--- Comment #7 from Siddhesh Poyarekar <siddhesh at gcc dot gnu.org> ---
I've posted a patch:

https://gcc.gnu.org/pipermail/gcc-patches/2022-January/587698.html

which returns the whole size of an object (that's a thing now, since __bos
started handling negative offsets) if the offset is not a constant.  It goe=
s on
top of the dynamic object sizes patchset.

Volatile offsets will need more rework (basically delay the side effects ch=
eck
into tree-object-size), so I'll do that after all of these patches are thro=
ugh.=
