[heap] Use HashMap as scratchpad backing store We use a scratchpad to remember visited allocation sites for post processing (making tenure decisions). The previous implementation used a rooted FixedArray with constant length (256) to remember all sites. Updating the scratchpad is a bottleneck in any parallel/concurrent implementation of newspace evacuation. The new implementation uses a HashMap with allocation sites as keys and temporary counts as values. During evacuation we collect a local hashmap of visited allocation sites. Upon merging the local hashmap back into a global one we update potential forward pointers of compacted allocation sites. The scavenger can directly enter its entries into the global hashmap. Note that the actual memento found count is still kept on the AllocationSite as it needs to survive scavenges and full GCs.

[heap] Use HashMap as scratchpad backing store We use a scratchpad to remember visited allocation sites for post processing (making tenure decisions). The previous implementation used a rooted FixedArray with constant length (256) to remember all sites. Updating the scratchpad is a bottleneck in any parallel/concurrent implementation of newspace evacuation. The new implementation uses a HashMap with allocation sites as keys and temporary counts as values. During evacuation we collect a local hashmap of visited allocation sites. Upon merging the local hashmap back into a global one we update potential forward pointers of compacted allocation sites. The scavenger can directly enter its entries into the global hashmap. Note that the actual memento found count is still kept on the AllocationSite as it needs to survive scavenges and full GCs.
