[Bug middle-end/29864] Folding conversion unsigned long long to float

[rguenth at gcc dot gnu dot org]

------- Comment #2 from rguenth at gcc dot gnu dot org  2008-02-04 15:52 -------
A testcase would probably be sth along the lines of

extern void abort (void);
void __attribute__((noinline)) foo (unsigned long long x)
{
  float uf = x;
  float sf = (signed long long)x;
  if (uf == sf)
    abort ();
}
int main()
{
  foo (-1);
  return 0;
}

with the right target and soft-float (any suggestion?).
