This article explains what LLVM is, how it differs from GCC, its design for portability, its role in language development, JIT compilation, automatic optimizations, domain‑specific language support, and what it does not handle, providing a comprehensive overview for developers.
This article explains how the Kotlin Compose Compiler uses the intermediate representation (IR) to generate code, covering IR tree structure, traversal with visitors and transformers, and the process of adding composer parameters and restart groups via custom IrGenerationExtension plugins.
This article explains the architecture and evolution of the Kotlin compiler, detailing the roles of the frontend and backend, the transition from K1’s PSI and BindingContext to K2’s FIR and IR, and how Kotlin Compiler Plugins like Compose and No‑arg are implemented.
The article explains how to instrument code for coverage using LLVM’s modular compiler infrastructure—adding compile‑time probes that generate .gcno files, runtime counters that produce .gcda files, and then parsing these with GCOV, while detailing LLVM IR, basic blocks, flow graphs, and extensions for custom plugins.
