2018-06-22  Kelvin Nilsen  <kelvin@gcc.gnu.org>

	* config/rs6000/rs6000-c.c (altivec_overloaded_builtins): Change
	behavior of vec_pack (vector double, vector double) to match
	behavior of vec_float2 (vector double, vector double).

gcc/testsuite/ChangeLog:

2018-06-22  Kelvin Nilsen  <kelvin@gcc.gnu.org>

	* gcc.target/powerpc/builtins-3-p8.c (test_pack_float): Remove
	this test.
	* gcc.target/powerpc/builtins-9.c: New test.
	* gcc.target/powerpc/fold-vec-pack-double.c: Modify dg directives
	to expect different code generation on big-endian vs.
	little-endian targets.
