bool ExtractBridgeInfo::preorder ( const IR::P4Program * program )

override

TODO: some code duplication with extract_mau_pipe, needs to refactor ParseTna to provide a mechanism to iterate directly on TNA pipelines.

SimplifyReferences passes are fixup passes that modifies the visited IR tree. Unfortunately, the modifications by simplifyReferences will transform IR tree towards the backend IR, which means we can no longer run typeCheck pass after applying simplifyReferences to the frontend IR.
