   If you add anything, it MUST be in alphabetical order.
   The first field is the name the assembler uses when looking
   up orcodes.  The second field is the name the disassembler will use.
   This allows the assembler to assemble references to r63 (for example)
   or "sp".  The disassembler will always use the preferred form (sp).  */
