This is the third patch in the series of patches to fix constant math.
this one changes some predicates at the rtl level to use the new
predicate CONST_SCALAR_INT_P.
I did not include a few that were tightly intertwined with other changes.
Not all of these changes are strictly mechanical. Richard, when
reviewing this had me make additional changes to remove what he thought
were latent bugs at the rtl level. However, it appears that the bugs
were not latent. I do not know what is going on here but i am smart
enough to not look a gift horse in the mouth.
All of this was done on the same machine with no changes and identical
configs. It is an x86-64 with ubuntu 12-4.
ok for commit?
in the logs below, gbBaseline is a trunk from friday and the gbWide is
the same revision but with my patches. Some of this like
gfortran.dg/pr32627 is obviously flutter, but the rest does not appear
to be.
