Message-Id: <1358264386-24633-18-git-send-email-eranian@google.com> Date: Tue, 15 Jan 2013 16:39:45 +0100 From: Stephane Eranian <eranian@...gle.com> To: linux-kernel@...r.kernel.org Cc: peterz@...radead.org, mingo@...e.hu, ak@...ux.intel.com, acme@...hat.com, jolsa@...hat.com, namhyung.kim@....com, Namhyung Kim <namhyung@...nel.org> Subject: [PATCH v6 17/18] perf tools: Ignore ABS symbols when loading data maps From: Namhyung Kim <namhyung.kim@....com> 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. :) Cc: Stephane Eranian <eranian@...gle.com> Signed-off-by: Namhyung Kim <namhyung@...nel.org> --- tools/perf/util/symbol-elf.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/tools/perf/util/symbol-elf.c b/tools/perf/util/symbol-elf.c index db0cc92..00cf128 100644 --- a/tools/perf/util/symbol-elf.c +++ b/tools/perf/util/symbol-elf.c @@ -719,6 +719,9 @@ int dso__load_sym(struct dso *dso, struct map *map, used_opd = true; } + if (sym.st_shndx == SHN_ABS) + continue; + sec = elf_getscn(runtime_ss->elf, sym.st_shndx); if (!sec) goto out_elf_end; -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
