Description

Computes the remainder of a 128-bit signed integer division, storing the 128-bit signed remainder in vD. This is a VSX or MMA category instruction. The operation uses the dividend (vA) and divisor (vB) to compute the modulo result, with sign following the dividend.

Operation

vD ← vA mod vB (128-bit signed integer modulo)
