// TFLITE_DEPRECATED()
//
// Duplicated from absl/base/macros.h to avoid pulling in that library.
// Marks a deprecated class, struct, enum, function, method and variable
// declarations. The macro argument is used as a custom diagnostic message (e.g.
// suggestion of a better alternative).
//
// Example:
//
//   class TFLITE_DEPRECATED("Use Bar instead") Foo {...};
//   TFLITE_DEPRECATED("Use Baz instead") void Bar() {...}
//
// Every usage of a deprecated entity will trigger a warning when compiled with
// clang's `-Wdeprecated-declarations` option. This option is turned off by
// default, but the warnings will be reported by clang-tidy.
