I should add that while speedups are nice, my main interest is quality
of final output.

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 '#'
