Hal Finkel 9e44a50443 Fix PPC optimizeCompareInstr swapped-sub argument handling When matching a compare with a subtract where the arguments of the compare are swapped w.r.t. the arguments of the subtract, we need to negate the predicates (or CR bit indices) of the users. This, however, is not the same as inverting the predicate (negating LT -> GT, but inverting LT -> GE, for example). The ARM backend seems to do this correctly, but when I adapted the code for the PPC backend, I introduced an error in this logic. Comparison optimization is now enabled again by default. llvm-svn: 179899		2013-04-19 22:08:38 +00:00
