// *********************************** 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().                      **

// Instruction form with a single input register for instructions such as

// operands (such as loads) to an instruction will perform both chained
// operations rather than coalescing them into a single register - even though
// the source memory location is the same. This simply forces the instruction
// to use the same register for both inputs.
// For example, an output DAG such as this:
//   (XXPERMDI (LXSIBZX xoaddr:$src), (LXSIBZX xoaddr:$src ), 0))
// would result in two load instructions emitted and used as separate inputs
// to the XXPERMDI instruction.

     3. Perform the move so that the element (along with some extra stuff)

     4. Right shift within the GPR so that the element is right-justified

     Of course, the index is an element number which has a different meaning
     on LE/BE so the patterns have to be specified separately.

     Note: The final result will be the element right-justified with high
           order bits being arbitrarily defined (namely, whatever was in the
           vector register to the left of the value originally).
