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

// *********************************** NOTE ***********************************
// ** When adding new anonymous patterns to this file, please add them to    **
// ** the section titled Anonymous Patterns. Chances are that the existing   **
// ** predicate blocks already contain a combination of features that you    **
// ** are after. There is a list of blocks at the top of the section. If     **
// ** you definitely need a new combination of predicates, please add that   **
// ** combination to the list.                                               **

// ** - Custom PPCISD node definitions                                       **
// ** - Predicate definitions: predicates to specify the subtargets for      **
// **   which an instruction or pattern can be emitted.                      **
// ** - Instruction formats: classes instantiated by the instructions.       **
// **   These generally correspond to instruction formats in section 1.6 of  **
// **   the ISA document.                                                    **
// ** - Instruction definitions: the actual definitions of the instructions  **
// **   often including input patterns that they match.                      **
// ** - Helper DAG definitions: We define a number of dag objects to use as  **
// **   input or output patterns for consciseness of the code.               **
// ** - Anonymous patterns: input patterns that an instruction matches can   **
// **   often not be specified as part of the instruction definition, so an  **
// **   anonymous pattern must be specified mapping an input pattern to an   **
// **   output pattern. These are generally guarded by subtarget predicates. **
// ** - Instruction aliases: used to define extended mnemonics for assembly  **
// **   printing (for example: xxswapd for xxpermdi with 0x2 as the imm).    **

// 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.

  /* 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).

//---------------------------- Anonymous Patterns ----------------------------//
// Predicate combinations are kept in roughly chronological order in terms of
// instruction availability in the architecture. For example, VSX came in with
// ISA 2.06 (Power7). There have since been additions in ISA 2.07 (Power8) and
// ISA 3.0 (Power9). However, the granularity of features on later subtargets
// is finer for various reasons. For example, we have Power8Vector,
// Power8Altivec, DirectMove that all came in with ISA 2.07. The situation is
// similar with ISA 3.0 with Power9Vector, Power9Altivec, IsISA3_0. Then there
// are orthogonal predicates such as endianness for which the order was
// arbitrarily chosen to be Big, Little.
