+       * fold-const.c (try_move_mult_to_index): Handle INTEGER_CST
+       and generic summands for char* as s * delta, too, folding &a[i]
+       CODE x to &a[i CODE x/s].  Use tree_int_cst_equal
+       for comparison of steps.  Convert types for index addition.
+       (fold_binary): Adjust the callers to always dispatch to
+       try_move_mult_to_index.
+       * tree-ssa-propagate.c (set_rhs): Avoid setting rhs to
+       expr with non-gimple ARRAY_REF offset.

        * fold-const.c (fold_indirect_ref_1): Avoid removing
