    In addition to what Steven suggested, you might also consider
    LLVM (http://llvm.cs.uiuc.edu). This is also a very well
    documented and powerful IR. Moreover, unlike Open64, the
    system built on top of it (compiler, dynamic optimizer, VM, etc)
    is also well documented with a simple, hygienic design.
