Simon Pilgrim cb0d04c29e [DAG] Add initial SelectionDAG::isGuaranteedNotToBeUndefOrPoison framework (PR51129) ... I've setup the basic framework for the isGuaranteedNotToBeUndefOrPoison call and updated DAGCombiner::visitFREEZE to use it, further Opcodes can be handled when we have test coverage. I'm not aware of any vector test freeze coverage so the DemandedElts (and the Depth) args are not being used yet - but they are in place. SelectionDAG::isGuaranteedNotToBePoison wrappers have also been added. Differential Revision: https://reviews.llvm.org/D106668		2021-07-24 11:36:35 +01:00
