+ Note that __sigsetjmp() did NOT flush the register stack. Instead,
+ we do it here since __longjmp() is usually much less frequently
+ invoked than __sigsetjmp(). The only difficulty is that __sigsetjmp()
+ didn't (and wouldn't be able to) save ar.rnat either. This is a problem
+ because if we're not careful, we could end up loading random NaT bits.
+ There are two cases:
+
+ (i) ar.bsp < ia64_rse_rnat_addr(jmpbuf.ar_bsp)
+ ar.rnat contains the desired bits---preserve ar.rnat
+ across loadrs and write to ar.bspstore
+
+ (ii) ar.bsp >= ia64_rse_rnat_addr(jmpbuf.ar_bsp)
+ The desired ar.rnat is stored in
+ ia64_rse_rnat_addr(jmpbuf.ar_bsp). Load those
+ bits into ar.rnat after setting ar.bspstore. */
