This should only make a difference in programs that use a lot of the vector ALU instructions like BFI_INT and BIT_ALIGN. There is a slight improvement in the phatk bitcoin mining kernel with this patch on Evergreen (vector size == 1): Before: 1173 Instruction Groups / 9520 dwords After: 1167 Instruction Groups / 9510 dwords Reviewed-by: Reviewed-by: Vincent Lejeune<vljn at ovi.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184819 91177308-0d34-0410-b5e6-96231b3b80d8
