[PATCH] D39450: [X86] Add AVX512 support to X86FastISel::fastMaterializeFloatZero.

[Craig Topper via Phabricator via llvm-commits]

craig.topper created this revision.

[X86] Teach fast isel to handle i64 sitofp with AVX.

For some reason we only handled i32 sitofp with AVX. But with SSE only we support i64 so we should do the same with AVX.
