+The dataset consists of source code and LLVM IR pairs generated from accepted and de-duped programming contest solutions. The dataset is divided into language configs and mode splits. The language can be one of `C`, `C++`, `D`, `Fortran`, `Go`, `Haskell`, `Nim`, `Objective-C`, `Python`, `Rust` and `Swift`, indicating the source files' languages. The mode split indicates the compilation mode, which can be wither `Size_Optimized` or `Perf_Optimized`.
