VDUP

Operation

Broadcasts an integer scalar register or immediate value to every vector lane.

Assembler Syntax

VDUP.{B|W|L|Q}(z) Rn(r), Vn(v)

Required CPUID flags

VECTOR

VDUP fills every selected-width destination lane with the same source value. The integer-register forms use the low B, W, L, or Q field of Rn; the immediate forms broadcast their complete encoded B, W, L, or Q value. The operation replaces the complete destination vector image.

VDUP.W scalar broadcast
