Neil Schemenauer <nas-pyt...@arctrix.com> added the comment: I wonder if I should drop PR 4682. I spent some more time working on it today. I switched to the same scheme as Serhiy for the no-exception case, i.e. push a single NULL value, rather than six NULLs. In ceval, we need to handle the non-exception case specially anyhow so I think it better to avoid the "stack churn". With the micro-benchmarks that Serhiy posted, PR 4682 is as fast or slightly faster than PR 5006. Doesn't really matter in real code though.
I did not push my latest changes as I did not fix the frame.f_lineno issue yet. I think it is fixable without major changes. Should I bother though? Is there some other reason to prefer duplicating the final bodies rather than using a subroutine jump (as in 5006)? A very minor speedup is not worth it I think because the compiler is a bit more complicated. The settrace logic is more complicated too. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue17611> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
