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

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.
