[LLVMdev] Why JITC?

[Mike Hearn]

I guess this is slightly offtopic, but the post about the JIT and garbage
collection made me wonder why LLVM supports JIT compilation at all. It has
much smaller scope for optimisation due to the speed requirements, takes
more memory and causes the same work to be repeated over and over for each
execution. 

What reason is there for anything to use JIT compilation over
ahead-of-time compiling to native code?
