Bitwise exclusive OR with immediate (unpredicated).
Bitwise exclusive OR an immediate with each 64-bit element of the source vector, and destructively place the results in the corresponding elements of the source vector. 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. This instruction is unpredicated.
This instruction is used by the pseudo-instruction EON.
if !HaveSVE() then UNDEFINED; integer dn = UInt(Zdn); bits(64) imm; (imm, -) = DecodeBitMasks(imm13<12>, imm13<5:0>, imm13<11:6>, TRUE);
Is the name of the source and destination scalable vector register, encoded in the "Zdn" field.
Is the size specifier,
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.
This instruction might be immediately preceded in program order by a MOVPRFX instruction that conforms to all of the following requirements, otherwise the behavior of either or both instructions is unpredictable:
- The MOVPRFX instruction must specify the same destination register as this instruction.
- The destination register must not refer to architectural register state referenced by any other source operand register of this instruction.
- An unpredicated MOVPRFX instruction.
