I am not sure "gc" is correct word here. We do not mark non-alloc sections as reachable/unreachable to

do gc for them I think. Because they point to something, but not something points to them.

It also looks not possible to have debug section that points only on dead alloc sections.

At least until you have any .text alive.

Anyways that discussion and possible improvements for above is already a bit away from area of that patch.

Do you think details above is a stopper for landing this one ?
