[LLVMdev] Dynamically loaded passes under OS X

[Robert L. Bocchino Jr.]

When I tried this a while back, the .so file wasn't being built on  
Mac OS X.  Now it looks like it is.  I got dynamic loading to work  
following the instructions in http://llvm.cs.uiuc.edu/docs/ 
WritingAnLLVMPass.html.  However, there was a typo in the  
instructions (it should say LOADABLE_MODULE = 1), and I fixed that  
and committed it.  I also fixed the sample/lib/sample Makefile to  
conform to these instructions.

So problem solved, thanks.
