can someone describe what the exact changes in which OBS projects / packages will be to enable x86_64-v2-or-later-only?
osc meta prjconf -e add a line Optflags: x86_64 -march=x86_64(-v2)
My idea is that I'd like to build a set of packages that allow "legacy" machines to still boot / be useful.
This would be the time to opine for a https://download.opensuse.org/ports/x86_64/ project.
My guess / hope is, that only a few packages actually need to be built with "legacy" flags enabled (glibc of course, maybe gcc?) and most others will just keep working.
About 15 years ago I could run i586 packages on a 386DX, but that only worked because the kernel had softemulation for 387 floating point instruction. I don't see that for SSSE3/SSE4.2/POPCNT (x8664v2).
