Compiler Explorer MCP

# Compiler Explorer MCP A Model Context Protocol (MCP) server that connects LLMs to the Compiler Explorer API, enabling them to compile code, explore compiler features, and analyze optimizations across different compilers and languages. ## Example Questions Here are some interesting questions you can ask your LLM using this MCP: ### Compiler Feature Exploration - "What is the earliest version of GCC that supports the `#embed` directive?" - "Show me how different versions of Clang handle C++20 modules" - "What optimization flags are available in Clang 12 that weren't in Clang 11?" - "Can you demonstrate how MSVC and GCC handle C++20 coroutines differently?" ### Optimization Analysis - "What's the assembly difference between `-O2` and `-O3` for a simple recursive Fibonacci function in GCC 13?" - "How does Clang's vectorization compare to GCC's for a basic matrix multiplication?" - "Show me how different optimization levels affect tail-call optimization in this recursive function" - "What's the impact of `-ffast-math` on this floating-point heavy computation?" ### Language Feature Support - "Which C++20 features are supported in the latest versions of GCC, Clang, and MSVC?" - "Show me how different compilers implement std::optional's memory layout" - "Compare how GCC and Clang handle C++20's constexpr virtual functions" - "Demonstrate the differences in how Intel and GCC compilers auto-vectorize SIMD operations" ### Assembly Deep Dives - "What's the most efficient way to implement a population count in x86 assembly across different CPU architectures?" - "Show me how different compilers optimize a simple string reverse function at -O3" - "Compare the assembly output of a virtual function call vs a normal function call" - "How do different compilers implement std::variant's type switching in assembly?" ### Cross-Language Comparison - "Compare the generated assembly for the same algorithm in C++, Rust, and Go" - "How do exception handling mechanisms differ between C++ and Rust in terms of generated code?" - "Show me the overhead of Rust's bounds checking compared to unchecked C++ array access" - "Compare how C++ and D implement RAII in terms of generated assembly" ### Performance Investigation - "What's the assembly-level difference between using std::sort and a hand-written quicksort?" - "Show me how different string concatenation methods compare in terms of generated instructions" - "Compare the efficiency of std::map vs std::unordered_map operations in assembly" - "How do different smart pointer implementations affect inlining and code size?"
