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.
