bool gem5::prefetch::IndirectMemory::PrefetchTableEntry::increasedIndirectCounter |
This variable is set to indicate that there has been at least one match with the current index value.
This information is later used when a new index is updated. If there were no increases in the indirectCounter, the counter is decremented.
