| * | Fix issues in shuffle decoding around VPERM* instructions. Fix shuffle ↵ | Craig Topper | 2011-11-29 | 1 | -2/+2 | |
| | | | | | | | decoding for VSHUFPS/D for 256-bit types. Add pattern matching for memory forms of VPERMILPS/VPERMILPD. llvm-svn: 145390 | |||||
| * | More fixes to the X86InstComments for shuffle instructions. In particular ↵ | Craig Topper | 2011-11-22 | 1 | -12/+0 | |
| | | | | | | | add AVX flavors of many instructions and fix the destination operand for some of the existing AVX entries. llvm-svn: 145063 | |||||
| * | Fix shuffle decoding logic to handle UNPCKLPS/UNPCKLPD on 256-bit vectors ↵ | Craig Topper | 2011-11-22 | 1 | -4/+11 | |
| | | | | | | | correctly. Add support for decoding UNPCKHPS/UNPCKHPD for AVX 128-bit and 256-bit forms. llvm-svn: 145055 | |||||
| * | The VPERM2F128 is a AVX instruction which permutes between two 256-bit | Bruno Cardoso Lopes | 2011-08-12 | 1 | -0/+5 | |
| | | | | | | | | | vectors. It operates on 128-bit elements instead of regular scalar types. Recognize shuffles that are suitable for VPERM2F128 and teach the x86 legalizer how to handle them. llvm-svn: 137519 | |||||

| * | Add support for 256-bit versions of VPERMIL instruction. This is a new | Bruno Cardoso Lopes | 2011-07-21 | 1 | -0/+14 | |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 llvm-svn: 135662 | |||||
| * | [AVX] Add decode support for VUNPCKLPS/D instructions, both 128-bit | David Greene | 2011-02-28 | 1 | -4/+22 | |
| | | | | | | | | | and 256-bit forms. Because the number of elements in a vector does not determine the vector type (4 elements could be v4f32 or v4f64), pass the full type of the vector to decode routines. llvm-svn: 126664 | |||||
| * | [AVX] Recorganize X86ShuffleDecode into its own library | David Greene | 2011-02-17 | 1 | -0/+69 | |
| (LLVMX86Utils.a) to break cyclic library dependencies between LLVMX86CodeGen.a and LLVMX86AsmParser.a. Previously this code was in a header file and marked static but AVX requires some additional functionality here that won't be used by all clients. Since including unused static functions causes a gcc compiler warning, keeping it as a header would break builds that use -Werror. Putting this in its own library solves both problems at once. llvm-svn: 125765 | ||||||
