Description

Performs a bitwise XOR (exclusive OR) of two 128-bit vector registers and stores the result in a third vector register. Each bit position of the result is set if the corresponding bits in the two input vectors differ. No status flags are affected.

Operation

vD ← vA ^ vB

Programming Note

The vxor instruction is used to perform a bitwise XOR operation on two vector registers and store the result in another. Ensure that the Vector Facility (MSR.VEC) is enabled before using this instruction; otherwise, a Vector_Unavailable exception will be raised. This instruction operates on 128-bit vector registers.
