This moves the bytecode to the end of the corresponding
PyCodeObject, and quickens it in-place.Related changes:
PyCodeObjectis now more compact. I've removed the almost-always-unusedco_varnames,co_freevars, andco_cellvarsmember caches, and rearranged someintmembers to fill some holes in the struct on 64-bit builds.co_codehas been removed and replaced with_PyCode_GetCode, andco_quickenedandco_firstinstrhave been replaced with_PyCode_CODE._PyOpcode_Deoptis a new mapping from all opcodes to their un-quickened forms._PyOpcode_InlineCacheEntriesis renamed to_PyOpcode_Caches,_Py_IncrementCountAndMaybeQuickenis renamed to_PyCode_Warmup,_Py_Quickenis renamed to_PyCode_Quicken, and_co_quickenedis renamed to_co_code_adaptive(and is now a read-onlymemoryview).https://bugs.python.org/issue46841
