The issue is that print_stack_frame always sets the current sal to the
frame's sal. print_frame_info (which print_stack_frame calls to do
most of the work) also sets the last displayed sal, but only if
print_what isn't LOCATION. Now the call in question, from within
thread.c:print_thread_info, does pass in LOCATION as print_what, but
print_stack_frame doesn't have the same check print_frame_info has.
We could consider adding it, but setting these globals depending on
print_what isn't very clean, IMO. What we have is two logically
distinct operations mixed in the same function(s):
#1 - print frame, in the format specified by {print_what,
print_level and print_args}.
#2 - We're displaying a frame to the user, and I want the default
sal to point here, because the program stopped here, or the user
did some context-changing command (up, down, etc.).
So I added a new parameter to print_stack_frame & friends for point
#2, and went through all calls in the tree adjusting as necessary.

This patch fixes the target double-close problem (PR remote/15266),
and in the process removes pop_target entire (PR remote/15256).
The first issue is that pop_target calls target_close. However, it
then calls unpush_target, which also calls target_close. This means
targets must be able to be closed twice. Not only is this strange,
but it also directly contradicts the contract of to_xclose targets.
(We currently have just a single such target, and it is never pushed;
but I plan to add more, and so this latent bug is triggered.)
The second issue is that it seems to me that calling pop_target is
often unsafe. This is what cropped up in 15256, where the remote
target assumed that it could pop_target -- but there was another
target higher on the stack, leading to confusion.
But, it is always just as easy to call unpush_target as it is to call
pop_target; and it is also safer. So, removing pop_target seemed like
an improvement.
Finally, this adds an assertion to target_close to ensure that no
currently-pushed target can be closed.
Built and regtested on x86-64 Fedora 18; both natively and using the
native-gdbserver board file.

While the RSP is largely ASCII based (hence the packet buffer type is
char *), at places we pass around 8-bit binary packets in that buffer.
Functions like hex2bin or remote_escape_output conceptually are
handling binary buffers, so I left them as working with gdb_byte, and
added casts where necessary. Whether these are host bytes or target
bytes is blurry at present, so this is largely a matter of taste.
Switching some of these functions to take "char *" or "void *" would
be equally good.

Currently, several commands take "0" or "-1" to mean "unlimited".
"show" knows when to print "unlimited":
(gdb) show height
Number of lines gdb thinks are in a page is 45.
(gdb) set height 0
(gdb) show height
Number of lines gdb thinks are in a page is unlimited.
However, the user can't herself specify "unlimited" directly:
(gdb) set height unlimited
No symbol table is loaded. Use the "file" command.
(gdb)
This patch addresses that, by adjusting the set handler for all
integer/uinteger/zuinteger_unlimited commands to accept literal
"unlimited". It also installs a completer. Presently, we complete on
symbols by default, and at
<http://sourceware.org/ml/gdb-patches/2013-03/msg00864.html> I've
shown a WIP prototype that tried to keep that half working in these
commands. In the end, it turned out to be more complicated than
justifiable, IMO. It's super rare to want to pass the value of a
variable/symbol in the program to a GDB set/show knob. That'll still
work, it's just that we won't assist with completion anymore. This
patch just sticks with the simple, and completes on "unlimited", and
nothing else. This simplification means that
"set he<tab><tab>"
is all it takes to get to:
"set height unlimited"
The patch then goes through all integer/uinteger/zuinteger_unlimited
commands in the tree, and updates both the online help and the manual
to mention that "unlimited" is accepted in addition to 0/-1. In the
cases where the command had no online help text at all, this adds it.
I've tried to make the texts read in a way that "unlimited" is
suggested before "0" or "-1" is.

Gareth mentions in PR gdb/15275:
"The MI '-gdb-exit' command mi_cmd_gdb_exit() never calls disconnect_tracing()
and therefore exits correctly."
It should, so to get out of tfind mode, as quit may detach instead of
kill, and we don't want to confuse the memory/register accesses
etc. of the detach process. So we should push down the disconnect
tracing bits at least to quit_force. But we can't as is, as that
would swallow the error thrown by answering "no" to:
Trace is running but will stop on detach; detach anyway? (y or n)
So to address that, we split disconnect_tracing in two. One part that
does the query, and another part that does the rest, and we make
quit_force call the latter.
Looking at quit_force, it does several things, some of which are a bit
independent of the others. It first kills/detaches, and then writes
history, and then runs the final cleanups. It seems better to me to
do each of these things even if the previous thing throws. E.g., as
is, if something throws while detaching, then we skip writing history.

This is sort of a continuation of Keith's parse_exp_1 constification
patch. It started out by undoing these bits:
@@ -754,9 +754,12 @@ validate_actionline (char **line, struct
tmp_p = p;
for (loc = t->base.loc; loc; loc = loc->next)
{
- p = tmp_p;
- exp = parse_exp_1 (&p, loc->address,
+ const char *q;
+
+ q = tmp_p;
+ exp = parse_exp_1 (&q, loc->address,
block_for_pc (loc->address), 1);
+ p = (char *) q;
and progressively making more things const upwards, fixing fallout,
rinse repeat, until GDB built again (--enable-targets=all).
That ended up constifying lookup_cmd/add_cmd and (lots of) friends,
and the completers.
I didn't try to constify the command hooks themselves, because I know
upfront there are commands that write to the command string argument,
and I think I managed to stop at a nice non-hacky split point already.
I think the only non-really-super-obvious changes are
tracepoint.c:validate_actionline, and tracepoint.c:trace_dump_actions.
The rest is just mostly about 'char *' => 'const char *', 'char **'=>
'const char **', and the occasional (e.g., deprecated_cmd_warning)
case of 'char **'=> 'const char *', where/when I noticed that nothing
actually cares about the pointer to pointer output.
Tested on x86_64 Fedora 17, native and gdbserver.
