I believe that is the preferred way, rather than macros.
The macros are yet another thing that would need to be undone if we ever
start supporting multiple targets in the same binary.
I don't see any advantages of introducing the macros.
Ah, I understand, thank you. We debated a bit internally about whether
one was better than the other, so thank you for the rationale!
By the way, are there “official” plans to support multiple targets in
the same binary at some point, by the way? It’s the first time I hear
about it (that would be nice!).
It's pie in the sky right now, but it's something many of us want to see
happen. To that end we're trying to steer away from certain problematic
idioms (like using macros to conditionalize behavior) towards schemes
that would work in that world (hooks).
One good way to start thinking about this stuff is what would need to
change to support a world where the target (or front-end) were a DSO and
replaceable.
