/* The opcode table.

   The format of the opcode table is:

   NAME OPCODE MASK CPU CLASS SUBCLASS { OPERANDS } { FLAGS }.

   The table is organised such that, where possible, all instructions with
   the same mnemonic are together in a block.  When the assembler searches
   for a suitable instruction the entries are checked in table order, so
   more specific, or specialised cases should appear earlier in the table.

   As an example, consider two instructions 'add a,b,u6' and 'add
   a,b,limm'.  The first takes a 6-bit immediate that is encoded within the
   32-bit instruction, while the second takes a 32-bit immediate that is
   encoded in a follow-on 32-bit, making the total instruction length
   64-bits.  In this case the u6 variant must appear first in the table, as
   all u6 immediates could also be encoded using the 'limm' extension,
   however, we want to use the shorter instruction wherever possible.

   It is possible though to split instructions with the same mnemonic into
   multiple groups.  However, the instructions are still checked in table
   order, even across groups.  The only time that instructions with the
   same mnemonic should be split into different groups is when different
   variants of the instruction appear in different architectures, in which
   case, grouping all instructions from a particular architecture together
   might be preferable to merging the instruction into the main instruction
   table.

   An example of this split instruction groups can be found with the 'sync'
   instruction.  The core arc architecture provides a 'sync' instruction,
   while the nps instruction set extension provides 'sync.rd' and
   'sync.wr'.  The rd/wr flags are instruction flags, not part of the
   mnemonic, so we end up with two groups for the sync instruction, the
   first within the core arc instruction table, and the second within the
   nps extension instructions.  */
