 I have a similar problem with the following insn using GCC 1.40 with
 my own 16 bit machine description.
   (insn 17 15 18 (set(mem:HI(predec:HI (reg:HI 5)))
      (reg/v:HI 23)) -1 (insn_list(10 nil)))

 I understand about the (set(mem:HI ...), but how do I create a description
 for reg/v:HI 23,  better yet, where do I look in the documentation for
 reg/v or any other reg/ information.

 My machine only has 4 general purpose registers, plus stack pointer etc
 so the rev/v:HI 23 must be a pseudo register I am trying to load from.

Thank you in advance for your help.

P.S. I have not net snagged GCC 2.0, thought I would wait for 2.01.
