[Qemu-devel] FXSAVE doesn't #GP on alignment error

[Vegard Nossum]

Hello,

I am not sure if this should be treated as an error or not (it
definitely isn't critical), but I'll post it as an extra information
if it is useful or you think it should be fixed.

According to Intel manuals, the FXSAVE instruction requires the
argument to be 16-byte aligned. On a real machine, violating this
constraint results in a #GP. From experience, qemu will not enforce
this alignment constraint.


Kind regards,
