I ran into an interesting issue while doing this. Right now the expand
pass calls construct_exit_block (which calls expand_function_end) before
it calls expand_stack_alignment. That means that crtl->drap_reg, etc
are not yet set up when
saved copy is used by the unwind info?
I don't see any indication that the unwind library knows if a stack has
been dynamically realigned and I don't see where unwind makes use of
this value.
