Carl E. Love bdd78711b4 Fix for gdb.base/pc-fp.exp.
It is my understanding that GDB used to require each architecture to
define a Frame Pointer (fp).  However, this functionality was deprecated
some time ago so the call to setup the fp_reg was changed to deprecated
(set_gdbarch_deprecated_fp_regnum).  It should have been removed from the
Power code.

That said, the code "set_gdbarch_deprecated_fp_regnum
(gdbarch, PPC_R0_REGNUM + 1);" sets up register r1 as the frame pointer.
Register r1 is no longer used to hold the frame pointer on Power.  By
removing the fp definition for Power in GDB, it causes GDB to fall back
to the call get_frame_base_address (frame) which returns the correct value
depending on the specific senario but most of the time is the DWARF
canonical frame address.

	* rs6000-tdep.c (rs6000_gdbarch_init): Remove call
        set_gdbarch_deprecated_fp_regnum() from initialization function.

		   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.
