Usage

See examples for more details.

use llvm::{Context, ExecutionEngine};

let context = Context::new();
let module = context    
    .create_module("example")
    .with_source_file_name("example.ts");
let function = module
    .create_function("main", context.i32_ty(), &[], false)
    .build(|builder| {
        builder.build_ret(&context.const_i32(42));
        Ok(())
    })
    .unwrap();

assert_eq!(
    module.to_string().trim(),
    r#"
; ModuleID = 'example'
source_filename = "example.ts"

define i32 @main() {
  ret i32 42
}
    "#.trim()
);

let engine = ExecutionEngine::new_mc_jit_compiler(module).unwrap();
let result = unsafe { engine.run_main(&[], &[]).unwrap() };

assert_eq!(result, 42);
