Re: [Valgrind-users] Does Valgrind support AMD Ryzen 5 5600X processors

RTFM.  It's DOCUMENTED!!  https://valgrind.org/info/platforms.html
     AMD64/Linux: up to and including AVX2. This is the primary development target and tends to be well supported.

So: Intel Haswell: yes.  If "grep aes /proc/cpuinfo" is not empty, then NO,
unless you tell the compiler and disto-supplied libraries to avoid aes.
Also search for 'aes' in "$ info gcc".
