+/* For backward compatibility only - load a standalone cache macro table */
+
+/* Instruction unpacking:
+
+ Once the instruction has been decoded, the register (and other)
+ fields within the instruction need to be extracted.
+
+ The table that follows determines how each field should be treated.
+ Importantly it considers the case where the extracted field is to
+ be used immediatly or stored in an instruction cache.
+
+ <type>
+
+ Indicates what to do with the cache entry. If a cache is to be
+ used. SCRATCH and CACHE values are defined when a cache entry is
+ being filled while CACHE and COMPUTE values are defined in the
+ semantic code.
+
+ Zero marks the end of the table. More importantly 1. indicates
+ that the entry is valid and can be cached. 2. indicates that that
+ the entry is valid but can not be cached.
+
+ <field_name>
+
+ The field name as given in the instruction spec.
+
+ <derived_name>
+
+ A new name for <field_name> once it has been extracted from the
+ instruction (and possibly stored in the instruction cache).
+
+ <type>
+
+ String specifying the storage type for <new_name> (the extracted
+ field>.
+
+ <expression>
+
+ Specifies how to get <new_name> from <old_name>. If null, old and
+ new name had better be the same. */
