llvm/utils/PerfectShuffle, branch release_32 http://llvm.org https://git.amat.us/llvm/atom/utils/PerfectShuffle?h=release_32 2011-05-18T06:42:21Z In r131488 I misunderstood how VREV works. It splits the vector in half and splits each half. Therefore, the real problem was that we were using a VREV64 for a 4xi16, when we should have been using a VREV32. 2011-05-18T06:42:21Z Tanya Lattner tonic@nondot.org 2011-05-18T06:42:21Z urn:sha1:2a8eb722c7bb0fac2fe09a876f3471dcb25f465e Updated test case and reverted change to the PerfectShuffle Table. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131529 91177308-0d34-0410-b5e6-96231b3b80d8 vrev is incorrectly defined in the perfect shuffle table. The ordering is backwards (should be 0x3210 versus 0x1032) which exposed a bug when doing a shuffle on a 4xi16. I've attached a test case. 2011-05-17T20:48:40Z Tanya Lattner tonic@nondot.org 2011-05-17T20:48:40Z urn:sha1:c81c9709ef219809b0d04c55a80a8d18c7194f6a git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131488 91177308-0d34-0410-b5e6-96231b3b80d8 Teach PerfectShuffle to not generate files with embedded tab characters. 2010-10-14T00:12:49Z Jim Grosbach grosbach@apple.com 2010-10-14T00:12:49Z urn:sha1:41045ba731f37fb6bef980cdc63b0a8538b6c8ca git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116458 91177308-0d34-0410-b5e6-96231b3b80d8 Provide proper masks for neon perfect shuffle table. 2009-09-25T22:52:29Z Anton Korobeynikov asl@math.spbu.ru 2009-09-25T22:52:29Z urn:sha1:58cd84dc775ec4b4fb11e7d0e383449dfd81cf11 I definitely need to read documentation better :( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82813 91177308-0d34-0410-b5e6-96231b3b80d8 Add lowering of ARM 4-element shuffles to multiple instructios via perfectshuffle-generated table. 2009-08-21T12:41:24Z Anton Korobeynikov asl@math.spbu.ru 2009-08-21T12:41:24Z urn:sha1:1c8e581832440a114c9587d41473d107de4cac74 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79624 91177308-0d34-0410-b5e6-96231b3b80d8 Add simple cost model to perfect shuffle.
