Is your compiler written in C++ or something that can interface with
it easily?  If so, you should probably check out the JIT, and the
tutorial here:

In particular, this bit is relevant to using a JIT:

It sounds like you're generating LLVM IL and dumping it to a .ll file
in your own compiler, so you'll probably have to just add some driver
code to your compiler that drives llvm-as, opt, llvm-link, and llc.
