Synopsis
_mm256_srai_epi32(__m256i a, int imm8);
Description
Shift packed 32-bit integers in "a" right by "imm8" while shifting in sign bits, and store the results in "dst".
Operation
FOR j := 0 to 7
i := j*32
IF imm8[7:0] > 31
dst[i+31:i] := (a[i+31] ? 0xFFFFFFFF : 0x0)
ELSE
dst[i+31:i] := SignExtend32(a[i+31:i] >> imm8[7:0])
FI
ENDFOR
dst[MAX:256] := 0
