LLM4Decompile is an open-source project aimed at creating and releasing the first LLM (Large Language Model) specifically designed for decompilation. It assesses the capabilities of this model by building the first benchmark for decompilation focused on recompilability and executability, known as Decompile-Eval. The project constructs this benchmark by compiling numerous C code samples into assembly code, then fine-tuning the DeepSeek-Coder model using this data.
