Dat3M 3.1.1 is out!

This release contains our submission for SVCOMP 2023.

It mostly contains changes related to code refactoring and bug fixing for SVCOMP.

Dat3M 3.1.0 is out!

These are the main changes of this version:

• Implements the theory solver for CAAT (Consistency as a Theory) as described in the OOSPLA’22 paper
• Adds support for checking liveness
• Adds support to RC11, IMM and RISCV memory models
• Updates the support to the latests version of LKMM (including data races)
• Implements the compilation schemes from LKMM to hardware models
• Adds macro __VERIFIER_loop_bound to use different unrolling bounds for specific loops
• Adds option encoding.wmm.idl2sat to encode acyclicity constraint using SAT instead of IDL
• Adds option witness.graphviz to generate violation graphs
• Updates JavaSMT version to 3.13.3
• Several bug fixing and performance improvements

Dat3M 3.0.0 is out!

This new major version contains several improvements:

• Support for several SMT solvers based on JavaSMT
• Several performance improvements
• New docker container for easy use
• Extended compilation scheme for more instructions and architectures
• Support for validation of violation witnesses
• Drop support for IDL and KLEENE encodings
• Drop support for Porthos
• Bug fixing

This is the version participating in SVCOMP 2022.

Dat3M 2.0.7 is out!

This is the version participating in SVCOMP 2021. The main new features are listed below.

• Support for bit-vectors
• Improved (machine readable) witness generation
• Checking different properties: currently reachability and no-data-race

Dat3M 2.0.6 is out!

Dartagnan can now verify program written in C.
It uses SMACK (needs to be installed independently) as a backend to convert C programs to Boogie and it then performs the verification on the Boogie representation of the program.
We also improved the IR of programs to support more kind of expressions (including input non-determinism) and implemented loop unrolling of goto instructions.

Dat3M 2.0.3 is out!

The main new feature of this release is the user interface that allows to simulate memory models in just a few clicks instead of running the tools from the console.
