[panda-users] Plugin

[Gabriele Viglianisi]

Hi Alessandro,
If you need to access registers, you should use `CPUArchState`, which is
architecture-specific (ie: you should put it inside the right ifdef guard)
You can use it like this:

> #ifdef TARGET_I386
> CPUArchState *env = (CPUArchState*)cpu->env_ptr;
> ... rest of architecture dependent code...
>
> #endif

Regards,
Gabriele
