rtl.h (rtx_function): New type.
* rtl.h (rtx_function): New type.
(for_each_rtx): New function.
* rtlanal.c (for_each_rtx): Define it.
* recog.c (change_t): New type.
(change_objects, change_old_codes, change_locs, change_olds):
Replace with ...
(changes): New variable.
(validate_change): Dynamically allocate room for more changes, if
necessary. Uses changes array instead of change_objects, etc.
(apply_change_group): Use changes array instead of
change_objects, etc.
* loop.c (loop_mem_info): New type.
(loop_mems): New variable.
(loop_mems_idx): Likewise.
(looop_mems_allocated): Likewise.
(scan_loop): Remove nregs parameter.
(next_insn_in_loop): New function.
(load_mems_and_recount_loop_regs_set): Likewise.
(load_mems): Likewise.
(insert_loop_mem): Likewise.
(replace_loop_mem): Likewise.
(replace_label): Likewise.
(INSN_IN_RANGE_P): New macro.
(loop_optimize): Don't pass max_reg_num() to scan_loop.
(scan_loop): Remove nregs parameter, compute it after any new
registers are created by load_mems. Use INSN_IN_RANGE_P and
next_insn_in_loop rather than expanding them inline. Call
load_mems to load memory into pseudos, if appropriate.
(prescan_loop): Figure out whether or not there are jumps from the
loop to targets other than the label immediately following the
loop. Call insert_loop_mem to notice all the MEMs used in the
loop, if it could be safe to pull MEMs into REGs for the duration
of the loop.
(strength_reduce): Use next_insn_in_loop. Tweak comments.
