On clang/linux, we can use -march=native to automatically detect the. Oct 5, 2018for -o0, whether -march=native or -march= is the default still specifies the same family, so both are perfectly compatibly with -o0; Mar 11, 2025using clang 16.0 or later, i would like to know what values could be used for the -march argument.
