Though this instruction is not legal for machines with SSSE3 and lower. The fix: In EltsFromConsecutiveLoads, if we have passed legalize stage, we check whether nodes it emits are legal. P.S.: If you get failure in time from 12:00 and till 22:00 (UTC-8), perhaps I'll slow with response, so you better reject this commit. Thanks! ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@197779 91177308-0d34-0410-b5e6-96231b3b80d8		2013-12-20 04:29:56 +00:00
