re PR middle-end/30905 (Fails to cross-jump)
2008-01-11 Steven Bosscher <stevenb.gcc@gmail.com>
PR rtl-optimization/30905
* cfgcleanup.c: Include dce.h
(crossjumps_occured): New global variable.
(try_crossjump_bb): Exit loop after finding a fallthru edge.
If something changed, set crossjumps_occured to true.
(try_optimize_cfg): Clear crossjumps_occured at the beginning.
Don't add/remove fake edges to exit here...
(cleanup_cfg): ...but do it here, when crossjumping.
Run a fast DCE when successful crossjumps occured in the latest
iteration of try_optimize_cfg.
