How to Use

The most basic invocation, e.g. incremental_build.sh -- libc, is logically equivalent to

  1. running m --skip-soong-tests libc and then
  2. parsing $OUTDIR/soong_metrics and $OUTDIR/bp2build_metrics.pb files
  3. Adding timing-related metrics from those files into out/timing_logs/metrics.csv
  4. repeat 1-3 for each CUJ

CUJs are defined in cuj_catalog.py Each row in metrics.csv has the timings of various “phases” of a build.

Try incremental_build.sh --help and canoncial_perf.sh --help for help on usage.
