There would have to be a macro wrapping the inline function, with an appropriate cast to preserve the function pointer type.Correct, but it's localized in one file per architecture, right? So, not a big problem?
Agreed, I don't see a problem with that. Just the inline function would have to be architecture-specific. These days, we probably don't even need custom inline assembly anymore (just the architecture-specified way to access thread-local state).
