When using -fprofile-generate and/or -fprofile-use, is it OK to use other optimization flags? Or are they ignored? Or do they influence the generated profile? If they do, do they do so in a good way? Or a bad way? For example, Code: -fprofile-generate -O3 -march=native -mtune=native Is that advised? Thanks!
