45 Analyses V8 and perf logs to produce profiles.
47 Perf logs can be collected using a command like:
48 $ perf record -R -e cycles -c 10000 -f -i ./shell bench.js --ll-prof
50 # -e cycles: use cpu-cycles event (run "perf list" for details)
55 This will produce a binary trace file (perf.data) that %prog can analyse.
