This arg is only supported by CLang 17 or GCC 12 though, both of which are beyond our current min versions. This series bumps both CLang and GCC to enable this. The GCC bump is technically something we shouldn't do per our platform support matrix, as the system compiler in our targetted releases of NetBSD, remains GCC 10.4 This series considers it reasonable to bend the rules slightly, as NetBSD does have new enough CLang, and also ships newer GCC as non-system compilers. Also historically the macOS XCode versions reported by clang did not appear to align with upstream CLang versions so we checked versions separately for macOS. With this set of patches we happen to end up on 17.0 for both upstream CLang and macOS Clang, and this makes me wonder if we can rely on aligned versions going forward ? Latest XCode 26.6 apparently reports clang 21.0.0 which appears to be a match for a modern llvm release. Daniel P.
