- Subject: [patch, rfa:doco] Add set/show remote hardware-breakpoint/watchpoint-limit
Hello,
This follows up a number of previous posts. It adds the commands:
set remote hardware-breakpoint-limit
set remote hardware-watchpoint-limit
show remote hardware-breakpoint-limit
show remote hardware-watchpoint-limit
A limit of -1 is infinite, zero is zero. It also uses the i18n friendly
add_setshow_cmd().
Eli, how is the doco?

* remote.c (_initialize_remote): Add commands "set/show remote
hardware-watchpoint-limit" and "set/show remote
hardware-breakpoint-limit".
(remote_hw_watchpoint_limit): Initialize to -1.
(remote_hw_breakpoint_limit): Ditto.
(remote_check_watch_resources): Treat a limit of -1 as unlimited.

* gdb.texinfo (Set Breaks): Add cross reference to "set remote
hardware-breakpoint-limit".
(Set Watchpoints): Add cross reference to "set remote
hardware-watchpoint-limit".
(Remote configuration options): New section.
