Migrating code from one version of LLVM to another can be quite a demanding task, but rest assured as I bring on board over 7 years of experience as a software developer and a comprehensive understanding of not only C++ but also LLVM. Throughout my career, I have worked on similar large projects involving code migration, software architecture, and debugging. In particular, my proficiency in compiler diagnostics and debugging tools will allow me to understand your existing codebase quickly and mitigate any issues that may arise without the need for unit tests.
Moreover, I acknowledge the academic nature of your research project, having traversed a similar path in my career where I've worked with various languages and frameworks like Python, Java (including JVM-related projects), Node.js etc. Having said that, I can confidently affirm that my range of knowledge and adaptability caters effortlessly to new technologies and projects.
