Charlie Turner 7968b981bf [ARM] Don't pessimize i32 vselect. ... The underlying issues surrounding codegen for 32-bit vselects have been resolved. The pessimistic costs for 64-bit vselects remain due to the bad scalarization that is still happening there. I tested this on A57 in T32, A32 and A64 modes. I saw no regressions, and some improvements. From my benchmarks, I saw these improvements in A57 (T32) spec.cpu2000.ref.177_mesa 5.95% lnt.SingleSource/Benchmarks/Shootout/strcat 12.93% lnt.MultiSource/Benchmarks/MiBench/telecomm-CRC32/telecomm-CRC32 11.89% I also measured A57 A32, A53 T32 and A9 T32 and found no performance regressions. I see much bigger wins in third-party benchmarks with this change Differential Revision: http://reviews.llvm.org/D14743 llvm-svn: 253349		2015-11-17 17:25:15 +00:00
