But then how do you index the cache, do you keep a count of the current opcode number? If I remember correctly, CPython has some opcodes taking 1 byte, and some taking 3 bytes, so the offset into the bytecode cannot be easily mapped to a bytecode number.
Here are a few links that might explain the idea better: https://github.com/1st1/cpython/blob/opcache5/Python/ceval.c#L1229 https://github.com/1st1/cpython/blob/opcache5/Python/ceval.c#L2610 https://github.com/1st1/cpython/blob/opcache5/Objects/codeobject.c#L167 Yury _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
