* dwarf2out.h (enum dw_val_class): Add dw_val_class_loclistsptr.
* dwarf2out.c (struct dw_loc_list_struct): Change emitted field
from bool to 1-bit uchar bitfield. Add num_assigned and
offset_emitted bitfields.
(dw_val_equal_p): Compare v.val_lbl_id rather than v.val_unsigned
for dw_val_class_lineptr and dw_val_class_macptr. Handle
dw_val_class_loclistsptr.
(new_addr_loc_descr): Fix up formatting.
(DEBUG_LOCLISTS_SECTION, DEBUG_DWO_LOCLISTS_SECTION): Define.
(add_AT_low_high_pc): Fix up formatting.
(add_AT_loclistsptr): New function.
(AT_lbl): Allow dw_val_class_loclistsptr.
(print_dw_val, attr_checksum, attr_checksum_ordered, same_dw_val_p):
Handle dw_val_class_loclistsptr.
(loc_list_idx): New variable.
(output_loclists_offsets, assign_location_list_indexes): New
functions.
(size_of_die): For dw_val_class_loc_list -gsplit-dwarf -gdwarf-5
add size_of_uleb128 of the index. Drop never used
dwarf_split_debug_info AT_index handling. Handle
dw_val_class_loclistsptr.
(value_format): Return DW_FORM_loclistsx for dw_val_class_loc_list
if -gsplit-dwarf -gdwarf-5. Handle dw_val_class_loclistsptr.
(output_loc_list): Handle DWARF 5 .debug_loclists* format.
(output_loc_list_offset): Handle -gsplit-dwarf -gdwarf-5
DW_FORM_loclistx indexes.
(output_attr_index_or_value): Fix up formatting. Don't handle
dw_val_class_loc_list here.
(output_die): Formatting fixes. Handle dw_val_class_loclistsptr.
For dw_val_class_loc_list call output_loc_list_offset rather than
output_attr_index_or_value.
(init_sections_and_labels): For -gdwarf-5 use .debug_loclists
or .debug_loclists.dwo section name for debug_loc_section.
(resolve_addr_in_expr): Formatting fix.
(index_location_lists): Likewise.
(dwarf2out_finish): If there are any location lists, for
-gsplit-dwarf -gdwarf-5 add DW_AT_loclists_base attribute. Call
index_location_lists only if have_location_lists. Call
assign_location_list_indexes for -gsplit-dwarf -gdwarf-5. Emit
.debug_loclists{,.dwo} section header for -gdwarf-5, for -gdwarf-5
-gsplit-dwarf also emit offset table.
