New Revision: 179870

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=179870
Log:
	* config/i386/i386.md (UNSPEC_VPERMDI): Remove.
	* config/i386/i386.c (ix86_expand_vec_perm): Handle
	V16QImode and V32QImode for TARGET_AVX2.
	(MAX_VECT_LEN): Increase to 32.
	(expand_vec_perm_blend): Add support for 32-byte integer
	vectors with TARGET_AVX2.
	(valid_perm_using_mode_p): New function.
	(expand_vec_perm_pshufb): Add support for 32-byte integer
	vectors with TARGET_AVX2.
	(expand_vec_perm_vpshufb2_vpermq): New function.
	(expand_vec_perm_vpshufb2_vpermq_even_odd): New function.
	(expand_vec_perm_even_odd_1): Handle 32-byte integer vectors
	with TARGET_AVX2.
	(ix86_expand_vec_perm_builtin_1): Try expand_vec_perm_vpshufb2_vpermq
	and expand_vec_perm_vpshufb2_vpermq_even_odd.
	* config/i386/sse.md (VEC_EXTRACT_EVENODD_MODE): Add for TARGET_AVX2
	32-byte integer vector modes.
	(vec_pack_trunc_<mode>): Use VI248_AVX2 instead of VI248_128.
	(avx2_interleave_highv32qi, avx2_interleave_lowv32qi): Remove pasto.
	(avx2_pshufdv3, avx2_pshuflwv3, avx2_pshufhwv3): Generate
	4 new operands.
	(avx2_pshufd_1, avx2_pshuflw_1, avx2_pshufhw_1): Don't use
	match_dup, instead add 4 new operands and require they have
	right cross-lane values.
	(avx2_permv4di): Change into define_expand.
	(avx2_permv4di_1): New instruction.
	(avx2_permv2ti): Use nonimmediate_operand instead of register_operand
	for "xm" constrained operand.
	(VEC_PERM_AVX2): Add V32QI and V16QI for TARGET_AVX2.
