As its name suggests, arm-elf-gcc builds bare-metal ELF that wouldn't
run on linux, doesn't it?
And what about the other question, what does qemu-arm -strace prog print?

Ok, and you build 'prog' as a static linux ELF for ARM?

Ok, what do you execute and where? Is it qemu-arm or qemu-system-arm?
In the latter case do y
I'm in "arm user space" with "sigle step mode". I want write "exit\n" in
linux shell (no QEMU monitor) when emulate code arrives to "return 0"

printf should not write to monitor (if you mean QEMU monitor), it
should go to stdout.
I don't have ARM compiler set up ATM, but x86_64 with the following

Simulated code reaches the point where libc calls 'exit' or 'exit_group' syscall
and the
In arm user mode, where does qemu exit? Where is last qemu's instruction?
I.E.
int main (){return 0;}
in what file does qemu run "return 0"??
