Detailed Description

Remove invariant values from gamma, theta, and lambda nodes.

FIXME: This entire transformation can be expressed using llvm::InvariantValueRedirection and llvm::UnusedStateRemoval, and should be replaced by them. The llvm::UnusedStateRemoval would need to be extended to remove unused state edges in lambda nodes though.

overridevirtual

Perform RVSDG transformation.

Note

This method is expected to be called multiple times. An implementation is required to reset the objects' internal state to ensure correct behavior after every invocation.

Parameters

module	RVSDG module the transformation is performed on.
statisticsCollector	Statistics collector for collecting transformation statistics.

Implements jlm::rvsdg::Transformation.
