Open Source C Software Testing Tools

It read opengl pixel shader from txt file, and draw big square on whole screen using that shader. Like shadertoy.com

News: since 2015 we continue all related developments within Collective Knowledge Framework: http://github.com/ctuning/ck/wiki Alchemist plugin is a collection of plugins for GCC/LLVM for external and fine-grain code analysis and tuning. It is intended to to extract program properties for machine learning based optimization (see MILEPOST GCC); optimize programs at fine-grain level (such as unrolling, tiling, prefetching, etc); tune default optimization heuristic; gradually decompose program and detect performance or other anomalies; generate benchmarks particularly useful to train ML-based compilers. GCC plugin is licenced under GPLv3 licensed, while future LLVM plugins will be licensed under BSD license. Alchemist plugin is in a preliminary stage (based on MILEPOST ML plugin), so collaborations are very welcome!

A program for syntactically correct sentence generation. Guided by a Bison grammar file as input, it provides random or coverage testing sentences. The program can be used for compiler or parser testing or didactical purposes.
