Ahmed Bougacha 10768a3027 [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 llvm-svn: 231045		2015-03-03 01:09:14 +00:00
