129 | This function is basically just a big switch statement. Earlier versions | |
130 | used tables to look up the function to use, but | |
131 | - if the table contains both assembler and disassembler functions then | |
132 | the disassembler contains much of the assembler and vice-versa, | |
133 | - there's a lot of inlining possibilities as things grow, | |
134 | - using a switch statement avoids the function call overhead. | |
135 | ||
136 | This function could be moved into `print_insn_normal', but keeping it | |
137 | separate makes clear the interface between `print_insn_normal' and each of | |
