Kevin Buettner 6d45194248 Use 16-bit integer type for rl78 register pairs.
This patch changes rl78-tdep.c so that a 16-bit type is used for
register pairs instead of a pointer type as was previously the case.
This will cause these register pairs to be displayed as integers
instead of as a data address with a 0xf0000 ORed in.

E.g. registers ax, bc, de, and hl might now be displayed like this:

    (gdb) info registers ax bc de hl
    ax             0x6      6
    bc             0x0      0
    de             0x10c3   4291
    hl             0x108d   423

Whereas, before, they were displayed as follows:

    (gdb) info registers ax bc de hl
    ax             0xf0006  0xf0006
    bc             0xf0000  0xf0000
    de             0xf10c3  0xf10c3
    hl             0xf108d  0xf108d

These pairs are 16 bit quantities and should be displayed as such.
This change also affects the way that the banked register pairs are
displayed.  Within GDB, the banked register pairs are named bank0_rp0,
bank0_rp1, .., bank3_rp2, bank3_rp3.

However, these register pairs need to be used as addresses in DWARF
expressions.  I have added 16 pseudo registers corresponding to banked
register pairs.  These new pseudo registers are all hidden from the
user and have a pointer type.  Values from these registers are
intended to be used in DWARF expressions.  Therefore,
rl78_dwarf_reg_to_regnum() has been adjusted to return these new
pseudo register numbers.

I had a much simpler patch which only changed the types, but it showed
a number of regressions due to integer values from the banked register
pairs being used as part of an address expression.  This current patch
shows no regressions and now displays values of register pairs
correctly.

		   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.
