V8 deoptimizations

[Ω Alisson]

Does anyone knows if the V8 engine on latest io.js still deoptimizes generators, const and let?

[Fedor Indutny]

Doesn't seem to be!

$ ./iojs --trace-deopt -e 'function* a() { yield 1}; var x = a(); console.log(x.next())'

[deoptimize global object @ 0x243990e18d41]

{ value: 1, done: false }

NOTE: this global object thing is unrelated, and happens anyway.
