Will fix correctly now that I have a testcase

building mainline GCC, PR6542

Add support for the weakref attribute. We still produce "alias weak" as llvm-gcc does, but are more strict on what uses of weakref we accept.

llvm-svn: 96992

match 'ns_returns_retained' and 'cf_returns_retained' respectively.  These
are not yet hooked up to the static analyzer.

The attributes are currently ignored.

llvm-svn: 89837

The following attributes are currently supported in C++0x attribute
lists (and in GNU ones as well):
 - align() - semantics believed to be conformant to n3000, except for
   redeclarations and what entities it may apply to
 - final - semantics believed to be conformant to CWG issue 817's proposed
   wording, except for redeclarations
 - noreturn - semantics believed to be conformant to n3000, except for
   redeclarations
 - carries_dependency - currently ignored (this is an optimization hint)

llvm-svn: 89543

unless we start implementing command-line switches which override the default
calling convention, so the effect is mostly to silence unknown attribute
warnings.)

'objc_ownership_cfretain' -> 'cf_ownership_retain'
'objc_ownership_cfrelease' -> 'cf_ownership_release'

Motivation: Core Foundation objects can be used in isolation from Objective-C,
and this forces users to reason about the separate semantics of CF objects. More
Sema support pending.

to add 'CFMakeCollectable' semantics to a method.

'objc_ownership_cfrelease'. These are the 'release' equivalents of
'objc_ownership_retain' and 'objc_ownership_cfretain' respectively.

llvm-svn: 70235

as 'objc_ownership_cfretain' except that the method acts like a CFRetain instead
of a [... retain] (important in GC modes). Checker support is wired up, but
currently only for Objective-C message expressions (not function calls).

incremented).

Objective-C method or C function increments the reference count of a passed
object.

Objective-C method or C function returns an owned an Objective-C object.

down to the ActionBase class.  This eliminates dependencies of (e.g.)
DeclSpec.h on Action.h, meaning that action.h can now include these
headers and use their types directly in the actions interfaces.

This is a refactoring to support a future change, no functionality
change.

functions from the analyzer's perspective but not the compiler's.
