Yes.  I believe both static and dynamic libraries are
built.

That's good to know.
:)

Patrick, I assume you want to write some sort of LLVM pass that uses 
DSA.  To get this to work on Cygwin/MingW, what you want to do is to 
write a tool that statically links in DSA and your pass(es).  You can 
take the source code to the pa tool (poolalloc/tools/Pa) and modify it 
accordingly.

I think this method is preferable over Anton's suggestion of linking DSA 
directly into opt because it prevents you from having a modified version 
of the LLVM tools to maintain.

Dear Patrick and Antron,

I've modified the Makefiles in the poolalloc module so that they do not 
build shared libraries on MingW or Cygwin.  Patrick, if you do an "svn 
up" you should be able to compile the poolalloc project now.

-- John T.

I suggest you stick to John's release_26 branch of poolalloc for now.
2.7 breaks poolalloc, and dsa is undergoing some changes.

The patch below adds dsa and some of poolalloc to opt.  It should be
simple enough to extend to all of poolalloc by adding more classes to
LinkDSA.h.
