Ken Raeburn cb92366029 * Revamped multiply support for MIPS chips.
* mips.c (extend_operator): New function.
        (highpart_shift_operator): Likewise.
        * mips.h: Declare new functions.
        (PREDICATE_CODES): Add support for new predicates.
        * mips.md (mulsi3 expander): Simplify.
        (mulsi_mult3): Add another constraint alternative.  Support
        3 operand multiply instructions as found on various mips
        parts.
        (mulsi3_r4650): Delete pattern, now handled by mulsi_mult3.
        (mul_acc_si): New pattern and associated splitters.
        (mulsidi3 expander): Rework to use mulsidi3_64bit and
        mulsidi3_internal.
        (umulsidi3): New expander.
        (mulsidi3_internal): Accept either sign or zero extended
        operands and generate code as appropriate appropriately.
        (mulsidi3_64bit): Similarly.
        (smulsi3_highpart): Turn into an expander and generate code
        to match new patterns.
        (umulsi3_highpart): Likewise.
        (xmulsi3_highpart_internal): New pattern.
        (maddi patterns): Delete.  Replace with:
        (mul_acc_di, mul-acc_64bit_di): New patterns.

		   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.
