re PR rtl-optimization/10914 (unswitch loops does not work on powerpc)
2003-09-12 Zdenek Dvorak <rakdver@atrey.karlin.mff.cuni.cz> PR optimization/10914 * expr.h (get_condition, canonicalize_condition): Declaration changed. * cfgloopanal.c (simple_loop_exit_p): Add parameter to a get_condition and canonicalize_condition calls. * gcse.c (fis_get_condition, delete_null_pointer_checks_1, delete_null_pointer_checks): Ditto. * ifcvt.c (noce_get_alt_condition, noce_get_condition): Ditto. * predict.c (estimate_probability, expected_value_to_br_prob): Ditto. * loop.c (check_dbra_loop, get_condition_for_loop): Ditto. (canonicalize_condition, get_condition): Allow to return comparisons of cc mode registers. * loop-unswitch.c (may_unswitch_on_p, unswitch_single_loop): Allow cc mode registers comparison in condition.
