LLVM IR module in Zig

A minimal example to create and execute a LLVM IR module in Zig.

Install

First of all, you need to install LLVM and Zig according to your system.

Windows

with Scoop

scoop install llvm zig

MacOS

with Homebrew

brew install llvm zig

Tip

Tested successfully with LLVM 17.0.6 and Zig 0.11+.

Clone

git clone https://github.com/seyhajin/llvm-ir-zig

Alternatively, download zip from Github repository and extract wherever you want.

Build & Run

Note

For simplicity, the program uses LLVM's dynamic libraries installed in your environment.

Build and run program :

zig build run

Output:

Hello, world!
sum(2, 3)=5

LLVM IR Module

LLVM IR module equivalent of:

int sum(int a, int b) {
    return a + b;    
}

void main() {
    printf("Hello, world!\nsum(2, 3)=%d\n", sum(2, 3));
}
