<dl><dt><code>set rstack_high_address </code><var>address</var><dd>On AMD 29000 family processors, registers are saved in a separate
<dfn>register stack</dfn>.  There is no way for <span class="sc">gdb</span> to determine the
extent of this stack.  Normally, <span class="sc">gdb</span> just assumes that the
stack is &ldquo;large enough&rdquo;.  This may result in <span class="sc">gdb</span> referencing
memory locations that do not exist.  If necessary, you can get around
this problem by specifying the ending address of the register stack with
the <code>set rstack_high_address</code> command.  The argument should be an
address, which you probably want to precede with &lsquo;<samp><span class="samp">0x</span></samp>&rsquo; to specify in
hexadecimal.

processors.
