gcc/ChangeLog:

2017-07-11  Carl Love  <cel@us.ibm.com>

	* config/rs6000/rs6000-c.c: Add support for builtins
	vector unsigned int vec_parity_lsbb (vector signed int);
	vector unsigned int vec_parity_lsbb (vector unsigned int);
	vector unsigned __int128 vec_parity_lsbb (vector signed __int128);
	vector unsigned __int128 vec_parity_lsbb (vector unsigned __int128);
	vector unsigned long long vec_parity_lsbb (vector signed long long);
	vector unsigned long long vec_parity_lsbb (vector unsigned long long);
	* config/rs6000/rs6000-builtin.def (VPARITY_LSBB): Add BU_P9V_OVERLOAD1.
	* config/rs6000/altivec.h (vec_parity_lsbb): Add define.
	* doc/extend.texi: Update the built-in documentation file for the
	new built-in functions.

gcc/testsuite/ChangeLog:

2017-07-11  Carl Love  <cel@us.ibm.com>

	* gcc.target/powerpc/builtins-2-p9-runnable.c: Add new file with
	test cases for the builtins.
