================
Comment at: lib/Frontend/CompilerInvocation.cpp:2593-2596
+  // Enable [[]] attributes in C++11 and C2x by default.
+  Opts.DoubleSquareBracketAttributes = Args.hasFlag(
+      OPT_fdouble_square_bracket_attributes,
+      OPT_fno_double_square_bracket_attributes, Opts.CPlusPlus11 || Opts.C2x);
----------------
(We get this wrong in a bunch of other places, but...)

The default from the language mode should be set by `setLangDefault`, and here we should override it if suitable flags are set.
