About Compiler Explorer

Compiler Explorer (godbolt.org) is the interactive site where you edit code in C, C++, C#, F#, Rust, Go, D, Haskell, Swift, Python, Java and 30+ other languages and see how it looks once compiled, in real time. Its MCP server brings that to Claude. Ask Claude to compile a snippet with a given compiler and flags, compare the assembly produced by two compiler versions, or explain what an optimisation changed, then share the result as a godbolt.org link. Example requests: "Compile this loop with GCC and Clang at -O2 and compare the assembly", "Does this Rust function get vectorised?", "Explain why adding const changes the generated code". Useful for performance work, teaching and debugging compiler behaviour.
