re PR tree-optimization/25148 (compare_values assumes that CST in a + CST (and a - CST) is always postive)
2006-04-27 Richard Guenther <rguenther@suse.de>
PR tree-optimization/25148
* tree-vrp.c (compare_values): Remove code dealing with
comparisons against type min/max value. Honour overflow
and negative constants in code dealing with comparisons
of plus and minus expressions.
(value_inside_range): Use fold_binary with LE_EXPR and
GE_EXPR rather than compare_values.
