[Xen-devel] code question xen/arch/x86/vmx.c

[Jerone Young <jyoung5@xxxxxxxxxx>]

In function vmx_dr_access in xen/arch/x86/vmx.c there is a long pointer
named "reg_p". reg_p is assigned to
 
v->arch.guest_context.debugreg[reg] = *reg_p;

in the switch case  TYPE_MOV_TO_DR.

yet it has no assignment before this? 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 ?
