Richard Sandiford ce09e57709 [SystemZ] Set usaAA to true ... useAA significantly improves the handling of vector code that has TBAA information attached. It also helps other cases, as shown by the testsuite changes here. The only real downside I've seen is that it interferes with MergeConsecutiveStores. The problem is that that optimization works top down, starting at the first store in the chain, and looks for cases where the chain result is only used by a single related store. These related stores don't alias, so useAA will have rewritten all the later stores to use a different chain input (typically the same one as the first store). I think the advantages outweigh the disadvantages though, so for now I've just disabled alias analysis for the unaligned-01.ll test. llvm-svn: 193521		2013-10-28 13:53:37 +00:00
