For nerd purposes I’ve been trying to custom compile Wine to see if i can squeeze some performance out of it, i pulled out the -g flag and put in its place -O3 with march native. i don’t know how to benchmark properly to see if there at least a marginal gain, so idk if it is a placebo or not. tried to search for articles in the subject but found none
has anyone tried it or know an article that explored the subject?
It fully depends on the code. If the code in question does not do the kinds of calculations that can benefit from SIMD instructions,
march=native
will do absolutely nothing for you, no matter how special or new your CPU might be.I doubt WINE does many things that would benefit from SIMD but the only way to know for sure is to test it out.
