compilerrt

compilerrt is a hypothetical compiler-runtime framework designed to bridge language front ends and high-performance back ends. It provides a language-agnostic intermediate representation and a modular runtime layer intended to run compiled code across multiple platforms. The project emphasizes portability, safety, and a clean separation between front-end semantics and runtime concerns.

Its architecture comprises a frontend interface that accepts source or IR, a middle-end with optimization passes, and a runtime backend that executes code or emits native modules. It supports both ahead-of-time and just-in-time execution, enabling experimentation with different code-generation strategies while preserving a stable runtime API.

Key features include a language-agnostic intermediate representation, pluggable backends for different targets, and a compact runtime library that provides basic services such as memory management, logging, and error reporting. The design aims to deliver portable binaries with minimal overhead and predictable performance.

Development of compilerrt has been carried out by a broad community of contributors, with discussion on code quality and safety guiding decisions. Since its inception, the project has released a sequence of minor versions that enhance backend extensibility, tooling, and documentation.

In practical settings, compilerrt is used for research, language design experiments, and educational demonstrations. Users value its modularity and clear separation of concerns, while noting that configuring backends and tuning optimizations can present a learning curve.
