In case of gcc inline assembler is used, which is also supported by
Intel but not clang. On Windows compiler intrinsics or WinAPI are
used. I believe Intel supports MSVC intrinsics on Windows. I'm not
sure what solution is suitable for clang as I don't know if it
supports any intrinsics and apparently it won't support inline
assembler any time soon.
