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

/* Main entry point for operand extraction.
The result is <= 0 for error, >0 for success.
??? Actual values aren't well defined right now.
This function is basically just a big switch statement. Earlier versions
used tables to look up the function to use, but
- if the table contains both assembler and disassembler functions then
the disassembler contains much of the assembler and vice-versa,
- there's a lot of inlining possibilities as things grow,
- using a switch statement avoids the function call overhead.
This function could be moved into `print_insn_normal', but keeping it
separate makes clear the interface between `print_insn_normal' and each of
the handlers. */
