I added a short paragraph in the updated patch:
http://gcc.gnu.org/ml/gcc-patches/2011-06/msg01922.html
+@defmac UNIQUE_UNWIND_CONTEXT
+
+Define this macro if the target only supports single unqiue unwind
+context. The default is to support multiple unwind contexts.
+
+@end defmac
This is the implementation detail and isn't required by the ABI.
With the unique unwind context, we can update the unwind
context format without breaking binary compatibility.
Thanks.
