Subject: whole program optimization examples?

Hello, I was wondering if there is an example list somewhere of whole program optimizations done by LLVM based compilers? I'm only familiar with method-level optimizations, and I'm being told wpo can deliver many great speedups. My language is currently staticly typed JIT based and uses the JVM, and I want to move it over to LLVM so that I can have options where it can be ahead of time compiled as well. I'm hearing bad things about LLVM's JIT capabilities -- specifically that writing your own GC is going to be a pain. Anyways, sort of diverged there, but still looking for WPO examples! Hayden.
