The build benchmark

This benchmark executes a complete build of the stage3 stdlib from stage2 and collects global and per-module metrics. This is different from most other benchmarks, which benchmark the stage the bench suite is being executed in.

The following metrics are collected by a wrapper around the entire build process:

• build//cycles
• build//instructions
• build//maxrss
• build//task-clock
• build//wall-clock

The following metrics are collected from leanc --profile and leanc --stat and summed across all modules:

• build/profile/<name>//wall-clock
• build/stat/<name>//amount
• build/stat/<name>//bytes

The following metrics are collected from lakeprof report:

• build/lakeprof/longest build path//wall-clock
• build/lakeprof/longest rebuild path//wall-clock

The following metrics are collected individually for each module:

• build/module/<name>//lines
• build/module/<name>//cycles
• build/module/<name>//instructions
• build/module/<name>//bytes .ilean
• build/module/<name>//bytes .olean
• build/module/<name>//bytes .olean.server
• build/module/<name>//bytes .olean.private

If the file build_upload_lakeprof_report is present in the repo root, the lakeprof report will be uploaded once the benchmark run concludes.
