Soufflé

Soufflé is a translator of declarative Datalog programs into the C++ language. Soufflé is used as a domain-specific language for static program analysis, over large code bases with millions of lines of code. Soufflé aims at producing high-performance C++ code that can be compiled with the native compiler on the target machine.

Features of Soufflé

Efficient translation to parallel C++ of Datalog programs
Extended semantics of Safe Datalog, e.g., permitting unbounded recursions with numbers
Simple component model for Datalog specifications
Recursively defined record types for tuples
Static type system for attributes

How to compile and install

Follow the steps below to compile and install Soufflé on a UNIX system:

G++ 4.8 or newer is recommended to compile Soufflé.
Run sh ./bootstrap to generate configure files
For Linux users, skip this step. MAC OS X does not have C++/OpenMP nor a bison version 3.0.2 installed. We recommend brew to install the required tools to build Soufflé. Run the following commands prior to executing ./configure:

     brew update                
     brew reinstall gcc --without-multilib                
     brew install bison                
     export CXX=/usr/local/bin/g++-5                
     export CXXFLAGS=-fopenmp                
     export SOUFFLECPP=/usr/local/bin/cpp-5
     export BISON=/usr/local/opt/bison/bin/bison

Run ./configure
Run make to build the executable of Soufflé
Test the executable with make check to check whether the compilation of Soufflé succeeded.
Run make install

This command will create the directories and install files in ${DESTDIR}${prefix} for system-wide use in your system.
