From 8e89366ada0213d45af088945406c82187b5014a Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Thu, 7 Mar 2019 00:46:29 -0800 Subject: sim: Add a getPort function to SimObject. This will retrieve a Port object from a given SimObject (which might not be a MemObject) no matter what flavor of Port it is.
