Hi.
This patch converts loops of bitmap_set_bit/bitmap_clear_bit in to
bitmap_set_range/bitmap_clear_range functions call.
The patch has been bootstrapped on and regression tested on
x86_64-unknown-linux-gnu for c.
OK to install?
* cfgcleanup.c (mark_effect): Use
bitmap_set_range/bitmap_clear_range
instead of loop. Use HARD_REGISTER_NUM_P predicate.
* haifa-sched.c (setup_ref_regs): Ditto.
* caller-save.c (add_used_regs_1): Ditto.
* dse.c (look_for_hardregs): Ditto.
* df-problems.c (df_simulate_one_insn_forwards): Ditto.
* sched-rgn.c (check_live_1): Ditto.
This looks like a reasonable cleanup, but I can't see how this fixes any
kind of bug, so it should be postponed until stage1 reopens. If you could
attach it to the GCC 4.7 pending patches metabug that would help ensure it
doens't get lost.
