reduced to one file:
static inline const unsigned &max1(const unsigned &t, const unsigned &t1)
{
return t > t1 ? t : t1;
}
long long int c = 42;
int var_20 = 0;
int var_22 = 0;
short arr_32 [13];
char arr_45 [69];
void test(int a, unsigned b, long long *c) __attribute__((noipa));
void test(int a, unsigned b, long long *c) {
for (short d = 0; d < 13; d++) {
for (int e = 0; e < a; e += 3)
var_20 = 0;
if (max1(b, unsigned((short)b))) {
arr_32[d] = 0;
var_22 = *c;
}
for (unsigned f = 0; f < 69; f += 4)
arr_45[f] = 0;
}
}
int main() {
test(-545750584, 1144022456U, &c);
if (var_22 != 42)
__builtin_abort();
return 0;
}
Confirmed.
