/* Test gcov block mode. Compiler generates following CFG:
<bb 3>:
if (false_var_4 != 0)
goto <bb 4>;
else
goto <bb 5>;
<bb 4>:
ret_6 = 111;
PROF_edge_counter_10 = __gcov0.UuT[0];
PROF_edge_counter_11 = PROF_edge_counter_10 + 1;
__gcov0.UuT[0] = PROF_edge_counter_11;
<bb 5>:
# ret_1 = PHI <ret_5(3), ret_6(4)>
goto <bb 7>;
It's important not to include <bb 5> to any line as it's actually shared
by both branches of the condition in <bb 3>.
