I read the relay function attrs code.
namespace attr {
/*! \brief Mark the function as a primitive function. */
constexpr const char* kPrimitive = "Primitive";
/*!
* \brief Indicate the compiler that should be used for building this function.
* When this is unset or set to "default", the default compilation pipeline will be used.
*/
constexpr const char* kCompiler = "Compiler";
/*! \brief Indicate if the function is a closure. */
constexpr const char* kClosure = "Closure";
/*! \brief Store a Var to parameter/Constant mapping on a Function. */
constexpr const char* kParams = "__params__";
/*! \brief Store the unique external symbol for external compilers. */
constexpr const char* kExternalSymbol = "ExternalSymbol";
/*! \brief Mark if the function should be avoided being optimized. */
constexpr const char* kSkipOptimization = "SkipOptimization";
/*! \brief Treat the function as a composite operator. */
constexpr const char* kComposite = "Composite";
/*! \brief Mark the function to be inlined. */
constexpr const char* kInline = "Inline";
/*! \brief Indicate the function was created by the Pattern Partitioning Pass. */
constexpr const char* kPartitionedFromPattern = "PartitionedFromPattern";
/*! \brief Mark the function as only composed of reshape operations. */
constexpr const char* kReshapeOnly = "relay.reshape_only";
} // namespace attr
How does lowerTE pass handle function with above attrs？
I guess LowerTE Pass will invoke schedule to generate TIR code when function with primitive attrs. If a Function marks with Compiler, the Pass will not handle this and just pass down to compiler. When a function will define as Closuer?
