FMOV (zero, predicated)

Move floating-point +0.0 to vector elements (predicated).

Move floating-point constant +0.0 to to each active element in the destination vector. Inactive elements in the destination vector register remain unmodified.

This is a pseudo-instruction of CPY (immediate, merging). This means:

SVE

FMOV <Zd>.<T>, <Pg>/M, #0.0

is equivalent to

CPY <Zd>.<T>, <Pg>/M, #0

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.

Operation

The description of CPY (immediate, merging) gives the operational pseudocode for this instruction.

Operational information
