1 2002-09-09 Martin Baulig <martin@gnome.org>
3 * expression.cs (SizeOf.DoResolve): Sizeof is only allowed in unsafe
4 context. Fixes bug #30027.
6 * delegate.cs (NewDelegate.Emit): Use OpCodes.Ldvirtftn for
7 virtual functions. Fixes bug #30043, added test-164.cs.
9 2002-09-08 Ravi Pratap <ravi@ximian.com>
11 * attribute.cs : Fix a small NullRef crash thanks to my stupidity.
13 2002-09-08 Nick Drochak <ndrochak@gol.com>
15 * driver.cs: Use an object to get the windows codepage since it's not a
18 2002-09-08 Miguel de Icaza <miguel@ximian.com>
20 * statement.cs (For.Emit): for infinite loops (test == null)
21 return whether there is a break inside, not always "true".
23 * namespace.cs (UsingEntry): New struct to hold the name of the
24 using definition, the location where it is defined, and whether it
25 has been used in a successful type lookup.
27 * rootcontext.cs (NamespaceLookup): Use UsingEntries instead of
32 2002-09-06 Ravi Pratap <ravi@ximian.com>
34 * attribute.cs : Fix incorrect code which relied on catching
35 a NullReferenceException to detect a null being passed in
36 where an object was expected.
38 2002-09-06 Miguel de Icaza <miguel@ximian.com>
40 * statement.cs (Try): flag the catch variable as assigned
42 * expression.cs (Cast): Simplified by using ResolveType instead of
45 * statement.cs (Catch): Fix bug by using ResolveType.
47 2002-09-06 Ravi Pratap <ravi@ximian.com>
49 * expression.cs (BetterConversion): Special case for when we have
50 a NullLiteral as the argument and we have to choose between string
51 and object types - we choose string the way csc does.
53 * attribute.cs (Attribute.Resolve): Catch the
54 NullReferenceException and report error #182 since the Mono
55 runtime no more has the bug and having this exception raised means
56 we tried to select a constructor which takes an object and is
59 2002-09-05 Ravi Pratap <ravi@ximian.com>
61 * expression.cs (Invocation.OverloadResolve): Flag a nicer error
62 message (1502, 1503) when we can't locate a method after overload
63 resolution. This is much more informative and closes the bug
66 * interface.cs (PopulateMethod): Return if there are no argument
67 types. Fixes a NullReferenceException bug.
69 * attribute.cs (Attribute.Resolve): Ensure we allow TypeOf
70 expressions too. Previously we were checking only in one place for
71 positional arguments leaving out named arguments.
73 * ecore.cs (ImplicitNumericConversion): Conversion from underlying
74 type to the enum type is not allowed. Remove code corresponding to
77 (ConvertNumericExplicit): Allow explicit conversions from
78 the underlying type to enum type. This precisely follows the spec
79 and closes a bug filed by Gonzalo.
81 2002-09-04 Gonzalo Paniagua Javier <gonzalo@ximian.com>
84 * compiler.csproj.user: patch from Adam Chester (achester@bigpond.com).
86 2002-09-03 Miguel de Icaza <miguel@ximian.com>
88 * statement.cs (SwitchLabel.ResolveAndReduce): In the string case,
89 it was important that we stored the right value after the
90 reduction in `converted'.
92 2002-09-04 Martin Baulig <martin@gnome.org>
94 * location.cs (Location.SymbolDocument): Use full pathnames for the
97 2002-08-30 Miguel de Icaza <miguel@ximian.com>
99 * expression.cs (ComposedCast): Use DeclSparce.ResolveType instead
100 of the expression resolve mechanism, because that will catch the
101 SimpleName error failures.
103 (Conditional): If we can not resolve the
104 expression, return, do not crash.
106 2002-08-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>
109 (location): display token name instead of its number.
111 2002-08-28 Martin Baulig <martin@gnome.org>
113 * expression.cs (Binary.ResolveOperator): Don't silently return
114 but return an error if an operator cannot be applied between two
117 2002-08-28 Martin Baulig <martin@gnome.org>
119 * class.cs (Constructor.Define): Set the permission attributes
120 correctly instead of making all constructors public.
122 2002-08-28 Martin Baulig <martin@gnome.org>
124 * ecore.cs (Expression.DoResolve): Do a TypeManager.MemberLook
125 for private members before reporting a CS0103; if we find anything,
128 2002-08-28 Martin Baulig <martin@gnome.org>
130 * typemanager.cs (TypeManager.FilterWithClosure): It's not enough
131 to check whether `closure_start_type == closure_invocation_type',
132 we also need to check whether `m.DeclaringType == closure_invocation_type'
133 before bypassing the permission checks. We might be accessing
134 protected/private members from the base class.
135 (TypeManager.RealMemberLookup): Only set private_ok if private
136 members were requested via BindingFlags.NonPublic.
138 * ecore.cs (MethodGroupExpr.IsExplicitImpl): New property.
140 * expression.cs (MemberAccess.ResolveMemberAccess): Set
141 MethodGroupExpr.IsExplicitImpl if appropriate.
142 (Invocation.DoResolve): Don't report the CS0120 for explicit
143 interface implementations.
145 2002-08-27 Martin Baulig <martin@gnome.org>
147 * expression.cs (Invocation.DoResolve): If this is a static
148 method and we don't have an InstanceExpression, we must report
151 2002-08-25 Martin Baulig <martin@gnome.org>
153 * expression.cs (Binary.ResolveOperator): Don't allow `!=' and
154 `==' between a valuetype and an object.
156 2002-08-25 Miguel de Icaza <miguel@ximian.com>
158 * ecore.cs (TypeExpr): Provide a ToString method.
160 2002-08-24 Martin Baulig <martin@gnome.org>
162 * codegen.cs (CodeGen.InitMonoSymbolWriter): The symbol file is
163 now called proggie.dbg and it's a binary file.
165 2002-08-23 Martin Baulig <martin@gnome.org>
167 * decl.cs (MemberCache.AddMethods): Ignore varargs methods.
169 2002-08-23 Martin Baulig <martin@gnome.org>
171 * struct.cs (MyStructInfo.ctor): Make this work with empty
172 structs; it's not allowed to use foreach() on null.
174 2002-08-23 Martin Baulig <martin@gnome.org>
176 * codegen.cs (CodeGen.InitMonoSymbolWriter): Tell the symbol
177 writer the full pathname of the generated assembly.
179 2002-08-23 Martin Baulig <martin@gnome.org>
181 * statements.cs (FlowBranching.UsageVector.MergeChildren):
182 A `finally' block never returns or breaks; improved handling of
185 2002-08-23 Martin Baulig <martin@gnome.org>
187 * statement.cs (Throw.Resolve): Allow `throw null'.
189 2002-08-23 Martin Baulig <martin@gnome.org>
191 * expression.cs (MemberAccess.ResolveMemberAccess): If this is an
192 EventExpr, don't do a DeclaredOnly MemberLookup, but check whether
193 `ee.EventInfo.DeclaringType == ec.ContainerType'. The
194 MemberLookup would return a wrong event if this is an explicit
195 interface implementation and the class has an event with the same
198 2002-08-23 Martin Baulig <martin@gnome.org>
200 * statement.cs (Block.AddChildVariableNames): New public method.
201 (Block.AddChildVariableName): Likewise.
202 (Block.IsVariableNameUsedInChildBlock): Likewise.
203 (Block.AddVariable): Check whether a variable name has already
204 been used in a child block.
206 * cs-parser.jay (declare_local_variables): Mark all variable names
207 from the current block as being used in a child block in the
210 2002-08-23 Martin Baulig <martin@gnome.org>
212 * codegen.cs (CodeGen.InitializeSymbolWriter): Abort if we can't
213 find the symbol writer.
215 * driver.cs: csc also allows the arguments to /define being
216 separated by commas, not only by semicolons.
218 2002-08-23 Martin Baulig <martin@gnome.org>
220 * interface.cs (Interface.GetMembers): Added static check for events.
222 2002-08-15 Martin Baulig <martin@gnome.org>
224 * class.cs (MethodData.EmitDestructor): In the Expression.MemberLookup
225 call, use ec.ContainerType.BaseType as queried_type and invocation_type.
227 * ecore.cs (Expression.MemberLookup): Added documentation and explained
228 why the MethodData.EmitDestructor() change was necessary.
230 2002-08-20 Martin Baulig <martin@gnome.org>
232 * class.cs (TypeContainer.FindMembers): Added static check for events.
234 * decl.cs (MemberCache.AddMembers): Handle events like normal members.
236 * typemanager.cs (TypeHandle.GetMembers): When queried for events only,
237 use Type.GetEvents(), not Type.FindMembers().
239 2002-08-20 Martin Baulig <martin@gnome.org>
241 * decl.cs (MemberCache): Added a special method cache which will
242 be used for method-only searched. This ensures that a method
243 search will return a MethodInfo with the correct ReflectedType for
246 2002-08-20 Martin Baulig <martin@gnome.org>
248 * decl.cs (DeclSpace.FindMembers): Made this public.
250 2002-08-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
252 * delegate.cs: fixed build on windows.
253 [FIXME: Filed as bug #29150: MCS must report these errors.]
255 2002-08-19 Ravi Pratap <ravi@ximian.com>
257 * ecore.cs (StandardConversionExists): Return a false
258 if we are trying to convert the void type to anything else
259 since that is not allowed.
261 * delegate.cs (DelegateInvocation.DoResolve): Ensure that
262 we flag error 70 in the event an event is trying to be accessed
263 directly from outside the declaring type.
265 2002-08-20 Martin Baulig <martin@gnome.org>
267 * typemanager.cs, decl.cs: Moved MemberList, IMemberContainer and
268 MemberCache from typemanager.cs to decl.cs.
270 2002-08-19 Martin Baulig <martin@gnome.org>
272 * class.cs (TypeContainer): Implement IMemberContainer.
273 (TypeContainer.DefineMembers): Create the MemberCache.
274 (TypeContainer.FindMembers): Do better BindingFlags checking; only
275 return public members if BindingFlags.Public was given, check
276 whether members are static.
278 2002-08-16 Martin Baulig <martin@gnome.org>
280 * decl.cs (DeclSpace.Define): Splitted this in Define and
281 DefineMembers. DefineMembers is called first and initializes the
284 * rootcontext.cs (RootContext.DefineMembers): New function. Calls
285 DefineMembers() on all our DeclSpaces.
287 * class.cs (TypeContainer.Define): Moved all code to DefineMembers(),
288 but call DefineMembers() on all nested interfaces. We call their
289 Define() in our new Define() function.
291 * interface.cs (Interface): Implement IMemberContainer.
292 (Interface.Define): Moved all code except the attribute stuf to
294 (Interface.DefineMembers): Initialize the member cache.
296 * typemanager.cs (IMemberFinder): Removed this interface, we don't
297 need this anymore since we can use MemberCache.FindMembers directly.
299 2002-08-19 Martin Baulig <martin@gnome.org>
301 * typemanager.cs (MemberCache): When creating the cache for an
302 interface type, add all inherited members.
303 (TypeManager.MemberLookup_FindMembers): Changed `ref bool searching'
304 to `out bool used_cache' and documented it.
305 (TypeManager.MemberLookup): If we already used the cache in the first
306 iteration, we don't need to do the interfaces check.
308 2002-08-19 Martin Baulig <martin@gnome.org>
310 * decl.cs (DeclSpace.FindMembers): New abstract method. Moved this
311 here from IMemberFinder and don't implement this interface anymore.
312 (DeclSpace.MemberCache): Moved here from IMemberFinder.
314 * typemanager.cs (IMemberFinder): This interface is now only used by
315 classes which actually support the member cache.
316 (TypeManager.builder_to_member_finder): Renamed to builder_to_declspace
317 since we only put DeclSpaces into this Hashtable.
318 (MemberLookup_FindMembers): Use `builder_to_declspace' if the type is
319 a dynamic type and TypeHandle.GetTypeHandle() otherwise.
321 2002-08-16 Martin Baulig <martin@gnome.org>
323 * typemanager.cs (ICachingMemberFinder): Removed.
324 (IMemberFinder.MemberCache): New property.
325 (TypeManager.FindMembers): Merged this with RealFindMembers().
326 This function will never be called from TypeManager.MemberLookup()
327 so we can't use the cache here, just the IMemberFinder.
328 (TypeManager.MemberLookup_FindMembers): Check whether the
329 IMemberFinder has a MemberCache and call the cache's FindMembers
331 (MemberCache): Rewrote larger parts of this yet another time and
334 2002-08-15 Miguel de Icaza <miguel@ximian.com>
336 * driver.cs (LoadArgs): Support quoting.
338 (Usage): Show the CSC-like command line arguments.
340 Improved a few error messages.
342 2002-08-15 Martin Baulig <martin@gnome.org>
344 * typemanager.cs (IMemberContainer.Type): New property.
345 (IMemberContainer.IsInterface): New property.
347 The following changes are conditional to BROKEN_RUNTIME, which is
348 defined at the top of the file.
350 * typemanager.cs (MemberCache.MemberCache): Don't add the base
351 class'es members, but add all members from TypeHandle.ObjectType
352 if we're an interface.
353 (MemberCache.AddMembers): Set the Declared flag if member.DeclaringType
355 (MemberCache.CacheEntry.Container): Removed this field.
356 (TypeHandle.GetMembers): Include inherited members.
358 2002-08-14 Gonzalo Paniagua Javier <gonzalo@ximian.com>
360 * typemanager.cs: fixed compilation and added a comment on a field that
363 2002-08-15 Martin Baulig <martin@gnome.org>
365 * class.cs (ConstructorInitializer.Resolve): In the
366 Expression.MemberLookup call, use the queried_type as
369 * typemanager.cs (IMemberContainer.GetMembers): Removed the `bool
370 declared' attribute, it's always true.
371 (IMemberContainer.Parent, IMemberContainer.Name): New properties.
372 (TypeManager.MemberLookup_FindMembers): [FIXME FIXME FIXME] Added
373 temporary wrapper for FindMembers which tells MemberLookup whether
374 members from the base classes are included in the return value.
375 This will go away soon.
376 (TypeManager.MemberLookup): Use this temporary hack here; once the
377 new MemberCache is completed, we don't need to do the DeclaredOnly
378 looping here anymore since the MemberCache will take care of this.
379 (TypeManager.IsSubclassOrNestedChildOf): Allow `type == parent'.
380 (MemberCache): When creating the MemberCache for a class, get
381 members from the current class and all its base classes.
382 (MemberCache.CacheEntry.Container): New field. This is a
383 temporary hack until the Mono runtime is fixed to distinguish
384 between ReflectedType and DeclaringType. It allows us to use MCS
385 with both the MS runtime and the unfixed Mono runtime without
386 problems and without accecting performance.
387 (MemberCache.SearchMembers): The DeclaredOnly looping from
388 TypeManager.MemberLookup is now done here.
390 2002-08-14 Martin Baulig <martin@gnome.org>
392 * statement.cs (MyStructInfo.MyStructInfo): Don't call
393 Type.GetFields on dynamic types but get the fields from the
394 corresponding TypeContainer.
395 (MyStructInfo.GetStructInfo): Added check for enum types.
397 * typemanager.cs (MemberList.IsSynchronized): Implemented.
398 (MemberList.SyncRoot): Implemented.
399 (TypeManager.FilterWithClosure): No need to check permissions if
400 closure_start_type == closure_invocation_type, don't crash if
401 closure_invocation_type is null.
403 2002-08-13 Martin Baulig <martin@gnome.org>
405 Rewrote TypeContainer.FindMembers to use a member cache. This
406 gives us a speed increase of about 35% for the self-hosting MCS
407 build and of about 15-20% for the class libs (both on GNU/Linux).
409 * report.cs (Timer): New class to get enhanced profiling. This
410 whole class is "TIMER" conditional since it remarkably slows down
413 * class.cs (MemberList): New class. This is an IList wrapper
414 which we're now using instead of passing MemberInfo[]'s around to
415 avoid copying this array unnecessarily.
416 (IMemberFinder.FindMember): Return a MemberList, not a MemberInfo [].
417 (ICachingMemberFinder, IMemberContainer): New interface.
418 (TypeManager.FilterWithClosure): If `criteria' is null, the name
419 has already been checked, otherwise use it for the name comparision.
420 (TypeManager.FindMembers): Renamed to RealMemberFinder and
421 provided wrapper which tries to use ICachingMemberFinder.FindMembers
422 if possible. Returns a MemberList, not a MemberInfo [].
423 (TypeHandle): New class, implements IMemberContainer. We create
424 one instance of this class per type, it contains a MemberCache
425 which is used to do the member lookups.
426 (MemberCache): New class. Each instance of this class contains
427 all members of a type and a name-based hash table.
428 (MemberCache.FindMembers): This is our new member lookup
429 function. First, it looks up all members of the requested name in
430 the hash table. Then, it walks this list and sorts out all
431 applicable members and returns them.
433 2002-08-13 Martin Baulig <martin@gnome.org>
435 In addition to a nice code cleanup, this gives us a performance
436 increase of about 1.4% on GNU/Linux - not much, but it's already
437 half a second for the self-hosting MCS compilation.
439 * typemanager.cs (IMemberFinder): New interface. It is used by
440 TypeManager.FindMembers to call FindMembers on a TypeContainer,
441 Enum, Delegate or Interface.
442 (TypeManager.finder_to_member_finder): New PtrHashtable.
443 (TypeManager.finder_to_container): Removed.
444 (TypeManager.finder_to_delegate): Removed.
445 (TypeManager.finder_to_interface): Removed.
446 (TypeManager.finder_to_enum): Removed.
448 * interface.cs (Interface): Implement IMemberFinder.
450 * delegate.cs (Delegate): Implement IMemberFinder.
452 * enum.cs (Enum): Implement IMemberFinder.
454 * class.cs (TypeContainer): Implement IMemberFinder.
456 2002-08-12 Martin Baulig <martin@gnome.org>
458 * ecore.cs (TypeExpr.DoResolveType): Mark this as virtual.
460 2002-08-12 Martin Baulig <martin@gnome.org>
462 * ecore.cs (ITypeExpression): New interface for expressions which
464 (TypeExpression): Renamed to TypeLookupExpression.
465 (Expression.DoResolve): If we're doing a types-only lookup, the
466 expression must implement the ITypeExpression interface and we
467 call DoResolveType() on it.
468 (SimpleName): Implement the new ITypeExpression interface.
469 (SimpleName.SimpleNameResolve): Removed the ec.OnlyLookupTypes
470 hack, the situation that we're only looking up types can't happen
471 anymore when this method is called. Moved the type lookup code to
472 DoResolveType() and call it.
473 (SimpleName.DoResolveType): This ITypeExpression interface method
474 is now doing the types-only lookup.
475 (TypeExpr, TypeLookupExpression): Implement ITypeExpression.
476 (ResolveFlags): Added MaskExprClass.
478 * expression.cs (MemberAccess): Implement the ITypeExpression
480 (MemberAccess.DoResolve): Added support for a types-only lookup
481 when we're called via ITypeExpression.DoResolveType().
482 (ComposedCast): Implement the ITypeExpression interface.
484 * codegen.cs (EmitContext.OnlyLookupTypes): Removed. Call
485 Expression.Resolve() with ResolveFlags.Type instead.
487 2002-08-12 Martin Baulig <martin@gnome.org>
489 * interface.cs (Interface.Define): Apply attributes.
491 * attribute.cs (Attribute.ApplyAttributes): Added support for
492 interface attributes.
494 2002-08-11 Martin Baulig <martin@gnome.org>
496 * statement.cs (Block.Emit): Only check the "this" variable if we
497 do not always throw an exception.
499 * ecore.cs (PropertyExpr.DoResolveLValue): Implemented, check
500 whether the property has a set accessor.
502 2002-08-11 Martin Baulig <martin@gnome.org>
504 Added control flow analysis support for structs.
506 * ecore.cs (ResolveFlags): Added `DisableFlowAnalysis' to resolve
507 with control flow analysis turned off.
508 (IVariable): New interface.
509 (SimpleName.SimpleNameResolve): If MemberAccess.ResolveMemberAccess
510 returns an IMemberExpr, call DoResolve/DoResolveLValue on it.
511 (FieldExpr.DoResolve): Resolve the instance expression with flow
512 analysis turned off and do the definite assignment check after the
513 resolving when we know what the expression will resolve to.
515 * expression.cs (LocalVariableReference, ParameterReference):
516 Implement the new IVariable interface, only call the flow analysis
517 code if ec.DoFlowAnalysis is true.
518 (This): Added constructor which takes a Block argument. Implement
519 the new IVariable interface.
520 (MemberAccess.DoResolve, MemberAccess.DoResolveLValue): Call
521 DoResolve/DoResolveLValue on the result of ResolveMemberLookup().
522 This does the definite assignment checks for struct members.
524 * class.cs (Constructor.Emit): If this is a non-static `struct'
525 constructor which doesn't have any initializer, call
526 Block.AddThisVariable() to tell the flow analysis code that all
527 struct elements must be initialized before control returns from
530 * statement.cs (MyStructInfo): New public class.
531 (UsageVector.this [VariableInfo vi]): Added `int field_idx'
532 argument to this indexer. If non-zero, check an individual struct
533 member, not the whole struct.
534 (FlowBranching.CheckOutParameters): Check struct members.
535 (FlowBranching.IsVariableAssigned, SetVariableAssigned): Added
536 overloaded versions of these methods which take an additional
537 `int field_idx' argument to check struct members.
538 (FlowBranching.IsParameterAssigned, SetParameterAssigned): Added
539 overloaded versions of these methods which take an additional
540 `string field_name' argument to check struct member.s
541 (VariableInfo): Implement the IVariable interface.
542 (VariableInfo.StructInfo): New public property. Returns the
543 MyStructInfo instance of the variable if it's a struct or null.
544 (Block.AddThisVariable): New public method. This is called from
545 Constructor.Emit() for non-static `struct' constructor which do
546 not have any initializer. It creates a special variable for the
547 "this" instance variable which will be checked by the flow
548 analysis code to ensure that all of the struct's fields are
549 initialized before control returns from the constructor.
550 (UsageVector): Added support for struct members. If a
551 variable/parameter is a struct with N members, we reserve a slot
552 in the usage vector for each member. A struct is considered fully
553 initialized if either the struct itself (slot 0) or all its
554 members are initialized.
556 2002-08-08 Martin Baulig <martin@gnome.org>
558 * driver.cs (Driver.MainDriver): Only report an error CS5001
559 if there were no compilation errors.
561 * codegen.cs (EmitContext.EmitContext): Use the DeclSpace's
562 `UnsafeContext' property to determine whether the parent is in
563 unsafe context rather than checking the parent's ModFlags:
564 classes nested in an unsafe class are unsafe as well.
566 2002-08-08 Martin Baulig <martin@gnome.org>
568 * statement.cs (UsageVector.MergeChildren): Distinguish between
569 `Breaks' and `Returns' everywhere, don't set `Breaks' anymore if
570 we return. Added test17() and test18() to test-154.cs.
572 2002-08-08 Martin Baulig <martin@gnome.org>
574 * typemanager.cs (TypeManager.FilterWithClosure): If we have
575 Family access, make sure the invoking type isn't a subclass of the
576 queried type (that'd be a CS1540).
578 * ecore.cs (Expression.MemberLookup): Added overloaded version of
579 this method which takes an additional `Type invocation_type'.
581 * expression.cs (BaseAccess.DoResolve): Use the base type as
582 invocation and query type.
583 (MemberAccess.DoResolve): If the lookup failed and we're about to
584 report a CS0122, try a lookup with the ec.ContainerType - if this
585 succeeds, we must report a CS1540.
587 2002-08-08 Martin Baulig <martin@gnome.org>
589 * ecore.cs (IMemberExpr): Added `bool IsInstance' property.
590 (MethodGroupExpr): Implement the IMemberExpr interface.
592 * expression (MemberAccess.ResolveMemberAccess): No need to have
593 any special code for MethodGroupExprs anymore, they're now
596 2002-08-08 Martin Baulig <martin@gnome.org>
598 * typemanager.cs (TypeManager.FilterWithClosure): Check Assembly,
599 Family, FamANDAssem and FamORAssem permissions.
600 (TypeManager.IsSubclassOrNestedChildOf): New public method.

612 2002-08-07 Martin Baulig <martin@gnome.org>
614 * class.cs (FieldBase.Initializer): Renamed to `init' and made private.
615 (FieldBase.HasFieldInitializer): New public property.
616 (FieldBase.GetInitializerExpression): New public method. Resolves and
617 returns the field initializer and makes sure it is only resolved once.
618 (TypeContainer.EmitFieldInitializers): Call
619 FieldBase.GetInitializerExpression to get the initializer, this ensures
620 that it isn't resolved multiple times.
622 * codegen.cs (EmitContext): Added `bool IsFieldInitialier'. This tells
623 the resolving process (SimpleName/MemberLookup) that we're currently
624 emitting a field initializer (which must not access any instance members,
625 this is an error CS0236).
627 * ecore.cs (SimpleName.Error_ObjectRefRequired): Added EmitContext
628 argument, if the `IsFieldInitializer' flag is set, we must report and
629 error CS0236 and not an error CS0120.
631 2002-08-07 Martin Baulig <martin@gnome.org>
633 * ecore.cs (IMemberExpr): New public interface.
634 (FieldExpr, PropertyExpr, EventExpr): Implement IMemberExpr.
635 (SimpleName.SimpleNameResolve): Call MemberAccess.ResolveMemberAccess
636 if the expression is an IMemberExpr.
638 * expression.cs (MemberAccess.ResolveMemberAccess): Allow `left'
639 to be null, implicitly default to `this' if we're non-static in
640 this case. Simplified the code a lot by using the new IMemberExpr
641 interface. Also fixed bug #28176 here.
643 2002-08-06 Martin Baulig <martin@gnome.org>
645 * cs-parser.jay (SimpleLookup): Removed. We need to create
646 ParameterReferences during semantic analysis so that we can do a
647 type-only search when resolving Cast, TypeOf and SizeOf.
648 (block): Pass the `current_local_parameters' to the Block's
651 * class.cs (ConstructorInitializer): Added `Parameters parameters'
652 argument to the constructor.
653 (ConstructorInitializer.Resolve): Create a temporary implicit
654 block with the parameters.
656 * ecore.cs (SimpleName.SimpleNameResolve): Resolve parameter
657 references here if we aren't doing a type-only search.
659 * statement.cs (Block): Added constructor which takes a
660 `Parameters parameters' argument.
661 (Block.Parameters): New public property.
663 * support.cs (InternalParameters.Parameters): Renamed `parameters'
664 to `Parameters' and made it public readonly.
666 2002-08-06 Martin Baulig <martin@gnome.org>
668 * ecore.cs (Expression.Warning): Made this public as well.
670 * report.cs (Report.Debug): Print the contents of collections.
672 2002-08-06 Martin Baulig <martin@gnome.org>
674 * ecore.cs (Expression.ResolveFlags): New [Flags] enum. This is
675 used to tell Resolve() which kinds of expressions it may return.
676 (Expression.Resolve): Added overloaded version of this method which
677 takes a `ResolveFlags flags' argument. This can be used to tell
678 Resolve() which kinds of expressions it may return. Reports a
680 (Expression.ResolveWithSimpleName): Removed, use Resolve() with
681 ResolveFlags.SimpleName.
682 (Expression.Error118): Added overloaded version of this method which
683 takes a `ResolveFlags flags' argument. It uses the flags to determine
684 which kinds of expressions are allowed.
686 * expression.cs (Argument.ResolveMethodGroup): New public method.
687 Resolves an argument, but allows a MethodGroup to be returned.
688 This is used when invoking a delegate.
690 * TODO: Updated a bit.
692 2002-08-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
694 Fixed compilation with csc.
696 * ecore.cs: Expression.Error made public. Is this correct? Should
697 Warning be made public too?
699 * expression.cs: use ea.Location instead of ea.loc.
700 [FIXME: Filed as bug #28607: MCS must report these errors.]
702 2002-08-06 Martin Baulig <martin@gnome.org>
704 * ecore.cs (Expression.loc): Moved the location here instead of
705 duplicating it in all derived classes.
706 (Expression.Location): New public property.
707 (Expression.Error, Expression.Warning): Made them non-static and
708 removed the location argument.
709 (Expression.Warning): Added overloaded version which takes an
710 `int level' argument.
711 (Expression.Error118): Make this non-static and removed the
712 expression and location arguments.
713 (TypeExpr): Added location argument to the constructor.
715 * expression.cs (StaticCallExpr): Added location argument to
717 (Indirection, PointerArithmetic): Likewise.
718 (CheckedExpr, UnCheckedExpr): Likewise.
719 (ArrayAccess, IndexerAccess, UserCast, ArrayPtr): Likewise.
720 (StringPtr): Likewise.
723 2002-08-05 Martin Baulig <martin@gnome.org>
725 * expression.cs (BaseAccess.DoResolve): Actually report errors.
727 * assign.cs (Assign.DoResolve): Check whether the source
728 expression is a value or variable.
730 * statement.cs (Try.Resolve): Set ec.InTry/InCatch/InFinally
731 while resolving the corresponding blocks.
733 * interface.cs (Interface.GetInterfaceTypeByName): Actually report
734 an error, don't silently return null.
736 * statement.cs (Block.AddVariable): Do the error reporting here
737 and distinguish between CS0128 and CS0136.
738 (Block.DoResolve): Report all unused labels (warning CS0164).
739 (LabeledStatement): Pass the location to the constructor.
740 (LabeledStatement.HasBeenReferenced): New property.
741 (LabeledStatement.Resolve): Set it to true here.
743 * statement.cs (Return.Emit): Return success even after reporting
744 a type mismatch error (CS0126 or CS0127), this is what csc does and
745 it avoids confusing the users with any consecutive errors.
747 2002-08-05 Martin Baulig <martin@gnome.org>
749 * enum.cs (Enum.LookupEnumValue): Catch circular definitions.
751 * const.cs (Const.LookupConstantValue): Catch circular definitions.
753 * expression.cs (MemberAccess.DoResolve): Silently return if an
754 error has already been reported.
756 * ecore.cs (Expression.MemberLookupFinal): Silently return if an
757 error has already been reported.
759 2002-08-05 Martin Baulig <martin@gnome.org>

762 vector if we actually have any "out" parameters.
764 2002-08-05 Martin Baulig <martin@gnome.org>
766 * expression.cs (Binary.ResolveOperator): When combining delegates,
767 they must have the same type.
769 2002-08-05 Martin Baulig <martin@gnome.org>
771 * typemanager.cs (TypeManager.GetArgumentTypes): Don't call
772 PropertyInfo.GetIndexParameters() on dynamic types, this doesn't
773 work with the ms runtime and we also don't need it: if we're a
774 PropertyBuilder and not in the `indexer_arguments' hash, then we
775 are a property and not an indexer.
777 * class.cs (TypeContainer.AsAccessible): Use Type.IsArray,
778 Type.IsPointer and Type.IsByRef instead of Type.HasElementType
779 since the latter one doesn't work with the ms runtime.
781 2002-08-03 Martin Baulig <martin@gnome.org>
783 Fixed bugs #27998 and #22735.
785 * class.cs (Method.IsOperator): New public field.
786 (Method.CheckBase): Report CS0111 if there's already a method
787 with the same parameters in the current class. Report CS0508 when
788 attempting to change the return type of an inherited method.
789 (MethodData.Emit): Report CS0179 if a method doesn't have a body
790 and it's not marked abstract or extern.
791 (PropertyBase): New abstract base class for Property and Indexer.
792 (PropertyBase.CheckBase): Moved here from Property and made it work
794 (PropertyBase.Emit): Moved here from Property.Emit, Indexer.Emit is
795 the same so we can reuse it there.
796 (Property, Indexer): Derive from PropertyBase.
797 (MethodSignature.inheritable_property_signature_filter): New delegate
798 to find properties and indexers.
800 * decl.cs (MemberCore.CheckMethodAgainstBase): Added `string name'
801 argument and improved error reporting.
803 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): Renamed to
804 EmptyReadOnlyParameters and made it a property.
806 * typemanager.cs (TypeManager.GetArgumentTypes): Added overloaded
807 version of this method which takes a `PropertyInfo indexer'.
808 (TypeManager.RegisterIndexer): New method.
810 * class.cs: Added myself as author of this file :-)
812 2002-08-03 Gonzalo Paniagua Javier <gonzalo@ximian.com>

824 (MemberBase.CheckParameters): Report errors if the accessibility
827 * delegate.cs (Delegate.Delegate): The default visibility is
828 internal for top-level types and private for nested types.
829 (Delegate.Define): Report errors if the accessibility checks fail.
831 * enum.cs (Enum.Enum): The default visibility is internal for
832 top-level types and private for nested types.
833 (Enum.DefineType): Compute the correct visibility.
835 * modifiers.cs (Modifiers.TypeAttr): Added a version of this
836 function which takes a `bool is_toplevel' instead of a TypeContainer.
838 * typemanager.cs (TypeManager.IsBuiltinType): `void' is also a
841 2002-08-02 Martin Baulig <martin@gnome.org>
843 * expression.cs (LocalVariableReferenc): Added constructor which
844 takes additional `VariableInfo vi' and `bool is_readonly' arguments.
845 (LocalVariableReference.IsReadOnly): New property.
846 (LocalVariableReference.DoResolveLValue): Report a CS1604 if the
847 variable is readonly, use our own readonly flag to do this; you can
848 use the new constructor to get a writable reference to a read-only
851 * cs-parser.jay (foreach_statement, using_statement): Get a writable
852 reference to the local variable.
854 2002-08-01 Miguel de Icaza <miguel@ximian.com>
856 * rootcontext.cs (ResolveCore): Also include System.Exception
858 * statement.cs (Block.Emit): Do not emit the dead-code warnings if
859 we reach an EmptyStatement.

884 `hm.is_disposable' if we're using the collection pattern.
885 (Foreach.EmitCollectionForeach): Use the correct type for the

897 (Catch.Resolve): New method. Do the type lookup here and check
898 whether it derives from System.Exception (CS0155).
899 (Catch.CatchType, Catch.IsGeneral): New public properties.
901 * typemanager.cs (TypeManager.exception_type): Added.
903 2002-07-31 Miguel de Icaza <miguel@ximian.com>

1072 (MemberBase): Moved everything which was specific to a single
1073 accessor/method to MethodData.
1074 (Method): Create a new MethodData and call Define() and Emit() on it.
1075 (Property, Indexer, Event): Create a new MethodData objects for each
1076 accessor and call Define() and Emit() on them.
1078 2002-07-25 Martin Baulig <martin@gnome.org>
1080 Made MethodCore derive from MemberBase to reuse the code from there.
1081 MemberBase now also checks for attributes.

1084 (MemberBase.GetMethodFlags): Moved here from class Method and marked
1086 (MemberBase.DefineAccessor): Renamed to DefineMethod(), added

1107 ensure that abstract and external accessors don't declare a body.
1109 * attribute.cs (Attribute.GetValidPieces): Make this actually work:
1110 `System.Attribute.GetCustomAttributes (attr.Type)' does a recursive
1111 lookup in the attribute's parent classes, so we need to abort as soon
1112 as we found the first match.
1113 (Attribute.Obsolete_GetObsoleteMessage): Return the empty string if
1114 the attribute has no arguments.
1116 * typemanager.cs (TypeManager.AddMethod): Now takes a MemberBase instead

1146 if we're overriding a virtual function, set the new private variable
1147 `parent_method'; call the new TypeManager.AddMethod().
1149 * typemanager.cs (TypeManager.AddMethod): New static method. Stores
1150 the MethodBuilder and the Method in a PtrHashtable.
1151 (TypeManager.builder_to_method): Added for this purpose.
1152 (TypeManager.MethodFlags): Added IsObsoleteError.
1153 (TypeManager.GetMethodFlags): Added `Location loc' argument. Lookup

1158 2002-07-24 Martin Baulig <martin@gnome.org>
1160 * cs-tokenizer.cs: Eat up trailing whitespaces and one-line comments in
1161 preprocessor directives, ensure that the argument to #define/#undef is
1162 exactly one identifier and that it's actually an identifier.
1164 Some weeks ago I did a `#define DEBUG 1' myself and wondered why this
1167 2002-07-24 Martin Baulig <martin@gnome.org>
1169 * statement.cs (Foreach.ForeachHelperMethods): Added `Type element_type',
1170 initialize it to TypeManager.object_type in the constructor.
1171 (Foreach.GetEnumeratorFilter): Set `hm.element_type' to the return type
1172 of the `hm.get_current' method if we're using the collection pattern.
1173 (Foreach.EmitCollectionForeach): Use `hm.element_type' as the source type
1174 for the explicit conversion to make it work when we're using the collection
1175 pattern and the `Current' property has a different return type than `object'.
1178 2002-07-24 Martin Baulig <martin@gnome.org>
1180 * delegate.cs (Delegate.VerifyMethod): Simply return null if the method
1181 does not match, but don't report any errors. This method is called in
1182 order for all methods in a MethodGroupExpr until a matching method is
1183 found, so we don't want to bail out if the first method doesn't match.
1184 (NewDelegate.DoResolve): If none of the methods in the MethodGroupExpr
1185 matches, report the 123. Fixes #28070.
1187 2002-07-24 Martin Baulig <martin@gnome.org>
1189 * expression.cs (ArrayAccess.EmitStoreOpcode): Moved the
1190 TypeManager.TypeToCoreType() to the top of the method so the
1191 following equality checks will work. Fixes #28107.
1193 2002-07-24 Martin Baulig <martin@gnome.org>
1195 * cfold.cs (ConstantFold.DoConstantNumericPromotions): "If either
1196 operand is of type uint, and the other operand is of type sbyte,
1197 short or int, the operands are converted to type long." -
1198 Actually do what this comment already told us. Fixes bug #28106,
1201 2002-07-24 Martin Baulig <martin@gnome.org>
1203 * class.cs (MethodBase): New abstract class. This is now a base
1204 class for Property, Indexer and Event to avoid some code duplication
1205 in their Define() and DefineMethods() methods.
1206 (MethodBase.DoDefine, MethodBase.DefineAccessor): Provide virtual
1207 generic methods for Define() and DefineMethods().
1208 (FieldBase): Derive from MemberBase, not MemberCore.
1209 (Property): Derive from MemberBase, not MemberCore.
1210 (Property.DefineMethod): Moved all the code from this method to the
1211 new MethodBase.DefineAccessor(), just call it with appropriate
1213 (Property.Define): Call the new Property.DoDefine(), this does some
1214 sanity checks and we don't need to duplicate the code everywhere.
1215 (Event): Derive from MemberBase, not MemberCore.
1216 (Event.Define): Use the new MethodBase.DefineAccessor() to define the
1217 accessors, this will also make them work with interface events.
1218 (Indexer): Derive from MemberBase, not MemberCore.
1219 (Indexer.DefineMethod): Removed, call MethodBase.DefineAccessor() insstead.
1220 (Indexer.Define): Use the new MethodBase functions.
1222 * interface.cs (InterfaceEvent.InterfaceEvent): Added `Location loc'
1223 argument to the constructor.
1224 (Interface.FindMembers): Added support for interface events.
1225 (Interface.PopluateEvent): Implemented.
1227 Added test-149.cs for this. This also fixes bugs #26067 and #24256.
1229 2002-07-22 Miguel de Icaza <miguel@ximian.com>
1231 * class.cs (TypeContainer.AddMethod): Adding methods do not use IsValid,
1232 but this is required to check for a method name being the same as
1233 the containing class.
1237 2002-07-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1239 * interface.cs: initialize variable.
1241 2002-07-23 Martin Baulig <martin@gnome.org>
1243 Implemented the IndexerName attribute in interfaces.
1245 * class.cs (TypeContainer.DefineIndexers): Don't set the indexer
1246 name if this is an explicit interface implementation.
1247 (Indexer.InterfaceIndexerName): New public variable. If we're
1248 implementing an interface indexer, this is the IndexerName in that
1249 interface. Otherwise, it's the IndexerName.
1250 (Indexer.DefineMethod): If we're implementing interface indexer,
1251 set InterfaceIndexerName. Use the new Pending.IsInterfaceIndexer
1252 and Pending.ImplementIndexer methods.
1253 (Indexer.Define): Also define the PropertyBuilder if we're
1254 implementing an interface indexer and this is neither an explicit
1255 interface implementation nor do the IndexerName match the one in
1258 * pending.cs (TypeAndMethods): Added `MethodInfo [] need_proxy'.
1259 If a method is defined here, then we always need to create a proxy
1260 for it. This is used when implementing interface indexers.
1261 (Pending.IsInterfaceIndexer): New public method.
1262 (Pending.ImplementIndexer): New public method.
1263 (Pending.InterfaceMethod): Added `MethodInfo need_proxy' argument.
1264 This is used when implementing interface indexers to define a proxy
1266 (Pending.VerifyPendingMethods): Look in the `need_proxy' array and
1267 define a proxy if necessary.
1269 * interface.cs (Interface.IndexerName): New public variable.
1270 (Interface.PopulateIndexer): Set the IndexerName.
1271 (Interface.DefineIndexers): New private method. Populate all the
1272 indexers and make sure their IndexerNames match.
1274 * typemanager.cs (IndexerPropertyName): Added support for interface
1277 2002-07-22 Martin Baulig <martin@gnome.org>
1279 * codegen.cs (EmitContext.HasReturnLabel): New public variable.
1280 (EmitContext.EmitTopBlock): Always mark the ReturnLabel and emit a
1281 ret if HasReturnLabel.
1282 (EmitContext.TryCatchLevel, LoopBeginTryCatchLevel): New public
1285 * statement.cs (Do.Emit, While.Emit, For.Emit, Foreach.Emit): Save
1286 and set the ec.LoopBeginTryCatchLevel.
1287 (Try.Emit): Increment the ec.TryCatchLevel while emitting the block.
1288 (Continue.Emit): If the ec.LoopBeginTryCatchLevel is smaller than
1289 the current ec.TryCatchLevel, the branch goes out of an exception
1290 block. In this case, we need to use Leave and not Br.
1292 2002-07-22 Martin Baulig <martin@gnome.org>
1294 * statement.cs (Try.Emit): Emit an explicit ret after the end of the
1295 block unless the block does not always return or it is contained in
1296 another try { ... } catch { ... } block. Fixes bug #26506.
1297 Added verify-1.cs to the test suite.
1299 2002-07-22 Martin Baulig <martin@gnome.org>
1301 * statement.cs (Switch.TableSwitchEmit): If we don't have a default,
1302 then we do not always return. Fixes bug #24985.
1304 2002-07-22 Martin Baulig <martin@gnome.org>
1306 * expression.cs (Invocation.OverloadedResolve): Do the BetterFunction()
1307 lookup on a per-class level; ie. walk up the class hierarchy until we
1308 found at least one applicable method, then choose the best among them.
1309 Fixes bug #24463 and test-29.cs.
1311 2002-07-22 Martin Baulig <martin@gnome.org>
1313 * typemanager.cs (TypeManager.ArrayContainsMethod): Don't check the
1314 return types of the methods. The return type is not part of the
1315 signature and we must not check it to make the `new' modifier work.
1316 Fixes bug #27999, also added test-147.cs.
1317 (TypeManager.TypeToCoreType): Added TypeManager.type_type.
1319 * expression.cs (Invocation.DoResolve): Call TypeManager.TypeToCoreType()
1320 on the method's return type.
1322 2002-07-21 Martin Baulig <martin@gnome.org>
1324 * assign.cs: Make this work if the rightmost source is a constant and
1325 we need to do an implicit type conversion. Also adding a few more tests
1326 to test-38.cs which should have caught this.
1328 * makefile.gnu: Disable debugging, there's already the mcs-mono2.exe
1329 target in the makefile for this. The makefile.gnu is primarily intended
1330 for end-users who don't want to debug the compiler.
1332 2002-07-21 Martin Baulig <martin@gnome.org>
1334 * assign.cs: Improved the Assign class so it can now handle embedded
1335 assignments (X = Y = Z = something). As a side-effect this'll now also
1336 consume less local variables. test-38.cs now passes with MCS, added
1337 a few new test cases to that test.
1339 2002-07-20 Martin Baulig <martin@gnome.org>
1341 * expression.cs (Binary.EmitBranchable): Emit correct unsigned branch
1342 instructions. Fixes bug #27977, also added test-146.cs.
1344 2002-07-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1346 * cs-tokenizer.cs: fixed getHex ().
1348 2002-07-19 Martin Baulig <martin@gnome.org>
1350 * expression.cs (Invocation.EmitParams): Use TypeManager.LookupType(),
1351 not Type.GetType() to lookup the array type. This is needed when
1352 we're constructing an array of a user-defined type.
1353 (ArrayAccess.EmitDynamicInitializers): Only emit the Ldelema for
1354 single-dimensional arrays, but also for single-dimensial arrays of
1357 2002-07-19 Martin Baulig <martin@gnome.org>
1359 * expression.cs (New.DoEmit): Create a new LocalTemporary each time
1360 this function is called, it's not allowed to share LocalBuilders
1363 2002-07-19 Martin Baulig <martin@gnome.org>
1365 * expression.cs (Argument.Resolve): Report an error 118 when trying
1366 to pass a type as argument.
1368 2002-07-18 Martin Baulig <martin@gnome.org>
1370 * ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
1371 Conv_R_Un for the signed `long' type.
1373 2002-07-15 Miguel de Icaza <miguel@ximian.com>
1375 * expression.cs (MemberAccess.DoResolve): Do not reuse the field
1376 `expr' for the temporary result, as that will fail if we do
1377 multiple resolves on the same expression.
1379 2002-07-05 Miguel de Icaza <miguel@ximian.com>
1381 * ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
1382 ec.TypeContainer for looking up aliases.
1384 * class.cs (TypeContainer): Remove LookupAlias from here.
1386 * decl.cs (DeclSpace); Move here.
1388 2002-07-01 Miguel de Icaza <miguel@ximian.com>
1390 * class.cs (FindMembers): Only call filter if the constructor
1391 bulider is not null.
1393 Also handle delegates in `NestedTypes' now. Now we will perform
1394 type lookups using the standard resolution process. This also
1397 * decl.cs (DeclSpace.ResolveType): New type resolution routine.
1398 This uses Expressions (the limited kind that can be parsed by the
1399 tree) instead of strings.
1401 * expression.cs (ComposedCast.ToString): Implement, used to flag
1402 errors since now we have to render expressions.
1404 (ArrayCreation): Kill FormElementType. Use ComposedCasts in
1407 * ecore.cs (SimpleName.ToString): ditto.
1409 * cs-parser.jay: Instead of using strings to assemble types, use
1410 Expressions to assemble the type (using SimpleName, ComposedCast,
1411 MemberAccess). This should fix the type lookups in declarations,
1412 because we were using a different code path for this.
1414 * statement.cs (Block.Resolve): Continue processing statements
1415 even when there is an error.
1417 2002-07-17 Miguel de Icaza <miguel@ximian.com>
1419 * class.cs (Event.Define): Also remove the `remove' method from
1420 the list of pending items.
1422 * expression.cs (ParameterReference): Use ldarg.N (0..3) to
1423 generate more compact code.
1425 2002-07-17 Martin Baulig <martin@gnome.org>
1427 * const.cs (Const.LookupConstantValue): Add support for constant
1428 `unchecked' and `checked' expressions.
1429 Also adding test case test-140.cs for this.
1431 2002-07-17 Martin Baulig <martin@gnome.org>
1433 * statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
1434 check whether mi.ReturnType implements the IEnumerator interface; the
1435 `==' and the IsAssignableFrom() will fail in this situation.
1437 2002-07-16 Ravi Pratap <ravi@ximian.com>
1439 * ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix
1442 2002-07-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1444 * expression.cs: fixed bug #27811.
1446 2002-07-14 Miguel de Icaza <miguel@ximian.com>
1448 * expression.cs (ParameterReference.AddressOf): Patch from Paolo
1449 Molaro: when we are a ref, the value already contains a pointer
1450 value, do not take the address of it.
1452 2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1453 * removed mb-parser.jay and mb-tokenizer.cs
1455 Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
1457 * expression.cs: check against the building corlib void type.
1459 Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
1461 * ecore.cs: fix for valuetype static readonly fields: when
1462 initializing them, we need their address, not the address of a copy.
1464 Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
1466 * typemanager.cs: register also enum_type in corlib.
1468 Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
1470 * class.cs: allow calling this (but not base) initializers in structs.
1472 Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
1474 * ecore.cs: make sure we compare against the building base types
1477 Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
1479 * typemanager.cs: fix TypeToCoreType() to handle void and object
1480 (corlib gets no more typerefs after this change).
1482 2002-07-12 Miguel de Icaza <miguel@ximian.com>
1484 * expression.cs (ArrayCreation.EmitArrayArguments): use
1485 Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
1487 (ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
1488 Conv_Ovf_I_Un for the array arguments. Even if C# allows longs as
1489 array indexes, the runtime actually forbids them.
1491 * ecore.cs (ExpressionToArrayArgument): Move the conversion code
1492 for array arguments here.
1494 * expression.cs (EmitLoadOpcode): System.Char is a U2, use that
1495 instead of the default for ValueTypes.
1497 (New.DoEmit): Use IsValueType instead of
1498 IsSubclassOf (value_type)
1499 (New.DoResolve): ditto.
1500 (Invocation.EmitCall): ditto.
1502 * assign.cs (Assign): ditto.
1504 * statement.cs (Unsafe): Ok, so I got the semantics wrong.
1505 Statements *are* currently doing part of their resolution during
1508 Expressions do always resolve during resolve, but statements are
1509 only required to propagate resolution to their children.
1511 2002-07-11 Miguel de Icaza <miguel@ximian.com>
1513 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
1515 (LoadAssembly): Do not add the dll if it is already specified
1517 (MainDriver): Add the System directory to the link path at the end,
1518 after all the other -L arguments.
1520 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
1521 wrong opcode for loading bytes and bools (ldelem.i1 instead of
1522 ldelem.u1) and using the opposite for sbytes.
1524 This fixes Digger, and we can finally run it.
1526 * driver.cs (UnixParseOption): Move the option parsing here.
1527 (CSCParseOption): Implement CSC-like parsing of options.
1529 We now support both modes of operation, the old Unix way, and the
1530 new CSC-like way. This should help those who wanted to make cross
1533 The only thing broken is that /r:, /reference: and /lib: are not
1534 implemented, because I want to make those have the same semantics
1535 as the CSC compiler has, and kill once and for all the confussion
1536 around this. Will be doing this tomorrow.
1538 * statement.cs (Unsafe.Resolve): The state is checked during
1539 resolve, not emit, so we have to set the flags for IsUnsfe here.
1541 2002-07-10 Miguel de Icaza <miguel@ximian.com>
1543 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
1544 not catch the Error_ObjectRefRequired in SimpleName (as it is
1545 possible to have a class/instance variable name that later gets
1546 deambiguated), we have to check this here.
1548 2002-07-10 Ravi Pratap <ravi@ximian.com>
1550 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
1551 make static and put into Expression.
1553 (Event.Define): Register the private field of the event with the
1554 TypeManager so that GetFieldFromEvent can get at it.
1556 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
1557 keep track of the private field associated with an event which
1560 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
1563 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
1565 2002-07-10 Miguel de Icaza <miguel@ximian.com>
1567 * expression.cs (Binary.EmitBranchable): this routine emits the
1568 Binary expression in a branchable context. This basically means:
1569 we need to branch somewhere, not just get the value on the stack.
1571 This works together with Statement.EmitBoolExpression.
1573 * statement.cs (Statement.EmitBoolExpression): Use
1576 2002-07-09 Miguel de Icaza <miguel@ximian.com>
1578 * statement.cs (For): Reduce the number of jumps in loops.
1580 (For): Implement loop inversion for the For statement.
1582 (Break): We can be breaking out of a Try/Catch controlled section
1583 (foreach might have an implicit try/catch clause), so we need to
1584 use Leave instead of Br.
1586 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
1587 now). If the instace expression supports IMemoryLocation, we use
1588 the AddressOf method from the IMemoryLocation to extract the
1589 address instead of emitting the instance.
1591 This showed up with `This', as we were emitting the instance
1592 always (Emit) instead of the Address of This. Particularly
1593 interesting when This is a value type, as we dont want the Emit
1594 effect (which was to load the object).
1596 2002-07-08 Miguel de Icaza <miguel@ximian.com>
1598 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
1600 * statement.cs (Checked): Set the CheckedState during the resolve
1601 process too, as the ConvCast operations track the checked state on
1602 the resolve process, and not emit.
1604 * cs-parser.jay (namespace_member_declaration): Flag that we have
1605 found a declaration when we do. This is used to flag error 1529
1607 * driver.cs: Report ok when we display the help only.
1609 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
1611 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
1613 2002-07-04 Miguel de Icaza <miguel@ximian.com>
1615 * cs-tokenizer.cs (define): We also have to track locally the
1616 defines. AllDefines is just used for the Conditional Attribute,
1617 but we also need the local defines for the current source code.
1619 2002-07-03 Miguel de Icaza <miguel@ximian.com>
1621 * statement.cs (While, For, Do): These loops can exit through a
1622 Break statement, use this information to tell whether the
1623 statement is the last piece of code.
1625 (Break): Flag that we break.
1627 * codegen.cs (EmitContexts): New `Breaks' state variable.
1629 2002-07-03 Martin Baulig <martin@gnome.org>
1631 * class.cs (TypeContainer.MethodModifiersValid): Allow override
1632 modifiers in method declarations in structs. Otherwise, you won't
1633 be able to override things like Object.Equals().
1635 2002-07-02 Miguel de Icaza <miguel@ximian.com>
1637 * class.cs (Method, Property, Indexer): Do not allow the public
1638 modifier to be used in explicit interface implementations.
1640 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
1641 override modifiers in method declarations in structs
1643 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
1645 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
1646 integer or real overflow, report an error
1648 2002-07-02 Martin Baulig <martin@gnome.org>
1650 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
1651 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
1652 to tell the runtime about our newly created System.Object and
1653 System.ValueType types.
1655 2002-07-02 Miguel de Icaza <miguel@ximian.com>
1657 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
1658 struct instead of Ldarg/Starg.
1660 2002-07-02 Martin Baulig <martin@gnome.org>
1662 * expression.cs (Indirection.Indirection): Call
1663 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
1665 2002-07-02 Martin Baulig <martin@gnome.org>
1667 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
1668 ValueType, call TypeManager.TypeToCoreType() on it.
1669 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
1670 the OpCodes.Newarr argument.
1672 2002-07-02 Martin Baulig <martin@gnome.org>
1674 * expression.cs (Invocation.EmitCall): When compiling corlib,
1675 replace all calls to the system's System.Array type to calls to
1676 the newly created one.
1678 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
1679 System.Array methods.
1680 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
1681 from the system's System.Array type which must be replaced.
1683 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
1685 * typemanager.cs: load unverifiable_code_ctor so we can build
1686 corlib using the correct type. Avoid using GetTypeCode() with
1688 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
1689 TypeManager.object_type to allow building corlib.
1691 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
1693 * ecore.cs: handle System.Enum separately in LoadFromPtr().
1695 2002-07-01 Martin Baulig <martin@gnome.org>
1697 * class.cs: Make the last change actually work, we need to check
1698 whether `ifaces != null' to avoid a crash.
1700 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
1702 * class.cs: when we build structs without fields that implement
1703 interfaces, we need to add the interfaces separately, since there is
1704 no API to both set the size and add the interfaces at type creation
1707 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
1709 * expression.cs: the dimension arguments to the array constructors
1710 need to be converted if they are a long.
1712 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
1714 * class.cs: don't emit ldarg.0 if there is no parent constructor
1715 (fixes showstopper for corlib).
1717 2002-06-29 Martin Baulig <martin@gnome.org>
1719 MCS now compiles corlib on GNU/Linux :-)
1721 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
1722 ie. check for MethodImplOptions.InternalCall.
1724 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
1725 and TypeManager.attribute_type are null, so we must explicitly check
1726 whether parent is not null to find out whether it's an attribute type.
1727 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
1728 and SetBuilder, not only if the property is neither abstract nor external.
1729 This is necessary to set the MethodImplOptions on the accessor methods.
1730 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
1731 SetBuilder, see Property.Emit().
1733 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
1734 populate "System.Object", "System.ValueType" and "System.Attribute" since
1735 they've already been populated from BootCorlib_PopulateCoreTypes().
1737 2002-06-29 Martin Baulig <martin@gnome.org>
1739 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
1740 is the NullLiteral, we also need to make sure that target_type is not
1743 2002-06-29 Martin Baulig <martin@gnome.org>
1745 * rootcontext.cs (RootContext.ResolveCore): We must initialize
1746 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
1747 before calling BootstrapCorlib_ResolveDelegate ().
1749 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1751 * statement.cs: fixed build-breaker. All tests passed ok.
1753 2002-06-27 Martin Baulig <martin@gnome.org>
1755 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
1756 for System.Decimal when compiling corlib.
1758 2002-06-27 Martin Baulig <martin@gnome.org>
1760 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
1761 switch blocks which contain nothing but a default clause.
1763 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
1765 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
1767 2002-06-27 Martin Baulig <martin@gnome.org>
1769 * ecore.cs (PropertyExpr.PropertyExpr): Call
1770 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
1772 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
1773 is already a TypeBuilder.
1775 2002-06-27 Martin Baulig <martin@gnome.org>
1777 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
1778 `target_type == TypeManager.array_type', not IsAssignableFrom() in
1779 the "from an array-type to System.Array" case. This makes it work
1780 when compiling corlib.
1782 2002-06-27 Martin Baulig <martin@gnome.org>
1784 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
1785 non-static PropertyExpr, set its InstanceExpression. This makes
1786 the `ICollection.Count' property work in System/Array.cs.
1788 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
1790 * driver.cs: Made error handling more consistent. Errors now
1791 tracked by Report class, so many methods which used to return int
1792 now return void. Main() now prints success/failure and
1793 errors/warnings message.
1795 Renamed '--probe' compiler argument to '--expect-error'. Removed
1796 the magic number return values (123 and 124). Now, if the
1797 expected error occurs, the compiler exits with success (exit value
1798 0). If the compilation completes without seeing that particular
1799 error, the compiler exits with failure (exit value 1). The
1800 makefile in mcs/errors has been changed to handle the new behaviour.
1802 * report.cs: Made 'expected error' number a property and renamed
1803 it from 'Probe' to 'ExpectedError'.
1805 * genericparser.cs: Removed error handling support, since it is
1806 now all done by Report class.
1808 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
1809 class, so parse() no longer returns an int.
1811 * namespace.cs: Use Report.Error instead of GenericParser.error
1813 2002-06-22 Miguel de Icaza <miguel@ximian.com>
1815 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
1816 TypeContainer.AddOperator): At the front of the list put the
1817 explicit implementations, so they get resolved/defined first.
1819 2002-06-21 Miguel de Icaza <miguel@ximian.com>
1821 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
1822 interface type is implemented by this TypeContainer. Used during
1823 explicit interface implementation.
1825 (Property.Define, Indexer.Define, Method.Define): Validate that
1826 the given interface in the explicit implementation is one of the
1827 base classes for the containing type.
1829 Also if we are explicitly implementing an interface, but there is
1830 no match in the pending implementation table, report an error.
1832 (Property.Define): Only define the property if we are
1833 not explicitly implementing a property from an interface. Use the
1834 correct name also for those properties (the same CSC uses,
1835 although that is really not needed).
1837 (Property.Emit): Do not emit attributes for explicitly implemented
1838 properties, as there is no TypeBuilder.
1840 (Indexer.Emit): ditto.
1842 Hiding then means that we do not really *implement* a pending
1843 implementation, which makes code fail.
1845 2002-06-22 Martin Baulig <martin@gnome.org>
1847 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
1848 the return value of Object.GetType(). [FIXME: we need to do this whenever
1849 we get a type back from the reflection library].
1851 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
1853 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
1855 2002-06-20 Miguel de Icaza <miguel@ximian.com>
1857 * attribute.cs: Return null if we can not look up the type.
1859 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
1860 the interface types found.
1862 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
1863 interface types found.
1865 * typemanager.cs (GetInterfaces): Make this routine returns alll
1866 the interfaces and work around the lame differences between
1867 System.Type and System.Reflection.Emit.TypeBuilder in the results
1868 result for GetInterfaces.
1870 (ExpandInterfaces): Given an array of interface types, expand and
1871 eliminate repeated ocurrences of an interface. This expands in
1872 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
1875 2002-06-21 Martin Baulig <martin@gnome.org>
1877 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
1880 2002-06-21 Martin Baulig <martin@gnome.org>
1882 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
1883 and called with one of the core types, return the corresponding typebuilder for
1886 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
1889 2002-06-21 Martin Baulig <martin@gnome.org>
1891 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
1892 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
1893 (Expression.ConvertReferenceExplicit): Likewise.
1895 * expression.cs (ElementAccess.DoResolve): Likewise.
1896 (ElementAccess.DoResolveLValue): Likewise.
1898 2002-06-10 Martin Baulig <martin@gnome.org>
1900 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
1901 add the "value" parameter to the parameter list.
1903 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
1906 2002-06-19 Miguel de Icaza <miguel@ximian.com>
1908 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
1909 the argument to an int, uint, long or ulong, per the spec. Also
1910 catch negative constants in array creation.
1912 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
1914 * class.cs: do not allow the same interface to appear twice in
1915 the definition list.
1917 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
1919 * ecore.cs: don't use ldlen with System.Array.
1921 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
1923 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
1925 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
1927 * modifiers.cs: produce correct field attributes for protected
1928 internal. Easy fix so miguel can work on ther harder stuff:-)
1930 2002-06-18 Miguel de Icaza <miguel@ximian.com>
1932 * pending.cs: New file. Move the code from class.cs here.
1933 Support clearning the pending flag for all methods (when not doing
1934 explicit interface implementation).
1936 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
1938 * rootcontext.cs: added a couple more types needed to bootstrap.
1940 2002-06-17 Miguel de Icaza <miguel@ximian.com>
1942 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
1943 constructor in the type, instead of any constructor in the type
1944 hierarchy. Thanks to Paolo for finding this bug (it showed up as
1945 a bug in the Mono runtime when applying the params attribute).
1947 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1948 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
1950 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
1952 * expression.cs (Unary.ResolveOperator): Use TypeManager
1953 to resolve the type.
1955 2002-06-13 Ravi Pratap <ravi@ximian.com>
1957 * cs-parser.jay (enum_member_declaration): Pass in the attributes
1960 * enum.cs (AddEnumMember): Add support to store the attributes associated
1961 with each member too.
1963 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
1964 field builders too - this takes care of the enum member case.
1966 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
1968 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
1969 address-of operator on both value types and pointers.
1971 2002-06-10 Martin Baulig <martin@gnome.org>
1973 * interface.cs (Interface.PopulateIndexer): Add the indexer's
1974 PropertyBuilder to the `property_builders' list.
1976 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
1977 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
1978 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
1979 find any indexers which are inherited from an interface.
1981 2002-06-09 Martin Baulig <martin@gnome.org>
1983 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
1984 the same type as the constant if necessary. There's also a test-130.cs
1987 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
1989 * typemanager.cs (TypeManager.ChangeType): Previously known as
1990 Enum.ChangeEnumType().
1992 2002-06-09 Martin Baulig <martin@gnome.org>
1994 * expression.cs (Cast.TryReduce): Added support for consts.
1996 2002-06-08 Ravi Pratap <ravi@ximian.com>
1998 * class.cs (Accessor): Hold attributes information so we can pass
2001 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
2002 Modify to pass in attributes attached to the methods.
2004 (add_accessor_declaration, remove_accessor_declaration): Ditto.
2006 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
2007 to handle the Accessor kind :-)
2009 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
2011 2002-06-08 Martin Baulig <martin@gnome.org>
2013 * expression.cs (Unary.TryReduceNegative): Added support for
2016 2002-06-08 Martin Baulig <martin@gnome.org>
2018 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
2019 name can't be found in the `defined_names' - the caller will do a
2020 MemberLookup in this case and thus find methods in System.Enum
2021 such as Enum.IsDefined().
2023 2002-06-08 Martin Baulig <martin@gnome.org>
2025 * enum.cs (Enum.ChangeEnumType): This is a custom version of
2026 Convert.ChangeType() which works with TypeBuilder created types.
2027 (Enum.LookupEnumValue, Enum.Define): Use it here.
2029 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
2030 `TypeBuilder.BaseType != null' check.
2031 (TypeContainer.FindMembers): Only lookup parent members if we
2032 actually have a parent.
2033 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
2034 (ConstructorInitializer.Resolve): Likewise.
2036 * interface.cs (Interface.FindMembers): Added
2037 `TypeBuilder.BaseType != null' check.
2039 * rootcontext.cs (RootContext.ResolveCore): Added
2040 "System.Runtime.CompilerServices.IndexerNameAttribute" to
2041 classes_second_stage.
2043 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
2044 debug_type and trace_type when compiling with --nostdlib.
2046 2002-06-07 Martin Baulig <martin@gnome.org>
2048 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
2049 (AddField): Set it to true when adding a non-static field.
2050 (DefineType): Use `have_nonstatic_fields' to find out whether we
2051 have non-static fields, not `Fields != null'.
2053 2002-06-02 Miguel de Icaza <miguel@ximian.com>
2055 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
2056 dereferencing a null on the static-field code path)
2058 2002-05-30 Martin Baulig <martin@gnome.org>
2060 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
2061 to take command line arguments. Use reflection to call the new
2062 custom `Initialize' function on the symbol writer and pass it the
2063 command line arguments.
2065 * driver.cs (--debug-args): New command line argument to pass command
2066 line arguments to the symbol writer.
2068 2002-05-28 Miguel de Icaza <miguel@ximian.com>
2070 * assign.cs (DoResolve): Forgot to do the implicit conversion to
2071 the target type for indexers and properties. Thanks to Joe for
2074 2002-05-27 Miguel de Icaza <miguel@ximian.com>
2076 * typemanager.cs (MethodFlags): returns the method flags
2077 (Obsolete/ShouldIgnore) that control warning emission and whether
2078 the invocation should be made, or ignored.
2080 * expression.cs (Invocation.Emit): Remove previous hack, we should
2081 not do this on matching a base type, we should do this based on an attribute
2083 Only emit calls to System.Diagnostics.Debug and
2084 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
2085 on the command line.
2087 * rootcontext.cs: Global settings for tracing and debugging.
2089 * cs-tokenizer.cs (define): New utility function to track
2090 defines. Set the global settings for TRACE and DEBUG if found.
2092 2002-05-25 Ravi Pratap <ravi@ximian.com>
2094 * interface.cs (Populate*): Pass in the TypeContainer as well as
2095 the DeclSpace as parameters so that we can create EmitContexts and
2096 then use that to apply attributes etc.
2098 (PopulateMethod, PopulateEvent, PopulateProperty)
2099 (PopulateIndexer): Apply attributes everywhere.
2101 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
2104 (ApplyAttributes): Update accordingly.
2106 We now apply interface attributes for all members too.
2108 2002-05-26 Miguel de Icaza <miguel@ximian.com>
2110 * class.cs (Indexer.Define); Correctly check if we are explicit
2111 implementation (instead of checking the Name for a ".", we
2112 directly look up if the InterfaceType was specified).
2114 Delay the creation of the PropertyBuilder.
2116 Only create the PropertyBuilder if we are not an explicit
2117 interface implementation. This means that explicit interface
2118 implementation members do not participate in regular function
2119 lookups, and hence fixes another major ambiguity problem in
2120 overload resolution (that was the visible effect).
2122 (DefineMethod): Return whether we are doing an interface
2125 * typemanager.cs: Temporary hack until we get attributes in
2126 interfaces (Ravi is working on that) and we get IndexerName
2127 support in interfaces.
2129 * interface.cs: Register the indexers as properties.
2131 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
2132 warning, I have verified that this is a bug in the .NET runtime
2133 (JavaScript suffers of the same problem).
2135 * typemanager.cs (MemberLookup): When looking up members for
2136 interfaces, the parent of an interface is the implicit
2137 System.Object (so we succeed in searches of Object methods in an
2138 interface method invocation. Example: IEnumerable x; x.ToString
2141 2002-05-25 Miguel de Icaza <miguel@ximian.com>
2143 * class.cs (Event): Events should also register if they do
2144 implement the methods that an interface requires.
2146 * typemanager.cs (MemberLookup); use the new GetInterfaces
2149 (GetInterfaces): The code used to lookup interfaces for a type is
2150 used in more than one place, factor it here.
2152 * driver.cs: Track the errors at the bottom of the file, we kept
2155 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
2156 instance if the method we are calling is static!
2158 2002-05-24 Miguel de Icaza <miguel@ximian.com>
2160 * attribute.cs (ApplyAttributes): Make this function filter out
2161 the IndexerName attribute (as that attribute in reality is never
2162 applied) and return the string constant for the IndexerName
2165 * class.cs (TypeContainer.Emit): Validate that all the indexers
2166 have the same IndexerName attribute, and if so, set the
2167 DefaultName attribute on the class.
2169 * typemanager.cs: The return value might contain other stuff (not
2170 only methods). For instance, consider a method with an "Item"
2171 property and an Item method.
2173 * class.cs: If there is a problem with the parameter types,
2176 2002-05-24 Ravi Pratap <ravi@ximian.com>
2178 * ecore.cs (ImplicitConversionExists): Wrapper function which also
2179 looks at user defined conversion after making a call to
2180 StandardConversionExists - we need this for overload resolution.
2182 * expression.cs : Update accordingly the various method calls.
2184 This fixes 2 bugs filed against implicit user defined conversions
2186 2002-05-22 Miguel de Icaza <miguel@ximian.com>
2188 * statement.cs: Track the result of the assignment.
2190 2002-05-21 Miguel de Icaza <miguel@ximian.com>
2192 * expression.cs (MemberAccess): Improved error reporting for
2193 inaccessible members.
2195 2002-05-22 Martin Baulig <martin@gnome.org>
2197 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
2198 itself with debugging support.
2200 2002-05-22 Martin Baulig <martin@gnome.org>
2202 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
2203 Removed, this isn't needed anymore.
2205 2002-05-20 Martin Baulig <martin@gnome.org>
2207 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
2208 be underlying type for an enum.
2210 2002-05-20 Miguel de Icaza <miguel@ximian.com>
2212 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
2213 that splits out the loading of just the core types.
2215 * rootcontext.cs (ResolveCore): Split the struct resolution in
2216 two, so we can load the enumeration underlying types before any
2219 * expression.cs (Is): Bandaid until we fix properly Switch (see
2220 bug #24985 for details).
2222 * typemanager.cs (ImplementsInterface): The hashtable will contain
2223 a null if there are no interfaces implemented.
2225 2002-05-18 Miguel de Icaza <miguel@ximian.com>
2227 * cs-parser.jay (indexer_declarator): It is fine to have array
2230 2002-05-17 Miguel de Icaza <miguel@ximian.com>
2232 * typemanager.cs: (RegisterBuilder): New function used to register
2233 TypeBuilders that implement interfaces. Since
2234 TypeBuilder.GetInterfaces (as usual) does not work with lame
2236 (AddUserType): register interfaces.
2238 (ImplementsInterface): Use the builder_to_ifaces hash if we are
2239 dealing with TypeBuilder. Also, arrays are showing up as
2240 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
2241 methods can not be invoked on them!
2243 * ecore.cs (ExplicitReferenceConversionExists): Made public.
2244 (ImplicitReferenceConversionExists): Split out from
2245 StandardConversionExists.
2247 * expression.cs (As): We were only implementing one of the three
2248 cases for the as operator. We now implement them all.
2249 (Is): Implement the various other cases for Is as well.
2251 * typemanager.cs (CACHE): New define used to control if we want or
2252 not the FindMembers cache. Seems to have a negative impact on
2253 performance currently
2255 (MemberLookup): Nested types have full acess to
2256 enclosing type members
2258 Remove code that coped with instance/static returns for events, we
2259 now catch this in RealFindMembers.
2261 (RealFindMembers): only perform static lookup if the instance
2262 lookup did not return a type or an event.
2264 2002-05-17 Miguel de Icaza <miguel@ximian.com>
2266 * assign.cs (CompoundAssign): We pass more semantic information
2267 now to Compound Assignments than we did before: now we have all
2268 the information at hand, and now we resolve the target *before* we
2269 do the expression expansion, which allows the "CacheValue" method
2270 to have the effect we intended (before, a [x] += 1 would generate
2271 two differen ArrayAccess expressions from the ElementAccess,
2272 during the resolution process).
2274 (CompoundAssign.DoResolve): Resolve target and original_source here.
2276 2002-05-16 Miguel de Icaza <miguel@ximian.com>
2278 * expression.cs (ArrayAccess): dropped debugging information.
2280 * typemanager.cs: Small bug fix: I was always returning i_members,
2281 instead of one of i_members or s_members (depending on which had
2284 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
2285 method is invoked before any code generation takes place, and it
2286 is a mechanism to inform that the expression will be invoked more
2287 than once, and that the method should use temporary values to
2288 avoid having side effects
2290 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
2292 * ecore.cs (Expression.CacheTemporaries): Provide empty default
2295 * expression.cs (Indirection, ArrayAccess): Add support for
2296 CacheTemporaries in these two bad boys.
2298 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
2300 (StoreFromPtr): Handle stobj as well.
2302 * expression.cs (UnaryMutator): Share more code.
2304 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
2305 down: I was not tracking the Filter function as well, which
2306 was affecting the results of the cache.
2308 2002-05-15 Miguel de Icaza <miguel@ximian.com>
2310 * attribute.cs: Remove the hack to handle the CharSet property on
2313 2002-05-14 Miguel de Icaza <miguel@ximian.com>
2315 * attribute.cs (DoResolve): More uglyness, we now only try to
2316 resolve the attribute partially, to extract the CharSet
2317 information (only if we are a StructLayout attribute). Otherwise
2319 (GetExtraTypeInfo): Add some code to conditionally kill in the
2320 future this. I am more and more convinced that the .NET
2321 framework has special code to handle the attribute setting on
2324 * expression.cs (IsParamsMethodApplicable): Revert my previous
2325 foreach change here, it was wrong.
2327 2002-05-13 Miguel de Icaza <miguel@ximian.com>
2329 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
2330 (pp_expr): do not abort on unknown input, just return.
2331 (eval): abort if there are pending chars.
2333 * attribute.cs (Attribute.Resolve): Positional parameters are
2334 optional. Deal with that case.
2336 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
2337 the Ansi/Unicode/Auto information for the type.
2339 (TypeContainer.DefineType): instantiate the EmitContext here, as
2340 we will be using it during the type definition (to resolve
2341 attributes) and during the emit phase.
2343 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
2344 to pull type information out of the attributes
2346 (Attribute.Resolve): track the constructor builder, and allow for
2347 multiple invocations (structs and classes will use this).
2349 * ecore.cs (MemberLookupFinal): new version with all the
2350 parameters customizable.
2352 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
2353 constructors. Return if the result value is null (as the error
2354 would have been flagged already by MemberLookupFinal)
2356 Do not allow instances of abstract classes or interfaces to be
2359 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
2360 We have to compare the assembly property here when dealing with
2361 FamANDAssem and Assembly access modifiers, because we might be
2362 creating an assembly from *modules* (that means that we are not
2363 getting TypeBuilders for types defined in other modules that are
2364 part of this assembly).
2366 (Method.Emit): If the method is marked abstract and has a body,
2369 (TypeContainer.DefineMembers): If both the defined member and the
2370 parent name match are methods, then do not emit any warnings: let
2371 the Method.Define routine take care of flagging warnings. But if
2372 there is a mismatch (method overrides something else, or method is
2373 overriwritten by something, then emit warning).
2375 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
2376 set to null, this means `do not check for the return type on the
2379 (Method.Define): set the return type for the method signature to
2380 null, so that we get methods with the same name and parameters and
2381 different return types. This is used to flag warning 114 (you are
2382 hiding a method, and you probably want to use the new/override
2385 * typemanager.cs (MemberLookup): Implemented proper access
2386 control, closing a long standing set of bug reports. The problem
2387 was that the Framework only has two bits: Public and NonPublic,
2388 and NonPublic includes private and protected methods, but we need
2389 to enforce the FamANDAssem, FamOrAssem and Family.
2391 2002-05-11 Miguel de Icaza <miguel@ximian.com>
2393 * statement.cs (GotoCase): Return true: Ammounts to giving up
2394 knowledge on whether we return or not, and letting the other case
2395 be responsible for it.
2397 2002-05-10 Miguel de Icaza <miguel@ximian.com>
2399 * driver.cs: Do not load directories for each file processed, only
2400 do it if there is a pattern.
2402 * ecore.cs: Report readonly assigns here as well, as we might have
2403 been resolved only by MemberAccess.
2405 (SimpleName.SimpleNameResolve): Also be useful for LValue
2406 resolution. We need this to propagate assign to local readonly variables
2408 * typemanager.cs: Use a ptrhashtable for the criteria, because we
2409 do not want to reuse potential criteria memory.
2411 * class.cs (MyEventBuilder): Set reflected_type;
2413 * ecore.cs (Constantify): Added support for constifying bools.
2415 (RootContext.LookupType): Added a cache for values looked up in
2416 the declaration space.
2418 * typemanager.cs (FindMembers): Now is a front-end to
2419 RealFindMembers, and provides a two-level hashtable-based cache to
2422 15% performance improvement: from 22.5 to 19.2 seconds.
2424 * expression.cs (IsParamsMethodApplicable): use foreach.
2425 (Invocation.DoResolve): ditto.
2426 (New.DoResolve): ditto.
2427 (ArrayCreation.DoResolve): ditto.
2429 * ecore.cs (FindMostEncompassingType): use foreach.
2431 * delegate.cs (NewDelegate.DoResolve): Use foreach
2433 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
2434 (RemoveMethods): use foreach.
2436 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
2437 nested foreach statements instead of for, and also break out of
2438 the inner loop once a match is found.
2440 (Invocation.OverloadResolve): Use foreach, simplify the code.
2442 2002-05-08 Miguel de Icaza <miguel@ximian.com>
2444 * cfold.cs (BinaryFold): During an enumeration evaluation context,
2445 we actually unwrap the expression to allow for extra information
2448 * expression.cs: Use Shr_Un on unsigned operations.
2450 2002-05-08 Ravi Pratap <ravi@ximian.com>
2452 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
2453 applicable operators was not being considered correctly. This closes
2454 the bug Miguel reported.
2456 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
2458 * attribute.cs: check that the type derives from System.Attribute
2459 and report the correct error in that case (moved the duplicate code to
2460 its own method, too).
2462 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
2464 * attribute.cs: lookup attribute type name as the spec says: first the
2465 bare attribute name and then name + "Attribute" (nant compiles with
2466 mcs after this fix).
2468 2002-05-07 Miguel de Icaza <miguel@ximian.com>
2470 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
2471 Because of the way we parse things, we should try to see if a
2472 UIntConstant can fit in an integer.
2474 2002-05-07 Ravi Pratap <ravi@ximian.com>
2476 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
2477 when we are in an explicit context.
2479 (ConvertReferenceExplicit): When converting from Iface type S to Class
2480 T make sure the rules are implemented as an OR.
2482 * parameter.cs (ParameterType): Make it a property for now although the
2483 purpose really isn't anything immediate.
2485 * expression.cs (Is*Applicable): Do better checking on the parameter type
2486 of a ref/out parameter. The ones from the system assemblies are already
2487 marked with the correct type so we don't need to do any correction.
2489 * ecore.cs (StandardConversionExists): Conversion from Interface types to
2490 the object type is standard too so include that.
2492 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2494 * ecore.cs (StandardConversionExists): Augment with missing code:
2495 deal with IntConstant, LongConstants and Enumerations.
2497 * assign.cs: Report the error, instead of failing silently
2499 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
2500 typecontainer that they are declared, because the
2501 typecontainer/namespace will have the list of using clauses that
2504 Assembly Attributes were escaping the normal registration
2507 (EmitCode): Apply attributes within an EmitContext that represents
2508 the container they were declared on.
2510 * cs-parser.jay: Track bases for structs. How did I get this wrong?
2512 2002-05-06 Ravi Pratap <ravi@ximian.com>
2514 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
2515 Revamp completely - make much cleaner as we now operate only
2518 (FindMostSpecificSource, FindMostSpecificTarget): New methods
2519 to implement the logic detailed in the spec more correctly.
2521 (UserDefinedConversion): Update accordingly.
2523 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2525 * statement.cs: Return flow analysis information up.
2527 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
2530 (token): Do not consume an extra character before calling
2533 2002-05-06 Piers Haken <piersh@friskit.com>
2535 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
2537 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2539 * class.cs (Constructor.Emit): Set the IsStatic flag in the
2540 EmitContext during the instance constructor initializer
2541 resolution, to stop access to instance variables.
2543 This is mandated by the spec, last paragraph of the `constructor
2544 initializers' section.
2546 2002-05-05 Miguel de Icaza <miguel@ximian.com>
2548 * cs-parser.jay, class.cs (Accessor): new class used to represent
2549 an accessor (get or set). In the past we used `null' to represent
2550 a missing accessor. But this is ambiguous because there was no
2551 way to tell in abstract indexers/properties if one of them was
2554 Now there is a way of addressing that.
2556 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
2557 instead of FindMembers.
2559 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
2560 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
2562 * attribute.cs: Treat indexers and properties as the same in terms
2563 of applying attributes
2565 * ecore.cs (FindMostEncompassedType): Use statically initialized
2566 EmptyExpressions()s like we do elsewhere to avoid creating useless
2567 objects (and we take this out of the tight loop).
2569 (GetConversionOperators): Move the code to extract the actual
2570 operators to a separate routine to clean things up.
2572 2002-05-04 Miguel de Icaza <miguel@ximian.com>
2574 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
2575 events are always registered FieldBuilders.
2577 * class.cs (FieldBase): New class shared by Fields
2579 * delegate.cs: If we are a toplevel delegate, use our full name.
2580 If we are a nested delegate, then only use our tail name.
2582 2002-05-02 Ravi Pratap <ravi@ximian.com>
2584 * expression.cs (IsApplicable): Ensure that we add the "&" to
2585 ref/out types before comparing it with the type of the argument.
2587 (IsParamsMethodApplicable): Ditto.
2589 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
2592 * delegate.cs : Handle the case when we have more than one applicable
2593 method. Flag an error only when we finish checking all.
2595 2002-05-02 Miguel de Icaza <miguel@ximian.com>
2597 * expression.cs: Add support for boolean static initializers.
2599 2002-05-01 Miguel de Icaza <miguel@ximian.com>
2601 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
2603 * parameter.cs (ComputeParameterTypes,
2604 ComputeAndDefineParameterTypes): Better error handling: now we
2605 clear the `types' cache if we fail during any of the type lookups.
2606 We also return the status code correctly to our caller
2608 * delegate.cs: If we fail to define a delegate, abort the extra
2611 * expression.cs (Binary.ResolveOperator): for
2612 operator==(object,object) and operator !=(object, object) we also
2613 have to verify that there is an implicit conversion from one to
2616 (ArrayAccess.DoResolve): Array Access can operate on
2619 2002-04-30 Miguel de Icaza <miguel@ximian.com>
2621 * assign.cs (CompoundAssign): A new class used as a "flag" that
2622 the assignment actually is happening as part of a compound
2623 assignment operator.
2625 During compound assignment, a few new rules exist to enable things
2632 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
2633 to the type of x) if y is implicitly convertible to the type of x,
2634 and the operator is a builtin operator and the return type of the
2635 operator is explicitly convertible to the type of x.
2637 * rootcontext.cs: Reset warning level to 2. 4 catches various
2638 "interesting" features in mcs, we must clean this up at some
2639 point, but currently am trying to kill other bugs ;-)
2641 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
2642 in container classes as well.
2644 * expression.cs (Binary.ResolveOperator): Handle string case
2645 before anything else (as operator overloading does emit an error
2646 before doing anything else).
2648 This code could go away when we move to a table driven model, but
2649 i could not come up with a good plan last night.
2651 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
2653 * typemanager.cs (CSharpName): reimplementation using regex.
2654 * class.cs: added null check for fields in Emit
2655 * rootcontext.cs: set warninglevel to 4
2657 2002-04-29 Miguel de Icaza <miguel@ximian.com>
2659 * typemanager.cs (CSharpName): reimplemented with Lupus
2662 2002-04-28 Miguel de Icaza <miguel@ximian.com>
2664 * statement.cs (If): correclty implement Resolve, because we were
2665 not catching sem errors in there. The same process is needed
2667 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
2670 (Statement.Warning_DeadCodeFound): Factorize code.
2671 (While): Report dead code here too.
2673 (Statement): Added Resolve virtual method to allow
2674 for resolution split from the emit code.
2676 2002-04-26 Miguel de Icaza <miguel@ximian.com>
2678 * statement.cs (EmitBoolExpression): No longer try to resolve the
2680 (MakeBoolean): New utility function that resolve, implicitly
2681 converts to boolean and tags the expression.
2684 (If, Do): Implement dead code elimination.
2685 (While): Implement loop inversion
2687 (Do, While, For, If): Resolve the expression prior to calling our
2690 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
2693 - added method Report28 (warning: program has more than one entry point)
2694 - added method IsEntryPoint, implements paragraph 10.1 of the spec
2695 - modified method Method.Define, the part at the end of the method
2697 * rootcontext.cs: added static public Location EntryPointLocation;
2699 * ../errors/cs0028.cs : Add test case for the above warning.
2702 - modified method CSharpName to allow arrays of primitive type to
2703 be printed nicely (e.g. instead of System.Int32[][] it now prints
2705 - added method CSharpSignature: returns the signature of a method
2706 in string format to be used in reporting errors, warnings, etc.
2708 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
2711 2002-04-26 Ravi Pratap <ravi@ximian.com>
2713 * delegate.cs (Define): Fix extremely silly bug where I was
2714 setting the type of the 'object' parameter of the BeginInvoke
2715 method to System.IAsyncResult instead of System.Object ;-)
2717 2002-04-26 Miguel de Icaza <miguel@ximian.com>
2719 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
2722 (Constructor.Emit): return if we fail to initialize the
2723 constructor. Another door closed!
2725 * expression.cs (New.DoResolve): Improve error message (from -6 to
2726 1501). Use DeclaredOnly lookup to find the exact constructor.
2728 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
2729 loop. This is useful.
2731 * cs-parser.jay: Adjust the default parameters so that destructors
2732 have the proper signature.
2734 2002-04-26 Martin Baulig <martin@gnome.org>
2736 * driver.cs (LoadAssembly): If `assembly' contains any characters
2737 which are only valid in path names and not in assembly names
2738 (currently slash, backslash and point), use Assembly.LoadFrom ()
2739 instead of Assembly.Load () on the `assembly' (before iteration
2740 over the link_paths).
2742 2002-04-26 Martin Baulig <martin@gnome.org>
2744 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
2746 2002-04-25 Miguel de Icaza <miguel@ximian.com>
2748 * class.cs (Property): use the new typemanager.MemberLookup
2750 (TypeContainer.MemberLookup): Implement using the
2751 TypeManager.MemberLookup now.
2753 * typemanager.cs: Make MemberLookup a function of the TypeManager,
2754 and return MemberInfos, so that these can be used without an
2755 EmitContext (what we had before).
2757 2002-04-24 Miguel de Icaza <miguel@ximian.com>
2759 * expression.cs: Fix the case where the argument to params if the
2760 type of the params. I omitted handling this before. Fixed
2762 2002-04-22 Miguel de Icaza <miguel@ximian.com>
2764 * driver.cs: Call BootCorlib_PopulateCoreType
2766 * class.cs (Property.CheckBase): Check for properties only, not
2769 * interface.cs: Temporary hack: try/catch around the
2770 CustomAttributeBuilder, because I am getting an exception that I
2773 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
2774 types whose definitions are required to be there (attributes are
2775 defined before standard types).
2777 Compute definitions as we boot the various types, as they are used
2778 immediately (value_type class will need object_type, but if we do
2779 not initialize object_type, we will pass a null, which will let
2780 the runtime pick the System.Object from the existing corlib, which
2781 is not what we want).
2783 2002-04-22 Patrik Torstensson <totte@labs2.com>
2785 * cs-tokenizer.cs: fixed a number of trim() issues.
2787 2002-04-22 Ravi Pratap <ravi@ximian.com>
2789 * expression.cs (Argument.Type): Ensure that we return the correct
2790 type when we have out or ref parameters [in which case we
2793 2002-04-22 Miguel de Icaza <miguel@ximian.com>
2795 * class.cs (Property, Indexer): Allow extern modifier in there.
2797 * typemanager.cs (InitBaseTypes): Initializes object_type and
2798 value_type, since those will be used early on during the bootstrap
2799 process to compile corlib.
2801 (InitCoreTypes): Move code from here to InitBaseTypes.
2803 2002-04-21 Miguel de Icaza <miguel@ximian.com>
2805 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
2806 single-dimension arrays as using the ldlen opcode.
2808 Daniel Lewis discovered this optimization.
2810 * typemanager.cs: Add signature for System.Array::get_Length
2812 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2814 * statement.cs: report the error when the foreach does not apply to an
2815 array nor a collection.
2817 2002-04-19 Miguel de Icaza <miguel@ximian.com>
2819 * expression.cs: Add implicit conversions to the operator ~.
2821 * constant.cs (DecimalConstant.Emit): Emit decimal value.
2823 * typemanager.cs: Locate the decimal constructor.
2825 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2827 * attribute.cs: use the new property of TypeOf.
2828 * expression.cs: added 'get' property around typearg.
2830 These changes fix a build breaker reported by NickD. Is this the
2831 correct way to fix? If not, please, revert my changes and make it
2834 2002-04-17 Miguel de Icaza <miguel@ximian.com>
2836 * attribute.cs: Add support for typeof in attribute invocations.
2837 I am not sure that this is right though.
2839 2002-04-14 Duncan Mak <duncan@ximian.com>
2841 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
2842 Binary.Operator.Division case.
2844 2002-04-13 Ravi Pratap <ravi@ximian.com>
2846 * class.cs (DefineType): Ensure that we do a proper check on
2847 attribute types and also register it with the TypeManager.
2849 (TypeContainer.Targets): The default for attribute types is
2850 AttributeTargets.All.
2852 * attribute.cs (ApplyAttributes): Registering the attribute type
2853 is done elsewhere, not when we discover we have a Usage attribute.
2855 2002-04-12 Ravi Pratap <ravi@ximian.com>
2857 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
2858 and get rid of is_delegate parameter.
2860 * everywhere : update.
2862 2002-04-12 Ravi Pratap <ravi@ximian.com>
2864 * cs-parser.jay (compilation_unit): Revamp completely to use
2865 some new ideas that I got from Rhys' grammar to solve the problems
2866 with assembly level attributes.
2868 (outer_declaration): New grammar production.
2870 (attribute_sections): Add.
2872 (opt_attributes): Base on attribute_sections
2874 (namespace_declaration): Allow opt_attributes to tackle the case
2875 when we have assembly level attributes - we are clever in this
2878 * attribute.cs (ApplyAttributes): Do not worry about assembly
2879 attributes in the non-global context.
2881 * rootcontext.cs (AddGlobalAttributes): Go back to using this
2882 instead of SetGlobalAttributes.
2884 * class.cs, rootcontext.cs : Ensure we define and generate
2885 attribute types before anything else.
2887 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
2888 and flag the new error -20 for the case when the attribute type
2889 does not have valid targets specified. csc does not catch this.
2891 * ../errors/errors.txt : update for error # -20
2893 2002-04-11 Ravi Pratap <ravi@ximian.com>
2895 * support.cs (InternalParameters.ParameterModifier): Do some null
2896 checking and return sane values.
2898 * class.cs (Method.Define): If we are a PInvoke method, ensure
2899 that we are static and extern. Report error # 601
2901 * ../errors/cs0601.cs : Add test case for the above error.
2903 2002-04-07 Ravi Pratap <ravi@ximian.com>
2905 * rootcontext.cs (attribute_types): We need to keep type of
2906 all attribute types separately and emit code for them first.
2908 (RegisterAttribute) : Implement.
2910 * class.cs (DefineType): Check if the current Type is a custom
2911 attribute type and register it accordingly.
2913 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
2914 adding the first attribute twice and rename to
2916 (SetGlobalAttributes): this.
2918 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
2921 * attribute.cs (ApplyAttributes): Take an additional argument telling us
2922 if we are processing global arguments. Hmm, I am unsure of this.
2924 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2926 * expression.cs: added static array of strings to avoid calling
2927 Enum.ToString () for Operator in Binary. Significant recover of
2930 2002-04-10 Miguel de Icaza <miguel@ximian.com>
2932 * class.cs (FindMembers): Allow the Builders of the various
2933 members to be null. If they are skip them. This only happens
2934 during the PInvoke declaration.
2936 2002-04-09 Miguel de Icaza <miguel@ximian.com>
2938 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
2939 failure, so we do not keep going afterwards.
2941 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
2942 wanted to pass `false' as the `is_delegate' argument. If this is
2943 the case, why not use delegate_type == null to mean `is_delegate =
2944 false' and anything else as is_delegate = true.
2946 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
2948 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
2949 code for the section, not the beginning of the tests.
2951 2002-04-08 Miguel de Icaza <miguel@ximian.com>
2953 * cfold.cs: Handle operator + (Enum x, Underlying x)
2955 * expression.cs (Binary): same. Warn about errors where we have
2956 Enum/Enum in operator + as well.
2958 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
2961 - added support for switch(bool)
2962 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
2963 - add TableSwitchEmit() to handle table-based switch statements
2965 2002-04-05 Ravi Pratap <ravi@ximian.com>
2967 * expression.cs (Invocation.OverloadResolve): Factor out code which
2968 does parameter compatibility checking with arguments so that we can
2969 re-use the code even from Delegate.VerifyApplicability
2971 (VerifyArgumentsCompat): Move above code here.
2973 * delegate.cs (VerifyApplicability): Get rid of duplicate code
2974 and instead make a call to the above method.
2976 2002-03-31 Ravi Pratap <ravi@ximian.com>
2978 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
2979 We use it to keep track of classes which are attribute types.
2981 2002-04-02 Miguel de Icaza <miguel@ximian.com>
2983 * delegate.cs (Delegate.Define): Correctly define the types in the
2984 presence of fixed and array parameters.
2986 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
2989 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
2990 include NonPublic after the first iteration.
2992 * class.cs (Indexer.CheckBase): Only check if both parents are
2995 * cs-parser.jay (accessor_body): If empty, set to null.
2997 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
2998 same code path here to resolve constants names that we did have in
2999 MemberAccess.DoResolve. There is too much code duplicated here.
3001 2002-04-01 Miguel de Icaza <miguel@ximian.com>
3003 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
3005 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
3008 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
3009 tokens, numbers and strings.
3011 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
3014 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
3015 asyncronous parameters and the regular parameters.
3017 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
3018 specify the target directory.
3020 * expression.cs: (This.DoResolve): Simplify
3021 (As.Emit): Optimize, do not generate IsInst if the expression is
3022 always of the given type.
3024 (Is.DoResolve): Bug fix, we were reporting both always/never for
3027 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
3028 creating too many unnecessary arrays.
3030 2002-03-31 Miguel de Icaza <miguel@ximian.com>
3032 * class.cs (EmitFieldInitializer): Use Assign expression to assign
3033 fields instead of rolling our own initializer. Takes care of all
3034 implicit conversions, and drops unnecessary static checks/argument.
3036 2002-03-31 Dick Porter <dick@ximian.com>
3038 * driver.cs: use the GetDirectories() return values properly, and
3039 use "/" as path separator.
3041 2002-03-30 Miguel de Icaza <miguel@ximian.com>
3043 * expression.cs (Unary): Optimize - - expr into expr.
3044 (Binary): Optimize a + (-b) into a -b.
3046 * codegen.cs (CodeGen): Made all methods static.
3048 2002-03-29 Miguel de Icaza <miguel@ximian.com>
3052 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
3053 TypeBuilder property.
3055 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
3058 * tree.cs: Removed the various RecordXXXX, and replaced with a
3059 single RecordDecl. Removed all the accessor methods, and just
3060 left a single access point Type
3062 * enum.cs: Rename DefineEnum to DefineType.
3064 * decl.cs: New abstract method `DefineType' used to unify the
3065 Defines for Enumerations, Interfaces, TypeContainers and
3068 (FindType): Moved LookupInterfaceOrClass here. Moved the
3069 LookupBaseClasses method that used to live in class.cs and
3070 interface.cs here, and renamed to FindType.
3072 * delegate.cs: Implement DefineType. Take advantage of the
3073 refactored pattern for locating the parent builder without taking
3074 the parent_builder argument (which we know does not work if we are
3075 nested, and triggering a toplevel definition).
3077 2002-03-28 Miguel de Icaza <miguel@ximian.com>
3079 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
3080 accessibility of a member has changed during override and report
3083 * class.cs (Method.Define, Property.Define): Only complain on
3084 overrides if the method is private, any other accessibility is
3085 fine (and since we just checked the permission is the same, we are
3088 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
3089 and elif are processed always. The other pre-processing
3090 directives are only processed if we are "taking" the path
3092 2002-03-29 Martin Baulig <martin@gnome.org>
3094 * class.cs (Method.Emit): Only emit symbolic debugging info if the
3095 current location is not Null.
3097 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
3098 a separate method so we can profile it.
3100 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
3101 `span.Seconds' are just seconds, but no minutes or hours.
3102 (MainDriver): Profile the CodeGen.SaveSymbols calls.
3104 2002-03-28 Miguel de Icaza <miguel@ximian.com>
3106 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
3107 Remove the gratuitous set of Final:
3109 // If an interface implementation, then we can set Final.
3110 if (((flags & MethodAttributes.Abstract) == 0) &&
3111 implementing.DeclaringType.IsInterface)
3112 flags |= MethodAttributes.Final;
3114 I do not know what I was smoking when I used that.
3117 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
3118 step into fixing the name resolution issues for delegates and
3119 unifying the toplevel name resolution.
3121 2002-03-28 Martin Baulig <martin@gnome.org>
3123 * class.cs (Method.Emit): If we have a symbol writer, call its
3124 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
3125 tell it about the current method.
3127 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
3128 writer that we're going to emit the first byte of IL code for a new
3129 statement (a new source line).
3130 (EmitContext.EmitTopBlock): If we have a symbol writer, call
3131 EmitContext.Mark() before emitting any code.
3133 * location.cs (SymbolDocument): Return null when we're Null.
3135 * statement.cs (Statement): Moved the `Location loc' variable here.
3136 (Statement.EmitBoolExpression): If we have a symbol writer, call
3137 ec.Mark() before emitting any code to tell it that we're at the
3138 beginning of a new statement.
3139 (StatementExpression): Added `Location' argument to the constructor.
3140 (Block): Added public readonly variable `StartLocation' and public
3141 variable `EndLocation'. The latter is to be set using SetEndLocation().
3142 (Block): Added constructor which takes a start and end location.
3143 (Block.SetEndLocation): New method. This sets the end location.
3144 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
3145 local variables we create.
3146 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
3147 each statement and do also mark the begin and end of the block.
3149 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
3150 tell it the current lexer.Location, use Location.Null for the end of the
3152 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
3153 current block, set its end location using SetEndLocation().
3154 (statement_expression): StatementExpression constructor now takes the
3155 lexer.Location as additional argument.
3156 (for_statement, declare_local_variables): Likewise.
3157 (declare_local_variables): When creating a new implicit block, use the
3158 new Block constructor and pass it the lexer.Location.
3160 2002-03-28 Miguel de Icaza <miguel@ximian.com>
3162 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
3163 members also on the parent interfaces recursively.
3165 2002-03-27 Miguel de Icaza <miguel@ximian.com>
3167 * report.cs: Use new formats, since Gonzalo finished the missing
3170 * expression.cs (Binary.ResolveOperator): added missing operator|
3171 operator& and operator^ for bool/bool.
3173 * cs-parser.jay: CheckDef now takes a Location argument that is
3174 used to report errors more precisly (instead of reporting the end
3175 of a definition, we try to track something which is a lot closer
3176 to the source of the problem).
3178 * cs-tokenizer.cs: Track global token use, so we can properly flag
3179 the use of #define/#undef after the first token has been seen.
3181 Also, rename the reportXXXX to Error_DescriptiveName
3183 * decl.cs (DeclSpace.IsTopLevel): Move property here from
3184 TypeContainer, so that Enum and Interface can use this too.
3186 * class.cs (TypeContainer.LookupInterfaceOrClass,
3187 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
3188 `builder' argument. Typically this was used to pass the parent
3189 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
3192 The problem is that a nested class could trigger the definition of
3193 a toplevel class, and the builder would be obviously wrong in that
3196 So we drop this argument, and we compute dynamically the
3197 TypeBuilder/ModuleBuilder (the correct information was available
3198 to us anyways from DeclSpace.Parent)
3200 * interface.cs (Interface.DefineInterface): Drop builder
3201 parameter cleanup like class.cs
3203 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
3206 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
3209 (Try.Emit): Propagate the returns value from the statement.
3211 (Return.Emit): Even if we are leavning
3213 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
3215 * modifiers.cs: Fix the computation of MethodAttributes flags.
3217 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
3219 * driver.cs: allow compilation of files that start with '/'.
3220 Add a default case when checking the argument of --target.
3222 2002-03-25 Miguel de Icaza <miguel@ximian.com>
3224 * interface.cs: Implement the same search algorithm for types in
3227 * delegate.cs: Do not allow multiple definition.
3229 * Recovered ChangeLog that got accidentally amputated
3231 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
3233 * rootcontext.cs: Load manually enum to allow core classes to
3234 contain enumerations.
3236 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
3237 Update to new static methods in TypeManager.
3239 * typemanager.cs (GetMethod, GetConstructor): Use our
3240 implementation of FindMembers to find the members, since during
3241 corlib compilation, the types are TypeBuilders and GetMethod and
3242 GetConstructor do not work.
3244 Make all methods in TypeManager static.
3246 (InitCodeHelpers): Split the functionality from
3247 the InitCodeTypes function.
3249 * driver.cs: Call InitCodeHelpers after we have populated the
3252 * cs-parser.jay (delegate_declaration): we did not used to compute
3253 the delegate name correctly for void delegates.
3255 2002-03-24 Miguel de Icaza <miguel@ximian.com>
3257 * rootcontext.cs (RootContext): Init the interface_resolve_order
3258 and type_container_resolve_order always.
3260 (ResolveCore, BootstrapCorlib_ResolveClass,
3261 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
3262 compiler when compiling with --nostdlib
3264 * class.cs (TypeContainer.DefineType): Check that our parent is
3265 not null. This test is most important when we are bootstraping
3268 * codegen.cs: Split out the symbol writing code.
3270 2002-03-25 Martin Baulig <martin@gnome.org>
3272 * driver.cs (-g): Made -g an alias for --debug.
3274 2002-03-24 Martin Baulig <martin@gnome.org>
3276 * codegen.cs (SymbolWriter): New public variable. Returns the
3277 current symbol writer.
3278 (CodeGen): Added `bool want_debugging_support' argument to the
3279 constructor. If true, tell the ModuleBuild that we want debugging
3280 support and ask it for the ISymbolWriter.
3281 (Save): If we have a symbol writer, call it's Close() method after
3282 saving the assembly.
3284 * driver.c (--debug): New command line argument to create a
3285 debugger information file.
3287 * location.cs (SymbolDocument): New public property. Returns an
3288 ISymbolDocumentWriter object for the current source file or null
3289 if we don't have a symbol writer.
3291 2002-03-21 Miguel de Icaza <miguel@ximian.com>
3293 * driver.cs (LoadAssembly): Correctly return when all the paths
3294 have been tried and not before.
3296 * statement.cs (Switch.Emit): return the actual coverage for this
3297 statement (returns/not-returns)
3299 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
3300 switch of the statement if we are the last switch section. That
3301 kills two problems: try/catch problems (we used to emit an empty
3302 nop at the end) and switch statements where all branches would
3305 2002-03-19 Miguel de Icaza <miguel@ximian.com>
3307 * driver.cs: Add default assemblies (the equivalent to the
3308 Microsoft CSC.RSP file)
3310 * cs-tokenizer.cs: When updating `cols and setting it to zero,
3311 also update tokens_seen and set it to false.
3313 * driver.cs: Implement --recurse for Mike.
3315 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
3316 correctly splitting out the paths.
3318 2002-03-18 Miguel de Icaza <miguel@ximian.com>
3320 * interface.cs (Interface.PopulateProperty): Instead of using
3321 `parent' as the declaration space for the set parameters, use
3324 * support.cs (InternalParameters): InternalParameters constructor
3325 takes a DeclSpace instead of a TypeContainer.
3327 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
3328 types are being initialized, load the address of it before calling
3331 (New): Provide a mechanism to disable the generation of local
3332 value type temporaries when the caller will be providing us with
3333 an address to store it.
3335 (ArrayCreation.EmitDynamicInitializers): Use it.
3337 2002-03-17 Miguel de Icaza <miguel@ximian.com>
3339 * expression.cs (Invocation.EmitArguments): Only probe for array
3340 property if there is more than one argument. Sorry about that.
3342 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
3345 * class.cs (Method.LabelParameters): Fix incorrect code path that
3346 prevented the `ParamArrayAttribute' from being applied to the
3349 2002-03-16 Miguel de Icaza <miguel@ximian.com>
3351 * support.cs (ReflectionParameters): Correctly compute whether the
3352 last argument is a params array. Fixes the problem with
3355 * typemanager.cs: Make the assemblies array always be non-null
3356 (empty, but non-null)
3358 * tree.cs (RecordDecl): New function that abstracts the recording
3359 of names. This reports error 101, and provides a pointer to the
3360 previous declaration. Fixes a crash in the compiler.
3362 * cs-parser.jay (constructor_declaration): Update to new grammar,
3363 and provide a constructor_body that can be empty.
3365 2002-03-15 Miguel de Icaza <miguel@ximian.com>
3367 * driver.cs: Add support for --resources.
3369 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
3370 Make all types for the various array helper methods be integer.
3372 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
3373 CheckState to ConvCast.
3375 (ConvCast): Now it takes a `checked' state argument, to avoid
3376 depending on the emit context for the conversion, and just using
3377 the resolve time setting.
3379 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
3380 instead of Invocation.EmitArguments. We do not emit the original
3381 arguments, instead we emit those which have been converted to
3382 unsigned int expressions.
3384 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
3386 * codegen.cs: ditto.
3388 * expression.cs (LocalVariableReference): Drop the use of the
3389 Store function that depended on the variable index.
3391 * statement.cs (VariableInfo): Drop the `Idx' property from this
3392 class, as this is not taking into account the indexes for
3393 temporaries tat we generate during the execution, getting the
3396 * class.cs: First emit class initializers, then call the parent
3399 * expression.cs (Binary): Fix opcode emision.
3400 (UnaryMutator.EmitCode): Support checked code generation
3402 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
3403 matches for events for both the Static and Instance scans,
3404 pointing to the same element. Fix that.
3406 2002-03-14 Miguel de Icaza <miguel@ximian.com>
3408 * rootcontext.cs (ResolveTree): Always set the
3409 interface_resolve_order, because nested interfaces will be calling
3412 * class.cs (GetInterfaceOrClass): Track the same resolution
3413 process used by TypeManager.LookupType. This fixes the nested
3414 type lookups in class declarations (separate path from
3417 (TypeContainer.DefineType): Also define nested interfaces.
3418 (TypeContainer.RegisterOrder): New public function used to
3419 register the order in which child interfaces need to be closed.
3421 Nested interfaces need to be closed after their parents have been
3424 * interface.cs (InterfaceAttr): Put all the logic for computing
3425 the interface attribute here.
3427 (DefineInterface): Register our interface order with the
3428 RootContext or with the TypeContainer depending on the case.
3430 2002-03-12 Miguel de Icaza <miguel@ximian.com>
3432 * cs-parser.jay: rework foreach statement to work with the new
3433 changes to the policy on SimpleNames.
3435 * report.cs: support Stacktrace on warnings as well.
3437 * makefile: drop --unsafe and /unsafe from the compile.
3439 2002-03-13 Ravi Pratap <ravi@ximian.com>
3441 * ecore.cs (StandardConversionExists): Modify to take an Expression
3442 as the first parameter. Ensure we do null -> reference type conversion
3445 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
3446 temporary Expression objects.
3448 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
3450 * interface.cs: workaround bug in method overloading resolution
3451 (there is already a bugzilla bug for it).
3453 2002-03-12 Miguel de Icaza <miguel@ximian.com>
3455 We could also solve this problem by having a separate path for
3456 performing type lookups, instead of DoResolve, we could have a
3457 ResolveType entry point, and only participating pieces of the
3458 production (simplename, deref, array) would implement this.
3460 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
3461 signal SimpleName to only resolve type names and not attempt to
3462 resolve anything else.
3464 * expression.cs (Cast): Set the flag.
3466 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
3468 * class.cs: Only report 108 if there is no `new' modifier.
3470 * cs-parser.jay: rework foreach statement to work with the new
3471 changes to the policy on SimpleNames.
3473 * report.cs: support Stacktrace on warnings as well.
3475 * makefile: drop --unsafe and /unsafe from the compile.
3477 2002-03-11 Miguel de Icaza <miguel@ximian.com>
3479 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
3480 lookups here, instead of doing that at parse time. This means
3481 that our grammar will not introduce `LocalVariableReferences' as
3482 expressions at this point. That solves the problem of code like
3490 This is only half the fix. The full fix requires parameters to
3491 also be handled in this way.
3493 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
3494 makes the use more obvious of the DeclSpace. The
3495 ec.TypeContainer.TypeBuilder is now only used to pull the
3498 My theory is that I can get rid of the TypeBuilder completely from
3499 the EmitContext, and have typecasts where it is used (from
3500 DeclSpace to where it matters).
3502 The only pending problem is that the code that implements Aliases
3503 is on TypeContainer, and probably should go in DeclSpace.
3505 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
3506 lookups here, instead of doing that at parse time. This means
3507 that our grammar will not introduce `LocalVariableReferences' as
3508 expressions at this point. That solves the problem of code like
3516 This is only half the fix. The full fix requires parameters to
3517 also be handled in this way.
3519 * class.cs (Property.DefineMethod): When implementing an interface
3520 method, set newslot, when implementing an abstract method, do not
3521 set the flag (before we tried never setting it, or always setting
3522 it, which is the difference).
3523 (Indexer.DefineMethod): same.
3524 (Method.DefineMethod): same.
3526 * ecore.cs: Only set the status used flag if we get back a Field.
3528 * attribute.cs: Temporary hack, so Paolo can keep working.
3530 2002-03-08 Ravi Pratap <ravi@ximian.com>
3532 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
3533 the unmanaged type in the case we have a MarshalAs attribute.
3535 (Resolve): Handle the case when we are parsing the special MarshalAs
3536 attribute [we need to store the unmanaged type to use later]
3538 * typemanager.cs (marshal_as_attr_type): Built in type for the
3539 MarshalAs Attribute.
3541 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
3542 on parameters and accordingly set the marshalling info.
3544 2002-03-09 Miguel de Icaza <miguel@ximian.com>
3546 * class.cs: Optimizing slightly by removing redundant code after
3547 we switched to the `NoTypes' return value.
3548 (Property.DefineMethod): use NoTypes here too.
3550 This fixes the bug I introduced in my last batch of changes.
3552 2002-03-05 Ravi Pratap <ravi@ximian.com>
3554 * tree.cs (RecordEnum): Add. We now keep track of enums too.
3556 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
3557 Enums since those are types too.
3559 * cs-parser.jay (enum_declaration): Record enums as we parse them.
3561 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
3562 thanks to a call during the lookup process.
3564 2002-03-07 Miguel de Icaza <miguel@ximian.com>
3566 * statement.cs (Foreach): Lots of work to accomodate a particular
3567 kind of foreach statement that I had not kept in mind. It is
3568 possible to have foreachs on classes that provide a GetEnumerator
3569 method that return objects that implement the "pattern" for using
3570 a foreach, there is no need to support GetEnumerator
3573 This is needed to compile nant.
3575 * decl.cs: Only report 114 if the member is not `Finalize' and if
3576 the warning level is at least 2.
3578 * class.cs: Moved the compare function from Method to
3581 (MethodSignature.InheritableMemberSignatureCompare): Add new
3582 filter function that is used to extract inheritable methods from a
3585 (Method.Define): Use the new `inheritable_method_signature_filter'
3588 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
3591 2002-03-06 Miguel de Icaza <miguel@ximian.com>
3593 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
3595 * cs-parser.jay: Add opt_semicolon to the interface declaration.
3597 * expression.cs: Pass location information to
3598 ConvertImplicitStandard.
3600 * class.cs: Added debugging code to track return values from
3603 2002-03-05 Miguel de Icaza <miguel@ximian.com>
3605 * expression.cs (Is.DoResolve): If either side of the `is' is an
3606 interface, do not flag the warning.
3608 * ecore.cs (ImplicitReferenceConversion): We need a separate test
3611 * report.cs: Allow for --fatal to be used with --probe.
3613 * typemanager.cs (NoTypes): Move the definition for the empty Type
3616 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
3618 (TypeContainer.DefineProxy): New function used to proxy to parent
3619 implementations when implementing interfaces.
3620 (TypeContainer.ParentImplements): used to lookup if our parent
3621 implements a public function that is required by an interface.
3622 (TypeContainer.VerifyPendingMethods): Hook this up.
3624 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
3625 `modules' and `assemblies' arraylists into arrays. We only grow
3626 these are the very early start up of the program, so this improves
3627 the speedof LookupType (nicely measured).
3629 * expression.cs (MakeByteBlob): Replaced unsafe code with
3630 BitConverter, as suggested by Paolo.
3632 * cfold.cs (ConstantFold.Binary): Special case: perform constant
3633 folding of string concatenation, but if either side is a string,
3634 and the other is not, then return null, and let the runtime use
3635 the concatenation on the string plus the object (using
3638 2002-03-04 Miguel de Icaza <miguel@ximian.com>
3640 Constant Folding has been implemented now.
3642 * expression.cs (Unary.Reduce): Do not throw an exception, catch
3643 the error instead on types that are not supported in one's
3646 * constant.cs (Constant and all children): New set of functions to
3647 perform implict and explicit conversions.
3649 * ecore.cs (EnumConstant): Implement the new functions to perform
3650 conversion by proxying to the child expression.
3652 * codegen.cs: (ConstantCheckState): Constant evaluation has its
3653 own separate setting that can not be turned off from the command
3654 line using --unchecked or --checked and is only controlled using
3655 the checked/unchecked statements and expressions. This setting is
3656 used by the constant folder to flag errors.
3658 * expression.cs (CheckedExpr, UncheckedExpr): Set the
3659 ConstantCheckState as well.
3661 During Resolve, they also have to flag the state, because the
3662 constant folder runs completely in the Resolve phase.
3664 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
3667 2002-03-01 Miguel de Icaza <miguel@ximian.com>
3669 * cfold.cs: New file, this file contains the constant folder.
3671 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
3672 argument to track whether we are using the resulting address to
3673 load or store a value and provide better error messages.
3675 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
3676 new AddressOf arguments.
3678 * statement.cs (Foreach.EmitCollectionForeach): Update

3693 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
3696 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
3697 essentially like methods and apply attributes like MethodImplOptions to them too.
3699 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
3702 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
3703 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
3706 * Update code everywhere accordingly.
3708 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
3710 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
3712 2002-02-28 Ravi Pratap <ravi@ximian.com>
3714 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
3715 try performing lookups against those instead of jumping straight into using
3716 the 'using' clauses.
3718 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
3720 (LookupType): Perform lookups in implicit parents too.
3722 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
3723 sequence as RootContext.LookupType.
3725 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
3726 the various cases of namespace lookups into this method.
3728 2002-03-01 Miguel de Icaza <miguel@ximian.com>
3730 * cs-parser.jay: Add support for [Attribute ()] (empty arguments

3748 2002-02-26 Miguel de Icaza <miguel@ximian.com>
3750 * expression.cs: Special case the `null' object when trying to
3751 auto-compute the type, as anything can be explicitly converted to
3754 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
3755 spotting this Paolo.
3757 (Expression.ImplicitNumericConversion): Perform comparissions of
3758 the type using the underlying type in the case of an enumeration
3759 rather than using the enumeration type for the compare.
3761 Cope with the underlying == type case, which is not possible to
3764 (Expression.ConvertNumericExplicit): Perform comparissions of
3765 the type using the underlying type in the case of an enumeration
3766 rather than using the enumeration type for the compare.
3768 * driver.cs: If the user does not supply an extension, assume .exe
3770 * cs-parser.jay (if_statement): Rewrote so that we can track the
3771 location for the if statement.
3773 * expression.cs (Binary.ConstantFold): Only concat strings when
3774 the operation is "+", not everything ;-)
3776 * statement.cs (Statement.EmitBoolExpression): Take a location
3778 (If, While, Do): Track location.
3780 * expression.cs (Binary.ResolveOperator): In the object + string
3781 case, I was missing a call to ConvertImplicit
3783 2002-02-25 Ravi Pratap <ravi@ximian.com>
3785 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
3786 Location arguments. Ensure we use RootContext.LookupType to do our work
3787 and not try to do a direct Type.GetType and ModuleBuilder.GetType
3789 * interface.cs (PopulateMethod): Handle the type of the parameter being
3792 * expression.cs (Invocation.BetterFunction): Handle the case when we
3793 have a params method with no fixed arguments and a call is made with no

3806 duplicating the name of the variable parameter.
3807 (GetParameterByName): Fix bug where we were not looking up array
3808 paramters if they were the only present (thanks Paolo!).
3809 (GetParameterInfo): We only have an empty set of types if both
3810 fixed and array are set to null.
3811 (GetParameterInfo-idx): Handle FixedParameter == null
3813 * cs-parser.jay: Handle the case where there is no catch
3814 statements (missing null test).

3818 * driver.cs (MainDriver): Be conservative on our command line
3821 Catch DirectoryNotFoundException when calling GetFiles.
3823 (SplitPathAndPattern): Used to split the input specification into

3828 * statement.cs (Fixed): Implement the last case of the Fixed
3829 statement (string handling).

3836 * expression.cs (Binary.ResolveOperator): Remove redundant
3837 MemberLookup pn parent type.
3838 Optimize union call, we do not need a union if the types are the same.
3839 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
3842 Specialize the use of MemberLookup everywhere, instead of using
3843 the default settings.
3845 (StackAlloc): Implement stackalloc keyword.
3847 * cs-parser.jay: Add rule to parse stackalloc.
3849 * driver.cs: Handle /h, /help, /?

3867 * statement.cs (Fixed): Implement fixed statement for arrays, we
3868 are missing one more case before we are done.
3870 * expression.cs (Indirection): Implement EmitAssign and set the
3871 ExprClass to Variable. This allows pointer dereferences to be
3872 treated as variables, and to have values assigned to them.
3874 * ecore.cs (Expression.StoreFromPtr): New utility function to
3875 store values dereferencing.
3877 2002-02-20 Ravi Pratap <ravi@ximian.com>
3879 * expression.cs (Binary.ResolveOperator): Ensure that we are
3880 not trying to operate on a void type - this fixes the reported
3883 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
3884 the parent implementation is sealed.
3886 * ../errors/cs0239.cs : Add.
3888 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
3890 * typemanager.cs (unverifiable_code_type): Corresponds to
3891 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
3892 which have unsafe code in them.
3894 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
3897 2002-02-19 Miguel de Icaza <miguel@ximian.com>

3922 statement for the &x case.
3924 2002-02-14 Miguel de Icaza <miguel@ximian.com>
3926 * class.cs (Property.Define, Method.Define): Remove newslot when
3929 * modifiers.cs: My use of NewSlot when `Abstract' was set was
3930 wrong. NewSlot should only be used if the `new' keyword is present.
3932 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
3933 locating our system dir. Sorry about this.
3935 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3937 * driver.cs (GetSystemDir): Compute correctly the location of our
3938 system assemblies. I was using the compiler directory instead of
3939 the library directory.
3941 2002-02-13 Ravi Pratap <ravi@ximian.com>
3943 * expression.cs (BetterFunction): Put back in what Miguel commented out
3944 since it is the correct fix. The problem is elsewhere ;-)
3946 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
3947 parameters of the parms method are themselves compatible or not !
3949 (StandardConversionExists): Fix very dangerous bug where we were forgetting
3950 to check that a class implements an interface before saying that an implicit
3951 conversion was allowed. Use ImplementsInterface to do the checking.
3953 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3955 * class.cs (Method.Define): Track whether we are an explicit
3956 implementation or not. And only call DefineMethodOverride if we
3957 are an explicit implementation.
3959 (Property.DefineMethod): Ditto.
3961 2002-02-11 Ravi Pratap <ravi@ximian.com>
3963 * expression.cs (BetterFunction): Catch hideous bug which was
3964 preventing us from detecting ambiguous calls due to implicit casts i.e
3967 2002-01-29 Miguel de Icaza <miguel@ximian.com>
3969 * support.cs (Pair): Remove un-needed method. I figured why I was
3970 getting the error in cs-parser.jay, the variable in a foreach loop
3971 is readonly, and the compiler does not really treat this as a variable.
3973 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
3974 instead of EQUALS in grammar.
3976 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
3978 * expression.cs (Unary.DoResolve): Check whether the argument is
3981 2002-01-28 Miguel de Icaza <miguel@ximian.com>
3983 * support.cs: Api for Pair to set a value. Despite the fact that
3984 the variables are public the MS C# compiler refuses to compile
3985 code that accesses the field if the variable is part of a foreach
3988 * statement.cs (Fixed): Begin implementation of the fixed
3991 (Block.AddVariable): Return the VariableInfo on success and null
3992 on failure instead of true/false.

3995 defined (we were ignoring this value before) and properly unwind
3998 (fixed_statement): grammar for the fixed statement.
4000 2002-01-25 Miguel de Icaza <miguel@ximian.com>
4002 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also

4017 use in non-unsafe context).
4019 (SimpleName.DoResolve): Check for pointers in field access on safe
4022 (Expression.LoadFromPtr): Factor the load-indirect code in this
4023 function. This was duplicated in UnboxCast and ParameterReference
4025 2002-01-24 Miguel de Icaza <miguel@ximian.com>
4027 * expression.cs (ComposedCast): report an error if a pointer cast
4028 is used in a safe region.
4030 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
4031 pointer type casts in unsafe context.
4033 * codegen.cs (EmitContext): Set up IsUnsafe.
4035 * cs-parser.jay (non_expression_type): Add productions for pointer
4038 * expression.cs (Invocation.EmitCall): Remove chunk of buggy

4042 * statement.cs (Do.Emit, While.Emit, For.Emit,
4043 Statement.EmitBoolExpression): Add support to Do and While to
4044 propagate infinite loop as `I do return' semantics.
4046 Improve the For case to also test for boolean constants.
4048 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
4049 to the list of attributes we can add.
4051 Remove `EmitContext' argument.
4053 * class.cs (Method.Define): Apply parameter attributes.
4054 (Constructor.Define): Apply parameter attributes.
4055 (MethodCore.LabelParameters): Move here the core of labeling
4058 * support.cs (ReflectionParameters.ParameterModifier,
4059 InternalParameters.ParameterModifier): Use IsByRef on the type and
4060 only return the OUT bit for these parameters instead of in/out/ref
4063 This is because I miss-understood things. The ParameterInfo.IsIn
4064 and IsOut represent whether the parameter has the [In] and [Out]
4067 2002-01-22 Miguel de Icaza <miguel@ximian.com>
4069 * ecore.cs (FieldExpr.Emit): Release temporaries.

4073 * codegen.cs (EmitContext.GetTemporaryStorage,
4074 EmitContext.FreeTemporaryStorage): Rework the way we deal with

4078 2002-01-21 Miguel de Icaza <miguel@ximian.com>
4080 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
4081 need to make a copy of the variable to generate verifiable code.
4083 2002-01-19 Miguel de Icaza <miguel@ximian.com>
4085 * driver.cs: Compute dynamically the system directory.
4087 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
4088 Slower, but more generally useful. Used by the abstract
4089 registering implementation.
4091 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
4092 the rules for the special rule on Type/instances. First check if
4093 we have the same name, and if so, try that special static path
4094 rather than the instance path.
4096 2002-01-18 Miguel de Icaza <miguel@ximian.com>
4098 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
4101 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
4102 Enum, ValueType, Delegate or Array for non-corlib compiles.

4106 * typemanager.cs (IndexerPropetyName): Ravi never tested this
4109 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
4110 fix, we were returning too early, so we were not registering
4111 pending methods from abstract classes.
4113 Do not register pending methods if the class is abstract.
4115 * expression.cs (Conditional.DoResolve): Report circular implicit
4116 conversions when we neecd to compute it for conditional
4119 (Is.DoResolve): If the expression is always of the provided type,
4120 flag warning 183. If the expression can not ever be of the
4121 provided type flag warning 184.
4123 * class.cs: Catch 169 as well.
4125 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
4128 2002-01-18 Nick Drochak <ndrochak@gol.com>

4132 2002-01-17 Miguel de Icaza <miguel@ximian.com>
4134 * interface.cs: (PopulateMethod): Check for pointers being defined
4135 only if the unsafe context is active.
4136 (PopulateProperty): ditto.
4137 (PopulateIndexer): ditto.
4139 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be

4148 hashtable if there are classes or structs defined.
4150 * expression.cs (LocalVariableReference.DoResolve): Simplify this
4151 code, as the constant resolution moved.
4153 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
4154 the metadata, so we can flag error 133.
4156 * decl.cs (MemberCore.UnsafeOK): New function to test that a
4157 pointer is being declared in an unsafe context.
4159 2002-01-16 Miguel de Icaza <miguel@ximian.com>
4161 * modifiers.cs (Modifiers.Check): Require a Location argument.
4162 Report error 227 for Unsafe use.
4164 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
4166 * statement.cs (For.Emit): If the test is null, then report that
4167 we do `return', as we wont reach anything afterwards.
4169 (Switch.SwitchGoverningType): Track the expression that matched
4172 * driver.cs: Allow negative numbers as an error code to flag.
4174 * cs-parser.jay: Handle 1551.

4194 access not allowed in static code)
4196 2002-01-11 Ravi Pratap <ravi@ximian.com>
4198 * typemanager.cs (IsPointerType): Utility method which we are going
4201 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
4202 the object type, so we take care of that.
4204 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
4206 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
4207 added to non-params parameters :-)
4209 * typemanager.cs (CSharpName): Include 'void' type too.
4211 (void_ptr_type): Include in the set of core types.
4213 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
4216 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
4219 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
4220 completely forgotten about it.
4222 2002-01-10 Ravi Pratap <ravi@ximian.com>
4224 * cs-parser.jay (pointer_type): Add. This begins our implementation
4225 of parsing rules for unsafe code.
4227 (unsafe_statement): Implement.
4229 (embedded_statement): Modify to include the above.
4231 * statement.cs (Unsafe): Implement new class for unsafe blocks.
4233 * codegen.cs (EmitContext.InUnsafe): Add. This determines
4234 if the current context is an unsafe one.
4236 * cs-parser.jay (local_variable_pointer_type): Since local variable types
4237 are handled differently, we need separate rules for them.
4239 (local_variable_declaration): Update to use local_variable_pointer_type
4240 to allow variable declarations of unmanaged pointer types.
4242 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
4245 * ../errors/cs0214.cs : Add.
4247 2002-01-16 Nick Drochak <ndrochak@gol.com>

4265 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
4268 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
4269 this routine and will wrap the call in a try/catch block. Deal
4272 2002-01-11 Miguel de Icaza <miguel@ximian.com>
4274 * ecore.cs (Expression.MemberLookup): instead of taking a
4275 parameter `same_type' that was used to tell whether we could
4276 access private members we compute our containing type from the
4279 (FieldExpr): Added partial support for volatile fields. This does
4280 not work for volatile fields exposed from assemblies, as I can not
4281 figure out how to extract the modreq from it.
4283 Updated all the source files to use this.
4285 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
4286 because it is referenced by MemberLookup very often.
4288 2002-01-09 Ravi Pratap <ravi@ximian.com>
4290 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
4291 TypeBuilder.GetCustomAttributes to retrieve what we need.
4293 Get rid of redundant default_member_attr_type as this is the same as
4294 default_member_type which already exists.
4296 * interface.cs, attribute.cs : Update accordingly.
4298 2002-01-08 Miguel de Icaza <miguel@ximian.com>
4300 * typemanager.cs: Enable IndexerPropertyName again. It does not
4301 work for TYpeBuilders though. Ravi, can you please fix this?
4303 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
4305 * expression.cs (Argument.Emit): Handle the case of ref objects
4306 being passed to ref functions;
4308 (ParameterReference.EmitLoad): Loads the content of the pointer
4309 without dereferencing.
4311 2002-01-07 Miguel de Icaza <miguel@ximian.com>
4313 * cs-tokenizer.cs: Implemented the pre-processing expressions.
4315 2002-01-08 Ravi Pratap <ravi@ximian.com>
4317 * class.cs (Indexer.DefineMethod): Incorporate the interface
4318 type in the name of the method if we are doing explicit interface
4321 * expression.cs (ConversionExists): Remove as it is completely obsolete.
4323 (BetterConversion): Fix extremely trivial bug where we were referring to
4324 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
4327 * ../errors/bug16.cs : Add although we have fixed it.
4329 2002-01-07 Miguel de Icaza <miguel@ximian.com>
4331 * expression.cs (BaseIndexer): Begin implementation.
4333 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
4335 * cs-parser.jay (indexer_declarator): Use qualified_identifier
4336 production directly to remove a shift/reduce, and implement
4337 explicit interface implementation.
4339 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
4340 after a floating point suffix.
4342 * expression.cs (DoNumericPromotions): Improved the conversion for
4343 uint/uint. If we have a constant, we avoid doing a typecast to a
4346 * class.cs (Indexer): Implement explicit interface implementation
4349 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
4351 * class.cs: make the default instance constructor public and hidebysig.
4353 2001-01-03 Ravi Pratap <ravi@ximian.com>
4355 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
4356 so we can call it from elsewhere.
4358 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
4359 we emit it internally if the class has a defined indexer; otherwise the user
4360 emits it by decorating the class definition with the DefaultMemberAttribute.
4362 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
4363 attribute is not used on a type which defines an indexer.
4365 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
4366 character when we skip whitespace.
4368 * ../errors/cs0646.cs : Add.
4370 2002-01-03 Miguel de Icaza <miguel@ximian.com>
4372 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
4375 * makefile: Add practical target `mcs3.exe' which builds the third
4376 generation compiler.
4378 * expression.cs (New): Fix structures constructor calling.
4380 * class.cs (Property, Method, Indexer): Emit Final flag on the
4381 method if we are an interface implementation and we are not
4384 * ecore.cs (PropertyExpr): New public field `IsBase', tells
4385 whether this property is referencing a `base' method.
4387 * expression.cs (Invocation.EmitCall): take an extra argument:
4388 is_base, this is used to determine whether the `call' or
4389 `callvirt' opcode should be used.
4392 * delegate.cs: update EmitCall.
4394 * class.cs (Method.Define): Set NewSlot for the cases where we are
4395 not implementing an interface method.
4397 (Property.Define): ditto.
4399 2002-01-02 Miguel de Icaza <miguel@ximian.com>
4401 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
4402 'r'. Allows mcs to parse itself fully.
4404 2002-01-02 Ravi Pratap <ravi@ximian.com>
4406 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
4407 of the number of initializers that require the InitializeArray method.
4409 (CheckIndices): Store the Expression in all cases - not the plain value. Also
4410 update the above field where necessary.
4412 (MakeByteBlob): Update accordingly.
4414 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
4417 (EmitDynamicInitializers): Update in accordance with the new optimization.
4419 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
4420 same OpCode applies.
4422 * cs-parser.jay : Fix some glaring errors I introduced.
4424 2002-01-01 Ravi Pratap <ravi@ximian.com>
4426 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
4427 so that we can check for name clashes there too.
4429 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
4430 for interface indexers.
4432 * interfaces.cs (Define): Emit the default member attribute.
4434 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
4435 variable was being referred to while setting the value ;-)
4437 2002-01-01 Miguel de Icaza <miguel@ximian.com>
4439 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
4440 byte-by-byte information when we know the data is zero.
4442 Make the block always a multiple of 4, because
4443 DefineInitializedData has a bug.
4445 * assign.cs: Fix, we should assign from the temporary, not from
4448 * expression.cs (MakeByteBlob): Fix my incorrect code.
4450 2001-12-31 Miguel de Icaza <miguel@ximian.com>
4452 * typemanager.cs (EnumToUnderlying): This function is used to get
4453 the underlying type from an enumeration, because it does not
4456 * constant.cs: Use the I4_S form for values between -128 and 127.
4458 * statement.cs (Block.LookupLabel): Looks up a label.
4459 (Block): Drop support for labeled blocks.
4461 (LabeledStatement): New kind of statement that represents a label
4464 (Goto): Finally implement this bad boy.
4466 * cs-parser.jay: Update to reflect new mechanism to implement
4469 2001-12-30 Miguel de Icaza <miguel@ximian.com>
4471 * codegen.cs (EmitContext.This): a codegen property that keeps the
4472 a single instance of this instead of creating many different this
4475 * delegate.cs (Delegate.DoResolve): Update to use the property;
4477 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
4479 * expression.cs (BaseAccess.DoResolve): Ditto.
4481 2001-12-29 Ravi Pratap <ravi@ximian.com>
4483 * typemanager.cs (methodimpl_attr_type): Add to hold the type
4484 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
4486 (InitCoreTypes): Update accordingly.
4488 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
4489 so we can quickly store the state.
4491 (ApplyAttributes): Set the correct implementation flags
4492 for InternalCall methods.
4494 2001-12-29 Miguel de Icaza <miguel@ximian.com>
4496 * expression.cs (EmitCall): if a method is not virtual, then do
4497 not use callvirt on it.
4499 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
4500 user defined stuff) requires the use of stobj, which takes an
4501 address on the stack instead of an array and an index. So emit
4502 the Ldelema operation for it.
4504 (EmitStoreOpcode): Use stobj for valuetypes.
4506 (UnaryMutator.EmitCode): Use the right 1 value depending on
4507 whether we are dealing with int64/uint64, float or doubles.
4509 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
4510 constructors that I implemented last night.
4512 (Constructor.IsDefault): Fix to work properly for static
4515 * cs-parser.jay (CheckDef): report method signature errors.
4516 Update error number 103 to be 132.
4518 * decl.cs: New AdditionResult enumeration value: MethodExists.
4519 Although we do this check for methods later on in the semantic
4520 analysis, catching repeated default constructors is so easy that
4521 we catch these here.
4523 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
4526 (ParameterReference.EmitAssign, Emit): handle
4529 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
4530 (ArrayAccess.EmitStoreOpcode): ditto.
4532 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
4534 * expression.cs (MakeByteBlob): Complete all the missing types
4535 (uint, short, ushort, byte, sbyte)
4537 * class.cs: Only init instance field initializers on instance
4540 Rename `constructors' to instance_constructors.
4542 (TypeContainer.AddConstructor): Only add constructors to the list
4543 if it is not static.
4545 Make sure that we handle default_static_constructor independently
4546 everywhere where we handle instance_constructors
4548 2001-12-28 Miguel de Icaza <miguel@ximian.com>
4550 * class.cs: Do not lookup or create a base initializer for a
4553 (ConstructorInitializer.Resolve): use the proper type to lookup
4556 * cs-parser.jay: Report error 1585 (modifiers between type and name).
4558 * enum.cs, interface.cs: Remove CloseType, this is taken care by
4561 * decl.cs: CloseType is now an virtual method, the default
4562 implementation just closes this type.
4564 2001-12-28 Ravi Pratap <ravi@ximian.com>
4566 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
4567 to PreserveSig by default. Also emit HideBySig on such methods.
4569 Basically, set the defaults to standard values.
4571 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
4572 argument, if candidate is better, it can't be worse than the best !
4574 (Invocation): Re-write bits to differentiate between methods being
4575 applicable in their expanded form and their normal form - for params
4578 Get rid of use_standard everywhere as only standard conversions are allowed
4579 in overload resolution.
4581 More spec conformance.
4583 2001-12-27 Miguel de Icaza <miguel@ximian.com>
4585 * driver.cs: Add --timestamp, to see where the compiler spends
4588 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
4589 `this' in static code.
4591 (SimpleName.DoResolve): Implement in terms of a helper function
4592 that allows static-references to be passed upstream to
4595 (Expression.ResolveWithSimpleName): Resolve specially simple
4596 names when called by MemberAccess to implement the special
4599 (Expression.ImplicitReferenceConversion): Handle conversions from
4600 Null to reference types before others, as Null's type is
4603 * expression.cs (Invocation.EmitCall): Handle the special case of
4604 calling methods declared on a reference type from a ValueType
4605 (Base classes System.Object and System.Enum)
4607 (MemberAccess.Resolve): Only perform lookups on Enumerations if
4608 the left hand side is a TypeExpr, not on every enumeration.
4610 (Binary.Resolve): If types are reference types, then do a cast to
4611 object on operators != and == of both arguments.
4613 * typemanager.cs (FindMembers): Extract instance and static
4614 members if requested.
4616 * interface.cs (PopulateProperty): Use void_type instead of null
4617 as the return type for the setter method.
4619 (PopulateIndexer): ditto.
4621 2001-12-27 Ravi Pratap <ravi@ximian.com>
4623 * support.cs (ReflectionParameters): Fix minor bug where we
4624 were examining the wrong parameter for the ParamArray attribute.
4626 Cope with requests for the type of the parameter at position
4627 greater than the params parameter's. We now return the element
4628 type of the params array as that makes more sense.
4630 * expression.cs (Invocation.IsParamsMethodApplicable): Update
4631 accordingly as we no longer have to extract the element type
4634 (Invocation.OverloadResolve): Update.
4636 2001-12-27 Miguel de Icaza <miguel@ximian.com>
4638 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
4639 against IEnumerator, test whether the return value is a descendant
4640 of the IEnumerator interface.
4642 * class.cs (Indexer.Define): Use an auxiliary method to implement
4643 the other bits of the method definition. Begin support for
4644 explicit interface implementation.
4646 (Property.DefineMethod): Use TypeManager.void_type instead of null
4647 for an empty return value.
4649 2001-12-26 Miguel de Icaza <miguel@ximian.com>
4651 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
4652 dealing with a FieldExpr which is composed of a FieldBuilder, in
4653 the code path we did extract the constant, but we should have
4654 obtained the underlying value to be able to cast it (otherwise we
4655 end up in an infinite loop, this is what Ravi was running into).
4657 (ArrayCreation.UpdateIndices): Arrays might be empty.
4659 (MemberAccess.ResolveMemberAccess): Add support for section
4660 14.5.4.1 that deals with the special case of E.I when E is a type
4661 and something else, that I can be a reference to a static member.
4663 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
4664 handle a particular array type to create byte blobs, it is just
4665 something we dont generate byteblobs for.
4667 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
4670 * location.cs (Push): remove the key from the hashtable that we
4671 are about to add. This happens for empty files.
4673 * driver.cs: Dispose files after we have parsed them.
4675 (tokenize): new function that only runs the tokenizer on its
4676 input, for speed testing.
4678 2001-12-26 Ravi Pratap <ravi@ximian.com>
4680 * class.cs (Event.Define): Define the private field only if there
4681 are no accessors defined.
4683 * expression.cs (ResolveMemberAccess): If there is no associated
4684 field with the event, that means we have an event defined with its
4685 own accessors and we should flag error cs0070 since transforming
4686 ourselves into a field is not valid in that case.
4688 * ecore.cs (SimpleName.DoResolve): Same as above.
4690 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
4691 and charset to sane values.
4693 2001-12-25 Ravi Pratap <ravi@ximian.com>
4695 * assign.cs (DoResolve): Perform check on events only if they
4696 are being accessed outside the declaring type.
4698 * cs-parser.jay (event_declarations): Update rules to correctly
4699 set the type of the implicit parameter etc.
4701 (add_accessor, remove_accessor): Set current local parameters.
4703 * expression.cs (Binary): For delegate addition and subtraction,
4704 cast the return value from the method into the appropriate delegate
4707 2001-12-24 Ravi Pratap <ravi@ximian.com>
4709 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
4710 of these as the workaround is unnecessary.
4712 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
4713 delegate data - none of that is needed at all.
4715 Re-write bits to extract the instance expression and the delegate method
4718 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
4721 * attribute.cs (ApplyAttributes): New method to take care of common tasks
4722 of attaching attributes instead of duplicating code everywhere.
4724 * everywhere : Update code to do attribute emission using the above method.
4726 2001-12-23 Miguel de Icaza <miguel@ximian.com>
4728 * expression.cs (IsParamsMethodApplicable): if there are not
4729 parameters, return immediately.
4731 * ecore.cs: The 0 literal can be implicity converted to an enum
4734 (SimpleName.DoResolve): First lookup the type, then lookup the
4737 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
4738 want to get its address. If the InstanceExpression is not
4739 addressable, store the result in a temporary variable, then get
4742 * codegen.cs: Only display 219 errors on warning level or above.
4744 * expression.cs (ArrayAccess): Make it implement the
4745 IMemoryLocation interface.
4747 (Binary.DoResolve): handle the operator == (object a, object b)
4748 and operator != (object a, object b) without incurring into a
4749 BoxedCast (because 5 != o should never be performed).
4751 Handle binary enumerator operators.
4753 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
4754 value type, otherwise use Ldelem_ref.
4756 Use precomputed names;
4758 (AddressOf): Implement address of
4760 * cs-parser.jay (labeled_statement): Fix recursive block
4761 addition by reworking the production.
4763 * expression.cs (New.DoEmit): New has a special case:
4765 If we are dealing with a ValueType, we have a few
4766 situations to deal with:
4768 * The target of New is a ValueType variable, that is
4769 easy, we just pass this as the variable reference
4771 * The target of New is being passed as an argument,
4772 to a boxing operation or a function that takes a
4775 In this case, we need to create a temporary variable
4776 that is the argument of New.
4779 2001-12-23 Ravi Pratap <ravi@ximian.com>
4781 * rootcontext.cs (LookupType): Check that current_type is not null before
4782 going about looking at nested types.
4784 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
4785 not implement the IAssignMethod interface any more.
4787 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
4788 where we tranform them into FieldExprs if they are being resolved from within
4791 * ecore.cs (SimpleName.DoResolve): Do the same here.
4793 * assign.cs (DoResolve, Emit): Clean up code considerably.
4795 * ../errors/bug10.cs : Add.
4797 * ../errors/cs0070.cs : Add.
4799 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
4801 * assign.cs : Get rid of EventIsLocal everywhere.
4803 2001-12-23 Miguel de Icaza <miguel@ximian.com>
4805 * ecore.cs (ConvertIntLiteral): finished the implementation.
4807 * statement.cs (SwitchLabel): Convert the value we are using as a
4808 key before looking up the table.
4810 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4812 * codegen.cs (EmitTopBlock): Require a Location argument now.
4814 * cs-parser.jay (constructor_declarator): We need to setup
4815 current_local_parameters before we parse the
4816 opt_constructor_initializer, to allow the variables to be bound
4817 to the constructor arguments.
4819 * rootcontext.cs (LookupType): First lookup nested classes in our
4820 class and our parents before we go looking outside our class.
4822 * expression.cs (ConstantFold): Extract/debox the values at the
4825 * rootcontext.cs (EmitCode): Resolve the constants first before we
4826 resolve the types. This is not really needed, but it helps debugging.
4828 * statement.cs: report location.
4830 * cs-parser.jay: pass location to throw statement.
4832 * driver.cs: Small bug fix.
4834 * report.cs: Updated format to be 4-zero filled digits.
4836 2001-12-22 Ravi Pratap <ravi@ximian.com>
4838 * expression.cs (CheckIndices): Fix minor bug where the wrong
4839 variable was being referred to ;-)
4841 (DoEmit): Do not call EmitStaticInitializers when the
4842 underlying type is System.Object.
4844 2001-12-21 Ravi Pratap <ravi@ximian.com>
4846 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
4847 and do the usual workaround for SRE.
4849 * class.cs (MyEventBuilder.EventType): New member to get at the type
4850 of the event, quickly.
4852 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
4854 * assign.cs (Assign.DoResolve): Handle the case when the target
4855 is an EventExpr and perform the necessary checks.
4857 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
4860 (SimpleName.MemberStaticCheck): Include check for EventExpr.
4862 (EventExpr): Set the type in the constructor itself since we
4863 are meant to be born fully resolved.
4865 (EventExpr.Define): Revert code I wrote earlier.
4867 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
4868 instance expression is null. The instance expression is a This in that case
4869 or a null, depending on whether it is a static method or not.
4871 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
4872 refers to more than one method.
4874 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
4875 and accordingly flag errors.
4877 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4879 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
4881 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4883 * location.cs (ToString): Provide useful rutine.
4885 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4887 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
4888 objects, return the actual integral boxed.
4890 * statement.cs (SwitchLabel): define an ILLabel for each
4893 (Switch.CheckSwitch): If the value is a Literal, extract
4894 the underlying literal.
4896 Also in the unused hashtable we had, add the SwitchLabel so we can
4897 quickly look this value up.
4899 * constant.cs: Implement a bunch of new constants. Rewrite
4900 Literal based on this. Made changes everywhere to adapt to this.
4902 * expression.cs (Expression.MakeByteBlob): Optimize routine by
4903 dereferencing array only once, and also copes with enumrations.
4905 bytes are two bytes wide, not one.
4907 (Cast): Perform constant conversions.
4909 * ecore.cs (TryImplicitIntConversion): Return literals instead of
4910 wrappers to the literals here.
4912 * expression.cs (DoNumericPromotions): long literals can converted
4913 to ulong implicity (this is taken care of elsewhere, but I was
4916 * ecore.cs (Expression.Literalize): Make the return type Literal,
4917 to improve type checking.
4919 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
4921 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4923 * literal.cs: Revert code from ravi that checked the bounds. The
4924 bounds are sane by the definition of the type itself.
4926 * typemanager.cs: Fix implementation of ImplementsInterface. We
4927 need to actually look up in our parent hierarchy for interfaces
4930 * const.cs: Use the underlying type for enumerations
4932 * delegate.cs: Compute the basename for the delegate creation,
4933 that should fix the delegate test case, and restore the correct
4934 Type Lookup semantics in rootcontext
4936 * rootcontext.cs: Revert Ravi's last patch. The correct way of
4937 referencing a nested type with the Reflection API is using the "+"
4940 * cs-parser.jay: Do not require EOF token at the end.
4942 2001-12-20 Ravi Pratap <ravi@ximian.com>
4944 * rootcontext.cs (LookupType): Concatenate type names with
4945 a '.' instead of a '+' The test suite passes again.
4947 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
4948 field of the enumeration.
4950 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
4951 the case when the member is an EventExpr.
4953 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
4954 static has an associated instance expression.
4956 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
4958 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
4960 * class.cs (Event.Define): Register event and perform appropriate checks
4963 We define the Add and Remove methods even if the use provides none because
4964 in that case, we provide default implementations ourselves.
4966 Define a private field of the type of the event. This is done by the CSC compiler
4967 and we should be doing it too ;-)
4969 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
4970 More methods we use in code we generate.
4972 (multicast_delegate_type, delegate_type): Two separate types since the distinction
4975 (InitCoreTypes): Update accordingly for the above.
4977 * class.cs (Event.Emit): Generate code for default accessors that we provide
4979 (EmitDefaultMethod): Do the job in the above.
4981 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
4984 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4986 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
4987 builders even if we were missing one.
4989 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
4990 pass the Basename as our class name instead of the Name. The
4991 basename will be correctly composed for us.
4993 * parameter.cs (Paramters): Now takes a Location argument.
4995 * decl.cs (DeclSpace.LookupType): Removed convenience function and
4996 make all the code call directly LookupType in RootContext and take
4997 this chance to pass the Location information everywhere.
4999 * Everywhere: pass Location information.
5001 2001-12-19 Miguel de Icaza <miguel@ximian.com>
5003 * class.cs (Constructor.Define): Updated way of detecting the
5004 length of the parameters.
5006 (TypeContainer.DefineType): Use basename as the type name for
5009 (TypeContainer.Define): Do not recursively define types here, as
5010 definition is taken care in order by the RootContext.
5012 * tree.cs: Keep track of namespaces in a per-file basis.
5014 * parameter.cs (Parameter.ComputeSignature): Update to use
5017 (Parameters.GetSignature): ditto.
5019 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
5020 instead of a TypeContainer.
5022 (Interface.SemanticAnalysis): Use `this' instead of our parent to
5023 resolve names. Because we need to be resolve in our context, not
5026 * driver.cs: Implement response files.
5028 * class.cs (TypeContainer.DefineType): If we are defined, do not
5031 (Event.Emit): Emit the code for add/remove handlers.
5032 (Event.Define): Save the MethodBuilders for add/remove.
5034 * typemanager.cs: Use pair here too.
5036 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
5037 DictionaryEntry requires the first argument to be non-null.
5039 (enum_declaration): Compute full name for registering the
5042 (delegate_declaration): Instead of using
5043 formal_parameter_list, use opt_formal_parameter_list as the list
5046 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
5047 (EventParsing): New property that controls whether `add' and
5048 `remove' are returned as tokens or identifiers (for events);
5050 2001-12-19 Ravi Pratap <ravi@ximian.com>
5052 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
5053 use MyEventBuilder only and let it wrap the real builder for us.
5055 (MyEventBuilder): Revamp constructor etc.
5057 Implement all operations that we perform on EventBuilder in precisely the same
5060 (FindMembers): Update to use the EventBuilder member.
5062 (Event.Emit): Update accordingly.
5064 2001-12-18 Ravi Pratap <ravi@ximian.com>
5066 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
5067 by calling the appropriate methods.
5069 (GetCustomAttributes): Make stubs as they cannot possibly do anything
5072 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
5074 2001-12-17 Ravi Pratap <ravi@ximian.com>
5076 * delegate.cs (Delegate.Populate): Check that the return type
5077 and various parameters types are indeed accessible.
5079 * class.cs (Constructor.Define): Same here.
5081 (Field.Define): Ditto.
5083 (Event.Define): Ditto.
5085 (Operator.Define): Check that the underlying Method defined itself
5086 correctly - so it's MethodBuilder should not be null.
5088 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
5089 expression happens to be null.
5091 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
5092 members but as of now we don't seem to be able to do anything really useful with it.
5094 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
5095 not the EventBuilder.
5097 2001-12-18 Miguel de Icaza <miguel@ximian.com>
5099 * cs-tokenizer.cs: Add support for defines.
5100 Add support for #if, #elif, #else, #endif
5102 (eval_var): evaluates a variable.
5103 (eval): stubbed for evaluating functions.
5105 * cs-parser.jay: Pass the defines information
5107 * driver.cs: Add --define command line option.
5109 * decl.cs: Move MemberCore here.
5111 Make it the base class for DeclSpace. This allows us to catch and
5112 report 108 and 109 for everything now.
5114 * class.cs (TypeContainer.Define): Extract all the members
5115 before populating and emit the warning 108 (new keyword required
5116 to override) instead of having each member implement this.
5118 (MemberCore.Define): New abstract method, we will be using this in
5119 the warning reporting engine in Populate.
5121 (Operator.Define): Adjust to new MemberCore protocol.
5123 * const.cs (Const): This does not derive from Expression, it is a
5124 temporary object we use to create fields, it is a MemberCore.
5126 * class.cs (Method.Define): Allow the entry point to be in a
5129 * driver.cs: Rewrite the argument handler to clean it up a bit.
5131 * rootcontext.cs: Made it just an auxiliary namespace feature by
5132 making everything static.
5134 * driver.cs: Adapt code to use RootContext type name instead of
5137 * delegate.cs: Remove RootContext argument.
5139 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
5142 * class.cs (Event.Define): The lookup can fail.
5144 * cs-tokenizer.cs: Begin implementation of pre-procesor.
5146 * expression.cs: Resolve the this instance before invoking the code.
5148 2001-12-17 Miguel de Icaza <miguel@ximian.com>
5150 * cs-parser.jay: Add a production in element_access that allows
5151 the thing to become a "type" reference. This way we can parse
5152 things like "(string [])" as a type.
5154 Note that this still does not handle the more complex rules of
5158 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
5160 * ecore.cs: (CopyNewMethods): new utility function used to
5161 assemble the list of methods from running FindMembers.
5163 (MemberLookup): Rework FindMembers so that
5165 2001-12-16 Miguel de Icaza <miguel@ximian.com>
5167 * class.cs (TypeContainer): Remove Delegates who fail to be
5170 * delegate.cs (Populate): Verify that we dont get null return
5171 values. TODO: Check for AsAccessible.
5173 * cs-parser.jay: Use basename to emit error 574 (destructor should
5174 have the same name as container class), not the full name.
5176 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
5177 possible representation.
5179 Also implements integer type suffixes U and L.
5181 2001-12-15 Miguel de Icaza <miguel@ximian.com>
5183 * expression.cs (ArrayCreation.DoResolve): We need to do the
5184 argument resolution *always*.
5186 * decl.cs: Make this hold the namespace. Hold the root context as
5188 (LookupType): Move here.
5190 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
5192 * location.cs (Row, Name): Fixed the code, it was always returning
5193 references to the first file.
5195 * interface.cs: Register properties defined through interfaces.
5197 * driver.cs: Add support for globbing on the command line
5199 * class.cs (Field): Make it derive from MemberCore as well.
5202 2001-12-15 Ravi Pratap <ravi@ximian.com>
5204 * class.cs (Event::Define): Check that the type of the event is a delegate
5205 type else flag error #66.
5207 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
5210 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
5211 values of EntryPoint, CharSet etc etc.
5213 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
5215 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
5216 be null and we should ignore this. I am not sure if this is really clean. Apparently,
5217 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
5218 which needs this to do its work.
5220 * ../errors/cs0066.cs : Add.
5222 2001-12-14 Miguel de Icaza <miguel@ximian.com>
5224 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
5227 * class.cs: (MethodSignature.MethodSignature): Removed hack that
5228 clears out the parameters field.
5229 (MemberSignatureCompare): Cleanup
5231 (MemberCore): New base class used to share code between MethodCore
5234 (RegisterRequiredImplementations) BindingFlags.Public requires
5235 either BindingFlags.Instace or Static. Use instance here.
5237 (Property): Refactored code to cope better with the full spec.
5239 * parameter.cs (GetParameterInfo): Return an empty array instead
5242 * class.cs (Property): Abstract or extern properties have no bodies.
5244 * parameter.cs (GetParameterInfo): return a zero-sized array.
5246 * class.cs (TypeContainer.MethodModifiersValid): Move all the
5247 method modifier validation to the typecontainer so we can reuse
5250 (MethodCore.ParameterTypes): return an empty sized array of types.
5252 (Property.Define): Test property modifier validity.
5254 Add tests for sealed/override too.
5256 (Method.Emit): abstract or extern methods have no bodies.
5258 2001-12-14 Ravi Pratap <ravi@ximian.com>
5260 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
5263 (Method::Define, ::Emit): Modify accordingly.
5265 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
5267 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
5269 * makefile: Pass in /unsafe.
5271 2001-12-13 Miguel de Icaza <miguel@ximian.com>
5273 * class.cs (MakeKey): Kill routine.
5275 * class.cs (TypeContainer.Define): Correctly define explicit
5276 method implementations (they require the full interface name plus
5279 * typemanager.cs: Deply the PtrHashtable here and stop using the
5280 lame keys. Things work so much better.
5282 This of course broke everyone who depended on `RegisterMethod' to
5283 do the `test for existance' test. This has to be done elsewhere.
5285 * support.cs (PtrHashtable): A hashtable that avoid comparing with
5286 the object stupid Equals method (because, that like fails all over
5287 the place). We still do not use it.
5289 * class.cs (TypeContainer.SetRequiredInterface,
5290 TypeContainer.RequireMethods): Killed these two routines and moved
5291 all the functionality to RegisterRequiredImplementations.
5293 (TypeContainer.RegisterRequiredImplementations): This routine now
5294 registers all the implementations required in an array for the
5295 interfaces and abstract methods. We use an array of structures
5296 which can be computed ahead of time to reduce memory usage and we
5297 also assume that lookups are cheap as most classes will not
5298 implement too many interfaces.
5300 We also avoid creating too many MethodSignatures.
5302 (TypeContainer.IsInterfaceMethod): Update and optionally does not
5303 clear the "pending" bit if we find that there are problems with
5306 (TypeContainer.VerifyPendingMethods): Update to report errors of
5307 methods that look like implementations but are not.
5309 (TypeContainer.Define): Add support for explicit interface method
5312 2001-12-12 Miguel de Icaza <miguel@ximian.com>
5314 * typemanager.cs: Keep track of the parameters here instead of
5315 being a feature of the TypeContainer.
5317 * class.cs: Drop the registration of parameters here, as
5318 InterfaceMethods are also interface declarations.
5320 * delegate.cs: Register methods with the TypeManager not only with
5321 the TypeContainer. This code was buggy.
5323 * interface.cs: Full registation here.
5325 2001-12-11 Miguel de Icaza <miguel@ximian.com>
5327 * expression.cs: Remove reducer for binary expressions, it can not
5330 * const.cs: Put here the code that used to go into constant.cs
5332 * constant.cs: Put here the code for constants, this is a new base
5335 * literal.cs: Make Literal derive from Constant.
5337 2001-12-09 Miguel de Icaza <miguel@ximian.com>
5339 * statement.cs (Return.Emit): Report error 157 if the user
5340 attempts to return from a finally block.
5342 (Return.Emit): Instead of emitting a return, jump to the end of
5345 * codegen.cs (EmitContext): ReturnValue, ReturnLabel: new
5346 LocalBuilder to store the result of the function. ReturnLabel is
5347 the target where we jump.
5350 2001-12-09 Radek Doulik <rodo@ximian.com>
5352 * cs-parser.jay: remember alias in current namespace
5354 * ecore.cs (SimpleName::DoResolve): use aliases for types or
5357 * class.cs (LookupAlias): lookup alias in my_namespace
5359 * namespace.cs (UsingAlias): add alias, namespace_or_type pair to
5361 (LookupAlias): lookup alias in this and if needed in parent
5364 2001-12-08 Miguel de Icaza <miguel@ximian.com>
5368 * rootcontext.cs: (ModuleBuilder) Made static, first step into
5369 making things static. I need this to avoid passing the
5370 TypeContainer when calling ParameterType.
5372 * support.cs (InternalParameters.ParameterType): Remove ugly hack
5373 that did string manipulation to compute the type and then call
5374 GetType. Use Parameter.ParameterType instead.
5376 * cs-tokenizer.cs: Consume the suffix for floating values.
5378 * expression.cs (ParameterReference): figure out whether this is a
5379 reference parameter or not. Kill an extra variable by computing
5380 the arg_idx during emission.
5382 * parameter.cs (Parameters.GetParameterInfo): New overloaded
5383 function that returns whether a parameter is an out/ref value or not.
5385 (Parameter.ParameterType): The type of the parameter (base,
5386 without ref/out applied).
5388 (Parameter.Resolve): Perform resolution here.
5389 (Parameter.ExternalType): The full type (with ref/out applied).
5391 * statement.cs (Using.Emit, Using.EmitExpression): Implement
5392 support for expressions on the using statement.
5394 2001-12-07 Miguel de Icaza <miguel@ximian.com>
5396 * statement.cs (Using.EmitLocalVariableDecls): Split the
5397 localvariable handling of the using statement.
5399 (Block.EmitMeta): Keep track of variable count across blocks. We
5400 were reusing slots on separate branches of blocks.
5402 (Try.Emit): Emit the general code block, we were not emitting it.
5404 Check the type of the declaration to be an IDisposable or
5405 something that can be implicity converted to it.
5407 Emit conversions if required.
5409 * ecore.cs (EmptyExpression): New utility class.
5410 (Expression.ImplicitConversionExists): New utility function.
5412 2001-12-06 Miguel de Icaza <miguel@ximian.com>
5414 * statement.cs (Using): Implement.
5416 * expression.cs (LocalVariableReference): Support read only variables.
5418 * statement.cs: Remove the explicit emit for the Leave opcode.
5419 (VariableInfo): Add a readonly field.
5421 2001-12-05 Miguel de Icaza <miguel@ximian.com>
5423 * ecore.cs (ConvCast): new class used to encapsulate the various
5424 explicit integer conversions that works in both checked and
5427 (Expression.ConvertNumericExplicit): Use new ConvCast class to
5428 properly generate the overflow opcodes.
5430 2001-12-04 Miguel de Icaza <miguel@ximian.com>
5432 * statement.cs: The correct type for the EmptyExpression is the
5433 element_type, not the variable type. Ravi pointed this out.
5435 2001-12-04 Ravi Pratap <ravi@ximian.com>
5437 * class.cs (Method::Define): Handle PInvoke methods specially
5438 by using DefinePInvokeMethod instead of the usual one.
5440 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
5441 above to do the task of extracting information and defining the method.
5443 2001-12-04 Ravi Pratap <ravi@ximian.com>
5445 * expression.cs (ArrayCreation::EmitStaticInitializers): Get rid
5446 of the condition for string type.
5448 (Emit): Move that here.
5450 (ArrayCreation::CheckIndices): Keep string literals in their expression
5453 (EmitDynamicInitializers): Handle strings appropriately.
5455 2001-12-04 Miguel de Icaza <miguel@ximian.com>

5458 single pointer to the current Switch statement.
5460 * statement.cs (GotoDefault, Switch): Adjust to cleaned up
5463 2001-12-03 Miguel de Icaza <miguel@ximian.com>
5467 * statement.cs (GotoDefault), cs-parser.jay: Implement `goto
5470 (Foreach.Emit): Foreach on arrays was not setting
5471 up the loop variables (for break/continue).
5473 (GotoCase): Semi-implented.
5475 2001-12-03 Ravi Pratap <ravi@ximian.com>
5477 * attribute.cs (CheckAttribute): Handle system attributes by using
5478 Attribute.GetAttributes to examine information we need.

5524 * expression.cs (Probe, Is, As): Split Probe in two classes Is and
5525 As that share bits of the implementation. Is returns a boolean,
5526 while As returns the Type that is being probed.
5528 2001-12-01 Ravi Pratap <ravi@ximian.com>
5530 * enum.cs (LookupEnumValue): Re-write various bits, return an object value
5531 instead of a Literal - much easier.
5533 (EnumInTransit): Remove - utterly useless :-)
5535 (Populate): Re-write bits - remove duplicate code etc. The code is much neater now.
5537 * expression.cs (MemberLookup): Cope with user-defined enums when they are in transit.
5539 * enum.cs (LookupEnumValue): Auto-compute next values by going down the dependency
5540 chain when we have no associated expression.

5601 in the case when we are looking for MemberTypes.Field
5603 * expression.cs (MemberAccess::DoResolve): Check that in the

5654 * cs-parser.jay: Remove bogus fixme.
5656 * statement.cs (Switch, SwitchSection, SwithLabel): Started work

5661 * typemanager.cs (IsDelegateType, IsEnumType): Fix logic to determine
5664 * expression.cs (ArrayCreation::CheckIndices): Get rid of the require_constant
5665 parameter. Apparently, any expression is allowed.

5669 (CheckIndices): Fix some tricky bugs thanks to recursion.
5671 * delegate.cs (NewDelegate::DoResolve): Re-write large portions as
5672 I was being completely brain-dead.
5674 (VerifyMethod, VerifyApplicability, VerifyDelegate): Make static
5675 and re-write acordingly.
5677 (DelegateInvocation): Re-write accordingly.
5679 * expression.cs (ArrayCreation::Emit): Handle string initialization separately.
5681 (MakeByteBlob): Handle types more correctly.
5683 * expression.cs (ArrayCreation:Emit): Write preliminary code to do
5684 initialization from expressions but it is incomplete because I am a complete
5687 2001-11-22 Miguel de Icaza <miguel@ximian.com>
5689 * statement.cs (If.Emit): Fix a bug that generated incorrect code
5690 on If. Basically, we have to return `true' (ie, we do return to
5691 our caller) only if both branches of the if return.
5693 * expression.cs (Binary.Emit): LogicalOr and LogicalAnd are
5694 short-circuit operators, handle them as short circuit operators.

5697 (Cast.Cast): Take an expression as the target type.
5699 * cs-parser.jay (cast_expression): Remove old hack that only
5700 allowed a limited set of types to be handled. Now we take a
5701 unary_expression and we resolve to a type during semantic
5704 Use the grammar productions from Rhys to handle casts (this is
5705 not complete like Rhys syntax yet, we fail to handle that corner
5706 case that C# has regarding (-x), but we will get there.
5708 2001-11-22 Ravi Pratap <ravi@ximian.com>
5710 * class.cs (EmitFieldInitializer): Take care of the case when we have a
5711 field which is an array type.

5725 (MemberAccess::DoResolve): Fix the code which handles Enum literals to set
5726 the correct type etc.
5728 (ConvertExplicit): Handle Enum types by examining the underlying type.

5743 BindingFlags.Instance as well
5745 * ecore.cs (Expression.TryImplicitIntConversion): Wrap the result
5746 implicit int literal conversion in an empty cast so that we
5747 propagate the right type upstream.
5749 (UnboxCast): new class used to unbox value types.
5750 (Expression.ConvertExplicit): Add explicit type conversions done
5753 (Expression.ImplicitNumericConversion): Oops, forgot to test for
5754 the target type before applying the implicit LongLiterals to ULong
5757 2001-11-21 Miguel de Icaza <miguel@ximian.com>
5759 * cs-parser.jay (for_statement): Reworked the way For works: now
5760 we declare manually any variables that are introduced in
5761 for_initializer to solve the problem of having out-of-band code
5762 emition (that is what got for broken).
5764 (declaration_statement): Perform the actual variable declaration
5765 that used to be done in local_variable_declaration here.
5767 (local_variable_declaration): Do not declare anything, just pass
5768 the information on a DictionaryEntry
5770 2001-11-20 Ravi Pratap <ravi@ximian.com>
5772 * expression.cs (ArrayCreation::CheckIndices): The story continues :-) Complete

5835 we can use this elsewhere.
5837 * statement.cs: Finish implementation of foreach for single
5840 * cs-parser.jay: Use an out-of-band stack to pass information
5841 around, I wonder why I need this.
5843 foreach_block: Make the new foreach_block the current_block.
5845 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
5846 function used to return a static Parameters structure. Used for

5856 2001-11-15 Ravi Pratap <ravi@ximian.com>
5858 * support.cs (ReflectionParameters): Fix logic to determine
5859 whether the last parameter is a params one. Test 9 passes again.
5861 * delegate.cs (Populate): Register the builders we define with
5862 RegisterParameterForBuilder. Test 19 passes again.
5864 * cs-parser.jay (property_declaration): Reference $6 instead
5865 of $$ to get at the location.
5867 (indexer_declaration): Similar stuff.
5871 * class.cs (Property): Register parameters for the Get and Set methods
5872 if they exist. Test 23 passes again.

5879 IndexOutOfRangeException.
5881 * class.cs (Property::Define): Register property using TypeManager.RegisterProperty
5882 Test 33 now passes again.
5884 2001-11-15 Miguel de Icaza <miguel@ximian.com>
5886 * cs-parser.jay: Kill horrendous hack ($??? = lexer.Location) that
5887 broke a bunch of things. Will have to come up with a better way

5892 2001-11-09 Miguel de Icaza <miguel@ximian.com>

5913 way we can report the error correctly for missing return values.
5915 * class.cs (Method.Emit): Clean up.
5917 * expression.cs (Argument.Resolve): Take another argument: the
5918 location where this argument is used. Notice that this is not
5919 part of the "Argument" class as to reduce the size of the
5920 structure (we know the approximate location anyways).
5922 Test if the argument is a variable-reference, if not, then
5923 complain with a 206.
5925 (Argument.Emit): Emit addresses of variables.
5927 (Argument.FullDesc): Simplify.
5929 (Invocation.DoResolve): Update for Argument.Resolve.
5931 (ElementAccess.DoResolve): ditto.

5956 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
5957 enumerations that are used in heavily used structures derive from
5958 byte in a laughable and pathetic attempt to reduce memory usage.
5959 This is the kind of pre-optimzations that you should not do at
5960 home without adult supervision.
5962 * expression.cs (UnaryMutator): New class, used to handle ++ and
5963 -- separatedly from the other unary operators. Cleans up the
5964 code, and kills the ExpressionStatement dependency in Unary.
5966 (Unary): Removed `method' and `Arguments' from this class, making
5967 it smaller, and moving it all to SimpleCall, so I can reuse this
5968 code in other locations and avoid creating a lot of transient data
5969 strucutres when not required.
5971 * cs-parser.jay: Adjust for new changes.
5973 2001-11-11 Miguel de Icaza <miguel@ximian.com>
5975 * enum.cs (Enum.Populate): If there is a failure during

6044 of a fieldinfo using the above, when dealing with a FieldBuilder.

6130 Emit method everywhere.
6132 * enum.cs (Enum): Revamp to use the same definition semantics as delegates so
6133 we have a DefineEnum, CloseEnum etc. The previous way of doing things was not right
6134 as we had no way of defining nested enums !
6136 * rootcontext.cs : Adjust code accordingly.
6138 * typemanager.cs (AddEnumType): To keep track of enum types separately.
6140 2001-11-07 Ravi Pratap <ravi@ximian.com>

6211 assinging, probe for the IStackStore/IAssignMethod interfaces.
6213 * typemanager.cs: Load InitializeArray definition.

6350 (ReflectionParameters, InternalParameters): Update accordingly.
6352 * expression.cs (Argument::GetParameterModifier): Same here.
6354 * support.cs (InternalParameters::ParameterType): Find a better way of determining
6355 if we are a ref/out parameter. Actually, the type shouldn't be holding the '&'
6356 symbol in it at all so maybe this is only for now.
6358 2001-10-30 Ravi Pratap <ravi@ximian.com>
6360 * support.cs (InternalParameters): Constructor now takes an extra argument
6361 which is the actual Parameters class.

6726 and accordingly handle it.
6728 * delegate.cs (Populate): Take TypeContainer argument.

6811 methods on value types. We need to pass the address to structure
6812 methods rather than the object itself. (The equivalent code to
6813 emit "this" for structures leaves the entire structure on the
6814 stack instead of a pointer to it).
6816 (ParameterReference::DoResolve): Compute the real index for the
6817 argument based on whether the method takes or not a `this' pointer
6818 (ie, the method is static).

6859 to TypeContainer mapping to see if a type is user-defined.
6861 * class.cs (TypeContainer::CloseType): Implement.

6891 expected return type.
6893 Validate use of return statement.
6895 * codegen.cs (EmitContext): Pass the expected return type here.
6897 * class.cs (Method, Constructor, Property): Pass expected return
6898 type to EmitContext.

6981 * class.cs: Catch static methods having the flags override,
6982 virtual or abstract.
6984 * expression.cs (UserCast): This user cast was not really doing
6985 what it was supposed to do. Which is to be born in fully resolved
6986 state. Parts of the resolution were being performed at Emit time!
6990 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6992 * expression.cs: Implicity convert the result from UserCast.

7018 UserDefinedConversion.

7060 instead of inside a tight loop.
7062 (::RequireMethods): Accept an object as the data to set into the
7063 hashtable so we can report interface vs abstract method mismatch.
7065 2001-10-03 Miguel de Icaza <miguel@ximian.com>
7067 * report.cs: Make all of it static.
7069 * rootcontext.cs: Drop object_type and value_type computations, as
7070 we have those in the TypeManager anyways.
7072 Drop report instance variable too, now it is a global.

7076 Add --probe option to debug the error reporting system with a test

7110 (::FindMostEncompassingType): Implement.
7111 (::StandardConversionExists): Implement.
7113 (UserImplicitCast): Re-vamp. We now need info about most specific
7114 source and target types so that we can do the necessary conversions.
7116 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
7117 mathematical union with no duplicates.
7119 2001-10-03 Miguel de Icaza <miguel@ximian.com>
7121 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
7122 in order from base classes to child classes, so that we can in
7123 child classes look up in our parent for method names and
7124 attributes (required for handling abstract, virtual, new, override
7125 constructs: we need to instrospect our base class, and if we dont
7126 populate the classes in order, the introspection might be
7127 incorrect. For example, a method could query its parent before
7128 the parent has any methods and would determine that the parent has
7129 no abstract methods (while it could have had them)).
7131 (RootContext::CreateType): Record the order in which we define the
7134 2001-10-02 Miguel de Icaza <miguel@ximian.com>
7136 * class.cs (TypeContainer::Populate): Also method definitions can
7137 fail now, keep track of this.

7152 not marked abstract or extern).
7154 * expression.cs (TypeOf::Emit): Implement.
7156 * typemanager.cs: runtime_handle_type, new global type.
7158 * class.cs (Property::Emit): Generate code for properties.
7160 2001-10-02 Ravi Pratap <ravi@ximian.com>
7162 * expression.cs (Unary::ResolveOperator): Find operators on base type
7163 too - we now conform exactly to the spec.
7165 (Binary::ResolveOperator): Same here.
7167 * class.cs (Operator::Define): Fix minor quirk in the tests.
7169 * ../errors/cs0215.cs : Added.
7171 * ../errors/cs0556.cs : Added.
7173 * ../errors/cs0555.cs : Added.
7175 2001-10-01 Miguel de Icaza <miguel@ximian.com>
7177 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
7178 single integer which is really efficient
7180 2001-10-01 Ravi Pratap <ravi@ximian.com>
7182 * expression.cs (Expression::ImplicitUserConversion): Use location
7183 even in the case when we are examining True operators.
7185 * class.cs (Operator::Define): Perform extensive checks to conform
7186 with the rules for operator overloading in the spec.
7188 * expression.cs (Expression::ImplicitReferenceConversion): Implement
7189 some of the other conversions mentioned in the spec.
7191 * typemanager.cs (array_type): New static member for the System.Array built-in
7194 (cloneable_interface): For System.ICloneable interface.
7196 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
7197 we start resolving the tree and populating types.
7199 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
7201 2001-10-01 Miguel de Icaza <miguel@ximian.com>
7203 * expression.cs (Expression::ExprClassFromMemberInfo,
7204 Expression::Literalize): Create literal expressions from
7205 FieldInfos which are literals.
7207 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
7208 type casts, because they were wrong. The test suite in tests
7211 (ImplicitNumericConversion): ushort to ulong requires a widening
7214 Int32 constant to long requires widening cast as well.
7216 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
7217 for integers because the type on the stack is not i4.
7219 2001-09-30 Miguel de Icaza <miguel@ximian.com>
7221 * expression.cs (report118): require location argument.
7223 * parameter.cs: Do not dereference potential null value.
7225 * class.cs: Catch methods that lack the `new' keyword when
7226 overriding a name. Report warnings when `new' is used without
7227 anything being there to override.
7229 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
7231 * class.cs: Only add constructor to hashtable if it is non-null
7232 (as now constructors can fail on define).
7234 (TypeManager, Class, Struct): Take location arguments.
7236 Catch field instance initialization in structs as errors.
7238 accepting_filter: a new filter for FindMembers that is static so
7239 that we dont create an instance per invocation.
7241 (Constructor::Define): Catch errors where a struct constructor is
7244 * cs-parser.jay: Pass location information for various new
7247 * delegate.cs (Delegate): take a location argument.
7249 * driver.cs: Do not call EmitCode if there were problesm in the
7250 Definition of the types, as many Builders wont be there.
7252 * decl.cs (Decl::Decl): Require a location argument.
7254 * cs-tokenizer.cs: Handle properly hex constants that can not fit
7255 into integers, and find the most appropiate integer for it.
7257 * literal.cs: Implement ULongLiteral.
7259 * rootcontext.cs: Provide better information about the location of
7260 failure when CreateType fails.
7262 2001-09-29 Miguel de Icaza <miguel@ximian.com>
7264 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
7267 * expression.cs (Binary::CheckShiftArguments): Add missing type
7269 (Binary::ResolveOperator): Add type to the logical and and logical
7270 or, Bitwise And/Or and Exclusive Or code paths, it was missing
7273 (Binary::DoNumericPromotions): In the case where either argument
7274 is ulong (and most signed types combined with ulong cause an
7275 error) perform implicit integer constant conversions as well.
7277 2001-09-28 Miguel de Icaza <miguel@ximian.com>
7279 * expression.cs (UserImplicitCast): Method should always be
7281 (Invocation::BetterConversion): Simplified test for IntLiteral.
7283 (Expression::ImplicitNumericConversion): Split this routine out.
7284 Put the code that performs implicit constant integer conversions
7287 (Expression::Resolve): Become a wrapper around DoResolve so we can
7288 check eclass and type being set after resolve.
7290 (Invocation::Badness): Remove this dead function
7292 (Binary::ResolveOperator): Do not compute the expensive argumnets
7293 unless we have a union for it.
7295 (Probe::Emit): Is needs to do an isinst and then
7296 compare against null.
7298 (::CanConvert): Added Location argument. If the Location argument
7299 is null (Location.Null), then we do not report errors. This is
7300 used by the `probe' mechanism of the Explicit conversion. We do
7301 not want to generate an error for something that the user
7302 explicitly requested to be casted. But the pipeline for an
7303 explicit cast first tests for potential implicit casts.
7305 So for now, if the Location is null, it means `Probe only' to
7306 avoid adding another argument. Might have to revise this
7309 (ClassCast): New class used to type cast objects into arbitrary
7310 classes (used in Explicit Reference Conversions).
7312 Implement `as' as well.
7314 Reverted all the patches from Ravi below: they were broken:
7316 * The use of `level' as a mechanism to stop recursive
7317 invocations is wrong. That was there just to catch the
7318 bug with a strack trace but not as a way of addressing
7321 To fix the problem we have to *understand* what is going
7322 on and the interactions and come up with a plan, not
7323 just get things going.
7325 * The use of the type conversion cache that I proposed
7326 last night had an open topic: How does this work across
7327 protection domains. A user defined conversion might not
7328 be public in the location where we are applying the
7329 conversion, a different conversion might be selected
7330 (ie, private A->B (better) but public B->A (worse),
7331 inside A, A->B applies, but outside it, B->A will
7334 * On top of that (ie, even if the above is solved),
7335 conversions in a cache need to be abstract. Ie, `To
7336 convert from an Int to a Short use an OpcodeCast', not
7337 `To convert from an Int to a Short use the OpcodeCast on
7338 the variable 5' (which is what this patch was doing).
7340 2001-09-28 Ravi Pratap <ravi@ximian.com>
7342 * expression.cs (Invocation::ConversionExists): Re-write to use
7343 the conversion cache
7345 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
7346 cache all conversions done, not just user-defined ones.
7348 (Invocation::BetterConversion): The real culprit. Use ConversionExists
7349 to determine if a conversion exists instead of acutually trying to
7350 perform the conversion. It's faster too.
7352 (Expression::ConvertExplicit): Modify to use ConversionExists to check
7353 and only then attempt the implicit conversion.
7355 2001-09-28 Ravi Pratap <ravi@ximian.com>
7357 * expression.cs (ConvertImplicit): Use a cache for conversions
7358 already found. Check level of recursion and bail out if necessary.
7360 2001-09-28 Miguel de Icaza <miguel@ximian.com>
7362 * typemanager.cs (string_concat_string_string, string_concat_object_object):
7363 Export standard methods that we expect for string operations.
7365 * statement.cs (Block::UsageWarning): Track usage of variables and
7366 report the errors for not used variables.
7368 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
7371 2001-09-27 Miguel de Icaza <miguel@ximian.com>
7373 * codegen.cs: remove unnneded code
7375 * expression.cs: Removed BuiltinTypeAccess class
7377 Fix the order in which implicit conversions are
7380 The previous fixed dropped support for boxed conversions (adding a
7381 test to the test suite now)
7383 (UserImplicitCast::CanConvert): Remove test for source being null,
7384 that code is broken. We should not feed a null to begin with, if
7385 we do, then we should track the bug where the problem originates
7386 and not try to cover it up here.
7388 Return a resolved expression of type UserImplicitCast on success
7389 rather than true/false. Ravi: this is what I was talking about,
7390 the pattern is to use a static method as a "constructor" for
7393 Also, do not create arguments until the very last minute,
7394 otherwise we always create the arguments even for lookups that
7395 will never be performed.
7397 (UserImplicitCast::Resolve): Eliminate, objects of type
7398 UserImplicitCast are born in a fully resolved state.
7400 * typemanager.cs (InitCoreTypes): Init also value_type
7403 * expression.cs (Cast::Resolve): First resolve the child expression.
7405 (LValue): Add new method AddressOf to be used by
7408 Change the argument of Store to take an EmitContext instead of an
7409 ILGenerator, because things like FieldExpr need to be able to call
7410 their children expression to generate the instance code.
7412 (Expression::Error, Expression::Warning): Sugar functions for
7415 (Expression::MemberLookup): Accept a TypeContainer instead of a
7416 Report as the first argument.
7418 (Expression::ResolvePrimary): Killed. I still want to improve
7419 this as currently the code is just not right.
7421 (Expression::ResolveMemberAccess): Simplify, but it is still
7424 (Unary::Resolve): Catch errors in AddressOf operators.
7426 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
7427 index to a byte for the short-version, or the compiler will choose
7428 the wrong Emit call, which generates the wrong data.
7430 (ParameterReference::Emit, ::Store): same.
7432 (FieldExpr::AddressOf): Implement.
7434 * typemanager.cs: TypeManager: made public variable instead of
7437 * driver.cs: document --fatal.
7439 * report.cs (ErrorMessage, WarningMessage): new names for the old
7440 Error and Warning classes.
7442 * cs-parser.jay (member_access): Turn built-in access to types
7443 into a normal simplename
7445 2001-09-27 Ravi Pratap <ravi@ximian.com>
7447 * expression.cs (Invocation::BetterConversion): Fix to cope
7448 with q being null, since this was introducing a bug.
7450 * expression.cs (ConvertImplicit): Do built-in conversions first.
7452 2001-09-27 Ravi Pratap <ravi@ximian.com>
7454 * expression.cs (UserImplicitCast::Resolve): Fix bug.
7456 2001-09-27 Ravi Pratap <ravi@ximian.com>
7458 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
7459 I had introduced long ago (what's new ?).
7461 * expression.cs (UserImplicitCast::CanConvert): Static method to do
7462 the work of all the checking.
7463 (ConvertImplicit): Call CanConvert and only then create object if necessary.
7464 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
7466 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
7467 that is the right way.
7469 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
7470 overloading resolution. Use everywhere instead of cutting and pasting code.
7472 (Binary::ResolveOperator): Use MakeUnionSet.
7474 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
7475 we have to convert to bool types. Not complete yet.
7477 2001-09-27 Miguel de Icaza <miguel@ximian.com>
7479 * typemanager.cs (TypeManager::CSharpName): support ushort.
7481 * expression.cs (Expression::TryImplicitIntConversion): Attempts
7482 to provide an expression that performsn an implicit constant int
7483 conversion (section 6.1.6).
7484 (Expression::ConvertImplicitRequired): Reworked to include
7485 implicit constant expression conversions.
7487 (Expression::ConvertNumericExplicit): Finished.
7489 (Invocation::Emit): If InstanceExpression is null, then it means
7490 that we perform a call on this.
7492 2001-09-26 Miguel de Icaza <miguel@ximian.com>
7494 * expression.cs (Unary::Emit): Remove some dead code.
7495 (Probe): Implement Resolve and Emit for `is'.
7496 (Expression::ConvertImplicitRequired): Attempt to do constant
7497 expression conversions here. Maybe should be moved to
7498 ConvertImplicit, but I am not sure.
7499 (Expression::ImplicitLongConstantConversionPossible,
7500 Expression::ImplicitIntConstantConversionPossible): New functions
7501 that tell whether is it possible to apply an implicit constant
7502 expression conversion.
7504 (ConvertNumericExplicit): Started work on explicit numeric
7507 * cs-parser.jay: Update operator constants.
7509 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
7510 (Parameters::GetSignature): Hook up VerifyArgs here.
7511 (Parameters::VerifyArgs): Verifies that no two arguments have the
7514 * class.cs (Operator): Update the operator names to reflect the
7515 ones that the spec expects (as we are just stringizing the
7518 * expression.cs (Unary::ResolveOperator): Fix bug: Use
7519 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
7520 previous usage did only work for our methods.
7521 (Expression::ConvertImplicit): Handle decimal implicit numeric
7522 conversions as well.
7523 (Expression::InternalTypeConstructor): Used to invoke constructors
7524 on internal types for default promotions.
7526 (Unary::Emit): Implement special handling for the pre/post
7527 increment/decrement for overloaded operators, as they need to have
7528 the same semantics as the other operators.
7530 (Binary::ResolveOperator): ditto.
7531 (Invocation::ConversionExists): ditto.
7532 (UserImplicitCast::Resolve): ditto.
7534 2001-09-26 Ravi Pratap <ravi@ximian.com>
7536 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded
7537 operator, return after emitting body. Regression tests pass again !
7539 * expression.cs (ConvertImplicit): Take TypeContainer as first argument
7540 (Unary::ForceConversion, Binary::ForceConversion): Ditto.
7541 (Invocation::OverloadResolve): Ditto.
7542 (Invocation::BetterFunction, BetterConversion, ConversionExists): Ditto.
7544 * everywhere : update calls to the above methods accordingly.
7546 2001-09-26 Miguel de Icaza <miguel@ximian.com>
7548 * assign.cs (Assign): Make it inherit from ExpressionStatement.
7550 * expression.cs (ExpressionStatement): New base class used for
7551 expressions that can appear in statements, so that we can provide
7552 an alternate path to generate expression that do not leave a value
7555 (Expression::Emit, and all the derivatives): We no longer return
7556 whether a value is left on the stack or not. Every expression
7557 after being emitted leaves a single value on the stack.
7559 * codegen.cs (EmitContext::EmitStatementExpression): Use the
7560 facilties of ExpressionStatement if possible.
7562 * cs-parser.jay: Update statement_expression.

7570 * expression.cs (Binary::ResolveOperator): Had forgottten to set
7571 the type of the expression to the return type of the method if
7572 we have an overloaded operator match ! The regression tests pass again !
7573 (Unary::ResolveOperator): Ditto.
7575 * expression.cs (Invocation::ConversionExists): Correct the member lookup
7576 to find "op_Implicit", not "implicit" ;-)
7577 (UserImplicitCast): New class to take care of user-defined implicit conversions.
7578 (ConvertImplicit, ForceConversion): Take TypeContainer argument
7580 * everywhere : Correct calls to the above accordingly.
7582 * expression.cs (UserImplicitCast::Resolve, ::Emit): Implement.
7583 (ConvertImplicit): Do user-defined conversion if it exists.
7585 2001-09-24 Miguel de Icaza <miguel@ximian.com>
7587 * assign.cs: track location.
7588 (Resolve): Use implicit conversions on assignment.
7590 * literal.cs: Oops. Not good, Emit of short access values should

7593 * expression.cs (Unary::Emit): Emit code for -expr.
7595 (Unary::ResolveOperator): Handle `Substract' for non-constants
7596 (substract from zero from the non-constants).

7631 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
7632 Also take an additional TypeContainer argument.
7634 * All over : Pass in TypeContainer as argument to OverloadResolve.
7636 * typemanager.cs (CSharpName): Update to check for the string type and return
7639 * expression.cs (Invocation::FullMethodDesc): New static method to return a string fully describing
7642 2001-09-21 Ravi Pratap <ravi@ximian.com>
7644 * expression.cs (Invocation::OverloadResolve): Re-write to conform more to the spec.
7645 (Invocation::BetterFunction): Implement.
7646 (Invocation::BetterConversion): Implement.
7647 (Invocation::ConversionExists): Skeleton, no implementation yet.
7649 Okay, things work fine !
7651 2001-09-21 Miguel de Icaza <miguel@ximian.com>
7653 * typemanager.cs: declare and load enum_type, delegate_type and
7656 * expression.cs (Expression::Emit): Now emit returns a value that
7657 tells whether a value is left on the stack or not. This strategy
7658 might be reveted tomorrow with a mechanism that would address
7659 multiple assignments.
7660 (Expression::report118): Utility routine to report mismatches on
7663 (Unary::Report23): Report impossible type/operator combination
7666 (Unary::IsIncrementableNumber): Whether the type can be

7700 * expression.cs (SimpleName::ResolveSimpleName): Error if we can
7703 * cs-parser.jay (QualifierIdentifier): Pass location to SimpleName
7706 * statement.cs (Block::EmitMeta): Reuse the count across all the variables,
7707 otherwise nested blocks end up with the same index.
7709 * codegen.cs (CodeGen::EmitTopBlock): Pass initial sequence
7711 * expression.cs: Instead of having FIXMEs in the Resolve
7712 functions, throw exceptions so it is obvious that we are facing a
7715 * cs-parser.jay (invocation_expression): Pass Location information.
7717 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
7718 Use a basename for those routines because .NET does not like paths

7724 2001-09-19 Miguel de Icaza <miguel@ximian.com>
7726 * typemanager.cs (TypeManager::CoreLookupType): A function to make sure that we
7727 are loading the correct data types (throws an exception if not).

7730 * expression.cs (Unary::ResolveOperator): return the child
7731 expression for expressions which are just +expr.
7732 (Unary::ResolveOperator): Return negative literals for -LITERAL
7733 expressions (otherwise they are Unary {Literal}).
7734 (Invocation::Badness): Take into account `Implicit constant
7735 expression conversions'.
7737 * literal.cs (LongLiteral): Implement long literal class.
7738 (IntLiteral): export the `Value' of the intliteral.
7740 2001-09-19 Ravi Pratap <ravi@ximian.com>
7742 * expression.cs (Binary::Emit): Finally get the emission right ! Woo!
7744 * class.cs (Operator::Define): Change the methodname prefix to 'op_'
7745 instead of 'Operator'
7747 * expression.cs (Binary::ResolveOperator): Update accordingly.
7748 (Unary::Operator): Change names to 'Add' and 'Subtract' instead 'Plus'
7751 * cs-parser.jay (unary_expression): Update to use the new names.

7755 * expression.cs (Unary::Resolve): Implement.
7756 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
7757 operators are found instead of making noise ;-)

7759 Binary::ResolveOperator does for Binary expressions.
7760 (Unary.method, .Arguments): Add.
7761 (Unary::OperName): Implement.
7762 (Unary::ForceConversion): Copy and Paste !
7764 * class.cs (Operator::Define): Fix a small bug for the case when we have
7767 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
7768 for the inbuilt operators. Only overloading works for now ;-)
7770 2001-09-18 Miguel de Icaza <miguel@ximian.com>

7788 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
7789 the last instruction contains a return opcode to avoid generating
7790 the last `ret' instruction (this generates correct code, and it is
7791 nice to pass the peverify output).
7793 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
7794 initializer for static and instance variables.
7795 (Constructor::Emit): Allow initializer to be null in the case of
7796 static constructors. Only emit initializer for instance

7809 * driver.cs: Stop compilation if there are parse errors.
7811 * cs-parser.jay (constructor_declaration): Provide default base

7814 initializers if none was specified.
7815 Catch the fact that constructors should not have parameters.
7817 * class.cs: Do not emit parent class initializers for static
7818 constructors, that should be flagged as an error.
7820 2001-09-18 Ravi Pratap <ravi@ximian.com>
7822 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.

7852 (Expression::MemberLookup): Provide a version that allows to
7853 specify the MemberTypes and BindingFlags.
7855 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
7856 so it was not fetching variable information from outer blocks.
7858 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
7859 Beforefieldinit as it was buggy.
7861 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200

7958 * modifiers.cs: Do not use `parent', instead use the real type
7959 container to evaluate permission settings.

7962 have to cope with the
7964 2001-09-14 Ravi Pratap <ravi@ximian.com>
7966 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to

7971 * driver.cs: Added --parse option that only parses its input files
7974 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
7975 incorrect. IsTopLevel is not used to tell whether an object is
7976 root_types or not (that can be achieved by testing this ==
7977 root_types). But to see if this is a top-level *class* (not
7978 necessarly our "toplevel" container).
7980 2001-09-14 Ravi Pratap <ravi@ximian.com>
7982 * enum.cs (Enum::Define): Modify to call the Lookup method on the

7987 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
7988 Modifiers.TypeAttr. This should just be a call to that method.
7990 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
7991 object so that we can determine if we are top-level or not.
7993 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
7996 * enum.cs (Enum::Define): Ditto.
7998 * modifiers.cs (FieldAttr): Re-write.

8002 to precisely that info.
8004 * modifiers.cs (MethodAttr): Re-write.
8005 (EventAttr): Remove altogether as there seems to be no ostensible use for it.

8010 2001-09-13 Miguel de Icaza <miguel@ximian.com>
8012 * expression.cs (MemberLookup): Fruitless attempt to lookup
8013 constructors. Maybe I need to emit default constructors? That
8014 might be it (currently .NET emits this for me automatically).
8015 (Invocation::OverloadResolve): Cope with Arguments == null.
8016 (Invocation::EmitArguments): new function, shared by the new

8038 objects that we might have around.
8040 (Populate): Only initialize method_builders_to_methods once.
8042 * expression.cs (PropertyExpr): Initialize type from the
8045 * codegen.cs (EmitContext::EmitBoolExpression): Use propper

8050 (Binary::ResolveOperator): Set the return type to boolean for
8051 comparission operators
8053 * typemanager.cs: Remove debugging print code.
8055 (Invocation::Resolve): resolve type.
8057 * class.cs: Allocate a MemberInfo of the correct size, as the code
8058 elsewhere depends on the test to reflect the correct contents.
8060 (Method::) Keep track of parameters, due to System.Reflection holes
8062 (TypeContainer::Populate): Keep track of MethodBuilders to Method
8065 (TypeContainer::FindMembers): Use ArrayList and then copy an array
8066 of the exact size and return that.
8068 (Class::LookupMethodByBuilder): New function that maps
8069 MethodBuilders to its methods. Required to locate the information
8070 on methods because System.Reflection bit us again.
8072 * support.cs: New file, contains an interface ParameterData and
8073 two implementations: ReflectionParameters and InternalParameters
8074 used to access Parameter information. We will need to grow this
8077 * expression.cs (Invocation::GetParameterData): implement a cache
8078 and a wrapper around the ParameterData creation for methods.
8079 (Invocation::OverloadResolve): Use new code.
8081 2001-09-13 Ravi Pratap <ravi@ximian.com>

8135 2001-09-12 Ravi Pratap <ravi@ximian.com>
8137 * class.cs (TypeContainer::FindMembers): Method which does exactly
8138 what Type.FindMembers does, only we don't have to use reflection. No

8238 already might have something already fully qualified like
8239 'System.Console.WriteLine'

8390 will is used during the tree rewriting as we resolve them during

8493 (namespace_declarations): Non-reducing rule - comment out.
8495 * enum.cs (Enum::AddEnum): Rename to AddEnumMember as I was getting confused
8496 with TypeContainer::AddEnum.

8508 (Event.EventBuilder): New member.
8510 * class.cs (TypeContainer::Populate): Update to define all enums and events
8512 (Events): New property for the events arraylist we hold. Shouldn't we move to using

8515 2001-08-31 Ravi Pratap <ravi@che.iitm.ac.in>
8517 * class.cs (Property): Revamp to use the convention of making fields readonly.

8563 (catch_clauses): Modify accordingly.
8564 (opt_catch_clauses): New production to use in try_statement
8565 (try_statement): Revamp. Basically, we get rid of one unnecessary rule
8566 and re-write the code in the actions to extract the specific and
8567 general catch clauses by being a little smart ;-)
8569 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
8570 Hooray, try and catch statements parse fine !
8572 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
8574 * statement.cs (Block::GetVariableType): Fix logic to extract the type
8575 string from the hashtable of variables.
8577 * cs-parser.jay (event_accessor_declarations): Trivial fix. Man, how did

8579 (catch_clauses): Fixed gross error which made Key and Value of the
8580 DictionaryEntry the same : $1 !!
8582 2001-08-28 Ravi Pratap <ravi@che.iitm.ac.in>
8584 * cs-tokenizer.cs (initTokens): Add keywords 'add' and 'remove'
8586 * cs-parser.jay (event_declaration): Correct to remove the semicolon

8592 information about indexer_declarator.
8593 (indexer_declarator): Implement actions.
8594 (parsing_indexer): New local boolean used to keep track of whether

8622 concatenating all the commas together, just as they appear.
8623 (opt_dim_separators): Modify accordingly
8624 (rank_specifiers): Update accordingly. Basically do the same
8625 thing - instead, collect the brackets here.

8628 instead of ignoring the rank_specifiers.
8629 (expression_list): Implement to collect the expressions

8651 constructors instead of returning null.
8653 2001-08-26 Miguel de Icaza <miguel@ximian.com>
8655 * typemanager.cs (InitCoreTypes): Initialize the various core
8656 types after we have populated the type manager with the user
8657 defined types (this distinction will be important later while
8658 compiling corlib.dll)
8660 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
8661 on Expression Classification. Now all expressions have a method
8662 `Resolve' and a method `Emit'.
8664 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
8665 generation from working. Also add some temporary debugging
8668 2001-08-24 Miguel de Icaza <miguel@ximian.com>
8670 * codegen.cs: Lots of code generation pieces. This is only the
8671 beginning, will continue tomorrow with more touches of polish. We
8672 handle the fundamentals of if, while, do, for, return. Others are
8673 trickier and I need to start working on invocations soon.
8675 * gen-treedump.cs: Bug fix, use s.Increment here instead of
8678 * codegen.cs (EmitContext): New struct, used during code
8679 emission to keep a context. Most of the code generation will be
8682 * cs-parser.jay: Add embedded blocks to the list of statements of
8683 this block. So code generation proceeds in a top down fashion.
8685 2001-08-23 Miguel de Icaza <miguel@ximian.com>

8696 (Block::Child): Child Linker.
8697 (Block::EmitVariables): Emits IL variable declarations.
8699 * class.cs: Drop support for MethodGroups here, delay until
8701 (Method::): Applied the same simplification that I did before, and
8702 move from Properties to public readonly fields.
8703 (Method::ParameterTypes): Returns the parameter types for the
8704 function, and implements a cache that will be useful later when I
8705 do error checking and the semantic analysis on the methods is
8707 (Constructor::GetCallingConvention): Renamed from CallingConvetion
8708 and made a method, optional argument tells whether this is a class
8709 or a structure to apply the `has-this' bit.
8710 (Method::GetCallingConvention): Implement, returns the calling
8712 (Method::Define): Defines the type, a second pass is performed
8713 later to populate the methods.

8735 and the default static constructor.
8737 (Constructor::) Another class that starts using `public readonly'
8738 instead of properties.
8740 (Constructor::IsDefault): Whether this is a default constructor.
8742 (Field::) use readonly public fields instead of properties also.
8744 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
8745 track of static constructors; If none is used, turn on
8746 BeforeFieldInit in the TypeAttributes.
8748 * cs-parser.jay (opt_argument_list): now the return can be null
8749 for the cases where there are no arguments.
8751 (constructor_declarator): If there is no implicit `base' or
8752 `this', then invoke the default parent constructor.
8754 * modifiers.cs (MethodAttr): New static function maps a set of
8755 modifiers flags into a MethodAttributes enum
8756 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
8757 MethodAttr, TypeAttr to represent the various mappings where the
8759 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
8761 2001-08-19 Miguel de Icaza <miguel@ximian.com>

8767 for interface indexers.
8769 2001-08-17 Miguel de Icaza <miguel@ximian.com>
8771 * interface.cs (InterfaceMemberBase): Now we track the new status
8774 (PopulateProperty): Implement property population. Woohoo! Got
8775 Methods and Properties going today.
8777 Removed all the properties for interfaces, and replaced them with
8778 `public readonly' fields.
8780 2001-08-16 Miguel de Icaza <miguel@ximian.com>
8782 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
8783 initialize their hashtables/arraylists only when they are needed
8784 instead of doing this always.
8786 * parameter.cs: Handle refs and out parameters.
8788 * cs-parser.jay: Use an ArrayList to construct the arguments
8789 instead of the ParameterCollection, and then cast that to a
8792 * parameter.cs: Drop the use of ParameterCollection and use
8793 instead arrays of Parameters.
8795 (GetParameterInfo): Use the Type, not the Name when resolving
8798 2001-08-13 Miguel de Icaza <miguel@ximian.com>
8800 * parameter.cs: Eliminate the properties Name, Type and ModFlags,

8812 2001-08-08 Miguel de Icaza <miguel@ximian.com>
8814 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
8815 this System.Reflection code is. Kudos to Microsoft
8817 * typemanager.cs: Implement a type cache and avoid loading all
8818 types at boot time. Wrap in LookupType the internals. This made
8819 the compiler so much faster. Wow. I rule!
8821 * driver.cs: Make sure we always load mscorlib first (for
8822 debugging purposes, nothing really important).
8824 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
8825 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
8827 * rootcontext.cs: Lookup types on their namespace; Lookup types
8828 on namespaces that have been imported using the `using' keyword.
8830 * class.cs (TypeContainer::TypeAttr): Virtualize.
8831 (Class::TypeAttr): Return attributes suitable for this bad boy.
8832 (Struct::TypeAttr): ditto.
8833 Handle nested classes.
8834 (TypeContainer::) Remove all the type visiting code, it is now
8835 replaced with the rootcontext.cs code

8845 2001-08-04 Miguel de Icaza <miguel@ximian.com>
8849 * class.cs (Struct::Struct): set the SEALED flags after
8850 checking the modifiers.
8851 (TypeContainer::TypeAttr): new property, returns the
8852 TypeAttributes for a class.
8854 * cs-parser.jay (type_list): Oops, list production was creating a
8855 new list of base types.
8857 * rootcontext.cs (StdLib): New property.
8858 (GetInterfaceTypeByName): returns an interface by type name, and
8859 encapsulates error handling here.
8860 (GetInterfaces): simplified.
8861 (ResolveTree): Encapsulated all the tree resolution here.
8862 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
8865 * driver.cs: Add support for --nostdlib, to avoid loading the
8867 (Main): Do not put tree resolution here.
8869 * rootcontext.cs: Beginning of the class resolution.
8871 2001-08-03 Miguel de Icaza <miguel@ximian.com>
8873 * rootcontext.cs: Provide better error reporting.
8875 * cs-parser.jay (interface_base): set our $$ to be interfaces.

8886 the type on the global type hash, and allows us to close it at the
8889 2001-08-02 Miguel de Icaza <miguel@ximian.com>
8891 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
8892 RecordInterface instead.
8894 * cs-parser.jay: Updated to reflect changes above.
8896 * decl.cs (Definition): Keep track of the TypeBuilder type that
8897 represents this type here. Not sure we will use it in the long
8898 run, but wont hurt for now.
8900 * driver.cs: Smaller changes to accomodate the new code.
8902 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly

8913 * cs-parser.jay: Add a second production for delegate_declaration
8916 (enum_body): Put an opt_comma here instead of putting it on
8917 enum_body or enum_member_declarations so we can handle trailing
8918 commas on enumeration members. Gets rid of a shift/reduce.
8920 (type_list): Need a COMMA in the middle.
8922 (indexer_declaration): Tell tokenizer to recognize get/set
8924 * Remove old targets.

8941 representation and the defined types available to the program.
8943 * gen-treedump.cs: adjust for new convention.
8945 * type.cs: Split out the type manager, and the assembly builder

8976 * decl.cs: Added `Define' abstract method.
8977 (InTransit): new property, used to catch recursive definitions.
8979 * interface.cs: Implement `Define'.
8981 * modifiers.cs: Map Modifiers.constants to
8982 System.Reflection.TypeAttribute flags.
8984 * class.cs: Keep track of types and user-defined types.
8985 (BuilderInit): New method for creating an assembly
8986 (ResolveType): New function to launch the resolution process, only
8987 used by interfaces for now.
8989 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
8990 that are inserted into the name space.
8992 2001-06-08 Miguel de Icaza <miguel@ximian.com>
8994 * ARGH. I have screwed up my tree so many times due to the use of
8995 rsync rather than using CVS. Going to fix this at once.
8997 * driver.cs: Objetify driver. Load assemblies, use assemblies to
9000 2001-06-07 Miguel de Icaza <miguel@ximian.com>
9002 * Experiment successful: Use System.Type rather that our own
9005 2001-05-25 Miguel de Icaza <miguel@ximian.com>
9007 * cs-parser.jay: Removed nsAliases from here.
9009 Use new namespaces, handle `using XXX;'
9011 * namespace.cs: Reimplemented namespace handling, use a recursive
9012 definition of the class. Now we can keep track of using clauses
9013 and catch invalid using clauses.
9015 2001-05-24 Miguel de Icaza <miguel@ximian.com>
9017 * gen-treedump.cs: Adapted for all the renaming.
9019 * expression.cs (Expression): this class now has a Type property
9020 which returns an expression Type.
9022 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
9023 `Type', as this has a different meaning now in the base
9025 2001-05-22 Miguel de Icaza <miguel@ximian.com>
9027 * interface.cs, class.cs: Removed from all the sources the
9028 references to signature computation, as we can not do method
9029 signature computation during the parsing time, as we are not
9030 trying to solve at that point distinguishing:
9034 void a (NS.Blah x) {}
9037 Which depending on the context might be valid or not, as we do not
9038 know if Blah is the same thing as NS.Blah at that point.
9040 * Redid everything so the code uses TypeRefs now instead of
9041 Types. TypeRefs are just temporary type placeholders, that need
9042 to be resolved. They initially have a pointer to a string and the
9043 current scope in which they are used. This is used later by the
9044 compiler to resolve the reference to an actual Type.
9046 * DeclSpace is no longer a CIR.Type, and neither are
9047 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
9048 are all DeclSpaces, but no Types.
9050 * type.cs (TypeRefManager): This implements the TypeRef manager,
9051 which keeps track of all the types that need to be resolved after
9052 the parsing has finished.

9056 * ARGH. We are going to have to store `foreach' as a class rather
9057 than resolving it, as we need to verify error 1579 after name
9058 resolution. *OR* we could keep a flag that says `This request to
9059 IEnumerator comes from a foreach statement' which we can then use
9060 to generate the error.
9062 2001-05-10 Miguel de Icaza <miguel@ximian.com>
9064 * class.cs (TypeContainer.AddMethod): we now add methods to the
9065 MethodGroup instead of the method hashtable.
9067 * expression.cs: Add MethodGroup abstraction, which gets us one
9068 step closer to the specification in the way we handle method
9071 * cs-parser.jay (primary_expression): qualified_identifier now
9072 tried to match up an identifier to a local variable reference or
9073 to a parameter reference.
9075 current_local_parameters is now a parser global variable that
9076 points to the current parameters for the block, used during name
9079 (property_declaration): Now creates an implicit `value' argument to
9082 2001-05-09 Miguel de Icaza <miguel@ximian.com>
9084 * parameter.cs: Do not use `param' arguments as part of the
9085 signature, per the spec.
9087 2001-05-08 Miguel de Icaza <miguel@ximian.com>
9089 * decl.cs: Base class for classes, structs and interfaces. This
9090 is the "Declaration Space"
9092 * cs-parser.jay: Use CheckDef for checking declaration errors
9093 instead of having one on each function.
9095 * class.cs: Factor out some code for handling error handling in
9096 accordance to the "Declarations" section in the "Basic Concepts"
9097 chapter in the ECMA C# spec.
9099 * interface.cs: Make all interface member classes derive from
9100 InterfaceMemberBase.
9102 2001-05-07 Miguel de Icaza <miguel@ximian.com>
9104 * Many things: all interfaces are parsed and generated in
9105 gen-treedump. Support for member variables, constructors,
9106 destructors, properties, constants is there.
9108 Beginning of the IL backend, but very little done, just there for
9111 2001-04-29 Miguel de Icaza <miguel@ximian.com>
9113 * cs-parser.jay: Fix labeled statement.
9115 * cs-tokenizer.cs (escape): Escape " and ' always.
9116 ref_line, ref_name: keep track of the line/filename as instructed
9117 by #line by the compiler.
9120 2001-04-27 Miguel de Icaza <miguel@ximian.com>
9122 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
9123 to match the values in System.CodeDOM.
9125 Divid renamed to Divide.
9127 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
9129 (Statements.set): remove.
9131 * System.CodeDOM/CodeCatchClause.cs: always have a valid
9134 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
9135 falseStatements always have valid values.
9137 * cs-parser.jay: Use System.CodeDOM now.
