Hi Prakash, Unfortunately it looks like you need to do quite a bit of investigation into this. However, I hope I can provide some useful tips. 1. In general, lli and llc generate exact the same code except lli default to static codegen while llc defaults to dynamic-no-pic codegen. So try passing -relocation-model=dynamic-no-pic to lli. If this works, that means there are issues with

Hi Eli, Thanks for the reply. I tried with -Xlinker="-ldl ". However it does not seem to make a difference. It seems that when bugpoint is run with --run-jit, the linker args are not passed to gcc (from tools/bugpoint/ExecutionDriver.cpp) : if (InterpreterSel == RunLLC || InterpreterSel == RunCBE || InterpreterSel == CBE_bug || InterpreterSel == LLC_Safe) RetVal =
