The argument to CALL_FUNCTION is overloaded to show both the number of positional arguments and keyword arguments (shifted by 8-bits):
>>> dis("foo(10, opt=True)")
1 0 LOAD_NAME 0 (foo)
3 LOAD_CONST 0 (10)
6 LOAD_CONST 1 ('opt')
9 LOAD_CONST 2 (True)
12 CALL_FUNCTION 257
15 RETURN_VALUE
It is not obvious that the 257 argument causes three stack arguments to be popped.
The disassembly should add a parenthetical to explain the composition:
>>> dis("foo(10, opt=True)")
1 0 LOAD_NAME 0 (foo)
3 LOAD_CONST 0 (10)
6 LOAD_CONST 1 ('opt')
9 LOAD_CONST 2 (True)
12 CALL_FUNCTION 257 (1 positional, 1 keyword pair)
15 RETURN_VALUE

I am posting an unfinished patch (needs additional tests and possibly documentation) to get feedback on whether it would make sense to wait for issue11816 refactoring before implementing this. Note the code duplication between disassemble and _disassemble_bytes. I am also not happy about the need for another constant exported from opcode. |
