[llvm-dev] llvm interpreter error with polybench

Tim Northover via llvm-dev

I am using polybench linear-algebra kernels for analysis, using these commands:

$ clang-3.8 -I utilities -I linear-algebra/kernels/3mm utilities/polybench.c linear-algebra/kernels/3mm/3mm.c -S -emit-llvm
$ llvm-link 3mm.ll polybench.ll -o 3mmN.ll
$ llvm-dis 3mmN

When I ran the file using interpreter

 $ lli --debug -force-interpreter -stats 3mmN.ll 

The interpreter stopped interpreting after the main function return without interpreting the other functions. It aborts with this error:

lli: /home/rasha/llvm/llvm/include/llvm/ADT/ilist_iterator.h:139:      llvm::ilist_iterator<OptionsT, IsReverse, IsConst>::reference llvm::ilist_iterator<OptionsT, IsReverse, IsConst>::operator*() const [with OptionsT = llvm::ilist_detail::node_options<llvm::Instruction, true, false, void>; bool IsReverse = false; bool IsConst = false; llvm::ilist_iterator<OptionsT, IsReverse, IsConst>::reference = llvm::Instruction&]: Assertion `!NodePtr->isKnownSentinel()' failed.

Stack dump:

Is there another method to use polybench kernels with llvm interpreter?
