This git repo contains the source code for crucible and the crucible server

• crucible-server, a standalone process that allows constructing and symbolically executing Crucible programs via a Protocol Buffers.

Crucible has been designed as a set of Haskell packages organized so that Crucible itself has a minimal number of external dependencies, and functionality independent of crucible can be separated into sub-libraries.

Currently, the repo consists of the following Haskell packages:

• crucible provides the core Crucible definitions, the symbolic simulator, the SimpleBackend formula representation, interfaces between SimpleBackend and SMT solvers, and LLVM and MATLAB to Crucible translators.
• crucible-abc provides functionality for generating ABC networks from SimpleBackend expressions.
• crucible-blt provides functionality for generating BLT problems from SimpleBackend expressions.
• crucible-saw provides functionality for generating SAW Core terms from Crucible Control-Flow-Graphs.
• crucible-server provides the crucible-server binary, and also contains a Java API for working with crucible-server.
• galois-matlab provides a few data structures for working with MATLAB values.

For developing crucible, this repo follows a workflow similar to the Gitflow workflow model.

The current development version is in the develop branch, and major feature development should occur in branches of develop that are prefixed with initials identifying the main author of the feature (e.g., jhx-symbolic-fn). Minor fixes can occur directly on develop, but an effort should be made to ensure that develop always builds.

To use stack to build crucible, you can use the shell script scripts/build-sandbox.sh to retrieve the appropriate repos for building.
