C++ (Cpp) available_to_min_gen Examples

Example #1

File: psYoungGen.cpp Project: 641252154/HotSpot-JVM-Linux-x86-Research

// Return the number of bytes available for resizing down the young
// generation.  This is the minimum of
//      input "bytes"
//      bytes to the minimum young gen size
//      bytes to the size currently being used + some small extra
size_t PSYoungGen::limit_gen_shrink(size_t bytes) {
  // Allow shrinkage into the current eden but keep eden large enough
  // to maintain the minimum young gen size
  bytes = MIN3(bytes, available_to_min_gen(), available_to_live());
  return align_size_down(bytes, virtual_space()->alignment());
}

Example #2

// Return the number of bytes available for resizing down the young
// generation.  This is the minimum of
//      input "bytes"
//      bytes to the minimum young gen size
//      bytes to the size currently being used + some small extra
size_t ASParNewGeneration::limit_gen_shrink (size_t bytes) {
  // Allow shrinkage into the current eden but keep eden large enough
  // to maintain the minimum young gen size
  bytes = MIN3(bytes, available_to_min_gen(), available_to_live());
  return align_size_down(bytes, os::vm_page_size());
