commit r16-5830-g464fce5a9f3f1591c465020e62bc15c14aa1b2c9 Author: Robin Dapp <[email protected]> Date: Mon Dec 1 17:27:04 2025 +0100 vect: Use loop len in vectorizable_scan_store. On riscv we ICE because we use SELECT_VL for a vectorizable_scan_store that calls vect_get_data_ptr_increment without a loop_lens argument. This patch just gets the loop_lens and passes them along. gcc/ChangeLog: * tree-vect-stmts.cc (vectorizable_scan_store): Pass loop_lens to vect_get_data_ptr_increment.
