* gh-117139: Convert the evaluation stack to stack refs (#118450)Ken Jin2024-06-261-9/+9
| | | | | | | | | | | | | | | | | This PR sets up tagged pointers for CPython. The general idea is to create a separate struct _PyStackRef for everything on the evaluation stack to store the bits. This forces the C compiler to warn us if we try to cast things or pull things out of the struct directly. Only for free threading: We tag the low bit if something is deferred - that means we skip incref and decref operations on it. This behavior may change in the future if Mark's plans to defer all objects in the interpreter loop pans out. This implies a strict stack reference discipline is required. ALL incref and decref operations on stackrefs must use the stackref variants. It is unsafe to untag something then do normal incref/decref ops on it. The new incref and decref variants are called dup and close. They mimic a "handle" API operating on these stackrefs. Please read Include/internal/pycore_stackref.h for more information! --------- Co-authored-by: Mark Shannon <9448417+markshannon@users.noreply.github.com>

* gh-119821: Support non-dict globals in LOAD_FROM_DICT_OR_GLOBALS (#119822)Jelle Zijlstra2024-05-311-6/+1
| | | | | | | | | Support non-dict globals in LOAD_FROM_DICT_OR_GLOBALS The implementation basically copies LOAD_GLOBAL. Possibly it could be deduplicated, but that seems like it may get hairy since the two operations have different operands. This is important to fix in 3.14 for PEP 649, but it's a bug in earlier versions too, and we should backport to 3.13 and 3.12 if possible.

* gh-119180: Add LOAD_COMMON_CONSTANT opcode (#119321)Jelle Zijlstra2024-05-221-1/+1
| | | | | | | | | | The PEP 649 implementation will require a way to load NotImplementedError from the bytecode. @markshannon suggested implementing this by converting LOAD_ASSERTION_ERROR into a more general mechanism for loading constants. This PR adds this new opcode. I will work on the rest of the implementation of the PEP separately. Co-authored-by: Irit Katriel <1055913+iritkatriel@users.noreply.github.com>

* gh-117045: Add code object to function version cache (#117028)Guido van Rossum2024-03-211-7/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | Changes to the function version cache: - In addition to the function object, also store the code object, and allow the latter to be retrieved even if the function has been evicted. - Stop assigning new function versions after a critical attribute (e.g. `__code__`) has been modified; the version is permanently reset to zero in this case. - Changes to `__annotations__` are no longer considered critical. (This fixes gh-109998.) Changes to the Tier 2 optimization machinery: - If we cannot map a function version to a function, but it is still mapped to a code object, we continue projecting the trace. The operand of the `_PUSH_FRAME` and `_POP_FRAME` opcodes can be either NULL, a function object, or a code object with the lowest bit set. This allows us to trace through code that calls an ephemeral function, i.e., a function that may not be alive when we are constructing the executor, e.g. a generator expression or certain nested functions. We will lose globals removal inside such functions, but we can still do other peephole operations (and even possibly [call inlining](https://github.com/python/cpython/pull/116290), if we decide to do it), which only need the code object. As before, if we cannot retrieve the code object from the cache, we stop projecting.
