Member Function Documentation

◆ Export()

Map<String, ObjectRef> tvm::TargetNode::Export ( ) const

Returns: Export target to JSON-like configuration

◆ GetAttr() [1/2]

template<typename TObjectRef >

Optional<TObjectRef> tvm::TargetNode::GetAttr	(	const std::string &	attr_key,
		Optional< TObjectRef >	default_value = `Optional<TObjectRef>(nullptr)`
	)		const

inline

Get an entry from attrs of the target.

Template Parameters

TObjectRef Type of the attribute

Parameters

attr_key	The name of the attribute key
default_value	The value returned if the key is not present

Returns: An optional, NullOpt if not found, otherwise the value found

◆ GetAttr() [2/2]

template<typename TObjectRef >

Optional<TObjectRef> tvm::TargetNode::GetAttr	(	const std::string &	attr_key,
		TObjectRef	default_value
	)		const

inline

Get an entry from attrs of the target.

Template Parameters

TObjectRef Type of the attribute

Parameters

attr_key	The name of the attribute key
default_value	The value returned if the key is not present

Returns: An optional, NullOpt if not found, otherwise the value found

◆ GetHost()

Optional<Target> tvm::TargetNode::GetHost ( ) const

Returns: The Optional<Target> typed target host of the TargetNode

◆ GetKeys()

std::vector<std::string> tvm::TargetNode::GetKeys ( ) const

Get the keys for this target as a vector of string.

◆ GetLibs()

std::unordered_set<std::string> tvm::TargetNode::GetLibs ( ) const

Get the keys for this target as an unordered_set of string.

◆ SEqualReduce()

bool tvm::TargetNode::SEqualReduce	(	const TargetNode *	other,
		SEqualReducer	equal
	)		const

◆ SHashReduce()

void tvm::TargetNode::SHashReduce ( SHashReducer hash_reduce ) const

◆ str()

const std::string& tvm::TargetNode::str ( ) const

The raw string representation of the target.

Returns: the full device string to pass to codegen::Build

Note: It will be deprecated after the Target RFC is fully landed.

◆ ToDebugString()

String tvm::TargetNode::ToDebugString ( ) const

Returns a human readable representation of Target which includes all fields, especially the host. Useful for diagnostic messages and debugging.

TODO(mbs): The ReprPrinter version should perhaps switch to this form, however currently code depends on str() and << being the same.

◆ TVM_DECLARE_FINAL_OBJECT_INFO()

tvm::TargetNode::TVM_DECLARE_FINAL_OBJECT_INFO	(	TargetNode	,
		Object
	)

◆ VisitAttrs()

void tvm::TargetNode::VisitAttrs ( AttrVisitor * v )

inline
