--- Comment #21 from Dominik Vogt <vogt at linux dot vnet.ibm.com> --- Trying to write a test case for Power, I was unable to force the bug to show in the first place. Although I can force the addresses used into different registers, dead store elimination on power does not kill the first store. ==> No test case for Power.
