[PATCH] gdb: tests/monitor: set remotetimeout to gdb_load_timeout for remote targets

[Mike Frysinger]

From: Jie Zhang <jie.zhang@analog.com>

Rather than relying on the default remotetimeout value (which might be too
small for some slower devices), use the existing gdb_load_timeout config
option to set it.

No one seems to be comfortable looking at this, so I took a look.
I think the idea makes sense.

Is there a specific reason you already know about that made you
change the remotetimeout only when the target is remote? If there is,
I think it'd be nice to add a comment to that effect. If it's just
because we don't expect the timeout to have any effect in the non-
remote case, then I guess we can leave it like that. But I'm not
to certain about that. I would consider the idea of making things
simpler by just setting the timeout everytime, since this part of
the code will always result in a "load" command being used.

> +proc get_remotetimeout { } {

This function needs a comment describing what it does. Same for
set_remotetimeout.

> +    send_gdb "show remotetimeout\n"
> +    gdb_expect {

Can you use gdb_test_multiple instead?

> +    # Pick the default that gdb uses
> +    return 300

I think we should at least get a warning when that happens, because
it means that the regexp in the check before failed to match.
If we don't have some kind of visual cue, I think it'll be easy
to not notice that something changed, and the function is now
returning a default value, rather than the real timeout at that
time...

> +    send_gdb "set remotetimeout $timeout\n";
> +    gdb_expect {

Same, can we use gdb_test_multiple?

I think it makes no sense to change remotetimeout for non-remote case so 
I added that conditional. I would like to leave it like that since I 
think the code looks clearer in this way. If we take it away, the code 
is simpler, but someone looking at the code might wonder why set 
remotetimeout for non-remote target.

UUIC, that would add something like "PASS: show remotetimeout"
to every test.  Is that wanted?  I was under the impression that
was the reason we didn't use gdb_test_multiple for infrustructure
setup within gdb.exp.

i think that's only if the expect code passed to it calls `pass`.
when i ran it, i didnt see any "PASS: show remotetimeout" ... while, i
did test with gdb-6.6, i dont think this func has changed.

Do you have to use send_gdb/gdb_expect in this file, or can you use
gdb_test, or gdb_test_multiple?

Watch out for stray semicolon at the end of a few statements. Eg:

> +             send_gdb "set remotetimeout $oldremotetimeout\n";
                                                               ^^^

yes, your work on the gnICE/gnICE+ means the slow loading is a thing of the 
past, but i think your changes here are reasonable and address a real problem
