--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think for the integer issue there's an exact dup.
Time to add a meta-bug linking all of them? All of the issues really point to
the same very fundamental issue - provenance does not affect the actual value
and since optimizing compilers track value equivalence provenance gets
messed up.
provenance is a dead end.
