tool for ISA usage statistics within ELF binaries?

[Mo Zhou <lumin@debian.org>]

Hi mentors,

do you know if there is a static ELF analysing tool, that makes
statistics on the usage of different ISAs? maybe something on top
of a disassembler?

actually, I'd like to know if an ELF binary has got more, say
AVX instructions after recompiling with -march=native,
-ftree-vectorization, -O3, etc.

thanks in advance
