Could the OpenQA 32bit machines modified to emulate a non-SSE2 cpu? That would get the trouble visible and fast.
But agreed on QT5 and ruby, their 32bit builds should be enforced NO SSE2 at all, or we need different 32bit packages e.g i586 and i686, with i586 on the install medium.
Even for i686, you must deactivate unconditional SSE.
"qemu-kvm -cpu pentium2 -cdrom i686.iso" boots, and /proc/cpuinfo claims to not support sse2 nor sse, but it does not expose the bug (YaST2 starts up just fine), so I guess it actually does support sse and sse2 (which is logical, because the CPU is not emulated but "passed through" from the host, it's just the cpuid commands that are emulated probably).
So using this in openqa does not really help.
Affirmed, sadly, on Core-i7 with "qemu-kvm -cpu pentium" all SSE4 codes where valid and available for use. No error messages at all. Sh.t, so much for emulated validation, at least with qemu.
