How can I see the machine code generated by v8?

Question

Does anybody know how I can see the actual machine code that v8 generates from Javascript? I\'ve gotten as far as Script::Compile() in src/api.cc b

Answer 1

Try with NodeJS or Chrome:

1. -print-opt-code: Code generated by optimizing compiler.
2. -print-bytecode: Byte code generated by interpreter.
3. -trace-opt and -trace-depot : which functions are (de)optimized.

Check this article by @Franziska Hinkelmann :

Additionally you can also try

D8: It will help you compile V8 and view the assembly code generated from JavaScript.
