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