      19  /* A very dirty trick: gcc emits references to __divdi3, __udivdi3,
      20     __moddi3, and __umoddi3.  These functions are exported and
      21     therefore we get PLTs.  Unnecessarily so.  Changing gcc is a big
      22     task which might not be worth it so we play tricks with the
      23     assembler.
      24     Note: in_divdi3_c is only used to avoid symbol alias on divdi3
      25     build itself.  */
