Is it possible to compile Linux kernel with something other than gcc

Question

I wonder if someone managed to compile the Linux kernel with some other compiler than gcc. Or if someone have ever tried? Question may seem to be silly or academic, but it a

I am just now working on compile Linux kernel using Open64 for MIPS archtecture, and some other guys are now just working for make Open64 can build for X86 arch. Now the kernel can partly run, and still have Run fail errors.

However for the atomic problem, at least i have not come up with it. And I do not think it is really a problem.The reasons are:

1. The Linux kernel have already been a collection of source code, which can successfully build with GCC, so it is only the compiler's problem if it can not build it, or the built kernel runs fail.

2. If a compiler want to successfully build Linux kernel, it should obide the GNU C Extension, and this extension will give a clear discription of what a atomic operation is, so such a compile only need to generate code according to this extension.
