It is a C/C++/Obj-C compiler & does static analysis, has
backends for multiple processor types as well as C as a
target, a lot of optimization tricks etc.  See llvm.org.  But
frankly, I think they have lost the plot. C is basically a
portable assembly programming language & in my highly biased
opinion a C compiler should do no more than peephole
optimizations.  If you want more, might as well use a high
level language.
