-From 11b283092a29a9d402ce05706fd3a85683576218 Mon Sep 17 00:00:00 2001
-From: David Chase <drchase@google.com>
-Date: Tue, 21 Feb 2017 15:22:52 -0500
-Subject: [PATCH] cmd/compile: add opcode flag hasSideEffects for do-not-remove
-
-Added a flag to generic and various architectures' atomic
-operations that are judged to have observable side effects
-and thus cannot be dead-code-eliminated.
-
-Test requires GOMAXPROCS > 1 without preemption in loop.
-
-Fixes #19182.
