Linux Clang can build a kernel now. "The kernel can successfully boot to runlevel 5 (aka X + networking) on the Macbook, both on bare metal and in Qemu. The kernel can successfully boot to runlevel 3 on a secondary test machine, a microATX desktop box (Intel Atom). I haven't tried to start X on this box yet. The kernel can self-host; I am currently running a 'fourth generation' self-hosted Linux kernel built by a 'fourth generation' Clang."

Member since:

It has been stated by a few kernel devs (I think Linus, but I cant find a reference), that while it may be possible, it is extremely difficult to do low level kernel development in C without leaning on some non-standard functionality in the compiler. Meaning that it they wanted to support multiple compilers they would have to conditionalize the living hell out of the headers/build system OR make the other compilers behave the same way as GCC. The later is much easier in the long haul (and is essentially what Clang is trying to do for the most part).
