No not yet, the recommended solution is to compute overflow manually with 
arithmetic after you do the operations you need.  In time LLVM will be 
extended to support this capability.

You might want to try LLVM CVS.  I believe there are several fixes in CVS 
that were not in 2.0.  If that doesn't work, we will gladly accept patches 
to make it work.

The LLVM community consists of volenteers, and noone volenteered for 2.0 
:)
