emit-rtl.c (remove_unncessary_notes): Remove notes for empty blocks.
* emit-rtl.c (remove_unncessary_notes): Remove notes for empty
blocks.
* final.c (next_block_index): Remove.
(max_block_depth): Likewise.
(pending_blocks): Likewise.
(init_final): Don't initialize them.
(final_start_function): Don't set next_block_index. Set up
BLOCK_NUMBER.
(final_scan_insn): Use BLOCK_NUMBER, not next_block_index.
