@deftypefn {Target Hook} bool TARGET_BUILTIN_SETJMP_FRAME_VALUE ()
This target hook should return an rtx that is used to store
the address of the current frame into the built in @code{setjmp} buffer.
The default value, @code{virtual_stack_vars_rtx}, is correct for most
machines. One reason you may need to define this macro is if
