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