--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
As for the .DEFERRED_INIT not being DSEd when it isn't used, cvise reduced
testcase is e.g.

int a;
int foo (void);
int bar (void);

void
baz (void)
{
  int *b[6];
  if (foo ())
    a |=3D bar ();
}

while with a |=3D 1; instead dse1 removes it.  Richi, any thoughts on that?
Of course, the real bug is on the x86 backend side.=
