* Revert "Temporarily Revert:"Alexey Bataev2019-11-141-26/+51
| | | | | | | | | | | | This reverts commit e511c4b0dff1692c267addf17dce3cebe8f97faa: Temporarily Revert: "[SLP] Generalization of stores vectorization." "[SLP] Fix -Wunused-variable. NFC" "[SLP] Vectorize jumbled stores." after fixing the problem with compile time.

| | | | | | | | | | | | | | | | | "[SLP] Generalization of stores vectorization." "[SLP] Fix -Wunused-variable. NFC" "[SLP] Vectorize jumbled stores." As they're causing significant (10-30x) compile time regressions on vectorizable code. The primary cause of the compile-time regression is f228b5371647f471853c5fb3e6719823a42fe451. This reverts commits: f228b5371647f471853c5fb3e6719823a42fe451 5503455ccb3f5fcedced158332c016c8d3a7fa81 21d498c9c0f32dcab5bc89ac593aa813b533b43a
* [SLP] Generalization of stores vectorization.Alexey Bataev2019-10-291-26/+51
| | | | | | | | | Stores are vectorized with maximum vectorization factor of 16. Patch tries to improve the situation and use maximal vectorization factor. Reviewers: spatel, RKSimon, mkuper, hfinkel Differential Revision: https://reviews.llvm.org/D43582
* Revert "Temporarily Revert "Add basic loop fusion pass.""Eric Christopher2019-04-171-0/+863
| | | | | | | | The reversion apparently deleted the test/Transforms directory. Will be re-reverting again. llvm-svn: 358552
* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-863/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* Temporarily Revert "[X86][SLP] Enable SLP vectorization for 128-bit ↵Eric Christopher2019-02-201-32/+64
| | | | | | | | | | | | | | | | horizontal X86 instructions (add, sub)" As this has broken the lto bootstrap build for 3 days and is showing a significant regression on the Dither_benchmark results (from the LLVM benchmark suite) -- specifically, on the BENCHMARK_FLOYD_DITHER_128, BENCHMARK_FLOYD_DITHER_256, and BENCHMARK_FLOYD_DITHER_512; the others are unchanged. These have regressed by about 28% on Skylake, 34% on Haswell, and over 40% on Sandybridge. This reverts commit r353923. llvm-svn: 354434
* [X86][SLP] Enable SLP vectorization for 128-bit horizontal X86 instructions ↵Anton Afanasyev2019-02-131-64/+32
| | | | | | | | | | | | | (add, sub) Try to use 64-bit SLP vectorization. In addition to horizontal instrs this change triggers optimizations for partial vector operations (for instance, using low halfs of 128-bit registers xmm0 and xmm1 to multiply <2 x float> by <2 x float>). Fixes llvm.org/PR32433 llvm-svn: 353923
* [X86] Split skylake-avx512 run lines in SLP vectorizer tests to cover ↵Craig Topper2018-11-301-1/+2
| | | | | | | | -mprefer=vector-width=256 and -mprefer-vector-width=512. This will make these tests immune if we ever change the default behavior of -march=skylake-avx512 to prefer 256 bit vectors. llvm-svn: 348046
