--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
How does it work for 'double' vs. 'long double' themselves?
<1><32>: Abbrev Number: 3 (DW_TAG_base_type)
<33> DW_AT_byte_size : 16
<34> DW_AT_encoding : 4 (float)
<35> DW_AT_name : (indirect string, offset: 0x60): long double
so if it's not distinguishable via DW_AT_byte_size you look into
DW_AT_name as well? So it looks like doing the same for _Complex long double
is perfectly in line?
