[llvm-dev] llvm interpreter error with polybench

[Rasha Omar 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:

Stack dump:

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