示例1: m
void G1MarkSweep::mark_sweep_phase4() {
// All pointers are now adjusted, move objects accordingly
// It is imperative that we traverse perm_gen first in phase4. All
// classes must be allocated earlier than their instances, and traversing
// perm_gen first makes sure that all klassOops have moved to their new
// location before any instance does a dispatch through it's klass!
// The ValidateMarkSweep live oops tracking expects us to traverse spaces
// in the same order in phase2, phase3 and phase4. We don't quite do that
// here (perm_gen first rather than last), so we tell the validate code
// to use a higher index (saved from phase2) when verifying perm_gen.
G1CollectedHeap* g1h = G1CollectedHeap::heap();
Generation* pg = g1h->perm_gen();
EventMark m("4 compact heap");
TraceTime tm("phase 4", PrintGC && Verbose, true, gclog_or_tty);
GenMarkSweep::trace("4");
pg->compact();
G1SpaceCompactClosure blk;
g1h->heap_region_iterate(&blk);
