Synopsis

uint16x2 __uasx(uint16x2 val1,
                uint16x2 val2);

Description

__uasx inserts a UASX instruction. __uasx returns the 16-bit unsigned equivalent of

• res[0] = val1[0] - val2[1]
• res[1] = val1[1] + val2[0]
  
  where [0] is the lower 16 bits and [1] is the upper 16 bits. The GE bits of the APSR are set.
