| 28 | /* Instruction unpacking: | |
| 29 | ||
| 30 | Once the instruction has been decoded, the register (and other) | |
| 31 | fields within the instruction need to be extracted. | |
| 32 | ||
| 33 | The table that follows determines how each field should be treated. | |
| 34 | Importantly it considers the case where the extracted field is to | |
| 35 | be used immediatly or stored in an instruction cache. | |
| 36 | ||
| 37 | <type> | |
| 38 | ||
| 39 | Indicates what to do with the cache entry. If a cache is to be | |
| 40 | used. SCRATCH and CACHE values are defined when a cache entry is | |
| 41 | being filled while CACHE and COMPUTE values are defined in the | |
| 42 | semantic code. | |
| 43 | ||
| 44 | Zero marks the end of the table. More importantly 1. indicates | |
| 45 | that the entry is valid and can be cached. 2. indicates that that | |
| 46 | the entry is valid but can not be cached. | |
| 47 | ||
| 48 | <field_name> | |
| 49 | ||
| 50 | The field name as given in the instruction spec. | |
| 51 | ||
| 52 | <derived_name> | |
| 53 | ||
| 54 | A new name for <field_name> once it has been extracted from the | |
| 55 | instruction (and possibly stored in the instruction cache). | |
| 56 | ||
| 57 | <type> | |
| 58 | ||
| 59 | String specifying the storage type for <new_name> (the extracted | |
| 60 | field>. | |
| 61 | ||
| 62 | <expression> | |
| 63 | ||
| 64 | Specifies how to get <new_name> from <old_name>. If null, old and | |
| 65 | new name had better be the same. */ | |
