669 This function is basically just a big switch statement. Earlier versions
670 used tables to look up the function to use, but
671 - if the table contains both assembler and disassembler functions then
672 the disassembler contains much of the assembler and vice-versa,
673 - there's a lot of inlining possibilities as things grow,
674 - using a switch statement avoids the function call overhead.
676 This function could be moved into `print_insn_normal', but keeping it
677 separate makes clear the interface between `print_insn_normal' and each of
678 the handlers. */
