New submission from Serhiy Storchaka: There are many bytecode changes in 3.6, but seems most of them are not documented (besides short line in _bootstrap_external.py).
* The bytecode now uses 16 bit units (wordcode) (issue26647). * Added FORMAT_VALUE opcode (issue25483). * Added BUILD_CONST_KEY_MAP opcode (issue27140). * Added BUILD_STRING opcode (issue27078). * Added BUILD_TUPLE_UNPACK_WITH_CALL opcode (issue28257). * Added SETUP_ANNOTATIONS and STORE_ANNOTATION opcodes (issue27985). * Changed CALL_FUNCTION, CALL_FUNCTION_KW and BUILD_MAP_UNPACK_WITH_CALL opcodes, removed CALL_FUNCTION_VAR, CALL_FUNCTION_VAR_KW opcodes, added CALL_FUNCTION_EX opcode (issue27213). * Changed MAKE_FUNCTION opcode, removed MAKE_CLOSURE opcode (issue27095). * Not related to the bytecode itself: lineno delta of code.co_lnotab now is signed (issue26107). There are third-party projects that need correct information about bytecode changes. ---------- assignee: docs@python components: Documentation messages: 281788 nosy: docs@python, serhiy.storchaka priority: high severity: normal stage: needs patch status: open title: Document bytecode changes in 3.6 type: enhancement versions: Python 3.6, Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28810> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
