[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

Hi Stefan,

No, I haven’t. Will try that later tonight.
Thanks!

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!!!

[llvm-dev] clang interpreter failed to materialize symbols

Hi Stefan,

I just tried it. Here is what I got:

Assertion failed: isa<X>(Val) && "cast<Ty>() argument

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

[llvm-dev] clang interpreter failed to materialize symbols

Hi Stefan,

I just tried the -jit-kind=orc-lazy with lli executable and it solves the
problem on Ubuntu 18.04 (still does not work on Windows 10). But this solution
is good enough for me now. Thanks again for your help!

Best Regards,
Igor

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!!!

Igor
