[Bug middle-end/39932] [4.5 Regression] Revision 146831 caused many test failures



------- Comment #3 from sje at cup dot hp dot com  2009-04-28 21:10 -------
There error I get on cc.c-torture/execute/20050604-1.c and
gcc.dg/torture/pr21817-1.c with optimization level 1 or greater is:

x.c:6: error: invalid expression for min lvalue
D.2000_6 = BIT_FIELD_REF <{ 1.0e+9, 1.0e+9, 1.0e+9, 1.0e+9 }, 64, 64>;

pr21817.c is pretty small already but I did cut it down to:

typedef float v4sf __attribute__((vector_size(16)));
v4sf value;
void foo(void)
{
      value += (v4sf){1e9f,1e9f,1e9f,1e9f};
}

It is not clear if we have generated bad gimple or if the verifier is wrong.
