⚙️ Implementation Deep Dive

🔧 Call Site Optimization Engine

// JIT-compiled function call handler  
fn jit_compile_function_call(call_site: &CallSite) -> CompiledFunction {  
    let mut builder = FunctionBuilder::new();  
    
    // Parameter handling optimization  
    for (index, param) in call_site.parameters.iter().enumerate() {  
        builder.emit_parameter(param.type, index);  
    }  
    
    // Inlining decision logic  
    if should_inline(call_site) {  
        return inline_function(call_site);  
    }  
    
    // Recursion optimization check  
    if is_tail_recursive(call_site) {  
        return optimize_tail_call(call_site);  
    }  
    
    // Standard compilation path  
    builder.compile(call_site)  
}  

🔄 Tail Recursion Optimization

// Converts tail recursion to iteration  
fn optimize_tail_call(recursive_call: &CallSite) -> CompiledFunction {  
    let mut loop_builder = LoopBuilder::new();  
    
    // Initialize parameters as loop variables  
    for param in &recursive_call.parameters {  
        loop_builder.add_loop_variable(param);  
    }  
    
    // Build loop condition  
    loop_builder.set_condition(recursive_call.exit_condition);  
    
    // Embed function body as loop content  
    loop_builder.set_body(recursive_call.function_body);  
    
    // Update parameters for next iteration  
    loop_builder.set_update(recursive_call.parameter_update);  
    
    loop_builder.finalize()  
}
