[LLVMdev] make SHARED_LIBRARY=1 broken?

Hi,

Thanks for getting back to me.

I don't actually need opt dynamically linked but I do want shared libraries.
If run make without "SHARED_LIBRARY=1" I don't appear to get any
shared
libraries built or installed.

Is LLVM built as shared libraries supported? If so what's the correct build
procedure?
