Function compile_reg 

pub fn compile_reg(program: &ProgramData) -> RegChunk

Compile an AST program into register-based bytecode.

Register-based bytecode is more suitable for JIT compilation compared to stack-based bytecode.

Examples

use just::parser::JsParser;
use just::runner::jit;

let code = "var x = 5 + 3;";
let ast = JsParser::parse_to_ast_from_str(code).unwrap();
let chunk = jit::compile_reg(&ast);
