547 This function is basically just a big switch statement. Earlier versions
548 used tables to look up the function to use, but
549 - if the table contains both assembler and disassembler functions then
550 the disassembler contains much of the assembler and vice-versa,
551 - there's a lot of inlining possibilities as things grow,
552 - using a switch statement avoids the function call overhead.
554 This function could be moved into `parse_insn_normal', but keeping it
555 separate makes clear the interface between `parse_insn_normal' and each of
556 the handlers. It's also needed by GAS to insert operands that couldn't be

747 This function is basically just a big switch statement. Earlier versions
748 used tables to look up the function to use, but
749 - if the table contains both assembler and disassembler functions then
750 the disassembler contains much of the assembler and vice-versa,
751 - there's a lot of inlining possibilities as things grow,
752 - using a switch statement avoids the function call overhead.
754 This function could be moved into `print_insn_normal', but keeping it
755 separate makes clear the interface between `print_insn_normal' and each of
