Detailed Description

This class represents liveness information on block level.

Member Typedef Documentation

ValueSetT

using mlir::LivenessBlockInfo::ValueSetT = Liveness::ValueSetT

A typedef declaration of a value set.

Member Function Documentation

getBlock()

Block* mlir::LivenessBlockInfo::getBlock ( ) const

inline

Returns the underlying block.

getEndOperation()

Operation * LivenessBlockInfo::getEndOperation	(	Value	value,
		Operation *	startOperation
	)		const

Gets the end operation for the given value using the start operation provided (must be referenced in this block).

getStartOperation()

Operation * LivenessBlockInfo::getStartOperation

(

Value

value

)

const

Gets the start operation for the given value. This is the first operation the given value is considered to be live. This could either be the start operation of the current block (in case the value is live-in) or the operation that defines the given value (must be referenced in this block).

Gets the start operation for the given value (must be referenced in this block).

in()

const ValueSetT& mlir::LivenessBlockInfo::in ( ) const

inline

Returns all values that are live at the beginning of the block (unordered).

isLiveIn()

bool LivenessBlockInfo::isLiveIn

(

Value

value

)

const

Returns true if the given value is in the live-in set.

isLiveOut()

bool LivenessBlockInfo::isLiveOut

(

Value

value

)

const

Returns true if the given value is in the live-out set.

out()

const ValueSetT& mlir::LivenessBlockInfo::out ( ) const

inline

Returns all values that are live at the end of the block (unordered).
