1039 This function is basically just a big switch statement. Earlier versions
1040 used tables to look up the function to use, but
1041 - if the table contains both assembler and disassembler functions then
1042 the disassembler contains much of the assembler and vice-versa,
1043 - there's a lot of inlining possibilities as things grow,
1044 - using a switch statement avoids the function call overhead.
1045
1046 This function could be moved into `print_insn_normal', but keeping it
1047 separate makes clear the interface between `print_insn_normal' and each of
1048 the handlers. */
