I had a very long answer, but just before sending it, I deleted it. We should return to beginning.

I saying that ‘ .globl foo; foo: adr r0, foo" is absolutely valid code if is used in statically compiled executable.
By words, is absolutely OK to take reference to global symbol by 'adr' pseudo instruction if given object is linked to pure static environment.

You saying that this code snippet is undefined. So imagine I'm an absolute newcomer and tell me exactly why it's wrong and what isn't exactly defined.
If you give me single real evidence I'll apologize and immediately send the patch to FreeBSD.

I hope that this is fair offer right?
