* gh-92063: Enforce types in specialized PRECALL opcodes (GH-92068)Dennis Sweeney2022-04-301-16/+27
| | | | | | | | | * Check the types of PRECALL_METHOD_DESCRIPTOR_FAST_WITH_KEYWORDS * fix PRECALL_NO_KW_METHOD_DESCRIPTOR_NOARGS as well * fix PRECALL_NO_KW_METHOD_DESCRIPTOR_O * fix PRECALL_NO_KW_METHOD_DESCRIPTOR_FAST

* gh-91719: Add pycore_opcode.h internal header file (#91906)Victor Stinner2022-04-251-0/+1
| | | | | | | | | | | Move the following API from Include/opcode.h (public C API) to a new Include/internal/pycore_opcode.h header file (internal C API): * EXTRA_CASES * _PyOpcode_Caches * _PyOpcode_Deopt * _PyOpcode_Jump * _PyOpcode_OpName * _PyOpcode_RelativeJump
* gh-89279: In ceval.c, redefine some macros for speed (#32387)Guido van Rossum2022-04-221-13/+60
| | | | | | | | | | | Macros Py_DECREF, Py_XDECREF, Py_IS_TYPE, _Py_atomic_load_32bit_impl and _Py_DECREF_SPECIALIZED are redefined as macros that completely replace the inline functions of the same name. These three came out in the top four of functions that (in MSVC) somehow weren't inlined.

* GH-91719: Make MSVC generate somewhat faster switch code (#91718)Guido van Rossum2022-04-211-2/+4
| | | | | | | | | | | Apparently a switch on an 8-bit quantity where all cases are present generates a more efficient jump (doing only one indexed memory load instead of two). So we make opcode and use_tracing uint8_t, and generate a macro full of extra `case NNN:` lines for all unused opcodes. See https://github.com/faster-cpython/ideas/issues/321#issuecomment-1103263673

| | | | | | | | | | | | | | | | | | | * Moves the bytecode to the end of the corresponding PyCodeObject, and quickens it in-place. * Removes the almost-always-unused co_varnames, co_freevars, and co_cellvars member caches * _PyOpcode_Deopt is a new mapping from all opcodes to their un-quickened forms. * _PyOpcode_InlineCacheEntries is renamed to _PyOpcode_Caches * _Py_IncrementCountAndMaybeQuicken is renamed to _PyCode_Warmup * _Py_Quicken is renamed to _PyCode_Quicken * _co_quickened is renamed to _co_code_adaptive (and is now a read-only memoryview). * Do not emit unused nonzero opargs anymore in the compiler.
* bpo-46850: Remove _PyEval_CallTracing() function (GH-32019)Victor Stinner2022-03-211-4/+7
| | | | Remove the private undocumented function _PyEval_CallTracing() from the C API. Call the public sys.call_tracing() function instead.
* bpo-46850: Remove _PyEval_GetCoroutineOriginTrackingDepth() (GH-32018)Victor Stinner2022-03-211-4/+10
| | | | | | | | | | | | | | | Remove the private undocumented function _PyEval_GetCoroutineOriginTrackingDepth() from the C API. Call the public sys.get_coroutine_origin_tracking_depth() function instead. Change the internal function _PyEval_SetCoroutineOriginTrackingDepth(): * Remove the 'tstate' parameter; * Add return value and raises an exception if depth is negative; * No longer export the function: call the public sys.set_coroutine_origin_tracking_depth() function instead. Uniformize also function declarations in pycore_ceval.h.

* bpo-46940: Don't override existing AttributeError suggestion information ↵Pablo Galindo Salgado2022-03-071-3/+6
| | | | | | | | | | | | (GH-31710) When an exception is created in a nested call to PyObject_GetAttr, any external calls will override the context information of the AttributeError that we have already placed in the most internal call. This will cause the suggestions we create to nor work properly as the attribute name and object that we will be using are the incorrect ones. To avoid this, we need to check first if these attributes are already set and bail out if that's the case.
