  22      <br><dt><code>set rstack_high_address </code><var>address</var><code></code>
  23      <dd>On AMD 29000 family processors, registers are saved in a separate
  24 <dfn>register stack</dfn>.  There is no way for GDB to determine the
  25 extent of this stack.  Normally, GDB just assumes that the
  26 stack is "large enough".  This may result in GDB referencing
  27 memory locations that do not exist.  If necessary, you can get around
  28 this problem by specifying the ending address of the register stack with
  29 the <code>set rstack_high_address</code> command.  The argument should be an
  30 address, which you probably want to precede with <code>0x</code> to specify in
  31 hexadecimal.

  35 processors.
