I have managed to miss the fact that this patch deals with both core file and live register contexts. In that case, I'd like to go one step further, and remove the "configuration" operation from the `RegisterInfoPOSIX_arm64` class as well (by making it a part of the construction). It should be possible to do that by fetching the information needed to determine the registers before the class is instantiated. For the live context, that could be done inside the `CreateHostNativeRegisterContextLinux` function. For the core file context, we could create a similar factory function as well. I.e. move the construction of `RegisterInfoPOSIX_arm64` from ThreadElfCore into some static function inside `RegisterContextCorePOSIX_arm64` -- this function could examine the core data to determine the registers and construct the appropriate info class.
