Assembler Symbols

<Xt>

Is the 64-bit name of the general-purpose destination register, encoded in the "Rt" field.

<op1>

Is a 3-bit unsigned immediate, in the range 0 to 7, encoded in the "op1" field.

<Cn>

Is a name 'Cn', with 'n' in the range 0 to 15, encoded in the "CRn" field.

<Cm>

Is a name 'Cm', with 'm' in the range 0 to 15, encoded in the "CRm" field.

<op2>

Is a 3-bit unsigned immediate, in the range 0 to 7, encoded in the "op2" field.

Operation
