Hello all ：
I am wondering to know why we must call cpu_pc_from_tb() in the function cpu_exec_nocache() . I found the function cpu_exec_nocache() with comments :“Restore PC. This may happen if async event occurs before the TB starts executing." But I don't know what would happen if async event occurs.
Thanks a los.
