|

This function is basically just a big switch statement. Earlier versions
|

used tables to look up the function to use, but
|
||
- if the table contains both assembler and disassembler functions then
|
||
the disassembler contains much of the assembler and vice-versa,
|
||
- there's a lot of inlining possibilities as things grow,
|
||
- using a switch statement avoids the function call overhead.
|

|

This function could be moved into `print_insn_normal', but keeping it

separate makes clear the interface between `print_insn_normal' and each of

the handlers. */
