 549    This function is basically just a big switch statement.  Earlier versions
 550    used tables to look up the function to use, but
 551    - if the table contains both assembler and disassembler functions then
 552      the disassembler contains much of the assembler and vice-versa,
 553    - there's a lot of inlining possibilities as things grow,
 554    - using a switch statement avoids the function call overhead.
 555
 556    This function could be moved into `parse_insn_normal', but keeping it
 557    separate makes clear the interface between `parse_insn_normal' and each of
 558    the handlers.  It's also needed by GAS to insert operands that couldn't be
 559    resolved during parsing.  */
