Synopsis

uint16x2 __uhasx(uint16x2 val1,
                 uint16x2 val2);

Description

__uhasx inserts a UHASX instruction. __uhasx returns the 16-bit unsigned equivalent of

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