Craig Topper	e4f868ea16	[AVX512] Mark EVEX VMOVSSrm and VMOVSDrm as canFoldAsLoad and isReMaterializable. llvm-svn: 277120	2016-07-29 06:06:04 +00:00
Craig Topper	07aa37039e	[AVX512] Add AVX512 run lines to some tests for scalar fma/add/sub/mul/div and regenerate. Follow up commits will bring AVX512 code up to the same quality as AVX/SSE. llvm-svn: 277118	2016-07-29 06:05:58 +00:00
James Y Knight	7c905063c5	Make utils/update_llc_test_checks.py note that the assertions are autogenerated. Also update existing test cases which appear to be generated by it and weren't modified (other than addition of the header) by rerunning it. llvm-svn: 253917	2015-11-23 21:33:58 +00:00
Ahmed Bougacha	ed3c4d1a3d	[X86] Teach load folding to accept scalar _Int users of MOVSS/MOVSD. The _Int instructions are special, in that they operate on the full VR128 instead of FR32. The load folding then looks at MOVSS, at the user, and bails out when it sees a size mismatch. What we really know is that the rm_Int instructions don't load the higher lanes, so folding is fine. This happens for the straightforward intrinsic code, e.g.: _mm_add_ss(a, _mm_load_ss(p)); Fixes PR23349.
