Raymond Hettinger <rhettin...@users.sourceforge.net> added the comment:
Recommend having both MAP_ADD and STORE_MAP. The latter is repeated often in a typical dict literal so it needs to be compact and fast. The former needs the flexibility of the offset argument to be workable in a dict comprehension. I also like that MAP_ADD eliminates the need for the awkward ROT_TWO stack re-arrangement. Also, MAP_ADD can include a PREDICT(JUMP_ABSOLUTE) for a further speed-up. All in all, this is a nice clean-up and speed-up that more than justifies a second opcode. ---------- assignee: rhettinger -> pitrou _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue2183> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
