     registers might be at positive or negative (or both) displacements
     from *u_ar0.  The other is that u_ar0 is sometimes an absolute address
     in kernel memory, and on other systems it is an offset from the beginning
     of the `struct user'.

     As a practical matter, we don't know where the registers actually are,
     so we have to pass the whole area to GDB.  We encode the value of u_ar0
     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
     of the section to -u_ar0).  GDB uses this info to locate the regs,
     using minor trickery to get around the offset-or-absolute-addr problem.  */

	210	There are two tricks with this, though. One is that the rest of the

	212	from *u_ar0. The other is that u_ar0 is sometimes an absolute address

	217	so we have to pass the whole area to GDB. We encode the value of u_ar0
	218	by setting the .regs section up so that its virtual memory address
	219	0 is at the place pointed to by u_ar0 (by setting the vma of the start
	220	of the section to -u_ar0). GDB uses this info to locate the regs,
5bff4f56	221	using minor trickery to get around the offset-or-absolute-addr problem. */
