Dear Luis,

You should ask on llvmdev how to get the size of a pointer.  I think 
various transformations within LLVM need this information, so I imagine 
there is a way to get it.  However, I don't know off-hand how that is 
done in newer versions of LLVM.

Are you sure that the Module doesn't contain the pointer size anymore?  
Unless they added a pointer size intrinsic or ConstantExpr, I can't see 
how target-dependent transformations work without that information.  Is 
there a reason that using the DataLayout class (as SAFECode currently 
does) does not work anymore?

Regards,

John Criswell
