[llvm-dev] Error running clang++ generated bitcode in lli (original) (raw)

I am trying to generate a bit code from a c++ source code and running it through the just-in-time compiler. When I compile through the clang++ and generate binary executable it runs perfectly but when I generated the bitcode and tried running through the JIT with lli command it generated a run-time error. Could you please help me understand what's going on.

For example: Let example.cpp contains the following code:

#include

int main(){ std::cout << "\nHello World!"; return 0; }

I am using the following command to generate executable which runs perfectly fine.

clang++ example.cpp

I am using the following command to generate the bitcode:

clang++ -S -emit-llvm example.cpp

And then running through the JIT using the following command which generates run-time error:

lli example.ll

I am getting the following access violation error:
