--- Comment #4 from Peter Bergner <bergner at gcc dot gnu.org> ---
Confirmed with the following creduced test case:
bergner@genoa:~/gcc/BUGS/GNU_SPE$ cat pr78458.i
long double a, f, g, h, i;
long double b, c, d, k;
_Complex
foo (long double p1)
{
_Complex e;
a = k * h;
b = p1 * g;
if (__builtin_expect(c, 0)
&& __builtin_expect(d, 0))
{
long double j = __builtin_expect(k, 0);
if (__builtin_expect(j, 0))
p1 = __builtin_copysignl(1, p1);
a = b = b - i;
if (f)
d = h + p1 * g;
}
e = c;
__imag__ e = d;
return e;
}
