552 This function is basically just a big switch statement. Earlier versions

555 the disassembler contains much of the assembler and vice-versa,

732 This function is basically just a big switch statement. Earlier versions
733 used tables to look up the function to use, but
734 - if the table contains both assembler and disassembler functions then
735 the disassembler contains much of the assembler and vice-versa,
736 - there's a lot of inlining possibilities as things grow,
737 - using a switch statement avoids the function call overhead.
739 This function could be moved into `print_insn_normal', but keeping it
740 separate makes clear the interface between `print_insn_normal' and each of
