If you need this to fix the regression, I think it's fine to merge
the shared lib/*.c files for for 7.4 along with whatever you need on
top. I suspect though based on Sasha's patch, the only thing we
actually need is to stop exporting the floating point functions
so the types don't leak into btf. If you can verify that this
is the case, I would do the full conversion for both nios2
and arc in 7.5.
