/* This structure holds information for a particular instruction.

   The args field is a string describing the operands.  The following
   letters can appear in the args:
     b - a 5.3-bit right source register index OR 8-bit unsigned immediate
     B - same as 'b', but for LOOP instruction where IMM is decremented
     c - a 5 bit unsigned immediate for constant table offset
     d - a 5.3-bit destination register index
     D - a 5.2-bit destination register index
     E - for internal GAS self-tests only
     i - a 32-bit immediate or label
     j - a 5.3-bit right source register index OR 18-bit PC address
     l - burst length (unsigned 7-bit immediate or r0.b[0-3]) for xLBCO
     n - burst length (unsigned 7-bit immediate or r0.b[0-3]) for XFR
     o - a 10-bit signed PC-relative offset
     O - an 8-bit unsigned PC-relative offset for LOOP termination point
     R - a 5-bit destination register index
     s - a 5.3-bit left source register index
     S - a 5-bit left source register index
     w - a single bit for "WakeOnStatus"
     W - a 16-bit unsigned immediate with IO=0 field (LDI)
     x - an 8-bit XFR wide-bus address immediate
   Literal ',' character may also appear in the args as delimiter.

   Most of the macro names are from [1].

   The pinfo field is INSN_MACRO for a macro.  Otherwise, it is a collection
   of bits describing the instruction, notably any relevant hazard
   information.

   When assembling, the match field contains the opcode template, which
   is modified by the arguments to produce the actual opcode
   that is emitted.  If pinfo is INSN_MACRO, then this is 0.

   If pinfo is INSN_MACRO, the mask field stores the macro identifier.
   Otherwise this is a bit mask for the relevant portions of the opcode
   when disassembling.  If the actual opcode anded with the match field
   equals the opcode field, then we have found the correct instruction.
