ModuleBuilder now performs llvmgen in HandleTranslationUnit.

This patch follows from the discussion on the following thread on cfe-commits:

http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20080804/006849.html

llvm-svn: 54486

Fixes <rdar://problem/6093889> Nested enum redefinition crashes sema.

llvm-svn: 54463

llvm-svn: 54440

Unify logic in return-of-stack-check (Sema) for casts and implicit casts.

llvm-svn: 54439

scimark2 on Darwin.

 - Added Sema support for asm-label on variables, which I forgot before.

 - Update CodeGen to use GlobalDeclMap to determine if static Decls
   require emission (instead of LLVM module name lookup). Important
   since the Decl name and the LLVM module name can differ.

 - <rdar://problem/6116729>

llvm-svn: 54388

  ActOnDeclarator.

llvm-svn: 54353

 - ActOnDeclarator now takes an additional parameter which is the
   AsmLabel if used. Its unfortunate that this bubbles up this high,
   but we cannot just lump it in as an attribute without mistakenly
   *accepting* it as an attribute.
 - The actual asm-label itself is, however, encoded as an AsmLabelAttr
   on the FunctionDecl.
 - Slightly improved parser error recovery on malformed asm-labels.
 - CodeGen support still missing...

llvm-svn: 54339

 - clang was erroneously accepting address-of applied to lvalue
   expressions involving pointer arithmetic.
 - clang was erroneously rejecting address-of applied to deref
   expressions of pointer-typed variables.
 - Improved existing test case.
 - Fixes: <rdar://problem/6113867>, <rdar://problem/6080158>

llvm-svn: 54326

 - Follows emission scheme used by llvm-gcc, i.e. invent an id for
   each label whose address is taken and replace each indirect goto by
   a switch to each possible target.
 - Currently we emit a switch for each indirect goto instead of
   merging them as llvm-gcc does.

llvm-svn: 54318

Finally fix PR2189.  This makes a fairly invasive but important change to
move getAsArrayType into ASTContext instead of being a method on type.
This is required because getAsArrayType(const AT), where AT is a typedef
for "int[10]" needs to return ArrayType(const int, 10).

Fixing this greatly simplifies getArrayDecayedType, which is a good sign.

llvm-svn: 54317

No functionality change.

llvm-svn: 54265

llvm-svn: 54264

 - Including possible priority argument
 - In other news, the attribute parsing code really needs a cleanup

llvm-svn: 54257

with QualTypes and Types.

llvm-svn: 54116

llvm-svn: 54114

ASTContext::getCanonicalType instead (PR2189)

llvm-svn: 54105

of doing it directly.  This is required for PR2189.

llvm-svn: 54102

llvm-svn: 54101

improve 'expression unused' diagnostics for stmtexprs.

llvm-svn: 54098

last client of the old ParseObjCProtocolReferences, so it also removes it.

llvm-svn: 54094

llvm-svn: 54093

This temporarily duplicates ParseObjCProtocolReferences, but it
will be removed in the future.

llvm-svn: 54092

llvm-svn: 54091

llvm-svn: 54090

clients allocate the memory and it delete it.

llvm-svn: 54087

First, fix canonical type handling of these, since protocol qualified id's are always
canonical.  Next, enhance SemaType to actually make these when used (instead of int)
allowing them to actually be used when appropriate.  Finally remove a bunch of logic
relating to the mishandling of canonical types with protocol-qual id's.  This fixes
rdar://5986251

llvm-svn: 54083

as well as complex float. rdar://6097730

llvm-svn: 54080

llvm-svn: 54074

problem with &&/||.  2) use canonical types for comparison instead 
of raw types. 3) emit an ext-warn for a gnu extension.

Also simplify the code to make it less nested.

llvm-svn: 54068

llvm-svn: 54067

llvm-svn: 54066

is different than C99.  This fixes the rest of rdar://6095180.

llvm-svn: 54064

llvm-svn: 54063

it does not do unary promotions (like short->int).

llvm-svn: 54058

llvm-svn: 54045

(a) removes a bogus warning.
(b) removes an undesirable usage of the ObjCMessageExpr constructor that takes an IdentifierInfo * (which I will abolish).

llvm-svn: 54042
