Wave32-only or similar, with semantics that it gets erased by clang without warning on wave64. Would be as if that function never existed on wave64 targets. Might need it to apply to objects as well, depending on how much of this stuff device-libs contains.

device libs may be linked in by other programs or libraries, e.g. comgr.
