If so, it needs to punt on anything that uses something more than once.
So, alg_add_factor and alg_sub_factor are always bad (so return NULL),
because they do use accumulator both in the PLUS/MINUS and LSHIFT.
alg_add_t2_m/alg_sub_t2_m/alg_shift if synth_shift_p
and alg.log[i], all in addition to what it has been doing before.
