--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
The LC PHI node is missing from the graphite code. This is because the arg
became an invariant which we fail to remap. SCEV cprop would have got rid of
this in
the original loop avoiding this issue.
We never translate the LC PHI nodes of the inner loop so we don't pick up
their "copyness" _79 -> _5 -> _2 where we translated _2 to _33 but not
any of the others (_5 is missing, a LC PHI node of the inner loop).
I'm not sure where to start looking. Surely the issue is not too severe
as SCEV cprop fixes up things for us.
