Carl Love a0a97b8cac rs6000, Fix test gdb.base/store.exp
The test currently fails for IEEE 128-bit floating point types.  PowerPC
supports the IBM double 128-bit floating point format and IEEE 128-bit
format.  The IBM double 128-bit floating point format uses two 64-bit
floating point registers to store the 128-bit value.  The IEEE 128-bit
floating point format stores the value in a single 128-bit vector-scalar
register (vsr).

The various floating point values, 32-bit float, 64-bit double, IBM double
128-bit float and IEEE 128-bit floating point numbers are all mapped to the
DWARF fpr numbers.  The issue is the IEEE 128-bit floating point values are
actually stored in a vsr not the fprs.  This patch changes the register
mapping for the vsrs from the fpr to the vsr registers so the value is
properly accessed by GDB.  The functions rs6000_linux_register_to_value,
rs6000_linux_value_to_register, rs6000_linux_value_from_register check if
the value is an IEEE 128-bit floating point value and adjust the register
number as needed.  The test in function rs6000_convert_register_p is fixed
so it is only true for floating point values.

This patch fixes three regression tests in gdb.base/store.exp.

The patch has been tested on Power 8 LE/BE, Power 9 LE/BE and Power 10 LE
with no regressions.

		   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.
