+; RUN: llc < %s -mtriple=x86_64-unknown-unknown -mcpu=skx  | FileCheck %s --check-prefix=ALL --check-prefix=SKX
+; RUN: llc < %s -mtriple=x86_64-unknown-unknown -mcpu=knl  | FileCheck %s --check-prefix=ALL --check-prefix=KNL
----------------
instead of -mcpu=skx , you should use -mattr which is more robust to scheduling changes:
-mattr=+avx512cd,+avx512vl

and similarly for knl:
-mattr=+avx512cd
