[Lldb-commits] [PATCH] D117928: [lldb] Disable tests for x86 that uses write command on XMM registers

mgorny added a comment.

Ok, so to summarize: there's some CPU families where setting `xmm2..xmm9` via ptrace doesn't work for some reason? That's quite weird. Could it be an `xsave` bug perhaps?

FWICS the corresponding read test passes, so apparently setting them directly within the program works.

Could you tell us what CPU exactly is this? Ideally paste `/proc/cpuinfo`. I'm pretty sure this test passed successfully on my old Athlon64 that definitely didn't have AVX (or SSE3). Unfortunately, I can't retest it anymore since it died almost 2 years ago.
