------- Additional Comments From pinskia at gcc dot gnu dot org 2005-03-04 06:26 ------- Reopening as this patch had to reverted as it caused a bootstrap failure on ppc-darwin. I think there really is a latent bug with -1 - A being converted to ~A and then ~A is constant folded to -1 but it contains a TREE_OVERFLOW bit turned on which it did not with -1 - A before. (there might be some unsignedness going on that I don't know about).
