Author: rksimon
Date: Sat Nov 28 08:28:44 2015
New Revision: 254232
URL: http://llvm.org/viewvc/llvm-project?rev=254232&view=rev
Log:
[X86][FMA] More thorough FMA tests
Added FMADD/FMSUB/FNMADD/FNMSUB tests for all types
Added load folding tests for 512-bit vectors
NOTE: Many of the AVX512 FMA instructions don't yet commute/fold correctly
As discussed on D14909
