Move predicate (unpredicated), setting the condition flags
Read all elements from the source predicate and place in the destination predicate. This instruction is unpredicated. Sets the First (N), None (Z), !Last (C) condition flags based on the predicate result, and the V flag to zero.
This is an alias of ORRS. This means:
| 31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
| 0 | 0 | 1 | 0 | 0 | 1 | 0 | 1 | 1 | 1 | 0 | 0 | Pm | 0 | 1 | Pg | 0 | Pn | 0 | Pd | ||||||||||||
| op | S | o2 | o3 | ||||||||||||||||||||||||||||
is equivalent to
ORRS <Pd>.B, <Pn>/Z, <Pn>.B, <Pn>.B
and is the preferred disassembly when S == '1' && Pn == Pm && Pm == Pg.
| <Pd> |
Is the name of the destination scalable predicate register, encoded in the "Pd" field. |
| <Pn> |
Is the name of the source scalable predicate register, encoded in the "Pn" field. |
The description of ORRS gives the operational pseudocode for this instruction.
