Subject: 	* config/arm/arm.c (arm_preferred_simd_mode): Check
X-Git-Tag: upstream/4.9.2~17886
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=859baaaf41afb8c41be1996b718701106603f2af;p=platform%2Fupstream%2Flinaro-gcc.git

	* config/arm/arm.c (arm_preferred_simd_mode): Check
	TARGET_NEON_VECTORIZE_DOUBLE instead of
	TARGET_NEON_VECTORIZE_QUAD.
	(arm_autovectorize_vector_sizes): Likewise.
	* config/arm/arm.opt (mvectorize-with-neon-quad): Make inverse
	mask of mvectorize-with-neon-double.  Add RejectNegative.
	(mvectorize-with-neon-double): New.
