Subject: perf probe: Use dwarf_getcfi_elf() instead of dwarf_getcfi()
X-Git-Tag: omap-for-v3.16/pm-signed~99^2~1^2~4
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=03d89412981a7681971bc77edba1669595763030;p=pandora-kernel.git

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.
