bugpoint.safe.ll

testcase:
llvm-as bugpoint.safe.ll
llvm-as bugpoint.test.ll
llc -march=c bugpoint.safe.bc -o temporary.c
gcc -xc temporary.c -O2 -o ./bugpoint.safe.bc.cbe.c.so -fPIC -shared
-fno-strict-aliasing
echo "running lli with jit calling functions in bugpoint.safe.bc.cbe.c.so"
lli -load ./bugpoint.safe.bc.cbe.c.so < bugpoint.test.bc

output:
running lli with jit calling functions in bugpoint.safe.bc.cbe.c.so
LLVM ERROR: Program used external function '.' which could not be resolved!

possitive test to make sure the llvm ir for the testcase are correct:
echo "running using only lli with jit"
cat bugpoint.safe.ll > combined.ll
cat bugpoint.test.ll >> combined.ll
llvm-as combined.ll
lli < combined.bc

expected output:
running using only lli with jit
