Hello,   
      
   I'm currently trying to port LCC to a custom CPU implemented in a   
   FPGA.  A different person is designing the hardware and instruction   
   set.   
      
   I was wondering if there are some general guidelines one should   
   observe when designing an instruction set so that a C compiler can   
   easily be ported to that CPU.   
      
   I'm asking because I'm having a hard time porting LCC with the current   
   instruction set of our custom CPU.   
      
   I've already searched in this group's archive but I couldn't find an   
   answer.   
      
   I can provide more information on our current instruction set if it   
   helps you answer my question, though I don't think it's revelant here.

   [Interesting question.  C should be pretty straightforward on anything   
   with flat byte addressing and enough registers to handle stack frames.   
   What makes this architecture hard? -John]
