Subject: code question xen/arch/x86/vmx.c
Date: Thu, 11 Aug 2005 16:48:20 -0500 [thread overview]
Message-ID: <1123796900.3043.71.camel@thinkpad> (raw)
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 ?
