Glu is an innovative programming language designed to address specific needs within the modern development ecosystem. Created to replace C as a “glue” between different languages utilizing the LLVM infrastructure, Glu brings several notable advantages.

Limits of C in the Context of LLVM

Traditionally, C has been used to write low-level components that link different systems and programming languages. However, with advancing technologies and the emergence of LLVM infrastructure, C has shown certain limitations:

  • C is prone to security vulnerabilities, particularly those related to memory management.
  • C code can quickly become difficult to maintain, especially when integrating components from multiple languages.
  • C often lacks modern features that facilitate interoperability with high-level languages.

Goals of Glu

Glu was designed to overcome these challenges by offering a more modern and secure solution. Here are some key objectives:

  • By integrating modern security mechanisms, Glu aims to reduce memory management errors.
  • Glu is simpler and more readable than C, thus facilitating code maintenance.
  • Glu seamlessly integrates with LLVM infrastructure, enabling better interaction with languages like Rust, Swift, and Clang.

Reversibility of Glu

A unique feature of Glu is its reversibility. It can generate Glu source code from the optimized LLVM IR representation of a program. This functionality is useful for:

  • Facilitating understanding of compiler behavior and debugging programs.
  • Visualizing and understanding optimizations applied by the compiler.
  • Generating human-readable source code from LLVM IR optimized by other compilers like Clang, Rust, or Swift. In Summary

Glu represents a significant advancement by providing a modern, secure alternative to C for “glue” between different languages using LLVM. Its ability to generate and decompile source code from LLVM IR makes it valuable for developers looking to optimize and debug their code efficiently.
