llvm

The LLVM (Low Level Virtual Machine) IR framework is mainly used to create compilers, code generators and other code manipulating tools.

LLVM IR with C and Linux using Docker

This guide will show you how to install and use LLVM IR with C and Linux using Docker.

Pull the official LLVM image from Docker Hub:
```
docker pull llvm
```
Run the LLVM image in a container, mounting the current directory to the container's /src directory:
```
docker run -it -v $(pwd):/src llvm
```
In the container, navigate to the /src directory:
```
cd /src
```
Compile and run your C code with LLVM IR:
```
clang -S -emit-llvm -o file.ll file.c
```
You can use lli to run the IR file, which is the just-in-time (JIT) compiler:
```
lli file.ll
```
You can also use opt for optimization, and llc to generate machine code:
```
opt -O3 -S file.ll -o file_opt.ll
llc file_opt.ll -o file.s
```
You can use gcc to link and generate the binary:
```
gcc file.s -o file
```
You can now run the binary:
```
./file
```
