Preface

A compiler is one of the most prevailing tools used by programmers. The majority of programmers have compilers – or some form of compilation technique – in their development flow. A modern compiler not only transforms high-level programming languages into low-level machine code, but also plays a key role in optimizing the speed, size, or even the memory footprint of the program it compiles. With these characteristics, building a production-ready compiler has always been a challenging task.

LLVM is a framework for compiler optimization and code generation. It provides building blocks that significantly reduce the efforts of developers to create high-quality optimizing compilers and programming language tools. One of its most famous products ...
