Updated test case:
int main();
int a[] = {
2.0 ? 0 : 1,
(_Bool)2.0,
!2.0,
2.0,
(char)500,
main ? 0 : 1, // function pointer is always true
(int)main + (int)1e9, // be sure the result is above 1.000.000.000
(int)main / 2, // here must be compile-time error, tcc can compile it
sin(1) ? 0 : 1, // here must be compile-time error, tcc can compile it
};
int main()
{
int i;
for(i=0; i<sizeof(a)/sizeof(*a); i++) printf("%d ", a[i]);
printf("\n");
}
