Bitwise invert predicate, setting the condition flags
Bitwise invert each active element of the source predicate, and place the results in the corresponding elements of the destination predicate. Inactive elements in the destination predicate register are set to zero. 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 EORS. 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 | 0 | 1 | 0 | 0 | Pm | 0 | 1 | Pg | 1 | Pn | 0 | Pd | ||||||||||||
| op | S | o2 | o3 | ||||||||||||||||||||||||||||
is equivalent to
EORS <Pd>.B, <Pg>/Z, <Pn>.B, <Pg>.B
and is the preferred disassembly when Pm == Pg.
| <Pd> |
Is the name of the destination scalable predicate register, encoded in the "Pd" field. |
| <Pg> |
Is the name of the governing scalable predicate register, encoded in the "Pg" field. |
| <Pn> |
Is the name of the source scalable predicate register, encoded in the "Pn" field. |
The description of EORS gives the operational pseudocode for this instruction.
