_Complex double c;
_Complex double foo(void)
{
_Complex double *cp = &c;
__real c = __imag c;
return *cp;
}
has in alias1:
foo ()
{
complex double * cp;
complex double D.1527;
double D.1526;
<bb 2>:
cp_1 = &c;
# VUSE <SFT.0_2>;
D.1526_3 = IMAGPART_EXPR <c>;
# SFT.1_5 = V_MUST_DEF <SFT.1_4>;
REALPART_EXPR <c> = D.1526_3;
# VUSE <SFT.1_5>;
D.1527_6 = *cp_1;
# <retval>_8 = V_MUST_DEF <<retval>_7>;
<retval> = D.1527_6;
# VUSE <<retval>_8>;
return <retval>;
}
note how D.1527_6 = *cp_1; misses VUSE <SFT.0_2>
