From eb21b31e487344fb0045b3ef7b14df9521b94952 Mon Sep 17 00:00:00 2001 From: Cherry Zhang Date: Fri, 22 Jan 2021 16:35:21 -0500 Subject: [PATCH] runtime: define dummy msanmove In msan mode we instrument code with msan* functions, including msanmove. In some configurations the code is instrumented by the compiler but msan is not actually linked in, so we need dummy definitions for those functions so the program links. msanmove is newly added in CL 270859 but a dummy definition in msan0.go was not added, causing link failures. Add it.
