Bingo, it does help!  Thanks Chris!  However, I'm with Aaron on where this
belongs, your link above really should be integrated into or at least an
addendum to the IR Language Reference,

http://llvm.cs.uiuc.edu/docs/LangRef.html

unless you're keeping it out of the official IR docs for now because you
will/might handle this more directly or differently in a future revision of
the IR.  If that's the case then the IR Lang Ref should at least for now
provide a link to the above from within itself, IMHO.  In any case,
thanks! :)
