GNU lightning is a library that generates assembly language code at run-time; it is very fast, making it ideal for Just-In-Time compilers, and it abstracts over the target CPU, as it exposes to the clients a standardized RISC instruction set inspired by the MIPS and SPARC chips.

Ragel compiles executable finite state machines from regular languages. Ragel targets C, C++, Objective-C, D, Java and Ruby. Ragel state machines can not only recognize byte sequences as regular expression machines do, but can also execute code at arbitrary points in the recognition of a regular language. Code embedding is done using inline operators that do not disrupt the regular language syntax.

Integer overflow and wraparound are major causes of software vulnerabilities in the C and C++ programming languages. In this paper we present the as-if infinitely ranged (AIR) integer model, which provides a largely automated mechanism for eliminating integer overflow and integer truncation. The AIR integer model either produces a value equivalent to one that would have been obtained using infinitely ranged integers or results in a runtime constraint violation. Unlike previous integer models, AIR integers do not require precise traps, and consequently do not break or inhibit most existing optimizations.

You've got a syntax error somewhere in your code. It could be around line 15. Good luck finding it.

This document explains how to construct a compiler using lex and yacc. Lex and yacc are tools used to generate lexical analyzers and parsers. I assume you can program in C, and understand data structures such as linked-lists and trees.

re2c is a tool for writing very fast and very flexible scanners. Unlike any other such tool, re2c focuses on generating high efficient code for regular expression matching.

Clojure is a dynamic programming language that targets the Java Virtual Machine. It is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastruc

Oink is a collaboration of C++ static analysis tools. The C/C++ front-end for Oink is Elsa by Scott McPeak. Currently the main tool provided by Oink is CQual++, a polymorphic whole-program dataflow analysis for C++.
