Hi all,
I am writing an DFA Scheduler for a new target port on GCC by define_automata. But it doesn't run.
I checked in haifa-sched.c and saw that 
targetm.sched.use_dfa_pipeline_interface
      && (*targetm.sched.use_dfa_pipeline_interface) ()
return false; so the function dfa_start () didn't run.
I also redefine for hook TARGET_SCHED_USE_DFA_PIPELINE_INTERFACE
Can you help me to explain this?
Thank in advance.
