Assembler Symbols

<Wd>

Is the 32-bit name of the general-purpose destination register, encoded in the "Rd" field.
<Wn>

Is the 32-bit name of the first general-purpose source register, encoded in the "Rn" field.
<Wm>

Is the 32-bit name of the second general-purpose source register, encoded in the "Rm" field.
<Xd>

Is the 64-bit name of the general-purpose destination register, encoded in the "Rd" field.
<Xn>

Is the 64-bit name of the first general-purpose source register, encoded in the "Rn" field.
<Xm>

Is the 64-bit name of the second general-purpose source register, encoded in the "Rm" field.

Operation

bits(datasize) result;
bits(datasize) operand1 = X[n, datasize];
bits(datasize) operand2 = X[m, datasize];

(result, -) = AddWithCarry(operand1, operand2, PSTATE.C);

X[d, datasize] = result;
