Subject: [X86][AVX512] Added additional shuffle+trunc test case.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=2fee386cb8c5237f5ed05f022119ec74e12cdd68;p=llvm

[X86][AVX512] Added additional shuffle+trunc test case.

An existing test should have covered this but a typo caused it to fail. I've kept both as the codegen for the typo case needs addressing as well.
