VXOR

Operation

Applies bitwise XOR to corresponding active vector elements.

VECTOR

The register form computes the selected-width bitwise exclusive OR of each active source lane and corresponding old destination lane, then writes the result to the destination. When memory is the source, each active memory element is XORed with the corresponding old destination lane. In both forms, an inactive destination lane retains its previous value.

The memory-destination form reads each active destination element, computes its selected-width bitwise exclusive OR with the corresponding source-register lane, and writes the result back to the same element. An inactive memory element remains unchanged.
