AESIMC

AES inverse mix columns.

It has encodings from the following instruction sets: A32 ( A1 ) and T32 ( T1 ) .

A1
(FEAT_AES)

Decode for this encoding

if !IsFeatureImplemented(FEAT_AES) then Undefined(); end; if size != '00' then Undefined(); end; if Vd[0] == '1' || Vm[0] == '1' then Undefined(); end; let d : integer = UInt(D::Vd); let m : integer = UInt(M::Vm);

T1
(FEAT_AES)

Decode for this encoding

if InITBlock() then UnpredictableProcedure(); end; if !IsFeatureImplemented(FEAT_AES) then Undefined(); end; if size != '00' then Undefined(); end; if Vd[0] == '1' || Vm[0] == '1' then Undefined(); end; let d : integer = UInt(D::Vd); let m : integer = UInt(M::Vm);
