--- 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.
