+The LLVM native code generators are very stable, but do not currently support
+unwinding (exception throwing or <tt>longjmp</tt>ing), which prevent them from
+working with programs like the <tt>253.perlbmk</tt> in SPEC CPU2000.  The C
+backend and the rest of LLVM does support these programs however, so you can
+still use LLVM with them.  Support for unwinding will be added in a future
+release.
