[Xen-devel] Any special treatment when emulating movdqu?

[Razvan Cojocaru <rzvncj@xxxxxxxxx>]

Hello,

assuming the following scenario: Windows  x64 HVM domU, rIP set just before a movdqu instruction, what happens to rIP after a call to hvm_emulate_one()? Is it possible that rIP is not incremented past the movdqu instruction in this special case (MMX instruction)? Are SSE/MMX instructions being treated in a special manner for HVM guests?

Thanks,
Razvan Cojocaru
