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

  /* Variable element number (BE and LE patterns must be specified separately)
     This is a rather involved process.

     Conceptually, this is how the move is accomplished:
     1. Identify which doubleword contains the element
     2. Shift in the VMX register so that the correct doubleword is correctly
        lined up for the MFVSRD
     3. Perform the move so that the element (along with some extra stuff)
        is in the GPR
     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).
