Synopsis

int16x2 __ssax(int16x2 val1,
               int16x2 val2);

Description

__ssax inserts a SSAX instruction. __ssax returns the 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. This operation sets the GE bits.
