        * tree.h (fndecl_built_in_p): Use fndecl_built_in_p instead of
        DECL_BUILT_IN in comment.  Remove redundant ()s around return
        argument.
        * tree.c (free_lang_data_in_decl): Check if var is FUNCTION_DECL
        before calling fndecl_built_in_p.
        * gimple-fold.c (gimple_fold_stmt_to_constant_1): Check if
        TREE_OPERAND (fn, 0) is a FUNCTION_DECL before calling
        fndecl_built_in_p on it.
lto/
        * lto-lang.c (handle_const_attribute): Don't call fndecl_built_in_p
        on *node that is not FUNCTION_DECL.
testsuite/
        * gcc.c-torture/compile/pr92231.c: New test.
