Functions

bool llvm::hasProfMD (const Instruction &I)
 Checks if an Instruction has MD_prof Metadata.
 
bool llvm::isBranchWeightMD (const MDNode *ProfileData)
 Checks if an MDNode contains Branch Weight Metadata.
 
bool llvm::hasBranchWeightMD (const Instruction &I)
 Checks if an instructions has Branch Weight Metadata.
 
bool llvm::hasValidBranchWeightMD (const Instruction &I)
 Checks if an instructions has valid Branch Weight Metadata.
 
MDNodellvm::getBranchWeightMDNode (const Instruction &I)
 Get the branch weights metadata node.
 
MDNodellvm::getValidBranchWeightMDNode (const Instruction &I)
 Get the valid branch weights metadata node.
 
bool llvm::extractBranchWeights (const MDNode *ProfileData, SmallVectorImpl< uint32_t > &Weights)
 Extract branch weights from MD_prof metadata.
 
void llvm::extractFromBranchWeightMD (const MDNode *ProfileData, SmallVectorImpl< uint32_t > &Weights)
 Faster version of extractBranchWeights() that skips checks and must only be called with "branch_weights" metadata nodes.
 
bool llvm::extractBranchWeights (const Instruction &I, SmallVectorImpl< uint32_t > &Weights)
 Extract branch weights attatched to an Instruction.
 
bool llvm::extractBranchWeights (const Instruction &I, uint64_t &TrueVal, uint64_t &FalseVal)
 Extract branch weights from a conditional branch or select Instruction.
 
bool llvm::extractProfTotalWeight (const MDNode *ProfileData, uint64_t &TotalWeights)
 Retrieve the total of all weights from MD_prof data.
 
bool llvm::extractProfTotalWeight (const Instruction &I, uint64_t &TotalWeights)
 Retrieve the total of all weights from an instruction.
 
void llvm::setBranchWeights (Instruction &I, ArrayRef< uint32_t > Weights)
 Create a new branch_weights metadata node and add or overwrite a prof metadata reference to instruction I.
