expr.h (canonicalize_condition, [...]): Add an int argument.
* expr.h (canonicalize_condition, get_condition): Add an int argument. * gcse.c (fis_get_condition): Reimplement using get_condition, leaving it to check whether the condition is still valid at the jump insn. * ifcvt.c (noce_get_condition): Likewise. (noce_get_alt_condition): Update call to canonicalize_condition. * loop-iv.c (simplify_using_initial_values): Update call to get_condition. Remove FIXME. (check_simple_exit): Update call to get_condition. * loop-unswitch.c (may_unswitch_on): Likewise. * loop.c (check_dbra_loop): Likewise. (canonicalize_condition, get_condition): Add an argument to say whether the condition must still be valid at INSN. (get_condition_for_loop): Update call to get_condition. Require that the condition be valid at INSN. * predict.c (estimate_probability): Update call to get_condition. Remove unused earliest parameter. (expected_value_to_br_prob): Update call to canonicalize_condition. From-SVN: r85218
