1 2002-08-16 Martin Baulig <martin@gnome.org>
3 * decl.cs (DeclSpace.Define): Splitted this in Define and
4 DefineMembers. DefineMembers is called first and initializes the
7 * rootcontext.cs (RootContext.DefineMembers): New function. Calls
8 DefineMembers() on all our DeclSpaces.
10 * class.cs (TypeContainer.Define): Moved all code to DefineMembers(),
11 but call DefineMembers() on all nested interfaces. We call their
12 Define() in our new Define() function.
14 * interface.cs (Interface): Implement IMemberContainer.
15 (Interface.Define): Moved all code except the attribute stuf to
17 (Interface.DefineMembers): Initialize the member cache.
19 * typemanager.cs (IMemberFinder): Removed this interface, we don't
20 need this anymore since we can use MemberCache.FindMembers directly.
22 2002-08-19 Martin Baulig <martin@gnome.org>
24 * typemanager.cs (MemberCache): When creating the cache for an
25 interface type, add all inherited members.
26 (TypeManager.MemberLookup_FindMembers): Changed `ref bool searching'
27 to `out bool used_cache' and documented it.
28 (TypeManager.MemberLookup): If we already used the cache in the first
29 iteration, we don't need to do the interfaces check.
31 2002-08-19 Martin Baulig <martin@gnome.org>
33 * decl.cs (DeclSpace.FindMembers): New abstract method. Moved this
34 here from IMemberFinder and don't implement this interface anymore.
35 (DeclSpace.MemberCache): Moved here from IMemberFinder.
37 * typemanager.cs (IMemberFinder): This interface is now only used by
38 classes which actually support the member cache.
39 (TypeManager.builder_to_member_finder): Renamed to builder_to_declspace
40 since we only put DeclSpaces into this Hashtable.
41 (MemberLookup_FindMembers): Use `builder_to_declspace' if the type is
42 a dynamic type and TypeHandle.GetTypeHandle() otherwise.
44 2002-08-16 Martin Baulig <martin@gnome.org>
46 * typemanager.cs (ICachingMemberFinder): Removed.
47 (IMemberFinder.MemberCache): New property.
48 (TypeManager.FindMembers): Merged this with RealFindMembers().
49 This function will never be called from TypeManager.MemberLookup()
50 so we can't use the cache here, just the IMemberFinder.
51 (TypeManager.MemberLookup_FindMembers): Check whether the
52 IMemberFinder has a MemberCache and call the cache's FindMembers
54 (MemberCache): Rewrote larger parts of this yet another time and
57 2002-08-15 Miguel de Icaza <miguel@ximian.com>
59 * driver.cs (LoadArgs): Support quoting.
61 (Usage): Show the CSC-like command line arguments.
63 Improved a few error messages.
65 2002-08-15 Martin Baulig <martin@gnome.org>
67 * typemanager.cs (IMemberContainer.Type): New property.
68 (IMemberContainer.IsInterface): New property.
70 The following changes are conditional to BROKEN_RUNTIME, which is
71 defined at the top of the file.
73 * typemanager.cs (MemberCache.MemberCache): Don't add the base
74 class'es members, but add all members from TypeHandle.ObjectType
75 if we're an interface.
76 (MemberCache.AddMembers): Set the Declared flag if member.DeclaringType
78 (MemberCache.CacheEntry.Container): Removed this field.
79 (TypeHandle.GetMembers): Include inherited members.
81 2002-08-14 Gonzalo Paniagua Javier <gonzalo@ximian.com>
83 * typemanager.cs: fixed compilation and added a comment on a field that
86 2002-08-15 Martin Baulig <martin@gnome.org>
88 * class.cs (ConstructorInitializer.Resolve): In the
89 Expression.MemberLookup call, use the queried_type as
92 * typemanager.cs (IMemberContainer.GetMembers): Removed the `bool
93 declared' attribute, it's always true.
94 (IMemberContainer.Parent, IMemberContainer.Name): New properties.
95 (TypeManager.MemberLookup_FindMembers): [FIXME FIXME FIXME] Added
96 temporary wrapper for FindMembers which tells MemberLookup whether
97 members from the base classes are included in the return value.
98 This will go away soon.
99 (TypeManager.MemberLookup): Use this temporary hack here; once the
100 new MemberCache is completed, we don't need to do the DeclaredOnly
101 looping here anymore since the MemberCache will take care of this.
102 (TypeManager.IsSubclassOrNestedChildOf): Allow `type == parent'.
103 (MemberCache): When creating the MemberCache for a class, get
104 members from the current class and all its base classes.
105 (MemberCache.CacheEntry.Container): New field. This is a
106 temporary hack until the Mono runtime is fixed to distinguish
107 between ReflectedType and DeclaringType. It allows us to use MCS
108 with both the MS runtime and the unfixed Mono runtime without
109 problems and without accecting performance.
110 (MemberCache.SearchMembers): The DeclaredOnly looping from
111 TypeManager.MemberLookup is now done here.
113 2002-08-14 Martin Baulig <martin@gnome.org>
115 * statement.cs (MyStructInfo.MyStructInfo): Don't call
116 Type.GetFields on dynamic types but get the fields from the
117 corresponding TypeContainer.
118 (MyStructInfo.GetStructInfo): Added check for enum types.
120 * typemanager.cs (MemberList.IsSynchronized): Implemented.
121 (MemberList.SyncRoot): Implemented.
122 (TypeManager.FilterWithClosure): No need to check permissions if
123 closure_start_type == closure_invocation_type, don't crash if
124 closure_invocation_type is null.
126 2002-08-13 Martin Baulig <martin@gnome.org>
128 Rewrote TypeContainer.FindMembers to use a member cache. This
129 gives us a speed increase of about 35% for the self-hosting MCS
130 build and of about 15-20% for the class libs (both on GNU/Linux).
132 * report.cs (Timer): New class to get enhanced profiling. This
133 whole class is "TIMER" conditional since it remarkably slows down
136 * class.cs (MemberList): New class. This is an IList wrapper
137 which we're now using instead of passing MemberInfo[]'s around to
138 avoid copying this array unnecessarily.
139 (IMemberFinder.FindMember): Return a MemberList, not a MemberInfo [].
140 (ICachingMemberFinder, IMemberContainer): New interface.
141 (TypeManager.FilterWithClosure): If `criteria' is null, the name
142 has already been checked, otherwise use it for the name comparision.
143 (TypeManager.FindMembers): Renamed to RealMemberFinder and
144 provided wrapper which tries to use ICachingMemberFinder.FindMembers
145 if possible. Returns a MemberList, not a MemberInfo [].
146 (TypeHandle): New class, implements IMemberContainer. We create
147 one instance of this class per type, it contains a MemberCache
148 which is used to do the member lookups.
149 (MemberCache): New class. Each instance of this class contains
150 all members of a type and a name-based hash table.
151 (MemberCache.FindMembers): This is our new member lookup
152 function. First, it looks up all members of the requested name in
153 the hash table. Then, it walks this list and sorts out all
154 applicable members and returns them.
156 2002-08-13 Martin Baulig <martin@gnome.org>
158 In addition to a nice code cleanup, this gives us a performance
159 increase of about 1.4% on GNU/Linux - not much, but it's already
160 half a second for the self-hosting MCS compilation.
162 * typemanager.cs (IMemberFinder): New interface. It is used by
163 TypeManager.FindMembers to call FindMembers on a TypeContainer,
164 Enum, Delegate or Interface.
165 (TypeManager.finder_to_member_finder): New PtrHashtable.
166 (TypeManager.finder_to_container): Removed.
167 (TypeManager.finder_to_delegate): Removed.
168 (TypeManager.finder_to_interface): Removed.
169 (TypeManager.finder_to_enum): Removed.
171 * interface.cs (Interface): Implement IMemberFinder.
173 * delegate.cs (Delegate): Implement IMemberFinder.
175 * enum.cs (Enum): Implement IMemberFinder.
177 * class.cs (TypeContainer): Implement IMemberFinder.
179 2002-08-12 Martin Baulig <martin@gnome.org>
181 * ecore.cs (TypeExpr.DoResolveType): Mark this as virtual.
183 2002-08-12 Martin Baulig <martin@gnome.org>
185 * ecore.cs (ITypeExpression): New interface for expressions which
187 (TypeExpression): Renamed to TypeLookupExpression.
188 (Expression.DoResolve): If we're doing a types-only lookup, the
189 expression must implement the ITypeExpression interface and we
190 call DoResolveType() on it.
191 (SimpleName): Implement the new ITypeExpression interface.
192 (SimpleName.SimpleNameResolve): Removed the ec.OnlyLookupTypes
193 hack, the situation that we're only looking up types can't happen
194 anymore when this method is called. Moved the type lookup code to
195 DoResolveType() and call it.
196 (SimpleName.DoResolveType): This ITypeExpression interface method
197 is now doing the types-only lookup.
198 (TypeExpr, TypeLookupExpression): Implement ITypeExpression.
199 (ResolveFlags): Added MaskExprClass.
201 * expression.cs (MemberAccess): Implement the ITypeExpression
203 (MemberAccess.DoResolve): Added support for a types-only lookup
204 when we're called via ITypeExpression.DoResolveType().
205 (ComposedCast): Implement the ITypeExpression interface.
207 * codegen.cs (EmitContext.OnlyLookupTypes): Removed. Call
208 Expression.Resolve() with ResolveFlags.Type instead.
210 2002-08-12 Martin Baulig <martin@gnome.org>
212 * interface.cs (Interface.Define): Apply attributes.
214 * attribute.cs (Attribute.ApplyAttributes): Added support for
215 interface attributes.
217 2002-08-11 Martin Baulig <martin@gnome.org>
219 * statement.cs (Block.Emit): Only check the "this" variable if we
220 do not always throw an exception.
222 * ecore.cs (PropertyExpr.DoResolveLValue): Implemented, check
223 whether the property has a set accessor.
225 2002-08-11 Martin Baulig <martin@gnome.org>
227 Added control flow analysis support for structs.
229 * ecore.cs (ResolveFlags): Added `DisableFlowAnalysis' to resolve
230 with control flow analysis turned off.
231 (IVariable): New interface.
232 (SimpleName.SimpleNameResolve): If MemberAccess.ResolveMemberAccess
233 returns an IMemberExpr, call DoResolve/DoResolveLValue on it.
234 (FieldExpr.DoResolve): Resolve the instance expression with flow
235 analysis turned off and do the definite assignment check after the
236 resolving when we know what the expression will resolve to.
238 * expression.cs (LocalVariableReference, ParameterReference):
239 Implement the new IVariable interface, only call the flow analysis
240 code if ec.DoFlowAnalysis is true.
241 (This): Added constructor which takes a Block argument. Implement
242 the new IVariable interface.
243 (MemberAccess.DoResolve, MemberAccess.DoResolveLValue): Call
244 DoResolve/DoResolveLValue on the result of ResolveMemberLookup().
245 This does the definite assignment checks for struct members.
247 * class.cs (Constructor.Emit): If this is a non-static `struct'
248 constructor which doesn't have any initializer, call
249 Block.AddThisVariable() to tell the flow analysis code that all
250 struct elements must be initialized before control returns from
253 * statement.cs (MyStructInfo): New public class.
254 (UsageVector.this [VariableInfo vi]): Added `int field_idx'
255 argument to this indexer. If non-zero, check an individual struct
256 member, not the whole struct.
257 (FlowBranching.CheckOutParameters): Check struct members.
258 (FlowBranching.IsVariableAssigned, SetVariableAssigned): Added
259 overloaded versions of these methods which take an additional
260 `int field_idx' argument to check struct members.
261 (FlowBranching.IsParameterAssigned, SetParameterAssigned): Added
262 overloaded versions of these methods which take an additional
263 `string field_name' argument to check struct member.s
264 (VariableInfo): Implement the IVariable interface.
265 (VariableInfo.StructInfo): New public property. Returns the
266 MyStructInfo instance of the variable if it's a struct or null.
267 (Block.AddThisVariable): New public method. This is called from
268 Constructor.Emit() for non-static `struct' constructor which do
269 not have any initializer. It creates a special variable for the
270 "this" instance variable which will be checked by the flow
271 analysis code to ensure that all of the struct's fields are
272 initialized before control returns from the constructor.
273 (UsageVector): Added support for struct members. If a
274 variable/parameter is a struct with N members, we reserve a slot
275 in the usage vector for each member. A struct is considered fully
276 initialized if either the struct itself (slot 0) or all its
277 members are initialized.
279 2002-08-08 Martin Baulig <martin@gnome.org>
281 * driver.cs (Driver.MainDriver): Only report an error CS5001
282 if there were no compilation errors.
284 * codegen.cs (EmitContext.EmitContext): Use the DeclSpace's
285 `UnsafeContext' property to determine whether the parent is in
286 unsafe context rather than checking the parent's ModFlags:
287 classes nested in an unsafe class are unsafe as well.
289 2002-08-08 Martin Baulig <martin@gnome.org>
291 * statement.cs (UsageVector.MergeChildren): Distinguish between
292 `Breaks' and `Returns' everywhere, don't set `Breaks' anymore if
293 we return. Added test17() and test18() to test-154.cs.
295 2002-08-08 Martin Baulig <martin@gnome.org>
297 * typemanager.cs (TypeManager.FilterWithClosure): If we have
298 Family access, make sure the invoking type isn't a subclass of the
299 queried type (that'd be a CS1540).
301 * ecore.cs (Expression.MemberLookup): Added overloaded version of
302 this method which takes an additional `Type invocation_type'.
304 * expression.cs (BaseAccess.DoResolve): Use the base type as
305 invocation and query type.
306 (MemberAccess.DoResolve): If the lookup failed and we're about to
307 report a CS0122, try a lookup with the ec.ContainerType - if this
308 succeeds, we must report a CS1540.
310 2002-08-08 Martin Baulig <martin@gnome.org>
312 * ecore.cs (IMemberExpr): Added `bool IsInstance' property.
313 (MethodGroupExpr): Implement the IMemberExpr interface.
315 * expression (MemberAccess.ResolveMemberAccess): No need to have
316 any special code for MethodGroupExprs anymore, they're now
319 2002-08-08 Martin Baulig <martin@gnome.org>
321 * typemanager.cs (TypeManager.FilterWithClosure): Check Assembly,
322 Family, FamANDAssem and FamORAssem permissions.
323 (TypeManager.IsSubclassOrNestedChildOf): New public method.
325 2002-08-08 Martin Baulig <martin@gnome.org>
327 * statement.cs (FlowBranchingType): Added LOOP_BLOCK.
328 (UsageVector.MergeChildren): `break' breaks unless we're in a switch
331 Thu Aug 8 10:28:07 CEST 2002 Paolo Molaro <lupus@ximian.com>
333 * driver.cs: implemented /resource option to embed managed resources.
335 2002-08-07 Martin Baulig <martin@gnome.org>
337 * class.cs (FieldBase.Initializer): Renamed to `init' and made private.
338 (FieldBase.HasFieldInitializer): New public property.
339 (FieldBase.GetInitializerExpression): New public method. Resolves and
340 returns the field initializer and makes sure it is only resolved once.
341 (TypeContainer.EmitFieldInitializers): Call
342 FieldBase.GetInitializerExpression to get the initializer, this ensures
343 that it isn't resolved multiple times.
345 * codegen.cs (EmitContext): Added `bool IsFieldInitialier'. This tells
346 the resolving process (SimpleName/MemberLookup) that we're currently
347 emitting a field initializer (which must not access any instance members,
348 this is an error CS0236).
350 * ecore.cs (SimpleName.Error_ObjectRefRequired): Added EmitContext
351 argument, if the `IsFieldInitializer' flag is set, we must report and
352 error CS0236 and not an error CS0120.
354 2002-08-07 Martin Baulig <martin@gnome.org>
356 * ecore.cs (IMemberExpr): New public interface.
357 (FieldExpr, PropertyExpr, EventExpr): Implement IMemberExpr.
358 (SimpleName.SimpleNameResolve): Call MemberAccess.ResolveMemberAccess
359 if the expression is an IMemberExpr.
361 * expression.cs (MemberAccess.ResolveMemberAccess): Allow `left'
362 to be null, implicitly default to `this' if we're non-static in
363 this case. Simplified the code a lot by using the new IMemberExpr
364 interface. Also fixed bug #28176 here.
366 2002-08-06 Martin Baulig <martin@gnome.org>
368 * cs-parser.jay (SimpleLookup): Removed. We need to create
369 ParameterReferences during semantic analysis so that we can do a
370 type-only search when resolving Cast, TypeOf and SizeOf.
371 (block): Pass the `current_local_parameters' to the Block's
374 * class.cs (ConstructorInitializer): Added `Parameters parameters'
375 argument to the constructor.
376 (ConstructorInitializer.Resolve): Create a temporary implicit
377 block with the parameters.
379 * ecore.cs (SimpleName.SimpleNameResolve): Resolve parameter
380 references here if we aren't doing a type-only search.
382 * statement.cs (Block): Added constructor which takes a
383 `Parameters parameters' argument.
384 (Block.Parameters): New public property.
386 * support.cs (InternalParameters.Parameters): Renamed `parameters'
387 to `Parameters' and made it public readonly.
389 2002-08-06 Martin Baulig <martin@gnome.org>
391 * ecore.cs (Expression.Warning): Made this public as well.
393 * report.cs (Report.Debug): Print the contents of collections.
395 2002-08-06 Martin Baulig <martin@gnome.org>
397 * ecore.cs (Expression.ResolveFlags): New [Flags] enum. This is
398 used to tell Resolve() which kinds of expressions it may return.
399 (Expression.Resolve): Added overloaded version of this method which
400 takes a `ResolveFlags flags' argument. This can be used to tell
401 Resolve() which kinds of expressions it may return. Reports a
403 (Expression.ResolveWithSimpleName): Removed, use Resolve() with
404 ResolveFlags.SimpleName.
405 (Expression.Error118): Added overloaded version of this method which
406 takes a `ResolveFlags flags' argument. It uses the flags to determine
407 which kinds of expressions are allowed.
409 * expression.cs (Argument.ResolveMethodGroup): New public method.
410 Resolves an argument, but allows a MethodGroup to be returned.
411 This is used when invoking a delegate.
413 * TODO: Updated a bit.
415 2002-08-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
417 Fixed compilation with csc.
419 * ecore.cs: Expression.Error made public. Is this correct? Should
420 Warning be made public too?
422 * expression.cs: use ea.Location instead of ea.loc.
423 [FIXME: Filed as bug #28607: MCS must report these errors.]
425 2002-08-06 Martin Baulig <martin@gnome.org>
427 * ecore.cs (Expression.loc): Moved the location here instead of
428 duplicating it in all derived classes.
429 (Expression.Location): New public property.
430 (Expression.Error, Expression.Warning): Made them non-static and
431 removed the location argument.
432 (Expression.Warning): Added overloaded version which takes an
433 `int level' argument.
434 (Expression.Error118): Make this non-static and removed the
435 expression and location arguments.
436 (TypeExpr): Added location argument to the constructor.
438 * expression.cs (StaticCallExpr): Added location argument to
440 (Indirection, PointerArithmetic): Likewise.
441 (CheckedExpr, UnCheckedExpr): Likewise.
442 (ArrayAccess, IndexerAccess, UserCast, ArrayPtr): Likewise.
443 (StringPtr): Likewise.
446 2002-08-05 Martin Baulig <martin@gnome.org>
448 * expression.cs (BaseAccess.DoResolve): Actually report errors.
450 * assign.cs (Assign.DoResolve): Check whether the source
451 expression is a value or variable.
453 * statement.cs (Try.Resolve): Set ec.InTry/InCatch/InFinally
454 while resolving the corresponding blocks.
456 * interface.cs (Interface.GetInterfaceTypeByName): Actually report
457 an error, don't silently return null.
459 * statement.cs (Block.AddVariable): Do the error reporting here
460 and distinguish between CS0128 and CS0136.
461 (Block.DoResolve): Report all unused labels (warning CS0164).
462 (LabeledStatement): Pass the location to the constructor.
463 (LabeledStatement.HasBeenReferenced): New property.
464 (LabeledStatement.Resolve): Set it to true here.
466 * statement.cs (Return.Emit): Return success even after reporting
467 a type mismatch error (CS0126 or CS0127), this is what csc does and
468 it avoids confusing the users with any consecutive errors.
470 2002-08-05 Martin Baulig <martin@gnome.org>
472 * enum.cs (Enum.LookupEnumValue): Catch circular definitions.
474 * const.cs (Const.LookupConstantValue): Catch circular definitions.
476 * expression.cs (MemberAccess.DoResolve): Silently return if an
477 error has already been reported.
479 * ecore.cs (Expression.MemberLookupFinal): Silently return if an
480 error has already been reported.
482 2002-08-05 Martin Baulig <martin@gnome.org>
484 * statement.cs (UsageVector): Only initialize the `parameters'
485 vector if we actually have any "out" parameters.
487 2002-08-05 Martin Baulig <martin@gnome.org>
489 * expression.cs (Binary.ResolveOperator): When combining delegates,
490 they must have the same type.
492 2002-08-05 Martin Baulig <martin@gnome.org>
494 * typemanager.cs (TypeManager.GetArgumentTypes): Don't call
495 PropertyInfo.GetIndexParameters() on dynamic types, this doesn't
496 work with the ms runtime and we also don't need it: if we're a
497 PropertyBuilder and not in the `indexer_arguments' hash, then we
498 are a property and not an indexer.
500 * class.cs (TypeContainer.AsAccessible): Use Type.IsArray,
501 Type.IsPointer and Type.IsByRef instead of Type.HasElementType
502 since the latter one doesn't work with the ms runtime.
504 2002-08-03 Martin Baulig <martin@gnome.org>
506 Fixed bugs #27998 and #22735.
508 * class.cs (Method.IsOperator): New public field.
509 (Method.CheckBase): Report CS0111 if there's already a method
510 with the same parameters in the current class. Report CS0508 when
511 attempting to change the return type of an inherited method.
512 (MethodData.Emit): Report CS0179 if a method doesn't have a body
513 and it's not marked abstract or extern.
514 (PropertyBase): New abstract base class for Property and Indexer.
515 (PropertyBase.CheckBase): Moved here from Property and made it work
517 (PropertyBase.Emit): Moved here from Property.Emit, Indexer.Emit is
518 the same so we can reuse it there.
519 (Property, Indexer): Derive from PropertyBase.
520 (MethodSignature.inheritable_property_signature_filter): New delegate
521 to find properties and indexers.
523 * decl.cs (MemberCore.CheckMethodAgainstBase): Added `string name'
524 argument and improved error reporting.
526 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): Renamed to
527 EmptyReadOnlyParameters and made it a property.
529 * typemanager.cs (TypeManager.GetArgumentTypes): Added overloaded
530 version of this method which takes a `PropertyInfo indexer'.
531 (TypeManager.RegisterIndexer): New method.
533 * class.cs: Added myself as author of this file :-)
535 2002-08-03 Gonzalo Paniagua Javier <gonzalo@ximian.com>
537 * class.cs: fixed compilation on windoze.
539 2002-08-03 Martin Baulig <martin@gnome.org>
541 * interface.cs (Interface.GetInterfaceBases): Check whether all
542 base interfaces are at least as accessible than the current one.
544 * class.cs (TypeContainer.GetClassBases): Check whether base types
545 are at least as accessible than the current type.
546 (TypeContainer.AsAccessible): Implemented and made non-static.
547 (MemberBase.CheckParameters): Report errors if the accessibility
550 * delegate.cs (Delegate.Delegate): The default visibility is
551 internal for top-level types and private for nested types.
552 (Delegate.Define): Report errors if the accessibility checks fail.
554 * enum.cs (Enum.Enum): The default visibility is internal for
555 top-level types and private for nested types.
556 (Enum.DefineType): Compute the correct visibility.
558 * modifiers.cs (Modifiers.TypeAttr): Added a version of this
559 function which takes a `bool is_toplevel' instead of a TypeContainer.
561 * typemanager.cs (TypeManager.IsBuiltinType): `void' is also a
564 2002-08-02 Martin Baulig <martin@gnome.org>
566 * expression.cs (LocalVariableReferenc): Added constructor which
567 takes additional `VariableInfo vi' and `bool is_readonly' arguments.
568 (LocalVariableReference.IsReadOnly): New property.
569 (LocalVariableReference.DoResolveLValue): Report a CS1604 if the
570 variable is readonly, use our own readonly flag to do this; you can
571 use the new constructor to get a writable reference to a read-only
574 * cs-parser.jay (foreach_statement, using_statement): Get a writable
575 reference to the local variable.

687 and resolvings from Emit to Resolve.
689 * statement.cs (For): Moved all code that does variable lookups
690 and resolvings from Emit to Resolve.
692 * statement.cs (Using): Moved all code that does variable lookups
693 and resolvings from Emit to Resolve.
695 2002-07-29 Martin Baulig <martin@gnome.org>
697 * attribute.cs (Attribute.Resolve): Explicitly catch a
698 System.NullReferenceException when creating the
699 CustromAttributeBuilder and report a different warning message.

711 is a flag which specifies that it's either ref or out.
712 (Parameter.GetParameterInfo (DeclSpace, int, out bool)): Changed
713 the out parameter to `out Parameter.Modifier mod', also set the
714 Parameter.Modifier.ISBYREF flag on it if it's either ref or out.

764 Fixes bug #24007, added test-152.cs.
766 2002-07-27 Martin Baulig <martin@gnome.org>
768 * expression.cs (Invocation.EmitArguments): When calling a varargs
769 function with only its fixed arguments, we need to pass an empty
772 2002-07-27 Martin Baulig <martin@gnome.org>
774 Mono 0.13 has been released.
776 2002-07-25 Miguel de Icaza <miguel@ximian.com>
778 * driver.cs: Rename --resource to --linkres, because that is what
779 we do currently, we dont support --resource yet.
781 * cs-tokenizer.cs: Fix test for reporting endif mismatches.
783 2002-07-25 Martin Baulig <martin@gnome.org>
785 * class.cs (MethodData): New public class. This is a `method builder'
786 class for a method or one accessor of a Property/Indexer/Event.
787 (MethodData.GetMethodFlags): Moved here from MemberBase.
788 (MethodData.ApplyAttributes): Likewise.
789 (MethodData.ApplyObsoleteAttribute): Likewise.
790 (MethodData.ApplyConditionalAttribute): Likewise.
791 (MethodData.ApplyDllImportAttribute): Likewise.
792 (MethodData.CheckAbstractAndExternal): Likewise.
793 (MethodData.Define): Formerly knows as MemberBase.DefineMethod().
794 (MethodData.Emit): Formerly known as Method.Emit().
795 (MemberBase): Moved everything which was specific to a single
796 accessor/method to MethodData.
797 (Method): Create a new MethodData and call Define() and Emit() on it.
798 (Property, Indexer, Event): Create a new MethodData objects for each
799 accessor and call Define() and Emit() on them.
801 2002-07-25 Martin Baulig <martin@gnome.org>
803 Made MethodCore derive from MemberBase to reuse the code from there.
804 MemberBase now also checks for attributes.
806 * class.cs (MethodCore): Derive from MemberBase, not MemberCore.
807 (MemberBase.GetMethodFlags): Moved here from class Method and marked
809 (MemberBase.DefineAccessor): Renamed to DefineMethod(), added
810 `CallingConventions cc' and `Attributes opt_attrs' arguments.
811 (MemberBase.ApplyAttributes): New virtual method; applies the
812 attributes to a method or accessor.
813 (MemberBase.ApplyObsoleteAttribute): New protected virtual method.
814 (MemberBase.ApplyConditionalAttribute): Likewise.
815 (MemberBase.ApplyDllImportAttribute): Likewise.
816 (MemberBase.CheckAbstractAndExternal): Likewise.

818 method, it's initialized from DoDefineParameters().
819 (MethodCore.ParameterInfo): Removed the set accessor.
820 (MethodCore.DoDefineParameters): New protected virtual method to
821 initialize ParameterTypes and ParameterInfo.
822 (Method.GetReturnType): We can now simply return the MemberType.
823 (Method.GetMethodFlags): Override the MemberBase version and add
824 the conditional flags.
825 (Method.CheckBase): Moved some code from Define() here, call
826 DoDefineParameters() here.
827 (Method.Define): Use DoDefine() and DefineMethod() from MemberBase
828 here to avoid some larger code duplication.
829 (Property.Emit, Indexer.Emit): Call CheckAbstractAndExternal() to
830 ensure that abstract and external accessors don't declare a body.
832 * attribute.cs (Attribute.GetValidPieces): Make this actually work:
833 `System.Attribute.GetCustomAttributes (attr.Type)' does a recursive
834 lookup in the attribute's parent classes, so we need to abort as soon
835 as we found the first match.
836 (Attribute.Obsolete_GetObsoleteMessage): Return the empty string if
837 the attribute has no arguments.
839 * typemanager.cs (TypeManager.AddMethod): Now takes a MemberBase instead
842 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
844 * cs-parser.jay: reverted previous patch.
846 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
848 * cs-parser.jay: fixed bug #22119.
850 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
852 * attribute.cs: fixed compilation. The error was:
853 "attribute.cs(571,17): error CS0177: The out parameter 'is_error' must
854 be assigned to before control leaves the current method."
855 [FIXME: Filed as bug #28186: MCS must report this error.]
857 2002-07-25 Martin Baulig <martin@gnome.org>
859 * attribute.cs (Attribute.Conditional_GetConditionName): New static
860 method to pull the condition name ouf of a Conditional attribute.
861 (Attribute.Obsolete_GetObsoleteMessage): New static method to pull
862 the obsolete message and error flag out of an Obsolete attribute.
864 * class.cs (Method.GetMethodFlags): New public method to get the
865 TypeManager.MethodFlags for this method.
866 (Method.ApplyConditionalAttribute, Method.ApplyObsoleteAttribute): New
868 (Method.Define): Get and apply the Obsolete and Conditional attributes;
869 if we're overriding a virtual function, set the new private variable
870 `parent_method'; call the new TypeManager.AddMethod().
872 * typemanager.cs (TypeManager.AddMethod): New static method. Stores
873 the MethodBuilder and the Method in a PtrHashtable.
874 (TypeManager.builder_to_method): Added for this purpose.
875 (TypeManager.MethodFlags): Added IsObsoleteError.
876 (TypeManager.GetMethodFlags): Added `Location loc' argument. Lookup
877 Obsolete and Conditional arguments in MethodBuilders. If we discover
878 an Obsolete attribute, emit an appropriate warning 618 / error 619 with
879 the message from the attribute.
881 2002-07-24 Martin Baulig <martin@gnome.org>
883 * cs-tokenizer.cs: Eat up trailing whitespaces and one-line comments in
884 preprocessor directives, ensure that the argument to #define/#undef is
885 exactly one identifier and that it's actually an identifier.
887 Some weeks ago I did a `#define DEBUG 1' myself and wondered why this
890 2002-07-24 Martin Baulig <martin@gnome.org>
892 * statement.cs (Foreach.ForeachHelperMethods): Added `Type element_type',
893 initialize it to TypeManager.object_type in the constructor.
894 (Foreach.GetEnumeratorFilter): Set `hm.element_type' to the return type
895 of the `hm.get_current' method if we're using the collection pattern.
896 (Foreach.EmitCollectionForeach): Use `hm.element_type' as the source type
897 for the explicit conversion to make it work when we're using the collection
898 pattern and the `Current' property has a different return type than `object'.
901 2002-07-24 Martin Baulig <martin@gnome.org>
903 * delegate.cs (Delegate.VerifyMethod): Simply return null if the method
904 does not match, but don't report any errors. This method is called in
905 order for all methods in a MethodGroupExpr until a matching method is
906 found, so we don't want to bail out if the first method doesn't match.
907 (NewDelegate.DoResolve): If none of the methods in the MethodGroupExpr
908 matches, report the 123. Fixes #28070.
910 2002-07-24 Martin Baulig <martin@gnome.org>
912 * expression.cs (ArrayAccess.EmitStoreOpcode): Moved the
913 TypeManager.TypeToCoreType() to the top of the method so the
914 following equality checks will work. Fixes #28107.
916 2002-07-24 Martin Baulig <martin@gnome.org>
918 * cfold.cs (ConstantFold.DoConstantNumericPromotions): "If either
919 operand is of type uint, and the other operand is of type sbyte,
920 short or int, the operands are converted to type long." -
921 Actually do what this comment already told us. Fixes bug #28106,
924 2002-07-24 Martin Baulig <martin@gnome.org>
926 * class.cs (MethodBase): New abstract class. This is now a base
927 class for Property, Indexer and Event to avoid some code duplication
928 in their Define() and DefineMethods() methods.
929 (MethodBase.DoDefine, MethodBase.DefineAccessor): Provide virtual
930 generic methods for Define() and DefineMethods().
931 (FieldBase): Derive from MemberBase, not MemberCore.
932 (Property): Derive from MemberBase, not MemberCore.
933 (Property.DefineMethod): Moved all the code from this method to the
934 new MethodBase.DefineAccessor(), just call it with appropriate
936 (Property.Define): Call the new Property.DoDefine(), this does some
937 sanity checks and we don't need to duplicate the code everywhere.
938 (Event): Derive from MemberBase, not MemberCore.
939 (Event.Define): Use the new MethodBase.DefineAccessor() to define the
940 accessors, this will also make them work with interface events.
941 (Indexer): Derive from MemberBase, not MemberCore.
942 (Indexer.DefineMethod): Removed, call MethodBase.DefineAccessor() insstead.
943 (Indexer.Define): Use the new MethodBase functions.
945 * interface.cs (InterfaceEvent.InterfaceEvent): Added `Location loc'
946 argument to the constructor.
947 (Interface.FindMembers): Added support for interface events.
948 (Interface.PopluateEvent): Implemented.
950 Added test-149.cs for this. This also fixes bugs #26067 and #24256.
952 2002-07-22 Miguel de Icaza <miguel@ximian.com>
954 * class.cs (TypeContainer.AddMethod): Adding methods do not use IsValid,
955 but this is required to check for a method name being the same as
956 the containing class.
960 2002-07-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
962 * interface.cs: initialize variable.
964 2002-07-23 Martin Baulig <martin@gnome.org>
966 Implemented the IndexerName attribute in interfaces.
968 * class.cs (TypeContainer.DefineIndexers): Don't set the indexer
969 name if this is an explicit interface implementation.
970 (Indexer.InterfaceIndexerName): New public variable. If we're
971 implementing an interface indexer, this is the IndexerName in that
972 interface. Otherwise, it's the IndexerName.
973 (Indexer.DefineMethod): If we're implementing interface indexer,
974 set InterfaceIndexerName. Use the new Pending.IsInterfaceIndexer
975 and Pending.ImplementIndexer methods.
976 (Indexer.Define): Also define the PropertyBuilder if we're
977 implementing an interface indexer and this is neither an explicit
978 interface implementation nor do the IndexerName match the one in
981 * pending.cs (TypeAndMethods): Added `MethodInfo [] need_proxy'.
982 If a method is defined here, then we always need to create a proxy
983 for it. This is used when implementing interface indexers.
984 (Pending.IsInterfaceIndexer): New public method.
985 (Pending.ImplementIndexer): New public method.
986 (Pending.InterfaceMethod): Added `MethodInfo need_proxy' argument.
987 This is used when implementing interface indexers to define a proxy
989 (Pending.VerifyPendingMethods): Look in the `need_proxy' array and
990 define a proxy if necessary.
992 * interface.cs (Interface.IndexerName): New public variable.
993 (Interface.PopulateIndexer): Set the IndexerName.
994 (Interface.DefineIndexers): New private method. Populate all the
995 indexers and make sure their IndexerNames match.
997 * typemanager.cs (IndexerPropertyName): Added support for interface
1000 2002-07-22 Martin Baulig <martin@gnome.org>
1002 * codegen.cs (EmitContext.HasReturnLabel): New public variable.
1003 (EmitContext.EmitTopBlock): Always mark the ReturnLabel and emit a
1004 ret if HasReturnLabel.
1005 (EmitContext.TryCatchLevel, LoopBeginTryCatchLevel): New public
1008 * statement.cs (Do.Emit, While.Emit, For.Emit, Foreach.Emit): Save
1009 and set the ec.LoopBeginTryCatchLevel.
1010 (Try.Emit): Increment the ec.TryCatchLevel while emitting the block.
1011 (Continue.Emit): If the ec.LoopBeginTryCatchLevel is smaller than
1012 the current ec.TryCatchLevel, the branch goes out of an exception
1013 block. In this case, we need to use Leave and not Br.
1015 2002-07-22 Martin Baulig <martin@gnome.org>
1017 * statement.cs (Try.Emit): Emit an explicit ret after the end of the
1018 block unless the block does not always return or it is contained in
1019 another try { ... } catch { ... } block. Fixes bug #26506.
1020 Added verify-1.cs to the test suite.
1022 2002-07-22 Martin Baulig <martin@gnome.org>
1024 * statement.cs (Switch.TableSwitchEmit): If we don't have a default,
1025 then we do not always return. Fixes bug #24985.
1027 2002-07-22 Martin Baulig <martin@gnome.org>
1029 * expression.cs (Invocation.OverloadedResolve): Do the BetterFunction()
1030 lookup on a per-class level; ie. walk up the class hierarchy until we
1031 found at least one applicable method, then choose the best among them.
1032 Fixes bug #24463 and test-29.cs.
1034 2002-07-22 Martin Baulig <martin@gnome.org>
1036 * typemanager.cs (TypeManager.ArrayContainsMethod): Don't check the
1037 return types of the methods. The return type is not part of the
1038 signature and we must not check it to make the `new' modifier work.
1039 Fixes bug #27999, also added test-147.cs.
1040 (TypeManager.TypeToCoreType): Added TypeManager.type_type.
1042 * expression.cs (Invocation.DoResolve): Call TypeManager.TypeToCoreType()
1043 on the method's return type.
1045 2002-07-21 Martin Baulig <martin@gnome.org>
1047 * assign.cs: Make this work if the rightmost source is a constant and
1048 we need to do an implicit type conversion. Also adding a few more tests
1049 to test-38.cs which should have caught this.
1051 * makefile.gnu: Disable debugging, there's already the mcs-mono2.exe
1052 target in the makefile for this. The makefile.gnu is primarily intended
1053 for end-users who don't want to debug the compiler.
1055 2002-07-21 Martin Baulig <martin@gnome.org>
1057 * assign.cs: Improved the Assign class so it can now handle embedded
1058 assignments (X = Y = Z = something). As a side-effect this'll now also
1059 consume less local variables. test-38.cs now passes with MCS, added
1060 a few new test cases to that test.
1062 2002-07-20 Martin Baulig <martin@gnome.org>
1064 * expression.cs (Binary.EmitBranchable): Emit correct unsigned branch
1065 instructions. Fixes bug #27977, also added test-146.cs.
1067 2002-07-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1069 * cs-tokenizer.cs: fixed getHex ().
1071 2002-07-19 Martin Baulig <martin@gnome.org>
1073 * expression.cs (Invocation.EmitParams): Use TypeManager.LookupType(),
1074 not Type.GetType() to lookup the array type. This is needed when
1075 we're constructing an array of a user-defined type.
1076 (ArrayAccess.EmitDynamicInitializers): Only emit the Ldelema for
1077 single-dimensional arrays, but also for single-dimensial arrays of
1080 2002-07-19 Martin Baulig <martin@gnome.org>
1082 * expression.cs (New.DoEmit): Create a new LocalTemporary each time
1083 this function is called, it's not allowed to share LocalBuilders
1086 2002-07-19 Martin Baulig <martin@gnome.org>
1088 * expression.cs (Argument.Resolve): Report an error 118 when trying
1089 to pass a type as argument.
1091 2002-07-18 Martin Baulig <martin@gnome.org>
1093 * ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
1094 Conv_R_Un for the signed `long' type.
1096 2002-07-15 Miguel de Icaza <miguel@ximian.com>
1098 * expression.cs (MemberAccess.DoResolve): Do not reuse the field
1099 `expr' for the temporary result, as that will fail if we do
1100 multiple resolves on the same expression.
1102 2002-07-05 Miguel de Icaza <miguel@ximian.com>
1104 * ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
1105 ec.TypeContainer for looking up aliases.
1107 * class.cs (TypeContainer): Remove LookupAlias from here.
1109 * decl.cs (DeclSpace); Move here.
1111 2002-07-01 Miguel de Icaza <miguel@ximian.com>
1113 * class.cs (FindMembers): Only call filter if the constructor
1114 bulider is not null.
1116 Also handle delegates in `NestedTypes' now. Now we will perform
1117 type lookups using the standard resolution process. This also
1120 * decl.cs (DeclSpace.ResolveType): New type resolution routine.
1121 This uses Expressions (the limited kind that can be parsed by the
1122 tree) instead of strings.
1124 * expression.cs (ComposedCast.ToString): Implement, used to flag
1125 errors since now we have to render expressions.
1127 (ArrayCreation): Kill FormElementType. Use ComposedCasts in
1130 * ecore.cs (SimpleName.ToString): ditto.
1132 * cs-parser.jay: Instead of using strings to assemble types, use
1133 Expressions to assemble the type (using SimpleName, ComposedCast,
1134 MemberAccess). This should fix the type lookups in declarations,
1135 because we were using a different code path for this.
1137 * statement.cs (Block.Resolve): Continue processing statements
1138 even when there is an error.
1140 2002-07-17 Miguel de Icaza <miguel@ximian.com>
1142 * class.cs (Event.Define): Also remove the `remove' method from
1143 the list of pending items.
1145 * expression.cs (ParameterReference): Use ldarg.N (0..3) to
1146 generate more compact code.
1148 2002-07-17 Martin Baulig <martin@gnome.org>
1150 * const.cs (Const.LookupConstantValue): Add support for constant
1151 `unchecked' and `checked' expressions.
1152 Also adding test case test-140.cs for this.
1154 2002-07-17 Martin Baulig <martin@gnome.org>
1156 * statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
1157 check whether mi.ReturnType implements the IEnumerator interface; the
1158 `==' and the IsAssignableFrom() will fail in this situation.
1160 2002-07-16 Ravi Pratap <ravi@ximian.com>
1162 * ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix
1165 2002-07-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1167 * expression.cs: fixed bug #27811.
1169 2002-07-14 Miguel de Icaza <miguel@ximian.com>
1171 * expression.cs (ParameterReference.AddressOf): Patch from Paolo
1172 Molaro: when we are a ref, the value already contains a pointer
1173 value, do not take the address of it.
1175 2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1176 * removed mb-parser.jay and mb-tokenizer.cs
1178 Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
1180 * expression.cs: check against the building corlib void type.
1182 Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
1184 * ecore.cs: fix for valuetype static readonly fields: when
1185 initializing them, we need their address, not the address of a copy.
1187 Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
1189 * typemanager.cs: register also enum_type in corlib.
1191 Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
1193 * class.cs: allow calling this (but not base) initializers in structs.
1195 Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
1197 * ecore.cs: make sure we compare against the building base types
1200 Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
1202 * typemanager.cs: fix TypeToCoreType() to handle void and object
1203 (corlib gets no more typerefs after this change).
1205 2002-07-12 Miguel de Icaza <miguel@ximian.com>
1207 * expression.cs (ArrayCreation.EmitArrayArguments): use
1208 Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
1210 (ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
1211 Conv_Ovf_I_Un for the array arguments. Even if C# allows longs as
1212 array indexes, the runtime actually forbids them.
1214 * ecore.cs (ExpressionToArrayArgument): Move the conversion code
1215 for array arguments here.
1217 * expression.cs (EmitLoadOpcode): System.Char is a U2, use that
1218 instead of the default for ValueTypes.
1220 (New.DoEmit): Use IsValueType instead of
1221 IsSubclassOf (value_type)
1222 (New.DoResolve): ditto.
1223 (Invocation.EmitCall): ditto.
1225 * assign.cs (Assign): ditto.
1227 * statement.cs (Unsafe): Ok, so I got the semantics wrong.
1228 Statements *are* currently doing part of their resolution during
1231 Expressions do always resolve during resolve, but statements are
1232 only required to propagate resolution to their children.
1234 2002-07-11 Miguel de Icaza <miguel@ximian.com>
1236 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
1238 (LoadAssembly): Do not add the dll if it is already specified
1240 (MainDriver): Add the System directory to the link path at the end,
1241 after all the other -L arguments.
1243 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
1244 wrong opcode for loading bytes and bools (ldelem.i1 instead of
1245 ldelem.u1) and using the opposite for sbytes.
1247 This fixes Digger, and we can finally run it.
1249 * driver.cs (UnixParseOption): Move the option parsing here.
1250 (CSCParseOption): Implement CSC-like parsing of options.
1252 We now support both modes of operation, the old Unix way, and the
1253 new CSC-like way. This should help those who wanted to make cross
1256 The only thing broken is that /r:, /reference: and /lib: are not
1257 implemented, because I want to make those have the same semantics
1258 as the CSC compiler has, and kill once and for all the confussion
1259 around this. Will be doing this tomorrow.
1261 * statement.cs (Unsafe.Resolve): The state is checked during
1262 resolve, not emit, so we have to set the flags for IsUnsfe here.
1264 2002-07-10 Miguel de Icaza <miguel@ximian.com>
1266 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
1267 not catch the Error_ObjectRefRequired in SimpleName (as it is
1268 possible to have a class/instance variable name that later gets
1269 deambiguated), we have to check this here.
1271 2002-07-10 Ravi Pratap <ravi@ximian.com>
1273 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
1274 make static and put into Expression.
1276 (Event.Define): Register the private field of the event with the
1277 TypeManager so that GetFieldFromEvent can get at it.
1279 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
1280 keep track of the private field associated with an event which
1283 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
1286 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
1288 2002-07-10 Miguel de Icaza <miguel@ximian.com>
1290 * expression.cs (Binary.EmitBranchable): this routine emits the
1291 Binary expression in a branchable context. This basically means:
1292 we need to branch somewhere, not just get the value on the stack.
1294 This works together with Statement.EmitBoolExpression.
1296 * statement.cs (Statement.EmitBoolExpression): Use
1299 2002-07-09 Miguel de Icaza <miguel@ximian.com>
1301 * statement.cs (For): Reduce the number of jumps in loops.
1303 (For): Implement loop inversion for the For statement.
1305 (Break): We can be breaking out of a Try/Catch controlled section
1306 (foreach might have an implicit try/catch clause), so we need to
1307 use Leave instead of Br.
1309 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
1310 now). If the instace expression supports IMemoryLocation, we use
1311 the AddressOf method from the IMemoryLocation to extract the
1312 address instead of emitting the instance.
1314 This showed up with `This', as we were emitting the instance
1315 always (Emit) instead of the Address of This. Particularly
1316 interesting when This is a value type, as we dont want the Emit
1317 effect (which was to load the object).
1319 2002-07-08 Miguel de Icaza <miguel@ximian.com>
1321 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
1323 * statement.cs (Checked): Set the CheckedState during the resolve
1324 process too, as the ConvCast operations track the checked state on
1325 the resolve process, and not emit.
1327 * cs-parser.jay (namespace_member_declaration): Flag that we have
1328 found a declaration when we do. This is used to flag error 1529
1330 * driver.cs: Report ok when we display the help only.
1332 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
1334 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
1336 2002-07-04 Miguel de Icaza <miguel@ximian.com>
1338 * cs-tokenizer.cs (define): We also have to track locally the
1339 defines. AllDefines is just used for the Conditional Attribute,
1340 but we also need the local defines for the current source code.
1342 2002-07-03 Miguel de Icaza <miguel@ximian.com>
1344 * statement.cs (While, For, Do): These loops can exit through a
1345 Break statement, use this information to tell whether the
1346 statement is the last piece of code.
1348 (Break): Flag that we break.
1350 * codegen.cs (EmitContexts): New `Breaks' state variable.
1352 2002-07-03 Martin Baulig <martin@gnome.org>
1354 * class.cs (TypeContainer.MethodModifiersValid): Allow override
1355 modifiers in method declarations in structs. Otherwise, you won't
1356 be able to override things like Object.Equals().
1358 2002-07-02 Miguel de Icaza <miguel@ximian.com>
1360 * class.cs (Method, Property, Indexer): Do not allow the public
1361 modifier to be used in explicit interface implementations.
1363 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
1364 override modifiers in method declarations in structs
1366 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
1368 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
1369 integer or real overflow, report an error
1371 2002-07-02 Martin Baulig <martin@gnome.org>
1373 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
1374 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
1375 to tell the runtime about our newly created System.Object and
1376 System.ValueType types.
1378 2002-07-02 Miguel de Icaza <miguel@ximian.com>
1380 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
1381 struct instead of Ldarg/Starg.
1383 2002-07-02 Martin Baulig <martin@gnome.org>
1385 * expression.cs (Indirection.Indirection): Call
1386 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
1388 2002-07-02 Martin Baulig <martin@gnome.org>
1390 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
1391 ValueType, call TypeManager.TypeToCoreType() on it.
1392 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
1393 the OpCodes.Newarr argument.
1395 2002-07-02 Martin Baulig <martin@gnome.org>
1397 * expression.cs (Invocation.EmitCall): When compiling corlib,
1398 replace all calls to the system's System.Array type to calls to
1399 the newly created one.
1401 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
1402 System.Array methods.
1403 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
1404 from the system's System.Array type which must be replaced.
1406 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
1408 * typemanager.cs: load unverifiable_code_ctor so we can build
1409 corlib using the correct type. Avoid using GetTypeCode() with
1411 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
1412 TypeManager.object_type to allow building corlib.
1414 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
1416 * ecore.cs: handle System.Enum separately in LoadFromPtr().
1418 2002-07-01 Martin Baulig <martin@gnome.org>
1420 * class.cs: Make the last change actually work, we need to check
1421 whether `ifaces != null' to avoid a crash.
1423 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
1425 * class.cs: when we build structs without fields that implement
1426 interfaces, we need to add the interfaces separately, since there is
1427 no API to both set the size and add the interfaces at type creation
1430 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
1432 * expression.cs: the dimension arguments to the array constructors
1433 need to be converted if they are a long.
1435 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
1437 * class.cs: don't emit ldarg.0 if there is no parent constructor
1438 (fixes showstopper for corlib).
1440 2002-06-29 Martin Baulig <martin@gnome.org>
1442 MCS now compiles corlib on GNU/Linux :-)
1444 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
1445 ie. check for MethodImplOptions.InternalCall.
1447 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
1448 and TypeManager.attribute_type are null, so we must explicitly check
1449 whether parent is not null to find out whether it's an attribute type.
1450 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
1451 and SetBuilder, not only if the property is neither abstract nor external.
1452 This is necessary to set the MethodImplOptions on the accessor methods.
1453 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
1454 SetBuilder, see Property.Emit().
1456 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
1457 populate "System.Object", "System.ValueType" and "System.Attribute" since
1458 they've already been populated from BootCorlib_PopulateCoreTypes().
1460 2002-06-29 Martin Baulig <martin@gnome.org>
1462 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
1463 is the NullLiteral, we also need to make sure that target_type is not
1466 2002-06-29 Martin Baulig <martin@gnome.org>
1468 * rootcontext.cs (RootContext.ResolveCore): We must initialize
1469 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
1470 before calling BootstrapCorlib_ResolveDelegate ().
1472 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1474 * statement.cs: fixed build-breaker. All tests passed ok.
1476 2002-06-27 Martin Baulig <martin@gnome.org>
1478 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
1479 for System.Decimal when compiling corlib.
1481 2002-06-27 Martin Baulig <martin@gnome.org>
1483 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
1484 switch blocks which contain nothing but a default clause.
1486 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
1488 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
1490 2002-06-27 Martin Baulig <martin@gnome.org>
1492 * ecore.cs (PropertyExpr.PropertyExpr): Call
1493 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
1495 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
1496 is already a TypeBuilder.
1498 2002-06-27 Martin Baulig <martin@gnome.org>
1500 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
1501 `target_type == TypeManager.array_type', not IsAssignableFrom() in
1502 the "from an array-type to System.Array" case. This makes it work
1503 when compiling corlib.
1505 2002-06-27 Martin Baulig <martin@gnome.org>
1507 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
1508 non-static PropertyExpr, set its InstanceExpression. This makes
1509 the `ICollection.Count' property work in System/Array.cs.
1511 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
1513 * driver.cs: Made error handling more consistent. Errors now
1514 tracked by Report class, so many methods which used to return int
1515 now return void. Main() now prints success/failure and
1516 errors/warnings message.
1518 Renamed '--probe' compiler argument to '--expect-error'. Removed
1519 the magic number return values (123 and 124). Now, if the
1520 expected error occurs, the compiler exits with success (exit value
1521 0). If the compilation completes without seeing that particular
1522 error, the compiler exits with failure (exit value 1). The
1523 makefile in mcs/errors has been changed to handle the new behaviour.
1525 * report.cs: Made 'expected error' number a property and renamed
1526 it from 'Probe' to 'ExpectedError'.
1528 * genericparser.cs: Removed error handling support, since it is
1529 now all done by Report class.
1531 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
1532 class, so parse() no longer returns an int.
1534 * namespace.cs: Use Report.Error instead of GenericParser.error
1536 2002-06-22 Miguel de Icaza <miguel@ximian.com>
1538 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
1539 TypeContainer.AddOperator): At the front of the list put the
1540 explicit implementations, so they get resolved/defined first.
1542 2002-06-21 Miguel de Icaza <miguel@ximian.com>
1544 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
1545 interface type is implemented by this TypeContainer. Used during
1546 explicit interface implementation.
1548 (Property.Define, Indexer.Define, Method.Define): Validate that
1549 the given interface in the explicit implementation is one of the
1550 base classes for the containing type.
1552 Also if we are explicitly implementing an interface, but there is
1553 no match in the pending implementation table, report an error.
1555 (Property.Define): Only define the property if we are
1556 not explicitly implementing a property from an interface. Use the
1557 correct name also for those properties (the same CSC uses,
1558 although that is really not needed).
1560 (Property.Emit): Do not emit attributes for explicitly implemented
1561 properties, as there is no TypeBuilder.
1563 (Indexer.Emit): ditto.
1565 Hiding then means that we do not really *implement* a pending
1566 implementation, which makes code fail.
1568 2002-06-22 Martin Baulig <martin@gnome.org>
1570 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
1571 the return value of Object.GetType(). [FIXME: we need to do this whenever
1572 we get a type back from the reflection library].
1574 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
1576 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
1578 2002-06-20 Miguel de Icaza <miguel@ximian.com>
1580 * attribute.cs: Return null if we can not look up the type.
1582 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
1583 the interface types found.
1585 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
1586 interface types found.
1588 * typemanager.cs (GetInterfaces): Make this routine returns alll
1589 the interfaces and work around the lame differences between
1590 System.Type and System.Reflection.Emit.TypeBuilder in the results
1591 result for GetInterfaces.
1593 (ExpandInterfaces): Given an array of interface types, expand and
1594 eliminate repeated ocurrences of an interface. This expands in
1595 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
1598 2002-06-21 Martin Baulig <martin@gnome.org>
1600 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
1603 2002-06-21 Martin Baulig <martin@gnome.org>
1605 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
1606 and called with one of the core types, return the corresponding typebuilder for
1609 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
1612 2002-06-21 Martin Baulig <martin@gnome.org>
1614 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
1615 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
1616 (Expression.ConvertReferenceExplicit): Likewise.
1618 * expression.cs (ElementAccess.DoResolve): Likewise.
1619 (ElementAccess.DoResolveLValue): Likewise.
1621 2002-06-10 Martin Baulig <martin@gnome.org>
1623 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
1624 add the "value" parameter to the parameter list.
1626 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
1629 2002-06-19 Miguel de Icaza <miguel@ximian.com>
1631 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
1632 the argument to an int, uint, long or ulong, per the spec. Also
1633 catch negative constants in array creation.
1635 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
1637 * class.cs: do not allow the same interface to appear twice in
1638 the definition list.
1640 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
1642 * ecore.cs: don't use ldlen with System.Array.
1644 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
1646 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
1648 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
1650 * modifiers.cs: produce correct field attributes for protected
1651 internal. Easy fix so miguel can work on ther harder stuff:-)
1653 2002-06-18 Miguel de Icaza <miguel@ximian.com>
1655 * pending.cs: New file. Move the code from class.cs here.
1656 Support clearning the pending flag for all methods (when not doing
1657 explicit interface implementation).
1659 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
1661 * rootcontext.cs: added a couple more types needed to bootstrap.
1663 2002-06-17 Miguel de Icaza <miguel@ximian.com>
1665 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
1666 constructor in the type, instead of any constructor in the type
1667 hierarchy. Thanks to Paolo for finding this bug (it showed up as
1668 a bug in the Mono runtime when applying the params attribute).
1670 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1671 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
1673 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
1675 * expression.cs (Unary.ResolveOperator): Use TypeManager
1676 to resolve the type.
1678 2002-06-13 Ravi Pratap <ravi@ximian.com>
1680 * cs-parser.jay (enum_member_declaration): Pass in the attributes
1683 * enum.cs (AddEnumMember): Add support to store the attributes associated
1684 with each member too.
1686 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
1687 field builders too - this takes care of the enum member case.
1689 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
1691 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
1692 address-of operator on both value types and pointers.
1694 2002-06-10 Martin Baulig <martin@gnome.org>
1696 * interface.cs (Interface.PopulateIndexer): Add the indexer's
1697 PropertyBuilder to the `property_builders' list.
1699 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
1700 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
1701 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
1702 find any indexers which are inherited from an interface.
1704 2002-06-09 Martin Baulig <martin@gnome.org>
1706 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
1707 the same type as the constant if necessary. There's also a test-130.cs
1710 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
1712 * typemanager.cs (TypeManager.ChangeType): Previously known as
1713 Enum.ChangeEnumType().
1715 2002-06-09 Martin Baulig <martin@gnome.org>
1717 * expression.cs (Cast.TryReduce): Added support for consts.
1719 2002-06-08 Ravi Pratap <ravi@ximian.com>
1721 * class.cs (Accessor): Hold attributes information so we can pass
1724 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
1725 Modify to pass in attributes attached to the methods.
1727 (add_accessor_declaration, remove_accessor_declaration): Ditto.
1729 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
1730 to handle the Accessor kind :-)
1732 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
1734 2002-06-08 Martin Baulig <martin@gnome.org>
1736 * expression.cs (Unary.TryReduceNegative): Added support for
1739 2002-06-08 Martin Baulig <martin@gnome.org>
1741 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
1742 name can't be found in the `defined_names' - the caller will do a
1743 MemberLookup in this case and thus find methods in System.Enum
1744 such as Enum.IsDefined().
1746 2002-06-08 Martin Baulig <martin@gnome.org>
1748 * enum.cs (Enum.ChangeEnumType): This is a custom version of
1749 Convert.ChangeType() which works with TypeBuilder created types.
1750 (Enum.LookupEnumValue, Enum.Define): Use it here.
1752 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
1753 `TypeBuilder.BaseType != null' check.
1754 (TypeContainer.FindMembers): Only lookup parent members if we
1755 actually have a parent.
1756 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
1757 (ConstructorInitializer.Resolve): Likewise.
1759 * interface.cs (Interface.FindMembers): Added
1760 `TypeBuilder.BaseType != null' check.
1762 * rootcontext.cs (RootContext.ResolveCore): Added
1763 "System.Runtime.CompilerServices.IndexerNameAttribute" to
1764 classes_second_stage.
1766 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
1767 debug_type and trace_type when compiling with --nostdlib.
1769 2002-06-07 Martin Baulig <martin@gnome.org>
1771 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
1772 (AddField): Set it to true when adding a non-static field.
1773 (DefineType): Use `have_nonstatic_fields' to find out whether we
1774 have non-static fields, not `Fields != null'.
1776 2002-06-02 Miguel de Icaza <miguel@ximian.com>
1778 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
1779 dereferencing a null on the static-field code path)
1781 2002-05-30 Martin Baulig <martin@gnome.org>
1783 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
1784 to take command line arguments. Use reflection to call the new
1785 custom `Initialize' function on the symbol writer and pass it the
1786 command line arguments.
1788 * driver.cs (--debug-args): New command line argument to pass command
1789 line arguments to the symbol writer.
1791 2002-05-28 Miguel de Icaza <miguel@ximian.com>
1793 * assign.cs (DoResolve): Forgot to do the implicit conversion to
1794 the target type for indexers and properties. Thanks to Joe for
1797 2002-05-27 Miguel de Icaza <miguel@ximian.com>
1799 * typemanager.cs (MethodFlags): returns the method flags
1800 (Obsolete/ShouldIgnore) that control warning emission and whether
1801 the invocation should be made, or ignored.
1803 * expression.cs (Invocation.Emit): Remove previous hack, we should
1804 not do this on matching a base type, we should do this based on an attribute
1806 Only emit calls to System.Diagnostics.Debug and
1807 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
1808 on the command line.
1810 * rootcontext.cs: Global settings for tracing and debugging.
1812 * cs-tokenizer.cs (define): New utility function to track
1813 defines. Set the global settings for TRACE and DEBUG if found.
1815 2002-05-25 Ravi Pratap <ravi@ximian.com>
1817 * interface.cs (Populate*): Pass in the TypeContainer as well as
1818 the DeclSpace as parameters so that we can create EmitContexts and
1819 then use that to apply attributes etc.
1821 (PopulateMethod, PopulateEvent, PopulateProperty)
1822 (PopulateIndexer): Apply attributes everywhere.
1824 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
1827 (ApplyAttributes): Update accordingly.
1829 We now apply interface attributes for all members too.
1831 2002-05-26 Miguel de Icaza <miguel@ximian.com>
1833 * class.cs (Indexer.Define); Correctly check if we are explicit
1834 implementation (instead of checking the Name for a ".", we
1835 directly look up if the InterfaceType was specified).
1837 Delay the creation of the PropertyBuilder.
1839 Only create the PropertyBuilder if we are not an explicit
1840 interface implementation. This means that explicit interface
1841 implementation members do not participate in regular function
1842 lookups, and hence fixes another major ambiguity problem in
1843 overload resolution (that was the visible effect).
1845 (DefineMethod): Return whether we are doing an interface
1848 * typemanager.cs: Temporary hack until we get attributes in
1849 interfaces (Ravi is working on that) and we get IndexerName
1850 support in interfaces.
1852 * interface.cs: Register the indexers as properties.
1854 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
1855 warning, I have verified that this is a bug in the .NET runtime
1856 (JavaScript suffers of the same problem).
1858 * typemanager.cs (MemberLookup): When looking up members for
1859 interfaces, the parent of an interface is the implicit
1860 System.Object (so we succeed in searches of Object methods in an
1861 interface method invocation. Example: IEnumerable x; x.ToString
1864 2002-05-25 Miguel de Icaza <miguel@ximian.com>
1866 * class.cs (Event): Events should also register if they do
1867 implement the methods that an interface requires.
1869 * typemanager.cs (MemberLookup); use the new GetInterfaces
1872 (GetInterfaces): The code used to lookup interfaces for a type is
1873 used in more than one place, factor it here.
1875 * driver.cs: Track the errors at the bottom of the file, we kept
1878 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
1879 instance if the method we are calling is static!
1881 2002-05-24 Miguel de Icaza <miguel@ximian.com>
1883 * attribute.cs (ApplyAttributes): Make this function filter out
1884 the IndexerName attribute (as that attribute in reality is never
1885 applied) and return the string constant for the IndexerName
1888 * class.cs (TypeContainer.Emit): Validate that all the indexers
1889 have the same IndexerName attribute, and if so, set the
1890 DefaultName attribute on the class.
1892 * typemanager.cs: The return value might contain other stuff (not
1893 only methods). For instance, consider a method with an "Item"
1894 property and an Item method.
1896 * class.cs: If there is a problem with the parameter types,
1899 2002-05-24 Ravi Pratap <ravi@ximian.com>
1901 * ecore.cs (ImplicitConversionExists): Wrapper function which also
1902 looks at user defined conversion after making a call to
1903 StandardConversionExists - we need this for overload resolution.
1905 * expression.cs : Update accordingly the various method calls.
1907 This fixes 2 bugs filed against implicit user defined conversions
1909 2002-05-22 Miguel de Icaza <miguel@ximian.com>
1911 * statement.cs: Track the result of the assignment.
1913 2002-05-21 Miguel de Icaza <miguel@ximian.com>
1915 * expression.cs (MemberAccess): Improved error reporting for
1916 inaccessible members.
1918 2002-05-22 Martin Baulig <martin@gnome.org>
1920 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
1921 itself with debugging support.
1923 2002-05-22 Martin Baulig <martin@gnome.org>
1925 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
1926 Removed, this isn't needed anymore.
1928 2002-05-20 Martin Baulig <martin@gnome.org>
1930 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
1931 be underlying type for an enum.
1933 2002-05-20 Miguel de Icaza <miguel@ximian.com>
1935 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
1936 that splits out the loading of just the core types.
1938 * rootcontext.cs (ResolveCore): Split the struct resolution in
1939 two, so we can load the enumeration underlying types before any
1942 * expression.cs (Is): Bandaid until we fix properly Switch (see
1943 bug #24985 for details).
1945 * typemanager.cs (ImplementsInterface): The hashtable will contain
1946 a null if there are no interfaces implemented.
1948 2002-05-18 Miguel de Icaza <miguel@ximian.com>
1950 * cs-parser.jay (indexer_declarator): It is fine to have array
1953 2002-05-17 Miguel de Icaza <miguel@ximian.com>
1955 * typemanager.cs: (RegisterBuilder): New function used to register
1956 TypeBuilders that implement interfaces. Since
1957 TypeBuilder.GetInterfaces (as usual) does not work with lame
1959 (AddUserType): register interfaces.
1961 (ImplementsInterface): Use the builder_to_ifaces hash if we are
1962 dealing with TypeBuilder. Also, arrays are showing up as
1963 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
1964 methods can not be invoked on them!
1966 * ecore.cs (ExplicitReferenceConversionExists): Made public.
1967 (ImplicitReferenceConversionExists): Split out from
1968 StandardConversionExists.
1970 * expression.cs (As): We were only implementing one of the three
1971 cases for the as operator. We now implement them all.
1972 (Is): Implement the various other cases for Is as well.
1974 * typemanager.cs (CACHE): New define used to control if we want or
1975 not the FindMembers cache. Seems to have a negative impact on
1976 performance currently
1978 (MemberLookup): Nested types have full acess to
1979 enclosing type members
1981 Remove code that coped with instance/static returns for events, we
1982 now catch this in RealFindMembers.
1984 (RealFindMembers): only perform static lookup if the instance
1985 lookup did not return a type or an event.
1987 2002-05-17 Miguel de Icaza <miguel@ximian.com>
1989 * assign.cs (CompoundAssign): We pass more semantic information
1990 now to Compound Assignments than we did before: now we have all
1991 the information at hand, and now we resolve the target *before* we
1992 do the expression expansion, which allows the "CacheValue" method
1993 to have the effect we intended (before, a [x] += 1 would generate
1994 two differen ArrayAccess expressions from the ElementAccess,
1995 during the resolution process).
1997 (CompoundAssign.DoResolve): Resolve target and original_source here.
1999 2002-05-16 Miguel de Icaza <miguel@ximian.com>
2001 * expression.cs (ArrayAccess): dropped debugging information.
2003 * typemanager.cs: Small bug fix: I was always returning i_members,
2004 instead of one of i_members or s_members (depending on which had
2007 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
2008 method is invoked before any code generation takes place, and it
2009 is a mechanism to inform that the expression will be invoked more
2010 than once, and that the method should use temporary values to
2011 avoid having side effects
2013 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
2015 * ecore.cs (Expression.CacheTemporaries): Provide empty default
2018 * expression.cs (Indirection, ArrayAccess): Add support for
2019 CacheTemporaries in these two bad boys.
2021 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
2023 (StoreFromPtr): Handle stobj as well.
2025 * expression.cs (UnaryMutator): Share more code.
2027 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
2028 down: I was not tracking the Filter function as well, which
2029 was affecting the results of the cache.
2031 2002-05-15 Miguel de Icaza <miguel@ximian.com>
2033 * attribute.cs: Remove the hack to handle the CharSet property on
2036 2002-05-14 Miguel de Icaza <miguel@ximian.com>
2038 * attribute.cs (DoResolve): More uglyness, we now only try to
2039 resolve the attribute partially, to extract the CharSet
2040 information (only if we are a StructLayout attribute). Otherwise
2042 (GetExtraTypeInfo): Add some code to conditionally kill in the
2043 future this. I am more and more convinced that the .NET
2044 framework has special code to handle the attribute setting on
2047 * expression.cs (IsParamsMethodApplicable): Revert my previous
2048 foreach change here, it was wrong.
2050 2002-05-13 Miguel de Icaza <miguel@ximian.com>
2052 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
2053 (pp_expr): do not abort on unknown input, just return.
2054 (eval): abort if there are pending chars.
2056 * attribute.cs (Attribute.Resolve): Positional parameters are
2057 optional. Deal with that case.
2059 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
2060 the Ansi/Unicode/Auto information for the type.
2062 (TypeContainer.DefineType): instantiate the EmitContext here, as
2063 we will be using it during the type definition (to resolve
2064 attributes) and during the emit phase.
2066 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
2067 to pull type information out of the attributes
2069 (Attribute.Resolve): track the constructor builder, and allow for
2070 multiple invocations (structs and classes will use this).
2072 * ecore.cs (MemberLookupFinal): new version with all the
2073 parameters customizable.
2075 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
2076 constructors. Return if the result value is null (as the error
2077 would have been flagged already by MemberLookupFinal)
2079 Do not allow instances of abstract classes or interfaces to be
2082 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
2083 We have to compare the assembly property here when dealing with
2084 FamANDAssem and Assembly access modifiers, because we might be
2085 creating an assembly from *modules* (that means that we are not
2086 getting TypeBuilders for types defined in other modules that are
2087 part of this assembly).
2089 (Method.Emit): If the method is marked abstract and has a body,
2092 (TypeContainer.DefineMembers): If both the defined member and the
2093 parent name match are methods, then do not emit any warnings: let
2094 the Method.Define routine take care of flagging warnings. But if
2095 there is a mismatch (method overrides something else, or method is
2096 overriwritten by something, then emit warning).
2098 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
2099 set to null, this means `do not check for the return type on the
2102 (Method.Define): set the return type for the method signature to
2103 null, so that we get methods with the same name and parameters and
2104 different return types. This is used to flag warning 114 (you are
2105 hiding a method, and you probably want to use the new/override
2108 * typemanager.cs (MemberLookup): Implemented proper access
2109 control, closing a long standing set of bug reports. The problem
2110 was that the Framework only has two bits: Public and NonPublic,
2111 and NonPublic includes private and protected methods, but we need
2112 to enforce the FamANDAssem, FamOrAssem and Family.
2114 2002-05-11 Miguel de Icaza <miguel@ximian.com>
2116 * statement.cs (GotoCase): Return true: Ammounts to giving up
2117 knowledge on whether we return or not, and letting the other case
2118 be responsible for it.
2120 2002-05-10 Miguel de Icaza <miguel@ximian.com>
2122 * driver.cs: Do not load directories for each file processed, only
2123 do it if there is a pattern.
2125 * ecore.cs: Report readonly assigns here as well, as we might have
2126 been resolved only by MemberAccess.
2128 (SimpleName.SimpleNameResolve): Also be useful for LValue
2129 resolution. We need this to propagate assign to local readonly variables
2131 * typemanager.cs: Use a ptrhashtable for the criteria, because we
2132 do not want to reuse potential criteria memory.
2134 * class.cs (MyEventBuilder): Set reflected_type;
2136 * ecore.cs (Constantify): Added support for constifying bools.
2138 (RootContext.LookupType): Added a cache for values looked up in
2139 the declaration space.
2141 * typemanager.cs (FindMembers): Now is a front-end to
2142 RealFindMembers, and provides a two-level hashtable-based cache to
2145 15% performance improvement: from 22.5 to 19.2 seconds.
2147 * expression.cs (IsParamsMethodApplicable): use foreach.
2148 (Invocation.DoResolve): ditto.
2149 (New.DoResolve): ditto.
2150 (ArrayCreation.DoResolve): ditto.
2152 * ecore.cs (FindMostEncompassingType): use foreach.
2154 * delegate.cs (NewDelegate.DoResolve): Use foreach
2156 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
2157 (RemoveMethods): use foreach.
2159 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
2160 nested foreach statements instead of for, and also break out of
2161 the inner loop once a match is found.
2163 (Invocation.OverloadResolve): Use foreach, simplify the code.
2165 2002-05-08 Miguel de Icaza <miguel@ximian.com>
2167 * cfold.cs (BinaryFold): During an enumeration evaluation context,
2168 we actually unwrap the expression to allow for extra information
2171 * expression.cs: Use Shr_Un on unsigned operations.
2173 2002-05-08 Ravi Pratap <ravi@ximian.com>
2175 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
2176 applicable operators was not being considered correctly. This closes
2177 the bug Miguel reported.
2179 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
2181 * attribute.cs: check that the type derives from System.Attribute
2182 and report the correct error in that case (moved the duplicate code to
2183 its own method, too).
2185 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
2187 * attribute.cs: lookup attribute type name as the spec says: first the
2188 bare attribute name and then name + "Attribute" (nant compiles with
2189 mcs after this fix).
2191 2002-05-07 Miguel de Icaza <miguel@ximian.com>
2193 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
2194 Because of the way we parse things, we should try to see if a
2195 UIntConstant can fit in an integer.
2197 2002-05-07 Ravi Pratap <ravi@ximian.com>
2199 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
2200 when we are in an explicit context.
2202 (ConvertReferenceExplicit): When converting from Iface type S to Class
2203 T make sure the rules are implemented as an OR.
2205 * parameter.cs (ParameterType): Make it a property for now although the
2206 purpose really isn't anything immediate.
2208 * expression.cs (Is*Applicable): Do better checking on the parameter type
2209 of a ref/out parameter. The ones from the system assemblies are already
2210 marked with the correct type so we don't need to do any correction.
2212 * ecore.cs (StandardConversionExists): Conversion from Interface types to
2213 the object type is standard too so include that.
2215 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2217 * ecore.cs (StandardConversionExists): Augment with missing code:
2218 deal with IntConstant, LongConstants and Enumerations.
2220 * assign.cs: Report the error, instead of failing silently
2222 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
2223 typecontainer that they are declared, because the
2224 typecontainer/namespace will have the list of using clauses that
2227 Assembly Attributes were escaping the normal registration
2230 (EmitCode): Apply attributes within an EmitContext that represents
2231 the container they were declared on.
2233 * cs-parser.jay: Track bases for structs. How did I get this wrong?
2235 2002-05-06 Ravi Pratap <ravi@ximian.com>
2237 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
2238 Revamp completely - make much cleaner as we now operate only
2241 (FindMostSpecificSource, FindMostSpecificTarget): New methods
2242 to implement the logic detailed in the spec more correctly.
2244 (UserDefinedConversion): Update accordingly.
2246 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2248 * statement.cs: Return flow analysis information up.
2250 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
2253 (token): Do not consume an extra character before calling
2256 2002-05-06 Piers Haken <piersh@friskit.com>
2258 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
2260 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2262 * class.cs (Constructor.Emit): Set the IsStatic flag in the
2263 EmitContext during the instance constructor initializer
2264 resolution, to stop access to instance variables.
2266 This is mandated by the spec, last paragraph of the `constructor
2267 initializers' section.
2269 2002-05-05 Miguel de Icaza <miguel@ximian.com>
2271 * cs-parser.jay, class.cs (Accessor): new class used to represent
2272 an accessor (get or set). In the past we used `null' to represent
2273 a missing accessor. But this is ambiguous because there was no
2274 way to tell in abstract indexers/properties if one of them was
2277 Now there is a way of addressing that.
2279 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
2280 instead of FindMembers.
2282 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
2283 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
2285 * attribute.cs: Treat indexers and properties as the same in terms
2286 of applying attributes
2288 * ecore.cs (FindMostEncompassedType): Use statically initialized
2289 EmptyExpressions()s like we do elsewhere to avoid creating useless
2290 objects (and we take this out of the tight loop).
2292 (GetConversionOperators): Move the code to extract the actual
2293 operators to a separate routine to clean things up.
2295 2002-05-04 Miguel de Icaza <miguel@ximian.com>
2297 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
2298 events are always registered FieldBuilders.
2300 * class.cs (FieldBase): New class shared by Fields
2302 * delegate.cs: If we are a toplevel delegate, use our full name.
2303 If we are a nested delegate, then only use our tail name.
2305 2002-05-02 Ravi Pratap <ravi@ximian.com>
2307 * expression.cs (IsApplicable): Ensure that we add the "&" to
2308 ref/out types before comparing it with the type of the argument.
2310 (IsParamsMethodApplicable): Ditto.
2312 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
2315 * delegate.cs : Handle the case when we have more than one applicable
2316 method. Flag an error only when we finish checking all.
2318 2002-05-02 Miguel de Icaza <miguel@ximian.com>
2320 * expression.cs: Add support for boolean static initializers.
2322 2002-05-01 Miguel de Icaza <miguel@ximian.com>
2324 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
2326 * parameter.cs (ComputeParameterTypes,
2327 ComputeAndDefineParameterTypes): Better error handling: now we
2328 clear the `types' cache if we fail during any of the type lookups.
2329 We also return the status code correctly to our caller
2331 * delegate.cs: If we fail to define a delegate, abort the extra
2334 * expression.cs (Binary.ResolveOperator): for
2335 operator==(object,object) and operator !=(object, object) we also
2336 have to verify that there is an implicit conversion from one to
2339 (ArrayAccess.DoResolve): Array Access can operate on
2342 2002-04-30 Miguel de Icaza <miguel@ximian.com>
2344 * assign.cs (CompoundAssign): A new class used as a "flag" that
2345 the assignment actually is happening as part of a compound
2346 assignment operator.
2348 During compound assignment, a few new rules exist to enable things
2355 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
2356 to the type of x) if y is implicitly convertible to the type of x,
2357 and the operator is a builtin operator and the return type of the
2358 operator is explicitly convertible to the type of x.
2360 * rootcontext.cs: Reset warning level to 2. 4 catches various
2361 "interesting" features in mcs, we must clean this up at some
2362 point, but currently am trying to kill other bugs ;-)
2364 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
2365 in container classes as well.
2367 * expression.cs (Binary.ResolveOperator): Handle string case
2368 before anything else (as operator overloading does emit an error
2369 before doing anything else).
2371 This code could go away when we move to a table driven model, but
2372 i could not come up with a good plan last night.
2374 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
2376 * typemanager.cs (CSharpName): reimplementation using regex.
2377 * class.cs: added null check for fields in Emit
2378 * rootcontext.cs: set warninglevel to 4
2380 2002-04-29 Miguel de Icaza <miguel@ximian.com>
2382 * typemanager.cs (CSharpName): reimplemented with Lupus
2385 2002-04-28 Miguel de Icaza <miguel@ximian.com>
2387 * statement.cs (If): correclty implement Resolve, because we were
2388 not catching sem errors in there. The same process is needed
2390 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
2393 (Statement.Warning_DeadCodeFound): Factorize code.
2394 (While): Report dead code here too.
2396 (Statement): Added Resolve virtual method to allow
2397 for resolution split from the emit code.
2399 2002-04-26 Miguel de Icaza <miguel@ximian.com>
2401 * statement.cs (EmitBoolExpression): No longer try to resolve the
2403 (MakeBoolean): New utility function that resolve, implicitly
2404 converts to boolean and tags the expression.
2407 (If, Do): Implement dead code elimination.
2408 (While): Implement loop inversion
2410 (Do, While, For, If): Resolve the expression prior to calling our
2413 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
2416 - added method Report28 (warning: program has more than one entry point)
2417 - added method IsEntryPoint, implements paragraph 10.1 of the spec
2418 - modified method Method.Define, the part at the end of the method
2420 * rootcontext.cs: added static public Location EntryPointLocation;
2422 * ../errors/cs0028.cs : Add test case for the above warning.
2425 - modified method CSharpName to allow arrays of primitive type to
2426 be printed nicely (e.g. instead of System.Int32[][] it now prints
2428 - added method CSharpSignature: returns the signature of a method
2429 in string format to be used in reporting errors, warnings, etc.
2431 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
2434 2002-04-26 Ravi Pratap <ravi@ximian.com>
2436 * delegate.cs (Define): Fix extremely silly bug where I was
2437 setting the type of the 'object' parameter of the BeginInvoke
2438 method to System.IAsyncResult instead of System.Object ;-)
2440 2002-04-26 Miguel de Icaza <miguel@ximian.com>
2442 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
2445 (Constructor.Emit): return if we fail to initialize the
2446 constructor. Another door closed!
2448 * expression.cs (New.DoResolve): Improve error message (from -6 to
2449 1501). Use DeclaredOnly lookup to find the exact constructor.
2451 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
2452 loop. This is useful.
2454 * cs-parser.jay: Adjust the default parameters so that destructors
2455 have the proper signature.
2457 2002-04-26 Martin Baulig <martin@gnome.org>
2459 * driver.cs (LoadAssembly): If `assembly' contains any characters
2460 which are only valid in path names and not in assembly names
2461 (currently slash, backslash and point), use Assembly.LoadFrom ()
2462 instead of Assembly.Load () on the `assembly' (before iteration
2463 over the link_paths).
2465 2002-04-26 Martin Baulig <martin@gnome.org>
2467 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
2469 2002-04-25 Miguel de Icaza <miguel@ximian.com>
2471 * class.cs (Property): use the new typemanager.MemberLookup
2473 (TypeContainer.MemberLookup): Implement using the
2474 TypeManager.MemberLookup now.
2476 * typemanager.cs: Make MemberLookup a function of the TypeManager,
2477 and return MemberInfos, so that these can be used without an
2478 EmitContext (what we had before).
2480 2002-04-24 Miguel de Icaza <miguel@ximian.com>
2482 * expression.cs: Fix the case where the argument to params if the
2483 type of the params. I omitted handling this before. Fixed
2485 2002-04-22 Miguel de Icaza <miguel@ximian.com>
2487 * driver.cs: Call BootCorlib_PopulateCoreType
2489 * class.cs (Property.CheckBase): Check for properties only, not
2492 * interface.cs: Temporary hack: try/catch around the
2493 CustomAttributeBuilder, because I am getting an exception that I
2496 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
2497 types whose definitions are required to be there (attributes are
2498 defined before standard types).
2500 Compute definitions as we boot the various types, as they are used
2501 immediately (value_type class will need object_type, but if we do
2502 not initialize object_type, we will pass a null, which will let
2503 the runtime pick the System.Object from the existing corlib, which
2504 is not what we want).
2506 2002-04-22 Patrik Torstensson <totte@labs2.com>
2508 * cs-tokenizer.cs: fixed a number of trim() issues.
2510 2002-04-22 Ravi Pratap <ravi@ximian.com>
2512 * expression.cs (Argument.Type): Ensure that we return the correct
2513 type when we have out or ref parameters [in which case we
2516 2002-04-22 Miguel de Icaza <miguel@ximian.com>
2518 * class.cs (Property, Indexer): Allow extern modifier in there.
2520 * typemanager.cs (InitBaseTypes): Initializes object_type and
2521 value_type, since those will be used early on during the bootstrap
2522 process to compile corlib.
2524 (InitCoreTypes): Move code from here to InitBaseTypes.
2526 2002-04-21 Miguel de Icaza <miguel@ximian.com>
2528 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
2529 single-dimension arrays as using the ldlen opcode.
2531 Daniel Lewis discovered this optimization.
2533 * typemanager.cs: Add signature for System.Array::get_Length
2535 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2537 * statement.cs: report the error when the foreach does not apply to an
2538 array nor a collection.
2540 2002-04-19 Miguel de Icaza <miguel@ximian.com>
2542 * expression.cs: Add implicit conversions to the operator ~.
2544 * constant.cs (DecimalConstant.Emit): Emit decimal value.
2546 * typemanager.cs: Locate the decimal constructor.
2548 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2550 * attribute.cs: use the new property of TypeOf.
2551 * expression.cs: added 'get' property around typearg.
2553 These changes fix a build breaker reported by NickD. Is this the
2554 correct way to fix? If not, please, revert my changes and make it
2557 2002-04-17 Miguel de Icaza <miguel@ximian.com>
2559 * attribute.cs: Add support for typeof in attribute invocations.
2560 I am not sure that this is right though.
2562 2002-04-14 Duncan Mak <duncan@ximian.com>
2564 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
2565 Binary.Operator.Division case.
2567 2002-04-13 Ravi Pratap <ravi@ximian.com>
2569 * class.cs (DefineType): Ensure that we do a proper check on
2570 attribute types and also register it with the TypeManager.
2572 (TypeContainer.Targets): The default for attribute types is
2573 AttributeTargets.All.
2575 * attribute.cs (ApplyAttributes): Registering the attribute type
2576 is done elsewhere, not when we discover we have a Usage attribute.
2578 2002-04-12 Ravi Pratap <ravi@ximian.com>
2580 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
2581 and get rid of is_delegate parameter.
2583 * everywhere : update.
2585 2002-04-12 Ravi Pratap <ravi@ximian.com>
2587 * cs-parser.jay (compilation_unit): Revamp completely to use
2588 some new ideas that I got from Rhys' grammar to solve the problems
2589 with assembly level attributes.
2591 (outer_declaration): New grammar production.
2593 (attribute_sections): Add.
2595 (opt_attributes): Base on attribute_sections
2597 (namespace_declaration): Allow opt_attributes to tackle the case
2598 when we have assembly level attributes - we are clever in this
2601 * attribute.cs (ApplyAttributes): Do not worry about assembly
2602 attributes in the non-global context.
2604 * rootcontext.cs (AddGlobalAttributes): Go back to using this
2605 instead of SetGlobalAttributes.
2607 * class.cs, rootcontext.cs : Ensure we define and generate
2608 attribute types before anything else.
2610 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
2611 and flag the new error -20 for the case when the attribute type
2612 does not have valid targets specified. csc does not catch this.
2614 * ../errors/errors.txt : update for error # -20
2616 2002-04-11 Ravi Pratap <ravi@ximian.com>
2618 * support.cs (InternalParameters.ParameterModifier): Do some null
2619 checking and return sane values.
2621 * class.cs (Method.Define): If we are a PInvoke method, ensure
2622 that we are static and extern. Report error # 601
2624 * ../errors/cs0601.cs : Add test case for the above error.
2626 2002-04-07 Ravi Pratap <ravi@ximian.com>
2628 * rootcontext.cs (attribute_types): We need to keep type of
2629 all attribute types separately and emit code for them first.
2631 (RegisterAttribute) : Implement.
2633 * class.cs (DefineType): Check if the current Type is a custom
2634 attribute type and register it accordingly.
2636 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
2637 adding the first attribute twice and rename to
2639 (SetGlobalAttributes): this.
2641 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
2644 * attribute.cs (ApplyAttributes): Take an additional argument telling us
2645 if we are processing global arguments. Hmm, I am unsure of this.
2647 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2649 * expression.cs: added static array of strings to avoid calling
2650 Enum.ToString () for Operator in Binary. Significant recover of
2653 2002-04-10 Miguel de Icaza <miguel@ximian.com>
2655 * class.cs (FindMembers): Allow the Builders of the various
2656 members to be null. If they are skip them. This only happens
2657 during the PInvoke declaration.
2659 2002-04-09 Miguel de Icaza <miguel@ximian.com>
2661 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
2662 failure, so we do not keep going afterwards.
2664 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
2665 wanted to pass `false' as the `is_delegate' argument. If this is
2666 the case, why not use delegate_type == null to mean `is_delegate =
2667 false' and anything else as is_delegate = true.
2669 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
2671 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
2672 code for the section, not the beginning of the tests.
2674 2002-04-08 Miguel de Icaza <miguel@ximian.com>
2676 * cfold.cs: Handle operator + (Enum x, Underlying x)
2678 * expression.cs (Binary): same. Warn about errors where we have
2679 Enum/Enum in operator + as well.
2681 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
2684 - added support for switch(bool)
2685 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
2686 - add TableSwitchEmit() to handle table-based switch statements
2688 2002-04-05 Ravi Pratap <ravi@ximian.com>
2690 * expression.cs (Invocation.OverloadResolve): Factor out code which
2691 does parameter compatibility checking with arguments so that we can
2692 re-use the code even from Delegate.VerifyApplicability
2694 (VerifyArgumentsCompat): Move above code here.
2696 * delegate.cs (VerifyApplicability): Get rid of duplicate code
2697 and instead make a call to the above method.
2699 2002-03-31 Ravi Pratap <ravi@ximian.com>
2701 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
2702 We use it to keep track of classes which are attribute types.
2704 2002-04-02 Miguel de Icaza <miguel@ximian.com>
2706 * delegate.cs (Delegate.Define): Correctly define the types in the
2707 presence of fixed and array parameters.
2709 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
2712 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
2713 include NonPublic after the first iteration.
2715 * class.cs (Indexer.CheckBase): Only check if both parents are
2718 * cs-parser.jay (accessor_body): If empty, set to null.
2720 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
2721 same code path here to resolve constants names that we did have in
2722 MemberAccess.DoResolve. There is too much code duplicated here.
2724 2002-04-01 Miguel de Icaza <miguel@ximian.com>
2726 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
2728 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
2731 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
2732 tokens, numbers and strings.
2734 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
2737 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
2738 asyncronous parameters and the regular parameters.
2740 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
2741 specify the target directory.
2743 * expression.cs: (This.DoResolve): Simplify
2744 (As.Emit): Optimize, do not generate IsInst if the expression is
2745 always of the given type.
2747 (Is.DoResolve): Bug fix, we were reporting both always/never for
2750 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
2751 creating too many unnecessary arrays.
2753 2002-03-31 Miguel de Icaza <miguel@ximian.com>
2755 * class.cs (EmitFieldInitializer): Use Assign expression to assign
2756 fields instead of rolling our own initializer. Takes care of all
2757 implicit conversions, and drops unnecessary static checks/argument.
2759 2002-03-31 Dick Porter <dick@ximian.com>
2761 * driver.cs: use the GetDirectories() return values properly, and
2762 use "/" as path separator.
2764 2002-03-30 Miguel de Icaza <miguel@ximian.com>
2766 * expression.cs (Unary): Optimize - - expr into expr.
2767 (Binary): Optimize a + (-b) into a -b.
2769 * codegen.cs (CodeGen): Made all methods static.
2771 2002-03-29 Miguel de Icaza <miguel@ximian.com>
2775 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
2776 TypeBuilder property.
2778 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
2781 * tree.cs: Removed the various RecordXXXX, and replaced with a
2782 single RecordDecl. Removed all the accessor methods, and just
2783 left a single access point Type
2785 * enum.cs: Rename DefineEnum to DefineType.
2787 * decl.cs: New abstract method `DefineType' used to unify the
2788 Defines for Enumerations, Interfaces, TypeContainers and
2791 (FindType): Moved LookupInterfaceOrClass here. Moved the
2792 LookupBaseClasses method that used to live in class.cs and
2793 interface.cs here, and renamed to FindType.
2795 * delegate.cs: Implement DefineType. Take advantage of the
2796 refactored pattern for locating the parent builder without taking
2797 the parent_builder argument (which we know does not work if we are
2798 nested, and triggering a toplevel definition).
2800 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2802 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
2803 accessibility of a member has changed during override and report
2806 * class.cs (Method.Define, Property.Define): Only complain on
2807 overrides if the method is private, any other accessibility is
2808 fine (and since we just checked the permission is the same, we are
2811 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
2812 and elif are processed always. The other pre-processing
2813 directives are only processed if we are "taking" the path
2815 2002-03-29 Martin Baulig <martin@gnome.org>
2817 * class.cs (Method.Emit): Only emit symbolic debugging info if the
2818 current location is not Null.
2820 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
2821 a separate method so we can profile it.
2823 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
2824 `span.Seconds' are just seconds, but no minutes or hours.
2825 (MainDriver): Profile the CodeGen.SaveSymbols calls.
2827 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2829 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
2830 Remove the gratuitous set of Final:
2832 // If an interface implementation, then we can set Final.
2833 if (((flags & MethodAttributes.Abstract) == 0) &&
2834 implementing.DeclaringType.IsInterface)
2835 flags |= MethodAttributes.Final;
2837 I do not know what I was smoking when I used that.
2840 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
2841 step into fixing the name resolution issues for delegates and
2842 unifying the toplevel name resolution.
2844 2002-03-28 Martin Baulig <martin@gnome.org>
2846 * class.cs (Method.Emit): If we have a symbol writer, call its
2847 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
2848 tell it about the current method.
2850 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
2851 writer that we're going to emit the first byte of IL code for a new
2852 statement (a new source line).
2853 (EmitContext.EmitTopBlock): If we have a symbol writer, call
2854 EmitContext.Mark() before emitting any code.
2856 * location.cs (SymbolDocument): Return null when we're Null.
2858 * statement.cs (Statement): Moved the `Location loc' variable here.
2859 (Statement.EmitBoolExpression): If we have a symbol writer, call
2860 ec.Mark() before emitting any code to tell it that we're at the
2861 beginning of a new statement.
2862 (StatementExpression): Added `Location' argument to the constructor.
2863 (Block): Added public readonly variable `StartLocation' and public
2864 variable `EndLocation'. The latter is to be set using SetEndLocation().
2865 (Block): Added constructor which takes a start and end location.
2866 (Block.SetEndLocation): New method. This sets the end location.
2867 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
2868 local variables we create.
2869 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
2870 each statement and do also mark the begin and end of the block.
2872 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
2873 tell it the current lexer.Location, use Location.Null for the end of the
2875 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
2876 current block, set its end location using SetEndLocation().
2877 (statement_expression): StatementExpression constructor now takes the
2878 lexer.Location as additional argument.
2879 (for_statement, declare_local_variables): Likewise.
2880 (declare_local_variables): When creating a new implicit block, use the
2881 new Block constructor and pass it the lexer.Location.
2883 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2885 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
2886 members also on the parent interfaces recursively.
2888 2002-03-27 Miguel de Icaza <miguel@ximian.com>
2890 * report.cs: Use new formats, since Gonzalo finished the missing
2893 * expression.cs (Binary.ResolveOperator): added missing operator|
2894 operator& and operator^ for bool/bool.
2896 * cs-parser.jay: CheckDef now takes a Location argument that is
2897 used to report errors more precisly (instead of reporting the end
2898 of a definition, we try to track something which is a lot closer
2899 to the source of the problem).
2901 * cs-tokenizer.cs: Track global token use, so we can properly flag
2902 the use of #define/#undef after the first token has been seen.
2904 Also, rename the reportXXXX to Error_DescriptiveName
2906 * decl.cs (DeclSpace.IsTopLevel): Move property here from
2907 TypeContainer, so that Enum and Interface can use this too.
2909 * class.cs (TypeContainer.LookupInterfaceOrClass,
2910 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
2911 `builder' argument. Typically this was used to pass the parent
2912 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
2915 The problem is that a nested class could trigger the definition of
2916 a toplevel class, and the builder would be obviously wrong in that
2919 So we drop this argument, and we compute dynamically the
2920 TypeBuilder/ModuleBuilder (the correct information was available
2921 to us anyways from DeclSpace.Parent)
2923 * interface.cs (Interface.DefineInterface): Drop builder
2924 parameter cleanup like class.cs
2926 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
2929 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
2932 (Try.Emit): Propagate the returns value from the statement.
2934 (Return.Emit): Even if we are leavning
2936 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
2938 * modifiers.cs: Fix the computation of MethodAttributes flags.
2940 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
2942 * driver.cs: allow compilation of files that start with '/'.
2943 Add a default case when checking the argument of --target.
2945 2002-03-25 Miguel de Icaza <miguel@ximian.com>
2947 * interface.cs: Implement the same search algorithm for types in
2950 * delegate.cs: Do not allow multiple definition.
2952 * Recovered ChangeLog that got accidentally amputated
2954 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
2956 * rootcontext.cs: Load manually enum to allow core classes to
2957 contain enumerations.
2959 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
2960 Update to new static methods in TypeManager.
2962 * typemanager.cs (GetMethod, GetConstructor): Use our
2963 implementation of FindMembers to find the members, since during
2964 corlib compilation, the types are TypeBuilders and GetMethod and
2965 GetConstructor do not work.
2967 Make all methods in TypeManager static.
2969 (InitCodeHelpers): Split the functionality from
2970 the InitCodeTypes function.
2972 * driver.cs: Call InitCodeHelpers after we have populated the
2975 * cs-parser.jay (delegate_declaration): we did not used to compute
2976 the delegate name correctly for void delegates.
2978 2002-03-24 Miguel de Icaza <miguel@ximian.com>
2980 * rootcontext.cs (RootContext): Init the interface_resolve_order
2981 and type_container_resolve_order always.
2983 (ResolveCore, BootstrapCorlib_ResolveClass,
2984 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
2985 compiler when compiling with --nostdlib
2987 * class.cs (TypeContainer.DefineType): Check that our parent is
2988 not null. This test is most important when we are bootstraping
2991 * codegen.cs: Split out the symbol writing code.
2993 2002-03-25 Martin Baulig <martin@gnome.org>
2995 * driver.cs (-g): Made -g an alias for --debug.
2997 2002-03-24 Martin Baulig <martin@gnome.org>
2999 * codegen.cs (SymbolWriter): New public variable. Returns the
3000 current symbol writer.
3001 (CodeGen): Added `bool want_debugging_support' argument to the
3002 constructor. If true, tell the ModuleBuild that we want debugging
3003 support and ask it for the ISymbolWriter.
3004 (Save): If we have a symbol writer, call it's Close() method after
3005 saving the assembly.
3007 * driver.c (--debug): New command line argument to create a
3008 debugger information file.
3010 * location.cs (SymbolDocument): New public property. Returns an
3011 ISymbolDocumentWriter object for the current source file or null
3012 if we don't have a symbol writer.
3014 2002-03-21 Miguel de Icaza <miguel@ximian.com>
3016 * driver.cs (LoadAssembly): Correctly return when all the paths
3017 have been tried and not before.
3019 * statement.cs (Switch.Emit): return the actual coverage for this
3020 statement (returns/not-returns)
3022 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
3023 switch of the statement if we are the last switch section. That
3024 kills two problems: try/catch problems (we used to emit an empty
3025 nop at the end) and switch statements where all branches would
3028 2002-03-19 Miguel de Icaza <miguel@ximian.com>
3030 * driver.cs: Add default assemblies (the equivalent to the
3031 Microsoft CSC.RSP file)
3033 * cs-tokenizer.cs: When updating `cols and setting it to zero,
3034 also update tokens_seen and set it to false.
3036 * driver.cs: Implement --recurse for Mike.
3038 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
3039 correctly splitting out the paths.
3041 2002-03-18 Miguel de Icaza <miguel@ximian.com>
3043 * interface.cs (Interface.PopulateProperty): Instead of using
3044 `parent' as the declaration space for the set parameters, use
3047 * support.cs (InternalParameters): InternalParameters constructor
3048 takes a DeclSpace instead of a TypeContainer.
3050 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
3051 types are being initialized, load the address of it before calling
3054 (New): Provide a mechanism to disable the generation of local
3055 value type temporaries when the caller will be providing us with
3056 an address to store it.
3058 (ArrayCreation.EmitDynamicInitializers): Use it.
3060 2002-03-17 Miguel de Icaza <miguel@ximian.com>
3062 * expression.cs (Invocation.EmitArguments): Only probe for array
3063 property if there is more than one argument. Sorry about that.
3065 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
3068 * class.cs (Method.LabelParameters): Fix incorrect code path that
3069 prevented the `ParamArrayAttribute' from being applied to the
3072 2002-03-16 Miguel de Icaza <miguel@ximian.com>
3074 * support.cs (ReflectionParameters): Correctly compute whether the
3075 last argument is a params array. Fixes the problem with
3078 * typemanager.cs: Make the assemblies array always be non-null
3079 (empty, but non-null)
3081 * tree.cs (RecordDecl): New function that abstracts the recording
3082 of names. This reports error 101, and provides a pointer to the
3083 previous declaration. Fixes a crash in the compiler.
3085 * cs-parser.jay (constructor_declaration): Update to new grammar,
3086 and provide a constructor_body that can be empty.
3088 2002-03-15 Miguel de Icaza <miguel@ximian.com>
3090 * driver.cs: Add support for --resources.
3092 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
3093 Make all types for the various array helper methods be integer.
3095 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
3096 CheckState to ConvCast.
3098 (ConvCast): Now it takes a `checked' state argument, to avoid
3099 depending on the emit context for the conversion, and just using
3100 the resolve time setting.
3102 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
3103 instead of Invocation.EmitArguments. We do not emit the original
3104 arguments, instead we emit those which have been converted to
3105 unsigned int expressions.
3107 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
3109 * codegen.cs: ditto.
3111 * expression.cs (LocalVariableReference): Drop the use of the
3112 Store function that depended on the variable index.
3114 * statement.cs (VariableInfo): Drop the `Idx' property from this
3115 class, as this is not taking into account the indexes for
3116 temporaries tat we generate during the execution, getting the
3119 * class.cs: First emit class initializers, then call the parent
3122 * expression.cs (Binary): Fix opcode emision.
3123 (UnaryMutator.EmitCode): Support checked code generation
3125 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
3126 matches for events for both the Static and Instance scans,
3127 pointing to the same element. Fix that.
3129 2002-03-14 Miguel de Icaza <miguel@ximian.com>
3131 * rootcontext.cs (ResolveTree): Always set the
3132 interface_resolve_order, because nested interfaces will be calling
3135 * class.cs (GetInterfaceOrClass): Track the same resolution
3136 process used by TypeManager.LookupType. This fixes the nested
3137 type lookups in class declarations (separate path from
3140 (TypeContainer.DefineType): Also define nested interfaces.
3141 (TypeContainer.RegisterOrder): New public function used to
3142 register the order in which child interfaces need to be closed.
3144 Nested interfaces need to be closed after their parents have been
3147 * interface.cs (InterfaceAttr): Put all the logic for computing
3148 the interface attribute here.
3150 (DefineInterface): Register our interface order with the
3151 RootContext or with the TypeContainer depending on the case.
3153 2002-03-12 Miguel de Icaza <miguel@ximian.com>
3155 * cs-parser.jay: rework foreach statement to work with the new
3156 changes to the policy on SimpleNames.
3158 * report.cs: support Stacktrace on warnings as well.
3160 * makefile: drop --unsafe and /unsafe from the compile.
3162 2002-03-13 Ravi Pratap <ravi@ximian.com>
3164 * ecore.cs (StandardConversionExists): Modify to take an Expression
3165 as the first parameter. Ensure we do null -> reference type conversion
3168 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
3169 temporary Expression objects.
3171 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
3173 * interface.cs: workaround bug in method overloading resolution
3174 (there is already a bugzilla bug for it).
3176 2002-03-12 Miguel de Icaza <miguel@ximian.com>
3178 We could also solve this problem by having a separate path for
3179 performing type lookups, instead of DoResolve, we could have a
3180 ResolveType entry point, and only participating pieces of the
3181 production (simplename, deref, array) would implement this.
3183 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
3184 signal SimpleName to only resolve type names and not attempt to
3185 resolve anything else.
3187 * expression.cs (Cast): Set the flag.
3189 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
3191 * class.cs: Only report 108 if there is no `new' modifier.
3193 * cs-parser.jay: rework foreach statement to work with the new
3194 changes to the policy on SimpleNames.
3196 * report.cs: support Stacktrace on warnings as well.
3198 * makefile: drop --unsafe and /unsafe from the compile.
3200 2002-03-11 Miguel de Icaza <miguel@ximian.com>
3202 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
3203 lookups here, instead of doing that at parse time. This means
3204 that our grammar will not introduce `LocalVariableReferences' as
3205 expressions at this point. That solves the problem of code like
3213 This is only half the fix. The full fix requires parameters to
3214 also be handled in this way.
3216 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
3217 makes the use more obvious of the DeclSpace. The
3218 ec.TypeContainer.TypeBuilder is now only used to pull the
3221 My theory is that I can get rid of the TypeBuilder completely from
3222 the EmitContext, and have typecasts where it is used (from
3223 DeclSpace to where it matters).
3225 The only pending problem is that the code that implements Aliases
3226 is on TypeContainer, and probably should go in DeclSpace.
3228 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
3229 lookups here, instead of doing that at parse time. This means
3230 that our grammar will not introduce `LocalVariableReferences' as
3231 expressions at this point. That solves the problem of code like
3239 This is only half the fix. The full fix requires parameters to
3240 also be handled in this way.
3242 * class.cs (Property.DefineMethod): When implementing an interface
3243 method, set newslot, when implementing an abstract method, do not
3244 set the flag (before we tried never setting it, or always setting
3245 it, which is the difference).
3246 (Indexer.DefineMethod): same.
3247 (Method.DefineMethod): same.
3249 * ecore.cs: Only set the status used flag if we get back a Field.
3251 * attribute.cs: Temporary hack, so Paolo can keep working.
3253 2002-03-08 Ravi Pratap <ravi@ximian.com>
3255 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
3256 the unmanaged type in the case we have a MarshalAs attribute.
3258 (Resolve): Handle the case when we are parsing the special MarshalAs
3259 attribute [we need to store the unmanaged type to use later]
3261 * typemanager.cs (marshal_as_attr_type): Built in type for the
3262 MarshalAs Attribute.
3264 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
3265 on parameters and accordingly set the marshalling info.
3267 2002-03-09 Miguel de Icaza <miguel@ximian.com>
3269 * class.cs: Optimizing slightly by removing redundant code after
3270 we switched to the `NoTypes' return value.
3271 (Property.DefineMethod): use NoTypes here too.
3273 This fixes the bug I introduced in my last batch of changes.
3275 2002-03-05 Ravi Pratap <ravi@ximian.com>
3277 * tree.cs (RecordEnum): Add. We now keep track of enums too.
3279 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
3280 Enums since those are types too.
3282 * cs-parser.jay (enum_declaration): Record enums as we parse them.
3284 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
3285 thanks to a call during the lookup process.
3287 2002-03-07 Miguel de Icaza <miguel@ximian.com>
3289 * statement.cs (Foreach): Lots of work to accomodate a particular
3290 kind of foreach statement that I had not kept in mind. It is
3291 possible to have foreachs on classes that provide a GetEnumerator
3292 method that return objects that implement the "pattern" for using
3293 a foreach, there is no need to support GetEnumerator
3296 This is needed to compile nant.
3298 * decl.cs: Only report 114 if the member is not `Finalize' and if
3299 the warning level is at least 2.
3301 * class.cs: Moved the compare function from Method to
3304 (MethodSignature.InheritableMemberSignatureCompare): Add new
3305 filter function that is used to extract inheritable methods from a
3308 (Method.Define): Use the new `inheritable_method_signature_filter'
3311 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
3314 2002-03-06 Miguel de Icaza <miguel@ximian.com>
3316 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
3318 * cs-parser.jay: Add opt_semicolon to the interface declaration.
3320 * expression.cs: Pass location information to
3321 ConvertImplicitStandard.
3323 * class.cs: Added debugging code to track return values from
3326 2002-03-05 Miguel de Icaza <miguel@ximian.com>
3328 * expression.cs (Is.DoResolve): If either side of the `is' is an
3329 interface, do not flag the warning.
3331 * ecore.cs (ImplicitReferenceConversion): We need a separate test
3334 * report.cs: Allow for --fatal to be used with --probe.
3336 * typemanager.cs (NoTypes): Move the definition for the empty Type
3339 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
3341 (TypeContainer.DefineProxy): New function used to proxy to parent
3342 implementations when implementing interfaces.
3343 (TypeContainer.ParentImplements): used to lookup if our parent
3344 implements a public function that is required by an interface.
3345 (TypeContainer.VerifyPendingMethods): Hook this up.
3347 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
3348 `modules' and `assemblies' arraylists into arrays. We only grow
3349 these are the very early start up of the program, so this improves
3350 the speedof LookupType (nicely measured).
3352 * expression.cs (MakeByteBlob): Replaced unsafe code with
3353 BitConverter, as suggested by Paolo.
3355 * cfold.cs (ConstantFold.Binary): Special case: perform constant
3356 folding of string concatenation, but if either side is a string,
3357 and the other is not, then return null, and let the runtime use
3358 the concatenation on the string plus the object (using
3361 2002-03-04 Miguel de Icaza <miguel@ximian.com>
3363 Constant Folding has been implemented now.
3365 * expression.cs (Unary.Reduce): Do not throw an exception, catch
3366 the error instead on types that are not supported in one's
3369 * constant.cs (Constant and all children): New set of functions to
3370 perform implict and explicit conversions.
3372 * ecore.cs (EnumConstant): Implement the new functions to perform
3373 conversion by proxying to the child expression.
3375 * codegen.cs: (ConstantCheckState): Constant evaluation has its
3376 own separate setting that can not be turned off from the command
3377 line using --unchecked or --checked and is only controlled using
3378 the checked/unchecked statements and expressions. This setting is
3379 used by the constant folder to flag errors.
3381 * expression.cs (CheckedExpr, UncheckedExpr): Set the
3382 ConstantCheckState as well.
3384 During Resolve, they also have to flag the state, because the
3385 constant folder runs completely in the Resolve phase.
3387 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
3390 2002-03-01 Miguel de Icaza <miguel@ximian.com>
3392 * cfold.cs: New file, this file contains the constant folder.
3394 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
3395 argument to track whether we are using the resulting address to
3396 load or store a value and provide better error messages.
3398 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
3399 new AddressOf arguments.
3401 * statement.cs (Foreach.EmitCollectionForeach): Update
3403 * expression.cs (Argument.Emit): Call AddressOf with proper
3404 arguments to track usage.
3406 (New.DoEmit): Call AddressOf with new arguments.
3408 (Unary.Emit): Adjust AddressOf call.
3410 2002-03-01 Ravi Pratap <ravi@ximian.com>
3412 * cs-parser.jay (member_access): Change the case for pre-defined types
3413 to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
3416 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
3419 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
3420 essentially like methods and apply attributes like MethodImplOptions to them too.
3422 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
3425 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
3426 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
3429 * Update code everywhere accordingly.
3431 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
3433 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
3435 2002-02-28 Ravi Pratap <ravi@ximian.com>
3437 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
3438 try performing lookups against those instead of jumping straight into using
3439 the 'using' clauses.
3441 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
3443 (LookupType): Perform lookups in implicit parents too.
3445 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
3446 sequence as RootContext.LookupType.
3448 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
3449 the various cases of namespace lookups into this method.
3451 2002-03-01 Miguel de Icaza <miguel@ximian.com>
3453 * cs-parser.jay: Add support for [Attribute ()] (empty arguments
3454 in positional arguments)
3456 * class.cs (Operator): Update the AllowedModifiers to contain
3459 * cs-parser.jay: Update operator declaration to allow for the
3460 operator body to be empty.
3462 * cs-tokenizer.cs: Added '\u' unicode support in strings and hex
3465 2002-02-27 Miguel de Icaza <miguel@ximian.com>
3467 * class.cs (Method.Emit): Label parameters.
3469 * driver.cs: Return 1 or 0 as the program exit code.
3471 2002-02-26 Miguel de Icaza <miguel@ximian.com>
3473 * expression.cs: Special case the `null' object when trying to
3474 auto-compute the type, as anything can be explicitly converted to
3477 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
3478 spotting this Paolo.
3480 (Expression.ImplicitNumericConversion): Perform comparissions of
3481 the type using the underlying type in the case of an enumeration
3482 rather than using the enumeration type for the compare.
3484 Cope with the underlying == type case, which is not possible to
3487 (Expression.ConvertNumericExplicit): Perform comparissions of
3488 the type using the underlying type in the case of an enumeration
3489 rather than using the enumeration type for the compare.
3491 * driver.cs: If the user does not supply an extension, assume .exe
3493 * cs-parser.jay (if_statement): Rewrote so that we can track the
3494 location for the if statement.
3496 * expression.cs (Binary.ConstantFold): Only concat strings when
3497 the operation is "+", not everything ;-)
3499 * statement.cs (Statement.EmitBoolExpression): Take a location
3501 (If, While, Do): Track location.
3503 * expression.cs (Binary.ResolveOperator): In the object + string
3504 case, I was missing a call to ConvertImplicit
3506 2002-02-25 Ravi Pratap <ravi@ximian.com>
3508 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
3509 Location arguments. Ensure we use RootContext.LookupType to do our work
3510 and not try to do a direct Type.GetType and ModuleBuilder.GetType
3512 * interface.cs (PopulateMethod): Handle the type of the parameter being
3515 * expression.cs (Invocation.BetterFunction): Handle the case when we
3516 have a params method with no fixed arguments and a call is made with no
3519 2002-02-25 Miguel de Icaza <miguel@ximian.com>

3522 the verbatim-string-literal
3524 * support.cs (InternalParameters.ParameterModifier): handle null
3526 (InternalParameters.ParameterType): ditto.
3528 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
3529 duplicating the name of the variable parameter.
3530 (GetParameterByName): Fix bug where we were not looking up array
3531 paramters if they were the only present (thanks Paolo!).
3532 (GetParameterInfo): We only have an empty set of types if both
3533 fixed and array are set to null.
3534 (GetParameterInfo-idx): Handle FixedParameter == null
3536 * cs-parser.jay: Handle the case where there is no catch
3537 statements (missing null test).
3539 2002-02-22 Miguel de Icaza <miguel@ximian.com>
3541 * driver.cs (MainDriver): Be conservative on our command line
3544 Catch DirectoryNotFoundException when calling GetFiles.
3546 (SplitPathAndPattern): Used to split the input specification into
3547 a path and a pattern that we can feed to Directory.GetFiles.
3549 2002-02-21 Miguel de Icaza <miguel@ximian.com>
3551 * statement.cs (Fixed): Implement the last case of the Fixed
3552 statement (string handling).
3554 * expression.cs (StringPtr): New class used to return a char * to
3555 a string; Used by the Fixed statement.
3557 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
3559 * expression.cs (Binary.ResolveOperator): Remove redundant
3560 MemberLookup pn parent type.
3561 Optimize union call, we do not need a union if the types are the same.
3562 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
3565 Specialize the use of MemberLookup everywhere, instead of using
3566 the default settings.
3568 (StackAlloc): Implement stackalloc keyword.
3570 * cs-parser.jay: Add rule to parse stackalloc.
3572 * driver.cs: Handle /h, /help, /?
3574 * expression.cs (MakeByteBlob): Removed the hacks we had in place
3575 before we supported unsafe code.
3577 * makefile: add --unsafe to the self compilation of mcs.
3579 2002-02-20 Miguel de Icaza <miguel@ximian.com>
3581 * expression.cs (PointerArithmetic): New class that is used to
3582 perform pointer arithmetic.
3583 (Binary.Resolve): Handle pointer arithmetic
3584 Handle pointer comparission.
3585 (ArrayPtr): Utility expression class that is used to take the
3586 address of an array.
3588 (ElementAccess): Implement array access for pointers
3590 * statement.cs (Fixed): Implement fixed statement for arrays, we
3591 are missing one more case before we are done.
3593 * expression.cs (Indirection): Implement EmitAssign and set the
3594 ExprClass to Variable. This allows pointer dereferences to be
3595 treated as variables, and to have values assigned to them.
3597 * ecore.cs (Expression.StoreFromPtr): New utility function to
3598 store values dereferencing.
3600 2002-02-20 Ravi Pratap <ravi@ximian.com>
3602 * expression.cs (Binary.ResolveOperator): Ensure that we are
3603 not trying to operate on a void type - this fixes the reported
3606 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
3607 the parent implementation is sealed.
3609 * ../errors/cs0239.cs : Add.
3611 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
3613 * typemanager.cs (unverifiable_code_type): Corresponds to
3614 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
3615 which have unsafe code in them.
3617 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
3620 2002-02-19 Miguel de Icaza <miguel@ximian.com>
3622 * cs-tokenizer.cs: Add support for @"litreal strings"
3624 Make tokenizer accept pre-processor directives
3625 on any column (remove the old C-like limitation).
3627 * rootcontext.cs (EmitCode): Emit any global attributes.
3628 (AddGlobalAttributes): Used to keep track of assembly attributes.
3630 * attribute.cs (ApplyAttributes): Support AssemblyAttributes.
3632 * cs-parser.jay: Add support for global attributes.
3634 2002-02-17 Miguel de Icaza <miguel@ximian.com>
3636 * expression.cs (Indirection): New helper class. Unary will
3637 create Indirection classes to be able to implement the
3638 IMemoryLocation interface on it.
3640 2002-02-16 Miguel de Icaza <miguel@ximian.com>
3642 * cs-parser.jay (fixed_statement): reference the right statement.
3644 * statement.cs (Fixed.Emit): Finish implementing the fixed
3645 statement for the &x case.
3647 2002-02-14 Miguel de Icaza <miguel@ximian.com>
3649 * class.cs (Property.Define, Method.Define): Remove newslot when
3652 * modifiers.cs: My use of NewSlot when `Abstract' was set was
3653 wrong. NewSlot should only be used if the `new' keyword is present.
3655 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
3656 locating our system dir. Sorry about this.
3658 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3660 * driver.cs (GetSystemDir): Compute correctly the location of our
3661 system assemblies. I was using the compiler directory instead of
3662 the library directory.
3664 2002-02-13 Ravi Pratap <ravi@ximian.com>
3666 * expression.cs (BetterFunction): Put back in what Miguel commented out
3667 since it is the correct fix. The problem is elsewhere ;-)
3669 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
3670 parameters of the parms method are themselves compatible or not !
3672 (StandardConversionExists): Fix very dangerous bug where we were forgetting
3673 to check that a class implements an interface before saying that an implicit
3674 conversion was allowed. Use ImplementsInterface to do the checking.
3676 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3678 * class.cs (Method.Define): Track whether we are an explicit
3679 implementation or not. And only call DefineMethodOverride if we
3680 are an explicit implementation.
3682 (Property.DefineMethod): Ditto.
3684 2002-02-11 Ravi Pratap <ravi@ximian.com>
3686 * expression.cs (BetterFunction): Catch hideous bug which was
3687 preventing us from detecting ambiguous calls due to implicit casts i.e
3690 2002-01-29 Miguel de Icaza <miguel@ximian.com>
3692 * support.cs (Pair): Remove un-needed method. I figured why I was
3693 getting the error in cs-parser.jay, the variable in a foreach loop
3694 is readonly, and the compiler does not really treat this as a variable.
3696 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
3697 instead of EQUALS in grammar.
3699 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
3701 * expression.cs (Unary.DoResolve): Check whether the argument is
3704 2002-01-28 Miguel de Icaza <miguel@ximian.com>
3706 * support.cs: Api for Pair to set a value. Despite the fact that
3707 the variables are public the MS C# compiler refuses to compile
3708 code that accesses the field if the variable is part of a foreach
3711 * statement.cs (Fixed): Begin implementation of the fixed
3714 (Block.AddVariable): Return the VariableInfo on success and null
3715 on failure instead of true/false.
3717 * cs-parser.jay (foreach): Catch errors on variables already
3718 defined (we were ignoring this value before) and properly unwind
3721 (fixed_statement): grammar for the fixed statement.
3723 2002-01-25 Miguel de Icaza <miguel@ximian.com>
3725 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
3726 pointer types to be incretemented.
3728 (SizeOf): Implement.
3730 * cs-parser.jay (pointer_member_access): Implement
3731 expr->IDENTIFIER production.
3733 * expression.cs (IndexerAccess.DoResolve, ArrayAccess.DoResolve,
3734 MemberAccess.DoResolve, Invocation.DoResolve): Check for pointers
3737 (Unary): Implement indirection.
3739 * ecore.cs (Expression.UnsafeError): Reports error 214 (pointer
3740 use in non-unsafe context).
3742 (SimpleName.DoResolve): Check for pointers in field access on safe
3745 (Expression.LoadFromPtr): Factor the load-indirect code in this
3746 function. This was duplicated in UnboxCast and ParameterReference
3748 2002-01-24 Miguel de Icaza <miguel@ximian.com>
3750 * expression.cs (ComposedCast): report an error if a pointer cast
3751 is used in a safe region.
3753 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
3754 pointer type casts in unsafe context.
3756 * codegen.cs (EmitContext): Set up IsUnsafe.
3758 * cs-parser.jay (non_expression_type): Add productions for pointer
3761 * expression.cs (Invocation.EmitCall): Remove chunk of buggy
3762 code. We should not use force into static mode if the method is
3763 not virtual. Fixes bug in MIS
3765 * statement.cs (Do.Emit, While.Emit, For.Emit,
3766 Statement.EmitBoolExpression): Add support to Do and While to
3767 propagate infinite loop as `I do return' semantics.
3769 Improve the For case to also test for boolean constants.
3771 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
3772 to the list of attributes we can add.
3774 Remove `EmitContext' argument.
3776 * class.cs (Method.Define): Apply parameter attributes.
3777 (Constructor.Define): Apply parameter attributes.
3778 (MethodCore.LabelParameters): Move here the core of labeling
3781 * support.cs (ReflectionParameters.ParameterModifier,
3782 InternalParameters.ParameterModifier): Use IsByRef on the type and
3783 only return the OUT bit for these parameters instead of in/out/ref
3786 This is because I miss-understood things. The ParameterInfo.IsIn
3787 and IsOut represent whether the parameter has the [In] and [Out]
3790 2002-01-22 Miguel de Icaza <miguel@ximian.com>
3792 * ecore.cs (FieldExpr.Emit): Release temporaries.
3794 * assign.cs (LocalTemporary.Release): new function.
3796 * codegen.cs (EmitContext.GetTemporaryStorage,
3797 EmitContext.FreeTemporaryStorage): Rework the way we deal with
3798 temporary storage. Now we can "put back" localbuilders when we
3801 2002-01-21 Miguel de Icaza <miguel@ximian.com>
3803 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
3804 need to make a copy of the variable to generate verifiable code.
3806 2002-01-19 Miguel de Icaza <miguel@ximian.com>
3808 * driver.cs: Compute dynamically the system directory.
3810 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
3811 Slower, but more generally useful. Used by the abstract
3812 registering implementation.
3814 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
3815 the rules for the special rule on Type/instances. First check if
3816 we have the same name, and if so, try that special static path
3817 rather than the instance path.
3819 2002-01-18 Miguel de Icaza <miguel@ximian.com>
3821 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
3824 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
3825 Enum, ValueType, Delegate or Array for non-corlib compiles.
3827 * cs-tokenizer.cs: Catch long identifiers (645)
3829 * typemanager.cs (IndexerPropetyName): Ravi never tested this
3832 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
3833 fix, we were returning too early, so we were not registering
3834 pending methods from abstract classes.
3836 Do not register pending methods if the class is abstract.
3838 * expression.cs (Conditional.DoResolve): Report circular implicit
3839 conversions when we neecd to compute it for conditional
3842 (Is.DoResolve): If the expression is always of the provided type,
3843 flag warning 183. If the expression can not ever be of the
3844 provided type flag warning 184.
3846 * class.cs: Catch 169 as well.
3848 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
3851 2002-01-18 Nick Drochak <ndrochak@gol.com>
3853 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.
3855 2002-01-17 Miguel de Icaza <miguel@ximian.com>
3857 * interface.cs: (PopulateMethod): Check for pointers being defined
3858 only if the unsafe context is active.
3859 (PopulateProperty): ditto.
3860 (PopulateIndexer): ditto.
3862 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
3863 specified. If pointers are present, make sure that they are
3864 present in an unsafe context.
3865 (Constructor, Constructor.Define): ditto.
3866 (Field, Field.Define): ditto.
3867 (Property, Property.Define): ditto.
3868 (Event, Event.Define): ditto.
3870 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
3871 hashtable if there are classes or structs defined.
3873 * expression.cs (LocalVariableReference.DoResolve): Simplify this
3874 code, as the constant resolution moved.
3876 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
3877 the metadata, so we can flag error 133.
3879 * decl.cs (MemberCore.UnsafeOK): New function to test that a
3880 pointer is being declared in an unsafe context.
3882 2002-01-16 Miguel de Icaza <miguel@ximian.com>
3884 * modifiers.cs (Modifiers.Check): Require a Location argument.
3885 Report error 227 for Unsafe use.
3887 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
3889 * statement.cs (For.Emit): If the test is null, then report that
3890 we do `return', as we wont reach anything afterwards.
3892 (Switch.SwitchGoverningType): Track the expression that matched
3895 * driver.cs: Allow negative numbers as an error code to flag.
3897 * cs-parser.jay: Handle 1551.
3899 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
3901 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3903 * cs-parser.jay: Report 1518 (type declaration can only contain
3904 class, struct, interface, enum or delegate)
3906 (switch_label): Report 1523 (keywords `case' or `default' must
3909 (opt_switch_sections): Report 1522 (empty switch)
3911 * driver.cs: Report 1515 (response file specified multiple times)
3912 Report 1516 (Source file specified multiple times).
3914 * expression.cs (Argument.Resolve): Signal 1510
3916 (BaseAccess.Resolve, BaseIndexer.Resolve): Signal 1511 (base
3917 access not allowed in static code)
3919 2002-01-11 Ravi Pratap <ravi@ximian.com>
3921 * typemanager.cs (IsPointerType): Utility method which we are going
3924 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
3925 the object type, so we take care of that.
3927 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
3929 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
3930 added to non-params parameters :-)
3932 * typemanager.cs (CSharpName): Include 'void' type too.
3934 (void_ptr_type): Include in the set of core types.
3936 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
3939 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
3942 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
3943 completely forgotten about it.
3945 2002-01-10 Ravi Pratap <ravi@ximian.com>
3947 * cs-parser.jay (pointer_type): Add. This begins our implementation
3948 of parsing rules for unsafe code.
3950 (unsafe_statement): Implement.
3952 (embedded_statement): Modify to include the above.
3954 * statement.cs (Unsafe): Implement new class for unsafe blocks.
3956 * codegen.cs (EmitContext.InUnsafe): Add. This determines
3957 if the current context is an unsafe one.
3959 * cs-parser.jay (local_variable_pointer_type): Since local variable types
3960 are handled differently, we need separate rules for them.
3962 (local_variable_declaration): Update to use local_variable_pointer_type
3963 to allow variable declarations of unmanaged pointer types.
3965 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
3968 * ../errors/cs0214.cs : Add.
3970 2002-01-16 Nick Drochak <ndrochak@gol.com>
3972 * makefile: remove 'response' file when cleaning.
3974 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3976 * cs-parser.jay: Report 1524.
3978 2002-01-14 Miguel de Icaza <miguel@ximian.com>
3980 * typemanager.cs (RegisterMethod): drop checking if we have
3981 registered this from here
3983 2002-01-12 Miguel de Icaza <miguel@ximian.com>
3985 * class.cs (Method.EmitDestructor): Implement calling our base
3988 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
3991 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
3992 this routine and will wrap the call in a try/catch block. Deal
3995 2002-01-11 Miguel de Icaza <miguel@ximian.com>
3997 * ecore.cs (Expression.MemberLookup): instead of taking a
3998 parameter `same_type' that was used to tell whether we could
3999 access private members we compute our containing type from the
4002 (FieldExpr): Added partial support for volatile fields. This does
4003 not work for volatile fields exposed from assemblies, as I can not
4004 figure out how to extract the modreq from it.
4006 Updated all the source files to use this.
4008 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
4009 because it is referenced by MemberLookup very often.
4011 2002-01-09 Ravi Pratap <ravi@ximian.com>
4013 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
4014 TypeBuilder.GetCustomAttributes to retrieve what we need.
4016 Get rid of redundant default_member_attr_type as this is the same as
4017 default_member_type which already exists.
4019 * interface.cs, attribute.cs : Update accordingly.
4021 2002-01-08 Miguel de Icaza <miguel@ximian.com>
4023 * typemanager.cs: Enable IndexerPropertyName again. It does not
4024 work for TYpeBuilders though. Ravi, can you please fix this?
4026 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
4028 * expression.cs (Argument.Emit): Handle the case of ref objects
4029 being passed to ref functions;
4031 (ParameterReference.EmitLoad): Loads the content of the pointer
4032 without dereferencing.
4034 2002-01-07 Miguel de Icaza <miguel@ximian.com>
4036 * cs-tokenizer.cs: Implemented the pre-processing expressions.
4038 2002-01-08 Ravi Pratap <ravi@ximian.com>
4040 * class.cs (Indexer.DefineMethod): Incorporate the interface
4041 type in the name of the method if we are doing explicit interface
4044 * expression.cs (ConversionExists): Remove as it is completely obsolete.
4046 (BetterConversion): Fix extremely trivial bug where we were referring to
4047 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
4050 * ../errors/bug16.cs : Add although we have fixed it.
4052 2002-01-07 Miguel de Icaza <miguel@ximian.com>
4054 * expression.cs (BaseIndexer): Begin implementation.
4056 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
4058 * cs-parser.jay (indexer_declarator): Use qualified_identifier
4059 production directly to remove a shift/reduce, and implement
4060 explicit interface implementation.
4062 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
4063 after a floating point suffix.
4065 * expression.cs (DoNumericPromotions): Improved the conversion for
4066 uint/uint. If we have a constant, we avoid doing a typecast to a
4069 * class.cs (Indexer): Implement explicit interface implementation
4072 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
4074 * class.cs: make the default instance constructor public and hidebysig.
4076 2001-01-03 Ravi Pratap <ravi@ximian.com>
4078 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
4079 so we can call it from elsewhere.
4081 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
4082 we emit it internally if the class has a defined indexer; otherwise the user
4083 emits it by decorating the class definition with the DefaultMemberAttribute.
4085 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
4086 attribute is not used on a type which defines an indexer.
4088 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
4089 character when we skip whitespace.
4091 * ../errors/cs0646.cs : Add.
4093 2002-01-03 Miguel de Icaza <miguel@ximian.com>
4095 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
4098 * makefile: Add practical target `mcs3.exe' which builds the third
4099 generation compiler.
4101 * expression.cs (New): Fix structures constructor calling.
4103 * class.cs (Property, Method, Indexer): Emit Final flag on the
4104 method if we are an interface implementation and we are not
4107 * ecore.cs (PropertyExpr): New public field `IsBase', tells
4108 whether this property is referencing a `base' method.
4110 * expression.cs (Invocation.EmitCall): take an extra argument:
4111 is_base, this is used to determine whether the `call' or
4112 `callvirt' opcode should be used.
4115 * delegate.cs: update EmitCall.
4117 * class.cs (Method.Define): Set NewSlot for the cases where we are
4118 not implementing an interface method.
4120 (Property.Define): ditto.
4122 2002-01-02 Miguel de Icaza <miguel@ximian.com>
4124 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
4125 'r'. Allows mcs to parse itself fully.
4127 2002-01-02 Ravi Pratap <ravi@ximian.com>
4129 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
4130 of the number of initializers that require the InitializeArray method.
4132 (CheckIndices): Store the Expression in all cases - not the plain value. Also
4133 update the above field where necessary.
4135 (MakeByteBlob): Update accordingly.
4137 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
4140 (EmitDynamicInitializers): Update in accordance with the new optimization.
4142 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
4143 same OpCode applies.
4145 * cs-parser.jay : Fix some glaring errors I introduced.
4147 2002-01-01 Ravi Pratap <ravi@ximian.com>
4149 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
4150 so that we can check for name clashes there too.
4152 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
4153 for interface indexers.
4155 * interfaces.cs (Define): Emit the default member attribute.
4157 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
4158 variable was being referred to while setting the value ;-)
4160 2002-01-01 Miguel de Icaza <miguel@ximian.com>
4162 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
4163 byte-by-byte information when we know the data is zero.
4165 Make the block always a multiple of 4, because
4166 DefineInitializedData has a bug.
4168 * assign.cs: Fix, we should assign from the temporary, not from
4171 * expression.cs (MakeByteBlob): Fix my incorrect code.
4173 2001-12-31 Miguel de Icaza <miguel@ximian.com>
4175 * typemanager.cs (EnumToUnderlying): This function is used to get
4176 the underlying type from an enumeration, because it does not
4179 * constant.cs: Use the I4_S form for values between -128 and 127.
4181 * statement.cs (Block.LookupLabel): Looks up a label.
4182 (Block): Drop support for labeled blocks.
4184 (LabeledStatement): New kind of statement that represents a label
4187 (Goto): Finally implement this bad boy.
4189 * cs-parser.jay: Update to reflect new mechanism to implement
4192 2001-12-30 Miguel de Icaza <miguel@ximian.com>
4194 * codegen.cs (EmitContext.This): a codegen property that keeps the
4195 a single instance of this instead of creating many different this
4198 * delegate.cs (Delegate.DoResolve): Update to use the property;
4200 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
4202 * expression.cs (BaseAccess.DoResolve): Ditto.
4204 2001-12-29 Ravi Pratap <ravi@ximian.com>
4206 * typemanager.cs (methodimpl_attr_type): Add to hold the type
4207 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
4209 (InitCoreTypes): Update accordingly.
4211 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
4212 so we can quickly store the state.
4214 (ApplyAttributes): Set the correct implementation flags
4215 for InternalCall methods.
4217 2001-12-29 Miguel de Icaza <miguel@ximian.com>
4219 * expression.cs (EmitCall): if a method is not virtual, then do
4220 not use callvirt on it.
4222 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
4223 user defined stuff) requires the use of stobj, which takes an
4224 address on the stack instead of an array and an index. So emit
4225 the Ldelema operation for it.
4227 (EmitStoreOpcode): Use stobj for valuetypes.
4229 (UnaryMutator.EmitCode): Use the right 1 value depending on
4230 whether we are dealing with int64/uint64, float or doubles.
4232 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
4233 constructors that I implemented last night.
4235 (Constructor.IsDefault): Fix to work properly for static
4238 * cs-parser.jay (CheckDef): report method signature errors.
4239 Update error number 103 to be 132.
4241 * decl.cs: New AdditionResult enumeration value: MethodExists.
4242 Although we do this check for methods later on in the semantic
4243 analysis, catching repeated default constructors is so easy that
4244 we catch these here.
4246 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
4249 (ParameterReference.EmitAssign, Emit): handle
4252 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
4253 (ArrayAccess.EmitStoreOpcode): ditto.
4255 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
4257 * expression.cs (MakeByteBlob): Complete all the missing types
4258 (uint, short, ushort, byte, sbyte)
4260 * class.cs: Only init instance field initializers on instance
4263 Rename `constructors' to instance_constructors.
4265 (TypeContainer.AddConstructor): Only add constructors to the list
4266 if it is not static.
4268 Make sure that we handle default_static_constructor independently
4269 everywhere where we handle instance_constructors
4271 2001-12-28 Miguel de Icaza <miguel@ximian.com>
4273 * class.cs: Do not lookup or create a base initializer for a
4276 (ConstructorInitializer.Resolve): use the proper type to lookup
4279 * cs-parser.jay: Report error 1585 (modifiers between type and name).
4281 * enum.cs, interface.cs: Remove CloseType, this is taken care by
4284 * decl.cs: CloseType is now an virtual method, the default
4285 implementation just closes this type.
4287 2001-12-28 Ravi Pratap <ravi@ximian.com>
4289 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
4290 to PreserveSig by default. Also emit HideBySig on such methods.
4292 Basically, set the defaults to standard values.
4294 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
4295 argument, if candidate is better, it can't be worse than the best !
4297 (Invocation): Re-write bits to differentiate between methods being
4298 applicable in their expanded form and their normal form - for params
4301 Get rid of use_standard everywhere as only standard conversions are allowed
4302 in overload resolution.
4304 More spec conformance.
4306 2001-12-27 Miguel de Icaza <miguel@ximian.com>
4308 * driver.cs: Add --timestamp, to see where the compiler spends
4311 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
4312 `this' in static code.
4314 (SimpleName.DoResolve): Implement in terms of a helper function
4315 that allows static-references to be passed upstream to
4318 (Expression.ResolveWithSimpleName): Resolve specially simple
4319 names when called by MemberAccess to implement the special
4322 (Expression.ImplicitReferenceConversion): Handle conversions from
4323 Null to reference types before others, as Null's type is
4326 * expression.cs (Invocation.EmitCall): Handle the special case of
4327 calling methods declared on a reference type from a ValueType
4328 (Base classes System.Object and System.Enum)
4330 (MemberAccess.Resolve): Only perform lookups on Enumerations if
4331 the left hand side is a TypeExpr, not on every enumeration.
4333 (Binary.Resolve): If types are reference types, then do a cast to
4334 object on operators != and == of both arguments.
4336 * typemanager.cs (FindMembers): Extract instance and static
4337 members if requested.
4339 * interface.cs (PopulateProperty): Use void_type instead of null
4340 as the return type for the setter method.
4342 (PopulateIndexer): ditto.
4344 2001-12-27 Ravi Pratap <ravi@ximian.com>
4346 * support.cs (ReflectionParameters): Fix minor bug where we
4347 were examining the wrong parameter for the ParamArray attribute.
4349 Cope with requests for the type of the parameter at position
4350 greater than the params parameter's. We now return the element
4351 type of the params array as that makes more sense.
4353 * expression.cs (Invocation.IsParamsMethodApplicable): Update
4354 accordingly as we no longer have to extract the element type
4357 (Invocation.OverloadResolve): Update.
4359 2001-12-27 Miguel de Icaza <miguel@ximian.com>
4361 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
4362 against IEnumerator, test whether the return value is a descendant
4363 of the IEnumerator interface.
4365 * class.cs (Indexer.Define): Use an auxiliary method to implement
4366 the other bits of the method definition. Begin support for
4367 explicit interface implementation.
4369 (Property.DefineMethod): Use TypeManager.void_type instead of null
4370 for an empty return value.
4372 2001-12-26 Miguel de Icaza <miguel@ximian.com>
4374 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
4375 dealing with a FieldExpr which is composed of a FieldBuilder, in
4376 the code path we did extract the constant, but we should have
4377 obtained the underlying value to be able to cast it (otherwise we
4378 end up in an infinite loop, this is what Ravi was running into).
4380 (ArrayCreation.UpdateIndices): Arrays might be empty.
4382 (MemberAccess.ResolveMemberAccess): Add support for section
4383 14.5.4.1 that deals with the special case of E.I when E is a type
4384 and something else, that I can be a reference to a static member.
4386 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
4387 handle a particular array type to create byte blobs, it is just
4388 something we dont generate byteblobs for.
4390 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
4393 * location.cs (Push): remove the key from the hashtable that we
4394 are about to add. This happens for empty files.
4396 * driver.cs: Dispose files after we have parsed them.
4398 (tokenize): new function that only runs the tokenizer on its
4399 input, for speed testing.
4401 2001-12-26 Ravi Pratap <ravi@ximian.com>
4403 * class.cs (Event.Define): Define the private field only if there
4404 are no accessors defined.
4406 * expression.cs (ResolveMemberAccess): If there is no associated
4407 field with the event, that means we have an event defined with its
4408 own accessors and we should flag error cs0070 since transforming
4409 ourselves into a field is not valid in that case.
4411 * ecore.cs (SimpleName.DoResolve): Same as above.
4413 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
4414 and charset to sane values.
4416 2001-12-25 Ravi Pratap <ravi@ximian.com>
4418 * assign.cs (DoResolve): Perform check on events only if they
4419 are being accessed outside the declaring type.
4421 * cs-parser.jay (event_declarations): Update rules to correctly
4422 set the type of the implicit parameter etc.
4424 (add_accessor, remove_accessor): Set current local parameters.
4426 * expression.cs (Binary): For delegate addition and subtraction,
4427 cast the return value from the method into the appropriate delegate
4430 2001-12-24 Ravi Pratap <ravi@ximian.com>
4432 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
4433 of these as the workaround is unnecessary.
4435 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
4436 delegate data - none of that is needed at all.
4438 Re-write bits to extract the instance expression and the delegate method
4441 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
4444 * attribute.cs (ApplyAttributes): New method to take care of common tasks
4445 of attaching attributes instead of duplicating code everywhere.
4447 * everywhere : Update code to do attribute emission using the above method.
4449 2001-12-23 Miguel de Icaza <miguel@ximian.com>
4451 * expression.cs (IsParamsMethodApplicable): if there are not
4452 parameters, return immediately.
4454 * ecore.cs: The 0 literal can be implicity converted to an enum
4457 (SimpleName.DoResolve): First lookup the type, then lookup the
4460 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
4461 want to get its address. If the InstanceExpression is not
4462 addressable, store the result in a temporary variable, then get
4465 * codegen.cs: Only display 219 errors on warning level or above.
4467 * expression.cs (ArrayAccess): Make it implement the
4468 IMemoryLocation interface.
4470 (Binary.DoResolve): handle the operator == (object a, object b)
4471 and operator != (object a, object b) without incurring into a
4472 BoxedCast (because 5 != o should never be performed).
4474 Handle binary enumerator operators.
4476 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
4477 value type, otherwise use Ldelem_ref.
4479 Use precomputed names;
4481 (AddressOf): Implement address of
4483 * cs-parser.jay (labeled_statement): Fix recursive block
4484 addition by reworking the production.
4486 * expression.cs (New.DoEmit): New has a special case:
4488 If we are dealing with a ValueType, we have a few
4489 situations to deal with:
4491 * The target of New is a ValueType variable, that is
4492 easy, we just pass this as the variable reference
4494 * The target of New is being passed as an argument,
4495 to a boxing operation or a function that takes a
4498 In this case, we need to create a temporary variable
4499 that is the argument of New.
4502 2001-12-23 Ravi Pratap <ravi@ximian.com>
4504 * rootcontext.cs (LookupType): Check that current_type is not null before
4505 going about looking at nested types.
4507 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
4508 not implement the IAssignMethod interface any more.
4510 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
4511 where we tranform them into FieldExprs if they are being resolved from within
4514 * ecore.cs (SimpleName.DoResolve): Do the same here.
4516 * assign.cs (DoResolve, Emit): Clean up code considerably.
4518 * ../errors/bug10.cs : Add.
4520 * ../errors/cs0070.cs : Add.
4522 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
4524 * assign.cs : Get rid of EventIsLocal everywhere.
4526 2001-12-23 Miguel de Icaza <miguel@ximian.com>
4528 * ecore.cs (ConvertIntLiteral): finished the implementation.
4530 * statement.cs (SwitchLabel): Convert the value we are using as a
4531 key before looking up the table.
4533 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4535 * codegen.cs (EmitTopBlock): Require a Location argument now.
4537 * cs-parser.jay (constructor_declarator): We need to setup
4538 current_local_parameters before we parse the
4539 opt_constructor_initializer, to allow the variables to be bound
4540 to the constructor arguments.
4542 * rootcontext.cs (LookupType): First lookup nested classes in our
4543 class and our parents before we go looking outside our class.
4545 * expression.cs (ConstantFold): Extract/debox the values at the
4548 * rootcontext.cs (EmitCode): Resolve the constants first before we
4549 resolve the types. This is not really needed, but it helps debugging.
4551 * statement.cs: report location.
4553 * cs-parser.jay: pass location to throw statement.
4555 * driver.cs: Small bug fix.
4557 * report.cs: Updated format to be 4-zero filled digits.
4559 2001-12-22 Ravi Pratap <ravi@ximian.com>
4561 * expression.cs (CheckIndices): Fix minor bug where the wrong
4562 variable was being referred to ;-)
4564 (DoEmit): Do not call EmitStaticInitializers when the
4565 underlying type is System.Object.
4567 2001-12-21 Ravi Pratap <ravi@ximian.com>
4569 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
4570 and do the usual workaround for SRE.
4572 * class.cs (MyEventBuilder.EventType): New member to get at the type
4573 of the event, quickly.
4575 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
4577 * assign.cs (Assign.DoResolve): Handle the case when the target
4578 is an EventExpr and perform the necessary checks.
4580 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
4583 (SimpleName.MemberStaticCheck): Include check for EventExpr.
4585 (EventExpr): Set the type in the constructor itself since we
4586 are meant to be born fully resolved.
4588 (EventExpr.Define): Revert code I wrote earlier.
4590 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
4591 instance expression is null. The instance expression is a This in that case
4592 or a null, depending on whether it is a static method or not.
4594 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
4595 refers to more than one method.
4597 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
4598 and accordingly flag errors.
4600 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4602 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
4604 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4606 * location.cs (ToString): Provide useful rutine.
4608 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4610 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
4611 objects, return the actual integral boxed.
4613 * statement.cs (SwitchLabel): define an ILLabel for each
4616 (Switch.CheckSwitch): If the value is a Literal, extract
4617 the underlying literal.
4619 Also in the unused hashtable we had, add the SwitchLabel so we can
4620 quickly look this value up.
4622 * constant.cs: Implement a bunch of new constants. Rewrite
4623 Literal based on this. Made changes everywhere to adapt to this.
4625 * expression.cs (Expression.MakeByteBlob): Optimize routine by
4626 dereferencing array only once, and also copes with enumrations.
4628 bytes are two bytes wide, not one.
4630 (Cast): Perform constant conversions.
4632 * ecore.cs (TryImplicitIntConversion): Return literals instead of
4633 wrappers to the literals here.
4635 * expression.cs (DoNumericPromotions): long literals can converted
4636 to ulong implicity (this is taken care of elsewhere, but I was
4639 * ecore.cs (Expression.Literalize): Make the return type Literal,
4640 to improve type checking.
4642 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
4644 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4646 * literal.cs: Revert code from ravi that checked the bounds. The
4647 bounds are sane by the definition of the type itself.
4649 * typemanager.cs: Fix implementation of ImplementsInterface. We
4650 need to actually look up in our parent hierarchy for interfaces
4653 * const.cs: Use the underlying type for enumerations
4655 * delegate.cs: Compute the basename for the delegate creation,
4656 that should fix the delegate test case, and restore the correct
4657 Type Lookup semantics in rootcontext
4659 * rootcontext.cs: Revert Ravi's last patch. The correct way of
4660 referencing a nested type with the Reflection API is using the "+"
4663 * cs-parser.jay: Do not require EOF token at the end.
4665 2001-12-20 Ravi Pratap <ravi@ximian.com>
4667 * rootcontext.cs (LookupType): Concatenate type names with
4668 a '.' instead of a '+' The test suite passes again.
4670 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
4671 field of the enumeration.
4673 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
4674 the case when the member is an EventExpr.
4676 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
4677 static has an associated instance expression.
4679 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
4681 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
4683 * class.cs (Event.Define): Register event and perform appropriate checks
4686 We define the Add and Remove methods even if the use provides none because
4687 in that case, we provide default implementations ourselves.
4689 Define a private field of the type of the event. This is done by the CSC compiler
4690 and we should be doing it too ;-)
4692 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
4693 More methods we use in code we generate.
4695 (multicast_delegate_type, delegate_type): Two separate types since the distinction
4698 (InitCoreTypes): Update accordingly for the above.
4700 * class.cs (Event.Emit): Generate code for default accessors that we provide
4702 (EmitDefaultMethod): Do the job in the above.
4704 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
4707 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4709 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
4710 builders even if we were missing one.
4712 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
4713 pass the Basename as our class name instead of the Name. The
4714 basename will be correctly composed for us.
4716 * parameter.cs (Paramters): Now takes a Location argument.
4718 * decl.cs (DeclSpace.LookupType): Removed convenience function and
4719 make all the code call directly LookupType in RootContext and take
4720 this chance to pass the Location information everywhere.
4722 * Everywhere: pass Location information.
4724 2001-12-19 Miguel de Icaza <miguel@ximian.com>
4726 * class.cs (Constructor.Define): Updated way of detecting the
4727 length of the parameters.
4729 (TypeContainer.DefineType): Use basename as the type name for
4732 (TypeContainer.Define): Do not recursively define types here, as
4733 definition is taken care in order by the RootContext.
4735 * tree.cs: Keep track of namespaces in a per-file basis.
4737 * parameter.cs (Parameter.ComputeSignature): Update to use
4740 (Parameters.GetSignature): ditto.
4742 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
4743 instead of a TypeContainer.
4745 (Interface.SemanticAnalysis): Use `this' instead of our parent to
4746 resolve names. Because we need to be resolve in our context, not
4749 * driver.cs: Implement response files.
4751 * class.cs (TypeContainer.DefineType): If we are defined, do not
4754 (Event.Emit): Emit the code for add/remove handlers.
4755 (Event.Define): Save the MethodBuilders for add/remove.
4757 * typemanager.cs: Use pair here too.
4759 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
4760 DictionaryEntry requires the first argument to be non-null.
4762 (enum_declaration): Compute full name for registering the
4765 (delegate_declaration): Instead of using
4766 formal_parameter_list, use opt_formal_parameter_list as the list
4769 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
4770 (EventParsing): New property that controls whether `add' and
4771 `remove' are returned as tokens or identifiers (for events);
4773 2001-12-19 Ravi Pratap <ravi@ximian.com>
4775 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
4776 use MyEventBuilder only and let it wrap the real builder for us.
4778 (MyEventBuilder): Revamp constructor etc.
4780 Implement all operations that we perform on EventBuilder in precisely the same
4783 (FindMembers): Update to use the EventBuilder member.
4785 (Event.Emit): Update accordingly.
4787 2001-12-18 Ravi Pratap <ravi@ximian.com>
4789 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
4790 by calling the appropriate methods.
4792 (GetCustomAttributes): Make stubs as they cannot possibly do anything
4795 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
4797 2001-12-17 Ravi Pratap <ravi@ximian.com>
4799 * delegate.cs (Delegate.Populate): Check that the return type
4800 and various parameters types are indeed accessible.
4802 * class.cs (Constructor.Define): Same here.
4804 (Field.Define): Ditto.
4806 (Event.Define): Ditto.
4808 (Operator.Define): Check that the underlying Method defined itself
4809 correctly - so it's MethodBuilder should not be null.
4811 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
4812 expression happens to be null.
4814 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
4815 members but as of now we don't seem to be able to do anything really useful with it.
4817 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
4818 not the EventBuilder.
4820 2001-12-18 Miguel de Icaza <miguel@ximian.com>
4822 * cs-tokenizer.cs: Add support for defines.
4823 Add support for #if, #elif, #else, #endif
4825 (eval_var): evaluates a variable.
4826 (eval): stubbed for evaluating functions.
4828 * cs-parser.jay: Pass the defines information
4830 * driver.cs: Add --define command line option.
4832 * decl.cs: Move MemberCore here.
4834 Make it the base class for DeclSpace. This allows us to catch and
4835 report 108 and 109 for everything now.
4837 * class.cs (TypeContainer.Define): Extract all the members
4838 before populating and emit the warning 108 (new keyword required
4839 to override) instead of having each member implement this.
4841 (MemberCore.Define): New abstract method, we will be using this in
4842 the warning reporting engine in Populate.
4844 (Operator.Define): Adjust to new MemberCore protocol.
4846 * const.cs (Const): This does not derive from Expression, it is a
4847 temporary object we use to create fields, it is a MemberCore.
4849 * class.cs (Method.Define): Allow the entry point to be in a
4852 * driver.cs: Rewrite the argument handler to clean it up a bit.
4854 * rootcontext.cs: Made it just an auxiliary namespace feature by
4855 making everything static.
4857 * driver.cs: Adapt code to use RootContext type name instead of
4860 * delegate.cs: Remove RootContext argument.
4862 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
4865 * class.cs (Event.Define): The lookup can fail.
4867 * cs-tokenizer.cs: Begin implementation of pre-procesor.
4869 * expression.cs: Resolve the this instance before invoking the code.
4871 2001-12-17 Miguel de Icaza <miguel@ximian.com>
4873 * cs-parser.jay: Add a production in element_access that allows
4874 the thing to become a "type" reference. This way we can parse
4875 things like "(string [])" as a type.
4877 Note that this still does not handle the more complex rules of
4881 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
4883 * ecore.cs: (CopyNewMethods): new utility function used to
4884 assemble the list of methods from running FindMembers.
4886 (MemberLookup): Rework FindMembers so that
4888 2001-12-16 Miguel de Icaza <miguel@ximian.com>
4890 * class.cs (TypeContainer): Remove Delegates who fail to be
4893 * delegate.cs (Populate): Verify that we dont get null return
4894 values. TODO: Check for AsAccessible.
4896 * cs-parser.jay: Use basename to emit error 574 (destructor should
4897 have the same name as container class), not the full name.
4899 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
4900 possible representation.
4902 Also implements integer type suffixes U and L.
4904 2001-12-15 Miguel de Icaza <miguel@ximian.com>
4906 * expression.cs (ArrayCreation.DoResolve): We need to do the
4907 argument resolution *always*.
4909 * decl.cs: Make this hold the namespace. Hold the root context as
4911 (LookupType): Move here.
4913 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
4915 * location.cs (Row, Name): Fixed the code, it was always returning
4916 references to the first file.
4918 * interface.cs: Register properties defined through interfaces.
4920 * driver.cs: Add support for globbing on the command line
4922 * class.cs (Field): Make it derive from MemberCore as well.
4925 2001-12-15 Ravi Pratap <ravi@ximian.com>
4927 * class.cs (Event::Define): Check that the type of the event is a delegate
4928 type else flag error #66.
4930 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
4933 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
4934 values of EntryPoint, CharSet etc etc.
4936 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
4938 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
4939 be null and we should ignore this. I am not sure if this is really clean. Apparently,
4940 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
4941 which needs this to do its work.
4943 * ../errors/cs0066.cs : Add.
4945 2001-12-14 Miguel de Icaza <miguel@ximian.com>
4947 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
4950 * class.cs: (MethodSignature.MethodSignature): Removed hack that
4951 clears out the parameters field.
4952 (MemberSignatureCompare): Cleanup
4954 (MemberCore): New base class used to share code between MethodCore
4957 (RegisterRequiredImplementations) BindingFlags.Public requires
4958 either BindingFlags.Instace or Static. Use instance here.
4960 (Property): Refactored code to cope better with the full spec.
4962 * parameter.cs (GetParameterInfo): Return an empty array instead
4965 * class.cs (Property): Abstract or extern properties have no bodies.
4967 * parameter.cs (GetParameterInfo): return a zero-sized array.
4969 * class.cs (TypeContainer.MethodModifiersValid): Move all the
4970 method modifier validation to the typecontainer so we can reuse
4973 (MethodCore.ParameterTypes): return an empty sized array of types.
4975 (Property.Define): Test property modifier validity.
4977 Add tests for sealed/override too.
4979 (Method.Emit): abstract or extern methods have no bodies.
4981 2001-12-14 Ravi Pratap <ravi@ximian.com>
4983 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
4986 (Method::Define, ::Emit): Modify accordingly.
4988 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
4990 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
4992 * makefile: Pass in /unsafe.
4994 2001-12-13 Miguel de Icaza <miguel@ximian.com>
4996 * class.cs (MakeKey): Kill routine.
4998 * class.cs (TypeContainer.Define): Correctly define explicit
4999 method implementations (they require the full interface name plus
5002 * typemanager.cs: Deply the PtrHashtable here and stop using the
5003 lame keys. Things work so much better.
5005 This of course broke everyone who depended on `RegisterMethod' to
5006 do the `test for existance' test. This has to be done elsewhere.
5008 * support.cs (PtrHashtable): A hashtable that avoid comparing with
5009 the object stupid Equals method (because, that like fails all over
5010 the place). We still do not use it.
5012 * class.cs (TypeContainer.SetRequiredInterface,
5013 TypeContainer.RequireMethods): Killed these two routines and moved
5014 all the functionality to RegisterRequiredImplementations.
5016 (TypeContainer.RegisterRequiredImplementations): This routine now
5017 registers all the implementations required in an array for the
5018 interfaces and abstract methods. We use an array of structures
5019 which can be computed ahead of time to reduce memory usage and we
5020 also assume that lookups are cheap as most classes will not
5021 implement too many interfaces.
5023 We also avoid creating too many MethodSignatures.
5025 (TypeContainer.IsInterfaceMethod): Update and optionally does not
5026 clear the "pending" bit if we find that there are problems with
5029 (TypeContainer.VerifyPendingMethods): Update to report errors of
5030 methods that look like implementations but are not.
5032 (TypeContainer.Define): Add support for explicit interface method
5035 2001-12-12 Miguel de Icaza <miguel@ximian.com>
5037 * typemanager.cs: Keep track of the parameters here instead of
5038 being a feature of the TypeContainer.
5040 * class.cs: Drop the registration of parameters here, as
5041 InterfaceMethods are also interface declarations.
5043 * delegate.cs: Register methods with the TypeManager not only with
5044 the TypeContainer. This code was buggy.
5046 * interface.cs: Full registation here.
5048 2001-12-11 Miguel de Icaza <miguel@ximian.com>
5050 * expression.cs: Remove reducer for binary expressions, it can not

5119 * statement.cs (Using.EmitLocalVariableDecls): Split the
5120 localvariable handling of the using statement.
5122 (Block.EmitMeta): Keep track of variable count across blocks. We
5123 were reusing slots on separate branches of blocks.
5125 (Try.Emit): Emit the general code block, we were not emitting it.
5127 Check the type of the declaration to be an IDisposable or
5128 something that can be implicity converted to it.

5151 properly generate the overflow opcodes.
5153 2001-12-04 Miguel de Icaza <miguel@ximian.com>
5155 * statement.cs: The correct type for the EmptyExpression is the
5156 element_type, not the variable type. Ravi pointed this out.
5158 2001-12-04 Ravi Pratap <ravi@ximian.com>
5160 * class.cs (Method::Define): Handle PInvoke methods specially
5161 by using DefinePInvokeMethod instead of the usual one.
5163 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
5164 above to do the task of extracting information and defining the method.
5166 2001-12-04 Ravi Pratap <ravi@ximian.com>

5253 * enum.cs (LookupEnumValue): Re-write various bits, return an object value
5254 instead of a Literal - much easier.
5256 (EnumInTransit): Remove - utterly useless :-)
5258 (Populate): Re-write bits - remove duplicate code etc. The code is much neater now.
5260 * expression.cs (MemberLookup): Cope with user-defined enums when they are in transit.

5360 (Bounds): Make it a hashtable to prevent the same dimension being
5361 recorded for every element in that dimension.

5410 2001-11-22 Miguel de Icaza <miguel@ximian.com>
5412 * statement.cs (If.Emit): Fix a bug that generated incorrect code
5413 on If. Basically, we have to return `true' (ie, we do return to

5420 (Cast.Cast): Take an expression as the target type.
5422 * cs-parser.jay (cast_expression): Remove old hack that only
5423 allowed a limited set of types to be handled. Now we take a
5424 unary_expression and we resolve to a type during semantic
5427 Use the grammar productions from Rhys to handle casts (this is
5428 not complete like Rhys syntax yet, we fail to handle that corner
5429 case that C# has regarding (-x), but we will get there.
5431 2001-11-22 Ravi Pratap <ravi@ximian.com>
5433 * class.cs (EmitFieldInitializer): Take care of the case when we have a
5434 field which is an array type.

5440 (everywhere): Use the above appropriately.
5442 * cs-parser.jay (for_statement): Update for array initialization while
5443 declaring variables.
5445 * ecore.cs : The error message was correct, it's the variable's names that

5448 (MemberAccess::DoResolve): Fix the code which handles Enum literals to set
5449 the correct type etc.
5451 (ConvertExplicit): Handle Enum types by examining the underlying type.
5453 2001-11-21 Ravi Pratap <ravi@ximian.com>

5466 BindingFlags.Instance as well
5468 * ecore.cs (Expression.TryImplicitIntConversion): Wrap the result
5469 implicit int literal conversion in an empty cast so that we
5470 propagate the right type upstream.

5473 (Expression.ConvertExplicit): Add explicit type conversions done
5476 (Expression.ImplicitNumericConversion): Oops, forgot to test for
5477 the target type before applying the implicit LongLiterals to ULong
5480 2001-11-21 Miguel de Icaza <miguel@ximian.com>
5482 * cs-parser.jay (for_statement): Reworked the way For works: now
5483 we declare manually any variables that are introduced in
5484 for_initializer to solve the problem of having out-of-band code
5485 emition (that is what got for broken).
5487 (declaration_statement): Perform the actual variable declaration
5488 that used to be done in local_variable_declaration here.
5490 (local_variable_declaration): Do not declare anything, just pass
5491 the information on a DictionaryEntry
5493 2001-11-20 Ravi Pratap <ravi@ximian.com>
5495 * expression.cs (ArrayCreation::CheckIndices): The story continues :-) Complete

5558 we can use this elsewhere.
5560 * statement.cs: Finish implementation of foreach for single
5563 * cs-parser.jay: Use an out-of-band stack to pass information
5564 around, I wonder why I need this.
5566 foreach_block: Make the new foreach_block the current_block.
5568 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
5569 function used to return a static Parameters structure. Used for
5570 empty parameters, as those are created very frequently.
5572 * cs-parser.jay, class.cs: Use GetEmptyReadOnlyParameters
5574 2001-11-15 Ravi Pratap <ravi@ximian.com>
5576 * interface.cs : Default modifier is private, not public. The
5577 make verify test passes again.
5579 2001-11-15 Ravi Pratap <ravi@ximian.com>
5581 * support.cs (ReflectionParameters): Fix logic to determine
5582 whether the last parameter is a params one. Test 9 passes again.

5588 of $$ to get at the location.
5590 (indexer_declaration): Similar stuff.
5594 * class.cs (Property): Register parameters for the Get and Set methods

5615 2001-11-09 Miguel de Icaza <miguel@ximian.com>
5617 * enum.cs (Enum.Emit): Delay the lookup of loc until we run into
5618 an error. This removes the lookup from the critical path.

5632 and cons_param_array_attribute (ConstructorInfo for
5633 ParamArrayAttribute).,
5635 * codegen.cs: Emit the return using the `Return' statement, that
5636 way we can report the error correctly for missing return values.
5638 * class.cs (Method.Emit): Clean up.
5640 * expression.cs (Argument.Resolve): Take another argument: the
5641 location where this argument is used. Notice that this is not
5642 part of the "Argument" class as to reduce the size of the
5643 structure (we know the approximate location anyways).
5645 Test if the argument is a variable-reference, if not, then
5646 complain with a 206.
5648 (Argument.Emit): Emit addresses of variables.
5650 (Argument.FullDesc): Simplify.
5652 (Invocation.DoResolve): Update for Argument.Resolve.
5654 (ElementAccess.DoResolve): ditto.

5677 2001-11-13 Miguel de Icaza <miguel@ximian.com>
5679 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
5680 enumerations that are used in heavily used structures derive from
5681 byte in a laughable and pathetic attempt to reduce memory usage.
5682 This is the kind of pre-optimzations that you should not do at
5683 home without adult supervision.
5685 * expression.cs (UnaryMutator): New class, used to handle ++ and
5686 -- separatedly from the other unary operators. Cleans up the
5687 code, and kills the ExpressionStatement dependency in Unary.
5689 (Unary): Removed `method' and `Arguments' from this class, making
5690 it smaller, and moving it all to SimpleCall, so I can reuse this
5691 code in other locations and avoid creating a lot of transient data
5692 strucutres when not required.
5694 * cs-parser.jay: Adjust for new changes.
5696 2001-11-11 Miguel de Icaza <miguel@ximian.com>
5698 * enum.cs (Enum.Populate): If there is a failure during

6451 * delegate.cs (Populate): Take TypeContainer argument.
6452 Implement bits to define the Invoke method. However, I still haven't figured out
6453 how to take care of the native int bit :-(
6455 * cs-parser.jay (delegate_declaration): Fixed the bug that I had introduced :-)
6456 Qualify the name of the delegate, not its return type !
6458 * expression.cs (ImplicitReferenceConversion): Implement guts of implicit array
6461 (StandardConversionExists): Checking for array types turns out to be recursive.
6463 (ConvertReferenceExplicit): Implement array conversion.
6465 (ExplicitReferenceConversionExists): New method to determine precisely that :-)
6467 2001-10-12 Ravi Pratap <ravi@ximian.com>
6469 * cs-parser.jay (delegate_declaration): Store the fully qualified
6470 name as it is a type declaration.
6472 * delegate.cs (ReturnType, Name): Rename members to these. Make them
6475 (DefineDelegate): Renamed from Define. Does the same thing essentially,
6476 as TypeContainer::DefineType.
6478 (Populate): Method in which all the definition of the various methods (Invoke)
6481 (Emit): Emit any code, if necessary. I am not sure about this really, but let's
6484 (CloseDelegate): Finally creates the delegate.
6486 * class.cs (TypeContainer::DefineType): Update to define delegates.
6487 (Populate, Emit and CloseType): Do the same thing here too.
6489 * rootcontext.cs (ResolveTree, PopulateTypes, EmitCode, CloseTypes): Include
6490 delegates in all these operations.
6492 2001-10-14 Miguel de Icaza <miguel@ximian.com>
6494 * expression.cs: LocalTemporary: a new expression used to
6495 reference a temporary that has been created.
6497 * assign.cs: Handle PropertyAccess back here, so that we can
6498 provide the proper semantic access to properties.
6500 * expression.cs (Expression::ConvertReferenceExplicit): Implement
6501 a few more explicit conversions.
6503 * modifiers.cs: `NEW' modifier maps to HideBySig.
6505 * expression.cs (PropertyExpr): Make this into an
6506 ExpressionStatement, and support the EmitStatement code path.
6508 Perform get/set error checking, clean up the interface.
6510 * assign.cs: recognize PropertyExprs as targets, and if so, turn
6511 them into toplevel access objects.
6513 2001-10-12 Miguel de Icaza <miguel@ximian.com>
6515 * expression.cs: PropertyExpr::PropertyExpr: use work around the
6518 * typemanager.cs: Keep track here of our PropertyBuilders again to
6519 work around lameness in SRE.
6521 2001-10-11 Miguel de Icaza <miguel@ximian.com>
6523 * expression.cs (LValue::LValueResolve): New method in the
6524 interface, used to perform a second resolution pass for LValues.
6526 (This::DoResolve): Catch the use of this in static methods.
6528 (This::LValueResolve): Implement.
6530 (This::Store): Remove warning, assigning to `this' in structures
6533 (Invocation::Emit): Deal with invocation of
6534 methods on value types. We need to pass the address to structure
6535 methods rather than the object itself. (The equivalent code to
6536 emit "this" for structures leaves the entire structure on the
6537 stack instead of a pointer to it).
6539 (ParameterReference::DoResolve): Compute the real index for the
6540 argument based on whether the method takes or not a `this' pointer
6541 (ie, the method is static).
6543 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store
6544 value types returned from functions when we need to invoke a
6545 method on the sturcture.
6548 2001-10-11 Ravi Pratap <ravi@ximian.com>
6550 * class.cs (TypeContainer::DefineType): Method to actually do the business of
6551 defining the type in the Modulebuilder or Typebuilder. This is to take
6552 care of nested types which need to be defined on the TypeBuilder using
6555 (TypeContainer::GetClassBases): Implement. Essentially the code from the
6556 methods in RootContext, only ported to be part of TypeContainer.
6558 (TypeContainer::GetInterfaceOrClass): Ditto.
6560 (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
6562 * interface.cs (Interface::DefineInterface): New method. Does exactly
6563 what RootContext.CreateInterface did earlier, only it takes care of nested types
6566 (Interface::GetInterfaces): Move from RootContext here and port.
6568 (Interface::GetInterfaceByName): Same here.
6570 * rootcontext.cs (ResolveTree): Re-write.

6575 (TypeContainer::Emit): Emit nested members too.
6577 * typemanager.cs (AddUserType): Do not make use of the FullName property,
6578 instead just use the name argument passed in as it is already fully
6581 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
6582 to TypeContainer mapping to see if a type is user-defined.
6584 * class.cs (TypeContainer::CloseType): Implement.
6586 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
6587 the default constructor.
6589 (TypeContainer::Populate): Fix minor bug which led to creating default constructors
6592 (Constructor::IsDefault): Fix up logic to determine if it is the default constructor
6594 * interface.cs (CloseType): Create the type here.
6596 * rootcontext.cs (CloseTypes): Re-write to recursively close types by running through
6599 Remove all the methods which are now in TypeContainer.
6601 2001-10-10 Ravi Pratap <ravi@ximian.com>
6603 * delegate.cs (Define): Re-write bits to define the delegate
6606 2001-10-10 Miguel de Icaza <miguel@ximian.com>
6608 * makefile: Renamed the compiler to `mcs.exe' instead of compiler.exe
6610 * expression.cs (ImplicitReferenceConversion): handle null as well
6611 as a source to convert to any reference type.
6613 * statement.cs (Return): Perform any implicit conversions to
6614 expected return type.
6616 Validate use of return statement.
6618 * codegen.cs (EmitContext): Pass the expected return type here.
6620 * class.cs (Method, Constructor, Property): Pass expected return
6621 type to EmitContext.
6623 2001-10-09 Miguel de Icaza <miguel@ximian.com>
6625 * expression.cs: Make DoResolve take an EmitContext instead of a
6628 Replaced `l' and `location' for `loc', for consistency.
6630 (Error, Warning): Remove unneeded Tc argument.
6632 * assign.cs, literal.cs, constant.cs: Update to new calling
6635 * codegen.cs: EmitContext now contains a flag indicating whether
6636 code is being generated in a static method or not.
6638 * cs-parser.jay: DecomposeQI, new function that replaces the old
6639 QualifiedIdentifier. Now we always decompose the assembled
6640 strings from qualified_identifier productions into a group of
6643 2001-10-08 Miguel de Icaza <miguel@ximian.com>
6645 * rootcontext.cs: Deal with field-less struct types correctly now
6646 by passing the size option to Define Type.
6648 * class.cs: Removed hack that created one static field.
6650 2001-10-07 Miguel de Icaza <miguel@ximian.com>
6652 * statement.cs: Moved most of the code generation here.
6654 2001-10-09 Ravi Pratap <ravi@ximian.com>
6656 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
6659 (ElementAccess): Remove useless bits for now - keep checks as the spec
6662 2001-10-08 Ravi Pratap <ravi@ximian.com>
6664 * expression.cs (ElementAccess::DoResolve): Remove my crap code
6665 and start performing checks according to the spec.
6667 2001-10-07 Ravi Pratap <ravi@ximian.com>
6669 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
6670 rank_specifiers instead.
6672 (rank_specifiers): Change the order in which the rank specifiers are stored
6674 (local_variable_declaration): Use opt_rank_specifier instead of type_suffixes.
6676 * expression.cs (ElementAccess): Implement the LValue interface too.
6678 2001-10-06 Ravi Pratap <ravi@ximian.com>
6680 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
6681 except that user defined conversions are not included.
6683 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
6684 perform the conversion of the return type, if necessary.
6686 (New::DoResolve): Check whether we are creating an array or an object
6687 and accordingly do the needful.
6689 (New::Emit): Same here.
6691 (New::DoResolve): Implement guts of array creation.
6693 (New::FormLookupType): Helper function.
6695 2001-10-07 Miguel de Icaza <miguel@ximian.com>
6697 * codegen.cs: Removed most of the code generation here, and move the
6698 corresponding code generation bits to the statement classes.
6700 Added support for try/catch/finalize and throw.
6702 * cs-parser.jay: Added support for try/catch/finalize.
6704 * class.cs: Catch static methods having the flags override,
6705 virtual or abstract.
6707 * expression.cs (UserCast): This user cast was not really doing
6708 what it was supposed to do. Which is to be born in fully resolved
6709 state. Parts of the resolution were being performed at Emit time!
6713 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6715 * expression.cs: Implicity convert the result from UserCast.
6717 2001-10-05 Ravi Pratap <ravi@ximian.com>
6719 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
6720 prevented it from working correctly.
6722 (ConvertExplicit): Make the first try, a call to ConvertImplicitStandard, not
6723 merely ConvertImplicit.
6725 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6727 * typemanager.cs: Make the LookupTypeContainer function static,
6728 and not per-instance.
6730 * class.cs: Make static FindMembers (the one that takes a Type
6733 * codegen.cs: Add EmitForeach here.
6735 * cs-parser.jay: Make foreach a toplevel object instead of the
6736 inline expansion, as we need to perform semantic analysis on it.
6738 2001-10-05 Ravi Pratap <ravi@ximian.com>
6740 * expression.cs (Expression::ImplicitUserConversion): Rename to
6741 UserDefinedConversion.
6743 (Expression::UserDefinedConversion): Take an extra argument specifying
6744 whether we look for explicit user conversions too.
6746 (Expression::ImplicitUserConversion): Make it a call to UserDefinedConversion.

6755 * expression.cs (Cast): Record location info.
6757 (Expression::ConvertExplicit): Take location argument.
6759 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
6760 to determine if we are doing explicit conversions.
6762 (UserCast::Emit): Update accordingly.
6764 (Expression::ConvertExplicit): Report an error if everything fails.
6766 * ../errors/cs0030.cs : Add.
6768 2001-10-04 Miguel de Icaza <miguel@ximian.com>
6770 * modifiers.cs: If the ABSTRACT keyword is present, also set the
6771 virtual and newslot bits.
6773 * class.cs (TypeContainer::RegisterRequiredImplementations):
6774 Record methods we need.
6776 (TypeContainer::MakeKey): Helper function to make keys for
6777 MethodBases, since the Methodbase key is useless.
6779 (TypeContainer::Populate): Call RegisterRequiredImplementations
6780 before defining the methods.
6782 Create a mapping for method_builders_to_methods ahead of time
6783 instead of inside a tight loop.
6785 (::RequireMethods): Accept an object as the data to set into the
6786 hashtable so we can report interface vs abstract method mismatch.
6788 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6790 * report.cs: Make all of it static.
6792 * rootcontext.cs: Drop object_type and value_type computations, as
6793 we have those in the TypeManager anyways.
6795 Drop report instance variable too, now it is a global.
6797 * driver.cs: Use try/catch on command line handling.
6799 Add --probe option to debug the error reporting system with a test
6802 * report.cs: Add support for exiting program when a probe
6803 condition is reached.
6805 2001-10-03 Ravi Pratap <ravi@ximian.com>
6807 * expression.cs (Binary::DoNumericPromotions): Fix the case when
6808 we do a forcible conversion regardless of type, to check if
6809 ForceConversion returns a null.
6811 (Binary::error19): Use location to report error.
6813 (Unary::error23): Use location here too.
6815 * ../errors/cs0019.cs : Check in.
6817 * ../errors/cs0023.cs : Check in.
6819 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
6820 case of a non-null MethodInfo object with a length of 0 !
6822 (Binary::ResolveOperator): Flag error if overload resolution fails to find
6823 an applicable member - according to the spec :-)
6824 Also fix logic to find members in base types.
6826 (Unary::ResolveOperator): Same here.
6828 (Unary::report23): Change name to error23 and make first argument a TypeContainer
6829 as I was getting thoroughly confused between this and error19 :-)
6831 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
6832 (::FindMostEncompassedType): Implement.
6833 (::FindMostEncompassingType): Implement.
6834 (::StandardConversionExists): Implement.
6836 (UserImplicitCast): Re-vamp. We now need info about most specific
6837 source and target types so that we can do the necessary conversions.
6839 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
6840 mathematical union with no duplicates.
6842 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6844 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
6845 in order from base classes to child classes, so that we can in
6846 child classes look up in our parent for method names and
6847 attributes (required for handling abstract, virtual, new, override
6848 constructs: we need to instrospect our base class, and if we dont
6849 populate the classes in order, the introspection might be
6850 incorrect. For example, a method could query its parent before
6851 the parent has any methods and would determine that the parent has
6852 no abstract methods (while it could have had them)).
6854 (RootContext::CreateType): Record the order in which we define the
6857 2001-10-02 Miguel de Icaza <miguel@ximian.com>
6859 * class.cs (TypeContainer::Populate): Also method definitions can
6860 fail now, keep track of this.
6862 (TypeContainer::FindMembers): Implement support for
6863 DeclaredOnly/noDeclaredOnly flag.
6865 (Constructor::Emit) Return the ConstructorBuilder.
6867 (Method::Emit) Return the MethodBuilder.
6868 Check for abstract or virtual methods to be public.
6870 * rootcontext.cs (RootContext::CreateType): Register all the
6871 abstract methods required for the class to be complete and the
6872 interface methods that must be implemented.
6874 * cs-parser.jay: Report error 501 (method requires body if it is
6875 not marked abstract or extern).
6877 * expression.cs (TypeOf::Emit): Implement.
6879 * typemanager.cs: runtime_handle_type, new global type.
6881 * class.cs (Property::Emit): Generate code for properties.
6883 2001-10-02 Ravi Pratap <ravi@ximian.com>
6885 * expression.cs (Unary::ResolveOperator): Find operators on base type
6886 too - we now conform exactly to the spec.
6888 (Binary::ResolveOperator): Same here.
6890 * class.cs (Operator::Define): Fix minor quirk in the tests.
6892 * ../errors/cs0215.cs : Added.
6894 * ../errors/cs0556.cs : Added.
6896 * ../errors/cs0555.cs : Added.
6898 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6900 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
6901 single integer which is really efficient
6903 2001-10-01 Ravi Pratap <ravi@ximian.com>
6905 * expression.cs (Expression::ImplicitUserConversion): Use location
6906 even in the case when we are examining True operators.
6908 * class.cs (Operator::Define): Perform extensive checks to conform
6909 with the rules for operator overloading in the spec.
6911 * expression.cs (Expression::ImplicitReferenceConversion): Implement
6912 some of the other conversions mentioned in the spec.
6914 * typemanager.cs (array_type): New static member for the System.Array built-in
6917 (cloneable_interface): For System.ICloneable interface.
6919 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
6920 we start resolving the tree and populating types.
6922 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
6924 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6926 * expression.cs (Expression::ExprClassFromMemberInfo,
6927 Expression::Literalize): Create literal expressions from
6928 FieldInfos which are literals.
6930 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
6931 type casts, because they were wrong. The test suite in tests
6934 (ImplicitNumericConversion): ushort to ulong requires a widening
6937 Int32 constant to long requires widening cast as well.
6939 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
6940 for integers because the type on the stack is not i4.
6942 2001-09-30 Miguel de Icaza <miguel@ximian.com>
6944 * expression.cs (report118): require location argument.
6946 * parameter.cs: Do not dereference potential null value.
6948 * class.cs: Catch methods that lack the `new' keyword when
6949 overriding a name. Report warnings when `new' is used without
6950 anything being there to override.
6952 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
6954 * class.cs: Only add constructor to hashtable if it is non-null
6955 (as now constructors can fail on define).
6957 (TypeManager, Class, Struct): Take location arguments.
6959 Catch field instance initialization in structs as errors.
6961 accepting_filter: a new filter for FindMembers that is static so
6962 that we dont create an instance per invocation.
6964 (Constructor::Define): Catch errors where a struct constructor is
6967 * cs-parser.jay: Pass location information for various new
6970 * delegate.cs (Delegate): take a location argument.
6972 * driver.cs: Do not call EmitCode if there were problesm in the
6973 Definition of the types, as many Builders wont be there.
6975 * decl.cs (Decl::Decl): Require a location argument.
6977 * cs-tokenizer.cs: Handle properly hex constants that can not fit
6978 into integers, and find the most appropiate integer for it.
6980 * literal.cs: Implement ULongLiteral.
6982 * rootcontext.cs: Provide better information about the location of
6983 failure when CreateType fails.
6985 2001-09-29 Miguel de Icaza <miguel@ximian.com>
6987 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
6990 * expression.cs (Binary::CheckShiftArguments): Add missing type
6992 (Binary::ResolveOperator): Add type to the logical and and logical
6993 or, Bitwise And/Or and Exclusive Or code paths, it was missing
6996 (Binary::DoNumericPromotions): In the case where either argument
6997 is ulong (and most signed types combined with ulong cause an
6998 error) perform implicit integer constant conversions as well.
7000 2001-09-28 Miguel de Icaza <miguel@ximian.com>
7002 * expression.cs (UserImplicitCast): Method should always be
7004 (Invocation::BetterConversion): Simplified test for IntLiteral.
7006 (Expression::ImplicitNumericConversion): Split this routine out.
7007 Put the code that performs implicit constant integer conversions
7010 (Expression::Resolve): Become a wrapper around DoResolve so we can
7011 check eclass and type being set after resolve.
7013 (Invocation::Badness): Remove this dead function
7015 (Binary::ResolveOperator): Do not compute the expensive argumnets
7016 unless we have a union for it.
7018 (Probe::Emit): Is needs to do an isinst and then
7019 compare against null.
7021 (::CanConvert): Added Location argument. If the Location argument
7022 is null (Location.Null), then we do not report errors. This is
7023 used by the `probe' mechanism of the Explicit conversion. We do
7024 not want to generate an error for something that the user
7025 explicitly requested to be casted. But the pipeline for an
7026 explicit cast first tests for potential implicit casts.
7028 So for now, if the Location is null, it means `Probe only' to
7029 avoid adding another argument. Might have to revise this
7032 (ClassCast): New class used to type cast objects into arbitrary
7033 classes (used in Explicit Reference Conversions).
7035 Implement `as' as well.
7037 Reverted all the patches from Ravi below: they were broken:
7039 * The use of `level' as a mechanism to stop recursive
7040 invocations is wrong. That was there just to catch the
7041 bug with a strack trace but not as a way of addressing
7044 To fix the problem we have to *understand* what is going
7045 on and the interactions and come up with a plan, not
7046 just get things going.
7048 * The use of the type conversion cache that I proposed
7049 last night had an open topic: How does this work across
7050 protection domains. A user defined conversion might not
7051 be public in the location where we are applying the
7052 conversion, a different conversion might be selected
7053 (ie, private A->B (better) but public B->A (worse),
7054 inside A, A->B applies, but outside it, B->A will
7057 * On top of that (ie, even if the above is solved),
7058 conversions in a cache need to be abstract. Ie, `To
7059 convert from an Int to a Short use an OpcodeCast', not
7060 `To convert from an Int to a Short use the OpcodeCast on
7061 the variable 5' (which is what this patch was doing).
7063 2001-09-28 Ravi Pratap <ravi@ximian.com>
7065 * expression.cs (Invocation::ConversionExists): Re-write to use
7066 the conversion cache
7068 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
7069 cache all conversions done, not just user-defined ones.
7071 (Invocation::BetterConversion): The real culprit. Use ConversionExists
7072 to determine if a conversion exists instead of acutually trying to
7073 perform the conversion. It's faster too.
7075 (Expression::ConvertExplicit): Modify to use ConversionExists to check
7076 and only then attempt the implicit conversion.
7078 2001-09-28 Ravi Pratap <ravi@ximian.com>
7080 * expression.cs (ConvertImplicit): Use a cache for conversions
7081 already found. Check level of recursion and bail out if necessary.
7083 2001-09-28 Miguel de Icaza <miguel@ximian.com>
7085 * typemanager.cs (string_concat_string_string, string_concat_object_object):
7086 Export standard methods that we expect for string operations.
7088 * statement.cs (Block::UsageWarning): Track usage of variables and
7089 report the errors for not used variables.
7091 * expression.cs (Conditional::Resolve, ::Emit): Implement ?:
7094 2001-09-27 Miguel de Icaza <miguel@ximian.com>
7096 * codegen.cs: remove unnneded code
7098 * expression.cs: Removed BuiltinTypeAccess class
7100 Fix the order in which implicit conversions are
7103 The previous fixed dropped support for boxed conversions (adding a
7104 test to the test suite now)
7106 (UserImplicitCast::CanConvert): Remove test for source being null,
7107 that code is broken. We should not feed a null to begin with, if
7108 we do, then we should track the bug where the problem originates
7109 and not try to cover it up here.
7111 Return a resolved expression of type UserImplicitCast on success
7112 rather than true/false. Ravi: this is what I was talking about,
7113 the pattern is to use a static method as a "constructor" for
7116 Also, do not create arguments until the very last minute,
7117 otherwise we always create the arguments even for lookups that
7118 will never be performed.
7120 (UserImplicitCast::Resolve): Eliminate, objects of type
7121 UserImplicitCast are born in a fully resolved state.
7123 * typemanager.cs (InitCoreTypes): Init also value_type
7126 * expression.cs (Cast::Resolve): First resolve the child expression.
7128 (LValue): Add new method AddressOf to be used by
7131 Change the argument of Store to take an EmitContext instead of an
7132 ILGenerator, because things like FieldExpr need to be able to call
7133 their children expression to generate the instance code.
7135 (Expression::Error, Expression::Warning): Sugar functions for
7138 (Expression::MemberLookup): Accept a TypeContainer instead of a
7139 Report as the first argument.
7141 (Expression::ResolvePrimary): Killed. I still want to improve
7142 this as currently the code is just not right.
7144 (Expression::ResolveMemberAccess): Simplify, but it is still
7147 (Unary::Resolve): Catch errors in AddressOf operators.
7149 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
7150 index to a byte for the short-version, or the compiler will choose
7151 the wrong Emit call, which generates the wrong data.
7153 (ParameterReference::Emit, ::Store): same.
7155 (FieldExpr::AddressOf): Implement.
7157 * typemanager.cs: TypeManager: made public variable instead of
7160 * driver.cs: document --fatal.

7163 Error and Warning classes.
7165 * cs-parser.jay (member_access): Turn built-in access to types
7166 into a normal simplename
7168 2001-09-27 Ravi Pratap <ravi@ximian.com>

7171 with q being null, since this was introducing a bug.
7173 * expression.cs (ConvertImplicit): Do built-in conversions first.
7175 2001-09-27 Ravi Pratap <ravi@ximian.com>
7177 * expression.cs (UserImplicitCast::Resolve): Fix bug.
7179 2001-09-27 Ravi Pratap <ravi@ximian.com>
7181 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
7182 I had introduced long ago (what's new ?).
7184 * expression.cs (UserImplicitCast::CanConvert): Static method to do
7185 the work of all the checking.
7186 (ConvertImplicit): Call CanConvert and only then create object if necessary.
7187 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
7189 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
7190 that is the right way.
7192 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
7193 overloading resolution. Use everywhere instead of cutting and pasting code.
7195 (Binary::ResolveOperator): Use MakeUnionSet.
7197 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
7198 we have to convert to bool types. Not complete yet.
7200 2001-09-27 Miguel de Icaza <miguel@ximian.com>
7202 * typemanager.cs (TypeManager::CSharpName): support ushort.
7204 * expression.cs (Expression::TryImplicitIntConversion): Attempts
7205 to provide an expression that performsn an implicit constant int
7206 conversion (section 6.1.6).
7207 (Expression::ConvertImplicitRequired): Reworked to include
7208 implicit constant expression conversions.
7210 (Expression::ConvertNumericExplicit): Finished.
7212 (Invocation::Emit): If InstanceExpression is null, then it means
7213 that we perform a call on this.
7215 2001-09-26 Miguel de Icaza <miguel@ximian.com>
7217 * expression.cs (Unary::Emit): Remove some dead code.
7218 (Probe): Implement Resolve and Emit for `is'.
7219 (Expression::ConvertImplicitRequired): Attempt to do constant
7220 expression conversions here. Maybe should be moved to
7221 ConvertImplicit, but I am not sure.
7222 (Expression::ImplicitLongConstantConversionPossible,
7223 Expression::ImplicitIntConstantConversionPossible): New functions
7224 that tell whether is it possible to apply an implicit constant
7225 expression conversion.
7227 (ConvertNumericExplicit): Started work on explicit numeric
7230 * cs-parser.jay: Update operator constants.
7232 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs

7238 ones that the spec expects (as we are just stringizing the
7241 * expression.cs (Unary::ResolveOperator): Fix bug: Use
7242 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
7243 previous usage did only work for our methods.
7244 (Expression::ConvertImplicit): Handle decimal implicit numeric
7245 conversions as well.
7246 (Expression::InternalTypeConstructor): Used to invoke constructors
7247 on internal types for default promotions.
7249 (Unary::Emit): Implement special handling for the pre/post
7250 increment/decrement for overloaded operators, as they need to have
7251 the same semantics as the other operators.
7253 (Binary::ResolveOperator): ditto.
7254 (Invocation::ConversionExists): ditto.
7255 (UserImplicitCast::Resolve): ditto.
7257 2001-09-26 Ravi Pratap <ravi@ximian.com>
7259 * expression.cs (Unary::Emit and Binary::Emit): If we have an overloaded
7260 operator, return after emitting body. Regression tests pass again !

7274 expressions that can appear in statements, so that we can provide
7275 an alternate path to generate expression that do not leave a value
7278 (Expression::Emit, and all the derivatives): We no longer return
7279 whether a value is left on the stack or not. Every expression
7280 after being emitted leaves a single value on the stack.
7282 * codegen.cs (EmitContext::EmitStatementExpression): Use the
7283 facilties of ExpressionStatement if possible.
7285 * cs-parser.jay: Update statement_expression.

7306 (ConvertImplicit): Do user-defined conversion if it exists.
7308 2001-09-24 Miguel de Icaza <miguel@ximian.com>
7310 * assign.cs: track location.
7311 (Resolve): Use implicit conversions on assignment.

7354 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
7355 Also take an additional TypeContainer argument.
7357 * All over : Pass in TypeContainer as argument to OverloadResolve.
7359 * typemanager.cs (CSharpName): Update to check for the string type and return

7376 * typemanager.cs: declare and load enum_type, delegate_type and
7379 * expression.cs (Expression::Emit): Now emit returns a value that
7380 tells whether a value is left on the stack or not. This strategy
7381 might be reveted tomorrow with a mechanism that would address
7382 multiple assignments.
7383 (Expression::report118): Utility routine to report mismatches on
7386 (Unary::Report23): Report impossible type/operator combination
7389 (Unary::IsIncrementableNumber): Whether the type can be

7434 * expression.cs: Instead of having FIXMEs in the Resolve
7435 functions, throw exceptions so it is obvious that we are facing a
7438 * cs-parser.jay (invocation_expression): Pass Location information.
7440 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
7441 Use a basename for those routines because .NET does not like paths

7447 2001-09-19 Miguel de Icaza <miguel@ximian.com>
7449 * typemanager.cs (TypeManager::CoreLookupType): A function to make sure that we
7450 are loading the correct data types (throws an exception if not).

7453 * expression.cs (Unary::ResolveOperator): return the child
7454 expression for expressions which are just +expr.
7455 (Unary::ResolveOperator): Return negative literals for -LITERAL
7456 expressions (otherwise they are Unary {Literal}).
7457 (Invocation::Badness): Take into account `Implicit constant
7458 expression conversions'.
7460 * literal.cs (LongLiteral): Implement long literal class.
7461 (IntLiteral): export the `Value' of the intliteral.
7463 2001-09-19 Ravi Pratap <ravi@ximian.com>
7465 * expression.cs (Binary::Emit): Finally get the emission right ! Woo!
7467 * class.cs (Operator::Define): Change the methodname prefix to 'op_'
7468 instead of 'Operator'
7470 * expression.cs (Binary::ResolveOperator): Update accordingly.
7471 (Unary::Operator): Change names to 'Add' and 'Subtract' instead 'Plus'

7478 * expression.cs (Unary::Resolve): Implement.
7479 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
7480 operators are found instead of making noise ;-)
7481 (Unary::ResolveOperator): New method to do precisely the same thing which
7482 Binary::ResolveOperator does for Binary expressions.
7483 (Unary.method, .Arguments): Add.
7484 (Unary::OperName): Implement.
7485 (Unary::ForceConversion): Copy and Paste !
7487 * class.cs (Operator::Define): Fix a small bug for the case when we have
7490 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes
7491 for the inbuilt operators. Only overloading works for now ;-)
7493 2001-09-18 Miguel de Icaza <miguel@ximian.com>
7495 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
7496 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

7509 (FieldExpr::Emit): Implement.
7511 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
7512 the last instruction contains a return opcode to avoid generating
7513 the last `ret' instruction (this generates correct code, and it is
7514 nice to pass the peverify output).
7516 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
7517 initializer for static and instance variables.
7518 (Constructor::Emit): Allow initializer to be null in the case of
7519 static constructors. Only emit initializer for instance
7522 (TypeContainer::FindMembers): Return a null array if there are no
7525 Also fix the code for the MemberTypes.Method branch, as it was not
7526 scanning that for operators (or tried to access null variables before).
7528 * assign.cs (Assign::Emit): Handle instance and static fields.
7532 * driver.cs: Stop compilation if there are parse errors.
7534 * cs-parser.jay (constructor_declaration): Provide default base
7535 initializer for non-static constructors.

7537 initializers if none was specified.
7538 Catch the fact that constructors should not have parameters.
7540 * class.cs: Do not emit parent class initializers for static
7541 constructors, that should be flagged as an error.
7543 2001-09-18 Ravi Pratap <ravi@ximian.com>
7545 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
7546 Move back code into TypeContainer::Populate.

7572 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
7575 (Expression::MemberLookup): Provide a version that allows to
7576 specify the MemberTypes and BindingFlags.
7578 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
7579 so it was not fetching variable information from outer blocks.
7581 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
7582 Beforefieldinit as it was buggy.
7584 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
7587 * class.cs (Constructor::Emit): Only emit if block is not null.
7588 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
7589 deal with this by semantically definining it as if the user had
7592 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
7593 constructors as we now "emit" them at a higher level.

7596 default constructors if none was provided.
7598 (ConstructorInitializer): Add methods Resolve and Emit.
7600 * expression.cs: Cast to ConstructorInfo instead of MethodInfo

7619 * class.cs (Operator::OpType): Change names to match the ones in Binary::Operator
7620 and Unary::Operator.
7622 * cs-parser.jay (operator_declaration, CheckBinaryOperator, CheckUnaryOperator): Update
7625 * expression.cs (Binary::method): New member to hold the MethodBase for the case when
7626 we have overloaded operators.
7627 (Binary::ResolveOperator): Implement the part which does the operator overload
7630 * class.cs (Operator::Emit): Implement.
7631 (TypeContainer::Emit): Emit the operators we have too.
7633 * expression.cs (Binary::Emit): Update to emit the appropriate code for
7634 the case when we have a user-defined operator.
7636 2001-09-17 Miguel de Icaza <miguel@ximian.com>
7638 * rootcontext.cs: Fix bug: tree.Namespaces might be null.
7640 2001-09-16 Ravi Pratap <ravi@ximian.com>
7642 * class.cs (EmitStaticFieldInitializers, EmitFieldInitializers): Make public.
7643 (TypeContainer::EmitConstructor): Remove and move code into Contructor::Emit.

7666 * rootcontext.cs (IsNamespace): Fixed it :-)
7668 2001-09-14 Miguel de Icaza <miguel@ximian.com>
7670 * class.cs (TypeContainer::FindMembers): Add support for
7672 (MethodCore): New class that encapsulates both the shared aspects
7673 of a Constructor and a Method.

7677 Load System assembly as well as part of the standard library.
7679 * report.cs: Allow throwing exceptions on errors for debugging.
7681 * modifiers.cs: Do not use `parent', instead use the real type
7682 container to evaluate permission settings.
7684 * class.cs: Put Ravi's patch back in. He is right, and we will
7685 have to cope with the
7687 2001-09-14 Ravi Pratap <ravi@ximian.com>
7689 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
7690 FamORAssem, not FamANDAssem.

7694 * driver.cs: Added --parse option that only parses its input files
7697 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
7698 incorrect. IsTopLevel is not used to tell whether an object is
7699 root_types or not (that can be achieved by testing this ==
7700 root_types). But to see if this is a top-level *class* (not
7701 necessarly our "toplevel" container).
7703 2001-09-14 Ravi Pratap <ravi@ximian.com>
7705 * enum.cs (Enum::Define): Modify to call the Lookup method on the
7706 parent instead of a direct call to GetType.
7708 2001-09-14 Ravi Pratap <ravi@ximian.com>
7710 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
7711 Modifiers.TypeAttr. This should just be a call to that method.
7713 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
7714 object so that we can determine if we are top-level or not.
7716 * delegate.cs (Delegate::Define): Update call to TypeAttr method to pass in the
7719 * enum.cs (Enum::Define): Ditto.
7721 * modifiers.cs (FieldAttr): Re-write.
7723 * class.cs (TypeContainer::IsTopLevel): Change accessibility to public.
7724 (TypeContainer::HaveStaticConstructor): New property to provide access
7725 to precisely that info.
7727 * modifiers.cs (MethodAttr): Re-write.
7728 (EventAttr): Remove altogether as there seems to be no ostensible use for it.
7730 * class.cs (TypeContainer::IsTopLevel): Re-write. root_types doesn't seem to be the parent
7731 of top-level types as claimed.
7733 2001-09-13 Miguel de Icaza <miguel@ximian.com>
7735 * expression.cs (MemberLookup): Fruitless attempt to lookup
7736 constructors. Maybe I need to emit default constructors? That
7737 might be it (currently .NET emits this for me automatically).
7738 (Invocation::OverloadResolve): Cope with Arguments == null.
7739 (Invocation::EmitArguments): new function, shared by the new
7741 (Invocation::Emit): Handle static and instance methods. Emit
7742 proper call instruction for virtual or non-virtual invocations.
7743 (New::Emit): Implement.
7744 (New::Resolve): Implement.
7745 (MemberAccess:Resolve): Implement.
7746 (MethodGroupExpr::InstanceExpression): used conforming to the spec
7748 (FieldExpr::Resolve): Set type.
7750 * support.cs: Handle empty arguments.
7752 * cs-parser.jay (CompositeLookup, QualifierIdentifier,
7753 SimpleLookup): Auxiliary routines to help parse a qualifier
7756 Update qualifier_identifier rule.
7758 * codegen.cs: Removed debugging messages.
7760 * class.cs: Make this a global thing, this acts just as a "key" to
7761 objects that we might have around.
7763 (Populate): Only initialize method_builders_to_methods once.
7765 * expression.cs (PropertyExpr): Initialize type from the
7768 * codegen.cs (EmitContext::EmitBoolExpression): Use propper
7769 Resolve pattern. Attempt to implicitly convert value to boolean.
7772 * expression.cs: Set the type for the int32/int32 argument case.
7773 (Binary::ResolveOperator): Set the return type to boolean for
7774 comparission operators
7776 * typemanager.cs: Remove debugging print code.
7778 (Invocation::Resolve): resolve type.
7780 * class.cs: Allocate a MemberInfo of the correct size, as the code
7781 elsewhere depends on the test to reflect the correct contents.
7783 (Method::) Keep track of parameters, due to System.Reflection holes
7785 (TypeContainer::Populate): Keep track of MethodBuilders to Method
7788 (TypeContainer::FindMembers): Use ArrayList and then copy an array
7789 of the exact size and return that.
7791 (Class::LookupMethodByBuilder): New function that maps
7792 MethodBuilders to its methods. Required to locate the information
7793 on methods because System.Reflection bit us again.

8113 will is used during the tree rewriting as we resolve them during

8240 * class.cs (Property): Revamp to use the convention of making fields readonly.

8289 and re-write the code in the actions to extract the specific and
8290 general catch clauses by being a little smart ;-)
8292 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
8293 Hooray, try and catch statements parse fine !

8297 * statement.cs (Block::GetVariableType): Fix logic to extract the type
8298 string from the hashtable of variables.

8351 instead of ignoring the rank_specifiers.
8352 (expression_list): Implement to collect the expressions

8356 (array_initializer): Make it a list of variable_initializers
8357 (opt_array_initializer): Modify accordingly.

8379 types after we have populated the type manager with the user

8394 beginning, will continue tomorrow with more touches of polish. We

8398 * gen-treedump.cs: Bug fix, use s.Increment here instead of
8401 * codegen.cs (EmitContext): New struct, used during code
8402 emission to keep a context. Most of the code generation will be
8405 * cs-parser.jay: Add embedded blocks to the list of statements of
8406 this block. So code generation proceeds in a top down fashion.
8408 2001-08-23 Miguel de Icaza <miguel@ximian.com>
8410 * statement.cs: Add support for multiple child blocks.
8412 2001-08-22 Miguel de Icaza <miguel@ximian.com>

8415 Block of code given a TypeContainer and its ILGenerator.
8417 * statement.cs (Block): Standard public readonly optimization.
8418 (Block::Block constructors): Link children.
8419 (Block::Child): Child Linker.
8420 (Block::EmitVariables): Emits IL variable declarations.
8422 * class.cs: Drop support for MethodGroups here, delay until
8424 (Method::): Applied the same simplification that I did before, and
8425 move from Properties to public readonly fields.
8426 (Method::ParameterTypes): Returns the parameter types for the
8427 function, and implements a cache that will be useful later when I
8428 do error checking and the semantic analysis on the methods is
8430 (Constructor::GetCallingConvention): Renamed from CallingConvetion
8431 and made a method, optional argument tells whether this is a class
8432 or a structure to apply the `has-this' bit.
8433 (Method::GetCallingConvention): Implement, returns the calling
8435 (Method::Define): Defines the type, a second pass is performed
8436 later to populate the methods.
8438 (Constructor::ParameterTypes): implement a cache similar to the
8439 one on Method::ParameterTypes, useful later when we do semantic
8442 (TypeContainer::EmitMethod): New method. Emits methods.
8444 * expression.cs: Removed MethodGroup class from here.
8446 * parameter.cs (Parameters::GetCallingConvention): new method.

8453 (Constructor::CallingConvention): Returns the calling convention.
8454 (Constructor::ParameterTypes): Returns the constructor parameter
8457 (TypeContainer::AddConstructor): Keep track of default constructor
8458 and the default static constructor.
8460 (Constructor::) Another class that starts using `public readonly'
8461 instead of properties.
8463 (Constructor::IsDefault): Whether this is a default constructor.
8465 (Field::) use readonly public fields instead of properties also.
8467 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
8468 track of static constructors; If none is used, turn on
8469 BeforeFieldInit in the TypeAttributes.
8471 * cs-parser.jay (opt_argument_list): now the return can be null
8472 for the cases where there are no arguments.
8474 (constructor_declarator): If there is no implicit `base' or
8475 `this', then invoke the default parent constructor.
8477 * modifiers.cs (MethodAttr): New static function maps a set of
8478 modifiers flags into a MethodAttributes enum
8479 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
8480 MethodAttr, TypeAttr to represent the various mappings where the
8482 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
8484 2001-08-19 Miguel de Icaza <miguel@ximian.com>
8486 * parameter.cs (GetParameterInfo): Fix bug where there would be no
8489 * interface.cs (PopulateIndexer): Implemented the code generator
8490 for interface indexers.
8492 2001-08-17 Miguel de Icaza <miguel@ximian.com>
8494 * interface.cs (InterfaceMemberBase): Now we track the new status
8497 (PopulateProperty): Implement property population. Woohoo! Got
8498 Methods and Properties going today.
8500 Removed all the properties for interfaces, and replaced them with
8501 `public readonly' fields.
8503 2001-08-16 Miguel de Icaza <miguel@ximian.com>
8505 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
8506 initialize their hashtables/arraylists only when they are needed
8507 instead of doing this always.
8509 * parameter.cs: Handle refs and out parameters.
8511 * cs-parser.jay: Use an ArrayList to construct the arguments
8512 instead of the ParameterCollection, and then cast that to a
8515 * parameter.cs: Drop the use of ParameterCollection and use
8516 instead arrays of Parameters.
8518 (GetParameterInfo): Use the Type, not the Name when resolving
8521 2001-08-13 Miguel de Icaza <miguel@ximian.com>
8523 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
8524 and instead use public readonly fields.
8526 * class.cs: Put back walking code for type containers.
8528 2001-08-11 Miguel de Icaza <miguel@ximian.com>
8530 * class.cs (MakeConstant): Code to define constants.
8532 * rootcontext.cs (LookupType): New function. Used to locate types
8535 2001-08-08 Miguel de Icaza <miguel@ximian.com>
8537 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
8538 this System.Reflection code is. Kudos to Microsoft
8540 * typemanager.cs: Implement a type cache and avoid loading all
8541 types at boot time. Wrap in LookupType the internals. This made
8542 the compiler so much faster. Wow. I rule!
8544 * driver.cs: Make sure we always load mscorlib first (for
8545 debugging purposes, nothing really important).
8547 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
8548 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
8550 * rootcontext.cs: Lookup types on their namespace; Lookup types
8551 on namespaces that have been imported using the `using' keyword.
8553 * class.cs (TypeContainer::TypeAttr): Virtualize.
8554 (Class::TypeAttr): Return attributes suitable for this bad boy.
8555 (Struct::TypeAttr): ditto.
8556 Handle nested classes.
8557 (TypeContainer::) Remove all the type visiting code, it is now
8558 replaced with the rootcontext.cs code
8560 * rootcontext.cs (GetClassBases): Added support for structs.
8562 2001-08-06 Miguel de Icaza <miguel@ximian.com>
8564 * interface.cs, statement.cs, class.cs, parameter.cs,
8565 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
8566 Drop use of TypeRefs, and use strings instead.
8568 2001-08-04 Miguel de Icaza <miguel@ximian.com>
8572 * class.cs (Struct::Struct): set the SEALED flags after
8573 checking the modifiers.
8574 (TypeContainer::TypeAttr): new property, returns the
8575 TypeAttributes for a class.
8577 * cs-parser.jay (type_list): Oops, list production was creating a
8578 new list of base types.
8580 * rootcontext.cs (StdLib): New property.
8581 (GetInterfaceTypeByName): returns an interface by type name, and
8582 encapsulates error handling here.
8583 (GetInterfaces): simplified.
8584 (ResolveTree): Encapsulated all the tree resolution here.
8585 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
8588 * driver.cs: Add support for --nostdlib, to avoid loading the
8590 (Main): Do not put tree resolution here.
8592 * rootcontext.cs: Beginning of the class resolution.
8594 2001-08-03 Miguel de Icaza <miguel@ximian.com>
8596 * rootcontext.cs: Provide better error reporting.
8598 * cs-parser.jay (interface_base): set our $$ to be interfaces.
8600 * rootcontext.cs (CreateInterface): Handle the case where there
8601 are no parent interfaces.
8603 (CloseTypes): Routine to flush types at the end.
8604 (CreateInterface): Track types.
8605 (GetInterfaces): Returns an array of Types from the list of
8608 * typemanager.c (AddUserType): Mechanism to track user types (puts
8609 the type on the global type hash, and allows us to close it at the
8612 2001-08-02 Miguel de Icaza <miguel@ximian.com>
8614 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
8615 RecordInterface instead.
8617 * cs-parser.jay: Updated to reflect changes above.
8619 * decl.cs (Definition): Keep track of the TypeBuilder type that
8620 represents this type here. Not sure we will use it in the long
8621 run, but wont hurt for now.
8623 * driver.cs: Smaller changes to accomodate the new code.
8625 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
8628 * rootcontext.cs (CreateInterface): New method, used to create
8629 the System.TypeBuilder type for interfaces.
8630 (ResolveInterfaces): new entry point to resolve the interface
8632 (CodeGen): Property, used to keep track of the code generator.
8634 2001-07-26 Miguel de Icaza <miguel@ximian.com>
8636 * cs-parser.jay: Add a second production for delegate_declaration
8639 (enum_body): Put an opt_comma here instead of putting it on
8640 enum_body or enum_member_declarations so we can handle trailing
8641 commas on enumeration members. Gets rid of a shift/reduce.
8643 (type_list): Need a COMMA in the middle.
8645 (indexer_declaration): Tell tokenizer to recognize get/set
8647 * Remove old targets.
8649 * Re-add the parser target.
8651 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8653 * cs-parser.jay: Add precendence rules for a number of operators
8654 ot reduce the number of shift/reduce conflicts in the grammar.
8656 2001-07-17 Miguel de Icaza <miguel@ximian.com>
8658 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
8661 Get rid of old crufty code.
8663 * rootcontext.cs: Use this to keep track of the parsed
8664 representation and the defined types available to the program.
8666 * gen-treedump.cs: adjust for new convention.
8668 * type.cs: Split out the type manager, and the assembly builder
8671 * typemanager.cs: the type manager will live here now.
8673 * cil-codegen.cs: And the code generator here.
8675 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
8677 * makefile: Fixed up for easy making.
8679 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8681 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
8684 (unary_expression): Expand pre_increment_expression and
8685 post_decrement_expression to reduce a shift/reduce.
8687 2001-07-11 Simon Cozens
8689 * cs-tokenizer.cs: Hex numbers should begin with a 0.
8691 Improve allow_keyword_as_indent name.
8693 2001-06-19 Miguel de Icaza <miguel@ximian.com>
8695 * Adjustments for Beta2.
8697 2001-06-13 Miguel de Icaza <miguel@ximian.com>
8699 * decl.cs: Added `Define' abstract method.
8700 (InTransit): new property, used to catch recursive definitions.
8702 * interface.cs: Implement `Define'.
8704 * modifiers.cs: Map Modifiers.constants to
8705 System.Reflection.TypeAttribute flags.
8707 * class.cs: Keep track of types and user-defined types.
8708 (BuilderInit): New method for creating an assembly
8709 (ResolveType): New function to launch the resolution process, only
8710 used by interfaces for now.
8712 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
8713 that are inserted into the name space.
8715 2001-06-08 Miguel de Icaza <miguel@ximian.com>
8717 * ARGH. I have screwed up my tree so many times due to the use of
8718 rsync rather than using CVS. Going to fix this at once.
8720 * driver.cs: Objetify driver. Load assemblies, use assemblies to
8723 2001-06-07 Miguel de Icaza <miguel@ximian.com>
8725 * Experiment successful: Use System.Type rather that our own
8728 2001-05-25 Miguel de Icaza <miguel@ximian.com>
8730 * cs-parser.jay: Removed nsAliases from here.
8732 Use new namespaces, handle `using XXX;'
8734 * namespace.cs: Reimplemented namespace handling, use a recursive
8735 definition of the class. Now we can keep track of using clauses
8736 and catch invalid using clauses.
8738 2001-05-24 Miguel de Icaza <miguel@ximian.com>
8740 * gen-treedump.cs: Adapted for all the renaming.
8742 * expression.cs (Expression): this class now has a Type property
8743 which returns an expression Type.
8745 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
8746 `Type', as this has a different meaning now in the base
8748 2001-05-22 Miguel de Icaza <miguel@ximian.com>
8750 * interface.cs, class.cs: Removed from all the sources the
8751 references to signature computation, as we can not do method
8752 signature computation during the parsing time, as we are not
8753 trying to solve at that point distinguishing:
8757 void a (NS.Blah x) {}
8760 Which depending on the context might be valid or not, as we do not
8761 know if Blah is the same thing as NS.Blah at that point.
8763 * Redid everything so the code uses TypeRefs now instead of
8764 Types. TypeRefs are just temporary type placeholders, that need
8765 to be resolved. They initially have a pointer to a string and the
8766 current scope in which they are used. This is used later by the
8767 compiler to resolve the reference to an actual Type.
8769 * DeclSpace is no longer a CIR.Type, and neither are
8770 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
8771 are all DeclSpaces, but no Types.
8773 * type.cs (TypeRefManager): This implements the TypeRef manager,
8774 which keeps track of all the types that need to be resolved after
8775 the parsing has finished.
8777 2001-05-13 Miguel de Icaza <miguel@ximian.com>
8779 * ARGH. We are going to have to store `foreach' as a class rather
8780 than resolving it, as we need to verify error 1579 after name
8781 resolution. *OR* we could keep a flag that says `This request to
8782 IEnumerator comes from a foreach statement' which we can then use
8783 to generate the error.
8785 2001-05-10 Miguel de Icaza <miguel@ximian.com>
8787 * class.cs (TypeContainer.AddMethod): we now add methods to the
8788 MethodGroup instead of the method hashtable.
8790 * expression.cs: Add MethodGroup abstraction, which gets us one
8791 step closer to the specification in the way we handle method
8794 * cs-parser.jay (primary_expression): qualified_identifier now
8795 tried to match up an identifier to a local variable reference or
8796 to a parameter reference.
8798 current_local_parameters is now a parser global variable that
8799 points to the current parameters for the block, used during name
8802 (property_declaration): Now creates an implicit `value' argument to
8805 2001-05-09 Miguel de Icaza <miguel@ximian.com>
8807 * parameter.cs: Do not use `param' arguments as part of the
8808 signature, per the spec.
8810 2001-05-08 Miguel de Icaza <miguel@ximian.com>
8812 * decl.cs: Base class for classes, structs and interfaces. This
8813 is the "Declaration Space"
8815 * cs-parser.jay: Use CheckDef for checking declaration errors
8816 instead of having one on each function.
8818 * class.cs: Factor out some code for handling error handling in
8819 accordance to the "Declarations" section in the "Basic Concepts"
8820 chapter in the ECMA C# spec.
8822 * interface.cs: Make all interface member classes derive from
8823 InterfaceMemberBase.
8825 2001-05-07 Miguel de Icaza <miguel@ximian.com>
8827 * Many things: all interfaces are parsed and generated in
8828 gen-treedump. Support for member variables, constructors,
8829 destructors, properties, constants is there.
8831 Beginning of the IL backend, but very little done, just there for
8834 2001-04-29 Miguel de Icaza <miguel@ximian.com>
8836 * cs-parser.jay: Fix labeled statement.
8838 * cs-tokenizer.cs (escape): Escape " and ' always.
8839 ref_line, ref_name: keep track of the line/filename as instructed
8840 by #line by the compiler.
8843 2001-04-27 Miguel de Icaza <miguel@ximian.com>
8845 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
8846 to match the values in System.CodeDOM.
8848 Divid renamed to Divide.
8850 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
8852 (Statements.set): remove.
8854 * System.CodeDOM/CodeCatchClause.cs: always have a valid
8857 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
8858 falseStatements always have valid values.
8860 * cs-parser.jay: Use System.CodeDOM now.
