Function Documentation

pruneUnusedOps() [1/2]

void circt::reduce::pruneUnusedOps	(	Operation *	initialOp,
		Reduction &	reduction
	)

Starting at the given op, traverse through it and its operands and erase operations that have no more uses.

pruneUnusedOps() [2/2]

void circt::reduce::pruneUnusedOps	(	SmallVectorImpl< Operation * > &	worklist,
		Reduction &	reduction
	)

Starting from an initial worklist of operations, traverse through it and its operands and erase operations that have no more uses.

This is useful when there are repeated calls to pruneUnusedOp that want to delete the same operations.
