| // 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. |
