*	bpo-29882: _Py_popcount32() doesn't need 64x64 multiply (GH-30774)	Victor Stinner	2022-01-21	1	-1/+1
\| \| \|	32x32 bits multiply is enough for _Py_popcount32().
*	bpo-41617: Add _Py__has_builtin() macro (GH-23260)	Victor Stinner	2020-11-13	1	-9/+6
\| \| \| \| \| \| \| \| \| \| \|	Fix building pycore_bitutils.h internal header on old clang version without __builtin_bswap16() (ex: Xcode 4.6.3 on Mac OS X 10.7). Add a new private _Py__has_builtin() macro to check for availability of a preprocessor builtin function. Co-Authored-By: Joshua Root <jmr@macports.org> Co-authored-by: Joshua Root <jmr@macports.org>
*	bpo-41617: Fix pycore_bitutils.h to support clang 3.0 (GH-22042)	Victor Stinner	2020-09-01	1	-4/+6
\| \| \|	__builtin_bswap16() is not available in LLVM clang 3.0.
*	bpo-29782: Consolidate _Py_Bit_Length() (GH-20739)	Niklas Fiekas	2020-06-15	1	-4/+43
\| \| \| \| \| \| \| \| \| \|	In GH-2866, _Py_Bit_Length() was added to pymath.h for lack of a better location. GH-20518 added a more appropriate header file for bit utilities. It also shows how to properly use intrinsics. This allows reconsidering bpo-29782. * Move the function to the new header. * Changed return type to match __builtin_clzl() and reviewed usage. * Use intrinsics where available. * Pick a fallback implementation suitable for inlining.
*	bpo-29882: Add _Py_popcount32() function (GH-20518)	Victor Stinner	2020-06-08	1	-0/+138
	* Rename pycore_byteswap.h to pycore_bitutils.h. * Move popcount_digit() to pycore_bitutils.h as _Py_popcount32(). * _Py_popcount32() uses GCC and clang builtin function if available. * Add unit tests to _Py_popcount32().
