Hi Stefan,
I just tried it. Here is what I got:
PS C:\Users\giv_u\source\repos\ConsoleApplication1\ConsoleApplication1> lli -jit-kind=orc-lazy .\ConsoleApplication1.bc
Assertion failed: isa<X>(Val) && "cast<Ty>() argument of incompatible type!", file C:\dev\llvm-project\llvm\include\llvm/Support/Casting.h, line 264

Thanks,
Igor

Hi Igor, not sure if that will work, but have you tried lli -jit-kind=orc-lazy ? The default is still MCJIT:

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!!!
