Identifying code that wastes time performing redundant computation
Abstract:
A method of runtime analysis of a computer program can include, after each access of a first type to a memory address, incrementing a counter associated with the memory address and, after each access of a second type to a memory address, comparing the counter associated with the memory address with a threshold. The method further can include identifying at least one memory address having a counter that exceeds the threshold and determining a portion of code responsible for accessing the memory address associated with the counter that exceeds the threshold.
