REM

Remainder

REM rd, rs1, rs2

Computes the signed remainder of division.

Details

REM computes the signed remainder of rs1 ÷ rs2, writing the result to rd. The sign of the result equals the sign of the dividend (rs1). Remainder by zero yields the dividend; overflow (INT_MIN % −1) yields zero.

Pseudocode Operation

R[rd] = R[rs1] % R[rs2];

Example

REM x5, x6, x7
