    * config/rs6000/constraints.md (wD constraint): New constraint to
    match the constant integer to get the top DImode/DFmode out of a
    vector in a VSX register.

    * config/rs6000/predicates.md (vsx_scalar_64bit): New predicate to
    match the constant integer to get the top DImode/DFmode out of a
    vector in a VSX register.

    * config/rs6000/rs6000-builtins.def (VBPERMQ): Add vbpermq builtin
    for ISA 2.07.

    * config/rs6000/rs6000-c.c (altivec_overloaded_builtins): Add
    vbpermq builtins.

    * config/rs6000/rs6000.c (rs6000_debug_reg_global): If
    -mdebug=reg, print value of VECTOR_ELEMENT_SCALAR_64BIT.

    * config/rs6000/vsx.md (vsx_extract_<mode>, V2DI/V2DF modes):
    Optimize vec_extract of 64-bit values, where the value being
    extracted is in the top word, where we can use scalar
    instructions.  Add direct move and store support.  Combine the big
    endian/little endian vector select load support into a single
    insn.
    (vsx_extract_<mode>_internal1): Likewise.
    (vsx_extract_<mode>_internal2): Likewise.
    (vsx_extract_<mode>_load): Likewise.
    (vsx_extract_<mode>_store): Likewise.
    (vsx_extract_<mode>_zero): Delete, big and little endian insns are
    combined into vsx_extract_<mode>_load.
    (vsx_extract_<mode>_one_le): Likewise.

    * config/rs6000/rs6000.h (VECTOR_ELEMENT_SCALAR_64BIT): Macro to
    define the top 64-bit vector element.

    * doc/md.texi (PowerPC and IBM RS6000 constraints): Document wD
    constraint.

    PR target/60672
    * config/rs6000/altivec.h (vec_xxsldwi): Add missing define to
    enable use of xxsldwi and xxpermdi builtin functions.
    (vec_xxpermdi): Likewise.

    * doc/extend.texi (PowerPC AltiVec/VSX Built-in Functions):
    Document use of vec_xxsldwi and vec_xxpermdi builtins.

    * gcc.target/powerpc/p8vector-vbpermq.c: New test to test the
    vbpermq builtin.

    * gcc.target/powerpc/vsx-extract-1.c: New test to test VSX
    vec_select optimizations.
    * gcc.target/powerpc/vsx-extract-2.c: Likewise.
    * gcc.target/powerpc/vsx-extract-3.c: Likewise.

    PR target/60672
    * gcc.target/powerpc/pr60676.c: New file, make sure xxsldwi and
    xxpermdi builtins are supported.
