16 | # The doco makes reference to built-in registers -- $pc and $fp. If |
| 17 | # the ISA contains registers by that name then they should be | |
| 18 | # displayed. If the ISA contains registers identified as being | |
| 19 | # equivalent, but have different names, then GDB will provide these as | |
| 20 | # aliases. If the ISA doesn't provide any equivalent registers, then | |
| 21 | # GDB will provide registers that map onto the frame's PC and FP. | |
