With gcc-9 the situation is very weird. It succeeds with -march=native and -mtune=generic and fails with -march=native and -mtune=native. However, the target and parameter specific options are identical, because gcc-9 has no support for alderlake. With gcc-11.3 it succeeds with -march=native (-march=alderlake) and -mtune=generic, but still succeeds if I add target and parameter specific options. It only fails if I flip -mtune=generic to -mtune=alderlake. Any hints how to debug this further?
