Package: linux-tools-3.10
Version: 3.10-4
Severity: normal
Dear Maintainer,
The "perf record" command "-g <method>" option doesn't support a "dwarf"
method in Debian. As the "dwarf" allows operating on programs which
were compiled without a frame pointer (the default on amd64), "dwarf"
is very handy.
Here's what it does in debian:
$ perf record -g dwarf echo hi
callchain: Unknown -g option value: dwarf
usage: perf record [<options>] [<command>]
... etc ...
It looks like perf only supports "dwarf" if it was compiled with
libunwind, so I suppose Debian didn't have that installed when
compiling it.
Could you make sure perf is compiled with libunwind, so the very handy
"dwarf" -g method works?
Thanks,
-iles
