Faraz Shahbazker 387e762476 Add macro expansions for ADD, SUB, DADD and DSUB for MIPS r6
Release 6 of the MIPS architecture does not have an ADDI instruction.
ADD/SUB instructions with immediate operands can be expanded to load
and immediate value and then perform the operation.

gas/
	* config/tc-mips.c (macro) <M_ADD_I, M_SUB_I, M_DADD_I, M_DSUB_I>:
	Add expansions for MIPS r6.
	* testsuite/gas/mips/add.s: Enable tests for R6.
	* testsuite/gas/mips/daddi.s: Annotate to test DADD for R6.
	* testsuite/gas/mips/mipsr6@add.d: Likewise.
	* gas/testsuite/gas/mips/mipsr6@dadd.d: New test.
	* gas/testsuite/gas/mips/mips.exp: Run the new test.

opcodes/
        * mips-opc.c (mips_opcodes): Enable ADD, SUB, DADD and DSUB
	macros for R6.

		   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

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
