126 XINFO is a `void *' and not a `disassemble_info *' to not put a requirement
127 of dis-asm.h on cgen.h.
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.
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
