General question, why do these need to be guarded with `SANITIZER_AMDHSA`? They're just forward declarations, and I think in general sanitizers are intended to be compiled for whatever can be supported. I am curious what our discriminator is here, we either force the uesr to pass `ON` for this, or do it by default and add a few KB to a static library on Linux. Static linking semantics should mean that we don't link anything that's not actually used, as long as these are properly separated (part of why I said that everything needs to be in its own file more or less).
