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
