CPY (SIMD&FP scalar) Copy SIMD&FP scalar register to vector elements (predicated) Copy the SIMD & floating-point scalar source register to each active element in the destination vector. Inactive elements in the destination vector register remain unmodified. Green True True True True This instruction is used by the alias MOV (SIMD&FP scalar, predicated) Unconditionally The alias is always the preferred disassembly. 0 0 0 0 0 1 0 1 1 0 0 0 0 0 1 0 0 CPY <Zd>.<T>, <Pg>/M, <V><n> if !IsFeatureImplemented(FEAT_SVE) && !IsFeatureImplemented(FEAT_SME) then UNDEFINED; constant integer esize = 8 << UInt(size); constant integer g = UInt(Pg); constant integer n = UInt(Vn); constant integer d = UInt(Zd); <Zd> Is the name of the destination scalable vector register, encoded in the "Zd" field. <T> Is the size specifier, size <T> 00 B 01 H 10 S 11 D <Pg> Is the name of the governing scalable predicate register P0-P7, encoded in the "Pg" field. <V> Is a width specifier, size <V> 00 B 01 H 10 S 11 D <n> Is the number [0-31] of the source SIMD&FP register, encoded in the "Vn" field.
