Hi Richard,

2006-04-05 Richard Guenther <rguenther@suse.de>

	PR middle-end/26898
	* fold-const.c (fold_comparison): Fold signed comparisons
	of the form X +- C1 CMP Y +- C2.

	* gcc.dg/torture/pr26898-1.c: New testcase.
	* gcc.dg/torture/pr26898-2.c: Likewise.

This patch is OK, although probably not suitable for 4.2.

Attachment: smime.p7s
Description: S/MIME cryptographic signature
