From 03d89412981a7681971bc77edba1669595763030 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 7 Apr 2014 16:05:48 +0900 Subject: [PATCH] perf probe: Use dwarf_getcfi_elf() instead of dwarf_getcfi() The dwarf_getcfi() only checks .debug_frame section for CFI, but as most binaries only have .eh_frame it'd return NULL and it makes some variables inaccessible. Using dwarf_getcfi_elf (along with dwarf_getelf()) allows to show and add probe to more variables.
