  "message": "c++: Don\u0027t support auto{x} and auto(x) for C++ \u003c 23 in SFINAE contexts [PR120685]\n\nThe following testcase ICEs in C++ 20 and older, because during\ndiagnostics dump_template_bindings attempts to tsubst with tf_none\nsomething and we try to emit a pedwarn during that.\nWhile the pedwarn could be just guarded with if (complain \u0026 tf_warning),\nI thought we shouldn\u0027t support extensions for tf_none and should\ninstead return error_mark_node.\n\nThe following patch does that.\n\nThis is a backport version which instead of not supporting it just\ndoesn\u0027t emit the pedwarn in SFINAE contexts for C++ \u003c 23 but still\nsupports it.\n\n2026-02-17  Jakub Jelinek  \u003cjakub@redhat.com\u003e\n\n\tPR c++/120685\n\t* typeck2.cc (build_functional_cast_1): For C++23 auto(x)\n\twithout tf_warning or tf_error return error_mark_node instead of\n\temitting pedwarn and handling it.\n\t* semantics.cc (finish_compound_literal): Similarly for C++26\n\tauto{x}.\n\n\t* g++.dg/cpp23/auto-fncast19.C: New test.\n\n(cherry picked from commit f7efb7e62ac96c082ff72549d9b3789f5c955efe)\n",
