From 08203824c0dcaaab1c1de438d2ecb2995b99544b Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 20 Mar 2019 14:57:56 -0700 Subject: tools/memory-model: Split runlitmus.sh out of checklitmus.sh This commit prepares for adding --hw capability to github litmus-test scripts by splitting runlitmus.sh (which simply runs the verification) out of checklitmus.sh (which also judges the results).
