Lazarus: Where Compilers Meet Education Gonçalves, Rui Henriques, Pedro Rangel Ramalho, José Carlos Object-Oriented Programming Compilation SSA Optimization Virtual Machine IDE Lazarus is an intentionally compact platform featuring an optimizing compiler, a lightweight virtual machine and IDE integration. Its small size, lets students explore every compilation stage by experimenting with a compiler inspired by modern systems. At the core lies an incremental parser, that only re-parses the surrounding areas of the changed text in an IDE environment, and an SSA-based optimizer. The target machine is a register-based virtual machine, that mimics native architectures, and provides a debugger. This paper presents both the source language, and its register-based virtual machine, while discussing an often neglected feature in compiler design: the incremental parser.
