757 This function is basically just a big switch statement. Earlier versions
758 used tables to look up the function to use, but
759 - if the table contains both assembler and disassembler functions then
760 the disassembler contains much of the assembler and vice-versa,
761 - there's a lot of inlining possibilities as things grow,
762 - using a switch statement avoids the function call overhead.
763
764 This function could be moved into `print_insn_normal', but keeping it
765 separate makes clear the interface between `print_insn_normal' and each of
766 the handlers. */
