π: towards a simple formal semantic framework for compiler construction

This paper proposes {\pi}, a formal semantic framework for compiler construction together with program validation. {\pi} is comprised by {\pi} Lib, a set of programming languages constructs inspired by Peter Mosses' Component-Based Semantics and {\pi} Automata, an automata-based formalism to describe the operational semantics of programming languages, that generalizes Gordon Plotkin's Interpreting Automata.
