Summary: [webkitpy] perf profiler does not understand
--call-graph argument
Product: WebKit
Version: 528+ (Nightly build)
Platform: Unspecified
OS/Version: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Tools / Tests
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: rego at igalia.com

New version of perf profiler (3.13.6 in Debian testing) do not understand --call-graph argument.
So when running perf-tests enabling the profiler you get the following error:
callchain: Unknown --call-graph option value: --output
usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]
--call-graph <mode[,dump_size]>
setup and enables call-graph (stack chain/backtrace) recording: fp dwarf
Using -g seems enough (from the manual):
-g
Enables call-graph (stack chain/backtrace) recording.
