URL: https://github.com/llvm/llvm-project/commit/a02ee2f6ff2e806c69851182fd6649338020dcae DIFF: https://github.com/llvm/llvm-project/commit/a02ee2f6ff2e806c69851182fd6649338020dcae.diff LOG: [Clang] Define __cpp_pack_indexing (#101956) Following the discussion on #101448 this defines `__cpp_pack_indexing`. Since pack indexing is currently supported in all language modes, the feature test macro is also defined in all language modes.
