        * tree-ssa-address.c (copy_mem_ref_info): Copy TREE_SIDE_EFFECTS
        and TREE_THIS_VOLATILE.
        (copy_ref_info): Likewise.
        * tree-ssa-operands.c (get_tmr_operands): Check TREE_THIS_VOLATILE.
        * tree.c (build7_stat): Ignore side-effects of all but arg5
        for TARGET_MEM_REF.  Set TREE_THIS_VOLATILE from arg5 of
        TARGET_MEM_REF.

        * gcc.c-torture/compile/pr43614.c: New testcase.
