So basically, is it possible to initialize the SelectionDAG and extract the lowering of getelementptr from it within a pass?<br><br><div class="gmail_quote">On Thu, Dec 8, 2011 at 11:00 AM, Ryan Taylor <span dir="ltr"><<a href="mailto:ryta1203@gmail.com">ryta1203@gmail.com</a>></span> wrote:<br>

I was unaware of its removal. I am still using 2.8. I grep'd the
source tree for that pass and found it on the header I mentioned; it
led me to believe the pass was still there.<br>
<br>
The transformation itself isn't complicated; doing it manually
should be simple.<div><div><br>

There is a GEPSplitterPass in the Scalar.h but not in the
LLVM_SRC/lib/Transforms/Scalar folder, there is no
GEPSplitterPass.cpp file. Is it possible to get this from 2.8 and
compile it and use it for 2.9?<br>

Looking at the release notes for 2.9, it appears that
GEPSplitterPass has been removed from 2.9. Is this the case,
can I access it anyways or no?<br>
<br>
Due to all the changes between versions of LLVM, it's not
timely to switch to any other version of LLVM, since the code
modifications would be too many. Any other ideas?

Yes, exactly along these lines, how do I use this
pass? It's not documented in the Transforms section of
