[panda-users] Hook function by name

[Giuseppe Laurenza]

I thought the same things, but looking to the code I see, for example:
getReg (CPUState *cpu, int index)
{
    CPUArchState *env = (CPUArchState*)cpu->env_ptr;
…..

So I think they were different structures. I modify the code to use directly the CPUState object
Thanks

I ask this question in order to avoid to do to many un useful things, sorry if it can appear as a stupid question.
