using | ValT = Value * |
using | PhiT = PHINode |
using | BlkSucc_iterator = succ_iterator |
Static Public Member Functions | |
static BlkSucc_iterator | BlkSucc_begin (BlkT *BB) |
static BlkSucc_iterator | BlkSucc_end (BlkT *BB) |
static PHI_iterator | PHI_begin (PhiT *PHI) |
static PHI_iterator | PHI_end (PhiT *PHI) |
static void | FindPredecessorBlocks (BasicBlock *BB, SmallVectorImpl< BasicBlock * > *Preds) |
FindPredecessorBlocks - Put the predecessors of Info->BB into the Preds vector, set Info->NumPreds, and allocate space in Info->Preds. | |
static Value * | GetUndefVal (BasicBlock *BB, SSAUpdater *Updater) |
GetUndefVal - Get an undefined value of the same type as the value being handled. | |
static Value * | CreateEmptyPHI (BasicBlock *BB, unsigned NumPreds, SSAUpdater *Updater) |
CreateEmptyPHI - Create a new PHI instruction in the specified block. | |
static void | AddPHIOperand (PHINode *PHI, Value *Val, BasicBlock *Pred) |
AddPHIOperand - Add the specified value as an operand of the PHI for the specified predecessor block. | |
static PHINode * | ValueIsPHI (Value *Val, SSAUpdater *Updater) |
ValueIsPHI - Check if a value is a PHI. | |
static PHINode * | ValueIsNewPHI (Value *Val, SSAUpdater *Updater) |
ValueIsNewPHI - Like ValueIsPHI but also check if the PHI has no source operands, i.e., it was just added. | |
static Value * | GetPHIValue (PHINode *PHI) |
GetPHIValue - For the specified PHI instruction, return the value that it defines. | |
