Hi,

This patch adds a few more vector interfaces listed in the ELFv2 ABI
v1.1:  missing flavors of vec_madd, vec_pmsum_be, and vec_shasigma_be.
Existing tests have been updated to check for correct code gen.  Tested
on powerpc64le-unknown-linux-gnu with no regressions.  Ok for trunk?

Thanks,
Bill


[gcc]

2015-08-20  Bill Schmidt  <wschmidt@linux.vnet.ibm.com>

	* config/rs6000/altivec.h (vec_pmsum_be): New #define.
	(vec_shasigma_be): New #define.
	* config/rs6000/rs6000-builtin.def (VPMSUMB): New BU_P8V_AV2_2.
	(VPMSUMH): Likewise.
	(VPMSUMW): Likewise.
	(VPMSUMD): Likewise.
	(VPMSUM): New BU_P8V_OVERLOAD_2.
	* config/rs6000/rs6000-c.c (altivec_overloaded_builtins): New
	entries for VEC_MADD and VEC_VPMSUM.

[gcc/testsuite]

2015-08-20  Bill Schmidt  <wschmidt@linux.vnet.ibm.com>

	* gcc.target/powerpc/altivec-35.c (foo): Add tests for vec_madd.
	* gcc.target/powerpc/p8vector-builtin-8.c (foo): Add tests for
	vec_vpmsum_be and vec_shasigma_be.
