DWARF Version 6 Language and Version Codes
Note: The information on this page is part of the Draft of DWARF Version 6 and is subject to change.
Issue 210419.1
introduced a way to separately specify languages and versions, and 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.
Issue 210514.1 introduced two additional version schemes.
New language codes may be added by submitting a request. See the Public Comment page.
