Demur Rumed added the comment: Attaching first iteration. Very drafty. Still need to fix test_dis; will run test suite this evening. Perf on pybench went from 16.5s to 17.5s. It was 18.3s prior to reintroducing use of fast_function. Code still needs clean up besides investigation into how to optimize
Changes not described in the original patch concept: I made CALL_FUNCTION_EX oparg carry 2 flag bits on whether there's a kwdict or a vararg tuple. Code may be simpler to only have kwdict be optional. BUILD_MAP_UNPACK_WITH_CALL was modified to only use the highest bit of the 2nd byte to track where function_pos is. Most uses of BUILD_MAP_UNPACK_WITH_CALL is f(*va,**kw) so I chose to only set the highest bit when there isn't a positional unpacking. If we pushed an empty tuple then that flag bit could be removed ---------- keywords: +patch Added file: http://bugs.python.org/file43474/callfunc.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27213> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
