 From the LLVM home page, "[LLVM has] back-ends for the X86, X86-64,  
PowerPC 32/64, ARM, Thumb, IA-64, Alpha and SPARC architectures, a  
back-end which emits portable C code, and a Just-In-Time compiler for  
X86, X86-64, PowerPC 32/64 processors."

That's reasonably portable, and of course the more involved the  
community is in this project, the more likely that Clang will work  
well on all of these architectures.

It's the LLVM license, which is a BSD-like license. You can check it  
out here:
