Note that a new DWARF5 languge code for DW_LANG_C_plus_plus_23 was<br>
added: <a href="https://dwarfstd.org/issues/240616.1.html" rel="noreferrer" target="_blank">https://dwarfstd.org/issues/240616.1.html</a> and several others<br>
were added just last month <a href="https://dwarfstd.org/languages.html" rel="noreferrer" target="_blank">https://dwarfstd.org/languages.html</a><br>
<br>
But you are right we could just adopt the proposed DWARF6<br>
DW_AT_language_name/version attributes, which is more flexible.<br>
Question is if we think they are already "stable".<br>
<a href="https://dwarfstd.org/languages-v6.html" rel="noreferrer" target="_blank">https://dwarfstd.org/languages-v6.html</a> says "The information on this<br>
page is part of the Draft of DWARF Version 6 and is subject to change."<br>
<br>
Cheers,<br>
