| 989 | This function is basically just a big switch statement. Earlier versions |
| 990 | used tables to look up the function to use, but |
| 991 | - if the table contains both assembler and disassembler functions then |
| 992 | the disassembler contains much of the assembler and vice-versa, |
| 993 | - there's a lot of inlining possibilities as things grow, |
| 994 | - using a switch statement avoids the function call overhead. |
| 995 | |
| 996 | This function could be moved into `parse_insn_normal', but keeping it |
| 997 | separate makes clear the interface between `parse_insn_normal' and each of |
