Patrick Palka b5fca6d728 Be lazy about refreshing the windows in tui_show_frame_info (PR tui/13378)
tui_show_frame_info is responsible for updating the visible windows
following a change in frame information (that being the currently
selected frame, PC, line number, etc).  Currently it always redraws and
refreshes each window even if frame information has not changed.  This
behavior is inefficient and helps contribute to the occassional
flickering of the TUI as described in the mentioned PR.

This patch makes tui_show_frame_info refresh the windows only if frame
information has changed.  Determining whether frame information has
changed is done indirectly by determining whether the locator has
changed.  This approach is convenient and yet sensible because the
locator contains all the relevant info we need to check anyway: the
current PC, the line number, the name of the executable and the name of
the current function.  Probably only the PC is really necessary to
check, but it doesn't hurt to check every field.

Effectively, with this patch, consecutive calls to select_frame with the
same frame/PC no longer cause TUI's frame information to be updated
multiple times.

gdb/ChangeLog:

	PR tui/13378
	* tui/tui-stack.c (tui_set_locator_info): Change prototype to
	return an int instead of void.  Return whether the locator
	window has changed.
	(tui_show_frame_info): If the locator info has not changed, then
	bail out early to avoid refreshing the windows.

README

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
