- 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 `parse_insn_normal', but keeping it
