Amara Emerson	bbc71b8057	[AArch64][GlobalISel] Enable GlobalISel at -O0 by default ... Tests updated to explicitly use fast-isel at -O0 instead of implicitly. This change also allows an explicit -fast-isel option to override an implicitly enabled global-isel. Otherwise -fast-isel would have no effect at -O0.

Akira Hatanaka	87c53cc314	[AArch64, fast-isel] Fall back to SelectionDAG to select tail calls. ... Certain functions such as objc_autoreleaseReturnValue have to be called as tail-calls even at -O0. Since normal fast-isel doesn't emit calls as tail calls, we have to fall back to SelectionDAG to select calls that are marked as tail. <rdar://problem/17991614> llvm-svn: 215600	2014-08-13 23:23:58 +00:00
