Richard Henderson 45f97e2e08 loop.h (struct induction): Add no_const_addval.
* loop.h (struct induction): Add no_const_addval.
        * loop.c (the_movables, reg_address_cost): New variables.
        (init_loop): Init reg_address_cost.
        (loop_optimize): Call end_alias_analysis.
        (scan_loop): Init the_movables.
        (record_giv): Init induction->no_const_addval.
        (basic_induction_var) [PLUS]: Use rtx_equal_p instead of ==.
        [REG]: Rearrange loop search test to catch more cases.
        (general_induction_var): Return success not benefit; take an extra
        argument for that.  Change all callers.
        (simplify_giv_expr) [PLUS]: Always combine invariants.  Use sge_plus.
        [MULT]: Use rtx_equal_p instead of ==.  Combine simple invariants.
        [default]: Search the_movables for additional combinations.
        (sge_plus_constant, sge_plus): New functions.
        (express_from_1): New function.
        (express_from): Always define.  Rewrite using express_from_1.
        (combine_givs_p): Handle more cases.  Ignore address cost.
        (cmp_combine_givs_stats): New function.
        (combine_givs_used_once, combine_givs_benefit_from): New functions.
        (combine_givs): Rewrite to do best-fit combination.
        * fold-const.c (operand_equal_p): Handle RTL_EXPR.
        (fold): Do a complete (A*C)+(B*C) association check.

		   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.
