<pre>
    We ran into this issue with LLVM 20.x that seems similar to https://github.com/llvm/llvm-project/issues/71822.

Unfortunately I'm not able to come up with a minimum reproducible example but the most basic bolt options to trigger this for our case is

```
llvm-bolt "$INPUT_PATH" -o "$OUTPUT_PATH" -data="$PROFILE_PATH" --use-gnu-stack --reorder-functions=hfsort --split-functions --split-all-cold --reorder-blocks=ext-tsp
```

As you can imagine this is quite sensitive to the profile and the pre-bolt code layout, but those things constant it is able to reproduce every time.

```

Sorry I'm not able to provide the profile or a repro, but this looks to me like a case where bolt is splitting the function too far away for the `tbz/tbnz` instruction it's trying to use so hopefully it's enough to start taking a look.

Please let me know if there's more information you need or testing you want us to do on our side.
