rtl.def (DEBUG_IMPLICIT_PTR): New rtl code.
* rtl.def (DEBUG_IMPLICIT_PTR): New rtl code. * rtl.h (DEBUG_IMPLICIT_PTR_DECL): Define. * rtl.c (rtx_equal_p_cb, rtx_equal_p): Handle DEBUG_IMPLICIT_PTR. * print-rtl.c (print_rtx): Likewise. * cselib.c (rtx_equal_for_cselib_p, cselib_hash_rtx): Likewise. * cfgexpand.c (expand_debug_expr): Generate DEBUG_IMPLICIT_PTR for ADDR_EXPR with non-addressable object. * dwarf2out.c (enum dw_val_class): Add dw_val_class_decl_ref. (struct dw_val_struct): Add v.val_decl_ref. (dwarf_stack_op_name, output_loc_operands, output_loc_operands_raw): Handle DW_OP_GNU_implicit_pointer. (size_of_loc_descr): Likewise. Fix up DW_OP_call_ref size. (get_ref_die_offset_label): New function. (implicit_ptr_descriptor): New function. (mem_loc_descriptor): Handle DEBUG_IMPLICIT_PTR. (loc_descriptor): Likewise. (gen_variable_die): Put even definitions into decl_die_table. (resolve_addr_in_expr): Resolve still unresolved DW_OP_GNU_implicit_pointer operands, if it can't be resolved return false. (dwarf2out_finish): Call output_location_lists after outputting .debug_info and .debug_abbrev instead of before. * dwarf2.h (DW_OP_GNU_implicit_pointer): New. 2010-09-09 Roland McGrath <roland@redhat.com> * dwarf2out.c (DWARF_REF_SIZE): Define. (size_of_loc_descr): Use it for DW_OP_call_ref. From-SVN: r164050
