2) Fixed a test failure (which should have failed all along!).

llvm-svn: 43589

Fix two rewriter bugs:

- For @class, don't generate multiple typedefs.
- Handle the following edge case interface...

@interface NSMiddleSpecifier : NSObject {}

@end

...which was incorrectly being rewritten to...

struct _interface_NSMiddleSpecifier {
        struct _interface_NSObject _NSObject;
};
{}

Implement ObjC built-in types in MinimalAction.

This fixes the recent regression with selector-1.m and -parse-noop.

llvm-svn: 43575

Implement a more sensible strategy for ObjC built-in types (addressing a long standing FIXME in Sema::GetObjcIdType()).

This removes several gross hacks to work around the previous "lazy" behavior.

Two notes:
- MinimalActions still needs to be taught about the built-in types (This breaks one of the -noop test cases). I started this, then added a FIXME.
- I didn't convert Sema::GetObjcProtoType() yet.

llvm-svn: 43567

- Add location info to category/protocol AST's
- Rewrite categories.

llvm-svn: 43501

Remove a couple FIXME's for rewriting ObjC interfaces (which are now being rewritten properly).

llvm-svn: 43494

More support for rewriting ObjC intefaces. Still some edge cases to handle...

llvm-svn: 43493

Remove a bunch of TODO's that have been done for quite some time...

llvm-svn: 43476

This commit contains lot's of small tweaks to how we pass around and store SourceLocation's for interfaces/protocols/categories/implementations.

llvm-svn: 43475

if statements.  This implements Sema/if-empty-body.c:f3, silencing
a bogus secondary warning.  It also improve the location info for
the nullstmts created for recovery purposes.

llvm-svn: 43440

eat the terminating ;.  Fix one place where it did, allowing this
to compile without error:

struct x {
 int a;
 union {
  int b;
  float c;
 };

 int d;
};

This reduces diagnostics on PR1750 from 33 to 27.

llvm-svn: 43437

to parse stuff like:

asm volatile("1:  rex64/fxrstor (%[fx])\n\t"
       "2:\n"
       ".section .fixup,\"ax\"\n"
       "3:  movl $-1,%[err]\n"
       "    jmp  2b\n"
       ".previous\n"
       ".section __ex_table,\"a\"\n"
       "   .align 8\n"
       "   .quad  1b,3b\n"
       ".previous"
       : [err] "=r" (err)
       : [fx] "cdaSDb" (fx), "m" (*fx), "0" (0));

This reduces # diagnostics on PR1750 from 49 to 37.

resolving a crash on a .i file in PR1750.  We now generate 49 errors on the
.i file in that bug.

llvm-svn: 43433

Start rewriting ObjC interfaces. As a start, we comment out all the methods. This involved refining how the parser/AST passes/manages SourceLocations for ObjcMethodDecl's. 

llvm-svn: 43404

method.c:4:3: error: use of undeclared identifier 'BADIDENT'
        &BADIDENT, 0
         ^
method.c:5:2: error: expected '}'
};
 ^
method.c:3:14: error: to match this '{'
struct S A = {
             ^

now we only produce:

method.c:4:3: error: use of undeclared identifier 'BADIDENT'
        &BADIDENT, 0
         ^

Fix a parser bug with message expressions - need to call ParsePostfixExpressionSuffix(). 

Now were correctly allow the following...

    i = [str rangeOfString:@"]"].length;

llvm-svn: 43012

llvm-svn: 43006

- Added Sema::AddFactoryMethodToGlobalPool and Sema::AddInstanceMethodToGlobalPool and DenseMaps. This will allow us to efficiently lookup a method from a selector given no type information (for the "id" data type).

- Fixed some funky "}
                    else {" indentation in Sema::ActOnAddMethodsToObjcDecl(). I'd prefer we stay away from this style...it wastes space and isn't any easier to read (from my perspective, at least:-)

- Changed Parser::ParseObjCInterfaceDeclList() to only call Action::ActOnAddMethodsToObjcDecl() when it actually has methods to add (since most interface have methods, this is a very minor cleanup).

llvm-svn: 42957

an identifier statement. Fixed up pretty priting to print this type 
correctly.

place and making it correctly parameterized on the target.

llvm-svn: 42830

Fix a latent bug in MinimalActions (created by a recent name change).

llvm-svn: 42829

Remove Scope argument from ObjC actions that either don't need it or can now use TUScope.
Also improve a recently added comment.

llvm-svn: 42826

Make sure methods with no return type default to "id".

This fixes a crasher in Sema::MatchTwoMethodDeclarations(), identified by selector-overload.m (just added).

Added Action::ActOnTranslationUnitScope() and renamed Action::PopScope to ActOnPopScope.

Added a Translation Unit Scope instance variable to Sema (will be very useful to ObjC-related actions, since ObjC declarations are always file-scoped).
