Hi,
there's been rumors and confusion about ALP raising the x86_64
architecture level to v3 which requires CPUs with AVX2 support and
how this will affect openSUSE Factory. Sofar openSUSE Factory was
supposed to be not affected but I think it makes sense to re-consider
the current -v1 usage given what other distros are doing.
Thus I would propose raising the x86_64 architecture level to x86-64-v2
for openSUSE Factory. v2 requires CMPXCHG16B, [SL]AHF, POPCNT and
SSE4_2 (and the predecessor SSE extensions) but not AVX, BMI or FMA.
Historically the 32bit multilibs built in the i586 tree kept using
i586 in openSUSE Factory while for SLE15 we are using x86-64-v1
there as well given there's no support for Hardware not supporting
x86-64 there. This is not a proposal to change that part, so the
32bit port should be unaffected (I notice opensuse.org refers to
the 32bit port as i686 though)
Comments welcome.
Richard.
