New submission from Demur Rumed <junkm...@hotmail.com>: DUP_TOPX(3) is never used, nor is ROT_FOUR. This patch removes the opcodes, replacing DUP_TOPX with DUP_TOP_TWO
Oddly, at least with pybench, use of PREDICT(BINARY_SUBSCR) in DUP_TOP_TWO seems to show an always right PREDICT as slower than FAST_DISPATCH ---------- components: Interpreter Core files: duptoptwo.patch keywords: patch messages: 110035 nosy: serprex priority: normal severity: normal status: open title: Replace DUP_TOPX with DUP_TOP_TWO type: performance Added file: http://bugs.python.org/file17949/duptoptwo.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9225> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
