* Issue #26110: Add LOAD_METHOD/CALL_METHOD opcodes.Yury Selivanov2016-12-141-0/+3
| | | | | | | Special thanks to INADA Naoki for pushing the patch through the last mile, Serhiy Storchaka for reviewing the code, and to Victor Stinner for suggesting the idea (originally implemented in the PyPy project).
* Issue #28257: Improved error message when pass a non-iterable asSerhiy Storchaka2016-10-021-2/+3
| | | | a var-positional argument. Added opcode BUILD_TUPLE_UNPACK_WITH_CALL.
* Rework CALL_FUNCTION* opcodesVictor Stinner2016-09-091-9/+4
| | | | | | | | | | | | | | | | | | | Issue #27213: Rework CALL_FUNCTION* opcodes to produce shorter and more efficient bytecode: * CALL_FUNCTION now only accepts position arguments * CALL_FUNCTION_KW accepts position arguments and keyword arguments, but keys of keyword arguments are packed into a constant tuple. * CALL_FUNCTION_EX is the most generic, it expects a tuple and a dict for positional and keyword arguments. CALL_FUNCTION_VAR and CALL_FUNCTION_VAR_KW opcodes have been removed. 2 tests of test_traceback are currently broken: skip test, the issue #28050 was created to track the issue. Patch by Demur Rumed, design by Serhiy Storchaka, reviewed by Serhiy Storchaka and Victor Stinner.
