title: Is it possible to compile Linux kernel with something other than gcc
body: <p>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 arose when I thought about answers to: <a href="https://stackoverflow.com/questions/687813/are-c-int-operations-atomic-on-the-mips-architecture">Are C++ int operations atomic on the mips architecture</a> </p>
  
  <p>It seems that the atomicity of some operations depends not only on the cpu architecture, but also on used compiler. So, I wonder if in Linux world some compiler other than gcc even exists.</p>
