COMP3161/9164 21T3 Assignment 2 Type Inference for Polymorphic MinHS Version 2.1 Overview In this assignment you will implement a type inference pass for MinHS. The language used in this assignment differs from the language of the first assignment in two respects: it has a polymorphic type system, and it has aggregate data structures. The assignment

Microsoft PowerPoint – Week 11 2021 Week 11 Start at 12:05 as per usual Outline • Mid‐Sem run‐through • Programming in assembly • Labels/Subroutines/Stack Management policy • Addressing Modes Writing assembly programs • Hard! • You need to know/choose underlying data structure • Not clear just looking at memory what is happening • Give you some idea: 1. Understanding Assembly: Activity 3 week 8 2. Writing Assembly Writing assembly programs • How do you access data? • Subject for addressing modes • But give short intro here: • Look up AVR code • (http://ww1.microchip.com/downloads/en/DeviceDoc/Atmel‐0856‐ AVR‐Instruction‐Set‐ Manual.pdf ) • (https://canvas.sydney.edu.au/courses/17907/pages/week‐8?module_item_id=577689 ) Example • How do you translate (written in some high‐level language) this to assembly (start with .section .data): • A = 10 • B = [1, 2, 4, 10]
