commit r17-465-ga9883211f8891a3cb5966cbe2fbec35e25631d83 Author: Richard Biener <[email protected]> Date: Tue May 12 10:40:56 2026 +0200 Avoid setting ls_type when unused The following avoids setting the ls_type on loads/stores when that type isn't used. * tree-vect-stmts.cc (get_load_store_type): Pass temporary to vect_use_grouped_gather, only set ls_type when that succeeded.
