       4  /* On MIPS targets that support conditional moves, the optimal
       5     implementation of this function is:
       6  
       7  	l[wd] tmp,p
       8  	li $2,2
       9  	jr $31
      10  	movz $2,$0,tmp
      11  
      12     After if-conversion, we have a conditional move into a pseudo P
      13     followed a copy of P into the return register ($2).  P is associated
      14     with xyzzy, so if-conversion is behaving as expected, and has not lost
      15     the variable association.  The destination of the second instruction
      16     is associated with the function return value.  Combine then combines
      17     these two instructions, removing the last use of P and xyzzy.
      18  
      19     Everything is behaving as expected in this scenario, so we avoid
      20     using conditional moves for this test.
