Eric Fiselier	70ebeabfb8	Rewrite cxa guard implementation. This patch does three main things: (1) It re-writes the cxa guard implementation to make it testable. (2) Adds support for recursive init detection on non-apple platforms. (3) It adds a futex based implementation. The futex based implementation locks and notifies on a per-object basis, unlike the current implementation which uses a global lock for all objects. Once this patch settles I'll turn it on by default when supported. llvm-svn: 359060	2019-04-24 01:47:30 +00:00

Rewrite cxa guard implementation.

This patch does three main things:
  (1) It re-writes the cxa guard implementation to make it testable.
  (2) Adds support for recursive init detection on non-apple platforms.
  (3) It adds a futex based implementation.

The futex based implementation locks and notifies on a per-object basis, unlike the
current implementation which uses a global lock for all objects. Once this patch settles
I'll turn it on by default when supported.
