DWARF Version 6 Language and Version Codes
Issue 210419.1
introduced a way to separately specify languages and versions which is
expected to be adopted for DWARF Version 6.
As described in the proposal, each supported language has a specified
value for DW_AT_language_name and each version of that language has a
unique DW_AT_language_version.
New language codes and version codes may be requested by submitting a request on the Public Comment page.
