Build to compare two outputs of this line on fairly identical executables
nm --print-size --radix=d <executable> | grep ' .* .* ' | cut -d' ' -f 2-10
To just see the top symbols, can run e.g
nm --print-size --size-sort --radix=d <executable>

Test vectors for iterated HMAC-SHA-256 used as a salted hash algorithm with CPU stretching
