| * extract_reduce: Fix segfault on "undriven" inputsRobert Ou2017-09-141-2/+2
| | | | | | | | | | | | | | | | This is easily triggered when un-techmapping if the technology-specific cell library isn't loaded. Outputs of technology-specific cells will be seen as inputs, and nets using those outputs will be seen as undriven. Just ignore these cells because they can't be part of a reduce chain anyways.
