Mark Shannon <m...@hotpy.org> added the comment:
frame.f_lasti and traceback.tb_lasti are best left as byte offsets. There is no guarantee that we won't go back to variable length instructions. For example, a "LONG_JUMP" instruction which is 4 bytes long and takes a 3 byte offset might well be a worthwhile extension. However, changing bytecode offsets and the internal representation of frame.f_lasti will reduce the number of "EXTENDED_ARG"s by 60% or more and makes interpreter dispatch a tad more efficient. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue27129> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
