From 3843b05d6ef20acbd4b0043e4ab7536602eb10ae Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Wed, 21 Nov 2012 13:49:44 +0100 Subject: [PATCH] perf symbols: Ignore ABS symbols when loading data maps When loading symbols in a data mapping, ABS symbols (which has a value of SHN_ABS in its st_shndx) failed at elf_getscn(). And it marks the loading as a failure so already loaded symbols cannot be fixed up. I'm not sure what should be done. Just ignore them for now. :) Signed-off-by: Namhyung Kim Cc: Andi Kleen Cc: Ingo Molnar Cc: Jiri Olsa Cc: Namhyung Kim Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/r/1353502185-26521-19-git-send-email-eranian@google.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/symbol-elf.c | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/tools/perf/util/symbol-elf.c b/tools/perf/util/symbol-elf.c index db0cc92cf2ea..f63557b59c06 100644 --- a/tools/perf/util/symbol-elf.c +++ b/tools/perf/util/symbol-elf.c @@ -718,6 +718,17 @@ int dso__load_sym(struct dso *dso, struct map *map, sym.st_value); used_opd = true; } + /* + * When loading symbols in a data mapping, ABS symbols (which + * has a value of SHN_ABS in its st_shndx) failed at + * elf_getscn().
