/* Main entry point for printing operands.

   XINFO is a `void *' and not a `disassemble_info *' to not put a requirement

   of dis-asm.h on cgen.h.

   This function is basically just a big switch statement.  Earlier versions

   used tables to look up the function to use, but

   - if the table contains both assembler and disassembler functions then

     the disassembler contains much of the assembler and vice-versa,

   - there's a lot of inlining possibilities as things grow,

   - using a switch statement avoids the function call overhead.

   This function could be moved into `print_insn_normal', but keeping it

   separate makes clear the interface between `print_insn_normal' and each of

   the handlers.  */
