Upstream does not care and Fedora seems unable to address this issue.According to my system, it has SSSE3. Is it SSE3?That's what my question actually was about.
https://en.wikipedia.org/wiki/SSE3#CPUs_with_SSE3
I see ssse3 on all my x86_64ers, I see sse3 on my 32bit atoms, but I don't know if ssse3 implies sse3 and I don't know what -msse3 actually does to the instruction set when being used on x86_64ers and which impact it has
https://en.wikipedia.org/wiki/SSE3#New_instructions
(-msse3 is not part of Fedora's gcc implicit CFLAGS).
and that is really sad because it wastes for 99.9% of users performance and hence i override the builds of perormance relevant software since years with optimized falgs while hat -fstack-protector-all in use long before Fedora supported and switched to -fstack-protector-strong
in other words: you get the small performance impact of hardening back by better utilize your existing hardware instead castrate your whole software to nostalgic decades
any system not older than 10 years has SSE3 and frankly systems older than 10 years are hardly a traget for Fedora at allSo, Fedora or Linux as a resort to escape Windows on old HW is not a Fedora target anymore?
come on and install a recent Fedora on such old machines, guess what SSE3 or not is your smallest problem
