# To do profile-guided optimizations of builtins:
# 1. Build with v8_enable_builtins_profiling = true
# 2. Run your chosen workload with the --turbo-profiling-log-builtins flag.
# 2. Run your chosen workload with the --turbo-profiling-output flag.
# For Chrome, the invocation might look like this:
# chrome --no-sandbox --disable-extensions
# --js-flags="--turbo-profiler-output=v8.builtins.pgo"
# --js-flags="--turbo-profiling-output=v8.builtins.pgo"
# "http://localhost/test-suite"
# 3. Run tools/builtins-pgo/get_hints.py to produce the branch hints,
# selecting min_count and threshold_ratio as you wish.
