Abstract
Transactional programming promises to substantially simplify the development and maintenance of correct, scalable, and efficient concurrent programs. Designs for supporting transactional programming using transactional memory implemented in hardware, software, and a mixture of the two have emerged recently. However, various features and capabilities for debugging programs executed using transactional memory are absent from conventional debuggers. Because transactional memory implementations provide the “illusion” of multiple memory locations changing value atomically, there are challenges involved with integrating debuggers with such programs to provide the user with a coherent view of program execution. For instance, when execution is halted for debugging, a user may request to view a transactional variable or memory location. The transactional variable or memory location may have a pre-transaction value and a tentative value. Allowing a user to only view one of the values reduces the capacity of a user to reason about the behavior of the code.
