--- Comment #3 from Kang-Che Sung <Explorer09 at gmail dot com> ---
I'm not sure if this helps, but the idea is to recognize three-way comparison
as a special case.
My code was originally written in this ordering:
```c
if (x < c) {
do_action_a();
} else if (x == c) {
do_action_b();
} else {
do_action_c();
}
```
But it should work no differently from this:
```c
if (x == c) {
do_action_b();
} else if (x < c) {
do_action_a();
} else {
do_action_c();
}
```
Or this:
```c
if (x == c) {
do_action_b();
} else if (x <= c) {
do_action_a();
} else {
do_action_c();
}
```
Or even this:
```c
if (x >= c) {
if (x == c) {
do_action_b();
} else {
do_action_c();
}
} else {
do_action_a();
}
```
