__m128d
_mm_unpackhi_pd (
__m128d
a
,
__m128d
b
)
(uses UNPCKHPD
)
Interleaves the upper DP FP values of a
and b
.
r0 := a1
r1 := b1
__m128d
_mm_unpacklo_pd (
__m128d
a
,
__m128
d
b
)
(uses UNPCKLPD
)
Interleaves the lower DP FP values of a
and b
.
r0 := a0
1 := b0
int _mm_movemask_pd (
__m128d
a)
(uses MOVMSKPD
)
Creates a two bit mask from the sign bits of the two DP FP values of a
.
r := sign(a1) <<
1 | sign(a0)
__m128d
_mm_shuffle_pd (
__m128d
a
,
__m128d
b
,
int
i
)
(uses SHUFPD
)
Selects two specific DP FP values from a
and b
,
based on the mask i
. The
mask must be an immediate. See Macro Function
for Shuffle for a description of the shuffle semantics.
