Member Function Documentation

Create()

static PassContext tvm::transform::PassContext::Create ( )

static

Construct a PassContext containing the default configurations.

Returns

The new PassContext.

Current()

static PassContext tvm::transform::PassContext::Current ( )

static

Get the default pass context in the current scope.

Returns

The pass context.

InstrumentAfterPass()

void tvm::transform::PassContext::InstrumentAfterPass	(	const IRModule &	mod,
		const PassInfo &	info
	)		const

Call instrument implementations callbacks after a pass run. The callbacks are called in order, and if one raises an exception, the rest will not be called.

Parameters

mod	The module that an optimization pass runs on.
info	The pass information.

InstrumentBeforePass()

bool tvm::transform::PassContext::InstrumentBeforePass	(	const IRModule &	mod,
		const PassInfo &	info
	)		const

Call instrument implementations' callbacks before a pass run. The callbacks are called in order, and if one raises an exception, the rest will not be called.

Parameters

mod	The module that an optimization pass runs on.
info	The pass information.

Returns

false: the pass is skipped; true: the pass runs.

InstrumentEnterPassContext()

void tvm::transform::PassContext::InstrumentEnterPassContext

(

)

Call instrument implementations' callbacks when entering PassContext. The callbacks are called in order, and if one raises an exception, the rest will not be called.

InstrumentExitPassContext()

void tvm::transform::PassContext::InstrumentExitPassContext

(

)

Call instrument implementations' callbacks when exiting PassContext. The callbacks are called in order, and if one raises an exception, the rest will not be called.

ListConfigs()

static ffi::Map<ffi::String, ffi::Map<ffi::String, ffi::String> > tvm::transform::PassContext::ListConfigs ( )

static

Get all supported configuration names and metadata, registered within the PassContext.

Returns

Map indexed by the config name, pointing to the metadata map as key-value

operator->() [1/2]

PassContextNode* tvm::transform::PassContext::operator-> ( )

inline

mutable accessor.

Returns

mutable access pointer.

operator->() [2/2]

const PassContextNode* tvm::transform::PassContext::operator-> ( ) const

inline

const accessor.

Returns

const access pointer.

PassEnabled()

bool tvm::transform::PassContext::PassEnabled

(

const PassInfo &

info

)

const

Check whether a pass is enabled.

Parameters

info	The pass information.

Returns

true if the pass is enabled. Otherwise, false.

RegisterConfigOption()

template<typename ValueType >

static int32_t tvm::transform::PassContext::RegisterConfigOption ( const char *  key )

inlinestatic

Register a valid configuration option and its ValueType for validation.

Parameters

key	The configuration key.

Template Parameters

ValueType

The value type to be registered
