The only guaranteed way is to write
ADR r0, 0f
ORR r0, r0, #1
BX r0
Note, you should use ORR (not ADD) so that it is guaranteed that the bottom bit

I think it shouldn't be allowed. Consider:
rsXX1 .req r0

.unreq rsXX1
What value does rsXX2 have now? What if rsXX1 were further redefined?

This is to be expected. In ELF, local labels have type STT_NOTYPE, and these
can't be used for interworking purposes (only labels of type STT_FUNC can).
