2012-04-17Don't decode vperm2i128 or vperm2f128 into a shuffle if bit 3 or 7 of the ↵Craig Topper
immediate is set. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154907 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-20Factor out target shuffle mask decoding from getShuffleScalarElt and use a ↵Craig Topper
SmallVector of int instead of unsigned for shuffle mask in decode functions. Preparation for another change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153079 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-06Clean up some of the shuffle decoding code for UNPCK instructions. Add ↵Craig Topper
instruction commenting for AVX/AVX2 forms for integer UNPCKs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145924 91177308-0d34-0410-b5e6-96231b3b80d8

correctly. Add support for decoding UNPCKHPS/UNPCKHPD for AVX 128-bit and 256-bit forms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145055 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-12The VPERM2F128 is a AVX instruction which permutes between two 256-bitBruno Cardoso Lopes
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137519 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136452 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-26Recognize unpckh* masks and match 256-bit versions. The new versions areBruno Cardoso Lopes
different from the previous 128-bit because they work in lanes. Update a few comments and add testcases git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136157 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-21Add support for 256-bit versions of VPERMIL instruction. This is a newBruno Cardoso Lopes
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
2011-03-02[AVX] Fix mask predicates for 256-bit UNPCKLPS/D and implementDavid Greene
missing patterns for them. Add a SIMD test subdirectory to hold tests for SIMD instruction selection correctness and quality. ' git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126845 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-28fix a signed comparison warning.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126682 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-28[AVX] Add decode support for VUNPCKLPS/D instructions, both 128-bitDavid Greene
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126664 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-17[AVX] Recorganize X86ShuffleDecode into its own libraryDavid Greene
(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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125765 91177308-0d34-0410-b5e6-96231b3b80d8
