MOV (vector, predicated)

Move vector elements (predicated).

Move elements from the source vector to the corresponding elements of the destination vector. Inactive elements in the destination vector register remain unmodified.

This is an alias of SEL (vectors). This means:

The encodings in this description are named to match the encodings of SEL (vectors).
The description of SEL (vectors) gives the operational pseudocode for this instruction.

SVE

MOV <Zd>.<T>, <Pg>/M, <Zn>.<T>

is equivalent to

SEL <Zd>.<T>, <Pg>, <Zn>.<T>, <Zd>.<T>

and is the preferred disassembly when Zd == Zm.

Assembler Symbols

<Zd>	Is the name of the destination scalable vector register, encoded in the "Zd" field.

<T>

Is the size specifier, encoded in size:

size	<T>
00	B
01	H
10	S
11	D

<Pg>	Is the name of the governing scalable predicate register, encoded in the "Pg" field.

<Zn>	Is the name of the first source scalable vector register, encoded in the "Zn" field.

Operation

The description of SEL (vectors) gives the operational pseudocode for this instruction.
