Run-time Support - The Engine of Execution
The chapter elaborates on the execution phase of a program, focusing on run-time support, which includes mechanisms for memory management, function calling, and the dynamics of parameter passing. It outlines various methods of parameter transmission: pass by value, pass by reference, and pass by name, while also detailing how activation records and stack allocation play a crucial role in function execution management. Furthermore, it explains the complex orchestration behind a function call and return process, emphasizing the significance of activation records and the stack in modern programming.

What we have learnt
- Run-time support is essential for executing programs correctly.
- Parameter passing methods can influence function behavior and performance.
- Activation records are critical for managing function calls and maintaining execution context.
Key Concepts
- -- Runtime Support
- The mechanisms and data structures that enable program execution and proper management of memory.
- -- Parameter Passing
- The method by which data is transmitted to functions, including techniques like pass by value and pass by reference.
- -- Activation Record
- A block of memory that contains all information relevant to a function call, including local variables, parameters, and control links.
- -- Stack Allocation
- A memory management strategy where activation records are handled on a stack, allowing automatic allocation and deallocation.
- -- Calling Convention
- A sequence of operations established by the compiler that outlines how functions are called and how control returns to the caller.
