re PR middle-end/31029 (Fold does not fold C - a == a)
2009-03-31 Richard Guenther <rguenther@suse.de>
PR middle-end/31029
* fold-const.c (fold_binary): Fold X +- Y CMP X to Y CMP 0 for
equality comparisons. Fold C - X CMP X if C % 2 == 1.
* gcc.dg/fold-compare-4.c: New testcase.
* gcc.dg/fold-compare-5.c: Likewise.
