 160
 161    This function is basically just a big switch statement.  Earlier versions
 162    used tables to look up the function to use, but
 163    - if the table contains both assembler and disassembler functions then
 164      the disassembler contains much of the assembler and vice-versa,
 165    - there's a lot of inlining possibilities as things grow,
 166    - using a switch statement avoids the function call overhead.
 167
 168    This function could be moved into `parse_insn_normal', but keeping it
 169    separate makes clear the interface between `parse_insn_normal' and each of
 170    the handlers.

 465    The assembled instruction, less any fixups, is stored in BUF.

 467    still needs to be converted to target byte order, otherwise BUF is an array
 468    of bytes in target byte order.
 469    The result is a pointer to the insn's entry in the opcode table,
