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 general-purpose source register, encoded in the "Rn" field.

<simm>

Is a signed immediate, in the range -128 to 127, encoded in the "imm8" 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 general-purpose source register, encoded in the "Rn" field.

Operation

bits(datasize) operand1 = X[n, datasize]; integer result = Min(SInt(operand1), imm); X[d, datasize] = result<datasize-1:0>;
