From 35bb6ee6790600d29c598ebbf262359341f34e38 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 14 May 2018 16:33:43 -0700 Subject: tools/memory-order: Improve key for SELF and SV The key for "SELF" was missing completely and the key for "SV" was a bit obtuse. This commit therefore adds a key for "SELF" and improves the one for "SV". Reported-by: Paolo Bonzini Signed-off-by: Paul E.
