Abstract
A framework is provided for automatic inference of memory fences in concurrent programs. A method is provided for generating a set of ordering constraints that prevent executions of a program violating a specification. One or more incoming avoidable transitions are identified for a state and one or more ordering constraints are refined for the state. The set of ordering constraints are generated by taking a conjunction of ordering constraints for all states that violate the specification. One or more fence locations can optionally be selected based on the generated set of ordering constraints.
