Author: rguenth Date: Fri Jan 11 14:55:34 2008 New Revision: 131468 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=131468 Log: 2008-01-11 Steven Bosscher <[EMAIL PROTECTED]> 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.
