Hi all,

Matt (CCd) and I are implementing Decoupled Software Pipelining as a
pass in LLVM. This pass requires constructing the Program Dependence
Graph (PDG) of a loop. We found a PDG implementation in an old release
of the poolalloc project:

https://llvm.org/svn/llvm-project/poolalloc/tags/RELEASE_14/lib/DSA/PgmDependenceGraph.cpp

Unfortunately, this code is too old to reuse with current versions of
LLVM. Is there a newer PDG implementation around somewhere that we can
use for our project?

Thanks,
David
