Getting rid of store-buffers in TSO analysis

Atig, Mohamed Faouzi, Bouajjani, Ahmed and Parlato, Gennaro (2011) Getting rid of store-buffers in TSO analysis At 23rd International Conference on Computer Aided Verification (CAV 2011), United States. 14 - 20 Jul 2011. 16 pp, pp. 99-115.

Record type: Conference or Workshop Item (Paper)


We propose an approach for reducing the TSO reachability analysis of concurrent programs to their SC reachability analysis, under some conditions on the explored behaviors. First, we propose a linear code-to-code translation that takes as input a concurrent program P and produces a concurrent program P? such that, running P? under SC yields the same set of reachable (shared) states as running P under TSO with at most k context-switches for each thread, for a fixed k. Basically, we show that it is possible to use only O(k) additional copies of the shared variables of P as local variables to simulate the store buffers, even if they are unbounded. Furthermore, we show that our translation can be extended so that an unbounded number of context-switches is possible, under the condition that each write operation sent to the store buffer stays there for at most k context-switches of the thread. Experimental results show that bugs due to TSO can be detected with small bounds, using off-the-shelf SC analysis tools.
