Bug description:
Hi,
I'm trying to use perf's libunwind support in 13.04 with kernel
3.11.0-12-generic on amd64. Typically you can do this by using the
"-g dwarf" flag, but it appears the perf command included in linux-
tools-3.11.0-12-generic was not compiled with libunwind. This may be
as simple as the build machine didn't have libunwind installed.
Having dwarf support in perf with default Ubuntu kernels would be very
useful as it provides a way to get profiling information when
-fomitframepointer is used.
Relevant upstream code:
https://github.com/torvalds/linux/blob/v3.11/tools/perf/Makefile#L459
https://github.com/torvalds/linux/blob/v3.11/tools/perf/builtin-record.c#L758
Let me know if I can provide any other information.
