LLANG

Basic LLVM based compiler with javascript-like syntax

• Static type checking
• Compiles to x86_64 object files
• C/asm/etc-interop (no varargs)
• Structures
• Functions
• Variables
• Pointers

Building

Requires llvm, clang, boost and gtest

Ubuntu/Debian

sudo apt-get install llvm clang libboost-all-dev libgtest-dev
cmake .
make run # build, compile example, link and run example
make llang # build binary file
make test # run tests
make lint # lint (style check)
make format # format all files

Example

import "stl.lll"

struct MyStruct {
  a: i64;
  b: i64;
  n: i64;
}

function fib(ms: MyStruct*): void {
  let out: str = malloc(10)
  ms->a = 1
  ms->b = 1
  for (let i: i64 = 0; i < ms->n; i += 1) {
    let temp: i64 = (*ms).b
    ms->b += ms->a
    ms->a = temp
    sprintf(out, "%lld", ms->b)
    puts(out)
  }
  free(out)
  return;
}

function main(argc: i64, argv: str*): i64 {
  let init: MyStruct = MyStruct {
    a: 1,
    b: 1,
    n: 10,
  };
  fib(&init)
  return 0
}
