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