--- Comment #17 from Nathan Froyd <froydnj at gcc dot gnu.org> --- (In reply to Richard Biener from comment #15) > Instead aligned the string. This is kind of unfortunate, as the motivating testcase was something more like: ... static const char string[] = "Private"; unsigned int priv, riva, ivat, vate; memcpy(&priv, &string[0], sizeof(priv)); memcpy(&riva, &string[1], sizeof(riva)) memcpy(&ivat, &string[2], sizeof(ivat)); memcpy(&vate, &string[3], sizeof(vate)); /* proceed to use priv, riva, ivate, vate for comparisons */ So on strict-align targets, even if the source string was aligned (and that has to be by user-declaration?) we wouldn't catch the latter three?
