Chad Rosier	70d54ac848	[AArch64] Improve cost model to handle sdiv by a pow-of-two. This patch improves the target-specific cost model to better handle signed division by a power of two. The immediate result is that this enables the SLP vectorizer to do a better job. http://reviews.llvm.org/D5469 PR20714 llvm-svn: 218607	2014-09-29 13:59:31 +00:00
