About:
C-Reduce is a powerful tool that automatically reduces the size of a C or C++ source file while preserving a specific property, such as a compiler bug. It uses a set of powerful, language-aware passes to systematically remove unnecessary code, making it invaluable for debugging complex issues.
Key Features:
  • Language-aware reduction passes
  • Preserves a property of interest (e.g., a crash)
  • Parallel execution for faster results
  • Effective on large and complex codebases
Use Cases:
  • Isolating the minimal test case for a compiler bug
  • Simplifying code to reproduce a static analysis tool error
  • Reducing a failing test case for a code refactoring tool
Alternatives:
  • delta – Generic line-based reduction tool; less effective for C/C++ syntax.
  • C-Reduce (older versions) – Newer versions include significant performance improvements and more reduction passes.
