[PATCH 2/2] perf tools: Remove warnings on JIT samples for srcline sort key

From: Namhyung Kim
Date: Sun Oct 14 2012 - 23:40:07 EST


From: Namhyung Kim <namhyung.kim@xxxxxxx>

When using the srcline sort key with perf report, I see many lines of
warning related to JIT samples like below:

addr2line: '/tmp/perf-1397.map': No such file

Since it's not a ELF binary and doesn't provide such information, just
use the raw ip address.

Maybe you want fold this into patch #1 and I'm okay with it. :)
