Merge pull request #5615 from rocallahan/remove-used-signals-updates

nella a75e0b2e92 opt_dff minor cleanup, added tests for comp var. 2026-01-26 14:24:01 +01:00
Robert O'Callahan 32e96605d4 Don't update `used_signals` for retained wires in `rmunused_module_signals`. 
These updates should not be necessary. In fact, if they were necessary, this code
would be buggy, because the results would depend on the order in which wires are traversed:
If wire A is retained, which causes an update to `used_signals`, which then causes wire B
to be retained when it otherwise wouldn't be, then we would get different results depending
on whether A is visited before B.

These updates will also make it difficult to process these wires in parallel.

Robert O'Callahan 7d53d64a47 Make the call to `compare_signals()` easier to read. 
The negation here is confusing. The intent of the code is "if `s1` is preferred
over `s2` as the canonical `SigBit` for this signal, make `s1` the canonical `SigBit`
in `assign_map`", so write the code that way instead of "if `s2` is not preferred
over `s1` ...".

This doesn't change any behavior now that `compare_signals()` is a total order,
i.e. `s1` is preferred over `s2`, `s2` is preferred over `s1`, or `s1` and `s2` are equal.
Now, when `s1` and `s2` are equal, we don't call `assign_map.add(s1)`, but that's
already a noop in that case.
 2026-01-24 02:01:05 +00:00
Robert O'Callahan 2468b391bf Make `compare_signals` produce a total order. 
Currently when `s1` and `s2` are different bits of the same wire,
it is possible for both `compare_signals(s1, s2)` and `compare_signals(s2, s1)` to
return false. This means the calling code will call `assign_map.add()` for
both `s1` and `s2`, which doesn't make much sense --- one of `s1` or `s2`
should be consistently preferred.

So fix that by preferring the `SigBit` with the smaller bit offset.
