Synopsis
int8x4 __qadd8(int8x4 val1,
int8x4 val2);
Description
__qadd8 inserts a QADD8 instruction. __qadd8 returns the 8-bit signed saturated equivalent of
- res[0] = val1[0] + val2[0]
- res[1] = val1[1] + val2[1]
- res[2] = val1[2] + val2[2]
- res[3] = val1[3] + val2[3]
where [0] is the lower 8 bits and [3] is the upper 8 bits.
