Try this: --redirect-code-traces-to=<filename> ;-)

Generally speaking: follow the FLAG_print_opt_code through the source and see what it does.

Depending on where you run V8 (in d8? in Chrome? in node.js?), it might be easiest to just use shell redirection: .../d8 test.js --print-opt-code > output.txt
