title: CLANG - what platforms are supported for cross-compilation?
body: <p>Sorry for the broad question; spending several minutes on their <a href="http://clang.llvm.org/index.html" rel="nofollow">homepage</a>, the only information that I could find was how awesome the compiler is.</p>
  
  <p>What platforms does CLANG support (I am mainly interested in embedded)? ARM, AVR, RTOS etc.
  Are there other popular front-ends to LLVM, that are relevant to the question?</p>
