tree-cfg.c (verify_expr): COND_EXPRs can have any integral typed condition.
2007-07-20 Richard Guenther <rguenther@suse.de>
* tree-cfg.c (verify_expr): COND_EXPRs can have any
integral typed condition.
* tree-ssa.c (useless_type_conversion_p): Do not preserve
booleanness. Only preserve conversions from a non-base
type to a base type, not in general between types with
different TYPE_MIN_VALUE or TYPE_MAX_VALUE.
* tree.def (COND_EXPR): Document that the condition
can be of any integral type.
