|

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. */
