gcc/ChangeLog:

2017-11-13  Carl Love  <cel@us.ibm.com>

	* config/rs6000/rs6000-c.c (altivec_overloaded_builtins):
	Add support for builtins:
	unsigned int vec_first_{,miss}_match_{,or_eos}index,
	vector {un,}signed {char,int,short},
	vector {un,}signed {char,int,short}) arguments.
	* config/rs6000/rs6000-builtin.def (VFIRSTMATCHINDEX,
	VFIRSTMATCHOREOSINDEX, VFIRSTMISMATCHINDEX, VFIRSTMISMATCHOREOSINDEX):
	Add BU_P9V_AV_2 expansions for the builtins.
	* config/rs6000/altivec.h (vec_first_match_index,
	vec_first_mismatch_index, vec_first_match_or_eos_index,
	vec_first_mismatch_or_eos_index): Add #defines for the builtins.
	* config/rs6000/rs6000-protos.h (bytes_in_mode): Add
	new extern declaration.
	* config/rs6000/rs6000.c (bytes_in_mode): Add new function.
	* config/rs6000/vsx.md (first_match_index_<mode>,
	first_match_or_eos_index_<mode>, first_mismatch_index_<mode>,
	first_mismatch_or_eos_index_<mode>): Add define expand.
	(vctzlsbb_<mode>): Add mode field to define_insn for vctzlsbb.
	* doc/extend.texi: Update the built-in documenation file for the new
	built-in functions.

gcc/testsuite/ChangeLog:

2017-11-13  Carl Love  <cel@us.ibm.com>

	* gcc.target/powerpc/builtins-6-p9-runnable.c: Add new runnable test.
