--- Comment #6 from Doug Gilmore <doug.gilmore at imgtec dot com> --- > The input to the vectorizer is already bogus: > > _12 = i.0_5 + 536870911; > _13 = global_data.b[_12]; Note that gimple out generated by the front end is already problematic: Before r187042: D.1747 = i.0 + -1; With r187042: D.1747 = i.0 + 536870911; Any idea what the intent of the changes in r187042 that transform signed to unsigned constants? To me, that is the problematic issue.
