/* The registers don't have a fixed offset within ucontext because the
   orginal ucontext only contained the regs pointer.  Also with the
   addition of VMX to the register state the mcontext may require
   stronger alignment (16) then the containing ucontext (4).  All access
   to register state (pt_regs/mcontext) must be indirect via the regs
   (uc_regs) pointer.  This means we can't test the PPC32 mcontext
   register offsets here.  */
