	* 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.
