Constructor & Destructor Documentation

Target() [1/4]

tvm::Target::Target ( std::nullptr_t  )

inlineexplicit

Construct a null Target.

Target() [2/4]

tvm::Target::Target ( const String &  tag_or_config_or_target_str )

explicit

Construct a Target given a string.

Parameters

tag_or_config_or_target_str

the string to parse for target

Target() [3/4]

tvm::Target::Target ( const Map< String, ObjectRef > &  config )

explicit

Construct a Target using a JSON-like configuration.

Parameters

config

The JSON-like configuration for target

Target() [4/4]

tvm::Target::Target ( Target  target, Target  host  )

explicit

Construct a Target given target and host.

Parameters

target	The Target typed object with host field undefined for target
host	The Target typed object for target host

Member Function Documentation

Current()

static tvm::Target tvm::Target::Current ( bool  allow_not_defined = true )

static

Get the current target context from thread local storage.

Parameters

allow_not_defined

If the context stack is empty and this is set to true, an undefined Target will be returned. Otherwise, an empty context stack will cause a runtime error.

Returns

The target that is the current context. The target may not be defined if allow_not_defined is true.

TVM_DEFINE_OBJECT_REF_METHODS()

tvm::Target::TVM_DEFINE_OBJECT_REF_METHODS	(	Target	,
		ObjectRef	,
		TargetNode
	)

WithHost()

static Target tvm::Target::WithHost ( const Target &  target, const Target &  host  )

static

Create a new Target object with given target (w.o host) and target host.

Parameters

target	The current Target typed object target, with or without host field.
host	The given Target typed object target host

Returns

The new Target object with the given target and host field of given host.

WithoutHost()

Target tvm::Target::WithoutHost

(

)

const

Returns

The target with the host stripped out
