* fwprop.c: New file.
* Makefile.in: Add fwprop.o.
* tree-pass.h (pass_rtl_fwprop, pass_rtl_fwprop_with_addr): New.
* passes.c (init_optimization_passes): Schedule forward propagation.
* rtlanal.c (loc_mentioned_in_p): Support NULL value of the second
parameter.
* timevar.def (TV_FWPROP): New.
* common.opt (-fforward-propagate): New.
* opts.c (decode_options): Enable forward propagation at -O2.
* gcse.c (one_cprop_pass): Do not run local cprop unless touching jumps.
* cse.c (fold_rtx_subreg, fold_rtx_mem, fold_rtx_mem_1, find_best_addr,
canon_for_address, table_size): Remove.
(new_basic_block, insert, remove_from_table): Remove references to
table_size.
(fold_rtx): Process SUBREGs and MEMs with equiv_constant, make
simplification loop more straightforward by not calling fold_rtx
recursively.
(equiv_constant): Move here a small part of fold_rtx_subreg,
do not call fold_rtx. Call avoid_constant_pool_reference
to process MEMs.
* recog.c (canonicalize_change_group): New.
* recog.h (canonicalize_change_group): New.
* doc/invoke.texi (Optimization Options): Document fwprop.
