* config/rs6000/rs6000.md (define_attr "maybe_prefixed"): New.
(define_attr "prefixed"): Update initializer.

PR debug/99490
* dwarf2out.c (debug_ranges_dwo_section): New variable.
(DW_RANGES_IDX_SKELETON): Define.
(struct dw_ranges): Add begin_entry and end_entry members.
(DEBUG_DWO_RNGLISTS_SECTION): Define.
(add_ranges_num): Adjust r initializer for addition of *_entry
members.
(add_ranges_by_labels): For -gsplit-dwarf and force_direct,
set idx to DW_RANGES_IDX_SKELETON.
(use_distinct_base_address_for_range): New function.
(index_rnglists): Don't set r->idx if it is equal to
DW_RANGES_IDX_SKELETON. Initialize r->begin_entry and
r->end_entry for -gsplit-dwarf if those will be needed by
output_rnglists.
(output_rnglists): Add DWO argument. If true, switch to
debug_ranges_dwo_section rather than debug_ranges_section.
Adjust l1/l2 label indexes. Only output the offset table when
dwo is true and don't include in there the skeleton range
entry if present. For -gsplit-dwarf, skip ranges that belong
to the other rnglists section. Change return type from void
to bool and return true if there are any range entries for
the other section. For dwarf_split_debug_info use
DW_RLE_startx_endx, DW_RLE_startx_length and DW_RLE_base_addressx
entries instead of DW_RLE_start_end, DW_RLE_start_length and
DW_RLE_base_address. Use use_distinct_base_address_for_range.
(init_sections_and_labels): Initialize debug_ranges_dwo_section
if -gsplit-dwarf and DWARF >= 5. Adjust ranges_section_label
and range_base_label indexes.
(dwarf2out_finish): Call index_rnglists earlier before finalizing
.debug_addr. Never emit DW_AT_rnglists_base attribute. For
-gsplit-dwarf and DWARF >= 5 call output_rnglists up to twice
with different dwo arguments.
(dwarf2out_c_finalize): Clear debug_ranges_dwo_section.
