Subject: [X86][AVX512] Improve vector bool reductions
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8c3e398a3c2bf72d6b5dd0c505ef06895c1e39b1;p=llvm

[X86][AVX512] Improve vector bool reductions

As predicate masks are legal on AVX512 targets, we avoid MOVMSK in these cases, but we can just bitcast the bool vector to the integer equivalent directly - avoiding expansion of the reduction to a shuffle pattern.
