Fariborz Jahanian 29082a5f1d objc: If a method is not implemented in the category implementation but
has been declared in its primary class, superclass,
or in one of their protocols, no need to issue unimplemented method.

Kaelyn Uhrain 4e8942c139 Make the callback object to Sema::CorrectTypo mandatory.

Douglas Gregor 70f449bf41 Whenever Sema attempts to look in the global method pool, try to load
additional data from the external Sema source. This properly copes
with modules that are imported after we have already searched in the
global method pool for a given selector. For PCH, it's a slight
pessimization to be fixed soon.

Douglas Gregor e171601ff6 Rework the external Sema source's ReadMethodPool() so that it doesn't
return pre-built lists. Instead, it feeds the methods it deserializes
to Sema so that Sema can unique them, which keeps the chains shorter.

Douglas Gregor c454afedff Factor out the addition of a method into the global method pool, and
teach it to always add the new method at the *end* of the list rather
than as the second element in the list.

llvm-svn: 146722
2011-12-16 03:12:41 +00:00
Douglas Gregor 16408325af Move ObjCInterfaceDecl's "EndLoc" into DefinitionData, since it only
applies to an actual definition. Plus, clarify the purpose of this
field and give the accessor a different name, since getLocEnd() is
supposed to be the same as getSourceRange().getEnd().

Douglas Gregor dc9166c8e1 Keep track of all declarations of an Objective-C class (both forward
declarations and definitions) as ObjCInterfaceDecls within the same
redeclaration chain. This new representation matches what we do for
C/C++ variables/functions/classes/templates/etc., and makes it
possible to answer the query "where are all of the declarations of
this class?"

llvm-svn: 146679
2011-12-15 20:29:51 +00:00
Douglas Gregor c0ac7d688e Move the definition-specific data of ObjCInterfaceDecl into a
separately-allocated DefinitionData structure, which we manage the
same way as CXXRecordDecl::DefinitionData. This prepares the way for
making ObjCInterfaceDecls redeclarable, to more accurately model
forward declarations of Objective-C classes and eliminate the mutation
of ObjCInterfaceDecl that causes us serious trouble in the AST reader.

Note that ObjCInterfaceDecl's accessors are fairly robust against
being applied to forward declarations, because Clang (and Sema in
particular) doesn't perform RequireCompleteType/hasDefinition() checks
everywhere it has to. Each of these overly-robust cases is marked with
a FIXME, which we can tackle over time.

Argyrios Kyrtzidis 8ad3bab505 [libclang] Fix operations (token annotation, getting cursor, etc.) with a file region
inside an objc container that "contains" other file-level declarations.

When getting the array of file-level declarations that overlap with a file region,
we failed to report that the region overlaps with an objc container, if
the container had other file-level declarations declared lexically inside it.

Fix this by marking such declarations as "isTopLevelDeclInObjCContainer" in the AST
and handling them appropriately.

Douglas Gregor 4123a86fae Use Sema::RequireCompleteType to check for the completeness of
Objective-C classes. This has two purposes: to consistently provide
"forward declaration here" notes when we hit an incomplete type, and
to give LLDB a chance to complete the type.

Argyrios Kyrtzidis b97a4025ff [PCH] When completing an objc forward reference, do not serialize the chain of its categories because
it is going to be rewritten (and the chain will be serialized again), otherwise we may form a cycle in its
categories list when deserializing.

Also introduce ASTMutationListener::CompletedObjCForwardRef to notify that a forward reference
was completed; using Decl's isChangedSinceDeserialization/setChangedSinceDeserialization
is bug inducing and kinda gross, we should phase it out.

Fixes infinite loop in rdar://10418538.

Argyrios Kyrtzidis bd8b150dfc Introduce ASTConsumer::HandleTopLevelDeclInObjCContainer which accepts
top-level declarations that occurred inside an ObjC container.

This is useful to keep track of such decls otherwise when e.g. a function
is declared inside an objc interface, it is not passed to HandleTopLevelDecl
and it is not inside the DeclContext of the interface that is returned.

Richard Smith caf3390d44 Constant expression evaluation refactoring:
- Remodel Expr::EvaluateAsInt to behave like the other EvaluateAs* functions,
   and add Expr::EvaluateKnownConstInt to capture the current fold-or-assert

 - Factor out evaluation of bitfield bit widths.
 - Fix a few places which would evaluate an expression twice: once to determine
   whether it is a constant expression, then again to get the value.

Argyrios Kyrtzidis b8c3aaf479 Allow getting all source locations of selector identifiers in a ObjCMethodDecl.
Instead of always storing all source locations for the selector identifiers
we check whether all the identifiers are in a "standard" position; "standard" position is

  -Immediately before the arguments: -(id)first:(int)x second:(int)y;
  -With a space between the arguments: -(id)first: (int)x second: (int)y;
  -For nullary selectors, immediately before ';': -(void)release;

In such cases we infer the locations instead of storing them.
