For 0-lane stores, we used to generate code similar to: fmov w8, s0 str w8, [x0, x1, lsl #2] instead of: str s0, [x0, x1, lsl #2] To correct that: for store lane 0 patterns, directly match to STR <subreg>0. Byte-sized instructions don't have the special case for a 0 index, because FPR8s are defined to have untyped content. rdar://16372710 Differential Revision: http://reviews.llvm.org/D6772 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225181 91177308-0d34-0410-b5e6-96231b3b80d8
