Synopsis
uint8x4 __uqsub8(uint8x4 val1,
uint8x4 val2);
Description
__uqsub8 inserts a UQSUB8 instruction. __uqsub8 returns the 8-bit unsigned 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.
