dwarf2out.c (dw_cfi_oprnd_struct): Reduce dw_cfi_reg_num to int.
* 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. * var-tracking.c (adjust_stack_reference): Likewise. * doc/tm.texi (FRAME_POINTER_CFA_OFFSET): New. From-SVN: r107154
