1 2002-09-11 Miguel de Icaza <miguel@ximian.com>
3 * pending.cs (PendingImplementation): pass the container pointer.
5 * interface.cs (GetMethods): Allow for recursive definition. Long
6 term, I would like to move every type to support recursive
7 definitions, not the current ordering mechanism that we have right
10 The situation is this: Attributes are handled before interfaces,
11 so we can apply attributes to interfaces. But some attributes
12 implement interfaces, we will now handle the simple cases
13 (recursive definitions will just get an error).
15 * parameter.cs: Only invalidate types at the end if we fail to
18 2002-09-09 Martin Baulig <martin@gnome.org>
20 * ecore.cs (PropertyExpr.Emit): Also check for
21 TypeManager.system_int_array_get_length so this'll also work when
22 compiling corlib. Fixes #30003.
24 2002-09-09 Martin Baulig <martin@gnome.org>
26 * expression.cs (ArrayCreation.MakeByteBlob): Added support for enums
27 and throw an exception if we can't get the type's size. Fixed #30040,
30 2002-09-09 Martin Baulig <martin@gnome.org>
32 * ecore.cs (PropertyExpr.DoResolve): Added check for static properies.
34 * expression.cs (SizeOf.DoResolve): Sizeof is only allowed in unsafe
35 context. Fixes bug #30027.
37 * delegate.cs (NewDelegate.Emit): Use OpCodes.Ldvirtftn for
38 virtual functions. Fixes bug #30043, added test-164.cs.
40 2002-09-08 Ravi Pratap <ravi@ximian.com>
42 * attribute.cs : Fix a small NullRef crash thanks to my stupidity.
44 2002-09-08 Nick Drochak <ndrochak@gol.com>
46 * driver.cs: Use an object to get the windows codepage since it's not a
49 2002-09-08 Miguel de Icaza <miguel@ximian.com>
51 * statement.cs (For.Emit): for infinite loops (test == null)
52 return whether there is a break inside, not always "true".
54 * namespace.cs (UsingEntry): New struct to hold the name of the
55 using definition, the location where it is defined, and whether it
56 has been used in a successful type lookup.
58 * rootcontext.cs (NamespaceLookup): Use UsingEntries instead of
63 2002-09-06 Ravi Pratap <ravi@ximian.com>
65 * attribute.cs : Fix incorrect code which relied on catching
66 a NullReferenceException to detect a null being passed in
67 where an object was expected.
69 2002-09-06 Miguel de Icaza <miguel@ximian.com>
71 * statement.cs (Try): flag the catch variable as assigned
73 * expression.cs (Cast): Simplified by using ResolveType instead of
76 * statement.cs (Catch): Fix bug by using ResolveType.
78 2002-09-06 Ravi Pratap <ravi@ximian.com>
80 * expression.cs (BetterConversion): Special case for when we have
81 a NullLiteral as the argument and we have to choose between string
82 and object types - we choose string the way csc does.
84 * attribute.cs (Attribute.Resolve): Catch the
85 NullReferenceException and report error #182 since the Mono
86 runtime no more has the bug and having this exception raised means
87 we tried to select a constructor which takes an object and is
90 2002-09-05 Ravi Pratap <ravi@ximian.com>
92 * expression.cs (Invocation.OverloadResolve): Flag a nicer error
93 message (1502, 1503) when we can't locate a method after overload
94 resolution. This is much more informative and closes the bug
97 * interface.cs (PopulateMethod): Return if there are no argument
98 types. Fixes a NullReferenceException bug.
100 * attribute.cs (Attribute.Resolve): Ensure we allow TypeOf
101 expressions too. Previously we were checking only in one place for
102 positional arguments leaving out named arguments.
104 * ecore.cs (ImplicitNumericConversion): Conversion from underlying
105 type to the enum type is not allowed. Remove code corresponding to
108 (ConvertNumericExplicit): Allow explicit conversions from
109 the underlying type to enum type. This precisely follows the spec
110 and closes a bug filed by Gonzalo.
112 2002-09-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
115 * compiler.csproj.user: patch from Adam Chester (achester@bigpond.com).
117 2002-09-03 Miguel de Icaza <miguel@ximian.com>
119 * statement.cs (SwitchLabel.ResolveAndReduce): In the string case,
120 it was important that we stored the right value after the
121 reduction in `converted'.
123 2002-09-04 Martin Baulig <martin@gnome.org>
125 * location.cs (Location.SymbolDocument): Use full pathnames for the
128 2002-08-30 Miguel de Icaza <miguel@ximian.com>
130 * expression.cs (ComposedCast): Use DeclSparce.ResolveType instead
131 of the expression resolve mechanism, because that will catch the
132 SimpleName error failures.
134 (Conditional): If we can not resolve the
135 expression, return, do not crash.
137 2002-08-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
140 (location): display token name instead of its number.
142 2002-08-28 Martin Baulig <martin@gnome.org>
144 * expression.cs (Binary.ResolveOperator): Don't silently return
145 but return an error if an operator cannot be applied between two
148 2002-08-28 Martin Baulig <martin@gnome.org>
150 * class.cs (Constructor.Define): Set the permission attributes
151 correctly instead of making all constructors public.
153 2002-08-28 Martin Baulig <martin@gnome.org>
155 * ecore.cs (Expression.DoResolve): Do a TypeManager.MemberLook
156 for private members before reporting a CS0103; if we find anything,
159 2002-08-28 Martin Baulig <martin@gnome.org>
161 * typemanager.cs (TypeManager.FilterWithClosure): It's not enough
162 to check whether `closure_start_type == closure_invocation_type',
163 we also need to check whether `m.DeclaringType == closure_invocation_type'
164 before bypassing the permission checks. We might be accessing
165 protected/private members from the base class.
166 (TypeManager.RealMemberLookup): Only set private_ok if private
167 members were requested via BindingFlags.NonPublic.
169 * ecore.cs (MethodGroupExpr.IsExplicitImpl): New property.
171 * expression.cs (MemberAccess.ResolveMemberAccess): Set
172 MethodGroupExpr.IsExplicitImpl if appropriate.
173 (Invocation.DoResolve): Don't report the CS0120 for explicit
174 interface implementations.
176 2002-08-27 Martin Baulig <martin@gnome.org>
178 * expression.cs (Invocation.DoResolve): If this is a static
179 method and we don't have an InstanceExpression, we must report
182 2002-08-25 Martin Baulig <martin@gnome.org>
184 * expression.cs (Binary.ResolveOperator): Don't allow `!=' and
185 `==' between a valuetype and an object.
187 2002-08-25 Miguel de Icaza <miguel@ximian.com>
189 * ecore.cs (TypeExpr): Provide a ToString method.
191 2002-08-24 Martin Baulig <martin@gnome.org>
193 * codegen.cs (CodeGen.InitMonoSymbolWriter): The symbol file is
194 now called proggie.dbg and it's a binary file.
196 2002-08-23 Martin Baulig <martin@gnome.org>
198 * decl.cs (MemberCache.AddMethods): Ignore varargs methods.
200 2002-08-23 Martin Baulig <martin@gnome.org>
202 * struct.cs (MyStructInfo.ctor): Make this work with empty
203 structs; it's not allowed to use foreach() on null.
205 2002-08-23 Martin Baulig <martin@gnome.org>
207 * codegen.cs (CodeGen.InitMonoSymbolWriter): Tell the symbol
208 writer the full pathname of the generated assembly.
210 2002-08-23 Martin Baulig <martin@gnome.org>
212 * statements.cs (FlowBranching.UsageVector.MergeChildren):
213 A `finally' block never returns or breaks; improved handling of
216 2002-08-23 Martin Baulig <martin@gnome.org>
218 * statement.cs (Throw.Resolve): Allow `throw null'.
220 2002-08-23 Martin Baulig <martin@gnome.org>
222 * expression.cs (MemberAccess.ResolveMemberAccess): If this is an
223 EventExpr, don't do a DeclaredOnly MemberLookup, but check whether
224 `ee.EventInfo.DeclaringType == ec.ContainerType'. The
225 MemberLookup would return a wrong event if this is an explicit
226 interface implementation and the class has an event with the same
229 2002-08-23 Martin Baulig <martin@gnome.org>
231 * statement.cs (Block.AddChildVariableNames): New public method.
232 (Block.AddChildVariableName): Likewise.
233 (Block.IsVariableNameUsedInChildBlock): Likewise.
234 (Block.AddVariable): Check whether a variable name has already
235 been used in a child block.
237 * cs-parser.jay (declare_local_variables): Mark all variable names
238 from the current block as being used in a child block in the
241 2002-08-23 Martin Baulig <martin@gnome.org>
243 * codegen.cs (CodeGen.InitializeSymbolWriter): Abort if we can't
244 find the symbol writer.
246 * driver.cs: csc also allows the arguments to /define being
247 separated by commas, not only by semicolons.
249 2002-08-23 Martin Baulig <martin@gnome.org>
251 * interface.cs (Interface.GetMembers): Added static check for events.
253 2002-08-15 Martin Baulig <martin@gnome.org>
255 * class.cs (MethodData.EmitDestructor): In the Expression.MemberLookup
256 call, use ec.ContainerType.BaseType as queried_type and invocation_type.
258 * ecore.cs (Expression.MemberLookup): Added documentation and explained
259 why the MethodData.EmitDestructor() change was necessary.
261 2002-08-20 Martin Baulig <martin@gnome.org>
263 * class.cs (TypeContainer.FindMembers): Added static check for events.
265 * decl.cs (MemberCache.AddMembers): Handle events like normal members.
267 * typemanager.cs (TypeHandle.GetMembers): When queried for events only,
268 use Type.GetEvents(), not Type.FindMembers().
270 2002-08-20 Martin Baulig <martin@gnome.org>
272 * decl.cs (MemberCache): Added a special method cache which will
273 be used for method-only searched. This ensures that a method
274 search will return a MethodInfo with the correct ReflectedType for
277 2002-08-20 Martin Baulig <martin@gnome.org>
279 * decl.cs (DeclSpace.FindMembers): Made this public.
281 2002-08-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
283 * delegate.cs: fixed build on windows.
284 [FIXME: Filed as bug #29150: MCS must report these errors.]
286 2002-08-19 Ravi Pratap <ravi@ximian.com>
288 * ecore.cs (StandardConversionExists): Return a false
289 if we are trying to convert the void type to anything else
290 since that is not allowed.
292 * delegate.cs (DelegateInvocation.DoResolve): Ensure that
293 we flag error 70 in the event an event is trying to be accessed
294 directly from outside the declaring type.
296 2002-08-20 Martin Baulig <martin@gnome.org>
298 * typemanager.cs, decl.cs: Moved MemberList, IMemberContainer and
299 MemberCache from typemanager.cs to decl.cs.
301 2002-08-19 Martin Baulig <martin@gnome.org>
303 * class.cs (TypeContainer): Implement IMemberContainer.
304 (TypeContainer.DefineMembers): Create the MemberCache.
305 (TypeContainer.FindMembers): Do better BindingFlags checking; only
306 return public members if BindingFlags.Public was given, check
307 whether members are static.
309 2002-08-16 Martin Baulig <martin@gnome.org>
311 * decl.cs (DeclSpace.Define): Splitted this in Define and
312 DefineMembers. DefineMembers is called first and initializes the
315 * rootcontext.cs (RootContext.DefineMembers): New function. Calls
316 DefineMembers() on all our DeclSpaces.
318 * class.cs (TypeContainer.Define): Moved all code to DefineMembers(),
319 but call DefineMembers() on all nested interfaces. We call their
320 Define() in our new Define() function.
322 * interface.cs (Interface): Implement IMemberContainer.
323 (Interface.Define): Moved all code except the attribute stuf to
325 (Interface.DefineMembers): Initialize the member cache.
327 * typemanager.cs (IMemberFinder): Removed this interface, we don't
328 need this anymore since we can use MemberCache.FindMembers directly.
330 2002-08-19 Martin Baulig <martin@gnome.org>
332 * typemanager.cs (MemberCache): When creating the cache for an
333 interface type, add all inherited members.
334 (TypeManager.MemberLookup_FindMembers): Changed `ref bool searching'
335 to `out bool used_cache' and documented it.
336 (TypeManager.MemberLookup): If we already used the cache in the first
337 iteration, we don't need to do the interfaces check.
339 2002-08-19 Martin Baulig <martin@gnome.org>
341 * decl.cs (DeclSpace.FindMembers): New abstract method. Moved this
342 here from IMemberFinder and don't implement this interface anymore.
343 (DeclSpace.MemberCache): Moved here from IMemberFinder.
345 * typemanager.cs (IMemberFinder): This interface is now only used by
346 classes which actually support the member cache.
347 (TypeManager.builder_to_member_finder): Renamed to builder_to_declspace
348 since we only put DeclSpaces into this Hashtable.
349 (MemberLookup_FindMembers): Use `builder_to_declspace' if the type is
350 a dynamic type and TypeHandle.GetTypeHandle() otherwise.
352 2002-08-16 Martin Baulig <martin@gnome.org>
354 * typemanager.cs (ICachingMemberFinder): Removed.
355 (IMemberFinder.MemberCache): New property.
356 (TypeManager.FindMembers): Merged this with RealFindMembers().
357 This function will never be called from TypeManager.MemberLookup()
358 so we can't use the cache here, just the IMemberFinder.
359 (TypeManager.MemberLookup_FindMembers): Check whether the
360 IMemberFinder has a MemberCache and call the cache's FindMembers
362 (MemberCache): Rewrote larger parts of this yet another time and
365 2002-08-15 Miguel de Icaza <miguel@ximian.com>
367 * driver.cs (LoadArgs): Support quoting.
369 (Usage): Show the CSC-like command line arguments.
371 Improved a few error messages.
373 2002-08-15 Martin Baulig <martin@gnome.org>
375 * typemanager.cs (IMemberContainer.Type): New property.
376 (IMemberContainer.IsInterface): New property.
378 The following changes are conditional to BROKEN_RUNTIME, which is
379 defined at the top of the file.
381 * typemanager.cs (MemberCache.MemberCache): Don't add the base
382 class'es members, but add all members from TypeHandle.ObjectType
383 if we're an interface.
384 (MemberCache.AddMembers): Set the Declared flag if member.DeclaringType
386 (MemberCache.CacheEntry.Container): Removed this field.
387 (TypeHandle.GetMembers): Include inherited members.
389 2002-08-14 Gonzalo Paniagua Javier <gonzalo@ximian.com>
391 * typemanager.cs: fixed compilation and added a comment on a field that
394 2002-08-15 Martin Baulig <martin@gnome.org>
396 * class.cs (ConstructorInitializer.Resolve): In the
397 Expression.MemberLookup call, use the queried_type as
400 * typemanager.cs (IMemberContainer.GetMembers): Removed the `bool
401 declared' attribute, it's always true.
402 (IMemberContainer.Parent, IMemberContainer.Name): New properties.
403 (TypeManager.MemberLookup_FindMembers): [FIXME FIXME FIXME] Added
404 temporary wrapper for FindMembers which tells MemberLookup whether
405 members from the base classes are included in the return value.
406 This will go away soon.
407 (TypeManager.MemberLookup): Use this temporary hack here; once the
408 new MemberCache is completed, we don't need to do the DeclaredOnly
409 looping here anymore since the MemberCache will take care of this.
410 (TypeManager.IsSubclassOrNestedChildOf): Allow `type == parent'.
411 (MemberCache): When creating the MemberCache for a class, get
412 members from the current class and all its base classes.
413 (MemberCache.CacheEntry.Container): New field. This is a
414 temporary hack until the Mono runtime is fixed to distinguish
415 between ReflectedType and DeclaringType. It allows us to use MCS
416 with both the MS runtime and the unfixed Mono runtime without
417 problems and without accecting performance.
418 (MemberCache.SearchMembers): The DeclaredOnly looping from
419 TypeManager.MemberLookup is now done here.
421 2002-08-14 Martin Baulig <martin@gnome.org>
423 * statement.cs (MyStructInfo.MyStructInfo): Don't call
424 Type.GetFields on dynamic types but get the fields from the
425 corresponding TypeContainer.
426 (MyStructInfo.GetStructInfo): Added check for enum types.
428 * typemanager.cs (MemberList.IsSynchronized): Implemented.
429 (MemberList.SyncRoot): Implemented.
430 (TypeManager.FilterWithClosure): No need to check permissions if
431 closure_start_type == closure_invocation_type, don't crash if
432 closure_invocation_type is null.
434 2002-08-13 Martin Baulig <martin@gnome.org>
436 Rewrote TypeContainer.FindMembers to use a member cache. This
437 gives us a speed increase of about 35% for the self-hosting MCS
438 build and of about 15-20% for the class libs (both on GNU/Linux).
440 * report.cs (Timer): New class to get enhanced profiling. This
441 whole class is "TIMER" conditional since it remarkably slows down
444 * class.cs (MemberList): New class. This is an IList wrapper
445 which we're now using instead of passing MemberInfo[]'s around to
446 avoid copying this array unnecessarily.
447 (IMemberFinder.FindMember): Return a MemberList, not a MemberInfo [].
448 (ICachingMemberFinder, IMemberContainer): New interface.
449 (TypeManager.FilterWithClosure): If `criteria' is null, the name
450 has already been checked, otherwise use it for the name comparision.
451 (TypeManager.FindMembers): Renamed to RealMemberFinder and
452 provided wrapper which tries to use ICachingMemberFinder.FindMembers
453 if possible. Returns a MemberList, not a MemberInfo [].
454 (TypeHandle): New class, implements IMemberContainer. We create
455 one instance of this class per type, it contains a MemberCache
456 which is used to do the member lookups.
457 (MemberCache): New class. Each instance of this class contains
458 all members of a type and a name-based hash table.
459 (MemberCache.FindMembers): This is our new member lookup
460 function. First, it looks up all members of the requested name in
461 the hash table. Then, it walks this list and sorts out all
462 applicable members and returns them.
464 2002-08-13 Martin Baulig <martin@gnome.org>
466 In addition to a nice code cleanup, this gives us a performance
467 increase of about 1.4% on GNU/Linux - not much, but it's already
468 half a second for the self-hosting MCS compilation.
470 * typemanager.cs (IMemberFinder): New interface. It is used by
471 TypeManager.FindMembers to call FindMembers on a TypeContainer,
472 Enum, Delegate or Interface.
473 (TypeManager.finder_to_member_finder): New PtrHashtable.
474 (TypeManager.finder_to_container): Removed.
475 (TypeManager.finder_to_delegate): Removed.
476 (TypeManager.finder_to_interface): Removed.
477 (TypeManager.finder_to_enum): Removed.
479 * interface.cs (Interface): Implement IMemberFinder.
481 * delegate.cs (Delegate): Implement IMemberFinder.
483 * enum.cs (Enum): Implement IMemberFinder.
485 * class.cs (TypeContainer): Implement IMemberFinder.
487 2002-08-12 Martin Baulig <martin@gnome.org>
489 * ecore.cs (TypeExpr.DoResolveType): Mark this as virtual.
491 2002-08-12 Martin Baulig <martin@gnome.org>
493 * ecore.cs (ITypeExpression): New interface for expressions which
495 (TypeExpression): Renamed to TypeLookupExpression.
496 (Expression.DoResolve): If we're doing a types-only lookup, the
497 expression must implement the ITypeExpression interface and we
498 call DoResolveType() on it.
499 (SimpleName): Implement the new ITypeExpression interface.
500 (SimpleName.SimpleNameResolve): Removed the ec.OnlyLookupTypes
501 hack, the situation that we're only looking up types can't happen
502 anymore when this method is called. Moved the type lookup code to
503 DoResolveType() and call it.
504 (SimpleName.DoResolveType): This ITypeExpression interface method
505 is now doing the types-only lookup.
506 (TypeExpr, TypeLookupExpression): Implement ITypeExpression.
507 (ResolveFlags): Added MaskExprClass.
509 * expression.cs (MemberAccess): Implement the ITypeExpression
511 (MemberAccess.DoResolve): Added support for a types-only lookup
512 when we're called via ITypeExpression.DoResolveType().
513 (ComposedCast): Implement the ITypeExpression interface.
515 * codegen.cs (EmitContext.OnlyLookupTypes): Removed. Call
516 Expression.Resolve() with ResolveFlags.Type instead.
518 2002-08-12 Martin Baulig <martin@gnome.org>
520 * interface.cs (Interface.Define): Apply attributes.
522 * attribute.cs (Attribute.ApplyAttributes): Added support for
523 interface attributes.
525 2002-08-11 Martin Baulig <martin@gnome.org>
527 * statement.cs (Block.Emit): Only check the "this" variable if we
528 do not always throw an exception.
530 * ecore.cs (PropertyExpr.DoResolveLValue): Implemented, check
531 whether the property has a set accessor.
533 2002-08-11 Martin Baulig <martin@gnome.org>
535 Added control flow analysis support for structs.
537 * ecore.cs (ResolveFlags): Added `DisableFlowAnalysis' to resolve
538 with control flow analysis turned off.
539 (IVariable): New interface.
540 (SimpleName.SimpleNameResolve): If MemberAccess.ResolveMemberAccess
541 returns an IMemberExpr, call DoResolve/DoResolveLValue on it.
542 (FieldExpr.DoResolve): Resolve the instance expression with flow
543 analysis turned off and do the definite assignment check after the
544 resolving when we know what the expression will resolve to.
546 * expression.cs (LocalVariableReference, ParameterReference):
547 Implement the new IVariable interface, only call the flow analysis
548 code if ec.DoFlowAnalysis is true.
549 (This): Added constructor which takes a Block argument. Implement
550 the new IVariable interface.
551 (MemberAccess.DoResolve, MemberAccess.DoResolveLValue): Call
552 DoResolve/DoResolveLValue on the result of ResolveMemberLookup().
553 This does the definite assignment checks for struct members.
555 * class.cs (Constructor.Emit): If this is a non-static `struct'
556 constructor which doesn't have any initializer, call
557 Block.AddThisVariable() to tell the flow analysis code that all
558 struct elements must be initialized before control returns from
561 * statement.cs (MyStructInfo): New public class.
562 (UsageVector.this [VariableInfo vi]): Added `int field_idx'
563 argument to this indexer. If non-zero, check an individual struct
564 member, not the whole struct.
565 (FlowBranching.CheckOutParameters): Check struct members.
566 (FlowBranching.IsVariableAssigned, SetVariableAssigned): Added
567 overloaded versions of these methods which take an additional
568 `int field_idx' argument to check struct members.
569 (FlowBranching.IsParameterAssigned, SetParameterAssigned): Added
570 overloaded versions of these methods which take an additional
571 `string field_name' argument to check struct member.s
572 (VariableInfo): Implement the IVariable interface.
573 (VariableInfo.StructInfo): New public property. Returns the
574 MyStructInfo instance of the variable if it's a struct or null.
575 (Block.AddThisVariable): New public method. This is called from
576 Constructor.Emit() for non-static `struct' constructor which do
577 not have any initializer. It creates a special variable for the
578 "this" instance variable which will be checked by the flow
579 analysis code to ensure that all of the struct's fields are
580 initialized before control returns from the constructor.
581 (UsageVector): Added support for struct members. If a
582 variable/parameter is a struct with N members, we reserve a slot
583 in the usage vector for each member. A struct is considered fully
584 initialized if either the struct itself (slot 0) or all its
585 members are initialized.
587 2002-08-08 Martin Baulig <martin@gnome.org>
589 * driver.cs (Driver.MainDriver): Only report an error CS5001
590 if there were no compilation errors.
592 * codegen.cs (EmitContext.EmitContext): Use the DeclSpace's
593 `UnsafeContext' property to determine whether the parent is in
594 unsafe context rather than checking the parent's ModFlags:
595 classes nested in an unsafe class are unsafe as well.
597 2002-08-08 Martin Baulig <martin@gnome.org>
599 * statement.cs (UsageVector.MergeChildren): Distinguish between
600 `Breaks' and `Returns' everywhere, don't set `Breaks' anymore if
601 we return. Added test17() and test18() to test-154.cs.
603 2002-08-08 Martin Baulig <martin@gnome.org>
605 * typemanager.cs (TypeManager.FilterWithClosure): If we have
606 Family access, make sure the invoking type isn't a subclass of the
607 queried type (that'd be a CS1540).
609 * ecore.cs (Expression.MemberLookup): Added overloaded version of
610 this method which takes an additional `Type invocation_type'.
612 * expression.cs (BaseAccess.DoResolve): Use the base type as
613 invocation and query type.
614 (MemberAccess.DoResolve): If the lookup failed and we're about to
615 report a CS0122, try a lookup with the ec.ContainerType - if this
616 succeeds, we must report a CS1540.
618 2002-08-08 Martin Baulig <martin@gnome.org>
620 * ecore.cs (IMemberExpr): Added `bool IsInstance' property.
621 (MethodGroupExpr): Implement the IMemberExpr interface.
623 * expression (MemberAccess.ResolveMemberAccess): No need to have
624 any special code for MethodGroupExprs anymore, they're now
627 2002-08-08 Martin Baulig <martin@gnome.org>
629 * typemanager.cs (TypeManager.FilterWithClosure): Check Assembly,
630 Family, FamANDAssem and FamORAssem permissions.
631 (TypeManager.IsSubclassOrNestedChildOf): New public method.
633 2002-08-08 Martin Baulig <martin@gnome.org>

643 2002-08-07 Martin Baulig <martin@gnome.org>
645 * class.cs (FieldBase.Initializer): Renamed to `init' and made private.
646 (FieldBase.HasFieldInitializer): New public property.
647 (FieldBase.GetInitializerExpression): New public method. Resolves and
648 returns the field initializer and makes sure it is only resolved once.
649 (TypeContainer.EmitFieldInitializers): Call
650 FieldBase.GetInitializerExpression to get the initializer, this ensures
651 that it isn't resolved multiple times.
653 * codegen.cs (EmitContext): Added `bool IsFieldInitialier'. This tells
654 the resolving process (SimpleName/MemberLookup) that we're currently
655 emitting a field initializer (which must not access any instance members,
656 this is an error CS0236).
658 * ecore.cs (SimpleName.Error_ObjectRefRequired): Added EmitContext
659 argument, if the `IsFieldInitializer' flag is set, we must report and
660 error CS0236 and not an error CS0120.
662 2002-08-07 Martin Baulig <martin@gnome.org>
664 * ecore.cs (IMemberExpr): New public interface.
665 (FieldExpr, PropertyExpr, EventExpr): Implement IMemberExpr.
666 (SimpleName.SimpleNameResolve): Call MemberAccess.ResolveMemberAccess
667 if the expression is an IMemberExpr.
669 * expression.cs (MemberAccess.ResolveMemberAccess): Allow `left'
670 to be null, implicitly default to `this' if we're non-static in
671 this case. Simplified the code a lot by using the new IMemberExpr
672 interface. Also fixed bug #28176 here.
674 2002-08-06 Martin Baulig <martin@gnome.org>
676 * cs-parser.jay (SimpleLookup): Removed. We need to create
677 ParameterReferences during semantic analysis so that we can do a
678 type-only search when resolving Cast, TypeOf and SizeOf.
679 (block): Pass the `current_local_parameters' to the Block's
682 * class.cs (ConstructorInitializer): Added `Parameters parameters'
683 argument to the constructor.
684 (ConstructorInitializer.Resolve): Create a temporary implicit
685 block with the parameters.
687 * ecore.cs (SimpleName.SimpleNameResolve): Resolve parameter
688 references here if we aren't doing a type-only search.
690 * statement.cs (Block): Added constructor which takes a
691 `Parameters parameters' argument.
692 (Block.Parameters): New public property.
694 * support.cs (InternalParameters.Parameters): Renamed `parameters'
695 to `Parameters' and made it public readonly.
697 2002-08-06 Martin Baulig <martin@gnome.org>
699 * ecore.cs (Expression.Warning): Made this public as well.
701 * report.cs (Report.Debug): Print the contents of collections.
703 2002-08-06 Martin Baulig <martin@gnome.org>
705 * ecore.cs (Expression.ResolveFlags): New [Flags] enum. This is
706 used to tell Resolve() which kinds of expressions it may return.
707 (Expression.Resolve): Added overloaded version of this method which
708 takes a `ResolveFlags flags' argument. This can be used to tell
709 Resolve() which kinds of expressions it may return. Reports a
711 (Expression.ResolveWithSimpleName): Removed, use Resolve() with
712 ResolveFlags.SimpleName.
713 (Expression.Error118): Added overloaded version of this method which
714 takes a `ResolveFlags flags' argument. It uses the flags to determine
715 which kinds of expressions are allowed.
717 * expression.cs (Argument.ResolveMethodGroup): New public method.
718 Resolves an argument, but allows a MethodGroup to be returned.
719 This is used when invoking a delegate.
721 * TODO: Updated a bit.
723 2002-08-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
725 Fixed compilation with csc.
727 * ecore.cs: Expression.Error made public. Is this correct? Should
728 Warning be made public too?
730 * expression.cs: use ea.Location instead of ea.loc.
731 [FIXME: Filed as bug #28607: MCS must report these errors.]
733 2002-08-06 Martin Baulig <martin@gnome.org>
735 * ecore.cs (Expression.loc): Moved the location here instead of
736 duplicating it in all derived classes.
737 (Expression.Location): New public property.
738 (Expression.Error, Expression.Warning): Made them non-static and
739 removed the location argument.
740 (Expression.Warning): Added overloaded version which takes an
741 `int level' argument.
742 (Expression.Error118): Make this non-static and removed the
743 expression and location arguments.
744 (TypeExpr): Added location argument to the constructor.
746 * expression.cs (StaticCallExpr): Added location argument to
748 (Indirection, PointerArithmetic): Likewise.
749 (CheckedExpr, UnCheckedExpr): Likewise.
750 (ArrayAccess, IndexerAccess, UserCast, ArrayPtr): Likewise.
751 (StringPtr): Likewise.
754 2002-08-05 Martin Baulig <martin@gnome.org>
756 * expression.cs (BaseAccess.DoResolve): Actually report errors.
758 * assign.cs (Assign.DoResolve): Check whether the source
759 expression is a value or variable.
761 * statement.cs (Try.Resolve): Set ec.InTry/InCatch/InFinally
762 while resolving the corresponding blocks.
764 * interface.cs (Interface.GetInterfaceTypeByName): Actually report
765 an error, don't silently return null.
767 * statement.cs (Block.AddVariable): Do the error reporting here
768 and distinguish between CS0128 and CS0136.
769 (Block.DoResolve): Report all unused labels (warning CS0164).
770 (LabeledStatement): Pass the location to the constructor.
771 (LabeledStatement.HasBeenReferenced): New property.
772 (LabeledStatement.Resolve): Set it to true here.
774 * statement.cs (Return.Emit): Return success even after reporting
775 a type mismatch error (CS0126 or CS0127), this is what csc does and
776 it avoids confusing the users with any consecutive errors.
778 2002-08-05 Martin Baulig <martin@gnome.org>
780 * enum.cs (Enum.LookupEnumValue): Catch circular definitions.
782 * const.cs (Const.LookupConstantValue): Catch circular definitions.
784 * expression.cs (MemberAccess.DoResolve): Silently return if an
785 error has already been reported.
787 * ecore.cs (Expression.MemberLookupFinal): Silently return if an
788 error has already been reported.
790 2002-08-05 Martin Baulig <martin@gnome.org>
792 * statement.cs (UsageVector): Only initialize the `parameters'
793 vector if we actually have any "out" parameters.
795 2002-08-05 Martin Baulig <martin@gnome.org>
797 * expression.cs (Binary.ResolveOperator): When combining delegates,
798 they must have the same type.
800 2002-08-05 Martin Baulig <martin@gnome.org>
802 * typemanager.cs (TypeManager.GetArgumentTypes): Don't call
803 PropertyInfo.GetIndexParameters() on dynamic types, this doesn't
804 work with the ms runtime and we also don't need it: if we're a
805 PropertyBuilder and not in the `indexer_arguments' hash, then we
806 are a property and not an indexer.
808 * class.cs (TypeContainer.AsAccessible): Use Type.IsArray,
809 Type.IsPointer and Type.IsByRef instead of Type.HasElementType
810 since the latter one doesn't work with the ms runtime.
812 2002-08-03 Martin Baulig <martin@gnome.org>
814 Fixed bugs #27998 and #22735.
816 * class.cs (Method.IsOperator): New public field.
817 (Method.CheckBase): Report CS0111 if there's already a method
818 with the same parameters in the current class. Report CS0508 when
819 attempting to change the return type of an inherited method.
820 (MethodData.Emit): Report CS0179 if a method doesn't have a body
821 and it's not marked abstract or extern.
822 (PropertyBase): New abstract base class for Property and Indexer.
823 (PropertyBase.CheckBase): Moved here from Property and made it work
825 (PropertyBase.Emit): Moved here from Property.Emit, Indexer.Emit is
826 the same so we can reuse it there.
827 (Property, Indexer): Derive from PropertyBase.
828 (MethodSignature.inheritable_property_signature_filter): New delegate
829 to find properties and indexers.
831 * decl.cs (MemberCore.CheckMethodAgainstBase): Added `string name'
832 argument and improved error reporting.
834 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): Renamed to
835 EmptyReadOnlyParameters and made it a property.
837 * typemanager.cs (TypeManager.GetArgumentTypes): Added overloaded
838 version of this method which takes a `PropertyInfo indexer'.
839 (TypeManager.RegisterIndexer): New method.
841 * class.cs: Added myself as author of this file :-)
843 2002-08-03 Gonzalo Paniagua Javier <gonzalo@ximian.com>

855 (MemberBase.CheckParameters): Report errors if the accessibility
858 * delegate.cs (Delegate.Delegate): The default visibility is
859 internal for top-level types and private for nested types.
860 (Delegate.Define): Report errors if the accessibility checks fail.
862 * enum.cs (Enum.Enum): The default visibility is internal for
863 top-level types and private for nested types.
864 (Enum.DefineType): Compute the correct visibility.
866 * modifiers.cs (Modifiers.TypeAttr): Added a version of this
867 function which takes a `bool is_toplevel' instead of a TypeContainer.
869 * typemanager.cs (TypeManager.IsBuiltinType): `void' is also a
872 2002-08-02 Martin Baulig <martin@gnome.org>
874 * expression.cs (LocalVariableReferenc): Added constructor which
875 takes additional `VariableInfo vi' and `bool is_readonly' arguments.
876 (LocalVariableReference.IsReadOnly): New property.
877 (LocalVariableReference.DoResolveLValue): Report a CS1604 if the
878 variable is readonly, use our own readonly flag to do this; you can
879 use the new constructor to get a writable reference to a read-only
882 * cs-parser.jay (foreach_statement, using_statement): Get a writable
883 reference to the local variable.
885 2002-08-01 Miguel de Icaza <miguel@ximian.com>
887 * rootcontext.cs (ResolveCore): Also include System.Exception
889 * statement.cs (Block.Emit): Do not emit the dead-code warnings if
890 we reach an EmptyStatement.

913 `is_disposable' fields.
914 (Foreach.GetEnumeratorFilter): Set `hm.enumerator_type' and
915 `hm.is_disposable' if we're using the collection pattern.
916 (Foreach.EmitCollectionForeach): Use the correct type for the
917 enumerator's local variable, only emit the try/finally block if

929 whether it derives from System.Exception (CS0155).
930 (Catch.CatchType, Catch.IsGeneral): New public properties.
932 * typemanager.cs (TypeManager.exception_type): Added.
934 2002-07-31 Miguel de Icaza <miguel@ximian.com>

985 then use this argument.
987 * report.cs (Report.Debug): Renamed to conditional to "MCS_DEBUG".
989 * makefile.gnu (MCS_FLAGS): Include $(MCS_DEFINES), the user may
990 use this to specify /define options.

1096 (MethodData.ApplyAttributes): Likewise.
1097 (MethodData.ApplyObsoleteAttribute): Likewise.
1098 (MethodData.ApplyConditionalAttribute): Likewise.
1099 (MethodData.ApplyDllImportAttribute): Likewise.
1100 (MethodData.CheckAbstractAndExternal): Likewise.
1101 (MethodData.Define): Formerly knows as MemberBase.DefineMethod().
1102 (MethodData.Emit): Formerly known as Method.Emit().
1103 (MemberBase): Moved everything which was specific to a single
1104 accessor/method to MethodData.
1105 (Method): Create a new MethodData and call Define() and Emit() on it.
1106 (Property, Indexer, Event): Create a new MethodData objects for each
1107 accessor and call Define() and Emit() on them.
1109 2002-07-25 Martin Baulig <martin@gnome.org>
1111 Made MethodCore derive from MemberBase to reuse the code from there.
1112 MemberBase now also checks for attributes.
1114 * class.cs (MethodCore): Derive from MemberBase, not MemberCore.
1115 (MemberBase.GetMethodFlags): Moved here from class Method and marked
1117 (MemberBase.DefineAccessor): Renamed to DefineMethod(), added
1118 `CallingConventions cc' and `Attributes opt_attrs' arguments.

1133 (Method.CheckBase): Moved some code from Define() here, call
1134 DoDefineParameters() here.

1136 here to avoid some larger code duplication.
1137 (Property.Emit, Indexer.Emit): Call CheckAbstractAndExternal() to
1138 ensure that abstract and external accessors don't declare a body.
1140 * attribute.cs (Attribute.GetValidPieces): Make this actually work:
1141 `System.Attribute.GetCustomAttributes (attr.Type)' does a recursive
1142 lookup in the attribute's parent classes, so we need to abort as soon
1143 as we found the first match.
1144 (Attribute.Obsolete_GetObsoleteMessage): Return the empty string if
1145 the attribute has no arguments.
1147 * typemanager.cs (TypeManager.AddMethod): Now takes a MemberBase instead

1163 [FIXME: Filed as bug #28186: MCS must report this error.]
1165 2002-07-25 Martin Baulig <martin@gnome.org>
1167 * attribute.cs (Attribute.Conditional_GetConditionName): New static
1168 method to pull the condition name ouf of a Conditional attribute.

1174 (Method.ApplyConditionalAttribute, Method.ApplyObsoleteAttribute): New
1176 (Method.Define): Get and apply the Obsolete and Conditional attributes;
1177 if we're overriding a virtual function, set the new private variable
1178 `parent_method'; call the new TypeManager.AddMethod().
1180 * typemanager.cs (TypeManager.AddMethod): New static method. Stores
1181 the MethodBuilder and the Method in a PtrHashtable.
1182 (TypeManager.builder_to_method): Added for this purpose.
1183 (TypeManager.MethodFlags): Added IsObsoleteError.
1184 (TypeManager.GetMethodFlags): Added `Location loc' argument. Lookup
1185 Obsolete and Conditional arguments in MethodBuilders. If we discover
1186 an Obsolete attribute, emit an appropriate warning 618 / error 619 with
1187 the message from the attribute.
1189 2002-07-24 Martin Baulig <martin@gnome.org>
1191 * cs-tokenizer.cs: Eat up trailing whitespaces and one-line comments in
1192 preprocessor directives, ensure that the argument to #define/#undef is
1193 exactly one identifier and that it's actually an identifier.
1195 Some weeks ago I did a `#define DEBUG 1' myself and wondered why this
1198 2002-07-24 Martin Baulig <martin@gnome.org>
1200 * statement.cs (Foreach.ForeachHelperMethods): Added `Type element_type',
1201 initialize it to TypeManager.object_type in the constructor.
1202 (Foreach.GetEnumeratorFilter): Set `hm.element_type' to the return type
1203 of the `hm.get_current' method if we're using the collection pattern.
1204 (Foreach.EmitCollectionForeach): Use `hm.element_type' as the source type
1205 for the explicit conversion to make it work when we're using the collection
1206 pattern and the `Current' property has a different return type than `object'.
1209 2002-07-24 Martin Baulig <martin@gnome.org>
1211 * delegate.cs (Delegate.VerifyMethod): Simply return null if the method
1212 does not match, but don't report any errors. This method is called in
1213 order for all methods in a MethodGroupExpr until a matching method is
1214 found, so we don't want to bail out if the first method doesn't match.
1215 (NewDelegate.DoResolve): If none of the methods in the MethodGroupExpr
1216 matches, report the 123. Fixes #28070.
1218 2002-07-24 Martin Baulig <martin@gnome.org>
1220 * expression.cs (ArrayAccess.EmitStoreOpcode): Moved the
1221 TypeManager.TypeToCoreType() to the top of the method so the
1222 following equality checks will work. Fixes #28107.
1224 2002-07-24 Martin Baulig <martin@gnome.org>
1226 * cfold.cs (ConstantFold.DoConstantNumericPromotions): "If either
1227 operand is of type uint, and the other operand is of type sbyte,
1228 short or int, the operands are converted to type long." -
1229 Actually do what this comment already told us. Fixes bug #28106,
1232 2002-07-24 Martin Baulig <martin@gnome.org>
1234 * class.cs (MethodBase): New abstract class. This is now a base
1235 class for Property, Indexer and Event to avoid some code duplication
1236 in their Define() and DefineMethods() methods.
1237 (MethodBase.DoDefine, MethodBase.DefineAccessor): Provide virtual
1238 generic methods for Define() and DefineMethods().
1239 (FieldBase): Derive from MemberBase, not MemberCore.
1240 (Property): Derive from MemberBase, not MemberCore.
1241 (Property.DefineMethod): Moved all the code from this method to the
1242 new MethodBase.DefineAccessor(), just call it with appropriate
1244 (Property.Define): Call the new Property.DoDefine(), this does some
1245 sanity checks and we don't need to duplicate the code everywhere.
1246 (Event): Derive from MemberBase, not MemberCore.
1247 (Event.Define): Use the new MethodBase.DefineAccessor() to define the
1248 accessors, this will also make them work with interface events.
1249 (Indexer): Derive from MemberBase, not MemberCore.
1250 (Indexer.DefineMethod): Removed, call MethodBase.DefineAccessor() insstead.
1251 (Indexer.Define): Use the new MethodBase functions.
1253 * interface.cs (InterfaceEvent.InterfaceEvent): Added `Location loc'
1254 argument to the constructor.
1255 (Interface.FindMembers): Added support for interface events.
1256 (Interface.PopluateEvent): Implemented.
1258 Added test-149.cs for this. This also fixes bugs #26067 and #24256.
1260 2002-07-22 Miguel de Icaza <miguel@ximian.com>
1262 * class.cs (TypeContainer.AddMethod): Adding methods do not use IsValid,
1263 but this is required to check for a method name being the same as
1264 the containing class.
1268 2002-07-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1270 * interface.cs: initialize variable.
1272 2002-07-23 Martin Baulig <martin@gnome.org>
1274 Implemented the IndexerName attribute in interfaces.
1276 * class.cs (TypeContainer.DefineIndexers): Don't set the indexer
1277 name if this is an explicit interface implementation.
1278 (Indexer.InterfaceIndexerName): New public variable. If we're
1279 implementing an interface indexer, this is the IndexerName in that
1280 interface. Otherwise, it's the IndexerName.
1281 (Indexer.DefineMethod): If we're implementing interface indexer,
1282 set InterfaceIndexerName. Use the new Pending.IsInterfaceIndexer
1283 and Pending.ImplementIndexer methods.
1284 (Indexer.Define): Also define the PropertyBuilder if we're
1285 implementing an interface indexer and this is neither an explicit
1286 interface implementation nor do the IndexerName match the one in
1289 * pending.cs (TypeAndMethods): Added `MethodInfo [] need_proxy'.
1290 If a method is defined here, then we always need to create a proxy
1291 for it. This is used when implementing interface indexers.
1292 (Pending.IsInterfaceIndexer): New public method.
1293 (Pending.ImplementIndexer): New public method.
1294 (Pending.InterfaceMethod): Added `MethodInfo need_proxy' argument.
1295 This is used when implementing interface indexers to define a proxy
1297 (Pending.VerifyPendingMethods): Look in the `need_proxy' array and
1298 define a proxy if necessary.
1300 * interface.cs (Interface.IndexerName): New public variable.
1301 (Interface.PopulateIndexer): Set the IndexerName.
1302 (Interface.DefineIndexers): New private method. Populate all the
1303 indexers and make sure their IndexerNames match.
1305 * typemanager.cs (IndexerPropertyName): Added support for interface
1308 2002-07-22 Martin Baulig <martin@gnome.org>
1310 * codegen.cs (EmitContext.HasReturnLabel): New public variable.
1311 (EmitContext.EmitTopBlock): Always mark the ReturnLabel and emit a
1312 ret if HasReturnLabel.
1313 (EmitContext.TryCatchLevel, LoopBeginTryCatchLevel): New public
1316 * statement.cs (Do.Emit, While.Emit, For.Emit, Foreach.Emit): Save
1317 and set the ec.LoopBeginTryCatchLevel.
1318 (Try.Emit): Increment the ec.TryCatchLevel while emitting the block.
1319 (Continue.Emit): If the ec.LoopBeginTryCatchLevel is smaller than
1320 the current ec.TryCatchLevel, the branch goes out of an exception
1321 block. In this case, we need to use Leave and not Br.
1323 2002-07-22 Martin Baulig <martin@gnome.org>
1325 * statement.cs (Try.Emit): Emit an explicit ret after the end of the
1326 block unless the block does not always return or it is contained in
1327 another try { ... } catch { ... } block. Fixes bug #26506.
1328 Added verify-1.cs to the test suite.
1330 2002-07-22 Martin Baulig <martin@gnome.org>
1332 * statement.cs (Switch.TableSwitchEmit): If we don't have a default,
1333 then we do not always return. Fixes bug #24985.
1335 2002-07-22 Martin Baulig <martin@gnome.org>
1337 * expression.cs (Invocation.OverloadedResolve): Do the BetterFunction()
1338 lookup on a per-class level; ie. walk up the class hierarchy until we
1339 found at least one applicable method, then choose the best among them.
1340 Fixes bug #24463 and test-29.cs.
1342 2002-07-22 Martin Baulig <martin@gnome.org>
1344 * typemanager.cs (TypeManager.ArrayContainsMethod): Don't check the
1345 return types of the methods. The return type is not part of the
1346 signature and we must not check it to make the `new' modifier work.
1347 Fixes bug #27999, also added test-147.cs.
1348 (TypeManager.TypeToCoreType): Added TypeManager.type_type.
1350 * expression.cs (Invocation.DoResolve): Call TypeManager.TypeToCoreType()
1351 on the method's return type.
1353 2002-07-21 Martin Baulig <martin@gnome.org>
1355 * assign.cs: Make this work if the rightmost source is a constant and
1356 we need to do an implicit type conversion. Also adding a few more tests
1357 to test-38.cs which should have caught this.
1359 * makefile.gnu: Disable debugging, there's already the mcs-mono2.exe
1360 target in the makefile for this. The makefile.gnu is primarily intended
1361 for end-users who don't want to debug the compiler.
1363 2002-07-21 Martin Baulig <martin@gnome.org>
1365 * assign.cs: Improved the Assign class so it can now handle embedded
1366 assignments (X = Y = Z = something). As a side-effect this'll now also
1367 consume less local variables. test-38.cs now passes with MCS, added
1368 a few new test cases to that test.
1370 2002-07-20 Martin Baulig <martin@gnome.org>
1372 * expression.cs (Binary.EmitBranchable): Emit correct unsigned branch
1373 instructions. Fixes bug #27977, also added test-146.cs.
1375 2002-07-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1377 * cs-tokenizer.cs: fixed getHex ().
1379 2002-07-19 Martin Baulig <martin@gnome.org>
1381 * expression.cs (Invocation.EmitParams): Use TypeManager.LookupType(),
1382 not Type.GetType() to lookup the array type. This is needed when
1383 we're constructing an array of a user-defined type.
1384 (ArrayAccess.EmitDynamicInitializers): Only emit the Ldelema for
1385 single-dimensional arrays, but also for single-dimensial arrays of
1388 2002-07-19 Martin Baulig <martin@gnome.org>
1390 * expression.cs (New.DoEmit): Create a new LocalTemporary each time
1391 this function is called, it's not allowed to share LocalBuilders
1394 2002-07-19 Martin Baulig <martin@gnome.org>
1396 * expression.cs (Argument.Resolve): Report an error 118 when trying
1397 to pass a type as argument.
1399 2002-07-18 Martin Baulig <martin@gnome.org>
1401 * ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
1402 Conv_R_Un for the signed `long' type.
1404 2002-07-15 Miguel de Icaza <miguel@ximian.com>
1406 * expression.cs (MemberAccess.DoResolve): Do not reuse the field
1407 `expr' for the temporary result, as that will fail if we do
1408 multiple resolves on the same expression.
1410 2002-07-05 Miguel de Icaza <miguel@ximian.com>
1412 * ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
1413 ec.TypeContainer for looking up aliases.
1415 * class.cs (TypeContainer): Remove LookupAlias from here.
1417 * decl.cs (DeclSpace); Move here.
1419 2002-07-01 Miguel de Icaza <miguel@ximian.com>
1421 * class.cs (FindMembers): Only call filter if the constructor
1422 bulider is not null.
1424 Also handle delegates in `NestedTypes' now. Now we will perform
1425 type lookups using the standard resolution process. This also
1428 * decl.cs (DeclSpace.ResolveType): New type resolution routine.
1429 This uses Expressions (the limited kind that can be parsed by the
1430 tree) instead of strings.
1432 * expression.cs (ComposedCast.ToString): Implement, used to flag
1433 errors since now we have to render expressions.
1435 (ArrayCreation): Kill FormElementType. Use ComposedCasts in
1438 * ecore.cs (SimpleName.ToString): ditto.
1440 * cs-parser.jay: Instead of using strings to assemble types, use
1441 Expressions to assemble the type (using SimpleName, ComposedCast,
1442 MemberAccess). This should fix the type lookups in declarations,
1443 because we were using a different code path for this.
1445 * statement.cs (Block.Resolve): Continue processing statements
1446 even when there is an error.
1448 2002-07-17 Miguel de Icaza <miguel@ximian.com>
1450 * class.cs (Event.Define): Also remove the `remove' method from
1451 the list of pending items.
1453 * expression.cs (ParameterReference): Use ldarg.N (0..3) to
1454 generate more compact code.
1456 2002-07-17 Martin Baulig <martin@gnome.org>
1458 * const.cs (Const.LookupConstantValue): Add support for constant
1459 `unchecked' and `checked' expressions.
1460 Also adding test case test-140.cs for this.
1462 2002-07-17 Martin Baulig <martin@gnome.org>
1464 * statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
1465 check whether mi.ReturnType implements the IEnumerator interface; the
1466 `==' and the IsAssignableFrom() will fail in this situation.
1468 2002-07-16 Ravi Pratap <ravi@ximian.com>
1470 * ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix
1473 2002-07-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1475 * expression.cs: fixed bug #27811.
1477 2002-07-14 Miguel de Icaza <miguel@ximian.com>
1479 * expression.cs (ParameterReference.AddressOf): Patch from Paolo
1480 Molaro: when we are a ref, the value already contains a pointer
1481 value, do not take the address of it.
1483 2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1484 * removed mb-parser.jay and mb-tokenizer.cs
1486 Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
1488 * expression.cs: check against the building corlib void type.
1490 Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
1492 * ecore.cs: fix for valuetype static readonly fields: when
1493 initializing them, we need their address, not the address of a copy.
1495 Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
1497 * typemanager.cs: register also enum_type in corlib.
1499 Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
1501 * class.cs: allow calling this (but not base) initializers in structs.
1503 Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
1505 * ecore.cs: make sure we compare against the building base types
1508 Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
1510 * typemanager.cs: fix TypeToCoreType() to handle void and object
1511 (corlib gets no more typerefs after this change).
1513 2002-07-12 Miguel de Icaza <miguel@ximian.com>
1515 * expression.cs (ArrayCreation.EmitArrayArguments): use
1516 Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
1518 (ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
1519 Conv_Ovf_I_Un for the array arguments. Even if C# allows longs as
1520 array indexes, the runtime actually forbids them.
1522 * ecore.cs (ExpressionToArrayArgument): Move the conversion code
1523 for array arguments here.
1525 * expression.cs (EmitLoadOpcode): System.Char is a U2, use that
1526 instead of the default for ValueTypes.
1528 (New.DoEmit): Use IsValueType instead of
1529 IsSubclassOf (value_type)
1530 (New.DoResolve): ditto.
1531 (Invocation.EmitCall): ditto.
1533 * assign.cs (Assign): ditto.
1535 * statement.cs (Unsafe): Ok, so I got the semantics wrong.
1536 Statements *are* currently doing part of their resolution during
1539 Expressions do always resolve during resolve, but statements are
1540 only required to propagate resolution to their children.
1542 2002-07-11 Miguel de Icaza <miguel@ximian.com>
1544 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
1546 (LoadAssembly): Do not add the dll if it is already specified
1548 (MainDriver): Add the System directory to the link path at the end,
1549 after all the other -L arguments.
1551 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
1552 wrong opcode for loading bytes and bools (ldelem.i1 instead of
1553 ldelem.u1) and using the opposite for sbytes.
1555 This fixes Digger, and we can finally run it.
1557 * driver.cs (UnixParseOption): Move the option parsing here.
1558 (CSCParseOption): Implement CSC-like parsing of options.
1560 We now support both modes of operation, the old Unix way, and the
1561 new CSC-like way. This should help those who wanted to make cross
1564 The only thing broken is that /r:, /reference: and /lib: are not
1565 implemented, because I want to make those have the same semantics
1566 as the CSC compiler has, and kill once and for all the confussion
1567 around this. Will be doing this tomorrow.
1569 * statement.cs (Unsafe.Resolve): The state is checked during
1570 resolve, not emit, so we have to set the flags for IsUnsfe here.
1572 2002-07-10 Miguel de Icaza <miguel@ximian.com>
1574 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
1575 not catch the Error_ObjectRefRequired in SimpleName (as it is
1576 possible to have a class/instance variable name that later gets
1577 deambiguated), we have to check this here.
1579 2002-07-10 Ravi Pratap <ravi@ximian.com>
1581 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
1582 make static and put into Expression.
1584 (Event.Define): Register the private field of the event with the
1585 TypeManager so that GetFieldFromEvent can get at it.
1587 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
1588 keep track of the private field associated with an event which
1591 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
1594 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
1596 2002-07-10 Miguel de Icaza <miguel@ximian.com>
1598 * expression.cs (Binary.EmitBranchable): this routine emits the
1599 Binary expression in a branchable context. This basically means:
1600 we need to branch somewhere, not just get the value on the stack.
1602 This works together with Statement.EmitBoolExpression.
1604 * statement.cs (Statement.EmitBoolExpression): Use
1607 2002-07-09 Miguel de Icaza <miguel@ximian.com>
1609 * statement.cs (For): Reduce the number of jumps in loops.
1611 (For): Implement loop inversion for the For statement.
1613 (Break): We can be breaking out of a Try/Catch controlled section
1614 (foreach might have an implicit try/catch clause), so we need to
1615 use Leave instead of Br.
1617 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
1618 now). If the instace expression supports IMemoryLocation, we use
1619 the AddressOf method from the IMemoryLocation to extract the
1620 address instead of emitting the instance.
1622 This showed up with `This', as we were emitting the instance
1623 always (Emit) instead of the Address of This. Particularly
1624 interesting when This is a value type, as we dont want the Emit
1625 effect (which was to load the object).
1627 2002-07-08 Miguel de Icaza <miguel@ximian.com>
1629 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
1631 * statement.cs (Checked): Set the CheckedState during the resolve
1632 process too, as the ConvCast operations track the checked state on
1633 the resolve process, and not emit.
1635 * cs-parser.jay (namespace_member_declaration): Flag that we have
1636 found a declaration when we do. This is used to flag error 1529
1638 * driver.cs: Report ok when we display the help only.
1640 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
1642 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
1644 2002-07-04 Miguel de Icaza <miguel@ximian.com>
1646 * cs-tokenizer.cs (define): We also have to track locally the
1647 defines. AllDefines is just used for the Conditional Attribute,
1648 but we also need the local defines for the current source code.
1650 2002-07-03 Miguel de Icaza <miguel@ximian.com>
1652 * statement.cs (While, For, Do): These loops can exit through a
1653 Break statement, use this information to tell whether the
1654 statement is the last piece of code.
1656 (Break): Flag that we break.
1658 * codegen.cs (EmitContexts): New `Breaks' state variable.
1660 2002-07-03 Martin Baulig <martin@gnome.org>
1662 * class.cs (TypeContainer.MethodModifiersValid): Allow override
1663 modifiers in method declarations in structs. Otherwise, you won't
1664 be able to override things like Object.Equals().
1666 2002-07-02 Miguel de Icaza <miguel@ximian.com>
1668 * class.cs (Method, Property, Indexer): Do not allow the public
1669 modifier to be used in explicit interface implementations.
1671 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
1672 override modifiers in method declarations in structs
1674 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
1676 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
1677 integer or real overflow, report an error
1679 2002-07-02 Martin Baulig <martin@gnome.org>
1681 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
1682 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
1683 to tell the runtime about our newly created System.Object and
1684 System.ValueType types.
1686 2002-07-02 Miguel de Icaza <miguel@ximian.com>
1688 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
1689 struct instead of Ldarg/Starg.
1691 2002-07-02 Martin Baulig <martin@gnome.org>
1693 * expression.cs (Indirection.Indirection): Call
1694 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
1696 2002-07-02 Martin Baulig <martin@gnome.org>
1698 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
1699 ValueType, call TypeManager.TypeToCoreType() on it.
1700 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
1701 the OpCodes.Newarr argument.
1703 2002-07-02 Martin Baulig <martin@gnome.org>
1705 * expression.cs (Invocation.EmitCall): When compiling corlib,
1706 replace all calls to the system's System.Array type to calls to
1707 the newly created one.
1709 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
1710 System.Array methods.
1711 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
1712 from the system's System.Array type which must be replaced.
1714 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
1716 * typemanager.cs: load unverifiable_code_ctor so we can build
1717 corlib using the correct type. Avoid using GetTypeCode() with
1719 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
1720 TypeManager.object_type to allow building corlib.
1722 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
1724 * ecore.cs: handle System.Enum separately in LoadFromPtr().
1726 2002-07-01 Martin Baulig <martin@gnome.org>
1728 * class.cs: Make the last change actually work, we need to check
1729 whether `ifaces != null' to avoid a crash.
1731 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
1733 * class.cs: when we build structs without fields that implement
1734 interfaces, we need to add the interfaces separately, since there is
1735 no API to both set the size and add the interfaces at type creation
1738 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
1740 * expression.cs: the dimension arguments to the array constructors
1741 need to be converted if they are a long.
1743 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
1745 * class.cs: don't emit ldarg.0 if there is no parent constructor
1746 (fixes showstopper for corlib).
1748 2002-06-29 Martin Baulig <martin@gnome.org>
1750 MCS now compiles corlib on GNU/Linux :-)
1752 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
1753 ie. check for MethodImplOptions.InternalCall.
1755 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
1756 and TypeManager.attribute_type are null, so we must explicitly check
1757 whether parent is not null to find out whether it's an attribute type.
1758 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
1759 and SetBuilder, not only if the property is neither abstract nor external.
1760 This is necessary to set the MethodImplOptions on the accessor methods.
1761 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
1762 SetBuilder, see Property.Emit().
1764 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
1765 populate "System.Object", "System.ValueType" and "System.Attribute" since
1766 they've already been populated from BootCorlib_PopulateCoreTypes().
1768 2002-06-29 Martin Baulig <martin@gnome.org>
1770 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
1771 is the NullLiteral, we also need to make sure that target_type is not
1774 2002-06-29 Martin Baulig <martin@gnome.org>
1776 * rootcontext.cs (RootContext.ResolveCore): We must initialize
1777 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
1778 before calling BootstrapCorlib_ResolveDelegate ().
1780 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1782 * statement.cs: fixed build-breaker. All tests passed ok.
1784 2002-06-27 Martin Baulig <martin@gnome.org>
1786 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
1787 for System.Decimal when compiling corlib.
1789 2002-06-27 Martin Baulig <martin@gnome.org>
1791 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
1792 switch blocks which contain nothing but a default clause.
1794 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
1796 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
1798 2002-06-27 Martin Baulig <martin@gnome.org>
1800 * ecore.cs (PropertyExpr.PropertyExpr): Call
1801 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
1803 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
1804 is already a TypeBuilder.
1806 2002-06-27 Martin Baulig <martin@gnome.org>
1808 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
1809 `target_type == TypeManager.array_type', not IsAssignableFrom() in
1810 the "from an array-type to System.Array" case. This makes it work
1811 when compiling corlib.
1813 2002-06-27 Martin Baulig <martin@gnome.org>
1815 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
1816 non-static PropertyExpr, set its InstanceExpression. This makes
1817 the `ICollection.Count' property work in System/Array.cs.
1819 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
1821 * driver.cs: Made error handling more consistent. Errors now
1822 tracked by Report class, so many methods which used to return int
1823 now return void. Main() now prints success/failure and
1824 errors/warnings message.
1826 Renamed '--probe' compiler argument to '--expect-error'. Removed
1827 the magic number return values (123 and 124). Now, if the
1828 expected error occurs, the compiler exits with success (exit value
1829 0). If the compilation completes without seeing that particular
1830 error, the compiler exits with failure (exit value 1). The
1831 makefile in mcs/errors has been changed to handle the new behaviour.
1833 * report.cs: Made 'expected error' number a property and renamed
1834 it from 'Probe' to 'ExpectedError'.
1836 * genericparser.cs: Removed error handling support, since it is
1837 now all done by Report class.
1839 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
1840 class, so parse() no longer returns an int.
1842 * namespace.cs: Use Report.Error instead of GenericParser.error
1844 2002-06-22 Miguel de Icaza <miguel@ximian.com>
1846 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
1847 TypeContainer.AddOperator): At the front of the list put the
1848 explicit implementations, so they get resolved/defined first.
1850 2002-06-21 Miguel de Icaza <miguel@ximian.com>
1852 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
1853 interface type is implemented by this TypeContainer. Used during
1854 explicit interface implementation.
1856 (Property.Define, Indexer.Define, Method.Define): Validate that
1857 the given interface in the explicit implementation is one of the
1858 base classes for the containing type.
1860 Also if we are explicitly implementing an interface, but there is
1861 no match in the pending implementation table, report an error.
1863 (Property.Define): Only define the property if we are
1864 not explicitly implementing a property from an interface. Use the
1865 correct name also for those properties (the same CSC uses,
1866 although that is really not needed).
1868 (Property.Emit): Do not emit attributes for explicitly implemented
1869 properties, as there is no TypeBuilder.
1871 (Indexer.Emit): ditto.
1873 Hiding then means that we do not really *implement* a pending
1874 implementation, which makes code fail.
1876 2002-06-22 Martin Baulig <martin@gnome.org>
1878 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
1879 the return value of Object.GetType(). [FIXME: we need to do this whenever
1880 we get a type back from the reflection library].
1882 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
1884 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
1886 2002-06-20 Miguel de Icaza <miguel@ximian.com>
1888 * attribute.cs: Return null if we can not look up the type.
1890 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
1891 the interface types found.
1893 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
1894 interface types found.
1896 * typemanager.cs (GetInterfaces): Make this routine returns alll
1897 the interfaces and work around the lame differences between
1898 System.Type and System.Reflection.Emit.TypeBuilder in the results
1899 result for GetInterfaces.
1901 (ExpandInterfaces): Given an array of interface types, expand and
1902 eliminate repeated ocurrences of an interface. This expands in
1903 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
1906 2002-06-21 Martin Baulig <martin@gnome.org>
1908 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
1911 2002-06-21 Martin Baulig <martin@gnome.org>
1913 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
1914 and called with one of the core types, return the corresponding typebuilder for
1917 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
1920 2002-06-21 Martin Baulig <martin@gnome.org>
1922 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
1923 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
1924 (Expression.ConvertReferenceExplicit): Likewise.
1926 * expression.cs (ElementAccess.DoResolve): Likewise.
1927 (ElementAccess.DoResolveLValue): Likewise.
1929 2002-06-10 Martin Baulig <martin@gnome.org>
1931 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
1932 add the "value" parameter to the parameter list.
1934 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
1937 2002-06-19 Miguel de Icaza <miguel@ximian.com>
1939 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
1940 the argument to an int, uint, long or ulong, per the spec. Also
1941 catch negative constants in array creation.
1943 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
1945 * class.cs: do not allow the same interface to appear twice in
1946 the definition list.
1948 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
1950 * ecore.cs: don't use ldlen with System.Array.
1952 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
1954 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
1956 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
1958 * modifiers.cs: produce correct field attributes for protected
1959 internal. Easy fix so miguel can work on ther harder stuff:-)
1961 2002-06-18 Miguel de Icaza <miguel@ximian.com>
1963 * pending.cs: New file. Move the code from class.cs here.
1964 Support clearning the pending flag for all methods (when not doing
1965 explicit interface implementation).
1967 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
1969 * rootcontext.cs: added a couple more types needed to bootstrap.
1971 2002-06-17 Miguel de Icaza <miguel@ximian.com>
1973 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
1974 constructor in the type, instead of any constructor in the type
1975 hierarchy. Thanks to Paolo for finding this bug (it showed up as
1976 a bug in the Mono runtime when applying the params attribute).
1978 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1979 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
1981 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
1983 * expression.cs (Unary.ResolveOperator): Use TypeManager
1984 to resolve the type.
1986 2002-06-13 Ravi Pratap <ravi@ximian.com>
1988 * cs-parser.jay (enum_member_declaration): Pass in the attributes
1991 * enum.cs (AddEnumMember): Add support to store the attributes associated
1992 with each member too.
1994 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
1995 field builders too - this takes care of the enum member case.
1997 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
1999 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
2000 address-of operator on both value types and pointers.
2002 2002-06-10 Martin Baulig <martin@gnome.org>
2004 * interface.cs (Interface.PopulateIndexer): Add the indexer's
2005 PropertyBuilder to the `property_builders' list.
2007 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
2008 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
2009 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
2010 find any indexers which are inherited from an interface.
2012 2002-06-09 Martin Baulig <martin@gnome.org>
2014 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
2015 the same type as the constant if necessary. There's also a test-130.cs
2018 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
2020 * typemanager.cs (TypeManager.ChangeType): Previously known as
2021 Enum.ChangeEnumType().
2023 2002-06-09 Martin Baulig <martin@gnome.org>
2025 * expression.cs (Cast.TryReduce): Added support for consts.
2027 2002-06-08 Ravi Pratap <ravi@ximian.com>
2029 * class.cs (Accessor): Hold attributes information so we can pass
2032 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
2033 Modify to pass in attributes attached to the methods.
2035 (add_accessor_declaration, remove_accessor_declaration): Ditto.
2037 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
2038 to handle the Accessor kind :-)
2040 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
2042 2002-06-08 Martin Baulig <martin@gnome.org>
2044 * expression.cs (Unary.TryReduceNegative): Added support for
2047 2002-06-08 Martin Baulig <martin@gnome.org>
2049 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
2050 name can't be found in the `defined_names' - the caller will do a
2051 MemberLookup in this case and thus find methods in System.Enum
2052 such as Enum.IsDefined().
2054 2002-06-08 Martin Baulig <martin@gnome.org>
2056 * enum.cs (Enum.ChangeEnumType): This is a custom version of
2057 Convert.ChangeType() which works with TypeBuilder created types.
2058 (Enum.LookupEnumValue, Enum.Define): Use it here.
2060 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
2061 `TypeBuilder.BaseType != null' check.
2062 (TypeContainer.FindMembers): Only lookup parent members if we
2063 actually have a parent.
2064 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
2065 (ConstructorInitializer.Resolve): Likewise.
2067 * interface.cs (Interface.FindMembers): Added
2068 `TypeBuilder.BaseType != null' check.
2070 * rootcontext.cs (RootContext.ResolveCore): Added
2071 "System.Runtime.CompilerServices.IndexerNameAttribute" to
2072 classes_second_stage.
2074 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
2075 debug_type and trace_type when compiling with --nostdlib.
2077 2002-06-07 Martin Baulig <martin@gnome.org>
2079 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
2080 (AddField): Set it to true when adding a non-static field.
2081 (DefineType): Use `have_nonstatic_fields' to find out whether we
2082 have non-static fields, not `Fields != null'.
2084 2002-06-02 Miguel de Icaza <miguel@ximian.com>
2086 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
2087 dereferencing a null on the static-field code path)
2089 2002-05-30 Martin Baulig <martin@gnome.org>
2091 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
2092 to take command line arguments. Use reflection to call the new
2093 custom `Initialize' function on the symbol writer and pass it the
2094 command line arguments.
2096 * driver.cs (--debug-args): New command line argument to pass command
2097 line arguments to the symbol writer.
2099 2002-05-28 Miguel de Icaza <miguel@ximian.com>
2101 * assign.cs (DoResolve): Forgot to do the implicit conversion to
2102 the target type for indexers and properties. Thanks to Joe for
2105 2002-05-27 Miguel de Icaza <miguel@ximian.com>
2107 * typemanager.cs (MethodFlags): returns the method flags
2108 (Obsolete/ShouldIgnore) that control warning emission and whether
2109 the invocation should be made, or ignored.
2111 * expression.cs (Invocation.Emit): Remove previous hack, we should
2112 not do this on matching a base type, we should do this based on an attribute
2114 Only emit calls to System.Diagnostics.Debug and
2115 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
2116 on the command line.
2118 * rootcontext.cs: Global settings for tracing and debugging.
2120 * cs-tokenizer.cs (define): New utility function to track
2121 defines. Set the global settings for TRACE and DEBUG if found.
2123 2002-05-25 Ravi Pratap <ravi@ximian.com>
2125 * interface.cs (Populate*): Pass in the TypeContainer as well as
2126 the DeclSpace as parameters so that we can create EmitContexts and
2127 then use that to apply attributes etc.
2129 (PopulateMethod, PopulateEvent, PopulateProperty)
2130 (PopulateIndexer): Apply attributes everywhere.
2132 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
2135 (ApplyAttributes): Update accordingly.
2137 We now apply interface attributes for all members too.
2139 2002-05-26 Miguel de Icaza <miguel@ximian.com>
2141 * class.cs (Indexer.Define); Correctly check if we are explicit
2142 implementation (instead of checking the Name for a ".", we
2143 directly look up if the InterfaceType was specified).
2145 Delay the creation of the PropertyBuilder.
2147 Only create the PropertyBuilder if we are not an explicit
2148 interface implementation. This means that explicit interface
2149 implementation members do not participate in regular function
2150 lookups, and hence fixes another major ambiguity problem in
2151 overload resolution (that was the visible effect).
2153 (DefineMethod): Return whether we are doing an interface
2156 * typemanager.cs: Temporary hack until we get attributes in
2157 interfaces (Ravi is working on that) and we get IndexerName
2158 support in interfaces.
2160 * interface.cs: Register the indexers as properties.
2162 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
2163 warning, I have verified that this is a bug in the .NET runtime
2164 (JavaScript suffers of the same problem).
2166 * typemanager.cs (MemberLookup): When looking up members for
2167 interfaces, the parent of an interface is the implicit
2168 System.Object (so we succeed in searches of Object methods in an
2169 interface method invocation. Example: IEnumerable x; x.ToString
2172 2002-05-25 Miguel de Icaza <miguel@ximian.com>
2174 * class.cs (Event): Events should also register if they do
2175 implement the methods that an interface requires.
2177 * typemanager.cs (MemberLookup); use the new GetInterfaces
2180 (GetInterfaces): The code used to lookup interfaces for a type is
2181 used in more than one place, factor it here.
2183 * driver.cs: Track the errors at the bottom of the file, we kept
2186 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
2187 instance if the method we are calling is static!
2189 2002-05-24 Miguel de Icaza <miguel@ximian.com>
2191 * attribute.cs (ApplyAttributes): Make this function filter out
2192 the IndexerName attribute (as that attribute in reality is never
2193 applied) and return the string constant for the IndexerName
2196 * class.cs (TypeContainer.Emit): Validate that all the indexers
2197 have the same IndexerName attribute, and if so, set the
2198 DefaultName attribute on the class.
2200 * typemanager.cs: The return value might contain other stuff (not
2201 only methods). For instance, consider a method with an "Item"
2202 property and an Item method.
2204 * class.cs: If there is a problem with the parameter types,
2207 2002-05-24 Ravi Pratap <ravi@ximian.com>
2209 * ecore.cs (ImplicitConversionExists): Wrapper function which also
2210 looks at user defined conversion after making a call to
2211 StandardConversionExists - we need this for overload resolution.
2213 * expression.cs : Update accordingly the various method calls.
2215 This fixes 2 bugs filed against implicit user defined conversions
2217 2002-05-22 Miguel de Icaza <miguel@ximian.com>
2219 * statement.cs: Track the result of the assignment.
2221 2002-05-21 Miguel de Icaza <miguel@ximian.com>
2223 * expression.cs (MemberAccess): Improved error reporting for
2224 inaccessible members.
2226 2002-05-22 Martin Baulig <martin@gnome.org>
2228 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
2229 itself with debugging support.
2231 2002-05-22 Martin Baulig <martin@gnome.org>
2233 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
2234 Removed, this isn't needed anymore.
2236 2002-05-20 Martin Baulig <martin@gnome.org>
2238 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
2239 be underlying type for an enum.
2241 2002-05-20 Miguel de Icaza <miguel@ximian.com>
2243 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
2244 that splits out the loading of just the core types.
2246 * rootcontext.cs (ResolveCore): Split the struct resolution in
2247 two, so we can load the enumeration underlying types before any
2250 * expression.cs (Is): Bandaid until we fix properly Switch (see
2251 bug #24985 for details).
2253 * typemanager.cs (ImplementsInterface): The hashtable will contain
2254 a null if there are no interfaces implemented.
2256 2002-05-18 Miguel de Icaza <miguel@ximian.com>
2258 * cs-parser.jay (indexer_declarator): It is fine to have array
2261 2002-05-17 Miguel de Icaza <miguel@ximian.com>
2263 * typemanager.cs: (RegisterBuilder): New function used to register
2264 TypeBuilders that implement interfaces. Since
2265 TypeBuilder.GetInterfaces (as usual) does not work with lame
2267 (AddUserType): register interfaces.
2269 (ImplementsInterface): Use the builder_to_ifaces hash if we are
2270 dealing with TypeBuilder. Also, arrays are showing up as
2271 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
2272 methods can not be invoked on them!
2274 * ecore.cs (ExplicitReferenceConversionExists): Made public.
2275 (ImplicitReferenceConversionExists): Split out from
2276 StandardConversionExists.
2278 * expression.cs (As): We were only implementing one of the three
2279 cases for the as operator. We now implement them all.
2280 (Is): Implement the various other cases for Is as well.
2282 * typemanager.cs (CACHE): New define used to control if we want or
2283 not the FindMembers cache. Seems to have a negative impact on
2284 performance currently
2286 (MemberLookup): Nested types have full acess to
2287 enclosing type members
2289 Remove code that coped with instance/static returns for events, we
2290 now catch this in RealFindMembers.
2292 (RealFindMembers): only perform static lookup if the instance
2293 lookup did not return a type or an event.
2295 2002-05-17 Miguel de Icaza <miguel@ximian.com>
2297 * assign.cs (CompoundAssign): We pass more semantic information
2298 now to Compound Assignments than we did before: now we have all
2299 the information at hand, and now we resolve the target *before* we
2300 do the expression expansion, which allows the "CacheValue" method
2301 to have the effect we intended (before, a [x] += 1 would generate
2302 two differen ArrayAccess expressions from the ElementAccess,
2303 during the resolution process).
2305 (CompoundAssign.DoResolve): Resolve target and original_source here.
2307 2002-05-16 Miguel de Icaza <miguel@ximian.com>
2309 * expression.cs (ArrayAccess): dropped debugging information.
2311 * typemanager.cs: Small bug fix: I was always returning i_members,
2312 instead of one of i_members or s_members (depending on which had
2315 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
2316 method is invoked before any code generation takes place, and it
2317 is a mechanism to inform that the expression will be invoked more
2318 than once, and that the method should use temporary values to
2319 avoid having side effects
2321 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
2323 * ecore.cs (Expression.CacheTemporaries): Provide empty default
2326 * expression.cs (Indirection, ArrayAccess): Add support for
2327 CacheTemporaries in these two bad boys.
2329 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
2331 (StoreFromPtr): Handle stobj as well.
2333 * expression.cs (UnaryMutator): Share more code.
2335 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
2336 down: I was not tracking the Filter function as well, which
2337 was affecting the results of the cache.
2339 2002-05-15 Miguel de Icaza <miguel@ximian.com>
2341 * attribute.cs: Remove the hack to handle the CharSet property on
2344 2002-05-14 Miguel de Icaza <miguel@ximian.com>
2346 * attribute.cs (DoResolve): More uglyness, we now only try to
2347 resolve the attribute partially, to extract the CharSet
2348 information (only if we are a StructLayout attribute). Otherwise
2350 (GetExtraTypeInfo): Add some code to conditionally kill in the
2351 future this. I am more and more convinced that the .NET
2352 framework has special code to handle the attribute setting on
2355 * expression.cs (IsParamsMethodApplicable): Revert my previous
2356 foreach change here, it was wrong.
2358 2002-05-13 Miguel de Icaza <miguel@ximian.com>
2360 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
2361 (pp_expr): do not abort on unknown input, just return.
2362 (eval): abort if there are pending chars.
2364 * attribute.cs (Attribute.Resolve): Positional parameters are
2365 optional. Deal with that case.
2367 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
2368 the Ansi/Unicode/Auto information for the type.
2370 (TypeContainer.DefineType): instantiate the EmitContext here, as
2371 we will be using it during the type definition (to resolve
2372 attributes) and during the emit phase.
2374 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
2375 to pull type information out of the attributes
2377 (Attribute.Resolve): track the constructor builder, and allow for
2378 multiple invocations (structs and classes will use this).
2380 * ecore.cs (MemberLookupFinal): new version with all the
2381 parameters customizable.
2383 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
2384 constructors. Return if the result value is null (as the error
2385 would have been flagged already by MemberLookupFinal)
2387 Do not allow instances of abstract classes or interfaces to be
2390 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
2391 We have to compare the assembly property here when dealing with
2392 FamANDAssem and Assembly access modifiers, because we might be
2393 creating an assembly from *modules* (that means that we are not
2394 getting TypeBuilders for types defined in other modules that are
2395 part of this assembly).
2397 (Method.Emit): If the method is marked abstract and has a body,
2400 (TypeContainer.DefineMembers): If both the defined member and the
2401 parent name match are methods, then do not emit any warnings: let
2402 the Method.Define routine take care of flagging warnings. But if
2403 there is a mismatch (method overrides something else, or method is
2404 overriwritten by something, then emit warning).
2406 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
2407 set to null, this means `do not check for the return type on the
2410 (Method.Define): set the return type for the method signature to
2411 null, so that we get methods with the same name and parameters and
2412 different return types. This is used to flag warning 114 (you are
2413 hiding a method, and you probably want to use the new/override
2416 * typemanager.cs (MemberLookup): Implemented proper access
2417 control, closing a long standing set of bug reports. The problem
2418 was that the Framework only has two bits: Public and NonPublic,
2419 and NonPublic includes private and protected methods, but we need
2420 to enforce the FamANDAssem, FamOrAssem and Family.
2422 2002-05-11 Miguel de Icaza <miguel@ximian.com>
2424 * statement.cs (GotoCase): Return true: Ammounts to giving up
2425 knowledge on whether we return or not, and letting the other case
2426 be responsible for it.
2428 2002-05-10 Miguel de Icaza <miguel@ximian.com>
2430 * driver.cs: Do not load directories for each file processed, only
2431 do it if there is a pattern.
2433 * ecore.cs: Report readonly assigns here as well, as we might have
2434 been resolved only by MemberAccess.
2436 (SimpleName.SimpleNameResolve): Also be useful for LValue
2437 resolution. We need this to propagate assign to local readonly variables
2439 * typemanager.cs: Use a ptrhashtable for the criteria, because we
2440 do not want to reuse potential criteria memory.
2442 * class.cs (MyEventBuilder): Set reflected_type;
2444 * ecore.cs (Constantify): Added support for constifying bools.
2446 (RootContext.LookupType): Added a cache for values looked up in
2447 the declaration space.
2449 * typemanager.cs (FindMembers): Now is a front-end to
2450 RealFindMembers, and provides a two-level hashtable-based cache to
2453 15% performance improvement: from 22.5 to 19.2 seconds.
2455 * expression.cs (IsParamsMethodApplicable): use foreach.
2456 (Invocation.DoResolve): ditto.
2457 (New.DoResolve): ditto.
2458 (ArrayCreation.DoResolve): ditto.
2460 * ecore.cs (FindMostEncompassingType): use foreach.
2462 * delegate.cs (NewDelegate.DoResolve): Use foreach
2464 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
2465 (RemoveMethods): use foreach.
2467 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
2468 nested foreach statements instead of for, and also break out of
2469 the inner loop once a match is found.
2471 (Invocation.OverloadResolve): Use foreach, simplify the code.
2473 2002-05-08 Miguel de Icaza <miguel@ximian.com>
2475 * cfold.cs (BinaryFold): During an enumeration evaluation context,
2476 we actually unwrap the expression to allow for extra information
2479 * expression.cs: Use Shr_Un on unsigned operations.
2481 2002-05-08 Ravi Pratap <ravi@ximian.com>
2483 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
2484 applicable operators was not being considered correctly. This closes
2485 the bug Miguel reported.
2487 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
2489 * attribute.cs: check that the type derives from System.Attribute
2490 and report the correct error in that case (moved the duplicate code to
2491 its own method, too).
2493 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
2495 * attribute.cs: lookup attribute type name as the spec says: first the
2496 bare attribute name and then name + "Attribute" (nant compiles with
2497 mcs after this fix).
2499 2002-05-07 Miguel de Icaza <miguel@ximian.com>
2501 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
2502 Because of the way we parse things, we should try to see if a
2503 UIntConstant can fit in an integer.
2505 2002-05-07 Ravi Pratap <ravi@ximian.com>
2507 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
2508 when we are in an explicit context.
2510 (ConvertReferenceExplicit): When converting from Iface type S to Class
2511 T make sure the rules are implemented as an OR.
2513 * parameter.cs (ParameterType): Make it a property for now although the
2514 purpose really isn't anything immediate.
2516 * expression.cs (Is*Applicable): Do better checking on the parameter type
2517 of a ref/out parameter. The ones from the system assemblies are already
2518 marked with the correct type so we don't need to do any correction.
2520 * ecore.cs (StandardConversionExists): Conversion from Interface types to
2521 the object type is standard too so include that.
2523 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2525 * ecore.cs (StandardConversionExists): Augment with missing code:
2526 deal with IntConstant, LongConstants and Enumerations.
2528 * assign.cs: Report the error, instead of failing silently
2530 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
2531 typecontainer that they are declared, because the
2532 typecontainer/namespace will have the list of using clauses that
2535 Assembly Attributes were escaping the normal registration
2538 (EmitCode): Apply attributes within an EmitContext that represents
2539 the container they were declared on.
2541 * cs-parser.jay: Track bases for structs. How did I get this wrong?
2543 2002-05-06 Ravi Pratap <ravi@ximian.com>
2545 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
2546 Revamp completely - make much cleaner as we now operate only
2549 (FindMostSpecificSource, FindMostSpecificTarget): New methods
2550 to implement the logic detailed in the spec more correctly.
2552 (UserDefinedConversion): Update accordingly.
2554 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2556 * statement.cs: Return flow analysis information up.
2558 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
2561 (token): Do not consume an extra character before calling
2564 2002-05-06 Piers Haken <piersh@friskit.com>
2566 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
2568 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2570 * class.cs (Constructor.Emit): Set the IsStatic flag in the
2571 EmitContext during the instance constructor initializer
2572 resolution, to stop access to instance variables.
2574 This is mandated by the spec, last paragraph of the `constructor
2575 initializers' section.
2577 2002-05-05 Miguel de Icaza <miguel@ximian.com>
2579 * cs-parser.jay, class.cs (Accessor): new class used to represent
2580 an accessor (get or set). In the past we used `null' to represent
2581 a missing accessor. But this is ambiguous because there was no
2582 way to tell in abstract indexers/properties if one of them was
2585 Now there is a way of addressing that.
2587 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
2588 instead of FindMembers.
2590 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
2591 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
2593 * attribute.cs: Treat indexers and properties as the same in terms
2594 of applying attributes
2596 * ecore.cs (FindMostEncompassedType): Use statically initialized
2597 EmptyExpressions()s like we do elsewhere to avoid creating useless
2598 objects (and we take this out of the tight loop).
2600 (GetConversionOperators): Move the code to extract the actual
2601 operators to a separate routine to clean things up.
2603 2002-05-04 Miguel de Icaza <miguel@ximian.com>
2605 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
2606 events are always registered FieldBuilders.
2608 * class.cs (FieldBase): New class shared by Fields
2610 * delegate.cs: If we are a toplevel delegate, use our full name.
2611 If we are a nested delegate, then only use our tail name.
2613 2002-05-02 Ravi Pratap <ravi@ximian.com>
2615 * expression.cs (IsApplicable): Ensure that we add the "&" to
2616 ref/out types before comparing it with the type of the argument.
2618 (IsParamsMethodApplicable): Ditto.
2620 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
2623 * delegate.cs : Handle the case when we have more than one applicable
2624 method. Flag an error only when we finish checking all.
2626 2002-05-02 Miguel de Icaza <miguel@ximian.com>
2628 * expression.cs: Add support for boolean static initializers.
2630 2002-05-01 Miguel de Icaza <miguel@ximian.com>
2632 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
2634 * parameter.cs (ComputeParameterTypes,
2635 ComputeAndDefineParameterTypes): Better error handling: now we
2636 clear the `types' cache if we fail during any of the type lookups.
2637 We also return the status code correctly to our caller
2639 * delegate.cs: If we fail to define a delegate, abort the extra
2642 * expression.cs (Binary.ResolveOperator): for
2643 operator==(object,object) and operator !=(object, object) we also
2644 have to verify that there is an implicit conversion from one to
2647 (ArrayAccess.DoResolve): Array Access can operate on
2650 2002-04-30 Miguel de Icaza <miguel@ximian.com>
2652 * assign.cs (CompoundAssign): A new class used as a "flag" that
2653 the assignment actually is happening as part of a compound
2654 assignment operator.
2656 During compound assignment, a few new rules exist to enable things
2663 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
2664 to the type of x) if y is implicitly convertible to the type of x,
2665 and the operator is a builtin operator and the return type of the
2666 operator is explicitly convertible to the type of x.
2668 * rootcontext.cs: Reset warning level to 2. 4 catches various
2669 "interesting" features in mcs, we must clean this up at some
2670 point, but currently am trying to kill other bugs ;-)
2672 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
2673 in container classes as well.
2675 * expression.cs (Binary.ResolveOperator): Handle string case
2676 before anything else (as operator overloading does emit an error
2677 before doing anything else).
2679 This code could go away when we move to a table driven model, but
2680 i could not come up with a good plan last night.
2682 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
2684 * typemanager.cs (CSharpName): reimplementation using regex.
2685 * class.cs: added null check for fields in Emit
2686 * rootcontext.cs: set warninglevel to 4
2688 2002-04-29 Miguel de Icaza <miguel@ximian.com>
2690 * typemanager.cs (CSharpName): reimplemented with Lupus
2693 2002-04-28 Miguel de Icaza <miguel@ximian.com>
2695 * statement.cs (If): correclty implement Resolve, because we were
2696 not catching sem errors in there. The same process is needed
2698 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
2701 (Statement.Warning_DeadCodeFound): Factorize code.
2702 (While): Report dead code here too.
2704 (Statement): Added Resolve virtual method to allow
2705 for resolution split from the emit code.
2707 2002-04-26 Miguel de Icaza <miguel@ximian.com>
2709 * statement.cs (EmitBoolExpression): No longer try to resolve the
2711 (MakeBoolean): New utility function that resolve, implicitly
2712 converts to boolean and tags the expression.
2715 (If, Do): Implement dead code elimination.
2716 (While): Implement loop inversion
2718 (Do, While, For, If): Resolve the expression prior to calling our
2721 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
2724 - added method Report28 (warning: program has more than one entry point)
2725 - added method IsEntryPoint, implements paragraph 10.1 of the spec
2726 - modified method Method.Define, the part at the end of the method
2728 * rootcontext.cs: added static public Location EntryPointLocation;
2730 * ../errors/cs0028.cs : Add test case for the above warning.
2733 - modified method CSharpName to allow arrays of primitive type to
2734 be printed nicely (e.g. instead of System.Int32[][] it now prints
2736 - added method CSharpSignature: returns the signature of a method
2737 in string format to be used in reporting errors, warnings, etc.
2739 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
2742 2002-04-26 Ravi Pratap <ravi@ximian.com>
2744 * delegate.cs (Define): Fix extremely silly bug where I was
2745 setting the type of the 'object' parameter of the BeginInvoke
2746 method to System.IAsyncResult instead of System.Object ;-)
2748 2002-04-26 Miguel de Icaza <miguel@ximian.com>
2750 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
2753 (Constructor.Emit): return if we fail to initialize the
2754 constructor. Another door closed!
2756 * expression.cs (New.DoResolve): Improve error message (from -6 to
2757 1501). Use DeclaredOnly lookup to find the exact constructor.
2759 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
2760 loop. This is useful.
2762 * cs-parser.jay: Adjust the default parameters so that destructors
2763 have the proper signature.
2765 2002-04-26 Martin Baulig <martin@gnome.org>
2767 * driver.cs (LoadAssembly): If `assembly' contains any characters
2768 which are only valid in path names and not in assembly names
2769 (currently slash, backslash and point), use Assembly.LoadFrom ()
2770 instead of Assembly.Load () on the `assembly' (before iteration
2771 over the link_paths).
2773 2002-04-26 Martin Baulig <martin@gnome.org>
2775 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
2777 2002-04-25 Miguel de Icaza <miguel@ximian.com>
2779 * class.cs (Property): use the new typemanager.MemberLookup
2781 (TypeContainer.MemberLookup): Implement using the
2782 TypeManager.MemberLookup now.
2784 * typemanager.cs: Make MemberLookup a function of the TypeManager,
2785 and return MemberInfos, so that these can be used without an
2786 EmitContext (what we had before).
2788 2002-04-24 Miguel de Icaza <miguel@ximian.com>
2790 * expression.cs: Fix the case where the argument to params if the
2791 type of the params. I omitted handling this before. Fixed
2793 2002-04-22 Miguel de Icaza <miguel@ximian.com>
2795 * driver.cs: Call BootCorlib_PopulateCoreType
2797 * class.cs (Property.CheckBase): Check for properties only, not
2800 * interface.cs: Temporary hack: try/catch around the
2801 CustomAttributeBuilder, because I am getting an exception that I
2804 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
2805 types whose definitions are required to be there (attributes are
2806 defined before standard types).
2808 Compute definitions as we boot the various types, as they are used
2809 immediately (value_type class will need object_type, but if we do
2810 not initialize object_type, we will pass a null, which will let
2811 the runtime pick the System.Object from the existing corlib, which
2812 is not what we want).
2814 2002-04-22 Patrik Torstensson <totte@labs2.com>
2816 * cs-tokenizer.cs: fixed a number of trim() issues.
2818 2002-04-22 Ravi Pratap <ravi@ximian.com>
2820 * expression.cs (Argument.Type): Ensure that we return the correct
2821 type when we have out or ref parameters [in which case we
2824 2002-04-22 Miguel de Icaza <miguel@ximian.com>
2826 * class.cs (Property, Indexer): Allow extern modifier in there.
2828 * typemanager.cs (InitBaseTypes): Initializes object_type and
2829 value_type, since those will be used early on during the bootstrap
2830 process to compile corlib.
2832 (InitCoreTypes): Move code from here to InitBaseTypes.
2834 2002-04-21 Miguel de Icaza <miguel@ximian.com>
2836 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
2837 single-dimension arrays as using the ldlen opcode.
2839 Daniel Lewis discovered this optimization.
2841 * typemanager.cs: Add signature for System.Array::get_Length
2843 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2845 * statement.cs: report the error when the foreach does not apply to an
2846 array nor a collection.
2848 2002-04-19 Miguel de Icaza <miguel@ximian.com>
2850 * expression.cs: Add implicit conversions to the operator ~.
2852 * constant.cs (DecimalConstant.Emit): Emit decimal value.
2854 * typemanager.cs: Locate the decimal constructor.
2856 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2858 * attribute.cs: use the new property of TypeOf.
2859 * expression.cs: added 'get' property around typearg.
2861 These changes fix a build breaker reported by NickD. Is this the
2862 correct way to fix? If not, please, revert my changes and make it
2865 2002-04-17 Miguel de Icaza <miguel@ximian.com>
2867 * attribute.cs: Add support for typeof in attribute invocations.
2868 I am not sure that this is right though.
2870 2002-04-14 Duncan Mak <duncan@ximian.com>
2872 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
2873 Binary.Operator.Division case.
2875 2002-04-13 Ravi Pratap <ravi@ximian.com>
2877 * class.cs (DefineType): Ensure that we do a proper check on
2878 attribute types and also register it with the TypeManager.
2880 (TypeContainer.Targets): The default for attribute types is
2881 AttributeTargets.All.
2883 * attribute.cs (ApplyAttributes): Registering the attribute type
2884 is done elsewhere, not when we discover we have a Usage attribute.
2886 2002-04-12 Ravi Pratap <ravi@ximian.com>
2888 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
2889 and get rid of is_delegate parameter.
2891 * everywhere : update.
2893 2002-04-12 Ravi Pratap <ravi@ximian.com>
2895 * cs-parser.jay (compilation_unit): Revamp completely to use
2896 some new ideas that I got from Rhys' grammar to solve the problems
2897 with assembly level attributes.
2899 (outer_declaration): New grammar production.
2901 (attribute_sections): Add.
2903 (opt_attributes): Base on attribute_sections
2905 (namespace_declaration): Allow opt_attributes to tackle the case
2906 when we have assembly level attributes - we are clever in this
2909 * attribute.cs (ApplyAttributes): Do not worry about assembly
2910 attributes in the non-global context.
2912 * rootcontext.cs (AddGlobalAttributes): Go back to using this
2913 instead of SetGlobalAttributes.
2915 * class.cs, rootcontext.cs : Ensure we define and generate
2916 attribute types before anything else.
2918 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
2919 and flag the new error -20 for the case when the attribute type
2920 does not have valid targets specified. csc does not catch this.
2922 * ../errors/errors.txt : update for error # -20
2924 2002-04-11 Ravi Pratap <ravi@ximian.com>
2926 * support.cs (InternalParameters.ParameterModifier): Do some null
2927 checking and return sane values.
2929 * class.cs (Method.Define): If we are a PInvoke method, ensure
2930 that we are static and extern. Report error # 601
2932 * ../errors/cs0601.cs : Add test case for the above error.
2934 2002-04-07 Ravi Pratap <ravi@ximian.com>
2936 * rootcontext.cs (attribute_types): We need to keep type of
2937 all attribute types separately and emit code for them first.
2939 (RegisterAttribute) : Implement.
2941 * class.cs (DefineType): Check if the current Type is a custom
2942 attribute type and register it accordingly.
2944 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
2945 adding the first attribute twice and rename to
2947 (SetGlobalAttributes): this.
2949 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
2952 * attribute.cs (ApplyAttributes): Take an additional argument telling us
2953 if we are processing global arguments. Hmm, I am unsure of this.
2955 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2957 * expression.cs: added static array of strings to avoid calling
2958 Enum.ToString () for Operator in Binary. Significant recover of
2961 2002-04-10 Miguel de Icaza <miguel@ximian.com>
2963 * class.cs (FindMembers): Allow the Builders of the various
2964 members to be null. If they are skip them. This only happens
2965 during the PInvoke declaration.
2967 2002-04-09 Miguel de Icaza <miguel@ximian.com>
2969 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
2970 failure, so we do not keep going afterwards.
2972 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
2973 wanted to pass `false' as the `is_delegate' argument. If this is
2974 the case, why not use delegate_type == null to mean `is_delegate =
2975 false' and anything else as is_delegate = true.
2977 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
2979 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
2980 code for the section, not the beginning of the tests.
2982 2002-04-08 Miguel de Icaza <miguel@ximian.com>
2984 * cfold.cs: Handle operator + (Enum x, Underlying x)
2986 * expression.cs (Binary): same. Warn about errors where we have
2987 Enum/Enum in operator + as well.
2989 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
2992 - added support for switch(bool)
2993 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
2994 - add TableSwitchEmit() to handle table-based switch statements
2996 2002-04-05 Ravi Pratap <ravi@ximian.com>
2998 * expression.cs (Invocation.OverloadResolve): Factor out code which
2999 does parameter compatibility checking with arguments so that we can
3000 re-use the code even from Delegate.VerifyApplicability
3002 (VerifyArgumentsCompat): Move above code here.
3004 * delegate.cs (VerifyApplicability): Get rid of duplicate code
3005 and instead make a call to the above method.
3007 2002-03-31 Ravi Pratap <ravi@ximian.com>
3009 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
3010 We use it to keep track of classes which are attribute types.
3012 2002-04-02 Miguel de Icaza <miguel@ximian.com>
3014 * delegate.cs (Delegate.Define): Correctly define the types in the
3015 presence of fixed and array parameters.
3017 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
3020 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
3021 include NonPublic after the first iteration.
3023 * class.cs (Indexer.CheckBase): Only check if both parents are
3026 * cs-parser.jay (accessor_body): If empty, set to null.
3028 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
3029 same code path here to resolve constants names that we did have in
3030 MemberAccess.DoResolve. There is too much code duplicated here.
3032 2002-04-01 Miguel de Icaza <miguel@ximian.com>
3034 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
3036 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
3039 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
3040 tokens, numbers and strings.
3042 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
3045 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
3046 asyncronous parameters and the regular parameters.
3048 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
3049 specify the target directory.
3051 * expression.cs: (This.DoResolve): Simplify
3052 (As.Emit): Optimize, do not generate IsInst if the expression is
3053 always of the given type.
3055 (Is.DoResolve): Bug fix, we were reporting both always/never for
3058 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
3059 creating too many unnecessary arrays.
3061 2002-03-31 Miguel de Icaza <miguel@ximian.com>
3063 * class.cs (EmitFieldInitializer): Use Assign expression to assign
3064 fields instead of rolling our own initializer. Takes care of all
3065 implicit conversions, and drops unnecessary static checks/argument.
3067 2002-03-31 Dick Porter <dick@ximian.com>
3069 * driver.cs: use the GetDirectories() return values properly, and
3070 use "/" as path separator.
3072 2002-03-30 Miguel de Icaza <miguel@ximian.com>
3074 * expression.cs (Unary): Optimize - - expr into expr.
3075 (Binary): Optimize a + (-b) into a -b.
3077 * codegen.cs (CodeGen): Made all methods static.
3079 2002-03-29 Miguel de Icaza <miguel@ximian.com>
3083 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
3084 TypeBuilder property.
3086 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
3089 * tree.cs: Removed the various RecordXXXX, and replaced with a
3090 single RecordDecl. Removed all the accessor methods, and just
3091 left a single access point Type
3093 * enum.cs: Rename DefineEnum to DefineType.
3095 * decl.cs: New abstract method `DefineType' used to unify the
3096 Defines for Enumerations, Interfaces, TypeContainers and
3099 (FindType): Moved LookupInterfaceOrClass here. Moved the
3100 LookupBaseClasses method that used to live in class.cs and
3101 interface.cs here, and renamed to FindType.
3103 * delegate.cs: Implement DefineType. Take advantage of the
3104 refactored pattern for locating the parent builder without taking
3105 the parent_builder argument (which we know does not work if we are
3106 nested, and triggering a toplevel definition).
3108 2002-03-28 Miguel de Icaza <miguel@ximian.com>
3110 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
3111 accessibility of a member has changed during override and report
3114 * class.cs (Method.Define, Property.Define): Only complain on
3115 overrides if the method is private, any other accessibility is
3116 fine (and since we just checked the permission is the same, we are
3119 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
3120 and elif are processed always. The other pre-processing
3121 directives are only processed if we are "taking" the path
3123 2002-03-29 Martin Baulig <martin@gnome.org>
3125 * class.cs (Method.Emit): Only emit symbolic debugging info if the
3126 current location is not Null.
3128 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
3129 a separate method so we can profile it.
3131 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
3132 `span.Seconds' are just seconds, but no minutes or hours.
3133 (MainDriver): Profile the CodeGen.SaveSymbols calls.
3135 2002-03-28 Miguel de Icaza <miguel@ximian.com>
3137 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
3138 Remove the gratuitous set of Final:
3140 // If an interface implementation, then we can set Final.
3141 if (((flags & MethodAttributes.Abstract) == 0) &&
3142 implementing.DeclaringType.IsInterface)
3143 flags |= MethodAttributes.Final;
3145 I do not know what I was smoking when I used that.
3148 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
3149 step into fixing the name resolution issues for delegates and
3150 unifying the toplevel name resolution.
3152 2002-03-28 Martin Baulig <martin@gnome.org>
3154 * class.cs (Method.Emit): If we have a symbol writer, call its
3155 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
3156 tell it about the current method.
3158 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
3159 writer that we're going to emit the first byte of IL code for a new
3160 statement (a new source line).
3161 (EmitContext.EmitTopBlock): If we have a symbol writer, call
3162 EmitContext.Mark() before emitting any code.
3164 * location.cs (SymbolDocument): Return null when we're Null.
3166 * statement.cs (Statement): Moved the `Location loc' variable here.
3167 (Statement.EmitBoolExpression): If we have a symbol writer, call
3168 ec.Mark() before emitting any code to tell it that we're at the
3169 beginning of a new statement.
3170 (StatementExpression): Added `Location' argument to the constructor.
3171 (Block): Added public readonly variable `StartLocation' and public
3172 variable `EndLocation'. The latter is to be set using SetEndLocation().
3173 (Block): Added constructor which takes a start and end location.
3174 (Block.SetEndLocation): New method. This sets the end location.
3175 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
3176 local variables we create.
3177 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
3178 each statement and do also mark the begin and end of the block.
3180 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
3181 tell it the current lexer.Location, use Location.Null for the end of the
3183 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
3184 current block, set its end location using SetEndLocation().
3185 (statement_expression): StatementExpression constructor now takes the
3186 lexer.Location as additional argument.
3187 (for_statement, declare_local_variables): Likewise.
3188 (declare_local_variables): When creating a new implicit block, use the
3189 new Block constructor and pass it the lexer.Location.
3191 2002-03-28 Miguel de Icaza <miguel@ximian.com>
3193 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
3194 members also on the parent interfaces recursively.
3196 2002-03-27 Miguel de Icaza <miguel@ximian.com>
3198 * report.cs: Use new formats, since Gonzalo finished the missing
3201 * expression.cs (Binary.ResolveOperator): added missing operator|
3202 operator& and operator^ for bool/bool.
3204 * cs-parser.jay: CheckDef now takes a Location argument that is
3205 used to report errors more precisly (instead of reporting the end
3206 of a definition, we try to track something which is a lot closer
3207 to the source of the problem).
3209 * cs-tokenizer.cs: Track global token use, so we can properly flag
3210 the use of #define/#undef after the first token has been seen.
3212 Also, rename the reportXXXX to Error_DescriptiveName
3214 * decl.cs (DeclSpace.IsTopLevel): Move property here from
3215 TypeContainer, so that Enum and Interface can use this too.
3217 * class.cs (TypeContainer.LookupInterfaceOrClass,
3218 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
3219 `builder' argument. Typically this was used to pass the parent
3220 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
3223 The problem is that a nested class could trigger the definition of
3224 a toplevel class, and the builder would be obviously wrong in that
3227 So we drop this argument, and we compute dynamically the
3228 TypeBuilder/ModuleBuilder (the correct information was available
3229 to us anyways from DeclSpace.Parent)
3231 * interface.cs (Interface.DefineInterface): Drop builder
3232 parameter cleanup like class.cs
3234 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
3237 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
3240 (Try.Emit): Propagate the returns value from the statement.
3242 (Return.Emit): Even if we are leavning
3244 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
3246 * modifiers.cs: Fix the computation of MethodAttributes flags.
3248 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
3250 * driver.cs: allow compilation of files that start with '/'.
3251 Add a default case when checking the argument of --target.
3253 2002-03-25 Miguel de Icaza <miguel@ximian.com>
3255 * interface.cs: Implement the same search algorithm for types in
3258 * delegate.cs: Do not allow multiple definition.
3260 * Recovered ChangeLog that got accidentally amputated
3262 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
3264 * rootcontext.cs: Load manually enum to allow core classes to
3265 contain enumerations.
3267 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
3268 Update to new static methods in TypeManager.
3270 * typemanager.cs (GetMethod, GetConstructor): Use our
3271 implementation of FindMembers to find the members, since during
3272 corlib compilation, the types are TypeBuilders and GetMethod and
3273 GetConstructor do not work.
3275 Make all methods in TypeManager static.
3277 (InitCodeHelpers): Split the functionality from
3278 the InitCodeTypes function.
3280 * driver.cs: Call InitCodeHelpers after we have populated the
3283 * cs-parser.jay (delegate_declaration): we did not used to compute
3284 the delegate name correctly for void delegates.
3286 2002-03-24 Miguel de Icaza <miguel@ximian.com>
3288 * rootcontext.cs (RootContext): Init the interface_resolve_order
3289 and type_container_resolve_order always.
3291 (ResolveCore, BootstrapCorlib_ResolveClass,
3292 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
3293 compiler when compiling with --nostdlib
3295 * class.cs (TypeContainer.DefineType): Check that our parent is
3296 not null. This test is most important when we are bootstraping
3299 * codegen.cs: Split out the symbol writing code.
3301 2002-03-25 Martin Baulig <martin@gnome.org>
3303 * driver.cs (-g): Made -g an alias for --debug.
3305 2002-03-24 Martin Baulig <martin@gnome.org>
3307 * codegen.cs (SymbolWriter): New public variable. Returns the
3308 current symbol writer.
3309 (CodeGen): Added `bool want_debugging_support' argument to the
3310 constructor. If true, tell the ModuleBuild that we want debugging
3311 support and ask it for the ISymbolWriter.
3312 (Save): If we have a symbol writer, call it's Close() method after
3313 saving the assembly.
3315 * driver.c (--debug): New command line argument to create a
3316 debugger information file.
3318 * location.cs (SymbolDocument): New public property. Returns an
3319 ISymbolDocumentWriter object for the current source file or null
3320 if we don't have a symbol writer.
3322 2002-03-21 Miguel de Icaza <miguel@ximian.com>
3324 * driver.cs (LoadAssembly): Correctly return when all the paths
3325 have been tried and not before.
3327 * statement.cs (Switch.Emit): return the actual coverage for this
3328 statement (returns/not-returns)
3330 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
3331 switch of the statement if we are the last switch section. That
3332 kills two problems: try/catch problems (we used to emit an empty
3333 nop at the end) and switch statements where all branches would
3336 2002-03-19 Miguel de Icaza <miguel@ximian.com>
3338 * driver.cs: Add default assemblies (the equivalent to the
3339 Microsoft CSC.RSP file)
3341 * cs-tokenizer.cs: When updating `cols and setting it to zero,
3342 also update tokens_seen and set it to false.
3344 * driver.cs: Implement --recurse for Mike.
3346 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
3347 correctly splitting out the paths.
3349 2002-03-18 Miguel de Icaza <miguel@ximian.com>
3351 * interface.cs (Interface.PopulateProperty): Instead of using
3352 `parent' as the declaration space for the set parameters, use
3355 * support.cs (InternalParameters): InternalParameters constructor
3356 takes a DeclSpace instead of a TypeContainer.
3358 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
3359 types are being initialized, load the address of it before calling
3362 (New): Provide a mechanism to disable the generation of local
3363 value type temporaries when the caller will be providing us with
3364 an address to store it.
3366 (ArrayCreation.EmitDynamicInitializers): Use it.
3368 2002-03-17 Miguel de Icaza <miguel@ximian.com>
3370 * expression.cs (Invocation.EmitArguments): Only probe for array
3371 property if there is more than one argument. Sorry about that.
3373 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
3376 * class.cs (Method.LabelParameters): Fix incorrect code path that
3377 prevented the `ParamArrayAttribute' from being applied to the
3380 2002-03-16 Miguel de Icaza <miguel@ximian.com>
3382 * support.cs (ReflectionParameters): Correctly compute whether the
3383 last argument is a params array. Fixes the problem with
3386 * typemanager.cs: Make the assemblies array always be non-null
3387 (empty, but non-null)
3389 * tree.cs (RecordDecl): New function that abstracts the recording
3390 of names. This reports error 101, and provides a pointer to the
3391 previous declaration. Fixes a crash in the compiler.
3393 * cs-parser.jay (constructor_declaration): Update to new grammar,
3394 and provide a constructor_body that can be empty.
3396 2002-03-15 Miguel de Icaza <miguel@ximian.com>
3398 * driver.cs: Add support for --resources.
3400 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
3401 Make all types for the various array helper methods be integer.
3403 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
3404 CheckState to ConvCast.
3406 (ConvCast): Now it takes a `checked' state argument, to avoid
3407 depending on the emit context for the conversion, and just using
3408 the resolve time setting.
3410 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
3411 instead of Invocation.EmitArguments. We do not emit the original
3412 arguments, instead we emit those which have been converted to
3413 unsigned int expressions.
3415 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
3417 * codegen.cs: ditto.
3419 * expression.cs (LocalVariableReference): Drop the use of the
3420 Store function that depended on the variable index.
3422 * statement.cs (VariableInfo): Drop the `Idx' property from this
3423 class, as this is not taking into account the indexes for
3424 temporaries tat we generate during the execution, getting the
3427 * class.cs: First emit class initializers, then call the parent
3430 * expression.cs (Binary): Fix opcode emision.
3431 (UnaryMutator.EmitCode): Support checked code generation
3433 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
3434 matches for events for both the Static and Instance scans,
3435 pointing to the same element. Fix that.
3437 2002-03-14 Miguel de Icaza <miguel@ximian.com>
3439 * rootcontext.cs (ResolveTree): Always set the
3440 interface_resolve_order, because nested interfaces will be calling
3443 * class.cs (GetInterfaceOrClass): Track the same resolution
3444 process used by TypeManager.LookupType. This fixes the nested
3445 type lookups in class declarations (separate path from
3448 (TypeContainer.DefineType): Also define nested interfaces.
3449 (TypeContainer.RegisterOrder): New public function used to
3450 register the order in which child interfaces need to be closed.
3452 Nested interfaces need to be closed after their parents have been
3455 * interface.cs (InterfaceAttr): Put all the logic for computing
3456 the interface attribute here.
3458 (DefineInterface): Register our interface order with the
3459 RootContext or with the TypeContainer depending on the case.
3461 2002-03-12 Miguel de Icaza <miguel@ximian.com>
3463 * cs-parser.jay: rework foreach statement to work with the new
3464 changes to the policy on SimpleNames.
3466 * report.cs: support Stacktrace on warnings as well.
3468 * makefile: drop --unsafe and /unsafe from the compile.
3470 2002-03-13 Ravi Pratap <ravi@ximian.com>
3472 * ecore.cs (StandardConversionExists): Modify to take an Expression
3473 as the first parameter. Ensure we do null -> reference type conversion
3476 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
3477 temporary Expression objects.
3479 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
3481 * interface.cs: workaround bug in method overloading resolution
3482 (there is already a bugzilla bug for it).
3484 2002-03-12 Miguel de Icaza <miguel@ximian.com>
3486 We could also solve this problem by having a separate path for
3487 performing type lookups, instead of DoResolve, we could have a
3488 ResolveType entry point, and only participating pieces of the
3489 production (simplename, deref, array) would implement this.
3491 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
3492 signal SimpleName to only resolve type names and not attempt to
3493 resolve anything else.
3495 * expression.cs (Cast): Set the flag.
3497 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
3499 * class.cs: Only report 108 if there is no `new' modifier.
3501 * cs-parser.jay: rework foreach statement to work with the new
3502 changes to the policy on SimpleNames.
3504 * report.cs: support Stacktrace on warnings as well.
3506 * makefile: drop --unsafe and /unsafe from the compile.
3508 2002-03-11 Miguel de Icaza <miguel@ximian.com>
3510 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
3511 lookups here, instead of doing that at parse time. This means
3512 that our grammar will not introduce `LocalVariableReferences' as
3513 expressions at this point. That solves the problem of code like
3521 This is only half the fix. The full fix requires parameters to
3522 also be handled in this way.
3524 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
3525 makes the use more obvious of the DeclSpace. The
3526 ec.TypeContainer.TypeBuilder is now only used to pull the
3529 My theory is that I can get rid of the TypeBuilder completely from
3530 the EmitContext, and have typecasts where it is used (from
3531 DeclSpace to where it matters).
3533 The only pending problem is that the code that implements Aliases
3534 is on TypeContainer, and probably should go in DeclSpace.
3536 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
3537 lookups here, instead of doing that at parse time. This means
3538 that our grammar will not introduce `LocalVariableReferences' as
3539 expressions at this point. That solves the problem of code like
3547 This is only half the fix. The full fix requires parameters to
3548 also be handled in this way.
3550 * class.cs (Property.DefineMethod): When implementing an interface
3551 method, set newslot, when implementing an abstract method, do not
3552 set the flag (before we tried never setting it, or always setting
3553 it, which is the difference).
3554 (Indexer.DefineMethod): same.
3555 (Method.DefineMethod): same.
3557 * ecore.cs: Only set the status used flag if we get back a Field.
3559 * attribute.cs: Temporary hack, so Paolo can keep working.
3561 2002-03-08 Ravi Pratap <ravi@ximian.com>
3563 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
3564 the unmanaged type in the case we have a MarshalAs attribute.
3566 (Resolve): Handle the case when we are parsing the special MarshalAs
3567 attribute [we need to store the unmanaged type to use later]
3569 * typemanager.cs (marshal_as_attr_type): Built in type for the
3570 MarshalAs Attribute.
3572 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
3573 on parameters and accordingly set the marshalling info.
3575 2002-03-09 Miguel de Icaza <miguel@ximian.com>
3577 * class.cs: Optimizing slightly by removing redundant code after
3578 we switched to the `NoTypes' return value.
3579 (Property.DefineMethod): use NoTypes here too.
3581 This fixes the bug I introduced in my last batch of changes.
3583 2002-03-05 Ravi Pratap <ravi@ximian.com>
3585 * tree.cs (RecordEnum): Add. We now keep track of enums too.
3587 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
3588 Enums since those are types too.
3590 * cs-parser.jay (enum_declaration): Record enums as we parse them.
3592 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
3593 thanks to a call during the lookup process.
3595 2002-03-07 Miguel de Icaza <miguel@ximian.com>
3597 * statement.cs (Foreach): Lots of work to accomodate a particular
3598 kind of foreach statement that I had not kept in mind. It is
3599 possible to have foreachs on classes that provide a GetEnumerator
3600 method that return objects that implement the "pattern" for using
3601 a foreach, there is no need to support GetEnumerator
3604 This is needed to compile nant.
3606 * decl.cs: Only report 114 if the member is not `Finalize' and if
3607 the warning level is at least 2.
3609 * class.cs: Moved the compare function from Method to
3612 (MethodSignature.InheritableMemberSignatureCompare): Add new
3613 filter function that is used to extract inheritable methods from a
3616 (Method.Define): Use the new `inheritable_method_signature_filter'
3619 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
3622 2002-03-06 Miguel de Icaza <miguel@ximian.com>
3624 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
3626 * cs-parser.jay: Add opt_semicolon to the interface declaration.
3628 * expression.cs: Pass location information to

3636 * expression.cs (Is.DoResolve): If either side of the `is' is an
3637 interface, do not flag the warning.

3642 * report.cs: Allow for --fatal to be used with --probe.
3644 * typemanager.cs (NoTypes): Move the definition for the empty Type
3647 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
3649 (TypeContainer.DefineProxy): New function used to proxy to parent
3650 implementations when implementing interfaces.
3651 (TypeContainer.ParentImplements): used to lookup if our parent
3652 implements a public function that is required by an interface.
3653 (TypeContainer.VerifyPendingMethods): Hook this up.
3655 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
3656 `modules' and `assemblies' arraylists into arrays. We only grow
3657 these are the very early start up of the program, so this improves
3658 the speedof LookupType (nicely measured).
3660 * expression.cs (MakeByteBlob): Replaced unsafe code with
3661 BitConverter, as suggested by Paolo.
3663 * cfold.cs (ConstantFold.Binary): Special case: perform constant
3664 folding of string concatenation, but if either side is a string,
3665 and the other is not, then return null, and let the runtime use
3666 the concatenation on the string plus the object (using
3669 2002-03-04 Miguel de Icaza <miguel@ximian.com>
3671 Constant Folding has been implemented now.

3678 perform implict and explicit conversions.
3680 * ecore.cs (EnumConstant): Implement the new functions to perform

3684 own separate setting that can not be turned off from the command
3685 line using --unchecked or --checked and is only controlled using
3686 the checked/unchecked statements and expressions. This setting is
3687 used by the constant folder to flag errors.
3689 * expression.cs (CheckedExpr, UncheckedExpr): Set the
3690 ConstantCheckState as well.
3692 During Resolve, they also have to flag the state, because the
3693 constant folder runs completely in the Resolve phase.
3695 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
3698 2002-03-01 Miguel de Icaza <miguel@ximian.com>
3700 * cfold.cs: New file, this file contains the constant folder.
3702 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
3703 argument to track whether we are using the resulting address to
3704 load or store a value and provide better error messages.
3706 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
3707 new AddressOf arguments.
3709 * statement.cs (Foreach.EmitCollectionForeach): Update

3724 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
3727 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
3728 essentially like methods and apply attributes like MethodImplOptions to them too.
3730 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
3733 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
3734 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
3737 * Update code everywhere accordingly.
3739 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
3741 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
3743 2002-02-28 Ravi Pratap <ravi@ximian.com>
3745 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
3746 try performing lookups against those instead of jumping straight into using
3747 the 'using' clauses.
3749 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
3751 (LookupType): Perform lookups in implicit parents too.
3753 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
3754 sequence as RootContext.LookupType.
3756 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
3757 the various cases of namespace lookups into this method.
3759 2002-03-01 Miguel de Icaza <miguel@ximian.com>
3761 * cs-parser.jay: Add support for [Attribute ()] (empty arguments

3779 2002-02-26 Miguel de Icaza <miguel@ximian.com>
3781 * expression.cs: Special case the `null' object when trying to
3782 auto-compute the type, as anything can be explicitly converted to
3785 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
3786 spotting this Paolo.
3788 (Expression.ImplicitNumericConversion): Perform comparissions of
3789 the type using the underlying type in the case of an enumeration
3790 rather than using the enumeration type for the compare.
3792 Cope with the underlying == type case, which is not possible to
3795 (Expression.ConvertNumericExplicit): Perform comparissions of
3796 the type using the underlying type in the case of an enumeration
3797 rather than using the enumeration type for the compare.
3799 * driver.cs: If the user does not supply an extension, assume .exe
3801 * cs-parser.jay (if_statement): Rewrote so that we can track the
3802 location for the if statement.
3804 * expression.cs (Binary.ConstantFold): Only concat strings when
3805 the operation is "+", not everything ;-)

3809 (If, While, Do): Track location.
3811 * expression.cs (Binary.ResolveOperator): In the object + string

3814 2002-02-25 Ravi Pratap <ravi@ximian.com>
3816 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
3817 Location arguments. Ensure we use RootContext.LookupType to do our work
3818 and not try to do a direct Type.GetType and ModuleBuilder.GetType
3820 * interface.cs (PopulateMethod): Handle the type of the parameter being
3823 * expression.cs (Invocation.BetterFunction): Handle the case when we
3824 have a params method with no fixed arguments and a call is made with no

3838 (GetParameterByName): Fix bug where we were not looking up array
3839 paramters if they were the only present (thanks Paolo!).
3840 (GetParameterInfo): We only have an empty set of types if both
3841 fixed and array are set to null.
3842 (GetParameterInfo-idx): Handle FixedParameter == null
3844 * cs-parser.jay: Handle the case where there is no catch

3867 * expression.cs (Binary.ResolveOperator): Remove redundant
3868 MemberLookup pn parent type.
3869 Optimize union call, we do not need a union if the types are the same.
3870 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
3873 Specialize the use of MemberLookup everywhere, instead of using
3874 the default settings.
3876 (StackAlloc): Implement stackalloc keyword.
3878 * cs-parser.jay: Add rule to parse stackalloc.
3880 * driver.cs: Handle /h, /help, /?

3899 are missing one more case before we are done.
3901 * expression.cs (Indirection): Implement EmitAssign and set the
3902 ExprClass to Variable. This allows pointer dereferences to be
3903 treated as variables, and to have values assigned to them.
3905 * ecore.cs (Expression.StoreFromPtr): New utility function to
3906 store values dereferencing.
3908 2002-02-20 Ravi Pratap <ravi@ximian.com>

3915 the parent implementation is sealed.
3917 * ../errors/cs0239.cs : Add.
3919 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
3921 * typemanager.cs (unverifiable_code_type): Corresponds to
3922 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
3923 which have unsafe code in them.
3925 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an

3955 2002-02-14 Miguel de Icaza <miguel@ximian.com>
3957 * class.cs (Property.Define, Method.Define): Remove newslot when
3960 * modifiers.cs: My use of NewSlot when `Abstract' was set was
3961 wrong. NewSlot should only be used if the `new' keyword is present.
3963 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
3964 locating our system dir. Sorry about this.
3966 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3968 * driver.cs (GetSystemDir): Compute correctly the location of our
3969 system assemblies. I was using the compiler directory instead of
3970 the library directory.
3972 2002-02-13 Ravi Pratap <ravi@ximian.com>
3974 * expression.cs (BetterFunction): Put back in what Miguel commented out
3975 since it is the correct fix. The problem is elsewhere ;-)
3977 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
3978 parameters of the parms method are themselves compatible or not !
3980 (StandardConversionExists): Fix very dangerous bug where we were forgetting
3981 to check that a class implements an interface before saying that an implicit
3982 conversion was allowed. Use ImplementsInterface to do the checking.
3984 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3986 * class.cs (Method.Define): Track whether we are an explicit
3987 implementation or not. And only call DefineMethodOverride if we
3988 are an explicit implementation.

3998 2002-01-29 Miguel de Icaza <miguel@ximian.com>
4000 * support.cs (Pair): Remove un-needed method. I figured why I was
4001 getting the error in cs-parser.jay, the variable in a foreach loop
4002 is readonly, and the compiler does not really treat this as a variable.
4004 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
4005 instead of EQUALS in grammar.
4007 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
4009 * expression.cs (Unary.DoResolve): Check whether the argument is
4012 2002-01-28 Miguel de Icaza <miguel@ximian.com>
4014 * support.cs: Api for Pair to set a value. Despite the fact that

4016 code that accesses the field if the variable is part of a foreach
4019 * statement.cs (Fixed): Begin implementation of the fixed
4022 (Block.AddVariable): Return the VariableInfo on success and null
4023 on failure instead of true/false.

4074 Statement.EmitBoolExpression): Add support to Do and While to
4075 propagate infinite loop as `I do return' semantics.
4077 Improve the For case to also test for boolean constants.
4079 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
4080 to the list of attributes we can add.
4082 Remove `EmitContext' argument.

4086 (MethodCore.LabelParameters): Move here the core of labeling
4089 * support.cs (ReflectionParameters.ParameterModifier,
4090 InternalParameters.ParameterModifier): Use IsByRef on the type and
4091 only return the OUT bit for these parameters instead of in/out/ref
4094 This is because I miss-understood things. The ParameterInfo.IsIn
4095 and IsOut represent whether the parameter has the [In] and [Out]

4116 * driver.cs: Compute dynamically the system directory.
4118 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
4119 Slower, but more generally useful. Used by the abstract
4120 registering implementation.
4122 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
4123 the rules for the special rule on Type/instances. First check if
4124 we have the same name, and if so, try that special static path
4125 rather than the instance path.
4127 2002-01-18 Miguel de Icaza <miguel@ximian.com>

4147 conversions when we neecd to compute it for conditional

4167 (PopulateProperty): ditto.
4168 (PopulateIndexer): ditto.
4170 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be

4182 code, as the constant resolution moved.
4184 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
4185 the metadata, so we can flag error 133.

4188 pointer is being declared in an unsafe context.
4190 2002-01-16 Miguel de Icaza <miguel@ximian.com>
4192 * modifiers.cs (Modifiers.Check): Require a Location argument.
4193 Report error 227 for Unsafe use.
4195 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
4197 * statement.cs (For.Emit): If the test is null, then report that
4198 we do `return', as we wont reach anything afterwards.
4200 (Switch.SwitchGoverningType): Track the expression that matched
4203 * driver.cs: Allow negative numbers as an error code to flag.
4205 * cs-parser.jay: Handle 1551.

4229 * typemanager.cs (IsPointerType): Utility method which we are going
4232 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
4233 the object type, so we take care of that.
4235 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
4237 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
4238 added to non-params parameters :-)

4299 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
4300 this routine and will wrap the call in a try/catch block. Deal
4303 2002-01-11 Miguel de Icaza <miguel@ximian.com>
4305 * ecore.cs (Expression.MemberLookup): instead of taking a
4306 parameter `same_type' that was used to tell whether we could
4307 access private members we compute our containing type from the
4310 (FieldExpr): Added partial support for volatile fields. This does
4311 not work for volatile fields exposed from assemblies, as I can not
4312 figure out how to extract the modreq from it.
4314 Updated all the source files to use this.
4316 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
4317 because it is referenced by MemberLookup very often.
4319 2002-01-09 Ravi Pratap <ravi@ximian.com>
4321 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
4322 TypeBuilder.GetCustomAttributes to retrieve what we need.
4324 Get rid of redundant default_member_attr_type as this is the same as
4325 default_member_type which already exists.
4327 * interface.cs, attribute.cs : Update accordingly.
4329 2002-01-08 Miguel de Icaza <miguel@ximian.com>
4331 * typemanager.cs: Enable IndexerPropertyName again. It does not
4332 work for TYpeBuilders though. Ravi, can you please fix this?
4334 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
4336 * expression.cs (Argument.Emit): Handle the case of ref objects
4337 being passed to ref functions;
4339 (ParameterReference.EmitLoad): Loads the content of the pointer
4340 without dereferencing.
4342 2002-01-07 Miguel de Icaza <miguel@ximian.com>
4344 * cs-tokenizer.cs: Implemented the pre-processing expressions.
4346 2002-01-08 Ravi Pratap <ravi@ximian.com>
4348 * class.cs (Indexer.DefineMethod): Incorporate the interface
4349 type in the name of the method if we are doing explicit interface
4352 * expression.cs (ConversionExists): Remove as it is completely obsolete.
4354 (BetterConversion): Fix extremely trivial bug where we were referring to
4355 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
4358 * ../errors/bug16.cs : Add although we have fixed it.
4360 2002-01-07 Miguel de Icaza <miguel@ximian.com>
4362 * expression.cs (BaseIndexer): Begin implementation.
4364 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
4366 * cs-parser.jay (indexer_declarator): Use qualified_identifier
4367 production directly to remove a shift/reduce, and implement
4368 explicit interface implementation.
4370 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
4371 after a floating point suffix.
4373 * expression.cs (DoNumericPromotions): Improved the conversion for
4374 uint/uint. If we have a constant, we avoid doing a typecast to a
4377 * class.cs (Indexer): Implement explicit interface implementation
4380 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
4382 * class.cs: make the default instance constructor public and hidebysig.
4384 2001-01-03 Ravi Pratap <ravi@ximian.com>
4386 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
4387 so we can call it from elsewhere.
4389 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
4390 we emit it internally if the class has a defined indexer; otherwise the user
4391 emits it by decorating the class definition with the DefaultMemberAttribute.
4393 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
4394 attribute is not used on a type which defines an indexer.
4396 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
4397 character when we skip whitespace.
4399 * ../errors/cs0646.cs : Add.
4401 2002-01-03 Miguel de Icaza <miguel@ximian.com>
4403 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
4406 * makefile: Add practical target `mcs3.exe' which builds the third
4407 generation compiler.
4409 * expression.cs (New): Fix structures constructor calling.
4411 * class.cs (Property, Method, Indexer): Emit Final flag on the
4412 method if we are an interface implementation and we are not
4415 * ecore.cs (PropertyExpr): New public field `IsBase', tells
4416 whether this property is referencing a `base' method.
4418 * expression.cs (Invocation.EmitCall): take an extra argument:
4419 is_base, this is used to determine whether the `call' or
4420 `callvirt' opcode should be used.
4423 * delegate.cs: update EmitCall.
4425 * class.cs (Method.Define): Set NewSlot for the cases where we are
4426 not implementing an interface method.
4428 (Property.Define): ditto.
4430 2002-01-02 Miguel de Icaza <miguel@ximian.com>
4432 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
4433 'r'. Allows mcs to parse itself fully.
4435 2002-01-02 Ravi Pratap <ravi@ximian.com>
4437 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
4438 of the number of initializers that require the InitializeArray method.
4440 (CheckIndices): Store the Expression in all cases - not the plain value. Also
4441 update the above field where necessary.
4443 (MakeByteBlob): Update accordingly.
4445 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
4448 (EmitDynamicInitializers): Update in accordance with the new optimization.
4450 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
4451 same OpCode applies.
4453 * cs-parser.jay : Fix some glaring errors I introduced.
4455 2002-01-01 Ravi Pratap <ravi@ximian.com>
4457 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
4458 so that we can check for name clashes there too.
4460 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
4461 for interface indexers.
4463 * interfaces.cs (Define): Emit the default member attribute.
4465 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
4466 variable was being referred to while setting the value ;-)
4468 2002-01-01 Miguel de Icaza <miguel@ximian.com>
4470 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
4471 byte-by-byte information when we know the data is zero.
4473 Make the block always a multiple of 4, because
4474 DefineInitializedData has a bug.
4476 * assign.cs: Fix, we should assign from the temporary, not from
4479 * expression.cs (MakeByteBlob): Fix my incorrect code.
4481 2001-12-31 Miguel de Icaza <miguel@ximian.com>
4483 * typemanager.cs (EnumToUnderlying): This function is used to get
4484 the underlying type from an enumeration, because it does not
4487 * constant.cs: Use the I4_S form for values between -128 and 127.
4489 * statement.cs (Block.LookupLabel): Looks up a label.
4490 (Block): Drop support for labeled blocks.
4492 (LabeledStatement): New kind of statement that represents a label
4495 (Goto): Finally implement this bad boy.
4497 * cs-parser.jay: Update to reflect new mechanism to implement
4500 2001-12-30 Miguel de Icaza <miguel@ximian.com>
4502 * codegen.cs (EmitContext.This): a codegen property that keeps the
4503 a single instance of this instead of creating many different this
4506 * delegate.cs (Delegate.DoResolve): Update to use the property;
4508 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
4510 * expression.cs (BaseAccess.DoResolve): Ditto.
4512 2001-12-29 Ravi Pratap <ravi@ximian.com>
4514 * typemanager.cs (methodimpl_attr_type): Add to hold the type
4515 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
4517 (InitCoreTypes): Update accordingly.
4519 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
4520 so we can quickly store the state.
4522 (ApplyAttributes): Set the correct implementation flags
4523 for InternalCall methods.
4525 2001-12-29 Miguel de Icaza <miguel@ximian.com>
4527 * expression.cs (EmitCall): if a method is not virtual, then do
4528 not use callvirt on it.
4530 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
4531 user defined stuff) requires the use of stobj, which takes an
4532 address on the stack instead of an array and an index. So emit
4533 the Ldelema operation for it.
4535 (EmitStoreOpcode): Use stobj for valuetypes.
4537 (UnaryMutator.EmitCode): Use the right 1 value depending on
4538 whether we are dealing with int64/uint64, float or doubles.
4540 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
4541 constructors that I implemented last night.
4543 (Constructor.IsDefault): Fix to work properly for static
4546 * cs-parser.jay (CheckDef): report method signature errors.
4547 Update error number 103 to be 132.
4549 * decl.cs: New AdditionResult enumeration value: MethodExists.
4550 Although we do this check for methods later on in the semantic
4551 analysis, catching repeated default constructors is so easy that
4552 we catch these here.
4554 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
4557 (ParameterReference.EmitAssign, Emit): handle
4560 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
4561 (ArrayAccess.EmitStoreOpcode): ditto.
4563 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
4565 * expression.cs (MakeByteBlob): Complete all the missing types
4566 (uint, short, ushort, byte, sbyte)
4568 * class.cs: Only init instance field initializers on instance
4571 Rename `constructors' to instance_constructors.
4573 (TypeContainer.AddConstructor): Only add constructors to the list
4574 if it is not static.
4576 Make sure that we handle default_static_constructor independently
4577 everywhere where we handle instance_constructors
4579 2001-12-28 Miguel de Icaza <miguel@ximian.com>
4581 * class.cs: Do not lookup or create a base initializer for a
4584 (ConstructorInitializer.Resolve): use the proper type to lookup
4587 * cs-parser.jay: Report error 1585 (modifiers between type and name).
4589 * enum.cs, interface.cs: Remove CloseType, this is taken care by
4592 * decl.cs: CloseType is now an virtual method, the default
4593 implementation just closes this type.
4595 2001-12-28 Ravi Pratap <ravi@ximian.com>
4597 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
4598 to PreserveSig by default. Also emit HideBySig on such methods.
4600 Basically, set the defaults to standard values.
4602 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
4603 argument, if candidate is better, it can't be worse than the best !
4605 (Invocation): Re-write bits to differentiate between methods being
4606 applicable in their expanded form and their normal form - for params
4609 Get rid of use_standard everywhere as only standard conversions are allowed
4610 in overload resolution.
4612 More spec conformance.
4614 2001-12-27 Miguel de Icaza <miguel@ximian.com>
4616 * driver.cs: Add --timestamp, to see where the compiler spends
4619 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
4620 `this' in static code.
4622 (SimpleName.DoResolve): Implement in terms of a helper function
4623 that allows static-references to be passed upstream to
4626 (Expression.ResolveWithSimpleName): Resolve specially simple
4627 names when called by MemberAccess to implement the special
4630 (Expression.ImplicitReferenceConversion): Handle conversions from
4631 Null to reference types before others, as Null's type is
4634 * expression.cs (Invocation.EmitCall): Handle the special case of
4635 calling methods declared on a reference type from a ValueType
4636 (Base classes System.Object and System.Enum)
4638 (MemberAccess.Resolve): Only perform lookups on Enumerations if
4639 the left hand side is a TypeExpr, not on every enumeration.
4641 (Binary.Resolve): If types are reference types, then do a cast to
4642 object on operators != and == of both arguments.
4644 * typemanager.cs (FindMembers): Extract instance and static
4645 members if requested.
4647 * interface.cs (PopulateProperty): Use void_type instead of null
4648 as the return type for the setter method.
4650 (PopulateIndexer): ditto.
4652 2001-12-27 Ravi Pratap <ravi@ximian.com>
4654 * support.cs (ReflectionParameters): Fix minor bug where we
4655 were examining the wrong parameter for the ParamArray attribute.
4657 Cope with requests for the type of the parameter at position
4658 greater than the params parameter's. We now return the element
4659 type of the params array as that makes more sense.
4661 * expression.cs (Invocation.IsParamsMethodApplicable): Update
4662 accordingly as we no longer have to extract the element type
4665 (Invocation.OverloadResolve): Update.
4667 2001-12-27 Miguel de Icaza <miguel@ximian.com>
4669 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
4670 against IEnumerator, test whether the return value is a descendant
4671 of the IEnumerator interface.
4673 * class.cs (Indexer.Define): Use an auxiliary method to implement
4674 the other bits of the method definition. Begin support for
4675 explicit interface implementation.
4677 (Property.DefineMethod): Use TypeManager.void_type instead of null
4678 for an empty return value.
4680 2001-12-26 Miguel de Icaza <miguel@ximian.com>
4682 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
4683 dealing with a FieldExpr which is composed of a FieldBuilder, in
4684 the code path we did extract the constant, but we should have
4685 obtained the underlying value to be able to cast it (otherwise we
4686 end up in an infinite loop, this is what Ravi was running into).
4688 (ArrayCreation.UpdateIndices): Arrays might be empty.
4690 (MemberAccess.ResolveMemberAccess): Add support for section
4691 14.5.4.1 that deals with the special case of E.I when E is a type
4692 and something else, that I can be a reference to a static member.
4694 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
4695 handle a particular array type to create byte blobs, it is just
4696 something we dont generate byteblobs for.
4698 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
4701 * location.cs (Push): remove the key from the hashtable that we
4702 are about to add. This happens for empty files.
4704 * driver.cs: Dispose files after we have parsed them.
4706 (tokenize): new function that only runs the tokenizer on its
4707 input, for speed testing.
4709 2001-12-26 Ravi Pratap <ravi@ximian.com>
4711 * class.cs (Event.Define): Define the private field only if there
4712 are no accessors defined.
4714 * expression.cs (ResolveMemberAccess): If there is no associated
4715 field with the event, that means we have an event defined with its
4716 own accessors and we should flag error cs0070 since transforming
4717 ourselves into a field is not valid in that case.
4719 * ecore.cs (SimpleName.DoResolve): Same as above.
4721 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
4722 and charset to sane values.
4724 2001-12-25 Ravi Pratap <ravi@ximian.com>
4726 * assign.cs (DoResolve): Perform check on events only if they
4727 are being accessed outside the declaring type.
4729 * cs-parser.jay (event_declarations): Update rules to correctly
4730 set the type of the implicit parameter etc.
4732 (add_accessor, remove_accessor): Set current local parameters.
4734 * expression.cs (Binary): For delegate addition and subtraction,
4735 cast the return value from the method into the appropriate delegate
4738 2001-12-24 Ravi Pratap <ravi@ximian.com>
4740 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
4741 of these as the workaround is unnecessary.
4743 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
4744 delegate data - none of that is needed at all.
4746 Re-write bits to extract the instance expression and the delegate method
4749 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
4752 * attribute.cs (ApplyAttributes): New method to take care of common tasks
4753 of attaching attributes instead of duplicating code everywhere.
4755 * everywhere : Update code to do attribute emission using the above method.
4757 2001-12-23 Miguel de Icaza <miguel@ximian.com>
4759 * expression.cs (IsParamsMethodApplicable): if there are not
4760 parameters, return immediately.
4762 * ecore.cs: The 0 literal can be implicity converted to an enum
4765 (SimpleName.DoResolve): First lookup the type, then lookup the
4768 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
4769 want to get its address. If the InstanceExpression is not
4770 addressable, store the result in a temporary variable, then get
4773 * codegen.cs: Only display 219 errors on warning level or above.
4775 * expression.cs (ArrayAccess): Make it implement the
4776 IMemoryLocation interface.
4778 (Binary.DoResolve): handle the operator == (object a, object b)
4779 and operator != (object a, object b) without incurring into a
4780 BoxedCast (because 5 != o should never be performed).
4782 Handle binary enumerator operators.
4784 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
4785 value type, otherwise use Ldelem_ref.
4787 Use precomputed names;
4789 (AddressOf): Implement address of
4791 * cs-parser.jay (labeled_statement): Fix recursive block
4792 addition by reworking the production.
4794 * expression.cs (New.DoEmit): New has a special case:
4796 If we are dealing with a ValueType, we have a few
4797 situations to deal with:
4799 * The target of New is a ValueType variable, that is
4800 easy, we just pass this as the variable reference
4802 * The target of New is being passed as an argument,
4803 to a boxing operation or a function that takes a
4806 In this case, we need to create a temporary variable
4807 that is the argument of New.
4810 2001-12-23 Ravi Pratap <ravi@ximian.com>
4812 * rootcontext.cs (LookupType): Check that current_type is not null before
4813 going about looking at nested types.
4815 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
4816 not implement the IAssignMethod interface any more.
4818 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
4819 where we tranform them into FieldExprs if they are being resolved from within
4822 * ecore.cs (SimpleName.DoResolve): Do the same here.
4824 * assign.cs (DoResolve, Emit): Clean up code considerably.
4826 * ../errors/bug10.cs : Add.
4828 * ../errors/cs0070.cs : Add.
4830 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
4832 * assign.cs : Get rid of EventIsLocal everywhere.
4834 2001-12-23 Miguel de Icaza <miguel@ximian.com>
4836 * ecore.cs (ConvertIntLiteral): finished the implementation.
4838 * statement.cs (SwitchLabel): Convert the value we are using as a
4839 key before looking up the table.
4841 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4843 * codegen.cs (EmitTopBlock): Require a Location argument now.
4845 * cs-parser.jay (constructor_declarator): We need to setup
4846 current_local_parameters before we parse the
4847 opt_constructor_initializer, to allow the variables to be bound
4848 to the constructor arguments.
4850 * rootcontext.cs (LookupType): First lookup nested classes in our
4851 class and our parents before we go looking outside our class.
4853 * expression.cs (ConstantFold): Extract/debox the values at the
4856 * rootcontext.cs (EmitCode): Resolve the constants first before we
4857 resolve the types. This is not really needed, but it helps debugging.
4859 * statement.cs: report location.
4861 * cs-parser.jay: pass location to throw statement.
4863 * driver.cs: Small bug fix.
4865 * report.cs: Updated format to be 4-zero filled digits.
4867 2001-12-22 Ravi Pratap <ravi@ximian.com>
4869 * expression.cs (CheckIndices): Fix minor bug where the wrong
4870 variable was being referred to ;-)
4872 (DoEmit): Do not call EmitStaticInitializers when the
4873 underlying type is System.Object.
4875 2001-12-21 Ravi Pratap <ravi@ximian.com>
4877 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
4878 and do the usual workaround for SRE.
4880 * class.cs (MyEventBuilder.EventType): New member to get at the type
4881 of the event, quickly.
4883 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
4885 * assign.cs (Assign.DoResolve): Handle the case when the target
4886 is an EventExpr and perform the necessary checks.
4888 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
4891 (SimpleName.MemberStaticCheck): Include check for EventExpr.
4893 (EventExpr): Set the type in the constructor itself since we
4894 are meant to be born fully resolved.
4896 (EventExpr.Define): Revert code I wrote earlier.
4898 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
4899 instance expression is null. The instance expression is a This in that case
4900 or a null, depending on whether it is a static method or not.
4902 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
4903 refers to more than one method.
4905 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
4906 and accordingly flag errors.
4908 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4910 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
4912 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4914 * location.cs (ToString): Provide useful rutine.
4916 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4918 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
4919 objects, return the actual integral boxed.
4921 * statement.cs (SwitchLabel): define an ILLabel for each
4924 (Switch.CheckSwitch): If the value is a Literal, extract
4925 the underlying literal.
4927 Also in the unused hashtable we had, add the SwitchLabel so we can
4928 quickly look this value up.
4930 * constant.cs: Implement a bunch of new constants. Rewrite
4931 Literal based on this. Made changes everywhere to adapt to this.
4933 * expression.cs (Expression.MakeByteBlob): Optimize routine by
4934 dereferencing array only once, and also copes with enumrations.
4936 bytes are two bytes wide, not one.
4938 (Cast): Perform constant conversions.
4940 * ecore.cs (TryImplicitIntConversion): Return literals instead of
4941 wrappers to the literals here.
4943 * expression.cs (DoNumericPromotions): long literals can converted
4944 to ulong implicity (this is taken care of elsewhere, but I was
4947 * ecore.cs (Expression.Literalize): Make the return type Literal,
4948 to improve type checking.
4950 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
4952 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4954 * literal.cs: Revert code from ravi that checked the bounds. The
4955 bounds are sane by the definition of the type itself.
4957 * typemanager.cs: Fix implementation of ImplementsInterface. We
4958 need to actually look up in our parent hierarchy for interfaces
4961 * const.cs: Use the underlying type for enumerations
4963 * delegate.cs: Compute the basename for the delegate creation,
4964 that should fix the delegate test case, and restore the correct
4965 Type Lookup semantics in rootcontext
4967 * rootcontext.cs: Revert Ravi's last patch. The correct way of
4968 referencing a nested type with the Reflection API is using the "+"
4971 * cs-parser.jay: Do not require EOF token at the end.
4973 2001-12-20 Ravi Pratap <ravi@ximian.com>
4975 * rootcontext.cs (LookupType): Concatenate type names with
4976 a '.' instead of a '+' The test suite passes again.
4978 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
4979 field of the enumeration.
4981 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
4982 the case when the member is an EventExpr.
4984 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
4985 static has an associated instance expression.
4987 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
4989 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
4991 * class.cs (Event.Define): Register event and perform appropriate checks
4994 We define the Add and Remove methods even if the use provides none because
4995 in that case, we provide default implementations ourselves.
4997 Define a private field of the type of the event. This is done by the CSC compiler
4998 and we should be doing it too ;-)
5000 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
5001 More methods we use in code we generate.
5003 (multicast_delegate_type, delegate_type): Two separate types since the distinction
5006 (InitCoreTypes): Update accordingly for the above.
5008 * class.cs (Event.Emit): Generate code for default accessors that we provide
5010 (EmitDefaultMethod): Do the job in the above.
5012 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
5015 2001-12-20 Miguel de Icaza <miguel@ximian.com>
5017 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
5018 builders even if we were missing one.
5020 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
5021 pass the Basename as our class name instead of the Name. The
5022 basename will be correctly composed for us.
5024 * parameter.cs (Paramters): Now takes a Location argument.
5026 * decl.cs (DeclSpace.LookupType): Removed convenience function and
5027 make all the code call directly LookupType in RootContext and take
5028 this chance to pass the Location information everywhere.
5030 * Everywhere: pass Location information.
5032 2001-12-19 Miguel de Icaza <miguel@ximian.com>
5034 * class.cs (Constructor.Define): Updated way of detecting the
5035 length of the parameters.
5037 (TypeContainer.DefineType): Use basename as the type name for
5040 (TypeContainer.Define): Do not recursively define types here, as
5041 definition is taken care in order by the RootContext.
5043 * tree.cs: Keep track of namespaces in a per-file basis.
5045 * parameter.cs (Parameter.ComputeSignature): Update to use
5048 (Parameters.GetSignature): ditto.
5050 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
5051 instead of a TypeContainer.
5053 (Interface.SemanticAnalysis): Use `this' instead of our parent to
5054 resolve names. Because we need to be resolve in our context, not
5057 * driver.cs: Implement response files.
5059 * class.cs (TypeContainer.DefineType): If we are defined, do not
5062 (Event.Emit): Emit the code for add/remove handlers.
5063 (Event.Define): Save the MethodBuilders for add/remove.
5065 * typemanager.cs: Use pair here too.
5067 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
5068 DictionaryEntry requires the first argument to be non-null.
5070 (enum_declaration): Compute full name for registering the
5073 (delegate_declaration): Instead of using
5074 formal_parameter_list, use opt_formal_parameter_list as the list
5077 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
5078 (EventParsing): New property that controls whether `add' and
5079 `remove' are returned as tokens or identifiers (for events);
5081 2001-12-19 Ravi Pratap <ravi@ximian.com>
5083 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
5084 use MyEventBuilder only and let it wrap the real builder for us.
5086 (MyEventBuilder): Revamp constructor etc.
5088 Implement all operations that we perform on EventBuilder in precisely the same
5091 (FindMembers): Update to use the EventBuilder member.
5093 (Event.Emit): Update accordingly.
5095 2001-12-18 Ravi Pratap <ravi@ximian.com>
5097 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
5098 by calling the appropriate methods.
5100 (GetCustomAttributes): Make stubs as they cannot possibly do anything
5103 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
5105 2001-12-17 Ravi Pratap <ravi@ximian.com>
5107 * delegate.cs (Delegate.Populate): Check that the return type
5108 and various parameters types are indeed accessible.
5110 * class.cs (Constructor.Define): Same here.
5112 (Field.Define): Ditto.
5114 (Event.Define): Ditto.
5116 (Operator.Define): Check that the underlying Method defined itself
5117 correctly - so it's MethodBuilder should not be null.
5119 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
5120 expression happens to be null.
5122 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
5123 members but as of now we don't seem to be able to do anything really useful with it.
5125 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
5126 not the EventBuilder.
5128 2001-12-18 Miguel de Icaza <miguel@ximian.com>
5130 * cs-tokenizer.cs: Add support for defines.
5131 Add support for #if, #elif, #else, #endif
5133 (eval_var): evaluates a variable.
5134 (eval): stubbed for evaluating functions.
5136 * cs-parser.jay: Pass the defines information
5138 * driver.cs: Add --define command line option.
5140 * decl.cs: Move MemberCore here.
5142 Make it the base class for DeclSpace. This allows us to catch and
5143 report 108 and 109 for everything now.
5145 * class.cs (TypeContainer.Define): Extract all the members
5146 before populating and emit the warning 108 (new keyword required
5147 to override) instead of having each member implement this.
5149 (MemberCore.Define): New abstract method, we will be using this in
5150 the warning reporting engine in Populate.
5152 (Operator.Define): Adjust to new MemberCore protocol.
5154 * const.cs (Const): This does not derive from Expression, it is a
5155 temporary object we use to create fields, it is a MemberCore.
5157 * class.cs (Method.Define): Allow the entry point to be in a
5160 * driver.cs: Rewrite the argument handler to clean it up a bit.
5162 * rootcontext.cs: Made it just an auxiliary namespace feature by
5163 making everything static.
5165 * driver.cs: Adapt code to use RootContext type name instead of
5168 * delegate.cs: Remove RootContext argument.
5170 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
5173 * class.cs (Event.Define): The lookup can fail.
5175 * cs-tokenizer.cs: Begin implementation of pre-procesor.
5177 * expression.cs: Resolve the this instance before invoking the code.
5179 2001-12-17 Miguel de Icaza <miguel@ximian.com>
5181 * cs-parser.jay: Add a production in element_access that allows
5182 the thing to become a "type" reference. This way we can parse
5183 things like "(string [])" as a type.
5185 Note that this still does not handle the more complex rules of
5189 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
5191 * ecore.cs: (CopyNewMethods): new utility function used to
5192 assemble the list of methods from running FindMembers.
5194 (MemberLookup): Rework FindMembers so that
5196 2001-12-16 Miguel de Icaza <miguel@ximian.com>
5198 * class.cs (TypeContainer): Remove Delegates who fail to be
5201 * delegate.cs (Populate): Verify that we dont get null return
5202 values. TODO: Check for AsAccessible.
5204 * cs-parser.jay: Use basename to emit error 574 (destructor should
5205 have the same name as container class), not the full name.
5207 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
5208 possible representation.
5210 Also implements integer type suffixes U and L.
5212 2001-12-15 Miguel de Icaza <miguel@ximian.com>
5214 * expression.cs (ArrayCreation.DoResolve): We need to do the
5215 argument resolution *always*.
5217 * decl.cs: Make this hold the namespace. Hold the root context as
5219 (LookupType): Move here.
5221 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
5223 * location.cs (Row, Name): Fixed the code, it was always returning
5224 references to the first file.
5226 * interface.cs: Register properties defined through interfaces.
5228 * driver.cs: Add support for globbing on the command line
5230 * class.cs (Field): Make it derive from MemberCore as well.
5233 2001-12-15 Ravi Pratap <ravi@ximian.com>
5235 * class.cs (Event::Define): Check that the type of the event is a delegate
5236 type else flag error #66.
5238 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
5241 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
5242 values of EntryPoint, CharSet etc etc.
5244 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
5246 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
5247 be null and we should ignore this. I am not sure if this is really clean. Apparently,
5248 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
5249 which needs this to do its work.
5251 * ../errors/cs0066.cs : Add.
5253 2001-12-14 Miguel de Icaza <miguel@ximian.com>
5255 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
5258 * class.cs: (MethodSignature.MethodSignature): Removed hack that
5259 clears out the parameters field.
5260 (MemberSignatureCompare): Cleanup
5262 (MemberCore): New base class used to share code between MethodCore
5265 (RegisterRequiredImplementations) BindingFlags.Public requires
5266 either BindingFlags.Instace or Static. Use instance here.
5268 (Property): Refactored code to cope better with the full spec.
5270 * parameter.cs (GetParameterInfo): Return an empty array instead
5273 * class.cs (Property): Abstract or extern properties have no bodies.
5275 * parameter.cs (GetParameterInfo): return a zero-sized array.
5277 * class.cs (TypeContainer.MethodModifiersValid): Move all the
5278 method modifier validation to the typecontainer so we can reuse
5281 (MethodCore.ParameterTypes): return an empty sized array of types.
5283 (Property.Define): Test property modifier validity.
5285 Add tests for sealed/override too.
5287 (Method.Emit): abstract or extern methods have no bodies.
5289 2001-12-14 Ravi Pratap <ravi@ximian.com>
5291 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
5294 (Method::Define, ::Emit): Modify accordingly.
5296 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
5298 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
5300 * makefile: Pass in /unsafe.
5302 2001-12-13 Miguel de Icaza <miguel@ximian.com>
5304 * class.cs (MakeKey): Kill routine.
5306 * class.cs (TypeContainer.Define): Correctly define explicit
5307 method implementations (they require the full interface name plus
5310 * typemanager.cs: Deply the PtrHashtable here and stop using the
5311 lame keys. Things work so much better.
5313 This of course broke everyone who depended on `RegisterMethod' to
5314 do the `test for existance' test. This has to be done elsewhere.
5316 * support.cs (PtrHashtable): A hashtable that avoid comparing with
5317 the object stupid Equals method (because, that like fails all over
5318 the place). We still do not use it.
5320 * class.cs (TypeContainer.SetRequiredInterface,
5321 TypeContainer.RequireMethods): Killed these two routines and moved
5322 all the functionality to RegisterRequiredImplementations.
5324 (TypeContainer.RegisterRequiredImplementations): This routine now
5325 registers all the implementations required in an array for the
5326 interfaces and abstract methods. We use an array of structures
5327 which can be computed ahead of time to reduce memory usage and we
5328 also assume that lookups are cheap as most classes will not
5329 implement too many interfaces.
5331 We also avoid creating too many MethodSignatures.
5333 (TypeContainer.IsInterfaceMethod): Update and optionally does not
5334 clear the "pending" bit if we find that there are problems with
5337 (TypeContainer.VerifyPendingMethods): Update to report errors of
5338 methods that look like implementations but are not.
5340 (TypeContainer.Define): Add support for explicit interface method
5343 2001-12-12 Miguel de Icaza <miguel@ximian.com>
5345 * typemanager.cs: Keep track of the parameters here instead of
5346 being a feature of the TypeContainer.
5348 * class.cs: Drop the registration of parameters here, as
5349 InterfaceMethods are also interface declarations.
5351 * delegate.cs: Register methods with the TypeManager not only with
5352 the TypeContainer. This code was buggy.
5354 * interface.cs: Full registation here.
5356 2001-12-11 Miguel de Icaza <miguel@ximian.com>
5358 * expression.cs: Remove reducer for binary expressions, it can not
5361 * const.cs: Put here the code that used to go into constant.cs
5363 * constant.cs: Put here the code for constants, this is a new base
5366 * literal.cs: Make Literal derive from Constant.
5368 2001-12-09 Miguel de Icaza <miguel@ximian.com>
5370 * statement.cs (Return.Emit): Report error 157 if the user
5371 attempts to return from a finally block.
5373 (Return.Emit): Instead of emitting a return, jump to the end of
5376 * codegen.cs (EmitContext): ReturnValue, ReturnLabel: new
5377 LocalBuilder to store the result of the function. ReturnLabel is
5378 the target where we jump.
5381 2001-12-09 Radek Doulik <rodo@ximian.com>
5383 * cs-parser.jay: remember alias in current namespace
5385 * ecore.cs (SimpleName::DoResolve): use aliases for types or
5388 * class.cs (LookupAlias): lookup alias in my_namespace
5390 * namespace.cs (UsingAlias): add alias, namespace_or_type pair to
5392 (LookupAlias): lookup alias in this and if needed in parent
5395 2001-12-08 Miguel de Icaza <miguel@ximian.com>
5399 * rootcontext.cs: (ModuleBuilder) Made static, first step into
5400 making things static. I need this to avoid passing the
5401 TypeContainer when calling ParameterType.
5403 * support.cs (InternalParameters.ParameterType): Remove ugly hack
5404 that did string manipulation to compute the type and then call
5405 GetType. Use Parameter.ParameterType instead.
5407 * cs-tokenizer.cs: Consume the suffix for floating values.
5409 * expression.cs (ParameterReference): figure out whether this is a
5410 reference parameter or not. Kill an extra variable by computing
5411 the arg_idx during emission.
5413 * parameter.cs (Parameters.GetParameterInfo): New overloaded
5414 function that returns whether a parameter is an out/ref value or not.
5416 (Parameter.ParameterType): The type of the parameter (base,
5417 without ref/out applied).
5419 (Parameter.Resolve): Perform resolution here.
5420 (Parameter.ExternalType): The full type (with ref/out applied).
5422 * statement.cs (Using.Emit, Using.EmitExpression): Implement
5423 support for expressions on the using statement.
5425 2001-12-07 Miguel de Icaza <miguel@ximian.com>
5427 * statement.cs (Using.EmitLocalVariableDecls): Split the
5428 localvariable handling of the using statement.
5430 (Block.EmitMeta): Keep track of variable count across blocks. We
5431 were reusing slots on separate branches of blocks.
5433 (Try.Emit): Emit the general code block, we were not emitting it.
5435 Check the type of the declaration to be an IDisposable or
5436 something that can be implicity converted to it.
5438 Emit conversions if required.
5440 * ecore.cs (EmptyExpression): New utility class.
5441 (Expression.ImplicitConversionExists): New utility function.
5443 2001-12-06 Miguel de Icaza <miguel@ximian.com>
5445 * statement.cs (Using): Implement.

5449 * statement.cs: Remove the explicit emit for the Leave opcode.
5450 (VariableInfo): Add a readonly field.
5452 2001-12-05 Miguel de Icaza <miguel@ximian.com>
5454 * ecore.cs (ConvCast): new class used to encapsulate the various
5455 explicit integer conversions that works in both checked and
5458 (Expression.ConvertNumericExplicit): Use new ConvCast class to
5459 properly generate the overflow opcodes.
5461 2001-12-04 Miguel de Icaza <miguel@ximian.com>
5463 * statement.cs: The correct type for the EmptyExpression is the
5464 element_type, not the variable type. Ravi pointed this out.
5466 2001-12-04 Ravi Pratap <ravi@ximian.com>
5468 * class.cs (Method::Define): Handle PInvoke methods specially
5469 by using DefinePInvokeMethod instead of the usual one.
5471 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
5472 above to do the task of extracting information and defining the method.
5474 2001-12-04 Ravi Pratap <ravi@ximian.com>
5476 * expression.cs (ArrayCreation::EmitStaticInitializers): Get rid
5477 of the condition for string type.
5479 (Emit): Move that here.
5481 (ArrayCreation::CheckIndices): Keep string literals in their expression
5484 (EmitDynamicInitializers): Handle strings appropriately.
5486 2001-12-04 Miguel de Icaza <miguel@ximian.com>

5494 2001-12-03 Miguel de Icaza <miguel@ximian.com>
5498 * statement.cs (GotoDefault), cs-parser.jay: Implement `goto
5501 (Foreach.Emit): Foreach on arrays was not setting
5502 up the loop variables (for break/continue).
5504 (GotoCase): Semi-implented.
5506 2001-12-03 Ravi Pratap <ravi@ximian.com>
5508 * attribute.cs (CheckAttribute): Handle system attributes by using
5509 Attribute.GetAttributes to examine information we need.

5555 * expression.cs (Probe, Is, As): Split Probe in two classes Is and
5556 As that share bits of the implementation. Is returns a boolean,
5557 while As returns the Type that is being probed.
5559 2001-12-01 Ravi Pratap <ravi@ximian.com>
5561 * enum.cs (LookupEnumValue): Re-write various bits, return an object value
5562 instead of a Literal - much easier.
5564 (EnumInTransit): Remove - utterly useless :-)
5566 (Populate): Re-write bits - remove duplicate code etc. The code is much neater now.
5568 * expression.cs (MemberLookup): Cope with user-defined enums when they are in transit.
5570 * enum.cs (LookupEnumValue): Auto-compute next values by going down the dependency
5571 chain when we have no associated expression.

5632 in the case when we are looking for MemberTypes.Field
5634 * expression.cs (MemberAccess::DoResolve): Check that in the
5635 case we are a FieldExpr and a Literal, we are not being accessed
5636 by an instance reference.

5695 * expression.cs (ArrayCreation::CheckIndices): Get rid of the require_constant
5696 parameter. Apparently, any expression is allowed.
5698 (ValidateInitializers): Update accordingly.
5700 (CheckIndices): Fix some tricky bugs thanks to recursion.
5702 * delegate.cs (NewDelegate::DoResolve): Re-write large portions as
5703 I was being completely brain-dead.

5718 2001-11-22 Miguel de Icaza <miguel@ximian.com>
5720 * statement.cs (If.Emit): Fix a bug that generated incorrect code
5721 on If. Basically, we have to return `true' (ie, we do return to
5722 our caller) only if both branches of the if return.
5724 * expression.cs (Binary.Emit): LogicalOr and LogicalAnd are
5725 short-circuit operators, handle them as short circuit operators.
5727 (Cast.DoResolve): Resolve type.
5728 (Cast.Cast): Take an expression as the target type.
5730 * cs-parser.jay (cast_expression): Remove old hack that only
5731 allowed a limited set of types to be handled. Now we take a
5732 unary_expression and we resolve to a type during semantic
5735 Use the grammar productions from Rhys to handle casts (this is
5736 not complete like Rhys syntax yet, we fail to handle that corner
5737 case that C# has regarding (-x), but we will get there.
5739 2001-11-22 Ravi Pratap <ravi@ximian.com>
5741 * class.cs (EmitFieldInitializer): Take care of the case when we have a
5742 field which is an array type.

5746 * typemanager.cs (MakeKey): Implement.
5748 (everywhere): Use the above appropriately.
5750 * cs-parser.jay (for_statement): Update for array initialization while
5751 declaring variables.
5753 * ecore.cs : The error message was correct, it's the variable's names that
5754 were misleading ;-) Make the code more readable.
5756 (MemberAccess::DoResolve): Fix the code which handles Enum literals to set
5757 the correct type etc.
5759 (ConvertExplicit): Handle Enum types by examining the underlying type.
5761 2001-11-21 Ravi Pratap <ravi@ximian.com>

5774 BindingFlags.Instance as well
5776 * ecore.cs (Expression.TryImplicitIntConversion): Wrap the result
5777 implicit int literal conversion in an empty cast so that we
5778 propagate the right type upstream.
5780 (UnboxCast): new class used to unbox value types.
5781 (Expression.ConvertExplicit): Add explicit type conversions done
5784 (Expression.ImplicitNumericConversion): Oops, forgot to test for
5785 the target type before applying the implicit LongLiterals to ULong
5788 2001-11-21 Miguel de Icaza <miguel@ximian.com>
5790 * cs-parser.jay (for_statement): Reworked the way For works: now
5791 we declare manually any variables that are introduced in
5792 for_initializer to solve the problem of having out-of-band code
5793 emition (that is what got for broken).
5795 (declaration_statement): Perform the actual variable declaration
5796 that used to be done in local_variable_declaration here.
5798 (local_variable_declaration): Do not declare anything, just pass
5799 the information on a DictionaryEntry
5801 2001-11-20 Ravi Pratap <ravi@ximian.com>
5803 * expression.cs (ArrayCreation::CheckIndices): The story continues :-) Complete
5804 re-write of the logic to now make it recursive.
5806 (UpdateIndices): Re-write accordingly.
5808 Store element data in a separate ArrayData list in the above methods.

5826 * cs-parser.jay (constant_declarator): Use VariableDeclaration instead of
5827 DictionaryEntry since we need location info too.
5829 (constant_declaration): Update accordingly.
5831 * expression.cs (ArrayCreation): Make ValidateInitializers simpler by factoring
5832 code into another method : UpdateIndices.
5834 2001-11-18 Ravi Pratap <ravi@ximian.com>

5866 we can use this elsewhere.
5868 * statement.cs: Finish implementation of foreach for single
5871 * cs-parser.jay: Use an out-of-band stack to pass information
5872 around, I wonder why I need this.
5874 foreach_block: Make the new foreach_block the current_block.
5876 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
5877 function used to return a static Parameters structure. Used for
5878 empty parameters, as those are created very frequently.
5880 * cs-parser.jay, class.cs: Use GetEmptyReadOnlyParameters
5882 2001-11-15 Ravi Pratap <ravi@ximian.com>
5884 * interface.cs : Default modifier is private, not public. The
5885 make verify test passes again.
5887 2001-11-15 Ravi Pratap <ravi@ximian.com>
5889 * support.cs (ReflectionParameters): Fix logic to determine
5890 whether the last parameter is a params one. Test 9 passes again.
5892 * delegate.cs (Populate): Register the builders we define with
5893 RegisterParameterForBuilder. Test 19 passes again.
5895 * cs-parser.jay (property_declaration): Reference $6 instead
5896 of $$ to get at the location.
5898 (indexer_declaration): Similar stuff.
5902 * class.cs (Property): Register parameters for the Get and Set methods
5903 if they exist. Test 23 passes again.
5905 * expression.cs (ArrayCreation::Emit): Pass null for the method in the
5906 call to EmitArguments as we are sure there aren't any params arguments.
5907 Test 32 passes again.
5909 * suppor.cs (ParameterDesc, ParameterModifier): Fix trivial bug causing
5910 IndexOutOfRangeException.
5912 * class.cs (Property::Define): Register property using TypeManager.RegisterProperty
5913 Test 33 now passes again.
5915 2001-11-15 Miguel de Icaza <miguel@ximian.com>
5917 * cs-parser.jay: Kill horrendous hack ($??? = lexer.Location) that
5918 broke a bunch of things. Will have to come up with a better way
5919 of tracking locations.

5923 2001-11-09 Miguel de Icaza <miguel@ximian.com>

5940 and cons_param_array_attribute (ConstructorInfo for
5941 ParamArrayAttribute).,

5944 way we can report the error correctly for missing return values.
5946 * class.cs (Method.Emit): Clean up.
5948 * expression.cs (Argument.Resolve): Take another argument: the
5949 location where this argument is used. Notice that this is not
5950 part of the "Argument" class as to reduce the size of the
5951 structure (we know the approximate location anyways).
5953 Test if the argument is a variable-reference, if not, then
5954 complain with a 206.
5956 (Argument.Emit): Emit addresses of variables.
5958 (Argument.FullDesc): Simplify.
5960 (Invocation.DoResolve): Update for Argument.Resolve.
5962 (ElementAccess.DoResolve): ditto.

5987 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
5988 enumerations that are used in heavily used structures derive from
5989 byte in a laughable and pathetic attempt to reduce memory usage.
5990 This is the kind of pre-optimzations that you should not do at
5991 home without adult supervision.
5993 * expression.cs (UnaryMutator): New class, used to handle ++ and
5994 -- separatedly from the other unary operators. Cleans up the
5995 code, and kills the ExpressionStatement dependency in Unary.
5997 (Unary): Removed `method' and `Arguments' from this class, making
5998 it smaller, and moving it all to SimpleCall, so I can reuse this
5999 code in other locations and avoid creating a lot of transient data
6000 strucutres when not required.
6002 * cs-parser.jay: Adjust for new changes.
6004 2001-11-11 Miguel de Icaza <miguel@ximian.com>
6006 * enum.cs (Enum.Populate): If there is a failure during
6009 * cs-parser.jay (opt_enum_base): we used to catch type errors

6074 * expression.cs (MemberAccess.DoResolve): Adjust code to obtain the value
6075 of a fieldinfo using the above, when dealing with a FieldBuilder.

6122 2001-11-09 Miguel de Icaza <miguel@ximian.com>
6124 * cs-parser.jay: A for_initializer if is a
6125 local_variable_declaration really ammount to have an implicit
6126 block with the variable declaration and no initializer for for.

6161 Emit method everywhere.
6163 * enum.cs (Enum): Revamp to use the same definition semantics as delegates so
6164 we have a DefineEnum, CloseEnum etc. The previous way of doing things was not right
6165 as we had no way of defining nested enums !
6167 * rootcontext.cs : Adjust code accordingly.
6169 * typemanager.cs (AddEnumType): To keep track of enum types separately.
6171 2001-11-07 Ravi Pratap <ravi@ximian.com>

6238 IStackStore as the order in which arguments are passed reflects
6241 * assign.cs: Instead of using expr.ExprClass to select the way of
6242 assinging, probe for the IStackStore/IAssignMethod interfaces.
6244 * typemanager.cs: Load InitializeArray definition.
6246 * rootcontext.cs (RootContext.MakeStaticData): Used to define
6247 static data that can be used to initialize arrays.

6379 Parameter.Modifier and not a string.
6381 (ReflectionParameters, InternalParameters): Update accordingly.
6383 * expression.cs (Argument::GetParameterModifier): Same here.
6385 * support.cs (InternalParameters::ParameterType): Find a better way of determining
6386 if we are a ref/out parameter. Actually, the type shouldn't be holding the '&'
6387 symbol in it at all so maybe this is only for now.
6389 2001-10-30 Ravi Pratap <ravi@ximian.com>
6391 * support.cs (InternalParameters): Constructor now takes an extra argument
6392 which is the actual Parameters class.

6842 methods on value types. We need to pass the address to structure
6843 methods rather than the object itself. (The equivalent code to
6844 emit "this" for structures leaves the entire structure on the
6845 stack instead of a pointer to it).
6847 (ParameterReference::DoResolve): Compute the real index for the
6848 argument based on whether the method takes or not a `this' pointer
6849 (ie, the method is static).

6890 to TypeContainer mapping to see if a type is user-defined.
6892 * class.cs (TypeContainer::CloseType): Implement.

7012 * class.cs: Catch static methods having the flags override,
7013 virtual or abstract.
7015 * expression.cs (UserCast): This user cast was not really doing
7016 what it was supposed to do. Which is to be born in fully resolved
7017 state. Parts of the resolution were being performed at Emit time!
7021 2001-10-05 Miguel de Icaza <miguel@ximian.com>
7023 * expression.cs: Implicity convert the result from UserCast.

7049 UserDefinedConversion.

7091 instead of inside a tight loop.

7094 hashtable so we can report interface vs abstract method mismatch.
7096 2001-10-03 Miguel de Icaza <miguel@ximian.com>
7098 * report.cs: Make all of it static.
7100 * rootcontext.cs: Drop object_type and value_type computations, as
7101 we have those in the TypeManager anyways.

7111 condition is reached.
7113 2001-10-03 Ravi Pratap <ravi@ximian.com>
7115 * expression.cs (Binary::DoNumericPromotions): Fix the case when
7116 we do a forcible conversion regardless of type, to check if
7117 ForceConversion returns a null.
7119 (Binary::error19): Use location to report error.
7121 (Unary::error23): Use location here too.
7123 * ../errors/cs0019.cs : Check in.
7125 * ../errors/cs0023.cs : Check in.
7127 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
7128 case of a non-null MethodInfo object with a length of 0 !
7130 (Binary::ResolveOperator): Flag error if overload resolution fails to find
7131 an applicable member - according to the spec :-)
7132 Also fix logic to find members in base types.
7134 (Unary::ResolveOperator): Same here.
7136 (Unary::report23): Change name to error23 and make first argument a TypeContainer
7137 as I was getting thoroughly confused between this and error19 :-)
7139 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
7140 (::FindMostEncompassedType): Implement.
7141 (::FindMostEncompassingType): Implement.
7142 (::StandardConversionExists): Implement.
7144 (UserImplicitCast): Re-vamp. We now need info about most specific
7145 source and target types so that we can do the necessary conversions.
7147 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
7148 mathematical union with no duplicates.
7150 2001-10-03 Miguel de Icaza <miguel@ximian.com>
7152 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
7153 in order from base classes to child classes, so that we can in
7154 child classes look up in our parent for method names and
7155 attributes (required for handling abstract, virtual, new, override
7156 constructs: we need to instrospect our base class, and if we dont
7157 populate the classes in order, the introspection might be
7158 incorrect. For example, a method could query its parent before
7159 the parent has any methods and would determine that the parent has
7160 no abstract methods (while it could have had them)).
7162 (RootContext::CreateType): Record the order in which we define the
7165 2001-10-02 Miguel de Icaza <miguel@ximian.com>
7167 * class.cs (TypeContainer::Populate): Also method definitions can
7168 fail now, keep track of this.
7170 (TypeContainer::FindMembers): Implement support for
7171 DeclaredOnly/noDeclaredOnly flag.
7173 (Constructor::Emit) Return the ConstructorBuilder.
7175 (Method::Emit) Return the MethodBuilder.
7176 Check for abstract or virtual methods to be public.
7178 * rootcontext.cs (RootContext::CreateType): Register all the
7179 abstract methods required for the class to be complete and the
7180 interface methods that must be implemented.
7182 * cs-parser.jay: Report error 501 (method requires body if it is
7183 not marked abstract or extern).
7185 * expression.cs (TypeOf::Emit): Implement.
7187 * typemanager.cs: runtime_handle_type, new global type.
7189 * class.cs (Property::Emit): Generate code for properties.
7191 2001-10-02 Ravi Pratap <ravi@ximian.com>
7193 * expression.cs (Unary::ResolveOperator): Find operators on base type
7194 too - we now conform exactly to the spec.
7196 (Binary::ResolveOperator): Same here.
7198 * class.cs (Operator::Define): Fix minor quirk in the tests.
7200 * ../errors/cs0215.cs : Added.
7202 * ../errors/cs0556.cs : Added.
7204 * ../errors/cs0555.cs : Added.
7206 2001-10-01 Miguel de Icaza <miguel@ximian.com>
7208 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
7209 single integer which is really efficient
7211 2001-10-01 Ravi Pratap <ravi@ximian.com>
7213 * expression.cs (Expression::ImplicitUserConversion): Use location
7214 even in the case when we are examining True operators.
7216 * class.cs (Operator::Define): Perform extensive checks to conform
7217 with the rules for operator overloading in the spec.
7219 * expression.cs (Expression::ImplicitReferenceConversion): Implement
7220 some of the other conversions mentioned in the spec.
7222 * typemanager.cs (array_type): New static member for the System.Array built-in
7225 (cloneable_interface): For System.ICloneable interface.
7227 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
7228 we start resolving the tree and populating types.
7230 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
7232 2001-10-01 Miguel de Icaza <miguel@ximian.com>
7234 * expression.cs (Expression::ExprClassFromMemberInfo,
7235 Expression::Literalize): Create literal expressions from
7236 FieldInfos which are literals.
7238 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
7239 type casts, because they were wrong. The test suite in tests
7242 (ImplicitNumericConversion): ushort to ulong requires a widening
7245 Int32 constant to long requires widening cast as well.
7247 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
7248 for integers because the type on the stack is not i4.
7250 2001-09-30 Miguel de Icaza <miguel@ximian.com>
7252 * expression.cs (report118): require location argument.
7254 * parameter.cs: Do not dereference potential null value.
7256 * class.cs: Catch methods that lack the `new' keyword when
7257 overriding a name. Report warnings when `new' is used without
7258 anything being there to override.
7260 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
7262 * class.cs: Only add constructor to hashtable if it is non-null
7263 (as now constructors can fail on define).
7265 (TypeManager, Class, Struct): Take location arguments.
7267 Catch field instance initialization in structs as errors.
7269 accepting_filter: a new filter for FindMembers that is static so
7270 that we dont create an instance per invocation.
7272 (Constructor::Define): Catch errors where a struct constructor is
7275 * cs-parser.jay: Pass location information for various new
7278 * delegate.cs (Delegate): take a location argument.
7280 * driver.cs: Do not call EmitCode if there were problesm in the
7281 Definition of the types, as many Builders wont be there.
7283 * decl.cs (Decl::Decl): Require a location argument.
7285 * cs-tokenizer.cs: Handle properly hex constants that can not fit
7286 into integers, and find the most appropiate integer for it.
7288 * literal.cs: Implement ULongLiteral.
7290 * rootcontext.cs: Provide better information about the location of
7291 failure when CreateType fails.
7293 2001-09-29 Miguel de Icaza <miguel@ximian.com>
7295 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
7298 * expression.cs (Binary::CheckShiftArguments): Add missing type
7300 (Binary::ResolveOperator): Add type to the logical and and logical
7301 or, Bitwise And/Or and Exclusive Or code paths, it was missing
7304 (Binary::DoNumericPromotions): In the case where either argument
7305 is ulong (and most signed types combined with ulong cause an
7306 error) perform implicit integer constant conversions as well.
7308 2001-09-28 Miguel de Icaza <miguel@ximian.com>
7310 * expression.cs (UserImplicitCast): Method should always be
7312 (Invocation::BetterConversion): Simplified test for IntLiteral.
7314 (Expression::ImplicitNumericConversion): Split this routine out.
7315 Put the code that performs implicit constant integer conversions
7318 (Expression::Resolve): Become a wrapper around DoResolve so we can
7319 check eclass and type being set after resolve.
7321 (Invocation::Badness): Remove this dead function
7323 (Binary::ResolveOperator): Do not compute the expensive argumnets
7324 unless we have a union for it.
7326 (Probe::Emit): Is needs to do an isinst and then
7327 compare against null.
7329 (::CanConvert): Added Location argument. If the Location argument
7330 is null (Location.Null), then we do not report errors. This is
7331 used by the `probe' mechanism of the Explicit conversion. We do
7332 not want to generate an error for something that the user
7333 explicitly requested to be casted. But the pipeline for an
7334 explicit cast first tests for potential implicit casts.
7336 So for now, if the Location is null, it means `Probe only' to
7337 avoid adding another argument. Might have to revise this
7340 (ClassCast): New class used to type cast objects into arbitrary
7341 classes (used in Explicit Reference Conversions).
7343 Implement `as' as well.
7345 Reverted all the patches from Ravi below: they were broken:
7347 * The use of `level' as a mechanism to stop recursive
7348 invocations is wrong. That was there just to catch the
7349 bug with a strack trace but not as a way of addressing
7352 To fix the problem we have to *understand* what is going
7353 on and the interactions and come up with a plan, not
7354 just get things going.
7356 * The use of the type conversion cache that I proposed
7357 last night had an open topic: How does this work across
7358 protection domains. A user defined conversion might not
7359 be public in the location where we are applying the
7360 conversion, a different conversion might be selected
7361 (ie, private A->B (better) but public B->A (worse),
7362 inside A, A->B applies, but outside it, B->A will
7365 * On top of that (ie, even if the above is solved),
7366 conversions in a cache need to be abstract. Ie, `To
7367 convert from an Int to a Short use an OpcodeCast', not
7368 `To convert from an Int to a Short use the OpcodeCast on
7369 the variable 5' (which is what this patch was doing).
7371 2001-09-28 Ravi Pratap <ravi@ximian.com>
7373 * expression.cs (Invocation::ConversionExists): Re-write to use
7374 the conversion cache
7376 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
7377 cache all conversions done, not just user-defined ones.
7379 (Invocation::BetterConversion): The real culprit. Use ConversionExists
7380 to determine if a conversion exists instead of acutually trying to
7381 perform the conversion. It's faster too.
7383 (Expression::ConvertExplicit): Modify to use ConversionExists to check
7384 and only then attempt the implicit conversion.
7386 2001-09-28 Ravi Pratap <ravi@ximian.com>
7388 * expression.cs (ConvertImplicit): Use a cache for conversions
7389 already found. Check level of recursion and bail out if necessary.
7391 2001-09-28 Miguel de Icaza <miguel@ximian.com>
7393 * typemanager.cs (string_concat_string_string, string_concat_object_object):
7394 Export standard methods that we expect for string operations.
7396 * statement.cs (Block::UsageWarning): Track usage of variables and
7397 report the errors for not used variables.
7399 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
7402 2001-09-27 Miguel de Icaza <miguel@ximian.com>
7404 * codegen.cs: remove unnneded code
7406 * expression.cs: Removed BuiltinTypeAccess class
7408 Fix the order in which implicit conversions are
7411 The previous fixed dropped support for boxed conversions (adding a
7412 test to the test suite now)
7414 (UserImplicitCast::CanConvert): Remove test for source being null,
7415 that code is broken. We should not feed a null to begin with, if
7416 we do, then we should track the bug where the problem originates
7417 and not try to cover it up here.
7419 Return a resolved expression of type UserImplicitCast on success
7420 rather than true/false. Ravi: this is what I was talking about,
7421 the pattern is to use a static method as a "constructor" for
7424 Also, do not create arguments until the very last minute,
7425 otherwise we always create the arguments even for lookups that
7426 will never be performed.
7428 (UserImplicitCast::Resolve): Eliminate, objects of type
7429 UserImplicitCast are born in a fully resolved state.
7431 * typemanager.cs (InitCoreTypes): Init also value_type
7434 * expression.cs (Cast::Resolve): First resolve the child expression.
7436 (LValue): Add new method AddressOf to be used by
7439 Change the argument of Store to take an EmitContext instead of an
7440 ILGenerator, because things like FieldExpr need to be able to call
7441 their children expression to generate the instance code.
7443 (Expression::Error, Expression::Warning): Sugar functions for
7446 (Expression::MemberLookup): Accept a TypeContainer instead of a
7447 Report as the first argument.
7449 (Expression::ResolvePrimary): Killed. I still want to improve
7450 this as currently the code is just not right.
7452 (Expression::ResolveMemberAccess): Simplify, but it is still
7455 (Unary::Resolve): Catch errors in AddressOf operators.
7457 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
7458 index to a byte for the short-version, or the compiler will choose
7459 the wrong Emit call, which generates the wrong data.
7461 (ParameterReference::Emit, ::Store): same.
7463 (FieldExpr::AddressOf): Implement.
7465 * typemanager.cs: TypeManager: made public variable instead of
7468 * driver.cs: document --fatal.
7470 * report.cs (ErrorMessage, WarningMessage): new names for the old
7471 Error and Warning classes.
7473 * cs-parser.jay (member_access): Turn built-in access to types
7474 into a normal simplename
7476 2001-09-27 Ravi Pratap <ravi@ximian.com>

7479 with q being null, since this was introducing a bug.
7481 * expression.cs (ConvertImplicit): Do built-in conversions first.
7483 2001-09-27 Ravi Pratap <ravi@ximian.com>
7485 * expression.cs (UserImplicitCast::Resolve): Fix bug.
7487 2001-09-27 Ravi Pratap <ravi@ximian.com>
7489 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
7490 I had introduced long ago (what's new ?).
7492 * expression.cs (UserImplicitCast::CanConvert): Static method to do
7493 the work of all the checking.
7494 (ConvertImplicit): Call CanConvert and only then create object if necessary.
7495 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
7497 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
7498 that is the right way.
7500 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
7501 overloading resolution. Use everywhere instead of cutting and pasting code.
7503 (Binary::ResolveOperator): Use MakeUnionSet.
7505 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
7506 we have to convert to bool types. Not complete yet.
7508 2001-09-27 Miguel de Icaza <miguel@ximian.com>
7510 * typemanager.cs (TypeManager::CSharpName): support ushort.
7512 * expression.cs (Expression::TryImplicitIntConversion): Attempts
7513 to provide an expression that performsn an implicit constant int
7514 conversion (section 6.1.6).
7515 (Expression::ConvertImplicitRequired): Reworked to include
7516 implicit constant expression conversions.
7518 (Expression::ConvertNumericExplicit): Finished.
7520 (Invocation::Emit): If InstanceExpression is null, then it means
7521 that we perform a call on this.
7523 2001-09-26 Miguel de Icaza <miguel@ximian.com>
7525 * expression.cs (Unary::Emit): Remove some dead code.
7526 (Probe): Implement Resolve and Emit for `is'.
7527 (Expression::ConvertImplicitRequired): Attempt to do constant
7528 expression conversions here. Maybe should be moved to
7529 ConvertImplicit, but I am not sure.
7530 (Expression::ImplicitLongConstantConversionPossible,
7531 Expression::ImplicitIntConstantConversionPossible): New functions
7532 that tell whether is it possible to apply an implicit constant
7533 expression conversion.
7535 (ConvertNumericExplicit): Started work on explicit numeric
7538 * cs-parser.jay: Update operator constants.
7540 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
7541 (Parameters::GetSignature): Hook up VerifyArgs here.
7542 (Parameters::VerifyArgs): Verifies that no two arguments have the
7545 * class.cs (Operator): Update the operator names to reflect the
7546 ones that the spec expects (as we are just stringizing the
7549 * expression.cs (Unary::ResolveOperator): Fix bug: Use
7550 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
7551 previous usage did only work for our methods.
7552 (Expression::ConvertImplicit): Handle decimal implicit numeric
7553 conversions as well.
7554 (Expression::InternalTypeConstructor): Used to invoke constructors
7555 on internal types for default promotions.
7557 (Unary::Emit): Implement special handling for the pre/post
7558 increment/decrement for overloaded operators, as they need to have
7559 the same semantics as the other operators.
7561 (Binary::ResolveOperator): ditto.
7562 (Invocation::ConversionExists): ditto.
7563 (UserImplicitCast::Resolve): ditto.
7565 2001-09-26 Ravi Pratap <ravi@ximian.com>
7567 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded
7568 operator, return after emitting body. Regression tests pass again !
7570 * expression.cs (ConvertImplicit): Take TypeContainer as first argument
7571 (Unary::ForceConversion, Binary::ForceConversion): Ditto.
7572 (Invocation::OverloadResolve): Ditto.
7573 (Invocation::BetterFunction, BetterConversion, ConversionExists): Ditto.
7575 * everywhere : update calls to the above methods accordingly.
7577 2001-09-26 Miguel de Icaza <miguel@ximian.com>
7579 * assign.cs (Assign): Make it inherit from ExpressionStatement.
7581 * expression.cs (ExpressionStatement): New base class used for
7582 expressions that can appear in statements, so that we can provide
7583 an alternate path to generate expression that do not leave a value
7586 (Expression::Emit, and all the derivatives): We no longer return
7587 whether a value is left on the stack or not. Every expression
7588 after being emitted leaves a single value on the stack.
7590 * codegen.cs (EmitContext::EmitStatementExpression): Use the
7591 facilties of ExpressionStatement if possible.
7593 * cs-parser.jay: Update statement_expression.

7601 * expression.cs (Binary::ResolveOperator): Had forgottten to set
7602 the type of the expression to the return type of the method if
7603 we have an overloaded operator match ! The regression tests pass again !
7604 (Unary::ResolveOperator): Ditto.
7606 * expression.cs (Invocation::ConversionExists): Correct the member lookup
7607 to find "op_Implicit", not "implicit" ;-)
7608 (UserImplicitCast): New class to take care of user-defined implicit conversions.

7614 (ConvertImplicit): Do user-defined conversion if it exists.
7616 2001-09-24 Miguel de Icaza <miguel@ximian.com>
7618 * assign.cs: track location.
7619 (Resolve): Use implicit conversions on assignment.
7621 * literal.cs: Oops. Not good, Emit of short access values should

7624 * expression.cs (Unary::Emit): Emit code for -expr.
7626 (Unary::ResolveOperator): Handle `Substract' for non-constants
7627 (substract from zero from the non-constants).

7662 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
7663 Also take an additional TypeContainer argument.
7665 * All over : Pass in TypeContainer as argument to OverloadResolve.
7667 * typemanager.cs (CSharpName): Update to check for the string type and return
7670 * expression.cs (Invocation::FullMethodDesc): New static method to return a string fully describing
7673 2001-09-21 Ravi Pratap <ravi@ximian.com>
7675 * expression.cs (Invocation::OverloadResolve): Re-write to conform more to the spec.
7676 (Invocation::BetterFunction): Implement.
7677 (Invocation::BetterConversion): Implement.
7678 (Invocation::ConversionExists): Skeleton, no implementation yet.
7680 Okay, things work fine !
7682 2001-09-21 Miguel de Icaza <miguel@ximian.com>
7684 * typemanager.cs: declare and load enum_type, delegate_type and
7687 * expression.cs (Expression::Emit): Now emit returns a value that
7688 tells whether a value is left on the stack or not. This strategy
7689 might be reveted tomorrow with a mechanism that would address
7690 multiple assignments.
7691 (Expression::report118): Utility routine to report mismatches on
7694 (Unary::Report23): Report impossible type/operator combination
7697 (Unary::IsIncrementableNumber): Whether the type can be

7731 * expression.cs (SimpleName::ResolveSimpleName): Error if we can
7734 * cs-parser.jay (QualifierIdentifier): Pass location to SimpleName
7737 * statement.cs (Block::EmitMeta): Reuse the count across all the variables,
7738 otherwise nested blocks end up with the same index.
7740 * codegen.cs (CodeGen::EmitTopBlock): Pass initial sequence
7742 * expression.cs: Instead of having FIXMEs in the Resolve
7743 functions, throw exceptions so it is obvious that we are facing a
7746 * cs-parser.jay (invocation_expression): Pass Location information.
7748 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
7749 Use a basename for those routines because .NET does not like paths

7761 * expression.cs (Unary::ResolveOperator): return the child
7762 expression for expressions which are just +expr.

7766 expression conversions'.
7768 * literal.cs (LongLiteral): Implement long literal class.
7769 (IntLiteral): export the `Value' of the intliteral.
7771 2001-09-19 Ravi Pratap <ravi@ximian.com>
7773 * expression.cs (Binary::Emit): Finally get the emission right ! Woo!
7775 * class.cs (Operator::Define): Change the methodname prefix to 'op_'

7790 Binary::ResolveOperator does for Binary expressions.
7791 (Unary.method, .Arguments): Add.
7792 (Unary::OperName): Implement.
7793 (Unary::ForceConversion): Copy and Paste !
7795 * class.cs (Operator::Define): Fix a small bug for the case when we have
7798 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
7799 for the inbuilt operators. Only overloading works for now ;-)
7801 2001-09-18 Miguel de Icaza <miguel@ximian.com>
7803 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
7804 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

7819 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
7820 the last instruction contains a return opcode to avoid generating
7821 the last `ret' instruction (this generates correct code, and it is
7822 nice to pass the peverify output).
7824 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
7825 initializer for static and instance variables.
7826 (Constructor::Emit): Allow initializer to be null in the case of
7827 static constructors. Only emit initializer for instance
7830 (TypeContainer::FindMembers): Return a null array if there are no

7834 scanning that for operators (or tried to access null variables before).
7836 * assign.cs (Assign::Emit): Handle instance and static fields.
7840 * driver.cs: Stop compilation if there are parse errors.
7842 * cs-parser.jay (constructor_declaration): Provide default base
7843 initializer for non-static constructors.

7845 initializers if none was specified.
7846 Catch the fact that constructors should not have parameters.
7848 * class.cs: Do not emit parent class initializers for static
7849 constructors, that should be flagged as an error.
7851 2001-09-18 Ravi Pratap <ravi@ximian.com>
7853 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
7854 Move back code into TypeContainer::Populate.

7883 (Expression::MemberLookup): Provide a version that allows to
7884 specify the MemberTypes and BindingFlags.
7886 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
7887 so it was not fetching variable information from outer blocks.
7889 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
7890 Beforefieldinit as it was buggy.
7892 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
7895 * class.cs (Constructor::Emit): Only emit if block is not null.

7939 (TypeContainer::Emit): Emit the operators we have too.

7971 * cs-parser.jay (namespace_declaration): Call RecordNamespace to
7974 * rootcontext.cs (IsNamespace): Fixed it :-)
7976 2001-09-14 Miguel de Icaza <miguel@ximian.com>
7978 * class.cs (TypeContainer::FindMembers): Add support for

7989 * modifiers.cs: Do not use `parent', instead use the real type
7990 container to evaluate permission settings.
7992 * class.cs: Put Ravi's patch back in. He is right, and we will
7993 have to cope with the
7995 2001-09-14 Ravi Pratap <ravi@ximian.com>
7997 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

8002 * driver.cs: Added --parse option that only parses its input files
8005 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
8006 incorrect. IsTopLevel is not used to tell whether an object is
8007 root_types or not (that can be achieved by testing this ==
8008 root_types). But to see if this is a top-level *class* (not
8009 necessarly our "toplevel" container).
8011 2001-09-14 Ravi Pratap <ravi@ximian.com>
8013 * enum.cs (Enum::Define): Modify to call the Lookup method on the
8014 parent instead of a direct call to GetType.

8018 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
8019 Modifiers.TypeAttr. This should just be a call to that method.
8021 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
8022 object so that we can determine if we are top-level or not.
8024 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
8027 * enum.cs (Enum::Define): Ditto.
8029 * modifiers.cs (FieldAttr): Re-write.

8032 (TypeContainer::HaveStaticConstructor): New property to provide access
8033 to precisely that info.
8035 * modifiers.cs (MethodAttr): Re-write.
8036 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
8038 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
8039 of top-level types as claimed.
8041 2001-09-13 Miguel de Icaza <miguel@ximian.com>
8043 * expression.cs (MemberLookup): Fruitless attempt to lookup
8044 constructors. Maybe I need to emit default constructors? That
8045 might be it (currently .NET emits this for me automatically).
8046 (Invocation::OverloadResolve): Cope with Arguments == null.
8047 (Invocation::EmitArguments): new function, shared by the new
8049 (Invocation::Emit): Handle static and instance methods. Emit

8069 objects that we might have around.
8071 (Populate): Only initialize method_builders_to_methods once.
8073 * expression.cs (PropertyExpr): Initialize type from the
8076 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

8080 * expression.cs: Set the type for the int32/int32 argument case.
8081 (Binary::ResolveOperator): Set the return type to boolean for
8082 comparission operators
8084 * typemanager.cs: Remove debugging print code.
8086 (Invocation::Resolve): resolve type.
8088 * class.cs: Allocate a MemberInfo of the correct size, as the code
8089 elsewhere depends on the test to reflect the correct contents.
8091 (Method::) Keep track of parameters, due to System.Reflection holes
8093 (TypeContainer::Populate): Keep track of MethodBuilders to Method
8096 (TypeContainer::FindMembers): Use ArrayList and then copy an array
8097 of the exact size and return that.
8099 (Class::LookupMethodByBuilder): New function that maps
8100 MethodBuilders to its methods. Required to locate the information
8101 on methods because System.Reflection bit us again.
8103 * support.cs: New file, contains an interface ParameterData and
8104 two implementations: ReflectionParameters and InternalParameters
8105 used to access Parameter information. We will need to grow this
8108 * expression.cs (Invocation::GetParameterData): implement a cache
8109 and a wrapper around the ParameterData creation for methods.
8110 (Invocation::OverloadResolve): Use new code.
8112 2001-09-13 Ravi Pratap <ravi@ximian.com>

8123 initialized with the full type once it is resolved.
8125 2001-09-12 Miguel de Icaza <miguel@ximian.com>

8166 2001-09-12 Ravi Pratap <ravi@ximian.com>
8168 * class.cs (TypeContainer::FindMembers): Method which does exactly
8169 what Type.FindMembers does, only we don't have to use reflection. No
8172 * typemanager.cs (typecontainers): New hashtable to hold the corresponding
8173 typecontainer objects as we need to get at them.
8174 (TypeManager::AddUserType): Overload to take an extra argument, the TypeContainer.

8202 (Property::Define): Ditto.

8216 addOn_ and removeOn_
8218 * genericparser.cs (GenericParser::error): Overloaded method to handle the case

8624 (indexer_declarator): Implement actions.
8625 (parsing_indexer): New local boolean used to keep track of whether

8689 compiling corlib.dll)
8691 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
8692 on Expression Classification. Now all expressions have a method
8693 `Resolve' and a method `Emit'.
8695 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
8696 generation from working. Also add some temporary debugging
8699 2001-08-24 Miguel de Icaza <miguel@ximian.com>
8701 * codegen.cs: Lots of code generation pieces. This is only the
8702 beginning, will continue tomorrow with more touches of polish. We

8735 function, and implements a cache that will be useful later when I
8736 do error checking and the semantic analysis on the methods is

8739 and made a method, optional argument tells whether this is a class
8740 or a structure to apply the `has-this' bit.

8773 (Field::) use readonly public fields instead of properties also.
8775 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
8776 track of static constructors; If none is used, turn on
8777 BeforeFieldInit in the TypeAttributes.
8779 * cs-parser.jay (opt_argument_list): now the return can be null
8780 for the cases where there are no arguments.
8782 (constructor_declarator): If there is no implicit `base' or

8785 * modifiers.cs (MethodAttr): New static function maps a set of
8786 modifiers flags into a MethodAttributes enum
8787 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
8788 MethodAttr, TypeAttr to represent the various mappings where the
8790 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'

8815 instead of doing this always.
8817 * parameter.cs: Handle refs and out parameters.

8820 instead of the ParameterCollection, and then cast that to a
8823 * parameter.cs: Drop the use of ParameterCollection and use
8824 instead arrays of Parameters.

8850 the compiler so much faster. Wow. I rule!
8852 * driver.cs: Make sure we always load mscorlib first (for
8853 debugging purposes, nothing really important).
8855 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
8856 have moved to `CSC' rather than `CIR'. Oh man! The confussion!

8859 on namespaces that have been imported using the `using' keyword.
8861 * class.cs (TypeContainer::TypeAttr): Virtualize.

8923 RecordInterface instead.
8925 * cs-parser.jay: Updated to reflect changes above.
8927 * decl.cs (Definition): Keep track of the TypeBuilder type that
8928 represents this type here. Not sure we will use it in the long

9048 * gen-treedump.cs: Adapted for all the renaming.
9050 * expression.cs (Expression): this class now has a Type property
9051 which returns an expression Type.
9053 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
9054 `Type', as this has a different meaning now in the base
9056 2001-05-22 Miguel de Icaza <miguel@ximian.com>
9058 * interface.cs, class.cs: Removed from all the sources the
9059 references to signature computation, as we can not do method
9060 signature computation during the parsing time, as we are not
9061 trying to solve at that point distinguishing:
9065 void a (NS.Blah x) {}
9068 Which depending on the context might be valid or not, as we do not
9069 know if Blah is the same thing as NS.Blah at that point.
9071 * Redid everything so the code uses TypeRefs now instead of
9072 Types. TypeRefs are just temporary type placeholders, that need
9073 to be resolved. They initially have a pointer to a string and the
9074 current scope in which they are used. This is used later by the
9075 compiler to resolve the reference to an actual Type.
9077 * DeclSpace is no longer a CIR.Type, and neither are
9078 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
9079 are all DeclSpaces, but no Types.
9081 * type.cs (TypeRefManager): This implements the TypeRef manager,
9082 which keeps track of all the types that need to be resolved after
9083 the parsing has finished.
9085 2001-05-13 Miguel de Icaza <miguel@ximian.com>
9087 * ARGH. We are going to have to store `foreach' as a class rather
9088 than resolving it, as we need to verify error 1579 after name
9089 resolution. *OR* we could keep a flag that says `This request to
9090 IEnumerator comes from a foreach statement' which we can then use
9091 to generate the error.
9093 2001-05-10 Miguel de Icaza <miguel@ximian.com>
9095 * class.cs (TypeContainer.AddMethod): we now add methods to the
9096 MethodGroup instead of the method hashtable.
9098 * expression.cs: Add MethodGroup abstraction, which gets us one
9099 step closer to the specification in the way we handle method
9102 * cs-parser.jay (primary_expression): qualified_identifier now
9103 tried to match up an identifier to a local variable reference or
9104 to a parameter reference.
9106 current_local_parameters is now a parser global variable that
9107 points to the current parameters for the block, used during name
9110 (property_declaration): Now creates an implicit `value' argument to
9113 2001-05-09 Miguel de Icaza <miguel@ximian.com>
9115 * parameter.cs: Do not use `param' arguments as part of the
9116 signature, per the spec.
9118 2001-05-08 Miguel de Icaza <miguel@ximian.com>
9120 * decl.cs: Base class for classes, structs and interfaces. This
9121 is the "Declaration Space"
9123 * cs-parser.jay: Use CheckDef for checking declaration errors
9124 instead of having one on each function.
9126 * class.cs: Factor out some code for handling error handling in
9127 accordance to the "Declarations" section in the "Basic Concepts"
9128 chapter in the ECMA C# spec.
9130 * interface.cs: Make all interface member classes derive from
9131 InterfaceMemberBase.
9133 2001-05-07 Miguel de Icaza <miguel@ximian.com>
9135 * Many things: all interfaces are parsed and generated in
9136 gen-treedump. Support for member variables, constructors,
9137 destructors, properties, constants is there.
9139 Beginning of the IL backend, but very little done, just there for
9142 2001-04-29 Miguel de Icaza <miguel@ximian.com>
9144 * cs-parser.jay: Fix labeled statement.
9146 * cs-tokenizer.cs (escape): Escape " and ' always.
9147 ref_line, ref_name: keep track of the line/filename as instructed
9148 by #line by the compiler.
9151 2001-04-27 Miguel de Icaza <miguel@ximian.com>
9153 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
9154 to match the values in System.CodeDOM.
9156 Divid renamed to Divide.
9158 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
9160 (Statements.set): remove.
9162 * System.CodeDOM/CodeCatchClause.cs: always have a valid
9165 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
9166 falseStatements always have valid values.
9168 * cs-parser.jay: Use System.CodeDOM now.
