Example 1 with HostedByteBufferPointer

use of com.oracle.svm.core.util.HostedByteBufferPointer in project graal by oracle.

the class AlignedChunkRememberedSet method enableRememberedSet.

@Platforms(Platform.HOSTED_ONLY.class)
public static void enableRememberedSet(HostedByteBufferPointer chunk, int chunkPosition, List<ImageHeapObject> objects) {
    // Completely clean the card table and the first object table.
    CardTable.cleanTable(getCardTableStart(chunk), getCardTableSize());
    FirstObjectTable.initializeTable(getFirstObjectTableStart(chunk), getFirstObjectTableSize());
    Pointer fotStart = getFirstObjectTableStart(chunk);
    UnsignedWord objectsStartOffset = AlignedHeapChunk.getObjectsStartOffset();
    for (ImageHeapObject obj : objects) {
        long offsetWithinChunk = obj.getOffset() - chunkPosition;
        assert offsetWithinChunk > 0 && WordFactory.unsigned(offsetWithinChunk).aboveOrEqual(objectsStartOffset);
        UnsignedWord startOffset = WordFactory.unsigned(offsetWithinChunk).subtract(objectsStartOffset);
        UnsignedWord endOffset = startOffset.add(WordFactory.unsigned(obj.getSize()));
        FirstObjectTable.setTableForObject(fotStart, startOffset, endOffset);
    // The remembered set bit in the header will be set by the code that writes the objects.
    }
}
