| <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 “large enough”. 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 ‘<samp><span class="samp">0x</span></samp>’ to specify in |
| hexadecimal. |
