Subject: [AVX512] Replace scalar fp arithmetic intrinsics with native IR in an AVX512 test... 
X-Git-Tag: llvmorg-4.0.0-rc1~13695
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9161e4ec220478ef03d78e5e1979cf5f0c8da0a6;p=platform%2Fupstream%2Fllvm.git

[AVX512] Replace scalar fp arithmetic intrinsics with native IR in an AVX512 test. The intrinsics aren't lowered to AVX512 instructions.

The intrinsics really should be removed and autoupgraded.
