OptView2
A developer-focused tool that visualizes Clang/LLVM optimization failures in HTML to help improve C++/Rust code performance.
What is OptView2?
OptView2 is a Python-based tool that processes optimization records generated by Clang and other LLVM-based compilers to create HTML visualizations of optimization failures in source code. It helps developers identify and address performance bottlenecks by highlighting where the compiler could not apply optimizations, making complex compiler data accessible and actionable.
C++ and Rust developers working with Clang, LLVM, or compatible compilers who need to analyze and improve the optimization of their code, particularly in large projects where manual inspection of compiler output is impractical.
Developers choose OptView2 because it focuses exclusively on optimization failures, ignores system headers, and provides an interactive, sortable HTML interface that simplifies navigating and understanding compiler remarks, unlike the original LLVM opt-viewer which targets compiler writers.
