1 2002-08-23 Martin Baulig <martin@gnome.org>
3 * codegen.cs (CodeGen.InitializeSymbolWriter): Abort if we can't
4 find the symbol writer.
6 * driver.cs: csc also allows the arguments to /define being
7 separated by commas, not only by semicolons.
9 2002-08-23 Martin Baulig <martin@gnome.org>
11 * interface.cs (Interface.GetMembers): Added static check for events.
13 2002-08-15 Martin Baulig <martin@gnome.org>
15 * class.cs (MethodData.EmitDestructor): In the Expression.MemberLookup
16 call, use ec.ContainerType.BaseType as queried_type and invocation_type.
18 * ecore.cs (Expression.MemberLookup): Added documentation and explained
19 why the MethodData.EmitDestructor() change was necessary.
21 2002-08-20 Martin Baulig <martin@gnome.org>
23 * class.cs (TypeContainer.FindMembers): Added static check for events.
25 * decl.cs (MemberCache.AddMembers): Handle events like normal members.
27 * typemanager.cs (TypeHandle.GetMembers): When queried for events only,
28 use Type.GetEvents(), not Type.FindMembers().
30 2002-08-20 Martin Baulig <martin@gnome.org>
32 * decl.cs (MemberCache): Added a special method cache which will
33 be used for method-only searched. This ensures that a method
34 search will return a MethodInfo with the correct ReflectedType for
37 2002-08-20 Martin Baulig <martin@gnome.org>
39 * decl.cs (DeclSpace.FindMembers): Made this public.
41 2002-08-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
43 * delegate.cs: fixed build on windows.
44 [FIXME: Filed as bug #29150: MCS must report these errors.]
46 2002-08-19 Ravi Pratap <ravi@ximian.com>
48 * ecore.cs (StandardConversionExists): Return a false
49 if we are trying to convert the void type to anything else
50 since that is not allowed.
52 * delegate.cs (DelegateInvocation.DoResolve): Ensure that
53 we flag error 70 in the event an event is trying to be accessed
54 directly from outside the declaring type.
56 2002-08-20 Martin Baulig <martin@gnome.org>
58 * typemanager.cs, decl.cs: Moved MemberList, IMemberContainer and
59 MemberCache from typemanager.cs to decl.cs.
61 2002-08-19 Martin Baulig <martin@gnome.org>
63 * class.cs (TypeContainer): Implement IMemberContainer.
64 (TypeContainer.DefineMembers): Create the MemberCache.
65 (TypeContainer.FindMembers): Do better BindingFlags checking; only
66 return public members if BindingFlags.Public was given, check
67 whether members are static.
69 2002-08-16 Martin Baulig <martin@gnome.org>
71 * decl.cs (DeclSpace.Define): Splitted this in Define and
72 DefineMembers. DefineMembers is called first and initializes the
75 * rootcontext.cs (RootContext.DefineMembers): New function. Calls
76 DefineMembers() on all our DeclSpaces.
78 * class.cs (TypeContainer.Define): Moved all code to DefineMembers(),
79 but call DefineMembers() on all nested interfaces. We call their
80 Define() in our new Define() function.
82 * interface.cs (Interface): Implement IMemberContainer.
83 (Interface.Define): Moved all code except the attribute stuf to
85 (Interface.DefineMembers): Initialize the member cache.
87 * typemanager.cs (IMemberFinder): Removed this interface, we don't
88 need this anymore since we can use MemberCache.FindMembers directly.
90 2002-08-19 Martin Baulig <martin@gnome.org>
92 * typemanager.cs (MemberCache): When creating the cache for an
93 interface type, add all inherited members.
94 (TypeManager.MemberLookup_FindMembers): Changed `ref bool searching'
95 to `out bool used_cache' and documented it.
96 (TypeManager.MemberLookup): If we already used the cache in the first
97 iteration, we don't need to do the interfaces check.
99 2002-08-19 Martin Baulig <martin@gnome.org>
101 * decl.cs (DeclSpace.FindMembers): New abstract method. Moved this
102 here from IMemberFinder and don't implement this interface anymore.
103 (DeclSpace.MemberCache): Moved here from IMemberFinder.
105 * typemanager.cs (IMemberFinder): This interface is now only used by
106 classes which actually support the member cache.
107 (TypeManager.builder_to_member_finder): Renamed to builder_to_declspace
108 since we only put DeclSpaces into this Hashtable.
109 (MemberLookup_FindMembers): Use `builder_to_declspace' if the type is
110 a dynamic type and TypeHandle.GetTypeHandle() otherwise.
112 2002-08-16 Martin Baulig <martin@gnome.org>
114 * typemanager.cs (ICachingMemberFinder): Removed.
115 (IMemberFinder.MemberCache): New property.
116 (TypeManager.FindMembers): Merged this with RealFindMembers().
117 This function will never be called from TypeManager.MemberLookup()
118 so we can't use the cache here, just the IMemberFinder.
119 (TypeManager.MemberLookup_FindMembers): Check whether the
120 IMemberFinder has a MemberCache and call the cache's FindMembers
122 (MemberCache): Rewrote larger parts of this yet another time and
125 2002-08-15 Miguel de Icaza <miguel@ximian.com>
127 * driver.cs (LoadArgs): Support quoting.
129 (Usage): Show the CSC-like command line arguments.
131 Improved a few error messages.
133 2002-08-15 Martin Baulig <martin@gnome.org>
135 * typemanager.cs (IMemberContainer.Type): New property.
136 (IMemberContainer.IsInterface): New property.
138 The following changes are conditional to BROKEN_RUNTIME, which is
139 defined at the top of the file.
141 * typemanager.cs (MemberCache.MemberCache): Don't add the base
142 class'es members, but add all members from TypeHandle.ObjectType
143 if we're an interface.
144 (MemberCache.AddMembers): Set the Declared flag if member.DeclaringType
146 (MemberCache.CacheEntry.Container): Removed this field.
147 (TypeHandle.GetMembers): Include inherited members.
149 2002-08-14 Gonzalo Paniagua Javier <gonzalo@ximian.com>
151 * typemanager.cs: fixed compilation and added a comment on a field that
154 2002-08-15 Martin Baulig <martin@gnome.org>
156 * class.cs (ConstructorInitializer.Resolve): In the
157 Expression.MemberLookup call, use the queried_type as
160 * typemanager.cs (IMemberContainer.GetMembers): Removed the `bool
161 declared' attribute, it's always true.
162 (IMemberContainer.Parent, IMemberContainer.Name): New properties.
163 (TypeManager.MemberLookup_FindMembers): [FIXME FIXME FIXME] Added
164 temporary wrapper for FindMembers which tells MemberLookup whether
165 members from the base classes are included in the return value.
166 This will go away soon.
167 (TypeManager.MemberLookup): Use this temporary hack here; once the
168 new MemberCache is completed, we don't need to do the DeclaredOnly
169 looping here anymore since the MemberCache will take care of this.
170 (TypeManager.IsSubclassOrNestedChildOf): Allow `type == parent'.
171 (MemberCache): When creating the MemberCache for a class, get
172 members from the current class and all its base classes.
173 (MemberCache.CacheEntry.Container): New field. This is a
174 temporary hack until the Mono runtime is fixed to distinguish
175 between ReflectedType and DeclaringType. It allows us to use MCS
176 with both the MS runtime and the unfixed Mono runtime without
177 problems and without accecting performance.
178 (MemberCache.SearchMembers): The DeclaredOnly looping from
179 TypeManager.MemberLookup is now done here.
181 2002-08-14 Martin Baulig <martin@gnome.org>
183 * statement.cs (MyStructInfo.MyStructInfo): Don't call
184 Type.GetFields on dynamic types but get the fields from the
185 corresponding TypeContainer.
186 (MyStructInfo.GetStructInfo): Added check for enum types.
188 * typemanager.cs (MemberList.IsSynchronized): Implemented.
189 (MemberList.SyncRoot): Implemented.
190 (TypeManager.FilterWithClosure): No need to check permissions if
191 closure_start_type == closure_invocation_type, don't crash if
192 closure_invocation_type is null.
194 2002-08-13 Martin Baulig <martin@gnome.org>
196 Rewrote TypeContainer.FindMembers to use a member cache. This
197 gives us a speed increase of about 35% for the self-hosting MCS
198 build and of about 15-20% for the class libs (both on GNU/Linux).
200 * report.cs (Timer): New class to get enhanced profiling. This
201 whole class is "TIMER" conditional since it remarkably slows down
204 * class.cs (MemberList): New class. This is an IList wrapper
205 which we're now using instead of passing MemberInfo[]'s around to
206 avoid copying this array unnecessarily.
207 (IMemberFinder.FindMember): Return a MemberList, not a MemberInfo [].
208 (ICachingMemberFinder, IMemberContainer): New interface.
209 (TypeManager.FilterWithClosure): If `criteria' is null, the name
210 has already been checked, otherwise use it for the name comparision.
211 (TypeManager.FindMembers): Renamed to RealMemberFinder and
212 provided wrapper which tries to use ICachingMemberFinder.FindMembers
213 if possible. Returns a MemberList, not a MemberInfo [].
214 (TypeHandle): New class, implements IMemberContainer. We create
215 one instance of this class per type, it contains a MemberCache
216 which is used to do the member lookups.
217 (MemberCache): New class. Each instance of this class contains
218 all members of a type and a name-based hash table.
219 (MemberCache.FindMembers): This is our new member lookup
220 function. First, it looks up all members of the requested name in
221 the hash table. Then, it walks this list and sorts out all
222 applicable members and returns them.
224 2002-08-13 Martin Baulig <martin@gnome.org>
226 In addition to a nice code cleanup, this gives us a performance
227 increase of about 1.4% on GNU/Linux - not much, but it's already
228 half a second for the self-hosting MCS compilation.
230 * typemanager.cs (IMemberFinder): New interface. It is used by
231 TypeManager.FindMembers to call FindMembers on a TypeContainer,
232 Enum, Delegate or Interface.
233 (TypeManager.finder_to_member_finder): New PtrHashtable.
234 (TypeManager.finder_to_container): Removed.
235 (TypeManager.finder_to_delegate): Removed.
236 (TypeManager.finder_to_interface): Removed.
237 (TypeManager.finder_to_enum): Removed.
239 * interface.cs (Interface): Implement IMemberFinder.
241 * delegate.cs (Delegate): Implement IMemberFinder.
243 * enum.cs (Enum): Implement IMemberFinder.
245 * class.cs (TypeContainer): Implement IMemberFinder.
247 2002-08-12 Martin Baulig <martin@gnome.org>
249 * ecore.cs (TypeExpr.DoResolveType): Mark this as virtual.
251 2002-08-12 Martin Baulig <martin@gnome.org>
253 * ecore.cs (ITypeExpression): New interface for expressions which
255 (TypeExpression): Renamed to TypeLookupExpression.
256 (Expression.DoResolve): If we're doing a types-only lookup, the
257 expression must implement the ITypeExpression interface and we
258 call DoResolveType() on it.
259 (SimpleName): Implement the new ITypeExpression interface.
260 (SimpleName.SimpleNameResolve): Removed the ec.OnlyLookupTypes
261 hack, the situation that we're only looking up types can't happen
262 anymore when this method is called. Moved the type lookup code to
263 DoResolveType() and call it.
264 (SimpleName.DoResolveType): This ITypeExpression interface method
265 is now doing the types-only lookup.
266 (TypeExpr, TypeLookupExpression): Implement ITypeExpression.
267 (ResolveFlags): Added MaskExprClass.
269 * expression.cs (MemberAccess): Implement the ITypeExpression
271 (MemberAccess.DoResolve): Added support for a types-only lookup
272 when we're called via ITypeExpression.DoResolveType().
273 (ComposedCast): Implement the ITypeExpression interface.
275 * codegen.cs (EmitContext.OnlyLookupTypes): Removed. Call
276 Expression.Resolve() with ResolveFlags.Type instead.
278 2002-08-12 Martin Baulig <martin@gnome.org>
280 * attribute.cs (Attribute.Resolve): Call System.Enum.ToObject() on
281 enum constants so that we encode the value with the enum type and
282 not its underlying type.
284 2002-08-12 Martin Baulig <martin@gnome.org>
286 * interface.cs (Interface.Define): Apply attributes.
288 * attribute.cs (Attribute.ApplyAttributes): Added support for
289 interface attributes.
291 2002-08-11 Martin Baulig <martin@gnome.org>
293 * statement.cs (Block.Emit): Only check the "this" variable if we
294 do not always throw an exception.
296 * ecore.cs (PropertyExpr.DoResolveLValue): Implemented, check
297 whether the property has a set accessor.
299 2002-08-11 Martin Baulig <martin@gnome.org>
301 Added control flow analysis support for structs.
303 * ecore.cs (ResolveFlags): Added `DisableFlowAnalysis' to resolve
304 with control flow analysis turned off.
305 (IVariable): New interface.
306 (SimpleName.SimpleNameResolve): If MemberAccess.ResolveMemberAccess
307 returns an IMemberExpr, call DoResolve/DoResolveLValue on it.
308 (FieldExpr.DoResolve): Resolve the instance expression with flow
309 analysis turned off and do the definite assignment check after the
310 resolving when we know what the expression will resolve to.
312 * expression.cs (LocalVariableReference, ParameterReference):
313 Implement the new IVariable interface, only call the flow analysis
314 code if ec.DoFlowAnalysis is true.
315 (This): Added constructor which takes a Block argument. Implement
316 the new IVariable interface.
317 (MemberAccess.DoResolve, MemberAccess.DoResolveLValue): Call
318 DoResolve/DoResolveLValue on the result of ResolveMemberLookup().
319 This does the definite assignment checks for struct members.
321 * class.cs (Constructor.Emit): If this is a non-static `struct'
322 constructor which doesn't have any initializer, call
323 Block.AddThisVariable() to tell the flow analysis code that all
324 struct elements must be initialized before control returns from
327 * statement.cs (MyStructInfo): New public class.
328 (UsageVector.this [VariableInfo vi]): Added `int field_idx'
329 argument to this indexer. If non-zero, check an individual struct
330 member, not the whole struct.
331 (FlowBranching.CheckOutParameters): Check struct members.
332 (FlowBranching.IsVariableAssigned, SetVariableAssigned): Added
333 overloaded versions of these methods which take an additional
334 `int field_idx' argument to check struct members.
335 (FlowBranching.IsParameterAssigned, SetParameterAssigned): Added
336 overloaded versions of these methods which take an additional
337 `string field_name' argument to check struct member.s
338 (VariableInfo): Implement the IVariable interface.
339 (VariableInfo.StructInfo): New public property. Returns the
340 MyStructInfo instance of the variable if it's a struct or null.
341 (Block.AddThisVariable): New public method. This is called from
342 Constructor.Emit() for non-static `struct' constructor which do
343 not have any initializer. It creates a special variable for the
344 "this" instance variable which will be checked by the flow
345 analysis code to ensure that all of the struct's fields are
346 initialized before control returns from the constructor.
347 (UsageVector): Added support for struct members. If a
348 variable/parameter is a struct with N members, we reserve a slot
349 in the usage vector for each member. A struct is considered fully
350 initialized if either the struct itself (slot 0) or all its
351 members are initialized.
353 2002-08-08 Martin Baulig <martin@gnome.org>
355 * driver.cs (Driver.MainDriver): Only report an error CS5001
356 if there were no compilation errors.
358 * codegen.cs (EmitContext.EmitContext): Use the DeclSpace's
359 `UnsafeContext' property to determine whether the parent is in
360 unsafe context rather than checking the parent's ModFlags:
361 classes nested in an unsafe class are unsafe as well.
363 2002-08-08 Martin Baulig <martin@gnome.org>
365 * statement.cs (UsageVector.MergeChildren): Distinguish between
366 `Breaks' and `Returns' everywhere, don't set `Breaks' anymore if
367 we return. Added test17() and test18() to test-154.cs.
369 2002-08-08 Martin Baulig <martin@gnome.org>
371 * typemanager.cs (TypeManager.FilterWithClosure): If we have
372 Family access, make sure the invoking type isn't a subclass of the
373 queried type (that'd be a CS1540).
375 * ecore.cs (Expression.MemberLookup): Added overloaded version of
376 this method which takes an additional `Type invocation_type'.
378 * expression.cs (BaseAccess.DoResolve): Use the base type as
379 invocation and query type.
380 (MemberAccess.DoResolve): If the lookup failed and we're about to
381 report a CS0122, try a lookup with the ec.ContainerType - if this
382 succeeds, we must report a CS1540.
384 2002-08-08 Martin Baulig <martin@gnome.org>
386 * ecore.cs (IMemberExpr): Added `bool IsInstance' property.
387 (MethodGroupExpr): Implement the IMemberExpr interface.
389 * expression (MemberAccess.ResolveMemberAccess): No need to have
390 any special code for MethodGroupExprs anymore, they're now
393 2002-08-08 Martin Baulig <martin@gnome.org>
395 * typemanager.cs (TypeManager.FilterWithClosure): Check Assembly,
396 Family, FamANDAssem and FamORAssem permissions.
397 (TypeManager.IsSubclassOrNestedChildOf): New public method.
399 2002-08-08 Martin Baulig <martin@gnome.org>
401 * statement.cs (FlowBranchingType): Added LOOP_BLOCK.
402 (UsageVector.MergeChildren): `break' breaks unless we're in a switch
405 Thu Aug 8 10:28:07 CEST 2002 Paolo Molaro <lupus@ximian.com>
407 * driver.cs: implemented /resource option to embed managed resources.
409 2002-08-07 Martin Baulig <martin@gnome.org>
411 * class.cs (FieldBase.Initializer): Renamed to `init' and made private.
412 (FieldBase.HasFieldInitializer): New public property.
413 (FieldBase.GetInitializerExpression): New public method. Resolves and
414 returns the field initializer and makes sure it is only resolved once.
415 (TypeContainer.EmitFieldInitializers): Call
416 FieldBase.GetInitializerExpression to get the initializer, this ensures
417 that it isn't resolved multiple times.
419 * codegen.cs (EmitContext): Added `bool IsFieldInitialier'. This tells
420 the resolving process (SimpleName/MemberLookup) that we're currently
421 emitting a field initializer (which must not access any instance members,
422 this is an error CS0236).
424 * ecore.cs (SimpleName.Error_ObjectRefRequired): Added EmitContext
425 argument, if the `IsFieldInitializer' flag is set, we must report and
426 error CS0236 and not an error CS0120.
428 2002-08-07 Martin Baulig <martin@gnome.org>
430 * ecore.cs (IMemberExpr): New public interface.
431 (FieldExpr, PropertyExpr, EventExpr): Implement IMemberExpr.
432 (SimpleName.SimpleNameResolve): Call MemberAccess.ResolveMemberAccess
433 if the expression is an IMemberExpr.
435 * expression.cs (MemberAccess.ResolveMemberAccess): Allow `left'
436 to be null, implicitly default to `this' if we're non-static in
437 this case. Simplified the code a lot by using the new IMemberExpr
438 interface. Also fixed bug #28176 here.
440 2002-08-06 Martin Baulig <martin@gnome.org>
442 * cs-parser.jay (SimpleLookup): Removed. We need to create
443 ParameterReferences during semantic analysis so that we can do a
444 type-only search when resolving Cast, TypeOf and SizeOf.
445 (block): Pass the `current_local_parameters' to the Block's
448 * class.cs (ConstructorInitializer): Added `Parameters parameters'
449 argument to the constructor.
450 (ConstructorInitializer.Resolve): Create a temporary implicit
451 block with the parameters.
453 * ecore.cs (SimpleName.SimpleNameResolve): Resolve parameter
454 references here if we aren't doing a type-only search.
456 * statement.cs (Block): Added constructor which takes a
457 `Parameters parameters' argument.
458 (Block.Parameters): New public property.
460 * support.cs (InternalParameters.Parameters): Renamed `parameters'
461 to `Parameters' and made it public readonly.
463 2002-08-06 Martin Baulig <martin@gnome.org>
465 * ecore.cs (Expression.Warning): Made this public as well.
467 * report.cs (Report.Debug): Print the contents of collections.
469 2002-08-06 Martin Baulig <martin@gnome.org>
471 * ecore.cs (Expression.ResolveFlags): New [Flags] enum. This is
472 used to tell Resolve() which kinds of expressions it may return.
473 (Expression.Resolve): Added overloaded version of this method which
474 takes a `ResolveFlags flags' argument. This can be used to tell
475 Resolve() which kinds of expressions it may return. Reports a
477 (Expression.ResolveWithSimpleName): Removed, use Resolve() with
478 ResolveFlags.SimpleName.
479 (Expression.Error118): Added overloaded version of this method which
480 takes a `ResolveFlags flags' argument. It uses the flags to determine
481 which kinds of expressions are allowed.
483 * expression.cs (Argument.ResolveMethodGroup): New public method.
484 Resolves an argument, but allows a MethodGroup to be returned.
485 This is used when invoking a delegate.
487 * TODO: Updated a bit.
489 2002-08-06 Gonzalo Paniagua Javier <gonzalo@ximian.com>
491 Fixed compilation with csc.
493 * ecore.cs: Expression.Error made public. Is this correct? Should
494 Warning be made public too?
496 * expression.cs: use ea.Location instead of ea.loc.
497 [FIXME: Filed as bug #28607: MCS must report these errors.]
499 2002-08-06 Martin Baulig <martin@gnome.org>
501 * ecore.cs (Expression.loc): Moved the location here instead of
502 duplicating it in all derived classes.
503 (Expression.Location): New public property.
504 (Expression.Error, Expression.Warning): Made them non-static and
505 removed the location argument.
506 (Expression.Warning): Added overloaded version which takes an
507 `int level' argument.
508 (Expression.Error118): Make this non-static and removed the
509 expression and location arguments.
510 (TypeExpr): Added location argument to the constructor.
512 * expression.cs (StaticCallExpr): Added location argument to
514 (Indirection, PointerArithmetic): Likewise.
515 (CheckedExpr, UnCheckedExpr): Likewise.
516 (ArrayAccess, IndexerAccess, UserCast, ArrayPtr): Likewise.
517 (StringPtr): Likewise.
520 2002-08-05 Martin Baulig <martin@gnome.org>
522 * expression.cs (BaseAccess.DoResolve): Actually report errors.
524 * assign.cs (Assign.DoResolve): Check whether the source
525 expression is a value or variable.
527 * statement.cs (Try.Resolve): Set ec.InTry/InCatch/InFinally
528 while resolving the corresponding blocks.
530 * interface.cs (Interface.GetInterfaceTypeByName): Actually report
531 an error, don't silently return null.
533 * statement.cs (Block.AddVariable): Do the error reporting here
534 and distinguish between CS0128 and CS0136.
535 (Block.DoResolve): Report all unused labels (warning CS0164).
536 (LabeledStatement): Pass the location to the constructor.
537 (LabeledStatement.HasBeenReferenced): New property.
538 (LabeledStatement.Resolve): Set it to true here.
540 * statement.cs (Return.Emit): Return success even after reporting
541 a type mismatch error (CS0126 or CS0127), this is what csc does and
542 it avoids confusing the users with any consecutive errors.
544 2002-08-05 Martin Baulig <martin@gnome.org>
546 * enum.cs (Enum.LookupEnumValue): Catch circular definitions.
548 * const.cs (Const.LookupConstantValue): Catch circular definitions.
550 * expression.cs (MemberAccess.DoResolve): Silently return if an
551 error has already been reported.
553 * ecore.cs (Expression.MemberLookupFinal): Silently return if an
554 error has already been reported.
556 2002-08-05 Martin Baulig <martin@gnome.org>
558 * statement.cs (UsageVector): Only initialize the `parameters'
559 vector if we actually have any "out" parameters.
561 2002-08-05 Martin Baulig <martin@gnome.org>
563 * expression.cs (Binary.ResolveOperator): When combining delegates,
564 they must have the same type.
566 2002-08-05 Martin Baulig <martin@gnome.org>
568 * typemanager.cs (TypeManager.GetArgumentTypes): Don't call
569 PropertyInfo.GetIndexParameters() on dynamic types, this doesn't
570 work with the ms runtime and we also don't need it: if we're a
571 PropertyBuilder and not in the `indexer_arguments' hash, then we
572 are a property and not an indexer.
574 * class.cs (TypeContainer.AsAccessible): Use Type.IsArray,
575 Type.IsPointer and Type.IsByRef instead of Type.HasElementType
576 since the latter one doesn't work with the ms runtime.
578 2002-08-03 Martin Baulig <martin@gnome.org>

760 * statement.cs (Fixed): Moved all code that does variable lookups
761 and resolvings from Emit to Resolve.
763 * statement.cs (For): Moved all code that does variable lookups
764 and resolvings from Emit to Resolve.
766 * statement.cs (Using): Moved all code that does variable lookups
767 and resolvings from Emit to Resolve.
769 2002-07-29 Martin Baulig <martin@gnome.org>
771 * attribute.cs (Attribute.Resolve): Explicitly catch a

840 2002-07-27 Martin Baulig <martin@gnome.org>
842 * expression.cs (Invocation.EmitArguments): When calling a varargs
843 function with only its fixed arguments, we need to pass an empty
846 2002-07-27 Martin Baulig <martin@gnome.org>
848 Mono 0.13 has been released.
850 2002-07-25 Miguel de Icaza <miguel@ximian.com>
852 * driver.cs: Rename --resource to --linkres, because that is what
853 we do currently, we dont support --resource yet.
855 * cs-tokenizer.cs: Fix test for reporting endif mismatches.
857 2002-07-25 Martin Baulig <martin@gnome.org>
859 * class.cs (MethodData): New public class. This is a `method builder'
860 class for a method or one accessor of a Property/Indexer/Event.
861 (MethodData.GetMethodFlags): Moved here from MemberBase.
862 (MethodData.ApplyAttributes): Likewise.
863 (MethodData.ApplyObsoleteAttribute): Likewise.
864 (MethodData.ApplyConditionalAttribute): Likewise.
865 (MethodData.ApplyDllImportAttribute): Likewise.
866 (MethodData.CheckAbstractAndExternal): Likewise.
867 (MethodData.Define): Formerly knows as MemberBase.DefineMethod().
868 (MethodData.Emit): Formerly known as Method.Emit().
869 (MemberBase): Moved everything which was specific to a single
870 accessor/method to MethodData.
871 (Method): Create a new MethodData and call Define() and Emit() on it.
872 (Property, Indexer, Event): Create a new MethodData objects for each
873 accessor and call Define() and Emit() on them.
875 2002-07-25 Martin Baulig <martin@gnome.org>
877 Made MethodCore derive from MemberBase to reuse the code from there.
878 MemberBase now also checks for attributes.
880 * class.cs (MethodCore): Derive from MemberBase, not MemberCore.
881 (MemberBase.GetMethodFlags): Moved here from class Method and marked
883 (MemberBase.DefineAccessor): Renamed to DefineMethod(), added
884 `CallingConventions cc' and `Attributes opt_attrs' arguments.

886 attributes to a method or accessor.
887 (MemberBase.ApplyObsoleteAttribute): New protected virtual method.
888 (MemberBase.ApplyConditionalAttribute): Likewise.
889 (MemberBase.ApplyDllImportAttribute): Likewise.
890 (MemberBase.CheckAbstractAndExternal): Likewise.
891 (MethodCore.ParameterTypes): This is now a property instead of a
892 method, it's initialized from DoDefineParameters().
893 (MethodCore.ParameterInfo): Removed the set accessor.
894 (MethodCore.DoDefineParameters): New protected virtual method to
895 initialize ParameterTypes and ParameterInfo.
896 (Method.GetReturnType): We can now simply return the MemberType.
897 (Method.GetMethodFlags): Override the MemberBase version and add
898 the conditional flags.
899 (Method.CheckBase): Moved some code from Define() here, call
900 DoDefineParameters() here.
901 (Method.Define): Use DoDefine() and DefineMethod() from MemberBase
902 here to avoid some larger code duplication.
903 (Property.Emit, Indexer.Emit): Call CheckAbstractAndExternal() to
904 ensure that abstract and external accessors don't declare a body.
906 * attribute.cs (Attribute.GetValidPieces): Make this actually work:
907 `System.Attribute.GetCustomAttributes (attr.Type)' does a recursive
908 lookup in the attribute's parent classes, so we need to abort as soon
909 as we found the first match.
910 (Attribute.Obsolete_GetObsoleteMessage): Return the empty string if
911 the attribute has no arguments.
913 * typemanager.cs (TypeManager.AddMethod): Now takes a MemberBase instead
916 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
918 * cs-parser.jay: reverted previous patch.
920 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
922 * cs-parser.jay: fixed bug #22119.
924 2002-07-24 Gonzalo Paniagua Javier <gonzalo@ximian.com>
926 * attribute.cs: fixed compilation. The error was:
927 "attribute.cs(571,17): error CS0177: The out parameter 'is_error' must
928 be assigned to before control leaves the current method."
929 [FIXME: Filed as bug #28186: MCS must report this error.]
931 2002-07-25 Martin Baulig <martin@gnome.org>
933 * attribute.cs (Attribute.Conditional_GetConditionName): New static
934 method to pull the condition name ouf of a Conditional attribute.
935 (Attribute.Obsolete_GetObsoleteMessage): New static method to pull
936 the obsolete message and error flag out of an Obsolete attribute.
938 * class.cs (Method.GetMethodFlags): New public method to get the
939 TypeManager.MethodFlags for this method.
940 (Method.ApplyConditionalAttribute, Method.ApplyObsoleteAttribute): New
942 (Method.Define): Get and apply the Obsolete and Conditional attributes;
943 if we're overriding a virtual function, set the new private variable
944 `parent_method'; call the new TypeManager.AddMethod().
946 * typemanager.cs (TypeManager.AddMethod): New static method. Stores
947 the MethodBuilder and the Method in a PtrHashtable.
948 (TypeManager.builder_to_method): Added for this purpose.
949 (TypeManager.MethodFlags): Added IsObsoleteError.
950 (TypeManager.GetMethodFlags): Added `Location loc' argument. Lookup
951 Obsolete and Conditional arguments in MethodBuilders. If we discover
952 an Obsolete attribute, emit an appropriate warning 618 / error 619 with
953 the message from the attribute.
955 2002-07-24 Martin Baulig <martin@gnome.org>
957 * cs-tokenizer.cs: Eat up trailing whitespaces and one-line comments in
958 preprocessor directives, ensure that the argument to #define/#undef is
959 exactly one identifier and that it's actually an identifier.
961 Some weeks ago I did a `#define DEBUG 1' myself and wondered why this
964 2002-07-24 Martin Baulig <martin@gnome.org>
966 * statement.cs (Foreach.ForeachHelperMethods): Added `Type element_type',
967 initialize it to TypeManager.object_type in the constructor.
968 (Foreach.GetEnumeratorFilter): Set `hm.element_type' to the return type
969 of the `hm.get_current' method if we're using the collection pattern.
970 (Foreach.EmitCollectionForeach): Use `hm.element_type' as the source type
971 for the explicit conversion to make it work when we're using the collection
972 pattern and the `Current' property has a different return type than `object'.
975 2002-07-24 Martin Baulig <martin@gnome.org>
977 * delegate.cs (Delegate.VerifyMethod): Simply return null if the method
978 does not match, but don't report any errors. This method is called in
979 order for all methods in a MethodGroupExpr until a matching method is
980 found, so we don't want to bail out if the first method doesn't match.
981 (NewDelegate.DoResolve): If none of the methods in the MethodGroupExpr
982 matches, report the 123. Fixes #28070.
984 2002-07-24 Martin Baulig <martin@gnome.org>
986 * expression.cs (ArrayAccess.EmitStoreOpcode): Moved the
987 TypeManager.TypeToCoreType() to the top of the method so the
988 following equality checks will work. Fixes #28107.
990 2002-07-24 Martin Baulig <martin@gnome.org>
992 * cfold.cs (ConstantFold.DoConstantNumericPromotions): "If either
993 operand is of type uint, and the other operand is of type sbyte,
994 short or int, the operands are converted to type long." -
995 Actually do what this comment already told us. Fixes bug #28106,
998 2002-07-24 Martin Baulig <martin@gnome.org>
1000 * class.cs (MethodBase): New abstract class. This is now a base
1001 class for Property, Indexer and Event to avoid some code duplication
1002 in their Define() and DefineMethods() methods.
1003 (MethodBase.DoDefine, MethodBase.DefineAccessor): Provide virtual
1004 generic methods for Define() and DefineMethods().
1005 (FieldBase): Derive from MemberBase, not MemberCore.
1006 (Property): Derive from MemberBase, not MemberCore.
1007 (Property.DefineMethod): Moved all the code from this method to the
1008 new MethodBase.DefineAccessor(), just call it with appropriate
1010 (Property.Define): Call the new Property.DoDefine(), this does some
1011 sanity checks and we don't need to duplicate the code everywhere.
1012 (Event): Derive from MemberBase, not MemberCore.
1013 (Event.Define): Use the new MethodBase.DefineAccessor() to define the
1014 accessors, this will also make them work with interface events.
1015 (Indexer): Derive from MemberBase, not MemberCore.
1016 (Indexer.DefineMethod): Removed, call MethodBase.DefineAccessor() insstead.
1017 (Indexer.Define): Use the new MethodBase functions.
1019 * interface.cs (InterfaceEvent.InterfaceEvent): Added `Location loc'
1020 argument to the constructor.
1021 (Interface.FindMembers): Added support for interface events.
1022 (Interface.PopluateEvent): Implemented.
1024 Added test-149.cs for this. This also fixes bugs #26067 and #24256.
1026 2002-07-22 Miguel de Icaza <miguel@ximian.com>
1028 * class.cs (TypeContainer.AddMethod): Adding methods do not use IsValid,
1029 but this is required to check for a method name being the same as
1030 the containing class.
1034 2002-07-22 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1036 * interface.cs: initialize variable.
1038 2002-07-23 Martin Baulig <martin@gnome.org>
1040 Implemented the IndexerName attribute in interfaces.
1042 * class.cs (TypeContainer.DefineIndexers): Don't set the indexer
1043 name if this is an explicit interface implementation.
1044 (Indexer.InterfaceIndexerName): New public variable. If we're
1045 implementing an interface indexer, this is the IndexerName in that
1046 interface. Otherwise, it's the IndexerName.
1047 (Indexer.DefineMethod): If we're implementing interface indexer,
1048 set InterfaceIndexerName. Use the new Pending.IsInterfaceIndexer
1049 and Pending.ImplementIndexer methods.
1050 (Indexer.Define): Also define the PropertyBuilder if we're
1051 implementing an interface indexer and this is neither an explicit
1052 interface implementation nor do the IndexerName match the one in
1055 * pending.cs (TypeAndMethods): Added `MethodInfo [] need_proxy'.
1056 If a method is defined here, then we always need to create a proxy
1057 for it. This is used when implementing interface indexers.
1058 (Pending.IsInterfaceIndexer): New public method.
1059 (Pending.ImplementIndexer): New public method.
1060 (Pending.InterfaceMethod): Added `MethodInfo need_proxy' argument.
1061 This is used when implementing interface indexers to define a proxy
1063 (Pending.VerifyPendingMethods): Look in the `need_proxy' array and
1064 define a proxy if necessary.
1066 * interface.cs (Interface.IndexerName): New public variable.
1067 (Interface.PopulateIndexer): Set the IndexerName.
1068 (Interface.DefineIndexers): New private method. Populate all the
1069 indexers and make sure their IndexerNames match.
1071 * typemanager.cs (IndexerPropertyName): Added support for interface
1074 2002-07-22 Martin Baulig <martin@gnome.org>
1076 * codegen.cs (EmitContext.HasReturnLabel): New public variable.
1077 (EmitContext.EmitTopBlock): Always mark the ReturnLabel and emit a
1078 ret if HasReturnLabel.
1079 (EmitContext.TryCatchLevel, LoopBeginTryCatchLevel): New public
1082 * statement.cs (Do.Emit, While.Emit, For.Emit, Foreach.Emit): Save
1083 and set the ec.LoopBeginTryCatchLevel.
1084 (Try.Emit): Increment the ec.TryCatchLevel while emitting the block.
1085 (Continue.Emit): If the ec.LoopBeginTryCatchLevel is smaller than
1086 the current ec.TryCatchLevel, the branch goes out of an exception
1087 block. In this case, we need to use Leave and not Br.
1089 2002-07-22 Martin Baulig <martin@gnome.org>
1091 * statement.cs (Try.Emit): Emit an explicit ret after the end of the
1092 block unless the block does not always return or it is contained in
1093 another try { ... } catch { ... } block. Fixes bug #26506.
1094 Added verify-1.cs to the test suite.
1096 2002-07-22 Martin Baulig <martin@gnome.org>
1098 * statement.cs (Switch.TableSwitchEmit): If we don't have a default,
1099 then we do not always return. Fixes bug #24985.
1101 2002-07-22 Martin Baulig <martin@gnome.org>
1103 * expression.cs (Invocation.OverloadedResolve): Do the BetterFunction()
1104 lookup on a per-class level; ie. walk up the class hierarchy until we
1105 found at least one applicable method, then choose the best among them.
1106 Fixes bug #24463 and test-29.cs.
1108 2002-07-22 Martin Baulig <martin@gnome.org>
1110 * typemanager.cs (TypeManager.ArrayContainsMethod): Don't check the
1111 return types of the methods. The return type is not part of the
1112 signature and we must not check it to make the `new' modifier work.
1113 Fixes bug #27999, also added test-147.cs.
1114 (TypeManager.TypeToCoreType): Added TypeManager.type_type.
1116 * expression.cs (Invocation.DoResolve): Call TypeManager.TypeToCoreType()
1117 on the method's return type.
1119 2002-07-21 Martin Baulig <martin@gnome.org>
1121 * assign.cs: Make this work if the rightmost source is a constant and
1122 we need to do an implicit type conversion. Also adding a few more tests
1123 to test-38.cs which should have caught this.
1125 * makefile.gnu: Disable debugging, there's already the mcs-mono2.exe
1126 target in the makefile for this. The makefile.gnu is primarily intended
1127 for end-users who don't want to debug the compiler.
1129 2002-07-21 Martin Baulig <martin@gnome.org>
1131 * assign.cs: Improved the Assign class so it can now handle embedded
1132 assignments (X = Y = Z = something). As a side-effect this'll now also
1133 consume less local variables. test-38.cs now passes with MCS, added
1134 a few new test cases to that test.
1136 2002-07-20 Martin Baulig <martin@gnome.org>
1138 * expression.cs (Binary.EmitBranchable): Emit correct unsigned branch
1139 instructions. Fixes bug #27977, also added test-146.cs.
1141 2002-07-19 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1143 * cs-tokenizer.cs: fixed getHex ().
1145 2002-07-19 Martin Baulig <martin@gnome.org>
1147 * expression.cs (Invocation.EmitParams): Use TypeManager.LookupType(),
1148 not Type.GetType() to lookup the array type. This is needed when
1149 we're constructing an array of a user-defined type.
1150 (ArrayAccess.EmitDynamicInitializers): Only emit the Ldelema for
1151 single-dimensional arrays, but also for single-dimensial arrays of
1154 2002-07-19 Martin Baulig <martin@gnome.org>
1156 * expression.cs (New.DoEmit): Create a new LocalTemporary each time
1157 this function is called, it's not allowed to share LocalBuilders
1160 2002-07-19 Martin Baulig <martin@gnome.org>
1162 * expression.cs (Argument.Resolve): Report an error 118 when trying
1163 to pass a type as argument.
1165 2002-07-18 Martin Baulig <martin@gnome.org>
1167 * ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
1168 Conv_R_Un for the signed `long' type.
1170 2002-07-15 Miguel de Icaza <miguel@ximian.com>
1172 * expression.cs (MemberAccess.DoResolve): Do not reuse the field
1173 `expr' for the temporary result, as that will fail if we do
1174 multiple resolves on the same expression.
1176 2002-07-05 Miguel de Icaza <miguel@ximian.com>
1178 * ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
1179 ec.TypeContainer for looking up aliases.
1181 * class.cs (TypeContainer): Remove LookupAlias from here.
1183 * decl.cs (DeclSpace); Move here.
1185 2002-07-01 Miguel de Icaza <miguel@ximian.com>
1187 * class.cs (FindMembers): Only call filter if the constructor
1188 bulider is not null.
1190 Also handle delegates in `NestedTypes' now. Now we will perform
1191 type lookups using the standard resolution process. This also
1194 * decl.cs (DeclSpace.ResolveType): New type resolution routine.
1195 This uses Expressions (the limited kind that can be parsed by the
1196 tree) instead of strings.
1198 * expression.cs (ComposedCast.ToString): Implement, used to flag
1199 errors since now we have to render expressions.
1201 (ArrayCreation): Kill FormElementType. Use ComposedCasts in
1204 * ecore.cs (SimpleName.ToString): ditto.
1206 * cs-parser.jay: Instead of using strings to assemble types, use
1207 Expressions to assemble the type (using SimpleName, ComposedCast,
1208 MemberAccess). This should fix the type lookups in declarations,
1209 because we were using a different code path for this.
1211 * statement.cs (Block.Resolve): Continue processing statements
1212 even when there is an error.
1214 2002-07-17 Miguel de Icaza <miguel@ximian.com>
1216 * class.cs (Event.Define): Also remove the `remove' method from
1217 the list of pending items.
1219 * expression.cs (ParameterReference): Use ldarg.N (0..3) to
1220 generate more compact code.
1222 2002-07-17 Martin Baulig <martin@gnome.org>
1224 * const.cs (Const.LookupConstantValue): Add support for constant
1225 `unchecked' and `checked' expressions.
1226 Also adding test case test-140.cs for this.
1228 2002-07-17 Martin Baulig <martin@gnome.org>
1230 * statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
1231 check whether mi.ReturnType implements the IEnumerator interface; the
1232 `==' and the IsAssignableFrom() will fail in this situation.
1234 2002-07-16 Ravi Pratap <ravi@ximian.com>
1236 * ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix
1239 2002-07-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1241 * expression.cs: fixed bug #27811.
1243 2002-07-14 Miguel de Icaza <miguel@ximian.com>
1245 * expression.cs (ParameterReference.AddressOf): Patch from Paolo
1246 Molaro: when we are a ref, the value already contains a pointer
1247 value, do not take the address of it.
1249 2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1250 * removed mb-parser.jay and mb-tokenizer.cs
1252 Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
1254 * expression.cs: check against the building corlib void type.
1256 Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
1258 * ecore.cs: fix for valuetype static readonly fields: when
1259 initializing them, we need their address, not the address of a copy.
1261 Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
1263 * typemanager.cs: register also enum_type in corlib.
1265 Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
1267 * class.cs: allow calling this (but not base) initializers in structs.
1269 Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
1271 * ecore.cs: make sure we compare against the building base types
1274 Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
1276 * typemanager.cs: fix TypeToCoreType() to handle void and object
1277 (corlib gets no more typerefs after this change).
1279 2002-07-12 Miguel de Icaza <miguel@ximian.com>
1281 * expression.cs (ArrayCreation.EmitArrayArguments): use
1282 Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
1284 (ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
1285 Conv_Ovf_I_Un for the array arguments. Even if C# allows longs as
1286 array indexes, the runtime actually forbids them.
1288 * ecore.cs (ExpressionToArrayArgument): Move the conversion code
1289 for array arguments here.
1291 * expression.cs (EmitLoadOpcode): System.Char is a U2, use that
1292 instead of the default for ValueTypes.
1294 (New.DoEmit): Use IsValueType instead of
1295 IsSubclassOf (value_type)
1296 (New.DoResolve): ditto.
1297 (Invocation.EmitCall): ditto.
1299 * assign.cs (Assign): ditto.
1301 * statement.cs (Unsafe): Ok, so I got the semantics wrong.
1302 Statements *are* currently doing part of their resolution during
1305 Expressions do always resolve during resolve, but statements are
1306 only required to propagate resolution to their children.
1308 2002-07-11 Miguel de Icaza <miguel@ximian.com>
1310 * driver.cs (CSCParseOption): Finish the /r: and /lib: support.
1312 (LoadAssembly): Do not add the dll if it is already specified
1314 (MainDriver): Add the System directory to the link path at the end,
1315 after all the other -L arguments.
1317 * expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
1318 wrong opcode for loading bytes and bools (ldelem.i1 instead of
1319 ldelem.u1) and using the opposite for sbytes.
1321 This fixes Digger, and we can finally run it.
1323 * driver.cs (UnixParseOption): Move the option parsing here.
1324 (CSCParseOption): Implement CSC-like parsing of options.
1326 We now support both modes of operation, the old Unix way, and the
1327 new CSC-like way. This should help those who wanted to make cross
1330 The only thing broken is that /r:, /reference: and /lib: are not
1331 implemented, because I want to make those have the same semantics
1332 as the CSC compiler has, and kill once and for all the confussion
1333 around this. Will be doing this tomorrow.
1335 * statement.cs (Unsafe.Resolve): The state is checked during
1336 resolve, not emit, so we have to set the flags for IsUnsfe here.
1338 2002-07-10 Miguel de Icaza <miguel@ximian.com>
1340 * expression.cs (MemberAccess.ResolveMemberAccess): Since we can
1341 not catch the Error_ObjectRefRequired in SimpleName (as it is
1342 possible to have a class/instance variable name that later gets
1343 deambiguated), we have to check this here.
1345 2002-07-10 Ravi Pratap <ravi@ximian.com>
1347 * class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
1348 make static and put into Expression.
1350 (Event.Define): Register the private field of the event with the
1351 TypeManager so that GetFieldFromEvent can get at it.
1353 (TypeManager.RegisterPrivateFieldOfEvent): Implement to
1354 keep track of the private field associated with an event which
1357 (TypeManager.GetPrivateFieldOfEvent): Implement to get at the
1360 * ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
1362 2002-07-10 Miguel de Icaza <miguel@ximian.com>
1364 * expression.cs (Binary.EmitBranchable): this routine emits the
1365 Binary expression in a branchable context. This basically means:
1366 we need to branch somewhere, not just get the value on the stack.
1368 This works together with Statement.EmitBoolExpression.
1370 * statement.cs (Statement.EmitBoolExpression): Use
1373 2002-07-09 Miguel de Icaza <miguel@ximian.com>
1375 * statement.cs (For): Reduce the number of jumps in loops.
1377 (For): Implement loop inversion for the For statement.
1379 (Break): We can be breaking out of a Try/Catch controlled section
1380 (foreach might have an implicit try/catch clause), so we need to
1381 use Leave instead of Br.
1383 * ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
1384 now). If the instace expression supports IMemoryLocation, we use
1385 the AddressOf method from the IMemoryLocation to extract the
1386 address instead of emitting the instance.
1388 This showed up with `This', as we were emitting the instance
1389 always (Emit) instead of the Address of This. Particularly
1390 interesting when This is a value type, as we dont want the Emit
1391 effect (which was to load the object).
1393 2002-07-08 Miguel de Icaza <miguel@ximian.com>
1395 * attribute.cs: Pass the entry point to the DefinePInvokeMethod
1397 * statement.cs (Checked): Set the CheckedState during the resolve
1398 process too, as the ConvCast operations track the checked state on
1399 the resolve process, and not emit.
1401 * cs-parser.jay (namespace_member_declaration): Flag that we have
1402 found a declaration when we do. This is used to flag error 1529
1404 * driver.cs: Report ok when we display the help only.
1406 2002-07-06 Andrew Birkett <adb@tardis.ed.ac.uk>
1408 * cs-tokenizer.cs (xtoken): Improve handling of string literals.
1410 2002-07-04 Miguel de Icaza <miguel@ximian.com>
1412 * cs-tokenizer.cs (define): We also have to track locally the
1413 defines. AllDefines is just used for the Conditional Attribute,
1414 but we also need the local defines for the current source code.
1416 2002-07-03 Miguel de Icaza <miguel@ximian.com>
1418 * statement.cs (While, For, Do): These loops can exit through a
1419 Break statement, use this information to tell whether the
1420 statement is the last piece of code.
1422 (Break): Flag that we break.
1424 * codegen.cs (EmitContexts): New `Breaks' state variable.
1426 2002-07-03 Martin Baulig <martin@gnome.org>
1428 * class.cs (TypeContainer.MethodModifiersValid): Allow override
1429 modifiers in method declarations in structs. Otherwise, you won't
1430 be able to override things like Object.Equals().
1432 2002-07-02 Miguel de Icaza <miguel@ximian.com>
1434 * class.cs (Method, Property, Indexer): Do not allow the public
1435 modifier to be used in explicit interface implementations.
1437 (TypeContainer.MethodModifiersValid): Catch virtual, abstract and
1438 override modifiers in method declarations in structs
1440 2002-07-02 Andrew Birkett <adb@tardis.ed.ac.uk>
1442 * cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
1443 integer or real overflow, report an error
1445 2002-07-02 Martin Baulig <martin@gnome.org>
1447 * typemanager.cs (TypeManager.InitCoreTypes): When compiling
1448 corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
1449 to tell the runtime about our newly created System.Object and
1450 System.ValueType types.
1452 2002-07-02 Miguel de Icaza <miguel@ximian.com>
1454 * expression.cs (This): Use Stobj/Ldobj when we are a member of a
1455 struct instead of Ldarg/Starg.
1457 2002-07-02 Martin Baulig <martin@gnome.org>
1459 * expression.cs (Indirection.Indirection): Call
1460 TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
1462 2002-07-02 Martin Baulig <martin@gnome.org>
1464 * expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
1465 ValueType, call TypeManager.TypeToCoreType() on it.
1466 (Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
1467 the OpCodes.Newarr argument.
1469 2002-07-02 Martin Baulig <martin@gnome.org>
1471 * expression.cs (Invocation.EmitCall): When compiling corlib,
1472 replace all calls to the system's System.Array type to calls to
1473 the newly created one.
1475 * typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
1476 System.Array methods.
1477 (TypeManager.InitCoreTypes): When compiling corlib, get the methods
1478 from the system's System.Array type which must be replaced.
1480 Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
1482 * typemanager.cs: load unverifiable_code_ctor so we can build
1483 corlib using the correct type. Avoid using GetTypeCode() with
1485 * rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
1486 TypeManager.object_type to allow building corlib.
1488 Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
1490 * ecore.cs: handle System.Enum separately in LoadFromPtr().
1492 2002-07-01 Martin Baulig <martin@gnome.org>
1494 * class.cs: Make the last change actually work, we need to check
1495 whether `ifaces != null' to avoid a crash.
1497 Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
1499 * class.cs: when we build structs without fields that implement
1500 interfaces, we need to add the interfaces separately, since there is
1501 no API to both set the size and add the interfaces at type creation
1504 Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
1506 * expression.cs: the dimension arguments to the array constructors
1507 need to be converted if they are a long.
1509 Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
1511 * class.cs: don't emit ldarg.0 if there is no parent constructor
1512 (fixes showstopper for corlib).
1514 2002-06-29 Martin Baulig <martin@gnome.org>
1516 MCS now compiles corlib on GNU/Linux :-)
1518 * attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
1519 ie. check for MethodImplOptions.InternalCall.
1521 * class.cs (TypeContainer.DefineType): When compiling corlib, both parent
1522 and TypeManager.attribute_type are null, so we must explicitly check
1523 whether parent is not null to find out whether it's an attribute type.
1524 (Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
1525 and SetBuilder, not only if the property is neither abstract nor external.
1526 This is necessary to set the MethodImplOptions on the accessor methods.
1527 (Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
1528 SetBuilder, see Property.Emit().
1530 * rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
1531 populate "System.Object", "System.ValueType" and "System.Attribute" since
1532 they've already been populated from BootCorlib_PopulateCoreTypes().
1534 2002-06-29 Martin Baulig <martin@gnome.org>
1536 * ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
1537 is the NullLiteral, we also need to make sure that target_type is not
1540 2002-06-29 Martin Baulig <martin@gnome.org>
1542 * rootcontext.cs (RootContext.ResolveCore): We must initialize
1543 `TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
1544 before calling BootstrapCorlib_ResolveDelegate ().
1546 2002-06-27 Gonzalo Paniagua Javier <gonzalo@ximian.com>
1548 * statement.cs: fixed build-breaker. All tests passed ok.
1550 2002-06-27 Martin Baulig <martin@gnome.org>
1552 * typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
1553 for System.Decimal when compiling corlib.
1555 2002-06-27 Martin Baulig <martin@gnome.org>
1557 * statement.cs (Switch.TableSwitchEmit): Make this work with empty
1558 switch blocks which contain nothing but a default clause.
1560 2002-06-26 Andrew <adb@tardis.ed.ac.uk>
1562 * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
1564 2002-06-27 Martin Baulig <martin@gnome.org>
1566 * ecore.cs (PropertyExpr.PropertyExpr): Call
1567 TypeManager.TypeToCoreType() on the `pi.PropertyType'.
1569 * typemanager.cs (TypeManager.TypeToCoreType): Return if the type
1570 is already a TypeBuilder.
1572 2002-06-27 Martin Baulig <martin@gnome.org>
1574 * ecore.cs (Expression.ImplicitReferenceConversionExists): Use
1575 `target_type == TypeManager.array_type', not IsAssignableFrom() in
1576 the "from an array-type to System.Array" case. This makes it work
1577 when compiling corlib.
1579 2002-06-27 Martin Baulig <martin@gnome.org>
1581 * ecore.cs (Expression.SimpleNameResolve): If the expression is a
1582 non-static PropertyExpr, set its InstanceExpression. This makes
1583 the `ICollection.Count' property work in System/Array.cs.
1585 2002-06-25 Andrew Birkett <adb@tardis.ed.ac.uk>
1587 * driver.cs: Made error handling more consistent. Errors now
1588 tracked by Report class, so many methods which used to return int
1589 now return void. Main() now prints success/failure and
1590 errors/warnings message.
1592 Renamed '--probe' compiler argument to '--expect-error'. Removed
1593 the magic number return values (123 and 124). Now, if the
1594 expected error occurs, the compiler exits with success (exit value
1595 0). If the compilation completes without seeing that particular
1596 error, the compiler exits with failure (exit value 1). The
1597 makefile in mcs/errors has been changed to handle the new behaviour.
1599 * report.cs: Made 'expected error' number a property and renamed
1600 it from 'Probe' to 'ExpectedError'.
1602 * genericparser.cs: Removed error handling support, since it is
1603 now all done by Report class.
1605 * cs-parser.jay, mb-parser.jay: Errors are tracked by Report
1606 class, so parse() no longer returns an int.
1608 * namespace.cs: Use Report.Error instead of GenericParser.error
1610 2002-06-22 Miguel de Icaza <miguel@ximian.com>
1612 * class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
1613 TypeContainer.AddOperator): At the front of the list put the
1614 explicit implementations, so they get resolved/defined first.
1616 2002-06-21 Miguel de Icaza <miguel@ximian.com>
1618 * class.cs (TypeContainer.VerifyImplements): Verifies that a given
1619 interface type is implemented by this TypeContainer. Used during
1620 explicit interface implementation.
1622 (Property.Define, Indexer.Define, Method.Define): Validate that
1623 the given interface in the explicit implementation is one of the
1624 base classes for the containing type.
1626 Also if we are explicitly implementing an interface, but there is
1627 no match in the pending implementation table, report an error.
1629 (Property.Define): Only define the property if we are
1630 not explicitly implementing a property from an interface. Use the
1631 correct name also for those properties (the same CSC uses,
1632 although that is really not needed).
1634 (Property.Emit): Do not emit attributes for explicitly implemented
1635 properties, as there is no TypeBuilder.
1637 (Indexer.Emit): ditto.
1639 Hiding then means that we do not really *implement* a pending
1640 implementation, which makes code fail.
1642 2002-06-22 Martin Baulig <martin@gnome.org>
1644 * ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
1645 the return value of Object.GetType(). [FIXME: we need to do this whenever
1646 we get a type back from the reflection library].
1648 Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
1650 * typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
1652 2002-06-20 Miguel de Icaza <miguel@ximian.com>
1654 * attribute.cs: Return null if we can not look up the type.
1656 * class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
1657 the interface types found.
1659 * interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
1660 interface types found.
1662 * typemanager.cs (GetInterfaces): Make this routine returns alll
1663 the interfaces and work around the lame differences between
1664 System.Type and System.Reflection.Emit.TypeBuilder in the results
1665 result for GetInterfaces.
1667 (ExpandInterfaces): Given an array of interface types, expand and
1668 eliminate repeated ocurrences of an interface. This expands in
1669 context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
1672 2002-06-21 Martin Baulig <martin@gnome.org>
1674 * typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
1677 2002-06-21 Martin Baulig <martin@gnome.org>
1679 * typemanager.cs (TypeManager.TypeToCoreType): New function. When compiling corlib
1680 and called with one of the core types, return the corresponding typebuilder for
1683 * expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
1686 2002-06-21 Martin Baulig <martin@gnome.org>
1688 * ecore.cs (Expression.ExplicitReferenceConversionExists): Use
1689 `target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
1690 (Expression.ConvertReferenceExplicit): Likewise.
1692 * expression.cs (ElementAccess.DoResolve): Likewise.
1693 (ElementAccess.DoResolveLValue): Likewise.
1695 2002-06-10 Martin Baulig <martin@gnome.org>
1697 * interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
1698 add the "value" parameter to the parameter list.
1700 * statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
1703 2002-06-19 Miguel de Icaza <miguel@ximian.com>
1705 * expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
1706 the argument to an int, uint, long or ulong, per the spec. Also
1707 catch negative constants in array creation.
1709 Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
1711 * class.cs: do not allow the same interface to appear twice in
1712 the definition list.
1714 Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
1716 * ecore.cs: don't use ldlen with System.Array.
1718 Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
1720 * ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
1722 Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
1724 * modifiers.cs: produce correct field attributes for protected
1725 internal. Easy fix so miguel can work on ther harder stuff:-)
1727 2002-06-18 Miguel de Icaza <miguel@ximian.com>
1729 * pending.cs: New file. Move the code from class.cs here.
1730 Support clearning the pending flag for all methods (when not doing
1731 explicit interface implementation).
1733 Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
1735 * rootcontext.cs: added a couple more types needed to bootstrap.
1737 2002-06-17 Miguel de Icaza <miguel@ximian.com>
1739 * typemanager.cs (GetConstructor): Use DeclaredOnly to look the
1740 constructor in the type, instead of any constructor in the type
1741 hierarchy. Thanks to Paolo for finding this bug (it showed up as
1742 a bug in the Mono runtime when applying the params attribute).
1744 2002-06-16 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
1745 * changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
1747 2002-06-14 Rachel Hestilow <hestilow@ximian.com>
1749 * expression.cs (Unary.ResolveOperator): Use TypeManager
1750 to resolve the type.
1752 2002-06-13 Ravi Pratap <ravi@ximian.com>
1754 * cs-parser.jay (enum_member_declaration): Pass in the attributes
1757 * enum.cs (AddEnumMember): Add support to store the attributes associated
1758 with each member too.
1760 * attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
1761 field builders too - this takes care of the enum member case.
1763 2002-06-10 Rachel Hestilow <hestilow@ximian.com>
1765 * typemanager.cs (TypeManager.VerifyUnManaged): Allow
1766 address-of operator on both value types and pointers.
1768 2002-06-10 Martin Baulig <martin@gnome.org>
1770 * interface.cs (Interface.PopulateIndexer): Add the indexer's
1771 PropertyBuilder to the `property_builders' list.
1773 * expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
1774 (Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
1775 `lookup_type' and all its interfaces. Unfortunately, Type.FindMembers() won't
1776 find any indexers which are inherited from an interface.
1778 2002-06-09 Martin Baulig <martin@gnome.org>
1780 * const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
1781 the same type as the constant if necessary. There's also a test-130.cs
1784 * enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
1786 * typemanager.cs (TypeManager.ChangeType): Previously known as
1787 Enum.ChangeEnumType().
1789 2002-06-09 Martin Baulig <martin@gnome.org>
1791 * expression.cs (Cast.TryReduce): Added support for consts.
1793 2002-06-08 Ravi Pratap <ravi@ximian.com>
1795 * class.cs (Accessor): Hold attributes information so we can pass
1798 * cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
1799 Modify to pass in attributes attached to the methods.
1801 (add_accessor_declaration, remove_accessor_declaration): Ditto.
1803 * attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
1804 to handle the Accessor kind :-)
1806 * class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
1808 2002-06-08 Martin Baulig <martin@gnome.org>
1810 * expression.cs (Unary.TryReduceNegative): Added support for
1813 2002-06-08 Martin Baulig <martin@gnome.org>
1815 * enum.cs (Enum.LookupEnumValue): Don't report an error if the
1816 name can't be found in the `defined_names' - the caller will do a
1817 MemberLookup in this case and thus find methods in System.Enum
1818 such as Enum.IsDefined().
1820 2002-06-08 Martin Baulig <martin@gnome.org>
1822 * enum.cs (Enum.ChangeEnumType): This is a custom version of
1823 Convert.ChangeType() which works with TypeBuilder created types.
1824 (Enum.LookupEnumValue, Enum.Define): Use it here.
1826 * class.cs (TypeContainer.RegisterRequiredImplementations): Added
1827 `TypeBuilder.BaseType != null' check.
1828 (TypeContainer.FindMembers): Only lookup parent members if we
1829 actually have a parent.
1830 (Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
1831 (ConstructorInitializer.Resolve): Likewise.
1833 * interface.cs (Interface.FindMembers): Added
1834 `TypeBuilder.BaseType != null' check.
1836 * rootcontext.cs (RootContext.ResolveCore): Added
1837 "System.Runtime.CompilerServices.IndexerNameAttribute" to
1838 classes_second_stage.
1840 * typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
1841 debug_type and trace_type when compiling with --nostdlib.
1843 2002-06-07 Martin Baulig <martin@gnome.org>
1845 * class.cs (TypeContainer): Added `have_nonstatic_fields' field.
1846 (AddField): Set it to true when adding a non-static field.
1847 (DefineType): Use `have_nonstatic_fields' to find out whether we
1848 have non-static fields, not `Fields != null'.
1850 2002-06-02 Miguel de Icaza <miguel@ximian.com>
1852 * ecore.cs (SimpleNameResolve): Removed simple bug (we were
1853 dereferencing a null on the static-field code path)
1855 2002-05-30 Martin Baulig <martin@gnome.org>
1857 * codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
1858 to take command line arguments. Use reflection to call the new
1859 custom `Initialize' function on the symbol writer and pass it the
1860 command line arguments.
1862 * driver.cs (--debug-args): New command line argument to pass command
1863 line arguments to the symbol writer.
1865 2002-05-28 Miguel de Icaza <miguel@ximian.com>
1867 * assign.cs (DoResolve): Forgot to do the implicit conversion to
1868 the target type for indexers and properties. Thanks to Joe for
1871 2002-05-27 Miguel de Icaza <miguel@ximian.com>
1873 * typemanager.cs (MethodFlags): returns the method flags
1874 (Obsolete/ShouldIgnore) that control warning emission and whether
1875 the invocation should be made, or ignored.
1877 * expression.cs (Invocation.Emit): Remove previous hack, we should
1878 not do this on matching a base type, we should do this based on an attribute
1880 Only emit calls to System.Diagnostics.Debug and
1881 System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
1882 on the command line.
1884 * rootcontext.cs: Global settings for tracing and debugging.
1886 * cs-tokenizer.cs (define): New utility function to track
1887 defines. Set the global settings for TRACE and DEBUG if found.
1889 2002-05-25 Ravi Pratap <ravi@ximian.com>
1891 * interface.cs (Populate*): Pass in the TypeContainer as well as
1892 the DeclSpace as parameters so that we can create EmitContexts and
1893 then use that to apply attributes etc.
1895 (PopulateMethod, PopulateEvent, PopulateProperty)
1896 (PopulateIndexer): Apply attributes everywhere.
1898 * attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
1901 (ApplyAttributes): Update accordingly.
1903 We now apply interface attributes for all members too.
1905 2002-05-26 Miguel de Icaza <miguel@ximian.com>
1907 * class.cs (Indexer.Define); Correctly check if we are explicit
1908 implementation (instead of checking the Name for a ".", we
1909 directly look up if the InterfaceType was specified).
1911 Delay the creation of the PropertyBuilder.
1913 Only create the PropertyBuilder if we are not an explicit
1914 interface implementation. This means that explicit interface
1915 implementation members do not participate in regular function
1916 lookups, and hence fixes another major ambiguity problem in
1917 overload resolution (that was the visible effect).
1919 (DefineMethod): Return whether we are doing an interface
1922 * typemanager.cs: Temporary hack until we get attributes in
1923 interfaces (Ravi is working on that) and we get IndexerName
1924 support in interfaces.
1926 * interface.cs: Register the indexers as properties.
1928 * attribute.cs (Attribute.Resolve): Catch the error, and emit a
1929 warning, I have verified that this is a bug in the .NET runtime
1930 (JavaScript suffers of the same problem).
1932 * typemanager.cs (MemberLookup): When looking up members for
1933 interfaces, the parent of an interface is the implicit
1934 System.Object (so we succeed in searches of Object methods in an
1935 interface method invocation. Example: IEnumerable x; x.ToString
1938 2002-05-25 Miguel de Icaza <miguel@ximian.com>
1940 * class.cs (Event): Events should also register if they do
1941 implement the methods that an interface requires.
1943 * typemanager.cs (MemberLookup); use the new GetInterfaces
1946 (GetInterfaces): The code used to lookup interfaces for a type is
1947 used in more than one place, factor it here.
1949 * driver.cs: Track the errors at the bottom of the file, we kept
1952 * delegate.cs (NewDelegate.Emit): We have to emit a null as the
1953 instance if the method we are calling is static!
1955 2002-05-24 Miguel de Icaza <miguel@ximian.com>
1957 * attribute.cs (ApplyAttributes): Make this function filter out
1958 the IndexerName attribute (as that attribute in reality is never
1959 applied) and return the string constant for the IndexerName
1962 * class.cs (TypeContainer.Emit): Validate that all the indexers
1963 have the same IndexerName attribute, and if so, set the
1964 DefaultName attribute on the class.
1966 * typemanager.cs: The return value might contain other stuff (not
1967 only methods). For instance, consider a method with an "Item"
1968 property and an Item method.
1970 * class.cs: If there is a problem with the parameter types,
1973 2002-05-24 Ravi Pratap <ravi@ximian.com>
1975 * ecore.cs (ImplicitConversionExists): Wrapper function which also
1976 looks at user defined conversion after making a call to
1977 StandardConversionExists - we need this for overload resolution.
1979 * expression.cs : Update accordingly the various method calls.
1981 This fixes 2 bugs filed against implicit user defined conversions
1983 2002-05-22 Miguel de Icaza <miguel@ximian.com>
1985 * statement.cs: Track the result of the assignment.
1987 2002-05-21 Miguel de Icaza <miguel@ximian.com>
1989 * expression.cs (MemberAccess): Improved error reporting for
1990 inaccessible members.
1992 2002-05-22 Martin Baulig <martin@gnome.org>
1994 * makefile (mcs-mono2.exe): New target. This is mcs compiled with
1995 itself with debugging support.
1997 2002-05-22 Martin Baulig <martin@gnome.org>
1999 * typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
2000 Removed, this isn't needed anymore.
2002 2002-05-20 Martin Baulig <martin@gnome.org>
2004 * typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
2005 be underlying type for an enum.
2007 2002-05-20 Miguel de Icaza <miguel@ximian.com>
2009 * typemanager.cs (InitEnumUnderlyingTypes): New helper function
2010 that splits out the loading of just the core types.
2012 * rootcontext.cs (ResolveCore): Split the struct resolution in
2013 two, so we can load the enumeration underlying types before any
2016 * expression.cs (Is): Bandaid until we fix properly Switch (see
2017 bug #24985 for details).
2019 * typemanager.cs (ImplementsInterface): The hashtable will contain
2020 a null if there are no interfaces implemented.
2022 2002-05-18 Miguel de Icaza <miguel@ximian.com>
2024 * cs-parser.jay (indexer_declarator): It is fine to have array
2027 2002-05-17 Miguel de Icaza <miguel@ximian.com>
2029 * typemanager.cs: (RegisterBuilder): New function used to register
2030 TypeBuilders that implement interfaces. Since
2031 TypeBuilder.GetInterfaces (as usual) does not work with lame
2033 (AddUserType): register interfaces.
2035 (ImplementsInterface): Use the builder_to_ifaces hash if we are
2036 dealing with TypeBuilder. Also, arrays are showing up as
2037 SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
2038 methods can not be invoked on them!
2040 * ecore.cs (ExplicitReferenceConversionExists): Made public.
2041 (ImplicitReferenceConversionExists): Split out from
2042 StandardConversionExists.
2044 * expression.cs (As): We were only implementing one of the three
2045 cases for the as operator. We now implement them all.
2046 (Is): Implement the various other cases for Is as well.
2048 * typemanager.cs (CACHE): New define used to control if we want or
2049 not the FindMembers cache. Seems to have a negative impact on
2050 performance currently
2052 (MemberLookup): Nested types have full acess to
2053 enclosing type members
2055 Remove code that coped with instance/static returns for events, we
2056 now catch this in RealFindMembers.
2058 (RealFindMembers): only perform static lookup if the instance
2059 lookup did not return a type or an event.
2061 2002-05-17 Miguel de Icaza <miguel@ximian.com>
2063 * assign.cs (CompoundAssign): We pass more semantic information
2064 now to Compound Assignments than we did before: now we have all
2065 the information at hand, and now we resolve the target *before* we
2066 do the expression expansion, which allows the "CacheValue" method
2067 to have the effect we intended (before, a [x] += 1 would generate
2068 two differen ArrayAccess expressions from the ElementAccess,
2069 during the resolution process).
2071 (CompoundAssign.DoResolve): Resolve target and original_source here.
2073 2002-05-16 Miguel de Icaza <miguel@ximian.com>
2075 * expression.cs (ArrayAccess): dropped debugging information.
2077 * typemanager.cs: Small bug fix: I was always returning i_members,
2078 instead of one of i_members or s_members (depending on which had
2081 * assign.cs (IAssignMethod.CacheTemporaries): New method. This
2082 method is invoked before any code generation takes place, and it
2083 is a mechanism to inform that the expression will be invoked more
2084 than once, and that the method should use temporary values to
2085 avoid having side effects
2087 (Assign.Emit): Call CacheTemporaries in the IAssignMethod.
2089 * ecore.cs (Expression.CacheTemporaries): Provide empty default
2092 * expression.cs (Indirection, ArrayAccess): Add support for
2093 CacheTemporaries in these two bad boys.
2095 * ecore.cs (LoadFromPtr): figure out on our own if we need to use
2097 (StoreFromPtr): Handle stobj as well.
2099 * expression.cs (UnaryMutator): Share more code.
2101 * typemanager.cs (FindMembers): Thanks to Paolo for tracking this
2102 down: I was not tracking the Filter function as well, which
2103 was affecting the results of the cache.
2105 2002-05-15 Miguel de Icaza <miguel@ximian.com>
2107 * attribute.cs: Remove the hack to handle the CharSet property on
2110 2002-05-14 Miguel de Icaza <miguel@ximian.com>
2112 * attribute.cs (DoResolve): More uglyness, we now only try to
2113 resolve the attribute partially, to extract the CharSet
2114 information (only if we are a StructLayout attribute). Otherwise
2116 (GetExtraTypeInfo): Add some code to conditionally kill in the
2117 future this. I am more and more convinced that the .NET
2118 framework has special code to handle the attribute setting on
2121 * expression.cs (IsParamsMethodApplicable): Revert my previous
2122 foreach change here, it was wrong.
2124 2002-05-13 Miguel de Icaza <miguel@ximian.com>
2126 * cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
2127 (pp_expr): do not abort on unknown input, just return.
2128 (eval): abort if there are pending chars.
2130 * attribute.cs (Attribute.Resolve): Positional parameters are
2131 optional. Deal with that case.
2133 * class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
2134 the Ansi/Unicode/Auto information for the type.
2136 (TypeContainer.DefineType): instantiate the EmitContext here, as
2137 we will be using it during the type definition (to resolve
2138 attributes) and during the emit phase.
2140 * attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
2141 to pull type information out of the attributes
2143 (Attribute.Resolve): track the constructor builder, and allow for
2144 multiple invocations (structs and classes will use this).
2146 * ecore.cs (MemberLookupFinal): new version with all the
2147 parameters customizable.
2149 * expression.cs (New.DoResolve): Use MemberLookupFinal to locate
2150 constructors. Return if the result value is null (as the error
2151 would have been flagged already by MemberLookupFinal)
2153 Do not allow instances of abstract classes or interfaces to be
2156 * class.cs: (MethodSignature.InheritableMemberSignatureCompare):
2157 We have to compare the assembly property here when dealing with
2158 FamANDAssem and Assembly access modifiers, because we might be
2159 creating an assembly from *modules* (that means that we are not
2160 getting TypeBuilders for types defined in other modules that are
2161 part of this assembly).
2163 (Method.Emit): If the method is marked abstract and has a body,
2166 (TypeContainer.DefineMembers): If both the defined member and the
2167 parent name match are methods, then do not emit any warnings: let
2168 the Method.Define routine take care of flagging warnings. But if
2169 there is a mismatch (method overrides something else, or method is
2170 overriwritten by something, then emit warning).
2172 (MethodSignature.MemberSignatureCompare): If the sig.ret_type is
2173 set to null, this means `do not check for the return type on the
2176 (Method.Define): set the return type for the method signature to
2177 null, so that we get methods with the same name and parameters and
2178 different return types. This is used to flag warning 114 (you are
2179 hiding a method, and you probably want to use the new/override
2182 * typemanager.cs (MemberLookup): Implemented proper access
2183 control, closing a long standing set of bug reports. The problem
2184 was that the Framework only has two bits: Public and NonPublic,
2185 and NonPublic includes private and protected methods, but we need
2186 to enforce the FamANDAssem, FamOrAssem and Family.
2188 2002-05-11 Miguel de Icaza <miguel@ximian.com>
2190 * statement.cs (GotoCase): Return true: Ammounts to giving up
2191 knowledge on whether we return or not, and letting the other case
2192 be responsible for it.
2194 2002-05-10 Miguel de Icaza <miguel@ximian.com>
2196 * driver.cs: Do not load directories for each file processed, only
2197 do it if there is a pattern.
2199 * ecore.cs: Report readonly assigns here as well, as we might have
2200 been resolved only by MemberAccess.
2202 (SimpleName.SimpleNameResolve): Also be useful for LValue
2203 resolution. We need this to propagate assign to local readonly variables
2205 * typemanager.cs: Use a ptrhashtable for the criteria, because we
2206 do not want to reuse potential criteria memory.
2208 * class.cs (MyEventBuilder): Set reflected_type;
2210 * ecore.cs (Constantify): Added support for constifying bools.
2212 (RootContext.LookupType): Added a cache for values looked up in
2213 the declaration space.
2215 * typemanager.cs (FindMembers): Now is a front-end to
2216 RealFindMembers, and provides a two-level hashtable-based cache to
2219 15% performance improvement: from 22.5 to 19.2 seconds.
2221 * expression.cs (IsParamsMethodApplicable): use foreach.
2222 (Invocation.DoResolve): ditto.
2223 (New.DoResolve): ditto.
2224 (ArrayCreation.DoResolve): ditto.
2226 * ecore.cs (FindMostEncompassingType): use foreach.
2228 * delegate.cs (NewDelegate.DoResolve): Use foreach
2230 * ecore.cs (Expression.FindMostSpecificSource): Use foreach.
2231 (RemoveMethods): use foreach.
2233 * expression.cs (Invocation.MakeUnionSet): Optimization: Use two
2234 nested foreach statements instead of for, and also break out of
2235 the inner loop once a match is found.
2237 (Invocation.OverloadResolve): Use foreach, simplify the code.
2239 2002-05-08 Miguel de Icaza <miguel@ximian.com>
2241 * cfold.cs (BinaryFold): During an enumeration evaluation context,
2242 we actually unwrap the expression to allow for extra information
2245 * expression.cs: Use Shr_Un on unsigned operations.
2247 2002-05-08 Ravi Pratap <ravi@ximian.com>
2249 * ecore.cs (FindMostEncompass*): Fix trivial bug where the set of
2250 applicable operators was not being considered correctly. This closes
2251 the bug Miguel reported.
2253 Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
2255 * attribute.cs: check that the type derives from System.Attribute
2256 and report the correct error in that case (moved the duplicate code to
2257 its own method, too).
2259 Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
2261 * attribute.cs: lookup attribute type name as the spec says: first the
2262 bare attribute name and then name + "Attribute" (nant compiles with
2263 mcs after this fix).
2265 2002-05-07 Miguel de Icaza <miguel@ximian.com>
2267 * expression.cs (Unary.TryReduceNegative): Ah! Tricky! Tricky!
2268 Because of the way we parse things, we should try to see if a
2269 UIntConstant can fit in an integer.
2271 2002-05-07 Ravi Pratap <ravi@ximian.com>
2273 * ecore.cs (GetConversionOperators): Do not pick up op_True operators
2274 when we are in an explicit context.
2276 (ConvertReferenceExplicit): When converting from Iface type S to Class
2277 T make sure the rules are implemented as an OR.
2279 * parameter.cs (ParameterType): Make it a property for now although the
2280 purpose really isn't anything immediate.
2282 * expression.cs (Is*Applicable): Do better checking on the parameter type
2283 of a ref/out parameter. The ones from the system assemblies are already
2284 marked with the correct type so we don't need to do any correction.
2286 * ecore.cs (StandardConversionExists): Conversion from Interface types to
2287 the object type is standard too so include that.
2289 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2291 * ecore.cs (StandardConversionExists): Augment with missing code:
2292 deal with IntConstant, LongConstants and Enumerations.
2294 * assign.cs: Report the error, instead of failing silently
2296 * rootcontext.cs (AddGlobalAttributes): Track attributes on the
2297 typecontainer that they are declared, because the
2298 typecontainer/namespace will have the list of using clauses that
2301 Assembly Attributes were escaping the normal registration
2304 (EmitCode): Apply attributes within an EmitContext that represents
2305 the container they were declared on.
2307 * cs-parser.jay: Track bases for structs. How did I get this wrong?
2309 2002-05-06 Ravi Pratap <ravi@ximian.com>
2311 * ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
2312 Revamp completely - make much cleaner as we now operate only
2315 (FindMostSpecificSource, FindMostSpecificTarget): New methods
2316 to implement the logic detailed in the spec more correctly.
2318 (UserDefinedConversion): Update accordingly.
2320 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2322 * statement.cs: Return flow analysis information up.
2324 * cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
2327 (token): Do not consume an extra character before calling
2330 2002-05-06 Piers Haken <piersh@friskit.com>
2332 * cs-parser.jay: add 'override' attribute to System.Object.Finalize
2334 2002-05-06 Miguel de Icaza <miguel@ximian.com>
2336 * class.cs (Constructor.Emit): Set the IsStatic flag in the
2337 EmitContext during the instance constructor initializer
2338 resolution, to stop access to instance variables.
2340 This is mandated by the spec, last paragraph of the `constructor
2341 initializers' section.
2343 2002-05-05 Miguel de Icaza <miguel@ximian.com>
2345 * cs-parser.jay, class.cs (Accessor): new class used to represent
2346 an accessor (get or set). In the past we used `null' to represent
2347 a missing accessor. But this is ambiguous because there was no
2348 way to tell in abstract indexers/properties if one of them was
2351 Now there is a way of addressing that.
2353 * expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
2354 instead of FindMembers.
2356 * class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
2357 the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
2359 * attribute.cs: Treat indexers and properties as the same in terms
2360 of applying attributes
2362 * ecore.cs (FindMostEncompassedType): Use statically initialized
2363 EmptyExpressions()s like we do elsewhere to avoid creating useless
2364 objects (and we take this out of the tight loop).
2366 (GetConversionOperators): Move the code to extract the actual
2367 operators to a separate routine to clean things up.
2369 2002-05-04 Miguel de Icaza <miguel@ximian.com>
2371 * ecore.cs (FieldExpr): Remove un-needed tests for null, since now
2372 events are always registered FieldBuilders.
2374 * class.cs (FieldBase): New class shared by Fields
2376 * delegate.cs: If we are a toplevel delegate, use our full name.
2377 If we are a nested delegate, then only use our tail name.
2379 2002-05-02 Ravi Pratap <ravi@ximian.com>
2381 * expression.cs (IsApplicable): Ensure that we add the "&" to
2382 ref/out types before comparing it with the type of the argument.
2384 (IsParamsMethodApplicable): Ditto.
2386 (Argument.Type): Use TypeManager.LookupType instead of Type.GetType -
2389 * delegate.cs : Handle the case when we have more than one applicable
2390 method. Flag an error only when we finish checking all.
2392 2002-05-02 Miguel de Icaza <miguel@ximian.com>
2394 * expression.cs: Add support for boolean static initializers.
2396 2002-05-01 Miguel de Icaza <miguel@ximian.com>
2398 * attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
2400 * parameter.cs (ComputeParameterTypes,
2401 ComputeAndDefineParameterTypes): Better error handling: now we
2402 clear the `types' cache if we fail during any of the type lookups.
2403 We also return the status code correctly to our caller
2405 * delegate.cs: If we fail to define a delegate, abort the extra
2408 * expression.cs (Binary.ResolveOperator): for
2409 operator==(object,object) and operator !=(object, object) we also
2410 have to verify that there is an implicit conversion from one to
2413 (ArrayAccess.DoResolve): Array Access can operate on
2416 2002-04-30 Miguel de Icaza <miguel@ximian.com>
2418 * assign.cs (CompoundAssign): A new class used as a "flag" that
2419 the assignment actually is happening as part of a compound
2420 assignment operator.
2422 During compound assignment, a few new rules exist to enable things
2429 x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
2430 to the type of x) if y is implicitly convertible to the type of x,
2431 and the operator is a builtin operator and the return type of the
2432 operator is explicitly convertible to the type of x.
2434 * rootcontext.cs: Reset warning level to 2. 4 catches various
2435 "interesting" features in mcs, we must clean this up at some
2436 point, but currently am trying to kill other bugs ;-)
2438 * ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
2439 in container classes as well.
2441 * expression.cs (Binary.ResolveOperator): Handle string case
2442 before anything else (as operator overloading does emit an error
2443 before doing anything else).
2445 This code could go away when we move to a table driven model, but
2446 i could not come up with a good plan last night.
2448 2002-04-30 Lawrence Pit <loz@cable.a2000.nl>
2450 * typemanager.cs (CSharpName): reimplementation using regex.
2451 * class.cs: added null check for fields in Emit
2452 * rootcontext.cs: set warninglevel to 4
2454 2002-04-29 Miguel de Icaza <miguel@ximian.com>
2456 * typemanager.cs (CSharpName): reimplemented with Lupus
2459 2002-04-28 Miguel de Icaza <miguel@ximian.com>
2461 * statement.cs (If): correclty implement Resolve, because we were
2462 not catching sem errors in there. The same process is needed
2464 (Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
2467 (Statement.Warning_DeadCodeFound): Factorize code.
2468 (While): Report dead code here too.
2470 (Statement): Added Resolve virtual method to allow
2471 for resolution split from the emit code.
2473 2002-04-26 Miguel de Icaza <miguel@ximian.com>
2475 * statement.cs (EmitBoolExpression): No longer try to resolve the
2477 (MakeBoolean): New utility function that resolve, implicitly
2478 converts to boolean and tags the expression.
2481 (If, Do): Implement dead code elimination.
2482 (While): Implement loop inversion
2484 (Do, While, For, If): Resolve the expression prior to calling our
2487 2002-04-22 Lawrence Pit <loz@cable.a2000.nl>
2490 - added method Report28 (warning: program has more than one entry point)
2491 - added method IsEntryPoint, implements paragraph 10.1 of the spec
2492 - modified method Method.Define, the part at the end of the method
2494 * rootcontext.cs: added static public Location EntryPointLocation;
2496 * ../errors/cs0028.cs : Add test case for the above warning.
2499 - modified method CSharpName to allow arrays of primitive type to
2500 be printed nicely (e.g. instead of System.Int32[][] it now prints
2502 - added method CSharpSignature: returns the signature of a method
2503 in string format to be used in reporting errors, warnings, etc.
2505 * support.cs: InternalParameters.ParameterDesc variable tmp initialized
2508 2002-04-26 Ravi Pratap <ravi@ximian.com>
2510 * delegate.cs (Define): Fix extremely silly bug where I was
2511 setting the type of the 'object' parameter of the BeginInvoke
2512 method to System.IAsyncResult instead of System.Object ;-)
2514 2002-04-26 Miguel de Icaza <miguel@ximian.com>
2516 * class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
2519 (Constructor.Emit): return if we fail to initialize the
2520 constructor. Another door closed!
2522 * expression.cs (New.DoResolve): Improve error message (from -6 to
2523 1501). Use DeclaredOnly lookup to find the exact constructor.
2525 * typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
2526 loop. This is useful.
2528 * cs-parser.jay: Adjust the default parameters so that destructors
2529 have the proper signature.
2531 2002-04-26 Martin Baulig <martin@gnome.org>
2533 * driver.cs (LoadAssembly): If `assembly' contains any characters
2534 which are only valid in path names and not in assembly names
2535 (currently slash, backslash and point), use Assembly.LoadFrom ()
2536 instead of Assembly.Load () on the `assembly' (before iteration
2537 over the link_paths).
2539 2002-04-26 Martin Baulig <martin@gnome.org>
2541 * cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
2543 2002-04-25 Miguel de Icaza <miguel@ximian.com>
2545 * class.cs (Property): use the new typemanager.MemberLookup
2547 (TypeContainer.MemberLookup): Implement using the
2548 TypeManager.MemberLookup now.
2550 * typemanager.cs: Make MemberLookup a function of the TypeManager,
2551 and return MemberInfos, so that these can be used without an
2552 EmitContext (what we had before).
2554 2002-04-24 Miguel de Icaza <miguel@ximian.com>
2556 * expression.cs: Fix the case where the argument to params if the
2557 type of the params. I omitted handling this before. Fixed
2559 2002-04-22 Miguel de Icaza <miguel@ximian.com>
2561 * driver.cs: Call BootCorlib_PopulateCoreType
2563 * class.cs (Property.CheckBase): Check for properties only, not
2566 * interface.cs: Temporary hack: try/catch around the
2567 CustomAttributeBuilder, because I am getting an exception that I
2570 * rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
2571 types whose definitions are required to be there (attributes are
2572 defined before standard types).
2574 Compute definitions as we boot the various types, as they are used
2575 immediately (value_type class will need object_type, but if we do
2576 not initialize object_type, we will pass a null, which will let
2577 the runtime pick the System.Object from the existing corlib, which
2578 is not what we want).
2580 2002-04-22 Patrik Torstensson <totte@labs2.com>
2582 * cs-tokenizer.cs: fixed a number of trim() issues.
2584 2002-04-22 Ravi Pratap <ravi@ximian.com>
2586 * expression.cs (Argument.Type): Ensure that we return the correct
2587 type when we have out or ref parameters [in which case we
2590 2002-04-22 Miguel de Icaza <miguel@ximian.com>
2592 * class.cs (Property, Indexer): Allow extern modifier in there.
2594 * typemanager.cs (InitBaseTypes): Initializes object_type and
2595 value_type, since those will be used early on during the bootstrap
2596 process to compile corlib.
2598 (InitCoreTypes): Move code from here to InitBaseTypes.
2600 2002-04-21 Miguel de Icaza <miguel@ximian.com>
2602 * ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
2603 single-dimension arrays as using the ldlen opcode.
2605 Daniel Lewis discovered this optimization.
2607 * typemanager.cs: Add signature for System.Array::get_Length
2609 2002-04-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2611 * statement.cs: report the error when the foreach does not apply to an
2612 array nor a collection.
2614 2002-04-19 Miguel de Icaza <miguel@ximian.com>
2616 * expression.cs: Add implicit conversions to the operator ~.
2618 * constant.cs (DecimalConstant.Emit): Emit decimal value.
2620 * typemanager.cs: Locate the decimal constructor.
2622 2002-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2624 * attribute.cs: use the new property of TypeOf.
2625 * expression.cs: added 'get' property around typearg.
2627 These changes fix a build breaker reported by NickD. Is this the
2628 correct way to fix? If not, please, revert my changes and make it
2631 2002-04-17 Miguel de Icaza <miguel@ximian.com>
2633 * attribute.cs: Add support for typeof in attribute invocations.
2634 I am not sure that this is right though.
2636 2002-04-14 Duncan Mak <duncan@ximian.com>
2638 * cfold.cs (BinaryFold): Catch DivideByZeroException in the
2639 Binary.Operator.Division case.
2641 2002-04-13 Ravi Pratap <ravi@ximian.com>
2643 * class.cs (DefineType): Ensure that we do a proper check on
2644 attribute types and also register it with the TypeManager.
2646 (TypeContainer.Targets): The default for attribute types is
2647 AttributeTargets.All.
2649 * attribute.cs (ApplyAttributes): Registering the attribute type
2650 is done elsewhere, not when we discover we have a Usage attribute.
2652 2002-04-12 Ravi Pratap <ravi@ximian.com>
2654 * expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
2655 and get rid of is_delegate parameter.
2657 * everywhere : update.
2659 2002-04-12 Ravi Pratap <ravi@ximian.com>
2661 * cs-parser.jay (compilation_unit): Revamp completely to use
2662 some new ideas that I got from Rhys' grammar to solve the problems
2663 with assembly level attributes.
2665 (outer_declaration): New grammar production.
2667 (attribute_sections): Add.
2669 (opt_attributes): Base on attribute_sections
2671 (namespace_declaration): Allow opt_attributes to tackle the case
2672 when we have assembly level attributes - we are clever in this
2675 * attribute.cs (ApplyAttributes): Do not worry about assembly
2676 attributes in the non-global context.
2678 * rootcontext.cs (AddGlobalAttributes): Go back to using this
2679 instead of SetGlobalAttributes.
2681 * class.cs, rootcontext.cs : Ensure we define and generate
2682 attribute types before anything else.
2684 * attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
2685 and flag the new error -20 for the case when the attribute type
2686 does not have valid targets specified. csc does not catch this.
2688 * ../errors/errors.txt : update for error # -20
2690 2002-04-11 Ravi Pratap <ravi@ximian.com>
2692 * support.cs (InternalParameters.ParameterModifier): Do some null
2693 checking and return sane values.
2695 * class.cs (Method.Define): If we are a PInvoke method, ensure
2696 that we are static and extern. Report error # 601
2698 * ../errors/cs0601.cs : Add test case for the above error.
2700 2002-04-07 Ravi Pratap <ravi@ximian.com>
2702 * rootcontext.cs (attribute_types): We need to keep type of
2703 all attribute types separately and emit code for them first.
2705 (RegisterAttribute) : Implement.
2707 * class.cs (DefineType): Check if the current Type is a custom
2708 attribute type and register it accordingly.
2710 * rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
2711 adding the first attribute twice and rename to
2713 (SetGlobalAttributes): this.
2715 * rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
2718 * attribute.cs (ApplyAttributes): Take an additional argument telling us
2719 if we are processing global arguments. Hmm, I am unsure of this.
2721 2002-04-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
2723 * expression.cs: added static array of strings to avoid calling
2724 Enum.ToString () for Operator in Binary. Significant recover of
2727 2002-04-10 Miguel de Icaza <miguel@ximian.com>
2729 * class.cs (FindMembers): Allow the Builders of the various
2730 members to be null. If they are skip them. This only happens
2731 during the PInvoke declaration.
2733 2002-04-09 Miguel de Icaza <miguel@ximian.com>
2735 * parameter.cs (Parameters.ComputeParameterTypes): Flag the
2736 failure, so we do not keep going afterwards.
2738 * expression.cs: (Invocation.OverloadResolve): I believe Ravi
2739 wanted to pass `false' as the `is_delegate' argument. If this is
2740 the case, why not use delegate_type == null to mean `is_delegate =
2741 false' and anything else as is_delegate = true.
2743 Tue Apr 9 05:40:12 2002 Piers Haken <piersh@friskit.com>
2745 * statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
2746 code for the section, not the beginning of the tests.
2748 2002-04-08 Miguel de Icaza <miguel@ximian.com>
2750 * cfold.cs: Handle operator + (Enum x, Underlying x)
2752 * expression.cs (Binary): same. Warn about errors where we have
2753 Enum/Enum in operator + as well.
2755 Mon Apr 8 06:29:03 2002 Piers Haken <piersh@friskit.com>
2758 - added support for switch(bool)
2759 - optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
2760 - add TableSwitchEmit() to handle table-based switch statements
2762 2002-04-05 Ravi Pratap <ravi@ximian.com>
2764 * expression.cs (Invocation.OverloadResolve): Factor out code which
2765 does parameter compatibility checking with arguments so that we can
2766 re-use the code even from Delegate.VerifyApplicability
2768 (VerifyArgumentsCompat): Move above code here.
2770 * delegate.cs (VerifyApplicability): Get rid of duplicate code
2771 and instead make a call to the above method.
2773 2002-03-31 Ravi Pratap <ravi@ximian.com>
2775 * typemanager.cs (attribute_type): Corresponds to System.Attribute.
2776 We use it to keep track of classes which are attribute types.
2778 2002-04-02 Miguel de Icaza <miguel@ximian.com>
2780 * delegate.cs (Delegate.Define): Correctly define the types in the
2781 presence of fixed and array parameters.
2783 * class.cs (TypeContainers.FindMembers): Use NonPublic flag while
2786 * ecore.cs (Expression.MemberLookup): Reset binding flags to not
2787 include NonPublic after the first iteration.
2789 * class.cs (Indexer.CheckBase): Only check if both parents are
2792 * cs-parser.jay (accessor_body): If empty, set to null.
2794 * ecore.cs (SimpleName.SimpleNameResolve): We did not have the
2795 same code path here to resolve constants names that we did have in
2796 MemberAccess.DoResolve. There is too much code duplicated here.
2798 2002-04-01 Miguel de Icaza <miguel@ximian.com>
2800 * statement.cs, makefile: Drop Statementcollection and just use ArrayLists
2802 * ecore.cs: Optimize UserDefinedConversion by minimizing the calls
2805 * cs-tokenizer.cs: Reuse a single StringBuilder for assembling
2806 tokens, numbers and strings.
2808 * ecore.cs (MethodGroupExpr): Make Emit warn about missing
2811 * delegate.cs: Use ComputeAndDefineParameterTypes for both the
2812 asyncronous parameters and the regular parameters.
2814 * codegen.cs (CodeGen.Init): Use the constructor that allows us to
2815 specify the target directory.
2817 * expression.cs: (This.DoResolve): Simplify
2818 (As.Emit): Optimize, do not generate IsInst if the expression is
2819 always of the given type.
2821 (Is.DoResolve): Bug fix, we were reporting both always/never for
2824 * (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
2825 creating too many unnecessary arrays.
2827 2002-03-31 Miguel de Icaza <miguel@ximian.com>
2829 * class.cs (EmitFieldInitializer): Use Assign expression to assign
2830 fields instead of rolling our own initializer. Takes care of all
2831 implicit conversions, and drops unnecessary static checks/argument.
2833 2002-03-31 Dick Porter <dick@ximian.com>
2835 * driver.cs: use the GetDirectories() return values properly, and
2836 use "/" as path separator.
2838 2002-03-30 Miguel de Icaza <miguel@ximian.com>
2840 * expression.cs (Unary): Optimize - - expr into expr.
2841 (Binary): Optimize a + (-b) into a -b.
2843 * codegen.cs (CodeGen): Made all methods static.
2845 2002-03-29 Miguel de Icaza <miguel@ximian.com>
2849 * decl.cs: Rename `definition' into `TypeBuilder' and drop the
2850 TypeBuilder property.
2852 * cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
2855 * tree.cs: Removed the various RecordXXXX, and replaced with a
2856 single RecordDecl. Removed all the accessor methods, and just
2857 left a single access point Type
2859 * enum.cs: Rename DefineEnum to DefineType.
2861 * decl.cs: New abstract method `DefineType' used to unify the
2862 Defines for Enumerations, Interfaces, TypeContainers and
2865 (FindType): Moved LookupInterfaceOrClass here. Moved the
2866 LookupBaseClasses method that used to live in class.cs and
2867 interface.cs here, and renamed to FindType.
2869 * delegate.cs: Implement DefineType. Take advantage of the
2870 refactored pattern for locating the parent builder without taking
2871 the parent_builder argument (which we know does not work if we are
2872 nested, and triggering a toplevel definition).
2874 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2876 * decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
2877 accessibility of a member has changed during override and report
2880 * class.cs (Method.Define, Property.Define): Only complain on
2881 overrides if the method is private, any other accessibility is
2882 fine (and since we just checked the permission is the same, we are
2885 * cs-tokenizer.cs: only line, region, endregion, if, endif, else
2886 and elif are processed always. The other pre-processing
2887 directives are only processed if we are "taking" the path
2889 2002-03-29 Martin Baulig <martin@gnome.org>
2891 * class.cs (Method.Emit): Only emit symbolic debugging info if the
2892 current location is not Null.
2894 * codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
2895 a separate method so we can profile it.
2897 * driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
2898 `span.Seconds' are just seconds, but no minutes or hours.
2899 (MainDriver): Profile the CodeGen.SaveSymbols calls.
2901 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2903 * class.cs (Method.Define), (Property.Define), (Indexer.Define):
2904 Remove the gratuitous set of Final:
2906 // If an interface implementation, then we can set Final.
2907 if (((flags & MethodAttributes.Abstract) == 0) &&
2908 implementing.DeclaringType.IsInterface)
2909 flags |= MethodAttributes.Final;
2911 I do not know what I was smoking when I used that.
2914 * cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
2915 step into fixing the name resolution issues for delegates and
2916 unifying the toplevel name resolution.
2918 2002-03-28 Martin Baulig <martin@gnome.org>
2920 * class.cs (Method.Emit): If we have a symbol writer, call its
2921 OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
2922 tell it about the current method.
2924 * codegen.cs (EmitContext.Mark): New public method. Tell the symbol
2925 writer that we're going to emit the first byte of IL code for a new
2926 statement (a new source line).
2927 (EmitContext.EmitTopBlock): If we have a symbol writer, call
2928 EmitContext.Mark() before emitting any code.
2930 * location.cs (SymbolDocument): Return null when we're Null.
2932 * statement.cs (Statement): Moved the `Location loc' variable here.
2933 (Statement.EmitBoolExpression): If we have a symbol writer, call
2934 ec.Mark() before emitting any code to tell it that we're at the
2935 beginning of a new statement.
2936 (StatementExpression): Added `Location' argument to the constructor.
2937 (Block): Added public readonly variable `StartLocation' and public
2938 variable `EndLocation'. The latter is to be set using SetEndLocation().
2939 (Block): Added constructor which takes a start and end location.
2940 (Block.SetEndLocation): New method. This sets the end location.
2941 (Block.EmitMeta): If we have a symbol writer, tell it the names of the
2942 local variables we create.
2943 (Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
2944 each statement and do also mark the begin and end of the block.
2946 * cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
2947 tell it the current lexer.Location, use Location.Null for the end of the
2949 (block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
2950 current block, set its end location using SetEndLocation().
2951 (statement_expression): StatementExpression constructor now takes the
2952 lexer.Location as additional argument.
2953 (for_statement, declare_local_variables): Likewise.
2954 (declare_local_variables): When creating a new implicit block, use the
2955 new Block constructor and pass it the lexer.Location.
2957 2002-03-28 Miguel de Icaza <miguel@ximian.com>
2959 * ecore.cs (Expression.MemberLookup): On interfaces, lookup
2960 members also on the parent interfaces recursively.
2962 2002-03-27 Miguel de Icaza <miguel@ximian.com>
2964 * report.cs: Use new formats, since Gonzalo finished the missing
2967 * expression.cs (Binary.ResolveOperator): added missing operator|
2968 operator& and operator^ for bool/bool.
2970 * cs-parser.jay: CheckDef now takes a Location argument that is
2971 used to report errors more precisly (instead of reporting the end
2972 of a definition, we try to track something which is a lot closer
2973 to the source of the problem).
2975 * cs-tokenizer.cs: Track global token use, so we can properly flag
2976 the use of #define/#undef after the first token has been seen.
2978 Also, rename the reportXXXX to Error_DescriptiveName
2980 * decl.cs (DeclSpace.IsTopLevel): Move property here from
2981 TypeContainer, so that Enum and Interface can use this too.
2983 * class.cs (TypeContainer.LookupInterfaceOrClass,
2984 GetInterfaceOrClass, GetClassBases, DefineType): Drop the
2985 `builder' argument. Typically this was used to pass the parent
2986 builder (a ModuleBuilder or a TypeBuilder from whoever triggered
2989 The problem is that a nested class could trigger the definition of
2990 a toplevel class, and the builder would be obviously wrong in that
2993 So we drop this argument, and we compute dynamically the
2994 TypeBuilder/ModuleBuilder (the correct information was available
2995 to us anyways from DeclSpace.Parent)
2997 * interface.cs (Interface.DefineInterface): Drop builder
2998 parameter cleanup like class.cs
3000 * enum.cs (Enum.DefineEnum): Drop builder parameter. Clean up
3003 * statement.cs (Switch.EmitObjectInteger): Emit short/ushort
3006 (Try.Emit): Propagate the returns value from the statement.
3008 (Return.Emit): Even if we are leavning
3010 * driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
3012 * modifiers.cs: Fix the computation of MethodAttributes flags.
3014 Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
3016 * driver.cs: allow compilation of files that start with '/'.
3017 Add a default case when checking the argument of --target.
3019 2002-03-25 Miguel de Icaza <miguel@ximian.com>
3021 * interface.cs: Implement the same search algorithm for types in
3024 * delegate.cs: Do not allow multiple definition.
3026 * Recovered ChangeLog that got accidentally amputated
3028 * interface.cs (Interface.DefineInterface): Prevent from double definitions.
3030 * rootcontext.cs: Load manually enum to allow core classes to
3031 contain enumerations.
3033 * enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
3034 Update to new static methods in TypeManager.
3036 * typemanager.cs (GetMethod, GetConstructor): Use our
3037 implementation of FindMembers to find the members, since during
3038 corlib compilation, the types are TypeBuilders and GetMethod and
3039 GetConstructor do not work.
3041 Make all methods in TypeManager static.
3043 (InitCodeHelpers): Split the functionality from
3044 the InitCodeTypes function.
3046 * driver.cs: Call InitCodeHelpers after we have populated the
3049 * cs-parser.jay (delegate_declaration): we did not used to compute
3050 the delegate name correctly for void delegates.
3052 2002-03-24 Miguel de Icaza <miguel@ximian.com>
3054 * rootcontext.cs (RootContext): Init the interface_resolve_order
3055 and type_container_resolve_order always.
3057 (ResolveCore, BootstrapCorlib_ResolveClass,
3058 BootstrapCorlib_ResolveStruct): New functions to bootstrap the
3059 compiler when compiling with --nostdlib
3061 * class.cs (TypeContainer.DefineType): Check that our parent is
3062 not null. This test is most important when we are bootstraping
3065 * codegen.cs: Split out the symbol writing code.
3067 2002-03-25 Martin Baulig <martin@gnome.org>
3069 * driver.cs (-g): Made -g an alias for --debug.
3071 2002-03-24 Martin Baulig <martin@gnome.org>
3073 * codegen.cs (SymbolWriter): New public variable. Returns the
3074 current symbol writer.
3075 (CodeGen): Added `bool want_debugging_support' argument to the
3076 constructor. If true, tell the ModuleBuild that we want debugging
3077 support and ask it for the ISymbolWriter.
3078 (Save): If we have a symbol writer, call it's Close() method after
3079 saving the assembly.
3081 * driver.c (--debug): New command line argument to create a
3082 debugger information file.
3084 * location.cs (SymbolDocument): New public property. Returns an
3085 ISymbolDocumentWriter object for the current source file or null
3086 if we don't have a symbol writer.
3088 2002-03-21 Miguel de Icaza <miguel@ximian.com>
3090 * driver.cs (LoadAssembly): Correctly return when all the paths
3091 have been tried and not before.
3093 * statement.cs (Switch.Emit): return the actual coverage for this
3094 statement (returns/not-returns)
3096 (Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
3097 switch of the statement if we are the last switch section. That
3098 kills two problems: try/catch problems (we used to emit an empty
3099 nop at the end) and switch statements where all branches would
3102 2002-03-19 Miguel de Icaza <miguel@ximian.com>
3104 * driver.cs: Add default assemblies (the equivalent to the
3105 Microsoft CSC.RSP file)
3107 * cs-tokenizer.cs: When updating `cols and setting it to zero,
3108 also update tokens_seen and set it to false.
3110 * driver.cs: Implement --recurse for Mike.
3112 * driver.cs (SplitPathAndPattern): Small bug fix, I was not
3113 correctly splitting out the paths.
3115 2002-03-18 Miguel de Icaza <miguel@ximian.com>
3117 * interface.cs (Interface.PopulateProperty): Instead of using
3118 `parent' as the declaration space for the set parameters, use
3121 * support.cs (InternalParameters): InternalParameters constructor
3122 takes a DeclSpace instead of a TypeContainer.
3124 * expression.cs (ArrayCreation.EmitDynamicInitializers): If value
3125 types are being initialized, load the address of it before calling
3128 (New): Provide a mechanism to disable the generation of local
3129 value type temporaries when the caller will be providing us with
3130 an address to store it.
3132 (ArrayCreation.EmitDynamicInitializers): Use it.
3134 2002-03-17 Miguel de Icaza <miguel@ximian.com>
3136 * expression.cs (Invocation.EmitArguments): Only probe for array
3137 property if there is more than one argument. Sorry about that.
3139 * class.cs (Invocation.EmitArguments): Fix to emit arguments for
3142 * class.cs (Method.LabelParameters): Fix incorrect code path that
3143 prevented the `ParamArrayAttribute' from being applied to the
3146 2002-03-16 Miguel de Icaza <miguel@ximian.com>
3148 * support.cs (ReflectionParameters): Correctly compute whether the
3149 last argument is a params array. Fixes the problem with
3152 * typemanager.cs: Make the assemblies array always be non-null
3153 (empty, but non-null)
3155 * tree.cs (RecordDecl): New function that abstracts the recording
3156 of names. This reports error 101, and provides a pointer to the
3157 previous declaration. Fixes a crash in the compiler.
3159 * cs-parser.jay (constructor_declaration): Update to new grammar,
3160 and provide a constructor_body that can be empty.
3162 2002-03-15 Miguel de Icaza <miguel@ximian.com>
3164 * driver.cs: Add support for --resources.
3166 * expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
3167 Make all types for the various array helper methods be integer.
3169 * ecore.cs (Expression.ConvertNumericExplicit): Pass the
3170 CheckState to ConvCast.
3172 (ConvCast): Now it takes a `checked' state argument, to avoid
3173 depending on the emit context for the conversion, and just using
3174 the resolve time setting.
3176 * expression.cs (ArrayCreation.EmitArrayArguments): New function,
3177 instead of Invocation.EmitArguments. We do not emit the original
3178 arguments, instead we emit those which have been converted to
3179 unsigned int expressions.
3181 * statement.cs (Block.EmitMeta): Drop tracking of indexes.
3183 * codegen.cs: ditto.
3185 * expression.cs (LocalVariableReference): Drop the use of the
3186 Store function that depended on the variable index.
3188 * statement.cs (VariableInfo): Drop the `Idx' property from this
3189 class, as this is not taking into account the indexes for
3190 temporaries tat we generate during the execution, getting the
3193 * class.cs: First emit class initializers, then call the parent
3196 * expression.cs (Binary): Fix opcode emision.
3197 (UnaryMutator.EmitCode): Support checked code generation
3199 * ecore.cs (MemberLookup): TypeManager.FindMembers will return
3200 matches for events for both the Static and Instance scans,
3201 pointing to the same element. Fix that.
3203 2002-03-14 Miguel de Icaza <miguel@ximian.com>
3205 * rootcontext.cs (ResolveTree): Always set the
3206 interface_resolve_order, because nested interfaces will be calling
3209 * class.cs (GetInterfaceOrClass): Track the same resolution
3210 process used by TypeManager.LookupType. This fixes the nested
3211 type lookups in class declarations (separate path from
3214 (TypeContainer.DefineType): Also define nested interfaces.
3215 (TypeContainer.RegisterOrder): New public function used to
3216 register the order in which child interfaces need to be closed.
3218 Nested interfaces need to be closed after their parents have been
3221 * interface.cs (InterfaceAttr): Put all the logic for computing
3222 the interface attribute here.
3224 (DefineInterface): Register our interface order with the
3225 RootContext or with the TypeContainer depending on the case.
3227 2002-03-12 Miguel de Icaza <miguel@ximian.com>
3229 * cs-parser.jay: rework foreach statement to work with the new
3230 changes to the policy on SimpleNames.
3232 * report.cs: support Stacktrace on warnings as well.
3234 * makefile: drop --unsafe and /unsafe from the compile.
3236 2002-03-13 Ravi Pratap <ravi@ximian.com>
3238 * ecore.cs (StandardConversionExists): Modify to take an Expression
3239 as the first parameter. Ensure we do null -> reference type conversion
3242 * Everywhere : update calls accordingly, making use of MyEmptyExpr to store
3243 temporary Expression objects.
3245 Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
3247 * interface.cs: workaround bug in method overloading resolution
3248 (there is already a bugzilla bug for it).
3250 2002-03-12 Miguel de Icaza <miguel@ximian.com>
3252 We could also solve this problem by having a separate path for
3253 performing type lookups, instead of DoResolve, we could have a
3254 ResolveType entry point, and only participating pieces of the
3255 production (simplename, deref, array) would implement this.
3257 * codegen.cs (EmitContext): New field OnlyLookupTypes used to
3258 signal SimpleName to only resolve type names and not attempt to
3259 resolve anything else.
3261 * expression.cs (Cast): Set the flag.
3263 * ecore.cs (SimpleName): Use the OnlyLookupTypes flag
3265 * class.cs: Only report 108 if there is no `new' modifier.
3267 * cs-parser.jay: rework foreach statement to work with the new
3268 changes to the policy on SimpleNames.
3270 * report.cs: support Stacktrace on warnings as well.
3272 * makefile: drop --unsafe and /unsafe from the compile.
3274 2002-03-11 Miguel de Icaza <miguel@ximian.com>
3276 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
3277 lookups here, instead of doing that at parse time. This means
3278 that our grammar will not introduce `LocalVariableReferences' as
3279 expressions at this point. That solves the problem of code like
3287 This is only half the fix. The full fix requires parameters to
3288 also be handled in this way.
3290 * Everywhere: Use ec.DeclSpace on calls to LookupType, as this
3291 makes the use more obvious of the DeclSpace. The
3292 ec.TypeContainer.TypeBuilder is now only used to pull the
3295 My theory is that I can get rid of the TypeBuilder completely from
3296 the EmitContext, and have typecasts where it is used (from
3297 DeclSpace to where it matters).
3299 The only pending problem is that the code that implements Aliases
3300 is on TypeContainer, and probably should go in DeclSpace.
3302 * ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
3303 lookups here, instead of doing that at parse time. This means
3304 that our grammar will not introduce `LocalVariableReferences' as
3305 expressions at this point. That solves the problem of code like
3313 This is only half the fix. The full fix requires parameters to
3314 also be handled in this way.
3316 * class.cs (Property.DefineMethod): When implementing an interface
3317 method, set newslot, when implementing an abstract method, do not
3318 set the flag (before we tried never setting it, or always setting
3319 it, which is the difference).
3320 (Indexer.DefineMethod): same.
3321 (Method.DefineMethod): same.
3323 * ecore.cs: Only set the status used flag if we get back a Field.
3325 * attribute.cs: Temporary hack, so Paolo can keep working.
3327 2002-03-08 Ravi Pratap <ravi@ximian.com>
3329 * attribute.cs (Attribute.UnmanagedType): This is to keep track of
3330 the unmanaged type in the case we have a MarshalAs attribute.
3332 (Resolve): Handle the case when we are parsing the special MarshalAs
3333 attribute [we need to store the unmanaged type to use later]
3335 * typemanager.cs (marshal_as_attr_type): Built in type for the
3336 MarshalAs Attribute.
3338 * attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute
3339 on parameters and accordingly set the marshalling info.
3341 2002-03-09 Miguel de Icaza <miguel@ximian.com>
3343 * class.cs: Optimizing slightly by removing redundant code after
3344 we switched to the `NoTypes' return value.
3345 (Property.DefineMethod): use NoTypes here too.
3347 This fixes the bug I introduced in my last batch of changes.
3349 2002-03-05 Ravi Pratap <ravi@ximian.com>
3351 * tree.cs (RecordEnum): Add. We now keep track of enums too.
3353 * class.cs (LookupInterfaceOrClass): Check against the list of recorded
3354 Enums since those are types too.
3356 * cs-parser.jay (enum_declaration): Record enums as we parse them.
3358 * enum.cs (DefineEnum): Return if the TypeBuilder has already been defined
3359 thanks to a call during the lookup process.
3361 2002-03-07 Miguel de Icaza <miguel@ximian.com>
3363 * statement.cs (Foreach): Lots of work to accomodate a particular
3364 kind of foreach statement that I had not kept in mind. It is
3365 possible to have foreachs on classes that provide a GetEnumerator
3366 method that return objects that implement the "pattern" for using
3367 a foreach, there is no need to support GetEnumerator
3370 This is needed to compile nant.
3372 * decl.cs: Only report 114 if the member is not `Finalize' and if
3373 the warning level is at least 2.
3375 * class.cs: Moved the compare function from Method to
3378 (MethodSignature.InheritableMemberSignatureCompare): Add new
3379 filter function that is used to extract inheritable methods from a
3382 (Method.Define): Use the new `inheritable_method_signature_filter'
3385 * cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
3388 2002-03-06 Miguel de Icaza <miguel@ximian.com>
3390 * ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
3392 * cs-parser.jay: Add opt_semicolon to the interface declaration.
3394 * expression.cs: Pass location information to
3395 ConvertImplicitStandard.
3397 * class.cs: Added debugging code to track return values from
3400 2002-03-05 Miguel de Icaza <miguel@ximian.com>
3402 * expression.cs (Is.DoResolve): If either side of the `is' is an
3403 interface, do not flag the warning.
3405 * ecore.cs (ImplicitReferenceConversion): We need a separate test
3408 * report.cs: Allow for --fatal to be used with --probe.
3410 * typemanager.cs (NoTypes): Move the definition for the empty Type
3413 * class.cs (TypeContainer.FindMembers): Also look for methods defined by
3415 (TypeContainer.DefineProxy): New function used to proxy to parent
3416 implementations when implementing interfaces.
3417 (TypeContainer.ParentImplements): used to lookup if our parent
3418 implements a public function that is required by an interface.
3419 (TypeContainer.VerifyPendingMethods): Hook this up.
3421 * typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
3422 `modules' and `assemblies' arraylists into arrays. We only grow
3423 these are the very early start up of the program, so this improves
3424 the speedof LookupType (nicely measured).
3426 * expression.cs (MakeByteBlob): Replaced unsafe code with
3427 BitConverter, as suggested by Paolo.
3429 * cfold.cs (ConstantFold.Binary): Special case: perform constant
3430 folding of string concatenation, but if either side is a string,
3431 and the other is not, then return null, and let the runtime use
3432 the concatenation on the string plus the object (using
3435 2002-03-04 Miguel de Icaza <miguel@ximian.com>
3437 Constant Folding has been implemented now.
3439 * expression.cs (Unary.Reduce): Do not throw an exception, catch
3440 the error instead on types that are not supported in one's
3443 * constant.cs (Constant and all children): New set of functions to
3444 perform implict and explicit conversions.
3446 * ecore.cs (EnumConstant): Implement the new functions to perform
3447 conversion by proxying to the child expression.
3449 * codegen.cs: (ConstantCheckState): Constant evaluation has its
3450 own separate setting that can not be turned off from the command
3451 line using --unchecked or --checked and is only controlled using
3452 the checked/unchecked statements and expressions. This setting is
3453 used by the constant folder to flag errors.
3455 * expression.cs (CheckedExpr, UncheckedExpr): Set the
3456 ConstantCheckState as well.
3458 During Resolve, they also have to flag the state, because the
3459 constant folder runs completely in the Resolve phase.
3461 * statement.cs (Checked, Unchecked): Set the ConstantCheckState as
3464 2002-03-01 Miguel de Icaza <miguel@ximian.com>
3466 * cfold.cs: New file, this file contains the constant folder.
3468 * ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
3469 argument to track whether we are using the resulting address to
3470 load or store a value and provide better error messages.
3472 (FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
3473 new AddressOf arguments.
3475 * statement.cs (Foreach.EmitCollectionForeach): Update
3477 * expression.cs (Argument.Emit): Call AddressOf with proper
3478 arguments to track usage.
3480 (New.DoEmit): Call AddressOf with new arguments.
3482 (Unary.Emit): Adjust AddressOf call.
3484 2002-03-01 Ravi Pratap <ravi@ximian.com>
3486 * cs-parser.jay (member_access): Change the case for pre-defined types
3487 to use a MemberAccess instead of a SimpleName. Thanks to Felix again for
3490 * class.cs (Operator::Emit): If we are abstract or extern, we don't have
3493 * attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
3494 essentially like methods and apply attributes like MethodImplOptions to them too.
3496 * ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
3499 * codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
3500 DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
3503 * Update code everywhere accordingly.
3505 * ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
3507 * cs-parser.jay (enum_declaration): Set the current namespace of the enum.
3509 2002-02-28 Ravi Pratap <ravi@ximian.com>
3511 * rootcontext.cs (LookupType): As we cycle through the chain of namespaces
3512 try performing lookups against those instead of jumping straight into using
3513 the 'using' clauses.
3515 (ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
3517 (LookupType): Perform lookups in implicit parents too.
3519 * class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
3520 sequence as RootContext.LookupType.
3522 * rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries
3523 the various cases of namespace lookups into this method.
3525 2002-03-01 Miguel de Icaza <miguel@ximian.com>
3527 * cs-parser.jay: Add support for [Attribute ()] (empty arguments
3528 in positional arguments)
3530 * class.cs (Operator): Update the AllowedModifiers to contain
3533 * cs-parser.jay: Update operator declaration to allow for the
3534 operator body to be empty.
3536 * cs-tokenizer.cs: Added '\u' unicode support in strings and hex
3539 2002-02-27 Miguel de Icaza <miguel@ximian.com>
3541 * class.cs (Method.Emit): Label parameters.
3543 * driver.cs: Return 1 or 0 as the program exit code.
3545 2002-02-26 Miguel de Icaza <miguel@ximian.com>
3547 * expression.cs: Special case the `null' object when trying to
3548 auto-compute the type, as anything can be explicitly converted to
3551 * ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
3552 spotting this Paolo.
3554 (Expression.ImplicitNumericConversion): Perform comparissions of
3555 the type using the underlying type in the case of an enumeration
3556 rather than using the enumeration type for the compare.
3558 Cope with the underlying == type case, which is not possible to
3561 (Expression.ConvertNumericExplicit): Perform comparissions of
3562 the type using the underlying type in the case of an enumeration
3563 rather than using the enumeration type for the compare.
3565 * driver.cs: If the user does not supply an extension, assume .exe
3567 * cs-parser.jay (if_statement): Rewrote so that we can track the
3568 location for the if statement.
3570 * expression.cs (Binary.ConstantFold): Only concat strings when
3571 the operation is "+", not everything ;-)
3573 * statement.cs (Statement.EmitBoolExpression): Take a location
3575 (If, While, Do): Track location.
3577 * expression.cs (Binary.ResolveOperator): In the object + string
3578 case, I was missing a call to ConvertImplicit
3580 2002-02-25 Ravi Pratap <ravi@ximian.com>
3582 * parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
3583 Location arguments. Ensure we use RootContext.LookupType to do our work
3584 and not try to do a direct Type.GetType and ModuleBuilder.GetType
3586 * interface.cs (PopulateMethod): Handle the type of the parameter being
3589 * expression.cs (Invocation.BetterFunction): Handle the case when we
3590 have a params method with no fixed arguments and a call is made with no
3593 2002-02-25 Miguel de Icaza <miguel@ximian.com>
3595 * cs-tokenizer.cs: Add support for the quote-escape-sequence in
3596 the verbatim-string-literal
3598 * support.cs (InternalParameters.ParameterModifier): handle null
3600 (InternalParameters.ParameterType): ditto.
3602 * parameter.cs (VerifyArgs): Also check if the fixed parameter is
3603 duplicating the name of the variable parameter.
3604 (GetParameterByName): Fix bug where we were not looking up array
3605 paramters if they were the only present (thanks Paolo!).
3606 (GetParameterInfo): We only have an empty set of types if both
3607 fixed and array are set to null.
3608 (GetParameterInfo-idx): Handle FixedParameter == null
3610 * cs-parser.jay: Handle the case where there is no catch
3611 statements (missing null test).
3613 2002-02-22 Miguel de Icaza <miguel@ximian.com>
3615 * driver.cs (MainDriver): Be conservative on our command line
3618 Catch DirectoryNotFoundException when calling GetFiles.
3620 (SplitPathAndPattern): Used to split the input specification into
3621 a path and a pattern that we can feed to Directory.GetFiles.
3623 2002-02-21 Miguel de Icaza <miguel@ximian.com>
3625 * statement.cs (Fixed): Implement the last case of the Fixed
3626 statement (string handling).
3628 * expression.cs (StringPtr): New class used to return a char * to
3629 a string; Used by the Fixed statement.
3631 * typemanager.cs: Add char_ptr_type. Add get_OffsetToStringData method.
3633 * expression.cs (Binary.ResolveOperator): Remove redundant
3634 MemberLookup pn parent type.
3635 Optimize union call, we do not need a union if the types are the same.
3636 (Unary.ResolveOperator): REmove redundant MemberLookup on parent
3639 Specialize the use of MemberLookup everywhere, instead of using
3640 the default settings.
3642 (StackAlloc): Implement stackalloc keyword.
3644 * cs-parser.jay: Add rule to parse stackalloc.
3646 * driver.cs: Handle /h, /help, /?

3653 2002-02-20 Miguel de Icaza <miguel@ximian.com>
3655 * expression.cs (PointerArithmetic): New class that is used to
3656 perform pointer arithmetic.
3657 (Binary.Resolve): Handle pointer arithmetic
3658 Handle pointer comparission.
3659 (ArrayPtr): Utility expression class that is used to take the
3660 address of an array.
3662 (ElementAccess): Implement array access for pointers
3664 * statement.cs (Fixed): Implement fixed statement for arrays, we
3665 are missing one more case before we are done.
3667 * expression.cs (Indirection): Implement EmitAssign and set the
3668 ExprClass to Variable. This allows pointer dereferences to be
3669 treated as variables, and to have values assigned to them.
3671 * ecore.cs (Expression.StoreFromPtr): New utility function to
3672 store values dereferencing.
3674 2002-02-20 Ravi Pratap <ravi@ximian.com>
3676 * expression.cs (Binary.ResolveOperator): Ensure that we are
3677 not trying to operate on a void type - this fixes the reported
3680 * decl.cs (CheckMethodAgainstBase): Do not allow overriding if
3681 the parent implementation is sealed.
3683 * ../errors/cs0239.cs : Add.
3685 * attribute.cs (ApplyAttributes): Handle Modulebuilders too.
3687 * typemanager.cs (unverifiable_code_type): Corresponds to
3688 System.Security.UnverifiableCodeAttribute. We need to emit this for modules
3689 which have unsafe code in them.
3691 * rootcontext.cs (EmitCode): Emit the above attribute when we are in an
3694 2002-02-19 Miguel de Icaza <miguel@ximian.com>
3696 * cs-tokenizer.cs: Add support for @"litreal strings"

3710 * expression.cs (Indirection): New helper class. Unary will
3711 create Indirection classes to be able to implement the
3712 IMemoryLocation interface on it.
3714 2002-02-16 Miguel de Icaza <miguel@ximian.com>
3716 * cs-parser.jay (fixed_statement): reference the right statement.

3719 statement for the &x case.
3721 2002-02-14 Miguel de Icaza <miguel@ximian.com>
3723 * class.cs (Property.Define, Method.Define): Remove newslot when
3726 * modifiers.cs: My use of NewSlot when `Abstract' was set was
3727 wrong. NewSlot should only be used if the `new' keyword is present.
3729 * driver.cs (GetSystemDir): Use CodeBase instead of FullName for
3730 locating our system dir. Sorry about this.
3732 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3734 * driver.cs (GetSystemDir): Compute correctly the location of our
3735 system assemblies. I was using the compiler directory instead of
3736 the library directory.
3738 2002-02-13 Ravi Pratap <ravi@ximian.com>
3740 * expression.cs (BetterFunction): Put back in what Miguel commented out
3741 since it is the correct fix. The problem is elsewhere ;-)
3743 (IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
3744 parameters of the parms method are themselves compatible or not !
3746 (StandardConversionExists): Fix very dangerous bug where we were forgetting
3747 to check that a class implements an interface before saying that an implicit
3748 conversion was allowed. Use ImplementsInterface to do the checking.
3750 2002-02-13 Miguel de Icaza <miguel@ximian.com>
3752 * class.cs (Method.Define): Track whether we are an explicit
3753 implementation or not. And only call DefineMethodOverride if we
3754 are an explicit implementation.
3756 (Property.DefineMethod): Ditto.
3758 2002-02-11 Ravi Pratap <ravi@ximian.com>
3760 * expression.cs (BetterFunction): Catch hideous bug which was
3761 preventing us from detecting ambiguous calls due to implicit casts i.e
3764 2002-01-29 Miguel de Icaza <miguel@ximian.com>
3766 * support.cs (Pair): Remove un-needed method. I figured why I was
3767 getting the error in cs-parser.jay, the variable in a foreach loop
3768 is readonly, and the compiler does not really treat this as a variable.
3770 * cs-parser.jay (fixed_statement): Fix grammar. Use ASSIGN
3771 instead of EQUALS in grammar.
3773 * typemanager.cs (VerifyUnmanaged): Report correct error (208)
3775 * expression.cs (Unary.DoResolve): Check whether the argument is
3778 2002-01-28 Miguel de Icaza <miguel@ximian.com>
3780 * support.cs: Api for Pair to set a value. Despite the fact that
3781 the variables are public the MS C# compiler refuses to compile
3782 code that accesses the field if the variable is part of a foreach
3785 * statement.cs (Fixed): Begin implementation of the fixed
3788 (Block.AddVariable): Return the VariableInfo on success and null
3789 on failure instead of true/false.
3791 * cs-parser.jay (foreach): Catch errors on variables already
3792 defined (we were ignoring this value before) and properly unwind
3795 (fixed_statement): grammar for the fixed statement.
3797 2002-01-25 Miguel de Icaza <miguel@ximian.com>
3799 * expression.cs (UnaryMutator.IsIncrementableNumber): Allow also
3800 pointer types to be incretemented.

3813 * ecore.cs (Expression.UnsafeError): Reports error 214 (pointer
3814 use in non-unsafe context).
3816 (SimpleName.DoResolve): Check for pointers in field access on safe
3819 (Expression.LoadFromPtr): Factor the load-indirect code in this
3820 function. This was duplicated in UnboxCast and ParameterReference
3822 2002-01-24 Miguel de Icaza <miguel@ximian.com>
3824 * expression.cs (ComposedCast): report an error if a pointer cast
3825 is used in a safe region.
3827 * ecore.cs (Expression.ConvertExplicit): Add rules for implicit
3828 pointer type casts in unsafe context.
3830 * codegen.cs (EmitContext): Set up IsUnsafe.
3832 * cs-parser.jay (non_expression_type): Add productions for pointer
3835 * expression.cs (Invocation.EmitCall): Remove chunk of buggy
3836 code. We should not use force into static mode if the method is
3837 not virtual. Fixes bug in MIS
3839 * statement.cs (Do.Emit, While.Emit, For.Emit,
3840 Statement.EmitBoolExpression): Add support to Do and While to
3841 propagate infinite loop as `I do return' semantics.
3843 Improve the For case to also test for boolean constants.
3845 * attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
3846 to the list of attributes we can add.
3848 Remove `EmitContext' argument.
3850 * class.cs (Method.Define): Apply parameter attributes.
3851 (Constructor.Define): Apply parameter attributes.
3852 (MethodCore.LabelParameters): Move here the core of labeling
3855 * support.cs (ReflectionParameters.ParameterModifier,
3856 InternalParameters.ParameterModifier): Use IsByRef on the type and
3857 only return the OUT bit for these parameters instead of in/out/ref
3860 This is because I miss-understood things. The ParameterInfo.IsIn
3861 and IsOut represent whether the parameter has the [In] and [Out]
3864 2002-01-22 Miguel de Icaza <miguel@ximian.com>
3866 * ecore.cs (FieldExpr.Emit): Release temporaries.
3868 * assign.cs (LocalTemporary.Release): new function.
3870 * codegen.cs (EmitContext.GetTemporaryStorage,
3871 EmitContext.FreeTemporaryStorage): Rework the way we deal with
3872 temporary storage. Now we can "put back" localbuilders when we
3875 2002-01-21 Miguel de Icaza <miguel@ximian.com>
3877 * ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
3878 need to make a copy of the variable to generate verifiable code.
3880 2002-01-19 Miguel de Icaza <miguel@ximian.com>
3882 * driver.cs: Compute dynamically the system directory.
3884 * ecore.cs (CopyNewMethods): reworked, exposed, made public.
3885 Slower, but more generally useful. Used by the abstract
3886 registering implementation.
3888 * expression.cs (ResolveMemberAccess): Reorder the way we evaluate
3889 the rules for the special rule on Type/instances. First check if
3890 we have the same name, and if so, try that special static path
3891 rather than the instance path.
3893 2002-01-18 Miguel de Icaza <miguel@ximian.com>
3895 * cs-parser.jay: Emit 642 (warning: possible empty statement) for
3898 * class.cs (TypeBuilder.DefineType): Do not allow inheritance from
3899 Enum, ValueType, Delegate or Array for non-corlib compiles.
3901 * cs-tokenizer.cs: Catch long identifiers (645)
3903 * typemanager.cs (IndexerPropetyName): Ravi never tested this
3906 * class.cs (TypeContainer.RegisterRequiredImplementations): Bug
3907 fix, we were returning too early, so we were not registering
3908 pending methods from abstract classes.
3910 Do not register pending methods if the class is abstract.
3912 * expression.cs (Conditional.DoResolve): Report circular implicit
3913 conversions when we neecd to compute it for conditional
3916 (Is.DoResolve): If the expression is always of the provided type,
3917 flag warning 183. If the expression can not ever be of the
3918 provided type flag warning 184.
3920 * class.cs: Catch 169 as well.
3922 * ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
3925 2002-01-18 Nick Drochak <ndrochak@gol.com>
3927 * makefile: remove path to beta2 csc.exe. path to csc.exe must be in PATH instead.
3929 2002-01-17 Miguel de Icaza <miguel@ximian.com>
3931 * interface.cs: (PopulateMethod): Check for pointers being defined
3932 only if the unsafe context is active.
3933 (PopulateProperty): ditto.
3934 (PopulateIndexer): ditto.
3936 * class.cs (Method, Method.Define): Allow `unsafe' modifier to be
3937 specified. If pointers are present, make sure that they are
3938 present in an unsafe context.
3939 (Constructor, Constructor.Define): ditto.
3940 (Field, Field.Define): ditto.
3941 (Property, Property.Define): ditto.
3942 (Event, Event.Define): ditto.
3944 * interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
3945 hashtable if there are classes or structs defined.
3947 * expression.cs (LocalVariableReference.DoResolve): Simplify this
3948 code, as the constant resolution moved.
3950 * statement.cs (Block.EmitMeta): Resolve all constants as we emit
3951 the metadata, so we can flag error 133.
3953 * decl.cs (MemberCore.UnsafeOK): New function to test that a
3954 pointer is being declared in an unsafe context.
3956 2002-01-16 Miguel de Icaza <miguel@ximian.com>
3958 * modifiers.cs (Modifiers.Check): Require a Location argument.
3959 Report error 227 for Unsafe use.
3961 * typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
3963 * statement.cs (For.Emit): If the test is null, then report that
3964 we do `return', as we wont reach anything afterwards.
3966 (Switch.SwitchGoverningType): Track the expression that matched
3969 * driver.cs: Allow negative numbers as an error code to flag.
3971 * cs-parser.jay: Handle 1551.
3973 * namespace.cs: Add 1537 checking (repeated using alias namespaces).
3975 2002-01-15 Miguel de Icaza <miguel@ximian.com>
3977 * cs-parser.jay: Report 1518 (type declaration can only contain
3978 class, struct, interface, enum or delegate)
3980 (switch_label): Report 1523 (keywords `case' or `default' must
3983 (opt_switch_sections): Report 1522 (empty switch)
3985 * driver.cs: Report 1515 (response file specified multiple times)
3986 Report 1516 (Source file specified multiple times).
3988 * expression.cs (Argument.Resolve): Signal 1510
3990 (BaseAccess.Resolve, BaseIndexer.Resolve): Signal 1511 (base
3991 access not allowed in static code)
3993 2002-01-11 Ravi Pratap <ravi@ximian.com>
3995 * typemanager.cs (IsPointerType): Utility method which we are going
3998 * ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
3999 the object type, so we take care of that.
4001 * expression.cs (FullMethodDesc): Also include the return type in descriptions.
4003 * support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
4004 added to non-params parameters :-)
4006 * typemanager.cs (CSharpName): Include 'void' type too.
4008 (void_ptr_type): Include in the set of core types.
4010 * ecore.cs (ConvertImplicit): Make use of ConvertImplicitStandard instead of
4013 (ConvertImplicitStandard): Handle standard implicit pointer conversions when we have
4016 * cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had
4017 completely forgotten about it.
4019 2002-01-10 Ravi Pratap <ravi@ximian.com>
4021 * cs-parser.jay (pointer_type): Add. This begins our implementation
4022 of parsing rules for unsafe code.
4024 (unsafe_statement): Implement.
4026 (embedded_statement): Modify to include the above.
4028 * statement.cs (Unsafe): Implement new class for unsafe blocks.
4030 * codegen.cs (EmitContext.InUnsafe): Add. This determines
4031 if the current context is an unsafe one.
4033 * cs-parser.jay (local_variable_pointer_type): Since local variable types
4034 are handled differently, we need separate rules for them.
4036 (local_variable_declaration): Update to use local_variable_pointer_type
4037 to allow variable declarations of unmanaged pointer types.
4039 * expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
4042 * ../errors/cs0214.cs : Add.
4044 2002-01-16 Nick Drochak <ndrochak@gol.com>
4046 * makefile: remove 'response' file when cleaning.
4048 2002-01-15 Miguel de Icaza <miguel@ximian.com>
4050 * cs-parser.jay: Report 1524.
4052 2002-01-14 Miguel de Icaza <miguel@ximian.com>
4054 * typemanager.cs (RegisterMethod): drop checking if we have
4055 registered this from here
4057 2002-01-12 Miguel de Icaza <miguel@ximian.com>
4059 * class.cs (Method.EmitDestructor): Implement calling our base
4062 * statement.cs (Try.Emit): Fix to reset the InFinally to the old
4065 * codegen.cs (EmitContext.EmitTopBlock): Destructors will call
4066 this routine and will wrap the call in a try/catch block. Deal
4069 2002-01-11 Miguel de Icaza <miguel@ximian.com>
4071 * ecore.cs (Expression.MemberLookup): instead of taking a
4072 parameter `same_type' that was used to tell whether we could
4073 access private members we compute our containing type from the
4076 (FieldExpr): Added partial support for volatile fields. This does
4077 not work for volatile fields exposed from assemblies, as I can not
4078 figure out how to extract the modreq from it.
4080 Updated all the source files to use this.
4082 * codegen.cs (EmitContext): Compute ContainerType ahead of time,
4083 because it is referenced by MemberLookup very often.
4085 2002-01-09 Ravi Pratap <ravi@ximian.com>
4087 * typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
4088 TypeBuilder.GetCustomAttributes to retrieve what we need.
4090 Get rid of redundant default_member_attr_type as this is the same as
4091 default_member_type which already exists.
4093 * interface.cs, attribute.cs : Update accordingly.
4095 2002-01-08 Miguel de Icaza <miguel@ximian.com>
4097 * typemanager.cs: Enable IndexerPropertyName again. It does not
4098 work for TYpeBuilders though. Ravi, can you please fix this?
4100 * cs-tokenizer.cs: Accept _ as a name in pp-expressions.
4102 * expression.cs (Argument.Emit): Handle the case of ref objects
4103 being passed to ref functions;
4105 (ParameterReference.EmitLoad): Loads the content of the pointer
4106 without dereferencing.
4108 2002-01-07 Miguel de Icaza <miguel@ximian.com>
4110 * cs-tokenizer.cs: Implemented the pre-processing expressions.
4112 2002-01-08 Ravi Pratap <ravi@ximian.com>
4114 * class.cs (Indexer.DefineMethod): Incorporate the interface
4115 type in the name of the method if we are doing explicit interface
4118 * expression.cs (ConversionExists): Remove as it is completely obsolete.
4120 (BetterConversion): Fix extremely trivial bug where we were referring to
4121 ConversionExists instead of StandardConversionExists ! Hooray, things are fine
4124 * ../errors/bug16.cs : Add although we have fixed it.
4126 2002-01-07 Miguel de Icaza <miguel@ximian.com>
4128 * expression.cs (BaseIndexer): Begin implementation.
4130 * class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
4132 * cs-parser.jay (indexer_declarator): Use qualified_identifier
4133 production directly to remove a shift/reduce, and implement
4134 explicit interface implementation.
4136 * cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
4137 after a floating point suffix.
4139 * expression.cs (DoNumericPromotions): Improved the conversion for
4140 uint/uint. If we have a constant, we avoid doing a typecast to a
4143 * class.cs (Indexer): Implement explicit interface implementation
4146 Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
4148 * class.cs: make the default instance constructor public and hidebysig.
4150 2001-01-03 Ravi Pratap <ravi@ximian.com>
4152 * interface.cs (EmitDefaultMemberAttr): Make this helper method static
4153 so we can call it from elsewhere.
4155 * class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
4156 we emit it internally if the class has a defined indexer; otherwise the user
4157 emits it by decorating the class definition with the DefaultMemberAttribute.
4159 * attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
4160 attribute is not used on a type which defines an indexer.
4162 * cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
4163 character when we skip whitespace.
4165 * ../errors/cs0646.cs : Add.
4167 2002-01-03 Miguel de Icaza <miguel@ximian.com>
4169 * ecore.cs (SimpleName.ResolveSimpleName): Report error 120
4172 * makefile: Add practical target `mcs3.exe' which builds the third
4173 generation compiler.
4175 * expression.cs (New): Fix structures constructor calling.
4177 * class.cs (Property, Method, Indexer): Emit Final flag on the
4178 method if we are an interface implementation and we are not
4181 * ecore.cs (PropertyExpr): New public field `IsBase', tells
4182 whether this property is referencing a `base' method.
4184 * expression.cs (Invocation.EmitCall): take an extra argument:
4185 is_base, this is used to determine whether the `call' or
4186 `callvirt' opcode should be used.
4189 * delegate.cs: update EmitCall.
4191 * class.cs (Method.Define): Set NewSlot for the cases where we are
4192 not implementing an interface method.
4194 (Property.Define): ditto.
4196 2002-01-02 Miguel de Icaza <miguel@ximian.com>
4198 * cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
4199 'r'. Allows mcs to parse itself fully.
4201 2002-01-02 Ravi Pratap <ravi@ximian.com>
4203 * expression.cs (ArrayCreation.num_automatic_initializers): Keep track
4204 of the number of initializers that require the InitializeArray method.
4206 (CheckIndices): Store the Expression in all cases - not the plain value. Also
4207 update the above field where necessary.
4209 (MakeByteBlob): Update accordingly.
4211 (DoEmit): Call EmitStaticInitializers only if the number of initializers is
4214 (EmitDynamicInitializers): Update in accordance with the new optimization.
4216 (ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
4217 same OpCode applies.
4219 * cs-parser.jay : Fix some glaring errors I introduced.
4221 2002-01-01 Ravi Pratap <ravi@ximian.com>
4223 * parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
4224 so that we can check for name clashes there too.
4226 * typemanager.cs (default_member_attr_type): The attribute that we need to emit
4227 for interface indexers.
4229 * interfaces.cs (Define): Emit the default member attribute.
4231 * expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
4232 variable was being referred to while setting the value ;-)
4234 2002-01-01 Miguel de Icaza <miguel@ximian.com>
4236 * expression.cs (MakeByteBlob): Optimize: we do not need to fill
4237 byte-by-byte information when we know the data is zero.
4239 Make the block always a multiple of 4, because
4240 DefineInitializedData has a bug.
4242 * assign.cs: Fix, we should assign from the temporary, not from
4245 * expression.cs (MakeByteBlob): Fix my incorrect code.
4247 2001-12-31 Miguel de Icaza <miguel@ximian.com>
4249 * typemanager.cs (EnumToUnderlying): This function is used to get
4250 the underlying type from an enumeration, because it does not
4253 * constant.cs: Use the I4_S form for values between -128 and 127.
4255 * statement.cs (Block.LookupLabel): Looks up a label.
4256 (Block): Drop support for labeled blocks.
4258 (LabeledStatement): New kind of statement that represents a label
4261 (Goto): Finally implement this bad boy.
4263 * cs-parser.jay: Update to reflect new mechanism to implement
4266 2001-12-30 Miguel de Icaza <miguel@ximian.com>
4268 * codegen.cs (EmitContext.This): a codegen property that keeps the
4269 a single instance of this instead of creating many different this
4272 * delegate.cs (Delegate.DoResolve): Update to use the property;
4274 * ecore.cs (SimpleName.SimpleNameResolve): Ditto
4276 * expression.cs (BaseAccess.DoResolve): Ditto.
4278 2001-12-29 Ravi Pratap <ravi@ximian.com>
4280 * typemanager.cs (methodimpl_attr_type): Add to hold the type
4281 corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
4283 (InitCoreTypes): Update accordingly.
4285 * attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
4286 so we can quickly store the state.
4288 (ApplyAttributes): Set the correct implementation flags
4289 for InternalCall methods.
4291 2001-12-29 Miguel de Icaza <miguel@ximian.com>
4293 * expression.cs (EmitCall): if a method is not virtual, then do
4294 not use callvirt on it.
4296 (ArrayAccess.EmitAssign): storing non-builtin value types (ie,
4297 user defined stuff) requires the use of stobj, which takes an
4298 address on the stack instead of an array and an index. So emit
4299 the Ldelema operation for it.
4301 (EmitStoreOpcode): Use stobj for valuetypes.
4303 (UnaryMutator.EmitCode): Use the right 1 value depending on
4304 whether we are dealing with int64/uint64, float or doubles.
4306 * class.cs (TypeContainer.AddConstructor): Fix the logic to define
4307 constructors that I implemented last night.
4309 (Constructor.IsDefault): Fix to work properly for static
4312 * cs-parser.jay (CheckDef): report method signature errors.
4313 Update error number 103 to be 132.
4315 * decl.cs: New AdditionResult enumeration value: MethodExists.
4316 Although we do this check for methods later on in the semantic
4317 analysis, catching repeated default constructors is so easy that
4318 we catch these here.
4320 * expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
4323 (ParameterReference.EmitAssign, Emit): handle
4326 (ArrayAccess.EmitLoadOpcode): Handle bool type here.
4327 (ArrayAccess.EmitStoreOpcode): ditto.
4329 * cs-tokenizer.cs (is_punct): Eliminated empty computation.
4331 * expression.cs (MakeByteBlob): Complete all the missing types
4332 (uint, short, ushort, byte, sbyte)
4334 * class.cs: Only init instance field initializers on instance
4337 Rename `constructors' to instance_constructors.
4339 (TypeContainer.AddConstructor): Only add constructors to the list
4340 if it is not static.
4342 Make sure that we handle default_static_constructor independently
4343 everywhere where we handle instance_constructors
4345 2001-12-28 Miguel de Icaza <miguel@ximian.com>
4347 * class.cs: Do not lookup or create a base initializer for a
4350 (ConstructorInitializer.Resolve): use the proper type to lookup
4353 * cs-parser.jay: Report error 1585 (modifiers between type and name).
4355 * enum.cs, interface.cs: Remove CloseType, this is taken care by
4358 * decl.cs: CloseType is now an virtual method, the default
4359 implementation just closes this type.
4361 2001-12-28 Ravi Pratap <ravi@ximian.com>
4363 * attribute.cs (DefinePInvokeMethod): Set the implementation flags
4364 to PreserveSig by default. Also emit HideBySig on such methods.
4366 Basically, set the defaults to standard values.
4368 * expression.cs (Invocation.BetterFunction): We need to make sure that for each
4369 argument, if candidate is better, it can't be worse than the best !
4371 (Invocation): Re-write bits to differentiate between methods being
4372 applicable in their expanded form and their normal form - for params
4375 Get rid of use_standard everywhere as only standard conversions are allowed
4376 in overload resolution.
4378 More spec conformance.
4380 2001-12-27 Miguel de Icaza <miguel@ximian.com>
4382 * driver.cs: Add --timestamp, to see where the compiler spends
4385 * ecore.cs (SimpleName.DoResolve): Do not create an implicit
4386 `this' in static code.
4388 (SimpleName.DoResolve): Implement in terms of a helper function
4389 that allows static-references to be passed upstream to
4392 (Expression.ResolveWithSimpleName): Resolve specially simple
4393 names when called by MemberAccess to implement the special
4396 (Expression.ImplicitReferenceConversion): Handle conversions from
4397 Null to reference types before others, as Null's type is
4400 * expression.cs (Invocation.EmitCall): Handle the special case of
4401 calling methods declared on a reference type from a ValueType
4402 (Base classes System.Object and System.Enum)
4404 (MemberAccess.Resolve): Only perform lookups on Enumerations if
4405 the left hand side is a TypeExpr, not on every enumeration.
4407 (Binary.Resolve): If types are reference types, then do a cast to
4408 object on operators != and == of both arguments.
4410 * typemanager.cs (FindMembers): Extract instance and static
4411 members if requested.
4413 * interface.cs (PopulateProperty): Use void_type instead of null
4414 as the return type for the setter method.
4416 (PopulateIndexer): ditto.
4418 2001-12-27 Ravi Pratap <ravi@ximian.com>
4420 * support.cs (ReflectionParameters): Fix minor bug where we
4421 were examining the wrong parameter for the ParamArray attribute.
4423 Cope with requests for the type of the parameter at position
4424 greater than the params parameter's. We now return the element
4425 type of the params array as that makes more sense.
4427 * expression.cs (Invocation.IsParamsMethodApplicable): Update
4428 accordingly as we no longer have to extract the element type
4431 (Invocation.OverloadResolve): Update.
4433 2001-12-27 Miguel de Icaza <miguel@ximian.com>
4435 * statement.cs (Foreach.GetEnumeratorFilter): Do not compare
4436 against IEnumerator, test whether the return value is a descendant
4437 of the IEnumerator interface.
4439 * class.cs (Indexer.Define): Use an auxiliary method to implement
4440 the other bits of the method definition. Begin support for
4441 explicit interface implementation.
4443 (Property.DefineMethod): Use TypeManager.void_type instead of null
4444 for an empty return value.
4446 2001-12-26 Miguel de Icaza <miguel@ximian.com>
4448 * expression.cs (MemberAccess.ResolveMemberAccess): if we are
4449 dealing with a FieldExpr which is composed of a FieldBuilder, in
4450 the code path we did extract the constant, but we should have
4451 obtained the underlying value to be able to cast it (otherwise we
4452 end up in an infinite loop, this is what Ravi was running into).
4454 (ArrayCreation.UpdateIndices): Arrays might be empty.
4456 (MemberAccess.ResolveMemberAccess): Add support for section
4457 14.5.4.1 that deals with the special case of E.I when E is a type
4458 and something else, that I can be a reference to a static member.
4460 (ArrayCreation.MakeByteBlob): It is not an error to not be able to
4461 handle a particular array type to create byte blobs, it is just
4462 something we dont generate byteblobs for.
4464 * cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
4467 * location.cs (Push): remove the key from the hashtable that we
4468 are about to add. This happens for empty files.
4470 * driver.cs: Dispose files after we have parsed them.
4472 (tokenize): new function that only runs the tokenizer on its
4473 input, for speed testing.
4475 2001-12-26 Ravi Pratap <ravi@ximian.com>
4477 * class.cs (Event.Define): Define the private field only if there
4478 are no accessors defined.
4480 * expression.cs (ResolveMemberAccess): If there is no associated
4481 field with the event, that means we have an event defined with its
4482 own accessors and we should flag error cs0070 since transforming
4483 ourselves into a field is not valid in that case.
4485 * ecore.cs (SimpleName.DoResolve): Same as above.
4487 * attribute.cs (DefinePInvokeMethod): Set the default calling convention
4488 and charset to sane values.
4490 2001-12-25 Ravi Pratap <ravi@ximian.com>
4492 * assign.cs (DoResolve): Perform check on events only if they
4493 are being accessed outside the declaring type.
4495 * cs-parser.jay (event_declarations): Update rules to correctly
4496 set the type of the implicit parameter etc.
4498 (add_accessor, remove_accessor): Set current local parameters.
4500 * expression.cs (Binary): For delegate addition and subtraction,
4501 cast the return value from the method into the appropriate delegate
4504 2001-12-24 Ravi Pratap <ravi@ximian.com>
4506 * typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
4507 of these as the workaround is unnecessary.
4509 * delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
4510 delegate data - none of that is needed at all.
4512 Re-write bits to extract the instance expression and the delegate method
4515 * expression.cs (Binary.ResolveOperator): Handle the '-' binary operator
4518 * attribute.cs (ApplyAttributes): New method to take care of common tasks
4519 of attaching attributes instead of duplicating code everywhere.
4521 * everywhere : Update code to do attribute emission using the above method.
4523 2001-12-23 Miguel de Icaza <miguel@ximian.com>
4525 * expression.cs (IsParamsMethodApplicable): if there are not
4526 parameters, return immediately.
4528 * ecore.cs: The 0 literal can be implicity converted to an enum
4531 (SimpleName.DoResolve): First lookup the type, then lookup the
4534 (FieldExpr.Emit): If the InstanceExpression is a ValueType, we
4535 want to get its address. If the InstanceExpression is not
4536 addressable, store the result in a temporary variable, then get
4539 * codegen.cs: Only display 219 errors on warning level or above.
4541 * expression.cs (ArrayAccess): Make it implement the
4542 IMemoryLocation interface.
4544 (Binary.DoResolve): handle the operator == (object a, object b)
4545 and operator != (object a, object b) without incurring into a
4546 BoxedCast (because 5 != o should never be performed).
4548 Handle binary enumerator operators.
4550 (EmitLoadOpcode): Use Ldelema if the object we are loading is a
4551 value type, otherwise use Ldelem_ref.
4553 Use precomputed names;
4555 (AddressOf): Implement address of
4557 * cs-parser.jay (labeled_statement): Fix recursive block
4558 addition by reworking the production.
4560 * expression.cs (New.DoEmit): New has a special case:
4562 If we are dealing with a ValueType, we have a few
4563 situations to deal with:
4565 * The target of New is a ValueType variable, that is
4566 easy, we just pass this as the variable reference
4568 * The target of New is being passed as an argument,
4569 to a boxing operation or a function that takes a
4572 In this case, we need to create a temporary variable
4573 that is the argument of New.
4576 2001-12-23 Ravi Pratap <ravi@ximian.com>
4578 * rootcontext.cs (LookupType): Check that current_type is not null before
4579 going about looking at nested types.
4581 * ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
4582 not implement the IAssignMethod interface any more.
4584 * expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
4585 where we tranform them into FieldExprs if they are being resolved from within
4588 * ecore.cs (SimpleName.DoResolve): Do the same here.
4590 * assign.cs (DoResolve, Emit): Clean up code considerably.
4592 * ../errors/bug10.cs : Add.
4594 * ../errors/cs0070.cs : Add.
4596 * typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.
4598 * assign.cs : Get rid of EventIsLocal everywhere.
4600 2001-12-23 Miguel de Icaza <miguel@ximian.com>
4602 * ecore.cs (ConvertIntLiteral): finished the implementation.
4604 * statement.cs (SwitchLabel): Convert the value we are using as a
4605 key before looking up the table.
4607 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4609 * codegen.cs (EmitTopBlock): Require a Location argument now.
4611 * cs-parser.jay (constructor_declarator): We need to setup
4612 current_local_parameters before we parse the
4613 opt_constructor_initializer, to allow the variables to be bound
4614 to the constructor arguments.
4616 * rootcontext.cs (LookupType): First lookup nested classes in our
4617 class and our parents before we go looking outside our class.
4619 * expression.cs (ConstantFold): Extract/debox the values at the
4622 * rootcontext.cs (EmitCode): Resolve the constants first before we
4623 resolve the types. This is not really needed, but it helps debugging.
4625 * statement.cs: report location.
4627 * cs-parser.jay: pass location to throw statement.
4629 * driver.cs: Small bug fix.
4631 * report.cs: Updated format to be 4-zero filled digits.
4633 2001-12-22 Ravi Pratap <ravi@ximian.com>
4635 * expression.cs (CheckIndices): Fix minor bug where the wrong
4636 variable was being referred to ;-)
4638 (DoEmit): Do not call EmitStaticInitializers when the
4639 underlying type is System.Object.
4641 2001-12-21 Ravi Pratap <ravi@ximian.com>
4643 * ecore.cs (EventExpr.Resolve): Implement to correctly set the type
4644 and do the usual workaround for SRE.
4646 * class.cs (MyEventBuilder.EventType): New member to get at the type
4647 of the event, quickly.
4649 * expression.cs (Binary.ResolveOperator): Handle delegate addition.
4651 * assign.cs (Assign.DoResolve): Handle the case when the target
4652 is an EventExpr and perform the necessary checks.
4654 * ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
4657 (SimpleName.MemberStaticCheck): Include check for EventExpr.
4659 (EventExpr): Set the type in the constructor itself since we
4660 are meant to be born fully resolved.
4662 (EventExpr.Define): Revert code I wrote earlier.
4664 * delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
4665 instance expression is null. The instance expression is a This in that case
4666 or a null, depending on whether it is a static method or not.
4668 Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
4669 refers to more than one method.
4671 * assign.cs (DoResolve): Check whether the event belongs to the same Type container
4672 and accordingly flag errors.
4674 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4676 * statement.cs (Throw.Emit): Add support for re-throwing exceptions.
4678 2001-12-22 Miguel de Icaza <miguel@ximian.com>
4680 * location.cs (ToString): Provide useful rutine.
4682 2001-12-21 Miguel de Icaza <miguel@ximian.com>
4684 * ecore.cs (Expression.ConvertIntLiteral): Do not return Constant
4685 objects, return the actual integral boxed.
4687 * statement.cs (SwitchLabel): define an ILLabel for each
4690 (Switch.CheckSwitch): If the value is a Literal, extract
4691 the underlying literal.
4693 Also in the unused hashtable we had, add the SwitchLabel so we can
4694 quickly look this value up.
4696 * constant.cs: Implement a bunch of new constants. Rewrite
4697 Literal based on this. Made changes everywhere to adapt to this.
4699 * expression.cs (Expression.MakeByteBlob): Optimize routine by
4700 dereferencing array only once, and also copes with enumrations.
4702 bytes are two bytes wide, not one.
4704 (Cast): Perform constant conversions.
4706 * ecore.cs (TryImplicitIntConversion): Return literals instead of
4707 wrappers to the literals here.
4709 * expression.cs (DoNumericPromotions): long literals can converted
4710 to ulong implicity (this is taken care of elsewhere, but I was
4713 * ecore.cs (Expression.Literalize): Make the return type Literal,
4714 to improve type checking.
4716 * rootcontext.cs: Lookup for nested classes in our class hierarchy.
4718 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4720 * literal.cs: Revert code from ravi that checked the bounds. The
4721 bounds are sane by the definition of the type itself.
4723 * typemanager.cs: Fix implementation of ImplementsInterface. We
4724 need to actually look up in our parent hierarchy for interfaces
4727 * const.cs: Use the underlying type for enumerations
4729 * delegate.cs: Compute the basename for the delegate creation,
4730 that should fix the delegate test case, and restore the correct
4731 Type Lookup semantics in rootcontext
4733 * rootcontext.cs: Revert Ravi's last patch. The correct way of
4734 referencing a nested type with the Reflection API is using the "+"
4737 * cs-parser.jay: Do not require EOF token at the end.
4739 2001-12-20 Ravi Pratap <ravi@ximian.com>
4741 * rootcontext.cs (LookupType): Concatenate type names with
4742 a '.' instead of a '+' The test suite passes again.
4744 * enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
4745 field of the enumeration.
4747 * expression.cs (MemberAccess.ResolveMemberAccess): Add support for
4748 the case when the member is an EventExpr.
4750 * ecore.cs (EventExpr.InstanceExpression): Every event which is not
4751 static has an associated instance expression.
4753 * typemanager.cs (RegisterEvent): The usual workaround, now for events.
4755 (GetAddMethod, GetRemoveMethod): Workarounds, as usual.
4757 * class.cs (Event.Define): Register event and perform appropriate checks
4760 We define the Add and Remove methods even if the use provides none because
4761 in that case, we provide default implementations ourselves.
4763 Define a private field of the type of the event. This is done by the CSC compiler
4764 and we should be doing it too ;-)
4766 * typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
4767 More methods we use in code we generate.
4769 (multicast_delegate_type, delegate_type): Two separate types since the distinction
4772 (InitCoreTypes): Update accordingly for the above.
4774 * class.cs (Event.Emit): Generate code for default accessors that we provide
4776 (EmitDefaultMethod): Do the job in the above.
4778 * delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the
4781 2001-12-20 Miguel de Icaza <miguel@ximian.com>
4783 * class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
4784 builders even if we were missing one.
4786 * interface.cs, class.cs, enum.cs: When calling DefineNestedType
4787 pass the Basename as our class name instead of the Name. The
4788 basename will be correctly composed for us.
4790 * parameter.cs (Paramters): Now takes a Location argument.
4792 * decl.cs (DeclSpace.LookupType): Removed convenience function and
4793 make all the code call directly LookupType in RootContext and take
4794 this chance to pass the Location information everywhere.
4796 * Everywhere: pass Location information.
4798 2001-12-19 Miguel de Icaza <miguel@ximian.com>
4800 * class.cs (Constructor.Define): Updated way of detecting the
4801 length of the parameters.
4803 (TypeContainer.DefineType): Use basename as the type name for
4806 (TypeContainer.Define): Do not recursively define types here, as
4807 definition is taken care in order by the RootContext.
4809 * tree.cs: Keep track of namespaces in a per-file basis.
4811 * parameter.cs (Parameter.ComputeSignature): Update to use
4814 (Parameters.GetSignature): ditto.
4816 * interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
4817 instead of a TypeContainer.
4819 (Interface.SemanticAnalysis): Use `this' instead of our parent to
4820 resolve names. Because we need to be resolve in our context, not
4823 * driver.cs: Implement response files.
4825 * class.cs (TypeContainer.DefineType): If we are defined, do not
4828 (Event.Emit): Emit the code for add/remove handlers.
4829 (Event.Define): Save the MethodBuilders for add/remove.
4831 * typemanager.cs: Use pair here too.
4833 * cs-parser.jay: Replaced use of DictionaryEntry for Pair because
4834 DictionaryEntry requires the first argument to be non-null.
4836 (enum_declaration): Compute full name for registering the
4839 (delegate_declaration): Instead of using
4840 formal_parameter_list, use opt_formal_parameter_list as the list
4843 * cs-tokenizer.cs (PropertyParsing): renamed from `properties'
4844 (EventParsing): New property that controls whether `add' and
4845 `remove' are returned as tokens or identifiers (for events);
4847 2001-12-19 Ravi Pratap <ravi@ximian.com>
4849 * class.cs (Event.Define): Revamp use of EventBuilder completely. We now
4850 use MyEventBuilder only and let it wrap the real builder for us.
4852 (MyEventBuilder): Revamp constructor etc.
4854 Implement all operations that we perform on EventBuilder in precisely the same
4857 (FindMembers): Update to use the EventBuilder member.
4859 (Event.Emit): Update accordingly.
4861 2001-12-18 Ravi Pratap <ravi@ximian.com>
4863 * class.cs (MyEventBuilder.Set*): Chain to the underlying builder
4864 by calling the appropriate methods.
4866 (GetCustomAttributes): Make stubs as they cannot possibly do anything
4869 (Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
4871 2001-12-17 Ravi Pratap <ravi@ximian.com>
4873 * delegate.cs (Delegate.Populate): Check that the return type
4874 and various parameters types are indeed accessible.
4876 * class.cs (Constructor.Define): Same here.
4878 (Field.Define): Ditto.
4880 (Event.Define): Ditto.
4882 (Operator.Define): Check that the underlying Method defined itself
4883 correctly - so it's MethodBuilder should not be null.
4885 * delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
4886 expression happens to be null.
4888 * class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
4889 members but as of now we don't seem to be able to do anything really useful with it.
4891 (FindMembers): Handle events separately by returning the MyEventBuilder of the event,
4892 not the EventBuilder.
4894 2001-12-18 Miguel de Icaza <miguel@ximian.com>
4896 * cs-tokenizer.cs: Add support for defines.
4897 Add support for #if, #elif, #else, #endif
4899 (eval_var): evaluates a variable.
4900 (eval): stubbed for evaluating functions.
4902 * cs-parser.jay: Pass the defines information
4904 * driver.cs: Add --define command line option.
4906 * decl.cs: Move MemberCore here.
4908 Make it the base class for DeclSpace. This allows us to catch and
4909 report 108 and 109 for everything now.
4911 * class.cs (TypeContainer.Define): Extract all the members
4912 before populating and emit the warning 108 (new keyword required
4913 to override) instead of having each member implement this.
4915 (MemberCore.Define): New abstract method, we will be using this in
4916 the warning reporting engine in Populate.
4918 (Operator.Define): Adjust to new MemberCore protocol.
4920 * const.cs (Const): This does not derive from Expression, it is a
4921 temporary object we use to create fields, it is a MemberCore.
4923 * class.cs (Method.Define): Allow the entry point to be in a
4926 * driver.cs: Rewrite the argument handler to clean it up a bit.
4928 * rootcontext.cs: Made it just an auxiliary namespace feature by
4929 making everything static.
4931 * driver.cs: Adapt code to use RootContext type name instead of
4934 * delegate.cs: Remove RootContext argument.
4936 * class.cs: (Struct, TypeContainer, Class): Remove RootContext
4939 * class.cs (Event.Define): The lookup can fail.
4941 * cs-tokenizer.cs: Begin implementation of pre-procesor.
4943 * expression.cs: Resolve the this instance before invoking the code.
4945 2001-12-17 Miguel de Icaza <miguel@ximian.com>
4947 * cs-parser.jay: Add a production in element_access that allows
4948 the thing to become a "type" reference. This way we can parse
4949 things like "(string [])" as a type.
4951 Note that this still does not handle the more complex rules of
4955 * delegate.cs (Delegate.Populate): Register the delegage constructor builder here.
4957 * ecore.cs: (CopyNewMethods): new utility function used to
4958 assemble the list of methods from running FindMembers.
4960 (MemberLookup): Rework FindMembers so that
4962 2001-12-16 Miguel de Icaza <miguel@ximian.com>
4964 * class.cs (TypeContainer): Remove Delegates who fail to be
4967 * delegate.cs (Populate): Verify that we dont get null return
4968 values. TODO: Check for AsAccessible.
4970 * cs-parser.jay: Use basename to emit error 574 (destructor should
4971 have the same name as container class), not the full name.
4973 * cs-tokenizer.cs (adjust_int): Fit the integer in the best
4974 possible representation.
4976 Also implements integer type suffixes U and L.
4978 2001-12-15 Miguel de Icaza <miguel@ximian.com>
4980 * expression.cs (ArrayCreation.DoResolve): We need to do the
4981 argument resolution *always*.
4983 * decl.cs: Make this hold the namespace. Hold the root context as
4985 (LookupType): Move here.
4987 * enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
4989 * location.cs (Row, Name): Fixed the code, it was always returning
4990 references to the first file.
4992 * interface.cs: Register properties defined through interfaces.
4994 * driver.cs: Add support for globbing on the command line
4996 * class.cs (Field): Make it derive from MemberCore as well.
4999 2001-12-15 Ravi Pratap <ravi@ximian.com>
5001 * class.cs (Event::Define): Check that the type of the event is a delegate
5002 type else flag error #66.
5004 Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
5007 * attribute.cs (DefinePInvokeMethod): Handle named arguments and process
5008 values of EntryPoint, CharSet etc etc.
5010 Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
5012 * class.cs (FindMembers): If a method is in transit, its MethodBuilder will
5013 be null and we should ignore this. I am not sure if this is really clean. Apparently,
5014 there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
5015 which needs this to do its work.
5017 * ../errors/cs0066.cs : Add.
5019 2001-12-14 Miguel de Icaza <miguel@ximian.com>
5021 * typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
5024 * class.cs: (MethodSignature.MethodSignature): Removed hack that
5025 clears out the parameters field.
5026 (MemberSignatureCompare): Cleanup
5028 (MemberCore): New base class used to share code between MethodCore
5031 (RegisterRequiredImplementations) BindingFlags.Public requires
5032 either BindingFlags.Instace or Static. Use instance here.
5034 (Property): Refactored code to cope better with the full spec.
5036 * parameter.cs (GetParameterInfo): Return an empty array instead
5039 * class.cs (Property): Abstract or extern properties have no bodies.
5041 * parameter.cs (GetParameterInfo): return a zero-sized array.
5043 * class.cs (TypeContainer.MethodModifiersValid): Move all the
5044 method modifier validation to the typecontainer so we can reuse
5047 (MethodCore.ParameterTypes): return an empty sized array of types.
5049 (Property.Define): Test property modifier validity.
5051 Add tests for sealed/override too.
5053 (Method.Emit): abstract or extern methods have no bodies.
5055 2001-12-14 Ravi Pratap <ravi@ximian.com>
5057 * class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
5060 (Method::Define, ::Emit): Modify accordingly.
5062 * expression.cs (Invocation::OverloadResolve): Handle error # 121.
5064 (ArrayCreation::MakeByteBlob): Handle floats and doubles.
5066 * makefile: Pass in /unsafe.
5068 2001-12-13 Miguel de Icaza <miguel@ximian.com>
5070 * class.cs (MakeKey): Kill routine.
5072 * class.cs (TypeContainer.Define): Correctly define explicit
5073 method implementations (they require the full interface name plus
5076 * typemanager.cs: Deply the PtrHashtable here and stop using the
5077 lame keys. Things work so much better.
5079 This of course broke everyone who depended on `RegisterMethod' to
5080 do the `test for existance' test. This has to be done elsewhere.
5082 * support.cs (PtrHashtable): A hashtable that avoid comparing with
5083 the object stupid Equals method (because, that like fails all over
5084 the place). We still do not use it.
5086 * class.cs (TypeContainer.SetRequiredInterface,
5087 TypeContainer.RequireMethods): Killed these two routines and moved
5088 all the functionality to RegisterRequiredImplementations.
5090 (TypeContainer.RegisterRequiredImplementations): This routine now
5091 registers all the implementations required in an array for the
5092 interfaces and abstract methods. We use an array of structures
5093 which can be computed ahead of time to reduce memory usage and we
5094 also assume that lookups are cheap as most classes will not
5095 implement too many interfaces.
5097 We also avoid creating too many MethodSignatures.
5099 (TypeContainer.IsInterfaceMethod): Update and optionally does not
5100 clear the "pending" bit if we find that there are problems with
5103 (TypeContainer.VerifyPendingMethods): Update to report errors of
5104 methods that look like implementations but are not.
5106 (TypeContainer.Define): Add support for explicit interface method
5109 2001-12-12 Miguel de Icaza <miguel@ximian.com>
5111 * typemanager.cs: Keep track of the parameters here instead of
5112 being a feature of the TypeContainer.
5114 * class.cs: Drop the registration of parameters here, as
5115 InterfaceMethods are also interface declarations.
5117 * delegate.cs: Register methods with the TypeManager not only with
5118 the TypeContainer. This code was buggy.
5120 * interface.cs: Full registation here.
5122 2001-12-11 Miguel de Icaza <miguel@ximian.com>
5124 * expression.cs: Remove reducer for binary expressions, it can not
5127 * const.cs: Put here the code that used to go into constant.cs
5129 * constant.cs: Put here the code for constants, this is a new base
5132 * literal.cs: Make Literal derive from Constant.
5134 2001-12-09 Miguel de Icaza <miguel@ximian.com>
5136 * statement.cs (Return.Emit): Report error 157 if the user
5137 attempts to return from a finally block.
5139 (Return.Emit): Instead of emitting a return, jump to the end of
5142 * codegen.cs (EmitContext): ReturnValue, ReturnLabel: new
5143 LocalBuilder to store the result of the function. ReturnLabel is
5144 the target where we jump.
5147 2001-12-09 Radek Doulik <rodo@ximian.com>
5149 * cs-parser.jay: remember alias in current namespace
5151 * ecore.cs (SimpleName::DoResolve): use aliases for types or
5154 * class.cs (LookupAlias): lookup alias in my_namespace
5156 * namespace.cs (UsingAlias): add alias, namespace_or_type pair to
5158 (LookupAlias): lookup alias in this and if needed in parent
5161 2001-12-08 Miguel de Icaza <miguel@ximian.com>
5165 * rootcontext.cs: (ModuleBuilder) Made static, first step into
5166 making things static. I need this to avoid passing the
5167 TypeContainer when calling ParameterType.
5169 * support.cs (InternalParameters.ParameterType): Remove ugly hack
5170 that did string manipulation to compute the type and then call
5171 GetType. Use Parameter.ParameterType instead.
5173 * cs-tokenizer.cs: Consume the suffix for floating values.
5175 * expression.cs (ParameterReference): figure out whether this is a
5176 reference parameter or not. Kill an extra variable by computing
5177 the arg_idx during emission.
5179 * parameter.cs (Parameters.GetParameterInfo): New overloaded
5180 function that returns whether a parameter is an out/ref value or not.
5182 (Parameter.ParameterType): The type of the parameter (base,
5183 without ref/out applied).
5185 (Parameter.Resolve): Perform resolution here.
5186 (Parameter.ExternalType): The full type (with ref/out applied).
5188 * statement.cs (Using.Emit, Using.EmitExpression): Implement
5189 support for expressions on the using statement.
5191 2001-12-07 Miguel de Icaza <miguel@ximian.com>
5193 * statement.cs (Using.EmitLocalVariableDecls): Split the
5194 localvariable handling of the using statement.
5196 (Block.EmitMeta): Keep track of variable count across blocks. We
5197 were reusing slots on separate branches of blocks.
5199 (Try.Emit): Emit the general code block, we were not emitting it.
5201 Check the type of the declaration to be an IDisposable or
5202 something that can be implicity converted to it.
5204 Emit conversions if required.
5206 * ecore.cs (EmptyExpression): New utility class.
5207 (Expression.ImplicitConversionExists): New utility function.
5209 2001-12-06 Miguel de Icaza <miguel@ximian.com>
5211 * statement.cs (Using): Implement.
5213 * expression.cs (LocalVariableReference): Support read only variables.
5215 * statement.cs: Remove the explicit emit for the Leave opcode.
5216 (VariableInfo): Add a readonly field.
5218 2001-12-05 Miguel de Icaza <miguel@ximian.com>
5220 * ecore.cs (ConvCast): new class used to encapsulate the various
5221 explicit integer conversions that works in both checked and
5224 (Expression.ConvertNumericExplicit): Use new ConvCast class to
5225 properly generate the overflow opcodes.
5227 2001-12-04 Miguel de Icaza <miguel@ximian.com>
5229 * statement.cs: The correct type for the EmptyExpression is the
5230 element_type, not the variable type. Ravi pointed this out.
5232 2001-12-04 Ravi Pratap <ravi@ximian.com>
5234 * class.cs (Method::Define): Handle PInvoke methods specially
5235 by using DefinePInvokeMethod instead of the usual one.
5237 * attribute.cs (DefinePInvokeMethod): Implement as this is what is called
5238 above to do the task of extracting information and defining the method.
5240 2001-12-04 Ravi Pratap <ravi@ximian.com>
5242 * expression.cs (ArrayCreation::EmitStaticInitializers): Get rid
5243 of the condition for string type.

5255 single pointer to the current Switch statement.
5257 * statement.cs (GotoDefault, Switch): Adjust to cleaned up
5260 2001-12-03 Miguel de Icaza <miguel@ximian.com>
5264 * statement.cs (GotoDefault), cs-parser.jay: Implement `goto
5267 (Foreach.Emit): Foreach on arrays was not setting
5268 up the loop variables (for break/continue).
5270 (GotoCase): Semi-implented.
5272 2001-12-03 Ravi Pratap <ravi@ximian.com>

5322 As that share bits of the implementation. Is returns a boolean,
5323 while As returns the Type that is being probed.
5325 2001-12-01 Ravi Pratap <ravi@ximian.com>
5327 * enum.cs (LookupEnumValue): Re-write various bits, return an object value
5328 instead of a Literal - much easier.
5330 (EnumInTransit): Remove - utterly useless :-)
5332 (Populate): Re-write bits - remove duplicate code etc. The code is much neater now.
5334 * expression.cs (MemberLookup): Cope with user-defined enums when they are in transit.
5336 * enum.cs (LookupEnumValue): Auto-compute next values by going down the dependency
5337 chain when we have no associated expression.

5429 directly from ArrayData now.
5431 (ExpectInitializers): Keep track of whether initializers are mandatory
5434 (Bounds): Make it a hashtable to prevent the same dimension being
5435 recorded for every element in that dimension.

5484 2001-11-22 Miguel de Icaza <miguel@ximian.com>
5486 * statement.cs (If.Emit): Fix a bug that generated incorrect code
5487 on If. Basically, we have to return `true' (ie, we do return to
5488 our caller) only if both branches of the if return.

5491 short-circuit operators, handle them as short circuit operators.

5497 allowed a limited set of types to be handled. Now we take a
5498 unary_expression and we resolve to a type during semantic
5501 Use the grammar productions from Rhys to handle casts (this is
5502 not complete like Rhys syntax yet, we fail to handle that corner
5503 case that C# has regarding (-x), but we will get there.

5540 BindingFlags.Instance as well

5547 (Expression.ConvertExplicit): Add explicit type conversions done
5550 (Expression.ImplicitNumericConversion): Oops, forgot to test for

5554 2001-11-21 Miguel de Icaza <miguel@ximian.com>
5556 * cs-parser.jay (for_statement): Reworked the way For works: now
5557 we declare manually any variables that are introduced in
5558 for_initializer to solve the problem of having out-of-band code
5559 emition (that is what got for broken).
5561 (declaration_statement): Perform the actual variable declaration
5562 that used to be done in local_variable_declaration here.
5564 (local_variable_declaration): Do not declare anything, just pass
5565 the information on a DictionaryEntry
5567 2001-11-20 Ravi Pratap <ravi@ximian.com>
5569 * expression.cs (ArrayCreation::CheckIndices): The story continues :-) Complete

5632 we can use this elsewhere.
5634 * statement.cs: Finish implementation of foreach for single
5637 * cs-parser.jay: Use an out-of-band stack to pass information
5638 around, I wonder why I need this.
5640 foreach_block: Make the new foreach_block the current_block.
5642 * parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
5643 function used to return a static Parameters structure. Used for
5644 empty parameters, as those are created very frequently.
5646 * cs-parser.jay, class.cs: Use GetEmptyReadOnlyParameters
5648 2001-11-15 Ravi Pratap <ravi@ximian.com>
5650 * interface.cs : Default modifier is private, not public. The
5651 make verify test passes again.
5653 2001-11-15 Ravi Pratap <ravi@ximian.com>
5655 * support.cs (ReflectionParameters): Fix logic to determine

5689 2001-11-09 Miguel de Icaza <miguel@ximian.com>
5691 * enum.cs (Enum.Emit): Delay the lookup of loc until we run into

5712 * class.cs (Method.Emit): Clean up.
5714 * expression.cs (Argument.Resolve): Take another argument: the
5715 location where this argument is used. Notice that this is not
5716 part of the "Argument" class as to reduce the size of the
5717 structure (we know the approximate location anyways).

5753 * parameter.cs, expression.cs, class.cs, ecore.cs: Made all
5754 enumerations that are used in heavily used structures derive from

5757 home without adult supervision.
5759 * expression.cs (UnaryMutator): New class, used to handle ++ and
5760 -- separatedly from the other unary operators. Cleans up the
5761 code, and kills the ExpressionStatement dependency in Unary.
5763 (Unary): Removed `method' and `Arguments' from this class, making
5764 it smaller, and moving it all to SimpleCall, so I can reuse this
5765 code in other locations and avoid creating a lot of transient data
5766 strucutres when not required.

5841 of a fieldinfo using the above, when dealing with a FieldBuilder.

5931 as we had no way of defining nested enums !
5933 * rootcontext.cs : Adjust code accordingly.
5935 * typemanager.cs (AddEnumType): To keep track of enum types separately.

6230 Deal with this problem;
6232 Also, we do store negative hits on the cache (null values), so use
6233 this instead of calling t.GetInterfaces on the type everytime.

6432 the DelegateInvocation class.
6434 2001-10-17 Ravi Pratap <ravi@ximian.com>
6436 * expression.cs (New::DoResolve): Implement delegate creation fully
6437 and according to the spec.
6439 (New::DoEmit): Update to handle delegates differently.
6441 (Invocation::FullMethodDesc): Fix major stupid bug thanks to me
6442 because of which we were printing out arguments in reverse order !

6445 matches the delegate.

6499 loop and end of the loop).
6501 2001-10-15 Ravi Pratap <ravi@ximian.com>
6503 * delegate.cs (Emit): Get rid of it as there doesn't seem to be any ostensible
6504 use of emitting anything at all.
6506 * class.cs, rootcontext.cs : Get rid of calls to the same.
6508 * delegate.cs (DefineDelegate): Make sure the class we define is also sealed.

6518 (IsDelegateType): Implement helper method.
6520 * delegate.cs (DefineDelegate): Use AddDelegateType instead of AddUserType.

6523 and accordingly handle it.
6525 * delegate.cs (Populate): Take TypeContainer argument.
6526 Implement bits to define the Invoke method. However, I still haven't figured out
6527 how to take care of the native int bit :-(
6529 * cs-parser.jay (delegate_declaration): Fixed the bug that I had introduced :-)
6530 Qualify the name of the delegate, not its return type !
6532 * expression.cs (ImplicitReferenceConversion): Implement guts of implicit array
6535 (StandardConversionExists): Checking for array types turns out to be recursive.
6537 (ConvertReferenceExplicit): Implement array conversion.

6543 * cs-parser.jay (delegate_declaration): Store the fully qualified
6544 name as it is a type declaration.
6546 * delegate.cs (ReturnType, Name): Rename members to these. Make them
6549 (DefineDelegate): Renamed from Define. Does the same thing essentially,
6550 as TypeContainer::DefineType.
6552 (Populate): Method in which all the definition of the various methods (Invoke)
6555 (Emit): Emit any code, if necessary. I am not sure about this really, but let's
6558 (CloseDelegate): Finally creates the delegate.

6572 provide the proper semantic access to properties.
6574 * expression.cs (Expression::ConvertReferenceExplicit): Implement
6575 a few more explicit conversions.
6577 * modifiers.cs: `NEW' modifier maps to HideBySig.

6580 ExpressionStatement, and support the EmitStatement code path.
6582 Perform get/set error checking, clean up the interface.

6602 (This::LValueResolve): Implement.
6604 (This::Store): Remove warning, assigning to `this' in structures
6607 (Invocation::Emit): Deal with invocation of
6608 methods on value types. We need to pass the address to structure
6609 methods rather than the object itself. (The equivalent code to
6610 emit "this" for structures leaves the entire structure on the
6611 stack instead of a pointer to it).
6613 (ParameterReference::DoResolve): Compute the real index for the
6614 argument based on whether the method takes or not a `this' pointer
6615 (ie, the method is static).
6617 * codegen.cs (EmitContext::GetTemporaryStorage): Used to store
6618 value types returned from functions when we need to invoke a
6619 method on the sturcture.
6622 2001-10-11 Ravi Pratap <ravi@ximian.com>
6624 * class.cs (TypeContainer::DefineType): Method to actually do the business of
6625 defining the type in the Modulebuilder or Typebuilder. This is to take
6626 care of nested types which need to be defined on the TypeBuilder using
6629 (TypeContainer::GetClassBases): Implement. Essentially the code from the
6630 methods in RootContext, only ported to be part of TypeContainer.
6632 (TypeContainer::GetInterfaceOrClass): Ditto.
6634 (TypeContainer::LookupInterfaceOrClass, ::MakeFQN): Ditto.
6636 * interface.cs (Interface::DefineInterface): New method. Does exactly
6637 what RootContext.CreateInterface did earlier, only it takes care of nested types
6640 (Interface::GetInterfaces): Move from RootContext here and port.
6642 (Interface::GetInterfaceByName): Same here.
6644 * rootcontext.cs (ResolveTree): Re-write.

6652 instead just use the name argument passed in as it is already fully
6655 (FindMembers): Check in the Builders to TypeContainer mapping instead of the name
6656 to TypeContainer mapping to see if a type is user-defined.
6658 * class.cs (TypeContainer::CloseType): Implement.
6660 (TypeContainer::DefineDefaultConstructor): Use Basename, not Name while creating
6661 the default constructor.
6663 (TypeContainer::Populate): Fix minor bug which led to creating default constructors
6666 (Constructor::IsDefault): Fix up logic to determine if it is the default constructor
6668 * interface.cs (CloseType): Create the type here.
6670 * rootcontext.cs (CloseTypes): Re-write to recursively close types by running through
6673 Remove all the methods which are now in TypeContainer.

6684 * expression.cs (ImplicitReferenceConversion): handle null as well
6685 as a source to convert to any reference type.
6687 * statement.cs (Return): Perform any implicit conversions to
6688 expected return type.
6690 Validate use of return statement.
6692 * codegen.cs (EmitContext): Pass the expected return type here.
6694 * class.cs (Method, Constructor, Property): Pass expected return
6695 type to EmitContext.
6697 2001-10-09 Miguel de Icaza <miguel@ximian.com>
6699 * expression.cs: Make DoResolve take an EmitContext instead of a
6702 Replaced `l' and `location' for `loc', for consistency.
6704 (Error, Warning): Remove unneeded Tc argument.
6706 * assign.cs, literal.cs, constant.cs: Update to new calling
6709 * codegen.cs: EmitContext now contains a flag indicating whether
6710 code is being generated in a static method or not.
6712 * cs-parser.jay: DecomposeQI, new function that replaces the old
6713 QualifiedIdentifier. Now we always decompose the assembled
6714 strings from qualified_identifier productions into a group of
6717 2001-10-08 Miguel de Icaza <miguel@ximian.com>
6719 * rootcontext.cs: Deal with field-less struct types correctly now
6720 by passing the size option to Define Type.
6722 * class.cs: Removed hack that created one static field.
6724 2001-10-07 Miguel de Icaza <miguel@ximian.com>
6726 * statement.cs: Moved most of the code generation here.
6728 2001-10-09 Ravi Pratap <ravi@ximian.com>
6730 * expression.cs (New::DoResolve): Revert changes for array creation, doesn't
6733 (ElementAccess): Remove useless bits for now - keep checks as the spec
6736 2001-10-08 Ravi Pratap <ravi@ximian.com>
6738 * expression.cs (ElementAccess::DoResolve): Remove my crap code
6739 and start performing checks according to the spec.
6741 2001-10-07 Ravi Pratap <ravi@ximian.com>
6743 * cs-parser.jay (type_suffix*): Remove - they are redundant. Use
6744 rank_specifiers instead.

6752 2001-10-06 Ravi Pratap <ravi@ximian.com>
6754 * expression.cs (ConvertExplicitStandard): Add. Same as ConvertExplicit
6755 except that user defined conversions are not included.
6757 (UserDefinedConversion): Update to use the ConvertExplicitStandard to
6758 perform the conversion of the return type, if necessary.
6760 (New::DoResolve): Check whether we are creating an array or an object
6761 and accordingly do the needful.
6763 (New::Emit): Same here.
6765 (New::DoResolve): Implement guts of array creation.
6767 (New::FormLookupType): Helper function.
6769 2001-10-07 Miguel de Icaza <miguel@ximian.com>

6772 corresponding code generation bits to the statement classes.
6774 Added support for try/catch/finalize and throw.
6776 * cs-parser.jay: Added support for try/catch/finalize.
6778 * class.cs: Catch static methods having the flags override,
6779 virtual or abstract.
6781 * expression.cs (UserCast): This user cast was not really doing
6782 what it was supposed to do. Which is to be born in fully resolved
6783 state. Parts of the resolution were being performed at Emit time!
6787 2001-10-05 Miguel de Icaza <miguel@ximian.com>
6789 * expression.cs: Implicity convert the result from UserCast.
6791 2001-10-05 Ravi Pratap <ravi@ximian.com>
6793 * expression.cs (Expression::FindMostEncompassingType): Fix bug which
6794 prevented it from working correctly.

6801 * typemanager.cs: Make the LookupTypeContainer function static,
6802 and not per-instance.
6804 * class.cs: Make static FindMembers (the one that takes a Type
6807 * codegen.cs: Add EmitForeach here.
6809 * cs-parser.jay: Make foreach a toplevel object instead of the
6810 inline expansion, as we need to perform semantic analysis on it.

6814 * expression.cs (Expression::ImplicitUserConversion): Rename to
6815 UserDefinedConversion.

6829 * expression.cs (Cast): Record location info.
6831 (Expression::ConvertExplicit): Take location argument.
6833 (UserImplicitCast): Change name to UserCast. Take an extra constructor argument
6834 to determine if we are doing explicit conversions.
6836 (UserCast::Emit): Update accordingly.
6838 (Expression::ConvertExplicit): Report an error if everything fails.
6840 * ../errors/cs0030.cs : Add.
6842 2001-10-04 Miguel de Icaza <miguel@ximian.com>
6844 * modifiers.cs: If the ABSTRACT keyword is present, also set the
6845 virtual and newslot bits.
6847 * class.cs (TypeContainer::RegisterRequiredImplementations):
6848 Record methods we need.
6850 (TypeContainer::MakeKey): Helper function to make keys for
6851 MethodBases, since the Methodbase key is useless.
6853 (TypeContainer::Populate): Call RegisterRequiredImplementations
6854 before defining the methods.
6856 Create a mapping for method_builders_to_methods ahead of time
6857 instead of inside a tight loop.
6859 (::RequireMethods): Accept an object as the data to set into the
6860 hashtable so we can report interface vs abstract method mismatch.
6862 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6864 * report.cs: Make all of it static.
6866 * rootcontext.cs: Drop object_type and value_type computations, as
6867 we have those in the TypeManager anyways.
6869 Drop report instance variable too, now it is a global.
6871 * driver.cs: Use try/catch on command line handling.
6873 Add --probe option to debug the error reporting system with a test
6876 * report.cs: Add support for exiting program when a probe
6877 condition is reached.
6879 2001-10-03 Ravi Pratap <ravi@ximian.com>
6881 * expression.cs (Binary::DoNumericPromotions): Fix the case when
6882 we do a forcible conversion regardless of type, to check if
6883 ForceConversion returns a null.
6885 (Binary::error19): Use location to report error.
6887 (Unary::error23): Use location here too.
6889 * ../errors/cs0019.cs : Check in.
6891 * ../errors/cs0023.cs : Check in.
6893 * expression.cs (Expression.MemberLookup): Return null for a rather esoteric
6894 case of a non-null MethodInfo object with a length of 0 !
6896 (Binary::ResolveOperator): Flag error if overload resolution fails to find
6897 an applicable member - according to the spec :-)
6898 Also fix logic to find members in base types.
6900 (Unary::ResolveOperator): Same here.
6902 (Unary::report23): Change name to error23 and make first argument a TypeContainer
6903 as I was getting thoroughly confused between this and error19 :-)
6905 * expression.cs (Expression::ImplicitUserConversion): Re-write fully
6906 (::FindMostEncompassedType): Implement.
6907 (::FindMostEncompassingType): Implement.
6908 (::StandardConversionExists): Implement.
6910 (UserImplicitCast): Re-vamp. We now need info about most specific
6911 source and target types so that we can do the necessary conversions.
6913 (Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
6914 mathematical union with no duplicates.
6916 2001-10-03 Miguel de Icaza <miguel@ximian.com>
6918 * rootcontext.cs (RootContext::PopulateTypes): Populate containers
6919 in order from base classes to child classes, so that we can in
6920 child classes look up in our parent for method names and
6921 attributes (required for handling abstract, virtual, new, override
6922 constructs: we need to instrospect our base class, and if we dont
6923 populate the classes in order, the introspection might be
6924 incorrect. For example, a method could query its parent before
6925 the parent has any methods and would determine that the parent has
6926 no abstract methods (while it could have had them)).
6928 (RootContext::CreateType): Record the order in which we define the
6931 2001-10-02 Miguel de Icaza <miguel@ximian.com>
6933 * class.cs (TypeContainer::Populate): Also method definitions can
6934 fail now, keep track of this.
6936 (TypeContainer::FindMembers): Implement support for
6937 DeclaredOnly/noDeclaredOnly flag.
6939 (Constructor::Emit) Return the ConstructorBuilder.
6941 (Method::Emit) Return the MethodBuilder.
6942 Check for abstract or virtual methods to be public.
6944 * rootcontext.cs (RootContext::CreateType): Register all the
6945 abstract methods required for the class to be complete and the
6946 interface methods that must be implemented.
6948 * cs-parser.jay: Report error 501 (method requires body if it is
6949 not marked abstract or extern).
6951 * expression.cs (TypeOf::Emit): Implement.
6953 * typemanager.cs: runtime_handle_type, new global type.
6955 * class.cs (Property::Emit): Generate code for properties.
6957 2001-10-02 Ravi Pratap <ravi@ximian.com>
6959 * expression.cs (Unary::ResolveOperator): Find operators on base type
6960 too - we now conform exactly to the spec.
6962 (Binary::ResolveOperator): Same here.
6964 * class.cs (Operator::Define): Fix minor quirk in the tests.
6966 * ../errors/cs0215.cs : Added.
6968 * ../errors/cs0556.cs : Added.
6970 * ../errors/cs0555.cs : Added.
6972 2001-10-01 Miguel de Icaza <miguel@ximian.com>
6974 * cs-tokenizer.cs: Reimplemented Location to be a struct with a
6975 single integer which is really efficient
6977 2001-10-01 Ravi Pratap <ravi@ximian.com>
6979 * expression.cs (Expression::ImplicitUserConversion): Use location
6980 even in the case when we are examining True operators.

6991 (cloneable_interface): For System.ICloneable interface.
6993 * driver.cs (Driver::Driver): Initialize TypeManager's core types even before
6994 we start resolving the tree and populating types.
6996 * ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
6998 2001-10-01 Miguel de Icaza <miguel@ximian.com>
7000 * expression.cs (Expression::ExprClassFromMemberInfo,
7001 Expression::Literalize): Create literal expressions from
7002 FieldInfos which are literals.
7004 (ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
7005 type casts, because they were wrong. The test suite in tests
7008 (ImplicitNumericConversion): ushort to ulong requires a widening
7011 Int32 constant to long requires widening cast as well.
7013 * literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
7014 for integers because the type on the stack is not i4.
7016 2001-09-30 Miguel de Icaza <miguel@ximian.com>
7018 * expression.cs (report118): require location argument.
7020 * parameter.cs: Do not dereference potential null value.
7022 * class.cs: Catch methods that lack the `new' keyword when
7023 overriding a name. Report warnings when `new' is used without
7024 anything being there to override.
7026 * modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
7028 * class.cs: Only add constructor to hashtable if it is non-null
7029 (as now constructors can fail on define).
7031 (TypeManager, Class, Struct): Take location arguments.
7033 Catch field instance initialization in structs as errors.
7035 accepting_filter: a new filter for FindMembers that is static so
7036 that we dont create an instance per invocation.
7038 (Constructor::Define): Catch errors where a struct constructor is
7041 * cs-parser.jay: Pass location information for various new
7044 * delegate.cs (Delegate): take a location argument.
7046 * driver.cs: Do not call EmitCode if there were problesm in the
7047 Definition of the types, as many Builders wont be there.
7049 * decl.cs (Decl::Decl): Require a location argument.
7051 * cs-tokenizer.cs: Handle properly hex constants that can not fit
7052 into integers, and find the most appropiate integer for it.
7054 * literal.cs: Implement ULongLiteral.
7056 * rootcontext.cs: Provide better information about the location of
7057 failure when CreateType fails.
7059 2001-09-29 Miguel de Icaza <miguel@ximian.com>
7061 * rootcontext.cs (RootContext::PopulateTypes): Populates structs
7064 * expression.cs (Binary::CheckShiftArguments): Add missing type
7066 (Binary::ResolveOperator): Add type to the logical and and logical
7067 or, Bitwise And/Or and Exclusive Or code paths, it was missing
7070 (Binary::DoNumericPromotions): In the case where either argument
7071 is ulong (and most signed types combined with ulong cause an
7072 error) perform implicit integer constant conversions as well.
7074 2001-09-28 Miguel de Icaza <miguel@ximian.com>
7076 * expression.cs (UserImplicitCast): Method should always be
7078 (Invocation::BetterConversion): Simplified test for IntLiteral.
7080 (Expression::ImplicitNumericConversion): Split this routine out.
7081 Put the code that performs implicit constant integer conversions
7084 (Expression::Resolve): Become a wrapper around DoResolve so we can
7085 check eclass and type being set after resolve.
7087 (Invocation::Badness): Remove this dead function
7089 (Binary::ResolveOperator): Do not compute the expensive argumnets
7090 unless we have a union for it.
7092 (Probe::Emit): Is needs to do an isinst and then
7093 compare against null.
7095 (::CanConvert): Added Location argument. If the Location argument
7096 is null (Location.Null), then we do not report errors. This is
7097 used by the `probe' mechanism of the Explicit conversion. We do
7098 not want to generate an error for something that the user
7099 explicitly requested to be casted. But the pipeline for an
7100 explicit cast first tests for potential implicit casts.
7102 So for now, if the Location is null, it means `Probe only' to
7103 avoid adding another argument. Might have to revise this
7106 (ClassCast): New class used to type cast objects into arbitrary
7107 classes (used in Explicit Reference Conversions).
7109 Implement `as' as well.
7111 Reverted all the patches from Ravi below: they were broken:
7113 * The use of `level' as a mechanism to stop recursive
7114 invocations is wrong. That was there just to catch the
7115 bug with a strack trace but not as a way of addressing
7118 To fix the problem we have to *understand* what is going
7119 on and the interactions and come up with a plan, not
7120 just get things going.
7122 * The use of the type conversion cache that I proposed
7123 last night had an open topic: How does this work across
7124 protection domains. A user defined conversion might not
7125 be public in the location where we are applying the
7126 conversion, a different conversion might be selected
7127 (ie, private A->B (better) but public B->A (worse),
7128 inside A, A->B applies, but outside it, B->A will
7131 * On top of that (ie, even if the above is solved),
7132 conversions in a cache need to be abstract. Ie, `To
7133 convert from an Int to a Short use an OpcodeCast', not
7134 `To convert from an Int to a Short use the OpcodeCast on
7135 the variable 5' (which is what this patch was doing).
7137 2001-09-28 Ravi Pratap <ravi@ximian.com>
7139 * expression.cs (Invocation::ConversionExists): Re-write to use
7140 the conversion cache
7142 (Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
7143 cache all conversions done, not just user-defined ones.
7145 (Invocation::BetterConversion): The real culprit. Use ConversionExists
7146 to determine if a conversion exists instead of acutually trying to
7147 perform the conversion. It's faster too.
7149 (Expression::ConvertExplicit): Modify to use ConversionExists to check
7150 and only then attempt the implicit conversion.
7152 2001-09-28 Ravi Pratap <ravi@ximian.com>
7154 * expression.cs (ConvertImplicit): Use a cache for conversions
7155 already found. Check level of recursion and bail out if necessary.

7170 * codegen.cs: remove unnneded code
7172 * expression.cs: Removed BuiltinTypeAccess class
7174 Fix the order in which implicit conversions are
7177 The previous fixed dropped support for boxed conversions (adding a
7178 test to the test suite now)
7180 (UserImplicitCast::CanConvert): Remove test for source being null,
7181 that code is broken. We should not feed a null to begin with, if
7182 we do, then we should track the bug where the problem originates
7183 and not try to cover it up here.
7185 Return a resolved expression of type UserImplicitCast on success
7186 rather than true/false. Ravi: this is what I was talking about,
7187 the pattern is to use a static method as a "constructor" for
7190 Also, do not create arguments until the very last minute,
7191 otherwise we always create the arguments even for lookups that
7192 will never be performed.
7194 (UserImplicitCast::Resolve): Eliminate, objects of type
7195 UserImplicitCast are born in a fully resolved state.
7197 * typemanager.cs (InitCoreTypes): Init also value_type
7200 * expression.cs (Cast::Resolve): First resolve the child expression.
7202 (LValue): Add new method AddressOf to be used by
7205 Change the argument of Store to take an EmitContext instead of an
7206 ILGenerator, because things like FieldExpr need to be able to call
7207 their children expression to generate the instance code.
7209 (Expression::Error, Expression::Warning): Sugar functions for
7212 (Expression::MemberLookup): Accept a TypeContainer instead of a
7213 Report as the first argument.
7215 (Expression::ResolvePrimary): Killed. I still want to improve
7216 this as currently the code is just not right.
7218 (Expression::ResolveMemberAccess): Simplify, but it is still
7221 (Unary::Resolve): Catch errors in AddressOf operators.
7223 (LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
7224 index to a byte for the short-version, or the compiler will choose
7225 the wrong Emit call, which generates the wrong data.
7227 (ParameterReference::Emit, ::Store): same.
7229 (FieldExpr::AddressOf): Implement.
7231 * typemanager.cs: TypeManager: made public variable instead of
7234 * driver.cs: document --fatal.
7236 * report.cs (ErrorMessage, WarningMessage): new names for the old
7237 Error and Warning classes.
7239 * cs-parser.jay (member_access): Turn built-in access to types
7240 into a normal simplename
7242 2001-09-27 Ravi Pratap <ravi@ximian.com>
7244 * expression.cs (Invocation::BetterConversion): Fix to cope
7245 with q being null, since this was introducing a bug.
7247 * expression.cs (ConvertImplicit): Do built-in conversions first.
7249 2001-09-27 Ravi Pratap <ravi@ximian.com>
7251 * expression.cs (UserImplicitCast::Resolve): Fix bug.

7255 * class.cs (TypeContainer::AddConstructor): Fix a stupid bug
7256 I had introduced long ago (what's new ?).
7258 * expression.cs (UserImplicitCast::CanConvert): Static method to do
7259 the work of all the checking.
7260 (ConvertImplicit): Call CanConvert and only then create object if necessary.
7261 (UserImplicitCast::CanConvert, ::Resolve): Re-write.
7263 (Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
7264 that is the right way.
7266 (Invocation::MakeUnionSet): Convenience function to make unions of sets for
7267 overloading resolution. Use everywhere instead of cutting and pasting code.
7269 (Binary::ResolveOperator): Use MakeUnionSet.
7271 (UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when
7272 we have to convert to bool types. Not complete yet.
7274 2001-09-27 Miguel de Icaza <miguel@ximian.com>
7276 * typemanager.cs (TypeManager::CSharpName): support ushort.
7278 * expression.cs (Expression::TryImplicitIntConversion): Attempts
7279 to provide an expression that performsn an implicit constant int
7280 conversion (section 6.1.6).
7281 (Expression::ConvertImplicitRequired): Reworked to include
7282 implicit constant expression conversions.
7284 (Expression::ConvertNumericExplicit): Finished.
7286 (Invocation::Emit): If InstanceExpression is null, then it means
7287 that we perform a call on this.
7289 2001-09-26 Miguel de Icaza <miguel@ximian.com>
7291 * expression.cs (Unary::Emit): Remove some dead code.
7292 (Probe): Implement Resolve and Emit for `is'.
7293 (Expression::ConvertImplicitRequired): Attempt to do constant
7294 expression conversions here. Maybe should be moved to
7295 ConvertImplicit, but I am not sure.
7296 (Expression::ImplicitLongConstantConversionPossible,
7297 Expression::ImplicitIntConstantConversionPossible): New functions
7298 that tell whether is it possible to apply an implicit constant
7299 expression conversion.
7301 (ConvertNumericExplicit): Started work on explicit numeric
7304 * cs-parser.jay: Update operator constants.
7306 * parameter.cs (Parameters::GetParameterInfo): Hook up VerifyArgs
7307 (Parameters::GetSignature): Hook up VerifyArgs here.
7308 (Parameters::VerifyArgs): Verifies that no two arguments have the
7311 * class.cs (Operator): Update the operator names to reflect the
7312 ones that the spec expects (as we are just stringizing the
7315 * expression.cs (Unary::ResolveOperator): Fix bug: Use
7316 MethodInfo's ReturnType instead of LookupMethodByBuilder as the
7317 previous usage did only work for our methods.
7318 (Expression::ConvertImplicit): Handle decimal implicit numeric
7319 conversions as well.
7320 (Expression::InternalTypeConstructor): Used to invoke constructors
7321 on internal types for default promotions.
7323 (Unary::Emit): Implement special handling for the pre/post
7324 increment/decrement for overloaded operators, as they need to have
7325 the same semantics as the other operators.
7327 (Binary::ResolveOperator): ditto.

7338 (Invocation::OverloadResolve): Ditto.
7339 (Invocation::BetterFunction, BetterConversion, ConversionExists): Ditto.
7341 * everywhere : update calls to the above methods accordingly.
7343 2001-09-26 Miguel de Icaza <miguel@ximian.com>
7345 * assign.cs (Assign): Make it inherit from ExpressionStatement.
7347 * expression.cs (ExpressionStatement): New base class used for
7348 expressions that can appear in statements, so that we can provide
7349 an alternate path to generate expression that do not leave a value
7352 (Expression::Emit, and all the derivatives): We no longer return
7353 whether a value is left on the stack or not. Every expression
7354 after being emitted leaves a single value on the stack.
7356 * codegen.cs (EmitContext::EmitStatementExpression): Use the
7357 facilties of ExpressionStatement if possible.
7359 * cs-parser.jay: Update statement_expression.

7377 * everywhere : Correct calls to the above accordingly.
7379 * expression.cs (UserImplicitCast::Resolve, ::Emit): Implement.
7380 (ConvertImplicit): Do user-defined conversion if it exists.
7382 2001-09-24 Miguel de Icaza <miguel@ximian.com>
7384 * assign.cs: track location.
7385 (Resolve): Use implicit conversions on assignment.
7387 * literal.cs: Oops. Not good, Emit of short access values should

7428 * expression.cs (OverloadResolve): Improve some more to catch errors 1502 and 1503
7429 Also take an additional TypeContainer argument.

7450 * typemanager.cs: declare and load enum_type, delegate_type and
7453 * expression.cs (Expression::Emit): Now emit returns a value that
7454 tells whether a value is left on the stack or not. This strategy
7455 might be reveted tomorrow with a mechanism that would address
7456 multiple assignments.
7457 (Expression::report118): Utility routine to report mismatches on
7460 (Unary::Report23): Report impossible type/operator combination

7509 functions, throw exceptions so it is obvious that we are facing a
7512 * cs-parser.jay (invocation_expression): Pass Location information.
7514 * codegen.cs (CodeGen::Save, CodeGen::CodeGen, CodeGen::Basename):
7515 Use a basename for those routines because .NET does not like paths

7527 * expression.cs (Unary::ResolveOperator): return the child
7528 expression for expressions which are just +expr.
7529 (Unary::ResolveOperator): Return negative literals for -LITERAL
7530 expressions (otherwise they are Unary {Literal}).
7531 (Invocation::Badness): Take into account `Implicit constant
7532 expression conversions'.
7534 * literal.cs (LongLiteral): Implement long literal class.
7535 (IntLiteral): export the `Value' of the intliteral.
7537 2001-09-19 Ravi Pratap <ravi@ximian.com>
7539 * expression.cs (Binary::Emit): Finally get the emission right ! Woo!

7552 * expression.cs (Unary::Resolve): Implement.
7553 (Binary::ResolveOperator): Re-write bits to quietly continue if no overloaded
7554 operators are found instead of making noise ;-)
7555 (Unary::ResolveOperator): New method to do precisely the same thing which
7556 Binary::ResolveOperator does for Binary expressions.
7557 (Unary.method, .Arguments): Add.
7558 (Unary::OperName): Implement.
7559 (Unary::ForceConversion): Copy and Paste !
7561 * class.cs (Operator::Define): Fix a small bug for the case when we have
7564 * expression.cs (Unary::Emit): Implement. Need to find the right Opcodes

7567 2001-09-18 Miguel de Icaza <miguel@ximian.com>
7569 * expression.cs (CheckedExpr::Resolve, CheckedExpr::Emit,
7570 UnCheckedExpr::Resolve, UnCheckedExpr::Emit): Implement.

7583 (FieldExpr::Emit): Implement.
7585 * codegen.cs (EmitIf, EmitStatement, EmitBlock): Propagate whether
7586 the last instruction contains a return opcode to avoid generating
7587 the last `ret' instruction (this generates correct code, and it is
7588 nice to pass the peverify output).
7590 * class.cs (TypeContainer::EmitFieldInitializers): Implement field
7591 initializer for static and instance variables.
7592 (Constructor::Emit): Allow initializer to be null in the case of
7593 static constructors. Only emit initializer for instance
7596 (TypeContainer::FindMembers): Return a null array if there are no

7614 * class.cs: Do not emit parent class initializers for static
7615 constructors, that should be flagged as an error.
7617 2001-09-18 Ravi Pratap <ravi@ximian.com>
7619 * class.cs (RegisterMethodBuilder): Remove : it's unnecessary.
7620 Move back code into TypeContainer::Populate.

7646 * expression.cs (Expression::OverloadResolve): Drop TypeContainer
7649 (Expression::MemberLookup): Provide a version that allows to
7650 specify the MemberTypes and BindingFlags.
7652 * statement.cs (Block::GetVariableInfo): Forgot to recurse here,
7653 so it was not fetching variable information from outer blocks.
7655 * modifiers.cs: (Modifiers::TypeAttr): Invert condition on
7656 Beforefieldinit as it was buggy.
7658 * rootcontext.cs (::LookupInterfaceOrClass): Removed an Error -200
7661 * class.cs (Constructor::Emit): Only emit if block is not null.
7662 (TypeContainer::EmitDefaultConstructor): Removed routine, now we
7663 deal with this by semantically definining it as if the user had
7666 (TypeContainer::FindMembers): Removed ad-hoc hack to deal with
7667 constructors as we now "emit" them at a higher level.
7669 (TypeContainer::DefineDefaultConstructor): Used to define the
7670 default constructors if none was provided.
7672 (ConstructorInitializer): Add methods Resolve and Emit.
7674 * expression.cs: Cast to ConstructorInfo instead of MethodInfo
7676 2001-09-17 Ravi Pratap <ravi@ximian.com>

7679 the default constructor builder with our hashtable for methodbuilders
7682 * expression.cs (Invocation::OverloadResolve): Add a check for pd == null

7700 we have overloaded operators.
7701 (Binary::ResolveOperator): Implement the part which does the operator overload
7704 * class.cs (Operator::Emit): Implement.
7705 (TypeContainer::Emit): Emit the operators we have too.
7707 * expression.cs (Binary::Emit): Update to emit the appropriate code for
7708 the case when we have a user-defined operator.
7710 2001-09-17 Miguel de Icaza <miguel@ximian.com>
7712 * rootcontext.cs: Fix bug: tree.Namespaces might be null.
7714 2001-09-16 Ravi Pratap <ravi@ximian.com>

7742 2001-09-14 Miguel de Icaza <miguel@ximian.com>
7744 * class.cs (TypeContainer::FindMembers): Add support for
7746 (MethodCore): New class that encapsulates both the shared aspects
7747 of a Constructor and a Method.
7748 (Method, Constructor): Factored pieces into MethodCore.

7751 Load System assembly as well as part of the standard library.
7753 * report.cs: Allow throwing exceptions on errors for debugging.
7755 * modifiers.cs: Do not use `parent', instead use the real type
7756 container to evaluate permission settings.
7758 * class.cs: Put Ravi's patch back in. He is right, and we will
7759 have to cope with the
7761 2001-09-14 Ravi Pratap <ravi@ximian.com>
7763 * modifiers.cs (TypeAttr, MethodAttr, FieldAttr): Map protected internal to
7764 FamORAssem, not FamANDAssem.

7768 * driver.cs: Added --parse option that only parses its input files
7771 * class.cs: Reverted last change from Ravi to IsTopLevel. That is
7772 incorrect. IsTopLevel is not used to tell whether an object is
7773 root_types or not (that can be achieved by testing this ==
7774 root_types). But to see if this is a top-level *class* (not
7775 necessarly our "toplevel" container).
7777 2001-09-14 Ravi Pratap <ravi@ximian.com>

7782 2001-09-14 Ravi Pratap <ravi@ximian.com>
7784 * class.cs (TypeContainer::TypeAttr): Remove property code and move it into
7785 Modifiers.TypeAttr. This should just be a call to that method.
7787 * modifiers.cs (TypeAttr): Re-write and take an extra argument, the TypeContainer
7788 object so that we can determine if we are top-level or not.

7807 2001-09-13 Miguel de Icaza <miguel@ximian.com>
7809 * expression.cs (MemberLookup): Fruitless attempt to lookup

7813 (Invocation::EmitArguments): new function, shared by the new

7859 (TypeContainer::Populate): Keep track of MethodBuilders to Method
7862 (TypeContainer::FindMembers): Use ArrayList and then copy an array
7863 of the exact size and return that.
7865 (Class::LookupMethodByBuilder): New function that maps
7866 MethodBuilders to its methods. Required to locate the information
7867 on methods because System.Reflection bit us again.
7869 * support.cs: New file, contains an interface ParameterData and
7870 two implementations: ReflectionParameters and InternalParameters
7871 used to access Parameter information. We will need to grow this
7874 * expression.cs (Invocation::GetParameterData): implement a cache
7875 and a wrapper around the ParameterData creation for methods.

8031 (CheckBinaryOperator): Same here.
8033 * rootcontext.cs (LookupType): Add an extra lookup which simply does a lookup
8034 on the name without any prefixes of namespace names etc. This is because we
8035 already might have something already fully qualified like
8036 'System.Console.WriteLine'

8187 will is used during the tree rewriting as we resolve them during

8314 * class.cs (Property): Revamp to use the convention of making fields readonly.

8363 and re-write the code in the actions to extract the specific and
8364 general catch clauses by being a little smart ;-)
8366 * ../tests/try.cs : Fix. It's not 'finalize' my friend, it's 'finally' !
8367 Hooray, try and catch statements parse fine !

8399 (TypeContainer::indexers): New member to hold list of indexers for the
8402 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
8404 * cs-parser.jay (add_accessor_declaration): Implement action.
8405 (remove_accessor_declaration): Implement action.
8406 (event_accessors_declaration): Implement

8411 (TypeContainer::AddEvent): New method to add an event to a type
8412 (TypeContainer::events): New member to hold list of events.
8414 * cs-parser.jay (event_declaration): Implement actions.
8416 2001-08-27 Ravi Pratap <ravi@che.iitm.ac.in>
8418 * cs-parser.jay (dim_separators): Implement. Make it a string
8419 concatenating all the commas together, just as they appear.
8420 (opt_dim_separators): Modify accordingly
8421 (rank_specifiers): Update accordingly. Basically do the same
8422 thing - instead, collect the brackets here.
8423 (opt_rank_sepcifiers): Modify accordingly.
8424 (array_type): Modify to actually return the complete type string
8425 instead of ignoring the rank_specifiers.
8426 (expression_list): Implement to collect the expressions
8427 (variable_initializer): Implement. We make it a list of expressions
8428 essentially so that we can handle the array_initializer case neatly too.
8429 (variable_initializer_list): Implement.
8430 (array_initializer): Make it a list of variable_initializers
8431 (opt_array_initializer): Modify accordingly.
8433 * expression.cs (New::NType): Add enumeration to help us
8434 keep track of whether we have an object/delegate creation
8435 or an array creation.
8436 (New:NewType, New::Rank, New::Indices, New::Initializers): New
8437 members to hold data about array creation.
8438 (New:New): Modify to update NewType
8439 (New:New): New Overloaded contructor for the array creation
8442 * cs-parser.jay (array_creation_expression): Implement to call
8443 the overloaded New constructor.
8445 2001-08-26 Ravi Pratap <ravi@che.iitm.ac.in>
8447 * class.cs (TypeContainer::Constructors): Return member
8448 constructors instead of returning null.
8450 2001-08-26 Miguel de Icaza <miguel@ximian.com>
8452 * typemanager.cs (InitCoreTypes): Initialize the various core
8453 types after we have populated the type manager with the user
8454 defined types (this distinction will be important later while
8455 compiling corlib.dll)
8457 * expression.cs, literal.cs, assign.cs, constant.cs: Started work
8458 on Expression Classification. Now all expressions have a method
8459 `Resolve' and a method `Emit'.
8461 * codegen.cs, cs-parser.jay: Fixed the bug that stopped code
8462 generation from working. Also add some temporary debugging
8465 2001-08-24 Miguel de Icaza <miguel@ximian.com>
8467 * codegen.cs: Lots of code generation pieces. This is only the
8468 beginning, will continue tomorrow with more touches of polish. We
8469 handle the fundamentals of if, while, do, for, return. Others are
8470 trickier and I need to start working on invocations soon.
8472 * gen-treedump.cs: Bug fix, use s.Increment here instead of
8475 * codegen.cs (EmitContext): New struct, used during code
8476 emission to keep a context. Most of the code generation will be
8479 * cs-parser.jay: Add embedded blocks to the list of statements of
8480 this block. So code generation proceeds in a top down fashion.
8482 2001-08-23 Miguel de Icaza <miguel@ximian.com>
8484 * statement.cs: Add support for multiple child blocks.
8486 2001-08-22 Miguel de Icaza <miguel@ximian.com>
8488 * codegen.cs (EmitCode): New function, will emit the code for a
8489 Block of code given a TypeContainer and its ILGenerator.
8491 * statement.cs (Block): Standard public readonly optimization.
8492 (Block::Block constructors): Link children.
8493 (Block::Child): Child Linker.
8494 (Block::EmitVariables): Emits IL variable declarations.
8496 * class.cs: Drop support for MethodGroups here, delay until
8498 (Method::): Applied the same simplification that I did before, and
8499 move from Properties to public readonly fields.
8500 (Method::ParameterTypes): Returns the parameter types for the
8501 function, and implements a cache that will be useful later when I
8502 do error checking and the semantic analysis on the methods is
8504 (Constructor::GetCallingConvention): Renamed from CallingConvetion
8505 and made a method, optional argument tells whether this is a class
8506 or a structure to apply the `has-this' bit.
8507 (Method::GetCallingConvention): Implement, returns the calling
8509 (Method::Define): Defines the type, a second pass is performed
8510 later to populate the methods.
8512 (Constructor::ParameterTypes): implement a cache similar to the
8513 one on Method::ParameterTypes, useful later when we do semantic
8516 (TypeContainer::EmitMethod): New method. Emits methods.
8518 * expression.cs: Removed MethodGroup class from here.
8520 * parameter.cs (Parameters::GetCallingConvention): new method.

8527 (Constructor::CallingConvention): Returns the calling convention.
8528 (Constructor::ParameterTypes): Returns the constructor parameter
8531 (TypeContainer::AddConstructor): Keep track of default constructor
8532 and the default static constructor.
8534 (Constructor::) Another class that starts using `public readonly'
8535 instead of properties.
8537 (Constructor::IsDefault): Whether this is a default constructor.
8539 (Field::) use readonly public fields instead of properties also.
8541 (TypeContainer::TypeAttr, TypeContainer::AddConstructor): Keep
8542 track of static constructors; If none is used, turn on
8543 BeforeFieldInit in the TypeAttributes.
8545 * cs-parser.jay (opt_argument_list): now the return can be null
8546 for the cases where there are no arguments.
8548 (constructor_declarator): If there is no implicit `base' or
8549 `this', then invoke the default parent constructor.
8551 * modifiers.cs (MethodAttr): New static function maps a set of
8552 modifiers flags into a MethodAttributes enum
8553 (FieldAttr): renamed from `Map'. So now we have FieldAttr,
8554 MethodAttr, TypeAttr to represent the various mappings where the
8556 (FieldAttr): Map also `readonly' to `FieldAttributes.InitOnly'
8558 2001-08-19 Miguel de Icaza <miguel@ximian.com>
8560 * parameter.cs (GetParameterInfo): Fix bug where there would be no
8563 * interface.cs (PopulateIndexer): Implemented the code generator
8564 for interface indexers.
8566 2001-08-17 Miguel de Icaza <miguel@ximian.com>
8568 * interface.cs (InterfaceMemberBase): Now we track the new status
8571 (PopulateProperty): Implement property population. Woohoo! Got
8572 Methods and Properties going today.
8574 Removed all the properties for interfaces, and replaced them with
8575 `public readonly' fields.
8577 2001-08-16 Miguel de Icaza <miguel@ximian.com>
8579 * interface.cs (AddEvent, AddMethod, AddIndexer, AddProperty):
8580 initialize their hashtables/arraylists only when they are needed
8581 instead of doing this always.
8583 * parameter.cs: Handle refs and out parameters.
8585 * cs-parser.jay: Use an ArrayList to construct the arguments
8586 instead of the ParameterCollection, and then cast that to a
8589 * parameter.cs: Drop the use of ParameterCollection and use
8590 instead arrays of Parameters.
8592 (GetParameterInfo): Use the Type, not the Name when resolving
8595 2001-08-13 Miguel de Icaza <miguel@ximian.com>
8597 * parameter.cs: Eliminate the properties Name, Type and ModFlags,
8598 and instead use public readonly fields.
8600 * class.cs: Put back walking code for type containers.
8602 2001-08-11 Miguel de Icaza <miguel@ximian.com>
8604 * class.cs (MakeConstant): Code to define constants.
8606 * rootcontext.cs (LookupType): New function. Used to locate types
8609 2001-08-08 Miguel de Icaza <miguel@ximian.com>
8611 * rootcontext.cs: OH MY! My trick works! It is amazing how nice
8612 this System.Reflection code is. Kudos to Microsoft
8614 * typemanager.cs: Implement a type cache and avoid loading all
8615 types at boot time. Wrap in LookupType the internals. This made
8616 the compiler so much faster. Wow. I rule!
8618 * driver.cs: Make sure we always load mscorlib first (for
8619 debugging purposes, nothing really important).
8621 * Renamespaced things that were on `CSC' to `CIR'. Maybe I should
8622 have moved to `CSC' rather than `CIR'. Oh man! The confussion!
8624 * rootcontext.cs: Lookup types on their namespace; Lookup types
8625 on namespaces that have been imported using the `using' keyword.
8627 * class.cs (TypeContainer::TypeAttr): Virtualize.
8628 (Class::TypeAttr): Return attributes suitable for this bad boy.
8629 (Struct::TypeAttr): ditto.
8630 Handle nested classes.
8631 (TypeContainer::) Remove all the type visiting code, it is now
8632 replaced with the rootcontext.cs code
8634 * rootcontext.cs (GetClassBases): Added support for structs.
8636 2001-08-06 Miguel de Icaza <miguel@ximian.com>
8638 * interface.cs, statement.cs, class.cs, parameter.cs,
8639 rootcontext.cs, gen-treedump.cs, enum.cs, cs-parse.jay:
8640 Drop use of TypeRefs, and use strings instead.
8642 2001-08-04 Miguel de Icaza <miguel@ximian.com>
8646 * class.cs (Struct::Struct): set the SEALED flags after
8647 checking the modifiers.
8648 (TypeContainer::TypeAttr): new property, returns the
8649 TypeAttributes for a class.
8651 * cs-parser.jay (type_list): Oops, list production was creating a
8652 new list of base types.
8654 * rootcontext.cs (StdLib): New property.
8655 (GetInterfaceTypeByName): returns an interface by type name, and
8656 encapsulates error handling here.
8657 (GetInterfaces): simplified.
8658 (ResolveTree): Encapsulated all the tree resolution here.
8659 (CreateClass, GetClassBases, GetInterfaceOrClass): Create class
8662 * driver.cs: Add support for --nostdlib, to avoid loading the
8664 (Main): Do not put tree resolution here.
8666 * rootcontext.cs: Beginning of the class resolution.
8668 2001-08-03 Miguel de Icaza <miguel@ximian.com>
8670 * rootcontext.cs: Provide better error reporting.
8672 * cs-parser.jay (interface_base): set our $$ to be interfaces.
8674 * rootcontext.cs (CreateInterface): Handle the case where there
8675 are no parent interfaces.
8677 (CloseTypes): Routine to flush types at the end.
8678 (CreateInterface): Track types.
8679 (GetInterfaces): Returns an array of Types from the list of
8682 * typemanager.c (AddUserType): Mechanism to track user types (puts
8683 the type on the global type hash, and allows us to close it at the
8686 2001-08-02 Miguel de Icaza <miguel@ximian.com>
8688 * tree.cs: Removed RecordType, added RecordClass, RecordStruct and
8689 RecordInterface instead.
8691 * cs-parser.jay: Updated to reflect changes above.
8693 * decl.cs (Definition): Keep track of the TypeBuilder type that
8694 represents this type here. Not sure we will use it in the long
8695 run, but wont hurt for now.
8697 * driver.cs: Smaller changes to accomodate the new code.
8699 Call ResolveInterfaceBases, Call ResolveClassBases, Save assembly
8702 * rootcontext.cs (CreateInterface): New method, used to create
8703 the System.TypeBuilder type for interfaces.
8704 (ResolveInterfaces): new entry point to resolve the interface
8706 (CodeGen): Property, used to keep track of the code generator.
8708 2001-07-26 Miguel de Icaza <miguel@ximian.com>
8710 * cs-parser.jay: Add a second production for delegate_declaration
8713 (enum_body): Put an opt_comma here instead of putting it on
8714 enum_body or enum_member_declarations so we can handle trailing
8715 commas on enumeration members. Gets rid of a shift/reduce.
8717 (type_list): Need a COMMA in the middle.
8719 (indexer_declaration): Tell tokenizer to recognize get/set
8721 * Remove old targets.
8723 * Re-add the parser target.
8725 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8727 * cs-parser.jay: Add precendence rules for a number of operators
8728 ot reduce the number of shift/reduce conflicts in the grammar.
8730 2001-07-17 Miguel de Icaza <miguel@ximian.com>
8732 * tree.cs: moved IGenerator interface and renamed it to ITreeDump
8735 Get rid of old crufty code.
8737 * rootcontext.cs: Use this to keep track of the parsed
8738 representation and the defined types available to the program.
8740 * gen-treedump.cs: adjust for new convention.
8742 * type.cs: Split out the type manager, and the assembly builder
8745 * typemanager.cs: the type manager will live here now.
8747 * cil-codegen.cs: And the code generator here.
8749 2001-07-14 Sean MacIsaac <macisaac@ximian.com>
8751 * makefile: Fixed up for easy making.
8753 2001-07-13 Simon Cozens <simon@simon-cozens.org>
8755 * cs-parser.jay (rank_specifier): Remove a conflict by reordering
8758 (unary_expression): Expand pre_increment_expression and
8759 post_decrement_expression to reduce a shift/reduce.
8761 2001-07-11 Simon Cozens
8763 * cs-tokenizer.cs: Hex numbers should begin with a 0.
8765 Improve allow_keyword_as_indent name.
8767 2001-06-19 Miguel de Icaza <miguel@ximian.com>
8769 * Adjustments for Beta2.
8771 2001-06-13 Miguel de Icaza <miguel@ximian.com>
8773 * decl.cs: Added `Define' abstract method.
8774 (InTransit): new property, used to catch recursive definitions.
8776 * interface.cs: Implement `Define'.
8778 * modifiers.cs: Map Modifiers.constants to
8779 System.Reflection.TypeAttribute flags.
8781 * class.cs: Keep track of types and user-defined types.
8782 (BuilderInit): New method for creating an assembly
8783 (ResolveType): New function to launch the resolution process, only
8784 used by interfaces for now.
8786 * cs-parser.jay: Keep track of Classes, Structs and Interfaces
8787 that are inserted into the name space.
8789 2001-06-08 Miguel de Icaza <miguel@ximian.com>
8791 * ARGH. I have screwed up my tree so many times due to the use of
8792 rsync rather than using CVS. Going to fix this at once.
8794 * driver.cs: Objetify driver. Load assemblies, use assemblies to
8797 2001-06-07 Miguel de Icaza <miguel@ximian.com>
8799 * Experiment successful: Use System.Type rather that our own
8802 2001-05-25 Miguel de Icaza <miguel@ximian.com>
8804 * cs-parser.jay: Removed nsAliases from here.
8806 Use new namespaces, handle `using XXX;'
8808 * namespace.cs: Reimplemented namespace handling, use a recursive
8809 definition of the class. Now we can keep track of using clauses
8810 and catch invalid using clauses.
8812 2001-05-24 Miguel de Icaza <miguel@ximian.com>
8814 * gen-treedump.cs: Adapted for all the renaming.
8816 * expression.cs (Expression): this class now has a Type property
8817 which returns an expression Type.
8819 (Probe::, New::, TypeOf::, SizeOf::, Constant::): renamed from
8820 `Type', as this has a different meaning now in the base
8822 2001-05-22 Miguel de Icaza <miguel@ximian.com>
8824 * interface.cs, class.cs: Removed from all the sources the
8825 references to signature computation, as we can not do method
8826 signature computation during the parsing time, as we are not
8827 trying to solve at that point distinguishing:
8831 void a (NS.Blah x) {}
8834 Which depending on the context might be valid or not, as we do not
8835 know if Blah is the same thing as NS.Blah at that point.
8837 * Redid everything so the code uses TypeRefs now instead of
8838 Types. TypeRefs are just temporary type placeholders, that need
8839 to be resolved. They initially have a pointer to a string and the
8840 current scope in which they are used. This is used later by the
8841 compiler to resolve the reference to an actual Type.
8843 * DeclSpace is no longer a CIR.Type, and neither are
8844 TypeContainers (Class and Struct) nor Interfaces nor Enums. They
8845 are all DeclSpaces, but no Types.
8847 * type.cs (TypeRefManager): This implements the TypeRef manager,
8848 which keeps track of all the types that need to be resolved after
8849 the parsing has finished.
8851 2001-05-13 Miguel de Icaza <miguel@ximian.com>
8853 * ARGH. We are going to have to store `foreach' as a class rather
8854 than resolving it, as we need to verify error 1579 after name
8855 resolution. *OR* we could keep a flag that says `This request to
8856 IEnumerator comes from a foreach statement' which we can then use
8857 to generate the error.
8859 2001-05-10 Miguel de Icaza <miguel@ximian.com>
8861 * class.cs (TypeContainer.AddMethod): we now add methods to the
8862 MethodGroup instead of the method hashtable.
8864 * expression.cs: Add MethodGroup abstraction, which gets us one
8865 step closer to the specification in the way we handle method
8868 * cs-parser.jay (primary_expression): qualified_identifier now
8869 tried to match up an identifier to a local variable reference or
8870 to a parameter reference.
8872 current_local_parameters is now a parser global variable that
8873 points to the current parameters for the block, used during name
8876 (property_declaration): Now creates an implicit `value' argument to
8879 2001-05-09 Miguel de Icaza <miguel@ximian.com>
8881 * parameter.cs: Do not use `param' arguments as part of the
8882 signature, per the spec.
8884 2001-05-08 Miguel de Icaza <miguel@ximian.com>
8886 * decl.cs: Base class for classes, structs and interfaces. This
8887 is the "Declaration Space"
8889 * cs-parser.jay: Use CheckDef for checking declaration errors
8890 instead of having one on each function.
8892 * class.cs: Factor out some code for handling error handling in
8893 accordance to the "Declarations" section in the "Basic Concepts"
8894 chapter in the ECMA C# spec.
8896 * interface.cs: Make all interface member classes derive from
8897 InterfaceMemberBase.
8899 2001-05-07 Miguel de Icaza <miguel@ximian.com>
8901 * Many things: all interfaces are parsed and generated in
8902 gen-treedump. Support for member variables, constructors,
8903 destructors, properties, constants is there.
8905 Beginning of the IL backend, but very little done, just there for
8908 2001-04-29 Miguel de Icaza <miguel@ximian.com>
8910 * cs-parser.jay: Fix labeled statement.
8912 * cs-tokenizer.cs (escape): Escape " and ' always.
8913 ref_line, ref_name: keep track of the line/filename as instructed
8914 by #line by the compiler.
8917 2001-04-27 Miguel de Icaza <miguel@ximian.com>
8919 * System.CodeDOM/CodeBinaryOperatorExpression.cs: Rearrange enum
8920 to match the values in System.CodeDOM.
8922 Divid renamed to Divide.
8924 * System.CodeDOM/CodeForLoopStatement.cs: Always have valid
8926 (Statements.set): remove.
8928 * System.CodeDOM/CodeCatchClause.cs: always have a valid
8931 * System.CodeDOM/CodeIfStatement.cs: trueStatements and
8932 falseStatements always have valid values.
8934 * cs-parser.jay: Use System.CodeDOM now.
