FMOV (immediate, predicated)

Move floating-point immediate to vector elements (predicated)

This instruction moves a floating-point immediate into each Active element in the destination vector. Inactive elements in the destination vector register remain unmodified.

This is an alias of FCPY. This means:

The encodings in this description are named to match the encodings of FCPY.
The description of FCPY gives the operational pseudocode, any constrained unpredictable behavior, and any operational information for this instruction.

Encoding

FMOV <Zd>.<T>, <Pg>/M, #<const>

is equivalent to

FCPY <Zd>.<T>, <Pg>/M, #<const>

and is always the preferred disassembly.

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	RESERVED
01	H
10	S
11	D

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

<const>

Is a floating-point immediate value expressible as ±n÷16×2^r, where n and r are integers such that 16 ≤ n ≤ 31 and -3 ≤ r ≤ 4, i.e. a normalized binary floating-point encoding with 1 sign bit, 3-bit exponent, and 4-bit fractional part, encoded in the "imm8" field.
