From d4640ffe33ee3c1377582d69795a637452442409 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Sun, 5 Apr 2020 05:31:08 -0700 Subject: [PATCH] util: Expose the "sum" m5 op in the m5 utility. This is just for testing purposes, and can be used to sanity check that m5 ops work when running a simulation.
