Subject: perf probe: Use elfutils-libdw for analyzing debuginfo
X-Git-Tag: v2.6.34-rc1~197^2~6
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=804b36068eccd8163ccea420c662fb5d1a21b141;p=pandora-kernel.git

perf probe: Use elfutils-libdw for analyzing debuginfo

Newer gcc introduces newer & richer debuginfo, and only libdw
in elfutils project can support it. So perf probe moves onto
elfutils-libdw from libdwarf.

Changes in v3:
 - Cast Dwarf_Addr/Dwarf_Word to uintmax_t for printf-formats.
 - Recover a sign-prefix which was removed in v2 by mistake.

Changes in v2:
 - Fix a type-casting bug in Makefile.
 - Cast Dwarf_Addr/Dwarf_Word to unsigned long long for printf-formats.
