[Python-Dev] Wordcode: new regular bytecode using 16-bit units (original) (raw)

So code that depends on iterating through bytecode via HAS_ARG is going to break...

Darn it. :/

What is the value of HASARG going to be now?

I asked Demur to keep HASARG(). Not really for backward compatibility, but for the dis module: to keep a nice assembler. There are also debug traces in ceval.c which use it. For ceval.c, we might use HASARG() to micro-optimize oparg=0 (hardcode 0 rather than reading the bytecode) for operators with no argument. Or maybe it's completly useless :-) Victor -------------- next part -------------- An HTML attachment was scrubbed...
