gcc/ChangeLog:

2018-06-20  Kelvin Nilsen  <kelvin@gcc.gnu.org>

	* config/rs6000/rs6000-c.c (altivec_overloaded_builtins): Change
	behavior of vec_packsu (vector unsigned long long, vector unsigned
	long long) to match behavior of vec_packs with same signature.

gcc/testsuite/ChangeLog:

2018-06-20  Kelvin Nilsen  <kelvin@gcc.gnu.org>

	* gcc.target/powerpc/builtins-1.c: Adjust dg directives to scan
	for vpkudus in place of vpksdus.
	* gcc.target/powerpc/builtins-3-p8.c: Likewise.
