It adds a new overload for reverse_storage_order_for_component_p and sets reversed on the VN IL ops for component and array accesses accordingly. It also compares the reversed reference ops flag on reference lookup. 2021-08-16 Richard Biener <rguenther@suse.de> PR tree-optimization/101925 * tree-ssa-sccvn.c (copy_reference_ops_from_ref): Set reverse on COMPONENT_REF and ARRAY_REF according to what reverse_storage_order_for_component_p does. (vn_reference_eq): Compare reversed on reference ops. (reverse_storage_order_for_component_p): New overload. (vn_reference_lookup_3): Check reverse_storage_order_for_component_p on the reference looked up. * gcc.dg/sso-16.c: New testcase.
