Well, I don't like it - but we already have similar patterns to cover some asm complications so I didn't mind. Apparently Clang is very close to being able to build a working Linux kernel, right? In that sense it would be unfair to expect it to not have various legacies, missing features and quirks - just like the kernel has dozens of GCC related workarounds.
