Merging Size Diffs

When looking at a diff across milestones, it can be useful to filter out the size impacts due to toolchain changes (e.g. compiler or R8 rolls).

You will need:

  1. The .size files of the milestones you'd like to diff.
  2. The .sizediff files of the commits to filter out.

Then run:

tools/binary_size/create_patched_supersize_diff.py before_size.size load_size.size *.sizediff --output m97_m98_normalized.sizediff

And then run the gsutil.py command that it prints out.
