From fd4be13067ef65bf33b965a18c717889305d5fea Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 11 Apr 2016 22:03:56 -0300 Subject: perf evsel: Allow unresolved symbol names to be printed as addresses The fprintf_sym() and fprintf_callchain() methods now allow users to change the existing behaviour of showing "[unknown]" as the name of unresolved symbols to instead show "[0x123456]", i.e. its address. The current patch doesn't change tools to use this facility, the results from 'perf trace' and 'perf script' cotinue like: 70.109 ( 0.001 ms): qemu-system-x8/10153 poll(ufds: 0x7f2d93ffe870, nfds: 1) = 0 Timeout [unknown] (/usr/lib64/libc-2.22.so) [unknown] (/usr/lib64/libspice-server.so.1.10.0) [unknown] (/usr/lib64/libspice-server.so.1.10.0) [unknown] (/usr/lib64/libspice-server.so.1.10.0) start_thread+0xca (/usr/lib64/libpthread-2.22.so) __clone+0x6d (/usr/lib64/libc-2.22.so) The next patch will make 'perf trace' use the new formatting.
