On clang/linux, we can use -march=native to automatically detect the archite Oct 5, 2018 · For -O0, whether -march=native or -march=<generic> is the default still specifies the same family, so both are perfectly compatibly with -O0; and whenever another optimization level is specified, -march=native is beneficial to performance. Use -march=compatibility for best compatibility, or -march=native for best performance if a native executable is deployed on the same machine or on a machine with the same CPU features. I would be grateful if someone who faced a similar situation could help on this. Unless you have a specific reaso Jul 22, 2022 · What the clang equivalent (i. -march=native applies additional settings beyond -march, specific to your CPU. As I understand it, -march=native will detect the ISA and extensions to use from cpuid (which include model, family and stepping information).
