[patch, rfa:doco] Add set/show remote hardware-breakpoint/watchpoint-limit

[patch, rfa:doco] Add set/show remote hardware-breakpoint/watchpoint-limit

[Andrew Cagney]

[-- Attachment #1: Type: text/plain, Size: 355 bytes --]

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?

Andrew

	* 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.

Okay with me, but please see that the references to @anchor's look well
in the printed copy.

(ok)

Meta question, is there a shorthand way of doing this:

@kindex command
@anchor command
@index command

?  Perhaphs a custom GDB @macro?

I don't think so.

I'd recommend against using @macro unless absolutely necessary.
Texinfo macros give you a lot of trouble when you TeX the manual.
