/* Asm for procedure li_stw().

   The purpose of this function is to verify that GDB does not
   include the li insn as part of the function prologue (only part
   of the prologue if part of a pair of insns saving vector registers).
   Similarly, GDB should not include the stw insn following the li insn,
   because the source register is not used for parameter passing.  */
