  18 # GDB support routines for a board using the MIPS remote debugging
  19 # protocol.  These are actually pretty generic.
  20
  21 # DejaGnu currently assumes that debugging is being done over the main
  22 # console port.  It would probably be more convenient for people using
  23 # IDT boards to permit the debugging port and the connected port to be
  24 # different, since an IDT board has two ports.  This would require
  25 # extending some of the tests in a fashion similar to that done for
  26 # VxWorks, because the test output would appear on the other port,
  27 # rather than being displayed by gdb.
