-/* Instruction decode table:
-
-   <options>:<first>:<last>:<force-first>:<force-last>:<force-expand>:<special>...
-
-
-
-   Ignore the below:
-
-
-   The instruction decode table contains rules that dictate how igen
-   is going to firstly break down the opcode table and secondly
-
-   The table that follows is used by gen to construct a decision tree
-   that can identify each possible instruction.  Gen then outputs this
-   decision tree as (according to config) a table or switch statement
-   as the function idecode.
-
-   In parallel to this, as mentioned above, WITH_EXPANDED_SEMANTICS
-   determines of the semantic functions themselves should be expanded
-   in a similar way.
-
-   <first>
-   <last>
-
-   Range of bits (within the instruction) that should be searched for
-   an instruction field.  Within such ranges, gen looks for opcodes
-   (constants), registers (strings) and reserved bits (slash) and
-   according to the rules that follows includes or excludes them from
-   a possible instruction field.
-
-   <force_first>
-   <force_last>
-
-   If an instruction field was found, enlarge the field size so that
-   it is forced to at least include bits starting from <force_first>
-   (<force_last>).  To stop this occuring, use <force_first> = <last>
-   + 1 and <force_last> = <first> - 1.
-
-   <force_slash>
-
-   Treat `/' fields as a constant instead of variable when looking for
-   an instruction field.
-
-   <force_expansion>
-
-   Treat any contained register (string) fields as constant when
-   determining the instruction field.  For the instruction decode (and
-   controled by IDECODE_EXPAND_SEMANTICS) this forces the expansion of
-   what would otherwize be non constant bits of an instruction.
-
-   <use_switch>
-
-   Should this table be expanded using a switch statement (val 1) and
-   if so, should it be padded with entries so as to force the compiler
-   to generate a jump table (val 2). Or a branch table (val 3).
-
-   <special_mask>
-   <special_value>
-   <special_rule>
-   <special_constant>
-
-   Special rule to fine tune how specific (or groups) of instructions
-   are expanded.  The applicability of the rule is determined by
-
-     <special_mask> != 0 && (instruction> & <special_mask>) == <special_value>
-
-   Where <instruction> is obtained by looking only at constant fields
-   with in an instructions spec.  When determining an expansion, the
-   rule is only considered when a node contains a single instruction.
-   <special_rule> can be any of:
-
-        0: for this instruction, expand by earlier rules
-   	1: expand bits <force_low> .. <force_hi> only
-	2: boolean expansion of only zero/non-zero cases
-	3: boolean expansion of equality of special constant
