They clear r0 to zero and store that value at a location of -64
relative to the stack pointer.  It looks to me like that location is
the place in the stack frame where a pointer to the (non-existent)
parent stack frame should go, so that's where  they are putting the
zero/null value to indicate that there is no parent.
