This may be a breaking change for consumers if they're trying to detect if code is C or C++, since it'll start using new codes that they may not be ready to recognize, in which case they may fall back to non-C handling. This caused regressions due to PS4 having a different default for C language version than other targets. Those tests were adapted to be relaxed about which C version is used. This reapplies commit 3c312e48f325c1b1ee11404ee6cfa08ee00037b0 Which was reverted by commit 6ab6085c77ef9bcdabf842342f63fba4291791a4. Differential Revision: https://reviews.llvm.org/D138597

// 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.
