Because they *don't* conflict with stack_pointer_rtx.
Do read the thread Dale indicated.
I did, but some things aren't clear, at least in the comments that
were added. What was added is a (clobber (mem)). It's true that the
address was stack_pointer_rtx, but nothing in the comments suggest
that the form of the address is relevant. Instead, they imply that
it was the mere addition of the CLOBBER that was sufficient.
Am I missing something?
