What is the intent of reg_p? It also is assigned in the switch case TYPE_MOVE_FROM_DR...yet it's not used for anything ? It's assigned to in the macro CASE_GET_REG_P. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
