[Undef](https://llvm.org/docs/LangRef.html#undefined-values) is now deprecated and should only be used in the rare cases where no replacement is possible. For example, a load of uninitialized memory yields `undef`. You should use `poison` values for placeholders instead.
In tests, avoid using `undef` and having tests that trigger undefined behavior. If you need an operand with some unimportant value, you can add a new argument to the function and use that instead.
For example, this is considered a bad practice:
```llvm
define void @fn() {
...
br i1 undef, ...
}
```
Please use the following instead:
```llvm
define void @fn(i1 %cond) {
...
br i1 %cond, ...
}
```
Please refer to the [Undefined Behavior Manual](https://llvm.org/docs/UndefinedBehavior.html) for more information.
