     As a practical matter, we don't know where the registers actually are,

     by setting the .regs section up so that its virtual memory address
     0 is at the place pointed to by u_ar0 (by setting the vma of the start

	214	0 is at the place pointed to by u_ar0 (by setting the vma of the start
	215	of the section to -u_ar0). GDB uses this info to locate the regs,
