OK, previously I thought if we can claim GEP and LEP (and the area between) as one special function entry (area) in documentation, but admittedly it's too tricky. Adding one separated command line option now just for one potential use case in future seems not a good idea. Following the previous proposal, I just posted v4 at: https://gcc.gnu.org/pipermail/gcc-patches/2022-August/600277.html BR, Kewen
