Ok, thanks, this makes sense. But there is no way to get the SelectionDAG to do it for me via something like visitGetElementrPtr?

SelectionDAGBuilder::visitGetElementPtr uses the same algorithm you want to use, but it is specialized for building a SelectionDAG, which is lower level than LLVM IR. -Eli > > > On Thu, Dec 8, 2011 at 2:54 PM, Eli Friedman <eli.friedman at gmail.com> wrote: >> >> >...
