New submission from Ron Adam <ron3...@gmail.com>: The following changes cleanup the eval loop and result in a pretty solid 2 to 3% improvement in pybench for me.
And it is about 5% faster for long generators. * Change why enum type to int and #defines. And moved the why defines to opcode.h so that they can be seen by the genrator objects after a yield, return, or exception. * Added an "int f_why" to frames so the generator can see why it returned from a send. * Refactored generator obj so it can use the "f->f_why" to determine what to do without having to do several checks first. * Moved the generator specific execption save/swap/and clear out of the cevel main loop. No need to check for those on every function call. The only test that fails is the frame size is test_sys. I left that in for now so someone could check that, and tell me if it's ok to fix it, or if I need to do something else. I also considered putting the why on the tstate object. It might save some memory as there wouldn't be as many of those. ---------- components: Interpreter Core files: f_why.diff keywords: patch messages: 149583 nosy: ron_adam priority: normal severity: normal status: open title: Move generator specific sections out of ceval. type: performance versions: Python 3.3 Added file: http://bugs.python.org/file23969/f_why.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13607> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
