So, before IPA-CP, foo had:
_10 = BIT_FIELD_REF p, 32, 0;
_11 = _10 507904;
Now, IPA-CP does:
Modification phase of node foo.constprop.0/3
Aggregate replacements: 0[14]=1,

--- Comment #4 from Jakub Jelinek jakub at gcc dot gnu.org ---
Note that likely since r199252 Aggregate replacements: 0[14]=1, 0[8]=0, 0[0]=1
is replaced with just 0[0]=1, still the effect is exactly the same.

--- Comment #5 from Jakub Jelinek jakub at gcc dot gnu.org ---
Ah, the reason why r199252 doesn't fix this is that esra changes o.f0 = 1;
into a MEM_REF, essentially *(char *)o = 1, because the f0 has 8 bits.
So, determine_known_aggregate_parts

As far as I'm concerned, the patch is fine. Thanks for taking care of it.

Well, there is if (*size_p) which should have been if (size_p) obviously,
redoing bootstrap now with that fix.
