Hi Ciro,
Thanks for your reply. I would like to get a sense of how gem5 is run in
general, so single stepping with gdb is a good idea.
I used gdb to single-step x86's 'gem5.debug simple.py', but I wasn't able to
get in the execution loop. I started from main, and after getting in m5Main I
was lost. The "Hello World" was printed all of a sudden.

Subject: Re: [gem5-users] How are registers modelled in gem5?
Libo,
I meant to reply to your previous email, but I waited to see if anyone
had a better reply, and then I forgot to reply.
There is very little documentation available on gem5 internals, but in
general they are not difficult to understand.
I would recommend that you run some very simple content on gem5 e.g.
se.py, e.g. a -nostartfiles linux hello world, and then step debug
gem5 with GDB, and everything should become clear then.
If you reach a more specific question while doing that, do ask,
because then it is more likely that people will be able to answer.
