[Bug target/16430] New: [3.4/3.5 regression] ICE when returning non-C aggregates larger than 16 bytes

[ebotcazou at gcc dot gnu dot org]

For the Ada testcase:

procedure P is

  type my_array is array (1..6) of Integer;
  A : my_array;

  function Q return my_array is
  begin
    return A;
  end;

begin
  A := Q;
end P;

I get with gcc -m64 on sparc-sun-solaris2.8:

The problem comes from the removing of OImode after GCC 3.2.x.
