Ticket #506 (closed todo: fixed)
generate callgrind output
|Reported by:||coke||Owned by:|
Parrot currently only supports profiling at the opcode level; we need to generate profiling information for everything.
From the original RT ( http://rt.perl.org/rt3/Ticket/Display.html?id=58250)
Provide a mechanism (for example, compiling with -DPARROT_CALLGRIND), that forces each Sub invocation to be reported in a standard callgrind output (http://valgrind.org/docs/manual/cl-format.html). Future bonus points for providing similar support for opcodes (probably replacing the -p option). Double future super bonus points for combining the output of the C-level callgrind output (available from valgrind) with the parrot sub and opcode information into a single report.  chromatic's original suggestion was an alternate runcore. I think this suggestion makes more sense since we want this for more than opcode dispatch, but I could be wrong.
