Hello.
According to AMD docs both FXSAVE and FXRSTOR instuctions have to generate GPF
if the memory operand is not aligned on a 16-byte boundary. Qemu in contrary
does not generate such exception in this case.
Unfortunatelly, I'm not able to write proper patch since I have no experience
in hacking qemu code (it has to be most likely fixed in the
target-i386/translate.c file, around lines 6210-6237).
regards,
M.
