I just sent three messages to gcc-patches breaking out the three independent pieces of Zoltan's original patch and explaining each one using my own description of what it fixes and how it fixes the incorrect code generation. I don't know if this is sufficiently thorough. My explanation is more detailed and specific for each hunk. The separate messages should clarify which parts are independent. Thanks, David
