How to trace memory access from V8 during execution

[hrwang]

Hi all,

I was trying to do some research work in V8, but because I'm not familiar with V8's source code,

and I didn't find useful documents to help me with my specific problem, so I'm here to ask for some help.

So if I want to trace every V8's memory access when the engine was executing some

javascript code(not just a number count, I mean some more detailed information about each memory access,

what should I do? If this functionality is not embedded, which part of the source code

should I read and modify (append some code to generate related logs)?

Thank you so much for you patience, if you can help me with some information or direction,

that would be really helpful to me.

Thanks,

hrwang
