From: Gabe Black Date: Sun, 7 Oct 2018 02:00:56 +0000 (-0700) Subject: systemc: Refactor reporting to prep for int based messages. X-Git-Tag: v19.0.0.0~1507 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7eb6ad4aaa3afb8a5625a4515cbcfd141d5ce45b;p=gem5.git systemc: Refactor reporting to prep for int based messages. There's a deprecated reporting mechanism based on integer message ids, and the reporting mechanism needs to be refactored a bit to make it easier to support. Some bookkeeping data structures were moved out to somewhere they can be accessed by other code, obviating the non-standard get_handler function.
