Thanks, but it didn't work on my side. I guessed it's due to different native.

gcc -march=native -Q --help=target|grep march
  -march=                               corei7-avx

$ ./t.sh -march=znver2
internal compiler error: verify_ssa failed

$ ./t.sh -march=icelake-server
internal compiler error: verify_ssa failed

$ ./t.sh -march=corei7-avx  ==> works fine.

I guess I can't just specify the arch option like --with-arch=znver2 for
configure, since native arch probably misses the support of some instructions
for znver2? I have no idea on x86 arch, is it possible?
