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
|
|
|
|
|
separate makes clear the interface between `parse_insn_normal' and each of
|
|
|
|
|
the handlers. */
