Re: [Qemu-devel] QEMU as ISS (Instruction Set Simulator)

[Libo Zhou]

Do you know where in the source file I should look into to add my custom 
logging functionality?


Or, would you suggest using gdb to look at my target register and memory 
contents? The answer in this link below looks really promising. I'm gonna give 
it a try first.

However, if I am able to customize log, it will be super convenient.



Cheers,

Libo

I need to do exactly the same thing as you did.

It looks you need a custom logging tailored to your needs, based on
intercepting the instructions you added.
