gcc with a cpu contain multiple risc units sharing the same register file.

[mike@csdn.sign.idv.tw]

Hello,
   I am porting gcc to a target cpu containing multiple risc units
   sharing the same register file.
   I have read the gcc DFA manual, but I still cannot figure out how the
   describe the pipeline.
   Can I use DFA to describe this target cpu?


   Thanks.
