Description

Divides a 128-bit unsigned integer (vA) by a 128-bit unsigned integer (vB), storing the 128-bit unsigned quotient in vD. This is a VSX or MMA category instruction that performs quadword division. If division by zero is attempted, the result is undefined.

Operation

vD ← vA ÷ vB (128-bit unsigned integer division)
