--- Comment #36 from Jeffrey A. Law <law at redhat dot com> --- WRT the division removal. That seems so profitable that a slight increase in codesize is warranted. So if we fix the other issue and the source of the remaining codesize regressions is the removal of the division, I would consider this BZ resolved.
