From: Cherry Zhang Date: Fri, 22 Jan 2021 21:35:21 +0000 (-0500) Subject: runtime: define dummy msanmove X-Git-Tag: go1.16rc1~32 X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=eb21b31e487344fb0045b3ef7b14df9521b94952;p=gostls13.git 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.
