Abstract
Exemplary methods, apparatuses, and systems generate a plurality of possible branch traces for a computer program. Each possible branch trace represents different sequences of branch instructions that may be executed while the computer program is running. Each branch instruction has a corresponding identifier. A branch trace value is generated for at least one of the plurality of possible branch traces. Generating the branch trace value includes performing a mathematical or logical operation between a first identifier and each subsequent identifier of the possible branch trace to obtain the branch trace value. An output including a branch trace is generated based upon a match between a run-time branch trace value and the at least one generated branch trace value.
