--- 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...
