Hallo everyone,
I wrote the following code in SegregatedFreeListSpace(the super class of MarkSweepSpace) to find holes in a block.
@Inline
private void auditBlock (Address block, int sizeClass,
Extent blockSize) {
Extent cellBytes = Extent.fromIntSignExtend(cellSize[sizeClass]);
Address cursor = block.plus(blockHeaderSize[sizeClass]);
Address end = block.plus(blockSize);
while(cursor.LT(end)) {
ObjectReference current = VM.objectModel.getObjectFromStartAddress(cursor);
if (current == null || !this.isCellLive(current)) {
holes++;
}
cursor = cursor.plus(cellBytes);
}
