* module/language/cps/specialize-numbers.scm (sigbits-ref): New helper. (invert-graph*): New helper. (compute-significant-bits): When visiting a term changes computed needed-bits for one of its definitions, we need to revisit the variables that contributed to its result (the uses), because they might need more bits as well. Previously we were doing this by enqueueing predecessors to the term, which worked if the uses were defined in predecessors, or if all defining terms were already in the worklist, which is the case without loops. But with loops, when revisiting a term, you could see that it causes sigbits to change, enqueue its predecessors, but then the predecessors don't change anything and the fixpoint stops before reaching the definitions of the variables we need. So instead we compute the use-def graph and enqueue defs directly. |
