"LLVM allows code to be compiled statically, as it is under the
traditional GCC system, or left for late-compiling from the IF to
machine code in a just-in-time compiler (JIT) in a fashion similar to
Java".
LLVM is a lot more than just a C compiler in XCode. It's a whole generic compiler and runtime architecture.
For example, it's already used in Leopard to compile OpenGL shaders into bytecode, which is then translated at runtime into either GPU shader instructions, or if the GPU doesn't support those, into CPU instructions that do the same operation more slowly.
I believe Apple's MacRuby project involves compiling Ruby using LLVM.
