// *********************************** NOTE ***********************************
// ** For POWER8 Little Endian, the VSX swap optimization relies on knowing **
// ** which VMX and VSX instructions are lane-sensitive and which are not. **
// ** A lane-sensitive instruction relies, implicitly or explicitly, on **
// ** whether lanes are numbered from left to right. An instruction like **
// ** VADDFP is not lane-sensitive, because each lane of the result vector **
// ** relies only on the corresponding lane of the source vectors. However, **
// ** an instruction like VMULESB is lane-sensitive, because "even" and **
// ** "odd" lanes are different for big-endian and little-endian numbering. **
// ** **
// ** When adding new VMX and VSX instructions, please consider whether they **
// ** are lane-sensitive. If so, they must be added to a switch statement **
// ** in PPCVSXSwapRemoval::gatherVectorInstructions(). **
