Robert O'Callahan e9aacd8a05 Move `OptMerge` cell filtering logic to happen while building the cell vector.
This code is quite confusing because there are two "is the cell known" filters
applied, one while building the cell vector and one after building the cell
vector, and they're subtly different. I'm preserving the actual behaviour here
but it looks like there is, or was, a bug here.

Jannis Harder 5f79a6e868 Clean up $buf with 'z inputs, $input_port and $connect cells
This ensures that entering and leaving bufnorm followed by `opt_clean`
is equivalent to just running `opt_clean`.

Also make sure that 'z-$buf cells get techmapped in a compatible way.

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.
