--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
IRA has the first real difference:
Will split live ranges of parameters at BB 8
      Creating newreg=122 from oldreg=121
scanning new insn with uid = 140.
Split live-range of register (reg:DI 121)
rescanning insn with uid = 84.


vs:
Will split live ranges of parameters at BB 7
      Creating newreg=122 from oldreg=121
scanning new insn with uid = 223.
Split live-range of register (reg:DI 121)
rescanning insn with uid = 142.
rescanning insn with uid = 161.
