[Bug middle-end/38271] [4.4 Regression] Spurious / missing "... used uninitialized in this function" warning

[rguenth at gcc dot gnu dot org]

------- Comment #3 from rguenth at gcc dot gnu dot org  2008-11-26 10:00 -------
Doesn't happen on 64bit x86_64.  Testcase which doesn't warn with 4.3:

struct xxx {
    short a;
    short b;
    void *c;
};

void bar(struct xxx);

void foo(struct xxx *p, int i)
{
  struct xxx s = *p;
  if (s.a) i++;
  bar(s);
}

but indeed, SRA does bullshit here, cost-wise and correctness-wise.
