Function core::arch::x86_64::_mm_extract_si64 1.27.0[−][src]
pub unsafe fn _mm_extract_si64(x: __m128i, y: __m128i) -> __m128iThis is supported on x86-64 and target feature
sse4a only.Expand description
Extracts the bit range specified by y from the lower 64 bits of x.
The [13:8] bits of y specify the index of the bit-range to extract. The
[5:0] bits of y specify the length of the bit-range to extract. All
other bits are ignored.
If the length is zero, it is interpreted as 64. If the length and index
are zero, the lower 64 bits of x are extracted.
If length == 0 && index > 0 or lenght + index > 64 the result is
undefined.
