// A standard usage looks like:
//
//      AT_DISPATCH_ALL_TYPES(self.scalar_type(), "op_name", [&] {
//          // Your code here, with 'scalar_t' now defined to
//          // be the dtype in question
//      })
//
// There are many variations of this macro, so it's important to
// understand exactly /which/ dtypes you want to get instantiated, as
// well as what the "default" set is.
//
// The default set of dtypes that are instantiated (e.g., by
// AT_DISPATCH_ALL_TYPES) are floating point types (float, double),
// and integral types (int32_t, int64_t, int16_t, int8_t, uint8_t),
// but NOT booleans (bool), half-precision floats (Half) or
// complex number (c10::complex<float>, c10::complex<double>).
// This "cut" is somewhat historical (the default types are the
// ones that TH historically supported), but it also reflects the
// fact that the non-default types are "poorly" behaved (booleans
// are NOT integers mod 2, half precision operations ~essentially
// don't exist on CPU, complex numbers are an experimental application).
//
// Here are the questions you should generally ask to decide which
// dispatch you want:
//
// 1. Is this an integral or floating point specific operation?
//    (If so, you'll want one of the FLOATING or INTEGRAL macros.)
//
// 2. Should half be supported?  (If you're on CPU, the answer is almost
//    definitely no.  If you do want support, use one of the AND_HALF
//    macros)
//
// Much rarer situations:
//
// 3. Should bool be supported?  (You often have to write your kernel
//    differently if arithmetic operations are involved.)  If so,
//    Use AT_DISPATCH_ALL_TYPES_AND along with ScalarType::Bool
//
// 4. Should complex be supported?  The answer is almost always no,
//    unless you are working on "generic" code that should work on
//    all dtypes.
//
// Parameters:
// -----------
//
// 1. The NAME argument is a "tag" that is used to trace and then
//    conditionally compile fragments of the case statements such
//    that the kernel functions are specialized only for the dtypes
//    that are needed. The NAME parameter *must* be a build time
//    cons char* (can't be std::string, etc...)
//
// Please ensure that the NAME is unique for every implementation
// or you run the risk of over-including code for the kernel
// functions. There is no risk of missing out on any code, so
// it's mostly a risk of a Type-2 error, and not a Type-1 error.
//

// NB: the the_type variable is not used, but we have kept it for
// backwards compatibility.  It's probably not used by anyone though;
// but we're just being safe (and it doesn't hurt.)  Note we must
// use it to shut up warnings about unused store.
