How do I acquire that version of DSA that you've updated to mainline cvs? Do I still check out llvm-poolalloc, or is there a way to only check out DSA?

Does llvm-gcc support the -fPIC option? I am using LLVM on both 32 bit linux and 64 bit linux, if that matters. Regards, Ryan -- Ryan M. Lefever [http://www.crhc.uiuc.edu/~lefever/index.html]

I followed what you said and called verifyModule() with the AbortProcessAction option. verifyModule() returns false, but does not abort and does not print out any information about what caused the verification to fail.
