C++ (Cpp) AliasSet::removeFromTracker Examples

Example #1

File: AliasSetTracker.cpp Project: BlakeTriana/clReflect

/// remove - Remove the specified (potentially non-empty) alias set from the
/// tracker.
void AliasSetTracker::remove(AliasSet &AS) {
  // Drop all call sites.
  AS.UnknownInsts.clear();
  
  // Clear the alias set.
  unsigned NumRefs = 0;
  while (!AS.empty()) {
    AliasSet::PointerRec *P = AS.PtrList;

    Value *ValToRemove = P->getValue();
    
    // Unlink and delete entry from the list of values.
    P->eraseFromList();
    
    // Remember how many references need to be dropped.
    ++NumRefs;

    // Finally, remove the entry.
    PointerMap.erase(ValToRemove);
  }
  
  // Stop using the alias set, removing it.
  AS.RefCount -= NumRefs;
  if (AS.RefCount == 0)
    AS.removeFromTracker(*this);
}

Example #2

    // Unlink from the list of values.
    P->second.removeFromList();
    
    // Remember how many references need to be dropped.
    ++NumRefs;

    // Finally, remove the entry.
    Value *Remove = P->first;   // Take a copy because it is invalid to pass
    PointerMap.erase(Remove);   // a reference to the data being erased.
  }
  
  // Stop using the alias set, removing it.
  AS.RefCount -= NumRefs;
