Supporting a few more MOV variants would be nice at least. We've got away with MOVQ as our only supported MMX instruction for a long time... We'd just need to extend the get_fpu() callback to understand and check for X86_EMUL_sseN/avx. -- Keir > Jan > > > _______________________________________________ > Xen-devel mailing list > Xen-devel@xxxxxxxxxxxxxxxxxxx > http://lists.xensource.com/xen-devel _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
