/** |
* TGSI interpreter/executor. |
* |
* Flow control information: |
* |
* Since we operate on 'quads' (4 pixels or 4 vertices in parallel) |
* flow control statements (IF/ELSE/ENDIF, LOOP/ENDLOOP) require special |
* care since a condition may be true for some quad components but false |
* for other components. |
* |
* We basically execute all statements (even if they're in the part of |
* an IF/ELSE clause that's "not taken") and use a special mask to |
* control writing to destination registers. This is the ExecMask. |
* See store_dest(). |
* |
* The ExecMask is computed from three other masks (CondMask, LoopMask and |
* ContMask) which are controlled by the flow control instructions (namely: |
* (IF/ELSE/ENDIF, LOOP/ENDLOOP and CONT). |
* |
* |
* Authors: |
* Michal Krol |
