1 2002-09-18 Miguel de Icaza <miguel@ximian.com>
3 * ecore.cs (SimpleName.DoResolveType): During the initial type
4 resolution process, when we define types recursively, we must
5 check first for types in our current scope before we perform
6 lookups in the enclosing scopes.
8 * expression.cs (MakeByteBlob): Handle Decimal blobs.
10 (Invocation.VerifyArgumentsCompat): Call
11 TypeManager.TypeToCoreType on the parameter_type.GetElementType.
12 I thought we were supposed to always call this, but there are a
13 few places in the code where we dont do it.
15 2002-09-17 Miguel de Icaza <miguel@ximian.com>
17 * driver.cs: Add support in -linkres and -resource to specify the
18 name of the identifier.
20 2002-09-16 Miguel de Icaza <miguel@ximian.com>
22 * ecore.cs (StandardConversionExists): Sync with the conversion
23 code: allow anything-* to void* conversions.
25 (FindMostSpecificSource): Use an Expression argument
26 instead of a Type, because we might be handed over a Literal which
27 gets a few more implicit conversions that plain types do not. So
28 this information was being lost.
30 Also, we drop the temporary type-holder expression when not
33 2002-09-17 Martin Baulig <martin@gnome.org>
35 * class.cs (PropertyBase.CheckBase): Don't check the base class if
36 this is an explicit interface implementation.
38 2002-09-17 Martin Baulig <martin@gnome.org>
40 * class.cs (PropertyBase.CheckBase): Make this work for indexers with
41 different `IndexerName' attributes.
43 * expression.cs (BaseIndexerAccess): Rewrote this class to use IndexerAccess.
44 (IndexerAccess): Added special protected ctor for BaseIndexerAccess and
45 virtual CommonResolve().
47 2002-09-16 Miguel de Icaza <miguel@ximian.com>
49 * enum.cs (LookupEnumValue): Use the EnumConstant declared type,
50 and convert that to the UnderlyingType.
52 * statement.cs (Foreach.Resolve): Indexers are just like variables
55 * cs-tokenizer.cs (consume_string): Track line numbers and columns
56 inside quoted strings, we were not doing this before.
58 2002-09-16 Martin Baulig <martin@gnome.org>
60 * ecore.cs (MethodGroupExpr.DoResolve): If we have an instance expression,
61 resolve it. This is needed for the definite assignment check of the
62 instance expression, fixes bug #29846.
63 (PropertyExpr.DoResolve, EventExpr.DoResolve): Likewise.
65 2002-09-16 Nick Drochak <ndrochak@gol.com>
67 * parameter.cs: Fix compile error. Cannot reference static member
68 from an instance object. Is this an mcs bug?
70 2002-09-14 Martin Baulig <martin@gnome.org>
72 * decl.cs (MemberCache.SetupCacheForInterface): Don't add an interface
73 multiple times. Fixes bug #30295, added test-166.cs.
75 2002-09-14 Martin Baulig <martin@gnome.org>
77 * statement.cs (Block.Emit): Don't emit unreachable code.
78 (Switch.SimpleSwitchEmit, Switch.TableSwitchEmit): Check for missing
80 (Goto.Emit, Continue.Emit): Set ec.Breaks = true.
82 2002-09-14 Martin Baulig <martin@gnome.org>
84 * parameter.cs (Parameter.Attributes): Make this work if Modifier.ISBYREF
87 2002-09-14 Martin Baulig <martin@gnome.org>
89 * typemanager.cs (TypeManager.IsNestedChildOf): This must return false
90 if `type == parent' since in this case `type.IsSubclassOf (parent)' will
91 be false on the ms runtime.
93 2002-09-13 Martin Baulig <martin@gnome.org>
95 * ecore.cs (SimpleName.SimpleNameResolve): Include the member name in
96 the CS0038 error message.
98 2002-09-12 Miguel de Icaza <miguel@ximian.com>
100 * expression.cs (CheckedExpr, UnCheckedExpr): If we have a
101 constant inside, return it.
103 2002-09-12 Martin Baulig <martin@gnome.org>
105 * cfold.cs (ConstantFold.DoConstantNumericPromotions): Check whether an
106 implicit conversion can be done between enum types.
108 * enum.cs (Enum.LookupEnumValue): If the value is an EnumConstant,
109 check whether an implicit conversion to the current enum's UnderlyingType
110 exists and report an error if not.
112 * codegen.cs (CodeGen.Init): Delete the symbol file when compiling
113 without debugging support.
115 * delegate.cs (Delegate.CloseDelegate): Removed, use CloseType instead.
116 Fixes bug #30235. Thanks to Ricardo Fernández Pascual.
118 2002-09-12 Martin Baulig <martin@gnome.org>
120 * typemanager.cs (TypeManager.IsNestedChildOf): New method.
122 * ecore.cs (IMemberExpr.DeclaringType): New property.
123 (SimpleName.SimpleNameResolve): Check whether we're accessing a
124 nonstatic member of an outer type (CS0038).
126 2002-09-11 Miguel de Icaza <miguel@ximian.com>
128 * driver.cs: Activate the using-error detector at warning level
129 4 (at least for MS-compatible APIs).
131 * namespace.cs (VerifyUsing): Small buglett fix.
133 * pending.cs (PendingImplementation): pass the container pointer.
135 * interface.cs (GetMethods): Allow for recursive definition. Long
136 term, I would like to move every type to support recursive
137 definitions, not the current ordering mechanism that we have right
140 The situation is this: Attributes are handled before interfaces,
141 so we can apply attributes to interfaces. But some attributes
142 implement interfaces, we will now handle the simple cases
143 (recursive definitions will just get an error).
145 * parameter.cs: Only invalidate types at the end if we fail to
148 2002-09-09 Martin Baulig <martin@gnome.org>
150 * ecore.cs (PropertyExpr.Emit): Also check for
151 TypeManager.system_int_array_get_length so this'll also work when
152 compiling corlib. Fixes #30003.
154 2002-09-09 Martin Baulig <martin@gnome.org>
156 * expression.cs (ArrayCreation.MakeByteBlob): Added support for enums
157 and throw an exception if we can't get the type's size. Fixed #30040,
160 2002-09-09 Martin Baulig <martin@gnome.org>
162 * ecore.cs (PropertyExpr.DoResolve): Added check for static properies.
164 * expression.cs (SizeOf.DoResolve): Sizeof is only allowed in unsafe
165 context. Fixes bug #30027.
167 * delegate.cs (NewDelegate.Emit): Use OpCodes.Ldvirtftn for
168 virtual functions. Fixes bug #30043, added test-164.cs.
170 2002-09-08 Ravi Pratap <ravi@ximian.com>
172 * attribute.cs : Fix a small NullRef crash thanks to my stupidity.
174 2002-09-08 Nick Drochak <ndrochak@gol.com>
176 * driver.cs: Use an object to get the windows codepage since it's not a
179 2002-09-08 Miguel de Icaza <miguel@ximian.com>
181 * statement.cs (For.Emit): for infinite loops (test == null)
182 return whether there is a break inside, not always "true".
184 * namespace.cs (UsingEntry): New struct to hold the name of the
185 using definition, the location where it is defined, and whether it
186 has been used in a successful type lookup.
188 * rootcontext.cs (NamespaceLookup): Use UsingEntries instead of
193 2002-09-06 Ravi Pratap <ravi@ximian.com>
195 * attribute.cs : Fix incorrect code which relied on catching
196 a NullReferenceException to detect a null being passed in
197 where an object was expected.
199 2002-09-06 Miguel de Icaza <miguel@ximian.com>
201 * statement.cs (Try): flag the catch variable as assigned
203 * expression.cs (Cast): Simplified by using ResolveType instead of
206 * statement.cs (Catch): Fix bug by using ResolveType.
208 2002-09-06 Ravi Pratap <ravi@ximian.com>
210 * expression.cs (BetterConversion): Special case for when we have
211 a NullLiteral as the argument and we have to choose between string
212 and object types - we choose string the way csc does.
214 * attribute.cs (Attribute.Resolve): Catch the
215 NullReferenceException and report error #182 since the Mono
216 runtime no more has the bug and having this exception raised means
217 we tried to select a constructor which takes an object and is
220 2002-09-05 Ravi Pratap <ravi@ximian.com>
222 * expression.cs (Invocation.OverloadResolve): Flag a nicer error
223 message (1502, 1503) when we can't locate a method after overload
224 resolution. This is much more informative and closes the bug
227 * interface.cs (PopulateMethod): Return if there are no argument
228 types. Fixes a NullReferenceException bug.
230 * attribute.cs (Attribute.Resolve): Ensure we allow TypeOf
231 expressions too. Previously we were checking only in one place for
232 positional arguments leaving out named arguments.
234 * ecore.cs (ImplicitNumericConversion): Conversion from underlying
235 type to the enum type is not allowed. Remove code corresponding to
238 (ConvertNumericExplicit): Allow explicit conversions from
239 the underlying type to enum type. This precisely follows the spec
240 and closes a bug filed by Gonzalo.
242 2002-09-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
245 * compiler.csproj.user: patch from Adam Chester (achester@bigpond.com).
247 2002-09-03 Miguel de Icaza <miguel@ximian.com>
249 * statement.cs (SwitchLabel.ResolveAndReduce): In the string case,
250 it was important that we stored the right value after the
251 reduction in `converted'.
253 2002-09-04 Martin Baulig <martin@gnome.org>
255 * location.cs (Location.SymbolDocument): Use full pathnames for the
258 2002-08-30 Miguel de Icaza <miguel@ximian.com>
260 * expression.cs (ComposedCast): Use DeclSparce.ResolveType instead
261 of the expression resolve mechanism, because that will catch the
262 SimpleName error failures.
264 (Conditional): If we can not resolve the
265 expression, return, do not crash.
267 2002-08-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
270 (location): display token name instead of its number.
272 2002-08-28 Martin Baulig <martin@gnome.org>
274 * expression.cs (Binary.ResolveOperator): Don't silently return
275 but return an error if an operator cannot be applied between two
278 2002-08-28 Martin Baulig <martin@gnome.org>
280 * class.cs (Constructor.Define): Set the permission attributes
281 correctly instead of making all constructors public.
283 2002-08-28 Martin Baulig <martin@gnome.org>
285 * ecore.cs (Expression.DoResolve): Do a TypeManager.MemberLook
286 for private members before reporting a CS0103; if we find anything,
289 2002-08-28 Martin Baulig <martin@gnome.org>
291 * typemanager.cs (TypeManager.FilterWithClosure): It's not enough
292 to check whether `closure_start_type == closure_invocation_type',
293 we also need to check whether `m.DeclaringType == closure_invocation_type'
294 before bypassing the permission checks. We might be accessing
295 protected/private members from the base class.
296 (TypeManager.RealMemberLookup): Only set private_ok if private
297 members were requested via BindingFlags.NonPublic.
299 * ecore.cs (MethodGroupExpr.IsExplicitImpl): New property.
301 * expression.cs (MemberAccess.ResolveMemberAccess): Set
302 MethodGroupExpr.IsExplicitImpl if appropriate.
303 (Invocation.DoResolve): Don't report the CS0120 for explicit
304 interface implementations.
306 2002-08-27 Martin Baulig <martin@gnome.org>
308 * expression.cs (Invocation.DoResolve): If this is a static
309 method and we don't have an InstanceExpression, we must report
312 2002-08-25 Martin Baulig <martin@gnome.org>
314 * expression.cs (Binary.ResolveOperator): Don't allow `!=' and
315 `==' between a valuetype and an object.
317 2002-08-25 Miguel de Icaza <miguel@ximian.com>
319 * ecore.cs (TypeExpr): Provide a ToString method.
321 2002-08-24 Martin Baulig <martin@gnome.org>
323 * codegen.cs (CodeGen.InitMonoSymbolWriter): The symbol file is
324 now called proggie.dbg and it's a binary file.
326 2002-08-23 Martin Baulig <martin@gnome.org>
328 * decl.cs (MemberCache.AddMethods): Ignore varargs methods.
330 2002-08-23 Martin Baulig <martin@gnome.org>
332 * struct.cs (MyStructInfo.ctor): Make this work with empty
333 structs; it's not allowed to use foreach() on null.
335 2002-08-23 Martin Baulig <martin@gnome.org>
337 * codegen.cs (CodeGen.InitMonoSymbolWriter): Tell the symbol
338 writer the full pathname of the generated assembly.
340 2002-08-23 Martin Baulig <martin@gnome.org>
342 * statements.cs (FlowBranching.UsageVector.MergeChildren):
343 A `finally' block never returns or breaks; improved handling of
346 2002-08-23 Martin Baulig <martin@gnome.org>
348 * statement.cs (Throw.Resolve): Allow `throw null'.
350 2002-08-23 Martin Baulig <martin@gnome.org>
352 * expression.cs (MemberAccess.ResolveMemberAccess): If this is an
353 EventExpr, don't do a DeclaredOnly MemberLookup, but check whether
354 `ee.EventInfo.DeclaringType == ec.ContainerType'. The
355 MemberLookup would return a wrong event if this is an explicit
356 interface implementation and the class has an event with the same
359 2002-08-23 Martin Baulig <martin@gnome.org>
361 * statement.cs (Block.AddChildVariableNames): New public method.
362 (Block.AddChildVariableName): Likewise.
363 (Block.IsVariableNameUsedInChildBlock): Likewise.
364 (Block.AddVariable): Check whether a variable name has already
365 been used in a child block.
367 * cs-parser.jay (declare_local_variables): Mark all variable names
368 from the current block as being used in a child block in the
371 2002-08-23 Martin Baulig <martin@gnome.org>
373 * codegen.cs (CodeGen.InitializeSymbolWriter): Abort if we can't
374 find the symbol writer.
376 * driver.cs: csc also allows the arguments to /define being
377 separated by commas, not only by semicolons.
379 2002-08-23 Martin Baulig <martin@gnome.org>
381 * interface.cs (Interface.GetMembers): Added static check for events.
383 2002-08-15 Martin Baulig <martin@gnome.org>
385 * class.cs (MethodData.EmitDestructor): In the Expression.MemberLookup
386 call, use ec.ContainerType.BaseType as queried_type and invocation_type.
388 * ecore.cs (Expression.MemberLookup): Added documentation and explained
389 why the MethodData.EmitDestructor() change was necessary.
391 2002-08-20 Martin Baulig <martin@gnome.org>
393 * class.cs (TypeContainer.FindMembers): Added static check for events.
395 * decl.cs (MemberCache.AddMembers): Handle events like normal members.
397 * typemanager.cs (TypeHandle.GetMembers): When queried for events only,
398 use Type.GetEvents(), not Type.FindMembers().
400 2002-08-20 Martin Baulig <martin@gnome.org>
402 * decl.cs (MemberCache): Added a special method cache which will
403 be used for method-only searched. This ensures that a method
404 search will return a MethodInfo with the correct ReflectedType for
407 2002-08-20 Martin Baulig <martin@gnome.org>
409 * decl.cs (DeclSpace.FindMembers): Made this public.
411 2002-08-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
413 * delegate.cs: fixed build on windows.
414 [FIXME: Filed as bug #29150: MCS must report these errors.]
416 2002-08-19 Ravi Pratap <ravi@ximian.com>
418 * ecore.cs (StandardConversionExists): Return a false
419 if we are trying to convert the void type to anything else
420 since that is not allowed.
422 * delegate.cs (DelegateInvocation.DoResolve): Ensure that
423 we flag error 70 in the event an event is trying to be accessed
424 directly from outside the declaring type.
426 2002-08-20 Martin Baulig <martin@gnome.org>
428 * typemanager.cs, decl.cs: Moved MemberList, IMemberContainer and
429 MemberCache from typemanager.cs to decl.cs.
431 2002-08-19 Martin Baulig <martin@gnome.org>
433 * class.cs (TypeContainer): Implement IMemberContainer.
434 (TypeContainer.DefineMembers): Create the MemberCache.
435 (TypeContainer.FindMembers): Do better BindingFlags checking; only
436 return public members if BindingFlags.Public was given, check
437 whether members are static.
439 2002-08-16 Martin Baulig <martin@gnome.org>
441 * decl.cs (DeclSpace.Define): Splitted this in Define and
442 DefineMembers. DefineMembers is called first and initializes the
445 * rootcontext.cs (RootContext.DefineMembers): New function. Calls
446 DefineMembers() on all our DeclSpaces.
448 * class.cs (TypeContainer.Define): Moved all code to DefineMembers(),
449 but call DefineMembers() on all nested interfaces. We call their
450 Define() in our new Define() function.
452 * interface.cs (Interface): Implement IMemberContainer.
453 (Interface.Define): Moved all code except the attribute stuf to
455 (Interface.DefineMembers): Initialize the member cache.
457 * typemanager.cs (IMemberFinder): Removed this interface, we don't
458 need this anymore since we can use MemberCache.FindMembers directly.
460 2002-08-19 Martin Baulig <martin@gnome.org>
462 * typemanager.cs (MemberCache): When creating the cache for an
463 interface type, add all inherited members.
464 (TypeManager.MemberLookup_FindMembers): Changed `ref bool searching'
465 to `out bool used_cache' and documented it.
466 (TypeManager.MemberLookup): If we already used the cache in the first
467 iteration, we don't need to do the interfaces check.
469 2002-08-19 Martin Baulig <martin@gnome.org>
471 * decl.cs (DeclSpace.FindMembers): New abstract method. Moved this
472 here from IMemberFinder and don't implement this interface anymore.
473 (DeclSpace.MemberCache): Moved here from IMemberFinder.
475 * typemanager.cs (IMemberFinder): This interface is now only used by
476 classes which actually support the member cache.
477 (TypeManager.builder_to_member_finder): Renamed to builder_to_declspace
478 since we only put DeclSpaces into this Hashtable.
479 (MemberLookup_FindMembers): Use `builder_to_declspace' if the type is
480 a dynamic type and TypeHandle.GetTypeHandle() otherwise.
482 2002-08-16 Martin Baulig <martin@gnome.org>
484 * typemanager.cs (ICachingMemberFinder): Removed.
485 (IMemberFinder.MemberCache): New property.
486 (TypeManager.FindMembers): Merged this with RealFindMembers().
487 This function will never be called from TypeManager.MemberLookup()
488 so we can't use the cache here, just the IMemberFinder.
489 (TypeManager.MemberLookup_FindMembers): Check whether the
490 IMemberFinder has a MemberCache and call the cache's FindMembers
492 (MemberCache): Rewrote larger parts of this yet another time and
495 2002-08-15 Miguel de Icaza <miguel@ximian.com>
497 * driver.cs (LoadArgs): Support quoting.
499 (Usage): Show the CSC-like command line arguments.
501 Improved a few error messages.
503 2002-08-15 Martin Baulig <martin@gnome.org>
505 * typemanager.cs (IMemberContainer.Type): New property.
506 (IMemberContainer.IsInterface): New property.
508 The following changes are conditional to BROKEN_RUNTIME, which is
509 defined at the top of the file.
511 * typemanager.cs (MemberCache.MemberCache): Don't add the base
512 class'es members, but add all members from TypeHandle.ObjectType
513 if we're an interface.
514 (MemberCache.AddMembers): Set the Declared flag if member.DeclaringType
516 (MemberCache.CacheEntry.Container): Removed this field.
517 (TypeHandle.GetMembers): Include inherited members.
519 2002-08-14 Gonzalo Paniagua Javier <gonzalo@ximian.com>
521 * typemanager.cs: fixed compilation and added a comment on a field that
524 2002-08-15 Martin Baulig <martin@gnome.org>
526 * class.cs (ConstructorInitializer.Resolve): In the
527 Expression.MemberLookup call, use the queried_type as
530 * typemanager.cs (IMemberContainer.GetMembers): Removed the `bool
531 declared' attribute, it's always true.
532 (IMemberContainer.Parent, IMemberContainer.Name): New properties.
533 (TypeManager.MemberLookup_FindMembers): [FIXME FIXME FIXME] Added
534 temporary wrapper for FindMembers which tells MemberLookup whether
535 members from the base classes are included in the return value.
536 This will go away soon.
537 (TypeManager.MemberLookup): Use this temporary hack here; once the
538 new MemberCache is completed, we don't need to do the DeclaredOnly
539 looping here anymore since the MemberCache will take care of this.
540 (TypeManager.IsSubclassOrNestedChildOf): Allow `type == parent'.
541 (MemberCache): When creating the MemberCache for a class, get
542 members from the current class and all its base classes.
543 (MemberCache.CacheEntry.Container): New field. This is a
544 temporary hack until the Mono runtime is fixed to distinguish
545 between ReflectedType and DeclaringType. It allows us to use MCS
546 with both the MS runtime and the unfixed Mono runtime without
547 problems and without accecting performance.
548 (MemberCache.SearchMembers): The DeclaredOnly looping from
549 TypeManager.MemberLookup is now done here.
551 2002-08-14 Martin Baulig <martin@gnome.org>
553 * statement.cs (MyStructInfo.MyStructInfo): Don't call
554 Type.GetFields on dynamic types but get the fields from the
555 corresponding TypeContainer.
556 (MyStructInfo.GetStructInfo): Added check for enum types.
558 * typemanager.cs (MemberList.IsSynchronized): Implemented.
559 (MemberList.SyncRoot): Implemented.
560 (TypeManager.FilterWithClosure): No need to check permissions if
561 closure_start_type == closure_invocation_type, don't crash if
562 closure_invocation_type is null.
564 2002-08-13 Martin Baulig <martin@gnome.org>
566 Rewrote TypeContainer.FindMembers to use a member cache. This
567 gives us a speed increase of about 35% for the self-hosting MCS
568 build and of about 15-20% for the class libs (both on GNU/Linux).
570 * report.cs (Timer): New class to get enhanced profiling. This
571 whole class is "TIMER" conditional since it remarkably slows down
574 * class.cs (MemberList): New class. This is an IList wrapper
575 which we're now using instead of passing MemberInfo[]'s around to
576 avoid copying this array unnecessarily.
577 (IMemberFinder.FindMember): Return a MemberList, not a MemberInfo [].
578 (ICachingMemberFinder, IMemberContainer): New interface.
579 (TypeManager.FilterWithClosure): If `criteria' is null, the name
580 has already been checked, otherwise use it for the name comparision.
581 (TypeManager.FindMembers): Renamed to RealMemberFinder and
582 provided wrapper which tries to use ICachingMemberFinder.FindMembers
583 if possible. Returns a MemberList, not a MemberInfo [].
584 (TypeHandle): New class, implements IMemberContainer. We create
585 one instance of this class per type, it contains a MemberCache
586 which is used to do the member lookups.
587 (MemberCache): New class. Each instance of this class contains
588 all members of a type and a name-based hash table.
589 (MemberCache.FindMembers): This is our new member lookup
590 function. First, it looks up all members of the requested name in
591 the hash table. Then, it walks this list and sorts out all
592 applicable members and returns them.
594 2002-08-13 Martin Baulig <martin@gnome.org>
596 In addition to a nice code cleanup, this gives us a performance
597 increase of about 1.4% on GNU/Linux - not much, but it's already
598 half a second for the self-hosting MCS compilation.
600 * typemanager.cs (IMemberFinder): New interface. It is used by
601 TypeManager.FindMembers to call FindMembers on a TypeContainer,
602 Enum, Delegate or Interface.
603 (TypeManager.finder_to_member_finder): New PtrHashtable.
604 (TypeManager.finder_to_container): Removed.
605 (TypeManager.finder_to_delegate): Removed.
606 (TypeManager.finder_to_interface): Removed.
607 (TypeManager.finder_to_enum): Removed.
609 * interface.cs (Interface): Implement IMemberFinder.
611 * delegate.cs (Delegate): Implement IMemberFinder.
613 * enum.cs (Enum): Implement IMemberFinder.
615 * class.cs (TypeContainer): Implement IMemberFinder.
617 2002-08-12 Martin Baulig <martin@gnome.org>
619 * ecore.cs (TypeExpr.DoResolveType): Mark this as virtual.
621 2002-08-12 Martin Baulig <martin@gnome.org>
623 * ecore.cs (ITypeExpression): New interface for expressions which
625 (TypeExpression): Renamed to TypeLookupExpression.
626 (Expression.DoResolve): If we're doing a types-only lookup, the
627 expression must implement the ITypeExpression interface and we
628 call DoResolveType() on it.
629 (SimpleName): Implement the new ITypeExpression interface.
630 (SimpleName.SimpleNameResolve): Removed the ec.OnlyLookupTypes
631 hack, the situation that we're only looking up types can't happen
632 anymore when this method is called. Moved the type lookup code to
633 DoResolveType() and call it.
634 (SimpleName.DoResolveType): This ITypeExpression interface method
635 is now doing the types-only lookup.
636 (TypeExpr, TypeLookupExpression): Implement ITypeExpression.
637 (ResolveFlags): Added MaskExprClass.
639 * expression.cs (MemberAccess): Implement the ITypeExpression
641 (MemberAccess.DoResolve): Added support for a types-only lookup
642 when we're called via ITypeExpression.DoResolveType().
643 (ComposedCast): Implement the ITypeExpression interface.
645 * codegen.cs (EmitContext.OnlyLookupTypes): Removed. Call
646 Expression.Resolve() with ResolveFlags.Type instead.
648 2002-08-12 Martin Baulig <martin@gnome.org>
650 * interface.cs (Interface.Define): Apply attributes.
652 * attribute.cs (Attribute.ApplyAttributes): Added support for
653 interface attributes.
655 2002-08-11 Martin Baulig <martin@gnome.org>
657 * statement.cs (Block.Emit): Only check the "this" variable if we
658 do not always throw an exception.
660 * ecore.cs (PropertyExpr.DoResolveLValue): Implemented, check
661 whether the property has a set accessor.
663 2002-08-11 Martin Baulig <martin@gnome.org>
665 Added control flow analysis support for structs.
667 * ecore.cs (ResolveFlags): Added `DisableFlowAnalysis' to resolve
668 with control flow analysis turned off.
669 (IVariable): New interface.
670 (SimpleName.SimpleNameResolve): If MemberAccess.ResolveMemberAccess
671 returns an IMemberExpr, call DoResolve/DoResolveLValue on it.
672 (FieldExpr.DoResolve): Resolve the instance expression with flow
673 analysis turned off and do the definite assignment check after the
674 resolving when we know what the expression will resolve to.
676 * expression.cs (LocalVariableReference, ParameterReference):
677 Implement the new IVariable interface, only call the flow analysis
678 code if ec.DoFlowAnalysis is true.
679 (This): Added constructor which takes a Block argument. Implement
680 the new IVariable interface.
681 (MemberAccess.DoResolve, MemberAccess.DoResolveLValue): Call
682 DoResolve/DoResolveLValue on the result of ResolveMemberLookup().
683 This does the definite assignment checks for struct members.
685 * class.cs (Constructor.Emit): If this is a non-static `struct'
686 constructor which doesn't have any initializer, call
687 Block.AddThisVariable() to tell the flow analysis code that all
688 struct elements must be initialized before control returns from
691 * statement.cs (MyStructInfo): New public class.
692 (UsageVector.this [VariableInfo vi]): Added `int field_idx'
693 argument to this indexer. If non-zero, check an individual struct
694 member, not the whole struct.
695 (FlowBranching.CheckOutParameters): Check struct members.
696 (FlowBranching.IsVariableAssigned, SetVariableAssigned): Added
697 overloaded versions of these methods which take an additional
698 `int field_idx' argument to check struct members.
699 (FlowBranching.IsParameterAssigned, SetParameterAssigned): Added
700 overloaded versions of these methods which take an additional
701 `string field_name' argument to check struct member.s
702 (VariableInfo): Implement the IVariable interface.
703 (VariableInfo.StructInfo): New public property. Returns the
704 MyStructInfo instance of the variable if it's a struct or null.
705 (Block.AddThisVariable): New public method. This is called from
706 Constructor.Emit() for non-static `struct' constructor which do
707 not have any initializer. It creates a special variable for the
708 "this" instance variable which will be checked by the flow
709 analysis code to ensure that all of the struct's fields are
710 initialized before control returns from the constructor.
711 (UsageVector): Added support for struct members. If a
712 variable/parameter is a struct with N members, we reserve a slot
713 in the usage vector for each member. A struct is considered fully
714 initialized if either the struct itself (slot 0) or all its
715 members are initialized.
717 2002-08-08 Martin Baulig <martin@gnome.org>
719 * driver.cs (Driver.MainDriver): Only report an error CS5001
720 if there were no compilation errors.
722 * codegen.cs (EmitContext.EmitContext): Use the DeclSpace's
723 `UnsafeContext' property to determine whether the parent is in
724 unsafe context rather than checking the parent's ModFlags:
725 classes nested in an unsafe class are unsafe as well.
727 2002-08-08 Martin Baulig <martin@gnome.org>
729 * statement.cs (UsageVector.MergeChildren): Distinguish between
730 `Breaks' and `Returns' everywhere, don't set `Breaks' anymore if
731 we return. Added test17() and test18() to test-154.cs.
733 2002-08-08 Martin Baulig <martin@gnome.org>
735 * typemanager.cs (TypeManager.FilterWithClosure): If we have
736 Family access, make sure the invoking type isn't a subclass of the
737 queried type (that'd be a CS1540).
739 * ecore.cs (Expression.MemberLookup): Added overloaded version of
740 this method which takes an additional `Type invocation_type'.
742 * expression.cs (BaseAccess.DoResolve): Use the base type as
743 invocation and query type.
744 (MemberAccess.DoResolve): If the lookup failed and we're about to
745 report a CS0122, try a lookup with the ec.ContainerType - if this
746 succeeds, we must report a CS1540.
748 2002-08-08 Martin Baulig <martin@gnome.org>
750 * ecore.cs (IMemberExpr): Added `bool IsInstance' property.
751 (MethodGroupExpr): Implement the IMemberExpr interface.
753 * expression (MemberAccess.ResolveMemberAccess): No need to have
754 any special code for MethodGroupExprs anymore, they're now
757 2002-08-08 Martin Baulig <martin@gnome.org>
759 * typemanager.cs (TypeManager.FilterWithClosure): Check Assembly,
760 Family, FamANDAssem and FamORAssem permissions.
761 (TypeManager.IsSubclassOrNestedChildOf): New public method.
763 2002-08-08 Martin Baulig <martin@gnome.org>
765 * statement.cs (FlowBranchingType): Added LOOP_BLOCK.
766 (UsageVector.MergeChildren): `break' breaks unless we're in a switch
769 Thu Aug 8 10:28:07 CEST 2002 Paolo Molaro <lupus@ximian.com>
771 * driver.cs: implemented /resource option to embed managed resources.
773 2002-08-07 Martin Baulig <martin@gnome.org>
775 * class.cs (FieldBase.Initializer): Renamed to `init' and made private.
776 (FieldBase.HasFieldInitializer): New public property.
777 (FieldBase.GetInitializerExpression): New public method. Resolves and
778 returns the field initializer and makes sure it is only resolved once.
779 (TypeContainer.EmitFieldInitializers): Call
780 FieldBase.GetInitializerExpression to get the initializer, this ensures
781 that it isn't resolved multiple times.
783 * codegen.cs (EmitContext): Added `bool IsFieldInitialier'. This tells
784 the resolving process (SimpleName/MemberLookup) that we're currently
785 emitting a field initializer (which must not access any instance members,
786 this is an error CS0236).
788 * ecore.cs (SimpleName.Error_ObjectRefRequired): Added EmitContext
789 argument, if the `IsFieldInitializer' flag is set, we must report and
790 error CS0236 and not an error CS0120.
792 2002-08-07 Martin Baulig <martin@gnome.org>
794 * ecore.cs (IMemberExpr): New public interface.
795 (FieldExpr, PropertyExpr, EventExpr): Implement IMemberExpr.
796 (SimpleName.SimpleNameResolve): Call MemberAccess.ResolveMemberAccess
797 if the expression is an IMemberExpr.
799 * expression.cs (MemberAccess.ResolveMemberAccess): Allow `left'
800 to be null, implicitly default to `this' if we're non-static in
801 this case. Simplified the code a lot by using the new IMemberExpr
802 interface. Also fixed bug #28176 here.
804 2002-08-06 Martin Baulig <martin@gnome.org>
806 * cs-parser.jay (SimpleLookup): Removed. We need to create
807 ParameterReferences during semantic analysis so that we can do a
808 type-only search when resolving Cast, TypeOf and SizeOf.
809 (block): Pass the `current_local_parameters' to the Block's
812 * class.cs (ConstructorInitializer): Added `Parameters parameters'
813 argument to the constructor.
814 (ConstructorInitializer.Resolve): Create a temporary implicit
815 block with the parameters.
817 * ecore.cs (SimpleName.SimpleNameResolve): Resolve parameter
818 references here if we aren't doing a type-only search.
820 * statement.cs (Block): Added constructor which takes a
821 `Parameters parameters' argument.
822 (Block.Parameters): New public property.
824 * support.cs (InternalParameters.Parameters): Renamed `parameters'
825 to `Parameters' and made it public readonly.
827 2002-08-06 Martin Baulig <martin@gnome.org>
829 * ecore.cs (Expression.Warning): Made this public as well.
831 * report.cs (Report.Debug): Print the contents of collections.
833 2002-08-06 Martin Baulig <martin@gnome.org>
835 * ecore.cs (Expression.ResolveFlags): New [Flags] enum. This is
836 used to tell Resolve() which kinds of expressions it may return.
837 (Expression.Resolve): Added overloaded version of this method which
838 takes a `ResolveFlags flags' argument. This can be used to tell
839 Resolve() which kinds of expressions it may return. Reports a
841 (Expression.ResolveWithSimpleName): Removed, use Resolve() with
842 ResolveFlags.SimpleName.
843 (Expression.Error118): Added overloaded version of this method which
844 takes a `ResolveFlags flags' argument. It uses the flags to determine
845 which kinds of expressions are allowed.
847 * expression.cs (Argument.ResolveMethodGroup): New public method.
848 Resolves an argument, but allows a MethodGroup to be returned.
849 This is used when invoking a delegate.
851 * TODO: Updated a bit.
853 2002-08-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
855 Fixed compilation with csc.
857 * ecore.cs: Expression.Error made public. Is this correct? Should
858 Warning be made public too?
860 * expression.cs: use ea.Location instead of ea.loc.
861 [FIXME: Filed as bug #28607: MCS must report these errors.]
863 2002-08-06 Martin Baulig <martin@gnome.org>
865 * ecore.cs (Expression.loc): Moved the location here instead of
866 duplicating it in all derived classes.
867 (Expression.Location): New public property.
868 (Expression.Error, Expression.Warning): Made them non-static and
869 removed the location argument.
870 (Expression.Warning): Added overloaded version which takes an
871 `int level' argument.
872 (Expression.Error118): Make this non-static and removed the
873 expression and location arguments.
874 (TypeExpr): Added location argument to the constructor.
876 * expression.cs (StaticCallExpr): Added location argument to
878 (Indirection, PointerArithmetic): Likewise.
879 (CheckedExpr, UnCheckedExpr): Likewise.
880 (ArrayAccess, IndexerAccess, UserCast, ArrayPtr): Likewise.
881 (StringPtr): Likewise.
884 2002-08-05 Martin Baulig <martin@gnome.org>
886 * expression.cs (BaseAccess.DoResolve): Actually report errors.
888 * assign.cs (Assign.DoResolve): Check whether the source
889 expression is a value or variable.
891 * statement.cs (Try.Resolve): Set ec.InTry/InCatch/InFinally
892 while resolving the corresponding blocks.
894 * interface.cs (Interface.GetInterfaceTypeByName): Actually report
895 an error, don't silently return null.
897 * statement.cs (Block.AddVariable): Do the error reporting here
898 and distinguish between CS0128 and CS0136.
899 (Block.DoResolve): Report all unused labels (warning CS0164).
900 (LabeledStatement): Pass the location to the constructor.
901 (LabeledStatement.HasBeenReferenced): New property.
902 (LabeledStatement.Resolve): Set it to true here.
904 * statement.cs (Return.Emit): Return success even after reporting
905 a type mismatch error (CS0126 or CS0127), this is what csc does and
906 it avoids confusing the users with any consecutive errors.
908 2002-08-05 Martin Baulig <martin@gnome.org>
910 * enum.cs (Enum.LookupEnumValue): Catch circular definitions.
912 * const.cs (Const.LookupConstantValue): Catch circular definitions.
914 * expression.cs (MemberAccess.DoResolve): Silently return if an
915 error has already been reported.

918 error has already been reported.
920 2002-08-05 Martin Baulig <martin@gnome.org>
922 * statement.cs (UsageVector): Only initialize the `parameters'
923 vector if we actually have any "out" parameters.
925 2002-08-05 Martin Baulig <martin@gnome.org>
927 * expression.cs (Binary.ResolveOperator): When combining delegates,
928 they must have the same type.
930 2002-08-05 Martin Baulig <martin@gnome.org>
932 * typemanager.cs (TypeManager.GetArgumentTypes): Don't call
933 PropertyInfo.GetIndexParameters() on dynamic types, this doesn't
934 work with the ms runtime and we also don't need it: if we're a
935 PropertyBuilder and not in the `indexer_arguments' hash, then we
936 are a property and not an indexer.
938 * class.cs (TypeContainer.AsAccessible): Use Type.IsArray,
939 Type.IsPointer and Type.IsByRef instead of Type.HasElementType
940 since the latter one doesn't work with the ms runtime.

951 and it's not marked abstract or extern.
952 (PropertyBase): New abstract base class for Property and Indexer.
953 (PropertyBase.CheckBase): Moved here from Property and made it work
955 (PropertyBase.Emit): Moved here from Property.Emit, Indexer.Emit is
956 the same so we can reuse it there.
957 (Property, Indexer): Derive from PropertyBase.
958 (MethodSignature.inheritable_property_signature_filter): New delegate
959 to find properties and indexers.
961 * decl.cs (MemberCore.CheckMethodAgainstBase): Added `string name'
962 argument and improved error reporting.
964 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): Renamed to
965 EmptyReadOnlyParameters and made it a property.

993 top-level types and private for nested types.
994 (Enum.DefineType): Compute the correct visibility.
996 * modifiers.cs (Modifiers.TypeAttr): Added a version of this
997 function which takes a `bool is_toplevel' instead of a TypeContainer.
999 * typemanager.cs (TypeManager.IsBuiltinType): `void' is also a
1002 2002-08-02 Martin Baulig <martin@gnome.org>
1004 * expression.cs (LocalVariableReferenc): Added constructor which
1005 takes additional `VariableInfo vi' and `bool is_readonly' arguments.
1006 (LocalVariableReference.IsReadOnly): New property.
1007 (LocalVariableReference.DoResolveLValue): Report a CS1604 if the
1008 variable is readonly, use our own readonly flag to do this; you can
1009 use the new constructor to get a writable reference to a read-only
1012 * cs-parser.jay (foreach_statement, using_statement): Get a writable
1013 reference to the local variable.
1015 2002-08-01 Miguel de Icaza <miguel@ximian.com>
1017 * rootcontext.cs (ResolveCore): Also include System.Exception
1019 * statement.cs (Block.Emit): Do not emit the dead-code warnings if
1020 we reach an EmptyStatement.
1022 (Catch.DoResolve, Throw.DoResolve): Throwing the System.Exception
1025 * expression.cs (Binary.ResolveOperator): Check error result in
1028 use brtrue/brfalse directly and avoid compares to null.
1030 2002-08-02 Martin Baulig <martin@gnome.org>
1032 * class.cs (TypeContainer.Define): Define all nested interfaces here.
1033 Fixes bug #28407, added test-155.cs.

1105 local variables in this block (including the locals from all parent
1107 (Block.EmitMeta): Number all the variables.

1150 (Parameter.GetParameterInfo (DeclSpace, int, out bool)): Changed
1151 the out parameter to `out Parameter.Modifier mod', also set the
1152 Parameter.Modifier.ISBYREF flag on it if it's either ref or out.
1154 * support.cs (InternalParameters.ParameterModifier): Distinguish
1155 between Parameter.Modifier.OUT and Parameter.Modifier.REF, set the

1198 * cs-parser.jay (CSharpParser): Added `Stack switch_stack'.
1199 (switch_statement): Push the current_block to the switch_stack and
1200 pop it again when we're done with the switch.
1201 (switch_section): The new block is a child of the current_block.
1202 Fixes bug #24007, added test-152.cs.
1204 2002-07-27 Martin Baulig <martin@gnome.org>
1206 * expression.cs (Invocation.EmitArguments): When calling a varargs
1207 function with only its fixed arguments, we need to pass an empty
1210 2002-07-27 Martin Baulig <martin@gnome.org>
1212 Mono 0.13 has been released.
1214 2002-07-25 Miguel de Icaza <miguel@ximian.com>
1216 * driver.cs: Rename --resource to --linkres, because that is what
1217 we do currently, we dont support --resource yet.
1219 * cs-tokenizer.cs: Fix test for reporting endif mismatches.
1221 2002-07-25 Martin Baulig <martin@gnome.org>
1223 * class.cs (MethodData): New public class. This is a `method builder'
1224 class for a method or one accessor of a Property/Indexer/Event.
1225 (MethodData.GetMethodFlags): Moved here from MemberBase.
1226 (MethodData.ApplyAttributes): Likewise.
1227 (MethodData.ApplyObsoleteAttribute): Likewise.
1228 (MethodData.ApplyConditionalAttribute): Likewise.
1229 (MethodData.ApplyDllImportAttribute): Likewise.
1230 (MethodData.CheckAbstractAndExternal): Likewise.
1231 (MethodData.Define): Formerly knows as MemberBase.DefineMethod().
1232 (MethodData.Emit): Formerly known as Method.Emit().
1233 (MemberBase): Moved everything which was specific to a single
1234 accessor/method to MethodData.
1235 (Method): Create a new MethodData and call Define() and Emit() on it.
1236 (Property, Indexer, Event): Create a new MethodData objects for each
1237 accessor and call Define() and Emit() on them.
1239 2002-07-25 Martin Baulig <martin@gnome.org>
1241 Made MethodCore derive from MemberBase to reuse the code from there.
1242 MemberBase now also checks for attributes.
1244 * class.cs (MethodCore): Derive from MemberBase, not MemberCore.
1245 (MemberBase.GetMethodFlags): Moved here from class Method and marked
1247 (MemberBase.DefineAccessor): Renamed to DefineMethod(), added
1248 `CallingConventions cc' and `Attributes opt_attrs' arguments.
1249 (MemberBase.ApplyAttributes): New virtual method; applies the
1250 attributes to a method or accessor.
1251 (MemberBase.ApplyObsoleteAttribute): New protected virtual method.
1252 (MemberBase.ApplyConditionalAttribute): Likewise.
1253 (MemberBase.ApplyDllImportAttribute): Likewise.
1254 (MemberBase.CheckAbstractAndExternal): Likewise.
1255 (MethodCore.ParameterTypes): This is now a property instead of a
1256 method, it's initialized from DoDefineParameters().
1257 (MethodCore.ParameterInfo): Removed the set accessor.
1258 (MethodCore.DoDefineParameters): New protected virtual method to
1259 initialize ParameterTypes and ParameterInfo.
1260 (Method.GetReturnType): We can now simply return the MemberType.
1261 (Method.GetMethodFlags): Override the MemberBase version and add
1262 the conditional flags.
1263 (Method.CheckBase): Moved some code from Define() here, call
1264 DoDefineParameters() here.
1265 (Method.Define): Use DoDefine() and DefineMethod() from MemberBase
1266 here to avoid some larger code duplication.
1267 (Property.Emit, Indexer.Emit): Call CheckAbstractAndExternal() to
1268 ensure that abstract and external accessors don't declare a body.
1270 * attribute.cs (Attribute.GetValidPieces): Make this actually work:
1271 `System.Attribute.GetCustomAttributes (attr.Type)' does a recursive
1272 lookup in the attribute's parent classes, so we need to abort as soon
1273 as we found the first match.
1274 (Attribute.Obsolete_GetObsoleteMessage): Return the empty string if
1275 the attribute has no arguments.
1277 * typemanager.cs (TypeManager.AddMethod): Now takes a MemberBase instead
1280 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1282 * cs-parser.jay: reverted previous patch.
1284 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1286 * cs-parser.jay: fixed bug #22119.
1288 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1290 * attribute.cs: fixed compilation. The error was:
1291 "attribute.cs(571,17): error CS0177: The out parameter 'is_error' must
1292 be assigned to before control leaves the current method."
1293 [FIXME: Filed as bug #28186: MCS must report this error.]
1295 2002-07-25 Martin Baulig <martin@gnome.org>
1297 * attribute.cs (Attribute.Conditional_GetConditionName): New static
1298 method to pull the condition name ouf of a Conditional attribute.
1299 (Attribute.Obsolete_GetObsoleteMessage): New static method to pull
1300 the obsolete message and error flag out of an Obsolete attribute.
1302 * class.cs (Method.GetMethodFlags): New public method to get the
1303 TypeManager.MethodFlags for this method.
1304 (Method.ApplyConditionalAttribute, Method.ApplyObsoleteAttribute): New
1306 (Method.Define): Get and apply the Obsolete and Conditional attributes;
1307 if we're overriding a virtual function, set the new private variable
1308 `parent_method'; call the new TypeManager.AddMethod().
1310 * typemanager.cs (TypeManager.AddMethod): New static method. Stores
1311 the MethodBuilder and the Method in a PtrHashtable.
1312 (TypeManager.builder_to_method): Added for this purpose.
1313 (TypeManager.MethodFlags): Added IsObsoleteError.
1314 (TypeManager.GetMethodFlags): Added `Location loc' argument. Lookup
1315 Obsolete and Conditional arguments in MethodBuilders. If we discover
1316 an Obsolete attribute, emit an appropriate warning 618 / error 619 with
1317 the message from the attribute.
1319 2002-07-24 Martin Baulig <martin@gnome.org>
1321 * cs-tokenizer.cs: Eat up trailing whitespaces and one-line comments in
1322 preprocessor directives, ensure that the argument to #define/#undef is
1323 exactly one identifier and that it's actually an identifier.
1325 Some weeks ago I did a `#define DEBUG 1' myself and wondered why this
1328 2002-07-24 Martin Baulig <martin@gnome.org>
1330 * statement.cs (Foreach.ForeachHelperMethods): Added `Type element_type',
1331 initialize it to TypeManager.object_type in the constructor.
1332 (Foreach.GetEnumeratorFilter): Set `hm.element_type' to the return type
1333 of the `hm.get_current' method if we're using the collection pattern.
1334 (Foreach.EmitCollectionForeach): Use `hm.element_type' as the source type
1335 for the explicit conversion to make it work when we're using the collection
1336 pattern and the `Current' property has a different return type than `object'.
1339 2002-07-24 Martin Baulig <martin@gnome.org>
1341 * delegate.cs (Delegate.VerifyMethod): Simply return null if the method
1342 does not match, but don't report any errors. This method is called in
1343 order for all methods in a MethodGroupExpr until a matching method is
1344 found, so we don't want to bail out if the first method doesn't match.
1345 (NewDelegate.DoResolve): If none of the methods in the MethodGroupExpr
1346 matches, report the 123. Fixes #28070.
1348 2002-07-24 Martin Baulig <martin@gnome.org>
1350 * expression.cs (ArrayAccess.EmitStoreOpcode): Moved the
1351 TypeManager.TypeToCoreType() to the top of the method so the
1352 following equality checks will work. Fixes #28107.
1354 2002-07-24 Martin Baulig <martin@gnome.org>
1356 * cfold.cs (ConstantFold.DoConstantNumericPromotions): "If either
1357 operand is of type uint, and the other operand is of type sbyte,
1358 short or int, the operands are converted to type long." -
1359 Actually do what this comment already told us. Fixes bug #28106,
1362 2002-07-24 Martin Baulig <martin@gnome.org>
1364 * class.cs (MethodBase): New abstract class. This is now a base
1365 class for Property, Indexer and Event to avoid some code duplication
1366 in their Define() and DefineMethods() methods.
1367 (MethodBase.DoDefine, MethodBase.DefineAccessor): Provide virtual
1368 generic methods for Define() and DefineMethods().
1369 (FieldBase): Derive from MemberBase, not MemberCore.
1370 (Property): Derive from MemberBase, not MemberCore.
1371 (Property.DefineMethod): Moved all the code from this method to the
1372 new MethodBase.DefineAccessor(), just call it with appropriate
1374 (Property.Define): Call the new Property.DoDefine(), this does some
1375 sanity checks and we don't need to duplicate the code everywhere.
1376 (Event): Derive from MemberBase, not MemberCore.
1377 (Event.Define): Use the new MethodBase.DefineAccessor() to define the
1378 accessors, this will also make them work with interface events.
1379 (Indexer): Derive from MemberBase, not MemberCore.
1380 (Indexer.DefineMethod): Removed, call MethodBase.DefineAccessor() insstead.
1381 (Indexer.Define): Use the new MethodBase functions.
1383 * interface.cs (InterfaceEvent.InterfaceEvent): Added `Location loc'
1384 argument to the constructor.
1385 (Interface.FindMembers): Added support for interface events.
1386 (Interface.PopluateEvent): Implemented.
1388 Added test-149.cs for this. This also fixes bugs #26067 and #24256.
1390 2002-07-22 Miguel de Icaza <miguel@ximian.com>
1392 * class.cs (TypeContainer.AddMethod): Adding methods do not use IsValid,
1393 but this is required to check for a method name being the same as
1394 the containing class.
1398 2002-07-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1400 * interface.cs: initialize variable.
1402 2002-07-23 Martin Baulig <martin@gnome.org>
1404 Implemented the IndexerName attribute in interfaces.
1406 * class.cs (TypeContainer.DefineIndexers): Don't set the indexer
1407 name if this is an explicit interface implementation.
1408 (Indexer.InterfaceIndexerName): New public variable. If we're
1409 implementing an interface indexer, this is the IndexerName in that
1410 interface. Otherwise, it's the IndexerName.
1411 (Indexer.DefineMethod): If we're implementing interface indexer,
1412 set InterfaceIndexerName. Use the new Pending.IsInterfaceIndexer
1413 and Pending.ImplementIndexer methods.
1414 (Indexer.Define): Also define the PropertyBuilder if we're
1415 implementing an interface indexer and this is neither an explicit
1416 interface implementation nor do the IndexerName match the one in
1419 * pending.cs (TypeAndMethods): Added `MethodInfo [] need_proxy'.
1420 If a method is defined here, then we always need to create a proxy
1421 for it. This is used when implementing interface indexers.
1422 (Pending.IsInterfaceIndexer): New public method.
1423 (Pending.ImplementIndexer): New public method.
1424 (Pending.InterfaceMethod): Added `MethodInfo need_proxy' argument.
1425 This is used when implementing interface indexers to define a proxy
1427 (Pending.VerifyPendingMethods): Look in the `need_proxy' array and
1428 define a proxy if necessary.
1430 * interface.cs (Interface.IndexerName): New public variable.
1431 (Interface.PopulateIndexer): Set the IndexerName.
1432 (Interface.DefineIndexers): New private method. Populate all the
1433 indexers and make sure their IndexerNames match.
1435 * typemanager.cs (IndexerPropertyName): Added support for interface
1438 2002-07-22 Martin Baulig <martin@gnome.org>
1440 * codegen.cs (EmitContext.HasReturnLabel): New public variable.
1441 (EmitContext.EmitTopBlock): Always mark the ReturnLabel and emit a
1442 ret if HasReturnLabel.
1443 (EmitContext.TryCatchLevel, LoopBeginTryCatchLevel): New public
1446 * statement.cs (Do.Emit, While.Emit, For.Emit, Foreach.Emit): Save
1447 and set the ec.LoopBeginTryCatchLevel.
1448 (Try.Emit): Increment the ec.TryCatchLevel while emitting the block.
1449 (Continue.Emit): If the ec.LoopBeginTryCatchLevel is smaller than
1450 the current ec.TryCatchLevel, the branch goes out of an exception
1451 block. In this case, we need to use Leave and not Br.
1453 2002-07-22 Martin Baulig <martin@gnome.org>
1455 * statement.cs (Try.Emit): Emit an explicit ret after the end of the
1456 block unless the block does not always return or it is contained in
1457 another try { ... } catch { ... } block. Fixes bug #26506.
1458 Added verify-1.cs to the test suite.
1460 2002-07-22 Martin Baulig <martin@gnome.org>
1462 * statement.cs (Switch.TableSwitchEmit): If we don't have a default,
1463 then we do not always return. Fixes bug #24985.
1465 2002-07-22 Martin Baulig <martin@gnome.org>
1467 * expression.cs (Invocation.OverloadedResolve): Do the BetterFunction()
1468 lookup on a per-class level; ie. walk up the class hierarchy until we
1469 found at least one applicable method, then choose the best among them.
1470 Fixes bug #24463 and test-29.cs.
1472 2002-07-22 Martin Baulig <martin@gnome.org>
1474 * typemanager.cs (TypeManager.ArrayContainsMethod): Don't check the
1475 return types of the methods. The return type is not part of the
1476 signature and we must not check it to make the `new' modifier work.
1477 Fixes bug #27999, also added test-147.cs.
1478 (TypeManager.TypeToCoreType): Added TypeManager.type_type.
1480 * expression.cs (Invocation.DoResolve): Call TypeManager.TypeToCoreType()
1481 on the method's return type.
1483 2002-07-21 Martin Baulig <martin@gnome.org>
1485 * assign.cs: Make this work if the rightmost source is a constant and
1486 we need to do an implicit type conversion. Also adding a few more tests
1487 to test-38.cs which should have caught this.
1489 * makefile.gnu: Disable debugging, there's already the mcs-mono2.exe
1490 target in the makefile for this. The makefile.gnu is primarily intended
1491 for end-users who don't want to debug the compiler.
1493 2002-07-21 Martin Baulig <martin@gnome.org>
1495 * assign.cs: Improved the Assign class so it can now handle embedded
1496 assignments (X = Y = Z = something). As a side-effect this'll now also
1497 consume less local variables. test-38.cs now passes with MCS, added
1498 a few new test cases to that test.
1500 2002-07-20 Martin Baulig <martin@gnome.org>
1502 * expression.cs (Binary.EmitBranchable): Emit correct unsigned branch
1503 instructions. Fixes bug #27977, also added test-146.cs.
1505 2002-07-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1507 * cs-tokenizer.cs: fixed getHex ().
1509 2002-07-19 Martin Baulig <martin@gnome.org>
1511 * expression.cs (Invocation.EmitParams): Use TypeManager.LookupType(),
1512 not Type.GetType() to lookup the array type. This is needed when
1513 we're constructing an array of a user-defined type.
1514 (ArrayAccess.EmitDynamicInitializers): Only emit the Ldelema for
1515 single-dimensional arrays, but also for single-dimensial arrays of
1518 2002-07-19 Martin Baulig <martin@gnome.org>
1520 * expression.cs (New.DoEmit): Create a new LocalTemporary each time
1521 this function is called, it's not allowed to share LocalBuilders
1524 2002-07-19 Martin Baulig <martin@gnome.org>
1526 * expression.cs (Argument.Resolve): Report an error 118 when trying
1527 to pass a type as argument.
1529 2002-07-18 Martin Baulig <martin@gnome.org>
1531 * ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
1532 Conv_R_Un for the signed `long' type.
1534 2002-07-15 Miguel de Icaza <miguel@ximian.com>
1536 * expression.cs (MemberAccess.DoResolve): Do not reuse the field
1537 `expr' for the temporary result, as that will fail if we do
1538 multiple resolves on the same expression.
1540 2002-07-05 Miguel de Icaza <miguel@ximian.com>
1542 * ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
1543 ec.TypeContainer for looking up aliases.
1545 * class.cs (TypeContainer): Remove LookupAlias from here.
1547 * decl.cs (DeclSpace); Move here.
1549 2002-07-01 Miguel de Icaza <miguel@ximian.com>
1551 * class.cs (FindMembers): Only call filter if the constructor
1552 bulider is not null.
1554 Also handle delegates in `NestedTypes' now. Now we will perform
1555 type lookups using the standard resolution process. This also
1558 * decl.cs (DeclSpace.ResolveType): New type resolution routine.
1559 This uses Expressions (the limited kind that can be parsed by the
1560 tree) instead of strings.
1562 * expression.cs (ComposedCast.ToString): Implement, used to flag
1563 errors since now we have to render expressions.
1565 (ArrayCreation): Kill FormElementType. Use ComposedCasts in
1568 * ecore.cs (SimpleName.ToString): ditto.
1570 * cs-parser.jay: Instead of using strings to assemble types, use
1571 Expressions to assemble the type (using SimpleName, ComposedCast,
1572 MemberAccess). This should fix the type lookups in declarations,
1573 because we were using a different code path for this.
1575 * statement.cs (Block.Resolve): Continue processing statements
1576 even when there is an error.
1578 2002-07-17 Miguel de Icaza <miguel@ximian.com>
1580 * class.cs (Event.Define): Also remove the `remove' method from
1581 the list of pending items.
1583 * expression.cs (ParameterReference): Use ldarg.N (0..3) to
1584 generate more compact code.
1586 2002-07-17 Martin Baulig <martin@gnome.org>
1588 * const.cs (Const.LookupConstantValue): Add support for constant
1589 `unchecked' and `checked' expressions.
1590 Also adding test case test-140.cs for this.
1592 2002-07-17 Martin Baulig <martin@gnome.org>
1594 * statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
1595 check whether mi.ReturnType implements the IEnumerator interface; the
1596 `==' and the IsAssignableFrom() will fail in this situation.
1598 2002-07-16 Ravi Pratap <ravi@ximian.com>
1600 * ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix
1603 2002-07-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1605 * expression.cs: fixed bug #27811.
1607 2002-07-14 Miguel de Icaza <miguel@ximian.com>
1609 * expression.cs (ParameterReference.AddressOf): Patch from Paolo
1610 Molaro: when we are a ref, the value already contains a pointer
1611 value, do not take the address of it.
1613 2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1614 * removed mb-parser.jay and mb-tokenizer.cs
1616 Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
1618 * expression.cs: check against the building corlib void type.
1620 Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
1622 * ecore.cs: fix for valuetype static readonly fields: when
1623 initializing them, we need their address, not the address of a copy.
1625 Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
1627 * typemanager.cs: register also enum_type in corlib.
1629 Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
1631 * class.cs: allow calling this (but not base) initializers in structs.
1633 Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
1635 * ecore.cs: make sure we compare against the building base types
1638 Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
1640 * typemanager.cs: fix TypeToCoreType() to handle void and object
1641 (corlib gets no more typerefs after this change).
1643 2002-07-12 Miguel de Icaza <miguel@ximian.com>
1645 * expression.cs (ArrayCreation.EmitArrayArguments): use
1646 Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
1648 (ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
1649 Conv_Ovf_I_Un for the array arguments. Even if C# allows longs as
1650 array indexes, the runtime actually forbids them.
1652 * ecore.cs (ExpressionToArrayArgument): Move the conversion code
1653 for array arguments here.
1655 * expression.cs (EmitLoadOpcode): System.Char is a U2, use that
1656 instead of the default for ValueTypes.
1658 (New.DoEmit): Use IsValueType instead of
1659 IsSubclassOf (value_type)
1660 (New.DoResolve): ditto.
1661 (Invocation.EmitCall): ditto.
1663 * assign.cs (Assign): ditto.
1665 * statement.cs (Unsafe): Ok, so I got the semantics wrong.
1666 Statements *are* currently doing part of their resolution during
1669 Expressions do always resolve during resolve, but statements are
1670 only required to propagate resolution to their children.
1672 2002-07-11 Miguel de Icaza <miguel@ximian.com>
1674 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
1676 (LoadAssembly): Do not add the dll if it is already specified
1678 (MainDriver): Add the System directory to the link path at the end,
1679 after all the other -L arguments.
1681 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
1682 wrong opcode for loading bytes and bools (ldelem.i1 instead of
1683 ldelem.u1) and using the opposite for sbytes.
1685 This fixes Digger, and we can finally run it.
1687 * driver.cs (UnixParseOption): Move the option parsing here.
1688 (CSCParseOption): Implement CSC-like parsing of options.
1690 We now support both modes of operation, the old Unix way, and the
1691 new CSC-like way. This should help those who wanted to make cross
1694 The only thing broken is that /r:, /reference: and /lib: are not
1695 implemented, because I want to make those have the same semantics
1696 as the CSC compiler has, and kill once and for all the confussion
1697 around this. Will be doing this tomorrow.
1699 * statement.cs (Unsafe.Resolve): The state is checked during
1700 resolve, not emit, so we have to set the flags for IsUnsfe here.
1702 2002-07-10 Miguel de Icaza <miguel@ximian.com>
1704 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
1705 not catch the Error_ObjectRefRequired in SimpleName (as it is
1706 possible to have a class/instance variable name that later gets
1707 deambiguated), we have to check this here.
1709 2002-07-10 Ravi Pratap <ravi@ximian.com>
1711 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
1712 make static and put into Expression.
1714 (Event.Define): Register the private field of the event with the
1715 TypeManager so that GetFieldFromEvent can get at it.
1717 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
1718 keep track of the private field associated with an event which
1721 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
1724 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
1726 2002-07-10 Miguel de Icaza <miguel@ximian.com>
1728 * expression.cs (Binary.EmitBranchable): this routine emits the
1729 Binary expression in a branchable context. This basically means:
1730 we need to branch somewhere, not just get the value on the stack.
1732 This works together with Statement.EmitBoolExpression.
1734 * statement.cs (Statement.EmitBoolExpression): Use
1737 2002-07-09 Miguel de Icaza <miguel@ximian.com>
1739 * statement.cs (For): Reduce the number of jumps in loops.
1741 (For): Implement loop inversion for the For statement.
1743 (Break): We can be breaking out of a Try/Catch controlled section
1744 (foreach might have an implicit try/catch clause), so we need to
1745 use Leave instead of Br.
1747 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
1748 now). If the instace expression supports IMemoryLocation, we use
1749 the AddressOf method from the IMemoryLocation to extract the
1750 address instead of emitting the instance.
1752 This showed up with `This', as we were emitting the instance
1753 always (Emit) instead of the Address of This. Particularly
1754 interesting when This is a value type, as we dont want the Emit
1755 effect (which was to load the object).
1757 2002-07-08 Miguel de Icaza <miguel@ximian.com>
1759 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
1761 * statement.cs (Checked): Set the CheckedState during the resolve
1762 process too, as the ConvCast operations track the checked state on
1763 the resolve process, and not emit.
1765 * cs-parser.jay (namespace_member_declaration): Flag that we have
1766 found a declaration when we do. This is used to flag error 1529
1768 * driver.cs: Report ok when we display the help only.
1770 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
1772 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
1774 2002-07-04 Miguel de Icaza <miguel@ximian.com>
1776 * cs-tokenizer.cs (define): We also have to track locally the
1777 defines. AllDefines is just used for the Conditional Attribute,
1778 but we also need the local defines for the current source code.
1780 2002-07-03 Miguel de Icaza <miguel@ximian.com>
1782 * statement.cs (While, For, Do): These loops can exit through a
1783 Break statement, use this information to tell whether the
1784 statement is the last piece of code.
1786 (Break): Flag that we break.
1788 * codegen.cs (EmitContexts): New `Breaks' state variable.
1790 2002-07-03 Martin Baulig <martin@gnome.org>
1792 * class.cs (TypeContainer.MethodModifiersValid): Allow override
1793 modifiers in method declarations in structs. Otherwise, you won't
1794 be able to override things like Object.Equals().
1796 2002-07-02 Miguel de Icaza <miguel@ximian.com>
1798 * class.cs (Method, Property, Indexer): Do not allow the public
1799 modifier to be used in explicit interface implementations.
1801 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
1802 override modifiers in method declarations in structs
1804 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
1806 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
1807 integer or real overflow, report an error
1809 2002-07-02 Martin Baulig <martin@gnome.org>
1811 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
1812 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
1813 to tell the runtime about our newly created System.Object and
1814 System.ValueType types.
1816 2002-07-02 Miguel de Icaza <miguel@ximian.com>
1818 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
1819 struct instead of Ldarg/Starg.
1821 2002-07-02 Martin Baulig <martin@gnome.org>
1823 * expression.cs (Indirection.Indirection): Call
1824 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
1826 2002-07-02 Martin Baulig <martin@gnome.org>
1828 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
1829 ValueType, call TypeManager.TypeToCoreType() on it.
1830 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
1831 the OpCodes.Newarr argument.
1833 2002-07-02 Martin Baulig <martin@gnome.org>
1835 * expression.cs (Invocation.EmitCall): When compiling corlib,
1836 replace all calls to the system's System.Array type to calls to
1837 the newly created one.
1839 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
1840 System.Array methods.
1841 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
1842 from the system's System.Array type which must be replaced.
1844 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
1846 * typemanager.cs: load unverifiable_code_ctor so we can build
1847 corlib using the correct type. Avoid using GetTypeCode() with
1849 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
1850 TypeManager.object_type to allow building corlib.
1852 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
1854 * ecore.cs: handle System.Enum separately in LoadFromPtr().
1856 2002-07-01 Martin Baulig <martin@gnome.org>
1858 * class.cs: Make the last change actually work, we need to check
1859 whether `ifaces != null' to avoid a crash.
1861 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
1863 * class.cs: when we build structs without fields that implement
1864 interfaces, we need to add the interfaces separately, since there is
1865 no API to both set the size and add the interfaces at type creation
1868 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
1870 * expression.cs: the dimension arguments to the array constructors
1871 need to be converted if they are a long.
1873 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
1875 * class.cs: don't emit ldarg.0 if there is no parent constructor
1876 (fixes showstopper for corlib).
1878 2002-06-29 Martin Baulig <martin@gnome.org>
1880 MCS now compiles corlib on GNU/Linux :-)
1882 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
1883 ie. check for MethodImplOptions.InternalCall.
1885 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
1886 and TypeManager.attribute_type are null, so we must explicitly check
1887 whether parent is not null to find out whether it's an attribute type.
1888 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
1889 and SetBuilder, not only if the property is neither abstract nor external.
1890 This is necessary to set the MethodImplOptions on the accessor methods.
1891 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
1892 SetBuilder, see Property.Emit().
1894 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
1895 populate "System.Object", "System.ValueType" and "System.Attribute" since
1896 they've already been populated from BootCorlib_PopulateCoreTypes().
1898 2002-06-29 Martin Baulig <martin@gnome.org>
1900 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
1901 is the NullLiteral, we also need to make sure that target_type is not
1904 2002-06-29 Martin Baulig <martin@gnome.org>
1906 * rootcontext.cs (RootContext.ResolveCore): We must initialize
1907 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
1908 before calling BootstrapCorlib_ResolveDelegate ().
1910 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1912 * statement.cs: fixed build-breaker. All tests passed ok.
1914 2002-06-27 Martin Baulig <martin@gnome.org>
1916 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
1917 for System.Decimal when compiling corlib.
1919 2002-06-27 Martin Baulig <martin@gnome.org>
1921 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
1922 switch blocks which contain nothing but a default clause.
1924 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
1926 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
1928 2002-06-27 Martin Baulig <martin@gnome.org>
1930 * ecore.cs (PropertyExpr.PropertyExpr): Call
1931 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
1933 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
1934 is already a TypeBuilder.
1936 2002-06-27 Martin Baulig <martin@gnome.org>
1938 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
1939 `target_type == TypeManager.array_type', not IsAssignableFrom() in
1940 the "from an array-type to System.Array" case. This makes it work
1941 when compiling corlib.
1943 2002-06-27 Martin Baulig <martin@gnome.org>
1945 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
1946 non-static PropertyExpr, set its InstanceExpression. This makes
1947 the `ICollection.Count' property work in System/Array.cs.
1949 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
1951 * driver.cs: Made error handling more consistent. Errors now
1952 tracked by Report class, so many methods which used to return int
1953 now return void. Main() now prints success/failure and
1954 errors/warnings message.
1956 Renamed '--probe' compiler argument to '--expect-error'. Removed
1957 the magic number return values (123 and 124). Now, if the
1958 expected error occurs, the compiler exits with success (exit value
1959 0). If the compilation completes without seeing that particular
1960 error, the compiler exits with failure (exit value 1). The
1961 makefile in mcs/errors has been changed to handle the new behaviour.
1963 * report.cs: Made 'expected error' number a property and renamed
1964 it from 'Probe' to 'ExpectedError'.
1966 * genericparser.cs: Removed error handling support, since it is
1967 now all done by Report class.
1969 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
1970 class, so parse() no longer returns an int.
1972 * namespace.cs: Use Report.Error instead of GenericParser.error
1974 2002-06-22 Miguel de Icaza <miguel@ximian.com>
1976 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
1977 TypeContainer.AddOperator): At the front of the list put the
1978 explicit implementations, so they get resolved/defined first.
1980 2002-06-21 Miguel de Icaza <miguel@ximian.com>
1982 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
1983 interface type is implemented by this TypeContainer. Used during
1984 explicit interface implementation.
1986 (Property.Define, Indexer.Define, Method.Define): Validate that
1987 the given interface in the explicit implementation is one of the
1988 base classes for the containing type.
1990 Also if we are explicitly implementing an interface, but there is
1991 no match in the pending implementation table, report an error.
1993 (Property.Define): Only define the property if we are
1994 not explicitly implementing a property from an interface. Use the
1995 correct name also for those properties (the same CSC uses,
1996 although that is really not needed).
1998 (Property.Emit): Do not emit attributes for explicitly implemented
1999 properties, as there is no TypeBuilder.
2001 (Indexer.Emit): ditto.
2003 Hiding then means that we do not really *implement* a pending
2004 implementation, which makes code fail.
2006 2002-06-22 Martin Baulig <martin@gnome.org>
2008 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
2009 the return value of Object.GetType(). [FIXME: we need to do this whenever
2010 we get a type back from the reflection library].
2012 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
2014 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
2016 2002-06-20 Miguel de Icaza <miguel@ximian.com>
2018 * attribute.cs: Return null if we can not look up the type.
2020 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
2021 the interface types found.
2023 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
2024 interface types found.
2026 * typemanager.cs (GetInterfaces): Make this routine returns alll
2027 the interfaces and work around the lame differences between
2028 System.Type and System.Reflection.Emit.TypeBuilder in the results
2029 result for GetInterfaces.
2031 (ExpandInterfaces): Given an array of interface types, expand and
2032 eliminate repeated ocurrences of an interface. This expands in
2033 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
2036 2002-06-21 Martin Baulig <martin@gnome.org>
2038 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
2041 2002-06-21 Martin Baulig <martin@gnome.org>
2043 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
2044 and called with one of the core types, return the corresponding typebuilder for
2047 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
2050 2002-06-21 Martin Baulig <martin@gnome.org>
2052 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
2053 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
2054 (Expression.ConvertReferenceExplicit): Likewise.
2056 * expression.cs (ElementAccess.DoResolve): Likewise.
2057 (ElementAccess.DoResolveLValue): Likewise.
2059 2002-06-10 Martin Baulig <martin@gnome.org>
2061 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
2062 add the "value" parameter to the parameter list.
2064 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
2067 2002-06-19 Miguel de Icaza <miguel@ximian.com>
2069 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
2070 the argument to an int, uint, long or ulong, per the spec. Also
2071 catch negative constants in array creation.
2073 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
2075 * class.cs: do not allow the same interface to appear twice in
2076 the definition list.
2078 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
2080 * ecore.cs: don't use ldlen with System.Array.
2082 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
2084 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
2086 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
2088 * modifiers.cs: produce correct field attributes for protected
2089 internal. Easy fix so miguel can work on ther harder stuff:-)
2091 2002-06-18 Miguel de Icaza <miguel@ximian.com>
2093 * pending.cs: New file. Move the code from class.cs here.
2094 Support clearning the pending flag for all methods (when not doing
2095 explicit interface implementation).
2097 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
2099 * rootcontext.cs: added a couple more types needed to bootstrap.
2101 2002-06-17 Miguel de Icaza <miguel@ximian.com>
2103 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
2104 constructor in the type, instead of any constructor in the type
2105 hierarchy. Thanks to Paolo for finding this bug (it showed up as
2106 a bug in the Mono runtime when applying the params attribute).
2108 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
2109 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
2111 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
2113 * expression.cs (Unary.ResolveOperator): Use TypeManager
2114 to resolve the type.
2116 2002-06-13 Ravi Pratap <ravi@ximian.com>
2118 * cs-parser.jay (enum_member_declaration): Pass in the attributes
2121 * enum.cs (AddEnumMember): Add support to store the attributes associated
2122 with each member too.
2124 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
2125 field builders too - this takes care of the enum member case.
2127 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
2129 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
2130 address-of operator on both value types and pointers.
2132 2002-06-10 Martin Baulig <martin@gnome.org>
2134 * interface.cs (Interface.PopulateIndexer): Add the indexer's
2135 PropertyBuilder to the `property_builders' list.
2137 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
2138 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
2139 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
2140 find any indexers which are inherited from an interface.
2142 2002-06-09 Martin Baulig <martin@gnome.org>
2144 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
2145 the same type as the constant if necessary. There's also a test-130.cs
2148 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
2150 * typemanager.cs (TypeManager.ChangeType): Previously known as
2151 Enum.ChangeEnumType().
2153 2002-06-09 Martin Baulig <martin@gnome.org>
2155 * expression.cs (Cast.TryReduce): Added support for consts.
2157 2002-06-08 Ravi Pratap <ravi@ximian.com>
2159 * class.cs (Accessor): Hold attributes information so we can pass
2162 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
2163 Modify to pass in attributes attached to the methods.
2165 (add_accessor_declaration, remove_accessor_declaration): Ditto.
2167 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
2168 to handle the Accessor kind :-)
2170 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
2172 2002-06-08 Martin Baulig <martin@gnome.org>
2174 * expression.cs (Unary.TryReduceNegative): Added support for
2177 2002-06-08 Martin Baulig <martin@gnome.org>
2179 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
2180 name can't be found in the `defined_names' - the caller will do a
2181 MemberLookup in this case and thus find methods in System.Enum
2182 such as Enum.IsDefined().
2184 2002-06-08 Martin Baulig <martin@gnome.org>
2186 * enum.cs (Enum.ChangeEnumType): This is a custom version of
2187 Convert.ChangeType() which works with TypeBuilder created types.
2188 (Enum.LookupEnumValue, Enum.Define): Use it here.
2190 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
2191 `TypeBuilder.BaseType != null' check.
2192 (TypeContainer.FindMembers): Only lookup parent members if we
2193 actually have a parent.
2194 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
2195 (ConstructorInitializer.Resolve): Likewise.
2197 * interface.cs (Interface.FindMembers): Added
2198 `TypeBuilder.BaseType != null' check.
2200 * rootcontext.cs (RootContext.ResolveCore): Added
2201 "System.Runtime.CompilerServices.IndexerNameAttribute" to
2202 classes_second_stage.
2204 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
2205 debug_type and trace_type when compiling with --nostdlib.
2207 2002-06-07 Martin Baulig <martin@gnome.org>
2209 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
2210 (AddField): Set it to true when adding a non-static field.
2211 (DefineType): Use `have_nonstatic_fields' to find out whether we
2212 have non-static fields, not `Fields != null'.
2214 2002-06-02 Miguel de Icaza <miguel@ximian.com>
2216 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
2217 dereferencing a null on the static-field code path)
2219 2002-05-30 Martin Baulig <martin@gnome.org>
2221 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
2222 to take command line arguments. Use reflection to call the new
2223 custom `Initialize' function on the symbol writer and pass it the
2224 command line arguments.
2226 * driver.cs (--debug-args): New command line argument to pass command
2227 line arguments to the symbol writer.
2229 2002-05-28 Miguel de Icaza <miguel@ximian.com>
2231 * assign.cs (DoResolve): Forgot to do the implicit conversion to
2232 the target type for indexers and properties. Thanks to Joe for
2235 2002-05-27 Miguel de Icaza <miguel@ximian.com>
2237 * typemanager.cs (MethodFlags): returns the method flags
2238 (Obsolete/ShouldIgnore) that control warning emission and whether
2239 the invocation should be made, or ignored.
2241 * expression.cs (Invocation.Emit): Remove previous hack, we should
2242 not do this on matching a base type, we should do this based on an attribute
2244 Only emit calls to System.Diagnostics.Debug and
2245 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
2246 on the command line.
2248 * rootcontext.cs: Global settings for tracing and debugging.
2250 * cs-tokenizer.cs (define): New utility function to track
2251 defines. Set the global settings for TRACE and DEBUG if found.
2253 2002-05-25 Ravi Pratap <ravi@ximian.com>
2255 * interface.cs (Populate*): Pass in the TypeContainer as well as
2256 the DeclSpace as parameters so that we can create EmitContexts and
2257 then use that to apply attributes etc.
2259 (PopulateMethod, PopulateEvent, PopulateProperty)
2260 (PopulateIndexer): Apply attributes everywhere.
2262 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
2265 (ApplyAttributes): Update accordingly.
2267 We now apply interface attributes for all members too.
2269 2002-05-26 Miguel de Icaza <miguel@ximian.com>
2271 * class.cs (Indexer.Define); Correctly check if we are explicit
2272 implementation (instead of checking the Name for a ".", we
2273 directly look up if the InterfaceType was specified).
2275 Delay the creation of the PropertyBuilder.
2277 Only create the PropertyBuilder if we are not an explicit
2278 interface implementation. This means that explicit interface
2279 implementation members do not participate in regular function
2280 lookups, and hence fixes another major ambiguity problem in
2281 overload resolution (that was the visible effect).
2283 (DefineMethod): Return whether we are doing an interface
2286 * typemanager.cs: Temporary hack until we get attributes in
2287 interfaces (Ravi is working on that) and we get IndexerName
2288 support in interfaces.
2290 * interface.cs: Register the indexers as properties.
2292 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
2293 warning, I have verified that this is a bug in the .NET runtime
2294 (JavaScript suffers of the same problem).
2296 * typemanager.cs (MemberLookup): When looking up members for
2297 interfaces, the parent of an interface is the implicit
2298 System.Object (so we succeed in searches of Object methods in an
2299 interface method invocation. Example: IEnumerable x; x.ToString
2302 2002-05-25 Miguel de Icaza <miguel@ximian.com>
2304 * class.cs (Event): Events should also register if they do
2305 implement the methods that an interface requires.
2307 * typemanager.cs (MemberLookup); use the new GetInterfaces
2310 (GetInterfaces): The code used to lookup interfaces for a type is
2311 used in more than one place, factor it here.
2313 * driver.cs: Track the errors at the bottom of the file, we kept
2316 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
2317 instance if the method we are calling is static!
2319 2002-05-24 Miguel de Icaza <miguel@ximian.com>
2321 * attribute.cs (ApplyAttributes): Make this function filter out
2322 the IndexerName attribute (as that attribute in reality is never
2323 applied) and return the string constant for the IndexerName
2326 * class.cs (TypeContainer.Emit): Validate that all the indexers
2327 have the same IndexerName attribute, and if so, set the
2328 DefaultName attribute on the class.
2330 * typemanager.cs: The return value might contain other stuff (not
2331 only methods). For instance, consider a method with an "Item"
2332 property and an Item method.
2334 * class.cs: If there is a problem with the parameter types,
2337 2002-05-24 Ravi Pratap <ravi@ximian.com>
2339 * ecore.cs (ImplicitConversionExists): Wrapper function which also
2340 looks at user defined conversion after making a call to
2341 StandardConversionExists - we need this for overload resolution.
2343 * expression.cs : Update accordingly the various method calls.
2345 This fixes 2 bugs filed against implicit user defined conversions
2347 2002-05-22 Miguel de Icaza <miguel@ximian.com>
2349 * statement.cs: Track the result of the assignment.
2351 2002-05-21 Miguel de Icaza <miguel@ximian.com>
2353 * expression.cs (MemberAccess): Improved error reporting for
2354 inaccessible members.
2356 2002-05-22 Martin Baulig <martin@gnome.org>
2358 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
2359 itself with debugging support.
2361 2002-05-22 Martin Baulig <martin@gnome.org>
2363 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
2364 Removed, this isn't needed anymore.
2366 2002-05-20 Martin Baulig <martin@gnome.org>
2368 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
2369 be underlying type for an enum.
2371 2002-05-20 Miguel de Icaza <miguel@ximian.com>
2373 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
2374 that splits out the loading of just the core types.
2376 * rootcontext.cs (ResolveCore): Split the struct resolution in
2377 two, so we can load the enumeration underlying types before any
2380 * expression.cs (Is): Bandaid until we fix properly Switch (see
2381 bug #24985 for details).
2383 * typemanager.cs (ImplementsInterface): The hashtable will contain
2384 a null if there are no interfaces implemented.
2386 2002-05-18 Miguel de Icaza <miguel@ximian.com>
2388 * cs-parser.jay (indexer_declarator): It is fine to have array
2391 2002-05-17 Miguel de Icaza <miguel@ximian.com>
2393 * typemanager.cs: (RegisterBuilder): New function used to register
2394 TypeBuilders that implement interfaces. Since
2395 TypeBuilder.GetInterfaces (as usual) does not work with lame
2397 (AddUserType): register interfaces.
2399 (ImplementsInterface): Use the builder_to_ifaces hash if we are
2400 dealing with TypeBuilder. Also, arrays are showing up as
2401 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
2402 methods can not be invoked on them!
2404 * ecore.cs (ExplicitReferenceConversionExists): Made public.
2405 (ImplicitReferenceConversionExists): Split out from
2406 StandardConversionExists.
2408 * expression.cs (As): We were only implementing one of the three
2409 cases for the as operator. We now implement them all.
2410 (Is): Implement the various other cases for Is as well.
2412 * typemanager.cs (CACHE): New define used to control if we want or
2413 not the FindMembers cache. Seems to have a negative impact on
2414 performance currently
2416 (MemberLookup): Nested types have full acess to
2417 enclosing type members
2419 Remove code that coped with instance/static returns for events, we
2420 now catch this in RealFindMembers.
2422 (RealFindMembers): only perform static lookup if the instance
2423 lookup did not return a type or an event.
2425 2002-05-17 Miguel de Icaza <miguel@ximian.com>
2427 * assign.cs (CompoundAssign): We pass more semantic information
2428 now to Compound Assignments than we did before: now we have all
2429 the information at hand, and now we resolve the target *before* we
2430 do the expression expansion, which allows the "CacheValue" method
2431 to have the effect we intended (before, a [x] += 1 would generate
2432 two differen ArrayAccess expressions from the ElementAccess,
2433 during the resolution process).
2435 (CompoundAssign.DoResolve): Resolve target and original_source here.
2437 2002-05-16 Miguel de Icaza <miguel@ximian.com>
2439 * expression.cs (ArrayAccess): dropped debugging information.
2441 * typemanager.cs: Small bug fix: I was always returning i_members,
2442 instead of one of i_members or s_members (depending on which had
2445 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
2446 method is invoked before any code generation takes place, and it
2447 is a mechanism to inform that the expression will be invoked more
2448 than once, and that the method should use temporary values to
2449 avoid having side effects
2451 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
2453 * ecore.cs (Expression.CacheTemporaries): Provide empty default
2456 * expression.cs (Indirection, ArrayAccess): Add support for
2457 CacheTemporaries in these two bad boys.
2459 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
2461 (StoreFromPtr): Handle stobj as well.
2463 * expression.cs (UnaryMutator): Share more code.
2465 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
2466 down: I was not tracking the Filter function as well, which
2467 was affecting the results of the cache.
2469 2002-05-15 Miguel de Icaza <miguel@ximian.com>
2471 * attribute.cs: Remove the hack to handle the CharSet property on
2474 2002-05-14 Miguel de Icaza <miguel@ximian.com>
2476 * attribute.cs (DoResolve): More uglyness, we now only try to
2477 resolve the attribute partially, to extract the CharSet
2478 information (only if we are a StructLayout attribute). Otherwise
2480 (GetExtraTypeInfo): Add some code to conditionally kill in the
2481 future this. I am more and more convinced that the .NET
2482 framework has special code to handle the attribute setting on
2485 * expression.cs (IsParamsMethodApplicable): Revert my previous
2486 foreach change here, it was wrong.
2488 2002-05-13 Miguel de Icaza <miguel@ximian.com>
2490 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
2491 (pp_expr): do not abort on unknown input, just return.
2492 (eval): abort if there are pending chars.
2494 * attribute.cs (Attribute.Resolve): Positional parameters are
2495 optional. Deal with that case.
2497 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
2498 the Ansi/Unicode/Auto information for the type.
2500 (TypeContainer.DefineType): instantiate the EmitContext here, as
2501 we will be using it during the type definition (to resolve
2502 attributes) and during the emit phase.
2504 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
2505 to pull type information out of the attributes
2507 (Attribute.Resolve): track the constructor builder, and allow for
2508 multiple invocations (structs and classes will use this).
2510 * ecore.cs (MemberLookupFinal): new version with all the
2511 parameters customizable.
2513 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
2514 constructors. Return if the result value is null (as the error
2515 would have been flagged already by MemberLookupFinal)
2517 Do not allow instances of abstract classes or interfaces to be
2520 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
2521 We have to compare the assembly property here when dealing with
2522 FamANDAssem and Assembly access modifiers, because we might be
2523 creating an assembly from *modules* (that means that we are not
2524 getting TypeBuilders for types defined in other modules that are
2525 part of this assembly).
2527 (Method.Emit): If the method is marked abstract and has a body,
2530 (TypeContainer.DefineMembers): If both the defined member and the
2531 parent name match are methods, then do not emit any warnings: let
2532 the Method.Define routine take care of flagging warnings. But if
2533 there is a mismatch (method overrides something else, or method is
2534 overriwritten by something, then emit warning).
2536 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
2537 set to null, this means `do not check for the return type on the
2540 (Method.Define): set the return type for the method signature to
2541 null, so that we get methods with the same name and parameters and
2542 different return types. This is used to flag warning 114 (you are
2543 hiding a method, and you probably want to use the new/override
2546 * typemanager.cs (MemberLookup): Implemented proper access
2547 control, closing a long standing set of bug reports. The problem
2548 was that the Framework only has two bits: Public and NonPublic,
2549 and NonPublic includes private and protected methods, but we need
2550 to enforce the FamANDAssem, FamOrAssem and Family.
2552 2002-05-11 Miguel de Icaza <miguel@ximian.com>
2554 * statement.cs (GotoCase): Return true: Ammounts to giving up
2555 knowledge on whether we return or not, and letting the other case
2556 be responsible for it.
2558 2002-05-10 Miguel de Icaza <miguel@ximian.com>
2560 * driver.cs: Do not load directories for each file processed, only
2561 do it if there is a pattern.
2563 * ecore.cs: Report readonly assigns here as well, as we might have
2564 been resolved only by MemberAccess.
2566 (SimpleName.SimpleNameResolve): Also be useful for LValue
2567 resolution. We need this to propagate assign to local readonly variables
2569 * typemanager.cs: Use a ptrhashtable for the criteria, because we
2570 do not want to reuse potential criteria memory.
2572 * class.cs (MyEventBuilder): Set reflected_type;
2574 * ecore.cs (Constantify): Added support for constifying bools.
2576 (RootContext.LookupType): Added a cache for values looked up in
2577 the declaration space.
2579 * typemanager.cs (FindMembers): Now is a front-end to
2580 RealFindMembers, and provides a two-level hashtable-based cache to
2583 15% performance improvement: from 22.5 to 19.2 seconds.
2585 * expression.cs (IsParamsMethodApplicable): use foreach.
2586 (Invocation.DoResolve): ditto.
2587 (New.DoResolve): ditto.
2588 (ArrayCreation.DoResolve): ditto.
2590 * ecore.cs (FindMostEncompassingType): use foreach.
2592 * delegate.cs (NewDelegate.DoResolve): Use foreach
2594 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
2595 (RemoveMethods): use foreach.
2597 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
2598 nested foreach statements instead of for, and also break out of
2599 the inner loop once a match is found.
2601 (Invocation.OverloadResolve): Use foreach, simplify the code.
2603 2002-05-08 Miguel de Icaza <miguel@ximian.com>
2605 * cfold.cs (BinaryFold): During an enumeration evaluation context,
2606 we actually unwrap the expression to allow for extra information
2609 * expression.cs: Use Shr_Un on unsigned operations.
2611 2002-05-08 Ravi Pratap <ravi@ximian.com>
2613 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
2614 applicable operators was not being considered correctly. This closes
2615 the bug Miguel reported.
2617 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
2619 * attribute.cs: check that the type derives from System.Attribute
2620 and report the correct error in that case (moved the duplicate code to
2621 its own method, too).
2623 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
2625 * attribute.cs: lookup attribute type name as the spec says: first the
2626 bare attribute name and then name + "Attribute" (nant compiles with
2627 mcs after this fix).
2629 2002-05-07 Miguel de Icaza <miguel@ximian.com>
2631 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
2632 Because of the way we parse things, we should try to see if a
2633 UIntConstant can fit in an integer.
2635 2002-05-07 Ravi Pratap <ravi@ximian.com>
2637 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
2638 when we are in an explicit context.
2640 (ConvertReferenceExplicit): When converting from Iface type S to Class
2641 T make sure the rules are implemented as an OR.
2643 * parameter.cs (ParameterType): Make it a property for now although the
2644 purpose really isn't anything immediate.
2646 * expression.cs (Is*Applicable): Do better checking on the parameter type
2647 of a ref/out parameter. The ones from the system assemblies are already
2648 marked with the correct type so we don't need to do any correction.
2650 * ecore.cs (StandardConversionExists): Conversion from Interface types to
2651 the object type is standard too so include that.
2653 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2655 * ecore.cs (StandardConversionExists): Augment with missing code:
2656 deal with IntConstant, LongConstants and Enumerations.
2658 * assign.cs: Report the error, instead of failing silently
2660 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
2661 typecontainer that they are declared, because the
2662 typecontainer/namespace will have the list of using clauses that
2665 Assembly Attributes were escaping the normal registration
2668 (EmitCode): Apply attributes within an EmitContext that represents
2669 the container they were declared on.
2671 * cs-parser.jay: Track bases for structs. How did I get this wrong?
2673 2002-05-06 Ravi Pratap <ravi@ximian.com>
2675 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
2676 Revamp completely - make much cleaner as we now operate only
2679 (FindMostSpecificSource, FindMostSpecificTarget): New methods
2680 to implement the logic detailed in the spec more correctly.
2682 (UserDefinedConversion): Update accordingly.
2684 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2686 * statement.cs: Return flow analysis information up.
2688 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
2691 (token): Do not consume an extra character before calling
2694 2002-05-06 Piers Haken <piersh@friskit.com>
2696 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
2698 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2700 * class.cs (Constructor.Emit): Set the IsStatic flag in the
2701 EmitContext during the instance constructor initializer
2702 resolution, to stop access to instance variables.
2704 This is mandated by the spec, last paragraph of the `constructor
2705 initializers' section.
2707 2002-05-05 Miguel de Icaza <miguel@ximian.com>
2709 * cs-parser.jay, class.cs (Accessor): new class used to represent
2710 an accessor (get or set). In the past we used `null' to represent
2711 a missing accessor. But this is ambiguous because there was no
2712 way to tell in abstract indexers/properties if one of them was
2715 Now there is a way of addressing that.
2717 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
2718 instead of FindMembers.
2720 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
2721 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
2723 * attribute.cs: Treat indexers and properties as the same in terms
2724 of applying attributes
2726 * ecore.cs (FindMostEncompassedType): Use statically initialized
2727 EmptyExpressions()s like we do elsewhere to avoid creating useless
2728 objects (and we take this out of the tight loop).
2730 (GetConversionOperators): Move the code to extract the actual
2731 operators to a separate routine to clean things up.
2733 2002-05-04 Miguel de Icaza <miguel@ximian.com>
2735 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
2736 events are always registered FieldBuilders.
2738 * class.cs (FieldBase): New class shared by Fields
2740 * delegate.cs: If we are a toplevel delegate, use our full name.
2741 If we are a nested delegate, then only use our tail name.
2743 2002-05-02 Ravi Pratap <ravi@ximian.com>
2745 * expression.cs (IsApplicable): Ensure that we add the "&" to
2746 ref/out types before comparing it with the type of the argument.
2748 (IsParamsMethodApplicable): Ditto.
2750 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
2753 * delegate.cs : Handle the case when we have more than one applicable
2754 method. Flag an error only when we finish checking all.
2756 2002-05-02 Miguel de Icaza <miguel@ximian.com>
2758 * expression.cs: Add support for boolean static initializers.
2760 2002-05-01 Miguel de Icaza <miguel@ximian.com>
2762 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
2764 * parameter.cs (ComputeParameterTypes,
2765 ComputeAndDefineParameterTypes): Better error handling: now we
2766 clear the `types' cache if we fail during any of the type lookups.
2767 We also return the status code correctly to our caller
2769 * delegate.cs: If we fail to define a delegate, abort the extra
2772 * expression.cs (Binary.ResolveOperator): for
2773 operator==(object,object) and operator !=(object, object) we also
2774 have to verify that there is an implicit conversion from one to
2777 (ArrayAccess.DoResolve): Array Access can operate on
2780 2002-04-30 Miguel de Icaza <miguel@ximian.com>
2782 * assign.cs (CompoundAssign): A new class used as a "flag" that
2783 the assignment actually is happening as part of a compound
2784 assignment operator.
2786 During compound assignment, a few new rules exist to enable things
2793 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
2794 to the type of x) if y is implicitly convertible to the type of x,
2795 and the operator is a builtin operator and the return type of the
2796 operator is explicitly convertible to the type of x.
2798 * rootcontext.cs: Reset warning level to 2. 4 catches various
2799 "interesting" features in mcs, we must clean this up at some
2800 point, but currently am trying to kill other bugs ;-)
2802 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
2803 in container classes as well.
2805 * expression.cs (Binary.ResolveOperator): Handle string case
2806 before anything else (as operator overloading does emit an error
2807 before doing anything else).
2809 This code could go away when we move to a table driven model, but
2810 i could not come up with a good plan last night.
2812 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
2814 * typemanager.cs (CSharpName): reimplementation using regex.
2815 * class.cs: added null check for fields in Emit
2816 * rootcontext.cs: set warninglevel to 4
2818 2002-04-29 Miguel de Icaza <miguel@ximian.com>
2820 * typemanager.cs (CSharpName): reimplemented with Lupus
2823 2002-04-28 Miguel de Icaza <miguel@ximian.com>
2825 * statement.cs (If): correclty implement Resolve, because we were
2826 not catching sem errors in there. The same process is needed
2828 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
2831 (Statement.Warning_DeadCodeFound): Factorize code.
2832 (While): Report dead code here too.
2834 (Statement): Added Resolve virtual method to allow
2835 for resolution split from the emit code.
2837 2002-04-26 Miguel de Icaza <miguel@ximian.com>
2839 * statement.cs (EmitBoolExpression): No longer try to resolve the
2841 (MakeBoolean): New utility function that resolve, implicitly
2842 converts to boolean and tags the expression.
2845 (If, Do): Implement dead code elimination.
2846 (While): Implement loop inversion
2848 (Do, While, For, If): Resolve the expression prior to calling our
2851 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
2854 - added method Report28 (warning: program has more than one entry point)
2855 - added method IsEntryPoint, implements paragraph 10.1 of the spec
2856 - modified method Method.Define, the part at the end of the method
2858 * rootcontext.cs: added static public Location EntryPointLocation;
2860 * ../errors/cs0028.cs : Add test case for the above warning.
2863 - modified method CSharpName to allow arrays of primitive type to
2864 be printed nicely (e.g. instead of System.Int32[][] it now prints
2866 - added method CSharpSignature: returns the signature of a method
2867 in string format to be used in reporting errors, warnings, etc.
2869 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
2872 2002-04-26 Ravi Pratap <ravi@ximian.com>
2874 * delegate.cs (Define): Fix extremely silly bug where I was
2875 setting the type of the 'object' parameter of the BeginInvoke
2876 method to System.IAsyncResult instead of System.Object ;-)
2878 2002-04-26 Miguel de Icaza <miguel@ximian.com>
2880 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
2883 (Constructor.Emit): return if we fail to initialize the
2884 constructor. Another door closed!
2886 * expression.cs (New.DoResolve): Improve error message (from -6 to
2887 1501). Use DeclaredOnly lookup to find the exact constructor.
2889 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
2890 loop. This is useful.
2892 * cs-parser.jay: Adjust the default parameters so that destructors
2893 have the proper signature.
2895 2002-04-26 Martin Baulig <martin@gnome.org>
2897 * driver.cs (LoadAssembly): If `assembly' contains any characters
2898 which are only valid in path names and not in assembly names
2899 (currently slash, backslash and point), use Assembly.LoadFrom ()
2900 instead of Assembly.Load () on the `assembly' (before iteration
2901 over the link_paths).
2903 2002-04-26 Martin Baulig <martin@gnome.org>
2905 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
2907 2002-04-25 Miguel de Icaza <miguel@ximian.com>
2909 * class.cs (Property): use the new typemanager.MemberLookup
2911 (TypeContainer.MemberLookup): Implement using the
2912 TypeManager.MemberLookup now.
2914 * typemanager.cs: Make MemberLookup a function of the TypeManager,
2915 and return MemberInfos, so that these can be used without an
2916 EmitContext (what we had before).
2918 2002-04-24 Miguel de Icaza <miguel@ximian.com>
2920 * expression.cs: Fix the case where the argument to params if the
2921 type of the params. I omitted handling this before. Fixed
2923 2002-04-22 Miguel de Icaza <miguel@ximian.com>
2925 * driver.cs: Call BootCorlib_PopulateCoreType
2927 * class.cs (Property.CheckBase): Check for properties only, not
2930 * interface.cs: Temporary hack: try/catch around the
2931 CustomAttributeBuilder, because I am getting an exception that I
2934 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
2935 types whose definitions are required to be there (attributes are
2936 defined before standard types).
2938 Compute definitions as we boot the various types, as they are used
2939 immediately (value_type class will need object_type, but if we do
2940 not initialize object_type, we will pass a null, which will let
2941 the runtime pick the System.Object from the existing corlib, which
2942 is not what we want).
2944 2002-04-22 Patrik Torstensson <totte@labs2.com>
2946 * cs-tokenizer.cs: fixed a number of trim() issues.
2948 2002-04-22 Ravi Pratap <ravi@ximian.com>
2950 * expression.cs (Argument.Type): Ensure that we return the correct
2951 type when we have out or ref parameters [in which case we
2954 2002-04-22 Miguel de Icaza <miguel@ximian.com>
2956 * class.cs (Property, Indexer): Allow extern modifier in there.
2958 * typemanager.cs (InitBaseTypes): Initializes object_type and
2959 value_type, since those will be used early on during the bootstrap
2960 process to compile corlib.
2962 (InitCoreTypes): Move code from here to InitBaseTypes.
2964 2002-04-21 Miguel de Icaza <miguel@ximian.com>
2966 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
2967 single-dimension arrays as using the ldlen opcode.
2969 Daniel Lewis discovered this optimization.
2971 * typemanager.cs: Add signature for System.Array::get_Length
2973 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2975 * statement.cs: report the error when the foreach does not apply to an
2976 array nor a collection.
2978 2002-04-19 Miguel de Icaza <miguel@ximian.com>
2980 * expression.cs: Add implicit conversions to the operator ~.
2982 * constant.cs (DecimalConstant.Emit): Emit decimal value.
2984 * typemanager.cs: Locate the decimal constructor.
2986 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2988 * attribute.cs: use the new property of TypeOf.
2989 * expression.cs: added 'get' property around typearg.
2991 These changes fix a build breaker reported by NickD. Is this the
2992 correct way to fix? If not, please, revert my changes and make it
2995 2002-04-17 Miguel de Icaza <miguel@ximian.com>
2997 * attribute.cs: Add support for typeof in attribute invocations.
2998 I am not sure that this is right though.
3000 2002-04-14 Duncan Mak <duncan@ximian.com>
3002 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
3003 Binary.Operator.Division case.
3005 2002-04-13 Ravi Pratap <ravi@ximian.com>
3007 * class.cs (DefineType): Ensure that we do a proper check on
3008 attribute types and also register it with the TypeManager.
3010 (TypeContainer.Targets): The default for attribute types is
3011 AttributeTargets.All.
3013 * attribute.cs (ApplyAttributes): Registering the attribute type
3014 is done elsewhere, not when we discover we have a Usage attribute.
3016 2002-04-12 Ravi Pratap <ravi@ximian.com>
3018 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
3019 and get rid of is_delegate parameter.
3021 * everywhere : update.
3023 2002-04-12 Ravi Pratap <ravi@ximian.com>
3025 * cs-parser.jay (compilation_unit): Revamp completely to use
3026 some new ideas that I got from Rhys' grammar to solve the problems
3027 with assembly level attributes.
3029 (outer_declaration): New grammar production.
3031 (attribute_sections): Add.
3033 (opt_attributes): Base on attribute_sections
3035 (namespace_declaration): Allow opt_attributes to tackle the case
3036 when we have assembly level attributes - we are clever in this
3039 * attribute.cs (ApplyAttributes): Do not worry about assembly
3040 attributes in the non-global context.
3042 * rootcontext.cs (AddGlobalAttributes): Go back to using this
3043 instead of SetGlobalAttributes.
3045 * class.cs, rootcontext.cs : Ensure we define and generate
3046 attribute types before anything else.
3048 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
3049 and flag the new error -20 for the case when the attribute type
3050 does not have valid targets specified. csc does not catch this.
3052 * ../errors/errors.txt : update for error # -20
3054 2002-04-11 Ravi Pratap <ravi@ximian.com>
3056 * support.cs (InternalParameters.ParameterModifier): Do some null
3057 checking and return sane values.
3059 * class.cs (Method.Define): If we are a PInvoke method, ensure
3060 that we are static and extern. Report error # 601
3062 * ../errors/cs0601.cs : Add test case for the above error.
3064 2002-04-07 Ravi Pratap <ravi@ximian.com>
3066 * rootcontext.cs (attribute_types): We need to keep type of
3067 all attribute types separately and emit code for them first.
3069 (RegisterAttribute) : Implement.
3071 * class.cs (DefineType): Check if the current Type is a custom
3072 attribute type and register it accordingly.
3074 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
3075 adding the first attribute twice and rename to
3077 (SetGlobalAttributes): this.
3079 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
3082 * attribute.cs (ApplyAttributes): Take an additional argument telling us
3083 if we are processing global arguments. Hmm, I am unsure of this.
3085 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
3087 * expression.cs: added static array of strings to avoid calling
3088 Enum.ToString () for Operator in Binary. Significant recover of
3091 2002-04-10 Miguel de Icaza <miguel@ximian.com>
3093 * class.cs (FindMembers): Allow the Builders of the various
3094 members to be null. If they are skip them. This only happens
3095 during the PInvoke declaration.
3097 2002-04-09 Miguel de Icaza <miguel@ximian.com>
3099 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
3100 failure, so we do not keep going afterwards.
3102 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
3103 wanted to pass `false' as the `is_delegate' argument. If this is
3104 the case, why not use delegate_type == null to mean `is_delegate =
3105 false' and anything else as is_delegate = true.
3107 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
3109 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
3110 code for the section, not the beginning of the tests.
3112 2002-04-08 Miguel de Icaza <miguel@ximian.com>
3114 * cfold.cs: Handle operator + (Enum x, Underlying x)
3116 * expression.cs (Binary): same. Warn about errors where we have
3117 Enum/Enum in operator + as well.
3119 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
3122 - added support for switch(bool)
3123 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
3124 - add TableSwitchEmit() to handle table-based switch statements
3126 2002-04-05 Ravi Pratap <ravi@ximian.com>
3128 * expression.cs (Invocation.OverloadResolve): Factor out code which
3129 does parameter compatibility checking with arguments so that we can
3130 re-use the code even from Delegate.VerifyApplicability
3132 (VerifyArgumentsCompat): Move above code here.
3134 * delegate.cs (VerifyApplicability): Get rid of duplicate code
3135 and instead make a call to the above method.
3137 2002-03-31 Ravi Pratap <ravi@ximian.com>
3139 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
3140 We use it to keep track of classes which are attribute types.
3142 2002-04-02 Miguel de Icaza <miguel@ximian.com>
3144 * delegate.cs (Delegate.Define): Correctly define the types in the
3145 presence of fixed and array parameters.
3147 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
3150 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
3151 include NonPublic after the first iteration.
3153 * class.cs (Indexer.CheckBase): Only check if both parents are
3156 * cs-parser.jay (accessor_body): If empty, set to null.
3158 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
3159 same code path here to resolve constants names that we did have in
3160 MemberAccess.DoResolve. There is too much code duplicated here.
3162 2002-04-01 Miguel de Icaza <miguel@ximian.com>
3164 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
3166 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
3169 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
3170 tokens, numbers and strings.
3172 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
3175 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
3176 asyncronous parameters and the regular parameters.
3178 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
3179 specify the target directory.
3181 * expression.cs: (This.DoResolve): Simplify
3182 (As.Emit): Optimize, do not generate IsInst if the expression is
3183 always of the given type.
3185 (Is.DoResolve): Bug fix, we were reporting both always/never for
3188 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
3189 creating too many unnecessary arrays.
3191 2002-03-31 Miguel de Icaza <miguel@ximian.com>
3193 * class.cs (EmitFieldInitializer): Use Assign expression to assign
3194 fields instead of rolling our own initializer. Takes care of all
3195 implicit conversions, and drops unnecessary static checks/argument.
3197 2002-03-31 Dick Porter <dick@ximian.com>
3199 * driver.cs: use the GetDirectories() return values properly, and
3200 use "/" as path separator.
3202 2002-03-30 Miguel de Icaza <miguel@ximian.com>
3204 * expression.cs (Unary): Optimize - - expr into expr.
3205 (Binary): Optimize a + (-b) into a -b.
3207 * codegen.cs (CodeGen): Made all methods static.
3209 2002-03-29 Miguel de Icaza <miguel@ximian.com>
3213 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
3214 TypeBuilder property.
3216 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
3219 * tree.cs: Removed the various RecordXXXX, and replaced with a
3220 single RecordDecl. Removed all the accessor methods, and just
3221 left a single access point Type
3223 * enum.cs: Rename DefineEnum to DefineType.
3225 * decl.cs: New abstract method `DefineType' used to unify the
3226 Defines for Enumerations, Interfaces, TypeContainers and
3229 (FindType): Moved LookupInterfaceOrClass here. Moved the
3230 LookupBaseClasses method that used to live in class.cs and
3231 interface.cs here, and renamed to FindType.
3233 * delegate.cs: Implement DefineType. Take advantage of the
3234 refactored pattern for locating the parent builder without taking
3235 the parent_builder argument (which we know does not work if we are
3236 nested, and triggering a toplevel definition).
3238 2002-03-28 Miguel de Icaza <miguel@ximian.com>
3240 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
3241 accessibility of a member has changed during override and report
3244 * class.cs (Method.Define, Property.Define): Only complain on
3245 overrides if the method is private, any other accessibility is
3246 fine (and since we just checked the permission is the same, we are
3249 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
3250 and elif are processed always. The other pre-processing
3251 directives are only processed if we are "taking" the path
3253 2002-03-29 Martin Baulig <martin@gnome.org>
3255 * class.cs (Method.Emit): Only emit symbolic debugging info if the
3256 current location is not Null.
3258 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
3259 a separate method so we can profile it.
3261 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
3262 `span.Seconds' are just seconds, but no minutes or hours.
3263 (MainDriver): Profile the CodeGen.SaveSymbols calls.
3265 2002-03-28 Miguel de Icaza <miguel@ximian.com>
3267 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
3268 Remove the gratuitous set of Final:
3270 // If an interface implementation, then we can set Final.
3271 if (((flags & MethodAttributes.Abstract) == 0) &&
3272 implementing.DeclaringType.IsInterface)
3273 flags |= MethodAttributes.Final;
3275 I do not know what I was smoking when I used that.
3278 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
3279 step into fixing the name resolution issues for delegates and
3280 unifying the toplevel name resolution.
3282 2002-03-28 Martin Baulig <martin@gnome.org>
3284 * class.cs (Method.Emit): If we have a symbol writer, call its
3285 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
3286 tell it about the current method.
3288 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
3289 writer that we're going to emit the first byte of IL code for a new
3290 statement (a new source line).
3291 (EmitContext.EmitTopBlock): If we have a symbol writer, call
3292 EmitContext.Mark() before emitting any code.
3294 * location.cs (SymbolDocument): Return null when we're Null.
3296 * statement.cs (Statement): Moved the `Location loc' variable here.
3297 (Statement.EmitBoolExpression): If we have a symbol writer, call
3298 ec.Mark() before emitting any code to tell it that we're at the
3299 beginning of a new statement.
3300 (StatementExpression): Added `Location' argument to the constructor.
3301 (Block): Added public readonly variable `StartLocation' and public
3302 variable `EndLocation'. The latter is to be set using SetEndLocation().
3303 (Block): Added constructor which takes a start and end location.
3304 (Block.SetEndLocation): New method. This sets the end location.
3305 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
3306 local variables we create.
3307 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
3308 each statement and do also mark the begin and end of the block.
3310 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
3311 tell it the current lexer.Location, use Location.Null for the end of the
3313 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
3314 current block, set its end location using SetEndLocation().
3315 (statement_expression): StatementExpression constructor now takes the
3316 lexer.Location as additional argument.
3317 (for_statement, declare_local_variables): Likewise.
3318 (declare_local_variables): When creating a new implicit block, use the
3319 new Block constructor and pass it the lexer.Location.
3321 2002-03-28 Miguel de Icaza <miguel@ximian.com>
3323 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
3324 members also on the parent interfaces recursively.
3326 2002-03-27 Miguel de Icaza <miguel@ximian.com>
3328 * report.cs: Use new formats, since Gonzalo finished the missing
3331 * expression.cs (Binary.ResolveOperator): added missing operator|
3332 operator& and operator^ for bool/bool.
3334 * cs-parser.jay: CheckDef now takes a Location argument that is
3335 used to report errors more precisly (instead of reporting the end
3336 of a definition, we try to track something which is a lot closer
3337 to the source of the problem).
3339 * cs-tokenizer.cs: Track global token use, so we can properly flag
3340 the use of #define/#undef after the first token has been seen.
3342 Also, rename the reportXXXX to Error_DescriptiveName
3344 * decl.cs (DeclSpace.IsTopLevel): Move property here from
3345 TypeContainer, so that Enum and Interface can use this too.
3347 * class.cs (TypeContainer.LookupInterfaceOrClass,
3348 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
3349 `builder' argument. Typically this was used to pass the parent
3350 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
3353 The problem is that a nested class could trigger the definition of
3354 a toplevel class, and the builder would be obviously wrong in that
3357 So we drop this argument, and we compute dynamically the
3358 TypeBuilder/ModuleBuilder (the correct information was available
3359 to us anyways from DeclSpace.Parent)
3361 * interface.cs (Interface.DefineInterface): Drop builder
3362 parameter cleanup like class.cs
3364 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
3367 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
3370 (Try.Emit): Propagate the returns value from the statement.
3372 (Return.Emit): Even if we are leavning
3374 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
3376 * modifiers.cs: Fix the computation of MethodAttributes flags.
3378 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
3380 * driver.cs: allow compilation of files that start with '/'.
3381 Add a default case when checking the argument of --target.
3383 2002-03-25 Miguel de Icaza <miguel@ximian.com>
3385 * interface.cs: Implement the same search algorithm for types in
3388 * delegate.cs: Do not allow multiple definition.
3390 * Recovered ChangeLog that got accidentally amputated
3392 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
3394 * rootcontext.cs: Load manually enum to allow core classes to
3395 contain enumerations.
3397 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
3398 Update to new static methods in TypeManager.
3400 * typemanager.cs (GetMethod, GetConstructor): Use our
3401 implementation of FindMembers to find the members, since during
3402 corlib compilation, the types are TypeBuilders and GetMethod and
3403 GetConstructor do not work.
3405 Make all methods in TypeManager static.
3407 (InitCodeHelpers): Split the functionality from
3408 the InitCodeTypes function.
3410 * driver.cs: Call InitCodeHelpers after we have populated the
3413 * cs-parser.jay (delegate_declaration): we did not used to compute
3414 the delegate name correctly for void delegates.
3416 2002-03-24 Miguel de Icaza <miguel@ximian.com>
3418 * rootcontext.cs (RootContext): Init the interface_resolve_order
3419 and type_container_resolve_order always.
3421 (ResolveCore, BootstrapCorlib_ResolveClass,
3422 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
3423 compiler when compiling with --nostdlib
3425 * class.cs (TypeContainer.DefineType): Check that our parent is
3426 not null. This test is most important when we are bootstraping
3429 * codegen.cs: Split out the symbol writing code.
3431 2002-03-25 Martin Baulig <martin@gnome.org>
3433 * driver.cs (-g): Made -g an alias for --debug.
3435 2002-03-24 Martin Baulig <martin@gnome.org>
3437 * codegen.cs (SymbolWriter): New public variable. Returns the
3438 current symbol writer.
3439 (CodeGen): Added `bool want_debugging_support' argument to the
3440 constructor. If true, tell the ModuleBuild that we want debugging
3441 support and ask it for the ISymbolWriter.
3442 (Save): If we have a symbol writer, call it's Close() method after
3443 saving the assembly.
3445 * driver.c (--debug): New command line argument to create a
3446 debugger information file.
3448 * location.cs (SymbolDocument): New public property. Returns an
3449 ISymbolDocumentWriter object for the current source file or null
3450 if we don't have a symbol writer.
3452 2002-03-21 Miguel de Icaza <miguel@ximian.com>
3454 * driver.cs (LoadAssembly): Correctly return when all the paths
3455 have been tried and not before.
3457 * statement.cs (Switch.Emit): return the actual coverage for this
3458 statement (returns/not-returns)
3460 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
3461 switch of the statement if we are the last switch section. That
3462 kills two problems: try/catch problems (we used to emit an empty
3463 nop at the end) and switch statements where all branches would
3466 2002-03-19 Miguel de Icaza <miguel@ximian.com>
3468 * driver.cs: Add default assemblies (the equivalent to the
3469 Microsoft CSC.RSP file)
3471 * cs-tokenizer.cs: When updating `cols and setting it to zero,
3472 also update tokens_seen and set it to false.
3474 * driver.cs: Implement --recurse for Mike.
3476 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
3477 correctly splitting out the paths.
3479 2002-03-18 Miguel de Icaza <miguel@ximian.com>
3481 * interface.cs (Interface.PopulateProperty): Instead of using
3482 `parent' as the declaration space for the set parameters, use
3485 * support.cs (InternalParameters): InternalParameters constructor
3486 takes a DeclSpace instead of a TypeContainer.
3488 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
3489 types are being initialized, load the address of it before calling
3492 (New): Provide a mechanism to disable the generation of local
3493 value type temporaries when the caller will be providing us with
3494 an address to store it.
3496 (ArrayCreation.EmitDynamicInitializers): Use it.
3498 2002-03-17 Miguel de Icaza <miguel@ximian.com>
3500 * expression.cs (Invocation.EmitArguments): Only probe for array
3501 property if there is more than one argument. Sorry about that.
3503 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
3506 * class.cs (Method.LabelParameters): Fix incorrect code path that
3507 prevented the `ParamArrayAttribute' from being applied to the
3510 2002-03-16 Miguel de Icaza <miguel@ximian.com>
3512 * support.cs (ReflectionParameters): Correctly compute whether the
3513 last argument is a params array. Fixes the problem with
3516 * typemanager.cs: Make the assemblies array always be non-null
3517 (empty, but non-null)
3519 * tree.cs (RecordDecl): New function that abstracts the recording
3520 of names. This reports error 101, and provides a pointer to the
3521 previous declaration. Fixes a crash in the compiler.
3523 * cs-parser.jay (constructor_declaration): Update to new grammar,
3524 and provide a constructor_body that can be empty.
3526 2002-03-15 Miguel de Icaza <miguel@ximian.com>
3528 * driver.cs: Add support for --resources.
3530 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
3531 Make all types for the various array helper methods be integer.
3533 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
3534 CheckState to ConvCast.
3536 (ConvCast): Now it takes a `checked' state argument, to avoid
3537 depending on the emit context for the conversion, and just using
3538 the resolve time setting.
3540 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
3541 instead of Invocation.EmitArguments. We do not emit the original
3542 arguments, instead we emit those which have been converted to
3543 unsigned int expressions.
3545 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
3547 * codegen.cs: ditto.
3549 * expression.cs (LocalVariableReference): Drop the use of the
3550 Store function that depended on the variable index.
3552 * statement.cs (VariableInfo): Drop the `Idx' property from this
3553 class, as this is not taking into account the indexes for
3554 temporaries tat we generate during the execution, getting the
3557 * class.cs: First emit class initializers, then call the parent
3560 * expression.cs (Binary): Fix opcode emision.
3561 (UnaryMutator.EmitCode): Support checked code generation
3563 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
3564 matches for events for both the Static and Instance scans,
3565 pointing to the same element. Fix that.
3567 2002-03-14 Miguel de Icaza <miguel@ximian.com>
3569 * rootcontext.cs (ResolveTree): Always set the
3570 interface_resolve_order, because nested interfaces will be calling
3573 * class.cs (GetInterfaceOrClass): Track the same resolution
3574 process used by TypeManager.LookupType. This fixes the nested
3575 type lookups in class declarations (separate path from
3578 (TypeContainer.DefineType): Also define nested interfaces.
3579 (TypeContainer.RegisterOrder): New public function used to
3580 register the order in which child interfaces need to be closed.
3582 Nested interfaces need to be closed after their parents have been
3585 * interface.cs (InterfaceAttr): Put all the logic for computing
3586 the interface attribute here.
3588 (DefineInterface): Register our interface order with the
3589 RootContext or with the TypeContainer depending on the case.
3591 2002-03-12 Miguel de Icaza <miguel@ximian.com>
3593 * cs-parser.jay: rework foreach statement to work with the new
3594 changes to the policy on SimpleNames.
3596 * report.cs: support Stacktrace on warnings as well.
3598 * makefile: drop --unsafe and /unsafe from the compile.
3600 2002-03-13 Ravi Pratap <ravi@ximian.com>
3602 * ecore.cs (StandardConversionExists): Modify to take an Expression
3603 as the first parameter. Ensure we do null -> reference type conversion
3606 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
3607 temporary Expression objects.
3609 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
3611 * interface.cs: workaround bug in method overloading resolution
3612 (there is already a bugzilla bug for it).
3614 2002-03-12 Miguel de Icaza <miguel@ximian.com>
3616 We could also solve this problem by having a separate path for
3617 performing type lookups, instead of DoResolve, we could have a
3618 ResolveType entry point, and only participating pieces of the
3619 production (simplename, deref, array) would implement this.
3621 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
3622 signal SimpleName to only resolve type names and not attempt to
3623 resolve anything else.
3625 * expression.cs (Cast): Set the flag.
3627 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
3629 * class.cs: Only report 108 if there is no `new' modifier.
3631 * cs-parser.jay: rework foreach statement to work with the new
3632 changes to the policy on SimpleNames.
3634 * report.cs: support Stacktrace on warnings as well.
3636 * makefile: drop --unsafe and /unsafe from the compile.
3638 2002-03-11 Miguel de Icaza <miguel@ximian.com>
3640 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
3641 lookups here, instead of doing that at parse time. This means
3642 that our grammar will not introduce `LocalVariableReferences' as
3643 expressions at this point. That solves the problem of code like
3651 This is only half the fix. The full fix requires parameters to
3652 also be handled in this way.
3654 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
3655 makes the use more obvious of the DeclSpace. The
3656 ec.TypeContainer.TypeBuilder is now only used to pull the
3659 My theory is that I can get rid of the TypeBuilder completely from
3660 the EmitContext, and have typecasts where it is used (from
3661 DeclSpace to where it matters).
3663 The only pending problem is that the code that implements Aliases
3664 is on TypeContainer, and probably should go in DeclSpace.
3666 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
3667 lookups here, instead of doing that at parse time. This means
3668 that our grammar will not introduce `LocalVariableReferences' as
3669 expressions at this point. That solves the problem of code like
3677 This is only half the fix. The full fix requires parameters to
3678 also be handled in this way.
3680 * class.cs (Property.DefineMethod): When implementing an interface
3681 method, set newslot, when implementing an abstract method, do not
3682 set the flag (before we tried never setting it, or always setting
3683 it, which is the difference).
3684 (Indexer.DefineMethod): same.
3685 (Method.DefineMethod): same.
3687 * ecore.cs: Only set the status used flag if we get back a Field.
3689 * attribute.cs: Temporary hack, so Paolo can keep working.
3691 2002-03-08 Ravi Pratap <ravi@ximian.com>
3693 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
3694 the unmanaged type in the case we have a MarshalAs attribute.
3696 (Resolve): Handle the case when we are parsing the special MarshalAs
3697 attribute [we need to store the unmanaged type to use later]
3699 * typemanager.cs (marshal_as_attr_type): Built in type for the
3700 MarshalAs Attribute.
3702 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
3703 on parameters and accordingly set the marshalling info.
3705 2002-03-09 Miguel de Icaza <miguel@ximian.com>
3707 * class.cs: Optimizing slightly by removing redundant code after
3708 we switched to the `NoTypes' return value.
3709 (Property.DefineMethod): use NoTypes here too.
3711 This fixes the bug I introduced in my last batch of changes.
3713 2002-03-05 Ravi Pratap <ravi@ximian.com>
3715 * tree.cs (RecordEnum): Add. We now keep track of enums too.
3717 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
3718 Enums since those are types too.
3720 * cs-parser.jay (enum_declaration): Record enums as we parse them.
3722 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
3723 thanks to a call during the lookup process.
3725 2002-03-07 Miguel de Icaza <miguel@ximian.com>
3727 * statement.cs (Foreach): Lots of work to accomodate a particular
3728 kind of foreach statement that I had not kept in mind. It is
3729 possible to have foreachs on classes that provide a GetEnumerator
3730 method that return objects that implement the "pattern" for using
3731 a foreach, there is no need to support GetEnumerator
3734 This is needed to compile nant.
3736 * decl.cs: Only report 114 if the member is not `Finalize' and if
3737 the warning level is at least 2.
3739 * class.cs: Moved the compare function from Method to
3742 (MethodSignature.InheritableMemberSignatureCompare): Add new
3743 filter function that is used to extract inheritable methods from a
3746 (Method.Define): Use the new `inheritable_method_signature_filter'
3749 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
3752 2002-03-06 Miguel de Icaza <miguel@ximian.com>
3754 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
3756 * cs-parser.jay: Add opt_semicolon to the interface declaration.
3758 * expression.cs: Pass location information to
3759 ConvertImplicitStandard.
3761 * class.cs: Added debugging code to track return values from
3764 2002-03-05 Miguel de Icaza <miguel@ximian.com>
3766 * expression.cs (Is.DoResolve): If either side of the `is' is an
3767 interface, do not flag the warning.
3769 * ecore.cs (ImplicitReferenceConversion): We need a separate test
3772 * report.cs: Allow for --fatal to be used with --probe.
3774 * typemanager.cs (NoTypes): Move the definition for the empty Type
3777 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
3779 (TypeContainer.DefineProxy): New function used to proxy to parent
3780 implementations when implementing interfaces.
3781 (TypeContainer.ParentImplements): used to lookup if our parent
3782 implements a public function that is required by an interface.
3783 (TypeContainer.VerifyPendingMethods): Hook this up.
3785 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
3786 `modules' and `assemblies' arraylists into arrays. We only grow
3787 these are the very early start up of the program, so this improves
3788 the speedof LookupType (nicely measured).
3790 * expression.cs (MakeByteBlob): Replaced unsafe code with
3791 BitConverter, as suggested by Paolo.
3793 * cfold.cs (ConstantFold.Binary): Special case: perform constant
3794 folding of string concatenation, but if either side is a string,
3795 and the other is not, then return null, and let the runtime use
3796 the concatenation on the string plus the object (using
3799 2002-03-04 Miguel de Icaza <miguel@ximian.com>
3801 Constant Folding has been implemented now.
3803 * expression.cs (Unary.Reduce): Do not throw an exception, catch
3804 the error instead on types that are not supported in one's
3807 * constant.cs (Constant and all children): New set of functions to
3808 perform implict and explicit conversions.
3810 * ecore.cs (EnumConstant): Implement the new functions to perform
3811 conversion by proxying to the child expression.
3813 * codegen.cs: (ConstantCheckState): Constant evaluation has its
3814 own separate setting that can not be turned off from the command
3815 line using --unchecked or --checked and is only controlled using
3816 the checked/unchecked statements and expressions. This setting is
3817 used by the constant folder to flag errors.
3819 * expression.cs (CheckedExpr, UncheckedExpr): Set the
3820 ConstantCheckState as well.
3822 During Resolve, they also have to flag the state, because the
3823 constant folder runs completely in the Resolve phase.
3825 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
3828 2002-03-01 Miguel de Icaza <miguel@ximian.com>
3830 * cfold.cs: New file, this file contains the constant folder.
3832 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
3833 argument to track whether we are using the resulting address to
3834 load or store a value and provide better error messages.
3836 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
3837 new AddressOf arguments.
3839 * statement.cs (Foreach.EmitCollectionForeach): Update
3841 * expression.cs (Argument.Emit): Call AddressOf with proper
3842 arguments to track usage.
3844 (New.DoEmit): Call AddressOf with new arguments.
3846 (Unary.Emit): Adjust AddressOf call.
3848 2002-03-01 Ravi Pratap <ravi@ximian.com>
3850 * cs-parser.jay (member_access): Change the case for pre-defined types
3851 to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
3854 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
3857 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
3858 essentially like methods and apply attributes like MethodImplOptions to them too.
3860 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
3863 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
3864 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
3867 * Update code everywhere accordingly.
3869 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
3871 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
3873 2002-02-28 Ravi Pratap <ravi@ximian.com>
3875 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
3876 try performing lookups against those instead of jumping straight into using
3877 the 'using' clauses.
3879 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
3881 (LookupType): Perform lookups in implicit parents too.
3883 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
3884 sequence as RootContext.LookupType.
3886 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
3887 the various cases of namespace lookups into this method.
3889 2002-03-01 Miguel de Icaza <miguel@ximian.com>
3891 * cs-parser.jay: Add support for [Attribute ()] (empty arguments
3892 in positional arguments)
3894 * class.cs (Operator): Update the AllowedModifiers to contain
3897 * cs-parser.jay: Update operator declaration to allow for the
3898 operator body to be empty.
3900 * cs-tokenizer.cs: Added '\u' unicode support in strings and hex
3903 2002-02-27 Miguel de Icaza <miguel@ximian.com>
3905 * class.cs (Method.Emit): Label parameters.
3907 * driver.cs: Return 1 or 0 as the program exit code.
3909 2002-02-26 Miguel de Icaza <miguel@ximian.com>
3911 * expression.cs: Special case the `null' object when trying to
3912 auto-compute the type, as anything can be explicitly converted to
3915 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
3916 spotting this Paolo.
3918 (Expression.ImplicitNumericConversion): Perform comparissions of
3919 the type using the underlying type in the case of an enumeration
3920 rather than using the enumeration type for the compare.
3922 Cope with the underlying == type case, which is not possible to
3925 (Expression.ConvertNumericExplicit): Perform comparissions of
3926 the type using the underlying type in the case of an enumeration
3927 rather than using the enumeration type for the compare.
3929 * driver.cs: If the user does not supply an extension, assume .exe
3931 * cs-parser.jay (if_statement): Rewrote so that we can track the
3932 location for the if statement.
3934 * expression.cs (Binary.ConstantFold): Only concat strings when
3935 the operation is "+", not everything ;-)
3937 * statement.cs (Statement.EmitBoolExpression): Take a location
3939 (If, While, Do): Track location.
3941 * expression.cs (Binary.ResolveOperator): In the object + string
3942 case, I was missing a call to ConvertImplicit
3944 2002-02-25 Ravi Pratap <ravi@ximian.com>
3946 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
3947 Location arguments. Ensure we use RootContext.LookupType to do our work
3948 and not try to do a direct Type.GetType and ModuleBuilder.GetType
3950 * interface.cs (PopulateMethod): Handle the type of the parameter being
3953 * expression.cs (Invocation.BetterFunction): Handle the case when we
3954 have a params method with no fixed arguments and a call is made with no
3957 2002-02-25 Miguel de Icaza <miguel@ximian.com>
3959 * cs-tokenizer.cs: Add support for the quote-escape-sequence in
3960 the verbatim-string-literal
3962 * support.cs (InternalParameters.ParameterModifier): handle null
3964 (InternalParameters.ParameterType): ditto.
3966 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
3967 duplicating the name of the variable parameter.
3968 (GetParameterByName): Fix bug where we were not looking up array
3969 paramters if they were the only present (thanks Paolo!).
3970 (GetParameterInfo): We only have an empty set of types if both
3971 fixed and array are set to null.
3972 (GetParameterInfo-idx): Handle FixedParameter == null
3974 * cs-parser.jay: Handle the case where there is no catch
3975 statements (missing null test).
3977 2002-02-22 Miguel de Icaza <miguel@ximian.com>
3979 * driver.cs (MainDriver): Be conservative on our command line
3982 Catch DirectoryNotFoundException when calling GetFiles.
3984 (SplitPathAndPattern): Used to split the input specification into
3985 a path and a pattern that we can feed to Directory.GetFiles.
3987 2002-02-21 Miguel de Icaza <miguel@ximian.com>
3989 * statement.cs (Fixed): Implement the last case of the Fixed
3990 statement (string handling).
3992 * expression.cs (StringPtr): New class used to return a char * to
3993 a string; Used by the Fixed statement.
3995 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
3997 * expression.cs (Binary.ResolveOperator): Remove redundant
3998 MemberLookup pn parent type.
3999 Optimize union call, we do not need a union if the types are the same.
4000 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
4003 Specialize the use of MemberLookup everywhere, instead of using
4004 the default settings.
4006 (StackAlloc): Implement stackalloc keyword.
4008 * cs-parser.jay: Add rule to parse stackalloc.
4010 * driver.cs: Handle /h, /help, /?
4012 * expression.cs (MakeByteBlob): Removed the hacks we had in place
4013 before we supported unsafe code.
4015 * makefile: add --unsafe to the self compilation of mcs.
4017 2002-02-20 Miguel de Icaza <miguel@ximian.com>
4019 * expression.cs (PointerArithmetic): New class that is used to
4020 perform pointer arithmetic.
4021 (Binary.Resolve): Handle pointer arithmetic
4022 Handle pointer comparission.
4023 (ArrayPtr): Utility expression class that is used to take the
4024 address of an array.
4026 (ElementAccess): Implement array access for pointers
4028 * statement.cs (Fixed): Implement fixed statement for arrays, we
4029 are missing one more case before we are done.
4031 * expression.cs (Indirection): Implement EmitAssign and set the
4032 ExprClass to Variable. This allows pointer dereferences to be
4033 treated as variables, and to have values assigned to them.
4035 * ecore.cs (Expression.StoreFromPtr): New utility function to
4036 store values dereferencing.
4038 2002-02-20 Ravi Pratap <ravi@ximian.com>
4040 * expression.cs (Binary.ResolveOperator): Ensure that we are
4041 not trying to operate on a void type - this fixes the reported
4044 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
4045 the parent implementation is sealed.
4047 * ../errors/cs0239.cs : Add.
4049 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
4051 * typemanager.cs (unverifiable_code_type): Corresponds to
4052 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
4053 which have unsafe code in them.
4055 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
4058 2002-02-19 Miguel de Icaza <miguel@ximian.com>
4060 * cs-tokenizer.cs: Add support for @"litreal strings"
4062 Make tokenizer accept pre-processor directives
4063 on any column (remove the old C-like limitation).
4065 * rootcontext.cs (EmitCode): Emit any global attributes.
4066 (AddGlobalAttributes): Used to keep track of assembly attributes.
4068 * attribute.cs (ApplyAttributes): Support AssemblyAttributes.
4070 * cs-parser.jay: Add support for global attributes.
4072 2002-02-17 Miguel de Icaza <miguel@ximian.com>
4074 * expression.cs (Indirection): New helper class. Unary will
4075 create Indirection classes to be able to implement the
4076 IMemoryLocation interface on it.
4078 2002-02-16 Miguel de Icaza <miguel@ximian.com>
4080 * cs-parser.jay (fixed_statement): reference the right statement.
4082 * statement.cs (Fixed.Emit): Finish implementing the fixed
4083 statement for the &x case.
4085 2002-02-14 Miguel de Icaza <miguel@ximian.com>
4087 * class.cs (Property.Define, Method.Define): Remove newslot when
4090 * modifiers.cs: My use of NewSlot when `Abstract' was set was
4091 wrong. NewSlot should only be used if the `new' keyword is present.
4093 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
4094 locating our system dir. Sorry about this.
4096 2002-02-13 Miguel de Icaza <miguel@ximian.com>
4098 * driver.cs (GetSystemDir): Compute correctly the location of our
4099 system assemblies. I was using the compiler directory instead of
4100 the library directory.
4102 2002-02-13 Ravi Pratap <ravi@ximian.com>
4104 * expression.cs (BetterFunction): Put back in what Miguel commented out
4105 since it is the correct fix. The problem is elsewhere ;-)
4107 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
4108 parameters of the parms method are themselves compatible or not !
4110 (StandardConversionExists): Fix very dangerous bug where we were forgetting
4111 to check that a class implements an interface before saying that an implicit
4112 conversion was allowed. Use ImplementsInterface to do the checking.
4114 2002-02-13 Miguel de Icaza <miguel@ximian.com>
4116 * class.cs (Method.Define): Track whether we are an explicit
4117 implementation or not. And only call DefineMethodOverride if we
4118 are an explicit implementation.
4120 (Property.DefineMethod): Ditto.
4122 2002-02-11 Ravi Pratap <ravi@ximian.com>
4124 * expression.cs (BetterFunction): Catch hideous bug which was
4125 preventing us from detecting ambiguous calls due to implicit casts i.e
4128 2002-01-29 Miguel de Icaza <miguel@ximian.com>
4130 * support.cs (Pair): Remove un-needed method. I figured why I was
4131 getting the error in cs-parser.jay, the variable in a foreach loop
4132 is readonly, and the compiler does not really treat this as a variable.
4134 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
4135 instead of EQUALS in grammar.
4137 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
4139 * expression.cs (Unary.DoResolve): Check whether the argument is
4142 2002-01-28 Miguel de Icaza <miguel@ximian.com>
4144 * support.cs: Api for Pair to set a value. Despite the fact that
4145 the variables are public the MS C# compiler refuses to compile
4146 code that accesses the field if the variable is part of a foreach
4149 * statement.cs (Fixed): Begin implementation of the fixed
4152 (Block.AddVariable): Return the VariableInfo on success and null
4153 on failure instead of true/false.
4155 * cs-parser.jay (foreach): Catch errors on variables already
4156 defined (we were ignoring this value before) and properly unwind
4159 (fixed_statement): grammar for the fixed statement.
4161 2002-01-25 Miguel de Icaza <miguel@ximian.com>
4163 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
4164 pointer types to be incretemented.
4166 (SizeOf): Implement.
4168 * cs-parser.jay (pointer_member_access): Implement
4169 expr->IDENTIFIER production.
4171 * expression.cs (IndexerAccess.DoResolve, ArrayAccess.DoResolve,
4172 MemberAccess.DoResolve, Invocation.DoResolve): Check for pointers
4175 (Unary): Implement indirection.
4177 * ecore.cs (Expression.UnsafeError): Reports error 214 (pointer
4178 use in non-unsafe context).
4180 (SimpleName.DoResolve): Check for pointers in field access on safe
4183 (Expression.LoadFromPtr): Factor the load-indirect code in this
4184 function. This was duplicated in UnboxCast and ParameterReference
4186 2002-01-24 Miguel de Icaza <miguel@ximian.com>
4188 * expression.cs (ComposedCast): report an error if a pointer cast
4189 is used in a safe region.
4191 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
4192 pointer type casts in unsafe context.
4194 * codegen.cs (EmitContext): Set up IsUnsafe.
4196 * cs-parser.jay (non_expression_type): Add productions for pointer
4199 * expression.cs (Invocation.EmitCall): Remove chunk of buggy
4200 code. We should not use force into static mode if the method is
4201 not virtual. Fixes bug in MIS
4203 * statement.cs (Do.Emit, While.Emit, For.Emit,
4204 Statement.EmitBoolExpression): Add support to Do and While to
4205 propagate infinite loop as `I do return' semantics.
4207 Improve the For case to also test for boolean constants.
4209 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
4210 to the list of attributes we can add.
4212 Remove `EmitContext' argument.
4214 * class.cs (Method.Define): Apply parameter attributes.
4215 (Constructor.Define): Apply parameter attributes.
4216 (MethodCore.LabelParameters): Move here the core of labeling
4219 * support.cs (ReflectionParameters.ParameterModifier,
4220 InternalParameters.ParameterModifier): Use IsByRef on the type and
4221 only return the OUT bit for these parameters instead of in/out/ref
4224 This is because I miss-understood things. The ParameterInfo.IsIn
4225 and IsOut represent whether the parameter has the [In] and [Out]
4228 2002-01-22 Miguel de Icaza <miguel@ximian.com>
4230 * ecore.cs (FieldExpr.Emit): Release temporaries.
4232 * assign.cs (LocalTemporary.Release): new function.
4234 * codegen.cs (EmitContext.GetTemporaryStorage,
4235 EmitContext.FreeTemporaryStorage): Rework the way we deal with
4236 temporary storage. Now we can "put back" localbuilders when we
4239 2002-01-21 Miguel de Icaza <miguel@ximian.com>
4241 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
4242 need to make a copy of the variable to generate verifiable code.
4244 2002-01-19 Miguel de Icaza <miguel@ximian.com>
4246 * driver.cs: Compute dynamically the system directory.
4248 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
4249 Slower, but more generally useful. Used by the abstract
4250 registering implementation.
4252 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
4253 the rules for the special rule on Type/instances. First check if
4254 we have the same name, and if so, try that special static path
4255 rather than the instance path.
4257 2002-01-18 Miguel de Icaza <miguel@ximian.com>
4259 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
4262 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
4263 Enum, ValueType, Delegate or Array for non-corlib compiles.
4265 * cs-tokenizer.cs: Catch long identifiers (645)
4267 * typemanager.cs (IndexerPropetyName): Ravi never tested this
4270 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
4271 fix, we were returning too early, so we were not registering
4272 pending methods from abstract classes.
4274 Do not register pending methods if the class is abstract.
4276 * expression.cs (Conditional.DoResolve): Report circular implicit
4277 conversions when we neecd to compute it for conditional
4280 (Is.DoResolve): If the expression is always of the provided type,
4281 flag warning 183. If the expression can not ever be of the
4282 provided type flag warning 184.
4284 * class.cs: Catch 169 as well.
4286 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
4289 2002-01-18 Nick Drochak <ndrochak@gol.com>
4291 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.
4293 2002-01-17 Miguel de Icaza <miguel@ximian.com>
4295 * interface.cs: (PopulateMethod): Check for pointers being defined
4296 only if the unsafe context is active.
4297 (PopulateProperty): ditto.
4298 (PopulateIndexer): ditto.
4300 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
4301 specified. If pointers are present, make sure that they are
4302 present in an unsafe context.
4303 (Constructor, Constructor.Define): ditto.
4304 (Field, Field.Define): ditto.
4305 (Property, Property.Define): ditto.
4306 (Event, Event.Define): ditto.
4308 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
4309 hashtable if there are classes or structs defined.
4311 * expression.cs (LocalVariableReference.DoResolve): Simplify this
4312 code, as the constant resolution moved.
4314 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
4315 the metadata, so we can flag error 133.
4317 * decl.cs (MemberCore.UnsafeOK): New function to test that a
4318 pointer is being declared in an unsafe context.
4320 2002-01-16 Miguel de Icaza <miguel@ximian.com>
4322 * modifiers.cs (Modifiers.Check): Require a Location argument.
4323 Report error 227 for Unsafe use.
4325 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
4327 * statement.cs (For.Emit): If the test is null, then report that
4328 we do `return', as we wont reach anything afterwards.
4330 (Switch.SwitchGoverningType): Track the expression that matched
4333 * driver.cs: Allow negative numbers as an error code to flag.
4335 * cs-parser.jay: Handle 1551.
4337 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
4339 2002-01-15 Miguel de Icaza <miguel@ximian.com>
4341 * cs-parser.jay: Report 1518 (type declaration can only contain
4342 class, struct, interface, enum or delegate)
4344 (switch_label): Report 1523 (keywords `case' or `default' must
4347 (opt_switch_sections): Report 1522 (empty switch)
4349 * driver.cs: Report 1515 (response file specified multiple times)
4350 Report 1516 (Source file specified multiple times).
4352 * expression.cs (Argument.Resolve): Signal 1510
4354 (BaseAccess.Resolve, BaseIndexer.Resolve): Signal 1511 (base
4355 access not allowed in static code)
4357 2002-01-11 Ravi Pratap <ravi@ximian.com>
4359 * typemanager.cs (IsPointerType): Utility method which we are going
4362 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
4363 the object type, so we take care of that.
4365 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
4367 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
4368 added to non-params parameters :-)
4370 * typemanager.cs (CSharpName): Include 'void' type too.
4372 (void_ptr_type): Include in the set of core types.
4374 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
4377 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
4380 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
4381 completely forgotten about it.
4383 2002-01-10 Ravi Pratap <ravi@ximian.com>
4385 * cs-parser.jay (pointer_type): Add. This begins our implementation
4386 of parsing rules for unsafe code.
4388 (unsafe_statement): Implement.
4390 (embedded_statement): Modify to include the above.
4392 * statement.cs (Unsafe): Implement new class for unsafe blocks.
4394 * codegen.cs (EmitContext.InUnsafe): Add. This determines
4395 if the current context is an unsafe one.
4397 * cs-parser.jay (local_variable_pointer_type): Since local variable types
4398 are handled differently, we need separate rules for them.
4400 (local_variable_declaration): Update to use local_variable_pointer_type
4401 to allow variable declarations of unmanaged pointer types.
4403 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
4406 * ../errors/cs0214.cs : Add.
4408 2002-01-16 Nick Drochak <ndrochak@gol.com>
4410 * makefile: remove 'response' file when cleaning.
4412 2002-01-15 Miguel de Icaza <miguel@ximian.com>
4414 * cs-parser.jay: Report 1524.
4416 2002-01-14 Miguel de Icaza <miguel@ximian.com>
4418 * typemanager.cs (RegisterMethod): drop checking if we have
4419 registered this from here
4421 2002-01-12 Miguel de Icaza <miguel@ximian.com>
4423 * class.cs (Method.EmitDestructor): Implement calling our base
4426 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
4429 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
4430 this routine and will wrap the call in a try/catch block. Deal
4433 2002-01-11 Miguel de Icaza <miguel@ximian.com>
4435 * ecore.cs (Expression.MemberLookup): instead of taking a
4436 parameter `same_type' that was used to tell whether we could
4437 access private members we compute our containing type from the
4440 (FieldExpr): Added partial support for volatile fields. This does
4441 not work for volatile fields exposed from assemblies, as I can not
4442 figure out how to extract the modreq from it.
4444 Updated all the source files to use this.
4446 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
4447 because it is referenced by MemberLookup very often.
4449 2002-01-09 Ravi Pratap <ravi@ximian.com>
4451 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
4452 TypeBuilder.GetCustomAttributes to retrieve what we need.
4454 Get rid of redundant default_member_attr_type as this is the same as
4455 default_member_type which already exists.
4457 * interface.cs, attribute.cs : Update accordingly.
4459 2002-01-08 Miguel de Icaza <miguel@ximian.com>
4461 * typemanager.cs: Enable IndexerPropertyName again. It does not
4462 work for TYpeBuilders though. Ravi, can you please fix this?
4464 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
4466 * expression.cs (Argument.Emit): Handle the case of ref objects
4467 being passed to ref functions;
4469 (ParameterReference.EmitLoad): Loads the content of the pointer
4470 without dereferencing.
4472 2002-01-07 Miguel de Icaza <miguel@ximian.com>
4474 * cs-tokenizer.cs: Implemented the pre-processing expressions.
4476 2002-01-08 Ravi Pratap <ravi@ximian.com>
4478 * class.cs (Indexer.DefineMethod): Incorporate the interface
4479 type in the name of the method if we are doing explicit interface
4482 * expression.cs (ConversionExists): Remove as it is completely obsolete.
4484 (BetterConversion): Fix extremely trivial bug where we were referring to
4485 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
4488 * ../errors/bug16.cs : Add although we have fixed it.
4490 2002-01-07 Miguel de Icaza <miguel@ximian.com>
4492 * expression.cs (BaseIndexer): Begin implementation.
4494 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
4496 * cs-parser.jay (indexer_declarator): Use qualified_identifier
4497 production directly to remove a shift/reduce, and implement
4498 explicit interface implementation.
4500 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
4501 after a floating point suffix.
4503 * expression.cs (DoNumericPromotions): Improved the conversion for
4504 uint/uint. If we have a constant, we avoid doing a typecast to a
4507 * class.cs (Indexer): Implement explicit interface implementation
4510 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
4512 * class.cs: make the default instance constructor public and hidebysig.
4514 2001-01-03 Ravi Pratap <ravi@ximian.com>
4516 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
4517 so we can call it from elsewhere.
4519 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
4520 we emit it internally if the class has a defined indexer; otherwise the user
4521 emits it by decorating the class definition with the DefaultMemberAttribute.
4523 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
4524 attribute is not used on a type which defines an indexer.
4526 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
4527 character when we skip whitespace.
4529 * ../errors/cs0646.cs : Add.
4531 2002-01-03 Miguel de Icaza <miguel@ximian.com>
4533 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
4536 * makefile: Add practical target `mcs3.exe' which builds the third
4537 generation compiler.
4539 * expression.cs (New): Fix structures constructor calling.
4541 * class.cs (Property, Method, Indexer): Emit Final flag on the
4542 method if we are an interface implementation and we are not
4545 * ecore.cs (PropertyExpr): New public field `IsBase', tells
4546 whether this property is referencing a `base' method.
4548 * expression.cs (Invocation.EmitCall): take an extra argument:
4549 is_base, this is used to determine whether the `call' or
4550 `callvirt' opcode should be used.
4553 * delegate.cs: update EmitCall.
4555 * class.cs (Method.Define): Set NewSlot for the cases where we are
4556 not implementing an interface method.
4558 (Property.Define): ditto.
4560 2002-01-02 Miguel de Icaza <miguel@ximian.com>
4562 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
4563 'r'. Allows mcs to parse itself fully.
4565 2002-01-02 Ravi Pratap <ravi@ximian.com>
4567 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
4568 of the number of initializers that require the InitializeArray method.
4570 (CheckIndices): Store the Expression in all cases - not the plain value. Also
4571 update the above field where necessary.
4573 (MakeByteBlob): Update accordingly.
4575 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
4578 (EmitDynamicInitializers): Update in accordance with the new optimization.
4580 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
4581 same OpCode applies.
4583 * cs-parser.jay : Fix some glaring errors I introduced.
4585 2002-01-01 Ravi Pratap <ravi@ximian.com>
4587 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
4588 so that we can check for name clashes there too.
4590 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
4591 for interface indexers.
4593 * interfaces.cs (Define): Emit the default member attribute.
4595 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
4596 variable was being referred to while setting the value ;-)
4598 2002-01-01 Miguel de Icaza <miguel@ximian.com>
4600 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
4601 byte-by-byte information when we know the data is zero.
4603 Make the block always a multiple of 4, because
4604 DefineInitializedData has a bug.
4606 * assign.cs: Fix, we should assign from the temporary, not from
4609 * expression.cs (MakeByteBlob): Fix my incorrect code.
4611 2001-12-31 Miguel de Icaza <miguel@ximian.com>
4613 * typemanager.cs (EnumToUnderlying): This function is used to get
4614 the underlying type from an enumeration, because it does not
4617 * constant.cs: Use the I4_S form for values between -128 and 127.
4619 * statement.cs (Block.LookupLabel): Looks up a label.
4620 (Block): Drop support for labeled blocks.
4622 (LabeledStatement): New kind of statement that represents a label
4625 (Goto): Finally implement this bad boy.
4627 * cs-parser.jay: Update to reflect new mechanism to implement
4630 2001-12-30 Miguel de Icaza <miguel@ximian.com>
4632 * codegen.cs (EmitContext.This): a codegen property that keeps the
4633 a single instance of this instead of creating many different this
4636 * delegate.cs (Delegate.DoResolve): Update to use the property;
4638 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
4640 * expression.cs (BaseAccess.DoResolve): Ditto.
4642 2001-12-29 Ravi Pratap <ravi@ximian.com>
4644 * typemanager.cs (methodimpl_attr_type): Add to hold the type
4645 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
4647 (InitCoreTypes): Update accordingly.
4649 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
4650 so we can quickly store the state.
4652 (ApplyAttributes): Set the correct implementation flags
4653 for InternalCall methods.
4655 2001-12-29 Miguel de Icaza <miguel@ximian.com>
4657 * expression.cs (EmitCall): if a method is not virtual, then do
4658 not use callvirt on it.
4660 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
4661 user defined stuff) requires the use of stobj, which takes an
4662 address on the stack instead of an array and an index. So emit
4663 the Ldelema operation for it.
4665 (EmitStoreOpcode): Use stobj for valuetypes.
4667 (UnaryMutator.EmitCode): Use the right 1 value depending on
4668 whether we are dealing with int64/uint64, float or doubles.
4670 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
4671 constructors that I implemented last night.
4673 (Constructor.IsDefault): Fix to work properly for static
4676 * cs-parser.jay (CheckDef): report method signature errors.
4677 Update error number 103 to be 132.
4679 * decl.cs: New AdditionResult enumeration value: MethodExists.
4680 Although we do this check for methods later on in the semantic
4681 analysis, catching repeated default constructors is so easy that
4682 we catch these here.
4684 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
4687 (ParameterReference.EmitAssign, Emit): handle
4690 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
4691 (ArrayAccess.EmitStoreOpcode): ditto.
4693 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
4695 * expression.cs (MakeByteBlob): Complete all the missing types
4696 (uint, short, ushort, byte, sbyte)
4698 * class.cs: Only init instance field initializers on instance
4701 Rename `constructors' to instance_constructors.
4703 (TypeContainer.AddConstructor): Only add constructors to the list
4704 if it is not static.
4706 Make sure that we handle default_static_constructor independently
4707 everywhere where we handle instance_constructors
4709 2001-12-28 Miguel de Icaza <miguel@ximian.com>
4711 * class.cs: Do not lookup or create a base initializer for a
4714 (ConstructorInitializer.Resolve): use the proper type to lookup
4717 * cs-parser.jay: Report error 1585 (modifiers between type and name).
4719 * enum.cs, interface.cs: Remove CloseType, this is taken care by
4722 * decl.cs: CloseType is now an virtual method, the default
4723 implementation just closes this type.
4725 2001-12-28 Ravi Pratap <ravi@ximian.com>
4727 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
4728 to PreserveSig by default. Also emit HideBySig on such methods.
4730 Basically, set the defaults to standard values.
4732 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
4733 argument, if candidate is better, it can't be worse than the best !
4735 (Invocation): Re-write bits to differentiate between methods being
4736 applicable in their expanded form and their normal form - for params
4739 Get rid of use_standard everywhere as only standard conversions are allowed
4740 in overload resolution.
4742 More spec conformance.
4744 2001-12-27 Miguel de Icaza <miguel@ximian.com>
4746 * driver.cs: Add --timestamp, to see where the compiler spends
4749 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
4750 `this' in static code.
4752 (SimpleName.DoResolve): Implement in terms of a helper function
4753 that allows static-references to be passed upstream to
4756 (Expression.ResolveWithSimpleName): Resolve specially simple
4757 names when called by MemberAccess to implement the special
4760 (Expression.ImplicitReferenceConversion): Handle conversions from
4761 Null to reference types before others, as Null's type is
4764 * expression.cs (Invocation.EmitCall): Handle the special case of
4765 calling methods declared on a reference type from a ValueType
4766 (Base classes System.Object and System.Enum)
4768 (MemberAccess.Resolve): Only perform lookups on Enumerations if
4769 the left hand side is a TypeExpr, not on every enumeration.
4771 (Binary.Resolve): If types are reference types, then do a cast to
4772 object on operators != and == of both arguments.
4774 * typemanager.cs (FindMembers): Extract instance and static
4775 members if requested.
4777 * interface.cs (PopulateProperty): Use void_type instead of null
4778 as the return type for the setter method.
4780 (PopulateIndexer): ditto.
4782 2001-12-27 Ravi Pratap <ravi@ximian.com>
4784 * support.cs (ReflectionParameters): Fix minor bug where we
4785 were examining the wrong parameter for the ParamArray attribute.
4787 Cope with requests for the type of the parameter at position
4788 greater than the params parameter's. We now return the element
4789 type of the params array as that makes more sense.
4791 * expression.cs (Invocation.IsParamsMethodApplicable): Update
4792 accordingly as we no longer have to extract the element type
4795 (Invocation.OverloadResolve): Update.
4797 2001-12-27 Miguel de Icaza <miguel@ximian.com>
4799 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
4800 against IEnumerator, test whether the return value is a descendant
4801 of the IEnumerator interface.
4803 * class.cs (Indexer.Define): Use an auxiliary method to implement
4804 the other bits of the method definition. Begin support for
4805 explicit interface implementation.
4807 (Property.DefineMethod): Use TypeManager.void_type instead of null
4808 for an empty return value.
4810 2001-12-26 Miguel de Icaza <miguel@ximian.com>
4812 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
4813 dealing with a FieldExpr which is composed of a FieldBuilder, in
4814 the code path we did extract the constant, but we should have
4815 obtained the underlying value to be able to cast it (otherwise we
4816 end up in an infinite loop, this is what Ravi was running into).
4818 (ArrayCreation.UpdateIndices): Arrays might be empty.
4820 (MemberAccess.ResolveMemberAccess): Add support for section
4821 14.5.4.1 that deals with the special case of E.I when E is a type
4822 and something else, that I can be a reference to a static member.
4824 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
4825 handle a particular array type to create byte blobs, it is just
4826 something we dont generate byteblobs for.
4828 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
4831 * location.cs (Push): remove the key from the hashtable that we
4832 are about to add. This happens for empty files.
4834 * driver.cs: Dispose files after we have parsed them.
4836 (tokenize): new function that only runs the tokenizer on its
4837 input, for speed testing.
4839 2001-12-26 Ravi Pratap <ravi@ximian.com>
4841 * class.cs (Event.Define): Define the private field only if there
4842 are no accessors defined.
4844 * expression.cs (ResolveMemberAccess): If there is no associated
4845 field with the event, that means we have an event defined with its
4846 own accessors and we should flag error cs0070 since transforming
4847 ourselves into a field is not valid in that case.
4849 * ecore.cs (SimpleName.DoResolve): Same as above.
4851 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
4852 and charset to sane values.
4854 2001-12-25 Ravi Pratap <ravi@ximian.com>
4856 * assign.cs (DoResolve): Perform check on events only if they
4857 are being accessed outside the declaring type.
4859 * cs-parser.jay (event_declarations): Update rules to correctly
4860 set the type of the implicit parameter etc.
4862 (add_accessor, remove_accessor): Set current local parameters.
4864 * expression.cs (Binary): For delegate addition and subtraction,
4865 cast the return value from the method into the appropriate delegate
4868 2001-12-24 Ravi Pratap <ravi@ximian.com>
4870 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
4871 of these as the workaround is unnecessary.
4873 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
4874 delegate data - none of that is needed at all.
4876 Re-write bits to extract the instance expression and the delegate method
4879 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
4882 * attribute.cs (ApplyAttributes): New method to take care of common tasks
4883 of attaching attributes instead of duplicating code everywhere.
4885 * everywhere : Update code to do attribute emission using the above method.
4887 2001-12-23 Miguel de Icaza <miguel@ximian.com>
4889 * expression.cs (IsParamsMethodApplicable): if there are not
4890 parameters, return immediately.
4892 * ecore.cs: The 0 literal can be implicity converted to an enum
4895 (SimpleName.DoResolve): First lookup the type, then lookup the
4898 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
4899 want to get its address. If the InstanceExpression is not
4900 addressable, store the result in a temporary variable, then get
4903 * codegen.cs: Only display 219 errors on warning level or above.
4905 * expression.cs (ArrayAccess): Make it implement the
4906 IMemoryLocation interface.
4908 (Binary.DoResolve): handle the operator == (object a, object b)
4909 and operator != (object a, object b) without incurring into a
4910 BoxedCast (because 5 != o should never be performed).
4912 Handle binary enumerator operators.
4914 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
4915 value type, otherwise use Ldelem_ref.
4917 Use precomputed names;
4919 (AddressOf): Implement address of
4921 * cs-parser.jay (labeled_statement): Fix recursive block
4922 addition by reworking the production.
4924 * expression.cs (New.DoEmit): New has a special case:
4926 If we are dealing with a ValueType, we have a few
4927 situations to deal with:
4929 * The target of New is a ValueType variable, that is
4930 easy, we just pass this as the variable reference
4932 * The target of New is being passed as an argument,
4933 to a boxing operation or a function that takes a
4936 In this case, we need to create a temporary variable
4937 that is the argument of New.
4940 2001-12-23 Ravi Pratap <ravi@ximian.com>
4942 * rootcontext.cs (LookupType): Check that current_type is not null before
4943 going about looking at nested types.
4945 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
4946 not implement the IAssignMethod interface any more.
4948 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
4949 where we tranform them into FieldExprs if they are being resolved from within
4952 * ecore.cs (SimpleName.DoResolve): Do the same here.
4954 * assign.cs (DoResolve, Emit): Clean up code considerably.
4956 * ../errors/bug10.cs : Add.
4958 * ../errors/cs0070.cs : Add.
4960 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
4962 * assign.cs : Get rid of EventIsLocal everywhere.
4964 2001-12-23 Miguel de Icaza <miguel@ximian.com>
4966 * ecore.cs (ConvertIntLiteral): finished the implementation.
4968 * statement.cs (SwitchLabel): Convert the value we are using as a
4969 key before looking up the table.
4971 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4973 * codegen.cs (EmitTopBlock): Require a Location argument now.
4975 * cs-parser.jay (constructor_declarator): We need to setup
4976 current_local_parameters before we parse the
4977 opt_constructor_initializer, to allow the variables to be bound
4978 to the constructor arguments.
4980 * rootcontext.cs (LookupType): First lookup nested classes in our
4981 class and our parents before we go looking outside our class.
4983 * expression.cs (ConstantFold): Extract/debox the values at the
4986 * rootcontext.cs (EmitCode): Resolve the constants first before we
4987 resolve the types. This is not really needed, but it helps debugging.
4989 * statement.cs: report location.
4991 * cs-parser.jay: pass location to throw statement.
4993 * driver.cs: Small bug fix.
4995 * report.cs: Updated format to be 4-zero filled digits.
4997 2001-12-22 Ravi Pratap <ravi@ximian.com>
4999 * expression.cs (CheckIndices): Fix minor bug where the wrong
5000 variable was being referred to ;-)
5002 (DoEmit): Do not call EmitStaticInitializers when the
5003 underlying type is System.Object.
5005 2001-12-21 Ravi Pratap <ravi@ximian.com>
5007 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
5008 and do the usual workaround for SRE.
5010 * class.cs (MyEventBuilder.EventType): New member to get at the type
5011 of the event, quickly.
5013 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
5015 * assign.cs (Assign.DoResolve): Handle the case when the target
5016 is an EventExpr and perform the necessary checks.
5018 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
5021 (SimpleName.MemberStaticCheck): Include check for EventExpr.
5023 (EventExpr): Set the type in the constructor itself since we
5024 are meant to be born fully resolved.
5026 (EventExpr.Define): Revert code I wrote earlier.
5028 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
5029 instance expression is null. The instance expression is a This in that case
5030 or a null, depending on whether it is a static method or not.
5032 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
5033 refers to more than one method.
5035 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
5036 and accordingly flag errors.
5038 2001-12-21 Miguel de Icaza <miguel@ximian.com>
5040 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
5042 2001-12-22 Miguel de Icaza <miguel@ximian.com>
5044 * location.cs (ToString): Provide useful rutine.
5046 2001-12-21 Miguel de Icaza <miguel@ximian.com>
5048 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
5049 objects, return the actual integral boxed.
5051 * statement.cs (SwitchLabel): define an ILLabel for each
5054 (Switch.CheckSwitch): If the value is a Literal, extract
5055 the underlying literal.
5057 Also in the unused hashtable we had, add the SwitchLabel so we can
5058 quickly look this value up.
5060 * constant.cs: Implement a bunch of new constants. Rewrite
5061 Literal based on this. Made changes everywhere to adapt to this.
5063 * expression.cs (Expression.MakeByteBlob): Optimize routine by
5064 dereferencing array only once, and also copes with enumrations.
5066 bytes are two bytes wide, not one.
5068 (Cast): Perform constant conversions.
5070 * ecore.cs (TryImplicitIntConversion): Return literals instead of
5071 wrappers to the literals here.
5073 * expression.cs (DoNumericPromotions): long literals can converted
5074 to ulong implicity (this is taken care of elsewhere, but I was
5077 * ecore.cs (Expression.Literalize): Make the return type Literal,
5078 to improve type checking.
5080 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
5082 2001-12-20 Miguel de Icaza <miguel@ximian.com>
5084 * literal.cs: Revert code from ravi that checked the bounds. The
5085 bounds are sane by the definition of the type itself.
5087 * typemanager.cs: Fix implementation of ImplementsInterface. We
5088 need to actually look up in our parent hierarchy for interfaces
5091 * const.cs: Use the underlying type for enumerations
5093 * delegate.cs: Compute the basename for the delegate creation,
5094 that should fix the delegate test case, and restore the correct
5095 Type Lookup semantics in rootcontext
5097 * rootcontext.cs: Revert Ravi's last patch. The correct way of
5098 referencing a nested type with the Reflection API is using the "+"
5101 * cs-parser.jay: Do not require EOF token at the end.
5103 2001-12-20 Ravi Pratap <ravi@ximian.com>
5105 * rootcontext.cs (LookupType): Concatenate type names with
5106 a '.' instead of a '+' The test suite passes again.
5108 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
5109 field of the enumeration.
5111 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
5112 the case when the member is an EventExpr.
5114 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
5115 static has an associated instance expression.
5117 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
5119 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
5121 * class.cs (Event.Define): Register event and perform appropriate checks
5124 We define the Add and Remove methods even if the use provides none because
5125 in that case, we provide default implementations ourselves.
5127 Define a private field of the type of the event. This is done by the CSC compiler
5128 and we should be doing it too ;-)
5130 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
5131 More methods we use in code we generate.
5133 (multicast_delegate_type, delegate_type): Two separate types since the distinction
5136 (InitCoreTypes): Update accordingly for the above.
5138 * class.cs (Event.Emit): Generate code for default accessors that we provide
5140 (EmitDefaultMethod): Do the job in the above.
5142 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
5145 2001-12-20 Miguel de Icaza <miguel@ximian.com>
5147 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
5148 builders even if we were missing one.
5150 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
5151 pass the Basename as our class name instead of the Name. The
5152 basename will be correctly composed for us.
5154 * parameter.cs (Paramters): Now takes a Location argument.
5156 * decl.cs (DeclSpace.LookupType): Removed convenience function and
5157 make all the code call directly LookupType in RootContext and take
5158 this chance to pass the Location information everywhere.
5160 * Everywhere: pass Location information.
5162 2001-12-19 Miguel de Icaza <miguel@ximian.com>
5164 * class.cs (Constructor.Define): Updated way of detecting the
5165 length of the parameters.
5167 (TypeContainer.DefineType): Use basename as the type name for
5170 (TypeContainer.Define): Do not recursively define types here, as
5171 definition is taken care in order by the RootContext.
5173 * tree.cs: Keep track of namespaces in a per-file basis.
5175 * parameter.cs (Parameter.ComputeSignature): Update to use
5178 (Parameters.GetSignature): ditto.
5180 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
5181 instead of a TypeContainer.
5183 (Interface.SemanticAnalysis): Use `this' instead of our parent to
5184 resolve names. Because we need to be resolve in our context, not
5187 * driver.cs: Implement response files.
5189 * class.cs (TypeContainer.DefineType): If we are defined, do not
5192 (Event.Emit): Emit the code for add/remove handlers.
5193 (Event.Define): Save the MethodBuilders for add/remove.
5195 * typemanager.cs: Use pair here too.
5197 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
5198 DictionaryEntry requires the first argument to be non-null.
5200 (enum_declaration): Compute full name for registering the
5203 (delegate_declaration): Instead of using
5204 formal_parameter_list, use opt_formal_parameter_list as the list
5207 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
5208 (EventParsing): New property that controls whether `add' and
5209 `remove' are returned as tokens or identifiers (for events);
5211 2001-12-19 Ravi Pratap <ravi@ximian.com>
5213 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
5214 use MyEventBuilder only and let it wrap the real builder for us.
5216 (MyEventBuilder): Revamp constructor etc.
5218 Implement all operations that we perform on EventBuilder in precisely the same
5221 (FindMembers): Update to use the EventBuilder member.
5223 (Event.Emit): Update accordingly.
5225 2001-12-18 Ravi Pratap <ravi@ximian.com>
5227 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
5228 by calling the appropriate methods.
5230 (GetCustomAttributes): Make stubs as they cannot possibly do anything
5233 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
5235 2001-12-17 Ravi Pratap <ravi@ximian.com>
5237 * delegate.cs (Delegate.Populate): Check that the return type
5238 and various parameters types are indeed accessible.
5240 * class.cs (Constructor.Define): Same here.
5242 (Field.Define): Ditto.
5244 (Event.Define): Ditto.
5246 (Operator.Define): Check that the underlying Method defined itself
5247 correctly - so it's MethodBuilder should not be null.
5249 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
5250 expression happens to be null.
5252 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
5253 members but as of now we don't seem to be able to do anything really useful with it.
5255 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
5256 not the EventBuilder.
5258 2001-12-18 Miguel de Icaza <miguel@ximian.com>
5260 * cs-tokenizer.cs: Add support for defines.
5261 Add support for #if, #elif, #else, #endif
5263 (eval_var): evaluates a variable.
5264 (eval): stubbed for evaluating functions.
5266 * cs-parser.jay: Pass the defines information
5268 * driver.cs: Add --define command line option.
5270 * decl.cs: Move MemberCore here.
5272 Make it the base class for DeclSpace. This allows us to catch and
5273 report 108 and 109 for everything now.
5275 * class.cs (TypeContainer.Define): Extract all the members
5276 before populating and emit the warning 108 (new keyword required
5277 to override) instead of having each member implement this.
5279 (MemberCore.Define): New abstract method, we will be using this in
5280 the warning reporting engine in Populate.
5282 (Operator.Define): Adjust to new MemberCore protocol.
5284 * const.cs (Const): This does not derive from Expression, it is a
5285 temporary object we use to create fields, it is a MemberCore.
5287 * class.cs (Method.Define): Allow the entry point to be in a
5290 * driver.cs: Rewrite the argument handler to clean it up a bit.
5292 * rootcontext.cs: Made it just an auxiliary namespace feature by
5293 making everything static.
5295 * driver.cs: Adapt code to use RootContext type name instead of
5298 * delegate.cs: Remove RootContext argument.
5300 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
5303 * class.cs (Event.Define): The lookup can fail.
5305 * cs-tokenizer.cs: Begin implementation of pre-procesor.
5307 * expression.cs: Resolve the this instance before invoking the code.
5309 2001-12-17 Miguel de Icaza <miguel@ximian.com>
5311 * cs-parser.jay: Add a production in element_access that allows
5312 the thing to become a "type" reference. This way we can parse
5313 things like "(string [])" as a type.
5315 Note that this still does not handle the more complex rules of
5319 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
5321 * ecore.cs: (CopyNewMethods): new utility function used to
5322 assemble the list of methods from running FindMembers.
5324 (MemberLookup): Rework FindMembers so that
5326 2001-12-16 Miguel de Icaza <miguel@ximian.com>
5328 * class.cs (TypeContainer): Remove Delegates who fail to be
5331 * delegate.cs (Populate): Verify that we dont get null return
5332 values. TODO: Check for AsAccessible.
5334 * cs-parser.jay: Use basename to emit error 574 (destructor should
5335 have the same name as container class), not the full name.
5337 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
5338 possible representation.
5340 Also implements integer type suffixes U and L.
5342 2001-12-15 Miguel de Icaza <miguel@ximian.com>
5344 * expression.cs (ArrayCreation.DoResolve): We need to do the
5345 argument resolution *always*.
5347 * decl.cs: Make this hold the namespace. Hold the root context as
5349 (LookupType): Move here.
5351 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
5353 * location.cs (Row, Name): Fixed the code, it was always returning
5354 references to the first file.
5356 * interface.cs: Register properties defined through interfaces.
5358 * driver.cs: Add support for globbing on the command line
5360 * class.cs (Field): Make it derive from MemberCore as well.
5363 2001-12-15 Ravi Pratap <ravi@ximian.com>
5365 * class.cs (Event::Define): Check that the type of the event is a delegate
5366 type else flag error #66.
5368 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
5371 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
5372 values of EntryPoint, CharSet etc etc.
5374 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
5376 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
5377 be null and we should ignore this. I am not sure if this is really clean. Apparently,
5378 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
5379 which needs this to do its work.
5381 * ../errors/cs0066.cs : Add.
5383 2001-12-14 Miguel de Icaza <miguel@ximian.com>
5385 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
5388 * class.cs: (MethodSignature.MethodSignature): Removed hack that
5389 clears out the parameters field.
5390 (MemberSignatureCompare): Cleanup
5392 (MemberCore): New base class used to share code between MethodCore
5395 (RegisterRequiredImplementations) BindingFlags.Public requires
5396 either BindingFlags.Instace or Static. Use instance here.
5398 (Property): Refactored code to cope better with the full spec.
5400 * parameter.cs (GetParameterInfo): Return an empty array instead
5403 * class.cs (Property): Abstract or extern properties have no bodies.
5405 * parameter.cs (GetParameterInfo): return a zero-sized array.
5407 * class.cs (TypeContainer.MethodModifiersValid): Move all the
5408 method modifier validation to the typecontainer so we can reuse
5411 (MethodCore.ParameterTypes): return an empty sized array of types.
5413 (Property.Define): Test property modifier validity.
5415 Add tests for sealed/override too.
5417 (Method.Emit): abstract or extern methods have no bodies.
5419 2001-12-14 Ravi Pratap <ravi@ximian.com>
5421 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
5424 (Method::Define, ::Emit): Modify accordingly.
5426 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
5428 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
5430 * makefile: Pass in /unsafe.
5432 2001-12-13 Miguel de Icaza <miguel@ximian.com>
5434 * class.cs (MakeKey): Kill routine.
5436 * class.cs (TypeContainer.Define): Correctly define explicit
5437 method implementations (they require the full interface name plus
5440 * typemanager.cs: Deply the PtrHashtable here and stop using the
5441 lame keys. Things work so much better.
5443 This of course broke everyone who depended on `RegisterMethod' to
5444 do the `test for existance' test. This has to be done elsewhere.
5446 * support.cs (PtrHashtable): A hashtable that avoid comparing with
5447 the object stupid Equals method (because, that like fails all over
5448 the place). We still do not use it.
5450 * class.cs (TypeContainer.SetRequiredInterface,
5451 TypeContainer.RequireMethods): Killed these two routines and moved
5452 all the functionality to RegisterRequiredImplementations.
5454 (TypeContainer.RegisterRequiredImplementations): This routine now
5455 registers all the implementations required in an array for the
5456 interfaces and abstract methods. We use an array of structures
5457 which can be computed ahead of time to reduce memory usage and we
5458 also assume that lookups are cheap as most classes will not
5459 implement too many interfaces.
5461 We also avoid creating too many MethodSignatures.
5463 (TypeContainer.IsInterfaceMethod): Update and optionally does not
5464 clear the "pending" bit if we find that there are problems with
5467 (TypeContainer.VerifyPendingMethods): Update to report errors of
5468 methods that look like implementations but are not.
5470 (TypeContainer.Define): Add support for explicit interface method
5473 2001-12-12 Miguel de Icaza <miguel@ximian.com>
5475 * typemanager.cs: Keep track of the parameters here instead of
5476 being a feature of the TypeContainer.
5478 * class.cs: Drop the registration of parameters here, as
5479 InterfaceMethods are also interface declarations.
5481 * delegate.cs: Register methods with the TypeManager not only with
5482 the TypeContainer. This code was buggy.
5484 * interface.cs: Full registation here.
5486 2001-12-11 Miguel de Icaza <miguel@ximian.com>
5488 * expression.cs: Remove reducer for binary expressions, it can not
5491 * const.cs: Put here the code that used to go into constant.cs
5493 * constant.cs: Put here the code for constants, this is a new base
5496 * literal.cs: Make Literal derive from Constant.
5498 2001-12-09 Miguel de Icaza <miguel@ximian.com>
5500 * statement.cs (Return.Emit): Report error 157 if the user
5501 attempts to return from a finally block.
5503 (Return.Emit): Instead of emitting a return, jump to the end of
5506 * codegen.cs (EmitContext): ReturnValue, ReturnLabel: new
5507 LocalBuilder to store the result of the function. ReturnLabel is
5508 the target where we jump.
5511 2001-12-09 Radek Doulik <rodo@ximian.com>
5513 * cs-parser.jay: remember alias in current namespace
5515 * ecore.cs (SimpleName::DoResolve): use aliases for types or
5518 * class.cs (LookupAlias): lookup alias in my_namespace
5520 * namespace.cs (UsingAlias): add alias, namespace_or_type pair to
5522 (LookupAlias): lookup alias in this and if needed in parent
5525 2001-12-08 Miguel de Icaza <miguel@ximian.com>
5529 * rootcontext.cs: (ModuleBuilder) Made static, first step into
5530 making things static. I need this to avoid passing the
5531 TypeContainer when calling ParameterType.
5533 * support.cs (InternalParameters.ParameterType): Remove ugly hack
5534 that did string manipulation to compute the type and then call
5535 GetType. Use Parameter.ParameterType instead.
5537 * cs-tokenizer.cs: Consume the suffix for floating values.
5539 * expression.cs (ParameterReference): figure out whether this is a
5540 reference parameter or not. Kill an extra variable by computing
5541 the arg_idx during emission.
5543 * parameter.cs (Parameters.GetParameterInfo): New overloaded
5544 function that returns whether a parameter is an out/ref value or not.
5546 (Parameter.ParameterType): The type of the parameter (base,
5547 without ref/out applied).
5549 (Parameter.Resolve): Perform resolution here.
5550 (Parameter.ExternalType): The full type (with ref/out applied).
5552 * statement.cs (Using.Emit, Using.EmitExpression): Implement
5553 support for expressions on the using statement.
5555 2001-12-07 Miguel de Icaza <miguel@ximian.com>
5557 * statement.cs (Using.EmitLocalVariableDecls): Split the
5558 localvariable handling of the using statement.
5560 (Block.EmitMeta): Keep track of variable count across blocks. We
5561 were reusing slots on separate branches of blocks.
5563 (Try.Emit): Emit the general code block, we were not emitting it.
5565 Check the type of the declaration to be an IDisposable or
5566 something that can be implicity converted to it.
5568 Emit conversions if required.
5570 * ecore.cs (EmptyExpression): New utility class.
5571 (Expression.ImplicitConversionExists): New utility function.
5573 2001-12-06 Miguel de Icaza <miguel@ximian.com>
5575 * statement.cs (Using): Implement.
5577 * expression.cs (LocalVariableReference): Support read only variables.
5579 * statement.cs: Remove the explicit emit for the Leave opcode.
5580 (VariableInfo): Add a readonly field.
5582 2001-12-05 Miguel de Icaza <miguel@ximian.com>
5584 * ecore.cs (ConvCast): new class used to encapsulate the various
5585 explicit integer conversions that works in both checked and
5588 (Expression.ConvertNumericExplicit): Use new ConvCast class to
5589 properly generate the overflow opcodes.
5591 2001-12-04 Miguel de Icaza <miguel@ximian.com>
5593 * statement.cs: The correct type for the EmptyExpression is the
5594 element_type, not the variable type. Ravi pointed this out.
5596 2001-12-04 Ravi Pratap <ravi@ximian.com>
5598 * class.cs (Method::Define): Handle PInvoke methods specially
5599 by using DefinePInvokeMethod instead of the usual one.
5601 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
5602 above to do the task of extracting information and defining the method.
5604 2001-12-04 Ravi Pratap <ravi@ximian.com>
5606 * expression.cs (ArrayCreation::EmitStaticInitializers): Get rid
5607 of the condition for string type.
5609 (Emit): Move that here.
5611 (ArrayCreation::CheckIndices): Keep string literals in their expression
5614 (EmitDynamicInitializers): Handle strings appropriately.
5616 2001-12-04 Miguel de Icaza <miguel@ximian.com>
5618 * codegen.cs (EmitContext): Replace multiple variables with a
5619 single pointer to the current Switch statement.
5621 * statement.cs (GotoDefault, Switch): Adjust to cleaned up
5624 2001-12-03 Miguel de Icaza <miguel@ximian.com>
5628 * statement.cs (GotoDefault), cs-parser.jay: Implement `goto
5631 (Foreach.Emit): Foreach on arrays was not setting
5632 up the loop variables (for break/continue).
5634 (GotoCase): Semi-implented.
5636 2001-12-03 Ravi Pratap <ravi@ximian.com>
5638 * attribute.cs (CheckAttribute): Handle system attributes by using
5639 Attribute.GetAttributes to examine information we need.
5641 (GetValidPlaces): Same here.
5643 * class.cs (Method::Define): Catch invalid use of extern and abstract together.
5645 * typemanager.cs (dllimport_type): Core type for System.DllImportAttribute.
5647 * class.cs (Method.IsPinvoke): Used to determine if we are a PInvoke method.
5649 (Method::Define): Set appropriate flags if we have a DllImport attribute.
5651 (Method::Emit): Handle the case when we are a PInvoke method.
5653 2001-12-03 Miguel de Icaza <miguel@ximian.com>
5655 * expression.cs: Use ResolveWithSimpleName on compound names.
5657 2001-12-02 Ravi Pratap <ravi@ximian.com>
5659 * constant.cs (EmitConstant): Make sure we resolve the associated expression
5660 before trying to reduce it.
5662 * typemanager.cs (RegisterConstant, LookupConstant): Implement.
5664 * constant.cs (LookupConstantValue): Implement.
5666 (EmitConstant): Use the above in emitting the constant.

5861 allowed a limited set of types to be handled. Now we take a
5862 unary_expression and we resolve to a type during semantic
5865 Use the grammar productions from Rhys to handle casts (this is
5866 not complete like Rhys syntax yet, we fail to handle that corner
5867 case that C# has regarding (-x), but we will get there.
5869 2001-11-22 Ravi Pratap <ravi@ximian.com>

5886 (MemberAccess::DoResolve): Fix the code which handles Enum literals to set
5887 the correct type etc.
5889 (ConvertExplicit): Handle Enum types by examining the underlying type.

5911 (Expression.ConvertExplicit): Add explicit type conversions done
5914 (Expression.ImplicitNumericConversion): Oops, forgot to test for

5918 2001-11-21 Miguel de Icaza <miguel@ximian.com>
5920 * cs-parser.jay (for_statement): Reworked the way For works: now
5921 we declare manually any variables that are introduced in
5922 for_initializer to solve the problem of having out-of-band code
5923 emition (that is what got for broken).
5925 (declaration_statement): Perform the actual variable declaration
5926 that used to be done in local_variable_declaration here.
5928 (local_variable_declaration): Do not declare anything, just pass
5929 the information on a DictionaryEntry

6006 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
6007 function used to return a static Parameters structure. Used for

6012 2001-11-15 Ravi Pratap <ravi@ximian.com>
6014 * interface.cs : Default modifier is private, not public. The

6026 of $$ to get at the location.
6028 (indexer_declaration): Similar stuff.
6032 * class.cs (Property): Register parameters for the Get and Set methods
6033 if they exist. Test 23 passes again.

6040 IndexOutOfRangeException.
6042 * class.cs (Property::Define): Register property using TypeManager.RegisterProperty

6053 2001-11-09 Miguel de Icaza <miguel@ximian.com>

6079 location where this argument is used. Notice that this is not
6080 part of the "Argument" class as to reduce the size of the
6081 structure (we know the approximate location anyways).

6084 complain with a 206.
6086 (Argument.Emit): Emit addresses of variables.

6117 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
6118 enumerations that are used in heavily used structures derive from

6121 home without adult supervision.
6123 * expression.cs (UnaryMutator): New class, used to handle ++ and
6124 -- separatedly from the other unary operators. Cleans up the
6125 code, and kills the ExpressionStatement dependency in Unary.
6127 (Unary): Removed `method' and `Arguments' from this class, making
6128 it smaller, and moving it all to SimpleCall, so I can reuse this
6129 code in other locations and avoid creating a lot of transient data
6130 strucutres when not required.
6132 * cs-parser.jay: Adjust for new changes.

6204 * expression.cs (MemberAccess.DoResolve): Adjust code to obtain the value
6205 of a fieldinfo using the above, when dealing with a FieldBuilder.

6252 2001-11-09 Miguel de Icaza <miguel@ximian.com>
6254 * cs-parser.jay: A for_initializer if is a
6255 local_variable_declaration really ammount to have an implicit
6256 block with the variable declaration and no initializer for for.

6291 Emit method everywhere.
6293 * enum.cs (Enum): Revamp to use the same definition semantics as delegates so

6299 * typemanager.cs (AddEnumType): To keep track of enum types separately.

6368 IStackStore as the order in which arguments are passed reflects
6371 * assign.cs: Instead of using expr.ExprClass to select the way of
6372 assinging, probe for the IStackStore/IAssignMethod interfaces.

7083 * rootcontext.cs: Deal with field-less struct types correctly now
7084 by passing the size option to Define Type.
7086 * class.cs: Removed hack that created one static field.
7088 2001-10-07 Miguel de Icaza <miguel@ximian.com>
7090 * statement.cs: Moved most of the code generation here.
7092 2001-10-09 Ravi Pratap <ravi@ximian.com>
7094 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't

7102 * expression.cs (ElementAccess::DoResolve): Remove my crap code
7103 and start performing checks according to the spec.
7105 2001-10-07 Ravi Pratap <ravi@ximian.com>
7107 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
7108 rank_specifiers instead.
7110 (rank_specifiers): Change the order in which the rank specifiers are stored
7112 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
7114 * expression.cs (ElementAccess): Implement the LValue interface too.
7116 2001-10-06 Ravi Pratap <ravi@ximian.com>
7118 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
7119 except that user defined conversions are not included.
7121 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
7122 perform the conversion of the return type, if necessary.
7124 (New::DoResolve): Check whether we are creating an array or an object
7125 and accordingly do the needful.
7127 (New::Emit): Same here.
7129 (New::DoResolve): Implement guts of array creation.
7131 (New::FormLookupType): Helper function.
7133 2001-10-07 Miguel de Icaza <miguel@ximian.com>

7142 * class.cs: Catch static methods having the flags override,
7143 virtual or abstract.
7145 * expression.cs (UserCast): This user cast was not really doing
7146 what it was supposed to do. Which is to be born in fully resolved
7147 state. Parts of the resolution were being performed at Emit time!
7151 2001-10-05 Miguel de Icaza <miguel@ximian.com>
7153 * expression.cs: Implicity convert the result from UserCast.
7155 2001-10-05 Ravi Pratap <ravi@ximian.com>
7157 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
7158 prevented it from working correctly.

7161 merely ConvertImplicit.
7163 2001-10-05 Miguel de Icaza <miguel@ximian.com>
7165 * typemanager.cs: Make the LookupTypeContainer function static,
7166 and not per-instance.
7168 * class.cs: Make static FindMembers (the one that takes a Type
7171 * codegen.cs: Add EmitForeach here.
7173 * cs-parser.jay: Make foreach a toplevel object instead of the
7174 inline expansion, as we need to perform semantic analysis on it.
7176 2001-10-05 Ravi Pratap <ravi@ximian.com>
7178 * expression.cs (Expression::ImplicitUserConversion): Rename to
7179 UserDefinedConversion.
7181 (Expression::UserDefinedConversion): Take an extra argument specifying
7182 whether we look for explicit user conversions too.

7193 * expression.cs (Cast): Record location info.
7195 (Expression::ConvertExplicit): Take location argument.
7197 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
7198 to determine if we are doing explicit conversions.
7200 (UserCast::Emit): Update accordingly.
7202 (Expression::ConvertExplicit): Report an error if everything fails.
7204 * ../errors/cs0030.cs : Add.
7206 2001-10-04 Miguel de Icaza <miguel@ximian.com>
7208 * modifiers.cs: If the ABSTRACT keyword is present, also set the
7209 virtual and newslot bits.
7211 * class.cs (TypeContainer::RegisterRequiredImplementations):
7212 Record methods we need.
7214 (TypeContainer::MakeKey): Helper function to make keys for
7215 MethodBases, since the Methodbase key is useless.
7217 (TypeContainer::Populate): Call RegisterRequiredImplementations
7218 before defining the methods.
7220 Create a mapping for method_builders_to_methods ahead of time
7221 instead of inside a tight loop.
7223 (::RequireMethods): Accept an object as the data to set into the
7224 hashtable so we can report interface vs abstract method mismatch.
7226 2001-10-03 Miguel de Icaza <miguel@ximian.com>
7228 * report.cs: Make all of it static.
7230 * rootcontext.cs: Drop object_type and value_type computations, as
7231 we have those in the TypeManager anyways.
7233 Drop report instance variable too, now it is a global.
7235 * driver.cs: Use try/catch on command line handling.
7237 Add --probe option to debug the error reporting system with a test
7240 * report.cs: Add support for exiting program when a probe
7241 condition is reached.
7243 2001-10-03 Ravi Pratap <ravi@ximian.com>
7245 * expression.cs (Binary::DoNumericPromotions): Fix the case when
7246 we do a forcible conversion regardless of type, to check if
7247 ForceConversion returns a null.
7249 (Binary::error19): Use location to report error.
7251 (Unary::error23): Use location here too.
7253 * ../errors/cs0019.cs : Check in.
7255 * ../errors/cs0023.cs : Check in.
7257 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
7258 case of a non-null MethodInfo object with a length of 0 !
7260 (Binary::ResolveOperator): Flag error if overload resolution fails to find
7261 an applicable member - according to the spec :-)
7262 Also fix logic to find members in base types.
7264 (Unary::ResolveOperator): Same here.
7266 (Unary::report23): Change name to error23 and make first argument a TypeContainer
7267 as I was getting thoroughly confused between this and error19 :-)
7269 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
7270 (::FindMostEncompassedType): Implement.
7271 (::FindMostEncompassingType): Implement.
7272 (::StandardConversionExists): Implement.
7274 (UserImplicitCast): Re-vamp. We now need info about most specific
7275 source and target types so that we can do the necessary conversions.
7277 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
7278 mathematical union with no duplicates.
7280 2001-10-03 Miguel de Icaza <miguel@ximian.com>
7282 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
7283 in order from base classes to child classes, so that we can in
7284 child classes look up in our parent for method names and
7285 attributes (required for handling abstract, virtual, new, override
7286 constructs: we need to instrospect our base class, and if we dont
7287 populate the classes in order, the introspection might be
7288 incorrect. For example, a method could query its parent before
7289 the parent has any methods and would determine that the parent has
7290 no abstract methods (while it could have had them)).
7292 (RootContext::CreateType): Record the order in which we define the
7295 2001-10-02 Miguel de Icaza <miguel@ximian.com>
7297 * class.cs (TypeContainer::Populate): Also method definitions can
7298 fail now, keep track of this.
7300 (TypeContainer::FindMembers): Implement support for
7301 DeclaredOnly/noDeclaredOnly flag.
7303 (Constructor::Emit) Return the ConstructorBuilder.
7305 (Method::Emit) Return the MethodBuilder.
7306 Check for abstract or virtual methods to be public.
7308 * rootcontext.cs (RootContext::CreateType): Register all the
7309 abstract methods required for the class to be complete and the
7310 interface methods that must be implemented.
7312 * cs-parser.jay: Report error 501 (method requires body if it is
7313 not marked abstract or extern).
7315 * expression.cs (TypeOf::Emit): Implement.
7317 * typemanager.cs: runtime_handle_type, new global type.
7319 * class.cs (Property::Emit): Generate code for properties.
7321 2001-10-02 Ravi Pratap <ravi@ximian.com>
7323 * expression.cs (Unary::ResolveOperator): Find operators on base type
7324 too - we now conform exactly to the spec.
7326 (Binary::ResolveOperator): Same here.
7328 * class.cs (Operator::Define): Fix minor quirk in the tests.
7330 * ../errors/cs0215.cs : Added.
7332 * ../errors/cs0556.cs : Added.
7334 * ../errors/cs0555.cs : Added.
7336 2001-10-01 Miguel de Icaza <miguel@ximian.com>
7338 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
7339 single integer which is really efficient
7341 2001-10-01 Ravi Pratap <ravi@ximian.com>
7343 * expression.cs (Expression::ImplicitUserConversion): Use location
7344 even in the case when we are examining True operators.
7346 * class.cs (Operator::Define): Perform extensive checks to conform
7347 with the rules for operator overloading in the spec.
7349 * expression.cs (Expression::ImplicitReferenceConversion): Implement
7350 some of the other conversions mentioned in the spec.
7352 * typemanager.cs (array_type): New static member for the System.Array built-in
7355 (cloneable_interface): For System.ICloneable interface.
7357 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
7358 we start resolving the tree and populating types.
7360 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
7362 2001-10-01 Miguel de Icaza <miguel@ximian.com>
7364 * expression.cs (Expression::ExprClassFromMemberInfo,
7365 Expression::Literalize): Create literal expressions from
7366 FieldInfos which are literals.
7368 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
7369 type casts, because they were wrong. The test suite in tests
7372 (ImplicitNumericConversion): ushort to ulong requires a widening
7375 Int32 constant to long requires widening cast as well.
7377 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
7378 for integers because the type on the stack is not i4.
7380 2001-09-30 Miguel de Icaza <miguel@ximian.com>
7382 * expression.cs (report118): require location argument.
7384 * parameter.cs: Do not dereference potential null value.
7386 * class.cs: Catch methods that lack the `new' keyword when
7387 overriding a name. Report warnings when `new' is used without
7388 anything being there to override.
7390 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
7392 * class.cs: Only add constructor to hashtable if it is non-null
7393 (as now constructors can fail on define).
7395 (TypeManager, Class, Struct): Take location arguments.
7397 Catch field instance initialization in structs as errors.
7399 accepting_filter: a new filter for FindMembers that is static so
7400 that we dont create an instance per invocation.
7402 (Constructor::Define): Catch errors where a struct constructor is
7405 * cs-parser.jay: Pass location information for various new
7408 * delegate.cs (Delegate): take a location argument.
7410 * driver.cs: Do not call EmitCode if there were problesm in the
7411 Definition of the types, as many Builders wont be there.
7413 * decl.cs (Decl::Decl): Require a location argument.
7415 * cs-tokenizer.cs: Handle properly hex constants that can not fit
7416 into integers, and find the most appropiate integer for it.
7418 * literal.cs: Implement ULongLiteral.
7420 * rootcontext.cs: Provide better information about the location of
7421 failure when CreateType fails.
7423 2001-09-29 Miguel de Icaza <miguel@ximian.com>
7425 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
7428 * expression.cs (Binary::CheckShiftArguments): Add missing type
7430 (Binary::ResolveOperator): Add type to the logical and and logical
7431 or, Bitwise And/Or and Exclusive Or code paths, it was missing
7434 (Binary::DoNumericPromotions): In the case where either argument
7435 is ulong (and most signed types combined with ulong cause an
7436 error) perform implicit integer constant conversions as well.
7438 2001-09-28 Miguel de Icaza <miguel@ximian.com>
7440 * expression.cs (UserImplicitCast): Method should always be
7442 (Invocation::BetterConversion): Simplified test for IntLiteral.
7444 (Expression::ImplicitNumericConversion): Split this routine out.
7445 Put the code that performs implicit constant integer conversions
7448 (Expression::Resolve): Become a wrapper around DoResolve so we can
7449 check eclass and type being set after resolve.
7451 (Invocation::Badness): Remove this dead function
7453 (Binary::ResolveOperator): Do not compute the expensive argumnets
7454 unless we have a union for it.
7456 (Probe::Emit): Is needs to do an isinst and then
7457 compare against null.
7459 (::CanConvert): Added Location argument. If the Location argument
7460 is null (Location.Null), then we do not report errors. This is
7461 used by the `probe' mechanism of the Explicit conversion. We do
7462 not want to generate an error for something that the user
7463 explicitly requested to be casted. But the pipeline for an
7464 explicit cast first tests for potential implicit casts.
7466 So for now, if the Location is null, it means `Probe only' to
7467 avoid adding another argument. Might have to revise this
7470 (ClassCast): New class used to type cast objects into arbitrary
7471 classes (used in Explicit Reference Conversions).
7473 Implement `as' as well.
7475 Reverted all the patches from Ravi below: they were broken:
7477 * The use of `level' as a mechanism to stop recursive
7478 invocations is wrong. That was there just to catch the
7479 bug with a strack trace but not as a way of addressing
7482 To fix the problem we have to *understand* what is going
7483 on and the interactions and come up with a plan, not
7484 just get things going.
7486 * The use of the type conversion cache that I proposed
7487 last night had an open topic: How does this work across
7488 protection domains. A user defined conversion might not
7489 be public in the location where we are applying the
7490 conversion, a different conversion might be selected
7491 (ie, private A->B (better) but public B->A (worse),
7492 inside A, A->B applies, but outside it, B->A will
7495 * On top of that (ie, even if the above is solved),
7496 conversions in a cache need to be abstract. Ie, `To
7497 convert from an Int to a Short use an OpcodeCast', not
7498 `To convert from an Int to a Short use the OpcodeCast on
7499 the variable 5' (which is what this patch was doing).
7501 2001-09-28 Ravi Pratap <ravi@ximian.com>
7503 * expression.cs (Invocation::ConversionExists): Re-write to use
7504 the conversion cache
7506 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
7507 cache all conversions done, not just user-defined ones.
7509 (Invocation::BetterConversion): The real culprit. Use ConversionExists
7510 to determine if a conversion exists instead of acutually trying to
7511 perform the conversion. It's faster too.
7513 (Expression::ConvertExplicit): Modify to use ConversionExists to check
7514 and only then attempt the implicit conversion.
7516 2001-09-28 Ravi Pratap <ravi@ximian.com>
7518 * expression.cs (ConvertImplicit): Use a cache for conversions
7519 already found. Check level of recursion and bail out if necessary.
7521 2001-09-28 Miguel de Icaza <miguel@ximian.com>
7523 * typemanager.cs (string_concat_string_string, string_concat_object_object):
7524 Export standard methods that we expect for string operations.
7526 * statement.cs (Block::UsageWarning): Track usage of variables and
7527 report the errors for not used variables.
7529 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
7532 2001-09-27 Miguel de Icaza <miguel@ximian.com>
7534 * codegen.cs: remove unnneded code
7536 * expression.cs: Removed BuiltinTypeAccess class
7538 Fix the order in which implicit conversions are
7541 The previous fixed dropped support for boxed conversions (adding a
7542 test to the test suite now)
7544 (UserImplicitCast::CanConvert): Remove test for source being null,
7545 that code is broken. We should not feed a null to begin with, if
7546 we do, then we should track the bug where the problem originates
7547 and not try to cover it up here.
7549 Return a resolved expression of type UserImplicitCast on success
7550 rather than true/false. Ravi: this is what I was talking about,
7551 the pattern is to use a static method as a "constructor" for
7554 Also, do not create arguments until the very last minute,
7555 otherwise we always create the arguments even for lookups that
7556 will never be performed.
7558 (UserImplicitCast::Resolve): Eliminate, objects of type
7559 UserImplicitCast are born in a fully resolved state.
7561 * typemanager.cs (InitCoreTypes): Init also value_type
7564 * expression.cs (Cast::Resolve): First resolve the child expression.
7566 (LValue): Add new method AddressOf to be used by
7569 Change the argument of Store to take an EmitContext instead of an
7570 ILGenerator, because things like FieldExpr need to be able to call
7571 their children expression to generate the instance code.
7573 (Expression::Error, Expression::Warning): Sugar functions for
7576 (Expression::MemberLookup): Accept a TypeContainer instead of a
7577 Report as the first argument.
7579 (Expression::ResolvePrimary): Killed. I still want to improve
7580 this as currently the code is just not right.
7582 (Expression::ResolveMemberAccess): Simplify, but it is still
7585 (Unary::Resolve): Catch errors in AddressOf operators.
7587 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
7588 index to a byte for the short-version, or the compiler will choose
7589 the wrong Emit call, which generates the wrong data.
7591 (ParameterReference::Emit, ::Store): same.
7593 (FieldExpr::AddressOf): Implement.
7595 * typemanager.cs: TypeManager: made public variable instead of
7598 * driver.cs: document --fatal.
7600 * report.cs (ErrorMessage, WarningMessage): new names for the old
7601 Error and Warning classes.
7603 * cs-parser.jay (member_access): Turn built-in access to types
7604 into a normal simplename
7606 2001-09-27 Ravi Pratap <ravi@ximian.com>
7608 * expression.cs (Invocation::BetterConversion): Fix to cope
7609 with q being null, since this was introducing a bug.
7611 * expression.cs (ConvertImplicit): Do built-in conversions first.
7613 2001-09-27 Ravi Pratap <ravi@ximian.com>
7615 * expression.cs (UserImplicitCast::Resolve): Fix bug.
7617 2001-09-27 Ravi Pratap <ravi@ximian.com>
7619 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
7620 I had introduced long ago (what's new ?).
7622 * expression.cs (UserImplicitCast::CanConvert): Static method to do
7623 the work of all the checking.
7624 (ConvertImplicit): Call CanConvert and only then create object if necessary.
7625 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
7627 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
7628 that is the right way.
7630 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
7631 overloading resolution. Use everywhere instead of cutting and pasting code.
7633 (Binary::ResolveOperator): Use MakeUnionSet.
7635 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
7636 we have to convert to bool types. Not complete yet.
7638 2001-09-27 Miguel de Icaza <miguel@ximian.com>
7640 * typemanager.cs (TypeManager::CSharpName): support ushort.
7642 * expression.cs (Expression::TryImplicitIntConversion): Attempts
7643 to provide an expression that performsn an implicit constant int
7644 conversion (section 6.1.6).
7645 (Expression::ConvertImplicitRequired): Reworked to include
7646 implicit constant expression conversions.
7648 (Expression::ConvertNumericExplicit): Finished.
7650 (Invocation::Emit): If InstanceExpression is null, then it means
7651 that we perform a call on this.
7653 2001-09-26 Miguel de Icaza <miguel@ximian.com>
7655 * expression.cs (Unary::Emit): Remove some dead code.
7656 (Probe): Implement Resolve and Emit for `is'.
7657 (Expression::ConvertImplicitRequired): Attempt to do constant
7658 expression conversions here. Maybe should be moved to
7659 ConvertImplicit, but I am not sure.
7660 (Expression::ImplicitLongConstantConversionPossible,
7661 Expression::ImplicitIntConstantConversionPossible): New functions
7662 that tell whether is it possible to apply an implicit constant
7663 expression conversion.
7665 (ConvertNumericExplicit): Started work on explicit numeric
7668 * cs-parser.jay: Update operator constants.
7670 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
7671 (Parameters::GetSignature): Hook up VerifyArgs here.
7672 (Parameters::VerifyArgs): Verifies that no two arguments have the
7675 * class.cs (Operator): Update the operator names to reflect the
7676 ones that the spec expects (as we are just stringizing the
7679 * expression.cs (Unary::ResolveOperator): Fix bug: Use
7680 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
7681 previous usage did only work for our methods.
7682 (Expression::ConvertImplicit): Handle decimal implicit numeric
7683 conversions as well.
7684 (Expression::InternalTypeConstructor): Used to invoke constructors
7685 on internal types for default promotions.
7687 (Unary::Emit): Implement special handling for the pre/post
7688 increment/decrement for overloaded operators, as they need to have
7689 the same semantics as the other operators.
7691 (Binary::ResolveOperator): ditto.
7692 (Invocation::ConversionExists): ditto.
7693 (UserImplicitCast::Resolve): ditto.
7695 2001-09-26 Ravi Pratap <ravi@ximian.com>
7697 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded
7698 operator, return after emitting body. Regression tests pass again !
7700 * expression.cs (ConvertImplicit): Take TypeContainer as first argument
7701 (Unary::ForceConversion, Binary::ForceConversion): Ditto.
7702 (Invocation::OverloadResolve): Ditto.
7703 (Invocation::BetterFunction, BetterConversion, ConversionExists): Ditto.
7705 * everywhere : update calls to the above methods accordingly.
7707 2001-09-26 Miguel de Icaza <miguel@ximian.com>
7709 * assign.cs (Assign): Make it inherit from ExpressionStatement.
7711 * expression.cs (ExpressionStatement): New base class used for
7712 expressions that can appear in statements, so that we can provide
7713 an alternate path to generate expression that do not leave a value
7716 (Expression::Emit, and all the derivatives): We no longer return
7717 whether a value is left on the stack or not. Every expression
7718 after being emitted leaves a single value on the stack.
7720 * codegen.cs (EmitContext::EmitStatementExpression): Use the
7721 facilties of ExpressionStatement if possible.
7723 * cs-parser.jay: Update statement_expression.

7727 * driver.cs: Change the wording of message
7729 2001-09-25 Ravi Pratap <ravi@ximian.com>
7731 * expression.cs (Binary::ResolveOperator): Had forgottten to set
7732 the type of the expression to the return type of the method if
7733 we have an overloaded operator match ! The regression tests pass again !
7734 (Unary::ResolveOperator): Ditto.
7736 * expression.cs (Invocation::ConversionExists): Correct the member lookup
7737 to find "op_Implicit", not "implicit" ;-)
7738 (UserImplicitCast): New class to take care of user-defined implicit conversions.
7739 (ConvertImplicit, ForceConversion): Take TypeContainer argument
7741 * everywhere : Correct calls to the above accordingly.
7743 * expression.cs (UserImplicitCast::Resolve, ::Emit): Implement.
7744 (ConvertImplicit): Do user-defined conversion if it exists.
7746 2001-09-24 Miguel de Icaza <miguel@ximian.com>
7748 * assign.cs: track location.
7749 (Resolve): Use implicit conversions on assignment.
7751 * literal.cs: Oops. Not good, Emit of short access values should

7814 * typemanager.cs: declare and load enum_type, delegate_type and
7817 * expression.cs (Expression::Emit): Now emit returns a value that

7873 functions, throw exceptions so it is obvious that we are facing a

7878 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
7879 Use a basename for those routines because .NET does not like paths

7896 expression conversions'.
7898 * literal.cs (LongLiteral): Implement long literal class.
7899 (IntLiteral): export the `Value' of the intliteral.
7901 2001-09-19 Ravi Pratap <ravi@ximian.com>

7917 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
7918 operators are found instead of making noise ;-)
7919 (Unary::ResolveOperator): New method to do precisely the same thing which
7920 Binary::ResolveOperator does for Binary expressions.
7921 (Unary.method, .Arguments): Add.
7922 (Unary::OperName): Implement.
7923 (Unary::ForceConversion): Copy and Paste !
7925 * class.cs (Operator::Define): Fix a small bug for the case when we have
7928 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
7929 for the inbuilt operators. Only overloading works for now ;-)
7931 2001-09-18 Miguel de Icaza <miguel@ximian.com>
7933 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
7934 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

7947 (FieldExpr::Emit): Implement.
7949 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
7950 the last instruction contains a return opcode to avoid generating
7951 the last `ret' instruction (this generates correct code, and it is
7952 nice to pass the peverify output).
7954 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
7955 initializer for static and instance variables.
7956 (Constructor::Emit): Allow initializer to be null in the case of
7957 static constructors. Only emit initializer for instance
7960 (TypeContainer::FindMembers): Return a null array if there are no

7970 * driver.cs: Stop compilation if there are parse errors.
7972 * cs-parser.jay (constructor_declaration): Provide default base
7973 initializer for non-static constructors.

7975 initializers if none was specified.
7976 Catch the fact that constructors should not have parameters.
7978 * class.cs: Do not emit parent class initializers for static
7979 constructors, that should be flagged as an error.
7981 2001-09-18 Ravi Pratap <ravi@ximian.com>
7983 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
7984 Move back code into TypeContainer::Populate.

8010 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
8013 (Expression::MemberLookup): Provide a version that allows to
8014 specify the MemberTypes and BindingFlags.
8016 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
8017 so it was not fetching variable information from outer blocks.
8019 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
8020 Beforefieldinit as it was buggy.
8022 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
8025 * class.cs (Constructor::Emit): Only emit if block is not null.
8026 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
8027 deal with this by semantically definining it as if the user had
8030 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
8031 constructors as we now "emit" them at a higher level.

8058 and Unary::Operator.
8060 * cs-parser.jay (operator_declaration, CheckBinaryOperator, CheckUnaryOperator): Update

8069 (TypeContainer::Emit): Emit the operators we have too.
8071 * expression.cs (Binary::Emit): Update to emit the appropriate code for

8078 2001-09-16 Ravi Pratap <ravi@ximian.com>

8106 2001-09-14 Miguel de Icaza <miguel@ximian.com>
8108 * class.cs (TypeContainer::FindMembers): Add support for
8110 (MethodCore): New class that encapsulates both the shared aspects
8111 of a Constructor and a Method.

8115 Load System assembly as well as part of the standard library.
8117 * report.cs: Allow throwing exceptions on errors for debugging.
8119 * modifiers.cs: Do not use `parent', instead use the real type
8120 container to evaluate permission settings.
8122 * class.cs: Put Ravi's patch back in. He is right, and we will
8123 have to cope with the
8125 2001-09-14 Ravi Pratap <ravi@ximian.com>
8127 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
8128 FamORAssem, not FamANDAssem.

8132 * driver.cs: Added --parse option that only parses its input files
8135 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
8136 incorrect. IsTopLevel is not used to tell whether an object is
8137 root_types or not (that can be achieved by testing this ==
8138 root_types). But to see if this is a top-level *class* (not
8139 necessarly our "toplevel" container).
8141 2001-09-14 Ravi Pratap <ravi@ximian.com>
8143 * enum.cs (Enum::Define): Modify to call the Lookup method on the
8144 parent instead of a direct call to GetType.

8148 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
8149 Modifiers.TypeAttr. This should just be a call to that method.
8151 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
8152 object so that we can determine if we are top-level or not.
8154 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
8157 * enum.cs (Enum::Define): Ditto.
8159 * modifiers.cs (FieldAttr): Re-write.
8161 * class.cs (TypeContainer::IsTopLevel): Change accessibility to public.
8162 (TypeContainer::HaveStaticConstructor): New property to provide access
8163 to precisely that info.
8165 * modifiers.cs (MethodAttr): Re-write.
8166 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
8168 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
8169 of top-level types as claimed.
8171 2001-09-13 Miguel de Icaza <miguel@ximian.com>
8173 * expression.cs (MemberLookup): Fruitless attempt to lookup
8174 constructors. Maybe I need to emit default constructors? That
8175 might be it (currently .NET emits this for me automatically).
8176 (Invocation::OverloadResolve): Cope with Arguments == null.
8177 (Invocation::EmitArguments): new function, shared by the new
8179 (Invocation::Emit): Handle static and instance methods. Emit
8180 proper call instruction for virtual or non-virtual invocations.

8191 SimpleLookup): Auxiliary routines to help parse a qualifier
8194 Update qualifier_identifier rule.
8196 * codegen.cs: Removed debugging messages.
8198 * class.cs: Make this a global thing, this acts just as a "key" to
8199 objects that we might have around.
8201 (Populate): Only initialize method_builders_to_methods once.
8203 * expression.cs (PropertyExpr): Initialize type from the
8206 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
8207 Resolve pattern. Attempt to implicitly convert value to boolean.
8210 * expression.cs: Set the type for the int32/int32 argument case.
8211 (Binary::ResolveOperator): Set the return type to boolean for
8212 comparission operators
8214 * typemanager.cs: Remove debugging print code.
8216 (Invocation::Resolve): resolve type.
8218 * class.cs: Allocate a MemberInfo of the correct size, as the code
8219 elsewhere depends on the test to reflect the correct contents.
8221 (Method::) Keep track of parameters, due to System.Reflection holes
8223 (TypeContainer::Populate): Keep track of MethodBuilders to Method
8226 (TypeContainer::FindMembers): Use ArrayList and then copy an array
8227 of the exact size and return that.
8229 (Class::LookupMethodByBuilder): New function that maps
8230 MethodBuilders to its methods. Required to locate the information
8231 on methods because System.Reflection bit us again.
8233 * support.cs: New file, contains an interface ParameterData and
8234 two implementations: ReflectionParameters and InternalParameters
8235 used to access Parameter information. We will need to grow this
8238 * expression.cs (Invocation::GetParameterData): implement a cache
8239 and a wrapper around the ParameterData creation for methods.
8240 (Invocation::OverloadResolve): Use new code.
8242 2001-09-13 Ravi Pratap <ravi@ximian.com>
8244 * class.cs (TypeContainer::EmitField): Remove and move into
8245 (Field::Define): here and modify accordingly.
8246 (Field.FieldBuilder): New member.
8247 (TypeContainer::Populate): Update accordingly.
8248 (TypeContainer::FindMembers): Implement.
8250 2001-09-13 Miguel de Icaza <miguel@ximian.com>
8252 * statement.cs: (VariableInfo::VariableType): New field to be
8253 initialized with the full type once it is resolved.
8255 2001-09-12 Miguel de Icaza <miguel@ximian.com>
8257 * parameter.cs (GetParameterInfo): Use a type cache to compute
8258 things only once, and to reuse this information

8261 (OpcodeCast::Emit): fix.
8263 (ParameterReference::Resolve): Implement.
8264 (ParameterReference::Emit): Implement.
8266 * cs-parser.jay: Fix bug introduced by Ravi, variable initializers

8296 2001-09-12 Ravi Pratap <ravi@ximian.com>
8298 * class.cs (TypeContainer::FindMembers): Method which does exactly
8299 what Type.FindMembers does, only we don't have to use reflection. No
8302 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
8303 typecontainer objects as we need to get at them.
8304 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.
8306 * rootcontext.cs : Correspondingly modify called to AddUserType to pass the
8307 typecontainer object.
8309 * expression.cs (MemberLookup): Modify signature to take a RootContext object instead
8310 of just a Report object.
8312 2001-09-11 Ravi Pratap <ravi@ximian.com>

8328 (Operator::Define): Re-write logic to get types by using the LookupType method

8331 (Event::Define): Ditto.
8332 (Property::Define): Ditto.
8334 2001-09-10 Ravi Pratap <ravi@ximian.com>
8336 * class.cs (TypeContainer::Populate): Now define operators too.
8337 (TypeContainer.Operators): New property to access the list of operators
8339 (Operator.OperatorMethodBuilder): New member to hold the method builder
8340 for the operator we are defining.
8341 (Operator::Define): Implement.
8343 2001-09-10 Ravi Pratap <ravi@ximian.com>
8345 * class.cs (Event::Define): Make the prefixes of the accessor methods
8346 addOn_ and removeOn_
8348 * genericparser.cs (GenericParser::error): Overloaded method to handle the case
8349 of the location being passed in too. Ideally, this should go later since all
8350 error reporting should be done through the Report object.
8352 * class.cs (TypeContainer.Indexers): New property to access the list of indexers.
8353 (Populate): Iterate thru the indexers we have and define them too.

8361 my previous implementation, did not work.
8363 * typemanager.cs: Add a couple of missing types (the longs).
8365 * literal.cs: Use TypeManager.bool_type instead of getting it.
8367 * expression.cs (EventExpr): New kind of expressions.
8368 (Expressio::ExprClassFromMemberInfo): finish
8370 2001-09-08 Miguel de Icaza <miguel@ximian.com>

8374 2001-09-08 Ravi Pratap <ravi@ximian.com>
8376 * Merge in changes and adjust code to tackle conflicts. Backed out my

8395 (CheckBinaryOperator): Same here.
8397 * rootcontext.cs (LookupType): Add an extra lookup which simply does a lookup
8398 on the name without any prefixes of namespace names etc. This is because we
8399 already might have something already fully qualified like
8400 'System.Console.WriteLine'

8404 2001-09-07 Ravi Pratap <ravi@ximian.com>

8727 and re-write the code in the actions to extract the specific and
8728 general catch clauses by being a little smart ;-)
8730 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !

8740 (catch_clauses): Fixed gross error which made Key and Value of the
8741 DictionaryEntry the same : $1 !!
8743 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
8745 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'

8754 (indexer_declarator): Implement actions.
8755 (parsing_indexer): New local boolean used to keep track of whether

8783 concatenating all the commas together, just as they appear.
8784 (opt_dim_separators): Modify accordingly

8789 instead of ignoring the rank_specifiers.
8790 (expression_list): Implement to collect the expressions

8817 types after we have populated the type manager with the user
8818 defined types (this distinction will be important later while
8819 compiling corlib.dll)
8821 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
8822 on Expression Classification. Now all expressions have a method
8823 `Resolve' and a method `Emit'.
8825 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
8826 generation from working. Also add some temporary debugging
8829 2001-08-24 Miguel de Icaza <miguel@ximian.com>
8831 * codegen.cs: Lots of code generation pieces. This is only the
8832 beginning, will continue tomorrow with more touches of polish. We

8840 emission to keep a context. Most of the code generation will be

8863 move from Properties to public readonly fields.
8864 (Method::ParameterTypes): Returns the parameter types for the
8865 function, and implements a cache that will be useful later when I
8866 do error checking and the semantic analysis on the methods is
8868 (Constructor::GetCallingConvention): Renamed from CallingConvetion
8869 and made a method, optional argument tells whether this is a class
8870 or a structure to apply the `has-this' bit.

8873 (Method::Define): Defines the type, a second pass is performed
8874 later to populate the methods.

8903 (Field::) use readonly public fields instead of properties also.
8905 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
8906 track of static constructors; If none is used, turn on
8907 BeforeFieldInit in the TypeAttributes.
8909 * cs-parser.jay (opt_argument_list): now the return can be null
8910 for the cases where there are no arguments.
8912 (constructor_declarator): If there is no implicit `base' or

8915 * modifiers.cs (MethodAttr): New static function maps a set of
8916 modifiers flags into a MethodAttributes enum
8917 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
8918 MethodAttr, TypeAttr to represent the various mappings where the
8920 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
8922 2001-08-19 Miguel de Icaza <miguel@ximian.com>

8939 `public readonly' fields.
8941 2001-08-16 Miguel de Icaza <miguel@ximian.com>
8943 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
8944 initialize their hashtables/arraylists only when they are needed
8945 instead of doing this always.
8947 * parameter.cs: Handle refs and out parameters.
8949 * cs-parser.jay: Use an ArrayList to construct the arguments
8950 instead of the ParameterCollection, and then cast that to a
8953 * parameter.cs: Drop the use of ParameterCollection and use
8954 instead arrays of Parameters.
8956 (GetParameterInfo): Use the Type, not the Name when resolving
8959 2001-08-13 Miguel de Icaza <miguel@ximian.com>

8976 this System.Reflection code is. Kudos to Microsoft
8978 * typemanager.cs: Implement a type cache and avoid loading all
8979 types at boot time. Wrap in LookupType the internals. This made
8980 the compiler so much faster. Wow. I rule!
8982 * driver.cs: Make sure we always load mscorlib first (for
8983 debugging purposes, nothing really important).
8985 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
8986 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
8988 * rootcontext.cs: Lookup types on their namespace; Lookup types
8989 on namespaces that have been imported using the `using' keyword.
8991 * class.cs (TypeContainer::TypeAttr): Virtualize.
8992 (Class::TypeAttr): Return attributes suitable for this bad boy.
8993 (Struct::TypeAttr): ditto.

9021 (GetInterfaces): simplified.
9022 (ResolveTree): Encapsulated all the tree resolution here.
9023 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
9026 * driver.cs: Add support for --nostdlib, to avoid loading the
9028 (Main): Do not put tree resolution here.
9030 * rootcontext.cs: Beginning of the class resolution.
9032 2001-08-03 Miguel de Icaza <miguel@ximian.com>
9034 * rootcontext.cs: Provide better error reporting.
9036 * cs-parser.jay (interface_base): set our $$ to be interfaces.
9038 * rootcontext.cs (CreateInterface): Handle the case where there
9039 are no parent interfaces.
9041 (CloseTypes): Routine to flush types at the end.
9042 (CreateInterface): Track types.
9043 (GetInterfaces): Returns an array of Types from the list of
9046 * typemanager.c (AddUserType): Mechanism to track user types (puts
9047 the type on the global type hash, and allows us to close it at the
9050 2001-08-02 Miguel de Icaza <miguel@ximian.com>
9052 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
9053 RecordInterface instead.
9055 * cs-parser.jay: Updated to reflect changes above.
9057 * decl.cs (Definition): Keep track of the TypeBuilder type that
9058 represents this type here. Not sure we will use it in the long
9059 run, but wont hurt for now.
9061 * driver.cs: Smaller changes to accomodate the new code.
9063 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
9066 * rootcontext.cs (CreateInterface): New method, used to create
9067 the System.TypeBuilder type for interfaces.
9068 (ResolveInterfaces): new entry point to resolve the interface
9070 (CodeGen): Property, used to keep track of the code generator.
9072 2001-07-26 Miguel de Icaza <miguel@ximian.com>
9074 * cs-parser.jay: Add a second production for delegate_declaration
9077 (enum_body): Put an opt_comma here instead of putting it on
9078 enum_body or enum_member_declarations so we can handle trailing
9079 commas on enumeration members. Gets rid of a shift/reduce.
9081 (type_list): Need a COMMA in the middle.
9083 (indexer_declaration): Tell tokenizer to recognize get/set
9085 * Remove old targets.
9087 * Re-add the parser target.
9089 2001-07-13 Simon Cozens <simon@simon-cozens.org>
9091 * cs-parser.jay: Add precendence rules for a number of operators
9092 ot reduce the number of shift/reduce conflicts in the grammar.
9094 2001-07-17 Miguel de Icaza <miguel@ximian.com>
9096 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
9099 Get rid of old crufty code.
9101 * rootcontext.cs: Use this to keep track of the parsed
9102 representation and the defined types available to the program.
9104 * gen-treedump.cs: adjust for new convention.
9106 * type.cs: Split out the type manager, and the assembly builder
9109 * typemanager.cs: the type manager will live here now.
9111 * cil-codegen.cs: And the code generator here.
9113 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
9115 * makefile: Fixed up for easy making.
9117 2001-07-13 Simon Cozens <simon@simon-cozens.org>
9119 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
9122 (unary_expression): Expand pre_increment_expression and
9123 post_decrement_expression to reduce a shift/reduce.
9125 2001-07-11 Simon Cozens
9127 * cs-tokenizer.cs: Hex numbers should begin with a 0.
9129 Improve allow_keyword_as_indent name.
9131 2001-06-19 Miguel de Icaza <miguel@ximian.com>
9133 * Adjustments for Beta2.
9135 2001-06-13 Miguel de Icaza <miguel@ximian.com>
9137 * decl.cs: Added `Define' abstract method.
9138 (InTransit): new property, used to catch recursive definitions.
9140 * interface.cs: Implement `Define'.
9142 * modifiers.cs: Map Modifiers.constants to
9143 System.Reflection.TypeAttribute flags.
9145 * class.cs: Keep track of types and user-defined types.
9146 (BuilderInit): New method for creating an assembly
9147 (ResolveType): New function to launch the resolution process, only
9148 used by interfaces for now.
9150 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
9151 that are inserted into the name space.
9153 2001-06-08 Miguel de Icaza <miguel@ximian.com>
9155 * ARGH. I have screwed up my tree so many times due to the use of
9156 rsync rather than using CVS. Going to fix this at once.
9158 * driver.cs: Objetify driver. Load assemblies, use assemblies to
9161 2001-06-07 Miguel de Icaza <miguel@ximian.com>
9163 * Experiment successful: Use System.Type rather that our own
9166 2001-05-25 Miguel de Icaza <miguel@ximian.com>
9168 * cs-parser.jay: Removed nsAliases from here.
9170 Use new namespaces, handle `using XXX;'
9172 * namespace.cs: Reimplemented namespace handling, use a recursive
9173 definition of the class. Now we can keep track of using clauses
9174 and catch invalid using clauses.
9176 2001-05-24 Miguel de Icaza <miguel@ximian.com>
9178 * gen-treedump.cs: Adapted for all the renaming.
9180 * expression.cs (Expression): this class now has a Type property
9181 which returns an expression Type.
9183 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
9184 `Type', as this has a different meaning now in the base
9186 2001-05-22 Miguel de Icaza <miguel@ximian.com>
9188 * interface.cs, class.cs: Removed from all the sources the
9189 references to signature computation, as we can not do method
9190 signature computation during the parsing time, as we are not
9191 trying to solve at that point distinguishing:
9195 void a (NS.Blah x) {}
9198 Which depending on the context might be valid or not, as we do not
9199 know if Blah is the same thing as NS.Blah at that point.
9201 * Redid everything so the code uses TypeRefs now instead of
9202 Types. TypeRefs are just temporary type placeholders, that need
9203 to be resolved. They initially have a pointer to a string and the
9204 current scope in which they are used. This is used later by the
9205 compiler to resolve the reference to an actual Type.
9207 * DeclSpace is no longer a CIR.Type, and neither are
9208 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
9209 are all DeclSpaces, but no Types.
9211 * type.cs (TypeRefManager): This implements the TypeRef manager,
9212 which keeps track of all the types that need to be resolved after
9213 the parsing has finished.
9215 2001-05-13 Miguel de Icaza <miguel@ximian.com>
9217 * ARGH. We are going to have to store `foreach' as a class rather
9218 than resolving it, as we need to verify error 1579 after name
9219 resolution. *OR* we could keep a flag that says `This request to
9220 IEnumerator comes from a foreach statement' which we can then use
9221 to generate the error.
9223 2001-05-10 Miguel de Icaza <miguel@ximian.com>
9225 * class.cs (TypeContainer.AddMethod): we now add methods to the
9226 MethodGroup instead of the method hashtable.
9228 * expression.cs: Add MethodGroup abstraction, which gets us one
9229 step closer to the specification in the way we handle method
9232 * cs-parser.jay (primary_expression): qualified_identifier now
9233 tried to match up an identifier to a local variable reference or
9234 to a parameter reference.
9236 current_local_parameters is now a parser global variable that
9237 points to the current parameters for the block, used during name
9240 (property_declaration): Now creates an implicit `value' argument to
9243 2001-05-09 Miguel de Icaza <miguel@ximian.com>
9245 * parameter.cs: Do not use `param' arguments as part of the
9246 signature, per the spec.
9248 2001-05-08 Miguel de Icaza <miguel@ximian.com>
9250 * decl.cs: Base class for classes, structs and interfaces. This
9251 is the "Declaration Space"
9253 * cs-parser.jay: Use CheckDef for checking declaration errors
9254 instead of having one on each function.
9256 * class.cs: Factor out some code for handling error handling in
9257 accordance to the "Declarations" section in the "Basic Concepts"
9258 chapter in the ECMA C# spec.
9260 * interface.cs: Make all interface member classes derive from
9261 InterfaceMemberBase.
9263 2001-05-07 Miguel de Icaza <miguel@ximian.com>
9265 * Many things: all interfaces are parsed and generated in
9266 gen-treedump. Support for member variables, constructors,
9267 destructors, properties, constants is there.
9269 Beginning of the IL backend, but very little done, just there for
9272 2001-04-29 Miguel de Icaza <miguel@ximian.com>
9274 * cs-parser.jay: Fix labeled statement.
9276 * cs-tokenizer.cs (escape): Escape " and ' always.
9277 ref_line, ref_name: keep track of the line/filename as instructed
9278 by #line by the compiler.
9281 2001-04-27 Miguel de Icaza <miguel@ximian.com>
9283 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
9284 to match the values in System.CodeDOM.
9286 Divid renamed to Divide.
9288 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
9290 (Statements.set): remove.
9292 * System.CodeDOM/CodeCatchClause.cs: always have a valid
9295 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
9296 falseStatements always have valid values.
9298 * cs-parser.jay: Use System.CodeDOM now.
