/* The opcode table.

   The format of the opcode table is:

   NAME OPCODE MASK { OPERANDS }

   NAME		is the name of the instruction.

   OPCODE	is the instruction opcode.

   MASK		is the opcode mask; this is used to tell the disassembler
            	which bits in the actual opcode must match OPCODE.

   OPERANDS	is the list of operands.

   The preceding macros merge the text of the OPCODE and MASK fields.

   The disassembler reads the table in order and prints the first
   instruction which matches, so this table is sorted to put more
   specific instructions before more general instructions.

   Otherwise, it is sorted by major opcode and minor function code.

   There are three classes of not-really-instructions in this table:

   ALIAS	is another name for another instruction.  Some of
		these come from the Architecture Handbook, some
		come from the original gas opcode tables.  In all
		cases, the functionality of the opcode is unchanged.

   PSEUDO	a stylized code form endorsed by Chapter A.4 of the
		Architecture Handbook.

   EXTRA	a stylized code form found in the original gas tables.

   And two annotations:

   EV56 BUT	opcodes that are officially introduced as of the ev56,
   		but with defined results on previous implementations.

   EV56 UNA	opcodes that were introduced as of the ev56 with
   		presumably undefined results on previous implementations
		that were not assigned to a particular extension.
