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

772 This function is basically just a big switch statement. Earlier versions
773 used tables to look up the function to use, but
774 - if the table contains both assembler and disassembler functions then
775 the disassembler contains much of the assembler and vice-versa,
776 - there's a lot of inlining possibilities as things grow,
777 - using a switch statement avoids the function call overhead.
779 This function could be moved into `print_insn_normal', but keeping it
