The patch adds platform implementation for win32 llvm reusing platform/switch_aarch64_gcc.h and fixes the stackref type to int64_t, as long is considered to be 32bit by llvm-mingw. The .pyd extension for greenlet can be manually built using: https://github.com/mstorsjo/llvm-mingw. How to set the env to build a working .pyd: * Install mingw64 or mingw32 * Download the llvm-mingw binaries and add them to path https://github.com/mstorsjo/llvm-mingw/releases * Download a Python 3.9 build for ARM64 and unzip in greenlet/src/greenlet https://github.com/ader1990/cpython-builder/actions/runs/377798403 How to build the .pyd using llvm-mingw: * cd greenlet/src/greenlet * aarch64-w64-mingw32-clang -c greenlet.c -o greenlet.o -I./cpython/include * aarch64-w64-mingw32-clang -shared -o _greenlet.cp39-win_arm64.pyd greenlet.o -L./cpython/libs -l:python3.lib -l:python39.lib Partially-fixes: python-greenlet#220

Hello,
I am trying to use greenlet with Python 3.8 / 3.9 on Windows ARM64, but there is a compilation issue when I try building it using VS Studio 2017 / 2019:
It seems there has to be a special switch implementation here for ARM64, but currently I do not know how to tackle it:
https://github.com/python-greenlet/greenlet/blob/master/src/greenlet/slp_platformselect.h#L8
Can anyone help me with some pointers for the win32 ARM64 switch?
Thank you,
Adrian
