Hi!
First of all Happy new year to everybody! :) Wish you all to realize
all your dreams! :)
I edited QEMU user, more exactly qemu-ppc launching the main function
(inside main.c) from another c function I created, passing it the
appropriate parameters.
I also caught the syscall 1 preventing it to abort the process, and
simply returning from cpu_loop function, so that this function is not
more endless, and main returns to my user defined function.
The problem is that launching a second time main with other parameters
fails: leaving the code like it was, the previous translated binary
was kept "in memory" and run again, no matter what binary parameter I
passed to main.
I added then tb_flush(env); after cpu_loop inside main..
But with this edit launching main with other parameters blocks the
execution at tcg_qemu_tb_exec(tc_ptr); ..It sounds like QEMU stores
the state of the translation even after main function is over :(
Is it possible to reset completely the state, allowing consecutive
runs of different binaries?
What are the state variables I should "clean" between different runs?
Thank you very much for your help!
Best regards!

Hi Stefano,
maybe 'qemu -singlestep' helps.
