RLLVM

LLVM alternativ

Example

use std::error::Error;
use rllvm::prelude::*;

fn main() -> Result<(), Box<dyn Error>>{
    let mut contxt = Context::new( Triple::host() )?;
    let func = contxt.add_function("add", vec![Type::u32, Type::u32], Type::u32);
    let asm = func.asm_func()?;

    let x = asm.arg(0).unwrap();
    let y = asm.arg(1).unwrap();

    func.ir.push( Return::new(*(x + y) ) );


    unsafe {
        let mut func: JitFunction<unsafe extern "C" fn(u32, u32) -> u32> = contxt.get_jit_function("add")?;
        let out = func.call(5, 5);

        println!("main() -> {}", out);
    }

    Ok(())
}

ToDo

Here is a bit of ToDo for my libary:

v0.1.2

• Starting high level ir struct
  • Use traits impl Compiler for Ir::Add<Var, Int> so i can overload the enum variants
  • Make it compilable
  • Implement mov, add, sub, mul, div | ints, floats
    • mov
    • add
    • sub
    • mul
    • div
    • ints
    • floats
  • Starting high level ir builder
    • via traits

v0.1.3

• Implement args to the high level ir
• Add option (in context) to compile to object file
• Naming convention
  • generate
  • parse
