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.
