extern __m256i _mm256_inserti128_si256(__m256i a, __m128i b, const int mask);
Arguments
a
integer source vector
b
integer source vector
mask
integer constant specifying offset
Description
Inserts 128-bits of packed integer data from the second source operand (third operand) into the destination operand (first operand) at a 128-bit offset from
imm8[0]
. The remaining portions of the destination are written by the corresponding fields of the first source operand (second operand). The high 7 bits of the immediate are ignored.
