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
Sanjay Patel	170d7eb303	[x86] remove 'nan' strings from copysign assertions; NFC ... Preemptively scrubbing these to avoid a bot fail as in PR30443: https://llvm.org/bugs/show_bug.cgi?id=30443 I'm nearly done with a patch to fix these cases, so not trying very hard to do better for the temporary win. I plan to use better checks than what the script produces for the vectorized cases. llvm-svn: 283072	2016-10-02 17:07:24 +00:00
