--- Comment #104 from Petr <kobalicek.p...@gmail.com> ---
If you use a distribution such as Gentoo with AVX-512 enabled globally you
basically cannot use valgrind as it doesn't matter what valgrind advertises -
all the code is already using AVX-512. And this of course also happens when you
use `-march=naive`, etc...

Still not sure why AVX-512 is so big deal. I mean is it the decoding or
supporting wider operations? It's like extending AVX2 to use wider vectors and
masking - that would cover maybe 95% of AVX-512.
