ABSTRACT:
Memory allocation trace data is analyzed by generating a sorted address index containing records of memory allocations, deallocations, and memory address inquiries. The list is scanned once in address order. During scan, a separate sequence index (ordered by sequential indicator) is dynamically maintained, having a record of all allocations pertinent to the current address in the scan. A record is added to the sequence index when its allocation is encountered, and deleted from the sequence index when the scan of the address index goes past the range of the allocated block. Any time a memory address inquiry is encountered during scan of the address index, the sequence indicator of the memory address inquiry is used to find the applicable memory allocation in the sequence index.
