So you're trying to execute an instruction that we don't support.

Actually though, that is an AVX encoded SHLX instruction, which we do 
support in the current release, so you just need to upgrade.

Alternatively, just don't compile with -march=native but rather choose 
some older processor to target.

It's not a warning, it's a hard error ;-)
