Now that we can refer to instance variables, make sure they are considered lvalues.

- Minor cleanup to yesterday's changes to Sema::ObjcActOnStartOfMethodDef();
- Add Sema::CurMethodDecl, in preparation for adding ObjcIvarRefExpr.
- Add ObjcInterfaceDecl::lookupInstanceVariable(), in prep for adding ivars.
- A couple renames in ObjcInterfaceDecl, while I was in the vicinity:-)

Forgot this file from my last commit...

llvm-svn: 44009

Remove Action::ObjcActOnMethodDefinition(). Rationale:

- It is not an "action" - it is never called by the parser.
- It was only used by one method, Sema::ObjcActOnStartOfMethodDef().

As a result, the logic it embodied is now directly implemented in Sema::ObjcActOnStartOfMethodDef().

Make sure @property is allowed within a category.

Remove Sema::ObjcBuildMethodParameter().
Modify Sema::ParseParamDeclarator() to work for both ActOnStartOfFunctionDef() and ObjcActOnStartOfMethodDef().

Replace 2 method definition actions (ActOnFunctionDefBody, ActOnMethodDefBody) with 1 method definition action (ActOnFinishFunctionBody). I can't think of any reason that we would need two action hooks.

llvm-svn: 44000

Replace 3 method definition functions (ObjcParseMethodDefinition, ParseObjCInstanceMethodDefinition, ParseObjCClassMethodDefinition) with 1 method definition function (ParseObjCMethodDefinition).

Less code/confusion.

This makes DwarfRegNum to accept list of numbers instead.
Added three different "flavours", but only slightly tested on x86-32/linux.

Tweak Sema::ActOnInstanceMessage() to treat the built-in "Class" type the same as "id".

llvm-svn: 43996

This is the last 5% of the solution to teaching Sema::ActOnInstanceMessage() about private methods (r43989).

While the diff is large, the idea is very simple. When we parse method definitions (in an @implementation), we need to add them incrementally (rather than wait until the @end).

Other details...

- Renamed Sema::ActOnAddMethodsToObjcDecl() to Sema::ActOnAtEnd(). The methods are now optional arguments.
- Removed Parser::AllImplMethods (a nice cleanup).
- Added location info to ObjcImplementationDecl (since we will need it very soon:-)
- Modified message.m test to no longer allow the bogus diagnostic.

Make sure Sema::CheckIncrementDecrementOperand() removes typedefs when doing it's analysis.

Thanks to Seo Sanghyeon for his excellent (first) bug fix!

llvm-svn: 43994

llvm-svn: 43993

Teach Sema::ActOnInstanceMessage() about private methods. That is, methods declared in an implementation (but not listed in the interface).

This commit is only 95% of the bug fix. The last piece to this puzzle is to add the method decls to the implementation incrementally (as we encounter them). At the moment, the methods aren't added until we see an @end (which is too late).

I will complete this later...

Fix a basic bug (having to do with typedefs) in Sema::UsualArithmeticConversions(). 

This resuled in the following crash below.

Also modified the usual-float.c test case to capture this case.

deserialization as a temporary location for storing serialized pointer identifiers. The
definition of SerializedPtrID will likely change significantly in the future, and the
current implementation caused compilation errors on some 64-bit machines.

Since we are all working on Leopard, change the built-in MacOS X version number (__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__) to target Leopard. This is only a short term solution, until the clang driver implements the "-mmacosx-version-min" flag (which will compute this value based on the target).

that are referenced in the ASTs. This assumes that we serialize out the
decls/stmts first, and use the pointer-tracking logic in the Serializer to
determine if an IdentifierInfo (or its string key) is ever referenced.

This is a significant space optimization for serialized ASTs.

Consider the following program:

void foo(int x,int y) {
  return x > y ? x : y+1;
}

Here are the sizes of the files for the serialized ASTs:

        Full IdentifierTable: 23676 bytes
 Only-referenced Identifiers:   304 bytes.

For this simple program, this is a 77% reduction in the file size of the
serialized ASTs.

(1) serialize out top-level decls BEFORE serializing out translation unit
structures like ASTContext.

(2) deserialize out translation unit structures like ASTContext before
top-level decls by first skipping the decls in the bitstream, deserializing
ASTContext and friends, and then jumping back to the bitstream block with the
decls and then deserializing them.

Change (1) allows us to utilize the pointer-tracking system in the Serializer
to only serialize out metadata that is actually referenced by the ASTS.

Change (2) allows us to deserialize the metadata first as before, which
signficantly reduces the amount of pointer backpatching the deserializer
would have to do if the decls were deserialized first.

serialized block in the bitstream, including a block in an entirely different
nesting than the current block. This is useful for deserializing objects from
a bitstream in an order different from the order that they were serialized.

llvm-svn: 43973

Moved some of the logic in BitstreamReader::ExitBlock into a utility function
BitstreamReader::PopBlockScope. The latter is a private method. It will also
be called by Deserializer to manipulate the current "block scope."
