Ross McIlroy 2114287c47 [Turboprop] Improve tierup heuristics for Turboprop 
Slightly lowers the interrupt budget for Turboprop and increases the
interrupt budget scaling factor for TurboFan. This gives the best
balance between benchmark performance and reducing optimization
overhead.

TOOLS

This directory contains debugging and investigation tools for V8.

The contents are regularly mirrored to http://v8.dev/tools.

Local Development

For local development you have to start a local webserver under http://localhost:8000:

  cd tools/;
  npm install;
  ws;

Local Symbol Server

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.
