Ahmed Bougacha 8b5527deef [X86] Combine (cmov (and/or (setcc) (setcc))) into (cmov (cmov)). ... Fold and/or of setcc's to double CMOV: (CMOV F, T, ((cc1 | cc2) != 0)) -> (CMOV (CMOV F, T, cc1), T, cc2) (CMOV F, T, ((cc1 & cc2) != 0)) -> (CMOV (CMOV T, F, !cc1), F, !cc2) When we can't use the CMOV instruction, it might increase branch mispredicts. When we can, or when there is no mispredict, this improves throughput and reduces register pressure. These can't be catched by generic combines, because the pattern can appear when legalizing some instructions (such as fcmp une). rdar://19767934 http://reviews.llvm.org/D7634 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@231045 91177308-0d34-0410-b5e6-96231b3b80d8		2015-03-03 01:09:14 +00:00
