gcc/ChangeLog:

2018-04-10  Kelvin Nilsen  <kelvin@gcc.gnu.org>

	* config/rs6000/rs6000-c.c (altivec_overloaded_builtins): Remove
	erroneous entries for
	"vector int vec_ldl (int, long int *)", and
	"vector unsigned int vec_ldl (int, unsigned long int *)".
	Add comments and entries for
	"vector bool char vec_ldl (int, bool char *)",
	"vector bool short vec_ldl (int, bool short *)",
	"vector bool int vec_ldl (int, bool int *)",
	"vector bool long long vec_ldl (int, bool long long *)",
	"vector pixel vec_ldl (int, pixel *)",
	"vector long long vec_ldl (int, long long *)",
	"vector unsigned long long vec_ldl (int, unsigned long long *)".
	* config/rs6000/rs6000.c (rs6000_init_builtins): Initialize new
	type tree bool_long_long_type_node and correct definition of
	bool_V2DI_type_node to make reference to this new type tree.
	(rs6000_mangle_type): Replace erroneous reference to
	bool_long_type_node with bool_long_long_type_node.
	* config/rs6000/rs6000.h (enum rs6000_builtin_type_index): Add
	comments to emphasize sign distinctions for char and int types and
	replace RS6000_BTI_bool_long constant with
	RS6000_BTI_bool_long_long constant.  Also add comment to restrict
	use of RS6000_BTI_pixel.
	(bool_long_type_node): Remove this macro definition.
	(bool_long_long_type_node): New macro definition

gcc/testsuite/ChangeLog:

	* gcc.target/powerpc/vec-ldl-1.c: New test.
	* gcc.dg/vmx/ops-long-1.c: Correct test programs to reflect
	corrections to ABI implementation.
