+/* This implementation relies heavily on the Xtensa register window
+ mechanism. Setjmp flushes all the windows except its own to the
+ stack and then copies registers from the save areas on the stack
+ into the jmp_buf structure, along with the return address of the call
+ to setjmp. Longjmp invalidates all the windows except its own, and
+ then sets things up so that it will return to the right place,
+ using a window underflow to automatically restore the registers.
+
+ Note that it would probably be sufficient to only copy the
+ registers from setjmp's caller into jmp_buf. However, we also copy
+ the save area located at the stack pointer of setjmp's caller.
+ This save area will typically remain intact until the longjmp call.
+ The one exception is when there is an intervening alloca in
+ setjmp's caller. This is certainly an unusual situation and is
+ likely to cause problems in any case (the storage allocated on the
+ stack cannot be safely accessed following the longjmp). As bad as
+ it is, on most systems this situation would not necessarily lead to
+ a catastrophic failure. If we did not preserve the extra save area
+ on Xtensa, however, it would. When setjmp's caller returns after a
+ longjmp, there will be a window underflow; an invalid return
+ address or stack pointer in the save area will almost certainly
+ lead to a crash. Keeping a copy of the extra save area in the
+ jmp_buf avoids this with only a small additional cost. If setjmp
+ and longjmp are ever time-critical, this could be removed. */

+/* This implementation relies heavily on the Xtensa register window
+ mechanism. Setjmp flushes all the windows except its own to the
+ stack and then copies registers from the save areas on the stack
+ into the jmp_buf structure, along with the return address of the call
+ to setjmp. Longjmp invalidates all the windows except its own, and
+ then sets things up so that it will return to the right place,
+ using a window underflow to automatically restore the registers.
+
+ Note that it would probably be sufficient to only copy the
+ registers from setjmp's caller into jmp_buf. However, we also copy
+ the save area located at the stack pointer of setjmp's caller.
+ This save area will typically remain intact until the longjmp call.
+ The one exception is when there is an intervening alloca in
+ setjmp's caller. This is certainly an unusual situation and is
+ likely to cause problems in any case (the storage allocated on the
+ stack cannot be safely accessed following the longjmp). As bad as
+ it is, on most systems this situation would not necessarily lead to
+ a catastrophic failure. If we did not preserve the extra save area
+ on Xtensa, however, it would. When setjmp's caller returns after a
+ longjmp, there will be a window underflow; an invalid return
+ address or stack pointer in the save area will almost certainly
+ lead to a crash. Keeping a copy of the extra save area in the
+ jmp_buf avoids this with only a small additional cost. If setjmp
+ and longjmp are ever time-critical, this could be removed. */
