+       * dwarf2out.c (dw_cfi_oprnd_struct): Reduce dw_cfi_reg_num to int.
+       (lookup_cfa_1): Apply data alignment to DW_CFA_def_cfa_offset_sf
+       and DW_CFA_def_cfa_sf.
+       (def_cfa_1): Use DW_CFA_def_cfa_offset_sf with negative values.
+       (dbx_reg_number): Don't assert particular registers here.
+       (based_loc_descr): ... do it here instead.  Fold in ...
+       (eliminate_reg_to_offset): ... this function.
+       (compute_frame_pointer_to_cfa_displacement): Fold in the effects
+       of eliminate_reg_to_offset; use FRAME_POINTER_CFA_OFFSET.
+       * unwind-dw2.c (execute_cfa_program): Apply data align factor
+       to DW_CFA_def_cfa_offset_sf and DW_CFA_def_cfa_sf.
+       * function.c (instantiate_new_reg): Use FRAME_POINTER_CFA_OFFSET.
+       (instantiate_virtual_regs): Likewise.
