Hi @cwabbott, 
This commit causes a GPU hang on amdvlk in one test, due to the missing "done" bit on the normal export. I think in the attached case the patch incorrectly classifies the export as being in an infinite loop.F11390737: before_AMDGPUUnifyDivergentExitNodes.ll <https://reviews.llvm.org/F11390737>
