[SPIR/PTX] Divergence analysis for BasicBlocks
Hello, It seems to me that our current DivergenceAnalysis does not save which BasicBlocks may suffer from divergent control. Am I correct? I want to modify our DivergenceAnalysis to add a "bool isControlDivergent(BasicBlock*) const" method and save in the divergence propagator the basicblock that are divergent. I am not sure that is entirely correct, if you have input on that please
