Hi,
While writing some testcases for the call abi switching for x86_64<->w64 I
came to the point, that it would be may good to add the builtin types and
functions for the different calling abi, too.
For the target default abi it would be

For x86_64->w64 I would like to add the type __builtin_w64_va_list, and
the functions __builtin_w64_va_copy, ....
For w64->x86_64 I would like to add the type __builtin_x86_64_va_list,
and the functions __builtin_x86_64_va_copy, ....
Is this approach ok to prepare a patch for it?
