Welcome to liblfds, a portable, license-free, lock-free data structure library written in C.

There is no license. You are free to use this software in any way, for any purpose. Go forth and create wealth!

Recursion may provide no salvation of storage, nor of human souls; somewhere, a stack of the values being processed must be maintained. But recursive code is more compact, perhaps more easily understood– and more evil and hideous than the darkest nightmares the human brain can endure.

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.

Treehydra is a GCC plugin that provides a low level JavaScript binding to GCC's GIMPLE AST representation. Treehydra is intended for precise static analyses.

Sparse provides a set of annotations designed to convey semantic information about types, such as what address space pointers point to, or what locks a function acquires or releases.

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

The Hoard memory allocator is a fast, scalable, and memory-efficient memory allocator. Hoard is a drop-in replacement for malloc() that can dramatically improve application performance, especially for multithreaded programs running on multiprocessors.

Ragel compiles executable finite state machines from regular languages. Ragel targets C, C++, Objective-C, D, Java and Ruby.

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.

Supposedly significantly (10-20%) faster than GCC on x86-64. GPLed too, since it's derived from SGI's Pro64 IA-64 compiler.

A bunch of docs and links on building highly scalable servers

The GCC docs are pretty craptacular, so this was helpful

Apple's release notes on GCC 4, much more useful info the the FSF release notes

This looks like an exceedingly useful reference
