Krister Walfridsson <kristerw at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|INVALID |FIXED --- Comment #6 from Krister Walfridsson <kristerw at gcc dot gnu.org> --- That's what I believe I've implemented! But the compiler doesn't see the object here, so we can't reason from the provenance -- we just have a random pointer. And a pointer may have any value. I'd argue we can only assume 16-bit alignment, which is enforced by the load: unsigned short pc = q->c; But you're right that SLP already increased this, which smtgcc should have reported... Anyway, all my confusion seems to come from get_object_alignment being inconsistent in what it returns. I need to take a closer look at it. So I now agree this bug report being invalid. :)
