Support for STL concurrency features in CLAD is a useful feature for applications utilizing cpu threads. Many applications of autodifferentiation benefit from parallel or concurrent processing, and support for some STL concurrency primitives such as threads and basic synchronization primitives may considerably simplify the user's design.

Advanced symbol resolution and re-optimization for Clang-Repl is a Google Summer of Code 2025 project. It aims to improve Clang-Repl and ORC JIT by adding support for automatically loading dynamic libraries when symbols are missing. This removes the need for users to load libraries manually and makes things work more...

Clang-Repl, featuring a REPL(Read-Eval-Print-Loop) environment, allows developers to program in C++ interactively. It is a C++ interpreter built upon the Clang and LLVM incremental compilation pipeline. One of the missing upstream features in Clang-Repl is the ability to propose options for automatically completing user input or code completion. Sometimes, C++...

LLVM JIT APIs include JITLink, a just-in-time linker that links together objects code units directly in memory and executes them. It uses the JITLinkMemoryManager interface to allocate and manage memory for the generated code. When the generated code is run in the same process as the linker, memory is directly...

Incremental C++ enables exploratory programming by considering the translation unit to be an ever-growing entity. This allows implementation of interpreter-like tools such as Cling and Clang-Repl, which consume C++ code piece by piece and use the JIT infrastructure to run each piecewise. One of the challenges of Incremental C++ is...
