Ejemplos de HashOfArrayOfPCs en C++ (Cpp)

Ejemplo n.º 1

Archivo: FuzzerLoop.cpp Proyecto: stevedrake/llvm

// Experimental.
// Fuly reset the current coverage state, run a single unit,
// compute a hash function from the full coverage set,
// return non-zero if the hash value is new.
// This produces tons of new units and as is it's only suitable for small tests,
// e.g. test/FullCoverageSetTest.cpp. FIXME: make it scale.
size_t Fuzzer::RunOneMaximizeFullCoverageSet(const Unit &U) {
  __sanitizer_reset_coverage();
  ExecuteCallback(U);
  uintptr_t *PCs;
  uintptr_t NumPCs =__sanitizer_get_coverage_guards(&PCs);
  if (FullCoverageSets.insert(HashOfArrayOfPCs(PCs, NumPCs)).second)
    return FullCoverageSets.size();
  return 0;
