2017-07-14  Kelvin Nilsen  <kelvin@gcc.gnu.org>

	* config/rs6000/rs6000-c.c (altivec_overloaded_builtins): Add
	array entries to represent __ieee128 versions of the
	scalar_test_data_class, scalar_test_neg, scalar_extract_exp,
	scalar_extract_sig, and scalar_insert_exp built-in functions.
	(altivec_resolve_overloaded_builtin): Add special case handling
	for the __builtin_scalar_insert_exp function, as represented by
	the P9V_BUILTIN_VEC_VSIEDP constant.
	* config/rs6000/rs6000-builtin.def (VSEEQP): Add scalar extract
	exponent support for __ieee128 argument.
	(VSESQP): Add scalar extract signature support for __ieee128
	argument.
	(VSTDCNQP): Add scalar test negative support for __ieee128
	argument.
	(VSIEQP): Add scalar insert exponent support for __int128 argument
	with __ieee128 result.
	(VSIEQPF): Add scalar insert exponent support for __ieee128
	argument with __ieee128 result.
	(VSTDCQP): Add scalar test data class support for __ieee128
	argument.
	(VSTDCNQP): Add overload support for scalar test negative with
	__ieee128 argument.
	(VSTDCQP): Add overload support for scalar test data class
	__ieee128 argument.
	* config/rs6000/vsx.md (UNSPEC_VSX_SXSIG) Replace
	UNSPEC_VSX_SXSIGDP.
	(UNSPEC_VSX_SIEXPQP): New constant.
	(xsxexpqp): New insn for VSX scalar extract exponent quad
	precision.
	(xsxsigqp): New insn for VSX scalar extract significand quad
	precision.
	(xsiexpqpf): New insn for VSX scalar insert exponent quad
	precision with floating point argument.
	(xststdcqp): New expand for VSX scalar test data class quad
	precision.
	(xststdcnegqp): New expand for VSX scalar test negative quad
	precision.
	(xststdcqp): New insn to match expansions for VSX scalar test data
	class quad precision and VSX scalar test negative quad precision.
	* config/rs6000/rs6000.c (rs6000_expand_binop_builtin): Add
	special case operand checking to enforce that second operand of
	VSX scalar test data class with quad precision argument is a 7-bit
	unsigned literal.
	* doc/extend.texi (PowerPC AltiVec Built-in Functions): Add
	prototypes and descriptions of __ieee128 versions of
	scalar_extract_exp, scalar_extract_sig, scalar_insert_exp,
	scalar_test_data_class, and scalar_test_neg built-in functions.
