--- Comment #10 from Richard Biener <rguenth at gcc dot gnu.org> --- OK, so apart from IVOPTs computing bullshit base objects, it computes "I have see multiple", but tree-ssa-address.cc doesn't even look at that case. Also rewrite_use_address only considers the candidate IV base object, but get_computation_aff relates both candidate and use. In the PR125730 case the use IV has a integer_zero_node base object (multiple base objects). I have pieces of a fix...
