Emil J. Tywoniak 4dea774171 opt_muxtree: refactor 2025-08-21 12:52:22 +02:00
Robert O'Callahan 8c04e5266c Use commutative hashing instead of expensive allocation and sorting 
For one of our large circuits, this improves the `OptMergePass` runtime
from about 150s to about 130s. It's also simpler code.

Merge pull request #5290 from rocallahan/opt-mux-perf 
Make `OptMuxtreePass` int-indexed vectors into hashtables
 2025-08-20 20:00:26 +02:00
Robert O'Callahan 3f2c4f6f83 Remove redundant construction of `assign_map`. 
We call 'assign_map.set()' below which wipes the `SigMap` and reconstructs it.

This operation is expensive because it scans the whole module. I think it's
better to make heavyweight operations more visible so I'm removing
the less obvious operation.

Robert O'Callahan dd88423334 Make OptMuxtree int-indexed vectors into hashtables 
For one of our large circuits, this reduced the time for an OPT_MUXTREE pass from
169s to 5s.
