[Bug middle-end/42196] New: ICE when SRAing partial assigments to complex number

[jamborm at gcc dot gnu dot org]

Not very surprisingly, I get ICEs at tree-sra.c:2148 when compiling
these two examples with the current trunk at -O[123] on x86-64-linux:

======================================================================
union U
{
  double d;
  __complex__ int c;
};

double gd;
extern double bar (union U);

double foo (int b, double d, int c1, int c2)
{
  union U u;
  double r;

  if (b)
    {
      u.d = d;
      r = u.d;
    }
  else
    {
      __real__ u.c = c1;
      __imag__ u.c = c2;
      r = bar (u);
    }

  return r;
}
======================================================================
union U
{
  __complex__ int ci;
  __complex__ float cf;
};

float gd;
extern float bar (union U);

float foo (int b, double f1, double f2, int c1, int c2)
{
  union U u;
  double r;

  if (b)
    {
      __real__ u.cf = f1;
      __imag__ u.cf = f2;
    }
  else
    {
      __real__ u.ci = c1;
      __imag__ u.ci = c2;
    }

  r = bar (u);
  return r;
}
======================================================================

Hopefully I know what needs to be done.

Martin

------- Comment #1 from jamborm at gcc dot gnu dot org  2009-11-27 22:22 -------
Just for the record, this also fails, for similar reasons like the
second testcase above:

union U
{
  __complex__ int ci;
  __complex__ float cf;
};

float gd;
extern float bar (float, float);

float foo (int b, union U u)
{
  float f1, f2, r;

  if (b)
    {
      f1 = __real__ u.cf;
      f1 = __imag__ u.cf;
    }
  else
    {
      f1 = __real__ u.ci;
      f1 = __imag__ u.ci;
    }

  r = bar (f1, f2);
  return r;
}
