To: gdb-patches
Ref: https://sourceware.org/ml/gdb/2015-07/msg00011.html
All of these targets use gdb/monitor.c, which has bit rotted
years ago (I'd guess around ~6), and nobody seems to
have noticed:
| target | source |
|----------------+----------------------|
| target dbug | gdb/dbug-rom.c |
| target picobug | gdb/microblaze-rom.c |
| target dink32 | gdb/dink32-rom.c |
| target m32r | gdb/m32r-rom.c |
| target mon2000 | gdb/m32r-rom.c |
| target ppcbug | gdb/ppcbug-rom.c |
This deletes them, along with finally removing monitor.c.
A manual update will be done separately.

- This module talks to a debug monitor called 'MONITOR', which

- (or possibly TELNET) stream to a terminal multiplexor,
- which in turn talks to the target board. */

- any actual 64-bit targets with ROM monitors that use this code,
- it's not an issue right now. -sts 4/18/96 */

-/* This structure describes the strings necessary to give small command
- sequences to the monitor, and parse the response.
-
- CMD is the actual command typed at the monitor. Usually this has
- embedded sequences ala printf, which are substituted with the
- arguments appropriate to that type of command. Ie: to examine a
- register, we substitute the register name for the first arg. To
- modify memory, we substitute the memory location and the new
- contents for the first and second args, etc...
-
- RESP_DELIM used to home in on the response string, and is used to
- disambiguate the answer within the pile of text returned by the
- monitor. This should be a unique string that immediately precedes
- the answer. Ie: if your monitor prints out `PC: 00000001= ' in
- response to asking for the PC, you should use `: ' as the
- RESP_DELIM. RESP_DELIM may be NULL if the res- ponse is going to
- be ignored, or has no particular leading text.
-
- TERM is the string that the monitor outputs to indicate that it is
- idle, and waiting for input. This is usually a prompt of some
- sort. In the previous example, it would be `= '. It is important
- that TERM really means that the monitor is idle, otherwise GDB may
- try to type at it when it isn't ready for input. This is a problem
- because many monitors cannot deal with type-ahead. TERM may be
- NULL if the normal prompt is output.
-
- TERM_CMD is used to quit out of the subcommand mode and get back to
- the main prompt. TERM_CMD may be NULL if it isn't necessary. It
- will also be ignored if TERM is NULL. */
