Raymond Hettinger added the comment: The second version of the patch mostly looks fine.
The prediction from DUP_TOP_TWO to BINARY_SUBSCR is questionable. Because compile.c only uses it one context, the prediction rate is 100%; however, there is no intrinsic relationship between the two opcodes, so the prediction is happenstance and fragile. Reconsider whether you really want this prediction pairing. ---------- assignee: rhettinger -> serhiy.storchaka _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27255> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
