jsvu v8
ln -l ~/.jsvu/v8 ~/.jsvu/d8
export D8_PATH=~/.jsvu

to install, compile and serve the repository

npm install
npm run install-v8-tools
npm run watch
npm run serve

to get a list of d8 options

node --v8-options

example1.js

Demonstrates inlining.

node ./dist/example1.js 100000
node --v8-options | code -
node --trace-opt --trace-deopt ./dist/example1.js 10000000 | code -
./node_modules/.bin/deoptigate ./dist/example1.js 10000000

example2.js

Demonstrates stable numbers.

node ./dist/example2.js
./node_modules/.bin/deoptigate ./dist/example2.js

example3.js

Demonstrates inline-caching. ip-processor

node ./dist/example3.js
rm *.log; node --trace-ic ./dist/example3.js
./node_modules/.bin/deoptigate ./dist/example3.js
