From 0058aef65eda9c9dde8253af702d542ba7eef697 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 3 Dec 2013 09:23:08 +0200 Subject: [PATCH] perf symbols: Retain symbol source file name to lookup source line numbers Currently, lookup of an ip's source file name and line number is done using the dso file name. Instead retain the file name used to lookup the dso's symbols and use that.
