project-everest/vale

This system is a formal verification toolchain for the Vale programming language, designed to verify and execute code against hardware architectures. It provides a build system and infrastructure for integrating with F* and Dafny, enabling the specification and verification of x64, ARM, and PowerPC architectures. The system supports direct execution of verified code, manages dependencies like Z3 and KreMLin, and includes comprehensive test suites to ensure correctness across different platforms.

This period focused on establishing the project's infrastructure, introducing a new SCons-based build system and initializing the repository structure. Significant work was also done on the Vale tooling, including refactoring the AST and typechecker, adding x86 machine model support, and creating comprehensive test suites for the Vale/F* integration.

This period focused on establishing formal verification support for x86-64, PowerPC, and ARM architectures by introducing new F* and Dafny specification files and test cases. The work included building the necessary infrastructure, such as the ImportFStarTypes tool and Docker build scripts, to enable the import and use of types from external languages and automate the CI process.

This period focused on expanding the formal verification capabilities of the Vale language by adding architecture-specific definitions for x64 and PowerPC64LE in F*. Additionally, the project improved developer workflows through an interactive verification script and migrated its documentation to Read the Docs.
