        * dwarf2out.h (dwarf_frame_regnum): Remove.
        * dwarf2out.c (based_loc_descr): Revert last change.  Initialize regno
        earlier from DWARF_FRAME_REGNUM.  Never use dbx_reg_number.
        * dwarf2cfi.c (dw_stack_pointer_regnum, dw_frame_pointer_regnum): New.
        (execute_dwarf2_frame): Initialize them.
        (DW_STACK_POINTER_REGNUM, DW_FRAME_POINTER_REGNUM): Remove; replace
        users of the macros with the variables.
        (expand_builtin_dwarf_sp_column): Revert last change.
        (expand_builtin_init_dwarf_reg_sizes): Likewise.  Compute the
        result of DWARF_FRAME_REGNUM into a local variable.
