  12. The manual for gcc version 2.0 says, "No code currently exists to avoid
  13. function unit conflicts, only data conflicts.  Hence multiplicity,
  14. simultaneity, busy-cost, and conflict-list are currently ignored." 
  15. This is true even for the latest version, 2.2.2.  The work I am
  16. currenlty doing needs to have the ability to schedule instructions
  17. with function unit confilicts.  Has anyone modified gcc to include this
  18. feature, or knows of anyone who has done it?  Thanks in advance.
