Instruction
VPRORD xmm, xmm, imm8
Synopsis
 _mm_ror_epi32(__m128i a, const int imm8);
Description
Rotate the bits in each packed 32-bit integer in "a" to the right by the number of bits specified in "imm8", and store the results in "dst".
Operation
DEFINE RIGHT_ROTATE_DWORDS(src, count_src) {
	count := count_src % 32
	RETURN (src >>count) OR (src << (32 - count))
}
FOR j := 0 to 3
	i := j*32
	dst[i+31:i] := RIGHT_ROTATE_DWORDS(a[i+31:i], imm8[7:0])
ENDFOR
dst[MAX:128] := 0
