This is a submission of the OptView2 project <https://github.com/OfekShilon/optview2> to be considered upstream.

The suggested changes mostly try to improve SnR (for general devs, as opposed to compiler authors):

1. Exclude system headers by default,
2. Collect only optimization failures by default,
  1. Create option to split processing into subfolders ('--split-top-folders') to enable processing of large projects that typically break otherwise.
3. Trim repeated remark annotations in source - keep only 5 per line.
4. Enable filtering by remark name/text, preferrably via config file (but possible via command line too). Check config.yaml for some examples.
5. A complete rewrite of the index html, making the table sortable and resizable, display a single entry per file/line, use abridged func names, and display remark name instead of pass.

Except the rewrite of index.html and culling of duplicities, all changes can be reverted by command line options.
I uploaded some results of runs over medium/large projects, to get an impression of it:

1. cpython <https://ofekshilon.github.io/optview2-cpython/>
2. opencv <https://ofekshilon.github.io/optview2-opencv/>
3. mujoco <https://ofekshilon.github.io/optview2_mujoco/>
