| 29 | Once the instruction has been decoded, the register (and other) | |
| 30 | fields within the instruction need to be extracted. | |
| 31 | ||
| 32 | The table that follows determines how each field should be treated. | |
| 33 | Importantly it considers the case where the extracted field is to | |
| 8eec6289 | 34 | be used immediately or stored in an instruction cache. |

| 38 | Indicates what to do with the cache entry. If a cache is to be | |
| 39 | used. SCRATCH and CACHE values are defined when a cache entry is | |
| 40 | being filled while CACHE and COMPUTE values are defined in the | |
| 41 | semantic code. | |
| 42 | ||
| 43 | Zero marks the end of the table. More importantly 1. indicates | |
| 44 | that the entry is valid and can be cached. 2. indicates that that | |
| 45 | the entry is valid but can not be cached. | |
| 46 | ||
| 47 | <field_name> | |
| 48 | ||
| 49 | The field name as given in the instruction spec. | |
