// Macros to apply another macro to lists of supported types.  If you change
// the lists of types, please also update the list in types.cc.

// See example uses of these macros in core/ops.

//
// Each of these TF_CALL_XXX_TYPES(m) macros invokes the macro "m" multiple
// times by passing each invocation a data type supported by TensorFlow.
//
// The different variations pass different subsets of the types.
// TF_CALL_ALL_TYPES(m) applied "m" to all types supported by TensorFlow.
// The set of types depends on the compilation platform.
//.
// This can be used to register a different template instantiation of
// an OpKernel for different signatures, e.g.:
