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?
