When -march=cascadelake is added, we generate
vmovdqa x(%rip), %ymm0
vpcmpq $1, x(%rip), %ymm0, %k0
vpmovm2q %k0, %ymm0
vmovdqa %ymm0, x(%rip)
instead of
vmovdqa x(%rip), %ymm1
vmovdqa x(%rip), %ymm0
vpcmpgtq %ymm1, %ymm0, %ymm0
vmovdqa %ymm0, x(%rip)
Compile avx2-vpcmpgtq-1.c with -fno-fuse-ops-with-volatile-access to
generate vpcmpgtq instead of vpcmpq.
