Subject: [X86] Reduce the number of unique check prefixes in memset-nonzero.ll. NFC
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b4bf39d8f2b7b478c99baf3ae1a3b8d677a98a74;p=llvm

[X86] Reduce the number of unique check prefixes in memset-nonzero.ll. NFC

The avx512 with prefer-256-bit generates the same code as AVX2 so
just reuse that prefix.
