Summary

  • This is ASE submission artifact for "Datalog-based Scalable Semantic Diffing of Concurrent Programs".
  • The purpose of this is to show the validity of this work, and show the results shown in the paper.
  • If you have any question, please contact to the authors.
  • To check the results only, you do not have to build and run since all results are already ready (In that case, please just run the script to print tables).

}

To build (tested with LLVM 3.8.0) our program.

  1. Under src, type mkdir build.
  2. cd build
  3. cmake ../ && make

Dependencies

  • Z3 is needed (tested with Z3 4.5.0)
  • Python and other scripts may need to be installed.

Directory

  1. src: LLVM pass of our approach
  2. test: test programs and scripts with benchmark programs we have used for experimental table.
  3. sastest: instrumented test programs of the prior work used for experimental table.

Before running

  • Please extract benchmarks.tar.gz into benchmarks as the size of results is big.

To run test under test

  1. ./run_all-small.sh 1 : run all small sized benchmarks with our approach with rank 1.
  2. ./run_all-small.sh 2 : run all small sized benchmarks with our approach with rank 2.
  3. ./run_all-large.sh 1 : run all large sized benchmarks with our approach with rank 1.
  4. ./run_all-mayHb.sh : run all (small and large) benchmarks to compute mayhb relations.

Print table under test

  1. ./makeTable-small.sh 1 : print a result table for small sized benchmarks with rank 1.
  2. ./makeTable-small.sh 2 : print a result table for small sized benchmarks with rank 2.
  3. ./makeTable-large 1 : print a result table for large sized benchmarks with rank 1.

Etc.

  • We don't have all results of rank 3 since it is meaningless. Some programs do not print result for rank 2 since it does not have more than 2 read from edges.
  • Also, we do not have result table for large size with rank 2, 3 since it is meangless.

To run test under sastest

  1. ./run_all.sh : run all programs used with the prior work. The result will be saved under result directory under each benchmark directory.
