Manman Ren	e78d832097	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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180743 91177308-0d34-0410-b5e6-96231b3b80d8	2013-04-29 22:42:01 +00:00
Shuxin Yang	985dac6579	Memory Dependence Analysis (not mem-dep test) take advantage of "invariant.load" metadata. ... The "invariant.load" metadata indicates the memory unit being accessed is immutable. A load annotated with this metadata can be moved across any store. As I am not sure if it is legal to move such loads across barrier/fence, this change dose not allow such transformation. rdar://11311484 Thank Arnold for code review. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176562 91177308-0d34-0410-b5e6-96231b3b80d8	2013-03-06 17:48:48 +00:00
