Description

Performs a bitwise logical OR of the contents of XA and XB, storing the result in XT. This is a VSX instruction that does not affect condition or status flags.

Operation

XT ← XA | XB

Programming Note

The xxlor instruction is used to perform a bitwise OR operation on two VSX registers. Ensure that the VSX facility is enabled by checking and setting the MSR.VSX bit; otherwise, a VSX_Unavailable exception will be raised. This instruction operates on 128-bit vectors and requires proper alignment of the input and output registers.
