Exemplos de BranchProbabilityInfo em C++ (Cpp)

Exemplo n.º 1

Arquivo: OptimizationDiagnosticInfo.cpp Projeto: Leedehai/llvm

OptimizationRemarkEmitter::OptimizationRemarkEmitter(const Function *F)
    : F(F), BFI(nullptr) {
  if (!F->getContext().getDiagnosticHotnessRequested())
    return;

  // First create a dominator tree.
  DominatorTree DT;
  DT.recalculate(*const_cast<Function *>(F));

  // Generate LoopInfo from it.
  LoopInfo LI;
  LI.analyze(DT);

  // Then compute BranchProbabilityInfo.
  BranchProbabilityInfo BPI;
  BPI.calculate(*F, LI);

  // Finally compute BFI.
  OwnedBFI = llvm::make_unique<BlockFrequencyInfo>(*F, BPI, LI);
  BFI = OwnedBFI.get();
}
