pub unsafe fn _mm_shuffle_epi8(a: __m128i, b: __m128i) -> __m128iAvailable on (x86 or x86-64) and target feature
ssse3 and x86-64 only.Expand description
Shuffles bytes from a according to the content of b.
The last 4 bits of each byte of b are used as addresses
into the 16 bytes of a.
In addition, if the highest significant bit of a byte of b
is set, the respective destination byte is set to 0.
Picturing a and b as [u8; 16], _mm_shuffle_epi8 is
logically equivalent to:
