gdb signals

["Vineet Sharma, Noida" <vineets@noida.hcltech.com>]

Hi All,
             I want to know what are the role of signals in gdb simulator
with simulator( i mean in there interfaces gdb and simulator). And how do i
configure the various configrable parts of gdb. Any documnet for that?


I have integerated my new simulator with gdb but before exectuions starts in
my simulator it carshes saying

(gdb) load test.o
Loading section .text, size 0x10 vma 0x0
Start address 0x0
Transfer rate: 128 bits in <1 sec.
(gdb) run test.o

Starting program:  test.o

	Program received signal 0, Signal 0.
	0x00000000 in _main ()



ANd i have debugged , it is not reaching the simulator. It crashes in the
handle_inferior_event() in the following lines   
      
if (signal_print[stop_signal])
    	{
    	  printed = 1;
    	  target_terminal_ours_for_output ();
    	  print_stop_reason (SIGNAL_RECEIVED, stop_signal);
    	}

What is the dependency of these on signals?


Any help or suggestion would be of great help.

Vineet
