[llvm-dev] clang interpreter failed to materialize symbols

Hello,

I am new to LLVM and what I am trying to do is to get a very simple
“hello-world” C++ program to compile to LLVM IR and then to run it using lli
tool.
So here is the program code (hello.cpp):
#include <iostream>
int main (int argc, char *argv[])
{
    std::cout << "Hello World!\n";
    return 0;
}
Below are the steps I do to achieve that goal:

  1.  clang++.exe hello.cpp -S -emit-llvm -o hello.ll (produces hello.ll about
307KB in size)
  2.  llvm-link.exe hello.ll -o hello.bc (produces the bit-code file about 79KB
in size).
  3.  lli.exe hello.bc (terminates with a segmentation fault). The dump is
below.

I understand that some symbols are not loaded (C++ standard library symbols). I
am not sure how I can specify the location of those symbols to lli tool (I tried
–extra-object option but no effect).
Could someone please let me know what am I missing or doing wrong?
Any help is greatly appreciated!!!

Thanks,
Igor

[llvm-dev] clang interpreter failed to materialize symbols

Hi Igor, not sure if that will work, but have you tried lli
-jit-kind=orc-lazy ? The default is still MCJIT:
https://github.com/llvm/llvm-project/blob/master/llvm/tools/lli/lli.cpp#L88
