llvm dev - Apr 2013 - [LLVMdev] inserting a function into a module

I'm looking for an example of how to insert a new function into a module.

I have a module pass that needs to create some new functions.

Grep any LLVM code for Function::Create

For example:

https://hpcforge.org/scm/viewvc.php/*checkout*/trunk/src/runtime/Wrappers.cpp?root=kernelgen

        // The host call launcher prototype to be added
        // to entire module.
        Module* m = call->getParent()->getParent()->getParent();
        Function* hostcall = m->getFunction("kernelgen_hostcall");
        if (!hostcall)
                hostcall = Function::Create(
                        TypeBuilder<void(types::i<8>*,
types::i<64>,
                                types::i<64>, types::i<32>*),
true>::get(context),
                        GlobalValue::ExternalLinkage,
"kernelgen_hostcall",
m);

Your query should be adequately covered by:

You'll create a function declaration (i.e., an empty function) and then 
add basic blocks to it.

I believe this code from SAFECode 
(http://llvm.org/viewvc/llvm-project/safecode/branches/release_32/lib/OptimizeChecks/InlineFastChecks.cpp?revision=168085&view=markup)
may provide an example (caveat: it works with LLVM 3.2).
