[Qemu-devel] Doubts about qemu tcg/tci

Hi,

Hopefully I'm sending this e-mail to the right list. If not, please ignore
it!

I'm trying to read the asm code generated with the -D qemu option, but I am
having some difficulties.

First, I've seen that the generated asm is allocated in different address
ranges. The beginning of the dump says:

end_code    0x080486dc
start_code  0x08048000

but the first instruction's address is: 0x6022caf0

Am I misunderstanding something? How exactly this reallocation happens (or
where in the source code am I able to track and understand the process)?

Second, what exactly means the identifying letters of arguments counted in
front of each instruction (i, o, c) ? Is it too hard to create a patch on
the disassembly function to also output its values?

Third, Is there a trivial way for me to track an original function inside
the generated asm dump? I mean, if I create a C function called foo(), that
is called somewhere inside the main function, what should I do in order to
find the translated instructions inside the outputted dump?

Finally, I've been trying to find material about how this translation works
properly, but I've been unable to find much. Is there something I should be
reading before asking around here? If yes, please, point me to it!

Thank you for your time. Any help with any question will be very useful to
me.
