This directory contains debugging and investigation tools for V8.
The contents are regularly mirrored to http://v8.dev/tools.
For local development you have to start a local webserver under http://localhost:8000:
cd tools/; npm install; ws;
The system-analyzer can symbolize profiles for local binaries by running a local symbol server
cd tools/; ws --stack system-analyzer/lws-middleware.js lws-static cors;
Note that the local symbol server will run nm and objdump and has access to your files.
