Add Windows ARM64 support #81

Closed dennisameling closed 1 year ago

dennisameling commented 1 year ago

This adds ARM64 support to the cv2pdb.vcxproj build. Needed for Git for Windows ARM64 support.

The original purpose of cv2pdb is to translate old style CodeView debug information of the reference D compiler to pdb files. Later support for DWARF as emitted by the gcc based D compiler was added. The code in demangle.cpp is used to convert the mangled symbols of D functions or variables back to human readable form. It is unlikely to be useful for translating C++ debug information.

The code failing to compile is inline assembly that converts 80-bit floating point real values to something the C++ compiler understands, namely 64-bit floating point. I doubt that you will need that on ARM, so if you replace the usage of #ifdef _M_X64 with #ifndef _M_X86, you will just have to implement cvt80to64() which could error out if it is called for ARM builds.

Thanks for the hint! Have implemented the changes as you suggested. Here's a successful CI run: https://github.com/dennisameling/cv2pdb/actions/runs/3077972033

Curious to hear what you think!
