Regarding the "-d in_asm", I am fairly sure it will show the asm of
the executed process.

However, since you said you're using the user mode qemu, I think it
will just translated the asm of the user mode of the application. Once
it hits system call request, either via int 80 h or sysenter/syscall,
Qemu will simply run the syscall() function and some other
instructions. Hence, no asm instructions are logged.

Hopefully I explain it correctly.
