For structures, not array elements or stack objects. Does gcc now get aligned correct as an attribute on a stack object ?
I think m68k stack layout still guarantees 4-byte-alignment, no?
Still doesn't answer the rather more important question - why not just stick a NULL on the end instead of all the nutty hacks ?
You still do need one bit for the discontiguous case, so it's not like you can avoid the hacks anyway (unless you just blow up the structure entirely) and make it a separate member). So once you have that bit+pointer, using a separate NULL entry isn't exactly prettier. Especially as we actally want to see the difference between "end-of-allocation" and "not yet filled in", so you shouldn't use NULL anyway, you should probably use something like "all-ones".
