Hi!
output_view_list_offset does:
if (dwarf_split_debug_info)
dw2_asm_output_delta (DWARF_OFFSET_SIZE, sym, loc_section_label,
"%s", dwarf_attr_name (a->dw_attr));
else
dw2_asm_output_offset (DWARF_OFFSET_SIZE, sym, debug_loc_section,
"%s", dwarf_attr_name (a->dw_attr));
while output_loc_list_offset does:
if (!dwarf_split_debug_info)
dw2_asm_output_offset (DWARF_OFFSET_SIZE, sym, debug_loc_section,
"%s", dwarf_attr_name (a->dw_attr));
else if (dwarf_version >= 5)
{
gcc_assert (AT_loc_list (a)->num_assigned);
dw2_asm_output_data_uleb128 (AT_loc_list (a)->hash, "%s (%s)",
dwarf_attr_name (a->dw_attr),
sym);
}
else
dw2_asm_output_delta (DWARF_OFFSET_SIZE, sym, loc_section_label,
"%s", dwarf_attr_name (a->dw_attr));
but both size_of_die and value_format handle both the same as loc_list,
so for -gdwarf-5 -gsplit-dwarf we just ICE, as e.g. AT_loc_list is not
valid on a view list.
Assuming output_view_list_offset is correct, the following patch adjusts
size_of_die/value_format accordingly.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

* dwarf2out.c (size_of_die): For dw_val_class_view_list always use
DWARF_OFFSET_SIZE.
(value_format): For dw_val_class_view_list never use DW_FORM_loclistx.
