Parameters

a A 64-bit integer vector containing the values to be shuffled.

n An immediate value containing an 8-bit value specifying which elements to copy from a. The destinations within the 64-bit destination are assigned values as follows:
Bits [1:0] are used to assign values to bits [15:0] in the destination.

10: assigned from bits [47:32] of a.
11: assigned from bits [63:48] of a.

Create a 128-bit vector of [4 x float] with undefined values.

This intrinsic has no corresponding instruction.

Returns: A 128-bit vector of [4 x float] containing undefined values.

◆ _mm_unpackhi_ps()

static __inline__ __m128 __DEFAULT_FN_ATTRS _mm_unpackhi_ps	(	__m128	__a,
		__m128	__b
	)

static

Unpacks the high-order (index 2,3) values from two 128-bit vectors of [4 x float] and interleaves them into a 128-bit vector of [4 x float].

This intrinsic corresponds to the VUNPCKHPS / UNPCKHPS instruction.

Parameters

__a	A 128-bit vector of [4 x float]. Bits [95:64] are written to bits [31:0] of the destination. Bits [127:96] are written to bits [95:64] of the destination.
__b	A 128-bit vector of [4 x float]. Bits [95:64] are written to bits [63:32] of the destination. Bits [127:96] are written to bits [127:96] of the destination.

Returns: A 128-bit vector of [4 x float] containing the interleaved values.

◆ _mm_unpacklo_ps()

static __inline__ __m128 __DEFAULT_FN_ATTRS _mm_unpacklo_ps	(	__m128	__a,
		__m128	__b
	)

static

Unpacks the low-order (index 0,1) values from two 128-bit vectors of [4 x float] and interleaves them into a 128-bit vector of [4 x float].

This intrinsic corresponds to the VUNPCKLPS / UNPCKLPS instruction.

Parameters

__a	A 128-bit vector of [4 x float]. Bits [31:0] are written to bits [31:0] of the destination. Bits [63:32] are written to bits [95:64] of the destination.
__b	A 128-bit vector of [4 x float]. Bits [31:0] are written to bits [63:32] of the destination. Bits [63:32] are written to bits [127:96] of the destination.

Returns: A 128-bit vector of [4 x float] containing the interleaved values.

◆ _mm_xor_ps()

static __inline__ __m128 __DEFAULT_FN_ATTRS _mm_xor_ps	(	__m128	__a,
		__m128	__b
	)

static

Performs a bitwise exclusive OR of two 128-bit vectors of [4 x float].

This intrinsic corresponds to the VXORPS / XORPS instructions.

Parameters

__a	A 128-bit vector of [4 x float] containing one of the source operands.
__b	A 128-bit vector of [4 x float] containing one of the source operands.

Returns: A 128-bit vector of [4 x float] containing the bitwise exclusive OR of the values between both operands.
