Synopsis

uint16x2 __uhsub16(uint16x2 val1,
                   uint16x2 val2);

Description

__uhsub16 inserts a UHSUB16 instruction. __uhsub16 returns the 16-bit unsigned equivalent of

• res[0] = (val1[0] - val2[0])/2
• res[1] = (val1[1] - val2[1])/2
  
  where [0] is the lower 16 bits and [1] is the upper 16 bits.
