--- Comment #12 from Richard Guenther <rguenth at gcc dot gnu.org> 2012-01-16 14:01:18 UTC --- Since 4.6 "For the middle-end the case to char* is not useless, ..." is no longer true. /* We rely on TER to compute accurate alignment information. */ if (!(optimize && flag_tree_ter)) return 0; was also fixed in a conservative way (we do not assume any alignment for that long long * argument). There is a duplicate PR for this, PR43814, I suppose the original PPC testcases still fail.
