Detailed Description

If-Conversion Transformation.

The If-Conversion transformation converts gamma outputs to select operations iff:

1. A gamma node has only two subregions
2. The value in every subregion that leads to the gamma output are only routed through the subregion.

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.
