# --- Baseline workflow -------------------------------------------------------
#
# `make baseline` snapshots the current binary as bin/rugo-baseline. Re-running
# it overwrites the snapshot, so checkout an older revision first when you
# want to capture a "before" build.
#
# `make rats-compare` runs the entire RATS suite twice (baseline first, then
# current bin/rugo) and reports total wall-clock time for each so you can see
# the impact of compiler changes on real test runs.
#
# `make bench-compare` runs the type-inference benchmarks with inference on
# (current default) and off (--no-infer), so the inference engine's payoff is
# visible in numbers.
