[Gems-users] Opal wont catch magic breakpoint

[Xuan Qi <xqi@xxxxxxxxxxx>]

Hi everyone,

I am testing the magic breakpoint on my target machine. I use the a simple
program which is provided at $GEMS/opal/benchmark/float.C. The main part
of it is:

......
  /* -- 4 == Do_Breakpoint */
  RUBY_MAGIC_CALL( 4 );

  for (int i = 0; i < numTrials; i++) {

    result_s = ((float32) fabs( pos1_s )) * value_s ;
    result_s = ((float32) fabs( neg1_s )) * value_s ;

    result_d = (fabs( pos1_d )) * value_d ;
    result_d = (fabs( neg1_d )) * value_d ;

  }

  /* -- 4 == Do_Breakpoint */
  RUBY_MAGIC_CALL( 4 );
......

And I use the following script to test the magic breakpoints:

read-configuration sarek-2core.conf
cpu-switch-time 1
instruction-fetch-mode instruction-fetch-trace
istc-disable
dstc-disable
magic-break-enable
load-module ruby
ruby0.setparam g_NUM_PROCESSORS 2
ruby0.setparam g_MEMORY_SIZE_BYTES 536870912
ruby0.setparam g_PROCS_PER_CHIP 2
ruby0.setparam g_NUM_MEMORIES 1
ruby0.setparam NUMBER_OF_VIRTUAL_NETWORKS 6
ruby0.init
@conf.con0.input = "cd ALP/MPGenc/verify\n";
@conf.con0.input = "./float 5\n";
c
echo "first breakpoint"
load-module opal
opal0.init
opal0.sim-start "output_2core.opal"
opal0.sim-step 100000

Simulation will stop at first magic breakpoint and load opal module. But
when opal drives simulation, it won't catch the second magic breakpoint.
Am I missing something? Thank you...

Best regards,
