FWIW, here is the last SSA form I get with vops.
foo (p)
{
int D.1241;
int global.0;
int D.1239;
<bb 0>:
# VUSE <global_3>;
D.1239_2 = p_1->c;
if (D.1239_2 != 0) goto <L2>; else goto <L0>;
<L0>:;
# VUSE <global_3>;
global.0_4 = global;
D.1241_5 = global.0_4 + 1;
# global_6 = V_MUST_DEF <global_3>;
global = D.1241_5;
# VUSE <global_6>;
D.1239_7 = p_1->c;
if (D.1239_7 == 0) goto <L1>; else goto <L2>;
<L1>:;
# global_8 = V_MAY_DEF <global_6>;
bar () [tail call];
<L2>:;
return;
}
