Lines Matching full:instruction

15  * These values are used with the sync instruction to perform memory barriers.
16  * Types of ordering guarantees available through the SYNC instruction:
22  * specified instructions which are subsequent to the SYNC in the instruction
24  * instructions which are before the SYNC in the instruction stream.
25  * This potentially reduces how many cycles the barrier instruction must stall
34  * - Every synchronizable specified memory instruction (loads or stores or both)
35  *   that occurs in the instruction stream before the SYNC instruction must be
40  * - The barrier does not guarantee the order in which instruction fetches are
46  *   stores preceding the SYNC instruction and both loads and stores that are
47  *   subsequent to the SYNC instruction. Non-zero values of stype may be defined
68  * SYNC instruction completes: Loads, Stores
70  * after the SYNC instruction completes: Loads, Stores
71  * Older instructions which must be globally performed when the SYNC instruction
78  * - Every synchronizable specified memory instruction (loads or stores or both)
79  *   that occurs in the instruction stream before the SYNC instruction must
80  *   reach a stage in the load/store datapath after which no instruction
82  *   instruction which occurs after the SYNC instruction in the instruction
85  * - If any memory instruction before the SYNC instruction in program order,
87  *   instruction after the SYNC instruction in program order also generates a
89  *   older instruction must be globally performed before the time the memory
90  *   request belonging to the younger instruction is globally performed.
92  * - The barrier does not guarantee the order in which instruction fetches are
100  * SYNC instruction completes: Loads, Stores
102  * after the SYNC instruction completes: Loads, Stores
103  * Older instructions which must be globally performed when the SYNC instruction
