Hello all =A3=BA
I am wondering to know  why we must call  cpu_pc_from_tb()&= nbsp;=20 in the function cpu_exec_nocache() . I found the function cpu_exec_nocache= ()=20 with comments :=A1=B0Restore PC.  This may happen if async event occu= rs=20 before  the TB starts executing."  But I don't know what would h= appen=20 if async event occurs.
Thanks a los.
