Synopsis
_mm_shrdv_epi16(__m128i a, __m128i b, __m128i c);
Description
Concatenate packed 16-bit integers in "b" and "a" producing an intermediate 32-bit result. Shift the result right by the amount specified in the corresponding element of "c", and store the lower 16-bits in "dst".
Operation
FOR j := 0 to 7
i := j*16
dst[i+15:i] := ((b[i+15:i] << 16)[31:0] | a[i+15:i]) >> (c[i+15:i] & 15)
ENDFOR
dst[MAX:128] := 0
