* bpo-40302: Add pycore_byteswap.h header file (GH-19552)Victor Stinner2020-04-171-4/+4
| | | | | | | | | | | | | | Add a new internal pycore_byteswap.h header file with the following functions: * _Py_bswap16() * _Py_bswap32() * _Py_bswap64() Use these functions in _ctypes, sha256 and sha512 modules, and also use in the UTF-32 encoder. sha256, sha512 and _ctypes modules are now built with the internal C API.

* bpo-36635: Change pyport.h for Py_BUILD_CORE_MODULE define (GH-12853)Victor Stinner2019-04-171-2/+23
| | | | | | | | | | | | | | | | | | | | Change PyAPI_FUNC(type), PyAPI_DATA(type) and PyMODINIT_FUNC macros of pyport.h when Py_BUILD_CORE_MODULE is defined. The Py_BUILD_CORE_MODULE define must be now be used to build a C extension as a dynamic library accessing Python internals: export the PyInit_xxx() function in DLL exports on Windows. Changes: * Py_BUILD_CORE_BUILTIN and Py_BUILD_CORE_MODULE now imply Py_BUILD_CORE directy in pyport.h. * ceval.c compilation now fails with an error if Py_BUILD_CORE is not defined, just to ensure that Python is build with the correct defines. * setup.py now compiles _pickle.c with Py_BUILD_CORE_MODULE define. * setup.py compiles _json.c with Py_BUILD_CORE_MODULE define, rather than Py_BUILD_CORE_BUILTIN define * PCbuild/pythoncore.vcxproj: Add Py_BUILD_CORE_BUILTIN define.
* bpo-35758: Fix building on ARM + MSVC (gh-11531)Minmin Gong2019-01-211-1/+1
| | | | | | | | | | * Disable x87 control word for non-x86 targets On msvc, x87 control word is only available on x86 target. Need to disable it for other targets to prevent compiling problems. * Include immintrin.h on x86 and x64 only Immintrin.h is only available on x86 and x64. Need to disable it for other targets to prevent compiling problems.
* bpo-35059: Remove Py_STATIC_INLINE() macro (GH-10216)Victor Stinner2018-10-291-17/+0
| | | | "static inline" should be used directly. Forcing the compiler to inline is not recommended.
* bpo-35059: Add Py_STATIC_INLINE() macro (GH-10093)Victor Stinner2018-10-251-11/+28
| | | | | | | | | * Add Py_STATIC_INLINE() macro to declare a "static inline" function. If the compiler supports it, try to always inline the function even if no optimization level was specified. * Modify pydtrace.h to use Py_STATIC_INLINE() when WITH_DTRACE is not defined. * Add an unit test on Py_DECREF() to make sure that _Py_NegativeRefcount() reports the correct filename.

* bpo-30768: Recompute timeout on interrupted lock (GH-4103)Victor Stinner2017-10-241-0/+3
| | | | | | | | | | | | | | | | Fix the pthread+semaphore implementation of PyThread_acquire_lock_timed() when called with timeout > 0 and intr_flag=0: recompute the timeout if sem_timedwait() is interrupted by a signal (EINTR). See also the PEP 475. The pthread implementation of PyThread_acquire_lock() now fails with a fatal error if the timeout is larger than PY_TIMEOUT_MAX, as done in the Windows implementation. The check prevents any risk of overflow in PyThread_acquire_lock(). Add also PY_DWORD_MAX constant.

Add _Py_NO_INLINE: use __attribute__((noinline)) of GCC and Clang. It reduces the stack consumption, bytes per call, before => after: test_python_call: 1040 => 976 (-64 B) test_python_getitem: 976 => 912 (-64 B) test_python_iterator: 1120 => 1056 (-64 B) => total: 3136 => 2944 (- 192 B)

* | Issue #28618: Make hot functions using __attribute__((hot))Victor Stinner2016-11-111-2/+25
|/ | | | | | | | | | | | | | | | | | | | When Python is not compiled with PGO, the performance of Python on call_simple and call_method microbenchmarks depend highly on the code placement. In the worst case, the performance slowdown can be up to 70%. The GCC __attribute__((hot)) attribute helps to keep hot code close to reduce the risk of such major slowdown. This attribute is ignored when Python is compiled with PGO. The following functions are considered as hot according to statistics collected by perf record/perf report: * _PyEval_EvalFrameDefault() * call_function() * _PyFunction_FastCall() * PyFrame_New() * frame_dealloc() * PyErr_Occurred()
