Andrew Burgess 6dff2a6ffe gdb/arm: move fetch of arm_gdbarch_tdep to a more inner scope
This is a small refactor to resolve an issue before it becomes a
problem in a later commit.

Move the fetching of an arm_gdbarch_tdep into a more inner scope
within two functions in arm-tdep.c.

The problem with the current code is that the functions in question
are used as the callbacks for two set/show parameters.  These set/show
parameters are available no matter the current architecture, but are
really about controlling an ARM architecture specific setting.  And
so, if I build GDB for all targets on an x86-64/GNU-Linux system, I
can still do this:

  (gdb) show arm fpu
  (gdb) show arm abi

After these calls we end up in show_fp_model and arm_show_abi
respectively, where we unconditionally do this:

  arm_gdbarch_tdep *tdep
    = (arm_gdbarch_tdep *) gdbarch_tdep (target_gdbarch ());

However, the gdbarch_tdep() result will only be a arm_gdbarch_tdep if
the current architecture is ARM, otherwise the result will actually be
of some other type.

This isn't actually a problem, as in both cases the use of tdep is
guarded by a later check that the gdbarch architecture is
bfd_arch_arm.

This commit just moves the call to gdbarch_tdep() after the
architecture check.

In a later commit gdbarch_tdep() will be able to spot when we are
casting the result to the wrong type, and this function will trigger
assertion failures if things are not fixed.

There should be not 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.
