basic-block.h (basic_block): Add eh_beg, eh_end.
* basic-block.h (basic_block): Add eh_beg, eh_end.
* flow.c (entry_exit_blocks): Update.
(find_basic_blocks): Don't allocate bb_eh_end, or pass it around.
Call new functions.
(find_basic_blocks_1): Don't record eh_list at each bb. Use
lists.c functions to allocate insn lists.
(make_edges): Use eh_beg+eh_end, not the lists. Split out EH
edge creation ...
(make_eh_edge): ... here. New.
(move_stray_eh_region_notes): New.
(record_active_eh_regions): New.
(delete_unreachable_blocks): Split out block merging ...
(try_merge_blocks): ... here. New.
(merge_blocks_move_predecessor_nojumps): Remove edge arg.
Dump debugging data.
(merge_blocks_move_successor_nojumps): Likewise.
