All the MIPSen were converted from the old pipeline description (i.e. "define_function_unit") to the new one (i.e. "define_insn_reservation" and friends) in a big patch posted last year: http://gcc.gnu.org/ml/gcc-patches/2004-07/msg01065.html. Maybe you can find in the trhead surrounding that message some ideas on how to convert your r10000 pipeline model. HTH, Gr. Steven
