Bug report
Bug description:
On Windows, sysconfig.get_platform() checks for the string amd64 (for 64 intel) in sys.version.
This is the value of sys.version for python 3.14.3 (64 bit) compiled with clang 22.1.0
>>> sys.version '3.14.3 (main, Mar 2 2026, 14:42:29) [Clang 22.1.0 (https://github.com/llvm/llvm-project 4434dabb69916856b824f68a64b0' >>> sysconfig.get_platform() 'win32' >>> import platform >>> platform.architecture()[0] '64bit'
As visible, there is no amd64 in sys.version, because it is truncated. This causes problem when installing native package using pip because cp314-cp314-amd64 is not in the list of supported tags. Instead, the supported tags list become
Compatible tags: 48
cp314-cp314-win32
cp314-abi3-win32
cp314-none-win32
cp313-abi3-win32
cp312-abi3-win32
cp311-abi3-win32
cp310-abi3-win32
