From 110907bae1699e61455334bab40c161ddfc4141d Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Fri, 7 Sep 2018 18:54:49 -0700 Subject: systemc: Mostly implememt sc_simcontext. Since we don't track the current process using the sc_curr_proc_handle structure, we keep one around just to return from the appropriate accessor, and set its values when it's requested. If the object is kept around, those values won't change to track changing processes. From what I see, none of the tests rely on the value tracking the process beyond the callsight.
