At -O0 gcc puts absolutely no effort into generating optimal code.
It's not generally all that interesting to ask why the -O0 code is
bad. It is normally just because there is some general optimizer
which will improve it, but that optimizer is not run at -O0.
Please feel free to ask about generated code at -O1 or higher.
