Sorry, I hit a space and the above mail was mistakenly sent. Again, the code is like this:
@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);
}
}
I
call this function to scan blocks in "available list" at the RELEASE
phase of GC directly after space.release() was called. But I found
there should be some bug in it, but cannot tell where. Could anyone
help me with this?
Thanks in advance.

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);
}
