730 ForceConversion returns a null.
5732 (Binary::error19): Use location to report error.
5734 (Unary::error23): Use location here too.
5736 * ../errors/cs0019.cs : Check in.
5738 * ../errors/cs0023.cs : Check in.
5740 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
5741 case of a non-null MethodInfo object with a length of 0 !
5743 (Binary::ResolveOperator): Flag error if overload resolution fails to find
5744 an applicable member - according to the spec :-)
5745 Also fix logic to find members in base types.
5747 (Unary::ResolveOperator): Same here.
5749 (Unary::report23): Change name to error23 and make first argument a TypeContainer
5750 as I was getting thoroughly confused between this and error19 :-)
5752 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
5753 (::FindMostEncompassedType): Implement.
5754 (::FindMostEncompassingType): Implement.
5755 (::StandardConversionExists): Implement.
5757 (UserImplicitCast): Re-vamp. We now need info about most specific
5758 source and target types so that we can do the necessary conversions.
5760 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
5761 mathematical union with no duplicates.
5763 2001-10-03 Miguel de Icaza <miguel@ximian.com>
5765 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
5766 in order from base classes to child classes, so that we can in
5767 child classes look up in our parent for method names and
5768 attributes (required for handling abstract, virtual, new, override
5769 constructs: we need to instrospect our base class, and if we dont
5770 populate the classes in order, the introspection might be
5771 incorrect. For example, a method could query its parent before
5772 the parent has any methods and would determine that the parent has
5773 no abstract methods (while it could have had them)).
5775 (RootContext::CreateType): Record the order in which we define the
5778 2001-10-02 Miguel de Icaza <miguel@ximian.com>
5780 * class.cs (TypeContainer::Populate): Also method definitions can
5781 fail now, keep track of this.
5783 (TypeContainer::FindMembers): Implement support for
5784 DeclaredOnly/noDeclaredOnly flag.
5786 (Constructor::Emit) Return the ConstructorBuilder.
5788 (Method::Emit) Return the MethodBuilder.
5789 Check for abstract or virtual methods to be public.
5791 * rootcontext.cs (RootContext::CreateType): Register all the
5792 abstract methods required for the class to be complete and the
5793 interface methods that must be implemented.
5795 * cs-parser.jay: Report error 501 (method requires body if it is
5796 not marked abstract or extern).
5798 * expression.cs (TypeOf::Emit): Implement.
5800 * typemanager.cs: runtime_handle_type, new global type.
5802 * class.cs (Property::Emit): Generate code for properties.
5804 2001-10-02 Ravi Pratap <ravi@ximian.com>
5806 * expression.cs (Unary::ResolveOperator): Find operators on base type
5807 too - we now conform exactly to the spec.
5809 (Binary::ResolveOperator): Same here.
5811 * class.cs (Operator::Define): Fix minor quirk in the tests.
5813 * ../errors/cs0215.cs : Added.
5815 * ../errors/cs0556.cs : Added.
5817 * ../errors/cs0555.cs : Added.
5819 2001-10-01 Miguel de Icaza <miguel@ximian.com>
5821 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
5822 single integer which is really efficient
5824 2001-10-01 Ravi Pratap <ravi@ximian.com>
5826 * expression.cs (Expression::ImplicitUserConversion): Use location
5827 even in the case when we are examining True operators.
5829 * class.cs (Operator::Define): Perform extensive checks to conform
5830 with the rules for operator overloading in the spec.
5832 * expression.cs (Expression::ImplicitReferenceConversion): Implement
5833 some of the other conversions mentioned in the spec.
5835 * typemanager.cs (array_type): New static member for the System.Array built-in
5838 (cloneable_interface): For System.ICloneable interface.
5840 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
5841 we start resolving the tree and populating types.
5843 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
5845 2001-10-01 Miguel de Icaza <miguel@ximian.com>
5847 * expression.cs (Expression::ExprClassFromMemberInfo,
5848 Expression::Literalize): Create literal expressions from
5849 FieldInfos which are literals.
5851 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
5852 type casts, because they were wrong. The test suite in tests
5855 (ImplicitNumericConversion): ushort to ulong requires a widening
5858 Int32 constant to long requires widening cast as well.
5860 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
5861 for integers because the type on the stack is not i4.
5863 2001-09-30 Miguel de Icaza <miguel@ximian.com>
5865 * expression.cs (report118): require location argument.
5867 * parameter.cs: Do not dereference potential null value.
5869 * class.cs: Catch methods that lack the `new' keyword when
5870 overriding a name. Report warnings when `new' is used without
5871 anything being there to override.
5873 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
5875 * class.cs: Only add constructor to hashtable if it is non-null
5876 (as now constructors can fail on define).
5878 (TypeManager, Class, Struct): Take location arguments.
5880 Catch field instance initialization in structs as errors.
5882 accepting_filter: a new filter for FindMembers that is static so
5883 that we dont create an instance per invocation.
5885 (Constructor::Define): Catch errors where a struct constructor is
5888 * cs-parser.jay: Pass location information for various new
5891 * delegate.cs (Delegate): take a location argument.
5893 * driver.cs: Do not call EmitCode if there were problesm in the
5894 Definition of the types, as many Builders wont be there.
5896 * decl.cs (Decl::Decl): Require a location argument.
5898 * cs-tokenizer.cs: Handle properly hex constants that can not fit
5899 into integers, and find the most appropiate integer for it.
5901 * literal.cs: Implement ULongLiteral.
5903 * rootcontext.cs: Provide better information about the location of
5904 failure when CreateType fails.
5906 2001-09-29 Miguel de Icaza <miguel@ximian.com>
5908 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
5911 * expression.cs (Binary::CheckShiftArguments): Add missing type
5913 (Binary::ResolveOperator): Add type to the logical and and logical
5914 or, Bitwise And/Or and Exclusive Or code paths, it was missing
5917 (Binary::DoNumericPromotions): In the case where either argument
5918 is ulong (and most signed types combined with ulong cause an
5919 error) perform implicit integer constant conversions as well.
5921 2001-09-28 Miguel de Icaza <miguel@ximian.com>
5923 * expression.cs (UserImplicitCast): Method should always be
5925 (Invocation::BetterConversion): Simplified test for IntLiteral.
5927 (Expression::ImplicitNumericConversion): Split this routine out.
5928 Put the code that performs implicit constant integer conversions
5931 (Expression::Resolve): Become a wrapper around DoResolve so we can
5932 check eclass and type being set after resolve.
5934 (Invocation::Badness): Remove this dead function
5936 (Binary::ResolveOperator): Do not compute the expensive argumnets
5937 unless we have a union for it.
5939 (Probe::Emit): Is needs to do an isinst and then
5940 compare against null.
5942 (::CanConvert): Added Location argument. If the Location argument
5943 is null (Location.Null), then we do not report errors. This is
5944 used by the `probe' mechanism of the Explicit conversion. We do
5945 not want to generate an error for something that the user
5946 explicitly requested to be casted. But the pipeline for an
5947 explicit cast first tests for potential implicit casts.
5949 So for now, if the Location is null, it means `Probe only' to
5950 avoid adding another argument. Might have to revise this
5953 (ClassCast): New class used to type cast objects into arbitrary
5954 classes (used in Explicit Reference Conversions).
5956 Implement `as' as well.
5958 Reverted all the patches from Ravi below: they were broken:
5960 * The use of `level' as a mechanism to stop recursive
5961 invocations is wrong. That was there just to catch the
5962 bug with a strack trace but not as a way of addressing
5965 To fix the problem we have to *understand* what is going
5966 on and the interactions and come up with a plan, not
5967 just get things going.
5969 * The use of the type conversion cache that I proposed
5970 last night had an open topic: How does this work across
5971 protection domains. A user defined conversion might not
5972 be public in the location where we are applying the
5973 conversion, a different conversion might be selected
5974 (ie, private A->B (better) but public B->A (worse),
5975 inside A, A->B applies, but outside it, B->A will
5978 * On top of that (ie, even if the above is solved),
5979 conversions in a cache need to be abstract. Ie, `To
5980 convert from an Int to a Short use an OpcodeCast', not
5981 `To convert from an Int to a Short use the OpcodeCast on
5982 the variable 5' (which is what this patch was doing).
5984 2001-09-28 Ravi Pratap <ravi@ximian.com>
5986 * expression.cs (Invocation::ConversionExists): Re-write to use
5987 the conversion cache
5989 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
5990 cache all conversions done, not just user-defined ones.
5992 (Invocation::BetterConversion): The real culprit. Use ConversionExists
5993 to determine if a conversion exists instead of acutually trying to
5994 perform the conversion. It's faster too.
5996 (Expression::ConvertExplicit): Modify to use ConversionExists to check
5997 and only then attempt the implicit conversion.
5999 2001-09-28 Ravi Pratap <ravi@ximian.com>
6001 * expression.cs (ConvertImplicit): Use a cache for conversions
6002 already found. Check level of recursion and bail out if necessary.
6004 2001-09-28 Miguel de Icaza <miguel@ximian.com>
6006 * typemanager.cs (string_concat_string_string, string_concat_object_object):
6007 Export standard methods that we expect for string operations.
6009 * statement.cs (Block::UsageWarning): Track usage of variables and
6010 report the errors for not used variables.
6012 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
6015 2001-09-27 Miguel de Icaza <miguel@ximian.com>
6017 * codegen.cs: remove unnneded code
6019 * expression.cs: Removed BuiltinTypeAccess class
6021 Fix the order in which implicit conversions are
6024 The previous fixed dropped support for boxed conversions (adding a
6025 test to the test suite now)
6027 (UserImplicitCast::CanConvert): Remove test for source being null,
6028 that code is broken. We should not feed a null to begin with, if
6029 we do, then we should track the bug where the problem originates
6030 and not try to cover it up here.
6032 Return a resolved expression of type UserImplicitCast on success
6033 rather than true/false. Ravi: this is what I was talking about,
6034 the pattern is to use a static method as a "constructor" for
6037 Also, do not create arguments until the very last minute,
6038 otherwise we always create the arguments even for lookups that
6039 will never be performed.
6041 (UserImplicitCast::Resolve): Eliminate, objects of type
6042 UserImplicitCast are born in a fully resolved state.
6044 * typemanager.cs (InitCoreTypes): Init also value_type
6047 * expression.cs (Cast::Resolve): First resolve the child expression.
6049 (LValue): Add new method AddressOf to be used by
6052 Change the argument of Store to take an EmitContext instead of an
6053 ILGenerator, because things like FieldExpr need to be able to call
6054 their children expression to generate the instance code.
6056 (Expression::Error, Expression::Warning): Sugar functions for
6059 (Expression::MemberLookup): Accept a TypeContainer instead of a
6060 Report as the first argument.
6062 (Expression::ResolvePrimary): Killed. I still want to improve
6063 this as currently the code is just not right.
6065 (Expression::ResolveMemberAccess): Simplify, but it is still
6068 (Unary::Resolve): Catch errors in AddressOf operators.
6070 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
6071 index to a byte for the short-version, or the compiler will choose
6072 the wrong Emit call, which generates the wrong data.

6076 (FieldExpr::AddressOf): Implement.
6078 * typemanager.cs: TypeManager: made public variable instead of
6081 * driver.cs: document --fatal.

6084 Error and Warning classes.
6086 * cs-parser.jay (member_access): Turn built-in access to types
6087 into a normal simplename
6089 2001-09-27 Ravi Pratap <ravi@ximian.com>

6092 with q being null, since this was introducing a bug.
6094 * expression.cs (ConvertImplicit): Do built-in conversions first.
6096 2001-09-27 Ravi Pratap <ravi@ximian.com>
6098 * expression.cs (UserImplicitCast::Resolve): Fix bug.
6100 2001-09-27 Ravi Pratap <ravi@ximian.com>
6102 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug

6105 * expression.cs (UserImplicitCast::CanConvert): Static method to do
6106 the work of all the checking.
6107 (ConvertImplicit): Call CanConvert and only then create object if necessary.
6108 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
6110 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
6111 that is the right way.
6113 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
6114 overloading resolution. Use everywhere instead of cutting and pasting code.
6116 (Binary::ResolveOperator): Use MakeUnionSet.
6118 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
6119 we have to convert to bool types. Not complete yet.
6121 2001-09-27 Miguel de Icaza <miguel@ximian.com>
6123 * typemanager.cs (TypeManager::CSharpName): support ushort.
6125 * expression.cs (Expression::TryImplicitIntConversion): Attempts
6126 to provide an expression that performsn an implicit constant int
6127 conversion (section 6.1.6).
6128 (Expression::ConvertImplicitRequired): Reworked to include
6129 implicit constant expression conversions.
6131 (Expression::ConvertNumericExplicit): Finished.
6133 (Invocation::Emit): If InstanceExpression is null, then it means
6134 that we perform a call on this.
6136 2001-09-26 Miguel de Icaza <miguel@ximian.com>
6138 * expression.cs (Unary::Emit): Remove some dead code.
6139 (Probe): Implement Resolve and Emit for `is'.
6140 (Expression::ConvertImplicitRequired): Attempt to do constant
6141 expression conversions here. Maybe should be moved to
6142 ConvertImplicit, but I am not sure.
6143 (Expression::ImplicitLongConstantConversionPossible,
6144 Expression::ImplicitIntConstantConversionPossible): New functions
6145 that tell whether is it possible to apply an implicit constant
6146 expression conversion.

6159 ones that the spec expects (as we are just stringizing the
6162 * expression.cs (Unary::ResolveOperator): Fix bug: Use
6163 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
6164 previous usage did only work for our methods.
6165 (Expression::ConvertImplicit): Handle decimal implicit numeric
6166 conversions as well.
6167 (Expression::InternalTypeConstructor): Used to invoke constructors
6168 on internal types for default promotions.
6170 (Unary::Emit): Implement special handling for the pre/post
6171 increment/decrement for overloaded operators, as they need to have
6172 the same semantics as the other operators.
6174 (Binary::ResolveOperator): ditto.
6175 (Invocation::ConversionExists): ditto.
6176 (UserImplicitCast::Resolve): ditto.
6178 2001-09-26 Ravi Pratap <ravi@ximian.com>
6180 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded

6195 expressions that can appear in statements, so that we can provide
6196 an alternate path to generate expression that do not leave a value
6199 (Expression::Emit, and all the derivatives): We no longer return
6200 whether a value is left on the stack or not. Every expression
6201 after being emitted leaves a single value on the stack.
6203 * codegen.cs (EmitContext::EmitStatementExpression): Use the
6204 facilties of ExpressionStatement if possible.
6206 * cs-parser.jay: Update statement_expression.

6227 (ConvertImplicit): Do user-defined conversion if it exists.
6229 2001-09-24 Miguel de Icaza <miguel@ximian.com>
6231 * assign.cs: track location.
6232 (Resolve): Use implicit conversions on assignment.

6275 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
6276 Also take an additional TypeContainer argument.
6278 * All over : Pass in TypeContainer as argument to OverloadResolve.
6280 * typemanager.cs (CSharpName): Update to check for the string type and return

6297 * typemanager.cs: declare and load enum_type, delegate_type and
6300 * expression.cs (Expression::Emit): Now emit returns a value that
6301 tells whether a value is left on the stack or not. This strategy
6302 might be reveted tomorrow with a mechanism that would address
6303 multiple assignments.
6304 (Expression::report118): Utility routine to report mismatches on
6307 (Unary::Report23): Report impossible type/operator combination
6310 (Unary::IsIncrementableNumber): Whether the type can be

6355 * expression.cs: Instead of having FIXMEs in the Resolve
6356 functions, throw exceptions so it is obvious that we are facing a
6359 * cs-parser.jay (invocation_expression): Pass Location information.
6361 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
6362 Use a basename for those routines because .NET does not like paths

6374 * expression.cs (Unary::ResolveOperator): return the child
6375 expression for expressions which are just +expr.
6376 (Unary::ResolveOperator): Return negative literals for -LITERAL
6377 expressions (otherwise they are Unary {Literal}).
6378 (Invocation::Badness): Take into account `Implicit constant
6379 expression conversions'.
6381 * literal.cs (LongLiteral): Implement long literal class.
6382 (IntLiteral): export the `Value' of the intliteral.
6384 2001-09-19 Ravi Pratap <ravi@ximian.com>
6386 * expression.cs (Binary::Emit): Finally get the emission right ! Woo!
6388 * class.cs (Operator::Define): Change the methodname prefix to 'op_'
6389 instead of 'Operator'
6391 * expression.cs (Binary::ResolveOperator): Update accordingly.
6392 (Unary::Operator): Change names to 'Add' and 'Subtract' instead 'Plus'

6399 * expression.cs (Unary::Resolve): Implement.
6400 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
6401 operators are found instead of making noise ;-)
6402 (Unary::ResolveOperator): New method to do precisely the same thing which
6403 Binary::ResolveOperator does for Binary expressions.
6404 (Unary.method, .Arguments): Add.
6405 (Unary::OperName): Implement.
6406 (Unary::ForceConversion): Copy and Paste !
6408 * class.cs (Operator::Define): Fix a small bug for the case when we have
6411 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
6412 for the inbuilt operators. Only overloading works for now ;-)
6414 2001-09-18 Miguel de Icaza <miguel@ximian.com>
6416 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
6417 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

6430 (FieldExpr::Emit): Implement.
6432 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
6433 the last instruction contains a return opcode to avoid generating
6434 the last `ret' instruction (this generates correct code, and it is
6435 nice to pass the peverify output).
6437 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
6438 initializer for static and instance variables.
6439 (Constructor::Emit): Allow initializer to be null in the case of
6440 static constructors. Only emit initializer for instance
6443 (TypeContainer::FindMembers): Return a null array if there are no
6446 Also fix the code for the MemberTypes.Method branch, as it was not
6447 scanning that for operators (or tried to access null variables before).
6449 * assign.cs (Assign::Emit): Handle instance and static fields.
6453 * driver.cs: Stop compilation if there are parse errors.
6455 * cs-parser.jay (constructor_declaration): Provide default base
6456 initializer for non-static constructors.

6458 initializers if none was specified.
6459 Catch the fact that constructors should not have parameters.
6461 * class.cs: Do not emit parent class initializers for static
6462 constructors, that should be flagged as an error.
6464 2001-09-18 Ravi Pratap <ravi@ximian.com>
6466 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
6467 Move back code into TypeContainer::Populate.

6493 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
6496 (Expression::MemberLookup): Provide a version that allows to
6497 specify the MemberTypes and BindingFlags.
6499 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
6500 so it was not fetching variable information from outer blocks.
6502 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
6503 Beforefieldinit as it was buggy.
6505 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
6508 * class.cs (Constructor::Emit): Only emit if block is not null.
6509 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
6510 deal with this by semantically definining it as if the user had
6513 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
6514 constructors as we now "emit" them at a higher level.
6516 (TypeContainer::DefineDefaultConstructor): Used to define the
6517 default constructors if none was provided.
6519 (ConstructorInitializer): Add methods Resolve and Emit.
6521 * expression.cs: Cast to ConstructorInfo instead of MethodInfo

6540 * class.cs (Operator::OpType): Change names to match the ones in Binary::Operator
6541 and Unary::Operator.
6543 * cs-parser.jay (operator_declaration, CheckBinaryOperator, CheckUnaryOperator): Update
6546 * expression.cs (Binary::method): New member to hold the MethodBase for the case when
6547 we have overloaded operators.
6548 (Binary::ResolveOperator): Implement the part which does the operator overload
6551 * class.cs (Operator::Emit): Implement.
6552 (TypeContainer::Emit): Emit the operators we have too.
6554 * expression.cs (Binary::Emit): Update to emit the appropriate code for
6555 the case when we have a user-defined operator.
6557 2001-09-17 Miguel de Icaza <miguel@ximian.com>
6559 * rootcontext.cs: Fix bug: tree.Namespaces might be null.
6561 2001-09-16 Ravi Pratap <ravi@ximian.com>
6563 * class.cs (EmitStaticFieldInitializers, EmitFieldInitializers): Make public.
6564 (TypeContainer::EmitConstructor): Remove and move code into Contructor::Emit.

6587 * rootcontext.cs (IsNamespace): Fixed it :-)
6589 2001-09-14 Miguel de Icaza <miguel@ximian.com>
6591 * class.cs (TypeContainer::FindMembers): Add support for
6593 (MethodCore): New class that encapsulates both the shared aspects
6594 of a Constructor and a Method.

6598 Load System assembly as well as part of the standard library.
6600 * report.cs: Allow throwing exceptions on errors for debugging.
6602 * modifiers.cs: Do not use `parent', instead use the real type
6603 container to evaluate permission settings.
6605 * class.cs: Put Ravi's patch back in. He is right, and we will
6606 have to cope with the
6608 2001-09-14 Ravi Pratap <ravi@ximian.com>
6610 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
6611 FamORAssem, not FamANDAssem.

6615 * driver.cs: Added --parse option that only parses its input files
6618 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
6619 incorrect. IsTopLevel is not used to tell whether an object is
6620 root_types or not (that can be achieved by testing this ==
6621 root_types). But to see if this is a top-level *class* (not
6622 necessarly our "toplevel" container).
6624 2001-09-14 Ravi Pratap <ravi@ximian.com>
6626 * enum.cs (Enum::Define): Modify to call the Lookup method on the
6627 parent instead of a direct call to GetType.
6629 2001-09-14 Ravi Pratap <ravi@ximian.com>
6631 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
6632 Modifiers.TypeAttr. This should just be a call to that method.
6634 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
6635 object so that we can determine if we are top-level or not.
6637 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
6640 * enum.cs (Enum::Define): Ditto.
6642 * modifiers.cs (FieldAttr): Re-write.
6644 * class.cs (TypeContainer::IsTopLevel): Change accessibility to public.
6645 (TypeContainer::HaveStaticConstructor): New property to provide access
6646 to precisely that info.
6648 * modifiers.cs (MethodAttr): Re-write.
6649 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
6651 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
6652 of top-level types as claimed.
6654 2001-09-13 Miguel de Icaza <miguel@ximian.com>
6656 * expression.cs (MemberLookup): Fruitless attempt to lookup
6657 constructors. Maybe I need to emit default constructors? That
6658 might be it (currently .NET emits this for me automatically).
6659 (Invocation::OverloadResolve): Cope with Arguments == null.
6660 (Invocation::EmitArguments): new function, shared by the new
6662 (Invocation::Emit): Handle static and instance methods. Emit
6663 proper call instruction for virtual or non-virtual invocations.
6664 (New::Emit): Implement.
6665 (New::Resolve): Implement.
6666 (MemberAccess:Resolve): Implement.

6669 (FieldExpr::Resolve): Set type.
6671 * support.cs: Handle empty arguments.

6674 SimpleLookup): Auxiliary routines to help parse a qualifier
6677 Update qualifier_identifier rule.
6679 * codegen.cs: Removed debugging messages.
6681 * class.cs: Make this a global thing, this acts just as a "key" to
6682 objects that we might have around.
6684 (Populate): Only initialize method_builders_to_methods once.
6686 * expression.cs (PropertyExpr): Initialize type from the
6689 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
6690 Resolve pattern. Attempt to implicitly convert value to boolean.
6693 * expression.cs: Set the type for the int32/int32 argument case.
6694 (Binary::ResolveOperator): Set the return type to boolean for
6695 comparission operators
6697 * typemanager.cs: Remove debugging print code.
6699 (Invocation::Resolve): resolve type.
6701 * class.cs: Allocate a MemberInfo of the correct size, as the code
6702 elsewhere depends on the test to reflect the correct contents.
6704 (Method::) Keep track of parameters, due to System.Reflection holes
6706 (TypeContainer::Populate): Keep track of MethodBuilders to Method
6709 (TypeContainer::FindMembers): Use ArrayList and then copy an array
6710 of the exact size and return that.
6712 (Class::LookupMethodByBuilder): New function that maps
6713 MethodBuilders to its methods. Required to locate the information
6714 on methods because System.Reflection bit us again.
6716 * support.cs: New file, contains an interface ParameterData and
6717 two implementations: ReflectionParameters and InternalParameters

7034 will is used during the tree rewriting as we resolve them during

7161 * class.cs (Property): Revamp to use the convention of making fields readonly.

7210 and re-write the code in the actions to extract the specific and
7211 general catch clauses by being a little smart ;-)
7213 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
7214 Hooray, try and catch statements parse fine !
7216 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
7218 * statement.cs (Block::GetVariableType): Fix logic to extract the type
7219 string from the hashtable of variables.

7272 instead of ignoring the rank_specifiers.
7273 (expression_list): Implement to collect the expressions

7277 (array_initializer): Make it a list of variable_initializers
7278 (opt_array_initializer): Modify accordingly.
7280 * expression.cs (New::NType): Add enumeration to help us

7300 types after we have populated the type manager with the user

7309 generation from working. Also add some temporary debugging
7312 2001-08-24 Miguel de Icaza <miguel@ximian.com>

7315 beginning, will continue tomorrow with more touches of polish. We

7319 * gen-treedump.cs: Bug fix, use s.Increment here instead of
7322 * codegen.cs (EmitContext): New struct, used during code
7323 emission to keep a context. Most of the code generation will be
7326 * cs-parser.jay: Add embedded blocks to the list of statements of
7327 this block. So code generation proceeds in a top down fashion.
7329 2001-08-23 Miguel de Icaza <miguel@ximian.com>
7331 * statement.cs: Add support for multiple child blocks.
7333 2001-08-22 Miguel de Icaza <miguel@ximian.com>

7336 Block of code given a TypeContainer and its ILGenerator.
7338 * statement.cs (Block): Standard public readonly optimization.
7339 (Block::Block constructors): Link children.
7340 (Block::Child): Child Linker.
7341 (Block::EmitVariables): Emits IL variable declarations.
7343 * class.cs: Drop support for MethodGroups here, delay until
7345 (Method::): Applied the same simplification that I did before, and
7346 move from Properties to public readonly fields.
7347 (Method::ParameterTypes): Returns the parameter types for the
7348 function, and implements a cache that will be useful later when I
7349 do error checking and the semantic analysis on the methods is
7351 (Constructor::GetCallingConvention): Renamed from CallingConvetion
7352 and made a method, optional argument tells whether this is a class
7353 or a structure to apply the `has-this' bit.
7354 (Method::GetCallingConvention): Implement, returns the calling
7356 (Method::Define): Defines the type, a second pass is performed
7357 later to populate the methods.
7359 (Constructor::ParameterTypes): implement a cache similar to the
7360 one on Method::ParameterTypes, useful later when we do semantic
7363 (TypeContainer::EmitMethod): New method. Emits methods.
7365 * expression.cs: Removed MethodGroup class from here.
7367 * parameter.cs (Parameters::GetCallingConvention): new method.

7375 (Constructor::ParameterTypes): Returns the constructor parameter
7378 (TypeContainer::AddConstructor): Keep track of default constructor
7379 and the default static constructor.
7381 (Constructor::) Another class that starts using `public readonly'
7382 instead of properties.
7384 (Constructor::IsDefault): Whether this is a default constructor.
7386 (Field::) use readonly public fields instead of properties also.
7388 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
7389 track of static constructors; If none is used, turn on
7390 BeforeFieldInit in the TypeAttributes.
7392 * cs-parser.jay (opt_argument_list): now the return can be null
7393 for the cases where there are no arguments.
7395 (constructor_declarator): If there is no implicit `base' or
7396 `this', then invoke the default parent constructor.
7398 * modifiers.cs (MethodAttr): New static function maps a set of
7399 modifiers flags into a MethodAttributes enum
7400 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
7401 MethodAttr, TypeAttr to represent the various mappings where the
7403 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
7405 2001-08-19 Miguel de Icaza <miguel@ximian.com>
7407 * parameter.cs (GetParameterInfo): Fix bug where there would be no
7410 * interface.cs (PopulateIndexer): Implemented the code generator
7411 for interface indexers.
7413 2001-08-17 Miguel de Icaza <miguel@ximian.com>
7415 * interface.cs (InterfaceMemberBase): Now we track the new status
7418 (PopulateProperty): Implement property population. Woohoo! Got
7419 Methods and Properties going today.
7421 Removed all the properties for interfaces, and replaced them with
7422 `public readonly' fields.
7424 2001-08-16 Miguel de Icaza <miguel@ximian.com>
7426 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
7427 initialize their hashtables/arraylists only when they are needed
7428 instead of doing this always.
7430 * parameter.cs: Handle refs and out parameters.
7432 * cs-parser.jay: Use an ArrayList to construct the arguments
7433 instead of the ParameterCollection, and then cast that to a
7436 * parameter.cs: Drop the use of ParameterCollection and use
7437 instead arrays of Parameters.
7439 (GetParameterInfo): Use the Type, not the Name when resolving
7442 2001-08-13 Miguel de Icaza <miguel@ximian.com>
7444 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
7445 and instead use public readonly fields.
7447 * class.cs: Put back walking code for type containers.
7449 2001-08-11 Miguel de Icaza <miguel@ximian.com>
7451 * class.cs (MakeConstant): Code to define constants.
7453 * rootcontext.cs (LookupType): New function. Used to locate types
7456 2001-08-08 Miguel de Icaza <miguel@ximian.com>
7458 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
7459 this System.Reflection code is. Kudos to Microsoft
7461 * typemanager.cs: Implement a type cache and avoid loading all
7462 types at boot time. Wrap in LookupType the internals. This made
7463 the compiler so much faster. Wow. I rule!
7465 * driver.cs: Make sure we always load mscorlib first (for
7466 debugging purposes, nothing really important).
7468 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
7469 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
7471 * rootcontext.cs: Lookup types on their namespace; Lookup types
7472 on namespaces that have been imported using the `using' keyword.
7474 * class.cs (TypeContainer::TypeAttr): Virtualize.
7475 (Class::TypeAttr): Return attributes suitable for this bad boy.
7476 (Struct::TypeAttr): ditto.
7477 Handle nested classes.
7478 (TypeContainer::) Remove all the type visiting code, it is now
7479 replaced with the rootcontext.cs code
7481 * rootcontext.cs (GetClassBases): Added support for structs.
7483 2001-08-06 Miguel de Icaza <miguel@ximian.com>
7485 * interface.cs, statement.cs, class.cs, parameter.cs,
7486 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
7487 Drop use of TypeRefs, and use strings instead.
7489 2001-08-04 Miguel de Icaza <miguel@ximian.com>
7493 * class.cs (Struct::Struct): set the SEALED flags after
7494 checking the modifiers.
7495 (TypeContainer::TypeAttr): new property, returns the
7496 TypeAttributes for a class.
7498 * cs-parser.jay (type_list): Oops, list production was creating a
7499 new list of base types.
7501 * rootcontext.cs (StdLib): New property.
7502 (GetInterfaceTypeByName): returns an interface by type name, and
7503 encapsulates error handling here.
7504 (GetInterfaces): simplified.
7505 (ResolveTree): Encapsulated all the tree resolution here.
7506 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
7509 * driver.cs: Add support for --nostdlib, to avoid loading the
7511 (Main): Do not put tree resolution here.
7513 * rootcontext.cs: Beginning of the class resolution.
7515 2001-08-03 Miguel de Icaza <miguel@ximian.com>
7517 * rootcontext.cs: Provide better error reporting.
7519 * cs-parser.jay (interface_base): set our $$ to be interfaces.
7521 * rootcontext.cs (CreateInterface): Handle the case where there
7522 are no parent interfaces.
7524 (CloseTypes): Routine to flush types at the end.
7525 (CreateInterface): Track types.
7526 (GetInterfaces): Returns an array of Types from the list of
7529 * typemanager.c (AddUserType): Mechanism to track user types (puts
7530 the type on the global type hash, and allows us to close it at the
7533 2001-08-02 Miguel de Icaza <miguel@ximian.com>
7535 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
7536 RecordInterface instead.
7538 * cs-parser.jay: Updated to reflect changes above.
7540 * decl.cs (Definition): Keep track of the TypeBuilder type that
7541 represents this type here. Not sure we will use it in the long
7542 run, but wont hurt for now.
7544 * driver.cs: Smaller changes to accomodate the new code.
7546 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
7549 * rootcontext.cs (CreateInterface): New method, used to create
7550 the System.TypeBuilder type for interfaces.
7551 (ResolveInterfaces): new entry point to resolve the interface
7553 (CodeGen): Property, used to keep track of the code generator.
7555 2001-07-26 Miguel de Icaza <miguel@ximian.com>
7557 * cs-parser.jay: Add a second production for delegate_declaration
7560 (enum_body): Put an opt_comma here instead of putting it on
7561 enum_body or enum_member_declarations so we can handle trailing
7562 commas on enumeration members. Gets rid of a shift/reduce.
7564 (type_list): Need a COMMA in the middle.
7566 (indexer_declaration): Tell tokenizer to recognize get/set
7568 * Remove old targets.
7570 * Re-add the parser target.
7572 2001-07-13 Simon Cozens <simon@simon-cozens.org>
7574 * cs-parser.jay: Add precendence rules for a number of operators
7575 ot reduce the number of shift/reduce conflicts in the grammar.
7577 2001-07-17 Miguel de Icaza <miguel@ximian.com>
7579 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
7582 Get rid of old crufty code.
7584 * rootcontext.cs: Use this to keep track of the parsed
7585 representation and the defined types available to the program.
7587 * gen-treedump.cs: adjust for new convention.
7589 * type.cs: Split out the type manager, and the assembly builder
7592 * typemanager.cs: the type manager will live here now.
7594 * cil-codegen.cs: And the code generator here.
7596 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
7598 * makefile: Fixed up for easy making.
7600 2001-07-13 Simon Cozens <simon@simon-cozens.org>
7602 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
7605 (unary_expression): Expand pre_increment_expression and
7606 post_decrement_expression to reduce a shift/reduce.
7608 2001-07-11 Simon Cozens
7610 * cs-tokenizer.cs: Hex numbers should begin with a 0.
7612 Improve allow_keyword_as_indent name.
7614 2001-06-19 Miguel de Icaza <miguel@ximian.com>
7616 * Adjustments for Beta2.
7618 2001-06-13 Miguel de Icaza <miguel@ximian.com>
7620 * decl.cs: Added `Define' abstract method.
7621 (InTransit): new property, used to catch recursive definitions.
7623 * interface.cs: Implement `Define'.
7625 * modifiers.cs: Map Modifiers.constants to
7626 System.Reflection.TypeAttribute flags.
7628 * class.cs: Keep track of types and user-defined types.
7629 (BuilderInit): New method for creating an assembly
7630 (ResolveType): New function to launch the resolution process, only
7631 used by interfaces for now.
7633 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
7634 that are inserted into the name space.
7636 2001-06-08 Miguel de Icaza <miguel@ximian.com>
7638 * ARGH. I have screwed up my tree so many times due to the use of
7639 rsync rather than using CVS. Going to fix this at once.
7641 * driver.cs: Objetify driver. Load assemblies, use assemblies to
7644 2001-06-07 Miguel de Icaza <miguel@ximian.com>
7646 * Experiment successful: Use System.Type rather that our own
7649 2001-05-25 Miguel de Icaza <miguel@ximian.com>
7651 * cs-parser.jay: Removed nsAliases from here.
7653 Use new namespaces, handle `using XXX;'
7655 * namespace.cs: Reimplemented namespace handling, use a recursive
7656 definition of the class. Now we can keep track of using clauses
7657 and catch invalid using clauses.
7659 2001-05-24 Miguel de Icaza <miguel@ximian.com>
7661 * gen-treedump.cs: Adapted for all the renaming.
7663 * expression.cs (Expression): this class now has a Type property
7664 which returns an expression Type.
7666 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
7667 `Type', as this has a different meaning now in the base
7669 2001-05-22 Miguel de Icaza <miguel@ximian.com>
7671 * interface.cs, class.cs: Removed from all the sources the
7672 references to signature computation, as we can not do method
7673 signature computation during the parsing time, as we are not
7674 trying to solve at that point distinguishing:
7678 void a (NS.Blah x) {}
7681 Which depending on the context might be valid or not, as we do not
7682 know if Blah is the same thing as NS.Blah at that point.
7684 * Redid everything so the code uses TypeRefs now instead of
7685 Types. TypeRefs are just temporary type placeholders, that need
7686 to be resolved. They initially have a pointer to a string and the
7687 current scope in which they are used. This is used later by the
7688 compiler to resolve the reference to an actual Type.
7690 * DeclSpace is no longer a CIR.Type, and neither are
7691 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
7692 are all DeclSpaces, but no Types.
7694 * type.cs (TypeRefManager): This implements the TypeRef manager,
7695 which keeps track of all the types that need to be resolved after
7696 the parsing has finished.
7698 2001-05-13 Miguel de Icaza <miguel@ximian.com>
7700 * ARGH. We are going to have to store `foreach' as a class rather
7701 than resolving it, as we need to verify error 1579 after name
7702 resolution. *OR* we could keep a flag that says `This request to
7703 IEnumerator comes from a foreach statement' which we can then use
7704 to generate the error.
7706 2001-05-10 Miguel de Icaza <miguel@ximian.com>
7708 * class.cs (TypeContainer.AddMethod): we now add methods to the
7709 MethodGroup instead of the method hashtable.
7711 * expression.cs: Add MethodGroup abstraction, which gets us one
7712 step closer to the specification in the way we handle method
7715 * cs-parser.jay (primary_expression): qualified_identifier now
7716 tried to match up an identifier to a local variable reference or
7717 to a parameter reference.
7719 current_local_parameters is now a parser global variable that
7720 points to the current parameters for the block, used during name
7723 (property_declaration): Now creates an implicit `value' argument to
7726 2001-05-09 Miguel de Icaza <miguel@ximian.com>
7728 * parameter.cs: Do not use `param' arguments as part of the
7729 signature, per the spec.
7731 2001-05-08 Miguel de Icaza <miguel@ximian.com>
7733 * decl.cs: Base class for classes, structs and interfaces. This
7734 is the "Declaration Space"
7736 * cs-parser.jay: Use CheckDef for checking declaration errors
7737 instead of having one on each function.
7739 * class.cs: Factor out some code for handling error handling in
7740 accordance to the "Declarations" section in the "Basic Concepts"
7741 chapter in the ECMA C# spec.
7743 * interface.cs: Make all interface member classes derive from
7744 InterfaceMemberBase.
7746 2001-05-07 Miguel de Icaza <miguel@ximian.com>
7748 * Many things: all interfaces are parsed and generated in
7749 gen-treedump. Support for member variables, constructors,
7750 destructors, properties, constants is there.
7752 Beginning of the IL backend, but very little done, just there for
7755 2001-04-29 Miguel de Icaza <miguel@ximian.com>
7757 * cs-parser.jay: Fix labeled statement.
7759 * cs-tokenizer.cs (escape): Escape " and ' always.
7760 ref_line, ref_name: keep track of the line/filename as instructed
7761 by #line by the compiler.
7764 2001-04-27 Miguel de Icaza <miguel@ximian.com>
7766 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
7767 to match the values in System.CodeDOM.
7769 Divid renamed to Divide.
7771 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
7773 (Statements.set): remove.
7775 * System.CodeDOM/CodeCatchClause.cs: always have a valid
7778 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
7779 falseStatements always have valid values.
7781 * cs-parser.jay: Use System.CodeDOM now.
