# Rim `llvm`

Rim is a tiny compiler that I've been working on for the past 2 weeks. Right now it just compiles the code to `llir` but I'm need to add a lot of stuff to it.

## Usage

```bash

# make sure you have llvm installed

$ git clone https://github.com/japrozs/rim_llvm.git

$ cd rim_llvm

$ make -j$(nproc)

$ ./out/rimc samples/basic.rm

```

## Example

[samples/basic.rm](samples/basic.rm)

```rust

fn my_fn(argument, list){

	let var_inside_function : int = 123;

}

let declaration : string = "this is a global constant declaration";

let number : int = 123123;

```

`output` 

```llvm

; ModuleID = 'samples/basic.rm'

source_filename = "samples/basic.rm"

@declaration = global [39 x i8] c"\22this is a global constant declaration\22"

define i32 @main() {

entry:

  %number = alloca i32, align 4

  store i32 123123, i32* %number, align 4

  ret i32 0

}

declare i8 @printf(i8 %0)

define i8 @my_fn(i8 %0) {

entry:

  %var_inside_function = alloca i32, align 4

  store i32 123, i32* %var_inside_function, align 4

}

```
