As I mentioned in another reply, we should not be using packed. Packed has other implications, which makes it use byte-at-a-time accesses for all parts of a structure when you tag it with 'packed'. GCC doesn't try to be clever and see that actually such accesses are safe. If plain "__long_aligned" works and, since you're tagging it to the structure definition, it only specifies a minimum-alignment, then I'm fine with using that to fix this. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
