> But you get compile-time warnings for that (-Wswitch), no?
For:
cat enum.c
enum values
{
A = 1000,
B = 30,
C = 100
};
int main(int argc, char **argv)
{
enum values x = (enum values)argc;
if (x == 12345)
return 1;
switch (x)
{
case A:
return 1;
case B:
return 1;
case C:
return 2;
case 123:
return 3;
default:
return 4;
}
}
I only have warning for 'case 123':
gcc -fsanitize=enum enum.c -Wall
enum.c: In function ‘main’:
enum.c:22:5: warning: case value ‘123’ not in enumerated type ‘enum values’
[-Wswitch]
case 123:
^~~~
But one could also produce warning for the if comparison and default bb in the
switch statement.
