Before going any further in this tutorial, you should look through the LLVM Language Reference Manual and convince yourself that the above LLVM IR is actually equivalent to the original function. Once you’re satisfied with that, let’s move on to actually generating it programmatically!

LLVM uses an explicit pass infrastructure to manage optimizations and various other things. A PassManager, as should be obvious from its name, manages passes: it is responsible for scheduling them, invoking them, and insuring the proper disposal after we’re done with them. For this example, we’re just using a trivial pass that prints out our module in textual form.
Now onto the interesting part: creating a populating a module. Here’s the first chunk of our createLLVMModule():
