示例1: GCTraceTime
void GenMarkSweep::mark_sweep_phase2() {
// Now all live objects are marked, compute the new object addresses.
// It is imperative that we traverse perm_gen LAST. If dead space is
// allowed a range of dead object may get overwritten by a dead int
// array. If perm_gen is not traversed last a Klass* may get
// overwritten. This is fine since it is dead, but if the class has dead
// instances we have to skip them, and in order to find their size we
// need the Klass*!
//
// It is not required that we traverse spaces in the same order in
// phase2, phase3 and phase4, but the ValidateMarkSweep live oops
// tracking expects us to do so. See comment under phase4.
GenCollectedHeap* gch = GenCollectedHeap::heap();
GCTraceTime(Info, gc, phases) tm("Phase 2: Compute new object addresses", _gc_timer);
gch->prepare_for_compaction();
