I wonder which tool you used to draw these diagrams. These diagrams look very professional, much better than mine 😢

LOL, really? The previous one is quoted from the previous Mosn source code analysis, which should be drawn with PPT. The following picture is drawn casually with the online software Processon. The function of this software is similar to that of visio, but it can be drawn anywhere and opened. This is very convenient and you can try it.

ok. I used processon before, but the diagrams I drawed are too ugly...... 😢

I was wondering about this problem just now, and later found out that I have two similar branch names, so the branch of this pr is wasm_code_analysis, not webassembly_code_analysis. So now, do I cherry-pick the changes or do you pr to the wasm_code_analysis branch?

[seeflood]

@rayowang OK you can cherry pick those changes

@rayowang OK you can cherry pick those changes
