--- Comment #2 from Marc Glisse <glisse at gcc dot gnu.org> ---
Ah, I didn't test with --enable-ckecking=rtl.

We could split the "maybe" part of the warning and downgrade it to Wextra, but
I'd rather keep it at least in Wall, which means we need to change the
loop-unroll code anyway.

The code is not easy to understand. For instance, I don't see where n_loc can
be set to any value other than 1? That would make it easy to simplify this
loop...
