Options

[2/2] Vectorise lroundf, lfloorf, lceilf using the new ARMv8-A vcvt* instructions. 

	PR target/62275
	* config/arm/neon.md
	(neon_vcvt<NEON_VCVT:nvrint_variant><su_optab><VCVTF:mode>
	<v_cmp_result>): New pattern.
	* config/arm/iterators.md (NEON_VCVT): New int iterator.
	* config/arm/arm_neon_builtins.def (vcvtav2sf, vcvtav4sf, vcvtauv2sf,
	vcvtauv4sf, vcvtpv2sf, vcvtpv4sf, vcvtpuv2sf, vcvtpuv4sf, vcvtmv2sf,
	vcvtmv4sf, vcvtmuv2sf, vcvtmuv4sf): New builtin definitions.
	* config/arm/arm.c (arm_builtin_vectorized_function): Handle
	BUILT_IN_LROUNDF, BUILT_IN_LFLOORF, BUILT_IN_LCEILF.
