Abstract:
Methods and an apparatus for forming a transaction object instruction construct are provided. An example method translates a source instruction construct to form a transactional objective instruction construct, executes the transactional objective instruction construct, intercepts an aborted transaction associated with the transactional objective instruction construct during execution, maintains a graph of nodes and edges associated with the executed transactional objective instruction construct to predict a deadlock situation, and resolves the deadlock situation associated with the transactional objective instruction construct based on the graph.
