--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Ick.  And DSEs "new" redundant store removal code is completely buggy in this
regard as well...  adding noipa to foo makes the testcase still fail when FRE
is fixed.  So fixing that as well... (and then there's still DOM as well,
with -fno-tree-dse which would delete the dead store).
