Craig Topper	502fc1bdd5	[X86] Split skylake-avx512 run lines in SLP vectorizer tests to cover -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	2018-11-30 22:53:21 +00:00
Craig Topper	07f1c15995	[AVX-512] Support FCOPYSIGN for v16f32 and v8f64 ... Summary: This extends FCOPYSIGN support to 512-bit vectors. I've also added tests to show what the 128-bit and 256-bit cases look like with broadcast loads.

Sanjay Patel	d27a21874b	[x86, SSE/AVX] allow 128/256-bit lowering for copysign vector intrinsics (PR30433) ... This should fix: https://llvm.org/bugs/show_bug.cgi?id=30433 There are a couple of open questions about the codegen: 1. Should we let scalar ops be scalars and avoid vector constant loads/splats? 2. Should we have a pass to combine constants such as the inverted pair that we have here? Differential Revision: https://reviews.llvm.org/D25165 llvm-svn: 283119	2016-10-03 16:38:27 +00:00
