Mapping raw addresses in JIT-generated assembly all the way back to Python is a bit difficult, but that's what vmprof tries to do. I can imagine a solution based on vmprof. For now, try to run pypy in the vtune branch together with vmprof: https://github.com/vmprof/vmprof-python . I think the vmprof log file contains some information that does the mapping we're looking for. For now we're not actively developing the vtune branch any more, but maybe we should. I should add that my copy of vtune-amplifier-xe started refusing to work, with "Error - no valid license - license expired" and no hint about if and how to renew that license, so that put me off. A bientôt, Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org https://mail.python.org/mailman/listinfo/pypy-dev
