| 2017-12-20 | Fix bug in ConstProp where module dependency edges were dropped (#696) | Jack Koenig | |
| This resulted in parent modules sometimes being constant proppagated before a child module. If the child module has a constant driving one of its outputs, the parent module would thus not see the constant. This resulted in strange unstable constant propagation behavior where sometimes constant outputs would not propagate. Also add test illustrating why this occurs with uses of InstanceGraph | |||
