New submission from David Turner <[EMAIL PROTECTED]>: This patch adds an optimization to the peephole optimizer for the common case of:
def func(...): ... retval = ... return retval Before the patch, the compiler would generate STORE_FAST 3 LOAD_FAST 3 RETURN_VALUE The store and load are pointless, as the local 3 (or whatever) is never used again. This patch makes the peephole optimizer optimize them out. ---------- components: None files: peephole-return-temp.diff keywords: patch messages: 74853 nosy: novalis_dt severity: normal status: open title: Peephole optimization: returning a temp versions: Python 2.7 Added file: http://bugs.python.org/file11811/peephole-return-temp.diff _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue4134> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
