I introduced a new target triple "x86_64-uefi" in Clang and been incrementally landing changes to support this triple.  The `__UEFI__` predefine is set when x86_64-uefi triple is used. This triple does not set `_WIN32` and other windows specific predefines.  At this point, this triple is in developmental stage. It will be good to have a pre-commit CI set up when the support is mature. I do not know if we are quite there yet at this point. Thank you.
