This would be interesting to try, but it's way too much work for me. As the supervisor here, I only tackle easy programming projects.

It's possible that Yang could make time for this.

  Hi all,

  As you may know, there is a clang-based tool "Include What You Use" [1]. I 
think similar approach could be useful in C-Reduce to remove whole header files instead 
of separate lines. Though I'm not sure it's feasible without non-preprocessed source file 
and compilation command line available.

  I can imagine the next algorithm of reduction:

  1. Reduce only the last section of translation unit corresponding to original 
source file without #includes using all available passes.
  2. Try to remove sections corresponding to "unused" headers
  3. Move to section N-1 and proceed.

Algorithm without file-level logic:

0. Remove empty lines
1. Reduce part of translation unit after last line starting with '#' using all 
available passes.
2. Aggressively eliminate / replace with forward declaration any unused 
function / classes.

And, most important, unused templates.

3. Move to the next non-empty section between lines starting with '#'
