C++ (Cpp) SegmentIter::insert Beispiele

Beispiel #1

Datei: LiveIntervalUnion.cpp Projekt: mapu/llvm

// Merge a LiveInterval's segments. Guarantee no overlaps.
void LiveIntervalUnion::unify(LiveInterval &VirtReg) {
  if (VirtReg.empty())
    return;
  ++Tag;

  // Insert each of the virtual register's live segments into the map.
  LiveInterval::iterator RegPos = VirtReg.begin();
  LiveInterval::iterator RegEnd = VirtReg.end();
  SegmentIter SegPos = Segments.find(RegPos->start);

  while (SegPos.valid()) {
    SegPos.insert(RegPos->start, RegPos->end, &VirtReg);
    if (++RegPos == RegEnd)
      return;
    SegPos.advanceTo(RegPos->start);
  }

  // We have reached the end of Segments, so it is no longer necessary to search
  // for the insertion position.
  // It is faster to insert the end first.
  --RegEnd;
  SegPos.insert(RegEnd->start, RegEnd->end, &VirtReg);
  for (; RegPos != RegEnd; ++RegPos, ++SegPos)
    SegPos.insert(RegPos->start, RegPos->end, &VirtReg);
}
