// Update these tests once support for DW_LANG_C_plus_plus_17/20 is added - it's
// a complicated tradeoff. The language codes are already published/blessed by
// the DWARF committee, but haven't been released in a published standard yet,
// so consumers might not be ready for these codes & could regress functionality
// (because they wouldn't be able to identify that the language was C++). The
// DWARFv6 language encoding, separating language from language version, would
// remove this problem/not require new codes for new language versions and make
// it possible to identify the base language irrespective of the version.
