Advanced SIMD

AESMC <Vd>.16B, <Vn>.16B

integer d = UInt(Rd); integer n = UInt(Rn); if !HaveAESExt() then UNDEFINED; boolean decrypt = (D == '1');

Assembler Symbols

<Vd>

Is the name of the SIMD&FP destination register, encoded in the "Rd" field.

<Vn>

Is the name of the SIMD&FP source register, encoded in the "Rn" field.

Operation

AArch64.CheckFPAdvSIMDEnabled(); bits(128) operand = V[n]; bits(128) result; if decrypt then result = AESInvMixColumns(operand); else result = AESMixColumns(operand); V[d] = result;
