[LLVMdev] LazyValueInfo.getPredicateAt
Hi, Is it intentional that LazyValueInfo.getPredicateAt doesn't solve for the value and only takes assumptions into account? getPredicateAt gets lattice value from cache using getValueAt call: LVILatticeVal LazyValueInfoCache::getValueAt(Value *V, Instruction *CxtI) { ... LVILatticeVal Result; mergeAssumeBlockValueConstantRange(V, Result, CxtI); ... return Result; } Other
