 543
 544    This function is basically just a big switch statement.  Earlier versions
 545    used tables to look up the function to use, but
 546    - if the table contains both assembler and disassembler functions then
 547      the disassembler contains much of the assembler and vice-versa,
 548    - there's a lot of inlining possibilities as things grow,
 549    - using a switch statement avoids the function call overhead.
 550
 551    This function could be moved into `parse_insn_normal', but keeping it
 552    separate makes clear the interface between `parse_insn_normal' and each of
 553    the handlers.  It's also needed by GAS to insert operands that couldn't be
 554    resolved during parsing.  */

 866
 867    This function is basically just a big switch statement.  Earlier versions
 868    used tables to look up the function to use, but
 869    - if the table contains both assembler and disassembler functions then
 870      the disassembler contains much of the assembler and vice-versa,
 871    - there's a lot of inlining possibilities as things grow,
 872    - using a switch statement avoids the function call overhead.
 873
 874    This function could be moved into `print_insn_normal', but keeping it
 875    separate makes clear the interface between `print_insn_normal' and each of
 876    the handlers.  */
