Andrew Burgess 391c90eea5 gdb: make use of SCOPE_EXIT to manage thread executing state
While working on another patch relating to how GDB manages threads
executing and resumed state, I spotted the following code in
record-btrace.c:

  executing = tp->executing ();
  set_executing (proc_target, inferior_ptid, false);

  id = null_frame_id;
  try
    {
      id = get_frame_id (get_current_frame ());
    }
  catch (const gdb_exception &except)
    {
      /* Restore the previous execution state.  */
      set_executing (proc_target, inferior_ptid, executing);

      throw;
    }

  /* Restore the previous execution state.  */
  set_executing (proc_target, inferior_ptid, executing);

  return id;

I notice that we only catch the exception so we can call
set_executing, and this is the same call to set_executing that we need
to perform in the non-exception return path.

This would be much cleaner if we could use SCOPE_EXIT to avoid the
try/catch, so lets do that.

While cleaning this up, I also applied a similar patch to
record-full.c, though there's no try/catch in that case, but using
SCOPE_EXIT makes the code safe if, in the future, we do start throwing
exceptions.

There should be no user visible changes after this commit.

		   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.
