        of the associated gen_rtx_* call.
        * caller-save.c (init_caller_save): Likewise.
        * combine.c (find_split_point, make_extraction): Likewise.
        (make_compound_operation): Likewise.
        * dwarf2out.c (mem_loc_descriptor): Likewise.
        * explow.c (plus_constant, probe_stack_range): Likewise.
        * expmed.c (expand_mult_const): Likewise.

        * var-tracking.c (adjust_mems): Likewise.
        * modulo-sched.c (sms_schedule): Likewise, but use gen_rtx_GT
        rather than gen_rtx_fmt_ee.
