DOLPHIN-FEW - An example of a Web system to analyze and study compilers behavior

DOLPHIN is a framework conceived to develop and test compiler components. DOLPHIN-FEW (Front-End for the Web) is the DOLPHIN module that integrates all Web-related functionalities. Initially conceived to monitor the behavior of some routines of the compilers back-end, it is, nowadays, also usable as a visual tool to teach how those code analysis, optimization, and code generation routines work. This paper introduces DOLPHIN-FEW, a software system that takes advantage of the web environment and associated technologies to be a powerful pedagogical tool to teach compiler construction topics
