From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

is Wine with -O3 and -march=native a placebo? (lemmygrad.ml)

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?

many thanks for the explanation.

i use a ryzen 5 5600x, so march native should do something.

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.
