[LLVMdev] poolallocation error

[Prakash Prabhu]

Hi all,

I too am getting this error for x86_64 when I am trying to use the
Data Structure Analysis ...I svn upped both the llvm main branch and
the poolalloc today in the morning and recompiled everything from
scratch :

$ opt -load /home/pprabhu/llvm/llvm-install-x86-64/lib/libpoolalloc.so
-ds-aa < o.bc

opt: /home/pprabhu/llvm/llvm/lib/VMCore/PassManager.cpp:1418: virtual

llvm::Pass*): Assertion `(P->getPotentialPassManagerType() <
RequiredPass->getPotentialPassManagerType()) && "Unable to handle Pass
that requires lower level Analysis pass"' failed.

Is there something that I am missing on the command line ? Does anyone
use DSA actively now ?

Thanks for your time.
