we won't use SImode to access A::j because we're setting maxbits to 28.
No, maxbits is actually 32, because we include padding. So it's correct
in this case.
What padding? bitregion_end-bitregion_start+1 will be 32, but in
get_best_mode I see
+ maxbits = bitregion_end - bitpos + 1;
which is 28. No?
Incidentally, I would expect _end to be one past the end rather than the
index of the last element, but perhaps I just expect that because C++
iterators work that way.
