How do compilers work? How does high-level code get translated into machine code? Today's guest is Matt Godbolt and he knows the answers to these questions. Matt shares his origin story and the creation of compiler explorer in today's interview. This explains why the code unnecessarily shuffles stuff to the stack and back. So, for example, if you want to check if range-based loops in C++ incur some additional runtime cost, you can check the assembly output. This seems like a massive undertaking. It can highlight matching parts in the language and assembly, making it easy to understand how individual expressions are compiled. Enter the Godbolt compiler explorer. It has many different compilers, many self-built. It scales up and down to support demand. Godbolt. Furthermore, it can also work with assembler and LLVM IR. org offers a user-friendly interface that allows you to experiment with code in different programming languages, choose from a variety of compilers, and explore the corresponding assembly code. ) of // an array. a. k.
