llvm/test/Transforms/LoopVectorize, branch release_32 http://llvm.org https://git.amat.us/llvm/atom/test/Transforms/LoopVectorize?h=release_32 2012-11-09T07:09:44Z Add support for memory runtime check. When we can, we calculate array bounds. 2012-11-09T07:09:44Z Nadav Rotem nrotem@apple.com 2012-11-09T07:09:44Z urn:sha1:b1bf1eeede72b8c93505dd80fdf21aed0e205c7d If the arrays are found to be disjoint then we run the vectorized version of the loop. If they are not, we run the scalar code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167608 91177308-0d34-0410-b5e6-96231b3b80d8 Cost Model: add tables for some avx type-conversion hacks. 2012-11-06T19:33:53Z Nadav Rotem nrotem@apple.com 2012-11-06T19:33:53Z urn:sha1:b042868c01925dae3a1032890f591f1da78b19d3 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167480 91177308-0d34-0410-b5e6-96231b3b80d8 Code Model: Improve the accuracy of the zext/sext/trunc vector cost estimation. 2012-11-05T22:20:53Z Nadav Rotem nrotem@apple.com 2012-11-05T22:20:53Z urn:sha1:2d1528b3584ad85f2674f7db14b6ee607da678ec git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167412 91177308-0d34-0410-b5e6-96231b3b80d8 Implement the cost of abnormal x86 instruction lowering as a table. 2012-11-05T19:32:46Z Nadav Rotem nrotem@apple.com 2012-11-05T19:32:46Z urn:sha1:e623702c22e7cee4e02332b245a417a88ae6ffff git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167395 91177308-0d34-0410-b5e6-96231b3b80d8 LoopVectorize: Preserve NSW, NUW and IsExact flags. 2012-10-31T21:40:39Z Nadav Rotem nrotem@apple.com 2012-10-31T21:40:39Z urn:sha1:e57b2cbce652d45ed5516e52ad82991bfa03cfd7 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167174 91177308-0d34-0410-b5e6-96231b3b80d8 Fix a bug in the cost calculation of vector casts.
