DUPM Broadcast logical bitmask immediate to vector (unpredicated) Unconditionally broadcast the logical bitmask immediate into each element of the destination vector. This instruction is unpredicated. The immediate is a 64-bit value consisting of a single run of ones or zeros repeating every 2, 4, 8, 16, 32 or 64 bits. Green False True This instruction is used by the alias MOV SVEMoveMaskPreferred(imm13) See below for details of when the alias is preferred. 0 0 0 0 0 1 0 1 1 1 0 0 0 0 DUPM <Zd>.<T>, #<const> if !IsFeatureImplemented(FEAT_SVE) && !IsFeatureImplemented(FEAT_SME) then UNDEFINED; constant integer esize = 64; constant integer d = UInt(Zd); bits(esize) imm; (imm, -) = DecodeBitMasks(imm13<12>, imm13<5:0>, imm13<11:6>, TRUE, esize); <Zd> Is the name of the destination scalable vector register, encoded in the "Zd" field. <T> Is the size specifier, imm13<12> imm13<5:0> <T> 0 0xxxxx S 0 10xxxx H 0 110xxx B 0 1110xx B 0 11110x B 0 111110 RESERVED 0 111111 RESERVED 1 xxxxxx D <const> Is a 64, 32, 16 or 8-bit bitmask consisting of replicated 2, 4, 8, 16, 32 or 64 bit fields, each field containing a rotated run of non-zero bits, encoded in the "imm13" field.
