Sustainable Development Goals

Learning Goals

* Discuss the concept of compilers. [Familiarity]
* Understand the disposal of data in memory in execution time. [Familiarity]
* Translate between Abstract Syntax Trees and Intermediate Representation Trees. [Usage]
* Use abstract machines in code generation. [Usage]
* Understand the various forms of optimization that can be applied to a program, during it's compilation. [Familiarity]
* Identify the need and advantages or disadvantages of including garbage collection in a programming language. [Assessment]
* Determine the differences between the compilation process of imperative, functional and object-oriented languages. [Usage]
* Write a compiler for Abstract Syntax Trees which uses various optimization techniques and generates code for an abstract machine, starting by the translation to Intermediate Representation. [Assessment]
