Manman Ren	1a5ff287fd	TBAA: remove !tbaa from testing cases if not used. ... This will make it easier to turn on struct-path aware TBAA since the metadata format will change. llvm-svn: 180796	2013-04-30 17:52:57 +00:00
Pekka Jaaskelainen	d3c90e132a	Call the potentially costly isAnnotatedParallel() only once. ... Made the uniform write test's checks a bit stricter. llvm-svn: 180119	2013-04-23 16:44:43 +00:00
Pekka Jaaskelainen	6f2f66b63f	Refuse to (even try to) vectorize loops which have uniform writes, ... even if erroneously annotated with the parallel loop metadata. Fixes Bug 15794: "Loop Vectorizer: Crashes with the use of llvm.loop.parallel metadata" llvm-svn: 180081	2013-04-23 08:08:51 +00:00
