cxxrtl: don't emit invalid code on unconnected outputs. #4417

Closed kivikakk closed 3 months ago

kivikakk commented 4 months ago

Unconnected sync outputs cause dump_cell_sync to emit an invalid assignment in the instantiating module, namely value<0>() = …;.

Ensure the LHS is not empty before emitting.
