NOT (predicate)

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. Does not set the condition flags.

Assembler Symbols

<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 first source scalable predicate register, encoded in the "Pn" field.

Operation

The description of EOR (predicates) gives the operational pseudocode for this instruction.

Operational information

If FEAT_SVE2 is implemented or FEAT_SME is implemented, then if PSTATE.DIT is 1:

The execution time of this instruction is independent of:
- The values of the data supplied in any of its operand registers when its governing predicate register contains the same value for each execution.
- The values of the NZCV flags.
The response of this instruction to asynchronous exceptions does not vary based on:
- The values of the data supplied in any of its operand registers when its governing predicate register contains the same value for each execution.
- The values of the NZCV flags.

NOT (predicate)

NOT <Pd>.B, <Pg>/Z, <Pn>.B is equivalent to EOR <Pd>.B, <Pg>/Z, <Pn>.B, <Pg>.B and is the preferred disassembly when Pm == Pg.
