        * emit-rtl.c (set_mem_attributes_minus_bitpos): Look through
        component-like references for setting MEM_NOTRAP_P.

        PR rtl-opt/23601
        * reload1.c (reload): Set MEM_NOTRAP_P in spill slots.
        (fixup_eh_region_note): New.
        (reload_as_needed): Call it.
        (fixup_abnormal_edges): Allow all throwing insns to be deleted;
        don't call find_many_sub_basic_blocks; call verify_flow_info.
        * function.c (assign_stack_local_1): Set MEM_NOTRAP_P.
        (keep_stack_depressed): Likewise.
        (assign_stack_temp_for_type): Likewise; use adjust_address_nv.
