128-bit SVE

Set all 16-bit lanes of (2) to the immediate value from (1). The value from (1) must be representable as an 8-bit floating-point immediate.

256-bit SVE

Set all 16-bit lanes of (2) to the immediate value from (1). The value from (1) must be representable as an 8-bit floating-point immediate.

512-bit SVE

Set all 16-bit lanes of (2) to the immediate value from (1). The value from (1) must be representable as an 8-bit floating-point immediate.

Larger sizes

1024-bit SVE

Set all 16-bit lanes of (2) to the immediate value from (1). The value from (1) must be representable as an 8-bit floating-point immediate.

2048-bit SVE

Set all 16-bit lanes of (2) to the immediate value from (1). The value from (1) must be representable as an 8-bit floating-point immediate.
