New submission from Brandt Bucher <brandtbuc...@gmail.com>:
This patch adds four new opcode predictions: BUILD_MAP_UNPACK_WITH_CALL -> CALL_FUNCTION_EX: - Emitted whenever more than one map of **kwargs is unpacked into a call. - Pair *always* occurs together. LOAD_BUILD_CLASS -> LOAD_CONST: - Emitted whenever a class is defined *without* the use of cell vars. - Occurs ~93% of the time, in my analysis. LOAD_BUILD_CLASS -> LOAD_CLOSURE: - Emitted whenever a class is defined *with* the use of cell vars. - Occurs the other ~7% of the time LOAD_ASSERTION_ERROR -> RAISE_VARARGS: - Emitted whenever the one-argument form of "assert" is used. - Occurs ~91% of the time. ---------- components: Interpreter Core messages: 353472 nosy: brandtbucher priority: normal severity: normal status: open title: Opcode predictions for asserts, class definitions, and some calls. type: performance versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38310> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
