Ah, I see. That's a really nice idea. I'm not sure it would quite give the accuracy I need here though — it seems like "arm64" isn't an auto-detected $(ARCH_DIR) option out of the box, and there isn't any way to single out ARMv7 dependent stuff specifically either. Also, I'm not sure how a generic fallback would best be established in a system like that. For the time being, I'll split the architecture-dependent stuff into separate header files and then simply conditionally include these based on the same macros I'm using at the moment (__ARM_ARCH, etc.). Would that be alright?
