[cfe-commits] [PATCH] Delayed parsing for GNU attributes

[Delesley Hutchins]

This patch implements delayed parsing for GNU attributes.  The main
motivation for this patch is to implement thread safety attributes,
such as the following:

class Foo {
  int x __attribute__((guarded_by(mu)));
  int foo() __attribute__((exclusive_locks_required(mu)));
  Mutex mu;
}

Delayed parsing is now turned on for any GNU attribute that specifies
LateParsed=1 in Attr.td.  Note that support for delayed parsing is
incomplete, in that it is only enabled for attributes at the end of a
member declaration; this is due to a limitation in the current
implementation that we hope to remove at some point.

Patches for llvm and clang are attached, and can also be found at:

Cheers,

DeLesley Hutchins and Caitlin Sadowski
