Bruno Cardoso Lopes 65b74e1d00 Add support for 256-bit versions of VPERMIL instruction. This is a new ... instruction introduced in AVX, which can operate on 128 and 256-bit vectors. It considers a 256-bit vector as two independent 128-bit lanes. It can permute any 32 or 64 elements inside a lane, and restricts the second lane to have the same permutation of the first one. With the improved splat support introduced early today, adding codegen for this instruction enable more efficient 256-bit code: Instead of: vextractf128 $0, %ymm0, %xmm0 punpcklbw %xmm0, %xmm0 punpckhbw %xmm0, %xmm0 vinsertf128 $0, %xmm0, %ymm0, %ymm1 vinsertf128 $1, %xmm0, %ymm1, %ymm0 vextractf128 $1, %ymm0, %xmm1 shufps $1, %xmm1, %xmm1 movss %xmm1, 28(%rsp) movss %xmm1, 24(%rsp) movss %xmm1, 20(%rsp) movss %xmm1, 16(%rsp) vextractf128 $0, %ymm0, %xmm0 shufps $1, %xmm0, %xmm0 movss %xmm0, 12(%rsp) movss %xmm0, 8(%rsp) movss %xmm0, 4(%rsp) movss %xmm0, (%rsp) vmovaps (%rsp), %ymm0 We get: vextractf128 $0, %ymm0, %xmm0 punpcklbw %xmm0, %xmm0 punpckhbw %xmm0, %xmm0 vinsertf128 $0, %xmm0, %ymm0, %ymm1 vinsertf128 $1, %xmm0, %ymm1, %ymm0 vpermilps $85, %ymm0, %ymm0 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135662 91177308-0d34-0410-b5e6-96231b3b80d8		2011-07-21 01:55:47 +00:00
