551 This function is basically just a big switch statement. Earlier versions
552 used tables to look up the function to use, but
553 - if the table contains both assembler and disassembler functions then
554 the disassembler contains much of the assembler and vice-versa,
555 - there's a lot of inlining possibilities as things grow,
556 - using a switch statement avoids the function call overhead.

696 This function is basically just a big switch statement. Earlier versions
697 used tables to look up the function to use, but
698 - if the table contains both assembler and disassembler functions then
699 the disassembler contains much of the assembler and vice-versa,
700 - there's a lot of inlining possibilities as things grow,
701 - using a switch statement avoids the function call overhead.
