284 
 
285 
   This function is basically just a big switch statement.  Earlier versions
286 
   used tables to look up the function to use, but
287 
   - if the table contains both assembler and disassembler functions then
288 
     the disassembler contains much of the assembler and vice-versa,
289 
   - there's a lot of inlining possibilities as things grow,
290 
   - using a switch statement avoids the function call overhead.
291 
 
292 
   This function could be moved into `print_insn_normal', but keeping it
293 
   separate makes clear the interface between `print_insn_normal' and each of
294 
   the handlers.  */
