* sbitmap.c (sbitmap_first_set_bit, sbitmap_last_set_bit): New
function.
* sbitmap.h (sbitmap_first_set_bit, sbitmap_last_set_bit): Declare.
* basic_block.h (FLOW_LOOP_FIRST_BLOCK): New macro.
(FLOW_LOOP_LAST_BLOCK): Likewise.
2000-01-21 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
* basic-block.h (struct loop): New fields 'first' and 'last'.
* flow.c (flow_loops_find): Compute loop->first and loop->last.
(flow_loops_dump): Use loop->first to check for NOTE_INSN_LOOP_BEG
and loop->last to check for NOTE_INSN_LOOP_END.
Fri Jan 28 10:57:58 2000 Jason Eckhardt <jle@cygnus.com>
* predict.c (estimate_probability): Use the new FIRST and LAST fields
of the loop descriptor rather than HEADER and LATCH. Also added
missing break statements as well making some coding style modifications
as suggested by Michael Hayes.
