From ed8b7f2e310ce8828cd98caa8eb895d99da6f7ef Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Fri, 5 Jan 2018 15:40:47 -0800 Subject: cpu: Add a NotAnInst flag to the BaseDynInst class. This flag means that the instruction isn't an actual instruction, it's just a placeholder to carry a fault down a pipeline, for instance.
