Call Python code from LLVM JIT
I write a language lexer/parser/compiler in python, that should run in the LLVM JIT-VM (using llvm-py) later. The first two steps are quite straightforward for now, but (even if I didn't start the compile-task yet) I see a problem, when my code…

Why does LLVM throw an "arguments of incompatible type" error when creating an array?
I am using LLVM and the llvmpy library.
My goal is to create something similar to the follow C code:

int b[] = {1, 2, 3};
int c[] = {1};
int* ptrs[] = {a, b, c};
The following is the outputted IR of the above excerpt:

How do I store a value in LLVM?
I am using LLVM's Python bindings - and, so far, I've been able to generate Constant values using LLVM. However, I am confused as to how to store them within an address.
This is probably a very basic question - how do I store a constant in memory?…
