You can still do anything with them really. From
bugzilla's query help...
"SUSPENDED - This bug is not fixed, because it is
dependent on something that won't happen for a while,
but is planned. For example, there were C++ parsing
bugs dependent on the new C++ parser. These are marked
suspended, rather than closed, since they are expected
to be fixed once the new C++ parser exists."

Glad to see we're on the same page. I just didn't
think that the part about "being interested in
miscompilations" was quite right, since what we're
really interested in is miscompilations on the
new-regalloc branch...
Updated patch attached. If okay, could somebody please
apply to 3.4 branch/mainline.
Thanks,
Dara

Use a graph coloring register allocator. Currently this option is meant
