Otherwise why use chkp_gimple_call_builtin_p rather than gimple_call_builtin_p? jeffThe reason is that target may provide own version of builtin (and currently does it) for instrumentation. Therefore we should obtain fndecl from target and then compare. That is what chkp_gimple_call_builtin_p does. I just moved gimple code check into chkp_gimple_call_builtin_p to make similar to gimple_call_builtin_p.

OK. Jeff
