示例1: allocate_stacks
void GenMarkSweep::allocate_stacks() {
GenCollectedHeap* gch = GenCollectedHeap::heap();
// Scratch request on behalf of old generation; will do no allocation.
ScratchBlock* scratch = gch->gather_scratch(gch->old_gen(), 0);
// $$$ To cut a corner, we'll only use the first scratch block, and then
// revert to malloc.
if (scratch != NULL) {
_preserved_count_max =
scratch->num_words * HeapWordSize / sizeof(PreservedMark);
} else {
_preserved_count_max = 0;
}
_preserved_marks = (PreservedMark*)scratch;
_preserved_count = 0;
}
