/* 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. */
