--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
True, but might eat more compile time memory.
Further, the question stands, is what find_base_term returns for a particular
VALUE cacheable for the whole duration between cselib_init and cselib_finish in
each pass, or not?  Would be nice to again do instrumented bootstrap/regtest to
gather data whether it ever differs and how often if it does.
