Some FunctionDecls do not appear at the top-level or are owned by a DeclStmt.
In calls to implicitly defined functions, a FunctionDecl is created, but only
the DeclRefExprs reference them. Since an implicitly defined function may be
called multiple times, there is no clear ownership model for such objects.

Temporary solution: when serializing out DeclRefExprs, emit an ownership bit
for the Decl. This bit is determined by querying the serializer to see if the
Decl has already been serialized. If it hasn't, emit the Decl as an owned
pointer.

I repeat: this is a hack.  This should be fixed.

Added missing deserialization case in Stmt::Create() switch statement.

No need to forward declare definition of objc_super...

llvm-svn: 44173

Finish up variadic methods/messages.

llvm-svn: 44172

Implement support for variadic methods (work in progress).

llvm-svn: 44171

Extend RewriteTest::RewriteObjCIvarRefExpr() to cope with static typing (when using -> on a type which corresponds to the implementation type).

llvm-svn: 44170

Tweak funky cast to accommodate messaging 'super'. This removes any spurious warnings.

llvm-svn: 44169

Rewrite for messaging 'super'.

The code gen. results in some spurious warnings...a cast is forthcoming.

is disabled in the sense that it will refuse to create one from a UDiv
instruction, until the code is better tested.

This fixes code like "if((bool)x) {}" for example.

- Implement ivar rewrite (patch by Fariborz).
- RewriteMessageExpr()...make implicit casts explicit with synthesizing call (removing warnings when calling objc_msgSend()).

deserialize objects if BatchReadOwnedPtrs was called more than once in the
same call chain then the second call would overwrite the SerializedPtrIDs
being used by the first call. Solved this problem by making the vector that
holds the pointer IDs local to a function call. Now BatchReadOwnedPtrs is
reentrant.

llvm-svn: 44152

Refinement to previous commit. Always cast the first argument to "id"...no need to special case self.

llvm-svn: 44149

Cast implicit "self" argument to "id". This removes all warnings associated with implicit references to self. It doesn't yet deal withexplicit references to self...

llvm-svn: 44148

"default constructed" an APSInt.  Fixed another bug in the same method
where we did not allow the NextDeclarator to be NULL.

qualifiers as part of the pointer address.

Always generate a typedef for @class. The typedef removal logic that I'm removing only made sense when we were operating on preprocess files without typedef guards. Now that we have guards, it is incorrect to ever remove one (since it may increase the likelihood that the rewritten header can't be included stand alone).

between an @ and a p, just skip whitespace.

backpatching. This original was available, but then we removed it. It is back
again to help with deserialization of FieldDecls. Because FieldDecls are
currently owned by RecordDecls, which are owned by a TagType, the type of the
FieldDecl may not be deserialized prior to deserializing the FieldDecl. Thus
backpatching solves the problem of constructing a FieldDecl that references a
type that has not yet been deserialized.

Simplified serialization of TagType to not require passing in the
SerializedPtrID. Registration of the materialized type object is done after
the CreateImpl method returns (as with other types).
