Re: [Gems-users] Magic Instructions

["Marco Tirado" <marco.tirado@xxxxxxxxx>]

We had the same problem when doing simulations with solaris 9. The simulation did not stop even when using the MAGIC BREAKPOINT macro directly. We solved it by defining a hap callback where we simply stop SIMICS, we used the MAGIC BREAKPOINT macro directly and the hap callback definition in our script looks like this.

 

@def hap_callback(user_arg, cpu, arg):

        SIM_break_simulation("MAGIC Breakpoint")

@SIM_hap_add_callback("Core_Magic_Instruction", hap_callback, None)

Hope this helps.

Try the following code. It uses 0x40000 explicitly (4<<16):

#define MAGIC_BREAK do {                                   \

} while (0);
