From 42d7a9107d83223a5fcecc6732d626a6c074cbc2 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 30 Sep 2019 15:48:12 -0300 Subject: perf annotate: Fix arch specific ->init() failure errors They are called from symbol__annotate() and to propagate errors that can help understand the problem make them return what symbol__strerror_disassemble() known, i.e. errno codes and other annotation specific errors in a special, out of errnos, range.
